Dr. Jeremy S. Kortmansky, a medical oncologist and hematologist at MOH’s Hamden Surgery & Medical Center facility, has been fascinated by the science of hematology and oncology since the earliest days of his medical training. "The pathways gone awry and the new treatments in development continually piqued my interest," he says. "When my own mother died of breast cancer, I experienced the real impact of the disease. This field enables me to combine my love of science with my commitment to a strong physician-patient partnership." Dr. Kortmansky was initially attracted to MOH by the caliber of MOH’s physicians. "They are motivated, friendly, attentive, and trained through nationally recognized cancer programs," he says. He also likes the close physician-patient relationships he found at MOH. "We remain one of the few physician practices that see our own patients when they are hospitalized, and we provide 24-hour coverage for our patients. I also know that cancer care is a coordinated effort and I am particularly impressed by our access to the newest technology and superbly qualified physicians in the other medical, surgical and radiology fields. It is truly rare to find this depth and breadth of quality in a community-based practice." Skilled in the treatment of all forms of cancer and blood diseases, Dr. Kortmansky has a particular interest and expertise in caring for patients with cancers of the gastrointestinal system, including esophageal, gastric, hepatobiliary, pancreatic, colorectal, and neuroendocrine tumors. Dr. Kortmansky is encouraged by the many advances in cancer care of recent years and has great hope for what the near future promises. "In the past 10 years," he says, "we have learned that cancers are not defined merely by where they originated or how they look under the microscope. We know that differences at the molecular level control how they behave and how they respond to treatment. In the next 10 years, I expect treatments to be determined based on these molecular pathways, optimizing the benefits of a therapy, improving survival, and reducing costs." Fascinated by all these scientific advances, Dr. Kortmansky never loses sight of the human needs the science is serving. "My objective in providing cancer care," he says, "is to allow patients to continue to do the things they enjoy and find a little laughter. Cancer can be an all-consuming entity, if we let it. But I strive to help patients live a good life with their cancer rather than be held captive by it." When not at work, Dr. Kortmansky enjoys spending time with his wife and two children, biking, and gardening.
