What this trial studies

This phase II trial evaluates the effectiveness of EMLA topical cream in alleviating pain for patients undergoing Technetium 99 injections as part of a lymphoscintigraphy procedure for skin cancers. Participants are randomized into two groups: one receiving EMLA cream and the other receiving a placebo, both applied 30 minutes prior to the procedure. The study aims to determine if EMLA can significantly reduce the pain associated with the injections, which are necessary for identifying lymph nodes affected by cancer. This is the first investigation of EMLA cream's efficacy in this specific context, building on previous findings in breast cancer patients.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 to 99 with confirmed diagnoses of cutaneous melanoma, Merkel cell carcinoma, or skin squamous cell carcinoma requiring lymphoscintigraphy.

Not a fit: Patients with known allergies to EMLA cream or local anesthetics, chronic pain conditions, or those who are pregnant may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a more comfortable experience for patients undergoing lymphoscintigraphy for skin cancer.

How similar studies have performed: Previous studies have shown EMLA cream to be effective in reducing pain in other contexts, but this specific application for lymphoscintigraphy is novel.
