Junaid Raja, Johannes M Ludwig, Scott N Gettinger, Kurt A Schalper, Hyun S Kim
BACKGROUND: Immunotherapy is at the forefront of modern oncologic care. Various novel therapies have targeted all three layers of tumor biology: tumor, niche, and immune system with a range of promising results. One emerging class in both primary and salvage therapy is oncolytic viruses. This therapy offers a multimodal approach to specifically and effectively target and destroy malignant cells, though a barrier oncoviral therapies have faced is a limited therapeutic response to currently delivery techniques...

BACKGROUND: Standard therapy for stage III non-small cell lung cancer with chemotherapy and conventional radiation has suboptimal outcomes. We hypothesized that a combination of surgery followed by stereotactic body radiation therapy (SBRT) would be a safe alternative. METHODS: Patients with stage IIIA (multistation N2) or IIIB non-small cell lung cancer were enrolled from March 2013 to December 2015. The protocol included transcervical extended mediastinal lymphadenectomy (TEMLA) followed by surgical resection, 10 Gy SBRT directed to the involved mediastinum/hilar stations and/or positive surgical margins, and adjuvant systemic therapy...

Recurrent malignant gliomas (RMGs) are difficult to control, and no standard protocol has been established for their treatment. At our institute, we have often treated RMGs by tumor-selective particle radiation called boron neutron capture therapy (BNCT). However, despite the cell-selectivity of BNCT, brain radiation necrosis (BRN) may develop and cause severe neurological complications and sometimes death. This is partly due to the full-dose X-ray treatments usually given earlier in the treatment course. To overcome BRN following BNCT, recent studies have used bevacizumab (BV)...

Prostate-specific membrane antigen (PSMA) targeting agents comprise a rapidly emerging class of radiopharmaceuticals for prostate cancer diagnostic imaging. Unlike most other PSMA agents with a urea-backbone, CTT1057 is based on a phosphoramidate scaffold that irreversibly binds to PSMA. We conducted a first-in-human Phase I study of CTT1057 in patients with localized and metastatic prostate cancer. Methods: Two patient cohorts were recruited. Cohort A were patients with biopsy-proven localized prostate cancer preceding radical prostatectomy, and cohort B were patients with metastatic castrate resistant prostate cancer...

Spinal muscular atrophy is a genetic motor neuron disease that leads to progressive muscular atrophy and muscle weakness. In December 2016, the Food and Drug Administration, and in June 2017, the European Medicines Agency approved the antisense oligonucleotide nusinersen for treatment of spinal muscular atrophy. Nusinersen has to be repeatedly administered intrathecally. Due to the clinical features of SMA, the application of the ASO by lumbar puncture can be challenging in symptomatic patients considering the frequently observed scoliosis, previous spine fusion surgeries, joint contractures, and respiratory insufficiency...

Stereotactic body radiation therapy (SBRT) allows the targeting of high doses of radiation with steep dose gradients. Vertebral fracture is increasingly recognized as an adverse event after SBRT; however, no sacral fractures have been observed after SBRT. We report an extremely rare case of sacral insufficiency fracture after SBRT.

Patient safety is an essential component of quality of care, especially when the complexity of care has reached extreme levels. Currently achieving this safety is considered a basic strategy of the National Health System. Nuclear Medicine departments have certain peculiarities that make them special in terms of patient safety, with situations that go beyond the common healthcare practice of other departments. Namely, that both encapsulated and non-encapsulated ionizing radiation is used in daily practice, and numerous groups of professionals must be coordinated to undertake positron emission tomography (PET) specifically, from the clinical management unit itself, and from other departments of the hospital (as well as companies outside the hospital itself and the Public Health System)...

BACKGROUND: Transbronchial cryobiopsy (TBCB) of the lung parenchyma is a minimally invasive alternative for surgical lung biopsy in interstitial lung disease (ILD) patients. Drawbacks are the nondiagnostic rate and complication risk of pneumothorax and bleeding. Fluoroscopy is the current guidance tool for TBCB, which is limited by 2D imaging and a radiation dose for the patient. Confocal laser endomicroscopy (CLE) is a high-resolution imaging technique that provides immediate feedback during bronchoscopy about the elastin fiber network of peripheral lung areas...
