Background: According to GLOBOCAN estimates, in 2020, lung cancer was the second most frequent cancer and epidemiological information is needed in Latin American countries. The objective was to describe the epidemiological and molecular characteristics of lung cancer patients from a referral clinic in Lima, Peru. Material and methods: A retrospective cohort study was conducted to characterize the epidemiological and molecular profile of lung cancer patients attended at a referral cancer center in Peru during 2018 to 2021. Variables such as age, sex, histology, staging and mutation were reported. In the descriptive analysis, frequencies and percentages were shown for categorical variables. For numerical variables, the best measure of central tendency and dispersion was reported. Results: A total of 225 patients with a diagnosis of lung cancer were observed. EGFR gene mutation was the most...

Peru reported the second-highest COVID-19 cases in Latin America, after Brazil. The first COVID-19 wave occurred between March–December 2020, and the second occurred between January–September 2021. The differences between these waves remain largely unknown, and there is no comparison between them in Peru. We evaluated the variation in the clinical and epidemiological components of COVID-19-affected patients in both waves in northern Peru by a retrospective study using the clinical follow-up database of Lambayeque and the epidemiological notification form database of NotiWeb. The COVID-19-associated factors during the two waves were determined using simple and multiple regression analysis, and the prevalence ratio (PR) was estimated. During the second wave of COVID-19, there was an increase in cough symptoms in 12.1%, odynophagia in 5.0%, and chills in 16.0% compared with the first wa...
