Background We previously showed that therapy with anti–checkpoints T-lymphocyte-associated protein 4 (anti–CTLA-4) or antiprogrammed cell death protein 1 (anti–PD-1) agents was more effective for men as compared with women. However, because the sex-dimorphism of the immune system is complex, involving multiple elements of immune responses, it is possible that women could derive larger benefit than men from strategies other than therapy with immune checkpoint inhibitors (ICIs) alone. Here we investigated whether women could derive larger benefit than men from the combination of chemotherapy and anti-PD-1 or anti-PD-L1. Methods We performed two meta-analyses. The first included all randomized controlled trials (RCTs) testing anti-PD1 and anti–PD-L1 plus chemotherapy vs chemotherapy to assess different efficacy between men and women. The second included all RCTs of first-line systemic treatment in advanced non-small cell lung cancer testing anti–PD-1/PD-L1 given either alone or combined with chemotherapy to assess the different efficacy of these two immunotherapeutic strategies according to patients’ sex. For each RCT included in the two meta-analyses, first, a trial-specific ratio of hazard ratios (HRs) was calculated from the ratio of the reported hazard ratios in men and in women; second, these trial-specific ratios of hazard ratios were combined across trials using a random-effects model to obtain a pooled hazard ratios ratio. A pooled HRs ratio estimate lower than 1 indicates a greater treatment effect in men, and higher than 1 a greater effect in women. Results Eight RCTs were included in the first meta-analysis. The pooled overall survival hazard ratios (OS-HRs) comparing anti–PD-1/PD-L1 plus chemotherapy vs chemotherapy was 0.76 (95% confidence interval [CI] = 0.66 to 0.87) for men and 0.48 (95% CI = 0.35 to 0.67) for women. The pooled ratio of the overall survival hazard ratios reported in men vs women was 1.56 (95% CI = 1.21 to 2.01), indicating a statistically significant greater effect for women. Six RCTs were included in the second meta-analysis: three tested an anti-PD-1 alone, whereas three RCTs tested anti-PD-1/PD-L1 plus chemotherapy. The pooled overall survival hazard ratios were 0.78 (95% CI = 0.60 to 1.00) in men and 0.97 (95% CI = 0.79 to 1.19) in women for anti–PD-1 alone, compared with 0.76 (95% CI = 0.64 to 0.91) in men and 0.44 (95% CI = 0.25 to 0.76) in women for anti–PD-1/PD-L1 plus chemotherapy. The pooled ratio of overall survival hazard ratios was 0.83 (95% CI = 0.65 to 1.06) for anti–PD-1 alone, indicating a greater effect in men, and 1.70 (95% CI = 1.16 to 2.49) for anti–PD-1/PD-L1 plus chemotherapy, indicating a greater effect in women. Conclusion Women with advanced lung cancer derived a statistically significantly larger benefit from the addition of chemotherapy to anti–PD-1/PD-L1 as compared with men.

The study provides an estimator of risk of LAEs in LQTS that allows a granular estimate of 5-year arrhythmic risk and demonstrate the superiority of nadolol in reducing the risk of LAEs in LQTS.

Purpose We previously demonstrated that sex influences response to immune-checkpoint inhibitors. Here we investigate sex-based differences in the molecular mechanisms of anticancer immune-response and immune evasion in patients with NSCLC. Experimental Design We analyzed a) transcriptome-data of 2575 early-stage NSCLCs from 7 different datasets; b) 327 tumor-samples extensively characterized at the molecular level from the TRACERx lung study; c) two independent cohorts of respectively 329 and 391 patients with advanced NSCLC treated with anti-PD1/anti-PDL1 drugs. Results As compared with men, the tumor microenvironment (TME) of women was significantly enriched for a number of innate and adaptive immune cell-types, including specific T-cell subpopulations. NSCLCs of men and women exploited different mechanisms of immune evasion. The TME of females was characterized by significantly greater T-cell dysfunction status, higher expression of inhibitory immune-checkpoint molecules and higher abundance of immune-suppressive cells, including Cancer Associated Fibroblasts, MDSCs and Regulatory T-cells. By contrast, the TME of males was significantly enriched for a T-cells excluded phenotype. We reported data supporting impaired neoantigens presentation to immune system in tumors of men, as molecular mechanism explaining the findings observed. Finally, in line with our results, we showed significant sex-based differences in the association between TMB and outcome of patients with advanced NSCLC treated with anti-PD1/PDL1 drugs. Conclusions We demonstrated meaningful sex-based differences of anticancer immune response and immune evasion mechanisms, that may be exploited to improve immunotherapy efficacy for both women and men.

After a steady increase between the 1950s and the 1970s, laryngeal cancer mortality has been levelling off since the early 1980s in men from most western and southern European countries and since the early 1990s in central and eastern Europe. To update trends in laryngeal cancer mortality, we analyzed data provided by the World Health Organization over the last two decades for 34 European countries and the European Union (EU) as a whole. For major European countries, we also identified significant changes in trends between 1980 and 2012 using joinpoint regression analysis. Male mortality in the EU was approximately constant between 1980 and 1991 (annual percent change, APC=−0.5%) and declined by 3.3% per year in 1991–2012. EU age‐standardized (world population) rates were 4.7/100,000 in 1990–91 and 2.5/100,000 in 2010–2011. Rates declined in most European countries, particularly over the last two decades. In 2010–11, the highest male rates were in Hungary, the Republic of Moldova, and Romania (over 6/100,000), and the lowest ones in Finland, Norway, Sweden, and Switzerland (below 1/100,000). In EU women, mortality was stable around 0.29/100,000 between 1980 and 1994 and slightly decreased thereafter (APC=−1.3%; 0.23/100,000 in 2000–01). We also considered male incidence trends for nine European countries or cancer registration areas. In most of them, declines were observed over recent decades. Laryngeal cancer mortality thus showed favourable trends over the last few decades in most Europe, following favourable changes in tobacco and, mostly for Mediterranean countries, alcohol consumption.
