Anti-endothelin drugs in solid tumors
2010
Importance of the field: The endothelin (ET) axis, which includes the biological functions of ETs and their receptors, has played a physiological role in normal tissue, acting as a modulator of vasomotor tone, tissue differentiation and development, cell proliferation and hormone production. Interestingly, it also functions in the growth and progression of various tumors. Several researchers have identified the blockade of the ET-1 receptor as a promising therapeutic approach. Areas covered in this review: The clinical investigation of an orally bioavailable ET antagonist, atrasentan, in prostate cancer, is encouraging. In this neoplasia, it has shown antitumor activity, bone metastasis con…
Treatment guidelines of metastatic colorectal cancer in older patients from the French Society of Geriatric Oncology (SoFOG)
2020
International audience; Background: Several guidelines dedicated to metastatic colorectal cancer (mCRC) are available. Since 2013 no recent guidelines are specifically dedicated to older patients and based on a systematic review. Materials and methods: A multidisciplinary Task Force with digestive oncologists, geriatricians and methodologists from the SoFOG was formed in 2016 to update recommendations on medical treatment of mCRC based on a systematic review of publications from 2000 to 2018. Search strategy has followed a standardized protocol from the formulation of clinical questions and definition of a search algorithm to the selection of complete articles for recommendations. Results: …
Endoscopic and surgical resection of T1a/T1b esophageal neoplasms: A systematic review
2013
AIM: To investigate potential therapeutic recommendations for endoscopic and surgical resection of T1a/T1b esophageal neoplasms. METHODS: A thorough search of electronic databases MEDLINE, Embase, Pubmed and Cochrane Library, from 1997 up to January 2011 was performed. An analysis was carried out, pooling the effects of outcomes of 4241 patients enrolled in 80 retrospective studies. For comparisons across studies, each reporting on only one endoscopic method, we used a random effects meta-regression of the log-odds of the outcome of treatment in each study. “Neural networks” as a data mining technique was employed in order to establish a prediction model of lymph node status in superficial …
Feasibility and Diagnostic Impact of Fluorescence-Based Diagnostic Laparoscopy in Hepatocellular Carcinoma: A Case Report
2002
Fluorescence-based diagnostic techniques are an evolving field in the staging of hepatologic and gastroenterologic malignancies. The method aims at improved accuracy in the detection of locoregional and distant metastases. In hepatocellular carcinoma, detection of metastases is of utmost importance, because advanced tumors preclude curative surgical therapy. We present here our first experience of fluorescence-based diagnostic laparoscopy in a patient with hepatocellular carcinoma. We performed diagnostic laparoscopy in a 76-year-old woman who presented with a tumor of the liver and increased serum levels of alpha-fetoprotein. For photosensitization, 5-aminolevulinic acid (20 mg/kg bodyweig…
Impact of margin status on long-term results of liver resection for hepatocellular carcinoma: single-center time-to-recurrence analysis
2020
Occult metastasis from the initial tumor and a de novo second primary hepatocellular carcinoma (HCC) were recognized as the main causes for the onset of early and late HCC recurrence, after liver resection (LR). This study aims to compare the time to recurrence after LR for HCC in which a margin ≤ 1 mm or > 1 mm was achieved. A single-center retrospective study involving 256 patients was conducted from June 2005 to June 2019. HCC patients resected with a radical surgical approach were investigated and stratified into groups A (resection margins ≤ 1 mm) and B (> 1 mm), as measured on final pathologic assessment. Kaplan–Meier estimators were used to estimate the probability of recurrenc…
Pulmonary metastasectomy in colorectal cancer: a prospective study of demography and clinical characteristics of 543 patients in the Spanish colorect…
2013
Objectives To capture an accurate contemporary description of the practice of pulmonary metastasectomy for colorectal carcinoma in one national healthcare system. Design A national registry set up in Spain by Grupo Espanol de Cirugia Metastasis Pulmonares de Carcinoma Colo-Rectal (GECMP-CCR). Setting 32 Spanish thoracic units. Participants All patients with one or more histologically proven lung metastasis removed by surgery between March 2008 and February 2010. Interventions Pulmonary metastasectomy for one or more pulmonary nodules proven to be metastatic colorectal carcinoma. Primary and secondary outcome measures The age and sex of the patients having this surgery were recorded with the…
A systematic review and meta-analysis comparing surgical and oncological outcomes of upper rectal, rectosigmoid and sigmoid tumours.
2021
Abstract Aim Management paradigms for tumours from the sigmoid colon to the lower rectum vary significantly. The upper rectum (UR) represents the transition point both anatomically and in treatment protocols. Above the UR is clearly defined and managed as colon cancer and below is managed as rectal cancer. This study compares outcomes between sigmoid, rectosigmoid and UR tumours to establish if differences exist in operative and oncological outcomes. Methods Electronic databases were searched for published studies with comparative data on peri-operative and oncological outcome for upper rectal and sigmoid/rectosigmoid (SRS) tumours treated without neoadjuvant radiation. The search adhered t…

Current Surgical Treatment Standards for Esophageal and Esophagogastric Junction Cancer
2020
A number of different surgical techniques for the treatment of cancer of the esophagus and the esophagogastric junction have been proposed. Guidelines generally recommend a transthoracic approach for esophageal cancer, including Siewert type I tumors. In tumors of the proximal esophageal third, transthoracic esophagectomy may be extended to a three-field approach, including resection of cervical lymph nodes. However, the choice between transthoracic esophagectomy with intrathoracic anastomosis (Ivor Lewis esophagectomy) and the three-incision approach with cervical esophago-gastrostomy (McKeown esophagectomy) remains controversial, with guidelines varying among different countries. Furtherm…
Dissection of lymph node metastases in esophageal cancer.
2011
There has been much recent debate regarding the best surgical procedure to treat esophageal cancer, in particular with regard to the optimum extent of lymphadenectomy to improve survival while minimizing morbidity. No results obtained by prospective, randomized studies on the comparison of radical esophagectomy and extended lymphadenectomy with limited or less invasive resections following neoadjuvant therapy with regard to perioperative morbidity and prognosis are available to date. Until now, there has been no evidence suggesting the usefulness of sentinel lymph node navigation in esophageal cancers, regardless of the cell type. Furthermore, the question as to the benefits and risks of tw…
