Surgery May Raise Survival With Advanced Melanoma
By Robert Preidt
THURSDAY, Oct. 8, 2015 (HealthDay News) — New research suggests that for patients with melanoma that has spread to the abdomen, surgical removal of the tumor can extend survival.
The study was led by Dr. Gary Deutsch, now a surgical oncologist at North Shore-LIJ Health System in Great Neck, N.Y. His team tracked outcomes for 1,600 patients, treated at some point between 1969 and 2014.
According to the study, nearly one in four patients had surgery to remove the mass from their abdomen. Patients who underwent the surgery lived more than twice as long as those who received drug treatment alone — 18 months versus seven months, on average, the researchers reported.
The study was to be presented Thursday at the annual meeting of the American College of Surgeons (ACS) in Chicago.
According to the researchers, in the past, a melanoma that had spread to the liver or another organ in the abdomen was considered incurable. In those cases, surgery was typically deemed to be useless.
As well, in recent years powerful new immune-based drugs have given doctors new pharmaceutical options in fighting advanced melanomas, the researchers noted.
So, with all these changes, would surgical removal of part of a cancerous organ make any difference to patient survival? The new findings suggest that it might, Deutsch said.
“We have been trying to gauge the role of surgical resection for metastatic melanoma since the development of [immune-based drugs],” he said in an ACS news release.
“Today, metastatic melanoma is [also] discovered earlier in a number of patients,” Deutsch added, “likely because of better imaging techniques, so surgeons may be able to intervene before it becomes futile.”
In the new study, surgery was performed alone, or in combination with drug treatment or radiofrequency ablation, a technique that uses heat to destroy cancer cells.
All of the patients in the study had potentially operable melanoma that had spread to the abdomen. The sole site of abdominal cancer was the liver in nearly 700 patients, the gastrointestinal tract in 336, adrenal glands in 138, spleen in 109, and pancreas in 38. Another 305 patients had multiple cancer sites in the abdomen.
