Objetivos

El objetivo de este estudio es conocer las características de nuestros pacientes acromegálicos y evaluar los resultados de la aplicación de los protocolos de tratamiento habituales.

Pacientes y métodos

Se incluyó a todos los pacientes registrados con el diagnóstico de acromegalia (n=42). Se recogieron datos demográficos, estudio hormonal, función visual y pruebas de imagen al diagnóstico y durante el seguimiento, y tratamientos recibidos.

Resultados

En el 71,4% de los casos la acromegalia se debía a un macroadenoma hipofisario. El 63,2% del total de los pacientes fue sometido a tratamiento quirúrgico y el 36,8% recibió tratamiento radioterápico; 35 pacientes están recibiendo tratamiento médico, 11 de ellos como terapia primaria. Aplicando los criterios actuales, la cirugía no ha curado la acromegalia a ninguno de nuestros pacientes. Considerando concentraciones de factor de crecimiento similar a la insulina tipo 1 (IGF-1) normales para la edad y el sexo como criterio de control de la enfermedad, el tratamiento quirúrgico ha controlado la enfermedad en el 8,3% de los pacientes operados, mientras que la terapia médica ha controlado la enfermedad en el 71,4% de los pacientes (p<0,05). De los pacientes en tratamiento médico como terapia primaria, en el 45,5% el tumor ha disminuido de tamaño y en el resto no se han producido cambios significativos durante el seguimiento.

Conclusiones

A diferencia de lo que ocurre con el tratamiento médico, con el tratamiento quirúrgico no en todos los centros se consiguen los resultados publicados en la literatura médica. Al menos en algunos hospitales quizá debería optarse por el tratamiento médico primario de la acromegalia, si el paciente no presenta afectación visual.

Objective

To determine the characteristics of our acromegalic patients and to evaluate the results of applying the usual treatment schedules.

Patients and methods

All acromegalic patients were included (n=42). Demographic and hormonal data, visual function and imaging tests at diagnosis and during follow-up, as well as treatment, were recorded.

Results

Acromegaly was due to a pituitary macroadenoma in 71.4% of the patients. Surgery was performed in 63.2% of all the patients and radiotherapy was used in 36.8%. Medical treatment is being provided in 35 patients and is the primary therapeutic approach in 11 of these. With the currently used criteria, none of the patients has been cured by surgery. Considering age and sex-matched normal concentrations of insulin-like growth factor-1 (IGF-1) as a criteria of disease control, surgery has resulted in disease control in 8.3% of operated patients, while medical treatment has controlled the disease in 71.4% of patients (P<0.05). Of the patients receiving medical treatment as the primary therapeutic approach, tumoral size has decreased in 45.5%, while no significant change in tumoral size has been observed in the remaining patients.

Conclusions

In contrast with medical treatment, when surgery is used, not all centres obtain the results reported in the literature. At least in some hospitals, opting for primary medical treatment might be reasonable in patients without visual disturbances.
