Comparison of Nausea and Vomiting Associated With Amino Acid Formulations Coinfused With Peptide Receptor Radionuclide Therapy: Commercial Parenteral Nutrition Formulas Versus Compounded Arginine/Lysine.

OBJECTIVES: Positively charged amino acids (AA) such as arginine/lysine are coinfused with radiolabeled somatostatin analogs to reduce rates of nephrotoxicity. In the phase 3 NETTER-1 trial, commercial AA formulations were used in association with 177Lu-DOTA-0-Tyr3-Octreotate (DOTATATE). These formulations were also used in an early-access program (EAP) before regulatory approval of 177Lu-DOTATATE. Our program transitioned to compounded l-arginine 2.5%/l-lysine 2.5% in 0.9% NaCl after commercial approval of 177Lu-DOTATATE. We sought to compare rates of nausea/vomiting with arginine/lysine versus commercial parenteral AA formulations. METHODS: Rates of nausea/vomiting of all 20 EAP patients who received commercial AAs (15% Clinisol) were compared with the first 29 patients to receive 177Lu-DOTATATE after commercial approval and coinfused with arginine/lysine. Other parameters reviewed included infusion rates, need for PRN nausea medications, and other toxicities. RESULTS: Seventeen percent of patients who received compounded arginine/lysine experienced nausea, compared with 100% of patients in the EAP group (P < 0.0001). Infusion-related reactions occurred in 3% of the arginine/lysine cohort versus 35% in the EAP group. Infusion durations were substantially shorter in the arginine/lysine cohort (reduced by 61%). CONCLUSIONS: Coinfusions of arginine/lysine with radiolabeled somatostatin analogs result in substantially lower rates of nausea/vomiting compared with commercial AA formulations designed for parenteral nutrition.

Development and characterization of octreotide-modified curcumin plus docetaxel micelles for potential treatment of non-small-cell lung cancer.

We prepared octreotide (OCT)-modified curcumin plus docetaxel micelles to enhance active targeting and inhibit tumor metastasis by destroying vasculogenic mimicry (VM) channels. Soluplus was applied as an amphiphilic material to form micelles via film dispersion. The cytotoxic effects, active cellular targeting, and inhibitory effects on metastasis were systematically evaluated in vitro using A549 cells, and in vivo antitumor effects were evaluated using xenograft tumor-bearing mice. In vitro assays indicated that the OCT-modified curcumin plus docetaxel micelles showed robust cytotoxicity on A549 cells and effectively inhibited VM channels and tumor metastasis. Studying the mechanism of action indicated that OCT-modified curcumin plus docetaxel micelles downregulated MMP-2 and HIF-1α. In vivo assays indicated that OCT-modified curcumin plus docetaxel micelles increased drug accumulation at tumor sites and showed obvious antitumor efficacy. The developed OCT-modified curcumin plus docetaxel micelles may offer a promising treatment strategy for non-small-cell lung cancer.

Successful Management of a Child With Drug-induced Necrotizing Pancreatitis During Acute Lymphoblastic Leukemia Therapy: A Case Report.

Acute pancreatitis in children acute lymphoblastic leukemia is commonly caused by drugs, for example, L-Asparaginase, pegapargase, steroids. The incidence of this complication is estimated at 6.7% to 18%. Although the majority of drug-induced acute pancreatitis cases are mild, severe cases can rarely occur. This work presents a case of successful management of a child with drug-induced necrotizing pancreatitis during acute lymphoblastic leukemia therapy. This case illustrates that comprehensive care and immediate intensive treatment can rescue patient despite poor prognosis. Administration of octreotide may serve a role in limiting the severity of the disease.

Management of Well-differentiated Gastroenteropancreatic Neuroendocrine Tumors (GEPNETs): A Review.

PURPOSE: Neuroendocrine tumors (NETs) are heterogeneous tumors that arise from the neuroendocrine cells of the digestive tract and other organs, such as the lung, ovary, and thyroid glands. They can be well differentiated or poorly differentiated, and management of these tumors differs for each histologic subtype. We have performed a review of NETs and focused on management of well-differentiated gastroenteropancreatic neuroendocrine tumors (GEPNETs) and carcinoid syndrome. METHODS: A PubMed search was performed to obtain articles on the management of well-differentiated NETs. Using the key words neuroendocrine tumors, carcinoid, pNET, octreotide, somatostatin analogues, and radiolabeled therapy, we reviewed Phase II and III trials that were published over the past 30 years. We also reviewed guidelines from the European Neuroendocrine Tumor Society, North America Neuroendocrine Tumor Society, and National Comprehensive Cancer Network in our search. FINDINGS: NETs are usually slow-growing tumors that remain asymptomatic for a long duration and can be either nonfunctioning or functioning. Surgical resection is recommended for locoregional disease, impending obstruction, symptom control, and advanced disease. Nonsurgical treatment options include somatostatin analogues (SSAs), multikinase inhibitors, targeted therapy, chemotherapy, and radiolabeled SSAs. Carcinoid syndrome is mainly treated with SSAs. IMPLICATIONS: Although GEPNETs are slow-growing tumors, most patients are diagnosed with metastatic disease, and therefore it is important that the management of each patient be discussed in a multidisciplinary setting to optimize the treatment strategy. Patients should be considered for clinical trials and refractory cases referred to a specialty center.

The effect of co-administration of Lawsonia inermis extract and octreotide on experimental hepatocellular carcinoma.

OBJECTIVES: To investigate the effect of Lawsonia inermis total methanolic extract (LIE) and octreotide (OC) on hepatocellular carcinoma (HCC) progression, depending on somatostatin receptor 2 (SSTR-2) and Alfa fetoprotein (AFP) perturbations. METHODS: Sixty albino mice, divided into five groups (12/each); all except control were injected with single diethyl nitrosamine (DENA) dose of 90 mg/kg body weight, intraperitoneally (IP). DENA group was killed at the last day of week 18. LIE group was given 200 mg/100 ml drinking water from first day of DENA injection until end of week 18. OC group received OC (0.1 mg/kg body weight, twice daily by subcutaneous injection, SC from the first day of week 17 till end of week 18. LIE + OC was given medications till the last day of week 18. Serum AFP, liver tissue SSTR-2 mRNA, its protein expression, reduced glutathione (GSH) and malondialdehyde (MDA) were analyzed. RESULTS: A significant increase in plasma AFP and hepatic mRNA, associated to liver tissue neoplastic changes, SSTR-2 expression and MDA with decreased hepatic GSH were observed in DENA group. These changes were significantly improved by LIE and/or OC. CONCLUSIONS: LIE and/or OC treatment has effective chemopreventive action due to their ability to alleviate oxidative stress, desensitizing cellular growth receptor to SST.

Individualized dosimetry-based activity reduction of 9°Y-DOTATOC prevents severe and rapid kidney function deterioration from peptide receptor radionuclide therapy.

PURPOSE: Assessment of kidney function evolution after (90)Y-DOTATOC peptide receptor radionuclide therapy (PRRT) with capped activity administration based on a 37-Gy threshold of biological effective dose (BED) to the kidney. METHODS: In a prospective phase II study, patients with metastasized neuroendocrine tumours were evaluated for therapy using 185 MBq (111)In-pentetreotide with amino acid coinfusion. Planar whole-body images were acquired at four time-points after injection and kidney volumes were measured using CT/MRI. BED to the kidneys was estimated using an extended BED formula and biexponential renal clearance. Based on published BED dose-toxicity relationships, we allowed a maximal kidney BED of 37 Gy; if the calculated BED exceeded 37 Gy, treatment activity was reduced accordingly. Kidney function was assessed at baseline and at 18 months, predominantly using (51)Cr-EDTA. The rate of renal function decline was expressed as annual glomerular filtration rate loss (aGFRL). RESULTS: Only 22 of 50 patients reached the 18-months time-point, with most missing patients having died due to disease progression. In the 22 patients who reached 18 months, no rapid kidney function deterioration was observed over the 18 months, aGFRL >33% was not seen, and only three patients showed an increase of one toxicity grade and one patient an increase of two grades. No significant correlations between kidney volume (p = 0.35), baseline GFR (p = 0.18), risk factors for renal function loss (p = 0.74) and aGFRL were observed. Among the 28 patients who did not reach 18 months, one developed grade 4 kidney toxicity at 15 months after PRRT. CONCLUSION: Prospective dosimetry using a 37 Gy BED as the threshold for kidney toxicity is a good guide for (90)Y-DOTATOC PRRT and is associated with a low risk of rapid renal function deterioration and evolution to severe nephrotoxicity.

Chylous ascites after liver transplant: case report and review of literature.

CASE: A 62-year-old man with cirrhosis, hepatitis C, and hepatocellular carcinoma, underwent a liver transplant. On day 11 after surgery, a chylous leak from a partial wound dehiscence was noted. The leak did not respond to 2 weeks of uninterrupted, fat-free clear liquid diet and 12-hour total parenteral nutrition at night. The same treatment was continued for another 6 weeks with fatty meal challenge every weekend, which he failed. He was then given a fat-free clear liquid diet, 24-hour total parenteral nutrition, and octreotide 100 µg subcutaneously every 8 hours for 14 days. A prompt response was noted. His recovery was excellent at the time of this writing (9 months' follow-up). DISCUSSION: Eleven major cases have been reported with 9 cases being managed conservatively. Four were given a diet plus total parenteral nutrition without octreotide producing a cure in 3 to 36 days. Two cases (including ours) were given the diet and total parenteral nutrition, which failed; octreotide was then added, and these cases were cured in 2 to 4 weeks. Therefore, diet with total parenteral nutrition failed in 33.3% of the cases (2/6). In 3 cases, octreotide was used from the outset. They were all cured in ≤ 2 weeks. One case was operated on for peritonitis; chylous ascites was found and a leak was ligated. One patient with congenital lymphatic disorder underwent peritoneovenous shunting. Octreotide was not used in any of the cases of chylous ascites that were treated surgically. CONCLUSIONS: If exploratory surgery is done for any other reason, it is best to identify a chylous leak and ligate it. Otherwise, we recommend octreotide combined with a fat-free, clear liquid diet, and supplementation with medium chain triglycerides and total parenteral nutrition from the outset.

Effect of growth hormone on dawn phenomenon in patients with type 2 diabetes.

We aimed to investigate the involvement of growth hormone in dawn phenomenon and insulin sensitivity in patients with type 2 diabetes mellitus (T2DM). On six occasions separated by intervals of at least 3 days, subjects received early evening (16:00 hours) or late night (23:00 hours) pretreatment with subcutaneous injection of normal saline, human growth hormone, or octreotide. Modified euglycemic insulin clamp test was done 16 hours later and variable glucose infusion (M values) was determined. Plasma glucose, serum insulin, insulin-like growth factor-1, non-esterified fatty acids, and metabolic clearance rate of insulin (MCRI) were measured. Early evening application of growth hormone decreased MCRI 16 hours later, suggesting reduction in insulin sensitivity. Exogenous growth hormone injection reduced insulin sensitivity in T2DM patients. Results provide direct evidence for the role of growth hormone in regulating the insulin sensitivity in insulin-resistant patients.

Synthesis and evaluation of biodegradable PCL/PEG nanoparticles for neuroendocrine tumor targeted delivery of somatostatin analog.

PURPOSE: Neuroendocrine tumors often present a diagnostic and therapeutic challenge. We have aimed to synthesize and develop biodegradable nanoparticles of somatostatin analogue, octreotide for targeted therapy of human neuroendocrine pancreatic tumor. METHODS: Direct solid phase peptide synthesis of octreotide was done. Octreotide loaded PCL/PEG nanoparticles were prepared by solvent evaporation method and characterized for transmission electron microscopy, differential scanning calorimetery (DSC), Zeta potential measurement studies. The nanoparticles were evaluated in vitro for release studies and peptide content. For biological evaluations, receptor binding & cytotoxicity studies were done on BON-1 neuroendocrine tumor cell line. Biodistribution of radiolabeled peptide and nanoparticles, tumor regression studies were performed on tumor-bearing mouse models. RESULTS: We have synthesized and purified octreotide with the purity of 99.96% in our laboratory. PEG/PCL nanoparticles with an average diameter of 130-195 nm having peptide loading efficiency of 66-84% with a negative surface charge were obtained with the formulation procedure. Octreotide nanoparticles have a negative action on the proliferation of BON-1 cells. In vivo biodistribution studies exhibited major accumulation of octreotide nanoparticles in tumor as compared to plain octreotide. Octreotide nanoparticles inhibited tumor growth more efficiently than free octreotide. CONCLUSIONS: Thus, it was concluded that the PCL/PEG nanoformulation of octreotide showed high tumor uptake due to the enhanced permeation and retention (EPR) effect and then peptide ligand imparts targetability to the sst2 receptor and there by showing increase tumor growth inhibition. Selective entry of nanoparticles to the tumor also give the reduce side effects both in vivo and in vitro.

The Di Bella Method (DBM) improved survival, objective response and performance status in a retrospective observational clinical study on 55 cases of lymphomas.

OBJECTIVES: Lymphomas are the main form of haematological neoplasms, representing 55.6% of all tumours of the blood. Overall, they account for 5.3% of all malignant tumours (excluding basal and squamous cell skin cancer) in Italy with a prevalence constantly increasing at a rate of 3% per year. From a histological point of view, they represent a vast heterogeneous group of haematological diseases, their staging being based on defined cyto-morphological and anatomo-pathological criteria. Although the combined use of standard approaches can provide good response rates, recurrence is particularly frequent in patients undergoing traditional treatment, with critical and often irreversible side effects such as myelosuppression and a high frequency of opportunistic infections and sterility. Numerous epidemiological studies and preclinical data have for some time now reported the anticancer effects of molecules such as Melatonin, Retinoids, Vitamins E, D3, and C, Somatostatin and prolactin inhibitors in neoplastic diseases. There are, however, very few publications on the combined effects of these substances in vivo. METHODS: We report an observational study carried out on 55 patients affected by various forms of lymphoma, treated with the biological therapy known as the Di Bella Method (DBM). The 1, 3 and 5-year survival rates are reported, together with any signs of toxicity. RESULTS: The DBM treatment achieved partial or complete objective responses in a shorter time and in greater percentages if administered as first-line therapy. The adjuvant treatment increased survival time and improved quality of life with respect to the data reported in the literature for the same types and stages of lymphoma. CONCLUSION: Overall, the treatment was well tolerated, with minor and transient side effects. The patients were able to continue the treatment at home, carrying out their normal activities without problems.

Randomized trial of tamoxifen versus combined tamoxifen and octreotide LAR Therapy in the adjuvant treatment of early-stage breast cancer in postmenopausal women: NCIC CTG MA.14.

PURPOSE: Somatostatin analogs act directly on breast cancer cells and indirectly on insulin and insulin-like growth factor 1 (IGF-1) levels. This trial was undertaken to assess whether octreotide would lower insulin and IGF-1 levels and reduce risk of breast cancer recurrence. PATIENTS AND METHODS: The NCIC CTG MA.14 (NCIC Clinical Trials Group MA.14) trial randomly assigned postmenopausal women to 5 years of tamoxifen 20 mg daily (TAM) or TAM plus 2 years of octreotide 90 mg depot intramuscular injections monthly (TAM-OCT) as adjuvant therapy. The primary end point was event-free survival (EFS). Secondary end points were relapse-free survival (RFS), overall survival (OS), toxicity, and effects of treatment on IGF physiology. RESULTS: Among 667 women with a median follow-up of 7.9 years, 220 events occurred-108 with TAM-OCT and 112 with TAM. Adjusted hazard ratios (HRs; TAM-OCT to TAM) were 0.93 for EFS (95% CI, 0.71 to 1.22; P = .62), 0.84 for RFS (95% CI, 0.59 to 1.18; P = .31), and 0.97 for OS (95% CI, 0.69 to 1.37; P = .86). Among patients with normal baseline gallbladder imaging, cholecystectomy was required in 23.0% of those receiving TAM-OCT but in only 1.4% of those receiving TAM (P < .001). At 4 months, TAM-OCT had significantly (P < .001) lowered IGF-1, IGF binding protein 3, and C-peptide levels. Older age (P = .02), tumor size (P = .001), nodal status (P = .01), high C-peptide levels (P < .001), and higher body mass index (BMI) in models excluding C-peptide (P < .001) were associated with poorer EFS in multivariate analysis. CONCLUSION: Octreotide-related changes in circulating IGF-1 and C-peptide levels were statistically significant. Octreotide did not add significant clinical benefit. High C-peptide levels (surrogate for insulin secretion rate) and high BMI were associated with poor outcome.

Oxidative stress and ERK1/2 phosphorylation as predictors of outcome in hepatocellular carcinoma patients treated with sorafenib plus octreotide LAR.

We reported a relevant activity of the combination between sorafenib and octreotide long-acting release (LAR) in advanced hepatocellular carcinoma (HCC) patients. In this work, we have studied if oxidative stress in both serum and peripheral blood mononuclear cells (PBMC) and pERK activation status in PBMC could be predictive of response. In the 20 responsive patients, the decrease of reactive oxygen species levels was already detectable after 10 days (T10) from the beginning of sorafenib administration, and this effect was enhanced by the combined treatment with sorafenib+octreotide LAR (T21). This effect correlated with the modulation of superoxide dismutase (SOD) activity (physiological scavenger of O(2-)) and of serum nitric oxide (NO) levels. Sorafenib alone induced an increase of about 40% of NO levels and of about two-fold of SOD activity in responsive patients, and both effects were significantly potentiated by the combined treatment. We found a gradual reduction of Erk1/2 activity, as evaluated by cytofluorimetric analysis, in 15 responsive patients reaching about 50% maximal decrease at T21. On the other hand, in 17 resistant patients, Erk1/2 activity was about 80% increased at T21. The determination of both the oxidative stress status and pERK activity in PBMC has high value in the prediction of response to sorafenib+octreotide therapy in HCC patients.

[Influence of prolonged treatment with octreotide on GH, IGF I, insulin, ACTH, cortisol, T3, T4 and TSH secretion in a case of congenital chylothorax]. / Influenza del trattamento prolungato con octreotide sulla secrezione di GH, IGFI, insulina, ACTH, cortisolo, T3, T4 e TSH in un caso di chilotorace congenito.

Congenital chylothorax is a rare condition characterized by the accumulation of lymph fluid in the pleural space that causes respiratory and circulatory dysfunctions, immune deficiencies, hypoalbuminemia, electrolyte imbalance and alterations of the coagulation. Mortality rates are elevated and can rise to 50%. Therapy consists in conservative treatment based on thoracic drainage combined with total parenteral nutrition or use of low-fat high-protein diet supplemented with medium chain triglycerides. In case of failure surgical intervention may be considered. During the last years some authors have experienced the use of octreotide with doubtful results. In no case the drug impact on insulin, GH and cortisol secretion in neonatal age has been investigated and only in one case the effect on thyroid hormones has been assessed. We report the case of a 36-week baby with congenital chylothorax treated with octreotide for 42 days. The drug was well tolerated but hormonal level measurements showed a deep depression of insulin secretion unaccompanied by alterations of glucose levels. Levels of GH and TSH showed only a transitory decrease. ACTH and cortisol remained normal. At 5 months, the measurements of hormonal levels did not show significant alterations. It is not possible to determine if such a drug played an essential role in the solution of the pleural effusion, but it is important to emphasize that a prolonged treatment with octreotide has not caused, in our case, persistent hormonal alterations.

Growth hormone-releasing hormone activates sleep regulatory neurons of the rat preoptic hypothalamus.

We examined whether growth hormone-releasing hormone (GHRH) may promote non-rapid eye movement (NREM) sleep via activation of GABAergic neurons in the preoptic area. Male Sprague-Dawley rats were implanted with EEG, EMG electrodes and a unilateral intracerebroventricular cannula. Groups of rats received injections (3 microl icv) with gonadotropin-releasing hormone (GHRH) (0.1 nmol/100 g body wt) or equal volume of physiological saline at the onset of the dark period and were permitted spontaneous sleep for 90 min. Separate groups of rats were sleep deprived by gentle handling for 90 min, beginning at the time of GHRH or saline injection, at the onset of the dark period. Other groups of rats received intracerebroventricular octreotide (somatostatin analog OCT) injections, intracerebroventricular injection of one of two doses of competitive GHRH antagonist, or intracerebroventricular saline injection at light onset and were then permitted 90 min spontaneous sleep-waking. Rats were killed immediately after the 90-min sleep/wake monitoring period. Brain tissue was processed for immunohistochemistry for c-Fos protein and glutamic acid decarboxylase (GAD). Single c-Fos and dual Fos-GAD cell counts were determined in the median preoptic nucleus (MnPN), and in the core and the extended parts of the ventrolateral preoptic nucleus (cVLPO and exVLPO). Intracerebroventricular GHRH elicited a significant increase in NREM sleep amount. Double-labeled Fos+GAD cell counts were significantly elevated after GHRH injection in the MnPN and VLPO in both undisturbed and sleep-deprived groups. OCT and GHRH antagonist significantly decreased NREM sleep amount compared with control rats. OCT injection increased single c-Fos-labeled cell counts in the MnPN, but not in the VLPO. Double-labeled cell counts were significantly reduced after OCT and the high dose of GHRH antagonist injection in all areas examined. These findings identify GABAergic neurons in the MnPN and VLPO as potential targets of the sleep-regulatory actions of GHRH.

Sorafenib plus octreotide is an effective and safe treatment in advanced hepatocellular carcinoma: multicenter phase II So.LAR. study.

PURPOSE: Advanced hepatocellular carcinoma (HCC) not eligible for local therapies has limited chances of cure. Sorafenib is a multikinase inhibitor with proven activity in advanced HCC. Octreotide is used in this setting with conflicting results. Treatment with sorafenib and long-acting octreotide was tested in advanced HCC to evaluate safety and activity. METHODS: Fifty patients with advanced HCC, Child-Pugh A or B, received sorafenib at a dosage of 800 mg/day for 28 days with a following week of rest and long-acting octreotide at a dose of 40 mg, administered every 28 days. RESULTS: All patients were assessable for safety and efficacy. Sixteen patients out of 50 (34%) were naïve from other therapies, while all the others were previously treated with local and/or systemic treatments. We achieved 5 partial responses (10%), 33 stable diseases (66%) and 12 progressions of disease (24%). Median time to progression was 7.0 months (95% CI, 3.0-10.9 months), and median overall survival was 12 months (95% CI, 6.3-17.4 months). Treatment was well tolerated. Diarrhoea (6%) and hypertension (4%) were the most frequent grade 3 toxicities. CONCLUSIONS: Our data suggest that the combination between sorafenib and long-acting octreotide is active and well tolerated in patients with advanced HCC and could represent another efficacious chance for the management of this population.

From somatostatin to octreotide LAR: evolution of a somatostatin analogue.

BACKGROUND: Acromegaly is characterized by overproduction of growth hormone (GH) by the pituitary gland. GH stimulates the synthesis of insulin-like growth factor-I (IGF-I), and the somatic growth and metabolic dysfunction that characterize acromegaly are a consequence of elevated GH and IGF-I levels. Gastroenteropancreatic neuroendocrine tumors (GEP-NETs) are rare, slow-growing neoplasms that have usually metastasized by the time of diagnosis. The majority of GEP-NETs are carcinoid tumors whose syndrome is caused by the hypersecretion of biogenic amines, peptides and polypeptides responsible for the principal symptoms of diarrhea and flushing. METHODS: The MEDLINE and EMBASE databases were searched for preclinical and clinical studies of octreotide (Sandostatin* ), a potent synthetic somatostatin analogue, in patients with acromegaly or GEP-NETs. OBJECTIVE: This article reviews the 20 years of clinical experience with octreotide and the impact it has made in patients with acromegaly or GEP-NETs. RESULTS: Octreotide has proven to be an essential component in the management strategy of acromegaly and GEP-NETs over the past 20 years. The multiple beneficial effects of octreotide throughout the body, combined with its established safety profile (the most common adverse effects are injection-site pain and gastrointestinal events), have made it an appealing option for clinicians. The advent of the long-acting release (LAR) formulation of octreotide provided additional benefits to patients through monthly administration, while maintaining the efficacy and tolerability profile of the daily subcutaneous formulation. CONCLUSIONS: Octreotide is a potent synthetic somatostatin analogue that has become the mainstay of medical therapy for tumor control in neuroendocrine disorders such as acromegaly and GEP-NETs. The development of octreotide LAR offered a further advancement; less frequent dosing provided valuable benefits in quality of life to patients, with equivalent efficacy and tolerability. Moreover, recent results from the PROMID study have confirmed the antiproliferative effect of octreotide LAR in patients with well-differentiated metastatic GEP-NETs of the midgut. New therapeutic uses of octreotide are currently under investigation in a variety of clinical settings.

Medical therapy of adrenocortical tumors.

Medical therapy is but one of a multiarm, multispecialty approach that is needed in order to successfully treat adrenocortical tumors. The role of surgery, radiation therapy, radiofrequency ablation, and the need for a team approach for the care of the patient cannot be over-emphasized. In this article current and potential future medical therapies for adrenocortical tumors are reviewed.
