FDG PET-CT: Need for Vigilance in Patients Treated with Bleomycin.

Bleomycin-induced interstitial lung disease is not a rare complication of treatment and may prove to be fatal if not suspected early in its course. As FDG PET-CT has become an essential clinical tool for interim and end-of-treatment response assessment in oncology, it is important that radiologists/nuclear medicine specialists be aware of the features of this potentially treatable condition so that treatment can be instigated during an early reversible phase before pulmonary damage has occurred. Herein, we report two cases of bleomycin toxicity featuring different patterns on the treatment-response assessment FDG PET-CT scan.

Adriamycin in combination with dexamethasone and octreotide lacks activity on the treatment of a 4T1 metastatic breast cancer model.

The aim of this study was to evaluate whether the palliative treatment for metastatic disease with dexamethasone (DEX) plus octreotide (OCT) can improve the anticancer effects of the standard treatment with adriamycin (ADR) on a 4T1 metastatic breast cancer (MBC) model. 4T1 cells were first characterized for the expression of the somatostatin receptors 1-5 and were then inoculated onto the femur of BALB/C mice. Investigation protocols used 4T1 cell proliferation and invasion assays, analysis of radiographic images of the bone metastatic lesions, and overall survival of the diseased animals.

Overview on the current status on virtual high-throughput screening and combinatorial chemistry approaches in multi-target anticancer drug discovery; Part II.

Conventional drug design embraces the "one gene, one drug, one disease" philosophy. Nowadays, new generation of anticancer drugs, able to inhibit more than one pathway, is believed to play a major role in contemporary anticancer drug research. In this way, polypharmacology, focusing on multi-target drugs, has emerged as a new paradigm in drug discovery.

One Coin, No Need to Flip: Shared PET Targets in Cancer and Coronary Artery Disease.

Objective: The purposes of this article are to review the common biologic features of cancer and coronary artery disease assessed with PET tracers, focusing on those already used in the clinic and those with translational potential, and to discuss the current value and expected contribution of PET in diagnosis, risk stratification, and treatment monitoring.

Conclusion: PET using a wide variety of radiotracers enhances understanding of pathophysiologic changes shared by cancer and coronary artery disease, helps establish an accurate diagnosis, and aids in prognostic assessment and management decisions. It is likely that with the evolution of therapeutic strategies for blocking the development and progression of both diseases and with the introduction of novel, specific ligands in clinical practice, PET will play an ever stronger role in diagnosis, risk stratification, and monitoring of therapy.

Is it possible to cure myeloma without allogeneic transplantation?

During the last decades, a better understanding of the biology of multiple myeloma (MM) has led to the application of novel treatment strategies for MM patients. The new anti-myeloma regimens produce higher incidence of durable and of better quality responses and they improve overall survival, challenging the dogma of incurable disease, outside the context of allogeneic transplantation. This review presents all these strategies that aim to cure MM, including continuous treatment i.

Utilization of Systemic Chemotherapy in Advanced Urothelial Cancer: A Retrospective Collaborative Study by the Hellenic Genitourinary Cancer Group (HGUCG).

Background: Advanced urothelial cancer (AUCa) is associated with poor long-term survival. Two major concerns are related to nonexposure to cisplatin-based chemotherapy and poor outcome after relapse. Our purpose was to record patterns of practice in AUCa in Greece, focusing on first-line treatment and management of relapsed disease.

Impact of gsp mutations in somatotroph pituitary adenomas on growth hormone response to somatostatin analogs: a meta-analysis.

Objective: Somatic mutations in the GNAS1 gene, which encodes the alpha-subunit of G stimulatory proteins (gsp), are frequently detected in somatotroph pituitary tumors and have been associated to specific clinical and histopathological characteristics. However, the question whether the presence of a somatic gsp mutation affects the response to somatostatin analog treatment remains unresolved.

Design: Following a literature search, we performed a meta-analysis, including 8 eligible studies, in order to estimate the effect of gsp mutation on the percent reduction of growth hormone (GH) levels during an acute octreotide suppression test (OST).

Regioselective chemical and rapid enzymatic synthesis of a novel redox – Antiproliferative molecular hybrid.

Recent science evidenced the interlinkage of oxidative stress and cancer. Due to the inherent complexity of cancer and its accompanying effect of oxidative stress, novel molecules, containing combinatorial functionalities should be targeted. Herein, we synthesized gemcitabine-5'-O-lipoate derived from a regioselective coupling of the chemotherapeutic drug gemcitabine (GEM), a first-line agent for cancer therapy and α-lipoic acid (LA), a potent antioxidant.

Safranal, a Crocus sativus L constituent suppresses the growth of K-562 cells of chronic myelogenous leukemia. In silico and in vitro study.

Crocin, a main constituent of Crocus sativus L (saffron), has been found to inhibit the growth of K-562 human chronic myelogenous leukemia (CML) cells expressing Bcr-Abl protein tyrosine kinase activity. The aim of our study is to investigate the ability of the bioactive saffron's constituents, crocin (CRC) and safranal (SFR), to inhibit the Bcr-Abl protein activity employing an in silico approach, as well as the in vitro effect of these compounds on K-562 growth and gene expression of Bcr-Abl. In silico molecular docking studies revealed that mostly SFR can be attached to Bcr-Abl protein, positioned inside the protein's binding cavity at the same place with the drug used in the treatment of CML, imatinib mesylate (IM).

Association of VEGF-A splice variant mRNA expression with outcome in bevacizumab-treated patients with metastatic breast cancer.

Background: The prognostic utility of vascular endothelial growth factor A (VEGF-A) splice variants in patients with advanced breast cancer treated with bevacizumab has not been studied.

Patients And Methods: A total of 111 patients with metastatic breast cancer treated with weekly docetaxel or ixabepilone without bevacizumab (cohort A) and 100 treated with weekly paclitaxel and bevacizumab (cohort B) were studied. Formalin-fixed tumors were macrodissected for reverse transcription quantitative polymerase chain reaction relative quantification of VEGF-A165, -189, and -206 isoforms spliced at exon 8 proximal splice site (VEGF-Axxxa) and at exon 8 distal splice site (VEGF-Axxxb).

Thyroid cancer after in vitro fertilization: a retrospective, non-consecutive case-series analysis.

Although a firm association between fertility treatment and thyroid cancer has not been established, the widespread use of IVF, as a substantial reservoir of subclinical thyroid cancer disease and evidence suggesting an estrogen-dependent behavior may render thyroid cancer patients after IVF a distinct subpopulation of particular interest. Thus, a retrospective, non-consecutive case-series analysis of patients with history of thyroid cancer after in vitro fertilization was conducted. Twelve female patients with thyroid cancer who had previously undergone IVF treatment were identified within the cohort of thyroid cancer patients followed in our institution.

Anticarcinogenic activity of polyphenolic extracts from grape stems against breast, colon, renal and thyroid cancer cells.

A major part of the wineries' wastes is composed of grape stems which are discarded mainly in open fields and cause environmental problems due mainly to their high polyphenolic content. The grape stem extracts' use as a source of high added value polyphenols presents great interest because this combines a profitable venture with environmental protection close to wine-producing zones. In the present study, at first, the Total Polyphenolic Content (TPC) and the polyphenolic composition of grape stem extracts from four different Greek Vitis vinifera varieties were determined by HPLC methods.

Calcitonin stimulation tests for the early diagnosis and follow-up of patients with C cell disease: a descriptive analysis.

Background/aim: Residual or recurrent medullary thyroid carcinoma (MTC) after thyroidectomy is diagnosed by elevated serum calcitonin (CT) levels. However, in minimal residual MTC or C-cell hyperplasia (CCH), where imaging studies are often negative, basal CT levels are frequently normal and CT stimulation tests are required. We aimed to compare CT stimulation tests with calcium, pentagastrin and their combination in identifying minimal residual MTC and CCH.

Treatment with bortezomib-based regimens improves overall response and predicts for survival in patients with primary or secondary plasma cell leukemia: Analysis of the Greek myeloma study group.

Plasma cell leukemia (PCL) is a rare and aggressive plasma cell disorder, with poor outcome. Bortezomib-based regimens (BBR) are highly effective in myeloma, but there is limited information about their efficacy and safety in PCL. Thus, we retrospectively collected data from 42 consecutive PCL patients (25 with primary PCL-pPCL and 17 with secondary PCL-sPCL) to explore the role of BBR in this entity.

Neo-adjuvant chemotherapy in early stage non-small cell lung cancer.

Lung cancer treatment has evolved during the last decade from the non-specific cytotoxic drugs to targeted therapy. New diagnostic equipment such as the endobronchial ultrasound bronchoscopy and positron emission tomography has enhanced early lung cancer diagnosis. However; we still need additional novel biomarkers to assist the already used diagnostic techniques.

Obesity and thyroid cancer: epidemiologic associations and underlying mechanisms.

The incidence of thyroid cancer has been rising over the past few decades along with a parallel increase in obesity. Observational studies have provided evidence for a potential association between the two. By contrast, clinical data for a link between type 2 diabetes mellitus, a condition strongly associated with obesity, and thyroid cancer are limited and largely not supportive of such an association.
