A Therapeutic Side Effect on Hydatid Cyst after Lung Cancer Treatment: A Case Report

Cystic echinococcus (CE) is an important health problem affecting societies living especially in rural areas. Our patient was a 64-year-old male who received PAIR treatment and albendazole treatment for CE at Haydarpaşa Numune Training and Research Hospital, Istanbul, Turkey between 2022 and 2025. The patient was first operated on for lung cancer. After treatment, the patient continues to live asymptomatically in the 36-month follow-up. We observed and followed up that the paxlitaxel and carboplatin treatments received by our patient caused regression in the CE lesions. We think that the effectiveness of this situation should be evaluated first with experimental studies.
