Oligometastasic breast cancer (OMBC) consists of breast cancer patient with a limited number of systemic metastases (≤ 5), all of them candidates for local ablative treatment with the intention of achieving long-term control of the metastasis and, eventually, an increase in survival The first consensus for the management of patients with oligometastatic breast cancer (OMBC) was published in 2007, establishing that a more aggressive multidisciplinary strategy is recommended in order to increase the survival while maintaining a good quality of life. The current scientific evidence is based on observational studies, mainly retrospective, systematic reviews and meta-analyses, and only a randomized nonexclusive study of oligometastatic (OM) published. All trials with Stereotactic Body Radiation Therapy (SBRT) in OM cancer have shown excellent tolerance and good local control, although first trials on Lung SBRT did not prove so excellent tolerance and had some deaths due to bronchus irradiation and secondary hemoptysis. There are multiple ongoing studies researching the benefit of SBRT in oligometastatic breast cancer. Despite the lack of impact on survival seen in the NRG BR-002 Trial, SBRT probably allows the delay of the systemic treatment until progression, and so, improves the quality of life of patients. We have to wait for the results of the ongoing and future studies for clarification of the role of local treatment in OMBC., (© 2023.

Background: The objective of the study was to review the outcome of patients with parotid cancer treated with postoperative radiotherapy at Complejo Hospitalario de Navarra in the last ten years., Materials and Methods: We retrospectively reviewed patients treated with adjuvant radiotherapy between January 2008 and December 2018. We analyzed demographic data, histopathologic findings, local control (LC) and overall survival (OS)., Results: A total of 40 patients received postoperative radiotherapy during the period mentioned. There were 22 men (55%) and 18 women (45%). Median age was 58 years (19-90). By tumor histology, the most common was squamous cell carcinoma (22.5%) followed by ex-pleomorphic adenoma (15%) and adenoid cystic carcinoma (10%). According to Surgery, 19 patients (47.5%) underwent a total parotidectomy, 20 (50%) partial parotidectomy, and 1 (2.5%) a radical parotidectomy. Twenty-one patients (51.2%) underwent cervical dissection, most of them being supraomohyoid (31.7%). Reasons for adjuvant RT were: R1 resection (35% of the patients), high grade tumors (27.5%) and 17.5% because R1 surgery and R1. Radiation was administered using IMRT in most patients to a total dose of 60 Gy in 30 fractions. The 5-year overall survival (OS) (Kaplan-Meier) was 81% (95% CI: 68.5-96.2%), and 10-years - 64%. The 5-year local control (LC) (Kaplan-Meier) was 82.4% (95% CI: 91.46-73.33%) and the 10-year LC - 72.2% (95% CI: 54.9-96%). To date, only 4 patients (10%) have died due to their parotid tumor., Conclusion: The adjuvant radiotherapy added to surgery, significantly reduces the risk of recurrence in high-risk patients with a very acceptable survival rate., Competing Interests: Conflicts of interest None declared., (© 2021 Greater Poland Cancer Centre.)

Purpose: Quality of life (QL) is a key outcome for advanced disease cancer patients. The European Organization for Research and Treatment of Cancer (EORTC) has developed the QLQ-C15-PAL questionnaire, a short version of the QLQ-C30 for palliative care. The aim of the present study is to validate the QLQ-C15-PAL for use with Spanish patients with bone metastasis., Methods: For this study, we used a consecutive sample of stage IV cancer patients with bone metastases who started radiotherapy with palliative intention. Two assessments were proposed for each patient: one on the first day of treatment and one a month after the end of the radiotherapy sessions. Psychometric evaluation of the structure, reliability, and validity was undertaken., Results: One hundred and sixteen patients completed the first questionnaire and seventy five completed the second. Multitrait scaling analysis showed that all items met the standards for convergent validity, and all except the fatigue scale met the standards for divergent validity. Cronbach's coefficient met the 0.7 alpha criterion on all scales except pain (second assessment). Most QLQ-C15-PAL areas had low-to-moderate correlations with the other areas. Significant differences appeared in the comparisons between groups with regard to: patients who died before the second assessment (six areas); patients receiving chemotherapy before starting radiotherapy in the two assessments (three and four areas, respectively); the performance status in the two assessments (nine and eight areas); and the number of RT sessions received (four). Quality of life was better in the second assessment in nine areas., Conclusion: The QLQ-C15-PAL is a reliable and valid instrument when applied to a sample of Spanish patients. These results are in line with those of other validation studies.

Summary: ABSTRACT The purpose of this study was to achieve locoregional control of locally advanced laryngeal carcinoma, survival, and organ preservation using split hyperfractionated accelerated radiation therapy and cisplatin concomitantly. This study was a phase II trial of chemoradiotherapy with split hyperfractionated accelerated radiation therapy, 1.6 Gy per fraction given twice per day to a total dose of 64 to 67.2 Gy for a total of 6 weeks with a 2-week gap, and cisplatin 20 mg/m2, days 1 to 5, in continuous perfusion, concomitantly. Seventy-three patients were treated (stage IV, 64%). At a median follow-up of 55 months for living patients, median survival was 44 months, and 5-year overall survival and disease-free survival were 42% and 39%, respectively. Toxicities included mucositis (grade III, 40%; grade IV, 28%), epithelitis (grade III, 28%). Of the 73 patients, 32 (44%) have continued with their larynx free of disease. Split hyperfractionated accelerated radiation therapy and concomitant cisplatin has been demonstrated to be an active treatment for locally advanced laryngeal carcinomas, but more active combinations of chemotherapy and radiotherapy, without increase of toxicity, are necessary to increase the rate of locoregional control, organ preservation, and survival.
