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.

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.

OBJECTIVE: Our study aimed to confirm the expression of the endocannabinoid system in the human epithelial ovarian tumors, assessing the immunohistochemical expression of Cannabinoid Receptor Type 1 and Fatty Acid Amide Hydrolase in benign, borderline and malignant tumors. MATERIALS AND METHODS: Cannabinoid Receptor Type 1 and Fatty Acid Amide Hydrolase immunohistochemical expression was determined in 118 epithelial ovarian tumors sequentially treated during the last decade in our department: 36 benign, 34 borderline and 48 malignant neoplasms. Cannabinoid Receptor type 1 and Fatty Acid Amide Hydrolase expression resulted predominantly weak-moderate in the benign and borderline forms. RESULTS: concerning malignant tumors, Cannabinoid Receptor Type 1 expression resulted predominantly moderate-strong in Type I tumors and negative-weak in Type II tumors. Fatty Acid Amide Hydrolase expression resulted, instead, independent by the tumor types. Furthermore, there was no significant difference in the Cannabinoid Receptor Type 1 and Fatty Acid Amide Hydrolase expression relatively to the tumoral stages. CONCLUSIONS: The present study confirmed a variable expression of the endocannabinoid system in human ovarian tumors. Cannabinoid Receptor Type 1 expression was significantly different in malignant epithelial ovarian tumors according to dualistic model of ovarian carcinogenesis. Thus, in the most aggressive types II ovarian tumors, Cannabinoid Receptor Type 1 expression resulted predominantly negative or weak.

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.

In the era of precision medicine, the identification of several predictive biomarkers and the development of innovative therapies have dramatically increased the request of tests to identify specific targets on cytological or histological samples, revolutionizing the management of the tumoral biomaterials. The Food and Drug Administration (FDA) has recently approved a selective neurotrophic tyrosine receptor kinase (NTRK) inhibitor, larotrectinib. Contemporarily, the development of multi-kinase inhibitors with activity in tumors carrying TRK fusions is ongoing. Chromosomal translocations involving the NTRK1, NTRK2, and NTRK3 genes result in constitutive activation and aberrant expression of TRK kinases in numerous cancer types. In this context, the identification of tumors harboring TRK fusions is crucial. Several methods of detection are currently available. We revise the advantages and disadvantages of different techniques used for identifying TRK alterations, including immunohistochemistry, fluorescence in situ hybridization, reverse transcriptase polymerase chain reaction, and next generation sequencing-based approaches. Finally, we propose a diagnostic algorithm based on histology and the relative frequency of TRK fusions in each specific tumor, considering also the economic feasibility in the clinical practice.

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.

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

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 of20% 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.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.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.

In the treatment of metastatic colorectal cancer (mCRC), there is a need for a treatment option in patients who have received regorafenib (RGR) therapy and progressed, especially in patients fit enough to receive a new therapy. We aimed to compare the role of rechallenge chemotherapy (RCH CTx) with best supportive care (BSC) in mCRC patients after standard CTx and subsequent RGR treatment in terms of survival benefit.Patients with progressive mCRC who received at least one month of subsequent RGR therapy after standard CTx treatments were included in the study. Patients were divided into two groups: receiving RCH CTx or BSC (without antitumoural therapy) after RGR failure. There were 26 patients in the RCH CTx group and 30 patients in the BSC group. The RCH CTx and BSC groups were compared for demographic and clinical features, laboratory parameters, and survival rates.After the RGR failure, the median overall survival (OS) for the RCH CTx (n = 26) and BSC (n = 30) groups were 7.5 (95% CI, 6.3-8.7) months and 1.2 (95% CI, 0.9-1.5) months, respectively (p0.001). The median OS was 7.5 (95% CI, 6.3-8.7) months for the RCH CTx (n = 26) and 1.4 (95% CI, 0.3-2.4) months for the BSC (n = 14) groups when only the patients with an Eastern Cooperative Oncology Group Performance Status (ECOG PS) ≤ 2 at progression with RGR treatment were compared, respectively (p0.001).After the RGR failure, mCRC patients, especially those with a better ECOG-PS (≤ 2) and adequate organ function, should be considered candidates for RCH CTx instead of BSC.

Integrative Medicine Research Group (IMRG) presents a new conference scene about the "Ageing and osteoarticular system for healthy ageing" within a multidisciplinary approach of Integrative Medicine.

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.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).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.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.
