Biopsychosocial impact on caregivers of head and neck cancer patients undergoing radiotherapy at a tertiary care hospital

Introduction
Patients diagnosed with head and neck cancer are often subjected to an array of unprecedented challenges, which have seldom been scrutinized in other cancers, such as prolonged restrictions in their capacity to breathe, speak, and swallow, considerable deformity, and an alleviated risk of death. These predicaments have consequential repercussions on the psychological well-being of patients, and they debilitate the mental, social, and financial facet of not only the patient’s but also of the caregiver’s lives, placing them in a state of constant uncertainty while also deteriorating their physical and mental health.

Aim of the study
To assess the burden on the caregiver and their quality of life (QOL) using the Caregiver Quality of Life Index-Cancer (CQOLC) scale by comparing the salivary cortisol levels of caregivers at different intervals of the radiotherapy session.

Material and methods
The current study was a prospective cohort study conducted on 28 caregivers of patients undergoing radiotherapy, aged 15 years and more. The entire collection of saliva samples of each of the caregivers was collected on day 1, day 14, and day 21 of the radiotherapy session while simultaneously handing out the CQOLC for them to fill out. The samples were later analysed using an ELISA kit to measure the cortisol levels.

Results
On day 1 the QOL score was 1.97 ±0.28, on day 14 the QOL score was 2.53 ±0.31, and on day 21 the QOL score was 3.15 ±0.26, with a p-value of 0.0001 over the entire session. There was no statistically significant change in the salivary cortisol level. P < 0.05 is considered statistically significant.

Conclusions
The assessed quality of life portrayed a progressive decline over the calculated period, concluding that the radiotherapy sessions of the patients subjected the caregivers to distress. It was also found that the males had a noteworthy diminution in QOL compared to the females; however, there was no significant change in the cortisol level over the calculated period.
