The aim of this study was to update a previous scoring system for patients with skeletal metastases, that was proposed by Katagiri et al. in 2005, by introducing a new factor (laboratory data) and analyzing a new patient cohort. Between January 2005 and January 2008, we treated 808 patients with symptomatic skeletal metastases. They were prospectively registered regardless of their treatments, and the last follow-up evaluation was performed in 2012. There were 441 male and 367 female patients with a median age of 64 years. Of these patients, 749 were treated nonsurgically while the remaining 59 underwent surgery for skeletal metastasis. A multivariate analysis was conducted using the Cox proportional hazards model. We identified six significant prognostic factors for survival, namely, the primary lesion, visceral or cerebral metastases, abnormal laboratory data, poor performance status, previous chemotherapy, and multiple skeletal metastases. The first three factors had a larger impact than the remaining three. The prognostic score was calculated by adding together all the scores for individual factors. With a prognostic score of ≥7, the survival rate was 27% at 6 months, and only 6% at 1 year. In contrast, patients with a prognostic score of ≤3 had a survival rate of 91% at 1 year, and 78% at 2 years. Comparing the revised system with the previous one, there was a significantly lower number of wrongly predicted patients using the revised system. This revised scoring system was able to predict the survival rates of patients with skeletal metastases more accurately than the previous system and may be useful for selecting an optimal treatment.

Among galectin family members, galectin-9 was first described as a potent eosinophil chemoattractant derived from Ag-stimulated T cells. In the present study a role of galectin-9 in the interaction between eosinophils and fibroblasts was investigated using a human lung fibroblast cell line, HFL-1. RT-PCR, real-time PCR, and Western blot analyses revealed that both galectin-9 mRNA and protein in HFL-1 cells were up-regulated by IFN-γ stimulation. On the one hand, IL-4, known as a Th2 cytokine, did not affect the galectin-9 expression in HFL-1 cells. We further confirmed that IFN-γ up-regulated the expression of galectin-9 in primary human dermal fibroblasts. Flow cytometric analysis revealed that IFN-γ up-regulated surface galectin-9 expression on HFL-1 cells. Stimulation of HFL-1 cells with IFN-γ up-regulated adhesion of eosinophils, but not neutrophils, to HFL-1 cells. This adherence of eosinophils to HFL-1 cells was inhibited by both lactose and anti-galectin-9 Ab. These findings demonstrate that IFN-γ-induced galectin-9 expression in fibroblasts mediates eosinophil adhesion to the cells, suggesting a crucial role of galectin-9 in IFN-γ-stimulated fibroblasts as a physiological modulator at the inflammatory sites.

RT with 30 Gy in 10 fractions is an adequate treatment for bleeding from advanced gastric cancer, especially in patients with poor prognosis.

Introduction The epidemic of coronavirus disease 2019 (COVID-19) rapidly spread worldwide, and the various infection control measures have a significant influence on the spread of many infectious diseases. However, there have been no multicenter studies on how the number of hospitalized children with various infectious diseases changed before and after the outbreak of COVID-19 in Japan. Methods We conducted a multicenter, prospective survey for hospitalized pediatric patients in 18 hospitals in Hokkaido Prefecture, Japan, from July 2019 to February 2021. We defined July 2019 to February 2020 as pre-COVID-19, and July 2020 to February 2021 as post-COVID-19. We surveyed various infectious diseases by sex and age. Results In total, 5,300 patients were hospitalized during the study period. The number of patients decreased from 4,266 in the pre-COVID-19 period to 701 (16.4%) post-COVID-19. Patients with influenza and RSV decreased from 308 and 795 pre-COVID-19 to zero and three (0.4%) post-COVID-19. However, patients with adenovirus (respiratory infection) only decreased to 60.9% (46 to 28) of pre-COVID levels. Patients with rotavirus, norovirus, and adenovirus gastroenteritis decreased markedly post-COVID-19 to 2.6% (38 to 1), 27.8% (97 to 27) and 13.5% (37 to 5). The number of patients with UTIs was similar across the two periods (109 and 90). KD patients decreased to 31.7% (161 to 51) post-COVID-19. Conclusions We suggest that current infection control measures for COVID-19 such as wearing masks, washing hands, and disinfecting hands with alcohol are effective against various infectious diseases. However, these effects vary by disease.

The study was performed to evaluate radiotherapy for patients with intramedullary spinal cord metastasis (ISCM) and to identify the clinical features of ISCM. The subjects were 18 patients (8 men, 10 women) with ISCM who underwent radiotherapy between September 2002 and February 2008. The primary lesions were lung cancer in 8 patients (2 small cell, 6 non-small cell), breast cancer in 6, malignant melanoma in 2, renal cell carcinoma in 1, and rectal cancer in 1 patient. Diagnosis, symptoms and survival of these patients were compared with those for 544 patients with vertebral metastases who underwent radiotherapy at the same institute between September 2002 and November 2006. In the 18 patients with ISCM, the 6-month survival rate after radiotherapy was 36% and the median survival period was 4.0 months. Ten patients had neurological improvement or pain relief after radiotherapy. Brain metastases were six fold more frequent in the patients with ISCM than in those with vertebral metastasis [89% vs. 15%, p = 0.001]. At the time of radiotherapy, back pain in patients with vertebral metastasis was more frequent [97% vs. 33%, p = 0.001] but neurological deficits were less common [24% vs. 100% , p = 0.001]. Most ISCM cases were diagnosed by contrast-enhanced MRI, with detection by contrast-enhanced CT in only 3/18 cases (17%). ISCM has a poor prognosis and most patients have neurological deficits that impair quality of life. Early diagnosis by MRI is important for suspected ISCM to allow initiation of radiotherapy before development of neurological deficits.

BACKGROUND. To optimize selection of a radiotherapy schedule for patients with spinal metastases, the authors analyzed prognostic factors and developed a scoring system to predict survival in such patients. METHODS. Five‐hundred forty‐four patients with spinal metastases received radiotherapy at Shizuoka Cancer Center Hospital between September 2002 and November 2006. Prognostic factors for survival were studied using a Cox proportional hazards model, and a scoring system was developed based on regression coefficients: Three points were given for an unfavorable tumor type and bad performance status (≥3); 2 points were given for hypercalcemia, visceral metastases, and previous chemotherapy; and 1 point was given for multiple bone metastases and age ≥71 years. RESULTS. The overall survival rates after 6 months, 12 months, and 24 months were 49%, 32%, and 19%, respectively, and the median survival was 5.9 months (95% confidence interval, 4.9‐6.8 months). In total, 503 patients (93%) were followed for ≥12 months or until death. These patients were separated into Groups A, B, and C based on scores of 0 to 4, 5 to 9, and 10 to 14, respectively. These groups included 24%, 57%, and 19% of patients, respectively; and the mean median survival for Groups A, B, and C was 27.1 months, 5.4 months, and 1.8 months, respectively. Overall survival rates after 6 months, 12 months, and 24 months were 89%, 77%, and 54% in Group A; 46%, 22%, and 9% in Group B; and 7%, 4%, and 0% in Group C, respectively (P < .001). CONCLUSIONS. The scoring system was able to predict the survival of patients with spinal metastases and may be useful for selecting an optimal radiotherapy schedule. Cancer 2008. © 2008 American Cancer Society.
