肺癌是北美癌肿病人的主要死亡原因,绝大部分发生于老年人,但年轻病人仍约占1～5%。本文报道英国哥伦比亚癌症控制署处理40岁以下病人中各型肺恶性病的经验,并结合现有文献就其特点和可能的治疗方式扼要加以分析。从1969～1979的10年间,共治疗4,516例肺癌病人,其中101例在40岁以下,发生率为2.24%,男65女36(1.75:1),平均年龄为36.2±3.9岁,最年轻者为18岁。除13例外,其余均有大量吸烟史(87%)。半数病人有家族癌症史。仅8例无症状的病人是在胸部X线检查时发现的,其余病人最为常见的症状是咳嗽、咯血和胸痛。29例的颈、腋部淋巴结可触及,12例有杵状指。右侧肺癌53例,左侧49例(1例支气管肺泡癌为双侧受累)。从出现症状至明确诊断的时 Lung cancer is the leading cause of death in patients with cancer in North America. The vast majority occur in the elderly, but young patients still account for about 1 to 5%. This article reports on the experience of the British Columbia Cancer Control Agency in dealing with various types of lung malignancies in patients under the age of 40, and combines current literature with a brief analysis of its characteristics and possible treatment modalities. During the 10 years from 1969 to 1979, a total of 4,516 lung cancer patients were treated, of which 101 were under the age of 40, the incidence was 2.24%, male 65 females 36 (1.75:1), the average age was 36.2±3.9 years old, the youngest It is 18 years old. Except for 13 exceptions, there was a large amount of smoking history (87%). Half of the patients had a family history of cancer. Only 8 asymptomatic patients were found during chest X-ray examination. The most common symptoms in the remaining patients were cough, hemoptysis, and chest pain. In 29 cases, cervical and axillary lymph nodes were palpable, and 12 cases had clubbed fingers. There were 53 cases of lung cancer on the right and 49 cases on the left (1 case of bronchial alveolar carcinoma with bilateral involvement). From symptom onset to definitive diagnosis
