• Type I (Extrafascial hysterectomy): simple hysterectomy to remove theentire cervical tissue
• Type II (Modified RH): basically, the RH described by Wertheim, toremove more paracervical tissue while still preserving the blood supplyto the distal ureters and bladder
• Type III (RH): first described by Meigs in 1944, with the purpose of awide excision of parametrial and paravaginal tissue
• Type IV (Extended RH): complete removal of the periureteral tissueand a more extensive resection of the paravaginal tissue
• Type V (Partial exenteration): radical removal of disease involving thedistal ureter and/or bladder

Radical Hysterectomy – Querleu-Morrow Classification
• Type A (Minimum resection of paracervix): extrafascial hysterectomy,corresponds to the type I RH, with a <10 mm vaginal resection
• Type B (Transection of paracervix at the ureter): corresponds to thetype II RH, with (B2) or without (B1) additional removal of the lateralparacervical lymph nodes, and >10mm vaginal resection
• Type C (Transection of paracervix at junction with internal iliac vascularsystem): corresponds to type III RH, with the ureter completely mobilized,15-20mm of vagina and corresponding paracolpos resected routinely;with (C1) or without (C2) autonomic nerve preservation
• Type D (Laterally extended resection): ultraradical procedures mostlyindicated at the time of pelvic exenteration, with the entire paracervicalresection at the pelvic sidewall including the hypogastric vessels (D1);type D2 includes the resection of adjacent fascial-muscular structures
Querleu, 2008

It is recommended to include the following information in the operativereport:
• All parts defining the type of RH (transection of paracervix andvagina, uterine artery)
• Surgical (fresh sample) and pathological (fixed sample) length ofventral, dorsal and lateral extent of paracervix resection
• Surgical/pathological minimum length of vagina resected
• Minimum distance between tumor and resection margins (whenapplicable)
Quality control and results comparison in RH
The term paracervix replaces others such as cardinal or Mackenrodt’s ligament, or parametrium, and includes that usually named as paracolpium

Review & Meta-analysis
The absolute improvement in survival of 15% (8-21%) at 5-years obtained by NACT is of the same magnitude as thatachieved with the standard cisplatin-based CTRT
