BRCA1 and non-small cell lung carcinoma: As shown in Figure 3 and 4, BRCA1 mRNA expression levels were inversely correlated with sensitivity to cisplatin in malignant pleural effusions of NSCLC patients (P = 0.014, r = 0.541; Figure 3) and in ascites of gastric patients (P = 0.002, r = 0.624; Figure 4).
