title: Evaluation of acute and late radiation morbidity in patients with gynaecologic malignancy using the RTOG criteria and Franco-Italian glossary.
abstract: OBJECTIVE
  The purpose of this study was to evaluate acute and late radiation morbidity in patients with gynaecologic malignancy using the RTOG criteria and Franco-Italian glossary, and to compare the usefulness and disadvantages of each system.
  
  
  METHODS
  Between February 2001 and February 2003, 107 patients with gynaecologic malignancy who received either radical or djuvant external radiotherapy +/- intracavitary brachytherapy or radiochemotherapy were enrolled in this study. The patients were evaluated before radiotherapy and weekly during radiotherapy for acute morbidity using the RTOG grading system and Franco-Italian glossary. Postradiotherapy evaluation was done one month after radiotherapy and at 3-month intervals thereafter. Median follow-up duration was 17 months. Morbidity was graded and recorded according to each scoring system.
  
  
  RESULTS
  Median age was 46 years (range 37-82). Sixty-four patients (59.8%) had endometrial cancer. Radical radiotherapy was applied to 26 patients because of inoperability and 81 patients received postoperative radiotherapy. Biologically effective doses for the bladder, rectum and vagina were 98.39, 103.54 and 121.81, respectively, for late morbidity (BED3); 70.88, 72.84 and 80.92, respectively, for acute morbidity (BED10). According to the RTOG grading system acute morbidity rate for the genitourinary and gastrointestinal systems, and skin were 52.3%, 83.2% and 63.5%, respectively. Late morbidity rate for the bladder, colon-rectum, skin and vagina were 16.8%, 20.6%, 47.7% and 51.4%, respectively. The morbidity rate for the bladder, nonspecific abdominal, hematopoietic system, uterus-vulva-vagina, skin and rectum were 35.4%, 29.9%, 5.6%, 60.8%, 40.1% and 32.7%, respectively using the Franco-Italian glossary. In patients with carcinoma of the vulva--whose treatment fields were wider--acute morbidity rate according to RTOG criteria was higher (p = 0.057); photon energy (6 Mv rather than 1.25 MV) (p = 0.01) and treatment interruption of more than eight days (p = 0.019) were correlated with decreased long-term morbidity. According to the Franco-Italian glossary morbidity rates were higher in patients who received chemotherapy (p = 0.047), both external radiotherapy and brachytherapy (p = 0.022) and treatment interruption of less than eight days (p = 0.019).
  
  
  CONCLUSIONS
  There is no common language between the RTOG grading system and Franco-Italian glossary for defining and scoring radiation morbidity. Up to date no standard and well-defined system has been developed for recording and reporting acute and late radiation morbidity in gynaecologic malignancy, but rather it depends on the subjective evaluation and experience of a radiation oncologist and subjective complaints of the patient, and sometimes on clinical findings. A standard and well-defined user friendly objective scoring system is needed to define and predict the morbidity rate more properly.
