    Introduction: Breast cancer is the most common tumor in women and represents the leading cause of cancer death. Radiation therapy plays a key-role in the treatment of all breast cancer stages. Therefore, the adoption of evidence-based treatments is warranted, to ensure equity of access and standardization of care in clinical practice.Method: This national document on the highest evidence-based available data was developed and endorsed by the Italian Association of Radiation and Clinical Oncology (AIRO) Breast Cancer Group.We analyzed literature data regarding breast radiation therapy, using the SIGN (Scottish Intercollegiate Guidelines Network) methodology (www.sign.ac.uk). Updated findings from the literature were examined, including the highest levels of evidence (meta-analyses, randomized trials, and international guidelines) with a significant impact on clinical practice. The document deals with the role of radiation therapy in the treatment of primary breast cancer, local relapse, and metastatic disease, with focus on diagnosis, staging, local and systemic therapies, and follow up. Information is given on indications, techniques, total doses, and fractionations.Results: An extensive literature review from 2013 to 2021 was performed. The work was organized according to a general index of different topics and most chapters included individual questions and, when possible, synoptic and summary tables. Indications for radiation therapy in breast cancer were examined and integrated with other oncological treatments. A total of 50 questions were analyzed and answered.Four large areas of interest were investigated: (1) general strategy (multidisciplinary approach, contraindications, preliminary assessments, staging and management of patients with electronic devices); (2) systemic therapy (primary, adjuvant, in metastatic setting); (3) clinical aspects (invasive, non-invasive and micro-invasive carcinoma; particular situations such as young and elderly patients, breast cancer in males and cancer during pregnancy; follow up with possible acute and late toxicities; loco-regional relapse and metastatic disease); (4) technical aspects (radiation after conservative surgery or mastectomy, indications for boost, lymph node radiotherapy and partial breast irradiation).Appendixes about tumor bed boost and breast and lymph nodes contouring were implemented, including a dedicated web application. The scientific work was reviewed and validated by an expert group of breast cancer key-opinion leaders.Conclusions: Optimal breast cancer management requires a multidisciplinary approach sharing therapeutic strategies with the other involved specialists and the patient, within a coordinated and dedicated clinical path. In recent years, the high-level quality radiation therapy has shown a significant impact on local control and survival of breast cancer patients. Therefore, it is necessary to offer and guarantee accurate treatments according to the best standards of evidence-based medicine

    In breast cancer, the use of a boost to the tumor bed can improve local control. The aim of this research is to evaluate the safety and efficacy of the boost with intra-operative electron radiotherapy (IOERT) in patients with early-stage breast cancer undergoing conservative surgery and postoperative whole breast irradiation (WBI). The present retrospective multicenter large data were collected between January 2011 and March 2018 in 8 Italian Radiation Oncology Departments. Acute and late toxicity, objective (obj) and subjective (subj) cosmetic outcomes, in-field local control (LC), out-field LC, disease-free survival (DFS) and overall survival (OS) were evaluated. Overall, 797 patients were enrolled. IOERT-boost was performed in all patients during surgery, followed by WBI. Acute toxicity (≥G2) occurred in 179 patients (22.46%); one patient developed surgical wound infection (G3). No patients reported late toxicity ≥ G2. Obj-cosmetic result was excellent in 45%, good in 35%, fair in 20% and poor in 0% of cases. Subj-cosmetic result was excellent in 10%, good in 20%, fair in 69% and poor in 0.3% of cases. Median follow-up was 57 months (range 12–109 months). At 5 years, in-field LC was 99.2% (95% CI: 98–99.7); out-field LC 98.9% (95% CI: 97.4–99.6); DFS 96.2% (95% CI: 94.2–97.6); OS 98.6% (95% CI: 97.2–99.3). In conclusion, IOERT-boost appears to be safe, providing excellent local control for early-stage breast cancer. The safety and long-term efficacy should encourage use of this treatment, with the potential to reduce local recurrence

    Adjuvant chemoradiotherapy in gastric cancer: A pooled analysis of the AIRO Gastrointestinal Group experience

    Given the poor compliance with adjuvant chemoradiotherapy (CRT) in gastric cancer reported in previous studies, a survey was conducted among 18 Italian institutions within the AIRO Gastrointestinal Group to investigate current treatment modalities, toxicities, and compliance with adjuvant CRT. PATIENTS AND METHODS: Data from 348 patients operated on for gastric cancer were collected retrospectively from September 2000 to June 2008 and analyzed. The adjuvant treatments included CRT according to center guidelines. In multivariate analysis, acute hematological, gastrointestinal, and renal toxicity (according to the RTOG Acute Radiation Morbidity Scoring Criteria) and compliance with treatment were studied, as well as risk factors for local control, metastasis-free survival, disease-free survival, and overall survival. RESULTS: Compliance with treatment was excellent: 95.7% of patients completed CRT. During CRT, acute G3-G4 ­hematological toxicity was 3.7% and acute G3-G4 gastrointestinal toxicity 4%. 78.4% of patients completed chemotherapy (CT), either before or after CRT. During CT acute G3-G4 hematological toxicity was 5.4% and acute G3-G4 gastrointestinal toxicity 6%. Overall, 74.1% of patients completed the prescribed treatment (CRT and CT). Doses greater than 4500 cGy did not compensate for more aggressive disease. The 5-year overall survival was 51%. CONCLUSIONS: The adjuvant treatment of gastric cancer within the AIRO group was diverse, but radiotherapy treatment was homogeneous (in terms of technique) and well tolerated. Toxicity was low and compliance with treatment was good during CRT; these results may be due to the radiotherapy technique applied. This survey could be used as a benchmark for further studies.
