Study summary

This study investiagates deep-regional or superficial hyperthermia to enhance radiotherapy or chemoradiation in patients that suffer recurrent disease after previous radiotherapy.

Read the detailed description

patients that present a relapse within the previously irradiated volume can be included in this trial. These patients will receive re-irradiation according to clinical guidelines and hyperthermia as study intervention. According to tumor location hyperthermia can either be performed by microwave or by capacitive devices.

The primary endpoint of this study is non-inferiority of re-irradiation compared to the initial course of radiotherapy (calculated as time to local failure).

Inclusion criteria

  • prior radiotherapy of the treatment side with a treatment dose > 30 Gray (Gy) EQD2 (calculated with alpha/beta value of 9)
  • local/ regional / or oligometastatic tumor recurrence. Maximum number of three macroscopic tumor lesions with at least one of them receiving prior radiotherapy
  • macroscopic tumor recurrence
  • side of recurrence is amenable to hyperthermia (abdomen, pelvis, extremities, spine, cervical lymphnodes)
  • planned re-irradiation dose of at least 40 Gy EQD2 (calculated with alpha/beta value of 9)

Exclusion criteria

Exclusion Criteria:

  • >3 macroscopic tumor lesion
  • brain metastases
  • recurrence is amenable to local ablative radiotherapy (brachytherapy or stereotactic radiotherapy)
  • recurrence region is not amenable to hyperthermia (lung, liver, mediastinum)
  • contraindications for hyperthermia (serious cariovascular disease, ICD or larger implants at the treatment site)
  • psychiatric disorders that impede proper informed consent
  • serious comorbidities with very limited prognosis quo ad vitam

Study arms

  • Experimental
    Hyperthermia

    Patients will receive 6-8 treatments additional loco-regional hyperthermia concurrent to re-irradiation. Hyperthermia will start on the third day of fractionated radiotherapy and will be given twice per week. According to site of recurrent disease either deep-regional, capacitive or superficial hyperthermia devices may be used.

    Device: loco-regional hyperthermia

Interventions

  • Deviceloco-regional hyperthermia

    loco-regional hyperthermia by the use of microwave, capacitive, or superficial hyperthermia devices.

What researchers measure

Primary outcomes

  1. Local tumor recurrence

    Local tumor recurrence of re-irradiated lesions, calculated with the Kaplan-Meier estimates. Local recurrence after hyperthermic re-irradiation will be compared to time-to recurrence after initial treatment.

    Time frame: 3 years

Secondary outcomes

  1. Overall survival

    Overall survival after start of re-irradiation

    Time frame: 3 years

  2. Progression-free survival

    Progression-free survival after start of re-irradiation

    Time frame: 3 years

  3. Freedom from distant metastases

    Freedom from distant metastases after start of re-irradiation

    Time frame: 3 years

  4. Patient reported quality of Life

    patient reported quality of life measured by the EORTC qlq-c30 questionnaire.

    Time frame: 3 years

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Start is estimated for May 2024; primary completion for Jan 2026, 20 months later.

Of 409 non-industry phase 2 interventional studies under Recurrence, half reached primary completion within 52 months of starting (the median), counting those still running; a quarter within 35 and three quarters within 85. This study's planned 20 months is below that.

Counting every sponsor, half of 499 studies reached it within 49 months; a quarter within 31 and three quarters within 78.

Recurrence covers many different conditions, not one, so the studies compared here vary widely. Read these figures as a rough guide.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Dec 26, 2023, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
