[PMID: 38491421 PMCID: PMC10943841 DOI: 10.1186/s12887-024-04673-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/16/2024] [Accepted: 02/26/2024] [Indexed: 03/18/2024] Open
Abstract
BACKGROUND The aim of this study was to investigate the clinical features and treatment options for pediatric adrenal incidentalomas(AIs) to guide the diagnosis and treatment of these tumors. METHODS The clinical data of AI patients admitted to our hospital between December 2016 and December 2022 were collected and retrospectively analyzed. All patients were divided into neonatal and nonneonatal groups according to their age at the time of the initial consultation. RESULTS In the neonatal group, 13 patients were observed and followed up, and the masses completely disappeared in 8 patients and were significantly reduced in size in 5 patients compared with the previous findings. Four patients ultimately underwent surgery, and the postoperative pathological diagnosis was neuroblastoma in three patients and teratoma in one patient. In the nonneonatal group, there were 18 cases of benign tumors, including 9 cases of ganglioneuroma, 2 cases of adrenocortical adenoma, 2 cases of adrenal cyst, 2 cases of teratoma, 1 case of pheochromocytoma, 1 case of nerve sheath tumor, and 1 case of adrenal hemorrhage; and 20 cases of malignant tumors, including 10 cases of neuroblastoma, 9 cases of ganglioneuroblastoma, and 1 case of adrenocortical carcinoma. CONCLUSIONS Neuroblastoma is the most common type of nonneonatal AI, and detailed laboratory investigations and imaging studies are recommended for aggressive evaluation and treatment in this population. The rate of spontaneous regression of AI is high in neonates, and close observation is feasible if the tumor is small, confined to the adrenal gland and has no distant metastasis.

Association of Surgical Approach With Treatment Burden, Oncological Effectiveness, and Perioperative Morbidity in Adrenocortical Carcinoma. Clin Genitourin Cancer 2022; 20:497.e1-497.e7.

Abstract
MICROABSTRACT In the National Cancer Database (NCDB), patients treated with minimally invasive adrenalectomy (MIA) for adrenocortical carcinoma (ACC) had similar oncological outcomes and cumulative treatment burden with less morbidity compared with open adrenalectomy (OA). Although OA remains the standard of care for adrenal lesions concerninge for malignancy, MIA in appropriately selected patients may offer equivalent oncological outcomes. INTRODUCTION/BACKGROUND We investigated the cumulative treatment burden, oncological effectiveness, and perioperative morbidity in patients undergoing MIA compared with (OA) for patients with ACC. PATIENTS AND METHODS We reviewed the NCDB for patients undergoing surgical resection (MIA vs. OA) for ACC from 2010 to 2017. Inverse probability of treatment weighted logistic regression, negative binomial, and Cox proportional hazards models were fit to assess for an association of surgical approach with cumulative treatment burden (any adjuvant therapy, radiation therapy [RT], and systemic therapy), oncological effectiveness (positive surgical margins [PSM], lymph node yield [LNY], and overall survival [OS]), and perioperative morbidity (length of stay [LOS] and readmission) as appropriate. RESULTS We identified 776 patients that underwent adrenalectomy for ACC, of which 307 underwent MIA. We noted patients with larger tumors (OR 0.82, 95% CI 0.78-0.86, P < .001) were less likely to have MIA prior to IPTW. We did not appreciate a significant association of MIA with cumulative treatment burden or the use of any adjuvant therapy (OR 0.85, 95% CI 0.60-1.21, P = .375), adjuvant RT (OR 0.94, 95% CI 0.59-1.50, P = .801), or adjuvant systemic therapy (OR 0.84, 95% CI 0.58-1.21, P = .352). Patients undergoing MIA had similar oncological effectiveness of surgery and OS when compared with patients which underwent OA. Patients that underwent MIA had a significantly shorter LOS (IRR: 0.74, 95% CI 0.62-0.88, P = .001) and lower odds of readmission (OR 0.46, 95% CI 0.23-0.91, P = .026). CONCLUSIONS Although the standard of care for adrenal lesions suspicious for ACC remains OA, in appropriately selected patients, MIA may offer similar oncological effectiveness and cumulative treatment burden, with less morbidity, than OA.

Novel Insights into the Molecular Regulation of Ribonucleotide Reductase in Adrenocortical Carcinoma Treatment. Cancers (Basel) 2021; 13:cancers13164200. [PMID: 34439352 PMCID: PMC8391410 DOI: 10.3390/cancers13164200] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/07/2021] [Revised: 08/11/2021] [Accepted: 08/13/2021] [Indexed: 12/20/2022] Open
Abstract
Simple Summary The current clinical gold standard etoposide, doxorubicin, cisplatin, and mitotane (EDP-M) is not satisfying for the treatment of adrenocortical carcinoma (ACC). However, clinical translation of novel, preclinically promising therapies were unfortunately disappointing in recent years, indicating that utilized tumor models inadequately predicted clinical applicability of novel pharmacological approaches. In an attempt to optimize the current preclinical armamentarium, our workgroup initiated a comparative drug screen of clinically relevant chemotherapies and therapies targeting IGF, EGF, and Wnt signaling pathways in the classical NCI-H295R cell line and, for the first time, in the recently developed highly drug-resistant MUC-1 cell line. These testings revealed gemcitabine and cisplatin as a promising combination, but further investigations also indicated developing drug resistance mechanisms on the molecular level. We aimed to decipher underlying resistance mechanisms, identified ribonucleotide reductase as an important player, and successfully targeted the involved DNA damage/repair mechanism. Abstract Current systemic treatment options for patients with adrenocortical carcinomas (ACCs) are far from being satisfactory. DNA damage/repair mechanisms, which involve, e.g., ataxia-telangiectasia-mutated (ATM) and ataxia-telangiectasia/Rad3-related (ATR) protein signaling or ribonucleotide reductase subunits M1/M2 (RRM1/RRM2)-encoded ribonucleotide reductase (RNR) activation, commonly contribute to drug resistance. Moreover, the regulation of RRM2b, the p53-induced alternative to RRM2, is of unclear importance for ACC. Upon extensive drug screening, including a large panel of chemotherapies and molecular targeted inhibitors, we provide strong evidence for the anti-tumoral efficacy of combined gemcitabine (G) and cisplatin (C) treatment against the adrenocortical cell lines NCI-H295R and MUC-1. However, accompanying induction of RRM1, RRM2, and RRM2b expression also indicated developing G resistance, a frequent side effect in clinical patient care. Interestingly, this effect was partially reversed upon addition of C. We confirmed our findings for RRM2 protein, RNR-dependent dATP levels, and modulations of related ATM/ATR signaling. Finally, we screened for complementing inhibitors of the DNA damage/repair system targeting RNR, Wee1, CHK1/2, ATR, and ATM. Notably, the combination of G, C, and the dual RRM1/RRM2 inhibitor COH29 resulted in previously unreached total cell killing. In summary, we provide evidence that RNR-modulating therapies might represent a new therapeutic option for ACC.

BMC Med Genomics 2020; 13:165. [PMID: 33148256 PMCID: PMC7640690 DOI: 10.1186/s12920-020-00809-7] [Citation(s) in RCA: 14] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/23/2019] [Accepted: 10/14/2020] [Indexed: 12/29/2022] Open
Abstract
BACKGROUND Adrenocortical carcinoma (ACC) is a rare, often-aggressive neoplasm of the adrenal cortex, with a 14-17 month median overall survival. We asked whether tumors from patients with advanced or metastatic ACC would offer clues as to putative genes that might have critical roles in disease progression or in more aggressive disease biology. METHODS We conducted comprehensive genomic and expression analyses of ACCs from 43 patients, 30 female, and 42 from metastatic sites, including deep sequencing, copy number analysis, mRNA expression and microRNA arrays. RESULTS Copy number gains and losses were similar to that previously reported for ACC. We identified a median mutation rate of 3.38 per megabase (Mb). The mutational signature was characterized by a predominance of C > T, C > A and T > C transitions. Only cancer genes TP53 (26%) and beta-catenin (CTNNB1, 14%) were mutated in more than 10% of samples. The TCGA-identified putative cancer genes MEN1 and PRKAR1A were found in low frequency-4.7 and 2.3%, respectively. The majority of the mutations were in genes not implicated in the etiology or maintenance of cancer. Specifically, amongst the 38 genes that were mutated in more than 9% of samples, only four were represented in Tier 1 of the 576 COSMIC Cancer Gene Census (CCGC). Thus, 82% of genes found to have mutations likely have no role in the etiology or biology of ACC; while the role of the other 18%, if any, remains to be proven. Finally, the transcript length for the 38 most frequently mutated genes in ACC is statistically longer than the average of all coding genes, raising the question of whether transcript length in part determined mutation probability. CONCLUSIONS We conclude that the mutational and expression profiles of advanced and metastatic tumors are very similar to those from newly diagnosed patients-with very little in the way of genomic aberration to explain differences in biology. With relatively low mutation rates, few major oncogenic drivers, and loss of function mutations in several epigenetic regulators, an epigenetic basis for ACC may be postulated and serve as the basis for future studies.

Abstract
BACKGROUND Recurrent adrenocortical carcinoma (ACC) is an aggressive disease with few options offering durable survival benefit. Despite metastasectomy, recurrence is common. Cytoreduction and intraperitoneal chemotherapy have offered improved survival in other advanced cancers. We sought to evaluate the use of cytoreduction and hyperthermic intraperitoneal chemotherapy (HIPEC) for the treatment of recurrent intraperitoneal ACC. METHODS A phase II, single institution clinical trial was approved for patients with radiographic evidence of resectable ACC limited to the peritoneum. Patients underwent treatment if optimal cytoreduction was deemed possible at exploratory laparotomy. Primary outcome was intraperitoneal progression-free survival. Secondary outcomes were treatment-related morbidities and overall survival. RESULTS Sixty-three patients were evaluated, of whom 11 met eligibility criteria. Nine patients underwent cytoreduction and HIPEC, including one patient who recurred and was re-treated (n = 10 treatments). One patient could not be optimally cytoreduced for HIPEC and therefore did not receive intraperitoneal chemotherapy. There was no perioperative mortality; perioperative comorbidities were limited to Clavien-Dindo grade 2 or 3 and included hematologic, infectious, and neurologic complications. Seven patients experienced disease recurrence and two patients died of disease during follow-up (median 24 mo). Intraperitoneal progression-free survival was 19 mo, and median overall survival has not yet been reached. CONCLUSIONS Cytoreduction and HIPEC can be performed safely in selected patients. Patients with recurrent ACC confined to the peritoneal cavity can be considered for regional therapy in experienced hands. However, disease recurrence is common, and other treatment options should be explored.

Abstract
Adrenalectomy is the standard of care for management of many adrenal tumor types and, in the United States alone, approximately 6000 adrenal surgeries are performed annually. Two general approaches to adrenalectomy have been described; (1) the open approach, in which a diseased adrenal is removed through a large (10-20 cm) abdominal wall incision, and (2) the minimally invasive approach, in which laparoscopy is used to excise the gland through incisions generally no longer than 1-2 cm. Given these disparate technique options, clear preoperative characterization of those specific disease features that inform selection of adrenalectomy approach is critically important to the surgeon. Because most of these features are directly assessed via preoperative abdominal imaging, in particular computed tomography (CT) scanning, a clear mutual understanding among surgeons and radiologists of those adrenal tumor features impacting operative approach selection is vital for planning adrenal surgery. In this context, we review the preoperative CT imaging features that specifically inform adrenalectomy approach selection, provide illustrative examples from our institution's imaging and surgical archives, and provide a stepwise guide to both the open and laparoscopic adrenalectomy approaches.

Abstract
Telomere maintenance, most commonly achieved by telomerase activation through induction of the telomerase reverse transcriptase (TERT) gene, is required for cell immortalization, a hallmark of cancer. Adrenocortical carcinoma (ACC) is an endocrine tumor for which TERT promoter mutations and telomerase activation have been reported. The present study assessed alterations of the TERT gene locus and telomere length in relation to clinical characteristics in ACC. In total, 38 cases of ACC with known TERT promoter mutational status were included. TERT promoter methylation densities were assessed by pyrosequencing, and TERT copy numbers and telomere length were determined by quantitative polymerase chain reaction analysis, followed by comparison of the mRNA expression of TERT and clinical parameters. The ACC tissue samples showed increased TERT copy numbers, compared with normal adrenal tissue (NAT) samples (P=0.001). Mutually exclusive TERT copy number gains or promoter mutation were present in 70% of the ACC samples. The ACC tissues exhibited higher levels of CpG promoter methylation of all eight CpG sites investigated within the ‑578 to ‑541 bp (Region A), compared with the NATs (P=0.001). High methylation density at this region was associated with metastatic disease and/or relapse, poor survival rates and higher European Network for the Study of Adrenal Tumor stage (P<0.05). The mRNA expression of TERT was inversely correlated with methylation density at ‑162 to ‑100 bp (Region B). Correlation was observed between relative telomere length and the gene expression of TERT. It was concluded that epigenetic alterations of the TERT promoter are frequent and associated with advanced disease and poorer clinical outcome in ACC.

Abstract
Adrenocortical carcinoma (ACC) is a rare malignancy with poor prognosis. It has undergone in-depth clinical and laboratory investigations, with the help of the most important research groups all over the world. Nonetheless the cure for this kind of neoplasia is not right around the corner, given its complexity and multi-faceted feature, that lead researchers to think at "one person one ACC." Currently total resection is the most concrete option for ACC patients, whenever possible. Mitotane remains the main drug for primary or adjuvant therapy, but gives partial and unsatisfactory therapeutic results, especially in metastatic ACC. This prompted the researchers to find other ways to fight against this malignancy: targeted therapy seems the most promising answer, as it is based on biomolecular and genetic cancer signature. Numerous specific targets were explored for the treatment of ACC, such as those involving angiogenesis, steroidogenesis, Wnt/β-catenin pathway and many others key factors. Even if large efforts have been made, no effective target therapy entered in the clinical use. This data should not be considered only as detrimental, rather it should propel scientific research to invest more resources into the therapeutic exploration of ACC and in particular on the most promising strategy, the targeted therapy.

Abstract
Aim Adrenocortical carcinoma (ACC) is characterized with excessive hormone production. We therefore investigated expression of hormone-related genes in ACC. Results We queried status of 14 key genes directly involved in adrenal hormone production and found HSD17B4 expression was upregulated in 39% of ACC cases on top of all queried genes. Overexpression of HSD17B4 was significantly associate with a normo-hormonal phenotype. Constitutive HSD17B4 expression was higher in ACC cell line NCI-H295R than in adrenocortical small cell carcinoma cell line SW13. NCI-H295R cells with HSD17B4-knockdown (KD) demonstrated significantly inhibited proliferation, increased apoptosis, and increased cell cycle arrest. Enrichment analysis for mRNA expression in ACC samples with or without HSD17B4 overexpression showed significant change in p53 pathway. Replenish of HSD17B4 in SW13 cells and knockdown of HSD17B4 in H295R cells confirmed alterations in MDM4, ATR, and IE24 with alterations more contrasting in H295R cells. HSD17B4-KD inhibited cell invasion, migration and anchorage independent growth of NCI-H295R cells, but not of SW13 cells. Materials and Methods Clinical and genetic data of ACC samples were reproduced from the ACC dataset of The Cancer Genome Atlas (TCGA) database using cBioPortal. Genes participating in adrenal hormone production were queried. Association between gene status and hormone release were studied and in vitro assays using RNA interference were carried out. Conclusions Overexpression of HSD17B4 exerted tumor suppressive function in adrenocortical carcinoma and was not related to hormone excess. Crosstalk between HSD17B4 and p53 warrants further investigation.

Abstract
Most endocrine tumors are benign, and afflicted patients usually seek medical advice because of symptoms caused by too much, or too little, native hormone secretion or the impingement of their tumor on a vital structure. Malignant endocrine tumors represent a more serious problem, and patient cure often depends on early diagnosis and treatment. The recent development of novel molecular therapeutics holds great promise for the treatment of patients with locally advanced or metastatic endocrine cancer. In this CCR Focus, expert clinical investigators describe the molecular characteristics of various endocrine tumors and discuss the current status of diagnosis and treatment.
