Abstract

Hepatocellular carcinoma (HCC) is detected in a patient with liver disease. Mass spectrometry data from a blood-based sample from the patient is compared to a reference set of mass-spectrometry data from a multitude of other patients with liver disease, including patients with and without HCC, in a general purpose computer configured as a classifier. The classifier generates a class label, such as HCC or No HCC, for the test sample. A laboratory system for early detection of HCC in patients with liver disease is also disclosed. Alternative testing strategies using AFP measurement and a reference set for classification in the form of class-labeled mass spectral data from blood-based samples of lung cancer patients are also described, including multi-stage testing.

Claims (2682)

1. A method of generating a classifier for detecting HCC in a patient with liver disease, comprising the steps of:

a) conducting MALDI-TOF mass spectrometry on a set of blood-based samples from a multitude of patients with liver disease, including some patients with HCC and some patients without HCC;

b) storing a development set of mass spectrometry data as a result of conducting step a) on the set of blood-based samples, the development set of mass spectrometry data including feature values at a multitude of mass spectral features;

c) assigning a classification label to each member of the development set of step b) based on whether or not the patient associated with the sample had HCC;

d) separating the development set into training and test sets;

e) constructing a multitude of mini-classifiers using one or more of the feature values;

f) filtering the performance of the mini-classifiers operating on the training set and retaining only those mini-classifiers that meet a performance threshold;

g) generating a master classifier by combining the filtered mini-classifiers using a regularized combination method;

h) evaluating the performance of the master classifier on the test set;

i) repeating steps d), e), f), g) and h) for many different realizations of the separation of the development set into training and test sets; and

j) defining a final classifier from the master classifiers resulting from step g) and the repeated iterations of step i).

2. The method of claim 1 , wherein the development set of sample excludes those patients with high AFP expression levels.

3. The method of claim 1 , wherein the feature values include a feature value associated with AFP expression level measured in the blood-based samples of the development set.

4. The method of claim 1 , wherein the filtering step f) includes a sub-step of testing the performance of the mini-classifiers to classify spectra of healthy patients and retaining only those mini-classifiers whose healthy patient classification accuracy exceeds a pre-determined limit.

5. The method of claim 4 , wherein the method further comprises the step of varying the pre-determined limit and assessing master classifier performance with different values of the pre-determined limit.

6. The method of claim 1 , wherein the mini-classifiers implement a K-nearest neighbor algorithm and wherein the value of K is one of 5, 7, 9 and 11.

7. The method of claim 1 , the mini-classifiers perform classifications on the training set using single features, pairs of features, or single features, pairs of features and triplets of features in the set of feature values.

8. The method of claim 1 , wherein the mini-classifiers use at least 50 features in the set of features listed in Tables 1, 2, or 4:
