Abstract

Patients seeking healthcare in medically underserved regions often require travel to larger metropolitan hubs across the state of Texas. The Rio Grande Valley (RGV) is home to many such patients who often travel to central Texas for care, which compounds expense and inconvenience. Pockets of central Texas have been reported to have an increased number of dermatologists per 100,000 people. Bexar county ranks among the five most populous counties in the state, with increased access to dermatologic care compared to nearby regions. Using data from the Texas Cancer Registry, this project aims to identify the mean (M) age of diagnosis for skin carcinomas between 1995-2019 in Hispanic and non-Hispanic individuals. The primary code used to identify these skin carcinomas on the TCR database was "Site recode ICD-O-3/WHO 2008," which included 27 different non-epithelial skin cancers, including Merkel cell carcinoma and sebaceous adenocarcinoma. It is important to note that the TCR considers common primary skin cancers, such as basal and squamous cell carcinoma coded as C44.0-C44.9, as non-reportable. Once collected, the M values will be compared and contrasted between both Bexar and the remaining counties in Texas using a two sample t-test, assuming unequal variances. In the same manner, we aim to compare Bexar and its seven neighboring counties to the four counties that comprise the RGV. The primary hypothesis is that the mean age of diagnosis for skin carcinomas in Bexar county is lower than the remainder of Texas for the two studied race groups: spanish-hispanic-latino (SHL) and non-spanish-hispanic-latino (nSHL) patients. The second hypothesis is that the eight previously selected central Texas counties have a lower mean age of diagnosis for skin carcinomas for all patients, regardless of race, when compared to the RGV. The results pertaining to the primary hypothesis did not convey a statistically significant difference in the mean diagnostic age for SHL patients (Bexar, M= 68.3, SD=16; Texas, M= 66.9, SD= 15.2; t(130)= 0.736, p= 0.462). Likewise, there was no statistically significant result for nSHL patients (Bexar, M = 70.9, SD=15; Texas, M= 71.2, SD 13.6; t(200)= -0.276, p= 0.782). Accounting for Bexar and its seven surrounding counties (Central Texas), when compared to the remainder of Texas (ROT), there was no statistically significant difference in the mean diagnostic age for SHL patients (Central Texas, M= 67.8, SD= 15.6; ROT, M= 67.1, SD= 15.33; t(162), p= 0.632). These results remained true for nSHL patients (Central Texas, M= 70.9, SD= 14.5; ROT, M= 71.2, SD= 13.6; t(274), p= 0.73). Finally, the results pertaining to the second hypothesis did not convey a significant difference in the mean diagnostic age between central Texas and the RGV (Central Texas, M= 69.9, SD= 14.9; RGV, M= 71.8, SD= 14.5; t(312)= 1.38, p= 0.167).

An Analysis of the Diagnostic Age of Skin Carcinomas Across Central Texas

Patients seeking healthcare in medically underserved regions often require travel to larger metropolitan hubs across the state of Texas.
