2 years study on p53 expression on serous and mucinous tumors of ovary
Journal Title: International Archives of Integrated Medicine - Year 2016, Vol 3, Issue 7
Abstract
Background: Epithelial ovarian carcinoma is worldwide the sixth most common female cancer. This malignancy carries the highest mortality among all gynecological cancers. Aim and objectives: To perform and interpret p53 immunostaining on the diagnosed serous and mucinous malignant surface epithelial ovarian tumors and to correlate expression of p53 with histological type of malignancy. Materials and methods: 2 year prospective study was done i.e. from October 2011 to September 2013 on “p53 interpretation on surface epithelial ovarian tumors” in MGM Hospital, Warangal. All the ovarian surface epithelial tumor specimens, received in the pathology department during this period were considered. Results: A total of 120 cases were studied, out of which benign tumors were the most common (64.2%), followed by malignancy (25.8 %) and 12 cases (10%) of borderline malignancy. Most of the benign tumors were unilateral, the cases which showed bilateral involvement were mostly malignant. The maximum number of cases in the present study was seen in the age group of 31-60 years. The youngest patient was 16 years old and the oldest was 68 years old. Serous cyst adenoma was the most common neoplasm found and accounted for 53 cases (44.2%) , followed by mucinous cystadenoma, which accounted for 21 cases (17.5%). 9 cases of serous cystadenofibroma (7.5%), 3 borderline serous tumors (2.5%) and 11 serous cystadenocarcinoma (9.1%) were found in the present study. Out of the 44 mucinous tumors, 21 were benign (17.5%), 3 were of borderline malignancy (2.5%) and 20 were malignant (16.7%). One case of mucinous cystadenocarcinoma was found to be associated with adenocarcinoma of ascending colon. One case of benign Brenner tumour was also found in the present study. Conclusion: The rate of p53 abnormalities varies with histologic type, grade and stage of the tumor. P53 expression was more in malignant serous tumors as compared to the malignant mucinous tumors.
