Background: To improve symptom management in cancer patients, the province of Ontario (Canada) implemented the collection of the Edmonton Symptom Assessment System (ESAS) and Patient-Reported Functional Status (PRFS) tool at cancer centre outpatient visits. ESAS measures 9 symptoms on a scale from 0 (no symptoms) to 10 (worst possible symptom); scores &gt; 4 (moderate to severe) require intervention. The PRFS tool is a version of the Eastern Cooperative Oncology Group performance status tool designed to be completed by the patient; scores range from 0 (“normal with no limitation”) to 4 (“pretty much bedridden, rarely out of bed”). Our main objective was to describe the symptom burden and functional status of breast cancer (BC) patients.Methods: This cross-sectional study included women with stage I-IV BC who completed the ESAS and the PRFS tool during outpatient clinic visits at 2 Toronto academic centres. ESAS and PRFS scores were described for 3 participant groups: women diagnosed with early-stage BC (ESBC= stages I-III) in the year prior to enrolment; women with ESBC diagnosed &gt; 1 year prior to enrolment; and women with metastatic BC. Multivariable logistic regression models were used to identify factors associated with ESAS scores &gt; 4 for each ESAS symptom. Covariates included age, comorbidity, BC subtype, disease group, previous surgery, and current systemic therapy. Results: Of 381 women, 107 (28%) were diagnosed with ESBC ≤ 1 year prior to enrolment; 171 (45%) were diagnosed with ESBC &gt; 1 year prior to enrolment; 103 (27%) had metastatic BC. Mean age was 57 (SD17) years. For ESBC, tiredness had the highest incidence of moderate to severe scores, followed by impaired well-being and anxiety (Table 1). For metastatic BC, impaired well-being had the highest incidence of moderate to severe symptoms, followed by tiredness and anxiety. More than 20% of metastatic BC patients had scores &gt; 4 for pain, drowsiness, shortness of breath and depression. Most reported PRFS scores of 0 (“Normal with no limitations”) or 1 (“Not my normal self, but able to be up and about with fairly normal activities”), but 17% of metastatic BC patients reported a PRFS of 2 (“Not feeling up to most things, but in bed or chair less than half the day”). A comorbidity score ≥1 was associated with moderate to severe depression (OR 2.0; 95%CI 1.1-3.7), lack of appetite (OR 3.1; 95%CI 1.4-6.6), shortness of breath (OR 2.6; 95%CI 1.3-5.2), tiredness (OR 2.0; 95%CI 1.2-3.3) and impaired well-being (OR 2.0; 95%CI 1.2-3.4). Metastatic BC was associated with moderate to severe scores for anxiety (OR 2.3; 95%CI 1.2-4.5), pain (OR 3.0; 95%CI 1.4-6.4) and impaired well-being (OR 2.1; 95%CI 1.1-4.0). Conclusion: A high prevalence of symptom scores &gt; 4 was found both in ESBC and metastatic BC, highlighting the need of symptom screening for all BC patients. Particular attention should be paid to patients with comorbidity scores ≥ 1, who have increased odds of presenting higher symptom scores.
