What You Need to Know Before You Apply

What is the purpose of this trial?

This is a prospective study to determine if the use of curcumin randomized against placebo will reduce cancer progression in patients with prostate cancer undergoing active surveillance.

Will I have to stop taking my current medications?

The trial does not specify if you need to stop all current medications, but you cannot participate if you are taking certain medications like 5α-reductase inhibitors, anabolic steroids, or drugs with antiandrogenic properties. If you are taking Curcumin, you must be willing to stop.

Is curcumin safe for human use?

Curcumin, a compound found in turmeric, is generally considered safe for human use and is approved as Generally Regarded as Safe by the US FDA. However, its clinical success is limited due to poor water solubility and rapid metabolism. ^{1 2 3 4 5}

How is curcumin different from other prostate cancer treatments?

Curcumin, a natural compound found in turmeric, is unique because it can inhibit growth and promote cell death in prostate cancer cells by affecting specific signaling pathways, such as NF-κB and epidermal growth factor receptor (EGF-R). Unlike traditional hormone therapies or surgeries, curcumin offers a natural alternative with potential chemopreventive properties. ^{3 5 6 7 8}

What evidence supports the effectiveness of the treatment Curcumin for prostate cancer?

Research shows that curcumin, a natural compound found in turmeric, can inhibit the growth of prostate cancer cells and induce cell death (apoptosis) in both laboratory and animal studies. It has been found to enhance the effects of other treatments, like TRAIL, in making cancer cells more susceptible to treatment. ^{5 6 7 9 10}

Published Research Related to This Trial

Five out of six curcumin analogues (A(2)-A(6)) were found to be more effective than curcumin itself in inhibiting the growth of PC-3 human prostate cancer cells, suggesting enhanced therapeutic potential.

These analogues also significantly increased apoptosis (cell death) in PC-3 cells and more effectively inhibited NF-κB activity, indicating a possible mechanism for their improved efficacy in cancer treatment.

The combination of curcumin and dutasteride significantly suppressed the proliferation of LNCaP prostate cancer cells and induced apoptosis, suggesting a potential therapeutic strategy for prostate cancer treatment.

This combination treatment also reduced levels of testosterone and dihydrotestosterone in the cancer cells, indicating it may effectively interfere with androgen activity within tumors.

Curcumin, a compound found in turmeric, significantly enhances the effectiveness of TRAIL in inducing cell death in androgen-sensitive prostate cancer cells (LNCaP), suggesting a potential combination therapy for improved treatment outcomes.

The combination of curcumin and TRAIL activates both the extrinsic and intrinsic pathways of apoptosis, leading to increased cancer cell death, which highlights curcumin's role in sensitizing prostate cancer cells for TRAIL-mediated immunotherapy.

Curcumin, when administered in a synthetic diet at 2% for 6 weeks, significantly inhibited the growth of androgen-dependent prostate cancer cells (LNCaP) in nude mice, demonstrating its potential as an anti-cancer agent.

The study showed that curcumin decreased cell proliferation and increased apoptosis in tumor cells, while also reducing microvessel density, indicating its effectiveness in targeting cancer growth and progression.

Curcumin significantly inhibited the growth of TRAIL-resistant LNCaP prostate cancer xenografts in mice by inducing apoptosis and reducing cell proliferation, suggesting its potential as a therapeutic agent.

The study found that curcumin enhances the effectiveness of TRAIL by upregulating apoptosis-related genes and downregulating pro-survival factors, indicating a promising strategy for overcoming TRAIL resistance in prostate cancer treatment.

Curcumin, a compound found in turmeric, effectively inhibits the epidermal growth factor receptor (EGF-R) signaling in prostate cancer cells, which could help prevent cancer progression.

The study demonstrated that curcumin reduces EGF-R protein levels, inhibits its tyrosine kinase activity, and blocks its activation by ligands, suggesting it may be a promising preventive therapy for both androgen-dependent and androgen-independent prostate cancer.
