[Quality control in pathology and theranostics in head and neck cancers].

Head and neck malignant tumors diagnosis require both standardized technical and personalized management in order to optimize patient care and therapy. The quality of multidisciplinary discussion for that goal needs common vocabulary. More than morphology, immunohistochemistry and in situ hybridization, additional molecular theranostics approaches are in fast progress in head and neck cancers, as well as their other anatomic counterparts.

Geographical variations in the incidence of childhood acute leukaemia in France over the period 1990-2004.

Spatial variations in childhood acute leukaemia (AL) incidence rates were investigated by département, in mainland France, over the period 1990-2004. This is the first spatial study of this incidence to cover a 15-year period. French National Registry of Childhood Haematological Malignancies data and population counts by type of leukaemia (AL, acute lymphoblastic leukaemia, acute myeloblastic leukaemia), time period (1990-2004, 1990-1994, 1995-1999 and 2000-2004), sex, and age group (0-14, 0-4, 5-9 and 10-14 years of age) were considered.

Course and prognosis of basaloid squamous cell carcinoma of the head and neck: a case-control study of 62 patients.

Objective: To describe the natural history and evaluate the prognosis of basaloid squamous cell carcinoma (BSCC) of the upper aero-digestive tract as compared to the usual squamous cell carcinoma (SCC).

Materials And Methods: Sixty-two patients with BSCC and 62 patients with SCC were matched with regards to TNM classification, localisation and therapeutic modalities. Histological criteria, follow-up and 5-year survival were compared among the two groups.

Tumor-specific methylation in saliva: a promising biomarker for early detection of head and neck cancer recurrence.

Purpose: Our goal was to define tumor and saliva gene methylation profile of head and neck squamous cell carcinoma and to evaluate its prognostic significance and its biomarker potential for early detection of relapse.

Experimental Design: We prospectively analyzed 11 genes by methylation-specific PCR on primary tumors, histologically normal adjacent mucosa, and saliva from 90 French patients at diagnosis and during follow-up as well as on 30 saliva specimens from control-matched patients with nonmalignant head and neck pathology. Five additional genes were analyzed on 50 tumors of the series.
