ABSTRACT

PURPOSE: In adults and children, transsphenoidal surgery (TSS) represents the cornerstone of management for most large or functioning sellar lesions with the exception of prolactinomas. Endocrine evaluation and management are an essential part of perioperative care. However, the details of endocrine assessment and care are not universally agreed upon. METHODS: To build consensus on the endocrine evaluation and management of adults undergoing TSS, a Delphi process was used. Thirty-five statements were developed by the Pituitary Society's Education Committee. Fifty-five pituitary endocrinologists, all members of the Pituitary Society, were invited to participate in two Delphi rounds and rate their extent of agreement with statements pertaining to perioperative endocrine evaluation and management, using a Likert-type scale. Anonymized data on the proportion of panelists' agreeing with each item were summarized. A list of items that achieved consensus, based on predefined criteria, was tabulated. RESULTS: Strong consensus (≥ 80% of panelists rating their agreement as 6-7 on a scale from 1 to 7) was achieved for 68.6% (24/35) items. If less strict agreement criteria were applied (ratings 5-7 on the Likert-type scale), consensus was achieved for 88% (31/35) items. CONCLUSIONS: We achieved consensus on a large majority of items pertaining to perioperative endocrine evaluation and management using a Delphi process. This provides an international real-world clinical perspective from an expert group and facilitates a framework for future guideline development. Some of the items for which consensus was not reached, including the assessment of immediate postoperative remission in acromegaly or Cushing's disease, represent areas where further research is needed.

ABSTRACT

PURPOSE: Current international guidelines recommend colonoscopy in patients with acromegaly at the time of diagnosis, even though the risk of developing colorectal neoplasm is still controversial. The main objective of this Argentine multicenter study was to analyze through screening colonoscopy the presence of advanced neoplastic lesions considered as precancerous, in patients with acromegaly compared to a control group. METHODS: This is a case-control retrospective study. Full length colonoscopy of 70 acromegalic patients and 128 control subjects were studied. Polyps were classified into non pre-cancerous lesions and advance neoplastic lesions which included advanced adenomas (preneoplastic) and colorectal carcinomas. RESULTS: Thirty three out of 70 acromegalic patients and 32 out of 128 subjects controls presented polyps in the colonoscopy [47.1% vs 25%, p = 0.002, OR 2.68]. Non precancerous polyps were found in 11 (15.7%) and 23 (17.9%) (p = 0.690), while advanced neoplastic lesions were found in 22 (31.4%) and 9 (7.0%) (p = 0,0001 - OR: 6.06) patients and controls respectively. Advanced adenomas and colorectal carcinomas were found in 18 (27.3%) and 9 (7.0%) (p = 0,0006-OR: 4,57), and 4 (5.7%) and 0 (0.0%) p = 0.0063) of patients and controls respectively. The presence of insulin resistance was the only statistically significant associated factor among acromegalic patients with and without colonic polyps. CONCLUSIONS: Our findings show an increased risk of preneoplastic colonic lesions and colorectal carcinoma in patients with chronic and sustained GH excess compared to a control group. This supports the recommendation to perform screening colonoscopy at diagnosis of acromegaly.

ABSTRACT

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the viral strain that has caused the coronavirus disease 2019 (COVID-19) pandemic, has presented healthcare systems around the world with an unprecedented challenge. In locations with significant rates of viral transmission, social distancing measures and enforced 'lockdowns' are the new 'norm' as governments try to prevent healthcare services from being overwhelmed. However, with these measures have come important challenges for the delivery of existing services for other diseases and conditions. The clinical care of patients with pituitary disorders typically involves a multidisciplinary team, working in concert to deliver timely, often complex, disease investigation and management, including pituitary surgery. COVID-19 has brought about major disruption to such services, limiting access to care and opportunities for testing (both laboratory and radiological), and dramatically reducing the ability to safely undertake transsphenoidal surgery. In the absence of clinical trials to guide management of patients with pituitary disease during the COVID-19 pandemic, herein the Professional Education Committee of the Pituitary Society proposes guidance for continued safe management and care of this population.

ABSTRACT

Introducción: El riesgo de desarrollar neoplasias colónicas en pacientes acromegálicos y su relación directa con los niveles elevados de GH/IGF-1 no están bien establecidos y continúan siendo motivo de controversia en la literatura mundial. El objetivo de este trabajo fue evaluar el riesgo de desarrollar lesiones neoplásicas avanzadas (LNA) (adenomas mayores a 1 cm, componente velloso mayor del 75% y/o displasia de alto grado), en pacientes con acromegalia, comparado con un grupo control. Materiales y métodos: Estudio multicéntrico caso-control retrospectivo. Ciento treinta y siete pacientes con acromegalia que realizaron videocolonoscopia (VCC) fueron incluidos inicialmente, aunque solo 69 cumplieron criterios de inclusión. Sesenta y dos controles fueron obtenidos: por cada caso (paciente con acromegalia) 2 «controles¼ fueron seleccionados aleatorizadamente e igualados por edad y sexo. El riesgo se expresó en odds ratio (OR) y su correspondiente intervalo de confianza (IC) del 95%. La significación estadística fue considerada una p < 0,05. Resultados: De los 69 pacientes con VCC completa y datos adecuados para su análisis, 28 presentaron VCC positiva con hallazgos de pólipos (40%) y 41 VCC negativa o normal (60%). Dentro del grupo con VCC positiva, 14 presentaron LNA (20%) y solo un paciente presentó diagnóstico de cáncer colorrectal. Para el análisis caso-control se incluyó a 31 pacientes frente al grupo control (n = 62) que cumplieron con los criterios de inclusión. La presencia de pólipos colónicos, adenomas y LNA en los pacientes con acromegalia fue de 19/31 (61,9%), 14/31 (45,16%) y 10/31 (32,25%), y en el grupo control de 18/62 (29,03%), 11/62 (17,74%) y 4/62 (6,45%), respectivamente. El riesgo de adenomas y LNA fue mayor en el grupo de acromegalia en comparación con el grupo control, siendo ambos resultados estadísticamente significativos: adenomas OR 2,54 (IC 1,22-5,25) p = 0,005, LNA OR: 7,3 (2,4-25), p = 0,00. Conclusión: La acromegalia se asocia a un mayor riesgo de lesiones colónicas preneoplásicas. Este hallazgo justifica el cribado con VCC al diagnóstico en pacientes con acromegalia.


Background: The risk of developing cancerous lesions in the colon of acromegaly patients and their direct relationship with elevated growth hormone (GH) and insulin-like growth factor-1 (IGF-1) levels is not well established, and is still controversial in the international literature. The objective of this study was to evaluate the risk of developing advanced neoplastic lesions (ALN: greater than 1 cm adenomas, villous component greater than 75% and/or high grade dysplasia) in patients with acromegaly compared to a control group. Materials and methods: A multicentre, retrospective case-control study was conducted initially on 137 patients with acromegaly (cases) who underwent videocolonoscopy (VCC), although only 69 met inclusion criteria. Sixty-two controls were obtained, and for each case two "controls" were randomly selected and matched by age and gender. Risk was expressed as odds ratio (OR) and its corresponding 95% con"dence interval (CI). P values < .05 were considered statistical significantly. Results: Of the 69 acromegaly patients with a completed VCC and adequate data for their analysis, 28 had a positive VCC with findings of polyps (40%), and 41 VCC negative with no lesions (60%). Within the group with positive VCC, 14 were ALN (20%) and one a colorectal cancer. In the case-control analysis, 31 cases were to be analysed against the control group (n = 62). The presence of colonic polyps, adenomas, and ALN in patients with acromegaly was 19/31 (61.9%), 14/31 (45.16%), and 10/31 (32.25%), respectively, and in the control group, it was 18/62 (29.03%), 11/62 (17.74%), and 4/62 (6.45%), respectively. The risk of adenomas and ALN was higher in the acromegaly group compared to the control group: adenomas OR: 2.54 (95% CI 1.22-5.25) P=.005, ALN OR: 7.3 (2.4-25) P=.00. Conclusion: This preliminary case control study showed an increased risk of pre-cancerous colprectal lesions in patients with acromegaly, supporting the VCC screening at diagnosis.
