Certain types of immune cells in tumors may increase survival

A pilot study using recombinant rat proteins and conducted by researchers at the University of Otago shows that patients with colorectal cancer having certain types of immune cells in their tumors may increase their survival. Researchers at the Department of Microbiology and Immunology have found that people with more "T-regulated" immune cells in colorectal tumors are more likely to be disease-free and have a longer life span than those with fewer of these cells.

The study involved 32 patients with earl-stage (II) colorectal cancer. These patients received more than 5 years of follow-up: 13 patients showed cancer recurrence during this period; 19 patients showed no recurrence. These findings have been published in the International Journal Cancer Immunology, Immunotherapy.

By making use of a new tool to detect tumor and immune cells in immune cells infiltrates and measuring more complex immune cells, researchers investigated which type of immune response is associated with patient survival. The researchers found that although Immunoscore was superior to the current staging in assessing patient survival, the addition of "effectally Treg" immune cells made it better to survive. Kirsten Ward-Hartstonge, co-author and doctoral scholar of the study, said, " The findings suggest that it is possible to detect the immune response of patients with colorectal cancer to estimate which patients may be suffering from cancer and therefore should be given additional treatment. This information can be used to customize existing treatment programs to target people who really need them, rather than taking more blankets."

"About a quarter of patients who are currently considered ‘low risk’ will use the current staging method to potentially develop the disease again," Miss Ward-Hartstonge said. These patients usually do not receive chemotherapy or radiotherapy because the risks and costs are considered to be more beneficial.

By detecting immune cells from individual patients and "Treg" immune cells, it may be possible to more accurately identify patients with high risk and more effective treatment. Other studies have shown that New Zealand and Australia have the highest incidence and mortality rates for colorectal cancer in the world.
