Initial results of the oesophageal and gastric cancer registry from the Comunidad Valenciana. / Resultados iniciales del registro de carcinomas esófago-gástricos de la Comunidad Valenciana.

AIMS: To evaluate the initial results of the oesophagogastric cancer registry developed for the Sociedad Valenciana de Cirugía and the Health Department of the Comunidad Valenciana (Spain). METHODS: Fourteen of the 24 public hospitals belonging to the Comunidad Valenciana participated. All patients with diagnosis of oesophageal or gastric carcinomas operated from January 2013 to December 2014 were evaluated. Demographic, clinical and pathological data were analysed. RESULTS: Four hundred and thirty-four patients (120 oesophageal carcinomas and 314 gastric carcinomas) were included. Only two hospitals operated more than 10 patients with oesophageal cancer per year. Transthoracic oesophaguectomy was the most frequent approach (84.2%) in tumours localized within the oesophagus. A total gastrectomy was performed in 50.9% patients with gastroesophageal junction (GOJ) carcinomas. Postoperative 30-day and 90-day mortality were 8% and 11.6% in oesophageal carcinoma and 5.9 and 8.6% in gastric carcinoma. Before surgery, middle oesophagus carcinomas were treated mostly (76,5%) with chemoradiotherapy. On the contrary, lower oesophagus and GOJ carcinomas were treated preferably with chemotherapy alone (45.5 and 53.4%). Any neoadjuvant treatment was administered to 73.6% of gastric cancer patients. Half patients with oesophageal carcinoma or gastric carcinoma received no adjuvant treatment. CONCLUSIONS: This registry revealed that half patients with oesophageal cancer were operated in hospitals with less than 10 cases per year at the Comunidad Valenciana. Also, it detected capacity improvement for some clinical outcomes of oesophageal and gastric carcinomas.

Incidence and survival rates for malignant salivary gland tumors.

The aims of this study were to determine the incidence of malignant salivary gland tumors (MSGTs) in a specific in Spanish Mediterranean population, evaluate oncological outcomes, and identify prognostic factors for survival. Overall survival and disease-free survival rates were calculated for 23 patients with MSGTs who were treated in our department during 2004-2012. In the recruitment population of the reference hospital, annual incidence per 100,000 inhabitants was estimated, with corresponding 95% confidence intervals (CIs). The mean annual incidence of MSGTs was 0.91 new cases per 100,000 inhabitants (95% CI, 0.14-2.83). The most common histological type was squamous cell carcinoma (34.8%). Overall survival ranged from 2 to 120 months (mean 70.5 months). The 5-year overall survival rate was 52.5%, and the 5-year disease-free survival rate was 50%. The mean disease-free interval was 73.9 months (95% CI 47.1-100.7). Metastatic spread, tumor stage, perineural invasion, a submaxillary location, tumor size, histological grade, positive lymph node status, and presence of positive surgical resection margins were the most important factors in patient survival. Our results are consistent with those of other studies in relation to disease incidence but differ somewhat with respect to histological type. (J Oral Sci 58, 67-73, 2016).
