    Article - En anglais

    Background

    The Quebec Neuroblastoma Screening Project was initiated to assess clinical and biologic aspects of neuroblastomas detected by screening infants born in the province of Quebec from May 1,1989, to April 30,1994.

    Methods

    Infants were screened for preclinical detection of neuroblastoma by determination of catecholamine metabolites, vanillylmandelic acid (VMA), and homovanillic acid (HVA).

    Patients with tumors discovered through this screening as well as patients in the same birth cohort with clinically detected tumors were referred to Quebec Oncology Centers for further investigation, diagnosis, and treatment.

    Pathology specimens were submitted to Childrens Hospital Los Angeles for central review.

    Tumors were histopathologically classified according to the Shimada system.

    Results

    As of August, 1993,340,000 infants were screened at 3 weeks and 245,000 of them were retested at 6 months of age.

    Thirty-one tumors were detected through this screening and removed.

    Histologic material was available for 27 cases 

    14 were detected at 3 weeks of age and 13 at 6 months of age.

    Twenty-six patients had tumors with favorable histology (FH), and one patient had a Stage I tumor with unfavorable histology (UH).

    At the time of this writing, all mass screening patients are alive, including one child with relapsed disease.

    During this period, 48 tumors were detected clinically in the same birth cohort, 40 of which were evaluated histologically.

    Of these 40 cases, ...
