Clinical features and intervention timing in patients with pregnancy-associated non-small-cell lung cancer

There is no standard procedure available to diagnose and treat with pregnancy-associated non-small cell lung cancer (NSCLC). The present study was to investigate the clinical and molecular features, and the proper intervention timing for this population. This is a retrospective, pooled analysis. Cases from Guangdong Lung Cancer Institute and other published cases were collected and reviewed. The overall survival (OS) was analyzed according to the diagnosis timing, the treatment timing and the molecular character. The safety profile during pregnancy was also evaluated. Seventy-seven cases were collected including 11 patients from our center. The anaplastic lymphoma kinase ( ) gene rearrangement and epidermal growth factor receptor ( ) mutation rates were 47% and 32%, respectively. The OS of patients treated during pregnancy, after delivery, and those not treated differed significantly [12 months not reached (NR) 1 month; P
