progression – 2). In patients with low rate of BF in <strong>the</strong> tumor (luminal A, HER2(+)<br />

type) effect was <strong>the</strong> worst (PR – 2, stabilization – 7, progression – 4 patients in both<br />

groups). The correlation coefficient was statistically significant for BF as increased<br />

ACBFV, IR, IP, and <strong>the</strong> frequency of CR + PR to nPCT of luminal B type.<br />

Conclusions: There is a correlation between <strong>the</strong> velocity of BF and degree of<br />

destruction of tumor by cytostatics. While <strong>the</strong> rate of BF depended on <strong>the</strong> molecular<br />

type of <strong>the</strong> tumor and did not depend on <strong>the</strong> size of <strong>the</strong> primary tumor.<br />

Background: The BMI is a clinical parameter that although not perfect is often used<br />

to measure adiposity. In breast cancer <strong>the</strong>re are multiple studies indicating that<br />

overweight/obesity (O/O) is related with lower survival and increased risk of relapse.<br />

It has been also reported less likely to achieve a pathological complete response<br />

(pCR) after neoadjuvant chemo<strong>the</strong>rapy (NAC) in O/O patients.<br />

Methods: We retrospectively reviewed <strong>the</strong> records of 108 patients diagnosed with<br />

invasive locally advanced breast cancer (ILABC) who had been treated with NAC<br />

(anthracycline + taxane ± trastuzumab). The aim of our study was to review <strong>the</strong><br />

impact of BMI on <strong>the</strong> pCR and <strong>the</strong> possibility of recurrence. pCR was defined as <strong>the</strong><br />

criterion of strict pCR breast+nodes.<br />

Results: From 2004 to 2011, 108 patients received NAC. Based on <strong>the</strong>ir weight and<br />

height at baseline we divided into two groups; group 1: underweight/normal (BMI<br />
