Abstract. Even among breast cancer patients without metastasis to axillary lymph nodes, early recurrence can occur. To determine the risk factors for early recu.


To investigate the clinical significance of histologic grade 2 tumors with either a grade 1-like or a grade 3-like profile, we compared the relapse-free survival of patients who had grade 1–like histologic grade 2 tumors (i.e., gene expression grade 1) with that of patients who had grade 3–like histologic grade 2 tumors (i.e., gene expression grade 3) ( Fig. 2, B).

This tumor is graded using standard schemes in a 3-tier manner with the intermediate-grade category shows the most variability between grading systems and thus the most controversy in management. Histologic Grade I Invasive Ductal Carcinoma. This invasive ductal carcinoma consists of small angulated glands with fairly uniform nuclei. Grade I carcinomas tend to have be less aggressive and have a better prognosis than higher grade carcinomas. A histologic grade refers to how much tumor cells resemble normal cells when viewed under the microscope. The grading scale usually ranges from 1 to 3.

To evaluate the effect of age, the study population was divided into 2 groups (younger than age 50 years and age 50 years and older). 2016-09-21 NCI's Dictionary of Cancer Terms provides easy-to-understand definitions for words and phrases related to cancer and medicine. Physicians often examine hormone receptors in breast cancer cells at the time of biopsy or breast surgery to determine whether estrogen receptors (ER-positive) or progesterone receptors (PR-positive) are present. Patients whose cancers have ER or PR-positive receptors tend to have a better prognosis than patients whose cancers do not have these receptors.

What is a Histologic Grade System? Histology is the study of tissues, including cellular structure and function. Pathologists (physicians who conduct laboratory studies of tissues and cells) often assign a histologic grade to a patient’s cancerous breast tumor to identify the type of tumor present and help determine the patient’s prognosis (projected outcome).

About 1/2 of breast cancers are high grade and are identified by their lack of gland formation, large, bizarre, pleomorphic nuclei that vary in size… Histologic grade in breast cancer, though important and assessed for all tumors, is not integrated within tumor staging. Objective: To determine whether the histologic grade remains a prognostic factor for breast cancer regardless of tumor size and the number of involved axillary lymph nodes. Three grades are possible: Total score = 3–5: G1 ( Low grade or well differentiated) Total score = 6–7: G2 (Intermediate grade or moderately differentiated) Total score = … Histopathologic grade of a tumor may be used to plan treatment and estimate the future course, outcome, and overall prognosis of disease.
