The aim of this RCT of study is to compare the standard TLH with adnexal preservation with TLH plus prophylactic bilateral salpingectomy (PBS) in terms of ovarian reserve and surgical outcomes

Ovarian cancer accounts for 3% of all female cancers and represents the fifth leading cause of cancer death in the Western world (1). In 90% of cases, these are epithelial ovarian cancers (2).

Because of the biological aggressiveness of this tumor and nonspecific symptoms, that causes a diagnosis at an advanced stage in 75% of cases, ovarian cancer is the gynecological cancer with the highest mortality rate (3).

To date, an effective screening strategy to the early diagnosis of ovarian cancer doesn't exist, so the prophylactic adnexectomy is the only available tool to reduce the incidence and the mortality rate, even if the role of this surgical strategy is controversial, especially in premenopausal women (4). In fact, the American College of Obstetricians and Gynaecologists (ACOG) guidelines recommend the ovarian preservation in premenopausal women with no family history or other risk factors for ovarian cancer (5).

Some clinical studies have shown that the prophylactic adnexectomy and the consequent surgical menopause increase significantly the long term risk of cardiovascular and psychosexual diseases. (6-8). In particular, a case-control study done in a population of 29,380 women subjected to hysterectomy with and without adnexectomy, showed an increased risk of total mortality ( HRs 1.12 95 % CI 1:03 to 1:21 ), lethal and non- lethal cardiovascular disease ( HRs 1.17 95 % CI 1:02 to 1:35 ) and stroke ( HRs 1.14 95 % CI 0.98-1.33 ) (9) . In this population of women subjected to salpingectomy, the surgery wasn't able to lead to an improvement in general survival (10).

Considering the new histopathological classification of the epithelial ovarian cancer, proposed by Kurman (11) and based on new acquisitions about the pathogenesis and the origin of these tumors, it is possible to conceive a new preventive strategy associated with a less morbidity.

In fact, the carcinogenesis model proposed by Kurman, provides for the classification of the most important histological types of epithelial tumors into two types, diversified according to clinico-pathological and genetic features.

The type I is composed of low-grade serous, low-grade endometrioid, clear cell and mucinous carcinomas, whose the ovarian borderline tumors and endometriosis represent the pre-neoplastic lesions. Conversely, the II type includes high-grade endometrioid carcinomas, carcinosarcomas and undifferentiated carcinomas and, more frequently, high-grade serous carcinomas, whose preneoplastic lesion, now, seems to be represented by the serous tubal intraepithelial carcinoma (STIC).

Plenty of evidence, to support the correlation between the epithelial ovarian cancer and the STIC, has been obtained by immunohistochemical and molecular genetics investigations (11). However, from a clinical point of view, this association has been demonstrated only by a study on 55 patients affected by a high-grade serous carcinoma, whose results have shown an involvement in the endosalpinx in 70% of cases and the presence of STIC in about 50% of cases (12).

Some studies, performed on BRCA1 / 2 populations, showed the presence of strongly sites reactive to p53, defined "p53 signature", in the distal tube (13). These sites seem to be more frequent and characteristically multifocal in those tubes with concomitant STIC (14). The finding of "p53 signature" may, therefore, identify an early clonal expansion of the neoplastic proliferation.

This new theory has given the opportunity to prevent this devastating type of cancer by the addition of the prophylactic bilateral salpingectomy (PBS, with the only removal of the tube and the preservation of the ovaries) in all surgical procedures performed in those women with benign diseases once they have accomplished their reproductive desire. The PBS, in place of the current standard procedure (bilateral salpingo-oophorectomy) could reduce the risk of cancer, improving at the same time the quality of life and reducing the risk of premature death due to cardiovascular disease, seen in women subjected to salpingo-oophorectomy before the onset of natural menopause.

Our preliminary data (17) show that, if the bilateral salpingectomy is performed with great care, no patient has negative effects in terms of ovarian function. In addition, in our experience, no perioperative complication is attributable to salpingectomy alone. Despite the retrospective design of our first study, according to the post hoc analysis, these data have shown a significant statistical reliability.

However, prospective data on the effetc of PBS in patients submitted to TLH are still needed

Women who have had one or both fallopian tube(s) removed as method of ovarian cancer prevention.

Elizabeth Swisher, MD

The purpose of this study is to better understand why women choose to have their fallopian tubes removed as a method for ovarian cancer prevention. This will be done through a paper questionnaire and phone interviews. The investigators hope to gain information that will allow us to better counsel women about ovarian cancer prevention.

Women will be found eligible for this study after an eligibility questionnaire given over the phone. If one is found eligible, she will be sent a consent and paper survey to fill out and send back to the research coordinator. Once that is completed, she will be given a phone interview in order answer additional questions of interest. Lastly, the study participant will be contacted once a year over the phone to obtain follow-up information.

However, the most recent acquisitions assume that also the tissue surrounding the tube seems to give rise to neoplastic sites, so it is conceivable that a greater oncological radicality can be obtained removing the tube and the adjacent structures (mesosalpinx). Now it remains to prove if also the radical technique of prophylactic salpingectomy causes no functional damage to the ovary.

While ASA is not a cancer medication, research suggests that taking ASA reduces the probability of getting many types of cancer because of its anti-inflammatory action. Inflammation in the ovaries during ovulation is thought to contribute to the development of ovarian cancer, and, because ASA is an anti-inflammatory medication, it may help to prevent it.

The standard or usual treatment for women with a high risk gene mutation, BRCA1 or BRCA2, is to have risk-reducing surgery to remove the fallopian tubes and ovaries (bilateral salpingo-oophorectomy or bilateral salpingectomy inclusive of fimbria) after they have decided not to have more children naturally.

Acetylsalicylic Acid (ASA) is a safe, well tolerated drug taken by mouth. ASA has been available for over 100 years and has been used mainly to relieve fever and pain, but also as an anti-inflammatory medication in order to reduce inflammation (swelling).
