Lapatinib in Combination With Radiation Therapy in Patients With Brain Metastases From HER2-Positive Breast Cancer

The purpose of this research study is to determine the safety of combining lapatinib plus radiation in patients with breast cancer that has spread to the brain. Depending upon the partici...

Fulvestrant With or Without Lapatinib in Treating Postmenopausal Women With Stage III or Stage IV Breast Cancer That is Hormone Receptor-Positive

RATIONALE: Estrogen can cause the growth of breast cancer cells. Hormone therapy using fulvestrant may fight breast cancer by lowering the amount of estrogen the body makes. Lapatinib may ...

ELBA: Exemestane and Lapatinib in Advanced Breast Cancer

Aromatase inhibitors are the standard treatment for hormone responsive advanced breast cancer. The combination of the aromatase inhibitor exemestane with with another breast cancer drug t...

Lapatinib and Tamoxifen in Treating Patients With Advanced or Metastatic Breast Cancer

RATIONALE: Lapatinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Estrogen can cause the growth of breast cancer cells. Hormone therapy using ...

Lapatinib in Combination With Trastuzumab in Patients With HER2-Positive, Metastatic Breast Cancer

In this research study we are studying the effects of the combination of lapatinib plus Herceptin in subjects with breast cancer that has spread outside of the breast. We are also studying...

Fibulin-1 interacts with Sex Hormone Binding Globulin and is linked to less aggressive estrogen-dependent breast cancers.

Interaction of Sex Hormone-Binding Globulin (SHBG) with estrogen-sensitive breast cancer cells has a protective role against estrogen exposure. No specific membrane receptor for SHBG had been identifi...

Comment on a meta-analysis evaluating the cardiac toxicity of lapatinib in patients with breast cancer and other HER2-positive cancers.

The use of breast imaging for predicting response to neoadjuvant lapatinib, trastuzumab and their combination in HER2-positive breast cancer: Results from Neo-ALTTO.

To determine the value of mammography and breast ultrasound (US) in predicting outcomes in HER2 positive breast cancer patients (pts) within Neo-ALTTO trial.

Survival Analysis After Neoadjuvant Chemotherapy With Trastuzumab or Lapatinib in Patients With Human Epidermal Growth Factor Receptor 2-Positive Breast Cancer in the GeparQuinto (G5) Study (GBG 44).

Purpose The GeparQuinto phase III trial demonstrated a lower pathologic complete response (pCR; pT0 ypN0) rate when lapatinib was added to standard anthracycline-taxane chemotherapy compared with tras...

Hormone Therapy in Breast Cancer Survivors and Those at High Risk for Breast Cancer.

Women and health care providers are often fearful of using hormone therapy to deal with distressing menopausal symptoms in circumstances where there is a perceived or real increased risk of breast can...

Medical and Biotech [MESH] Definitions

Antineoplastic agents that are used to treat hormone-sensitive tumors. Hormone-sensitive tumors may be hormone-dependent, hormone-responsive, or both. A hormone-dependent tumor regresses on removal of the hormonal stimulus, by surgery or pharmacological block. Hormone-responsive tumors may regress when pharmacologic amounts of hormones are administered regardless of whether previous signs of hormone sensitivity were observed. The major hormone-responsive cancers include carcinomas of the breast, prostate, and endometrium; lymphomas; and certain leukemias. (From AMA Drug Evaluations Annual 1994, p2079)

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.
