Pre-Treatment Knowledge and Side-Effects Experienced during Chemotherapy for Breast Cancer in a Nigerian Tertiary Hospital.

Background: Chemotherapy is an important component of treatment for breast cancer as it improves tumour control, overall survival or disease-free survival but is associated with side effects that could affect patients' quality of life. Patients' understanding and expectation of these side effects can improve their coping abilities. Exploring these understanding and expectations before chemotherapy can reduce the burden of chemotherapy side effects and improve compliance to treatment by increasing their physical and psychological preparedness. The study aimed to assess how the knowledge of expected side effects of chemotherapy affected the level of coping with the side effects of chemotherapy.

Methodology: This study was carried out at the Radiation Oncology and the Surgical Oncology clinics of the University College hospital Ibadan Nigeria. Patients with breast cancer were randomly selected to participate in the study. Before commencement of 1st-course chemotherapy data on sociodemographic variables, clinical characteristics and patients' knowledge about chemotherapy side effects was collected using a set of questionnaires. While presenting for the second course, patients were asked if they encountered side effects and how long it took them to recover from the side effects. The data collected was analysed using the Statistical Package for the Social Sciences (SPSS) software version 21.

Result: A total of 110 women participated in the study. Most of the patients (85%) knew chemotherapy side effects (SE).Most of the respondents, (73.5%), received their information on the side effects of chemotherapy from doctors, followed by nurses (40.9%), internet (32.7%), peers (32.7%) and family members (12.7%). Currently employed and younger patients tended to have more knowledge concerning chemotherapy SE (p = 0.018). Patients who knew SE before treatment recovered faster than those who did not (p=0.01).

Conclusion: Majority of the patients were aware of the side effects of chemotherapy. Having knowledge about side effects was associated with faster recovery. Pre-Chemotherapy counselling should be done routinely for patients starting on chemotherapy.
