Abstract: Patients who have their cancer surgically removed are at risk for recurrence, even though currently free of disease. Lung cancer patients with higher activity of a nuclear excision repair gene called ERCC1 were at a lower risk for recurrence than patients with lower activity of ERCC1. Hence, it is possible to predict which patients are at a higher risk for recurrence after resection. This information can be used to design treatment strategies for patients determined to be at a higher risk for recurrence. Additionally, patients who are lower risk for recurrence can be saved the morbidity of further treatment.

Abstract: Methods are provided for predicting responsiveness of cancer cells to chemotherapy by measuring the level of phosphorylated Stat or the level of expression of Survivin in a cancer and comparing the level in the cancer cell to the respective level in a control. Also provided are methods of selecting a chemotherapeutic treatment for a subject diagnosed with cancer by measuring the level of phosphorylated Stat or the level of expression of Survivin in a cancer and comparing the level in the cancer cell to the respective level in a control. Kits for performing the methods are also provided. Methods for modulating Survivin-dependent apoptosis in a cancer cell are also disclosed.

Abstract: The invention relates to methods of determining an appropriate cancer therapy for a subject based on intratumoral expression levels of Ribonucleotide Reductase M1 (RRM1) and thymidylate synthase (TS) gene expression, as well as to methods of predicting clinical outcome (prognosis) based on cytoplasmic levels of TS protein. Compositions and kits useful for the methods are also provided.

Abstract: The present invention provides a method for detection of loss of heterozygosity (LOH) at human chromosome segment 11p15.5 in a tumor sample from a patient with non-small-cell lung cancer (NSCLC), and a method for prognosis of the patient's disease progression. The prognosis is useful for determining the course of treatment following surgical resection of tumor.

Abstract: The present invention relates to methods for determining and/or predicting the phenotype of a cancer or precancerous tissue. In certain embodiments, the methods described herein relate to predicting of survival of a subject with a cancer or a precancerous tissue, predicting response to therapy of a subject with a cancer or precancerous tissue, predicting metastasis of a cancer in a subject, predicting recurrence of cancer in a subject, or predicting the progression of a precancerous tissue to cancer. The present invention further relates to kits for determining and/or predicting the phenotype of a cancer or a precancerous tissue.
