RESUMEN
OBJECTIVE: Cancer incidence in patients with endogenous Cushing's syndrome (CS) has never been established. Here, we aimed to assess the cancer risk in patients with CS as compared with individually matched controls. DESIGN: A nationwide retrospective matched cohort study of patients with endogenous CS diagnosed between 2000 and 2023 using the database of Clalit Health Services in Israel. METHODS: Patients with adrenal carcinoma or ectopic CS were excluded. Patients with CS were matched in a 1:5 ratio, with controls individually matched for age, sex, socioeconomic status, and body mass index. The primary outcome was defined as the first diagnosis of any malignancy following a CS diagnosis. Risk of malignancy was calculated using the Cox proportional hazard model, with death as a competing event. RESULTS: A total of 609 patients with CS and 3018 controls were included [mean age at diagnosis, 48.0 ± 17.2â years; 2371 (65.4%) women]. The median follow-up was 14.7â years (IQR, 9.9-20.2â years). Patients with CS had an increased cancer risk, with a hazard ratio (HR) of 1.78 (95% CI 1.44-2.20) compared with their matched controls. The risk of malignancy was elevated in patients with Cushing's disease (251 cases and 1246 controls; HR 1.65, 95% CI 1.15-2.36) and in patients with adrenal CS (200 cases and 991 controls; HR 2.36, 95% CI 1.70-3.29). The increased cancer risk in patients with CS persists after exclusion of thyroid malignancies. CONCLUSION: Endogenous CS is associated with increased malignancy risk. These findings underscore the need for further research to establish recommendations for cancer screening in this population.

PURPOSE: The study aimed to characterize the erythrocytic profile in patients with cushing's syndrome (CS) versus controls from the normal population according to etiology, sex, presence of diabetes mellitus (DM) and hypercortisolemia remission status. METHODS: This retrospective cohort analysis compared erythrocytic parameters between patients with CS of pituitary (CD) and adrenal (aCS) etiology and age, sex, body mass index (BMI) and socioeconomic status-matched controls in a 1:5 ratio. Laboratory values at baseline were calculated as mean values during the year preceding CS diagnosis, and over one year thereafter. RESULTS: The cohort included 397 CS patients (68.26% female; mean age 51.11 ± 16.85 years) and 1970 controls. Patients with CS had significantly higher baseline median levels of hemoglobin (Hgb) (13.70 g/dL vs. 13.12 g/dL [p < 0.0001]) and hematocrit (Hct) (41.64% vs. 39.80% [p < 0.0001]) compared to controls. These differences were observed for both CD and aCS and for both sexes. Patients who attained remission had Hgb and Hct levels comparable to controls (13.20 g/dL and 40.08% in patients with CD and aCS vs. 13.20 g/dL and 39.98% in controls). Meanwhile, those with persistent/recurrent disease maintained elevated levels. Patients with comorbid DM had similar Hgb but higher Hct (p = 0.0419), while patients without DM showed elevated erythrocytic values compared to controls (p < 0.0001). CONCLUSION: Our data illustrates that erythrocytic parameters are directly influenced by glucocorticoid excess as Hgb and Hct are higher in patients with CS, and normalize after remission. We have identified the influence of DM on erythrocytic parameters in patients with CS for the first time.

OBJECTIVE: To evaluate the clinical presentation, biochemical profile, and etiology of Cushing's syndrome (CS) in women stratified by age. METHODS: Retrospective study of patients with CS, treated at Rabin Medical Center from 2000 to 2020, or Maccabi Healthcare Services in Israel from 2005 to 2017. Disease etiology, presentation and biochemical profile were compared according to age at diagnosis: ≤ 45, 46-64, or ≥ 65 years. Study was approved by the Ethics Review Boards of both facilities with waiver of consent. RESULTS: The cohort included 142 women (mean age, 46.0 ± 15.1 years):81 (57.0%) with Cushing's disease (CD), and 61 (43.0%) with adrenal CS. Pituitary etiology was more common among women < 45 (70.6%), compared with patients ≥ 65 years (31.6%) (P < 0.05). Among CS patients, hypercortisolism was diagnosed in the context of screening after an adrenal incidentaloma detection in 15.0% of patients < 45 and 53.8% of ≥ 65 years (P < 0.001). Weight gain was evident in 57.4% of women < 45 (56.3% CD, 60.0% CS), and 15.8% of women ≥ 65 years (50% CD, 0% CS) (P = 0.011). Mean UFC levels were highest for women < 45 (3.8 × ULN) and lowest for ≥ 65 years (2.3 × ULN) (P < 0.001). CONCLUSION: We have shown for the first time that women with CS ≥ 65 years of age more commonly have adrenal etiology. The initial presentation of CS also differs between age groups, where women < 45 years are likely to present with weight gain, while those ≥ 65 years are frequently diagnosed incidentally, when screening for hypercortisolism in the presence of an adrenal incidentaloma.
