A
  1. Bone scan (if pain or elevated alk phos)
  2. CT chest
  3. MRI w/ gad (for IVC and R atrium)
  4. PET or PET/CT
17
Q

Other than hematuria, abdominal mass and flank pain, what 4 other sxs might be present in a patient with Renal Cell Carcinoma if there is IVC involvement?

A
  1. LE edema
  2. Ascites
  3. Hepatic dysfunction
  4. Pulmonary emboli
18
Q

What is the treatment for a localized RCC (Stages I, II, III)?

A

Surgery is curative

19
Q

What are the treatment options (3) for advanced RCC (Stages IV)?

A

Options:

  1. Systemic therapy (Immunotherapy, molecularly targeted agents)
  2. Surgery
  3. Radiation

*treatment decisions are dependent on prognosis*

20
Q

What are the predictors of malignancy for a small renal mass, <4cm (w/ enhancement on contrast imaging, solid or complex cyst)?

A

Male sex

Increasing tumor size

21
Q

How do you manage a renal mass that is <2cm?

  • 20-40% are _____
  • 10% high grade ____
  • <1% develop ______
A
  • 20-40% are benign
  • 10% are high grade RCC
  • <1% develop mets
    *
22
Q

Management of small renal mass:

What are the chances of a renal mass that is >4cm being benign? Being high grade or advanced RCC?

A

Increased chance of malignancy!

5-10% benign

20-30% high grade or advanced RCC

23
Q

The following are steps in management of what?

  1. Urology
  2. Dedicated Renal CT or MRI, without and then with IV contrast
  3. CMP and CBC (paraneoplastic syndrome)
  4. Renal function to eval for CKD
  5. Chest imaging if malignancy risk high and concern for Mets
  6. Biopsy decision
A

Management of small renal mass

24
Q

What are the 4 management strategies of small renal masses and at what size are each indicated?

A
  1. Surgery (partial nephrectomy)
  2. Thermal ablation (if < 3cm)
  3. Surveillance (only if <2cm)
  4. <1cm =surveillance (NO biopsy)
25
Q

If you find a small renal mass < 2cm, how would you manage this?

A

Surveillance

Mets eval q3-6mo x2 years then q6-12 month

26
Q

What is the management for a renal cell mass <1cm?

A

Surveillance

(NO biopsy)

27
Q

Which renal tumor?

  • 2/3 dx before 5y/o, 95% before 10y/o
  • Sporadic (NOT genetic)
A

Wilms Tumor

28
Q

Pathology of which Renal Tumor?

•Abnormal renal development

  • Association with loss of function of tumor suppressor genes
  • solitary lesion
  • Surrounded by pseudocapsule
A

Wilms Tumor

29
Q

What is the most common clinical presentation of a wilms tumor?

A

Abdominal mass

(usually an incidental finding by a parent)

30
Q

Other than an abdominal mass, what are 4 other less common presentations for a Wilms tumor?

A

32
Q

What is the initial diagnostic study for a Wilms Tumor?

What other test(s) do you perform if you don’t find anything on the initial study?

A
  • Initial study= Abdominal ultrasound
  • If you dont find anything on u/s, you MUST order: CT or MRI w/ contrast
