Common complications of renal cell carcinoma include [[hypertension]], [[hypercalcemia]], [[Budd-Chiari syndrome|budd-chiari syndrome]], [[hepatic vein thrombosis]], [[polycythemia]], [[renal failure]], [[metastasis]]. Prognosis is generally poor, and the 5-year mortality of renal cell carcinoma is approximately 73.2%. | |||

Overview
Common complications of renal cell carcinoma include hypertension, hypercalcemia, budd-chiari syndrome, hepatic vein thrombosis, polycythemia, renal failure, metastasis. Prognosis is generally poor, and the 5-year mortality of renal cell carcinoma is approximately 73.2%.
Natural History
- The symptoms of renal cell carcinoma usually develop in the fifth decade of life, and start with symptoms such as hematuria, flank pain and palpable abdominal mass.[1]
- If left untreated, 1.3% of patients with renal cell carcinoma may progress to develop metastatic disease.[2]
Complications
The following are possible complications of the primary tumor and its spread, associated paraneoplastic syndromes, or metastasis:[3][4][5][6]
- Hypertension
- Hypercalcemia
- Budd-Chiari syndrome
- Hepatic vein thrombosis
- Polycythemia
- Acute and chronic renal failure
- Metastasis, commonly to bones, lungs, or brain
Prognosis
The presence of the following factors may correlate with a poorer prognosis in renal cell carcinoma:[7][8][9]
- Low Komofsky performance score, a score to measure performance impairment in patients with cancer
- Elevated serum lactate dehydrogenase (LDH)
- Low hemoglobin level
- Elevated corrected serum calcium levels
Other prognostic scoring include the tumor-mode-metastasis (TNM) staging system and the Fuhrman nuclear grade.[7][10][11]
Survival
- Patients with metastatic renal cell carcinoma have a median age of survival reaching approximately 13 months. Available medical therapy, however, may significantly prolong survival of patients with metastatic disease.[7]
- Between 2004 and 2010, the 5-year relative survival of patients with kidney cancer was 73.7%.[12]
- When stratified by age, the 5-year relative survival of patients with kidney cancer was 78% and 65% for patients <65 and ≥ 65 years of age respectively.[12]
- The survival of patients with kidney cancer varies with the stage of the disease. Shown below is a table depicting the 5-year relative survival by the stage of kidney cancer:[12]
Stage | 5-year relative survival (%), (2004-2010) |
All stages | 72.4% |
Localized | 91.8% |
Regional | 64.7% |
Distant | 12.1% |
Unstaged | 32.2% |
- Shown below is an image depicting the 5-year conditional relative survival (probability of surviving in the next 5-years given the cohort has already survived 0, 1, 3 years) between 1998 and 2010 of kidney cancer by stage at diagnosis according to SEER. These graphs are adapted from SEER: The Surveillance, Epidemiology, and End Results Program of the National Cancer Institute.[12]
The following table summarizes the 5-year survival of patients according to cancer staging[7][13]:
Stage | Tumor Characteristics | Five-Year Survival |
Stage I | Tumor < 7 cm in greatest dimension, limited to kidney | 95% |
Stage II | Tumor > 7 cm in greatest dimension, limited to kidney | 88% |
Stage III | Tumor in major veins or adrenal glands, tumor within Gerota's fascia, or 1 regional lymph node involved | 59% |
Stage IV | Tumor beyond Gerota's fascia or > 1 regional lymph node involved | 20% |
