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

BACKGROUND: There has been increasing interest in the primary surgical treatment of patients with early T classification (T1-T2) oropharyngeal squamous cell carcinoma (OPSCC), with the stated goal of de-escalating or avoiding adjuvant treatment. Herein, the authors sought to determine the degree to which this interest has translated into changes in practice patterns, and the rates of adverse postoperative pathologic features. METHODS: Patients with T1 to T2 OPSCC in the National Cancer Data Base who were treated from 2004 through 2013 were categorized as receiving primary surgical or primary radiation-based treatment. Trends in treatment selection and factors related to the selection of primary surgery were examined. The rates of adverse pathologic features including positive surgical margins, extracapsular spread (ECS), and advanced T and N classifications after surgery were analyzed. RESULTS: Of 8768 patients with T1 to T2 OPSCC, 68% underwent primary surgical treatment, increasing from 56% in 2004 to 82% in 2013 (P<.0001). The highest versus lowest volume hospitals treated 78% versus 59% of patients with primary surgery (odds ratio, 2.23; 95% confidence interval, 1.55-3.22 [P<.0001]). Higher lymph node classification was found to be predictive of lower rates of primary surgery, but the majority of patients with clinical N2/N3 disease underwent primary surgery. Among patients treated with surgery, positive surgical margins were present in 24% and ECS in 25% of patients. The rate of positive surgical margins decreased over time (P<.0001) and was observed less often at high-volume centers (P<.0001). Among candidates for single-modality therapy (those with clinical T1-T2/N0-N1 disease), 33% had positive surgical margins and/or ECS and 47% had at least 1 adverse feature (T3-T4 disease, N2-N3 disease, positive surgical margins, and/or ECS). CONCLUSIONS: Primary surgical treatment among patients with early T classification OPSCC has become more widespread. © 2016 American Cancer Society. Source
