NCT05524389

Brief Summary

The purpose of this study is to compare the efficacy and toxicity of early stage endometrial cancer based on molecular classification and conventional risk stratification adjuvant therapy decision-making, and to provide high-quality evidence-based medical evidence for individualized adjuvant therapy selection under the guidance of fine stratification system of endometrial cancer.

Outcome Measures

Primary Outcomes (1)

  • Loco-regional recurrence (LRR)

    Loco-regional recurrence (LRR) is defined as the first recurrence in the vagina or pelvic cavity during follow-up, which was confirmed by imaging examination or biopsy pathology.

    3-year

Secondary Outcomes (9)

  • Failure free survival(FFS)

    3-year,5-year

  • Overall survical(OS)

    3-year,5-year

  • Cumulative vaginal recurrence

    3-year,5-year

  • Cumulative pelvic recurrence

    3-year,5-year

  • Distance metastasis(DM)

    3-year,5-year

  • +4 more secondary outcomes

Study Arms (2)

Molecular classification based treatment

EXPERIMENTAL

Establishment of molecular-clinicopathological classification to make adjuvant treatment decisions: observation for favourable group; vaginal brachytherapy(VBT) for intermediate group; external beam radiotherapy(EBRT) for unfavourable group. Molecular-clinicopathological classification strategy:Favourable group:POLE-mutated. CTNNB1(wide-type)with IA (G1-3) or IB(G1-2)and LVSI(lymph-vascular space invasion) focal/-. Intermediate group:MMRD and LVSI focal/-. CTNNB1(wide-type) and IB(G3) or II with LVSI focal/-. CTNNB1-mutated and IA(G1-3) or IB (G1-2) with LVSI focal/-. Unfavourable group: TP53 mutation. CTNNB1-mutated and IB (G3) or II. Substantial LVSI.

Conventional risk stratification based treatment

ACTIVE COMPARATOR

Adjuvant vaginal brachytherapy alone for intermediate risk patients (IA G1-2 with LVSI present or age\>60, IA G3 or IB G1-2 regardless of LVSI status). EBRT for high-intermediate risk (stage I B with G3, or stage II)

Radiation: Vaginal brachytherapyRadiation: Pelvic external beam radiotherapyDrug: Chemotherapy

Interventions

High-dose rate vaginal brachytherapy (VBT) was delivered with a vaginal cylinder.For VBT administered alone, the dose is recommended: 3 fractions of 7 Gy or 5 fractions of 6 Gy or 6 fractions of 5 Gy. For VBT administered after completion of EBRT: 2-3 fractions of 4-6 Gy.

Also known as: VBT
Conventional risk stratification based treatmentMolecular classification based treatment

EBRT was delivered to the pelvic area using a total dose of 45-50.4Gy in 25-28 fractions over 5-6 weeks with the intensity-modulated radiotherapy (IMRT) technique, three-dimensional conformal radiotherapy (3D-CRT) modality

Also known as: Pelvic EBRT
Conventional risk stratification based treatmentMolecular classification based treatment

No radiotherapy is administrated, but active follow-up and quality of life questionnaires is needed after surgery.

Molecular classification based treatment

Intravenous concurrent or sequential adjuvant chemotherapy consists of carboplatin/paclitaxel, cisplatin/doxorubicin or cisplatin/doxorubicin/paclitaxel, etc.
