Fibrolamellar HCC

by
Fibrolamellar HCC MCQ – Liver Tumors – NEET SS Surgery
Q) Fibrolamellar HCC is associated with? ( #NEET Onco Questions 2020)
✅ Correct Answer: a) Young age

🔍 Explanation:
- Fibrolamellar Hepatocellular Carcinoma typically affects younger patients without underlying cirrhosis.
- It is often well-demarcated, encapsulated, and contains a central fibrotic scar.
- Prognosis is better than classic HCC due to higher resectability, absence of chronic liver disease, and a more indolent behavior.
- Long-term survival can be expected in ~50–75% of patients.
- However, lymph node metastasis **can occur**, and when present, is associated with poorer outcomes.

Crohn Disease Pathology

by

Q) Which of the following is not characteristic of Crohn Disease  : * (From AIIMS 2020 November GI)  

a) Granular mucosa
b) Transmural involvement
c) Skip lesions
d) Giant cell granuloma

Ans a ) Granular Mucosa- This is a feature of ulcerative colitis ( Table 49-7 Sabiston 20) 

The typical gross appearance of ulcerative colitis is hyperemic mucosa.

Friable and granular mucosa is common in more severe cases, and ulceration may not be readily evident. ( Saby 1340) 

IN Crohn disease - Microscopically, there are focal areas of chronic inflammation involving all layers of the intestinal wall with lymphoid
aggregates. Non-caseating giant cell granulomas are found in 60% of patients and when present clearly allow a confident diagnosis of CD.

Gastrinoma diagnosis

by

Q) Gastrinoma false is (AIIMS GI 2020) 
a) Fasting serum gastrin levels are  1000 g/ml
b) Duodenotomy should be done in all cases
c) Diarrhea most common symptom
d) SRS can localize 80% cases

Ans  )  c -

Duodenotomy detects 25% to 30% of tumors not seen on preoperative imaging.

Gastrin  levels higher than 1000 pg/mL are strongly suggestive of gastrinoma, provided that the patient demonstrated increased gastric acid  secretion ( gastric secretion ph should be less than 2) 

Most common is abdominal pain ( 75%) In 10% to 20% of patients, diarrhea is the only symptom

 Saby page 954) 

SRS should be performed because almost all gastrinomas express somatostatin receptors.

Meld score uses and drawbacks

by

Q. All are true about Na-MELD except :

a) It corelates with cirrhosis
b)Range of sodium value  is 125-137
c)It relates to vasoconstriction
d) Used for allocation in DDLT patients

Ans c

 MELD was originally developed to predict three-month mortality following transjugular intrahepatic portosystemic shunt (TIPS) placement and was derived using data from a population of 231 patients with cirrhosis who underwent elective TIPS placement.

Range of MELD score is 6-40

MELD Score = 10 x (0.957 x Ln(serum creatinine mg/dL) + 0.378 x Ln(serum bilirubin  mg/dL) + 1.120 x Ln(INR) + 0.643 )

For candidates with an initial MELD score greater than 11, the MELD score is then re-calculated as follows:
MELDNa = MELD(i) + 1.32*(137-Na) - [0.033*MELD(i)*(137-Na)]

  • Sodium values less than 125 mmol/L will be set to 125, and values greater than 137 mmol/L will be set to 137.

It is used for allocation in DDLT to assess wait list mortality

MELD score has also proved to be an effective predictor of outcome in other situations, such as

  1. Patients with cirrhosis going for surgery and patients with fulminant hepatic failure or alcoholic hepatitis.
  2. The MELD score does have limitations in situations where the INR or creatinine may be elevated due to reasons other than liver disease, and its implementation for organ allocation purposes does not take into consideration several conditions that benefit from liver transplantation.

Smoking treatment

by

Q) Smoking cessation- Not a  first line drug option ?

a) Clonidine 

b) Nicotine replacement (patches)

c) Varenicline

d)  Bupropion

Ans A) clonidine

NRT ,  varenicline (Chantix), and bupropion (Zyban) are the three principal firstline pharmacotherapies recommended for use either alone or in combination 

Clonidine and nortriptyline—as second-line pharmacotherapies for tobacco dependence typically used when a smoker cannot use first-line medications due to either contraindications or lack of effectiveness.

Fong Score

by

Q. 56 year ls male is diagnosed with ca rectum and multiple liver metastasis . Which of the following is not a Poor risk factor according to Fong score

a) Node +
 b) Disease free interval more than 1 yr
c) 2 Liver Mets

d) Single metastasis 6 cm

Ans b 

Fong score is for Survival after treatment for metastatic colorectal cancer to the liver. It includes 5 variables for which score is alloted to each point

Nodal status of primary

Disease-free interval from the primary to discovery of the liver metastases of <12 months

Number of tumors >1,

Preoperative CEA level >200 ng/ml, and

Size of the largest tumor >5 cm

 

Steroid Refractory Ulcerative colitis

by

Q) Not used in steroid refractory severe Ulcerative Colitis ( AIIMS 2020 Nov) 

a) Infliximab
b) Azathioprine
c) Cyclosporine
d) Surgery

Ans b- Azathioprine

Cyclosporine is  immunomodulator indicated for second-line therapy in the case of severe, steroid refractory ulcerative colitis. Treatment is usually initiated after 3 to 5 days of failed steroid response

Tacrolimus is appropriate as second-line therapy in patients with severely active ulcerative colitis unresponsive to steroids.

The use of various anti–tumor necrosis factor-α  (TNF-α) monoclonal antibodies ( infliximab)  is well supported in the case of
severe ulcerative colitis refractory to steroids. 

Indication Surgery crohn disease

by

Q. Most common indication of surgery in Crohn's disease (#AIIMS GI )    (# Jejunum MCQS) 
a) Fistula
b) intractability
c) abscess
d) obstruction

Ans d Obstruction

Confusion between failure of medical therapy or obstruction as the ans. I have checked Bailey sabiston and Shackelford

2 books mention obstruction on top whereas one mentions failure of medical therapy. However with the improvement of medical management in the past decade, obstruction can be the ans

Crohn’s disease will require surgery at some time durin the course of their illness. Approximately 70% of patients will
require surgical resection within 15 years after diagnosis.

Indications for surgery include failure of medical treatment, bowel obstruction, and fistula or abscess formation. Most patients can
be treated with elective surgery,

CDH 1 gene

by

Q) CDH 1 gene is associated with which cancer

a) Breast

b) Colon

c) Prostate

d) Renal

ANs a

CDH 1 is with gastric and lobular breast cancer

The CDH1 gene is responsible for  making a protein called epithelial cadherin or E-cadherin.

Germline mutation in the CDH1 gene encoding E-cadherin is  shown to be associated with hereditary diffuse gastric cancer. Also RHOA gene is also associated with Ca stomach

Prophylactic total gastrectomy should be considered in patients with these mutations

Renal cancer is mainly associated with VHL gene

Gene mutation associated with CDH 

E Cadherin is involved in

a) Cell Adhesion

b) Cell maturation

c) Managing intracellular chemical signals

d) It acts as a tumor suppressor protein

Colon Lymphoma

by

Q) True about lymphoma of the colon?

a) More common in females

b) Most common in 3rd and 4th decade

c) Most common site is caecum

d) T cells are most commonly involved

Surgery Questions on Colon

MCQs in Rectum

Ans c

Lymphoma is uncommon in the colon/rectum occurring in 0.4% of patients; intestinal lymphoma and can present anywhere between the
second and eighth decades of life.

Most of these lesions are intermediate to high-grade B-cell lymphomas.

Affected men outnumber women about 1.5:1 

The majority of colorectal lymphomas are found in the cecum or ascending colon. More than 70% of colorectal lymphomas are proximal to the hepatic flexure. 

Colon Lymphoma Pathology Outlines 

Extranodal Marginal Zone B-Cell Lymphoma

ENMZL, formerly known as marginal zone lymphoma of mucosa-associated lymphoid tissue (MALT lymphoma)

Low-grade lymphoma involving cells that arise from the marginal zone surrounding lymphoid follicles.

23%–48% of all primary GI NHLs, second only to DLBCL in most series

ENMZLs are heterogeneous lymphomas, often containing monocytoid-like cells, plasma cells, and scattered large cells intermixed with marginal zone cells.

There are small cells with irregular cleaved nuclei and a moderate amount of clear cytoplasm

DLBCL

Microscopic Appearance  diffuse sheets of large lymphoid cells infiltrate the lamina propria and submucosa, with frequent obliteration of the muscularis propria and ulceration of the overlying mucosa.

Irregular nuclei, prominent nucleoli, and basophilic cytoplasm and are more than twice as large as normal lymphocytes.

Other less common type is  Mantle cell lymphoma
