Ovarian masses: changing clinico histopathological trends

Clinicopathological analysis of giant ovarian tumors

Objective

This study aims to analyze giant ovarian tumors' clinical and pathological characteristics.

Material and Methods

This was an analytical observational study. Medical records of all patients with giant ovarian tumors who underwent surgery between January 2020 and June 2022 at Dr. Soetomo Academic Hospital, Surabaya, Indonesia, were analyzed.

Results

We analyzed 63 patients with ovarian tumors measuring > 20 cm who underwent surgery at Dr. Soetomo Academic Hospital, Surabaya, Indonesia. The mean tumor size was 25.9 cm (largest size was 41 cm). There was no significant difference in tumor size between benign and malignant giant ovarian tumors (p = 0.261). Based on histopathological results, 66.67 % of giant ovarian tumors were malignant, 26.98 % were benign, and 6.35 % were borderline. Among the malignant tumors, the epithelial type accounted for 69 % of cases. Most giant ovarian tumors originated in the left adnexa (68.25 %). There was no significant difference in patient age (p = 0.511), tumor size (p = 0.168), malignancy (p = 0.303), and histopathological type (p = 0.232) regardless of adnexal side. CA125 levels did not differ significantly between malignant and benign giant ovarian tumors (p = 0.604). There was no correlation between malignant ovarian tumor size and CA125 levels, while there was a significant difference between CA125 levels and the adnexal side (p = 0.010).

Conclusions

Most giant ovarian tumors were malignant, diagnosed at an early stage, and predominantly epithelial type. CA125 levels did not correlate with the size of malignant ovarian tumors. Most giant ovarian tumors originate in the left adnexa.

Bilateral Ovarian Torsion Due to a Giant Mucinous Cystadenoma, Contralateral Mature Teratoma, and Paratubal Cyst in a Young Adult

Giant ovarian cysts (>10 cm) are rare due to the widespread use of routine imaging. However, in the absence of compressive symptoms, giant cysts remain a diagnostic challenge, especially in patients with larger body habitus. Complications of benign ovarian cysts are infrequent but can include torsion of the adnexa. Bilateral torsion is a rare emergency that can threaten a patient's future fertility. In this case, we report on a 24-year-old female with bilateral torsion due to a triad of adnexal masses including a 30 cm mucinous cystadenoma, a 10 cm mature teratoma, and an 8 cm paratubal cyst. Controlled fluid aspiration was performed prior to en bloc resection of the cystadenoma due to the emergent nature of the case and lack of malignant features.

Clinical Performance of a Multivariate Index Assay in Detecting Early-Stage Ovarian Cancer in Filipino Women

This study evaluated the clinical performance and overall utility of a multivariate index assay in detecting early-stage ovarian cancer in a Filipino population. This is a prospective cohort study among Filipino women undergoing assessment for an ovarian mass in a tertiary center. Patients diagnosed with early-stage ovarian cancer and who underwent a physical examination before level III specialist ultrasonographic and Doppler evaluation, multivariate index assay (MIA2G), and surgery for an adnexal mass were included in this study. Ovarian tumors were classified as high-risk for malignancy based on the IOTA-LR2 score. The ovarian imaging and biomarker results were correlated with the reference standard: surgico-pathologic findings. The MIA2G exhibited the best overall performance among individual classifiers with a sensitivity of 91.7% and NPV of 84.7%, with a concomitant higher sensitivity in early-stage disease, whether as an individual classifier (93.5%) or in serial combination with ultrasound (85.5%). The performance of biomarkers (specificity, positive predictive values, and AUROC) such as MIA2G and CA-125 significantly improved when combined with an ultrasound risk scoring approach (p < 0.01). MIA2G showed a higher sensitivity for detecting lesions among EOC and late-stage ovarian cancers than otherwise. The application of biomarkers for evaluating ovarian masses in our local setting is secondary to ultrasound but adopting multivariate index assays rather than CA-125 would increase the detection of early-stage ovarian cancers regardless of menopausal status. This is most relevant in areas where level III sonographers or gynecologic oncologists are limited and preoperative referrals to these specialists can improve the survival of our patients.

A giant ovarian mucinous tumor in a 58-year-old postmenopausal patient with persistent abdominal pain and high serum levels of CA 19-9

Ovarian cancer is the seventh most commonly diagnosed cancer among women in the world and epithelial ovarian cancer is the most predominant pathologic subtype. Tumor markers are widely used in clinical practice to determine therapeutic efficacy, to detect recurrence and to predict prognosis in known cancers. CA-19-9 antigen is mainly elevated in cases of gastrointestinal tract malignancy, including of the pancreas, colorectum, and biliary tract. However, CA 19-9 antigen can also be elevated in ovarian mucinous neoplasms. We report herein the case of a 58-year-old woman who presented with an abnormally high level of CA 19-9 antigen associated with ovarian mucinous borderline tumor.

Clinicopathological profile of adnexal masses presenting to a tertiary-care hospital in Bhutan

CONTEXT

Adnexal masses of ovarian origin are of growing concern due to high fatality associated with ovarian malignancy because they are diagnosed at advanced stage due to vague symptoms and absence of recommended screening tests.

AIMS

The aim was to study the prevalence of histopathologic types of adnexal masses in different age groups and to analyze the accuracy of preoperative evaluation in diagnosing ovarian malignancy.

SETTINGS AND DESIGN

This was a cross-sectional study carried out in the Department of Obstetrics and Gynecology of a tertiary care hospital in Bhutan with gynecologic-oncology services, from January to December 2017.

SUBJECTS AND METHODS

Women presenting with adnexal mass were evaluated and those meeting criteria were enrolled. They were evaluated preoperatively with complete history, examination, ultrasound, and tumor markers. Risk of malignancy index (RMI) was calculated for all patients. Following surgery, histopathology results were compared with preoperative evaluation.

STATISTICAL ANALYSIS USED

Chi-square test, t-test, Cohen's Kappa, and receiver operating characteristic curve analysis were used for statistical analysis.

RESULTS

Of 165 patients evaluated, 127 fulfilling criteria were enrolled. Adnexal masses of ovarian origin were most common (n = 102, 80.3%), of which 12.7% were malignant. Epithelial ovarian malignancy was the most common malignant ovarian tumor, serous cystadenocarcinoma being the most common. Malignancy was significantly more in older, postmenopausal women with high RMI. Seven out of 11 women with high RMI were diagnosed in Stage 3 or 4. RMI score at cutoff of 200 was 54.6% sensitive and 85.7% specific.

CONCLUSIONS

Adnexal mass of ovarian origin was the most common. Malignancy was significantly more in older, postmenopausal women with high RMI. RMI showed moderate correlation in diagnosing epithelial ovarian malignancies.

Pattern of benign ovarian cysts in Qatari women

Objective: To study the age distribution, histopathological types, lateral distribution and surgical interventions performed for benign ovarian cysts in Qatari women undergoing surgical intervention for an ovarian cyst. Design: A retrospective descriptive study. Setting: Obstetrics and Gynecology Department, Al-Ahli Hospital, Doha, Qatar. Patients and methods: Data were collected retrospectively from clinical records of Qatari women who underwent surgical intervention from 1 January 2013 to 31 December 2015 at Al-Ahli Hospital for an ovarian or paraovarian cyst. The age distribution, frequencies and percentages were calculated for each type of ovarian cyst and the side of the ovary involved was recorded. Results were statistically analysed by IBM SPSS, version 23. Results: A total of 81 women had an ovarian or paraovarian cyst. Age ranged from 16 to 58 years. The maximum number of women were in the 21–30-year-old age group. Benign epithelial cysts were found to be most common (32; 39.5%), of which the majority were for endometriotic cysts (15; 18.5%), serous cystadenoma (13; 16%) and mucinous cystadenoma (4; 4.9%). This was followed by physiological cysts (26; 32.1%), which included corpus luteal cysts (15; 18.5%) and simple follicular cysts (11; 13.6%). The other categories of ovarian tumours were for mature cystic teratoma (14; 17.3%), benign sex cord–stromal tumours (1; 1.2%) which included stromal cell tumours (1; 1.2%), borderline ovarian tumour (1; 1.2%) and paraovarian cysts (7; 8.6%). There was bilateral ovarian involvement in 9 cases (11.1%) and unilateral involvement in 72 (88.9%). The right ovary was involved in more cases (39; 48.1%), than for the left ovary (33; 40.7%). Conclusion: Benign epithelial tumours were found to be the most common type of ovarian tumour in Qatari women. Endometriotic cysts followed by serous cystadenomas were the most common types of benign epithelial tumours. The right ovary was found to be involved in more cases than the left ovary.
