Prediction of Early Recurrence After R0 Resection for Gallbladder Carcinoma of Stage T1b-T3.

PURPOSE: The time-to-tumor recurrence can predict the prognosis of hepatobiliary cancers following curative-intent resection. Therefore, for patients with gallbladder carcinoma (GBC) of stage T1b-T3 who had undergone R0 resection, we investigated the risk factors for early recurrence of GBC and their prognosis. PATIENTS AND METHODS: A total of 260 patients with GBC with T1b-T3 disease and an R0 margin were identified. Their clinicopathologic characteristics, perioperative details and prognostic data were reviewed. Survival analyses were carried out using the Kaplan-Meier method. Logistic regression models were used to identify the risk factors for early recurrence. RESULTS: The optimal cutoff for early recurrence was 29 months. Early recurrence tended to result in relapse far from the primary tumor, and such patients tended to have significantly worse overall survival. Multivariate analysis revealed that T3 disease, N1/N2 stage, poor differentiation of tumor, and lymphovascular invasion (LI) were associated with a greater risk of early recurrence. Patients diagnosed as having GBC incidentally and who had the risk factors of early recurrence were more likely to benefit from re-resection 2-4 weeks after a cholecystectomy. CONCLUSION: T3 stage, N1-N2 stage, poor differentiation, and LI were independent risk factors associated with early recurrence for patients with GBC with stage T1b-T3 disease after R0 resection.

Laparoscopic appendectomy is safe and feasible in pregnant women during second trimester: A retrospective study in a top-level Chinese center.

Acute appendicitis (AA) is the most common nonobstetric surgical emergency during pregnancy. According to the current guidelines and meta-analyses, traditional open appendectomy (OA) is still recommended for pregnant patients over laparoscopic appendectomy (LA), which might be associated with higher rates of fetal loss. Previous studies and experiences indicated that LA might be safe in the second trimester of pregnancy. The current study aimed to evaluate the safety and feasibility of LA in pregnant women during the second trimester.At our institution, a retrospective study was conducted with pregnant patients who underwent LA or OA during the second trimester between January 2016 and August 2018.A total of 48 patients were enrolled. Of them, 12 were managed with laparoscopy and 36 with the open approach. We found that the LA group had higher BMIs than the OA group (4.0 ±â€Š4.3 vs 21.5 ±â€Š2.9, P = .031). The financial results showed that the average daily medical costs for patients who underwent LA was higher than those who underwent OA (444 ±â€Š107 US$ vs 340 ±â€Š115 US$, P = .009), while the total cost of hospitalization was comparable between the 2 approaches. The perioperative and obstetric outcomes were comparable between LA and OA. In each group, only 1 patient had fetal loss. No "Yinao" was found in any of the patients in the LA group.In this study, with the proven advantages of the laparoscopic techniques, LA was found to be safe and feasible for pregnant women during the second trimester.

Elevated platelet distribution width predicts poor prognosis in hilar cholangiocarcinoma.

Although the platelet distribution width (PDW) has been reported as a reliable predictor of prognosis in several types of cancer, to our knowledge the prognostic value of PDW in hilar cholangiocarcinoma (HC) has not been studied. The aim of the study was to investigate the prognostic value of PDW in HC patients. A retrospective analysis of 292 consecutively recruited HC patients undergoing radical resection with at least a 5-year follow-up. The optimal cutoff value of PDW was determined by receiver operating characteristic (ROC) curve. Survival analysis by the Kaplan-Meier method and the difference between the clinico-pathologic variables and survival was evaluated by log-rank analysis. Multivariate analysis identified independent prognostic risk factors of overall survival (OS). ROC curve analysis suggested that the optimal cutoff value for the PDW was 16.55. There were significant associations of high PDW with high white blood cell (P < .001) and high neutril-to-lymph ratio (P < .001). In a multivariate analysis, the PDW was an independent prognostic factor for overall survival (HR = 2.521, 95% CI 1.832-3.470, P < .001). In conclusions, our findings indicate that PDW may have clinical significance in predicting OS after surgery in HC patients.

A simple scoring system to predict early recurrence of Bismuth-Corlette type IV perihilar cholangiocarcinoma.

BACKGROUND: Early recurrence has been reported to be predictive of a poor prognosis for patients with perihilar cholangiocarcinoma (pCCA) after resection. The objective of our study was to construct a useful scoring system to predict early recurrence for Bismuth-Corlette type IV pCCA patients in clinic and to investigate the value of early recurrence in directing post-operative surveillance and adjuvant therapy. METHODS: In total, 244 patients who underwent radical resection for type IV pCCA were included. Data on clinicopathological characteristics, perioperative details and survival outcomes were analyzed. Survival curves were generated using the Kaplan-Meier method. Univariate and multivariate logistic-regression models were used to identify factors associated with early recurrence. RESULTS: Twenty-one months was defined as the cutoff point to distinguish between early and late recurrence. Univariate and multivariate analysis revealed that CA19-9 level >200 U/mL, R1 resection margin, higher N category and positive lymphovascular invasion were independent predictors of early recurrence. The scoring system was constructed accordingly. The early-recurrence rates of patients with scores of 0, 1, 2, 3, 4, and 5 were 23.9%, 38.7%, 60.0%, 78.6%, 83.4%, and 100%, respectively. Adjuvant therapy was significantly associated with higher overall survival rate for patients with early recurrence, but not for those with late recurrence. Patients in the early-recurrence group with scores ≥2 had better prognoses after adjuvant therapy. CONCLUSIONS: A simple scoring system using CA19-9 level, N category, resection margin and lymphovascular invasion status could predict early recurrence, and thus might direct post-operative surveillance and adjuvant therapy for patients with type IV pCCA.
