Subsequent resection of locally advanced pancreatic carcinoma after chemoradiotherapy.

OBJECTIVES: The aim of this study was to evaluate the possibility of subsequent resection of locally advanced pancreatic adenocarcinoma after chemotherapy and external-beam radiotherapy. PATIENTS AND METHODS: Between January 1996 and January 2001, 33 consecutive patients (18 males and 15 women, mean age 63 years) with locally advanced PA were treated with chemotherapy and concurrent external-beam radiotherapy. Radiotherapy delivered 45-50.4 Gy, in a classical manner (N=27) or on a split-course (N=6). Chemotherapy was made of 5FU by continuous infusion for all patients during 5 weeks and cisplatin at the 1st and 5th weeks (N=22). Tumor resectability was reassessed at the end of the chemoradiotherapy; surgical resection of tumour was attempted in patients whose tumor demonstrated reduction in size, and supplementary radiotherapy of 10 to 15 Gy was delivered to the others. RESULTS: Thirty-nine percent of patients experienced grade 3 acute toxicity. WHO criteria response to chemoradiotherapy four weeks after the end of treatment were: 4 partial responders (12%), 6 minor responders (18%), 14 stable disease (42%), 9 progression (28%). Ten patients underwent exploratory laparotomy, in one case vascular encasement did not allow for tumor resection, and in another patient, there was peritoneal carcinomatosis. In the 8 remaining patients, surgical (R0) resection was possible. In one patient histological examination showed fibrosis with no residual tumour. After a median follow-up period of 40 months, median survival was 16 months (66% and 37% of survival at 1 and 2 years respectively). In operated and non-operated patients, survival rates at 24 months were 73% and 12.5% respectively. At 1 year, 80% of the patients treated with radiochemotherapy developed recurrence, metastatic recurrence in 88%. Initial laparotomy, split course radiotherapy were poor outcome factors whereas chemotherapy appears to be a favorable outcome factor. CONCLUSION: Subsequent resection of locally advanced pancreatic adenocarcinoma is possible after chemoradiotherapy allowing for a prolonged survival in some patients.

Value of microsatellite instability typing in detecting hereditary non-polyposis colorectal cancer. A prospective multicentric study by the Association Aquitaine Gastro.

AIM OF THE STUDY: To detect hereditary non-polyposis colorectal cancer (HNPCC) patients with a strategy combining clinical selection (patient age at onset of cancer less than 50 years or family history of HNPCC tumors) and microsatellite instability typing plus immunohistochemistry, leading to mismatch repair (MMR) germline mutation analysis. METHODS: Tumors were screened for microsatellite instability (MSI) and for hmlh1 and hmsh2 immunohistochemical expression. Germline mutation analysis was performed to search for MLH1 and MSH2 mutations in patients with MSI-High and MSI-Low tumors. RESULTS: 197 adenocarcinomas were studied: 164 patients were< or =50 years old, 33 were older than 50 years but had a family history of HNPCC tumors. Fifty tumors (25.4%) were MSI-High, 10 were MSI-Low (5.1%), and 130 were MS-Stable (66%). MSI typing was inconclusive in 7 (3.5%). Immunohistochemistry screening was performed on 165 tumors: sensitivity was 63.6%, specificity was 99%. Germline mutation analysis was performed in 33/60 MSI-High or Low tumors: 23 mutations were noted (70% of the tested patients). CONCLUSION: This proposed strategy of determining microsatellite instability in young colorectal cancer patients or in patients with a family history of HNPCC tumors led to an increased frequency in the detection of MMR germline mutations.

Safety of cisplatin combined with continuous 5-FU versus bolus 5-FU and leucovorin, in metastatic gastrointestinal cancer (FFCD 9404 randomised trial).

BACKGROUND: The objective of this phase III study was to compare the safety and efficacy of FLP (modulation of 5-FU (Fluorouracil) by folinic acid or leucovorin (LV) and cisplatin vs. FP (5-FU combined with Cisplatin) as a first line chemotherapy in advanced oesophageal, gastric and pancreatic cancer. PATIENTS AND METHODS: 232 patients with measurable lesions were randomised to receive at the first cycle either FP (arm A: 5-FU 800 mg/m2/d in continuous infusion 5 days and cisplatin 100 mg/m2 on day 1 or 2), or FLP (arm B: LV, 100 mg/m2/d in bolus 5 days, followed by 5-FU 350 mg/m2/d in 1 h infusion 5 days and cisplatin 100 mg/m2 on day 1 or 2). In case of no grade 3-4 haematological and diarrhoea toxicity, the dose of 5-FU was increased to 1000 mg/m2/d and 400 mg/m2/d in the two arms respectively, for the subsequent cycles until disease progression. RESULTS: The distribution of primary tumours was: 19 squamous cell carcinoma of the oesophagus, 19 oesophageal adenocarcinoma, 91 gastric and 97 pancreatic adenocarcinoma. Safety remained acceptable and comparable in the two arms except for the severe grade 3-4 mucositis, which was lower in arm B (4.5 vs. 16.4%, p < 0.009). Efficacy in terms of tumour response and survival was similar in the two arms, showing an objective response rate (after external review) of 18.6% (95% confidence interval (CI) 11.4-25.8%) in arm A vs. 15% (95% CI 8.5-21.6%) in arm B, an overall median survival of 24 weeks in arm A vs. 24.7 in arm B (p = 0.83) and a progression-free median survival of 12.4 weeks vs. 12.1 in arms A and B, respectively (p = 0.91). CONCLUSION: The FLP regimen is substantially equivalent to FP in terms of safety and quality of life, as well as for antitumour efficacy in these carcinomas; the only slight advantage of FLP in this study concerns mucositis. Based on these results, FLP could be used as an alternative to FP when appropriate.
