Primary cutaneous lymphomas are a heterogeneous group of diseases. They often remain localized, and they generally have a more indolent course and a better prognosis than lymphomas in other locations. They are highly radiosensitive, and radiation therapy is an...
Radiation Therapy
Electronic brachytherapy–current status and future directions.
In the past decade, electronic brachytherapy (EB) has emerged as an attractive modality for the treatment of skin lesions and intraoperative partial breast irradiation, as well as finding wider applications in intracavitary and interstitial sites. These miniature...
Prevalence and costs of skin cancer treatment in the U.S., 2002-2006 and 2007-2011
BACKGROUND: Skin cancer, the most common cancer in the U.S., is a major public health problem. The incidence of nonmelanoma and melanoma skin cancer is increasing; however, little is known about the economic burden of treatment. PURPOSE: To examine trends in the...
Electrons Versus Surface Brachytherapy for Non-Melanoma Skin Cancer – A Matched Pair Analysis
Surgery is the mainstay of treatment for non-melanoma skin cancers (NMSC) unless location or comorbidities mandate noninvasive modalities like radiation. Electrons are commonly used worldwide to treat skin cancers; however, there has been a recent increase in use of...
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...
Clinical implementation of a new electronic brachytherapy system for skin brachytherapy
Although surgery is usually the first-line treatment for nonmelanoma skin cancers, radiotherapy (RT) may be indicated in selected cases. Radiation therapy as primary therapy can result in excellent control rates, cosmetics, and quality of life. Brachytherapy is a...
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.
