Protective effect of coffee consumption on all-cause mortality of French HIV-HCV co-infected patients.

BACKGROUND & AIMS: Coffee has anti-inflammatory and hepato-protective properties. In the general population, drinking ≥3cups of coffee/day has been associated with a 14% reduction in the risk of all-cause mortality. The aim of this study was to investigate the relationship between coffee consumption and the risk of all-cause mortality in patients co-infected with human immunodeficiency virus (HIV) and hepatitis C virus (HCV). METHODS: ANRS CO13 HEPAVIH is an ongoing French nationwide prospective cohort of patients co-infected with HIV-HCV collecting both medical and psychosocial/behavioural data (annual self-administered questionnaires). We used a Cox proportional hazards model to estimate the effect of elevated coffee consumption (≥3cups/day) at baseline on all-cause mortality during the cohort's five-year follow-up. RESULTS: Over a median [interquartile range] follow-up of 5.0 [3.9-5.9] years, 77 deaths occurred among 1,028 eligible patients (mortality rate 1.64/100 person-years; 95% confidence interval [CI] 1.31-2.05). Leading causes of death were HCV-related diseases (n=33, 43%), cancers unrelated to AIDS/HCV (n=9, 12%), and AIDS (n=8, 10%). At the first available visit, 26.6% of patients reported elevated coffee consumption. Elevated coffee consumption at baseline was associated with a 50% reduced risk of all-cause mortality (hazard ratio 0.5; CI 0.3-0.9; p=0.032), after adjustment for gender and psychosocial, behavioral and clinical time-varying factors. CONCLUSIONS: Drinking three or more cups of coffee per day halves all-cause mortality risk in patients co-infected with HIV-HCV. The benefits of coffee extracts and supplementing dietary intake with other anti-inflammatory compounds need to be evaluated in this population. LAY SUMMARY: Coffee has anti-inflammatory and hepato-protective properties but its effect on mortality risk has never been investigated in patients co-infected with human immunodeficiency virus (HIV) and hepatitis C virus (HCV). This study shows that elevated coffee consumption (≥3cups/day) halves all-cause mortality risk in patients co-infected with HIV-HCV. The benefits of coffee extracts and supplementing dietary intake with other anti-inflammatory compounds need to be evaluated in this population.

Outcomes of multimodal management for sinonasal squamous cell carcinoma.

BACKGROUND: Poor prognosis of sinonasal cancers (SNC) is usually due to the non-specific symptoms leading to late diagnosis with locally advanced disease. However, previous prognostic studies were often based on heterogeneous cohorts because of the scarcity of SNC. With squamous cell carcinoma being the main histological subgroup, the study aimed to perform a prognostic analysis on sinonasal squamous cell carcinoma (SNSCC) particularly, and to evaluate the oncological results of a multimodal therapy. METHODS: A retrospective review of 68 cases involving SNSCC treatment between 1998 and 2012 at Gustave Roussy Cancer Campus was performed. Clinical, pathological, and treatment characteristics were evaluated as prognostic markers for oncological outcomes. RESULTS: The 5-year overall survival (OS) and progression-free survival (PFS) rates were 58.1% and 52.6% respectively. Tumor downsizing under neoadjuvant chemotherapy (NACT) was observed in 82.5% of cases. The main pattern of recurrence was local with a 2- and 5-year rate of 37.3%. Decreased OS, PFS and local control were associated with involvement of the orbit, the soft tissue, and the suprastructure (p < 0.005). CONCLUSION: Prognosis of surgically treated SNSCC remains poor. Multimodal treatment combining NACT followed by wide resection requiring complex reconstruction and adjuvant radiation therapy seems to provide promising results.

Predictive and prognostic value of CT based radiomics signature in locally advanced head and neck cancers patients treated with concurrent chemoradiotherapy or bioradiotherapy and its added value to Human Papillomavirus status.

OBJECTIVES: To explore prognostic and predictive value of radiomics in patients with locally advanced head and neck squamous cell carcinomas (LAHNSCC) treated with concurrent chemoradiotherapy (CRT) or bioradiotherapy (BRT). MATERIALS AND METHODS: Data of 120 patients (CRT vs. BRT matched 2:1) were retrospectively analyzed. A total of 544 radiomics features of the primary tumor were extracted from radiotherapy planning computed tomography scans. Cox proportional hazards models were used to examine the association between survival and radiomics features with false discovery rate correction. The discriminatory performance was evaluated using receiver operating characteristic curve analysis. RESULTS: Multivariate analysis showed a 24-feature based signature significantly predicted for OS (HR=0.3, P=0.02) and progression-free survival (PFS) (HR=0.3, P=0.01). Combining the radiomics signature with p16 status showed a significant improvement of prognostic performance compared with p16 (AUC=0.78vs. AUC=0.64 at 5years, P=0.01) or radiomics signature (AUC=0.78vs. AUC=0.67, P=0.01) alone. When patients were stratified according to this combination, OS and PFS were significantly different according to the 4 sub-types (p16+ with low/high signature score; p16- with low/high signature score) (P<0.001). Patients with high signature score significantly benefited from CRT (vs. BRT) in terms of OS (P=0.004), while no benefit from CRT in patients with low signature score. CONCLUSION: Our analysis suggests an added value of radiomics features as prognostic and predictive biomarker in HNSCC treated with CRT/BRT. Moreover, the radiomics signature provided additional information to HPV/p16 status to further stratify patients. External validation of such findings is mandatory given the risk of overfitting.

High-Throughput Genomics and Clinical Outcome in Hard-to-Treat Advanced Cancers: Results of the MOSCATO 01 Trial.

High-throughput genomic analyses may improve outcomes in patients with advanced cancers. MOSCATO 01 is a prospective clinical trial evaluating the clinical benefit of this approach. Nucleic acids were extracted from fresh-frozen tumor biopsies and analyzed by array comparative genomic hybridization, next-generation sequencing, and RNA sequencing. The primary objective was to evaluate clinical benefit as measured by the percentage of patients presenting progression-free survival (PFS) on matched therapy (PFS2) 1.3-fold longer than the PFS on prior therapy (PFS1). A total of 1,035 adult patients were included, and a biopsy was performed in 948. An actionable molecular alteration was identified in 411 of 843 patients with a molecular portrait. A total of 199 patients were treated with a targeted therapy matched to a genomic alteration. The PFS2/PFS1 ratio was >1.3 in 33% of the patients (63/193). Objective responses were observed in 22 of 194 patients (11%; 95% CI, 7%-17%), and median overall survival was 11.9 months (95% CI, 9.5-14.3 months).Significance: This study suggests that high-throughput genomics could improve outcomes in a subset of patients with hard-to-treat cancers. Although these results are encouraging, only 7% of the successfully screened patients benefited from this approach. Randomized trials are needed to validate this hypothesis and to quantify the magnitude of benefit. Expanding drug access could increase the percentage of patients who benefit.

Factors associated with success of image-guided tumour biopsies: Results from a prospective molecular triage study (MOSCATO-01).

INTRODUCTION: MOSCATO-01 is a molecular triage trial based on on-purpose tumour biopsies to perform molecular portraits. We aimed at identifying factors associated with high tumour cellularity. MATERIAL AND METHODS: Tumour cellularity (percentage of tumour cells in samples defined at pathology) was evaluated according to patient characteristics, target lesion characteristics, operators' experience and biopsy approach. RESULTS: Among 460 patients enrolled between November, 2011 and March, 2014, 334 patients (73%) had an image-guided needle biopsy of the primary tumour (N = 38) or a metastatic lesion (N = 296). Biopsies were performed on liver (N = 127), lung (N = 72), lymph nodes (N = 71), bone (N = 11), or another tumour site (N = 53). Eighteen patients (5%) experienced a complication: pneumothorax in 10 patients treated medically, and haemorrhage in 8, requiring embolisation in 3 cases. Median tumour cellularity was 50% (interquartile range, 30-70%). The molecular analysis was successful in 291/334 cases (87%). On-going chemotherapy, tumour origin (primary versus metastatic), lesion size, tumour growth rate, presence of necrosis on imaging, standardised uptake value, and needle size were not statistically associated with cellularity. Compared to liver or lung biopsies, cellularity was significantly lower in bone and higher in other sites (P < 0.0001). Cellularity significantly increased with the number of collected samples (P < 0.0001) and was higher in contrast-enhanced ultrasound-guided biopsies (P < 0.02). In paired samples, cellularity in central samples was lower than in peripheral samples in 85, equal in 68 and higher in 89 of the cases. CONCLUSION: Image-guided biopsy is feasible and safe in cancer patients for molecular screening. Imaging modality, multiple sampling of the lesion, and the organ chosen for biopsy were associated with higher tumour cellularity.

Circulating Cell-Free Tumor DNA Analysis of 50 Genes by Next-Generation Sequencing in the Prospective MOSCATO Trial.

PURPOSE: Liquid biopsies based on circulating cell-free DNA (cfDNA) analysis are described as surrogate samples for molecular analysis. We evaluated the concordance between tumor DNA (tDNA) and cfDNA analysis on a large cohort of patients with advanced or metastatic solid tumor, eligible for phase I trial and with good performance status, enrolled in MOSCATO 01 trial (clinical trial NCT01566019). EXPERIMENTAL DESIGN: Blood samples were collected at inclusion and cfDNA was extracted from plasma for 334 patients. Hotspot mutations were screened using next-generation sequencing for 50 cancer genes. RESULTS: Among the 283 patients with tDNA-cfDNA pairs, 121 had mutation in both, 99 in tumor only, 5 in cfDNA only, and for 58 patients no mutation was detected, leading to a 55.0% estimated sensitivity [95% confidence interval (CI), 48.4%-61.6%] at the patient level. Among the 220 patients with mutations in tDNA, the sensitivity of cfDNA analysis was significantly linked to the number of metastatic sites, albumin level, tumor type, and number of lines of treatment. A sensitivity prediction score could be derived from clinical parameters. Sensitivity is 83% in patients with a high score (≥8). In addition, we analyzed cfDNA for 51 patients without available tissue sample. Mutations were detected for 22 patients, including 19 oncogenic variants and 8 actionable mutations. CONCLUSIONS: Detection of somatic mutations in cfDNA is feasible for prescreening phase I candidates with a satisfactory specificity; overall sensitivity can be improved by a sensitivity score allowing to select patients for whom cfDNA constitutes a reliable noninvasive surrogate to screen mutations.
