Necrosis culminates in spilling cellular content through the permeabilized plasma membrane, thereby releasing potentially immunostimulatory molecules in the pericellular space of dead cells. Accordingly, molecules involved in necroptotic signaling, such as receptor-interacting serine/threonine-protein kinase 3 (RIPK3) and mixed lineage kinase-like (MLKL) have been found to stimulate anticancer immune responses in mouse models of chemotherapy. mRNAs encoding prominent pro-necrotic gene products (RIPK1, RIPK3, MLKL, PGAM5 and DFNA5) were correlated with immune-related metagenes in several cancer types (breast, colorectal, lung, ovary, melanoma), revealing the strongest associations in breast cancer...

Etoposide is widely used in the chemotherapy of a variety of malignancies. But the strong lipophilicity, poor bioavailability, and severe side effects of etoposide limit its clinical application. The aim of this study was to develop sustained-release etoposide-loaded implants and evaluate antitumor activity of the implants after intratumoral implantation. We prepared the implants containing etoposide, poly(L-lactid acid) and polyethylene glycol 4000 by the direct compression method. The implants were characterized regarding drug-excipient compatibility, content uniformity, morphology, sterility, in vitro, and in vivo release profiles...

Multifunctional nanocarrier-based theranostics is currently considered to solve some key unmet challenges in cancer treatment. Here we report a nanocarrier platform, named carbon dot (CD) created mesoporous hollow organosilica (C-hMOS) nanoparticles, to deliver anticancer drug and to enable optical imaging. The hollow structure was formed by the removal of a nanorod core template, and at the same time, the fluorescent signal was endowed from the heat-treated organosilica network. Thanks to the hollow and mesoporous structure, the C-hMOS effectively loaded doxorubicin (DOX) for cancer chemotherapy...

Isolated hilar and mediastinal recurrence (IMHR) following external beam radiation therapy (EBRT) in patients with lung cancer is common. These patients do not have many treatment options and are usually offered palliative chemotherapy or best supportive care. Endobronchial ultrasound (EBUS)-guided intratumoral injection of cisplatin (ITC) is a novel approach for these patients. The procedure is performed under conscious sedation. The lesion is located with a bronchoscopy using EBUS, and a 22-gauge EBUS needle is advanced through the working channel of the scope and locked in position...

Doxorubicin (DOX) is a well-known cytotoxic agent used extensively as a chemotherapeutic drug to eradicate a wide variety of human cancers. Reactive oxygen species (ROS)-mediated oxidative stress during DOX treatment can induce cardiac, renal, and hepatic toxicities, which can constrain its use as a potential cytotoxic agent. The present work investigates the antioxidant potential of naringenin (NAR) against DOXinduced toxicities of a Dalton's lymphoma ascites (DLA) tumor-bearing mouse model. Mice were randomized into four groups: a negative control, positive control, DOX (2...

Lin Shi, Xiangdong Wang
Patients with lung cancer still have high mortality, recurrence rate after adjuvant treatment, and poor five-year survival rates, despite of advances in multidisciplinary anti-cancer therapies, e.g. chemotherapy, radiotherapy and targeted therapies, It depends upon the presence of intratumoral heterogeneity and complexity of lung cancer. There is growing evidence to suggest that osteopontin (OPN) may play a critical role in tumor progression and metastasis. The present review briefly describes the structure and molecular biology of OPN, highlights the role of OPN in the development and metastasis of lung cancer, and summarizes potential mechanisms of OPN heterogeneity in tumor to underline some of these inconsistencies...

Non-small Cell Lung Cancer (NSCLC) remains a deadly disease despite aggressive treatment protocols which incorporate chemotherapy, radiation and surgery. These traditional approaches have reached a plateau in therapeutic benefit. There is emerging evidence suggesting that immunotherapy can serve as an alternative treatment modality for NSCLC. Our group has nearly two decades of experience involving immuno-gene therapy with Ad.hIFN-α and Ad.hIFN-β in human mesothelioma trials, and has observed both safety and efficacy in treatment of Thoracic malignancies...

BACKGROUND: Platinum (Pt)-based chemotherapy is the standard of care for muscle-invasive bladder cancer (MIBC). However, resistance is a major limitation. Reduced intratumoral drug accumulation is an important mechanism of platinum resistance. Our group previously demonstrated a significant correlation between tissue Pt concentration and tumor response to Pt-based neoadjuvant chemotherapy (NAC) in lung cancer. We hypothesized that increased Pt concentration in radical cystectomy (RC) specimens would correlate with improved pathologic response to Pt-based NAC in MIBC...

Cancer progression and metastasis relies much on vasculature networks in tumor microenvironment, and the combination treatment with chemotherapeutic drugs and vascular disrupting agents represents apparent clinical benefits. In the current study, fiber fragments with loadings of hydroxycamptothecin (HCPT) or combretastatin A-4 (CA4) were proposed for tumor inhibition and blood vessel disruption after local administration in tumors. To address challenges in balancing the disruption of tumor vessels and intratumoral uptake of chemotherapeutic agents, this study is focus on release tuning of HCPT and CA4 from the fiber fragment mixtures...

BACKGROUND: Hypoxia is associated with resistance to chemotherapy and radiotherapy and is randomly distributed within malignancies. Characterization of changes in intratumoral hypoxic regions is possible with specially developed PET tracers such as (18)F-fluoroazomycin arabinoside ((18)F-FAZA) while tumor metabolism can be measured with 2-deoxy-2-[(18)F]fluoro-D-glucose ((18)F-FDG). The purpose of this study was to study the effects of chemotherapy on (18)F-FAZA and (18)F-FDG uptake simultaneously in non-small-cell lung cancer (NSCLC) patients METHODS: At baseline and after the second chemotherapy cycle, both PET/CT with (18)F-FDG and (18)F-FAZA was performed in seven patients with metastasized NSCLC...

BACKGROUND: Renal cell carcinoma (RCC) is a highly vascularized cancer resistant to chemotherapy and radiotherapy. RCC is frequently infiltrated with immune cells, with macrophages being the most abundant cell type. Alternatively activated M2 macrophages are known to contribute to tumor progression. Endostatin (ES) is a fragment of collagen XVIII that possesses antiangiogenic activity. In this study, we investigated the impact of ES gene therapy on the polarization of tumor-associated macrophages (TAMs) in lung metastases from tumor-bearing mice...

Locoregional delivery of anticancer drugs is an attractive approach to minimize adverse effects associated with intravenous chemotherapy. Polymer-based drug depots injected or implanted intratumorally or adjacent to the tumor can provide long-term local drug exposure. This review highlights studies in which drug-eluting depots have been applied locally in the treatment of cancer. In many cases such drug depots are used for prevention of tumor recurrence after surgery to eradicate remaining tumor cells. Clinical success has been reported for the treatment of brain cancer and liver cancer, and preclinical studies showed proof-of-concept for inhaled drug depots in lung cancer and intraperitoneally injected depots for the treatment of abdominal cancer...

As tumors grow, they acquire mutations, some of which create neoantigens that influence the response of patients to immune checkpoint inhibitors. We explored the impact of neoantigen intratumor heterogeneity (ITH) on antitumor immunity. Through integrated analysis of ITH and neoantigen burden, we demonstrate a relationship between clonal neoantigen burden and overall survival in primary lung adenocarcinomas. CD8(+)tumor-infiltrating lymphocytes reactive to clonal neoantigens were identified in early-stage non-small cell lung cancer and expressed high levels of PD-1...

The tumor microenvironment (TME) represents a milieu that enables tumor cells to acquire the hallmarks of cancer. The TME is heterogeneous in composition and consists of cellular components, growth factors, proteases, and extracellular matrix. Concerted interactions between genetically altered tumor cells and genetically stable intratumoral stromal cells result in an "activated/reprogramed" stroma that promotes carcinogenesis by contributing to inflammation, immune suppression, therapeutic resistance, and generating premetastatic niches that support the initiation and establishment of distant metastasis...

Photodynamic therapy (PDT) is an established treatment modality for non-small cell lung cancer. Phototoxicity, the primary adverse event, is expected to be minimized with the introduction of new photosensitizers that have shown promising results in phase I and II clinical studies. Early-stage and superficial endobronchial lesions less than 1 cm in thickness can be effectively treated with external light sources. Thicker lesions and peripheral lesions may be amenable to interstitial PDT, where the light is delivered intratumorally...
