Abstract Background Currently available predictive models for chemotherapy-related toxicity are not sufficiently discriminative in older patients with cancer and do not consider moderate toxicities. ...The purpose of this study was to identify factors associated with moderate and severe chemotherapy toxicities in older patients with cancer. Materials and methods Patients aged 70+ recruited in the prospective ELCAPA cohort were analyzed. A total of 837 patients with data on toxicities had received chemotherapy without other systemic treatment and were included between 2015 and 2022. To adjust for any imbalances in the distribution of covariates between patients receiving single-agent chemotherapy vs combination chemotherapy, we applied overlap weighting (a propensity-score-based technique). We used multinomial logistic regression. Results Median (interquartile range) age was 81 (77-84). Forty-one percent experienced moderate toxicity, and 33% experienced severe toxicity. Hematologic toxicities accounted for 53% of severe toxicities and 66% of moderate toxicities. Age <80 years, cancer type, metastatic status, Eastern Cooperative Oncology Group performance status (ECOG-PS) >1, no cognitive impairment were associated with combination chemotherapy decision. In a univariate analysis with overlap weighting, no factors were associated with moderate toxicity. Hemoglobin < 10 g/dL and a CIRS-G score >12 were associated with severe toxicity. In a multivariate analysis, only hemoglobin < 10 g/dL was independently associated with severe toxicity, adjusted OR 2.96 (95% CI, 1.20-7.29). Conclusion By addressing indication bias for combination chemotherapy decision, only anemia and not cancer type, combination chemotherapy was predicting for severe chemotherapy-related toxicity in older patients with cancer. We did not find any predictors of moderate chemotherapy-related toxicity.
Cancer management is changing rapidly. Changes in practices are not all transferable to the elderly population, which is heterogeneous. The description of the intrinsic toxicity of anti-cancer ...treatments is insufficient in the elderly. Recent studies dedicated to the elderly incorporate composite evaluation criteria combining efficacy and toxicity with a broad definition including, among other things, loss of functional autonomy. These new data acquired, as well as new organisations integrating the new profession of advanced practice nurse in oncogeriatrics will enable us to better respond to the challenge of caring for elderly patients in the future.
Two patients underwent percutaneous image-guided electrochemotherapy on blastic spine metastases involving posterior walls of the lumbar vertebral bodies with epidural extension. These treatments ...were performed safely under cone beam computed tomography. Local tumor control was obtained on the subsequent follow-up as well as pain relief and disability improvement. Electrochemotherapy might be considered for patients with thus far no other alternative in order to obtain tumor control and improvement in patients’ quality of life.
Since the advent of the HER2 biomarker allowing access to treatment with trastuzumab, we observe an explosion in research for biomarkers, in which the economic pressure linked to the costs of ...developing new products must not be overlooked, in order to better select the molecules to be developed and the patients who can benefit from them. Personalized medicine takes a little more space each year in the overall care of our patients and the search for specific indicators, has become unavoidable. Rapid identification of oncogenic changes, their therapeutic targeting and the anticipation of resistance or toxicity mechanisms is a challenge. From blood markers, proteins to tumor genomic profiling and new markers in medical imaging, clinicians, researchers, and patients all are looking for the Holy Grail. This article synthetizes oncology resident's reflexions during the ESMO congress which took place in Copenhagen from 7 to 11 October 2016. The aim was to select the most relevant or promising results for future clinical practice.
