Abstract
Methods of determining risk of recurrence of a breast cancer of a subject are provided. Also provided are methods of predicting responsiveness to a therapy of a breast cancer of a subject. Additionally, methods of recommending treatment for a subject that has breast cancer are provided. Further provided are methods of treating a subject that has breast cancer. Systems for performing described methods are also provided.
Claims19
A method of treating breast cancer of a subject who is lymph node-positive, the method comprising
- (i) determining that the subject has a BCIN+numerical score above 7 by:
- assaying or having assayed a sample of breast cancer cells from the subject for the expression levels of BUB1B, CENPA, NEK2, RACGAP1 and RRM2;
- summing or having summed the expression levels of BUB1B, CENPA, NEK2, RACGAP1 and RRM2 as a single index into a subject's MGI index;
- assaying or having assayed the sample of breast cancer cells from the subject for the expression levels of HOXB13 and IL17BR;
- calculating or having calculated the ratio of the expression levels of HOXB13/IL17BR to obtain the subject's H/I ratio;
- summing or having summed the subject's H/I ratio with the subject's MGI index to obtain a subject's BCI numerical score;
- determining or having determined one or more clinicopathological factor selected from tumor size and grade of the subject's breast cancer;
- and
- calculating or having calculated the BCIN+numerical score of the subject by combining the BCI numerical score with the one or more clinicopathological factor of the subject using a multivariate Cox-proportional model;
- and
- (ii) treating the subject with
- (a) endocrine therapy, if the subject has previously been treated for breast cancer, or
- (b) paclitaxel with 5-fluorouracil, doxorubicin and cyclophosphamide, if the subject has not previously been treated for breast cancer.
A method of treating breast cancer of a subject who is lymph node-positive, the method comprising
- (i) determining that the subject has a BCIN+numerical score above a BCIN+numerical score cut point by:
- assaying or having assayed a sample of breast cancer cells from the subject for the expression levels of BUB1B, CENPA, NEK2, RACGAP1 and RRM2;
- summing or having summed the expression levels of BUB1B, CENPA, NEK2, RACGAP1 and RRM2 as a single index into a subject's MGI index;
- assaying or having assayed the sample of breast cancer cells from the subject for the expression levels of HOXB13 and IL17BR;
- calculating or having calculated the ratio of the expression levels of HOXB13/IL17BR to obtain the subject's H/I ratio;
- summing or having summed the subject's H/I ratio with the subject's MGI index to obtain a subject's BCI numerical score;
- determining or having determined one or more clinicopathological factor selected from tumor size and grade of the subject's breast cancer;
- calculating or having calculated the BCIN+numerical score of the subject by combining the BCI numerical score with the one or more clinicopathological factor of the subject using a multivariate Cox-proportional model;
- comparing or having compared the BCIN+numerical score of the subject to the BCIN+numerical score cut point pre-determined based on the BCIN+numerical scores calculated for a training set of samples containing breast cancer tissues from patients that were responsive to endocrine therapy and patients that were not responsive to endocrine therapy;
- and
- (ii) treating the subject with endocrine therapy.
A method of treating breast cancer of a subject who is lymph node-positive, the method comprising
- (i) determining that the subject has a BCIN+numerical score above a BCIN+numerical score cut point by:
- assaying or having assayed a sample of breast cancer cells from the subject for the expression levels of BUB1B, CENPA, NEK2, RACGAP1 and RRM2;
- summing or having summed the expression levels of BUB1B, CENPA, NEK2, RACGAP1 and RRM2 as a single index into a subject's MGI index;
- assaying or having assayed the sample of breast cancer cells from the subject for the expression levels of HOXB13 and IL17BR;
- calculating or having calculated the ratio of the expression levels of HOXB13/IL17BR to obtain the subject's H/I ratio;
- summing or having summed the subject's H/I ratio with the subject's MGI index to obtain a subject's BCI numerical score;
- determining or having determined one or more clinicopathological factor selected from tumor size and grade of the subject's breast cancer;
- calculating or having calculated the BCIN+numerical score of the subject by combining the BCI numerical score with the one or more clinicopathological factor of the subject using a multivariate Cox-proportional model;
- comparing or having compared the BCIN+numerical score of the subject to the BCIN+numerical score cut point pre-determined based on the BCIN+numerical scores calculated for a training set of samples containing breast cancer tissues from patients that had breast cancer recurrence and patients that did not have breast cancer recurrence;
- and
- (ii) treating the subject with endocrine therapy if.
