Background: Gastrointestinal cancers are among the top 10 cancers and causes of cancer death worldwide. Given the absence of cancer registry in Madagascar and absence of epidemiological study of gastrointestinal cancer in the province of Fianarantsoa, our aim was to describe the epidemiological aspect of gastrointestinal cancers at the University Hospital of Tambohobe Fianarantsoa.Methods: Authors have conducted a descriptive retrospective study over a three-year period from January 1, 2015 to December 31, 2017 at the University Hospital of Tambohobe Fianarantsoa (in oncology, internal medicine and visceral surgery departments). The variables analyzed were age, gender, tumor location.Results: Authors have collected 74 cases of gastrointestinal cancers. There were 46 males 62.16% and 28 females 37.84%. The mean age was 56.30±12.10 years old. The predominant age groups were 45-55 years. Authors found colorectal cancer in 43%, followed by liver carcinoma in 19%, then pancreatic cancer 14%, esophageal cancer 13%, gastric cancer 8%, duodenum cancer 3%.Conclusions: Gastrointestinal cancers at the hospital of Tambohobe Fianarantsoa affect young people, especially the male gender with a predominance of colorectal and liver cancer.So, it is important to continue the vaccination against hepatitis viral B infection and to implement a colorectal cancer screening program.

Alveolar rhabdomyosarcomas (ARMS) are rare entities that occur predominantly on the extremities and represent 20% of rhabdomyosarcomas. Other common locations include the peri-rectal and perineal regions, head and neck, and genitourinary system. To our knowledge, this presentation is the first case of alveolar rhabdomyosarcoma of the chest wall reported in the literature. Here, we describe a case of a 64-year-old man with alveolar rhabdomyosarcomas who underwent a chest wall resection. The defect was reconstructed with polypropylene mesh and latissimus dorsi muscle. Our patient did not show recurrence ten months after complete resection. The present paper describes our surgical approach to a case of primary alveolar rhabdomyosarcoma of the chest wall in an adult. The authors discuss the principal judgment criteria for successful surgical resection and prognosis, highlighting the relevance of chest wall reconstruction and their complementary aspects in the multimodal management of this rare entity.
