The Influence of the Intraductal Carcinoma of the Prostate on the Short-Term Oncological Outcomes

Arch Esp Urol. 2022 Jun;75(5):405-409. doi: 10.37554/en-j.arch.esp.urol-20210522-3503-23.


AIM: The presence of intraductal carcinoma of the prostate (IDC-P) in radical prostatectomy (RP) specimens correlates with adverse prognostic factors such as worse biochemical recurrence-free survival, higher grade and stage disease. This study aimed to investigate the effect of IDC-P in radical prostatectomy specimens on short-term oncological outcomes.

MATERIALS AND METHODS: Patients who underwent RP at our clinic for prostate cancer between May 2016 and November 2019 were included in the study. They were divided into two groups based on the presence of IDC-P in RP specimens. Their clinical, pathological, and oncologic data were evaluated retrospectively.

RESULTS: A total of 98 patients underwent RP with a mean age of 65.5 years (50-83) and a mean follow-up time of 31.2 months (6-52). Seventy and 28 patients were evaluated in the group without IDC-P and group with IDC-P, respectively. Surgical margin positivity (p=0.307) and lymph node metastasis (p=0.017) rates were higher in the group with IDC-P. Although there were no statistical differences between the groups, at follow-up biochemical recurrence rate (p=0.052) was higher, and mean time to biochemical recurrence rates were lower (p=0.057) in the group with IDC-P. The group with IDC-P was associated with a 3-fold increase in prostate cancer-specific mortality to the group without IDC-P (p=0.037).

CONCLUSIONS: Patients with IDC-P at RP specimens have more advanced disease, shorter biochemical recurrence-free, and cancerspecific survival than those without IDC-P. Defining the presence of IDC-P in RP specimens is critical in choosing the appropriate treatment strategy and predicting the prognosis.
