Prevention of venous thromboembolism (VTE) in cancer patients remains controversial in most clinical settings.

The current third consensus on the systemic treatment of non-small-cell lung cancer (NSCLC) builds upon and updates similar publications on the subject by the Central European Cooperative Oncology Group (CECOG), which has published such consensus statements in the years 2002 and 2005 (Zielinski CC, Beinert T, Crawford J et al. Consensus on medical treatment of non-small-cell lung cancer--update 2004. Lung Cancer 2005; 50: 129-137). The principle of all CECOG consensus is such that evidence-based recommendations for state-of-the-art treatment are given upon which all participants and authors of the manuscript have to agree (Beslija S, Bonneterre J, Burstein HJ et al. Third consensus on medical treatment of metastatic breast cancer. Ann Oncol 2009; 20 (11): 1771-1785). This is of particular importance in diseases in which treatment options depend on very particular clinical and biologic variables (Zielinski CC, Beinert T, Crawford J et al. Consensus on medical treatment of non-small-cell lung cancer--update 2004. Lung Cancer 2005; 50: 129-137; Beslija S, Bonneterre J, Burstein HJ et al. Third consensus on medical treatment of metastatic breast cancer. Ann Oncol 2009; 20 (11): 1771-1785). Since the publication of the last CECOG consensus on the medical treatment of NSCLC, a series of diagnostic tools for the characterization of biomarkers for personalized therapy for NSCLC as well as therapeutic options including adjuvant treatment, targeted therapy, and maintenance treatment have emerged and strongly influenced the field. Thus, the present third consensus was generated that not only readdresses previous disease-related issues but also expands toward recent developments in the management of NSCLC. It is the aim of the present consensus to summarize minimal quality-oriented requirements for individual patients with NSCLC in its various stages based upon levels of evidence in the light of a rapidly expanding array of individual therapeutic options.

The diagnosis and treatment of disseminated intravascular coagulation (DIC) remain extremely controversial.

Radioactive material licensing and radiation safety are discussed given the unique requirements of microsphere brachytherapy. A general, team-based quality assurance program is reviewed to provide guidance for the creation of the local procedures. Finally, recommendations are given on how to deliver the current state of the art treatments and directions for future improvements in the therapy.

A recent study on the use of cancer antigen 125 (CA-125) in follow-up of patients with epithelial ovarian cancer after complete response on primary treatment is critically reviewed. As it has been suggested to refrain from CA-125 altogether, this European Society of Gynaecologic Oncology report has also reviewed possible disadvantages, even possible harm, and potentially missed opportunities when such policy would be implemented. It is concluded that indeed routine use of CA-125 does not provide patient benefit in survival or quality of life. However, there may be other reasons for monitoring CA-125, which are discussed in this review. It is noted that the lack of benefit of CA-125 monitoring has only been proven for a specific subset of ovarian cancer patients with serous histology and frequent follow-up visits including imaging and in a clinical environment where, particularly, surgery for recurrent disease and clinical studies on new second-line agents will not be considered. A special warning is issued not to stop tumor marker follow-up in other than epithelial ovarian cancers and in follow-up of patients who not have been treated with chemotherapy.

An American Society of Clinical Oncology (ASCO) focused update updates a single recommendation (or subset of recommendations) in advance of a regularly scheduled guideline update. This document updates one recommendation of the ASCO Guideline Update on Chemotherapy for Stage IV Non-Small-Cell Lung Cancer (NSCLC) regarding switch maintenance chemotherapy.

Approximately 30% of colorectal cancers exhibit familial clustering. Currently, we recognize a number of different types of polyps and polyposis syndromes that are classified according to the histology of the typical polyp. We differentiate between adenomas, hyperplastic, and hamartomatous polyps as well as between syndromes that are manifested by 10-100 or above 100 polyps. It is essential to distinguish between these syndromes as each has a different mode of presentation, spectrum of signs and symptoms and cancer risk associated with them. With the knowledge accumulating, we now have the tools to lower the risk of cancer by performing specific screening programs that are tailored to each syndrome. In these guidelines we focus on the non-adenomatous polyps, hyperplastic and hamartomatous polyposis syndromes. We outline the importance of multi-sector team work that includes the family practitioner, gastroenterologist, pathologist, genetic counselor, surgeon, and social worker.

Approximately 30% of colorectal cancers exhibit familial clustering. We recognize different types of polyps and polyposis syndromes that are classified according to the histological diagnosis. We differentiate between adenomas, hyperplastic, and hamartomatous polyps as well as between syndromes that are manifested by 10-100 or above 100 polyps. Only about 1% of colorectaL cancers (CRCs) are due to adenomatous polyposis syndrome. It is essential to distinguish between these syndromes as each has a different mode of presentation, spectrum of signs and symptoms and cancer risk. With the knowledge that is accumulating we now have the tools to lower the risk of cancer by performing specific screening programs that are tailored to each syndrome specifically. We present the Israeli guidelines for management of adenomatous polyposis, based on the American and European experience and consensus. We outline the importance of mutti-sectorial team work that includes the family practitioner, gastroenterologist, pathologist, genetic counselor, surgeon and social worker.

The incidence of primary cutaneous melanoma has been increasing dramatically for several decades. Melanoma accounts for the majority of skin cancer-related deaths, but treatment is nearly always curative with early detection of disease. In this update of the guidelines of care, we will discuss the treatment of patients with primary cutaneous melanoma. We will discuss biopsy techniques of a lesion clinically suspicious for melanoma and offer recommendations for the histopathologic interpretation of cutaneous melanoma. We will offer recommendations for the use of laboratory and imaging tests in the initial workup of patients with newly diagnosed melanoma and for follow-up of asymptomatic patients. With regard to treatment of primary cutaneous melanoma, we will provide recommendations for surgical margins and briefly discuss nonsurgical treatments. Finally, we will discuss the value and limitations of sentinel lymph node biopsy and offer recommendations for its use in patients with primary cutaneous melanoma.

Retinoblastoma is the most common intraocular tumor in children. The diagnosis is usually established by the ophthalmologist on the basis of fundoscopy and US. Together with US, high-resolution MRI has emerged as an important imaging modality for pretreatment assessment, i.e. for diagnostic confirmation, detection of local tumor extent, detection of associated developmental malformation of the brain and detection of associated intracranial primitive neuroectodermal tumor (trilateral retinoblastoma). Minimum requirements for pretreatment diagnostic evaluation of retinoblastoma or mimicking lesions are presented, based on consensus among members of the European Retinoblastoma Imaging Collaboration (ERIC). The most appropriate techniques for imaging in a child with leukocoria are reviewed. CT is no longer recommended. Implementation of a standardized MRI protocol for retinoblastoma in clinical practice may benefit children worldwide, especially those with hereditary retinoblastoma, since a decreased use of CT reduces the exposure to ionizing radiation.

This article is part of a combined publication that expresses the current view of the European Society of Gastrointestinal Endoscopy (ESGE) about endoscopic ultrasound (EUS)-guided sampling in gastroenterology, including EUS-guided fine needle aspiration (EUS-FNA) and EUS-guided trucut biopsy (EUS-TCB), of submucosal tumors, diffuse esophageal/gastric wall thickening, pancreatic solid masses and cystic-appearing lesions, mediastinal lesions unrelated to lung or esophageal cancer, cancer of the esophagus, stomach, and rectum, lymph nodes of unknown origin, adrenal gland masses, and focal liver lesions. False-positive cytopathological results and needle tract seeding are also discussed. The present Clinical Guideline describes the results of EUS-guided sampling in the different clinical settings, considers the role of this technique in patient management, and makes recommendations on circumstances that warrant its use. A two-page executive summary of evidence statements and recommendations is provided. A separate Technical Guideline describes the general technique of EUS-guided sampling, particular techniques to maximize the diagnostic yield depending on the nature of the target lesion, and sample processing. The target readership for the Clinical Guideline mostly includes gastroenterologists, oncologists, internists, and surgeons while the Technical Guideline should be most useful to endoscopists who perform EUS-guided sampling.

Hepatocellular carcinoma (HCC) is one of the leading causes of cancer death not only in Japan but also worldwide. Clinical practice guidelines for HCC were first published in 2001 by the European Society of Study of the Liver (EASL) followed by the American Association for the Study of Liver Disease (AASLD) published in 2005 and updated in 2010. However, these guidelines have proven to be somewhat unsuitable for Japanese patients. In 2005, supported by the Japanese Ministry of Health, Labour and Welfare, evidence-based clinical practice guidelines for HCC were compiled in Japan. In 2009, a revised version of evidence-based guidelines was published. Based on both 'evidence-based' guidelines and the consensus of an expert panel on HCC, the Japan Society of Hepatology (JSH) published the Consensus-Based Clinical Practice Manual in 2007 and updated in 2010. In this article, the 2010 updated version of this manual, especially issues on prevention, surveillance, pathology, diagnosis, staging, and treatment algorithm are summarized.

The latest tumour, lymph node and metastasis (TNM) classification by the International Association for the Study of Lung Cancer (IASLC), based on the analysis of patients from all over the world, has incorporated changes in the descriptors, especially those regarding tumor size, while proposing new group staging. A new lymph node map has also been developed with the intention of facilitating the classification of the "N" component. SEPAR recommends using this new classification. As for the procedures recommended for staging, in addition to the generalized use of computed tomography (CT), it points to the role of positron emission tomography (PET) or image fusion methods (PET/CT), which provide a better evaluation of the mediastinum and extrathoracic metastases. Endobronchial ultrasound (EBUS) and esophageal ultrasound (EUS) for obtaining cytohistological samples have been incorporated in the staging algorithm, and it emphasizes the importance of precise re-staging after induction treatment in order to make new therapeutic decisions. Comment is made on the foreseeable incorporation in the near future of molecular staging, and systematic lymph node dissection is recommended with the intention of making a more exact surgical-pathological classification.

Breast conservation is a safe and effective alternative to mastectomy for the majority of women with early-stage breast cancer. Adjuvant radiation therapy lowers the risk of recurrence within the breast and also confers a survival benefit. Although acute side effects of radiation therapy are generally well tolerated; efforts are ongoing to minimize the long-term side effects of radiation, most prominently atherosclerotic heart disease. Efforts to minimize radiation therapy are also underway. They include omitting treatment altogether in the elderly and using accelerated, hypofractionated whole-breast irradiation, and accelerated partial-breast irradiation. Several randomized studies are ongoing to determine the efficacy, safety, and appropriate patients for these shorter treatments.

Our aim is to present a summary of the 2010 version of the European Association of Urology (EAU) guidelines on the treatment of advanced, relapsing, and castration-resistant prostate cancer (CRPC).
