Introduction: The aim of this study was to analyze the clinical and genetic characteristics of young lung cancer cases, and to compare them with those of older cases., Methods: We used the Thoracic Tumors Registry (TTR) as a data source representative of lung cancer cases diagnosed in Spain, and included all cases registered until 9/01/2023 which had information on age at diagnosis or the data needed to calculate it. We performed a descriptive statistical analysis and fitted logistic regressions to analyze how different characteristics influenced being a younger lung cancer patient., Results: A total of 26,336 subjects were included. Lung cancer cases <50 years old had a higher probability of being women (OR: 1.38; 95% CI: 1.21-1.57), being in stage III or IV (OR: 1.32; 95% CI: 1.08-1.62), not having comorbidities (OR: 5.21; 95% CI: 4.59-5.91), presenting with symptoms at diagnosis (OR: 1.53; 95% CI: 1.29-1.81), and having ALK translocation (OR: 7.61; 95% CI: 1.25-46.32) and HER2 mutation (OR: 5.71; 95% CI: 1.34-24.33), compared with subjects ≥50 years. Among subjects <35 years old (n=61), our study observed a higher proportion of women (59.0% vs. 26.6%; p<0.001), never smokers (45.8% vs. 10.3%; p<0.001), no comorbidities (21.3% vs. 74.0%; p<0.001); ALK translocation (33.3% vs. 4.4%; p<0.001) and ROS1 mutation (14.3% vs. 2.3%; p=0.01), compared with subjects ≥35 years., Conclusions: Lung cancer displays differences by age at diagnosis which may have important implications for its clinical management., (Copyright © 2023 The Author(s).

Nasopharyngeal carcinoma is the predominant tumour type arising in the nasopharynx. Its aetiology is multifactorial; racial and geographical distribution, EBV infection and environmental exposure to specific substances are considered risk factors. This condition is endemic in some Asian areas, where a genetic predisposition in its oncogenesis has been established. There is a strong susceptibility between nasopharyngeal carcinoma and HLA, where related specific haplotypes have been found. In areas where the incidence is low, there are few reported cases of families affected. We report 3 cases of families with nasopharyngeal carcinoma among siblings, in the non-Asian population, probably related to EBV infection., (Copyright © 2016 Elsevier España, S.L.U. and Sociedad Española de Otorrinolaringología y Cirugía de Cabeza y Cuello.

Paragangliomas are rare tumors and most are benign: less than 10% show criteria for malignancy. In the head and neck, the main locations are carotid, jugulo-tympanic and vagal. Surgery continues to be the mainstay of treatment but both external beam radiotherapy (EBRT) and stereotactic radiosurgery (SRS) have been shown to be effective therapeutic alternatives. EBRT requires large volumes to cover the lesion, while radiosurgery allows administration of a high dose in a smaller volume, with high precision, which should reduce the number of long-term complications. The results in terms of local control with both treatment modalities are good, as reflected in published series. The role of chemotherapy is restricted to malignant paragangliomas. The treatment used includes the combination of chemotherapy, which provides short-lasting responses, and the role of new molecular targets is currently being investigated. The present article reviews the indications and results of the non-surgical treatment of paragangliomas.
