to present the frequency of different types of cancer in adolescents with 15 and 16-year-old treated at the Instituto Mexicano del Seguro Social (IMSS) in Mexico City (MC) hospitals.
it was an observational and prolective study. During January 1 of 1996 to December 31 of 2005, were analyzed new cases of adolescents of 15 and 16-year-old with malignant neoplasms in adolescents at IMSS. The neo-plasms were grouped according with the International Classification of Childhood Cancer; they were stratified by age, sex, and place of residence, and the frequency of these variables were obtained.
a total of 207 cases were registered. Leukemias were more frequent with 55 cases (26.6%); the second place was for bone tumors with 36 cases (17.4%) and the third place were lymphomas with 32 cases (15.5%). There were not cases of retinoblastoma and renal tumors; only 8 cases of carcinomas (3.9%) were registered. The greatest frequency was observed in males with 116 cases (56.0%), with male/female ratio of 1.3:1. Mexico City and State of Mexico were more frequent places of residence with 70.5% of cases. Near of forty nine percent of cases (48.8%) with solid tumors were diagnosed in III or IV stages.
the pattern of cancer was different from older adolescents (15 to 19-year-old), it is necessary to conduct studies of survey in order to determine epidemiology of cancer in the Mexican adolescents.
呈现墨西哥城墨西哥社会保险局（IMSS）下属医院收治的15至16岁青少年中不同类型癌症的发病频率。
这是一项观察性前瞻性研究。在1996年1月1日至2005年12月31日期间，对IMSS中15至16岁患有恶性肿瘤的青少年新发病例进行分析。肿瘤按照国际儿童癌症分类进行分组；按年龄、性别和居住地进行分层，并得出这些变量的频率。
共登记了207例病例。白血病最为常见，有55例（26.6%）；其次是骨肿瘤，有36例（17.4%），第三位是淋巴瘤，有32例（15.5%）。未出现视网膜母细胞瘤和肾肿瘤病例；仅登记了8例癌症（3.9%）。男性病例最多，有116例（56.0%），男女比例为1.3:1。墨西哥城和墨西哥州是居住频率较高的地区，占病例的70.5%。近49%（48.8%）的实体瘤病例在III期或IV期被诊断出来。
癌症模式与年龄稍大的青少年（15至19岁）不同，有必要开展调查研究以确定墨西哥青少年癌症的流行病学情况。
