The role of immune modulation and anti-inflammatory agents in the management of prostate cancer: A case report of six patients

Cancer is associated with chronic inflammation and disruption to normal immune function. As such, the ability to thrive in a chronically inflamed microenvironment is regarded as a hallmark of cancer. Therefore, targeting inflammation and/or correction of aberrant immunity has been a therapeutic aim. The aim of the present study was to describe the use of a novel immunotherapy, called IMM-101, which is a naturally occurring, heat-killed whole cell mycobacterium, used in combination with conventional treatments in patients with prostate cancer. The present study analysed and presented data from six patients diagnosed with prostate cancer, some of whom have metastatic disease. Treatment regimens included the use of IMM-101, the correction of vitamin D3 levels, and combination with other agents that have anti-inflammatory and immune-modulatory abilities, such as bromelain and low-dose naltrexone (LDN). Clinical responses were detected in the patients when IMM-101 was commenced and further improvements were seen when an anti-inflammatory agent was used in unison. Combination therapy quickly led to a reduction in prostate-specific antigen levels, and stabilisation of disease was often achieved as indicated by repeat MRI and PET scans. Few side effects of any kind were observed when using these combination treatments. In conclusion, IMM-101 treatment alongside an anti-inflammatory agent, such as bromelain and/or LDN, may be considered an active and safe drug combination, and is a regimen that should be considered for treating patients with prostate cancer.
