Multivariate Discriminant Analysis on Differentiating Sheep Breeds Based on Live Body and Carcass Measurements

The objective of this study was to investigate the pathological diagnostic efficacy of applying cytological smears (CytS) combined with frozen sections (FroS) in patients with ovarian tumour (OT), and to study the relevant factors affecting the pathological diagnostic efficacy of CytS combined with FroS.A total of 106 patients admitted for OT surgery from May 2022 to May 2023 were selected as study subjects using simple random sampling method.FroS, CytS and paraffin sections were performed on all tumour tissue specimens during and after surgery.In the univariate analysis, tumour diameter and whether metastasis was a relevant factor affecting the diagnostic efficacy of cytology smear combined with frozen section, and in the multivariate logistic regression analysis, tumour diameter and whether metastasis was an independent risk factor affecting the pathological diagnostic efficacy of cytology smear combined with frozen section.The application value of cytology smear combined with frozen section diagnosis in OT patients is high, and its diagnostic effect is good.In order to ensure the accuracy of the diagnostic results of cytology smear combined with frozen section diagnostic results, the size of the diameter of the patient's tumour and whether metastasis occurs should be taken into account during the actual test, so as to improve the diagnostic accuracy of the case and provide a strong basis for clinical treatment.
