Hipercalcemia Associada ao Câncer: Casos Clínicos (Cancer Associated Hypercalcemia: Clinical Cases)
– A hipercalcemia associada à malignidade é descrita em 10 a 20% dos pacientes com câncer em alguma etapa da doença, e significa mau prognóstico.
– A hipercalcemia é mais comum no carcinoma de células escamosas de pulmão, cabeça e pescoço, carcinoma de células renais, câncer de mama, mieloma múltiplo e linfoma
– A hipercalcemia associada ao câncer é, com frequência, devida à produção tumoral de peptídeos relacionados ao paratormônio (PTHrp), que se liga a receptores de PTH/PTHrp e estimula a reabsorção óssea e inibe a excreção renal de cálcio.
– Os sintomas relacionados ao sistema nervoso central predominam, tais como progressivo declínio da capacidade cognitiva, estupor e coma.
– As alterações na função renal (incapacidade de concentrar a urina acarretando poliúria) e no trato gastrointestinal (anorexia, náuseas e vômitos) corroboram para a desidratação e agravam a hipercalcemia.
– A hipercalcemia causada pelo câncer é comumente classificada em: 1) hipercalcemia osteolítica local, decorrente da intensa reabsorção óssea osteoclástica nas áreas em torno das células malignas na medula óssea; 2) hipercalcemia humoral maligna, causada pela secreção do peptídeo relacionado ao paratormônio (PTHrP) pela neoplasia maligna; 3) hiperparatireoidismo ectópico; 4) produção de 1,25 (OH)2 D pelo tumor.
O controle adequado da hipercalcemia é necessário para dar tempo de o paciente responder ao tratamento antineoplásico.
