RESUMO

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.

RESUMO

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.

RESUMO

INTRODUCTION: Skin reactions and cardiotoxicity are one of the most common side effects of doxorubicin in cancer patients. The main mechanisms based on the etiopathogenesis of these reactions are mediated by the overproduction of proinflammatory cytokines, metalloproteases, and the disruption of mitochondrial homeostasis. Ozone therapy demonstrated anti-inflammatory effects in several preclinical and clinical studies. The aim of this research is based on the evaluation of cardioprotective and dermatoprotective effects of ozone during incubation with doxorubicin, giving preliminary evidences for further studies in the field of cardio-oncology. METHODS: Human skin fibroblast cells and human fetal cardiomyocytes were exposed to doxorubicin at subclinical concentration (100 nM) alone or combined with ozone concentrated from 10 up to 50 µg/mL. Cell viability and multiple anti-inflammatory studies were performed in both cell lines, with particular attention on the quantification of interleukins, leukotriene B4, NF-κB, and Nrf2 expressions during treatments. RESULTS: Ozone decreased significantly the cytotoxicity of doxorubicin in skin fibroblasts and cardiomyocytes after 24 h of incubation. The best cytoprotective effect of ozone was reached to 30 µg/mL with a plateau phase at higher concentration. Ozone also demonstrated anti-inflammatory effects decreasing significantly the interleukins and proinflammatory mediators in both cells. CONCLUSION: Ozone exerts cardioprotective and dermatoprotective effects during incubation with doxorubicin, and the involved mechanisms are mediated by its anti-inflammatory effects. The overall picture described herein is a pilot study for preclinical studies in oncology.

RESUMO

BACKGROUND: The immunotherapy has revolutionized the world of oncology in the last decades with considerable advantages in terms of overall survival in cancer patients. The association of Pembrolizumab and Trastuzumab was recently proposed in clinical trials for the treatment of Trastuzumab-resistant advanced HER2-positive breast cancer. Although immunotherapies are frequently associated with a wide spectrum of immune-related adverse events, the cardiac toxicity has not been properly studied. PURPOSE: We studied, for the first time, the putative cardiotoxic and pro-inflammatory effects of Pembrolizumab associated to Trastuzumab. METHODS: Cell viability, intracellular calcium quantification and pro-inflammatory studies (analyses of the production of Interleukin 1ß, 6 and 8, the expression of NF-kB and Leukotriene B4) were performed in human fetal cardiomyocytes. Preclinical studies were also performed in C57BL6 mice by analyzing fibrosis and inflammation in heart tissues. RESULTS: The combination of Pembrolizumab and Trastuzumab leads to an increase of the intracellular calcium overload (of 3 times compared to untreated cells) and to a reduction of the cardiomyocytes viability (of 65 and 20-25%, compared to untreated and Pembrolizumab or Trastuzumab treated cells, respectively) indicating cardiotoxic effects. Notably, combination therapy increases the inflammation of cardiomyocytes by enhancing the expression of NF-kB and Interleukins. Moreover, in preclinical models, the association of Pembrolizumab and Trastuzumab increases the Interleukins expression of 40-50% compared to the single treatments; the expression of NF-kB and Leukotriene B4 was also increased. CONCLUSION: Pembrolizumab associated to Trastuzumab leads to strong cardiac pro-inflammatory effects mediated by overexpression of NF-kB and Leukotriene B4 related pathways.

RESUMO

Endocrine disrupters are strictly associated to cancer and several cardiovascular risk factors. Bisphenol A (BPA) is an endocrine disrupter commonly used in the manufacturing of plastics based on polycarbonate, polyvinyl chloride and resins. Our study aims to investigate whether BPA may cause pro-oxidative and pro-inflammatory effects on cardiomyoblasts, thus exacerbating the Doxorubicin (DOXO)-induced cardiotoxicity phenomena. We tested the metabolic effects of BPA at low doses analyzing its affections on the intracellular calcium uptake, oxidative stress, lipid peroxidation and production of nitric oxide and interleukins. Co-incubation of BPA and DOXO significantly reduced the cardiomyoblast viability, compared to only DOXO exposure cells. The mechanisms underlying these effects are based on the stimulation of the intracellular calcium accumulation and lipid peroxidation. Notably, BPA increase the production of pro-inflammatory interleukins involved in cardiovascular diseases as well as in DOXO-Induced cardiotoxicity phenomena. This study provides a rationale for translational studies in the field of cardio-oncology.

RESUMO

Neuroendocrine Neoplasms (NEN) are a group of heterogeneous malignancies derived from neuroendocrine cell compartment, with different roles in both endocrine and nervous system. Most NETs have gastroentero-pancreatic (GEP) origin, arising in the foregut, midgut, or hindgut. The 2010 WHO classification divides GEP-NETs into two main subgroups, neuroendocrine tumors (NET) and neuroendocrine carcinomas (NEC), according with Ki-67 levels. NET are tumors with low (<20 %) Ki-67 value, and NECs, including small cell lung carcinomas and Merkel Cell carcinomas, are all NETs with high Ki-67 levels (>20 %-G3). Poorly differentiated neuroendocrine carcinomas (NEC) are usually treated with cisplatin-based chemotherapy regimens. Here we present a case of a patient with pancreatic NEC progressing after cisplatin and etoposide, treated with temozolomide as palliative, second line treatment. According with the poor Performance Status (PS = 2) and to reduce the toxicity of the treatment was chosen an intermittent dosing regimen of metronomic temozolomide (75 mg/m(2)/day-one-week-on/on-week-off). MGMT resulted methylated. On July 2014 the patient started the treatment. On August 2014 the patient obtained a significant clinical benefit (PS = 0) and the total body CT scan performed on October 2014 showed a RECIST partial response on all the sites of disease. No drug-related side effects were reported by the patient. After 18 months of therapy the treatment continues without significant toxicity, and with further remission of the metastases. Treatment with metronomic "one-week-on/on-week-off" Temozolomide can be considered a good treatment option in patients with poor performance status, affected by pNEC with MGMT methylation.

RESUMO

BACKGROUND: Preoperative treatment of resectable liver metastases from colorectal cancer (CRC) is a matter of debate. The aim of this study was to assess the feasibility and activity of bevacizumab plus FOLFIRI in this setting. METHODS: Patients aged 18-75 years, PS 0-1, with resectable liver-confined metastases from CRC were eligible. They received bevacizumab 5 mg kg(-1) followed by irinotecan 180 mg m(-)(2), leucovorin 200 mg m(-)(2), 5-fluorouracil 400 mg m(-)(2) bolus and 5-fluorouracil 2400 mg m(-)(2) 46-h infusion, biweekly, for 7 cycles. Bevacizumab was stopped at cycle 6. A single-stage, single-arm phase 2 study design was applied with 1-year progression-free rate as the primary end point, and 39 patients required. RESULTS: From October 2007 to December 2009, 39 patients were enrolled in a single institution. Objective response rate was 66.7% (95% exact CI: 49.8-80.9). Of these, 37 patients (94.9%) underwent surgery, with a R0 rate of 84.6%. Five patients had a pathological complete remission (14%). Out of 37 patients, 16 (43.2%) had at least one surgical complication (most frequently biloma). At 1 year of follow-up, 24 patients were alive and free from disease progression (61.6%, 95% CI: 44.6-76.6). Median PFS and OS were 14 (95% CI: 11-24) and 38 (95% CI: 28-NA) months, respectively. CONCLUSION: Preoperative treatment of patients with resectable liver metastases from CRC with bevacizumab plus FOLFIRI is feasible, but further studies are needed to define its clinical relevance.

RESUMO

This paper focused on the biodistribution of the cross-linked hyaluronic acid (HA-NPs) sub-micron particles in tumor-bearing mice. Solvent-non solvent method followed glutaraldehyde cross-linking utilized for the fabrication of HA-NPs. Size measurement and morphological analysis were performed by dynamic light scattering and electron microscopy, respectively and the size found to be in the range of 200-400 nm. In vitro viability in LNCaP cell line was assessed by water soluble tetrazolium assay after 24 h of exposure to sub-micron particles and no toxicity was found to higher concentration of 3 mg/mL. Internalization of particles in prostate cancer cell LNCaP were studied by confocal microscopy with FITC labeled submicron particles and involvement of hyaluronan receptor mediated uptake/endocytosis was confirmed by competitive assay. Biodistribution studies were performed in xenograft prostate cancer mice model with fluorophore labeled particles and monitored in tumoral parenchyma with strong fluorescence, meanwhile very less signal in liver, kidney and spleen while no fluorescence found in lung after 24 h of systemic administration; that shown ability of this HA based system to recognize cancer tissue. These result fetched that hyaluronic acid based system is selective for tumoral site and can be utilized to deliver bioactives in specific (targeting) and controlled (temporal) manner to cancerous tissue.

RESUMO

The standard treatment of CRC patients with hepatic metastases is systemic chemotherapy; however, 5-year survival is disappointingly poor despite recent advances. On the other hand, in patients who undergo immediate radical surgical resection of hepatic metastases, 5-year survival reaches 30-40%. Unfortunately, only 15-20% of patients with hepatic metastases are initially eligible for a radical surgical approach. The majority of patients undergoing liver resection relapse after surgery. For this reason, new onco-surgery approaches have been investigated in recent years and the addition of biological agents to chemotherapy, such as bevacizumab and cetuximab, and the improvements of surgical techniques have opened a new scenario in the management of colorectal liver metastases. Recently, the EORTC trial has demonstrated that perioperative chemotherapy (Folfox regimen) is feasible and improves progression-free survival in patients with resectable liver metastases. Chemotherapy and surgery can finally collaborate. In the unresectable setting, the association of chemotherapy with bevacizumab and cetuximab is particularly promising in improving resectability rate. In particular, K-RAS is a molecular response predictive factor that could be particularly useful in selecting the best treatment option in patients with unresectable liver disease.

RESUMO

Current management of bone metastases involves a multimodal approach. Aminobisphosphonates (BPs) are a valid weapon in the treatment of skeletal localization of tumour disease. Patients with bone metastases from breast and lung cancer were enrolled in order to evaluate the impact of the addition of bisphosphonates therapy to standard treatments in terms of (i) pain control, (ii) quality of life (QoL) and (iii) toxicity and to evaluate (iv) any relations between clinical activity and the occurrence of SREs. A total of 60 patients were included in the study. Median age was 76 years (range 40-83). The majority of patients were treated with chemotherapy or hormonal therapy. All patients received zoledronic acid (ZOL) (4 mg) every 3-4 weeks for at least 3 cycles. No significant improvement in Performance Status of patients after 12 cycles of ZOL (p = 0.1672) was recorded. A statistically significant early and long-lasting amelioration of both pain, narcotic scores and QoL was found. Twenty-one patients (48%) experienced at least one SRE during the study. The most common SRE was radiation to bone (30% of patients). An inverse correlation between bone tumour response and SREs was also found (p = 0.019). ZOL addition induces a clinical benefit and improves QoL of patients with bone metastases. Moreover, the occurrence of bone clinical response is related to a reduced risk of SREs.

RESUMO

The methotrexate, vinblastine, doxorubicin, cisplatin (M-VAC) regimen has been considered as standard treatment of metastatic bladder carcinoma till recent years. The superiority of M-VAC both to cisplatin alone and to another cisplatin combination regimen has been demonstrated in randomized studies. During the last years, the use of gemcitabine in metastatic bladder carcinoma has considerably increased, mainly in combination with cisplatin (CG). A phase III trial comparing M-VAC and CG demonstrated similar activity and less toxicity for CG, which has now become the new standard of care for patients with metastatic bladder carcinoma. The substitution of cisplatin with carboplatin, the combination of platinum and taxanes, and the addition of a third drug to basal CG combination represent possible ways to improve outcome. Among the novel cytotoxic compounds, pemetrexed has raised interest, since a phase II second-line study showed a 28% response rate with a manageable toxicity profile. Vinflunine is a novel antitubulin agent with a relevant clinical activity in pretreated metastatic bladder carcinoma (18% response rate, 6.6 months median survival). Novel biologic compounds (in particular drugs targeting epidermal growth factor receptor) are being tested in metastatic bladder carcinoma also and much effort is being pursued in understanding the determinants of tumor response. Crucial mutations to which the tumor becomes addicted have to be discovered so that more effective and specific drugs or combinations can be delivered.

RESUMO

Epidemiologic analysis reveals that mortality rates from ovarian cancer are continuously decreasing due to the improvement of surgery and chemotherapy. However, overall, the prognosis of ovarian cancer patients is still unsatisfactory considering that only 30% of the patients are alive after 5 years. In fact, although surgery and first-line systemic chemotherapy induce complete and partial response in up to 80% of patients, with about a 25% pathological complete remission rate, recurrences occur in the majority of patients. Most of these patients are subject to repetitive treatment cycles that, although palliative in nature, are also able to prolong survival. Important results have been obtained, in particular in platinum sensitive recurrent disease where a platinum base chemotherapy is able to prolong progression-free survival and overall survival. Overall, our armamentarium for the treatment of progressive or recurrent ovarian cancer is significantly richer than in the past, and in many patients it is possible to achieve the objective to reach a chronic history of the disease.

RESUMO

Hormonal therapy is the preferred systemic treatment for recurrent or metastatic, post-menopausal hormone-receptor-positive breast cancer. Previous studies have shown that there is no cross-resistance between exemestane and reversible aromatase inhibitors. Exposure to hormonal therapy does not hamper later response to chemotherapy. Patients with locally advanced or metastatic, hormonal receptor positive or unknown, breast cancer were treated with oral anastrozole, until disease progression, followed by oral exemestane until new evidence of disease progression. The primary end point of the study was clinical benefit, defined as the sum of complete responses (CR), partial responses (PR) and > 24 weeks stable disease (SD). In all, 100 patients were enrolled in the study. Anastrozole produced eight CR and 19 PR for an overall response rate of 27% (95% CI: 18.6-36.8%). An additional 46 patients had long-term (> 24 weeks) SD for an overall clinical benefit of 73% (95% CI: 63.2-81.4). Median time to progression (TTP) was 11 months (95% CI: 10-12). A total of 50 patients were evaluated for the second-line treatment: exemestane produced one CR and three PR; 25 patients had SD which lasted > or = 6 months in 18 patients. Median TTP was 5 months. Toxicity of treatment was low. Our study confirms that treatment with sequential hormonal agents can extend the period of time during which endocrine therapy can be used, thereby deferring the decision to use chemotherapy.

RESUMO

AIM: To verify the rationale of a pelvic stop-flow technique for the perfusion of high-doses of mitomycin C and anthacyclines in patients with inoperable, recurrent pelvic cancer. METHODS: The stop-flow technique was realized by using percutaneous double-balloon arterial-venous catheters that selectively isolate the pelvic vascular section and a perfusion provided by an extracorporeal pump for 20 min. Ten patients (pts) with unresectable pelvic recurrence from colon-rectal cancer were treated with a combination of Mitomycin C (MMC, 20 mg/sqm) plus doxorubicin (DOXO, 75 mg/sqm; 8pts) or epirubicin (EPI, 75 mg/sqm; 2pts) infused into the isolated pelvic compartment. Blood samples were collected from the extracorporeal vascular flow and from peripheral plasma, and analysed for drug quantitation. RESULTS: During the procedure, there were no technical or hemodynamic complications, and no deaths occurred during surgery or in the postoperative period. MMC and DOXO peak levels measured in the extracorporeal system which irrotates the tumor area, were on average 21.6 (range: 4.3-44.3, MMC) and 17.2 (range: 1.8-48.4, DOXO) times higher than those observed in the peripheral blood. Similarly; the area under concentration (AUC) versus time curves measured in the pelvic compartment during stop-flow perfusion were 19.9 (range: 3.8-45.0, MMC) and 13.4 (range: 1.2-26.6, DOXO) times higher than the corresponding value in peripheral circulation. The drug percentage eliminated in the ultra filtrate was only 7.7% (MMC) and 0.9% (DOXO), and the plasmatic AUC(0-24) were similar to those observed with iv bolus of equivalent drug doses. Minimal systemic and local toxicities were observed. One complete pathological and 2 partial responses were observed; pain remission in 8/10 patients. median survival was 12 months (8-31). CONCLUSION: The endo-arterial administration into the local vasculature produces high pelvic-systemic concentration gradients during the stop-flow perfusion with limited local and systemic toxicity. The encouraging clinical results suggest further evaluation.

RESUMO

Pain is a highly distressing symptom for patients with advanced cancer. WHO analgesic ladder is widely accepted as a guideline for its treatment. Our aim was to describe pain prevalence among patients diagnosed with advanced non-small-cell lung cancer (NSCLC), impact of pain on quality of life (QoL) and adequacy of pain management. Data of 1021 Italian patients enrolled in three randomised trials of chemotherapy for NSCLC were pooled. QoL was assessed by EORTC QLQ-C30 and LC-13. Analgesic consumption during the 3 weeks following QoL assessment was recorded. Adequacy of pain management was evaluated by the Pain Management Index (PMI). Some pain was reported by 74% of patients (42% mild, 24% moderate and 7% severe); 50% stated pain was affecting daily activities (30% a little, 16% quite a bit, 3% very much). Bone metastases strongly affected presence of pain. Mean global QoL linearly decreased from 64.9 to 36.4 from patients without pain to those with severe pain (P<0.001). According to PMI, 616 out of 752 patients reporting pain (82%) received inadequate analgesic treatment. Bone metastases were associated with improved adequacy and worst pain with reduced adequacy at multivariate analysis. In conclusion, pain is common in patients with advanced NSCLC, significantly affects QoL, and is frequently undertreated. We recommend that: (i). pain self-assessment should be part of oncological clinical practice; (ii). pain control should be a primary goal in clinical practice and in clinical trials; (iii). physicians should receive more training in pain management; (iv). analgesic treatment deserves greater attention in protocols of anticancer treatment.

The present study describes supportive care (SC) in patients with advanced non-small-cell lung cancer (NSCLC), evaluating whether it is affected by concomitant chemotherapy, patient's performance status (PS) and age. Data of patients enrolled in three randomised trials of first-line chemotherapy, conducted between 1996 and 2001, were pooled. The analysis was limited to the first three cycles of treatment. Supportive care data were available for 1185 out of 1312 (90%) enrolled patients. Gastrointestinal drugs (45.7%), corticosteroids (33.4%) and analgesics (23.8%) were the most frequently observed categories. The mean number of drugs per patient was 2.43; 538 patients (45.4%) assumed three or more supportive drugs. Vinorelbine does not produce substantial variations in the SC pattern, while cisplatin-based treatment requires an overall higher number of supportive drugs, with higher use of antiemetics (41 vs 27%) and antianaemics (10 vs 4%). Patients with worse PS are more exposed to corticosteroids (42 vs 30%). Elderly patients require drugs against concomitant diseases significantly more than adults (20 vs 7%) and are less frequently exposed to antiemetics (12 vs 27%). In conclusion, polypharmacotherapy is a relevant issue in patients with advanced NSCLC. Chemotherapy does not remarkably affect the pattern of SC, except for some drugs against side effects. Elderly patients assume more drugs for concomitant diseases and receive less antiemetics than adults.

RESUMO

BACKGROUND: The aim of this study was to determine the maximum tolerated dose (MTD) of liposomal doxorubicin (LD)-vinorelbine (V) in patients with refractory or resistant ovarian cancer. PATIENTS AND METHODS: Thirty patients were eligible. Seven levels were studied [LD 25-V20 (three patients enrolled); LD 30-V20 (three); LD 35-V20 (three); LD 20-V25 (three); LD 25-V25 (three); LD 30-V25 (10); LD 35-V25 (five)]. LD was given on day 1, while V was given on days 1 and 8 every 21 days. Cohorts of three patients were enrolled at each level, and another three patients were planned, if one dose-limiting toxicity (DLT) was registered. RESULTS: DLT was observed in four patients: two febrile neutropenia, one grade 4 thrombocytopenia and one grade 3 palmar-plantar erythrodysesthesia (PPE) at level 7 (LD 35-V25). Thus, liposomal doxorubicin 30 mg/m(2) plus vinorelbine 25 mg/m(2) was the MTD. The most frequent toxicity was neutropenia. Fifteen patients (50%) experienced grade 3 neutropenia and 10 (33.3%) grade 4 neutropenia. Non-hematological toxicity was mild. Mucositis and PPE were the most frequent toxicities, but in most cases were grade 1. Out of 29 assessable patients, six (20.7%; 95% confidence interval 10%-39%) experienced an objective response, with one complete response. CONCLUSIONS: In patients with refractory or resistant ovarian cancer, the recommended doses for the combination studied are liposomal doxorubicin 30 mg/m(2) (day 1) plus vinorelbine 25 mg/m(2) (day 1 and 8). Neutropenia is the most frequent toxicity, while non-hematological toxicity is mild. Substantial activity was recorded and a phase II study is justified.

RESUMO

BACKGROUND: CD40, a member of the tumor necrosis factor receptor superfamily, is capable of mediating the induction of apoptosis in tumors including sarcomas. The expression of proapoptotic receptor contribute to the induction of apoptosis by chemotherapeutic drugs. The present study was undertaken to determine if there is a correlation between the expression of CD40 in spindle-cell sarcomas and the response to epirubicin and ifosfamide chemotherapy. PATIENTS AND METHODS: Immunohistochemical analysis of CD40 expression was performed on 59 paraffin-embedded archival tissues. Evaluation of objective tumor response was carried out according to the WHO criteria. Correlations with response to chemotherapy and baseline patients' characteristics were investigated using Chi-square tests. RESULTS: Positive CD40 staining was observed in 42 tumors; it was expressed in < 10% of cells in 14 (24%), in 10 to 50% in 16 (27%) and in more than 50% of cells in 12 (20%) tumors. No significant association was found between CD40 expression, response to chemotherapy and other clinical and pathological characteristics. CONCLUSION: CD40 expression in spindle-cell soft tissue sarcomas is not associated with response to ifosfamide plus epirubicin chemotherapy.
