Q ) Hereditary diffuse Gastric carcinoma is associated with which  breast cancer
A. Ductal carcinoma NOS subtype
B. Lobular carcinoma
C. DCIS
D. Metaplastic carcinoma

Answer for Q 79

Majority of Gastric Cancers are sporadic,

1–3% of GCs arise as a result of inherited cancer predisposition syndromes.

 Li-Fraumeni syndrome, Lynch syndrome, Peutz-Jeghers syndrome, hereditary breast and ovarian cancer,MUTYH-associated adenomatous polyposis (MAP), familial adenomatous polyposis,  juvenile polyposis syndrome and PTENhamartoma tumour syndrome (Cowden syndrome).

Retained antrum syndrome

Retained antrum syndrome

Q) True about retained antrum syndrome after gastrectomy  are all except

a) It is a persistent hypergastrinemic state

b) It is only seen after Billroth II Gastrectomy

c) Technetium labelled food is not helpful in diagnosing this condition

d) Serum gastrin is usually less than 1000 pg/ml


Answer c

 After billroth II gastrectomy, if a cuff of gastric mucosa remains with duodenum, this entity is called as retained antrum syndrome. This cuff of gastric mucosa is cut off from the proximal stomach and inhibitory effect of hormones such as VIP (Vasoactive Intestinal Peptide)  leading to a persistent hypergastrinemic state. ALso this gastric mucosa is continuously bathed by the alkaline contents of duodenum , which further increases the acid formation.

Both Basal and maximal gastric acid outputs increase but it is not as high as seen in zollinger ellison syndrome. Typically less than 1000 pg/ml

This condition can present as recurrent and persistent ulcerations. Technetium scanning is the diagnostic modality of choice. Treatment is re do surgery and antral excision.

Technetium pertechnate imaging has a sensitivity of 73% and specificity of 100%

Dumping Syndrome

Dumping Syndrome

Q) Late dumping syndrome is due to 

a) Excessive release of insulin

b) Food bolus in jejunum

c) Release of serotonin

d) Local enteric reflexes


Answer

a, Excessive release of Insulin 

Dumping syndrome are most common after billroth II gastrectomy followed by BI and Truncal vagotomy and gastro jejunostomy.

Dumping can occur 30 mins after food, (early dumping) or 2 hours after eating (late dumping). Early dumping has GI symptoms such as nausea, vomiting, epigastric fullness, diarrhea and abdominal pain.

Early dumping occurs due to rapid emptying of chyme in jejunum. This hyperosmolar fluid draws water from extracellular compartment to the lumen of small intestine causing intestinal distension and autonomic changes.Serotonin, bradykinin-like substances, neurotensin, and enteroglucagon are involved in early dumping.

Late dumping syndrome  has more cardiovascular symptoms such as palpitations, light headedness, dizziness, tachycardia, diaphoresis, flushing and blurred vision.

It occurs due to delivery of carbohydrates into jejunum, their absorption causes hyperglycemia and insulin release. Excessive insulin release leads to development of symptoms.

Treatment 

  1. Diet - Avoid carbohydrates, frequent small meals of protein and fat and separate liquids from solids
  2. surgery Conversion to Roux en Y

Borrmann’s classification for ca stomach

Borrmann’s classification for ca stomach

Q) According to Borrmann's Classification of Ca stomach Type II is

a) Fungating

b) Polypoid

c) Ulcerative

d) Infiltrative

Answer free

Ans  a

Fungating

Borrmann’s classification is for advanced gastric tumors. 

It is useful to distinguish between advanced and early gastric tumors because in advanced tumors neo adjuvant therapy improves over all survival.

The gross appearance of advanced gastric carcinomas can be divided into

Type I for polypoid growth

Type II for fungating growth,

Type III for ulcerating growth,

Type IV for diffusely infiltrating growth which is also referred to as linitisplastica
