Background: Antiangiogenic agents have been shown to stimulate the immune system and cause synergistic effects with chemotherapy. Effects might be even stronger after immune-checkpoint-inhibitor (ICI) therapy. The purpose of this analysis was to evaluate the efficacy of ramucirumab plus docetaxel (R + D) as third-line treatment after failure of a first-line platinum-based chemotherapy and a second-line ICI treatment in patients with non-small-cell lung cancer (NSCLC) stage IV. Methods: Retrospective data were collected from 9 German thoracic oncology centers. Only patients who had received at least 1 cycle of third-line R + D were included. The numbers of cycles, objective response rate (ORR), progression-free survival (PFS), and overall survival (OS) were investigated. Results: Sixty-seven patients met the criteria for inclusion. Third-line treatment with R + D achieved an ORR of 36% and a disease control rate (DCR) of 69%. Median PFS for third-line therapy was 6.8 months with a duration of response (DOR) of 10.2 months. A median OS of 29 months was observed from the start of first-line therapy with a median OS of 11.0 months from the start of third-line treatment. No unexpected toxicities occurred. Conclusion: R + D is a highly effective and safe third-line treatment after failure of second-line programmed cell death protein 1/programmed cell death-ligand 1 (PD1/PD-L1)-derived ICI therapy irrespective of NSCLC histology. As there may be synergistic effects of second- and third-line treatments, this sequence is a very suitable option for patients not treated with first-line ICI. In addition, R + D should continue to be investigated as a second-line treatment option after failure of chemotherapy plus ICI in the palliative first–line treatment. [ABSTRACT FROM AUTHOR]

Due to the importance of arousals for the interpretation of sleep wake disturbances, origin and meaning, methodological aspects and clinical relevance are discussed. There exist multiple entero- and exteroceptive arousal stimuli followed by EEG, autonomic and behavioral arousals. Also in pediatric sleep medicine the analysis of arousals is of great importance, because disturbances of the arousal mechanism can play a causal role for life threatening events or daytime somnolence. Despite clear criteria for the diagnosis of arousals (ASDA) there exists a certain interrater variability leading to different evaluation of sleep fragmentation. Automatic computer analysis offers no alternative: the results should always be controlled and eventually corrected by trained experts. In the last years the detection rate of respiratory events with consecutive EEG arousals was improved by non invasive methods as measurement of pressure with nasal prongs, impedance or effort/phase angle. The registration of pulse- transit-time and continously measured blood pressure allows to quantify autonomic arousals. By examples of different diseases as obstructive sleep apnea, central sleep apnea, chronic obstructive lung disease, periodic movement during sleep, psychophysiological insomnias, epilepsy, parasomnias and hypersonmias the effects of arousals are discussed. Additionally to arousals further... [ABSTRACT FROM AUTHOR]

Background: Chemotherapy plus immune-checkpoint inhibitor (CTx+ICI) therapy has become the preferred 1st line treatment in patients with metastatic NSCLC without oncogenic driven mutations. However, the optimal subsequent 2nd line treatment is not defined and several alternatives exist. The purpose of this analysis was to evaluate the efficacy of 2nd line docetaxel plus ramucirumab (D+R) initiated after failure of 1st line CTx+ICI., Methods: Retrospective data were collected during routine care from German thoracic oncology centers. Only patients who had received at least one course of 2nd line D+R were included. ORR, PFS, OS and numbers of courses of D+R were investigated with PFS after initiation of D+R being the primary endpoint., Results: Seventy-seven patients met the inclusion criteria. 2nd line treatment with D+R achieved an ORR and DCR of 32.5% and 62.4%, respectively. Median PFS for 2nd line therapy was 3.9 months with a DOR of 6.4 months. Median OS of 15.5 and 7.5 months were observed from the start of 1st line therapy and 2nd line treatment, respectively. No unexpected toxicities occurred. Presence of KRAS mutations was associated with significantly worse median PFS to D+R (2.8 vs. 4.5 months in wild-type cases; P=0.021) and was an independent predictor of inferior PFS in multivariate analysis., Conclusions: D+R is an effective and safe 2nd line treatment after failure of 1st line CTx+ICI irrespective of NSCLC histology. However, patients with a KRAS mutation did not benefit from D+R in terms of PFS and will require further investigations., Competing Interests: Conflicts of Interest: All authors have completed the ICMJE uniform disclosure form (available at https://dx.doi.org/10.21037/tlcr-21-197).

Background: Prognostic and predictive factors of routine clinical practice among patients with small cell lung carcinoma (SCLC) were evaluated., Patients and Methods: Data from 106 patients with SCLC treated by first-line adriamycin, cyclophosphamide and etoposide (ACE) chemotherapy were analyzed. Multivariate analysis was performed., Results: The median overall survival (mOS) of patients was 9.36 months with mOS of 31%, 8% and 3% after 1, 2 and 5 years, respectively. Using multivariate analysis ECOG performance status (p =0.008) and white blood count (WBC) (p=0.022) were independent prognostic factors for mOS. With both, three groups of outcome (good, intermediate, poor) resulting in mOS of 15.8 months, 6.87 months and 3.35 months (p<0.0001) could be established, respectively. The absence of brain metastases (p=0.002), dose reduction (p=0.002) and LDH value (p=0.017) were independent predictive markers. Additionally, female gender was predictive (p=0.025) for complete response (CR)., Conclusion: Patients with a poor prediction profil might not benefit from ACE chemotherapy. As a consequence, prognostic/predictive factors should be included as stratification criteria in prospective clinical studies.

Study Objectives: To investigate the frequency of microarousals (MA) associated with pressure changes during auto-CPAP therapy (APAP) for obstructive sleep apnea (OSA)., Design: Patients with OSA were studied by polysomnography during APAP therapy (Somnosmart). The MA were classified on the basis of concomitant changes in APAP pressure., Setting: Sleep laboratory of a university hospital, Participants: 30 patients with moderate to severe OSA., Measurements and Results: The mean AHI during APAP was 4.7+/-4.7, the mean arousal index was 14.5+/-6.6 per hour. During epochs with a pressure variation greater than 0.5 mbar, significantly more MA occurred (0.30+/-0.17 MA per epoch) than in epochs with constant treatment pressure (0.10+/-0.054 MA per epoch; p<0.001). There were more MA during pressure-increase epochs than during pressure-decrease epochs (0.42+/-0.24 vs. 0.16+/-0.12 MA per epoch; p<0.001). 82.5 percent of the MA were not preceded by a significant change in pressure (at least 0.5 mbar within 30 sec.), 10.6% were associated with a significant prior increase and 6.9% with a significant prior decrease in pressure. The percentage of MA preceded by a significant pressure variation varied between 2.3% and 61%, with a mean of 18.9%., Conclusions: The overall frequency of MA was low, and in most individuals the relative amount of "pressure-associated MA" was not significant. However in some individuals it cannot be excluded that some additional MA may have been induced by pressure variations. Should it prove possible to prevent such "pressure-associated MA" by optimizing the regulation of APAP pressure, the overall clinical effect of APAP treatment may be improved.
