An investigation of over- and under-registration of uterine sarcomas in the Swedish Cancer Registry during the period 1958-1980 was carried out. A histopathologic review of a 10% sample (159 cases) revealed that 18% of the cases, the majority of which were benign leiomyomas, could not be reclassified as sarcomas. All 186 cases of uterine sarcoma treated at Radiumhemmet during the period 1958-1980 were found in the Cancer Registry, but only 90% as sarcomas. As a consequence of over- and under-registration of the sarcoma tumors, the estimated incidences will be affected. In this study, however, we could not find any time trend in the erroneous registration, which implies that comparisons in incidence over time would still be valid.
对1958年至1980年期间瑞典癌症登记处子宫肉瘤登记过多和登记不足的情况进行了调查。对10%的样本（159例）进行组织病理学复查发现，18%的病例（其中大多数为良性平滑肌瘤）无法重新分类为肉瘤。1958年至1980年期间在镭疗医院接受治疗的所有186例子宫肉瘤病例在癌症登记处均有记录，但仅90%被登记为肉瘤。由于肉瘤肿瘤的登记过多和登记不足，估计发病率将受到影响。然而，在本研究中，我们未发现错误登记存在任何时间趋势，这意味着发病率随时间的比较仍然有效。
