BRCA1 and non-small cell lung carcinoma: On the opposite site of its prediction value for cisplatin sensitivity, BRCA1 mRNA expression levels in malignant effusions were positively correlated with sensitivity to docetaxel, in which patients with higher BRCA1 mRNA expression levels had a higher sensitivity to docetaxel compared with those with lower expression levels (NSCLC: P = 0.008, r = -0.573, Figure 5; gastric: P = 0.032, r = -0.468; Figure 6).
