Objectives: To evaluate the survival outcome, patterns of failure, and complications in patients treated with postoperative chemoradiation therapy in stages II-III of distal gastric cancer. Materials & methods: Prospective study on 58 patients with stages II-III gastric adenocarcinoma, underwent distal gastrectomy and D1 or D2 dissection, completed post operative chemoradiation therapy with capecitabine and 4-6 cycles with EOX regimen at Oncology center of Hue central hospital from 01/2013 to 12/2015. Results: Mean age was 55.16 ± 9.1, male/female ratio: 3/1, recurrence was common in the first year after treatment (62.5%), the average time of recurrence and metastasis were 13.50 ± 7.29 months and 18.75 ± 8.97 months, respectively. The mean overall survival was 41.21 ± 21.06 months. The mean disease free survival was 36.22 ± 22.64 months. The mean overall survival: stage II was 41.88 ± 20.78 months; stage III was 39.59 ± 22.27. The mean overall survival for extention of primary tumors: T3 was 40.79 ± 19.61 months; T4 was 41.33 ± 24.80 months. The mean overall survival for extensive of lymph nodes: N (-) was 41.16 ± 20.51 months, N (+) was 41.26 ± 22.06 months. Toxicity levels recorded as follow: leukopenia was mainly on grade 1 and 2 (33.6%), neutropenia was mostly on grade 1 and 2 (26.8%), as well as thrombocytopenia (8.6%); hemoglobin decrease was on grade 1 and 2 in most cases (41.4%); toxicity symptoms on digestive system like nausea-vomitting, diarrhea was mainly on grade 1 and 2. Conclusion: Postoperative chemoradiation therapy helps to improve local and regional recurrence in locally advanced gastric cancer with acceptable toxicities.

The Impact

Background and Objectives: The prognosis of metastatic or unresectable gastric cancer is dismal, and the benefits of the palliative resection of primary tumors with noncurative intent remain controversial. This study aimed to evaluate the impact of palliative gastrectomy (PG) on overall survival in gastric cancer patients. Materials and Methods: One hundred forty-eight gastric cancer patients who underwent PG or a nonresection (NR) procedure between January 2011 and 2017 were retrospectively reviewed to select and analyze clinicopathological factors that affected prognosis. Results: Fifty-five patients underwent primary tumor resection with palliative intent, and 93 underwent NR procedures owing to the presence of metastatic or unresectable disease. The PG group was younger and more female dominant. In the PG group, R1 and R2 resection were performed in two patients (3.6%) and 53 patients (96.4%), respectively. The PG group had a significantly longer median overall survival than the NR group (28.4 vs. 7.7 months, p < 0.001). Multivariate analyses revealed that the overall survival was significantly better after palliative resection (hazard ratio (HR), 0.169; 95% confidence interval (CI), 0.088–0.324; p < 0.001) in patients with American Society of Anesthesiologists Physical Status (ASA) scores ≤1 (HR, 0.506; 95% CI, 0.291–0.878; p = 0.015) and those who received postoperative chemotherapy (HR, 0.487; 95% CI, 0.296–0.799; p = 0.004). Among the patients undergoing palliative resection, the presence of <15 positive lymph nodes was the only significant predictor of better overall survival (HR, 0.329; 95% CI, 0.121–0.895; p = 0.030). Conclusions: PG might lead to the prolonged survival of certain patients with incurable gastric cancer, particularly those with less-extensive lymph-node metastasis.

Gastric cancer is the third most common cause of cancer deaths worldwide. Despite evidence-based recommendation for treatment, the current treatment patterns for all stages of gastric cancer remain largely unexplored. This study investigates trends in the treatments and survival of gastric cancer. The National Cancer Database was used to identify gastric adenocarcinoma patients from 2004–2016. Chi-square tests were used to examine subgroup differences between disease stages: Stage I, II/III and IV. Multivariate analyses identified factors associated with the receipt of guideline concordant care. The Kaplan–Meier method was used to assess three-year overall survival. The final cohort included 108,150 patients: 23,584 Stage I, 40,216 Stage II/III, and 44,350 Stage IV. Stage specific guideline concordant care was received in only 73% of patients with Stage I disease and 51% of patients with Stage II/III disease. Patients who received guideline consistent care had significantly improved survival compared to those who did not. Overall, we found only moderate improvement in guideline adherence and three-year overall survival during the 13-year study time period. This study showed underutilization of stage specific guideline concordant care for stage I and II/III disease.

Abstract Background This study compared the long-term efficacy of different durations of adjuvant chemotherapy for patients with gastric cancer after radical gastrectomy with D2 lymphadenectomy. Methods We retrospectively identified 428 patients with stage II–III gastric cancer who underwent D2 gastrectomy between 2009 and 2016. Patients were divided into four groups according to the duration of adjuvant chemotherapy, including 0 week (no adjuvant, group A), 20 to 24 weeks (completed 7–8 cycles every 3 weeks or 10–12 cycles every 2 weeks, group B), and 12 to18 weeks (completed 4–6 cycles every 3 weeks or 6–9 cycles every 2 weeks, group C), and less than 12 weeks (received up to 3 cycles every 3 weeks or 5 cycles every 2 weeks, group D). The chemotherapy regimens included XELOX, SOX, and FOLFOX. 5-year overall survival (OS) and disease-free survival (DFS) were analyzed. Results The 5-year OS rates for groups A, B, C, and D were 52.3, 73.7, 72.0, and 53.3%, respectively, and the 5-year DFS rates were 50.0, 68.0, 65.4, and 50.0%, respectively. OS and DFS were higher in group B than in groups A and D. Similarly, patients in group C were more likely to have higher OS and DFS than those in groups A and D. Meanwhile, there were no significant differences in OS and DFS between groups B and C. The multivariate analysis confirmed with high statistical significance the efficacy of complete courses of adjuvant chemotherapy, and, among them, the similar impact of 4–6/6–9 and 7–8/10–12 cycles, resulting in similar HRs vs Group A (0.52 and 0.42, respectively). Conclusions To reduce toxicity and maintain efficacy, XELOX or SOX chemotherapy regimens administered for 4–6 cycles every 3 weeks or FOLFOX regimen for 6–9 cycles every 2 weeks might be a favorable option for patients with stage II–III gastric cancer after D2 gastrectomy. Prospective multicenter clinical trials with adequate sample sizes are necessary to verify these findings.

5593 Background: Although well established in cervical cancer, it is unclear whether time from initiation to completion of radiation therapy for vulvar cancer affects survival outcomes. We seek to assess if completion of radiation, either alone (RT) or as concurrent chemoradiation (CRT), within a planned timeframe in locally advanced squamous cell vulvar cancer impacts overall survival (OS). Methods: Women 18 years or older with FIGO stage II to IVA vulvar cancer who received external beam RT or CRT as part of their initial treatment course were identified from the National Cancer Database from 2004-2017. Patients with non-squamous cell carcinoma histology or who received systemic cytotoxic therapies as primary treatment were excluded. Patients who received less than 20 fractions of radiation were also excluded. Time to radiation completion was the number of days from the initiation to completion of radiation. The delay of radiation completion was calculated as the difference between the actual time to radiation completion and predicted duration of radiation. Types of treatment (RT and CRT) were both stratified into groups based on the delay of radiation completion, less than 7 days or greater than 7 days. Chi-square, Fisher Exact ANOVA and Kruskal-Wallis tests were used for analysis. Kaplan-Meier curves with log-rank tests were fit for univariate time-to-event analysis. Multivariable Cox proportional hazard models were fit to assess effects after controlling for confounding. Results: There were 2378 patients identified for analysis (n = 856 RT and n = 1522 CRT). Median age was 67 (IQR 56-78) and the CRT group was younger (p < 0.0001) than the RT group. The majority were white (88.35%) with advanced FIGO stage III or IVA (72.29 %) disease. Median dose of total radiation was 5720 cGy (IQR 5040-6300) with higher doses observed in the greater than 7 days delay group versus less than 7 days, (p < 0.0001). Median follow up was 27.2 (IQR 11.8-57.9) months. For both cohorts, completion of treatment with delay less than 7 days resulted in significant improvement in median survival when compared to treatment completion delay of more than 7 days: RT (Median OS 34.9 versus 21.6 months, p < 0.01) and CRT (58 versus 41.3 months, p < 0.01). On multivariate subset analysis, both completion of CRT and RT were associated with improved OS when treatment was completed with less than 7 days delay vs greater than 7 days delay, CRT (HR 0.869 [95%CI 0.758-0.997]), RT (HR 0.820 [95%CI 0.698-0.964]). Advanced FIGO stage IVA was associated with the greatest increase in hazard of death, (HR 1.758 [95%CI 1.516-2.039]), compared to FIGO stage II. Conclusions: Completion of radiation with less than 7 days delay is associated with improved overall survival, which is independent of concurrent chemotherapy. These findings suggest that strategies to minimize delays in radiation treatment are crucial in treating locally advanced vulvar cancer.

Gastric adenocarcinoma studies show improved survival for Asians but have not reported stage-specific overall survival (OS) or disease-specific survival (DSS) by race. The Surveillance, Epidemiology and End Results database was queried for cases of gastric adenocarcinoma between 1998 and 2008. We evaluated OS and DSS by race and stage. Number of assessed lymph nodes was compared among surgical patients. Of 49,058 patients with complete staging data, 35,300 were white, 7709 were Asian, and 6049 were black. Asians had significantly better OS for all stages ( P < 0.001) and significantly better DSS for Stages I ( P < 0.0001) and II ( P = 0.0006). As compared with blacks, whites had significantly better DSS for Stages I ( P < 0.0001), II ( P = 0.0055), III ( P = 0.0165), and IV ( P < 0.0001). Among the 28,133 (57%) surgical patients, average number of evaluated lymph nodes was highest for Asians ( P < 0.0001). Among surgical patients with 15 or more nodes evaluated, DSS was worse in blacks with Stage I disease ( P < 0.05). Blacks with gastric adenocarcinoma have a worse DSS, which disappears when surgical treatment includes adequate lymphadenectomy. Race-associated survival differences for gastric adenocarcinoma might simply reflect variations in surgical staging techniques and socioeconomic factors.

Phase Iii Trials

Patients with locally advanced or metastatic gastric adenocarcinoma received an i.v. bolus of 4′-epi-doxorubicin, 75/mg/m2/cycle, every 21 days. Partial responses were observed in 5 of 23 evaluable patients (21.7%). Treatment was generally well tolerated and toxicity was mild. The response rate to epirubicin appears to be very similar to that reported for doxorubicin. Larger doses of epirubicin could be safely used in future studies, and further evaluation of epirubicin in phase III trials is indicated.

4540 Background: Up to now the value of 2nd-line therapy for metastatic gastric cancer is unclear. So far there are no randomized phase III data comparing 2nd-line chemotherapy to BSC. Irinotecan has proven activity in 1st-line therapy. In this randomized phase III study we compared irinotecan to BSC to evaluate the value of 2nd- line chemotherapy for gastric cancer. Methods: Prospective multicenter randomized phase III study, open label. Eligibility: Metastatic or locally advanced gastro-esophageal junction or gastric adenocarcinoma. Objective tumor progession (PD) within 6 months after 1st- line chemotherapy. ECOG PS 0–2. Statistics: Primary endpoint: Overall survival (OS). Hypothesis: H1: OS(Irinotecan)>OS(BSC). Calculated number of pts needed (power 80%, alpha error 5%): 60 pts per arm. Stratification for a) PD less versus (vs) more than 3 months after 1st line chemotherapy, b) ECOG PS 0/1 vs 2. Treatment: Arm A: Irinotecan 250mg/m2 q3w (1st cycle) to be increased to 350 mg/m2, depending on toxicity. Arm B: BSC Results: Between Oct 2002 and Dec 2006 40 pts were randomized. The study was closed prematurely due to poor accrual. Arm A:21 pts, arm B 19 pts. Median age A: 58 yrs (43–73), B: 55 yrs (35–72); PD less vs more than 3 months after 1st-line chemotherapy: A: 18 / 3, B: 17 / 2pts. ECOG PS 0/1 vs 2: A: 17/ 4, B: 14/ 5pts. Pre-treatment with cisplatin: A: 21, B:19 pts. Arm A: 68 cycles administered in 21 pts. Toxicity: (main CTC grade 3/ 4): Nausea 1 pt, vomiting 1 pt, diarrhoea: 5 pts, neutropenic fever: 2 pts, data incomplete 6 pts. In 37% of 19 evaluable pts irinotecan dose was escalated to 350mg/m2. Response (19 pts evaluable): No objective responses, SD 58%, PD 42%. Improvement of tumor related symptoms: 44% of pts in arm A, 5% in arm B. Survival: (evaluable pts arm A 21, arm B 18): median survival arm A: 123 days (95%CI 95–216), arm B 72.5 days (95%CI 41–106); OS: HR=2.85 (95%CI 1.41–5.79), Logrank test (two-sided): p=0.0027. Conclusions: To our knowledge this is the first randomized phase III study investigating 2nd- line chemotherapy in gastric cancer. Irinotecan as 2nd-line chemotherapy significantly prolongs overall survival compared to BSC. 2nd-line chemotherapy can now be considered as a proven option in gastric cancer. [Table: see text]
