Symptoms and Late Diagnosis

Dr. Jari Rasanen, MD, identifies the primary symptoms of esophageal carcinoma. These include difficulty swallowing food and sometimes pain. A critical challenge in esophageal cancer is that these symptoms typically emerge at a very late stage of the disease. This late presentation significantly complicates treatment and impacts patient prognosis.

Demographics and Risk Factors

Dr. Jari Rasanen, MD, discusses the typical patient profile for esophageal carcinoma. The disease is frequently diagnosed at advanced stages due to the nature of its symptoms. During his discussion with Dr. Anton Titov, MD, he notes that certain populations with chronic esophageal inflammation require vigilant monitoring. These high-risk patients should undergo regular gastroscopies to facilitate early cancer detection.

Western vs Eastern Risk Factors

Dr. Jari Rasanen, MD, highlights a major epidemiological distinction in esophageal cancer. He explains that risk factors differ drastically between Western and Eastern countries. In Western populations, esophageal cancer is strongly linked to obesity and the resulting gastric reflux disease. Conversely, in Eastern countries, the predominant risks are behavioral, including the consumption of hot beverages, tobacco smoking, and alcohol use. Genetic differences between populations may also contribute to these observed patterns.

Histological Types and Location

The histological type of esophageal cancer also varies by region, as detailed by Dr. Jari Rasanen, MD. Squamous cell carcinoma is more common in Eastern countries and can be found throughout the esophagus, though it frequently appears in the middle and upper parts. Adenocarcinoma is the predominant type in Western nations. Dr. Rasanen specifies that adenocarcinoma is almost always located in the distal part of the esophagus, near the stomach.

Importance of Early Detection

Dr. Jari Rasanen, MD, concludes with a vital recommendation for patient care. Because symptoms manifest late, proactive screening is essential. He stresses that individuals with chronic inflammation of the esophageal mucosa must be followed with regular gastroscopies. This surveillance strategy is the most effective method for identifying esophageal carcinoma at an early, more treatable stage, ultimately improving patient outcomes.

Dr. Anton Titov, MD: What are the symptoms of esophageal carcinoma? And what are the typical patient demographics at diagnosis? The age, particular risk factors, because we know that esophageal carcinoma is diagnosed at late stages frequently. That's the problem.

Dr. Jari Rasanen, MD: Usually the patients will get the symptoms at a very late stage of the esophageal cancer. Common symptoms are difficulties in swallowing your food. Some pain problems can be there. But very often when you get the symptoms, it is rather late stage of disease already.

Dr. Jari Rasanen, MD: Therefore, if a patient has some chronic inflammation in his esophageal mucosa, he or she should be followed up with gastroscopies. Then you could find possible esophageal cancer in the early stages.

Dr. Anton Titov, MD: There are some countries with particular risk factors for esophageal carcinoma, where esophageal carcinoma happens more often. Is it hot drinks, particular alcohol, or smoking or anything else that is a risk for esophageal cancer?

Dr. Jari Rasanen, MD: There is a significant difference between the types of esophageal cancer in Western and Eastern countries. In Western countries, esophageal cancer is related to gastric reflux disease. Gastric reflux, on the other hand, is related to obesity. So, basically obesity and reflux disease are the most important risk factors in Western countries.

Dr. Jari Rasanen, MD: On the other hand, in the Eastern countries, the type of esophageal cancer is more often squamous cell carcinoma. Esophageal cancer risk is more related to hot beverages, tobacco smoking, and alcohol consumption. There are certainly some genetic differences between western and eastern countries, which can also explain the epidemiological differences.

Dr. Anton Titov, MD: Does the location of his esophageal cancer differ from eastern and western countries depending on the histological type of esophageal cancer?

Dr. Jari Rasanen, MD: Yes, it does, because squamous cell carcinoma basically can be found everywhere in the esophagus, but it is more common in the middle and upper part of the esophagus. On the other hand, adenocarcinoma, which is more common in Western countries, it's almost always in the distal part of the esophagus.
