RESUMEN
PURPOSE: Current cancer treatment options include surgical intervention, radiotherapy, and chemotherapy. The quality of the provision of each of them and their effective coordination determines the results in terms of benefit/risk. Regarding the radiation oncology treatments, there are not stabilised quality indicators to be used to perform control and continuous improvement processes for healthcare services. Therefore, the Spanish Society of Radiation Oncology has undertaken a comprehensive project to establish quality indicators for use with the information systems available in most Spanish healthcare services. METHODS: A two-round Delphi study examines consensus of several possible quality indicators (n = 28) in daily practice. These indicators were defined after a bibliographic search and the assessment by radiation oncology specialists (n = 8). They included aspects regarding treatment equipment, patient preparation, treatment, and follow-up processes and were divided in structure, process, and outcome indicators. RESULTS: After the evaluation of the defined quality indicators (n = 28) by an expert panel (38 radiation oncologist), 26 indicators achieved consensus in terms of agreement with the statement. Two quality indicators did not achieve consensus. CONCLUSIONS: There is a high degree of consensus in Spanish Radiation Oncology specialists on which indicators in routine clinical practice can best measure quality. These indicators can be used to classify services based on several parameters (patients, equipments, complexity of the techniques used, and scientific research). Furthermore, these indicators allow assess our current situation and set improvements' objectives.

Data in the literature support the existence of a state of limited metastases or oligometastases. Favorable outcomes have been observed in selected patients with such oligometastases that are treated with local ablative therapies, which include surgical extirpation, stereotactic body radiation therapy (SBRT), and radiofrequency ablation. The role of SBRT in the setting of lymph node oligometastases is still emerging but the early results for local control are promising. However, the biggest challenge is to identify patients who will benefit from treatment of their oligometastatic disease with local aggressive therapy. Patients are initially categorized based upon examination of the initial biopsy, location, stage, and previous treatments received. Appropriate patient management with SBRT requires an understanding of several clinicopathological features that help to identify several subsets of patients with more responsive tumors and a good tolerance to SBRT. In an effort to incorporate the most recent evidence, here the Spanish Society of Radiation Oncology presents guidelines for using SBRT in lymph node oligometastases.

PURPOSE: To compare the results of preoperative and postoperative radiotherapy in rectal adenocarcinoma, in terms of overall survival and disease-free survival. PATIENTS AND METHODS: From 1989 to 1993, 52 patients with clinically operable rectal cancer were retrospectively analyzed. Two groups were compared: Patients in Group I received postoperative radiotherapy and those in Group II preoperative radiotherapy. Patients with a Karfnosky index > 70%, no evidence of distant disease and no major systemic problems were included in this study. RESULTS: The overall 5-year actuarial survival was 75% in Group I and 83% in Group II. The 5-year disease-free survival was 52% in Group I compared to 86% in Group II, a statistically significant difference (p = 0.025). A reduction in all Dukes' stages was observed in the preoperative radiation group, allowing preservation of the anorectal function in an increased number of patients. CONCLUSIONS: We observed better results with preoperative radiotherapy and conclude that this treatment might be justified in rectal carcinoma.
