BACKGROUND: In the present study we review and discuss the current evidence and suggest how to proceed in the management of oligometastatic disease in upper gastrointestinal cancer. METHODS: An electronic search of the PubMed database for relevant articles was performed. RESULTS: Both the search for 'oligometastasis', 'oligometastases', 'oligometastatic', 'oligometastatic disease' as well as 'esophageal' and 'esophageal cancer' and the search for 'oligometastasis', 'oligometastases', 'oligometastatic', 'oligometastatic disease' as well as 'gastric', 'gastric cancer', 'stomach', and 'stomach cancer' yielded very few studies...

We conducted a multicenter prospective study to clarify the efficacy and safety of surgery and imatinib for liver oligometastasis of gastrointestinal stromal tumors. Eligible gastrointestinal stromal tumor patients were enrolled in the surgery trial or the imatinib trial. Primary endpoints were recurrence-free survival and progression-free survival, respectively. The trials were prematurely terminated due to amendment of guidelines for adjuvant imatinib therapy and low patient accrual. In the surgery trial, all the six patients showed hepatic recurrence: median recurrence-free survival was 145 days (range: 62-1366 days)...

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...

The oligometastatic state has been proposed as an intermediate stage of cancer spread between localized disease and widespread metastases. With improvements in diagnostic modalities such as functional imaging, oligometastatic prostate cancer is being diagnosed with greater frequency than ever before. Furthermore, the paradigm for treatment of advanced prostate cancers is shifting toward a more aggressive approach. Many questions surround the understanding of the process and consequences of oligometastasis, meaning that the contemporary literature offers a wide variety of definitions of oligometastatic prostate cancer...

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...

Stereotactic body radiotherapy (SBRT) has emerged as the standard treatment for medically inoperable early-staged non-small cell lung cancer (NSCLC). The local control rate after SBRT is over 90%. Some forms of tumour motion management and image-guided radiation delivery techniques are the prerequisites for fulfilment of its goal to deliver a high radiation dose to the tumour target without overdosing surrounding normal tissues. In this review, the current strategies of tumour motion management will be discussed, followed by an overview of various image-guided radiotherapy (RT) systems and devices available for clinical practice...

Oligometastic progression (or solitary metastases) can justify ablative treatment for metastatic treatment. When such a strategy is discussed, it is important to notice that definition of oligometastases is not consensual both in terms of clinical presentation than on the biological basis. Does a specific biological background truly exist and are there markers that could predict for additional occult disease and its oligo or polymetastatic profile in individuals with demonstrated oligometastasis. This article provides a summary of the state of the art in this field and highlights some current areas of controversies...

INTRODUCTION: Clinical evidence for patients with synchronous brain oligometastatic non-small-cell lung carcinoma is limited. We aimed to summarize the clinical data of these patients to explore the survival prognostic factors for this population. METHODS: From September 1995 to July 2011, patients with 1-3 synchronous brain oligometastases, who were treated with stereotactic radiosurgery (SRS) or surgical resection as the primary treatment, were identified at Shanghai Chest Hospital...

Oligometastasis refers to a state of limited metastatic disease burden, in which surgical or ablative treatment to all known visible metastases holds promise to extend survival or even effect cure. Stereotactic body radiotherapy is a form of radiation treatment capable of delivering a high biologically effective dose of radiation in a highly conformal manner, with a favorable toxicity profile. Enthusiasm for oligometastasis ablation, however, should be counterbalanced against the limited supporting evidence...

The aim of this study was to retrospectively compare the treatment efficacy of systemic chemotherapy combined with sequential CT-guided radiofrequency ablation (Chemo-RFA) to chemotherapy alone (Chemo-only) in the management of nasopharyngeal carcinoma (NPC) with liver metastasis. Between 2003 and 2011, 328 NPC patients diagnosed with liver metastasis at Sun Yat-sen University Cancer Center were enrolled. One-to-one matched pairs between Chemo-RFA group with the Chemo-only group were generated using propensity score matching...

BACKGROUND: The selection of patients for oligometastasis-directed ablative therapy remains a challenge. The authors report on clinical and molecular predictors of survival from a stereotactic body radiotherapy (SBRT) dose-escalation trial for oligometastases. METHODS: Patients who had from 1 to 5 metastases, a life expectancy of >3 months, and a Karnofsky performance status of >60 received escalating SBRT doses to all known cancer sites. Time to progression, progression-free survival, and overall survival (OS) were calculated at the completion of SBRT, and clinical predictors of OS were modeled...

We herein present a case of a 76-year-old gentleman, where prostate-specific membrane antigen positron emission tomography-computed tomography (PSMA PET-CT) was used to accurately detect prostate cancer (PCa), pelvic lymph node (LN) metastasis in the setting of biochemical recurrence following definitive treatment for PCa. The positive PSMA PET-CT result was confirmed with histological examination of the involved pelvic LNs following pelvic LN dissection.

Metastases-directed therapy via surgery or stereotactic body radiotherapy (SBRT) has become the de facto standard of care in the United States and abroad despite a lack of high quality prospective, randomized trials. Oligometastatic tumors may behave in an inherently more indolent manner secondary to underlying biologic characteristics, including discrepant microRNA expression patterns. This biologic discrepancy suggests that historic improvements in survival observed in retrospective series may stem from the inherent biology of oligometastases and selection biases as opposed to advances in novel localized treatments...
