Brief summary: Using moderate whole-body hyperthermia (mWBH) in tumor patients to see the influence on circulating tumor cells, tumor response, quality of life, fatigue, psyche, immune response and tumor microenvironment

Detailed description: Moderate whole-body hyperthermia (mWBH) is considered to be a very well-tolerated treatment. It has been used in numerous naturopathic and oncological practices for decades. It is also being used more and more with an increasing number of non-oncological diseases. A recently published randomized study was able to prove a sustained positive effect of whole-body hyperthermia in patients with depressive episodes. However, there are no clinical studies that demonstrate the benefit of this measure with regard to oncological treatment. There is also a lack of clarity about the mechanism of action of mWBH. A positive modification of the tumor microenvironment (increased perfusion, reduced interstitial pressure) and an increased activation of tumor-killing immune cells could be shown preclinically - however, a clinical evaluation of these mechanisms has not yet taken place.

This randomized study aims to evaluate the effect of mWBH on the tumor response of patients suffering from advanced cancer. The aim of the study is to demonstrate an improvement in the therapy response rate three months after the end of therapy through the additional use of mWBH, measured by a positive influence on the change in the number of circulating tumor cells from the time before therapy to the time three months after the start of therapy.

Quality of life reported by patients, recorded by the FACT-G questionnaire, as well as psychological parameters, fatigue and various other parameters with regard to an increase in the effect on the tumor are evaluated as secondary endpoints. All patients also receive serial immune monitoring. For this purpose, blood samples are taken before therapy and several times during the course of the therapy, which are then evaluated with regard to cytokines, immunological proteins and specific subgroups of immune cells.

The patients all receive guideline-based therapy in line with current internal practice. In addition to standard therapy, patients are randomized 1:1 and, if randomized to the mWBH arm, receive an additional 3-4 mWBH sessions during their oncological treatment. A total of six different patient groups are included, all with palliative therapy intentions (patients with multiple metastatic malignant melanoma before initiation of immunotherapy (checkpoint blockade), patients with metastatic or inoperable pancreatic carcinoma for whom first-line chemotherapy with FOLFIRINOX is planned, patients before palliative radiation therapy for a hormone-receptor-positive breast cancer who have previously received palliative systemic therapy and have at least one other tumor lesion in addition to the one that was irradiated, patients with metastatic sarcoma in whom ablation of the metastases is not possible and who are receiving palliative first-line therapy using Doxorubicin is planned to treat patients with metastatic or loco-regionally recurrent HPV-associated squamous cell carcinoma of the head and neck region, cervix, anus or vulva, for whom no local therapy methods are possible and palliative first-line platinum therapy is planned, patients with metastatic castration-resistant prostate cancer with progressive disease after exhaustion of recommended therapy options for whom a therapeutic trial with lutetium-177-PSMA has been indicated). A total of at least 72 patients, stratified into the 6 subgroups mentioned above, should be evaluated in the study, who should receive three to four sessions of mWBH in addition to standard oncological treatment. In order to obtain the necessary minimum number of patients in all subgroups, the inclusion of 80 patients in the study is necessary with an expected drop-out rate of 10%.

In order to record the effect of mWBH on quality of life, fatigue and depression, study participants must fill out a questionnaire on quality of life, fatigue and depression before the start of therapy, at the end of treatment and two weeks after therapy. To evaluate the influence of mWBH on immune parameters, patients also receive additional blood samples before the start of therapy, at the end of therapy and at two follow-up times, which can normally be combined with routine blood samples.

For further risk stratification, the samples obtained after an operation or biopsy can be used for further analysis. This examination means no additional intervention and no increased risk for the patient, since these have already been carried out routinely. Patients have the option of expressly agreeing to the removal and further use of these biomarkers or rejecting them as part of the declaration of consent.

Eligibility criteria: Inclusion Criteria:

* The general condition of the patients must be sufficient for multimodal treatment (corresponding to WHO status 0-2)
* Tumordisease in a palliative setting of the following 6 groups:

  1. Malignant melanoma, treatment-naive stage IV with multiple metastases and missing BRAF-V600 mutation. With indication for initiation of immunotherapy using PD-1 and CTLA-4 antibody therapy.
  2. Patients with metastatic or inoperable pancreatic cancer, who are planning first-line chemotherapy with FOLFIRINOX is.
  3. Patients with an indication for palliative radiation therapy extracranial, tumor manifestation with a prescribed radiation dose of 30 to 36 Gy due to hormone receptor-positive carcinoma of the breast, patients must have at least one additional (marker) lesion not treated with radiation.
  4. Patients with metastatic high-grade sarcoma for whom metastasis-directed ablative therapy methods are not possible and palliative first-line therapy with doxorubicin.
  5. Patients with metastatic or loco-regionally recurrent HPV-associated squamous cell carcinoma (of the head and neck region, cervix, anus or vulva) for whom local therapies are not possible and for whom palliative first-line therapy containing platinum is planned.
  6. Patients with metastatic, castration-resistant prostate cancer, with progressive disease after exceeding the recommended therapy options for which a therapy attempt with lutetium-177-PSMA was indicated.

Exclusion Criteria:

* Presence of contraindications to simultaneous chemotherapy or whole-body hyperthermia
* Serious or active comorbidities that could interfere with treatment or understanding of the nature and content of the study, for example:

  * Chronic inflammatory bowel disease
  * Acute infections
  * Serious cardiovascular or pulmonary comorbidities
  * Mental illnesses, showing the proper Study participation or recording the nature of the study to make impossible
  * Presence of cerebral metastasis
  * Diabetes mellitus with risk of end-organ damage
