This study examined the effect of short-term changes in ambient temperature on hospital admissions among children aged less than 5 years old in Hanoi, Vietnam. Data on daily hospital admissions from January 2010 to June 2014 were collected from two hospitals. Daily meteorological data were obtained for the same period. We applied time series analysis to evaluate the risk of hospitalisation related to hot and cold weather by age and causes. We found that a 1 °C decrease in minimum temperature during the cold weather months was associated with 2.2% increase in hospital admission for respiratory infection among children 3–5 years old. A 1 °C increase in diurnal temperature range (DTR) in cold weather was associated with an increase of 1.9% and 1.7% in hospitalisation for all causes and respiratory infection, respectively, among children

- Abstract
Our knowledge of seaweed diversity and biogeography still largely relies on information derived from morphological identifications, but the use of molecular tools is revealing that cryptic diversity is common among algae. Polysiphonia scopulorum is a turf-forming red alga widely reported in tropical and temperate coasts worldwide. The only study based on material collected from its Australian type locality and the Iberian Peninsula indicates that it is a species complex, but the extent of cryptic diversity across its geographical range is not known. To investigate the species diversity in P. scopulorum, the geographical distribution of species-level lineages and their morphological characterization, we collected 135 specimens from Australia, South Africa and southern Europe. Two gene datasets (cox1 and rbcL) were used to delimit species using three methods (GMYC, PTP, ABGD), leading to a consensus result that our collections of the P. scopulorum complex comprise 12 species. Five of these species were resolved in a highly supported clade, while the other seven species were related to other taxonomically accepted species or in unresolved parts of the tree. Morphometric and statistical analysis of a set of ten quantitative characters showed that there are no clear morphological correlates of species boundaries, demonstrating true cryptic diversity in the P. scopulorum complex. Distribution patterns of the 12 species were variable, ranging from species only known from a single site to species with a wide distribution spanning three continents. Our study indicates that a significant level of undiscovered cryptic diversity is likely to be found in algal turfs, a type of seaweed community formed by small entangled species.

- Abstract
The burden of skin infections across all age groups in remote Australian Indigenous communities is currently unknown. In a retrospective audit of 439 residents from two remote communities presenting to health clinics, skin conditions were the most common reason for presentation (1603/7392, 22%) and 330/439 (75%) residents presented at least once with a skin infection. Skin infections are an under-appreciated and dominant reason for presentation to primary healthcare centres in these indigenous communities and public health campaigns to address this should incorporate all age groups.

Purpose The primary objective was to determine safety, toxicity, and a recommended phase II dose regimen of LY2606368, an inhibitor of checkpoint kinase 1, as monotherapy. Patients and Methods This phase I, nonrandomized, open-label, dose-escalation trial used a 3 + 3 dose-escalation scheme and included patients with advanced solid tumors. Intravenous LY2606368 was dose escalated from 10 to 50 mg/m2 on schedule 1 (days 1 to 3 every 14 days) or from 40 to 130 mg/m2 on schedule 2 (day 1 every 14 days). Safety measures and pharmacokinetics were assessed, and pharmacodynamics were measured in blood, hair follicles, and circulating tumor cells. Results Forty-five patients were treated; seven experienced dose-limiting toxicities (all hematologic). The maximum-tolerated doses (MTDs) were 40 mg/m2 (schedule 1) and 105 mg/m2 (schedule 2). The most common related grade 3 or 4 treatment-emergent adverse events were neutropenia, leukopenia, anemia, thrombocytopenia, and fatigue. Grade 4 neutropenia occurred in 73.3% of patients and was transient (typically < 5 days). Febrile neutropenia incidence was low (7%). The LY2606368 exposure over the first 72 hours (area under the curve from 0 to 72 hours) at the MTD for each schedule coincided with the exposure in mouse xenografts that resulted in maximal tumor responses. Minor intra- and intercycle accumulation of LY2606368 was observed at the MTDs for both schedules. Two patients (4.4%) had a partial response; one had squamous cell carcinoma (SCC) of the anus and one had SCC of the head and neck. Fifteen patients (33.3%) had a best overall response of stable disease (range, 1.2 to 6.7 months), six of whom had SCC. Conclusion An LY2606368 dose of 105 mg/m2 once every 14 days is being evaluated as the recommended phase II dose in dose-expansion cohorts for patients with SCC.

This study investigates preexisting and vaccine-induced vector immunity in 30 participants of a Phase-1 VSV-EBOV Ebola vaccine trial. No preexisting immunity was detected, however humoral and cell-mediated immunity against internal VSV proteins was observed in up to 36% of vaccines., In response to the Ebola virus (EBOV) crisis of 2013–2016, a recombinant vesicular stomatitis virus (VSV)–based EBOV vaccine was clinically tested (NCT02283099). A single-dose regimen of VSV-EBOV revealed a safe and immunogenic profile and demonstrated clinical efficacy. While EBOV-specific immune responses to this candidate vaccine have previously been investigated, limited human data on immunity to the VSV vector are available. Within the scope of a phase 1 study, we performed a comprehensive longitudinal analysis of adaptive immune responses to internal VSV proteins following VSV-EBOV immunization. While no preexisting immunity to the vector was observed, more than one-third of subjects developed VSV-specific cytotoxic T-lymphocyte responses and antibodies.

Background We performed a phase I modified 3 + 3 dose escalation study to evaluate the safety and activity of bevacizumab plus gemcitabine and nab-paclitaxel in patients with advanced solid tumours. Methods Patients were given fixed dose gemcitabine plus increasing doses of nab-paclitaxel and bevacizumab. Toxicity, response, and association with VEGF polymorphism was analysed. Results The study enrolled 110 patients who had undergone a median of 3 prior lines of therapy. The median age was 60 years (range, 17–85 years), and 55 patients (50%) had gemcitabine-refractory disease. We observed 3 dose-limiting toxicities during dose escalation and 3 DLTs in expansion cohorts. Dose escalation to 150 mg/m2 nab-paclitaxel and 15 mg/kg bevacizumab with 1000 mg/m2 of gemcitabine was well tolerated with no MTD. One patient with gemcitabine-refractory peritoneal papillary carcinoma had a complete response, 13 patients (13%) had partial responses, and 54 patients (52%) had stable disease ≥12 weeks. Exploratory VEGF single nucleotide polymorphism (SNP) analysis was performed on 13 patients. Conclusions The combination of gemcitabine, nab-paclitaxel, and bevacizumab is safe, well-tolerated, and has activity in advanced malignancies, including gemcitabine-refractory tumours. Based on this study, the recommended phase 2 dose is gemcitabine 1000 mg/m2, nab-paclitaxel 125 mg/m2, and bevacizumab 15 mg/kg. VEGF polymorphism data should be evaluated in future bevacizumab-based trials.

BACKGROUND:Ilorasertib (ABT-348) inhibits Aurora and VEGF receptor (VEGFR) kinases. Patients with advanced solid tumours participated in a phase 1 dose-escalation trial to profile the safety, tolerability, and pharmacokinetics of ilorasertib. METHODS:Ilorasertib monotherapy was administered at 10-180 mg orally once daily (Arm I, n = 23), 40-340 mg orally twice daily (Arm II, n = 28), or 8-32 mg intravenously once daily (Arm III, n = 7), on days 1, 8, and 15 of each 28-day cycle. RESULTS:Dose-limiting toxicities were predominantly related to VEGFR inhibition. The most frequent treatment-emergent adverse events ( > 30%) were: fatigue (48%), anorexia (34%), and hypertension (34%). Pharmacodynamic markers suggested that ilorasertib engaged VEGFR2 and Aurora B kinase, with the VEGFR2 effects reached at lower doses and exposures than Aurora inhibition effects. In Arm II, one basal cell carcinoma patient (40 mg twice daily (BID)) and one patient with adenocarcinoma of unknown primary site (230 mg BID) had partial responses. CONCLUSIONS:In patients with advanced solid tumours, ilorasertib treatment resulted in evidence of engagement of the intended targets and antitumour activity, but with maximum inhibition of VEGFR family kinases occurring at lower exposures than typically required for inhibition of Aurora B in tissue. CLINICAL TRIAL REGISTRATION:NCT01110486.

Background Many studies have indicated the detrimental effect of ambient ozone to respiratory health in different countries. The levels of ozone in Hanoi, Vietnam are frequently above the WHO guideline but very few studies on the effects of ambient ozone on human health have been conducted in this location. This study aimed to examine the effects of ozone on hospital admission for respiratory diseases in Hanoi, by diseases, ages and seasons. Methods Hospital admissions, air pollutants and meteorological data were collected from January 2010 to June 2014. We used generalized linear models and distributed lag linear model to assess the association. In addition to full year analysis, we conducted restricted analysis of the data for two summer (from June-August) and winter (from December-February) seasons and grouped hospital admissions by diseases and ages (all ages, children 0 to 5 years and elderly >65 years). The delayed effect of ozone was assessed using lags of up to 5 days. Results Ozone has a stronger effect on the risk of hospital admission for respiratory diseases and wheeze-associated disorders in the winter. For respiratory diseases, children were affected by ozone more than other age groups in both winter and summer. Each increase of 10 μg/m3 of ozone is associated with an increase of 6.2% risk of admission for respiratory disease among children in the winter and 1.2% in the summer. For wheeze-associated disorders, the elderly group seemed to be more affected by ozone in full year and winter but no significant association was found between ozone and admission for wheeze-associated diseases in any age group. Conclusions Ozone is a risk factor for respiratory admission, especially amongst children under 5 years old in Hanoi, and ozone has a stronger effect in the winter than in the summer in this city.

Purpose: This “3+3” phase I study evaluated the safety, biologic, and clinical activity of lenvatinib, an oral multikinase inhibitor, in patients with solid tumors. Experimental Design: Ascending doses of lenvatinib were administered per os twice daily in 28-day cycles. Safety and response were assessed for all patients. Angiogenic and apoptotic factors were tested as possible biomarkers in an expanded melanoma cohort. Results: Seventy-seven patients were treated in 3 cohorts: 18 with intermittent twice-daily dosing (7 days on, 7 days off) of 0.1–3.2 mg; 33 with twice-daily dosing of 3.2–12 mg; and 26 with twice-daily dosing of 10 mg (expanded melanoma cohort). Maximum tolerated dose was established at 10 mg per os twice daily. Prominent drug-related toxicities included hypertension (43%), fatigue (42%), proteinuria (39%), and nausea (25%); dose-limiting toxicities included hypertension, fatigue, and proteinuria. Twelve patients (15.6%) achieved partial response (PR, n = 9) or unconfirmed PR (uPR, n = 3), and 19 (24.7%) achieved stable disease (SD) ≥23 weeks. Total PR/uPR/SD ≥23 weeks was 40.3% (n = 31). Responses (PR/uPR) by disease were as follows: melanoma, 5 of 29 patients (includes 1 patient with NRAS mutation); thyroid, 3 of 6 patients; pancreatic, 1 of 2 patients; lung, 1 of 1 patients; renal, 1 of 1 patients; endometrial, 1 of 4 patients; and ovarian, 1 of 5 patients. AUC0–24 and Cmax increased dose proportionally. In multivariate Cox proportional hazard model analyses, increased baseline systolic blood pressure and decreased angiopoietin-1 ratio (2 hours:baseline) were associated with longer progression-free survival (PFS) in the expanded melanoma cohort (P = 0.041 and P = 0.03, respectively). Conclusions: The toxicity profile, pharmacokinetics, and antitumor activity of lenvatinib are encouraging. Decreases in the angiopoietin-1 ratio correlated with longer PFS in melanoma patients.

- Abstract
Alkene monooxygenases (MOs) are soluble di-iron-containing enzymes found in bacteria that grow on alkenes. Here, we report improved heterologous expression systems for the propene MO (PmoABCD) and ethene MO (EtnABCD) from Mycobacterium chubuense strain NBB4. Strong functional expression of PmoABCD and EtnABCD was achieved in Mycobacterium smegmatis mc2155, yielding epoxidation activities (62 and 27 nmol/min/mg protein, respectively) higher than any reported to date for heterologous expression of a di-iron MO system. Both PmoABCD and EtnABCD were specialized for the oxidation of gaseous alkenes (C2 to C4), and their activity was much lower on liquid alkenes (C5 to C8). Despite intensive efforts to express the complete EtnABCD enzyme in Escherichia coli, this was not achieved, although recombinant EtnB and EtnD proteins could be purified individually in soluble form. The biochemical function of EtnD as an oxidoreductase was confirmed (1.36 μmol cytochrome c reduced/min/mg protein). Cloning the EtnABCD gene cluster into Pseudomonas putida KT2440 yielded detectable epoxidation of ethene (0.5 nmol/min/mg protein), and this could be stimulated (up to 1.1 nmol/min/mg protein) by the coexpression of cpn60 chaperonins from either Mycobacterium spp. or E. coli Successful expression of the ethene MO in a Gram-negative host was validated by both whole-cell activity assays and peptide mass spectrometry of induced proteins seen on SDS-PAGE gels.IMPORTANCE Alkene MOs are of interest for their potential roles in industrial biocatalysis, most notably for the stereoselective synthesis of epoxides. Wild-type bacteria that grow on alkenes have high activities for alkene oxidation but are problematic for biocatalysis, since they tend to consume the epoxide products. Using recombinant biocatalysts is the obvious alternative, but a major bottleneck is the low activities of recombinant alkene MOs. Here, we provide new high-activity recombinant biocatalysts for alkene oxidation, and we prov

- Abstract
Fucoidans from brown macroalgae have beneficial biomedical properties but their use as pharma products requires homogenous oligomeric products. In this study, the action of five recombinant microbial fucoidan degrading enzymes were evaluated on fucoidans from brown macroalgae: Sargassum mcclurei, Fucus evanescens, Fucus vesiculosus, Turbinaria ornata, Saccharina cichorioides, and Undaria pinnatifida. The enzymes included three endo-fucoidanases (EC 3.2.1.-GH 107), FcnA2, Fda1, and Fda2, and two unclassified endo-fucoglucuronomannan lyases, FdlA and FdlB. The oligosaccharide product profiles were assessed by carbohydrate-polyacrylamide gel electrophoresis and size exclusion chromatography. The recombinant enzymes FcnA2, Fda1, and Fda2 were unstable but were stabilised by truncation of the C-terminal end (removing up to 40% of the enzyme sequence). All five enzymes catalysed degradation of fucoidans containing α(1→4)-linked l-fucosyls. Fda2 also degraded S. cichorioides and U. pinnatifida fucoidans that have α(1→3)-linked l-fucosyls in their backbone. In the stabilised form, Fda1 also cleaved α(1→3) bonds. For the first time, we also show that several enzymes catalyse degradation of S. mcclurei galactofucan-fucoidan, known to contain α(1→4) and α(1→3) linked l-fucosyls and galactosyl-β(1→3) bonds in the backbone. These data enhance our understanding of fucoidan degrading enzymes and their substrate preferences and may assist development of enzyme-assisted production of defined fuco-oligosaccharides from fucoidan substrates.

TPS2669 Background: Drugs targeting pathogen associated molecular patterns are an attractive strategy to stimulate the immune system. Toll-like receptors (TLR) have generated significant interest as an effective means of stimulating the immune system that result in the killing of tumor cells. TLR-9 agonists can function to promote an early immune response and are an appealing partner for combination with checkpoint blockade to improve immune activation. Lefitolimod (MGN1703) is a covalently closed dumbbell-shaped DNA molecule that functions as a TLR-9 agonist. We developed a clinical trial combining lefitolimod with ipilimumab (anti-CTLA4) in patients with advanced malignancies. In the dose-escalation phase 19 patients were enrolled and no DLTs were encountered. Safety data and maximum planned dose level of lefitolimod at 120mg weekly and ipilimumab 3mg/kg every 3 weeks was previously presented. Adverse events related to the combination included fatigue, appetite loss, rash, and anemia. Methods: This trial (NCT02668770) was designed to evaluate the safety profile and maximum tolerated dose of lefitolimod with ipilimumab. A 3+3 trial design was used to establish safety of the combination at each dose level and guide the decision to escalate dose. Lefitolimod is administered via subcutaneous (SC) injection weekly while ipilimumab is given at 3mg/kg intravenous on day 8 of each 3 week cycle. Lefitolimod starting dose was 15mg SC weekly with 3 dose level escalations up to 120mg SC weekly. Patients receive treatment for 4 cycles (total 12 weeks) with the combination, and those with stable disease or response were eligible to remain on lefitolimod therapy for up to 1 year. Eligible patients have a metastatic or unresectable solid tumor refractory to standard therapies, ECOG ≤ 2, and normal organ and bone marrow function. Patients are allowed to have received prior checkpoint blockade agents. Enrollment in expansion cohorts in ongoing. To better understand relevant immunologic changes associated with treatment, paired pre- and post-treatment biopsies of target lesions and peripheral blood collection during treatment is required for target expansion cohort patient populations. In addition to evaluating target patient populations at the combination dose established during escalation, an expansion cohort for patients with cutaneous metastases involves combination treatment with intratumoral delivery of lefitolimod. Clinical trial information: NCT02668770.

Background: We aimed to study the prevalence of oral sex and its possible association with human papillomavirus (HPV) 16 infection in the development of oropharyngeal cancer in the US population for possible prevention. Methods: We conduct a systemic review on the prevalence of oral sex among Americans among different age groups, the prevalence of HPV 16 infection reported in oropharyngeal cancer, and correlation between oral sex and oropharyngeal cancer. Results: Oral sex is prevalent among adolescents and sexually active adults. Sixty percent of oropharyngeal cancer reported in the United States is associated with HPV 16 infections. Individuals who practiced oral sex with multiple partners are at risk for developing oropharyngeal cancer and need to be informed about practicing safe sex or getting vaccination. Conclusion: Family physicians will play a key role in prevention and educating the public about the risk of oral sex.

While the effects of ambient air pollution on health have been studied extensively in many developed countries, few studies have been conducted in Vietnam, where the population is exposed to high levels of airborne particulate matter. The aim of our study was to examine the short-term effects of PM10, PM2.5, and PM1 on respiratory admissions among young children in Hanoi. Data on daily admissions from the Vietnam National Hospital of Paediatrics and daily records of PM10, PM2.5, PM1 and other confounding factors as NO2, SO2, CO, O3 and temperature were collected from September 2010 to September 2011. A time-stratified case-crossover design with individual lag model was applied to evaluate the associations between particulate air pollution and respiratory admissions. Significant effects on daily hospital admissions for respiratory disease were found for PM10, PM2.5 and PM1. An increase in 10 μg/m3 of PM10, PM2.5 or PM1 was associated with an increase in risk of admission of 1.4%, 2.2% or 2.5% on the same day of exposure, respectively. No significant difference between the effects on males and females was found in the study. The study demonstrated that infants and young children in Hanoi are at increased risk of respiratory admissions due to the high level of airborne particles in the city's ambient air.

Air pollution has become an alarming issue in Vietnam recently; however, there was only one study so far on the effects of ambient air pollution on population health. Our study aimed to investigate the short-term effects of air pollutants including PM10, NO2, SO2, and O3 on respiratory and cardiovascular hospitalizations in Ho Chi Minh City (HCMC), the largest city in Vietnam. Data on hospitalization from the two largest hospitals in HCMC and daily records of PM10, NO2, SO2, O3 and meteorological data were collected from February 2004 to December 2007. A time-series regression analysis with distributed lag model was applied for data analysis. Changes in levels of NO2 and PM10 were strongly associated with hospital admissions for both respiratory and cardiovascular diseases (CVD); whereas levels of SO2 were only moderately associated with respiratory and CVD hospital admissions and O3 concentration was not associated with any of them. For a 10μg/m(3) increase of each air pollutant, the risk of respiratory admissions increased from 0.7% to 8% while the risk of CVD admissions increased from 0.5% to 4%. Females were found to be more sensitive than males to exposure to air pollutants in regard to respiratory diseases. In regard to CVD, females (RR, 1.04, 95% CI, 1.01-1.07) had a slightly higher risk of admissions than males (RR, 1.03, 95% CI, 1-1.06) to exposure to NO2. In contrast, males (RR, 1.007, 95%CI, 1-1.01) had a higher risk of admission than females (RR, 1.004, 95%CI, 1.001-1.007) to exposure to PM10. People in the age group of 5-65year-olds had a slightly higher risk of admissions caused by air pollutants than the elderly (65+years old) except for a significant effect of PM10 on the risk of cardiovascular admissions was found for the elderly only.

Dose Level (DL)1: lenvatinib 20 mg, TMZ 100 mg/m 2 ; DL2: lenvatinib 24 mg, TMZ 100 mg/m 2 ; DL3: lenvatinib 24 mg, TMZ 150 mg/m 2 . Adverse events (AEs) were recorded and tumor response assessed per RECIST 1.0. Results: Dose-limiting toxicity occurred in 1 of 32 treated patients (DL1); MTD was not reached. The highest dose administered was lenvatinib 24 mg + TMZ 150 mg/m 2 . Most common treatment-related AEs included fatigue (56.3%), hypertension (53.1%), and proteinuria (46.9%). Overall objective response rate was 18.8% (6 patients), all partial response; (DL1, n = 1; DL3, n = 5). Stable disease (SD) ≥ 16 weeks was observed in 28.1% of patients (DL1 and DL2, n = 1 each; DL3, n = 7); 12.5% of patients had SD ≥ 23 weeks. Single and repeat-dose pharmacokinetics of lenvatinib were comparable across cycles and with concomitant TMZ administration. Conclusion: Lenvatinib 24 mg/day + TMZ 150 mg/m 2 /day (days 1–5) demonstrated modest clinical activity, an acceptable safety profile, and was administered without worsening of either lenvatinib- or TMZ-related toxicities in this patient group.

This study investigated the association between geographic region and blood lead levels (BLLs) in US children, as well as trends in this relationship, using data from the National Health and Nutrition Examination Survey (NHANES).SAS® and SUDAAN® software programs were utilized to develop linear regression models adjusted for several factors associated with BLLs.The largest decline in BLLs was observed in Northeastern children, while the percentage of children with elevated blood lead levels decreased the most for the West and Northeast. Lead levels of Northeastern children were still higher than those of children living in the West. However, levels were not different among children residing in the Northeast, Midwest, and South, and the blood lead concentrations were less than 5 μg/dL for all but one subgroup of children and less than 2 μg/dL for70% of the subgroups. More importantly, the effects of different risk factors for higher blood lead levels varied by region even after adjusting for all other covariates.The results of this study not only provide relevant and current blood lead levels for US children that can be used as reference values to evaluate biomonitoring data, but can also be used to help direct prevention and surveillance strategies to reduce lead in the environment of at-risk children.

Background/Aims: To identify physician selection factors in the treatment of locally advanced head and neck cancer and how treatment outcome is affected by Tumor Board recommendations. Methods: A retrospective analysis of 213 patients treated for locally advanced head and neck cancer in a single institution was performed. All treatments followed Tumor Board recommendations: 115 patients had chemotherapy and radiation, and 98 patients received postoperative radiation. Patient characteristics, treatment toxicity, locoregional control and survival between these two treat- ment groups were compared. Patient survival was compared with survival data reported in randomized studies of locally advanced head and neck cancer. Results: There were no differences in comorbidity factors, and T or N stages between the two groups. A statistically significant number of patients with oropharyngeal and oral cavity tumors had chemoradiation and postoperative radiation, respectively (p < 0.0001). Grade 3–4 toxicities during treatment were 48 and 87% for the postoperative radiation and chemoradiation groups, respectively (p = 0.0001). There were no differences in survival, locoregional recurrences and distant metastases between the two groups. Patient survival was comparable to survival rates reported by randomized studies of locally advanced head and neck cancer. Conclusion: Disease sites remained the key determining factor for treatment selection. Multidisciplinary approaches provided optimal treatment outcome for locally advanced head and neck cancer, with overall survival in these patients being comparable to that reported in randomized clinical trials.

The effectiveness of the cough reflex in patients who aspirated following radiation for head and neck cancer was evaluated in 89 patients (49 chemoradiation, 33 postoperative radiation, and 7 radiation alone). All patients had modified barium swallow because of dysphagia. The cough reflex was graded as present and effective, ineffective, intermittently effective, or absent. All patients were cancer-free at the time of the swallowing study. The cough reflex was present and effective in 46 patients (52%), ineffective in 17 patients (19%), and absent in 26 patients (29%) on initial investigation. Among the 43 patients who had ineffective or absent cough reflex, their treatment was chemoradiation (26), postoperative radiation (13), and radiation alone (4). In 30 patients who had sequential modified barium swallow, the cough reflex was constantly effective, ineffective, or intermittently effective in 12 (40%), 13 (43%), and 5 (17%) patients, respectively. The cough reflex was frequently ineffective or absent in patients who aspirated following radiation for head and neck cancer. Cough may also be intermittently ineffective to protect the airways following radiation.

Purpose The aim of this study was to assess the survival, pattern of failure, morbidity, and prognostic factors of concurrent chemoradiation for locally advanced oropharyngeal cancer. Materials and methods A retrospective survey of patients who underwent chemotherapy and radiation for locally advanced oropharyngeal carcinoma at the Veteran Affairs North Texas Health Care System, Dallas, Tex. Results Between December 1999 and September 2004, 48 patients with locally advanced oropharyngeal cancer underwent concurrent chemotherapy and radiation. At a median follow-up of 23 months, the 3- and 5-year survival for the whole group were, respectively, 52% and 41%. Seventeen patients (35%) developed recurrences. There were 12 (25%) locoregional failures (6 local failures alone and 6 local and regional failures). Distant metastases developed in 8 patients (5 alone, 3 associated with locoregional failures). Four patients (8%) developed second primaries. No difference was observed in survival between base of tongue and tonsillar carcinoma (P = .32). The 5-year survival for T1-T2 and T3-T4 tumors was, respectively, 84% and 27% (P = .01). No patient with T1-T2 tumors developed distant metastases (P = .04). Forty-five patients (94%) developed toxicity grade 3 to 4 (40 mucositis and 26 hematological). The median weight loss was 18 lb (range, 0–47 lb). Eight patients (16%) developed aspiration pneumonia during and after treatment. Five patients (10%) died of aspiration (2 during and 3 post treatment). Four patients (8%) developed esophageal strictures requiring repeated dilatations post treatment. Two patients had radionecrosis (1 soft tissue and 1 bone) requiring hyperbaric oxygen. Eighteen patients (37%) had prolonged tube feedings (>3 months) after treatments because of severe dysphagia or aspiration. Conclusion Concurrent chemoradiation provided good locoregional control for locally advanced oropharyngeal carcinoma. Patients with small tumors (T1-T2) had excellent survival. The poor prognosis associated with large tumors may be due to the risk of developing distant metastases. Acute and late toxicities remained significant. Aspiration pneumonia and severe dysphagia were the most prevalent complications of the combined modality approach.

Background: To evaluate the impact of chemoradiation and postoperative radiation on patients’ quality of life (QOL) in a single institution. Methods: A retrospective analysis of 101 patients who had treatment for locally advanced head and neck cancer in a single institution. Forty-seven patients had chemotherapy and radiation, 54 patients underwent postoperative radiation. QOL was assessed with the University of Washington (UW), and the Hospital Anxiety (HA) and Depression (HD) questionnaires. All patients were free of disease at the survey time. Results: Mean and median UW scores were not different between the 2 groups: chemoradiation (65/67), postoperative radiation (62/63). Mean and median HA scores were 7.6/7 (chemoradiation), and 8.3/8 (postoperative radiation). Mean and median HD scores were 6.7/7 (chemoradiation), and 7.1/7 (postoperative radiation). Forty-four patients developed complications, with mean/median UW, HA, and HD scores of 55/55, 9.9/8, and 8.9/9, respectively. These scores were significantly different compared to the 57 patients without complications: 70/70 (p = 0.0001), 6.5/6 (p = 0.001), and 8.9/9 (p = 0.0001). Conclusion: There was no significant difference in QOL between chemoradiation and postoperative radiation in this retrospective study with a relatively short follow-up in the chemoradiation group. In addition, there were more patients with resectable disease in the postoperative group which may explain the lack of difference in QOL between the two groups. Patients who developed complications following treatment experienced lower QOL, more anxiety and depression. Our study raised the need to conduct a prospective randomized study to assess the real impact of chemoradiation and postoperative radiation on patients’ QOL.
