**Core Concept**
Surgical staging in ovarian cancer involves assessing the extent of disease spread, including lymph node involvement. Inguinal lymph nodes are not a typical site for ovarian cancer metastasis, as ovarian cancer primarily spreads through lymphatic routes in the pelvic and para-aortic regions.

**Why the Correct Answer is Right**
The correct answer is related to the concept that ovarian cancer primarily spreads through lymphatic routes in the pelvic and para-aortic regions. Inguinal lymph nodes are not a common site for ovarian cancer metastasis. The lymphatic drainage of the ovaries primarily goes to the pelvic lymph nodes, then to the para-aortic lymph nodes. Inguinal lymph nodes are involved in the lymphatic drainage of the lower limbs and external genitalia.
