Mindfulness-based stress reduction training and supplemented Jinshui Liujun decoction promote recovery in patients with non-small cell lung cancer

BACKGROUND Conventional chemotherapy (CC) administered to patients with non-small cell lung cancer (NSCLC) often causes adverse effects, such as cardiopulmonary dysfunction and immune system imbalance. Patients may experience anxiety and depression during the perioperative period due to various factors, such as treatment costs and cancer recurrence risks, thereby compromising the overall quality of life. Consequently, we hypothesized that integrating mindfulness-based stress reduction training (MSRT) with Jinshui Liujun decoction may mitigate negative emotions and promote recovery in patients with NSCLC. AIM To explore the effects of MSRT and Jinshui Liujun decoction on the immune function and emotional state of NSCLC patients. METHODS A retrospective clinical study was conducted involving 92 patients with stage IIIb-IV NSCLC; 35 patients in the control group (CG) received CC therapy (combination of pemetrexed and carboplatin), and 57 patients in the treatment group (TG) received MSRT-assisted flavored Jinshui Liujun decoction (FJLD) in addition to CC. We evaluated the survival time, Karnofsky performance status, treatment efficacy, traditional Chinese medicine syndrome score, immune function, negative emotional level, and adverse reactions of the CG and TG. RESULTS Median progression-free survival, Karnofsky performance status, and clinical efficacy of the TG were superior to those of the CG (P < 0.05). Symptoms of cough, weakness, bloody sputum, shortness of breath, and chest pain significantly decreased in the TG compared to that in the CG (P < 0.05). In the TG, MSRT + FJLD treatment increased the numbers of CD3+ and CD4+ immune cells, effectively reduced the number of CD8+ cells, and enhanced the CD4+/CD8+ ratio, thereby restoring the immune function of patients. In the TG, the self-rating anxiety scale and self-rating depression scale scores decreased significantly. There was no statistically significant difference in the incidence of adverse reactions between the CG and TG (P > 0.05). CONCLUSION MSRT + FJLD proved to be an effective treatment for patients with NSCLC.

Treatment-related skin reactions in enfortumab vedotin as a surrogate marker of survival and treatment response.

Treatment-related skin reactions (TRSRs) induced by enfortumab vedotin (EV) targeting nectin-4 are among the most common adverse events. However, their association with survival and treatment response is poorly understood. We retrospectively identified patients who received EV from December 2021 to April 2023 at Nagoya University Hospital and its affiliated facilities and extracted clinical data from their medical records. We evaluated cancer-specific survival (CSS) and progression-free survival (PFS) as survival outcomes and overall response rate (ORR) and disease control rate (DCR) as treatment responses between patients with and without TRSRs. In total, 67 eligible patients were identified. Thirty-four patients experienced TRSRs, and the remaining 33 did not experience TRSRs. The median follow-up period was 8 months. Patients in the TRSRs group demonstrated significantly longer median CSS (15 vs. 8 months; p = 0.003) and median PFS (10 vs. 5 months; p < 0.001) than the non-TRSRs. Regarding treatment response, the patients in the TRSRs group showed a favorable, albeit nonsignificant, treatment response trend compared with those in the non-TRSRs group (ORR, 73.5% vs. 51.5%; p = 0.107; DCR, 91.2 % vs. 81.8%; p = 0.444). Patients with TRSRs demonstrated more prolonged survival and superior treatment responses to EV treatment. The role of TRSR as a surrogate marker of EV's efficacy should be further explored in prospective and sufficiently powered studies.

Clinical and biomarker analyses of SHR-1701 combined with famitinib in patients with previously treated advanced biliary tract cancer or pancreatic ductal adenocarcinoma: a phase II trial

Advanced biliary tract cancer (BTC) and pancreatic ductal adenocarcinoma (PDAC) have poor prognoses and limited treatment options. Here, we conducted this first-in-class phase II study to evaluate the efficacy and safety of SHR-1701, a bifunctional fusion protein targeting programmed death-ligand 1 (PD-L1) and transforming growth factor-beta (TGF-β), combined with famitinib, a multi-targeted receptor tyrosine kinase inhibitor, in patients with advanced BTC or PDAC who failed previous standard treatment (trial registration: ChiCTR2000037927). Among 51 enrolled patients, the BTC cohort showed an objective response rate (ORR) of 28% (including 2 complete responses) and a disease control rate (DCR) of 80%, with a median progression-free survival (mPFS) of 5.1 months and a median overall survival (mOS) of 16.0 months. In the PDAC cohort, the ORR was 15% (2 complete responses), with a DCR of 60%, and the mPFS and mOS were 2.1 months and 5.3 months, respectively. Grade 3 or 4 treatment-related adverse events (TRAEs) occurred in 29.4% of patients, with no grade 5 TRAEs reported. Exploratory analyses revealed that primary tumor resection history, peripheral blood immunophenotype changes, and distinct immune-metabolic profiles were associated with treatment benefits. An immune/metabolism score integrating the features of six genes was developed as a predictive biomarker for immunotherapy response in multiple cohorts, allowing for the selection of patients most likely to experience positive outcomes from this therapy regimen. In conclusion, our study provides proof-of-concept data supporting the potential of SHR-1701 plus famitinib as an effective and safe subsequent-line therapy for refractory BTC and PDAC, highlighting the promise of targeting PD-L1, TGF-β, and angiogenesis pathways simultaneously.

Evaluating the Economic Impact of Novel Oncology Drug Coverage Through Patient Assistance Programs.

Despite a universal public health care system, Canadian oncology patients often enroll in patient assistance programs (PAPs) to access oncology drugs that are awaiting funding decisions. Our multicenter study evaluated the pharmacoeconomic and clinical impact of PAPs for patients with cancer in British Columbia (BC). Eligible patients were diagnosed with cancer and enrolled in a PAP between January 2016 and December 2019 in three BC centers. Charts were reviewed for treatment details and survival data. For each drug indication, the hazard ratio from clinical trial data was multiplied by the median overall survival (mOS) or median progression-free survival (mPFS) of our cohort to estimate the mOS or mPFS if the drug was not received. Person life-years gained (PLYG) was the difference between the actual mOS or mPFS and the estimated mOS or mPFS if the drug was not received. Incremental cost-effectiveness ratios and drug costs were obtained from the Canadian Agency for Drugs and Technologies in Health. A total economic value of quality-adjusted life year (QALY) gained for each cohort was calculated and compared with the cost of drugs associated with the gain. Our cohort consisted of 1,025 patients who accessed 40 oncology drugs via PAP. The median time from Health Canada approval to provincial funding was 2.04 years. In the first PAP exposure group (N = 1,025), median PLYG was 0.38 years for OS and 0.80 years for PFS. The total estimated economic value of QALY gained was $83,068,819.32, with total drug costs of $97,026.661.44. PAPs were involved in covering up to $100 million in costs to bridge gaps between regulatory approval and public funding. Economic value and PLYG gained from PAPs are substantial.

Anlotinib plus chemotherapy as a first-line treatment for gastrointestinal cancer patients with unresectable liver metastases: a multicohort, multicenter, exploratory trial

This multicohort phase II trial (ALTER-G-001; NCT05262335) aimed to assess the efficacy of first-line anlotinib plus chemotherapy for gastrointestinal (GI) cancer patients with unresectable liver metastases. Eligible patients with colorectal cancer (Cohort A) or noncolorectal and nonesophageal GI cancer (Cohort C) received six cycles of anlotinib plus standard chemotherapeutic regimens followed by anlotinib plus metronomic capecitabine as a maintenance therapy. Liver metastasectomy can be performed when liver metastases are converted to resectable lesions. The primary outcome was the investigator-confirmed objective response rate (ORR) in the intention-to-treat population. Among the 47 patients in Cohort A, the ORR was 40.4% (95% CI 26.4–55.7), including 1 with a complete response (CR) and 18 who achieved a partial response (PR). The median progression-free survival (PFS) was 8.7 months (95% CI 7.3-NE), and the median overall survival (OS) was not reached. In Cohort C, 14 of 44 patients achieved a PR, with an ORR of 31.8% (95% CI 18.6–47.6). The PFS and OS were 5.8 months (95% CI 4.8–6.5) and 11.4 months (95% CI 5.8–19.3), respectively. The liver metastasectomy rate in patients with liver-limited disease was 22.7% (5/22) in Cohort A and 6.7% (2/30) in Cohort C. For pancreatic cancer patients, the ORR of the efficacy-evaluable population was 36.0% (9/25), and those with liver-limited metastasis had better survival. Moreover, no new safety concerns emerged. In conclusion, an anlotinib-based first-line regimen demonstrated promising antitumor activity among GI cancer patients with unresectable liver metastases and led to liver metastasectomy in selected patients.

Efficacy and Safety of Daratumumab in Intermediate/High-risk Smoldering Multiple Myeloma: Final Analysis of CENTAURUS.

Early intervention of smoldering multiple myeloma (SMM) may delay progression to multiple myeloma. Here, we present the final analysis of the phase 2 CENTAURUS study (NCT02316106). In total, 123 patients with intermediate/high-risk SMM were randomized to intravenous daratumumab 16 mg/kg following a Long intense (n = 41), Intermediate (n = 41), or Short intense (n = 41) dosing schedule. At a combined median follow-up of 85.2 months, in the Long intense, Intermediate, and Short intense arms complete response or better rates were 4.9%, 9.8%, and 0%; overall response rates were 58.5%, 53.7%, and 37.5%; progressive disease/death rates were 0.096, 0.102, and 0.109 (P <0.0001 for all arms); and median progression-free survival was not reached, 84.4, and 74.1 months, respectively. Median overall survival was not reached in any arm. Thirty-six patients in the Long intense or Intermediate arms continued daratumumab in an optional extension phase after completing 20 cycles of per protocol treatment. Median (range) duration of study treatment was 44.0 (1.0-91.6), 35.2 (1.9-90.6), and 1.6 (0.1-1.9) months in the Long intense, Intermediate, and Short intense arms, respectively. No new safety signals were observed. With extended follow-up (median, ~7 years), these data highlight the tolerability of daratumumab and support ongoing trials investigating daratumumab as an early intervention for SMM. ClinicalTrials.gov Identifier: NCT02316106.

Treatment adherence and effectiveness in patients treated with carfilzomib-based therapy combinations for relapsed/refractory multiple myeloma in Germany: interim results from the non-interventional CARO study

Therapy adherence can significantly influence the outcome of cancer patients. The prospective, non-interventional CARO study (NCT02970747) investigated adherence, effectiveness, and safety of carfilzomib in patients with relapsed/refractory multiple myeloma (RRMM) in the German real-world setting. In total, 359 patients were included at 69 sites. Data on carfilzomib combination regimens were evaluated for three treatment cohorts: carfilzomib with lenalidomide and dexamethasone (KRd), with dexamethasone only (Kd) or with daratumumab and dexamethasone (KdD). Encouragingly, patients maintained levels of treatment adherence ≥95% to carfilzomib across cohorts. The effectiveness outcomes of CARO were in line with previous data. Median PFS (95% CI) was 17.5 months (14.5, 24.7 [KRd]), 13.4 months (7.0, 18.1 [Kd]), and 15.6 months (9.9, NA [KdD]), respectively. Median OS was 38.9 months (31.5, 53.9 [KRd]), 24.2 months (17.3, 36.8 [Kd]), and not reached (KdD). Overall, the CARO study impressively demonstrates efficacy and safety of KRd, Kd, and KdD regimen in real-world.

DL-ICE as a bridge to allogeneic transplantation in relapsed/refractory PTCL: survival outcomes and prognostic factors

IntroductionPeripheral T-cell lymphomas (PTCLs) have poor outcomes in the relapsed/refractory (R/R) setting. In this study, we evaluated the efficacy of dexamethasone, L-asparaginase, ifosfamide, carboplatin, and etoposide (DL-ICE) chemotherapy followed by allogeneic hematopoietic stem cell transplantation (allo-HSCT) in patients with R/R PTCLs.MethodsWe retrospectively analyzed 80 adult patients with R/R PTCLs treated with DL-ICE chemotherapy between September 2009 and March 2023. Patients achieving complete or partial remission were eligible for consolidative allo-HSCT. Overall survival (OS) and progression-free survival (PFS) were evaluated.ResultsThe overall response rate to DL-ICE was 37.5%, with 30% achieving complete remission (CR). With a median follow-up of 96.4 months, the median OS and PFS were 8.9 and 3.8 months, respectively. Seventeen patients (21%) underwent allo-HSCT, including 11 with non-CR status. The 5-year OS was significantly higher in the allo-HSCT group compared to that in the group with chemotherapy alone (64.7% vs 18.3%, p &amp;lt;0.001). Multivariate analysis identified advanced stage, EBV viremia, and non-CR status as poor prognostic factors.DiscussionDL-ICE chemotherapy demonstrated modest activity in R/R PTCLs. Consolidation with allo-HSCT, even in patients who do not achieve CR, resulted in long-term survival in a subset of patients. Early consideration of allo-HSCT may improve outcomes for patients with R/R PTCLs.

Efficacy and safety of lenvatinib plus gefitinib in lenvatinib-resistant hepatocellular carcinomas: a prospective, single-arm exploratory trial

Lenvatinib, a multi-kinase inhibitor, has been approved as first-line treatment for advanced hepatocellular carcinoma (HCC), but its efficacy is limited. We have shown previously that lenvatinib and epidermal growth factor receptor tyrosine kinase inhibitor (EGFR-TKI) combination therapy overcomes lenvatinib resistance in HCC with high level of EGFR expression (EGFRhigh). We present here the results of a single-arm, open-label, exploratory study of lenvatinib plus the EGFR-TKI gefitinib for patients with HCC resistance to lenvatinib (NCT04642547; n = 30). Only patients with EGFRhigh HCC and progressive disease after lenvatinib treatment were recruited in the study. The most frequent adverse events of all grades were fatigue (27 patients; 90%), followed by rash (25 patients; 83.3%), diarrhea (24 patients; 80%), and anorexia (12 patients; 40%). Among 30 patients, 9 (30%) achieved a confirmed partial response and 14 (46.7%) had stable disease according to mRECIST criteria. Based on RECIST1.1, 5 (16.7%) achieved a confirmed partial response and 18 (60%) had stable disease. The estimated median progression free survival (PFS) and overall survival (OS) time were 4.4 months (95% CI: 2.5 to 5.9) and13.7 months (95% CI: 9.0 to NA), respectively. The objective response rate (ORR) of the patients in the present study compares very favorable to that seen for the two approved second line treatments for HCC (cabozantinib ORR of 4%; regorafenib ORR of 11%). Given that this combination was well-tolerated, a further clinical study of this combination is warranted.

Chemo-free salvage treatment outperforms traditional chemotherapy in advanced lines of relapsed/refractory subcutaneous panniculitis-like T-cell lymphoma

IntroductionSubcutaneous panniculitis-like T-cell lymphoma (SPTCL) is a rare subtype of non-Hodgkin lymphoma with a good prognosis, but the optimal treatment for relapsed/refractory (R/R) SPTCL has been rarely discussed.MethodsThis study aims to compare the efficacy of conventional chemotherapy and chemo-free immunomodulatory regimen for R/R SPTCL. We retrospectively reviewed the patients with first relapse or primary refractory SPTCL between September 1997 and October 2020.ResultsA total of 19 patients with R/R SPTCL with a median age of 34 were included. All patient received the first-line chemotherapy-based treatment with a median PFS of 1.8 months. In these patients, 16 received salvage second-line treatment with an ORR of 31.3% and a median TTNT of 3.0 months. 13 of these 16 patients received chemotherapy-based treatment, resulting in a median TTNT of 2.4 months. 2 of these 16 patients received allogeneic hematopoietic stem cell transplantation and achieved long term complete remission (CR). In third-line treatment, 7 patients received chemotherapy-based regimen and 6 received chemo-free regimen such as VRMP (bortezomib, lenadomide and methylprednisolone) regimen and CsA plus IFNα regimen. The median TTNT of chemotherapy and chemo-free group were 3.2 months and not reached, respectively.DiscussionChemo-free group had a better TTNT than chemotherapy group (p=0.007). The use of chemotherapy-free regimens for R/R SPTCL appears promising and warrants further validation.

Methods of nivolumab administration in advanced melanoma: A comparison of patients' clinical outcomes treated with flat dose or weight-adjusted dose, a multicenter observational study.

Nivolumab obtained approval in advanced melanoma (AM) with weight-adjusted dose (WAD) administration (3 mg/kg/2 weeks). In 2018, the dosage regimen was changed to flat dose (FD) administration (240 mg/2 weeks or 480 mg/4 weeks) based on a modeling study, without clinical data. AM patients have been prospectively included in the French national multicenter MelBase database since 2013. First-line patients treated with nivolumab monotherapy were included in the WAD or FD groups of this study. The primary end point was the incidence of grade ≥3 immune-related adverse events (irAEs). Secondary end points were incidence of any grade irAEs, and overall survival (OS) and progression-free survival (PFS). Inverse probability of treatment weighting was used to balance groups on their baseline characteristics. Between 2015 and 2022, 348 patients were included: 160 in the WAD and 188 in the FD groups. In the FD group, 45% and 27% of patients weighed <75 kg and >85 kg, respectively. Grade ≥3 and any grade irAEs rates were 13.1% versus 11.7% (p=.8) and 63.1% versus 67.0% (p=.5) in the WAD and FD groups, respectively. After weighting, median PFS was 3.1 and 3.7 months (hazard ratio [HR], 0.84; 95% confidence interval [CI], 0.65-1.07), and median OS was 24.8 and 37.0 months (HR, 0.74; 95% CI, 0.54-1.01) in the WAD and FD groups, respectively. There was no difference in the incidence of severe irAEs and in median PFS between AM patients treated by WAD or FD nivolumab. The median OS between patient groups did not reach statistical significance.

Zanubrutinib Versus Bendamustine and Rituximab in Patients With Treatment-Naïve Chronic Lymphocytic Leukemia/Small Lymphocytic Lymphoma: Median 5-Year Follow-Up of SEQUOIA.

Clinical trials frequently include multiple end points that mature at different times. The initial report, typically based on the primary end point, may be published when key planned co-primary or secondary analyses are not yet available. Clinical Trial Updates provide an opportunity to disseminate additional results from studies, published in JCO or elsewhere, for which the primary end point has already been reported.SEQUOIA (ClinicalTrials.gov identifier: NCT03336333) is a phase III, randomized, open-label trial that compared the oral Bruton tyrosine kinase inhibitor zanubrutinib to bendamustine plus rituximab (BR) in treatment-naïve patients with chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL). The initial prespecified analysis (median follow-up, 26.2 months) and subsequent analysis (43.7 months) found superior progression-free survival (PFS; the primary end point) in patients who received zanubrutinib compared with BR. At a median follow-up of 61.2 months, median PFS was not reached in zanubrutinib-treated patients; median PFS was 44.1 months in BR-treated patients (hazard ratio [HR], 0.29; one-sided P = .0001). Prolonged PFS was seen with zanubrutinib versus BR in patients with mutated immunoglobulin heavy-chain variable region (IGHV) genes (HR, 0.40; one-sided P = .0003) and unmutated IGHV genes (HR, 0.21 [95% CI, 0.14 to 0.33]; one-sided P < .0001). Median overall survival (OS) was not reached in either treatment arm; estimated 60-month OS rates were 85.8% and 85.0% in zanubrutinib- and BR-treated patients, respectively. No new safety signals were detected. Adverse events were as expected with zanubrutinib; rate of atrial fibrillation was 7.1%. At a median follow-up of 61.2 months, the results supported the initial SEQUOIA findings and suggested that zanubrutinib was a favorable treatment option for untreated patients with CLL/SLL.

Phase II study of MEK inhibitor trametinib alone and in combination with AKT inhibitor GSK2141795/uprosertib in patients with metastatic triple negative breast cancer.

While MEK inhibitors demonstrated activity in metastatic triple negative breast cancer (mTNBC) preclinical studies, preclinical, and clinical studies implicate rapid development of resistance limiting clinical benefit. The purpose of this study was to determine response rate for Trametinib alone and in combination with Uprosertib in patients with mTNBC previously treated with chemotherapy. This was an open-label, two-part, phase II, single-arm, multicenter study. Patients first received Trametinib monotherapy (2mg daily; Part I) then at progression transitioned to Trametinib (1.5mg) plus Uprosertib (50mg; Part II). Between October 2013 and January 2017, 37 patients were enrolled to Part I. Subsequently, 19 patients entered Part II. Of the 37 patients receiving Trametinib monotherapy, 2 patients achieved partial response (PR) for an ORR of 5.4% (2/37) and an additional 6/37 (16.2%) achieved stable disease (SD). The clinical benefit rate (PR+SD) for patients receiving monotherapy was 21.6% (8/37). Of the 19 patients in Part II, 3 patients achieved PR for an ORR to Part II of 15.8% (3/19) and an additional 3 achieved SD. Median progression-free survival (PFS) was 7.7 weeks for Part I and 7.8 weeks for Part II. Circulating tumor DNA (ctDNA) clearance at C2D1 of Trametinib monotherapy was associated with improved PFS and overall survival. In patients with mTNBC, Trametinib monotherapy demonstrated limited efficacy and addition of Uprosertib was associated with numerically greater objective responses but no difference in PFS. Translational analyses suggest ctDNA clearance as a potential early biomarker of response.

The efficacy and safety of lenvatinib plus pembrolizumab in vulnerable patients with metastatic or recurrent endometrial cancer: a single institution experience.

Effective management with second-line therapy with the lenvatinib + pembrolizumab regimen for patients with advanced endometrial cancer is necessary. This retrospective study enrolled patients with endometrial cancer treated with the lenvatinib + pembrolizumab regimen. We evaluated progression-free survival (PFS), overall survival (OS), safety for patients non-eligible for the KEYNOTE775 trial, aged ≥65years, or with ECOG performance status 1-2. Forty-five patients were analyzed: 21 (47%) were aged ˃ 65years, 16 (36%) had performance status 1-2, and 15 (33%) were non-eligible for KEYNOTE775 trial participation. Overall, the median PFS was 8.5months (95% confidence interval [CI] 4.6-12.4), and the median OS was 15.6months (95% CI 9.4-NA). Median PFS was significantly shorter in patients not eligible for KEYNOTE775 participation and with performance status 1-2. The median OS was significantly shorter in patients with performance status 1-2. Grade ˃3 adverse events (AEs) occurred in 78% of patients who received the lenvatinib + pembrolizumab regimen. AEs resulted in lenvatinib dose reductions in 35 patients (78%) and lenvatinib and pembrolizumab discontinuation in 3 (7%) and 5 (11%), respectively. The median time to the first lenvatinib dose reduction was 1.5 (0.92-2.3) months in all patients and was significantly shorter in patients aged >65years. The current regimen has favorable efficacy and manageable safety with appropriate dose reduction of lenvatinib in the real world. However, the efficacy may be inferior in patients with performance status 1 or 2, heavily treated patients, and those with organ dysfunction. The current treatment status should reflect real-world data relative to the medical environment and management.

Survival outcomes of Durvalumab in combination to cisplatin and gemcitabine in advanced biliary tract cancer: real world results from a single Italian institution.

The TOPAZ-1 phase III trial showed a survival benefit with durvalumab plus gemcitabine and cisplatin in patients with advanced biliary tract cancer (BTC). To understand this combination's real-world efficacy and tolerability, we conducted a retrospective analysis of its first-line treatment outcomes. We included patients with unresectable, locally advanced, or metastatic BTC treated with cisplatin, gemcitabine plus durvalumab. The primary endpoint was overall survival (OS). 33 patients were enrolled. Median OS was NR and median PFS was 7.6 months, after a median follow up of 13.5 months. The investigator-assessed overall response rate was 34.5 %, with stable disease in 53.0 % of patients. High baseline CEA levels were associated with poor survival. Any grade adverse events (AEs) occurred in 97 % of patients. Immune-related AEs (irAEs) occurred in 16 % (grade >2: 6 %). Presence of TP53 mutation was related to a worse OS, conversely the presence of ARID1A genomic alteration was related to a better PFS. A tendence toward a better OS was found for BRCAness patients which did not reach the statistical significance. On the other hand, BRCAness patients showed significantly higher PFS compared to no BRCAness patients Conclusion: This real-world analysis largely confirmed the TOPAZ-1 findings, supporting gemcitabine, cisplatin, and durvalumab as a first-line standard of care for patients with advanced BTC.

Real-world efficacy and safety of combined first-line treatment with PARP inhibitors and novel hormonal therapy in mCRPC patients with HRR gene mutations

ObjectiveThis study evaluated the real-world efficacy and safety of combining PARP inhibitors with novel hormonal therapy (NHT) as a first-line treatment in Chinese patients with metastatic castration-resistant prostate cancer (mCRPC) harboring homologous recombination repair (HRR) gene mutations.MethodsWe enrolled 41 mCRPC patients who received at least 1 month of combined treatment with PARP inhibitors and NHT. Patients were divided into two groups: Cohort A (mutations in BRCA1, BRCA2, or ATM genes) and Cohort B (mutations in other HRR genes). The primary endpoint was imaging-based progression-free survival (PFS), with secondary endpoints including objective response rate (ORR), disease control rate (DCR), overall survival (OS), PSA50 response, and adverse events (AEs). To ensure accurate research results and control confounding factors, we will employ multivariate Cox proportional hazards models to evaluate key variables affecting mCRPC patient survival outcomes.ResultsThis study enrolled 41 patients, 22 in Cohort A and 19 in Cohort B. The median PFS for all patients was 21.8 months, and the median OS had yet to be reached. The overall ORR was 48.8%, and the DCR was 61.0%. Specifically, the median PFS for Cohort A was 21.8 months compared to 14.5 months for Cohort B. The median OS had yet to be reached for either cohort. Regarding efficacy, 81.8% of patients in Cohort A and 73.7% in Cohort B achieved a PSA50 response. Imaging assessments showed ORRs of 54.6% for Cohort A and 42.1% for Cohort B, with DCRs of 72.7% and 47.4%, respectively. 85.4% of patients experienced grade 1 or 2 adverse events, and 51.2% encountered grade 3 or 4. In the multivariate Cox regression analysis focusing on PFS, the Gleason score was identified as a significant predictor (HR = 5.8, 95% CI: 1.65–20.2, p = 0.006).ConclusionCombined first-line treatment with PARP inhibitors and NHT is effective and well-tolerated in mCRPC patients with HRR gene mutations, particularly those with BRCA1, BRCA2, or ATM mutations. These findings underscore the potential of this therapeutic combination in managing mCRPC in the Chinese population, suggesting a favorable outcome for those with specific genetic backgrounds.

Undifferentiated uterine sarcoma : experience of a single center

ObjectivesTo investigate the clinicopathological characteristics and prognosis of patients with undifferentiated uterine sarcomas (UUS).Methods29 patients with UUS who were treated at our institution between 2001 and 2020 were analyzed.ResultsThe median age at diagnosis was 52 years (range: 26–70 years). The FIGO 2009 distribution by stage was as follows: stage I, 17 patients (58.6%); stage II, 5 patients (17.2%); stage III, 4 patients (13.8%); and stage IV, 3 patients (10.3%). For 28 patients who underwent surgical treatment, 27 patients (96.4%) underwent total/sub-radical/radical hysterectomy combined bilateral salpingo-oophorectomy, 17 (58.6%) pelvic lymphadenectomy, 7 (24.1%) para-aortic lymphadenectomy and 8 (28.6%) patients underwent omentectomy, as part of the initial surgical treatment. The median follow-up was 23.4 months (range: 4.5–200.2 months). 18 patients (62.1%) died during follow up, and 13 patients (72.2%, 13/18) died within 2 years after diagnosis. Median progression-free survival (mPFS) and overall survival (mOS) for the entire cohort were 15.5 and 27.4 months, respectively. 2-year and 5-year PFS were 40.3% and 26.9%. 2-year and 5-year OS were 54.0% and 36.5%. Stage-specific median PFS and OS were as follows: stage I-II—17.7 and 35.5 months, stage III-IV—6.0 and 6.7 months. Patients with recurrent UUS who underwent cytoreduction surgery associated with an improved overall survival (mOS: 52.9 vs. 17.9 months), but the difference was not statistically significant (P = 0.081).ConclusionsUUS are a rare group of tumors with an aggressive behavior and poor outcomes. A majority rapidly develops distant metastases despite surgical resection.

Efficacy and Safety of Erzhu Jiedu Decoction Granules in Treating Mid-advanced Hepatitis B Virus-Associated Primary Liver Cancer Patients with Pi (Spleen)-Deficiency and Dampness-Heat Syndrome.

To assess the efficacy and safety of Erzhu Jiedu Decoction (EZJDD) Granules in treating mid-advanced hepatitis B virus-associated primary liver cancer (HBV-PLC) patients with Pi (Spleen)-deficiency and dampness-heat syndrome. From January 2021 to June 2023, a cohort of 132 patients were enrolled and randomly assigned to a control group or a EZJDD group according to the random numbers, with 66 patients in each group. The patients in the control group received conventional treatment for 3 months, followed by a 3-month follow-up. In addition to the conventional treatment, patients in the EZJDD group were administered EZJDD Granules (10.9 g/pack, 2 packs twice per day) orally for same duration. Progression-free survival (PFS) as primary outcome was evaluated by Kaplan Meier method. Karnofsky performance status (KPS) scores were used to assess the quality of life in two groups before and after treatment, and survival rates were determined as well. The efficacy of Chinese medicine syndrome was calculated with Nimodipine method. Liver function, tumor indicators and T lymphocyte subsets were measured, respectively. Safety indicators were recorded and assessed. Of the 116 patients who completed the study, 57 were in the control group and 59 in the EZJDD group. The median PFS was 3.53 months (106 days) in the EZJDD group compared to 2.33 months (70 days) in the control group (P=0.005). Six-month survival rate was 52.63% (30/57) in the control group and 69.49% (41/59) in the EZJDD group (P=0.039). The median KPS score in the EZJDD group [70(63, 90)] was higher than that in the control group [70(60, 80)] (P=0.013). The total effective rate of CM syndrome was 52.63% (30/57) in the control group and 77.97% (46/59) in the EZJDD group (P=0.005). The levels of alpha fetoprotein, alpha fetoprotein-L3, alpha-L-fucosidase and protein induced by Vitamin K absence or antagonist- II in the EZJDD group increased less than the control group (P>0.05). CD8+ levels were decreased, while CD3+ and CD4+ levels, as well as CD4+/CD8+ ratio were significantly increased in the EZZJD group (P<0.05). No treatment-related adverse reactions were observed during the study. EZJDD Granules significantly prolonged the median PFS and improved 6-month survival rate in patients with mid-advanced HBV-PLC (Registration No. ChiCTR2200056922).

Real-world evidence of Trastuzumab Deruxtecan (T-DXd) Efficacy in HER2-expressing gynecological malignancies

Human epidermal growth factor receptor 2 (HER2) overexpression emerges as an attractive therapeutic target in gynecological malignancies. Recently, Trastuzumab-Deruxtecan (T-DXd) has shown substantial efficacy in HER2 overexpressing carcinomas, most prominently in ovarian, endometrial and cervical patients. We have examined the efficacy of T-DXd in patients with metastatic endometrial, ovarian and cervical malignancies that were treated in the Department of Clinical Therapeutics, Alexandra Hospital, School of Medicine, National and Kapodistrian University of Athens.MethodsPatients with gynecological malignancies with HER2 expression 2 + /3 + as assessed by immunohistochemistry (IHC) that were treated with T-DXd were retrospectively identified. Patients received T-DXd intravenously at a dose of 5.4 mg/kg every 3 weeks until disease progression or unacceptable toxicity.ResultsIn total, 10 patients treated with T-DXd for recurrent/metastatic disease were identified. Regarding histology, there were 5 patients with uterine neoplasms (serous carcinoma (n = 3), uterine carcinosarcoma (n = 1), uterine leiomyosarcoma (n = 1)), 1 patient with squamous cervical carcinoma and 4 patients with ovarian cancer (ovarian carcinosarcoma (n = 2), high-grade serous carcinoma (n = 1) and mucinous ovarian carcinoma (n = 1)). Median age was 65.4 years (25th-75th percentile, 58.1–75.2 years). 5 patients had HER2 expression 3 + by IHC and 5 patients had HER2 expression 2 + . Median number of previous lines of therapy was 4 (range 2–6), 2 patients with uterine serous carcinoma were pretreated with trastuzumab and 4 patients had already received immunotherapy. In the entire cohort median progression-free survival (PFS) was 5.4 months (95%CI 0.8–9.8 months). Regarding responses, 5 patients had partial response (including 2 patients that were pretreated with trastuzumab), 1 patient had stable disease at 12 weeks and 4 patients had disease progression at initial assessment. All patients but one that derived clinical benefit had HER2 3 + expression.DiscussionIn the real-world setting, T-DXd showed activity in a cohort of heavily pre-treated patients with HER2-expressing gynecological malignancies.

Survival Outcomes with Regorafenib and/or Trifluridine/Tipiracil Sequencing to Rechallenge with Third-Line Regimens in Metastatic Colorectal Cancer: A Multicenter Retrospective Real-World Subgroup Comparison from the ReTrITA Study

Background: There is ongoing discussion around the optimal course of treatment for metastatic colorectal cancer (mCRC) following the second line. Trifluridine/tipiracil (T) and regorafenib (R) have been the mainstay of therapy in this situation, as they both increased overall survival (OS) in comparison to a placebo. Despite the paucity of evidence, therapy rechallenge is also recognized as an option for practical use. In the third-line scenario of mCRC, we planned to investigate the survival outcomes using (T) and (R), both with and without prior rechallenge treatment. Materials and methods: Between 2012 and 2023, we examined the medical records of 1156 patients with refractory mCRC who were enrolled in the multicenter retrospective ReTrITA study. We then separated the patients into two cohorts based on the rechallenge therapy that was given before regorafenib and/or trifluridine/tipiracil at 17 Italian centres. Results: A total of 981 patients underwent T and/or R therapy, while 175 patients had therapy rechallenge before T and/or R. The median overall survival (mOS) for patients treated with T/R and R/T sequences in the rechallenge therapy cohort was 14.5 months and 17.6 months, respectively (p = 0.1955). A statistically significant survival benefit was observed in patients who received monotheraphy with R (mOS: 6 months) compared to the T group (mOS: 4.2 months) (p = 0.0332). In the same cohort, a median progression-free survival (mPFS) benefit was demonstrated in favour of the R/T group (11.3 months) vs. 9 months of the reverse sequence (p = 0.4004). In the no-rechallenge cohort, the mOS was statistically longer in the R/T sequence than in the T/R sequence (16.2 months vs. 12.3 months, respectively; p = 0.0014). In terms of the mPFS, we saw the same significant result for the adoption of R/T treatment (11.5 months vs. 8.4 months, respectively; p &lt; 0.0001). The two monotherapy groups did not reveal any significant differences. Conclusions: This study suggests that rechallenge therapy may improve survival rates in the third-line treatment of mCRC, particularly if it is administered before sequential R/T treatment. This could allow for the extension of mCRC treatment choices until prospective studies are finished or randomised trials are performed.
