RESUMO
Esophagogastric cancers are among the most common and deadly cancers worldwide. This review traces their chronology from 3000 BCE to the present. The first several thousand years were devoted to palliation, before advances in operative technique and technology led to the first curative surgery in 1913. Systemic therapies were introduced in 1910, and radiotherapy shortly thereafter. Operative technique improved massively over the 20th century, with operative mortality rates reducing from over 50% in 1933 to less than 5% by 1981. In addition to important roles in palliation, endoscopy became a key nonsurgical curative option for patients with limited-stage disease by the 1990s. The first nonrandomized studies on combination therapies (chemotherapy ± radiation ± surgery) were reported in the early 1980s, with survival benefit only for subsets of patients. Randomized trials over the next decades had similar overall results, with increasing nuance. Disparate conclusions led to regional variation in global practice. Starting with the first FDA approval in 2017, multiple immunotherapies now encompass more indications and earlier lines of therapy. As standards of care incorporate these effective yet expensive therapies, care must be given to disparities and methods for increasing access.
RESUMO
BACKGROUND: The incidence of reactions to epinephrine-containing local anesthetics in Mohs micrographic surgery (MMS) has not been established. OBJECTIVE: To estimate the incidence of epinephrine-induced reactions from local anesthetics in patients who undergo MMS for the removal of cutaneous malignancies. METHODS: From 2016 to 2018, 200 MMS patients were recruited from the authors' surgical center. Assessments were obtained throughout the entirety of the Mohs cases during a single visit. RESULTS: This study estimated the incidence of epinephrine reactions in patients who undergo MMS to be 2.0% (95% confidence interval: 0.1%-3.9%). No relationship between epinephrine dose and incidence of adverse effects was found. Patient age was a significant risk factor for the development of an epinephrine reaction. CONCLUSION: Systemic reactions to epinephrine from local anesthetics are an infrequent adverse event in MMS cases. The data suggest that the absolute dose of local anesthetic with epinephrine does not correlate with the risk of developing an epinephrine reaction. Older age seems to have a protective effect.
