RESUMO

Autoinfarction of a parathyroid adenoma can have an atypical clinicoradiologic features that can mimic an inflammatory process or malignancy. In addition, the associated fibrosis makes surgical resection more challenging than for regular parathyroid adenomas. The implications of these findings are that while autoinfarction of parathyroid adenomas is a rare phenomenon, this entity should be considered when there are heterogeneous and cystic components on imaging in patients without hypercalcemia. Ultimately, histopathology is necessary for definitive diagnosis.

RESUMO

COVID-19 disrupted the ecology of schools and negatively influenced teacher mental health and retention. This mixed-methods study investigates the relationship between teacher well-being and teacher collegial relationships after a year enduring COVID-19 pandemic disruptions. By analyzing data collected through surveys (N = 185) and interviews (N = 27) with U.S. teachers in Spring-Summer 2021, we explore how teacher collegial relationships influenced teacher well-being and unpack how teachers collaborated and supported each other during the pandemic. We find that positive teacher-teacher and teacher-administrator relationships were significantly associated with greater teacher well-being and that teacher-teacher relationships deepened as colleagues engaged in innovative and supportive pedagogical problem solving and provided emotional support, a "silver lining" in education that arose during the pandemic. By sharing and affirming stories of how teachers organized, collaborated, engaged in professional sensemaking, and supported each other's emotional health and resilience, educational leaders can help reaffirm this narrative of teacher collective strength. Moving forward, schools should also create more opportunities for deep teacher collaboration, taking advantage of this opportunity to intentionally build on teachers' growing skills, trust, and capacity to address broad organizational and curricular innovation together.

RESUMO

Objectives: To quantify the current proportion of women in otolaryngology at different levels of professorship and determine whether these proportions differ by US region. Methods: Academic rank and gender at all ACGME-accredited otolaryngology programs in the United States were determined from departmental websites, Doximity, and LinkedIn from November 2021 to March 2022. Individuals were then further organized using US Census Bureau-designated regions. Results: Among the 2682 faculty positions at 124 ACGME-accredited programs, women held 706 (26.3%) of these positions. Female representation was highest at the assistant professorship level, with women holding 286 (37.2%) positions out of a total 769. At the associate professorship level, women held 141 (27.6%) of the 511 total positions. The largest gender disparity is seen at the full professorship level; only 69 (13.6%) positions out of 508 were held by women. Out of every region and rank, only assistant professorship in the West had no significant difference in percentages of men and women (p = .710). Female representation of professors in the Northeast was significantly lower than that of our reference group (the South; ß = -10.9, p = .020). Conclusions: Otolaryngology has exhibited great progress in increasing female representation, with assistant professorship in the West reaching gender parity. However, the gender gap at other faculty levels still leaves much to be desired, particularly in senior ranks. The lack of otolaryngologists at senior ranks is detrimental to mentorship of junior faculty, residents, and medical students. Renewed efforts should be made to decrease the gender disparity in the South, Northeast, and particularly at the professorship level.

RESUMO

Introduction: There is a lack of qualitative analysis of the personal experiences within Couples Matching. In this qualitative study, we aim to record personal attitudes, reflections, and advice on experiences with the Couples Match process. Methods: Our survey, consisting of two open-ended questions regarding the experience of Couples Matching, was distributed from January 2022 to March 2022 via email to 106 otolaryngology program directors across the nation. Survey responses were analyzed iteratively using the constructivist grounded theory to construct themes related to pre-match priorities, match-related stressors, and post-match satisfaction. Themes were developed inductively and refined iteratively as the dataset evolved. Results: 18 Couples Match residents responded. In response to the first question: "What was the most difficult part of the process for you and/or your partner?", we identified the following themes: cost and financial burden, increased stress on the relationship, sacrificing top choices, and finalizing the match list. In response to the second question: "Using your experience as a previous applicant, what advice would you give to another couple planning on couples matching?", we identified four common themes: compromise, advocacy, dynamic conversations, and applying broadly. Conclusion: We sought to understand the Couples Match process through the perspective of previous applicants. Analyzing the views and attitudes of Couples Match applicants, our study captures the most challenging aspects of the experience and highlights possible areas to improve advising for couples, including important factors to consider when applying, ranking, and interviewing.

RESUMO

OBJECTIVE: Oral leukoplakia is encountered frequently by otolaryngologists and oral and maxillofacial surgeons (OMFS). There are no consensus practice management guidelines for oral leukoplakia, resulting in heterogeneity in practice patterns. Characterization of practice patterns of providers who treat oral leukoplakia will be valuable to establish standards of care and future practice guidelines. MATERIAL AND METHODS: A survey was designed by the American Head and Neck Society Cancer Prevention Service collecting demographic and practice management data for treating oral leukoplakia. The survey was approved and distributed to members of the American Academy of Otolaryngology-Head and Neck Surgery and American Association of Oral and Maxillofacial Surgeons. Data analysis was performed using chi square and t-test where appropriate. RESULTS: 396 responses were collected: 83 OMFS, 81 head and neck fellowship-trained providers, and 232 otolaryngologists (non-head and neck fellowship-trained). Providers saw a wide volume of oral leukoplakia (23.0% >30 cases/year, 35.1% 11-30 cases/year, 41.2% 10 or less cases/year), with OMFS seeing more cases of oral leukoplakia. Factors most associated with consideration of initial biopsy included physical exam findings (94.4%), erythroplakia (82.3%), and smoking status (81.6%). The majority of respondents saw patients in follow-up within 1 month (24.8%) or within 1-3 months (46.5%). CONCLUSION: This survey identifies a range of practice patterns in initial management of oral leukoplakia, including indications for biopsy, and time for follow-up. This data provide insight into practice patterns amongst different groups of providers and can potentially lead to consensus guidelines for initial management of oral leukoplakia.

RESUMO

BACKGROUND: In TANGO, switching to dolutegravir/lamivudine (DTG/3TC) demonstrated long-term noninferior efficacy vs continuing tenofovir alafenamide-based regimens in treatment-experienced adults with HIV-1. The phase 3 SALSA study evaluated efficacy and safety of switching to DTG/3TC compared with continuing various 3-/4-drug current antiretroviral regimens (CARs). METHODS: Adults with HIV-1 RNA <50 copies/mL and no previous virologic failure were randomized (1:1, stratified by baseline third agent class) to switch to once-daily fixed-dose combination DTG/3TC or continue CAR (primary endpoint: proportion of participants with HIV-1 RNA ≥50 copies/mL at week 48; Snapshot, intention-to-treat-exposed population, 5% noninferiority margin). RESULTS: Overall, 493 adults (39% women; 39% aged ≥50 years; 19% African American/African heritage; 14% Asian) were randomized to switch to DTG/3TC (n = 246) or continue CAR (n = 247). At week 48, 1 (0.4%) participant in the DTG/3TC group and 3 (1.2%) in the CAR group had HIV-1 RNA ≥50 copies/mL (Snapshot), demonstrating noninferiority (adjusted difference, -0.8%; 95% CI, -2.4%, .8%). Zero participants met confirmed virologic withdrawal criteria; therefore, no resistance testing was performed. Drug-related adverse events were more frequent with DTG/3TC (20%) than CAR (6%) through week 48 but comparable post-week 24 (5% vs 2%, respectively). Proximal tubular renal function and bone turnover biomarkers improved with DTG/3TC. Both groups had generally minimal changes in lipids and inflammatory biomarkers. CONCLUSIONS: Switching to DTG/3TC was noninferior to continuing CAR for maintaining virologic suppression at week 48 with no observed resistance, supporting the efficacy, good safety, and high barrier to resistance of DTG/3TC.

RESUMO

Objectives Elective unilateral neck irradiation in well-lateralized tonsil carcinoma for N2b disease is controversial. Metrics regarding nodal burden beyond the N-stage to define the upper limit of this de-escalation approach remain limited. We investigated the role of nodal number, level, and volume on outcomes in patients with well-lateralized tonsil carcinoma treated with this approach. Methods A total of 37 patients received radiotherapy (RT) with unilateral neck coverage for well-lateralized tonsil cancer. Of patients, 95% had p16+ disease, and 81% were staged with positron emission tomography/computed tomography. The majority of patients received definitive chemoradiation on prospective de-escalation trials. Ten patients had ipsilateral neck dissections and were treated adjuvantly. The median RT dose to the ipsilateral neck (generally II-IV) was 45 Gy. The effects of nodal number, max dimension, volume, and level on recurrence-free survival (RFS) and overall survival (OS) were to be analyzed via Cox proportional hazards (Cox-PH). Results After a median follow-up of 3.9 years, two-year RFS and two-year OS were 100% and 97%, respectively. Given the 0% contralateral recurrence rate, Cox-PH analysis was not performed. Of patients, 70% were American Joint Committee on Cancer (AJCC) 7th edition N2b, with a median number of nodes, number of nodal levels, max dimension, and volume of two, one, 3.4 cm, and 15.6 cc, respectively. There were several patients with low-lying nodes; aggregate nodal volume measured was up to 85.4 cc. Conclusion Unilateral neck irradiation in well-lateralized tonsil carcinoma resulted in no contralateral recurrence. Nodal volume, level, and number do not seem to have a significant impact on outcomes.

RESUMO

BACKGROUND: Recurrent head and neck squamous cell carcinoma (HNSCC) is associated with poor overall survival (OS). Prior studies suggested incorporation of nab-paclitaxel (A) may improve outcomes in recurrent HNSCC. METHODS: This Phase I study evaluated induction with carboplatin and A followed by concomitant FHX (infusional 5-fluorouracil, hydroxyurea and twice-daily radiation therapy administered every other week) plus A with cohort dose escalation ranging from 10-100 mg/m2 in recurrent HNSCC. The primary endpoint was maximally tolerated dose (MTD) and dose-limiting toxicity (DLT) of A when given in combination with FHX (AFHX). RESULTS: Forty-eight eligible pts started induction; 28 pts started AFHX and were evaluable for toxicity. Two DLTs occurred (both Grade 4 mucositis) at a dose level 20 mg/m2. No further DLTs were observed with subsequent dose escalation. The MTD and recommended Phase II dose (RP2D) of A was 100 mg/m2. CONCLUSIONS: In this Phase I study, the RP2D of A with FHX is 100 mg/m2 (AFHX). The role of re-irradiation with immunotherapy warrants further investigation. CLINICAL TRIAL INFORMATION: This clinical trial was registered with ClinicalTrials.gov identifier: NCT01847326.

RESUMO

INTRODUCTION: Actinomycosis is a granulomatous infection that rarely involves the larynx or pharynx. Three cases of actinomycosis of the larynx or pharynx from our institution were reviewed and a systematic literature review was performed to better define surgical management, antibiotic therapy, risk factors, and incidence of recurrence or complications. MATERIALS AND METHODS: PubMed/Medline, Cochrane, Embase, and Google Scholar were searched on November 30, 2021 using the terms "laryngeal actinomycosis", "pharyngeal actinomycosis", "actinomycosis AND larynx", and "actinomycosis AND pharynx." Articles which did not describe appropriate sites or were non-English were excluded. Results were collected for demographic information, site(s) of infection, comorbidities, lesion characteristics and treatments. RESULTS: Along with three cases reported from our institution, 40 unique cases were reviewed from 37 studies for a total of 43 patients (Table 1). 34 (81.0 %) of the patients were male with the highest incidence of infection in the seventh decade (54.8 %). The most common site for the infection was the larynx (69.0 %) followed by the pharynx (16.7 %). Risk factors included a history of radiation therapy, immunosuppression, inhalational irritant, and diabetes (Table 3). The duration of antibiotic therapy varied greatly, from one month to one year and total follow up ranged from 1 month to 2.5 years (Table 1). CONCLUSIONS: A comprehensive review of the literature on pharyngolaryngeal actinomycosis shows that this infection has increased prevalence within the head and neck cancer patient population. Similar to cervicofacial actinomycosis, these atypical sites have shown favorable responses to extended antibiotic therapy and generally do not require aggressive surgical management.

RESUMO

INTRODUCTION: Granular cell tumors (GCT) are rare tumors that most frequently present in the oral cavity. While some present within the gastrointestinal tract, a GCT near the trachea is an extremely rare occurence. PRESENTATION OF CASE: A 42-year-old man presented to the Emergency Department after a motor vehicle accident. A computerized tomography (CT) scan revealed an incidental soft tissue 3.2 × 5.5 cm mass anterior to the esophagus and posterior to the trachea with no adjacent lymphadenopathy. The patient denied dyspnea, voice changes, or dysphagia. Due to its size and location, the patient underwent a transcervical excision of the retrotracheal tumor. Tumor cells were positive for CD68, CD163, S100, and SOX10, confirming a GCT. CONCLUSION: This is a distinctive presentation of a large (5 cm) GCT in the plane between the trachea and esophagus. GCTs are not often on the differential diagnosis of masses that present in this region.

RESUMO

BACKGROUND: Human papillomavirus (HPV)-associated oropharyngeal cancer (OPC) has a favorable prognosis which has led to efforts to de-intensify treatment. Response-adaptive de-escalated treatment is promising, however improved biomarkers are needed. Quantitative cell-free HPV-DNA (cfHPV-DNA) in plasma represents an attractive non-invasive biomarker for grading treatment response and post-treatment surveillance. This prospective study evaluates dynamic changes in cfHPV-DNA during induction therapy, definitive (chemo)radiotherapy, and post-treatment surveillance in the context of risk and response-adaptive treatment for HPV + OPC. METHODS: Patients with locoregional HPV + OPC are stratified into two cohorts: High risk (HR) (T4, N3, [Formula: see text] 20 pack-year smoking history (PYH), or non-HPV16 subtype); Low risk (LR) (all other patients). All patients receive induction chemotherapy with three cycles of carboplatin and paclitaxel. LR with ≥ 50% response receive treatment on the single-modality arm (minimally-invasive surgery or radiation alone to 50 Gy). HR with ≥ 50% response or LR with ≥ 30% and < 50% response receive treatment on the intermediate de-escalation arm (chemoradiation to 50 Gy with cisplatin). All other patients receive treatment on the regular dose arm with chemoradiation to 70 Gy with concurrent cisplatin. Plasma cfHPV-DNA is assessed during induction, (chemo)radiation, and post-treatment surveillance. The primary endpoint is correlation of quantitative cfHPV-DNA with radiographic response. DISCUSSION: A de-escalation treatment paradigm that reduces toxicity without compromising survival outcomes is urgently needed for HPV + OPC. Response to induction chemotherapy is predictive and prognostic and can select candidates for de-escalated definitive therapy. Assessment of quantitative cfHPV-DNA in the context of response-adaptive treatment of represents a promising reliable and convenient biomarker-driven strategy to guide personalized treatment in HPV + OPC. TRIAL REGISTRATION: This trial is registered with ClinicalTrials.gov on October 1st, 2020 with Identifier: NCT04572100 .

RESUMO

BACKGROUND: Favorable prognosis for Human papillomavirus-associated (HPV+) oropharyngeal cancer (OPC) led to investigation of response-adaptive de-escalation, yet long-term outcomes are unknown. We present expanded experience and follow-up of risk/response adaptive treatment de-intensification in HPV+ OPC. METHODS: A phase 2 trial (OPTIMA) and subsequent cohort of sequential off-protocol patients treated from September 2014 to November 2018 at the University of Chicago were reviewed. Eligible patients had T3-T4 or N2-3 (AJCC 7th edition) HPV+ OPC. Patients were stratified by risk: High-risk (HR) (T4, ≥N2c, or >10PYH), all others low-risk (LR). Induction chemotherapy (IC) included 3 cycles of carboplatin and nab-paclitaxel (OPTIMA) or paclitaxel (off-protocol). LR with ≥50% response received low-dose radiotherapy (RT) alone to 50 Gy (RT50). LR with 30-50% response and HR with ≥50% response received intermediate-dose chemoradiotherapy (CRT) to 45 Gy (CRT45). All others received full-dose CRT to 75 Gy (CRT75). RESULTS: 91 patients consented and 90 patients were treated, of which 31% had >10PYH, 34% had T3/4 disease, and 94% had N2b/N2c/N3 disease. 49% were LR and 51% were HR. Overall response rate to induction was 88%. De-escalated treatment was administered to 83%. Median follow-up was 4.2 years. Five-year OS, PFS, LRC, and DC were 90% (95% CI 81,95), 90% (95% CI 80,95), 96% (95% CI 90,99), and 96% (88,99) respectively. G-tube placement rates in RT50, CRT45, and CRT75 were 3%, 33%, and 80% respectively (p < 0.05). CONCLUSION: Risk/response adaptive de-escalated treatment for an inclusive cohort of HPV+ OPC demonstrates excellent survival with reduced toxicity with long-term follow-up.

RESUMO

OBJECTIVES: Research has associated both school night sleep duration (SNSD) and circadian preference (CP) with middle school-aged students' attendance and tardiness, but the interaction between these characteristics remains unexplored within this context, along with the impact of SNSD and CP on school suspension likelihood. Thus, this study investigated associations between SNSD, CP, and their interaction with middle school-aged student attendance, tardiness, and suspension, while accounting for sociodemographic characteristics. PARTICIPANTS: About 4175 students from 12 middle schools in the Madison, Wisconsin, Metropolitan School District. METHODS: Students completed a computer-based, sleep-related survey during class. Students reporting SNSD between 4 and 12 hours were included in the final analytical sample (N = 3860; mean age ± standard deviation = 12.0 ± 0.86 years; range = 10-16 years). CP was characterized using the single-item self-morningness/eveningness question. Linear mixed-effects regression estimated associations of SNSD and CP with tardiness and attendance. Logistic mixed-effects regression assessed associations with school suspension. Fully adjusted multilevel models included sociodemographic covariates, nesting students within schools. RESULTS: About 3860 student responses comprised the final sample, which had a SNSD of 8.15 ± 1.37 hours and general eveningness preference. Short-and-long SNSD associated with lower attendance and increased out-of-school suspension. Greater eveningness preference was negatively associated with attendance and tardiness. No SNSD and CP interactions emerged. Associations between sociodemographic characteristics and attendance, tardiness, and suspension were observed. CONCLUSIONS: Results support need for efforts to improve middle school-aged student sleep health and account for eveningness preference. Research clarifying the interactive influence of sleep, circadian, and sociodemographic characteristics on attendance and achievement is warranted.

RESUMO

Histologically benign airway strictures are frequently misdiagnosed as asthma or COPD and may present with severe symptoms including respiratory failure. A clear understanding of pathophysiology and existing classification systems is needed to determine the appropriate treatment options and predict clinical course. Clinically significant airway strictures can involve the upper and central airways extending from the subglottis to the lobar airways. Optimal evaluation includes a proper history and physical examination, neck and chest computed tomography, pulmonary function testing, endoscopy and serology. Available treatments include medical therapy, endoscopic procedures and open surgery which are based on the stricture's extent, location, etiology, morphology, severity of airway narrowing and patient's functional status. The acuity of the process, patient's co-morbidities and operability at the time of evaluation determine the need for open surgical or endoscopic interventions. The optimal management of patients with benign airway strictures requires the availability, expertise and collaboration of otolaryngologists, thoracic surgeons and interventional pulmonologists. Multidisciplinary airway teams can facilitate accurate diagnosis, guide management and avoid unnecessary procedures that could potentially worsen the extent of the disease or clinical course. Implementation of a complex airway program including multidisciplinary clinics and conferences ensures that such collaboration leads to timely, patient-centered and evidence-based interventions. In this article we outline algorithms of care and illustrate therapeutic techniques based on published evidence.

RESUMO

Noninvasive follicular thyroid neoplasms with papillary-like nuclear features (NIFTP) are follicular-patterned thyroid neoplasms defined by nuclear atypia and indolent behavior. They harbor RAS mutations, rather than BRAFV600E mutations as is observed in papillary thyroid carcinomas with extensive follicular growth. Reliably identifying NIFTPs aids in safe therapy de-escalation, but has proven to be challenging due to interobserver variability and morphologic heterogeneity. The genomic scoring system BRS (BRAF-RAS score) was developed to quantify the extent to which a tumor's expression profile resembles a BRAFV600E or RAS-mutant neoplasm. We proposed that deep learning prediction of BRS could differentiate NIFTP from other follicular-patterned neoplasms. A deep learning model was trained on slides from a dataset of 115 thyroid neoplasms to predict tumor subtype (NIFTP, PTC-EFG, or classic PTC), and was used to generate predictions for 497 thyroid neoplasms within The Cancer Genome Atlas (TCGA). Within follicular-patterned neoplasms, tumors with positive BRS (RAS-like) were 8.5 times as likely to carry an NIFTP prediction than tumors with negative BRS (89.7% vs 10.5%, P < 0.0001). To test the hypothesis that BRS may serve as a surrogate for biological processes that determine tumor subtype, a separate model was trained on TCGA slides to predict BRS as a linear outcome. This model performed well in cross-validation on the training set (R2 = 0.67, dichotomized AUC = 0.94). In our internal cohort, NIFTPs were near universally predicted to have RAS-like BRS; as a sole discriminator of NIFTP status, predicted BRS performed with an AUC of 0.99 globally and 0.97 when restricted to follicular-patterned neoplasms. BRAFV600E-mutant PTC-EFG had BRAFV600E-like predicted BRS (mean -0.49), nonmutant PTC-EFG had more intermediate predicted BRS (mean -0.17), and NIFTP had RAS-like BRS (mean 0.35; P < 0.0001). In summary, histologic features associated with the BRAF-RAS gene expression spectrum are detectable by deep learning and can aid in distinguishing indolent NIFTP from PTCs.

RESUMO

BACKGROUND AND AIM: Retrospective analysis of the utility of adjuvant radiation (RT) or chemoradiation (CRT) and identify prognostic features for patients with high-risk head and neck salivary gland cancers. METHODS: From 1/1997 to 12/2017, 108 patients underwent surgery, and RT (n = 50) or CRT (n = 58) for positive lymph node(s), extracapsular extension, perineural invasion, lymphovascular space invasion, positive/close margin, and/or grade 3 disease. Outcomes were estimated with the Kaplan-Meier method. Significant predictors identified through regression analyses were incorporated into multivariable regression (MVA). Toxicities were compared using chi-square. RESULTS: The median follow-up was 52 months (range: 3-226). The number of risk factors (RFs) between RT and CRT groups were: 0 to 1 (44% vs 7%), 2 to 3 (48% vs 41%), or 4 to 6 (8% vs 52%), respectively (P < .01). On MVA, stage 3 or 4 disease predicted worse outcomes including overall survival (HR 4.55, P = .01). Increasing number of RFs predicted worse disease-free survival, distant metastasis-free survival, and overall survival (2-3 RFs: HR 3.38, P = .03; 4-6 RFs: HR 5.78, P < .01), but not locoregional control (P = .54). So, adjuvant CRT may have provided comparable locoregional control for patients with more adverse features, but the CRT did not translate into improved distant control. There was no difference in acute or late grade 3+ toxicities, or parenteral nutrition (P = .98, P = .85, and P = .83), respectively. CONCLUSIONS: Adjuvant CRT provides adequate locoregional control in patients with more adverse RFs. The absolute number of RFs serves prognostic significance and should be considered in future prospective trials.

RESUMO

PURPOSE: To report functional outcomes for patients with human papillomavirus-positive oropharyngeal cancer treated on a phase 2 protocol of risk- and induction chemotherapy response-adapted dose and volume de-escalated radiation therapy (RT)/chemoradiation (CRT). METHODS AND MATERIALS: Patients were stratified as low risk (LR) or high risk (HR) according to T/N-stage and smoking history. Induction chemotherapy was followed by radiographic response assessment. LR patients with ≥50% response received 50 Gy RT (RT50), whereas LR patients with 30% to 50% response or HR patients with ≥50% response received 45 Gy CRT (CRT45). All other patients received 75 Gy CRT (CRT75) with RT limited to the first echelon of uninvolved nodes. Pre- and post-RT/CRT modified barium swallow studies were performed. Percutaneous endoscopic gastrostomy (PEG) tube placement, body mass index (BMI), and narcotic use were recorded. Statistical comparisons used linear or logistic regression, the Mann-Whitney U test, the χ2 test, or Fisher's exact test as appropriate. RESULTS: Twenty-eight LR and 34 HR patients were enrolled; 49 completed RT50/CRT45 and 11 completed CRT75. PEG-tube dependency at the end of RT/CRT and 3 months post-RT/CRT significantly differed according to risk and treatment groups (all P < .05). Treatment intensity was independently associated with 3-month PEG status while adjusting for risk group (P = .002). The CRT75 group had a median -8.42% change from baseline BMI at 1 year post-RT/CRT versus -2.54% for the RT50/CRT45 group (P = .01). At the end of RT/CRT, CRT75 patients were less likely to tolerate a normal diet, more likely to have swallowing performance status scale scores ≥4, more likely to have Rosenbek's penetration-aspiration scores ≥7, more likely to have developed trismus, and more likely to require narcotics >2 months (all P < .05). CONCLUSIONS: Induction chemotherapy followed by risk- and response-adapted dose and volume de-escalated RT/CRT is associated with clinically meaningful functional outcomes including (1) improved swallowing function, (2) higher BMI, and (3) shorter narcotic use for patients receiving de-escalation.

RESUMO

BACKGROUND: Primary analyses of the SWORD-1 and SWORD-2 trials at 48 weeks showed that switching to a two-drug regimen of dolutegravir plus rilpivirine was non-inferior to continuing a standard three-drug or four-drug antiretroviral regimen for maintenance of virological suppression in people with HIV-1. Here, we present efficacy and safety data from the 100-week analysis of the trials. METHODS: SWORD-1 and SWORD-2 are identically designed, randomised, open-label phase 3 studies at 65 centres in 13 countries and 60 centres in 11 countries, respectively. Adults aged 18 years or older who were on a standard three-drug or four-drug antiretroviral therapy (ART) and had had fewer than 50 HIV-1 RNA copies per mL of plasma for at least 6 months were randomly assigned (1:1) to 50 mg dolutegravir plus 25 mg rilpivirine orally once daily (early-switch group) or to continue their standard regimen for 52 weeks before switching to the dolutegravir plus rilpivirine combination (ie, the late-switch group). In this analysis of week 100 data, the efficacy endpoint of interest was the proportion of participants with fewer than 50 copies of HIV-1 RNA per mL of plasma (per the US Food and Drug Administration snapshot algorithm). This outcome was assessed in all randomly assigned participants who received at least one dose of the study drug. Data were analysed after the last participant completed week 100 (Sept 15, 2017) and verified through the data cutoff (Nov 21, 2017). SWORD-1 and SWORD-2 are registered with ClinicalTrials.gov, numbers NCT02429791 and NCT02422797, respectively. FINDINGS: 513 participants were randomly assigned to dolutegravir plus rilpivirine (ie, the early-switch group) and 511 to continue their standard ART regimen, 477 of whom then switched to dolutegravir plus rilpivirine at week 52 (ie, the late-switch group). At week 100, 456 (89% [95% CI 86-92]) of 513 participants in the early-switch group and 444 (93% [91-95]) of 477 in the late-switch group had fewer than 50 HIV-1 RNA copies per mL. Drug-related adverse events occurred in 103 (20%) participants in the early-switch group and 58 (12%) in the late-switch group. The most common drug-related adverse events were headache (11 participants in the early-switch group [2%] vs eight [2%] in the late-switch group) and nausea (eight [2%] vs five [1%]). INTERPRETATION: The combination of dolutegravir plus rilpivirine sustained virological suppression of HIV-1, was associated with a low frequency of virological failure, and had a favourable safety profile, which support its use as a nucleoside reverse transcriptase inhibitor-sparing and protease inhibitor-sparing alternative to three-drug regimens that reduces overall exposure to ART.

RESUMO

Mucoepidermoid carcinoma (MEC) is the most common salivary gland malignancy, but categorization is complicated by variability in grading systems and uncertain prognostic significance of MAML2 rearrangement. The aims of this study were to determine the prognostic significance of MEC grading systems and MAML2 rearrangement status. Fifty-three carcinomas originally diagnosed as MEC (45 primary; 8 recurrent) of major and minor salivary glands were graded according to modified Healey, Brandwein, AFIP, and Katabi systems. Fluorescence in situ hybridization for MAML2 rearrangement was performed. Clinical features and outcomes were recorded. Twenty-five (47%) carcinomas scored the same in all grading systems. The most common histologic feature leading to a diagnosis of intermediate grade was isolated solid growth. Brandwein assigned the highest percentage of high grade (29%) and AFIP the highest percentage of low grade (80%). MAML2 was rearranged in 37/46 (80%) cases. Forty-three (81%) were morphologically compatible with MEC, and these were more likely to be low-intermediate grade and MAML2-rearranged. Of primary carcinomas, 6 (13%) recurred. Statistically significant univariate risk factors for recurrence included non-MEC morphology, stage T4, and high Brandwein grade. Margin status, MAML2 rearrangement, and isolated solid growth were not predictive of recurrence. A binary grading system (Brandwein high vs. low-plus-intermediate) could be considered to better reflect biological behavior in MEC. Our study confirms that MAML2 wildtype tumors more likely represent high grade non-MECs, and prior studies demonstrating worse prognosis in MAML2-nonrearranged MECs may be diluted by high-grade non-MECs.
