Esophageal cancer (EC) consists of tumors with a generally poor prognosis, and treatment options for patients with disease recurrence are extremely limited. Due to this poor patient prognosis, the possible treatment toxicity should be carefully balanced against its potential benefit and patient quality of life. Stereotactic body radiotherapy (SBRT) is a rapidly expanding novel technique combining a short treatment time together with high local efficacy and an acceptable toxicity profile. There are no publications thus far presenting data regarding the usage of SBRT utilizing a conventional linear accelerator in locally recurrent EC patients...

Brain metastases are relatively uncommon in gynecological malignancies, and there is limited available data on their management. The present study reports the outcomes of patients with brain metastasis from gynecological malignancies who were treated with stereotactic radiosurgery (SRS). Patients with brain metastasis from a gynecological primary site were treated with SRS using the Cyberknife™ frameless SRS system. Primary lesions were treated with a single fraction of 16-22 Gy. A total of 3 resection cavities were treated with 8 Gy 3 times, meaning a total of 24 Gy, and 1 recurrent lesion was re-irradiated with 5 Gy 5 times, meaning a total of 25 Gy...

Chemotherapy and targeted therapies are effective palliative options for numerous unresectable or metastatic cancers. However, treatment resistance inevitably develops leading to mortality. In a subset of patients, systemic therapy appears to control the majority of tumors leaving 5 or less to progress, a phenomenon described as oligoprogression. Reasoning that the majority of lesions remain responsive to ongoing systemic chemotherapy, we hypothesized that local treatment of the progressing lesions would confer a benefit...

BACKGROUND: The net benefit from local ablative therapy for pulmonary oligometastases remains unknown. The outcomes of stereotactic ablative radiotherapy (SABR) for metastatic lung lesions (MLLs) were analyzed retrospectively and compared with those of SABR for primary lung lesions (PLLs). METHODS: Medical records of patients treated with lung SABR between 2011 and 2014 were retrospectively reviewed. Basic patient, lesion and treatment characteristics were compared using the Pearson chi-square test for categorical and Mann-Whitney U test for continuous variables...

BACKGROUND: The aim of the present study is to evaluate the impact of metastases-directed stereotactic body radiotherapy in two groups of oligometastatic prostate cancer (PC) patients: oligorecurrent PC and oligoprogressive castration-resistant PC (oligo-CRPC). METHODS: Inclusion criteria of the present multicentre retrospective analysis were: (1) oligorecurrent PC, defined as the presence of 1-3 lesions (bone or nodes) detected with choline positron emission tomography or CT plus bone scan following biochemical recurrence; (2) oligo-CRPC, defined as metastases (bone or nodes) detected after a prostatic-specific antigen rise during androgen deprivation therapy (ADT)...

AIM: For selected patients with brain metastases (BMs), the role of stereotactic radiosurgery (SRS) or fractionated stereotactic radiotherapy (SFRT) is well recognized. The recent introduction of flattening filter free (FFF) delivery during linac-based SRS or SFRT allows shorter beam-on-time, improving patients' comfort and facility workflow. Nevertheless, limited experiences evaluated the impact of FFF linac-based SRS and SFRT in BMs treatment. Aim of the current study was to analyze SRS/SFRT linac-based FFF delivery for BMs in terms of dosimetric and early clinical results...

Salvage surgery is a relatively new entity in thoracic surgery and oncology. Salvage resection after radiotherapy refers to surgery as only remaining therapeutic option in patients who were treated with high-dose stereotactic radiotherapy (SRT) for early-stage lung cancer or full-dose chemoradiation for locally advanced lung cancer. Indications include locally progressive tumors, recurrent local or locoregional disease, or specific complications after radiotherapy such as lung abscesses or infected, necrotic cavities...

The incidence of brain metastases from hepatocellular carcinoma (BMHCC) is becoming more frequent than that of the past as a result of prolonged survival of patients with HCC. Compared with brain metastases from other types of cancer, BMHCC tends to exhibit a high incidence of intracerebral hemorrhage (ICH) and poor liver function. Unfortunately, the prognosis is extremely poor for patients with BMHCC owing to the limited treatment selection. Currently, optimal treatment requires multidisciplinary approaches including surgery, whole-brain radiation therapy and stereotactic radiosurgery...

Objective: Using diagnostic pathological methods during surgery is a valuable means of determining the appropriate management for patients. Application of Frozen Section in CNS surgeries might face challenges due to friability of brain tissue and its relative inaccessibility. Various studies have evaluated the diagnostic acuity of frozen section compared to gold standard but results have been quite inconsistent. We conducted the present study to evaluate the accuracy of cryostat in diagnosing central nervous system tumors compared to the Gold Standard method...

Proteinaceous inclusions, called Lewy bodies, are used as a pathological hallmark for Parkinson's disease (PD). Lewy bodies contain insoluble α-synuclein (aSyn) and many other ubiquitinated proteins, suggesting a role for protein degradation system failure in the PD pathogenesis. Indeed, proteasomal dysfunction has been linked to PD but commonly used in vivo toxin models, such as 6-OHDA or MPTP, do not have a significant effect on the proteasomal system or protein aggregation. Therefore, we wanted to study the characteristics of a proteasomal inhibitor, lactacystin, as a PD model on young and adult mice...

BACKGROUND: Twelve years ago, a randomized trial demonstrated that a radiosurgery boost added to whole-brain radiotherapy (WBRT) improved intracerebral control (IC) in patients with one to three cerebral metastases. Overall survival (OS) was improved only in the subgroup of patients with a single metastasis but not in the entire cohort. The present study compared both regimens in a different scenario outside a randomized trial. METHODS: A total of 252 patients with one to three cerebral metastases were included...

Stereotactic body radiotherapy (SBRT) is an alternative to surgery for patients with early stage non-small cell lung cancer (NSCLC) who are inoperable due to comorbid disease or who refuse surgery. SBRT results in an excellent local control rate of more than 90%, which is comparable to surgery, while short and long-term overall toxicity is low. Surgically treated patients are often more extensively staged pre-operatively, e.g. with endobronchial ultrasound and/or mediastinoscopy, and typically undergo intra-operative lymph node dissection or sampling...

BACKGROUND: There is an increasing need for evidence-based efficiency in providing a growing amount of cancer care. One example of a quality gap is the use of multiple-fraction palliative radiation for patients with advanced cancer who have uncomplicated bone metastases; evidence suggests similar pain outcomes for treatment regimens with a lower burden of treatments. METHODS: During the first phase of quality improvement work, we used RAND/UCLA appropriateness methodology to understand how radiation oncologists at one academic medical center rate the appropriateness of different treatment regimens for painful uncomplicated bone metastases...

Here, we present the case of a pediatric patient with newly diagnosed hepatocellular carcinoma causing central biliary obstruction and persistently elevated bilirubin of 3.0-4.3 mg/dl despite placement of bilateral internal-external biliary drains. The tumor was not resectable, and the patient was not a candidate for liver transplant due to nodal disease, for chemotherapy due to hyperbilirubinemia, or for local therapies aside from stereotactic body radiotherapy (SBRT). In this report, we discuss the successful use of SBRT in the management of this patient, and its role in allowing the patient to become a candidate for additional therapies...
