Esophageal Cancer Screening (PDQ®): Screening - Health Professional Information [NCI] - Significance

Natural History, Incidence, and Mortality

In 2013, it is estimated that 17,990 Americans will be diagnosed with esophageal cancer, and 15,210 will die of this malignancy.[1] Of the new cases, it is estimated that 14,440 will occur in men and 3,550 will occur in women.

Overview

This complementary and alternative medicine (CAM) information summary provides an overview of the use of PC-SPES as a treatment in people with cancer. The summary includes a brief history of PC-SPES research, the results of clinical trials, and possible adverse effects of PC-SPES. Included in this summary is a discussion of the contamination of PC-SPES and its withdrawal from avenues of distribution. This summary contains the following key information: PC-SPES is a patented mixture of eight...

Two histologic types account for the majority of malignant esophageal neoplasms: adenocarcinoma and squamous carcinoma. The epidemiology of these types varies markedly. In the 1960s, squamous cell cancers comprised more than 90% of all esophageal tumors. The incidence of esophageal adenocarcinomas has risen considerably for the past 2 decades, such that it is now more prevalent than squamous cell cancer in the United States and Western Europe, with most tumors located in the distal esophagus.[2] Although the overall incidence of squamous cell carcinoma of the esophagus is declining, this histologic type remains six times more likely to occur in black males than in white males.[3] Incidence rates generally increase with age in all racial/ethnic groups but squamous cell cancer is consistently more common in blacks than in whites. Among black men, the incidence rate for those aged 55 to 69 years is close to that of white men aged 70 years and older. In black women aged 55 to 69 years, the incidence rate is slightly higher than white women aged 70 years and older.

Risk Factors

While risk factors for squamous cell carcinoma of the esophagus have been identified (such as tobacco, alcoholism, malnutrition, and infection with human papillomavirus),[4] the risk factors associated with esophageal adenocarcinoma are less defined. The most important epidemiological difference between squamous cell cancer and adenocarcinoma, however, is the strong association between gastroesophageal reflux disease (GERD) and adenocarcinoma. The results of a population-based case-controlled study suggest that symptomatic gastroesophageal reflux is a risk factor for esophageal adenocarcinoma. The frequency, severity, and duration of reflux symptoms were positively associated with increased risk of esophageal adenocarcinoma.[5,6,7]

Long-standing GERD predisposes to Barrett esophagus, the condition in which an abnormal intestinal epithelium replaces the stratified squamous epithelium that normally lines the distal esophagus.[8] The intestinal-type epithelium of Barrett esophagus has a characteristic endoscopic appearance that differs from squamous epithelium.[9] Dysplasia in Barrett epithelium represents an alteration of the columnar epithelium that may progress to invasive adenocarcinoma.[10]
