RESUMEN
Prostate cancer (PC) is the most frequent cancer in males, as well as the second highest cause of cancer-related deaths in men. Differences in expression levels of miRNAs were linked with prostat cancer pathogenesis. qPCR was used to evaluate the expression of miR-130b-3p and miR-375 in Benign Prostate Hyperplasia (BPH (n = 20) and PC (n = 22, pre- and post-operative) patients plasma. Relative telomere lengths (RLTs) in genomic DNA isolated from plasma were measured with qPCR, and telomerase activity analyzed by the ELISA method. PSA levels of PC patients were greater than of BPH patients (p = 0.0473). miR-130b-3p and miR-375 levels were significantly lower in pre-operative specimens of PC patients according to BPH (p = 0,0362, p = 0.0168, respectively). Similarly, post-operative miR-375 levels were lower in PC patients than in BPH patients (p = 0.1866). BPH patients had shorter RTLs than PC patients in both pre- (p=0.0438) and post-operative (p=0.0297) specimens. Telomerase activity was higher in PC patients than BPH(p = 0.0129). Interestingly, telomerase activity was further increased after surgery (p = 0.0003). We aim to identify the levels of miR-130b-3p and miR-375 expression and their relationship with telomerase activity in PC patients. Our data suggest that miRNAs and telomere length (TL) with telomerase activity may play a role in regulating prostate tumorgenesis and may be used as biomarkers for PC diagnosis.
RESUMEN
Objectives: We aimed to compare the outcomes of patients who underwent laparoscopic adrenalectomy (LA) for pheochromacytoma (PHE) ≥5 cm versus <5 cm in diameter. Methods: Demographic variables, tumor characteristics, perioperative, and post-operative outcomes were evaluated retrospectively and compared between groups. Results: Between February 2008 and August 2020, 54 patients (27 female and 27 male) enrolled to the study and divided into two groups according to the tumor size as group L ≥5 cm (28 patients) and group S as <5 cm (26 patients). Groups compared in the aspect of American Society of Anesthesiologists scores, body mass index, tumor locations, ratio of elder (≥60-years-old) patients, and gender ratio were similar between groups S and L (p=0.572, p=0.516, p=0.6, p=0.331, and p=0.207, respectively). Mean duration of surgery (p=0.266), mean estimated blood loss (p=0.587), and mean length of hospital stay (p=0.374) were similar between groups. Difference between maximum and pre-operative systolic pressure and the difference between maximum and pre-operative diastolic pressure were similar between S and L groups (p=0.852 and p=0.526, respectively). Patients whose systolic blood pressure >160 mmHg, systolic blood pressure >30% of baseline, and heart rate >110 (p=0.307, p=0.609, and p=0.296) were similar. Diastolic blood pressure <30%, there is a difference between groups in favor of group L, but not statistically different (p=0.077). Conclusion: It is necessary to work in coordination with endocrinologists and anesthesiologists and LA for PHE should be performed in experienced medical centers regardless of tumor size with multidisciplinary approach.
RESUMEN
OBJECTIVE: This study aimed to compare the right and left side laparoscopic donor nephrectomy (LDN) outcomes of a single center. MATERIALS AND METHODS: The outcomes of patients who underwent LDN in our clinic between 2008 and 2020 were evaluated retrospectively. Two groups were consisted according to the side of the donor kidney. The gender, age, body mass index, duration of operation, amount of bleeding, warm ischemia time, drain removal time, and duration of hospitalization and complications were compared between groups. RESULTS: A total of 314 patients were included in the study. Sixty-six patients underwent right LDN and 248 underwent left LDN. There was no difference between groups in terms of age, duration of operation, amount of bleeding, warm ischemia time, and complications (p>0.05). However, drain removal time and duration of hospitalization were longer in the left LDN group (p<0.05). CONCLUSIONS: The right LDN had similar intraoperative outcomes with the left LDN. However, failure on meticulous dissection of the lymphatic structures during left LDN might cause chylous drainage and prolonged hospitalization time.
