Systems and methods for treating, diagnosing and predicting the occurence of a medical condition

Methods and systems are provided that use clinical information, molecular information and computer-generated morphometric information in a predictive model for predicting the occurrence (e.g., recurrence) of a medical condition, for example, cancer. In an embodiment, a model that predicts prostate cancer recurrence is provided, where the model is based on features including seminal vesicle involvement, surgical margin involvement, lymph node status, androgen receptor (AR) staining index of tumor, a morphometric measurement of epithelial nuclei, and at least one morphometric measurement of stroma. In another embodiment, a model that predicts clinical failure post prostatectomy is provided, wherein the model is based on features including biopsy Gleason score, lymph node involvement, prostatectomy Gleason score, a morphometric measurement of epithelial cytoplasm, a morphometric measurement of epithelial nuclei, a morphometric measurement of stroma, and intensity of androgen receptor (AR) in racemase (AMACR)-positive epithelial cells.

Methods for predicting prostate cancer recurrence

The present invention relates to the identification of four cytokine biomarkers in prostatic tissue that exhibit differential expression following prostatectomy that, in combination at least one other factor, are able to reliably predict the development of biochemical recurrence following surgery. This marker combination improves the risk stratification of patients after primary local treatment for localized prostate cancer.

Combined intra-rectal optical-MR and intra-rectal optical-US device for prostate-, cevix-, rectum imaging diagnostics

We present, in exemplary embodiments of the present invention, a system combining optical imaging technologies with anatomical imaging technologies (e.g., MR, ultrasound). The system can be used for a variety of applications, including, but not limited to, (1) cancer diagnosis and staging; (2) image guidance; and (3) radiation therapy planning. Image guidance may include guiding a biopsy. For example, a prostatectomy potentially has severe side effects, such as impotence and incontinence. Thus, a histologically-confirmed diagnosis, such as one provided from a biopsy, may prevent unnecessary prostatectomy. Image guidance may also include guiding minimal invasive therapy, such as brachytherapy focused ultrasound. The present invention may be used to plan radiation therapy, for example, by detecting, and thus sparing, healthy tissue from radiation exposure.
