The 5-year survival of women with localized (early-stage) cervical cancer is much higher than for women with non-localized (late-stage) cancer, but women with localized cancer tend also to be younger than those with advanced cancer. A new method of presenting the long-term survival is suggested, and the registrations of cervical cancers in South Wales are analysed in terms of average age at registration and average age at death. The observed average age at death was very close to 59 years regardless of stage (and age) at diagnosis, and calculations of expected ages at death of the whole populations suggest that more than half the advantage in survival shown by early stage cancers over late stage cancers is due to diagnosis of the former in younger women.
局限性（早期）宫颈癌女性的5年生存率远高于非局限性（晚期）癌症女性，但局限性癌症女性往往也比晚期癌症女性年轻。本文提出了一种呈现长期生存率的新方法，并根据登记时的平均年龄和死亡时的平均年龄对南威尔士宫颈癌登记情况进行了分析。无论诊断时的阶段（和年龄）如何，观察到的死亡平均年龄都非常接近59岁，对整个人口预期死亡年龄的计算表明，早期癌症相对于晚期癌症在生存率上表现出的优势，超过一半是由于前者在年轻女性中被诊断出来。
