Abstract
BACKGROUND Outside of clinical trials, real-world data of advanced gastric cancers (AGCs) managed with perioperative or adjuvant chemotherapy with a backbone of D2 lymphadenectomy is limited. PATIENTS AND METHODS Curative resections for gastric adenocarcinoma between January 2003 and January 2020 at the Tata Memorial Centre were analyzed, comparing three time periods marking major increments in annual gastric resections (GRs). RESULTS 1657 radical gastric resections were performed with a morbidity and mortality rate of 34.9% and 1.4%, respectively. Over three consecutive periods, the number of annual GRs increased from 56/year to 97/year to 156/year (P < 0.001) with a significant escalation in surgical magnitude and complexity. Improvement in surgical quality indicators (median lymph node yield from 15 to 25, P < 0.001 and margin negativity from 8.2 to 5.5%, P = 0.002) was observed with no corresponding increase in severe complications (6.9%) or mortality (1.4%). The proportion of distal and signet ring cancers was found to decrease over time, with an increase in proximal cancers and younger age at presentation. Overall, 90% of GRs were for AGCs with a median overall survival (OS) of 4.4 years (± 6 months), and 5-year OS rate of 47.6% (± 1.9%). CONCLUSIONS Change in pattern of tumor characteristics was observed. Aggressive treatment options for AGC were employed progressively with excellent survival. With increase in volumes, improvements in surgical quality indicators, and a relative improvement in postoperative mortality was observed. These results provide a roadmap for developing dedicated gastric cancer centers.

Association between hospital surgical case volume and postoperative mortality in patients undergoing gastrectomy for gastric cancer: a systematic review and meta-analysis. Int J Surg 2023; 109:936-945. [PMID: 36917144 PMCID: PMC10389614 DOI: 10.1097/js9.0000000000000269] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/25/2022] [Accepted: 02/06/2023] [Indexed: 03/15/2023]
Abstract
BACKGROUND Postoperative mortality is an important indicator for evaluating surgical safety. Postoperative mortality is influenced by hospital volume; however, this association is not fully understood. This study aimed to investigate the volume-outcome association between the hospital surgical case volume for gastrectomies per year (hospital volume) and the risk of postoperative mortality in patients undergoing a gastrectomy for gastric cancer. METHODS Studies assessing the association between hospital volume and the postoperative mortality in patients who underwent gastrectomy for gastric cancer were searched for eligibility. Odds ratios were pooled for the highest versus lowest categories of hospital volume using a random-effects model. The volume-outcome association between hospital volume and the risk of postoperative mortality was analyzed. The study protocol was registered with Prospective Register of Systematic Reviews (PROSPERO). RESULTS Thirty studies including 586 993 participants were included. The risk of postgastrectomy mortality in patients with gastric cancer was 35% lower in hospitals with higher surgical case volumes than in their lower-volume counterparts (odds ratio: 0.65; 95% CI: 0.56-0.76; P <0.001). This relationship was consistent and robust in most subgroup analyses. Volume-outcome analysis found that the postgastrectomy mortality rate remained stable or was reduced after the hospital volume reached a plateau of 100 gastrectomy cases per year. CONCLUSIONS The current findings suggest that a higher-volume hospital can reduce the risk of postgastrectomy mortality in patients with gastric cancer, and that greater than or equal to 100 gastrectomies for gastric cancer per year may be defined as a high hospital surgical case volume.

Abstract
AIM: To evaluate whether lymph node pick up by separate stations could be an indicator of patients submitted to appropriate surgical treatment.
METHODS: One thousand two hundred and three consecutive gastric cancer patients submitted to radical resection in 7 general hospitals and for whom no information was available on the extension of lymphatic dissection were included in this retrospective study.
RESULTS: Patients were divided into 2 groups: group A, where the stomach specimen was directly formalin-fixed and sent to the pathologist, and group B, where lymph nodes were picked up after surgery and fixed for separate stations. Sixty-two point three percent of group A patients showed < 16 retrieved lymph nodes compared to 19.4% of group B (P < 0.0001). Group B (separate stations) patients had significantly higher survival rates than those in group A [46.1 mo (95%CI: 36.5-56.0) vs 27.7 mo (95%CI: 21.3-31.9); P = 0.0001], independently of T or N stage. In multivariate analysis, group A also showed a higher risk of death than group B (HR = 1.24; 95%CI: 1.05-1.46).
CONCLUSION: Separate lymphatic station dissection increases the number of retrieved nodes, leads to better tumor staging, and permits verification of the surgical dissection. The number of dissected stations could potentially be used as an index to evaluate the quality of treatment received.

Abstract
BACKGROUND Advanced gastric cancer in the upper or middle third of the stomach is routinely treated with a total gastrectomy, albeit in some cases with higher morbidity and mortality. The aim of this study was to describe the morbimortality and survival results in total gastrectomy in a single center. METHODS This retrospective study included patients with gastric adenocarcinoma treated with a total gastrectomy at a single Brazilian cancer center between January 1988 and December 2011. Clinical, surgical, and pathology information were analyzed through time, with three 8-year intervals being established. Prognostic factors for survival were evaluated only among the patients treated with curative intent. RESULTS The study comprised 413 individuals. Most were male and their median age was 59 years. The majority of patients had weight loss and were classified as American Society of Anesthesiologists 2. A curative resection was performed in 336 subjects and a palliative resection was performed in 77 subjects. Overall morbidity was 37.3% and 60-day mortality was 6.5%. Temporal analysis identified more advanced tumors in the first 8-year period along with differences in the surgical procedure, with more limited lymph node dissections. In addition, a significant decrease in mortality was observed, from 13 to 4%. With a median follow-up of 74 months among living patients, median survival was 56 months, and 5-year overall survival was 49.2%. Weight loss, lymphadenectomy, tumor size, and T and N stages were prognostic factors in multivariate analysis. CONCLUSIONS Total gastrectomy is a safe and feasible treatment in experienced hands. Advances in surgical technique and perioperative care have improved outcomes through time.
