Simultaneous Medullary and Papillary Thyroid Carcinomas: Personal Experience Report and Literature Review.

While the frequency of papillary thyroid carcinoma (PTC) has increased in recent decades, both due to improvements in diagnostic procedures and a real, effective percentage increase in cases, the frequency of medullary thyroid carcinoma (MTC), however, has remained almost unchanged, representing 3-5% of thyroid cancer cases. Our experience relates to the observation of cases with the synchronous presence of PTC and MTC, also in chronic autoimmune thyroiditis, and this led us to carry out a brief review of the literature on the subject, with the aim above all of identifying the most correct postoperative therapeutic process.

Acute appendicitis and its treatment: a historical overview.

Purpose: Acute appendicitis (AA) is the leading cause of acute abdomen worldwide, with an incidence of 90-100 cases per 100,000 individuals annually and a lifetime risk of 7-12%. Despite its prevalence, historical accounts of AA are limited, particularly when compared to conditions like haemorrhoids, likely due to the appendix's internal location. This article traces the historical evolution of AA treatment from ancient times to the present, highlighting key contributions.

Comparative Study of NGS Platform Ion Torrent Personal Genome Machine and Therascreen Rotor-Gene Q for the Detection of Somatic Variants in Cancer.

Molecular profiling of a tumor allows the opportunity to design specific therapies which are able to interact only with cancer cells characterized by the accumulation of several genomic aberrations. This study investigates the usefulness of next-generation sequencing (NGS) and mutation-specific analysis methods for the detection of target genes for current therapies in non-small-cell lung cancer (NSCLC), metastatic colorectal cancer (mCRC), and melanoma patients. We focused our attention on EGFR, BRAF, KRAS, and BRAF genes for NSCLC, melanoma, and mCRC samples, respectively.

Clinical and pathological factors predictive of response to neoadjuvant chemotherapy in breast cancer: A single center experience.

Neoadjuvant chemotherapy (NAC) of breast cancer (BC) improves outcomes, especially in patients with locally advanced and inflammatory cancer. Further insight into clinic-pathological factors influencing outcomes is essential to define the optimal therapeutic strategy for each category of patients and to predict the response to the treatment. In total, 117 patients with BC were treated with NAC with or without trastuzumab between 2010 and 2015.

Efficacy and Safety of Cetuximab plus Radiotherapy in Cisplatin-Unfit Elderly Patients with Advanced Squamous Cell Head and Neck Carcinoma: A Retrospective Study.

Introduction: Concurrent platinum-based chemoradiation currently represents the standard treatment for advanced head and neck cancer (HNC), but it induces a significant toxicity, in particular among elderly patients. Elderly and unfit patients have been underrepresented in clinical trials and there is a need for tailored guidelines.

Methods: A retrospective review of clinical data of HNC patients treated at the Operative Oncology Unit of the San Giovanni di Dio Hospital in Frattamaggiore (Naples, Italy) was performed.

Mitochondria as playmakers of apoptosis, autophagy and senescence.

Mitochondria are the key energy-producing organelles and cellular source of reactive species. They are responsible for managing cell life and death by a balanced homeostasis passing through a network of structures, regulated principally via fission and fusion. Herein we discuss about the most advanced findings considering mitochondria as dynamic biophysical systems playing compelling roles in the regulation of energy metabolism in both physiologic and pathologic processes controlling cell death and survival.

Silybin-Induced Apoptosis Occurs in Parallel to the Increase of Ceramides Synthesis and miRNAs Secretion in Human Hepatocarcinoma Cells.

Silybin is a flavonolignan extracted from (milk thistle) with hepatoprotective, antioxidant, and anti-inflammatory activity. Several studies have shown that silybin is highly effective to prevent and treat different types of cancer and that its antitumor mechanisms involve the arrest of the cell cycle and/or apoptosis. An MTT assay was performed to study cell viability, lipid peroxidation, extracellular NO production, and scavenger enzyme activity were studied by Thiobarbituric Acid-Reactive Species (TBARS) assay, NO assay, and MnSOD assay, respectively.

Carcinogenetic mechanisms of endocrine disruptors in female cancers (Review).

Endocrine disruptors (EDs) are pollutants that alter the endocrine system and are involved in carcinogenesis. EDs have multiple and complex levels of action. They can affect the synthesis, release and transport of natural hormones.

Role of perineural invasion as a prognostic factor in laryngeal cancer.

The diffusion of laryngeal cancer cells in the perineural space is a parameter associated with a negative prognosis, high loco-regional recurrence and low disease-free survival rates. The spread of tumor cells on the perineural sheath highlights the histopathological and clinically aggressive behavior of this type of tumor, which may extend proximally or distally in the nerve for >10 cm. Therefore, the surgical resection margin is generally insufficient to treat patients with laryngeal cancer presenting with perineural invasion (PNI) with surgery alone.

Short-term diet and moderate exercise in young overweight men modulate cardiocyte and hepatocarcinoma survival by oxidative stress.

The present study was designed to evaluate the effects of diet lifestyle on extending lifespan and reducing liver cancer risk. Young overweight men (n = 20), without metabolic syndrome, were placed in a 3-week residential program on a low-fat diet and moderate aerobic exercise. In each subject, pre- and postintervention fasting blood were collected for evaluating levels of serum lipids, and oxidative stress markers.

Postoperative hypocalcemia: assessment timing.

180 total thyroidectomy case studies performed by the same operator in the years 2006-2010, all done with sutureless technique (Ligasure precise(®)). The monitoring of patients involved a dose of serum calcium on the 1st, 2nd, 3rd and seventh post-operative, before the ambulatory monitoring of the patient. Treatment of post-operative thyroidectomy also includes the administration from the first day of post-surgery, of 2 g/day of calcium (calcium lactate gluconate 2940 mg, calcium carbonate 300 mg).

Systemic inflammatory status at baseline predicts bevacizumab benefit in advanced non-small cell lung cancer patients.

Bevacizumab is a humanized anti-VEGF monoclonal antibody able to produce clinical benefit in advanced non-squamous non-small-cell lung cancer (NSCLC) patients when combined to chemotherapy. At present, while there is a rising attention to bevacizumab-related adverse events and costs, no clinical or biological markers have been identified and validated for baseline patient selection. Preclinical findings suggest an important role for myeloid-derived inflammatory cells, such as neutrophils and monocytes, in the development of VEGF-independent angiogenesis.

Anaplastic lymphoma kinase: a glimmer of hope in lung cancer treatment?

Anaplastic lymphoma kinase (ALK) rearrangements (ALK-Rs) have been identified in 3-7% of all non-small-cell lung cancers (NSCLCs) and represent an important molecular target for NSCLC treatment. The authors discuss the role of ALK-Rs in the prediction of clinical-pathological features of NSCLCs and the technical problems related to their determination in specimens. The authors also describe the preclinical and clinical results derived from the use of ALK inhibitors.

Sorafenib in elderly patients with advanced hepatocellular carcinoma: a case series.

Objective: The management of hepatocellular carcinoma (HCC) in elderly patients is significantly more complicated than in younger patients because of medical comorbidities, advanced status at diagnosis, reduced liver function and altered drug pharmacokinetics. Our objective was a revision of the charts of unselected elderly patients with HCC being treated with a reduced starting dose of sorafenib.

Methods: Activity, adverse events and quality of life were evaluated during the treatment.

Type I interferons: ancient peptides with still under-discovered anti-cancer properties.

Type I interferons (IFNs) represent a group of cytokines that act through a common receptor composed by two chains (IFNAR-1 and IFNAR-2). Several in vitro and in vivo studies showed a potent antitumor activity induced by these cytokines. IFN-α, the first cytokine to be produced by recombinant DNA technology, has emerged as an important regulator of cancer cell growth and differentiation, affecting cellular communication and signal transduction pathways.

Protracted low dose of oral vinorelbine and temozolomide with whole-brain radiotherapy in the treatment for breast cancer patients with brain metastases.

Purpose: The management of brain metastases (BM) from breast cancer (BC) needs to be improved, and new therapeutic strategies are urgently requested. In this view, we have evaluated the efficacy, tolerability, and safety of concurrent low protracted dose of temozolomide (TMZ), metronomic oral vinorelbine (VNB), and radiotherapy in BC women with previously untreated BM.

Methods: Thirty-six patients with newly diagnosed BM were treated with TMZ orally administered at a dose of 75 mg/m(2) during whole-brain radiotherapy, followed by 4 weeks off-therapy and a subsequent administration of oral 70 mg/m(2) VNB fractionated in days 1, 3, and 5, weekly for three consecutive weeks plus TMZ at 75 mg/m(2) on days 1-21, all every 4 weeks for up to 12 additional cycles.

Immune-modulating effects of the newest cetuximab-based chemoimmunotherapy regimen in advanced colorectal cancer patients.

Cetuximab is a human-murine chimeric monoclonal antibody to the epidermal growth factor receptor, active for advanced colorectal cancer treatment in combination with chemotherapy. Cetuximab mainly acts by inhibiting epidermal growth factor receptor-mediated pathways in cancer cells; however, in the human host, its IgG1 backbone may offer additional antitumor activity that includes FcγRs-mediated antibody-dependent cell cytotoxicity, phagocytosis, cross priming, and tumor-specific T-cell-mediated immune response. These mechanisms are still under active investigation.

Chondroitin sulphate enhances the antitumor activity of gemcitabine and mitomycin-C in bladder cancer cells with different mechanisms.

Non-muscle invasive bladder cancer is the most common type of bladder cancer in Western countries. The glycosaminoglycan (GAG) layer at the bladder surface non-specifically blocks the adherence of bacteria, ions and molecules to the bladder epithelium and bladder cancer cells express CD44 that binds GAG. Currently, there are few options other than cystectomy for the management of non-muscle invasive bladder cancer with intravesical chemotherapy using several drugs such as gemcitabine (GEM) and mitomycin-C (MMC) with poor prophylactic activity.

Molecular targets and oxidative stress biomarkers in hepatocellular carcinoma: an overview.

Hepatocellular carcinoma (HCC) is a complex and heterogeneous tumor with multiple genetic aberrations. Several molecular pathways involved in the regulation of proliferation and cell death are implicated in the hepatocarcinogenesis. The major etiological factors for HCC are both hepatitis B virus (HBV) and hepatitis C virus infection (HCV).

Single nucleotide polymorphisms of ABCC5 and ABCG1 transporter genes correlate to irinotecan-associated gastrointestinal toxicity in colorectal cancer patients: a DMET microarray profiling study.

Recent findings have disclosed the role of UDP-glucuronosyltransferase (UGT) 1A1*28 on the haematological toxicity induced by irinotecan (CPT-11), a drug commonly used in the treatment of metastatic colorectal cancer (mCRC). We investigated the pharmacogenomic profile of irinotecan-induced gastrointestinal (GI) toxicity by the novel drug-metabolizing enzyme and transporter (DMET) microarray genotyping platform. Twenty-six mCRC patients who had undergone to irinotecan-based chemotherapy were enrolled in a case (patients experiencing ≥ grade 3 gastrointestinal, (GI) toxicity) - control (matched patients without GI toxicity) study.

Prognosis of patients with spontaneous rupture of hepatocellular carcinoma in cirrhosis.

The treatment of cirrhotic patients with spontaneous rupture of hepatocellular carcinoma (HCC) is controversial and largely dependent on general conditions of the patients and compensation of the underlying cirrhosis. We retrospectively reviewed clinical, imaging and surgical records of 24 consecutive cirrhotic patients (17 males, 7 females; age range 52-88 years) with hemoperitoneum from spontaneous rupture of HCC observed from June 2004 to January 2010 at our Institution. When indicated, patients were referred to surgery or trans-arterial embolization (TAE).

Dose/dense metronomic chemotherapy with fractioned cisplatin and oral daily etoposide enhances the anti-angiogenic effects of bevacizumab and has strong antitumor activity in advanced non-small-cell-lung cancer patients.

Background: We designed a translational clinical trial to investigate whether a dose/dense chemotherapy regimen is able to enhance in patients with non-small-cell-lung-cancer (NSCLC) the anti-angiogenic effects of bevacizumab, a murine/human monoclonal antibody to the vasculo-endothelial-growth-factor (VEGF). We also evaluated the antitumor activity of this combination.

Results: The combined treatment induced a significant decline in the blood-perfusion of primary tumor (NMR-study); in serum levels of VEGF, angiopoietin-1, thrombospondin-1; and in the number of VEGF-transporting cells.

Adrenal incidentalomas in the laparoscopic era and the role of correct surgical indications: observations from 255 consecutive adrenalectomies in an Italian series.

Background: The purpose of our study was to evaluate the impact of laparoscopic adrenalectomy on patients with incidentalomas. We analyzed the results of a multi-centre trial that was performed to evaluate the effectiveness of imaging (computed tomography and magnetic resonance imaging) to obtain a correct preoperative diagnosis.

Methods: We obtained our data from the results of a questionnaire that was distributed by mail or email in May 2005 to several surgical units operating in the Campania Region, Italy.

Surgical treatment of intrathyroid metastases: preliminary results of a multicentric study.

Background: Intrathyroid metastases (ITM) are rare and usually have a dismal prognosis. The aim of this study was to detect which neoplasms metastasize most often to the thyroid gland, their clinical features and treatment options.

Materials And Methods: Retrospective analysis of clinical files of 17,122 patients submitted to surgery for thyroid disease between 1995 and 2005.

[Locally advanced breast cancer in elderly patients: treatment standardised or tailored to individual needs?].

Breast cancer in elderly patients occurs frequently and is often inadequately managed. Furthermore, for organizational and social reasons, the incidence of locally advanced neoplasms is higher in this age group than in the younger population. The aim of the study was to assess our experience in this specific pathology and review the international literature on this topic.
