ABSTRACT
Low-grade stage I endometrioid endometrial carcinomas should have an excellent prognosis, but a small subset of these cancers can relapse. The search for putative immunohistochemical prognostic markers for relapse in low-risk/low-grade endometrioid endometrial cancers remains open. Among the candidate molecules that may implicate the roles of immunohistochemical risk markers, we focused our attention on human epididymis protein 4 (HE4) after a review of the literature. Few authors have devoted themselves to this topic, and none have found a correlation between the tissue expression of HE4 and the molecular classification of endometrial cancer. Five different variants of HE4 mRNA and multiple protein isoforms of HE4 were identified many years ago, but current HE4 assays only measure the total HE4 expression and do not distinguish the different proteins encoded by different mRNA variants. It is important to have an approach to distinguish specific variants in the future.

OBJECTIVE: To evaluate the long-term objective and subjective outcomes to build recurrence-free survival curves after mesh-free uterosacral ligament suspension and to evaluate the long-term impact of prognostic factors on outcome measures. METHODS: A retrospective study analyzed 5-year follow-up after repair of primary prolapse through high uterosacral ligament suspension. Bulging symptoms and post-operative prolapse stage II or above were considered subjective and objective recurrences, respectively. The cumulative proportion of relapse-free patients in time was analyzed by Kaplan-Meier curves. RESULTS: A total of 353 women were analyzed. Five-year recurrence rates were 15.0% for objective recurrence, 13.0% for subjective recurrence, and 4.0% for the combined objective and subjective recurrences. Premenopausal status was shown to be a risk factor for anatomic (P=0.022), symptomatic (P=0.001), and combined (P=0.047) recurrence. Conversely, anterior repair was shown to be a protective factor for symptomatic (P=0.012) and combined (P=0.002) recurrence. Most of the recurrences occurred within 2 years after surgery. CONCLUSION: Long-term outcomes after high uterosacral ligament suspension were satisfactory. Premenopausal status and lack of anterior repair represented risk factors for recurrence in the long term.
