Mitin Lab

Dr. Mitin at a computer

Timur Mitin, M.D., Ph.D. is an associate professor with the Department Radiation Medicine and serves as medical director Tuality/OHSU Cancer Center in Hillsboro, Oregon. Dr. Mitin was born in Moscow, Russia and came to the United States at the age of sixteen.  He received his medical and doctorate degrees from Tufts University and completed his residency training at the Harvard Radiation Oncology Program.

His research and clinical interests are in the treatment of genitourinary malignancies, especially bladder preservation therapy for patients with muscle-invasive bladder cancer. 

clincal research

Advancement of clinical knowledge requires a self-perpetuating loop that consists of clinical trials, evaluation of the adoption of the results of the studies by medical providers, determination of knowledge gaps and barriers to implementation of new evidence, and generation of a new set of clinical trials. 

We are involved in all phases of the Clinical Research Loop.

The major leaps in clinical care are achieved through meticulously designed and executed clinical trials that either prove and disprove a benefit to a new intervention. As a laboratory of Clinical Research in the Department of Radiation Medicine, we study ways to improve the efficacy of radiation therapy –by investigating the role of RT in new areas, questioning the role of RT in other areas, learning to target RT more precisely with novel imaging modalities, determining how RT can be combined with novel systemic agents. Most of our prospective studies are done in collaboration with other departments. 

Below is the list of some of our studies in various phases of design, preparation, patient accrual and analysis:

  • Adjuvant radiation therapy for patients with Dupuytren's Contractures after surgical or enzymatic release of advanced contractures
  • Localization of involved regional lymph nodes with USPIO-MRI in Esophageal Cancer
  • Localization of involved regional lymph nodes with USPIO-MRI in Rectal Cancer
  • Addition of Bladder-directed radiation therapy to Immunotherapy in metastatic bladder cancer
  • Combination of Conventionally and Hypofractionated Radiation Therapy with Immunotherapy in Stage II/III non-operable NSCLC
  • Alternating Electric Fields as an Alternative to Prophylactic Cranial Irradiation in patients with Small Cell Lung Cancer
  • Assessment of effect of Palliative Radiation Oncology (PRADO) clinic model on outcomes of patients with incurable malignancies.

The adoption of results of clinical trials in the real world is not immediate and may be hindered by lack of knowledge, financial and other barriers. We conduct National Cancer Data Base analyses to determine the patterns of treatments and outcomes for common malignancies where standard of care has been established through rigorous clinical trials, as well as rare conditions, in which clinical trials are not possible. 

Below is the list of NCDB projects we have conducted with our colleagues:

  • Rectal Cancer (Cancer Journal)
  • Gallbladder Cancer (Lancet)
  • Breast Angiosarcoma

Despite clinical evidence from published clinical trials, the daily practice of medicine by providers may be in a stark contrast to established guidelines. Large retrospective population-based analysis cannot capture the most current views and practices of treating physicians. Survey-based analysis of current patterns of treatment, with evaluation of association of respondents' characteristics, knowledge base, allows us to determine the future direction for clinical trials.

Some of our survey-based analysis work is presented below:

  • Seminoma   
  • ES-SCLC   
  • LS-SCLC   
  • Prostate   
  • Breast Angiosarcoma   
  • Esophagus   
  • Bladder   
  • Rectal cancer

The Russian Society of Clinical Oncology (RUSSCO) has written practical recommendations of the Russian Society of Clinical Oncology for the provision of cancer care in the context of the COVID-19 pandemic. These recommendations were created due to the need for cancer care in a pandemic and the maximum protection of patients and medical personnel. Timur Mitin, M.D., Ph.D., associate professor and medical director of the Tuality OHSU Cancer Center, took part in writing and discussing these recommendations.

Timur Mitin, M.D., Ph.D. is co-PI of CRUK (Cancer Research UK)-OHSU/Cancer Early Detection Advanced Research Center (CEDAR) Spark Award for his proposal titled "Amplicon deep sequencing of urinary DNA for the early detection of recurrence following chemoradiotherapy for muscle-invasive bladder cancer ("AmpseqUr-RT"). The $20,000.00 grant award is based upon the novel hypothesis that earlier detection of recurrence in patients with muscle-invasive bladder cancer who have undergone chemoradiotherapy. As such, Dr. Mitin and his team will assess the diagnostic utility of AmpseqUR in this setting. AmpseqUr utilizes the commonest urothelial bladder cancer-associated somatic mutations and amplifies the loci of interest by multiplex PCR and identifies mutations by targeted next-generation sequencing of the amplicons.
