Detailed presentation on renal cancer covering risk factors, types, clinical signs, staging, diagnostic methods, and management including surgery, chemotherapy, immunotherapy, and targeted therapy.
INTRODUCTION
• Kidney canceris one of the most common cancers of the
urinary system.
• It occurs more frequently in males than females and is usually
diagnosed between 50 and 70 years of age.
• Due to the widespread use of imaging techniques, many
kidney tumors are now detected incidentally at an early stage.
3.
DEFINITION
• Renal canceris a malignant tumor that originates in
the cells of the kidney, most commonly from the
renal tubular epithelium.
• It is characterized by uncontrolled growth of
abnormal cells that may invade surrounding tissues
and spread to distant organs.
5.
RISK FACTORS
• Theexact cause of kidney cancer is unknown; however,
several factors increase the risk:
• Cigarette smoking
• Obesity
• Hypertension
• Chronic kidney disease
6.
CONTI..
• Long-term dialysis
•Family history of kidney cancer
• Occupational exposure to chemicals (cadmium,
asbestos, petroleum products)
7.
TYPES
• 1. RenalCell Carcinoma (RCC)
• Accounts for 85–90% of cases.
• Originates from renal tubular cells.
8.
CONTI..
• 2. TransitionalCell Carcinoma
• Arises from the renal pelvis.
• Similar in behavior to bladder cancer.
9.
CONTI..
• 3. WilmsTumor
• A childhood kidney cancer.
• Usually occurs before 5 years of age.
11.
CONTI..
• 4. RenalSarcoma
• Rare tumor arising from connective tissue of the
kidney.
STAGES
• Stage I(T1, N0, M0)
• Characteristics
• Tumor is 7 cm or smaller in greatest dimension.
• Cancer is confined to the kidney.
• No lymph node involvement.
• No distant metastasis.
18.
CONTI..
• Stage II(T2, N0, M0)
• Characteristics
• Tumor is larger than 7 cm.
• Cancer remains confined to the kidney.
• No lymph node involvement.
• No distant metastasis.
19.
• Stage III
•TNM Classification
• T3, N0, M0 OR
• T1–T3, N1, M0
• Characteristics
• Cancer has spread to:
• Major veins (renal vein or inferior vena cava), OR

DIAGNOSTIC EVALUATION
• 1.History and Physical Examination
• Smoking history
• Family history
• Assessment of symptoms
CONTI..
• Chest X-ray
•Detects lung metastasis.
• Bone Scan
• Performed if bone pain is present.
30.
MANAGEMENT OF RENALCANCER (KIDNEY CANCER)
• Management depends on the stage of cancer,
tumor size, patient's age, overall health, and
presence of metastasis.
31.
CONTI..
• Surgical Management
•1. Partial Nephrectomy (Kidney-Sparing Surgery)
• Only the tumor and a small margin of healthy kidney
tissue are removed, while the rest of the kidney is
preserved.
33.
CONTI..
• 2. RadicalNephrectomy: Complete removal of the affected kidney
along with surrounding tissues.
• Structures Removed
• Entire kidney
• Perirenal (surrounding) fat
• Sometimes adrenal gland
• Nearby lymph nodes (if involved)
34.
CONTI..
• 3. CytoreductiveNephrectomy
• Removal of the primary kidney tumor even when
cancer has already spread to other parts of the
body.
CONTI..
• Chemotherapy
• Limitedeffectiveness in Renal Cell Carcinoma.
• Used mainly for rare non-RCC tumors.
• Common Drugs
• Gemcitabine
• 5-Fluorouracil
37.
CONTI..
• Immunotherapy
• Stimulatesthe immune system to attack cancer cells.
• Immune Checkpoint Inhibitors
• Nivolumab
• Pembrolizumab
• Ipilimumab
38.
CONTI..
• Targeted Therapy
•Targeted drugs block pathways responsible for tumor growth and blood vessel
formation.
• Common Drugs
• Sunitinib
• Pazopanib
• Cabozantinib
• Axitinib
39.
CONTI..
• Radiation Therapyin Renal Cancer
• In Renal Cell Carcinoma (RCC), radiation therapy is not the
first-line treatment because RCC cells are relatively resistant to
conventional radiation. The primary treatment is usually partial
nephrectomy or radical nephrectomy.
• Therefore, radiation therapy is mainly used for palliation
(symptom relief) and treatment of metastatic
