Abstract
Background Nasal intestinal-type adenocarcinomas (ITAC) are strongly related to chronic wood dust exposure: The intestinal phenotype relies on CDX2 overexpression but underlying molecular mechanisms remain unknown. Our objectives were to investigate transcriptomic and methylation differences between healthy non-exposed and tumor olfactory cleft mucosae and to compare transcriptomic profiles between non-exposed, wood dust-exposed and ITAC mucosa cells.
Methods We conducted a prospective monocentric study (NCT0281823) including 16 woodworkers with ITAC, 16 healthy exposed woodworkers and 13 healthy, non-exposed, controls. We compared tumor samples with healthy non-exposed samples, both in transcriptome and in methylome analyses. We also investigated wood dust-induced transcriptome modifications of exposed (without tumor) male woodworkers’ samples and of contralateral sides of woodworkers with tumors. We conducted in parallel transcriptome and methylome analysis, and then, the transcriptome analysis was focused on the genes highlighted in methylome analysis. We replicated our results on dataset GSE17433. Results Several clusters of genes enabled the distinction between healthy and ITAC samples. Transcriptomic and IHC analysis confirmed a constant overexpression of CDX2 in ITAC samples, without any specific DNA methylation profile regarding the CDX2 locus. ITAC woodworkers also exhibited a specific transcriptomic profile in their contralateral (non-tumor) olfactory cleft, different from that of other exposed woodworkers, suggesting that they had a different exposure or a different susceptibility. Two top-loci (CACNA1C/CACNA1C-AS1 and SLC26A10) were identified with a hemimethylated profile, but only CACNA1C appeared to be overexpressed both in transcriptomic analysis and in immunohistochemistry. Conclusions Several clusters of genes enable the distinction between healthy mucosa and ITAC samples even in contralateral nasal fossa thus paving the way for a simple diagnostic tool for ITAC in male woodworkers. CACNA1C might be considered as a master gene of ITAC and should be further investigated.

Abstract
The aim of the present study was to investigate the role of wood dust exposure in intestinal (ITAC) and non-intestinal type (non-ITAC) nasal adenocarcinoma, so as to improve understanding of the oncogenic mechanisms in the light of the recent literature and of evo-devo concepts. MATERIALS AND METHODS All consecutive patients operated in our institution for nasal adenocarcinoma diagnosed on anatomopathology between May 2004 and February 2014 were included. Surgical specimens were examined twice by independent pathologists, blind to wood dust exposure status. Clinical and demographic data, including wood dust exposure, were collected for the two groups (ITAC and non-IATC). RESULTS 90 patients (84 ITAC, 6 non-ITAC) were included. No non-ITAC patients had history of wood dust exposure, versus 83/84 cases (99%) in ITAC (mean exposure duration: 30±16 years; range 2-65 years). Only 12 ITAC patients (18%) were still exposed at diagnosis. ITAC may develop long after the end of wood dust exposure (up to 60 years). Eight patients (12%) had exposure durations of less than 5 years. Latency between onset of exposure and onset of disease did not decrease with exposure duration. CONCLUSION Exposure to wood dust, even for short periods of time, incurs a risk of developing ITAC, usually after a long latency period. Any exposure requires lifetime follow-up, to ensure prompt treatment. Factors leading to the development of nasal ITAC and non-ITAC are probably different. The analogy with Barret's esophagus and esophageal adenocarcinoma may shed light on the oncogenesis of nasal ITAC.

Abstract
Intestinal-type adenocarcinoma is the second most frequent sinonasal adenocarcinoma. High incidence of these tumors is seen among workers with occupational wood dust exposure, particularly of hardwood dusts. Intestinal-type adenocarcinoma has striking histomorphologic and immunophenotypic similarities with colorectal adenocarcinomas, but on the level of molecular pathologic mechanisms these tumors have their own specific features different from gastrointestinal tumors. This article provides an update on current histopathologic classification of intestinal-type adenocarcinomas, their immunophenotypic properties, recent advances in molecular pathologic features and differential diagnostic considerations.
