1.      Background

Malignant gliomas, such as glioblastoma multiforme, are the most common type of primary brain tumours of the central nervous system and remain incurable. The efficacy of surgical resection, radiotherapy and chemotherapy seems to have reached a plateau. In spite of the benefit of postoperative radiotherapy, the mean survival is less than 12 months.

One of the major factors of the poor response to therapy is the tumour cell heterogeneity containing oxygen deprived tumour areas (Vaupel 1991, Denekamp 1996). It has been long recognised that oxygenation influences the response of tumours to radiation and may led to radioresistance. For sterilisation of hypoxic tumour cells, a three times higher radiation dose is required than for cells at normal oxygen tension. Recently, Collingridge et al. (1999) quantified the spatial distribution of the oxygen pressure (pO2) in glioma by polarographic measurements. The study showed regions with oxygen tension less than 2.5 mm Hg. Hence, hyperbaric oxygenation (HBO) is a promising approach to cope with the phenomenon of hypoxia and to increase the cellular radiation sensitivity (Nordmarks 1996, Overgaard 1996).

The theoretical basis for the use of HBO as an adjunct to radiotherapy is as follows:

 

·        Hypoxic regions are present in malignant gliomas.

·        Non-proliferating, quiescent hypoxic cells are radioresistant compared to their well-oxygenated counterparts. Following irradiation, well-oxygenated cells will be lethally damaged. As a result, hypoxic cells will be reoxygenated, enter the proliferative tumour cell compartment and repopulate the tumour.

·        The larger the number of cells that lose their reproductive capacity, the greater the probability of palliation.

 

Several experimental studies indicated that the radiation response can be enhanced under HBO (Johnson 1978, Brizel 1997, Hartmann 1997). Hyperbaric oxygen exposure was used in combination with radiotherapy to treat malignant gliomas (Kohshi 1999). Fifteen patients (10 glioblastoma, 5 anaplastic astrocytoma) were irradiated within 15 minutes after HBO. The median survivals in patients with and without HBO were 24 and 12 months, respectively, and were significant different. No serious side effects were observed in HBO patients. However, a major drawback of this promising non-randomised study presents the concurrence of patients with two pognostically different tumours.

 

 

2. Objectives

 

Main endpoint:

·        Efficiency on median survival of HBO prior to conventional radiation

 

Secondary endpoints:

·        Efficiency on recurrent free survival of HBO before conventional radiation

·        PET study to assess metabolic changes before and after therapy (optional)

·        Influence on quality of life

 

 

3.      Study population

 

Inclusion criteria:

·        Pathologically verified glioblastoma multiforme

·        Complete or partial macroscopic surgical resection, or biopsy only

·        Karnofsky status ³ 70%

·        Leucocytes ³ 3000

·        Thrombocytes ³ 100.000

·        Hemoglobin ³ 10 g/dl

·        HBO fitness

·        Informed consent

 

Exclusion criteria before therapy:

·        Age < 18 years

·        Karnofsky status < 70%

·        Prior chemotherapy

·        Prior brain irradiation

·        Pregnancy

·        Secondary malignancies, except squamous cell carcinoma of the skin.

·        Severe internal or neurological disease

·        Contraindications to HBO: as assessed by the medical direction of the HBO facility.

 

Breaking off criteria / exclusion criteria during therapy:

·        Severe side effects (WHO III-IV)

·        Lacking concordance

In these cases, patients will be treated following the conventional radiotherapy protocol.

 

 

4.      Sample size assumptions and estimates

 

Phase III trial: - prospective, randomised, unblinded

·        Sample size: 40 patients each group

 

 

5.      Enrolment of participants

 

5.a. Baseline examinations

 

Clinical examination:

General clinical examination, including neurological status and Karnofsky performance status. CTC status (common toxicity criteria).

 

HBO fitness examination:

According to the regulations of the medical director.

 

Laboratory investigations:

Blood cell count, Hematocrit, Na, K, Cl, Creatinin.

 

Preclinical examination:

Contrast-enhanced computerised tomography (CT) or magnetic resonance imaging (MRI) scan. Optional: PET scan (FDG uptake).

These methods are used to evaluate the tumour volume before and after treatment.

 

 

5.b.Personal data:

Age, date of diagnosis, tumour localisation, operation status (complete macroscopical resection, partial resection, or biopsy only).

 

Subjective evaluation: Quality of life questionnaire.

 

 

6.      Randomisation (Phase III)

 

After informed consent, patients will be randomised into two arms (A: with or B: without HBO; the irradiation treatment is identical in both groups) using a blinded envelope technique, consisting of a choice of 1 to 10 envelopes (5 containing a piece of paper indicating `HBO`). Every patient will be presented 10 envelopes, in order to give every patient a 50% probability of HBO.

 

 

7.      Intervention

 

Radiotherapy must begin within three weeks after surgery.

 

Procedure: Three-dimensional treatment planning aiming for application of 60 Gy tumour dose in daily fractions of max. 2 Gy. Overall treatment time: 6-7 weeks.

 

Arm A patients will receive HBO before irradiation. At least 80% of the irradiation fractions should be preceded by HBO.

 

·        each irradiation must be given within 20 min. of HBO treatment.

·        all irradiation fractions should be preceded by HBO treatment at 2.5 (2.4-2.6) (to be specified exactly) ATA for 60 min. without air breaks.

 

Transcutaneous oxygen measurements will be done to confirm hyperoxygenation.

 

Patients should be transported from the HBO facility to the X-ray machine without excersion. The time interval between HBO treatment and radiotherapy must be recorded.

Arm B patients will not be submitted to (sham) compression.

 

 

8.      Blinding

 

Presence of complications and side effects will independently be recorded be a clinician treating the patient, and analysed by a researcher unaware of the nature of the treatment given.

 

 

9.      Evaluation criteria

 

Evaluation of the patients will be performed on coded evaluation record, devoid of any possible identification of the patient.

 

Evaluation will be done on Day 0 (before start of the treatment, during radiation planning), Week 1 – 6 (once a week during treatment period), Day X (end of treatment), Months 3 (3 month after start of the treatment).

 

Each set of evaluation will be documented on standardised tables, which allow analysis for comparison and will comprise:

 

Day 0: Clinical examination (general clinical examination, including neurological status and Karnofsky performance status; CTC status)

 

Week 1 – 6: Clinical examination, laboratory investigations (blood cell count, hematocrit, Na, K, Cl, creatinin)

 

Day X: Clinical examination, laboratory investigations, quality of live questionnaire (Phase III)

 

Months 3: Clinical examination, laboratory investigations, contrast-enhanced computerised tomography (CT) or magnetic resonance imaging (MRI) scan, quality of live questionnaire (Phase III)

 

 

10. Data and statistical analysis

 

Patients' recurrence free survival will be assessed by clinical monitoring. The individual survival time will be evaluated by contacting treating clinician, general practicians and local registry office.

Statistical tests will be performed two years after the last patient has entered the study:

The differences in patients characteristics and treatment parameters between the treated group with or without HBO will be investigated using the student`s t-test or chi-square-test. Survival curves will be calculated using the Kaplan-Meyer method. Differences in survival curves will be determined using the log-rang test. The Cox proportional hazard model will be used to calculate the relative risk on each variable for survival. Results will be considered significant for p-values <0.05.

 

The time interval between HBO treatment and radiotherapy will be recorded.

Role of hyperbaric oxygen in enhancing radiosensitivity on glioblastoma multiforme

 

Dear patient,

 

you may wish to participate in a study which is being conducted to evaluate if hyperbaric oxygen delivered before conventional radiotherapy affects the outcome.

 

Oxygen has in experimental studies been shown to enhance radiotherapy efficiency.

 

If you accept to participate in the study, you will be selected to participate either in a group of patients who will be given hyperbaric oxygen therapy before radiotherapy or in a group of patients will have no special treatment before each irradiation.

 

Hyperbaric oxygen treatment will mean 30 treatments in a chamber compressed with air. Each treatment takes approximately two hours and will be conducted at the hyperbaric chamber nearest to where you live.

 

If you accept to participate, and if you are selected for hyperbaric oxygen treatment, you will called to the hyperbaric chamber for practical information of how the treatment will be conducted, and an individual treatment plan for you will be put forward.

 

Participation in the study is voluntary and can be stopped whenever you wish without giving any reason.

 

 

I have read the above information, understood the content and accept to participate in the study.
