Multimodal treatment approaches are indispensable for patients with advanced-stage cancer, while radiation therapy has been established as essential part of therapeutic approaches and has been introduced as a better option to face challenges, such as, local relapse or oligometastatic disease. The mere insight of the concept of oligometastases, proposed for the first time in the middle 1990s, led to the hypothesis that this condition may be cured using local ablative weapons. This hypothesis has already been demonstrated by surgical ablative techniques...

BACKGROUND: Patients with melanoma brain metastases (MBM) have been excluded from trials evaluating immunotherapy in melanoma. As such, immunotherapy's role in MBM is poorly understood, particularly in combination with radiotherapy. METHODS: The National Cancer Database was queried for patients with MBM receiving brain radiotherapy. They were classified according to immunotherapy receipt. Multivariate Cox regression was performed to identify factors associated with survival...

REVIEW
Grainne M O Kane, Jennifer J Knox
Pancreatic adenocarcinoma (PDAC) remains a highly fatal disease that is increasing in incidence. PDAC can be classified according to resectability status with 3 nonmetastatic groups defined: resectable, borderline resectable, and locally advanced PDAC (LAPC). Delineating these subtypes is important with the optimal treatment approach dictated by high-quality CT imaging and multidisciplinary team discussion. Patients with LAPC are thought unresectable and are therefore rarely cured. In these patients, chemotherapy remains the mainstay of treatment...

PURPOSE: To assess intra- and inter-fractional motions of liver and lung tumors using active breathing control (ABC). METHODS AND MATERIALS: Nineteen patients with liver cancer and 15 patients with lung cancer treated with stereotactic body radiotherapy (SBRT) were included in this retrospective study. All patients received a series of three CTs at simulation to test breath-hold reproducibility. The centroids of the whole livers and of the lung tumors from the three CTs were compared to assess intra-fraction variability...

PURPOSE: Diffuse intrinsic pontine glioma (DIPG) remains the main cause of death in children with brain tumors. Given the inefficacy of numerous peripherally delivered agents to treat DIPG, convection enhanced delivery (CED) of therapeutic agents is a promising treatment modality. The purpose of this study was to determine which MR imaging type provides the best discrimination of intratumoral heterogeneity to guide future stereotactic implantation of CED catheters into the most cellular tumor regions...

REVIEW
Megumi Asai, Walter J Scott
Pulmonary resection after pneumonectomy is a reasonable option in selected patients. Wedge resection for single peripheral metachronous disease has the best outcome with 5-year survival as high as 63%. Current and predicted postoperative cardiopulmonary reserve should be evaluated carefully. Stereotactic body radiotherapy is a promising alternative for inoperable patients.

Non-small-cell lung cancer (NSCLC) is the most common malignancy in industrialized countries, with a 5-year survival rate of only ~15%, as the majority of the patients have advanced-stage disease at diagnosis and the treatment options are limited. Squamous cell carcinoma the second most frequent type of NSCLC and is closely associated with cigarette smoking. We herein present the case of a 72-year-old male smoker, diagnosed with stage IV squamous cell lung carcinoma, with a solitary brain metastasis. After the diagnosis, stereotactic radiotherapy was performed on the brain metastasis...

Brain metastases are the most common intracranial tumors in adults, accounting for more than 50% of all such cases. The approach to and management of brain metastases have evolved significantly in recent years due to several reasons. These include advances in neurosurgical and radiotherapeutic techniques, improved systemic therapy options offering better systemic and intracranial disease control and prolongation of survival as a result of these improvements, making side-effects of proposed therapies (e.g. neurocognitive decline from whole brain radiotherapy) an important consideration...

PURPOSE: The purpose of the present study was the optimization of dose calculation for intracranial stereotactic radiosurgery. METHODS: We evaluated the Singular Value Decomposition (SVD) analysis as a novel optimization technique. Our approach to dose distribution optimization was to recover estimates of minibeams weights from well-defined provisional dose matrices. The dose delivered by a set of minibeams is formulated as a matrix equation. We studied the influence of dose matrix and voxel dimensions on the conditioning of stereotactic radiotherapy inverse problem...

Metastatic involvement of the pancreas occurs in 5% of patients affected by advanced malignancies. Surgical resection has been reported by number of authors as a valuable option to improve disease control, in particular in patients with limited disease burden and favourable histotypes; however, the benefit of this procedure has been questioned due to patient selection, technical challenges and relevant risk of perioperative mortality and severe complications. In the present study, a cohort of surgically unfit patients affected by a solitary metastasis in the pancreas from various primary tumours received stereotactic radiotherapy with an ablative dose schedule, obtaining promising local and distant disease progression-free delay with minor toxicity...

BACKGROUND: We compared the functional outcome and influential factors of two standard treatment modalities for central cerebral metastases: electrophysiological-controlled microsurgical resection (MSR) and stereotactic radiotherapy/stereotactic radiosurgery (SRT/SRS). METHODS: We performed a database search for central metastasis treatments during the period from January 2008 to September 2012 in two clinical registers: 1) register for intraoperative neuromonitoring (Department of Neurosurgery), and 2) prospective database for SRT/SRS (Department of Radiotherapy)...

Volumetric Modulated Arc Therapy (VMAT) techniques for fractioned stereotactic brain radiotherapy (FSBRT) can achieve highly conformal dose distribution to intracranial lesions. However, they can potentially increase the dose to hippocampus (H) causing neurocognitive toxicity during the first four months after irradiation. The purpose of this study was to assess the feasibility of hippocampal-sparing (HS) treatment plans in 22 patients with brain metastasis treated with VMAT technique. Firstly, we retrospectively analyzed hippocampal doses in all 22 VMAT original (not hippocampal-sparing, NHS) plans...

BACKGROUND: Colorectal cancer (CRC) rarely metastasizes to the brain. The incidence of cerebral metastases (CM) is estimated between 1 and 3%. Given the improved survival from advanced CRC as a result of surgical and oncological advances, it is anticipated that the incidence of patients with CM from CRC will rise over the next few years. The aim of this article was to systematically review the treatment options and outcome of patients with CM from CRC. METHODS: PubMed and Medline databases were examined using the search words or MESH headings "colorectal" "cancer/carcinoma/adenocarcinoma", "cerebral"/"brain" and "metastases/metastasis"...

BACKGROUND: Radiotherapy for pancreatic cancer has two major challenges: (I) the tumor is adjacent to several critical organs and, (II) the mobility of both, the tumor and its surrounding organs at risk (OARs). A treatment planning study simulating stereotactic body radiation therapy (SBRT) for pancreatic tumors with both the internal target volume (ITV) concept and the tumor tracking approach was performed. The two respiratory motion-management techniques were compared in terms of doses to the target volume and organs at risk...

OBJECTIVE: Visualising the gold marker (GM) in CT and MRI is critical, especially for registration in high-precision radiotherapy. GM sizes vary. Large markers are easily visualised in MRI. Small GMs show fewer artefacts in CT but are harder to detect in MRI because the signal is influenced by metal in MRI. Therefore, we compared MRI visualisation between linearly placed new iron-containing marker and non-iron containing marker. METHODS: Twenty-seven patients underwent CT/MRI fusion-based intensity-modulated radiotherapy...
