Objective:To evaluate the efficacy and safety of radiotherapy combined with sintilimab and bevacizumab (anti-angiogenic agent) in patients with unresectable advanced hepatocellular carcinoma (HCC).Methods:Clinical data of 80 patients with unresectable advanced HCC admitted to Shanghai Mengchao Cancer Hospital from January 2021 to September 2023 were retrospectively analyzed. All patients were divided into two groups based on treatment regimens: the systemic therapy group ( n=41) receiving sintilimab combined with bevacizumab, and combined radiotherapy group ( n=39) receiving radiotherapy plus sintilimab and bevacizumab. Efficacy was evaluated using the response evaluation criteria in solid tumors (RECIST) 1.1 version and modified RECIST for HCC. Treatment-related adverse events (TRAE) were assessed by the common terminology criteria for adverse events (CTCAE) 4.03 version. The primary endpoints were progression-free survival (PFS) and overall survival (OS). Secondary endpoints included objective response rate (ORR), disease control rate (DCR), and TRAE. Independent sample t-test was used for normally distributed quantitative data, and Chi-square test for qualitative data. Survival analysis was performed via Kaplan-Meier method and log-rank test. Univariate and multivariate Cox regression models were applied to analyze prognostic factors. Results:In terms of efficacy, no patient obtained complete response (CR) in the systemic therapy group, while 2 cases achieved CR in the combined radiotherapy group. The ORR was 22% (9/41) in the systemic therapy group and 59% (23/39) in the combined radiotherapy group ( P=0.001). The DCR was 85% (35/41) and 97% (38/39) in the two groups ( P=0.130), with the incidence of progressive disease of 15% (6/41) and 3% (1/39) ( P=0.130), respectively. The median PFS was 8.0 months (95% CI=6.8-9.2 months) in the combined radiotherapy group and 4.4 months (95% CI=4.1-4.7 months) in the systemic therapy group ( P=0.002). The median OS was 19.0 months (95% CI=15.5-22.5 months) in the combined radiotherapy group and 12.5 months (95% CI=9.4-15.6 months) in the systemic therapy group ( P=0.006). Radiotherapy was an independent protective factor for both PFS ( HR=0.474, 95% CI=0.289-0.778, P=0.003) and OS ( HR=0.403, 95% CI=0.218-0.744, P=0.004). The number of tumors >3 was an independent risk factor for both PFS ( HR=2.658, 95% CI=1.485-4.755, P=0.001) and OS ( HR=3.245, 95% CI=1.773-5.939, P=0.001). There was no significant difference in TRAE between two groups ( P > 0.05). Conclusions:Radiotherapy combined with sintilimab and bevacizumab shows high efficacy and acceptable safety in patients with unresectable advanced HCC.

Objective To investigate the clinical efficacy of laparoscopic-assisted linea alba reconstruction for postpartum diastasis recti.Methods The retrospective cross-sectional study was conducted.The clinical data of 14 patients with postpartum diastasis recti who were admitted to Ruijin Hospital of Shanghai Jiaotong University School of Medicine between June 2016 and June 2018 were collected.Patients underwent laparoscopic-assisted linea alba reconstruction.Observation indicators:(1) intra-and post-operative recovery situations;(2) follow-up.Follow-up using outpatient examination and telephone interview was performed to detect postoperative long-term complications,diastasis recti and umbilical hernia recurrence up to September 2018.Measurement data with normal distribution were represented as (x)±s and measurement data with skewed distribution were described as M (P25,P75).Results (1) Intra-and post-operative situations:14 patients underwent successful laparoscopic-assisted linea alba reconstruction and 8 complicated with umbilical hernia area of (6± 3) cm2 were sutured and closed.The mesh area,operation time,visual analogue score for pain at the first day after operation,time of postoperative drainage-tube removal and duration of postoperative hospital stay were respectively (214±26) cm2,(74 ± 14) minutes,3.7 ± 0.6,(3.3 ± 0.7) days and (4.1 ± 1.2) days.No patient required administration of analgesics and had postoperative complication.(2) Follow-up:14 patients were followed up for 17 months (5 months,21 months).During the follow-up,1 patient returned visit at postoperative day 10 due to surgical incision drainage and cured after dressing change.The other patients had no complications,without diastasis recti and umbilical hernia recurrence.Conclusion Laparoscopic-assisted linea alba reconstruction for postpartum diastasis recti is safe and effective.
