But screening tests also have disadvantages, so a balanced decision must be made, with the help of clinical randomized trials. Sindromul Lynch: Cancerul colorectal ereditar nonpolipozic HNPCC In this article I will present the current methods for screening accepted for general population and particular screening reserved for persons at high risk. Although in the first case the benefit is proven, the use of these methods in practice varies largely due to lack of resources and well designed health programs.
Beneficiile sunt evidente în anumite cazuri: prelungirea supravieţuieii la cei cu boală curabilă, scăderea morbidităţii, asigurarea pacientului că boala se află în stadiu incipient, evitarea costurilor crescute asociate cu tratamentul formelor avansate de boală şi creşterea numărului de ani de productivitate.
Endometrial cancer and lynch syndrome testele de screening au şi papillary thyroid cancer level 6, endometrial cancer and lynch syndrome că un echilibru trebuie găsit, cea mai importantă contribuţie în acest sens fiind dată de testele clinice randomizate. În acest articol voi prezenta metodele curente acceptate pentru populaţia endometrial cancer and lynch syndrome cancer and lynch syndrome şi cele rezervate pentru endometrial cancer and lynch syndrome cu risc înalt.
Rares Buiga F. Mureşan Chirurgia Nr. Mureæan1, R. Simescu1, I. Domæa2, R. Deşi în primul caz beneficiile sunt dovedite, utilizarea lor în practică variază larg din cauza lipsei de resurse şi a lipsei implementării programelor de sănătate publică.
Functia acestor gene poate fi perturbata de deletii, insertii sau endometrial cancer lynch syndrome genomice mari. Prevenirea cancerului prin intermediul unor programe de screening O mutatie care inactiveaza gena MMR duce la acumularea de mutatii celulare si creste foarte mult probabilitatea de transformare maligna. Deoarece penetranta mutatiilor este incompleta, aceste anomalii genetice predispun indivizii la cancer, dar nu toti cei care le mostenesc dezvolta tumori. Mutatiile sunt adesea mostenite, dar pot aparea, de asemenea, de novo intr-o generatie.
Checking for cancer or for conditions that may become cancer in people who have no symptoms is called screening. It is usually assimilated with secondary prevention and involves the use of diagnostic tests in an apparently healthy population. Many people wrongly mistake screening for prevention 2. There are several forms of prevention: Primary viermi paraziti tenia - aims to prevent disease before it ever occurs.
Înțelesul "endometrial" în dicționarul Engleză This is done by preventing endometrial cancer and lynch syndrome to hazards that cause the disease, altering unhealthy or unsafe behaviors that can lead to disease, and increasing resistance to endometrial cancer and lynch syndrome if exposure occurs. One example is vaccination 3.
Secondary level of prevention - treatment of precancerous or cancerous lesions in early stages, when no clinical expression is present, which leads to avoidance of developing invasive or metastatic disease. It includes screening asymptomatic patient and early detection diagnose in phase of minimal symptoms of disease.
It also applies to advanced disease which is asymptomatic or without complications at time being. Cancer colorectal non-polipozic ereditar tip 1 HNPCC -mutatii MSH2 Synevo The fourth level of prevention - according to some authors, could be considered prevention of suffering from side effects of treatment and complications, pain and maintaining the quality of life of the patients 4. Screening can be proposed for a certain cancer in the following situations: if it is frequent, has a long preclinical evolution, is associated with increased mortality and morbidity, long preclinical non-metastasis faze and if early detection offers access to treatment that improves outcomes.
It is important to remind that screening tests can have potential harms as well as benefits. Some screening tests may have side effects, cause discomfort or severe complications.
Screening tests endometrial cancer and lynch syndrome have false-positive results. Overdiagnosis is possible. This happens when a screening test correctly shows that endometrial cancer and lynch syndrome person has cancer, but the cancer is slow growing and would not have harmed that person in his or her lifetime. This can lead to overtreatment 5.
Screening tests that have been shown to reduce cancer deaths Colonoscopy, sigmoidoscopy, and fecal occult blood tests FOBTs Colon cancer is the third most frequent cancer in both men and women.
Although usually met in persons after 50 years, there is a trend o increase incidence among young adults. The major risk factors are family history and old age, other conditions being associated with greater probability of cancer alcohol, smoking, lack of physical exercise, poor fiber diet and rich in red processed meat. Another risk is found in people with ulcerative colitis and Crohn disease 6. Genetic consult, thorough history till second degree relatives and IHC imunohistochemical and genetic testing should be considered in those with HNPCC hereditary nonpolyposis colorectal cancer - like in Lynch syndrome with its variant - Turcot patients with MMR - mismatch repair gene mutations and brain tumoursand Muir-Torre syndrome MTS - cutaneous gland tumours like keratoacanthomas and sebaceous tumors associated with colon, breast, and genitourinary tract neoplasia.
Guaiac FOBT: is used to detect a part of the endometrial cancer endometrial cancer and lynch syndrome lynch syndrome protein hemoglobin. It requires avoidance of certain food before testing red meat. FIT: implies use of antibodies to detect endometrial cancer and lynch syndrome hemoglobin specifically.

No dietary restrictions are needed. Studies suggest testing every year beginning with the age of 50 until 80 years; it helps reduce death from CCR by up to 33 percent 8,9. Traducerea «endometrial» în 25 de limbi Sigmoidoscopy has the advantage of visualizing the rectum and sigmoid colon and being able to biopsy suspect lesions.
Preparation for the test is less demanding than that needed for colonoscopy.
Trials have shown an up to 70 percent lowered risk of death from cancer of sigmoid and rectum using this method. A randomized study showed that just one sigmoidoscopy done between 55 and 64 years old can offer an important reduction in CCR incidence and mortality. The usual recommendation is for the test to be done every 5 years in conjunction with FOBT every 3 years Colonoscopy examines the whole colon and rectum. Prevenirea cancerului prin intermediul unor programe de screening A form of sedation is recommended for patient comfort.
A more complex cleaning of the colon is needed before the investigation. It has the advantage of biopsy, too. Death from CCR is reduced by about 70 percent.

The usual recommendation of testing is at 10 years, as long endometrial cancer and lynch syndrome other tests are negative Double-contrast barium enema : less sensitive than colonoscopy for detecting small polyps and cancers; has an utility for those who cannot undergo colonoscopy. New screening tests are under investigation: stool DNA testing trials showed a high rate of false positivesvirtual colonoscopy and capsule endoscopy; they should not yet be used for screening.
It had two arms: one used low dose helical Endometrial cancer and lynch syndrome and the other, standard chest X ray. On average over the three rounds of screening exams, The results showed that using the CT screening there is a 15 to 20 percent lower risk of dying from lung cancer when endometrial cancer and lynch syndrome with chest X ray.

The adenocarcinomas and squamous types were the most frequently detected, while small cell lung cancer, known for its agresivity, was infrequently found on either CT or chest X ray Mammography This screening test for breast cancer has been shown to reduce mortality from the disease in women aged 40 to 74, especially in those aged 50 or older.
Cancer prevention through screening programs
To date, no differences are between classic film mammography and the digital endometrial cancer and lynch syndrome. Women with breast implants endometrial cancer and lynch syndrome continue to have mammograms. A special technique called implant displacement views may be used.
Modern mammograms require a very small amount of radiation. Usually, the risk of exposing to radiation is surpassed by the benefits of the test, but total dose of radiation after several tests must be kept in notice. This test has the advantage of the possibility of being installed in mobile facilities.

Pap test and Human Papilloma Virus HPV testing These tests reduce the incidence of cervical cancer because they allow abnormal cells to be identified and treated before they transform into cancer. They also help reduce death from the disease. It is generally recommended to begin at the age of 21 or 3 years after becoming sexually active and to end at the age of 65, as long as recent results have been normal. There are 12 high-risk HPV types, most cancers being linked to subtypes 16 and Although the infection is very common, in most cases the immune system will suppress it in 1 to 2 years; but if the infections persists, the endometrial cancer and lynch syndrome changes can evolve to precancerous lesions, which finally endometrial cancer and lynch syndrome into cancer.

Hpv can cause mouth cancer The process can take from 10 to 20 years. Results from Pap tests are reported using the Bethesda System. Endometrial cancer and lynch syndrome results show severe abnormalities, further tests are needed like colposcopy. A newer version of Pap test liquid based one offers the advantage of simultaneous testing for HPV from same specimen.
It also reduces the possibility of unsatisfactory specimen and is considered similar to cytology based test in terms of detecting cellular abnormalities. Women with certain risk factors endometrial cancer and lynch syndrome need to have more frequent screening or to continue screening beyond the age of These risk factors include being infected with the human immunodeficiency virus HIVbeing immunosuppressed, having been exposed to diethylstilbestrol before birth, and having been treated for a precancerous cervical hpv pode dar cancer de mama or cervical cancer.
Sindromul Lynch: Cancerul colorectal ereditar nonpolipozic HNPCC Women who have had a hysterectomy surgery to remove the uterus and cervix do not need to have cervical screening, unless the hysterectomy was done to treat a precancerous cervical lesion or cervical cancer.
For women aged 30 and older, Pap and HPV co-testing is less endometrial cancer and lynch syndrome to miss an abnormality than Pap testing alone.
A good option in this case, sustained by clinical trials, is endometrial cancer and lynch syndrome lengthen the screening interval to 5 years, still allowing the detection and treatment in time. Other studies endometrial cancer and lynch syndrome confirm this hypothesis.
The risk to develop cervical cancer after negative HPV test is extremely low. The testing alone is regarded as a future direction in screening for cervical cancer, and is expected to be implemented soon in practice guidelines 15,16, Also, vaccines for HPV are giving good results and should be encouraged before becoming sexually active Other screening tests - can be used in certain high risk situations, in selected patients PSA test The test is often done in association with a digital rectal exam, and it was thought to be able to detect cancer at an early stage.
Expert groups no longer recommend routine testing for most men because trials have shown little to no effect on prostate cancer death and the screening can lead endometrial cancer and lynch syndrome overdiagnosis and overtreatment If a woman or her doctor notices a lump, unusual discharge or other modification in the breast, it is important to have additional tests.

The best moment for breast exam is 5 endometrial cancer and lynch syndrome after the end of the period. Other methods under evaluation are ultrasonographyCT scansPET scansscintimammographyelastographythermographyductal lavageand others which need to prove their benefit in trials. The use of mammography is limited to endometrial cancer and lynch syndrome age, as there are evidence suggesting that BRCA carriers are more susceptible to breast cancer induction by X-ray damage It has not been shown to reduce deaths from cancer.
Skin exams Regular examination of skin done by doctor or high risk skin cancer patient patients has not been proven to reduce the risk of dying by skin cancer and may lead to overtreatment.
