Abstract

The toxicity of cisplatin precludes its use in patients with bladder cancer with abnormal renal function tests or poor performance status, thus carboplatin may be used as a substitute. In this study, we evaluated retrospectively the patients treated with neoadjuvant gemcitabine-carboplatin (GCb) in our clinic to assess the efficacy and toxicity of this regimen. Patients with localized muscle invasive bladder cancer were treated with 3 cycles of gemcitabine (1000 mg/m2 days 1, 8 q3w) and carboplatin (AUC= 4 according to the Calvert formula, day 1, q3w) combination and were subsequently operated. Response rates in terms of pathological complete response (pCR) and safety issues were assessed. Fourteen patients were evaluated. Median age of the patients was 62 (range 55-79) and all were males. Median creatinine clearance was 51 ml/min (range 29-72 ml/min). Nine patients completed 3 cycles of chemotherapy while 2 patients received 2 cycles and 3 patients received 1 cycle. The treatment was generally well tolerated. Grade 3/4 neutropenia developed in 4 patients (29%) and grade 3/4 thrombocytopenia developed in 3 patients (21%). One patient developed febrile neutropenia. Afetr surgery, pCR was achieved in one patient (7% of whole group). The median interval between the last dose of neoadjuvant chemotherapy and the time of surgery was 45 days (range 17-106 days) and this interval was significantly correlated with post-operative pathological T stage of the tumor (r= 0.844, p= 0.017). Gemcitabine-carboplatin combination represents a feasible alternative to gemcitabine-cisplatin regimen with moderate activity and favorable toxicity profile. Shorter interval between the completion of chemotherapy and the time of surgery was associated with higher rates of response.

Özet

Mesane kanserli hastalarda böbrek fonksiyonlarındaki bozukluk ya da performans statusunun kötü olması nedeniyle sisplatin kullanımı güç olabilir. Bu hastalarda alternatif olarak karboplatin kullanılabilir. Bu çalışmada kliniğimizde mesane kanseri nedeniyle neoadjuvant gemsitabin-karboplatin (GCb) rejimi ile tedavi edilen hastaları retrospektif olarak inceledik. Kas tabakasına invaze mesane kanseri olan hastalara 3 kür neoadjuvant gemsitabin (1000 mg/m2, 1. ve 8. günler, 21 günde bir) ve karboplatin (AUC= 4 Calvert formülüne göre, 3 haftada bir 1. gün) tedavisi uygulandı ve daha sonra opere edildiler. Patolojik tam yanıt oranları ve güvenlilik parametreleri değerlendirildi. Ondört hastanın verileri incelendi. Ortanca yaş 62 (55-79 aralığında) idi ve tüm hastalar erkekti. Ortanca kreatinin klerensi 51 ml/dk (29-72 ml/dk. aralığında) idi. Dokuz hasta 3 kür, 2 hasta 2 kür ve 3 hasta 1 kür tedavi aldı. Tedavi genellikle iyi tolere edildi. Dört hastada (%29) grad 3/4 nötropeni, 3 hastada (%21) grad 3/4 trombositopeni saptandı. Bir hastada febril nötropeni gelişti ve antibiyotik tedavisi verildi. Cerrahi sonrası 1 hastada (%7) patolojik tam yanıt elde edildi. Kemoterapinin son dozu ile cerrahi arasında geçen ortanca süre 45 gündü (17-106 gün aralığında) ve bu süre ile patolojik T evresi arasında anlamlı ilişki saptandı (r= 0.844, p= 0.017). Gemsitabin-karboplatin tedavisi orta düzeyde etkinlik gösteren ve yan etki profili iyi olan bir tedavi rejimidir ve gemsitabin-sisplatin rejimine alternatif olarak kullanılabilir. Kemoterapinin tamamlanmasından cerrahiye kadar geçen sürenin kısa olması daha iyi yanıt oranları ile ilişkili bulunmuştur.
