Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Treatment: Drugs - Carboplatin
Treatment: Drugs - Etoposide
Treatment: Other - Radiotherapy

Experimental: Arm A - Conventional radical radiotherapy in this trial means that those patients with microscopic disease receive a dose of 50Gy using daily incremental fractions of 2Gy over 25 fractions and those with macroscopic disease receive 54Gy in 27 fractions.


Treatment: Drugs: Carboplatin
During radiotherapy: Carboplatin (AUC2) commences on day 1 of radiation and is repeated at weekly intervals on days 8, 15, 22 and 29 (of radiation).
After radiotherapy: 3 weeks after completing radiotherapy, 3 cycles of 3 weekly carboplatin (AUC4.5) intravenously on day 1.

Treatment: Drugs: Etoposide
After Radiotherapy: 3 weeks after completing the radiation therapy, 3 cycles of 3 weekly etoposide (80mg/M2/day) intravenously days 1-3

Treatment: Other: Radiotherapy
Microscopic Disease: 50Gy delivered in 2Gy doses over 25 fractions
Macroscopic Disease: 54Gy delivered in 2Gy doses over 27 fractions

Summary
Brief summary
A Phase II Study designed to evaluate the efficacy of Chemo-Radiotherapy in achieving
loco-regional control in patients with Merkel Cell Carcinoma (MCC) of the skin. Patients will
undergo PET scans to assist in staging and planning the patient's treatment as well as
assessing response at the conclusion of treatment.
