Fluctuations in physical function: adults with non-small cell lung cancer

Area of Science:

• Oncology
• Nursing
• Rehabilitation Medicine

Background:

• Non-small cell lung cancer (NSCLC) significantly impacts patients' functional status and quality of life.
• Understanding physical activity disruptions is crucial for effective patient management and supportive care.

Purpose of the Study:

• To quantify physical activity disruptions in NSCLC patients over a 1-month period.
• To compare functional status between treated and untreated NSCLC patient cohorts.
• To identify factors associated with functional decline in NSCLC.

Main Methods:

• Utilized the Karnofsky Performance Status Index and two patient self-report measures.
• Monitored 24 NSCLC patients over 1 month, comparing treated and untreated subgroups.
• Analyzed changes in physical activities, including ambulation, fatigue, and household chores.

Main Results:

• Significant disruptions in physical activities were observed, with ambulation and fatigue being most affected.
• Prior weight loss correlated with baseline functional status; age was not a significant factor.
• Untreated patients exhibited greater physical limitations over time compared to treated patients, despite no baseline differences.

Conclusions:

• Careful monitoring of physical difficulties is essential for nurses to tailor interventions and alleviate distress.
• Nurses' vigilant assessment may prevent greater physical decline, as seen in untreated NSCLC patients.
• Chemotherapy treatment did not result in significantly greater physical dysfunction in this cohort.
