Researchers found that the type of chemo used did seem to make a difference in the recovery of patients’ immune systems.įor instance, lymphocyte levels in patients treated with certain anthracycline-based regimens (in this case, epirubicin and cyclophosphamide) followed by the taxane docetaxel (also known as taxotere) “remained significantly depressed,” measuring at 64 percent of pre-chemo levels.ĭr. They still have 2,000, plenty of CD4 cells for an appropriate immune response.” Other chemos, other cancers? “Let’s say somebody has 4,000 CD4 cells and it’s a 50 percent reduction. “They’re decreased, but the question is, are they decreased enough to affect clinical risk for infection?” he said. He also noted that the decreased immune function observed by researchers might not make that much of a difference to breast cancer patients’ health. With solid tumor malignancies like breast cancer, this study suggests there are potential similarities to a lesser degree.”īut Pergam was quick to point out that this was a preliminary study, that different chemotherapies have different effects on the immune system and that the therapies used during the study period, June 2011 to January 2012, might be different from therapies used now. It’s really well documented that they have a delayed immune recovery after that process. “Generally, the risk we see is in our bone marrow transplant patients. “I think many of us who look at infections do see that there are late infections that occur in patients and we don’t always understand why they occur,” he said. Steve Pergam, an infectious disease researcher at Fred Hutchinson Cancer Research Center and director of infection control at Seattle Cancer Care Alliance, said the study results were “not totally surprising.” In smokers, B cell recovery “was substantially and significantly impaired,” the researchers wrote, reaching only 51 percent of pre-chemo levels after 9 months.ĭr. After nine months, B cells (important for creating antibodies) and CD4 T cells (also known as helper T cells) had only “partial recovery,” reaching only 69 percent and 60 percent of pre-chemo levels respectively, potentially leaving patients vulnerable. When it came to certain types of NK, T and B cells, however, the researchers found chemo had a long-term effect. Nine months later, most of the immune cells were up and running at pre-chemo levels. Predictably, the level of lymphocytes, which included various types of NK (or natural killer cells), T cells and B cells, dropped significantly after chemo, but the impact was short-term. Researchers looked at the immune systems of 88 breast cancer patients, measuring their levels of lymphocytes – white blood cells that work together to fight viral and bacterial infections – before and up to nine months after receiving chemotherapy. “We were surprised that the impact of chemotherapy is so long-lived." “This study has demonstrated that the adaptive immune system is altered following chemotherapy for at least nine months post-therapy,” the authors wrote in their study, published Tuesday in the journal Breast Cancer Research. The small, observational study, conducted at the U.K.’s University of Leeds and Leeds Teaching Hospitals NHS Trust, also demonstrated that smoking exacerbates this effect. Now, new research suggests that the effects of chemotherapy can compromise part of the immune system for up to nine months after treatment, leaving patients vulnerable to infections – at least when it comes to early-stage breast cancer patients who’ve been treated with a certain type of chemotherapy. Most cancer patients know that chemotherapy weakens their immune systems, putting them at risk for viral and bacterial infections.Ī month or two after chemo ends, however, most people assume their immune system has returned to normal.
