The age-correlated survival rates for 982 women treated for localised breast cancer were analysed retrospectively. Analysis by size of the primary cancer showed that those with smaller cancers had a significantly higher survival rate and a significantly reduced probability of dying of cancer. Cured groups of patients were identified for all but those with the smallest tumours--2.0 cm in diameter or smaller. A long period of follow-up (to 25 years) is necessary to establish the presence of a large cured group in such cases.
对982例接受局部乳腺癌治疗的女性的年龄相关生存率进行了回顾性分析。按原发癌大小进行分析显示,癌灶较小的患者生存率显著更高,死于癌症的概率显著降低。除肿瘤直径为2.0厘米或更小的患者外,其他所有患者均确定有治愈组。对于此类病例,需要长时间随访(长达25年)以确定是否存在大量治愈组。
