Two histologic types account for the majority of malignant esophageal neoplasms: adenocarcinoma and squamous cell carcinoma. Adenocarcinomas typically start in the lower esophagus and squamous cell carcinoma can develop throughout the esophagus.

Oral cancer can develop in any part of the mouth, including the lips, gums, tongue, cheeks, and roof and floor of the mouth. Most cases of oral cancer are linked to tobacco use, heavy alcohol use, or infection with human papillomavirus HPV. Many oral cancers are detected by dentists through routine dental-hygiene procedures, and individuals should receive an oral examination at least annually.

Oral and dental health in head and neck cancer survivors

Two histologic types account for the majority of malignant esophageal neoplasms: adenocarcinoma and squamous cell carcinoma. Adenocarcinomas typically start in the lower esophagus and squamous cell carcinoma can develop throughout the esophagus.

The epidemiology of these types varies markedly. Estimated new cases and deaths from esophageal cancer in the United States in [ 1 ]. The incidence of esophageal cancer has risen in recent decades, coinciding with a shift in histologic type and primary tumor location. In the United States, squamous cell carcinoma has historically been more prevalent although the incidence of adenocarcinoma has risen dramatically in the last few decades in the United States and western Europe. The cause for the rising incidence and demographic alterations is unknown.

Enlarge The esophagus and stomach are part of the upper gastrointestinal digestive system. The esophagus serves as a conduit to the gastrointestinal tract for food. The esophagus extends from the larynx to the stomach and lies in the posterior mediastinum within the thorax near the lung pleura, peritoneum, pericardium, and diaphragm. As it travels into the abdominal cavity, the esophagus makes an abrupt turn and enters the stomach.

The esophagus is the most muscular segment of the gastrointestinal system and is composed of inner circular and outer longitudinal muscle layers. The upper and lower esophagus are controlled by the sphincter function of the cricopharyngeus muscle and gastroesophageal sphincter, respectively. The esophagus has a rich network of lymphatic channels concentrated in the lamina propria and submucosa, which drains longitudinally along the submucosa. Tumors of the esophagus are conventionally described in terms of distance of the upper border of the tumor to the incisors.

When measured from the incisors via endoscopy, the esophagus extends approximately 30 to 40 cm. The esophagus is divided into four main segments:. Risk factors associated with esophageal adenocarcinoma are less clear. Chronic reflux is considered the predominant cause of Barrett metaplasia. The results of a population-based, case-controlled study from Sweden strongly suggest that symptomatic gastroesophageal reflux is a risk factor for esophageal adenocarcinoma.

The frequency, severity, and duration of reflux symptoms were positively correlated with increased risk of esophageal adenocarcinoma. Patients with severe dysplasia in distal esophageal Barrett mucosa often have in situ or invasive cancer within the dysplastic area.

After resection, these patients usually have excellent prognoses. In most cases, esophageal cancer is a treatable disease, but it is rarely curable. The occasional patient with very early disease has a better chance of survival. Other PDQ summaries containing information related to esophageal cancer include the following:. For information about gastrointestinal stromal tumors, which can occur in the esophagus and are usually benign, refer to the following summary:.

For information about supportive care for patients with esophageal cancer, refer to the following summaries:. Barrett esophagus contains glandular epithelium cephalad to the esophagogastric junction. Gastrointestinal stromal tumors can occur in the esophagus and are usually benign. One of the major difficulties in allocating and comparing treatment modalities for patients with esophageal cancer is the lack of precise preoperative staging.

The stage determines whether the intent of the therapeutic approach will be curative or palliative. Endoscopic ultrasound-guided FNA for lymph node staging is under prospective evaluation. Thoracoscopy and laparoscopy have been used in esophageal cancer staging at some surgical centers. Noninvasive PET scan using the radiolabeled glucose analog fluorine F fludeoxyglucose 18F-FDG for preoperative staging of esophageal cancer is more sensitive than a CT scan or endoscopic ultrasound in detection of distant metastases.

A recent study of patients with potentially resectable esophageal cancer demonstrated the utility of 18F-FDG PET in identifying confirmed distant metastatic disease in at least 4. The AJCC has designated staging by TNM tumor, node, metastasis classification to define cancer of the esophagus and esophagogastric junction. Tumors with the epicenter of the tumor located in the gastric cardia beyond 5 cm of the gastroesophageal junction or without extension into the esophagus are classified as gastric cancer.

The classification of involved abdominal lymph nodes as M1 disease is controversial. The presence of positive abdominal lymph nodes does not appear to have a prognosis as grave as that for metastases to distant organs. Complete resection of the primary tumor and appropriate lymphadenectomy is attempted when possible. Use our advanced clinical trial search to find NCI-supported cancer clinical trials that are now enrolling patients. The search can be narrowed by location of the trial, type of treatment, name of the drug, and other criteria.

General information about clinical trials is also available. For patients with minimally invasive resectable esophageal cancer, surgical resection alone offers the potential for cure.

In contrast, therapeutic management for patients with locally advanced resectable esophageal cancer has evolved significantly over the last few decades. Because of the risk of distant metastases and local relapse, multimodality therapy with integration of chemotherapy, radiation therapy, and surgical resection has become the standard of care. Combined modality therapies are under clinical evaluation and include the following:. Effective palliation may be obtained in individual cases with various combinations of the following:.

The prevalence of Barrett metaplasia in adenocarcinoma of the esophagus suggests that Barrett esophagus is a premalignant condition.

Endoscopic surveillance of patients with Barrett metaplasia may detect adenocarcinoma at an earlier stage that is more amenable to curative resection. Strong consideration should be given to resection in patients with high-grade dysplasia in the setting of Barrett metaplasia.

The survival rate of patients with esophageal cancer is poor. Surgery is the treatment of choice for these small tumors. Once symptoms are present e. In some patients with partial esophageal obstruction, dysphagia may be relieved by placement of an expandable metallic stent [ 8 ] or by radiation therapy if the patient has disseminated disease or is not a candidate for surgery.

Alternative methods of relieving dysphagia have been reported, including laser therapy and electrocoagulation to destroy intraluminal tumor.

In the presence of complete esophageal obstruction without clinical evidence of systemic metastasis, surgical excision of the tumor with mobilization of the stomach to replace the esophagus has been the traditional means of relieving the dysphagia.

The optimal surgical approach for radical resection of esophageal cancer is not known. One approach advocates transhiatal esophagectomy with anastomosis of the stomach to the cervical esophagus.

A second approach advocates abdominal mobilization of the stomach and transthoracic excision of the esophagus with anastomosis of the stomach to the upper thoracic esophagus or the cervical esophagus. One study concluded that transhiatal esophagectomy was associated with lower morbidity than was transthoracic esophagectomy with extended en bloc lymphadenectomy; however, median overall disease-free and quality-adjusted survival did not differ significantly.

However, the ability to obtain negative surgical margins, the adequacy of lymph node dissection, and long-term outcomes have not been fully established with this approach. In the United States, the median age of patients who present with esophageal cancer is 67 years. Age alone does not determine therapy for patients with potentially resectable disease.

Phase III trials have compared preoperative concurrent chemoradiation therapy with surgery alone for patients with esophageal cancer. For early-stage tumors, the role of preoperative chemoradiation remains controversial. The effects of preoperative chemotherapy are being evaluated in randomized trials.

Several studies have demonstrated a survival benefit with preoperative chemotherapy compared with surgery alone. The interpretation of the results from the intergroup and preoperative chemotherapy trials is challenging because T or N staging was not reported, and prerandomization and radiation could be offered at the discretion of the treating oncologist.

For patients who are deemed either medically inoperable or have tumors that are unresectable, the efficacy of definitive chemoradiation has been established in numerous randomized controlled trials. Two randomized trials have shown no significant OS benefit for postoperative radiation therapy compared with surgery alone.

Information about ongoing clinical trials is available from the NCI website. Stage 0 squamous cell esophageal cancer is rarely seen in the United States, but surgery has been used. Standard treatment options for stage I esophageal cancer include the following:[ 1 - 5 ].

Standard treatment options for stage II esophageal cancer include the following:[ 1 ]. Standard treatment options for stage III esophageal cancer include the following:. Esophageal cancer responds to many anticancer agents. Palliation presents difficult problems for all patients with recurrent esophageal cancer. All patients should be considered candidates for clinical trials as outlined in the Treatment Option Overview for Esophageal Cancer section of this summary.

General Information About Esophageal Cancer

Правое запястье в гипсе. На вид за шестьдесят, может быть, около семидесяти. Белоснежные волосы аккуратно зачесаны набок, в центре лба темно-красный рубец, тянущийся к правому глазу. Ничего себе маленькая шишка, - подумал Беккер, вспомнив слова лейтенанта. Посмотрел на пальцы старика - никакого золотого кольца. Тогда он дотронулся до его руки.

 Ну видите, все не так страшно, правда? - Она села в кресло и скрестила ноги.  - И сколько вы заплатите. Вздох облегчения вырвался из груди Беккера. Он сразу же перешел к делу: - Я могу заплатить вам семьсот пятьдесят тысяч песет. Пять тысяч американских долларов.
