Gastric metastasis from primary lung adenocarcinoma mimicking primary gastric cancer

World Journal of Gastrointestinal Oncology 2015年第3期7卷 12-16页

Gastric metastases from lung adenocarcinoma are rare. Because gastric metastasis grossly resembles advanced gastric cancer, it is difficult to diagnose gastric metastasis especially when the histology of the primary lung cancer is adenocarcinoma. We describe a case of gastric metastasis from primary lung adenocarcinoma mimicking Borrmann type Ⅳ primary gastric cancer. A 68-year-old man with known lung adenocarcinoma with multiple bone metastases had been experiencing progressive epigastric pain and dyspepsia over one year. Esophagogastroduodenoscopy revealed linitis plasticalike lesions in the fundus of the stomach. Pathologic examination revealed a moderately differentiated adenocarcinoma with submucosal infiltration. Positive immunohistochemical staining for thyroid transcription factor-1(TTF-1) and napsin A(Nap-A) confirmed that the metastasis was pulmonary in origin. The patient had been treated with palliative chemotherapy for the lung cancer and had lived for over fifteen months after the diagnosis of gastric metastasis. Clinicians should be aware of the possibility of gastric metastasis in patients with primary lung adenocarcinoma, and additional immunohistochemical staining for Nap-A as well as TTF-1 may help in differentiating its origin.

All-in-one glycol chitosan nanoparticles for co-delivery of doxorubicin and anti-PD-L1 peptide in cancer immunotherapy

Synergistic immunotherapy of immune checkpoint blockade (ICB) and immunogenic cell death (ICD) has shown remarkable therapeutic efficacy in various cancers. However, patients show low response rates and undesirable outcomes to these combination therapies owing to the recycling mechanism of programmed death-ligand 1 (PD-L1) and the systemic toxicity of ICD-inducing chemotherapeutic drugs. Herein, we propose all-in-one glycol chitosan nanoparticles (CNPs) that can deliver anti-PD-L1 peptide (PP) and doxorubicin (DOX) to targeted tumor tissues for a safe and more effective synergistic immunotherapy. The PP-CNPs, which are prepared by conjugating ᴅ-form PP (NYSKPTDRQYHF) to CNPs, form stable nanoparticles that promote multivalent binding with PD-L1 proteins on the targeted tumor cell surface, resulting in effective lysosomal PD-L1 degradation in contrast with anti-PD-L1 antibody, which induces recycling of endocytosed PD-L1. Consequently, PP-CNPs prevent subcellular PD-L1 recycling and eventually destruct immune escape mechanism in CT26 colon tumor-bearing mice. Moreover, the ICD inducer, DOX is loaded into PP-CNPs (DOX-PP-CNPs) for synergistic ICD and ICB therapy, inducing a large number of damage-associated molecular patterns (DAMPs) in targeted tumor tissues with minimal toxicity in normal tissues. When the DOX-PP-CNPs are intravenously injected into CT26 colon tumor-bearing mice, PP and DOX are efficiently delivered to the tumor tissues via nanoparticle-derived passive and active targeting, which eventually induce both lysosomal PD-L1 degradation and substantial ICD, resulting in a high rate of complete tumor regression (CR: 60%) by a strong antitumor immune response. Collectively, this study demonstrates the superior efficacy of synergistic immunotherapy using all-in-one nanoparticles to deliver PP and DOX to targeted tumor tissues.

AIM: To identify the factors that differentiate acute hepatitis B(AHB) from chronic hepatitis B with acute exacerbation(CHB-AE).METHODS: From 2004 to 2013, a total of 82 patients(male n = 52, 63.4%; female n = 30, 36.6%) with clinical features of acute hepatitis with immunoglobulin M antibodies to the hepatitis B core antigen(Ig M antiHBc) were retrospectively enrolled and divided into two groups; AHB(n = 53) and CHB-AE(n = 29). The AHB group was defined as patients without a history of hepatitis B virus(HBV) infection before the episode and with loss of hepatitis B surface antigen within 6 mo after onset of acute hepatitis. Biochemical and virological profiles and the sample/cutoff(S/CO) ratio of Ig M anti-HBc were compared to determine the differential diagnostic ***: The multivariate analysis demonstrated that, the S/CO ratio of Ig M anti-HBc and HBV DNA levels were meaningful factors. The S/CO ratio of Ig M anti-HBc was significantly higher in the AHB group, while the HBV DNA level was significantly higher in the CHB-AE group. The optimal cutoff values of Ig M anti-HBc and HBV DNA levels for differentiating the two conditions were 8 S/CO ratio and 5.5 log10 IU/m L, respectively. The sensitivity and specificity were 96.2% and 89.7% for the S/CO ratio of Ig M anti-HBc and 81.1% and 72.4% for HBV DNA levels, respectively. The area under receiver operating characteristic curves of both the S/CO ratio of Ig M anti-HBc and HBV DNA levels were not significantly different(0.933 vs 0.844, P = 0.105). When combining Ig M anti-HBc and HBV DNA, the diagnostic power significantly improved compared to HBV DNA alone(P = 0.0056). The combination of these factors yielded a sensitivity and specificity of 98.1% and 86.2%, ***: The combination of the S/CO ratio of Ig M anti-HBc and HBV DNA levels was a useful tool for differentiating AHB from CHB-AE in patients with positive Ig M anti-HBc.

AIM: To predict the rate of lymph node(LN) metastasis in diffuse- and mixed-type early gastric cancers(EGC) for guidelines of the ***: We reviewed 550 cases of EGC withdiffuse- and mixed-type histology. We investigated the clinicopathological factors and histopathological components that influence the probability of LN metastasis, including sex, age, site, gross type, presence of ulceration, tumour size, depth of invasion, perineural invasion, lymphovascular invasion, and LN metastasis status. We reviewed all slides and estimated the proportions of each tumour component; pure diffuse type, mixed-predominantly diffuse type(diffuse > intestinal type), mixed-predominantly intestinal type(intestinal > diffuse type), and mixed diffuse = intestinal type. We calculated the extents of the respective ***: LN metastasis was observed in 12.9%(71/550) of early gastric cancers cases [15/288 mucosal EGCs(5.2%) and 56/262 submucosal EGCs(21.4%)]. Of 550 cases, 302 were diffuse-type and 248 were mixed-type EGCs. Of 248 mixed-type EGCs, 163 were mixed-predominantly diffuse type, 82 were mixed-predominantly intestinal type, and 3 were mixed diffuse = intestinal type. Mixed-type cases with predominantly diffuse type histology showed a higher frequency of LN metastasis(20.2%) than cases of pure diffuse type(9.3%) and predominantly intestinal type(12.2%) histology. We measured the dimensions of each component(intestinal and diffuse type) to determine the association of the extent of each component with LN metastasis in mixed-type gastric carcinoma. The total tumour size and the extent of poorly differentiated components was associated with LN metastasis, while that of signet ring cell components was ***: We recommend careful identification and quantitative evaluation of mixed-type early gastric cancer components after endoscopic resection to determine the intensity of the treatment.
