Oesophageal Cancer: Understanding the Disease, Symptoms, Diagnosis and Treatment
Oesophageal cancer develops when abnormal cells in the oesophagus, the muscular tube that carries food from the mouth to the stomach, begin to grow uncontrollably.
The oesophagus passes through the chest and connects to the stomach. Because it is responsible for transporting food and liquids, cancers developing in this organ can cause difficulty swallowing, one of the most important symptoms of oesophageal cancer.
Oesophageal cancer is not one single disease. The two major types are:
- Squamous cell carcinoma
- Adenocarcinoma
The type of cancer, its location, stage, molecular characteristics and the patient’s overall health all influence treatment.
Modern treatment may involve:
- GI Surgical Oncology
- Medical Oncology
- Radiation Oncology
- Endoscopy
- Chemotherapy
- Immunotherapy
- Targeted therapy in selected situations
- Radiation therapy
- Surgery
- Nutritional support
- Molecular diagnostics
- Supportive care
At Basavatarakam Indo-American Cancer Hospital & Research Institute (BIACH&RI), Hyderabad, appropriate patients can be evaluated through a multidisciplinary approach involving GI Surgical Oncology, Medical Oncology, Radiation Oncology, Gastroenterology, Radiology, Pathology, Nuclear Medicine, Molecular Diagnostics, Clinical Nutrition and supportive-care teams.
What Is the Oesophagus?
The oesophagus is a muscular tube approximately 25 centimetres long in adults.
It connects the throat to the stomach.
Its main function is to move swallowed food and liquids into the stomach through coordinated muscular contractions.
The oesophagus passes through:
- The neck
- The chest
- The diaphragm
It then joins the stomach.
Because of its location, oesophageal cancer treatment may require coordination between gastrointestinal surgeons, medical oncologists, radiation oncologists, gastroenterologists, radiologists and other specialists.
What Is Oesophageal Cancer?
Oesophageal cancer occurs when abnormal cells in the lining of the oesophagus begin to multiply uncontrollably.
The two main types are:
Squamous Cell Carcinoma
Squamous cell carcinoma develops from the flat cells lining the oesophagus.
It can occur in different portions of the oesophagus and is particularly associated with certain lifestyle and environmental risk factors.
Adenocarcinoma
Adenocarcinoma develops from glandular cells.
It commonly occurs in the lower portion of the oesophagus, often near the junction with the stomach.
The treatment approach depends on the exact tumor characteristics.
Where Does Oesophageal Cancer Develop?
The oesophagus is commonly divided into:
- Cervical oesophagus
- Upper thoracic oesophagus
- Middle thoracic oesophagus
- Lower thoracic oesophagus
- Oesophagogastric junction region
Tumor location can influence:
- Surgical approach
- Radiation planning
- Reconstruction
- Treatment sequence
What Causes Oesophageal Cancer?
There is no single cause of oesophageal cancer.
Several factors can increase risk.
These include:
- Tobacco use
- Heavy alcohol consumption
- Long-standing gastroesophageal reflux disease
- Barrett’s oesophagus
- Obesity
- Certain dietary factors
- Previous caustic injury to the oesophagus
- Certain inherited conditions
- Increasing age
The risk factors can differ between squamous cell carcinoma and adenocarcinoma.
Tobacco and Oesophageal Cancer
Tobacco use significantly increases the risk of oesophageal cancer.
Smoking exposes the oesophageal lining to carcinogenic substances.
Smokeless tobacco products may also increase cancer risk.
Avoiding tobacco is one of the most important measures for reducing the risk of several cancers, including oesophageal cancer.
Alcohol and Oesophageal Cancer
Heavy alcohol consumption is an important risk factor, particularly for oesophageal squamous cell carcinoma.
The combination of tobacco and heavy alcohol exposure can further increase risk.
Reducing or avoiding alcohol can help lower cancer risk and improve overall health.
Acid Reflux and Oesophageal Cancer
Long-standing gastroesophageal reflux disease, or GERD, can repeatedly expose the lower oesophagus to stomach acid.
Over time, chronic reflux can cause changes in the oesophageal lining.
One such condition is Barrett’s oesophagus.
Barrett’s oesophagus can increase the risk of oesophageal adenocarcinoma.
What Is Barrett’s Oesophagus?
Barrett’s oesophagus occurs when the normal lining of the lower oesophagus changes because of long-term acid exposure.
It is considered a precancerous condition because it is associated with an increased risk of oesophageal adenocarcinoma.
Not everyone with Barrett’s oesophagus develops cancer.
People diagnosed with Barrett’s oesophagus may require appropriate surveillance depending on the presence and degree of dysplasia and their individual risk.
Symptoms of Oesophageal Cancer
Difficulty swallowing is one of the most important symptoms of oesophageal cancer.
Other symptoms may include:
- Difficulty swallowing solid food
- Difficulty swallowing liquids as the disease progresses
- Feeling that food is stuck in the chest
- Painful swallowing
- Unexplained weight loss
- Persistent heartburn
- Chest discomfort
- Persistent indigestion
- Regurgitation of food
- Persistent cough
- Hoarseness
- Vomiting
- Fatigue
- Anaemia
- Gastrointestinal bleeding in some patients
These symptoms can also occur in non-cancerous conditions.
However, progressive swallowing difficulty should always be medically evaluated.
Difficulty Swallowing: An Important Warning Sign
Difficulty swallowing is called dysphagia.
It may initially occur only when eating solid foods.
As an obstruction becomes more significant, difficulty may progress to softer foods and eventually liquids.
This progression should never be ignored.
Persistent or worsening dysphagia requires prompt evaluation.
Unexplained Weight Loss
People with oesophageal cancer may lose weight because:
- Swallowing becomes difficult
- Eating becomes uncomfortable
- Food intake decreases
- The tumor affects nutrition
- Cancer-related metabolic changes occur
Unintentional weight loss associated with swallowing difficulty deserves medical attention.
Chest Pain or Discomfort
Some people with oesophageal cancer may experience pain or pressure behind the breastbone.
This can sometimes be mistaken for:
- Acidity
- Heartburn
- Indigestion
- Musculoskeletal pain
Persistent or unexplained chest or upper abdominal discomfort should be evaluated appropriately.
Hoarseness and Cough
Advanced oesophageal tumors can sometimes affect nearby structures.
This may result in:
- Persistent cough
- Voice changes
- Hoarseness
These symptoms have many possible causes, but persistent unexplained symptoms should be assessed.
When Should You See a Doctor?
Medical evaluation is especially important for:
- Progressive difficulty swallowing
- Difficulty swallowing solid food
- Difficulty swallowing liquids
- Unexplained weight loss
- Persistent heartburn
- Recurrent food regurgitation
- Persistent chest discomfort
- Unexplained anaemia
- Vomiting blood
- Black stools
- Persistent cough or hoarseness
Early evaluation can help identify the cause and, when cancer is present, determine the disease at an earlier stage.
How Is Oesophageal Cancer Diagnosed?
Diagnosis may involve:
- Medical history
- Physical examination
- Upper gastrointestinal endoscopy
- Biopsy
- Histopathology
- CT scan
- PET-CT in selected patients
- Endoscopic ultrasound
- Molecular and biomarker testing
- Additional investigations for staging
Upper GI Endoscopy for Oesophageal Cancer
Upper gastrointestinal endoscopy is one of the most important tests for suspected oesophageal cancer.
A flexible camera is passed through the mouth to examine:
- Oesophagus
- Stomach
- Upper small intestine
If an abnormal area is identified, the doctor can take a biopsy.
Biopsy and Histopathology
A biopsy provides tissue for microscopic examination.
Pathologists determine:
- Whether cancer is present
- Cancer type
- Tumor characteristics
- Relevant pathological features
The biopsy result is essential for deciding the appropriate treatment strategy.
CT Scan for Oesophageal Cancer
Contrast-enhanced CT of the chest and abdomen can help determine:
- Tumor location
- Tumor extent
- Nearby lymph nodes
- Lung involvement
- Liver involvement
- Other evidence of distant disease
CT is an important component of staging.
PET-CT for Oesophageal Cancer
PET-CT may be used in selected patients to evaluate for metabolically active disease.
It can help identify:
- Primary tumor activity
- Lymph-node involvement
- Distant metastases
PET-CT can be particularly useful when treatment with curative intent is being considered.
The decision to perform PET-CT depends on the patient’s clinical situation.
Endoscopic Ultrasound
Endoscopic ultrasound can help determine how deeply the tumor has invaded the oesophageal wall.
It may also help evaluate nearby lymph nodes.
In selected circumstances, EUS can assist with tissue sampling.
Staging of Oesophageal Cancer
Staging determines how far the cancer has developed.
Doctors evaluate:
- Depth of tumor invasion
- Regional lymph nodes
- Distant spread
Oesophageal cancer is generally categorized from:
- Stage I
- Stage II
- Stage III
- Stage IV
However, treatment planning requires more detailed assessment than stage alone.
Tumor location, histological type, resectability, lymph-node involvement and overall patient fitness all matter.
Why Tumor Location Matters
Oesophageal tumors occur in different parts of the oesophagus.
Their location can influence:
- Surgical technique
- Extent of surgery
- Radiation fields
- Reconstruction
- Treatment sequence
Therefore, the treatment plan must be individualized.
Resectable Oesophageal Cancer
Some oesophageal cancers can potentially be removed surgically.
For selected patients, treatment may involve:
Chemotherapy and/or radiation therapy → surgery
The exact sequence depends on tumor type, stage, location and current treatment protocols.
Locally Advanced Oesophageal Cancer
Locally advanced cancer may involve deeper layers of the oesophageal wall and/or nearby lymph nodes.
Treatment may involve combined approaches such as:
- Chemotherapy
- Chemoradiation
- Surgery
- Immunotherapy in selected settings
Multidisciplinary planning is particularly important for these patients.
Advanced Oesophageal Cancer
When oesophageal cancer has spread to distant organs, treatment generally focuses on controlling the disease, relieving symptoms and maintaining quality of life.
Depending on tumor characteristics, treatment may include:
- Chemotherapy
- Immunotherapy
- Targeted therapy for selected biomarker-defined cancers
- Radiation therapy
- Endoscopic procedures
- Nutritional support
- Supportive care
Treatment of Oesophageal Cancer
Treatment depends on:
- Cancer type
- Stage
- Tumor location
- Tumor size
- Lymph-node involvement
- Resectability
- Biomarkers
- Overall health
- Nutritional condition
Treatment may include:
- Endoscopic treatment
- Surgery
- Chemotherapy
- Radiation therapy
- Chemoradiation
- Immunotherapy
- Targeted therapy
- Supportive care
Endoscopic Treatment for Early Oesophageal Cancer
Some very early oesophageal cancers may be suitable for endoscopic treatment.
Procedures can include:
- Endoscopic mucosal resection
- Endoscopic submucosal dissection
Suitability depends on:
- Depth of invasion
- Tumor size
- Tumor location
- Histology
- Risk of lymph-node involvement
These procedures are appropriate only for carefully selected early lesions.
Surgery for Oesophageal Cancer
Surgery to remove the oesophagus is called an oesophagectomy.
It is a major cancer operation.
Depending on the tumor location and surgical plan, the operation may involve removal of:
- Part or most of the oesophagus
- Part of the stomach
- Nearby lymph nodes
The stomach or another part of the digestive tract may then be used to reconstruct the food pathway.
What Is Oesophagectomy?
Oesophagectomy involves removing the cancer-bearing portion of the oesophagus and reconstructing the digestive tract.
Different surgical approaches may be used.
The choice depends on:
- Tumor location
- Tumor stage
- Patient anatomy
- Previous treatment
- Surgeon expertise
Types of Oesophagectomy
Approaches may include:
- Transhiatal oesophagectomy
- Transthoracic oesophagectomy
- Minimally invasive oesophagectomy
- Hybrid surgical approaches
The most appropriate technique is determined on an individual basis.
Minimally Invasive and Robotic Oesophageal Surgery
Selected patients may be candidates for minimally invasive or robotic-assisted approaches.
Potential benefits can include:
- Smaller incisions
- Reduced surgical trauma
- Earlier mobilization
- Potentially shorter recovery in suitable patients
However, not every patient or tumor is appropriate for minimally invasive surgery.
The priority is complete and safe cancer treatment.
Lymph-Node Dissection
Oesophageal cancer can spread to nearby lymph nodes.
Therefore, lymph-node removal and pathological examination are important components of many oesophageal cancer surgeries.
The number and location of affected lymph nodes help determine the final stage and guide further treatment.
Chemotherapy for Oesophageal Cancer
Chemotherapy may be used:
- Before surgery
- With radiation therapy
- After surgery in selected cases
- For advanced disease
The treatment approach depends on the tumor type and stage.
Chemoradiation
Chemoradiation combines chemotherapy and radiation therapy.
For selected oesophageal cancers, chemoradiation can be used:
- Before surgery
- As definitive treatment when surgery is not appropriate
- For selected locally advanced cancers
The treatment plan depends on tumor location, histology, stage and patient fitness.
Radiation Therapy for Oesophageal Cancer
Radiation Oncology plays an important role in selected oesophageal cancer cases.
Radiation may be used:
- Before surgery
- With chemotherapy
- As definitive treatment in selected patients
- For symptom relief
- For selected metastatic sites
Modern radiation planning aims to deliver the required dose to the tumor while protecting nearby organs such as the heart and lungs.
Immunotherapy for Oesophageal Cancer
Immunotherapy has become an important part of treatment for selected oesophageal cancers.
It may be considered depending on:
- Tumor type
- Stage
- Biomarkers
- Previous treatment
- Overall health
Immunotherapy works by helping the immune system recognize and attack cancer cells.
Biomarker Testing
Modern oesophageal cancer treatment increasingly incorporates biomarker information.
Depending on the tumor type and clinical setting, testing may include:
- PD-L1
- HER2
- MSI/MMR
- Other relevant biomarkers
These results can influence treatment decisions, particularly in advanced disease.
HER2 in Oesophageal and Gastroesophageal Junction Cancer
HER2 testing may be relevant particularly in selected adenocarcinomas involving the gastroesophageal junction.
If a tumor is HER2-positive, HER2-directed treatment may be considered in appropriate clinical circumstances.
PD-L1 Testing
PD-L1 expression may help guide immunotherapy decisions in selected oesophageal cancers.
The significance of PD-L1 depends on:
- Histological type
- Disease stage
- Testing methodology
- Treatment setting
Doctors interpret the result together with other clinical information.
MSI/MMR Testing
MSI/MMR testing can identify tumors with mismatch-repair abnormalities.
A subset of gastrointestinal cancers with these characteristics may respond particularly well to immunotherapy.
Testing may therefore be important in selected patients.
Precision Oncology in Oesophageal Cancer
Precision oncology aims to match treatment to the biological characteristics of an individual tumor.
Molecular and biomarker testing can help identify:
- Potentially actionable alterations
- Immunotherapy biomarkers
- Targeted treatment opportunities
Not every patient requires the same molecular testing.
Testing should be selected according to the cancer type, stage and treatment context.
Treatment of Gastroesophageal Junction Cancer
Some cancers arise where the oesophagus meets the stomach.
These are called gastroesophageal junction (GEJ) cancers.
Their treatment requires careful assessment of:
- Exact tumor location
- Histology
- Stage
- HER2 status
- PD-L1 status
- MSI/MMR status
- Resectability
Because these tumors overlap the oesophagus and stomach, multidisciplinary GI oncology planning is particularly important.
Managing Difficulty Swallowing
Difficulty swallowing can become a major problem in oesophageal cancer.
Depending on the patient’s treatment plan, options may include:
- Radiation therapy
- Systemic treatment
- Endoscopic procedures
- Oesophageal stenting in selected situations
- Nutritional support
The best option depends on whether the patient is receiving curative or palliative treatment and on the location of the obstruction.
Oesophageal Stents
An oesophageal stent can help keep a narrowed oesophageal passage open.
Stenting may be considered in selected patients with significant obstruction, particularly when immediate restoration of swallowing is required.
The decision is individualized.
Nutrition in Oesophageal Cancer
Nutrition is extremely important because difficulty swallowing can lead to:
- Weight loss
- Dehydration
- Malnutrition
- Muscle loss
- Reduced treatment tolerance
Nutrition assessment should ideally begin early.
Depending on the situation, nutritional support may involve:
- Modified diets
- Oral nutritional supplements
- Feeding tubes
- Other individualized nutritional strategies
Feeding Tubes
Some patients may require temporary nutritional support through a feeding tube.
The appropriate method depends on:
- Tumor location
- Planned treatment
- Surgical plan
- Nutritional status
The aim is to maintain adequate nutrition while cancer treatment continues.
Recovery After Oesophagectomy
Recovery after oesophagectomy can take time.
Patients may experience changes in:
- Eating patterns
- Appetite
- Digestion
- Weight
- Bowel habits
A multidisciplinary rehabilitation and nutrition program can help patients adapt.
Small, frequent meals may be recommended.
Long-Term Follow-Up
After treatment, follow-up may include:
- Clinical assessment
- Imaging when appropriate
- Endoscopy in selected patients
- Nutritional monitoring
- Weight monitoring
- Management of treatment-related effects
The follow-up plan is individualized according to the patient’s cancer and treatment.
Can Oesophageal Cancer Be Prevented?
Not all oesophageal cancers can be prevented.
However, certain risk factors can be reduced.
Important measures include:
- Avoid tobacco
- Avoid heavy alcohol consumption
- Maintain a healthy weight
- Manage chronic acid reflux
- Seek medical care for persistent reflux
- Follow surveillance recommendations for Barrett’s oesophagus when diagnosed
- Maintain a healthy diet
