22、病变,进一步胸部 CT 显示大疱性肺气肿,同时右肺中叶结节改变,同时患者还携带有烟草,活检证实右肺中叶为非小细胞肺癌,这张胸部 CT 展示的吸烟相关性肺部疾病。临床医生在工作中应宣传吸烟的危害,鼓励戒烟。 肺癌是最常见的恶性肿瘤之一,近年来我国肺癌的发生率呈明显上升的趋势,部分地区肺癌的发病率和死亡率已占各种恶性肿瘤的首位。预计到 2025 年我国每年死于肺癌的人数将接近 100 万,肺癌的发病年龄主要在 40 到 80 岁之间, 70 岁为高峰,男性居多。但是近年来肺癌的发病年龄较前明显提高,有学者提出肺癌的发病年龄较前提高 5 到 10 岁,临床上也偶然能够看到 20 岁到 30 岁之间的

23、肺癌患者。同时女性的发病率也较前增加,其增长速度要快于男性的发病率。 二、肺癌的病理及临床表现 (一)病理类型 病理及临床表现和影像学是一致的,不同的病理类型其选择的治疗方案和预后也是不同的。通常分为非小细胞癌和小细胞肺癌,其中非小细胞肺癌在我国大约占肺癌的 80% ,它还分为鳞癌、腺癌和大细胞未分化癌,其中鳞癌最常见,约占 40% ,多发生在段支气管, 80% 发生于男性,生长较慢,转移较晚。腺癌占 30% ,以女性较为多见,多发生在外围小支气管,其发展速度快慢悬殊。大细胞未分化癌多发生在肺的外周,恶性程度较高,以前它的发生率仅次于鳞癌,但随着腺癌的发病率增加,相应其发病率较前降低。小细胞肺
