ERBB2 and cancer: In addition, the average NLR before chemotherapy was M = 2.8 (SD = 1.3, 0.9-12.2), after Cycle 1 was M = 4.7 (SD = 5.1, 0.8-27.8), and after Cycle 2 was M = 7.5 (SD = 7.7, 1.0-31.5) (Table 1). Pre-chemotherapy NLR was negatively correlated with patient age (r = -0.19, p = 0.12) and positively correlated with BMI (r = -0.08, p = 0.30), cancer staging (r = 0.09, p = 0.30), lymphovascular invasion (r = 0.11, p = 0.25), PR negative (r = 0.08, p = 0.30), and HER2 negative (r = 0.05, p = 0.38).
