The aim of this study was to evaluate the safety and effectiveness of erlotinib plus DC/CIK in maintenance therapy of advanced non-small cell lung cancer. After 4 cycles of the 2-drug regimen treatment with platinum, the 54 patients with non-small cell lung cancer in phase IIIb or IV reached stable or beyond stable stages. The patients were then randomly divided into 2 groups. One group was treated with erlotinib therapy (erlotinib group), and the other was treated with DC/CIK plus erlotinib (DC/CIK plus erlotinib group). The progression-free survival of the erlotinib group and the DC/CIK plus erlotinib group was 3.98 months (95% CI, 3.56-4.40) and 5.02 months (95% CI, 4.32-5.72) (P=0.002), respectively. The median overall survival of the erlotinib group and the DC/CIK plus erlotinib group was 9.9 months (95% CI, 9.1-10.6) and 10.5 months (95% CI, 9.6-11.4) (P=0.29), respectively. The levels of CD3, CD4, and CD8 were significantly different before and after the treatment in the DC/CIK plus erlotinib group, but not in the erlotinib group. There was no significant difference in toxicity between the 2 groups. In conclusion, there was no statistically significant difference in overall survival between DC/CIK plus erlotinib and erlotinib as maintenance therapy. DC/CIK plus erlotinib was well tolerated with a manageable safety profile.

Acute lung injury (ALI) is a systemic inflammatory process. A large number of studies have shown that astaxanthin (ASTA) has strong anti-inflammatory effect, and almost non-toxic side effects. The purpose...

BackgroundRenal cell carcinoma (RCC) is a disease of genomic alterations, of which the complete panorama helps in facilitating molecular-guided therapy. Germline mutation profiles and associated somatic and clinical characteristics remains unexplored in Chinese RCC patients.MethodsWe retrospectively profiled the germline and somatic mutations of 322 unselected RCC patients using a panel consisting of 808 cancer-related genes. We categorized patients into three groups based on germline mutation status and compared the somatic mutation spectrum among different groups.ResultsApproximately one out of ten (9.9%) RCC patients were identified to carry pathogenic/likely pathogenic (P/LP) germline variants (PGVs), of which 3.7% were variants in syndromic RCC-associated genes and 6.2% were other cancer-predisposition genes. The most common PGV was found in VHL (2.2%), followed by FH, TSC2, ATM, BRCA1, NBN, and BLM (0.6% each). Young patients (≤46 years) were more likely to harbor PGVs. Variants in syndromic RCC-associated genes were predominant identified in young patients, while variants in other cancer-predisposition genes were found in patients >46 years more frequently. Furthermore, 39.3% (11/28) of patients carrying PGVs were detected to have somatic “second hit” events. Germline and somatic sequencing, including microsatellite instability (MSI) status analysis, provided potentially actionable therapeutic targets in 17.1% of patients in the whole cohort.ConclusionsOur results revealed that approximately 10% of RCC patients carried clinically significant germline mutations. Current guidelines recommendation for genetic testing seemed not sensitive enough to identify patients with hereditary RCC susceptibility. It is rational to promote genetic testing in RCC population.

Objective: Our study investigated the immunity changes and life quality changes after the treatment of cytokine induced killer (CIK) cells for patients with malignant tumor after radiochemotherapy, and explored the therapeutic effects of CIK cells on these patients. Methods: Thirty-one patients with malignant tumor after radiochemotherapy were treated with CIK cells. Before and after CIK cells being transfused back, the immunity indexes of the peripheral blood of these cases were detected and the changes of life quality of these cases were compared. Results: After radiochemotherapy, the percentage of CD3+, CD4+ cells declined, the percentage of CD8+ cells rose; the ratio of CD4+/CD8+ declined, and the percentage of CD16+, CD56+ cells declined. As all the above indexes compared with that of normal people, the difference was significant (P < 0.05). After CIK cells therapy, the above indexes improved (P < 0.05). Life quality improved significantly after CIK cells therapy (P < 0.05). Conclusion: Radiochemotherapy can inhibit the immunity in patients with malignant tumor. CIK cells therapy is safe and effective. It may improve the recent immunity and life quality of the patients, which suggesting that it may be an alternative maintenance treatment for patients with malignant tumor after radiochemotherapy.
