RESUMO

Pituitary deficiency, or hypopituitarism, is a rare chronic disease. It is defined by insufficient synthesis of one or more pituitary hormones (growth hormone, TSH, ACTH, LH-FSH, prolactin), whether or not associated with arginine vasopressin deficiency (formerly known as diabetes insipidus). In adult patients, it is usually acquired (notably during childhood), but can also be congenital, due to abnormal pituitary development. The present study focuses on congenital pituitary deficiency in adults, from diagnosis to follow-up, including special situations such as pregnancy or the elderly. The clinical presentation is highly variable, ranging from isolated deficit to multiple deficits, which may be part of a syndromic form or not. Diagnosis is based on a combination of clinical, biological (assessment of all hormonal axes), radiological (brain and hypothalamic-pituitary MRI) and genetic factors. Treatment consists in hormonal replacement therapy, adapted according to the period of life and the deficits, which may be progressive. Comorbidities, risk of complications and acute decompensation, and the impact on fertility and quality of life all require adaptative multidisciplinary care and long-term monitoring.

RESUMO

The SFE-AFCE-SFMN 2022 consensus deals with the management of thyroid nodules, a symptom that is a frequent reason for consultation in endocrinology. Thyroid nodules are very common and mostly benign. Thyroid ultrasound and thyroid fine-needle aspiration biopsy (FNAB) are the reference tests for the analysis of these nodules. The aim of this article is to describe for the cytopathologist the key points of the SFE-AFCE-SFMN 2022 consensus involving thyroid cytology: the indications for thyroid FNAB, the technique and analysis, and the management (treatment, follow-up) following this cytological screening examination, a key element in the management of the thyroid nodule.

RESUMO

CONTEXT: Diagnosis announcement of a chronic disease is a crucial moment for patients as well as for their families and an important step in the management of severe conditions such as rare endocrine diseases. Little is known of how diagnosis is communicated to patients and families. The FIRENDO network was created by the third French Plan for Rare Diseases, to promote autonomy, care and research on rare endocrine diseases. OBJECTIVES: The aim of this study was to characterize, for the first time, the experience and needs of patients and/or their parents around the announcement of diagnosis to ensure optimal quality of care. METHODS: A quantitative self-administered survey on diagnosis announcement procedures in rare endocrine diseases was launched in April 2017 by the ad hoc FIRENDO thematic working group in collaboration with its 11 partnering patient associations and support groups. The questionnaire was designed and revised by patient support group representatives, adult and pediatric endocrinologists, psychologists and biologists, all expert in rare endocrine diseases. It was made available on the FIRENDO network website and distributed mainly by email with electronic links on their respective websites to members of all affiliated patient support groups. RESULTS: Questionnaires were filled out by 391 patients and 223 parents (median age of patients: 39 years). The following conditions were associated with at least 30 answers: Addison's disease, classical forms of congenital adrenal hyperplasia (CAH), Russell-Silver syndrome, Cushing's syndrome, acromegaly and craniopharyngioma. Overall, some announcement modalities were judged favorably by patients: physician's empathy, availability and use of clear terms, and presence of family at the time of announcement. However, a lack of psychological care and information documents was reported, as well as some inadequate procedures such as postal mail announcements. CONCLUSION: This work suggests that better knowledge of the patient's experience is useful for improving the diagnosis announcement of rare endocrine disorders. The main recommendations derived from the survey were the need for several announcement visits, information on patient support groups and reference centers, imperatively avoiding impersonal announcement, and the usefulness of a written accompanying document.

RESUMO

Acromegaly is a rare disease with prevalence of approximately 60 cases per million, slight female predominance and peak onset in adults in the fourth decade. Clinical diagnosis is often delayed by several years due to the slowly progressive onset of symptoms. There are multiple clinical criteria that define acromegaly: dysmorphic syndrome of insidious onset, symptoms related to the pituitary tumor (headaches, visual disorders), general signs (sweating, carpal tunnel syndrome, joint pain, etc.), complications of the disease (musculoskeletal, cardiovascular, pneumological, dental, metabolic comorbidities, thyroid nodules, colonic polyps, etc.) or sometimes clinical signs of associated prolactin hypersecretion (erectile dysfunction in men or cycle disorder in women) or concomitant mass-induced hypopituitarism (fatigue and other symptoms related to pituitary hormone deficiencies). Biological confirmation is based initially on elevated IGF-I and lack of GH suppression on oral glucose tolerance test or an elevated mean GH on repeated measurements. In confirmed cases, imaging by pituitary MRI identifies the causal tumor, to best determine management. In a minority of cases, acromegaly can be linked to a genetic predisposition, especially when it occurs at a young age or in a familial context. The first-line treatment is most often surgical removal of the somatotroph pituitary tumor, either immediately or after transient medical treatment. Medical treatments are most often proposed in patients not controlled by surgical removal. Conformal or stereotactic radiotherapy may be discussed on a case-by-case basis, especially in case of drug inefficacy or poor tolerance. Acromegaly should be managed by a multidisciplinary team, preferably within an expert center such as a reference or skill center for rare pituitary diseases.

RESUMO

Over the past decade, the development of ICI (immune checkpoint inhibitors) has constituted a revolution in the treatment of many cancers, but with a specific toxicity profile including endocrine IRAEs (immune-related adverse events). As the indications for these molecules are constantly increasing due to their efficacy, it is important that endocrinologists and oncologists know how to detect, manage and monitor this type of toxicity. Many guidelines and recommendations have been proposed in the last few years for the management of endocrinopathies. French guidelines on immunotherapy-related endocrine IRAEs were published in 2018, with a specific algorithm for hypophysitis and primary adrenal insufficiency (PAI), based on clinical suspicion followed by biochemical and imaging evaluation, and are still relevant today. Here we present the general pathophysiological mechanisms of these toxicities, and discuss the incidence, diagnosis, treatment, progression, management and monitoring of pituitary and adrenal disorders in patients treated by immunotherapy, with emphasis on hypophysitis, which is much more frequent than PAI with this type of molecule. We also highlight several key points, such as the need for emergency treatment by hydrocortisone with the possibility of continuing immunotherapy in these endocrinopathies, and the long-term persistence of corticotropin or adrenal deficiency in most cases, requiring specific "hydrocortisone education". These points should be kept in mind by oncologists and endocrinologists who treat and monitor patients treated by immunotherapy.

RESUMO

Congenital hypopituitarism is a genetically heterogeneous condition that is part of a spectrum disorder that can include holoprosencephaly. Heterozygous mutations in SIX3 cause variable holoprosencephaly in humans and mice. We identified two children with neonatal hypopituitarism and thin pituitary stalk who were doubly heterozygous for rare, likely deleterious variants in the transcription factors SIX3 and POU1F1. We used genetically engineered mice to understand the disease pathophysiology. Pou1f1 loss-of-function heterozygotes are unaffected; Six3 heterozygotes have pituitary gland dysmorphology and incompletely ossified palate; and the Six3+/-; Pou1f1+/dw double heterozygote mice have a pronounced phenotype, including pituitary growth through the palate. The interaction of Pou1f1 and Six3 in mice supports the possibility of digenic pituitary disease in children. Disruption of Six3 expression in the oral ectoderm completely ablated anterior pituitary development, and deletion of Six3 in the neural ectoderm blocked the development of the pituitary stalk and both anterior and posterior pituitary lobes. Six3 is required in both oral and neural ectodermal tissues for the activation of signaling pathways and transcription factors necessary for pituitary cell fate. These studies clarify the mechanism of SIX3 action in pituitary development and provide support for a digenic basis for hypopituitarism.

RESUMO

Introduction: A gonadectomy is currently recommended in patients with Turner syndrome (TS) and a 45,X/46,XY karyotype, due to a potential risk of gonadoblastoma (GB). However, the quality of evidence behind this recommendation is low. Objective: This study aimed to evaluate the prevalence of GB, its characteristics, as well as its risk factors, according to the type of Y chromosomal material in the karyotype. Methods: Our study within French rare disease centers included patients with TS and a 45,X/46,XY karyotype, without ambiguity of external genitalia. Clinical characteristics of the patients, their age at gonadectomy, and gonadal histology were recorded. The regions of the Y chromosome, the presence of TSPY regions, and the percentage of 45,X/46,XY mosaicism were evaluated. Results: A total of 70 patients were recruited, with a median age of 29.5 years (21.0-36.0) at the end of follow-up. Fifty-eight patients had a gonadectomy, at a mean age of 15 ± 8 years. GB was present in nine cases. Two were malignant, which were discovered at the age of 14 and 32 years, without metastases. Neither the percentage of XY cells within the 45,X/46,XY mosaicism nor the number of TSPY copies was statistically different in patients with or without GB (P = 0.37). However, the entire Y chromosome was frequent in patients with GB (6/9). Conclusions: In our study, including a large number of patients with 45,X/46,XY TS, the prevalence of gonadoblastoma is 12.8%. An entire Y chromosome appears as the main risk factor of GB and should favor early gonadectomy. Significant statement: About 10% of patients with TS have a karyotype containing Y chromosomal material: 45,X/46,XY. Its presence is related to the risk of GB. Therefore, a prophylactic gonadectomy is currently recommended in such patients. However, the quality of evidence is low. Our objective was to evaluate the prevalence of GB according to the type of Y-chromosomal material. We found a prevalence of GB of 12.8% in a cohort of 70 TS patients. No sign of hyperandrogenism was observed. The entire Y chromosome was the most frequent type of Y-material in patients with GB. As the prognosis of these tumors was good, a delay of surgery might be discussed.

RESUMO

Transsphenoidal surgery is the first-line treatment for acromegaly. However, several factors can modify surgical remission rates, such as the initial hormone levels, the size and invasiveness of the tumor, and the degree of experience of the surgeon. Physicians treating patients with acromegaly should thus consider how to improve surgical remission rates. As stated in recent guidelines, the major point is to consider that any patient with acromegaly should be referred to an expert neurosurgeon to maximize the chances of surgical sure. The benefits of presurgical medical treatment, mainly using somatostatin receptor ligands (SRLs), given 3 to 6 months before surgery, remain controversial. By normalizing growth hormone and insulin-like growth factor 1 levels, SRLs may improve the overall condition of the patient, thus decreasing anesthetic and surgical complications. By decreasing the tumor size and modifying the consistency of the tumor, SRLs might also make surgical excision easier. This is however theoretical as published data are contradictory on both points, and only limited data support the use of a systematical presurgical medical treatment. The aim of this review is to analyze the potential benefits and pitfalls of using presurgical medical treatment in acromegaly in view of the contradictory literature data. We also attempt to determine the profile of patients who might most benefit from this presurgical medical treatment approach as an individualized therapeutic management of acromegaly.

RESUMO

Turner syndrome (TS; ORPHA 881) is a rare condition in which all or part of one X chromosome is absent from some or all cells. It affects approximately one in every 1/2500 liveborn girls. The most frequently observed karyotypes are 45,X (40-50%) and the 45,X/46,XX mosaic karyotype (15-25%). Karyotypes with an X isochromosome (45,X/46,isoXq or 45,X/46,isoXp), a Y chromosome, X ring chromosome or deletions of the X chromosome are less frequent. The objective of the French National Diagnosis and Care Protocol (PNDS; Protocole National de Diagnostic et de Soins) is to provide health professionals with information about the optimal management and care for patients, based on a critical literature review and multidisciplinary expert consensus. The PNDS, written by members of the French National Reference Center for Rare Growth and Developmental Endocrine disorders, is available from the French Health Authority website. Turner Syndrome is associated with several phenotypic conditions and a higher risk of comorbidity. The most frequently reported features are growth retardation with short adult stature and gonadal dysgenesis. TS may be associated with various congenital (heart and kidney) or acquired diseases (autoimmune thyroid disease, celiac disease, hearing loss, overweight/obesity, glucose intolerance/type 2 diabetes, dyslipidemia, cardiovascular complications and liver dysfunction). Most of the clinical traits of TS are due to the haploinsufficiency of various genes on the X chromosome, particularly those in the pseudoautosomal regions (PAR 1 and PAR 2), which normally escape the physiological process of X inactivation, although other regions may also be implicated. The management of patients with TS requires collaboration between several healthcare providers. The attending physician, in collaboration with the national care network, will ensure that the patient receives optimal care through regular follow-up and screening. The various elements of this PNDS are designed to provide such support.

RESUMO

INTRODUCTION: Persistent growth hormone hypersecretion can be observed in roughly 50% of patients operated for somatotroph adenomas, requiring additional treatments. Despite its proven antisecretory efficacy, the use of Gamma Knife radiosurgery (GK) is limited probably due to the lack of data on long-term side effects, including potential cognitive consequences. METHODS: The LATe Effects of Radiosurgery in Acromegaly study was a cross-sectional exposed/unexposed non-randomized study. The primary objective was to determine the long-term neurocognitive effects of GK focusing on memory, executive functions, and calculation ability. Exposed patients had been treated by GK for acromegaly at least 5 years before inclusion. Unexposed patients (paired for age) had to be cured or controlled at last follow-up without any radiation technique. Patients of both groups were cured or controlled at the last follow-up. RESULTS: Sixty-four patients were evaluated (27 exposed and 37 unexposed). Mean follow-up after GK was 13 ± 6 years (including 24 patients followed for at least 10 years). While up to 23.8% of the patients of the whole cohort presented at least one abnormal cognitive test, we did not observe any significant difference in neurocognitive function between both groups. During the follow-up, 11 patients presented at least one new pituitary deficiency (P = 0.009 for thyroid-stimulating hormone deficiency with a higher rate in exposed patients), two presented a stroke (1 in each group), and one presented a meningioma (12 years after GK). CONCLUSIONS: While GK exposes patients to a well-known risk of pituitary deficiency, it does not seem to induce long-term cognitive consequences in patients treated for acromegaly.

RESUMO

OBJECTIVE: A relative can be an asset in dealing with chronic illnesses, such as acromegaly, where quality of life (QoL) is altered even after remission. However, it has been shown that quality of life of caregivers can also be impacted. Our main objective was to compare the perception of acromegaly in remission in the patient-relative dyad. METHODS: In this observational study, 27 patients in remission and relatives were first asked to complete QoL, anxiety/depression and coping strategy questionnaires. Then, the patient's body image and self-esteem were evaluated from both the patient's and the relative's point of view using the same questionnaires with modified instructions. RESULTS: Relatives had overall an accurate estimation of patient body image using the Figure Rating Scale by Stunkard. However, there were wide variations between the patient's and the relative's responses regarding self-esteem and body perception. The QoL of relatives was not altered and was significantly higher in the social domain than for the patient. CONCLUSIONS: Our results show that relatives require education concerning all the steps involved in the management of acromegaly, as they likely do not fully understand the sequelae of acromegaly.

RESUMO

Premature ovarian insufficiency (POI) is a rare pathology affecting 1-2% of under-40 year-old women, 1 in 1000 under-30 year-olds and 1 in 10,000 under-20 year-olds. There are multiple etiologies, which can be classified as primary (chromosomal, genetic, auto-immune) and secondary or iatrogenic (surgical, or secondary to chemotherapy and/or radiotherapy). Despite important progress in genetics, more than 60% of cases of primary POI still have no identifiable etiology; these cases are known as idiopathic POI. POI is defined by the association of 1 clinical and 1 biological criterion: primary or secondary amenorrhea or spaniomenorrhea of>4 months with onset before 40 year of age, and elevated follicle-stimulating hormone (FSH)>25IU/L on 2 assays at>4 weeks' interval. Estradiol level is low, and anti-Müllerian hormone (AMH) levels have usually collapsed. Initial etiological work-up comprises auto-immune assessment, karyotype, FMR1 premutation screening and gene-panel study. If all of these are normal, the patient and parents may be offered genome-wide analysis under the "France Génomique" project. The term ovarian insufficiency suggests that the dysfunction is not necessarily definitive. In some cases, ovarian function may fluctuate, and spontaneous pregnancy is possible in around 6% of cases. In confirmed POI, hormone replacement therapy is to be recommended at least up to the physiological menopause age of 51 years. Management in a rare diseases center may be proposed.

RESUMO

BACKGROUND: Elevated plasma concentrations of hepatic- and intestinally-derived triglyceride-rich lipoproteins (TRL) are implicated in the pathogenesis of atherosclerotic cardiovascular disease and all-cause mortality. Excess of TRL is the driving cause of atherogenic dyslipidemia commonly occurring in insulin-resistant individuals such as patients with obesity, type 2 diabetes and metabolic syndrome. Interestingly, growth hormone (GH)-deficient individuals display similar atherogenic dyslipidemia, suggesting an important role of GH and GH deficiency in the regulation of TRL metabolism. OBJECTIVE: We aimed to examine the direct and/or indirect role of GH on TRL metabolism. METHODS: We investigated the effect on fasting and postprandial hepatic-TRL and intestinal-TRL metabolism of short-term (one month) withdrawal of GH in 10 GH-deficient adults. RESULTS: After GH withdrawal, we found a reduction in fasting plasma TRL concentration (significant decrease in TRL-TG, TRL-cholesterol, TRL-apoB-100, TRL-apoC-III and TRL-apoC-II) but not in postprandial TRL response. This reduction was due to fewer fasting TRL particles without a change in TG per particle and was not accompanied by a change in postprandial TRL-apoB-48 response. Individual reductions in TRL correlated strongly with increases in insulin sensitivity and decreases in TRL-apoC-III. CONCLUSION: In this relatively short term 'loss of function' human experimental model, we have shown an unanticipated reduction of hepatic-TRL particles despite increase in total body fat mass and reduction in lean mass. These findings contrast with the atherogenic dyslipidemia previously described in chronic GH deficient states, providing a new perspective for the role of GH in lipoprotein metabolism.

RESUMO

Pituitary hormone deficiency occurs in ∼1:4,000 live births. Approximately 3% of the cases are due to mutations in the alpha isoform of POU1F1, a pituitary-specific transcriptional activator. We found four separate heterozygous missense variants in unrelated individuals with hypopituitarism that were predicted to affect a minor isoform, POU1F1 beta, which can act as a transcriptional repressor. These variants retain repressor activity, but they shift splicing to favor the expression of the beta isoform, resulting in dominant-negative loss of function. Using a high-throughput splicing reporter assay, we tested 1,070 single-nucleotide variants in POU1F1. We identified 96 splice-disruptive variants, including 14 synonymous variants. In separate cohorts, we found two additional synonymous variants nominated by this screen that co-segregate with hypopituitarism. This study underlines the importance of evaluating the impact of variants on splicing and provides a catalog for interpretation of variants of unknown significance in POU1F1.

RESUMO

BACKGROUND: Previous quantitative studies have shown a reduced quality of life in patients treated for craniopharyngioma (CP). However, few have assessed their sexual quality of life and other issues related to patient intimacy have not yet been addressed. Standardized questionnaires limit the approach to sexuality and the exploration of patient experiences. A qualitative study, which allows in-depth analysis, may represent an interesting approach to explore intimacy in women with a history of CP. OBJECTIVE: To assess the impact of a CP history on femininity and relationships in women. DESIGN AND PATIENTS: A qualitative study with semi-structured interviews was conducted with 15 adult women treated for CP during childhood, adolescence or at childbearing age up to 40 years of age. Interviews were audio recorded, anonymized and transcribed literally. Data analysis was carried out with an inductive approach according to the grounded theory method. RESULTS: Three main themes were identified: (a) apparent changes leading to altered self-perception that may impact on femininity and generate lower self-esteem; (b) managing the hidden disabilities of the disease inducing a need for permanent control; and (c) building parenthood and couple relationships: coping with sexual dysfunction and infertility. CONCLUSIONS: Our study highlighted alterations in self-perception and femininity due to body change and disability resulting from CP treatment, impacting both couple and social relationships. Interviewing women who underwent CP surgery at different ages highlighted specific needs and different expectations of medical professionals which emphasize the importance of offering both global and personalized care.

RESUMO

First-line treatment of prolactinoma is usually medical, based on dopamine agonists receptors, mainly cabergoline. The classical side-effects of cabergoline (low blood pressure and nausea) have been well known since it was first introduced. Other side-effects, however, are more controversial or simply less frequent, but need to be considered during monitoring. This review will focus on these side-effects: cardiac valvular fibrosis, pleural, pericardial and retroperitoneal fibrosis, addictive/compulsive behaviors, and risks secondary to significantly decreased tumor volume. We will also describe how such side-effects should be monitored and managed. In our opinion, the low prevalence of these side-effects should not cast doubt on the role of cabergoline in the therapeutic algorithm of prolactinoma.

BACKGROUND: The '3PAs' syndrome, associating pituitary adenoma (PA) and pheochromocytoma/paraganglioma (PPGL), is sometimes associated with mutations in PPGL-predisposing genes, such as SDHx or MAX. In '3PAs' syndrome, PAs can occur before PPGL, suggesting a new gateway into SDHx/MAX-related diseases. OBJECTIVE: To determine the SDHx/MAX mutation prevalence in patients with isolated PAs and characterize PAs of patients with SDHx/MAX mutations. DESIGN: Genes involved in PAs (AIP/MEN1/CDKN1B) or PPGLs (SDHx/MAX) were sequenced in patients with isolated PAs. We then conducted a review of cases of PA in the setting of '3PAs' syndrome. RESULTS: A total of 263 patients were recruited. Seven (likely) pathogenic variants were found in AIP, two in MEN1, two in SDHA, and one in SDHC. The prevalence of SDHx mutations reached 1.1% (3/263). Of 31 reported patients with PAs harboring SDHx/MAX mutations (28 published cases and 3 cases reported here), 6/31 (19%) developed PA before PPGL and 8/31 (26%) had isolated PA. The age of onset was later than in patients with AIP/MEN1 mutations. PAs were mainly macroprolactinomas and showed intracytoplasmic vacuoles seen on histopathology. CONCLUSIONS: We discovered SDHx mutations in patients bearing PA who had no familial or personal history of PPGL. However, the question of incidental association remains unresolved and data to determine the benefit of SDHx/MAX screening in these patients are lacking. We recommend that patients with isolated PA should be carefully examined for a family history of PPGLs. A family history of PPGL, as well as the presence of intracytoplasmic vacuoles in PA, requires SDHx/MAX genetic testing of patients.

RESUMO

CONTEXT: In patients treated with antipsychotics, the rare occurrence of a macroprolactinoma represents a therapeutic challenge. OBJECTIVE: Our aim was to evaluate the efficacy and psychiatric safety of dopamine agonists (DAs) prescribed for large macroprolactinomas in patients with psychosis treated with antipsychotics. DESIGN: This was a multicenter (France and Belgium) retrospective study. PATIENTS: Eighteen patients treated with antipsychotics were included. RESULTS: Under DA, median PRL levels decreased from 1247 (117-81 132) to 42 (4-573) ng/mL (P = 0.008), from 3850 (449-38 000) to 141 (60-6000) ng/mL (P = 0.037) and from 1664 (94-9400) to 1215 (48-5640) ng/mL (P = 0.56) when given alone (n = 8), before surgery (n = 7), or after surgery (n = 6), respectively. The prolactinoma median largest diameter decreased by 28% (0-57) in patients under DAs alone (P = 0.02) but did not change when given after surgery. Optic chiasm decompression was achieved in 82% of patients. Five patients (28%) were admitted for psychotic relapse while receiving DAs (but three of them had stopped antipsychotic treatment at that time). A more severe underlying psychosis, rather than the DA treatment itself, may explain such psychiatric admissions. CONCLUSIONS: Even if the DA efficacy on PRL levels and tumor volume in patients with macroprolactinoma under antipsychotic drugs is less impressive than that typically observed, it may be considered satisfactory for half of our patients, particularly in cases of optic chiasm compression. Psychotic exacerbation was unusual in these patients, occurring mostly in those with the most severe psychotic forms. DAs may therefore be used as antitumor treatment for macroprolactinoma in patients with visual involvement, severe headaches or invasion into the skull base who receive antipsychotics.

RESUMO

OBJECTIVE: The aim of this study was to describe endocrinological outcome in patients operated on for acromegaly. METHODS: A retrospective study included 167 patients. Patients were assessed in the early postoperative period (EPP), at 3 months (M3), at 1 year (Y1), and then annually. They were classified as grade I (IGF-1 level normal-for-age and positive GH response on oral glucose tolerance test [nadir <0.4ng/L]); grade II (discordant); or grade III or IV (acromegaly, controlled or uncontrolled under medical therapy, respectively). RESULTS: Taking all patients with all grades, 35% changed grades between EPP and M3, 26% between M3 and Y1 and 9% after Y1. In grade I, respectively 22%, 15% and 2% of patients changed grades between EPP and M3, between M3 and Y1, and after Y1, compared to 31%, 6% and 6% in grade IV. Respectively 57%, 67%, and 47% of grade II patients changed grades between EPP and M3, between M3 and Y1, and after Y1; between EPP or M3 and last follow-up (>1 year), respectively 74% and 75% of grade II patients changed grades. Knosp category, resection quality and abnormal GH response (vs. abnormal IGF-1) significantly impacted grade II patients' outcome. CONCLUSIONS: Whereas outcome in grades I and III-IV seems to be determined by 1 year, grade II discordant patients' outcome remains uncertain even after 1 year.

RESUMO

PURPOSE: Surgical indications for pituitary tumors during pregnancy are rare, and are derived from a balance between expected benefits, particularly for maternal benefits, and anesthetic/surgical risks. METHODS: A literature review was performed to define the optimal surgical indications for pituitary adenomas (PA) and other pituitary tumors during pregnancy. RESULTS: Main benefits are expected in case of critical visual impairment and/or life-threatening endocrine disturbances. Multidisciplinary patient management is systematically required although nonobstetric surgery presents a reasonable risk during pregnancy. The risks of congenital malformation during the first trimester and those of premature birth during the third trimester make the second trimester the optimal period for surgery. In prolactin-secreting, nonsecreting, GH- and TSH-secreting PAs, transsphenoidal surgery (TS) is recommended in cases involving severe visual impairment, characterized by severe visual field deficit, visual acuity impairment, and abnormal optical coherence tomography findings, and when no other medical alternatives are possible and/or sufficient. Uncontrolled and severe Cushing's disease (CD) during pregnancy increases both maternal and fetal morbimortality, thus justifying TS or sometimes dopamine agonist therapy as a safer alternative. Finally, metyrapone, ketoconazole, or bilateral adrenalectomy could be recommended in certain cases after the failure of medical therapies and/or TS. Surgery is also required for suprasellar meningiomas, craniopharyngiomas, and pituitary cysts in the case of severe visual deficit. CONCLUSION: Surgical indications for pituitary tumors are rare during pregnancy; therefore, surgery should be avoided when possible. Further, the second trimester should be considered as the optimal surgical period. Severe visual disturbance and uncontrolled CD are the main surgical indications during pregnancy.
