A text-mining approach to study the real-world effectiveness and potentially fatal immune-related adverse events of PD-1 and PD-L1 inhibitors in older patients with stage III/IV non-small cell lung cancer.

BACKGROUND: This study was designed to investigate the impact of age on the effectiveness and immune-related adverse events (irAEs) of programmed death-(ligand)1 [PD-(L)1] inhibitors in patients with non-small cell lung cancer (NSCLC) using a novel text-mining technique. METHODS: This retrospective study included patients with stage III/IV NSCLC treated with a PD-(L)1 inhibitor (nivolumab, pembrolizumab, atezolizumab and durvalumab) at Leiden University Medical Centre and Haga Teaching hospital, (both in The Netherlands) from September 2016 to May 2021. All the relevant data was extracted from the structured and unstructured fields of the Electronic Health Records using a novel text-mining tool. Effectiveness [progression-free survival (PFS) and overall survival (OS)] and safety (the incidence of nine potentially fatal irAEs and systemic corticosteroid requirement) outcomes were compared across age subgroups (young: < 65 years, Middle-aged: 65-74 years, and old: ≥ 75 years) after adjustment for confounding. RESULTS: Of 689 patients, 310 patients (45.0%) were < 65 years, 275 patients (39.9%) were aged between 65 and 74 years, and 104 patients (15.1%) were ≥ 75 years. There was no significant difference between younger and older patients regarding PFS (median PFS 12, 8, 13 months respectively; Hazard ratio (HR)middle-aged = 1.14, 95% CI 0.92-1.41; HRold = 1.10, 95% CI 0.78-1.42). This was also the case for OS (median OS 19, 14, 18 months respectively; HRmiddle-aged = 1.22, 95% CI 0.96-1.53; HRold = 1.10, 95% CI 0.79-1.52). Safety analysis demonstrated a higher incidence of pneumonitis among patients aged 65-74. When all the investigated irAEs were pooled, there was no statistically significant difference found between age and the incidence of potentially fatal irAEs. CONCLUSIONS: The use of PD-(L)1 inhibitors is not associated with age related decrease of PFS and OS, nor with increased incidence of serious irAEs compared to younger patients receiving these treatments. Chronological age must therefore not be used as a predictor for the effectiveness or safety of ICIs.

Evaluation and Implementation of ListeningTime: A Web-Based Preparatory Communication Tool for Elderly Patients With Cancer and Their Health Care Providers.

BACKGROUND: Effective patient-provider communication is an important condition to deliver optimal care and it supports patients in coping with their disease. The complex and emotionally loaded setting of oncology care challenges both health care providers (HCPs) and patients in reaching effective communication. ListeningTime is developed for elderly patients with cancer and their oncological HCPs to help them (better) prepare the clinical encounter and overcome communication barriers. ListeningTime is a Web-based preparatory communication tool including modeling videos and has an audio-facility to listen back to recorded encounters. OBJECTIVE: This study aims to evaluate the usability, perceived usefulness, and actual use of ListeningTime, through the eyes of elderly patients with cancer and their oncological HCPs. If highly rated, the ultimate goal is to make ListeningTime publicly available. METHODS: First, members of a panel of elderly cancer survivors and patients (age ≥65 years) were approached to evaluate ListeningTime through a Web-based questionnaire. The usability and perceived usefulness were assessed. Second, ListeningTime was evaluated in real-life practice through a pilot study in 3 Dutch hospitals. In these hospitals, elderly patients with cancer and their oncological HCPs were approached to evaluate ListeningTime through a similar Web-based questionnaire, measuring the perceived usefulness. In addition, we examined log files and user statistics to get insight into how the program was used. RESULTS: A total of 30 cancer survivors or patients from the patient panel, and 17 patients and 8 HCPs from the hospitals, evaluated ListeningTime. Overall, both panel members and hospital patients were positive about the ListeningTime website, audio-facility, and video fragments. Some patients suggested improvements with respect to the actors' performances in the video fragments and believed that ListeningTime is mainly suitable for non experienced patients. HCPs were also positive about ListeningTime; they valued the video fragments for patients and the audio-facility for patients and themselves. However, providers did not relisten their own recorded encounters. Patients did use the audio-facility to relisten their encounters. CONCLUSIONS: ListeningTime was highly rated, both by patients and their oncological HCPs. As a result, the video fragments of ListeningTime are now made publicly available for elderly patients with cancer through the Dutch website "kanker.nl."

Effects of controlled ovarian stimulation on toxicity of TAC chemotherapy in early breast cancer patients.

BACKGROUND: Oocyte and embryo cryopreservation, using controlled ovarian stimulation (COS), are common fertility preservation methodologies in breast cancer patients receiving gonadotoxic neo (adjuvant) chemotherapy (CT). The effects of COS and peak estradiol levels on CT-induced side effects are unknown. PATIENTS AND METHODS: Eighteen patients with stage II and III breast cancer underwent oocyte or embryo cryopreservation at Leiden University Medical Center before receiving docetaxel, adriamycin, and cyclophosphamide (TAC) CT (COS group). A control group (N=18) was retrospectively selected from breast cancer patients, aged between 18 and 40, who underwent TAC CT without fertility preservation. CT -induced toxicity in the 2 groups was compared using χ2 analysis. Associations between peak estradiol levels and distinct stimulation protocols and side effects in the COS group were investigated by using regression analysis. RESULTS: Patient characteristics between both groups were similar, except for a lower age in the COS group vs the control group (30.5 vs 35.2 years, P=0.005). No differences were seen in grade III/IV side effects between both groups. In the COS group, an increase in thrombopenia grade I/II was seen, while grade I/II stomatitis and constipation were significantly lower in the COS group as compared with the control group (P=0.006 and P=0.008, respectively). In the COS group, no association was found between the peak estradiol levels and distinct stimulation protocols and side effects of CT. CONCLUSION: COS prior to TAC CT was not associated with an increase in grade III/IV side effects. Interestingly, COS may have a protective effect on mucositis and constipation. Moreover, the peak estradiol levels and distinct stimulation protocols had no effect on grade III/IV side effects in our study.
