RESUMO
Mirror game (MG) is an exercise in which participants imitate each other. Our study explored its spontaneous behavioral consequences after performance. In a baseline (BL) phase, two participants performed a joint Simon task. Then, they performed a lure task during which we measured the interpersonal distance they spontaneously adopted. The BL phase was followed by two phases (in counterbalanced order). The MG phase started with a MG, before a procedure like the BL phase. The individual movement (IM) phase started with movements performed alone before a procedure like the BL phase. Interpersonal distance analysis suggested that MG enhanced spontaneous approach toward the partner, whereas IM induced spontaneous avoidance. Moreover, the joint Simon effect (JSE) tended to be smaller after IM, suggesting a decreasing inclination to integrate the partner's response in one's own action plan. Furthermore, in IM phase, JSE decreased as interpersonal distance increased.
RESUMO
BACKGROUND: A standard treatment for fit, older patients with recurrent or metastatic head and neck squamous cell carcinoma (HNSCC) is yet to be established. In the previous EXTREME trial, few older patients were included. We aimed to evaluate the efficacy and tolerance of an adapted EXTREME regimen in fit, older patients with recurrent or metastatic HNSCC. METHODS: This single-arm, phase 2 study was done at 22 centres in France. Eligible patients were aged 70 years or older and assessed as not frail (fit) using the ELAN Geriatric Evaluation (EGE) and had recurrent or metastatic HNSCC in the first-line setting that was not eligible for local therapy (surgery or radiotherapy), and an Eastern Cooperative Oncology Group performance status of 0-1. The adapted EXTREME regimen consisted of six cycles of fluorouracil 4000 mg/m2 on days 1-4, carboplatin with an area under the curve of 5 on day 1, and cetuximab on days 1, 8, and 15 (400 mg/m2 on cycle 1-day 1, and 250 mg/m2 subsequently), all intravenously, with cycles starting every 21 days. In patients with disease control after two to six cycles, cetuximab 500 mg/m2 was continued once every 2 weeks as maintenance therapy until disease progression or unacceptable toxicity. Granulocyte colony-stimulating factor was systematically administered and erythropoietin was recommended during chemotherapy. The study was based on the two-stage Bryant and Day design, combining efficacy and toxicity endpoints. The primary efficacy endpoint was objective response rate at week 12 after the start of treatment, assessed by central review (with an unacceptable rate of ≤15%). The primary toxicity endpoint was morbidity, defined as grade 4-5 adverse events, or cutaneous rash (grade ≥3) that required cetuximab to be discontinued, during the chemotherapy phase, or a decrease in functional autonomy (Activities of Daily Living score decrease ≥2 points from baseline) at 1 month after the end of chemotherapy (with an unacceptable morbidity rate of >40%). Analysis of the coprimary endpoints, and of safety in the chemotherapy phase, was based on the per-protocol population, defined as eligible patients who received at least one cycle of the adapted EXTREME regimen. Safety in the maintenance phase was assessed in all patients who received at least one dose of cetuximab as maintenance therapy. The study is registered with ClinicalTrials.gov, NCT01864772, and is completed. FINDINGS: Between Sept 27, 2013, and June 20, 2018, 85 patients were enrolled, of whom 78 were in the per-protocol population. 66 (85%) patients were male and 12 (15%) were female, and the median age was 75 years (IQR 72-79). The median number of chemotherapy cycles received was five (IQR 3-6). Objective response at week 12 was observed in 31 patients (40% [95% CI 30-51]) and morbidity events were observed in 24 patients (31% [22-42]). No fatal adverse events occurred. Four patients presented with a decrease in functional autonomy 1 month after the end of chemotherapy versus baseline. During chemotherapy, the most common grade 3-4 adverse events were haematological events (leukopenia [22 patients; 28%], neutropenia [20; 26%], thrombocytopenia [15; 19%], and anaemia [12; 15%]), oral mucositis (14; 18%), fatigue (11; 14%), rash acneiform (ten; 13%), and hypomagnesaemia (nine; 12%). Among 44 patients who received cetuximab during the maintenance phase, the most common grade 3-4 adverse events were hypomagnesaemia (six patients; 14%) and acneiform rash (six; 14%). INTERPRETATION: The study met its primary objectives on objective response and morbidity, and showed overall survival to be as good as in younger patients treated with standard regimens, indicating that the adapted EXTREME regimen could be used in older patients with recurrent or metastatic HNSCC who are deemed fit with use of a geriatric evaluation tool adapted to patients with head and neck cancer, such as the EGE.

BACKGROUND: Chemoradiotherapy with high-dose cisplatin (HD-Cis: 100 mg/m2 q3w for three cycles) is the standard of care (SOC) in locally advanced head and neck squamous cell carcinoma (LA-HNSCC). Cumulative delivered dose of cisplatin is prognostic of survival, even beyond 200 mg/m2 but high toxicity compromises its delivery. AIM: Cisplatin fractionation may allow, by decreasing the peak serum concentration, to decrease toxicity. To date, no direct comparison was done of HD-Cis versus fractionated high dose cisplatin (FHD-Cis). METHODS: This is a multi-institutional randomized phase II trial, stratified on postoperative or definitive chemoradiotherapy, comparing HD-Cis to FHD-Cis (25 mg/m2/d d1-4 q3w for 3 cycles) in patients with LA-HNSCC. The primary endpoint was the cumulative delivered cisplatin dose. RESULTS: Between December 2015 and April 2018, 124 patients were randomized. Median cisplatin cumulative delivered dose was 291 mg/m2 (IQR: 251;298) in the FHD-Cis arm and 274 mg/m2 (IQR: 198;295) in the HD-Cis arm (P = 0.054). The proportion of patients receiving a third cycle of cisplatin was higher, with a lower proportion of grade 3-4 acute AEs in the FHD-Cis arm compared to the HD-Cis arm: 81 % vs. 64 % (P = 0.04) and 10 % vs. 17 % (P = 0.002), respectively. With a median follow-up of 48 months (IQR: 41;55), locoregional failure rate, PFS and OS were similar between the two arms. CONCLUSION: Although the primary endpoint was not met, FHD-Cis allowed more cycles of cisplatin to be delivered with lower toxicity, when compared to SOC. FHD-Cis concurrently with RT is a treatment option which deserves further consideration.

INTRODUCTION: Thymomas are rare intrathoracic malignancies that can relapse after surgery. Whether or not Post-Operative RadioTherapy (PORT) should be delivered after surgery remains a major issue. RADIORYTHMIC is an ongoing, multicenter, randomized phase 3 trial addressing this question in patients with completely R0 resected Masaoka-Koga stage IIb/III thymoma. Experts in the field met to develop recommendations for PORT. METHODS: A scientific committee from the RYTHMIC network identified key issues regarding the modalities of PORT in completely resected thymoma. A DELPHI method was used to question 24 national experts, with 115 questions regarding the following: (1) imaging techniques, (2) clinical target volume (CTV) and margins, (3) dose constraints to organs at risk, (4) dose and fractionation, and (5) follow-up and records. Consensus was defined when opinions reached more than or equal to 80% agreement. RESULTS: We established the following recommendations: preoperative contrast-enhanced computed tomography (CT) scan is recommended (94% agreement); optimization of radiation delivery includes either a four-dimensional CT-based planning (82% agreement), a breath-holding inspiration breath-hold-based planning, or daily control CT imaging (81% agreement); imaging fusion based on cardiovascular structures of preoperative and planning CT scan is recommended (82% agreement); right coronary and left anterior descending coronary arteries should be delineated as cardiac substructures (88% agreement); rotational RCMI/volumetric modulated arc therapy is recommended (88% agreement); total dose is 50 Gy (81% agreement) with 1.8 to 2 Gy per fraction (94% agreement); cardiac evaluation and follow-up for patients with history of cardiovascular disease are recommended (88% agreement) with electrocardiogram and evaluation of left ventricular ejection fraction at 5 years and 10 years. CONCLUSION: This is the first consensus for PORT in thymoma. Implementation will help to harmonize practices.
