We performed post-marketing surveillance to evaluate the safety and efficacy of cell-free and concentrated ascites reinfusion therapy (CART). In total, 356 CART sessions in 147 patients at 22 centers were performed. The most common primary disease was cancer (128 cases, 300 sessions). Mean amount of ascites collected was 3.7 L, and mean concentration ratio was 9.2. Mean amount of reinfused protein was 67.8 g (recovery rate, 72.0%). Performance status, dietary intake, urine volume, body weight and abdominal circumference were significantly improved after CART. Body temperature increased significantly, by 0.3°C on average. Concomitant steroids and/or NSAIDs use before reinfusion was significantly and negatively associated with increases in body temperature. Most adverse events were fever and chills. This study examined a large number of patients compared with previous studies, and showed that CART is an effective and relatively safe treatment for refractory ascites, such as malignant ascites.
We made use of hematoxylin and eosin (H&E) stain, Verhoeff van-Gieson stain for elastic tissue (EVG), and factor VIII-related antigen (FVIII-RA) to stain tissues excised from 94 patients with colorectal carcinoma. Of these 94, 49 died of disease within two years (Group I), and 45 survived for five years or longer (Group II) after surgery. In the tissues from both groups, the use of EVG stain revealed a higher incidence of vascular invasion than was seen with H&E stain. In Group I, the rates were 28.6 percent and 61.2 percent with H&E and EVG, respectively, and those in Group II were 4.4 percent and 31.1 percent, respectively. Conversely, the FVIII-RA stain showed a decrease in the incidence of vascular invasion in both groups. In Group I, when vascular invasion was examined in EVG-stained tissues, the incidence was 81.3 percent in cases of hematogenous metastases and 23.5 percent in those without hematogenous metastases (P less than 0.01). These differences were not evident with H&E. When observing the site of vascular invasion in tissues of the colorectal wall stained with EVG, intramural and extramural types of vascular invasion were seen in 20 percent and 80 percent of cases in Group I and in 93 percent and 7 percent of those in Group II, respectively. Thus, not only the frequency, but also the site, of vascular invasion into the colorectal wall evidenced with EVG stain provides a more precise prediction of the recurrence of hematogenous metastases.
Imaging techniques targeting tumor angiogenesis have been investigated for past decade. Of these, the radiolabeled Arg-Gly- Asp (RGD) peptide has been focused because it has high affinity and selectivity for integrin alpha(v)beta3. Integrin alpha(v)beta3 is expressed on the plasma membrane in an active status in which it binds its ligands and transduce signals when exposed activating external stimuli of tumor angiogenesis such as vascular endothelial growth factor (VEGF). Many linear or cyclic RGD peptides were developed for positron emission tomography (PET). In this review, we focused on currently developed RGD peptides as PET probes for non-invasive detection of integrin alpha(v)beta3 expression.
Aim: This study was performed to confirm the superior overall survival (OS) after pulmonary oligo-recurrence compared to pulmonary sync-oligometastases in a large nationwide study. Patients and Methods: Patients that met the following criteria were included: 1 to 5 lung-only metastases at the beginning of stereotactic body radiation therapy (SBRT) was performed between January 2004 and June 2015, and the biological effective dose (BED) of SBRT was 75 Gy or more. The parameters included in the analyses were age, gender, ECOG PS, primary lesion, pathology, oligoetastatic state, SBRT date, chemotherapy before SBRT, chemotherapy concurrent SBRT, chemotherapy after SBRT, maximum tumor diameter, number of metastases, field coplanarity, dose prescription, BED 10 , OTT of SBRT. Results: In total, 1,378 patients with 1,547 tumors were enrolled. Oligo-recurrence occurred in 1,016 patients, sync-oligometastases in 118, and unclassified oligometastases in 121. The three-year OS was 64.0% for oligorecurrence and 47.5% for sync-oligometastasis (p<0.001). In the multivariate analysis, the hazard ratio (HR) for syncoligometastases versus oligo-recurrence was 1.601 (p=0.014). Adverse events of Grade 5 were occurred in 3 patients. Conclusion: This is the first nationwide to indicate that the OS 393
BackgroundTo investigate the prognostic value of oligo-recurrence in patients with brain-only oligometastases of non-small cell lung cancer (NSCLC) treated with stereotactic radiosurgery (SRS) or stereotactic radiotherapy (SRT).MethodsPatients treated with SRS or SRT for brain-only NSCLC oligometastases in 6 high-volume institutions in Japan between 1996 and 2008 were reviewed. Eligible patients met 1), 2), and 4) or 1), 3), and 4) of the following: 1) NSCLC with 1 to 4 brain metastases on magnetic resonance imaging (MRI) treated with SRS or SRT; 2) control of the primary lesions (thorax) at the time of SRS or SRT for brain metastases (patients meeting this criterion formed the oligo-recurrence group); 3) with SRS or SRT for brain metastases, concomitant treatment for active primary lesions (thorax) with curative surgery or curative stereotactic body radiotherapy (SBRT), or curative chemoradiotherapy (sync-oligometastases group); and 4) Karnofsky performance status (KPS) ≥70.ResultsThe median overall survival (OS) of all 61 patients was 26 months (95 % CI: 17.5–34.5 months). The 2-year and 5-year overall survival rates were 60.7 and 15.7 %, respectively. Stratified by oligostatus, the sync-oligometastases group achieved a median OS of 18 months (95 % CI: 14.8–21.1 months) and a 5-year OS of 0 %, while the oligo-recurrence group achieved a median OS of 41 months (95 % CI: 27.8–54.2 months) and a 5-year OS of 18.6 %. On multivariate analysis, oligo-recurrence was the only significant independent factor related to a favorable prognosis (hazard ratio: 0.253 (95 % CI: 0.082–0.043) (p = 0.025).ConclusionsThe presence of oligo-recurrence can predict a favorable prognosis of brain-only oligometastases in patients with NSCLC treated with SRS or SRT.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
