Question 1 (part 2) · LEK · Lung cancer
Which of the following statements are true?
1) lung abscess might be a result of central necrosis of a tumour, typically adenocarcinoma;
2) lung adenocarcinoma develops in the peripheral parts of the lung;
3) the risk of developing small-cell carcinoma is loosely linked with smoking, contrary to the risk of developing squamous cell carcinoma;
4) in a patient with lung cancer, unilateral diminished breath sounds might result not only from pleural effusion but also from atelectasis caused by ipsilateral bronchial obstruction or phrenic nerve palsy;
5) appropriate laryngological and neurological evaluation suffices in the diagnosis of hoarseness caused by non-infectious factors and Horner’s syndrome;
6) the course of lung cancer might be accompanied by an increase in carcinoembryonic antigen (CEA) in the blood serum.
The correct answer is:
2) lung adenocarcinoma develops in the peripheral parts of the lung;
3) the risk of developing small-cell carcinoma is loosely linked with smoking, contrary to the risk of developing squamous cell carcinoma;
4) in a patient with lung cancer, unilateral diminished breath sounds might result not only from pleural effusion but also from atelectasis caused by ipsilateral bronchial obstruction or phrenic nerve palsy;
5) appropriate laryngological and neurological evaluation suffices in the diagnosis of hoarseness caused by non-infectious factors and Horner’s syndrome;
6) the course of lung cancer might be accompanied by an increase in carcinoembryonic antigen (CEA) in the blood serum.
The correct answer is:
- A. 1,2,3,5.
- B. 1,3,4,5.
- C. 4,5,6.
- D. 2,4,6.
- E. all the above.
Hint
Recall which histological type cavitates centrally, where adenocarcinoma usually arises and how strongly small-cell cancer depends on smoking.
