RESUMO

Background: In this study, we retrospectively reviewed the treatment outcome of 63 patients with T1 early glottic cancer treated with RT alone to determine the treatment outcome and the prognostic factors affecting local control


Materials and Methods: All patients were treated by 6 MV photons with conventional bilateral fields up to a median dose of 66 Gy in 33 fractions


Results: The 5-year local control rate and overall survival were 77.7% and 93.1%, respectively. The total radiation dose with a cut-off value of 66 Gy was a significant prognostic factor for local control. The 5-year local control rate was 54.5% in patients treated with less than 66 Gy compared to 85.7% in patients treated with 66 Gy or higher dose [p = 0.014]. In subgroup analysis, in patients who received 66 Gy or higher doses, all recurrences developed in whose overall treatment time was 49 days or longer, although the statistical significance was marginal [p = 0.066]


Conclusion: This study showed that a total dose of 66 Gy or higher is required for the treatment of T1 glottic cancer, and delivering the total dose within 49 days seems important for local control

RESUMO

The gold standard for symptomatic relief of bladder outlet obstruction secondary to benign prostatic hyperplasia has traditionally been a transurethral resection of the prostate (TURP). Over the past decade, however, novel laser technologies that rival the conventional TURP have multiplied. As part of the ongoing quest to minimize complications, shorten hospitalization, improve resection time, and most importantly reduce mortality, laser prostatectomy has continually evolved. Today, there are more variations of laser prostatectomy, each with several differing surgical techniques. Although abundant data are available confirming the safety and feasibility of the various laser systems, future randomized-controlled trials will be necessary to verify which technique is superior. In this review, we describe the most common modalities used to perform a laser prostatectomy, mainly, the holmium laser and the potassium-titanyl-phosphate lasers. We also highlight the physical and clinical characteristics of each technology with a review of the most current and highest-quality literature.

RESUMO

Ever since transplant surgery became a common procedure. The early diagnosis of irreversible cessation of cerebral function has become an important need We analysed the findings of transcranial doppler of five cases. Two was diagnosed brain death by currently accepted criteria. Two cases showed absence of intracranial blood flow and normal to disturbed flow status of the cervical carotid artery. Three cases showed reverberating flow pattern with reflux phenomenon. Transcranial doppler investigation seems to provide a practical, non-invasive. And reliable disgnostic evidence for the arrest of cerebral circulation.
