OBJECTIVE
The current study examines the effect of fever-range hyperthermia and mild hypothermia on human cancer cells focusing on cell viability, proliferation and HSP90 expression.
METHODS
A549 and H1299 lung carcinoma, MCF7 breast adenocarcinoma, U87MG and T98G glioblastoma, DU145 and PC3
The feasibility of combining local heat treatment with whole-body hypothermia in an effort to improve therapeutic gain was assessed. Superficial, nonperfused phantom tumors were fashioned in eight anesthetized mongrel dogs by transplantation of the spleen from the abdomen to a subcutaneous site on
OBJECTIVE
It was our aim to review our surgical experience with retroperitoneal tumors extending to the vena cava by using cardiopulmonary bypass, deep hypothermia and circulatory arrest.
METHODS
We performed this procedure in 15 patients. The ages ranged between 16 and 70 years. The primary
Due to the considerable progress made by instrumental total body diagnostics (ECO, CAT, RMN, angiography, etc.) in recent years heart surgery has increasingly often been used to treat pathologies which are not primarily cardiac but which see the involvement of the heart and large vessels in the
The authors report a case of right renal carcinoma with a supradiaphragmatic vena cava thrombus. The patient presented to the emergency ward with a severe pulmonary embolus managed by fibrinolytic treatment. After alcohol embolization of the tumor, the patient underwent a right radical nephrectomy
BACKGROUND
Resistance to cancer metastasis is mediated by host immunity, and mild perioperative hypothermia impairs immune function. We tested the hypothesis that mild perioperative hypothermia increases the risk of cancer recurrence and subsequent mortality
METHODS
In a 5- to 9-year follow-up of
BACKGROUND
Surgical treatment of retroperitoneal tumors with cavoatrial involvement can be challenging. Completeness of resection of the cava tumor extension is crucial for the patient's survival. We report a monocentric experience with the use of cardiopulmonary bypass and deep hypothermic low flow
The by-pass technique with controlled cardiac arrest and hypothermia is probably the best method for an extirpation of intracava tumoral thrombi in renal tumours. The technique is easy to perform, represents a great help in the extirpation of thrombi regardless their size and location, and avoids
The risk of fatal hemorrhage may limit the completeness of resection in hepatic malignancies and in vascular extensions of Wilms' tumors. We have used Ein's technique of deep hypothermia (average 17 degrees C) with cardiac arrest (average 39 minutes) and exsanguination in performing five hepatic and
The present study was designed to investigate the role of macrophages and circulating tumor necrosis factor-alpha (TNF-alpha) in the endotoxin-induced hypothermic responses in rats. Intravenous as well as intraperitoneal administration of endotoxin to male Wistar rats (0.5 mg/kg) led to increased
BACKGROUND
Recent work has shown that intraoperative hypothermia is a significant source of surgical trauma, with wide-ranging physiological and immunological sequelae. The aim of this study was to examine the effects of intraperitoneal hypothermia during laparoscopy on tumor growth in an animal
To evaluate the safety and feasibility of modest hypothermia as a potential strategy for intraoperative neuroprotection during the removal of intradural spinal tumors. A retrospective review was performed for two groups of patients of a single surgeon who underwent intradural extrameduallary and
BACKGROUND
Clinical studies have implicated surgery in promoting infections and compromising immune functions, including natural killer cell activity. Animal studies indicate that surgery-induced suppression of natural killer cell activity also promotes tumor metastasis. Hypothermia, a common
The paper is based on the authors' personal experience in the employment of general and craniocerebral hypothermia in 90 patients operated on for brain tumours. The most rational level of hypothermia is that of 30-31 degrees C body temperature. Craniocerebral hypothermia induced by the "Holod-2F"
Microenvironment has been increasingly recognized as a critical regulator of cancer progression. In this study, we identified early changes in the microenvironment that contribute to malignant progression. Exposure of human bronchial epithelial cells (BEAS-2B) to methylnitrosourea (MNU) caused a
