Meta-Analysis Review
OBJECTIVES
This systematic review and pooled analysis investigated outcomes and prognostic factors in Non-small-cell lung cancer (NSCLC) patients who underwent surgical treatment for an isolated adrenal metastasis and the primary NSCLC.
METHODS
A literature search of PubMed, Embase and Cochrane Library databases was conducted for relevant retrospective studies in patients with NSCLC and isolated adrenal metastatic lesions treated with lobectomy or pneumonectomy and adrenalectomy. Outcome measures were overall, 1-, 2- and 5-year survival rates stratified by synchronous versus metachronous adrenal metastasis and according to lymph node status, pathology and relative location of the metastasis to the primary tumour. Kaplan-Meier survival curves were generated and differences in survival were assessed by a log-rank test.
RESULTS
Thirteen studies involving 98 patients were included in this analysis. The median overall survival was 18 months, and the 1-, 2- and 5-year survival rates were 66.5, 40.5 and 28.2%, respectively. Patients with metachronous adrenal metastasis had a significantly better prognosis than patients with synchronous adrenal metastasis (P < 0.05). Patients classified as negative for lymph node metastasis had a significantly better prognosis than patients classified as positive for lymph node metastasis (P < 0.05). Pathology (squamous carcinoma versus adenocarcinoma) and the relative location of the metastasis to the primary tumour (ipsilateral adrenal metastasis or contralateral adrenal metastasis) had no significant influence on prognosis.
CONCLUSIONS
NSCLC patients with isolated adrenal metastasis undergoing surgical treatment for the primary tumour and adrenal metastasis could achieve a significant survival benefit, especially if they have metachronous adrenal metastasis or are negative for lymph node metastasis.

Meta-Analysis Review
BACKGROUND
Local treatment (metastasectomy or stereotactic radiotherapy) for oligometastatic disease (OMD) in patients with esophagogastric cancer may improve overall survival (OS). The primary aim was to identify definitions of esophagogastric OMD. A secondary aim was to perform a meta-analysis of OS after local treatment versus systemic therapy alone for OMD.
METHODS
Studies and study protocols reporting on definitions or OS after local treatment for esophagogastric OMD were included. The primary outcome was the maximum number of organs/lesions considered OMD and the maximum number of lesions per organ (i.e. 'organ-specific' OMD burden). Agreement was considered to be either absent/poor (< 50%), fair (50%-75%), or consensus (≥ 75%). The secondary outcome was the pooled adjusted hazard ratio (aHR) for OS after local treatment versus systemic therapy alone. The ROBINS tool was used for quality assessment.
RESULTS
A total of 97 studies, including 7 study protocols, and 2 prospective studies, were included. OMD was considered in 1 organ with ≤ 3 metastases (consensus). 'Organ-specific' OMD burden could involve bilobar ≤ 3 liver metastases, unilateral ≤ 2 lung metastases, 1 extra-regional lymph node station, ≤ 2 brain metastases, or bilateral adrenal gland metastases (consensus). Local treatment for OMD was associated with improved OS compared with systemic therapy alone based on 6 non-randomized studies (pooled aHR 0.47, 95% CI: 0.30-0.74) and for liver oligometastases based on 5 non-randomized studies (pooled aHR 0.39, 95% CI: 0.22-0.59). All studies scored serious risk of bias.
CONCLUSIONS
Current literature considers esophagogastric cancer spread limited to 1 organ with ≤ 3 metastases or 1 extra-regional lymph node station to be OMD. Local treatment for OMD appeared associated with improved OS compared with systemic therapy alone. Prospective randomized trials are warranted.

Meta-Analysis Review
BACKGROUND AND OBJECTIVE
Long-term opioid treatment (L-TOT) of chronic non-cancer pain (CNCP) patients has been suspected to alter the endocrine system. This systematic review and meta-analysis aimed at investigating the published evidence of L-TOT effects on the endocrine system in adult CNCP patients.
DATABASES AND DATA TREATMENT
A systematic search of the literature in MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials and the CINAHL was performed. Studies examining measures of endocrine function of the hypothalamic-pituitary-gonadal, -adrenal, -thyroid, -somatotropic and -prolactin axis in adult CNCP patients in L-TOT (≥4 weeks of use) were included. Outcomes and the level of evidence were analyzed (The Cochrane Collaboration Tool, modified version of the Newcastle-Ottawa Scale and Rating of Recommendations Assessment, Development and Evaluation working group).
RESULTS
A total of 2,660 studies were identified; 1981 excluded and finally thirteen studies (one randomized controlled trial (RCT), three longitudinal- and nine cross-sectional studies) were analyzed. L-TOT was associated with low insulin, suppression of the hypothalamic-pituitary-gonadal axis and alterations of the hypothalamic-pituitary-adrenal axis in both men and women with CNCP compared to different control groups (CNCP or healthy pain-free). No other significant differences were reported. The studies had a high risk of bias and the overall quality of evidence was low.
CONCLUSION
There seems to be an impact of L-TOT in CNCP patients on several components of the endocrine system, but the level of evidence is weak. Given the high prevalence of L-TOT use systematic studies of larger patient populations are urgently needed.
SIGNIFICANCE
This systematic review and meta-analysis suggested that long-term opioid treatment may suppress the hypothalamic-pituitary-gonadal axis, and result in lower insulin levels and alter the glucocorticoid adrenal axis in adult chronic non-cancer pain patients. This adds to the need of more research of both clinical and paraclinical outcomes and their association when initiating and maintaining long-term opioid treatment.

Pheochromocytomas and paragangliomas (PPGLs) are rare neuroendocrine tumors with heterogeneous clinical presentations and potential lethal outcomes. The diagnosis is based on clinical suspicion, biochemical testing, imaging and histopathological confirmation. Increasingly widespread use of imaging studies and surveillance of patients at risk of PPGL due to a hereditary background or a previous tumor is leading to the diagnosis of these tumors at an early stage. This has resulted in an increasing use of the term "silent" PPGL. This term and other variants are now commonly found in the literature without any clear or unified definition. Among the various terms, "clinically silent" is often used to describe the lack of signs and symptoms associated with catecholamine excess. Confusion arises when these and other terms are used to define the tumors according to their ability to synthesize and/or release catecholamines in relation to biochemical test results. In such cases the term "silent" and other variants are often inappropriately and misleadingly used. In the present analysis we provide an overview of the literature and propose standardized terminology in an attempt at harmonization to facilitate scientific communication.

Review
Adrenal incidentalomas (AIs) are incidentally discovered adrenal neoplasms. Overt endocrine secretion (glucocorticoids, mineralocorticoids, and catecholamines) and malignancy (primary or metastatic disease) are assessed at baseline evaluation. Size, lipid content, and washout characterise benign AIs (respectively, <4 cm, <10 Hounsfield unit, and rapid release); nonetheless, 30% of adrenal lesions are not correctly indicated. Recently, image-based texture analysis from computed tomography (CT) may be useful to assess the behaviour of indeterminate adrenal lesions. We performed a systematic review to provide the state-of-the-art of texture analysis in patients with AI. We considered 9 papers (from 70 selected), with a median of 125 patients (range 20-356). Histological confirmation was the most used criteria to differentiate benign from the malignant adrenal mass. Unenhanced or contrast-enhanced data were available in all papers; TexRAD and PyRadiomics were the most used software. Four papers analysed the whole volume, and five considered a region of interest. Different texture features were reported, considering first- and second-order statistics. The pooled median area under the ROC curve in all studies was 0.85, depicting a high diagnostic accuracy, up to 93% in differentiating adrenal adenoma from adrenocortical carcinomas. Despite heterogeneous methodology, texture analysis is a promising diagnostic tool in the first assessment of patients with adrenal lesions.

Review
Adrenocortical cancer (ACC) is an uncommon primary neoplasm of the adrenal cortex with dismal prognosis. It often presents with symptoms and signs of adrenal cortical hormone hypersecretion and abdominal mass effect or is incidentally detected as an adrenal mass on imaging performed for other indications. Endocrine evaluation, comprehensive staging, and meticulous resection are crucial to ensure the best possible outcome. Despite extensive initial surgical resection, local and distant metastases are not uncommon with disappointing 5-year survival, although progress is being made at high-volume centers. Accurate restaging of recurrent disease is important to guide further management. Mitotane, external beam radiation and chemotherapy, and newer anticancer systemic treatments are used as adjunctives for inoperable disease and distant metastases. Contrast-enhanced CT and MRI are first-line imaging modalities for evaluation of ACC to characterize adrenal masses and to determine tumor resectability. Emerging literature supports F-FDG PET/CT use to determine the malignant potential of adrenal masses. In patients with a diagnosis of ACC, FDG PET/CT is sensitive for detecting metastatic disease, and its tumor accumulation has been correlated to pathology, Weiss scores, and prognosis. Metomidate, labeled with C for PET or with I for SPECT/CT, allows characterization of an adrenal mass as being of adrenocortical origin with high specificity. Taking advantage of its adrenocortical avidity, metomidate has been labeled with I for radionuclide therapy in a subset of ACC. In this review, we describe how nuclear medicine imaging, and specifically PET, can assist surgical management of ACC.

OBJECTIVE
Bilateral adrenal metastases may cause adrenal insufficiency (AI) but it is unclear if screening for AI in patients with bilateral adrenal metastases is justified, despite the potential for adrenal crises.
METHOD
A search using PubMed/Medline, ScienceDirect and Cochrane Reviews was performed to collect all original research articles and all case reports from the past 50 years that describe AI in bilateral adrenal metastases.
RESULTS
Twenty studies were included with 6 original research articles, 13 case reports and one case series. The quality was generally poor. The prevalence of AI was 3-8%. Of all cases of AI (n = 25) the mean pooled baseline cortisol was 318 ± 237 nmol/L and stimulated 423 ± 238 nmol/L. Hypotension was present in 69%, hyponatremia in 9% and hyperkalemia in 100%. Lung cancer was the cause in 35%, colorectal 20%, breast cancer 15% and lymphoma 10%. The size of the adrenal metastases was 5.5 ± 2.8 cm (left) and 5.5 ± 3.1 cm (right), respectively. There was no correlation between basal cortisol, stimulated cortisol concentration or ACTH with the size of adrenal metastases. The median time to death was 5.0 months (IQR 0.6-6.5). However, two cases were alive after 12-24 months.
CONCLUSION
The prevalence of AI in patients with bilateral adrenal metastases was low. Prognosis was very poor. Due to the low prevalence of AI, screening is likely only indicated in patients with symptoms and signs suggestive of hypocortisolism.

Meta-Analysis Review
INTRODUCTION
Long-term outcome of patients with adrenal incidentaloma (AI) is unknown. The aim of this study was to systematically summarize the follow-up and outcome of clinically silent AI who do not undergo surgery.
EVIDENCE ACQUISITION
All major databases and medical literature in English-language, published from 1998 to May 2015, were systematically searched for publications on AI. Primary endpoint was hormonal hyper function; secondary endpoints were time from diagnosis to study endpoint and the outcome of adrenalectomy. Meta-analysis was performed using both qualitative and quantitative approach.
EVIDENCE SYNTHESIS
A total of 11 publications were included. Total sample size was 1298 patients. Mean follow-up duration was 44.2 months. There were 82 patients confirmed to have subclinical Cushing's syndrome at diagnosis, with 1.79% new cases at the end of follow up (95% CI, 0.002 to 0.045). Incidence of Cushing's syndrome was 0.7% (95% CI, 0.001 to 0.013) and pheochromocytoma 0.4% (95% CI, 0.001 to 0.008). The mean tumor size was 2.52cm, with mean increment of 0.03cm to 2.9cm at the end of follow up. About 3% of patients ended up with surgery (95% CI, 0.01 to 0.05) but none were due to primary adrenal malignancy. Time of greatest risk of developing Cushing's syndrome and pheochromocytoma was between months 36 and 42 (hazard rate 14%), and between months 48 and 54 (hazard rate 7%) respectively.
CONCLUSIONS
Malignant change in non-functioning AI is rare. The risk of developing overt disease over the follow-up period is low. A less stringent imaging and functional work-up interval can be considered.

Review
Immunotherapy with immune checkpoint inhibitor (ICI) monoclonal antibodies has shown to be an effective therapeutic alternative in several malignant tumors. However, adverse effects related to an activation of the immune system may accompany ICI therapy. Among the immune-related adverse events (irAEs) are autoimmune endocrine adverse effects, such as thyroiditis, and hypophysitis. Secondary adrenal insufficiency due to isolated ACTH deficiency (IAD) has also been recently reported to be associated with ICI antibodies. We carried out a systematic review of IAD cases induced by cancer immunotherapy published to date using PubMed's database. We selected 35 articles that reported 60 cancer patients diagnosed with IAD induced by ICI therapy. The prevalence was higher in men (ratio 1.6/1). Mean age at diagnosis was 63.2 ± 11.6 (range,30-87). Melanoma was the tumor most commonly reported (35%) followed by lung (28.3%) and kidney cancer (18.3%). The ICI monoclonal antibody most frequently associated was nivolumab in monotherapy (60%), followed by pembrolizumab (18.3%). Median (IQR) time to develop IAD after starting ICI therapy was 6 (4-8) months. The main symptoms at IAD diagnosis were fatigue (82.8%) and anorexia (67.2%). Hyponatremia (68%) and eosinophilia (31.8%) were the laboratory abnormalities most frequently associated with IAD. Pituitary magnetic resonance imaging (MRI) was normal in most patients (93%). Thyroiditis was the most prevalent (35%) endocrine irAE associated with IAD. In conclusion, ICI-induced IAD is a rare and potentially life-threatening condition that must be taken into account whenever treatment with immunotherapy in cancer patients is started due to their potential serious prognostic implications.

Meta-Analysis
PURPOSE
To evaluate the safety and clinical efficacy of image-guided radiofrequency ablation (RFA) in patients exhibiting adrenal metastatic tumors (AMTs).
METHODS
The PubMed, Web of Science, and Wanfang databases were searched for relevant studies published as of November 2022, and study results were pooled for subsequent analysis. The endpoints of this meta-analysis included primary and secondary technical success, local hemorrhage, pneumothorax, hypertensive crisis, local recurrence, and 1- and 3-year overall survival (OS) rates.
RESULTS
This analysis incorporated 11 studies enrolling 351 patients that underwent RFA treatment for 373 AMTs. The pooled primary and secondary technical success, local hemorrhage, pneumothorax, hypertensive crisis, local recurrence, and 1- and 3-year OS rates in these patients were 84%, 91%, 4%, 6%, 7%, 19%, 82%, and 46%, respectively. The 1-year OS ( = 75.2%, = 0.003) and 3-year OS ( = 81.4%, = 0.001) endpoints were subject to significant heterogeneity. Subgroup analyses suggested that primary technical success rates were < 80% in patients with tumors exhibiting a mean diameter ≥ 4 cm. Guidance type and tumor size had no impact on a hypertensive crisis or local recurrence rates.
CONCLUSIONS
These data indicate that image-guided RFA represents a safe and effective means of treating AMTs.
