Predictive prognostic markers for immunotherapy are crucial and desperately required for clinical precise medicine. This retrospective study aimed to assess the efficacy of anti-PD-1 (programmed cell death protein 1) treatment and find the therapeutic prognostic biomarkers in advanced biliary tract cancer (BTC). A total of 60 patients of advanced BTC who received at least one dose of anti-PD-1 therapy between June 2016 and October 2019 were recruited and followed up till April 2020. Systemic immuneinflammation index (SII) and neutrophils-to-lymphocytes ration (NLR) were obtained from the routine circulating hematologic analysis before treatment. Serum 45-Plex Panel cytokines were detected using multiplexed bead immunoassays. Logistic regression nomogram was used to construct the algorithm model for prognosis prediction.Of the 60 patients, the overall benefit rate (OBR) was 38.3%, the median progression free survival (PFS), and overall survival (OS) were 4.0 mo (95% confidence interval [CI]: 2.28-5.72) and 13.0 mo (95% CI: 8.05-17.95), respectively. High levels of SII (≥720), NLR (≥4.3) and cytokine IFN-inducible protein-10 (IP-10; ≥45 pg/ml) indicated worse OS. Those with high SII (≥720) and high IP-10 (≥45 pg/ml) also had shorter PFS. The nomogram algorithm combining above three independent factors (SII, IP-10, and macrophage inflammatory protein-1β) had better efficacy in predicting OBR. Our study offers a simple, affordable, and noninvasive method to help physicians predict therapeutic response in BTC patients receiving anti-PD-1 antibody treatment.
There is not yet a consensus regarding a difference in prognosis for patients with hepatocellular carcinoma (HCC) with and without bile duct invasion (BDI). The present study aimed to clarify the prognostic importance of BDI on the short and long-term outcome of patients with HCC who underwent surgical resection. The present study evaluated HCC with BDI, including peripheral microscopic biliary invasion and revealed that the prognosis of patients with BDI was poorer compared with those without BDI. It should be noted that peripheral BDI also had a negative impact on the prognosis of patients with HCC. The clinical prognosis assessment revealed that BDI should be considered when assigning a disease stage. BDI, either macroscopic or microscopic, indicated a poor prognosis in patients with HCC who underwent curative resection, however it was not a surgical contraindication. Macroscopic BDI and hyperbilirubinemia were significantly associated with a dismal prognosis, which should alert surgeons.
Aim: To determine the efficacy and toxicities of sorafenib in the treatment of patients with multiple recurrences of hepatocellular carcinoma (HCC) after liver transplantation in a Chinese population. Methods: Twenty patients with multiple recurrences of HCC after liver transplantation were retrospectively studied. They received either transarterial chemoembolization (TACE) or TACE combined with sorafenib. Results: The median survival times (MST) after multiple recurrences was 14 months (TACE+sorafenib group) and 6 months (TACE only group). The difference was significant in MST between the two groups (P=0.005). The TACE + sorafenib group had more stable disease (SD) patients than the TACE group. The most frequent adverse events of sorafenib were hand-foot skin reaction and diarrhea. In the univariate analysis, preoperative bilirubin and CHILD grade are found to be significantly associated with tumor-free survival time, the survival time after multiple recurrences and overall survival time. TACE+sorafenib group showed a better outcome than single TACE treatment group. In the multivariate COX regression modeling, the preoperative high CHILD grade was found to be a risk factor of tumor-free survival time. In addition, the preoperative high bilirubin grade was also found to be a risk factor of survival time after recurrence and overall survival time. Furthermore, survival time after recurrence and overall survival time were also associated with therapeutic schedule, which was indicated by the GROUP. Conclusion: Treatment with TACE and sorafenib is worthy of further study and may have more extensive application prospects.
Background: This cohort study, based on a large sample of extensive hepatectomy cases, aimed to analyze the distribution of hepatectomy-related complications and to develop a predictive model of posthepatectomy liver failure (PHLF).Methods: Data of patients who underwent hepatectomy of ≥3 liver segments at the Eastern Hepatobiliary Surgery Hospital from 2000 to 2016 were collected and analyzed. Information on hepatectomy-related complications was collected and risk factors were analyzed. A total of 1,441 eligible patients were randomly assigned at 3:1 ratio into the derivation (n=1,080) and validation (n=361) cohorts. The multivariable logistic regression model was used to establish the prediction model of PHLF in the derivation cohort.Results: The incidence rates of PHLF, ascites, bile leakage, intra-abdominal bleeding, and abscesses were 58.22%, 10.76%, 11.17%, 9.71%, and 4.16%, respectively. The 90-day perioperative mortality rate was 1.32%. Multivariate analyses found that age, gender, platelet, creatinine, gamma-glutamyltransferase, thrombin time, fibrinogen, hepatitis B e (HBe) antigen positive, and number of resected liver segments were independent prognostic factors of PHLF in the derivation cohort and included in the nomogram. The prediction model demonstrated good discrimination [area under the curve =0.726, 95% confidence interval (CI), 0.696-0.760, P<0.0001] and calibration.Conclusions: Our study showed a high perioperative safety and a low risk of serious complications in patients who underwent major liver resection (MLR) at a large hepatobiliary surgery center. Routine preoperative clinical information can be used to develop a postoperative liver failure risk prediction model for rational planning of surgery.
