BACKGROUND: Sequential anthracyclines and taxanes are standard adjuvant chemotherapy for patients with high-risk axillary node-positive breast cancer. We compared a sequential to a concurrent regimen in high-risk node-negative early breast cancer. METHODS: Patients were eligible if they had tumours >2 cm or T1c with two of the following characteristics: no oestrogen receptor (ER) and progesterone receptor (PR) expression, histological grade III, Ki67 >40% and vascular, lymphovascular or perineural invasion...

INTRODUCTION: Surveys state a widespread use of complementary and alternative medicine (CAM) in patients with malignant diseases. CAM methods might potentially interfere with the metabolization of tumor-specific therapy. However, there is little communication about CAM use in hematology/oncology patients between patients, CAM providers, and oncologists. PATIENTS AND METHODS: A self-administered questionnaire was handed out to all patients attending to the hematology/oncology outpatient clinic of Regensburg University Hospital...

PURPOSE: The Imaging and Radiation Oncology Core Houston (IROC-H) (formerly the Radiological Physics Center) has reported varying levels of agreement in their anthropomorphic phantom audits. There is reason to believe one source of error in this observed disagreement is the accuracy of the dose calculation algorithms and heterogeneity corrections used. To audit this component of the radiotherapy treatment process an independent dose calculation tool is needed. METHODS: Monte Carlo multiple source models for Elekta 6MV and 10MV therapeutic x-ray beams were commissioned based on measurement of central axis depth dose data for a 10 x 10 cm(2) field size and dose profiles for a 40 x 40 cm(2) field size...

BACKGROUND: Some elderly cancer patients, even with good Eastern Cooperative Oncology Group performance status (ECOG-PS), have poor survival outcomes and cannot tolerate standard therapy. Few studies have detailed the associations between the G8 screening tool, ECOG-PS, and overall survival (OS) in such patients. METHODS: Cancer patients, aged 70 years or older, were assessed for G8 and classified into three groups according to their G8 score: <11 as the low score group, 11-14 as the intermediate score group, and >14 as the high score group...

Current therapies for medulloblastoma were introduced primarily in the 1980s and consist of predominantly cytotoxic, nontargeted approaches. Mortality from medulloblastoma remains significant. In addition, many survivors suffer from severe treatment-related effects of radiation and cytotoxic chemotherapy. Further intensification of nonspecific therapy is unlikely to offer additional benefits, because survival rates have reached a plateau. Recent publications in medulloblastoma have revolved largely around the recognition that medulloblastoma per se does not exist, but rather, that there are a group of histologically similar but clinically and molecularly distinct entities that have been grouped under that rubric...

Development of novel therapies for CNS tumors requires reliable assessment of response and progression. This requirement has been particularly challenging in neuro-oncology for which contrast enhancement serves as an imperfect surrogate for tumor volume and is influenced by agents that affect vascular permeability, such as antiangiogenic therapies. In addition, most tumors have a nonenhancing component that can be difficult to accurately quantify. To improve the response assessment in neuro-oncology and to standardize the criteria that are used for different CNS tumors, the Response Assessment in Neuro-Oncology (RANO) working group was established...

Glioblastoma (GBM) is a rare tumor and one of the most challenging malignancies to treat in all of oncology. Although advances have been made in the treatment of GBM, encouraging outcomes typically are not observed; patients diagnosed with these tumors generally have a dismal prognosis and poor quality of life as the disease progresses. This review summarizes the clinical presentation of GBM, diagnostic methods, evidentiary basis for the current standards of care, and investigational approaches to treat or manage GBM...

Recent breakthroughs in next-generation sequencing technology and complementary genomic platforms have transformed our capacity to interrogate the molecular landscapes of human cancers, including childhood brain tumors. Numerous high-throughput genomic studies have been reported for the major histologic brain tumor entities diagnosed in children, including interrogations at the level of the genome, epigenome, and transcriptome, many of which have yielded essential new insights into disease biology. The nature of these discoveries has been largely platform dependent, exemplifying the usefulness of applying different genomic and computational strategies, or integrative approaches, to address specific biologic and/or clinical questions...

Glioblastoma (GBM) is the most lethal form of brain tumor and remains a large, unmet medical need. This review focuses on recent advances in the neurosciences that converge with the broader field of immuno-oncology. Recent findings in neuroanatomy provide a basis for new approaches of cellular therapies for tumors that involve the CNS. The ultimate success of immunotherapy in the CNS will require improved imaging technologies and methods for analysis of the tumor microenvironment in patients with GBM. It is likely that combinatorial approaches with targeted immunotherapies will be required to exploit the vulnerabilities of GBM and other brain tumors...

Patients with cancer are frequently affected by spinal metastases. Treatment is palliative, with the principle goals of pain relief, preservation of neurologic function, and improvement in quality of life. In the past decade, we have witnessed a dramatic change in the treatment paradigms due to the development of improved surgical strategies and systemic and radiation therapy. The most important change to these paradigms has been the integration of spinal stereotactic radiosurgery (SSRS), allowing delivery of tumoricidal radiation doses with sparing of nearby organs at risk...

Modern imaging techniques, particularly functional imaging techniques that interrogate some specific aspect of underlying tumor biology, have enormous potential in neuro-oncology for disease detection, grading, and tumor delineation to guide biopsy and resection; monitoring treatment response; and targeting radiotherapy. This brief review considers the role of magnetic resonance imaging and spectroscopy, and positron emission tomography in these areas and discusses the factors that limit translation of new techniques to the clinic, in particular, the cost and difficulties associated with validation in multicenter clinical trials...

The use of vitamins and minerals to prevent cancer as well as their supportive use in oncological patients is widespread and often occurs without the knowledge of the treating physician. Beyond general recommendations with regard to a balanced and healthy diet, no evidence exists supporting the use of vitamins and minerals in the prevention of cancer. Furthermore, the diet of oncological patients should contain vitamins and minerals of the same quantity as for healthy individuals. In particular, there is currently no rationale for a high-dosage administration of antioxidants...

The basis of any complementary therapy should be the recommendation of a healthy lifestyle (diet, nutrition, exercise, stress-reduction), and appropriate self-help techniques (e. g. thermotherapy, herbal OTC-products) aimed at releasing the patients' most debilitating symptoms. For therapy-resistant or strong symptoms, more invasive interventions or medical treatments with an acceptable evidence base can be used (e. g. acupuncture for cancer pain, herbal prescriptions). The effects of any complementary intervention should be controlled for a period of six weeks after its administration...

There are a vast number of complementary and alternative medicines (CAM) in oncology. Also patients' needs for information on these methods are growing. Helping patients to classify and evaluate CAM methods is a challenge. The Cancer Information Service at the German Cancer Research Center has developed a benefit-risk-assessment based on evidence-based medicine and individual patient traits: To rate a CAM's benefit, the scientific evidence and the patient's therapeutic goals have to be taken into account. To estimate its risks, both, the method itself and the patient's status of health must be considered...

Adenoid cystic carcinoma of the head and neck area is a rare malignant tumor with acceptable short-term but mediocre long-term prognosis. Radical tumor excision with clear resection margins, and sometimes resection of the facial nerve due to perineural growth, remains the fundamental therapy. We present 3 distinct clinical cases and discuss the current therapeutic options with special focus on plastic-reconstructive techniques. For reconstruction, the full armament of local and free flaps, as well as prosthetics, may be necessary...

We conducted an economic evaluation of intravenous (IV) vs subcutaneous (SC) trastuzumab for the treatment of patients with early breast cancer (EBC). Data of patients receiving adjuvant IV trastuzumab at our institute in 2014 were used to study three different treatment scenarios: 1) IV trastuzumab, 2) SC trastuzumab, and 3) IV trastuzumab during chemotherapy followed by SC trastuzumab. Our cohort included 114 patients with a median weight of 63.75 kg. Scenario 2 was the most time-saving treatment, with 71...
