Validity and Reliability of the Mastitis Symptom Severity Assessment Methods (M-Score and BISSI) in Non-Lactational Mastitis

The purpose of this study is to evaluate the validity and reliability of the Mastitis-score (M-score) and the Breast Inflammatory Symptom Severity Index (BISSI) as measures for assessing symptom severity in non-lactational granulomatous lobular/periductal mastitis (NL-GLM/PDM). This research aims to provide a valid and reliable tool for evaluating both symptom severity and treatment efficacy in NL-GLM/PDM.

Antibiotics vs Corticosteroids in Treatment of Granulomatous Lobular Mastitis

The goal of this clinical trial is to find the most effective and safe medical treatment for Granulomatous Lobular Mastitis (GLM) - a rare, chronic inflammatory breast disease that affects young and middle-aged women, often following childbirth. The main questions it aims to answer are: Does an antibiotic regimen (clarithromycin, ofloxacin, rifaximin) lead to faster and complete healing (Complete Clinical Response) compared to steroids? Do steroids (prednisolone in tapering doses) provide better symptom control or cause more side effects? Researchers will compare the antibiotic group (Group A) and the steroid group (Group B) to see which treatment results in quicker recovery, fewer side effects, and lower recurrence rates. Participants will: Receive a 14-day antibiotic trial initially (screening phase). If no improvement, be randomly assigned to: Group A (Antibiotic therapy) - Clarithromycin, Ofloxacin, Rifaximin for 8 weeks, or Group B (Steroid therapy) - Prednisolone in tapering doses for 8 weeks. Undergo evaluation after 2 months: If not fully recovered, receive Methotrexate + Folic acid for another 8 weeks. If still no improvement, switch to the alternate treatment or undergo surgery if required. Attend regular follow-ups for 6 months for clinical assessment and monitoring of side effects. This 2-year study aims to develop a standardized, step-by-step treatment protocol for GLM, helping improve outcomes and reduce unnecessary surgeries for affected women.

GRAnulomatous MAstitis REGistry Study

Idiopathic granulomatous mastitis (IGM) is a rare benign inflammatory breast condition with unknown cause, affecting approximately 2.4 per 100,000 women aged 20-40 years. Patients experience severe local symptoms including pain, redness, and recurrent abscesses that can last weeks to months and often mimic inflammatory breast cancer. Due to its rarity, mostly case reports and case series exist in the literature, leading to limited knowledge about risk factors, optimal treatment strategies, and clinical outcomes. The GRAMAREG study is the first European registry for patients with histologically confirmed idiopathic granulomatous mastitis. This retrospective/prospective observational cohort study aims to systematically evaluate the incidence, diagnostic features, clinical course, treatment strategies, and patient outcomes of this uncommon disease. The study collects both retrospective data (from January 1, 2015 onwards) and prospective data from participating sites across Europe. All diagnostic and therapeutic procedures are conducted according to institutional standards in clinical routine, as this is a non-interventional study. Patients in the prospective cohort are followed for up to 5 years to document symptom duration and recurrence rates.

Observation Alone for Mild Non-Lactational Mastitis

The goal of this observational study is to investigate the disease progression rate and timing in patients with mild Non-Lactational Granulomatous Lobular / Periductal Mastitis (NL-GLM/PDM) during follow-up with observation alone strategy. The main questions it aims to answer are: What is the rate of disease progression in mild NL-GLM/PDM patients under observation, and what clinical and pathological factors are associated with this progression? Participants with diagnosis of mild NL-GLM/PDM will be monitored over a specified period, with data collected on their clinical outcomes and relevant factors influencing disease progression.

Effect of Different Surgical Approaches of Granulomatous Mastitis

The objective of this study was to prospectively investigate the effects of different surgical approaches on the recurrence rate and aesthetic outcome of patients with granulomatous mastitis. The patients were divided into traditional surgery group and plastic surgery group.

Analysis of Various Treatment Methods of Granulomatous Lobular Mastitis

Granulomatous lobular mastitis (GLM) is a rare benign breast disease that is difficult to distinguish from breast cancer based on clinical and imaging findings, and there is currently no standard treatment. This study aims to analyze the clinical characteristics and demographic data of GLM patients and to compare the overall effectiveness of three treatment methods: surgery alone, triple anti-tuberculosis drug therapy alone, and combined surgery with triple anti-tuberculosis drug therapy, with the goal of providing new insights for clinical treatment.
