Cisplatin-based chemotherapy in advanced basal and squamous cell carcinomas of the skin: results in 28 patients including 13 patients receiving multimodality therapy.
This study reports the results of cisplatin (CDDP)-based chemotherapy (CT) as sole therapy and as neoadjuvant (NA) therapy in 28 consecutive patients (pts) with advanced basal cell (BC) and squamous cell (SC) cancers of the skin. CT in 24 pts consisted of CDDP 75 mgm/m2 and doxorubicin (Dox) 50 mg/m2 intravenously (IV) every 3 weeks with Dox being omitted in four pts due to severe preexisting cardiac disease. Thirteen of the 28 pts received CT in the NA setting, five before surgery and eight before radiation therapy (RT). Response rates to CT were complete remission (CR) in eight of 28 (28%) pts, partial remission (PR) in 11 of 28 (40%) for an overall response rate of 68%. Thirteen pts received a second treatment modality with five of 13 pts having a CR to CT alone before the second modality and seven converting to CR postsecond modality for a total CR rate of 12 of 13 (92%) in the multimodality group. Duration of responses in the CT-only group ranged from 4 to 82 months; however, only two patients remain in remission in this group. Of the twelve CRs from the multimodality therapy group, 11 of 12 (91%) pts remain in CR with duration of response ranging from 3 to 81 months. Toxicities were manageable, with no toxic deaths and only five pts stopped CT secondary to side effects. This study suggests the combination of CDDP and Dox is highly effective in BC and SC cancers of the skin and by itself can produce long unmaintained remissions, but when combined with a second modality of therapy, it is capable of producing not only long unmaintained CRs but probable cures in the majority of pts.
