Filter by:The purpose of this study is to establish a standardized process for obtaining digital pathological image information of ocular tumors; use modern pathological techniques to obtain the co-expression information of multiple biomarkers in the pathological tissues of ocular tumors, and finally construct standardized digital ocular tumors with biomarkers Pathology image database.
Ductal carcinoma in situ (DCIS) accounts for approximately 20% of newly diagnosed breast cancer cases. Of these women, 20% require radical management in the form of mastectomy because of the extent of the lesions, which most often manifest as diffuse microcalcifications. This mutilating surgical management contrasts with the excellent prognosis of this pathology and considerably alters the quality of life of patients. Neoadjuvant hormone therapy has shown its efficacy in hormone-dependent infiltrating ductal carcinomas and offers the possibility of conservative surgery after hormone therapy. Adjuvant hormone therapy with Tamoxifen or anti-aromatase drugs has shown its efficacy in the prevention of homo or contralateral recurrence. The HORNEO 01 trial fits perfectly in the current context of surgical de-escalation of ductal carcinomas in situ. The objective of the study is to evaluate the impact of neoadjuvant hormone therapy on the surgical management of extensive DCIS.
This is a prospective, registry study that will enroll all women with early stage breast cancer who will be treated with intraoperative radiotherapy (IORT) during breast-conserving surgery. The purpose of this study is to further validate the long-term effectiveness and safety of this treatment method. We aim to assess short and long-term patient outcomes associated with IORT, including perioperative complications, local and distance disease recurrences, as well as disease-free survival and overall survival.
This phase II trial studies the effect of megestrol acetate alone or in combination with metformin in preventing the progression of uterine pre-cancer (endometrial intraepithelial neoplasia) to endometrial cancer. Megestrol acetate is a drug used to block estrogen and suppress the effects of estrogen and androgens. It is the current non-surgical treatment of endometrial intraepithelial neoplasia. Metformin is a drug that has been found to have anti-cancer properties. Giving metformin and megestrol acetate together may decrease the growth of endometrial intraepithelial neoplasia in the uterus better than megestrol alone.
The investigators plan to prospectively study breast tissue changes after a short course of Tamoxifen (Tam).
The investigators have developed a portable, battery-operated, mobile high-resolution microendoscope (mHRME) that provides subcellular images of the anal epithelium, delineating the cellular and morphologic changes associated with neoplasia. The investigators' central hypothesis is that this 'optical' approach will increase the efficiency, clinical impact, and cost-effectiveness of the current standard of high-resolution anoscopy(HRA)-guided biopsy, thus facilitating usage by less-experienced clinicians in community-based or low-resource settings. To validate this, the investigators will conduct a study to determine the efficiency and diagnostic characteristics of the mHRME 'optical biopsy' approach versus the current standard of HRA-based tissue biopsy. Successful results will allow for improved efficacy and resource utilization for cancer screening in people living with HIV for anal cancer and other epithelial cancers including the cervix, oral cavity, bladder, and GI tract.
This is a pilot study to determine safety, efficacy, and potential risks of robot assisted nipple sparing mastectomy (RNSM), by utilizing the daVinci surgical system.
This study examines at-home monitoring of patient-generated phsyiologic health data and patient-reported outcomes. Patient-generated health data using at-home monitoring devices and smart device applications are used more and more to measure value and quality in cancer care. This trial may show whether at-home monitoring programs can improve the care of patients after hospital discharge from surgery.
It is considered that whether or not the accompanying invasive cancer classified through MRI images of breast cancer patients identified as Ductal Carcinoma in situ (DCIS) through preoperative tissue biopsy is significantly consistent with the postoperative stage. Therefore, this study intend to evaluate the effectiveness as a diagnostic tool that can help determine the axillary lymph node surgery by predicting the possibility of post-operative up-staging using magnetic resonance imagings of breast cancer patients who have been identified as ductal carcinoma in situ and are scheduled for surgery.
This trial studies the implementation of web-based decision support tools for patients with atypical hyperplasia or lobular carcinoma in situ and healthcare providers. Decision support tools are designed to improve informed choice about breast cancer chemoprevention. Recognizing barriers and facilitators that can influence the adoption of decision support tools at recruitment centers may help researchers learn how to best implement them into clinical practice.
