Objective To examine histologic findings and clinical outcomes of patients whounderwent neck dissection for residual neck masses. Methods From 1987 to 2008, 968 postchemotherapy retroperitoneal lymph node dissections (RPLND) were performed at our institution. We identified 41 of these patients who underwent a postchemotherapy residual neck mass resection. Results Thirty-nine patients presented with primary testis, one with retroperitoneal, and one with mediastinal GCT. Teratoma was present in 54% of patients at diagnosis. During the neck dissection, 23 (56.1%) patients had teratoma, 14 (34.2%) had fibrosis, three (7.3%) had viable GCT, and one had benign lymph nodes. There was histologic discordance between the neck and the RPLND in 22.5% of patients and between the neck and other extraretroperitoneal resection sites in 26.5% of patients. At a median follow-up of 49.5 months from diagnosis, 16 patients had recurrence, and seven had died of testis cancer. No patient had recurrence in the neck. Five of seven patients with residual viable cancer at extraretroperitoneal resection sites died of disease compared with two of 23 with teratoma and none with fibrosis (P = .0005). Conclusions Resection of residual postchemotherapy neck masses is indicated because of the high incidence of viable tumor or teratoma in the residual mass and the inability to accurately predict the histology of the neck masses. Resection of residual neck masses leads to excellent local control and can contribute to long-term disease control and survival. © 2011 Elsevier Inc. Source

Background: In this study by the International Collaborative Group, the authors examined a large cohort of patients accumulated from multiple institutions that had experience in craniofacial surgery with the objective of reporting outcomes and complications for craniofacial resection (CFR) in the elderly. Methods: One hundred seventy patients aged ≤ yen;70 years were included in the study. The median age was 75 years (range, 70-98 years). One hundred four patients (61%) had received previous single-modality or combined treatment, which included surgery in 79 patients (46%), radiation in 47 patients (28%), and chemotherapy in 13 patients (8%). The most common histology was squamous cell carcinoma (67 patients; 39%). The margins of resection were close or microscopically positive in 56 patients (33%). Sixty-eight patients received adjuvant radiotherapy (40%), and 3 patients received chemotherapy (2%). Complications were classified into overall, local, central nervous system (CNS), systemic, and orbital. Overall survival (OS), disease-specific survival (DSS), and recurrence-free survival (RFS) were determined by using the Kaplan-Meier method. Outcomes were compared with patients aged <70 years. Statistical analyses for outcomes were performed in relation to patient characteristics, tumor characteristics (including histology and extent of disease), surgical resection margins, previous radiation, and previous chemotherapy to determine predictive factors. Results: Postoperative mortality occurred in 16 patients (9%), and postoperative complications occurred in 72 patients (42%). Local wound complications occurred in 40 patients (24%), CNS complications occurred in 24 patients (14%), systemic complications occurred in 19 patients (11%), and orbital complications occurred in 4 patients (2%). Postoperative mortality and complications were significantly more frequent in elderly patients compared with patients aged <70 years (postoperative mortality: 9% vs 3%; P =.04; complications: 42% vs 32%; P =.0009). The 5-year OS, DSS, and RFS rates were significantly poorer than those for patients aged <70 years (OS: 42% vs 56%; P <.0001; DSS: 53% vs 61%; P =.04; RFS: 46% vs 54%; P =.03). Surgical margin status and primary tumor histology were independent predictors of OS, DSS, and RFS in multivariate analysis. Conclusions: CFR for malignant skull base tumors in elderly patients (aged ≤ yen;70 years) was associated with increased mortality, complications, and poorer outcomes compared with patients aged <70 years. © 2010 American Cancer Society.

Background:Lymph node density (LND) has previously been reported to reliably predict recurrence risk and survival in oral cavity squamous cell carcinoma (OSCC). This multicenter international study was designed to validate the concept of LND in OSCC.Methods:The study included 4254 patients diagnosed as having OSCC. The median follow-up was 41 months. Five-year overall survival (OS), disease-specific survival (DSS), disease-free survival (DFS), locoregional control and distant metastasis rates were calculated using the Kaplan-Meier method. Lymph node density (number of positive lymph nodes/total number of excised lymph nodes) was subjected to multivariate analysis.Results:The OS was 49% for patients with LND≤0.07 compared with 35% for patients with LND>0.07 (P<0.001). Similarly, the DSS was 60% for patients with LND≤0.07 compared with 41% for those with LND>0.07 (P<0.001). Lymph node density reliably stratified patients according to their risk of failure within the individual N subgroups (P=0.03). A modified TNM staging system based on LND ratio was consistently superior to the traditional system in estimating survival measures.Conclusion:This multi-institutional study validates the reliability and applicability of LND as a predictor of outcomes in OSCC. Lymph node density can potentially assist in identifying patients with poor outcomes and therefore for whom more aggressive adjuvant treatment is needed. © 2013 Cancer Research UK.

Introduction: There are no established guidelines for selecting patients for early tracheostomy. The aim was to determine the factors that could predict the possibility of intubation longer than 7 days in critically ill adult patients. Methods: This is cohort study made at a general intensive care unit. Patients who required at least 48 hours of mechanical ventilation were included. Data on the clinical and physiologic features were collected for every intubated patient on the third day. Uni- and multivariate statistical analyses were conducted to determine the variables associated with extubation. Results: 163 (62%) were male, and the median age was 59±17 years. Almost one-third (36%) of patients required mechanical ventilation longer than 7 days. The variables strongly associated with prolonged mechanical ventilation were: age (HR 0.97 (95% CI 0.96-0.99); diagnosis of surgical emergency in a patient with a medical condition (HR 3.68 (95% CI 1.62-8.35), diagnosis of surgical condition-non emergency (HR 8.17 (95% CI 2.12-31.3); diagnosis of non-surgical-medical condition (HR 5.26 (95% CI 1.85-14.9); APACHE II (HR 0.91 (95% CI 0.85-0.97) and SAPS II score (HR 1.04 (95% CI 1.00-1.09) The area under ROC curve used for prediction was 0.52. 16% of patients were extubated after day 8 of intubation. Conclusions: It was not possible to predict early extubation in critically ill adult patients with invasive mechanical ventilation with common clinical scales used at the ICU. However, the probability of successfully weaning patients from mechanical ventilation without a tracheostomy is low after the eighth day of intubation. Source

Granular cell tumours of the thyroid gland are rare, with only six previously reported cases in the English literature. Current histological, immunohistochemical and electron microscopic evidence favours a neural/Schwannian relationship. A case of a granular cell tumour of the thyroid gland in a healthy 36-year-old woman is described. The tumour was found incidentally following a right thyroid lobectomy for symptoms from an asymmetric multinodular goitre. Macroscopically, the lesion resembled a papillary microcarcinoma. Microscopically, the tumour was composed of nests of epithelioid cells with abundant granular, eosinophilic cytoplasm. The nests were divided by fibrous septa and peripherally interdigitated with surrounding thyroid follicles. Immunohistochemistry helped to distinguish the lesion from other neoplasms such as Hurthle cell tumour, medullary carcinoma or metastasis, and also from a histiocytic reaction to previous fine needle aspiration. On the basis of this diagnosis, no further intervention was required, and the patient was discharged following post-operative review. © 2011 Springer Science+Business Media, LLC. Source
