Prostate cancer is a type of cancer that develops in the prostate gland, which is a small walnut-sized gland located below the bladder in men. Prostate cancer occurs when abnormal cells in the prostate gland grow and divide uncontrollably, forming a tumor. The prostate gland produces seminal fluid that nourishes and transports sperm. We will explore the treatment options for prostate cancer as well as the factors determining the course of treatment.
What are the best treatment options for prostate cancer?
Treatment decisions for prostate cancer should be made in consultation with a multidisciplinary team of healthcare professionals, including urologists, radiation oncologists, medical oncologists, and other specialists. They will consider the individual’s specific case and recommend the most appropriate treatment plan tailored to their needs. Here are some common treatment options:
- Active Surveillance: Active surveillance may be an option for low-risk prostate cancer. Treatment is initiated only if there are signs of tumor growth. Regular monitoring of prostate-specific antigen (PSA) levels, digital rectal exams, and periodic biopsies are performed to track the progression of cancer.
- Surgery: Radical prostatectomy involves surgically removing the prostate gland and nearby tissues. It is typically recommended for localised prostate cancer. Different surgical techniques are available, including open surgery, laparoscopic surgery, and robot-assisted laparoscopic surgery (da Vinci system).
- Radiation Therapy: External beam radiation therapy (EBRT) and brachytherapy are common radiation treatment options for prostate cancer. EBRT delivers radiation from outside the body, while brachytherapy involves the implantation of radioactive seeds directly into the prostate. Radiation therapy may be used alone or in combination with other treatments.
- Hormone Therapy: Prostate cancer cells are often dependent on male hormones like testosterone for growth. Hormone therapy, also known as androgen deprivation therapy (ADT), aims to lower the levels of testosterone or block its effects to inhibit cancer growth. It can be achieved through medications or surgical removal of the testicles (orchiectomy).
- Chemotherapy: It is typically reserved for advanced or metastatic prostate cancer. It uses drugs to kill cancer cells or stop their growth. The most common drug is docetaxel (Taxotere), which is usually given with prednisone, a steroid medicine. Chemotherapy is usually administered intravenously and may be combined with other treatments.
- Targeted Therapy: The drugs used here specifically target cancer cells or the mechanisms that support their growth. Examples include drugs that target the androgen receptor pathway or other specific molecular targets.
- Immunotherapy: It helps stimulate the body’s immune system to recognise and attack cancer cells. Certain immunotherapy drugs, such as immune checkpoint inhibitors, have been approved for the treatment of advanced prostate cancer.
On what factors does prostate cancer treatment depend?
Prostate cancer treatment depends on several factors, including:
- Stage of Cancer: It indicates the extent of its spread, which plays a crucial role in determining the treatment approach. Prostate cancer is classified into stages ranging from I to IV, with early-stage (I and II) cancers typically having more localized growth and advanced-stage (III and IV) cancers having spread beyond the prostate.
- Gleason Score: It is a grading system that assesses the aggressiveness of prostate cancer cells based on their appearance under a microscope. It helps determine the cancer’s potential for growth and spread, influencing treatment decisions.
- PSA Levels: Prostate-specific antigen (PSA) is a protein produced by the prostate gland. Higher levels of PSA in the blood may indicate the presence of prostate cancer. PSA levels help in diagnosis, monitoring treatment response, and determining the risk of recurrence.
- Age and Overall Health: The age and general health status of the individual are considered when choosing treatment options. Younger patients with longer life expectancy may opt for more aggressive treatments, while older individuals or those with multiple health issues may choose less invasive approaches.
- Tumor Growth Rate: The rate of tumor growth and the likelihood of cancer spreading (metastasis) are evaluated to determine the appropriate treatment strategy. Faster-growing tumors may require more immediate and aggressive treatment.
- Personal Preferences: Patient preferences and values are essential in treatment decisions. Factors such as potential side effects, impact on quality of life, and individual priorities are considered when selecting the most suitable treatment approach.
Patients need to have open and thorough discussions with their healthcare team to understand their specific situation, treatment options, potential benefits, and risks. This shared decision-making process helps ensure that the chosen treatment aligns with the patient’s goals and maximizes their well-being.
