Lung Cancer in Women-Sociodemographic, Clinical and Psychological Characteristics with Comparison to Men.

(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 Sklodowska-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.

Sex differences in clinico-pathologic characteristics and long-term survival among 17,192 surgically treated NSCLC patients: Nationwide population-based propensity score-matching study.

INTRODUCTION: More information is needed on gender differences in lung cancer surgery. Thus, we conducted a retrospective study on thoracic treatment of non-small cell lung cancer (NSCLC) patients between 2007 and 2020 in Poland. The aim was to characterize sex differences in survival after complete surgical resection and to compare postoperative complications between Polish men and women. The main aspects that were compared between women and men were as follows: type of surgery and postoperative staging, morbidity and mortality, thoracic surgery complications, comorbidities, and overall survival based on a univariate analysis including propensity score matching (PSM) and a multivariate analysis. MATERIALS AND METHODS: Data were collected retrospectively from the Polish Lung Cancer Study Group database. Patients who were surgically treated for NSCLC between 2007 and 2020 (n = 17,192) were included in the study. RESULTS: The univariate analysis showed significantly better survival in women than in men. Women had better 5-year survival compared to men both for adenocarcinoma and squamous cell carcinoma (66% vs. 53%, p < 0.0001 and 65% vs. 51%, p<0.0001%, respectively), for both smokers and non-smokers (65% vs. 52%, p < 0.0001 and 65% vs. 51%, p < 0.0001, respectively), all age groups, and all stages (IA1 to III B). In the PSM analysis, statistically significant differences in favor of women were found for lower lobectomy (67% vs. 50%, p < 0.0001) and upper lobectomy (67% vs. 56%, p < 0.0001). Overall, postoperative complications occurred in 33.1% of patients and were observed more often in men than in women (35.8% vs. 28.6%, p < 0.001). CONCLUSIONS: Women with NSCLC who were treated surgically had a better long-term outcome compared to men, with no significant difference in disease severity. In addition to gender, the histological type, comorbidities, and type of surgery and surgical approach are also important.

The clinico-pathological characteristics of surgically treated young women with NSCLC.

Background: Non-small cell lung cancer diagnosed in young patients is rare. Younger patients with lung cancer are mostly female and have a more advanced stage at initial diagnosis. To our knowledge, no studies have compared single-surgical treatment in different age groups among women. Our study aimed to elucidate the clinicopathological characteristics and the best strategies for surgically treating young women with non-small-cell lung cancer. Methods: The data were collected retrospectively from the Polish Lung Cancer Study Group database. Women who were surgically treated for non-small-cell lung cancer between 2007 and 2020 were included in the study. The participants (n=11,460) were divided into two subgroups: aged ≤55 and >55 years. Results: Statistically significant differences were found for grades IB, IIA, IIIA, and IIIB (22.8% vs. 24.5%, 5.3% vs. 7.5%, 19.3% vs. 15.8%, 5.8% vs. 3.2%, for younger and older women, respectively, all P<0.001). The univariate analysis showed a higher percentage of 5-year survival in the group of younger women than in older women (0.67 vs. 0.64, P=0.00076). Regarding the stage of advancement, statistically significant differences in survival were found for stages IA1, IA2, and IIIA (0.95 vs. 0.86, P=0.047; 0.88 vs. 0.79, P=0.003; 0.5 vs. 0.42, for younger and older women, respectively, all P=0.01). Postoperative complications were more common in older than younger women (27.6% vs. 23.1%, P<0.001). However, there were no statistically significant differences in the number of hospitalization days since surgery and postoperative 30-day mortality. Conclusions: Younger women treated surgically were characterized by a lower percentage of comorbidities, were treated in a more advanced stage of the disease and had a lower percentage of postoperative complications, which, however, did not affect the hospitalization time. Despite the more advanced stage of the disease, survival in selected stages was much better than in the group of older women.

Lung cancer in women in 21th century.

Lung cancer is the first cause of death from malignant disease. The distressing epidemiological data show the increasing female to male incidence ratio for this tumor. A high incidence of lung cancer in never smokers with importance of environmental agents makes a problem among women. Adenocarcinoma (ADC) is noted in women with increasing rate and ethnic background impacts female lung cancer with differences in the incidence of genetic aberrations. The conception of different hormonal status is taken into consideration as potential explanation of variant cancer biology and clinical manifestation in women and men. The impact of 17-ß-estradiol, estrogen receptors, aromatase expression, pituitary sex hormones receptors in carcinogenesis with relation between estrogens and genetic aberrations are investigated. The response to newest therapies among female is also different than in men. This overview summarizes currently available evidence on the specificity of female lung cancer and presents the direction of necessary studies.

Smoking status in relation to obstructive sleep apnea severity (OSA) and cardiovascular comorbidity in patients with newly diagnosed OSA.

INTRODUCTION: the relationship between smoking and sleep disturbance has been well documented. Smoking is a common risk factor for both obstructive sleep apnea (OSA) and cardiovascular diseases. The study aimed to: 1) evaluate the incidence of newly diagnosed OSA in patients presenting with symptoms suggestive of a sleep disorder, 2) assess the relation between smoking status and OSA severity; and 3) compare the prevalence of cardiovascular comorbidities in ever- and never smokers with newly diagnosed OSA. MATERIAL AND METHODS: a retrospective analysis of 5,353 patients suspected of OSA was performed. OSA was diagnosed on the basis of polysomnography. The influence of smoking status on indices of OSA severity was evaluated and the incidence of self-reported cardiovascular diseases and diabetes mellitus type 2 was analyzed in relation to smoking history. RESULTS: OSA was diagnosed in 3,613 patients (67.5%); of these, 21.6% were ever-smokers. Smokers with OSA had a higher apnea-hypopnea index [AHI; 31 (18.4-53.29) vs 29 (18.3-47.7), p = 0.03], lower mean oxygenation during sleep [92 (90-93) vs 92 (91-94), p < 0.01] and a higher daytime sleepiness (Epworth Sleepiness Scale score 11.7 ± 5.5 vs 11.0 ± 5.5, p < 0.001). The most frequent comorbidity was hypertension, followed by obesity, diabetes mellitus type 2 and coronary artery disease, with a statistically higher incidence of hypertension in non-smokers (59.2 vs 64.7 %, p = 0.005). CONCLUSION: smoking is related with OSA severity and increased daytime sleepiness. Our study confirmed the elevated frequency of cardiovascular comorbidities in OSA patients in general but did not show an increased incidence of these comorbidities in smokers.
