Purpose:
This study aimed to measure symptoms of posttraumatic stress disorder (PTSD) in Chinese patients following a new diagnosis of lung cancer. Secondary aims were to explore factors at diagnosis that may predict PTSD symptoms at 6 months.
Methods:
This was a prospective longitudinal observational study that included 93 patients with newly diagnosed lung cancer. PTSD symptomology was assessed using the PTSD Checklist Civilian Version (PCL-C) and health-related quality of life (HRQoL) was assessed with the European Organisation for the Research and Treatment of Cancer questionnaire. Measures were completed at diagnosis and 6 months.
Results:
No patient had PTSD at baseline or 6 months as measured by a score of ⩾50 in the PCL-C. However, at diagnosis, 44% of patients had "mild" symptoms of PTSD. At 6 months, 64% of patients had "mild" and 8% had "moderate" PTSD symptoms. PTSD symptom scores significantly worsened over 6 months (mean difference [95% CI] = 7.2 [5.4 to 9.0]). Six months after diagnosis, higher PTSD scores were seen in people who at diagnosis were younger ( P = .003), had a lower smoking pack history ( P = .012), displayed less sedentary behavior ( P < .005), or initially had worse cancer symptoms, including fatigue ( P = .001) and poorer HRQoL ( P = .004).
Conclusions:
Mild PTSD symptoms are common in patients with lung cancer 6 months after treatment; however, a full diagnosis of PTSD is uncommon. Screening for PTSD symptoms may be considered for at-risk patients with newly diagnosed lung cancer.
