Se recomand utilizarea ecografiei tiroidiene asociat cu examenul citologic prin biopsie-aspiraie cu ac fin CBAF ca tehnic diagnostic de linia nti pentru identificarea i caracterizarea bolii tiroidiene nodulare I, A n cazul unei prelevri necorespunztoare, se recomand repetarea CBAF, iar n cazul neoplaziei foliculare, cu niveluri normale de hormon stimulator tiroidian TSH i aspect rece la scintigrafia tiroidian, se poate lua n considerare intervenia chirurgical IV, B Msurarea nivelurilor serice de calcitonin CT reprezint o metod fiabil de stabilire a diagnosticului de cancer tiroidian medular i trebuie s fac parte din evaluarea diagnostic a nodulilor tiroidieni IV, B.
Tratamentul iniial al CTD const n tiroidectomie total sau subtotal dac diagnosticul a fost stabilit nainte de intervenia chirurgical.
Pot fi acceptate i intervenii chirurgicale mai limitate n cazul CTD monofocal diagnosticat prin examen histologic la finalul operaiei efectuate pentru afeciuni tiroidiene benigne, dac tumora este mic, intratiroidian i are un tip histologic favorabil papilar clasic sau varianta folicular a cancerului papilar sau folicular minim-invaziv I, A.
Intervenia chirurgical este urmat de regul de administrarea I pentru ablaia tuturor esuturilor tiroidiene restante i a unei posibile tumori microscopice reziduale. Ablaia cu iod radioactiv este indicat la pacienii cu risc nalt IV, Bdar nu este recomandat la pacienii cu risc redus IV, D.
La pacienii cu risc intermediar decizia trebuie s fie individualizat. Dup tratamentul chirurgical, se recomand iniierea terapiei cu hormoni tiroidieni pentru substituia secreiei hormonale terapie de substituie i pentru inhibarea TSH, care poate fi un stimul de cretere al celulelor tumorale terapie de supresie.
La luni de la tratamentul iniial, se recomand evaluarea testelor funciei tiroidiene FT3, FT4, TSH pentru a se verifica caracterul adecvat al terapiei supresoare cu LT4, urmat la luni de o etap de screening care const ntr-un examen clinic, o ecografie cervical, determinarea nivelurilor serice ale Tg bazale i dup stimularea cu rhTSH, nsoite sau nu de WBS n scop diagnostic I, A Monitorizarea ulterioar a pacienilor care au fost considerai a fi liberi de boal la momentul primei evaluri de urmrire va consta n examinri clinice, papillary thyroid cancer fdg pet ale nivelurilor serice bazale ale Tg n timpul terapiei cu LT4 i ecografie cervical, efectuate anual.
Tratamentul bolii locoregionale recidivate are la baz asocierea dintre intervenia chirurgical i terapia cu iod radioactiv, suplimentate cu radioterapie extern dac nu este posibil excizia chirurgical complet sau dac tumora nu capteaz semnificativ iodul radioactiv IV, B. Metastazele la distan au anse mai mari de vindecare n cazul n care capteaz iod radioactiv i dac au dimensiuni reduse i localizare pulmonar; n caz contrar, sunt posibile numai tratamentul paliativ i prelungirea supravieuirii.
Chimioterapia nu este indicat i trebuie s fie ncurajat participarea la studii clinice IV, B. Pentru pacienii cu CTM fr semne papillary thyroid cancer fdg pet metastaze ganglionare la examenul clinic i papillary thyroid cancer fdg pet cervical, tratamentul const n tiroidectomie total indiferent dac CTM este sporadic sau ereditar, asociat cu disecie profilactic bilateral a ganglionilor limfatici centrali IV, B.
Management and Follow-up of High Risk Patients with Papillary Thyroid Cancer
Cel mai bine este ca disecia cervical lateral s fie rezervat pentru pacienii cu examinri imagistice preoperatorii pozitive IV, B. Dup tiroidectomia total, se va administra tratament de substituie cu tiroxin pentru meninerea concentraiilor serice ale TSH ntre limitele normale IV, B. Intervenia chirurgical este tratamentul principal al recidivelor locale i regionale, dac este posibil IV, B.

CTSD include tipuri histologice tumorale agresive, cum sunt subtipurile trabecular, insular i solid. Tratamentul iniial este reprezentat de tiroidectomia total. Pacienii cu boal nerezecabil sau cu boal locoregional persistent dup intervenia chirurgical pot fi tratai prin radioterapie extern V, C.
Administrarea chimioterapiei, cu agent unic sau n regimuri combinate, de exemplu cu cisplatin i doxorubicin, poate oferi doar rspunsuri pasagere i incomplete V, C. Dac este posibil, pacienii cu CTSD trebuie s fie inclui n studii clinice de evaluare a unor terapii noi Tabelul 4. Cancerul tiroidian anaplazic CTA este cea mai agresiv tumor tiroidian i unul dintre cele mai agresive cancere umane. Carcinomul tiroidian anaplazic afecteaz mai frecvent femeile, dar raportul dintre sexul feminin:masculin este de aproximativmai mic dect cel calculat pentru tipurile histologice papilar sau folicular.

Aceast tumor i are originea n celulele foliculare ale glandei tiroide, dar nu pstreaz niciuna dintre caracteristicile biologice ale celulelor originale, de exemplu captarea iodului sau sinteza Tg. CTA poate aprea de novo, dar n majoritatea cazurilor se dezvolt dintr-o tumor tiroidian preexistent bine difereniat, dup producerea unor mutaii suplimentare, n special mutaia p53 papillary thyroid cancer fdg pet.

Diagnostic Diagnosticul se stabilete de obicei cu uurin, pe baza aspectelor clinice tipice: mas de mari dimensiuni, dur, care invadeaz regiunea cervical i determin simptome compresive dispnee, tuse, paralizia corzilor vocale, disfagie i rgueal. Din cauza comportamentului agresiv al CTA, cel mai recent manual de stadializare a cancerului elaborat de American Joint Committee a clasificat toate CTA n categoria tumorilor Papillary thyroid cancer fdg pet define papilloma colli stadiu IV, indiferent de dimensiunile lor i de extensia tumoral total [11].
Tratament Tratamentul CTA nu a fost standardizat i, din pcate, nu exist nc un tratament eficace: intervenia chirurgical, chimioterapia, radioterapia utilizat singur sau n combinaie, nu amelioreaz supravieuirea.
Intervenia chirurgical este recomandat pentru controlul local al leziunilor rezecabile. Agentul citotoxic utilizat cel mai frecvent mpotriva carcinoamelor anaplazice este doxorubicina n monoterapie sau n combinaie cu cisplatina. Rezultatele au fost dezamgitoare. Adugarea bleomicinei sau a altor ageni nu a crescut eficacitatea acestei combinaii. Recent, paclitaxel a fost utilizat ntr-un studiu clinic i a determinat unele mbuntiri ale ratelor de rspuns, dar nu i ale supravieuirii.
Sunt necesare strategii terapeutice inovatoare; de papillary thyroid cancer fdg pet, warts on tongue images n curs de studiere strategii noi, cum sunt terapia intit de exemplu cu axitinib i sorafenibagenii de perturbare a funciei vasculare de exemplu combrestatin-A4 fosfat, anticorpi monoclonali mpotriva VEGF, de exemplu bevacizumab, cetuximabterapia de supresie genic tumoral i ageni de sistare a ciclului celular [40].
Pn n prezent, niciunul dintre aceti ageni nu a avut rezultate bune n tratamentul CTA; de aceea, sunt necesare cercetri noi pentru a contracara agresivitatea acestei tumori [30]. Conflict de interese Toi autorii au raportat lipsa unor conflicte poteniale de interese.
