Impact of guideline adherence on the prognosis of Barcelona clinic liver cancer stage B hepatocellular carcinoma

BACKGROUND Patients with Barcelona clinic liver cancer(BCLC)stage B hepatocellular carcinoma(HCC)are considerably heterogeneous in terms of tumor burden,liver function,and performance status.To improve the poor survival outcomes of these patients,treatment approaches other than transarterial chemoembolization(TACE),which is recommended by HCC guidelines,have been adopted in realworld clinical practice.We hypothesize that this non-adherence to treatment guidelines,particularly with respect to the use of liver resection,improves survival in patients with stage B HCC.AIM To assess guideline adherence in South Korean patients with stage B HCC and study its impact on survival.METHODS A retrospective analysis was conducted using data from 2008 to 2016 obtained from the Korea Central Cancer Registry.Patients with stage B HCC were categorized into three treatment groups,guideline-adherent,upward,and downward,based on HCC guidelines recommended by the Asian Pacific Association for the Study of the Liver(APASL),the European Association for the Study of the Liver(EASL),and the American Association for the Study of Liver Diseases(AASLD).The primary outcome was HCC-related deaths;tumor recurrence served as the secondary outcome.Survival among the groups was compared using the Kaplan-Meier method and the log-rank test.Predictors of survival outcomes were identified using multivariable Cox regression analysis.RESULTS In South Korea, over the study period from 2008 to 2016, a notable trend was observed in adherence to HCCguidelines. Adherence to the EASL guidelines started relatively high, ranging from 77% to 80% between 2008 and2012, but it gradually declined to 58.8% to 71.6% from 2013 to 2016. Adherence to the AASLD guidelines began at71.7% to 75.9% from 2008 to 2010, and then it fluctuated between 49.2% and 73.8% from 2011 to 2016. In contrast,adherence to the APASL guidelines remained consistently high, staying within the range of 90.14% to 94.5%throughout the entire study period. Upward treatment, for example with liver resection, liver transplantation, orradiofrequency ablation, significantly improved the survival of patients with BCLC stage B HCC compared to thatof patients treated in adherence to the guidelines (for patients analyzed according to the 2000 EASL guidelines, the5-year survival rates were 63.4% vs 27.2%, P < 0.001), although results varied depending on the guidelines.Progression-free survival rates were also significantly improved upon the use of upward treatments in certaingroups. Patients receiving upward treatments were typically < 70 years old, had platelet counts > 105/μL, andserum albumin levels ≥ 3.5 g/dL.CONCLUSIONAdherence to guidelines significantly influences survival in South Korean stage B HCC patients. Curativetreatments outperform TACE, but liver resection should be selected with caution due to disease heterogeneity.

Histologic Classification of Thymoma and Its Relationship with Myasthenia Gravis and Clinical Stages of the Tumor

Objective： To investigate the relationship among the latest WHO classification of thymoma, myasthenia gravis （MG） and clinical stages. Methods： To review the pathological sections of 74 patients with thymoma from 1980-2004 using WHO classification （1999）, the statistical software was used to analyze the relationship among the WHO classification, MG and clinical stages. Results： （1） Two cases of type A, 23 cases of type AB, 4 cases of type B1, 27 cases of type B2, 16 cases of type B3 and 2 cases of type C were classified. Type B2 more likely accompanied MG （P〈0.05）, while none with MG occurred for type C. （2） One patient was in stage Ⅰ, 30 were in stage Ⅱ, 38 were in stage Ⅲ, and 5 were in stage Ⅳ. The latest histologic classification was significantly correlated with Masaoka stages （P〈0.01）. Conclusion： The latest WHO classification was correlated with occurrence of MG and finely reflected clinical stage. It can also evaluate the prognosis of patients.

Peripheral T-lymphocyte subpopulations in different clinical stages of chronic HBV infection correlate with HBV load

AIM： To characterize the peripheral T-cell subpopulation profiles and their correlation with hepatitis B virus （HBV） replication in different dinical stages of chronic HBV infection. METHODS： A total of 422 patients with chronic HBV infection were enrolled in this study. The patients were divided into three stages： immune-tolerant stage, immune active stage, and immune-inactive carrier stage. Composition of peripheral T-cell subpopulations was determined by flow cytometry. HBV markers were detected by enzyme-linked immunosorbent assay. Serum HBV DNA load was assessed by quantitative real-time poiymerase chain reaction.RESULTS： CD8^＋ T-cells were significantly higher in patients at the immune-tolerant stage than in patients at the immune-active and -inactive carrier stages （36.87 ± 7.58 vs 34.37 ± 9.07, 36.87 ± 7.58 vs 28.09 ± 5.64, P 〈 0.001）. The peripheral blood in patients at the immune-tolerant and immune active stages contained more CD8^＋ T-cells than CD4^＋ T-cells （36.87 ± 7.58 vs 30.23 ± 6.35, 34.37 ± 9.07 vs 30.92 ± 7.40, P 〈 0.01）, whereas the peripheral blood in patients at the immune- inactive carrier stage and in normal controls contained less CD8^＋ T-cells than CD4^＋ T-cells （28.09 ± 5.64 vs 36.85 ±6.06, 24.02 ± 4.35 vs 38.94 ± 3.39, P 〈 0.01）. ANOVA linear trend test showed that CD8^＋ T-cells were significantly increased in patients with a high viral load （39.41 ± 7.36, 33.83 ± 7.50, 31.81 ± 5.95 and 26.89 ± 5.71, P 〈 0.001）, while CD4^＋ T-cells were significantly increased in patients with a low HBV DNA load （37.45 ± 6.24, 33.33 ± 5.61, 31.58 ± 6.99 and 27.56 ± 5.49, P 〈 0.001）. Nultiple regression analysis displayed that log copies of HBV DNA still maintained its highly significant coefficients for T-cell subpopulations, and was the strongest predictors for variations in CD3^＋, CD4^＋ and CD8^＋ cells and CD4^＋/CD8^＋ ratio after adjustment for age at HBV-infection, maternal HBV-infection status, presence of hepatitis B e antigen and HBV mutation.CONCLUSION： Differences in peripheral T-cell subpopulation profiles can be found in different clinical stages of chronic HBV infection. T-cell impairment is significantly associated with HBV load.

Assessment of quality of life for the patients with cervical cancer at different clinical stages

With improved overall survival of cervical cancer patients, the importance of the quality of life (QOL) is increasingly recognized. This study was conducted to compare the QOL of women with different stage cervical cancer before and after treatment to facilitate improved cervical cancer prevention and treatment. We used the generic Medical Outcomes Study Short Form-36 (MOS SF-36) to collect QOL information. Based on SF-36, we interviewed cervical cancer patients at West China Second Affiliated Hospital and Sichuan Cancer Hospital between May 2010 and January 2011. A total of 92 patients with precancerous lesions, 93 with early cancer, and 35 with advanced cancer responded to our survey. Average physical component summary (PCS) scores were significantly different between the three groups at every time point (P < 0.05). Average mental component summary (MCS) scores were significantly different between the three groups after treatment (P < 0.05). Average PCS and MCS scores increased gradually from the pretreatment to posttreatment period for patients with precancerous lesions. However, they reached the lowest at 1 month after treatment for patients with early and advanced cancers and rebounded between 1 and 6 months after treatment. Our results indicate that patients with precancerous lesions and early cervical cancer show better overall QOL than do those with advanced cervical cancer. Additionally, patients with early cancer recover more quickly than do those with advanced cancer in terms of both physical and mental functions. Thus, early detection and treatment initiatives may improve the QOL for patients with precancerous lesions and cervical cancer.

Clinical stages of recurrent hepatocellular carcinoma: A retrospective cohort study

BACKGROUND Hepatocellular carcinoma(HCC)is the second leading cause of cancer-related death worldwide,and has relatively high recurrence rates.Few studies have been published on the clinical stages of recurrent HCC.AIM To assess the applicability of the Barcelona Clinic Liver Cancer(BCLC)staging for recurrent HCC and the need to establish clinical stage criteria for recurrent HCC.METHODS The clinicopathological data of 81 patients with recurrent HCC who were admitted to the Hospital of Guangxi Zhuang Autonomous Region from January 2013 to December 2017 were collected.The patients were divided into three groups according to the BCLC staging system as follows:(1)Group A with BCLC stage A,51 patients;(2)Group B with BCLC stage B,14 patients;and(3)Group C with BCLC stage C,16 patients.The median time to tumor recurrence and the median overall survival were compared.RESULTS The median time to tumor recurrence in groups A,B,and C was 16±1.5 mo,10±2.8 mo,and 6±0.5 mo,respectively,with a statistically significant difference among them(χ^(2)=70.144,P<0.05);no statistically significant difference was noted between group A and group B(χ^(2)=2.659,P>0.05),although there were statistically significant differences between group A and group C and between group B and group C(χ^(2)=62.110,and 19.972,P<0.05).The median overall survival in groups A,B,and C were 42±5.1 mo,22±3.1 mo,and 13±1.8 mo,respectively,with a statistically significant difference among them(χ2=38.949,P<0.05);there were statistically significant differences between group A and group B,group A and group C,and group B and group C(χ2=9.577,37.172,and 7.183,respectively;P<0.05).CONCLUSION There are different prognoses in recurrent HCC patients according to the BCLC staging.Therefore,BCLC staging is applicable to recurrent HCC and it is essential to formulate clinical stage criteria for recurrent HCC.

Clinical outcomes in patients with stage non-seminomatous germ cell cancer

This study assesses the long-term outcomes in Han Chinese patients with clinical stage I non-seminomatous germ cell testicular cancer （CSI NSGCT） treated with surveillance, retroperitoneal lymph node dissection （RPLND） and adjuvant chemotherapy. We retrospectively evaluated 89 patients with a mean age of 26.5 years. After orchiectomy, 37 patients were treated with surveillance, 34 underwent RPLND and 18 were managed with chemotherapy. The overall survival rate, the recurrence-free survival rate and the risk factors were evaluated. The median follow-up length was 92 months （range： 6-149 months）. Thirteen of the 89 patients （14.6%） had relapses, and one died by the evaluation date. The overall survival rate was 98.9%. The cumulative 4-year recurrence-free rates were 80.2%, 92.0% and 100% for the surveillance, RPLND and chemotherapy groups, respectively. The disease-free period tended to be briefer in patients with a history of cryptorchidism and those with stage Is. Therefore, surveillance, RPLND and adjuvant chemotherapy might be reliable strategies in compliant patients with CSI NSGCT. Surveillance should be recommended for patients with the lowest recurrence rate, especially those without lymphovascular invasion. This study might aid the establishment of a standard therapy for CSI NSGCT in China.

Reverse time-dependent effect of alphafetoprotein and disease control on survival of patients with Barcelona Clinic Liver Cancer stage C hepatocellular carcinoma

AIM To characterize the survival of cirrhotic patients with Barcelona Clinic Liver Cancer(BCLC) stage C hepatocellular carcinoma(HCC) and to ascertain the factors predicting the achievement of disease control(DC).METHODS The cirrhotic patients with BCLC stage C HCC evaluated by the Hepatocatt multidisciplinary group were subjected to the investigation. Demographic, clinical and tumor features, along with the best tumor response and overall survival were recorded. RESULTS One hundred and ten BCLC stage C patients were included in the analysis; the median overall survival was 13.4 mo(95%CI: 10.6-17.0). Only alphafetoprotein(AFP) serum level > 200 ng/m L and DC could independently predict survival but in a time dependent manner, the former was significantly associated with increased risk of mortality within the first 6 mo of follow-up(HR = 5.073, 95%CI: 2.159-11.916, P = 0.0002), whereas the latter showed a protective effect against death after one year(HR = 0.110, 95%CI: 0.038-0.314, P < 0.0001). Only patients showing microvascular invasion and/or extrahepatic spread recorded lower chances of achieving DC(OR = 0.263, 95%CI: 0.111-0.622, P = 0.002).CONCLUSION The BCLC stage C HCC includes a wide heterogeneous group of cirrhotic patients suitable for potentially curative treatments. The reverse and time dependent effect of AFP serum level and DC on patients' survival confers them as useful predictive tools for treatment management and clinical decisions.
