RESUMO
Imatinib mesylate, showed encouraging activity in chronic myelogenous leukemia. However, there are few data regarding his efficacy and response monitoring in Sub-Saharan African patients. Our objective was to assess response to imatinib mesylate (Glivec) in Côte d'Ivoire patients with newly diagnosed Chronic Myeloid Leukemia (CML). From May 2005 to September 2009, we treated 42 patients (40 years; range 16-69) with Philadelphia chromosome (Ph+) positive in chronic phase CML with oral imatinib mesylate at daily doses of 400 mg. Overall survival (OS) and frequency of complete or major cytogenetic remission (CCR/MCR) were evaluated. At a median follow up of 32 (range 7.6-113) months, the CHR rate in our study group was 76%. A major CR was found in 19 patients (45%) with 17% and 29% complete and partial CR respectively. There were no significant differences in the incidence of major cytogenetic response by known prognostics factors. Median time to CHR was 8 months (range 0.4-25), and 16 months (range: 0.1-36) for CR. Projected 5-year OS rate was 72% (95%CI 42-88). We conclude that imatinib therapy sub-Saharan African CML patients is very promising and has favorably changed the prognosis for black African patients with CML.
RESUMO
It acts of a retrospective study relating to 74 patients reached of chronic Leukaemia myeloid (LMC) over one 5 year period followed in the clinical service of hematology of the University Hospital of Yopougon (Abidjan, Ivory Coast). The splenomegaly is quasi-constant in chronic phase of the disease often associated hepatomegaly in 20.27% of the cases which constitutes a pejorative factor of the LMC. Indeed, the hyperleukocytosis of more than 300,000 white globules is correlated with the presence of hepatomegaly (p=0.0005) with risks of portal hypertension. 80% of the patients carrying the LMC with a clinical hepatomegaly in chronic phase of the disease have against an incomplete hematologic remission 20% of complete remission (P = 0.002) among patients without hepatomegaly. The strong rate of death (73.33%) recorded occurred among patients carrying a hepatomegaly against 15.25% of death without hepatomegaly (P = 0.0001). The overall rates Total survival is on average 17 months against 20 months 28 days in the event of absence of the hepatomegaly (P = 0.0001).

Objectif : a l'instar des parametres pronostiques du score de Sokal; l'hepatomegalie dans la leucemie myeloide chronique est-elle un facteur pronostic ? Methode : Il s'agit d'une etude retrospective portant sur 74 patients atteints de Leucemie myeloide chronique (LMC) en phase chronique sur une periode de 5 ans suivis dans le service d' hemato-logie. A l'aide des dossiers medicaux des patients inclus dans notre etude; nous avons recueilli les donnees epidemiologiques; cliniques et biologiques et therapeutiques. Nous avons analyse l'influence de l'hepatomegalie sur la reponse therapeutique; et la survie globale des patients. . Le calcul de la survie s'est fait selon la methode de Kaplan-Meir en tenant compte du facteur pronostique l'hepatomegalie Resultats : La splenomegalie est quasi-constante en phase chronique de la maladie souvent associee a une l'hepatomegalie dans 20;27. L'hyperleucocytose de plus de 300.000 globules blancs est correlee a la presence d'une l'hepatomegalie (p=0.0005) avec des risques d'hypertension portale. Les patients porteurs d'une hepatomegalie ont 20de remission complete hematologique (P = 0;002); un fort taux de deces (73;33) (P = 0;0001) et une survie globale est en moyenne de 17 mois (P = 0;0001). Conclusion : L'hepatomegalie peut etre consideree comme un facteur pejoratif chez les patients porteurs d'une leucemie myeloide chronique en phase chronique du noir africain
