BACKGROUND While WHO recently recommended universal parasitological confirmation of suspected malaria prior to treatment, debate has continued as to whether wide-scale use of rapid diagnostic tests (RDTs) can achieve this goal. Adherence of health service personnel to RDT results has been poor in some settings, with little impact on anti-malarial drug(More)
SummaryThe variation in the risk of solid second malignant neoplasms (SMN) with time since first cancer during childhood has been previously reported. However, no study has been performed that controls for the distribution of radiation dose and the aggressiveness of past chemotherapy, which could be responsible for the observed temporal variation of the(More)
Objectives and methods.The risk of second primary malignancies (SMN) was studied in a cohort of 4,416 one-year survivors of a breast cancer. The role of the menopausal status and of the initial treatment modalities (surgery, radiotherapy, and chemotherapy) was investigated. Results.Excluding second primary breast cancer and non-melanoma skin cancer, a total(More)
PURPOSE The purpose of this study was to assess the role of treatment in long-term overall and cardiovascular mortality after childhood cancer. PATIENTS AND METHODS We studied 4,122 5-year survivors of a childhood cancer diagnosed before 1986 in France and the United Kingdom. Information on chemotherapy was collected, and the radiation dose delivered to(More)
PURPOSE To provide better estimates of the frequency distribution of second malignant neoplasm (SMN) sites in relation to previous irradiated volumes, and better estimates of the doses delivered to these sites during radiotherapy (RT) of the first malignant neoplasm (FMN). METHODS AND MATERIALS The study focused on 115 patients who developed a solid SMN(More)
Effective case management of malaria requires prompt diagnosis and treatment within 24 hours. Home-based management of malaria (HMM) improves access to treatment for populations with limited access to health facilities. In Senegal, an HMM pilot study in 2008 demonstrated the feasibility of integrated use of RDTs and ACT in remote villages by volunteer Home(More)
Osteosarcoma is the most frequent second primary cancer occurring during the first 20 years following treatment for a solid cancer in childhood. Using a cohort study of children treated for a solid cancer, we investigated the incidence and etiology of osteosarcoma as a second malignant neoplasm after childhood cancer in a cohort and a case-control study. We(More)
Radiotherapy and chemotherapy are associated with an increased risk of a second malignant neoplasm (SMN) after a cancer during childhood. This study specified the dose-effect relationship between radiotherapy, chemotherapy and the risk of a SMN, and investigated the effect of chemo-radiotherapy on the risk of SMN. A case-control study nested in a European(More)
BACKGROUND The thyroid gland is among the most radiosensitive organs. However, little is known about the long-term risk of developing a thyroid tumor after fractionated external radiotherapy for cancer during childhood. OBJECTIVE To study the long-term risk of developing a thyroid tumor in 4096 three-year survivors of childhood cancer treated between May(More)
PURPOSE Cancers of the digestive system constitute a major risk for childhood cancer survivors treated with radiotherapy once they reach adulthood. The aim of this study was to determine therapy-related risk factors for the development of a second malignancy in the digestive organs (SMDO) after a childhood cancer. METHODS AND MATERIALS Among 4,568 2-year(More)
