CAR T-cell therapy combined with autologous hematopoietic cell transplantation in patients with refractory/relapsed Burkitt Lymphoma

Burkitt lymphoma (BL) is a highly aggressive type of non-Hodgkin lymphomas that have a high likelihood of relapse and are highly refractory to initial treatment. While high-intensity chemotherapy has improved the outcomes, many adult patients still experience treatment failure, and effective salvage therapies are limited. This study retrospectively analyzed the outcomes of 21 relapsed or refractory (R/R) adult BL patients treated with chimeric antigen receptor T-cell (CAR-T) therapy, combined or not with hematopoietic cell transplantation (HCT), across four Chinese hospitals. Patients were grouped based on treatment strategies: autologous HCT followed by CAR T-cell therapy (auto-HCT+CART group, n=8), and CAR T-cell therapy alone (CART group, n=13). The auto-HCT+CART group demonstrated superior outcomes, with an overall response rate (ORR) of 87.5% and significantly higher 1-year overall survival (OS) and progression-free survival (PFS) rates compared to the CART group (p=0.014 and p=0.045, respectively). These findings suggest that combining auto-HCT with CAR-T therapy may enhance long-term disease control in R/R BL patients. These encouraging results highlight the need for further prospective studies to validate our data.

Improved outcomes of palliative radiotherapy combined with immune checkpoint inhibitors in recurrent or metastatic cervical cancers

BackgroundImmunotherapy provides a remarkable survival advantage for patients with recurrent or metastatic cervical cancer (R/M CC). However, the role of immunotherapy in combination with radiotherapy in R/M CC remains unclear. MethodsWe retrospectively analyzed factors affecting immunotherapy effectiveness in patients with R/M CC. Clinical outcomes including tumor response and patient survival were assessed. Kaplan-Meier curves with the log-rank test were employed to compare survival data. Cox regression analysis was utilized to investigate prognostic factors. ResultsA total of 65 R/M CC patients treated with immune checkpoint inhibitors were eligible for analysis. We found that immunotherapy combined with palliative radiotherapy showed a significant positive correlation with complete response (OR = 6.31; 95 %CI: 1.74–22.91; p = 0.005). The 36-month progression-free survival (PFS) rate (73.7 % vs 33.8 %, p = 0.0048) and 36-month overall survival (OS) rate (85.7 % vs 38.7 %, p = 0.0043) were also prominently increased. We further demonstrated that patients prolonged 36-month PFS rate (69.9 % vs 15.2 %; p < 0.001) and 36-month OS rate (64.6 % vs 39.7 %; p = 0.032) when they had more than 4 cycles of immunotherapy. Meanwhile, our findings showed that patients with only recurrence had longer 36-month OS rate (77.7 % vs 44.4 % vs 40.1 %; p = 0.024) compared to those with only metastasis and both. We also observed that patients with squamous carcinoma had higher 2-year PFS rate (57.9 % vs 14.6 %; p = 0.042) than those with other pathological subtypes (adenocarcinoma, adenosquamous carcinoma and neuroendocrine carcinoma). ConclusionsThe combination of immunotherapy and palliative radiotherapy increased complete response rates and improved survivals in recurrent or metastatic cervical cancer patients.

Sequential Conditioning With FLAMSA Does Not Improve Outcomes of Allogeneic Stem Cell Transplantation in Chronic Myelomonocytic Leukemia Patients

As with myelodysplastic syndromes (MDS), effective treatment options for Chronic myelomonocytic leukemia (CMML) are limited, and the optimal treatment approach remains undefined. Allogeneic stem cell transplantation (allo-SCT) is potentially curative therapy for patients with CMML. Sequential conditioning with FLAMSA was initially developed for refractory acute myeloid leukemia (AML) and has since been applied in the treatment of MDS and CMML. Data on optimal allo-SCT conditioning in CMML Patients is scarce. This retrospective study from the Department of Stem Cell Transplantation at the University Medical Center Hamburg, Germany, compared allo-SCT outcomes in CMML patients across three conditioning regimes: Thiotepa-Busulfan (TB), Sequential FLAMSA-Busulfan Fludarabine (FLAMSA-FB), and Treosulfan-Fludarabine (Treo-Flu). Sixty-nine consecutive patients with CMML who underwent allo-SCT between the years 2006-2022 were included in the study. Twenty-two received TB, 27 received FLAMSA-FB, and 20 received Treo-Flu conditioning. Transplant sources included matched related donors (MRD, 8 patients), mismatched related donors (MMRD, 8 all in the TB group), matched unrelated donors (MUD, 31), and mismatched unrelated donors (MMUD, 22) with significant group variations (p<0.001). Most patients received anti-T lymphocyte Globulin (ATLG) for graft versus host disease (GVHD) prophylaxis (TB 68%, FLAMSA-FB 93%, Treo-Flu 85%, p=0.08). CPSS-Molecular score was comparable between the groups. One TB patient experienced primary graft failure, but engraftment times were comparable across the groups. Although not statistically significant, the TB group showed a trend towards improved 3-year OS rates (80%) compared to FLAMSA-FB (37%) and Treo-Flu (55%) (p=0.05). The TB group also displayed significantly higher 3-year PFS rates (80%) compared to FLAMSA-FB (33%) and Treo-Flu (both 39%), (p=0.02). No significant differences were observed in 3-year non-relapse mortality (NRM) across the TB (20%), FLAMSA-FB (30%), and Treo-Flu (26%) groups (p=0.8). Interestingly, no TB patients relapsed at 3 years, contrasting with the FLAMSA-FB (41%) and Treo-Flu groups (30%, p=0.02). Lastly, cumulative incidences of acute and chronic GVHD were similar across groups. Our analysis suggests FLAMSA-FB does not improve transplant outcomes, however TB represents the preferred conditioning regimen for CMML patients undergoing allo-SCT. It demonstrates notable advantages in relapse prevention and leads to improved OS and PFS compared to FLAMSA-FB and Treo-Flu protocols.

A new treatment approach of toripalimab in combination with concurrent platinum-based chemoradiotherapy for locally advanced cervical cancer: A phase II clinical trial.

This study investigated the efficacy and safety of toripalimab in combination with concurrent platinum-based chemoradiation in patients with untreated locally advanced cervical cancer. Eligible patients received toripalimab 240 mg once every 3 weeks in combination with concurrent platinum-based chemoradiotherapy, followed by the maintenance of toripalimab once every 6 weeks up to 1 year. The primary endpoint was objective response rate (ORR). Secondary endpoints included 2-year and 3-year progression-free survival (PFS) rates, 3-year overall survival (OS) rate, and safety. Biomarker analysis of PD-L1 expression and genomic mutational analysis by next-generation sequencing were conducted, as well as PD-L1 expression on tumor biopsies. A total of 82 patients were enrolled. The median follow-up was 21 months (range, 5.2-44.5 months). The ORR and disease control rate were both 87.8% among the 82 patients. Median PFS and OS were not reached. A trend toward longer PFS was observed in the populations with a PD-L1 combined positive score ≥10, low tumor mutation burden and loss of heterozygosity in human leukocyte antigen (HLA LOH) detected populations. A total of 37 patients experienced treatment-related adverse events, of which 17 (20.7%) patients experienced grade 3 or higher adverse events. Collectively, toripalimab plus concurrent platinum-based chemoradiotherapy showed promising antitumor efficacy with acceptable safety profiles in patients with untreated locally advanced cervical cancer.

Treatment Outcomes and Prognostic Factors of Chemotherapy Combined With Radiation Therapy for Patients With Early-Stage Extranodal Natural Killer/T-Cell Lymphoma

BackgroundThis study aimed to assess the treatment outcomes, toxicity, and potential prognostic factors in patients with early stage extranodal natural killer/T-cell lymphoma treated with radiotherapy combined with chemotherapy. MethodsOne hundred and eighteen patients with Stage I/II extranodal natural killer/T-cell lymphoma who were treated with radiotherapy combined with chemotherapy were retrospectively analyzed between July 2003 and January 2019. The median dose was 50 Gy (range, 45–61.2 Gy). The Kaplan–Meier method was used to calculate progression-free survival and overall survival. The patients were scored according to their prognostic indices. ResultsThe overall and complete response rates were 93.2% and 82.2%, respectively. At a median follow-up of 43 months, the 5-year overall survival and progression-free survival rates were 73.9% and 68.4%, respectively. Adverse events of grade 3 or higher was observed in 20 patients (16.9%). Patients with primary disease in the Waldeyer's ring had poorer survival (P=0.015). Compared with anthracycline-based regimens, non-anthracycline-based regimens significantly improved the 5-year overall survival (76.6% vs. 54.8%, P=0.027) and progression-free survival (72.4% vs. 53.1%, P=0.013). After treatment, the 5-year overall survival rate was 78.6% in complete response patients versus 44.9% in non-complete response patients (P=0.003). For patients with low-and intermediate-low-risk according to the nomogram-revised risk index model, the complete response rate was 100%. When primary lesion data were added to the nomogram-revised risk index as the basis for another prognostic index (modified nomogram-revised risk index), the low-risk (zero to two risk factors) and high-risk (three or more risk factors) categories were noted (84.2% vs 62.2%, P=0.036). ConclusionPatients with early stage extranodal natural killer/T-cell lymphoma had high response rates and favorable survival rates with radiotherapy and non-anthracycline-based chemotherapy regimens. Patients who achieved complete response had better survival than those who did not. The extranodal natural killer/T-cell lymphoma-specific prognostic models may require further optimization.

Analysis of alkaline phosphatase and γ-glutamyltransferase after radiofrequency ablation of primary liver cancer: A retrospective study.

Changes in alkaline phosphatase (ALP) and γ-glutamyltransferase (GGT) levels in patients with primary liver cancer (PLC) after radiofrequency ablation (RFA). Hepatocellular carcinoma is a malignant tumor with high incidence worldwide. As a common local treatment, RFA has attracted much attention for its efficacy and influence on liver function. To investigate the effect of serum ALP and GGT levels on the prognosis of patients with PLC treated by RFA. The preoperative clinical data of 165 patients who were pathologically or clinically diagnosed with PLC and who received RFA in our hospital between October 2018 and June 2023 were collected. The chi-square test was used to compare the data between groups. The Kaplan-Meier method and Cox regression were used to analyze the associations between serum ALP and GGT levels and overall survival, progression-free survival (PFS) and clinical characteristics of patients before treatment. The 1-year survival rates of patients with normal (≤ 135 U/L) and abnormal (> 135 U/L) serum ALP before treatment were 91% and 79%, respectively; the 2-year survival rates were 90% and 68%, respectively; and the 5-year survival rates were 35% and 18%, respectively. The difference between the two groups was statistically significant (P = 0.01). Before treatment, the 1-year survival rates of patients with normal serum GGT levels (≤ 45 U/L) and abnormal serum GGT levels (> 45 U/L) were 95% and 87%, the 2-year survival rates were 85% and 71%, and the 5-year survival rates were 37% and 21%, respectively. The difference between the two groups was statistically significant (P < 0.001). Serum ALP [hazard ratio (HR) = 1.766, 95% confidence interval (95%CI): 1.068-2.921, P = 0.027] and GGT (HR = 2. 312, 95%CI: 1.367-3.912, P = 0.002) is closely related to the overall survival of PLC patients after RF ablation and is an independent prognostic factor. The 1-year PFS rates were 72% and 50%, the 2-year PFS rates were 52% and 21%, and the 5-year PFS rates were 14% and 3%, respectively. The difference between the two groups was statistically significant (P < 0001). The 1-year PFS rates were 81% and 56% in patients with normal and abnormal serum GGT levels before treatment, respectively; the 2-year PFS rates were 62% and 35%, respectively; and the 5-year PFS rates were 18% and 7%, respectively, with statistical significance between the two groups (P < 0.001). The serum ALP concentration (HR = 1. 653, 95%CI: 1.001-2.729, P = 0.049) and GGT (HR = 1.949, 95%CI: 1.296-2.930, P = 0.001) was closely associated with PFS after RFA in patients with PLC. The proportion of male patients with abnormal ALP levels is high, the Child-Pugh grade of liver function is poor, and the incidence of ascites is high. Among GGT-abnormal patients, the Child-Pugh grade of liver function was poor, the tumor stage was late, the proportion of patients with tumors ≥ 5 cm was high, and the incidence of hepatic encephalopathy was high. Serum ALP and GGT levels before treatment can be used to predict the prognosis of patients with PLC after RFA, and they have certain guiding significance for the long-term survival of patients with PLC after radiofrequency therapy.

Time to lymphoma treatment within 24 months in 'watch and wait' follicular lymphoma is associated with inferior outcomes: A multicentre analysis.

Some 'watch and wait' (W&W) FL patients suffer from rapid progression in a short term. Herein, we sought to identify these patients and also develop a risk score to screen them at diagnosis. Between 2008 and 2022, a total of 411 FL patients managed by the W&W strategy from 16 cancer centres were retrospectively enrolled in this study, and their time to lymphoma treatment (TLT) and progression-free survival (PFS) were evaluated. Thirty-five percent of W&W FL patients experienced TLT within 24 months (TLT24) after diagnosis. Their 5-year PFS rate was significantly lower than those without treatment at 24 months (62.3% vs. 89.5%). In multivariable analysis, five factors were identified as independent predictors of TLT24: stages III-IV, β2 microglobulin ≥3 mg/L, lymphocyte-to-monocyte ratio <3.8, bone marrow involvement and spleen enlargement (above umbilical line). Their AUCs for TLT24 were 0.76 (95% CI, 0.70-0.82) in the training cohort and 0.76 (95% CI, 0.67-0.85) in the validation cohort respectively. Risk groups were also associated with PFS (p < 0.001). In FL patients initially managed by W&W, TLT24 was associated with poor outcomes. This multivariable model helps screening for predicting TLT24, which may be useful to identify candidates for early interventional treatment.

The efficacy of second-line tyrosine kinase inhibitor for patients with metastatic non-clear cell renal cell carcinoma following first-line immune-oncology combination therapy.

Metastatic non-clear cell renal cell carcinoma (nccRCC) is a heterogeneous disease with a poor prognosis and is treated with immunotherapy (IO)-based combinations according to the clear cell renal cell carcinoma. Tyrosine-kinase inhibitors (TKIs), such as cabozantinib and axitinib, are commonly used as the 2nd line therapy after 1st line IO combination therapy, but their efficacy as 2nd line TKI therapy for nccRCC is unknown. In this study, we performed a retrospective multicenter analysis of nccRCC patients who were previously treated with IO combination therapy and received 2nd line TKIs. Among 254 patients enrolled in the Japanese multicenter retrospective study, 52 patients with nccRCC histology who received second-line TKIs were included in this study. Progression-free survival and overall survival (OS) from 2nd line TKIs were analyzed by log-rank test and Cox-proportional hazard model. Objective response rate (ORR) of 2nd line TKIs were analyzed. The 1-year PFS and OS rates were 25.0% (95% CI = 13.1-36.8) and 63.8% (95% CI, 48.0-75.9), respectively. No patients had a complete response, 11 had a partial response, and 18 had stable disease. ORR was 21.1%. IMDC poor risk and sunitinib as the 2nd line therapy were significantly associated with poor PFS. The 2nd-line TKI was effective for a small group of nccRCC patients previously treated with IO combination therapy, although this study was retrospectively analyzed with a small number of cases.

Efficacy of PD-1 inhibitor with neoadjuvant chemotherapy in hypopharyngeal and oropharyngeal cancer.

This study is aimed to evaluate the efficacy and safety of PD-1 inhibitors combined with neoadjuvant chemotherapy in patients with locally advanced hypopharyngeal and oropharyngeal cancer prior to surgical resection. This retrospective analysis included 42 patients diagnosed with locally advanced hypopharyngeal and oropharyngeal cancer. The efficacy, safety, survival, and laryngeal preservation rate were evaluated. A total of 42 patients were included in this retrospective analysis, of whom 28 had hypopharyngeal cancer and 14 had oropharyngeal cancer. Of the 42 patients, 14 (33.3%) achieved a pathological complete response (PCR) at the primary site, 20 (47.6%) achieved a major pathological response (MPR), and 8 (19%) had an incomplete pathological response (IPR) at the primary lesion. A PCR at both the primary site and the neck lymph nodes was observed in 9 patients (21.4%). The laryngeal preservation rate was 92.9% (26/28) in patients with hypopharyngeal cancer. The median follow-up time was 10.5 months. The median progression-free survival (PFS) was 26.42 months (95% CI, 23.416-29.424), and the median overall survival (OS) was 27.1 months (95% CI, 24.316-29.884). The 1-year PFS rate was 83.1%, and the 1-year OS rate was 85.9%. Combination therapy with PD-1 inhibitors and neoadjuvant chemotherapy has demonstrated superior efficacy and safety as a preoperative treatment for locally advanced hypopharyngeal and oropharyngeal cancer. Notably, this treatment regimen does not increase the risk of severe postoperative complications and has shown promising results in improving laryngeal preservation rates.

Characteristics, efficacy, and prognosis analysis of newly diagnosed marginal zone lymphoma.

To retrospectively analyze the characteristics of newly diagnosed marginal zone lymphoma (MZL) patients, evaluate the efficacy of different treatment regimens, and explore prognostic factors in the era of immunotherapy. We reviewed the clinical data of newly diagnosed MZL patients treated at the Department of Hematology, The First Hospital of Jilin University, from October 2013 to October 2023. Survival differences between groups were analyzed using the log-rank test, and prognostic factors were identified. A total of 265 newly diagnosed MZL patients were included, with a median age of 59 years (range 22-90). The most common pathological type was mucosa-associated lymphoid tissue (MALT) lymphoma, accounting for 66.0% of cases. Among the 147 MZL patients included in the efficacy analysis, the median follow-up was 43.4 months. Both the median progression-free survival (PFS) and overall survival (OS) were not reached. The 5-year PFS and OS rates were 76.0% and 86.6%, respectively. Patients who achieved complete response (CR) after induction therapy had significantly better PFS (P=0.0045), OS (P<0.001), and time to next treatment (TTNT) (P=0.0045) compared to those who did not achieve CR. A subgroup analysis was conducted on 51 MZL patients with high tumor burden who received ≥4 cycles of treatment. It was found that the CR rate (CRR) in patients receiving obinutuzumab (G) ± chemotherapy was significantly higher than in those receiving rituximab (R) ± chemotherapy (93.8% vs. 48.6%, P=0.002). Multivariate analysis revealed that disease progression or death within 24 months of initial treatment (POD24) was an independent risk factor affecting OS (P<0.001). Patients who experienced POD24 had a median survival of only 19.7 months, with a 3-year OS rate of just 37.6%, whereas those without POD24 had a 3-year OS rate of 97.3%. MZL is predominantly seen in middle-aged and elderly patients and is a specific indolent B-cell lymphoma, with MALT lymphoma being the most common subtype. Achieving CR after induction therapy significantly prolongs survival in MZL patients. Compared to R ± chemotherapy, G ± chemotherapy achieves a higher CRR in high tumor burden MZL patients. In the era of immunotherapy, POD24 is an independent prognostic factor for MZL.

Definitive particle therapy using protons or carbon ions for dedifferentiated liposarcoma

BackgroundParticle therapy is effective for the treatment of soft tissue sarcomas. However, the clinical outcomes of definitive particle therapy, particularly for dedifferentiated liposarcoma (DDLS), remain unknown. PurposeTo analyze the treatment outcomes of proton and carbon ion particle therapies for DDLS. MethodsWe retrospectively included patients with DDLS who were treated with particle therapy between 2008 and 2022. The local control (LC), progression-free survival (PFS), and overall survival (OS) rates were evaluated. ResultsFifty-seven patients were included in this analysis. The median patient age was 68 years (range, 36–91 years). The most common tumor site was the retroperitoneum (n = 37), with a median gross tumor volume (GTV) of 181 cm3. Twenty-nine patients received proton therapy, and 28 patients received carbon ion therapy. The most common fractionation dose was 70.4 Gy (relative biological effectiveness) in 32 fractions (72.7 Gy equivalent dose in 2 Gy fractions [EQD2]). The median follow-up time was 33 months (range, 1–128 months). The 3-year LC, PFS, and OS rates were 73.1 %, 44.6 %, and 70.6 %, respectively. Patients who received a higher prescribed dose (≥72.7 Gy EQD2) showed significantly better LC (p = 0.04) than did those who received a lower prescribed dose. Moreover, those with a larger GTV (≥181 cm3) had significantly worse OS (p = 0.04) than did those with a smaller GTV. Late adverse events occurred in five (9 %) patients. ConclusionsParticle therapy using protons or carbon ions for the treatment of DDLS is safe and provides good OS and LC. However, further studies with longer follow-up periods and larger cohorts are warranted.

Neoadjuvant chemoradiotherapy versus neoadjuvant chemotherapy for initially unresectable locally advanced colon cancer: short-term outcomes of an open-label, single-centre, randomised, controlled, phase 3 trial

Neoadjuvant chemotherapy (NACT) is commonly used to downstage the tumor in locally advanced colon cancer (LACC) and improve the R0 resection rate. Neoadjuvant chemoradiotherapy (NACRT) is the standard treatment for locally advanced rectal and esophageal cancers, but its benefits in LACC remain poorly understood. This study aimed to compare the effects and safety of NACRT and NACT on R0 resection and survival rates in initially unresectable LACC. This was an open-label, single-center, randomized, controlled trial conducted between May 11, 2019 and May 30, 2022. Forty-five patients with initially unresectable LACC were randomly allocated to the NACT (control, n=20) or NACRT (research, n=25) group. The NACT group received XELOX (oxaliplatin 100-130mg/m2, qd, d1, every 3 weeks; and capecitabine 1000mg/m2, bid, d1-d14, every 3 weeks) for 4 cycles. The NACRT group, in addition to chemotherapy, received daily irradiation (GTV 45-50Gy/25F; CTV 42.5-45Gy/25F). Surgery was scheduled 6-12 weeks after neoadjuvant treatment and adjuvant chemotherapy was administered if the patient developed resectable LACC. The primary endpoint was the 5-year overall survival (OS) rate. The secondary outcomes included the 3-year progression-free survival (PFS) and R0 resection rates. This study was registered with ClinicalTrials.gov (NCT03970694). In short-term outcome analysis, NACRT significantly improved the R0 resection rate (80% for NACRT vs. 20% for NACT, P<0.001). The NACRT and NACT groups had a 3-year OS of 87.6% and 75% (P=0.037) and a 3-year PFS of 76% and 45% (P=0.049), respectively. The 5-year OS was not reached. In the NACRT group, no local or regional recurrence was observed in patients who underwent surgery during the follow-up period, compared to two patients in the NACT group. Both NACT and NACRT were well tolerated, with no significant differences in severe adverse events. The most commonly observed grade 3-4 AE was myelosuppression (39% for NACRT and 47% for NACT, P=0.609). No grade 5 AEs were observed between the two groups. Adding radiation to NACT increased the R0 resection rate, prolonged the PFS, and potentially improved OS in selected patients with initially unresectable LACC. The trial findings indicate that this approach is safe, feasible, and may confer a survival benefit.

Efficacy and safety of transcatheter arterial chemoembolization followed by hepatic arterial infusion chemotherapy combined with TKI and PD-1 inhibitors as first-line treatment for advanced hepatocellular carcinoma

To evaluate the efficacy and safety of transcatheter arterial chemoembolization (TACE) followed by hepatic arterial infusion chemotherapy (HAIC) combined with TKI drugs and PD-1 inhibitors as the first-line treatment for advanced hepatocellular carcinoma (HCC). We retrospectively analyzed the data of 70 patients with advanced HCC treated in the Department of Oncology of Guangdong Provincial Hospital of Integrated Traditional Chinese and Western Medicine between July, 2020 and June, 2023. 23 of the patients received TACE combined with HAIC and TKI (TACE+HAIC+ TKI group) and 47 received TACE combined with HAIC, PD-1 inhibitors and TKI (TACE+HAIC+PD-1+TKI group). The clinical characteristics, laboratory test results, efficacy, outcomes and adverse events of the patients were compared between the two groups. The TACE+HAIC+TKI and TACE+HAIC+PD-1+TKI groups had significantly different objective remission rates (ORR; 60.87% vs 36.17%, P=0.031), comparable disease control rates (95.65% vs 93.62%, P=0.068), and different median progression-free survival (PFS) time (10.2 vs 11.8 months, P=0.003) and median overall survival (OS) time (15.7 vs 19.5 months, P=0.035). After propensity score matching (PSM), the median PFS and OS time of the two groups was 10.1 vs 14.5 months (P= 0.024) and 14.2 vs 21.2 months (P=0.221), respectively. The 1-year PFS rates of the 2 groups were 24.0% vs 52.2%, and the 1-, 2-and 3-year OS rates were 72.3% vs 93.1%, 23.9% vs 63.8%, and 23.9% vs 36.5%, respectively. The incidence of proteinuria was significantly higher in TACE+HAIC+PD-1+TKI group than in TACE+HAIC+TKI group (21.28% vs 0, P=0.025), but the incidences of grade 3-4 treatment-related adverse events were all similar between the two groups. The first-line treatment with TACE+HAIC+PD-1+TKI is safe and effective for advanced HCC and can significantly prolong the survival of the patients.

Neuroblastoma with high ASPM reveals pronounced heterogeneity and poor prognosis

ObjectiveWe explored the preliminary value of abnormal spindle-like microcephaly- associated (ASPM) protein in aiding precise risk sub-stratification, prediction of metabolic heterogeneity, and prognosis of neuroblastoma (NB).MethodsThis retrospective study enrolled newly diagnosed patients with NB who underwent positron emission tomography/computed tomography (PET/CT) before therapy, and tumor tissue was collected after surgery. Regression analysis was used to evaluate ASPM expression and risk stratification in patients with NB. The expression levels of ASPM, clinical information, and PET/CT text features were analyzed using univariate and multivariate survival analyses. Finally, a correlation analysis was used to explore the relationship between ASPM and tumor metabolic heterogeneity.ResultsThere were 48 patients with NB in this study (35 boys and 13 girls); 22 patients progressed and 16 died. We found that the level of ASPM was highly associated with risk stratification (OR = 5.295, 95%IC: 1.348–41.722, p = 0.021). Patients with NB and high-risk stratification with high ASPM level had a lower 3-year progression-free survival (PFS) rate (14.28%) and 1-year PFS rate (57.14%) than those with low ASPM level (57.14% and 93.75%, respectively). Using univariate and multivariate survival analyses, this study revealed that ASPM and LDH were independent risk factors for both PFS and overall survival (OS), whales GLZLM_ZLNU was only a risk factor for PFS.ConclusionASPM holds promise as a novel biomarker for refining current risk stratification and predicting prognosis in neuroblastoma. Elevated levels of ASPM, LDH, and GLZLM_ZLNU may be associated with poorer survival outcomes in neuroblastoma patients.

Efficacy and safety analysis of the OR-CHOP regimen for the treatment of MCD subtype diffuse large B cell lymphoma in the real-world setting

Objective: To investigate the efficacy and safety of orelabrutinib combined with R-CHOP in the treatment of MCD subtype diffuse large B cell lymphoma (DLBCL) . Methods: Twenty-three MCD subtype patients whose gene-subtype classification was based on baseline tumor tissue and/or baseline plasma using the LymphGen algorithm from June 2022 to June 2023 in the First Affiliated Hospital of Nanjing Medical University were retrospectively enrolled in the analysis. All patients were treated with R-CHOP or R-miniCHOP in Course 1, OR-CHOP or OR-miniCHOP (21 days for one course) in Courses 2-6, and R-monotherapy in Courses 7-8. Results: Of the 23 patients, the median age was 58 years (range: 30-81 years), and 11 (47.8% ) aged >60 years. Fifteen cases (65.2% ) had international prognostic index (IPI) scores of 3 to 5. The top 10 mutated genes in the gDNA tissues were PIM1 (78.3% ), MYD88 (69.6% ), ETV6 (43.5% ), BTG1 (39.1% ), CD79B (43.5% ), HIST1H1E (39.1% ), BTG2 (34.8% ), KMT2D (30.4% ), CD58 (26.1% ), and CDKN2B (21.7% ). The consistency rate of the tissue and plasma mutations was 80%, while the baseline plasma ctDNA burden was closely correlated with the LDH levels and IPI scores (P<0.05). All patients received 5 courses of OR-CHOP regimens. The mid-term (after 3 courses) evaluation showed that the overall response rate (ORR) was 100% (23/23), with 22 patients (95.65% ) achieving complete remission (CR), and 1 patient (4.35% ) achieving partial remission (PR). The ORR after the end of treatment (EOT) was 95.65% (22/23). Moreover, 21 patients (91.30% ) obtained CR, 1 patient (4.35% ) obtained PR, and 1 patient (4.35% ) obtained progression disease (PD). Of the 21 patients who had the dynamic EOT-ctDNA burden, only four patients (19.0% ) did not achieve EOT-ctDNA clearance, while the other 17 patients (81.0% ) achieved EOT-ctDNA clearance. The median follow-up time was 20.8 (15.3-30.0) months, while the median progression-free survival (PFS) and overall survival (OS) were not reached. The 2-year PFS rate was 71.8% (95% CI 54.7% -94.2% ), while the 2-year OS rate was 91.3% (95% CI 80.5% -100.0% ). Furthermore, the OR-CHOP regimen was generally well tolerated during clinical use, with hematological toxicity being the main adverse effect. Conclusion: This study revealed that the OR-CHOP regimen can be used as an effective and safe first-line treatment for MCD subtype DLBCL.

The Role of Local Prostate and Metastasis-Directed Radiotherapy in the Treatment of Oligometastatic Prostate Cancer.

Background/Objectives: Oligometastatic prostate cancer (OMPC) represents an early stage of metastatic disease characterized by a limited number of lesions. Recent advancements in imaging and treatment have revived interest in personalized therapies, including metastasis-directed radiotherapy (OMDRT) and primary prostate radiotherapy (PPR). This study evaluates the impact of OMDRT timing and the role of PPR on survival outcomes in OMPC patients; Methods: In this retrospective cohort study, 82 patients with OMPC who underwent OMDRT between 2010 and 2019 were analyzed. Patients were classified based on OMDRT timing (early vs. late) and disease type (synchronous vs. metachronous). Progression-free survival (PFS) and overall survival (OS) were the primary endpoints, assessed via Kaplan-Meier analysis and Cox proportional hazards models; Results: Among the patients, 36 (43.9%) had synchronous and 46 (56.1%) had metachronous OMD. With a median follow-up of 32 months, the 5-year PFS and OS rates were 77.5% and 88.5%, respectively. Early OMDRT significantly improved PFS (HR 0.461, 95% CI: 0.257-0.826, p = 0.009) and OS (HR 0.219, 95% CI: 0.080-0.603, p = 0.003). Subgroup analysis showed the most favorable outcomes for synchronous OMD patients receiving early OMDRT, with a median PFS of 22.2 months and a 5-year survival rate of 42.1%. The treatment of the primary prostate provided a survival benefit in the OS of synchronous OMD patients (5-year 83.1% vs. 50%, p = 0.025), and there was a further improvement in OS after PPR (5-year 87.7% vs. 50%, p = 0.015). Conclusions: Early OMDRT significantly enhances survival outcomes in OMPC, in both synchronous and metachronous cases. The integration of PPR can further improve results, emphasizing the importance of early intervention and personalized treatment strategies. To more definitively clarify our findings across various clinical situations, further studies with larger cohorts or prospective designs are necessary.

Efficacy and safety of concurrent chemoradiotherapy with paclitaxel-based or S-1 regimens in treating elderly patients with esophageal squamous cell carcinoma: A multi-center propensity-score matched study

BackgroundElderly patients with esophageal cancer can benefit from concurrent chemoradiotherapy (CCRT). However, the optimal concurrent chemotherapy regimen remains undetermined. We aimed to compare the efficacy and safety of CCRT with paclitaxel-based or S-1 regimens in treating elderly patients with esophageal squamous cell carcinoma (ESCC). MethodsFrom January 2016 to November 2022, a total of 349 patients aged 70 and above with ESCC were included. The patient population was divided into two treatment groups: patients receiving paclitaxel-based CCRT were allocated to the TP group, and those receiving S-1 regimen CCRT were allocated to the S-1 group. Propensity score matching (PSM) was used to balance potential biases. Survival outcomes, overall response rate, and treatment-related toxicities were assessed. ResultsAfter PSM, there were 82 patients in each group. The median follow up of the surviving patients was 42.6 months (IQR 28.0–58.8 months). The 2-year overall survival (OS) rate (71.4% vs 65.4%; log-rank P = 0.010) and progression-free survival (PFS) rate (64.4% vs 58.0%; log-rank P = 0.048) were significantly higher in the TP group. Compared with the S-1 group, the TP group experienced a higher rate of grade 3 and above hematologic toxicities, such as leukopenia (47.6% vs 15.9%, P < 0.001) and neutropenia (35.4% vs 6.1%, P < 0.001). One patient in the TP group and two patients in the S-1 group had grade 5 toxic effects. ConclusionsOur findings suggest that paclitaxel-based CCRT was well tolerated in elderly patients with ESCC and provided significant survival benefits over S-1 regimen.

Patterns of treatment failure in patients with sinonasal squamous cell carcinoma after chemoradiotherapy.

To investigate the failure patterns based on precision radiation treatment and to determine the predictive factors of treatment failure for sinonasal squamous cell carcinoma (SNSCC) patients. This was a retrospective study that included 214 cases of treatment failure from 441 consecutive patients. Two experienced radiation oncologists evaluated the tumour volume of cases with local recurrence. The 5-year overall survival (OS), progression-free survival (PFS) rates, and distant-metastasis-free survival (DMFS) were estimated. Investigations were performed on the factors that predicted local failure or distant metastasis. About 140 (31.7%) patients developed local recurrence, 24 (5.4%) experienced regional failure, and 65 (14.7%) underwent distant metastasis. In-field, marginal, and out-of-field failures occurred in 55.7% (78/140), 33.6% (47/140), and 10.7% (15/140) of patients with local recurrence, respectively. In logistic regression analysis, factors statistically significant for total local failure included treatment mode (P < .01), chemotherapy (P < .01), and surgical margins (P < .01). Primary tumours with poor differentiation (P = .018) and R2 resection margin (P = .009) were more prone to develop distant failure. The 5-year OS, PFS, and DMFS rates were 57.8%, 52.0%, and 56.7% for the whole cohort. In univariate and multivariate analysis, the skull base involvement was an independent predictor for poorer OS and PFS; orbital invasion was an independent predictor for poorer OS. Local recurrence and distant metastasis were the most common failure modes. Treatment mode, chemotherapy, and surgical margins were related to local recurrence. Poor differentiation and R2 resection margin were predictors for distant failure. Local recurrence is the most common failure pattern in patients with SNSCC who accepted chemoradiotherapy, and marginal and out-of-field failures occurred in 44.3% of patients with local recurrence.

Impact of critical illness on continuation of anticancer treatment and prognosis of patients with aggressive hematological malignancies

BackgroundMaintaining the dose-intensity of cancer treatment is an important prognostic factor of aggressive hematological malignancies. The objective of this study was to assess the long-term outcomes of intensive care unit (ICU) survivors with acute myeloid leukemia (AML) or aggressive B-cell non-Hodgkin lymphoma (B-NHL) with emphasis on the resumption of the intended optimal regimen of cancer treatment.Patients and methodsWe conducted a retrospective (2013–2021) single-center observational study where we included patients with AML and B-NHL discharged alive from the ICU after an unplanned admission. The primary endpoint was the change in the intended optimal cancer treatment following ICU discharge. Secondary endpoints were 1-year progression-free survival and overall survival rates. Determinants associated with modifications in cancer treatment were assessed through multivariate logistic regression.ResultsOver the study period, 366 patients with AML or B-NHL were admitted to the ICU, of whom 170 survivors with AML (n = 92) and B-NHL (n = 78) formed the cohort of interest. The hematological malignancy was recently diagnosed in 68% of patients. The admission Sequential Organ Failure Assessment (SOFA) score was 5 (interquartile range 4–8). During the ICU stay, 30 patients (17.6%) required invasive mechanical ventilation, 29 (17.0%) vasopressor support, and 16 (9.4%) renal replacement therapy. The one-year survival rate following ICU discharge was 59.5%. Further modifications in hematologic treatment regimens were required in 72 patients (42%). In multivariate analysis, age > 65 years (odds ratio (OR) 3.54 [95%-confidence interval 1.67–7.50], p < 0.001), ICU-discharge hyperbilirubinemia > 20 µmol/L (OR 3.01 [1.10–8.15], p = 0.031), and therapeutic limitations (OR 16.5 [1.83–149.7], p = 0.012) were independently associated with modifications in cancer treatment. Post-ICU modifications of cancer treatment had significant impact on in-hospital, 1-year overall survival and progression-free survival.ConclusionThe intended cancer treatment could be resumed in 58% of ICU survivors with aggressive hematological malignancies. At the time of ICU discharge, advanced age, persistent liver dysfunction and decisions to limit further life-support therapies were independent determinants of cancer treatment modifications. These modifications were associated with worsened one-year outcomes.

Paclitaxel, Ifosfamide, and Cisplatin as Initial Salvage Chemotherapy for Germ Cell Tumors: Long-Term Follow-Up and Outcomes for Favorable- and Unfavorable-Risk Disease.

Paclitaxel, ifosfamide, and cisplatin (TIP) is an established salvage regimen for germ cell tumors (GCT) on the basis of a phase II trial, but efficacy on a large patient cohort including patients with unfavorable risk features and long-term outcomes has not been reported. Herein, we report updated treatment efficacy and long-term follow-up with TIP. Patients with GCT who received TIP after cisplatin-based chemotherapy were eligible. Favorable response (complete response or partial response with negative tumor markers), overall survival (OS) and progression-free survival (PFS) rates, relapse, and toxicity were determined. Disease was reclassified according to the International Prognostic Factor Study Group (IPFSG) score. Of the 104 patients, 87 had favorable risk factors and 17 had at least one unfavorable factor by Memorial Sloan Kettering Cancer Center (MSKCC) criteria. Ten patients were treated for a second gonadal primary GCT. With a median follow-up of 8.9 years, the 5-year PFS and OS rates were 66% (95% CI, 55 to 74) and 69% (95% CI, 59 to 77), respectively. Among 87 patients with favorable-risk disease, 69 (79%) achieved a favorable response with 5-year PFS and OS rates of 67% (95% CI, 56 to 76) and 72% (95% CI, 61 to 80), respectively. Among 17 patients with MSKCC unfavorable-risk disease, 13 (76%) achieved a favorable response with 5-year PFS and OS rates of 59% (95% CI, 33 to 78) and 56% (95% CI, 28 to 76), respectively. After IPFSG reclassification, 5-year PFS and OS rates for patients with ≤intermediate-risk disease were 75% (95% CI, 50 to 89) and 73% (95% CI, 55 to 85), respectively. TIP is an effective second-line regimen for patients with GCT. Similar outcomes were observed in patients with favorable- and unfavorable-risk disease. The randomized TIGER trial (ClinicalTrials.gov identifier: NCT02375204) comparing TIP with high-dose chemotherapy will determine the optimal second-line treatment approach.
