Background Cancer cachexia is a clinical manifestation in various advanced cancers that characterized by muscle atrophy and fat loss as its main features; it is frequently associated with systemic inflammatory response. However, the differences in inflammatory response and lipid metabolism of different genders remain unclear. This study explores the difference between cachexic and non-cachexic patients in different genders and cancer types and focus on the plasma inflammation factors levels and lipid metabolism parameters in different genders. Methods We first analyzed the general characteristics in 311 cancer patients between cachexic and non-cachexic patients, with an emphasis on expression levels related to inflammatory factors and lipid metabolism parameters. We then further analyzed these characteristics in different genders and cancer types. Lastly, the correlations between plasma interleukin-6 (IL-6) and lipid metabolism parameters in cachexia patients of different genders were analyzed. Results Among 311 patients, there were 74 cancer cachexia patients (50 males and 24 females) and 237non-cachexia patients (150 males and 87 females). Body mass index (BMI), TNM stage, plasma concentration of hemoglobin, platelet, lymphocyte count, total protein, albumin, prealbumin, total cholesterol, apolipoprotein E (ApoE), free fatty acid (FFA) and IL-6 were significantly different between cachexic and non-cachexic patients (all p  < 0.05). In addition, these characteristics were different in different cancer types. When compared to male non-cachexic patients, male cachexic patients showed a significant increase in plasma levels of IL-6 and platelet, later TNM stage, with marked decrease in their plasma total protein, albumin, prealbumin, ApoE as well as their lymphocyte counts and hemoglobin levels (all p  < 0.05). In comparison with female non-cachexic patients, female cachexic patients’ IL-6 levels and FFA were significantly elevated with noticeable decrease in their BMI, total cholesterol, ApoE and prealbumin, as well as later TNM stage (all p  < 0.05). Correlation analysis revealed that IL-6 levels in female cachexic patients had a significant positive correlation with FFA expression, but this correlation not reflected in male patients. Conclusion This study demonstrates the different metabolic characteristics of male and female cancer cachexia patients. Future study about cancer cachexia should pay attention to different genders and cancer types.

Purpose of reviewAnalyze current evidence on racial/ethnic disparities in cardiovascular outcomes among cancer survivors, identifying factors and proposing measures to address health inequities.Recent findingsExisting literature indicates that the Black population experiences worse cardiovascular outcomes following the diagnosis of both initial primary cancer and second primary cancer, with a notably higher prevalence of cardio-toxic events, particularly among breast cancer survivors. Contributing socioeconomic factors to these disparities include unfavorable social determinants of health, inadequate insurance coverage, and structural racism within the healthcare system. Additionally, proinflammatory epigenetic modification is hypothesized to be a contributing genetic variation factor. Addressing these disparities requires a multiperspective approach, encompassing efforts to address racial disparities and social determinants of health within the healthcare system, refine healthcare policies and access, and integrate historically stigmatized racial groups into clinical research.SummaryRacial and ethnic disparities persist in cardiovascular outcomes among cancer survivors, driven by multifactorial causes, predominantly associated with social determinants of health. Addressing these healthcare inequities is imperative, and timely efforts must be implemented to narrow the existing gap effectively.
