Prognostic Index of Vincent et al for Small Cell Lung Cancer

 

Parameters:

(1) ECOG performance scale

(2) serum albumin

(3) serum ALT

(4) liver scan

 

Criteria for good prognostic group - all of the following:

(1) ECOG performance scale 0 or 1

(2) serum ALT normal

(3) serum albumin >= 3.6 g/dL

(4) normal liver scan

 

Criteria for intermediate prognosis - 1 or 2 of the following:

(1) ECOG performance scale 2

(2) elevated serum ALT

(3) serum albumin 3.0 to 3.5 g/dL

(4) abnormal liver scan indicative of metastatic disease

 

Criteria for poor prognosis: anyone who is not classified as having a good or intermediate prognosis

 

Features that tend to be found in a patient with poor prognosis (not covered in the previous groups):

(1) serum albumin < 3.0 g/dL

(2) ECOG performance scale 3 or 4
