This study aimed to compare the efficacy and safety of drug-eluting bead transarterial chemoembolization (DEB-TACE) vs conventional TACE (cTACE) in hepatocellular carcinoma (HCC) patients with multiple cTACE treatments history. Eighty-one HCC patients with multiple cTACE treatments history who underwent DEB-TACE (N = 42) and cTACE treatment (N = 39) were included in this retrospective cohort study and allocated to DEB-TACE and cTACE groups accordingly. Multiple cTACE treatments history was defined as history of three or more cycles cTACE treatments. Then treatment responses were assessed according to the criteria of modified Response Evaluation Criteria in Solid Tumors (mRECIST), and progression free survival (PFS), as well as overall survival (OS), was calculated. In addition, adverse events and liver function related indexes were recorded. Complete response ( P = .167) was of no difference while objective response rate (ORR) ( P = .003) was increased in DEB-TACE group compared with cTACE group. Patients in DEB-TACE group presented with more favorable PFS ( P = .028) and OS ( P = .037) compared with cTACE group. Further analysis revealed that DEB-TACE (vs cTACE) was an independent predictive factor for better ORR ( P = .001), PFS ( P = .006) and OS ( P = .001). The albumin (ALB) level at first month after treatment was elevated ( P = .015) while the other liver function indexes levels did not vary (all P > .05) in DEB-TACE group compared with cTACE group. The incidences of pain ( P = .327), fever ( P = .171) and nausea/vomiting ( P = .400) during hospitalization were similar between the 2 groups. DEB-TACE is more efficient and equally tolerant compared with cTACE in HCC patients with multiple cTACE treatments history.

Background Primary pulmonary mucosa-associated lymphoma tissue lymphoma is rare and is often misdiagnosed because of its diverse and nonspecific clinical features. The aim of this study was to raise awareness among clinicians and to share our experience of treating and managing such patients. Material/Methods This retrospective study was conducted between 1 January 2009 and 31 October 2017 at the First Affiliated Hospital of Guangxi Medical University. All cases were confirmed via pathology and immunohistochemistry. In addition, we reviewed all relevant literature. Results Altogether, 21 patients (7 female, 14 male) with a median age of 54 (range, 19–84) years were diagnosed with primary pulmonary mucosa-associated lymphoma. Expiratory dyspnea, repeated cough and expectoration, and weight loss were the most common symptoms. Pulmonary lesions were found via physical examination in 10 patients who had no obvious symptoms. Chest computed tomography showed nodules, pulmonary consolidation, bronchial bronchogram, ground-glass opacity, and mediastinal lymph node enlargement. Some patients were misdiagnosed with tuberculosis and pneumonia, while others were initially diagnosed with cancer. Tumor pathology and immunocytochemistry indicated primary pulmonary mucosa-associated lymphoma tissue lymphoma. Six patients underwent chemotherapy, 5 underwent surgery, 4 underwent surgery and chemotherapy, 3 were only observed, and 3 refused treatment. Conclusions The development of primary pulmonary mucosa-associated lymphoid tissue lymphoma is slow and insidious. Having no specific clinical symptoms and imaging findings, it is easily misdiagnosed. Final diagnosis is made via pathologic evaluation and immunohistochemistry. Surgery and chemotherapy are the primary treatment modalities and yield a good prognosis.

The present study aimed to investigate the expression of elongation of very long-chain fatty acids family member 6 (ELOVL6) in hepatocellular carcinoma (HCC) tissues, and to determine its role in the development of HCC. A total of 377 HCC specimens were collected for tissue microarray and immunohistochemistry analyses. The ELOVL6 IHC score for HCC tissues was 0.97±0.71, which was significantly lower than that of the matched adjacent normal tissues (1.32±0.68; P<0.001). Patients with low levels of ELOVL6 expression were older (P=0.014) and possessed larger sized tumors (P=0.039) than patients with high expression levels. Additionally, Kaplan-Meier analysis revealed that patients with low ELOVL6 expression levels also had significantly poorer overall (P<0.001) and disease-free (P=0.029) survival times, and a greater probability of recurrence. The tumor size, tumor-node-metastasis (TNM) stage, vascular invasion and ELOVL6 expression were all shown to be prognostic variables for overall survival in patients with HCC. Multivariate analysis revealed that vascular invasion (P<0.001), TNM stage (P<0.001) and ELOVL6 expression (P=0.001) were independent prognostic variables for overall survival. In addition, vascular invasion (P=0.032) and ELOVL6 expression (P=0.041) were independent risk factors for disease-free survival, and vascular invasion (P=0.019) and ELOVL6 expression (P=0.045) were independent risk factors associated with HCC recurrence. The present study revealed that in patients with HCC, ELOVL6 expression level was reduced in HCC tissues, and that higher ELOVL6 expression levels correlated with longer survival times. This indicates that ELOVL6 may serves as an independent marker of poor patient outcome.
