May also consider
Blood tests
-FBC - Fe def anemia
-U&E, LFT - renal, kidney involvement
Management
-surgical
Surgical
- if limited to mucosa/submucosa => endoscopic submucosal resection
- if 5-10cm from OG junction - subtotal gastrectomy
- if U5cm from OG junction - total gastrectomy
- if extending into esophagus - esophagogastrectomy
Pre/postop chemotherapy
Lymphadenectomy
What are the types of surgery possible
Cancer in lower stomach Roux en Y jejunal anastomosis -remove lower stomach -reattach jejunum to upper stomach -reattach duodenum to jejunum and BD
Gastrojejunal anastomosis
- remove lower stomach
- reattach jejunum to upper stomach only
Cancer in upper stomach
Esophagogastric anastomosis
-remove upper stomach
-reattach duodenum to lower esophagus
Cancer in whole stomach
Esophagojejunal anastomosis
-like Roux en Y but whole stomach removed

T1 - submucosa
T2 - muscularis propria
T3 - serosa
T4 - left stomach, nearby structures
