Treatment Outcomes in Patients with Recurrent Adrenocortical Carcinoma.

BACKGROUND: While numerous studies have explored treatment outcomes for the overall ACC patient cohort, data on the subpopulation of patients with recurrent disease are limited. Therefore, the aim of this study was to assess treatment outcomes in patients with recurrent ACC. METHODS: In this retrospective study, we included 18 patients median age 49 years (42-62); 67% female) diagnosed with recurrent ENSAT stage I-III ACC who underwent either R0 (n = 16) or Rx (n = 2) surgical resection of the tumor. RESULTS: The median time from the initial surgery to ACC recurrence was 29 months (IQR 18-50). Seven patients (39%) manifested local recurrence, while 11 patients (61%) developed distant metastases. The median follow-up duration after tumor recurrence was 32 months (IQR 25-53). Regarding the treatment of ACC recurrence, 10 patients underwent a second surgery either as an alone procedure (n = 4), or in combination with mitotane (n = 4), mitotane and chemotherapy (n = 1), or mitotane combined with radiotherapy (n = 1). The remaining patients received treatment involving chemotherapy±mitotane (n = 4) and locoregional therapy ±chemotherapy (n = 3). One patient chose not to proceed with further management and follow-up. The median PFS was 17 (95% CI 8-26) months while the median OS was not reached. In the multivariate model, increased mortality was associated with advanced age (p = 0.04) and a shorter interval to ACC recurrence (p = 0.03). CONCLUSION: A significant proportion of patients with ACC recurrence experience disease progression or second recurrence, despite all treatment efforts. Nevertheless, by integrating diverse treatment modalities, many patients have the potential to attain long-term survival.

SHORT-TERM OUTCOMES OF PERCUTANEOUS RADIOFREQUENCY AND MICROWAVE ABLATION IN THE TREATMENT OF SMALL RENAL MASSES.

Although the gold standard in the management of kidney tumors is surgical treatment, thermal ablation methods are a viable therapeutic option for patients with small (<4 cm) renal masses who are poor surgical candidates. The aim of this study was to compare the technical success, primary efficacy and complication rate of percutaneous radiofrequency and microwave ablation in the treatment of small renal masses. A retrospective analysis of consecutive patients with small renal masses treated with radiofrequency or microwave ablation between December 2017 and January 2022 was conducted. Response to the ablative therapy was assessed on contrast-enhanced computed tomography examination after 3 months. Ablations of 44 kidney lesions were performed in 43 patients. Sixteen lesions were treated with radiofrequency and 28 with microwave ablation. Both methods were associated with high technical success (100%). Primary efficacy rates of radiofrequency and microwave ablation were 81.3% and 89.3%, respectively. Ablation-related complications were noted only in the patients treated with microwave ablation (18.5%), all of them being low grade (Clavien-Dindo 1 and 2). Radiofrequency and microwave ablation exhibited comparable efficacy in the treatment of small renal masses. Microwave ablation was associated with a comparatively higher number of complications.

Open vs laparoscopic adrenalectomy for localized adrenocortical carcinoma.

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.

Targeted prostate biopsy using a cognitive fusion of multiparametric magnetic resonance imaging and transrectal ultrasound in patients with previously negative systematic biopsies and non-suspicious digital rectal exam.

AIM: To compare cognitive fusion targeted and systematic prostate biopsy in patients with repeated negative systematic biopsy but persistent clinical suspicion for prostate cancer. METHODS: The study enrolled 63 patients with at least one previously negative systematic biopsy who underwent targeted prostate biopsy using multiparametric magnetic resonance imaging (mpMRI) and transrectal ultrasound (TRUS) in addition to standardized systematic biopsy from July 2016 to May 2018. Multiparametric MRI was performed with 3 Tesla device by uro-radiologists experienced in prostate cancer. Lesions with Prostate Imaging Reporting and Data System 3, 4, and 5 were considered suspicious. Targeted biopsies were performed with cognitive fusion of TRUS and mpMRI. RESULTS: Prostate cancer detection, using either targeted or systematic biopsy, was 60.32%. Targeted biopsies were positive in 52.38% and systematic biopsies in 47.62% of patients. The median highest percentage of cancer involvement per biopsy core was significantly higher in targeted cylinders. The biopsies obtained by using the two techniques did not significantly differ in Gleason score. CONCLUSION: Cognitive targeted prostate biopsy based on mpMRI presents a valuable addition to systematic biopsy in patients with repeated negative systematic biopsies but persistent clinical suspicion of prostate cancer.

Successful separation of xypho-omphalopagus conjoined twins with extrauterine twin-twin transfusion syndrome: a case report.

Conjoined twining is a rare medical phenomenon, with an overall prevalence of 1.47 per 100 000 births. This report describes a successful separation of xypho-omphalopagus conjoined twins complicated by unbalanced blood shunting through the porto-systemic anastomoses within the shared liver parenchyma. Significant extrauterine twin-twin transfusion syndrome caused by unbalanced shunting is an extremely rare, and probably under-recognized, hemodynamic complication in conjoined twins necessitating urgent separation. Progressive deterioration with a poor outcome can be prevented if the condition is recognized in a timely manner.

Case report: Urgent liver pathologies: All in one.

Ruptured hepatocellular carcinoma (HCC) is a well-known serious complication of this most common primary liver malignancy. However, when HCC rupture is associated with other focal liver lesions, the diagnosis and therapy may be very challenging. Correct differentiation of focal liver lesions is of paramount importance for successful treatment. The aim of this report is to present a unique case of HCC rupture complicated with liver abscess, hematoma and portal vein thrombosis. We discuss possible pathophysiological mechanisms and radiologic findings of such clinical scenarios and review literature related to the management of HCC rupture.

Pulmonary embolism during the third cycle of alemtuzumab in a patient with relapsing multiple sclerosis.

Alemtuzumab is one of immunomodulatory drugs used for treatment of multiple sclerosis (MS). Although it is very effective it carries significant risk for various side effects. This paper reports a case of young patient who developed pulmonary embolism during the third cycle of alemtuzumab. It is suggested that awareness about possible vascular toxicity of this drug should be raised.

Correlation of MRI features and pathohistological prognostic factors in invasive ductal breast carcinoma.

OBJECTIVE: The aim of this study was to correlate magnetic resonance imaging (MRI) features of invasive ductal carcinomas (IDC) with pathohistological prognostic factors. Such an association, if present, could have significant translational implications for early identification of aggressive types of breast cancer. MATERIALS AND METHODS: One hundred and fourteen consecutive women with IDC who underwent breast MRI within one month prior to surgery were included in this retrospective study. MRI features were analyzed and then interpreted with a Göttingen score (GS) that included morphological (shape, margins, and pattern of enhancement) and kinetic characteristics (initial signal increase and post-initial behavior of the time-signal intensity curve). Histological specimens were analyzed for tumor size, axillary lymph node status, histological grade, estrogen receptors (ER), progesterone receptors (PR), HER2, and Ki-67. RESULTS: By multivariate analysis, a smooth margin was a significant, independent predictor of a larger tumor size (p = 0.041), lymph node invasion (p = 0.013), and lower expression of ER (p = 0.022). High GS was a significant, independent predictor of a higher histological grade (p = 0.022) while round or oval shape of lesion was independent predictor of a higher PR expression (p = 0.027). CONCLUSION: A smooth margin of breast cancer on breast MRI was able to predict positive axillary lymph nodes, larger tumor size, and lower expression of ER. Except for a higher histological grade, GS was not able to predict other unfavorable prognostic factors, probably due to the fact that smooth margins were assigned fewer points than spiculated margins.

Role of breast imaging in predicting outcome of lesions of uncertain malignant potential (B3) diagnosed at core needle biopsy.

AIMS: To elucidate whether breast imaging can predict final histologic diagnosis of lesions of uncertain malignant potential diagnosed at ultrasound core needle biopsy (CNB). METHODS: The imaging characteristics (mammography, ultrasound, and magnetic resonance imaging [MRI]) of lesions of uncertain malignant potential in the breast that were obtained by ultrasound CNB were retrospectively analyzed in 87 women. Radiologic characteristics of lesions were compared to definitive histopathologic findings. RESULTS: Out of 87 breast lesions of uncertain malignant potential, 27 (31%) were diagnosed as papillary lesions, 24 (28%) atypical ductal hyperplasia, 19 (22%) lobular intraepithelial neoplasia, 9 (10%) phyllodes tumors, 3 (3%) radial sclerosing lesions, and 5 (6%) unspecified lesions of uncertain malignant potential. The underestimation rate of malignancy at CNB based on the total number of lesions on final follow-up was 22%. Using multivariate logistic regression, Breast Imaging-Reporting and Data System (BI-RADS) score (odds ratio [OR] = 12.29, p = 0.027) and Göttingen MRI scoring system (OR = 8.1, p = 0.008) were found to be independent predictors of malignancy. Receiver operating characteristic analysis showed that Göttingen MRI score >3 provides a plausibly good cutoff value with sensitivity of 100 (95% confidence interval [CI] 74%-100%) and specificity of 76% (95% CI 61%-88%). CONCLUSIONS: Lesions of uncertain malignant potential classified as BI-RADS 5 and Göttingen score 4 or higher are at significantly higher risk of harboring malignancy and therefore should be recommended for surgical excision.
