Education

Theodorescu earned a medical degree from Queen's University at Kingston in 1986, followed by a doctorate from the University of Toronto in 1991. His post degree training was a residency in urology from the University of Toronto in 1994 and a fellowship in urologic oncology at Memorial Sloan Kettering Cancer Center in 1995. [1]

Memberships

Theodorescu is an elected member of the American Society for Clinical Investigation, Association of American Physicians, the American Association of Genitourinary Surgeons, the American Surgical Association, and the National Academy of Medicine. [4] [3]

He is an Honorary Fellow of the American Association for the Advancement of Science. [5] He is also a founding co-editor in chief of the journal Bladder Cancer . [6]

Research

Theodorescu is known for his work on the molecular mechanisms driving bladder cancer, discovery of tools that determine drug response and new therapeutics. Examples of his research include examining genes that regulate tumor growth and metastasis such as RhoGDI2 [7] [8] and biomarkers and approaches to precision medicine. [9] [10] [11] He led the work on the “first in class” RalGTPase inhibitor as a new therapeutic in cancer. [12] He has published work showing DDR2 as a target for effective combination immunotherapy with checkpoint inhibitors [13] and the presence of a new cellular subtype in bladder tumors, called “C3”, shown to predict response to immune checkpoint therapy.

Bladder cancer is any of several types of cancer arising from the tissues of the urinary bladder. Symptoms include blood in the urine, pain with urination, and low back pain. It is caused when epithelial cells that line the bladder become malignant.

Immunotherapy or biological therapy is the treatment of disease by activating or suppressing the immune system. Immunotherapies designed to elicit or amplify an immune response are classified as activation immunotherapies, while immunotherapies that reduce or suppress are classified as suppression immunotherapies. Immunotherapy is under preliminary research for its potential to treat various forms of cancer.

Kidney cancer, also known as renal cancer, is a group of cancers that starts in the kidney. Symptoms may include blood in the urine, a lump in the abdomen, or back pain. Fever, weight loss, and tiredness may also occur. Complications can include spread to the lungs or brain.

<span class="mw-page-title-main">Melanoma</span> Cancer originating in melanocytes

Melanoma, also redundantly known as malignant melanoma, is a type of cancer that develops from the pigment-producing cells known as melanocytes. Melanomas typically occur in the skin, but may rarely occur in the mouth, intestines, or eye. In women, they most commonly occur on the legs, while in men, they most commonly occur on the back. About 25% of melanomas develop from moles. Changes in a mole that can indicate melanoma include an increase in size, irregular edges, change in color, itchiness, or skin breakdown.

<span class="mw-page-title-main">Sentinel lymph node</span> First lymph node to receive drainage from a primary tumor

The sentinel lymph node is the hypothetical first lymph node or group of nodes draining a cancer. In case of established cancerous dissemination it is postulated that the sentinel lymph nodes are the target organs primarily reached by metastasizing cancer cells from the tumor.

<span class="mw-page-title-main">Transitional cell carcinoma</span> Medical condition

Transitional cell carcinoma, also called urothelial carcinoma, is a type of cancer that typically occurs in the urinary system. It is the most common type of bladder cancer and cancer of the ureter, urethra, and urachus. Symptoms of urothelial carcinoma in the bladder include hematuria. Diagnosis includes urine analysis and imaging of the urinary tract (cystoscopy). Transitional cell carcinomas arise from the transitional epithelium, a tissue lining the inner surface of these hollow organs. When the term "urothelial" is used, it specifically refers to a carcinoma of the urothelium, meaning a transitional cell carcinomas of the urinary system.

Neoadjuvant therapy is the administration of therapeutic agents before a main treatment. One example is neoadjuvant hormone therapy prior to radical radiotherapy for adenocarcinoma of the prostate. Neoadjuvant therapy aims to reduce the size or extent of the cancer before using radical treatment intervention, thus both making procedures easier and more likely to succeed and reducing the consequences of a more extensive treatment technique, which would be required if the tumor were not reduced in size or extent.

Rho GDP-dissociation inhibitor 2 is a protein that in humans is encoded by the ARHGDIB gene. Aliases of this gene include RhoGDI2, GDID4, Rho GDI 2, and others.

A metastasis suppressor is a protein that acts to slow or prevent metastases from spreading in the body of an organism with cancer. Metastasis is one of the most lethal cancer processes. This process is responsible for about ninety percent of human cancer deaths. Proteins that act to slow or prevent metastases are different from those that act to suppress tumor growth. Genes for about a dozen such proteins are known in humans and other animals.

Scherr was the first physician at Cornell to perform a robotic prostatectomy as well as a robotic cystectomy.

<span class="mw-page-title-main">Brain metastasis</span> Cancer that has metastasized (spread) to the brain from another location in the body

A brain metastasis is a cancer that has metastasized (spread) to the brain from another location in the body and is therefore considered a secondary brain tumor. The metastasis typically shares a cancer cell type with the original site of the cancer. Metastasis is the most common cause of brain cancer, as primary tumors that originate in the brain are less common. The most common sites of primary cancer which metastasize to the brain are lung, breast, colon, kidney, and skin cancer. Brain metastases can occur in patients months or even years after their original cancer is treated. Brain metastases have a poor prognosis for cure, but modern treatments are allowing patients to live months and sometimes years after the diagnosis.

Active immunotherapy is a type of immunotherapy that aims to stimulate the host's immune system or a specific immune response to a disease or pathogen and is most commonly used in cancer treatments. Active immunotherapy is also used for treatment of neurodegenerative disorders, such as Alzheimer's disease, Parkinson's disease, prion disease, and multiple sclerosis. Active immunotherapies induce an immune response through direct immune system stimulation, while immunotherapies that administer antibodies directly to the system are classified as passive immunotherapies. Active immunotherapies can elicit generic and specific immune responses depending on the goal of the treatment. The categories of active immunotherapy divide into:
