PURPOSEnTo determine the efficacy and tolerability of combining oxaliplatin with capecitabine in the treatment of advanced nonpretreated and pretreated colorectal cancer.nnnPATIENTS AND METHODSnForty-three nonpretreated patients and 26 patients who had experienced one fluoropyrimidine-containing regimen for advanced colorectal cancer were treated with oxaliplatin 130 mg/m(2) on day 1 and capecitabine 1,250 mg/m(2) bid on days 1 to 14 every 3 weeks. Patients with good performance status (World Health Organization grade 0 to 1) were accrued onto two nonrandomized parallel arms of a phase II study.nnnRESULTSnThe objective response rate was 49% (95% confidence interval [CI], 33% to 65%) for nonpretreated and 15% (95% CI, 4% to 35%) for pretreated patients. The main toxicity of this combination was diarrhea, which occurred at grade 3 or 4 in 35% of the nonpretreated and 50% of the pretreated patients. Grade 3 or 4 sensory neuropathy, including laryngopharyngeal dysesthesia, occurred in 16% of patients on both cohorts. Capecitabine dose reductions were necessary in 26% of the nonpretreated and 45% of the pretreated patients in the second treatment cycle. The median overall survival was 17.1 months and 11.5 months, respectively.nnnCONCLUSIONnCombining capecitabine and oxaliplatin yields promising activity in advanced colorectal cancer. The main toxicity is diarrhea, which is manageable with appropriate dose reductions. On the basis of our toxicity experience, we recommend use of capecitabine in combination with oxaliplatin 130 mg/m(2) at an initial dose of 1,250 mg/m(2) bid in nonpretreated patients and at a dose of 1,000 mg/m(2) bid in pretreated patients.

Introduction Le role de la chimiotherapie dans les cancers gastriques avances ou en rechute demeure controverse. Plusieurs molecules et differentes associations ont ete evaluees, mais tres souvent avec de faibles effectifs limitant la portee des conclusions des essais. Le projet GASTRIC est une meta-analyse d’essais basee sur les donnees individuelles de patients en situation avancee, ayant pour but de quantifier le benefice potentiel de differents schemas de chimiotherapies incluant des fluoropyrimidines, des antracyclines, des sels de platine, des taxanes ou de l’irinotecan. Materiels et Methodes Tous les essais cliniques randomises, clos avant fin 2004, ont ete inclus. Les essais neo-adjuvants ou adjuvants ont ete exclus. L’objectif principal etait la survie globale (SG), et l’objectif secondaire la survie sans progression (progression ou deces). Une analyse en intention de traiter a ete realisee en utilisant le test logrank stratifie sur l’essai et le hazard ratio (HR) correspondant. Le benefice absolu a ete estime a partir du HR et du taux de survie a 6 mois dans le bras de reference. Le recueil des donnees a debute en janvier 2007. Resultats Quarante et un essais randomises eligibles (7 225 patients) ont ete identifies. A ce jour, les donnees individuelles des patients de 18 essais (3 226 patients) etaient disponibles pour la SG avec un suivi median de 8,1 mois. Les caracteristiques des patients etaient : âge median 58 ans, etat general OMS 0-1 86 %, metastatiques/localement avances 85 %/15 %, chirurgie avant traitement 53 %. La SG ne differait pas significativement entre les schemas a base d’anthracyclines versus les autres chimiotherapies (7 essais ; 1 501 patients ; HRxa0=xa01,03 ; 95 % ICxa0=xa00,91 - 1,17) ; pxa0=xa00,66), entre les schemas a base d’irinotecan versus les autres chimiotherapies (4 essais ; 670 patients ; HRxa0=xa00,89 ; 95 % ICxa0=xa00,76 - 1,05) ; pxa0=xa00,16), entre les schemas a base de taxanes versus les autres chimiotherapies (3 essais ; 572 patients ; HRxa0=xa00,91, 95 % ICxa0=xa00,76 - 1,08 ; pxa0=xa00,26) ou entre les schemas a base de sels de platine versus les autres chimiotherapies (7 essais ; 1 677 patients ; HRxa0=xa00,99 ; pxa0=xa00,84). Une heterogeneite significative etait detectee dans la derniere comparaison (pxa0 Conclusion Les meta-analyses basees sur les donnees individuelles des patients representent un des plus hauts niveaux de preuve. Nos resultats, bases sur une analyse partielle, ne demontrent pas de superiorite de l’un des schemas en termes de SG. Les medianes de survie demeurent inferieures a 10 mois. Le nombre important de chimiotherapies evaluees pourrait augmenter l’heterogeneite et diluer ainsi un effet potentiel.
