Authors: Kreidieh M, Zeidan YH, Shamseddine A Abstract Treatment recommendations for primary liver malignancies, including hepatocellular carcinoma (HCC) and cholangiocarcinoma (CCA), are complex and require a multidisciplinary approach. Despite surgical options that are potentially curative, options for nonsurgical candidates include systemic therapy, radiotherapy (RT), transarterial chemoembolization (TACE), and radiofrequency ablation (RFA). Stereotactic Body Radiation Therapy (SBRT) is now in routine use for the treatment of lung cancer, and there is growing evidence supporting its use in liver tumors. SBRT has...

Authors: Niranjan A, Lunsford LD, Ahluwalia MS Abstract The most common primary cancers that metastasize to the brain are lung cancer, breast cancer, and melanoma. The established management approaches for brain metastasis include stereotactic radiosurgery, fractionated radiation therapy, and surgical resection. In the past the role of medical therapies in brain metastases was limited. In the last decade, our understanding of molecular drivers of brain metastases and CNS penetration of drugs across the blood-brain barrier has improved. The molecular targeted tyrosine kinase inhibitors have shown effectiveness in br...

Immune checkpoint inhibition (ICI) targeting the programmed death receptor 1 (PD-1) has shown promising results in the fight against cancer. Systemic anti-tumor reactions due to radiation therapy (RT) can lead to regression of non-irradiated lesions (NiLs), termed "abscopal effect" (AbE). Combination of both treatments can enhance this effect. The aim of this study was to evaluate AbEs during anti-PD-1 therapy and irradiation. We screened 168 patients receiving pembrolizumab or nivolumab at our center. Inclusion criteria were start of RT within 1 month after the first or last application of pembrolizumab (2mg/kg...

Viacheslav Soyfer1* and Benjamin W. Corn2 1Tel Aviv Medical Center, Tel Aviv University, Tel Aviv, Israel 2Shaare Zedek Medical Center, Hebrew University of Jerusalem, Jerusalem, Israel Outcomes for patients with locally-advanced Non Small Cell Lung Cancer (NSCLC) remain poor. In the context of definitive (as opposed to neoadjuvant) treatment, radiation oncologists have traditionally embraced dose escalation as a means to improve control of the primary tumor as well as draining nodal regions for this clinical problem. Yet we wonder: is it optimal—or even rational—to treat the primary and the medi...

Researchers at Osaka University in Japan have identified a key component of physical health associated with response to immunotherapy drugs. Among people with non-small cell lung cancer, higher levels of muscle mass predicted a better response to PD-1 inhibitor immunotherapy. Sarcopenia — the term used to describe low muscle mass levels — appears to reduce the benefits a person receives from immunotherapy cancer treatment. “Sarcopenia at baseline is a significant predictor of worse outcome in patients with advanced NSCLC [non-small cell lung cancer] receiving PD-1 blockade,” the study investigators ...

Authors: Protopapa M, Kouloulias V, Nikoloudi S, Papadimitriou C, Gogalis G, Zygogianni A Abstract Non-small cell lung cancer patients with brain metastases have a multitude of treatment options, but there is currently no international and multidisciplinary consensus concerning their optimal treatment. Local therapies have the principal role, especially in symptomatic patients. Advances in surgery and radiation therapy manage considerable local control. Systemic treatments have shown effect in clinical trials and in real life clinical settings; yet, at present, this is restricted to patients with asymptomatic or st...

Recently, many combination therapies involving an immune checkpoint inhibitor targeting the programmed cell death-1 (PD-1)/programmed cell death-ligand 1 (PD-L1) pathway and another treatment option such as chemotherapy, radiation therapy, and various immunotherapy agents have been explored to improve the response rate and clinical outcomes in various solid tumors including non-small cell lung cancer (NSCLC) [1 –8]. Especially, combination therapy with an indoleamine 2,3-dioxygenase 1 (IDO1) inhibitor and a PD-1/PD-L1 inhibitor is expected to be a novel and effective treatment option and is currently attracting a lot of attention.

Opinion statementNon-small cell lung cancer (NSCLC) accounts for 85% of new lung cancer cases and has 5-year survival rates ranging from 92% in early-stage disease to as low as 13% in locally advanced cases. Radiation therapy is a key component in the treatment repertoire for NSCLC, where it is currently used alone or in combinations with chemotherapy and surgery. Despite the broad use of modern photon radiation techniques, as many as 25% of patients experience isolated locoregional recurrences, and toxicity has been proven to be a limiting factor in many cases. Proton beam therapy (PBT) has emerged as a potential solution...

Advanced non-small cell lung cancer (NSCLC) remains an almost incurable disease, with prognosis significantly improved with the advent of immunotherapy that has increased overall survival (OS) in both first and subsequent lines of therapy. Recently, the availability of more focused radiation delivery in the form of stereotactic body radiation therapy (SBRT) has permitted the treatment of both primary and distant metastases in particular when oligometastatic sites of disease permit aggressive local therapy (e.g.
