Brief Summary:
Congenital lung anomalies include different pathologies such as congenital cystic adenomatoid malformation, pulmonary sequestration, bronchial atresia, emphysema, bronchogenic cyst. They concern less than 1/10000 births and their physiopathological origin is still poorly understood. The main goal of this project is to pool the cases from different swiss centers on a prospective cohort study, first to increase knowledge of clinical and radiological evolution and their correlation with histological data, and second to analyse the pathological embryological mechanism underlying these malformations.

Condition or disease Intervention/treatment
Congenital Lung Malformation Congenital Lung Cyst Sequestrum Bronchogenic Cancer Pleuropulmonary Blastoma Acinar Dysplasia Procedure: Malformations resection

Detailed Description:
  1. To register prospectively clinical, biological, radiological and histological datas in a multicentric database (secured internet link, via Secutrial® software). for children with prenatal diagnosis of this kind of malformation. This study is conducted by a multidisciplinary team, involving obstetricians, neonatologists, pneumologists, pediatric surgeons, radiologists and anatomopathologists.
  2. To create a tissue biobank

Outcomes:

  1. Contribute to the definition of a standardized procedure at the Swiss level for the treatment of patients suffering from these malformations,
  2. Improve the assessment of lesion evolution related to CLA, and
  3. Possibly validate some biomarkers, which could help to identify individuals at risk. On the long term, these results could also support the development of innovative therapies targeting the factors involved in lung development.

Study Type : Observational [Patient Registry]
Estimated Enrollment : 100 participants
Observational Model: Cohort
Time Perspective: Prospective
Target Follow-Up Duration: 10 Years
Official Title: Follow up of Congenital Lung Anomalies (CLA) With Antenatal Diagnosis - a Swiss Multicentric Database
Study Start Date : April 1, 2016
Estimated Primary Completion Date : January 1, 2020
Estimated Study Completion Date : April 1, 2026


Group/Cohort Intervention/treatment
Patient with CLA with surgery Procedure: Malformations resection
Resection of the malformation lung sections with a healthy adjacent part

Patient with CLA without surgery



Primary Outcome Measures :
  1. Change in clinical of patients with CLA between different time point [ Time Frame: Birth, 1 month of life, 4 months of life, 9-18 months of life, 6 months post surgery, 1 year post surgery, 7 years old, 10 years old, 12 years old ]
    Clinical measurements: size (cm), weight (kg), saturation (%)

  2. Analysis of CLA physiopathology [ Time Frame: samples collected during surgery ]
    Analysis of growth factors, transcription factors and extracellular components implicated in CLA genesis by immunohistochemistry, transcriptomic and proteomic methods

  3. Change in lung function [ Time Frame: 7 years old,10 years old, 12 years old, 16 years old ]
    FEV1 (l/min), FEV1/FVC (%)TLC (L) DLCO (ml/min/mmHg)

  4. Change in Scar aspect and thoracic deformation of patients with CLA between different time point [ Time Frame: 6 months post surgery, 1 year post surgery, 7 years old, 10 years old, 12 years old ]
    Description

  5. Change in lung radiological images of patients with CLA between different time point [ Time Frame: 1 month of life, 4 months of life, 9-18 months of life, 6 months post surgery, 1 year post surgery, 7 years old, 10 years old, 12 years old ]
    Chest X-ray and Thoracic CT Scan lesion description

  6. Change in lesion size described by antenatal ultrasound of patients with CLA between different time point [ Time Frame: 22, 28, 32 and 37 weeks of gestation ]
    lesion size (mm) CVR, estimated wight (gr), Head circumferences (cm)

  7. Change in lesion description by antenatal ultrasound of patients with CLA between different time point [ Time Frame: 22, 28, 32 and 37 weeks of gestation ]
    Lesion description (micro cysts, macrocysts),lesion localisation


Secondary Outcome Measures :
  1. Report biomarkers implicated in CLA with a potential role in lesion oncogenic transformation [ Time Frame: 1 year post surgery ]
    Comparison using exome analysis : CLA lesion, healthy adjacent part and blood DNA


Biospecimen Retention:   Samples With DNA
To create a biobank with the different samples of patients undergoing surgery, healthy edge of resections being considered as control tissue. Leukocyte DNA will be compared with lung tissue DNA.
