Cryosurgical Ablation Of The Prostate Is Performed For Prostate Cancer
Cryotherapy is a promising newer treatment option for prostate cancer. During the procedure, a doctor freezes prostate tissue at extremely low temperatures. This causes cancer cells to die.After skin cancer, prostate cancer is the most common cancer in the male population. Doctors diagnose almost 250,000 new cases every year in the United States.More traditional treatment approaches, such as radiation therapy and surgery to remove the prostate, have various negative effects that can affect sexual function and quality of life. However, because cryotherapy is minimally invasive and causes fewer long-term problems, doctors may recommend it to treat early stage prostate cancer.This article looks at cryotherapy for prostate cancer, including its benefits and risks. It also explores some alternative prostate cancer treatment options. Share on PinterestThis technique consists In applying an extreme cold via one or various needles cryoprobes to destroy the sick tissues, including the cancer cells. A series of freezing and defrosting stages of the tumors enable their destruction.Cryotherapy involves using cold temperatures to freeze and destroy tissue affected by cancer. The procedure is also known as cryoablation or cryosurgery. It uses liquid nitrogen, liquid nitrous oxide, or argon gas to achieve the freezing temperature necessary for treatment.Cryotherapy can help treat skin conditions and relieve pain and inflammation. Additionally, cryotherapy may be effective in bone, cervical, liver, and prostate cancer.In prostate cancer, doctors use cryotherapy as a minimally invasive procedure to target either the whole prostate or specific parts of the prostate.Using ultrasound technology, a doctor inserts small probes called cryoneedles into the prostate and special needles to check the temperature. They then insert cool gas that freezes and damages the prostate gland, killing cancer cells and helping prevent disease progression. Because the procedure is less invasive than traditional therapies, people typically experience less pain and shorter hospital stays.There have been few head-to-head trials comparing cryotherapy with traditional therapies for prostate cancer. However, one 2010 study evaluated 244 people receiving external beam radiation therapy (EBRT) compared with cryotherapy. The study analyzed the effects of each treatment in terms of disease progression and found a slight difference between the two treatment groups, noting significantly fewer positive biopsies after cryoablation than after radiation therapy.A 2020 study compared cryotherapy with surgery. Although surgery had the best tumor control, cryotherapy was beneficial in lower risk groups. In these people, cryotherapy had reasonable tumor control and caused minimal side effects.These results suggest that cryotherapy is an effective treatment option for certain types of prostate cancer. The American Urology Association publishes guidelines with recommendations for prostate cancer treatment. The guidelines recommend cryotherapy for those who have low or intermediate risk prostate cancer. Oncologists may use cryotherapy:in prostate cancer that has not spread outside of the prostate gland to cure the cancerin prostate cancer that has spread to help reduce symptomsin prostate cancer that has been unresponsive to other therapiesin people who cannot undergo surgery or radiation therapyCryotherapy can be a suitable option for some people, as it is minimally invasive and effective in specific individuals. The following sections look at some benefits in more detail.Minimally invasiveOther procedures, such as surgery and radiation therapy, are complex and involved. They may include preparation, hospital stays, side effects, and complications post-procedure. Cryotherapy typically has fewer side effects and requires a shorter recovery time.EfficacyAlthough cryotherapy requires more research, it seems that the procedure is highly effective for some individuals.A 2010 study evaluated the effectiveness of treatments in localized prostate cancer. It found minor differences in disease progression with cryotherapy versus radiation therapy.However, a 2020 study found no difference in cancer-related death between cryotherapy and prostatectomy.As with any procedure, cryotherapy has some potential risks. Cryotherapy can cause short-term side effects, such as:Some long-term side effects of cryotherapy include:difficulty urinatingerectile dysfunctiona hole developing between the urinary tract and the rectumnarrowing of the urinary tractshedding of dead tissue in the urinary tractEfficacyAlthough cryotherapy can be effective for certain people, it is not an ideal treatment option for everyone. For this reason, guidelines recommend cryotherapy only for people with low and medium risk prostate cancer.Typically, doctors do not recommend cryotherapy for individuals with progressive disease.In a 2014 study of 108 people with prostate cancer, cryotherapy was an effective and minimally invasive treatment for well-selected cases of prostate cancer. In addition, the authors note that the biochemical progression-free survival (BPFS) was 96.4% for low risk participants and 91.2% for medium risk participants. BPFS means that prostate-specific antigen (PSA) levels, which are often elevated in those with prostate cancer, stayed below a certain level.Other treatment options are available. The treatment that a doctor recommends depends on factors specific to the person, such as how advanced their condition is and how potential side effects would affect them.People who have low risk prostate cancer typically undergo active surveillance, or watchful waiting. On the other hand, advanced prostate cancer may require removal of the prostate, called radical prostatectomy, or radiation therapy.These techniques are well-established and effective, but they may have adverse effects and effects on quality of life. This has led to the development of new treatment options, including cryotherapy.The sections below look at active surveillance, radical prostatectomy, and radiation therapy in more detail.Active surveillanceActive surveillance is a popular option for people with low risk prostate cancer, which may include small tumors and slow-growing cancer. It does not involve procedures or medications. Instead, a doctor monitors the cancer frequently for any signs of progression.The doctor checks specific metrics, such as the Gleason score and PSA level. If either of these increases, it may indicate the need for further treatment. However, if there are no changes, the doctor may continue to monitor disease progression.The reason for withholding medical intervention is that it can prevent treatment effects on the individual’s sexual, urinary, or bowel function.Radical prostatectomyRadical prostatectomy involves surgically removing the prostate and surrounding tissue. It is a standard treatment option when trying to cure prostate cancer that has not spread.The surgery removes the entire prostate gland and surrounding tissue either through open radical prostatectomy or laparoscopically. These procedures differ in technique, potential side effects, and recovery.Radiation therapyRadiation therapy uses high energy X-rays to kill cancer cells or prevent them from growing. There are two main types of radiation therapy: EBRT and brachytherapy.In EBRT, a radiologist sends radioactive beams directly to a cancerous tumor. Certain types of EBRT have precise radiation doses and directions, which decreases damage to healthy tissue and nearby organs.In brachytherapy, radiation does not have to pass through other tissues to get to its target. Instead, brachytherapy utilizes a radioactive substance known as a seed that a doctor implants in or near the cancerous tumor.Doctors can use EBRT and brachytherapy separately or together for maximal treatment effect.Cryotherapy involves using cold temperatures to help treat many types of medical conditions and cancers, including prostate cancer.Cryotherapy may be an effective option for people with low or intermediate risk prostate cancer.Doctors may recommend this treatment option because it is minimally invasive and causes few side effects. However, like any procedure, there are some risks, including tissue damage or problems with the urinary tract. Other treatment options include surgery to remove the prostate, radiation therapy, and active surveillance.
