Cancers, Vol. 11, Pages 1801: Efficacy of Cancer Immunotherapy: An Umbrella Review of Meta-analyses of Randomized Controlled Trials

We examined publication bias and excess significance bias. 63 articles corresponding to 247 meta-analyses were eligible. Nine meta-analyses were classified to have convincing evidence, and 75 were classified as suggestive evidence. The clinical benefit of immunotherapy was supported by convincing evidence in the following settings: anti-PD-1/PD-L1 monoclonal antibody (mAb) therapy for treating advanced melanoma and non-small cell lung cancer (NSCLC), the combination of rituximab and chemotherapy for treating chronic lymphocytic leukemia and B-cell non-Hodgkin’s lymphoma, adoptive cell immunotherapy for NSCLC, and the combination of interferon α and chemotherapy for metastatic melanoma. A further meta-analysis of 16 RCTs showed that anti-PD-1/PD-L1 mAb therapy had a benefit in patients with solid tumors (overall survival; hazard ratio = 0.73, 95% CI: 0.68–0.79; p < 0.001), supported by convincing evidence. In the future, rigorous approaches are needed when interpreting meta-analyses to gain better insight into the true efficacy of cancer immunotherapy.

This study reviewed the applicability of laparoscopy in this challenging setting.MethodsRetrospective analysis of patients who underwent trans-abdominal re-operative rectal surgery from 2010-2019 was performed.ResultsSeventy-eight patients [35 females (45%); BMI 25kg/m2) were included. Reasons for reoperation were recurrent cancer in 18 (43%) patients and anastomotic failure in 57 (73%). Twenty-two (28%) had laparoscopic surgery and 4 had attempted laparoscopy converted to laparotomy. A higher success rate was noted for laparoscopy with prior laparoscopic surgery. Benefits of laparoscopy included significant reduction in l...

CONCLUSION: Primary Signet ring cell carcinoma of the prostate is a rare and aggressive histological variant of adenocarcinomas of the prostate. Treatment is the same as classical adenocarcinoma with an emphasis on aggressive multimodal treatment. PMID: 31797810 [PubMed - in process]

Authors: Yalcin S, Kaya E, Ebiloglu T, Akay S, Zor M, Sarıkaya S, Yilmaz S, Bedir S Abstract OBJECTIVES: In this research, we designed a cognitive fusion(CF) prostate biopsy(PB) (CFPB) technique by examining the multiparametric MRI of prostate (MP_MRI-P) images in a smart-phone near the trans-rectal ultrasound (TRUS) device, and examined the results. METHODS: Between January 2011 and January 2017, a total of 344 men who had PB enrolled in this study. Group 1 had a minimum of a 12-core standard TRUS PB (TRUSPB). Group 2 had CFPB while examining the MP_ MRI-P images in a smartphone near the TRUS device. A minimu...

Authors: Murray NP, Aedo S, Fuentealba C, Salazar A, Reyes E, Lopez MA, Minzer S Abstract INTRODUCTION: Minimal residual disease (MRD) is that which persists after curative treatment for prostate cancer. It has the potential to grow and cause metastasis. The detection of circulating prostate cells (CPCs) and bone marrow micro-metastasis could represent different sub-types of MRD. OBJECTIVE: To determine biochemical failure free survival and time to failure, the presence of circulating prostate cells and bone marrow micro-metastasis in men treated for low risk prostate cancer. HYPOTHESIS: The presence of MRD...

CONCLUSION: Video-endoscopic inguinal lymphadenectomy contributes to less morbidity with a lower- rate of cutaneous complications and less severity. Furthermore, VEIL gives lower hospital stay without changing in initial oncologic outcomes. Although we need longer series to stablish the oncologic long-term results.

Today's open access research on tryptophan and its role in age-related immune dysfunction is particularly interesting in the context of ongoing research into the changes that take place in gut microbiota with age. Other recent work has examined the way in which tryptophan production by gut microbes declines precipitously with age, as this is one of a number of compounds produced by bacteria, such as butyrate, indole, and proprionate, that are influential on long term health. It is a slow process, but researchers are uncovering the specific mechanisms linking age-related changes in gut microbe populations with declining hea...

Markus Hartl* and Rainer Schneider Center of Molecular Biosciences (CMBI), Institute of Biochemistry, University of Innsbruck, Innsbruck, Austria The neuronal proteins GAP43 (neuromodulin), MARCKS, and BASP1 are highly expressed in the growth cones of nerve cells where they are involved in signal transmission and cytoskeleton organization. Although their primary structures are unrelated, these signaling proteins share several structural properties like fatty acid modification, and the presence of cationic effector domains. GAP43, MARCKS, and BASP1 bind to cell membrane phospholipids, a process reversibly regulate...
