Lung Tumors MCQs: practice questions

Sample Lung Tumors multiple-choice questions from Respiratory.

Solitary pulmonary nodules found incidentally on imaging require evaluation primarily to exclude which possibility?
- A. A process with no clinical significance in any case
- B. mainly infectious causes, with malignancy rarely a consideration
- C. mainly vascular malformation, with few other differentials
- D. A finding requiring no further workup regardless of size or characteristics
- E. Malignancy
Squamous cell carcinoma of the lung is classically associated with which paraneoplastic syndrome, through PTHrP secretion?
- A. SIADH mainly
- B. Hypercalcemia of malignancy
- C. Cushing syndrome mainly
- D. Lambert-Eaton myasthenic syndrome mainly
- E. Carcinoid syndrome mainly
Which best explains why non-small cell lung carcinomas are generally treated with surgical resection when feasible, unlike small cell carcinoma?
- A. Non-small cell carcinomas are rarely amenable to surgical treatment
- B. NSCLC often localized/resectable; less chemo-responsive
- C. Small cell carcinoma is commonly more localized at diagnosis
- D. Surgical resection has no role in any lung cancer subtype
- E. Non-small cell carcinomas are commonly found at a metastatic stage
Which best distinguishes a bronchial carcinoid tumor histologically from small cell carcinoma, despite their shared neuroendocrine origin?
- A. The two tumors are histologically comparable in most respects
- B. Small cell carcinoma commonly shows a lower mitotic rate than carcinoid
- C. Carcinoid tumors show a low mitotic rate and lack the necrosis typical of small cell carcinoma
- D. Carcinoid tumors commonly show extensive necrosis comparable to small cell carcinoma
- E. Neither tumor shows any neuroendocrine markers on staining
Which is the single most important risk factor for lung cancer overall?
- A. Isolated genetic predisposition with no environmental contribution
