    Comparison of Resection and Liver Transplant in Treatment of Hepatocellular Carcinoma
    (2020) Aksoy, Suleyman Ozkan; Unek, Tarkan; Sevinc, Ali Ibrahim; Arslan, Baha; Sirin, Haluk; Derici, Zekai Serhan; Ellidokuz, Hulya; Sagol, Ozgul; Agalar, Cihan; Astarcioglu, Ibrahim; 0000-0003-4461-4904; 29957158; AAD-6127-2021
    Objectives: Hepatic resection and liver transplant are regarded as 2 potentially curative treatments for hepatocellular carcinoma. Here, we compared both options in patients with hepatocellular carcinoma secondary to cirrhosis seen at a single center over 12 years. Materials and Methods: We evaluated early complications and survival of patients with hepatocellular carcinoma treated with liver transplant (57 patients) or hepatic resection (36 patients) at our center between 1998 and 2010. Results: The 34-month mean follow-up period was similar for both treatment groups. The liver transplant group had a longer hospital stay than the hepatic resection group (P < .001). Patients with Child-Turcotte-Pugh A stage were treated by hepatic resection more than by liver transplant (P < .001), with Child-Turcotte-Pugh B stage patients treated by liver transplant more than by hepatic resection (P = .03). All patients with Child-Turcotte-Pugh C stage had liver transplant. Both treatment groups had similar postoperative complications and early postoperative mortality rates, but liver transplant resulted in longer overall (P = .001) and higher event-free (P = .001) survival than hepatic resection. Among the liver transplant group, 57.8% of patients met the Milan criteria. Patients who met Milan criteria were treated by liver transplant statistically more than hepatic resection, and these patients had longer overall survival (P = .01) and higher event-free survival (P < .001) than patients who had hepatic resection. Hepatocellular carcinoma recurrence rates were higher after hepatic resection (P = .232). Conclusions: In patients with hepatocellular carcinoma, hospital stay was longer after liver transplant, but morbidity and mortality rates for liver transplant versus hepatic resection were similar. However, overall and event-free survival rates were better after liver transplant than after hepatic resection. These results suggest that liver transplant should be considered as the primary treatment option for patients with hepatocellular carcinoma secondary to cirrhosis.

    A Retrospective Evaluation of the Epithelial Changes/Lesions and Neoplasms of the Gallbladder in Turkey and a Review of the Existing Sampling Methods: A Multicentre Study

    Objective: As there is continuing disagreement among the observers on the differential diagnosis between the epithelial changes/lesions and neoplasms of the gallbladder, this multicentre study was planned in order to assess the rate of the epithelial gallbladder lesions in Turkey and to propose microscopy and macroscopy protocols. Material and Method: With the participation of 22 institutions around Turkey that were included in the Hepato-Pancreato-Biliary Study Group, 89,324 cholecystectomy specimens sampled from 2003 to 2016 were retrospectively evaluated. The numbers of adenocarcinomas, dysplasias, intracholecystic neoplasms/adenomas, intestinal metaplasias and reactive atypia were identified with the review of pathology reports and the regional and countrywide incidence rates were presented in percentages. Results: Epithelial changes/lesions were reported in 6% of cholecystectomy materials. Of these epithelial lesions, 7% were reported as adenocarcinoma, 0.9% as high-grade dysplasia, 4% as low-grade dysplasia, 7.8% as reactive/regenerative atypia, 1.7% as neoplastic polyp, and 15.6% as intestinal metaplasia. The remaining lesions (63%) primarily included non-neoplastic polypoids/hyperplastic lesions and antral/pyloric metaplasia. There were also differences between pathology laboratories. Conclusion: The major causes of the difference in reporting these epithelial changes/lesions and neoplasms include the differences related to the institute's oncological surgery frequency, sampling protocols, geographical dissimilarities, and differences in the diagnoses/interpretations of the pathologists. It seems that the diagnosis may change if new sections are taken from the specimen when any epithelial abnormality is seen during microscopic examination of the cholecystectomy materials.
