Less-than-subtotal parathyroidectomy increases the risk of persistent/recurrent hyperparathyroidism after parathyroidectomy in tertiary hyperparathyroidism after renal transplantation
The optimal surgical approach for tertiary hyperparathyroidism (HPT) after kidney transplantation is unknown. Existing studies are limited by small sample size, lack of adjustment for kidney function, and no long-term follow-up

Incidence and Risk Factors Associated with Readmission After Surgical Treatment for Adrenocortical Carcinoma
Background: Adrenocortical carcinoma (ACC) is a rare disease with a poor prognosis. Given the lack of data on readmission after resection of ACC, the objective of the current study was to define the incidence of readmission, as well as identify risk factors associated with readmission among patients with ACC who underwent surgical resection. Methods: Two hundred nine patients who underwent resection of ACC between January 1993 and December 2014 at 1 of 13 major centers in the USA were identified. Demographic and clinicopathological data were collected and analyzed relative to readmission. Results: Median patient age was 52 years, and 62 % of the patients were female. Median tumor size was 12 cm, and the majority of patients had an American Society of Anesthesiologists (ASA) class of 3–4 (n = 85, 56 %). The overall incidence of readmission within 90 days from surgery was 18 % (n = 38). Factors associated with readmission included high ASA class (odds ratio (OR), 4.88 (95 % confidence interval (CI), 1.75–13.61); P = 0.002), metastatic disease on presentation (OR, 2.98 (95 % CI, 1.37–6.46); P = 0.006), EBL (>700 mL: OR, 2.75 (95 % CI, 1.16–6.51); P = 0.02), complication (OR, 1.91 (95 % CI, 1.20–3.05); P = 0.007), and prolonged length of stay (LOS; ≥9 days: OR, 4.12 (95 % CI, 1.88–9.01); P < 0.001). On multivariate logistic regression, a high ASA class (OR, 4.01 (95 % CI, 1.44–11.17); P = 0.008) and metastatic disease on presentation (OR, 3.44 (95 % CI, 1.34–8.84); P = 0.01) remained independently associated with higher odds of readmission. Conclusion: Readmission following surgery for ACC was common as one in five patients experienced a readmission. Patients with a high ASA class and metastatic disease on presentation were over four and three times more likely to be readmitted after surgical treatment for ACC, respectively

Germline and somatic mutations in the tyrosine kinase domain of the MET proto-oncogene in papillary renal carcinomas
Hereditary papillary renal carcinoma (HPRC) is a recently recognized form of inherited kidney cancer characterized by a predisposition to develop multiple, bilateral papillary renal tumours. The pattern of inheritance of HPRC is consistent with autosomal dominant transmission with reduced penetrance. HPRC is histologically and genetically distinct from two other causes of inherited renal carcinoma, von Hippel-Lindau disease (VHL) and the chromosome translocation (3;8). Malignant papillary renal carcinomas are characterized by trisomy of chromosomes 7, 16 and 17, and in men, by loss of the Y chromosome. Inherited and sporadic clear cell renal carcinomas are characterized by inactivation of both copies of the VHL gene by mutation, and/or by hypermethylation. We found that the HPRC gene was located at chromosome 7q31.1-34 in a 27-centimorgan (cM) interval between D7S496 and D7S1837. We identified missense mutations located in the tyrosine kinase domain of the MET gene in the germline of affected members of HPRC families and in a subset of sporadic papillary renal carcinomas. Three mutations in the MET gene are located in codons that are homologous to those in c-kit and RET, proto-oncogenes that are targets of naturally-occurring mutations. The results suggest that missense mutations located in the MET proto-oncogene lead to constitutive activation of the MET protein and papillary renal carcinomas.link_to_subscribed_fulltex
Actual 10-year survivors following resection of adrenocortical carcinoma.
BackgroundAdrenocortical carcinoma (ACC) is a rare and aggressive malignancy with limited therapeutic options beyond surgical resection. The characteristics of actual long-term survivors following surgical resection for ACC have not been previously reported.MethodPatients who underwent resection for ACC at one of 13 academic institutions participating in the US Adrenocortical Carcinoma Group from 1993 to 2014 were analyzed. Patients were stratified into four groups: early mortality (died within 2 years), late mortality (died within 2-5 years), actual 5-year survivor (survived at least 5 years), and actual 10-year survivor (survived at least 10 years). Patients with less than 5 years of follow-up were excluded.ResultsAmong the 180 patients available for analysis, there were 49 actual 5-year survivors (27%) and 12 actual 10-year survivors (7%). Patients who experienced early mortality had higher rates of cortisol-secreting tumors, nodal metastasis, synchronous distant metastasis, and R1 or R2 resections (all P < 0.05). The need for multi-visceral resection, perioperative blood transfusion, and adjuvant therapy correlated with early mortality. However, nodal involvement, distant metastasis, and R1 resection did not preclude patients from becoming actual 10-year survivors. Ten of twelve actual 10-year survivors were women, and of the seven 10-year survivors who experienced disease recurrence, five had undergone repeat surgery to resect the recurrence.ConclusionSurgery for ACC can offer a 1 in 4 chance of actual 5-year survival and a 1 in 15 chance of actual 10-year survival. Long-term survival was often achieved with repeat resection for local or distant recurrence, further underscoring the important role of surgery in managing patients with ACC. J. Surg.

Outcomes after resection of cortisol-secreting adrenocortical carcinoma.
BackgroundWe sought to define the impact of cortisol-secreting status on outcomes after surgical resection of adrenocortical carcinoma (ACC).MethodsThe U.S ACC group database was queried to identify patients who underwent ACC resection between 1993 and 2014. The short-term and long-term outcomes were assessed.ResultsThe incidence of all functional and cortisol-secreting tumors was 40.6% and 22.6%, respectively. On multivariable analysis, cortisol secretion remained associated with an increased risk of postoperative complications (odds ratio = 2.25, 95 % confidence interval = 1.04 to 4.88; P = .04). At a median follow-up of 17.6 months, 118 patients (50.4%) had developed a recurrence. On multivariable analysis, after adjusting for patient and disease-related factors cortisol secretion independently predicted shorter recurrence-free survival (Hazard ratio = 2.05, 95% confidence interval = 1.16 to 3.60; P = .01).ConclusionsCortisol secretion was associated with an increased risk of postoperative morbidity. Recurrence remains high among patients with ACC after surgery; cortisol secretion was independently associated with a shorter recurrence-free survival. Tailoring postoperative surveillance of ACC patients based on their cortisol secreting status may be important
