the value of geriatric assessments in older patients with breast cancer

Conditions: Aging; Breast Cancer; Chemotherapeutic Toxicity; Survival

Summary: elderly cancer patients are a special group, often complicated by a variety of chronic diseases, which bring serious obstacles to surgery and adjuvant treatment. it is for these reasons that most patients with high-level evidence-based randomized controlled clinical trials will be part of these patients. exclusions ultimately lead to a lack of standards for the treatment of elderly breast cancer patients, especially the chemotherapy. investigators' purpose was to determine whether geriatric assessments are associated with completion of a chemotherapy course, grade iii/iv toxicity or survival in older adults with breast cancer in older patients. investigators want to prospectively enroll breast cancer patients with age ≥70 years. by recording the pre-treatment baseline laboratory tests and geriatric assessments, through questionnaires, including karnofsky performance status(kps), eastern cooperative oncology group(ecog), mini nutritional assessment(mna), activity of daily living(adl), instrumental activities of daily living(iadl), mini-mental state examination(mmse), geriatric depression scale(gds), g-8, vulnerable elders survey-13（ves-13） and frail, tilburg. investigators want to learn the relationship between the geriatric assessments and chemotherapy toxicity, chemotherapy completion and overall survival. establish a model for predicting chemotherapy side effects in old breast cancer patients.

elderly cancer patients are a special group, often complicated by a variety of chronic diseases, which bring serious obstacles to surgery and adjuvant treatment. it is for these reasons that most patients with high-level evidence-based randomized controlled clinical trials will be part of these patients. exclusions ultimately lead to a lack of standards for the treatment of elderly breast cancer patients, especially the chemotherapy. numerous studies have shown that older adults are undertreated. this may be, in part, due to concerns about a greater risk of treatment toxicity in older adults. investigators' purpose was to determine whether geriatric assessments are associated with completion of a grade iii/iv toxicity or survival in older adults with breast cancer in older patients. a predictive model that incorporates geriatric and oncologic correlates of vulnerability to chemotherapy toxicity in older adults could help both the healthcare provider and the patient weigh the benefits and risks of chemotherapy treatment and could serve as a platform to test interventions to decrease the risk of chemotherapy toxicity. investigators enroll the breast cancer patients ≥70y，the general data such as age, bmi, hemoglobin, white blood cells, creatinine, albumin, lactate dehydrogenase, blood pressure (diastolic blood pressure) were recorded; comorbidity scores using charlson's co-morbidity index（cci） scores; a wide variety of comprehensive assessment scales for the elderly, after searching previous research and considering the operability of the actual data collected, the kps, ecog, mna, adl, iadl, mmse, gds, g-8, vulnerable elders survey-13（ves-13） and frail, tilburg assessments were included. the treatment for these participants were decided by their own doctors. the participants who underwent chemotherapy were recorded for their chemotherapy regimen and dosage, and the side effects of chemotherapy were evaluated at the first cycle and after the end of the drug. the surgical methods, pathology after operation, radiotherapy and endocrine therapy also recorded. long-term follow-up, record the participant's recurrence and recurrence time, cause of death and time. investigators want to learn the relationship between the geriatric assessments and chemotherapy toxicity, chemotherapy completion and overall survival. establish a model for predicting chemotherapy side effects in old breast cancer patients.
