RESUMEN
PURPOSE: The role of chemotherapy has not been established in the treatment of metastatic squamous cell oesophageal cancer (mESCC). PATIENTS AND METHODS: E-DIS is a discontinuation trial, aimed at estimating efficacy, quality of life and safety of chemotherapy continuation (CT-CONT) in patients with mESCC who are free from progression after a selection phase of chemotherapy. The primary end-point was overall survival. RESULTS: Sixty-seven patients were randomised. The 9-month survival rate was 50% (85% confidence interval [CI]: 37-62%) and 48% (85% CI: 35-60%) in the CT-CONT arm and in the chemotherapy discontinuation (CT-DISC) arm, respectively. The time until definitive deterioration of the global health status (European Organisation for Research and Treatment of Cancer [EORTC] core quality of life questionnaire) was 6.6 months (95% CI: 3.3-12.4) for the CT-CONT arm and 4.2 months (95% CI: 2.9-6.3) for the CT-DISC arm, with a hazard ratio (HRCT-DISC/CT-CONT) = 1.44 (95% CI: 0.82-2.53). We observed a beneficial trend in favour of CT-CONT (HR > 1) for most dimensions, including an improvement for three dimensions (dysphagia, eating and oesophageal pain) of the EORTC Oesophageal Cancer Module QLQ-OES18. CONCLUSION: CT-CONT provides an overall survival rate that is similar to CT-DISC. E-DIS trial provides valuable data to support shared decision-making between physicians and patients regarding CT-CONT/DISC.

BACKGROUND: There is no consensual treatment of locally advanced or metastatic chordomas. PATIENTS AND METHODS: We conducted a multicenter, open-label, uncontrolled phase II trial of sorafenib (800 mg/day). The primary end point was the 9-month progression-free rate according to RECIST 1.1. All patients had documented progressive disease at the time of study entry. RESULTS: Twenty-seven patients were enrolled between May 2011 and January 2014. The median age was 64 (range, 30-86) years. There were 17 men and 10 women. Twelve patients had been previously treated with chemotherapy and molecularly targeted agents. The maximum toxicity grade per patient was grade 3 in 21 cases (77.8%) and grade 4 in 4 cases (14.8%). Sorafenib provided an intent-to-treat best objective response of 1/27 [3.7%; 95% confidence interval (CI) 0.1% to 19.0%], a 9-month progression-free rate of 73.0% (95% CI 46.1-88.0) and a 12-month overall survival rate of 86.5% (95% CI 55.8-96.5). Survival curves were similar in pretreated and not pretreated patients. DISCUSSION: Additional clinical trials further exploring sorafenib as a treatment of locally advanced or metastatic chordomas are warranted.

BACKGROUND: Preclinical findings suggest that imatinib mesylate (IM) and metronomic cyclophosphamide (MC) combination provides synergistic antiangiogenic activity on both pericytes and endothelial cells. METHODS: We have designed a 3+3 dose-escalating phase I trial with a fixed dose of MC (50 mg two times daily) plus IM (400 mg per day; 300 and 400 mg two times daily). Enrolled patients had IM- and sutininib-refractory advanced gastrointestinal stromal tumours (GIST) (n=17), chordoma (n=7) and mucosal melanoma (n=2). Dose-limiting toxicities were monitored for the first 6 weeks. Progression-free survival (PFS) and response assessment are based on RECIST 1.0 guidelines. Pharmacokinetics of IM were measured before and after exposure to MC. RESULTS: No dose-limiting toxicity was observed. Fourteen patients of the expanded cohort received 400 mg two times daily of IM with MC. Apart from a case of possibly related acute leukaemia occurring after 4 years of treatment, we did not see unexpected toxicity. No drug-drug pharmacokinetic interaction was observed. There was no objective response. We have observed long-lasting stable disease in chordoma patients (median PFS=10.2 months; range, 4.2-18+) and short-term stable disease in heavily GIST pretreated patients (median PFS=2.3 months; range, 2.1-6.6). CONCLUSION: This combination is feasible and may warrant further exploration in refractory GIST or chordoma patients.

PURPOSE: Impairment of cognitive function, a common complaint in patients receiving chemotherapy, is usually measured through neuropsychological tests. Patient self-evaluation of cognitive difficulties is an important complement to those tests. The Functional Assessment of Cancer Therapy-Cognitive Function (FACT-Cog) is a self-report questionnaire with potential to be used in standard clinical practice as a tool for evaluating patient's cognitive function before, during, and after chemotherapy. The purpose of our study was to conduct linguistic validation of the French version of the FACT-Cog. METHODS: Both qualitative and quantitative methods were used in this study. After undergoing a rigorous translation methodology, the French FACT-Cog version was pretested in France with 35 cancer patients undergoing chemotherapy treatment. Interviews were conducted with all patients to ascertain their understanding of each item. The validation of the final version was conducted among 63 cancer patients, and sociodemographic information was collected as well as brief measure of cognitive function and depression score. RESULTS: Patient comments obtained through the cognitive debriefing interviews indicated that patients understand the French FACT-Cog items as they are intended and that the measure is culturally appropriate. Internal consistency reliability of the subscales, evaluated using Cronbach's coefficient alpha, was high for all four subscales: Perceived Cognitive Impairments = 0.93, Impact On QOL = 0.85, Comments From Others = 0.70, and Perceived Cognitive Abilities = 0.89. All item-total correlations for each subscale were greater than 0.20, and most were greater than 0.50. CONCLUSIONS: Results from this study effectively demonstrate that the French FACT-Cog is a reliable instrument for the self-reporting of cognitive abilities in patients undergoing chemotherapy.

BACKGROUND: To evaluate the antitumour activity and safety of metronomic cyclophosphamide vs megestrol acetate in progressive and advanced cancer patients having exhausted all effective therapies under standard care. METHODS: Patients were randomly assigned to receive orally metronomic cyclophosphamide (50 mg b.i.d) or megestrol acetate (160 mg only daily) until intolerance or progression (RECIST 1.0). The primary efficacy end point was a 2-month progression-free rate (PFR(2m)). According to Optimal Simon's design and the following assumptions, namely, P0=5%, P1=20%, alpha=beta=10%, the treatment is considered as effective if atleast 5 out of 44 patients achieved PFR(2m). RESULTS: Between September 2006 and January 2009, 88 patients were enrolled. Two patients experienced grade 3-4 toxicities in each arm (4%). One toxic death occurred in the megestrol acetate arm as a consequence of thrombosis. The metronomic cyclophosphamide arm reached the predefined level of efficacy with a PFR(2m) rate of 9 out of 44 and a PFR(4m) rate of 5 out of 44. The MA arm failed to achieve the level of efficacy with a PFR(2m) of 4 out of 44 and a PFR(4m) of 1 out of 44. The median overall survival was 195 and 144 days in the metronomic cyclophosphamide arm and megestrol acetate arm, respectively. CONCLUSION: Metronomic cyclophosphamide is well tolerated and provides stable disease in such vulnerable and poor-prognosis cancer patients. This regimen warrants further evaluations.

The optimal management of adult soft-tissue sarcomas is not clearly established. To assess prognostic factors and survival, the experience of 45 recent successive cases was reviewed. Data were collected from a retrospective database (1993-2005) and statistically analyzed. Rhabdomyosarcomas were excluded. The mean age was 50.1 years; there were 24 men and 21 women. The main histological subtypes were undifferentiated sarcoma (14) and angiosarcoma (10); 21 tumours were grade 3 (46%). The most frequent primary sites were neck muscles (15, 33%) and scalp (11, 24%). At presentation, 5 (20%) cases with lymph-node involvement and another 11 cases (24%) with distant metastasis were observed. The treatment was with curative intent in 33 cases (73%). This entailed surgery, with adjuvant radiotherapy in 15 cases and adjuvant chemotherapy in 5 cases. The 5-year overall survival was 52% (+/-8%). In univariate analysis, the poor prognostic factors were high grade, initial metastasis or lymph nodes, absence of surgery, and number of surgical procedures. In multivariate analysis, two factors remained significant: grade (P=0.006) and absence of surgery (P=0.005). After taking into account grade and metastasis at presentation, quality of surgery has prognostic value. The primary aim of a multidisciplinary approach to these tumours must favour complete resection.

The clinical impact of surgical site infections (SSI) and postoperative pneumonia (PP) after head and neck cancer surgery has been assessed in the past, but little is known about their economic impact. The present study was designed to evaluate costs related to SSI and PP after head and neck cancer surgery with opening of mucosa. The incidence of SSI and PP was measured in a prospective cohort of 261 patients who had undergone head and neck cancer surgery. The additional direct medical costs related to these infections from the hospital perspective were determined based on postoperative length of stay. The mean direct hospital costs for patients with and without SSI or PP were compared. Of the 261 patients, 81 (31%), 21 (8%) and 13 (5%) developed SSI, PP or both, respectively. The additional lengths of stay attributable to SSI, PP or both were 16, 17 and 31 days, respectively, and additional direct medical costs related to these conditions were 17,000, 19,000 and 35,000 Euros. Nosocomial infections after head and neck cancer surgery significantly increase patients' length of stay and therefore generate additional direct medical costs. These results support the application of preventive interventions to reduce nosocomial infections in this setting.
