Leiomyosarcoma is a malignant mesenchymal tumor originating from smooth muscle cells, which most frequently develops in the myometrium and in the gastro-intestinal tract. Reviewing the international literature, radiation-induced sarcoma arise in 0.035 to 0.2% of all irradiated patients. Especially in the head and neck region, radiation-induced leiomyosarcoma is an extremely rare lesion. The aut...
BACKGROUND Radiotherapy associated with chemotherapy is a well-established treatment modality for locally advanced non-small cell lung cancers. Radiation-induced second malignancies, particularly radiation-induced sarcomas, are rare. Some authors reported a recent increase in the incidence of this rare complication, especially because of the improved prognosis and survival of patients after rad...
The present study deals with cytological effects of 2-mercaptoethyl amine on the Yoshida-sarcoma, the MTK-sarcoma III and Ehrlich ascites tumor concentrating a special attention on cell growth of tumor. 2-Mercaptoethylamine exerts influence upon tumor cells in process of mitosis, especially on an increase of mitotic cells, leading to increase of prophasic cells at first and metaphasic cells sec...
Radiation modulates both tumor cells and immune cells in the tumor microenvironment to exert its anti-tumor activity; however, the molecular connection between tumor cells and immune cells that mediates radiation-exerted tumor suppression activity in the tumor microenvironment is largely unknown. We report here that radiation induces rapid activation of the p65/p50 and p50/p50 NF-κB complexes i...
