Abstract

Background/aims: We aimed to test clinical implications of intraperitoneally administered gemcitabine and paclitaxel on hepatic regeneration after hepatic resection in rats. Methods: Fifty male, Swiss albino rats weighing between 200 and 240 g were used. After a 30% partial hepatectomy was performed (except Sham group), animals were divided into five groups as: high-dose gemcitabine, low-dose gemcitabine, paclitaxel, control, and Sham operation groups. In the high-dose and low-dose gemcitabine groups, animals received 200 and 12.5 mg/kg intraperitoneal gemcitabine for five days after partial hepatectomy respectively. In the paclitaxel group, animals were administered 6 mg/kg paclitaxel in the same fashion. Control and Sham groups received intraperitoneal 0.9% NaCl. On the sixth postoperative day, the animals were killed liver tissues were resected, proliferating cell nuclear antigen immunopositivity was determined and weight loss and diarrhea were assessed. Results: Gemcitabine and paclitaxel treated animals lost weight and had more severe diarrhea than control and Sham group animals. No significant difference was observed between treatment groups in terms of weight loss, diarrhea, and proliferating cell nuclear antigen. When treatment groups were compared to the control group in terms of proliferating cell nuclear antigen immunopositivity, no significant differences were detected. Conclusions: It can be concluded that adjuvant chemotherapy with gemcitabine and paclitaxel is a safe option in terms of liver regeneration and side effects such as diarrhea and weight loss.

Özet

Amaç: Bu çalışmada hepatik rezeksiyon yapılan farelerde intraperitoneal olarak uygulanan gemsitabin ve paklitakselin hepatik rejenerasyona olan etkileri ve bunun klinik uygulanabilirliği araştırıldı. Metod: Ağırlıkları 200-240 arasında değişen erkek, Swiss albino fareleri kullanıldı. Denekler %30 parsiyel hepatektomi yapıldıktan sonra (sham grubu hariç) yüksek doz gemsitabin, düşük doz gemsitabin, paklitaksel, kontrol ve sham grubu olmak üzere beş gruba bölündü. Parsiyel hepatektomi yapıldıktan sonra, yüksek doz gemsitabin grubundaki farelere 200 mg/kg, düşük doz gemsitabin grubundaki farelere ise 12.5 mg/kg gemsitabin beş gün boyunca intraperitoneal olarak uygulandı. Paklitaksel grubunda farelerede 6 mg/kg paklitaksel intraperitoneal olarak uygulandı. Kontrol ve Sham gruplarına intraperitoneal olarak %0.09 NaCl verildi. Fareler postoperatif 6. gün sakriftye edildi. Karaciğer dokularında PCNA (proliferating cell nuclear antigen) ya bakıldı ve ayrıca kilo kaybı ve diyare gibi semptomlar da kaydedildi. Sonuçlar: Gemsitabin ve paklitaksel verilmiş farelerde, kontrol ve sham gruplarındakilere göre belirgin kilo kaybı ve şiddetli diyare gözlendi. Tedavi grupları arasında kilo kaybı, diyare ve PCNA düzeyleri arasında belirgin farklılık görülmedi. PCNA immunpozitifliği açısından da tedavi grupları ile kontrol grupları karşılaştırıldığında belirgin istatistiksel farklılık saptanmadı. Tartışma: Gemsitabin ve paklitaksel ile yapılan adjuvant kemoterapi karaciğer rejenerasyonu açısından güvenli bir seçenektir fakat diyare ve kilo kaybı gibi yan etkileri vardır.
