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).

Design:

A prospective 4 week study assessing the nutritional status and QoL of ambulatory patients receiving radiation therapy
to the head, neck, rectal or abdominal area.

Setting:

Australian radiation oncology facilities.

Subjects:

Sixty cancer patients aged 24–85 y.
Intervention: Scored PG-SGA questionnaire, subjective global assessment (SGA), QoL (EORTC QLQ-C30 version 3).

Results:

According to SGA, 65.0% (39) of subjects were well-nourished, 28.3% (17) moderately or suspected of being
malnourished and 6.7% (4) severely malnourished. PG-SGA score and global QoL were correlated (r ¼ 70.66, P <0.001) at
baseline. There was a decrease in nutritional status according to PG-SGA score (P <0.001) and SGA (P <0.001); and a decrease
in global QoL (P <0.001) after 4 weeks of radiotherapy. There was a linear trend for change in PG-SGA score (P <0.001) and
change in global QoL (P ¼0.003) between those patients who improved (5%) maintained (56.7%) or deteriorated (33.3%) in
nutritional status according to SGA. There was a correlation between change in PG-SGA score and change in QoL after 4 weeks
of radiotherapy (r¼ 70.55, P <0.001). Regression analysis determined that 26% of the variation of change in QoL was
explained by change in PG-SGA (P ¼0.001).

Conclusion:

The scored PG-SGA is a nutrition assessment tool that identifies malnutrition in ambulatory oncology patients
receiving radiotherapy and can be used to predict the magnitude of change in QoL.
