SINGAPORE—Cancer survivors in Malaysia may have impaired health-related quality of life (HRQOL) and high levels of psychological distress 1 year after diagnosis, according to research presented at the ESMO Asia 2016 Congress.*
Of all the patients studied, those with lymphoma had the lowest global health score (according to the EORTC QLQ C30 questionnaire) and the highest levels of psychological distress (anxiety and depression).
“We urgently need new ways of supporting cancer survivors and addressing wider aspects of wellbeing,” said study investigator Shridevi Subramaniam, of the Clinical Research Centre, Ministry of Health Malaysia, in Kuala Lumpur.
“Instead of just focusing on clinical outcome, doctors must focus equally on quality of life for cancer patients, especially psychologically, financially, and socially.”
Patient population
Subramaniam and her colleagues assessed HRQOL in 1376 cancer patients who had survived 12 months from diagnosis. The patients’ mean age was 52, and 64% were female.
Patients had breast cancer (n=403), lymphomas (n=349), colorectal cancer (n=160), mouth cancer (n=108), and female reproductive cancer (n=91).
Forty-one percent of patients had late-stage cancer, 30% had early stage, and 29% had hematologic cancer. Twenty-eight percent of patients had comorbidities.
Thirty-five percent of patients underwent surgery, 73% received chemotherapy, 43% received radiotherapy, and 13% received hormonal therapy.
Forty-six percent of patients were treated at public hospitals, 48% were treated at academic hospitals, and 6% were treated at private hospitals.
Nearly three-quarters of patients (73%) had no insurance, 20% had private insurance, 5% had insurance via their employers, and 4% had other insurance. Forty-one percent of patients had low income status, 30% middle income, and 20% high income.
Overall HRQOL
The patients reported their HRQOL using the EORTC QLQ C30, Hospital Anxiety and Depression Scale, and EQ-5D questionnaire.
For the entire patient cohort, EORTC QLQ-Q30 scores were as follows:
- Mean global health score—53.0
- Mean physical function score—72.6
- Mean emotional function score—63.0
- Mean fatigue score—32.3
- Mean pain score—26.5
The patients’ mean generic HRQOL index score (according to EQ-5D) was 0.7. And a majority of patients reported anxiety (83.5%, n=949) and depression (79.1%, n=899).
HRQOL by cancer type
Anxiety and depression was most common among patients with lymphoma. These patients also had the lowest global health score. Subramaniam said these findings might be explained by side effects from aggressive treatment.
Mean global health scores were 33.3 for lymphoma patients, 59.4 for female breast cancer patients, 59.6 for colorectal cancer patients, 59.8 for patients with mouth cancer, and 67.8 for patients with female reproductive cancers.
The generic HRQOL index scores were 0.69 (colorectal), 0.73 (lymphoma, breast, and mouth), and 0.80 (reproductive).
The proportion of patients with anxiety was 94% (lymphoma), 87.4% (colorectal), 80.5% (breast), 72.6% (mouth), and 51.7% (reproductive).
The proportion of patients with depression was 86.7% (lymphoma), 80.9% (colorectal), 75.8% (mouth), 74.4% (breast), and 50.5% (reproductive).
Predictors of HRQOL
Subramaniam and her colleagues found several significant predictors of HRQOL.
Older patients had decreased physical function and global health, as well as increased pain and fatigue. Married patients had increased fatigue. And patients without comorbidities had increased physical and emotional function as well as decreased fatigue.
Compared with those treated at private hospitals, patients treated at academic hospitals had decreased physical and emotional functions and increased fatigue. Subramaniam said this could be due to long wait times at academic hospitals, which lead to worsening conditions and more pain and discomfort.
Compared to patients with high income status, those from low income groups had increased global health and physical and emotional functions, as well as decreased pain and fatigue. Subramaniam said this could be due to higher expectations among patients with higher incomes.
Compared to patients with early stage cancers, patients with hematologic and late stage cancers had decreased global health and physical function, as well as increased pain and fatigue. Subramaniam said this could be attributed to side effects of treatment.
She added that treatment side effects might also explain why patients who did not receive chemotherapy had higher global health scores.
Patients who didn’t receive radiotherapy were twice as likely as those who did to report psychological distress. And Subramaniam attributed this to a loss of hope among patients who were not treated.
Patients treated in public and academic hospitals were less likely to be psychologically distressed than those treated in private centers. Subramaniam said this could be related to financial distress.
In closing, Subramaniam said this study indicates that cancer survivors in Malaysia have impaired HRQOL, and many experience psychological distress. Therefore, clinicians should focus on “supporting patients throughout their whole cancer ‘journey,’ especially in their lives after treatment.”
