1. Subjective Memory Complaints [5-10 years after radiotherapy]
Assessed by Cognitive Failure Questionairre:
a questionairre about failures in perception, attention, memory, and motor function.
29 items Total score Range 0-100
2. Cognitive function [5-10 years after radiotherapy]
Cognitive function per cognitive domain:
Available normative data will be used to convert the patients results on the neuropsychological tests into standardized T scores (mean, SD), adjusted for age, sex and education.
3. Hospital Anxiety and Depression Scale (HADS). [5-10 years after radiotherapy]
Hospital Anxiety and Depression Scale (HADS). The total scores range is 0-21 for both depression and anxiety scores. A higher score indicates a worse depression and anxiety.
14 items Score depression: Range 0-21 Score Anxiety: Range 0-21 Total score: Range 0-42
4. Fatigue severity [5-10 years after radiotherapy]
Fatigue severity was assessed using the Checklist Individual Strength (CIS20R), a 20-item questionnaire that takes around five to ten minutes to fill out. Each question has a statement to be scored on a 7-point Likert scale ranging between 'yes, this is true' to 'no, this is not true'. The total score is calculated as the sum of the responses to the different statements. The maximum CIS20R score is 140, with a score of 76/140 or higher indicating that the patient is at risk for prolonged absence at work. The scale is subdivided in four dimensions of fatigue being fatigue severity (8 items, max. score 56), concentration problems (5 items, max. score 35), reduced motivation (4 items, max. score 28) and activity (3 items, max. score 21).
Total score: Range 20-140
5. Speech Handicap Index (SHI) [5-10 years after radiotherapy]
Assessed by Speech Handicap Index:
a questionairre assessing self perceived speech function. 30 items A total SHI can be calculated ranging from 0-120, with higher scores indicating more speech problems and with a cutoff value of 6 being able to identify patients with speech problems in daily life.
6. Brief symptoms Inventory (BSI) [5-10 years after radiotherapy]
Assessed by Brief Symptom Inventory measure Brief Symptom Inventory (BSI) measure consists of 18 emotional distress items that are rated on a 5 point Likert scale and yield a Global Severity Index as well as Symptom Dimensions (Somatization, Depression, Anxiety.
Total score: Range 0-72
7. Fear of recurrence [5-10 years after radiotherapy]
Assessed by the Cancer Worry Scale (CWS):
self reported 8-item scale, measuring worry about the risk of cancer recurrence and its impact on daily functioning. Total score ranges from 8 to 32. Higher scores indicate higher FCR. A cutoff score of 13 vs 14 (low FCR 13 or lower; high FCR 14 or more) has been established to differentiate between those with normal FCR from those with bothersome levels of FCR. This cutoff had been validated relative to the Fear of Cancer Recurrence Inventory cutoff score, which is a validated maesure.
8. Cancer specific distress [5-10 years after radiotherapy]
Assessed by Impact of Event Scale-Revised, which is a 22-items scale and includes subscales of intrusion, sleep disturbance, hyperarousal, avoidance and numbing. Items are scored on a 5-point scale, ranging from 0 (not at all) to 4 (extremely).
9. Quality of Life [5-10 years after radiotherapy]
