Whole-body controlled hyperthermia (up to 43.5 degrees C) of Wistar rats with Walker-256 carcinosarcoma was followed by symptoms of enhanced lipid peroxidation for 3-14 days and release of lysosomal enzymes into blood on day 14. Our data, in totality, point to a potential to stimulate tumor cell
We report a patient with esophageal carcinosarcoma who initially presented with fever. A 57-year-old man with a 4-month history of intermittent fever was referred to our hospital and diagnosed as having esophageal carcinosarcoma. High fever persisted and serum concentration of interleukin-6 was
Hyperglycemia has been shown to decrease tumor pH and blood flow rates, consequently this could increase the sensitivity of tumor to hyperthermia. Combined waterbath hyperthermia (43 degrees C/2 h) and hyperglycemia (6 g/kg, i.p.) was investigated on survival of rats bearing a metastasizing form of
Hyperthermia (temperatures less than 42 degrees C) is widely used in the treatment of cancer. Current thrust in this field is directed towards using agents which can potentiate the effects of hyperthermia. Combined local hyperthermia (43 degrees C/2 hours) and hyperglycemia (6g glucose/kg body
The abscopal effect has previously been described in various tumors and is associated with radiation therapy and hyperthermia, with possible underlying mechanisms explaining each observed case. In the present study, we aimed to investigate the antitumor effects of magnet-mediated hyperthermia on
We studied the main biological characteristics of spontaneous growth of Walker 256 carcinosarcoma and under conditions of antitumor therapy. A combination of whole-body hyperthermia and cytostatic treatment (cyclophosphamide and melatonin) produced maximum suppression of the tumor growth, inhibition
A 51-year-old man visited our hospital with a main complaint of precordial pain, difficulty swallowing, and pyrexia. The patient was diagnosed with esophageal carcinosarcoma, based on the characteristic morphology noted on upper gastrointestinal endoscopy and histology tests, and he underwent
The time course of changes in the content of lipid-soluble antioxidants in the sera of male Wistar rats with transplantable Walker-256 carcinosarcoma in the application of controlled systemic hyperthermia, cyclophosphan, and melatonin were studied. When controlled systemic hyperthermia and
The effects of hyperthermia on vascular permeability in Walker carcinosarcomas and host liver tissue were studied in Sprague-Dawley rats. A quantitative Evans blue technique was used to measure permeability. With tumors heated to 40 degrees C, a nontherapeutic level, no changes in tumor vascular
The authors have studied the effects of La3+ during hyperthermia on tumor cells, Trypan blue exclusion and 86Rb release from previously labeled Ehrlich and DS carcinosarcoma ascites cells, indicate an increase of plasma membrane permeability by La3+ as a function of the hyperthermic level. The
Both squamous cell carcinoma and carcinosarcoma of the renal pelvis are uncommon. We report on two cases, one carcinosarcoma and one squamous cell carcinoma of the renal pelvis. In the patient with squamous cell carcinoma of the left kidney, the tumor was neither detectable on preoperative
OBJECTIVE
Carcinosarcomas of the ovary are rare; hence, although most patients recur after surgical resection or have metastatic disease at the time of diagnosis, only anecdotal information is available concerning the activity of cytotoxic drugs against these lesions. The Gynecologic Oncology Group
Neurofibromatosis or von Recklinghausen's disease is the most common inherited syndrome predisposing to neoplasia. Carcinosarcoma is a rare malignant mixed tumor of the lung. Association of carcinosarcoma of lung with Neurofibromatosis-1 is not common. A 57-year-old man presented with history of
Background: Carcinosarcoma (spindle cell carcinoma) of the esophagus is an extremely rare event; the etiology and origins of this neoplasm have not yet been determined. Epithelial-mesenchymal transition (EMT) has been associated with
