Purpose: To determine the efficacy of acupuncture on the management of hormone therapy–related side effects in breast cancer patients. Methods: Randomized controlled trials of acupuncture versus a control or placebo in breast cancer patients that examined reductions in therapy-related side effects were retrieved from PubMed, EMBASE, Web of Science, and the Cochrane Library through April 2020. Data on patient symptoms (hot flashes, fatigue, pain, stiffness, and gastrointestinal symptoms), physical capacity, cytokines, and general psychosomatic well-being were analyzed. We evaluated and analyzed the quality of all included studies with the 5.2 Cochrane Handbook standards using Stata software (version 10.0) and Revman software (version 5.2), respectively. We assessed the risk of bias using the Cochrane Risk of Bias tool and evaluated the quality of evidence using the GRADE (Grading of Recommendations, Assessment, Development, and Evaluations) approach. Results: The pooled results suggested that acupuncture led to moderate improvements in hot flashes, fatigue, and stiffness. No significant differences were observed in pain, gastrointestinal symptoms, Kupperman index scores, Overall quality of life, tumor necrosis factor levels, and interleukin levels. Conclusions: Evidence for outcome indicators of symptom management were downgraded by the GRADE system for inconsistency, indirectness, and imprecision in the included RCTs. Nonetheless, acupuncture is a moderately appropriate alternative therapy for hormone therapy–related side effects in breast cancer patients. However, it still lacks large-sample, multicenter, prospective RCTs. Future research should focus on standardizing comparison groups and treatment methods, be at least single-blinded, assess biologic mechanisms, have adequate statistical power, and involve multiple acupuncturists.
As new members of the CD28/B7 costimulatory superfamily, PD-1 (programmed cell death 1) and its ligand PD-L1 (programmed cell death ligand 1) mediate a negative costimulatory signal, which inhibits functioning and proliferation of T and B cells, and reduce interleukin-2, interleukin-10, and interferon-γ secretion. This inhibitory pathway plays an important role in immune escape and the microenvironment of the tumor, and closely related to tumor progression. sPD-1 and sPD-L1 are the soluble form of PD-1 and PD-L1 in peripheral blood, which had not been well investigated. In this study, sPD-1 and sPD-L1 level in peripheral blood of non–small cell lung cancer (NSCLC) patients were determined, and their correlation to clinicopathologic features and long-term survival of these patients were analyzed, so as to provide references for further investigations. Plasma sPD-1 and sPD-L1 levels in 88 NSCLC patients and 40 healthy controls were determined by enzyme-linked immunosorbent assay, and their correlation to clinicopathologic features and long-term survival of these patients were analyzed. Our study showed that the plasma sPD-1 and sPD-L1 were higher in NSCLC patients than in healthy controls, and plasma sPD-L1 and sPD-L1/sPD-1 ratio independently and positively correlated with overall survival of NSCLC patients. This study provides a reference for the assessment of prognosis and risk stratification for NSCLC patients, as well as for immune treatment of cancer.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
