[Locally advanced unresectable pancreatic cancer: Induction chemoradiotherapy followed by maintenance gemcitabine versus gemcitabine alone: Definitive results of the 2000-2001 FFCD/SFRO phase III trial]. / Cancer du pancréas localement évolué non resécable : chimioradiothérapie d'induction suivie de chimiothérapie par gemcitabine contre chimiothérapie exclusive par gemcitabine : résultats définitifs de l'étude de phase III 2000-2001de la FFCD et de la SFRO.

PURPOSE: To compare chemoradiation with systemic chemotherapy to chemotherapy alone in locally advanced pancreatic cancer. PATIENTS AND METHODS: One hundred and nineteen patients with locally advanced pancreatic cancer, with World Health Organization performance status of zero to two were randomly assigned to either the induction chemoradiation group (60 Gy, 2 Gy/fraction; concomitant 5-fluoro-uracil infusion, 300 mg/m(2) per day, days 1-5 for 6 weeks; cisplatin, 20 mg/m(2) per day, days 1-5 during weeks 1 and 5) or the induction gemcitabine group (GEM: 1000 mg/m(2) weekly for 7 weeks). Maintenance gemcitabine (1000 mg/m(2) weekly, 3/4 weeks) was given in both arms until disease progression or toxicity. RESULTS: Overall survival was shorter in the chemoradiation than in the gemcitabine arm (median survival 8.6 [99% confidence interval 7.1-11.4] and 13 months [8,9,9-18], p=0.03). One-year survival was, respectively, 32 and 53%. These results were confirmed in a per-protocol analysis for patients who received 75% or more of the planned dose of radiotherapy. More overall grades 3-4 toxic effects were recorded in the chemoradiation arm, both during induction (36 versus 22%) and maintenance (32 versus 18%). CONCLUSION: This intensive induction schedule of chemoradiation was more toxic and less effective than gemcitabine alone.

Phase III trial comparing intensive induction chemoradiotherapy (60 Gy, infusional 5-FU and intermittent cisplatin) followed by maintenance gemcitabine with gemcitabine alone for locally advanced unresectable pancreatic cancer. Definitive results of the 2000-01 FFCD/SFRO study.

BACKGROUND: The role of chemoradiation with systemic chemotherapy compared with chemotherapy alone in locally advanced pancreatic cancer (LAPC) is uncertain. PATIENTS AND METHODS: One hundred and nineteen patients with LAPC, World Health Organization performance status of zero to two were randomly assigned to either the induction CHRT group (60 Gy, 2 Gy/fraction; concomitant 5-fluorouracil infusion, 300 mg/m(2)/day, days 1-5 for 6 weeks; cisplatin, 20 mg/m(2)/day, days 1-5 during weeks 1 and 5) or the induction gemcitabine group (GEM: 1000 mg/m(2) weekly for 7 weeks). Maintenance gemcitabine (1000 mg/m(2) weekly, 3/4 weeks) was given in both arms until disease progression or toxicity. RESULTS: Overall survival was shorter in the CHRT than in GEM arm [median survival 8.6 (99% confidence interval 7.1-11.4) and 13 months (8.7-18.1), P = 0.03]. One-year survival was, respectively, 32% and 53%. These results were confirmed in a per-protocol analysis for patients who received 75% or more of the planned dose of radiotherapy. More overall grades 3-4 toxic effects were recorded in the CHRT arm, both during induction (36 versus 22%) and maintenance (32 versus 18%). CONCLUSION: This intensive induction schedule of CHRT was more toxic and less effective than gemcitabine alone.

Multicentre randomised phase III trial comparing Tamoxifen alone or with Transarterial Lipiodol Chemoembolisation for unresectable hepatocellular carcinoma in cirrhotic patients (Fédération Francophone de Cancérologie Digestive 9402).

The FFCD 9402 multicentre phase III trial was designed to compare the effects of the combination of Transarterial Lipiodol Chemoembolisation (TACE) and tamoxifen with tamoxifen alone on overall survival and quality of life in the palliative treatment of hepatocellular carcinoma with cirrhosis. From 1995 to 2002, 138 patients were randomised between the two groups. One hundred and twenty three patients were eligible including 61 in the Tamoxifen group and 62 in the TACE group. Baseline characteristics were similar: Child-Pugh class A: 70%, alcoholic cirrhosis: 76%, Okuda stage I: 71%, multinodular tumour: 70% and segmental portal vein thrombosis: 10%. At 2years, the overall survival was 22% and 25% in the Tamoxifen and TACE groups (P=.68), respectively. Multivariate analysis identified four independent prognostic factors for survival: alpha-fetoprotein (AFP)>400ng/mL (P=.008), abdominal pain (P=.011), hepatomegaly (P=.023) and Child-Pugh score (P=.032). The Spitzer Index level assessing the quality of life during follow-up did not differ between the two groups (P=.70). Amongst patients with stage Okuda I, the 2-year overall survival was 28% in the Tamoxifen group and 32% in the TACE group (P=.58). In this subgroup, two prognostic factors were statistically significant for survival: AFP>400ng/mL (P=.004) and Spitzer Index (P=.013) as shown by multivariable analysis. In conclusion, this study suggests that TACE improves neither the survival nor the quality of life in patients with HCC and cirrhosis.

Adjuvant chemotherapy with 5-fluorouracil and cisplatin compared with surgery alone for gastric cancer: 7-year results of the FFCD randomized phase III trial (8801).

BACKGROUND: The aim of this study was to evaluate the efficacy of adjuvant chemotherapy after resection for gastric cancer in a randomized controlled trial. PATIENTS AND METHODS: After curative resection, stage II-III-IVM0 gastric cancer patients were randomly assigned to postoperative chemotherapy or surgery alone. 5-Fluorouracil (5-FU) 800 mg/m(2) daily (5-day continuous infusion) was initiated before day 14 after resection. One month later, four 5-day cycles of 5-FU (1 g/m(2) per day) plus cisplatin (100 mg/m(2) on day 2) were administered every 4 weeks. RESULTS: The study was closed prematurely after enrollment of 260 patients (79.7% N+), owing to poor accrual. At 97.8 months median follow-up, 5- and 7-year overall survival were 41.9% and 34.9% in the control group versus 46.6% and 44.6% in the chemotherapy group (P=0.22). Cox model hazard ratios were 0.74 [95% confidence interval (CI) 0.54-1.02; P=0.063] for death and 0.70 (95% CI 0.51-0.97; P=0.032) for recurrence. An invaded/removed lymph nodes ratio >0.3 was the main independent poor prognostic factor identified by multivariate analysis (P=0.0001). Because of toxicity, only 48.8% of patients received more than 80% of the planned dose. CONCLUSION: There was no statistically significant survival benefit with this toxic cisplatin-based adjuvant chemotherapy, but a risk reduction in recurrence was observed.

Assessment of tumour response to chemotherapy for metastatic colorectal cancer: accuracy of the RECIST criteria.

Evaluation of tumour size modifications in response to treatment is a critical issue in the management of advanced malignancies. In 1981, the World Health Organization (WHO) established guidelines for tumour response assessment. These WHO1981 criteria were recently simplified in a revised version, named RECIST (Response Evaluation Criteria in Solid Tumours), which uses unidimensional instead of bidimensional measurements, a reduced number of measured lesions, withdrawal of the progression criteria based on isolated increase of a single lesion, and different shrinkage threshold for definitions of tumour response and progression. In order to validate these new guidelines, we have compared results obtained with both classifications in a prospective series of 91 patients receiving chemotherapy for metastatic colorectal cancer. Data from iterative tomographic measurements were fully recorded and reviewed by an expert panel. The overall response and progression rates according to the WHO1981 criteria were 19% and 58%, respectively. Using RECIST criteria, 16 patients were reclassified in a more favourable subgroup, the overall response rate being 28% and the progression rate 45% (non-weighted kappa concordance test 0.72). When isolated increase of a single measurable lesion is not taken into account for progression with the WHO1981 criteria, only 7 patients were reclassified and the kappa test was satisfying, i.e. > or =0.75, for the whole population as well as for each of the responding and progressive subgroups. Since it provides concordant results with a simplified method, the use of RECIST criteria is recommended for evaluation of treatment efficacy in clinical trials and routine practice.
