Large randomized clinical trials and prior meta-analyses indicate that second-generation BCR-ABL tyrosine kinase inhibitors (TKIs) improve surrogate biomarkers in patients with chronic myeloid leukemia (CML) without providing survival benefits. The objective is to evaluate the long-term efficacy and the occurrence of vascular occlusion with second-generation BCR-ABL TKIs compared with imatinib in patients with CML. Three scientific databases, a clinical registry and abstracts from congress were searched to identify all randomized controlled trials that compared a second-generation BCR-ABL TKI to imatinib in patients with CML. Outcomes extracted were overall survival, major molecular response and complete cytogenetic response, arterial occlusive events and venous thromboembolism. These data were synthesized by odds ratios using a fixed-effect model. This meta-analysis included 4659 participants from 14 trials. Second-generation BCR-ABL TKIs did not improve overall survival compared with imatinib, even at longer follow-up (OR, 1.17 (95% CI, 0.91–1.52)). They improved surrogate biomarkers at 12 and 24 months but increased the risk of arterial occlusion (ORPETO, 2.81 (95% CI, 2.11–3.73)). The long-term benefits of second-generation TKIs are restricted to surrogate outcomes and do not translate into prolonged survival compared to imatinib. Given the long-term use, frontline therapy should be chosen carefully, with special attention to the patients’ quality of life and cardiovascular risks.

Background: Treatment options for advanced gastric esophageal cancer are quite limited. Chemotherapy is unavoidable at certain stages, and research on targeted therapies has mostly failed. The advent of immunotherapy has brought hope for the treatment of advanced gastric esophageal cancer. The aim of the study was to analyze the safety of anti-PD-1/PD-L1 immunotherapy and the long-term survival of patients who were diagnosed as gastric esophageal cancer and received anti-PD-1/PD-L1 immunotherapy. Method: Studies on anti-PD-1/PD-L1 immunotherapy of advanced gastric esophageal cancer published before February 1, 2020 were searched online. The survival (e.g. 6-month overall survival, 12-month overall survival (OS), progression-free survival (PFS), objective response rates (ORR)) and adverse effects of immunotherapy were compared to that of control therapy (physician’s choice of therapy). Results: After screening 185 studies, 4 comparative cohort studies which reported the long-term survival of patients receiving immunotherapy were included. Compared to control group, the 12-month survival (OR = 1.67, 95% CI: 1.31 to 2.12, P < 0.0001) and 18-month survival (OR = 1.98, 95% CI: 1.39 to 2.81, P = 0.0001) were significantly longer in immunotherapy group. The 3-month survival rate (OR = 1.05, 95% CI: 0.36 to 3.06, P = 0.92) and 18-month survival rate (OR = 1.44, 95% CI: 0.98 to 2.12, P = 0.07) were not significantly different between immunotherapy group and control group. The ORR were not significantly different between immunotherapy group and control group (OR = 1.54, 95% CI: 0.65 to 3.66, P = 0.01). Meta-analysis pointed out that in the PD-L1 CPS ≥10 sub group population, the immunotherapy could obviously benefit the patients in tumor response rates (OR = 3.80, 95% CI: 1.89 to 7.61, P = 0.0002). Conclusion: For the treatment of advanced gastric esophageal cancer, the therapeutic efficacy of anti-PD-1/PD-L1 immunotherapy was superior to that of chemotherapy or palliative care.

Abstract   During esophagectomy for cancer, there is no consensus if prophylactic thoracic duct ligation (TDL), with or without thoracic duct resection (TDR), could influence the perioperative outcomes and long-term survival. This systematic review and meta-analysis compared patients who went through esophagectomy associated or not to ligation or resection of the thoracic duct. Methods A systematic review was conducted in PubMed, Embase, Cochrane Library Central and Lilacs (BVS). The inclusion criteria were: (1) studies that compare thoracic duct ligation, with or without resection, and non-thoracic duct ligation; (2) involve adult patients with esophageal cancer; (3) articles that analyses the outcomes—perioperative complications, perioperative mortality, chylothorax development and overall survival; (4) only clinical trials and cohort were accepted. A 95% confidence interval (CI) was used, and random-effects model was performed. Results Fifteen articles were selected, comprising 6,249 patients. TDL did not reduce the risk for chylothorax (Risk difference [RD]: -0.01; 95%CI: −0.02, 0.00). Also, TDL did not influence the risk for complications (RD: -0.02; 95%CI: −0.11, 0.07); mortality (RD: 0.00; 95%CI: −0.00, 0.00); and reoperation rate (RD: -0.01; 95%CI: −0.02, 0.00). TDR was associated with higher risk for postoperative complications (RD: 0.1; 95%CI 0.00, 0.19); chylothorax (RD: 0.02; 95%CI 0.00, 0.03). Both TDL and TDR did not influence the overall survival rate (TDL: HR: 1.17; 95%CI: 0.86, 1.48; and TDR: HR: 1.16; 95%CI: 0.8, 1.51). Conclusion Thoracic duct obliteration with or without its resection during esophagectomy does not change long term survival. Nonetheless, TDR increased the risk for postoperative complications and chylothorax.

DESIGN To perform a meta-analysis of all randomized trials that compared chemotherapy (CT) alone versus combined modality treatment (CT + radiotherapy [RT]) for which individual patient data could be made available. PATIENTS AND METHODS Data on 1,740 patients treated on 14 different trials that included 16 relevant comparisons have been analysed. Eight comparisons were designed to evaluate the benefit of additional RT after the same CT (CT1 v CT1 + RT; additional RT design). Eight comparisons were designed to evaluate whether RT in a combined modality setting can be substituted by CT using either more cycles of the same CT or regimens that contain additional drugs (CT1 + CT2 v CT1 + RT or CT1 v CT2 + RT; parallel RT/CT design). RESULTS Additional RT showed an 11% overall improvement in tumor control rate after 10 years (P = .0001; 95% confidence interval [CI], 4% to 18%). No difference could be detected with respect to overall survival (P = .57; 95% CI, -10% to 4%). In contrast, when combined modality treatment was compared with CT alone in the parallel-design trials, no difference could be detected in tumor control rates (P = .43; 95% CI, -6% to 9%), but overall survival was significantly better after 10 years in the group that did not receive RT (P = .045; 8% difference; 95% CI, 1% to 15%). There were significantly fewer fatal events among patients in continuous complete remission (relative risk [RR], 1.73; 95% CI, 1.17 to 2.53; P = .005) if no RT was given. CONCLUSION Combined modality treatment in patients with advanced-stage Hodgkin's disease overall has a significantly inferior long-term survival outcome than CT alone if CT is given over an appropriate number of cycles. The role of RT in this setting is limited to specific indications.

Aim: The long-term efficacy of cytokine-induced killer cellular therapy for hepatocellular carcinoma patients after curative treatments remains controversial. Methods: A meta-analysis was conducted, and the outcomes were the recurrence rate and overall survival. Results: Eight randomized clinical trials with 1038 participants were included. Compared with the control group, cytokine-induced killer cellular therapy group could reduce 1-year, 3-year recurrence rates, as well as improve 1–5 years overall survival for hepatocellular carcinoma patients (p < 0.05). However, it failed to affect the 5-year recurrence rate and 6-year overall survival (p > 0.05). Conclusion: Cytokine-induced killer cellular adjuvant therapy exerted a favorable role in improving early and long-term efficacy for hepatocellular carcinoma patients.

Abstract Introduction It remains unclear whether minimally invasive pancreaticoduodenectomy (MIPD) and open pancreaticoduodenectomy (OPD) influences long-term survival in periampullary cancers. This review aims evaluate long-term survival between MIPD and OPD for periampullary cancers. Methods A systematic review was performed to identify studies comparing long-term survival after MIPD and OPD. The I2 test was used to test for statistical heterogeneity and publication bias using Egger test. Random-effects meta-analysis was performed for all-cause 5-year (main outcome) and 3-year survival, and disease-specific 5-year and 3-year survival. Meta-regression was performed for the 5- year and 3-year survival outcomes with adjustment for study (region, design, case matching), hospital (centre volume), patient (ASA grade, gender, age), and tumor (stage, neoadjuvant therapy, subtype (i.e. ampullary, distal bile duct, duodenal, pancreatic)). Sensitivity analyses performed on studies including pancreatic ductal adenocarcinoma (PDAC) only. Results The review identified 31 relevant studies. Among all 58,622 patients, 8716 (14.9%) underwent MIPD and 49,875 (85.1%) underwent OPD. Pooled analysis revealed similar 5-year overall survival after MIPD compared with OPD (HR: 0.78, 95% CI 0.50–1.22, p = 0.2). Meta-regression indicated case matching, and ASA Grade II and III as confounding covariates. The statistical heterogeneity was limited (I2 = 12, c2 = 0.26) and the funnel plot was symmetrical both according to visual and statistical testing (Egger test = 0.32). Sensitivity subset analyses for PDAC demonstrated similar 5-year overall survival after MIPD compared with OPD (HR 0.69, 95% CI: 0.32–1.50, p = 0.3). Conclusion Long-term survival after MIPD is similar to OPD. Thus, MIPD can be recommended as a standard surgical approach for periampullary cancers.

This meta-analysis aims to evaluate long-term survival and prognostic factors in patients with metastatic small intestine neuroendocrine tumors (siNETs). Patients with siNETs usually present with advanced disease, limiting curative treatment options. Overall survival seems favorable compared to other cancers but differences in terminology, lack of consistent coding, conflicting results from smaller cohorts, and recent developments of new treatment options make (reliable) survival data difficult to achieve. Nevertheless, accurate survival data are essential for many facets of health care. A systematic literature search was performed, using MEDLINE® (PubMed), EMBASE®, Web of Science, and Cochrane Library up to June 30th, 2021. Studies were included if overall survival data in patients with metastatic siNETs were reported. The results were pooled in a random-effects meta-analysis and are reported as hazard ratios and 95% confidence intervals (CIs). Subgroup analyses and meta-regression were performed to assess the observed heterogeneity and the impact of important prognostic factors. After screening 9,065 abstracts there were 23 studies, published between 1995 and 2021, that met the inclusion criteria, with a total of 8,636 patients. The weighted five- and ten-year overall survival was 67% and 37% respectively. Meta-regression identified younger age and primary tumor resection to be associated with better prognosis. Subgroup analyses showed similar results. This study confirms that in an advanced, metastatic setting, the weighted five-year and 10-year overall survival reveal a favorable prognosis, improving over the last few decades. Meta-regression showed that age at diagnosis is an important prognostic factor.

Abstract Background: Due to better functional outcomes, pylorus-preserving gastrectomy (PPG) has been widely applied for early gastric cancer (EGC) patients as an alternative to distal gastrectomy (DG). However, controversies still persist regarding the surgical efficacy and oncological safety of PPG.Methods: Original studies compared PPG and DG for EGC were searched in PubMed, Embase and the Cochrane Register of Controlled Trials up to December 2019. The weight mean difference, standardized mean difference or odds risk were used to calculate the short-term and long-term outcomes between the two groups.Results: Twenty-one non-randomized controlled studies comprising 4871 patients (1955 in the PPG group and 2916 in the DG group) were enrolled in this systematic review and meta-analysis. PPG showed longer hospital day, decreased harvested lymph nodes and more delayed gastric emptying. However, PPG had the benefits of lower incidence of anastomosis leakage, early dumping syndrome, gastritis and bile reflux and better recovery of total protein, albumin. hemoglobin and weight. No difference was found in operative time, blood loss and overall complications. Moreover, the long-term survival and recurrence rate were similar in two groups.Conclusion: Owing to the non-inferiority of surgery and oncology outcomes and the superiority of function outcomes in PPG, we revealed that PPG can be clinically applicable instead of DG in EGC. However, more high-quality comparative studies and randomized clinical trials (RCTs) would be required for further confirmation.

Background/Aim: We investigated the oncologic outcomes in elderly patients who underwent endoscopic submucosal dissection (ESD) for early gastric cancer (EGC) by focusing on the impact of comorbidities, sarcopenia, and nutritional status. Methods: Between 2005 and 2016, 280 patients aged ≥ 80 years with 289 EGCs underwent ESD at a tertiary care center. The short- and long-term survival outcomes were assessed. Cox regression analysis was used to identify factors associated with survival, including clinicopathologic factors and abdominal muscle area measured by computed tomography. Results: The rates of en bloc, R0, and, curative resection were 99.3%, 90.0%, and 69.2%, respectively. The rates of post-ESD bleeding and perforation rates were 2.1% and 3.1%, respectively, and no cases showed significant life-threatening adverse events. Over a median follow-up period of 70.5 months, the 3- and 5-year overall survival (OS) rates were 89.5% and 77.1%, respectively; of the114 patients who died, only four (3.5%) were due to gastric cancer. A total of 173 (61.8%) had sarcopenia, and they had lower rates of 3-year (88.4% vs. 91.4%) and 5-year (73.1% vs. 84.0%; p = 0.046) OS than did those without sarcopenia. In multivariable analyses, prognostic nutritional index (hazard ratio [HR], 0.93; 95% confidence interval [CI]: 0.90–0.98; p = 0.002) and Charlson comorbidity index (HR 1.19; 95% CI: 1.03–1.37; p = 0.018) were significant factors associated with overall survival. Conclusions: ESD was a feasible and safe therapeutic method to use in elderly patients, whose long-term survival was significantly associated with nutritional status and comorbidities. These results suggest the need for a possible extension of the curative criteria for ESD in elderly patients with EGC.
