A huge rectosigmoidal cancer which extended into the urinary bladder in a 64-year-old man is herein described. The tumor occupied the pelvic and lower abdominal cavities, while the rectosigmoid was totally obstructed. No hepatic or pulmonary metastasis was evident. The ventral and flank sides of the peritoneum in the right lower abdomen, right common iliac vessels, bilateral ureters, terminal ileum, cecum, ascending colon, and urinary bladder were all directly invaded by the tumor, but the aorta, sacrum, and lower rectum were free of cancer. Consequently, an anterior pelvic exenteration was carried out along with an ileal conduit and a right hemicolectomy. Immediately after the exenteration, intra-pelvic hyperthermochemotherapy was performed using a 46–47°C perfusate containing 40 g/ml of mitomycin C (MMC) and 200 g/ml of cisplatin (CDDP), for 90 min, in an attempt to prevent any further local recurrence. A right hemicolectomy and a permanent colostomy were done simultaneously with the hyperthermia treatment. After an uneventful postoperative course, the patient was prescribed adjuvant chemotherapy, i.e., two administrations of 17 mg/m2 and 21 mg/m2 of MMC, and ten doses of 710 mg/m2 of 5-fluorouracil (5-FU) followed by five doses of 535 mg/m2 of 5-FU. At the time of this writing, the patient is still alive without recurrence at 21 months after surgery. 相似文献

A genetic analysis of amphetamine-induced hyperthermia was conducted in inbred mice of the strains Balb/c and C3H and in their F1F2 and backcross generations. The results of biometric analysis indicate that the effect of amphetamine on body temperature is genetically determined. The mode of inheritance characterized by a partial dominance (Balb/C over C3H strain). However, a possible matermal effect of C3H can overcome the dominant effect in male progenies and inhibit amphetamine hyperthermic effect. 相似文献

Summary The effects of intraventricular administration of dibutyryl adenosine 3, 5-cyclic monophosphate (db cyclic AMP) on the thermoregulatory responses of unanesthetized rats and rabbits to different ambient temperatures (Ta) were assessed. Administration of db cyclic AMP (10–60 mM) produced dose-dependent hypothermia in both rats and rabbits at Ta 2–22 °C. The hypothermia in response to db cyclic AMP was due to decreased metabolic heat production and cutaneous vasodilatation. There was no change in respiratory evaporative heat loss. In contrast, in the heat (30–32 °C), db cyclic AMP administration produced dose-dependent hyperthermia in these animals. The hyperthermia was due to increased metabolism (due to muscular shivering) and decreased heat losses. The reduction in heat losses was shown by a decrease in both cutaneous circulation and respiratory evaporative heat loss. The data demonstrate that the thermoregulatory responses induced by central administration of db cyclic AMP are Ta-dependent. 相似文献

BACKGROUND: Patients with cervical cancer who develop pelvic recurrence after primary surgery are usually treated with radiation-based therapy. However, their prognoses are dismal. We conducted a phase I study of combined radiation, hyperthermia and intra-arterial (IA) carboplatin for local recurrence of cervical cancer. PATIENTS AND METHODS: Patients with local recurrence of cervical cancer without extrapelvic recurrence were included in this study. Carboplatin was given as a 5-min IA infusion without hydration just before pelvic radiation every day. External pelvic irradiation (1.8 Gy/day for 28 days) was performed according to local standard schedules. After 20 Gy had been administered, hyperthermia was performed once a week with a radio frequency heating system for four cycles. RESULTS: Fifteen patients were entered through the four dose levels of carboplatin. The maximum tolerated dose was determined to be 25 mg/m(2 )and the dose-limiting toxicities were leukocytopenia, neutrocytopenia and diarrhea. Grade 3/4 leukocytopenia and diarrhea were observed in nine (60%) and three (20%) of 15 patients. Tumor responses included five complete responses and nine partial responses, and the overall response rate was 93.3% (14 of 15) (95% confidence interval 59.4% to 100%). Tumor reductions were observed only at 20 Gy in 10 cases of 14 responders (71.4%). CONCLUSION: The combination therapy of radiation, hyperthermia and IA carboplatin is safe and well-tolerated for locally recurrent cervical cancer. 相似文献

Malignant gliomas have been associated with a high rate of glycolytic activity which is believed necessary to sustain cellular function and integrity. Since lonidamine (LND) is believed to reduce tumor glucose utilization by inhibition of the mitochondrially-bound glycolytic enzyme hexokinase (HK), 31P magnetic resonance spectroscopy (MRS) was used to noninvasively follow the effects of LND on both tumor pH and the high-energy phosphate metabolites; ATP, phosphocreatine (PCr) and inorganic phosphate (Pi) in subcutaneous rat 9L gliosarcomas. 31P tumor spectra acquired in 5 min intervals pre- and post LND administration of 50 and 100 mg/kg, i.p. revealed an acidotic pH shift of – 0.25 and – 0.45 pH units, respectively within 30 min post administration. The ATP/Pi ratio of 9L tumors decreased to 40% of control and Pi levels increased to 280% of control over a 3 hr period. LND exerted no effect on tumor blood flow and mean arterial blood pressure. Brain and muscle metabolite levels and pH were also unaffected by LND. In vitro measurements of cultured 9L tumor cell intra- and extracellular lactate, pentose phosphate pathway (PPP) and hexokinase (HK) activities suggest that the mode of action of LND involves inhibition of lactate efflux and intracellular acidification. The selective reduction of tumor energy metabolites and pH by LND may be exploitable for sensitizing gliomas to radiation, chemotherapy or hyperthermia. 相似文献
