AIM: Oligometastatic cancer is being increasingly managed with aggressive local therapy using stereotactic body radiation therapy (SBRT). However, few guidelines exist. We summarize the results of an international survey reviewing technical factors for extracranial SBRT for oligometastatic disease to guide safe management. MATERIALS & METHODS: Seven high-volume centers contributed. Levels of agreement were categorized as strong (6-7 common responses), moderate (4-5), low (2-3) or no agreement...

BACKGROUND: Stereotactic body radiotherapy (SBRT) in pancreatic cancer can be limited by its proximity to organs at risk (OAR). In this analysis, we evaluated the toxicity and efficacy of two different treatment approaches in patients with locally recurrent or oligometastatic pancreatic cancer. MATERIALS AND METHODS: According to the prescription method, patients were divided in two cohorts (C1 and C2). The planning target volume (PTV) was created through a 4 mm expansion of the internal target volume...

BACKGROUND: Colorectal cancer (CRC) often presents as oligometastatic disease. Currently available intensive systemic treatment regimens, including combination chemotherapy and molecular targeted agents, result in tumor response and transient to long-term disease control in a high percentage of patients, thus raising the question of further management. Secondary resection and ablation, e.g. by surgery or radiofrequency may contribute to long-term survival and even be curative or at least allow a relevant chemotherapy-free interval...

PURPOSE: A new development in linac-based intracranial radiosurgery is treatment of multiple targets using single isocenter VMAT, which dramatically reduces treatment time while maintaining high conformality and dose gradient. Our purpose is to translate this technique to extracranial SBRT of oligometastases and address additional challenges such as interplay from motion and setup uncertainties. METHODS: We propose SIDO (Single Isocenter with Distinct Optimizations) planning in which all VMAT arcs share an isocenter but each arc treats only one target...

REVIEW

Stereotactic Body Radiotherapy (SBRT) is a well established therapeutic option for patients affected with peripheral early stage non-small cell lung cancer (NSCLC), given the positive clinical evidence accumulated so far on its efficacy and safety. SBRT is regarded as the best choice for inoperable patients, and could also be offered as an alternative to surgery to selected operable patients. More recently, its use for lung metastases progressively increased, and SBRT is now regarded as a low toxic and highly effective local therapy for lung oligometastases from different primary tumors, especially colorectal cancer...

REVIEW
K Lasithiotakis, O Zoras
Metastasectomy remains the only treatment in malignant melanoma to offer complete pathologic response within a few days of in-hospital stay. It has been historically associated with the highest survival rates in the literature reported for patients of this stage. However, only a minority of patients are amenable to curative resection of distant metastatic disease. This patient group exhibit slow growing oligometastases as indicated by: a. Long disease free interval after treatment of their primary tumours and b...

REVIEW
Julian C Hong, Joseph K Salama
The spectrum hypothesis posits that there are distinct clinical states of metastatic progression. Early data suggest that aggressive treatment of more biologically indolent metastatic disease, characterized by metastases limited in number and destination organ, may offer an opportunity to alter the disease course, potentially allowing for longer survival, delay of systemic therapy, or even cure. The development of stereotactic body radiation therapy (SBRT) has opened new avenues for the treatment of oligometastatic disease...

Anil Nicholas Kurup, Matthew R Callstrom
In the last decade, percutaneous treatment of musculoskeletal (MSK) tumors has become more established in routine clinical care while also undergoing a number of advancements. Ablative techniques to palliate painful skeletal metastases have gained wide acceptance, while goals for ablation have evolved to include local control of oligometastases and desmoid tumors. Bone consolidation or augmentation is now frequently used in conjunction with or instead of ablation of skeletal tumors to stabilize pathologic fractures or prevent further morbidity that could result from fractures caused by tumor progression...

BACKGROUND: Therapeutic approaches to brain metastases include surgery, whole-brain radiotherapy, stereotactic radiosurgery (SRS), and combination therapy. Recently, postoperative or preoperative SRS draws more attention to reduce postoperative recurrence in brain metastases. The goal of this study is to review surgical outcome of patients who had been treated by SRS, and to discuss the effectiveness of preoperative SRS. METHODS: From 2009 to 2015, 174 patients were treated by SRS for brain metastases, and among these 50 patients underwent surgery...

Growing teratoma syndrome is an infrequent presentation of testicular cancer. We present a case of growing teratoma syndrome in a patient who initially presented with clinical stage I nonseminomatous testicular germ cell tumor, who subsequently developed large volume oligometastases to the retroperitoneum, thorax, and thigh. Despite two regimens of chemotherapy, his disease progressed. Complete surgical extirpation of all gross tumors confirmed mature teratoma. An aggressive surgical approach, including postchemotherapy resection of all known metastatic sites, can provide long-term disease-free survival...

INTRODUCTION: The concept of "oligometastasis" has emerged as a basis on which to identify patients with stage IV non-small cell lung cancer (NSCLC) who might be most amenable to curative treatment. Limited data have been available regarding the survival of patients with node-negative oligometastatic NSCLC. PATIENTS AND METHODS: Consecutive patients with advanced NSCLC who attended Kindai University Hospital between January 2007 and January 2016 were recruited to this retrospective study...

Oligometastasis is defined as a transitional state between localized and widespread systemic metastatic cancers. In colorectal cancer, the prognostic factors and prognostic value of preoperative serum carbohydrate antigen 19-9 (CA19-9) and carcinoembryonic antigen (CEA) for patients with colorectal liver oligometastases (CLOM) undergoing hepatic resection have not been well explored. Therefore, the present study included 141 patients with CLOM (≤5 liver metastases) who underwent R0 resection from 2005 to 2012...
