The aim of this document is to provide general information about sentinel lymph node detection in breast cancer patients.

Endoscopic surveillance for non-dysplastic Barrett's esophagus (BE) is contentious and its cost effectiveness unclear.

An accurate and complete pathology report is critical for the optimal management of cutaneous melanoma patients. Protocols for the pathologic reporting of melanoma have been independently developed by the Royal College of Pathologists of Australasia (RCPA), Royal College of Pathologists (United Kingdom) (RCPath), and College of American Pathologists (CAP). In this study, data sets, checklists, and structured reporting protocols for pathologic examination and reporting of cutaneous melanoma were analyzed by an international panel of melanoma pathologists and clinicians with the aim of developing a common, internationally agreed upon, evidence-based data set. The International Collaboration on Cancer Reporting cutaneous melanoma expert review panel analyzed the existing RCPA, RCPath, and CAP data sets to develop a protocol containing "required" (mandatory/core) and "recommended" (nonmandatory/noncore) elements. Required elements were defined as those that had agreed evidentiary support at National Health and Medical Research Council level III-2 level of evidence or above and that were unanimously agreed upon by the review panel to be essential for the clinical management, staging, or assessment of the prognosis of melanoma or fundamental for pathologic diagnosis. Recommended elements were those considered to be clinically important and recommended for good practice but with lesser degrees of supportive evidence. Sixteen core/required data elements for cutaneous melanoma pathology reports were defined (with an additional 4 core/required elements for specimens received with lymph nodes). Eighteen additional data elements with a lesser level of evidentiary support were included in the recommended data set. Consensus response values (permitted responses) were formulated for each data item. Development and agreement of this evidence-based protocol at an international level was accomplished in a timely and efficient manner, and the processes described herein may facilitate the development of protocols for other tumor types. Widespread utilization of an internationally agreed upon, structured pathology data set for melanoma will lead not only to improved patient management but is a prerequisite for research and for international benchmarking in health care.

The following recommendations for post-polypectomy endoscopic surveillance should be applied only after a high quality baseline colonoscopy with complete removal of all detected neoplastic lesions.1 In the low risk group (patients with 1 - 2 tubular adenomas < 10 mm with low grade dysplasia), the ESGE recommends participation in existing national screening programmes 10 years after the index colonoscopy. If no screening programme is available, repetition of colonoscopy 10 years after the index colonoscopy is recommended (strong recommendation, moderate quality evidence). 2 In the high risk group (patients with adenomas with villous histology or high grade dysplasia or ≥10 mm in size, or ≥ 3 adenomas), the ESGE recommends surveillance colonoscopy 3 years after the index colonoscopy (strong recommendation, moderate quality evidence). Patients with 10 or more adenomas should be referred for genetic counselling (strong recommendation, moderate quality evidence). 3 In the high risk group, if no high risk adenomas are detected at the first surveillance examination, the ESGE suggests a 5-year interval before a second surveillance colonoscopy (weak recommendation, low quality evidence). If high risk adenomas are detected at first or subsequent surveillance examinations, a 3-year repetition of surveillance colonoscopy is recommended (strong recommendation, low quality evidence).4 The ESGE recommends that patients with serrated polyps < 10 mm in size with no dysplasia should be classified as low risk (weak recommendation, low quality evidence). The ESGE suggests that patients with large serrated polyps (≥ 10 mm) or those with dysplasia should be classified as high risk (weak recommendation, low quality evidence).5 The ESGE recommends that the endoscopist is responsible for providing a written recommendation for the post-polypectomy surveillance schedule (strong recommendation, low quality evidence).

Colorectal cancer is one of the most important causes of cancer mortality worldwide. This article reviews the available evidence for optimum management of stage II and III colorectal cancer, with respect to staging, surgical and adjuvant neoadjuvant treatment.

Colorectal cancer (CRC) incidence has increased during the past decades in Spain, being the first malignant tumour in incidence. Observed mortality for CRC is mainly due to liver and lung metastases. The only curative treatment is surgery; new surgical techniques and neoadjuvant treatments have increased the number of surgery candidate patients. Patients should be managed with a multidisciplinary approach that includes imaging techniques, chemotherapy, surgery and pathological assessment. As an answer to this approach, a group of pathology experts interested on CRC liver metastases aimed to review the diagnosis and prognosis of liver mestastases and developed practical recommendations for its assessment. The expert group revised the current literature and prepared questions to be discussed based on available evidence and on their clinical practise. As a result, recommendations for the assessment of tumour regression of liver metastases are proposed, which could be implemented in oncology centres allowing assessment standardisation for these patients. Prospective multi-center studies to evaluate these recommendations validity will further contribute to improve the standard care of CRC liver metastases patients.

In this updated SCLC guidelines the authors have reviewed the "SEOM recommendation" for diagnosis and treatment of patients, including consideration for elderly and unfit patients. We hope the SCLC guidelines will be useful for residents and oncology teams.

Head and neck cancer represents 5 % of oncologic cases in adults. Early stage treatments are local with surgery and/or radiotherapy. For locally advanced stages, treatment requires radiotherapy combined with platinum-based drugs or cetuximab. Induction chemotherapy should be considered for selected cases. In the case of metastatic disease, adjuvant or palliative treatment is based on platinum agents and cetuximab.

Nasopharyngeal carcinoma cases are not frequently encountered in our environment. Local stages are treated with radiotherapy. For advanced local stages, the association of chemotherapy with radiotherapy improves the rates of survival. In the case of metastatic disease stages, treatment requires platinum-based chemotherapy and patients may achieve a long survival time.

The purpose of this article is to update our previous work on the treatment and follow-up in early breast cancer. In this new version we have classified a treatment by immunohistochemistry subtypes of breast cancer. Latest advances in the management of this disease have been compiled, either in the adjuvant and neoadjuvant setting or chemotherapy and hormonal treatment. This review is presented in an easy way for oncologist, fellows and for other specialties.

Lung cancer remains the most commonly diagnosed cancer worldwide and the leading cause of cancer-related mortality. More than 80 % of all newly diagnosed cases of lung cancer are non-small cell lung cancer (NSCLC). Despite recent advances, 40 % of patients still have advanced disease at the moment of diagnosis. Clinical information, pathological diagnosis and molecular assessment are needed to guide the systemic therapy, whereas discussion within an experienced team is key to adequately select the most appropriate multidisciplinary strategies. The purpose of this article is to provide updated recommendations for the management of these patients.

The histopathological examination of a prostate biopsy is the basis of prostate cancer diagnostics. Prostate cancer grade and extent of cancer in the diagnostic biopsy are important determinants of patient management. Quality of the prostate biopsy and its processing may influence the outcome of the histopathological evaluation. Further, an unambiguous and concise pathology reporting is essential for an appropriate clinical decision process. Since our initial report in 2003, there have been several practice changes, including the increased uptake of follow-up biopsies of patients who are under active surveillance, increasingly taken under guidance of MRI, or who underwent a prostate-sparing therapy. Therefore, we investigated the literature on the current pathology practices and recommendations with regard to prostate biopsy processing and reporting, both at initial diagnosis and in the context of follow-up biopsies in order to update our guidelines on the optimal processing and reporting of prostate biopsies.

Approximately half of patients with colorectal cancer present with liver metastases during the course of their disease, which directly affect prognosis and is responsible for two thirds of deaths related to the disease. In the last two decades the treatment of liver metastases from colorectal cancer (CRCLM) provided significant gain in survival when all treatment options are available to the patient. In this context, surgical treatment remains as the only chance of cure, with five-year survival rates of 25-58%. However, only 1/4 of the patients have resectable disease at diagnosis. For this reason, one of the key points in the current management of patients with CRCLM is the development of strategies that facilitate complete resection of liver lesions. The advent and refinement of ablative methods have expanded the possibilities of surgical therapy. The emergence of new chemotherapy regimens and the introduction of targeted therapies has provided high response rates and has permanently altered the management of these patients. The multimodal therapy and the involvement of different medical specialties has increasingly enabled CRCLM treatment to approached the ideal treatment, i.e., an individualized one. Based on an extensive review of literature and on experience from some of the most important specialized centers of Brazil, the São Paulo Liver Club began a process of multi-institutional discussions that resulted in the recommendations that follow. These recommendations, however, are not intended to be absolute, but useful tools in the therapeutic decision process for this complex group of patients.

The diagnosis and treatment of osteosarcoma should be performed by an experienced multidisciplinary team. Considering it is a systemic disease, chemotherapy is essential for long-term success. The drugs most commonly used are: cisplatin, adriamycin, high-dose methotrexate, ifosfamide, etoposide, and, more recently, mifamurtide. The neoadjuvant chemotherapy allows to know tumour chemosensitivity and getting the main prognostic factor: the percentage of tumour necrosis. In addition to chemotherapy, it is important to conduct surgical resection of primary tumour with wide margins, and in disseminated disease also to attempt resection of pulmonary metastasis.

Colorectal cancer (CRC) is the most common malignant tumor in Western countries. Despite efforts made to implement screening programmes for early detection and treatment, still half of the patients present or will eventually develop distant metastasis. Management of advanced CRC should be discussed within an experienced multidisciplinary team, to adequately select the most appropriate systemic therapeutic option, as well as the optimal way to integrate it with surgical procedures when indicated. Disease localization and extent, resectability of primary and metastatic disease, tumor biology and dynamics, clinical symptoms, personal preferences and patient's ability to tolerate intensive chemotherapy or extensive surgical procedures are the key factors to properly design a customized treatment plan. The aim of the current manuscript is to provide synthetic practical guidelines regarding therapeutic options for advanced CRC.

The histologic examination of endoscopic biopsies or resection specimens remains a key step in the work-up of affected inflammatory bowel disease (IBD) patients and can be used for diagnosis and differential diagnosis, particularly in the differentiation of UC from CD and other non-IBD related colitides. The introduction of new treatment strategies in inflammatory bowel disease (IBD) interfering with the patients' immune system may result in mucosal healing, making the pathologists aware of the impact of treatment upon diagnostic features. The European Crohn's and Colitis Organisation (ECCO) and the European Society of Pathology (ESP) jointly elaborated a consensus to establish standards for histopathology diagnosis in IBD. The consensus endeavors to address: (i) procedures required for a proper diagnosis, (ii) features which can be used for the analysis of endoscopic biopsies, (iii) features which can be used for the analysis of surgical samples, (iv) criteria for diagnosis and differential diagnosis, and (v) special situations including those inherent to therapy. Questions that were addressed include: how many features should be present for a firm diagnosis? What is the role of histology in patient management, including search for dysplasia? Which features if any, can be used for assessment of disease activity? The statements and general recommendations of this consensus are based on the highest level of evidence available, but significant gaps remain in certain areas.

The first European Association of Urology (EAU) guidelines on bladder cancer were published in 2002 [1]. Since then, the guidelines have been continuously updated.

The new German S3 guideline "Colorectal Carcinoma" was created as part of the German Guideline Program in Oncology of the Association of the Scientific Medical Societies in Germany, the German Cancer Society and the German Cancer Aid under the auspices of the German Society for Digestive and Metabolic Diseases and replaces the guideline from 2008. With its evidence-based treatment recommendations, the guideline contains numerous updates and detailed definitions regarding the diagnosis and treatment of colon and rectal cancer. In particular, consensus-based recommendations regarding early detection, preoperative diagnostic method selection, and the use of interventional radiological treatment methods are detailed. The guideline also includes quality indicators so that standardized quality assurance methods can be used to optimize patient-related processes.The present article discusses the significance of the current recommendations for radiological diagnosis and treatment and is intended to enhance the quality of patient information and care by increasing distribution.
