The effect of diagnosis delay in testis cancer on tumor size, tumor stage and tumor markers.

INTRODUCTION: In testicular cancer, the positive effect of early diagnosis on survival has been known for many years. In this study, we aimed to determine the diagnostic features of testicular cancer patients, to examine the effect of duration of diagnosis delay (DD) on tumor size, tumor stage, and serum tumor markers, and to reveal the possible benefits of early diagnosis.

METHODS: A total of 71 patients who underwent inguinal orchiectomy due to suspicion of testicular cancer and whose pathology was found to be the germ cell tumor were included in the study. The relationship between the duration of diagnosis delay and tumor size, level of tumor markers, TNM stage, presence of LAP, and presence of metastasis were examined.

RESULTS: Seminoma was detected in 39 (54.9%) patients and non-seminoma tumor was detected in 32 (45.1%) patients. In the correlation analysis between the markers, a significant and positive correlation was found between DD and radiological tumor size, pathological tumor size, retroperitoneal LAP detection rate, LDH and AFP levels, and N stage (respectively; r=0.345 p=0.003, r=0.324 p=0.006, r=0.244 p=0.041, r=0.286 p=0.015, r=0.244 p=0.040, r=0.238 p=0.046). It was determined that a 1-day increase in DD caused an increase of 0.431mm in the pathological size of the tumor.

CONCLUSION: Duration of diagnosis delay is an issue that still keeps its importance for testicular tumors. Delay in diagnosis not only leads to an increase in tumor size but also negatively affects tumor stage and prognostic factors.
