Therapy Response and Survival among Patients with Gynecologic Tumors Treated with Transarterial Chemoperfusion and Transarterial Chemoembolization

Background and Objectives: This study aimed to evaluate the tumor response relating to and survival benefit of transarterial chemoperfusion (TACP) and transarterial chemoembolization (TACE) in the treatment of patients with unresectable gynecologic tumors who are intolerant of or have a suboptimal response to chemotherapy and radiotherapy. Materials and Methods: Between January 2000 and October 2023, 75 patients diagnosed with gynecologic tumors underwent 213 TACP and 154 TACE procedures. Of these, 33 patients were treated with TACP, 20 were treated with TACE, and 22 received a combination of both therapies. A retrospective evaluation of local tumor response according to Response Evaluation Criteria in Solid Tumors (RECIST) was conducted, and survival rates were determined using the Kaplan-Meier estimator. Results: Of the total 75 patients, 50 (67%) maintained a stable course of disease until the completion of therapy, 10 (13%) had a partial response, 2 (3%) had a complete response following thermal ablation, and 13 (17%) experienced progression. Furthermore, a 6% reduction in the sum of the longest diameters and an 8% reduction in tumor volume were observed. The median overall survival was 16.15 months, while the median progression-free survival was 13.19 months. Conclusions: TACP and TACE are potential treatment options for local tumor control in patients with unresectable gynecologic tumors who are intolerant of or show a poor response to chemotherapy and radiotherapy. However, further investigation and adjustment of treatment protocols are required to improve therapy response and survival outcomes.
