Quizplus · Accepted Answer

The presence of distant metastasis, such as bone metastasis to the right femur, in a patient with neuroblastoma indicates a diagnosis of Stage 4 disease according to the International Neuroblastoma Staging System (INSS). Stage 4 is characterized by the spread of the tumor to distant lymph nodes, bone, bone marrow, liver, skin, and/or other organs (excluding Stage 4S criteria).
