Robert Harley confesses to fighting “rare cancer with only 0.1%”… what kind of cancer is it?

Robert Halley, who has been self-isolating on drug charges, has confessed to being battling a rare cancer. Robert Halley, who appeared on MBN’s ‘Field Report Scoop World’ on the 19th, said that he was diagnosed with ‘malignant peripheral nerve sheath tumor (MPNST)’ and has been fighting the disease.

Robert Halley said, “My whole body is swollen. His stomach doubled, and his legs doubled. He is one of the rarest cancers in the world.” He had symptoms of inflammation in his leg that did not subside two years ago, after which a malignant tumor was discovered and he was diagnosed with cancer. He is said to be currently focusing on his rehabilitation after undergoing resection.

Malignant peripheral nerve sheath tumor (MPNST), which Robert Halley said was suffering, is a type of cancer that develops in nerves. According to the National Institutes of Health (NIH), malignant peripheral nerve sheath tumor is a type of sarcoma that grows in soft tissues of the body, such as muscles, fat, tendons, ligaments, lymph and blood vessels, and nerves. Here, sarcoma refers to cancer that occurs in non-epithelial connective tissues such as bone, muscle, and fat. It is known that the incidence is rare compared to carcinomas such as colorectal cancer and breast cancer.

Malignant peripheral nerve sheath tumors are rare among sarcomas, accounting for about 5% to 10% of sarcoma cases. Although the exact cause is not known, it is known to be more common in people with the genetic disorder neurofibromatosis type I. Neurofibromatosis type I is a disease caused by mutations in the NF1 gene and is known to occur in about 1 in 3,500 to 4,000 people. According to the NIH, about 25-50% of patients with malignant peripheral nerve sheath tumors are neurofibromatosis type I.

A typical symptom of malignant peripheral nerve sheath tumor is swelling of the arms and legs. According to the Korean Society of Orthopedic Surgery, “edema may occur in the limbs, and there is usually no pain. “Sometimes I feel limp when walking or have difficulty moving my limbs,” he explains.

The 5-year survival rate of malignant peripheral nerve sheath tumors varies depending on the size and location of the tumor, but is approximately 23-69%. This is lower than the 5-year survival rate of cancer patients of 70.7% (based on the 2019 National Cancer Registry Statistics). As with all cancers, to improve survival, early diagnosis and treatment must be made before it spreads to other parts of the body. For the diagnosis of malignant peripheral nerve sheath tumor, tests such as MRI and whole-body bone scan are required. After diagnosis, surgery, radiation therapy, and chemotherapy are performed.
