Multiple Myeloma an incurable disease, but I have spent the last 25 years in remission using a blend of conventional oncology and evidence-based nutrition, supplementation, and lifestyle therapies from peer-reviewed studies that your oncologist probably hasn't told you about.

Chemo brain prevention for myeloma patients? Meaning, take steps to prevent chemo brain before the patient undergoes chemotherapy.
The first study linked below proves the relationship between the gut microbiome and chemotherapy. In essence, the meta analysis proves that chemotherapy negatively affects the gut microbiome which then opens the cancer patient up to an increase in adverse events.
The second study linked below takes the idea of the negative influence of chemotherapy on the gut microbiome and applies it to a specific side effect- chemotherapy-induced cognitive dysfunction.
Yes, the study focuses on breast cancer but I have to believe that the issues are chemotherapy, the gut microbiome and chemo brain prevention in myeloma- not the specific type of cancer in question.
A growing number of studies document the importance of therapies before undergoing chemotherapy as a therapy to prevent or reduce the risk of a host of side effects.
Can therapy before chemo prevent:
I am a long-term MM survivor who has struggled with my own chemo brain. My brain function is much better bow (dx in early ’94) but I sure wish I knew about the impact that my chemotherapy would have on my gut microbiome and what I could do about it.
I have to also put in a plug for nutrition, nutritional supplementation and lifestyle therapies shown to reduce or even prevent chemo brain. Again, I wish I knew then what I know now.

“Increasing evidence suggests that the gut microbiome is associated with both cancer chemotherapy (CTX) outcomes and adverse events (AEs). This review examines the relationship between the gut microbiome and CTX as well as the impact of CTX on the gut microbiome. A literature search was conducted in electronic databases Medline, PubMed and ScienceDirect, with searches for “cancer” and “chemotherapy” and “microbiome/microbiota”…
The significance of the current review is that we not only assessed literature examining the relationship between the gut microbiome and CTX outcomes and AEs, but also the impact of CTX on the gut microbiome during treatment.
Previous reviews examined the association between the gut microbiome and cancer survivors using limited clinical trials and attempted to elucidate the mechanisms of pathogenesis of cancer with preclinical studies (40, 41).
Of seventeen studies reviewed, we found that three studies assessed the relationship between the gut microbiome and CTX outcomes (respondent vs non respondent, PFS, OS and weight gain) with faecal samples collected prior to CTX (23–25), whereas four other studies assessed the relationship between the gut microbiome and CTX outcomes (diarrhea, FCR, low dosage vs conventional dosage, surgery vs surgery plus CTX) with faecal samples collected either after CTX or in patients with a history of CTX (36) (37–39).
In addition to evaluating these relationships, in ten other prospective studies, faecal samples were collected multiple times during CTX, and examined the impact of CTX on the gut microbiome which provided valuable insight into the importance of the gut microbiome in cancer survivors (26–35).
The findings of the current review regarding the association between the gut microbiome and CTX-related AEs and treatment outcomes are consistent with previous reviews (19, 40, 41)..”
“Highlights
Chemotherapy is notorious for causing behavioral side effects (e.g., cognitive decline). Notably, the gut microbiome has recently been reported to communicate with the brain to affect behavior, including cognition.
Thus, the aim of this clinical longitudinal observational study was to determine whether chemotherapy-induced disruption of the gut microbial community structure relates to cognitive decline and circulating inflammatory signals.
were collected from 77 patients with breast cancer before, during, and after chemotherapy.
Chemotherapy altered the gut microbiome community structure and increased circulating TNF-α.
Both the chemotherapy-induced changes in microbial relative abundance and decreased microbial diversity were related to elevated circulating pro-inflammatory cytokines TNF-α and IL-6.
Participants reported subjective cognitive decline during chemotherapy, which was not related to changes in the gut microbiome or inflammatory markers. In contrast, a decrease in overall objective cognition was related to a decrease in microbial diversity, independent of circulating cytokines.
Stratification of subjects, via a reliable change index based on 4 objective cognitive tests, identified objective cognitive decline in 35% of the subjects.
Based on a differential microbial abundance analysis, those characterized by cognitive decline had unique taxonomic shifts
over chemotherapy treatment compared to those without cognitive decline. Taken together, gut microbiome change was associated with cognitive decline during chemotherapy, independent of chemotherapy-induced inflammation.
These results suggest that microbiome-related strategies may be useful for predicting and preventing behavioral side effects of chemotherapy…”
