Define the role of immune response on radiation therapy outcomes in patients with HPV-associated gynecologic cancers. A currently ongoing trial is evaluating serial changes in the immune response during radiation therapy in patients with cervical cancer treated with standard of care approach or HPV direct vaccine coupled with chemoradiation. Small volume samples are used for multi-spectral flow cytometry, T-cell receptor sequencing, whole exome sequencing and function expansion assays to characterize the impact of radiation on immune activation.

We have identified microbiome signatures associated with toxicity and survival in patients with HPV cancers. Investigations into how to manipulate the microbiome to improve outcomes are under development.

Determining the role of MRI guidance in brachytherapy for cervical cancer. We have developed clinical trials aimed at optimizing brachytherapy for cervical cancer, progressing from comparison with CT to MRI to incorporating active MRI guidance into gynecologic brachytherapy using hybrid applicators.

Refine the role of radiation therapy for gynecologic cancers including treatment of oligometastatic cancers. We have reported on our own experience with definitive RT to metastatic disease leading to long term survival.  I led the phase III randomized trial RTOG 1203/TIME-C demonstrated that IMRT reduced patient reported toxicity. We found that bone marrow dose is predictive of hematologic toxicity from bone marrow radiation. We reported on the outcomes of patients treated with paraaortic IMRT, which led to the recognition of duodenal toxicity in these patients. In subsequent analyses, we identified a dosimetric parameter predictive of duodenal toxicity.

We found that adipose-derived stromal cells from visceral and omental adipose have a unique phenotype and mediate the tumor promoting effects of adipose on cancer. adipose-derived stromal cells promote the migration and chemoresistance of ovarian cancers. We were the first group to characterize adipose-derived stromal cells from the visceral adipose. We found that omental adipose-derived stromal cells more potently promoted tumor growth than subcutaneous or bone marrow-derived stromal cells in a murine endometrial cancer model. We determined that obesity changes the phenotype of adipose-derived stromal cells, identifying a novel mechanism by which obesity supports growth of ovarian cancers.
