Surgical excision versus topical 5% 5-fluorouracil and photodynamic therapy in treatment of Bowen's disease: A multicenter randomized controlled trial.

Background: Randomized controlled trials comparing the effectiveness of 5-fluorouracil cream, methylaminolevulinate photodynamic therapy (MAL-PDT) and surgical excision in patients with Bowen's disease are lacking.

Methods: In this multicenter noninferiority trial, patients with a histologically proven Bowen's disease of 4-40 mm were randomly assigned to excision with 5 mm margin, 5% 5-fluorouracil cream twice daily for 4 weeks, or 2 sessions of MAL-PDT with 1 week interval. The primary outcome was the proportion of patients with sustained clearance at 12 months after treatment.

Effectiveness of a patient decision aid for patients with superficial basal cell carcinoma: A pre- and post-implementation study.

Objective: This study evaluates whether using a patient decision aid (PDA) for patients with superficial basal-cell carcinoma (sBCC) results in a decreased decisional conflict level and increased knowledge.

Methods: In a prospective multicentre study, patient groups were included before and after implementation of a PDA. Decisional conflict levels were compared directly after making the treatment decision, measured once as the mean score on the decisional conflict scale (DCS).

Risk of Invasive Cutaneous Squamous Cell Carcinoma After Different Treatments for Actinic Keratosis: A Secondary Analysis of a Randomized Clinical Trial.

Importance: Treatment of actinic keratosis (AK) aims to prevent cutaneous squamous cell carcinoma (cSCC). However, whether AK can progress into invasive cSCC is a matter of debate, and little is known about the effect of treatment on preventing cSCC.

Objectives: To evaluate the risk of invasive cSCC and factors that may contribute to increased risk in patients with multiple AKs.

Surgery versus combined treatment with curettage and imiquimod for nodular basal cell carcinoma: One-year results of a noninferiority, randomized, controlled trial.

Purpose: Nodular basal cell carcinoma (nBCC) is mostly treated with surgical excision. Interest in minimally invasive treatment of these low-risk tumors is increasing. We assessed the effectiveness of nBCC treatment with curettage and imiquimod cream compared with surgical excision.
