Kidney Cancer

Kidney Cancer

Kidney cancer typically starts in the lining of small tubes in the kidney and may be discovered incidentally on imaging or present with blood in the urine, flank pain, or a palpable mass.

Management is stage-directed and may include partial or radical nephrectomy, ablation, targeted therapy, or immunotherapy.

The goal is cure for localized disease, preservation of renal function when possible, and coordinated long-term surveillance.

Overview And Clinical Background

Origin, types and clinical importance

Most primary kidney cancers are renal cell carcinomas arising from the renal tubular epithelium.

Subtypes (clear cell, papillary, chromophobe) differ in biology and targeted treatment sensitivity.

Common subtypeClear cell RCC is the most frequent and has characteristic vascular features.

Risk factorsSmoking, obesity, hypertension, and certain hereditary syndromes increase risk.

Natural historySmall lesions may be indolent; larger or high-grade tumors can metastasize to lung or bone.

Symptoms, Signs And Presentation

Early kidney cancer may be asymptomatic and found during unrelated imaging.

When symptomatic, patients report hematuria, flank pain, or a palpable lump; paraneoplastic syndromes occasionally appear.

HematuriaPainless blood in the urine is a classic presenting sign.

Flank discomfortDull ache or fullness around the affected kidney.

Systemic signsUnintended weight loss, fever, or fatigue may indicate advanced disease.

Diagnosis Methods And Investigations

Imaging, biopsy and staging

Diagnosis uses ultrasound, contrast CT or MRI to characterise renal masses and CT chest/abdomen/pelvis or PET for staging.

Percutaneous biopsy is used selectively to guide management when imaging is indeterminate.

Cross-sectional imagingContrast CT or MRI to evaluate size, local invasion and vascular involvement.

Image-guided biopsyCore biopsy when histology will change management or for systemic therapy planning.

Staging workupCT chest and bone scans/PET for suspected metastatic disease.

Treatment Options And Surgical Techniques

Treatment depends on size, location and stage — options include active surveillance for small lesions, partial nephrectomy to spare renal tissue, radical nephrectomy for larger tumors, ablative therapies, and systemic targeted or immune therapies for advanced disease.

Minimally invasive and robotic approaches reduce recovery time when feasible.

Nephron-sparing surgeryPartial nephrectomy removes the tumor while preserving healthy kidney tissue.

Radical nephrectomyComplete kidney removal for large or centrally located tumors.

Systemic therapyTyrosine kinase inhibitors, immune checkpoint inhibitors, or combination regimens for metastatic disease.

Recovery, Risks And Prognosis

Recovery after surgery typically spans weeks with progressive return to activity.

Prognosis is excellent for localized cancers treated early; metastatic disease prognosis has improved substantially with modern systemic therapies but requires long-term management.
