RATIONALE: Drugs used in chemotherapy, such as tazarotene, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing.
PURPOSE: This phase II trial is studying topical tazarotene to see how well it works in treating patients with basal cell skin cancer and basal cell nevus syndrome on the face.
|Condition or disease||Intervention/treatment||Phase|
|Neoplastic Syndrome||Drug: tazarotene||Phase 2|
- Determine whether topical tazarotene, administered over a period of 18 months as a chemopreventive agent, reduces the incidence of basal cell carcinomas (BCCs) on treated skin in patients with basal cell nevus syndrome (BCNS).
- Expand and refine chemopreventive strategies in patients with BCNS who are at high risk for the development of BCCs.
OUTLINE: This is an open-label, multicenter study.
Patients apply topical tazarotene cream to the face once daily for 18 months in the absence of unacceptable toxicity.
|Study Type :||Interventional (Clinical Trial)|
|Actual Enrollment :||36 participants|
|Intervention Model:||Single Group Assignment|
|Masking:||None (Open Label)|
|Official Title:||A Phase II Single Arm Open-Label Clinical Trial of Chemotherapy of BCC's With Tazarotene 0.1% in Subjects With Basal Cell Nevus Syndrome|

Tazarotene is a member of the acetylenic class of retinoids.
Other Name: tazorac
- Complete Response Rate [ Time Frame: 36 months ]The primary endpoint used to evaluate tazarotene efficacy for BCC chemotherapy was the complete response (CR) rate, defined as the complete visible disappearance of a patient's "target" lesion during the the 18 months of tazarotene application and its failure to recur during the ensuing 18-months. We defined surgical removal of a target lesion as a treatment failure. The primary endpoint was assessed based on intention to treat analysis such that any subject who underwent the baseline evaluation and applied at least 1 dose of tazarotene was included in the analysis. Drop-outs were considered non-responders. A priori treatment success for tazarotene was defined as a CR rate of at least 50%, and treatment failure was defined as a CR rate of 25% or less.

- Estimated Duration of Complete Response [ Time Frame: 36 months ]
- Overall Response at Treated Lesions [ Time Frame: 36 months ]
