Chemotherapy

Chemotherapy (chemo) involves using anticancer drugs that can be given intravenously (injected into your vein) or by mouth. In chemotherapy, the drugs pass through the bloodstream to reach cancer cells in most parts of the body.

Chemotherapy may be given before surgery (neoadjuvant) or after surgery (adjuvant).

It can be combined with other treatments such as radiotherapy

Oncothermia combined with chemotherapy for the treatment of recurrent cervical cancer

Researchers compared the effect of Oncothermia combined with conventional chemotherapy versus chemotherapy alone in patients with cervical cancer.

Cáncer cérvix Oncothermia

Dr. Lee’s team, from Department of Radiation Oncology, Institute of Medical Sciences, Chonbuk Medical University, South Korea, has recently published in the journal Oncology Letters the results on the complementary use of Oncothermia in recurrent Cervix Cancer previously treated with radiotherapy.

The present study was performed to evaluate the effect of Oncothermia combined with conventional chemotherapy compared with chemotherapy alone on recurrent cervical cancer previously treated with irradiation.

Method

A total of 20 patients, aged 36-71 years, with cervical cancer were treated with chemotherapy. Of these, 18 patients were treated with chemotherapy combined with Oncothermia. In addition, the equipment used was: EHY2000 (Oncotherm GmbH, Troisdorf, Germany). And the frequency was 13.56 MHz, with the circular electrode diameter of 30 cm.

In addition, local metastases (including para-aortic lymph nodes and adjacent pelvic lymph nodes) were considered in the inclusion criteria of the study. Also, patients with distant metastases were excluded.

For the study, Oncothermia was applied 3 times a week for 60 minutes from the start of chemotherapy. A total of 36 sessions were carried out.

Results

The overall response (complete remission + partial remission + stable disease/progressive disease) to treatment was significantly greater in the group of patients who underwent chemotherapy combined with Oncothermia (P=0.0461). Then, Oncothermia was shown to be more effective in the treatment of local metastases (lymph nodes). No complications with the use of Oncothermia were reported.

Conclusion

In conclusion, in patients with recurrent cervical cancer treated with radiotherapy, the overall response rate to treatment is significantly higher in patients who combined chemotherapy with Oncothermia compared to those who only received chemotherapy.

Chemotherapy and Oncothermia association

Lower and less toxic doses of chemotherapy by combining it with Oncothermia and complementary treatments.

Modelo EHY-2000 de Oncothermia

Professor Dr. med. Alexander Herzog, Chief-physician, Fachklinik Dr. Herzog, Germany has published a recent clinical study in the Oncothermia journal. He also presented it at the 35th ICHS, Guangzhou, China, 2017. The study explains the results in the use of lower and less toxic doses of chemotherapy when combined with hyperthermia and complementary treatments.

Electro-hyperthermia (Oncothermia) is an important tool for improving the efficacy of chemotherapy and radiation in cancer.

Numerous studies have been published on Oncothermia treatment in cell cultures, in animal experiments, but also in patients. Furthermore, these studies include randomised studies, phase 2 studies, but also many successful case reports that provide evidence for the benefit of Oncothermia.

Methods:

Oncothermy means heating the cancerous tissue up to 42°C (107.6°F). In several experiments, it has been shown that chemotherapy works more efficiently if the temperature of the cancer tissue is increased. There can be a linear or even exponential increase in the activity of cytostatic drugs.

The Oncotherm device with 13.56 MHz and energies up to 150 watts was used. The local treatment takes 1 hour for each session. In addition, such treatment can be repeated frequently (the interval between 2 treatments should be at least 48 hours to avoid thermal tolerance).

Chemotherapy is administered simultaneously with a local Oncothermia session.

Results for a selection of different cancers:

♦ ENT-Cancers:

The standard chemotherapy in these cases would be a rather toxic 5-day programme of cisplatin together with 5-FU as a continuous infusion. Together with oncothermia, a 4-day programme would be sufficient.

♦ Non-small cell lung cancer:

The dosing regimen would follow platinum-based chemotherapy, but the doses of Carboplatin and Gemcitabine or Vinorelbine could be reduced by approximately 20%, if applied together with Oncothermia.

♦ Colorectal cancer:

Chemotherapy protocols in colorectal cancer are mainly the FOLFOX protocol and the Folfiri protocol, which can be combined with Bevacizumab or Cetuximab antibodies. Together with Oncothermia, the dose of Oxaliplatin would be kept at the standard level. Irinotecan could be reduced. 5-FU administered as a chronomodulated treatment at night with 50% of the dose between 2 a.m. and 6 a.m. could also be significantly reduced. In addition, Capecitabine can be used together with Oncothermia at a reduced dose.

♦ Ovarian and cervical cancers:

In ovarian and cervical cancer, the standard chemotherapy is Carboplatin and the neurotoxic drug Paclitaxel. Together with Oncothermia, Carboplatin could be combined with a less toxic dose of Cyclophosphamide, which is a drug with potentiation of its activity under hyperthermic conditions.

♦ Breast cancer:

In one study, it has been shown that 70-80% of breast cancer patients respond to a treatment programme with local oncothermia together with moderate doses of chemotherapy.

Reduces toxicity

In conjunction with oncothermia, it is possible to use chemotherapy in more moderate doses. This reduces toxicity. Above all, it helps patients in particular in the palliative situation to preserve quality of life. It also allows for more regular treatments and for a longer period of time which is possibly very important to improve survival times.

Ascending colon cancer treated with Oncothermia and Chemotherapy

The following is the clinical case of a 63-year-old male patient. The diagnosis is ascending colon cancer with liver metastases. He was treated with chemotherapy, combined with oncothermia.

Diagnosis

In November 2016, he presented with an ascending colon neoplasm. Consequently, he underwent a right hemicolectomy. As a result, the biopsy showed infiltrating adenocarcinoma.

Subsequently, in January 2017, she presented with elevated CEA. A CT scan revealed mesenteric and retroperitoneal lymphadenopathy. Multiple liver metastases were also observed, the largest measuring 35 mm.

Treatment

Immediately, in February 2017, he started treatment with chemotherapy (FOLFOX) and 4 sessions of 90-minute oncothermia.

The CT scan of April 2017 showed resolution of the mesenteric and retroperitoneal adenopathies. There was also a significant decrease in the multiple liver metastases, the largest being 14 mm.

Result

Finally a normalisation of tumour markers is detected.

Breast Cancer treated with Chemotherapy and Oncothermia

The following is the clinical case of a 51 year old female patient. The diagnosis is infiltrating ductal carcinoma of the left breast. She was treated with chemotherapy, combined with oncothermia.

Diagnosis

She presented in May 2016 with breast cancer, infiltrating ductal carcinoma of the left breast. Consequently, the MRI shows multiple and extensive irregular confluent foci. In addition, the cancer forms a mass measuring 79 mm x 52 mm x 58 mm extending to the nipple-areola complex with infiltration of the dermis.

Treatment

In June 2016 she started chemotherapy with Paclitaxel and Trastuzumab. Subsequently, in August 2016, oncothermia treatment was started, with 60-minute sessions.

Result

In October 2016 a breast MRI is performed for control, after the administration of 9 sessions of chemotherapy and 6 sessions of 60-minute oncothermia.

The result of the MRI shows disappearance of the tumour mass indicating a complete response to treatment.

Consequently, the patient refuses surgical treatment as there is no tumour mass and continues with radiological controls. In October 2018 the patient has shown no signs of recurrence.

Rectal Cancer treated with Oncothermia and Surgery

The following is a case report of a 67 year old male patient. The diagnosis is rectal cancer. He was treated with oncothermia and surgery.

Diagnosis

He presented with rectal adenocarcinoma in February 2018. In particular, it is a tumour 6 cm from the anal margin occupying one third of the intestinal lumen. In addition, the ultrasound scan showed serosal involvement, and it was classified as stage III.

Treatment

Preoperative chemotherapy and radiotherapy are recommended to reduce the tumour volume and perform surgical resection.

In this case, the patient categorically rejects chemotherapy and radiotherapy. On the contrary, he decided to start treatment with Oncothermia, with the aim of reducing the tumour volume and undergoing surgery.

He underwent 20 sessions of 90-minute oncothermia for 2 months, with a frequency of 3 sessions per week.

Result

Ultrasound endoscopy in May 2018 showed a T1 polypoid lesion. In September 2018 he underwent endoanal resection of the polypoid lesion with all the margins of the piece free of tumour.
