Abstract
BACKGROUND Advances in perioperative chemotherapy have improved outcomes in patients with gastric cancers (GC). This strategy leads to tumour downstaging and may result in a pathologic complete response (pCR). The study aimed to evaluate the predictors of pCR and determine the impact of pCR on long-term survival. METHODS At the Department of Gastrointestinal and HPB Oncology at the Tata Memorial Centre, Mumbai, 1001 consecutive patients with locally advanced GCs undergoing radical resection following neoadjuvant chemotherapy from January 2005 to June 2022 were included. RESULTS At a median follow-up of 61 months, the median OS was 53 months with a 5-year OS of 46.8 %. Ninety-five patients (9.49 %) realized pCR. Non-signet and well-differentiated histology were associated with pCR. pCR was significantly associated with improved OS, 5-year OS 79.2 % vs 43.2 % (HR 0.30, p < 0.001). On multivariable analysis, the realization of pCR and completion of adjuvant chemotherapy had superior OS. Whereas, signet-ring histology, linitis-like tumours, and high lymph node ratio had adverse outcomes. CONCLUSION Tumour grade and signet-ring histology predict achievement of pCR in locally advanced GCs after neoadjuvant chemotherapy. Patients with pCR have significantly improved survival. Future neoadjuvant strategies should focus on enhancing pCR rates to improve overall outcomes.

Abstract
BACKGROUND AND OBJECTIVES There is limited real-world data on the efficacy of 2-weekly cycles of docetaxel, oxaliplatin, leucovorin, and fluorouracil (FLOT) compared to epirubicin, oxaliplatin, and capecitabine (EOX) as perioperative therapy in esophagogastric adenocarcinomas (EGAC). METHODS The data of 611 patients with EGAC treated with perioperative chemotherapy and planned for curative resection between January 2013 and December 2019 were retrieved. Patients receiving EOX and a dose-modified version of FLOT (mFLOT) were evaluated. A 1:1 matching, using age, tumour location, signet ring histology, and Eastern Cooperative Oncology Group performance status, without replacement was performed by using nearest neighbour matching method. The primary endpoint of the study was 3-year event-free survival (EFS). RESULTS A total of 593 patients (261 with EOX and 332 with mFLOT) were matched. One hundred and nighty-eight patients (76%) and 285 patients (86%) in the EOX and mFLOT cohorts underwent curative resection, respectively (p = 0.002). With a median follow-up of 35 and 53 months, respectively, the primary outcome of 3-year EFS was statistically superior in patients receiving mFLOT as compared to the EOX regimen (60% vs. 39%; p < 0.001). There was a greater incidence of grade 3 and grade 4 neutropenia (neoadjuvant: 18% vs. 2%; p < 0.001, adjuvant: 18% vs. 1%; p = 0.001) and febrile neutropenia (neoadjuvant: 8% vs. 1.1%; p < 0.001, adjuvant: 6% vs. 0; p = 0.001) with mFLOT. INTERPRETATION AND CONCLUSION mFLOT is associated with improved resection rates and survival in comparison to EOX as perioperative therapy in gastric adenocarcinomas in this large real-world cohort, with manageable increase in clinically relevant toxicities such as grade 3 and grade 4 febrile neutropenia and neutropenia.

Abstract
PURPOSE The study aimed to investigate the prognosis and safety of perioperative chemotherapy (PC) compared with adjuvant chemotherapy (AC). METHODS We systematically searched and assessed studies in PubMed, Embase, and the Cochrane Library from inception to 1st September 2022. RESULTS Eighteen studies were eligible for the analysis, including 4686 patients in total. Our study found that patients with resectable gastric cancer undergoing PC had favorable prognosis on OS (HR 0.77; 95% CI 0.69-0.87) and DFS (HR 0.76; 95% CI 0.69-0.84) than those who undergoing AC. Addition of neoadjuvant chemotherapy (NAC) to AC provided higher R0 resection rate but did not increase the risk of postoperative complication rate and most of the adverse event rates. CONCLUSION Our study demonstrated that PC shows better OS and DFS in Asians with resectable gastric cancer compared with AC. PC should be preferred because of its favorable prognosis and similar safety.

Abstract
BACKGROUND Access to care and barriers to achieving health equity remain persistent and prevailing issues in the USA, particularly for low socioeconomic (L-SES) populations. Previous studies have shown that public insurance (a surrogate marker for L-SES) is an independent predictor of emergent hernia repair. However, the impact of insurance type on postoperative healthcare utilization, including emergency department (ED) care, following ventral hernia repair (VHR) remains unknown. METHODS The 2013-2020 Abdominal Core Health Quality Collaborative (ACHQC) database was used to identify patients aged 18-64 undergoing ventral hernia repair (VHR) who had private or Medicaid insurance. Patients with no health insurance were also included. Using insurance type, the cohort was divided into three groups: private, public (Medicaid), and uninsured (self-pay). Multivariate logistic regression analyses were used to assess the impact of insurance type on emergency department (ED) utilization, postoperative complications, and readmission. RESULTS A total of 17,036 patients undergoing VHR were included in the study, out of which 13,980 (85.8%) had private insurance, 2,451 (8.4%) had public, and 605 (5.8%) were uninsured. Following adjustment for demographics (age, gender, race), comorbidities (hypertension, diabetes, smoking), and clinical characteristics (emergent procedure, ASA class, surgical approach), public insurance was associated with 1.7 times greater odds of returning to the emergency department (ED) within 30 days of surgery compared to private insurance (95% CI 1.4, 2.0; p = 0.01). Public insurance or being uninsured was also associated with increased odds of experiencing any postoperative complications compared to those who were privately insured (public: OR 1.3, p < 0.01; self-pay: OR 1.67, p < 0.01). CONCLUSION Our study demonstrates that public and self-pay insurance are associated with increased emergency department (ED) utilization and worse postoperative outcomes compared to those with private insurance. In an effort to promote health equity, healthcare providers need to assess how parameters beyond physical presentation may impact a patient's health.

Abstract
Randomized control trials have established systemic therapy as an integral part of treatment for gastric cancer, but the ideal sequence of surgery and chemotherapy is not known. In the West, peri-operative chemotherapy (based on MAGIC and FLOT4 trials) is the standard of care vs. in the East, D2 gastrectomy followed by adjuvant chemoradiation (based on ARTIST trial) or adjuvant chemotherapy (based on S-1 and CLASSIC trials) is more common. In this issue, Singh et al. ask if perioperative chemotherapy or adjuvant chemotherapy portends a survival advantage specifically for patients with resectable distal gastric cancer who underwent D2 lymphadenectomy.1.
