What is prostate and kidney cancer?

Overview of the Condition

What is prostate and kidney cancer?

Prostate cancer is one of the most common cancers in men and originates in the prostate gland. It is often detected early and grows slowly, with treatment options including surgery, radiation therapy, or active surveillance. 1Advanced disease may be difficult to cure, but treatment can slow progression and improve survival.

Kidney cancer originates in the kidneys, with renal cell carcinoma being the most common type in adults. It is increasingly detected incidentally through imaging techniques and is often diagnosed at an early, localized stage.

Why is it important?

Prostate cancer is seen in ~12% of patients in India, whereas kidney cancer accounts for ~30% of cases. Early identification is important, as cancer cells can invade surrounding tissues and spread to distant organs, leading to metastatic disease.

Causes / Why It Happens

Prostate and kidney cancers develop due to DNA changes that cause abnormal cell growth and survival, leading to uncontrolled accumulation of cancer cells.

Risk factors

Prostate Cancer Risk Factors

• Age >50 years
• Family history
• Inherited gene changes
• Obesity
• Smoking
• Chemical exposure

Kidney Cancer Risk Factors

• Older age
• Smoking
• Obesity
• Hypertension
• Inherited disorders
• Family history of kidney cancer

Symptoms

Prostate Cancer Symptoms

• Blood in urine or semen
• Increased urinary frequency
• Difficulty initiating urination
• Nocturia
• Urinary incontinence
• Back or bone pain
• Erectile dysfunction
• Fatigue, weight loss, and limb weakness in advanced disease

Kidney Cancer Symptoms

• Blood in urine
• Persistent side or back pain
• Loss of appetite
• Fatigue
• Unexplained weight loss

Treatment Options

Prostate cancer

• Radical prostatectomy: Surgical removal of the prostate gland to treat localized cancer.
• Radiation therapy: Uses high-energy radiation to destroy cancer cells.
• Active surveillance: Regular monitoring of low-risk cancer without immediate treatment.
• Hormone therapy: Reduces male hormones to slow the growth of advanced prostate cancer.

Kidney cancer

• Radical nephrectomy: Surgical removal of the entire kidney and surrounding tissues to treat localized kidney cancer
• Partial nephrectomy: Removal of the tumor while preserving the healthy part of the kidney
• Ablation therapy: Uses heat or cold energy to destroy small kidney tumors
• Targeted therapy/Immunotherapy: Uses medicines to block cancer growth or enhance the immune response against cancer

Tests before the surgery

Prostate cancer

• Prostate cancer screening commonly includes a prostate-specific antigen (PSA) blood test and digital rectal examination. Screening discussions are generally recommended around age 50, or earlier in individuals with higher risk factors such as family history

Kidney cancer

• Kidney cancer diagnosis includes blood and urine tests, imaging studies such as ultrasound, CT or MRI, and occasionally biopsy. Staging ranges from stage 1 (localized disease) to stage 4 disease with spread beyond the kidney or metastasis.

What is radical prostatectomy and radical nephrectomy and why is it done?

• Radical prostatectomy: Performed to remove localized prostate cancer and prevent disease progression or spread
• Radical nephrectomy: Performed to remove kidney cancer involving the entire kidney and surrounding tissues to achieve cancer control

Procedure Overview

Step-by-step

Radical prostatectomy:

• Removes the entire prostate gland and seminal vesicles for prostate cancer treatment
• Surrounding tissues such as lymph nodes and fat may also be removed
• The urethra is reattached to the bladder after prostate removal
• Can be performed as open or robotic-assisted surgery, including single-port approaches

Radical Nephrectomy:

• Surgical access to the kidney through open, laparoscopic, or robotic approach
• Removal of the entire kidney
• Removal of surrounding structures such as the ureter, adrenal gland, or nearby lymph nodes if required
• Closure of the surgical incision after achieving bleeding control

Time required

• 2-4 hours

Risks, Benefits and Hospital Stay

Risks and Complications

Radical Prostatectomy Risks

• Bleeding and possible blood transfusion
• Infection, bruising (hematoma), blood clots, or seroma formation
• Urinary incontinence or urine leakage (urinoma)
• Dry orgasm and erectile dysfunction
• Penile shrinkage or lymphocele formation

Radical nephrectomy risks

• Bleeding
• Infection
• Injury to nearby organs
• Pneumonia after surgery
• Anesthesia-related complications
• Rare risk of kidney failure

Benefits and Expected Outcomes

Radical prostatectomy

• Prostatectomy helps treat prostate cancer and enlarged prostate
• It may improve urinary symptoms and reduce the need for long-term medications for enlarged prostate

Radical nephrectomy

• Removes kidney cancer or severely damaged kidney tissue
• Helps prevent cancer progression or spread
• Relieves pain, bleeding, or other kidney-related symptoms
• May improve overall kidney and urinary health with a healthy remaining kidney

Duration of Hospital Stay

• Radical prostatectomy: 1–3 days
• Radical nephrectomy: 2–5 days

Recovery, Lifestyle and Follow-up

Recovery and Aftercare

Radical prostatectomy:

• Most patients regain good urinary control within 6–12 weeks after prostatectomy
• Recovery may take up to 12–18 months after radical prostatectomy in some patients
• Pelvic floor therapy may be recommended for persistent urinary leakage

Radical nephrectomy:

• Avoid contact sports to reduce the risk of kidney injury
• Maintain a balanced diet with limited salt intake and adequate hydration
• Maintain a healthy weight through proper diet and regular exercise

When to Contact a Doctor

Radical prostatectomy:

• Seek medical attention for heavy bleeding, fever, wound infection, severe pain, urinary problems, or abnormal wound drainage

Radical nephrectomy:

• Fever or signs of infection
• Heavy bleeding or abnormal wound drainage
• Severe pain or swelling
• Difficulty urinating
• Shortness of breath or worsening general condition

Follow-up

Radical prostatectomy:

Radical prostatectomy:

• Schedule regular follow-up visits to monitor recovery and PSA levels after prostatectomy

Radical nephrectomy:

• Attend regular follow-up visits to monitor recovery, kidney function, and overall health
• Imaging tests and blood tests may be performed to assess the remaining kidney and detect recurrence if cancer was present

Myths and Facts

Myth 1: Radical prostatectomy is completely performed by a robot.

Fact: The surgeon performs and controls every step of the robotic-assisted radical prostatectomy procedure.

Myth 2: Radical prostatectomy removes only part of the prostate.

Fact: Radical prostatectomy removes the entire prostate gland and seminal vesicles.

Myth 3: Removing one kidney always causes kidney failure.

Fact: Most people live healthy lives with one functioning kidney.

Myth 4: Radical nephrectomy is always performed as open surgery.

Fact: It can also be performed using laparoscopic or robotic-assisted minimally invasive techniques.
