Stomach Cancer

Stomach cancer is a tumour that develops from the inner lining of the stomach and is mostly of the adenocarcinoma type. H. pylori infection, chronic gastritis, atrophic gastritis and dietary habits are the main risk factors.

Overview

At the centre of treatment are surgical resection (subtotal or total gastrectomy) and extensive lymph node dissection. In locally advanced cases, perioperative chemotherapy markedly increases survival.

Who Is It For?

  • Those with complaints of unexplained dyspepsia, early satiety, nausea and weight loss
  • Those in whom a suspicious lesion or a positive biopsy is detected at endoscopy
  • Those who are H. pylori positive and show an increased risk during follow-up for chronic gastritis
  • Those with a family history and carriers of a genetic syndrome (CDH1)
  • Patients with iron deficiency anaemia who require upper GI screening

Treatment Process

  1. 1

    Pre-Assessment & Diagnosis

    The diagnosis is confirmed and the stage of the disease clarified through a detailed history, physical examination and the necessary imaging and laboratory tests.

  2. 2

    Planning & Preparation

    An anaesthesia consultation, bleeding profile and review of any accompanying conditions are carried out; a multidisciplinary council decision is taken when needed.

  3. 3

    Procedure / Operation

    The procedure is performed with the technique most suitable for the patient (laparoscopic, robotic or open); tissue integrity and oncological principles are preserved.

  4. 4

    Follow-up & Monitoring

    Early mobilization, pain control and wound monitoring are provided; suture removal and a general assessment check-up are planned after discharge.

Recovery & Aftercare

After a total gastrectomy, eating is gradually relearned; small portions and frequent meals are essential.

Hospital Stay

5–10 days

Recovery Time

4–6 weeks

Follow-up

Every 3 months for the first 2 years

Frequently Asked Questions

Can I eat normally after the stomach is removed?

Yes. Small, frequent meals are recommended at first; over time the portion size and variety are increased. Lifelong B12 supplementation is required after a total gastrectomy.

A polyp was seen at endoscopy, is it cancer?

A polyp is not cancer; however, some types of polyps carry a risk. The decision to follow up or remove it is made according to the pathology result and size.

Is robotic gastrectomy as effective as open surgery?

In experienced hands, robotic gastrectomy shows results equivalent to open surgery in terms of lymph node clearance and oncological margins.

Is perioperative chemotherapy essential?

In locally advanced cases (T2 and above, lymph node positive), perioperative chemotherapy markedly increases survival and is recommended in guidelines.
