A case of thymic cancer effectively treated by weekly paclitaxel combined with carboplatin

: A 65-year-old woman with left chest pain, back pain, and palpitation that had persisted for 2 months was referred to our hospital. Computed tomography of her chest showed an anterior mediastinal tumor with mediastinal lymphadenopathy, left pleural effusion, and pericardial effusion. Endobronchial ultrasound-guided transbronchial needle aspiration of the subcarinal lymphadenopathy was performed. The pathological findings and other examinations such as bone scintigraphy suggested advanced thymic cancer (stage IV b according to the Masaoka classification of thymic epithelial tumors). The patient was treated with combination chemotherapy of carboplatin(area under the curve [AUC]=6, 656 mg/body, day 1) and weekly paclitaxel (70 mg/m², 100 mg/body, days 1, 8, and 15). After 4 cycles of chemotherapy, a partial response was achieved and the pericardial effusion disappeared. The patient did not experience any severe toxicity, except for grade 1 nausea, grade 2 anemia, and grade 2 alopecia. Weekly paclitaxel combined with carboplatin appears to be a useful regimen with minimal toxicity for advanced thymic cancer.
