Esophageal Cancer
Esophageal cancer often shows itself first as difficulty swallowing — a symptom that should never be put down to age. Caught early, it is treatable; even when locally advanced, the combination of chemotherapy, radiation and surgery offers a real chance of cure.
What esophageal cancer is — in plain words
The esophagus is the muscular tube that carries food from the mouth to the stomach. Cancer of the esophagus comes in two main forms:
- Squamous cell carcinoma — more common in our region, linked to smoking, alcohol, hot beverages, and certain dietary patterns. Usually arises in the upper and middle esophagus.
- Adenocarcinoma — increasingly common worldwide, linked to chronic acid reflux, Barrett's esophagus, and obesity. Usually arises in the lower esophagus, close to the stomach.
Signs and symptoms to take seriously
Difficulty swallowing
First with solids (meat, bread), later with softer foods and liquids. Any new, progressive trouble swallowing needs prompt endoscopy.
Pain on swallowing
A sticking or burning sensation behind the breastbone when food goes down.
Weight loss
Unintended weight loss, often because eating has become uncomfortable.
Chronic reflux symptoms
Long-standing heartburn — especially if it has changed character or no longer responds to usual treatment.
"Trouble swallowing is one symptom I never let slide. It almost always has a cause, and the cause is usually treatable — but only if we find it."
How esophageal cancer is diagnosed
- Upper GI endoscopy — direct visualisation of the tumour with biopsies for diagnosis.
- Endoscopic ultrasound (EUS) — to measure how deeply the tumour invades the esophageal wall and to assess nearby lymph nodes.
- CT scan of chest, abdomen and pelvis — for staging.
- PET-CT — particularly useful in esophageal cancer to detect distant spread and to plan radiation fields.
- HER2, PD-L1, MSI testing — on the biopsy, especially for adenocarcinomas.
- Nutritional assessment — many patients are already losing weight at diagnosis; this is part of the work-up, not an afterthought.
Stages — what the numbers mean
Stage I
Cancer in the inner layers of the wall, no nodes. Endoscopic removal may be enough for very superficial disease; surgery for others.
Stage II–III
Deeper invasion or local lymph node involvement. Trimodal therapy — chemoradiation followed by surgery — is the standard for fit patients.
Stage IVA
More extensive local or regional disease. Treated with chemoradiation, sometimes followed by surgery in selected cases.
Stage IVB (metastatic)
Spread to distant organs. Treated with systemic therapy — chemotherapy with immunotherapy and, for HER2-positive tumours, targeted therapy.
How we treat esophageal cancer
Trimodal therapy (chemoradiation followed by surgery)
For resectable stage II and III disease, the standard plan is about 5 weeks of combined chemotherapy and radiation, followed 6–8 weeks later by an esophagectomy. This approach was established by the CROSS trial and produces better outcomes than surgery alone. Patients who have a complete response on imaging after chemoradiation may, in some cases, be offered "watch and wait" instead of immediate surgery — a discussion worth having.
Definitive chemoradiation (without surgery)
For squamous cell carcinoma especially, chemoradiation alone — without surgery — can be curative. This is particularly appropriate for upper esophageal tumours, for patients unfit for major surgery, or as a chosen alternative.
Surgery
Esophagectomy is a major operation, removing the affected portion of the esophagus and rebuilding the swallowing route, usually with the stomach pulled up into the chest. Recovery is significant and requires a dedicated surgical team and good post-operative care.
Adjuvant immunotherapy
Nivolumab after chemoradiation and surgery, given for up to a year, improves outcomes in patients with residual disease in the surgical specimen. This is now standard.
Chemotherapy
Common regimens combine a platinum (carboplatin, cisplatin or oxaliplatin) with a taxane or fluoropyrimidine. FLOT is used for adenocarcinomas treated as gastro-esophageal junction tumours. Read more about chemotherapy →
Targeted therapy and immunotherapy in advanced disease
For HER2-positive adenocarcinoma, trastuzumab is added to chemotherapy. Checkpoint inhibitors (pembrolizumab, nivolumab) combined with chemotherapy have become first-line standard for many advanced esophageal cancers, with the benefit largest in PD-L1 high tumours. Read more about immunotherapy →
Nutritional support and stenting
If swallowing is severely compromised, options include an esophageal stent (to keep the passage open), a feeding tube placed through the stomach (PEG) or jejunum, and intensive dietetic support. These are not signs of giving up — they keep the patient strong enough to tolerate active treatment.
What the outlook honestly looks like
For stage I esophageal cancer, five-year survival can exceed 70%. For locally advanced disease (stage II–III) treated with full trimodal therapy, five-year survival is in the 40–50% range, with newer immunotherapy data continuing to push this higher. For metastatic disease, median survival on modern chemo-immunotherapy is approaching 18 months and rising.
Prevention and surveillance
- Stop smoking, moderate alcohol. Both are clear risk factors, particularly for squamous cell carcinoma.
- Treat chronic reflux properly. Long-standing acid reflux raises the risk of Barrett's esophagus and adenocarcinoma.
- Endoscopic surveillance of Barrett's esophagus — to catch dysplasia or early cancer at a curable stage.
- Maintain a healthy weight — obesity is a clear risk factor for adenocarcinoma.
Life during treatment
The chemoradiation phase is intensive; patients often need active nutritional support and management of swallowing pain. After esophagectomy, eating changes — smaller, more frequent meals, sitting upright after eating, attention to reflux. Most patients return to a reasonable diet over months, but some adaptations are permanent.
After treatment — survivorship
Surveillance with clinic visits, endoscopy and CT scans continues for years. Long-term nutritional follow-up, attention to bone health (especially after gastric pull-up), and management of reflux all matter. Read about survivorship care →
