ancer patients with curable/controllable disease who deteriorate without an obvious clinically detectable cause have led
researchers to investigate the relation between depression and cancer outcomes. Depression has been associated with
unfavourable cancer treatment outcomes as decreased compliance, decreased desire for life-sustaining treatment and increased
mortality. Lab studies demonstrated that neurotransmitters are capable of altering immune function whereas immune-derived
mediators regulate neuroendocrine and autonomic outflow from the brain. Host cellular defenses against cancer involve immune
mediated mechanisms that can be influenced by neurotransmitter activity. Polymorphisms of the 5-HTT gene explain why some
individuals develop psychological morbidities on exposure to stressful life events while others exposed to the same conditions
don't. This offers a screening criterion for identifying patients at risk for psychological morbidity that might be detrimental to
their treatment outcome and may be used as a prognostic indicator and as a patient selection tool for comprehensive psychiatric
care during cancer treatment.
To study the role of 5HTT gene as a prognostic indicator in cancer.
A longitudinal observational study in which cancer outcomes are compared in two independent cohorts of cancer
patients grouped by 5HTT genotype (patients with two long alleles versus those with at least one short allele).
Cox proportional hazards model showed a significant difference in progression-free survival between the long/long
genotype group and the short/short genotype group after correction for age, cancer type and stage (p=0.031). The difference
between the long/long genotype group and the short/long genotype group was not statistically significant. There was no
statistically significant difference between the groups in objective tumour response rate at six months.
