Question

The following are true about bronchogenic carcinoma EXCEPT

• A. It is the commonest malignant tumour in men
• B. One-Lung-Anaesthesia has improved results of surgery
• C. Most lung cancers are unresectable at presentation
• D. Small cell carcinoma carries better survival rate

Hint:

Small cell lung cancer spreads early and has a poor survival rate, not a better one.

Answer 1

The Correct Option is D

Step 1: Understanding the Question:
The question lists four statements about bronchogenic (lung) carcinoma and asks which one is false.

Step 2: Key Formula or Approach:
Check each statement against how lung cancer actually behaves, in terms of how common it is, how it is treated, and how the different cell types behave.

Step 3: Detailed Explanation:
Lung cancer is indeed the commonest cancer and a leading cause of cancer death in men in many countries, so this statement is true.
One-Lung-Anaesthesia, where only one lung is ventilated during chest surgery, gives the surgeon a still, deflated lung to work on, and this has genuinely improved outcomes of lung resection surgery, so this statement is also true.
Most patients with lung cancer are diagnosed late, once the tumour has already spread locally or to distant sites, so a majority of cases are indeed unresectable at the time of diagnosis, making this statement true as well.
Small cell carcinoma, however, grows fast and spreads early, so it is often already metastatic by the time it is found, and even though it responds well to chemotherapy and radiotherapy, its long term survival remains markedly worse than most non small cell lung cancers.
Calling small cell carcinoma's survival rate "better" is therefore false, which makes it the exception the question is asking for.

Step 4: Final Answer:
Small cell carcinoma does not carry a better survival rate, so this is the false statement.
