• To determine if combining Cetuximab with cisplatin
during radiation therapy increases overall survival (OS)
when compared with weekly cisplatin and radiation
therapy in patients with cervical cancer metastatic to
high common and/or para-aortic lymph nodes.
– Secondary Objective
• To determine if the addition of Cetuximab to cisplatin and radiation
therapy in this patient population improves progression-free survival
(PFS).
• To determine the relative toxicities of the addition of Cetuximab to
cisplatin in this patient population.
CVM0503
• Test the hypothesis that Cetuximab will
be more effective in tumors that express
low compared with high levels of the

AMENDMENT
• The Data Monitoring Committee (DMC) of the Gynecologic
Oncology Group convened to review the interim safety analysis
as outlined in section 11.5 of the study. In reviewing toxicity
data, there was a higher than 20% incidence of Grade 3 or 4
toxicity in the form of leucopenia and metabolic toxicity.
Median length of radiation therapy was similar in both arms
and there were no deaths related to study participation. Based
on their review in assessing the clinical impact of the toxicity,
the DMC recommended decreasing the starting dose on
regimen II to by one dose level rather than two dose levels as
originally stipulated in section 11.5. The starting dose on trial
(now dose level I) is the previous dose level -1 from former
versions (prior to NCI Version Date 10/03/2007).
GOG-0219
AMENDMENT
• Regimen II: Concurrent Cisplatin and TPZ and
Radiation Therapy (10/23/2007)
•
Cisplatin 60mg/m2 (max = 105 mg) administered IV
over 30-60 minutes days 1, 15 and 29 with radiation
therapy
• TPZ 220mg/m2 (max = 385 mg) IV administered
over two hours prior to Cisplatin on days 1, 15 and
29
• TPZ 220mg/m2 (max = 385 mg) IV over two hours
days 8, 10, 12, 22, 24, 26 with radiation therapy.
GOG-0219
AMENDMENT
• A second safety analysis will be performed
after treating 30 more patients on the TPZ
arm (with the new starting dose). In the
event Grade 3 or 4 toxicity continues to be
significantly higher among patients on the
TPZ arm or duration of radiotherapy is
prolonged significantly in any of the arms,
the trial committee may recommend further
dose modification or study termination.

Hypothesis
• To determine if adjuvant systemic chemotherapy
following chemoradiation therapy will improve
disease-free and overall survival compared to
chemoradiation therapy alone in patients with
high-risk early-stage cervical carcinoma found to
have positive nodes and/or positive margins
and/or positive parametria after a radical
hysterectomy. The expected benefit would be
approximately 10%-15% – Acrrual - 400 patients.

So where is my evidence?
Newer Approaches Induction
• Meta-analysis from data with Cis +/• Carboplatin vs Cisplatin
• Addition of Paclitaxel - Hoskin & GlynneJones
• Mexico- Duenas -Gonzalez
• UCL – McCormack CX2 study
• Still premature but exciting interest

Reed’s Observations
• I am convinced NACT is the way forward
• I am convinced dose dense and dose
intense schedules are needed
• I think a taxane is essential rather than
platinum alone
• I think TR and functional imaging
should be integral
So what would I propose??
• Fresh tissue for banking +/- serum
• Baseline scan , preferably PET CT +/- MRI (advice
from radiologists)
• Explore new imaging agents (hypoxia markers)
• 9 weekly doses of carbo/paclitaxel (AUC 2-3 and pac 6080 mg/m2)
• Reassess clinically and radiologically plus repeat samples
for freezing

• Tierney IPA suggests benefit
• Which maintenance?
• How many cycles
• Conventional or TAT or both

The Next Steps
• Next phase would be to consider

A pilot study of adjuvant

ANZGOG
Background
• Early-stage cervical cancer is highly curable
with surgical approaches or chemoXRT
• Lower cure rates with more advanced
disease seen in those who have not
participated in screening
• Traditional main prognostic factor is the
FIGO staging system - principally based on
clinical examination
• Uterine and nodal involvement on imaging
also prognostic
ANZGOG
Background
• Prospective audit data from 238 pts treated
with primary chemoXRT for cervical cancer
• 170 (71%) had corpus invasion on MRI
- 41% of these recurred cf. 19% without
invasion
• FIGO stage and clinical diameter not
prognostic in the presence of uterine
invasion
• 108 (45%) had PET +ve nodal disease
- 51% PET +ve recurred cf. 22% in PET -ve
• Majority of recurrences distant
ANZGOG
Narayan K 2006 and 2007
Background – adjuvant
chemo
• Chemo concurrent with XRT improves
survival and is standard care
• Additional chemo after chemoXRT may treat
distant mets and ↑ survival in high-risk pts
• Few small retrospective studies with older
chemo in unselected patients suggest no
survival advantage and some toxicity
• Carboplatin/paclitaxel active in cervical ca
and likely more deliverable after XRT than
cisplatin/topotecan
ANZGOG
Background – adjuvant
chemo
• GOG 109: post-op chemoXRT for those with
+ve nodes/ margins or parametrium involved
:2 extra cycles of cis/5FU given after chemoXRT
: subset analysis suggested improved PFS and OS
with more cycles of chemo
ANZGOG
Research Plan
Design: Single-arm phase II study
(n=30:pragmatic)
Eligibility: Stage 1b-IVa cervical cancer
suitable for primary treatment with
chemoradiation with curative intent in
addition to one of the high-risk features of:
a)Pelvic nodal involvement on:
- staging PET scan
- staging CT if >15mm diameter, or
- frozen section during planned surgery
leading to abandonment of planned
hysterectomy
ANZGOG
b) Uterine involvement on MRI
Aims and Objectives
• Aim: To test the feasibility of the regimen
• Primary objective: To determine the
percentage of patients able to complete all
treatment components without significant
treatment interruptions or omissions due to
grade 3 or 4 toxicity
• Secondary objectives: To determine the
- Acute and long-term toxicities
- Patterns of disease recurrence
- Failure-free survival
ANZGOG
Intervention
• 45-50.4 Gy of external beam XRT in 25 to
28 fractions plus brachytherapy
• Cisplatin 40mg/m2 weekly during XRT
• Within 4 weeks of completion of XRT and
following recovery from toxicities, 4 cycles
of 3 weekly adjuvant chemotherapy using
Carboplatin AUC 5 and Paclitaxel 175
mg/m2

GCIG Consensus: Cervical
Brachytherapy
• Produce a document that can be used as a
template for upcoming GCIG trials that
contains “acceptable” evidence based
brachytherapy dosing.
• Akila Viswanathan has agreed to head the
project.
• Plan to work via e-mail and possibly
conference call(s) with goal of finalizing the
manuscript by the cervical SOTS meeting in
2009.
