Free oncosurgery MCQ exam model for clinical students

Explanation:

• Before surgery → Correct because neoadjuvant therapy reduces tumor size preoperatively.

• After surgery → Incorrect because this is adjuvant therapy.

• During surgery → Incorrect because therapy is not administered intraoperatively.

• Only for recurrence → Incorrect because it is used in primary disease.

• Only in metastatic disease → Incorrect because it is used in locally advanced disease.

Explanation:

• Surgical management of cancer → Correct because oncosurgery focuses on operative removal of tumors.

• Medical treatment of cancer → Incorrect because this is medical oncology.

• Radiation treatment of tumors → Incorrect because this is radiation oncology.

• Genetic counseling → Incorrect because this is preventive oncology.

• Chemotherapy administration → Incorrect because this is medical oncology.

Explanation:

• Tumor stage → Correct because extent of disease determines surgical feasibility.

• Patient age → Incorrect because age alone is not a contraindication.

• Tumor grade → Incorrect because grade affects prognosis, not operability.

• Tumor marker level → Incorrect because it is adjunctive.

• Patient gender → Incorrect because it has no role.

Explanation:

• Infection → Correct because immunosuppression and extensive surgery increase risk.

• Anastomotic leak → Incorrect because it is procedure-specific.

• Bleeding → Incorrect because it is usually controlled intraoperatively.

• Deep vein thrombosis → Incorrect because it is important but less common than infection.

• Organ failure → Incorrect because it is uncommon in routine cases.

Explanation:

• Breast cancer → Correct because it assesses axillary nodal spread minimally invasively.

• Lung cancer → Incorrect because mediastinoscopy is used.

• Colorectal cancer → Incorrect because lymphadenectomy is standard.

• Pancreatic cancer → Incorrect because nodal spread is extensive.

• Esophageal cancer → Incorrect because radical nodal dissection is needed.

Explanation:

• Complete tumor removal with negative margins → Correct because margin status determines recurrence risk.

• Cosmetic outcome → Incorrect because oncologic clearance is priority.

• Minimal incision → Incorrect because adequate exposure is necessary.

• Shortest hospital stay → Incorrect because it is secondary consideration.

• Avoiding lymph node dissection → Incorrect because nodal assessment is often essential.

Explanation:

• Removal of tumor with adequate surrounding normal tissue → Correct because it ensures negative margins.

• Removal of tumor only → Incorrect because margins may be positive.

• Removal of tumor with minimal margin → Incorrect because it increases recurrence risk.

• Removal of entire organ → Incorrect because this is radical surgery.

• Removal of lymph nodes only → Incorrect because primary tumor remains.

Explanation:

• Remove tumor completely with margins → Correct because complete excision reduces recurrence.

• Relieve pain → Incorrect because this is palliative intent.

• Confirm diagnosis only → Incorrect because biopsy is diagnostic, not definitive surgery.

• Prevent metastasis medically → Incorrect because surgery is local treatment.

• Improve immunity → Incorrect because surgery does not enhance immunity.

Explanation:

• Wide local excision → Correct because early tumors are treated with curative excision.

• Debulking surgery → Incorrect because it is used in advanced disease.

• Radical surgery → Incorrect because it removes entire organ and is less common now.

• Palliative surgery → Incorrect because it is non-curative.

• Bypass surgery → Incorrect because it relieves obstruction only.

Explanation:

• Relieve obstruction → Correct because palliative surgery aims to improve quality of life.

• Cure cancer → Incorrect because palliative surgery is non-curative.

• Reduce tumor size for chemotherapy → Incorrect because this is neoadjuvant intent.

• Prevent recurrence → Incorrect because recurrence prevention is curative intent.

• Improve immune response → Incorrect because surgery does not enhance immunity.
