Drug Treatment for Chronic Hepatitis C Infection and Cancer Risk

2017

BACKGROUND In patients with chronic hepatitis C infection, a sustained virologic response (SVR) to interferon-based therapy markedly decreases the incidence of hepatocellular carcinoma (HCC) over the long term. This is also true for patients who have hepatic cirrhosis, as well as for those with HCC-with or without cirrhosis-who have undergone resection or ablation with curative intent. Recent publications, however, have reported a higher incidence of HCC among patients in both of these subgroups who were treated with direct antiviral agents (DAA) rather than interferon-based therapy. METHODS A selective search for pertinent literature was carried out in the PubMed database with the search t…

Transarterial Chemoembolization Before Liver Transplantation in 60 Patients With Hepatocellular Carcinoma

2007

Tumor recurrence is a major problem after orthotopic liver transplantation (OLT) in patients with hepatocellular carcinoma (HCC). In 60 patients OLT was performed for HCC after pretreatment by repeated transarterial chemoembolization (TACE). Forty-four recipients exceeded the Milan criteria. Recurrence-free 5-year survival was 65.2% and 5-year freedom from recurrence was 73.2%. During the waiting time, 14 patients experienced minimal change, which did not fulfill the definition of tumor progression according to official oncological criteria. Five-year freedom from recurrence among patients with stable compared with progressive disease was 93.3% versus 28.1%, respectively (P = .0001). A stri…

Expression of Wild-Type and Variant Estrogen Receptor Alpha in Liver Carcinogenesis and Tumor Progression.

2011

Although estrogen receptors (ERs) are expressed in human hepatocellular carcinoma (HCC), several clinical trials have failed to demonstrate the efficacy of antiestrogen treatment in HCC patients. Recently, the identification of several ER splicing variants has enlightened the complex nature of estrogen signaling in peripheral tissues; this may help understanding estrogen role in either nontumoral or malignant nonclassical target organs, including liver. In this work we have investigated mRNA expression of wild-type and splice variants of ERα in nontumoral, cirrhotic, and malignant human liver, as well as in HCC cell lines, using an exon-specific reverse transcription polymerase chain reacti…

Imaging appearance of treated hepatocellular carcinoma

2013

Surgical resection and imaging guided treatments play a crucial role in the management of hepatocellular carcinoma (HCC). Although the primary end point of treatment of HCC is survival, radiological response could be a surrogate end point of survival, and has a key role in HCC decision-making process. However, radiological assessment of HCC treatment efficacy is often controversial. There are few doubts on the evaluation of surgical resection; in fact, all known tumor sites should be removed. However, an unenhancing partial linear peripheral halo, in most cases, surrounding a fluid collection reducing in size during follow-up is demonstrated in successfully resected tumor with bipolar radio…

Sequentielle transarterielle Chemoembolisation (TACE) des hepatozellulären Karzinoms (HCC) - Erfahrungsbericht eines einzelnen Zentrums über 5 Jahre

2007

PURPOSE: To analyze the course of disease of patients treated with sequential TACE and to evaluate the dependent and independent prognostic factors for patient survival using the Cox Proportional Hazard Model. MATERIALS AND METHODS: 94 patients palliatively treated with TACE. Patients were selected if they had been treated at least 3 times. The TACE procedure was carried out at 8-week intervals using a suspension consisting of a fixed dosage of Mitomycin C (10 mg) and 10 ml Lipiodol. Follow-up investigations included contrast-enhanced multislice CT before and after TACE and assessment of the laboratory test results (i. e., blood count, liver enzymes, and coagulation). RESULTS: In 66.7 % of …

Atteinte de la Muscularis Mucosae dans les tumeurs urothéliales T1 de vessie : facteur pronostique de progression après immunothérapie par BCG

2012

OBJECTIVES: To study the prognostic impact of muscularis mucosae (MM) invasion for pT1 bladder cancer treated by transurethral resection (TUR) and adjuvant Bacille Calmette-Guerin (BCG) intravesical immunotherapy. METHODS: Sixty-six patients treated by BCG intravesical instillations were substaged into pT1a and pT1b, regarding Muscularis Mucosae invasion. Tumor grade, associated carcinoma in situ (CIS), multifocality, tumoral size up to 3cm, BCG maintenance were noted. With a mean follow-up of 50.5±38 months, we studied recurrence, progression, overall and specific survival. Cox's model method was used for multivariate analysis. RESULTS: Tumor recurrence was observed in 30±7% and 43±10% (P=…

Unusual giant chromophobe renal cancer totally managed with laparoscopic technique: Report of a case

2020

Highlights • We describe a case report of giant renal cell chromophobe carcinoma totally treated by laparoscopic surgery. • The size of renal lesion represents a critical point in surgical approach because to perform a laparoscopic radical nephrectomy can be challenging even for skilled surgeons in giant renal tumors. • A brief review of literature was performed to identify outcomes and potentially surgical advantages of laparoscopic approach for retroperitoenal liposarcoma. • The possibility of the laparoscopic approach derives from from the preoperative identification of adipose cleavage, from the absence of invasion of major vascular axes, from the absence of distant metastatic lesions.

Urethral recurrence of transitional cell carcinoma in a female patient after cystectomy and orthotopic ileal neobladder.

2000

A 63-year-old woman presented elsewhere with a unifocal pT1, G3 transitional cell carcinoma at the bladder base in 1995. She underwent urethral sparing cystectomy and ileal neobladder. Intraoperative frozen section from the proximal urethra did not demonstrate tumor involvement. Final histological examination revealed pT1, pN2, G3 transitional cell carcinoma. Adjuvant chemotherapy was not given. In 1998 the patient had symptoms of obstructive voiding due to a 3 3 3 cm. solid mass at the neobladder-urethra anastomosis (see figure). After 6 cycles of methotrexate, vinblastine, doxorubicin and cisplatin and a transient tumor size reduction, the patient was referred to us for local tumor progre…

Vaccination with ENO1 DNA Prolongs Survival of Genetically Engineered Mice with Pancreatic Cancer

2013

Background & Aims Pancreatic ductal adenocarcinoma (PDA) is an aggressive tumor, and patients typically present with late-stage disease; rates of 5-year survival after pancreaticoduodenectomy are low. Antibodies against α-enolase (ENO1), a glycolytic enzyme, are detected in more than 60% of patients with PDA, and ENO1-specific T cells inhibit the growth of human pancreatic xenograft tumors in mice. We investigated whether an ENO1 DNA vaccine elicits antitumor immune responses and prolongs survival of mice that spontaneously develop autochthonous, lethal pancreatic carcinomas. Methods We injected and electroporated a plasmid encoding ENO1 (or a control plasmid) into Kras G12D /Cre (KC) mice …
