For sufferers with prostate most cancers, a excessive omega-3, low-omega-6 weight loss plan with fish oil for one yr led to a discount of prostate Ki-67 index, in line with knowledge from the CAPFISH-3 trial, which have been introduced on the 2025 ASCO Genitourinary Most cancers Symposium.
The Ki-67 index decreased by 15% for sufferers who acquired the specialised weight loss plan and fish oil, in contrast with a rise of 24% within the management group who have been instructed to not take fish oil.
“A excessive omega-3, low omega-6 weight loss plan with [fish oil] for one yr resulted in a major discount in prostate Ki-67 index — in contrast with the management group — a biomarker for prostate most cancers development, metastasis and dying,” first research writer and lead investigator, Dr. William J. Aronson, acknowledged within the presentation.
Aronson is a professor within the Division of Urology and chief of Urology at Olive View-UCLA Medical Middle and chief of Urologic Oncology at West Los Angeles Veterans Affairs Medical Middle.
The CAPFISH-3 trial was a single-center, randomized, open-label part 2 trial for males who have been on energetic surveillance for grade group 1 or 2 prostate most cancers.
A complete of 100 sufferers have been randomly assigned to be handled on both the intervention (50 sufferers) or the management group (50 sufferers). Of these enrolled, six on the intervention group weren’t administered the allotted intervention, and three within the management group weren’t administered allotted intervention.
Weight loss plan intervention within the trial consisted of lower than 30% of calorie consumption from fats; decreased consumption of meals with excessive ranges of omega-6 fatty acids like corn oil, fried meals, extremely processed meals and chips; elevated consumption of omega-3 wealthy meals like salmon and tuna; a lower than 4:1 ratio of omega-6 to omega-3; and a pair of.2 grams per day of eicosapentaenoic acid (EPA) plus docosahexaenoic acid (DHA) consumption through 4 oral fish oil capsules per day. Sufferers within the management group didn’t obtain fish oil.
Eligible sufferers had a prostate biopsy carried out with the Artemis image-fusion machine, adenocarcinoma of the prostate, and elected to bear energetic surveillance, in line with the research’s Medical Trial web site. Moreover, sufferers had scientific stage T2c or much less; Gleason grade 3 plus 4 or much less; a prostate-specific antigen (PSA) lower than 25; and a willingness to not devour lycopene, inexperienced tea or pomegranate juice/dietary supplements through the one-year research.
Exclusion standards embody a diagnostic prostate biopsy with just one core most cancers with lower than 5% of tissue concerned with most cancers; acquired finasteride or dutasteride through the prior yr; taken fish oil over the past three months; prior remedy for prostate most cancers; an allergy to fish; and different medical situations that exclude them from present process repeat prostate biopsy at one yr.
Within the intervention group, the median age was 64 years versus 64.5 years within the management group; most 3 plus 3 Gleason rating was 35 (70%) and 35 (70%); 3 plus 4 Gleason rating was 15 (30%) and 15 (30%); and median PSA was 5.9 and 5.6.
The first trial finish level was the change in Ki-67 index from baseline to at least one yr utilizing the Artemis machine from similar website biopsies with most cancers in contrast between each trial teams. Secondary finish factors embody pathologic options comparable to grade group and most tumor size, Decipher 22 gene classifier rating, serum prostate particular antigen, testosterone, cytokines and lipids.
The trial additionally yielded lowered ranges of triglyceride, lowered macrophage colony-stimulating issue ranges, and no change in tumor quantity, grade group, PSA and Decipher rating.
One limitation of the trial was the length of the yr, and to find out the results of those outcomes on scientific finish factors additional research comparable to part 3 and longer-term trials are wanted.
Based on trial investigators, the ratio of omega-6 to omega-3 within the American weight loss plan is 15:1, and linoleic acid constitutes 85% of polyunsaturated fats consumed within the American weight loss plan.
