OP09.01: The cervical strain elastography in predicting the risk of spontaneous preterm birth

Abstract

Short oral presentation abstractswere to determine rates of success, predictors for success and explore complications. Methods: Retrospective analysis of pathology reports and patients charts in 64 consecutive patients in the period from October 2014-January 2018 in a gynecological oncology centre. A 18-gauge trucut needle was used in all cases. Rates of success and complications were calculated. Gold standard was final histology from surgery, except in cases of ovarian cancer, where chemotherapy was initiated after positive histology. Two patients had no gold standard and the biopsies were considered insufficient. Results: 64 patients had a total of 67 biopsies. Indications for biopsies were suspicion of ovarian cancer (n=39), uterine sarcoma (n=14), metastasis from gastrointestinal cancer (n=5), peritoneal cancer (n=4) and other pelvic cancer (n=2). Age range 22-90, median 58. In 80 % of the patients (51/64) the biopsies were sufficient for diagnosis. The failures were not operator or time associated. Success rate was related to indication, among patients with suspicion of ovarian cancer the success rate was 85% (33/49), but in sarcoma the success rate was 65% (9/14) (p=0.0011 (Fisher's exact test)). Recurrent biopsies in three patients with primarily insufficient biopsy led only to diagnosis in one. One patient, 1.6% (1/64) had a pulmonary embolism after the anticoagulant therapy was paused in accordance with National guidelines. Conclusions: Transvaginal ultrasound-guided trucut biopsies were successful in 80% of patients. The success rate was related to indication with a significant higher success rate in ovarian cancer 83% compared to 60% in uterine sarcoma. The complication rate was 1.6%.
