“…It is generally accepted that cigarette smoking may play an important role as carcinogenesis in lung cancer as well as bladder, kidney, and cancer of the renal pelvis [10][11][12][13][14][15]. Although smoking induces all major histological types of lung cancer, the strongest associations are with squamous cell cancer and SCLC [19]. In the present study, 11 of 13 (84.6%) patients were current or former smokers, and nine (69.2%) patients had these two histological types of lung cancer.…”
For patients with urological cancers, smoking cessation, a chest radiograph or CT scan at least yearly and swift evaluation of signs or symptoms that are suggestive of lung cancer should be recommended.

“…Of the various histologic types of lung cancer, epidermoid carcinomas account for about 30% and small cell carcinomas about 20 to 25 % of bronchogenic carcinomas [5] in the general population. In the present study, epidermoid carcinomas and adenocarcinomas constituted a similar (30% and 24%) proportion of lung cancers (Table I).…”
Sixty-seven cases of lung cancer occurring in men aged 75 or older were examined at autopsy. There is a similar incidence of epidermoid and small cell carcinoma, but a lower incidence of adenocarcinoma and a slightly higher incidence of large cell carcinoma in this elderly group of patients compared to the incidence of various histologic types occurring in patients of all ages. The various organs involved by metastatic tumor are similar to those seen in lung cancer in general; the overall metastatic disease is less widespread in the older group.
“…Screening may also be targeted toward cigarette smokers, who account for 80% or more of all diagnosed tumors (65). In the Early Lung Cancer Cooperative Study, the prevalence rate of cancer during the first year of screening over 30,000 male cigarette smokers was 7.6 cases per 1000 (39).…”
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
