RESUMEN
PURPOSE: Post acute sequelae of SARS-CoV-2 infection are defined by persistence or re-occurrence of symptoms six to 12 weeks after SARS-CoV-2 infections. METHODS: Twice vaccinated hospital employees after mild to moderate post-vaccination SARS-CoV-2 infection completed a questionnaire on the incidence of general, respiratory, neuropsychiatric, dermatological and gastrointestinal symptoms, experienced during their acute infection and eight weeks after recovery. Post acute sequelae of SARS-CoV-2 infection were analysed in relation to socio-demographic-, health-, virus- and acute infection-related characteristics. RESULTS: 73 participants, 25 women and 48 men with a mean age of 40.9 years, with a post-vaccination SARS-CoV-2 infection completed the survey. Out of these 93 % reported at least one symptom at time of initial SARS-CoV-2 infection, 31.5 %, predominantly women, reported post acute sequelae at least eight weeks after the acute infection stage. Fatigue, dysgeusia and dysosmia, headache or difficulty concentrating and shortness of breath during acute infection, BMI> 25 and pre-existing pulmonary disorders were associated with post acute sequelae of SARS-CoV-2 infection. Participants with initially more than five symptoms were four times more likely to report post acute sequelae. CONCLUSION: It is suggested that the multiplicity of symptoms during acute SARS-CoV-2 infections increases the risk for post acute symptoms.

OBJECTIVE: We aimed to investigate whether (1) psychological and social indicators influence survival in patients diagnosed with cancer or haematologic malignancies when important biological aspects are controlled for, (2) psychological, social and biological indicators can be utilised to design one collated index for survival, usable in clinical practice to identify patients at risk of shorter survival and to improve personalised healthcare provision. METHODS: In this cross-sectional study, 2263 patients with cancer or haematologic malignancies participated. We analysed 15 biological, psychological and social indicators as risk factors for survival with a Cox proportional hazards model. Indicators significantly associated with survival were combined to compute models for the identification of patient groups with different risks of death. The training sample contained 1122 patients. Validation samples included the remaining 1141 patients, the total sample, as well as groups with different cancer entities. RESULTS: Five indicators were found to significantly impact survival: Cancer site (HR: 3.56), metastatic disease (HR: 1.88), symptoms of depression (HR: 1.34), female sex (HR: 0.73) and anaemia (HR: 0.48). Combining these indicators to a model, we developed the Cancer Survival Index, identifying three distinct groups of patients with estimated survival times of 47.2 months, 141 months and 198.2 months (p < 0.001). Post hoc analysis of the influence of depression on survival showed a mediating effect of the following four factors, related to both depression and survival: previous psychiatric conditions, employment status, metastatic disease and haemoglobin levels. CONCLUSIONS: Psychosocial and biological factors impact survival in various malignancies and can be utilised jointly to compute an index for estimating the survival of each patient individually-the Cancer Survival Index.

OBJECTIVES: The identification of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) antigen or RNA in respiratory specimens ≥14 days after administration of all recommended doses of authorized coronavirus disease 2019 (COVID-19) vaccines is defined as breakthrough infection. In the present investigation, mRNA and vector-based SARS-CoV-2 vaccines were analysed with respect to postvaccination infections in vaccinated hospital employees. METHODS: A total of 8553 staff members were vaccinated with BNT162b2 (47%) or ChAdOx1-S (53%) between January and May 2021. In a retrospective observational cohort study, incidence of SARS-CoV-2 postvaccination infections was analysed in relation to demographic data, viral load, virus variants, vaccine brand and vaccination status at time of positive PCR test (fully vaccinated: ≥14 days since second dose; partially vaccinated: >21 days since first, but <14 days after second dose; insufficiently vaccinated: <22 days since first dose). RESULTS: Within the follow-up period, ending on 31 July 2021, person-time at risk-adjusted monthly rates for SARS-CoV-2 postvaccination infections were 0.18% (BNT162b2) and 0.57% (ChAdOx1-S) for insufficiently vaccinated, 0.34% (BNT162b2) and 0.32% (ChAdOx1-S) for partially vaccinated and 0.06% (BNT162b2) and 0.04% (ChAdOx1-S) for fully vaccinated participants. The two vaccine types did not differ with respect to hazard ratios for any of the respective postvaccination infection types. No cases of COVID-19-related hospitalizations or deaths were reported. Genotyping of positive PCR specimens revealed 42 variants of concern: B.1.1.7 (Alpha variant; n = 34); B.1.351 (Beta variant; n = 2), B.1.617.2 (Delta variant; n = 6). CONCLUSIONS: BNT162b2 and ChAdOx1-S are both effective in preventing breakthrough infections; however, it seems important, that all recommended vaccine doses are administered.

Background: Inflammation-based scores are widely tested in cancer and have been evaluated in cardiovascular diseases including heart failure. Objectives: We investigated the impact of established inflammation-based scores on disease severity and survival in patients with stable heart failure with reduced ejection fraction (HFrEF) paralleling results to an intra-institutional cohort of treatment naïve cancer patients. Methods: HFrEF and cancer patients were prospectively enrolled. The neutrophil-to-lymphocyte-ratio (NLR), the monocyte-to-lymphocyte-ratio (MLR), the platelet-to-lymphocyte-ratio (PLR), and the prognostic nutritional index (PNI) at index day were calculated. Association of scores with disease severity and impact on overall survival was determined. Interaction analysis was performed for the different populations. Results: Between 2011 and 2017, a total of 818 patients (443 HFrEF and 375 cancer patients) were enrolled. In HFrEF, there was a strong association between all scores and disease severity reflected by NT-proBNP and NYHA class (p ≤ 0.001 for all). In oncologic patients, association with tumor stage was significant for the PNI only (p = 0.035). In both disease entities, all scores were associated with all-cause mortality (p ≤ 0.014 for all scores). Kaplan-Meier analysis confirmed the discriminatory power of all scores in the HFrEF and the oncologic study population, respectively (log-rank p ≤ 0.026 for all scores). A significant interaction with disease (HFrEF vs. cancer) was observed for PNI (p interaction = 0.013) or PLR (p interaction = 0.005), respectively, with higher increase in risk per inflammatory score increment for HFrEF. Conclusion: In crude models, the inflammatory scores NLR, MLR, PLR, and PNI are associated with severity of disease in HFrEF and with survival in HFrEF similarly to cancer patients. For PNI and PLR, the association with increase in risk per increment was even stronger in HFrEF than in malignant disease.
RESUMEN
AIMS: Cancer patients suffer from impaired cardiovascular function. Elevated resting heart rate (RHR) has been identified as a marker for increased long-term mortality in cancer patients prior to the receipt of anticancer treatment. We aimed to establish whether RHR is associated with survival in treatment-naïve cancer patients. METHODS AND RESULTS: This prospective study enrolled 548 unselected treatment-naïve cancer patients between 2011 and 2013. The median age of the cohort was 62 years; 40.9% were male and 32.7% had metastatic disease. Median RHR was 72 b.p.m. Most patients were in sinus rhythm (n = 507, 92.5%). Clinical heart failure was noted in 37 (6.8%) patients. RHR was not related to cancer stage (P = 0.504). Patients in the highest RHR tertile had higher levels of high-sensitivity troponin (P = 0.003) and N-terminal pro-B-type natriuretic peptide (P = 0.039). During a median follow-up of 25 months (interquartile range: 16-32 months; range: 0-40 months), 185 (33.8%) patients died from any cause [1-year-mortality: 17%, 95% confidence interval (CI) 13-20%]. In univariate survival analysis, RHR predicted all-cause mortality [crude hazard ratio (HR) for a 5 b.p.m. increase in RHR: 1.09, 95% CI 1.04-1.15; P < 0.001], and remained significantly associated with outcome after adjustment for age, gender, tumour entity, tumour stage, cardiac status and haemoglobin (adjusted HR for a 5 b.p.m. increase in RHR: 1.10, 95% CI 1.04-1.16; P < 0.001). There was no significant impact of metastatic/non-metastatic disease state on the predictive value of RHR (P = 0.433 for interaction). In subgroup analyses, the strongest associations for RHR with mortality were observed in lung (crude HR 1.14; P = 0.007) and gastrointestinal (crude HR 1.31; P < 0.001) cancer. CONCLUSIONS: Treatment-naïve cancer patients with higher RHRs display higher levels of cardiovascular biomarkers. RHR was independently associated with all-cause mortality, especially in lung and gastrointestinal cancers. Elevated RHR and cardiovascular biomarkers may represent early signs of incipient cardiac dysfunction.

BACKGROUND: New chemotherapy regimens for the treatment of metastatic pancreatic cancer have changed the therapy paradigm. We aimed to assess their impact on the treatment landscape and clinical outcome at our academic institution. METHODS: In this single institutional posthoc registry analysis, we assessed characteristics and survival rates from all patients with locally advanced and metastatic pancreatic cancer who started a systemic treatment between 01/2011 and 12/2017. Survival analyses were performed by Kaplan-Meier and Cox proportional hazards model. RESULTS: A total of 301 patients started a systemic treatment in the observation period. In the first line treatment, we observed a shift from the four different main regimens (gemcitabine/nab-paclitaxel, modified FOLFIRINOX, gemcitabine/oxaliplatin +/- erlotinib or gemcitabine alone) to gemcitabine/nab-paclitaxel and modified FOLFIRINOX that add up to more than 80% of administered first line treatments in each of the time cohorts (2011-2013 vs. 2014-2017). The rate for first line modified FOLFIRINOX treatment was balanced between the two groups (19% and 15%). Median overall survival differed significantly between the two time cohorts (8.89 versus 11.9 months, p = 0.035). Survival rates for different first to second line treatment sequences (modified FOLFIRINOX to gemcitabine/nab-paclitaxel, gemcitabine/nab-paclitaxel to fluoropyrimidines plus nanoliposomal irinotecan, or gemcitabine/nab-paclitaxel to fluoropyrimidines plus oxaliplatin) were not significantly different and median overall survival ranged from 14.27 to 15.64 months. CONCLUSION: Our study provides real-world evidence for the effectiveness of the new chemotherapy regimens and underscores the importance of the choice of the front-line regimen when considering different sequencing strategies.
RESUMEN
Background: Nasopharyngeal carcinoma (NPC) is endemic in East Asia but rare in the western world. Programmed death ligand 1 (PD-L1) expression on NPC correlates with clinical outcomes. However, data for Caucasian NPC patients are missing. Thus, we performed this retrospective analysis for investigating the potential association of immune checkpoint protein expression with outcome parameters in Caucasian NPC patients. Methods: Fifty-five patients with NPC treated between 1993 and 2018 at the Medical University of Vienna were identified. After the exclusion of Asian patients, data on baseline demographic, tumor stage, overall survival (OS), and disease-free survival (DFS) of 30 patients were analyzed. Their tumor samples were stained and scored (low vs. high) for PD-L1, programmed death receptor 1 (PD-1), lymphocyte activating gene 3 (LAG3), and cluster of differentiation 8 (CD8) antibodies. Statistical analysis was performed with Kaplan-Meier plots and log-rank test. Estimated hazard ratios of dichotomized analysis were calculated, together with 95% confidence intervals and p-values of Wald tests. Results: PD-L1 expression was ≥50% in 6 (20%) patients, whereas 19 (63%) had ≥1% expression and 5 (17%) tumor samples were PD-L1-negative. While sex and age had no impact on DFS or OS, <50% PD-L1 expression on tumor cells (TC) was associated with a significantly longer OS (log rank test p = 0.037; HR 0.275; 95% CI 0.073-1.03). There was no influence on DFS (log rank test p = 0.34; HR 0.599; 95% CI 0.208-1.728). However, <10% PD-L1 expression on tumor infiltrating lymphocytes (TILs) was correlated with a worse DFS (log rank test p = 0.0057; HR 4.06; 95% CI 1.389-11.868). LAG3 expression or the number of TILs did not play any prognostic role in our population. Conclusion: The PD-L1 expression rate on Caucasians was comparable to that in Asian patients. Although these results have to be interpreted with caution due to the limited number of Caucasian patients available, our data suggest that ≥50% PD-L1 expression on TC is associated with a poor outcome, while ≥10% PD-L1 expression on TILs is correlated with improved DFS. A prospective biomarker analysis of a predefined Caucasian NPC subpopulation would be desirable in future trials.
RESUMEN
AIM: GDF-15 is an established cardiovascular risk marker but is equally implicated in tumour biology. Elevated levels of GDF-15 have indeed been observed in distinct tumour entities. This study aimed to explore the relation of GDF-15 to other cardiac biomarkers and the general association of GDF-15 on prognosis in an unselected cohort of treatment-naïve cancer patients. METHODS: We prospectively enrolled 555 consecutive patients at time of diagnosis of malignant disease prior receiving anticancer therapy. Plasma GDF-15 concentrations were determined alongside other cardiac and routine laboratory markers. All-cause mortality was defined as primary endpoint. RESULTS: GDF-15 levels were 338 ng/L (IQR:205-534) for the total cohort, and values were comparable for different tumour entities except breast cancer. Metastatic disease was characterized by higher plasma GDF-15 [435 ng/L (IQR:279-614) vs 266 ng/L (IQR:175-427), P < .001]. GDF-15 correlated positively with inflammatory status reflected by CRP, SAA and IL-6 [r = .31, P < .001, r = .23, P < .001 and r = .14, P = .002] and cardiac biomarkers as NT-proBNP, hsTnT, MR-proADM and CT-proET-1 [r = .46; r = .46; r = .59 and r = .50; P < .001 for all]. GDF-15 was significantly associated with all-cause mortality after multivariate adjustment [adj.HR for ln(GDF-15) 1.78, 95%CI:1.47-2.16, P < .001]. There was a significant interaction between solid and haematological malignancies with loss of association of GDF-15 with outcome in myelodysplastic and myeloproliferative disease. CONCLUSIONS: Elevated plasma GDF-15 is associated with progressing disease severity and poor prognosis in solid tumours of treatment-naïve cancer patients. GDF-15 increase is accompanied by worsening systemic inflammation and a subclinical functional impairment of different organs including the heart. GDF-15 represents a promising target for our pathophysiologic understanding in cardio-oncology linking conditions of both cardiac and neoplastic disease.

OBJECTIVES: Patients with head and neck squamous cell carcinoma (HNSCC) can experience severe symptom burden and/or difficulty swallowing, leading to problems with treatment adherence/administration. In LUX-Head and Neck 1 (LH&N1; NCT01345682), second-line afatinib improved progression-free survival (PFS) versus methotrexate in patients with recurrent/metastatic HNSCC. We report adherence and safety across pre-specified and additional subgroups potentially linked to afatinib PFS benefit in LH&N1 (p16 status, smoking history), and afatinib adherence, safety and efficacy by administration (oral versus feeding tube; post-hoc analysis). METHODS: Patients were randomized (2:1) to afatinib (40â¯mg/day) or intravenous methotrexate (40â¯mg/m2/week). RESULTS: Among 320 afatinib-treated and 160 methotrexate-treated patients, 83-92% and 76-92% (of patients with data available) across all subgroups took ≥80% of treatment. Across p16 status and smoking history subgroups, the most common treatment-related adverse events (AEs) were diarrhea (70-91%), rash/acne (72-84%), stomatitis (34-73%) with afatinib; and included stomatitis (39-100%), fatigue (22-50%), nausea (19-36%) with methotrexate. Dose reduction decreased AE incidence/severity. Baseline characteristics were generally similar between oral/feeding tube (nâ¯=â¯276/nâ¯=â¯46) groups. 89%/89% (of patients with data available) took ≥80% of assigned afatinib. Median PFS was 2.6 versus 2.7â¯months (hazard ratio: 0.997; 95% confidence interval: 0.72-1.38). The most common afatinib-related AEs were: rash/acne (74% versus 74%), diarrhea (73% versus 65%), stomatitis (40% versus 30%). CONCLUSION: Subgroup analyses of LH&N1 demonstrate that afatinib has predictable and manageable safety across patient subgroups, with high treatment adherence, and is effective via oral and feeding tube administration.

The transmembrane zink-metalloendopeptidase neprilysin (NEP) is implicated in cardiovascular disease but also tumor biology. The aim of the study was to investigate the relationship of circulating NEP (cNEP) levels with established cardiovascular biomarkers and its effect on overall survival in an unselected cohort of treatment-naïve cancer patients. 555 consecutive cancer patients prior anticancer therapy were enrolled prospectively. NEP levels were determined alongside routine laboratory parameters, established cardiac biomarkers, i.e. NT-proBNP, hsTnT, MR-proANP, MR-proADM, CT-proET-1 and Copeptin, and inflammatory parameters, i.e. CRP, IL-6 and SAA, in venous plasma samples. All-cause mortality was the primary endpoint. cNEP levels of 276 pg/ml (IQR: 0-5981) displayed a weak inverse correlation with age [r = -0.12, p = 0.023] and inflammatory status [r = -0.14, p = 0.007 CRP; r = -0.20, p < 0.001 IL-6 and r = -0.18, p < 0.001 SAA]. cNEP was comparable between different tumor entities and stages and not related to functional parameters of other organ systems as kidney, liver or especially the heart. Moreover, cNEP was not associated with overall survival in the total cohort [adj.HR for ln (cNEP) 1.00, 95% CI: 0.94-1.06, p = 0.887] but in myelodysplatic malignancies [adj.HR for ln (cNEP) 1.27, 95% CI: 1.01-1.61, p = 0.044]. In conclusion, cNEP lacks association with outcome but for myelodysplastic disease. cNEP shows no correlation with established cardiovascular biomarkers related to prognosis, thereby holding a limited potential as a biomarker in cardio-oncology.

OBJECTIVES: This retrospective study performed a comprehensive analysis of the usage of intra-arterial chemotherapy (iaCh) for locally recurrent UICC stage IV oral squamous cell carcinoma (OSCC) over two decades at the Department of Cranio-Maxillofacial and Oral Surgery at the University Hospital Vienna to assess the utility of its future use. METHODS: Between 1994 and 2014, iaCh was indicated in 48 OSCC cases. In these, the two most frequent iaCh schemes, cisplatin/5-fluorouracil (Cis/5-FU) and methotrexate/bleomycin (MTX/Bleo), were chosen for further analysis. The effect on survival of two distinct intra-arterial protocols and their covariates were analyzed with the Kaplan-Meier method as well as univariate and multivariate Cox proportional hazard regression models. RESULTS: The mean follow-up period was 29.91 months. The two intra-arterial chemotherapy groups did not differ significantly in sample size, demographic data or therapeutic covariates. The Cis/5-FU iaCh regimen was associated with significantly better overall survival (median OS 2.6 years vs. 1.3 years; p=0.002) and had a beneficial effect on survival (HR=3.62, p=0.015). Side effects occurred at a frequency similar to that described in the literature for intravenous chemotherapy (ivCh). CONCLUSIONS: These results suggest a preference for administering Cis/5-FU for iaCh. Nevertheless, due to economic considerations in healthcare expenditures, there is no future for iaCh in the treatment of head and neck carcinomas because ivCh is known to be equivalent.

Three weekly high-dose chemotherapy regimens in combination with weekly cetuximab are the treatment of choice for patients with recurrent/metastatic (R/M) head and neck squamous cell carcinoma (SCCHN), although the majority of patients suffer from severe side effects. Thus, we investigated the efficacy and safety of an alternative, more convenient and less toxic biweekly modified cisplatin, docetaxel plus cetuximab (TPEx) regimen in this retrospective analysis. Thirty-eight patients receiving off-protocol cisplatin (50 mg/m2) in combination with docetaxel (50 mg/m2) plus cetuximab (500 mg/m2) every other week were included. Data collection included baseline demographic, response rate (ORR) and toxicity data as well as disease control rate, overall survival (OS) and progression-free survival (PFS). The median age was 60 years, and the majority of patients suffered from oral cavity carcinomas (44.7%) followed by oropharyngeal (28.9%) and laryngeal (17.9%) carcinomas. The ORR was 50%, and four (10.5%) patients achieved a complete response, while 15 (39.5%) patients had a partial response. The OS and PFS were 10.8 months (95% CI 6.7-14.2) and 6.3 months (95% CI 5.7-6.8), respectively. The one-year survival rate was 44.7%. The therapy was well tolerated, and the most common grade 3/4 adverse events were myelosuppression (13.2%), hypomagnesaemia (23.7%) and acne-like rash (13.1%). In conclusion, modified biweekly TPEx is of comparable efficacy with conventional TPEx and represents a well-tolerated regimen in R/M SCCHN patients. Further evaluation of this protocol in prospective clinical trials is warranted.

BACKGROUND: Nutritional screening procedures followed by regular nutrition monitoring for oncological outpatients are no standard practice in many European hospital wards and outpatient settings. As a result, early signs of malnutrition are missed and nutritional treatment is initiated when patients have already experienced severe weight loss. OBJECTIVE: We report on a novel clinical decision support system (CDSS) for the global assessment and nutritional triage of the nutritional condition of oncology outpatients. The system combines clinical and laboratory data collected in the clinical setting with patient-generated data from a smartphone application for monitoring the patients' nutritional status. Our objective is to assess the feasibility of a CDSS that combines the aforementioned data sources and describe its integration into a hospital information system. Furthermore, we collected patients' opinions on the value of the system, and whether they would regard the system as a useful aid in coping with their condition. MATERIALS AND METHODS: The system implements the Patient-Generated Subjective Global Assessment (PG-SGA) to monitor nutritional status in the outpatient setting. A smartphone application is used to collect patient-generated data by performing weekly mini-surveys on patients concerning their eating habits, weight, and overall well-being. Data are uploaded on completion of each mini-survey and stored on a secure server at the Medical University of Vienna (MUV). The data are then combined with relevant clinical information from the Vienna General Hospital (VGH) information system. The knowledge base for the CDSS is implemented in medical logic modules (MLMs) using Arden Syntax. A three-month pilot clinical trial was performed to test the feasibility of the system. Qualitative questionnaires were used to obtain the patients' opinions on the usability and personal value of the system during the four-week test period. RESULTS: We used the existing separation between the scientific and clinical data domains in the secured network environment (SNE) at the MUV and VGH to our advantage by importing, storing, and processing both patient-generated and routine data in the scientific data domain. To limit exposure to the SNE, patient-generated data stored outside the SNE were imported to the scientific domain once a day. The CDSS created for nutritional assessment and triage comprised ten MLMs, each including either a sub-assessment or the final results of the PG-SGA. Finally, an interface created for the hospital information system showed the results directly in clinical routine. In all 22 patients completed the clinical study. The results of the questionnaires showed that 91% of the patients were generally happy with the usability of the system, 91% believed that the application was of additional value in detecting cancer-related malnutrition, and 82% found it helpful as a long-term monitoring tool. DISCUSSION AND CONCLUSION: Despite strict protection of the clinical data domain, a CDSS employing patient-generated data can be integrated into clinical routine. The CDSS discussed in this report combined the information entered into a smartphone application with clinical data in order to inform the physician of a patient's nutritional status and thus permit suitable and timely intervention. The initial results show that the smartphone application was well accepted by patients, who considered it useful, but not many oncological outpatients were willing to participate in the clinical study because they did not possess an Android phone or lacked smartphone expertise. Furthermore, the results indicate that patient-generated data could be employed to augment clinical data and calculate metrics such as the PG-SGA without excessive effort by using a secure intermediate location as the locus of data storage and processing.

Nevertheless, due to economic considerations in healthcare expenditures, there is no future for iaCh in the treatment of head and neck carcinomas because ivCh is known to be equivalent.

BACKGROUND: Routinely tested liver biomarkers as alanine aminotransferase (ALT), aspartate aminotransferase (AST), γ-glutamyltransferase (GGT), butyryl-cholinesterase (BChE), albumin and bilirubin are altered in distinct malignancies and hepatic metastases. This study aimed to investigate whether all liver parameters have the ability to predict long-term mortality in treatment naïve cancer patients but without a malignant hepatic involvement. METHODS: We prospectively enrolled 555 consecutive patients with primary diagnosis of cancer without prior anticancer therapy. BChE, albumin, AST, ALT, GGT and bilirubin as well as the inflammatory makers C-reactive protein (CRP), serum amyloid A (SAA) and interleukin-6 (IL-6) were determined. All-cause mortality was defined as primary endpoint. RESULTS: During a median follow-up of 25 (IQR16-31) months 186 (34%) patients died. All liver parameters were significantly associated with all-cause mortality (p < 0.001 for all). However, for patients without a malignant primary or secondary hepatic involvement (82%) only the functional parameters BChE and albumin remained significantly associated with the primary endpoint (crude HR per 1-IQR increase 0.61, 95%CI:0.49-0.77; p < 0.001 for BChE and 0.58, 95%CI:0.47-0.70; p < 0.001 for albumin). This e ect was persistent after multivariate adjustment (adj.HR per 1-IQR increase 0.65, 95%CI:0.50-0.86; p = 0.002 for BChE and 0.63, 95%CI:0.50-0.79; p < 0.001 for albumin). BChE and albumin correlated inversely with CRP (r = -0.21, p < 0.001 and r = -0.36, p < 0.001), SAA (r = -0.19, p < 0.001 and r = -0.33, p < 0.001) and IL-6 (r = -0.13, p = 0.009 and r = -0.17, p = 0.001). CONCLUSIONS: Decreased serum BChE and albumin levels are associated with increased all-cause mortality in treatment-naïve cancer patients without a manifest malignant hepatic involvement irrespective of tumor entity or stage. This association may reflect progressing systemic inflammation and metabolic derangement with subclinical involvement of the liver.
RESUMEN
OBJECTIVE: This phase 2 estimation study evaluated docetaxel/cisplatin with/without panitumumab, an anti-epidermal growth factor receptor monoclonal antibody, as first-line therapy for recurrent/metastatic squamous cell carcinoma of the head and neck (SCCHN). PATIENTS AND METHODS: Randomized patients received docetaxel/cisplatin (75mg/m(2) each) with/without panitumumab (9mg/kg) in 21-day cycles. Patients randomized to panitumumab+chemotherapy could continue panitumumab monotherapy after completing six chemotherapy cycles without progression; patients randomized to chemotherapy alone could receive second-line panitumumab after progression. Progression-free survival (PFS) was the primary endpoint. Secondary endpoints included overall survival (OS), overall response rate (ORR), time to response (TTR), duration of response (DOR), and safety. A protocol amendment limited enrollment to patients <70years owing to excess toxicity in older patients and added mandatory pegfilgrastim/filgrastim support. Outcomes were also analyzed by human papillomavirus status. RESULTS: 103 of the 113 enrolled patients were evaluable and randomized to receive ⩾1 dose of first-line treatment. Median PFS for panitumumab+chemotherapy was 6.9 (95% CI=4.7-8.3) months versus 5.5 (95% CI=4.1-6.8) months for chemotherapy alone (hazard ratio [HR]=0.629; 95% CI=0.395-1.002; P=0.048). ORR for panitumumab+chemotherapy was 44% (95% CI=31-58%) versus 37% (95% CI=24-51%) for chemotherapy alone (odds ratio [OR]=1.37; 95% CI=0.57-3.33). Median OS for panitumumab+chemotherapy was 12.9 (95% CI=9.4-18.5) months versus 13.8 (95% CI=11.8-22.9) months for chemotherapy alone (HR=1.103; 95% CI=0.709-1.717). Median TTR for panitumumab+chemotherapy treatment was 6.9weeks versus 11.0weeks for chemotherapy alone. Median DOR was 8.0 (95% CI=5.7-11.1) months with panitumumab+chemotherapy versus 5.1 (95% CI=4.4-7.2) months with chemotherapy alone. Grade 3/4 adverse event incidence was 73% with panitumumab+chemotherapy versus 56% with chemotherapy alone. 41% and 55% of patients in the panitumumab+chemotherapy and chemotherapy-alone arms, respectively, received panitumumab monotherapy. CONCLUSION: The addition of panitumumab to docetaxel/cisplatin may improve PFS in recurrent/metastatic SCCHN and has the potential to improve outcomes in these fully, or mostly, active patients.

For patients with recurrent/metastatic (R/M) head and neck squamous cell carcinoma (SCCHN) limited therapeutic options exist. Only a subset of patients is suitable for combination chemotherapy regimens. Biweekly docetaxel plus cetuximab might be an alternative option. Thus, we performed this retrospective analysis in unselected patients in order to investigate the efficacy and safety of this regimen. Thirty-one patients receiving off protocol docetaxel (50 mg/m(2)) plus cetuximab (500 mg/m(2)) biweekly were included. Data collection included baseline demographic, response rate (ORR), disease control rate (DCR), overall survival (OS), progression free survival (PFS) as well as toxicity. OS and PFS were 8.3 months (95% CI 4.8-11.8) and 4.0 months (95% CI 1.0-7.0), respectively. Three (9.7%) patients achieved a complete response and one patient (3.2%) a partial response. The DCR was 41.9% and we observed an ORR of 12.9%. The one-year survival rate was 25.8%. The therapy was well tolerated and the most common grade 3/4 adverse events were neutropenia (19.4%), hypomagnesaemia (12.9%) and acne-like rash (9.7%). Biweekly cetuximab/docetaxel is an effective regimen and well tolerated in R/M SCCHN patients not suitable for platinum doublet treatment. Further evaluation of this regimen in prospective clinical trials is warranted.

BACKGROUND: Advanced cholangiocellular carcinoma has a poor prognosis with limited therapeutic options. Nab-paclitaxel has recently been described to be beneficial in metastatic pancreatic cancer improving overall and progression free survival (PFS). The potential antitumor activity of nab-paclitaxel in cholangiocellular carcinoma is hitherto unknown. METHODS: We retrospectively analyzed an institutional cholangiocellular carcinoma registry to determine the potential biological activity of nab-paclitaxel in advanced intrahepatic cholangiocellular carcinoma. Disease control rate (DCR), PFS and overall survival (OS) upon nab-paclitaxel based treatment, after failure of platinum-containing first-line combination chemotherapy, was assessed. RESULTS: Twelve patients were identified. Five of 12 patients (42%) received nab-paclitaxel as second line, and 7 patients (56%) as third-line treatment. The objective DCR with nab-paclitaxel was 83% (10/12 patients). One patient had a complete remission (CR), two patients had a partial remission (PR) and 7 patients had stable disease (SD). Disease was rated progressive in two patients. In all 12 patients receiving nab-paclitaxel the median time to progression was 6 months (range, 2.1-19.5 months). Median OS after initiation of nab-paclitaxel treatment was 9 months (2.1-28.4 months). The median time of survival after diagnosis of advanced disease was 21.5 months, whereby 3 patients were alive at the date of censoring (04/01/2015). CONCLUSIONS: This is the first report suggesting substantial antitumor activity of nab-paclitaxel in advanced cholangiocellular carcinoma. In this small series, nab-paclitaxel based salvage chemotherapy appears to have a biological activity by controlling the disease and positively affecting survival. Randomized trials in this disease entity and subgroup of patients are urged.
RESUMEN
BACKGROUND: We aimed to determine the prognostic significance of pretreatment plasma fibrinigen in patients with oral and oropharyngeal squamous cell carcinoma (OOSCC). METHODS: A cohort of 183 patients with locally advanced OOSCC receiving preoperative chemoradiotherapy was retrospectively examined. Using ROC curve analysis, a pretreatment plasma fibrinogen cutoff value of 447mg/dL was determined. The primary endpoints were overall survival and recurrence-free survival. A secondary endpoint was to determine whether pretreatment plasma fibrinogen could predict treatment response to neoadjuvant chemoradiotherapy. Cox regression models and Kaplan-Meier curves were used for survival analyses. RESULTS: Seventy-one patients had an elevated pretreatment plasma fibrinogen (fibrinogen >447mg/dL). Patients with high fibrinogen showed significantly higher pathologic stages after neoadjuvant treatment than those with low fibrinogen (p = 0.037). In univariate analysis, elevated fibrinogen was associated with poor overall survival (p = 0.005) and recurrence-free survival (p = 0.008) Multivariate analysis revealed that elevated fibrinogen remained an independent risk factor for death (hazard ratio 1.78, 95% CI 1.09-2.90, p = 0.021) and relapse (hazard ratio 1.78, 95% CI 1.11-2.86, p = 0.016). CONCLUSION: Elevated pretreatment plasma fibrinogen is associated with lack of response to neoadjuvant chemoradiotherapy and reduced OS and RFS in patients with OOSCC. Thus, plasma fibrinogen may emerge as a novel prognostic indicator and a potential therapeutic target in OOSCC.

BACKGROUND: Combination chemotherapy regimens including fluoropyrimidines as well as albumin-bound paclitaxel have shown promising results in patients with metastatic pancreatic adenocarcinoma (mPC). Based on the recently described excellent therapeutic index of capecitabine plus nab-paclitaxel in metastatic breast cancer, the present phase II trial was initiated. METHODS: Patients with previously untreated mPC were treated with capecitabine (825 mg/m(2) orally bid on days 1-15) and nab-paclitaxel (125 mg/m(2) intravenously on days 1 and 8) every 3 weeks. In patients without clinically relevant adverse reactions after the 1st treatment course (≤ grade 2 toxicities according to NCI-CTC vs. 4.0, exuding alopecia and fatigue of any degree) and adequate bone marrow function, the nab-paclitaxel dose was escalated to 100 mg/m(2) on days 1, 8 and 15 of each cycle; this intra-individual dose escalation was maintained during subsequent treatment courses if tolerated. The primary endpoint was objective response rate (ORR) according to RECIST criteria, assessed by an independent radiological review committee with evaluation performed every 2 months. RESULTS: Between 12/2013 and 01/2015, 30 patients were entered in this monocentric academic phase II trial. All patients had an ECOG performance status of 0-1, 80% had liver metastases and 23% had biliary stents in place at time of study initiation. Median CA19-9 was 1,004 U/mL (0.9-100.000 U/mL). In all patients except 2, a dose escalation of nab-paclitaxel after the 1st treatment course could be accomplished. The most common grade 3 adverse events (AEs) included transient sensory neuropathy (23%), (afebrile) neutropenia (17%), hand-foot-syndrome (13%) and phototoxic skin reaction (10%). Among 29 RECIST-response assessable patients, the ORR was 41.4% and stable disease (SD) was noted in 34.5%, resulting in a disease control rate (DCR) of 76%. After a median follow-up duration of 10.3 months (range, 1.9-19.0 months), 13/30 patients (43.3%) are presently being alive. CONCLUSIONS: The combination of capecitabine + nab-paclitaxel at these doses and scheduling was well tolerated and showed substantial antitumor efficacy.
