ABSTRACT
Objective:To investigate the clinical efficacy of laparoscopic eversion fixation of cyst wall in the treatment of simple hepatic cyst.Methods:The clinical data of 27 patients with simple hepatic cyst who underwent laparoscopic cyst eversion fixation in Department of Hepatobiliary Surgery, the First Affiliated Hospital of Henan University of Science and Technology from January 2017 to December 2020 were retrospectively analyzed. There were 8 males and 19 females, aged (60.6±9.0) years. Methods of operation, operation time, pathological results, incisional pain, peritonitis, bleeding or infection in the sac were analyzed. Recurrence was followed up by outpatient or telephone review.Results:Laparoscopic eversion fixation of cyst wall was successfully performed in all patients. Twelve cases (44.4%) were fixed in the falciform ligament, and 15 cases (55.6%) were fixed on the liver surface. The operative time was (119.3±44.3) min. The histopathologic results of the capsular wall were all fibrous connective tissue coated with endothelial cells, and no tumor cells were found. After the operation, 25 cases (92.6%) of light clear cyst fluid were not cultured for bacteriology, and 2 cases (7.4%) of turbid cyst fluid bacteriology culture was negative. There were 11 cases (40.7%) with right upper abdominal incision pain on the first day after surgery, and the pain disappeared after proper treatment without bile leakage, peritonitis, bleeding or infection. All patients were followed up for 18 to 36 months, with a median follow-up time of 24 months, and no cyst recurrence was reported.Conclusion:Laparoscopic eversion fixation of cyst wall is a good method for the treatment of simple hepatic cyst.
ABSTRACT
Objective:To analyze the expression of LC3-Ⅱ and ATF3 in hepatocellular carcinoma (HCC) , to explore the relationship between their expression and the prognosis of patients with HCC, and to analyze the expression correlation betweenLC3-Ⅱ and ATF3 in HCC tissues.Methods:Immunohistochemical method was used to detect the expression of LC3-Ⅱ and ATF3 protein in HCC tissue and corresponding paracancerous tissue specimens, to analyze the relationship between these two proteins and the patient's clinicopathological characteristics as well as survival time. Western blot was used to detect the expression of LC3-Ⅱ and ATF3 proteins in fresh HCC tissues and corresponding paracancerous tissue.Results:The expression of LC3-Ⅱ and ATF3 inparacancerous tissues was significantly higher than that in HCC tissues. The expression levels of were related to HCC histopathological grade and venous tumor thrombus (all P<0.05), but were not related to age, gender, and serum alpha-fetoprotein, tumor diameter, HBsAg, etc (all P>0.05) . The low expression of LC3-Ⅱ and ATF3 was significantly related to the poor prognosis of patients with HCC (both P<0.05). Conclusions:Both LC3-Ⅱ and ATF3 protein expression are related to the occurrence and development of HCC. The combined detection of LC3-Ⅱ and ATF3 is helpful for the assessment of the malignant degree of HCC and it is expected to become an important indicator for judging the prognosis of patients.
ABSTRACT
BACKGROUND AND OBJECTIVES: The prognostic prediction for centrally located hepatocellular carcinoma (CL-HCC) after hepatectomy has not been well established. We aimed to develop prognostic nomograms for patients undergoing hepatectomy for CL-HCC. METHODS: A cohort of 380 patients who underwent curative hepatectomy for CL-HCC at our hospital between 2009 and 2015 were retrospectively studied. We randomly divided the subjects into training (n = 210) and validation (n = 170) groups. Univariate and multivariate survival analysis were used to identify prognostic factors. Visually orientated nomograms were constructed using Cox proportional hazards models. The performance of the nomogram was evaluated by the area under the ROC curve (AUC), calibration curve and compared with the conventional staging systems. RESULTS: The statistical nomogram for OS built on the basis of ALBI grade, tumor number, tumor size, classification, hepatectomy methods, capsule formation and microvascular invasion (MVI) had good calibration and discriminatory abilities, with AUC of 0.746 (65-month survival). The nomogram for DFS was based on tumor number, tumor size, classification, HBV-DNA load, capsule formation and MVI, with AUC of 0.733 (65-month survival). These nomograms showed satisfactory performance in the validation cohort (AUC, 0.733 for 65-month OS; and 0.702 for 65-month DFS). The AUC of our nomograms were greater than those of conventional staging systems in the validation cohort. CONCLUSION: The established nomograms might be useful for estimating survival for patients with CL-HCC after liver resection.
