Robot-assisted and conventional minimally invasive esophagectomy are associated with better postoperative results compared to hybrid and open transth…
2021
BACKGROUND Currently 4 surgical techniques are performed for transthoracic esophagectomy (open esophagectomy (OE), hybrid esophagectomy (HE), conventional minimally invasive esophagectomy (MIE) and robot assisted minimally invasive esophagectomy (RAMIE). Aim of this study was to compare these 4 different esophagectomy approaches regarding postoperative complications and short term oncologic outcomes. METHODS Between 2008 and 2019, consecutive patients who underwent esophagectomy with gastric conduit reconstruction were included in this single center study. The primary outcome of this study was the incidence of postoperative complications. RESULTS Overall 422 patients (OE (n = 107), HE (n = …
Comparisons of Submental and Groin Vascularized Lymph Node Flaps Transfer for Breast Cancer-Related Lymphedema
2018
Background:. The vascularized groin and submental lymph node (VGLN and VSLN) flaps are valuable options in the treatment of lymphedema. This study was to compare outcomes between VGLN and VSLN transfers for breast cancer–related lymphedema. Methods:. Between January 2008 and December 2016, VGLN and VSLN transfers for upper limb lymphedema were compared including flap characteristics, flap elevation time, complications, and limb circumference changes. Results:. All flaps survived. Similar vein (2.6 versus 3.2 mm; P = 0.3) and artery diameter (2.1 versus 2.8 mm; P = 0.3) and number of lymph nodes (3 versus 4; P = 0.4) were found between VGLN and VSLN groups, respectively. Circumferential redu…
Nationwide Analysis on Surgical Staging Procedures and Systemic Treatment for Patients With Endometrial Cancer in Germany
2012
ObjectiveIn 2009 and 2006, the Arbeitsgemeinschaft Gynäkologische Onkologie evaluated therapeutic approaches for endometrial carcinoma (EC) in Germany.Methods and MaterialsA questionnaire was developed and sent to 775 German gynecologic departments in 2009 (500 in 2006). The results of the questionnaires were compared with each other and with the recommendations of the Arbeitsgemeinschaft Gynäkologische Onkologie’s guideline. Subgroup analyses were performed, dividing the participating centers into small and large centers and into centers with less and more experience with EC.ResultsResponses were available in 33.3% in 2009 and 35.8% in 2006. Comparing 2009 with 2006, it became apparent tha…
Sentinel Lymph Node Biopsy in Patients With Melanoma
2010
Abstract Introduction and objectives The incidence of melanoma is currently increasing worldwide. One of the factors influencing disease prognosis is the presence of regional lymph node metastases. Sentinel lymph node biopsy attempts to identify subclinical lymph node metastasis as a prognostic factor in the disease. The aim of this study was to analyze differences between patients with melanoma for whom positive or negative results were obtained in sentinel lymph node biopsy and to assess the impact of the technique on disease prognosis. Material and methods Sentinel lymph node biopsy was carried out in patients with melanoma of the following characteristics: Breslow thickness ≥1mm, Breslo…
Robotic Hysterectomy in Severely Obese Patients With Endometrial Cancer: A Multicenter Study
2015
Abstract Study Objective The aim of this study was to evaluate the surgical and oncologic outcomes of robotic hysterectomy with or without or less pelvic and aortic lymphadenectomy in severely obese patients (body mass index [BMI] ≥ 40 kg/m 2 ) with endometrial cancer. Material and Methods Between August 2010 and November 2014, patients with histologically confirmed endometrial cancer and BMI ≥40 kg/m 2 were deemed eligible for the study and underwent RH with or without pelvic and aortic lymphadenectomy. Results Seventy patients were divided into 3 groups according to their BMI: group A, BMI between 40 and 45 kg/m 2 (50 patients); group B, BMI between 45 and 50 kg/m 2 (10 patients); and gro…
Transperitoneal versus extraperitoneal laparoscopic aortic lymph nodal staging for locally advanced cervical cancer: A systematic review and meta-ana…
2021
Abstract Cervical cancer is the fourth most common neoplasm in women. In locally advanced cervical cancers, the international guidelines recommend nodal aortic assessment. Two techniques have been described to perform laparoscopic aortic lymphadenectomy: transperitoneal laparoscopic lymphadenectomy (TLL) and extraperitoneal laparoscopic lymphadenectomy (ELL). This meta-analysis aims to compare the surgical outcomes of TLL and ELL for staging purposes. The systematic review was carried out in agreement with the preferred reporting items for systematic reviews and meta-analyses statement (PRISMA). Two hundred and twenty studies were analyzed, and 19 studies were included in the review (7 for …
Trend of hospitalized cases of oral cancer in Brazil and its relationship with oral health coverage in public health system between 2009 and 2017
2020
Background This study aimed to analyze the trend in the number of hospitalized cases of oral cancer in Brazil, according to the coverage of oral health services in public health system, and also investigate the influence of healthcare and clinical characteristics on the severity of oral cancer cases. Material and Methods This retrospective study considered the period between 2009 and 2017. Data from the Hospital Registry of Cancer from the National Cancer Institute were used, considering the primary locations C00 to C06. Detailed information including sex, age, alcohol and tobacco use, year of first consultation, and the clinical stage of the cases were also collected. The frequency of hosp…
Robot-assisted cervical esophagectomy: first clinical experiences and review of the literature
2020
Summary Pulmonary complications, and especially pneumonia, remain one of the most common complications after esophagectomy for esophageal cancer. These complications are reduced by minimally invasive techniques or by avoiding thoracic access through a transhiatal approach. However, a transhiatal approach does not allow for a full mediastinal lymphadenectomy. A transcervical mediastinal esophagectomy avoids thoracic access, which may contribute to a decrease in pulmonary complications after esophagectomy. In addition, this technique allows for a full mediastinal lymphadenectomy. A number of pioneering studies have been published on this topic. Here, the initial experience is presented as wel…
Molecular anatomy of the neuro-immune connection.
1991
Light microscopic immunohistochemistry was employed to elucidate and compare the presence, distribution, and coexistence of various peptides, neuroendocrine markers and enzymes of the catecholamine pathway in nerves supplying lymphoid tissues in a variety of mammalian species. All lymphoid organs and tissues receive innervation by fibers containing dopamine-beta-hydroxylase and/or tyrosine hydroxylase, neural markers like protein gene product 9.5, synaptophysin and neurofilament and a varied spectrum of peptides. The prominent peptides were tachykinins (substance P, neurokinin A), calcitonin gene-related peptide (CGRP), neuropeptide Y (NPY), and vasoactive intestinal polypeptide/peptide his…
Lymph node evaluation for resected colorectal cancer
2013
SUMMARY The negative impact of regional lymph node metastasis on survival from nonmetastatic colorectal cancers is proportional to the number of nodes harvested. A thorough lymph node examination by the pathologist is essential for accurate staging. Recommendations in the USA and Europe stipulate that a minimum of 12–15 lymph nodes must be examined to accurately predict regional node negativity. The prognostic separation for stage III colorectal cancer obtained by the lymph node ratio is superior to that of the absolute number of positive nodes. The extent of mesenteric resection, pathologic technique, age or tumor location may influence lymph node yield. In the future, biological signific…
