RECIST 1.1, mRECIST, and Choi criteria for evaluating treatment response and survival outcomes in hepatocellular carcinoma patients treated with atezolizumab plus bevacizumab.

We aimed to compare the early responder rates, defined as complete or partial responders, using response evaluation criteria in solid tumors (RECIST) 1.1, modified RECIST (mRECIST), and Choi criteria in advanced HCC patients treated with atezolizumab-bevacizumab (atezo-bev), and to correlate them with progression-free survival (PFS) and overall survival (OS). This retrospective study included advanced HCC patients treated with ≥ 3 cycles of atezo-bev. Two reviewers assessed responses using RECIST 1.1, mRECIST, and Choi criteria at 1st follow-up imaging. Kaplan-Meier curves with log-rank tests evaluated and compared PFS and OS. Cox proportional hazard models identified survival outcome predictors. Kappa statistics assessed inter-reader agreement. We evaluated 77 patients (65 men; mean age, 62.8 ± 12.3 years). Choi's criteria revealed the highest early responders rate (53.2%), exceeding mRECIST (32.5-33.8%) and RECIST 1.1 (24.7-26.0%), with an excellent agreement in all criteria (κ, 0.85-0.95). Across criteria, a consistent number of patients progressed (23-26) and was associated with significantly poor OS (ps ≤ 0.049). Responders by any criteria showed longer PFS (ps ≤ 0.009), and 1-year OS (ps ≤ 0.01). Choi criteria linked to significantly better OS without landmark (p = 0.003), with 1-year OS rates at 76.9% for responders vs 38.1% for non-responders. Cox analysis identified responders by Choi criteria as a significant OS predictor. Choi criteria identified more early responders than RECIST 1.1 and mRECIST, significantly correlating with improved OS. Choi criteria could be considered as a formal response assessment criterion for the emerging atezo-bev systemic treatment. For atezo-bev treatment of advanced HCC, more comprehensive response criteria, such as Choi criteria, could be effective in identifying early responders and predicting survival outcomes along with RECIST 1.1 and mRECIST. Choi criteria identified a higher rate of early responders compared to mRECIST and RECIST1.1 following atezo-bev treatment. Responders by all criteria had longer PFS and 1-year OS, and only those by Choi criteria experienced longer OS without landmark time. Choi criteria, with RECIST 1.1 and mRECIST, is an effective response assessment tool for atezo-bev treatment.

Long-term survival outcomes of 'watch and wait' in patients with bronchus-associated lymphoid tissue lymphoma: a multicenter real-world data analysis in Korea.

Bronchus-associated lymphoid tissue (BALT) is a rare cause of extranodal marginal zone lymphoma (MZL). Although most patients with BALT lymphoma (BALToma) show an indolent clinical course and are monitored without treatment, there are limited real-world data on the long-term outcome of "watch-and-wait' strategy in comparison with other treatments.The survival outcomes of patients newly diagnosed with BALToma at three tertiary hospitals in Korea undergoing two treatment strategies were analyzed: group A, patients who were monitored without any treatment or received only radiotherapy after diagnosis; and group B, patients receiving any kind of systemic chemotherapy after diagnosis, regardless of their history of any local treatment such as surgery or radiotherapy.Of the 67 patients included in our analysis, the 10-year progression-free survival (PFS) and 10-year overall survival (OS) rates were 65.3% and 83.2%, respectively. The 10-year PFS rates for observation or localized treatment and systemic chemotherapy were 78.7% and 56.9%, respectively (p = 0.044). Ten-year OS rates for observation or localized treatment and systemic chemotherapy were 100% and 71.7%, respectively (p = 0.016). Multivariate analysis showed that bilateral lung (HR 2.462, p = 0.047) and extrapulmonary organ (HR 4.485, p = 0.004) involvement were the only significant factors associated with poor PFS. Prognostic factor analysis for OS did not yield significant results.Patients with BALToma show a favorable prognosis, suggesting that observation or localized therapy alone may be effective for patient management. However, patients with bilateral lung or extrapulmonary involvement may require careful monitoring for disease progression and more aggressive treatment approaches.

Postoperative radiotherapy with docetaxel versus cisplatin for high-risk oral squamous cell carcinoma: a randomized phase II trial with exploratory analysis of ITGB1 as a potential predictive biomarker

BackgroundOral squamous cell carcinoma (OSCC) causes significant mortality and morbidity worldwide. Surgical resection with adjuvant radiotherapy remains the standard treatment for locally advanced resectable OSCC. Results from landmark trials have established postoperative concurrent cisplatin-radiotherapy (Cis-RT) as the standard treatment for OSCC patients with high-risk pathologic features. However, cisplatin-related toxicity limits usage in clinical practice. Given the need for effective but less toxic alternatives, we previously conducted a single-arm trial showing favorable safety profiles and promising efficacy of concurrent docetaxel-radiotherapy (Doc-RT).MethodsIn this randomized phase 2 trial, we aimed to compare Doc-RT with the standard Cis-RT in postoperative OSCC patients. Eligible patients had AJCC stage III–IV resectable OSCC with high-risk pathologic features. Two hundred twenty-four patients were enrolled and randomly assigned to receive concurrent Doc-RT or Cis-RT. The primary endpoint was 2-year disease-free survival (DFS). Secondary endpoints included overall survival (OS), locoregional-free survival (LRFS), distant metastasis-free survival (DMFS), and adverse events (AEs). Integrin β1 (ITGB1) expression was analyzed as a biomarker for efficacy.ResultsAfter a median 28.8-month follow-up, 2-year DFS rates were 63.7% for Doc-RT arm and 56.1% for Cis-RT arm (p = 0.55). Meanwhile, Doc-RT demonstrated comparable efficacy to Cis-RT in OS, LRFS, and DMFS. Doc-RT resulted in fewer grade 3 or 4 hematological AEs. Low ITGB1 was associated with improved Doc-RT efficacy versus Cis-RT.ConclusionsThis randomized trial directly compared Doc-RT with Cis-RT for high-risk postoperative OSCC patients, with comparable efficacy and less toxicity. ITGB1 merits further validation as a predictive biomarker to identify OSCC patients most likely to benefit from Doc-RT. Findings indicate docetaxel may be considered as a concurrent chemoradiation option in this setting.Trial registrationwww.ClinicalTrials.gov. NCT02923258 (date of registration: October 4, 2016)

Inflammatory Bowel Disease as a Risk Factor for Complications and Revisions Following Lumbar Discectomy.

Retrospective cohort study. Patients with IBD are at an increased risk for postoperative complications following surgery. The goal of this study is to investigate if inflammatory bowel disease (IBD) is a risk factor for complications following lumbar discectomy. We identified IBD patients who underwent lumbar discectomy for lumbar disc herniation (LDH) and matched to them with controls without IBD in a1:5 ratio. We excluded patients with a history of spinal injury, cancer, infection, trauma, or surgery to remove the digestive tract. We used multivariate logistic regression analyses to compare postoperative outcomes, including 90-day complications, 90-day emergency department visits, and 90-day readmissions. In addition, 2-year re-discectomy rates and a 3-year lumbar fusion rate were compared between the cohorts. After applying the study criteria, we identified 6134 IBD patients with LDH for further analysis. With the exception of dura tears, patients with IBD had significantly higher rates of medical complications, incision-related complications, ED visits, and readmission rates compared to patients without IBD, especially for the 2-year and 3-year rates of disc recurrence and revision surgery. Patients with IBD who underwent lumbar discectomy are at a significantly higher rate of complications. Therefore, spine surgeons and other health care providers should be aware of this higher risk associated with IBD patients and properly treat the patients' IBD before surgery to lower these risks.

Knee fusion versus above knee amputation as two options to deal with knee periprosthetic joint infection.

Periprosthetic joint infection (PJI) poses a significant challenge in total knee arthroplasty (TKA), with recurrence rates as high as 14-28%, leading to substantial morbidity and treatment costs. When conventional treatments fail, knee fusion and above-the-knee amputation (AKA) emerge as alternative options. Existing literature offers conflicting views on the efficacy and impact of knee fusion versus AKA with varied outcomes and limitations. This retrospective national study spanning 2010-2022 investigates Knee Fusion and AKA as options for addressing Knee PJI. Utilizing PearlDiver Patient Records Database, procedural, and reimbursement data on over 100million individuals from all the US was evaluated. Readmission rates, costs, and complications of the mentioned procedures were assessed using ICD-9 and ICD-10 codes within a 90-day period and one-year post-operation. Statistical analyses, including chi-square tests and regression models, were conducted using integrated R software. The study reveals a substantial escalation (p < 0.0001) in the proportion of patients opting for AKA compared to arthrodesis. While age as a demographic factor showed no significant difference, arthrodesis patients exhibited lower comorbidity scores (3.6 ± 2.9 vs. 4.6 ± 3.4, p < 0.001). Arthrodesis correlated with higher 90-day thromboembolism rates (9.2% vs. 7.3%, p < 0.001), blood transfusion requirements (23.2% vs. 14.4%, p < 0.001), and acute renal failure incidence (p = 0.008) but demonstrated lower rates of urinary tract infections (p = 0.047) and cerebrovascular accidents (p < 0.001). At 1 year, arthrodesis was associated with higher infection rates (38.7% vs. 36.4%, p < 0.001). Arthrodesis patients had significant increased 90-day and 1-year readmission rates and hospitalization costs ($12,732 vs. $18,826, p < 0.001). We found higher rates of 1-year thromboembolism, infection, acute renal failure, and readmission in the arthrodesis group. AKA patients had more sepsis and cerebrovascular accidents. A patient-centered conversation is best for persistent infections and failed revision TKA. Considering the patient's quality of life, goals, and health status, this discussion should cover each procedure's risks and complications.

Sequence of Contact X-ray Brachytherapy (CXB) and External Beam Radiation (EBRT) in organ-preserving treatment for small rectal cancer

Background and purposeExternal Beam Radiotherapy (EBRT) followed by Contact X-ray Brachytherapy (CXB) and vice versa are viable alternatives to surgery for selected rectal cancer patients who have small tumours (≤3 cm). However, the optimal sequence of treatment needs to be established. We compared two approaches using Propensity Score (PS) matching and inverse probability treatment weighting (IPTW) analyses to investigate whether the sequence of treatment affected patient outcomes. Materials and methodsThis retrospective analysis (2008–2019) included patients with rectal adenocarcinoma (cT1-3,N0-1,M0, grade 1–2, size ≤ 3 cm) who received both EBRT and CXB, irrespective of treatment sequence. PS matching and IPTW were conducted to balance covariate standardised mean differences between groups. Oncological outcomes and rate of post-treatment rectal bleeding were assessed. ResultsFollowing PS matching and IPTW analyses from 251 eligible patients; 103 starting with EBRT (median follow-up: 37 [IQR:18–56] months) and 148 with CXB (median follow-up: 32 [IQR:16–54] months, a significant improvement in 3-year overall survival (77% vs 85%, p = 0.02, [HR:0.58 (95% CI:0.37–0.91)]) and a higher risk of post-treatment rectal bleeding (grade 1 (26%) and grade 2 (6%)) were found in patients who started with CXB (p = 0.08). No significant differences were observed in local regrowth (18% vs 12%, p = 0.47), distant relapse (10% vs 6%, p = 0.53), 3-year organ preservation rates (70% vs 75%, p = 0.20, [HR:0.66 (95% CI: 0.35–1.26)]), or disease-free survival (78% vs 82%, p = 0.17, [HR: 0.47 (95% CI: 0.16–1.38)]) ConclusionIn patients with rectal cancer (≤3 cm), commencing with CXB rather than EBRT, was associated with improved overall survival, but had a higher risk of G1/2 rectal bleeding. No statistically significant differences were observed in other oncological outcomes.

Multiple Single Cannulation Technique Improves the Outcomes of Arteriovenous Graft in Hemodialysis Patients: A Retrospective Study

To evaluate the effects of the multiple single cannulation technique (MUST) on the outcomes of arteriovenous graft (AVG). A retrospective study of AVG created between January 2018 and December 2021 at the First Affiliated Hospital of Zhengzhou University was conducted. The clinical data of patients and their follow-up data for venous access were analyzed. Subjects were divided into the MUST group or the non-MUST group according to whether MUST was used. The cumulative patency rate and complication incidence were compared between the two groups. Logistic regression was applied to analyze the influencing factors of applying MUST in AVG. The MUST group included 115 AVG and the non-MUST group, 122 AVG. The 1-year, 2-year, 3-year, and 4-year cumulative patency rates of the MUST group were 100%, 99.1%, 95.2%, 85.4%, and 73.2%, respectively, while those for the non-MUST group were 97.5%, 92.7%, 77.7%, 69.7%, and 50.0%, respectively, with the 2-year and 3-year patency rates showing significant difference (P=0.022, P=0.004). The standard intervention rate expressed in (median [interquartile range]) in the MUST group was significantly lower than that in the non-MUST group (0.46 [0.00, 0.94] vs. 0.97 [0.60, 1.59], Z=-5.808, P<0.001). A total of 24 (20.9%) AVG in the MUST group and 60 (49.2%) AVG in the non-MUST group had a standard intervention rate >1.0 per patient-year, with significant difference between the two groups. Three (2.6%) AVG in the MUST group and 7 (5.7%) AVG in the non-MUST group were complicated by aneurysm (χ 2=20.737, P<0.001). One (0.9%) AVG in the MUST group and 6 (4.9%) AVG in the non-MUST group had graft infection, with the difference between the groups showing no significance (P=0.121). Multivariate logistic regression showed that dialysis in the alliance facilities (odds ratio [OR]=2.713, 95% confidence interval [CI]: 1.698-4.336, P<0.001], and excellent follow-up [OR=2.189, 95% CI: 1.221-3.927, P=0.009] were the influencing factors of applying MUST in AVG. MUST improves the cumulative patency of AVG and decreases the intervention frequency and the incidence of aneurysm without increasing the risk of graft infection.

Stereotactic ablative radiotherapy for locally advanced non-small cell lung cancer: A systematic review and meta-analysis

IntroductionTo evaluate the feasibility, efficacy and safety of stereotactic ablative radiotherapy (SABR) to the primary tumor and lymph nodes in patients with locally advanced non-small cell lung cancer (LA-NSCLC) who are ineligible for or refused concomitant chemoradiation. Materials and MethodsIn accordance with the PRISMA and MOOSE guidelines, a systematic review with meta-analysis was conducted. The study included reports that assessed the outcomes of SABR treatment in patients with LA-NSCLC. Studies evaluating SBRT as a boost following primary radiotherapy were excluded. The primary outcomes measured were local control (LC) and overall survival (OS). The secondary endpoint was the incidence of severe toxicity (grades 3–5). A meta-regression analysis was performed to explore the relationship between LC, OS, and severe toxicity. The Biologically Effective Dose (BED) was analyzed as a continuous variable. Statistical significance was defined as a p-value < 0.05. ResultsA total of seven studies (3 prospective and 4 retrospective studies) involving 268 patients (SBRT to primary and lymph nodes) were included in the analysis. The pooled 1-year LC rate was 80 % (95 % CI: 63–94 %), and the factors significantly associated with LC were BEDGy10 (p = 0.005) and neoadjuvant chemotherapy (p = 0.005). The 1-year and 2-year OS rates were 74 % (95 % CI: 58–90 %) and 55 % (95 % CI: 34–76 %), respectively. Meta-regression analysis indicated a linear relationship between OS and LC, with a 0.7 % increase in OS for each 1 % improvement in LC (p = 0.005). The pooled rate of grade 3 acute toxicity was 5 % (95 % CI: 1–10 %), and the rate of grade 5 toxicity was 1.7 % (95 % CI: 0–3 %). ConclusionPromising results (LC and OS) with limited toxicity (feasibility) using SABR in LA-NSCLC warrant further research, emphasizing the need for larger, well-designed trials for further validation of the approach.

Clinical application of FIGO 2023 staging system of endometrial cancer in a Chinese cohort

ObjectiveThe International Federation of Gynecology and Obstetrics (FIGO) 2023 staging system for endometrial cancer (EC) was released with incorporating histology, lympho-vascular space invasion, and molecular classification together. Our objective is to further explore the clinical utility and prognostic significance of the 2023 FIGO staging system in China.MethodsA retrospective analysis was conducted for patients who received standard surgeries and underwent genetic testing using multigene next-generation sequencing (NGS) panels between December 2018 and December 2023 at Fudan University Shanghai Cancer Center, Shanghai, China. The genomic and clinical data of all patients were analyzed, and stages were determined by both the 2009 and 2023 FIGO staging systems. Kaplan–Meier estimators and Cox proportional hazards models were used for survival analysis.ResultsA total of 547 patients were enrolled in the study. After the restaged by the FIGO 2023 staging system, stage shifts occurred in 147/547 (26.9%) patients. In patients with early stages in FIGO 2009 (stage I-II), 63 cases were rearranged to IAmPOLEmut and 53 cases to IICmp53abn due to the molecular classification of POLEmut and p53abn. Altogether 345 cases were in stage I, 107 cases in stage II, 69 cases in stage III, and 26 cases in stage IV according to the FIGO 2023 staging criteria. For stage I diseases, the 3-year PFS rate was 92.7% and 95.3% in 2009 and 2023 FIGO staging systems, respectively. The 3-year PFS of stage II in 2023 FIGO was lower than that of FIGO 2009 (3-year PFS: 85.0% versus 90.9%), especially in substage IIC and IICmp53abn. Three cases (12%) of stage IIIA in FIGO 2009 were shifted to stage IA3 FIGO 2023, with 3-year PFS rates of 90.9% versus 100%, respectively. In NGS analysis, the most prevalent gene alterations were observed in PTEN and PIK3CA.ConclusionThe FIGO 2023 staging system was proved to be a good predictor of survival for EC patients with enhanced precision compared to FIGO 2009. Predominant stage shifts were observed in early-stage diseases. Distinct gene alterations of different subtypes may help to explore more accurate target therapies.

Outcomes in Critically Ill Allogeneic Hematopoietic Stem-Cell Transplantation Recipients.

Rationale: Allogeneic hematopoietic stem-cell transplantation (Allo-HSCT) recipients are still believed to be poor candidates for ICU management. Methods: We investigated outcomes and determinants of mortality in a large multicenter retrospective cohort of Allo-HSCT patients admitted between January 1, 2015, and December 31, 2020, to 14 French ICUs. The primary endpoint was 90-day mortality. Measurements and Main Results: In total, 1,164 patients were admitted throughout the study period. At the time of ICU admission, 765 (66%) patients presented with multiple organ dysfunction, including acute respiratory failure in 40% (n = 461). The median sepsis-related organ failure assessment score was 6 (interquartile range, 4-8). Invasive mechanical ventilation, renal replacement therapy, and vasopressors were required in 438 (38%), 221 (19%), and 468 (41%) patients, respectively. ICU mortality was 26% (302 deaths). Ninety-day, 1-year, and 3-year mortality rates were 48%, 63%, and 70%, respectively. By multivariable analysis, age > 56 years (odds ratio [OR], 2.0 [95% confidence interval (CI), 1.53-2.60]; P < 0.001), time from Allo-HSCT to ICU admission between 30 and 90 days (OR, 1.68 [95% CI, 1.17-2.40]; P = 0.005), corticosteroid-refractory acute graft-versus-host disease (OR, 1.63 [95% CI, 1.38-1.93]; P < 0.001), need for vasopressors (OR, 1.9 [95% CI, 1.42-2.55]; P < 0.001), and mechanical ventilation (OR, 3.1 [95% CI, 2.29-4.18]; P < 0.001) were independently associated with 90-day mortality. In patients requiring mechanical ventilation, mortality rates ranged from 39% (no other risk factors for mortality) to 100% (four associated risk factors for mortality). Conclusions: Most critically ill Allo-HSCT recipients survive their ICU stays, including those requiring mechanical ventilation, with an overall 90-day survival rate reaching 51.8%. A careful assessment of goals of care is required in patients with two or more risk factors for mortality.

Treatment outcomes of surgery followed by short-course every other day radiotherapy in keloid

BackgroundPostoperative radiotherapy can significantly reduce keloid recurrence. However, consensus on the optimal radiotherapy dose and treatment schedule remains elusive. This study aims to evaluate the effectiveness of surgery followed by a short-course of radiotherapy administered every other day for keloid treatment.Materials/MethodsWe conducted a retrospective analysis of 498 patients with keloids treated at our institution between January 2010 and December 2017. All patients underwent electron beam irradiation at a dose of 16 Gy, delivered in four fractions every other day, starting within 24 h post-surgery. The primary endpoint of the study was the local control rate.ResultsA total of 130 (26.5%) keloids recurred after a median follow-up of 68.1months (42.6-129.9 months). The local control rates at 1 year, 3 years and 5 years for all patients were 89.5%, 82.5% and 81%, respectively. The highest recurrence rate was observed in keloids located in the chest region (50.8%), followed by the suprapubic (47.8%), head and neck (38.8%), limbs (33.3%) and ear (14%). Both multivariate and univariate analyses identified the presence of pain and or pruritus as an independently prognostic factor for keloid recurrence (p<0.0001). The local control rates at 1-year, 3-years and 5-years for patients with or without symptom of pain or pruritus were 45% vs. 98.8%, 12.5% vs. 95.9%, and 8.8% vs. 95%, respectively (HR:37.829, 95%CI: 24.385–58.686, p<0.001). In the ear keloid subgroup, the 1-year, 3-year and 5-year local control rates for patients with pruritus were significantly lower than those without pain or pruritus (60.0% vs. 97.9%, 26.7% vs. 94.7%, 26.7% vs. 94.3%, HR:30.209, 95% CI:14.793–61.69, p<0.001). The same results were found in other location(p<0.001). During treatment and follow-up, two patients experienced infections, and one patient developed a cutaneous fibroblastoma.ConclusionThis study suggests that a combination of surgery followed by short-course, every-other-day radiotherapy can yield satisfactory local control rates for keloids. Pain and or pruritus symptom was an independently prognostic factors for recurrence of keloid. To further validate these results, a prospective randomized controlled trial is recommended.

Quality of life and survival analyses of breast cancer cases treated with integrated traditional Chinese and Western medicine.

Breast cancer (BC) is the second leading cause of tumor-related mortality after lung cancer. Chemotherapy resistance remains a major challenge to progress in BC treatment, warranting further exploration of feasible and effective alternative therapies. To analyzed the quality of life (QoL) and survival of patients with BC treated with integrated traditional Chinese and Western medicine (TCM-WM). This study included 226 patients with BC admitted to the First Affiliated Hospital of Guangxi University of Traditional Chinese Medicine between February 2018 and February 2023, including 100 who received conventional Western medicine treatment (control group) and 126 who received TCM-WM treatment (research group). The total effective rate, side effects (alopecia, nausea and vomiting, hepatorenal toxicity, and myelosuppression), QoL assessed using the European Organization for Research and Treatment of Cancer Core Quality of Life Questionnaire (EORTC QLQ-C30), 1-year overall survival (OS), recurrence and metastasis rates, and serum inflammatory factors [interleukin (IL)-6, IL-10, and tumor necrosis factor alpha] were comparatively analyzed. The research group showed statistically better overall efficacy, EORTC QoL-C30 scores, and 1-year OS than the control group, with markedly lower side effects and 1-year recurrence and metastasis rates. Moreover, the posttreatment levels of serum inflammatory in the research group were significantly lower than the baseline and those in the control group. Overall, TCM-WM demonstrated significantly improved therapeutic efficacy while ensuring drug safety in BC, which not only improved patients' QoL and prolonged survival, but also significantly inhibited the inflammatory response.

PSA Levels and Mortality in Prostate Cancer Patients

IntroductionProstate cancer (PC) is the second most common cancer among men around the world. Several smaller studies have explored the relationship between elevated PSA and mortality, but results have been conflicting. Additionally, studies have shown that Black men are more likely to be diagnosed with PC at late-stages and may have a twofold increase in mortality risk. This study aims to evaluate the relationship between PSA levels and mortality in patients with PC and differences between Black versus White patients. MethodsIn this retrospective study, the TriNetX database, was used to extract de-identified EMRs of 198,083 patients. Patients were included if they were diagnosed with PC and had obtained a PSA level (measured in ng/mL) within 6 months prior to diagnosis. Cohorts were separated into 7 groups based on intervals of PSA, ranging from < 2 to ≥ 500 and compared to a control cohort with a PSA of 4 to 20 for differing 2-year mortality rates. A subgroup analysis was performed to compare mortality differences between Black and White patients. A posthoc analysis evaluated 5- and 10-year mortality amongst all patients with PC. ResultsAfter propensity matching, mortality risk was significantly lower for patients with PSA < 2 (5.9% vs. 7.5%; RR 0.784; P < .001) when compared to the control cohort. Mortality was significantly higher for all other subsequent PSA intervals > 20, with the lowest risk ratios at PSA 20-100 (24.1% vs. 10.0%; RR 2.419; P < .001) and highest at PSA 200 to 500 (50.4% vs. 10.8%; RR 4.673; P < .001). The sub-group analysis showed that when compared to White patients, Black patients with PSA < 20 had similar mortalities, but had significantly lower 2-year mortality rates at PSA levels ≥ 20. The posthoc analysis of PSA levels and 5- and 10-year mortality of all patients with PC showed similar trends to the 2-year outcomes. ConclusionThis study found that prostate cancer patients with significantly elevated PSA levels have a greater mortality, and Black patients have lower 2-year mortality rates than their White counterparts when matched for PSA levels greater than 20.

Estimated impact of guidelines-based initiation of dual antihypertensive therapy on long-term cardiovascular outcomes in 1.1 million individuals.

Guidelines recommend initiation of dual combination antihypertensive therapy, preferably single-pill combination (SPC), in most patients with hypertension. Evidence on narrowing gaps in clinical practice relative to guidelines is limited. Monte Carlo simulation was applied to 1.1 million patients qualifying for dual combination therapy from a previously conducted retrospective analysis of clinical practice, hospital statistics, and national statistics in the UK. We provide 10-year Kaplan-Meier event rates for the primary endpoint representing a composite of nonfatal myocardial infarction, nonfatal stroke (ischemic or hemorrhagic), nonfatal heart failure hospitalization or cardiovascular death. Cox model results from a previously conducted study were utilized to estimate baseline risk, together with evidence on risk reduction from the Blood Pressure Lowering Treatment Trialists' Collaboration (BPLTTC) meta-analysis and published evidence on BP-lowering efficacy of antihypertensive therapies. In the overall population, estimated 10-year event rates for the primary endpoint in patients with 100% persistence in monotherapy were 17.0% for irbesartan (I) and 17.6% for ramipril (R). These rates were only modestly better than that observed in clinical practice (17.8%). In patients with 100% persistence in dual therapy, estimated event rates were 13.6% for combinations of Irbesartan+Amlodipine (ARR=8.7% compared to untreated) and 14.3% for Ramipril+Amlodipine (ARR=8.0% compared to untreated). The absolute risk of the primary endpoint was reduced by 15.9% in patients with ASCVD and 6.6% in those without ASCVD. Similarly, the absolute risk was reduced by 11.7% in diabetics and 7.8% in those without diabetes. This study represents the first to investigate guidelines-based treatment in hypertensive patients and demonstrates the opportunity for considerable risk reduction by ensuring recommended dual therapy in clinical practice, particularly in the form of SPC with high persistence, relative to no treatment or monotherapy.

Long-term outcomes of laparoscopic versus open distal gastrectomy for patients with advanced gastric cancer in North China: a multicenter randomized controlled trial

BackgroundLaparoscopic distal gastrectomy (LDG) has become a common procedure for treating advanced gastric cancer (AGC) in China. However, there is uncertainty regarding its oncological outcomes compared to open distal gastrectomy (ODG). This study aims to compare the 3-year disease-free survival (DFS) rates among patients who underwent surgery for AGC in northern China.MethodsA multicenter, non-inferiority, open-label, parallel, randomized clinical trial was conducted to evaluate patients with AGC who were eligible for distal gastrectomy at five tertiary hospitals in North China. In this trial, patients were randomly assigned preoperatively to receive either LDG or ODG in a 1:1 allocation ratio. The primary endpoint was postoperative morbidity and mortality within 30 days and the secondary endpoint was the 3-year DFS rate. This trial has been registered at ClinicalTrials.gov (Identifier: NCT02464215).ResultsA total of 446 patients were randomly allocated to LDG (n = 223) or ODG group (n = 223) between March 2014 and August 2017. After screening, a total of 214 patients underwent the open surgical approach, while 216 patients underwent laparoscopic surgery. The 3-year DFS rate was 85.9% for the LDG group and 84.72% for the ODG group, with no significant statistical difference (Hazard ratio 1.12; 95% CI 0.68–1.84, P = 0.65). Body mass index (BMI) < 25 kg/m2, advanced pathologic T4, and pathologic N2-3 category were confirmed as independent risk factors for DFS in the Cox regression.ConclusionsIn comparison to ODG, LDG with D2 lymphadenectomy yielded similar outcomes in terms of 3-year DFS rates among patients diagnosed with AGC.

Oncologic Outcomes of Patients with Early-Stage Cervical Cancer after Minimally Invasive Radical Hysterectomy and Sentinel Lymph Node Biopsy.

Background: The sentinel lymph node is the first node that cancer cells reach when migrating from the primary site. However, oncological outcomes after sentinel lymph node biopsy (SNB) have not been reported for cervical cancer. In this study, oncological outcomes were compared between patients receiving SNB and pelvic lymphadenectomy (PLD) for early-stage cervical cancer. Methods: One hundred and four patients with clinical stage 1A2, 1B1, and 2A1 cervical cancer were included in this study. All patients underwent laparoscopic or robot-assisted radical hysterectomy with SNB or PLD. Fifty-two patients with tumors ≤2 cm underwent SNB. Disease-free survival (DFS) and overall survival (OS) were compared between the groups. Results: The median (interquartile range) tumor size was 12 (7-20) mm in the SNB group and 20 (13-25) mm in the PLD group. Lymph node metastasis occurred in one patient in the SNB group and in nine patients in the PLD group. The median follow-up periods were 42 (24-60) and 82 (19-101) months in the SNB group and PLD group, respectively. The 3-year DFS rates were 100% in SNB and 91.5% in PLD. The 3-year OS was 100% in both groups. Conclusions: SNB was sufficient in cervical cancer patients with tumors ≤2 cm, suggesting that PLD might not be necessary for these patients.

Efficacy of PD-1 inhibitors combined with nab-paclitaxel and cisplatin in the neoadjuvant treatment of locally advanced hypopharyngeal squamous cell carcinoma

Objective: To assess the efficacy of neoadjuvant treatment with PD-1 (programmed cell death protein 1) inhibitors combined with paclitaxel (albumin-conjugated) and cisplatin (TP regimen) for locally advanced hypopharyngeal squamous cell carcinoma and laryngeal organ function preservation. Methods: Data of 53 patients, including 51 males and 2 females, aged 38-70 years old, who were diagnosed with locally advanced hypopharyngeal squamous carcinoma confirmed by histology and enhanced CT at the Cancer Prevention and Control Center of Sun Yat-sen University during the initial treatment from January 1, 2019 to January 15, 2023, were retrospectively analyzed. All patients received neoadjuvant therapy with PD-1 inhibitors combined with albumin-bound paclitaxel (260 mg/m2) and cisplatin (60 mg/m2) for 3 to 4 cycles. The main outcome measures were larynx dysfunction-free survival (LDFS), overall survival (OS), and progression-free survival (PFS). Survival curves were plotted using the Kaplan-Meier method, and Cox multifactorial analysis was further performed if Cox univariate analysis was statistically significant. Results: The overall efficiency was 90.6% (48/53). The 1-year and 2-year LDFS rates were 83.8% (95%CI: 74.0% to 94.8%) and 50.3% (95%CI: 22.1% to 91.6%), the 1-year and 2-year OS rates were 95.2% (95%CI: 88.9% to 100.0%) and 58.2% (95%CI: 25.6% to 81.8%), and the 1-year and 2-year PFS rates were 83.9% (95%CI: 74.2% to 94.9%) and 53.5% (95%CI: 32.1% to 89.1%). Adverse events associated with the neoadjuvant therapy were mainly myelosuppression (45.3%), gastrointestinal reactions (37.7%) and hypothyroidism (20.8%). Conclusion: The neoadjuvant treatment of locally advanced hypopharyngeal squamous cell carcinoma using PD-1 inhibitors combined with paclitaxel and cisplatin can provide with a higher survival rate with a improved laryngeal organ function preservation rate.

A retrospective study on the impact of radiotherapy on the survival outcomes of small cell lung cancer patients based on the SEER database

Small cell lung cancer (SCLC) patients exhibit significant heterogeneity in tumor burden, physical condition, and responses to initial treatment. This diversity in treatment responses can result in varying treatment outcomes. The primary objective of this study was to explore the patient demographics associated with improved survival outcomes through radiotherapy. Based on the SEER database, we identified 42,824 SCLC patients enrolled between 2004 and 2015. These patients were stratified into radiotherapy (n = 20,360) and non-radiotherapy groups (n = 22,464). We controlled for confounding factors using propensity score matching (PSM) analysis. Subsequently, Kaplan–Meier (KM) analysis was employed to evaluate the impact of radiotherapy on patients’ overall survival (OS) and cancer-specific survival (CSS). Cancer-specific mortality was further analyzed using competitive risk models. Cox analysis was also conducted to examine additional variables potentially affecting the survival of SCLC patients. We identified a total of 42,824 eligible patients, and following PSM, 13,329 patients were successfully matched in both the radiotherapy and non-radiotherapy groups. The KM analysis showed that the median OS was 9 months in the radiotherapy group and 6 months in the non-radiotherapy group. The median CSS was 10 months in the radiotherapy group and 7 months in the non-radiotherapy group. The 5-year OS and 10-year OS rates were 6.2% versus 1.6% in the radiotherapy group and 2.6% versus 0.8% in the non-radiotherapy group (P < 0.001). Competitive risk analysis showed that cancer-specific mortality was significantly higher in the non-radiotherapy group than in the radiotherapy group (P < 0.001). Multivariate Cox analysis showed that the radiotherapy group (relative non-radiotherapy group) showed a significant positive effect on survival outcomes (OS: HR 0.658 95% CI [0.642, 0.675] P < 0.001; CSS: HR 0.662 95% CI [0.645, 0.679], P < 0.001). In addition, age, gender, race, primary tumor site, T stage, N stage, M stage, chemotherapy, and surgery were also considered as important predictors of SCLC outcome. The results of the subgroup analysis showed that the radiotherapy group showed a significant survival advantage regardless of age, sex, race, primary tumor site, M stage, chemotherapy, and surgery (P < 0.001). Radiotherapy may improve both OS and CSS in SCLC patients. Patients with SCLC may benefit from radiotherapy regardless of age, sex, race, primary tumor site, M stage, chemotherapy, and surgery.

Multistaged Stereotactic Radiosurgery for Complex Large Lobar Arteriovenous Malformations: A Case Series.

Although stereotactic radiosurgery (SRS) has well defined outcomes in the management of smaller-volume arteriovenous malformations (AVM), this report evaluates the outcomes when SRS is used for large-volume (≥10 cc) lobar AVMs. Between 1990 and 2022, a cohort of 1325 patients underwent Leksell Gamma Knife SRS for brain AVMs. Among these, 40 patients (25 women; median age: 37 years) with large lobar AVMs underwent volume-staged SRS followed by additional SRS procedures if needed (2-5 procedures). The patients presented with diverse AVM locations and Spetzler-Martin Grades. Before SRS, 16 patients underwent a total of 43 embolization procedures. Over a median follow-up of 73 months, 20 patients achieved AVM obliteration. The 3, 5, and 10-year obliteration rates were 9.3%, 15.3%, and 53.3%, respectively. During the latency interval between the first SRS procedure and the last follow-up, 11 patients had intracerebral hemorrhages (ICH) and 6 developed new neurological deficits unrelated to ICH. The postoperative hemorrhage risk after the first SRS was 13.8% at 3 years, 16.6% at 5 years, and 36.2% at 10 years. No hemorrhagic event was documented after confirmed obliteration. Compared with the modified Rankin Scale (mRS) scores before SRS, the mRS improved or remained stable in 28 patients. Nine patients died during the observation interval. Five were related to ICH. These outcomes underscore both the potential effectiveness and the limitations of multistage SRS procedures for complex high-risk large volume AVMs in critical brain lobar locations. Most patients retained either stable or improved long-term mRS scores. During the latency interval from the first SRS until obliteration, achieved after two or more procedures, the risk of hemorrhage and treatment-related complications persists.

Prognosis of Pneumonia in Head and Neck Squamous Cell Carcinoma Patients Who Received Concurrent Chemoradiotherapy.

Concurrent chemoradiotherapy (CCRT) is the standard treatment for patients with locally advanced squamous cell carcinoma of the head and neck (HNSCC). Pneumonia is a significant complication in these patients. This study aims to identify pneumonia risk factors and their impact on survival in HNSCC patients undergoing CCRT. Data from the Chang Gung Research Database (CGRD) were retrospectively reviewed for patients treated between January 2007 and December 2019. Of 6959 patients, 1601 (23.01%) developed pneumonia, resulting in a median overall survival (OS) of 1.2 years compared to 4.9 years in the non-pneumonia group (p < 0.001). The pneumonia group included older patients with advanced tumors, more patients with diabetes mellitus (DM), more patients with invasive procedures, longer chemotherapy and radiotherapy durations, and lower body weight. The 2-year, 5-year, and 10-year OS rates were significantly lower in the pneumonia group. Multivariate analysis identified alcohol consumption, DM, gastrostomy, nasogastric tube use, longer chemotherapy, and a 2-week radiotherapy delay as independent risk factors. Understanding these risks can lead to early interventions to prevent severe pneumonia-related complications. A better understanding of the risks of pneumonia enables early and aggressive interventions to prevent severe complications.
