Trends in colorectal cancer incidence by anatomic site and disease stage in the United States from 1976 to 2005.
The objectives of the current study were to examine the trends in incidence rates of subsite-specific colorectal cancer at all stages in a large US population and to explore the impact of age and sex on colorectal cancer incidence. ⋯ Overall incidence rate of colorectal cancer decreased over the past 3 decades. The percent of ascending colon and hepatic flexure cancers diagnosed at early stages (localized and regional) increased. The finding on sex difference over years suggests that great attention should be paid in the future studies to male and female disparities.

Analysis of seed loss and pulmonary seed migration in patients treated with virtual needle guidance and robotic seed delivery.
To determine whether automated seed delivery system and real-time intraoperative (IO) virtual needle guidance reduce seed loss and pulmonary seed migration. ⋯ Our pulmonary seed migration and total seed loss rates are comparable to the ones reported in the literature. Virtual needle guidance and automated seed delivery system are in our hand as accurate as the manual technique.

Squamous cell carcinoma of the anal margin: the university of Florida experience.
To update our experience in treating squamous cell carcinoma of the anal margin with definitive radiotherapy (RT). ⋯ Patients with squamous cell carcinoma of the anal margin have a high probability of cure with sphincter preservation after RT with or without concurrent chemotherapy.

Chemoradiation for esophageal cancer: institutional experience with three different regimens.
The aim of this study was to retrospectively evaluate toxicity and efficacy of 3 chemoradiation regimens. ⋯ With individual treatment planning, different regimens of chemoradiation for esophageal cancer resulted in acceptable rates of toxicity and efficacy.

Gamma knife radiosurgery for vestibular schwannomas: tumor control and functional preservation in 70 patients.
We present the previously unreported outcomes of 70 patients treated with Gamma knife radiosurgery for vestibular schwannoma (VS), including comprehensive analysis of clinical outcomes and the effects of lower marginal doses. ⋯ In the treatment of VS, contemporary radiosurgical techniques and the use of marginal doses below 13 Gy offer excellent tumor control, at high rates relative to surgical intervention. These findings are independent of marginal dose and tumor size. Patients should be informed about the benefits and risks of radiosurgery and microsurgery before choosing an intervention. Further analysis of post-treatment outcomes should be encouraged as follow-up times increase and the treatment protocols continue to evolve.
