Quality of Life and Real-time Patient Experience During Neoadjuvant Therapy: A Prospective Cohort Study.

Objective: To use a customized smartphone application to prospectively measure QOL and the real-time patient experience during neoadjuvant therapy (NT).

Background: NT is increasingly used for patients with localized gastrointestinal (GI) cancers. There is little data assessing patient experience and quality of life (QOL) during NT for GI cancers.

Methods: Patients with GI cancers receiving NT were instructed on using a customized smartphone application through which the Functional Assessment of Cancer Therapy-General (FACT-G) questionnaire, a validated measure of health-related QOL, was administered at baseline, every 30 days, and at the completion of NT. Participants also tracked their moods and symptoms and used free-text journaling functionalities in the application. Mean overall and subsection health-related QOL scores were calculated during NT.

Results: Among 104 enrolled patients, the mean age was 60.5 ± 11.5 years and 55% were males. Common cancer diagnoses were colorectal (40%), pancreatic (37%), and esophageal (15%). Mean overall FACT-G scores did not change during NT ( P = 0.987). While functional well-being scores were consistently the lowest and social well-being scores the highest, FACT subscores similarly did not change during NT (all P > 0.01). The most common symptoms reported during NT were fatigue, insomnia, and anxiety (39.3%, 34.5%, and 28.3% of patient entries, respectively). Qualitative analysis of free-text journaling entries identified anxiety, fear, and frustration as the most common themes, but also the importance of social support systems and confidence in health care providers.

Conclusions: While patient symptom burden remains high, results of this prospective cohort study suggest QOL is maintained during NT for localized GI cancers.
