For more than three decades various forms of robotics have been effectively applied in healthcare to advance different types of medical treatment and surgical processes. Now, the nation’s first robotic positioning arm for proton therapy is being used by (LLUMC) to provide physicians improved access to tumors typically regarded as difficult to reach and treat.

An increasingly attractive alternative to standard photon beam radiation (or IMRT), a proton beam more effectively pinpoints cancerous tumors while minimizing contact with surrounding healthy bone and tissue. The robotic positioning arm at LLUMC’s takes that effectiveness one step further by giving physicians improved access to reach tumors such as those in the liver, breast, prostate and lung.

The user-friendly, computer-controlled robotic arm in use at Loma Linda is the most advanced proton technology found anywhere in the world and combines the flexibility and accuracy needed for optimal treatment of a tumor. The robotic arm decreases the time needed to position a patient for proton treatments and verifies the location and dose of the prescribed treatment based on the patient’s individualized treatment plan. By assuring such accuracy and controlling the movement of the patient during treatment, the hospital is better able to precisely and safely target the tumor in a way that provides the correct therapeutic dose and avoids harm to healthy tissues surrounding the tumor.

“In addition to successfully treating the cancer itself, a patient’s comfort during treatment is of the utmost importance to us,” said Jerry D. Slater, MD, chairman of the LLUMC center. “Not only does the robotic positioning arm allow proton beams to reach tumors more precisely, it’s also very comfortable for patients and helps alleviate some of the fears that traditionally accompany cancer treatment.”

Based on the expanded reach that the robotic positioning arm allows, physicians at LLUMC are now working on new clinical trials to study the effects of proton treatment on various types of tumors. According to Dr. Slater, “Since we have installed the robotic positioning arm, we have launched additional research studies such as our breast cancer trial to more closely examine the effects of treatment on tumors previously considered difficult to reach.”

Dr. Jerry Slater, along with his father Dr. James Slater, pioneered proton therapy at LLUMC more than 20 years ago, making it the world’s first hospital-based proton treatment center for cancer. It continues to be the leading hospital-based proton treatment center for cancer, bringing new innovations and technologies that serve patients from around the world.

Established in 1990, Loma Linda University Medical Center Proton Treatment and Research Center was the first hospital-based proton therapy center in the world. Today the center uses proton beam technology for many types of cancers and has treated more patients than any other proton treatment center worldwide. The center is part of LLUMC’s comprehensive health system, which is widely respected as a healthcare leader pioneering work in such areas as organ transplants, proton treatment for cancers, cardiac care, physical rehabilitation, acute pediatric and adult care as well as treatments for chemical dependence and other behavioral disorders. The health system – which includes Loma Linda University Medical Center and Children’s Hospital, LLUMC – East Campus, Behavioral Medicine Center, Heart and Surgical Hospital, LLUMC-Murrieta and physician clinics – collectively sees over 30,000 inpatients and about 750,000 outpatient visits a year.
