Purpose: Perioperative chemotherapy improves survival outcomes in locally advanced (LA) gastric cancer. Materials and Methods: We retrospectively analyzed patients with LA gastric cancer who were offered perioperative chemotherapy consisting of epirubicin, oxaliplatin, and capecitabine (EOX) from May 2013 to December 2015 at Tata Memorial Hospital in Mumbai. Results: Among the 268 consecutive patients in our study, 260 patients (97.0%) completed neoadjuvant chemotherapy, 200 patients (74.6%) underwent D2 lymphadenectomy, and 178 patients (66.4%) completed adjuvant chemotherapy. The median follow-up period was 17 months. For the entire cohort, the median overall survival (OS), 3-year OS rate, median progression-free survival (PFS), and 3-year PFS rate were 37 months, 64.4%, 31 months, and 40%, respectively. PFS and OS were significantly inferior in patients who presented with features of obstruction than in those who did not (P=0.0001). There was no difference in survival with respect to tumor histology (well to moderately differentiated vs. poorly differentiated, signet ring vs. non-signet ring histology) or location (proximal vs. distal). Survival was prolonged in patients with an early pathological T stage and a pathological node-negative status. In a multivariate analysis, postoperative pathological nodal status and gastric outlet obstruction on presentation significantly correlated with survival. Conclusions: EOX chemotherapy with curative resection and D2 lymphadenectomy is a suggested alternative to the existing perioperative regimens. The acceptable postoperative complication rate and relatively high resections, chemotherapy completion, and survival rates obtained in this study require further evaluation and validation in a clinical trial.

Purpose: Despite an increased acceptance of laparoscopic gastrectomy (LG) in early gastric cancer (EGC), there is insufficient evidence for its oncological safety in advanced gastric cancer (AGC). This is a prospective phase II clinical trial to evaluate the feasibility of LG with D2 lymph node dissection (LND) in AGC. Materials and Methods: The primary endpoint was set as 3-year disease-free survival (DFS). The eligibility criteria were as follows: 20-80 years of age, cT2N0-cT4aN3, American Society of Anesthesiologists score of 3 or less, and no other malignancy. Patients were enrolled in this single-arm study between November 2008 and May 2012. Exclusion criteria included cT4b or M1, or having final pathologic results as EGC. All patients underwent D2 lymphadenectomy. Three-year DFS rates were estimated by the Kaplan-Meier method. Results: A total of 157 patients were enrolled. The overall local complication rate was 10.2%. Conversion to open surgery occurred in 11 patients (7.0%). The mean follow-up period was $55.0{\pm}20.4months$ (1-81 months). The cumulative 3-year DFS rates were 76.3% for all stages, and 100%, 89.3%, 100%, 88.0%, 71.4%, and 35.3% for stage IB, IIA, IIB, IIIA, IIIB, and IIIC, respectively. Recurrence was observed in 37 patients (23.6%), including hematogenous (n=6), peritoneal (n=13), locoregional (n=1), distant node (n=8), and mixed recurrence (n=9). Conclusions: In addition to being technically feasible for treatment of AGC in terms of morbidity, LG with D2 LND for locally advanced gastric cancer showed acceptable 3-year DFS outcomes.

영남대학병원에서는 1988년 6월 15일부터 1990년 9월 15일까지 절제가능한 국소 진행된 위암 환자중 원격 전이를 추인할 수 없었던 환자 총 28명을 prospective randomized protocol에 의한 치료를 계획하였다. 28명중, 개복후 절제가 불가능했던 환자 3명과 stage la로 판명된 환자 1명을 제외 한 24명에서 외과적 근치절제수술후 1500cGy를 giuev의 전자선을 이용하여 1회에 조사하였다. 외부 방사선 치료는 수술후 4주 이내에 시작하여 하루 180 cGy 주 5회 치료법으로 $4300\sim4500$ cGy를 조사하였다. 항암요법은 protoco떼 의하여 5-FU, Mitomycin-C, Adriamycin, Uraful을 여러 가지 조합으로 투여하였다. 3개월에서 31개월 간의 추적기간 중에 방사선 조사와 관계되는 심한 부작용은 보고되지 않았다. 짧은 추적 기간이므로 생존율을 산출할 수 없겠으나 수술중 방사선치료, 외부방사선 치료와 여러가지 항암제를 병합 투여하였음에도 불구하고 심한 부작용이 발견되지 않았을 뿐 아니라 현재까지 국소재발이 한 예에서도 발견되지 않았음으로 수술중 방사선 치료의 국소 재발의 억제 및 방지의 효과가 확실시되며 계속되는 추적 검사에서도 좋은 생존율이 기대된다.
