Teaching Points
- Imaging plays a key role in renal cell carcinoma (RCC) staging to plan the most appropriate therapy
- The American Joint Committee on Cancer’s Tumour, Node, Metastasis (TNM) classification is currently the most widely used staging system 1-3
- Contrast-enhanced CT of the abdomen is the primary investigation in RCC staging 4,5
- MRI has a similar staging accuracy to CT, however, it is generally only used when CT is contraindicated, for further tumour characterisation when findings are equivocal on CT, or in patients who require recurrent imaging (e.g. young patients with hereditary syndromes affecting the kidneys such as Von-Hippel Lindau) 4
- CT of the chest is useful when there is suspicion of pulmonary metastases and is routinely performed in RCC staging at some centres 3
- Most bone and brain metastases are symptomatic at diagnosis and therefore bone and brain imaging is usually only performed when indicated 3
hs1
Staging of Renal Cell Carcinoma (RCC)
- Accurate pre-operative staging is important to determine the most appropriate treatment and to estimate prognosis
- The American Joint Committee on Cancer’s Tumour, Node, Metastasis (TNM) classification is the most widely used RCC staging system, having largely replaced the Robson classification 6-8
- Staging of the primary tumour (T stage) requires identification of the tumour: 9,10
- Location
- Size
- Organ confinement
- Presence and extent of tumour invasion or thrombus into the renal vein and inferior vena cava (IVC)
- Assessment of lymph node involvement (N stage) and metastatic disease (M stage) are also important 9,10
- Tumour size is critical in staging RCCs that are confined to the kidney
- Smaller tumours confer a significant survival benefit over larger tumours and partial nephrectomy can be considered 6
- Extrarenal tumour extension into perinephric or renal sinus fat, and venous infiltration/thrombus (T3 or higher) are negative prognostic factors 6
- Metastatic lesions are found in 20-30% of patients at time of diagnosis 11
- The most common sites of distant metastases are the lungs, bone, retroperitoneal and mediastinal lymph nodes, liver, and brain 6
- There are a number of different histologic subtypes of tumour including: 1,12
- Clear cell (75-85%)
- Papillary (10-15%)
- Chromophobe (4-5%)
- Different subtypes are associated with different frequency and patterns of metastatic spread. This has implications for therapy and prognosis 3,13-15
- Treatment of RCC can include: 3,12,19-21
- Partial nephrectomy - preferred in organ-confined tumours up to 7cm (T1a-b) to better preserve general kidney function and lower the risk of developing metabolic or cardiovascular disorders
- Radical nephrectomy - recommended for T2 and above tumours
- Radiofrequency ablation or cryoablation to small cortical tumours - especially in patients who are frail, with high surgical risk, a solitary kidney, compromised renal function, hereditary RCC or multiple bilateral tumours
- Active surveillance in elderly patients with significant co-morbidities or with a short life-expectancy with a solid renal tumour <4cm
- Systemic chemotherapy
- Radiotherapy for palliation and symptom relief, particularly in unresectable or recurrent disease

hs2
Computed Tomography (CT) abdomen
- Contrast-enhanced multi-detector CT of the abdomen is the first line imaging investigation to characterise and stage the primary tumour, nodal and distant metastases 6,22-24
- Overall staging accuracy is estimated to be at least 90% 25-27
- CT is accurate in estimating tumour size, although often overestimates size by 2-3 mm compared to histopathology 28-33
- Although CT can identify perinephric fat and renal sinus invasion with relatively high sensitivity (75-100%), specificity is poor (44-50%). Perinephric stranding can occur due to other causes such as perinephric oedema, vascular engorgement and previous inflammation from stone disease, fibrosis, etc. MRI is thought to have similar or superior accuracy 28,34,35
- MRI was previously thought to be superior in detecting vascular invasion, however, modern CT performs equally as well with a sensitivity of 84-100% and accuracy of 78-96% for identifying renal vein involvement 2,28,36-38
- Identification of lymph node metastases on CT is usually based on size (>10mm) which is associated with a high false positive rate mainly due to reactive hyperplasia. Metastatic spread to non-enlarged nodes is often missed. CT has a sensitivity of 77% and specificity of 82% for lymph node positivity on histopathology 9
- CT can accurately differentiate between benign and metastatic adrenal masses in patients with RCC. CT has a high negative predictive value for adrenal gland metastases (99-100%) but a low positive predictive value (26-73%) 39
- CT also has a limited positive predictive value (40%) for detecting invasion into other adjacent organs such as colon, pancreas, liver, spleen, etc.
- Although not strictly part of the staging system, CT can accurately assess invasion into the renal collecting system which may be important for treatment planning 40,41
- Including the pelvis in a routine staging examination is of limited value and unlikely to change management except in rare instances of ectopic kidneys located in the pelvis 6
hs3
Plain Chest Radiograph (CXR)
- Given that the most common site of metastasis is the lungs, staging should include imaging of the chest 2
- There is current controversy as to whether this should be in the form of plain chest radiography or chest CT
- CXR is useful as a screening tool to detect pulmonary metastasis, particularly in stage T1 disease when the overall incidence of pulmonary metastases is less than 5% 6,42
- Small pulmonary metastases are easily missed on chest radiographs and therefore in high-risk patients chest CT is preferred 5,6
- A study by Lim et al. to evaluate the role of chest CT concluded that plain chest radiography is sufficient for pulmonary staging in patients with small tumours (T1). For patients with a nodule on chest radiograph, with chest symptoms suggestive of endobronchial metastasis, or with extensive regional disease a chest CT is preferred 43
- Current National Comprehensive Cancer Network (America) guidelines recommend a chest radiograph in the initial staging workup, however, European guidelines recommend chest CT as a routine 5,19,44
hs4
Magnetic Resonance Imaging (MRI) abdomen
- MRI is generally used as a problem-solving tool rather than a first-line imaging modality for RCC staging due to its higher cost, lower availability, and increased complexity. It is also used when CT is contraindicated (e.g. pregnancy or severe allergy to iodinated contrast medium) or in patients who require recurrent imaging (e.g. young patients with hereditary syndromes affecting the kidneys such as Von-Hippel Lindau, tuberous sclerosis) 6,19,25,45
- Provides excellent soft-tissue contrast resolution and similar staging accuracy to CT
- 78-87% for MRI compared to 80-83% for CT 25,46-49
- Useful in lesions that have equivocal contrast enhancement on CT and haemorrhagic lesions
- Both MRI and CT demonstrate good agreement with surgical T-stage and M-stage. They are both poor in evaluating N-stage because nodal involvement is generally based on size criteria and metastatic spread to normal sized lymph nodes is often missed 50,51
- Both contrast-enhanced CT and MRI have equal sensitivity in detecting venous involvement, however, when there are equivocal findings for venous thrombus on CT, MRI may still be helpful 5,6,52
- MRI is superior in assessing the cranial extent of venous thrombus as CT does not always demonstrate sufficient opacification of the IVC to accurately evaluate extension 45,53,54
- MRI is superior to CT in detecting involvement of the renal capsule, perinephric fat, and Gerota’s fascia. Therefore, MRI may be useful to delineate between stage T2 and T3a, as well as T3 and T4 when this is not adequately defined on CT 36,45,55
- MRI can also distinguish benign from malignant renal tumours with a sensitivity of 86% and specificity of 78%, and can accurately differentiate clear cell from papillary RCCs 13,14,50,56-58
hs5
Doppler Ultrasound (US)
- When venous extension is not clearly defined on CT and MRI is unavailable, Doppler US can be used as a complementary technique to assess venous extension into the renal vein, IVC or right side of the heart 59
- Doppler US is, however, inferior to MRI for detecting venous thrombus with a sensitivity of 75% and specificity of 96% for US compared to 86-94% and 75-100% respectively for MRI 4
- US can also be useful to differentiate solid and cystic renal masses 6,60
- Limitations of US include:
- Bowel gas and large body habitus often limit visualisation of the renal vein, IVC and retroperitoneal lymph nodes 26,45,55
- The primary mass may be incompletely visualised
- Acoustic shadowing can occur from partially calcified cysts/masses
- Haemorrhagic cysts can demonstrate variability in echogenicity
- Isoechoic small renal tumours can be missed
- US is therefore rarely used for local staging of RCC 6
hs6
Computed Tomography (CT) Chest
- The lungs are the most common site for distant metastases 44
- CT of the chest is the most accurate imaging modality to detect small pulmonary metastases and metastases to mediastinal lymph nodes 6
- Currently, no clear consensus exists as to whether CT chest should be performed as part of the routine RCC staging workup or whether plain chest radiography is sufficient
- The European Association of Urology and the European Society for Medical Oncology guidelines recommend that all patients have a staging CT chest 19
- American guidelines recommend that plain chest radiography should be performed for all patients and CT chest should be reserved for those patients with a high risk of pulmonary metastases or with suspicious findings on chest radiograph 6,44
- Risk of pulmonary metastasis increases as the size of the primary tumour increases and, although there is no universally accepted criteria, chest CT is justified for larger primary tumours, when the plain chest radiograph is suspicious or positive, or when the patient has chest symptoms 5,6,44
- Larcher et al. reviewed CT chest findings in 1946 patients with RCC and concluded that preoperative chest CT could be avoided in patients with favourable RCC clinical characteristics at diagnosis because of their extremely low risk of pulmonary metastases. They proposed a system of determining preoperative risk based on T stage, N stage, presence/absence of systemic symptoms, platelet and haemoglobin counts 44
- They propose that patients with ≥ T1b tumours, patients with N1 tumours, patients with systemic symptoms or patients with anaemia and thrombocytopaenia should be selected for chest CT 44
- Using their cut-off criteria, a negative chest CT would be spared in 37% of cases while a positive chest CT would be missed in 0.2% of cases 44
hs7
Bone Scan
- Not recommended as a routine part of RCC staging 21,61,62
- Bone metastases are seen in approximately 30% of patients with metastatic disease and are symptomatic in the majority of patients 61
- The European Association of Urology and National Comprehensive Cancer Network (America) guidelines recommend a preoperative staging bone scan only in patients with bony symptoms, with advanced disease, or with abnormal laboratory findings (e.g. elevated alkaline phosphatase) 5,6,26,61
- Based on these guidelines, however, the decision to perform a bone scan remains a subjective assessment 61
- Larcher et al. performed a study of 2008 patients with RCC to determine the risk of a positive bone scan using preoperative variables such as T stage, N stage, presence/absence of symptoms, platelet and haemoglobin counts. They determined that when performing bone scans only in those patients with an estimated risk of a positive result of 5% or above, negative bone scans could be avoided in 80% of patients and 2% of positive bone scans would be missed 61
hs8
MRI brain or contrast-enhanced CT scan of the head
- Brain metastases are seen in up to 17% of patients with metastatic RCC and most of these patients have neurological symptoms 6
- Therefore patients with acute neurological signs or symptoms should have a MRI of the brain or a contrast-enhanced CT scan of the head 5,6
- There is no evidence to justify the routine use of brain MRI, however, it can be used to detect asymptomatic occult brain metastases in patients who have advanced RCC 6
