Breath testing as a method for detecting lung cancer
2014
Early diagnosis of lung cancer is important due to high mortality in late stages of the disease. An ideal approach for population screening could be the breath analysis, due to its non-invasiveness, simplicity and cheapness. Using sensitive methods of analysis like gas chromatography/mass spectrometry in exhaled air of cancer patients were discovered some volatile organic compounds - possible candidates for cancer markers. However, these compounds were not specific for cancer cells. At the same time, integrative approaches used to analyze the exhaled breath have demonstrated high sensitivity and specificity of this method for lung cancer diagnosis. Such integrative approaches include detect…
Phase II study of fulvestrant 250mg/month in patients with recurrent or metastatic endometrial cancer: A study of the Arbeitsgemeinschaft Gynäkologis…
2013
Abstract Objectives The aim of this study is to evaluate the activity and toxicity of fulvestrant, a pure estrogen receptor antagonist in patients with advanced or recurrent endometrial cancer, expressing estrogen and/or progesterone receptors (ER/PR). Methods Eligible patients with advanced or recurrent endometrial cancer not amenable to curative surgery and/or radiotherapy were treated with fulvestrant at a dose of 250mg by IM injection every 4weeks for at least 12weeks. Therapy was continued until disease progression, death, intolerable side effects or end of study. Response was assessed in patients with at least one target lesion according to WHO-criteria. Results Thirty-five patients w…
Staging systems of hepatocellular carcinoma: A review of literature
2013
Hepatocellular carcinoma (HCC) is a major health problem with a high incidence and mortality all over the world. Natural history of HCC is severe and extremely variable, and prognostic factors influencing outcomes are incompletely defined. Over time, many staging and scoring systems have been proposed for the classification and prognosis of patients with HCC. Currently, the non-ideal predictive performance of existing prognostic systems is secondary to their inherent limitations, as well as to a non-universal reproducibility and transportability of the results in different populations. New serological and histological markers are still under evaluation with promising results, but they requi…
[Endovesical treatment as an alternative to BCG for intermediate or high-risk NMI bladder cancer].
2012
A shortage of BCG is foreseen till the end of 2013. Which will be the management of intermediate and high-risk NMI-BC if BCG will not be available? In patients harboring high-risk NMI tumors, particularly T1G3 and Tis, the first therapeutic choice is radical cystectomy. Device-assisted therapies, although showing promising results, should be considered only for selected patients. In intermediate risk patients, intravesical chemotherapy remains a legitimate option even if BCG is available. Thus, in a period of BCG shortage, intravesical chemotherapy should be offered, preferably preceded by early instillation, according to the EAU guidelines.
Fludarabine combined with radiotherapy in patients with locally advanced NSCLC lung carcinoma: a phase I study
2011
Abstract Background and purpose Fludarabine is an adenine nucleoside analogue that has significant activity in hematological malignancies and has shown promising activity in combination with radiation in preclinical solid tumor models. We designed a phase I trial exploring concurrent fludarabine and radiotherapy in patients with advanced non-small cell lung cancer (NSCLC) to determine the maximum tolerated dose (MTD) of fludarabine given with concurrent irradiation. Materials and methods Thirteen patients with stage IIIB NSCLC received thoracic irradiation of 60 Gy. Fludarabine was administered during the 5th and 6th week of radiotherapy. Doses started at 10 mg/m2 per day and increased by s…
Are radiological endpoints surrogate outcomes of overall survival in hepatocellular carcinoma treated with transarterial chemoembolization?
2021
Background& Aims: Time to progression (TTP) and progression-free survival (PFS) are commonly used as surrogate endpoints in oncology trials. We aimed to assess the surrogacy relationship of TTP and PFS with overall survival (OS) in studies of transarterial chemoembolization (TACE) for unresectable hepatocellular carcinoma (u-HCC) by innovative methods. Methods: A search of databases for studies of TACE for u-HCC reporting both OS and TTP or PFS was performed. Individual patient data were extracted from TTP/PFS and OS Kaplan-Meier curves of TACE arms. Pooled median TTP and OS were obtained from random-effect model. The surrogate relationships of hazard ratios (HRs) and median TTP for OS …
Treatment sequence of synchronously (liver) metastasized colon cancer
2016
No standards for staging, systemic therapy or the timing of an operation are defined for patients newly diagnosed with synchronous metastases and a primary in the colon. An expert group of radiologists, medical, radiation and surgical oncologists therefore came together to discuss staging and treatment sequence for these patients and came up with a recommendation based on current evidence of potential therapeutic options. The discussion was organized to debate recommendations centred on 5 topics and therefore the position paper is built upon these titles and their subtitles. Editrice Gastroenterologica Italiana S.r.l.
First results for resetting the antitumor immune response by immune corrective surgery in colon cancer.
1998
BACKGROUND: A critical step for cancer recurrence is the failure of the cellular immune response. It is suspected that chronic humoral immune responses against some tumor-associated antigens (TAA) can contribute to that failure. METHODS: In this study, we tested the ability of an immune corrective surgical procedure to prevent recurrences of colon cancer in stages I, II, and III. Radiolabeled anti-TAG antibodies injected intravenously become concentrated on TAG-72 immune complexes presented by follicular dendritic cells, which are responsible for the persistent humoral response against TAG-72 TAA. Using a hand-held gamma probe, we can intraoperatively detect and remove lymph nodes involved …
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…
