Materials And Methods- Study based on proper clinical examination, radiological investigation, histopathological diagnosis and hematological investigations and Measurement of serum CA-125 and HE4 will be carried out by ELISA method. Results- out of 50 neoplastic lesions 31 cases are benign tumours, 02Borderline and 17 cases are malignant. Conclusion-We concluded High ROMA Index Value shows malignancy. Low value of ROMA index cases are benign so that ROMA Index is helpful to differentiate in benign and malignant lesion preoperatively |
