    Abstract:
    UNLABELLED: There was a significant change in the histology of oesophageal cancers in the last few decades. The incidence of oesophageal adenocarcinoma has risen considerably, now it is equally or even more prevalent than squamous cell cancers in some North American and Western European countries. As no Hungarian data is available, the authors' aim was to investigate the prevalence and histology of oesophageal and gastrooesophageal junction cancers in the last decade. PATIENTS AND METHODS: 451 patients diagnosed with oesophageal (n = 371, 296 male/75 female, mean age at diagnosis: 57.9 SD 10.1 years) or cardia (n = 80, 58 male/22 female, mean age at diagnosis: 65.2 SD 13.4 years) cancer between 1st of January 1993 and 31st of December 2003 at the 1st Internal Medicine and 1st Surgery Department of Semmelweis University were enrolled. Pathology and clinical data were analysed retrospectively. RESULTS: 93% (n = 345) of the patients with oesophageal cancer had squamous cell carcinomas, while adenocarcinoma was only diagnosed in 15 (4%) patients. Mean age at diagnosis was lower in patients with squamous cell cancer (57.4 SD 10.0 years) compared to patients with adenocarcinoma (66.9 SD 8.8 years, p = 0.001). Male-to-female ratio was 4:1 in patients with squamous cell carcinoma (277/68) and undifferentiated carcinoma (9/2), while it was 2:1 in patients with adenocarcinoma (10/5). According to the location 1.3% of cancers of the midthoracic oesophagus and 8.6% of the lower oesophagus were adenocarcinoma. The proportion of adenocarcinoma remained stable over the observed period (1993-1997: 3.7% vs. 1998-2003: 4.3%). In contrast, 71.25% (57/80) of the gastrooesophageal junction cancers and overall 15.9% (72/451) of the cancers of the oesophagus and gastrooesophageal junction were adenocarcinoma (1993-1997: 17.2% vs. 1998-2003: 14.7%). CONCLUSIONS: Since only a few percentages of authors patients with oesophageal cancers were diagnosed to have adenocarcinoma and its proportion remained stable over the observed period, it seems that in contrast to North American and Western European countries, adenocarcinoma is still infrequent in Hungary.
