The optimal management of early squamous cell carcinoma of the anal canal (AC) is yet to be determined. This study investigated current practice in the management of early AC.
A patterns of care survey was completed by Australian surgeons and radiation oncologists. Specific topics addressed were as follows: geographical location of practice, staging of disease, treatment approaches to T1N0 tumours and grade 3 anal intra-epithelial neoplasia (AIN3) lesions, radiotherapy planning, toxicities, follow-up and clinical trial involvement.
Sixty-four responses were obtained. For the management of T1N0 disease, half the respondents recommended standard dose chemo-radiotherapy (CRT) and one third recommended wide local excision (WLE). For the management of AIN3, half recommended WLE while a quarter advocated observation.
This study reveals a significant variation in the management of early AC. The development of guidelines specific to the treatment of early AC could standardise treatment while further research is required to define the optimal management of T1N0 AC and AIN.
肛管早期鳞状细胞癌(AC)的最佳治疗方案尚未确定。本研究调查了早期AC治疗的当前实践情况。
澳大利亚外科医生和放射肿瘤学家完成了一项治疗模式调查。涉及的具体主题如下:执业地理位置、疾病分期、T1N0肿瘤及3级肛管上皮内瘤变(AIN3)病变的治疗方法、放射治疗计划、毒性反应、随访及参与临床试验情况。
共获得64份回复。对于T1N0疾病的治疗,一半的受访者推荐标准剂量放化疗(CRT),三分之一的受访者推荐局部广泛切除(WLE)。对于AIN3的治疗,一半的受访者推荐WLE,四分之一的受访者主张观察。
本研究揭示了早期AC治疗存在显著差异。制定针对早期AC治疗的指南可使治疗标准化,同时需要进一步研究以确定T1N0 AC和AIN的最佳治疗方案。
