The primary objective of this study is to (1) determine whether local injection of lidocaine used during Mohs surgery will elevate serum lidocaine concentrations to a level that could cause systemic symptoms and (2) determine whether sustained high levels of serum lidocaine occur after intralesional anesthesia on the face and neck. This study is a cross-sectional study of 10 subjects with basal cell carcinoma or squamous cell carcinoma of the face or neck requiring Mohs micrographic surgery. The study will consist of a brief questionnaire and blood draws during their Moh's surgical procedure.
This will be a study where all patients will undergo a two-step procedure: Step 1 - Physicians examine the problem area of skin ONLY and record result. Step 2 - Physicians perform TBSE and record result. Eventual lesions suggestive of melanoma and non-melanoma skin cancers will be recorded after step 1 or step 2 examination and will be finally biopsied and histopathologically diagnosed. Exceptions to biopsy may include patients with multiple non-melanoma skin cancers (e.g. actinic keratoses or basal cell carcinomas). Each center will be provided with an electronic data sheet for patients record, or alternatively, with a paper record form. Endpoints of the study are new parameters concerning the standard of care for skin cancer screening. We expect to conclude that TBSE enables clinicians discovering an increased number of skin cancers thus resulting in earlier detection.
RATIONALE: Photodynamic therapy uses a drug that becomes active when it is exposed to a certain kind of light. When the drug is active, tumor cells are killed. This may be an effective treatment against skin cancer. PURPOSE: This phase II trial is studying the side effects of photodynamic therapy using aminolevulinic acid and to see how well it works in treating patients with skin cancer.
Mohs' micrographic surgery (MMS) is a treatment of choice for high recurrence risk basal-cell carcinomas (BCC). Realized under local anaesthesia, it induces very low recurrence rates and spares unnecessary excision of intact surrounding tissues, thus decreasing the needs for flaps, skin grafts, and allows immediate reconstruction…. Its disadvantages are mainly: need for a significant training of the operator, the pathologist and the non-medical personnel; longer duration of the procedure, with higher a priori costs, and constraints for the patient related to the duration of the intervention. Traditional surgical excision with immediate or differed reconstruction is the technique of reference. Provided that re-excisions are performed as long as previous ones do not guarantee free margins, it gives good results. Its real costs are poorly known and can be enhanced by several considerations: multiplicity of the operational acts if the initial excision is insufficient, more complex reconstruction procedures, duration of post-operative dressings, …. The investigators' objective is to know the costs of the surgical treatment of the high risk CBC, comparing the CMM with the surgical excision with immediate or differed reconstruction, along with its effectiveness defined by the absence of recurrence. by its impact on the quality of life of the patient. It is a prospective, multicentric, comparative, not randomized, open, cohort study, of the type "here and elsewhere". Patients with high-risk CBC, as defined by the French ANAES Guidelines (2004), will be included: - clinically morpheaform aspect or ill-limited margins, aggressive histological forms; - already recurred BCC (except for superficial BCCs)); - nodular BCC located in the high-risk zone (nose, peri-orificial areas of the head) and with diameter larger than 1 cm. The effectiveness will be measured by the rate of recurrence at 5 years (as measured by the prolongation of the follow-up after the surgical procedure). The utility from the patient point of view will be evaluated by a specific dermatologic quality of life questionnaire (Skindex) and by a generic questionnaire (Euroqol 5D), supplemented by a questionnaire of satisfaction of the care (Attkisson). The economic perspectives studied will be those of the hospital, of the payer and of the society. Direct medical costs will be evaluated by micro-costing. The main production factors implied in the realization of one CMM or one traditional surgery in dermatology/surgery and anatomopathology wards will be identified, counted, and developed. The measuring units will be the estimate of the time devoted to each individual procedure, reported to the total activity of each ward and the wages of the various categories of personnel implied, and the unit costs in consumable and redeemable material, reported to their utilisation factor. The hospital indirect costs will be estimated by the financial services of the hospitals. Accrual of 150 CMM and 300 traditional excisions will be performed within a two year period of time.
The purpose of this study is to determine the safety of BMS-833923 (XL139) in patients with advanced or metastatic cancers and determine the recommended phase 2 dose range and schedule
This study is an equivalency study designed as a randomized clinical trial. Patients with a biopsy proven nodular periocular basal cell carcinoma (BCC) who have agreed to have surgical excision will be eligible. Study patients will undergo surgical excision of the lesion and then be randomized to having frozen section or permanent section pathological control. For those patients randomized to permanent section control the sample will be sent to pathology and surgical reconstruction will be performed. Patients randomized to frozen section will have additional margins re-excised before reconstruction depending on the pathologic results. Tumor clearance rates after surgical excision will be compared between the two techniques as a primary study question. Patients will be followed long-term to determine recurrence rates in the two groups. The study is designed to determine if the two techniques are equivalent within a given margin of error with respect to outcome measures.
RATIONALE: Chemoprevention is the use of certain drugs to keep cancer from forming. The use of acitretin may stop cancer from growing in patients at high risk for basal cell carcinoma or squamous cell carcinoma of the skin. PURPOSE: This randomized trial is studying how well acitretin works in preventing skin cancer in patients at high risk for skin cancer.
Currently, we conduct a prospective, randomized trial comparing the outcome of surgical excision with the outcome of curettage in nodular and superficial BCCs. Larger BCCs and micronodular or sclerosing BCCs are not included in the randomized study. They are mainly operated using three-dimensional histology (3D-histology, micrographic surgery). In this observational study we measure the cosmetic result and the recurrence rate of all BCCs not included in the randomized trial.
The purpose of this study is to determine the safety and tolerability of pharmaceutical compound (API 31510) topical cream topically applied to superficial basal cell carcinomas to obtain preliminary efficacy data for the treatment of superficial basal cell carcinomas by API 31510 topical cream. The study population will include one hundred and sixty (160) otherwise healthy male or female adults with one or more histologically confirmed superficial basal cell carcinoma lesions. One target lesion with an area of less than one inch will be designated for study treatment.
