- Personal Statement
As a surgeon-scientist, I specialize in the comprehensive surgical management of patients with cancer, pathology, pain, and trigeminal nerve injury. My research and clinical programs are closely integrated, and my research addresses the many challenges I face in the clinical management of patients with a focus on cancer management and treatment. As the director and principal investigator of the LITElab (Lam Innovation Translation Education) within Stony Brook School of Dental Medicine, I lead a team of clinicians and scientists dedicated to solving challenging clinical problems using innovative research and knowledge translation techniques.

- Current research aims to discover novel mediators of cancer pain, such as TMPRSS2. Following are significant research contributions (as of November 2017):
- A. Discovery of new cancer pain pathway. Pain is one of the problems that patients suffering with cancer fear most. Cancer often produces severe pain and dysfunction secondary to mechanical hypersensitivity in humans. Following the rapid development of opioid tolerance, there are no pharmacologic agents available to treat intractable cancer pain. A major obstacle to the effective treatment of cancer pain is that the mediators involved in the generation of pain in patients with cancer are poorly understood. Using a combined molecular, pharmacologic, behavioral, and genetic approach, my colleagues and I identified a novel mechanism of cancer-mediated pain induced by serine proteases and the protease-activated receptor 2 (PAR2) (Serine proteases and protease-activated receptor 2-dependent allodynia: a novel cancer pain pathway). This previously unrecognized cancer pain pathway has important therapeutic implications wherein serine protease inhibitors and PAR2 antagonists may be useful for the treatment of cancer pain. More recently, my colleagues and I discovered a novel role for a cell membrane-anchored serine protease mediator, TMPRSS2, in cancer pain, as well as pain in general (TMPRSS2, a novel membrane-anchored mediator in cancer pain). The startling discovery of TMPRSS2's role in triggering cancer pain may lead to the creation of targeted cancer pain therapies that effectively shut down the expression of this gene or its ability to infiltrate pain receptors in the body.
- B. Development of new head and neck cancer pain preclinical model. This model enables the study of the transition from acute to chronic pain. Targeted therapy to prevent the progression from acute to chronic pain in cancer patients remains elusive. My colleagues and I developed three novel cancer models in mice that together recapitulate the anatomical, temporal, and functional characteristics of acute and chronic head and neck cancer pain in humans (Novel animal models of acute and chronic cancer pain: a pivotal role for PAR2). The impact of this study was recognized as a feature article on the cover of the Journal of Neuroscience, the top journal in the field of neuroscience research. Using pharmacologic and genetic approaches in these novel cancer models, my colleagues and I demonstrated a direct role for PAR2 in acute cancer pain and suggest that PAR2 upregulation may favor the development and maintenance of chronic cancer pain. Targeting the PAR2-serine protease interaction is a promising approach to the treatment of acute cancer pain and prevention of chronic cancer pain.
- C. Challenging a clinical aphorism on cancer: earlier recognition of symptoms of head and neck cancer may improve early detection of the cancer itself. Contrary to a clinical aphorism that early head and neck cancer is painless, my colleagues and I revealed that patients who develop head and neck cancer experience significant pain at the time of initial diagnosis (Orofacial pain onset predicts transition to head and neck cancer). The impact of this study was recognized as a feature article on the cover of Pain, the top journal in the field of pain research. This article was selected as one of three annual special reprints in 2015 in the Ontario Dental Association Journal as part of the Oral Health Strategy, and also highlighted in the Journal of the Canadian Dental Association (JCDA Express Issue 6, 2011). Of the constellation of symptoms, recent onset of significant orofacial pain, particularly if exacerbated during function, may be the best clue and should be included in the clinical assessment of patients to identify a high-risk group to apply screening strategies for early cancer detection. Further investigations into the correlations between pain parameters and the specific biology of head and neck cancer may improve quality of life and survival for head and neck cancer patients.
- D. Innovations in clinical management of oral and maxillofacial pathology. My colleagues and I have developed various innovative approaches to the management (Chadwick et al., 2016; Ledderhof et al., 2017; Caminiti & Lam, 2017) and reconstruction (Lam et al., 2012) of complex oral and maxillofacial pathologies. The impact of this work has been regularly published in the Journal of Oral and Maxillofacial Surgery, the top journal in the OMS field. In particular, I have developed an international reputation for my expertise in the diagnosis and management of trigeminal nerve injuries: presenting over 20 invited lectures and seminars, nationally and internationally, and most recently an invited textbook editorship (Pogrel MA, Lam DK, editors. Practical Approaches to Avoid Trigeminal Nerve Injuries. Springer).
