Outcomes of patients with oropharyngeal squamous cell carcinoma treated with induction chemotherapy followed by concurrent chemoradiation compared with those treated with concurrent chemoradiation.

BACKGROUND: Induction chemotherapy (IC) has been associated with a decreased risk of distant metastasis in locally advanced head and neck squamous cell carcinoma. However, its role in the treatment of oropharyngeal squamous cell carcinoma (OPSCC) is not well established. METHODS: The outcomes of patients with OPSCC treated with IC followed by concurrent chemoradiation (CRT) were compared with the outcomes of those treated with CRT alone. The primary outcome was overall survival (OS), and the secondary end points were the times to locoregional and distant recurrence. RESULTS: In an existing database, 585 patients met the inclusion criteria: 137 received IC plus CRT, and 448 received CRT. Most patients were positive for human papillomavirus (HPV; 90.9%). Patients receiving IC were more likely to present with a higher T stage, a higher N stage, and low neck disease. The 3-year OS rate was significantly lower in patients receiving IC (75.7%) versus CRT alone (92.9%). In a multicovariate analysis, receipt of IC (adjusted hazard ratio [aHR], 3.4; P < .001), HPV tumor status (aHR, 0.36; P = .002), and receipt of concurrent cetuximab (aHR, 2.7; P = .002) were independently associated with OS. The risk of distant metastasis was also significantly higher in IC patients (aHR, 2.8; P = .001), whereas an HPV-positive tumor status (aHR, 0.44; P = .032) and completion of therapy (aHR, 0.51; P = .034) were associated with a lower risk of distant metastasis. In HPV-positive patients, IC remained associated with distant metastatic progression (aHR, 2.6; P = .004) but not OS. CONCLUSIONS: In contrast to prior studies, IC was independently associated with worse OS and a higher risk of distant metastasis in patients with OPSCC. Future studies are needed to validate these findings.

Characterizing distant metastases and survival in oropharyngeal squamous cell carcinoma.

BACKGROUND: Outcomes of oropharyngeal squamous cell carcinoma (OPSCC) after development of distant metastases (DM) in the context of human papillomavirus (HPV) tumor status remain controversial in the literature. METHODS: OPSCC patients with DM treated between June 2015 and March 2019 were included from a prospectively enrolled database. Characteristics of DM including sites, episodes, and timing of disease were analyzed in addition to survival after DM. RESULTS: Sixty-nine HPV-positive and 18 HPV-negative OPSCC patients with DM were included. The 2-year survival after DM was higher for HPV-positive patients (54.0% vs. 11.3%, p < 0.001). HPV-positive patients did not demonstrate greater episodes or sites of DM. Multiple sites of DM, early development of DM, and Charlson comorbidity Index were independently associated with worse survival after DM. CONCLUSIONS: While multiple sites, early DM, and comorbidities were poor prognostic factors, OPSCC patients with distant progression can have substantial survival after DM, including M1 patients.

Social networks and condomless intercourse with female partners among male sex workers in the Dominican Republic.

Male sex workers (MSW) in the Dominican Republic (DR) have multiple sexual partners, including personal and client-relationships, and are disproportionately affected by human immunodeficiency virus (HIV). We examined the prevalence of condomless anal and/or vaginal intercourse (CI) among MSW in the DR as a function of social network factors. Self-report surveys and social network interviews were administered to MSW recruited through venue-based sampling (N = 220). A generalized linear model was used to complete a Poisson Regression model and identify variables significantly associated with the outcome of interest. CI was more common with female (28.3%) than with male partners (4.9%). Factors associated with CI with the last female partner included older age of MSW, CI with the last male partner, having a stable female partner (a consistent or main partner), and having ≥1 family member in the participants' social network. Partner and social network characteristics associated with CI among MSW suggest the utility of dyadic and network interventions to reduce HIV risk.

The digital divide in adoption and use of mobile health technology among caregivers of pediatric surgery patients.

PURPOSE: The purpose of this study was to identify mobile Health (mHealth) technology utilization among caregivers of pediatric surgery patients. METHODS: We provided a modified version of the 2012 mobile health survey from the Pew Research Center to English and Spanish-speaking caregivers of children aged <18years presenting to pediatric surgical outpatient clinics from June to July of 2016. RESULTS: A total of 171 caregivers completed the survey and included 57 (34%) whites, 30 (18%) blacks, 75 (44%) Hispanics, and 6 (4%) other races. Among these, 160 (94%) were smartphone owners. mHealth users were identified as individuals who used their phone to look up health information online, receive text updates from healthcare providers or pharmacists, or use any health-related smartphone applications. On univariate ordered logistic regression, race/ethnicity, primary language, education level, and income quartile were associated with level of mHealth technology use. The majority of responders (n=126, 76%) said that they would be very or moderately interested in trying a new smartphone app related to management of their child's health. CONCLUSION: While the majority of pediatric caregivers are smartphone owners, there are significant racial and socioeconomic differences in mHealth usage. Understanding these differences may be important in identifying barriers to adoption of mHealth technology. LEVEL OF EVIDENCE: Level IV case series with no comparison group.

Pediatric melanoma: incidence, treatment, and prognosis.

The purpose of this review is to outline recent advancements in diagnosis, treatment, and prevention of pediatric melanoma. Despite the recent decline in incidence, it continues to be the deadliest form of skin cancer in children and adolescents. Pediatric melanoma presents differently from adult melanoma; thus, the traditional asymmetry, border irregularity, color variegation, diameter >6 mm, and evolution (ABCDE) criteria have been modified to include features unique to pediatric melanoma (amelanotic, bleeding/bump, color uniformity, de novo/any diameter, evolution of mole). Surgical and medical management of pediatric melanoma continues to derive guidelines from adult melanoma treatment. However, more drug trials are being conducted to determine the specific impact of drug combinations on pediatric patients. Alongside medical and surgical treatment, prevention is a central component of battling the incidence, as ultraviolet (UV)-related mutations play a central role in the vast majority of pediatric melanoma cases. Aggressive prevention measures targeting sun safety and tanning bed usage have shown positive sun-safety behavior trends, as well as the potential to decrease melanomas that manifest later in life. As research into the field of pediatric melanoma continues to expand, a prevention paradigm needs to continue on a community-wide level.
