BACKGROUND: Adrenocortical carcinoma (ACC) is rare and an aggressive tumour. Mitotane is the mainstay adjuvant drug in treating ACC. The study aimed to describe patients diagnosed with precocious puberty (PP) and other endocrinological complications during mitotane therapy.
METHODS: This retrospective study enrolled 4 patients with ACC treated with mitotane therapy complicated by PP. We analysed clinical manifestations, radiological, histopathological findings, and hormonal results.
RESULTS: The median age at the diagnosis of ACC was 1.5 years. All patients were treated with surgery and mitotane, accompanied by chemotherapy regimens in 2 cases. The median time from surgery to the initiation of mitotane therapy was 26 days. During mitotane treatment, PP was confirmed based on symptoms, and hormonal and imaging tests. In one patient, incomplete peripheral PP was followed by central PP. The median time from the therapy initiation to the first manifestations of PP was 4 months. Additionally, due to mitotane-induced adrenal insufficiency, patients required a supraphysiological dose of hydrocortisone (HC), and in one patient, mineralocorticoid (MC) replacement with fludrocortisone was necessary. In 2 patients, hypothyroidism was diagnosed. All patients presented neurological symptoms of varying expression, which were more severe in younger children.
CONCLUSIONS: The side effects of using mitotane should be recognized quickly and adequately treated. In prepubertal children, PP could be a complication of therapy. The need to use supraphysiological doses of HC, sometimes with MC, should be highlighted. Some patients require levothyroxine replacement therapy. The neurotoxicity of mitotane is a significant clinical problem.
UNASSIGNED: Rak kory nadnerczy (ACC) jest rzadkim i agresywnym nowotworem. Mitotan jest podstawowym lekiem w terapii uzupełniającej ACC. Celem pracy była ocena pacjentów z rozpoznaniem przedwczesnego dojrzewania płciowego (PP) oraz innych powikłań endokrynologicznych w trakcie leczenia mitotanem.
UNASSIGNED: Do retrospektywnego badania włączono 4 pacjentów, u których w trakcie terapii mitotanem zdiagnozowano PP. W pracy przeanalizowano objawy kliniczne, wyniki badań endokrynologicznych radiologicznych i histopatologicznych.
UNASSIGNED: Mediana wieku w momencie rozpoznania ACC wynosiła 1,5 roku. Wszyscy pacjenci byli leczeni operacyjnie z następową terapią mitotanem, w dwóch przypadkach zastosowano również chemioterapię. Mediana czasu od operacji do rozpoczęcia leczenia mitotanem wyniosła 26 dni. Podczas terapii PP potwierdzono na podstawie objawów, badań hormonalnych i obrazowych. U jednego pacjenta po niepełnym obwodowym PP wystąpiło centralne PP. Mediana czasu od rozpoczęcia terapii do wystąpienia pierwszych objawów PP wyniosła 4 miesiące. Dodatkowo, z powodu niedoczynności kory nadnerczy wywołanej mitotanem, chorzy wymagali ponad fizjologicznych dawek hydrokortyzonu (HC), a u jednego pacjenta konieczna była suplementacja mineralokortykoidów (MC). U dwóch pacjentów rozpoznano niedoczynność tarczycy. Wszyscy pacjenci prezentowali objawy neurologiczne o różnym nasileniu, poważniejsze u młodszych dzieci.
UNASSIGNED: Skutki uboczne stosowania mitotanu powinny być szybko rozpoznane i odpowiednio leczone. U dzieci przed okresem dojrzewania PP może być powikłaniem terapii. Należy zwrócić uwagę na konieczność stosowania ponadfizjologicznych dawek HC, czasem z MC. Niektórzy pacjenci wymagają terapii substytucyjnej lewotyroksyną. Poza endokrynologicznymi objawami ubocznymi istotnym problemem klinicznym jest neurotoksyczność mitotanu.

Adrenocortical carcinoma (ACC) is a rare malignant tumor originating in the adrenal cortex and characterized by poor 5-year survival. It occurs with a frequency of 2-4 cases per 2 million in the population. Women are more frequently affected than men and it is mostly detected in the fourth and fifth decades. In the most of cases, the cancerogenesis occurs sporadically because of gene driver mutations in somatic adrenocortical cells, in other cases it can be found as part of a genetically determined syndrome such as Li-Fraumeni syndrome or Wermer\'s syndrome (multiple endocrine adenomatosis type I). ACC most frequently happens occurs without symptoms in the initial stages leading to poor diagnoses. Because of this lack of early detection, the tumor is not considered malignant reducing the benefits of further treatment. Sometimes the fact that the resected tumor is indeed adrenocortical carcinoma becomes clear only after recurrence, or after the appearance of metastases. We present a case of adrenocortical carcinoma in a 46-year-old woman who went to the doctor in 1.5 year after symptoms were manfested. This clinical case illustrates the consequences of late diagnosis of a malignant tumor. We would like to emphasize the importance of timely detection of a neoplasm, using all of the potential of laboratory-instrumental and genomic analysis. Due to low oncological awareness, our patient was slow to seek medical help, which in turn led not only to metastases, but also to complications in the cardiovascular system.
Адренокортикальный рак (АКР) – редкая злокачественная опухоль коры надпочечников c распространенностью 0,5–2 случая на 1 млн населения, характеризующаяся неблагоприятным прогнозом, низкой 5-летней выживаемостью пациентов, поздним сроком выявления и агрессивностью клинического течения. Заболевание чаще встречается среди женщин (1,5:1 или 55–60%), средний возраст на момент постановки диагноза – 40–50 лет. Клинические проявления АКР в большинстве случаев отсутствуют, что является причиной поздней диагностики заболевания. В некоторых случаях АКР диагностируется при рецидиве заболевания после хирургического лечения гормонально-неактивной опухоли надпочечника или на этапе метастазирования. АКР может быть гормонально-активной опухолью, являясь причиной гиперкортицизма/вирильного синдрома и др. Канцерогенез АКР обусловлен как спонтанно возникающими мутациями в соматических клетках коры надпочечников, так и генетическими поломками в рамках того или иного наследственного синдрома, например Ли–Фраумени и Вермера (синдром множественных эндокринных неоплазий 1-го типа). В статье приведен клинический случай, иллюстрирующий последствия поздней диагностики АКР у женщины 46 лет, которая обратилась за медицинской помощью через 1,5 года после развития манифестных симптомов с клиникой вирильного синдрома в сочетании с артериальной гипертензией, инвазией левой почечной вены и распространением опухолевого тромба в просвет нижней полой вены по данным мультиспиральной компьютерной томографии. Данный клинический случай подчеркивает важность онконастороженности и своевременной диагностики АКР с помощью лабораторно-инструментальных и генетических методов.

Li-Fraumeni syndrome (LFS) is a cancer predisposition syndrome associated with a high, lifetime risk of a broad spectrum of cancers caused by pathogenic germline TP53 mutations. Numerous different germline TP53 mutations have been associated with LFS, which has an exceptionally diverse clinical spectrum in terms of tumor type and age of onset. Our patient has developed six asynchronous tumors to date: a phyllode tumor of the breast, a pheochromocytoma, a rosette-forming glioneuronal tumor (RGNT), an adrenocortical carcinoma (ACC), a ductal carcinoma of the breast, and a thymoma. The occurrence of such a number of rare tumors is sporadic even among in the population of patients living with cancer predisposition syndromes. In this instance, the omission of pretest genetic counseling and thorough family tree analysis prior to selecting the test led to the oversight of an underlying TP53 likely pathogenic mutation (classified as Class 4). This emphasizes the necessity for such counseling to prevent overlooking crucial genetic information. Neglecting this step could have had profound implications on the patient\'s treatment, particularly considering the early onset and occurrence of multiple tumors, which typically raise suspicion of a hereditary component. The implications for family members must be considered.

Ectopic adrenocorticotropic hormone syndrome (EAS) is a rare condition caused by pancreatic neuroendocrine tumors (p-NETs). The severe hypercortisolemia that characterizes EAS is associated with a poor prognosis and survival. Mitotane is the only adrenolytic drug approved by the Food and Drug Administration and is often used to treat adrenocortical carcinoma. Combination therapy with mitotane and other adrenal steroidogenesis inhibitors is common for patients with Cushing\'s syndrome (CS). Here, we describe three patients who developed EAS secondary to the liver metastasis of p-NETs. All three rapidly developed hypercortisolemia but no typical features of CS. They underwent anti-tumor and mitotane therapy, which rapidly reduced their blood cortisol concentrations and ameliorated their symptoms. Their hypercortisolemia was controlled long term using a low dose of mitotane. The principal adverse effects were a slight loss of appetite and occasional dizziness, and there were no severe adverse effects. Importantly, even when the tumor progressed, the patients\' circulating cortisol concentrations remained within the normal range. In summary, the present case series suggests that mitotane could be used to treat hypercortisolemia in patients with EAS caused by advanced p-NETs, in the absence of significant adverse effects.

A 57-year-old woman was diagnosed with adrenocortical carcinoma. Following the adrenalectomy, she underwent adjuvant radiation and mitotane therapy; however, liver metastases were observed. Repeated radiofrequency ablation (RFA) was performed for liver metastases. In addition, a multidisciplinary approach combining systemic chemotherapy, radiotherapy, and surgery was used for lung and distant lymph node metastases that arose during the course of treatment. Notably, 49 months have passed since the adrenalectomy and 36 months since the recurrence of the liver metastases, and the patient remains on multidisciplinary therapy. Thus, RFA for liver metastasis of adrenocortical carcinoma may be an effective component of a multidisciplinary treatment.

The areal distributions of the soil organochlorine pesticide (OCP) levels were investigated at adjacent and surrounding sites of the obsolete pesticide stockpile warehouse in Kocaeli, Türkiye. OCP levels in soil at neighboring sampling locations (positioned at 0.4 to 3 km from the stockpile) varied from 0.4 to 9 µg/kg and 4.2 to 2226 µg/kg (dry weight) for ΣHCHs and ΣDDXs, respectively. Levels at adjacent locations (positioned within 20 m from the stockpile) were considerably higher, varying from 74 to 39,619 µg/kg and 1592 to 30,419 µg/kg for ΣHCHs and ΣDDXs, respectively. Levels of OCPs dropped abruptly with the horizontal distance from the stockpile and had different transect profiles. The enantiomer fractions (EFs) near the stockpile range from 0.494 to 0.521, 0.454 to 0.515, and 0.483 to 0.533 for α-HCH, o,p\'-DDT, and o,p\'-DDD, respectively. These near-racemic EFs suggested that observed soil OCP levels were mainly influenced by recent emissions from the stockpile. A comparison of OCP compositions observed in the soil at the present study with the technical HCHs and DDTs revealed that the material in the stockpile primarily contains byproducts that were discarded during DDT and Lindane production at the adjacent plant instead of their technical mixtures.

Adrenocortical carcinoma (ACC) is a rare malignancy with a poor prognosis and limited treatment options for metastases. However, new effective regimens are emerging for specific conditions in metastatic ACC.
We report a case of a 36-year-old man diagnosed with metastatic ACC who had a large left adrenal mass (158 mm × 112 mm) and multiple metastases in the liver and lungs. Genetic testing revealed a microsatellite instability-high (MSI-H) tumor, a splice mutation in MLH1, and a high tumor mutational burden (TMB). After the left adrenalectomy, he received sequential treatment with a combination of mitotane, etoposide, paraplatin (EP-M), and sintilimab. His condition has been assessed as a stable disease since the sixth cycle of the combined regimen.
This case highlights the remarkable response of our patient\'s ACC with MSI-H tumor, MLH1 spice mutation, and high TMB to treatment with a novel combination of EP-M and sintilimab. Our findings suggest a promising therapeutic option for patients with similar molecular profiles.

Metastatic adrenocortical carcinoma (ACC) often has a poor outcome, with a five-year survival of less than 25%. We report a rare case of metastatic ACC with a myxoid variant with chromothripsis. We review the histologic variants of ACC, including myxoid type, molecular drivers, and current and investigational therapies for adrenocortical carcinoma. We also discuss the mechanism of chromothripsis, chromothripsis in ACC tumorigenesis, and propose potential therapies targeting chromothripsis.

Adrenocortical carcinoma (ACC) is a rare type of cancer that is associated with a high rate of recurrence and poor prognosis. The main diagnostic approaches to adrenocortical cancer include CT scan, MRI and the promising role of 18F-FDG PET/CT. The main therapeutic approaches include radical surgery of local disease and recurrences, as well as adjuvant mitotane therapy. The evaluation of adrenocortical carcinoma (ACC) could be difficult by using 18F-FDG PET/CT in view of the significant association between the 18F-FDG uptake and ACC. At the same time, not all adrenal glands with 18F-FDG uptake are considered to be malignant, so awareness of these various findings is substantial for ACC management, especially with limited data regarding the role of 18F-FDG PET/CT in ACC post-operative settings. This report discusses the case of a 47-year-old man with a history of left adrenocortical carcinoma who underwent adrenalectomy and received adjuvant mitotane therapy. 9 months after the surgery, a follow-up 18F-FDG PET/CT scan showed that the 18F-FDG uptake was prominent in the right adrenal gland without corresponding abnormal CT scan findings.

Adrenocortical carcinoma (ACC) is a rare, heterogeneous, and aggressive malignancy with a generally poor prognosis. Surgical resection is the optimal treatment plan. After surgery, both mitotane treatment or the etoposide-doxorubicin-cisplatin (EDP) protocol plus mitotane chemotherapy have a certain effect, but there is still an extremely high possibility of recurrence and metastasis. The liver is one of the most common metastatic targets. Therefore, techniques such as transcatheter arterial chemoembolization (TACE) and microwave ablation (MWA) for liver tumors can be attempted in a specific group of patients. We present the case of a 44-year-old female patient with primary ACC, who was diagnosed with liver metastasis 6 years after resection. During mitotane treatment, we performed four courses of TACE and two MWA procedures in accordance with her clinical condition. The patient has maintained the partial response status and has currently returned to normal life to date. This case illustrates the value of the practical application of mitotane plus TACE and MWA treatment.
