Background: First-line platinum-based therapy for advanced squamous cell carcinomas of the anal canal (SCCA) implies a risk of substantial side effects, and data on second-line treatment options are limited. Paclitaxel and Capecitabine are a well-known regimen with a moderate toxicity profile, but its efficacy has not been evaluated. Methods: We conducted a retrospective study using Danish Hospital Registers of patients treated with Paclitaxel and Capecitabine for inoperable, recurrent, or advanced metastatic SCCA in Denmark, between January 2000 and July 2018. Results: A total of 52 patients met the eligibility criteria. Median age was 60.7 years (range 42–83). Efficacy was observed, with an overall response rate in patients receiving first-line (N = 28) and second-line (N = 23) Paclitaxel and Capecitabine of 39.3% (2 with complete responses) and 17.4%, respectively. Median progression-free survival (PFS) was 4.5 months (95% CI 3.3–5.9) and 3.8 months (95% CI 2.4–5.5) with OS of 6.7 months (95% CI 5.9–8.5) and 5.9 months (95% CI 3.9–14), respectively. Performance status ≥2 and neutrophil to lymphocyte ratio ≥4 were significantly associated with a short PFS. Conclusion: This study recognizes Paclitaxel and Capecitabine as a potential regimen for advanced SCCA, when recommended first-line therapy is not feasible or as a potential second-line treatment after failure of platinum-based chemotherapy.
