Abstract: Rhabdomyosarcoma is a rare disease in children and young adults, usually responsive to chemotherapy. Here we report on a patient with chemorefractory disease, treated in an unconventional approach. A young woman presented with an embryonal rhabdomyosarcoma...
Abstract: We report a pitfall deriving from the assumption of metastatic disease based upon seemingly identical histology in a pulmonary lesion and in the esophagus. In a 60-year-old patient, cT1 esophageal squamous cell carcinoma was found. One of the two pulmonary...
Abstract: Loco-regional antiblastic perfusion with circulatory block (stop-flow perfusion, SFP) is a procedure designed to treat solid tumors of the limb and pelvis in an advanced stage, like melanoma, sarcoma of the soft tissues and colon-rectal cancer. The aim of...
Abstract: The objectives of the study were to test the hypothesis that hyperbaric levels of oxygen enhance the sensitivity of a sarcoma cell line to doxorubicin (Adriamycin) both in vitro and in vivo in a rat model of pulmonary metastases and to test the feasibility...
Abstract: Hypoxic tumor cells are an important factor of radioresistance. Hyperbaric oxygen (HBO) and normobaric carbogen (95% oxygen, 5% carbon dioxide) increase the oxygen delivery to tumors. This study was performed to explore changes of tumor oxygenation during a...
Abstract: Hyperbaric oxygen (HBO) has been shown to increase tumor radiosensitivity. Several reports indicate that it also increases sensitivity to alkylating agents, but other reports suggest that it may speed angiogenesis and tumor growth. To throw light on these...
Abstract: Hyperbaric oxygen (HBO2) is used as an adjunct in the treatment of radiation injury at many sites, including the mandible, larynx, chest wall, bladder, and rectum. In these disorders, HBO2 is effective in stimulating neovascularization and reducing fibrosis....
Abstract: In 1982, a 55-year-old woman was treated by total cystectomy and adjuvant radiotherapy/chemotherapy for a leiomyosarcoma of the bladder. Fifteen years later she presented with symptoms and signs of sacral plexopathy. Investigations revealed...
Abstract: The objective of this study was to investigate the incidence of overexpression of TP53 (formerly known as p53) in osteosarcomas occurring after treatment of rabbit mandibles with high-dose external-beam radiation. As part of a protocol investigating...
Abstract: Hypoxic clonogenic cells are an important contributory factor in tumour radioresistance. The objective of the present study was to evaluate whether hyperbaric oxygen enhances tumour radiosensitivity, using a conventionally fractionated irradiation schedule,...
