Abstract Background Although the incidence of lung cancer in elderly individuals has been increasing in recent years, the number of clinical trials designed specifically for elderly patients with advanced non‐small cell lung cancer (NSCLC) is still limited. To fulfill this unmet medical need, we conducted a phase II study to elucidate the efficacy of pemetrexed (PEM) plus bevacizumab (Bev) combination chemotherapy in elderly patients with nonsquamous NSCLC. Methods A total of 29 elderly patients (≥75 years old) with nonsquamous NSCLC were enrolled in this multicenter, open‐label, phase II study, and 27 patients were finally analyzed. PEM at 500 mg/m2 on day 1 plus Bev at 15 mg/kg on day 1 were administered triweekly. The primary endpoint was the investigator‐assessed objective response rate. Results The median age at initiating chemotherapy was 80 years old. Almost all patients (92.6%) had adenocarcinoma histology. The median number of cycles administered was 6, and the objective response rate was 40.7%. The median progression‐free survival, overall survival and 1‐year survival were 8.8 months, 27.2 months and 79%, respectively. The treatment was well‐tolerated, and no treatment‐related death was observed. Conclusion Combination chemotherapy with PEM plus Bev in elderly patients with previously untreated advanced non‐squamous NSCLC exhibited favorable antitumor activity and tolerability, suggesting that a combination of PEM plus Bev might be a promising treatment option for this population.

Severe fever with thrombocytopenia syndrome (SFTS) is a bunyavirus infection with high mortality. Favipiravir has shown effectiveness in preventing and treating SFTS virus (SFTSV) infection in animal models. A multicenter non-randomized, uncontrolled single arm trial was conducted to collect data on the safety and the effectiveness of favipiravir in treatment of SFTS patients. All participants received favipiravir orally (first-day loading dose of 1800 mg twice a day followed by 800 mg twice a day for 7-14 days in total). SFTSV RT-PCR and biochemistry tests were performed at designated time points. Outcomes were 28-day mortality, clinical improvement, viral load evolution, and adverse events (AEs). Twenty-six patients were enrolled, of whom 23 were analyzed. Four of these 23 patients died of multi-organ failure within one week (28-day mortality rate: 17.3%). Oral favipiravir was well tolerated in the surviving patients. AEs (abnormal hepatic function and insomnia) occurred in about 20% of the patients. Clinical symptoms improved in all patients who survived from a median of day 2 to day10. SFTSV RNA levels in the patients who died were significantly higher than those in the survivors (p = 0.0029). No viral genomes were detectable in the surviving patients a median of 8 days after favipiravir administration. The 28-day mortality rate in this study was lower than those of the previous studies in Japan. The high frequency of hepatic dysfunction as an AE was observed. However, it was unclear whether this was merely a side effect of favipiravir, because liver disorders are commonly seen in SFTS patients. The results of this trial support the effectiveness of favipiravir for patients with SFTS.

Objectives We conducted a subanalysis of data from the multicentre, retrospective observational Nivolumab Japan Real World (CA209-9CR) study to evaluate nivolumab effectiveness and safety in elderly patients (aged ≥75 years) with advanced/metastatic non-small cell lung cancer.Materials and methods Medical record data of patients initiating nivolumab treatment between April 2016 and December 2016 were collected using electronic data capture from 23 cancer hospitals in Japan between March 2017 and August 2018. Nivolumab treatment data were collected to investigate the treatment patterns by age group (

We report the case of a 76-year-old woman who was referred to our hospital for a gradually worsening cough and renal dysfunction. Although pneumonia was initially suspected, imaging findings of the lungs revealed diffuse alveolar hemorrhage at a later date. Renal failure developed and hemodiafiltration was performed on the 9th day. Rapidly progressive glomerulonephritis with crescent formation was diagnosed by renal biopsy. This case presentation has important clinical implications because uncategorizable pulmonary-renal syndrome (PRS) without the presence of ANCAs and anti-GBM antibody is extremely rare and has high rates of morbidity and mortality. No treatment has been established.
