InterAACT: A multicentre open label randomised phase II advanced anal cancer trial of cisplatin (CDDP) plus 5-fluorouracil (5-FU) vs carboplatin (C) plus weekly paclitaxel (P) in patients (pts) with inoperable locally recurrent (ILR) or metastatic treatment naïve disease - An International Rare Cancers Initiative (IRCI) trial

Whilst advanced squamous cell carcinoma of the anal canal (SCCA) is a rare disease incidence has risen by 2%/year for the past decade. There is no consensus on management of these pts who generally have a poor overall survival (OS) and to date no randomised trial has been completed. The combination of fluoropyrimidine /platinum agents is often considered standard 1st line therapy whilst taxanes have shown activity. We conducted a randomised phase II study to establish a standard of care.
