Should we change the treatment plan in early hepatocellular carcinoma with chronic kidney disease?

BACKGROUND: Chronic kidney disease (CKD) has been considered to be a poor prognostic factor for hepatocellular carcinoma (HCC). However, few studies have focused on early HCC and the impact of CKD on survival, which should be considered in curative treatment for early HCC. MATERIALS AND METHODS: Patients with BCLC stage 0/A were enrolled from 2009 to 2019. A total of 383 patients were divided into Control group and CKD group, based on estimated glomerular filtration rate. Overall survival (OS) and disease-free survival (DFS) of different treatments were determined using the Kaplan-Meier method. RESULTS: The Control group had a significantly better OS than the CKD group (72.6 months vs. 56.7 months; p = 0.003). DFS was similar between the groups (62.2 months vs. 63.8 months, p = 0.717). In the Control group, the surgically treated (OP) group had significantly superior OS (65.0 months vs. 80.0 months, p = 0.014) and DFS (50.9 months vs. 70.2 months, p = 0.020) than the radiofrequency ablation-treated group. In the CKD group, the OP group showed a survival advantage in OS (70.6 months vs. 49.2 months, p = 0.004), while DFS was similar between treatment groups (56.0 months vs. 62.2 months, p = 0.097). CONCLUSION: CKD should not be considered to be a poor prognostic factor in early HCC patients. Moreover, hepatectomy should be carried out in CKD patient with early HCC for better prognosis if feasible.

A Novel Predictive Scoring System for 90-Day Mortality among Patients with Hepatocellular Cell Carcinoma Receiving Major Hepatectomy.

PURPOSE: Hepatocellular carcinoma (HCC) is a major malignancy and the common cause of cancer-related deaths. Surgical intervention provides superior long-term survival outcomes; however, perioperative mortality is a major concern for clinicians while making treatment decisions, especially for major hepatectomy. Scoring systems for predicting 90-day mortality in patients with HCC undergoing major hepatectomy are not available. METHODS: This study used the Taiwan Cancer Registry Database that is linked to the National Health Insurance Research Database to analyze data of 60,250 patients with HCC who underwent major hepatectomy and determine risk factors to establish a novel predictive scoring system. By using the stepwise selection of the multivariate Cox proportional hazards model, we divided the patients with HCC undergoing major hepatectomy into four risk groups. RESULTS: The Chang Gung-PohAi predictive scoring system exhibited significant differences in the 90-day mortality rate among the four risk groups (very low risk: 2.42%, low risk: 4.09%, intermittent risk: 17.1%, and high risk: 43.6%). CONCLUSION: The Chang Gung-PohAi predictive scoring system is a promising tool for predicting 90-day perioperative mortality in patients with HCC undergoing major hepatectomy.

Sac transection versus sac reduction during laparoscopic herniorrhaphy: A systematic review and meta-analysis.

Hernia repair techniques have evolved recently; however sac handling remains a critical step. Transection of the herniated sac as opposed to total sac reduction may simplify the procedure. However, residual sac tissue may increase the risk for seroma formation. We performed a systemic review and meta-analysis to evaluate the safety and feasibility of transecting the hernia sac during laparoscopic herniorrhaphy. Relevant literature search was performed in PubMed, EMBASE, SCORPUS, and the Cochrane Library databases. Relevant studies that compared total reduction with transection of the herniated sac during laparoscopic herniorrhaphy were included. The primary outcome measure was the incidence of seromas. We also analyzed secondary outcomes including operative duration, postoperative pain scores, complications, and hernia recurrence rate. Of the 330 studies identified, four studies published between 2002 and 2020, with sample sizes ranging from 70 to 520 patients, met the inclusion criteria. Overall, 848 hernias were evaluated. We observed a high incidence of seroma formation in the sac transection group compared to that in the sac reduction group (OR 2.41; 95% CI 1.39 to 4.17, P = 0.002), but the groups did not differ significantly with respect to factor such as operative duration, postoperative complications, and pain score. Herniated sac transection during laparoscopic herniorrhaphy might be associated with a higher risk of seroma formation than that observed with sac reduction. The former approach did not show any significant benefits compared to the latter approach with respect to operative duration and postoperative complications.

Livestock-associated methicillin-resistant Staphylococcus aureus ST9 in pigs and related personnel in Taiwan.

BACKGROUND: A livestock-associated (LA) methicillin-resistant Staphylococcus aureus (MRSA) strain sequence type 398 (ST398) is found related to animals and humans in Europe and North America. To evaluate the nasal carriage of MRSA among pigs and related workers in Taiwan, we conducted this study. METHODS: From June 25 to October 1 2012, a total of 641 and 100 nasal swabs were obtained from pigs and related workers, respectively, from 22 pig farms nationwide and 2 pig auction markets in Taiwan. All MRSA isolates were molecularly characterized. RESULTS: Overall, the nasal carriage rate of MRSA was 14.4% for pigs and 13% for humans. The carriage rate for pigs younger than 3 months was significantly higher than those older than 3 months (25.4% vs. 5.8%, p<.001). Percentage of MRSA-positive pig farms was 59.1% (13/22). The carriage rate for pigs in large-scale herds (≥ 10000 pigs) was significantly higher than that in small-scale (34.3% vs. 7.0%, p<.001) and that in auction markets (3.8%). The carriage rate was 19.2% (10/52) for pig farm workers, and the rate in large-scale farms was significantly higher than that in small-scale (36.8% vs. 9.1%, p = .014). Except for 3 isolates from humans, the other 99 isolates belonged to sequence type (ST) 9. 83 of 89 isolates from pigs shared a common pulsotype, which was also shared by 6 isolates from humans. CONCLUSION: More than 10% of pigs and related workers in Taiwan carried LA-MRSA ST9 in nares and cross-species transmission of LA-MRSA was documented by molecular methods.
