Conclusion: Treatment with 5-FU following hepatectomy caused not only suppression but delay of liver cell division.The results indicate that adjuvant chemotherapy with 5-FU after partial hepatectomy should be prescribed with great care or should not be carried out until hepatic regeneration is almost completed.

Abstract

Background/Aims: In this study, the effects of 5-fluorouracil (5-FU) on liver regeneration was studied after two thirds hepatectomy in rats, in vivo. Extensive hepatic resection is performed with increasing frequency for malignant tumors of the liver and administration of chemotherapy immediately after removal of the major tumor is favorable. Methods: Wistar male Albino rats, weighing 150-280 g, underwent hepatectomy under standard conditions. In Group A, 70% hepatectomy alone was performed. In Group B, 5-fluorouracil at a dose of 20 mg/kg was administered intraperitoneally and in Group C, a 30 mg/kg dose of 5-fluorouracil was administered intraperitoneally immediately after 70% hepatectomy. The rats were sacrifized on the 1st, 3rd, 5th and 7th days following hepatectomy. Argyrophilic nucleolar organiser region score, mitotic figure, Kuppfer cell counts and liver function tests were carried out. Results: Administration of 5-fluorouracil caused substantial suppression and delay of liver cell division in a dose dependent manner, especially on the 1st and 3rd day after hepatectomy. The effect of 5-fluorouracil reversed within 24 hours of drug withdrawal and arrested cells at the S phase completed the sequences. Conclusion: Treatment with 5-FU following hepatectomy caused not only suppression but delay of liver cell division.The results indicate that adjuvant chemotherapy with 5-FU after partial hepatectomy should be prescribed with great care or should not be carried out until hepatic regeneration is almost completed.

Özet

Amaç: Bu çalışmada, ratlarda 2/3 hepatektomi sonrası 5-fluorouracil'in karaciğer rejenerasyonuna olan etkisi çalışılmıştır. Karaciğerin malign tümörleri için geniş hepatik rezeksiyonlar günümüzde sıklıkla uygulanmaktadır. ideal olan tümör çıkarıldıktan hemen sonra kemoterapi uygulanmasıdır. Yöntem: Ağırlıkları 150-280 mg arasında değişen Wistar albino ratlarda standart koşullarda hepatektomi yapılmıştır. Grup A'da sadece %70 hepatektomi yapılmıtır. Grup B'de aynı oranda hepatektomiyi takiben intraperitoneal olarak 20 mg/kg 5-fluorouracil uygulanmıştır. Grup C'de ise %70 hepatektomi sonrası 30 mg/kg 5-fluorouracil intraperitoneal uygulanmıştır. Ratlar hepatektomi sonrası 1., 3., 5., 7. günlerde sakrifiye edilmişlerdir. Ag-NOR skoru, mitotik figür, Kuppfer hücre sayısı ve karaciğer fonksiyon testleri çalışılarak rejenerasyon değerlendirilmiştir. Bulgular: 5-Fluorouracil uygulanması özellikle 1. ve 3. günlerde supresyona ve doza bağımlı olarak karaciğer hücre bölünmesinde gecikmeye sebep olmuştur. İlacın metabolize olması ile etkisi 24 saat içinde geri dönmüştür. Hücre siklüsünün S fazında duran hücreler siklüslerini tamamlamışlardır. Sonuç:Parsiyel hepatektomi sonrası 5-FU ile adjuvant kemoterapi uygulamasında dikkatli takip gerekir. Gerekirse kemoterapi uygulaması hepatik rejenerasyon tamamlanıncaya kadar beklenmelidir.
