Evaluation of the Theoretical Teaching of Postgraduate Radiation Oncology Medical Residents in France: a Cross-Sectional Study

This study's purpose was to have residents evaluate Radiation Oncology (RO) theoretical teaching practices in France. An anonymous electronically cross-functional survey on theoretical teaching practices in the RO residents was conducted by (i) collecting data from residents in the medical faculties in France, (ii) comparing the data across practices when possible and (iii) suggesting means of improvement. A total of 103 out of 140 RO residents responded to the survey (73.5% response rate). National, inter-university, university and internships courses do not exist in 0% (0), 16.5% (17), 53.4% (55) and 40.8% (42) of residents, respectively. Residents need additional training due to the shortage of specialised postgraduate degree training (49.5% (51)), CV enhancement to obtain a post-internship position (49.5% (51)) or as part of a career plan (47.6% (49)). The topics covered in teaching to be improved were the following: basic concept 61.2% (63), advanced concept 61.2 (63) and discussion of frequent clinical cases 50.5% (52). The topics not covered in teaching to be improved were the following: the development of career (66.0% (68)), medical English (56.3% (58)), the organisation of RO speciality (49.5% (51)) and the hospital management of RO department (38.8% (40)). This is the first national assessment of theoretical teaching of RO residents in France.

[Stereotactic body radiation therapy for oligometastatic prostate cancer]

INTRODUCTION

The first line treatment of metastatic prostate cancer is medical or surgical androgen-deprivation. This treatment however has significant side effects that can affect the patients' quality of life. For oligometastatic patients, a new therapeutic approach, focusing on local treatment of metastases, is emerging.

METHODS

A systematic review of studies published on Stereotactic Body Radiation Therapy (SBRT) for oligometastatic prostate cancer was performed using results from search request on MEDLINE.

RESULTS

Treatment regimens vary from a single fraction of 20Gy (bone lesions) to ten fractions for a total dose of 64Gy (visceral metastases). Local control is 95.5 to 100% at 2 years with grade 1 and 2 toxicities around 10%, without any grade 3 side effects. These retrospective studies show the feasibility and very low toxicity of SBRT for this population of patients. The effect of SBRT on disease-free or global survival and quality of life has not been assessed. Several prospective trials (STOMP & ORIOLE) are underway.

CONCLUSION

Treating patients with up to five prostate cancer metastases is efficient and has a low toxicity. Prospective trials should identify which patients, if any, really benefit from this approach.
