Males with prostate most cancers on lively surveillance who consumed a weight-reduction plan excessive in omega-3 fatty acids and low in omega-6 fatty acids, together with fish oil dietary supplements, skilled a big lower within the Ki-67 index.
Amongst sufferers with prostate most cancers on lively surveillance, a one-year, excessive omega-3, low omega-6 fatty acid weight-reduction plan with fish oil capsules (D + FO) demonstrated a big discount in Ki-67 index, a biomarker for prostate most cancers development, metastasis and demise, based on research findings revealed within the Journal of Medical Oncology.
From baseline to 1 yr the Ki-67 index within the D + FO group decreased by roughly 15%. At baseline, the index was 1.34%, and after one yr, it dropped to 1.14%. In distinction, the Ki-67 index within the management group elevated by roughly 24% from baseline to 1 yr. At baseline, the index was 1.23%, and after one yr, it rose to 1.52%.
This resulted in a statistically vital distinction within the change of Ki-67 index between the teams; nonetheless, there was no vital distinction in secondary outcomes between the 2 teams which included grade group, tumor size, Decipher genomic rating or prostate-specific antigen.
“The Ki-67 index values from our trial will doubtlessly present helpful information for planning future potential trials evaluating weight-reduction plan and way of life intervention trials in males on [active surveillance],” wrote research authors.

Decipher genomic: prostate most cancers threat take a look at.
Prostate most cancers grade group: aggressiveness of prostate most cancers (scale of 1 to five).
Eructation: burping.
Metastasis: spreading of most cancers.
Concerning security, 4 of the 50 sufferers randomly assigned to the D + FO group have been withdrawn by the principal investigator as a consequence of unwanted side effects linked to the fish oils. One affected person skilled grade 2 (average) flatulence, constipation and bloating. One other affected person was withdrawn for grade 2 diarrhea, gastrointestinal discomfort and eructation. The final two sufferers have been withdrawn as a consequence of grade 1 (gentle) unwanted side effects — free stools in a single affected person and free stools, eructation and nausea within the different.
On this CAPFISH-3, single-center, part 2, randomized, open-label, two-arm research, a complete of 100 sufferers have been enrolled and randomized. Sufferers have been randomly assigned to both the D + FO group or management group.
“There aren’t any earlier trials within the literature evaluating serial Ki-67 index values over time in males on [active surveillance] and there aren’t any experiences on Ki-67 index values in sufferers with grade group 1 and a pair of prostate most cancers,” research authors wrote.
Sufferers within the intervention group obtained FO capsules, offered by Pharmavite LLC, containing a day by day dose of two.2 grams of omega-3 fatty acids, comprising of docosahexaenoic acid and eicosapentaenoic acid.
Moreover, sufferers within the intervention group additionally obtained month-to-month individualized counseling periods in-person, by way of telehealth or by phone from the study-registered dietician nutritionist. Counseling included lowering fats consumption to lower than 30% and reducing consumption of meals excessive in omega-6 fatty acids equivalent to fried meals, extremely processed meals, chips and baked items. As well as, sufferers have been inspired to extend omega-3 wealthy meals consumption (e.g., salmon, tuna).
Exclusion standards included the consumption of finasteride or dutasteride in the course of the earlier six months, earlier remedy for prostate most cancers and if the affected person has allergy symptoms to fish or is a vegetarian.
“On the premise of the underlying antiprostate most cancers mechanisms of a excessive omega-3, low omega-6 weight-reduction plan with FO dietary supplements, future trials are warranted evaluating this intervention in various levels of prostate most cancers,” research authors concluded.
