Population-based study of the relationship of treatment and sociodemographics on quality of life for early stage breast cancer

Objective : To examine the relationship between cancer stage, surgical treatment and chemotherapy on quality of life (QOL) after breast cancer and determine if sociodemographic characteristics modify the observed relationships. Methods : A population-based sample of women with Stages 0–II breast cancer in the United States (N=1357) completed surveys including the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30), and the Breast Cancer-Specific Quality of Life Questionnaire (QLQ BR-23). Regression models calculated mean QOL scores across primary surgical treatment and chemotherapy. Clinically significant differences in QOL were defined as 10 point difference (out of 100) between groups. Results : Meaningful differences in QOL by surgical treatment were limited to body image with women receiving mastectomy with reconstruction reporting lower scores than women receiving breast conserving surgery ( p < 0.001). Chemotherapy lowered QOL scores overall across four QOL dimensions ( p values < 0.001), with a disproportionately greater impact on those with lower levels of education. Younger women reported lower QOL scores for seven of nine QOL dimensions ( p values < 0.001). Conclusions : Women should be reassured that few QOL differences exist based on surgical treatment, however, clinicians should recognize that the impact of treatment on QOL does vary by a woman’s age and educational level.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/43570/1/11136_2005_Article_0288.pd

The scored Patient-generated Subjective Global Assessment (PG-SGA) and its association with quality of life in ambulatory patients receiving radiotherapy

Objective: To evaluate the scored Patient-generated Subjective Global Assessment (PG-SGA) tool as an outcome measure in clinical nutrition practice and determine its association with quality of life (QoL)
