“I was the person with the most recently diagnosed cancer at the conference,” said Kern, who completed his fellowship in urologic oncology at IU School of Medicine in 2021.
In April 2023, he was diagnosed with the very disease he specializes in curing. He returned to IU to be treated by his mentors.
“I’m probably the only urologic oncologist in the world who has testicular cancer,” said Kern, one of the military’s top experts in the field. “It was really weird to be on the other side of the conversation.”
Kern and several other medical professionals spoke at the 2023 Testicular Cancer Awareness Foundation (TCAF) conference, including IU Distinguished Professor Lawrence Einhorn, MD, who, in 1974, added an experimental drug to the chemotherapy regimen that quickly changed a testicular cancer diagnosis from a probable death sentence into a highly survivable disease, even at advanced stages.

“We not only need to cure patients, but we need to look at the burden of the cure, both during therapy and after completion of therapy,” Einhorn said at the conference.
Before his discovery of platinum-based chemotherapy, patients with metastatic testicular cancer had a mere 5% survival rate. Today, those patients have an 80% survival rate, and the overall testicular cancer survival rate is 95%.
Early on, Einhorn collaborated with John P. Donohue, MD, who developed a surgical procedure that brought testicular cancer patients from around the nation to Indianapolis for treatment. Later, the Einhorn-Donahue duo was joined by Richard Foster, MD, professor emeritus of urology, recognized as a world leader in the surgical management of testicular cancer.

“We have been providing surgical care for this disease for the past 60 years and have the world’s largest surgical experience in the complex management of advanced testicular cancer,” said Cary, who organized the conference at IU School of Medicine. “Our group pioneered many aspects of surgery including nerve-sparing techniques and surgical templates to minimize morbidity. In addition, our medical oncology colleagues, namely Lawrence Einhorn, helped revolutionize care with the introduction of platinum-based chemotherapy.
“Together, our collective group has revolutionized the cure rate of metastatic testicular cancer.”
A ‘surreal’ diagnosis
Because of IU’s reputation for successful outcomes, people come from all over the nation and world for testicular cancer care. No one expected Kern to be among them.
“It was a little surreal and hard to believe at first,” Cary said of the news that their former chief urology fellow was returning as a patient.
A year prior to his diagnosis, Kern founded the Testicular cancer Enterprise for Survivorship, Treatment, and Investigational Sciences (TESTIS) at the Murtha Cancer Center at the Uniformed Services University and Walter Reed National Military Medical Center. TESTIS includes a patient database for outcomes follow-up, mental health and fertility counseling, and investigative research aimed at minimizing the negative side effects of cancer treatments.
“Everything IU is doing in testicular cancer, we are building for the military,” Kern said.

“I was really surprised when I felt a mass,” he said, recalling the moment he discovered a lump while performing a routine self-exam on Easter evening. “I knew right away—I knew it was almost a guarantee it was cancer.”
After surgery and tests confirming the diagnosis, Kern was on a plane to Indianapolis. Einhorn, his revered mentor, was now his cancer doctor.
There was no question Kern wanted to be treated at IU.
“These are the experts,” he said. “Not only are they good at treatment, but they’re also good at managing the side effects.”
At IU Health, Kern discovered additional resources to support his recovery. As a surgeon, he was especially concerned about peripheral neuropathy, a side effect often associated with chemotherapy, that could cause numbness in his fingers. He welcomed oncology massage, offered by massage therapist Michelle Bailey, and took advantage of an exercise therapy program developed by Tarah Ballinger, MD, offered free to patients at the cancer center.

“My current anxiety is fear of recurrence—they call it scan anxiety,” Kern said.
He and his wife, Aneta, a clinical psychologist, both spoke at the conference as experts and inspirational speakers, relating to survivors and caregivers in a way that only comes from lived experience.
“Sean’s story showcases the power of having a support system in place, but also the need to surrender to the process after diagnosis, knowing that living through this isn’t the same as treating the disease,” said TCAF Founder and CEO Kim Jones, whose own caregiver journey with son, Jordan, was the impetus for the foundation.

Kern is now a board member for the foundation, using his unique perspective to help guide TCAF’s support programs. He is grateful to his mentors at IU for not only their expertise but their compassionate care during his own treatment journey.
At the conference, Jones presented Einhorn with a plaque recognizing IU Simon Cancer Center as a TCAF Testicular Cancer Center of Excellence.
