Depression, anxiety, body image scores, and sexual dysfunction in patients with polycystic ovary syndrome according to phenotypes.

Background: Polycystic ovary syndrome (PCOS) has been linked to both mental and metabolic disturbances. The purpose of this research was to investigate psychological features such as anxiety and depression, body image, sexual dysfunction, and associated factors among the PCOS phenotypes and to compare these with healthy controls. Methods: The study involved 167 reproductive-age women with PCOS and 73 healthy controls. Standardized scales assessing depression (the Beck Depression Inventory [BDI]), depression and anxiety (the Hospital Anxiety and Depression Scale [HADS] and the General Health Questionnaire [GHQ]), and body image scale (the Body Cathexis Scale [BCS]) were administered to all participants. Hirsutism scores, serum androgen levels, and metabolic parameters were recorded. Results: Significantly higher BDI, HADS depression, and GHQ scores, and a more negative body image in terms of BCS scores were observed in the women with PCOS than in the healthy controls. BDI scores were significantly higher in phenotypes A, B, and D compared with the healthy controls. No significant difference was observed in BDI and HADS depression scores among the phenotypes. Significant differences were observed only between phenotype A and the control group in terms of HADS depression and GHQ scores. BCS scores were significantly higher in phenotypes A, B, and C than in the healthy controls. No significant difference was determined in Female Sexual Function Index (FSFI) scores between the PCOS phenotypes and the healthy controls. When all participants were divided into three groups based on body mass index (BMI), a statistically significant difference was observed only between the phenotype A lean group (BMI: 18.5-24.9 kg/m2) and the control group in terms of BDI, HADS depression, and BCS scores. Conclusions: BDI, HADS depression scores, and GHQ scores were all higher in patients with PCOS compared with the healthy controls. These features were more pronounced in phenotypes A and B, including hyperandrogenism and oligo-anovulation. Physicians should be aware of the high risk of these disorders in women with PCOS.

Investigation of VEGF and IL-8 Gene Polymorphisms in Patients with Differentiated Thyroid Cancer.

BACKGROUND: Differentiated thyroid carcinomas (DTC) account for most of the thyroid cancers. The emergence of DTC may be affected by various predisposing genetic alterations and environmental factors The aim of this study was to investigate the role of VEGF C936T and IL-8 A251T gene polymorphisms in the pathogenesis and metastasis of differentiated thyroid cancer. METHODS: The study consisted of 101 patients DTC patients and 109 healthy controls. The parameters of the stage of cancer of the DTC patients at the time of diagnosis (TNM) were recorded. DNA was isolated from blood using a DNA isolation kit. VEGF C936T and IL-8 A251T gene polymorphisms were determined using the polymerase chain reaction (PCR) and restriction fragment length polymorphism (RFLP) methods. Distributions of gene polymorphisms were evaluated according to the Hardy-Weinberg principle. RESULTS: The TT genotype from the VEGF C936T genotype distributions was higher in the control group than in the DTC group (p < 0.05). In contrast, the IL-8 A-251T genotype distributions were similar in both groups. No relationship was found between either cytokine gene polymorphism or the DTC stages. The frequency of IL-8 TT was higher in the DTC group with lymph gland metastasis (TT 92%) than in the group without lymph gland metastasis (TT 45.9%) (p < 0.05). CONCLUSIONS: We consider that the VEGF 936 TT genotype may play a protective role in the development of DTC and that the IL-8 A-251 TT genotype may contribute to the DTC lymph node metastasis. Therefore, these genotypes may hold a key to the evaluation of thyroid nodules and the metastasis of DTC.

Investigation of insulin resistance gene polymorphisms in patients with differentiated thyroid cancer.

We aimed to investigate insulin receptor substrate-1 (IRS-1), insulin receptor substrate-2 (IRS-2), insulin-like growth factor binding protein-3 (IGFBP-3) genotypes, which are thought to be involved in the pathogenesis of many solid tumors and have thus far not been studied in patients with differentiated thyroid cancer (DTC). The study consisted of 93 patients diagnosed with DTC (79 females, 14 males) and 111 healthy control subjects (63 females, 48 males). The anthropometric measurements, lipid profiles, thyroid function tests and homeostatic model assessment (HOMA) as an indicator of insulin resistance (IR) of all patients were recorded. In addition IRS-1, IRS-2 and IGFBP-3 gene polymorphisms were determined by using polymerase chain reaction and restriction fragment length polymorphism. Hardy-Weinberg equilibrium was tested for each gene polymorphisms, and genetic effects were evaluated by the Chi Square test and multiple logistic regression. Homeostasis model assessment of insulin resistance (HOMA-IR), body mass index, waist circumference and serum total cholesterol levels were significantly higher in patients with DTC than in the control group. There was no difference between the two groups with respect to IRS-1, IRS-2 and IGFBP-3 gene polymorphisms. In addition, these gene polymorphisms were found to have no effect on lymph node metastases or tumor staging. While, obesity and increased HOMA-IR may be risk factors in DTC development, we suggest that IRS-1, IRS-2 and IGFBP-3 gene polymorphisms do not play an important role in pathogenesis of DTC.

Pheochromocytoma presenting with rhabdomyolysis and acute renal failure: a case report.

Rhabdomyolysis ranges from an asymptomatic illness with elevated creatine kinase levels to a life-threatening condition associated with extreme elevations in creatine kinase, electrolyte imbalances, acute renal failure, and disseminated intravascular coagulation. The most common causes are crush injury, overexertion, alcohol abuse, certain medicines, and toxic substances. A number of electrolyte abnormalities and endocrinopathies, including hypothyroidism, thyrotoxicosis, diabetic ketoacidosis, nonketotic hyperosmolar state, and hyperaldosteronism, cause rhabdomyolysis. Rhabdomyolysis and acute renal failure are unusual manifestations of pheochromocytoma. There are a few case reports with pheochromocytoma presenting rhabdomyolysis and acute renal failure. Herein, we report a case with pheochromocytoma crisis presenting with rhabdomyolysis and acute renal failure.

Machine Learning May Be An Alternative To BIPSS In The Differential Diagnosis Of ACTH-Dependent Cushing's Syndrome.

OBJECTIVE: This study aimed to develop machine learning (ML) algorithms for the differential diagnosis of adrenocorticotropic hormone (ACTH)-dependent Cushing's syndrome (CS) based on biochemical and radiological features. METHODS: Logistic regression algorithms were used for ML, and the area under the receiver operating characteristics curve (AUROC) was used to measure performance. We used Shapley Contributed Comments (SHAP) values, which help explain the results of the ML models to identify the meaning of each feature and facilitate interpretation. RESULTS: A total of 106 patients, 80 with Cushing's disease (CD) and 26 with ectopic ACTH syndrome (EAS), were enrolled in the study. The ML task was created to classify patients with ACTH-dependent CS into CD and EAS. The average AUROC value obtained in the cross-validation of the logistic regression model created for the classification task was 0.850. The diagnostic accuracy of the algorithm was 86%. The SHAP values indicated that the most important determinants for the model were the 2-day 2-mg dexamethasone suppression test, the > 50% suppression in the 8-mg high-dose dexamethasone test, late-night salivary cortisol, and the diameter of the pituitary adenoma. We have also made our algorithm available to all clinicians via a user-friendly interface. CONCLUSION: ML algorithms have the potential to serve as an alternative decision support tool to invasive procedures in the differential diagnosis of ACTH-dependent CS.

Reliability of the diagnostic tests for Cushing's syndrome performed in a tertiary referral center.

The study aimed to retrospectively evaluate the reliability of the diagnostic and location tests in Cushing's Syndrome (CS). Eighty-seven patients diagnosed with CS between 1995 and 2007 by Endocrinology Metabolism Department of Cerrahpasa Medical School were included in the study. The control group consisted of 91 patients who presented to the outpatient clinic because of obesity. The diagnostic tests were as follows: 1 mg dexamethasone suppression test (DST), 24-h urinary free cortisol (UFC), midnight cortisol level (MCL), ACTH level and overnight 8 mg DST. The sensitivity and specificity of UFC were 81 and 66 % respectively for the cut-off point of 50 µg/day, whereas they were 64 and 76 % respectively for the cut-off point of 100 µg/day. For the cut-off value of 1.8/µg/dL for MCL and 1 mDST, the sensitivity rates were 100 and 98 %, while the specificity rates were 88 and 33 %, respectively. Among the location tests, the sensitivity and specificity of ACTH under 10 pg/mL for adrenal CS were 92 and 94 % respectively. The sensitivity and specificity of ACTH higher than 30 pg/mL for ACTH-dependent CS were 69 and 100 % respectively. The sensitivity rates of 8 mg DST for 50 and 60 % suppressions were 83 and 79 % respectively, whereas the specificity rates were 75 and 88 % respectively. 1 mg DST (cut-off <1.8 µg/dL) and UFC (50 µg/24 h) are appropriate tests for screening CS. Overnight 8 mg DST with 60 % suppression for Cushing's Disease (CD) and ACTH levels <10 pg/mL for adrenal CS, ACTH levels >30 pg/mL for ACTH dependency were identified as the best tests for the differential diagnosis of the subtypes.

Evaluation of depression, quality of life and body image in patients with Cushing's disease.

The aim of this study was to evaluate patients with Cushing's disease (CD) who had undergone transsphenoidal surgery in terms of depression, quality of life (QoL), and perception of body image in comparison to healthy controls. Forty patients with CD and 40 healthy controls matched for demographic characteristics were included in the study. The subjects were evaluated with the Beck depression inventory (BDI), the health survey-short form (SF-36) and the multidimensional body-self relations questionnaire (MBSRQ). Subgroups of the patients with CD were formed on the basis of remission status and BDI scores. In this study, QoL in the general health category and body image were lower in the patients with CD than in the healthy subjects. However, no differences in depression scores were found between the two groups. When the CD group was evaluated according to remission rate, the mean BDI score was significantly higher in the CD patients without remission than in both the CD patients with remission and the healthy subjects (p = 0.04). However, the physical functioning, bodily pain and general health scores of the CD patients without remission on the SF-36 questionnaire were lower than in the CD patients in remission and the healthy subjects (p = 0.002, p = 0.04, p = 0.002, respectively). Fitness evaluation, health evaluation and body areas satisfaction scores of the MBSRQ were significantly different in the three groups (p = 0.003, p = 0.009 and p = 0.001, respectively). In this study, patients with CD were found to have lower QoL, lower body image perception and higher levels of depression compared to healthy controls, particularly if the disease is persistant despite surgery.

Aromatase cytochrome P450 enzyme expression in prolactinomas and its relationship to tumor behavior.

The aim of the study was to evaluate the presence of aromatase cytochrome P450 enzyme (P450AROM) expression in normal pituitary tissues and tumor tissues of patients with prolactinoma and to examine the impact of the P450AROM expression on clinical outcome. Twenty-six consecutive human pituitary tissue samples were obtained from autopsies performed at the Institute of Forensic Medicine. Sixty-four patients who had an adenomectomy between 2000 and 2009 after prolactinoma diagnosis with histologically confirmed pituitary tumor tissues were retrospectively included in this study. The slices from the pituitary tissues were subjected to immunohistochemical staining for evaluation of P450AROM and estrogen receptor beta (ER beta) subunit. Immunohistochemistry results were compared according to age, gender, remission rate, resistance and invasion status of the patients. Higher than normal P450AROM expression was found in the pituitary tissues of the patients with prolactinoma (p < 0.001). P450AROM intensity had no relation to resistance or remission in patients with prolactinoma (p = 0.44, p = 0.45, respectively). The subgroup analysis showed that compared to males without invasive adenoma, males with invasive adenoma had higher P450AROM expression (p = 0.048). ER beta was found to have an impact on resistance (p = 0.049). This study shows that P450AROM expression is present in the pituitary tissues of patients with prolactinoma and that this presence could be important in development and tumor behavior of prolactinomas.

Acromegaly is associated with higher frequency of female sexual dysfunction: experience of a single center.

The aim of the study was to assess female sexual dysfunction (FSD), quality of life and depression status in female patients with acromegaly. Fifty-seven sexually active female patients with acromegaly disease (21 controlled, 36 uncontrolled) monitored by Cerrahpasa Medical School, Endocrinology and Metabolism out-patient clinic and age and body mass index-matched 46 healthy female subjects were included in the study. Sexual functions and status of depression in both patient and control groups were evaluated by using the Female Sexual Function Index Form (FSFI) and the Beck Depression Inventory (BDI), respectively. Quality of life was evaluated by using the Acromegaly Quality of Life (AcroQoL) Scale. Hormone levels were studied in the groups. The FSFI total score and desire, arousal, orgasm, and satisfaction domains in patients with acromegaly were significantly lower than in the healthy controls (p ≤ 0.0001). There was no difference between biochemically controlled and uncontrolled patients with acromegaly with respect to FSFI scores (p = 0.7). AcroQoL total score in female patients with controlled acromegaly and uncontrolled acromegaly were 46.33 ± 16.5% and 50.13 ± 18.21%, respectively (p = 0.53). The difference in BDI scores between controlled and uncontrolled acromegaly patients was not significant but they were significantly higher in the control group (p ≤ 0.0001). In the correlation analysis, a negative correlation was found between FSFI total and BDI score (r = -0.69, p< 0.001), age (r = -0.45, p< 0.001), and IGF-I (r = -0.28, p = 0.006). This study showed that sexual dysfunction and depression rates in female patients with acromegaly are higher than in healthy females.

Acromegaly is not associated with irritable bowel syndrome: a pilot study.

BACKGROUND: In acromegaly, the gastrointestinal system is under the influence of excessive growth hormone (GH) and insulin like growth factor-1 (IGF-I). Increased bowel length and delayed transit time may cause functional disturbance of the bowel. The objective of the current study is to evaluate the frequency of irritable bowel syndrome (IBS) in cases with acromegaly. PATIENTS AND METHODS: Twenty-three active cases with acromegaly newly diagnosed between 2010-2011 were included in the study. The control group consisted of ninety gender and age-matched healthy controls (HC). All cases were questioned for presence of IBS using Rome III criteria. Abdominal ultrasonography and colonoscopy results of acromegalic patients were obtained. In addition, cases with acromegaly were evaluated for their quality of life and status of depression by using the Acromegaly Quality of Life Questionnaire (AcroQoL) and Beck Depression Inventory (BDI), respectively. RESULTS: The median GH and IGF-1 levels of cases with acromegaly were 5.72 [IQR: 2.2-34] ng/ml and 753 [IQR: 503-1050] ng/ml, respectively. The median AcroQoL score of patients with acromegaly was 56 [IQR: 43-71.5] and the median BDI score was 16 [IQR: 11-21]. Rome III diagnostic criteria were positive in 2 of 23 acromegaly patients and in 3 of 90 HC (p=0.26). IBS was present in 1 of 23 of the acromegaly patients compared to 3 of 90 HC (p=0.81). CONCLUSION: Although acromegaly and IBS may cause similar gastrointestinal symptoms, acromegaly is not associated with a greater incidence of true IBS.

Effect of stressful life events on the initiation of graves' disease.

OBJECTIVE: The aim of this study was to investigate the relationship between stressful life events (LESs) and its effect on the initiation of Graves' disease (GD) and toxic nodular goitre (TNG). PATIENTS AND METHOD: Forty-five patients with GD, 24 patients with TNG and 36 healthy control (CG) were included to the study. Graves and TNG patients had diagnosed within the last 12 months, with clinical and biochemical confirmation in Endocrinology Metabolism Outpatient Clinic of Cerrahpasa Medical School. The Holmes-Rahe Stress Scale and the Life Experience Survey (LES) was the psychological evaluation instrument used in this study. RESULTS: There was no significant difference according to Holmes-Rahe scale (Graves & TNG P = 0.329, Graves & Control P = 0.115, TNG and control P = 0.571). According to LES scale when negative event number, positive event number, neutral events and their effects are considered, between Graves and TNG groups no statistically difference was observed (P = 0.139, P = 0.083, P = 0.167, P = 0.162, P = 0.861). The number and impact of negative SLEs were significantly higher in GD compared to CG (P = 0.015, P < 0.001). CONCLUSION: According to LES scale GD patients has significant difference with respect to CG when negative event number and impact are considered.

Management of endocrine surgical disorders during COVID-19 pandemic: expert opinion for non-surgical options.

PURPOSE: The COVID-19 pandemic brought unprecedented conditions for overall health care systems by restricting resources for non-COVID-19 patients. As the burden of the disease escalates, routine elective surgeries are being cancelled. The aim of this paper was to provide a guideline for management of endocrine surgical disorders during a pandemic. METHODS: We used Delphi method with a nine-scale Likert scale on two rounds of voting involving 64 experienced eminent surgeons and endocrinologists who had the necessary experience to provide insight on endocrine disorder management. All voting was done by email using a standard questionnaire. RESULTS: Overall, 37 recommendations were voted on. In two rounds, all recommendations reached an agreement and were either endorsed or rejected. Endorsed statements include dietary change in primary hyperparathyroidism, Cinacalcet treatment in secondary hyperparathyroidism, alpha-blocker administration for pheochromocytoma, methimazole ± ß-blocker combination for Graves' disease, and follow-up for fine-needle aspiration results of thyroid nodules indicated as Bethesda 3-4 cytological results and papillary microcarcinoma. CONCLUSION: This survey summarizes expert opinion for the management of endocrine surgical conditions during unprecedented times when access to surgical treatment is severely disrupted. The statements are not applicable in circumstances in which surgical treatment is possible.

Ornithine transcarbamylase deficiency diagnosed in pregnancy.

Urea cycle enzymes deficiencies are rare metabolic disorders. Ornithine transcarbamylase (OTC) deficiency is the most common type. The syndrome results from a deficiency of the mitochondrial enzyme OTC which catalyses the conversion of ornithine and carbamoyl phosphate to citrulline. It shows X-linked inheritance and typically remains asymptomatic until late infancy or early childhood. The severity of the symptoms depends on the age of the patient and the duration of hyperammonemia. Female heterozygotes are more difficult to diagnose. They suffer from hyperammonemic periods which can be triggered by trauma, infections, surgery, childbirth, parenteral nutrition, and by the initiation of sodium valproate therapy. The prognosis of OTC deficiency is better for those with an onset after infancy, but morbidity from brain damage does not appear to be linked to the number of episodes of hyperammonemia that have occurred. However, early diagnosis and prompt initiation of ammonia-lowering treatment are essential for survival of these patients. This case presents a patient who was diagnosed with OTC deficiency following mental confusion during pregnancy.

An overview of polycystic ovary syndrome in aging women

The manifestations of polycystic ovary syndrome (PCOS), a ubiquitous reproductive disorder, may vary significantly depending on the severity of a number of endocrine and metabolic changes. Although no diagnostic criteria are presently available for PCOS for perimenopausal and menopausal women, the condition can still be suspected in case of a previous diagnosis of the condition, a chronic history of irregular menstrual cycles and hyperandrogenism, and/or polycystic ovarian morphology during the reproductive period. PCOS is associated with long-term health risks, including obesity, diabetes, hypertension, dyslipidemia, metabolic syndrome and cardiovascular risk factors during reproductive age, especially in patients possessing classic phenotypes. The aim of this review was to outline the available data about the impact of PCOS on long-term health risks after reproductive age in patients with PCOS. Previously, it was assumed that women with PCOS would be more prone to develop cardiometabolic diseases after reproductive age but current data suggest that in accordance with the healing in the phenotypic characteristics of PCOS, no deterioration appears to occur in cardiometabolic health in these patients. While there is substantial evidence for a greater prevalence of abnormal subclinical atherosclerotic markers among younger patients with PCOS, data for older women are insufficient. However, there is also support for an increased risk of endometrial cancer in PCOS patients. Extensive prospective cohort studies in which healthy controls as well as patients with defining PCOS phenotypes are observed and monitored from the early reproductive period into the late postmenopausal period should now be performed in order to clarify morbidities and mortality in aging women with PCOS.

Obesity and physical exercise.

Obesity represents a major health problem worldwide and is associated with increased prevalence of numerous health-related conditions, including diabetes, hypertension, cardiovascular disease, some forms of cancer and musculoskeletal disorders, among others. Studies that have examined the impact of physical exercise combined with energy restriction diets on weight have shown greater weight loss compared to interventions of exercise-only. Accordingly, the most effective approach to achieve significant weight loss includes a combination of diet, exercise and behavioral strategies. Current guidelines recommend participating in at least 150 minutes of moderate-intensity or 75 minutes of vigorous intensity aerobic exercise weekly, and resistance/muscle strengthening training, involving all major muscle groups at least twice a week. For patients seeking to maintain weight loss, high levels of exercise (225-420 min/week of moderate intensity exercise) have been associated with improved weight maintenance compared to lower levels (<150 min/week). Weight loss has been associated with improvements in prevalence and severity of several obesity associated comorbidities such as insulin resistance, inflammation, dyslipidemia, hypertension, metabolic syndrome, diabetes, pulmonary disease and cardiovascular disease. This review summarized the current knowledge regarding the role of exercise in prevention of weight gain, weight loss and maintenance of weight loss in obese individuals, also outlining the data on effects of exercise on complications of obesity and highlighting areas for future research.

Long-term results of coronary surgery with endoscopic vein harvesting.

BACKGROUND: In this study, we aimed to evaluate early and longterm outcomes of both isolated or concomitant coronary artery bypass grafting with the endoscopic vein harvesting technique. METHODS: Between November 2012 and May 2017, a total of 324 patients (259 males, 65 females; mean age: 63.2±9.8 years; range, 36 to 91 years) who underwent coronary artery bypass grafting, with or without concomitant procedures, using the endoscopic vein harvesting technique were retrospectively analyzed. Early postoperative outcomes and long-term follow-up data of the patients, such as cardiovascular or cerebral events, cardiac reinterventions, and the images of coronary angiography were recorded. RESULTS: Median logistic EuroSCORE and in hospital mortality was 3.99 (0.8-81) vs. 0 .9% f or i solated c oronary surgery and 13.34 (1.5-76.4) vs. 1.5% for concomitant procedures. The long-term data could be obtained in 288 patients with a median of 59.6 (7-90) months of follow-up. During this period, 22 (7.6%) patients underwent coronary angiography for control or treatment, 12 (4.2%) patients needed revascularization, and none of the patients underwent redo coronary surgery. CONCLUSION: Our study results suggest that the endoscopic vein harvesting technique during coronary artery bypass grafting is safe in experienced hands.

Effects of Treatment Adherence on Quality of Life in Hypoparathyroid Patients.

OBJECTIVES: This study aimed to evaluate the current situation of hypoparathyroid patients and to investigate the relationship between treatment adherence and quality of life. STUDY DESIGN: Prospective, multicentre study. METHODS: Adult patients presenting with the diagnosis of hypoparathyroidism to 20 different endocrinology clinics were included. They were receiving conventional therapies for hypoparathyroidism, using calcium, active vitamin D, and magnesium. We collected data on demographic features, disease- and treatment-related information, and results of routine laboratory tests, treatment adherence, and presence of complications. Beck Depression Inventory, Beck Anxiety Inventory, and Short Form-36 quality of life assessments were administered. RESULTS: Among the 300 patients studied, 60.7% were adherent to their treatment, and 34.1% had complications. Anxiety and depression scores were significantly higher in non-adherent versus treatment-adherent patients (p<0.001 and p=0.001, respectively). Most of the domains of quality-of-life scores were also significantly lower in non-adherent patients. Both anxiety and depression scores showed significant, negative correlations with serum calcium and magnesium concentrations (r=-0.336, p<0.001 and r=-0.258, p<0.001, respectively). CONCLUSIONS: Nearly 40% of the patients were non-adherent to conventional treatment for hypoparathyroidism, and such patients had higher anxiety and depression scores and poorer quality of life scores. Conventional treatment might not be sufficient to meet the needs of patients with hypoparathyroidism. In addition to seeking new therapeutic options, factors influencing quality of life should also be investigated and strategies to improve treatment adherence should be developed.

Thyroid cancer is the most common cancer associated with acromegaly.

The aim of the study was to screen the malignancy in an acromegalic patient group and to determine whether there was any increased risk and the incidence of malignancy and its association with disease characteristics such as duration of disease, latency in diagnosis, and GH and IGF-1 levels. One hundred-five (65 female, 40 male) patients with acromegaly followed and treated at Cerrahpasa Medical School, Endocrinology and Metabolism outpatient clinic between 1983 and 2007 were included in this study. The patients were screened with colonoscopy, mammography, and thyroid and prostate ultrasonography (US). Malignancy was detected in 16 (15%) patients. Thyroid cancer was found in 5 patients (4.7%), breast cancer in 3 (2.8%), colon cancer in 2 (1.9%), lung cancer in 2 (1.9%), cervix cancer in 1 (0.9%), myelodysplastic syndrome (MDS) in 1 (0.9%), cholangiocarcinoma in 1 (0.9%), and multiple endocrine neoplasm (MEN) type 1 in 1 patient (0.9%). Cancer was more common in the male patients (P = 0.046) and high levels of GH increased the risk of cancer development (P = 0.046). In this series, the most commonly detected cancer types were thyroid followed by breast and colon cancers. Although high levels of initial GH seemed to increase the risk of cancer development in acromegalic patients, age, gender, age at the time of diagnosis, duration of disease, and initial IGF-I levels were not associated with cancer development.
