A 59-year-old woman, diagnosed with advanced rectal cancer, presented with a low-grade fever and dyspnea on exertion after the 2nd cycle of TAS-102. TAS-102 has promising efficacy in patients with metastatic colorectal cancer. A CT scan revealed mosaic patterns with bilateral ground-glass opacities. The drug lymphocyte stimulation test for TAS-102 was strongly positive and serum β-D glucan level was elevated. The clinical course was compatible with TAS-102-induced pneumonitis combined with pneumocystis pneumonia (PCP). We herein report a rare case of drug-induced pneumonitis in a patient receiving TAS-102 in combination with PCP.
一名59岁女性,被诊断为晚期直肠癌,在接受TAS - 102的第2个周期后出现低热和劳力性呼吸困难。TAS - 102在转移性结直肠癌患者中具有良好的疗效。CT扫描显示双侧磨玻璃影呈马赛克样改变。TAS - 102的药物淋巴细胞刺激试验呈强阳性,血清β - D葡聚糖水平升高。临床过程符合TAS - 102诱导的肺炎合并肺孢子菌肺炎(PCP)。我们在此报告1例接受TAS - 102联合PCP治疗的患者发生药物性肺炎的罕见病例。
