We are very happy that Dr. Carrie Minnaar Strauss represented Oncotherm at an lmportant South African Conference. She presented a scientific Oncotherm poster at the SASMO (South African Society of Medical Oncology) and SASCRO (South African Society of Clinical Radiation Oncology) Congress that was held from August 7th to 9th, 2015 in Cape Town, South Africa, titled: "Oncothermia - a complex treatment approach". The poster was done together wlth PD Dr. Oliver Szasz. Dr. Minnaar Strauss also represented Oncotherm as exhibitor at a booth and meet many interested doctors.

Wir freuen uns, dass uns Dr. Carrie Minnaar Strauss Oncotherm auf einer wichtigen südafrikanischen Konferenz repräsentiert hat. Sie stellte ein wissenschaftliches Oncotherm Poster auf dem SASMO (South African Society of Medical Oncology) und SASCRO (South African Society of Clinical Radiation Oncology) Kongress vor, der vom 7. - 9. August 2015 in Kapstadt, Südafrika stattfand. Der Titel lautete "Oncothermia - a complex treatment approach". Das Poster wurde gemeinsam mit PD Dr. Oliver Szasz entwickelt. Dr. Minnaar Strauss hat Oncotherm ebenfalls als Aussteller an einem Stand
vertreten und die Fragen vieler interessierter Ärzte beantwortet.

Oncothermia has more than 20 years clinical experience. It has wide range of applications in 30 countries all over the world, distributing their intra-Iuminar, loco-regional and multi-Iocal systems. Despite the market successes the skepticism is vivid just as the complete oncological hyperthermia topic has been for centuries. Oncothermia is a capacitive coupling technology. This technical solution is well-known for almost a century introduced by Siemens in the early thirties of the 20th century. Multiple devices were developed from that time on in Germany, France, the USA, Japan, Italy, etc. but the desired clinical breakthrough was not achieved. A new concept of capacitive coupling was developed by Oncotherm 25
years aga making impedance matching and applying some modern technical and biomedical results, adding permanently the state-of-art knowledge from the latest outcomes of medical researches [1].

The popularity of the device worldwide and the massive number of the highly professional users who work on more than one oncothermia devices produce huge amount of clinical results every day [2], [3], [4], [5]. The published studies show excellent results on advanced cases of lung (NSCL) (more than 400 patients) ; [6], [7], [8], (SCLC) (n=31), [9]) brain gliomas (n=15) [10], (n=140) [11], (n=36) [12], (n=19) [13], advanced sarcomas (n=13) [14], (n=24) [15], advanced liver (n=80) [16], (n=21) [17], (n=60) [18], (n=22) [19], advanced inoperable pancreas tumors [2], (n=26) [21], monotherapy applications when all other possibilities fail, (n= 16) [22], bone-metastasis (case report) [23], prostate tumor [24], [25].

The recently ongoing clinical studies on advanced oncological situations are very promising:
• advanced, relapsed ovarian cancer, (Korean National Cancer Institute, Seoul, Korea)
• advanced cervix tumor (Chonbuk National University Hospital, Korea)
• pharmacokinetic studies (Chonbuk National University Hospital, Korea)
• advanced, relapsed, HIV connected cervical cancer (University of Witwatersrand, Johannesburg,S.    Africa)
• advanced, relapsed esophagus cancer (Chiba University, Chiba, Japan)
• advanced, metastatic breast cancer (Thai National Cancer Institute, Bangkok, Thailand)
• advanced, pancreatic cancer with liver metastases (Thai National Cancer Institute, Bangkok, Thailand)
• advanced breast and gynecology cancer (University of Toyama, Toyama, Japan)
• phase I/II trial breast cancer (Ludwig-Maximillians University, Munich, Germany)
• traditional Chinese medicine and Oncothermia (Clifford Hospital, Guangzhou, China)
• pancreas cancer (Seoul National University Bundang, Seoul, Republic of Korea)
• adenocarcinoma of the lung (Bundang Cha General Hospital, Seoul, Republic of Korea)
• ovarian cancer (National Cancer Institute, Seoul, Republic of Korea)
• epithelial ovarian cancer (Seoul National University Bundang Hospital, Bundang, South Korea)
• sarcoma (Kosin University, Busan, Republic of Korea)
• advanced ovary cancer (Ewha Womans University Cancer Center for woman, Seoul, Republic of Korea)
• inoperable pancreatic cancer (Seoul National University Bundang Hospital, Bundang, South Korea)
• lung adenocarcinoma (Bundang Cha General Hospital, Seoul, Republic of Korea)
Based on these strong data set from clinical studies oncothermia is eligible to be a solid part of the everyday oncologic treatment in many indications. In order to obtain the overall worldwide clinical acceptance further actions are required such as the collection of the prospective and retrospective data from the certified Crnica, studies.

Scientific Topic: Comparison Oncothermia/ Hyperthermia

A complete technical comparison of oncothermia systems with other capacitive hyperthermia systems in the same frequency range is collected in the table below.

# Parameters Traditional Capacitive Hyperthermia (8MHz~13.56MHz) Oncothermia(13.56MHz, modulated)
1 Goal of heating necrosis of tumor apoptosis of malignant cell
2 Heating  methods macro-heating (selected by macroscopic impedance differences) micro-heating (nano-selected by microscopic impedance differences) 
object entire tumor volume  cell membrane of malignant cells
output power over 1W/cm2, (generally >500W)  less than 0.5W/cm2, (generally <250W) 
3 Focusing patient movement smeared by patient movements current follows movement of patient
time effect heat-spreads over time  low heat-spreading due to micro-mass-effect
4 Electrode system symmetry geometric and electric symmetry  geometric and elctric asymmetry
electric parameter voltage dominating current centered
coupling plane-wave coupling impedance coupling 
5 Penetration depth (determined by electrode setting) shorter determined by the plane waves  longer determined by the RF-current-density
6 Selectivity by object conductivity of malignant tissue theoretically works, but RF voltage centered coupling of the electrodes and the macro-heating cancel the effect (overheating cancels the selectivity and the effect) effectively works by micro-heating with strong impedance coupling 
permittivity of cells
by RF characteristics β-dispersion on membrane
by pathologic pattern fractal modulation  not built-in built-in
7 Physiologic effect effect on blood flow first vasodilation, then vasocontraction over a threshold temperature, uncontrollable mild overall heating, only slight vasodilatation, controllable below the vasocontraction threshold
effect of homeostatic feedbacks strong feedback of reestablishing homeostatic equilibrium, which works against the heating weak homeostatic counter-actions, therefore hyperthermia acts effectively
immune activation immune-cells are active only below 40°C, therefore unworkable working due to mild heat-effect
surface cooling strong cooling with extra bolus solution homeostatic cooling, no extra (secondary) bolus cooling, keeping the homeostatic equilibrium 
8 Heating result on cell-death dominantly necrosis, minor apoptosis by internal apoptotic pathways (in mitochondria)  dominantly apoptosis  happens via external pathways (surface of cell membrane)
9 Dose facility  temperature (°C)[CEM43CTx (min)] energy like in case of the ionizing radiation  (Gy=J/Kg)
10 Safety and side effect risk of invasion broken adherent connections and collapsed cytoskeleton facilitate the invasion of malignant cells reestablished adherent connections and rebuilt cytoskeleton of malignant cells blocks the invasion of malignant cells
risk of metastases high vasodilatation might induce dissemination of malignant cell low vasodialtion doesn't force dissemination of malignant cells
risk of burning high-risk of  burning toxicity low-risk of burning toxicity
11 Complementary applications chemotherapy the forced over-threshold temperature (>40°C) makes vasocontraction, limits the anyway hard drug delivery to the tumor good synergy with the drug-deliveries extending the chemotaxis with electrotaxis
radiotherapy the forced over-threshold temperature (>40°C) creates hypoxia and decreases the efficacy of radiotherapies  no hypoxia is presented, the radio-sensitization is increased
12 Immune activity immune effects uncontrolled, necrosis reference (CEM43°CTx) [calibrated in-vitro] massive production of apoptotic bodies and damage associated molecular pattern (DAMP): mHSP70 + HMGB1 + Calreticulin
bystander and abscopal effect  rare abscopal phenomena frequent abscopal phenomena, immunogeric cell-death (ICD)
