The objective of this study was to examine the trends in the pattern of occurrence of lip cancer in Madrid, Spain. Methods: Data were extracted from the Central Tumour Registry of Madrid, between 1990 and 2011. Variables examined were age, sex, topographic and morphological location and tumour histology. Two consecutive periods, 1990-2001 and 2002-2011, were studied by descriptive and analytical methods, and the data from the two periods were statistically compared. Results: A total of 881 cases were registered during the period 1990-2011. Comparing data between the two periods (1990-2001 and 2002-2011), subtle variations in age, histology and location were noted. Gender ratios remained constant. The mean age increased from 66.3 to 69.7 years (P < 0.05). In the second period, the histological distribution showed an increase in frequency of basal cell carcinoma, from 2.1% to 4.7%, while the frequency of squamous cell carcinomas remained constant. Basal cell carcinoma no longer predominantly occurred in women, decreasing from 80% to 21.1% (P < 0.001). The distribution by gender of squamous cell carcinoma had become more equal due an increase in its frequency in women (P < 0.001). Frequency of tumours on lip mucosa and commissure had increased between the two periods (P < 0.004). Conclusions: The pattern of lip cancer reported to Public Hospitals of Madrid is changing: declining rates are noted since 2001-02. However, it is necessary to monitor these data to confirm the observed trends in future years.
