Stereotactic Body Radiation Therapy Offers A High Cure Rate For Prostate Cancer

The comparison between SBRT and other treatments

A 5 year study, which was conducted by researchers at the Harold C Simmons Comprehensive Cancer Centre in Texas, U.S.A, shows that SBRT offered higher cure rates for prostate cancers than other forms of management. This was the first trial to publish 5 year results on SBRT, and it found that the cure rate of prostate cancer was 98,6%.

This cure rate was extremely high compared to other forms of treatment such as conventional radiation therapy and surgery, which had cure rates ranging between 80-90%. Not only was the cure rate of SBRT high, but it was also non-invasive and had a quick completion rate of 5 sessions.

This then made SBRT a more effective and potent form of management for prostate cancer as compared to other available conventional treatments. These forms of management include the following:

• Prostatectomy - the prostate is surgically removed and can be done using minimally invasive procedures and robotic assistance nowadays.
• Brachytherapy - here, small rice-sized radioactive seeds are implanted into the prostate via large needles which are inserted through the skin. These seeds then release radiation directly onto the prostate.
• External beam radiation - this involves radiation of the area of the prostate. Here, 42-45 treatments are administered over a few months, for 5 days a week.

Side-effects of prostate cancer treatments 

Regarding side-effects, it was discovered that the following issues were experienced with SBRT:

• Urinary issues such as increased frequency, increased urgency and burning urine as well as rectal irritation were experienced. Importantly, it was noted that these issues were not different to those experienced from the other forms of treatment. Also, these issues seemed to resolve within 4 weeks after treatment was completed.
• There was also associated risk of long-term rectal and urinary complications, which were also comparable to other forms of treatment.
• Erectile dysfunction was also a reported issue, but this was in the case of 25% of patients which was comparably less than in other treatments.

Future studies on SBRT

The mentioned study showed the efficacy of SBRT in stage 1 and 2 prostate cancers, which are regarded as low and intermediate risk cancers. The researchers are looking to expand their study into testing the potency of SBRT in stage 3 prostate cancers.

Prostate cancer: Risk factors, Complications and Prevention

Definition

Prostate cancer is a malignancy that occurs in the prostate gland of men. The prostate is responsible for supplying semen to sperm. This cancer is usually slow growing and contained to the prostate where it never causes any further issues.

Risk factors

The following are factors which can increase the chance of developing prostate cancer:

• Age - advancing age increases the chance to develop this problem.
• Race - African men seem to have a greater chance of developing prostate cancer as compared to other races. The cancer can also be more aggressive or advanced in these men and the reason for this is still unknown.
• A family history of first-degree relatives (father, mother or siblings) with prostate or even breast cancer, increases the risk of developing prostate cancer.
• Obese men who are diagnosed with prostate cancer are more likely to have advanced prostate disease that's harder to treat.

Prevention

A person can follow certain suggestion which can possibly reduce one's risk of developing prostate cancer. These include the following:

• Dietary changes - reduce the intake of food that is highly refined as well as high in fat and sugar content. One should incorporate more fruits and vegetables as well as whole-grain foods as these contribute more to healthy living.
• Rather choose foods high in vitamins, mineral and nutrients rather than relying on supplements.
• Physical exercise - there is some evidence to show that sedentary men tend to have higher levels of PSA in their blood, which can indicate a higher risk to developing prostate cancer. One should try and combine aerobic exercises, such as walking and swimming, with weight training on most days of the week.
• Maintain a healthy weight - since obesity is a risk factor, reducing weight by increasing physical exertion and reducing calorie intake could only therefore reduce the risk of developing prostate cancer.
• High risk men should consult their doctors - certain medications could be prescribed in order to help reduce the risk of developing this issue. There are studies which suggest that medications such as finasteride and dutasteride could help reduce the associated risk. These drugs though could also increase the risk of developing more serious prostate cancers, so consultation with a doctor is vital when making this decision.

Complications

The complications of prostate cancer and the treatments associated with it may include the following issues:

• Urinary incontinence - both prostate cancer and its associated treatments may lead to urinary incontinence. 
• Erectile dysfunction - this is an issue which may resolve depending on the treatment used to manage prostate cancer. There are medications and devices though which may be used to help deal with this condition.
• Metastatic cancer -  prostate cancer tends to metastasize the the bones of the lower back and can cause pain there as well as fractures. Once prostate cancer spreads, it unfortunately can't be cured but it may still be controlled.
