In this more-than-phenomenal finding that joins mental health with oncology, research teams have brought to light an interesting possibility.
That the common antidepressants, especially SSRIs, may have anticancer potential. A recent study suggested that such easily accessible drugs may shrink tumors and activate the immune system more vigorously to attack cancer cells. This opens up an entirely new chapter in considering drug repurposing for cancer treatment, hopefully making therapy more accessible and affordable.
For over a couple of decades, the SSRIs have been the mainstay of treating depression and anxiety disorders. Now, from that background, they are making their presence felt on the arena of cancer immunotherapy. A very important breaking new development on a cancer cure may lie in an already well known pill. Shall we check the science behind this thrilling piece of news?
Antidepressants and Cancer: A Surprising Connection
Cancer research involving antidepressants has, all along, dealt largely with understanding mood changes in patients afflicted by cancer. However, a new angle is opening where in the scientists are finding that maybe these drugs don’t just help tumour-bearing persons; they might help in tumor regression itself. A recent study, as highlighted by the Financial Express, looks into the possibilities where fluoxetine, being an SSRI which doctors prescribe quite often, perhaps could cause tumor shrinkage in mouse models.
Such an SSRI therapy is said to work by reprogramming immune cells, especially T cells, to enable recognition and targeting of cancerous cells.
Serotonin and Immune Function: A Closer Look
One of the hallmarks of this discovery is the link between serotonin and cancer immunity. SSRIs mediate serotonin levels in the brain, but newly realized appeared that serotonin is of cardinal importance for immune regulation. Therefore, through controlling serotonin levels, these drugs could further enhance cytotoxicity-A capacity of the body against cancer the very basis of cancer immunotherapy with SSRIs.
Another major advantage of this approach is that we are dealing with an already available class of drugs with well-researched uses in psychiatry and that has durations of generically fine tolerability. These are all perfectly good candidates for drug repurposing toward cancer treatment.
From the Lab to Clinical Trials
Though still in infancy, the data are promising. There is a documented observation that mice treated with fluoxetine showed an outrageous reduction in tumor size and increased survival rates. Human trials will follow to investigate the degree of tumor regression by antidepressant drugs from animal models to real-life patients.
Furthermore, it may as well open the potential of SSRIs like Celexa and Prozac being used to target different tumor types, hence broadening its application for multiple cancers. Some preliminary results of Prozac shrinkage are promising enough to instill hope amongst researchers and patients.
A New Era in Oncology?
This new cancer breakthrough is just one account under the larger umbrella that depicts modern medicine repurposing old drugs for new treatments. If these early findings on animals could be proven on humans, it would mean the rise of a movement where oncologists are greatly reconsidering their outlook on therapy, especially regarding patients that might need an alternative to chemotherapy that costs far less and is completely non-toxic.
Conclusion
Psychiatry and oncology, therefore, are undergoing a change with the intersecting potential of antidepressants and cancer treatment. As antidepressants do their job countering the growth of cancer, it essentially lays down the foundation for SSRIs as cancer treatments, while also hinting at the immense potential of cancer immunotherapy based on common drugs.
There’s much hope with ongoing pre-clinical and clinical trials. The blending of antidepressant cancer studies into mainstream oncology may very well be the bridge to affordable and easy cancer treatment. Do keep track of the developments here-the answer that we have been looking for in the battle against cancer might just come from there.
