Published data from the Middle East and North Africa (MENA) region indicate suboptimal quality of cancer care, while the World Health Organization predicts an increase in cancer cases in developing countries. Major advances in breast cancer management mandate the development of guidelines to improve the quality and efficacy of oncology practice in the MENA region. A Breast Cancer Regional Guidelines Committee was organized and activated, comprising experts from various regional cancer institutions. The multidisciplinary team included 12 medical oncologists, 3 radiation oncologists, 2 radiologists, 2 surgeons, and 1 pathologist. The committee members agreed on adapting the current NCCN Clinical Practice Guidelines in Oncology (NCCN Guidelines) Breast cancer is the most common malignant disease in women, with an increasing incidence worldwide, especially in developing countries such as the Middle East and North Africa (MENA) region.1-3 However, the mortality rate has declined dramatically in developed on Breast Cancer for use in the MENA region to achieve common practice standards for treating patients. The members suggested several modifications to the guidelines, especially those related to risk factor profiles. United States-based NCCN experts reviewed these recommendations before final approval. The MENA-NCCN Breast Cancer Guidelines modification process was the first initiative in the development of common practice guidelines in the region. This project may serve as a foundation for the development of evidence-based practice standards, and improve collaborative projects and initiatives. (JNCCN 2010;8[Suppl 3]:S8-S15)
Phyllodes tumors are rare tumors that occur in relatively young women, when compared with the classical adenocarcinoma of the breast. They have a tendency to reach large sizes with absence of nodal metastasis. Although surgery is the mainstay of management, postoperative radiotherapy also appears to decrease the local recurrence rates in certain presentations.
MBC is a rare entity among breast carcinoma in Kuwait. Most of the cases present with poor prognostic indicators and often show lack of expression of ER, PR and Her2/neu.
Background: The Oncotype DX is a quantitative assay of the expression of 16 tumor-related genes and 5 reference genes that predicts the potential of adjuvant chemotherapy benefit in estrogen receptor (ER)-positive early breast cancer patients. The study aims to evaluate the impact of Oncotype DX as a tool for adjuvant treatment decision of ER-positive, HER2-negative, N0/N1 early-stage breast cancer patients and to determine which clinicopathological criteria derived the greatest advantage. Results: A hundred patients at a median age of 50 years were included. TNM stage distribution was 34, 63, and 3 patients for stages I, II, and IIIA respectively. Fifty-four patients had luminal A and 46 had luminal B tumors. The recurrence score (RS) results were low, intermediate, and high risk in 54, 34, and 12 patients respectively. Before the test results, adjuvant chemoendocrine therapy (CET) was recommended for 46 patients while 54 were advised for endocrine therapy (ET). After getting the test results, 25 patients received CET (1, 12, and12 patients in the low-, intermediate-, and high-risk groups respectively) and 75 received ET. Treatment change was documented in 37 patients (8 patients from ET to CET and 29 from CET to ET; p = 0.001, McNemar test). Treatment change was significant among patients ≤ 50 years, luminal B tumors, stage II and IIIA disease, and node-positive disease. Conclusion: Oncotype DX testing resulted in significant changes in the adjuvant treatment decisions in ER-positive, HER2-negative early breast cancer particularly in the case of young, luminal B, N1, and stage II-IIIA disease.
N-acetyl-i-glucosaminidase (NAG) activity measured in sera from 129 breast cancer patients was elevated (mean 18.2 units/l) compared with that in sera from 28 healthy women (11.6 units/l) (p =0.001). There was a weak correlation between NAG activity and carcinoembryonic antigen (CEA) and CA-153, but no relationship to age, menopausal status, node status, stage, histology of tumour or to steroid receptors. NAG, CEA and CA-153 were measured in periodic follow-up samples taken after surgery (up to 26 months) from 17 patients. NAG activity fluctuated within a narrow range, unlike CEA and CA-153. In 70% of cases the pattern was similar to at least one of the other markers, and was generally maintained at a higher level in patients who suffered relapse compared with those who remained disease-free up to the last follow-up, but was not significantly altered before relapse. The measurement of NAG activity is unlikely to be of value in predicting time or occurrence of relapse or of clinical utility in post-surgical therapy. Increased appearance in serum may aid metastasis by degrading the extracellular matrix and it may be better investigated as a predictor of progression from in situ to invasive and metastatic cancer.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
