These data demonstrate the feasibility of prospective multicentric studies in Africa. An improvement of quality of care has been noticed during the 3 first years.

Introduction Nutritional assessment is an essential component of the initial assessment of children with cancer. Malnutrition may be present at diagnosis due to the effects of the malignancy or, in low income countries (LIC), due to poverty and an inadequate diet. Purpose The aim of this study is to evaluate the prevalence of malnutrition at diagnosis in children with cancer in Morocco. Procedure Nutritional status of 100 children aged less than 18 years with newly diagnosed malignancy between January 2005 and January 2006 was evaluated by anthropometric and biochemical parameters before initiating therapy. We measured weight, height, weight-for-height using z-scores index for children and body mass index for adolescents, triceps skinfold thickness and mid-upper arm circumference, and serum albumin. Results A total of 100 patients were included. The mean age was 7 years (range 1 to 18 years). Sixty percent were boys. The diagnosis was: Burkitt lymphoma (n=19), acute myeloblastic leukaemia (n=18), acute lymphoblastic leukaemia (n=14), rhabdomyosarcoma (n=13), Ewing sarcoma (n=7), nephroblastoma (n=6), Hodgkin disease (n=5), osteosarcoma (n=5), retinoblastoma (n=4), neuroblastoma (n=3), germ cell tumor (n=3), orbital lymphoma (n=1), cerebral lymphoma (n=1), ependymoma (n=1). Incidence of malnutrition ranged from 20–50%, depending upon the measurement used. Conclusion The prevalence of malnutrition in this study was high, so interventions are being implemented to improve the nutritional status of these patients.

These results are encouraging for a developing country but special efforts should be done to reduce the rate of abandonment.

Extramedullary plasmacytoma (EMP) is an uncommon plasma cell neoplasm results from plasma cell proliferation and consists of monoclonal plasmacytic infiltration, without bone marrow involvement and any other systemic characteristics of multiple myeloma. EMP accounts for 3% of all plasma cell neoplasms and approximately 80% to 90% of EMP involve submucosa of the upper aerodigestive, while scrotal, dermis and retroperitoneal infiltration are very rare. There are no consensus guidelines for treatment, but EMP is highly radiosensitive, surgery may be considered for some sites, but 11 at 30% can progress in multiple myeloma. We report here an exceptional case of recurrent EMP in much localization. It's about a man 72 years old with initially testicular plasmocytoma who generalized the plasmacytic infiltration after 16 months in skin and progressively in mediastinal and retroperitoneal plasmacytoma, without any medullar and bone involvement.

Chronic myeloid leukemia (CML), as most of cancers results from a complex interaction between genetic or non genetic factors. Exposures to xenobiotics endogenous or exogenous associated with a reduced individual ability in detoxifying activity, constitutes a risk of developing cancer. It is known that polymorphism of glutathione S-transferases (GSTs) genes affects the detoxification of xenobiotics. Thus, we conducted a case-control study in which 92 patients (Mean age ± SD, 40.62 ± 12.7 years) with CML and 93 healthy unrelated controls (Mean age ± SD, 41.38 ± 13.4 years) have participated. GSTM1 and GSTT1 genotypes were determined by multiplex polymerase chain reaction. Logistic regression was used to assess the possible link between GSTM1 and GSTT1 null genotypes and CML as well as between combined genotypes and CML. GSTM1 null genotype frequency was slightly higher in patients than control (48.9% vs. 40.9%) but, it was not associated with CML (OR 95% CI, 1.4, 0.78-2.48; p = 0.271). Moreover, GSTT1 null genotype frequency showed a similar trend between patients and control (17.4% vs. 9.7%; OR 95% CI, 1.97, 0.82-4.71; p = 0.13). Surprisingly, GSTT1 null genotype was significantly associated with the risk of CML in males (OR 95% CI, 5, 1.25-20.1; p = 0.023). The combined GSTM1 present/GSTT1 null genotype was found to have a limited effect against the risk of CML (OR 95% CI, 0.3, 0.08-0.99; p = 0.049). Our findings have shown that GSTT1 null genotype might be a risk factor of CML in males. While, GSTT1 present genotype might be considered as protective against CML. However, further studies with a large sample size are needed to confirm our findings.
