Oesophageal Carcinoma
On this page
Direct answer
Dysphagia that progresses from solids to liquids over weeks, with weight loss, in a middle-aged Indian tobacco user is oesophageal carcinoma until endoscopy and biopsy prove otherwise. Squamous cell carcinoma dominates in India — driven by tobacco, areca nut, alcohol and scalding-hot beverages, with among the world's highest incidence rates reported from the Northeast, particularly Mizoram and Assam — and favours the mid-thoracic oesophagus, whereas adenocarcinoma arising in Barrett's metaplasia dominates Western series and favours the lower third. Staging uses contrast-enhanced CT chest-abdomen, PET-CT where available, and endoscopic ultrasound for early tumours. Localised disease is treated by oesophagectomy with gastric conduit reconstruction — Ivor Lewis for mid and lower tumours, three-stage McKeown for upper thoracic — while cervical tumours and unfit patients receive definitive chemoradiotherapy with cisplatin-based regimens.
What you must remember
- Histology-geography link: squamous carcinoma is the commonest type in India (mid-third predilection); adenocarcinoma, linked to gastro-oesophageal reflux and Barrett's change, is commoner in obese Western populations and rises wherever reflux disease rises.
- Risk factors worth quoting: tobacco (smoked and chewed), areca nut and gutkha, alcohol, opium usage reported in some Iranian and Indian cohorts, very hot beverages, achalasia, caustic strictures, Plummer-Vinson syndrome (iron deficiency with post-cricoid web, classically in middle-aged women).
- Indian anchor: the Northeast "oesophageal cancer belt" — registries from Mizoram, Assam and neighbouring states report rates among the highest globally, attributed to tobacco chewing, areca nut, smoked meat and hot tea consumption.
- Symptom sequence: dysphagia is progressive and late — a tumour must encircle much of the lumen before solids stick — so weight loss, retrosternal discomfort, regurgitation and hoarseness (recurrent laryngeal nerve involvement) are often established at presentation; supraclavicular nodes are examined in every patient.
- Staging: endoscopy with biopsy is the tissue step; CECT chest and abdomen for extent, endoscopic ultrasound for T and early nodal staging, PET-CT for occult metastases; bronchoscopy is added for tumours at or above the carina to exclude fistulisation.
- Surgical anatomy of choice: Ivor Lewis (laparotomy plus right thoracotomy with intrathoracic anastomosis) for mid and lower-third tumours; McKeown three-stage (right chest, abdomen, neck anastomosis) for upper thoracic; transhiatal oesophagectomy avoids thoracotomy with cervical anastomosis; the stomach is the preferred conduit, colon when the stomach is unsuitable.
- Non-surgical definitive treatment: cervical oesophageal cancers and medically unfit patients receive definitive chemoradiotherapy (cisplatin with 5-fluorouracil); salvage oesophagectomy is considered for persistent local disease.
- Palliation for advanced dysphagia: self-expanding metal stenting gives the quickest relief, with radiotherapy brackets, feeding gastrostomy or jejunostomy when stenting is unsuitable.
A worked dysphagia case
A 58-year-old man from Siliguri, a chronic bidi smoker and gutkha chewer, reports two months of dysphagia first to rice, now to dal, and 6 kg of weight loss; he points to retrosternal stuck-food discomfort. The reasoned pathway: urgent endoscopy with biopsy of the exophytic mid-oesophageal lesion (multiple biopsies, since squamous tumours ulcerate and necrose), then CECT chest-abdomen and, if resources allow, PET-CT, which shows a T3 tumour with peri-oesophageal nodes and no metastases. Because the tumour is mid-thoracic and he is fit, he receives neoadjuvant chemoradiotherapy or chemotherapy followed by Ivor Lewis oesophagectomy with a gastric tube reconstruction and feeding jejunostomy — the latter a routine part of Indian practice for post-operative nutrition. If PET had shown a solitary supraclavicular node or liver metastasis, the plan converts to systemic therapy with stenting for symptomatic relief, because surgery in metastatic disease adds morbidity without survival benefit. Hoarseness at presentation would prompt a vocal cord check before any surgery, since an immobile cord from recurrent laryngeal invasion changes both prognosis and the aspiration risk.
Where students slip
The recurring errors are site-histology mismatch and stage-surgery mismatch. Squamous cancer is mid-oesophageal and linked to tobacco and hot beverages; adenocarcinoma is lower-third and reflux-linked — a question pairing Barrett's oesophagus with mid-third squamous histology is internally inconsistent and the exam uses that. The second slip is offering oesophagectomy to everyone: cervical tumours get chemoradiotherapy, metastatic disease gets a stent, and poor-risk patients get definitive chemoradiotherapy or brachytherapy. Third, forgetting that the stomach — not colon — is the default reconstruction conduit because of its reliable blood supply, and that the anastomotic leak and recurrent laryngeal nerve palsy are the two complications the viva always reaches.
Frequently asked questions
Which histological type of oesophageal cancer is commonest in India?
Squamous cell carcinoma, concentrated in the mid-thoracic oesophagus, driven by tobacco, areca nut, alcohol and hot beverage consumption, with the highest rates reported from the Northeastern states.
Which operation is standard for a mid-thoracic oesophageal carcinoma?
Ivor Lewis oesophagectomy — laparotomy with gastric conduit formation plus right thoracotomy and intrathoracic anastomosis — in a fit patient after appropriate staging.
When is definitive chemoradiotherapy preferred over surgery?
For cervical oesophageal tumours (where resection sacrifices the larynx), for medically unfit patients, and as an alternative in locally advanced disease with poor response, typically cisplatin-based regimens.
How is malignant dysphagia palliated in advanced disease?
Self-expanding metal stent placement gives the most rapid swallowing relief, supplemented by feeding gastrostomy or jejunostomy and palliative radiotherapy or chemotherapy.
What is the Plummer-Vinson syndrome association?
Iron-deficiency anaemia with a post-cricoid web causing dysphagia, classically in middle-aged women, carrying a recognised risk of squamous carcinoma in the upper oesophagus.
