Hyper thermia means a temperature higher than the normal organic structure temperature. The temperatures can be up to 113 F.Its application is a therapy used in medical field in this therapy the organic structure tissues are exposed to high temperatures scopes at which the ( hyper mitotic ) tumour cells are destroyed or made more sensitive to the other malignant neoplastic disease interventions e.g. radiation or chemotherapy etc. It is largely used as an accessory therapy.

“ It has been shown that increased heat has made malignant neoplastic disease cells more antiphonal to radiation, ” says Theodore L. DeWeese, MD, professor and president of the section of radiation oncology and molecular radiation scientific disciplines at The Sydney Kimmel Comprehensive Cancer Center at Johns Hopkins in Baltimore, Maryland.

Types: 1. External: heat applied from outside organic structure e.g. by microwaves, ultrasound, radiofrequencies etc.

2. INTERNAL: substances moving as heat beginning for organic structure are inserted in the organic structure.

Other 3 major Types are:

Local hyperthermy ( external, intraluminal and interstitial )

regional hyperthermy ( DEEPTISSUE, regional perfusion, uninterrupted hyperthermy peritoneal perfusion )

whole-body hyperthermy

Benefits:

synergism with chemotherapeutic drugs and ionising radiation

low host toxicity

easiness of control ( heating precisenesss in the scope of A±0.1A°C and specific definable localised countries )

low opposition ( chemotherapeutic and hyperthermic opposition ) .

Here are some positions of scientists sing benefits of hyperthermy:

“ The patients having the targeted heat therapy fared better on all result measurings, ” Prof Issels said. “ Almost three old ages after get downing intervention, they were 42 % less likely to see a return of their malignant neoplastic disease at the same site or to decease than those who were acquiring chemotherapy entirely, lasting an estimated 120 months before local patterned advance of their disease, compared with an estimated 75 months. Similarly, the mean length of clip that patients remained disease free was 32 months in the group that got both interventions, compared with 18 months in the group that got chemotherapy entirely – an betterment of 30 % . ” hypertext transfer protocol: //www.bichercancerinstitute.com/hyperthermia_resources.html

A new article in Current Option in Oncology Current Option in Oncology 2008, 20: pages 438-443.has highlighted the usage of BSD Medical ‘s BSD-2000 hyperthermy system in handling patients with high hazard soft tissue sarcomas.

The article entitled “ Regional hyperthermy in bad soft tissue sarcomas ” was authored by Rolf D Issels, MD, PhD of the University Hospital Medical Center Grosshadern and Helmholtz Zentrum Munchen-German Research Center for Environmental Health, Munich, Germany. The writer stated that, “ The principle for the combination of cytotoxic drugs with hyperthermy ( addition of temperature in the scope of 40 to 44 grades C ) is based on experimental and clinical grounds that heat additions killing of cells by direct thermic toxicity and shows thermic sweetening of drug efficaciousness. ”

Adverse EFFECTS ;

One of the challenges in this therapy is presenting the appropriate sum of heat to the right portion of the patient ‘s organic structure and commanding the temperature

Externally applied may hold following hazards: blisters heal rapidly and Burnss which do non. Trouble, weariness, blood coagulums, swelling, shed blooding etc.

Whole organic structure hyperthermy may do terrible conditions like diarrhoea, CVD ( cardiovascular diseases ) purging nausea tan etc. overheating may ensue into harm to environing tissues and if ruptures so toxicity.

If used conscientiously it has no serious side effects.

Mechanism:

Over warming of malignant neoplastic disease cells causes deficiency of O taking to overcalcification of het tumour cells and doing deficiency of foods ladling to break of metabolic procedure of cells ensuing in programmed cell death ( cell decease ) . When used with other therapies it slows down the cell procedure and causes change in cell wall by heatshockproteins and so malignant neoplastic disease cells react efficaciously to the therapies.

Addition in heat causes increase in blood flow to warmed country duplicating the perfusion in tumour cells by many creases heightening the consequence of medicine to these countries Carolyn Freeman ; Halperin, Edward C. ; Brady, Luther W. ; David E.

Use OF GLODINIUM IN HYPERTHERMIA THERAPY:

IN article

Gadolinium ( 3+ ) -doped mesoporous silicon oxide nanoparticles as a possible magnetic resonance tracer for supervising the migration of root cells in vivo. By Shen Y, Shao Y, He H, Tan Y, Tian X, Xie F, Li L.

The scientists investigated the tracking potency of MRI investigation made of gadolinium-doped mesoporous silicon oxide MCM-41 ( Gd ( 2 ) O ( 3 ) @ MCM-41 ) nanoparticles in vivo.

This survey confirmed that these atoms can be the ideal vector for long term MRI trailing of mesenchymal root cells and nervous root cells.

The usage of magnetic nanoparticles can get the better of the trouble in spacial adjusting of power soaking up by cancerous tissue. Use of magnetic stuffs in hyperthermy was foremost proposed in 1957 ( Gilchrist R. K. , et Al. 1957 )

Magnetic Hyperthermia:

Magnetic field is used in this technique for killing malignant neoplastic disease cells. The temperature scope is 42-46 C. Magnetic stuffs used are ferro- , ferri- magnetic and ace paramagnetic. The magnetic stuffs are made with nanometer size so called Magnetic Nanoparticle ( MNP ) these can come in the cancerous cells ( diameter scope 10 to 100 microns ) . Their heat capacity depends on ; magnetocrytalline anisotropy, atom size and microstructure.

NeA? EL explained it as: Magnetic nanoparticles are designed to selectively be absorbed in tumour. Once the stuffs are in the tumour, they agitate under an alternating magnetic field bring forthing heat within tumour. Heat coevals is because of minute relaxatiomechanical rotary motion, taking to the devastation of tumour cells.

Supraparamagnetic nanoparticles are ideal for hyperthermy malignant neoplastic disease interventions so they do non aggregate and so make non impede to take nanoparticles from organic structure.

MOREOVER harmonizing to a scientist Koziara nanoparticles besides significantly cross the BBB so used in handling Brain tumours.

Nano atoms can besides be combined with viruses 20-450nm in size, proteins 5-50nm in size and cistrons 10-100nm long. ( Pankhurst ) .

MAGNETIC FLUID HYPERTHERMIA is technique in which the fluid with nanoparticles is injected in the organic structure.
