PURPOSE: Basal cell carcinoma (BCC) is a very common cancer in the Caucasian population. Treatment aims to eradicate the tumor with the lowest possible functional and aesthetic impact. Electronic brachytherapy (EBT) is a treatment technique currently emerging. This...

Head and Neck Nonmelanoma Skin Cancer Treated by Orthovoltage Radiation: An Analysis of 1021 Cases
To report a single-institutional experience with the use of orthovoltage radiation for head and neck non-melanoma cutaneous skin cancer (basal cell carcinoma - BCC, squamous cell carcinoma - SCC, and non-invasive squamous cell carcinoma - SCC in situ) and to compare...
Skin Cancers of the Head and Neck: A 21-Year Single-Institution Experience
Skin cancer of the head and neck comprise a heterogeneous mix of tumors with differing treatment response and outcomes depending upon histology. We present a large retrospective analysis of these tumors treated in a single institution over a 21-year period. We present...
Hypofractionated High-Dose-Rate Brachytherapy in Nonmelanoma Skin Cancer Treatment
PURPOSE: Nonmelanoma skin cancer (NMSC) is the commonest cancer in humans. NMSC treatment currently includes surgery, radiation therapy, and topical approaches. The objective was to analyze and compare the outcomes, toxicity, and cosmesis of NMSC treated by two...
Dietary and sex-specific factors regulate hypothalamic neurogenesis in young adult mice.
The hypothalamus is the central regulator of a broad range of homeostatic and instinctive physiological processes, such as the sleep-wake cycle, food intake, and sexually dimorphic behaviors. These behaviors can be modified by various environmental and physiological cues, although the molecular and cellular mechanisms that mediate these effects remain poorly understood. Recently, it has become clear that both the juvenile and adult hypothalamus exhibit ongoing neurogenesis, which serve to modify homeostatic neural circuitry. In this report, we share new findings on the contributions of sex-specific and dietary factors to regulating neurogenesis in the hypothalamic mediobasal hypothalamus, a recently identified neurogenic niche. We report that high fat diet (HFD) selectively activates neurogenesis in the median eminence (ME) of young adult female but not male mice, and that focal irradiation of the ME in HFD-fed mice reduces weight gain in females but not males. These results suggest that some physiological effects of high fat diet are mediated by the stimulation of ME neurogenesis in a sexually dimorphic manner. We discuss these results in the context of recent advances in understanding the cellular and molecular mechanisms that regulate neurogenesis in postnatal and adult hypothalamus.

Predictors of recurrence after radiotherapy for non-melanoma skin cancer
Predictive factors of recurrence were examined in 448 non-melanoma skin cancers (72% basal cell carcinoma, 28% squamous cell carcinoma) treated with radiotherapy. The overall recurrence rate was 15.8% at a median follow-up of 18.4 months. In multivariate analysis,...
Evidence-based treatment for low-risk basal cell carcinoma
Basal-cell carcinoma is the most common cancer worldwide, with more than 2 million lesions treated in the USA in 2006.1,2 In the UK, many basal-cell carcinomas are not registered, which greatly underestimates the numbers of individuals affected.3 Incidence is...
Orthovoltage radiotherapy in the management of medial canthal basal cell carcinoma
AIMS: To report the local control and complication rates of orthovoltage radiotherapy in the management of medial canthal basal cell carcinoma (BCC). METHODS: The medical records of all patients treated with medial canthal BCC between 1998 and 2010, with orthovoltage...
Clinical variants, stages, and management of basal cell carcinoma
Basal cell carcinoma (BCC) is the most common paraneoplastic disease among human neoplasms. The tumor affects mainly photoexposed areas, most often in the head and seldom appears on genitalia and perigenital region. BCC progresses slowly and metastases are found in...
