Pathological assessment
The pathology results were reviewed by two experienced pathologists from
each department. According to the WHO classification of tumors of female
reproductive organs, the NECC has been classified into four histological
subtypes: small cell (SCNEC), large cell (LCNEC), and carcinoid (typical
and atypical) [9]. Pathology results demonstrated
that all patients had high-grade NECC (SCNEC and LCNEC).
