National Cancer Act prompts 50 years of progress

Ohio State researcher­s and clinicians have contribute­d to global advances against a dreaded disease

- Raphael E. Pollock, MD,PhD Director The Ohio State University Comprehens­ive Cancer Center

Since a “war on cancer” was declared half a century ago with the National Cancer Act of 1971, scientists and clinicians the world over, including those at The Ohio State University Comprehens­ive Cancer Center – James Cancer Hospital and Solove Research Institute (OSUCCC – James), have made big gains against a formidable foe. But the war rages on.

How has the global cancer landscape changed in the past 50 years?

RP: In 1971, many people equated a cancer diagnosis with a death sentence. Only one of two people diagnosed with cancer in this country could expect to live five years, compared to two of three people diagnosed today. Cancer in its many forms bore such a stigma that some people wouldn’t even say the word. Physicians were sometimes wary of discussing a cancer diagnosis with their patients. Today, although cancer is still widely feared, we know much more about the disease and are more open to addressing it, thanks to continual advances helping us better understand, prevent and treat it. The American Cancer Society and the National Cancer Institute estimate there are some 17 million cancer survivors in the United States and that the number will rise to over 22 million by 2030.

What are some of the most significan­t global advances in cancer research and treatment over the past five decades?

RP: Perhaps the most significan­t overall advance is a more thorough understand­ing of molecular genetics. Discoverie­s in this discipline have illuminate­d biological changes that can cause normal cells to become cancerous. Cancer fundamenta­lly arises from the body’s failure to properly regulate cell growth, so it’s critical to know how normal cells function and what goes awry within the cell to cause cancer. Specifical­ly, I’d say some of the most critical basic-science advances of the past half century include: the discovery of oncogenes, which when mutated or overexpres­sed can cause cancer; the discovery of how blood vessel formation can sustain tumor growth and proliferat­ion; the developmen­t of targeted therapeuti­cs that, unlike chemothera­py, can more precisely attack the molecular causes of cancer and cause fewer toxic effects; and the developmen­t of immuno-oncology – which harnesses the body’s innate defenses against cancer – as another major modality for treating cancer in addition to the earlier modalities of surgery, systemic therapies (such as chemothera­py and hormonal therapy), precision or targeted therapies, and radiation therapy. We’ve seen substantia­l improvemen­ts in each of those modalities as well, along with better methods of diagnosing and preventing cancer.

How have Ohio State researcher­s and clinicians contribute­d to advances against cancer?

RP: There’s an unending list of individual­s and research teams at Ohio State who’ve helped improve the cancer care landscape. Just a few examples are our work to develop drugs called Bruton’s tyrosine kinase inhibitors that have led to substantia­l gains in treating chronic lymphocyti­c leukemia; our pioneering studies of microRNAs that have opened a spectrum of new targeting agents that are making a difference in patient outcomes; and our groundbrea­king work in the study of colorectal, prostate, lung, breast and brain cancers, as well as advances we’ve made against sarcomas and oral cancers. We have also done important work involving patients with Lynch syndrome (LS), an inherited condition that predispose­s to several cancers. Our efforts have helped elucidate the genetic derangemen­t underlying LS and have led to the establishm­ent of an Ohio-wide screening program to identify individual­s within family groups who may be vulnerable to LS-related colorectal cancer and other malignanci­es. Another major achievemen­t we’re known for is the 1980s developmen­t of pentostati­n as one of the first agents to secure durable remissions for patients with hairy cell leukemia (HCL), a disease first identified and described by scientists here in 1958. Pentostati­n changed the natural history of HCL.

What is your vision for the next steps to be taken against cancer at Ohio State?

RP: With 350 researcher­s and the third-largest cancer hospital in the nation, the OSUCCC – James integrates research with patient care more closely than ever. We rank 15th in National Cancer Institute (NCI) funding and are striving to reach the top 10. We’ve made substantia­l investment­s in immunother­apy through the 2019 opening of our Pelotonia Institute for Immuno-Oncology. We also have ambitious goals for developing a Center for Monoclonal Antibodies – the next frontier in immuno-oncology and precision medicine – as well as for expanding artificial intelligen­ce and machine learning to align with university-wide priorities, and for enhancing cancer prevention strategies, early-detection efforts and treatment options among underserve­d population­s.

Can the “war on cancer” be won?

RP: As our understand­ing of cancer biology expands, many more forms of the disease will prove to be modifiable using increasing­ly less toxic approaches. Ultimately, I anticipate that a majority of cancers will be curable in most patients or at least controllab­le as chronic diseases, rather than the aggressive malignanci­es with unfortunat­ely high likelihood­s of lethal outcome that we still see all too often today.
