Dental Prosthetic Rehabilitation in Mandibular Reconstruction: Optimizing Timing and Patient Selection.

Background: Dental prosthetic rehabilitation (DPR) plays a critical role in restoring function and quality of life following mandibular reconstruction. This study examines the rate of patients undergoing dental implants and DPR after reconstruction of a segmental jaw defect with a fibula free flap reconstruction. We identify factors associated with successful dental implants and DPR in this patient population.

Trends in incidence, metastasis, and mortality from thyroid cancer in the USA from 1975 to 2019: a population-based study of age, period, and cohort effects.

Background: In the USA, the incidence of thyroid cancer increased rapidly for several decades, although some studies have suggested that it has now plateaued or even begun to decrease. We aimed to establish whether incidence in the USA has truly decreased or merely plateaued, and to understand some of the underlying factors driving these changes.

Methods: We conducted a retrospective, population-based study using the National Cancer Institute (NCI)'s Surveillance, Epidemiology, and End Results database and the National Center for Health Statistics database.

Use of the Superior Thyroid Artery as a Recipient Artery in Head and Neck Free Flap Reconstruction: Effects on Post-Operative Hypothyroidism.

Background: The superior thyroid artery (STA) as a recipient vessel in free flap reconstruction may theoretically impact thyroid function. This study aimed to assess whether the use of the STA has an adverse effect on thyroid function.

Methods: Retrospective review of 101 head and neck reconstructive cases.

Baseline weight recovery and mortality risk in head and neck cancer.

Background: As a surrogate of malnutrition, degree of weight loss and recovery from head and neck cancer (HNC) treatment is understudied. The influence of modifiable factors that affect weight, including speech/language pathology (SLP) and nutrition counseling, is also poorly defined. We characterize weight loss trends, baseline weight recovery (BWR), and the impact of interdisciplinary care on oncologic outcomes.

Patient perceptions underlying ctDNA molecular surveillance for HPV(+) oropharyngeal squamous cell carcinoma.

Objective: Circulating tumor DNA assays have robust potential as molecular surveillance tools. They may also exacerbate patient distress without improving outcomes. We investigate patient acceptability of a validated ctHPVDNA assay (NavDx) during cancer surveillance for HPV(+) oropharyngeal cancer (OPC).

Reciprocal inhibition between TP63 and STAT1 regulates anti-tumor immune response through interferon-γ signaling in squamous cancer.

Squamous cell carcinomas (SCCs) are common and aggressive malignancies. Immune check point blockade (ICB) therapy using PD-1/PD-L1 antibodies has been approved in several types of advanced SCCs. However, low response rate and treatment resistance are common.

Malpractice Trends Involving Active Surveillance Across Cancers.

Objective: To characterize malpractice trends related to active surveillance (AS) as a treatment strategy across cancers.

Background: Active surveillance is increasingly considered a viable management strategy for low-risk cancers. Since a subset of AS cases will progress, metastasize, or exhibit cancer-related mortality, a significant barrier to implementation is the perceived risk of litigation from missing the window for cure.

Surgical Management of Substernal Thyroid Goiters.

Substernal thyroid goiters can present with progressive symptoms involving compression of vital structures such as the esophagus, trachea, or large vessels. A multidisciplinary approach is critical when diagnosing and treating these patients. This article discusses patient presentation, workup, and management options for patients with substernal goiter as well as surgical pearls to minimize risk of complications.

Comprehensive analyses of partially methylated domains and differentially methylated regions in esophageal cancer reveal both cell-type- and cancer-specific epigenetic regulation.

Background: As one of the most common malignancies, esophageal cancer has two subtypes, squamous cell carcinoma and adenocarcinoma, arising from distinct cells-of-origin. Distinguishing cell-type-specific molecular features from cancer-specific characteristics is challenging.

Results: We analyze whole-genome bisulfite sequencing data on 45 esophageal tumor and nonmalignant samples from both subtypes.

Re-examining predictors of pathologic lymph node positivity in clinically node negative oral cavity cancer.

Background: Elective lymph node dissection (ELND) is performed for many early-stage oral cavity squamous cell carcinomas (OCSCC) with clinically negative necks (cN0), often guided by depth of invasion (DOI). However, DOI is less validated in non-tongue OC sites, and often correlates with other adverse features. We sought to evaluate the utility of DOI versus other factors for independently predicting pathologic lymph node positivity (pN+) in patients with cN0 OCSCC.

Comparative impact of grade on mortality across salivary cancers: A novel, unifying staging system.

Background: The comparative impact of histologic variants and grade has not been well described.

Methods: Salivary cancer histologies were profiled using hospital and population-based cancer registries. Multivariable models were employed to assess relationships between histology, grade, and survival.

Expanded Parameters in Active Surveillance for Low-risk Papillary Thyroid Carcinoma: A Nonrandomized Controlled Trial.

Importance: Unlike for prostate cancer, active surveillance for thyroid cancer has not achieved wide adoption. The parameters by which this approach is feasible are also not well defined, nor is the effect of patient anxiety.

Objective: To determine if expanded size/growth parameters for patients with low-risk thyroid cancer are viable, as well as to assess for cohort differences in anxiety.

Predicting Pathologic Lymph Node Positivity in cN0 Pharynx and Larynx Cancers.

Background: Elective neck dissection is a standard of care for pharynx and most larynx cancer patients undergoing surgery, based largely on historical series. It is unclear if this is necessary for all patients in the modern era.

Methods: Patients with cN0 oropharynx, larynx, and hypopharynx cancers diagnosed from 2010-2015 undergoing primary surgery were identified in the National Cancer Data Base.

Preoperative Identification of Medullary Thyroid Carcinoma (MTC): Clinical Validation of the Afirma MTC RNA-Sequencing Classifier.

Cytopathological evaluation of thyroid fine-needle aspiration biopsy (FNAB) specimens can fail to raise preoperative suspicion of medullary thyroid carcinoma (MTC). The Afirma RNA-sequencing MTC classifier identifies MTC among FNA samples that are cytologically indeterminate, suspicious, or malignant (Bethesda categories III-VI). In this study we report the development and clinical performance of this MTC classifier.

Nodal Metastasis Count and Oncologic Outcomes in Head and Neck Cancer: A Secondary Analysis of NRG/RTOG 9501, NRG/RTOG 0234, and EORTC 22931.

Purpose: A better understanding of the relationship between the spread of head and neck squamous cell carcinoma (HNSCC) to regional lymph nodes (LNs) and the frequency and manner of treatment failure should help design better treatment intensification strategies. In this study, we evaluated the relationship between recurrence patterns, mortality, and number of pathologically positive (+) LNs in HNSCC in 3 prospective randomized controlled trials.

Methods And Materials: We performed a secondary analysis of 947 patients with HNSCC enrolled in RTOG 9501 (n = 410), RTOG 0234 (n = 203), and EORTC 22931 (n = 334) undergoing surgery and postoperative radiation ± systemic therapy.

Quantitative Nodal Burden and Mortality Across Solid Cancers.

Background: Nodal staging systems vary substantially across solid tumors, implying heterogeneity in the behavior of nodal variables in various contexts. We hypothesized, in contradiction to this, that metastatic lymph node (LN) number is a universal and dominant predictor of outcome across solid tumors.

Methods: We performed a retrospective cohort analysis of 1 304 498 patients in the National Cancer Database undergoing surgery between 2004 and 2015 across 16 solid cancer sites.
