Use of low-dose combined therapy with gemcitabine and paclitaxel for advanced urothelial cancer patients with resistance to cisplatin-containing therapy: a retrospective analysis
Purpose The prognosis of patients with advanced and recurrent urothelial cancer (UC) is poor. Although cisplatin (CDDP)-containing chemotherapy is the most effective regimen in these patients, there is no other established chemotherapeutic regimen. We administered combination therapy with low-dose gemcitabine (GEM) and paclitaxel (PTX), named low-dose gemcitabine-paclitaxel (LD-GP) therapy, as salvage therapy for these patients. The aim was to evaluate the anti-tumoral effects, relief of pain, and toxicity of LD-GP therapy in patients with resistance to CDDP-containing therapy. Patients and methods Thirty-five patients with advanced UC, previously treated with CDDP-containing regimens, were treated with LD-GP therapy (GEM, 700 mg/m 2 + PTX, 70 mg/m 2 on day 1 and 8, repeated every 28 days). Pain was measured on a visual analog scale before and after treatment. Pain relief and survival were compared between this and other treatment regimens. Results None of the patients had complete response to LD-GP therapy. Partial response and stable disease were seen in 25.7 and 62.9 % of patients, respectively. Kaplan- Meier curves showed better survival in patients with LDGP therapy than with others (p = 0.034). Twenty-eight patients (80.0 %) had adequate pain relief, and only two patients needed to increase their analgesics. Other regimens demonstrated pain relief in 30.4 % of patients. Common toxicities included leukopenia, with five patients requiring granular colony-stimulating factor therapy (14.3 %). The most common non-hematologic toxicity was fatigue (n = 7, 17.1 %). Conclusions LD-GP therapy is feasible and well tolerated as salvage therapy in patients with advanced UC with resistance to CDDP-containing therapy
