Ans: B (Stage 3b) Ref: Slum 's Textbook of Gynecolgy pg 4T2Explanation:CARCINOMA CERVIX STAGINGStage IStage I is carcinoma strictly confined to the cervix.The diagnosis of both Stages 1A1 and IA2 should be based on microscopic examination of removed tissue, preferably a cone, which must include the entire lesion.Stage IA: Invasive cancer identified only microscopically. Invasion is limited to measured stromal invasion with a maximum depth of 5 mm and no wider than 7 mm.Stage IA1: Stage IA1: Measured invasion of the stroma no greater than 3 mm in depth and no wider than 7 mm diameter.Stage IA2: Stage IA2: Measured invasion of stroma greater than 3 mm but no greater than 5 mm in depth and no wider than 7 mm in diameter.Stage IB: Stage IB: Clinical lesions confined to the cervix or precltnical lesions greater than Stage IA. All gross lesions even with superficial invasion are Stage IB cancers.Stage Hit: Stage IB 1: Clinical lesions no greater than 4 cm in size.Stage IB2: Stage IB2: Clinical lesions greater than 4 cm in size.Stage IIStage II is carcinoma that extends beyond the cervix, but does not extend into the pelvic wall.The carcinoma involves the vagina, but not as far as the lower third.Stage IIA: No obvious parametrial involvement. Involvement of up to the upper two- thirds of the vagina.
