Breast-Conserving Therapy is Associated with Improved Survival Compared with Mastectomy for Early-Stage Breast Cancer: A Propensity Score Matched Comparison Using the National Cancer Database
Introduction: The current recommendation for early-stage breast cancer is largely based on the NSABP B-06 trial showed similar survival between mastectomy and lumpectomy. We sought to compare breast conservation therapy (BCT) with mastectomy for early stage breast cancer treatment in a patient population contemporary.
Methods: A query of NCDB PUF identified female breast cancer patients diagnosed from 2004 to 2015. Patients with stage I or II disease were included. BCT was defined as receipt of lumpectomy plus radiation. propensity score tabulated using race, age, score Charlson / Deyo, tumor location, laterality, histology, grade, size, number of positive nodes, lymph-vascular invasion, receptor status, receiving chemotherapy and endocrine therapy.
Patients who received BCT compared to mastectomy matched using 1: 1 nearest neighbor technique. The main outcome measure was overall survival. Results: After exclusions and matching, two equal groups of 101 118 patients remained. Median follow-up was 42 months. The majority had invasive ductal histology (77%), and node-negative disease (84%). receptor status, including ER-positive (83%), PR-positive (73%), and HER2 / Neu positive (15%). 38% received chemotherapy and endocrine therapy in 71%.
Propensity score matching produce similar groups in all target variables. 5-year overall survival is superior to the BCT compared with mastectomy (92.9% vs 89.7%, p <0.001 ;. Figure 1). This survival advantage to survive for both phase I (p <0.001) and stage II (p <0.001) disease in the subgroup analysis. Picture. 1 overall survival in female patients with early stage invasive breast cancer (stage I or II) who underwent breast-conserving surgery with radiation compared to mastectomy. CONCLUSION BCS breast conserving surgery: BCT associated with superior overall survival compared to mastectomy for early stage breast cancer using a suitable, contemporary data.

Tomosynthesis mammography Imaging Screening Trial (TMIST): An Invitation and Opportunities for Communities National Medical Association to Shape the Future of Precision Screening for Breast Cancer
To determine the best screening modalities for breast cancer, a large randomized clinical trial is underway to compare the accuracy of mammography between standard digital mammography and tomosynthesis. The tomosynthesis mammography Imaging Screening Trial (TMIST) also built the world’s largest biorepository breast cancer specimens of all biopsy at screening and want to ensure it is representative of the US population.
We invite doctors of the National Medical Association, as a leader in the African American health care, to continue their commitment to eliminate the gap by promoting TMIST among African American women. The results of the trial will help to advance screening precision, individually adjust the screening decision is based on breast density, tumor subtyping and genomics. The partnership with the NMA is important to build confidence, dispel misunderstandings about clinical trials in the community as well as to support a cadre of African American physicians and researchers who can contribute to the current understanding of the social factors of breast cancer.
Description: This antibody reacts with a protein of ~13kDa, identified as alpha sub-unit of HCG. HCG is a glycoprotein which is secreted in large quantities by normal trophoblasts. HCG is present only in trace amounts in non-pregnant urine and sera but rises sharply during pregnancy. HCG is composed of two non-identical, non-covalently linked polypeptide chains designated as the alpha and beta subunits. The alpha subunit is identical to that of thyroid stimulating hormone (TSH), follicle stimulating hormone (FSH), and luteinizing hormone (LH).

Description: This mAb reacts with a protein of ~13kDa, identified as alpha subunit of Luteinizing Hormone (LH) or Chorionic Gonadotrophin (CG). The protein dimer contains 2 polypeptide units, labeled alpha and beta subunits that are connected by two bridges. The alpha subunits of LH, FSH, TSH, and hCG are identical, and contain 92 amino acids. The beta subunits vary. LH has a beta subunit of 121 amino acids (LHB) that confers its specific biologic action and is responsible for interaction with the LH receptor. This beta subunit contains the same amino acids in sequence as the beta subunit of hCG and both stimulate the same receptor; however, the hCG beta subunit contains an additional 24 amino acids and the hormones differ in the composition of their sugar moieties. LH is synthesized and secreted by gonadotrophs in the anterior lobe of the pituitary gland. In concert with the other pituitary gonadotropin follicle-stimulating hormone (FSH), it is necessary for proper reproductive function. In the female, an acute rise of LH levels triggers ovulation. In the male, where LH has also been called Interstitial Cell-Stimulating Hormone (ICSH), it stimulates Leydig cell production of testosterone. LH is a useful marker in classification of pituitary tumors and the study of pituitary disease.

In this retrospective study, we included newly diagnosed patients from 2004 to 2010. The study included 9266 patients with breast cancer who were enrolled in the treatment MDT and 9266 patients who did not. This study using the log-rank test to analyze the characteristics of patients, hospital characteristics, cancer staging and treatment methods to compare the recurrence rate in the treatment of non-MDT and MDT treatment of participants. We used Cox proportional hazards model to test the effect of MDT and related factors on the risk of recurrence and death from breast cancer patients.
