The Effects of Short-term Preoperative Treatment With Hormonal Therapy on Gene Profiles in Breast Cancer

Summary

The investigators would like to study the genetic and molecular outcomes that results after a short term neoadjuvant hormonal therapy on patients with breast cancer.

Description

Breast cancer is among the most common malignancies in women in the United States. Over the years breast cancer management have dramatically developed from the extensive surgical approach toward the breast conservative approach. This was mainly due to the introduction of chemotherapy and hormonal therapy. Hormonal therapy in particular has been shown to improve the oncological outcomes of the breast cancer. However, while this is well documented in the clinical outcomes. Little is known in regards what happens on the genetic level. As such in this study the investigators would like to study the genetic and molecular outcomes that results after a short term neoadjuvant hormonal therapy on patients with breast cancer.

The hypothesis of this study is that short-term, preoperative hormonal treatment will induce genetic changes associated with reduced proliferation, including lower Ki67 expression, and changes in Estrogen Receptor (ER) and Progesterone Receptor (PR) expression. The data from such investigation will be very helpful in advancing the individualized care to women with breast cancer.

Tamoxifen Citrate, Letrozole, Anastrozole, or Exemestane With or Without Chemotherapy in Treating Patients With Invasive RxPONDER Breast Cancer

This randomized phase III clinical trial studies how well tamoxifen citrate, anastrozole, letrozole, or exemestane with or without chemotherapy work in treating patients with breast cancer...

Letrozole, Anastrozole, Exemestane, or Tamoxifen Citrate in Treating Postmenopausal Women With Breast Cancer

RATIONALE: Estrogen can cause the growth of breast cancer cells. Aromatase inhibitors, such as letrozole, anastrozole, and exemestane, may fight breast cancer by lowering the amount of est...

Exemestane Compared With Tamoxifen in Treating Postmenopausal Women With Primary Breast Cancer

RATIONALE: Estrogen can stimulate the growth of breast cancer cells. Hormone therapy using exemestane or tamoxifen may fight breast cancer by blocking the uptake of estrogen. It is not yet...

Exemestane Compared With Tamoxifen in Treating Postmenopausal Women With Breast Cancer

RATIONALE: Estrogen can stimulate the growth of breast cancer cells. Hormone therapy using exemestane may fight breast cancer by reducing the production of estrogen. It is not yet known if...

Tamoxifen Citrate or Letrozole With or Without Bevacizumab in Treating Women With Stage III or Stage IV Breast Cancer

This randomized phase III trial studies tamoxifen citrate or letrozole together with bevacizumab to see how well it works compared with tamoxifen citrate or letrozole alone in treating wom...

MammaPrint and BluePrint Molecular Diagnostics using targeted RNA Next-Generation Sequencing technology.

Next-generation DNA sequencing (NGS) is rapidly becoming an indispensable tool for genome-directed cancer diagnostics, but next-generation RNA sequencing (RNA-seq) is currently not standardly used in ...

Epigenetic silencing of SALL2 confers tamoxifen resistance in breast cancer.

Resistance to tamoxifen is a clinically major challenge in breast cancer treatment. Although downregulation of estrogen receptor-alpha (ERα) is the dominant mechanism of tamoxifen resistance, the rea...

Overcoming Tamoxifen Resistance by Regulation of Del-1 in Breast Cancer.

Hormone receptor-positive breast cancer accounts for nearly two-thirds of breast cancer cases; it ultimately acquires resistance during endocrine treatment and becomes more aggressive. This study eval...

Norcantharidin regulates ERα signaling and tamoxifen resistance via targeting miR-873/CDK3 in breast cancer cells.

MiR-873/CDK3 has been shown to play a critical role in ERα signaling and tamoxifen resistance. Thus, targeting this pathway may be a potential therapeutic approach for the treatment of ER positive br...

Retained products of conception in hysteroscopy in a patient with breast cancer on tamoxifen.

Tamoxifen is a selective oestrogen receptor modulator widely used in breast cancer treatment, with good survival rates. Its partial agonist action on other tissues such as the uterus, however, promote...

Medical and Biotech [MESH] Definitions

Abnormal accumulation of lymph in the arm, shoulder and breast area associated with surgical or radiation breast cancer treatments (e.g., MASTECTOMY).

Metastatic breast cancer characterized by EDEMA and ERYTHEMA of the affected breast due to LYMPHATIC METASTASIS and eventual obstruction of LYMPHATIC VESSELS by the cancer cells.

A infiltrating (invasive) breast cancer, relatively uncommon, accounting for only 5%-10% of breast tumors in most series. It is often an area of ill-defined thickening in the breast, in contrast to the dominant lump characteristic of ductal carcinoma. It is typically composed of small cells in a linear arrangement with a tendency to grow around ducts and lobules. There is likelihood of axillary nodal involvement with metastasis to meningeal and serosal surfaces. (DeVita Jr et al., Cancer: Principles & Practice of Oncology, 3d ed, p1205)

A deoxycytidine derivative and fluorouracil PRODRUG that is used as an ANTINEOPLASTIC ANTIMETABOLITE in the treatment of COLON CANCER; BREAST CANCER and GASTRIC CANCER.

Carbohydrate antigen elevated in patients with tumors of the breast, ovary, lung, and prostate as well as other disorders. The mucin is expressed normally by most glandular epithelia but shows particularly increased expression in the breast at lactation and in malignancy. It is thus an established serum marker for breast cancer.
