    • Clinicopathological and radiologic features of postoperative recurrence of lung adenocarcinoma with micropapillary/solid structure

      ObjectiveTo investigate the radiological and clinicopathological factors affecting the postoperative recurrence of early lung adenocarcinoma with micropapillary/solid structure.MethodsA total of 198 patients undergoing surgical resection for early stage lung adenocarcinoma in the First Affiliated Hospital of Nanjing Medical University from January 2016 to August 2019 were enrolled, including 100 males and 98 females, aged 28-82 (53.5±9.5) years. All patients were allocated to a recurrence group (n=21) and a non-recurrence group (n=177) according to postoperative recurrence status. Correlations of imaging and clinical features and clinical outcomes were analyzed to determine prognostic significance.ResultsThe mean follow-up time was 27.0±11.2 months. There was no statistical difference in the imaging features of tumor maximum diameter in mediastinal window (P=0.014), C/T ratio (P=0.001), bronchial positive sign (P=0.015), pathological features of vascular invasion (P=0.024) and postoperative chemotherapy (P<0.001) between the two groups. In multivariate analysis, vascular invasion was the only independent prognostic factor (OR=0.146, P=0.047).ConclusionVascular invasion is an independent risk factor for postoperative recurrence of early-stage lung adenocarcinoma with micropapillary/solid structure.

    • Prophylactic Effect of Lamivudine Monotherapy Against Hepatitis B Recurrence Following Liver Transplantation

      【Abstract】ObjectiveTo investigate the prophylactic effect of lamivudine monotherapy on the recurrence of hepatitis B after liver transplantation. MethodsThirtyone patients with hepatitis B related benign decompensated cirrhosis who underwent liver transplantation between February 1999 to June 2002 and survived more than 3 months were analyzed retrospectively. Lamivudine was administered to each patient after operation and some patients before operation for the prophylaxis of HBV recurrence. The HBV markers and HBV DNA in serum and bioptic liver tissues in all patients were evaluated before and after operation. ResultsTotal HBV recurrence rate was 19.4%(6/31) during average 38.2 months (3.2-70.2 months) follow up. HBV recurrence rate was 7.1%(2/28), 16.0%(4/25), 26.1%(6/23) and survival rate was 87.1%(27/31), 80.6%(25/31), 66.1%(20.5/31) after 1-, 3-and 5-year, respectively. One hundred milligram lamivudine administration peroral daily for 2 weeks prior to transplantation enable HBeAg 54.5%(6/11) and HBV DNA 50.0%(5/10) positive patients convert to negative respectively. ConclusionPreoperative administration of lamivudine monotherapy can effectively prevent allograft from HBV re-infection after liver transplantation. Lamivudine should be used to convert HBV DNA and HBeAg to negative.

    • Analysis of clinical features, treatment methods, and prognostic influence factors in patients with malignant peripheral nerve sheath tumor

      Objective To investigate the clinical features, treatment methods, and prognostic influence factors of patients with malignant peripheral nerve sheath tumor (MPNST). MethodsA retrospective analysis was conducted on 96 MPNST patients treated between January 1, 2015 and December 31, 2021. There were 46 males and 50 females, aged between 15 and 87 years (mean, 48.2 years). The tumors were located in the trunk in 50 cases, extremities in 39 cases, and head and neck in 7 cases. The maximum tumor diameter was <5 cm in 49 cases, ≥5 cm in 32 cases, with 15 cases missing data. Tumor depth was deep in 77 cases and superficial in 19 cases. The Fédération Nationale des Centres de Lutte Contre le Cancer (FNCLCC) histological grading was G1 in 9 cases, G2 in 12 cases, and G3 in 34 cases, with 41 cases missing data. There were 37 recurrent MPNST cases, 32 cases with neurofibromatosis type 1 (NF1), and 26 cases in stage Ⅳ. Postoperative adjuvant radiotherapy was administered to 25 patients, perioperative chemotherapy to 45 patients, and anlotinib-targeted therapy to 30 patients. R0 resection was achieved in 73 cases. Patients were divided into groups based on the presence or absence of NF1, and baseline data between the two groups were compared. Kaplan-Meier curves were generated to assess disease-free survival (DFS) and overall survival (OS) based on various factors (age, gender, presence of NF1, recurrent MPNST, stage Ⅳ MPNST, FNCLCC grade, R0 resection, tumor location, tumor size, tumor depth, perioperative chemotherapy, postoperative adjuvant radiotherapy, and anlotinib-targeted therapy), and differences between survival curves were analyzed using the Log-Rank test. Multivariate COX proportional hazards regression was used to identify independent prognostic factors for MPNST. Results Patients with NF1 had a significantly higher proportion of superficial tumors and lower FNCLCC grade compared to those without NF1 (P<0.05); no significant difference was found for other variables (P<0.05). Kaplan-Meier analysis showed that recurrent MPNST, stage Ⅳ MPNST, FNCLCC grade, R0 resection, perioperative chemotherapy, and anlotinib-targeted therapy were factors influencing 1-year DFS (P<0.05), while stage Ⅳ MPNST, FNCLCC grade, and perioperative chemotherapy were factors affecting 3-year OS (P<0.05). Multivariate COX proportional hazards regression analysis revealed that recurrent MPNST and high-grade FNCLCC (G3) were independent prognostic factors for 1-year DFS (P<0.05), while stage Ⅳ MPNST, superficial tumor depth, age over 60 years, postoperative adjuvant radiotherapy, and anlotinib-targeted therapy were independent prognostic factors for 3-year OS (P<0.05). Conclusion MPNST patients with NF1 tend to have more superficial tumors and lower FNCLCC grades. FNCLCC grade, R0 resection, and adjuvant therapies, including radiotherapy and anlotinib-targeted therapy, are closely associated with MPNST prognosis. Complete surgical resection should be prioritized in clinical management, along with adjuvant treatments such as radiotherapy and targeted therapy of anlotinib to improve patient outcomes.

    • The expression change of stemness-related markers in recurrent hepatocellular carcinoma and relationship with clinicopathologic characteristics

      ObjectiveTo investigate the expression change characteristic of stemness-related markers for recurrent hepatocellular carcinoma (HCC), and to discuss the relationship between stemness-related markers and clinicopathologic characteristics of HCC.MethodsWe collected 25 recurrent HCC patients who also had the first liver resection for HCC in Sichuan Cancer Hospital from Jan. 2010 to Oct. 2018. Immunohistochemistry was used to compare expressions of CD133, CD90, CD117, and epithelial cell adhesion molecule (EpCAM) in HCC tissues. Fluorescence in situ hybridization was used to detect telomere length.ResultsThe primary HCC had higher platelet count, larger tumor, less microvascular invasion (MVI), and less multiple HCC than the recurrent HCC (P<0.05), but the expressions of CD90, CD133, CD117, and EpCAM were not significantly differed after recurrence (P>0.05). The expressions of CD90, CD133, CD117, and EpCAM were not associated with tumor size, tumor number, Barcelona Clinic Liver Cancer Staging (BCLC staging), satellite nodules, and differentiation (P>0.05). The MVI-positive group had a significantly higher expression level of EpCAM (P=0.016) and longer telomere length (P=0.001). The telomere length was longer for tumors diameter less than 5 cm (P=0.038) and poor differentiation (P=0.046). Correlation analysis found that there was no relationship between telomere length and expression levels of EpCAM (r=–0.092, P=0.513), CD90 (r=–0.235, P=0.100), CD133 (r=0.024, P=0.867), and CD117 (r=–0.277, P=0.052), but an apparent positive correlation between expression levels of EpCAM and CD133 was found (r=0.358, P=0.011). Survival analysis found that poor differentiation (P=0.003) and BCLC B–C staging (P=0.040) were the risk factors of disease-free survival for patients after first HCC resection, and BCLC B–C staging (P=0.017) and tumor diameter more than 5 cm (P=0.035) were the risk factors for recurrent HCC.ConclusionsRecurrent HCC had similar stemness-related markers expression and longer telomere length. Expression level of EpCAM and telomere length were associated with MVI.

      Objective To observe efficacy of rapamycin combined with sorafenib in hepatocellular carcinoma (HCC) patients with tumor recurrence after liver transplantation beyond Milan criteria. Methods Forty-one beyond Milan criteria HCC patients who underwent the classic orthotopic liver transplantation without bypass and the tumor postoperatively recurred in the Tianjin First Center Hospital from February 1, 2012 to August 31, 2015 were collected retrospectively, then were divided into a local treatment group (n=21) and a comprehensive treatment group (n=20). The local treatment included the surgical resection, radiofrequency ablation, transcatheter arterial chemoembolization, radioactive seed implantation, etc.. The comprehensive treatment was on the basis of the local treatment plus rapamycin in combination with sorafenib. Results There were 12 patients with stable disease and 9 patients with progressive disease in the local treatment group. There were 12 patients with partial response, 10 patients with stable disease and 8 patients with progressive disease in the comprehensive group. In the local treatment group and the comprehensive treatment group, the median survival time were 9 months and 12 months, and the 1-year and 2-year survival rates after the recurrence were 14% versus 55%, 0 versus 15%, respectively. The survival of the comprehensive treatment group was significantly better than that of the local treatment group (P<0.01). Conclusion Combination of rapamycin and sorafenib in HCC patients with tumor recurrence after liver transplantation beyond Milan criteria can significantly improve survival time of patient with recurrence.

    • Clinical characteristics and postoperative recurrence factors of 1 106 patients with cardiac myxoma

      Objective To summarize the clinical characteristics and surgical treatment experience of 1 106 patients with cardiac myxoma. Methods Clinical data of 1 106 patients with cardiac myxoma who underwent surgical treatment in Beijing Anzhen Hospital from 2002 to 2018 were retrospectively analyzed. There were 749 (67.7%) females and 357 (32.3%) males. Results The highest incidence rate was at the age of 51-70 years. The location of the disease was: left atrium in 987 (89.2%) patients, right atrium in 99 (9.0%) patients, left ventricle in 10 (0.9%) patients, right ventricle in 8 (0.7%) patients. There were 1 013 patients of heart classification (NYHA) Ⅰ-Ⅱ and 93 patients of Ⅲ-Ⅳ. There were 301 patients with cerebral infarction and 57 patients with peripheral arterial embolism. Tumor size was closely related to hemodynamic symptoms (P≤0.05), but not to peripheral vascular embolism (P>0.05). Two (0.2%) patients died in hospital and 306 patients were followed up, with a follow-up rate of 27.7%. The median follow-up time was 7 years (range, 1-18 years). One patient died of all causes, and 23 patients recurred, with a recurrence rate of 2.1%. Among 23 recurrent patients, 15 (65.2%) patients were atypical myxoma and 8 (34.8%) patients were typical myxoma. There was no statistical difference in aortic clamping time, ICU stay time, ventilator-assisted breathing time, postoperative hospital stay time, postoperative mortality, or cardiac ejection fraction at discharge between the reoperation in 23 recurrent patients and the first operation in 1 083 non-recurrentpatients. Conclusion Cardiac myxoma is more common in middle-aged and elderly women, and it often occurs in the left atrium. The size of cardiac myxoma can affect the hemodynamic changes. Surgical treatment is effective. Atypical myxoma is more common in recurrent patients, and the effect is still satisfactory through surgical treatment.

    • Impact of blood glucose level after open radical hepatectomy on early recurrence of hepatocellular carcinoma

      ObjectiveTo investigate the impact of elevated fasting blood glucose (FBG) level after open radical hepatectomy on the early recurrence of hepatocellular carcinoma (HCC).MethodsThe clinical data of 112 patients with HCC who underwent the open radical hepatecomy from January 2013 to December 2014 in the Affiliated Hospital of Qingdao University were retrospectively analyzed. After the radical resection of HCC, 86 patients with level of FBG 3.9–6.1 mmol/L and 26 patients with level of FBG≥6.1 mmol/L were design into a normal FBG group and an elevated FBG group, respectively. The recurrence rates of HCC were compared between the two groups at 1- and 2-year after the opreation.ResultsThere were no significant differences between the 2 groups in the gender, age, history of alcohol drinking, hepatitis B history, preoperative ALT, AST, AFP and Child-Pugh classification, scope of hepatectomy, intraoperative hemorrhage, hepatic blood flow occlusion, diameter of maximal tumor, histopathological differentiation, tumor number, cirrhosis, satellite lesion, postoperative adjuvant TACE treatment or not (P>0.05). The postoperative 1- and 2-year recurrence rates of HCC were 19.8% (17/86) and 33.7% (29/86) in the normal FBG group and 42.3% (11/26) and 61.5% (16/26) in the elevated FBG group, respectively, showing significant differences between the 2 groups (P<0.05). The results of multivariate analysis showed that the level of FBG≥6.1 mmol/L, low histopathological differentiation, and no postoperative TACE treatment were the independent risk factors affecting tumor-free survival rate after the open radical resection of HCC (P<0.05). ConclusionsElevated FBG level after open radical resection has a stimulative effect on early recurrence of HCC. As a result, monitoring and controlling of FBG level after operation is helpful in decreasing early recurrence rate of patients with HCC.
