All of the following investigations are used in FIGO staging of carcinoma cervix except ?
**Core Concept**
The FIGO (International Federation of Gynecology and Obstetrics) staging system is a standardized classification system used to stage cervical cancer, guiding treatment and prognosis. It relies on clinical evaluation and specific investigations to determine the extent of cancer spread.
**Why the Correct Answer is Right**
CECT (Contrast-Enhanced Computed Tomography) is not a recommended investigation in the FIGO staging of cervical cancer. The FIGO staging system primarily relies on clinical examination, biopsy, and specific investigations such as cystoscopy, proctoscopy, and intravenous pyelography to assess the local extent of the tumor. CECT is not included because it may provide additional information that could influence treatment decisions, but is not essential for the FIGO staging.
**Why Each Wrong Option is Incorrect**
**Option B:** Intravenous pyelography is used to assess the upper urinary tract for potential invasion by cervical cancer. It is a relevant investigation in the FIGO staging system.
**Option C:** Cystoscopy is used to evaluate the bladder for potential invasion by cervical cancer. It is a recommended investigation in the FIGO staging system.
**Option D:** Proctoscopy is used to assess the rectum for potential invasion by cervical cancer. It is a recommended investigation in the FIGO staging system.
**Clinical Pearl / High-Yield Fact**
The FIGO staging system is a clinical staging system, relying on clinical evaluation and specific investigations. It is essential to understand the recommended investigations for accurate staging and treatment planning.
