Four different treatment strategies in aggressive fibromatosis: A systematic review.

BACKGROUND: The treatment approach for aggressive fibromatosis is changing. Although surgery is the mainstay in common practice, recent literature is reporting a more conservative approach. We compared the local control rate for surgery, surgery with radiotherapy, radiotherapy alone and a wait and see policy in a systematic review. METHODS: A comprehensive search of the databases PubMed/Medline, Embase and Cochrane, of the medical literature published in 1999 till March 2017 was performed by two reviewers, including articles about extra abdominal aggressive fibromatosis without the genetical variants. A total of 671 studies were assessed for eligibility, and 37 studies were included for analysis, representing 2780 patients. RESULTS: The local control rates for surgery alone, surgery and radiotherapy, radiotherapy alone and observation were 75%, 78%, 85% and 78%, respectively. For patients with recurrent disease observation had a better local control rate than surgery alone (p = 0.001). In the observation group, stabilization of the tumor was seen in median 14 (range 12-35) months. The time to local recurrence in the treatment group was median 17 (range, 11-52) months. CONCLUSION: A watchful conservative first line approach with just observation and closely monitoring, by means of physical examination and MRI, appears to be justified in a subgroup of patients without clinical symptoms and no possible health hazards if the tumor would progress.

Long-term outcome and quality of life of patients with endometrial carcinoma treated with or without pelvic radiotherapy in the post operative radiation therapy in endometrial carcinoma 1 (PORTEC-1) trial.

PURPOSE: To determine the long-term outcome and health-related quality of life (HRQL) of patients with endometrial carcinoma (EC) treated with or without pelvic radiotherapy in the Post Operative Radiation Therapy in Endometrial Carcinoma 1 (PORTEC-1) trial. PATIENTS AND METHODS: Between 1990 and 1997, 714 patients with stage IC grade 1 to 2 or IB grade 2 to 3 EC were randomly allocated to pelvic external-beam radiotherapy (EBRT) or no additional treatment (NAT). HRQL was evaluated with the Short Form 36-Item (SF-36) questionnaire; subscales from the European Organisation for Research and Treatment of Cancer (EORTC) PR25 module for bowel and bladder symptoms and the OV28 and CX24 modules for sexual symptoms; and demographic questions. Analysis was by intention-to-treat. RESULTS: Median follow-up was 13.3 years. The 15-year actuarial locoregional recurrence rates were 5.8% for EBRT versus 15.5% for NAT (P < .001), and 15-year overall survival was 52% versus 60% (P = .14). Of the 351 patients confirmed to be alive with correct address, 246 (70%) returned the questionnaire. Patients treated with EBRT reported significant (P < .01) and clinically relevant higher rates of urinary incontinence, diarrhea, and fecal leakage leading to more limitations in daily activities. Increased symptoms were reflected by the frequent use of incontinence materials after EBRT (day and night use, 42.9% v 15.2% for NAT; P < .001). Patients treated with EBRT reported lower scores on the SF-36 scales "physical functioning" (P = .004) and "role-physical" (P = .003). CONCLUSION: EBRT for endometrial cancer is associated with long-term urinary and bowel symptoms and lower physical and role-physical functioning, even 15 years after treatment. Despite its efficacy in reducing locoregional recurrence, EBRT should be avoided in patients with low- and intermediate-risk EC.
