In Memoriam: Pelayo Correa (1927–2025)
Translate Article 
Take Notes Pelayo Correa, born in Sonsón, Antioquia, in 1927, was one of the most influential figures in cancer epidemiology and pathology in Latin America and worldwide. His work transformed the understanding of gastric carcinogenesis and gave rise to one of the most solid and longstanding population-based registries on the continent. His scientific life - defined by rigor, curiosity, and public service - leaves an enduring legacy for generations of researchers. Professor Correa graduated as a physician from the University of Antioquia in 1949, where he completed his thesis on cancer statistics in the department —pioneering work that sparked his lifelong interest in differences in cancer risk across populations. This early study took him to Emory University in the United States, where he trained as a pathologist and solidified his etiologic vocation: to understand the causes of disease, not only its morphological expression. After completing his training, he returned to Colombia and joined the Universidad del Valle. During a 1961 congress, his presentation on cancer patterns in Cali drew the attention of Dr. Harold Stewart of the National Cancer Institute (NCI), who shared the data with Dr. William Haenszel. From that exchange, Dr. Haenszel traveled to Cali and, together with Professor Correa, helped establish the Cali Population-Based Cancer Registry (RPCC), the first in Latin America and today one of the oldest in the world. Dr. Haenszel also served as his mentor in epidemiology, contributing to the design and conduct of the investigations that followed in subsequent decades, aimed at clarifying the determinants of gastric cancer. The strength of the Cali Registry became evident early on. The RPCC publication in the Journal of the National Cancer Institute in April 1966 coincided with the release of the first volume of Cancer Incidence in Five Continents(January 1966), which included RPCC data. This convergence placed the Cali registry within the foundational landmarks of global cancer surveillance. At a time when the world was beginning to standardize comparative incidence measurement, Professor Correa’s work provided rigorous data from Latin America, demonstrating that his epidemiological vision was not only aligned with global developments but contributed to them from the outset.

Despite steady decreases in the cancer burden in industrialized countries, its rapid increase in the developing world means that the number of cancer cases and deaths will likely more than double worldwide over the next two decades ([1][1]). Already a leading cause of death around the globe, cancer

BACKGROUND AND OBJECTIVES:Despite its relatively low incidence in Saudi Arabia, breast cancer has been the most common cancer among Saudi females for the past 12 consecutive years. The objective of this study was to report the results of the first national public breast cancer screening program in Saudi Arabia.METHODS:Women 40 years of age or older underwent breast cancer screening. Mammograms were scored using the Breast Imaging-Reporting and Data System (BI-RADS). Correlations between imaging findings, risk factors and pathological findings were analyzed.RESULTS:Between September 2007 and April 2008, 1215 women were enrolled. The median age was 45 years, and median body mass index was 31.6 kg/m2. Sixteen cases of cancer were diagnosed. No cancer was diagnosed in 942 women with R1/R2 scores, and only 1 case of cancer was diagnosed in 228 women with R0/R3 scores. However, among 26 women with R4/R5 scores, 50% had malignant disease and 35% had benign lesions. No correlation was found between known risk factors and imaging score or cancer diagnosis.CONCLUSIONS:Public acceptance of the breast cancer screening program was encouraging. Longitudinal follow-up will help in better determining the risk factors relevant to our patient population.
