Prostate Cancer Treatment
As the cancer advances, however, it can spread beyond the prostate into the surrounding tissues (local spread). Moreover, the cancer also can metastasize (spread even farther) throughout other areas of the body, such as the bones, lungs, and liver. Symptoms and signs, therefore, are more often associated with advanced prostate cancer.
In a normal situation, prostate become bigger when patient become older. It's a common evolution called benign prostatic hyperplasia. It can cause urinary troubles and may be confused with prostate cancer.
Prostate Cancer Treatment in India
The kind of Prostate Cancer Treatment is decided functions of the PSA blood level, results of rectal examination and complementary exams, and Gleason score. The treatment options for organ-confined prostate cancer or locally advanced prostate cancer usually include surgery, radiation therapy, hormonal therapy, cryotherapy, combinations of some of these treatments, and watchful waiting. A cure for metastatic prostate cancer is, unfortunately, unattainable at the present time. The treatments for metastatic prostate cancer, which include hormonal therapy and chemotherapy, therefore, are considered palliative.
The surgical treatment for prostate cancer is commonly referred to as a radical prostatectomy, which is the removal of the entire prostate gland.
Transurethral resection of the prostate (TURP) involves the removal of a part of the prostate by an instrument inserted through the urethra. It is used as an alternative to prostatectomy in patients with extensive disease or those who are not fit enough to undergo radical prostatectomy to remove tissue that is blocking urine flow.
The goal of radiotherapy is to damage the cancer cells and stop their growth or kill them. Radiation therapy can be given either as external beam radiation over perhaps six or seven weeks or as an implant of radioactive seeds (brachytherapy) directly into the prostate. In external beam radiation, high energy X-rays are aimed at the tumor and the area immediately surrounding it. In brachytherapy, radioactive seeds are inserted through needles into the prostate gland under the guidance of transrectally taken ultrasound pictures.
Cryotherapy is a new kind of treatment that consists in an internal radiation exposure. Small spheres of a radioactive element are introduced into the prostate under general anesthesia. They emit during approximately 6 months but the rays are too weak to be dangerous for persons around.
Hormone therapy is also a part of the treatment. The growth of the tumor is partly controlled by the testosterone. In the case of a metastatic cancer, treatment consists in an administration of substances that will block the action of testosterone (hormonotherapy), and so stop the growth of the tumor. It can be associated to chemotherapy if need be. Treatments available for hormonotherapy are:
- Testicles Ablation: Testosterone is secreted by the testicles and their removal leads to a decrease in testosterone blood level.
- Estrogens: These hormones decrease testosterone blood level. The most used is the diethylstilbestrol, but this drug can lead to cardiovascular disorders.
- Luteinizing Hormone-Releasing Hormone (LH-RH): It blocks he testicles' testosterone secretion.
- Anti-Androgen Drugs: These drugs block the action of all male hormones (not only testosterone), that also have a little action on the tumor growth. Adverse effects can be a loss of sexual desire and erectile dysfunction.
Technology used for Treating Prostate Cancer
Apart from surgery and chemotherapy, the new age technology used to treat prostate cancer include Radiology and Radiation Oncology, which are advanced imaging technology that can be used to detect prostate cancer.
Technologies for detection of cancer:
- Computerized Tomography (CT)
- Nuclear Medicine
- PET Fusion
- Conformal Radiotherapy (CRT)
- Robotic Surgical System
- Trilogy Image Guided Radiation Therapy System (IGRT)
- Intensity Modulated Radiation Therapy System (IMRT)
