局部热消融在NSCLC中的临床应用现状与挑战

非小细胞肺癌(non-small cell lung cancer, NSCLC)是原发性肺癌的主要类型,手术切除、放化疗、靶向治疗及免疫治疗等是其主要的治疗模式。近年来,热消融在各期NSCLC的临床应用中受到越来越多的关注。热消融作为一种安全、高效的局部治疗手段,合理的临床应用可以给NSCLC患者带来更多的临床获益。然而其在NSCLC中的应用仍然存在许多尚待研究探讨的问题。本文对近年来热消融在NSCLC中的应用现状作以综述,旨在探讨目前存在的争议问题和未来研究方向。

Effect of pelvic floor rehabilitation technique in preventing the postpartum pelvic floor dysfunction

Objective:To explore the effect of pelvic floor rehabilitation technique in preventing the postpartum pelvic floor dysfunction and on the sexual life quality.Methods:A total of 286 puerpera with pelvic floor dysfunction who were admitted in our hospital from May, 2014 to May, 201542 d after delivery were included in the study, and randomized into the treatment group and the control group with 143 cases in each group. After guidance, the puerpera in the control group were given pelvic floor muscle training by themselves at home. On this basis, the puerpera in the treatment group were treated by the pelvic floor rehabilitation apparatus. The puerpera in the two groups were treated for 4 weeks. The pelvic floor function before treatment, 6 months and 1 year after delivery was detected. The color Doppler ultrasound apparatus was used to detect BSD, PUVA, UVJ-M, and BND 3 months after delivery.Results:BND, PUVA-R, PUVA-S, and UVJ-M 3 months after delivery in the treatment groups were significantly lower than those in the control group, while BSD-S was significantly higher than that in the control group. The improvement of type I and Ⅱ muscle fiber fatigue (%), POP-Q degree, AP indication point (cm), and vaginal dynamic pressure (cmH2O) was significantly superior to that in the control group. The comparison of pelvic floor muscle strength classification before treatment between the two groups was not statistically significant. After treatment, the pelvic floor muscle in the two groups was significantly strengthened, and the proportion of V grade patients was significantly increased when compared with before treatment.Conclusions: The postpartum early pelvic floor rehabilitation technique can effectively enhance the pelvic floor function, and prevent the postpartum pelvic floor dysfunction, with an accurate efficacy;therefore, it deserves to be widely recommended in the clinic.

Organ-specific efficacy in advanced non-small cell lung cancer patients treated with first-line single-agent immune checkpoint inhibitors

Background:Response to immune checkpoint inhibitors(ICIs)is affected by multiple factors.This study aimed to explore whether sites of metastasis are associated with clinical outcomes of ICIs in advanced non-small-cell lung cancer(NSCLC)patients.Methods::The data of NSCLC patients with high programmed death-ligand 1 expression and good performance status receiving first-line ICIs monotherapy from Guangdong Provincial People’s Hospital between May 2019 and July 2020 were retrospectively analyzed.Metastatic sites included liver,bone,brain,adrenal gland,pleura,and contralateral lung.Progression-free survival(PFS)and overall survival(OS)were compared between different metastatic sites and metastatic burden by the Kaplan-Meier method.Organ-specific disease control rate(OSDCR)of different individual metastatic sites was evaluated.Results:Forty NSCLC patients meeting the criteria were identified.The presence of liver metastasis was significantly associated with shorter PFS(3.1 vs.15.5 months,P=0.0005)and OS(11.1 months vs.not reached,P=0.0016).Besides,patients with bone metastasis tend to get shorter PFS(4.2 vs.15.5 months,P=0.0532)rather than OS(P=0.6086).Moreover,the application of local treatment could numerically prolong PFS in patients with brain metastasis(15.5 vs.4.3 months,P=0.1894).More metastatic organs involved were associated with inferior PFS(P=0.0052)but not OS(P=0.0791).The presence of liver metastasis or bone metastasis was associated with more metastatic organs(Phi[φ]:0.516,P=0.001).The highest OSDCR was observed in lung(15/17),and the lowest in the liver(1/4).Conclusions:Metastases in different anatomical locations may be associated with different clinical outcomes and local tumor response to ICIs in NSCLC.ICIs monotherapy shows limited efficacy in patients with liver and bone metastasis,thus patients with this type of metastasis might require more aggressive combination strategies.
