Anatomy

Epidemiology

Human papillomavirus

E6 suppress p53
E7 affects Rb
HPV vaccination

Natural History and Patterns of Spread

CIN1 – 60% regression
CIN2 – 40% regression

Progression typicallyl takes 10 to 20 years

  • Obturator lymph node
  • Venous plexus, paracervical veins โ†’ hematogenous dissemination

Clinical Presentation

Diagnostic Workup

Conization/Loop excision

If <2cm on PET and MRI, 
knife conization or lymphadenectomy for fertility preservation

Techniques Used for Treatment

Preinvasive Disease

Invasive disease

Surgical techniques

Simple conization

Radical trachelectomy

Selection criteria

  • age <40
  • stage IA1-IB1 with no nodal involvement on MRI and PET
  • SqCC or ADC with lesion <2cm
  • no LVSI on initial Bx
