Official Title: Granulomatous Mastitis Current Approach and Treatment (Multicentric Study) Granulomatous Mastitis Working Group

Brief Summary:

The aim of this study was to retrospectively review the granulomatous mastitis and evaluated current approach and treatment.

HYPOTHESIS Although there is no common protocol for the treatment and management process of GM, the ternary treatment (medical treatment following by surgical procedure, Steroid+Antibiotic and surgical procedure, respectively) is considered as the most successful treatment approach.


Detailed Summary:

INTRODUCTION Granulomatous mastitis (GM) is a rare inflammatory disease of the breast which generally affects young parous women. It was emphasized that lactation and using oral contraceptive are considered among the predisposing factors of the disease. GM is firstly identified in 1972, and it is considered as an important disease because it is a great mimicker of breast carcinoma.

The form of treatments involves corticosteroids, antibiotics and general surgical resections including mastectomy. Furthermore, a preferred form of treatment has not been defined yet. Also, there are not enough data showing the results of using antibiotics. Since GM is a rare disease, there is no common consensus for the diagnosis and treatment of GM. The uncertainties about the distinct diagnosis, determining the form and term of treatment, the order of treatment if necessary, as well as what medical specialties need to involve in the treatment process still remain. Therefore, all these uncertainties cause a difficulty to manage the treatment process by physicians. Furthermore, since there is no enough study on GM and only limited case reports was presented in the literature, the success of treatment process is associated with the experience of treatment center. Therefore, there is a clear need for multicentric study that compares different approaches of the treatment process with the enough number of cases.

DATA COLLECTION In this study, patient's data will be retrospectively obtained by recording the data in patients' files and electronic records. The data includes the determined parameters by the study group of GM and the data will be recorded in an excel file that includes specific columns of the following entries: patients' age, diagnosis, secondary disease, diagnosis methods, treatments, recurrence, the risk factors that may cause the dis

Current Primary Outcome: Granulomatous Mastitis Working Group [ Time Frame: dec 2015 start data collection, February 2016 The primary outcome statement - April 2016 end up study ]

The data includes the determined parameters by the study group of GM and the data will be recorded in an excel file that includes specific columns of the following entries: patients' age, diagnosis, secondary disease, diagnosis methods, treatments, recurrence, the risk factors that may cause the disease. A shared excel file at the following website http://sanko.edu.tr/GranulamatozMastit has been created to record the data simultaneously. Each researcher can add the data at the file by using username and password. After data collection, statistical analysis will include Mann-Whitney U test, student's t test and chi-square test and statistical significance will set at P< 0.05.The sample size and power analysis were conducted and the results indicated that at least 100 samples in each group are required to achieve the statistical significance at P< 0.05 with 90% power. The estimated total cases are expected over 400 cases.
