What are the side effects of prostate cancer treatment?
VTP is currently performed in an operating room, and patients are retained overnight for observation; however, in the future, VTP will likely be carried out in outpatient clinics with local anesthesia, making it a relatively inexpensive treatment. An additional advantage of VTP is that it can be repeated, while some cancer-fighting treatments cannot.

What is the most effective treatment for advanced prostate cancer?
Hormone (endocrine) therapy, known as androgen ablation or androgen suppression therapy, is the main treatment for advanced prostate cancer.
What is the newest way to treat prostate cancer?
Several newer forms of hormone therapy have been developed in recent years. Some of these may be helpful when standard forms of hormone therapy are no longer working. Some examples include abiraterone (Zytiga), enzalutamide (Xtandi), and apalutamide (Erleada), which are described in Hormone Therapy for Prostate Cancer.
Does a high PSA mean cancer has spread?
In most cases, a higher PSA level indicates a poorer prostate cancer prognosis. PSA is a protein made by prostate tissue. Men with prostate cancer often have elevated PSA levels because the cancer cells make excessive amounts of this protein.
What are the signs that prostate cancer has spread?
Prostate cancer can spread to the lymph nodes in the groin area, or to other parts of the body. The most common symptoms are swelling and pain around the area where the cancer has spread. Cancer cells can stop lymph fluid from draining away. This might lead to swelling in the legs due to fluid build up in that area.
What is the life expectancy of someone with advanced prostate cancer?
A decade ago, a man with metastatic prostate cancer would typically have a life expectancy of two to three years. Today, life expectancy for men with the same advanced disease is likely to be five to six years.
How long can you live with advanced prostate cancer?
Once prostate cancer has spread beyond the prostate, survival rates fall. For men with distant spread (metastasis) of prostate cancer, about one-third will survive for five years after diagnosis.
What is the longest someone has lived with metastatic prostate cancer?
Of the 794 evaluable patients, 77% lived < 5 years, 16% lived 5 up to 10 years, and 7% lived > or = 10 years. Factors predicting a statistical significant association with longer survival (P < 0.05) included minimal disease, better PS, no bone pain, lower Gleason score, and lower PSA level.
How effective is laser ablation for prostate cancer?
The authors present the 5-year oncologic outcomes of focal laser ablation for prostate cancer treatment at a single institution. Overall, 83% of 30 men assessed were free from disease at a median follow-up of 71 months; however, 40% of those experienced in-field recurrence and underwent salvage therapy of some type.

FDA Approves First Oral Hormone Therapy for Treating Advanced Prostate Cancer. Today, the U.S. Food and Drug Administration approved Orgovyx (relugolix) for the treatment of adult patients with advanced prostate cancer.
How quickly does prostate cancer spread?
This is because, unlike many other cancers, prostate cancer usually progresses very slowly. It can take up to 15 years for the cancer to spread from the prostate to other parts of the body (metastasis), typically the bones. In many cases, prostate cancer won't affect a man's natural life span.
How long can you live with prostate cancer that has spread?
Once prostate cancer has spread beyond the prostate, survival rates fall. For men with distant spread (metastasis) of prostate cancer, about one-third will survive for five years after diagnosis.

What is the treatment for a tumor in the vein?
There are three components to this treatment: The intravenous (IV, or in a vein) injection of a special drug called a photosensitizer. This drug travels throughout the bloodstream, including the area containing the tumor.
How to treat cancer without surgery?
Photodynamic therapy is a minimally invasive way to destroy a cancer tumor in the body without surgery or radiation. There are three components to this treatment: 1 The intravenous (IV, or in a vein) injection of a special drug called a photosensitizer. This drug travels throughout the bloodstream, including the area containing the tumor. 2 During the treatment, activating the photosensitizer by applying a light at a near-infrared wavelength carried by a fiber optic tube into the tumor. The light can penetrate a very small distance into tissue and activates the drug that is present in the blood vessels at that location. 3 When the light source “excites” the drug in the tumor’s blood vessels, it causes the release of a type of oxygen that is toxic to cancer cells. For prostate tumors, this can cause the cancer cells to die off, and the blood vessels that feed the tumor become blocked (occluded) which further contributes to the death of the cancer cells.
Can you take a VTP for prostate cancer?
TOOKAD VTP as a focal treatment for prostate cancer has the potential to destroy the tumor with very minimal risk to urinary and sexual function. Until it is approved in the U.S., interested patients must travel to Mexico or Europe for the treatment.
Can photosensitizer kill prostate cancer?
For prostate tumors, this can cause the cancer cells to die off, and the blood vessels that feed the tumor become blocked (occluded) which further contributes to the death of the cancer cells. Different types of photosensitizers exist for different types of cancer, including some skin and organ cancers. Once in the body, they don’t do anything ...
Is FLA safe for prostate cancer?
FLA requires no surgery, no radiation, and no photosensitizers circulating in the body—and it is FDA-cleared for use in the U.S. The future for photodynamic therapy to treat prostate cancer remains to be seen, but the safety and effectiveness of focal laser ablation is here and now.
How many patients with VTP go into remission?
The news release states that the study found that 49% of patients treated with VTP went into “complete remission” compared with 13.5% in the control group. It further states:
How long does it take for VTP to work?
The release states VTP “only caused short-term urinary and erectile problems which resolved within three months, and no significant side-effects remained after two years.” While it’s good that harms were mentioned, it’s a disservice to patients to downplay their impact with the word “only.”
Can a prostate MRI be used for a VTP?
We can now pinpoint prostate cancers using MRI scans and targeted biopsies, allowing a much more targeted approach to diagnosis and treatment. This means we could accurately identify men who would benefit from VTP and deliver treatment more precisely to the tumour. With such an approach we should be able to achieve a significantly higher remission rate than in the trial and send nearly all low-risk localised prostate cancers into remission. We also hope that VTP will be effective against other types of cancer – the treatment was developed for prostate cancer because of the urgent need for new therapies, but it should be translatable to other solid cancers including breast and liver cancer.
Is VTP a leap forward?
A researcher’s statement that VTP represents a “a huge leap forward for prostate cancer treatment” is overblown. Further, we don’t like that same researcher’s flawed comparison of VTP with advances in breast cancer treatment:
Does the news release accurately compare VTP with the control?
In some cases, the news release accurately compares VTP with the control, active surveillance. However, it also misleads readers by comparing VTP with aggressive treatment for higher-risk prostate cancer. For example, it states:
What does the quote "Some men prefer to delay treatment but I couldn't live with the fear of the cancer spreading
The news release contains an inflammatory quote from a patient who signed up for the trial because, he said, “Some men prefer to delay treatment, but I couldn’t live with the fear of the cancer spreading until it either couldn’t be treated or needed a treatment that would stop me living a normal life.” That’s one man’s take, certainly not representative of all men — and it exaggerates the risk of small prostate cancers.
Do men need to be on the same monitoring protocol as those on active surveillance?
Finally, the news release glosses over the fact that over 1/3 of subjects needed repeat treatment within 2 years and that men undergoing VTP appear likely to need to be on the same monitoring protocol as those on active surveillance (meaning they will need biopsies, which carry risks). VTP and prostate biopsies can cause harms.
How long does it take for a VTP to progress?
The team also reports that VTP-treated patients were three times less likely to have their cancer progress, and VTP was found to double the average time to progression from 14 months to 28 months.
What is the drug that kills cancer cells in the prostate?
The treatment involves the injection of a light-sensitive drug called WST11 – derived from bacteria found at the bottom of the ocean – into the bloodstream. Upon activation with a laser, the drug releases free radicals that destroy cancer cells in the prostate.
Can prostate cancer be identified using magnetic resonance imaging?
Prof. Emberton points out that prostate cancer can now be identified using magnetic resonance imaging and targeted biopsies, meaning that it is possible to identify men who are most likely to benefit from VTP and therefore deliver more precise therapy.
Is VTP a nonsurgical treatment?
The researchers believe that the findings of their phase III trial indicate that VTP is a promising nonsurgical approach to the treatment of localized prostate cancer. “These results are excellent news for men with early localized prostate cancer, offering a treatment that can kill cancer without removing or destroying the prostate,” notes Prof.
How many men were enrolled in the phase III trial?
For their phase III trial, Prof. Emberton and colleagues enrolled 413 men from 47 treatment sites across 10 European countries, all of whom had been diagnosed with early localized prostate cancer and were under active surveillance.
How many men in the US have prostate cancer?
Around 1 in 7 U.S. men will develop prostate cancer in their lifetime. The disease is most common in men aged 65 and older. While prostate cancer is serious, most men with the disease do not die from it. Learn more about prostate cancer. For their phase III trial, Prof. Emberton and colleagues enrolled 413 men from 47 treatment sites ...
Does VTP reduce prostate cancer?
However, Prof. Emberton and colleagues suggest that VTP could reduce the need for such treatments by combatting prostate cancer in its early stages.
How many sites were involved in the VTP trial?
The trial involved 47 treatment sites from ten different European countries, most of which were performing VTP for the first time.
Where is the VTP drug derived from?
The drug used in the procedure, WST11, is derived from bacteria at the bottom of the ocean. To survive with very little sunlight, they have evolved to convert light into energy with incredible efficiency. This property has been exploited to develop WST11, a compound that releases free radicals to kill surrounding cells when activated by laser light.
Who was the first person to be treated with VTP?
One of the first people to be treated with VTP was UCLH patient Gerald, a man in his sixties who took part in the latest trial under the care of Professor Emberton. He says:
How long does it take for a VTP to work?
By contrast, VTP only caused short-term urinary and erectile problems which resolved within three months, and no significant side-effects remained after two years.
Does prostate cancer kill cancer cells?
A new non-surgical treatment for low-risk prostate cancer can effectively kill cancer cells while preserving healthy tissue, reports a new UCL-led phase III clinical trial in 413 patients. The trial was funded by STEBA Biotech which holds the commercial license for the treatment.
Is VTP being reviewed?
The VTP treatment is currently being reviewed by the European Medicines Agency (EMA), so it is likely to be a number of years before it can be offered to patients more widely.
