Abstract 2679

Background

In this study we aimed to examine the independent effect of baseline QoL and persistent CRT among pts with early BC.

Methods

We included data stage I-III BC pts treated with chemotherapy who were included in the CANTO prospective cohort study (NCT-01993498) from 03/2012 to 12/2014. The primary outcome was CRT defined as the presence at 3-6 months after the end of treatment, of any of the following toxicities (NCI-CTC-AE): infection, venous or arterial thrombosis, neurological G2-4, digestive G3-4 or pulmonary toxicities G3-4). Treatment deliver including chemotherapy dose reductions were also examined. The independent variable of this study was baseline Qol defined by the EORTC QLQ-C30 subscales of general global health status (GHS) (< or ≥ 70) and physical functioning PF (< or ≥ 90). The defined cutoffs correspond to the average values in the French general population. Clinical relevant adjustment covariates included stage, age, performance status (PS), body mass index (BMI), HR and HER2 status, baseline lymphopenia, albumin, creatinine clearance, alcohol consumption, and smoking status. Multivariable logistic models were performed.

Results

Among 3079 BC pts included in this analysis, 33% received neoadjuvant and 77% adjuvant treatment. Median age at diagnosis was 53 years, median BMI= 25 kg/m2, 94% of patients had a PS = 0 and 83% stage I-II disease. Pts reported on average a good GHS = 68 (±19) and PF = 90 (±14). GHS and PF were higher in women with better performance status PS = 0 vs 1+, (68 vs 60 p < 0.001) and 91 vs 78 p < 0.001) respectively. 952 (31%) BC pts developed ≥1 CRT: 23% had an infection, 7% thrombosis, 0.3% G3-4 diarrhea, nausea or vomiting, 4% G2-4 neurological and 0.2% G3-4 pulmonary toxicities. 16% had chemotherapy dose reduction. Pts with a baseline GHS <70 had 19 % higher odds of CRT vs to those with GHS≥70, OR = 1.19 [95% CI 1.02-1.41] and similarly those with a PF < 90 had a 23% higher odds of CRT when compared to those with PF ≥ 90 (OR = 1.23 [95% CI 1.03-1.49]).

Conclusions

Global and physical QoL before BC treatments are independently associated with CRT. QoL should be assessed before any treatment to identify patients at risk CRT.
