Backround and purposeThe relevance of metastasis-directed stereotactic body radiation therapy (SBRT) remains to be demonstrated through phase III trials. Multiple SBRT procedures have been published potentially resulting in a disparity practices. Therefore, the french society urological oncolgists (GETUG) recognized need for joint guidelines order standardize practice trials carried out by group.Materials methodsAfter comprehensive litterature review, 97 recommandation statements were...

Prostate cancer (PCa) pelvic radiotherapy fields are defined by guidelines that do not consider individual variations in lymphatic drainage. We examined the feasibility of personalized sentinel lymph node (SLN)-based irradiation PCa. Among a SLN study 202 patients, we retrospectively selected 57 patients with high risk involvement. Each single clinical target volume (CTV) was individually segmented and CTVs were contoured according to Radiation Therapy Oncology Group (RTOG) guidelines....

TPS5088 Background: Following Stereotactic Body RadioTherapy (SBRT) targeting prostate cancer (PCa) oligometastasis, a tumor response assessed by PSA decrease is observed in majority of case. To increase this response, immune agents can be combined with SBRT. We hypothesize that the anti-PDL1 agent Durvalumab will enhance following SBRT oligometastatic lesions. In multicenter randomized phase II trial, we therefore propose to assess comparative efficacy or without (MEDI4736) recurrent...

We present the case of a 53-year-old woman treated with analgesic radiotherapy for multiple myeloma bone lesion forearm. After first fraction 5 Gray (Gy), she presented an acute respiratory syndrome fever few hours after treatment. The same symptoms occurred second 3 days later. patient recovered quickly thanks to intravenous hydration and suspension radiotherapy. Biological tests revealed tumor lysis syndrome. concluded that clinical could be defined as cytokine release This is time in...

Extramedullary hematopoiesis (EMH) is a rare cause of spinal cord compression defined as finding hematopoietic elements outside the physiological location in bone marrow. We report case 70-year-old man with JAK 2 positive myeloproliferative syndrome type polycythemia vera (PV), initially treated hydroxyurea. Two years after diagnosis, he presented progression biological and clinical evolution associating hyperleukocytosis hepatosplenomegaly no evidence acute myeloid leukemia. Treatment...

Background: Given the potential cardiovascular risks of androgen deprivation therapy (ADT), it is essential to identify patients who may be at an increased risk for coronary artery disease (CAD). Despite recent ESC recommendations, there no consensus on when refer a patient cardiologist further evaluation. Objective: To report new diagnoses CAD in with prostate cancer (PCa) requiring ADT underwent systematic cardio-onco evaluation assessment their status. Design, Setting, and Participants:...

Abstract Cryotherapy is an ablative therapy that can be used to treat localized prostate cancer. In case of recurrence, treatment options are not well-defined, and their outcomes unknown. We therefore collected all patients treated with radiotherapy after cryotherapy for cancer recurrence in Nantes (France) between 2012 2019. identified ten patients. After a median follow-up 5 years, two presented late grade 3 toxicities; one patient rectal hemorrhage, had hematuria. Two relapsed at 61 62...
