Comparison of Postoperative Hemorrhage Risk After Partial Liver Transplantation Versus Whole Liver Transplantation: A Single-Center Experience.

BACKGROUND: We aimed to identify risk factors associated with reoperation for postoperative intraperitoneal hemorrhage (PIH) after orthotopic liver transplantation and investigate if partial liver transplantation (PLT) increases the risk of PIH. METHODS: We retrospectively analyzed the medical records of 304 consecutive recipients who underwent orthotopic liver transplantation at the Affiliated Lihuili Hospital, Ningbo University, from January 2016 to July 2022. Data were compared between recipients who experienced PIH requiring reoperation and those who did not. Subgroup propensity score matching analysis was performed to assess the impact of PLT on PIH risk. Neither prisoners nor participants who were coerced or paid were used in the study. RESULTS: Among the 304 recipients, 22 (7.2%) underwent reoperation for PIH. Multivariate analysis revealed that the recipient Model for End-Stage Liver Disease (MELD) score (odds ratio = 1.066, 95% CI [1.025-1.109], P = .001) and volume of intraoperative packed red blood cell transfusion (odds ratio = 1.089, 95% CI [1.032-1.481], P = .002) were independent risk factors for PIH. No significant differences were observed in the risk of PIH between PLT and whole liver transplantation. CONCLUSION: Preoperative MELD score and intraoperative packed red blood cell transfusion should be carefully considered to manage the risk of PIH in liver transplantation recipients. Partial liver transplantation, a crucial approach for addressing donor shortages, does not increase the risk of reoperation for PIH in recipients.

Surgical Treatment of Postoperative Abdominal Metastases of Hepatocellular Carcinoma: 10-Year Experience in a Single Center.

OBJECTIVE: The significance of surgical treatment was analyzed by retrospectively collecting data on the re-resection of intra-abdominal metastases after hepatocellular carcinoma (HCC) surgery in our center over the past 10 years. METHODS: The clinical and pathological data of 15 patients who developed intra-abdominal metastases after HCC resection and underwent re-resection from January 2010 to January 2020 were collected to analyze the patients' characteristics and prognosis. RESULTS: Of the 15 cases of abdominal metastasis, the majority (8 cases) had greater omental metastasis. There were 4 cases of mesenteric metastases, 1 case of abdominal wall metastasis, 1 case of mesenteric plus rectal wall metastasis, and 1 case of colon and mesenteric metastasis. The 1-year, 3-year, and 5-year disease-free survival (DFS) rates were 31.1%, 23.3%, and 11.7%, respectively. The 1-year, 3-year, and 5-year overall survival rates were 93.3%, 28.7%, and 19.1%, respectively. Three patients are currently surviving disease-free, with survival times of 130.4 months, 43.3 months, and 9.4 months, respectively. CONCLUSION: Although the current guidelines do not recommend surgical resection as the preferred treatment for postoperative abdominal metastases of HCC, surgical resection is recommended for patients with limited or solitary metastasis in the abdominal cavity.

Circulating lncRNA XLOC_009167 serves as a diagnostic biomarker to predict lung cancer.

BACKGROUND: Long noncoding RNAs (lncRNAs) have been proven to be involved in carcinogenesis and to be released into peripheral blood. Our objective was to develop a circulating lncRNA as a novel biomarker to predict lung cancer. METHODS: We analyzed the lncRNA expression profile in lung cancer patients by lncRNA array and identified lncRNA XLOC_009167 as a circulating biomarker using qRT-PCR in whole blood of lung cancer patients. The diagnostic value of was analyzed by area under curve (AUC) and the receiver operating characteristic (ROC) test. RESULTS: LncRNA XLOC_009167 was screened as a candidate biomarker for lung cancer and was up-regulated in both lung cancer tissues and cell lines. Notably, lncRNA XLOC_009167 in whole blood of lung cancer patients was highly expressed as compared with that in healthy controls or in patients with pneumonia. The values of AUC of lung cancer vs. healthy controls, and that of lung cancer vs. pneumonia were 0.7398 (95%CI = 0.6493 to 0.8303) and 0.7005 (95%CI = 0.5771 to 0.8240), respectively. Intriguingly, the ROC showed lncRNA XLOC_009167 was a better diagnostic potential compared to the traditional biomarkers (CYFR21-1, NSE and CA72-4), and the circulating lncRNA XLOC_009167 was found to be stable in whole blood under different conditions. CONCLUSIONS: LncRNA XLOC_009167 could serve as a novel diagnostic biomarker to distinguish lung cancer from benign lung disease and healthy controls.
