Trial summary

RATIONALE: Drugs used in chemotherapy, such as cisplatin, paclitaxel, and carboplatin, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Radiation therapy uses high-energy x-rays to kill tumor cells. Read more about this study

About this study

Official title: Randomized Phase III Trial Comparing Concurrent Chemoradiation and Adjuvant Chemotherapy With Pelvic Radiation Alone in High Risk and Advanced Stage Endometrial Carcinoma: PORTEC-3

RATIONALE: Drugs used in chemotherapy, such as cisplatin, paclitaxel, and carboplatin, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Radiation therapy uses high-energy x-rays to kill tumor cells. Giving chemotherapy and radiation therapy after surgery may kill any tumor cells that remain after surgery. It is not yet known whether giving chemotherapy together with radiation therapy is more effective than giving radiation therapy alone in treating endometrial cancer.

PURPOSE: This randomized phase III trial is studying chemotherapy and radiation therapy to see how well they work compared with radiation therapy alone in treating patients with high-risk, stage I, stage II, or stage III endometrial cancer.

Read the detailed description

OBJECTIVES:

Primary

  • Compare the overall survival and failure-free survival of patients with high-risk stage IB-III endometrial carcinoma treated with concurrent chemoradiotherapy followed by adjuvant chemotherapy vs pelvic radiotherapy alone.

Secondary

  • Compare the rates of pelvic and distant recurrence, severe (grades 3 and 4) treatment-related toxicity, and quality of life of patients treated with these regimens.

OUTLINE:

This is a multicenter, prospective, open-label, randomized, controlled study. Patients are stratified according to participating group (DGOG vs UK NCRI vs NCIC CTG vs MaNGO vs Unicancer), type of surgery (total abdominal hysterectomy and bilateral salpingo-oophorectomy [TAH-BSO] vs TAH-BSO plus lymphadenectomy vs laparoscopic hysterectomy [TLH-BSO] vs TLH-BSO plus lymphadenectomy), stage (IA vs IB vs II vs III), and histological type (endometrioid carcinoma vs serous or clear cell carcinoma). Patients are randomized to 1 of 2 treatment arms.

  • Arm I: Patients receive external-beam pelvic radiotherapy 5 days a week for up to 6 weeks, combined with cisplatin IV days 1 and 22. Patients with cervical involvement undergo vaginal brachytherapy boost. At least 3 weeks after completion of chemoradiotherapy, patients undergo adjuvant chemotherapy comprising paclitaxel IV and carboplatin IV on day 1. Adjuvant chemotherapy repeats every 3 weeks for up to 4 courses in the absence of disease progression or unacceptable toxicity.
  • Arm II: Patients undergo external-beam pelvic radiotherapy (and vaginal brachytherapy alone in case of cervical involvement) as in arm I.

Quality of life is assessed at baseline, completion of radiotherapy, completion of chemotherapy, at 6 months, and then once a year for 5 years.

After completion of study therapy, patients are followed periodically for up to 10 years.

PROJECTED ACCRUAL: A total of 670 patients will be accrued for this study.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Radiation Therapy, cisplatin and carboplatin in people with Endometrial Cancer, run by Leiden University at 1 site in Netherlands.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 12 inclusion and 11 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 11 Oct 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Netherlands. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Overall survival (time frame: 5 years). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00411138, which also lists 12 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 11 Oct 2023.
