Surgical approach and oncologic outcomes following multidisciplinary management of retrorectal sarcomas.

BACKGROUND: Retrorectal sarcomas are rare, and limited data are available on oncologic outcomes following surgery. Our aim was to evaluate outcomes in this patient population at our institution. MATERIALS AND METHODS: All patients who underwent surgical resection of a malignant retrorectal/presacral sarcoma between 1985 and 2005 were identified. Data analyzed included demographics, histopathologic diagnosis, surgical morbidity and mortality, use of adjuvant therapy, local and distant recurrence, and survival. RESULTS: A total of 37 patients were identified (20 males) with a median age of 49 years (range, 22-81 years). The most common histopathologic diagnosis was malignant peripheral nerve sheath tumor (n = 8). Also, 22 tumors were high grade and 15 were low grade. Surgical margin status was R0 in 31 patients and R1 in 6. Adjuvant therapy was given to 26 patients. Postoperative morbidity and mortality was 57% and 3%, respectively. Median length of follow-up in 16 patients alive at last contact was 4.7 years. The 5-year survival free of local (LDFS), distant (DDFS), and local or distant recurrence (DFS) was 51, 58, and 39%, respectively. Patient survival at 2, 5, and 10 years was 75, 55, and 47%, respectively. Disease-free survival was not significantly associated with gender (P = .16), primary vs secondary (P = .94), R0 vs R1 resection (P = .26), low vs high tumor grade (P = .17), or the use of surgery with or without adjuvant therapy (P = .33). CONCLUSIONS: Retrorectal sarcomas are often high grade and locally advanced. Most tumors are resectable with free margins, and long-term survival may be possible in up to one-half of patients following an aggressive surgical approach.

Quality-of-life after total pancreatectomy: is it really that bad on long-term follow-up?

While selected pancreatic diseases may be best treated by total pancreatectomy (TP), the anticipated sequelae of pancreatic insufficiency make TP an undesirable alternative. Our aim was to determine if patients undergoing TP have a worse quality of life (QoL) than age- and gender-matched controls and poor long-term glycemic control. Ninety-nine patients undergoing TP from 1985 through 2002 were identified. The 34 survivors with no recurrent malignancy were surveyed with the Short Form-36 (SF-36), the Audit of Diabetes Dependent QoL (ADD QoL), the European Organization for Research and Treatment in Cancer Pancreas 26 (EORTC PAN 26), and our institutional questionnaire. Operative morbidity and mortality were 32% and 5%, respectively. Three late postoperative deaths (3%) were attributed to hypoglycemia. Of the 34 surviving patients, 27 (79%) agreed to participate at a mean of 7.5 years postoperatively. Seven patients had required 12 hospitalizations for poor glycemic control. Per the SF-36, two domains (role physical and general health) were decreased compared with an age- and gender-matched national population (P < .05). The ADD QoL demonstrated an overall decrease in QoL related specifically to the diabetes mellitus (P < .01), but comparison with insulin-dependent diabetics from other causes showed no significant difference in QoL. The EORTC PAN 26 instrument also showed measurable effects on QoL. Total pancreatectomy can be performed safely. QoL after TP is decreased compared with age- and gender-matched controls but not with diabetes from other causes; however, the changes are not overwhelming. TP should remain a viable option but in selected patients.
