Although radiotherapy is commonly used to treat cancer, its beneficial outcome is frequently hampered by the radiation resistance of tumor cells and adverse reactions in normal tissues. Mechanisms of cell-to-cell communication and how intercellular signals are translated into cellular responses, have become topics of intense investigation, particularly within the field of radiobiology. A substantial amount of evidence is available demonstrating that both gap junctional and paracrine communication pathways can propagate radiation-induced biological effects at the intercellular level, commonly referred to as radiation-induced bystander effects (RIBE)...

Breast cancers arising in young women are biologically more aggressive, and most of these patients are candidates to receive aggressive treatments that include the use of chemotherapy. As most of these tumors express the hormone receptors (i.e., luminal disease), these patients are also candidates to adjuvant endocrine therapy. Chemotherapy-induced amenorrhea showed to be prognostic in young patients with luminal breast cancer. However, the role of ovarian function suppression (OFS) in addition to standard adjuvant treatments has been largely debated over the past years...

OBJECTIVES: Pancreatic cancer is a difficult-to-treat disease with a persistently high mortality rate. We evaluated dose distribution simulation with respiratory-gated carbon-ion pencil beam scanning (C-PBS) with a simultaneous integrated boost (SIB) to increase tumor dose, sparing organs at risk (OARs). METHODS: Using four-dimensional computed tomography (4DCT) data of 12 patients, we delineated gross tumor volume (GTV) and two clinical target volumes (CTVs). To consider beam range intrafractional uncertainty, we calculated field-specific target volumes (FTVs), from which two planning target volumes (PTVs) were generated...

BACKGROUND: Desmoid tumors are benign but locally aggressive non-malignant tumors derived from fibroblasts. Surgery, chemotherapy, and radiation therapy have been the mainstay of treatment, but recurrence is common and side effects can result in significant morbidity. In this case series, we highlight our experiences performing treatments in the thigh, including strategies for optimizing ablation size and safety. CASE PRESENTATION: Since December 2014, 14 magnetic resonance-guided focused ultrasound (MRgFUS) treatments for desmoid tumors were performed at our institution in seven patients...

Optic nerve sheath meningioma (ONSM) is typically diagnosed based on clinical suspicion and imaging characteristics and is most often treated with radiation. Historically, biopsy, optic nerve sheath decompression, and debulking surgeries have been avoided for fear of optic nerve vascular disruption and tumor spread into the orbit. This is a case of a 48-year-old man who presented with unilateral optic disc edema, declining visual acuity, and a visual field defect. Despite an initial improvement with acetazolamide, his vision subsequently worsened...

Malignant solitary fibrous tumor (MSFT) is a well-described entity, from which heterologous differentiation is extremely rare. We encountered a case of MSFT with rhabdomyosarcomatous differentiation in a 56-year-old man. This patient presented with a large mass in his posterior thigh. He had been treated with chemoradiation for sarcoma involving the cervical spine, right femoral head, and both lungs 6 months earlier. A wide excision was performed. The mass measured 10.6 cm and showed a fish-flesh cut surface with necrotic foci...

Non-small cell lung cancer (NSCLC) is the leading cause of cancer-related death worldwide. Fifty percent of the cases are metastatic at diagnosis and about 20% develop brain metastasis. The brain involvement represents a negative prognostic factor. However, some patients could benefit from locoregional treatments of metastatic foci and experience an unexpected long survival or healing. In the previous years some classifications were proposed to identify patients' prognostic category, according to stage of the primary tumor, the timing of metastases occurrence (synchronous or metachronous) and the number of metastatic sites...

Pancreatic cancer (PC) is one of the most deadly and quickly fatal human cancers with a 5-year mortality rate close to 100%. Its prognosis is very poor, mainly because of its hostile biological behavior and late onset of symptoms for clinical diagnosis; these bring limitations on therapeutic interventions. Factors contributing for the difficulties in treating PC include: high rate of drug resistance, fast metastasis to different organs, poor prognosis and relapse of the tumor after therapy. After being approved by US FDA 1997, Gemcitabine (Gem) is the first line and the gold standard drug for all stages of advanced PC till now...

The majority of women with epithelial ovarian cancer present with advanced stage disease and there is a critical need for novel drugs and treatment strategies to improve outcomes. Trabectedin is a unique cytotoxic agent with a complex mechanism of action. It binds to guanines in the N2 position in the minor groove of DNA and its cytotoxicity involves DNA repair pathways and transcription regulation. Trabectedin's activity is also related to the drug-induced changes of the tumor microenvironment. It has been shown to improve progression-free survival in combination with pegylated liposomal doxorubicin in patients with platinum-sensitive relapsed ovarian cancer...

Since arsenic trioxide was first approved as the front line therapy for acute promyelocytic leukemia 25 years ago, its anti-cancer properties for various malignancies have been under intense investigation. However, the clinical successes of arsenic trioxide in treating hematological cancers have not been translated to solid cancers. This is due to arsenic's rapid clearance by the body's immune system before reaching the tumor site. Several attempts have henceforth been made to increase its bioavailability toward solid cancers without increasing its dosage albeit without much success...
