Effectiveness of a phone-based nurse monitoring assessment and intervention for chemotherapy-related toxicity: A randomized multicenter trial

PurposeAnticancer treatment-related toxicities can impact morbidity and mortality, hamper the administration of treatment, worsen the quality of life and increase the burden on the healthcare system. Therefore, their prompt identification is crucial. NICSO (Italian Network for Supportive Care in Cancer) conducted a nationwide randomized trial to evaluate the role of a planned, weekly phone-based nurse monitoring intervention to prevent and treat chemotherapy, targeted therapy- and immunotherapy-related toxicities. Here, we report the results from the chemotherapy arm. MethodsThis was a nationwide, randomized, open-label trial conducted among 29 Italian centers (NCT04726020) involving adult patients with breast, colon, or lung cancer and a life expectancy >= 6 months receiving adjuvant chemotherapy. Patients received either a weekly nurse monitoring phone call and an educational leaflet reporting practical advice about prevention and treatment of toxicities (experimental group) or the educational leaflet only (control group). ResultsThe addition of a nurse monitoring intervention may help reduce time spent with severe toxicities (grade >= 3), particularly those less frequently reported in clinical practice, such as fatigue. When considering grade 1-2 AEs, times with mild/moderate diarrhea, mucositis, fatigue and pain were shorter in the experimental arm. Time spent without AEs was significantly longer in the experimental arms for all the toxicities. The requirement for special medical attention was comparable between groups. ConclusionThis study suggests the need for implementing a better system of toxicity assessment and management for patients treated with adjuvant chemotherapy to promote effective preventive and/or therapeutic intervention against these events

Pre-treatment risk factors to predict early cisplatin-related nephrotoxicity in locally advanced head and neck cancer patients treated with chemoradiation: A single Institution experience

Objectives: Cisplatin is essential in the curative treatment of locally advanced head and neck squamous cell carcinoma (LA-HNSCC) patients. The assessment of risk factors to predict an early cisplatin-induced nephrotoxicity could help in better managing one of the most relevant cisplatin-related dose-limiting factors. Material and methods: We retrospectively collected data of LA-HNSCC patients treated at our Institution from 2008 to 2019. Patients received cisplatin in a curative setting concurrently with radiation. Acute Kidney Injury (AKI) was assessed as a dichotomous variable (CreaIncr) based on pre-treatment values, and values recorded at days 6-20 post-first cycle of cisplatin. Univariable logistic regression models were performed to investigate associations between CreaIncr and clinical characteristics. A multivariable logistic model on a priori selected putative covariates was performed. Results: Of the 350 LA-HNSCC treated patients, 204 were analyzed. Ninety (44 %) suffered from any grade AKI (grade I 51.1 %): out of them, 84.4 % received high-dose cisplatin (100 mg/m2 q21). On the univariable logistic regression model, male sex, age, serum uric acid, creatinine, concomitant drugs, and cisplatin schedule were significantly associated with a higher rate of AKI. At multivariable model, age (p = 0.034), baseline creatinine (p = 0.027), concomitant drugs (p = 0.043), and cisplatin schedule (one-day bolus or fractionated high-dose vs. weekly; p = 0.001) maintained their significant association. Conclusions: Identifying pre-treatment risk factors in LA-HNSCC patients may improve decision-making in a setting where cisplatin has a curative significance. A strict monitoring of AKI could avoid cisplatin dose adjustments, interruptions, and treatment delays, thus limiting a negative impact on outcomes

On the Binding Mode and Molecular Mechanism of Enzymatic Polyethylene Terephthalate Degradation

15 pages, 8 figures, supporting information https://doi.org/10.1021/acscatal.3c00259Enzymatic degradation of polyethylene terephthlate (PET) by polyester hydrolases is currently subject to intensive research, as it is considered as a potential eco-friendly recycling method for plastic waste. However, the substrate-binding mode and the molecular mechanism of enzymatic PET hydrolysis are still under intense investigation, and controversial hypotheses have been presented. To help unravel the inherent mechanism of biocatalytic PET degradation at the atomic level, we performed solid-state NMR measurements of a cutinase from Thermobifida fusca (TfCut2) embedded in trehalose glasses together with chemically synthesized, amorphous 13C(═O)-labeled oligomeric PET. The resulting ternary enzyme-PET-trehalose glassy system enabled advanced solid-state NMR methods for real-time tracking of the enzymatic PET degradation and the investigation of PET chain dynamics. Combined with enhanced-sampling molecular dynamics simulations, specific enzyme–substrate interactions during the degradation process could also be monitored. Our results demonstrate that the PET chain is first cleaved by TfCut2 in blocks of at least one repeat unit and further to terephthalic acid and ethylene glycol. Moreover, the second step (formation of final hydrolysis products) appears to be rate-limiting in such reactions. The observed dynamic changes and interfacial protein contacts of 13C-labeled PET carbonyl groups suggest that only one PET repeat unit is bound to the enzyme during the degradation process while the rest of the PET chain is only loosely confined to the active site. These results, not accessible by using conventional solution enzyme samples and small nonhydrolyzable substrates, provide a better understanding of the biocatalytic PET degradation mechanism of polyester hydrolasesP.F. was supported by a scholarship of the Deutsche Bundesstiftung Umwelt (DBU grant 20018/565).

Assessing suffering of patients on cancer treatment and of those no longer treated using ESAS-Total Care (TC)

Aim: The aim of the study was to assess the suffering of patients on oncologic treatment and of those no longer on treatment. Preliminarily, we aimed to confirm the psychometric properties of Edmonton Symptom Assessment System-Total Care (ESAS-TC) in different stages of the disease. The ESAS-TC screens physical and psychological symptoms, but also spiritual pain, discomfort deriving from financial problems associated with illness, and suffering related to social isolation. Methods: A sample of consecutive advanced cancer patients on oncologic therapies treated at the Internistic and Geriatric Supportive Care Unit (IGSCU) of Istituto Nazionale dei Tumori, Milano, and of terminal patients no longer on treatment and cared for by the Fondazione ANT palliative home care team were asked to fill the ESAS-TC. In order to strengthen the previous validation study of the ESAS-TC, 3-ULS (to assess social isolation), JSWBS (to assess spiritual well-being), COST-IT (to assess financial distress), and KPS (to assess functional status) were administered too. Results: The questionnaires were self-reported by 108 patients on treatment (52% >60 years old, female 53%, and 61% with KPS 90-100) and by 94 home care patients (71% >60 years old, female 51%, and 68% with KPS 10-50). The sound psychometric characteristics of ESAS-TC were confirmed. Patients on treatment showed lower total ESAS-TC score (19.3 vs 52.7, p<.001) after controlling for age and functional status, and lower financial distress (p.<001). Financial distress, spiritual suffering, and social isolation, after controlling for age, showed a significantly higher score in home care patients. Conclusions: Only through an adequate routine assessment with validated tools is it possible to detect total suffering, the "Total pain" of patients, and treat it through a multidisciplinary approach. The study confirms the reliability and validity of the Italian version of ESAS-TC and the importance of supportive and early palliative care fully integrated with oncological treatment

Cognitive Decline in Older Long-Term Survivors From Non-Hodgkin Lymphoma: A Multicenter Cross-Sectional Study

Objectives: To compare cognition in a group of older long-term survivors from Non-Hodgkin Lymphoma (NHL) and in a corresponding group of non-cancer controls of the same age. Functional status, polypharmacy and multimorbidity were also evaluated. Methods: A cross-sectional study was performed in a population of 63 outpatient long-term survivors from NHL, aged 65 or more and 61 non-cancer controls. Socio-demographic, clinical and functional data were collected. Cognitive function was assessed through neuropsychological tests. Results: NHL survivors showed a slightly worse functional status than controls, they were affected by more chronic conditions (3.4 vs 2.3; p = .003) and were taking a higher number of medications (3.4 vs 2.3; p = .03). The Mini Mental State Examination (MMSE) was not significantly different between the groups. NHL survivors performed worse than controls in executive functioning (Trail Making Test B-A 47.9 vs 32.1 p = .04, OR for Stroop test time over 75th percentile in survivors: 2.66; CI 95% 1.04-6.61; OR for Multiple Features Target Cancellation time over 75th percentile in survivors: 2.84; CI 95% 1.10-7.31). A small, statistically significant difference was also observed in verbal memory scores between the two groups. . Conclusions: The findings of this study suggest that, compared with non-cancer controls, older survivors from NHL may have a lower cognitive performance, especially in the executive functioning and attention domains, regardless of multimorbidity and polypharmacy. Further evidence from larger samples is needed to confirm such findings and better characterize cognitive decline in NHL survivors
