Researchers, led by Marquita W. Lewis-Thames, PhD, MPH, MS, conducted a cross-sectional study of the <a href="https://seer.cancer.gov/">Surveillance, Epidemiology, and End Results</a> (SEER) database in order to describe the &ldquo;rural-urban trends&rdquo; in five-year lung, prostate, breast, and colorectal cancer-specific survival. After their analyses, researchers concluded that, &ldquo;even after accounting for sociodemographic and tumor characteristics, these findings suggest that non-Hispanic Black patients with cancer are particularly vulnerable to cancer burden, and resources are urgently needed to reverse decades-old survival trends.&rdquo;According to the article in&nbsp;JAMA Network Open, the study&rsquo;s authors analyzed patients from the SEER database who were diagnosed no later than 2011. Participants&rsquo; rural or urban status was based on the 2013 Rural-Urban Continuum Codes. Cox, linear regression, and joinpoint regression models were used to calculate the cancer-specific survival rates for rural and urban individuals.<h2>Findings on Rural-Urban Cancer Survival in the SEER Database</h2>Overall, the analysis included 3,659,417 patients with cancer (1,918,609 [52.4%] male; 237,815 [6.5%] Hispanic patients; 396,790 [10.8%] Black patients; and 2,825,037 [77.2%] White patients). Among the subjects, 888,338 patients had lung cancer (24.3%), 750,704 patients had colorectal cancer (20.5%), 987,826 patients with breast cancer (27.0%), and 1,023,549 patients with prostate cancer (28.0%). Overall, 430,353 patients were rural.Investigators found that, in general, &ldquo;rural patients were likely to be non-Hispanic White individuals, have more cases of distant tumors, and be older,&rdquo; and, furthermore, &ldquo;rural and non-Hispanic Black patients for all cancer types often had shorter survival.&rdquo; Specifically, five-year lung cancer survival was &ldquo;shorter for non-Hispanic Black rural patients in 1975 at 48%, while increasing to 57% for both non-Hispanic Black urban and rural patients in 2011, but still the shortest among all cancer types.&rdquo;Ultimately, &ldquo;although the probability of survival increased during the observed time, rarely did the differences between urban and rural patients narrow,&rdquo; according to the results, and the investigators reinforced the need for measures to address the &ldquo;36-year&rdquo; discrepancy in urban and rural cancer survival probability.Find More <a href="https://www.docwirenews.com/latest-hematology-oncology-news-2/">Related Research, Expert Interviews, and Cancer News</a>
