BACKGROUND Poliomyelitis is an acute infection caused by an enterovirus,which primarily infects the human gastrointestinal tract.In general,patients with polio have no association with the occurrence of cancer.The present case study presents a rare case of poliomyelitis combined with primary breast cancer.CASE SUMMARY A 61-year-old woman who was diagnosed with poliomyelitis at 5 years old and confirmed invasive breast cancer by core needle biopsy(CNB)after hospitalization.The patient received a modified radical mastectomy and four cycles of chemotherapy with the TC(docetaxel and cyclophosphamide)regimen.The patient was also prescribed endocrine therapy without radiotherapy after chemotherapy.The patient had no evidence of lymphedema in the right upper extremities and no evidence of either regression or distant metastasis at the 1-year follow-up.CONCLUSION The pectoral muscles of patients with polio are easily damaged in traumatic procedures,such as CNB,local anesthesia for tumor excision,and general anesthesia for surgery.A CNB,modified radical mastectomy,and four cycles of TC chemotherapy were successfully completed for the present case and the adverse reactions were found to be tolerable.This case may indicate the relationship between breast cancer and polio,and the examination and treatment methods used could be used as a guide for similar cases in the future.
