[Primary lung cancer in patients under 40 years of age].
There seems to be a resistance of patients and physicians towards aggressive diagnostic evaluation of the symptoms of lung cancer in young people. We here review nine series of young patients with primary lung cancer. Patients below 40 years of age represent between 1.2 and 5% of the total lung cancer population. The distribution of sex and histopathologic findings is different, there being more women, fewer cases of squamous cell and more cases of small anaplastic and adenocarcinoma in the young group. Between 87 and 96% are smokers. There is a delay from the debut of symptoms to the first contact with a general physician of 2.4 to 10.8 months. There is a wide variation concerning tendency to operate with a frequency of curative resection of between 15 and 57%. Based on the survival of young patients who are treated by curative surgical resection, the outcome of surgical treatment for young patients does not differ from the general experience concerning resection in patients of all ages. Young patients who are found inoperable have worse survival than the older patients. Seventy to 90%, more than in the group of patients of all ages, have stadium II or III at the time of diagnosis. In conclusion, physicians should be aggressive with respect to the diagnostic evaluation even of young patients with symptoms suggestive of lung cancer.
