A 70's man had been treated with gemcitabine(GEM)and nab-paclitaxel(nabPTX)combination for advanced pancreatic tail cancer with splenic invasion and liver metastases. However, the primary lesion was not controlled, then intensity-modulat- ed radiation therapy(76.5 Gy/17 Fr)was performed for primary lesion. Three grown hypovascular liver metastases were detected by follow-up EOB-MRI and PET-computed tomography(CT)imaging with 18F-FDG. Unfortunately, these lesions were not detected by intravenous injection of contrast media with CT nor ultrasonography...

BACKGROUND: Perivascular epithelioid cell tumors (PEComas) are rare mesenchymal tumors occurring in various anatomic regions. Although diagnostic criteria and treatment management are not established, current treatment options consist of surgery and chemotherapy including mTOR inhibitors. Stereotactic body radiation therapy (SBRT) is a non-invasive ablative treatment which has shown excellent control rates for more common types of unresectable liver tumors and metastases. In this report we present a rare case of PEComa of the liver that was treated by stereotactic radiotherapy followed by resection...

In the past five years, the utilization of PET/CT guidance is more commonly used for cancer patients undergoing biopsy and ablations at this NCI-Designated Cancer Center. The interventional use of PET/CT imaging requires nurses to have a thorough understanding of the mechanisms involved in order to provide the best care in an environment that is safe for patients and staff. Evidence suggests cohesive care and safe practice measures are achieved when patients actively participate and understand their care. This article will discuss how a collaborative, patient-centered approach in caring for oncologic patients undergoing PET/CT interventions is necessary for achieving quality patient outcomes...

Purpose: Transcatheter hepatic artery embolization therapy is a minimally invasive alternative for treating inoperable liver cancer but recurrence is frequent. Multifunctional agents, however, offer an opportunity for tumor eradication. In this study, we were aim to synthesized poly (lactic-co-glycolic acid) (PLGA) microspheres encapsulating hollow CuS nanoparticles (HCuSNPs) and paclitaxel (PTX) that were then labeled with radioiodine-131 (131I) to produce 131I-HCuSNPs-MS-PTX. This compound combines the multi-theranostic properties of chemotherapy, radiotherapy and photothermal therapy...

Patients with oligometastatic disease (OMD) often have controllable symptoms, and cures are possible. Technical improvements in surgery and radiotherapy have introduced the option of metastasis-directed ablative therapies as an adjunct or alternative to standard-of-care systemic therapies. Several clinical trials and registries are investigating the benefit of these therapeutic approaches across several cancer sites. This requires that patients are correctly included and followed with appropriate imaging. This article discusses the evidence and offers recommendations for the implementation of standard-of-care (Response Evaluation Criteria in Solid Tumours measurements on computed tomography [CT], magnetic resonance imaging [MRI] and bone scintigraphy) and advanced imaging modalities (functional, metabolic and radionuclide targeted) for identifying and following up patients with OMD...

A 65-year-old woman with metastatic lung cancer was referred for CT-guided cryoablation of a right adrenal metastasis. For cryoablation, probes were placed into the adrenal region. FDG PET/CT 3 months later showed new activity in hepatic segment 6 initially suspected to be metastasis. Proximity of the hepatic lesion to the adrenal metastasis was a strange coincidence and prompted review of imaging from the cryoablation. CT showed the probe entered the liver, and postablation image demonstrated injury to the liver adjacent to the adrenal metastasis...

BACKGROUND: Minimally invasive surgery, stereotactic radiotherapy, and radiofrequency ablation are commonly proposed in the case of pulmonary colorectal-metastasis as alternatives to conventional open surgery. Preoperative imaging assessment by computed tomography (CT) scan and fluorodeoxyglucose positron emission tomography (FDG-PET) are critical to guide oncologic radical treatment. Our aim was to investigate the accuracy of CT and FDG-PET for the evaluation of the number of pulmonary colorectal metastases and thoracic lymph nodal involvement (LNI)...

BACKGROUND: Clinical data that support stereotactic body radiation therapy (SBRT) metastatic malignant melanoma (MM) are limited. Furthermore, functional imaging with 18F-fludeoxyglucose positron emission tomography (PET) may offer a more accurate post-SBRT assessment. Therefore, we assessed the clinical outcomes and metabolic response of metastatic MM after SBRT. METHODS AND MATERIALS: Patients with MM who were treated with SBRT and had pre- and post-PET scans (>1) were included in this study...

We have recently developed a flexible catheter electrode used for bronchoscopic radiofrequency ablation (RFA). Two patients with nonsurgical stage IA peripheral lung cancer and 1 with lung metastasis underwent treatment with flexible catheter RFA utilizing navigation bronchoscopy. Chest computed tomography (CT) and positron emission tomography/CT (PET/CT) were performed before and after RFA to assess the ablation response of the patients. One patient's tumor had no prior PET uptake and therefore no follow-up PET was obtained...

In recent years, there have been many reports about the efficacy of stenting for central bronchial stenosis. When central bronchial stenosis is due to metastasis of a malignant tumor to the trachea and/or bronchi (endobronchial metastasis: EM), it is classified as "narrow EM" and "broad EM." [1] We managed two patients in whom bilateral stent placement was required for narrow and broad EM arising from colorectal cancer. Case 1: In September 2011, a 66-year-old man underwent low anterior resection for advanced colorectal cancer associated with unresectable liver metastasis...
