The Relationship between Tumor Development and Sarcoidosis in Aspects of Carcinogenesis before and after the Onset of Sarcoidosis.

Background and Objectives: It is still unclear whether sarcoidosis is likely to be associated with tumors. In addition, the use of an immune checkpoint inhibitor has been reported to initiate the onset of sarcoidosis. We retrospectively analyzed tumor development before and after the diagnosis of sarcoidosis and examined the impact of having a history of tumors on the activity or the severity of sarcoidosis. Materials and Methods: We recruited 312 consecutive cases of sarcoidosis and analyzed the tumor development before and after the onset of sarcoidosis. Results: Among them, 25 cases were diagnosed with malignant tumor after diagnosis of sarcoidosis. In the analysis of the tumor-development group after diagnosis of sarcoidosis, both serum angiotensin I-converting enzyme and mediastinal lymph node size were significantly reduced at the time of malignant tumor diagnosis compared to at the onset of sarcoidosis, indicating that the decreasing activity of sarcoidosis may be partly associated with tumor development. Furthermore, we examined 34 cases having tumor history before the onset of sarcoidosis and analyzed the effect of tumor history on the severity of sarcoidosis. Cases with a malignant tumor in the past were older and had less complicated organs of sarcoidosis than cases without malignant tumors in the past. Oral corticosteroid therapy was administrated more frequently in cases without malignant tumors in the past, indicating that the history of a malignant tumor may influence the severity of sarcoidosis. Conclusion: These results indicate that tumor development may be partly associated with the activity or severity of sarcoidosis.

Administration of docetaxel plus ramucirumab with primary prophylactic pegylated-granulocyte colony-stimulating factor for pretreated non-small cell lung cancer: a phase II study.

PURPOSE: Although docetaxel plus ramucirumab has shown superior treatment efficacy over docetaxel monotherapy for patients with non-small cell lung cancer (NSCLC), the high rate of febrile neutropenia (FN) presents a clinical problem. This study aimed to validate the primary prophylactic use of pegfilgrastim with docetaxel and ramucirumab treatment in Japanese patients with NSCLC. METHODS: Patients with NSCLC with progression after at least one round of chemotherapy were enrolled and administered docetaxel (60 mg/m2) plus ramucirumab (10 mg/kg) intravenously on day 1, followed by pegylated-granulocyte colony-stimulating factor (3.6 mg) on day 2 of a 21-day treatment cycle. The primary study endpoint was the percentage of patients who developed FN. Secondary endpoints included overall survival, progression-free survival, overall response rate, and safety. RESULTS: Overall, 20 patients (15 men and 5 women) were enrolled, of whom one developed FN, resulting in an overall FN rate of 5%. The response and disease control rates were 40% and 85%, respectively. The median progression-free survival was 6.6 (95% confidence interval [CI], 0.5-NR) months. The median overall survival was 18.4 (95% CI, 2.2-11.0) months. Six patients aged over 75 years were included in this study, and although most adverse events were durable, ramucirumab-associated adverse events occurred more frequently in these patients. CONCLUSIONS: We observed a 5% FN rate using primary prophylactic pegylated-granulocyte colony-stimulating factor with docetaxel plus ramucirumab in Japanese patients with NSCLC. While most adverse events were durable, elderly patients should be closely monitored.

Predictors of Discontinuance of Oral Feeding in Patients With Advanced Alzheimer Dementia and Aspiration Pneumonia in Japan: A Single-center, Retrospective Observational Study.

BACKGROUND: Difficulty with oral feeding, the most commonly observed complication of Alzheimer disease (AD) in its final stages, occurs in 86% of AD patients and may prevent achievement of oral feeding after aspiration pneumonia. However, no reliable indicators of discontinuance of oral feeding have yet been identified. We therefore aimed to identify predictors of discontinuance of oral feeding in postaspiration pneumonia patients with AD. MATERIALS AND METHODS: Relevant clinical and laboratory data of 60 patients with AD admitted to our hospital in Japan for aspiration pneumonia were retrospectively compared between oral feeding and discontinuance groups. RESULTS: The study groups differed in interval since diagnosis of AD, CURB-65 score, pneumonia severity index score, and proportion of patients who died (higher in the discontinuance group) and body mass index (BMI), Mini Mental State Examination (MMSE) score, and functional independence measure score (lower in the discontinuance group). According to multivariate logistic regression analysis of all identified independent variables, only CURB-65 and MMSE scores and BMI are significant predictors of discontinuance of oral feeding after aspiration pneumonia in patients with advanced AD. CONCLUSIONS: In patients with advanced AD, discontinuance of oral feeding after aspiration pneumonia may be predicted by CURB-65 and MMSE scores and BMI.

Liver Cirrhosis and Hepatocellular Carcinoma Diagnosed from Chylothorax: A Case Report.

A 71-year-old man visited our hospital with dyspnea and left pleural effusion. Left pleural effusion was diagnosed as chylothorax by thoracentesis. He had no history of trauma or surgery, and there were no findings of malignant lymphoma or thrombosis. Furthermore, he was diagnosed with liver cirrhosis and hepatocellular carcinoma by computed tomography and hematological examinations, and the chylothorax was considered to be caused by liver cirrhosis. We report a review of the literature with this case since it is relatively rare for cirrhosis and hepatocellular carcinoma diagnosed from chylothorax.
