ABSTRACT
OBJECTIVE: Restrictive food avoidance behavior among Chinese cancer patients is common. Yet, to the authors' knowledge, no study has investigated factors associated with such behavior. This study attempted to validate a new measurement tool, the Cancer Patients Food Avoidance Behaviors Scale (CPFAB), that assessed cancer patients' belief regarding 5 perceived benefits of practicing food avoidance, and to test its applicability. DESIGN: Cross-sectional face-to-face interviews. SETTING: Two outpatient oncology clinics in 2 different districts of Hong Kong. PARTICIPANTS: A total of 245 patients with nasopharyngeal and colorectal cancer. MAIN OUTCOME MEASURES: Assessment of psychometric properties of the CPFAB. ANALYSIS: Principal components method with oblique (Promax) rotations was performed to investigate the factor structure of the CPFAB. RESULTS: Psychometric properties, which included test-retest intraclass correlations (meanâ¯=â¯0.72; SDâ¯=â¯0.12), Cronbach α (.88-.94), floor (0.4% to 5.7%) and ceiling (0% to 7.3%) effects, and item-subscale (0.67-0.79) and subscale-total (0.68-0.89) correlations, were satisfactory. CONCLUSIONS AND IMPLICATIONS: The CPFAB, a new instrument used to assess food avoidance, was developed and validated. It showed satisfactory psychometric properties and can be used to evaluate interventions that seek to modify food avoidance attitudes among cancer patients.

A woman with stage IIIb non-small cell lung cancer (NSCLC) developed disease progression with brain metastases during chemotherapy. Due to unusual circumstances, the patient received gefitinib alone, without the use of corticosteroid treatment or radiotherapy. There was a dramatic clinical improvement within 1 week. Follow-up magnetic resonance imaging of the brain 1 month later showed decreases in both the size and number of brain metastases. The patient remains well 9 months after initiation of gefitinib. It is proposed that gefitinib may have a role in treatment of brain metastases from NSCLC.
