Skin toxicity and quality of life in patients with metastatic colorectal cancer during first-line panitumumab plus FOLFIRI treatment in a single-arm phase II study

Background: Integument-related toxicities are common during epidermal growth factor receptor (EGFR)-targeted therapy. Panitumumab is a fully human monoclonal antibody targeting the EGFR that significantly improves progression-free survival when added to chemotherapy in patients with metastatic colorectal cancer who have wild-type (WT) KRAS tumours. Primary efficacy and tolerability results from a phase II single-arm study of first-line panitumumab plus FOLFIRI in patients with metastatic colorectal cancer have been reported. Here we report additional descriptive tolerability and quality of life data from this trial. Methods: Integument-related toxicities and quality of life were analysed; toxicities were graded using modified National Cancer Institute Common Toxicity Criteria. Kaplan-Meier estimates of time to and duration of first integument-related toxicity were prepared. Quality of life was measured using EuroQoL EQ-5D and EORTC QLQ-C30. Best overall response was analysed by skin toxicity grade and baseline quality of life. Change in quality of life was analysed by skin toxicity severity. Results: 154 patients were enrolled (WT KRAS n = 86; mutant KRAS n = 59); most (98%) experienced integument-related toxicities (most commonly rash [42%], dry skin [40%] and acne [36%]). Median time to first integument-related toxicity was 8 days; median duration was 334 days. Overall, proportionally more patients with grade 2+ skin toxicity responded (56%) compared with those with grade 0/1 (29%). Mean overall EQ-5D health state index scores (0.81 vs. 0.78), health rating scores (72.5 vs. 71.0) and QLQ-C30 global health status scores (65.8 vs. 66.7) were comparable at baseline vs. safety follow-up (8 weeks after completion), respectively and appeared unaffected by skin toxicity severity. Conclusions: First-line panitumumab plus FOLFIRI has acceptable tolerability and appears to have little impact on quality of life, despite the high incidence of integument-related toxicity

Inhibition of the vascular epidermal growth factor (VEGF) by the VEGF antibody bevacizimab has been reported recently. A total of 403 patients were randomized to receive the IFL regimen plus placebo and 412 IFL plus bevacizumab (12). The response rate (35 % vs. 45%, p=0.003), time to progression (6.2 vs. 10.4 months, p<0.0001) and overall survival (15.6 vs. 20.3 months, p=0.0003) were all in favor of the combination treatment. This is the first study to demonstrate VEGF inhibition as a successful target

EORTC Cancer in the Elderly Task Force guidelines for the use of colony-stimulating factors in elderly patients with cancer

Increasing age is not, in itself, a contraindication to cancer chemotherapy. Myelosuppression, however, a common adverse consequence of the administration of many standard-dose chemotherapy regimens to both young and elderly patients with cancer, increases with age. The risk of development of febrile neutropenia may contribute to a reluctance to administer chemotherapy in the elderly patient population. We conducted a detailed literature search (1992-2002) to derive evidence-based conclusions on the value of prophylactic colony-stimulating factor (CSF) administration in elderly patients receiving chemotherapy. Sufficient evidence allows us to affirm that prophylactic granulocyte colony-stimulating factor (G-CSF) reduces the incidence of chemotherapy-induced neutropenia, febrile neutropenia and infections in elderly patients receiving myelotoxic chemotherapy for non-Hodgkin's lymphoma (NHL), small-cell lung cancer (SCLC) or urothelial tumours. Lack of available trial data does not allow similar conclusions to be drawn for other cancers studied, but it is likely that similar benefits would accrue from the use of prophylactic G-CSF. There is insufficient evidence to extend this recommendation to include the use of granulocyte-macrophage colony-stimulating factor (GM-CSF). There are insufficient data available to allow the evaluation of the impact of prophylactic CSF on the incidence of toxic deaths in elderly patients with cancer and this is a crucial question for geriatric oncology practice. There is no evidence in elderly patients that the delivery of standard-dose chemotherapy on schedule improves efficacy measures. The data show that febrile neutropenic events are more likely to occur during the first and second cycles of chemotherapy, thus prophylactic measures should be considered early in the course of treatment. Furthermore, since systematic dose reduction can impact on outcome, primary prophylactic use of G-CSF for all elderly patients receiving curative myelotoxic chemotherapy (cyclophosphamide, doxorubicin, vincristine and prednisolone (CHOP) or CHOP-like) is indicated and we suggest a risk-adapted strategy with primary prophylactic G-CSF administration in high-risk patients. Dose intensification, through dose interval reduction, facilitated by prophylactic G-CSF, improved survival in elderly patients with some specific diseases. There is a need for further well-designed studies to identify the elderly patients who will benefit most from prophylactic G-CSF. To achieve this, we strongly urge the design of and participation in further trials. © 2003 Elsevier Ltd. All rights reserved.SCOPUS: ar.jinfo:eu-repo/semantics/publishe

First-line panitumumab plus irinotecan/5-fluorouracil/leucovorin treatment in patients with metastatic colorectal cancer

Purpose Panitumumab monotherapy is approved for KRAS wild-type (WT) metastatic colorectal cancer (mCRC) progressing after standard chemotherapy. This study evaluated first-line panitumumab plus FOLFIRI in patients with mCRC. Methods In this phase II, single-arm study, panitumumab (6 mg/kg) and FOLFIRI [irinotecan (180 mg/m(2)) and leucovorin (400 mg/m(2)) followed by a 5-fluorouracil 400 mg/m(2) bolus and a 2,400-3,000 mg/m(2) continuous infusion] were administered every 14 days until progression. Data were analysed descriptively overall and by tumour KRAS status. Results KRAS data were available for 145/154 (94%) patients: 59% KRAS WT and 41% mutant (MT); mean follow-up was 39.5 versus 35.8 weeks, respectively. Objective responses occurred in 49% of patients: 56% versus 38% in the KRAS WT versus MT groups [(18% difference (95% CI 1-35%); odds ratio 2.1 (95% CI 1.0-4.4)]; median duration of response was 13.0 versus 7.4 months. More patients in the WT group underwent R0 resection (8% vs. 5%); median progression-free survival also favoured this group (8.9 vs. 7.2 months). The most common adverse events (any grade) were integument toxicities (98%), diarrhoea (79%) and stomatitis/oral mucositis (51%). Conclusions As expected, consistently favourable efficacy was observed in patients with KRAS WT versus MT tumours receiving first-line panitumumab plus FOLFIRI treatment

Shanghai international consensus on diagnosis and comprehensive treatment of colorectal liver metastases (version 2019)

The liver is the most common anatomical site for hematogenous metastases from colorectal cancer. Therefore effective treatment of liver metastases is one of the most challenging elements in the management of colorectal cancer. However, there is rare available clinical consensus or guideline only focusing on colorectal liver metastases. After six rounds of discussion by 195 clinical experts of the Shanghai International Consensus Expert Group on Colorectal Liver Metastases (SINCE) from 29 countries or regions, the Shanghai Consensus has been finally completed, based on current research and expert experience. The consensus emphasized the principle of multidisciplinary team, provided detailed diagnosis approaches, and guided precise local and systemic treatments. This Shanghai Consensus might be of great significance to standardized diagnosis and treatment of colorectal liver metastases all over the world.status: publishe

Imatinib dose reduction in major molecular response of chronic myeloid leukemia: results from the German Chronic Myeloid Leukemia-Study IV

Standard first-line therapy of chronic myeloid leukemia is treatment with imatinib. In the randomized German Chronic Myeloid Leukemia-Study IV, more potent BCR-ABL inhibition with 800 mg ('high-dose') imatinib accelerated achievement of a deep molecular remission. However, whether and when a de-escalation of the dose intensity under high-dose imatinib can be safely performed without increasing the risk of losing deep molecular response is unknown. To gain insights into this clinically relevant question, we analyzed the outcome of imatinib dose reductions from 800 mg to 400 mg daily in the Chronic Myeloid Leukemia-Study IV. Of the 422 patients that were randomized to the 800 mg arm, 68 reduced imatinib to 400 mg after they had achieved at least a stable major molecular response. Of these 68 patients, 61 (90%) maintained major molecular remission on imatinib at 400 mg. Five of the seven patients who lost major molecular remission on the imatinib standard dose regained major molecular remission while still on 400 mg imatinib. Only two of 68 patients had to switch to more potent kinase inhibition to regain major molecular remission. Importantly, the lengths of the intervals between imatinib high-dose treatment before and after achieving major molecular remission were associated with the probabilities of maintaining major molecular remission with the standard dose of imatinib. Taken together, the data support the view that a deep molecular remission achieved with high-dose imatinib can be safely maintained with standard dose in most patients

ESMO / ASCO Recommendations for a Global Curriculum in Medical Oncology Edition 2016

The European Society for Medical Oncology (ESMO) and the American Society of Clinical Oncology (ASCO) are publishing a new edition of the ESMO/ ASCO Global Curriculum (GC) thanks to contribution of 64 ESMOappointed and 32 ASCO-appointed authors. First published in 2004 and updated in 2010, the GC edition 2016 answers to the need for updated recommendations for the training of physicians in medical oncology by defining the standard to be fulfilled to qualify as medical oncologists. At times of internationalisation of healthcare and increased mobility of patients and physicians, the GC aims to provide state-of-the-art cancer care to all patients wherever they live. Recent progress in the field of cancer research has indeed resulted in diagnostic and therapeutic innovations such as targeted therapies as a standard therapeutic approach or personalised cancer medicine specialised training for medical oncology trainees. Thus, several new chapters on technical contents such as molecular pathology, translational research or molecular imaging and on conceptual attitudes towards human principles like genetic counselling or survivorship have been integrated in the GC. The GC edition 2016 consists of 12 sections with 17 subsections, 44 chapters and 35 subchapters, respectively. Besides renewal in its contents, the GC underwent a principal formal change taking into consideration modern didactic principles. It is presented in a template-based format that subcategorises the detailed outcome requirements into learning objectives, awareness, knowledge and skills. Consecutive steps will be those of harmonising and implementing teaching and assessment strategies
