Abstract
Background/aim: Thymic carcinoma is a rare cancer with poor prognosis in unresectable cases. Treatment efficacy of carboplatin+paclitaxel (CP), lenvatinib, S-1, and sunitinib remains uncertain, with some patients experiencing increased post-treatment liver metastasis.
Patients and methods: We performed a retrospective analysis of patients with metastatic thymic carcinoma who received chemotherapy between 2006 and 2023 at the National Cancer Center Hospital. We evaluated the clinical outcomes [progression-free survival (PFS), objective response rate (ORR), disease control rate (DCR), liver metastasis response rate (LMRR), and liver metastasis control rate (LMCR)] of CP, lenvatinib, S-1, and sunitinib.
Results: A total of 178 patients were evaluated, with 78.1% having stage IV disease. Most patients had squamous cell carcinoma (85.4%), and 39 patients had liver metastases (21.9%). The most frequently administered treatments as 1st-, 2nd-, and 3rd- line were CP (85.5%), S-1 (58.3%), and sunitinib (28.4%). The median PFS was 6.8, 9.4, 4.5, and 3.4 months in CP, lenvatinib, S-1, and sunitinib. CP showed an ORR of 41.6% and LMRR of 40.9%. The reverse response, in which only liver metastasis increased despite shrinkage of other lesions, was observed in lenvatinib (20%), S-1 (3.4%), and sunitinib (8.3%).
Conclusion: CP and lenvatinib provided effective outcomes in metastatic thymic carcinoma, aligning with previous findings. S-1 and sunitinib also show clinical activity but with variable responses in liver metastases. These results highlight the importance of tailored treatment strategies, particularly for patients with liver involvement.
期刊介绍:
ANTICANCER RESEARCH is an independent international peer-reviewed journal devoted to the rapid publication of high quality original articles and reviews on all aspects of experimental and clinical oncology. Prompt evaluation of all submitted articles in confidence and rapid publication within 1-2 months of acceptance are guaranteed.
ANTICANCER RESEARCH was established in 1981 and is published monthly (bimonthly until the end of 2008). Each annual volume contains twelve issues and index. Each issue may be divided into three parts (A: Reviews, B: Experimental studies, and C: Clinical and Epidemiological studies).
Special issues, presenting the proceedings of meetings or groups of papers on topics of significant progress, will also be included in each volume. There is no limitation to the number of pages per issue.
