Osteonecrose dos maxilares associada ao uso de bisfosfonatos: importante complicação do tratamento oncológico

Abstract: Os bisfosfonatos são um grupo de medicamentos utilizados no tratamento de doenças malignas metastáticas e em outras doenças ósseas como osteoporose e doença IntroduçãoOs pacientes com câncer e portadores de doenças metastáticas ósseas frequentemente exibem complicações que incluem dor, fratura patológica, compressão da medula espinhal e hipercalcemia, que causam piora da qualidade de vida, grande morbidade e mortalidade. 1 Essas alterações são normalmente consequência do processo de metástase, que é resultado … Show more

“…These alterations are usually a consequence of the metastatic process that result from osteoclast activation mediated by different cytokines produced by the tumor cells, which causes bone resorption and allows tumor growth. 7 In order to control these complications, in the last years, oncologists have used medications named bisphosphonates, which are non-metabolized pyrophosphate analogs capable of depositing in the bone and inhibiting osteoclastic function. These drugs are part of the treatment protocol for patients with moderate to severe hypercalcemia associated with cancer; osteolytic lesions associated with breast cancer and multiple myeloma together with antineoplastic chemotherapy; and osteolytic lesions originating from any solid tumor.…”

“…These indications have led to a massive use of bisphosphonates in most clinics and medical oncology hospitals world wide. 7 There are several types of bisphosphonates approved for clinical use. They are divided into generations and their antiresorptive properties increase approximately tenfold between generations of the drug.…”

“…Nas metástases ósseas do câncer de mama, os bisfosfonatos reduzem a dor, a incidência de novas metástases, a ocorrência de fraturas patológicas e o risco de hipercalcemia. Como efeito colateral do uso dos bisfosfonatos tem-se a ocorrência de necrose dos ossos da arcada dentária, que está relacionada ao fato dessas estruturas estarem em contato direto com a flora da cavidade bucal, favorecendo assim, a instalação de quadros infecciosos oportunistas [22][23][24] . O tratamento oncoterápico basicamente é dividido em cirurgia, quimioterapia e radioterapia 22 .…”
