New type of cancer therapy described

A new study has found that a new chemotherapy is effective against both pediatric and adult cancers, and that it allows other chemotherapies to more readily reach their targets.

SummaryNon-small cell lung cancer (NSCLC) treatment was booming at this year ’s ASCO 2018 meeting as several well-performed phase III trials with practice-changing potential were presented. Thereby immune checkpoint blockade (ICB) consolidated its major role in the treatment of NSCLC patients without genetic alterations and extended its use by showing impressive data on I CB combination therapies (mainly combined with chemotherapy). Furthermore the role of predictive biomarkers for ICB therapy (Programmed death-ligand 1 [PD-L1] expression, tumor mutational burden [TMB] testing and others) have been further ...

AbstractPurpose of reviewThere is growing evidence to suggest that gut microbiota plays an important role in colorectal carcinogenesis. Western diet is associated with gut microbial dysbiosis, which leads to inflammation, oxidative stress, and genotoxic effects, all common risk factors for colorectal cancer.Recent findingsFusobacterium nucleatum,Helicobacter pylori,Bacteroides fragilis,Escherichia coli,and Streptococcus bovis are the main bacterial species associated with colorectal carcinogenesis. Gut microbiota transforms both diet- (meat, processed meat products, fat) and host (bile acids)-derived precursors into carcin...

In this study, we successfully incorporated a hydrophobic drug, bortezomib (Bor), into folic acid (FA)-conjugated Cs/Chs self-assembled NPs (Bor/Cs/Chs-FA) for colorectal cancer therapy. The particle size and polydispersity index of Bor/Cs/Chs-FA were ∼196.5 ± 1.2 nm and ∼0.21 ± 0.5, respectively. A pH-dependent release profile was observed, facilitating cancer cell-targeted drug release under an acidic tumor microenvironment. Moreover, in vitro data revealed enhanced cellular uptake and apoptosis in folate receptor-expressing colorectal cancer cells (HCT-116 and HT-29) as compared to that in lung can...

Publication date: 1 January 2019Source: Colloids and Surfaces B: Biointerfaces, Volume 173Author(s): Ying Yang, Xue Yang, Huipeng Li, Chenzi Li, Huaqian Ding, Mengting Zhang, Yuxin Guo, Minjie SunAbstractPhotodynamic therapy (PDT) as a promising noninvasive and effective treatment modality has been clinically approved for cancer therapy. However, the poor selectivity of tumor and hypoxia-induced resistance constrain PDT efficacy immensely. To further enhance PDT’s potency, we developed a drug delivery system based on liposome combining PDT and chemotherapeutics. The lipophilic IR780 was loaded into the lipid bilayer ...

This study explores the breast tumor regression in vivo by synergistic photothermal-chemotherapy based on liposomal nanocomplex (folic acid-gold nanorods-anticancer drug-liposome). The proposed liposomal nanocomplex can enhance the tumor targeting by functionalizing folic acid (FA) molecules on the surface of liposome that encapsulates both gold nanorods (AuNRs) and the doxorubicin (DOX) to combine the photothermal therapy and the chemotherapy, respectively. Herein, 7-nm gold nanorods were fabricated and co-encapsulated with DOX into nanoliposomes functionalized with FA, with an average diameter of 154 nm, for activ...

Abstract Over the past decades, effective cancer therapies have resulted in a significant improvement in the survival rates for a number of cancers and an increase in the number of cancer survivors. Radiation therapy is widely used in the treatment of cancer, and it can induce various cardiotoxicities that differ considerably from chemotherapy-induced cardiotoxicity. They occur primarily as late radiation-induced complications, several years from the end of anticancer treatment and present as coronary artery disease, heart failure, pericardial disease, valvular heart disease and arrhythmias. Patients who recovered...

AbstractPurposeThis observational study was designed to measure baseline energy parameters and body composition in early-stage breast cancer patients, and to follow changes during and after various modalities of treatment. This will provide information to aid in the development of individualized physical activity intervention strategies.MethodsPatients with newly diagnosed stage 0 –III breast cancer were enrolled into three cohorts: A (local therapy alone), B (endocrine therapy), or C (chemotherapy with or without endocrine therapy). At baseline, 6 months, and 12 months, subjects underwent a stationary bicy...

CONCLUSIONS: Compared to ADT alone, the early (within 120 days of beginning ADT) addition of taxane-based chemotherapy to ADT for hormone-sensitive prostate cancer probably prolongs both overall and disease-specific survival and delays disease progression. There may be an increase in toxicity with taxane-based chemotherapy in combination with ADT. There may also be a small, clinically unimportant improvement in quality of life at 12 months with taxane-based chemotherapy and ADT treatment. PMID: 30320443 [PubMed - as supplied by publisher]
