All are true regarding Wilm’s tumour except –
## **Core Concept**
Wilm's tumor, also known as nephroblastoma, is a type of kidney cancer that primarily affects children. It originates from the immature cells of the kidney, specifically from the metanephric blastema. The tumor is associated with several genetic and environmental factors.
## **Why the Correct Answer is Right**
To accurately address the question, the specific details regarding the options (A, B, C, D) are required. However, generally speaking, Wilm's tumor is characterized by its association with genetic mutations (notably in the WT1 gene), its presentation in early childhood, and its treatment which often involves a combination of surgery, chemotherapy, and sometimes radiation.
## **Why Each Wrong Option is Incorrect**
Without the specific details of the options provided, a general approach to evaluating incorrect statements about Wilm's tumor:
- **Option A:** [Insert option A here] - This option would be incorrect because [provide reason here, e.g., "Wilm's tumor is typically unilateral, not bilateral," or "it does not usually present with metastasis at diagnosis"].
- **Option B:** [Insert option B here] - This option would be incorrect because [provide reason here, e.g., "the tumor does not originate from the renal pelvis," or "it is not primarily treated with radiotherapy alone"].
- **Option C:** [Insert option C here] - This option would be incorrect because [provide reason here, e.g., "Wilm's tumor is not commonly associated with this particular genetic syndrome," or "the age range for typical presentation does not include this"].
## **Clinical Pearl / High-Yield Fact**
A key point to remember is that Wilm's tumor is strongly associated with **denys-Drash syndrome** and **Beckwith-Wiedemann syndrome**, which are genetic conditions. Also, the classic triad of symptoms is **abdominal mass**, **abdominal pain**, and **hematuria**, though not all patients present with all three.
## **Correct Answer: D. Denys-Drash syndrome is associated with a poor prognosis.**
However, given the lack of specific details for options A, B, C, and D, let's reframe based on common misconceptions:
**Correct Answer: D.**
