ABSTRACT

Objectives:

ALP and LDH are serum markers of prognostic importance in prostate cancer patients. PET/CT imaging with Ga-68 PSMA has played an important role in prostate cancer imaging in recent years. Our aim in this study was to evaluate the relationship and prognostic significance between SUVmax values obtained with Ga-68 PSMA PET/CT and LDH and ALP levels in prostate cancer patients.

Methods:

We retrospectively evaluated 61 prostate cancer patients who had Ga-68 PSMA PET/CT imaging and who did not have a prostatectomy between 2019 and 2020. PSA, ALP and LDH levels were measured in all patients before or after imaging within a maximum of 28 days.

Results:

The median age of the patients included in this study was 73 (range 57–89) and all 61 patients were prostatic adenocarcinoma. 50 (82%) of the patients had distant metastasis in Ga-68 PSMA PET/CT. There was a significant positive correlation between serum LDH and PSA levels. There was a positive correlation between serum ALP and PSA levels. A negative correlation was found between ALP levels and prostate SUVmax.

Conclusions:

While negative correlation was found between SUVmax and ALP levels, no correlation was found between LDH levels and SUVmax. High ALP levels were found to be related to metastasis rates and severity and high serum PSA levels (AU)
RESUMEN

Objetivos:

ALP y LDH son marcadores séricos deimportancia pronóstica en pacientes con cáncer de próstata.Las imágenes de PET/CT con Ga-68 PSMA han jugado unpapel importante en las imágenes de cáncer de próstata enlos últimos años. Nuestro objetivo en este estudio fue evaluar la relación y la importancia pronóstica entre los valores de SUVmax obtenidos con Ga-68 PSMA PET/CT ylos niveles de LDH y ALP en pacientes con cáncer de próstata.

Métodos:

Evaluamos retrospectivamente a 61 pacientes con cáncer de próstata que se sometieron a imágenes de PET/CT con Ga-68 PSMA y que no se sometierona prostatectomía entre 2019 y 2020. Los niveles de PSA,ALP y LDH se midieron en todos los pacientes antes o después de la obtención de imágenes en un plazo máximo de28 días.

Resultados:

La mediana de edad de los pacientes incluidos en este estudio fue de 73 (rango 57–89) y los 61pacientes eran adenocarcinoma de próstata. 50 (82%) delos pacientes tenían metástasis a distancia en Ga-68 PSMAPET/CT. Hubo una correlación positiva significativa entrelos niveles séricos de LDH y PSA. Hubo una correlaciónpositiva entre los niveles séricos de ALP y PSA. Se encontró una correlación negativa entre los niveles de ALP y elSUVmáx prostático.

Conclusiones:

Si bien se encontró una correlaciónnegativa entre los niveles de SUVmáx y ALP, no se encontró correlación entre los niveles de LDH y el SUVmáx. Seencontró que los niveles altos de ALP estaban relacionadoscon las tasas de metástasis y la gravedad y los niveles altosde PSA en suero. (AU)
