Renal%20cancer Management
Monitoring
- Management option for patients with stage T1 kidney tumor
- Patients with tumors <2 cm, T1a masses ≤4 cm with predominantly cystic component, or clinical stage T1 masses at risk for death or morbidity if managed aggressively
- May also be considered in select asymptomatic patients with favorable-risk ccRCC
- The initial monitoring of tumor size by serial abdominal imaging [eg ultrasound (UTZ), computed tomography (CT) or magnetic resonance imaging (MRI) scan] with timely intervention reserved for tumors showing clinical progression during follow-up
- Alternative strategy for elderly patients, patients with short life expectancy, and significant comorbidities
- May utilize renal biopsy for surveillance and should include periodic metastatic survey including hematologic exams and chest imaging if with tumor growth
Follow Up
Stage I (pT1a)
During Active Surveillance
- Annual history and physical exam
- Annual laboratory tests as clinically indicated
- Abdominal computed tomography (CT) or magnetic resonance imaging (MRI) within 6 months of surveillance initiation, then CT, MRI, or ultrasound (UTZ) at least annually
- MRI with contrast if not contraindicated
- Annual and baseline chest X-ray or CT to assess for pulmonary metastases
- Biopsy of renal mass may be considered at start of surveillance or during follow-up as clinically indicated
After Ablative Techniques
- Annual history and physical exam
- Annual laboratory tests as clinically indicated
- Abdominal CT or MRI at 3-6 months after ablative therapy unless otherwise contraindicated then CT, MRI or UTZ annually for 5 years or longer as clinically indicated
- Annual chest X-ray or CT to assess for patients with biopsy-positive low-risk RCC, nondiagnostic biopsies, or even without prior biopsy
Stage I (pT1a) and (pT1b)
After Partial or Radical Nephrectomy
- Annual history and physical exam
- Annual laboratory tests as clinically indicated
- Baseline abdominal CT or MRI (preferred) or UTZ within 3-12 months post-surgery then annually for 3 years or longer as clinically indicated
- Chest X-ray or CT annually for at least 5 years, then as clinically indicated
- May decrease follow-up interval or may choose a more rigorous technique modality if with positive margins or adverse pathologic features
Stage II or III
After Radical Nephrectomy
- History and physical exam every 3-6 months for 3 years, then annually up to 5 years and then as clinically indicated thereafter
- Comprehensive metabolic panel and other test as indicated every 6 months for 2 years, then annually up to 5 years then as clinically indicated thereafter
- Baseline abdominal CT or MRI within 3-6 months, then CT, MRI or UTZ every 3-6 months for at least 3 years then annually up to 5 years; as clinically indicated thereafter
- Baseline chest CT within 3-6 months after radical nephrectomy with continued imaging (CT or chest x-ray) every 3-6 months for at least 3 years and then annually up to 5 years
- May consider imaging beyond 5 years depending on patient characteristics and tumor risk factors
- Pelvic imaging, CT or MRI of the head or MRI of spine, and bone scan, as clinically indicated
Relapsed or Stage IV and Surgically Unresectable Disease
- History and physical exam every 6-16 weeks for patients receiving systemic therapy, or more frequently as clinically indicated and adjusted for the type of systemic therapy the patient is receiving
- Required laboratory examinations based therapeutic agents being used
- CT or MRI imaging to assess baseline pretreatment or prior to observation
- May consider follow-up imaging every 6-16 weeks or as deemed appropriate based on patient's clinical status, rate of disease change and sites of active disease
- Consider CT or MRI of the head, MRI of spine, and bone scan, as clinically indicated
After Adjuvant Therapy
- Same follow-up instructions as stage II or III
Long-term Follow-up
- Should be based on assessment of patient factors eg mortality, risk factors for RCC, performance status, patient preference
- Annual history and physical exam for evaluation of metastasis risk or treatment sequelae
- Annual laboratory test after surgery to evaluate renal function and glomerular filtration rate
- May consider abdominal imaging with increasing intervals if with low but significant risk for metachronous tumors or late recurrences
- May consider chest imaging in patients with high-stage RCC and to increase intervals if with low but significant recurrence risk
