The inferior pubic ramus is one of the two branches extending from the pubic bone, forming part of the pelvis. Inferior pubic ramus cancer refers to malignant tumors that originate in or spread to this bone. These cancers can be primary bone cancers (starting in the bone) or metastatic cancers (spreading from other body parts).
Pathophysiology
Structure
The inferior pubic ramus is a slender portion of the pubic bone, contributing to the pelvic ring’s stability. It provides attachment points for muscles and ligaments supporting the pelvic organs.
Blood Supply
Blood to the inferior pubic ramus comes mainly from the obturator artery and inferior epigastric artery, ensuring the bone receives necessary nutrients and oxygen.
Nerve Supply
Nerves supplying the inferior pubic ramus include branches from the sciatic nerve and genitofemoral nerve, which provide sensation and control muscle movements in the pelvic region.
Types of Inferior Pubic Ramus Cancer
- Osteosarcoma: A primary bone cancer common in young adults.
- Chondrosarcoma: Cancer of cartilage cells, typically in older adults.
- Ewing Sarcoma: A rare cancer affecting bones or soft tissues, mostly in children and adolescents.
- Metastatic Cancer: Cancers that have spread from other organs, such as breast, prostate, or lung cancer.
Causes
Inferior pubic ramus cancer can arise due to various factors, including:
- Genetic mutations
- Radiation exposure
- Previous bone diseases
- Paget’s disease of bone
- Family history of cancer
- Exposure to certain chemicals
- Chronic inflammation
- Age (more common in older adults)
- Gender (some types are more common in males or females)
