Abstract
INTRODUCTION Several previous studies have explored whether sex has prognostic significance in patients with small cell lung cancer (SCLC). In this retrospective study, we aimed to show the clinical significance of sex in SCLC patients. METHODS A total of 378 SCLC patients were assessed retrospectively. RESULTS Sixty-one (16.1%) patients were women; 26 of 131 (19.9%) patients had limited disease (LD-SCLC); and 14.2% of patients (35 of 247 patients) had extended disease (ED-SCLC). In all SCLC patients, regardless of stage, female patients were more likely to be nonsmokers (7.7 vs. 1%, p = 0.04 for LD-SCLC; and 11.4 vs. 1.4%, p = 0.001 for ED-SCLC) and more often to be anemic (26.9 vs. 11.4%, p = 0.04 for LD-SCLC; and 45.7 vs. 28%, p = 0.03 for ED-SCLC). While women with LD-SCLC were diagnosed younger (<60) than men (65.4 vs. 37.1%, p = 0.009), they had larger (>5 cm) tumors (69.2 vs. 42.9%, p = 0.01). Moreover, obesity (77.1 vs. 56.4%, p = 0.02) and less weight loss (88.6 vs. 73.6%, p = 0.04) were more common in women with ED-SCLC than in men. However, there were no associations between sex and significant prognostic factors, such as performance status, metastasis site, serum LDH level, response to chemotherapy, and disease recurrence. Outcomes in LD-SCLC patients were found to be similar between sexes; median overall survivals in women compared to men was 18 versus 15 months, respectively (p = 0.8). On the other hand, female patients with ED-SCLC had better survivals; median survivals for women versus men were 10 versus 7 months, respectively (p = 0.008). This significance for female ED-SCLC patients was also maintained in the multivariate analysis (p = 0.001). CONCLUSION While the survival rates of female patients, who constitute a small proportion of SCLC patients, are no different from men in LD-SCLC, they are better in ED-SCLC.

Abstract
OBJECTIVE This study employed time series data to assess long-term changes in the burden of lung cancer (LC) caused by residential radon exposure, an important environmental risk factor, so as to develop evidence-based strategies for future public health management. METHODS Based on the open data from the Global Burden of Disease (GBD 2019) database, we conducted an analysis of the residential radon exposure-caused LC mortality, disability-adjusted life years (DALYs), and corresponding crude rates and age-standardized rates (ASRs) for various age groups. We employed the employed age-period-cohort (APC) model to investigate the age, period, and cohort effects of the data, allowing us to discern the trends in LC disease burden attributable to radon exposure in residential settings over time. RESULTS From 1990 to 2019, age-standardized mortality rates (ASMR) and age-standardized DALYs rates of LC caused by residential radon exposure in China demonstrated an overall increasing trend, with males higher than females. The CMR and crude DALYs rate for males were higher than those for females across all age groups. The APC analysis revealed that the local drift of LC death and DALYs rates in males and females showed a decreasing trend before 60 and an increasing trend after 60. CONCLUSION The persistent presence of residential radon exposure as a crucial risk factor for LC underscores the need for public health authorities and policymakers to take more proactive measures to reduce radon exposure. Particularly, attention should be paid on the elderly population and male patients.

Abstract
(1) Background: There is a difference in the course of lung cancer between women and men. Therefore, there is a need to evaluate various factors in the patient population treated in daily practice. The purpose of this study was to analyze the clinical, sociodemographic and psychological aspects of female lung cancer. To better express the results, we compared women and men. (2) Methods: Consecutive patients with a history of lung cancer treatment admitted to the outpatient oncology clinic (Department of Lung Cancer and Chest Tumours, Maria Skłodowska-Curie National Research Institute of Oncology in Warsaw) and the Department of Internal Medicine, Pulmonary Diseases and Allergy, were enrolled. We conducted analyses of the clinical, psychological and socioeconomic factors of women with lung cancer treated in everyday practice, including a comparison with a group of men. Demographic data were collected from a self-administered questionnaire. We used the Perceived Stress Scale (PSS-10) and Acceptance of Illness Scale (AIS) questionnaires for psychological evaluation. (3) Results: A total of 100 patients with confirmed primary lung cancer with a history of treatment were enrolled in the study (50 women and 50 men). We found a significantly shorter history of smoking in the group of women; at the same time, there were no differences in the reported incidence of COPD. Despite comparable results to men on the psychological questionnaire (PSS-10, AIS), women more often reported a willingness to be supported by a psychologist or psychiatrist due to lung cancer. However, they did not decide to consult them more often than men. Immunotherapy was a significantly less frequently used method in women. (4) Conclusions: We should be more active in finding out the willingness to consult a psychologist or psychiatrist among women with lung cancer. The diagnosis of COPD should be considered more often among women due to the lack of differences in the reported incidence of COPD between men and women, despite a clear contrast in the number of pack-years.

Abstract
The incidence and mortality of lung cancer in women are rising, with both increasing by 124% between 2003 and 2019. The main risk factor for lung cancer is tobacco use, but indoor radon gas exposure is one of the leading causes in nonsmokers. The most recent evidence demonstrates that multiple factors can make women more susceptible to harm from these risk factors or carcinogens. For this consensus statement, the Association for Lung Cancer Research in Women (ICAPEM) invited a group of lung cancer experts to perform a detailed gender-based analysis of lung cancer. Clinically, female patients have different lung cancer profiles, and most actionable driver alterations are more prevalent in women, particularly in never-smokers. Additionally, the impact of certain therapies seems to be different. In the future, it will be necessary to carry out specific studies to improve the understanding of the role of certain biomarkers and gender in the prognosis and evolution of lung cancer.

Gee K, Yendamuri S. Lung cancer in females-sex-based differences from males in epidemiology, biology, and outcomes: a narrative review. Transl Lung Cancer Res 2024; 13:163-178. [PMID: 38405003 PMCID: PMC10891406 DOI: 10.21037/tlcr-23-744] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/15/2023] [Accepted: 01/19/2024] [Indexed: 02/27/2024]
Abstract
Background and Objective The role of biological sex is seldom considered in characterizing lung cancer, the deadliest cancer in both the United States and the world. Lung cancer has traditionally been regarded as a male disease; as such, research in female-specific phenomena is frequently conflicting or absent. Currently, disparities in lung cancer incidence are primarily driven by females, especially non-smokers and those of younger age. This narrative review provides insight into sex-specific characteristics of lung cancer, highlighting risk factors, diagnosis patterns, carcinogenesis, and treatment outcomes in females. Methods The PubMed database was searched on July 26, 2023 to identify research published between 2013 and 2023 in English. Sixty-three articles were considered relevant, and their full texts and citations were studied to compile information for this narrative review. Key Content and Findings Exposure-related risk factors, including personal tobacco use, are thought to impact female lung cancer risk more profoundly. However, studies on occupational exposures are underpowered to conclude risk in females. Data characterizing the effect of endogenous and exogenous hormonal exposures on female lung cancer risk remain two-sided. Screening guidelines are tailored to white males, exacerbating sex and race disparities. The effect of biological sex on carcinogenesis and the immune system response to cancer is not fully understood, though the female immune system clearly reacts more aggressively to lung cancer. In early-stage disease, females have greater survival in the perioperative setting and during follow-up of several years, attributed to favorable histopathology and healthier baseline status. Sex-specific response to systemic treatment continues to be optimized as lack of standardization in randomized trials makes interpreting results difficult when aggregated. Conclusions Biological sex plays a critical role in non-small cell lung cancer (NSCLC), though further study is needed to depict the complex web of factors that affect lung cancer risk, development, and outcomes. Female underrepresentation in studies has contributed to this lack of understanding. As these disparities are eliminated, we can move towards more effective treatment for both sexes in this pervasive yet deadly disease.

Abstract
BACKGROUND Precision medicine in oncology aims to identify the most beneficial interventions based on a patient's individual features and disease. However, disparities exist when providing cancer care to patients based on an individual's sex. OBJECTIVE To discuss how sex differences impact the epidemiology, pathophysiology, clinical manifestations, disease progression, and response to treatment, with a focus on data from Spain. RESULTS Genetic and environmental factors (social or economic inequalities, power imbalances, and discrimination) that contribute to these differences adversely affect cancer patient health outcomes. Increased health professional awareness of sex differences is essential to the success of translational research and clinical oncological care. CONCLUSIONS The Sociedad Española de Oncología Médica created a Task Force group to raise oncologists' awareness and to implement measures to address sex differences in cancer patient management in Spain. This is a necessary and fundamental step towards optimizing precision medicine that will benefit all individuals equally and equitably.

Abstract
Background Long-term changes in lung cancer (LC) patients are difficult to evaluate. We report results from the French KBP-2020 real-life cohort. Methods KBP-2020 was a prospective cohort that included all patients diagnosed with LC in 2020, in nonacademic public hospital in France. Patient and tumour characteristics were described and compared with similarly designed cohorts in 2000 and 2010. Findings In 2020, 82 centers included 8,999 patients diagnosed with LC. The proportion of women increased: 34·6% (3114/8999) compared to, 24·3% (1711/7051) and 16·0% (904/5667) in 2010 and 2000 (p<0·0001). The proportion of non-smokers was higher in 2020 (12·6%, 1129/8983) than in previous cohorts (10·9% (762/7008) in 2010; 7·2% (402/5586) in 2000, p<0·0001). In 2020, at diagnosis, 57·6% (4405/7648) of patients had a metastatic/disseminated stage non-small-cell lung cancer (NSCLC) (58·3% (3522/6046) in 2010; 42·6% (1879/4411) in 2000, p<0·0001). Compared with 2000 and 2010 data, early survival improved slightly. In 2020, 3-month mortality of NSCLC varied from 3·0% [2·2 – 3·8] for localized to 9·6% [8·1 – 11·0] for locally advanced to 29·2% [27·8 – 30·6] for metastatic and was 24·8% [22·3 – 27·3] for SCLC. Interpretation To our knowledge KBP cohorts have been the largest, prospective, real-world cohort studies involving LC patients conducted in worldwide. The trend found in our study shows an increase in LC in women and still a large proportion of patients diagnosed at metastatic or disseminated stage. Funding The study was promoted by the French College of General Hospital Pulmonologists with financial support of industrials laboratories.

Abstract
Background Evidence is limited characterizing sociodemographically diverse patient populations with lung cancer in relation to smoking status. Methods In a cross-sectional analysis of adults diagnosed with lung cancer at ages ≥30 years from 2007-2018 within an integrated healthcare system, overall and sex-specific prevalence of never smoking were estimated according to sociodemographic and clinical characteristics. Adjusted prevalence ratio (aPR) and 95% confidence interval (CI) were also estimated using modified Poisson regression to identify patient characteristics associated with never smoking, overall and by sex. Similar analyses were conducted to explore whether prevalence and association patterns differed between non-Hispanic White and Asian/Pacific Islander patients. Results Among 17,939 patients with lung cancer, 2,780 (15.5%) never smoked and 8,698 (48.5%) had adenocarcinoma. Overall prevalence of never smoking was higher among females than males (21.2% vs. 9.2%, aPR 2.13, 95% CI: 1.98-2.29); Asian/Pacific Islander (aPR 2.85, 95% CI: 2.65-3.07) and Hispanic (aPR 1.72, 95% CI: 1.51-1.95) than non-Hispanic White patients; patients who primarily spoke Spanish (aPR 1.60, 95% CI: 1.32-1.94), any Asian language (aPR 1.20, 95% CI: 1.10-1.30), or other languages (aPR 1.84, 95% CI: 1.27-2.65) than English; patients living in the least vs. most deprived neighborhoods (aPR 1.36, 95% CI: 1.24-1.50); and patients with adenocarcinoma (aPR 2.57, 95% CI: 2.18-3.03), other non-small cell lung cancer (NSCLC) (aPR 2.00, 95% CI: 1.63-2.45), or carcinoid (aPR 3.60, 95% CI: 2.96-4.37) than squamous cell carcinoma tumors. Patterns of never smoking associated with sociodemographic, but not clinical factors, differed by sex. The higher prevalence of never smoking associated with Asian/Pacific Islander race/ethnicity was more evident among females (aPR 3.30, 95% CI: 2.95-3.47) than males (aPR 2.25, 95% CI: 1.92-2.63), whereas the higher prevalence of never smoking associated with living in the least deprived neighborhoods was more evident among males (aPR 1.93, 95% CI: 1.56-2.38) than females (aPR 1.18, 95% CI: 1.06-1.31). Associations between primary language and never-smoking status were found only among females. Overall and sex-specific prevalence and association patterns differed between Asian/Pacific Islander and non-Hispanic white patients. Conclusions Our findings suggest that patterns of never-smoking status associated with sociodemographic and clinical characteristics are different across sex and race/ethnicity among patients with lung cancer. Such data are critical to increasing awareness and expediting diagnosis of this disease.
