Head and neck cancers generally begin in the squamous cells that line the moist, mucosal surfaces inside the head and neck.<\/p>

Head and neck cancers are categorized based on the area of the head or neck where they begin. These areas include:\u00a0Oral cavity<\/strong>,\u00a0Pharynx<\/strong>,\u00a0Larynx<\/strong>,\u00a0Paranasal sinuses, nasal cavity and<\/strong>,\u00a0Salivary glands<\/strong>.<\/p>

Cancers of the brain, eye, thyroid gland, as well as those of the scalp, bones, and muscles of the head and neck are not generally classified as head and neck cancers.<\/p><\/div><\/div><\/div><\/div><\/div><\/div><\/div><\/div>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

Below are the details of some of these treatments:<\/p><\/div><\/div><\/div>

4D RADIOTHERAPY:\u00a0<\/span><\/h2>

The treatment is synchronized with the patient\u2019s breathing.<\/span> This innovative radiotherapy technique benefits patients with tumors in mobile areas by taking into account\u00a0the patient\u2019s respiratory cycle.<\/span><\/p>

To achieve this, the imaging systemcaptures images of the treatment area in the various positions it may take during the breathing cycle.\u00a0<\/span><\/p>

This technique is used in injuries in which the treated area has a lot of involuntary mobility.<\/p>

Through the use of IMRT, or Intensity-Modulated Radiation Therapy, patients receive high doses of treatment with millimeter-level precision.<\/p>

This translates into fewer side effects, better preservation of healthy tissue, and greater optimization of the patient's treatment time.<\/em><\/p>

In addition, with the new 4D radiotherapy technology, the patient's breathing cycles are taken into account during treatment planning.<\/p>

In this way, the equipment and dosage are calibrated to deliver treatment doses during the most optimal phases of the respiratory cycle, increasing the effectiveness and precision of treating mobile tumors or lesions.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

IMAGE GUIDED RADIOTHERAPY (IGRT):\u00a0<\/span><\/h2>

Combina im\u00e1genes de tomograf\u00edas computarizadas con radioterapia durante cada sesi\u00f3n de tratamiento, e<\/span>sto permite determinar la forma m\u00e1s precisa posible el \u00e1rea a tratar.<\/span><\/p>

Esta tecnolog\u00eda ubica al paciente en el punto exacto para irradiar casi de forma exclusiva la lesi\u00f3n y no da\u00f1ar \u00f3rganos importantes.<\/p>

Esta tecnolog\u00eda no est\u00e1 disponible en sistemas de radioterapia convencionales.<\/p>

INTENSITY MODULATED RADIOTHERAPY (IMRT):\u00a0<\/span><\/h2>

This technology allows for the delivery of precise radiation doses to a tumor or specific areas within a tumor while reducing doses to healthy tissues.<\/p>

Combined with the advantages of our linear accelerator, which offers the so-called Arc Therapy (the ability to irradiate a lesion from 360 different angles), it guarantees the highest quality in treatment.<\/p>

RADIOSURGERY:\u00a0<\/span><\/h2>

High doses in few treatments (1-5 sessions). Radiosurgery or SBRT is used in the treatment of small to medium-sized tumors.<\/p>

It is a non-surgical procedure that delivers highly focused radiation at much higher doses in just one or a few treatments.<\/p>

This treatment is made possible thanks to the development of highly advanced technologies that allow the delivery of maximum doses within the target while minimizing the dose received by the surrounding healthy tissue.<\/p>

The goal is to deliver doses that destroy the tumor and achieve maximum local control.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

C\u00e1ncer de Cabeza y Cuello \u00bfQu\u00e9 es el c\u00e1ncer de cabeza y cuello? Los c\u00e1nceres de cabeza y cuello, generalmente, comienzan en las c\u00e9lulas escamosas que revisten las superficies h\u00famedas y mucosas del interior de la cabeza y del cuello. Los c\u00e1nceres de cabeza y cuello se categorizan, de acuerdo a la zona de la cabeza o del cuello en la que empiezan. Estas zonas son:\u00a0Cavidad oral,\u00a0Faringe,\u00a0Laringe,\u00a0Senos paranasales, cavidad nasal y,\u00a0Gl\u00e1ndulas salivales. Los c\u00e1nceres de cerebro, ojo, gl\u00e1ndula tiroides as\u00ed como los de cuero cabelludo, huesos y m\u00fasculos de la cabeza y cuello no se clasifican generalmente como c\u00e1ncer de cabeza y cuello. A continuacio\u0301n, el detalle de algunas de estos tratamientos: RADIOTERAPIA EN 4D:\u00a0 Sincroniza el tratamiento con la respiraci\u00f3n del paciente. Esta novedosa t\u00e9cnica de radioterapia beneficia a pacientes con lesiones en tumores m\u00f3viles al considerar\u00a0el ciclo respiratorio del paciente. Para ello el sistema de adquisici\u00f3n de im\u00e1genes obtiene im\u00e1genes con la zona de tratamiento en las distintas posiciones que puede adoptar.\u00a0 Esta t\u00e9cnica se emplea en lesiones en las que la zona tratar tiene mucha movilidad involuntaria. Mediante la utilizaci\u00f3n de IMRT o Radioterapia de Intensidad modulada los pacientes reciben altas dosis de tratamiento de forma milim\u00e9tricamente precisa. Esto se traduce en menos efectos secundarios, mejor preservaci\u00f3n del tejido sano y mayor optimizaci\u00f3n del tiempo de tratamiento del paciente. Sumado a esto, con la nueva tecnolog\u00eda de radioterapia en 4D los ciclos respiratorios del paciente son considerados en la planificaci\u00f3n del tratamiento. De esta forma el equipo y dosis se calibrar\u00e1n para aplicar las dosis de tratamiento en las fases m\u00e1s \u00f3ptimas del ciclo respiratorio, aumentando la efectividad y precisi\u00f3n del tratamiento de aquellos tumores o lesiones m\u00f3viles. RADIOTERAPIA GUIADA POR IM\u00c1GENES (IGRT):\u00a0 Combina im\u00e1genes de tomograf\u00edas computarizadas con radioterapia durante cada sesi\u00f3n de tratamiento, esto permite determinar la forma m\u00e1s precisa posible el \u00e1rea a tratar. Esta tecnolog\u00eda ubica al paciente en el punto exacto para irradiar casi de forma exclusiva la lesi\u00f3n y no da\u00f1ar \u00f3rganos importantes. Esta tecnolog\u00eda no est\u00e1 disponible en sistemas de radioterapia convencionales. RADIOTERAPIA DE INTENSIDAD MODULADA (IMRT):\u00a0 Esta tecnolog\u00eda permite administrar dosis de radiaci\u00f3n precisas a un tumor o a \u00e1reas espec\u00edficas dentro de un tumor y reducir las dosis en tejidos sanos. Combinada con las ventajas de nuestro acelerador lineal que ofrece la llamada Arco Terapia, (que es la capacidad de irradiar una lesi\u00f3n desde 360 diferentes \u00e1ngulos), garantiza la m\u00e1s alta calidad en el tratamiento. RADIOCIRUG\u00cdA:\u00a0 Altas dosis en pocos tratamientos (1-5 sesiones). La Radiocirug\u00eda o SBRT se utiliza en el tratamiento de tumores de tama\u00f1o peque\u00f1o a mediano. Es un procedimiento no quir\u00fargico que entrega radiaci\u00f3n sumamente enfocada en dosis mucho m\u00e1s altas y en solamente uno o pocos tratamientos. Este tratamiento es posible gracias al desarrollo de tecnolog\u00edas altamente avanzadas que permiten la entrega de dosis m\u00e1ximas dentro del blanco, mientras se reducen al m\u00e1ximo la dosis que recibe le tejido sano circundante. El objetivo es administrar dosis que destruyan el tumor y logren un m\u00e1ximo control local.<\/p>","protected":false},"author":1,"featured_media":278,"comment_status":"open","ping_status":"open","sticky":false,"template":"elementor_header_footer","format":"standard","meta":{"_acf_changed":false,"inline_featured_image":false,"_joinchat":[],"footnotes":""},"categories":[6],"tags":[],"class_list":["post-277","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-tipos-cancer"],"acf":[],"yoast_head":"\nC\u00e1ncer de Cabeza y Cuello - SigloXXI - Centro Me\u0301dico de Radioterapia<\/title>\n<meta name=\"description\" content=\"Tejidos tan vitales requieren la m\u00e1s alta precisi\u00f3n que garantice los menores efectos secundarios.
