Question

A tumor/mass lesion of the kidney extends into the IVC, with Gerota's fascia intact. All the following are true, EXCEPT

• A. IVC invasion is a contraindication for surgery
• B. Chest X-ray to rule out pulmonary metastases
• C. Pre-op radiotherapy is not indicated
• D. Pre-op biopsy is not indicated

Hint:

RCC with an IVC thrombus, but no spread outside Gerota's fascia, is still resectable with thrombectomy.

Answer 1

The Correct Option is A

Step 1: Understanding the Question:
A kidney tumor has grown into the inferior vena cava (IVC), but the fibrous covering of the kidney, Gerota's fascia, is still intact, meaning the tumor has not spread outside the kidney's capsule of fat and fascia. We need the one statement that is false about managing this case.

Step 2: Key Concept:
This picture describes locally advanced renal cell carcinoma (RCC) with a tumor thrombus in the IVC but no extracapsular spread. RCC has a well known tendency to grow along veins as a solid tumor thrombus rather than through blood borne spread, so even a large IVC thrombus can often be removed surgically along with the kidney, especially when Gerota's fascia keeps the disease contained.

Step 3: Detailed Explanation:
Statement (A), IVC invasion is a contraindication for surgery, is false. Radical nephrectomy with IVC thrombectomy (removing the tumor thrombus from the vena cava, sometimes needing cardiopulmonary bypass for very high thrombi) is standard treatment and can be curative, so IVC involvement alone does not rule out surgery.
Statement (B), chest X-ray to rule out pulmonary metastases, is correct practice. RCC commonly spreads to the lungs, so a chest X-ray or CT chest is a routine part of staging before planning surgery.
Statement (C), pre-op radiotherapy is not indicated, is correct. RCC is relatively radioresistant, and radiotherapy has no proven role in shrinking the tumor before surgery.
Statement (D), pre-op biopsy is not indicated, is correct in most cases. When imaging is typical for RCC and the plan is surgical removal anyway, a biopsy adds risk (bleeding, tumor seeding) without changing management, so it is usually skipped.

Step 4: Final Answer:
The false statement is that IVC invasion is a contraindication for surgery, since IVC thrombectomy along with nephrectomy is the standard curative approach.
