A lady presented with carcinoma endometrium involving >50% of myometrium extending to vagina and positive peritoneal cytology but no involvement of para aortic and pre aortic nodes. What is the stage of disease
**Core Concept**
The question is testing the staging of endometrial carcinoma, specifically according to the FIGO (International Federation of Gynecology and Obstetrics) system. This system is used to classify the extent of cancer spread in the uterus and surrounding tissues.
**Why the Correct Answer is Right**
The correct answer is based on the presence of tumor in the myometrium, vaginal involvement, and positive peritoneal cytology. According to the FIGO staging system, cancer that invades the myometrium and extends to the vagina is classified as stage III. Positive peritoneal cytology is also an indicator of stage III disease, as it suggests the presence of cancer cells in the peritoneal cavity. The absence of involvement of para aortic and pre aortic nodes is not a criterion for staging in this case, as the question specifies the extent of local spread.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because it would imply a stage that is too early, taking into account the deep myometrial invasion and vaginal involvement.
**Option B:** This option is incorrect because it would imply a stage that is too advanced, as the para aortic and pre aortic nodes are not involved.
**Option C:** This option is incorrect because it would imply a stage that is too early, as the positive peritoneal cytology indicates a more advanced stage.
**Clinical Pearl / High-Yield Fact**
When staging endometrial carcinoma, it's essential to remember that the presence of deep myometrial invasion and vaginal involvement indicates a more advanced stage, even if the lymph nodes are not involved.
**Correct Answer:** III. Stage III endometrial carcinoma.
