Low Fat Diet to Prevent Disease Progression in Patients With Skin Cancer

Non-Melanomatous Skin Cancer

RATIONALE: A low-fat, balanced diet may prevent disease progression in patients with nonmelanomatous skin cancer. PURPOSE: Randomized phase II trial to study the effectiveness of a low-fat, balanced diet to prevent disease progression in patients with nonmelanomatous skin cancer.

Helping Children be Safe Outdoors With Sun Protection

Sun SensitivitySun Protection1 more

Childhood exposure to high levels of sunlight is a strong determinant of melanoma risk. Pediatric clinicians can provide important sun protection counseling. In 2003, the United States Preventive Services Task Force determined that clinician counseling has an effect on use of sunscreen for children but not for other sun protection measures such as protective clothing, or reducing sun exposure. Regular sunscreen use prevents melanoma development in adults as well as nevi in children, but reliance on sunscreen as the only form of sun protection is problematic. This novel research seeks to develop a sun protection program that is feasible for pediatric clinicians to deliver with patient-centered messages and systems to support program implementation in the clinical offices. The sun protection messages will enable behavioral change by the stakeholders (caregivers and children) that will reduce painful sunburns in the children and eventually reduce the incidence of melanoma. Testing the feasibility of delivering the intervention in a pediatric practice will enhance the sustainability of the intervention, and lead the way to dissemination of good practice. This proposal seeks to develop and test an intervention that seeks to improve sun protection of young children. The intervention includes two phases: Phase 1: From June to August 2014, a voucher to obtain a swim shirt for sun protection provided by the Pediatric Sun Protection Foundation will be affixed to the anticipatory guidance sheet provided by the practice to caregivers of children 2-6 years of age. Phase 2: Analysis of online redemption of vouchers in comparison with the self-reported surveys We hypothesize that redemption of the vouchers will be associated with the perception of the child having sun sensitive skin.

Spanish Registry of Mohs Surgery

Skin NeoplasmsCarcinoma9 more

REGESMOHS (Registro Español de cirugía de Mohs) aims at describing effectiveness of Mohs surgery, and patient, tumor and technique factors related to adverse events and tumor recurrence. REGESMOHS is a prospective cohort, including all patients considered for Mohs surgery in participating centers. All consecutive patients are included. The only exclusion criteria are being under 18-years-old or legally incompetent. Pre-planned follow-up is as required by common clinical practice, but at least once a year for the study period.

Hydrochlorothiazide and Risk of Skin Cancer

Non-melanoma Skin CancerMelanoma1 more

The purpose of this study is to determine whether the use of hydrochlorothiazide is associated with an increased risk of skin cancer compared with the use of angiotensin-converting enzyme (ACE) inhibitors. More specifically, the investigators will assess the risk of non-melanoma and melanoma skin cancer. The investigators hypothesize that the use of hydrochlorothiazide is associated with an increased risk of skin cancer compared with ACE inhibitors. The investigators will carry out separate population-based cohort studies using administrative health databases from seven Canadian provinces and the United States. The study cohort will be defined by the initiation of hydrochlorothiazide or an ACE inhibitor, with follow-up until an incident diagnosis of non-melanoma or melanoma skin cancer. The results from the separate sites will be combined to provide an overall assessment of the risk of non-melanoma and melanoma skin cancer in users of hydrochlorothiazide.

Cancer Mortality Affected by the Choice of Anesthetic Drugs?

Breast CancerColo-rectal Cancer1 more

Knowledge gap: Does the choice of anaesthetic affect outcome for cancer surgery? Aim: To retrospectively examine possible associations (Cox Multiple Regression) between survival from breast-, colorectal-, or skin cancer and the choice of hypnotic used during surgery, ahead of a prospective randomised controlled trial. Hypotheses: One- and five-year survival will be significantly higher after radical breast-, colorectal-, or skin cancer surgery in patients given the intravenously administered hypnotic propofol than in patients given the inhalational hypnotic sevoflurane. Method: To merge two registers, of which one holds demographic- anaesthetic-, and surgical data from 6 303 patients operated on at the three mentioned anatomical locations at the Central Hospital in Vasteras, Sweden during a twelve year period (1998-2009). Of these minimum 4 500 operations would be due to cancer. This register is unique, in that it contains both types of anaesthesia. The other register holds survival data (date and cause of death), stored at the Regional Oncologic Center in Uppsala. The choice of anaesthetic will be validated by controlling each patient's anaesthetic paper file, concomitantly with extraction of details from anaesthesia and surgery, such as the functional classification of each patient (according to American Association of Anesthesiologists), co-morbidity, duration of anaesthesia and surgery, amount of blood loss and possible transfusion. Current knowledge: Different anaesthetics have opposite effects on the immune system and on the DNA. There is a well-established association between the state of the immune system and cancer growth, which in turn will influence survival. There is also an association between DNA damage and cancer development. Inhalational anaesthetics, e.g. sevoflurane, act pro-inflammatory, and they are also proven to be genotoxic. Propofol is anti-inflammatory and anti-oxidative, and it is not genotoxic. Objective: Strengthen the hypotheses, and get statistics for a proper power calculation in advance of a multi-centre, prospective, randomised, controlled trial. Impact: General anaesthesia is an indispensable part of radical cancer surgery. Undesired effects from anaesthesia on survival has strong relevance for the over all cancer treatment.

Use of Traditional Curved Iris Scissors or the Wuennenberg Modified Curved Iris Scissors for Skin...

Skin Cancer

Every year thousands of dermatologic surgery procedures are performed at the University of Missouri Department of Dermatology, including Mohs Micrographic Surgery (MMS), Excisions, and biopsies. Surgery is known to cause anxiety for patients and with these procedures performed under local anesthetic on awake patients', the sights, sounds, and smells experienced during the procedure can lead to an increase in their anxiety or affect their overall perception of the experience. From performing and assisting with dermatologic surgery the noise associated with the use of the traditional curved Iris scissors provokes an increase in patient awareness to the procedure resulting in increased anxiety, triggering of the vasovagal response, and expressions of annoyance by the patient. However, the modified curved Iris scissors make almost no noise. The Investigators hypothesize that if patients were given the comparative experience of both types of curved Iris scissors during dermatologic surgery, then they will choose the modified curved Iris scissors because the lack of noise will be perceived as more pleasant experience. Our objective is to perform a prospective, single blinded, randomized controlled trial to determine how the noise of traditional curved Iris scissors vs the silent Wuennenberg modified curved Iris scissors affects patients during dermatologic surgery.
