Prognostic impact of extra-nodal extension in thyroid cancer: A meta-analysis
2015
Background and Objectives Lymph node involvement is common in thyroid cancer, but the system of staging does not consider the histological features of lymph node metastases. We conducted a meta-analysis to investigate the prognostic role of extranodal extension (ENE) in thyroid cancer patients. Methods We ran PubMed and SCOPUS searches without language restrictions. Prospective studies reporting data on overall mortality, cancer-specific mortality, or disease recurrence including thyroid cancer patients, in which cases with ENE (ENE+) were compared with those with only intranodal disease (ENE-) were eligible. Data were summarized using risk ratios (RR) for number of deaths/recurrences, and …
Extranodal Extension of Nodal Metastases Is a Poor Prognostic Indicator in Gastric Cancer: a Systematic Review and Meta-analysis.
2016
Introduction: The extranodal extension (ENE) of nodal metastases (the extension of neoplastic cells through the nodal capsule into the perinodal soft tissue) is a histological feature that has been considered a prognostic factor in several cancers, but the role in gastric cancer was not yet investigated. We aimed to investigate the prognostic role of ENE in patients affected by gastric cancer through a systematic review and meta-analysis. Material and Methods: Two independent authors searched major databases until 09/30/2015 to identify studies providing data on gastric cancer patients’ prognostic parameters and comparing patients with ENE (ENE+) vs intra-nodal extension (ENE−). The data we…
Cardiovascular Damage Induced by Anti-BCR-ABL TKIs
2018
Anti-BCR-ABL TKIs (tyrosine kinase inhibitors) are drugs that inhibit BCR ABL tyrosine. They are used especially in the treatment of hematological cancer and gastrointestinal stromal tumors (GIST). Anti-BCR-ABL TKIs include first (imatinib), second (nilotinib, dasatinib, bosutinib) and third-generation drugs (ponatinib). Especially second- and third-generation drugs can cause cardiovascular complications such as arterial thrombosis, myocardial ischemia, peripheral arterial diseases, QTc prolongation, and pulmonary hypertension. Nilotinib and ponatinib can cause thrombotic arterial events with various mechanisms. Particularly dasatinib can cause pulmonary hypertension. Compared to convention…
Tumor budding as a risk factor for nodal metastasis in pT1 colorectal cancers: a meta-analysis
2017
Worldwide, colorectal cancer (CRC) screening programs have significantly increased the detection of submucosal (pT1) adenocarcinoma. Completion surgery may be indicated after endoscopic excision of these potentially metastasizing early cancers. However, the postsurgical prevalence of nodal implants does not exceed 15%, leading to questions concerning the clinical appropriateness of any post–endoscopy surgery. Eastern scientific societies (Japanese Society for Cancer of the Colon-Rectum, in particular) include tumor budding (TB), defined as the presence of isolated single cancer cells or clusters of fewer than 5 cancer cells at the tumor invasive front, among the variables that must be inclu…
The use of neural networks in identifying risk factors for lymph node metastasis and recommending management of t1b esophageal cancer.
2012
The objective of this study was to establish a prediction model of lymph node status in T1b esophageal carcinoma and define the best squamous and adenocarcinoma predictors. The literature lacks a satisfactory level of evidence of T1b esophageal cancer management. We performed an analysis pooling the effects of outcomes of 2098 patients enrolled into 37 retrospective studies using “neural networks” as data mining techniques. The percentages for lymph node, lymphatic (L1), and vascular (V1) invasion in Sm1 esophageal cancers were 24, 46, and 20 per cent, respectively. The same parameters apply to Sm2 with 34, 63, and 38 per cent as opposed to Sm3 with 51, 69, and 47 per cent. The respective …
Risk of lymph node metastasis in submucosal esophageal cancer: a review of surgically resected patients
2011
Endoscopic local procedures are increasingly applied in patients with superficial esophageal cancer as an alternative to radical oncologic resection. The objective of this article is to determine the risk of nodal metastases in submucosal (sm) esophageal cancer, comparing the two predominating histologic tumor types, squamous cell cancer (SCC) and adenocarcinoma (ADC).A query of PubMed, MEDLINE, Embase and Cochrane Library (1980-2009) using predetermined search terms revealed 675 abstracts, of which 485 full-text articles were reviewed. A total of 105 articles met the selection criteria. A review of article references and consultation with experts revealed additional articles for inclusion.…
Temsirolimus in mantle cell lymphoma and other non-Hodgkin lymphoma subtypes.
2009
Temsirolimus, an inhibitor of mammalian target of rapamycin (mTOR), has anti-tumor activity in patients with relapsed or refractory mantle cell lymphoma (MCL) and other mature lymphoid neoplasms. mTOR is an intracellular kinase that controls the mRNA translation of many proteins (eg, cyclin D1) that can act as oncogenes and contribute to lymphomagenesis. Characterized by overexpression of cyclin D1, MCL was identified as a disease that might be susceptible to mTOR inhibition. When single-agent temsirolimus was explored in two phase II studies for treatment of patients with relapsed or refractory MCL, it demonstrated anti-tumor activity, with overall response rates of 38% and 41%. Subsequent…
An international consortium proposal of uniform response criteria for myelodysplastic/myeloproliferative neoplasms (MDS/MPN) in adults
2015
Abstract Myelodysplastic syndromes (MDS) and myeloproliferative neoplasms (MPN) are hematologically diverse stem cell malignancies sharing phenotypic features of both myelodysplastic syndromes and myeloproliferative neoplasms. There are currently no standard treatment recommendations for most adult patients with MDS/MPN. To optimize efforts to improve the management and disease outcomes, it is essential to identify meaningful clinical and biologic end points and standardized response criteria for clinical trials. The dual dysplastic and proliferative features in these stem cell malignancies define their uniqueness and challenges. We propose response assessment guidelines to harmonize future…
Extranodal extension of nodal metastases is a poor prognostic moderator in non-small cell lung cancer: a meta-analysis
2018
Extranodal extension (ENE) of nodal metastasis is defined as the extension of metastatic cells through the nodal capsule into the perinodal tissue. This morphological parameter, recently proposed as an important prognostic factor in different types of malignancy, has not been included in the TNM staging system for non-small cell lung cancer (NSCLC). In this systematic review with meta-analysis, we weighted the prognostic role of ENE in patients with lymph node-positive NSCLC. Two independent authors searched SCOPUS and PubMed through 28 February 2017. Prospective and retrospective studies on NSCLC, comparing patients with presence of ENE (ENE+) ENE+) vs. only intranodal extension (ENE–) and…
Lungenfunktion nach Bestrahlung bei pädiatrisch-onkologischen Patienten
2008
Lung function tests were performed in 22 children and juveniles who had received radiotherapy to the lungs, an average of 9.5 years previously, for tumour (14 with Hodgkin's disease [aged 7-22 years], 4 with malignant non-Hodgkin lymphoma [aged 6-14 years], 3 with Wilms tumour [4-6 years], and one with Ewing's sarcoma [aged 16 years]). All three patients who, as young children, had had radiotherapy to both lungs because of a Wilms tumour with multiple lung metastases had restrictive disorders of lung function. Four of 12 after treatment of Hodgkin's disease and one of two after malignant non-Hodgkin lymphoma and extensive thoracic irradiation developed a restrictive disorder of pulmonary fu…
