Review Comparative StudyTreatment results of high-dose-rate remote afterloading brachytherapy for cervical cancer and retrospective comparison of two regimens.
To review the treatment results and complications of high-dose-rate (HDR) intracavitary brachytherapy for patients with carcinoma of the cervix in a single institute and to compare them with those of low-dose-rate (LDR) brachytherapy reported in the literature. ⋯ Our experience in treating cervical cancer with HDR intracavitary brachytherapy is encouraging. Our treatment results and complication rates were compatible with those of the LDR series. Further studies are eagerly awaited to better define the optimal fractionation schedule for HDR brachytherapy and the schedule on how chemotherapy may be combined with it.

ReviewOutcome and patterns of failure in pathologic stages I-IV clear-cell carcinoma of the endometrium: implications for adjuvant radiation therapy.
To evaluate the outcome and patterns of failure in women with uterine clear-cell carcinoma and discuss implications for adjuvant radiation therapy (RT). ⋯ Clear-cell carcinoma comprises a small percentage of endometrial cancers, frequently presents as a mixed histology, and has a poor overall outcome. Unlike papillary serous tumors, clear-cell carcinoma does not seem to have a high propensity for abdominal failure. Our results thus do not support the routine use of whole-abdominal RT in these patients. Future protocols should focus instead on combinations of locoregional RT and chemotherapy to reduce the risk of local and systemic recurrence.

ReviewTen-year outcome after combined modality therapy for inflammatory breast cancer.
To evaluate the long-term outcome of combined modality therapy for inflammatory breast cancer. ⋯ The outcomes for patients completing multimodality therapy compare favorably with published data; however, the exclusion of patients with progression during induction chemotherapy may account in part for these results. The pathologic complete response rate was found to be an important prognostic factor. Selected patients with inflammatory breast cancer have the potential for long-term survival.

Clinical TrialA phase I trial of etanidazole and hyperfractionated radiotherapy in children with diffuse brainstem glioma.
To determine the toxicity and maximum tolerated dose of etanidazole administered concurrently with hyperfractionated radiation therapy (HRT) for children with brainstem glioma. ⋯ The MTD of etanidazole in children receiving HRT for brainstem glioma is 42 g/m(2), with cutaneous rash as the dose-limiting toxicity. This is in contrast to the adult experience, which demonstrates a 24% lower MTD of 34 g/m(2) limited by peripheral neuropathy.

Comparative StudyQuantifying the degree of conformity in radiosurgery treatment planning.
To compare different parameters used to quantify the quality of a treatment plan and to evaluate the dose conformity and coverage clinically achieved using gamma knife radiosurgery. ⋯ With gamma knife radiosurgery, it is possible to achieve highly conformal dose distributions. A single parameter for the quantification of a plan, though desirable, is not realistic, because of the competing components of high dose to the target and low dose to normal tissue. Thus, we propose the use of the CI, together with the target volume coverage.
