Inflammation-based scores in a large cohort of adrenocortical carcinoma and adrenocortical adenoma: role of the hormonal secretion pattern
Background Serum inflammation-based scores can predict clinical outcome in several cancer types, including adrenocortical carcinoma (ACC). It is unclear whether the extent of inflammation-based scores alterations in ACC reflects malignancy, steroid excess, or both. Methods We investigated a large retrospective cohort of adrenocortical adenomas (ACA, n  = 429) and ACC ( n  = 61) with available baseline full blood count and hormonal evaluation. We examined the relationship between different inflammation-based scores [neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), lymphocyte-to-monocyte ratio (LMR), systemic immune-inflammation index (SII), and prognostic nutrition index (PNI)] and both malignancy and steroid secretion patterns. Results All inflammation-based scores differed between ACC and ACA: patients with ACC had higher NLR, PLR, SII and lower LMR and PNI levels compared to ACA (all p values < 0.001). NLR showed a positive correlation with cortisol levels after overnight 1 mg-dexamethasone suppression test (1 mg-DST), both in ACC and ACA ( p  < 0.01). The ROC curve analysis determined NLR > 2.6 as the best cut-off to discriminate ACC from ACA [AUC = 0.846, p  < 0.01]. At multivariable analysis, NLR > 2.6 was independently associated with ACC, 1 mg-DST cortisol levels and age, but not with tumour size. Considering the ACC, NLR and SII were higher and PNI was lower in patients with cortisol excess compared to those without cortisol excess ( p  = 0.002, p  = 0.007, and p  = 0.044 respectively). Finally, LMR and NLR differed between inactive-ACC ( n  = 10) and inactive-ACA ( n  = 215) ( p  = 0.040 and p  = 0.031, respectively). Conclusion Inflammation-based scores are related to steroid secretion both in ACC and ACA. ACCs present a higher grade of inflammation regardless of their hormonal secretion, likely as a feature of malignancy itself.
Efficacy of the EDP-M Scheme Plus Adjunctive Surgery in the Management of Patients with Advanced Adrenocortical Carcinoma: The Brescia Experience
Etoposide, doxorubicin and cisplatin plus oral mitotane (EDP-M) comprise the reference regimen in the management of patients with adrenocortical carcinoma (ACC). In this paper, we described the outcome of 58 patients with advanced/metastatic ACC consecutively treated with EDP-M in a reference center for this rare disease in Italy. In this series, EDP-M obtained a partial response in 50% of patients; median progression free survival (PFS) and overall survival were 10.1 months (95% Confidence Interval [CI 95%] 8.1–12.8) and 18.7 months (95% CI: 14.6–22.8), respectively. EDP-M was not interrupted in five patients showing disease progression after two cycles without the appearance of new lesions and mitotane levels below the therapeutic range. In two of them, the disease remained stable at further imaging evaluations and the other three obtained a partial response. Twenty-six responding patients underwent surgery of residual disease and 13 of them became disease free. Surgery identified a pathological complete response (pCR) in four patients (7%) and Ki67 expression in post-chemotherapy tumor specimens, inferior to 15% (median value), was associated with better PFS and survival. In the present study, the EDP-M regimen is confirmed to have a limited efficacy. Early disease progression does not mean treatment inefficacy. Surgery of residual disease in partially responding patients allows for the detection of pCR in few of them and this condition is predictive of long-term survival. Ki67 expression of post-chemotherapy residual disease could be an additional prognostic factor that deserves to be studied further.
The Endocrine Phenotype Induced by Pediatric Adrenocortical Tumors Is Age- and Sex-Dependent
Abstract Context Adrenocortical carcinomas are very rare malignancies in childhood associated with poor outcome in advanced disease. Most adrenocortical tumors (ACT) are functional, causing signs and symptoms of adrenal hormone excess. In most studies, endocrine manifestations were reported 4 to 6 months prior to diagnosis. Objective We sought to extend knowledge on endocrine manifestations with regard to age and sex to facilitate early diagnosis. Methods We retrospectively analyzed features of adrenal hormone excess in children and adolescents with ACT registered with the GPOH-MET studies between 1997 and 2022. Stage of puberty was defined as prepubertal in females < 8 years of age and males < 9 years. Results By December 2022, 155 patients (110 female, 45 male) with data on endocrine manifestations had been reported. Median age at ACT diagnosis was 4.2 years [0.1-17.8], median interval from first symptoms was 4.2 months [0-90.7]. In 63 girls of prepubertal age, the most frequently reported manifestations were pubarche (68.3%), clitoral hypertrophy (49.2%), and weight gain (31.7%); in 47 pubertal female patients, the most frequent manifestations were excessive pubic hair (46.8%), acne (36.2%), and hypertension (36.2%). Leading symptoms in 34 boys of prepubertal age were pubarche (55.9%), penile growth (47.1%), and acne (32.4%), while in 11 pubertal male patients, leading symptoms were weight gain (45.5%), hypertension (36.4%), excessive pubic hair (27.3%), and cushingoid appearance (27.3%). In pubertal patients, symptoms of androgen excess were mainly unrecognized as part of pubertal development, while symptoms of Cushing syndrome were more frequently apparent. Conclusion The endocrine phenotype induced by pediatric ACT is age- and sex-dependent.
Molecular and Clinical Features of Adrenocortical Tumors in Beckwith–Wiedemann Spectrum
Background/Objectives: Adrenocortical tumors (ACTs), including adrenocortical adenoma (ACA) and carcinoma (ACC), represent 0.3–0.4% of pediatric tumors. Beckwith–Wiedemann spectrum (BWSp) confer an increased risk of ACTs, but prognosis, management, and associated molecular characteristics are unclear. Methods: This paper combines a literature review of 54 published cases of BWSp-ACT with a report of one newly identified patient, totaling 55 cases with a confirmed BWSp clinical and/or molecular diagnosis. Results: Nineteen patients with ACA, 33 with ACC, and 3 with ACT of uncertain malignant potential (umACT) were included. Twenty patients had uniparental disomy of chromosome 11p15.5 (patUPD11), 11imprinting Center 2 Loss-of-methylation (IC2-LoM), and had 2 11p15 locus duplication. Eleven patients were diagnosed during cancer screening procedures, including two metastatic at diagnosis ACC. Conclusions: Almost half of ACC patients reached the minimum score for clinical BWSp diagnosis only after ACC onset, suggesting that the BWSp score has limited value for the early diagnosis in such a setting. Two patients with metastatic ACC had a histopathological Wieneke score ≤2, not correlating with clinical malignancy and confirming limitations of the current histopathological classification, as previously documented. Ultrasound screening failed identifying the ACC before metastasis in two cases, indicating an urgent need to develop new strategies for screening of ACTs in BWSp. Furthermore, some cases of metastatic ACC exhibited unexpectedly indolent behavior despite being malignant.
Adrenocortical Carcinoma in Childhood: A Systematic Review
Adrenocortical tumors are rare in children. This systematic review summarizes the published evidence on pediatric adrenocortical carcinoma (ACC) to provide a basis for a better understanding of the disease, investigate new molecular biomarkers and therapeutic targets, and define which patients may benefit from a more aggressive therapeutic approach. We included 137 studies with 3680 ACC patients (~65% female) in our analysis. We found no randomized controlled trials, so this review mainly reflects retrospective data. Due to a specific mutation in the TP53 gene in ~80% of Brazilian patients, that cohort was analyzed separately from series from other countries. Hormone analysis was described in 2569 of the 2874 patients (89%). Most patients were diagnosed with localized disease, whereas 23% had metastasis at primary diagnosis. Only 72% of the patients achieved complete resection. In 334 children (23%), recurrent disease was reported: 81%—local recurrence, 19% (n = 65)—distant metastases at relapse. Patients < 4 years old had a different distribution of tumor stages and hormone activity and better overall survival (p < 0.001). Although therapeutic approaches are typically multimodal, no consensus is available on effective standard treatments for advanced ACC. Thus, knowledge regarding pediatric ACC is still scarce and international prospective studies are needed to implement standardized clinical stratifications and risk-adapted therapeutic strategies.
Clinical characteristics and prognosis of adrenocortical tumors in children
PurposeThe purpose of this study was to review the clinical characteristics and prognosis of children with adrenocortical tumors (ACT).MethodsWe retrospectively reviewed the medical records of 28 patients with ACT at our hospital between March 2010 and March 2017.ResultsThe main clinical presentations were sexual prematurity (n = 17) and Cushing’s syndrome (n = 15). All patients without metastasis underwent complete resection by laparotomy (n = 19) or laparoscopic surgery (n = 9). Pathological diagnosis confirmed adrenocortical carcinomas (ACC, n = 12) and adrenocortical adenomas (ACA, n = 16). Dehydroepiandrosterone (939.4 ± 148.2 µg/dl vs 630.9 ± 376.3 µg/dl; p = 0.031) and testosterone (235.7 ± 89.1 ng/dl vs 164.6 ± 47.5 ng/dl; p = 0.012) were significantly increased in ACC compared with ACA. The ACC tumor volumes were larger than those in ACA (107.5 ± 69 vs 25.5 ± 23.1 cm3; average diameter 6 cm vs 4 cm p = 0.001) and the immunochemical expression of Ki-67 was higher in ACC than in ACA (30.2 ± 22.7 vs 9.9 ± 4.9 p = 0.013). The mean follow-up of patients with ACA was 40 ± 23 months without recurrence. Seven patients with ACC had postoperative distant metastases and five patients died within 2 years. Five patients with ACC survived with a median follow-up of 27 months. The 2-year overall survival was 44.6%.ConclusionsPatients with ACC had significantly larger tumor volumes than those with ACA. The discordantly elevated serum levels of sexual corticosteroid hormones and lactate dehydrogenase may predict the malignant nature of these tumors. The prognosis of patients with ACA was good, while those with ACC had high postoperative metastasis and mortality rates.
Ang–Tie Angiogenic Pathway Is Distinctively Expressed in Benign and Malignant Adrenocortical Tumors
The differential diagnosis between adrenocortical adenomas (ACAs) and adrenocortical carcinomas (ACCs) relies on unspecific clinical, imaging and histological features, and, so far, no single molecular biomarker has proved to improve diagnostic accuracy. Similarly, prognostic factors have an insufficient capacity to predict the heterogeneity of ACC clinical outcomes, which consequently lead to inadequate treatment strategies. Angiogenesis is a biological process regulated by multiple signaling pathways, including VEGF and the Ang–Tie pathway. Many studies have stressed the importance of angiogenesis in cancer development and metastasis. In the present study, we evaluated the expression of VEGF and Ang–Tie pathway mediators in adrenocortical tumors (ACTs), with the ultimate goal of assessing whether these molecules could be useful biomarkers to improve diagnostic accuracy and/or prognosis prediction in ACC. The expression of the proteins involved in angiogenesis, namely CD34, VEGF, VEGF-R2, Ang1, Ang2, Tie1 and Tie2, was assessed by immunohistochemistry in ACC (n = 22), ACA with Cushing syndrome (n = 8) and non-functioning ACA (n = 13). ACC presented a significantly higher Ang1 and Ang2 expression when compared to ACA. Tie1 expression was higher in ACC with venous invasion and in patients with shorter overall survival. In conclusion, although none of these biomarkers showed to be useful for ACT diagnosis, the Ang–Tie pathway is active in ACT and may play a role in regulating ACT angiogenesis.
Cardiac Myxoma Caused by Fumarate Hydratase Gene Deletion in Patient With Cortisol-Secreting Adrenocortical Adenoma
Abstract Context Germline mutations in fumarate hydratase (FH) gene are known to cause hereditary leiomyomatosis and renal cell carcinoma (HLRCC) and are occasionally accompanied with cutaneous and uterine leiomyoma or cortisol-producing adrenocortical hyperplasia. However, the association between FH mutations and cardiac or adrenocortical tumors has remained unknown. Here, we identified a novel deletion in FH, exhibiting cardiac myxoma and subclinical Cushing syndrome due to adrenocortical tumor. Case Description A 44-year-old man was referred to our hospital for cardiac and adrenal tumor evaluation. He had a history of multiple painful, dermal papules and nodules diagnosed as cutaneous leiomyoma. The surgically resected cardiac tumor was diagnosed as myxoma. The adrenal tumor was clinically diagnosed as subclinical Cushing syndrome. Laparoscopically resected adrenal tumor was pathologically diagnosed as adrenocortical adenoma harboring unique histological findings similar to primary pigmented nodular adrenocortical disease (PPNAD). DNA analysis revealed a germline deletion in FH c0.737delT (p. Phe225Leufs*31) and loss of heterozygosity (LOH) in cardiac myxoma. As a functional analysis of FH in cardiac myxoma, low FH protein expression with elevated 2-succinocysteine (2SC), a marker of FH dysfunction, was immunohistochemically detected. However, in adrenocortical tumor, LOH of FH was not detected, and FH or 2SC expression was not altered. Conclusions This is the first case of HLRCC complicated by cardiac myxoma. LOH of FH deletion and its dysfunction were identified in cardiac myxoma. The association between FH deletion and adrenocortical lesion, however, needs to be further clarified.
Clinical Impact of Pathological Features Including the Ki-67 Labeling Index on Diagnosis and Prognosis of Adult and Pediatric Adrenocortical Tumors
Adrenocortical tumors (ACT) in the adult and pediatric population are generally considered distinct entities due to differences in molecular events related to tumorigenesis, clinical presentation, and outcome. Furthermore, pathological criteria used for diagnosis and prognostication of ACT in adults are usually inadequate for predicting the biological behavior of ACT in children. Here, we analyzed 146 adult and 44 pediatric (< 15y/o) ACT with long-term clinical follow-up and furthered current evidence on the clinical and pathological differences between pediatric and adult tumors. Predilection for female over male gender was observed in both cohorts, but more so in adults (84% vs. 61%, p = 0.003). Cushing syndrome was more frequent in adults (p < 0.001), whereas virilization, either isolated (p < 0.001) or combined to Cushing (p = 0.047), was more common in children. The Ki67 labelling index (LI) of pediatric adenomas and carcinomas was much higher than their corresponding tumors in adults (p < 0.001). Despite these differences, pathological analyses including the evaluation of Ki67 greatly improved patient prognostication in both age cohorts. Indeed, increased Weiss scores and Ki67 indexes correlated with poor overall- and disease-free survival in adult patients with carcinoma. Among the proliferative indexes tested, Ki67 LI ≥ 10% showed the highest hazard ratio (HR) for recurrence and the Ki67 LI ≥ 3% showed the highest HR for survival. In pediatric tumors, the Wieneke score (p < 0.001) and the Ki67 LI (p < 0.001) showed high accuracy for predicting biological behavior, and increased scores/indexes correlated with worse overall and disease-free survival. In this age cohort, Ki67 LI < 10% was able to rule out malignant behavior, whereas Ki67 LI ≥ 15% may be used to predict the patients with higher risks of recurrence and/or poor outcome.
Feminizing Adrenocortical Tumors as a Rare Etiology of Isosexual/Contrasexual Pseudopuberty
Estrogen-secreting adrenocortical tumors (ACTs) are quite rare with feminizing adrenocortical tumors (FATs) accounting for 0.37-2% of all ACTs. The aim was to evaluate clinical and hormonal characteristics of FATS as well as treatment options and follow-up in the pediatric age group. Medical records of children with ACTs presenting to a single center in the last two decades were reviewed. Literature review within Pubmed revealed 34 pediatric patients (22 boys) with FAT among 192 articles. Among the 25 children presenting with ACTs in the last two decades, two new pediatric cases of FAT were identified, one benign and the other malignant, in two genders with different clinical presentations. Literature review showed that FATs are extremely rare tumors that are most commonly seen in men and boys presenting with gynecomastia. FATs are more common in children ≤8 years of age, with a median age at diagnosis of six years. While boys present with contrasexual pseudopuberty signs, girls present with isosexual pseudopuberty. A high estrogen level strongly supports diagnosis, while elevations in other adrenal hormones may be seen. FATs are usually malignant in adults and prognosis is generally very poor. However, in children approximately half are benign although assessment of malignant potential depends on clinical behavior of the tumor. FATs are very unpredictable so even after surgery long-term follow-up is required. FATs presenting in childhood may have a better prognosis than adult presentation tumors as most FATs in children are followed without recurrence of tumor. FATs are more common in children ≤8 years of age, with a median age at diagnosis of six years. FATs in childhood may have a better prognosis than in adult males.
