Upper abdominal involvement in recurrent cervical cancer usually occurs as part of systemic disease and is most often amenable to palliative chemotherapy. However, in certain cases in which oligometastatic disease is proven, surgery might be considered. We present a case series of six patients submitted to surgery for upper abdominal oligometastases with cervical origin. The main surgical procedures performed included atypical hepatectomy (in five cases) and splenectomy (in one case). In all cases, the cervical origin of the lesions was revealed by histopathological studies...

BACKGROUND: Oligometastases refers to a state of limited metastatic disease. The use of local ablative therapies to patients with oligometastases can result in durable state of remission or long-term cure. Stereotactic body radiotherapy (SBRT) is a highly conformal radiation technique that delivers ablative doses to the target. The study aimed to evaluate local control (LC) and identify factors associated with poor LC in patients with pulmonary oligometastases treated with SBRT. Primary endpoint of the study was to assess LC; secondary endpoint was to determine factors associated with LC...

BACKGROUND: Several experiences in the literature report SBRT as an effective treatment option for medically inoperable early stage non-small cell lung cancer (NSCLC) and oligometastatic disease. The optimal fractionation schedules and total dose remain controversial. In this study, we evaluated the safety in terms of toxicity and efficacy of using of 8-10 fractions schedules with Helical Tomotherapy (HT) for primary and metastatic lung lesions. METHODS: Between March 2014 and May 2016, a total of 39 patients (median age 72 years, range 26-91) were treated with HT-SBRT for malignant lung lesions: 22 patients with early stage NSCLC, 17 with oligometastases...

As head and neck squamous cell carcinoma (HNSCC) patients with distant metastases (DM) were generally treated only palliatively, the value of screening for DM was usually limited to attempts to avoid extensive locoregional treatment when DM were present pretreatment. Recently, the concept of treating oligometastases, e.g., by metastatectomy or stereotactic body radiotherapy, has been reintroduced for HNSCC and may cause a change in the treatment paradigm. Although whole body 18F-fluoro-2-deoxy-D-glucose positron emission tomography (FDG-PET) combined with computed tomography (CT; WB-FDG-PET/CT) is still the mainstay diagnostic technique, there is a growing body of evidence supporting implementation of whole body magnetic resonance imaging (WB-MRI) as an important diagnostic technique for screening for DM...

Metastatic lung cancer has long been considered incurable, with the goal of treatment being palliation. However, a clinically meaningful number of these patients with limited metastases (approximately 25%) are living long term after definitive treatment to all sites of active disease. These patients with so-called oligometastatic disease likely represent a distinct clinical group who may possess a more indolent biology compared with their more widely metastatic counterparts. Hellman and Weichselbaum proposed the existence of the oligometastatic state, on the basis of the spectrum theory of cancer spread...

BACKGROUND: Recurrent esophageal carcinoma (EC) has a dismal prognosis. However, prior studies showed that selected patients with isolated recurrence may benefit from definitive therapy. The aim of this study was to identify the predictors of postrecurrence survival (PRS) in patients with isolated EC recurrence who were treated with curative intent. METHODS: A retrospective review of a prospective database (1988 to 2015) was performed to identify all recurrent EC patients after curative esophagectomy...

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...
