Comparison of tear protein levels in breast cancer patients and healthy controls using a de novo proteomic approach.

Noninvasive biomarkers are urgently needed for early detection of breast cancer since the risk of recurrence, morbidity and mortality are closely related to disease stage at the time of primary surgery. In the past decade, many proteomics-based approaches were developed that utilize the protein profiling of human body fluids or identification of putative biomarkers to obtain more knowledge on the effects of cancer emergence and progression. Herein, we report on an analysis of proteins in the tear fluid from breast carcinoma patients and healthy women using a de novo proteomic approach and 25 mixed samples from each group.

Antibody microarray analysis of the serum proteome in primary breast cancer patients.

Noninvasive biomarkers are urgently needed for detecting breast cancer as early as possible since the risk of recurrence, morbidity, and mortality is closely related to disease stage at the time of primary surgery. There are currently no such biomarkers in clinical use as a diagnostic tool. Proteomic analysis of protein expression patterns in body fluids has potential for use in identifying biomarkers of breast cancer.

Serum proteome profiling of primary breast cancer indicates a specific biomarker profile.

Non-invasive biomarkers for early breast cancer detection are urgently needed, as the risk of recurrent morbidity and mortality is closely related to the stage of the disease at the time of primary surgery. Currently, there are no established clinical biomarkers for breast cancer. Evaluation of protein expression patterns in body fluids using proteomic technologies can be used to discover new biomarkers for the detection of breast cancer.

Primary Leiomyosarcoma of the Male Breast.

We describe herein the third case of primary leiomyosarcoma of the breast in a 62-year-old man. Preoperative clinical examination and cytology findings indicated a leiomyosarcoma of the breast. A modified radical mastectomy was performed.
