BACKGROUND/AIMS To investigate the in vitro effect of a short time exposure to the anthracycline idarubicin on proliferation, protein synthesis, and motility of human Tenon's capsule fibroblasts in comparison with the antitumour antibiotic mitomycin C. METHODS After determination of effective concentrations of idarubicin, fibroblasts of the human Tenon's capsule were exposed to idarubicin or ...

The unpredictable clinical toxicity observed in patients treated with mitomycin C and the observation that this agent must be reduced to an active form before alkylating target molecules have led to the development of a bioassay which is capable of detecting biologically active forms of mitomycin C in the plasma of drug-treated patients. The bioassay makes use of a repair-deficient mutant of Ch...

UNLABELLED This study aimed at describing an alternative surgical technique to the insertion of a ventilation tube in the tympanic membrane: myringotomy by radiofrequency alone and associated with mitomycin C. AIM to show a surgical approach that can be simple to execute, not subject to complications arising from the ventilation tube. MATERIALS AND METHODS we compared myringotomy by microkn...

Thrombotic thrombocytopenic purpura (TTP) is a critical complication of treatment with mitomycin C. We retrospectively describe the case of a patient with progressive renal cell carcinoma and mitomycin-induced TTP refractory to plasma exchange and glucocorticoids; we describe the clinical course, successful management of TTP with rituximab, and follow-up of this case. Mitomycin-induced TTP reso...

purpose : although applying mitomycin c (mmc) during photorefractive keratectomy (prk) has shown to reduce postoperative corneal haze but there is considerable evidence of mmc toxicity in the literature and concerns exist regarding side effects and long-term complications. we conducted this study to compare the efficacy of mmc 0.02% and 0.01% in prevention of haze after prk. methods : 210 eyes ...

Introduction. BRCA1-associated ovarian cancer (OC) is characterized by high sensitivity to DNA-damaging agents, however, the most effective drug therapy regimen not defined. Aim. To compare clinical efficacy of combination «mitomycin C and cisplatin» (MP) «paclitaxel carboplatin» (TCbP) in neoadjuvant BRCA-associated randomized trial. Methods. The study involved 98 patients with advanced cancer...

BACKGROUND Cytoreductive surgery combined with hyperthermic intraperitoneal chemotherapy (CRS/HIPEC) has become a common treatment approach for disseminated appendiceal neoplasms. Systemic absorption of intraperitoneal chemotherapeutics may lead to drug-induced toxicity, most commonly neutropenia. Mitomycin C has been the most commonly used chemotherapeutic in HIPEC for the past several decades...

The lethal actions of mitomycin C and actinomycin D were followed during the division cycle of HeLa cells. The cells were most susceptible to a 2 hr pulse of mitomycin C during the G(1) phase, whereas their sensitivity to actinomycin D was most pronounced in the S phase. Posttreatment of the cells with acetoxycycloheximide, a potent inhibitor of protein synthesis, increased the survival (colony...
