OBJECTIVETo throw light on the superiority of the anti-angiogenesis activity of endostatin (ES) derivatives by reviewing the recent progress in the field of ES molecular structure modification.

DATA SOURCESThe data used in this article were mainly from PubMed with relevant English articles published from 1971 to May 2008. The search terms were "endostatin" and "angiothesis".

STUDY SELECTIONArticles involved in the ES molecular structure modification and the original milestone articles were selected.

RESULTSA number of ES derivatives were designed and studied to improve its clinical relevance. The modified ES with polyethylene glycol (PEG), low molecular weight heparin (LMWH) and IgG Fc domain extended the circulation half-life. Meanwhile the recombinant ESs showed more potent anti-tumor activity than native ES in mouse xenografts. Mutated ES also changed its anti-angiogenesis activity.

CONCLUSIONSThe anti-angiogenesis treatment remains a promising tumor therapeutic strategy. New ES derivatives would be a good choice to meet the future challenge on clinical application of ES.

Antiangiogenic therapy has entered clinical practice and shown good clinical benefits. However, no validated biomarker has been confirmed to be useful for screening patients who will respond to antiangiogenic therapy. Many systemic, circulating, tissue and imaging biomarkers are emerging and need to be prospectively validated.

Lung cancer is a highly vascular tumors, over the past ten years, anti-angiogenes is has been proved to be an effective and highly promising combinational treatment. The data of the combination of anti-angiogenesis with chemotherapy, targeted therapy, immunotherapy has been constantly updating. Advanced lung cancer patients, no matter different groups or different stages of the disease, are benefited from anti-angiogenes. In this paper, based on the clinical status and unsolved problems, combined with the latest clinical and translational research data, we reviewed the current anti-angiogenesis treatment of lung cancer.

BACKGROUNDWhat benefits and toxicities patients acquire from the use of bevacizumab combined with firstline chemotherapy remains controversial. This study was performed to evaluate the efficacy and safety of first-line chemotherapy plus bevacizumab in patients with metastatic colorectal cancer (mCRC).

METHODSSeveral databases, including PubMed, Embase, and Cochrane Library, were searched up to April 30, 2013. Eligible studies were only randomized, controlled trials (RCTs) with a direct comparison between mCRC patients treated with and without bevacizumab. Overall risk ratio (RR), hazard ratio (HR), odds ratio (OR), and 95% confidence intervals (CI) were calculated employing fixed or random-effects models depending on the heterogeneity of the included trials.

RESULTSSix RCTs, including 1582 patients in chemotherapy plus bevacizumab group and 1484 patients in chemotherapyalone group, were included. Overall, the addition of bevacizumab to first-line chemotherapy increased overall response rate (ORR) by 4.5%, prolonged both progression-free survival (PFS) and overall survival (OS), and increased the rate of total Grades 3 or 4 adverse events (G3/4AEs) by 6.9%. Significant differences were found in ORR (RR = 1.22 (95% CI 1.01-1.46), P = 0.03), PFS (HR = 0.60 (95% CI 0.47-0.77), P < 0.0001), OS (HR = 0.83 (95% CI 0.70-0.97), P = 0.02), and any G3/4AEs (OR = 1.56 (95% CI 1.29-1.89), P < 0.00001).

CONCLUSIONBevacizumab is a valuable addition to the current first-line chemotherapy regimens used in patients with mCRC, because of conferring a significant improvement in ORR, PFS, and OS, even though it increased adverse events.

Arsenic trioxide has been used to treat lymphoma experimentally since it was used to treat acute promyelocytic leukemia successfully. Massive works in this field have been done throughout the world. It was found that arsenic trioxide exerted an anti-lymphomatic effect via many pathways, and many substances could increase or reduce this effect. Arsenic trioxide can be used to treat relapsed and refractory lymphomas resistant to other chemotherapies with some therapeutic effects and limited side effects, which indicates that arsenic trioxide is a new potential drug for lymphoma. This article is an overview about these foundational and clinical studies.

Molecule-targeting agents inhibit the proliferation of tumor cells by the molecular biological differences between tumor cells and normal cells, and finally kill tumor cells. This article introduces several molecule-targeting agents that are currently under clinical trials now.

Antiangiogenic therapy can generate a "normalization window" for tumor vasculature. This normalization process prunes immature vessels and improves the integrity and function of the remaining vasculature by enhancing the perivascular cell and basement membrane coverage in tumor, therefor creates a window of opportunity for improved sensitivity to ionizing radiation and the delivery of chemotherapeutic drugs. It provides a rational basis for the combination therapy of traditional Chinese drugs with radiation and perhaps other forms of chemotherapy. Antiangiogenic therapy with the traditional Chinese drug interfering in the the mechanisms of the normalization window in humans maybe harness a new approach to improve the sensitivity of tumors to radio- and chemotherapy.

OBJECTIVETo observe the therapeutic effect of propranolol with 1 064 nm Nd:YAG laser on proliferating hemangioma in body surface.

METHODS97 patients with proliferating hemangiomas in body surface were randomly assigned to three groups: A group (32 patients were treated by propranolol with 1064 nm Nd:YAG laser), B group (35 patients were treated by 1064 nm Nd:YAG laser), C group (30 patients were treated by propranolol). Their visual analog scores, clinical outcomes and adverse events were compared respectively.

RESULTS18 weeks later, A group had a mean visual analog score of 65.50 +/- 16.55, compared with 54.03 +/- 20.13 in B group, 28.08 +/- 30.34 in C group (P < 0.05); 24 weeks later, the mean visual analog scores of three groups were 76.88 +/- 19.05, 63.89 +/- 19.43 and 45.48 +/- 31.86 (P < 0.05). After 24 weeks' treatment, 9 cases (28.1%) in A group, 3 cases (8.6%) in B group, 1 cases (4.0%) in C group obtained complete healing (P < 0.05). To effect of adverse events in body surface, the mean score of B group was higher than the scores of A group and C group (P < 0.05).

CONCLUSIONSPropranolol with 1064 nm Nd:YAG laser is effective and safe in the treatment of proliferating hemangioma.

Thrombin is the most important factor in hemostasis. In recent years, it has been found that thrombin is a potent mitogen capable of inducing cellular functions. Therefore, it is proved to be of importance in promoting the growth, metastasis and angiogenesis of cancer. Anticoagulant therapy not only reduce the characteristic hypercoagulability of cancer, but also inhibits growth and metastasis of cancer, and alters the fundamental biology of cancer. In this paper thrombin and its receptor, relationship of thrombin and its receptor with cancer growth, metastasis and angiogenesis, the mechanisms of thrombin influence on cancer angiogenesis, as well as application prospects on anti-angiogenesis and anti-coagulation therapy were reviewed.
