Esophageal Cancer (EAC) and Esophageal Sarcoma (ESCC) in Canada
Since the mid 1980s the rates of EAC have been increasing in Canada while ESCC has been declining. These opposing trends may be due to changes in cigarette smoking, diet or other factors.
The 5-year survival rate for patients diagnosed with esophageal cancer is very low (13%). The rates vary depending on the morphology of the cancer and location.
Risk Factors
Esophageal cancer is a leading cause of cancer death worldwide with more than 604,000 newly diagnosed cases and 544,000 deaths in 2017. About 70 percent of cases occur in men and are more common in older people. The incidence and mortality rates vary according to region. The highest rates are in Eastern Asia (especially China) while the lowest rates are found 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 largely the result of better diagnosis and treatment, but also reflect the changing global environment which has increasing exposure to alcohol and Canadian Pacific Black Lung Disease tobacco smoking.
In addition, a number of risk factors are associated with the development of esophageal canadian pacific stomach cancer (EAC). Some of them include an underlying gastro-oesophageal disease smoking, drinking alcohol, smoking or chewing tobacco in excess and having poor oral hygiene an inadequate diet of vegetables and fruits, as well as being overweight. Other risk factors that could lead to EAC include a genetic predisposition and the presence Barrett's esophagus.
The esophageal cancer-specific DALY rate is calculated using the country-wide incidence and prevalence rates and a weighting factor specific to the canadian pacific chronic obstructive pulmonary disease canadian pacific mesothelioma black lung disease [website] to estimate sequelae-specific impairment (YLDs). For more information, please refer to 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 comparative survival rate is 13 percent. This is the lowest survival rate.
Esophageal cancers fall into two categories: esophageal-squamous-cell carcinomas (ESCC) or esophageal Adenocarcinomas. Tumors that are located in the upper portion of the esophagus could be classified as squamous cell carcinomas and those located in the lower part of the esophagus are adenocarcinomas. A biopsy is often required to confirm the diagnosis. The procedure used for this is called an esophagogastroduodenoscopy. It involves using a flexible tube that has an illuminated camera and a light down the throat to examine the wall of the esophageal. The biopsy is then taken from the lesion and tested for malignancy.
Since the mid-1980s, rates of esophageal carcinoma have been stable in Canada in Canada, with EAC rates slightly higher than ESCC. Between 1986 and 2006 the incidence of EAC increased by two-thirds while ESCC decreased by a third. The rise in EAC could be due to obesity and gastroesophageal reflux disease. Smoking cessation may be the cause of the decline in ESCC.
The frequency and duration of survival vary across the country based on the morphology of the tumour, anatomical location and other factors. For instance, the rates of EAC have significantly increased in British Columbia and Ontario, however, Canadian pacific Stomach cancer (https://Adminwiki.Legendsofaria.com) the rates for ESCC have declined there.
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 types of cancers are usually able to be treated surgically. It is more difficult for the cancer to be cured when it has spread to nearby lymph nodes and tissues. Patients with stage II esophageal cancer can be treated using endoscopic ablation or radiation therapy. They also require a close follow-up by using endoscopy in order to detect any signs of cancer coming back.
Chemotherapy is the process of using medications to stop cancer cells from growing or kill them. The drugs can be consumed by mouth or in a vein or muscle. They can be administered without or with radiation. If chemotherapy is administered with radiation, it is known as chemotherapy therapy.
A tube made of plastic may be placed into the esophagus in order to keep it open during radiation treatment. This is referred to as a gastropharyngeal tube. It is important to keep your esophagus in order to help prevent pneumonia.
Targeted therapies use medicines to target specific cancer cells and minimize the side negative effects of radiation therapy. These drugs could comprise monoclonal antibody and other medications. There are currently clinical trials being conducted to discover new treatments for cancers of the esophagus.
