Task: Answer Verification
Input (English): Question: Does recursive partitioning analysis ( RPA ) class predict survival in patients with four or more brain metastases?
Answer: Patients with four or more brain metastases seem to represent a group with unfavorable prognosis where remission of brain metastases or administration of more than 30 Gy were not associated with increased survival. The number of patients in RPA class I was too small to draw final conclusions. However, there was absolutely no survival difference between patients in class II (median survival 3.6 months) and III (median 4.2 months).
Output (English): no
