Objective: To analyze the penetrance and clinical course of isolated nonfunctioning tumors of the pancreas (NFTP) in MEN 1 patients, and to propose a strategy for managing them. Summary Background Data: Pancreaticoduodenal tumors develop in a majority of MEN 1 patients and are a major cause of death. The natural history of NFTP is poorly defined, and no clear-cut guidelines have been widely accepted regarding treatment. Methods: Data on 108 patients with isolated NFTP among 579 MEN 1 patients from the French Endocrine Tumor Study Group (GTE) were analyzed. Survival rates were calculated using the Kaplan-Meier method. Results: The penetrance of NFTP was 34% at age 50, making it the most frequent pancreaticoduodenal tumor in MEN 1 patients. Fortythree patients (40%) underwent surgery, 32 of them curatively. No patient died because of surgery. Average life expectancy for patients with NFTP was shorter than that for MEN 1 patients who did not have pancreaticoduodenal tumors. Thirteen patients died during follow-up, 10 due to NFTP. Tumor size was correlated with the risks of metastasis and death. These risks were low for patients with tumors Յ20 mm. Conclusions: NFTP are currently the most common tumors of the pancreaticoduodenal region in patients with MEN 1. Prevention of tumor spread by surgery should be balanced with potential operative mortality and morbidity. We do not recommend routine surgery for NFTP Յ20 mm. (Ann Surg 2006;243: 265-272) M ultiple endocrine neoplasia type 1 (MEN 1) is a rare autosomal dominant condition characterized by the development of endocrine parathyroid, pancreaticoduodenal, and pituitary tumors. In addition, MEN 1 patients are also prone to developing adrenal tumors, neuroendocrine tumors (in particular of the thymus or bronchus), dermal lesions, thyroid disease, and meningeal tumors. 1-7Pancreaticoduodenal tumors are often multiple, have been shown at autopsy to have developed in up to 80% of patients with MEN 1, and are a major cause of premature death in these patients. 8 -12 Most pancreaticoduodenal tumors are functioning tumors, the most frequent of which are gastrinomas and insulinomas, followed by the rare glucagonomas, VIPomas, GRFomas, and somatostatinomas. Surgical resection is the treatment of choice for functioning tumors of the pancreas, although controversy exists regarding the timing of surgery for gastrinomas. [13][14][15][16][17][18] In the absence of hormonal symptoms, nonfunctioning tumors of the pancreas (NFTP) have been recognized as a separate entity whose penetrance in the MEN 1 population is not well known. 19,20 In addition, because large surgical series of patients presenting with isolated NFTP are lacking and few clinical series have followed patients with NFTP, no clear-cut treatment guidelines have been widely accepted. Some authors have recommended a conservative approach for asymptomatic NFTP less than 1, 2, or 3 cm. [21][22][23][24] Others have recommended early surgical excision of all tumors as soon as they are found on imaging studies, or even ea...

In this randomized controlled trial, preoperative HIIT resulted in significant improvement in aerobic performances but failed to reduce early complications after lung cancer resection.

BackgroundHypoparathyroidism, the most common complication after thyroid surgery, leads to hypocalcaemia and significant medical problems. An RCT was undertaken to determine whether intraoperative parathyroid gland angiography with indocyanine green (ICG) could predict postoperative hypoparathyroidism, and obviate the need for systematic blood tests and oral calcium supplementation.MethodsBetween September 2014 and February 2016, patients who had at least one well perfused parathyroid gland on ICG angiography were randomized to receive standard follow‐up (measurement of calcium and parathyroid hormone (PTH) on postoperative day (POD) 1 and systematic supplementation with calcium and vitamin D; control group) or no supplementation and no blood test on POD 1 (intervention group). In all patients, calcium and PTH levels were measured 10–15 days after thyroidectomy. The primary endpoint was hypocalcaemia on POD 10–15.ResultsA total of 196 patients underwent ICG angiography during thyroid surgery, of whom 146 had at least one well perfused parathyroid gland on ICG angiography and were randomized. None of these patients presented with hypoparathyroidism, including those who did not receive calcium supplementation. The intervention group was statistically non‐inferior to the control group (exact 95 per cent c.i. of the difference in proportion of patients with hypocalcaemia –0·053 to 0·053; P = 0·012). Eleven of the 50 excluded patients, in whom no well perfused parathyroid gland could be identified by angiography, presented with hypoparathyroidism on POD 1, and six on POD 10–15, which was significantly different from the findings in randomized patients (P = 0·007).ConclusionICG angiography reliably predicts the vascularization of the parathyroid glands and obviates the need for postoperative measurement of calcium and PTH, and supplementation with calcium in patients with at least one well perfused parathyroid gland.

This study suggests that surgery may not be beneficial for MEN1 patients with NFPET < or = 2 cm.
