Clinical Audit of the Radiotherapy Process in Rectal Cancer: Clinical Practice guidelines and Quality Certification Do Not Avert Variability in Clinical Practice

# metadata.dc.description.abstract[].value
Background: The therapeutic approach to cancer is complex and multidisciplinary. Radiotherapy is among the essential treatments, whether used alone or in conjunction with other therapies. This study reports a clinical audit of the radiotherapy process to assess the process of care, evaluate adherence to agreed protocols and measure the variability to improve therapeutic quality for rectal cancer. Methods: Multicentre retrospective cohort study in a representative sample of patients diagnosed with rectal cancer in the Institut Català d'Oncologia, a comprehensive cancer centre with three different settings. We developed a set of indicators to assess the key areas of the radiotherapy process. The clinical audit consisted of a review of a random sample of 40 clinical histories for each centre. Results: The demographic profile, histology and staging of patients were similar between centres. The MRI reports did not include the distance from tumour to mesorectal fascia (rCRM) in 38.3% of the cases. 96.7% of patients received the planned dose, and 57.4% received it at the planned time. Surgery followed neoadjuvant treatment in 96.7% of the patients. Among this group, postoperative CRM was recorded in 65.5% of the cases and was negative in 93.4% of these. With regard to the 34.5% (n = 40) of cases where no CRM value was stated, there were differences between the centres. Mean follow-up was 3.4 (SD 0.6) years, and overall survival at four years was 81.7%. Conclusions: The audit revealed a suboptimal degree of adherence to clinical practice guidelines. Significant variability between centres exists from a clinical perspective but especially with regard to organization and process.
