Resectable Gastric Cancer

TPS4141 Background: Optimal management of patients with resectable gastric cancer remains unknown. Since the INT0116 and MAGIC trials, there are 2 standards of care for adjuvant therapy: postoperative chemoradiotherapy (CRT) and perioperative ECF chemotherapy. The important question arising from these studies is whether CRT is superior to chemotherapy alone as adjuvant therapy. This randomized phase II/III trial will compare CRT to chemotherapy alone in the preoperative setting. Methods: Patients with resectable adenocarcinoma of the stomach or gastroesophageal junction will be randomized to receive either preoperative chemotherapy alone (ECFx3 as per MAGIC regimen) or preoperative CRT (ECFx2 followed by 45Gy of radiation with concurrent 5-FU). Following surgery, both groups will receive 3 further cycles of ECF. The trial is being conducted in two Parts; Part I (phase II component) will recruit 120 patients with the aim of demonstrating sufficient efficacy and safety of preoperative CRT, as well as trial feasibility. Part II (phase III component) will recruit a further 632 patients to provide a total of 752. The primary endpoint for Part I is pathological complete response rate, and for Part 2 it is overall survival. The trial includes formal quality of life and biological sub-studies. In addition, the trial incorporates a rigorous quality assurance program that includes real time central review of radiotherapy plans and central review of surgical technique. Current status: This study is an international, intergroup trial led by the Australasian Gastro-Intestinal Trials Group (AGITG), in collaboration with the Trans-Tasman Radiation Oncology Group (TROG), European Organisation for Research and Treatment of Cancer (EORTC) and the NCIC Clinical Trials Group. To date, 36 patients have been recruited from 20 sites in Australia and New Zealand; European and Canadian sites will commence recruitment in 2012.

Purpose S-1 plus cisplatin is considered highly active in Japanese gastric cancer patients. We conducted a phase II multi-institutional trial, in the West, in patients with untreated advanced gastric or gastroesophageal junction adenocarcinoma to evaluate activity and safety of this combination. Methods Patients received cisplatin intravenously at 75 mg/m2 on day 1 and S-1 orally at 25 mg/m2/dose bid (50 mg/m2/d) on days 1 to 21, repeated every 28 days. Patients with histologic proof of gastric or gastroesophageal junction adenocarcinoma with a Karnofsky performance status (KPS) of ≥ 70% and near-normal organ function were eligible. All patients provided a written informed consent. To observe a 45% confirmed overall response rate (ORR), 41 assessable patients were needed. Results All 47 patients were assessed for safety and survival, and 41 patients were assessed for ORR. The median age was 56 years and median KPS was 80%. The median number of chemotherapy cycles was four. The confirmed ORR was 51% (95% CI, 35% to 67%) and it was 49% by an independent review. At the 6-month interval, 71% of patients were alive, with a median survival time of 10.9 months. Frequent grade 3 or 4 toxicities included fatigue (26%), neutropenia (26%), vomiting (17%), diarrhea (15%), and nausea (15%); however, stomatitis (2%) and febrile neutropenia (2%) were uncommon. There was one (2%) treatment-related death. Conclusion S-1 plus cisplatin is active against gastric cancer and has a favorable toxicity profile. A global phase III study of S-1 plus cisplatin versus fluorouracil plus cisplatin currently is accruing patients.

Background: Although surgical resection is necessary to cure the locally advanced gastric cancer, it is sometimes difficult for extensive nodal metastasis such as para-aortic nodal disease or bulky nodal metastasis around the major gastric branched arteries. We had conducted several Phase II studies and clarified preoperative chemotherapy with doublet regimen followed by surgery markedly improved the survival for this disease. Recently, preoperative chemotherapy with docetaxel, oxaliplatin and S-1 (DOS) showed promising efficacy and acceptable feasibility for resectable advanced gastric cancer. Aim: To describe the design and rationale for the multi-institutional, single-arm, Phase II trial of systemic chemotherapy with DOS followed by surgery in advanced gastric cancer with extensive lymph node metastasis (JCOG1704). If efficacy and safety of DOS can be shown, we will conduct a Phase III trial comparing preoperative DOS and current standard cisplatin and S-1. Trial registration: jRCTs031180028.

PurposePatients with locally advanced gastric cancer benefit from combined pre- and postoperative chemotherapy, although fewer than 50% could receive postoperative chemotherapy. We examined the value of purely preoperative chemotherapy in a phase III trial with strict preoperative staging and surgical resection guidelines.Patients and MethodsPatients with locally advanced adenocarcinoma of the stomach or esophagogastric junction (AEG II and III) were randomly assigned to preoperative chemotherapy followed by surgery or to surgery alone. To detect with 80% power an improvement in median survival from 17 months with surgery alone to 24 months with neoadjuvant, 282 events were required.ResultsThis trial was stopped for poor accrual after 144 patients were randomly assigned (72:72); 52.8% patients had tumors located in the proximal third of the stomach, including AEG type II and III. The International Union Against Cancer R0 resection rate was 81.9% after neoadjuvant chemotherapy as compared with 66.7% with surgery alone (P = .036). The surgery-only group had more lymph node metastases than the neoadjuvant group (76.5% v 61.4%; P = .018). Postoperative complications were more frequent in the neoadjuvant arm (27.1% v 16.2%; P = .09). After a median follow-up of 4.4 years and 67 deaths, a survival benefit could not be shown (hazard ratio, 0.84; 95% CI, 0.52 to 1.35; P = .466).ConclusionThis trial showed a significantly increased R0 resection rate but failed to demonstrate a survival benefit. Possible explanations are low statistical power, a high rate of proximal gastric cancer including AEG and/or a better outcome than expected after radical surgery alone due to the high quality of surgery with resections of regional lymph nodes outside the perigastic area (celiac trunc, hepatic ligament, lymph node at a. lienalis; D2).

Definition Of

Gastric cancer is a leading cause of cancer death worldwide. Systemic treatment comprising chemotherapy and targeted therapy is the standard of care in advanced/metastatic gastric cancer. Comprehensive molecular characterization of gastric adenocarcinomas by the TCGA Consortium and ACRG has resulted in the definition of distinct molecular subtypes. These efforts have in parallel built a basis for the development of novel molecularly stratified treatment approaches. Based on this molecular characterization, an increasing number of specific genomic alterations can potentially serve as treatment targets. Consequently, the development of promising compounds is ongoing. In this review, key molecular alterations in gastric and gastroesophageal junction cancers will be addressed. Finally, the current status of the translation of targeted therapy towards clinical applications will be reviewed.

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.
