Clinical TrialPhase I clinical trial of weekly paclitaxel, weekly carboplatin, and concurrent radiotherapy for primary cervical cancer.
Standard primary treatment for locally advanced cervix cancer is radiation (RT) with concomitant platinum-based chemotherapy (CT). Incomplete local control and the appearance of distant disease herald poor survival and warrant evaluation of new primary strategies. Paclitaxel and carboplatin are active agents in recurrent cervical carcinoma, have potent, synergistic in vitro radiosensitization, and are cytotoxic in weekly schedules. This study was done to determine the maximum tolerated dose (MTD) and dose-limiting toxicity (DLT) of weekly paclitaxel/carboplatin chemoradiotherapy in locally advanced cervix cancer. ⋯ Weekly paclitaxel and carboplatin chemoradiation is feasible and active. The MTD for a phase II trial is 50 mg/m(2) and AUC 2.5, respectively.

The value of transvaginal ultrasonography in the prediction of endometrial pathologies in asymptomatic postmenopausal breast cancer tamoxifen-treated patients.
There is no established ultrasonographic endometrial cutoff value for the diagnosis of endometrial pathologies in asymptomatic postmenopausal tamoxifen (TAM)-treated patients. We attempted to seek the most accurate cutoff value. ⋯ In asymptomatic postmenopausal breast cancer tamoxifen-treated patients, the use of wider ultrasonographic endometrial cutoff values could be associated not only with the performance of fewer endometrial samplings, but also with a higher possibility of endometrial pathologies, including endometrial cancers, being left undiagnosed.

Clinical TrialPhase II study of carboplatin and whole body hyperthermia (WBH) in recurrent and metastatic cervical cancer.
Hyperthermia enhances carboplatin cytotoxicity preclinically, and clinical studies have shown radiant heat Whole Body Hyperthermia (WBH) to be safe. In this study, the efficacy and toxicity of the combination of 41.8 degrees C WBH and carboplatin in recurrent and/or metastatic cervical cancer were explored. ⋯ The efficacy of WBH and carboplatin in recurrent and/or metastatic cervical cancer seems comparable to that of other palliative chemotherapy regimens in this disease. The considerable toxicity, though largely manageable, includes unexpected and severe unacceptable renal toxicity. This regimen seems less suitable for palliative care.

Patients with uterine papillary serous cancers may benefit from adjuvant platinum-based chemoradiation.
The coexistence of minimal uterine disease and extrauterine metastases is common in patients with uterine papillary serous carcinoma (UPSC). Only complete surgical staging accurately depicts the extent of this disease. The purpose of this study was to evaluate different therapeutic options in surgically staged patients. ⋯ Our findings suggest that stage IA patients with no residual uterine disease may be observed. Stage IA patients with residual uterine disease may benefit from chemoradiation. More effective treatment needs to be identified for advanced stage UPSC.

Multicenter Study Clinical TrialCarboplatin hypersensitivity: a 6-h 12-step protocol effective in 35 desensitizations in patients with gynecological malignancies and mast cell/IgE-mediated reactions.
The incidence of hypersensitivity reactions (HR) is increased in patients treated with multiple courses of carboplatin. The purposes of this investigation were to evaluate the effectiveness of a 12-step desensitization protocol and to characterize the immune mechanism of carboplatin HR. ⋯ The 6-h, 12-step desensitization protocol is safe and effective for treating patients with carboplatin HR. Positive skin tests to carboplatin suggest a mast cell/IgE-mediated mechanism. Conversion of the positive skin test to a negative response after desensitization supports antigen-specific mast cell desensitization.
