PHASE III TRIAL OF PELVIC RADIATION THERAPY VERSUS VAGINAL CUFF BRACHYTHERAPY FOLLOWED BY PACLITAXEL/CARBOPLATIN

CHEMOTHERAPY IN PATIENTS WITH HIGH RISK, EARLY STAGE ENDOMETRIAL CANCER

Regimen I: •Pelvic Radiation Therapy (4500/25 fractions-5040 cGy/28 fractions) over 5-6 weeks•Optional Vaginal Cuff Boost ONLY for Stage II patients and Stage I patients with papillary serous and clear cell carcinomas

GOG 0249

RANDOMIZE

Eligible:

•Stage I-IIA endometrial carcinoma, with high-intermediate risk factors•Stage IIB (occult) endometrial carcinoma (any histology), with or without risk factors•Stage I-IIB (occult) serous or clear cell endometrial carcinoma, with or without other risk features

Regimen II: •Vaginal Cuff Brachytherapy + 3 cycles of chemotherapy* consisting of: •Paclitaxel 175 mg/m2 (3hr) + Carboplatin AUC 6 q 21 days

*To start within 3 weeks of initiating brachytherapy

GOG0261

• Stage I-IV, Persistent or Recurrent Carcinosarcoma (chemotherapy- naïve)• Patients may have prior pelvic and/or vaginal radiation therapy

Stratification:• History of Pelvic Radiation• Disease Status/ Stage at time of Study registration• Measurable Disease

*Initial dose reduced to Paclitaxel 135 mg/m² and Carboplatin (AUC=5) if prior whole pelvic radiotherapy** Initial dose reduced to Ifosfamide 1.2 g/m²/day x day days if prior whole pelvic radiotherapy*** See Sec. 5.22 for Mesna administration information.

RANDOMIZE

Quality of Life assessments required at: Baseline; approximately week 6 (prior to cycle 3); week 15 (prior to cycle 6); week 26 post initiation of therapy. See section 7.3 for details.

Translational Research requirements include an archival formalin-fixed and paraffin-embedded tumor specimen and a pre-treatment whole blood specimen as described in Section 7.2

REGIMEN I:Paclitaxel 175 mg/m²* IV over 3 hours day 1Carboplatin (AUC=6*) IV day 1Repeat q 3 weeks x6 cycles

G-CSF Support:Filgrastim or Pegfilgrastim beginning day 4-6 (see Section 5.22.)

Concept

Biweekly dactinomycin now needs to be tested against 8-day MTX/FAR, arguably the most commonly used regimen worldwide. The 8-day regimen has a similar primary response but a vastly different cost, resource and utility profile, and it has never been subjected to the scrutiny of a multi-centred RCT.
