Relapsed Cervix Cancer • Follow up of Cervix Cancer • Careful Monitoring • Clinical exam • Symptoms • Is there any role for routine imaging? • Imaging, CT MRI (PET) • Role of Pap smears
Problems of Diagnosing Relapse • Post Radiation Effects • Difficulty in Interpretation • Need for Histological confirmation • Wait 3 months after treatment
Prediction of Relapse • Traditional data indicate about 35% of patients will relapse • Stage 1B ) 10-20% • Stage 2A ) • Stage 3B ) • Stage 4A ) 60-70% • Stage 4B )
Typical Symptoms of Relapse • Weight loss, Leg Oedema • Pelvic and/or thigh/buttock pain • Back ache • Bloody vaginal discharge • Supraclavicular Lymph Nodes • Cough, SOB, Haemoptysis • Chest pain
Sites of metastatic disease Metastatic sites treated patients Henriksen E: Am J Obst &Gyn 1949 Metastatic sites untreated patients Henriksen E: Am J Obst & Gyn 1949
Relapsed Cervix Cancer Following RT • 27% relapses in Cervix / Uterus or upper vagina • 6% Lower vagina • 43% Parametrium • 16% Distant • 8% Unknown Following RHND • 25% local recurrences at vault/upper vagina
Relapsed Cervix Cancer • Triad of: • Weight Loss + Pelvic Pain + Oedema Legs • Ureteric obstruction • Back ache from Hydronephrosis
Relapsed Cervix Cancer • Traditionally most deaths within 1st year • 50% of deaths within 12 months • 25% in second year • 15% during third year • Newer CCRT may delay this pattern
Chemotherapy for Relapse • Predictors of Response • Site of disease following RT • Intra Field vs Outwith RT field • e.g. Para-aortics • Chest, Lung mets only • Other sites
Localised Disease Surgery (Exenteration) Radiation Chemo-radiation Metastatic disease Chemotherapy Hyperthermia Chemo-radiation New Drugs Novel approaches Management of Relapse
Response Rates • Response with Isolated Relapses • Response in lungs : CR 53% OR 73% • Response in pelvis : CR 0% OR 21% (Potter M : Cancer 1989) • Highlights Issues of vascular access • Hypoxia • Most studies differentiate prior RT
Chemotherapy for Relapsed disease • Wasserman & Carter 1977 Review • Limited drugs available • No differences allowed for site or prior therapy • Pre Platinum era
Chemotherapy for Cervix • Post 1977 • Recognition of influencing factors • Chemo naïve vs prior therapy • Previous EBRT • Advent of cisplatin • Major Impact!!
Platinum • Initial data used cisplatin @ 50 mg/m2 • Given every 3 weeks • GOG 43 : 20-31% RR
Ifosfamide Phase 2 studies • Coleman R 16-40% RR incl. 20% CR and median response of 26 mo • Sutton GOG : 15.7% RR • Cervellino 1995 : 50 RR% • Cis vs Cis Ifos GOG

Future Directions Outside clinical trials the use of Cisplatin alone is still the gold standard if chemotherapy is used for palliation. The use of more aggressive regimes seems to bring additional toxicity. GOG 169 and 179 bring fresh light.
