Natural history of nonfunctioning pituitary macroadenomas followed without intervention: A retrospective cohort study. Clin Endocrinol (Oxf) 2023; 98:559-566. [PMID: 36600448 DOI: 10.1111/cen.14877] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/02/2022] [Revised: 12/29/2022] [Accepted: 01/03/2023] [Indexed: 01/06/2023]
Abstract
OBJECTIVE The treatment strategy for nonfunctioning pituitary adenomas (NFPA) includes surgery, radiotherapy, medical treatment, or follow-up. Prior series of patients with NFPAs followed without intervention include small numbers of patients with macroadenomas. This study investigated the natural history of patients with macroadenomas followed without treatment. DESIGN AND PATIENTS Retrospective cohort study included patients>18 years, with a diagnosis of NFPA ≥ 10 mm who were naïve to surgery or medical treatment and followed more than 12 months after diagnosis. Patients with chiasmal threat were excluded. Follow-up terminated if the patient underwent surgery, received cabergoline or was lost to follow-up. MEASUREMENTS Data collected included evaluation of tumour characteristics and size by MRI, symptoms including visual disturbances, and hormonal levels. Tumour growth was defined as maximal diameter increase of ≥2 mm. RESULTS The cohort included 49 patients (30 males, mean age 68.0 ± 12.0 years). At diagnosis, the average tumour size was 17.8 ± 5.9 mm. Mean follow-up time was 4.9 ± 4.9 years. Increase in tumour size occurred in 16 patients (33%), with an average growth of 5.1 ± 4.4 mm. Reduction in tumour size occurred in 10 patients (20%), with a mean decrease of 3.5 ± 1.3 mm. Twenty-three patients remained with stable tumours. Overall, 33 patients (67%) were observed without any intervention; 3 patients were operated and 13 were treated with cabergoline. None of the parameters including age, gender, baseline tumour size, invasiveness, visual disturbances, or hypopituitarism at diagnosis, predicted tumour growth. CONCLUSION Observation of NFPAs without surgery or medical therapy is a reasonable approach in selected patients. In our study, no parameter predicted tumour growth.

Abstract
Pachydermoperiostosis is a rare genetic disease that is associated with HPGD (15-hydroxyprostaglandin dehydrogenase) and SLCO2A1 (solute carrier organic anion transporter family member 2A1) gene mutations. It is characterized by three major phenotypes, namely, pachydermia, periostosis, and digital clubbing. Clinically, misdiagnoses such as acromegaly and thyroid acropachy are commonly confused with pachydermoperiostosis. Integral medical history, physical examination, endocrinological tests, and multiple disciplinary cooperation are extremely significant in the accurate diagnosis of pachydermoperiostosis. The co-existence of pachydermoperiostosis and pituitary adenoma is rarely recorded and discussed. In this case, we present a young male patient with a complete form of pachydermoperiostosis and a nonfunctional pituitary microadenoma, which has rarely been reported.

Abstract
A 55-year-old woman admitted for hypertensive emergency and myocardial infarction reported weight gain, muscle weakness, easy bruising, and recent-onset diabetes in the past 3 to 12 months. Urinary and salivary cortisol and adrenocorticotropin hormone (ACTH) levels were elevated. Pituitary imaging detected a macroadenoma. ACTH and cortisol did not increase after corticotropin-releasing hormone administration. Imaging revealed a large pancreatic mass. Pathology indicated a well-differentiated World Health Organization (WHO) grade 2 distal pancreatic neuroendocrine neoplasm which stained for ACTH by immunohistochemistry. Postoperatively, Cushing manifestations resolved, ACTH and cortisol levels became low, and patient required hydrocortisone replacement for 7 months. During the 3.5 years of follow-up, the pituitary macroadenoma size remained stable and pituitary hormone axes other than ACTH remained normal. This extremely rare case of ectopic ACTH-secreting pancreatic neuroendocrine tumor coexisting with a nonfunctioning pituitary macroadenoma illustrates the importance of dynamic endocrine testing in Cushing syndrome.

Abstract
Simple Summary A pituitary incidentaloma is a pituitary tumor or mass that is incidentally discovered in imaging studies which have been performed for reasons other than the symptoms of pituitary lesions. The majority of pituitary incidentalomas are pituitary neuroendocrine tumors (PitNETs) and Rathke cleft cysts. PitNETs have received attention because of their distinction from pituitary adenoma in the new World Health Organization (WHO) classification. The natural history of PitNETs is partially known, and the management of pituitary incidentalomas has been determined based on this history; however, the pathology of PitNETs has significantly changed with the new WHO classification, and studies with a high level of evidence are required to consider treatment guidelines for pituitary incidentalomas. Abstract Pituitary incidentalomas are tumors or mass lesions of the pituitary gland. These are incidentally discovered during imaging studies for symptoms that are not causally related to pituitary diseases. The most common symptom that triggers an examination is headache, and the most common type of pituitary incidentalomas are pituitary neuroendocrine tumors (PitNETs) and Rathke cleft cysts. The existing treatment strategy is controversial; however, surgical resection is recommended in cases of clinically non-functioning PitNETs with optic chiasm compression. In contrast, cystic lesions, such as Rathke cleft cysts, should be followed if the patients are asymptomatic. In this case, MRI and pituitary function tests are recommended every six months to one year; if there is no change, the follow-up period should be extended. The natural history of PitNET is partially known, and the management of pituitary incidentalomas is determined by this history. However, the pathogenesis of PitNET has significantly changed with the new World Health Organization classification, and follow-up is important based on this new classification. Therefore, a high level of evidence-based research is needed to consider treatment guidelines for pituitary incidentalomas in the future.

Abstract
Purpose Reported rates of incidentally discovered pituitary sellar lesions vary widely, at least in part because of the inadvertent inclusion of patients with a history suspicious for a pituitary disorder. We prospectively evaluated the incidence of truly incidental sellar findings detected on imaging at a large academic medical center. Methods Deidentified data were extracted from the electronic medical record of adults who underwent diagnostic computed tomography (CT) or magnetic resonance imaging (MRI) over a 1-year period for any cause unrelated to known or suspected pituitary disorder both in inpatient and outpatient settings. Patients with International Classification of Diseases, Ninth Revision, (ICD-9) and Tenth Revision (ICD-10) codes indicative of a sellar lesion and those with symptoms suggestive of sellar/parasellar mass effects were excluded. Results Of 9572 scans performed during the 1-year study period, 3840 met the inclusion criteria to comprise the study cohort; 13 were manually excluded because of findings or symptoms of sellar masses not otherwise captured. The overwhelming majority of evaluable images (n = 3782) showed no sellar lesions. Truly incidental sellar findings were detected in 45 (1.2%), most commonly among inpatients (P < .001). Partially empty sella and empty sella were the most frequent findings, and were twice as likely to be detected on MRI vs CT. All other incidentally discovered lesions, including one microadenoma and one macroadenoma, were detected only by MRI. Conclusion Frequency of incidental sellar lesions in patients with no known or suspected history of pituitary disorder is low. Given the small likelihood of aggressive behavior in these lesions, the clinical significance of truly incidentally discovered sellar lesions should not be overestimated.

Abstract
Transsphenoidal surgery (TSS) represents the gold standard of pituitary adenoma resection, providing a safe and minimal invasive treatment for patients suffering from symptoms of mass effect. The aim of this study is to analyze the postoperative improvement of visual function after adenoma resection and to identify prognostic factors for the postoperative clinical recovery. We performed a retrospective analysis of all consecutive patients treated via a transsphenoidal approach for pituitary adenomas from April 2006 to December 2019 in a high-volume neurosurgical department. Our primary outcome was postoperative visual acuity and visual field impairment; the clinical findings were followed up to 3 months after surgery and correlated with clinical and radiographic findings. In total, 440 surgeries were performed in our department for tumors of the sella region in a time period of 13 years via transsphenoidal approach, and 191 patients included in the analysis. Mean age was 55 years, and 98% were macroadenomas. Mean preoperative visual acuity in patients with preoperative impairment (n = 133) improved significantly from 0.64/0.65 to 0.72/0.75 and 0.76/0.8 (right eye R/left eye L) postoperatively and at 3 months follow-up (p < 0.001). Visual acuity significantly depended on Knosp classification but not Hardy grading. The strongest predictor for visual function recovery was age. Transsphenoidal pituitary tumor resection remains a safe and effective treatment in patients with preoperative visual impairment. It significantly improves visual acuity and field defects after surgery, and recovery continues at the 3 months follow-up examination.

Abstract
Non-functioning pituitary adenomas (NFPAs) are benign pituitary tumours that constitute about one-third of all pituitary adenomas. They typically present with symptoms of mass effects resulting in hypopituitarism, visual symptoms, or headache. Most NFPAs are macroadenomas (>1 cm in diameter) at diagnosis that can occasionally grow quite large and invade the cavernous sinus causing acute nerve compression and some patients may develop acute haemorrhage due to pituitary apoplexy. The progression from benign to malignant pituitary tumours is not fully understood; however, genetic and epigenetic abnormalities may be involved. Non-functioning pituitary carcinoma is extremely rare accounting for only 0.1% to 0.5 % of all pituitary tumours and presents with cerebrospinal, meningeal, or distant metastasis along with the absence of features of hormonal hypersecretion. Pituitary surgery through trans-sphenoidal approach has been the treatment of choice for symptomatic NFPAs; however, total resection of large macroadenomas is not always possible. Recurrence of tumours is frequent and occurs in 51.5% during 10 years of follow-up and negatively affects the overall prognosis. Adjuvant radiotherapy can decrease and prevent tumour growth but at the cost of significant side effects. The presence of somatostatin receptor types 2 and 3 (SSTR3 and SSTR2) and D2-specific dopaminergic receptors (D2R) within NFPAs has opened a new perspective of medical treatment for such tumours. The effect of dopamine agonist from pooled results on patients with NFPAs has emerged as a very promising treatment modality as it has resulted in reduction of tumour size in 30% of patients and stabilization of the disease in about 58%. Despite the lack of long-term studies on the mortality, the available limited evidence indicates that patients with NFPA have higher standardized mortality ratios (SMR) than the general population, with women particularly having higher SMR than men. Older age at diagnosis and higher doses of glucocorticoid replacement therapy are the only known predictors for increased mortality.

Identification of key genes in invasive clinically non-functioning pituitary adenoma by integrating analysis of DNA methylation and mRNA expression profiles. J Transl Med 2019; 17:407.

Abstract
BACKGROUND Tumor surrounding the internal carotid artery or invading to the cavernous sinus is an important characteristic of invasive pituitary adenoma, and a pivotal factor of tumor residue and regrowth. Without specific changes in serum hormone related to the adenohypophyseal cell of origin, clinically non-functioning pituitary adenoma is more likely to be diagnosed at invasive stages compared with functioning pituitary adenoma. The underlying mechanism of tumor invasion remains unknown. In this study, we aimed to identify key genes in tumor invasion by integrating analyses of DNA methylation and gene expression profiles. METHOD Genome-wide DNA methylation and mRNA microarray analysis were performed for tumor samples from 68 patients at the Beijing Tiantan Hospital. Differentially expressed genes and methylated probes were identified based on an invasive vs non-invasive grouping. Differentially methylated probes in the promoter region of targeted genes were assessed. Pearson correlation analysis was used to identify genes with a strong association between DNA methylation status and expression levels. Pyrosequencing and RT-PCR were used to validate the methylation status and expression levels of candidate genes, respectively. RESULTS A total of 8842 differentially methylated probes, located on 4582 genes, and 661 differentially expressed genes were identified. Both promoter methylation and expression alterations were observed for 115 genes with 58 genes showing a negative correlation between DNA methylation status and expression level. Nineteen genes that exhibited notably negative correlations between DNA methylation and gene expression levels, are involved in various gene ontologies and pathways, or played an important role in different diseases, were regarded as candidate genes. We found an increased methylation with a decreased expression of PHYHD1, LTBR, C22orf42, PRR5, ANKDD1A, RAB13, CAMKV, KIFC3, WNT4 and STAT6, and a decreased methylation with an increased expression of MYBPHL. The methylation status and expression levels of these genes were validated by pyrosequencing and RT-PCR. CONCLUSIONS The DNA methylation and expression levels of PHYHD1, LTBR, MYBPHL, C22orf42, PRR5, ANKDD1A, RAB13, CAMKV, KIFC3, WNT4 and STAT6 are associated with tumor invasion, and these genes may become the potential genes for targeted therapy.

Abstract
Pregnancy is characterized by marked alterations in the hypothalamic-pituitary-adrenal axis and in the function of the adrenal gland. Some of those alterations have clinical characteristics that are similar to those of adrenal gland disorders. While adrenal disorders are rare among pregnant women, they harbor the potential for significant morbidity if they remain unrecognized and untreated. As the majority of patients with adrenal disorders present with clinical features that are typical of normal pregnancy - diagnosis during pregnancy is not uncommonly delayed. A high index of suspicion must be practiced for these disorders as they might carry severe obstetrical negative outcomes. In this review we will survey the normal function of adrenal glands in pregnancy and the role of adrenal hormones in pregnancy. We will outline the adrenal disorders that commonly present during pregnancy and review the literature on treatment modalities.

Abstract
BACKGROUND The availability of magnetic resonance imaging (MRI) has led to an increase in the detection of pituitary incidentaloma (PI). However, there are no robust data on surgical treatment of PI on which to base therapeutic recommendations. This study was performed to investigate the significance of surgery for asymptomatic nonfunctioning pituitary adenoma (NFPA) among PIs. METHODS A total of 180 patients that underwent tumor resection of pituitary adenoma via the transsphenoidal approach between 2005 and 2017 were reviewed. Thirty-three consecutive patients with subjectively asymptomatic NFPA were included in this study. Our surgical indications for asymptomatic NFPAs were categorized as follows: macroadenoma with optic chiasma compression (group A, n = 14), solid tumor ≥2 cm in size (group B, n = 7), and tumor growth on follow-up MRI (group C, n = 12). The clinical outcomes were analyzed accordingly. RESULTS Seven patients (50%) in group A showed subjective improvement of visual function after tumor resection even though they had no complaints preoperatively. On the other hand, no changes occurred in any cases in group B or group C. Although there were no critical complications in this series, the incidence of nonnegligible nasal complications was relatively high (24.2%) and may decrease the patient's quality of life. CONCLUSIONS Surgery should be recommended for asymptomatic NFPA with optic chiasma compression to improve visual outcome. On the other hand, immediate intervention for other asymptomatic NFPA to reduce the likelihood of the appearance of tumor-related symptoms remains questionable considering its invasiveness to the nose.

Abstract
Cushing's syndrome (CS) is a clinical syndrome characterized by hypercortisolemia. Cyclic Cushing's syndrome (CCS), which exhibits a periodic or irregular increasing pattern in cortisol, is a rare type of Cushing's syndrome. A 37-year-old man came to our hospital because of repeated dizzy spells, weakness and hypercortisolemia lasting two weeks. Endocrinological examinations indicated CCS with periodic and intermittent increases in cortisol. Enhanced computed tomography (CT) revealed space occupying lesions on the upper lobe of left lung, and biopsy eventually proved that these were pulmonary carcinoid tumors with ectopic ACTH secretion, which was subsequently manifested a Cushing's syndrome. PET-CT, ultrasound and biopsy of the thyroid gland indicated bilateral thyroid papillary carcinoma. CT scan showed bilateral nodular hyperplasia of the adrenal gland. Enhanced magnetic resonance imaging (MRI) confirmed that the high signal disappeared on the posterior lobe of the pituitary gland and that the pituitary stalk shifted left, which was suspected to be non-functional pituitary microadenoma. The patient underwent surgery involving resection of the left upper pulmonary lobe and the mediastinal lymph node around the hilus pulmonis, which resulted in complete remission of CCS. The patient then chose elective surgery for the thyroid papillary carcinoma. An analysis of the patient's genomic DNA identified a novel mutation in PDE11A: c.2032 (exon 12) G > A, which is associated with primary pigmented nodular adrenocortical disease (PPNAD). This is a novel mutation which has been no previous public clinical report on this mutation as it relates to this disease.

Abstract
An appropriate diagnostic evaluation is essential for the most appropriate treatment to be performed. Currently, macroprolactinemia is the third most frequent cause of nonphysiological hyperprolactinemia after drugs and prolactinomas. Up to 40% of macroprolactinemic patients may present with hypogonadism symptoms, infertility, and/or galactorrhea. Thus, the screening for macroprolactin is indicated not only for asymptomatic subjects but also for those without an obvious cause for their prolactin (PRL) elevation. Before submitting patients to macroprolactin screening and pituitary magnetic resonance imaging, one should rule out pregnancy, drug-induced hyperprolactinemia, primary hypothyroidism, and renal failure. The magnitude of PRL elevation can be useful in determining the etiology of hyperprolactinemia. PRL values >250 ng/mL are highly suggestive of prolactinomas and virtually exclude nonfunctioning pituitary adenomas (NFPAs) and other sellar masses as the etiology of hyperprolactinemia. However, they can also be found in subjects with macroprolactinemia, drug-induced hyper-prolactinemia or chronic renal failure. By contrast, most patients with NFPAs, drug-induced hyperprolactinemia, macroprolactinemia, or systemic diseases present with PRL levels <100 ng/mL. However, exceptions to these rules are not rare. Indeed, up to 25% of patients harboring a microprolactinoma or a cystic macroprolactinoma may also have PRL <100 ng/mL. Falsely low PRL levels may result from the so-called "hook effect," which should be considered in all cases of large (≥3 cm) pituitary adenomas associated with normal or mildly elevated PRL levels (≤250 ng/mL). The hook effect may be unmasked by repeating PRL measurement after a 1:100 serum sample dilution.

Abstract
Clinically nonfunctioning pituitary adenomas (NFAs) range from those causing significant hypothalamic/pituitary dysfunction and visual field compromise due to their large size to those being completely asymptomatic. In the absence of hypersecretion, hypopituitarism or visual field defects, patients with NFAs may be followed by periodic surveillance using MRI to detect tumor enlargement. In some cases, endocrine tests are also needed during observation to discover new pituitary dysfunction. Enlargement of NFAs without treatment occurs in about 10% of microadenomas and 23% of macroadenomas. Growth of a pituitary incidentaloma, the development of visual field defects or the development of hypopituitarism are potential indications for surgery during follow up.

Three-Dimensional Endoscopic Endonasal Approach and Outcomes in Sellar Lesions: A Single-Center Experience of 104 Cases. World Neurosurg 2016; 89:121-5. [PMID: 26836697 DOI: 10.1016/j.wneu.2016.01.049] [Citation(s) in RCA: 26] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/24/2015] [Revised: 01/17/2016] [Accepted: 01/19/2016] [Indexed: 10/22/2022]
Abstract
BACKGROUND Pituitary tumors account for approximately 15% of primary intracranial neoplasms and often are diagnosed incidentally. Common sellar lesions are pituitary adenomas, craniopharyngiomas, and Rathke cleft cysts. Currently endoscopic transsphenoidal approaches are largely used, and many centers also use 3-dimensional (3D) technology, although additional results of long-term follow-up are still being accumulated. METHODS We present a retrospective analysis of 104 patients with sellar lesions (57 male and 47 female, mean age 52 years) who underwent 3D endoscopic transsphenoidal surgery in our center from December 2011 to March 2015 and were followed up for a mean time of 18 months. RESULTS A total of 16 patients were diagnosed with growth hormone-secreting adenomas, 9 with adrenocorticotropic hormone-secreting, 5 with prolactin-secreting, and 2 with thyroid-stimulating hormone-secreting tumors and 58 with nonsecreting pituitary adenomas. Five patients had Rathke cleft cysts, 5 craniopharyngiomas, 2 fibrous solitary tumors, 1 a metastasis, and 1 a chordoma. At baseline, 47 patients (45.2%) had hormonal changes and 52 (50%) had visual field changes. Complete resection was achieved in 73 patients (70.1%). Follow-up evaluation detected hormonal remission in 7 patients with Cushing disease (77.7%) and in 11 patients with acromegaly (68.7%). Complications were cerebrospinal fluid leak in 5 cases (4.8%) and transient diabetes insipidus in 6 cases (5.7%). A total of 55 patients (52.9%) were discharged less than 72 hours after surgery. CONCLUSIONS The use of an endoscopic endonasal approach with 3D technology provides several advantages relating to patient length of stay, rate of complications, postoperative recovery, and novice surgeons' training. Advantages of 3D endoscopy and long-term follow-up still need further elucidation.

Abstract
CONTEXT The natural history and the optimum management of patients with nonfunctioning pituitary adenomas (NFPAs) are unclear. OBJECTIVE Our objective was to characterize the natural history of patients with NFPAs managed conservatively. DESIGN AND PATIENTS We conducted a retrospective analysis of patients presenting to a tertiary referral centre between 1986 and 2009. Patients with pituitary adenomas and no clinical or biochemical evidence of hormonal hypersecretion were included. Those presenting with apoplexy or a radiological follow-up period of less than 1 year were excluded. The pituitary imaging for all patients was re-examined by two neuroradiologists in consensus. OUTCOME MEASURES The outcome measures were change in tumour size and pituitary hormone function. RESULTS Sixty-six patients were managed conservatively for a mean follow-up period of 4·3 years (range: 1-14·7). Forty-seven (71%) had a macroadenoma, and nineteen (29%) had a microadenoma. Tumour size decreased or remained stable in 40% of macroadenomas and 47% of microadenomas. The median annual growth rate of enlarging macroadenomas and microadenomas was 1·0 mm/year and 0·4 mm/year, respectively. The median annual growth rate of macroadenomas was significantly higher than that of microadenomas (P < 0·01). Sixty-eight percentage of patients with a macroadenoma had pituitary hormone deficiency in one or more axes, compared to 42% of those with a microadenoma. CONCLUSION Patients with NFPAs without optic chiasm compression can be managed conservatively. All patients need pituitary function assessment, irrespective of tumour size. These findings provide clinically relevant data for the management of patients with NFPAs.

Abstract
The definition of the etiology of hyperprolactinemia often represents a great challenge and an accurate diagnosis is paramount before treatment. Although prolactin levels > 200-250 ng/mL are highly suggestive of prolactinomas, they can occasionally be found in other conditions. Moreover, as much as 25% of patients with microprolactinomas may present prolactin levels < 100 ng/mL, which are found in most patients with pseudoprolactinomas, drug-induced hyperprolactinemia, or systemic diseases. On the other hand, some conditions may lead to falsely low PRL levels, particularly the so-called hook effect, that is an assay artifact caused by an extremely high level of PRL, and can be confirmed by repeating assay after a 1:100 serum sample dilution. The hook effect must be considered in all patients with large pituitary adenomas and PRL levels within the normal range or only modestly elevated (e.g., < 200 ng/mL). An overlooked hook effect may lead to incorrect diagnosis and unnecessary surgical intervention in patients with prolactinomas. Another important challenge is macroprolactinemia, a common finding that needs to be identified, as it usually requires no treatment. Although most macroprolactinemic patients are asymptomatic, many of them may present galactorrhea or menstrual disorders, as well as neuroradiological abnormalities, due to the concomitance of other diseases. Finally, physicians should be aware that pituitary incidentalomas are found in at least 10% of adult population.

Abstract
Pituitary tumors are common in the general population. Since neuroimaging techniques have improved, pituitary tumors are more often diagnosed incidentally. About 16.7% of the general population show changes in the pituitary gland. Predominantly, pituitary tumors are benign pituitary adenomas. Pituitary carcinomas or aggressive pituitary tumors are extremely rare. They might develop from benign adenomas. New genetic and epigenetic abnormalities help us to understand pituitary tumorigenesis and might lead to therapeutical targeting drugs in the future. Macroadenomas (>1 cm) can lead to visual field disturbances, compression of cranial nerves, hypopituitarism, and infiltration of the cavernous sinuses. The functional status of the pituitary tumor is important. About half to one third of all pituitary tumors are non-functioning pituitary adenomas. The other pituitary tumors show a specific pattern of hormone secretion. About 25% to 41% of all pituitary tumors are prolactinomas, acromegaly with production of growth hormone represents 10% to 15% of adenomas, Cushing's disease with production of adrenocorticotropic hormone accounts for 10%, and other hormonal characteristics are less common. Transsphenoidal resection and total adenomectomy are desirable. Radiosurgery has enriched the surgical treatment options. Surgical treatment is the intervention of choice except for prolactinomas, where pharmaceutical treatment is recommended. Pharmaceutical treatment consists of dopamine agonists such as cabergoline and somatostatin analogues that include octreotide and pasireotide; retinoic acid is of theoretical interest while peroxisome proliferator-activated receptor-gamma-ligands are not clinically useful. In acromegaly, pegvisomant is a further treatment option. Temozolomide should be considered in aggressive pituitary tumors. In general, pharmaceutical options developed recently have extended the repertoire of treatment possibilities of pituitary tumors.
