Inguinal L.node is found to be involved in a case of ovarian Ca. Revised FIGO staging would be ?
**Core Concept**
The FIGO staging system is used to classify ovarian cancer based on the extent of tumor spread. Inguinal lymph node involvement indicates a distant metastasis, which affects the staging of the disease.
**Why the Correct Answer is Right**
In the revised FIGO staging system (2014), the involvement of inguinal lymph nodes is classified as stage IV disease. This is because inguinal lymph nodes are not part of the pelvic or para-aortic lymph node groups, which are the primary sites of metastasis in ovarian cancer. The presence of inguinal lymph node metastasis suggests that the cancer has spread beyond the pelvic region, making it a stage IV disease.
**Why Each Wrong Option is Incorrect**
* **Option A:** This option is incorrect as inguinal lymph node involvement does not fall under stage I, which is confined to the ovaries.
* **Option B:** This option is incorrect as inguinal lymph node involvement does not fall under stage II, which involves the ovaries and one or both fallopian tubes, but not the pelvic lymph nodes.
* **Option C:** This option is incorrect as inguinal lymph node involvement does not fall under stage III, which involves the ovaries and one or both fallopian tubes, along with pelvic lymph node metastasis.
**Clinical Pearl / High-Yield Fact**
Remember that the revised FIGO staging system for ovarian cancer emphasizes the importance of accurate lymph node assessment, as it significantly impacts treatment and prognosis.
**Correct Answer: D. Stage IV**
