High-intensity focused ultrasound: Prostate cancer treatment with potential further applications. High-frequency sound waves attack a tumor.

SDT has been developed as a complementary or alternative therapy to PDT.

Men who undergo prostatectomy may experience “dry orgasm” with no emission, as the seminal vesicles that create a large amount of the fluid of semen are removed during a radical prostatectomy.
However, sperm remain produced in the seminiferous tubules within the testes.

tissues absorb , they look white, black, or gray in the resulting pictures.
By increasing the intensity of the sound waves and focusing them on a single point, HIFU sends a great deal of energy in to the tissue, in cases like this, the prostate .

One trial involved 118 patients with a biopsy-proven local recurrence no evidence of metastases after radiation therapy.
The five-year actuarial progression-free survival rate was 78%, 49.5%, and 14% for low-, intermediate-, and high-risk patients, respectively.
Only one study, which included just four patients, has demonstrated the feasibility of treating recurrent prostate cancer carrying out a radical prostatectomy with HIFU, depending on where the cancer recurs.
In a multicenter trial of cryotherapy in 175 patients, 78% of these who were regarded as at low risk for disease progression had a PSA of less than 0.4 ng/ml after twelve months.
Each of the institutions taking part in this trial used third-generation ultra-thin cryoneedles.

Early Detection

However, ultrasound is operator dependent and its imaging quality could be influenced by several factors including patient habitus and abundant bowel gas .
One limitation pertaining to the physics of ultrasound is that ultrasound is nearly 100% reflected by an ice interface.
Thus, frozen tissue can’t be imaged, and unfrozen tissue completely enveloped by frozen tissue also cannot be imaged.
This presents an issue because posterior shadows by the edge of the ice ball may avoid the operator from seeing what area of the tumor has been treated .
Hence, ultrasound likely presents more technical challenges than MRI and CT during intraoperative imaging.

• The results of the different scans are then in comparison to help find abnormal areas.
• Hormonal therapy is also known as androgen deprivation therapy .
• Physician Data Query may be the National Cancer Institute’s (NCI’s) comprehensive cancer information database.
• A treatment clinical trial is a research study designed to assist in improving current treatments or obtain home elevators new treatments for patients with cancer.

& Sehgal, C. Overview of low-intensity ultrasound for cancer therapy.
In this procedure, your doctor will insert probes in to the prostate.
The probes are then filled with cold gases to freeze and kill cancerous tissue.
Prostate Cancer Research Highlights Obtain the latest research highlights from our prostate cancer research conducted and funded through ACS grants.
The patient is first injected with a contrast agent containing microbubbles, which helps improve the ultrasound images.
Promising early results have been reported, and further research on this technique is under way.

Once the decision has been made, the physician at the urologic oncology department will explain precisely what will happen through the procedure.
You will have to abstain from food and drinks at least six hours before the procedure.
