Esophageal Cancer (EAC) and Esophageal Sarcoma (ESCC) in Canada
Since the mid-80s the rates of EAC have been increasing in Canada while ESCC has decreased. These opposite trends could be due to changing patterns of cigarette smoking and diet, or other factors.
The 5-year survival rate for patients with esophageal cancer is low (13 percent). The rate of survival varies based on morphology and the location of the tumour.
Risk Factors
Esophageal Cancer is the leading cause of cancer deaths around the world. In 2017, there were 604,000 new cases, and 544,000 deaths. About 70% of patients are men, canadian pacific Acute lymphocytic leukemia and they are more common among people who are older. The incidence and mortality rates vary by region. The highest rates are found in Eastern Asia (especially China) while the lowest levels are in Western sub-Saharan Africa.
Overall, the global age-standardised incidence, mortality and DALY rates for esophageal squamous cell carcinoma (ESCC) have been decreasing since 1990; however, this trend is not consistent across all countries/territories. These changes are partly the result of better treatment and detection, but also reflect the changing world environment, with an increase in exposure to alcohol and smoking tobacco.
Additionally, a variety of risk factors contribute to the development of esophageal adenocarcinoma (EAC). This includes an history of gastro-oesophageal disease, long-term smoking or alcohol use, heavy smoking and poor oral health; a diet deficient in fruits and vegetables; and being overweight. A genetic predisposition and Barrett's Esophagus can also be potential risk factors.
The esophageal cancer-specific DALY rate is calculated using the country-level incidence and prevalence rates and a weighting factor specific to the disease to calculate sequelae-specific disability (YLDs). For more details, see the Methodology Section of the Technical Report.
Diagnosis
The rate of incidence and survival of esophageal cancer are very low. In Canada the five-year relative survival is 13%. This is the lowest cancer-specific survival rate.
Esophageal cancers are classified into two categories: esophageal Squamous-cell carcinomas (ESCC) or esophageal cancers called adenocarcinomas. The tumors that are located within the upper portion of the esophagus could be classified as squamous-cell cancers, while those that are located in the lower part of the esophagus could be adenocarcinomas. A biopsy is typically needed to confirm the diagnosis. The procedure used for this is called an esophagogastroduodenoscopy. It involves passing a flexible, camera-equipped tube into the throat to look at the esophageal wall. The biopsy is taken from the lesion, and then tested for Canadian Pacific Acute Lymphocytic Leukemia malignancy.
Since the mid-1980s rates of Esophageal cancer have been stable in Canada, with EAC rates slightly higher than ESCC. Between 1986 and 2006, the incidence of EAC increased by two-thirds while ESCC declined by a third. The increase in the prevalence of EAC could be due to increases in gastroesophageal disease and obesity. Smoking cessation could be the reason for the decline in ESCC.
The frequency and duration of survival vary across the country based on the morphology of the tumor and location in the anatomical factors. For example, EAC rates have increased significantly in British Columbia, Ontario and Quebec, while ESCC rates have decreased.
Treatment
The cancer is usually found in the outer layer (squamous-cell carcinoma) or in the muscle and connective tissues in the interior (esophageal-squamous cancer). These cancers are often cured by surgery. If the cancer has spread to adjacent lymph nodes and tissues, it can be more difficult to treat. Endoscopic ablation and radiation therapy are two options for those suffering from stage II esophageal cancer. They also require regular follow-up by endoscopy to check for any indications of cancer returning.
Chemotherapy makes use of drugs to kill cancer cells or stop them from growing. The drugs can either be administered orally or directly into a muscle, vein or vein. They can be administered without or with radiation. When chemotherapy is given with radiation, it is called chemotherapy therapy.
To keep the esophagus in a closed position during radiation therapy, a tube of plastic can be placed. This is referred to as a gastostomy tube. It is important to keep the esophagus clear because swallowing may help stop pneumonia from occurring.
Targeted therapy uses medicines that target specific cancerous cells and decrease the side effects of radiation or chemotherapy therapy. These drugs could include monoclonal antibodies as well as other drugs. There are currently clinical trials being conducted to find new treatments for cancers of the esophagus.
