The Combination of Neoadjuvant Therapy and Surgical Resection: A Safe and Effective Treatment for Rectal Gastrointestinal Stromal Tumors. Cancer Manag Res 2021; 13:4671-4678.

Abstract
Background Rectal gastrointestinal stromal tumors (GISTs) are rare digestive tumors. The treatment methods of rectal GISTs are diverse, while no standardized treatment was recommended. The aim of this study was to report the treatment mode of rectal GISTs in our center. Methods Patients with pathologically confirmed rectal GISTs who received neoadjuvant therapy and surgical resection were retrospectively collected. Perioperative complications and long-term prognosis were evaluated. Results From January 2010 to December 2019, 36 patients were pathologically diagnosed with primary rectal GISTs. After excluding patients who were treated with surgery or imatinib alone, 21 patients received neoadjuvant therapy and surgery was enrolled. During neoadjuvant treatment, tumors shrank significantly (6.53cm to 4.68cm, p<0.001) without toxicities over grade 2. The total postoperative complication rate was 42.9% (all grade). R0 resection was achieved in 76.2% patients. Transanal resection had advantages on anus preservation and postoperative recovery. No patients died during the follow-up period, 4 patients relapsed and the relapse-free survival was 81.0%. Conclusion The combination of neoadjuvant therapy and surgical resection was a safe and effective treatment for rectal gastrointestinal stromal tumors.

Clinical outcomes of different therapeutic modalities for rectal gastrointestinal stromal tumor: Summary of 14-year clinical experience in a single center. Int J Surg 2020; 77:1-7. [PMID: 32173609 DOI: 10.1016/j.ijsu.2020.03.007] [Citation(s) in RCA: 14] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/22/2019] [Revised: 02/15/2020] [Accepted: 03/06/2020] [Indexed: 12/14/2022]
Abstract
OBJECTIVE The optimal treatment for gastrointestinal stromal tumor (GIST) of the rectum is controversial due to the extremely low incidence of the disease. The aim of the present study was to compare the clinical outcomes of different treatment modalities for rectal GIST by reviewing the 14-year experience in our center. METHOD Medical records of rectal GIST patients who received surgical treatment in our center between January 2004 to December 2017 were reviewed retrospectively. Overall survival (OS) and recurrence-free survival (RFS) were used as the observation endpoints. RESULTS Included in this study were 71 GIST patients, including 42 patients who underwent local excision (LE) and 29 patients who underwent segmental resection (SR). There were differences in tumor size (P = 0.001) and malignant risk grade (P = 0.007). The LE approach achieved a lower rate of R0 resection than SR (29/42 vs.27/29, P = 0.015) and shorter hospital stay (P = 0.004). Preoperative imatinib mesylate (IM) therapy improved the rate of sphincter-sparing surgery for patients with tumors in the very low segment of the rectum (P = 0.012) and offered better R0 resection margins (P = 0.027). Multivariate analysis showed that the resection margin status (P = 0.014), risk stratification (P = 0.001) and IM therapy (P = 0.042) were independent factors affecting RFS of rectal GIST patients but not the surgical modalities (LE vs. SR, P = 0.802). Multivariate analysis showed no significant impact of these variables on OS. CONCLUSION Selection of surgical modalities has no significant impact on the prognosis. Local excision is the preferred surgical modality for resectable rectal GIST by virtue of less injury and shorter hospital stay. IM therapy has proved to be associated with improved RFS for rectal GIST patients.
