Abstract:
Objective:To evaluate the pathologic findings from biopsy samples to predict the status of nodal metastasis for patients with usual cervical adenocarcinoma.Methods:The 32-pair samples of cervical adenocarcinoma specimens (32 cervical biopsies and 32 hysterectomies with staging) from 2013 to 2019 were selected for retrospective study in Shanghai first Maternal and infant Health Care Hospital Affiliated to Tongji University. The correlation between histopathologic features including necrotic tumor debris (NTD), nuclear grade, mitotic count and pattern-based classification system and the status of lymph node metastasis was evaluated.Results:Tumor invasive patterns of cervical adenocarcinoma, as described previously, could be discerned in hysterectomy/staging specimens, but not in cervical biopsies. Because the biopsy tissues were small, only 14(14/32, 43.8%) cases could be classified according to pattern of invasion, and the concordance rate with resected specimens was 37.5%. NTD (9/19) and grade 3 nuclei (11/19) were positively correlated with invasive pattern C and nodal metastases ( P<0.05). Moreover, when NTD and (or) nuclear grade were evaluated at the same time, the sensitivity for type C infiltration was higher. Conclusions:Evaluation of NTD and nuclear grade in biopsies for cervical adenocarcinoma provides good predictive value for lymph node metastasis. It is helpful for patient stratification and management andto avoid unnecessary staging procedures. However, multicenter studies and prospective clinical trials are necessary to confirm the findings before clinical application can be considered.
