From 1980 to 1991, 29 patients underwent complex reconstruction following
extremity sarcoma resection. Soft tissue was the site of origin in 15
patients (52%) and bone was the site of origin in 14 patients (48%), with
20 sarcomas (69%) in the lower extremity. Resection consisted of the
following procedures: extended anatomical soft-tissue resections (21
patients [72%]), bone resections (18 patients [62%]), and joint resections
(14 patients [48%]). Reconstruction involved the following: myocutaneous
flaps (20 patients [69%]), joint prosthesis (eight patients [28%]), and
bone reconstruction (15 patients [52%]). There was no surgical mortality;
one patient required an amputation owing to surgical complications. The
site of the first failure was local (four [31%] of 13 patients), lung (five
patients [38%]), others (four patients [31%]). At a median follow-up of 23
months, 18 patients (62%) had no evidence of disease, 27 (93%) had no local
disease, 21 (72%) had good extremity function, three (10%) had major
disabilities, and five (17%) underwent amputations. Local control improved
when the margin of resection was larger than 10 mm. Disease-free survival
was 67% at 3 years. Overall survival was 51% at 5 years. Tumor size was an
independent predictor of overall survival. Local recurrence did not affect
overall survival.
