Evaluation of HCPTd1, d14-double passaged intervening chemotherapy protocol for hepatocellular carcinoma

[Clinical Observation of Gefitinib with Pericardial Perfusion for Advanced Non-small Cell Lung Cancer]

BACKGROUND

Epidermal growth factor receptor (EGFR) mutation non-small cell lung cancer (NSCLC) is an important subtype of lung cancer. The incidence of malignant pericardial effusion (MPCE) in EGFR-mutant NSCLC patients is high. However, there are few researches on the treatmentof this type of patients.

METHODS

We collected data on clinical characteristics and treatment of advanced NSCLC patients who harboring EGFR mutants and MPCE between January 2010 and December 2016. The treatments were divided into three groups: oral gefitinib combined with pericardial perfusion of hydroxycamptotheci (HCPT) group (gefitinib/HCPT); intravenous chemotherapy combined with pericardial perfusion of HCPT group (chemotherapy/HCPT) and gefitinib monotherapy group. And we retrospectively analyzed patients' outcomes in three groups.

RESULTS

In 273 advanced NSCLC patients with EGFR mutations, 29 cases had pericardial effusion, among which 6 patients with small amount of pericardial effusion were excluded, and 23 patients were analyzed. Median pericardium progression free survival (PFS) was 247 days. PFS for gefitinib/HCPT group (460 days) was superior to PFS for chemotherapy/HCPT group (94 days, P=0.008) and gefitinib monotherapy group (131 days, P=0.032). As for the efficacy of primary pulmonary lesions, the efficacy in gefitinib/ HCPT group was superior to chemotherapy/HCPT group [objective response rate (ORR): 33.3% vs 12.5%; disease control rate (DCR): 86.7% vs 62.5%]. There is no difference of ORR and DCR between gefitinib/HCPT group and gefitinib monotherapy group. No obvious adverse reaction was observed in all three groups.

CONCLUSIONS

First-line gefitinib therapy combined with pericardial perfusion of HCPT can improve pericardium PFS for advanced NSCLC patients who harboring EGFR mutants andmalignantpericardial effusion. This finding should be confirmed further through multicenter, prospective clinical trials with large sample size.

Circulating specific biomarkers in diagnosis of hepatocellular carcinoma and its metastasis monitoring

Hepatocellular carcinoma (HCC) is one of the most common and rapidly fatal malignancies worldwide with a multifactorial, multistep, complex process and poor prognosis. Its early diagnosis and metastasis monitoring are of the utmost importance. Hepatoma tissues synthesize various tumor-related proteins, genes, enzymes, microRNA, etc. and then secrete into the blood. Detections of circulating biomarkers are useful to find tumor at an early stage or monitor metastasis after postoperative treatment. This paper summarizes recent studies of specific biomarkers at early diagnosis or in monitoring metastasis or postoperative recurrence of HCC.
