Objective
The purpose of the study was to compare the long‐term outcomes of patients with localized adrenocortical carcinoma (ACC) subjected to open vs laparoscopic surgery.
Design
Retrospective ...study.
Patients
This retrospective study included 46 patients with the ACC ENSAT stage I‐stage III of whom 23 underwent open surgery (OA group), whereas 23 were subjected to laparoscopic adrenalectomy (LA group). The main outcomes analysed in the study were differences between the OA and LA groups in recurrence‐free survival (RFS) and overall survival (OS).
Results
Patients in OA group had larger tumours (120 70‐250 mm vs 75 26‐110 mm; P < .001), higher Ki‐67 index (16 1‐65 % vs 10 1‐25 %; P = .04) and higher disease stage (P = .01) compared with the patients in the LA group. The median duration of follow‐up for patients underwent OA and LA was 51 (12‐174) and 53 (5‐127) months, respectively. Eight patients (5 OA and 3 LA) experienced recurrent disease, whereas six patients (3 OA and 3 LA) died during follow‐up. No differences in RFS and OS were found between patients who underwent open or laparoscopic surgery.
Conclusion
The study demonstrated that in patients with localized ACC and without invasion of extra‐adrenal tissues, LA is a plausible treatment option in terms of RFS and OS. However, our results are limited to referral centres with large experience in the management of patients with ACC and may not necessarily apply to nonspecialized centres.

The purpose of the present study was to analyze the impact of the neutrophil-lymphocyte ratio (NLR) on the long-term outcomes of patients with adrenocortical carcinoma (ACC).
This retrospective, ...single-institution study included 48 patients with the diagnosis of ACC. The primary outcomes of the study were differences in overall survival (OS) and disease-specific survival (DSS) with respect to the NLR level.
Patients with ENSAT stage IV had higher levels of NLR compared to those with ENSAT stage I-III (5.7 (1.6-12.5) vs 3.3 (1.3-11); p = .01). A higher NLR was also observed among patients with cortisol-secreting tumors (4.6 (1.7-12.5) vs 2.8 (1.3-10.3); p = .003) and those with Ki-67 index >10% (4.3 (1.3-12.5) vs 2.6 (1.6-11.0); p = .005). With respect to survival, the univariate analysis revealed worse ACC-related survival (p = .02) and OS (p = .004) in patients with NLR >3.9 than in those with NLR ≤3.9. In addition, patients with NLR >3.9 had a higher Weiss score (p = .046), a higher Ki-67 index (p = .006) and a higher disease stage (p = .01) compared to patients with NLR ≤3.9. No differences between the groups were observed regarding excess glucocorticoid secretion.
The study demonstrated that a higher NLR level in ACC patients was associated with unfavorable outcomes in terms of DSS and OS. These results indicate that NLR might be used as an additional marker in ACC risk stratification and identification of patients with the most adverse prognosis.

Dishevelled family proteins (DVL1, DVL2, and DVL3) are cytoplasmic mediators involved in canonical and non-canonical Wnt signaling that are important in embryonic development. The role of DVL ...proteins in the placental tissue remains mostly unknown. In the current study, we explored the role of Dishevelled proteins in naturally invasive tissue, trophoblast. Formalin-fixed paraffin-embedded samples of 15 term placentas from physiologic term pregnancies and 15 term placentas from pregnancies complicated with intrauterine growth restrictions (IUGR) were used for the study. Expression levels of mRNA for DVL1, DVL2, and DVL3 in placentas were analyzed by quantitative real-time PCR (qRT-PCR). DVL1, DVL2, and DVL3 protein expression were semi-quantitatively analyzed using immunohistochemistry. The expression of DVL2 and DVL3 proteins was significantly higher in trophoblasts in placental villi from IUGR pregnancies compared with the control group of term placentas. In contrast, DVL3 protein expression was significantly higher in endothelial cells in placental villi from IUGR pregnancies compared with normal term placentas. The observed differences at protein levels between normal and IUGR placentas were not confirmed at the mRNA levels of DVL genes. Our data indicate the active involvement of DVL proteins in IUGR-related placentas. No significant changes were observed in DVL mRNA levels between the two groups of placentas. Further studies are required to explore the clinical relevance of these observations.
