MODUL cohort 2: an adaptable, randomized, signal-seeking trial of fluoropyrimidine plus bevacizumab with or without atezolizumab maintenance therapy for BRAFwt metastatic colorectal cancer.

BACKGROUND: MODUL is an adaptable, signal-seeking trial designed to test novel agents in predefined patient subgroups in first-line metastatic colorectal cancer (mCRC). PATIENTS AND METHODS: Patients with measurable, unresectable, previously untreated mCRC received induction with ≤8 cycles of FOLFOX + bevacizumab followed by randomization to maintenance treatment comprising control [fluoropyrimidine (FP)/bevacizumab: 5-fluorouracil 1600-2400 mg/m2 46-h intravenous (i.v.) infusion day 1 q2 weeks plus leucovorin 400 mg/m2 2-h infusion i.v. day 1 q2 weeks or capecitabine 1000 mg/m2 b.i.d. orally days 1-14 every 21 days; bevacizumab 5 mg/kg 15-30-min i.v. infusion q2 weeks] or experimental treatment in one of four biomarker-driven cohorts. In patients with BRAF wild-type (BRAFwt) tumors (cohort 2), experimental treatment was FP/bevacizumab + atezolizumab (800 mg 60-min i.v. infusion q2 weeks). Primary efficacy endpoint was progression-free survival (PFS; intent-to-treat population). Enrollment is complete; efficacy and safety findings from cohort 2 are presented. RESULTS: Four hundred and forty-five patients with BRAFwt mCRC were randomized (2 : 1) to maintenance in cohort 2. At a median follow-up of 10.5 months, PFS outcome hypothesis was not met [hazard ratio (HR) 0.92; 95% confidence interval (CI) 0.72-1.17; P = 0.48]; overall survival (OS) was immature. At a median follow-up of 20.3 months (2-year survival follow-up), PFS benefit was also not met (HR 0.95; 95% CI 0.77-1.18; P = 0.666); OS HR with nearly two-thirds of patients with events was 0.83 (95% CI 0.65-1.05; P = 0.117). No new safety signals were identified. The most common grade ≥3 treatment-emergent adverse events (TEAEs) for experimental versus control arms were hypertension (6.1% versus 4.2%), diarrhea (3.1% versus 2.1%), and palmar-plantar erythrodysesthesia syndrome (1.0% versus 2.5%). Four patients experienced TEAEs with fatal outcome, two were study treatment-related: hepatic failure (experimental arm) and large intestine perforation (control arm; bevacizumab-related). CONCLUSIONS: Adding atezolizumab to FP/bevacizumab as first-line maintenance treatment after FOLFOX + bevacizumab induction for BRAFwt mCRC did not improve efficacy outcomes.

How health-related quality of life assessment should be used in advanced colorectal cancer clinical trials.

Traditionally, the efficacy of cancer treatment in patients with advance or metastatic disease in clinical studies has been studied using overall survival and more recently tumor-based end points such as progression-free survival, measurements of response to treatment. However, these seem not to be the relevant clinical end points in current situation if such end points were no validated as surrogate of overall survival to demonstrate the clinical efficacy. Appropriate, meaningful, primary patient-oriented and patient-reported end points that adequately measure the effects of new therapeutic interventions are then crucial for the advancement of clinical research in metastatic colorectal cancer to complement the results of tumor-based end points. Health-related quality of life (HRQoL) is effectively an evaluation of quality of life and its relationship with health over time. HRQoL includes the patient report at least of the way a disease or its treatment affects its physical, emotional and social well-being. Over the past few years, several phase III trials in a variety of solid cancers have assessed the incremental value of HRQoL in addition to the traditional end points of tumor response and survival results. HRQoL could provide not only complementary clinical data to the primary outcomes, but also more precise predictive and prognostic value. This end point is useful for both clinicians and patients in order to achieve the dogma of precision medicine. The present article examines the use of HRQoL in phase III metastatic colorectal cancer clinical trials, outlines the importance of HRQoL assessment methods, analysis, and results presentation. Moreover, it discusses the relevance of including HRQoL as a primary/co-primary end point to support the progression-free survival results and to assess efficacy of treatment in the advanced disease setting.

A need to simplify informed consent documents in cancer clinical trials. A position paper of the ARCAD Group.

Background: In respect of the principle of autonomy and the right of self-determination, obtaining an informed consent of potential participants before their inclusion in a study is a fundamental ethical obligation. The variations in national laws, regulations, and cultures contribute to complex informed consent documents for patients participating in clinical trials. Currently, only few ethics committees seem willing to address the complexity and the length of these documents and to request investigators and sponsors to revise them in a way to make them understandable for potential participants. The purpose of this work is to focus on the written information in the informed consent documentation for drug development clinical trials and suggests (i) to distinguish between necessary and not essential information, (ii) to define the optimal format allowing the best legibility of those documents. Methods: The Aide et Recherche en Cancérologie Digestive (ARCAD) Group, an international scientific committee involving oncologists from all over the world, addressed these issues and developed and uniformly accepted a simplified informed consent documentation for future clinical research. Results: A simplified form of informed consent with the leading part of 1200-1800 words containing all of the key information necessary to meet ethical and regulatory requirements and 'relevant supportive information appendix' of 2000-3000 words is provided. Conclusions: This position paper, on the basis of the ARCAD Group experts discussions, proposes our informed consent model and the rationale for its content.

Interdisciplinary care programme to improve self-management for cancer patients undergoing stem cell transplantation: a prospective non-randomised intervention study.

The purpose of this single-centre prospective non-randomised study was to evaluate the effectiveness of an interdisciplinary care programme to enhance self-management in patients with haematopoietic stem cell transplantation (HSCT). Patients undergoing HSCT, aged >14 years with informed consent were recruited (n = 79). Patients in the intervention group (IG) received standard care plus the SCION-HSCT intervention to counteract three problems after HSCT: muscle weakness, oral mucositis and malnutrition. Control group patients received standard care. Primary endpoint was global health-related quality of life (HRQoL) at discharge (EORTC QLQ C30 v. 3.0). Baseline characteristics were balanced between both groups, except physical performance (ECOG) being significantly lower for patients of the IG. At discharge, no group differences could be seen regarding HRQoL. Non-confirmatory post hoc analyses showed for patients of the IG a shorter duration of hospitalisation (MD -10.90; 95% CI -18.05 to -3.75) and increased activity during hospitalisation (MD 2.44; 95% CI 1.27-3.61). In conclusion, clinical effectiveness of the intervention could not be proven with respect to the aspired improvement of HRQoL. However, the nurse-led interdisciplinary caring programme could be carried out in every day ward routine. Further research should focus on working mechanisms of complex interventions aiming to improve HRQoL of patients undergoing HSCT.

Quality of life assessment in patients with metastatic colorectal cancer receiving maintenance therapy after first-line induction treatment: a preplanned analysis of the phase III AIO KRK 0207 trial.

BACKGROUND: First-line maintenance strategies are a current matter of debate in the management of mCRC. Their impact on patient's health-related quality of life (HRQOL) has not yet been evaluated. The objective of this study was to assess whether differences in HRQOL during any active maintenance treatment compared with no maintenance treatment exist. PATIENT AND METHODS: Eight hundred and thirty-seven patients were enrolled in the AIO KRK 0207 trial. Four hundred and seventy-two underwent randomization (after 24 weeks of induction treatment) into one of the maintenance arms: FP plus Bev (arm A), Bev alone (arm B), or no active treatment (arm C). HRQOL were assessed every 6 weeks during induction and maintenance treatment independent from treatment stop, delay, or modification, and also continued after progression, using the EORTC QLQ-C30, QLQ-CR29. The mean value of the global quality of life dimension (GHS/QoL) of the EORTC QLQ-C30, calculated as the average of all available time points after randomization was considered as pre-specified main endpoint. Additionally, EORTC QLQ-C30 response scores were analyzed. RESULTS: For HRQOL analysis, 413 patients were eligible (arm A: 136; arm B: 142, arm C: 135). Compliance rate with the HRQOL questionnaires was 95% at time of randomization and remained high during maintenance (98%, 99%, 97% and 97% at week 6, 12, 18 and 24). No significant differences between treatment arms in the mean GHS/QoL scores were observed at any time point. Also, rates of GHS/QoL score deterioration were similar (20.5%; 17.2% and 20.7% of patients), whereas a score improvement occurred in 36.1%; 43.8% and 42.1% (arms A, B and C). CONCLUSION: Continuation of an active maintenance treatment with FP/Bev after induction treatment was neither associated with a detrimental effect on GHS/QoL scores when compared with both, less active treatment with Bev alone or no active treatment.

Outcome according to KRAS-, NRAS- and BRAF-mutation as well as KRAS mutation variants: pooled analysis of five randomized trials in metastatic colorectal cancer by the AIO colorectal cancer study group.

BACKGROUND: To explore the impact of KRAS, NRAS and BRAF mutations as well as KRAS mutation variants in patients with metastatic colorectal cancer (mCRC) receiving first-line therapy. PATIENTS AND METHODS: A total of 1239 patients from five randomized trials (FIRE-1, FIRE-3, AIOKRK0207, AIOKRK0604, RO91) were included into the analysis. Outcome was evaluated by the Kaplan-Meier method, log-rank tests and Cox models. RESULTS: In 664 tumors, no mutation was detected, 462 tumors were diagnosed with KRAS-, 39 patients with NRAS- and 74 patients with BRAF-mutation. Mutations in KRAS were associated with inferior progression-free survival (PFS) and overall survival (OS) [multivariate hazard ratio (HR) for PFS: 1.20 (1.02-1.42), P = 0.03; multivariate HR for OS: 1.41 (1.17-1.70), P < 0.001]. BRAF mutation was also associated with inferior PFS [multivariate HR: 2.19 (1.59-3.02), P < 0.001] and OS [multivariate HR: 2.99 (2.10-4.25), P < 0.001]. Among specific KRAS mutation variants, the KRAS G12C-variant (n = 28) correlated with inferior OS compared with unmutated tumors [multivariate HR 2.26 (1.25-4.1), P = 0.001]. A similar trend for OS was seen in the KRAS G13D-variant [n = 71, multivariate HR 1.46 (0.96-2.22), P = 0.10]. More frequent KRAS exon 2 variants like G12D [n = 152, multivariate HR 1.17 (0.86-1.6), P = 0.81] and G12V [n = 92, multivariate HR 1.27 (0.87-1.86), P = 0.57] did not have significant impact on OS. CONCLUSION: Mutations in KRAS and BRAF were associated with inferior PFS and OS of mCRC patients compared with patients with non-mutated tumors. KRAS exon 2 mutation variants were associated with heterogeneous outcome compared with unmutated tumors with KRAS G12C and G13D (trend) being associated with rather poor survival.

ESMO consensus guidelines for the management of patients with metastatic colorectal cancer.

Colorectal cancer (CRC) is one of the most common malignancies in Western countries. Over the last 20 years, and the last decade in particular, the clinical outcome for patients with metastatic CRC (mCRC) has improved greatly due not only to an increase in the number of patients being referred for and undergoing surgical resection of their localised metastatic disease but also to a more strategic approach to the delivery of systemic therapy and an expansion in the use of ablative techniques. This reflects the increase in the number of patients that are being managed within a multidisciplinary team environment and specialist cancer centres, and the emergence over the same time period not only of improved imaging techniques but also prognostic and predictive molecular markers. Treatment decisions for patients with mCRC must be evidence-based. Thus, these ESMO consensus guidelines have been developed based on the current available evidence to provide a series of evidence-based recommendations to assist in the treatment and management of patients with mCRC in this rapidly evolving treatment setting.

Impact of age and medical comorbidity on adjuvant treatment outcomes for stage III colon cancer: a pooled analysis of individual patient data from four randomized, controlled trials.

BACKGROUND: Adjuvant oxaliplatin plus capecitabine or leucovorin/5-fluorouracil (LV/5-FU) (XELOX/FOLFOX) is the standard of care for stage III colon cancer (CC); however, there is disagreement regarding oxaliplatin benefit in patients aged >70. In most analyses, the impact of medical comorbidity (MC) has not been assessed. Efficacy and safety of adjuvant XELOX/FOLFOX versus LV/5-FU were compared with respect to age and MC using pooled data from four randomized, controlled trials, selected for access to patient-level MC data and including commonly endorsed and utilized regimens. PATIENTS AND METHODS: Individual data from patients with stage III CC in NSABP C-08, XELOXA, X-ACT, and AVANT were pooled, excluding bevacizumab-treated patients. Patients were grouped by treatment, MC (low versus high), or age (<70 versus ≥70), and compared for disease-free survival (DFS), overall survival (OS), and adverse events (AEs). Multivariable Cox proportional hazards regression controlled for gender, T stage, and N stage. RESULTS: DFS benefits were shown for XELOX/FOLFOX versus LV/5-FU regardless of age or MC, although benefits were modestly attenuated for patients aged ≥70. Hazard ratios were 0.68 (P < 0.0001) and 0.77 (P < 0.014) for <70 and ≥70 age groups; 0.69 (P < 0.0001) and 0.59 (P < 0.0001) for Charlson Comorbidity Index ≤1 and >1 groups; and 0.70 (P < 0.0001) and 0.58 (P < 0.0001) for National Cancer Institute Combined Index ≤1 and >1 groups. OS was also significantly improved in all groups. Grade 3/4 serious AE rates were comparable across cohorts and MC scores and higher in patients aged ≥70. Oxaliplatin-relevant grade 3/4 AEs, including neuropathy, were comparable across ages and MC scores. CONCLUSIONS: Results further support consideration of XELOX or FOLFOX as standard treatment options for the adjuvant management of stage III CC in all age groups and in patients with comorbidities, consistent with those who were eligible for these clinical trials.

TEMHEAD: a single-arm multicentre phase II study of temsirolimus in platin- and cetuximab refractory recurrent and/or metastatic squamous cell carcinoma of the head and neck (SCCHN) of the German SCCHN Group (AIO).

BACKGROUND: Squamous cell carcinoma of the head and neck (SCCHN) is a common disease, which has a poor prognosis after failure of therapy. Activation of the PI3K-AKT-mTOR axis is commonly detected in recurrent or metastatic SCCHN, and provided the rationale for the clinical phase II trial in pretreated SCCHN. PATIENTS AND METHODS: The primary end point was the progression-free survival rate (PFR) at 12 weeks. Forty eligible patients have been recruited after failure of platinum chemotherapy and cetuximab. A preplanned futility analysis was successfully passed after ≥1 success was detected in 20 patients. Secondary objectives consisted of progression-free survival (PFS), disease control rate (DCR), overall survival (OS), safety and tolerability, and predictive biomarkers for KRAS, BRAF, PIK3CA mutations, and HPV status. Archived tumor tissue was analyzed for DNA sequence. RESULTS: A total of 40 patients were eligible. The PFR at 12 weeks was 40% (95% CI 25.0-54.6). The median PFS and OS were 56 days (95% CI 36-113 days) and 152 days (76-256 days), respectively. In 33 assessable patients, disease stabilization occurred in 57.6%, with tumor shrinkage in 13 patients (39.4%). Overall, the treatment was well tolerated. Fatigue (47.5%), anemia (25.0%), nausea (20.0%), and pneumonia (20.0%) were the most common adverse events. Neither PIK3CA mutations, nor HPV status were predictive for success with temsirolimus treatment. No mutations were found for KRAS or BRAF. CONCLUSION: Tumor shrinkage and efficacy parameter indicate that inhibition of the PI3K-AKT-mTOR axis was a putative novel treatment paradigm for SCCHN. We could not identify parameters predictive for treatment success of temsirolimus, which underscores the need for refinement of the molecular analysis in future studies. CLINICAL TRIALS NUMBER: NCT01172769.

Quality assurance in the treatment of colorectal cancer: the EURECCA initiative.

Colorectal cancer is one of the most common cancers in Europe. Over the past few decades, important advances have been made in screening, staging and treatment of colorectal cancer. However, considerable variation between and within European countries remains, which implies that further improvements are possible. The most important remaining question now is: when are we, health care professionals, delivering the best available care to patients with colon or rectal cancer? Currently, quality assurance is a major issue in colorectal cancer care and quality assurance awareness is developing in almost all disciplines involved in the treatment of colorectal cancer patients. Quality assurance has shown to be effective in clinical trials. For example, standardisation and quality control were introduced in the Dutch TME trial and led to marked improvements of local control and survival in rectal cancer patients. Besides, audit structures can also be very effective in monitoring cancer management and national audits showed to further improve outcome in colorectal cancer patients. To reduce the differences between European countries, an international, multidisciplinary, outcome-based quality improvement programme, European Registration of Cancer Care (EURECCA), has been initiated. In the near future, the EURECCA dataset will perform research on subgroups as elderly patients or patients with comorbidities, which are often excluded from trials. For optimal colorectal cancer care, quality assurance in guideline formation and in multidisciplinary team management is also of great importance. The aim of this review was to create greater awareness and to give an overview of quality assurance in the management of colorectal cancer.

Epidemiology and natural history of central venous access device use and infusion pump function in the NO16966 trial.

BACKGROUND: Central venous access devices in fluoropyrimidine therapy are associated with complications; however, reliable data are lacking regarding their natural history, associated complications and infusion pump performance in patients with metastatic colorectal cancer. METHODS: We assessed device placement, use during treatment, associated clinical outcomes and infusion pump performance in the NO16966 trial. RESULTS: Device replacement was more common with FOLFOX-4 (5-fluorouracil (5-FU)+oxaliplatin) than XELOX (capecitabine+oxaliplatin) (14.1% vs 5.1%). Baseline device-associated events and post-baseline removal-/placement-related events occurred more frequently with FOLFOX-4 than XELOX (11.5% vs 2.4% and 8.5% vs 2.1%). Pump malfunctions, primarily infusion accelerations in 16% of patients, occurred within 1.6-4.3% of cycles. Fluoropyrimidine-associated grade 3/4 toxicity was increased in FOLFOX-4-treated patients experiencing a malfunction compared with those who did not (97 out of 155 vs 452 out of 825 patients), predominantly with increased grade 3/4 neutropenia (53.5% vs 39.8%). Febrile neutropenia rates were comparable between patient cohorts±malfunction. Efficacy outcomes were similar in patient cohorts±malfunction. CONCLUSIONS: Central venous access device removal or replacement was common and more frequent in patients receiving FOLFOX-4. Pump malfunctions were also common and were associated with increased rates of grade 3/4 haematological adverse events. Oral fluoropyrimidine-based regimens may be preferable to infusional 5-FU based on these findings.

Effort myocardial ischemia during chemotherapy with 5-fluorouracil: an underestimated risk.

BACKGROUND: Effort-induced myocardial ischemia (EMI) has been seldom described. Aims of our study were (A) to evaluate the prevalence of EMI during long-lasting 5-FU infusion; (B) to identify possible risk factors of EMI during 5-FU infusion. PATIENTS AND METHODS: For the purpose (A), we prospectively evaluated a group of patients undergoing in-hospital continuous infusion (c.i.) of 5-FU. Patients with rest ischemia were excluded. Among 358 consecutive patients, 21 (5.9%) had rest ischemia; 109 could not perform a stress test. The remaining 228 patients underwent a treadmill stress test (TST) after >46 h of 5-FU infusion. For the purpose (B), we compared the characteristics of patients with EMI (including 3 previously described in a 2001 paper) with those without EMI. RESULTS: Among 228 patients, 16 (6.9%) had EMI. These 16 had a second TST after stopping 5-FU: in 14, it was negative, 2 patients with coronary artery disease had milder ischemia. The whole group of 231 (including 3 described in a previous paper) patients undergoing TST included 148 males and 83 females, with mean age of 57.5. Cardiovascular risk factors were present in 178 of them. Eight patients had ischemic heart disease. Among 19 patients with EMI, 7 had angina, 12 silent ischemia. ST segment at ECG was elevated in 10 patients, depressed in 9. Comparing the group with toxicity and the one without, the only significant difference was the complaint of atypical symptoms at rest before the TST. No difference was observed as regards: chemotherapy schedule (chronic c.i. in 49, 5 days in 178, FOLFOX type in 12), coronary risk factors or heart disease. CONCLUSIONS: EMI is as frequent as rest ischemia during 5-FU infusion. Patients undergoing 5-FU continuous infusions should be adviced to avoid unusual efforts, to refer any cardiac symptom, and should be investigated for EMI.

Treatment of adolescents and young adults (AYA) with cancer in a multidisciplinary setting: on the way to a highly specialized AYA unit.

Further survival improvements of adolescents and young adults (AYA) with cancer are clearly affected by biological characteristics of the malignancies and age-specific needs. Multidisciplinary teams drawing expertice from both pediatric and adult cancer teams as well as clinical trials are required to meet the age specific needs of AYA patients with cancer. In 2011, the first AYA unit was established at the University Hospital Halle (Saale), where patients with newly-diagnosed cancer aged 15-25 are treated interdisciplinary by pediatric and adult oncologists. The enrollment into pediatric or adult clinical trials is controlled by age 18. Over the last 2 years, 19 AYA with cancer have been treated at the unit; and, in turn patients and their relatives reflected a high satisfaction with the offered novel health care approach. In the scope of the future Comprehensive Cancer Center at the University Hospital Halle (Saale), a complete ward is planned for all admitted AYA up to 25 years with cancer. The patients will be treated by a tumor-specialized multidisciplinary team of adult or pediatric oncologists and oncological surgeons. Therefore, we intend to establish a special teaching curriculum for physicians, nurses and psychosocial health care staff. Rather than age, cancer biology of a malignancy, surveillance data of late side effects as well as the age-specific needs of AYA patients will be crucial for best treatment options.

Capecitabine/irinotecan or capecitabine/oxaliplatin in combination with bevacizumab is effective and safe as first-line therapy for metastatic colorectal cancer: a randomized phase II study of the AIO colorectal study group.

BACKGROUND: This randomized phase II trial investigated the efficacy and safety of capecitabine/oxaliplatin (CapOx) plus bevacizumab and dose-modified capecitabine/irinotecan (mCapIri) plus bevacizumab as first-line therapy in patients with metastatic colorectal cancer (mCRC). PATIENTS AND METHODS: Patients received bevacizumab 7.5 mg/kg with oxaliplatin 130 mg/m(2)/day 1 plus capecitabine 1000 mg/m(2) bid/days 1-14 or with irinotecan 200 mg/m(2)/day 1 plus capecitabine 800 mg/m(2) bid/days 1-14 both every 21 days. The primary end point was 6 months progression-free survival (PFS). RESULTS: A total of 255 patients were enrolled. The intent-to-treat population comprised 247 patients (CapOx-bevacizumab: n = 127; mCapIri-bevacizumab: n = 120). The six-month PFS rates were 76% (95% CI, 69%-84%) and 84% (95% CI, 77%-90%). Median PFS and OS were 10.4 months (95% CI, 9.0-12.0) and 24.4 months (95% CI, 19.3-30.7) with CapOx-bevacizumab, and 12.1 months (95% CI, 10.8-13.2) and 25.5 months (95% CI, 21.0-31.0) with mCapIri-bevacizumab. Grade 3/4 diarrhea as predominant toxic effect occurred in 22% of patients with CapOx-bevacizumab and in 16% with mCapIri-bevacizumab. CONCLUSIONS: Both, CapOx-bevacizumab and mCapIri-bevacizumab, show promising activity and an excellent toxic effect profile. Efficacy is in the range of other bevacizumab-containing combination regimen although lower doses of irinotecan and capecitabine were selected for mCapIri.

Prognostic and predictive value of VEGF, sVEGFR-2 and CEA in mCRC studies comparing cediranib, bevacizumab and chemotherapy.

BACKGROUND: The prognostic/predictive value of potential vascular endothelial growth factor (VEGF) signalling biomarkers was evaluated retrospectively using samples from two randomized Phase III studies (HORIZON II and III) investigating cediranib in metastatic colorectal cancer (mCRC). METHODS: Baseline levels of VEGF, soluble VEGF receptor-2 (sVEGFR-2) and carcinoembryonic antigen (CEA) were measured in plasma/serum samples collected from patients participating in HORIZON II (n=860; FOLFOX/XELOX plus cediranib 20 mg (n=502) or placebo (n=358)) and HORIZON III (n=1422; mFOLFOX6 plus cediranib 20 mg (n=709) or bevacizumab (n=713)). Median biomarker baseline levels determined cutoff values for the patient subgroups. RESULTS: Baseline data were available for 88-97% of patients/study (>2000 patients). In both the studies, high baseline VEGF and CEA were associated with worse outcomes for progression-free survival (PFS) and overall survival (OS) independent of treatment (HORIZON II OS: VEGF, hazard ratio (HR)=1.35 (95% confidence interval (CI): 1.12-1.63); CEA, HR=1.63 (1.36-1.96); HORIZON III OS: VEGF, HR=1.32 (1.12-1.54); CEA, HR=1.50 (1.29-1.76)). sVEGFR-2 was not prognostic for PFS/OS. Baseline VEGF and CEA were not predictive for PFS/OS outcome to cediranib treatment; low sVEGFR-2 was associated with a trend towards improved cediranib effect in HORIZON II. CONCLUSION: Baseline VEGF and CEA levels were treatment-independent prognostic biomarkers for PFS and OS in both the studies.

ESMO Consensus Guidelines for management of patients with colon and rectal cancer. a personalized approach to clinical decision making.

Colorectal cancer (CRC) is the most common tumour type in both sexes combined in Western countries. Although screening programmes including the implementation of faecal occult blood test and colonoscopy might be able to reduce mortality by removing precursor lesions and by making diagnosis at an earlier stage, the burden of disease and mortality is still high. Improvement of diagnostic and treatment options increased staging accuracy, functional outcome for early stages as well as survival. Although high quality surgery is still the mainstay of curative treatment, the management of CRC must be a multi-modal approach performed by an experienced multi-disciplinary expert team. Optimal choice of the individual treatment modality according to disease localization and extent, tumour biology and patient factors is able to maintain quality of life, enables long-term survival and even cure in selected patients by a combination of chemotherapy and surgery. Treatment decisions must be based on the available evidence, which has been the basis for this consensus conference-based guideline delivering a clear proposal for diagnostic and treatment measures in each stage of rectal and colon cancer and the individual clinical situations. This ESMO guideline is recommended to be used as the basis for treatment and management decisions.

[Unexplained fever and B-symptoms in a young male Black African]. / Unklares Fieber und B-Symptome bei einem jungen Schwarzafrikaner.

An immunocompetent Nigerian developed a fulminant hemophagocytic lymphohistiocytosis due to Epstein-Barr virus reactivation. The patient initially presented with fever, hepatosplenomegaly and pancytopenia. The clinical status of our patient deteriorated quickly despite treatment with corticoids. Escalation of immunosuppressive treatment was not possible. He died of lung, liver and circulatory failure in our intensive care unit.Hemophagocytic lymphohistiocytosis is a rare disease characterized by inflammation due to prolonged and excessive activation of antigen-presenting cells. High plasma ferritin levels and phagocytosis of hematopoetic cells in bone marrow, spleen and liver lead to the diagnosis. Hemophagocytic lymphohistiocytosis should therefore be included in the differential diagnosis in patients with persistent fever, hepatosplenomegaly and cytopenia.

Role of the multidisciplinary team in breast cancer management: results from a large international survey involving 39 countries.

BACKGROUND: The optimal management of patients with breast cancer (BC) requires the expertise of specialists from different disciplines. This has led to the evolution of multidisciplinary teams (MDTs), allowing all key professionals to jointly discuss individual patients and to contribute independently to clinical decisions. Data regarding BC MDTs in different regions and countries are scarce. METHODS: The investigators of a large global phase III adjuvant BC trial being conducted by the Breast International Group were invited to respond to a questionnaire about the extent, structure, and function of BC MDTs. RESULTS: One hundred and fifty-two responses from 39 countries were received, and remarkable differences were noted in different geographic regions. Sixty-five percent of the respondents from eastern Europe, 63% from western Europe, 35% from Asia, and 25% from South America declared that MDT was a mandatory part of BC care in their country. Ninety percent of the respondents from Europe stated their MDTs met weekly, compared with only half of the respondents from Asia. CONCLUSION: This survey is perhaps the first large-scale effort to collect information regarding BC MDTs from different parts of the world and provides objective information of frequency, composition, function, and working mechanism of BC MDTs.
