Ultrasonographic Findings Indirectly Predicting Parametrial Involvement in Patients with Deep Endometriosis: The ULTRA-PARAMETRENDO I Study

STUDY OBJECTIVE

To evaluate ultrasonographic findings as a first-line imaging tool to indirectly predict the presence of parametrial endometriosis (PE) in women with suspected deep endometriosis (DE) undergoing surgery.

DESIGN

Retrospective analysis of a prospectively collected database (ULTRA-PARAMETRENDO I study; NCT05239871).

SETTING

Referral center for DE.

PATIENTS

Consecutive patients undergoing laparoscopic surgery for DE.

INTERVENTIONS

Preoperative transvaginal ultrasonography was done according to the International Deep Endometriosis Analysis consensus statement. A stepwise forward regression analysis was performed considering the simultaneous presence of DE nodules and the following ultrasonographic indirect signs of DE: diffuse adenomyosis, endometriomas, ovary fixed to the lateral pelvic wall or the uterine wall, absence of anterior/posterior sliding sign, and hydronephrosis. The gold standard for the presence of PE was surgery with histologic confirmation.

MEASUREMENTS AND MAIN RESULTS

Of 1079 patients, 212 had a surgical diagnosis of PE (left: 18.5%; right: 17.0%; bilateral: 15.9%). The obtained prediction model (χ² = 222.530; p <.001) for PE included, as independent indirect DE signs presence of hydronephrosis (odds ratio [OR] = 14.5; p = .002), complete absence of posterior sliding sign (OR = 3.3; p <.001), presence of multiple endometriomas per ovary (OR = 3.0; p = .001), and ovary fixation to the uterine wall (OR = 2.4; p <.001); as independent concomitant DE nodules, presence of uterosacral nodules with the largest diameter >10 mm (OR = 3.2; p <.001), presence of rectal endometriosis with the largest diameter >25 mm (OR = 2.3; p = .004), and rectovaginal septum infiltration (OR = 2.3; p = .003). The optimal diagnostic balance was obtained considering at least 2 concomitant DE nodules and at least 1 indirect DE sign (area under the curve 0.75; 95% confidence interval, 0.72-0.79).

CONCLUSION

Specific indirect ultrasonographic findings should raise suspicion of PE in women undergoing preoperative assessment for DE. The suspicion of parametrial invasion may be critical to address patients to expert leading centers, where proper diagnosis and surgical treatment for PE can be performed.

A prospective multicentric study of risk-reducing salpingo-oophorectomy in BRCA mutation patients

BACKGROUND AND AIM OF THE WORK

BRCA1/2 are tumour-suppressor genes involved in DNA homologous recombination and ovarian cancer development.  The study evaluated the risk of tumor cancer in women presenting the BRCA mutations.

METHODS

Risk-reducing surgery (RRS) was performed in 100 patients carrying BRCA1 (aged between 30-73 years, median age was 51 years) and BRCA 2 mutation (aged between 36-70 years, median age was 53 years). Fifty-eight patients had previous history of breast cancer.

RESULTS

Between the 100 patients, 82 women underwent risk-reducing salpingo-oophorectomy (RRSO) through a laparoscopic minimally invasive approach, 7 (7 %) underwent laparoscopic RRSO and contextual hysterectomy, 1 woman (1 %) underwent RRSO through a laparotomic approach and 10 women (10 %) laparotomic RRSO and hysterectomy. During 5 (5 %) laparoscopic RRSO, prophylactic bilateral mastectomy was also performed. Early and late complication occurred in 3 patients (3 %). Two patients (2 %) were found to have occult Serous Tubal Intraepithelial Carcinoma (STIC) and three patients (3 %) occult cancer.

CONCLUSIONS

RRSO is safe and feasible in BRCA mutation carriers. The procedure is effective for genetic prevention of ovarian cancer.
