The second advancement is a team approach, something he learned the importance of and brought to the Baystate Regional Cancer Program after seeing a patient during his residency in Ontario, Canada. The patient suffered from ovarian cancer but struggled to find the appropriate specialists and had delayed diagnosis and uncoordinated management of complications.
“We have surgical, radiation, gynecologic, medical and hematologic oncologists that care for patients today along with other medical specialists such as gastroenterologists, endocrinologists and many others - everyone has a cancer role to play. Nurses, pharmacists, radiation technologists and care coordinating staff are critical to the delivery of modern, complex cancer care. Cancer is managed by people for people, and it is important to include everyone’s special contribution, knowledge and skills for the betterment of our patients at the right time, in the right setting, for the best outcomes. It has taken a while to achieve, but being

able to offer the best that all our medical specialties can offer in a coordinated fashion is a truly critical advance,” Dr. Mertens said. Coordination efforts abound at Baystate, including patient care coordinators, tumor conferences - there are 10 that meet regularly - and disease-specific treatment teams that enhance care management and knowledge as well as improve patient care flow. Can cancer be prevented? It’s a question that Dr. Mertens said he often hears from patients, noting the answer is that it is all about modifying risk factors to lower your chances of developing cancer. “Aside from genetics and family history which are not modifiable, avoiding tobacco and limiting alcohol use, not being overweight, keeping physically active, protecting yourself from the sun, practicing safe sex and other healthy lifestyles can reduce your cancer risk. The campaign to stop smoking has been somewhat successful, reducing cancer deaths over the years, but we haven’t made strides in areas such as obesity or getting people off the couch. Most cancer screenings such as mammograms or those for prostate or lung cancer do not prevent cancer, but detect cancer earlier so that treatment can more effectively reduce mortality. However, screening colonoscopy can prevent cancer because if a polyp is found, it can be removed and prevent it from turning cancerous,” Dr. Mertens said. “From a population perspective, we continue to make slow but steady progress to discontinue the use of tobacco and reduce alcohol consumption while obesity is going in the opposite direction. We are now seeing the price of obesity and an unhealthy diet in terms of increasing rates of colorectal cancer in younger people under 45. And, there is still a great deal of work to do on increasing physical activity which both improves cancer outcomes as well as impact-
ing other conditions such as heart and vascular disease,” he added. As for the future, the Baystate cancer specialist noted promising work that may play a major role in cancer identification and treatment, as well as areas that must be addressed in prevention. “In addition to work on cancer causing genes, such as the BRCA1 and 2 genes that cause inherited breast and ovarian cancer syndrome, and genes that are associated with other inherited cancer syndromes, there is increasing research still in its infancy on infectious agents as causes of cancer. Scientific study in this area may offer interesting results in the next 10-15 years including clarifying the role of bacteria in our bowels - the gut microbiome -in cancer causation and management,” Dr. Mertens said. More work also needs to be done to improve the quality of life for cancer patients and their families. He agrees with the World Health Organization’s assessment that effective health strategies, comprising community- and home-based care, are essential to provide pain relief and palliative care, which is treatment to relieve, rather than cure, symptoms and suffering caused by cancer. “Cancer care has been revolutionized over the past 50 years, but our community and home care models have not kept pace with this rapid change. Care provider organizations and health insurance entities will have to make significant strides to modernize and remain relevant to patients and families facing complex care challenges,” Dr. Mertens said.
