Advanced MCQ – Lynch Syndrome Surveillance
A 32-year-old woman is diagnosed with Lynch syndrome after genetic testing reveals a pathogenic MSH6 mutation. She has completed childbearing and asks about her cancer risks and recommended surveillance strategy. Which statement is MOST accurate?
  • A. Her lifetime CRC risk exceeds 60%
  • B. Annual colonoscopy beginning at age 40 is appropriate
  • C. Annual transvaginal ultrasound with endometrial biopsy should be considered starting at age 30–35
  • D. Prophylactic hysterectomy is not recommended
  • E. EPCAM mutations do not require colonoscopic surveillance
Correct Answer: C

Explanation:
• Annual colonoscopy begins at age 20–25 in Lynch syndrome.
• Endometrial cancer screening (TVUS + biopsy) starts at age 30–35.
• Prophylactic hysterectomy should be discussed after completion of childbearing.
• EPCAM deletions silence MSH2 and follow MSH2 surveillance guidelines.

Pelvic floor

📘 Theme: Mock Test – 1 March 2026

Pelvic Floor Mechanics

During anorectal manometry, a patient demonstrates preservation of resting continence despite severe internal anal sphincter damage. Which structure is most responsible for maintaining continence in this scenario?

A. Pubococcygeus
B. Iliococcygeus
C. Puborectalis
D. External anal sphincter

Answer: C. Puborectalis

Explanation:
The puborectalis muscle forms a U-shaped sling around the anorectal junction and is the most critical muscle for maintaining fecal continence. Its tonic contraction maintains an acute anorectal angle, preventing involuntary stool passage. Even with internal anal sphincter damage, the puborectalis sling can preserve continence.

Teaching Points:

  • Puborectalis forms a sling at the anorectal junction.
  • Maintains anorectal angle (~80–90°) → continence.
  • Relaxes during defecation → angle straightens.
  • Dysfunction → dyssynergic defecation or fecal incontinence.
  • Key compensatory mechanism when sphincters are weak.

AFP & Embryomal cell carcinoma of Testis

AFP in Pure Embryonal Cell Carcinoma MCQ | mcqsurgery.com
Q) Which of the following statements about alpha-fetoprotein (AFP) in pure embryonal cell carcinoma is most accurate?
✅ Answer: c) AFP is elevated in 50-80% of cases of pure embryonal cell carcinoma.

🔍 Explanation:
Alpha-fetoprotein (AFP) is a **tumor marker** commonly elevated in **non-seminomatous germ cell tumors** (NSGCTs), which includes **embryonal cell carcinoma**. AFP levels are elevated in approximately **50-80%** of cases of **pure embryonal carcinoma**, and this elevation is associated with the **yolk sac tumor component** that is often seen within these tumors.
  • AFP is a **glycoprotein** produced by the fetal liver and yolk sac, and its levels are typically **low in adults**.
  • It is elevated in conditions like **liver cancer**, **germ cell tumors**, and **yolk sac tumors** (which may be seen with embryonal carcinoma).
  • In **seminomas**, AFP is **usually normal**, and they are typically not associated with AFP elevation.
  • Correct interpretation of AFP levels is important for **diagnosis**, **monitoring treatment response**, and **detecting recurrence** in **germ cell tumors**.
Misinterpreting AFP levels can lead to **incorrect staging** or **diagnosis** of testicular cancers.

GCS Intubated patient

by
Multiple MCQs Example | mcqsurgery.com
Q1) What is the maximum possible GCS score for an intubated patient?
Show Answer & Explanation
✅ Answer: c) 11T

🔍 Explanation: In intubated patients, verbal cannot be assessed (T). Max score = Eye 4 + Motor 6 = 10, written as 11T. Explanation and Teaching Points: Intubated patients cannot be assessed for the verbal response, which is replaced by “T”. The verbal component (maximum 5) is omitted, so the best total becomes Eye (4) + Motor (6) = 10, and the notation “T” is added, making it 11T. Regular reassessment (every 30 minutes) is crucial to detect changes in neurological status.
