Despite different clinical characteristics including the response to treatment and the patterns of metastatic relapse, invasive lobular breast carcinoma (ILBC) is treated like invasive ductal breast carcinoma (IDBC) carcinoma both in the clinics and in clinical trials. A large majority of ILBC are ER+/HER2- and almost 90% have loss of E-cadherin (CDH1) expression. A non-clinical study of CDH1 synthetic lethality interactions has identified ROS1 as a potential target. In vivo, ROS1 inhibitors produced profound antitumor effects in multiple models of E-cadherin-defective breast cancer, providing the preclinical rationale for assessing ROS1 inhibitors in this setting. Endocrine therapy being the mainstay of therapy for ER+/HER2- ILBC and the pre-operative setting offering a platform for rapid drug evaluation and biomarker research, the ROSALINE phase 2 study will evaluate the efficacy of Entrectinib (a potent inhibitor of ROS1 among other targets) in combination with letrozole (+ goserelin in premenopausal women) in the early setting of ILBC (stages 1 to 3). The neoadjuvant therapy will last 4 months and post-operative therapy will follow local practice. Biomarker research will include RNA sequencing of initial biopsies and surgical specimens, as well as liquid biopsies.
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.
FES PET/CT imaging for invasive lobular cancer
This phase II trial studies how well abemaciclib works in treating patients with triple negative breast cancer that can be removed by surgery (resectable) and does not respond to treatment with chemotherapy alone, or in combination with pembrolizumab. Abemaciclib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth.
This study is evaluating how ruxolitinib affects premalignant breast cells. One half of the study participants will receive ruxolitinib for approximately 15 days, and the other half will receive a placebo (sugar pill) for approximately 15 days. Once study participants have completed their ruxolitinib or placebo, participants will undergo surgery to remove the premalignant breast tissue.
The purpose of this study is to evaluate a novel neoadjuvant regimen for invasive breast carcinoma by using the MD Anderson residual cancer burden score.To prospectively evaluate the utility of the PET scan to guide the neoadjuvant treatment and the utility of the Oncotype test as a stratifier for treatment decisons in ER+/Her2- patients. To evaluate the clinical anti-tumor activity of neoadjuvant hormonal therapy in ER+/Her2 negative patients. To evaluate the prognostic factors associated associated with pathological response as measured by the residual cancer burden tool.
F18-FDG is the widely used PET tracer in the routine practice of oncologic disease imaging using the technology of PET-CT. However, FDG-avidity is a characteristic of the individual tumor. There are various types of human malignancies, which are not taking FDG in access. In these cases FDG is not a sensitive tracer of imaging. In search for other tumor PET tracers, C11-Acetate has been shown recently in a few early studies to have a potential value in imaging of non-FDG-avid tumors. The purpose of the current study is to assess the role of 11C-acetate PET in various tumors, which often are not detected by 18F-FDG and were not widely assessed until now.
RATIONALE: Gathering information about genetic changes in patients with lobular carcinoma in situ of the breast may help doctors learn more about the disease and find better methods of treatment. PURPOSE: This clinical trial is studying the genetics of women with lobular carcinoma in situ of the breast.
