ABSTRACT
Objective@#To investigate the correlation between Ishak inflammation score and the clinicopathological characteristics and recurrence of patients with hepatocellular carcinoma (HCC) after curative resection, and then set up a recurrence nomogram for HCC.@*Methods@#A total of 326 patients with HCC after curative resection from January 2006 to December 2009 were studied retrospectively as training cohort and 110 HCC patients after surgery from January 2010 to December 2012 were used as validation cohort.Clinical follow-up data and peritumoral Ishak inflammation score in training cohort were used to set up a nomogram predicting recurrence of HCC, which was verified by validation cohort. Kaplan-Meier and Cox proportional hazard regression model were used to analyzed accuracy of model prediction.@*Results@#According to Ishak inflammation score, patients were divided into four subgroups: Grade Ⅰ(1-4 scores), Grade Ⅱ(5-8 scores), Grade Ⅲ (9-12 scores) and Grade Ⅳ(13-18 scores). Ishak inflammation score were associated with aspartate transaminase(median 36.0 U/L, P=0.011), γ-glutamyl transpeptidase(median 54.5 U/L, P=0.005), HBV-DNA load(20.5%>106 copies/ml, P=0.015) and microvascular invasion(26.7% positive, P=0.021). Multivariate analysis showed that Ishak inflammation score(P=0.007), HBV-DNA load(P<0.01), tumor size(P=0.001) and microvascular invasion(P=0.001) were related with the recurrence of HCC patients.These four risk factors were incorporated into the nomogram.Calibration curves of the nomogram had good agreement between prediction and observation in the probability of recurrence.Both C-indexes and receiver operating characteristic curve analyses revealed that this nomogram had better predictive abilities than those of the AJCC and Barcelona Clinic Liver Cancer (BCLC) stage systems.These results were verified by the validation cohort.@*Conclusion@#A nomogram based on Ishak inflammation score could accurately predict the recurrence of HCC and contribute to HCC relapse surveillance after curative hepatectomy.
ABSTRACT
Objective: To investigate the correlation between FIB-4 and the clinicopathological characteristics and prognosis of patients with hepatocellular carcinoma (HCC) after curative resection. Methods: From January 2009 to December 2012, the clinicopathological and follow-up data of 245 patients with HCC after curative resection were retrospectively studied. Their survival was calculated using the Kaplan-Meier method. The Cox proportional hazard regression model was used for the multivariate analysis. Results: According to FIB-4 index, patients were divided into two subgroups: FIB-4Ⅰ(≤3.25) and FIB-4Ⅱ(>3.25). FIB-4 could predict liver cirrhosis severity (Ishak grade, Grade 1-5 vs. Grad 6, r=0.681, P<0.001). It was associated with liver function such as:aspartate transaminase (P<0.001)、total bilirubin (P=0.009)、albumin (P=0.001) and platelet count (P<0.001) other than tumor clinicopathologic features. Both univariate and multivariate analysis showed FIB-4 could predict the prognosis of HCC patients (Overall survival: P=0.037 and 0.011; Recurrencefree survival: P=0.027 and P=0.043, respectively). Conclusion: The preoperative FIB-4 index could be used as a prognostic marker for the prognosis of HCC after curative hepatectomy.
ABSTRACT
This case-control study aimed to clarify the short- and long-term outcomes of laparoscopic surgery for rectal cancer after neoadjuvant chemo radiotherapy compared with conventional open resection. Between January 2008 and December 2014, a series of 227 patients with rectal cancer underwent radical surgery after neoadjuvant chemo radiotherapy. Age, gender, American Society of Anesthesiologists score, clinical stage, and type of resection were matched by propensity scoring and 106 patients [53 patients with laparoscopic total mesorectal excision and 53 patients with open resection] were selected for analysis. There were no significant differences in the clinicopathological features between the two groups. With regard to short-term outcomes, blood loss, postoperative analgesia and hospital stay were significantly shorter in the laparoscopy group than in the open group, whereas operative time was significantly longer in the laparoscopy group than in the open group. The overall morbidity was similar in the two groups. There were no significant differences in the 5-year overall and disease-free survival rates between the two groups. In summary, laparoscopic surgery may be both feasible and efficient compared with open resection for rectal cancer after neoadjuvant chemo radiotherapy
