The Slimmest Margin

After a routine blood test showed low iron levels, 77-year-old Rick underwent an endoscopy that revealed a four-centimeter malignant esophageal mass. The tumor’s size put him at risk of an esophagectomy, a high-risk surgery that would remove all or part of Rick’s esophagus. Hoag’s specialized gastroenterologists and oncologists acted quickly to help him avoid invasive cancer therapies and irreversible surgery.

Science-Backed Precision

Rick went to Dr. Kenneth Chang, a renowned expert in endoscopic oncology and the Executive Medical Director of Hoag’s Digestive Health Institute, for a life-changing procedure. Imaging revealed the cancer was microns from the muscle layer—a narrow margin that made endoscopic removal possible but extremely risky. Determined to spare Rick’s esophagus, Dr. Chang immediately performed an advanced Endoscopic Submucosal Dissection (ESD). Over three tense hours, he navigated the delicate procedure, where even the slightest misstep could lead to serious complications.

Life-Changing Procedure

The operation was successful. The following week, Hoag’s Tumor Board would confirm the results: this was a curative resection. The cancer was completely removed. Without any need for chemotherapy, radiation or organ-removing surgery, Rick found himself back where he had been the day of his diagnosis just two weeks earlier; on the golf course. In that same day he received the good news from Dr. Chang, he competed in a tournament and won.

Miraculous Outcome

Dr. Chang is one of few physicians nationwide with the required training, skillset and procedural volume to perform this advanced and highly specialized endoscopic technique. “In my nearly 40 years as an endoscopist, these were some of the slimmest margins I’ve ever worked with,” remarked Dr. Chang. “And the outcome was truly miraculous.”

Rick’s experience is unique and may not be representative of all patients. The type, stage, and treatment of cancer can significantly impact outcomes. Always consult with a healthcare professional for medical advice tailored to your individual circumstances. Results may vary.
