Phenotypic Spectrum of CTCs in Tumors of the Female Reproductive System
Breast CancerOvarian Cancer1 moreThe study evaluates the level and molecular profiles of different CTC populations as markers for predicting the risk of developing hematogenous metastases and the effectiveness of treatment in patients with tumors of the female reproductive system (breast cancer, endometrial cancer, and ovarian cancer). The primary objective are: To assess the presence and number of different populations of CTCs at different time points (before biopsy, before surgery, and after surgery). To assess the relationships of different CTCs populations prior to treatment initiation with the effects of neoadjuvant chemotherapy and the risks of recurrence and metastases. To assess the molecular profiles of different CTCs populations in the blood and in ascitic fluid. The secondary objective is to compare the multicolor flow cytometry results with data of ultrasound, CT and/or MRI, serum tumor markers, and immunohistochemical studies in patients with breast cancer, endometrial cancer and ovarian cancer
Endometrial Changes in Breast Cancer Women With or Without Hormonal Therapies
Breast CancerEndometrial CancerA history of breast cancer is a risk factor for the development of endometrial pathologies, such as typical and atypical glandular hyperplasia, endometrial polyps, uterine fibroids, endometrial adenocarcinoma and uterine sarcoma, probably due to some common risk factors (eg. obesity, nulliparity). Even if ethiopathogenesis for breast cancer and endometrial pathologies is not well established, both genetic factors and hyperestrogenic state may be play a pivotal role for their development. Indeed, relative hyperestrogenism is also the main target for the treatment of breast cancer. Currently used therapies for this purpose are selective estrogen receptor (ER) modulators (SERMs), such as Tamoxifen (TAM), and third generation non-steroidal aromatase inhibitors (AIs), such as letrozole and anastrozole. TAM has both agonist and antagonist properties, depending upon the individual target organ and circulating levels of serum estrogens: on the one hand, it blocks estrogen stimulation in breast tissue; on the other hand, TAM shows an ER agonist activity in the endometrium that is able to stimulate proliferation and, in some cases, it causes an increased risk of uterine pathologies. Women with hormone-dependent breast cancer have to use TAM for five to ten years. Many reports suggest that the risk of uterine pathologies increases with the time of administration. Considering these elements, the primary aim of this study will be to investigate the incidence of endometrial pathologies, especially of endometrial cancer, in different groups of breast cancer women undergoing diagnostic hysteroscopy.
Implementation of a Rapid Recovery Program in Gynecologic Oncology Surgery: A Pilot Study
Cervical CancerUterine Endometrial Cancer1 moreOver 600,000 hysterectomies are performed annually in the United States. Despite increasing use of less invasive approaches, the majority of hysterectomies are still performed via traditional laparotomy, which can be associated with generally slower recovery and longer lengths of post-operative hospitalization. Rapid Recovery Protocols (RRP) seek to optimize post-surgical morbidity outcomes by returning a patient to normal physiology as quickly as possible following surgery.
Linking Obesity and Estrogen-responsive Genes in Endometrial Cancer
Endometrial CancerThe objective is to develop an organotypic model to assess the effects of obesity on the expression and methylation status of estrogen-responsive genes in endometrial cancer. Omental fat samples will be removed from participants during surgery and these fat samples will be used in laboratory analyses.
Lymphedema in Endometrial Cancer
Lower Extremity LymphedemaEndometrial CancerObjectives: (1) To determine the incidence of lower-extremity lymphedema after staging surgery for endometrial cancer; (2) to describe lymphedema-related morbidity after staging surgery for endometrial cancer and (3) to evaluate pre- and post-operative quality of life in women with endometrial cancer who undergo staging surgery. Data analysis and risk/safety issues: The proposed study will consist of a convenience sample of women who undergo minimally invasive surgery for endometrial cancer over a 1 year period. The investigators anticipate enrollment of 75 to 100 women. Frequency tables and difference with its 95% exact confidence intervals between pre-and post-operative lower extremity lymphedema measurements and quality of life questionnaires will be estimated.
Comparing Robotics and Laparoscopy With Laparotomy/Open Surgery for Endometrial Cancer
Cancer of the EndometriumThe use of robotic surgery in the management of gynecologic cancers has increased exponentially in the United States since the implementation of technology in 2005. In Canada, access to the system is limited because of a lack of government funding. The government has been reluctant to fund this technology because robust data, on the true impact to patient care, is lacking. This project will prospectively examine outcomes of women, with early stage endometrial cancer, treated surgically. Open surgery will be compared to minimally invasive surgery (MIS) which will include conventional laparoscopy and robotic surgery. The data collected will include detailed assessment of surgical data, peri-operative events, quality of life analysis, health economic evaluation and evaluation of MIS rates.

Continuation of Follow-up of DES-Exposed Cohorts
Breast CancerAutoimmune Disease3 moreDiethylstilbestrol (DES), a drug first synthesized in 1938, was administered to several million pregnant women in the U.S. and Europe for the prevention of spontaneous abortion and premature delivery. In 1971, Herbst reported a strong association between DES use in pregnancy and the occurrence of vaginal clear cell adenocarcinoma (CCA) in exposed female offspring. Animal models have demonstrated a range of DES effects on offspring exposed in utero, including reproductive dysfunction, immune system changes, behavioral and sexual abnormalities, and increases in various reproductive cancers in males and females. In the mid-1970's, several separate cohorts of DES-exposed daughters and unexposed comparison groups were followed for the occurrence of cancer, precursor lesions, and reproductive effects, but systematic follow-up of these cohorts had ceased by 1990. In 1992, Congress passed a bill (H;.R. 4178) mandating the continued follow-up of DES-exposed cohorts. The National Cancer Institute, in collaboration with five field centers, reassembled previously studied cohorts of DES-exposed and unexposed mothers, daughters and sons, and identified subjects with documented exposure status who had not been studied previously, through familial links within the cohorts. Standardized baseline questionnaires were mailed to cohort members to ascertain the risk of cancer and other disorders. Pathology reports were collected for reported cancers and preneoplastic conditions. Two separate rounds of follow up have been conducted and a third is almost complete. Patients from the Registry for Research on Hormonal Transplacental Carcinogenesis (the Registry) will be added to the follow-up effort in the third phase. The purpose of this study is to continue the follow-up, by means of mail questionnaires and medical record collection, which was begun during the first phase of the study. Concern has arisen that DES-exposed daughters may be at higher risk of breast cancer. Exposure to high levels of endogenous estrogen in utero has been hypothesized to increase the risk of breast cancer and DES is a potent estrogen. Cancer risk in the sons will also continue to be assessed, especially for increased risks of prostate cancer. Since the offspring who were exposed to DES in utero are currently reaching their late forties, when cancer rates begin to rise, it is important to continue the follow-up of these cohorts to determine if there are long-term increases in cancer risk.
