Pediatric oncologic endosurgery.

2017

Despite increasing popularity of minimal-invasive techniques in the pediatric population, their use in diagnosis and management of pediatric malignancy is still debated. Moreover, there is limited evidence to clarify this controversy due to low incidence of each individual type of pediatric tumor, huge diversity of the disease entity, heterogeneity of surgical technique, and lack of well-designed studies on pediatric oncologic minimal-invasive surgery. However, a rapid development of medical instruments and technologies accelerated the current trend toward less invasive surgery, including oncologic endosurgery. The aim of this article is to review current literatures about the application o…

Prognostic Parameters in Renal Cell Carcinoma - a New Approach(1)

1989

The prognostic potential of the parameters TNM staging, Robson staging, grading, cell type, growth pattern, and patient age was investigated for 431 patients with operated renal cell carcinoma (RCC). In the individual analyses, staging and grading attained the best results, whereby Robson staging proved to be superior to TNM staging by comparison. Morphological parameters had a more modest effect on the prognosis, but this should not be underestimated. A scale of points based on a comparative biometric evaluation of the various parameters was devised. From this scale, three significantly distinct prognostic groups evolved with a correct prognosis of over 80% on the average for an individual…

Surgical robotics for esophageal cancer

2018

We present an update on robotic techniques and their advantages and use in esophageal cancer surgery. Recent work has shown tremendous progress in robotic-assisted minimally invasive esophagectomy (RAMIE) and lymphadenectomy for esophageal cancer, as well as benefits of robotic surgery in high upper esophageal tumors and T4b disease. We discuss the different RAMIE techniques, especially for intrathoracic anastomosis. The ongoing ROBOT trial had demonstrated superiority of robotic esophageal cancer surgery over open esophagectomy. There are various putative technical advantages of RAMIE over minimally invasive esophagectomy, which need to be proven in future trials.

Safety of high doses of somatostatin analogs in well differentiated NENs in elderly

2019

Abstract Background Neuroendocrine neoplasms (NENs) are a group of heterogeneous neoplasms which can be treated with different therapies: in well differentiated (WD) NENs analogs of somatostatin (SSA) can be used considering their proved antineoplastic and antisecretory effects. This is a multicenter study to investigate the safety of high doses (HDD) analogs of somatostatin (SSA) in WD NENs with particular attention for patients over 70 years of age. Methods We collected clinical data from 13 Italian NENs dedicated Units. Patients with WD NENs, in progression on previous treatments, included SSA, and subsequently treated with HDD-SSA, were considered. Results 170 pts were included: 61.76% …

Coexistence of Von Willebrand disease and gastrointestinal stromal tumor (G.I.S.T): Case report of a rare and challenge association

2019

Von Willebrand disease (VWD) is the most common inherited bleeding disorder and is caused by a quantitative (type 1 and 3) or qualitative (type 2) defect of Von Willebrand factor (VWF). Bleeding from the gastrointestinal (GI) tract is not uncommon in VWD and is usually associated with angiodysplasia. We report herein on the management of a patient affected by VWD2B with severe GI bleeding secondary to gastrointestinal stromal tumor (GIST) complicated by deep vein thrombosis (DVT). The current case demonstrated that the hemostatic balance, in RBDs under specific circumstances, can range from a tendency toward a hemorrhagic to normal or prothrombotic state. In these patients, a close collabor…

Medikamentöse Therapie bei Karzinoiden des Gastrointestinaltraktes

2001

Carcinoid tumors are rare and slowly growing neuroendocrine tumors of the foregut, midgut and hindgut. Drug therapy is of special importance in patients with inoperable metastasising disease. This palliative therapy is aimed at reduction of the hormone-dependent symptoms and inhibition of tumor growth. Somatostatin analogues, alpha-interferon and various chemotherapeutic agents are used for this purpose. Drug therapy can be supplemented by surgical and radiological intervention through interdisciplinary cooperation of the surgeon, radiologist, endocrinologist and gastroenterologist.

TH-302 + Gemcitabine (G + T) vs Gemcitabine (G) in Patients with Previously Untreated advanced Pancreatic Cancer (PAC)

2012

ABSTRACT Background TH-302 is a hypoxia targeted prodrug with a hypoxia-triggered 2-nitroimidazole component designed to release the DNA alkylator, bromo-isophosphoramide mustard (Br-IPM), when reduced in severe hypoxia. A randomized Phase 2B study (NCT01144455) was conducted to assess the benefit of G + T to standard dose G as first-line therapy of PAC. Materials and methods An open-label multi-center study of two dose levels of TH-302 (240 mg/m2 or 340 mg/m2) in combination with G versus G alone (randomized 1:1:1). G (1000 mg/m2) and T were administered IV over 30-60 minutes on Days 1, 8 and 15 of a 28-day cycle. Patients on the G could crossover after progression and be randomized to a G…

Transperitoneal vs retroperitoneal minimally invasive partial nephrectomy: comparison of perioperative outcomes and functional follow-up in a large m…

2020

Abstract Background Aim of this study was to evaluate and compare perioperative outcomes of transperitoneal (TP) and retroperitoneal (TR) approaches in a multi-institutional cohort of minimally invasive partial nephrectomy (MI-PN). Material and methods All consecutive patients undergone MI-PN for clinical T1 renal tumors at 26 Italian centers (RECORd2 project) between 01/2013 and 12/2016 were evaluated, collecting the pre-, intra-, and postoperative data. The patients were then stratified according to the surgical approach, TP or RP. A 1:1 propensity score (PS) matching was performed to obtain homogeneous cohorts, considering the age, gender, baseline eGFR, surgical indication, clinical dia…

Coplanar Indirect-Navigated Intraoperative Ultrasound: Matching Un-navigated Probes With Neuronavigation During Neurosurgical Procedures. How We Do I…

2021

BACKGROUND Intraoperative ultrasound (IOUS) is becoming more and more adopted in neurosurgery, since it has been associated to greater extent of resection (EOR) and to gross total resection (GTR) during brain tumor surgery. IOUS main limitations are spatial resolution, width and orientation of the field of view and scan quality, which are operator-dependent. Furthermore, most neurosurgeons are not confident with this technique, which needs a long learning curve in order to identify and interpret anatomic structures. OBJECTIVE To describe an effective procedure to take advantages of both IOUS and neuronavigation in case of lack of a navigated ultrasound system. METHODS We propose a reliable …
