HealthNews I he modern pathologist's jobs are far more complex than just determining if body tissues are normal or abnormal. If the tissue is positive for cancer cells, other questions need answering: How aggressive is it? Has it spread from somewhere else? From what organ did it originate? The answers to these questions ultimately guide the patient's doc- tor in choosing the best treatment plan. Medical science has produced a technical crystal ball to help the modern laboratory answer these questions. "We use image analysis, a very powerful technique," says Gilbert E. Herman, Ph.D., M.D., Acting Chairman of Sinai's Department of Laboratory Medicine. Sinai pathologists can assess the DNA (genetic cellular information) con- centration in tumors using a space- age technique called DNA ploidy. "We are also nationally known for our expertise in immunohisto- chemistry," Dr. Herman reports. This particular laboratory test can identify the original site of some tumors which have metastasized (spread to other areas of the body). V• ■ SINAI HOSPITAL Dr. Gilbert Herman, Acting Chairman of Sinai's Department of Laboratory Medicine, consults with Dr. Eduardo Phillips, Chairman of the Department of Surgery, about the original site of a tumor. "Yesterday, for example, we used immunohistochem- istry on a tumor that was removed from a lung. We proved the tumor was from the prostate." This avoided a CAT scan and MRI stud- ies which would normally be required during a search for tumor origin. Besides being extremely cost-effective, immunohis- tochemistry saves the patient from a lot of un- necessary tests that can be very time-consuming and stressful. Sinai maintains a team of board-certified anatom- ic and clinical pathologists, each of whom specialize in a particular organ system, such as reproductive or digestive. "What sets us apart," Dr. Herman says, "is the quality and the stability of the pathology group along with our conscien- tiousness and our rapport with the staff doctors. "We are not confined to the lab- oratory at Sinai. Pathologists are in the operating rooms to help the surgeon determine where the tumor begins and ends, if it is ma- lignant or benign, and the proba- ble point of origin." Dr. Herman and his colleagues are constantly teaching and learn- ing. By checking diagnoses against the final surgical data, pathologists keep their skills finely tuned. The correct diagnosis dictates the en- tire treatment of the patient. New Alternative for Cancer Therapy Available at Sinai Elayne Arterbery, M.D., came to Sinai from the fulltime fac- ulty at Johns Hopkins Oncol- ogy Center. She completed her medical training at the University of Michigan and did a radiation oncology residency at Memorial Sloan-Kettering Cancer Center in New York City. Dr. Arter- berry was attracted to Sinai specifical- ly because Sinai is performing the ultimate state-of-the-art radiation treatment with very high-tech equip- ment. "Sinai's approach and technolo- gy are comparable to the major cancer centers such as Memorial Sloan- Kettering, M. D. Anderson, and the University of Michigan, but in a com- munity rather than an academic setting." Like some of these major cancer cen- ters, Sinai is using low-dose radiation SPRING 1995 ISSUE implants to treat prostate and sever- al other types of tumors. New technol- ogy allows doctors to place tiny radioactive seeds (smaller than grains of rice) into a tumor without need for surgery. The amount of radiation in each seed is very low , so it presents little threat to the normal tissue and organs surrounding the tumor. But, because it is located right at the sight of the tumor cells, it is deadly to those cells. Precision is the key word in this type of therapy. Ultrasound, CAT scans, and MRI tests can measure tumor size and location with amazing accuracy. Corn- puter analysis determines exactly where to place all of the seeds through- out the tumor so that there are slight overlaps in the effective range of each seed. Ultrasound is used during the implantation procedure to guide the physician to the exact placement posi- tions. This way there will not be any areas of the tumor which go unaffect- ed by the radiation. Some advantages of low-level radi- ation implants are the lowered risk of damage to healthy tissues, the procedure does not require surgery, and more radiation can be delivered in concentrated form when compared to external radiation therapy. This procedure is especially well suited to older patients who are not good can- didates for surgery and would not fare well from extensive exposure to radiation. Medical science is making significant advances in treating cancer. That tech- nology is available at Sinai. The teaching occurs in many fields. Dr. Herman has taught in- ternational classes on immuno- histochernistry. Many members of the department have published re- search and teach at Wayne State University's School of Medicine. Dr. Herman has lectured at the Na- tional Institutes of Health and the Food and Drug Administration. Dr. Herman is proud that Sinai's Department of Laboratory Medi- cine has a national reputation for expertise in high-tech automation in pathology. But, he hastens to note, that's not the only reason it is an excellent department. `The strength of the pathologist's knowledge is vital to the quality of the department. It's the education, training, continuing education, ac- tive participation in case manage- ment (including tumor boards or other clinical forums), teaching, and research activities which ex- pand that knowledge." Add to all of that the specialty expertise and new high-tech equip- ment, and you have a superior De- partment of Laboratory Medicine. It is all available at Sinai.
