Leiomyosarcoma of the rectum is rare. The standard treatment is abdominoperineal resection and, in the past, radiation therapy has been employed in the palliative setting only. The authors report two additional cases of this rare tumor and its treatment using sphincter-preserving surgery and radiation therapy. In selected patients, conservative surgery followed by radiation therapy (brachytherapy with or without external beam radiation) may be an alternative to radical surgery with the goals of local control of the disease and rectal sphincter preservation. However, more experience and longer follow-up are needed before this approach could be recommended routinely.
直肠平滑肌肉瘤较为罕见。标准治疗方法是腹会阴联合切除术，过去放射治疗仅用于姑息治疗。作者报告了另外两例这种罕见肿瘤病例及其采用保留括约肌手术和放射治疗的治疗情况。对于部分患者，保守手术联合放射治疗（近距离放射治疗，可联合或不联合外照射放疗）可能是根治性手术的一种替代方案，目的是局部控制疾病并保留直肠括约肌。然而，在能够常规推荐这种方法之前，还需要更多经验和更长时间的随访。
