New Cancer Tests Cut Treatment Side Effects at Penn State

When Wendy Jackson opened her mouth at the dentist, one look told her something was terribly wrong. The mother of three was diagnosed with an aggressive head and neck cancer with just a 50% survival rate.

Two years later, she's cancer-free and looks like herself again. Her recovery represents a breakthrough in how doctors are fighting these diseases.

Penn State Health doctors can now test tumors at the molecular level to understand exactly what's driving each patient's cancer. A simple blood test reveals whether HPV caused the tumor, which completely changes the treatment approach.

"We can take a biopsy and see what's unique about it," says Dr. Neerav Goyal, head of Penn State Health's Head and Neck Oncology division. "That allows us to better tailor our treatment."

The same blood test works after treatment too. Doctors check whether cancer markers remain in the bloodstream, catching any lingering disease early.

For patients whose cancers respond to immunotherapy, this precision means doctors can reduce radiation intensity or avoid it altogether. That matters enormously in an area packed with vital organs.

Radiation therapy itself has transformed. Dr. Vinita Takiar's team delivers focused beams that hit tumors while sparing salivary glands and swallowing muscles nearby. Patients avoid the dry mouth and eating difficulties that plagued earlier treatments.

Surgery has leaped forward too. Robotic techniques give surgeons better visibility and precision, especially for early-stage cancers. Some patients need surgery alone, skipping radiation and chemotherapy entirely.

The Ripple Effect

Penn State's approach goes beyond individual treatments. A multidisciplinary team meets weekly to review every case together: surgeons, oncologists, pathologists, dentists, dietitians, and speech experts all contributing.

This collaboration means patients get comprehensive care plans that maximize survival while protecting quality of life. Clinical trials at Penn State are testing gene therapies to reduce dry mouth and drugs that lessen chemotherapy side effects.

The hospital's own provost, Fotis Sotiropoulos, credits a clinical trial with helping him beat neck cancer years ago. Now he watches that same commitment to research help hundreds of other patients.

HPV-related head and neck cancers are rising, but they respond better to treatment than cancers from other causes. Combined with these diagnostic and surgical advances, survival rates keep climbing.

Jackson's quick diagnosis started with a routine dental checkup. Dentists and primary care doctors now screen regularly for lumps, persistent sore throats, painful swallowing, and voice changes.

When Jackson needed surgery within a week of diagnosis, the Penn State team was ready with precision tools and personalized treatment that gave her family their wife and mother back.
