A Prospective Study to Evaluate the Effect of Systemic Adjuvant Therapy on the Cognitive Function of Breast Cancer Patients

December 10, 2013 updated by: National University Hospital, Singapore

The primary objective of this prospective pilot study is to examine the variation of cognitive function at various time-points in stage I-III breast cancer patients who have undergone or are undergoing adjuvant systemic therapy (chemotherapy and/or anti-hormonal therapy) and compare this to a group of healthy controls to evaluate if there is a difference. All randomized patients and their respective controls would be required to complete the computerized neuropsychological assessment CANTAB at certain time-points.These patients and controls would also be given on the same day as CANTAB testing, a set of questionnaires to evaluate subjective factors such as anxiety, depression, fatigue or menopausal symptoms which may also have an effect on cognition. Subjective assessment of cognitive function will rely on self-reporting by study participants using a validated questionnaire.The potential risks to subjects are minimal, as this is a study without any intervention regarding the medical management of patients. By participating in this study, subjects will be helping in the aim of determining if there is cognitive impairment post-therapy, and if so, how prevalent is this phenomenon, when it arises and how it changes with time. This will consequentially play an important role with regard to patient knowledge. Furthermore, if chemotherapy is shown to be associated with cognitive impairment, further studies can be carried out to determine the exact pathophysiology behind this phenomenon. This will allow for sensitive and timely detection of cognitive dysfunction in patients who have received chemotherapy and/or anti-hormonal therapy, and subsequently open the avenue for research in preventing or alleviating this phenomenon. This is crucial in improving patients' quality of life, social and occupational performance.

The investigators hypothesis is that systemic adjuvant therapy in the form of chemotherapy and/or anti-hormonal therapy given to primary breast cancer patients can cause cognitive impairment.

Primary Outcome Measures

Outcome Measure
Measure Description
Examine the variation of cognitive function at various time-points in stage I-III breast cancer patients who have undergone or are undergoing adjuvant systemic therapy
To examine the variation of cognitive function at various time-points in stage I-III breast cancer patients who have undergone or are undergoing adjuvant systemic therapy (chemotherapy and/or anti-hormonal therapy) and compare this to a group of healthy controls to evaluate if there is a difference.

Secondary Outcome Measures

Outcome Measure
Determine which cognitive domains in particular are affected
Assess certain other measures such as anxiety, depression, fatigue or menopausal symptoms which may have an impact on cognitive function using a set of validated questionnaires
Compare self-perceived cognitive deficits with objective measurements
Evaluate underlying biological pathways and susceptibility to cognitive dysfunction through blood biomarker studies, genetic polymorphisms and other mechanisms which we deem to be relevant
