than nuns

Radical hysterectomy
• Used to treat cervical
cancers with invasion
> 3mm but confined
to the cervix and
vagina < 4 cm (Stage
IA2 –IB1)
• Removal of
parametrium and
upper vagina

Acceptable Alternatives to Radical
Abdominal Hysterectomy and
Lymphadenectomy for
Stage IA2 and IB1 Cervical Cancer
• Radical traechelectomy (or cone) and nodes
(Fertility sparing)
• Intracavitary brachytherapy and pelvic RT +/- chemo
• Laparoscopic radical hysterectomy and nodes
• Robotic radical hysterectomy and nodes
• Simple hysterectomy and nodes
[email protected]
When is RT or Chemo/RT Indicated
After Radical Hysterectomy?
Radiation if two of the following:
• deep invasion, large tumor or vascular invasion
– GOG 92 (Sedlis A et. al Gyn Onc 73:177-183, 1999)
Chemo-RT if one of the following:
• Positive margin, parametrial extension, positive node
– GOG 109 (Peters WA et. al. J Clinic Oncol 18:1606-1613, 2000)
RT=Radiation therapy
[email protected]
Early Stage Intermediate Risk Cervical Cancer
• Large, deeply invasive tumors with vascular invasion
limited to the cervix after radical hysterectomy
• GOG 92 established to role of postoperative pelvic
radiation (Sedlis et al Gyn Oncol 73, 177–183 1999)

What is the Global Standard
Therapy for Stage IB2 - IVA?
• External beam pelvic radiation (40 to 60 Gy)
• Brachytherapy (8,000 to 8,500 cGy to Point A)
• I.V. Cisplatin chemotherapy
– Cisplatin 40mg/m2 (Max dose 70mg) IV q wk
during RT (6wks)

Chemotherapy for Recurrent Cervical Cancer Lessons Learned in the 80’s and 90’s
• Platinum-based therapies most effective
• Cisplatin more active than carboplatin
• Two ways to increase response without prolongation in
Survival
– Increase platinum dose
– Add Ifosfomide to cisplatin
• Single agent cisplatin at 50 mg/m2 became standard
