Brief summary

RATIONALE: Monoclonal antibodies, such as trastuzumab, can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells and help kill them or carry tumor-killing substances to them. PURPOSE: This phase II trial is studying the side effects of trastuzumab and to see how well it works in treating older women with early-stage breast cancer.

Detailed description

OBJECTIVES: Primary * To evaluate the 3-year cumulative incidence of cardiac events in women 60 years and older with HER2-positive breast cancer who receive single agent trastuzumab (Herceptin®) in the adjuvant setting. Secondary * To evaluate the 1-year cumulative incidence of asymptomatic cardiac left ventricular dysfunction in women 60 years and older with Her2-positive breast cancer who receive single agent trastuzumab in the adjuvant setting. * To evaluate long-term cardiac toxicity (5-year cumulative incidence of cardiac events) in women 60 years and older with Her2-positive breast cancer who receive single agent trastuzumab in the adjuvant setting. * To assess the relation between physiologic markers of chronic heart failure and trastuzumab-related cardiac dysfunction in women 60 years and older with Her2-positive breast cancer who receive single agent trastuzumab. * To assess the relation between pro-inflammatory cytokines and trastuzumab-related cardiac dysfunction in women 60 years and older with Her2-positive breast cancer. * To determine the effect of this drug on the health-related quality of life and functional, cognitive, and mental status of women 60 years and older with Her2-positive breast cancer. * To determine the 5-year disease-free survival and overall survival of women 60 years and older with Her2-positive breast cancer who receive single agent trastuzumab in the adjuvant setting. OUTLINE: This is a multicenter study. Patients receive trastuzumab (Herceptin®) IV over 30-90 minutes on day 1. Treatment repeats every 3 weeks for up to 52 weeks in the absence of disease progression or unacceptable toxicity. Blood is collected every 6 weeks during treatment. Samples are assessed for plasma cardiac markers (N-terminal brain natriuretic protein and troponin-I) and pro-inflammatory cytokines (interleukin-6 and tumor necrosis factor-α). Patients complete Quality of Life and Quality of Health and Comprehensive Geriatric assessments of functional, cognitive, and mental status changes at baseline, weeks 26, and 52. After completion of study therapy, patients are followed periodically for 4 years.

Mean Change in Quality of Life From Baseline to Mid-treatmentFrom Baseline to mid-treatment (week 26)Quality of life was assessed by using the mean change in Functional Assessment of Cancer Therapy-Breast (FACTB) scoring instrument. The Functional Assessment of Cancer Therapy-Breast (FACT-B) is a 37-item instrument designed to measure five domains of HRQOL in breast cancer patients: Physical, social, emotional, and functional well-being, as well as a breast-cancer subscale (BCS). Each question response is based on a 5-point Likert-type scale. Scores range from 0-148. High scores indicate better QOL.
Mean Change in Quality of Life From Baseline to End of TreatmentFrom baseline to end-of-treatment (52 weeks)Quality of life was assessed by using the mean change in Functional Assessment of Cancer Therapy-Breast (FACTB) scoring instrument. The Functional Assessment of Cancer Therapy-Breast (FACT-B) is a 37-item instrument designed to measure five domains of HRQOL in breast cancer patients: Physical, social, emotional, and functional well-being, as well as a breast-cancer subscale (BCS). Each question response is based on a 5-point Likert-type scale. Scores range from 0-148. High scores indicate better QOL.
Mean Change in Functional StatusFrom Baseline to mid-treatment (week 26)Mean Change in ADL/IADL scores From Baseline to Mid-treatment. The functional status will be measured by a Comprehensive Geriatric Assessment comprised of two validated instruments: Katz's Activity of Daily Living (ADL) instrument and Lawton's Instrumental of Activities of Daily Living (IADL). The IADL scale contains eight items with a summary score from 0 (low function) to 8 (high function), with higher scores indicating higher function. The ADL scale contains six items with a summary score of 0 to 6, with higher scores indicating higher independence. A score of 6 indicates complete independence; a score of 4 indicates moderate impairment; 2 or less indicates severe functional impairment. The scores of both scales will be added together for a comprehensive geriatric assessment score.
Mean Change in Cognitive StatusFrom Baseline to mid-treatment (week 26)Mean Change in Mini Mental Status Exam (MMSE scores) From Baseline to Mid-treatment. The Mini-Mental Status Exam contains 11 items to gauge cognitive function. The minimum score is 0. The maximum score is 30. A score of 23 or lower is indicative of cognitive impairment. The higher the score, the better the participant's function (Scores 30-24 indicate uncertain cognitive impairment; scores 23-18 indicate mild to moderate cognitive impairment; scores 17-0 indicate severe cognitive impairment).
Mean Change in Psychosocial Status (Depression)From Baseline to mid-treatment (week 26)Mean Change in Geriatric Depression Scores From Baseline to Mid-treatment. The Geriatric Depression Scale (GDS) is a validated tool with 15 items. The minimum score is 0, and the maximum is 15. Scores of 0-4 are considered normal, depending on age, education, and complaints; 5-8 indicate mild depression; 9-11 indicate moderate depression; and 12-15 indicate severe depression.
Mean Change in Psychosocial Status (Social Support)From Baseline to mid-treatment (week 26)Mean Change in MOS social support scores From Baseline to Mid-treatment. The Medical Outcomes Study (MOS) Social Support survey tool measures multiple domains. It is a 19-item tool comprised of four subscales in one overall summary index. The subscales are Emotional/Informational Support, Tangible Support, Affectionate support, and Positive Social Interaction. The overall index score is determined by calculating the mean of all 19 items. Scores range from 19 to 95, with higher scores indicating high support availability to participants.
Mean Change in Nutritional StatusFrom Baseline to mid-treatment (week 26)Mean Change in Mini Nutrition Assessment scores From Baseline to Mid-treatment. The Mini Nutritional Screening is a scale comprised of six questions. The sum of the six questions is totaled to determine a score which is designed to assess if there is a risk of malnutrition. The highest score possible, 14, indicated no risk, and the minimum score of 0 indicates the highest risk possible. 12 points or greater is considered no risk or normal. Meanwhile, a score below 11 indicates possible malnutrition.
