“…Regarding the size of tumor it was observed that 1 to 3 cm (7.1%), 3.1 to 5 cm (14.3%), 5.1 to 10 cm (60.7%) and more than 10 cm (17.9%) were commonly detected size of the tumor size among the patients. Kawai et al 21 and Hamper et al 22 had almost same observation.…”

Background: Ovarian cancer is one of the leading causes of morbidity and mortality. Objectives: The purpose of the present study was to find out clinic-demographic and histopathological variants of ovarian cancer. Methodology: This cross-sectional study was conducted in the Department of Obstetrics and Gynaecology at four largest tertiary care Hospitals in Dhaka city from January 2008 to December 2009. Clinically diagnosed and histopathologically confirmed ovarian cancer patients were included in this study. Result: Histopathological confirmed 28 patients of ovarian cancer were enrolled in this study. The mean age (±SD) was 40.6 (±12.5) years (Range 13 to 63 years). Lower abdominal lump (71.4%) was the most common symptoms. Family history (14.0%) and multiparty (53.0%) were also associated with ovarian cancer. Among 28 malignant tumors cases serious cyst adenocarcinoma (57.1%) was the most common followed by mucinous cyst adenocarcinoma (17.9%), dysgerminoma (7.1%), adenocarcinoma of ovary (7.1%), ovarian choriocarcinoma (3.6%) and endometriod adeno carcinoma (3.6%). High serum CA125 was found in 78.0% cases. Conclusion: Lower abdominal lump, multiparity and positive family history are the common clinical findings of ovarian cancer. Both serous and mucinous cyst adenocarcinoma are the common varient of ovarian cancer found in this study. [J Shaheed Suhrawardy Med Coll, 2013;5(1):3-6]

“…It is factually correct that low impedance to blood flow with high velocity is suggestive of malignancy, whereas moderate-tohigh impedance to blood flow is correlated to benign tumors. Resistive indices less than 0.4-0.8 [3,5] and pulsatility indexes less than 1.0 are generally considered to be suspicious for malignancy [3][4][5][6]. In the present study, PI \ 0.8 and RI \ 0.6 were considered for analysis.…”

Aims The aim of the present study was to prove the efficiency of Color Doppler and Spectral Doppler in evaluation and characterization of the ovarian neoplasm. Materials and Methods In total, 104 patients with adnexal masses were examined sonographically to evaluate for morphologic characteristics, as well as pulsatility indices (PI), and resistance indices (RI) over a period of 2 years, of which 20 were excluded as the masses were not finally proven to be adnexal, and thus 84 patients with ovarian neoplasm were retained as the study subjects. The final diagnosis was based on histopathologic confirmation. Result Out of 84 cases, 44 were benign and 40 were malignant. Color Doppler showed vascularity in 97.5 % of malignant tumors in contrast to only 68.1 % of benign tumors. The present study showed that, 87.5 % of malignant tumors had PI less than 0.8 in contrast to only 4.54 % of benign tumors. Similarly, 82.5 % of malignant tumors had RI less than 0.6 in contrast to only 6.81 % of benign tumors. Conclusion Multiparameter analysis utilizing B-mode USG along with Color Doppler and Spectral Doppler is the mainstay in diagnosis of patients with ovarian tumors. A good specificity (84.1 %) and sensitivity (97.5 %) with PI and RI values of \1.0 and \0.6, respectively, was achieved with the present study which is highly significant in differentiating between malignant and benign ovarian tumours.

“…The results have been controversial. Some authors have found this technique useful 2 -10 , whereas others have not [11][12][13][14][15][16][17] . Some factors put forward to explain these conflicting results include differences in sonographers' experience, different sensitivity in ultrasound machines and the lack of standarization of Doppler measurements 27 .…”
