What do patients and oncologists think about the evaluation and management of cancer-related anorexia-cachexia? The Quasar_SEOM study

Introduction Cancer patients often suffer from malnutrition and early detection and raising awareness of nutritional issues is crucial in this population. Methods The Spanish Oncology Society (SEOM) conducted the Quasar_SEOM study to investigate the current impact of the Anorexia–Cachexia Syndrome (ACS). The study employed questionnaires and the Delphi method to gather input from both cancer patients and oncologists on key issues related to early detection and treatment of ACS. A total of 134 patients and 34 medical oncologists were surveyed about their experiences with ACS. The Delphi methodology was used to evaluate oncologists' perspectives of ACS management, ultimately leading to a consensus on the most critical issues. Results Despite widespread acknowledgement of malnutrition in cancer as a significant issue by 94% of oncologists, the study revealed deficiencies in knowledge and protocol implementation. A mere 65% of physicians reported being trained to identify and treat these patients, with 53% failing to address ACS in a timely manner, 30% not monitoring weight, and 59% not adhering to any clinical guidelines. The lack of experience was identified as the primary hindrance to the use of orexigens in 18% of cases. Furthermore, patients reported concerns and a perception of inadequate attention to malnutrition-related issues from their physicians. Conclusion The results of this study point to a gap in the care of this syndrome and a need to improve education and follow-up of cancer patients with anorexia-cachexia (AU)

A Clinical-Genetic Risk Score for Predicting Cancer-Associated Venous Thromboembolism: A Development and Validation Study Involving Two Independent Prospective Cohorts.

PURPOSE: Venous thromboembolism (VTE) is a leading cause of death among patients with cancer. The Khorana score was developed for assessing the risk of VTE in outpatients with cancer receiving chemotherapy, but its accuracy in identifying patients at high risk has been questioned. The aim of this study was to develop and validate a clinical-genetic score that improves the assessment of VTE risk in oncology outpatients within 6 months of diagnosis. METHODS: The new score was developed using the data of 364 outpatients belonging to the Spanish ONCOTHROMB 12-01 population. In this cohort, clinical data associated with the risk of VTE were collected at the time of diagnosis, including the Khorana score. These patients were also genotyped for the 51 genetic variants known to be associated with VTE. Multivariate logistic regression was performed to determine the weight of each genetic and clinical variable in relation to VTE risk, allowing a clinical-genetic risk score (the ONCOTHROMB score) to be developed. The Khorana and the ONCOTHROMB scores were then compared via the area under the receiver operating characteristic curve (AUC), calibration, and the number of patients needed to treat. The new score was then validated in a study of 263 patients in the Vienna Cancer and Thrombosis Study population. RESULTS: Nine genetic variants, tumor site, TNM stage, and a body mass index of > 25 kg/m2 were found to be associated with VTE and were used to build the ONCOTHROMB score, which better predicted the overall risk of VTE than did the Khorana score (AUC, 0.781 v 0.580; P < .001). Similar AUC results were recorded in the validation study the Vienna Cancer and Thrombosis Study cohort involving patients with the same type of tumor (AUC for the ONCOTHROMB score v the Khorana score: 0.686 v 0.577; P < .001) and with all type of tumors (AUC for the ONCOTHROMB score v the Khorana score: 0.720 v 0.561; P < .0001). CONCLUSION: The ONCOTHROMB score for VTE risk in outpatients with cancer, which takes into account both clinical and genetic variables, better identifies patients who might benefit from primary thromboprophylaxis than does the Khorana score.

Evolution of RAS Mutations in Cell-Free DNA of Patients with Tissue RAS Wild-Type Metastatic Colorectal Cancer Receiving First-Line Treatment: The PERSEIDA Study.

The serial analysis of cell-free DNA (cfDNA) enables minimally invasive monitoring of tumor evolution, providing continuous genetic information. PERSEIDA was an observational, prospective study assessing the cfDNA RAS (KRAS/NRAS) mutational status evolution in first-line, metastatic CRC, RAS wild-type (according to baseline tumor tissue biopsy) patients. Plasma samples were collected before first-line treatment, after 20 ± 2 weeks, and at disease progression. One hundred and nineteen patients were included (102 received panitumumab and chemotherapy as first-line treatment-panitumumab subpopulation). Fifteen (12.6%) patients presented baseline cfDNA RAS mutations (n = 14 [13.7%], panitumumab subpopulation) (mutant allele fraction ≥0.02 for all results). No patients presented emergent mutations (cfDNA RAS mutations not present at baseline) at 20 weeks. At disease progression, 11 patients (n = 9; panitumumab subpopulation) presented emergent mutations (RAS conversion rate: 19.0% [11/58]; 17.7% [9/51], panitumumab subpopulation). In contrast, three (5.2%) patients presenting baseline cfDNA RAS mutations were RAS wild-type at disease progression. No significant associations were observed between overall response rate or progression-free survival and cfDNA RAS mutational status in the total panitumumab subpopulation. Although, in patients with left-sided tumors, a significantly longer progression-free survival was observed in cfDNA RAS wild-type patients compared to those presenting cfDNA RAS mutations at any time. Continuous evaluation of RAS mutations may provide valuable insights on tumor molecular dynamics that can help clinical practice.

Comparative analysis of capture methods for genomic profiling of circulating tumor cells in colorectal cancer.

The genomic profiling of circulating tumor cells (CTCs) in the bloodstream should provide clinically relevant information on therapeutic efficacy and help predict cancer survival. Here, we contrasted the genomic profiles of CTC pools recovered from metastatic colorectal cancer (mCRC) patients using different enrichment strategies (CellSearch, Parsortix, and FACS). Mutations inferred in the CTC pools differed depending on the enrichment strategy and, in all cases, represented a subset of the mutations detected in the matched primary tumor samples. However, the CTC pools from Parsortix, and in part, CellSearch, showed diversity estimates, mutational signatures, and drug-suitability scores remarkably close to those found in matching primary tumor samples. In addition, FACS CTC pools were enriched in apparent sequencing artifacts, leading to much higher genomic diversity estimates. Our results highlight the utility of CTCs to assess the genomic heterogeneity of individual tumors and help clinicians prioritize drugs in mCRC.

Venous Thromboembolism In Cancer Patients: "From Evidence to Care".

This article seeks to review the current status of treatment and prevention of venous thromboembolic disease (VTE) in cancer patients after the addition of direct oral anticoagulants (DOAC) to the therapeutic arsenal available. The suitability of DOAC use in complex clinical situations, poorly represented in clinical trials, is controversial and difficult for care activity, making the recommendations in clinical practice guidelines the focus of special attention in this area. Recently, several randomized trials have compared low molecular weight heparin (LMWH) to DOAC for the management of CAT. Potential drug interactions with DOACs or the increased risk of bleeding in intraluminal tumors require special precautions, as do metastatic or primary brain disease and comorbid conditions, such as renal or liver failure, which are not suitably represented in pivotal studies. Furthermore, few data are available for situations involving elevated bleeding risk, with thrombocytopenia levels below the inclusion criterion of clinical trials, or recurrence during active anticoagulant therapy. Similarly, it is less clear that patients and physicians accept the presumption that oral DOAC administration is more convenient than subcutaneous LMWH, particularly when drug absorption may be compromised. The non-inclusion or under-representation of patients at higher risk for complications with anticoagulation in randomized clinical trials, makes their use complex in certain situations in health care. This paper provides a practical review of current clinical guideline recommendations regarding LMWH and/ or DOAC to treat and prevent CAT, as well as the most controversial clinical conditions for their use.

Establishing an Expert Consensus on Key Indicators of the Quality of Life among Breast Cancer Survivors: A Modified Delphi Study.

(1) Background: The needs of cancer survivors are often not reflected in practice. One of the main barriers of the use of patient-reported outcomes is associated with data collection and the interpretation of patient-reported outcomes (PROs) due to a multitude of instruments and measuring approaches. The aim of the study was to establish an expert consensus on the relevance and key indicators of quality of life in the clinical practice of breast cancer survivors. (2) Methods: Potential indicators of the quality of life of breast cancer survivors were extracted from the established quality of life models, depicting survivors' perspectives. The specific domains and subdomains of quality of life were evaluated in a two-stage online Delphi process, including an international and multidisciplinary panel of experts. (3) Results: The first round of the Delphi process was completed by 57 and the second by 37 participants. A consensus was reached for the Physical and Psychological domains, and on eleven subdomains of quality of life. The results were further supported by the additional ranking of importance of the subdomains in the second round. (4) Conclusions: The current findings can serve to optimize the use of instruments and address the challenges related to data collection and interpretation as the facilitators of the adaption in routine practice.

Effect of aflibercept plus FOLFIRI and potential efficacy biomarkers in patients with metastatic colorectal cancer: the POLAF trial.

BACKGROUND: Aflibercept is an antiangiogenic drug against metastatic colorectal cancer (mCRC) combined with 5-fluorouracil/leucovorin/irinotecan (FOLFIRI); however, no antiangiogenic biomarker has yet been validated. We assessed aflibercept plus FOLFIRI, investigating the biomarker role of baseline vascular endothelial growth factor A (VEGF-A) and angiotensin-converting enzyme (ACE). METHODS: Phase II trial in oxaliplatin-treated mCRC patients who received aflibercept plus FOLFIRI. The reported 135 ng/mL ACE cut-off was used and ROC analysis was performed to assess the optimal VEGF-A cut-off for progression-free survival (PFS). Overall survival (OS), time to progression (TTP), time to treatment failure (TTF), overall response rate (ORR) and disease control rate (DCR) were also assessed. RESULTS: In total, 101 patients were followed for a median of 12 (6-17) months. The 1941 pg/mL VEGF-A was an optimal cut-off, with a longer median PFS when VEGF-A was <1941 versus ≥1941 pg/mL (9 versus 4 months). Patients with VEGF-A < 1941 pg/mL showed longer median OS (19 versus 8 months), TTP (9 versus 4 months) and TTF (8 versus 4 months), along with higher ORR (26% versus 9%) and DCR (81% versus 55%). No differences were identified according to ACE levels. CONCLUSIONS: This study supports aflibercept plus FOLFIRI benefits, suggesting VEGF-A as a potential biomarker to predict better outcomes.

Patients-centered SurvivorShIp care plan after Cancer treatments based on Big Data and Artificial Intelligence technologies (PERSIST): a multicenter study protocol to evaluate efficacy of digital tools supporting cancer survivors.

BACKGROUND: It is encouraging to see a substantial increase in individuals surviving cancer. Even more so since most of them will have a positive effect on society by returning to work. However, many cancer survivors have unmet needs, especially when it comes to improving their quality of life (QoL). Only few survivors are able to meet all of the recommendations regarding well-being and there is a body of evidence that cancer survivors' needs often remain neglected from health policy and national cancer control plans. This increases the impact of inequalities in cancer care and adds a dangerous component to it. The inequalities affect the individual survivor, their career, along with their relatives and society as a whole. The current study will evaluate the impact of the use of big data analytics and artificial intelligence on the self-efficacy of participants following intervention supported by digital tools. The secondary endpoints include evaluation of the impact of patient trajectories (from retrospective data) and patient gathered health data on prediction and improved intervention against possible secondary disease or negative outcomes (e.g. late toxicities, fatal events). METHODS/DESIGN: The study is designed as a single-case experimental prospective study where each individual serves as its own control group with basal measurements obtained at the recruitment and subsequent measurements performed every 6 months during follow ups. The measurement will involve CASE-cancer, Patient Activation Measure and System Usability Scale. The study will involve 160 survivors (80 survivors of Breast Cancer and 80 survivors of Colorectal Cancer) from four countries, Belgium, Latvia, Slovenia, and Spain. The intervention will be implemented via a digital tool (mHealthApplication), collecting objective biomarkers (vital signs) and subjective biomarkers (PROs) with the support of a (embodied) conversational agent. Additionally, the Clinical Decision Support system (CDSS), including visualization of cohorts and trajectories will enable oncologists to personalize treatment for an efficient care plan and follow-up management. DISCUSSION: We expect that cancer survivors will significantly increase their self-efficacy following the personalized intervention supported by the m-HealthApplication compared to control measurements at recruitment. We expect to observe improvement in healthy habits, disease self-management and self-perceived QoL. Trial registration ISRCTN97617326. https://doi.org/10.1186/ISRCTN97617326 .

Correlation of RECIST, Computed Tomography Morphological Response, and Pathological Regression in Hepatic Metastasis Secondary to Colorectal Cancer: The AVAMET Study.

Background: The prospective phase IV AVAMET study was undertaken to correlate response evaluation criteria in solid tumors (RECIST)-defined response rates with computed tomography-based morphological criteria (CTMC) and pathological response after liver resection of colorectal cancer metastases. Methods: Eligible patients were aged ≥18 years, with Eastern Cooperative Oncology Group (ECOG) performance status 0/1 and histologically-confirmed colon or rectal adenocarcinoma with measurable liver metastases. Preoperative treatment was bevacizumab (7.5 mg on day 1) + XELOX (oxaliplatin 130 mg/m2, capecitabine 1000 mg/m2 bid on days 1-14 q3w). After three cycles, response was evaluated by a multidisciplinary team. Patients who were progression-free and metastasectomy candidates received one cycle of XELOX before undergoing surgery 3-5 weeks later, followed by four cycles of bevacizumab + XELOX. Results: A total of 83 patients entered the study; 68 were eligible for RECIST, 67 for CTMC, and 51 for pathological response evaluation. Of these patients, 49% had a complete or partial RECIST response, 91% had an optimal or incomplete CTMC response, and 81% had a complete or major pathological response. CTMC response predicted 37 of 41 pathological responses versus 23 of 41 responses predicted using RECIST (p = 0.008). Kappa coefficients indicated a lack of correlation between the results of RECIST and morphological responses and between morphological and pathological response rates. Conclusion: CTMC may represent a better marker of pathological response to bevacizumab + XELOX than RECIST in patients with potentially-resectable CRC liver metastases.

Is aflibercept an optimal treatment for wt RAS mCRC patients after progression to first line containing anti-EGFR?

PURPOSE: To determine the efficacy and safety data of aflibercept + FOLFIRI in wt RAS mCRC patients after progression to standard chemotherapy + anti-EGFR treatment. METHODS: Retrospective, observational study in real life conducted in wt RAS mCRC patients treated with FOLFIRI-aflibercept after progression to standard first line chemotherapy + anti-EGFR treatment. RESULTS: A total of 120 patients from 12 Spanish hospitals were enrolled. Median age is 60 years (62.5%/37.5%male/female). Primary tumor site is 24.1%/75.9% right/left-side colon, and 40.8% of patients had a prior resection. All patients had wild-type RAS tumors including 5% of patients with BRAF mutations and received anti-EGFR treatment. At the time aflibercept was initiated, ECOG PS is 0/1 in 96% of patients. Median number of FOLFIRI-aflibercept cycles is 12. Efficacy results: Overall response rate is 33%; progression-free survival (PFS) is 6.9 months (95%CI: 6.1-7.8). Primary tumor resection was the only significant variable related to PFS in the multivariate analysis. Median overall survival (OS) is 14.5 months (95%CI: 9.7-19.3). ECOG and number of metastatic sites were related to OS in multivariate analysis. About 54.1% of patients received a third-line therapy including TAS-102 (23%), regorafenib (18.5%), and capecitabine (9.2%). TOXICITY: Grade 3-4 toxicities were observed in 37.5% of the patients (hematologic 16.6%, hypertension 7.5%, asthenia 5.9%, and perforation 2.5%). Aflibercept dose was reduced in 18.3% of patients. CONCLUSIONS: The results show that patients with wt RAS mCRC who received an anti-EGFR as part of the first-line treatment achieved similar RR, PFS, OS, and toxicities to those reported in VELOUR trial. These results suggest that FOLFIRI-aflibercept after first-line treatment with anti-EGFR is an appropriated option for RAS wt mCRC.

Prognostic factors for survival with nab-paclitaxel plus gemcitabine in metastatic pancreatic cancer in real-life practice: the ANICE-PaC study.

BACKGROUND: Treatment with nab-paclitaxel plus gemcitabine increases survival in patients with metastatic pancreatic cancer. However, the assessment of treatment efficacy and safety in non-selected patients in a real-life setting may provide useful information to support decision-making processes in routine practice. METHODS: Retrospective, multicenter study including patients with metastatic pancreatic cancer, who started first-line treatment with nab-paclitaxel plus gemcitabine between December 2013 and June 2015 according to routine clinical practice. In addition to describing the treatment pattern, overall survival (OS) and progression-free survival (PFS) were assessed for the total sample and the exploratory subgroups based on the treatment and patients' clinical characteristics. RESULTS: All 210 eligible patients had a median age of 65.0 years (range 37-81). Metastatic pancreatic adenocarcinoma was recurrent in 46 (21.9%) patients and de novo in 164 (78.1%); 38 (18%) patients had a biliary stent. At baseline, 33 (18.1%) patients had an ECOG performance status ≥2. Patients received a median of four cycles of treatment (range 1-21), with a median duration of 3.5 months; 137 (65.2%) patients had a dose reduction of nab-paclitaxel and/or gemcitabine during treatment, and 33 (17.2%) discontinued treatment due to toxicity. Relative dose intensity (RDI) for nab-paclitaxel, gemcitabine, and the combined treatment was 66.7%. Median OS was 7.2 months (95% CI 6.0-8.5), and median PFS was 5.0 months (95% CI 4.3-5.9); 50 patients achieved either a partial or complete response (ORR 24.6%). OS was influenced by baseline ECOG PS, NLR and CA 19.9, but not by age ≥ 70 years and/or the presence of hepatobiliary stent or RDI < 85%. All included variables, computed as dichotomous, showed a significant contribution to the Cox regression model to build a nomogram for predicting survival in these patients: baseline ECOG 0-1 vs. 2-3 (p = 0.030), baseline NLR > 3 vs. ≤ 3 (p = 0.043), and baseline CA 19.9 > 37 U/mL vs. ≤37 U/mL (p = 0.004). CONCLUSIONS: Nab-Paclitaxel plus gemcitabine remain effective in a real-life setting, despite the high burden of dose reductions and poorer performance of these patients. A nomogram to predict survival using baseline ECOG performance status, NLR and CA 19.9 is proposed.

Single-Agent Regorafenib in Metastatic Colorectal Cancer Patients with Any RAS or BRAF Mutation Previously Treated with FOLFOXIRI plus Bevacizumab (PREVIUM Trial).

LESSONS LEARNED: RAS- or BRAF-mutated metastatic colorectal cancers (mCRCs) progressing after first-line treatment have a poor prognosis.European and U.S. guidelines include the multikinase inhibitor regorafenib as a standard option for second-line therapy and beyond, based on the results of the randomized phase III CORRECT trial demonstrating improvement in survival.Although stopped prematurely for failing to accrue, the PREVIUM trial, the first prospective interventional study exploring regorafenib as second-line treatment for patients with mCRC bearing RAS or BRAF mutations, failed to demonstrate clinical activity in the population analyzed. BACKGROUND: Patients with RAS- or BRAF-mutated (mut) metastatic colorectal cancer (mCRC) progressing on first-line bevacizumab plus 5-FU/irinotecan/oxaliplatin (FOLFOXIRI) have a poor prognosis. We aimed to assess the efficacy and safety of regorafenib in this population. METHODS: Regorafenib was administered daily for 3 weeks of each 4-week cycle until disease progression or other reason. The primary endpoint was 6-month progression-free survival (PFS). RESULTS: KRAS, NRAS, or BRAF was mutated in mCRC samples in 60%, 20%, and 13% of patients, respectively. Median time from initial diagnosis of metastases to the start of regorafenib and treatment duration was 13.8 months and 7 weeks, respectively. Reasons for discontinuation included disease progression (80%), investigator decision (13%), and adverse events (AEs; 7%). Seven patients (47%) required dose reduction, mostly for asthenia (43%). The most common regorafenib-related grade 3 AEs were asthenia (33%), dysphonia (13%), and hypertension (13%) (Table 1). There were no grade 4 toxicities. No patient was progression-free at 6 months. Median PFS, time to progression (TTP), and overall survival (OS) were 2.2, 2.0, and 3.3 months, respectively. CONCLUSION: Although stopped prematurely for failing to accrue, in the population analyzed, regorafenib failed to demonstrate clinical activity in KRAS- or BRAF-mutated mCRC with progression following first-line with FOLFOXIRI plus bevacizumab, although tolerability was acceptable. Our trial suggests that exploring regorafenib efficacy in an earlier line of therapy should not be undertaken without better population refinement.

From First Line to Sequential Treatment in the Management of Metastatic Pancreatic Cancer.

The current management of patients with metastatic pancreatic ductal adenocarcinoma (mPDAC) is based on systemic chemotherapy. The results of the MPACT and PRODIGE clinical trials have demonstrated that the combination of nab-paclitaxel and gemcitabine (GEM) as well as FOLFIRINOX regimen result in improvement in overall survival when compared to GEM alone. Treatment guidelines now recommend either one of these two regimens as first line treatment for fit patients with mPDAC. Because no head-to-head comparison between the two regimens exists, the selection of one versus the other is based on clinical criteria. The design and eligibility criteria of these two clinical trials are dissimilar, making the results of the MPACT trial more applicable to the general population of patients with mPDAC. In addition, the combination of nab-paclitaxel and GEM is better tolerated and easier to administer in clinical practice than FOLFIRINOX. Furthermore, when the regimens are studied in comparable patient populations the efficacy results are very similar. Nanoliposomal irinotecan plus 5FU has recently demonstrated a significant increase in efficacy rates after a GEM-based treatment. Importantly, treatment of mPDAC should now be considered as a continuum care for patients who are fit, with second and even third line treatments. Different sequential treatment algorithms are proposed based on available data. In retrospective studies, patients who were managed with GEM-based regimens followed by fluoropyrimidine-based regimens appear to have the most favorable outcome.

Multivariable clinical-genetic risk model for predicting venous thromboembolic events in patients with cancer.

BACKGROUND: Venous thromboembolism (VTE) is a leading cause of death among patients with cancer. Outpatients with cancer should be periodically assessed for VTE risk, for which the Khorana score is commonly recommended. However, it has been questioned whether this tool is sufficiently accurate at identifying patients who should receive thromboprophylaxis. The present work proposes a new index, TiC-Onco risk score to be calculated at the time of diagnosis of cancer, that examines patients' clinical and genetic risk factors for thrombosis. METHODS: We included 391 outpatients with a recent diagnosis of cancer and candidates for systemic outpatient chemotherapy. All were treated according to standard guidelines. The study population was monitored for 6 months, and VTEs were recorded. The Khorana and the TiC-Onco scores were calculated for each patient and their VTE predictive accuracy VTEs was compared. RESULTS: We recorded 71 VTEs. The TiC-Onco risk score was significantly better at predicting VTE than the Khorana score (AUC 0.73 vs. 0.58, sensitivity 49 vs. 22%, specificity 81 vs. 82%, PPV 37 vs. 22%, and NPV 88 vs. 82%). CONCLUSIONS: TiC-Onco risk score performed significantly better than Khorana score at identifying cancer patients at high risk of VTE who would benefit from personalised thromboprophylaxis.

Decisiones terapéuticas en el tratamiento del carcinoma hepatocelular y patrones de uso de sorafenib. Resultados del estudio internacional observacional GIDEON en España / Therapeutic decisions in the treatment of hepatocellular carcinoma and patterns of sorafenib use. Results of the international observational GIDEON trial in Spain

INTRODUCCIÓN: GIDEON es un estudio internacional prospectivo, no intervencionista, que evaluó la seguridad de sorafenib en pacientes con carcinoma hepatocelular (CHC) no resecable en la práctica clínica diaria, incluidos pacientes Child-Pugh B. OBJETIVOS: Análisis de datos recogidos en España sobre seguridad y efectividad de sorafenib y los patrones de tratamiento. Métodos Se recogieron los datos demográficos y de la enfermedad, la dosis inicial usada, los acontecimientos adversos emergentes del tratamiento (AA) y las modificaciones de dosis a lo largo del seguimiento. Se valoraron la supervivencia global y el tiempo hasta la progresión de la enfermedad. La eficacia y la seguridad se analizaron en función de la clasificación Child-Pugh y la dosis inicial. RESULTADOS: Se incluyó a 143 pacientes de 19 hospitales españoles. El 24,5% eran pacientes Child-Pugh B. El 90,9% de los pacientes recibió una dosis inicial de 400 mg/12 h. En pacientes Child-Pugh A se modificó más frecuentemente la dosis y la duración del tratamiento fue más larga. La incidencia de AA y de aquellos relacionados con el fármaco fue similar en los pacientes Child-Pugh A y B, aunque los AA graves fueron más frecuentes en los pacientes Child-Pugh B. Los más frecuentes fueron diarrea, fatiga y eritrodisestesia palmo-plantar. La mediana de supervivencia global fue de 384 días, y superior en pacientes Child-Pugh A (593 vs. 211 días en Child-Pugh B); la mediana hasta la progresión de la enfermedad fue de 177 días, similar en ambos subgrupos. CONCLUSIÓN: El perfil de seguridad de sorafenib en pacientes españoles con CHC no resecable es independiente de la función hepática. El estado Child-Pugh no parece influir en el enfoque de dosificación de sorafenib ni en el tiempo hasta la progresión, pero sí parece ser un fuerte predictor de la supervivencia

INTRODUCTION: GIDEON is a non-interventional, prospective, international study that evaluated the safety of sorafenib in patients with unresectable hepatocellular carcinoma (HCC) in daily clinical practice, including Child-Pugh B patients. OBJECTIVES: To analyze data collected in Spain on the safety and efficacy of sorafenib and treatment patterns. Methods Data were collected during follow-up on demographic and disease characteristics, the initial dose used, treatment-emergent adverse events (AEs) and dose modifications. Overall survival was evaluated, as well as time to disease progression. Efficacy and safety were analyzed according to the Child-Pugh classification and the initial dose. RESULTS: We included 143 patients from 19 Spanish hospitals. A total of 24.5% of the patients were Child-Pugh B. An initial dose of 400 mg/12 h was used in 90.9% of patients. In Child-Pugh A patients, dose modifications occurred more frequently and the treatment duration was longer. The incidence of AEs and drug-related AEs were similar in Child-Pugh A and B patients, although serious AEs were more frequent in Child-Pugh B patients. The most common AEs were diarrhea, fatigue and hand-foot skin reactions. The median overall survival was 384 days and was higher in Child-Pugh A patients (593 vs 211 days in Child-Pugh B). The median time to disease progression was 177 days, similar in both subgroups. CONCLUSION: The safety profile of sorafenib in Spanish patients with unresectable HCC is independent of liver function. Child-Pugh status does not seem to influence the approach to sorafenib dosage or time to progression but does seem to be a strong prognostic factor for survival

Biweekly cetuximab in combination with FOLFOX-4 in the first-line treatment of wild-type KRAS metastatic colorectal cancer: final results of a phase II, open-label, clinical trial (OPTIMIX-ACROSS Study).

BACKGROUND: This phase II study aims to evaluate the efficacy and safety of biweekly cetuximab in combination with oxaliplatin, leucovorin, and fluorouracil (FOLFOX-4) as first-line treatment of metastatic wild-type KRAS colorectal cancer. METHODS: Previously untreated patients with wild-type KRAS tumours received biweekly cetuximab (500 mg/m2 on day 1) plus FOLFOX-4 (oxaliplatin 85 mg/m2 on day 1, leucovorin 200 mg/m2 on days 1 and 2, and fluorouracil as a 400 mg/m2 bolus followed by a 22-hour 600 mg/m2 infusion on day 1 and 2). Treatment was continued until disease progression, onset of unacceptable toxicities, metastases surgery, or discontinuation request. The primary endpoint was ORR. RESULTS: The intention-to-treat population included 99 patients with a median age of 64.1 years (range, 34-82). The ORR was 60.6% (95% CI, 50.3% to 70.3%). The median follow-up was 17.8 months; the median OS and PFS were 20.8 and 10.1 months, respectively. Metastases from colorectal cancer were surgically resected in 26 (26.3%) patients, with complete resection achieved in 18 (69.2%) patients. Median PFS and OS in patients undergoing metastatic resection were 12.6 and 29.5 months, respectively. The most common grade 3-4 toxicities were neutropenia (32.3%), acne-like rash (15.2%) and diarrhoea (11.1%). CONCLUSIONS: The efficacy of the biweekly combination of cetuximab with FOLFOX-4 in patients with wild-type KRAS tumours supports the administration of cetuximab in a dosing regimen more convenient for patients and healthcare providers. The activity of the biweekly administration is similar to what has been reported for the weekly regimen. Reported toxicity was also consistent with the known toxicity profile of weekly cetuximab.

A critical review of HER2-positive gastric cancer evaluation and treatment: from trastuzumab, and beyond.

Identification of the importance of human epidermal growth factor receptor-2 (HER2) status, biomarker testing and the development of anti-HER2 treatments have changed the prognosis of breast and gastric cancers. The addition of trastuzumab to chemotherapy has improved outcomes for patients with HER2-positive metastatic adenocarcinoma of the stomach and gastroesophageal junction, but some relevant issues remain to be elucidated or will emerge with new drugs. This article reviews the current state of HER2 in gastric cancer focusing on diagnostic and anti-HER2 targeted treatment issues and the role of trastuzumab in localized disease, and its combination or integration with new therapies.

Gemcitabine and capecitabine as third- or later-line therapy for refractory advanced colorectal cancer: a retrospective study.

AIM: To evaluate gemcitabine plus capecitabine as third-line or later-line therapy in patients with refractory advanced colorectal cancer (CRC) who maintain a good performance status (PS). PATIENTS AND METHODS: We retrospectively evaluated patients who had failed at least two lines of therapy or had contraindication to standard therapy and received gemcitabine (1,000 mg/m(2), d1 biweekly) plus capecitabine (1,700 mg/m(2)/day, d1-7 every two weeks) in a compassionate use program. RESULTS: Thirty-nine patients were enrolled. The majority (85%) had ECOG PS 1. Gemcitabine plus capecitabine was administered as third- and fourth-line in 49% and 23% of patients, respectively; and as fifth-line or later-line in 28%. A clinical benefit of 21% was found. The median progression-free survival and overall survival were 3.0 and 7.3 months, respectively. Toxicity was mild to moderate, with no reported grade 4 toxicities. CONCLUSION: Gemcitabine plus capecitabine was safe and well-tolerated. While the efficacy of this regimen was modest in terms of response, the survival data were acceptable and consistent with previous publications on this setting.
