Proposal of model for personalized early adapted cancer screening in people living with HIV: experience of "Gaetano Martino" Hospital University of Messina

Human immunodeficiency virus (HIV) infection has historically been related to the development of specific cancers, some of which are so closely linked to the infection, such as Kaposi's Sarcoma (KS), that they have earned the name Acquired Immuno-Deficiency Syndrome (AIDS)-defining cancers (ADCs). While the development of antiretroviral therapy (ART) has decreased the incidence of AIDS-defining cancers, the resulting aging of people living with HIV (PLWH) highlighted an increased occurrence of other forms of cancer. At the "Gaetano Martino" hospital in Messina, we developed a multidisciplinary approach by creating a bridge between the Oncology Unit and the Infectious Diseases Unit to carry out screening and a more rapid diagnostic and therapeutic journey for cancers in PLWH. The goal is to improve the diagnosis of various types of cancer by involving other professionals, such as gastroenterologists and gynecologists, to ensure faster access to treatment and, therefore, a greater chance of survival. In addition, our multidisciplinary approach has also included vaccine screening, offered by the "Gaetano Martino" hospital and useful for preventing the development of specific forms of cancer in the entire population and particularly in PLWH.

Integrative multidisciplinary approaches by the Integrative Medicine Research Group (IMRG): a new frontier in cancer setting

This conference addresses the topic of integrative, multidisciplinary approaches to cancer settings according to evidence-based medicine. The multidisciplinary approach of the researchers involved characterizes this new and complex scenario. The Integrative Medicine Research Group (IMRG) has always been committed to the activities and dissemination of CAM in cancer patients, focusing on the safety and efficacy of these approaches. Thus, one of the main goals of IMRG is to demonstrate that CAM can support cancer patients during treatment and improve their quality of life and survival. In addition, IMRG's multidisciplinary network is ever vigilant in assessing the risks of interactions between cancer drugs and nutraceuticals. We hope that the integrative medicine approach can be transferred to the level of all chronic diseases, including oncology.

Lung cancer and COVID-19: problems and perspectives

COVID-19 pandemic generated concerns about the healthcare of patients with cancer, not simply because of the formidable impact of COVID-19 patients in the public healthcare system, but also due to the overlapping pathognomonic signs of many forms of lung cancer with lung injuries associated with COVID-19. This report tries to shed light on the issue. We evaluated the great concern of people suffering from lung cancer and also infected with SARS-CoV-2 by discussing evidence and data from current literature. Lung cancer in Italy has represented more than 1 case/4 (27%) in the latest ten years and nevertheless, even due to the concurrence of many complex interplays between COVID-19 and cancer even at the immune level, a consensus protocol and expert guidelines to diagnose and treat lung cancer upon SARS-CoV-2 infection are yet lacking. New insights and consensus panels should be therefore proposed, even at the simplistic level about if priority must be either given to COVID-19 or to cancer therapy.

New treatment strategies for HIV-positive cancer patients undergoing anticancer medical treatment: update of the literature

The introduction of highly active antiretroviral therapy (ART) has deeply modified the outcome of HIV patients by improving their overall survival and ameliorating their quality of life (QoL). The prolongation of these patients' survival has led to an increased risk of highly diffused non-infectious diseases, e.g., cardiovascular diseases, endocrine disease, neurological diseases, and cancer. The management of antiretroviral therapy and anticancer agents (AC) can be challenging, due to the possible drug-drug interactions (DDI) between AC and ART. For this reason, a multidisciplinary approach is always preferred as demonstrated by the GICAT (Italian Cooperation Group on AIDS and Tumors). This review aims to analyze the current scientific data regarding the possible effects of ART on the management of HIV-positive cancer patients and to evaluate the possible DDIs that must be taken into consideration when co-administrating ART and AC. A collaboration between all the involved professional figures, particularly infectious disease specialists and oncologists, represents the key to the correct managing of these patients in order to guarantee the best oncological outcome possible.

Integrative oncology: evidence-based medicine - The multidisciplinary experience of the Integrative Medicine Research Group (IMRG)

The purpose of this conference was to explain the relationship between the integrative and complementary medicine and cancer disease through evidence-based medicine. The topics covered are numerous and are characterized by the multidisciplinary approach of the researchers involved in this complex scenario. The Integrative Medicine Research Group (IMRG) studies the complementary and integrative approach in cancer patients with the aim to highlight the risk of drug and nutraceutical interactions and, at the same time, improve the quality of life in this particular set of patients. Our auspicious is to have an integrative medicine approach to all chronic diseases, oncological included.

Adapted physical activity for breast cancer patients: shared considerations with two Olympic and world Italian sports champions

Breast cancer is a growing global public health concern. Thanks to the recent treatments progress, the survival rate of BC patients has significantly improved (88% of 5-year survival rate) and the number of cancer survivors has also increased. Notwithstanding these brilliant results, many BC patients have long-term side effects as pain, oedema, limited mobility, cancer related fatigue, etc. as a consequence of surgical, radiotherapy and medical treatments. For example, posture appears to be frequently altered after mastectomy, due to the impairment of the mobility of the arm caused by surgical scars. All these aspects negatively affect the health-related Quality of Life (QoL) of BC patients. Recent several randomized clinical trials have shown benefits of regular and appropriate physical activity (PA) during and after BC treatment, particularly in terms of benefits for health, reducing fatigue, improving strength levels, QoL and physical function. In this context, two types of sports have demonstrated their affinity and efficacy as treatment support during and after treatments for BC patients: fencing and rowing. Here we report considerations shared with two sport champions: the fencing Olympic gold medal Daniele Garozzo and the rowing World Champion Giovanni Ficarra, with the aim to find the adapted PA for BC patients.

Improved Survival and Quality of Life Through an Integrative, Multidisciplinary Oncological Approach: Pathophysiological Analysis of Four Clinical Cancer Cases and Review of the Literature

Objectives: According to the National Cancer Institute, the integrative medicine (IM) approach to medical care combines standard medicine with complementary and alternative medicine practices that have proved safe and effective.

Methods: We describe the clinical cases of four patients with malignant pleural mesothelioma (MPM), diffuse malignant peritoneal mesothelioma (DMPM), intrahepatic cholangiocarcinoma, and breast cancer (BC) who received supportive treatment (ST) according to an IM approach after the failure of standard cancer treatments or the appearance of serious adverse events caused by antiblastic chemotherapy. The critical role of complementary drugs in reducing the side effects of cancer treatments and normalizing the white cell count is especially apparent in the case of the patient with metastatic BC, who experienced prolonged neutropenia.

Results: The IM approach was well-tolerated and had no adverse side effects. It improved the quality of life (QoL) of all patients and in two cases extended overall survival.

Conclusion: The extended clinical and instrumental response to IM of the patients with malignant mesothelioma and the improved health-related QoL and good tolerance of the ST demonstrated in all cases support the value of this approach in patients whose cancer therapies have failed but who show a good performance status. Our data require confirmation in a well-designed prospective clinical trial.

The role of integrative and complementary medicine in the management of breast cancer patients on behalf of the Integrative Medicine Research Group (IMRG)

The aim of this conference was to explain the role of integrative and complementary medicine in breast cancer patients. The topics covered are numerous and their peculiarities are the multidisciplinary characteristics of the researchers involved. The Integrative Medicine Research Group (IMRG) believes in the complementary and integrative approach in cancer patients to improve the quality of life in this particular setting.

Interleukin-1 blocking agents as promising strategy for prevention of anticancer drug-induced cardiotoxicities: possible implications in cancer patients with COVID-19

Cytokines in cardiac tissue plays a key role in progression of cardiometabolic diseases and cardiotoxicity induced by several anticancer drugs. Interleukin-1β is one on the most studied regulator of cancer progression, survival and resistance to anticancer treatments. Recent findings indicate that interleukin1-β exacerbates myocardial damages in cancer patients treated with chemotherapies and immune check-point inhibitors. Interleukin1-β blocking agent canakinumab reduces major adverse cardiovascular events and cardiovascular death in recent cardiovascular trials. We focalized on the main biological functions of interleukin1-β in cancer and cardiovascular diseases, summarizing the main clinical evidence available to date in literature. Especially in the era of SARS-CoV-2 infection, associated to coagulopathies, myocarditis and heart failure, cancer patients have an increased risk of cardiovascular complications compared to general population, therefore, the pharmacological inhibition of interleukin1-β should be discussed and considered.

Radiotherapy in cancer and rheumathoid arthritis patients: cancer treatment or control of articular flares? We can achieve both

OBJECTIVE

The study was aimed to investigate the role of radiotherapy (RT) as a risk factor for reactivation or worsening of symptoms in patients affected by rheumatoid arthritis (RA) PATIENTS AND METHODS: This is a single-center retrospective observational study on RA patients who developed cancer requiring RT during the course of the disease. The control group consisted of RA patients with cancer who did not undergo RT. In both groups, the disease activity was evaluated at baseline and at 6 and 12 months through the DAS28 index. A relapse was defined as an increase of >20% in DAS28. A radiotherapist evaluated total and daily doses and timing of radiation. Acute and late toxicity was defined as events occurring within 90 days from the start and more than 90 days after the completion of RT, respectively.

RESULTS

Seventy-two RA patients (38F/34M; mean age: 70±9 years; mean disease duration: 13±9 years), 29 (40.2%) of whom received radiotherapy (mean age 72.9±9 years), were enrolled. The most frequent malignancies were breast (27.2%), thyroid (9.8%), and skin (7%). Between radio-treated and non-radio-treated patients, no significant differences in RA reactivation (6/29 vs. 17/43; p=0.12) or mean exacerbation time (6.7 ± 4.9 months compared to 6.4 ± 4.1 months; p=0.78) were found. Overall, RT was well tolerated with low rates of both acute and late toxicity.

CONCLUSIONS

In RA patients, RT was well tolerated and not associated with an increased risk of articular flares. Properly designed prospective clinical studies with a larger number of patients should be performed to confirm these data.

Intestinal, intestinal-type and intestine-localized metastatic adenocarcinoma. Immunohistochemical approach to the differential diagnosis

The pathologist is often called to define the origin of tumors through the help of ancillary studies, mainly immunohistochemical stainings. In this setting, the differential diagnosis between intestinal adenocarcinomas, other tumors with intestinal-type morphology, and adenocarcinomas metastatic to the bowel can be particularly difficult. In such cases, an accurate assessment of the disease is required to address the patients to the optimal treatment. Immunohistochemistry offers the use of multiple antibodies: the integrated evaluation of specific stainings can lead to a correct diagnosis. Particularly, the use of cytokeratins, mucins, and β-catenin could be of great help in most cases. In addition, recently, novel specific markers such as SATB2 and AMACR have been introduced, improving the utility of immunohistochemistry in the differential diagnosis of intestinal-type and intestinal adenocarcinomas.

Reasons why COVID-19 survivors should follow dietary World Cancer Research Fund/American Institute for Cancer Research (WCRF/AICR) recommendations: from hyper-inflammation to cardiac dysfunctions

The World Cancer Research Fund and American Institute for Cancer Research (WCRF/AICR) advise cancer survivors to follow their lifestyle recommendations for cancer prevention.  Recent research indicates that a proper diet could exerts beneficial metabolic and immune effects in humans through the involvement of several, not yet properly known, metabolic pathways. Here, we argue that following WCRF/AICR recommendations could be a strategy to prevent cardiovascular outcomes [fulminant myocarditis, heart failure, venous thromboembolism (VTE)] and acute respiratory distress syndrome (ARDS) in patients during follow-up post COVID-19 infection. We discuss the metabolic effects of a WCRF/AICR based diet, highlighting on the involved cardio-metabolic pathways related on NLRP3 inflammasome-cytokines axis aimed to improve prognosis of COVID-19, especially in patients with cancer.

Non-AIDS defining cancers: a comprehensive update on diagnosis and management

The increasing incidence of chronic pathologies and especially non-AIDS defining cancers, such as lung cancer, hepatocellular carcinoma, breast cancer, colorectal cancer, prostate cancer, and Hodgkin's lymphoma after the introduction of combined antiretroviral therapy requires the infectious diseases specialist to know how and when to suspect and diagnose cancer in people living with HIV. The aim of this review is to provide updated studies and information about non-AIDS defining cancers and their management in PLWH sheading a light on possible futures scenarios.

The potential diagnostic and predictive role of anaplastic lymphoma kinase (ALK) gene alterations in melanocytic tumors

OBJECTIVE

Anaplastic lymphoma kinase (ALK) gene has been demonstrated to be rearranged, mutated or amplified in several haematological and solid tumors. Moreover, the use of ALK inhibitors has recently revolutionized the treatment of ALK-rearranged patients affected by non-small cell lung carcinoma. Herein we review the genetic alterations of ALK in melanocytic neoplasms described in literature, focusing on their potential diagnostic and predictive role.

MATERIALS AND METHODS

The Authors reviewed the pertinent literature through research on PubMed server was performed typing the terms "ALK", "Anaplastic lymphoma kinase", "ALKATI", "Melanoma", "Spitz", "Spitzoid".

RESULTS

ALK translocations were demonstrated in melanocytic neoplasms, particularly in acral melanoma and spitzoid tumors. ALKATI was described in primary and metastatic melanoma, indicating its early occurrence in oncogenesis, with varying immunohistochemical expression of the protein.

CONCLUSIONS

The identification of the specific type of ALK mutations could be interesting for planning biologic therapy of melanoma patients. Further studies are needed to evaluate the possibility to introduce an ALK-targeted therapy in patients affected by malignant melanoma.

COVID-19 and radiotherapy: potential new strategies for patients management with hypofractionation and telemedicine

COVID-19 disease is one of the biggest public health challenges in Italy and global healthcare facilities, including radiotherapy departments, faced an unprecedented emergency. Cancer patients are at higher risk of COVID-19 infection because of their immunosuppressive state caused by both tumor itself and anticancer therapy adopted. In this setting, the radiation therapy clinical decision-making process has been partly reconsidered; thus, to reduce treatment duration and minimize infection risk during a pandemic, hypofractionated regimens have been revised. Moreover, telemedicine shows its helpfulness in the radiotherapy field, and patients get the supportive care they need minimizing their access to hospitals. This review aims to point out the importance of hypofractionated RT and telemedicine in cancer patient management in the COVID-19 era.

Pharmacogenomics as a tool to prevent drug-related hospitalization of elderly cardiology-oncology patients receiving chemotherapeutic agents and multiple symptomatic treatments: a pilot study planned for the Italian health system

OBJECTIVE

Current precision medicine approaches offer powerful tools to optimize medication regimens; however, the potential impact of these tools in cancer patients with multiple drug treatments has not fully appreciated yet. Here we describe a planning project scheduled to start in the next six months.

PATIENTS AND METHODS

The overall endpoint of this project is to explore the potential association between the presence of individual genetic profile and severe toxicity rates in so-called "frail" cancer patients, using a nested case-control study design. The pilot study includes the detection of the individual pharmacogenetic profile of 150 (cases), prospect enrolled cancer "frail" patients, and 150 (control) retrospectively paired enrolled individuals. Methods for addressing the primary endpoint include: (a) Evaluation of cost-effectiveness analysis by recording QALY criteria; (b) Data recording by a brief self-administered questionnaire used to evaluate the adherence of a patient's tests and the impact of this genotyping on the patient's adverse drug reactions (ADR); (c) A sample size of paired (for age, gender, education, social status, geriatric syndromes, number of medications and comorbidities) 150 (cases) and 150 (controls); (d) Genotyping method choice by current widely diffuse platforms.

RESULTS

The investigators believe that genotype screening and the management of the overall cost of health care personalized therapy has the potential to reduce the health care costs of the Italian national health system (SSN).

CONCLUSIONS

Finally, the innovative issue of this project is to advocate the creation of a new model of the co-operative team (Physicians, pharmacist, geneticist and lab manager) that join for planning the most appropriated personalized therapy for their patient.

Features of microvessel density (MVD) and angiogenesis inhibitors in therapeutic approach of hepatocellular carcinoma (HCC)

OBJECTIVE

The curative hepatocellular carcinoma (HCC) therapy was traditionally based on surgical or loco-regional ablation approach. However, HCC is a solid tumor characterized by a highest level of vascularization; therefore, angiogenesis inhibitor could play a pivotal role in the pharmacological therapeutic approach. Despite the low number of approved drugs, a wide range of multi-kinase and MET inhibitor is currently being evaluated in phase II and III study. In this review, we described all the drugs that have shown efficacy in recently and ongoing trials. Moreover, the immunotherapy represents a recent challenge in the HCC treatment. The strategy based on the production of multi-epitope, multi-HLA peptide vaccine naturally processed and presented on primary tumor tissues of HCC patients. A further upgrade of cancer vaccine could be represented by the combination of metronomic chemotherapy and checkpoint inhibitors.

Oral human papilloma virus infection: an overview of clinical-laboratory diagnosis and treatment

OBJECTIVE

The aim of this review is to describe the "hot points" of current clinical governance for oral HPV comprising the use of new diagnostic molecular procedures, namely, Pyrosequencing and Next Generation Sequencing.

MATERIALS AND METHODS

The data on oral HPV was collected through two levels of research. First for all, we used the canonical medical search engines, PubMed, and Medline, followed by the study of current commercial tools for HPV diagnosis, particularly within commercial companies involved in the molecular procedures for HPV detecting and genotyping.

RESULTS

Different medical procedures are now described and used throughout the world in HPV diagnosis and treatment. However, the laboratory methods are often validated and used for genital infections, and, in these cases, data are missing in the literature as regards the clinical approach for oral lesions.

CONCLUSIONS

Dental care units are often the front line for a clinical evaluation of a possible HPV lesion in the oral cavity, which means that correct clinical governance could avoid a viral neoplastic progression of this disease with great advantages for the patient. In this case, the problem is due to the difficulty in lesion recognition but also and more especially the absence of correct laboratory diagnosis and subsequent treatment in the clinical course.

SARS-CoV-2 infection: NLRP3 inflammasome as plausible target to prevent cardiopulmonary complications?

NLRP3 (NOD-, LRR- and pyrin domain-containing protein 3) inflammasome has recently become an intriguing target of several chronic and viral diseases. Here, we argue that targeting NLRP3 inflammasome could be a strategy to prevent cardiovascular outcomes [fulminant myocarditis, heart failure, venous thromboembolism (VTE)] and acute respiratory distress syndrome (ARDS) in patients with SARS-CoV-2 infection. We discuss the rationale for NLRP3 targeting in clinical trials as an effective therapeutic strategy aimed to improve prognosis of COVID-19, analyzing the potential of two therapeutic options (tranilast and OLT1177) currently available in clinical practice.

Prognostic and predictive factors in testicular cancer

OBJECTIVE

Testicular cancer is a relatively rare neoplasia, with an incidence of about 1,5% among male malignancies, usually in the third and fourth decade of life. Although several histological variants are known, with some histotypes affecting older patients (e.g., spermatocytic seminoma), there is a clear predominance (90-95%) of germ cell tumors among young adults patients1. Testicular Germ Cell Tumor (TGCT), undoubtedly the seminoma histological variant more than non-seminoma one, is definitely a highly curable disease, with a distinctive sensitivity to cisplatin-based therapy (and for seminomas to radiotherapy) and an outstanding cure rate of nearly 80% even for patients with advanced disease. So far, clinical and pathohistological features supported our efforts to choose the best treatment option for patients suffering from this malignancy, but we don't clearly enough know molecular and pathological features underlying different clinical behaviors, mostly in early-stage disease: by improving this knowledge, we should better "shape" therapeutic or surveillance programs for each patient, also in order to avoid unnecessary, if not harmful, treatments.

Eculizumab treatment in patients with COVID-19: preliminary results from real life ASL Napoli 2 Nord experience

OBJECTIVE

SARS-CoV-2 (Severe Acute Respiratory Syndrome Coronavirus 2)-related pneumonia, referred to as COVID-19 (Coronavirus Disease 19), is a public health emergency as it carries high morbidity, mortality, and has no approved specific pharmacological treatments. In this case series, we aimed to report preliminary data obtained with anti-complement C5 therapy with eculizumab in COVID-19 patients admitted to intensive care unit (ICU) of ASL Napoli 2 Nord.

PATIENTS AND METHODS

This is a case series of patients with a confirmed diagnosis of SARS-CoV2 infection and severe pneumonia or ARDS who were treated with up to 4 infusions of eculizumab as an off-label agent. Patients were also treated with anticoagulant therapy with Enoxaparin 4000 IU/day via subcutaneous injection, antiviral therapy with Lopinavir 800 mg/day + Ritonavir 200 mg/day, hydroxychloroquine 400 mg/day, ceftriaxone 2 g/day IV, vitamine C 6 g/day for 4 days, and were on Non-Invasive Ventilation (NIV).

RESULTS

We treated four COVID-19 patients admitted to the intensive care unit because of severe pneumonia or ARDS. All patients successfully recovered after treatment with eculizumab. Eculizumab induced a drop in inflammatory markers. Mean C Reactive Protein levels dropped from 14.6 mg/dl to 3.5 mg/dl and the mean duration of the disease was 12.8 days.

CONCLUSIONS

Eculizumab has the potential to be a key player in treatment of severe cases of COVID-19. Our results support eculizumab use as an off-label treatment of COVID-19, pending confirmation from the ongoing SOLID-C19 trial.

Oxygen-ozone therapy as support and palliative therapy in 50 cancer patients with fatigue - A short report

OBJECTIVE

Fatigue may be cause by all cancer treatments, maybe because the tissue damage or the build-up of dead cells derived products.

PATIENTS AND METHODS

At the Mede Clinic in Sacile, Pordenone, Italy, from February 2016 to May 2018 we studied 50 patients with cancer and fatigue (15 with breast cancer, 12 with lung cancer, 11 with colon cancer, 5 with renal cancer, 3 with prostate cancer, 2 with melanoma and 2 hepatocellular carcinoma). Patients were treated with Auto Hemotransfusion (GAE) according to the SIOOT (Scientific Society of Oxygen Ozone Therapy) protocols, two times a week for one month and then twice monthly as maintenance therapy.

RESULTS

Nineteen of them were undergoing neoplastic treatment, 10 had already ended the cancer therapy and 21 were in a palliative setting. The Fatigue Severity Scale was used to assess the extent of fatigue in patients, in order to estimate the severity of the symptom with a score from 1 to 7. No side effects were found, and 35 patients (70%) achieved a significant improvement (> 50%) of the symptoms.

CONCLUSIONS

Our preliminary data demonstrate that ozone therapy is a valid supportive therapy for fatigue in cancer patients, both during cancer therapy and in a palliative setting with no significant side effects.

Hepatitis C-related hepatocellular carcinoma: diagnostic and therapeutic management in HIV-patients

The efficacy of the current HIV therapy has led to increased survival and prolongation of the average life expectancy of people living with HIV (PLWH), as well as the emergence of comorbidities and non-AIDS related cancer. Hepatocellular carcinoma (HCC) is the most common primary liver malignancy. Current evidence suggests that HCC is an important cause of morbidity and mortality in HIV infected patients. In fact, HCC prevalence rate is indeed higher with respect to the general population average. In this paper, we review the diagnostic and therapeutic management of Hepatitis C-related hepatocellular carcinoma in HCV-HIV co-infected patients. Several therapeutic options are available depending on several factors as HCC stage, liver functions, comorbidities and they have been divided into three groups: potentially curative, proven effective but not curative, and unproven or ineffective therapy. In HIV-infected patients, surgical options are preferred compared to non-surgical therapies. Further studies, especially multicenter ones, are needed in order to define the most appropriate, evidence-based therapeutic approach to PLWH suffering from HCC. It also appears necessary to develop appropriate care guidelines for PLWH.

Metastatic Angiosarcoma of the Spleen. A Case Report and Treatment Approach

We report a case of a 28-year-old man with angiosarcoma of the spleen and liver metastases. The aim of this paper is to underline the importance of planned splenectomy in these patients even if they have metastatic disease, and to propose an intensive chemotherapy regimen consisting of anthracyclines, ifosfamide and mesna with G-CSF support.

Multimodal oncological approach in patients affected by recurrent hepatocellular carcinoma after liver transplantation

OBJECTIVE

Hepatocellular Carcinoma (HCC) represents the fifth most common malignancy and the third cancer-related cause of death worldwide. Liver transplantation (LT) is an excellent treatment for patients with small HCC associated with cirrhosis. The purpose of this review is to investigate the possible strategies for the treatment of HCC recurrence after LT based on current clinical evidence.

MATERIALS AND METHODS

A systematic literature search was performed independently by two of the authors using PubMed, EMBASE, Scopus and the Cochrane Library Central. The search was limited to studies in humans and to those reported in the English language.

RESULTS

Thanks to the introduction of strict selection criteria, LT for HCC has achieved a survival rate of 85% at five years. However, the recurrence of HCC after transplantation remains a serious problem that affects about 20% of post-transplant cases. While most recurrences occur within the first 2 years, late recurrences have been described. The prognosis of recurrence is poor despite numerous proposals of the therapeutic option. Lower levels of immunosuppressive therapy and use of mammalian targets of rapamycin (mTORs) is a potential preventive strategy to reduce HCC recurrence post-Lt. Surgical resection and locoregional therapies (mainly TACE and RFA) play a very important role and are associated with improved survival. Conversely, multikinase inhibitors such as Sorafenib and their association with mTOR inhibitors play a role in cases of advanced HCC recurrence not suitable for the surgical or ablative approach.

CONCLUSIONS

Treating HCC recurrence is a multidisciplinary workup involving hepatologists, surgeons, oncologists and radiologists in order to offer a patient-tailored therapy.

Rectal/urinary toxicity after hypofractionated vs. conventional radiotherapy in high risk prostate cancer: systematic review and meta analysis

OBJECTIVE

The aim of our report was to review the literature concerning the toxicity of radiation therapy in patients treated for high-risk prostate cancer, and to evaluate the differences in toxicity between conventional fractionation and hypofractionated treatments, in view of different techniques used in high-risk prostate cancer patients.

MATERIALS AND METHODS

PubMed database has been explored for studies concerning acute and late urinary/gastrointestinal toxicity in high-risk prostate cancer patients treated with radiotherapy. Prospective studies, concerning potential relationship between acute/late genitourinary (GU)/gastrointestinal (GI) toxicity and prostate radiotherapy in patients with high-risk prostate cancer, were included in the final analysis. Data collected from single arm, phase II non-randomized and randomized studies have been evaluated to perform odds ratio for toxicity risk. Furthermore, meta-analysis randomized prospective trials were considered suitable because they had recruited high-risk prostate cancer patients who didn't undergo surgery, with available data on ≥ G2 toxicity frequency.

RESULTS

The initial search provided 606 results, but only 35 manuscripts met all eligibility requirements and were included in this report. In order to perform odds ratio we observed a decrease in late gastrointestinal toxicity for patients treated with hypofractionated schemes compared to CV treated ones. Among patients who underwent conventional treatment, SIB seemed to decrease acute genitourinary side effects; SIB-Hypo treated patients suffered less toxicity than patients treated with hypofractionated- sequential boost schemes. Hypo-SIB schemes would seem less toxic in terms of acute gastrointestinal and late genitourinary side effects than CV-SIB. Therefore, our focus shifted to 6 clinical trials evaluating genitourinary and gastrointestinal toxicity in patients who had been randomized to receive conventional fractionation or hypofractionated treatment, in both cases with IMRT technology. Our meta-analysis of these randomized trials involving patients with high-risk prostate cancer showed a statistically significant increase in late genitourinary toxicity for hypo-treated patients; no difference was observed in acute genitourinary/gastrointestinal toxicity, and in late gastrointestinal toxicity.

CONCLUSIONS

Our analysis doesn't want to establish a definitive truth; very few trials assessed only high risk-class patients. Our purpose is to stimulate further randomized prospective trials focusing both on the effectiveness and toxicity profile (toxicity/effectiveness ratio), taking into account the use of different technologies and doses.

Antioxidant diet and genotyping as tools for the prevention of liver disease

It is well-known that 75% of risk factors of chronic liver disease (CLD) are related to nutrition. These circumstances potentially progress towards liver steatosis, fibrosis and hepatocellular carcinoma (HCC). It still represents an enormous problem for the economy of public health worldwide. Furthermore, validated prevention programs could be the solution. Recent knowledge in understanding molecular determinants of energy liver metabolism and new genetic markers offers new insights into the pathogenesis of CLD and HCC. The main rationale of the present issue is to provide a summary of recent insights into the inherited variants regulating lipid metabolism (steatohepatitis) and acquired mutation for early diagnosis of HCC, specifically focusing on the significance of antioxidant agents and genotyping tests as a cost-effectiveness tool for the prevention of liver disease. Several national healthy programs worldwide promote the daily use of antioxidant nutrients either for the prevention and/or as complementary and alternative medicines (CAM). This review could be advising for the planning of a large-scale clinical trial including a combination strategy of antioxidant agents and genotyping tests in patients with high risk of CLD.

Multimodal approach of advanced gastric cancer: based therapeutic algorithm

Gastric cancer (GC) is the third leading cause of cancer death in both sexes worldwide, with the highest estimated mortality rates in Eastern Asia and the lowest in Northern America. However, the availability of modern treatment has improved the survival and the prognosis is often poor due to biological characteristics of the disease. In oncology, we are living in the "Era" of target treatment and, to know biological aspects, prognostic factors and predictive response informations to therapy in GC is mandatory to apply the best strategy of treatment.The purpose of this review, according to the recently published English literature, is to summarize existing data on prognostic aspects and predictive factors to response to therapy in GC and to analyze also others therapeutic approaches (surgery and radiotherapy) in locally, locally advanced and advanced GC. Moreover, the multidisciplinary approach (chemotherapy, surgery and radiotherapy) can improve the prognosis of GC. The purpose of this review, according to the recently published English literature, is to summarize existing data on prognostic aspects and predictive factors to response to therapy in GC and to analyze also others therapeutic approaches (surgery and radiotherapy) in locally, locally advanced and advanced GC. Moreover, the multidisciplinary approach (chemotherapy, surgery and radiotherapy) can improve the prognosis of GC.

Rational selection of predictive pharmacogenomics test for the Fluoropyrimidine/Oxaliplatin based therapy

OBJECTIVE

Both Fluoropyrimidine and Oxaliplatin (FluOx) are the most common anticancer drugs used to treat colorectal, ovarian, and gastrointestinal cancers. Nevertheless, the efficacy of FluOx-based therapy is often compromised by the severe risk of neurotoxicity, cardiotoxicity, and gastrointestinal toxicity. Stratification of patients for their individual response to drugs is a promising approach for cancer treatment and cost-effectiveness. Here we evaluate the most recent findings on the most appropriate gene variants related to the toxicity in patients receiving FluOx chemotherapy.

MATERIALS AND METHODS

A systematic literature search of the MEDLINE, EMBASE, and Cochrane databases was conducted to identify all clinical studies of any association between DPYD and 5-FU correlated to allelic status of 6 validated polymorphisms in five genes Dihydropyrimidine Dehydrogenase (DPYD), Thymidylate Synthase (TYMS), Glutathione S-Transferase (GSTP1), and DNA-repair genes (ERCC2 and XRCC1).

RESULTS

The stratification of the patients into three genotype profiles group, who are most likely responders to FluOx treatments, provide informations about toxicity and/or resistance before starting therapy. Also, early evaluation cost of panel testing proposed is averaged about €100,00 per sample. The evaluation costs of genotyping before starting treatment could be a good cost-effectiveness strategy.

CONCLUSIONS

Based on the individual genomic profile, the oncologists will have new possibilities, based on the individual genetic profile, to make treatment decisions for their patients and to redefine scheduling and dosage of FluOx-based therapy.

Clinical presentation and outcome of non-AIDS defining cancers, in HIV-infected patients in the ART-era: the Italian Cooperative Group on AIDS and tumors activity

The advent of antiretroviral therapy (ART) has markedly extended the survival rates of patients with human immunodeficiency virus (HIV), leading to suppression even though not eradication of HIV. In HIV infected patients, cancer has become a growing problem, representing the first cause of death. A large number of worldwide studies have shown that HIV infection raises the risk of many non-AIDS defining cancers (NADCs), including squamous cell carcinoma of the anus (SCCA), testis cancer, lung cancer, cancer of the colon and rectum (CRC), skin (basal cell skin carcinoma and melanoma), Hodgkin disease (HD) and hepatocellular carcinoma (HCC). Generally in HIV positive patients NADCs are more aggressive and in advanced stage disease than in the general population. In the ART era, however, the outcome of HIV positive patients is more similar as in the general population. Only about lung cancer the outcome seems different between HIV positive and HIV negative patients. The aim of this article is to provide an up-date on NADCs within the activity of the Italian Cooperative Group on AIDS and Tumors (GICAT) to identify clinical prognostic and predicting factors in patients with HIV infection included in the GICAT.

Feasibility of intraperitoneal Trastuzumab treatment in a patient with peritoneal carcinomatosis from gastric cancer

OBJECTIVES

This case report evaluates the feasibility and efficacy of intraperitoneal (IP) trastuzumab administration in gastric cancer (GC) patients with peritoneal carcinomatoses.

METHODS

Peritoneal metastasis is a common sign of advanced tumor stage, tumor progression or disease recurrence in patients with GC. Recently, the role of HER2 overexpression in GC, occurring in about 20% of cases, is correlated with a worse prognosis. We report the case of 61-years old female, admitted to our Hospital after curative surgery for GC with over-expression of HER2. Seven months after the start of first line chemotherapy treatment a pleuro-peritoneal disease progression occurred, documented by cytological exam; according to HER2 status, we decided to treat the patient with IP trastuzumab administration.

RESULTS

Between September and October 2012, the patient (ECOG performance status was 0), underwent to 6 cycles of IP trastuzumab. Trastuzumab was administered weekly at a dose of 150 mg for each cycle after paracentesis. The safety was good, no local complications (e.g. abdominal pain, peritonitis) occurred. The clinical revaluation evidenced a stable peritoneal disease.

CONCLUSIONS

To our knowledge this is the first report on Trastuzumab use to treat IP metastases from GC, with acceptable toxicity and local disease control.

Head and neck cancer survivors patients and late effects related to oncologic treatment: update of literature

Cancer survivorship represents a new challenge in the third Millennium. In Europe the number of cancer survivors was estimated to be 17,8 million in 2008 and this number is growing. Recent improvements in cancer survival are largely due to earlier diagnosis and advancements in treatment. Despite having favorable effects on cancer survival, radiation therapy, surgery treatment and combination chemotherapy regimens can also cause long-term organ damage and functional disabilities. In this paper we review the most important aspects of long-term toxicities in otolaryngology cancer survivors patients.

Evaluation of genotyping methods and the relative cost of pharmacogenomics

Recently, several methods to assess the quality of cost-effectiveness, cost-utility and cost-benefit in the pharmacogenomic field have become available. A relevant example is the National Institute for Health and Clinical Excellence (NICE). NICE forms a diverse clinical Advisory committee, which stimulates Pharma and Academic communities to produce a robust set of data, including the design and data source, for economic models of personalized healthcare. Personalized medicine includes genomic tests of each patients and their disease into their clinical treatments, so as minimize toxicity and maximize benefits. It is well known that Pharmacogenomics (PG) tests, performed before drug treatment, lower overall medical costs and provide higher quality of life and longer life expectancy. In this issue relative costs of genotyping methods and platforms, were evaluated by "manually cured criteria" due to lack of specific guidelines. Finally, with the progress made in this scenario over the next five years, health decision-making may able to accelerating the translation of genetic technologies into routine clinical laboratory.

Lung cancer in HIV positive patients: the GICAT experience

PURPOSE

AIDS incidence and mortality have decreased since the introduction of highly active antiretroviral therapy (HAART) into clinical practice. HIV-related malignancies, namely Kaposi's sarcoma and Non-Hodgkin's lymphoma, have decreased, whereas non-AIDS defining tumors have been increasing. Our aim was to study the impact of HAART on natural history of lung cancer in HIV-positive patients, comparing patients with HIV-lung cancer treated in the pre-HAART era versus the HAART era.

PATIENTS AND METHODS

We collected 68 patients with HIV-lung cancer diagnosed from 1986 to 2003. Pre-HAART era included 34 patients who did not receive HAART, whereas the HAART era included 34 patients diagnosed after January 1997 who received HAART.

RESULTS

At diagnosis Performance Status (PS) was significantly different, patients with PS ≥ 2 were 44% in the pre-HAART era, versus 29% in the post-HAART era, p = 0.02. The 79.4% of patients in the post-HAART era received chemotherapy alone or with radiotherapy versus 47% in the pre-HAART era, p = 0.04. Cancer was the leading cause of death for both groups, with 29 (85.3%) and 21 (61.8%) patients in the pre- and post-HAART settings, respectively. The median overall survival (OS) was 3.8 months for the pre-HAART population vs. 7 months for the post-HAART patients, p = 0.01.

CONCLUSIONS

HIV-lung cancer patients have a longer overall survival in the post-HAART era versus the pre-HAART era, due to a not detrimental effect of chemotherapy and positive effect of HAART. Lung cancer is the leading cause of death, showing that treatment of the cancer is the most important target now to improve their outcome.

Treatment of 741 Italian patients with chronic fatigue syndrome

BACKGROUND

Chronic Fatigue Syndrome (CFS) is a distinctive syndrome characterized by specific symptoms cluster. CFS mostly affects women and often results in severe functional limitation. Its prevalence varies from 0.4 to 2.5% in the general population. In our prior studies on the clinical features of 205 CFS patients we founded immunological and brain abnormalities. In this paper we illustrate our caseload on CFS treatment.

PATIENTS AND METHODS

From January 2000 to December 2005, we evaluated all the patients admitted at the CFS Unit of the Aviano National Cancer Institute, for staging procedures and treatments. Patients not meeting the Fukuda diagnostic criteria were excluded.

RESULTS

250 male and 491 female (median age 35.5 and 39.3 years, respectively) were enrolled and treated for CFS. As expected, CFS resulted from previous infectious disease in all patients. Female patients showed to be more affected by symptoms than male patients. The treatment schedules followed by the patients included nutritional supplements alone, corticosteroids, antidepressant/sedative drugs, and antiviral/immunoglobulin drugs. Antiviral/ immunoglobulin drugs achieved the best response (15.3% positive responses vs. 8.3% negative responses; OR 0.44, CI 0.26-0.74, p = 0.002). The carrying out of 4 or more treatments showed a protective effect (OR 0.46, CI 0.28-0.77, p = 0.003). This finding was confirmed in the multivariate analysis, adjusted by type of drugs (OR 0.49, CI 0.28-0.84, p = 0.009) and number of treatments carried out (OR 0.51, CI 0.30-0.86, p = 0.01); these two variables were independent.

CONCLUSIONS

These findings show that the antiviral/immunoglobulin approach has a longer positive disease free survival in comparison with other approaches. However, CSF still remains a difficult disease to be effectively treated.

Hematopoietic Growth Factor support in the Elderly treated with Chemotherapy

The 60% of tumors affected patients >65years of age and the future previsions are considering an amount of 70% after 2030. Elderly Patients presents multiple comorbidity, polipharmacy, and disability. Geriatric assessment helps physicians to take the best therapeutic decisions. Clinical conditions influence efficacy and tolerability of chemotherapy. Prophylactic use of G-CSF after chemotherapy lowers the rate and length of severe neutropenia , and decreases the episodes of febrile neutropenia. Anemia is a hematologic condition associated with ageing , but is frequently associated to concomitant chronic disease. Stem cells display increasing resistance to erythropoietin in the elderly patients and this is connected with the onset of pro-inflammatory cytokines characteristic of this age . Anemia is a common adverse event in cancer patients receiving chemotherapy. Several of the symptoms associated with anemia, such as fatigue, syncope, palpitations and dyspnea, reduce patient activity and have a profound effect on the quality of life [QOL]. Considering the unfit or frail status of elderly patient the at home use of pegfilgrastim and weekly or three weekly erythropoietin administration could be preferred for this setting of patients that lack of specialized nursing care or facilities. Further studies, considering the several differences in health organizations in vary countries, could be held to state the real impact of the biosimilars in comparison to the long acting originators in the reduction of costs in this group of patients.

Kaposi' s sarcoma in HIV-positive patients: the state of art in the HAART-era

Kaposi's sarcoma (KS) is a multicentric angioproliferative cancer of endothelial origin typically occurring in the context of immunodeficiency, i.e. coinfection with Human Immonodeficiency Virus (HIV) or transplantation. The incidence of KS has dramatically decreased in both US and Europe in the Highly Active Antiretroviral Therapy (HAART) era. However, KS remains the second most frequent tumor in HIV-infected patients worldwide and it has become the most common cancer in Sub-Saharan Africa. In 1994, Yuan Chang et al discovered a novel γ-herpesvirus in biopsy specimens of human KS. Epidemiologic studies showed that KS-associated herpesvirus (KSHV) or human herpesvirus-8 (HHV-8) was the etiological agent associated with all subtypes of KS. KS has a variable clinical course ranging from very indolent forms to a rapidly progressive disease. HAART represents the first treatment step for slowly progressive disease. Chemotherapy (CT) plus HAART is indicated for visceral and/or rapidly progressive disease. The current understanding of KS as a convergence of immune evasion, oncogenesis, inflammation and angiogenesis has prompted investigators to develop target therapy, based on anti-angiogenic agents as well as metalloproteinase and cytokine signaling pathway inhibitors. These drugs may represent effective strategies for patients with AIDS-associated KS, which progress despite chemotherapy and/or HAART. In this review, we focus on the current state of knowledge on KSHV epidemiology, pathogenesis and therapeutic options.
