Q

What are the 4 diagnostic tests you should do in order to evaluate for metastasis of Renal Cell Carcinoma?

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
If you find a small renal mass \< 2cm, how would you manage this?
**Surveillance** Mets eval q3-6mo x2 years then q6-12 month
26
What is the management for a renal cell mass \<1cm?
**Surveillance** | (NO biopsy)
27
**Which renal tumor?** * MC primary renal cancer in **children \< 15 y/o** * 2/3 dx before 5y/o, 95% before 10y/o * Sporadic (NOT genetic)
Wilms Tumor
28
**Pathology of which Renal Tumor?** ## Footnote **•Abnormal renal development** * Association with **loss of function of tumor suppressor genes** * **_solitary lesion_** * Surrounded by **_pseudocapsule_**
Wilms Tumor
29
What is the most common clinical presentation of a wilms tumor?
**Abdominal mass** (usually an incidental finding by a parent)
30
Other than an abdominal mass, what are 4 other less common presentations for a Wilms tumor?
1. Abdominal Pain 2. **Hematuria** 3. Fever 4. Hypertension ("**F**reddy **H**ad **A** **H**amburger")
31
What is the **definitive diagnosis** for a Wilms tumor?
Histologic confirmation **(surgical excision or biopsy)**
32
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?
* Initial study= **Abdominal ultrasound** * If you dont find anything on u/s, you MUST order: CT or MRI w/ contrast
33
T/F: In a patient with a Wilms tumor, you do NOT need to evaluate the contralateral kidney
FALSE It is important to evaluate the contralateral kidney
34
**The Following diagnostic labs would be ordered for which renal tumor?** * renal function * U/A * liver function * calcium * CBC * coag studies
Wilms tumor
35
What is the treatment for a Wilms tumor? (3 steps)
1. **Refer** to pediatric cancer center 2. Chest imaging for Mets 3. **Chemo** and **surgical excision**
36
What is the prognosis of a Wilms tumor?
* 5-year survival 90% * Increased risk of premature death in adulthood due to secondary neoplasms and other late complications
37
What is a patient with **history of Wilms tumor** at increased risk of?
•Increased risk of **premature death in adulthood** due to **secondary neoplasms** and other **late complications** (i.e. infertility)
38
Surveillance for Wilms tumor after surgical excision and chemo includes what 3 diagnostic studies performed how often?
* •Includes CXR, abd u/s, chest/abd/pelvic CT * Q 6-8 weeks during therapy, q 3 months x 2 years, q 6 months x 2 years
