贝伐珠单抗长期维持治疗晚期非小细胞肺癌39个月的病例报告及相关文献回顾

We report an advanced stage Chinese female lung adenocarcinoma patient who was negative for epidermal growth factor receptor (EGFR), V-Ki-ras2 Kirsten rat sarcoma viral oncogene homolog (KRAS) gene mutations, also negative for chinodem microtubule-associated protein-like 4/anaplastic lymphoma kinase (EML4-ALK) gene rearrangement and treated with bevacizumab (15 mg/kg) in combination with 6 cycles of conventional doses of paclitaxel and carboplatin chemotherapy. She was then treated with maintenance bevacizumab for a total of 42 cycles, the total dose of bevacizumab is 44, 730 mg. The progression-free survival was 39 months. Our findings suggest that maintenance bevacizumab for the treatment of non-small cell lung cancer (NSCLC) is safe and its benefit for long-term survival overwhelms its side effects.
