Ruptured hepatoblastoma with massive internal bleeding in an adult

Hepatoblastoma is the most common primary hepatic tumor of children. However, only a very few cases have been reported in adults. Most studies support treatment with chemotherapy followed by surgical resection. We present the first reported case of adult hepatoblastoma in Taiwan. A 52-year-old female suffered from sudden onset of abdominal pain and general weakness for days.Internal bleeding with hemorrhagic shock was suspected and two massive lesions in both lobes of the liver with hemoperitoneum were noted from imaging studies.Surgical resection of the larger left lobe tumor and radio-frequency ablation of the right smaller one were performed. The histopathology diagnosis was of a hepatoblastoma.

Relationship between epidermal growth factor receptor gene mutation and copy number in Chinese patients with non-small cell lung cancer

Epidermal growth factor receptor(EGFR) gene mutation and copy number are useful predictive markers that guide the selection of non-small cell lung cancer(NSCLC) patients for EGFR-targeting therapy.This study aimed to investigate the correlation between EGFR gene mutation and copy number and clinicopathologic characteristics of Chinese patients with NSCLC.NSCLC specimens collected from 205 patients between November 2009 and January 2011 were selected to detect EGFR gene mutations with real-time polymerase chain reaction(RT-PCR) and to detect EGFR gene copy number with fluorescence in situ hybridization(FISH).EGFR mutations primarily occurred in females,non-smokers,and patients with adenocarinomas(all P < 0.001).Tissues from 128(62%) patients were FISH-positive for EGFR,including 37(18%) with gene amplification and 91(44%) with high polysomy.EGFR gene mutation was correlated with FISH-positive status(R = 0.340,P < 0.001).Multivariate analysis showed that not smoking(OR = 5.910,95% CI = 2.363-14.779,P < 0.001) and having adenocarcinoma(OR = 0.122,95% CI = 0.026-0.581,P = 0.008) were favorable factors for EGFR gene mutation.These results show a high frequency of EGFR FISH positivity in NSCLC tissues from Chinese patients and a significant relevance between EGFR gene mutations and FISH-positive status.Among the FISH-positive samples,EGFR gene mutation occurred more frequently in samples with gene amplification compared to those with high polysomy,suggesting that EGFR mutation and gene amplification should be used as clinical decision parameters to predict response to EGFR-targeting therapy.

中国人非小细胞肺癌表皮生长因子受体EGFR基因突变与血浆纤维蛋白原水平之间的相关性(英文)

Objective:The plasma fibrinogen levels had not only been used as an independent prognostic parameter for the patients with non-small cell lung cancer (NSCLC), but also as a promising biomarker for evaluating the efficacy of chemotherapy. This study aimed to investigate the correlation between the plasma fibrinogen levels and epidermal growth factor receptor (EGFR) gene mutation and clinical-pathological characteristics of Chinese patients with NSCLC. Methods:In this retrospective study, NSCLC specimens collected from 352 patients between November 2009 and November 2011 were selected to detect EGFR gene mutation with real-time polymerase chain reaction (RT-PCR). In these specimens, 308 ones were also detected EGFR gene copy number with fluorescence in situ hybridization (FISH). Coagulation makers were examined prior to the operations. The association between the plasma fibrinogen levels and EGFR gene mutation and clinical-pathological characteristics were analyzed using SPSS 16.0 software. Results:The median pre-operation plasma fibrinogen level was 3.55 g/L (109/352) patients with higher plasma fibrinogen level (> 4.0 g/L). The lower plasma fibrinogen levels correlated significantly with EGFR gene mutations (P < 0.001), the similar result was seen in platelet counts (P = 0.026). A linear correlation was found between the plasma fibrinogen levels and the platelet counts in NSCLC patients (R 2 = 0.209, P < 0.001). Pre-operation plasma fibrinogen levels correlated with gender (P < 0.001), smoking status (P < 0.001), and histology (P < 0.001). There were significant link between the above clinical-pathological characteristics and EGFR gene mutations. In addition, EGFR gene mutation was correlated with FISH-positive status (P < 0.001). Moreover, both plasma fibrinogen level (P = 0.024) and the EGFR gene copy number (P = 0.040) had significant relationships with the pathological TNM stage. Conclusion:This study showed that a significant relevance between plasma fibrinogen levels and EGFR gene mutations. The plasma fibrinogen level might be as a clinical decision parameter for evaluating the efficacy of anti-EGFR tyrosine kinase inhibitors (TKIs) in NSCLC. The patients of NSCLC had higher indicate have poor benefits from anti-EFGR TKIs. In addition, pre-operation plasma fibrinogen level could be used as an indepedent prognostic biomarker for the patients with NSCLC.

Effect of Tegafur Gimeracil Oteracil Potassium Capsule + Kangai injection + intensity-modulated radiation therapy on the cellular malignant biological processes in advanced cervical cancer lesion

Objective:To study the effect of Tegafur Gimeracil Oteracil Potassium Capsule + Kangai injection + intensity-modulated radiation therapy on the cellular malignant biological processes in advanced cervical cancer lesion.Methods: Patients who were diagnosed with advanced cervical cancer in the Second People Hospital of Banan District Chongqing between April 2015 and March 2017 were selected and divided into two groups, group A received Tegafur Gimeracil Oteracil Potassium Capsule + Kangai injection + intensity-modulated radiation therapy, and group B received cisplatin + intensity-modulated radiation therapy. Serum contents of tumor markers, tumor invasion molecules and tumor proliferation molecules of two groups of patients were detected before treatment as well as 2 weeks and 4 weeks after treatment.Results: Serum E-cad, STMN1, Fas and p53 levels of both groups of patients 2 weeks and 4 weeks after treatment were significantly higher than those before treatment while TSGF, TK1, SCC-Ag, CA125, OPN, MMP9, NGAL, CyclinE, CyclinD1 and PCNA levels were significantly lower than those before treatment, and serum E-cad, STMN1, Fas and p53 levels of group A 2 weeks and 4 weeks after treatment were significantly higher than those of group B while TSGF, TK1, SCC-Ag, CA125, OPN, MMP9, NGAL, CyclinE, CyclinD1 and PCNA levels were significantly lower than those of group B.Conclusion: Tegafur Gimeracil Oteracil Potassium Capsule + Kangai injection + intensity-modulated radiation therapy for advanced cervical cancer can induce cancer cell apoptosis and inhibit cancer cell proliferation and invasion.
