My name is Leonardo Lino-Silva, I am a pathologist with high speciality in oncology, also I have one doctorate and actually I am the head of Division of Sutrgical Pathology of the National Cancer Institute (Mexico). During my training as a specialist, I developed a keen interest in research, collaborating with various institutions and experienced researchers. This led me to pursue an MSc and then a PhD, focusing on neoplasms in our population, particularly thyroid gland, melanoma, and gastrointestinal (GI) cancer. A significant achievement was the characterization of the micropapillary (hobnail) variant of papillary thyroid carcinoma. Our research revealed critical epidemiological differences in cancer subtypes compared to other populations; for instance, our patients often present with more advanced stages of thyroid cancer, with nearly half categorized as high-risk. We observed a greater prevalence of diffuse gastric carcinoma and more acral and nodular melanomas than lentiginous and superficial spreading types. Additionally, there is a higher microsatellite instability (MSI) in colorectal cancer. These findings suggest unique factors influencing carcinogenesis in our population beyond traditional models. For the past five years, I have also developed a fellowship in oncological pathology at the National Cancer Institute of Mexico, emphasizing quality education and research. This program not only trains Mexican specialists but also attracts trainees from other Latin American countries. Furthermore, I teach pathology at the National Autonomous University of Mexico, integrating problem-solving and research induction into the curriculum. Today, I am proud to say that I have published a total of 124 papers in reputable journals, boasting an impressive average impact factor of 3.5. Of my published works, 65% are as the first author or the corresponding author, showcasing my significant contributions to the field. I have also delivered more than 100 presentations at various conferences, further disseminating my research findings. Additionally, my work has garnered over 1,500 citations, reflecting the impact and relevance of my research within the scientific community. My H-index stands at 19, indicating my consistent and influential contributions to academic literature. Additionally, I have published three editorial pieces in prominent medical journals focusing on gastrointestinal pathology and lymphomas. My experience in manuscript review is extensive, having reviewed hundreds of submissions for various academic journals. Furthermore, I am honored to serve as an associate editor for esteemed publishing groups such as Baishideng Publishing Group and BMC Group. These experiences have allowed me to make significant contributions to advancing knowledge in my field, as well as to collaborate with fellow researchers and professionals within the medical community. My research spans cancer epidemiology, gastrointestinal oncology, melanoma, and tumor histopathology. In cancer epidemiology, I contributed to studies highlighting unique factors in young colorectal cancer patients, including advanced diagnoses and poor prognoses. We also characterized maxillary sinus sarcomas and prostate cancer, where we found that 18.9% of patients showed seminal vesicle invasion and noted an increase in papillary thyroid surgeries for tumors smaller than 3 cm. In gastrointestinal oncology, my focus shifted to rectal cancer, identifying mesorectal extension depth as a vital prognostic indicator and extramural perineural invasion as critical for survival in T3-T4 patients. We further investigated the prognostic implications of various histological features in colorectal and gastric cancers and published a review of Barrett's Esophagus. Within melanoma research, I explored clinicopathologic features and mutation profiles, finding that Mexican patients face worse outcomes than their U.S. counterparts. We established the prevalence of the BRAFV600E mutation and assessed the prognostic significance of the neutrophil-to-lymphocyte ratio, while emphasizing the critical need to recognize micropapillary carcinoma due to its associated poor prognosis. I possess a robust background in cancer research and epidemiology, with a particular focus on gastrointestinal oncology, melanoma, and tumor histopathology. My work has contributed to understanding distinct features of various cancers, such as advanced diagnoses in young colorectal cancer patients and the clinical characteristics of maxillary sinus sarcomas and prostate cancer. I have identified key prognostic factors, including mesorectal extension depth in rectal cancer and the significance of extramural perineural invasion for survival. In melanoma research, I analyzed clinicopathologic features and mutation profiles, noting worse prognoses among Mexican patients and emphasizing the prevalence of the BRAFV600E mutation. My expertise extends to the histopathologic characteristics of tumors, where I highlighted the importance of recognizing micropapillary carcinoma due to its association with poor outcomes. Additionally, I am passionate about running and trail sports, which reflects my commitment to personal health and endurance. I also enjoy exploring everyday life themes through movies and podcasts, enriching my perspective on various professions and trades.
