Question:
A radiotherapist prescribes a new drug combination of chemotherapy and immunotherapy for metastatic melanoma. It prolongs the survival. Which of the following is true in this situation? 

Options:
{'A': 'Incidence reduces and prevalence increases', 'B': 'Incidence remains the same and prevalence increases', 'C': 'Incidence reduces and prevalence remains the same', 'D': 'Incidence increases and prevalence reduces'}'

[2025-09-30T07:47:43.191615] [PI reasoning] **Analyzing epidemiology concepts**

I’m tackling a conceptual epidemiology question that doesn’t require extensive literature. I want to include relevant citations, like Gordis, 2020, with in-text references. The scenario describes a new treatment for metastatic melanoma that improves survival rates, which increases prevalence but keeps incidence the same. The correct answer here is B: incidence remains the same while prevalence increases. I’ll make sure to provide a brief rationale and a citation to support my answer.
