Ето накратко какво означават различните стадии на рака на маточната шийка: Стадий 0 означава, че раковите клетки се намират само по повърхността на шийката на матката. Повече инвазивни видове рак са разделени в четири етапа. Стадий I е, когато ракът не се е разпространил извън шийката на матката. Стадий II означава, че туморът се е разпространил в горната част на вагината. При стадий III туморът се простира в долната част на вагината и може да блокира пътя на урината. В стадий IV туморът е достигнал на пикочния мехур или ректума, или раковите клетки са се разпространили и в други части на тялото и са формирали нови тумори. Ракът на маточната шийка в ранен стадий може да се лекува успешно. Изборът на лечение и дългосрочният резултат (прогноза) на тези тумори зависят от вида и стадият. Възрастта, общото здраве, качеството на живот, както и желанието за бъдеща бременност трябва да бъдат взети предвид. Видове лечение Лечение избор за рак на шийката на матката може да бъде единична терапия или комбинация от терапии, като например: • операция за отстраняване на тумора. Видът на операцията зависи от местоположението и стадия на рака на шийката на матката; • лъчетерапия – използва се за определени стадии, често се комбинира с хирургия; • хеморадиация – комбинация от химиотерапия и лъчелечение. Често се използва за лечение както при ранен, така и при късен стадий на рак на маточната шийка; • химиотерапия – прилагат се лекарства, които убиват раковите клетки. Химиотерапията се използва за лечение на напреднал рак на шийката на матката.

Cancer of the thyroid is a disease in which cancer (malignant) cells are found in the tissues of the thyroid gland. The thyroid gland is at the base of the throat. It has two lobes, one on the right side and one on the left. The thyroid gland makes important hormones that help the body function normally. Cancer of the thyroid is more common in women than in men. Most patients are between 25 and 65 years old. People who have been exposed to large amounts of radiation, or who have had radiation treatment for medical problems in the head and neck have a higher chance of getting thyroid cancer. The cancer may not occur until 20 years or longer after radiation treatment. A doctor should be seen if there is a lump or swelling in the front of the neck or in other parts of the neck. If there are symptoms, a doctor will feel the patient's thyroid and check for lumps in the neck. The doctor may order blood tests and special scans to see whether a lump in the thyroid is making too many hormones. The doctor may want to take a small amount of tissue from the thyroid. This is called a biopsy. To do this, a small needle is inserted into the thyroid at the base of the throat and some tissue is drawn out. The tissue is then looked at under a microscope to see whether it contains cancer. There are four main types of cancer of the thyroid (based on how the cancer cells look under a microscope): papillary, follicular, medullary, and anaplastic. The chance of recovery (prognosis) depends on the type of thyroid cancer, whether it is just in the thyroid or has spread to other parts of the body (stage), and the patient's age and overall health. Some types of thyroid cancer grow much faster than others. The genes in our cells carry the hereditary information from our parents. An abnormal gene has been found in patients with some forms of thyroid cancer. If medullary thyroid cancer is found, the patient may have been born with a certain abnormal gene which may have led to the cancer. Family members may have also inherited this abnormal gene. Tests have been developed to determine who has the genetic defect long before any cancer appears. It is important that the patient and his or her family members (children, grandchildren, parents, brothers, sisters, nieces and nephews) see a doctor about tests that will show if the abnormal gene is present. These tests are confidential and can help the doctor help patients. Family members, including young children, who don't have cancer, but do have this abnormal gene, may reduce the chance of developing medullary thyroid cancer by having surgery to safely remove the thyroid gland (thyroidectomy). Stages of cancer of the thyroid Once cancer of the thyroid is found (diagnosed), more tests will be done to find out if cancer cells have spread to other parts of the body. This is called staging. A doctor needs to know the stage of the disease to plan treatment. The following stages are used for papillary cancers of the thyroid: Papillary and Follicular Thyroid Cancer in Patients Younger than 45 Years of Age: Stage I Papillary and Follicular In stage I papillary and follicular thyroid cancer, the tumor is any size, may be in the thyroid, or may have spread to nearby tissues and lymph nodes. Cancer has not spread to other parts of the body. Stage II Papillary and Follicular In stage II papillary and follicular thyroid cancer, the tumor is any size and cancer has spread from the thyroid to other parts of the body, such as the lungs or bone, and may have spread to lymph nodes. Papillary and Follicular Thyroid Cancer in Patients Older than 45 Years of Age: Stage 1 Papillary and Follicular In stage I papillary and follicular thyroid cancer, cancer is found only in the thyroid and the tumor is 2 centimeters or smaller. Stage II Papillary and Follicular In stage II papillary and follicular thyroid cancer, cancer is only in the thyroid and the tumor is larger than 2 centimeters but not larger than 4 centimeters. Stage III Papillary and Follicular In stage III papillary and follicular thyroid cancer, either of the following is found: - the tumor is larger than 4 centimeters and only in the thyroid or the tumor is any size and cancer has spread to tissues just outside the thyroid, but not to lymph nodes; or - the tumor is any size and cancer may have spread to tissues just outside the thyroid and has spread to lymph nodes near the trachea or the larynx (voice box). Stage IV Papillary and Follicular Stage IV papillary and follicular thyroid cancer is divided into stages IVA, IVB, and IVC. - In stage IVA, either of the following is found: - the tumor is any size and cancer has spread outside the thyroid to tissues under the skin, the trachea, the esophagus, the larynx (voice box), and/or the recurrent laryngeal nerve (a nerve with two branches that go to the larynx); cancer may have spread to nearby lymph nodes; or - the tumor is any size and cancer may have spread to tissues just outside the thyroid. Cancer has spread to lymph nodes on one or both sides of the neck or between the lungs. - In stage IVB, cancer has spread to tissue in front of the spinal column or has surrounded the carotid artery or the blood vessels in the area between the lungs; cancer may have spread to lymph nodes. - In stage IVC, the tumor is any size and cancer has spread to other parts of the body, such as the lungs and bones, and may have spread to lymph nodes. Stage 0 medullary thyroid cancer is found only with a special screening test. No tumor can be found in the thyroid. Stage I medullary thyroid cancer is found only in the thyroid and is 2 centimeters or smaller. In stage II medullary thyroid cancer, either of the following is found: - the tumor is larger than 2 centimeters and only in the thyroid; or - the tumor is any size and has spread to tissues just outside the thyroid, but not to lymph nodes. In stage III medullary thyroid cancer, the tumor is any size, has spread to lymph nodes near the trachea and the larynx (voice box), and may have spread to tissues just outside the thyroid. Stage IV medullary thyroid cancer is divided into stages IVA, IVB, and IVC. - In stage IVA, either of the following is found: - the tumor is any size and cancer has spread outside the thyroid to tissues under the skin, the trachea, the esophagus, the larynx (voice box), and/or the recurrent laryngeal nerve (a nerve with 2 branches that go to the larynx); cancer may have spread to lymph nodes near the trachea or the larynx; or - the tumor is any size and cancer may have spread to tissues just outside the thyroid. Cancer has spread to lymph nodes on one or both sides of the neck or between the lungs. - In stage IVB, cancer has spread to tissue in front of the spinal column or has surrounded the carotid artery or the blood vessels in the area between the lungs. Cancer may have spread to lymph nodes. - In stage IVC, the tumor is any size and cancer has spread to other parts of the body, such as the lungs and bones, and may have spread to lymph nodes. Anaplastic thyroid cancer grows quickly and has usually spread within the neck when it is found. Stage IV anaplastic thyroid cancer is divided into stages IVA, IVB, and IVC. - In stage IVA, cancer is found in the thyroid and may have spread to lymph nodes. - In stage IVB, cancer has spread to tissue just outside the thyroid and may have spread to lymph nodes. - In stage IVC, cancer has spread to other parts of the body, such as the lungs and bones, and may have spread to lymph nodes. How cancer of the thyroid is treated There are treatments for all patients with cancer of the thyroid. Four types of treatment are used: surgery (taking out the cancer) radiation therapy (using high-dose x-rays or other high-energy rays to kill cancer cells) hormone therapy (using hormones to stop cancer cells from growing) chemotherapy (using drugs to kill cancer cells) Surgery is the most common treatment of cancer of the thyroid. A doctor may remove the cancer using one of the following operations: Lobectomy removes only the side of the thyroid where the cancer is found. Lymph nodes in the area may be taken out (biopsied) to see if they contain cancer. Near-total thyroidectomy removes all of the thyroid except for a small part. Total thyroidectomy removes the entire thyroid. Lymph node dissection removes lymph nodes in the neck that contain cancer. Radiation therapy uses high-energy x-rays to kill cancer cells and shrink tumors. Radiation for cancer of the thyroid may come from a machine outside the body (external radiation therapy) or from drinking a liquid that contains radioactive iodine. Because the thyroid takes up iodine, the radioactive iodine collects in any thyroid tissue remaining in the body and kills the cancer cells. Hormone therapy uses hormones to stop cancer cells from growing. In treating cancer of the thyroid, hormones can be used to stop the body from making other hormones that might make cancer cells grow. Hormones are usually given as pills. Chemotherapy uses drugs to kill cancer cells. Chemotherapy may be taken by pill, or it may be put into the body by a needle in the vein or muscle. Chemotherapy is called a systemic treatment because the drug enters the bloodstream, travels through the body, and can kill cancer cells outside the thyroid. Treatment of cancer of the thyroid depends on the type and stage of the disease, and the patient's age and overall health. Standard treatment may be considered because of its effectiveness in patients in past studies, or participation in a clinical trial may be considered. Not all patients are cured with standard therapy and some standard treatments may have more side effects than are desired. For these reasons, clinical trials are designed to find better ways to treat cancer patients and are based on the most up-to-date information. Clinical trials are ongoing in many parts of the country for some patients with cancer of the thyroid. To learn more about clinical trials, call the Cancer Information Service at 1-800-4-CANCER (1-800-422-6237); TTY at 1-800-332-8615. STAGE I PAPILLARY THYROID CANCER Treatment may be one of the following: Surgery to remove one lobe of the thyroid (lobectomy), followed by hormone therapy. Radioactive iodine also may be given following surgery. Surgery to remove the thyroid (total thyroidectomy). STAGE I FOLLICULAR THYROID CANCER Treatment may be one of the following: Surgery to remove the thyroid (total thyroidectomy). Surgery to remove one lobe of the thyroid (lobectomy), followed by hormone therapy. Radioactive iodine also may be given following surgery. STAGE II PAPILLARY THYROID CANCER Treatment may be one of the following: Surgery to remove one lobe of the thyroid (lobectomy) and lymph nodes that contain cancer, followed by hormone therapy. Radioactive iodine also may be given following surgery. Surgery to remove the thyroid (total thyroidectomy). STAGE II FOLLICULAR THYROID CANCER Treatment may be one of the following: Surgery to remove the thyroid (total thyroidectomy). Surgery to remove one lobe of the thyroid (lobectomy) and lymph nodes that contain cancer, followed by hormone therapy. Radioactive iodine also may be given following surgery. STAGE III PAPILLARY THYROID CANCER Treatment may be one of the following: Surgery to remove the entire thyroid (total thyroidectomy) and lymph nodes where cancer has spread. Total thyroidectomy followed by radiation therapy with radioactive iodine or external beam radiation therapy. STAGE III FOLLICULAR THYROID CANCER Treatment may be one of the following: Surgery to remove the entire thyroid (total thyroidectomy) and lymph nodes or other tissues around the thyroid where the cancer has spread. Total thyroidectomy followed by radioactive iodine or external beam radiation therapy. STAGE IV PAPILLARY THYROID CANCER Treatment may be one of the following: Radioactive iodine. External beam radiation therapy. Hormone therapy. A clinical trial of chemotherapy. STAGE IV FOLLICULAR THYROID CANCER Treatment may be one of the following: Radioactive iodine. External beam radiation therapy. Hormone therapy. A clinical trial of chemotherapy. Treatment will probably be surgery to remove the entire thyroid (total thyroidectomy) unless the cancer has spread to other parts of the body. If lymph nodes in the neck contain cancer, the lymph nodes in the neck will be removed (lymph node dissection). If the cancer has spread to other parts of the body, chemotherapy may be given. Treatment may be one of the following: Surgery to remove the thyroid and the tissues around it. Because this cancer often spreads very quickly to other tissues, a doctor may have to take out part of the tube through which a person breathes. The doctor will then make an airway in the throat so the patient can breathe. This is called a tracheostomy. Total thyroidectomy to reduce symptoms if the disease remains in the area of the thyroid. External beam radiation therapy. Chemotherapy. Clinical trials studying new methods of treatment of thyroid cancer. The choice of treatment depends on the type of thyroid cancer the patient has, the kind of treatment the patient had before, and where the cancer comes back. Treatment may be one of the following: Surgery with or without radioactive iodine. External beam radiation therapy to relieve symptoms caused by the cancer. Chemotherapy. Radioactive iodine. Radiation therapy given during surgery. Clinical trials. Last updated: April 23, 2013
