Background: Therapeutic options in metastatic esophageal cancer (EC) are limited with unsatisfactory results. We evaluated the efficacy of regional chemotherapy (RegCTx) approach in diffuse metastatic EC using arterial infusion (AI), upper abdominal perfusion (UAP) and isolated-thoracic perfusion (ITP) in 14 patients (N = 8 adenocarcinoma (AC) and N = 6 squamous cell carcinoma (SQCC)) after failure to first-line palliative treatment. Methods: All patients had previously failed first-line palliative treatment attempt with systemic chemotherapy (sCTx). In total 51 RegCTx cycles (12 AI, 3 UAP and 36 ITP) were applied using cisplatin, Adriamycin and Mitomycin C. The outcome was evaluated using RECIST criteria with MediasStat 28.5.14 and SPSS–28.0. Results: No grade III or IV hematological complications occurred. The overall response rate was 41% partial response, 27% stable and 32% progressive disease. Median overall survival (OS) was 38 months (95%CI 10.1–65.9). The OS was better in SQCC with 51 months The RegCTx specific survival was 13 months (95%CI 2.9–23.1) in the entire cohort and 25 months in SQCC patients. Conclusion: RegCTx is a valuable safe approach and superior to the current proposed therapeutic options in metastatic EC after failure to first-line therapy. [ABSTRACT FROM AUTHOR]
