The influence of tumor blood flow and microenvironmental factors on the efficacy of radiation, drugs and localized hyperthermia.
1997
It is generally accepted that tumor blood flow, microcirculation, oxygen and nutrient supply, tissue pH distribution, and the bioenergetic status-factors which are usually closely linked and which define the so-called metabolic microenvironment--can markedly influence the therapeutic response of malignant tumors to conventional irradiation, chemotherapy, other nonsurgical treatment modalities, and the cell proliferation activity within tumors. Currently available information on the parameters defining the metabolic micromilieu in human tumors is presented in this review. According to these data, significant variations in these relevant factors are likely to occur between different locations…
A Magnetic Resonance Imaging–Based Prediction Model for Prostate Biopsy Risk Stratification
2018
IMPORTANCE: Multiparametric magnetic resonance imaging (MRI) in conjunction with MRI–transrectal ultrasound (TRUS) fusion-guided biopsies have improved the detection of prostate cancer. It is unclear whether MRI itself adds additional value to multivariable prediction models based on clinical parameters. OBJECTIVE: To determine whether an MRI-based prediction model can reduce unnecessary biopsies in patients with suspected prostate cancer. DESIGN, SETTING, AND PARTICIPANTS: Patients underwent MRI, MRI-TRUS fusion-guided biopsy, and 12-core systematic biopsy in 1 session. The development cohort used to derive the prediction model consisted of 400 patients from 1 institution enrolled between …
Reproduction beyond cancer: A message of hope for young women
2006
Abstract Objective. Aggressive chemotherapy and radiotherapy or radical oncological surgery in young women with cancer has greatly enhanced these patients' life expectancy, but these treatments often cause infertility or premature ovarian failure due to a massive destruction of the ovarian reserve. The objective of this review is to discuss the effect of the various cancer treatments on fertility and present the various fertility sparing operations and fertility preservation strategies. Method. An extensive survey of the most up-to-date literature was performed. Results. This review discusses the impact of current cancer treatment on fertility potential and the various surgical and assisted…
The addition of interleukin-2 to cyclophosphamide therapy can facilitate tumor growth of B16 melanoma.
1995
The role of interleukin-2 (IL-2) on tumor growth of B16F10 melanoma cells was assessed in two sets of mice with different immune status: normal (immunocompetent) mice and immunodeficient mice. The two sets of animals were treated with cyclophosphamide (CY) or IL-2 alone or with a combined therapy of CY+IL-2. On days 6 and 10 after tumor cell injection, we evaluated the incidence of hepatic B16 melanoma metastases and the percentage of hepatic volume occupied by metastatic tissue. We observed that the CY alone (300 mg/kg, days 3 and 8 post-tumoral inoculation) significantly reduced tumor growth in all treated mice; however, CY proved more effective in normal recipients than in immunodeficien…
Neural and genetic correlates of antidepressant response to sleep deprivation - A functional magnetic resonance imaging study of moral valence decisi…
2007
Context: Total sleep deprivation combined with light therapy causes rapid amelioration of bipolar depression. A polymorphism in the promoter for the serotonin transporter influences both antidepressant response and the structure and function of specific brain areas. Objective: To determine whether antidepressant therapy or the genotype of the serotonin transporter influence the pattern of neural response to a task targeting the depressive biases in information processing (moral valence decision). Design: Before-and-after trial studying the biologic correlates of response to treatment. Setting: University hospital. Patients: Twenty inpatients with bipolar depression. Intervention: Repeated t…
Hepatitis C-related cirrhosis. Current status.
2016
Chronic hepatitis C virus (HCV) infection affects around 150 million people. It is a leading cause of liver related morbidity and mortality through its predisposition to liver fibrosis, cirrhosis and end-stage liver complications. New treatments based on direct-acting antivirals have opened a new era in the management of HCV cirrhosis. They allow for HCV eradication without substantial side effects in almost all cirrhotic patients, reducing the risk of hepatocellular carcinoma, liver decompensation and mortality. This review provides an update on HCV cirrhosis. The paper focuses on the disease burden and major progresses in the diagnosis, follow-up and treatment of this patient subgroup.
Multisciplinary management of patients with liver metastasis from colorectal cancer
2016
Abstract: Colorectal cancer (CRC) is one of the leading causes of cancer-related death. Surgery, radiotherapy and chemotherapy have been till now the main therapeutic strategies for disease control and improvement of the overall survival. Twenty-five per cent (25%) of CRC patients have clinically detectable liver metastases at the initial diagnosis and approximately 50% develop liver metastases during their disease course. Twenty-thirty per cent (20%-30%) are CRC patients with metastases confined to the liver. Some years ago various studies showed a curative potential for liver metastases resection. For this reason some authors proposed the conversion of unresectable liver metastases to res…
[Hemostatic effectiveness of TachoSil® patches in radiofrequency assisted minor hepatic resection].
2011
Aim. Intra- and postoperative bleeding represents an extremely serious and frequent complication of hepatic surgery. The aim of this study was to evaluate the effectiveness of TachoSil (R) to improve hemostasis in radiofrequency assisted minor hepatic resection. Methods. Between July 2008 and June 2010, 31 patients underwent radiofrequency assisted minor hepatic resection. At the end of the liver resection a sponge of TachoSil (R) was applied on the liver. Results. The mean intraoperative bleeding from the liver was 56.1 mL (range 0-300 mL). No patients received intra- and postoperative blood transfusion. Surgical drains were removed between the first and the sixth-eight postoperative day. …
Novel therapeutic strategies for patients with NSCLC that do not respond to treatment with EGFR inhibitors
2014
Abstract: Introduction: Treatment with epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs) yields tumour responses in non-small cell lung cancer (NSCLC) patients harbouring activating EGFR mutations. However, even in long-lasting responses, resistance to EGFR TKIs invariably occurs. Areas covered: This review examines resistance mechanisms to EGFR TKI treatment, which mainly arise from secondary EGFR mutations. Other resistance-inducing processes include mesenchymal-epithelial transition factor (MET) amplification, epithelial-mesenchymal transformation, phenotypic change from NSCLC to small-cell lung carcinoma, and modifications in parallel signalling pathways. Current…
Emerging drugs for the treatment of vitiligo.
2020
Introduction: Vitiligo is a relatively common autoimmune depigmenting disorder of the skin. There has been a great advance in understanding the pathological basis, which has led to the development and utilization of various new molecules in treating vitiligo. This review aims at a comprehensively describing the treatments available and the emerging treatment aspects and the scope for future developments.Areas covered: This study comprehensively summarizes the current concepts in the pathogenesis of vitiligo with special focus on the cytokine and signaling pathways, which are the targets for newer drugs. JAK kinase signaling pathways and the cytokines involved are the focus of vitiligo treat…
