GARCIA M, Raimundo; FERNANDEZ G, Roberto y GONZALEZ E, Rubén. Epidemiology of lymphoma of the head and neck in the Centro Asistencial Sótero del Río. Rev. Otorrinolaringol. Cir. Cabeza Cuello [online]. 2011, vol.71, n.1, pp.23-30. ISSN 0718-4816. http://dx.doi.org/10.4067/S0718-48162011000100004.
Introduction: Lymphomas are the most common hematologic neoplasia in the adult and the third most common neoplasias of the head and neck (CyC). There are two types of lymphoma: Hodgkin and non-Hodgkin lymphomas, which constitute two unique clinical entities. Aim: To evaluate the clinical manifestations of lymphomas in the CyC region, analizing the diferences between the clinical presentation and behavior of LH and LNH. Material and method: This is an retrospective study of all the cases of lymphoma of CyC in the Centro Asistencial Dr. Sótero del Río (CASR) between the years 2005 and 2009, describing specifically the clinical presentation, risk factors, type of lymphoma, histologic diagnosis, anatomical localization, etapification at diagnosis, treatment received and survival. Results: Eighty cases of lymphoma of the CyC were included, 16 patients (20%) with LH and 64 patients (80%%) with LNH. We found statistically significant differences between both groups for their age at diagnosis, extranodal disease, mediastinal compromise, presence of "B" symptoms and survival. Conclusion: in the CASR the clinical presentation of lymphomas is similar to that reported in the international literature, maintaining the unique characteristics for LH and LNH.
