Recently Diagnosed or Relapsed? Stop Looking For a Miracle Cure, and Use Evidence-Based Therapies To Enhance Your Treatment and Prolong Your Remission
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.

Gut Microbiota Myeloma Patients Autologous Stem Cell Transplant
The gut microbiota of myeloma patients and autologous stem cell transplant can heavily influence each other. The challenge is to understand the influence.
I am not an oncologist. I am a long-term MM survivor who has lived with a host of long-term and late-stage side effects from my aggressive induction therapy and ASCT. My goal is to provide non-conventional therapies that can limit or even prevent short-term, long-term, and late-stage side effects from your ASCT.
It is common for conventional oncology to push the newly diagnosed MM patient to have an ASCT. I believe an ASCT is a lot of toxicity and therefore only beneficial for the NDMM patient who hasn’t responded well to their induction therapy.
My point is that, if the MM patient does choose to have an ASCT, he/she should prepare themselves as best they can.

Associations Between the Gut Microbiome and Outcomes in Autologous Stem Cell Transplantation: A Systematic Review
Abstract
Autologous stem cell transplantation (ASCT) is the standard frontline consolidation strategy in fit, eligible patients with chemosensitive multiple myeloma, and it also serves as salvage option in other haematological malignancies, such as diffuse large B cell lymphoma.
Moreover, ASCT is known to disrupt the gut microbiome (GM), and the impact on clinical outcomes has been understudied. This review aims to examine the associations between the GM and outcomes in patients undergoing ASCT.
Using the PRISMA 2020 guidelines for systematic reviews and meta-analyses, a total of 11 articles were included in this review, comprising both observational studies (cohort studies, case–control studies) and interventional trials (randomised controlled trials).
Consistent findings included a notable decrease in beneficial bacteria, including Bacteriodetes, Firmicutes and Faecalibacterium prausnitzii, which maintain gut homeostasis and modulate immune responses. Conversely, an increase in pathogenic bacteria, including Escherichia coli, Enterococcus spp. and Klebsiella spp., was observed post-transplantation.
This review includes an overview of the GM following ASCT and the techniques commonly used to assess it, and highlights gaps, thereby identifying key areas for future research, although conclusions are limited by variation in sample size and reporting inconsistencies. Understanding the GM’s role in ASCT may lead to interventions that optimise patient outcomes through therapeutic manipulation of the GM…
This review highlights multiple observed associations between GM composition and clinical outcomes in ASCT, including relationships between specific bacterial taxa, gut integrity, immune recovery, and infection risk. Although promising, the evidence remains observational, with limited mechanistic insights or demonstrated effects…
Given these observations, promoting GM diversity may be crucial for improving outcomes in post-ASCT patients. Strategies such as dietary interventions, lifestyle modifications and the use of curated probiotics or faecal microbiota transplantation (FMT) have been proposed as ways to restore a healthy microbial balance.
By enhancing GM diversity and reducing dysbiosis, it may be possible to mitigate complications associated with transplantation and improve immune function. Furthermore, augmenting immune recovery through prebiotic or postbiotic interventions following ASCT may decrease the risk of relapse…
D’Angelo et al. [45] explored the association between GM diversity and treatment response in multiple myeloma (MM) patients, linking lower diversity at engraftment with a partial response (PR) to therapy compared to complete response (CR) or very good partial response (VGPR).
The study further highlighted the role of dietary interventions, finding that a high-fibre diet increased the abundance of Blautia species, which are associated with mucosal health and immune regulation. These findings align with the protective role of SCFA-producing bacteria observed in other studies, such as Shah et al. [46] and Pianko et al. [47]…
