Randomized phase III trial in elderly patients comparing LV5FU2 with or without irinotecan for first-line treatment of metastatic colorectal cancer (FFCD 2001-02).

BACKGROUND: Metastatic colorectal cancer (mCRC) frequently occurs in elderly patients. However, data from a geriatric tailored randomized trial about tolerance to and the efficacy of doublet chemotherapy (CT) with irinotecan in the elderly are lacking. The benefit of first-line CT intensification remains an issue in elderly patients. PATIENTS AND METHODS: Elderly patients (75+) with previously untreated mCRC were randomly assigned in a 2 × 2 factorial design (four arms) to receive 5-FU (5-fluorouracil)-based CT, either alone (FU: LV5FU2 or simplified LV5FU2) or in combination with irinotecan [IRI: LV5FU2-irinotecan or simplified LV5FU2-irinotecan (FOLFIRI)]. The CLASSIC arm was defined as LV5FU2 or LV5FU2-irinotecan and the SIMPLIFIED arm as simplified LV5FU2 or FOLFIRI. The primary end point was progression-free survival (PFS). Secondary end points were overall survival (OS), safety and objective response rate (ORR). RESULTS: From June 2003 to May 2010, 71 patients were randomly assigned to LV5FU2, 71 to simplified LV5FU2, 70 to LV5FU2-irinotecan and 70 to FOLFIRI. The median age was 80 years (range 75-92 years). No significant difference was observed for the median PFS: FU 5.2 months versus IRI 7.3 months, hazard ratio (HR) = 0.84 (0.66-1.07), P = 0.15 and CLASSIC 6.5 months versus SIMPLIFIED 6.0 months, HR = 0.85 (0.67-1.09), P = 0.19. The ORR was superior in IRI (P = 0.0003): FU 21.1% versus IRI 41.7% and in CLASSIC (P = 0.04): CLASSIC 37.1% versus SIMPLIFIED 25.6%. Median OS was 14.2 months in FU versus 13.3 months in IRI, HR = 0.96 (0.75-1.24) and 15.2 months in CLASSIC versus 11.4 months in SIMPLIFIED, HR = 0.71 (0.55-0.92). More patients presented grade 3-4 toxicities in IRI (52.2% versus 76.3%). CONCLUSION: In this elderly population, adding irinotecan to an infusional 5-FU-based CT did not significantly increase either PFS or OS. Classic LV5FU2 was associated with an improved OS compared with simplified LV5FU2. CLINICALTRIALSGOV: NCT00303771.

[Contribution of endorectal ultrasonography in preoperative evaluation for very low rectal cancer]. / Apport de l'échographie endorectale dans le bilan préopératoire des cancers du très bas rectum.

UNLABELLED: Abdominoperineal resection is the standard treatment of very low rectal carcinoma. Pretherapeutic evaluation of locoregional extension relies mainly on digital rectal examination. The interest of endorectal ultrasonography to assess lateral and inferior margins is still to be determined. AIM OF THE STUDY: To assess the ability of endorectal ultrasonography to evaluate the possibility of conservative anal sphincter surgery. PATIENTS AND METHODS: Between April 1996 and June 1998, 34 patients (20 men, 14 women, mean age: 61 years, range: 43-80) have been treated for rectal adenocarcinoma. Endorectal ultrasonography was made with a linear probe (EUP-U33). Before treatment, the mean distance between the lower pole of the tumor and the anal verge was 3.9 cm (range: 2-5), and between the lower pole and the puborectalis sling 2.3 mm (range: 0-7). A uTN classification was made. Preoperative treatment was radiotherapy (40 Gy in 4 patients, 60 Gy in 24 patients), or radiochemotherapy (6 patients). Pre- and post-radiotherapy endorectal ultrasonography results were compared to the patholocical analysis of operative specimen. RESULTS: Wall infiltration was correctly evaluated in 57% of patients after radiotherapy. In 26/34 cases, a safe plane existed before and after radiotherapy, and correlation of endorectal ultrasonography with histology was 96%. For patients without safe plane, correlation with histology was 75%. CONCLUSION: For very low rectal tumors, with an aggressive sphincter conservation approach, endorectal ultrasonography allows to assess sphincter invasion with 96% fiability when safe plane exists.

[Measurement of the quality of life in chronic hepatitis C: validation of a general index and specific index. First French results]. / Mesure de la qualité de vie chez les malades ayant une hépatite chronique virale C: validation d'un indicateur général et d'un indicateur spécifique.

OBJECTIVES: To report the validation of 2 questionnaires of quality of life in chronic hepatitis C and the first results in 100 patients. METHODS: The questionnaire included 118 items and took 30 to 45 minutes to answer. It included a general index, the Nottingham Health Profile, with 38 items in 6 themes (physical mobility, social isolation, emotional reactions, pain, sleep and energy) and a specific index, the Montpellier Specific Index, with 80 items in 7 themes: symptoms, food, alcohol and tobacco, work, relations with other people, perception of disease. RESULTS: The questionnaires were self-administered to the 100 first patients with chronic hepatitis C without cirrhosis before treatment; 55 men, 45 women, average age 40 year-old, median Knodell's score 8 and median METAVIR score A2 F1. Reduction in the quality of life was frequent and was not highly correlated with biological, virological and histological parameters; it was associated with psychological disorders, reduced sexuality and apprehension of the future. CONCLUSION: This study showed the feasibility, validation, sensitivity and agreement of a quality of life questionnaire, which included a general index and a specific index of chronic hepatitis C in France. These initial results must be confirmed in studies during antiviral treatment of patients.
