Does change in endometrial carcinoma FIGO staging (2018 to 2023) matters?

Abstract Introduction/Objective Endometrial Carcinoma (EC) is the sixth most common diagnosed cancer in women. Cancer related to corpus uteri are often diagnosed after menopause. TNM classification and FIGO staging system is used for staging of EC. College of American Pathologists (CAP) has been using FIGO staging system 2018 until new FIGO staging 2023 was published on June 20th 2023. We aim to identify if the new 2023 FIGO staging will change the previously assigned staging as per 2018 FIGO staging system of the endometrial carcinoma and if this change will help the physician to reevaluate the patient management. Methods/Case Report This is a retrospective cohort study. Total 205 cases were recruited from June 2022 till October 2023 at Danbury Hospital. All the patients of 18 years and above were selected for the study and were treated with hysterectomy for endometrial carcinoma and were reported to have FIGO staging as per 2018 CAP cancer protocol. Sixty three (63) participants were selected for the study. Exclusion criteria includes the cases diagnosed as endometrial carcinoma on biopsy, curettage, and patients who did not follow up for treatment. The data search was done on variables required to evaluate the FIGO staging for 2018 and 2023. Results (if a Case Study enter NA) Out of 63 patients, 55 cases were reported as per FIGO stage 2018 and eight cases were evaluated on TNM classification only. The staging did not change for forty nine (49/63) cases. However, six cases (6/63) had a change in staging based on the criteria out of which four cases (4/6) had an upstage and two cases (2/6) had a downstage. Conclusion Staging has a critical role in management of the patient. The updated FIGO staging includes multiple variables (including molecular) to improve the patient care who are diagnosed with endometrial carcinoma. Identifying the appropriate updated staging can be beneficial for oncologist to decide the treatment recommendation in the future.
