About this study

Official title: Ductal Lavage in Non-lactating Female Women With Mastitis: A Single Arm, Observational Study

RATIONALE and PURPOSE: For non-lactational mastitis patients pathologically diagnosis of idiopathic granulomatous mastitis (IGM) or periductal mastitis (PD), the investigators hypothesized that ductal lavage is able to relieve the symptoms and achieve complete response, with shorter recovery time than oral intake of antibiotics or corticosteroids treatments. This single arm, observational, case series, pilot study is going to evaluate the effectiveness of ductal lavage in patients with non-lactational IGM or PD.

Read the detailed description

Inflammatory non-lactating breasts diseases encompasses a large spectrum of diseases ranging from infective diseases to autoimmune diseases, which cause considerable morbidity and difficulty in diagnosis. In daily practices, exclusion of possible diagnosis of breast carcinoma is the most important step. Aetiological factors for non-lactational mastitis include bacterial infection, tuberculosis, auto-immune disorders, etc. Treatments for these patients including antibiotics, anti-tuberculosis therapy, and corticosteroids treatments. Many of these patients were pathologically diagnosed as periductal mastitis (PD) or idiopathic granulomatous mastitis (IGM). The current treatment for PD or IGM include corticosteroids treatments, antibiotics and surgical treatments. Based on literature review, the complete response (CR) rate of corticosteroids and surgical treatment ranged between 63-87% and 89-100%, respectively. Time to CR ranged between 2-8 month for corticosteroid treatment.

Pathological findings of patients of IGM or PD revealed infiltrating inflammatory cells and neutrophilic microabscesses around the lobular units and partial ductal obstruction, we hypothesized that ductal lavage therapy will be able to relieve the symptom by dilating the lactiferous duct followed by irrigation solution flushing, with shorter recovery time and satisfactory CR rate. In our institution(Sun Yat-sen Memorial Hospital,Guangzhou, Guangdong, P.R.China), it is our routine practice to perform ductal lavage therapy to patients with non-lactating breasts diseases, especially for patients with IGM or PD, before we start corticosteroid or antibiotics treatments. For patients with evidence of bacterial infection, antibiotics was added into the irrigation solution. In our experience, many patients had short recovery time and low relapse rate, sparing the use of corticosteroid or antibiotics treatments. However, there is no concrete data to quantify the efficacy of ductal lavage therapy for IGM or PD patients. This observational study aims to prospectively enroll eligible patients and investigate the efficacy of ducal lavage therapy in IGM or PD patients.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Ductal lavage therapyProcedure or surgery

    1. Patient lies in supine position, with routine sterilizing and draping procedure.
    2. Local anesthesia with 2ml lidocaine (1%) around the nipple.
    3. Identification of 4-5 openings of the lactiferous ducts from the nipple.
    4. Insertion of all infusion cannula (21-23G ) into the identified openings of the lactiferous ducts.
    5. Start the infusion pump with 15ml irrigation solution (2% Lidocaine 5ml, Triamcinolone acetonide 40mg,0.9% saline 10ml and ceftriaxone 1.0g). If the patients had elevated white blood cell count and fever (>38 celsius degree), oral intake or infusion of antibiotics were allowed, when necessary.
    6. The patient returns to the clinic the next day, with the irrigation solution staying in the lactiferous ducts overnight, and receives breast massage.
    7. Repeat step 1-6 every other day for 2 weeks.
    8. Fine needle aspiration is allowed. Oral intake of corticosteroids, excisional drainage or surgery are not allowed.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Time to complete response

    The length of time from the date of initial treatment to the date of complete response. Complete response (CR) was defined as reaching all of the followings: 1) visual analogue score <=1; 2) Disappearance of all local symptoms, such as redness, pain, swollen, etc. 3) Disappearance of fistula, if any; 4) The patient can return to normal life without any medical assistant.5) Disappearance of palpable or ultrasound detectable mass were defined as physical-CR and imaging-CR, respectively.

    Measured: Time from the initial treatment to first assessment of complete response, reported between day of first treatment and 1 year thereafter.

Secondary outcomes (4)
  1. Complete response rate

    The proportion of patients with complete response within 1 year after the initial treatment.

    Measured: Evaluations were performed every week for the 1st month, and every other month thereafter until complete response, reported between the day of first treatment and 1 year thereafter.

  2. Partial response rate

    The proportion of patients with partial response within 1 year after the initial treatment. Partial response was defined as reaching all of the followings: 1) decreased visual analogue score>=2; 2) Significantly relieved of all local symptoms, such as redness, pain, swollen, etc. 3) Disappearance of spontaneous discharge through fistula, if any; 4) The patient stated that the symptom is relieved significantly.5) Size of the target mass (Largest dimension) is reduced >30%, compared with that of the baseline. Partial response assessed by physical and ultrasound were defined as physical-partial-response and imaging-partial-response, respectively.

    Measured: Evaluations were performed every week for the 1st month, and every other month thereafter until partial response, reported between the day of first treatment and 1 year thereafter.

  3. Relapse incidence after complete response

    The incidence of relapse after complete response, within 1 year after the initial treatment. Definition of relapse including any of the followings: 1) Notice of new palpable mass; 2) Notice of new fistula; 3) Notice of new local symptoms, such as pain, redness, swollen and heated skin. Only patients with complete response during the study follow-up will be assessed for this outcome.

    Measured: Evaluations were performed every week for the 1st month, and every other month thereafter until relapse, reported between the day of complete response and 1 year after the initial treatment.

  4. Progression incidence after partial response

    The incidence of progression after partial response, within 1 year after the initial treatment. Definition of progression including any of the followings: 1) Progression of local symptoms (redness, swelling, tenderness, pain, fever) significantly. ; 2) Notice of new fistula; 3) The size of the target mass (Largest dimension) increased >20%, compared with that of the day of partial response. Only patients with partial response during the study follow-up will be assessed for this outcome.

    Measured: Evaluations were performed every week for the 1st month, and every other month thereafter until disease progression, reported between the day of partial response and 1 year after the initial treatment.
