Predictive Value of the Distress Thermometer as a Predictive Screening Instrument to Detect Cancer-related Cognitive Impairment in Cancer Patients

Cognitive impairment associated with chemotherapy is an important reported post-treatment side-effect among breast and other cancer survivors. As some patients report cognitive complaints before the administration of their therapy, some authors suggest an association with psychological risk factors such as distress. Distress, a multifactorial unpleasant emotional experience of a psychological (cognitive, behavioral and emotional), social and/or spiritual nature that may interfere with the ability to cope with cancer effectively, its physical symptoms and its treatment, can easily be assessed by the Distress Thermometer. In this trial we aim to determine if the Distress Thermometer, accompanied by the 38-item Problem List, could predict cancer-related cognitive impairment in patients with hematologic malignancies, and in patients with gynecological, urological, breast, lung or gastro-intestinal cancer receiving curative radiotherapy, chemotherapy, radiochemotherapy, anti-hormonal or targeted therapy.
