Palliative radiation therapy practice for advanced esophageal carcinoma in Africa.

While numerous surveys of pattern of practices of palliative radiotherapy (RT) in advanced esophageal cancers have been published in developed countries, there is no such survey in African countries. During and after a regional training course by the International Atomic Energy Agency (IAEA) in palliative cancer care, a questionnaire was distributed to African RT centers to gather information about infrastructure and human resources available, and the pattern of practice of palliative RT for esophageal cancers. Twenty-four of the 35 centers (60%) completed the questionnaire. Twenty out of 23 (87%) centers treat patients with esophageal cancer presenting with dysphagia using external beam RT (16 centers external beam RT alone and 4 centers also use brachytherapy as a boost). Twelve (60%) centers prescribe RT doses of 30 Gy in 10 fractions and 2 centers 20 Gy in 5 fractions. Eighteen centers (78%) have low dose rate (LDR) brachytherapy, and 9 (39%) centers have high dose rate (HDR) brachytherapy. One center only used HDR brachytherapy alone to a dose of 16 Gy in 2 fractions over 8 days. RT remains a major component of treatment of patients with esophageal cancers in African countries. Still, there is a great variety among centers in both indications for RT and its characteristics for a treatment indication.

Cerebellous metastases in patients with uterine cervical cancer. Two cases reports and review of the literature.

Brain metastases from cervical cancer are extremely rare. We report on two patients who developed cerebellous metastases following uterine cervical cancer. The interval between diagnosis of the primary cancer and diagnosis of brain metastasis was 8 months. The main complaint was symptoms of increased intracranial pressure and cerebellous syndrome. Surgical excision of the brain lesion followed by radiation therapy was performed in the first case. The second patient received palliative radiation therapy. The first patient died 8 months after diagnosis. The second patient is alive 2 months after diagnosis.

Primary testicular lymphoma.

Primary testicular lymphoma (PTL) is a rare disease accounting for 1% of non-Hodgkin's lymphoma. PTL occurs more frequently in older patients and is a potentially fatal disease. In the early stages (I and II), the treatment consists of orchidectomy followed by chemotherapy (CT) and prophylactic scrotal radiotherapy (RT) with/or without iliac and/or paraaortic lymph node RT. In the advanced stages (III and IV), CT is the treatment of choice whereas the place of scrotal RT is controverted. In both early and advanced disease intrathecal CT is warranted to prevent CNS relapse. New molecular approaches and/or more aggressive treatments are being explored.

Radiochemotherapy for lung cancer in developing countries.

Radiochemotherapy has become a standard approach in locally advanced non-small cell lung cancer and limited disease small cell lung cancer. Most of the data supporting this observation come from the developed world and only extremely rarely have good-quality clinical trials been carried out in developing countries. It is therefore of paramount importance to put the experience of the developed world into the context of the limited resources and other health care problems of developing countries. In this overview, the problems with the implementation of such data are discussed. The necessity of carrying out clinical trials specifically designed to address the needs of developing countries is emphasised. The research on cheaper ways of radiochemotherapy combination should be encouraged. The specific national guidelines for local needs should be created and followed. The availability of radiotherapy equipment is of major importance, as radiotherapy has a pivotal role in non-surgical treatment of lung cancer, especially in the developing world.

Chimiotherapie des cancers du col de l'uterus au stade IV a vesical a l'Institut Curie de Dakar

Les cancers du col de l'uterus au stade IV ne relevent plus de la combinaison standard radio-chirurgicale. Aussi dans notre contexte marque par les difficultes de tous ordres pour correctement appliquer la chimiotherapie; nous avons pense opportun de retracer notre experience dans l'utilisation de moyen therapeutique dans les cancers du col uterin classes IVa vesical a Dakar. Sur 91 dossiers retenus; 80 ont concerne la mise en oeuvre de la combinaison chimiotherapie et radio-therapie selon diverses modalites. Les resultats enregistres dans la pratique de cette modalite nous poussent a proposer la procedure chimiotherapie neoadjuvante suivie de radiochimiotherapie dans notre contexte en l'absence de curietherapie pour ameliorer la survie
