Exploring determinants of fear of cancer recurrence in postoperative colorectal cancer patients: a random forest model approach.

ABSTRACT:

Background

Colorectal cancer (CRC) is common in China, and many postoperative patients experience fear of cancer recurrence (FCR), which negatively affects mental health and quality of life. Predictors of FCR remain underexplored, and traditional regression may overlook complex interactions, whereas random forest (RF) modeling allows robust variable selection.

Purpose

To assess FCR prevalence and identify associated factors using a RF model.

Methods

Between November 2023 and May 2024, 314 postoperative colorectal cancer patients were enrolled at Fudan University Shanghai Cancer Center. Data were collected using the Brief Illness Perception Questionnaire (BIPQ), Cognitive Emotion Regulation Questionnaire (CERQ), Social Support Rating Scale (SSRS), and Social Constraint
