What is PRCC
PRCC accounts for 10–15% of renal cell carcinomas.
- It arises from renal tubular epithelial cells.
Microscopically, tumor cells form finger-like papillary structures (hence the name).
Two subtypes:
Type 1 → smaller cells, better prognosis.
Type 2 → larger eosinophilic cells, more aggressive, worse prognosis.
Risk Factors
Hereditary:
- Hereditary Papillary RCC (linked to MET proto-oncogene mutations).
Acquired:
- Male sex (more common in men).
- Smoking, obesity, hypertension.
- Chronic kidney disease & dialysis patients → especially risk of Type 1 PRCC.
Symptoms
Like other kidney cancers, PRCC may remain silent for long. When present:
- Hematuria (blood in urine).
- Flank or back pain.
- Palpable mass in abdomen.
- Systemic: weight loss, fever, fatigue, night sweats.
- Like other kidney cancers, PRCC may remain silent for long. When present:

- Flank or back pain.
- Palpable mass in abdomen.
- Systemic: weight loss, fever, fatigue, night sweats.
Complications
- Metastasis to lungs, liver, bones, lymph nodes.
- Renal vein thrombosis.
- Kidney failure if bilateral or associated with end-stage renal disease.
Diagnosis
- Ultrasound → initial detection.
- CT/MRI → shows papillary tumor with lower vascularity compared to clear cell RCC.
- Urine tests → detect hematuria.
- Biopsy (rare, usually surgical specimen).
- Genetic testing in hereditary cases (MET mutation).
Conventional Treatment
Localized disease:
- Radical nephrectomy (entire kidney removal).
- Partial nephrectomy for small tumors.
Advanced/metastatic PRCC:
Targeted therapy:
- MET inhibitors (Cabozantinib, Crizotinib).
- VEGF inhibitors (Sunitinib, Sorafenib).
- Immunotherapy: PD-1 inhibitors (Nivolumab, Pembrolizumab).
PRCC usually responds less well to VEGF-targeted drugs compared to clear cell RCC. MET inhibitors are more specific.
Prognosis
- Type 1 PRCC → relatively good prognosis.
- Type 2 PRCC → aggressive, higher chance of progression & metastasis.
- Survival depends on stage and type.
Homeopathic Perspective
Like clear cell RCC, primary treatment is surgery + targeted therapy.
Homeopathy helps as supportive care:
- Improve vitality, immunity, mental calmness.
- Reduce side effects of targeted therapy (fatigue, nausea, skin issues).
- Address constitutional cancer tendency.
Useful Homeopathic Remedies
Constitutional & Cancer Remedies
Carcinosinum → hereditary cancer background, sensitive constitutions.
Conium → slow, indurated tumors, glandular involvement.
Thuja → growths with sycotic background.
Cundurango → ulcers and cancer support remedy.
Symptom-Based Remedies
Arsenicum Album → anxiety, restlessness, burning pains.
Phosphorus → hematuria, bleeding tendency, weakness.
Hydrastis → cachexia, weakness, poor appetite in cancer.
Belladonna → sudden pain, congestion.
Summary
Papillary RCC is the second most common kidney cancer, with two subtypes (Type 1 = better, Type 2 = worse).
- It often presents with blood in urine, flank pain, or abdominal lump.
- Treatment is surgery if localized, and targeted + immunotherapy if advanced (especially MET inhibitors for hereditary PRCC).
Homeopathy supports recovery, reduces side effects of modern therapy, and strengthens immunity with remedies like Carcinosinum, Conium, Thuja, Arsenicum.
