Purpose: For patients with germ cell cancer, various pulmonary toxicity risk factors have been hypothesized for treatment with bleomycin, etoposide, and cisplatin (BEP). Because existing studies have shortcomings, we present a large, unselected cohort of patients who have undergone close monitoring of lung function before, during, and after treatment with BEP to disclose valid pulmonary toxicity risk factors. Patients and Methods: All patients who were treated with BEP at Rigshospitalet, Copenhagen, Denmark, from 1984 to 2007, were included. Pulmonary function tests (PFTs) that measured the diffusing capacity of the lungs for carbon monoxide (DL_CO), forced expiratory volume in 1 second, and forced vital capacity were performed systematically before, during, and after treatment with BEP for 5 years of follow-up. According to local protocol, bleomycin was discontinued if hemoglobin-corrected DL_CO (DL_COc) decreased ≥ 25% compared with pretreatment value. Covariates of possible importance were evaluated with a multiple regression analysis for pretreatment PFTs and with a mixed model for follow-up PFTs. Bleomycin was adjusted on the basis of PFT results and was thus omitted as covariate. Results: Overall, 565 patients were evaluated with a PFT before or after treatment with BEP. During BEP, 15 patients died of progressive disease or toxicity, including one patient from bleomycin-induced pneumonitis. Post-treatment DL_COc decreased significantly, with a rebound during follow-up. Forced expiratory volume in 1 second and forced vital capacity remained unchanged after BEP but increased significantly to levels above pretreatment during follow-up. International Germ Cell Cancer Collaborative Group (IGCCCG) prognostic group, mediastinal primary, pulmonary metastases, and smoking all significantly influenced baseline PFT results. Pulmonary surgery, pulmonary embolism, IGCCCG poor prognosis, and smoking influenced PFT during follow-up. Mediastinal primary, pulmonary metastases, age, or doses of cisplatin and etoposide had no influence on follow-up PFT, and renal function did not influence PFT. Conclusion: After 5 years of follow-up, pulmonary impairment in patients with germ cell cancer who were treated with BEP was limited. Exceptions were patients treated with pulmonary surgery, those who suffered pulmonary embolism, and those in the IGCCCG poor prognostic group.

Background The selection of patients with non-small cell lung cancer (NSCLC) for immune checkpoint inhibitor (ICI) treatment remains challenging. This real-world study aimed to compare the overall survival (OS) before and after the implementation of ICIs, to identify OS prognostic factors, and to assess treatment data in first-line (1L) ICI-treated patients without epidermal growth factor receptor mutation or anaplastic lymphoma kinase translocation. Methods Data from the Danish NSCLC population initiated with 1L palliative antineoplastic treatment from 1 January 2013 to 1 October 2018, were extracted from the Danish Lung Cancer Registry (DLCR). Long-term survival and median OS pre- and post-approval of 1L ICI were compared. From electronic health records, additional clinical and treatment data were obtained for ICI-treated patients from 1 March 2017 to 1 October 2018. Results The OS was significantly improved in the DLCR post-approval cohort (n = 2055) compared to the pre-approval cohort (n = 1658). The 3-year OS rates were 18% (95% CI 15.6–20.0) and 6% (95% CI 5.1–7.4), respectively. On multivariable Cox regression, bone (HR = 1.63) and liver metastases (HR = 1.47), performance status (PS) 1 (HR = 1.86), and PS ≥ 2 (HR = 2.19) were significantly associated with poor OS in ICI-treated patients. Conclusion OS significantly improved in patients with advanced NSCLC after ICI implementation in Denmark. In ICI-treated patients, PS ≥ 1, and bone and liver metastases were associated with a worse prognosis.

Treatment with bleomycin-etoposide-cisplatin (BEP) impairs renal function and increases the risk of late cardiovascular disease (CVD) and death. We investigated the influence of BEP on glomerular filtration rate (GFR) and assessed the importance of GFR changes on CVD and death in a large cohort of germ-cell cancer survivors. BEP-treated patients (N = 1206) were identified in the Danish DaTeCa database, and merged with national registers to identify late toxicity. GFR were measured (51Cr-EDTA clearance) before and after treatment and at 1, 3 and 5-year follow-up. The influence of BEP on GFR was evaluated with a linear mixed model. Risk factors for late toxicity were identified by a landmark analysis adjusting for covariates. The cohort was compared with the background population with standardized hospitalization/mortality rates. GFR changed (ΔGFR) -11.3%, -15.4% and -25.9% after three, four and five+ cycles of BEP. For patients with impaired renal function before treatment the changes were 4.3%, 0.0% and -12.8%, respectively. During follow-up a significant rebound of GFR was documented. Compared with the background population, all patients, irrespective of renal function, had an increased risk of CVD and death. This risk depended on chronic kidney disease stage before treatment but not after treatment. ΔGFR had no influence on risk of late toxicity [death: hazard ratio (HR) 1.06, P = 0.50; CVD: HR 0.97, P = 0.61]. Renal function after BEP is closely related to number of cycles, but the changes in GFR are partly reversible and have no impact on risk of CVD or death.

, Anesthesia & Analgesia, British Journal of Anesthesia, Anesthesia, and Acta Anaesthesiologica Scandinavica from January to June, 2000. Articles were assessed and classified according to type, outcome, and design; 1379 articles consisting of 5468 pages were evaluated and categorized. The most common types of article were animal and laboratory research (31.2%) and randomized clinical trial (20.4%). A clinically relevant article was defined as an article that used a statistically valid method and had a clinically relevant end-point. Altogether 18.6% of the pages had as their subject matter clinically relevant trials. We compared the Journal Impact Factor (a measure of the number of citations per article in a journal) and the proportion of clinically relevant pages and found that they were inversely proportional to each other....
