| Summary: | Breast cancer remains as the main cause of death among female worldwide. In light of its good
prediction on survival of cancer, perceived quality of life (QoL) has been increasingly
recognized as an important clinical outcome for oncology patients. This study aimed to determine
the perceived QoL as well as its determinants among breast cancer patients during treatment.
This was a cross sectional study. A total of 179 breast cancer patients in National
Cancer Institute, Putrajaya were recruited via purposive sampling. A set of interviewer-
administered questionnaire was used, including European Organization for Research and Treatment
of Cancer-Quality of Life-Core 30 (EORTC-QLQ-C30), modified Medical Outcomes Study Social
Support Survey and International Physical Activity Questionnaire-short form aimed to ascertain
the perceived QoL (primary measure), functional health and medical symptoms, social support and
physical activity level, respectively. Physical functioning was measured based on the total mean
score of 5 items in EORTC-QLQ-C30. Nutritional assessments of weight, height, mid-upper arm
circumference (MUAC), triceps skinfold thickness, handgrip strength and presence of edema were
performed using standard techniques. Biochemical data on serum albumin, hemoglobin level and
neutrophils count were retrieved from medical report as secondary data. Patients’ diet
quality were evaluated using Healthy eating index-2015. Multiple linear regression was used to
identify the factors contributing to perceived QoL.
Respondents’ mean age and monthly income were 50.49 years and RM1962.83, respectively. A
majority of the respondents was Malays (61.5%), married (68.6%), received secondary education
(48.5%) and unemployed (60.9%). Slightly more than
one-third of the respondents were diagnosed with cancer stage III, with mean duration of diagnosis at 8.77 months. The mean score of perceived QoL was 69.43, with
approximately 47% of respondents had poor perception of QoL. Among the functional domains,
respondents had the lowest score on emotional functioning. A substantial proportion of
respondents experienced fatigue (94.1%), pain (60.4%), appetite loss (45.0%), insomnia
(45.0%), financial difficulties (41.4%) and constipation (33.1%). Slightly more than one quarter of
the respondents had poor social support while 62.7% of them were physically inactive. Approximately
one in five had low corrected arm muscle area. More than 90% of the respondents had poor handgrip
strength and poor diet quality. In terms of diet quality, the scoring of whole grains, dairy, fatty
acids and refined grains were less satisfactory with scores less than half of the maximum score.
For bivariate results, MUAC and handgrip strength were positively associated with perceived QoL
while respondents with earlier cancer stage experienced poorer perception of QoL.
In conclusion, breast cancer patients perceived their QoL as average during treatment, with
emotional health was the most negatively affected. There were six factors associated
with poor perception of QoL, which included early-stage cancer, lower handgrip strength
and MUAC, better physical functioning, higher levels of fatigue and pain (R²=0.522; adjusted
R²=0.457). To promote better QoL among breast cancer patients during treatment,
appropriate strategies to improve MUAC and handgrip
strength of the breast cancer patients are highly recommended. |
