Nab-paclitaxel plus carboplatin as an effective and safe chemotherapy regimen for pulmonary carcinosarcoma with interstitial lung disease: A case report

Carcinosarcoma is a rare histological type of non-small cell carcinoma (NSCLC), and its prognosis has been reported to be worse compared with other NSCLCs. Nanoparticle albumin-bound paclitaxel (nab-PTX) + carboplatin (CBDCA) achieves a favorable response rate in patients with non-small cell lung cancer (NSCLC). We administered nab-PTX + CBDCA to a 68-year-old man with postoperative recurrent carcinosarcoma with interstitial lung disease (ILD). A partial response was evident after four cycles of chemotherapy. To the best of our knowledge, the present study is the first to report the safety and efficacy of nab-PTX + CBDCA for treating carcinosarcoma with ILD.
