Prostate Cancer

Prostate Overview
The prostate, an exclusively male glandular organ, envelops the bladder neck
and the initial section of the urethra, contributing secretions to semen.
Conical in shape, it measures 3 cm vertically and 4 cm horizontally,
featuring five lobes: anterior, posterior, two lateral, and a median lobe.
Lesions in the prostate can lead to urinary difficulties due to its role in
urethral passage.
Prostate Gland Disorders
1. Prostatitis: Inflammation resulting from bacterial infection.
2. Benign Prostatic Hyperplasia (BPH): Non-cancerous growth, typically after
age 50.
3. Prostate Cancer: The fourth leading cause of male cancer-related deaths.
Prostate Cancer
Androgens, male sex hormones, directly influence prostate cancer growth.
Elevated hormone levels correlate with increased tumor growth. Testes
removal significantly reduces tumor size, indicating hormonal influence.
Tumor Location
Prostate cancer primarily affects the posterior lobe, while benign
enlargement occurs in other lobes.
Cancerous Gland Changes
The gland hardens, featuring an irregular surface and loss of normal lobular
structure. Histologically, prostate cancer presents as adenocarcinoma.
Tumor Growth
Prostate cancer progresses rapidly, compressing the urethra and causing
urinary difficulties.
Tumor Spread
Metastasis occurs early
1. Local spread: Cancer cells extend to lateral lobes, seminal vesicles, and
the bladder neck and base.
2. Lymphatic spread: Cells migrate to internal and external iliac lymph
nodes, progressing to retroperitoneal and mediastinal nodes.
3. Hematogenous spread: Via the periprostatic venous plexus to vertebral
veins, potentially leading to spinal vertebral involvement.
Prostate Cancer Signs and Symptoms
Symptoms vary with cancer stage
1. Asymptomatic: Small, posterior lobe tumors often discovered incidentally.
2. Mild Urinary Issues: Enlarged tumor slightly compresses urethra, leading
to frequent urges and mild difficulty urinating.
3. Painful Urination and Bleeding: Tumor spread to nearby areas results in
painful, bloody urination, often with urine dribbling.
4. Urinary Retention: Complete urethral compression causes urine retention,
possibly leading to hydronephrosis, renal failure, and complications such as
convulsions and coma.
5. Metastatic Signs: Lumbo-sacral pain, spine fractures, abdominal swelling
and pain, respiratory symptoms, weakness, and anemia may indicate metastatic
spread.
Clinical Examination
Includes rectal examination to assess the prostate, abdominal palpation for
kidney swelling, and systemic evaluation for other lesions.
Investigations
1. Blood Tests: Complete blood count, renal function tests, and serum acid
phosphatase levels.
2. Urinalysis: Examination for abnormalities.
3. Imaging: X-rays, ultrasound, CT scans, and MRI to assess tumor extent.
4. Lymphangiography: For lymphatic spread assessment.
5. Biopsy: Histopathological confirmation of cancer cells.
Treatment
• Urinary catheterization for retention, dialysis for kidney failure, and
supportive care for coma.
• Prostatectomy: Partial or radical removal of the prostate.
• Hormone Therapy: Stilbestrol or phosphorylated diethylstilbestrol to
inhibit tumor growth.
• Chemotherapy: Cyclophosphamide, cisplatin, etc.
• Radiotherapy.
• Homeopathy: Constitutional remedies like carcinocin, conium, sabal, etc.
• Yoga and meditation for supportive care
