Abstract
BACKGROUND
Desmoid tumors are neoplasms characterized by proliferation of fibroblasts without cytologic features of malignancy. Although desmoid tumors are not uncommon, pelvic desmoid tumors are rare and therapeutically challenging. We describe the surgical management of seven patients with histologically confirmed desmoid tumors arising in the pelvis.
STUDY DESIGN
All patients, six with primary and one with recurrent desmoid tumors of the female pelvis, were treated at Mayo Clinic Rochester between 1976 and 1997. The mean age of one African-American and six Caucasian patients was 29.8 years (range 17 to 59 years). No history of previous relevant pelvic trauma was identified; six patients experienced pelvic or leg pain (or both). All patients presented with isolated masses; five of seven were located left of the midline, generally involving the obturator internis or levator muscles (or both). The surgical approach was transabdominal, with a vaginal component in one patient. In addition to this retrospective review of these seven patients, literature addressing the management of desmoid tumors of the female pelvis is reviewed.
RESULTS
Extirpative surgery necessitated resection of musculoskeletal, vascular, or adjacent soft tissue structures. Mean tumor diameter was 13.9cm (range 5 to 27 cm). Although the median recorded blood loss was 1,425mL, one patient who refused blood products died secondary to surgical hemorrhage. The median followup for the remaining evaluable patients was 57 months (range 13 to 249 months). Recurrent disease developed in 3 of 6 patients at 3, 11, and 13 months after surgical resection and was successfully managed with subsequent reoperations, with or without adjuvant radiotherapy.
CONCLUSIONS
Although recent reports demonstrate selective regression of desmoid tumors with antiestrogen therapy, management of symptomatic pelvic desmoid tumors in young women may necessitate an operation. In our series, all primary and recurrent tumors were managed with resection of involved bone and other adjacent soft tissues. The role of adjunctive radiotherapy or hormonal therapy remains to be defined.
