Durvalumab after chemoradiotherapy for locoregional recurrence of completely resected non-small-cell lung cancer (NEJ056).

Locoregional recurrence of non-small-cell lung cancer (NSCLC) after complete resection lacks standard treatment. Durvalumab after chemoradiotherapy (CRT) or CRT alone is often selected in daily clinical practice for patients with locoregional recurrence; however, the therapeutic efficacy of these treatments remains unclear, and we aimed to assess this. This retrospective observational study used data from patients with NSCLC diagnosed with locoregional recurrence after complete resection who subsequently underwent concurrent CRT followed by durvalumab (CRT-D group) or CRT alone (CRT group). We employed propensity score analysis with inverse probability treatment weighting (IPTW) to adjust for various confounders and evaluate efficacy in the CRT-D group. After IPTW adjustment, the CRT-D group contained 119 patients (64.7% male; 69.7% adenocarcinoma), and the CRT group contained 111 patients (60.5% male; 73.4% adenocarcinoma). Their mean ages were 66 and 65 years, respectively. The IPTW-adjusted median progression-free survival was 25.4 and 11.5 months for the CRT-D and CRT groups, respectively (hazard ratio, 0.44; 95% confidence interval, 0.30-0.64); the median overall survival was not reached in either group favoring CRT-D (hazard ratio, 0.49; 95% confidence interval, 0.24-0.99). Grade 3 or 4 adverse events were observed in 48.8% of patients during CRT, 10.7% after initiating durvalumab maintenance therapy in the CRT-D group, and 57.3% in the CRT group. Overall, the sequential approach of CRT followed by durvalumab is a promising treatment strategy for locoregional recurrence of NSCLC after complete resection.

Herpes Simplex Virus Encephalitis after Recovery from Coronavirus Disease 2019: A Rare Case Report.

An 85-year-old woman was diagnosed with coronavirus disease 2019 (COVID-19). The patient was treated with dexamethasone, and the infection was cured. She later developed a low-grade fever and fell unconscious. Positivity for herpes simplex virus deoxyribonucleic acid polymerase chain reaction (HSV-DNA PCR) was detected in the cerebrospinal fluid, so she was diagnosed with HSV encephalitis. The patient was treated with antiviral drugs and recovered from the HSV encephalitis. This case suggests that, in patients with COVID-19 and disorders of consciousness, the possibility of HSV encephalitis should be considered along with COVID-19 encephalitis.

Evaluating the potential of immunotherapy and chemoimmunotherapy in the treatment of elderly non-small cell lung cancer patients: A real-world study.

BACKGROUND: Immune checkpoint inhibitor (ICI) has become the standard therapy for metastatic non-small cell lung cancer (NSCLC) patients. However, no robust evidence on the efficacy and safety of ICI in elderly NSCLC patients has been established. MATERIALS AND METHODS: This retrospective study aimed to assess the efficacy and safety of ICI in elderly NSCLC patients. NSCLC patients treated with ICI monotherapy or chemoimmunotherapy (CIT) between 2016 and 2022 were divided into two cohorts according to the age: the Elderly cohort (patients aged ≥ 75 years) and the Nonelderly cohort (patients aged < 75 years). The progression-free survival (PFS), tumor response, and frequency of immune-related adverse events (irAEs) were compared between the two cohorts. RESULTS: A total of 111 NSCLC patients were included in this study (41 patients in the Elderly cohort and 70 patients in the Nonelderly cohort). The PFS (5.6 months vs. 6.3 months, P = 0.98), response rate (36.6% vs. 44.9%, P = 0.51), and disease control rate (80.5% vs. 76.8%, P = 0.83) were not significantly different between the two cohorts. In a subgroup analysis, stratified according to PD-L1 expression (low vs. high) and ICI treatment mode (ICI monotherapy vs. CIT), the PFSs of both cohorts were also not significantly different, regardless of PD-L1 expression. Moreover, the frequency of irAEs did not significantly differ between elderly and nonelderly NSCLC patients (21/41 [51.2%] vs. 38/70 [54.3%], P = 0.91). CONCLUSION: The efficacy and safety of ICI in elderly NSCLC patients were not inferior to those in younger patients.
