ABSTRACT
The study of the increasing incidence of melanoma over the past few decades is essential regarding prevention and optimization of health resources. We collected cases of melanoma from Hospital son Llàtzer from the Migjorn health sector of Mallorca, Spain from 2003 through 2021, and calculated the incidence of melanoma adjusted to the standard European population. In addition, other demographic and clinicopathological data were descriptively analyzed too. A total of 690 new cases of melanoma were detected with a progressive increase in the age-standardized incidence from 7.47 cases per 100,000 inhabitants/year in 2003 up to 23.84 in 2021 mainly due to early stages of the disease. The incidence of melanoma has increased significantly in Mallorca probably due to the increasing population coming from northern Europe (low phototypes), sun exposure habits (tourism, fishing, agriculture), and improved early diagnosis.

ABSTRACT
INTRODUCTION: The aim of this study was to establish the value of thalium-(201) single-photon emission computed tomography ((201)Tl-SPECT) in the detection of recurrences in the follow-up of patients with treated primary neuroepithelial tumours. MATERIAL AND METHODS: Sixty-three (201)Tl-SPECT were performed in 36 patients with glioma (12 males, mean age of 46 +/- 13 years). All patients underwent surgery and adjuvant radiotherapy (and some of them received chemotherapy). All patients were submitted to morphological neuroimaging techniques as well (and (201) Tl-SPECT). Mean follow-up was 18.3 +/- 14.6 months. Gold standard was based on clinical follow-up, therapeutical decisions (at least 4 months after (201)Tl-SPECT) and imaging features. RESULTS: Sensitivity and specificity of (201)Tl-SPECT to detect glioma recurrences were 90% and 100% respectively and 93% accuracy. Sensitivity and specificity for high grade tumours, were 100% respectively. Due to 4 false negatives, sensitivity and specificity for low grade gliomas were 78% and 100%. In the positive (201)Tl-SPECT group of patients overall survival was 13.64% at the end of the study. The negative (201)Tl-SPECT group had 84.62% overall survival at the end of the study (p = 0.0003). CONCLUSIONS. (201)Tl-SPECT is a valuable and noninvasive diagnostic procedure to detect recurrence or progression disease for treated gliomas and ependymomas. (201)Tl-SPECT has a good correlation with short term prognosis with excellent diagnostic accuracy (AU)
