RESUMO
INTRODUCTION: Treatment for melanoma after a positive sentinel lymph node biopsy includes nodal observation or lymphadenectomy. Important considerations for management, however, involve balancing the risk of recurrence and the risk of lymphedema after lymphadenectomy. METHODS: From the Merative MarketScan Research Databases, adult patients were queried from 2007 to 2021. International Classification of Disease, Ninth (ICD-9) and Tenth (ICD-10) Editions, diagnosis codes and Current Procedural Terminology codes were used to identify patients with melanoma diagnoses who underwent an index melanoma excision with a positive sentinel lymph node biopsy (SLNB). Main outcomes were completion lymph node dissection (CLND) utilization after a positive SLNB, developing lymphedema with or without CLND, and nodal basin recurrence 3 months or more after index excision. Subanalyses stratified by index excision year (2007-2017 and 2018-2021) and propensity score matched were additionally conducted. Demographics and comorbidities (measured by Elixhauser index) were recorded. RESULTS: A total of 153,085,453 patients were identified. Of those, 359,298 had a diagnosis of melanoma, and 202,456 patients underwent an excision procedure. The study cohort comprised 3717 patients with a melanoma diagnosis who underwent an excision procedure and had a positive SLNB. The mean age of the study cohort was 49 years, 57% were male, 41% were geographically located in the South, and 24% had an Elixhauser index of 4+. Among the 350 patients who did not undergo CLND, 10% experienced recurrence and 22% developed lymphedema. A total of 3367 patients underwent CLND, of which 8% experienced recurrence and 20% developed lymphedema. Completion lymph node dissection did not significantly affect risk of recurrence [odds ratio (OR), 1.370, P = 0.090] or lymphedema (OR, 1.114, P = 0.438). After stratification and propensity score matching, odds of experiencing lymphedema (OR, 1.604, P = 0.058) and recurrence (OR, 1.825, P = 0.058) after CLND were not significantly affected. Rates of CLND had significantly decreased (P < 0.001) overtime, without change in recurrence rate (P = 0.063). CONCLUSIONS: Electing for nodal observation does not increase the risk of recurrence or reduce risk of lymphedema. Just as CLND does not confer survival benefit, its decreased utilization has not increased recurrence rate.

INTRODUCTION: Autologous breast reconstruction (ABR) has increased in recent decades, although concerns for access remain. As such, our goal is to trend national demographics and operative characteristics of ABR in the United States. METHODS: Using the National Inpatient Sample, 2016-2019, the International Classification of Disease , Tenth Edition codes identified adult female encounters undergoing ABR. Demographics and procedure-related characteristics were recorded. Discharge weights generated national estimates. Statistical analysis included univariate testing and multivariate regression modeling. RESULTS: A total of 52,910 weighted encounters met the criteria (mean age, 51.5 ± 10.0 years). Autologous breast reconstruction utilization increased (Δ = +5%), 2016-2019, primarily driven by a rise in deep inferior epigastric perforator (DIEP) reconstructions (Δ = +28%; incidence rate ratio [IRR], 1.070; P < 0.001), which were predominant throughout the study period (69%). More recent surgery year, bilateral reconstruction, higher income levels, commercial insurance, and care in the South US region increased the odds of DIEP-based ABR ( P ≤ 0.036). Transverse rectus abdominis myocutaneous flaps, bilateral reconstructions, higher comorbidity levels, and experiencing complications increased the length of stay ( P ≤ 0.038). Most ABRs (75%) were privately insured. The rates of immediate reconstructions increased over the study period (from 26% to 46%; IRR, 1.223; P < 0.001), as did the rates of bilateral reconstructions (from 54% to 57%; IRR, 1.026; P = 0.030). The rates of ABRs performed at teaching hospitals remained high (90% to 93%; P = 0.242). CONCLUSIONS: As of 2019, ABR has become more prevalent, with the DIEP flap constituting the most common modality. With the increasing ABR popularity, efforts should be made to ensure geographic and financial accessibility.

INTRODUCTION: Few studies have analyzed epidemiologic factor associated with female patients presenting to the emergency department from facial fractures because of assault. Clearly understanding these factors may assist in developing effective strategies to decrease the incidence and sequelae of these injuries. OBJECTIVES: To determine the epidemiology of facial fractures because of assault in the female population. METHODS: All female facial fracture visits were queried in the 2019 Nationwide Emergency Department (ED) Sample database. The likelihood of a facial fracture encounter resulting from assault was modeled using logistic regression adjusting for demographics, insurance status, geographic region, location of patient residence, and income. Secondary outcomes analyzed hospitalization costs and adverse events. RESULTS: Of all facial fractures 12.4% of female encounters were due to assault were due to assault. Of assaulted females, 72.8% were between the ages of 20 and 40, and Black women experienced a disproportionate share of assault encounters (odds ratio [OR]=2.55; CI, 2.29-2.84). A large portion (46.4%) of encounters occurred in patients living in the lowest quartile of median household income, and 22.8% of patients were uninsured (OR=1.34; CI, 1.09-1.66). Assaulted patients were more likely to have fractures in nasal bone (58.1% vs. 42.5%), orbit (16.8% vs. 10.9%), zygoma (4.1% vs 3.6%), and mandible (8.7% vs. 4.8%) compared with their nonassaulted counterparts. CONCLUSIONS: Facial fractures were especially common in lower income, uninsured, urban, and Black populations. Examining the patterns of injury and presentation are critical to improve prevention strategies and screening tools, identifying critical patients, and develop a more efficient and effective system to treat and support female patients suffering facial fractures secondary to assault.

Orthognathic surgery typically relies on the rigid fixation of fracture fragments using metal hardware. Though hardware is usually intended to be implanted permanently, the removal of hardware (ROH) is sometimes indicated for a variety of reasons. The authors sought to identify risk factors for ROH following orthognathic surgery. The authors conducted a retrospective analysis of the Merative MarketScan Research Databases, 2007-2021 using Current Procedural Terminology (CPT) and International Classification of Disease (ICD-9 and ICD-10) codes to identify patients who underwent an index Le Fort 1 osteotomy and bilateral sagittal split osteotomy operation on the same day. Statistical analysis involved χ2, Shapiro-Wilk, Wilcoxon-Mann-Whitney, Poisson regression, and multivariable logistic regression tests. 4698 patients met the inclusion criteria. The mean age at surgery was 25 years, and 57% were female. ROH occurred in 5.9% of patients. The mean time to hardware removal was 190.5±172.4 days. In a multivariate logistic regression, increased odds of ROH were associated with older patient age [OR: 1.02 (1.01-1.03), P=0.046], sleep apnea [OR: 1.62 (1.13-2.32), P=0.018], and craniofacial syndrome and/or cleft diagnoses [OR: 1.88 (1.14-2.55), P<0.001]. In the same model, postoperative oral antibiotic prophylaxis was not associated with ROH (P=0.494). The incidence of all-cause complications [IRR: 1.03 (1.01-1.05), P<0.001] rose over the study period, while the incidence of ROH did not change significantly (P=0.281). Patients at elevated risk should be counseled on the increased possibility of a second operation for ROH before having orthognathic surgery to ensure expectations and health care utilization decisions align with the evidence.
RESUMO
Targeted grazing to control undesirable plant species is increasingly of interest across a diversity of ecosystems, particularly as an alternative or complement to widely used herbicides. However, there are limited comprehensive evaluations of targeted grazing that evaluate both invasive species management effectiveness and potential negative effects on the ecosystem. Phragmites australis, a tall-statured, dense perennial invasive grass from Eurasia, is a pervasive problem in wetlands across the North American continent. As with many invasive species where management has historically relied on herbicides and resistance is a growing concern, land managers seek viable alternatives that have minimal negative ecosystem impacts. Grazing has been used for millennia to manage native Phragmites in Europe. Similarly, in its invasive range within North America, small-scale studies suggest Phragmites may be suppressed by grazers. Yet, the effectiveness of grazing at large scales and its effects on broader ecosystem properties remain largely unknown. We evaluated the influence of targeted grazing on vegetation, soil nutrients, and water nutrients over two years in large plots (â¼300x the size of previous studies). We also tested the effects of mowing, a treatment that can be used to facilitate grazer access to large, dense Phragmites stands. In line with our predictions, we found that cattle grazing effectively suppressed invasive Phragmites over two years. Mowing reduced litter, and moderately reduced standing dead Phragmites, both of which suppress native plant germination in this system. However, these reductions in Phragmites were not accompanied by indications of native plant community recovery, as we had optimistically predicted. Despite the potential for grazing to reduce nutrient sequestration by plants and fertilize soils, we were surprised to find no clear negative effects of grazing on nutrient mobilization to groundwater or floodwater. Taken together, our findings indicate that targeted grazing, when implemented at broad scales over short time frames, is effective at achieving invasive plant management goals without sizable nutrient impacts. However, additional steps will be needed to achieve the restoration of diverse, robust native plant communities.

BACKGROUND: Development of evidence-based post-treatment surveillance guidelines in recurrent/metastatic head and neck squamous cell carcinoma (R/M HNSCC) is limited by comprehensive documentation of patterns of recurrence and metastatic spread. METHODS: A retrospective analysis of patients diagnosed with R/M HNSCC at a National Cancer Institute-designated cancer center between 1998- 2019 was performed (n = 447). Univariate and multivariate analysis identified patterns of recurrence and predictors of survival. RESULTS: Median overall survival (mOS) improved over time (6.7 months in 1998-2007 to 11.8 months in 2008-2019, p = .006). Predictors of worse mOS included human papillomavirus (HPV) negativity (hazard ratio [HR], 1.8; 95% confidence interval [CI], 1.2-2.6), high neutrophil/lymphocyte ratio (HR, 2.1 [1.4-3.0], disease-free interval (DFI) ≤6 months (HR, 1.4 [1.02-2.0]), and poor performance status (Eastern Cooperative Oncology Group, ≥2; HR, 1.91.1-3.4). In this cohort, 50.6% of recurrences occurred within 6 months of treatment completion, 72.5% occurred within 1 year, and 88.6% occurred within 2 years. Metachronous distant metastases were more likely to occur in patients with HPV-positive disease (odds ratio [OR], 2.3 [1.4-4.0]), DFI >6 months (OR, 2.4 [1.5-4.0]), and body mass index ≥30 (OR, 2.3 [1.1-4.8]). Oligometastatic disease treated with local ablative therapy was associated with improved survival over polymetastatic disease (HR, 0.36; 95% CI, 0.24-0.55). CONCLUSION: These data regarding patterns of distant metastasis in HNSCC support the clinical utility of early detection of recurrence. Patterns of recurrence in this population can be used to inform individualized surveillance programs as well as to risk-stratify eligible patients for clinical trials. PLAIN LANGUAGE SUMMARY: After treatment for head and neck cancer (HNC), patients are at risk of recurrence at prior sites of disease or at distant sites in the body. This study includes a large group of patients with recurrent or metastatic HNC and examines factors associated with survival outcomes and recurrence patterns. Patients with human papillomavirus (HPV)-positive HNC have good survival outcomes, but if they recur, this may be in distant regions of the body and may occur later than HPV-negative patients. These data argue for personalized follow-up schedules for patients with HNC, perhaps incorporating imaging studies or novel blood tests.

INTRODUCTION: Partial breast reconstruction with oncoplastic reduction can provide breast cancer patients with improved aesthetic outcomes after breast conservation therapy. This study evaluates the implications of simultaneous oncoplastic reduction with lumpectomy on complication rates, time to adjuvant radiation therapy, and rates of margin reexcision compared with lumpectomy alone. METHODS: The Clinformatics Data Mart Database is a national deidentified commercial claims data warehouse. From 2003 to 2020, adult female patients were queried to identify patients with a breast cancer diagnosis with International Classification of Disease codes. Among those, current procedural terminology codes were used to identify those who underwent lumpectomy alone versus lumpectomy with oncoplastic reduction. Patient demographics, complications, adjuvant oncologic therapies, and need for reexcision were recorded. Patients not continuously enrolled for at least 6 months before and after the index procedure were excluded. Multivariable regression and χ 2 tests were used for statistical analysis. RESULTS: Of 53,165 patients meeting criteria (mean age, 61.4 ± 11.6 years), 1552 (2.9%) underwent oncoplastic reduction. Diagnoses of most nonsurgical complications (seroma, wound dehiscence, postoperative infection, fat necrosis, tissue necrosis, and nonspecified complications of surgical care) were significantly higher in the oncoplastic reduction group, as were rates of some surgical complications (hematoma, seroma, and tissue debridement). However, undergoing oncoplastic reduction did not impact time to adjuvant radiation ( P = 0.194) and protected against positive margins requiring repeat lumpectomy or completion mastectomy ( P < 0.001). CONCLUSIONS: In patients undergoing breast conservation therapy, simultaneous oncoplastic reduction decreased occurrence of positive margins and did not impact time to adjuvant radiation therapy despite increased rates of surgical and nonsurgical complications.

INTRODUCTION: Optimal surveillance paradigms for survivors of early stage human papillomavirus (HPV)-related oropharyngeal cancer are not well defined. This study aimed to characterize patient interest in and factors associated with an altered surveillance paradigm. MATERIALS AND METHODS: We surveyed patients with Stage I or II HPV-related oropharyngeal cancer treated at a tertiary care institution from 2016 to 2019. Primary outcomes were descriptive assessment of patient knowledge, interest in altered surveillance, burdens of in-person appointments, and priorities for surveillance visits. Ordinal regression was used to identify correlates of interest in altered surveillance. RESULTS: Sixty-seven patients completed surveys from February to April 2020 at a median of 21 months since completing definitive treatment. A majority (61%) of patients were interested in a surveillance approach that decreased in-person clinic visits. Patients who self-identified as medical maximizers, had higher worry of cancer recurrence, or were in long-term relationships were less likely to be interested. Patients reported significant burdens associated with surveillance visits, including driving distance, time off work, and nonmedical costs. Patients were most concerned with discussing cancer recurrence (76%), physical quality of life (70%), mortality (61%), and mental quality of life (52%) with their providers at follow-up visits. CONCLUSION: Patients with early stage HPV-related oropharyngeal cancers are interested in altered surveillance approaches, experience significant burdens related to surveillance visits, and have concerns that are not well addressed with current surveillance approaches, including physical and mental quality of life. Optimized surveillance approaches should incorporate patient priorities and minimize associated burdens. IMPLICATIONS FOR PRACTICE: The number of patients with HPV-related oropharyngeal cancers is increasing, and numerous clinical trials are investigating novel approaches to treating these good-prognosis patients. There has been limited work assessing optimal surveillance paradigms in these patients. Patients experience significant appointment-related burdens and have concerns such as physical and mental quality of life. Additionally, patients with early stage HPV-related oropharyngeal cancers express interest in altered surveillance approaches that decrease in-person clinic visits. Optimization of surveillance paradigms to promote broader survivorship care in clinical practice is needed.

PURPOSE: Although many studies clearly demonstrate disparities in cancer clinical trial enrollment, there is a lack of consensus on potential causes. Furthermore, virtually nothing is known about associations between patients' decision-making style and their participation in clinical trials. METHODS: Women with newly diagnosed, stage 0-II breast cancer reported to the Georgia and Los Angeles County Surveillance, Epidemiology, and End Results (SEER) registries in 2013-2014 were surveyed approximately seven months after diagnosis. We investigated two primary outcome variables: (1) invitation to participate in a clinical trial, (2) participation in a clinical trial. We evaluated bivariate associations using Chi-squared tests and used multivariable logistic regression models to investigate associations between patient variables, including decision-making style, and the primary outcomes. RESULTS: 2578 patients responded (71% response rate); 30% were > age 65, 18% were black, 18% were Latina, 29% had ≤ high school education. 10% of patients reported invitation to participate in a clinical trial; 5% reported participation in a clinical trial. After adjustment younger age, receipt of chemotherapy or radiation, disease stage, and a more rational (versus more intuitive) decision-making style were associated with a higher odds of invitation to participate. Being married was associated with a higher odds of participation; having an annual family income ≥ $40,000 was associated with a lower odds of participation. CONCLUSIONS: 10% of patients reported invitation to participate in a clinical trial, and half of these reported participation. Invitation to participate varied by age and decision-making style, and participation varied by marital status and income.

Streams and rivers are important conduits of terrestrially derived carbon (C) to atmospheric and marine reservoirs. Leaf litter breakdown rates are expected to increase as water temperatures rise in response to climate change. The magnitude of increase in breakdown rates is uncertain, given differences in litter quality and microbial and detritivore community responses to temperature, factors that can influence the apparent temperature sensitivity of breakdown and the relative proportion of C lost to the atmosphere vs. stored or transported downstream. Here, we synthesized 1025 records of litter breakdown in streams and rivers to quantify its temperature sensitivity, as measured by the activation energy (Ea , in eV). Temperature sensitivity of litter breakdown varied among twelve plant genera for which Ea could be calculated. Higher values of Ea were correlated with lower-quality litter, but these correlations were influenced by a single, N-fixing genus (Alnus). Ea values converged when genera were classified into three breakdown rate categories, potentially due to continual water availability in streams and rivers modulating the influence of leaf chemistry on breakdown. Across all data representing 85 plant genera, the Ea was 0.34 ± 0.04 eV, or approximately half the value (0.65 eV) predicted by metabolic theory. Our results indicate that average breakdown rates may increase by 5-21% with a 1-4 °C rise in water temperature, rather than a 10-45% increase expected, according to metabolic theory. Differential warming of tropical and temperate biomes could result in a similar proportional increase in breakdown rates, despite variation in Ea values for these regions (0.75 ± 0.13 eV and 0.27 ± 0.05 eV, respectively). The relative proportions of gaseous C loss and organic matter transport downstream should not change with rising temperature given that Ea values for breakdown mediated by microbes alone and microbes plus detritivores were similar at the global scale.

PURPOSE OF REVIEW: Glioblastoma (GBM) is the most common and lethal primary brain tumor in adults, with a median survival of less than 2 years despite the standard of care treatment of 6 weeks of chemoradiotherapy. We review the data investigating hypofractionated radiotherapy (HFRT) in the treatment of newly diagnosed GBM. RECENT FINDINGS: Investigators have explored alternative radiotherapy strategies that shorten treatment duration with the goal of similar or improved survival while minimizing toxicity. HFRT over 1-3 weeks is already a standard of care for patients with advanced age or poor performance status. For young patients with good performance status, HFRT holds the promise of radiobiologically escalating the dose and potentially improving local control while maintaining quality of life. Through the use of shorter radiotherapy fractionation regimens coupled with novel systemic agents, improved outcomes for patients with GBM may be achieved.

Biota can be described in terms of elemental composition, expressed as an atomic ratio of carbon:nitrogen:phosphorus (refs 1-3). The elemental stoichiometry of microoorganisms is fundamental for understanding the production dynamics and biogeochemical cycles of ecosystems because microbial biomass is the trophic base of detrital food webs. Here we show that heterotrophic microbial communities of diverse composition from terrestrial soils and freshwater sediments share a common functional stoichiometry in relation to organic nutrient acquisition. The activities of four enzymes that catalyse the hydrolysis of assimilable products from the principal environmental sources of C, N and P show similar scaling relationships over several orders of magnitude, with a mean ratio for C:N:P activities near 1:1:1 in all habitats. We suggest that these ecoenzymatic ratios reflect the equilibria between the elemental composition of microbial biomass and detrital organic matter and the efficiencies of microbial nutrient assimilation and growth. Because ecoenzymatic activities intersect the stoichiometric and metabolic theories of ecology, they provide a functional measure of the threshold at which control of community metabolism shifts from nutrient to energy flow.

Radiation therapy after lymph node dissection increases the risk of developing painful and incurable lymphedema in breast cancer patients. Lymphedema occurs when lymphatic vessels become unable to maintain proper fluid balance. The sensitivity of lymphatic endothelial cells (LECs) to ionizing radiation has not been reported to date. Here, the radiosensitivity of LECs in vitro has been determined using clonogenic survival assays. The ability of various growth factors to alter LEC radiosensitivity was also examined. Vascular endothelial growth factor (VEGF)-C enhanced radiosensitivity when LECs were treated prior to radiation. VEGF-C-treated LECs exhibited higher levels of entry into the cell cycle at the time of radiation, with a greater number of cells in the S and G2/M phases. These LECs showed higher levels of γH2A.X-an indicator of DNA damage-after radiation. VEGF-C did not increase cell death as a result of radiation. Instead, it increased the relative number of quiescent LECs. These data suggest that abundant VEGF-C or lymphangiogenesis may predispose patients to radiation-induced lymphedema by impairing lymphatic vessel repair through induction of LEC quiescence.

INTRODUCTION: Burn injuries among the homeless are increasing as record numbers of people are unsheltered and resort to unsafe heating practices. This study characterizes burns in homeless encounters presenting to US emergency departments (EDs). METHODS: Burn encounters in the 2019 Nationwide Emergency Department Sample (NEDS) were queried. ICD-10 and CPT codes identified homelessness, injury regions, depths, total body surface area (TBSA %), and treatment plans. Demographics, comorbidities, and charges were analyzed. Discharge weights generated national estimates. Statistical analysis included univariate testing and multivariate modeling. RESULTS: Of 316,344 weighted ED visits meeting criteria, 1919 (0.6%) were homeless. Homeless encounters were older (mean age 44.83 vs. 32.39 years), male-predominant (71% vs. 52%), and had more comorbidities, and were more often White or Black race (p < 0.001). They more commonly presented to EDs in the West and were covered by Medicaid (51% vs. 33%) (p < 0.001). 12% and 5% of homeless burn injuries were related to self-harm and assault, respectively (p < 0.001). Homeless encounters experienced more third-degree burns (13% vs. 4%; p < 0.001), though TBSA % deciles were not significantly different (34% vs. 33% had TBSA % of ten or lower; p = 0.516). Homeless encounters were more often admitted (49% vs. 7%; p < 0.001), and homelessness increased odds of admission (OR 4.779; p < 0.001). Odds of transfer were significantly lower (OR 0.405; p = 0.021). CONCLUSION: Homeless burn ED encounters were more likely due to assault and self-inflicted injuries, and more severe. ED practitioners should be aware of these patients' unique presentation and triage to burn centers accordingly.

INTRODUCTION: SARS-CoV-2 (COVID-19) infection has been described as a cause of systemic hypercoagulability and a risk factor for the development of venous thromboembolism (VTE). Whereas some multispecialty studies have proposed a link between COVID-19 and postoperative thrombosis, other single-specialty studies have found no such association. We utilized a large national database to determine whether prior COVID-19 infection was associated with the incidence of VTE following common plastic surgery operations. METHODS: The Merative™ MarketScan® Research Databases were used to identify female patients who underwent index abdominal panniculectomy, breast reduction, autologous breast reconstruction, or implant-based breast reconstruction procedures between 2020 and 2021. International Classification of Disease, tenth edition (ICD-10) codes were used to identify patients diagnosed with COVID-19 preoperatively and those who experienced a VTE in the 90 days postoperatively. Propensity score matching and multivariable logistic regression were used to determine any independent association between COVID-19 and postoperative VTE. RESULTS: Twenty-four thousand two hundred and twenty-eight patients met inclusion criteria. Mean age at time of surgery was 44 years. Six percent carried a preoperative COVID-19 diagnosis, and postoperative VTE occurred in 1.3%. In a propensity-score-matched analysis of 2754 patients, COVID-19 did not significantly correlate with incidence of postoperative VTE (P = 0.463). Compared with a matched prepandemic cohort (14,151 patients), the incidence of VTE did not increase following any of the four studied procedures during the COVID-19 pandemic. CONCLUSION: This analysis of a national insurance claims database provides evidence against a link between resolved COVID-19 infection and VTE within 90 days of four common plastic surgery operations.

Background: As HIV-positive individuals utilizing highly active antiretroviral therapy live longer, the burden of breast cancer increases in the population. Breast reconstruction is an integral aspect of surgical treatment for many patients after a breast cancer diagnosis, prompting this examination of the characteristics and outcomes of breast reconstruction in this growing patient population. Methods: Using Merative MarketScan Research Databases, a large multipayer database, HIV-positive adult patients who underwent autologous or implant-based breast reconstruction between 2007 and 2021 were identified using International Classification of Disease codes and Common Procedural Terminology codes. In both HIV-positive and -negative cohorts, patient demographics, procedure-related complications, and postoperative revisions were recorded. Shapiro-Wilk, chi-square, Wilcoxon-Mann-Whitney, and multivariable logistic regression tests were used for statistical analysis. Results: Of 173,421 patients who underwent breast reconstruction, 1816 had an HIV diagnosis. HIV-positive patients were younger (P < 0.001), underwent surgery more recently (P < 0.001), more often underwent immediate breast reconstruction (P < 0.001), and had higher comorbidity levels (P < 0.001). There was a regional variation in which the patient cohorts underwent breast reconstruction. There was no significant difference in overall complication rates between patient groups, but HIV-negative patients more often underwent revision procedures (P = 0.009). Conclusions: When compared to their HIV-negative counterparts, breast reconstruction can be considered safe and efficacious in patients living with HIV. HIV-positive patients are a growing demographic who seek breast reconstruction, and surgeons must continue to further understand the unique implications of breast reconstruction in this population.
RESUMO
PURPOSE: Our purpose was to assess whether an association exists between surgical localization technique and lumpectomy cavity size on radiation therapy planning computed tomography (CT) scan. METHODS AND MATERIALS: A single-institution retrospective review was conducted of women undergoing breast conserving surgery with wire or magnetic seed guided lumpectomy followed by adjuvant radiation therapy from 2018 to 2021. Patients of a surgeon only performing 1 localization technique or undergoing bracketed localization were excluded. The primary outcome was lumpectomy cavity size on simulation CT. Confounding due to imbalance in patient and tumor factors was addressed with overlap weights derived from a propensity score analysis and used in a weighted multivariable analysis. Secondary outcomes included positive margins, total pathologic volume, boost delivery, and boost modality. RESULTS: Of 617 women who received lumpectomy during the study period, 387 were included in final analysis. Tumors of patients undergoing seed localization were more likely unifocal, assessable by ultrasound, and smaller. Seed use rates ranged from 27.7% to 70.7% per surgeon. There was no difference in positive margins (6.4 vs 5.4%, Pâ¯=â¯.79) or second surgeries (9.4 vs 8.1%, Pâ¯=â¯.79) between groups. Close margin rates were similar for ductal carcinoma in situ (Pâ¯=â¯.35) and invasive carcinoma (Pâ¯=â¯.97). In unadjusted bivariable analyses, wire localization was associated with larger total pathology volume (Pâ¯=â¯.004), but localization technique showed no association with CT cavity volume (Pâ¯=â¯.15). After adjusting for potentially confounding variables, multivariable analysis failed to show an association between localization technique and either CT cavity (Pâ¯=â¯.35) or total path volume (Pâ¯=â¯.08). There was no difference in indicated-boost delivery (Pâ¯=â¯.15) or electron boost (Pâ¯=â¯.14) by localization technique. CONCLUSIONS: There was no significant difference in CT cavity size by localization technique, suggesting choice between surgical techniques does not impede radiation therapy boost delivery.

BACKGROUND: Post-treatment surveillance recommendations for oropharyngeal cancer do not vary with p16 status despite the differences in outcomes. The optimal algorithm personalizing follow-up for these patients remains undefined. Here, we evaluate the feasibility and utility of incorporating electronic patient-reported outcomes (ePROs) and circulating tumor DNA (ctDNA) into routine surveillance for patients treated for p16+ oropharynx cancer. METHODS: A prospective registry was developed in which ePROs and ctDNA were incorporated into routine surveillance among patients with oropharynx cancer. ePROs were emailed monthly for 1 year and blood HPV ctDNA testing was performed every 3-6 months. The primary objective was to assess patient compliance with ePRO-based surveillance with adequate compliance defined as ≥85% of patients completing monthly ePROs. Sensitivity, specificity, and positive/negative predictive values to detect recurrence were calculated for ePROs, HPV ctDNA, or the combination. RESULTS: Of 122 patients who initially expressed interest, 76 completed the electronic consent process and 44/76 (58%) were compliant with monthly surveys over 1 year; thus adequate compliance was not achieved. Technical difficulties associated with ePRO receipt through email largely limited participation. Provider feedback was significantly associated with heightened ePRO compliance. One hundred and six patients had ctDNA testing with a mean number of three tests per patient. Sensitivity to detect recurrence was 75% for the combination of ePROs and ctDNA. CONCLUSION: Despite lower than anticipated compliance with ePROs, our findings show promise for incorporation of HPV ctDNA into surveillance paradigms for HPV-related oropharynx cancer with suggestions of methods to optimize ePRO formats for personalized surveillance.
RESUMO
PURPOSE: Locoregionally advanced HPV+ oropharyngeal squamous cell carcinoma (OPSCC) has excellent cure rates, although current treatment regimens are accompanied by acute and long-term toxicities. We designed a phase II deescalation trial for patients with HPV+ OPSCC to evaluate the feasibility of an upfront neck dissection to individualize definitive treatment selection to improve the quality of life without compromising survival. PATIENTS AND METHODS: Patients with T1-3, N0-2 HPV+ OPSCC underwent an upfront neck dissection with primary tumor biopsy. Arm A included patients with a single lymph node less than six centimeters, with no extracapsular spread (ECS) and no primary site adverse features underwent transoral surgery. Arm B included patients who had two or more positive lymph nodes with no ECS, or those with primary site adverse features were treated with radiation alone. Arm C included patients who had ECS in any lymph node and were treated with chemoradiation. The primary endpoint was quality of life at 1 year compared with a matched historical control. RESULTS: Thirty-four patients were enrolled and underwent selective neck dissection. On the basis of pathologic characteristics, 14 patients were assigned to arm A, 10 patients to arm B, and 9 to arm C. A significant improvement was observed in Head and Neck Quality of Life (HNQOL) compared with historical controls (-2.6 vs. -11.9, P = 0.034). With a median follow-up of 37 months, the 3-year overall survival was 100% and estimated 3-year estimated progression-free survival was 96% [95% confidence interval (CI), 76%-99%]. CONCLUSIONS: A neck dissection-driven treatment paradigm warrants further research as a deintensification strategy.
