The PROCAINA (PROstate CAncer INdication Attitudes) Project (Part I): a survey among Italian radiation oncologists on postoperative radiotherapy in prostate cancer.
OBJECTIVE
Radiotherapy (RT) has an established role in the postoperative treatment of prostate cancer patients with extracapsular extension, positive surgical margins or a detectable post-operative prostate-specific antigen (PSA). Despite the large number of patients treated with postoperative RT, some issues about optimal technique, doses, volumes, timing and association with androgen deprivation are still subject of debate. The aim of this survey was to determine the patterns of choice of Italian radiation oncologists in two different clinical cases of postoperative prostate cancer patients.


METHODS
During the 2010 National Congress of the Italian Association of Radiation Oncology (AIRO), four clinical cases were presented to the attending radiation oncologists. Two of them were cases of postoperative prostate cancer, differing in T stage of the primary tumour according to the TNM classification, preoperative staging procedures, preoperative PSA (iPSA), Gleason score of biopsies and definitive pathological specimen after surgery and postoperative PSA. For each clinical case, the radiation oncologists were asked to: (a) give indication to new pre-treatment procedures for staging; b) give indication to postoperative treatment; (c) to define specifically, where indicated, the total dose, type of fractionation, treatment volumes, type of technique, type of image-guided setup control; (d) indicate whether adjuvant hormonal therapy should be prescribed; (e) define criteria that mostly influenced the prescription. A descriptive statistical analysis was then performed.


RESULTS
A total of 300 questionnaires were distributed amongst radiation oncologists attending the congress; 128 were completed and considered for this analysis (41%). Some important differences were shown in prescribing and performing postoperative radiotherapy, and some significant differences with international guidelines and data available from the literature were also reviewed and discussed.


CONCLUSIONS
Despite the results of clinical trials, significant differences still exist among Italian radiation oncologists in deciding postoperative treatment in prostate cancer patients. These patients probably deserve a more uniform approach based on updated, detailed and evidence-based recommendations.
