BACKGROUND: Locally advanced uterine cervical cancer (LAUCC) with lateral tumor extension may not always be covered adequately by conventional intracavitary brachytherapy (ICBT). Hybrid intracavitary and interstitial brachytherapy (HBT) seems to be an effective alternative by improving anatomy-oriented dose optimisation. The purpose of this study was to report initial clinical result for LAUCC treated by HBT. METHODS: Between January 2012 and November 2015, 42 patients with LAUCC (T1b2-4a) were treated with primary radiation therapy including HBT...

Merkel cell carcinoma (MCC) is a rare, aggressive skin malignancy that has a propensity for local recurrence and metastasis to the lymph nodes. In this case report, we discuss a 54-year-old female with rheumatoid arthritis (RA) who had received treatment with prednisone (15 mg/day) for symptom relief and management. The patient visited our hospital with complaints of a nodule in right preauricular area. Computed tomography (CT) scans revealed no distant metastasis. The patient underwent surgical resection and histopathological evaluation of the nodule led to the diagnosis of MCC...

Urothelial cancer is one of the most common malignancies; after relapse or disease progression available therapeutic options are limited. We analyze efficacy and toxicity of local treatment on metastases using stereotactic body radiation therapy (SBRT) in selected patients with oligometastatic disease from urothelial cancer. A significant percentage of treated lesions achieved local control, with a promising overall response rate. OBJECTIVES: to analyze efficacy and toxicity of local treatment on metastases using stereotactic body radiation therapy (SBRT) in selected patients with oligometastatic disease from urothelial cancer...

BACKGROUND: A biopsy of first recurrence or metastatic disease is recommended to re-evaluate oestrogen receptor status in patients with breast cancer and to select appropriate treatment. However, retesting for oestrogen receptor status with rebiopsy is not always feasible, depending on lesion location and the risk associated with biopsy, and in these cases clinicians continue to treat patients according to the oestrogen receptor status of the primary tumour. Consequently suboptimal therapy might be offered to these patients...

BACKGROUND: Body surface area (BSA) can reflect metabolic rate that might normalize dosing of chemotherapeutics across widely variable weights within a species. The current BSA formula for dogs lacks height, length, and body condition. HYPOTHESIS: Computed tomography (CT) imaging will allow inclusion of morphometric variables in allometric modeling of BSA in dogs resulting in an improved formula for BSA estimation. ANIMALS: Forty-eight dogs from 4 institutions with whole-body CT images...

INTRODUCTION: Previous studies have shown that simultaneous treatment with sorafenib, a vascular endothelial growth factor receptor tyrosine-kinase inhibitor (VEGFR-TKI), and radiation therapy (RT) can cause gastrointestinal hemorrhage (GH) as an adverse event. However, it is known that sorafenib monotherapy can cause GH. Thus it is essential to know the association between the radiation field and the bleeding site. CASE PRESENTATION: We report a case of bleeding ulcers on the ascending colon in a patient undergoing simultaneous RT and sorafenib administration...

Literature has recently highlighted the enormous scientific interest on the relationship between the gut microbiota and colon cancer, and how the use of some selected probiotics can have a future impact on the adverse events which occur during this disease. Although there is no clear evidence to claim that probiotics are effective in people with cancer, recent reviews have found that probiotics can significantly reduce the incidence of diarrhea and the average frequency of daily bowel movements. However, most of this evidence needs to be more clinically convincing and further discussed...

REVIEW
Marcher Thompson, Kenneth E Rosenzweig
Stereotactic body radiation therapy (SBRT) is an effective and well tolerated treatment for early stage non-small cell lung cancer (NSCLC). The high doses used in thoracic SBRT can sometimes cause adverse effects ranging from mild fatigue and transient esophagitis to fatal events such as pneumonitis or hemorrhage. Efforts continue to expand in both the utility of this technique as well as our understanding of the mechanisms of the adverse effects it can cause. In this review, we discuss the current literature regarding the potential mechanisms, dosimetric constraints and toxicities associated with SBRT alone and in conjunction with definitive chemoradiotherapy and immunotherapy...

BACKGROUND: Prior randomized studies have shown a survival benefit using combined androgen deprivation therapy (ADT) and radiation therapy for intermediate-risk prostate cancer. However, these studies either used low doses of radiation (66.6 Gy to isocenter) or imaged guidance was not available. This study reports the initial differences for high dose image guided radiation with or without ADT. METHODS: From 2012 to 2014, 56 patients were treated with and 60 patients without 6 months of ADT (N = 116) in our phase III randomized trial for intermediate-risk prostate cancer...

Fecal microbiota transplantation (FMT) is a novel strategy for the therapy of dysbiosis-associated disorders via modulation of the gut microbiota. Intestinal dysbiosis is associated not only with digestive disorders, but also with a variety of extra-digestive disorders. A worldwide increasing number of FMT can be expected in the future as well as an increase in adverse events. We describe the case of a patient with chronic radiation colitis that developed adhesion ileus 2 days after FMT. Since these problems never occured before and the short time interval favours a causality, we speculate about FMT-induced alterations in gut motility causing a "trapping" of the small intestine in an adhesion and other mechanisms beyond "pure" coincidence...
