Abstract
The present invention provides nomograms and methods or predicting survival probabilities for patients diagnosed with metastatic pancreatic cancer based upon patient characteristics such as neutrophil to lymphocyte ratio, albumin level, Karnofsky performance status, the sum of the longest diameter of target lesions, liver metastasis, previous Whipple procedure, treatment with nab-paclitaxel, and analgesic use. In some aspects, the nomograms or methods are implemented by a non-transitory computer-readable storage medium.
Claims22
A nomogram for determining a survival probability of an individual having metastatic pancreatic cancer, the nomogram comprising:
- one or more factor scales comprising values for one or more factors;
- a points scale comprising points values;
- a total points scale comprising total points values;
- and
- a prediction scale;
- wherein the one or more factor scales are correlated with the points scale and wherein the total points scale is correlated with the prediction scale,
- wherein in response to receiving values for the one or more factors, correlating the values for the one or more factors with the points scale to determine one or more points values, combining the one or more points values to determine a total points value, correlating the total points value with the prediction scale, and outputting a survival probability based on the prediction scale.

A method to predict a survival probability of an individual diagnosed with metastatic pancreatic cancer comprising
- receiving values for one or more factors for an individual;
- determining a separate points value for each of the one or more factors based upon one or more factor scales that are correlated with a points scale;
- combining each of the separate point values together to yield a total points value;
- and
- correlating the total points value with a prediction scale to predict the survival probability of the individual.
A computer-implemented method to predict a survival probability of an individual diagnosed with metastatic pancreatic cancer comprising:
- receiving one or more input values for one or more factors, wherein the one or more input values are associated with the individual;
- after receiving the one or more input values, determining, for each of the one or more factors, a respective points value based upon a points scale and a respective factor scale correlated with the points scale;
- aggregating the respective point values for the one or more factors to yield a total points value;
- correlating the total points value with a prediction scale to predict the survival probability of the individual;
- and
- providing one or more outputs based on the predicted survival probability of the individual.
