Kidney Cancer: Early Detection and Modern Treatment

Kidney cancer is among the 10 most common cancers in both men and women, with approximately 80,000 new cases diagnosed each year in the United States. The encouraging news: most kidney tumors today are found incidentally on imaging at an early, highly curable stage. Dr. Christopher Vendryes, MD treats kidney cancer with state-of-the-art minimally invasive techniques.

Early Warning Signs

Most early kidney cancers are silent. When symptoms occur, they include blood in the urine, persistent flank or back pain, an abdominal mass, unintentional weight loss, fatigue, and unexplained fever. Many cancers are now found incidentally on CT scans done for other reasons.

Risk Factors

Smoking, obesity, high blood pressure, chronic kidney disease, long-term dialysis, family history, and occupational exposure to certain chemicals (cadmium, trichloroethylene) all increase risk.

Diagnosis

Diagnosis begins with imaging — a contrast-enhanced CT or MRI clearly identifies most renal masses. Unlike many cancers, biopsy is not always required before treatment because imaging characteristics often make the diagnosis.

Treatment Options

For small tumors (less than 4 cm), partial nephrectomy — removing only the tumor while preserving the kidney — is the gold standard. Larger tumors may require radical nephrectomy. Both can be performed robotically through small incisions with faster recovery and excellent oncologic outcomes.

Active Surveillance and Ablation

For elderly patients or those with small, slow-growing tumors, active surveillance with serial imaging is appropriate. Thermal ablation (cryoablation or radiofrequency ablation) offers a minimally invasive alternative for selected small tumors.

Advanced Kidney Cancer

Even metastatic kidney cancer has seen revolutionary advances. Targeted therapies and immunotherapy (immune checkpoint inhibitors) have dramatically improved survival for advanced disease.
