RESUMO

OBJECTIVE: Tracheostomies are commonly performed in critically ill patients requiring prolonged mechanical ventilation. Although early tracheostomy has been associated with improved outcomes, the reasons for delayed tracheostomy are complex. We examined the impact of sociodemographic factors on tracheostomy timing and outcomes. METHODS: Medical records were retrospectively reviewed of ventilator-dependent adult patients who underwent tracheostomy from 2021 to 2022. Tracheostomy timing was defined as routine (<21 days) versus late (21 days or more). Sociodemographic variables were compared between cohorts using univariate and multivariate models. Secondary outcomes included hospital length of stay (LOS), decannulation, tracheostomy-related complications, and inhospital mortality. RESULTS: One hundred forty-two patients underwent tracheostomy after initial intubation: 74.7% routine (n = 106) and 25.4% late (n = 36). In a multivariate model adjusted for age, race, surgical service, tracheostomy technique, and time between consultation and surgery, non-English speaking patients and women were more likely to receive a late tracheostomy compared with English speaking patients and men, respectively (odds ratio [OR] 3.18, 95% confidence interval [CI] 1.03, 9.81, p < 0.05), (OR 3.15, 95% CI 1.18, 8.41, p < 0.05). Late tracheostomy was associated with longer median hospital LOS (62 vs. 52 days, p < 0.05). Tracheostomy timing did not significantly impact mortality, decannulation or tracheostomy-related complications. CONCLUSION: Despite an association between earlier tracheostomy and shorter LOS, non-English speaking patients and female patients are more likely to receive a late tracheostomy. Standardized protocols for tracheostomy timing may address bias in the referral and execution of tracheostomy and reduce unnecessary hospital days.

RESUMO

OBJECTIVE: Defining a clinician's ability to perceptually identify mass from voice will inform the feasibility, design priorities, and performance standards for tools developed to screen for laryngeal mass from voice. This study defined clinician ability of and examined the impact of expertise on screening for laryngeal mass from voice. STUDY DESIGN: Task comparison study between experts and nonexperts rating voices for the probability of a laryngeal mass. SETTING: Online, remote. METHODS: Experts (voice-focused speech-language pathologists and otolaryngologists) and nonexperts (general medicine providers) rated 5-s/i/voice samples (with pathology defined by laryngoscopy) for the probability of laryngeal mass via an online survey. The intraclass correlation coefficient (ICC) estimated interrater and intrarater reliability. Diagnostic performance metrics were calculated. A linear mixed effects model examined the impact of expertise and pathology on ratings. RESULTS: Forty clinicians (21 experts and 19 nonexperts) evaluated 344 voice samples. Experts outperformed nonexperts, with a higher area under the curve (70% vs 61%), sensitivity (49% vs 36%), and specificity (83% vs 77%) (all comparisons p < .05). Interrater reliability was fair for experts and poor for nonexperts (ICC: 0.48 vs 0.34), while intrarater reliability was excellent and good, respectively (ICC: 0.9 and 0.6). The main effects of expertise and underlying pathology were significant in the linear model (p < .001). CONCLUSION: Clinicians demonstrate inadequate performance screening for laryngeal mass from voice to use auditory perception for dysphonia triage. Experts' superior performance indicates that there is acoustic information in a voice that may be utilized to detect laryngeal mass based on voice.

RESUMO

OBJECTIVE: This study seeks to quantify how current speech recognition systems perform on dysphonic input and if they can be improved. STUDY DESIGN: Experimental machine learning methods based on a retrospective database. SETTING: Single academic voice center. METHODS: A database of dysphonic speech recordings was created and tested against 3 speech recognition platforms. Platform performance on dysphonic voice input was compared to platform performance on normal voice input. A custom speech recognition model was trained on voice from patients with spasmodic dysphonia or vocal cord paralysis. Custom model performance was compared to base model performance. RESULTS: All platforms performed well on normal voice, and 2 platforms performed significantly worse on dysphonic speech. Accuracy metrics on dysphonic speech returned values of 84.55%, 88.57%, and 93.56% for International Business Machines (IBM) Watson, Amazon Transcribe, and Microsoft Azure, respectively. The secondary analysis demonstrated that the lower performance of IBM Watson and Amazon Transcribe was driven by performance on spasmodic dysphonia and vocal fold paralysis. Thus, a custom model was built to increase the accuracy of these pathologies on the Microsoft platform. Overall, the performance of the custom model on dysphonic voices was 96.43% and on normal voices was 97.62%. CONCLUSION: Current speech recognition systems generally perform worse on dysphonic speech than on normal speech. We theorize that poor performance is a consequence of a lack of dysphonic voices in each platform's original training dataset. We address this limitation with transfer learning used to increase the performance of these systems on all dysphonic speech.

RESUMO

BACKGROUND: Recent studies have described the use of telehealth for pediatric surgical care during the COVID-19 pandemic. We aimed to evaluate equity in telehealth use by comparing rates of utilization and satisfaction with pediatric surgical telemedicine among Hispanic patients. METHODS: We conducted a retrospective cohort study of patients seen by a surgical subspecialty provider in the outpatient setting at a quaternary pediatric hospital between April 1 and June 30, 2020. Patients evaluated in the same three-month period in 2019 were analyzed as a historic control. Differences in Family Experience Survey (FES) responses based on race and ethnicity and preferred language of care were assessed using univariable and multivariable generalized linear modeling. RESULTS: The pandemic cohort included fewer patients of Hispanic ethnicity and fewer Spanish-speakers. After controlling for visit type, comparison of Spanish-speaking and English-speaking patients revealed that Spanish-speaking families had significantly lower scores for FES items that evaluated healthcare provider explaining (IRR 0.74, 95% CI: 0.61-0.90), listening (IRR 0.76, 95% CI: 0.63-0.92), and time spent with the family (IRR 0.73, 95% CI: 0.60-0.89). There were no differences in FES responses based on insurance status or degree of medical complexity. CONCLUSIONS: Telehealth services were less commonly used among Hispanic and Spanish-speaking patients. Language may differentially affect family satisfaction with healthcare and telehealth solutions. Strategies to mitigate these inequities are needed and may include strengthening interpreter services and providing language-concordant care. LEVEL OF EVIDENCE: Level IV.

RESUMO

INTRODUCTION: LatinX populations are rapidly growing in the USA, but still report lower levels of patient centered care and satisfaction when compared to their non-LatinX white counterparts. This review encompasses literature which describes patient experience instruments that (1) evaluate LatinX experience, (2) have validated Spanish versions, or (3) measure language-concordant care experiences. METHODS: A scoping review of literature in Ovid Medline, CINAHL, and PsycINFO was conducted. Articles were excluded if they were not applicable to the health care industry, did not include a patient experience instrument, or did not include LatinX or Spanish-speaking individuals within their study population. Data extraction was performed for concepts measured, study size, population, health care setting, and languages validated. RESULTS: This review identified 224 manuscripts. Of these, 81 met full inclusion criteria and represented 60 unique instruments. These covered six categories: general patient experience (43%, n = 26/60), experiences of discrimination/mistrust (12%, n = 7/60), cultural factors (10%, n = 6/60), patient-provider relationship (10%, n = 6/60), and communication (8%, n = 5/60). The remaining instruments measured multiple categories (17%, n = 10/60). Just over one third of instruments (n = 24, 5 pediatric, 19 adult) were validated in Spanish and an additional 14 (23%) were validated in English alone. Finally, 4 (7%) instruments were identified which were developed for use in a language concordant setting. CONCLUSION: Many instruments were identified which evaluate LatinX patient experience; however, none was both validated in Spanish and measured in all key categories of experience described above. Additionally, few instruments were developed for holistic evaluation of patient experience in pediatric or language concordant care settings.

RESUMO

Patients with head and neck cancer account for a large proportion of perioperative airway events. Further, these patients frequently require tracheostomy placement, which is one of the most common surgical procedures. This article reviews updated techniques in managing a difficult airway in patients with head and neck cancer, such as strategies for intubation/extubation, methods of tubeless laryngeal surgery, and techniques and relevant topics in tracheostomy management.

RESUMO

OBJECTIVES/HYPOTHESIS: To evaluate the clinical utility of postoperative contrast x-ray pharyngograms (XRP) for detecting pharyngoesophageal leaks following hypopharyngeal dysphagia surgery. STUDY DESIGN: Retrospective cohort study. METHODS: Medical records were reviewed of patients undergoing endoscopic (E-) or open (O-) Zenker's diverticulectomy (-ZD) with cricopharyngeal myotomy (-CPM) and CPM alone from 2008 to 2020 at one academic institution. Exclusion criteria were patients who were fed enterally or underwent repair of epiphrenic diverticula or O-CPM during laryngectomy. XRP clinical indication, impact on clinical care, and factors associated with use patterns were examined using descriptive statistics and logistic regression (LR). RESULTS: Of 152 subjects, 52% underwent O-ZD, 30% O-CPM, 15% E-ZD, and 3% E-CPM. An XRP was ordered for 65% of subjects, mostly routinely (94%). Among the four clinically apparent leaks observed in this cohort, early postoperative XRP confirmed one. It did not identify any clinically silent leaks. In univariate LR, undergoing XRP was associated with increasing day of diet advancement (odds ratio [OR] 4.7, 95% confidence interval [CI] 2.5-10.5) and hospital stay duration (OR 3.2, 95% CI 2.1-5.2), as well as surgeon specialty of otolaryngology compared to general surgery (OR 12.8, 95% CI 4.8-40.8) and procedure sub-type (O-CPM: OR 0.03, 95% CI 0.002-0.16). In multivariate LR, the following variables were significantly associated with XRP use: hospital stay (OR 1.7; 95% CI 1.1-3.0), otolaryngology (OR 105; 95% CI 15.4-2193), O-CPM (OR 0.03; 95% CI 0.002-0.16), and E-CPM (OR 0.04, 95% CI 0.002-0.60). CONCLUSIONS: Prospective, multi-institutional studies are needed to confirm the low clinical utility we observed of early, postoperative XRP following hypopharyngeal surgery for dysphagia.

RESUMO

OBJECTIVES/HYPOTHESIS: To characterize and identify predictors of 30-day adverse events in patients undergoing laryngeal framework surgery (LFS). STUDY DESIGN: This study is a retrospective analysis of the National Surgical Quality Improvement dataset. METHODS: LFS cases were identified from the American College of Surgeons-National Surgical Quality Improvement Program (ACS-NSQIP) database from 2008 to 2018. Demographic variables, patient comorbidities, and perioperative outcomes (any adverse event, 30-day readmission, 30-day reoperation, and unplanned intubation) were extracted. Patient-specific and surgery-specific factors associated with perioperative adverse events were examined using descriptive statistics and univariate logistic regression (LR). RESULTS: Of 283 patients who underwent LFS, 225 underwent laryngoplasty medialization, 56 underwent laryngoplasty medialization with arytenoidectomy or arytenoidopexy via an external approach, and 2 underwent local myocutaneous or fasciocutaneous advancement flap along with laryngoplasty. Medical comorbidities were present in 33.6% of patients and 57.9% were American Society of Anesthesiologists (ASA) Class III/IV (57.9%). LFS was performed as same-day surgery in 30.7% of cases. Fourteen patients (4.9%) suffered an adverse condition within 30 days following surgery. In univariate LR, ASA Class III or IV (odds ratio [OR] 4.6, 95% confidence interval [CI] 1.2-30.1) was the only predictor associated with any adverse event. Arytenoid adduction (AA) was associated with increased risk of reoperation within 30 days of the initial surgery (OR 6.4, 95% CI 1.0-49). CONCLUSIONS: LFS is a generally safe procedure with infrequent perioperative adverse events. In the ACS-NSQIP database, ASA classification of III or IV was associated with a higher risk for any 30-day adverse event and AA was associated with a higher risk for 30-day reoperation.

RESUMO

OBJECTIVES: In an era of increasing electronic health record (EHR) use monitoring and optimization, this study aims to quantify resident contributions and measure the effect of otolaryngology resident coverage in clinic on attending otolaryngologist EHR usage. METHODS: In one academic otolaryngology department, monthly attending provider efficiency profile metrics, data collected by the EHR vendor (Epic Systems Corporation) between January and June 2019 were accessed. Using weekly resident schedules, resident coverage of attending outpatient clinics was categorized by junior (post-graduate year [PGY] 1-3) and senior levels (PGY-4 through fellows) and correlated with attending EHR metrics using linear mixed effect models.Results: Thirteen attending otolaryngologists on average spent 58.8 minutes per day interacting with the EHR. In modeling, one day of trainee clinic coverage was associated with a 22 minutes reduction (95% CI [-37, -6]) in total daily attending EHR time and a 12 minutes reduction (95% CI [-21, -3]) in per day note time (P < .05). When stratifying by trainee level, senior coverage was associated with significantly reduced total daily time in EHR, per day time in clinical review, notes, and orders, as well as per appointment time in notes and clinical review (P < .05). Junior coverage was only associated with reduced per day note time (P < .05). CONCLUSIONS: Increasing resident clinic coverage was inversely related to attending time spent in the EHR and writing notes. Resident contributions to EHR workflows and hospital system productivity should continue to be studied and considered in EHR use measurement studies. LEVEL OF EVIDENCE: Level 4.

RESUMO

OBJECTIVES/HYPOTHESIS: Language barriers may impact family experience, which is a key measure of healthcare quality. We compared family satisfaction between Spanish-speaking families (SSF) and English-speaking families (ESF) in pediatric otolaryngology. STUDY DESIGN: Retrospective cohort study. METHODS: Responses from the Family Experience Survey (FES), a hospital quality benchmarking survey, were analyzed from 2017 to 2019 at one academic pediatric otolaryngology practice. Question responses were compared between SSF versus ESF using mixed effect logistic regression models, adjusting for patient age, medical complexity, and insurance. RESULTS: A total of 4,964 FES survey responses were included (14% SSF). In multivariate analysis adjusting for age, medical complexity, and insurance, SSF were 1.7 times more likely than ESF to rate their provider with the highest rating (i.e. 9-10/10; 95% confidence interval [CI] 1.24-2.22). However, SSF were less likely than ESF to provide the highest rating on many individual aspects of care, including whether providers explained things intelligibly (odds ratio [OR] 0.43, 95% CI 0.25-0.74), listened carefully (OR 0.36, 95% CI 0.28-0.47), knew their medical child's history (OR 0.53, 95% CI 0.44-0.64), provided understandable information (OR 0.36, 95% CI 0.16-0.83), spent sufficient time with them (OR 0.38, 95% CI 0.31-0.48), allowed them to discuss their questions (OR 0.57, 95% CI 0.47-0.70), or had enough input in their children's' care (OR 0.46, 95% CI 0.26-0.80). CONCLUSIONS: In a large cohort of pediatric otolaryngology patients, SSF rated many individual aspects of their child's care less positively compared to ESF, despite rating their provider highly. Further research is needed to explore the reasons for these differences and how they can be improved. LEVEL OF EVIDENCE: 4 Laryngoscope, 131:E2393-E2401, 2021.

RESUMO

BACKGROUND: Chronic invasive fungal sinusitis (CIFS) is a rare, life-threatening infection of the nose and sinuses. This study aims to identify factors that impact survival in 1 of the largest cohorts to date. METHODS: Pathology records were reviewed for biopsy-proven CIFS from 3 tertiary academic institutions from 1995 to 2016. Variables were analyzed using log-rank survival analysis. Univariate Cox regression was performed at 1 and 12 months. RESULTS: Thirty-eight patients were included. Hematologic malignancy and diabetes were the most common underlying diseases (32% each). Aspergillus was the most common fungus (63%). Greater than 75% of the patients had an absolute neutrophil count (ANC) >1000 at the time of diagnosis. Overall survival at 1, 6, and 12 months was 89%, 68%, and 48%, respectively. In univariate analysis, factors associated with worse survival included: ANC <500 at 12 months (hazard ratio [HR] 4.8; p = 0.01), ANC <1000 at 12 months (HR 5.8; p = 0.001), and recent chemotherapy (HR 4; p = 0.01). The following factor was associated with improved survival in univariate analysis: ANC as a linear variable in the entire cohort (HR 0.7; p = 0.005). CONCLUSION: We present a multi-institutional case-series of CIFS and long-term follow-up. ANC <1000 at time of diagnosis and recent chemotherapy (within 1 month of diagnosis) are associated with poorer survival, whereas a rising ANC >1000 is associated with improved survival at 12 months. Further prospective studies are needed to further define factors that affect outcomes.

RESUMO

This pilot study examines associations of perceived stigma pre-diagnosis with experienced stigma and social support post-diagnosis with qualitative data; and quantifies the interplay between pre- and post-diagnosis social factors on depressive symptoms among a sample of newly diagnosed Peruvian men who have sex with men (n = 67 total). Qualitative findings highlight the differences between perceptions of stigma pre-disclosure and actual social experiences post-disclosure for most participants. Perceived stigma pre-diagnosis was significantly related to post-diagnosis social support, B = -0.35, p = 0.03, and marginally associated with experienced stigma, B = 0.29, p = 0.07. Pre-diagnosis perceived stigma was associated with greater depressive symptoms, but only among individuals who reported higher amounts of social support, B = 0.55, p = 0.01. Findings suggest the importance of addressing social perceptions in order to optimize the beneficial effects of social support resources among newly diagnosed individuals.

RESUMO

BACKGROUND: The role of sublobar resection in the treatment of pulmonary typical carcinoids is controversial. This study aims to compare long-term outcomes between sublobar and lobar resections in patients with peripheral typical carcinoid. METHODS: We retrospectively compared consecutive patients who underwent curative sublobar resection with patients who underwent lobectomy for cT1-3 N0 M0 peripheral pulmonary typical carcinoid in eight centers between 2000 and 2015. Primary outcomes were rates and patterns of recurrence and overall survival. Cox regression modeling was performed to identify factors influencing overall survival and recurrence. Propensity score analysis was done, and overall survival was compared between the two groups. RESULTS: In all, 177 patients were analyzed, consisting of 74 sublobar resections and 103 lobectomies, with a total of 857 person-years of follow-up. The R1 resection rates were 7% and 1% after sublobar resection and lobectomy, respectively (P = .08). One of 5 patients with sublobar R1 resection had recurrence. Recurrence rate was 0.02 (95% confidence interval [CI]: 0.009 to 0.044) per person-year of follow-up after sublobar resection and 0.008 (95% CI: 0.003 to 0.02) after lobectomy (P = .15). Five-year survival rates were 91.7% (95% CI: 78.5% to 96.9%) and 97.4% (95% CI: 90.1% to 99.4%) after sublobar and lobar resection, respectively (P = .08). Extent of resection was not a predictor of recurrence or survival. Propensity score analysis confirmed a similar survival and freedom from recurrence between the two groups. CONCLUSIONS: Sublobar resection of peripheral cT1-3 N0 M0 pulmonary typical carcinoid was not associated with worse short- or long-term outcomes compared with lobectomy. In select patients, sublobar resection may be considered for treatment of peripheral typical carcinoids if an R0 resection is obtained.

RESUMO

A reduction in the global burden of malaria over the past two decades has encouraged efforts for regional malaria elimination. Despite the need to target all Plasmodium species, current focus is mainly directed towards Plasmodium falciparum, and to a lesser extent P. vivax. There is a substantial lack of data on both global and local transmission patterns of the neglected malaria parasites P. malariae and P. ovale spp. We used a species-specific real-time PCR assay targeting the Plasmodium 18s rRNA gene to evaluate temporal trends in the prevalence of all human malaria parasites over a 22-year period in a rural village in Tanzania.We tested 2897 blood samples collected in five cross-sectional surveys conducted between 1994 and 2016. Infections with P. falciparum, P. malariae, and P. ovale spp. were detected throughout the study period, while P. vivax was not detected. Between 1994 and 2010, we found a more than 90% reduction in the odds of infection with all detected species. The odds of P. falciparum infection was further reduced in 2016, while the odds of P. malariae and P. ovale spp. infection increased 2- and 6-fold, respectively, compared to 2010. In 2016, non-falciparum species occurred more often as mono-infections. The results demonstrate the persistent transmission of P. ovale spp., and to a lesser extent P. malariae despite a continued decline in P. falciparum transmission. This illustrates that the transmission patterns of the non-falciparum species do not necessarily follow those of P. falciparum, stressing the need for attention towards non-falciparum malaria in Africa. Malaria elimination will require a better understanding of the epidemiology of P. malariae and P. ovale spp. and improved tools for monitoring the transmission of all Plasmodium species, with a particular focus towards identifying asymptomatic carriers of infection and designing appropriate interventions to enhance malaria control.

RESUMO

BACKGROUND: Minimal knowledge exists regarding the outcome, prognosis and optimal treatment strategy for patients with pulmonary large cell neuroendocrine carcinomas (LCNEC) due to their rarity. We aimed to identify factors affecting survival and recurrence after resection to inform current treatment strategies. METHODS: We retrospectively reviewed 72 patients who had undergone a curative resection for LCNEC in 8 centers between 2000 and 2015. Univariable and multivariable analyses were performed to identify the factors influencing recurrence, disease-specific survival and overall survival. These included age, gender, previous malignancy, ECOG performance status, symptoms at diagnosis, extent of resection, extent of lymphadenectomy, additional chemo- and/or radiotherapy, tumor location, tumor size, pT, pleural invasion, pN and pStage. RESULTS: Median follow-up was 47 (95%CI 41-79) months; 5-year disease-specific and overall survival rates were 57.6% (95%CI 41.3-70.9) and 47.4% (95%CI 32.3-61.1). There were 22 systemic recurrences and 12 loco-regional recurrences. Tumor size was an independent prognostic factor for systemic recurrence [HR: 1.20 (95%CI 1.01-1.41); p = 0.03] with a threshold value of 3 cm (AUC = 0.71). For tumors ≤3 cm and >3 cm, 5-year freedom from systemic recurrence was 79.2% (95%CI 43.6-93.6) and 38.2% (95%CI 20.6-55.6) (p < 0.001) and 5-year disease-specific survival was 60.7% (95%CI 35.1-78.8) and 54.2% (95%CI 32.6-71.6) (p = 0.31), respectively. CONCLUSIONS: A large proportion of patients with surgically resected LCNEC will develop systemic recurrence after resection. Patients with tumors >3 cm have a significantly higher rate of systemic recurrence suggesting that adjuvant chemotherapy should be considered after complete resection of LCNEC >3 cm, even in the absence of nodal involvement.

RESUMO

A substantial body of literature has characterized how psychosocial factors, including HIV-related stigma and coping, are associated with HIV testing and HIV care utilization post-diagnosis. Less is known about if certain psychosocial characteristics pre-diagnosis may also predict linkage to care among individuals who receive an HIV-positive diagnosis. We examined if pre-diagnosis awareness/perception about HIV-related stigma and dispositional coping styles predicted linkage to HIV care within three months post-diagnosis with a secondary analysis of 604 patients from a randomized controlled trial (Sabes Study). Awareness/perception about HIV-related stigma, dispositional maladaptive and adaptive coping were measured before patients underwent an HIV test. Linkage to care was measured as receipt of care within three months of receiving the diagnosis. After adjusting for covariates, individuals who reported greater dispositional maladaptive coping pre-diagnosis had lower odds of linking to care, OR = 0.82, 95%CI [0.67, 1.00], p = .05. There was also a non-significant inverse association between dispositional adaptive coping pre-diagnosis and linkage to care. These preliminary data suggest the need for further longitudinal research and highlight the potential utility of pre-diagnosis psychosocial assessment and tailored counseling when providing positive HIV diagnosis results.

RESUMO

BACKGROUND: Acute invasive fungal sinusitis (AIFS) is a rare, aggressive infection occurring in immunocompromised patients. In this study we examined factors that affect survival in AIFS, and whether immune-stimulating therapies (IST) improve survival. METHODS: Pathology records of biopsy-proven AIFS were reviewed from 3 academic institutions from 1995 to 2016. Univariate and multivariate Cox regressions were performed at 1 and 3 months from diagnosis. RESULTS: One hundred fourteen patients were included; 45 received IST. In the univariate analysis, the following factors were associated with worse survival: hematologic malignancy (3-month hazard ratio [HR], 3.7; p = 0.01); recent chemotherapy (within 1 month of AIFS diagnosis) (3-month HR, 2.3; p = 0.02); recent bone marrow transplant (BMT) (3-month HR, 2.5; p = 0.02); and infection with atypical fungi (1-month HR, 3.1; p = 0.04). The following were associated with improved survival in univariate analysis: increasing A1c% (1-month HR, 0.7; p = 0.01) and surgical debridement (1-month HR, 0.1; p = 0.001). One third of patients with a hematologic malignancy had an absolute neutrophil count (ANC) >1000 at the time of diagnosis. ANC was not associated with prognosis in these patients. The following were associated with worse survival in multivariate analyses: hematologic malignancy; recent chemotherapy; atypical organisms; and cavernous sinus extension. In multivariate analyses, IST was associated with a 70% reduction in mortality at 1 month (p = 0.02). CONCLUSION: We presented the largest series of AIFS. Further studies are needed to examine the importance of ANC in diagnosis and prognosis. Patients diagnosed with atypical organisms may be at higher risk of death. IST likely improves short-term survival, but prospective studies are needed.

RESUMO

OBJECTIVE: Neuroendocrine tumors of the lung are currently staged with the 7th edition TNM non-small cell lung cancer staging system. This decision, based on data analysis without data on histology or disease-specific survival, makes its applicability limited. This study proposes a specific staging system for these tumors. METHODS: We retrospectively analyzed 510 consecutive patients (female/male, 313/197; median age, 61 years; interquartile range, 51-70) undergoing lung resection for a primary neuroendocrine tumor between 2000 and 2015 in 8 centers. Multivariable analysis was performed using a Cox proportional hazard model to identify factors associated with disease-specific survival. A new staging system was proposed on the basis of the results of this analysis. Kaplan-Meier disease-specific survival was analyzed by stage using the proposed and the 7th TNM staging system. RESULTS: Follow-up was completed in 490 of 510 patients at a median of 51 months (interquartile range, 18-99). Histology (G1-typical carcinoid vs G2-atypical carcinoid vs G3-large-cell neuroendocrine carcinoma) and pT were independently associated with survival, but pN was not. After regrouping histology and pT, we proposed the following staging system: IA (pT1-2G1), IB (pT3G1, pT1G2), IIA (pT4G1, pT2-3G2, pT1G3), IIB (pT4G2, pT2-3G3), and III (pT4G3). The 5-year survivals were 97.9%, 81.0%, 69.1%, 51.8%, and 0%, respectively. By using the 7th TNM, 5-year survivals were 95.0%, 92.3%, 67.7%, 70.9%, and 65.1% for stage IA, IB, IIA, IIB, and III, respectively. CONCLUSIONS: Incorporating histology and regrouping tumor stage create a unique neuroendocrine tumor staging system that seems to predict survival better than the 7th TNM classification.

RESUMO

BACKGROUND: This study aimed to assess the reliability and the validity of a prognostic model of survival recently developed by the European Society of Thoracic Surgery Neuroendocrine Tumor Working Group to predict 5-year overall survival after surgical resection of pulmonary typical carcinoid. METHODS: We retrospectively collected data on 240 consecutive patients (164 men, 76 women; median age, 58 years [interquartile range, 47 to 68]) who underwent curative lung resection for pulmonary typical carcinoid in seven centers between 2000 and 2015. For each patient, we calculated the corresponding risk class (A, B, C, D) using the following variables: male, age, previous malignancy, Eastern Cooperative Oncology Group performance status, peripheral tumor, TNM stage. Kaplan-Meier method, and Cox proportional hazards model were used for the statistical analysis. RESULTS: During a median follow-up of 42 months (interquartile range, 11 to 84), the 5-year overall survival was 94.2% (95% confidence interval [CI]: 90.2% to 98.2%); 15 of 240 patients died. A significantly decreasing rate of survival was observed from class A to class D (p = 0.004) with rates of 100% (95% CI: 100% to 100%), 96.3% (95% CI: 88.6% to 98.8%), 86.7% (95% CI: 63.0% to 95.7%), and 33.3% (95% CI: 0.9% to 77.4%), respectively, for class A, B, C, and D. This difference persisted also using clinical stage as a variable in the risk class calculation (p = 0.006). No differences were observed in term of overall survival among TNM stage I, II, and III patients (p = 0.94). CONCLUSIONS: This prognostic model of survival is easily applicable, it is validated by our independent cohort, and it appears to stratify better than the traditional TNM staging. Therefore, it may be useful in counseling patients about their outcomes from surgical treatment and in tailoring treatment for high-risk patients.

RESUMO

OBJECTIVES: The clinical utility of fluorodeoxyglucose-positron emission tomography (FDG-PET) and somatostatin receptor scintigraphy (SRS) in pulmonary carcinoids staging is unclear. This study aims to determine the role of FDG-PET and SRS in detecting hilar-mediastinal lymph node metastasis from these tumours. METHODS: We retrospectively collected the data of 380 patients who underwent lung resection for primary pulmonary carcinoid in seven centres between 2000 and 2015. Patients without nodal sampling ( n = 78) were excluded. In 302 patients [35% men, median age 58 (interquartile range 47-68) years] the results of preoperative computed tomography (CT) scan, FDG-PET and SRS were analysed and compared to the pathological findings after resection to determine the respective utility of these two nuclear tests. RESULTS: The sensitivity, specificity and negative predictive value in detecting N1 and N2 disease were respectively 33% and 46%, 93% and 90%, 88% and 95% for computed-tomography-scan, 38% and 60%, 93% and 95%, 88% and 95% for FDG-PET, 22% and 33%, 95% and 98%, 84% and 87% for SRS. The diagnostic accuracy for N1 and N2 disease of CT scan was not significantly different from that of FDG-PET ( P = 1.0 and P = 0.37 for N1 and N2 disease respectively) and of SRS ( P = 0.47 and P = 0.35 for N1 and N2 disease respectively). The sensitivity and specificity of these imaging tests were also similar when analysed by typical vs atypical histology. CONCLUSIONS: CT scan, FDG-PET and SRS showed similar performance in terms of nodal staging for pulmonary carcinoid. These findings suggest that additional nuclear imaging beyond CT scan is not required as long as a lymphadenectomy or nodal sampling is completed at resection.
