Phase III HEAT Study Adding Lyso-Thermosensitive Liposomal Doxorubicin to Radiofrequency Ablation in Patients with Unresectable Hepatocellular Carcinoma Lesions.

Lyso-thermosensitive liposomal doxorubicin (LTLD) consists of doxorubicin contained within a heat-sensitive liposome. When heated to ≥40°C, LTLD locally releases a high concentration of doxorubicin. We aimed to determine whether adding LTLD improves the efficacy of radiofrequency ablation (RFA) for hepatocellular carcinoma (HCC) lesions with a maximum diameter () of 3 to 7 cm.

A new rapid methodological strategy to assess BRCA mutational status.

Hereditary cancers account for approximately 10 % of breast and ovarian cancers. Mutations of the BRCA1 and BRCA2 genes, encoding two proteins involved in DNA repair, underlie most cases of such hereditary cancers. Women with BRCA mutations develop breast cancer in 50-80 % of cases and ovarian cancer in 10-40 % of cases.

Phase I-II trial of gemcitabine-based first-line chemotherapies for small cell lung cancer in elderly patients with performance status 0-2: the G-STEP trial.

Introduction: Treatment of elderly patients with small cell lung cancer (SCLC) is based on scanty evidence.

Methods: Patients with extensive SCLC, age >70 years, and performance status 0-2 were eligible for a study looking for optimal two-drug combination of gemcitabine (Gem) with vinorelbine (Vin), etoposide (Eto), cisplatin (Cis), or carboplatin (Car). Gemcitabine dose was the same (1000 mg/m2, days 1-8) in all combinations.

Anticancer effect of bisphosphonates: new insights from clinical trials and preclinical evidence.

Bisphosphonates (BPs) are cornerstones in the treatment of patients with compromised skeletal integrity (either cancer related or not). However, a major indication for BPs use remains the treatment of patients with advanced cancer metastatic to the bone. Recently, several observations derived from clinical trials, primarily aimed at establishing the impact of BPs on the bone health of cancer patients, suggested a potential role for these agents as direct anti-tumor drugs.

Results: In normal endometrium (proliferative, secretive and atrophic endometrium) strong homogeneous, E-cadherin and α-catenin reactivity was found; 58.

Metabolic syndrome affects breast cancer risk in postmenopausal women: National Cancer Institute of Naples experience.

Postmenopausal women show the highest incidence of breast cancer in the female population and are often affected by metabolic syndrome. Metabolic syndrome (MS)--characterized by central adiposity, insulin resistance, low serum high-density lipoprotein cholesterol (HDL-C), high serum triglyceride and high blood pressure--seems to be strictly correlated to breast carcinogenesis. We enrolled 777 healthy women and women with breast cancer in our nested case-control study to evaluate the association between MS and breast cancer, analyzing anthropometric parameters (weight, height, BMI, waist and hip circumference), blood pressure, serum HDL-C, triglyceride, fasting plasma glucose, insulin, testosterone and uric acid levels and administering a questionnaire about physical activity, food intake, tobacco use, alcohol abuse, personal and familial history of disease.

Oncosuppressor proteins of fragile sites are reduced in cervical cancer.

FHIT and WWOX are tumor suppressor genes that span the common fragile sites FRA3B and FRA16D, respectively. To analyze possible synergisms among these genes in cervical cancer progression, we considered 159 cervical intraepithelial neoplasias, and 58 invasive squamous cell carcinomas of the uterine cervix. All cases were previously selected as high risk HPV.

Adhesion molecules and p16 expression in endocervical adenocarcinoma.

An immunohistochemical (IHC) study has been conducted on 34 cases of untreated endocervical adenocarcinomas collected among three institutions (Ospedale S. Andrea, Rome; Istituto Nazionale Tumori "Fondazione G. Pascale", Naples; and Clinica Malzoni, Avellino).

Effect of age on hemoglobin levels and quality of life following treatment with epoetin alfa in cancer patients.

A subgroup analysis comparing elderly (age > or =70 years; n=95) with younger (age <70 years; n=390) patients was performed on data from a prospective, multicenter, open-label study assessing the effects of once-weekly epoetin alfa 40,000 International Units (IU) for 16-20 weeks on hemoglobin (Hb) levels and quality of life (QoL) in anemic adult patients undergoing chemotherapy for solid tumors. There were significant increases in mean Hb levels at 4, 8, 12, 16-20 weeks in both age groups (p<0.0001), but no significant differences between groups (p=0.

Galectin-3-expression analysis in the surgical selection of follicular thyroid nodules with indeterminate fine-needle aspiration cytology: a prospective multicentre study.

Background: In the USA, about 30 200 well-differentiated thyroid carcinomas were diagnosed in 2007, but the prevalence of thyroid nodules is much higher (about 5% of the adult population). Unfortunately, the preoperative characterisation of follicular thyroid nodules is still a challenge, and many benign lesions, which remain indeterminate after fine-needle aspiration (FNA) cytology are referred to surgery. About 85% of these thyroid nodules are classified as benign at final histology.

Correlation between variation in quality of life and change in hemoglobin level after treatment with epoetin alfa 40,000 IU administered once-weekly.

Introduction: Anemia is frequently associated with cancer due to the disease itself and antineoplastic treatments. This open-label, uncontrolled, multi-center study evaluated the effects of once-weekly (qw) epoetin alfa 40,000 IU on hemoglobin (Hb) levels and quality of life (QoL) in anemic patients receiving chemotherapy for solid tumors.

Materials And Methods: A total of 522 patients with Hb level < or =12 g/dL received epoetin alfa 40,000 IU qw subcutaneously for 9-20 weeks to reach and maintain Hb range of 12-14 g/dL.

Fractionated ionizing radiation exposure induces apoptosis through caspase-3 activation and reactive oxygen species generation.

Background: Radiation therapy (RT) is a well established therapeutic modality for the treatment of solid tumors. In particular, post-operative RT is considered the standard treatment adjuvant to surgery since its ability to prolong median survival of patients with malignant astrocytoma has been shown; nevertheless the ionizing radiation (IR) treatment fails in a considerable number of astrocytoma patients.

Materials And Methods: Using an ADF human astrocytoma cell line the molecular mechanisms involved in the DNA damage induced by fractionated irradiation (FIR) and single IR treatment have been investigated.

Prevalence of acetowhite areas in male partners of women affected by HPV and squamous intra-epithelial lesions (SIL) and their prognostic significance. A multicenter study.

Background: Estimates for the prevalence of cervical HPV infection vary and are only available for a few populations with regard to male partners. Attention has been drawn to the male role in cancer progression from cervical intra-epithelial neoplasia, but most of the male lesions are subclinical and only visible after acetowhite staining. The prognostic significance of acetowhite areas, of male partners of women affected by HPV and preneoplastic lesions, was evaluated.

Follow-up of high-grade squamous intra-epithelial lesions (H-SIls) in human immunodeficiency virus (HIV)-positive and human papillomavirus (HPV)-positive women. analysis of risk factors.

Background: Human immunodeficiency virus (HIV)-positive women are at high risk of co-infection from human papillomavirus (HPV) and of developing squamous intraepithelial lesions of the cervix.

Materials And Methods: From April 1997 to March 1999, 86 women, affected by high-grade squamous intra-epithelial lesions (H-SILs), were enrolled: 41 were HIV+ (CD4+ count >500/ml) and 45 were HIV-. The diagnosis of high-grade squamous intra-epithelial lesion (H-SIL) was established for each patient by Pap test, colposcopy and guided biopsy.

Bisphosphonates and oral cavity avascular bone necrosis: a review of twelve cases.

Background: Intravenous bisphosphonates are the current standard of care for the treatment of hypercalcemia of malignancy and for the prevention of skeletal complications associated with bone metastases. Recently, retrospective case studies have reported an association between long-term bisphosphonate therapy and osteonecrosis of the jaws.

Patients And Methods: The data for twelve patients, referred to either an oral and maxillofacial surgeon or to an oral medicine specialist for the management of clinically apparent chronic oral osteonecrosis of unknown etiology, were reviewed.

Cytological value of sputum in workers daily exposed to air pollution.

In this study, quantitative modifications of dust cells, siderocytes, Curschmann's spirals and asbestos bodies and qualitative modifications (cellular changes and inflammatory infiltrate) in the sputum of 164 traffic police officers and 218 railway workers, occupationally exposed to environmental pollution, and the sputum of 119 inhabitants of a rural area, were evaluated. The results were correlated with time of exposure and smoking habits. Seventy-three (45%) traffic police officers (TPO), 76 (35%) railway workers (RW) and 29 (24%) of the rural population (RP) were smokers.

PRb2/p130, p107 and p53 expression in precancerous lesions and squamous cell carcinoma of the uterine cervix.

The aim of this study was to investigate pRb2/p130, p107 and p53 expressions in precancerous lesions and squamous cell carcinoma (SCC) of the uterine cervix. We evaluated Human Papillomavirus (HPV) testing and typing and pRb2/p130, p107 and p53 expressions (antibody D07) of 48 patients showing low-grade cervical intraepithelial neoplasia (LCIN, 18 cases), high-grade CIN (HCIN, 13 cases) and SCC (17 cases). Paraffin-embedded tissue sections were analyzed for the study.

Clinical experience with bevacizumab in colorectal cancer.

Angiogenesis, the process of generating new capillary blood vessels, is a fundamental requirement for normal physiological processes including embryogenesis, reproductive function and wound healing. Angiogenesis is also implicated in various pathological conditions including age-related retinal macular degeneration, diabetic retinopathy, rheumatoid arthritis, psoriasis and cancer growth and metastasis. Vascular endothelial growth factor (VEGF) is one of the best characterized of the pro-angiogenic growth factors, and multiple strategies have been developed to inhibit this pathway.

Nail disorders in a woman treated with ixabepilone for metastatic breast cancer.

Ixabepilone (Ix) (BMS-247550) is a potent member of a new class of microtubule-stabilizing cytotoxic agents known as epothilones. In pre-clinical studies, Ix has shown anticancer activity against several cancer types, including paclitaxel-resistant models, both in vitro and in vivo. The major toxicities associated with Ix are myelosuppression, sensory neuropathy and neutropenia.

Gastric mucosa alterations in first-degree relatives of gastric cancer patients.

Background: First-degree relatives of gastric cancer patients have an increased risk of developing such neoplasia, and several alterations in gastric mucosa of these subjects have been described. On the other hand, both gastric cell hyperproliferation and abnormalities of adhesion molecules have been involved in gastric carcinogenesis. We studied gastric mucosa alterations in first-degree relatives of gastric cancer patients.

Accuracy rates of US-guided vacuum-assisted breast biopsy.

A prospective study designed to measure the accuracy of mammography (MRx), ultrasound (US), fine-needle aspiration cytology (FNAC) and one of the most recently introduced techniques, vacuum biopsy (VB), in the diagnosis of breast cancer is reported. A sample of 146 breast lesions on 135 patients were examined. The design of the study made it possible to compare MRx, US, FNAC and VB directly, because it excluded several confounding variables.

Relationship between beta-catenin expression and epithelial cell proliferation in gastric mucosa with intestinal metaplasia.

Aim: To investigate beta-catenin expression in patients with intestinal metaplasia, and to look for a possible relationship between beta-catenin expression and either epithelial proliferation values or Helicobacter pylori (H pylori) infection.

Methods: Twenty patients with complete type intestinal metaplasia were studied. beta-Catenin expression and epithelial cell proliferation in antral mucosa were assessed using an immunohistochemical analysis.

Myc down-regulation sensitizes melanoma cells to radiotherapy by inhibiting MLH1 and MSH2 mismatch repair proteins.

Purpose: Melanoma patients have a very poor prognosis with a response rate of <1% due to advanced diagnosis. This type of tumor is particularly resistant to conventional chemotherapy and radiotherapy, and the surgery remains the principal treatment for patients with localized melanoma. For this reason, there is particular interest in the melanoma biological therapy.
