Ameloblastoma
Leczenie
Ameloblastoma to rzadki, łagodny, ale miejscowo agresywny nowotwór zębopochodny, charakteryzujący się wysokim ryzykiem nawrotów i destrukcją okolicznych tkanek. Standardem leczenia jest radykalna resekcja chirurgiczna z marginesem 1-2 cm zdrowej tkanki kostnej, co znacząco redukuje ryzyko nawrotu do około 8% w ameloblastoma litego/wielotorbielowatego. W przypadku żuchwy wykonuje się segmentalną mandibulektomię z natychmiastową rekonstrukcją, a w szczęce resekcję en bloc z zachowaniem marginesu co najmniej 1 cm. Metody zachowawcze, takie jak wyłuszczenie, kiretaż czy marsupializacja, stosowane głównie u dzieci i w ameloblastoma jednootworowym, wiążą się z wyższym ryzykiem nawrotów (do 60-90%). W leczeniu nawrotów rekomendowana jest resekcja marginalna lub segmentalna z marginesem bezpieczeństwa co najmniej 1 cm poza granicami radiologicznymi, wraz z natychmiastową rekonstrukcją ubytku kostnego.
Leczenie Ameloblastoma: podejście terapeutyczne
Ameloblastoma jest rzadkim, łagodnym nowotworem pochodzenia zębopochodnego, charakteryzującym się miejscową agresywnością, wysokim ryzykiem nawrotu oraz zdolnością do niszczenia sąsiednich tkanek. Mimo że jest klasyfikowany jako guz łagodny, jego leczenie stanowi wyzwanie dla specjalistów z dziedziny chirurgii szczękowo-twarzowej, ze względu na skłonność do nawrotów oraz konieczność zapewnienia funkcjonalnej i estetycznie akceptowalnej rekonstrukcji powstałego ubytku.1
Leczenie chirurgiczne
Chirurgia pozostaje główną metodą leczenia ameloblastoma. Podejście chirurgiczne może być radykalne lub zachowawcze, w zależności od wielkości, lokalizacji, typu histologicznego guza oraz wieku pacjenta.23
Podejście radykalne
Radykalne leczenie chirurgiczne obejmuje resekcję segmentalną lub marginalną z szerokim marginesem zdrowej tkanki, co jest obecnie uznawane za metodę z wyboru w większości przypadków.4
- Standardowo zaleca się resekcję guza z marginesem 1-2 cm zdrowej tkanki kostnej, co znacząco zmniejsza ryzyko nawrotu56
- W przypadku żuchwy wykonuje się segmentalną mandibulektomię z usunięciem 1-2 cm zdrowej kości z natychmiastową rekonstrukcją7
- W przypadku szczęki stosuje się resekcję en bloc poprzez różne dostępy do środkowej części twarzy, z zachowaniem co najmniej 1 cm marginesu8
Wskaźnik nawrotów po leczeniu radykalnym jest znacznie niższy niż w przypadku metod zachowawczych. Badania wykazały, że wskaźnik nawrotów w przypadku ameloblastoma litego/wielotorbielowatego po leczeniu radykalnym wynosi około 8%, podczas gdy po leczeniu zachowawczym sięga 41%.9
Podejście zachowawcze
Metody zachowawcze obejmują wyłuszczenie, kiretaż, marsupializację oraz dekompresję. Techniki te wiążą się jednak z wyższym ryzykiem nawrotu, zwłaszcza w przypadku ameloblastoma litego/wielotorbielowatego.1011
- Wyłuszczenie i kiretaż mogą być stosowane w przypadku mniejszych zmian i ameloblastoma jednootworowego, często w połączeniu z metodami pomocniczymi12
- Osteotomia obwodowa, aplikacja roztworu Carnoya, krioterapia lub elektrokoagulacja mogą być stosowane jako metody uzupełniające w celu zmniejszenia ryzyka nawrotu1314
- Marsupializacja lub dekompresja mogą być stosowane jako terapia wstępna w celu zmniejszenia objętości guza przed ostatecznym leczeniem chirurgicznym1516
Wskaźnik nawrotów po leczeniu zachowawczym jest znacznie wyższy i może sięgać 60-90% w przypadku ameloblastoma litego.17 Jednak w przypadku ameloblastoma jednootworowego (unicystycznego) metody zachowawcze mogą być skuteczne, z niższym wskaźnikiem nawrotów.18
Szczególne przypadki leczenia
Leczenie ameloblastoma u dzieci
Leczenie ameloblastoma u dzieci stanowi szczególne wyzwanie ze względu na kontynuację wzrostu twarzy, odmienną fizjologię kości oraz obecność niewyrzniętych zębów.19
- W przypadku dzieci preferowane jest podejście zachowawcze, które uwzględnia potencjał wzrostowy20
- Dekompresja w połączeniu z kiretażem może być skuteczną metodą leczenia ameloblastoma u dzieci, szczególnie w przypadku zmian żuchwy2122
- Wyłuszczenie z osteotomią obwodową może być rozważane jako pierwsze leczenie, z rezerwacją bardziej agresywnej terapii w przypadku nawrotu23
Leczenie ameloblastoma nawrotowego
W przypadku nawrotu ameloblastoma, zalecane jest bardziej radykalne podejście:24
- Resekcja marginalna lub segmentalna z marginesami bezpieczeństwa jest najlepszą metodą leczenia nawrotów25
- Idealna metoda leczenia nawrotu obejmuje resekcję kości z marginesem bezpieczeństwa co najmniej 1 cm poza widocznymi radiologicznie granicami26
- Natychmiastowa rekonstrukcja ubytku kostnego z wykorzystaniem przeszczepów lub płatów wolnych, umieszczenie implantów dentystycznych i rehabilitacja z zastosowaniem protez wspartych na implantach mogą poprawić funkcję szczęki i harmonię twarzy pacjenta27
Rekonstrukcja po resekcji
Po usunięciu ameloblastoma, szczególnie po rozległej resekcji, konieczna jest rekonstrukcja ubytku w celu przywrócenia funkcji i estetyki.2829
- Natychmiastowa rekonstrukcja z wykorzystaniem wolnego transferu tkanek daje dobre wyniki estetyczne i funkcjonalne30
- Metody rekonstrukcji obejmują przeszczepy z grzebienia biodrowego, przeszczepy żebrowo-chrzęstne, mikrowaskularne płaty kostne oraz alloplastyczne protezy stawu skroniowo-żuchwowego31
- Zastosowanie technologii planowania wirtualnego umożliwia przewidywalną restaurację konturów żuchwy3233
- Rehabilitacja protetyczna z wykorzystaniem implantów dentystycznych może być przeprowadzona w drugim etapie w celu poprawy funkcji żucia34
Radioterapia w leczeniu ameloblastoma
Tradycyjnie uważano, że ameloblastoma jest oporny na radioterapię, jednak najnowsze badania wskazują, że może ona odgrywać rolę w leczeniu niektórych przypadków.35
Wskazania do radioterapii
Radioterapia może być rozważana w następujących sytuacjach:3637
- Jako leczenie uzupełniające po zabiegu chirurgicznym, szczególnie w przypadku dodatnich marginesów lub naciekania okołonerwowego38
- W przypadkach nieresekcyjnych lub gdy pacjent odmawia leczenia chirurgicznego3940
- W przypadku nawrotowych lub miejscowo zaawansowanych guzów41
W literaturze opisano przypadki skutecznego zastosowania radioterapii z modulacją intensywności dawki (IMRT), tomoterapii helikoidnej oraz radioterapii kierowanej obrazem (IGRT) w leczeniu ameloblastoma.42
Dawkowanie i techniki
W prezentowanych przypadkach zastosowano następujące schematy radioterapii:
- Radioterapia zewnętrzna techniką VMAT, fotony wysokoenergetyczne, w dawce 60 Gy, 2 Gy/frakcję, 5 frakcji/tydzień43
- Osiągnięto całkowitą remisję i brak nawrotu po roku obserwacji po leczeniu44
Radioterapia z modulacją intensywności jest istotnym postępem, który pozwala dostarczyć odpowiednią dawkę do guza przy jednoczesnym oszczędzaniu narządów krytycznych.45
Nowe metody terapii celowanej
Odkrycie mutacji genetycznych w ameloblastoma otworzyło nowe możliwości leczenia celowanego, szczególnie w zakresie szlaku MAPK.4647
Inhibitory szlaku MAPK
Najczęstszą mutacją występującą w ameloblastoma jest mutacja BRAF V600E, która może być celem dla istniejących leków:48
- Wemurafenib i dabrafenib – inhibitory mutacji BRAF49
- Trametynib – inhibitor MEK50
- Ponatynib i regorafenib – inhibitory mutacji FGFR251
Badania wykazały, że komórki ameloblastoma z mutacją BRAF V600E są wrażliwe na leczenie wemurafenibem in vitro, co sugeruje, że inhibicja mutanta BRAF może być korzystna w leczeniu ameloblastoma.52
Wyniki badań klinicznych
Pierwsze wyniki stosowania terapii celowanej w ameloblastoma są obiecujące:53
- Pacjenci leczeni dabrafenibem obserwowali zmniejszenie guza w ciągu kilku dni od rozpoczęcia leczenia54
- W przeglądzie systematycznym obejmującym 23 pacjentów z ameloblastoma leczonych terapią przeciw MAPK, większość pacjentów doświadczyła znacznego zmniejszenia guza, a działania niepożądane były generalnie łagodne55
- Terapia neoadjuwantowa z wykorzystaniem inhibitorów BRAF pozwoliła na zmniejszenie rozmiaru guza i przeprowadzenie mniej inwazyjnego zabiegu chirurgicznego56
W niektórych przypadkach zaobserwowano regenerację kości do stanu prawie identycznego jak przed chorobą, co wskazuje na potencjał terapii celowanej w leczeniu ameloblastoma.57
Potencjał terapii celowanej
Terapia celowana może mieć kilka zalet w leczeniu ameloblastoma:58
- Możliwość znacznego zmniejszenia chorobowości związanej z radykalną chirurgią59
- Zastosowanie jako terapia neoadjuwantowa w celu zmniejszenia rozmiaru guza przed operacją60
- Potencjalna opcja leczenia w przypadku ameloblastoma nawrotowego lub przerzutowego61
- Zachowanie narządów i regeneracja tkanek62
Aktualnie prowadzone są badania kliniczne oceniające skuteczność dabrafenibu i trametynibu u pacjentów z ameloblastoma i specyficzną mutacją w genie BRAF.63
Dalsze postępowanie i obserwacja
Ze względu na wysokie ryzyko nawrotu ameloblastoma, konieczne jest regularne i długoterminowe monitorowanie pacjentów po leczeniu.6465
Protokół obserwacji
- Regularne wizyty kontrolne powinny być kontynuowane przez całe życie66
- Ryzyko nawrotu jest największe w pierwszych trzech latach, ale może wystąpić znacznie później, nawet 15-30 lat po leczeniu67
- Odpowiednia okresowa obserwacja kliniczna i radiologiczna przez co najmniej dziesięć lat jest niezbędna68
- Nawroty mogą być trudne do leczenia, dlatego wczesne wykrycie jest kluczowe69
Zalecenia po leczeniu
Po zakończeniu leczenia ameloblastoma, pacjenci powinni przestrzegać następujących zaleceń:70
- Regularne wizyty kontrolne u lekarza w celu monitorowania procesu gojenia i wykrywania potencjalnych oznak nawrotu71
- Dbanie o dobrą higienę jamy ustnej poprzez regularne szczotkowanie zębów i nitkowanie72
- Zrównoważona dieta bogata w białka, owoce i warzywa może wspierać naturalne procesy gojenia i poprawiać ogólny stan zdrowia73
Podsumowanie leczenia ameloblastoma
Leczenie ameloblastoma wymaga indywidualnego podejścia, uwzględniającego wiele czynników, takich jak wiek pacjenta, lokalizacja i rozległość guza, typ histologiczny oraz ogólny stan zdrowia.74
Aktualnie resekcja chirurgiczna z szerokim marginesem zdrowej tkanki pozostaje złotym standardem leczenia, szczególnie w przypadku ameloblastoma litego/wielotorbielowatego. Metody zachowawcze mogą być rozważane w wybranych przypadkach, zwłaszcza u dzieci i w przypadku ameloblastoma jednootworowego.7576
Nowe metody leczenia, takie jak terapia celowana inhibitorami BRAF i MEK, otwierają obiecujące perspektywy, szczególnie w zakresie zmniejszenia chorobowości związanej z rozległymi resekcjami chirurgicznymi.77
Bez względu na wybraną metodę leczenia, kluczowe znaczenie ma długoterminowa, regularna obserwacja w celu wczesnego wykrycia i leczenia potencjalnych nawrotów.78

- #1 Ameloblastoma: Management and Outcomehttps://pmc.ncbi.nlm.nih.gov/articles/PMC6289562/
Ameloblastoma is a locally destructive tumor with a propensity for recurrence if not entirely excised. Management of ameloblastoma poses a challenge for all involved in the field of head and neck surgery because successful treatment requires not only adequate resection but also a functional and aesthetically acceptable reconstruction of the residual defect. […] Resection with wide margins and reconstruction in the same sitting is currently accepted as the treatment of choice in most cases. Idea of conservative surgery is no longer entertained since it is associated with higher recurrence rate. […] Segmental mandibulectomy with removal of 1-2 cm disease-free bone with immediate reconstruction is considered as an ideal treatment for ameloblastoma. This gives good cosmetic results and also addresses speech and eating problems. […] The management of ameloblastoma still poses a big challenge in spite of being the most common odontogenic tumor. In our study, we have found that segmental mandibulectomy with disease-free margin of around 1 cm and immediate reconstruction with free tissue transfer have shown good results.

Ameloblastoma treatment may depend on your tumor’s size and location, and the type and appearance of the cells involved. Treatment may include: […] Surgery to remove the tumor. Ameloblastoma treatment usually includes surgery to remove the tumor. Ameloblastoma often grows into the nearby jawbone, so surgeons may need to remove the affected part of the jawbone. An aggressive approach to surgery reduces the risk that ameloblastoma will come back. […] Radiation therapy. Radiation therapy using high-powered energy beams might be needed after surgery or if surgery isn’t an option. […] Due to the risk of recurrence after treatment, lifelong, regular follow-up appointments are important.
- #3 Ameloblastoma | Treatment & Management | Point of Carehttps://www.statpearls.com/point-of-care/17438
Mural and solid ameloblastomas are treated with complete surgical excision with normal bone margins at a minimum of five to fifteen mm, though ten mm margins are most common. Reported recurrence rates are up to 70%, with incomplete resection being the most common reason for the high recurrence rate. Enucleation and curettage, cryotherapy and marsupialization have all been used to treat ameloblastomas; however, these modalities are not curative and are not standard of care now. […] Ameloblastic carcinoma treatment is generally via surgical resection with 2 to 3 cm margins. Concurrent chemoradiotherapy is an option after resection for positive margins or perineural invasion. In malignant ameloblastoma, surgical resection with 1 to 2 cm margins is usually the treatment modality of choice, and no chemotherapy or radiotherapy is generally required.

Surgery is the most effective treatment. […] Early treatment and careful monitoring after treatment can prevent an ameloblastoma from damaging your jaw. […] Surgery that removes the tumor and some nearby tissue (enough to ensure no abnormal cells remain) is the best treatment for ameloblastoma. […] Most people with ameloblastomas need radical surgery. Your provider will remove the tumor and a large amount of bone and tissue to reduce the chance of your tumor growing back. […] If you’re not a candidate for surgery, your provider may recommend radiation therapy to get rid of the tumor. Or you may need radiation therapy after surgery to destroy any remaining tumor cells. […] Afterward, you may need additional treatments to get back to feeling like yourself again. […] Seeking treatment for an ameloblastoma can prevent these worst-case scenarios from happening. […] Ask your provider about the type of surgery they recommend based on your tumor type and health. They’re your best resource for explaining the best treatments available to get rid of the tumor while sparing as much healthy tissue in your jaw as possible.

- #9 The Effect of Conservative vs. Radical Treatment of Ameloblastoma on Recurrence Rate and Quality of Life: An Umbrella Reviewhttps://www.mdpi.com/2077-0383/13/17/5339
In Hendra et al. 2019, the pooled recurrence rate of solid/multicystic ameloblastomas following radical treatment was 8%, while conservative treatment caused recurrences in 41%. For unicystic ameloblastomas, these values were 3% and 21%, respectively. […] Similarly, Almeida et al. showed that the relative risk of recurrence was 3.15-fold greater when conservative treatment was performed on primary multicystic ameloblastoma in comparison to radical treatment. […] The primary finding of this umbrella review is that radical treatments for ameloblastoma are associated with significantly lower recurrence rates compared to conservative treatments. This suggests that radical approaches may offer better long-term disease control. […] For clinicians, this review underscores the importance of weighing the benefits of lower recurrence rates against the risks of adverse outcomes, including esthetic and functional impairments.

Ameloblastoma is a benign neoplasm essentially composed of epithelial tissue that has an invasive and infiltrative behavior at local level with a high recurrence rate. […] This way, this study is a literature review of works published between 2006 and 2014 conducted to find the existing protocols for the treatment of ameloblastomas. […] When proper diagnosis is carried out, it is crucial to establish a good treatment plan based on clinical and imaging examinations. […] There are several reports of various treatment methods for ameloblastomas, ranging from the most conservative to the most radical. Example are: curettage; cryotherapy; removal associated with cryotherapy; marsupialization; electrocauterization; sclerotherapy; and radiotherapy. […] One of the most reported techniques is complete surgical removal of the lesion, including the extension of a security margin with at least 1- to 2-cm thickness to reduce the risk of recurrence.

The disadvantages of radical methods are chewing problems, dysfunction of mandibular movements, and noticeable mutilation including facial deformity. […] Therefore, the present study was conducted in order to bring together the information of the literature about treatment options for ameloblastomas. […] An efficient clinical and imaging assessment is very important to determine the best treatment, given that unilocular cases are less aggressive. […] These cases have less chance of recurrence, thus allowing dental surgeons to perform a less invasive surgery. […] Often, surgeons choose the combination of conventional surgery and ancillary methods, such as the application of Carnoy’s solution, cryotherapy, or diathermy, in order to reduce the risk of lesion recurrence. […] A fundamental step to choose the best treatment for ameloblastomas is the identification of the type of lesion, namely: peripheral; unicystic; multicystic; and even solid and desmoplastic.

According to several authors, smaller and unicystic lesions can be treated with enucleation and curettage, which can also be associated with other ancillary procedures, such as peripheral osteotomy, application of Carnoy’s solution, and cryotherapy. […] Even with the purpose of avoiding recurrences of the lesion, it is possible to combine procedures such as cryotherapy or radiotherapy with the main intervention. […] After an extensive review of the literature on treatments of ameloblastomas, we concluded that: (a) the best treatment for ameloblastoma is still its total resection, given that recurrence rates are low when this technique is used; (b) even though total resection of the lesion is the most appropriate treatment, it can lead to irreversible sequelae; (c) conservative treatments, such as decompression and marsupialization, have been proposed in the literature to avoid sequelae, followed by radical surgical treatment.

Local treatment has an increased risk of recurrence, therefore it may be complemented with further application of Carnoy’s solution, cryotherapy or diathermy in order to reduce the recurrence rate. […] The purpose of this study was to analyze the therapeutic results obtained from a series of patients with mandibular ameloblastomas and to specifically focus attention on evaluating the surgical management of recurrent ameloblastoma. […] When detecting tumor recurrence, the ideal treatment method is bone resection with a safety margin of at least 1 cm beyond the radiographically visible margins. […] This may be performed by either marginal or segmental mandibulectomy depending on the location and extent of recurrence. […] Immediate reconstruction of the bone defect with free grafts or flaps, placement of dental implants and rehabilitation with implant-supported prostheses in a second stage can improve jaw function and facial harmony of the patient.

The management protocol proposed in 2010 recommends that unicystic ameloblastomas should initially be approached with marsupialization, followed by a careful radiological assessment to determine whether the lesion is decreasing. […] The authors propose that these resections should have a bone margin of at least 1.5 cm between the lesion and healthy tissue. […] The authors suggest that the treatment of solid/multicystic ameloblastomas should firstly consider the assessment of anatomical barriers, such as cortical bone, periosteum, muscles, and mucous membranes that might have been affected. […] In order to reduce the extent of the surgery performed to remove the lesion, and decrease the risk of recurrence, some techniques can be associated with the final resolutive procedure. […] Marsupialization is an example of a technique that has been used in some extensive ameloblastomas.

The treatment of UA has been controversial and can be radical or conservative. […] Conversely, conservative treatments comprise enucleation, enucleation followed by application of Carnoys solution, or marsupialization followed by enucleation. […] UAs biologic behavior is considered to be less invasive, and it responds more favorably to conservative treatment than a multicystic ameloblastoma. […] Therefore, conservative therapy was performed in our patient. We used marsupialization as an initial treatment of UA to minimize the tumors volume, and after they regressed in size, they were enucleated. […] The aim of marsupialization is to reduce the size of the tumor so that a less extensive surgery is required. […] The benefits of decompression are maintenance of pulp vitality, preservation of the inferior alveolar nerve or maxillary sinus, preservation of the mandibular contour and growth, prevention of fracture of the jaw, and low risk for recurrence.

Ameloblastoma is a common benign, locally aggressive odontogenic neoplasm that usually occurs in the vicinity of the mandibular molars or ramus. […] Although surgery is the mainstay of treatment, the extent of resection is controversial. The challenge in managing ameloblastoma is in achieving complete excision such that chances of recurrence is minimal and reconstruction of the defect when the tumour is large. […] Enucleation/curettage versus resection with broad margins has been the two treatment options for ameloblastomas that have generated controversy. With cautious enucleation, solid ameloblastomas have a high recurrence rate (6090%). […] The solid or multicystic-type ameloblastoma has so been given the preference for a segmental excision with a 1 to 2-cm margin. […] The main goals of mandibular reconstruction are to restore function and produce a satisfactory cosmetic result.
- #18 Treatment of recurrent mandibular ameloblastomahttps://www.spandidos-publications.com/10.3892/etm.2013.1165?text=fulltext
Ameloblastoma is a locally invasive benign odontogenic tumor with a high rate of recurrence in the long term. […] The therapeutic challenge is to achieve a complete lesion excision with the least possible morbidity. […] A number of different treatment strategies have been previously reported including local techniques (curettage, enucleation or marsupialization) or radical treatments (marginal or en-bloc segmental resection with safety margins and reconstruction of bone defect). […] Solid/multicystic ameloblastomas have been identified as the most aggressive subtype, with a high recurrence rate following local excision. […] By contrast, unicystic ameloblastomas are described to have a lower rate of recurrence and enucleation, with curettage potentially being sufficient for their management.

Ameloblastoma is a benign odontogenic tumour of epithelial origin that is slowly growing, locally aggressive, has a high recurrence rate but is uncommon in children. […] Treatment of ameloblastoma in children is complicated by three factors: (1) physiologic factors such as the continued facial growth, different bone physiology and the presence of unerupted teeth; (2) difficulty in the initial diagnosis and (3) predominance of the unicystic type of ameloblastoma. […] To present the outcome and advantage of a conservative treatment approach in the management of unicystic ameloblastoma in a paediatric patient. […] Enucleation with peripheral ostectomy seems a viable option in paediatric patients considering the amount of post-operative morbidity associated with aggressive management which can always be taken up a later stage if warranted.
- #20https://journals.lww.com/jodd/fulltext/2022/16020/management_of_paediatric_ameloblastoma.12.aspx
Treatment planning for ameloblastoma in a child must take into consideration the age of the patient, type and size of the lesion and reconstruction of the defect thereafter. […] This modified enucleation approach could perhaps be considered a treatment option in the management of large UCAs in paediatric patients, particularly in cases without cortical or periosteal breakthroughs. […] Published reports now recommend a relatively conservative treatment like enucleation with peripheral ostectomy in the first instance, reserving a more aggressive therapy for any recurrence considering the growth potential and capacity for bone regeneration in children.

Ameloblastoma (AM) is the most common benign odontogenic tumor, which is more often detected in the mandible than maxilla, especially the mandibular body and mandibular angle. […] Compared with the mainstream osteotomy and reconstructive surgery for adult ameloblastoma, there is more room for discussion in the treatment of pediatric ameloblastoma. […] We report two patients with ameloblastoma under 10 years old who are treated with curettage and fenestration, which is a beneficial method for children with ameloblastoma. […] Based on the principles of minimally invasive and functional preservation, we believe that curettage combined with decompression can be the first choice for treating AM in children, especially for mandibular lesions. […] Our previous retrospective study showed that the effective rate of fenestration decompression combined with secondary curettage(FDSC) in the treatment of multicystic ameloblastoma was 71.19%, and the effective rate in the treatment of unicystic ameloblastoma was 93.02%.

Given the high recurrence rate of curettage and the impact of osteotomy on growth, development, and psychology of children, we aim to use curettage combined with decompression in recent years to treat patients with classic AM who meet the indications, and satisfactory results have been achieved. […] The superiority of this approach was particularly evident in the treatment responses of the two patients aged under 10. […] We believe that decompression combined with curettage could be the first choice for treating AM in children, especially for mandibular lesions.

Treatment planning for ameloblastoma in a child must take into consideration the age of the patient, type and size of the lesion and reconstruction of the defect thereafter. […] This modified enucleation approach could perhaps be considered a treatment option in the management of large UCAs in paediatric patients, particularly in cases without cortical or periosteal breakthroughs. […] Published reports now recommend a relatively conservative treatment like enucleation with peripheral ostectomy in the first instance, reserving a more aggressive therapy for any recurrence considering the growth potential and capacity for bone regeneration in children.

Management of Recurrence of Ameloblastoma and Odontogenic Keratocyst: A Cross-Sectional Study […] The aim of this study was to investigate the clinicopathologic features of recurrent ameloblastoma and OKC cases, and evaluate outcomes of our treatments in terms of recurrence. […] We performed radical treatments in these cases (ten patients underwent marginal resections, and thirteen patients underwent segmental resection), and no recurrence was observed during the follow-up period. […] Marginal or segmental resection with safety margins is the best method to treat recurrences of OKC or ameloblastoma cases. […] Treatment modalities in the literature include decompression, marsupialization, curettage, enucleation, and more invasive methods, such as radical enucleation and resection.

- #30 Ameloblastoma: Management and Outcomehttps://pmc.ncbi.nlm.nih.gov/articles/PMC6289562/
Ameloblastoma is a locally destructive tumor with a propensity for recurrence if not entirely excised. Management of ameloblastoma poses a challenge for all involved in the field of head and neck surgery because successful treatment requires not only adequate resection but also a functional and aesthetically acceptable reconstruction of the residual defect. […] Resection with wide margins and reconstruction in the same sitting is currently accepted as the treatment of choice in most cases. Idea of conservative surgery is no longer entertained since it is associated with higher recurrence rate. […] Segmental mandibulectomy with removal of 1-2 cm disease-free bone with immediate reconstruction is considered as an ideal treatment for ameloblastoma. This gives good cosmetic results and also addresses speech and eating problems. […] The management of ameloblastoma still poses a big challenge in spite of being the most common odontogenic tumor. In our study, we have found that segmental mandibulectomy with disease-free margin of around 1 cm and immediate reconstruction with free tissue transfer have shown good results.

Mural and solid ameloblastomas are treated with complete surgical excision with normal bone margins at a minimum of five to fifteen mm, though ten mm margins are most common. Reported recurrence rates are up to 70%, with incomplete resection being the most common reason for the high recurrence rate. Enucleation and curettage, cryotherapy and marsupialization have all been used to treat ameloblastomas; however, these modalities are not curative and are not standard of care now. […] Ameloblastic carcinoma treatment is generally via surgical resection with 2 to 3 cm margins. Concurrent chemoradiotherapy is an option after resection for positive margins or perineural invasion. In malignant ameloblastoma, surgical resection with 1 to 2 cm margins is usually the treatment modality of choice, and no chemotherapy or radiotherapy is generally required.

Ameloblastoma grows slowly, is locally invasive, and has a high recurrence rate, especially if not adequately removed at initial surgery. Therefore, the treatment of choice is jaw resection, which often results in significant morbidity. […] The very high incidence of activating BRAF mutations and the additional recurrent, mutually exclusive mutations in the MAPK pathway genes KRAS, NRAS, and HRAS strongly implicate this pathway as the main driver of ameloblastoma growth. In addition, the recurrent mutations in the FGFR2 gene suggest the role of this RTK as a potent activator of the MAPK pathway in ameloblastoma. Various targeted therapies inhibiting the activity of the MAPK pathway are currently available. […] Intriguingly, ameloblastoma cells harboring the BRAF V600E mutation were shown to be sensitive to vemurafenib treatment in vitro, suggesting that mutant BRAF inhibition could be beneficial in ameloblastoma. Considering the importance of MAPK pathway activation for ameloblastoma, MAPK pathway inhibitors should be evaluated as novel targeted therapy for this disease.

Consideration was given to using the neo-adjuvant MAPK pathway inhibitor therapy, dabrafenib, to reduce the morbidity of the surgery by shrinking the size of the tumor and proceeding to a simple enucleation without injuring the alveolar nerve and the second molar. […] This study reported on 13 articles with 23 patients diagnosed with ameloblastoma or its variants and treated with targeted therapy focusing only on the MAPK pathway. BRAF V600E represents most of the mutated genes in that pathway for this review. […] The key benefit of neo-adjuvant molecular targeted therapies is that they can significantly reduce the surgical morbidity seen in radical surgery with either primary or recurrent ameloblastoma. This also emphasizes the necessity of systematic gene profiling for each tumor, allowing for the identification of potential targeted therapies with a multidisciplinary team. […] Anti-MAPK targeted therapy seems to be safe and efficient in treating ameloblastoma that is primary, recurrent, or metastasizing. It allows for a clinical, radiological, pathological, and symptom-relieving response for this rare but potentially devastating disease.

Researchers have identified the mutations underlying a rare, understudied type of jaw tumor called ameloblastoma, and have also found FDA-approved drugs that may help treat the tumors. […] The Food and Drug Administration has already approved drugs for other cancers caused by these mutations. Now, the paper’s authors are pursuing funding for a pilot study to use one of these drugs to treat ameloblastoma. […] Doctors diagnose about 300 to 600 cases of ameloblastoma in the United States each year. Neither drugs nor radiation have been successful at eradicating the cancer, leaving surgery as the only option. […] Perhaps most promising, researchers found that there are already FDA-approved drugs for cancers with mutations in the same developmental pathway. A drug called vemurafenib is toxic to ameloblastoma cell cultures that harbor a BRAF mutation, they found. […] In April, West and McClary began collaborating with Dimitrios Colevas, MD, associate professor of oncology at Stanford, to plan a small pilot study to assess whether vemurafenib can shrink ameloblastoma tumors that have a BRAF mutation.

- #55 Anti-MAPK Targeted Therapy for Ameloblastoma: Case Report with a Systematic Reviewhttps://www.mdpi.com/2072-6694/16/12/2174
Ameloblastoma is a type of tumor that usually forms in the jaw; while typically benign, it grows aggressively and often recurs after treatment. Traditional treatment involves extensive surgery, which can significantly affect a patientâs quality of life. Recent research has focused on a new approach, targeting a specific cellular pathway known as the MAPK pathway, which appears to be involved in the development of these tumors. In this study, we reviewed the outcomes of 23 patients treated with this targeted therapy to assess its safety and effectiveness. The results were promising: most patients experienced significant tumor reduction, and the side effects were generally mild. This suggests that MAPK pathway inhibitors could be a viable alternative to surgery, potentially offering improved outcomes for patients with ameloblastoma, minimizing surgical risks, and preserving quality of life. This advancement could greatly impact the approach to treating this challenging condition.

Consideration was given to using the neo-adjuvant MAPK pathway inhibitor therapy, dabrafenib, to reduce the morbidity of the surgery by shrinking the size of the tumor and proceeding to a simple enucleation without injuring the alveolar nerve and the second molar. […] This study reported on 13 articles with 23 patients diagnosed with ameloblastoma or its variants and treated with targeted therapy focusing only on the MAPK pathway. BRAF V600E represents most of the mutated genes in that pathway for this review. […] The key benefit of neo-adjuvant molecular targeted therapies is that they can significantly reduce the surgical morbidity seen in radical surgery with either primary or recurrent ameloblastoma. This also emphasizes the necessity of systematic gene profiling for each tumor, allowing for the identification of potential targeted therapies with a multidisciplinary team. […] Anti-MAPK targeted therapy seems to be safe and efficient in treating ameloblastoma that is primary, recurrent, or metastasizing. It allows for a clinical, radiological, pathological, and symptom-relieving response for this rare but potentially devastating disease.
