Surgical treatment of primary solitary fibrous tumors involving the pelvic ring

Abstract

The surgical treatment of primary solitary fibrous tumors (SFT) involving the pelvic ring has not been reported previously. In this study, we aimed to evaluate the efficacy of surgical treatment for this disease. From 2009 to 2015, 13 patients underwent tumor resection at our hospital, with an average age of 49.5 years (27–68 years). Four patients underwent en bloc resection, and 9 patients underwent piecemeal resections. A Chi-square test was used to compare the postoperative recurrence rates between the en bloc resection and the piecemeal resection groups (p = 0.68), and no significant difference was found between the benign and malignant solitary fibrous tumor groups (p = 0.44). The 5-year survival rate of the patients in this study was 83.3%, and the 5-year progression-free survival rate was 63.5%. The progression-free survival rate was not significantly different between the en bloc resection and piecemeal resection groups (p = 0.97). Piecemeal resection can also achieve acceptable local control, particularly for patients with sacral tumors, as they may achieve even better postoperative function with sacral nerve preservation. Recurrence and metastasis occur relatively late in the course of this disease. Therefore, long-term follow-up is required.

Perianal Solitary Fibrous Tumor in a Rare Anatomical Presentation: A Case Report and Literature Review

“…Although SFTs were initially reported only in the visceral pleura, these tumors can occur in almost every part of the human body [ 2 ]. However, a perineal location is rare, and to our knowledge, our case is the 4 th reported in the literature.…”

“…Klemperer and Rabin first reported them in 1931 [ 1 ]; however, over the years, SFTs have been found in other extrapleural sites. SFTs have been found in the limbs, pelvic cavity, abdominal cavity, neck, and central nervous system [ 2 , 3 ]. A perianal location is rare for this type of tumor.…”

Novel technical modifications of hand‑assisted laparoscopic dissection of a large obturator mass: A case report and literature review

“…Recent studies have reported on cases of SFT located in the pelvic region (21,22). However, to the best of our knowledge, SFTs spanning the obturator fossa with involvement of obturator nerve have not been reported to date.…”

Assessment of patient experiences following total sacrectomy for primary malignant sacral tumors: A qualitative study

“…Our center is the largest sacral tumor treatment center in the country and has accumulated rich experience in sacral tumor resection. Although total en bloc sacrectomy is traditionally performed in stages using combined anterior and posterior approaches, we have explored and reported one‐stage total en bloc sacrectomy via a single posterior approach to reduce operative time, blood loss, and surgical complications …”

“…and reported one-stage total en bloc sacrectomy via a single posterior approach to reduce operative time, blood loss, and surgical complications. [4][5][6][7][10][11][12] However, total en bloc sacrectomy can impair bladder and bowel function, sexual function, and lower limb function due to nerve sacrifice (S1 and below) during surgery, thereby seriously affecting ambulation and daily living and presenting challenges for maintenance of healthy psychological and social functioning. Therefore, this patient population substantially differs from those with nonsacral bone tumors and those undergoing lower sacral tumor resection.…”
