ABSTRACT

Historic pollination networks are important to understand interactions between different plant and pollinator species, as well as to differentiate between causes and consequences of present insect population decline. Natural history collections in museums store biological proxy data, which is used to reconstruct historic pollination networks of bumble bees. Four bumble bee species (Bombus terrestris, B. ruderatus, B. hortorum and B. subterraneus) were introduced to Aotearoa New Zealand in 1885 specifically for pollination purposes. Pollen samples were collected from museum specimens of three of the four NZ species of bumble bee (excluding B. subterraneus) collected between 1954 and 1972 from 56 locations across the South Island, New Zealand. The most common plants identified on all three bumble bee species were Calluna vulgaris (heather), Ulex (gorse), Cytisus (broom), and Trifolium repens (white clover). However, all three bumble bee species also carried pollen from several native plants (e.g. Arthropodium, Weinmannia, Plagianthus, Quintinia, Veronica, Melicytus) and potentially had been involved in the pollination of these species. This study adds new plant species known to be foraged upon by bumble bees in Aotearoa New Zealand. Further studies on pollination networks in New Zealand will help us understand any changes in host plant preferences over time and after the time period covered by this study.

ABSTRACT

OBJECTIVE: Induction chemotherapy in head and neck squamous cell carcinoma (HNSCCA) has principally been studied prior to radiation therapy. We evaluated pre-operative induction therapy followed by surgery followed by risk-adapted adjuvant therapy. This report details the mature 5-year survival statistics, clinical and functional outcomes. METHODS: An IRB-approved single institution prospective phase II clinical trial from October 2012 to November 2016 was conducted for patients with transorally-resectable American Joint Committee on Cancer 7th ed. stage III/IV HNSCCA. Patients were treated once weekly for six weeks with a multi-drug induction regimen of carboplatin, paclitaxel and daily lapatinib followed by transoral surgery and neck dissection. Patients were then stratified based on pathologic response to either observation or adjuvant therapy. Survival statistics and functional patient outcomes were analyzed. Specifically, peri-operative outcomes were analyzed and compared to a matched surgical cohort. RESULTS: 38/40 enrolled patients completed trial therapy. Median hospital stay was 3 days with 9/38 patients receiving a PEG (median 46 days). Median NPO status was 1 day, with a median return to a regular diet in 16 days. Mean patient weight was well preserved from pretreatment to 1 year after surgery (85.1 kg (95% CI 79.6-90.7) vs 83.1 kg (95% CI 77.7-88.6 kg) respectively). Of the 38 patients who completed trial therapy; DSS, PFS and OS were 100%, 97% and 97% respectively with median follow up of 4.9 years (3.33-7.25). CONCLUSION: Transoral surgery was feasible following this novel induction regimen with excellent peri-operative, functional and longterm survival outcomes.

ABSTRACT

PURPOSE: To report the results of a phase II clinical trial of de-intensified chemoradiotherapy for patients with human papillomavirus-associated oropharyngeal squamous cell carcinoma. MATERIALS AND METHODS: Major inclusion criteria were (1) having American Joint Committee on Cancer (AJCC) 7th edition T0-T3, N0-N2c, M0 (AJCC 8th edition T0-T3, N0-N2, M0), (2) being p16 positive, and (3) reporting minimal or remote smoking history. Treatment was limited to 60 Gy intensity-modulated radiotherapy with concurrent intravenous cisplatin 30 mg/m2 once per week. Patients with T0-T2 N0-1 (AJCC 7th edition) did not receive chemotherapy. All patients had a 10- to 12-week post-treatment positron emission tomography/computed tomography to assess for neck dissection. The primary end point was 2-year progression-free survival. Secondary end points included 2-year local-regional control, distant metastasis-free survival and overall survival, and patient-reported outcomes (European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire and the patient-reported outcomes version of the Common Terminology Criteria for Adverse Events). RESULTS: One hundred fourteen patients were enrolled (median follow-up of 31.8 months), with 81% having a minimum follow-up of 2 years. Eighty percent of patients had 10 or fewer tobacco pack-years. Two-year local-regional control, distant metastasis-free survival, progression-free survival, and overall survival were as follows: 95%, 91%, 86%, and 95%, respectively. Mean pre- and 2-year post-treatment European Organisation for Research and Treatment of Cancer quality of life scores were as follows: global, 79/84 (lower worse); swallowing, 8/9 (higher worse); and dry mouth, 14/45 (higher worse). Mean pre- and 2-year post-treatment patient-reported outcomes version of the Common Terminology Criteria for Adverse Events scores (0 to 4 scale, higher worse) were as follows: swallowing, 0.5/0.7, and dry mouth, 0.4/1.3. Thirty-four percent of patients required a feeding tube (median, 10.5 weeks; none permanent). There were no grade 3 or higher late adverse events. CONCLUSION: Clinical outcomes with a de-intensified chemoradiotherapy regimen of 60 Gy intensity-modulated radiotherapy with concurrent low-dose cisplatin are favorable in patients with human papillomavirus-associated oropharyngeal squamous cell carcinoma. Neither neoadjuvant chemotherapy nor routine surgery is needed to obtain favorable results with de-escalation.

ABSTRACT

OBJECTIVES: The current exploratory cross-sectional study was designed to examine and characterize survivorship issues among patients treated with radiation for head and neck cancer with regard to dental health, shoulder-neck dysfunction, and overall quality of life (QOL). METHODS: Patients (N = 58) being seen for follow-up at a radiation oncology clinic at least 1 year beyond the end of treatment completed three survey questionnaires regarding general QOL as well as dental health issues and shoulder-neck dysfunction. The questionnaires were scored and univariate analyses were performed using the variables of age, radiation dosage, definitive radiation + neck dissection versus definitive surgery + postoperative radiation, and chemotherapy. RESULTS: Median follow-up was 2.5 years. Of 58 patients, 35% reported having more problems with their general dental health as compared to before treatment and 38% reported having pain at night in the neck/shoulder after treatment. With regard to pretreatment counseling, 79% of patients reported being counseled about their dental health prior to treatment, while 31% reported being counseled about possible shoulder-neck dysfunction. Patients younger than 65, patients receiving higher doses of radiation, and patients undergoing definitive surgery + postoperative radiation reported more functional and symptomatic issues. CONCLUSION: Patients treated with radiation for head and neck cancer face a number of survivorship issues, including problems with dental health and shoulder-neck dysfunction, and are not necessarily thoroughly counseled about these issues prior to treatment. Patients younger than 65, patients receiving higher doses of radiation, and patients undergoing definitive surgery + postoperative radiation may experience more survivorship issues. LEVEL OF EVIDENCE: IV.

ABSTRACT

BACKGROUND: The objective of this study was to demonstrate the feasibility and efficacy of induction chemotherapy, surgery, and pathology-guided adjuvant therapy to treat transorally resectable squamous head and neck cancer. METHODS: Patients had squamous head and neck cancer that was resectable by the transoral route and advanced-stage disease (American Joint Committee on Cancer stage III-IV, T3-T4 tumors, and/or positive lymph nodes). They received treatment with weekly carboplatin at an area under the curve of 2, plus paclitaxel 135 mg/m2 , and daily lapatinib 1000mg for 6 weeks followed by surgical resection. Pathology that revealed margins <5 mm, extracapsular extension, N2a of N2b lymph node status, perineural invasion, or lymphovascular space invasion resulted in adjuvant radiotherapy concurrent with weekly cisplatin. Pathology with N2c/N3 lymph node status or positive margins resulted in radiation with bolus cisplatin. The primary endpoint was the clinical response rate to induction chemotherapy, and a key secondary endpoint was feasibility. RESULTS: Toxicity was modest, and 37 of 40 patients completed study procedures as planned. The clinical response rate was 93%, the pathologic complete response rate was 36%, and the clinical response did not predict for a pathologic complete response. No patient on study follow-up has recurred or died. Twenty-nine of 39 patients who underwent surgery avoided radiation. Speech and swallowing function were well preserved. CONCLUSIONS: The study met both its primary efficacy endpoint and the secondary feasibility endpoint. Neoadjuvant, systemic therapy and surgical resection followed by risk-adapted adjuvant therapy resulted in high response rates and excellent long-term outcomes and should be further studied.

ABSTRACT

BACKGROUND: The optimal technique to detect venous reflux requires a patient to be standing with weight on one leg while the other leg is scanned for superficial venous reflux (standing position [SP] technique). This represents a significant hardship for a subset of patients who are unable to stand and adequately maintain their balance. This study examines the predictability of identifying venous reflux using a reverse Trendelenburg 60° (RT-60) when compared with the SP in the great saphenous vein (GSV) and small saphenous vein (SSV). METHODS: After obtaining informed consent, consecutive symptomatic patients were studied for venous reflux in the GSV and SSV using both SP and RT-60 during the same visit to the diagnostic laboratory. Reflux was analyzed in both SSV (proximal, mid, and distal segments) and GSV (proximal, mid-thigh, distal-thigh, and below-the-knee segments). Reflux was defined as duration of retrograde venous flow >0.5 seconds following rapid cuff deflation. Patients with heart failure, prior limb surgery, history of deep vein thrombosis, cellulitis, known severe pulmonary hypertension, end-stage renal disease, lymphedema, or trauma were excluded. We calculated the percentage of segments that had reflux on RT-60 out of those with reflux on SP, and the percentage of no reflux on RT-60 out of those with no reflux on SP. RESULTS: A total of 33 patients (56 limbs, 252 segments) were included in this analysis. Mean age was 65 ± 12.4 years and 54.5% were male. All patients were symptomatic (mean clinical, etiology, anatomy, pathophysiology [CEAP] class, 3.5). Deep venous reflux was present in 3/33 patients (9.1%). Of the patients enrolled, 93.9% noted worsening swelling of their lower extremities with standing up and 53.6% of limbs were CEAP class IV or higher. All limbs with no reflux on RT-60 had no reflux using the SP and 48/49 limbs (98%) with reflux on SP also had reflux on the RT-60. CONCLUSION: RT-60 appears to capture 98% and 100% of positive and negative reflux scans on SP, respectively, when GSV and SSV were evaluated. These findings, however, may not apply to the remainder of the venous system of the lower extremity, where SP may continue to be the standard for venous reflux evaluation.

ABSTRACT

IMPORTANCE: Agreement between patient- and practitioner-reported toxic effects during chemoradiotherapy for head and neck cancer is unknown. OBJECTIVE: To compare patient-reported symptom severity and practitioner-reported toxic effects among patients receiving chemoradiotherapy for head and neck cancer. DESIGN, SETTING, AND PARTICIPANTS: Forty-four patients participating in a phase 2 trial of deintensified chemoradiotherapy for oropharyngeal carcinoma were included in the present study (conducted from February 8, 2012, to March 2, 2015). Most treatment (radiotherapy, 60 Gy, with concurrent weekly administration of cisplatin, 30 mg/m2) was administered at academic medical centers. Included patients had no prior head and neck cancers, were 18 years or older, and had a smoking history of 10 pack-years or less or more than 10 pack-years but 30 pack-years or less and abstinent for the past 5 years. Cancer status was untreated human papillomavirus or p16-positive squamous cell carcinoma of the oropharynx or unknown head and neck primary site; and cancer staging was category T0 to T3, category N0 to N2c, M0, and Eastern Cooperative Oncology Group performance status 0 to 1. Baseline, weekly, and posttreatment toxic effects were assessed by physicians or nurse practitioners using National Cancer Institute's Common Terminology Criteria for Adverse Events (CTCAE), version 4.0. Patient-reported symptom severity was measured using the Patient-Reported Outcomes version of the CTCAE (PRO-CTCAE). Descriptive statistics were used to characterize raw agreement between CTCAE grades and PRO-CTCAE severity ratings. INTERVENTIONS: Baseline, weekly, and posttreatment toxic effects assessed using CTCAE, version 4.0, and PRO-CTCAE. MAIN OUTCOMES AND MEASURES: Raw agreement indices between patient-reported toxic effects, including symptom frequency, severity, and interference with daily activities (score range, 0 [none] to 4 [very severe]), and practitioner-measured toxic effects, including swallowing, oral pain, and hoarseness (score range, 1 [mild] to 5 [death]). RESULTS: Of the 44 patients included in the analysis (39 men, 5 women; mean [SD] age, 61 [8.4] years), there were 327 analyzable pairs of CTCAE and PRO-CTCAE symptom surveys and no treatment delays due to toxic effects. Patient-reported and practitioner-reported symptom severity agreement was high at baseline when most symptoms were absent but declined throughout treatment as toxic effects increased. Most disagreement was due to lower severity of toxic effects reported by practitioners (eg, from 45% agreement at baseline to 27% at the final week of treatment for pain). This was particularly noted for domains that are not easily evaluated by physical examination, such as anxiety and fatigue (eg, severity of fatigue decreased from 43% at baseline to 12% in the final week of treatment). CONCLUSIONS AND RELEVANCE: Practitioner-reported toxic effects are lower than patient self-reports during head and neck chemoradiotherapy. The inclusion of patient-reported symptomatic toxic effects provides information that can potentially enhance clinical management and improve data quality in clinical trials.
