Prognostic significance of number of nodes removed in patients with node-negative early cervical cancer

摘要

Aim: The aimof our study was to assess the levels of human epididymis protein 4 (HE4) with the common tumor marker carbohydrate antigen 125 (CA125) in the diagnosis and monitoring of therapy for primary fallopian tube carcinoma (PFTC). Methods: SerumHE4 and CA125 levels from 82 PFTC patients and 154 patients with benign pelvic masses as the control were measured by Roche electrochemiluminescent immunoassay. HE4 determinations for surgery response and recurrence monitoring were assessed in PFTC patients. Results: Serum HE4 and CA125 concentrations were significantly higher in PFTC patients compared with those seen in patients with benign pelvic masses (P < 0.001). Compared with CA125, HE4 had higher specificity, but lower sensitivity whether at early or advanced stage, and the combination ofHE4 + CA125 led to higher sensitivity and specificity. HE4 + CA125 performed significantly better than CA125 or HE4 alone in early stage patients. In early stage the sensitivity was 35.7% forHE4 and 64.3% for CA125, while sensitivity for the combination ofHE4 and CA125 could reach 71.4%. Furthermore, the two markers were associatedwith the progression and histology of PFTC. SerumHE4 level was closely correlated with surgical therapy. PFTC patients displayed a greater decline in the level of HE4 compared with CA125 (76.4% vs 55.7%). Combined with CA125, HE4 elevation better predicted recurrence in PFTC patients. Conclusions: This study indicated that serum HE4 levels are closely associated with PFTC and the outcome of surgical therapy and recurrence in Chinese patients.
