What's known on the subject? and What does the study add?
Metastatic or locally advanced squamous cell carcinoma of the penis (SCCP) is generally incurable, but it can be palliated with systemic chemotherapy. Two retrospective studies, involving <10 patients each, showed that cisplatin plus continuous infusion of 5-fluorouracil (5-FU) may be effective and well tolerated. Cisplatin, methotrexate and bleomycin, cisplatin and irinotecan and taxanes can also play an important role for patients with locally advanced/metastatic SCCP. Finally, anti-EGFR therapy may also be effective in advanced SCCP.
Although cisplatin plus continuous infusion of 5-FU is widely used in clinical practice for palliation of SCCP, toxicity and efficacy data regarding this schedule include a total of 14 patients with SCCP, treated more than two decades ago. In our retrospective study, cisplatin plus continuous infusion of 5-FU was used for palliative purposes in a homogenous sample of 25 patients with SCCP. Partial responses and stable disease were observed in 8 (32%) and 10 (40%) patients, respectively, with a median progression-free survival of 20 weeks. Neutropenia was the most important grade 3–4 side effect observed, occurring in 20% of patients. These data provide confirmation that such a combination regimen is moderately effective and well tolerated in patients with SCCP.
