What Are Young Women Living Conditions after Breast Cancer? Health-Related Quality of Life, Sexual and Fertility Issues, Professional Reinsertion
2020
In recent decades, the living conditions of young breast cancer (BC) survivors have garnered increasing attention. This population-based study aimed to identify the clinical, social and economic determinants of Health-Related Quality of Life (HRQoL), and to describe other living conditions of young long-term BC survivors. Women with non-metastatic BC diagnosed between 2006 and 2015, aged 45 years and younger at the time of diagnosis, were identified through the Breast and Gynecologic Cancer Registry of the Cô
Predictive Factors of Response to Sunitinib in Imatinib-Resistant Gastrointestinal Stromal Tumors (GISTs): A Multi-Institutional Study
2019
Imatinib 400 mg is the standard of care for medical treatment of advanced GISTs. In the majority of cases, however, GISTs eventually develop resistance to imatinib. The optimal second line treatment has not been established yet and imatinib dose escalation (800 mg) or sunitinib represent two feasible options. The objective of this retrospective, multi-institutional, study is to analyze the validity of several parameters as possible predictive factors of response to sunitinib after imatinib failure. We reviewed 128 metastatic GISTs treated with sunitinib between January 2007 to June 2017. Primary tumour site, metastatic site, c-KIT/PDGFR-α mutational status, PET-FDG status and type…
Multiple granular cell tumors with metachronous occurrence in tongue and vulva. Clinicopathological and immunohistochemical study
2014
Granular cell tumor (GCT) usually occurs as a single tumor, although sometimes multiple lesions can occur. In present report we analyze the clinicopathological and immunohistochemical features of a multiple GCT involving the tongue of a 14-year-old girl, with no other abnormalities, with a metachronous occurrence of a second GCT in vulva, after a period of 10 years. Both tumors revealed S-100, vimentin and CD57 positivity. In addition, over expression of calretinin was observed in tumor cells located in the vicinity of pseudoepitheliomatous hyperplasia (PEH) of the tongue. Tumor vasculature situated close to the PEH showed marked CD105 reactivity, data not described so far, suggesting an in…
Selektion von Patienten mit Rektumtumoren zur lokalen Exzision aufgrund der pr�operativen Diagnostik
2004
Ziel unserer Studie war die Erfassung der Genauigkeit der praoperativen Diagnostik (rektal-digitale Untersuchung, Biopsie und transanale Endosonographie) bei durch lokale Exzision behandelten Rektumtumoren. 552 Patienten mit Rektumkarzinom, Adenom, Karzinoiden oder seltenen benignen Tumoren wurden lokal exzidiert. Die Ergebnisse der rektal-digitalen Untersuchung, der Biopsie und der transanalen Endosonographie wurden mit dem postoperativen pathohistologischen Befund verglichen. Der praoperative histologische Nachweis des Karzinoms ist abhangig von der Tumorgrose (52% bei Karzinomen 3 cm; p=0,001) und war korrekt in 56% aller Karzinome. Die transanale Endosonographie (uT0/1) ist sensitiver (…
Testicular tumors in childhood: a national report
1993
The authors report preliminary data of an Italian multicentric, retrospective study of primary testicular tumors (PTT) in childhood involving 20 Italian departments of pediatric surgery. Forty cases of PTT were observed during a 10-year period (1977–1987), with yolk-sac tumors being the most frequent (45%). Most testicular tumors were first perceived as a unilateral testicular mass. Scrotal ultrasonography represents the main diagnostic investigation, together with serum marker levels.
Therapeutische Strategien bei malignen Weichteiltumoren
2001
Einleitung: Ziel einer Weichteiltumor-Registerstudie der Chirurgischen Arbeitsgemeinschaft Onkologie (CAO) der Deutschen Gesellschaft fur Chirurgie war die Erfassung der Behandlungsstrategien bei malignen Weichteiltumoren des Erwachsenen. Methodik: In 19 Monaten wurden Daten von 292 Patienten von 99 chirurgischen Kliniken Deutschlands nach einem speziell entwickelten Dokumentationsbogen prospektiv zur pratherapeutischen Biopsie, Vorbehandlung, definitiven chirurgischen Therapie, zu multimodalen Masnahmen und zum pathohistologischen Befund erhoben. Ergebnisse: 39 % der Tumoren wurden in Universitatskliniken, 36 % in Schwerpunktkrankenhausern und 24 % in Krankenhausern der Grundversorgung beh…
Hypoxia inducible factor-1 alpha expression is increased in infected positive HPV16 DNA oral squamous cell carcinoma and positively associated with H…
2011
Abstract Background There is increasing evidence for the role of High Risk (HR) Human PapillomaVirus (HPV) in the pathogenesis of Oral Squamous Cell Carcinoma (OSCC). The E6 and E7 oncogenes from HR HPVs are responsible for the deregulation of p53 and pRB proteins involved in cell cycle and apoptotic pathways. In cell lines experiments, the HPV E7 protein seems to be able to enhance Hypoxia Inducible Factor-1 alpha (HIF-1α) activity, normally involved in the response to hypoxia and able to enhance angiogenesis. Results We studied tumor specimens from 62 OSCC; a higher prevalence of tumors in TNM stage II and also in pT2 class between OSCC infected positive HPV16 DNA than non-infected ones w…
First-Line Immune Checkpoint Inhibitor-Based Sequential Therapies for Advanced Hepatocellular Carcinoma: Rationale for Future Trials
2021
<b><i>Introduction:</i></b> Atezolizumab (ATEZO) plus bevacizumab (BEVA) represents the new standard of care for the treatment of advanced hepatocellular carcinoma (HCC). However, the choice of the second-line treatment after the failure of immunotherapy-based first-line remains elusive. Taking into account the weaknesses of the available evidence, we developed a simulation model based on available phase III randomized clinical trials (RCTs) to identify optimal risk/benefit sequential strategies. <b><i>Methods:</i></b> A Markov model was built to estimate the overall survival (OS) of sequential first- and second-line systemic treatments. Seque…
Robotic transanal total mesorectal excision: Is the future now?
2021
Total mesorectal excision (TME) is the standard surgical treatment for the curative radical resection of rectal cancers. Minimally invasive TME has been gaining ground favored by the continuous technological advancements. New procedures, such as transanal TME (TaTME), have been introduced to overcome some technical limitations, especially in low rectal tumors, obese patients, and/or narrow pelvis. The earliest TaTME reports showed promising results when compared with the conventional laparoscopic TME. However, recent publications raised concerns regarding the high rates of anastomotic leaks or local recurrences observed in national series. Robotic TaTME (R-TaTME) has been proposed as a nove…
Immunohistochemical detection of EWS and FLI-1 proteinss in Ewing sarcoma and primitive neuroectodermal tumors: comparative analysis with CD99 (MIC-2…
2001
The molecular analysis of the t(11;22) rearrangement involving EWS/FLI-1 genes is likely to be of diagnostic value in Ewing sarcoma (ES) and primitive neuroectodermal tumors (PNET). The objective of the current study was to analyze the immunohistochemical expression of the EWS and FLI-1 proteins in a group of small round-cell tumors (SRCT) to determine their specificity and relevance in their differential diagnosis. Forty-eight cases-10 conventional ES, 4 large-cell ES, 5 PNET, 9 neuroblastomas (NB), 6 undifferentiated synovial sarcomas (SS), 5 rhabdomyosarcomas (RB), 5 non-Hodgkin lymphomas (NHL), 1 round-cell liposarcoma, and 3 mesenchymal chondrosarcomas-were analyzed. Immunocytochemistr…
