Proinflammatory diet is associated with increased risk of squamous cell head and neck cancer.

Diets high in fruits and vegetables and low in red meat intake have been associated with decreased risk of head and neck cancer. Additionally, chronic inflammation pathways and their association with cancer have been widely described. We hypothesized a proinflammatory diet, as measured by the dietary inflammatory index (DII® ), is associated with increased risk of head and neck cancer. We used the Carolina Head and Neck Cancer (CHANCE) study, a population-based case-control study of head and neck squamous cell carcinoma. Cases were recruited from a 46-county region in central North Carolina. Controls, frequency-matched on age, race, and sex were identified through the North Carolina Department of Motor Vehicle records. The DII score, adjusted for energy using the density approach (E-DII), was calculated from a food frequency questionnaire and split into four quartiles based on the distribution among controls. Adjusted odds ratios (ORs) were estimated with unconditional logistic regression. Cases had higher E-DII scores (i.e., a more proinflammatory diet) compared with controls (mean: -0.14 vs. -1.50; p value < 0.001). When compared with the lowest quartile, the OR for the highest quartile was 2.91 (95% confidence interval (CI): 2.16-3.95), followed by 1.93 (95% CI: 1.43-2.62) for the third quartile, and 1.37 (95% CI: 1.00-1.89) for the second quartile. Both alcohol and smoking had a significant additive interaction with E-DII (smoking relative excess risk due to interaction (RERI): 2.83; 95% CI: 1.36-4.30 and alcohol RERI: 1.75; 95% CI: 0.77-2.75). These results provide additional evidence for the association between proinflammatory diet and head and neck cancer.

QT-Interval Prolongation, Torsades de Pointes, and Heart Failure With EGFR Tyrosine Kinase Inhibitors in Non-Small Cell Lung Cancer: Systematic Review.

A systematic literature review was conducted to determine the incidence and mortality of QT-interval prolongation (QTp), torsades de pointes (TdP), and heart failure (HF) in patients with non-small cell lung cancer (NSCLC) who received epidermal growth factor receptor (EGFR) TKIs. Of 296 identified publications, 95 met eligibility criteria and were abstracted for QTp/TdP and HF outcomes (QTp/TdP: 83 publications, including 5 case study publications; HF: 79 publications, including 6 case study publications [involving 8 patients]). QTp incidence ranged from 0% to 27.8% in observational studies and from 0% to 11% in clinical trials, with no deaths due to QTp. There were no TdP events or deaths due to TdP. The incidence of HF ranged from 0% to 8%, and HF mortality rates ranged from 0% to 4%. Patients receiving treatment with EGFR TKIs should be monitored for signs of QTp, TdP, and HF per prescribing information. Standardized definitions and methods to improve monitoring of QTp, TdP, and HF-related events are needed in patients with NSCLC.

Geographic access to fertility counseling among adolescent and young adult women with cancer in North Carolina.

BACKGROUND: Fertility counseling is recommended for adolescent and young adult (AYA) women facing gonadotoxic cancer therapy. However, fertility care is subspecialized medical care offered at a limited number of institutions, making geographic access a potential barrier to guideline-concordant care. We assessed the relationship between geographic access and receipt of fertility counseling among AYA women with cancer. METHODS: Using data from the North Carolina Central Cancer Registry, we identified women diagnosed with lymphoma, gynecologic cancer, or breast cancer at ages 15-39 years during 2004-2015. Eligible women were invited to complete an online survey on various topics, including fertility counseling. Geographic access was measured, using geocoded addresses, as vehicular travel time from residence to the nearest fertility clinic available at diagnosis. Multivariable regression models were used to examine the association between travel time and receipt of fertility counseling by provider type: health care provider vs fertility specialist. RESULTS: Analyses included 380 women. Median travel time to a fertility clinic was 31 (IQR: 17-71) minutes. Overall, 75% received fertility counseling from a health care provider and 16% by a fertility specialist. Women who lived ≥30 minutes from a clinic were 13% less likely to receive fertility counseling by a health care provider (PR:0.87; 95% CI:0.75-1.00) and 49% less likely to receive counseling by a fertility specialist (PR:0.51; 95% CI:0.28-0.93). CONCLUSIONS: Women who lived further away from fertility clinics were less likely to receive fertility counseling. IMPACT: Interventions to improve access to fertility counseling should include strategies to alleviate the burden of geographic access.

Gastrostomy Tube Outcomes Among Surgical and Non-Surgical Services: A Retrospective Review.

BACKGROUND: Our objective was to evaluate differences in baseline characteristics, complications, and mortality among patients receiving a gastrostomy tube (GT) by surgical or non-surgical services. METHODS: We performed a retrospective analysis of adult patients who underwent GT placement from 2014 to 2017 at a single institution. Using bivariate and multivariable analyses, we compared baseline characteristics, complications, and overall 30-day mortality of patients undergoing GT placement with surgical or non-surgical services. RESULTS: Of the 1339 adults who underwent GT placement, surgical and non-surgical services performed 45% (n = 609) and 55% (n = 730) procedures, respectively. Gastrostomy tube-related complications were similar (29.6% surgical vs 28.8% non-surgical, P = .76). Thirty-day mortality was higher among non-surgical services (23.7% vs 16.5%, P = .004). On multivariable analysis, this was not significant (OR 1.21, 95% CI 0.83; 1.77). CONCLUSION: Surgical and non-surgical service placement of GTs had equivalent GT-related mortality and complication rates.

Disparities in fertility preservation use among adolescent and young adult women with cancer.

PURPOSE: Women face multiple barriers to fertility preservation after cancer diagnosis, but few studies have examined disparities in use of these services. METHODS: Women aged 15-39 years diagnosed with cancer during 2004-2015 were identified from the North Carolina Central Cancer Registry and linked to the Society for Assisted Reproductive Technology Clinic Outcomes Reporting System. Women who cryopreserved oocytes or embryos for fertility preservation (n = 96) were compared to women who received gonadotoxic treatment but did not use fertility preservation (n = 7964). Conditional logistic and log-binomial regression were used to estimate odds ratios (ORs) or prevalence ratios (PRs) and 95% confidence intervals (CIs). RESULTS: Few adolescent and young adult women with cancer in our study (1.2%) used fertility preservation. In multivariable regression, women less likely to use fertility preservation were older at diagnosis (ages 25-29 vs. 35-39: OR = 6.27, 95% CI: 3.35, 11.73); non-Hispanic Black (vs. non-Hispanic White: PR = 0.44, 95% CI: 0.24, 0.79); and parous at diagnosis (vs. nulliparous: PR = 0.24, 95% CI: 0.13, 0.45); or lived in census tracts that were non-urban (vs. urban: PR = 0.12, 95% CI: 0.04, 0.37) or of lower socioeconomic status (quintiles 1-3 vs. quintiles 4 and 5: PR = 0.39, 95% CI: 0.25, 0.61). CONCLUSIONS: Women with cancer who were older, non-Hispanic Black, parous, or living in areas that were non-urban or of lower socioeconomic position were less likely to use fertility preservation. IMPLICATIONS FOR CANCER SURVIVORS: Clinical and policy interventions are needed to ensure equitable access to fertility services among women facing cancer treatment-related infertility.

Evaluation of Complications and Weight Outcomes in Pediatric Cerebral Palsy Patients With Gastrostomy Tubes.

BACKGROUND: Feeding difficulties are common in children with cerebral palsy (CP). The goal of this study was to examine pediatric CP patients undergoing gastrostomy tube (G tube) placement and assess the association between patient characteristics and weight after 3 months, 6 months, and 1 year. METHODS: This was a retrospective study of all pediatric patients with CP who received a G tube placement between April 2014 and December 2017 at a single institution. Bivariate analysis was used to examine association between patient characteristics and the primary outcome of improvement in weight Z score at 3, 6, and 12 months. RESULTS: Of 63 patients who received a G tube, 81% had an increase in Z score at 3 months, 44% at 6 months, and 64% at 12 months. By 12 months, factors associated with a positive Z score change included moderate and severe malnutrition, lack of prior G tube, and fewer comorbidities. The majority (69.8%) of patients experienced complications. Seven (11%) patients died, with only 1 death related to G tube placement. DISCUSSION: The use of G tubes in CP patients resulted in an increase in an improvement in nutritional status for the majority of patients over the course of a year. Although most complications were minor, patients had a high complication rate and frequently visited the emergency department, highlighting the need for standardized education and follow-up among this patient population.

Complications and 3-month outcomes of children with hydrocephalus treated with ventriculoperitoneal shunts in Malawi.

OBJECTIVE: Hydrocephalus is the most common pediatric neurosurgical condition, with a high prevalence in low- and middle-income countries. Untreated, hydrocephalus leads to neurological disability or death. The epidemiology and outcomes of hydrocephalus treated by ventriculoperitoneal (VP) shunts in Sub-Saharan Africa are not well defined and vary by region. The aim of the present study was to examine the mortality and morbidity rates and predictors of mortality in children treated by VP shunt placement for hydrocephalus at Kamuzu Central Hospital in Lilongwe, Malawi. METHODS: This is a prospective study of 100 consecutive children presenting with hydrocephalus who were treated with VP shunt placement from January 2015 to August 2017. Demographics, nutritional status, maternal characteristics, developmental delay, shunt complications, readmissions, and in-hospital and 3-month mortality data were collected. Multivariate logistic regression was used to identify predictors of death within 3 months of surgery. RESULTS: Overall, 46% of participants were female, with an average age of 5.4 ± 3.7 months at the time of surgery. The majority of patients were term deliveries (87.8%) and were not malnourished (72.9%). Only 10.8% of children were diagnosed with meningitis before admission. In-hospital and 3-month mortality rates were 5.5% and 32.1%, respectively. The only significant association with mortality was maternal age, with older maternal age demonstrating decreased odds of 3-month mortality (OR 0.9, 95% CI 0.8-1.0, p = 0.045). CONCLUSIONS: Surgical management of hydrocephalus with VP shunts portends a high mortality rate in Malawi. The association of younger maternal age with mortality is likely a proxy for social determinants, which appear to contribute as much to mortality as patient factors. VP shunting is inadequate as a sole surgical management of hydrocephalus in resource-limited settings.

Prognostic significance of non-HPV16 genotypes in oropharyngeal squamous cell carcinoma.

OBJECTIVES: Recent studies have found that cases with oropharyngeal squamous cell carcinoma (OPSCC) positive for HPV16 genotype have better overall survival compared with cases positive for other HPV genotypes. We sought to further replicate these studies and determine if this relationship is modified by expression of p16 tumor suppressor protein. MATERIAL AND METHODS: We identified 238 OPSCC cases from the Carolina Head and Neck Cancer Study (CHANCE) study, a population based case-control study. Tumors that tested positive solely for HPV16 genotype and no other genotypes with PCR were classified as HPV16-positive. Tumors positive for any other high-risk HPV genotype were classified as non-HPV16-positive. Expression of p16 in the tumor was determined with immunohistochemistry. Follow-up time was calculated from the date of diagnosis to date of death or December 31, 2013. Overall survival was compared with the Kaplan-Meier curves and log-rank test. Hazard ratios (HR) adjusted for smoking, alcohol use, sex, race, and age was calculated with the Cox proportional hazard regression. RESULTS: Cases with HPV16-positive OPSCC had better overall survival than cases with non-HPV16-positive OPSCC (log-rank p-value: 0.010). When restricted to OPSCC cases positive for p16 expression, the same trend continued (log-rank p-value: 0.002). In the adjusted model, cases with non-HPV16-positive OPSCC had greater risk of death compared to cases with HPV16-positive tumors (HR: 1.92; 95% CI: 1.03, 3.60). CONCLUSIONS: This finding indicates that HPV genotyping carries valuable prognostic significance in addition to p16 status and future survival studies of OPSCC should take into account differing HPV genotypes.
