Q

Describe oesophageal tumors

A

Oesophageal tumours are mostly carcinomas but can be adenocarinoma if develop from Barrett’s

Typically present with progressive dysphagia but if presenting with symptoms, likely has metastasised

Risk factors include smoking and Barrett’s

Q

Describe gastric cancers

A

Are adenocarcinomas and typically occurs in antrum or cardia

If gastric cancer occurs near oesophageus can have dysphagia

If gastric cancer occurs near duodenum can have vomiting

Present with pain similar to peptic ulcer and 50% have palpable mass

Risk factors: high salt diet, smoking, family history, H. pylori

Q

Name some cancers other than gastric and oesophageal that can occur in the GI system (not intestines)

A

Liver malignancies - hepatocellular carcinomas can occur though are rare

Bile duct cancer - cholangiocarcioma. PSC increases risk

Pancreatic cancer - 80% are ductal adenocarcinomas. Poor prognosis as usually advanced on diagnosis. Have jaundice if malignancy occurs in the head while if it occurs in the body/tail have more vague symptoms. Can affect endocrine/exocrine function. Risk factors: family history, smoking, age, male, chronic pancreatitis

Q

What are some benign causes of a change in bowel habits

A

Hypercalcaemia

Thyroid disorders

IBD

IBS

Medication

Coeliac disease

17
Q

What are the risk factors for large bowel cancer

A

Family history

IBD - chronic inflammation

Polyposis syndromes - FAP, HNPCC

Diet and lifestyle

18
Q

Compare right sided colon cancer to left sided colon cancer

A

Right sided is less likely to cause bowel obstruction (looser stools and larger lumen). Have weight loss, anaemia, mass in right iliac fossa. Change in bowel habits will be late. More advanced disease at presentation. Tumour is fungating - grows outwards

Left sided is more likely to cause bowel obstruction (harder stools and smaller lumen). Have weight loss, rectal bleeding, tenesmus, mass in left iliac fossa. Have early change in bowel habit. Less advanced at presentation usually. Tumour is stenosing - grows in ring like fashion

19
Q

What are the types of small bowel cancer and what are the risk factors

A

Types - stromal, lymphomal, adenocarcinoma, sarcoma, carcinoid/neuroendocrine tumours

Risk factors: IBD, coeliac disease, FAP, diet

20
Q

What does the management of GI malignancies consist of

A

TNM staging

Blood test - FBC, tumour markers (e.g. CEA, CA 19-9)

CT/MRI

Endoscopy/colonoscopy

Capsule endoscopy

Biopsy

Treatment: chemotherapy, radiotherapy, surgical resections
