Key facts

Oesophageal cancer at a glance.

The essentials, in plain English — what it is, how it’s staged in the UK today, and how modern multimodal treatment is chosen.

  • What it is

    Adenocarcinoma (now the most common UK subtype) and squamous cell carcinoma (still common in some groups) of the oesophagus.

  • Main precursor

    Barrett’s oesophagus is the main precursor lesion for oesophageal adenocarcinoma.

  • Symptoms are late

    Symptomatic dysphagia is often a late-stage sign — earlier detection depends on Barrett’s surveillance.

  • How it is staged

    Staging combines OGD + EUS + PET-CT, with laparoscopy for junctional tumours.

  • Standard chemotherapy

    Neoadjuvant FLOT chemotherapy is standard for resectable adenocarcinoma.

  • Immunotherapy

    Adjuvant nivolumab is now offered after chemoradiotherapy in selected patients.

Why this guide matters

Modern multimodal care changes outcomes.

Careful staging, neoadjuvant chemotherapy, minimally-invasive surgery and adjuvant immunotherapy have transformed what is achievable in resectable disease.

  • Barrett’s is the main precursor

    Adenocarcinoma almost always arises through Barrett’s oesophagus — surveillance is how earlier cancers are found.

  • Staging drives everything

    OGD, EUS and PET-CT together decide whether treatment is curative or palliative — and which regimen is used.

  • FLOT + surgery is now standard

    Perioperative FLOT chemotherapy plus minimally-invasive oesophagectomy is the modern standard for resectable adenocarcinoma.

How the diagnosis is made

From first symptom to a clear plan.

The two-week-wait upper GI pathway UK teams follow, in order — so you know what to expect and why.

  1. 01

    Assessing

    Symptom + reflux history

    A careful history — dysphagia, reflux, weight loss and Barrett’s risk — decides how urgently to investigate.

  2. 02

    Assessing

    Urgent OGD + biopsy (2WW)

    Progressive dysphagia triggers a two-week-wait upper GI endoscopy with biopsy of any suspicious lesion.

  3. 03

    Assessing

    Endoscopic ultrasound (T-stage)

    EUS gives the most accurate assessment of tumour depth (T-stage) and regional lymph nodes.

  4. 04

    Confirming

    PET-CT (M-stage)

    Whole-body PET-CT looks for distant metastases and guides curative versus palliative intent.

  5. 05

    Confirming

    Staging laparoscopy for GOJ tumours

    Gastro-oesophageal junction tumours get a laparoscopy to detect peritoneal disease missed by imaging.

  6. 06

    Planning

    HER2 status (adenocarcinoma)

    Adenocarcinomas are tested for HER2 — a positive result opens targeted treatment options.

  7. 07

    Planning

    Upper GI MDT

    A specialist upper GI multi-disciplinary team combines all results into a personalised treatment plan.

Typical timeline: 4–8 weeks from first OGD to a treatment plan.

Symptoms

What oesophageal cancer actually shows up as.

Symptoms are often late. When any of these appear — especially in combination — they deserve urgent investigation.

  • Dysphagia (progressive)

    Difficulty swallowing solids that progresses to soft foods and then liquids is the classic warning sign.

  • Weight loss

    Unintentional weight loss alongside swallowing problems needs urgent investigation.

  • Regurgitation

    Undigested food or saliva coming back up — often occurring soon after meals.

  • Retrosternal pain

    New pain behind the breastbone, sometimes worse on swallowing, deserves prompt review.

  • Iron-deficiency anaemia

    Unexplained iron-deficiency anaemia is a recognised presenting feature — the tumour bleeds slowly.

  • Vomiting

    Persistent vomiting, especially of undigested food, points to obstruction of the oesophagus.

  • Hoarse voice

    A new hoarse voice can signal recurrent laryngeal nerve involvement by an advanced tumour.

  • Red flag

    Dysphagia to solids progressing to liquids with weight loss — two-week-wait referral for OGD.

Treatment

How oesophageal cancer is treated in the UK.

Treatment is chosen by stage, subtype and fitness — from endoscopic resection of very early tumours, through neoadjuvant chemotherapy and minimally-invasive surgery, to palliative care.

  • Endoscopic mucosal resection (early)

    For very early (T1a) tumours confined to the mucosa — resected endoscopically without open surgery.

  • Minimally-invasive oesophagectomy

    Laparoscopic and thoracoscopic removal of the oesophagus — the mainstay of curative surgery today.

  • Neoadjuvant FLOT chemotherapy

    Fluorouracil, leucovorin, oxaliplatin and docetaxel — standard before surgery for resectable adenocarcinoma.

  • Chemoradiotherapy (CROSS regimen)

    Carboplatin, paclitaxel and radiotherapy before surgery — used particularly for squamous cell disease.

  • Adjuvant nivolumab (after CRT)

    Immunotherapy given after chemoradiotherapy and surgery in selected patients to reduce recurrence.

  • Palliative stent

    A self-expanding metal stent placed at endoscopy restores swallowing in advanced disease.

  • Palliative chemo

    Systemic chemotherapy — sometimes with immunotherapy or HER2-targeted agents — for metastatic disease.

  • Best supportive care

    Symptom control, nutritional support and specialist palliative care when curative treatment is not appropriate.

Red flags

When oesophageal cancer becomes an emergency.

Any of these situations — during treatment or in advanced disease — needs same-day medical help. Do not wait.

  • Complete dysphagia + aspiration

    Inability to swallow saliva, with coughing or aspiration, needs same-day hospital assessment.

  • Massive haemorrhage

    Vomiting large volumes of blood or passing melaena is a life-threatening emergency — call 999.

  • Perforation post-EMR / stent

    Severe chest pain, fever or surgical emphysema after an endoscopic procedure — urgent A&E.

  • Anastomotic leak

    Fever, chest pain or breathlessness after oesophagectomy may signal a leak — return to the surgical team immediately.

  • Neutropenic sepsis

    Fever within 6 weeks of chemotherapy — attend A&E within an hour for antibiotics.

  • Malnutrition

    Rapid weight loss with poor oral intake needs urgent dietetic and nutritional support.

  • Recurrent laryngeal nerve palsy

    A new hoarse voice or weak cough after treatment needs ENT and swallowing assessment.

  • Trachea-oesophageal fistula

    Coughing after every swallow, especially with liquids, may signal an abnormal connection to the airway.

  • Palliative-stage crisis

    Uncontrolled pain, vomiting or bleeding in advanced disease — call your specialist palliative team today.

Living with it

A long-term journey, with structured support.

Four things that make the biggest difference day to day — follow-up, nutrition, side-effect control and specialist MDT support.

A quiet reminder

Ask for a dietitian early.

Nutritional support before, during and after treatment protects strength, reduces complications and speeds recovery.

  1. 01 Monitoring

    Follow-up after treatment

    Regular upper GI clinic review with symptom check, weight monitoring and imaging when indicated keeps recurrence detection on track.

  2. 02 Nutrition

    Eating after oesophagectomy

    Smaller, more frequent meals and specialist dietitian input help you rebuild weight and strength after surgery.

  3. 03 Side effects

    Reflux and dumping

    Reflux and dumping syndrome are common after surgery — both improve with dietary changes and targeted medication.

  4. 04 Reviews

    Structured MDT follow-up

    A named clinical nurse specialist and regular MDT reviews mean issues are picked up early and dealt with quickly.

Frequently asked

Everything we get asked about oesophageal cancer.

Quick answers on Barrett’s, staging, FLOT chemotherapy, oesophagectomy and when to worry.

  • What is oesophageal cancer?

    A cancer arising from the lining of the oesophagus. In the UK, adenocarcinoma (linked to reflux and Barrett’s oesophagus) is now the most common subtype, while squamous cell carcinoma remains common in some groups.

  • What is Barrett’s oesophagus and why does it matter?

    Barrett’s oesophagus is a change in the lining of the lower oesophagus caused by long-standing reflux. It is the main precursor lesion for oesophageal adenocarcinoma, which is why people with Barrett’s enter a surveillance programme.

  • How is oesophageal cancer staged?

    Staging combines OGD with biopsy, endoscopic ultrasound for local (T and N) stage, and PET-CT for distant spread. Gastro-oesophageal junction tumours also get a staging laparoscopy to check for peritoneal disease.

  • What is FLOT chemotherapy?

    FLOT is a combination of fluorouracil, leucovorin, oxaliplatin and docetaxel given before and after surgery. It is the standard neoadjuvant regimen for resectable oesophageal and gastro-oesophageal adenocarcinoma.

  • What is a minimally-invasive oesophagectomy?

    An operation to remove the oesophagus using laparoscopic and thoracoscopic (keyhole) techniques instead of large open incisions. It reduces recovery time and complications compared with traditional open surgery.

  • When should I worry about swallowing symptoms?

    Difficulty swallowing solids that progresses to liquids, especially with weight loss, needs urgent investigation — a two-week-wait referral for upper GI endoscopy. New hoarse voice, vomiting blood or unexplained iron-deficiency anaemia also warrant prompt review.
