Results PORT was administered with 3-dimesional conformal radiotherapy in 23 patients while 4 patients were treated with intensity-modulated radiotherapy. The median planning target volume (PTV) was 250cc (range 60-610). Median dose was 54 Gy delivered using conventional fractionation (2 Gy daily). Median follow-up was 54 months. OS at 1- and 5-years was 96.3% and 89%. One- and 5-year RFS was 100% and 83%. MFS at 1- and 5-years was 92% and 67%. Patients with stages III-IV had worst 5-yers OS and MFS compared to stages III-IV, 83 vs 100% (CI 95%: 1.16-2.06; p 0.03) and 45 vs 100% (CI 95%: 1.42- 2.8; p 0.01). WHO histologies B2-B3-0 showed worst 5-years OS and MFS compared to A-AB-B1 group, 82.6 vs 100% (CI 95%: 1.27-2.2; p 0.02) and 46.6 vs 100% (CI 95%: 1.2-2.6; p 0.02) . No acute nor late G3-4 toxicities were observed. Conclusion PORT in patients with thymic malignancies achieved good local control and a safe toxicity profile. Patients with III and IV Masaoka stage and WHO B2-B3-0 histology had significant worst OS and MFS.

1 Abderrahmane Mami Hospital, radiation oncology, Tunis, Tunisia; 2 Abderrahmane Mami Hospital, Radiation Oncology, Tunis, Tunisia Purpose or Objective The aim of this study was to assess patients’ feelings when the subject of sexuality is approached by the radiation oncologist. Materials and Methods From September 1, 2021 to October 9, 2021, we conducted a qualitative study including 30 patients followed for breast or pelvic cancer treated in the radiotherapy department of the Abderrahmane Mami Hospital in Ariana. During consultations, a sexuality assessment was carried out. The radiation oncologist collected patients’ feelings asking the following questions: have other health workers discussed the topic of sexuality? Do you think it is the role of the radiation oncologist to ask questions about your sexual life? How did you feel: surprised, joyful, against or indifferent? Results The mean age of the 30 included patients was 48 years [27 - 63]. Twenty patients were treated for breast cancer and 10 patients for pelvic cancer. Seven patients (23.3%) reported that their oncologist had already discussed the subject of sexuality (surgeon in 2 cases, medical oncologist in 1 case and radiotherapist in 4 cases). Fourteen patients (46.6%) said that they would take the initiative to bring up such a discussion if they have sexual disorders. Twenty-seven patients (90%) estimated that their radiation oncologist should initiate the subject of sexuality. Concerning patients’ feelings, two patients (6.6%) were surprised, 10 patients (33.3%) expressed their joy, 17 patients (56.6%) took a neutral position, and one patient (3.3%) expressed her displeasure. Conclusion Our study showed that only 23% of patients were previously asked about their sexuality. The approach of sexuality by the radiation oncologist was acceptable by 90% of the patients. A strong expectation to talk about it was noted in our study: one third of patients expressed their joy.
