Prospective, Multicenter Phase II Trial of Non-Pegylated Liposomal Doxorubicin Combined with Ifosfamide in First-Line Treatment of Advanced/Metastatic Soft Tissue Sarcomas.

Doxorubicin is a widely used anticancer agent as a first-line treatment for various tumor types, including sarcomas. Its use is hampered by adverse events, among which is the risk of dose dependence. The potential cardiotoxicity, which increases with higher doses, poses a significant challenge to its safe and effective application. To try to overcome these undesired effects, encapsulation of doxorubicin in liposomes has been proposed. Caelyx and Myocet are different formulations of pegylated (PLD) and non-pegylated liposomal doxorubicin (NPLD), respectively. Both PLD and NPLD have shown similar activity compared with free drugs but with reduced cardiotoxicity. While the hand-foot syndrome exhibits a high occurrence among patients treated with PLD, its frequency is notably reduced in those receiving NPLD. In this prospective, multicenter, one-stage, single-arm phase II trial, we assessed the combination of NPLD and ifosfamide as first-line treatment for advanced/metastatic soft tissue sarcoma (STS). Patients received six cycles of NPLD (50 mg/m2) on day 1 along with ifosfamide (3000 mg/m2 on days 1, 2, and 3 with equidose MESNA) administered every 3 weeks. The overall response rate, yielding 40% (95% CI: 0.29-0.51), resulted in statistical significance; the disease control rate stood at 81% (95% CI: 0.73-0.90), while only 16% (95% CI: 0.08-0.24) of patients experienced a progressive disease. These findings indicate that the combination of NPLD and ifosfamide yields a statistically significant response rate in advanced/metastatic STS with limited toxicity.

Multicenter Real-World Study on Effectiveness and Early Discontinuation Predictors in Patients With Non-small Cell Lung Cancer Receiving Nivolumab.

BACKGROUND: Real-world (RW) evidence on nivolumab in pretreated patients with non-small cell lung cancer (NSCLC) by matching data from administrative health flows (AHFs) and clinical records (CRs) may close the gap between pivotal trials and clinical practice. METHODS: This multicenter RW study aims at investigating median time to treatment discontinuation (mTTD), overall survival (mOS) of nivolumab in pretreated patients with NSCLC both from AHF and CR; clinical-pathological features predictive of early treatment discontinuation (etd), budget impact (BI), and cost-effectiveness analysis were investigated; mOS in patients receiving nivolumab and docetaxel was assessed. RESULTS: Overall, 237 patients with NSCLC treated with nivolumab were identified from AHFs; mTTD and mOS were 4.2 and 9.8 months, respectively; 141 (59%) received at least 6 treatment cycles, 96 (41%) received < 6 (etd). Median overall survival in patients with and without etd were 3.3 and 19.6 months, respectively (P < .0001). Higher number, longer duration, and higher cost of hospitalizations were observed in etd cases. Clinical records were available for 162 patients treated with nivolumab (cohort 1) and 83 with docetaxel (cohort 2). Median time to treatment discontinuation was 4.8 and 2.6 months, respectively (P < .0001); risk of death was significantly higher in cohort 2 or cohort 1 with etd compared with cohort 1 without etd (P < .0001). Predictors of etd were body mass index <25, Eastern Cooperative Oncology Group performance status >1, neutrophile-to-lymphocyte ratio >2.91, and concomitant treatment with antibiotics and glucocorticoids. The incremental cost-effectiveness ratio of nivolumab was 3323.64 euros ($3757.37) in all patients and 2805.75 euros ($3171.47) for patients without etd. Finally, the BI gap (real-theoretical) was 857 188 euros ($969 050.18). CONCLUSION: We defined predictors and prognostic-economic impact of nivolumab in etd patients.

A Multi-Center, Real-Life Experience on Liquid Biopsy Practice for EGFR Testing in Non-Small Cell Lung Cancer (NSCLC) Patients.

BACKGROUND: circulating tumor DNA (ctDNA) is a source of tumor genetic material for EGFR testing in NSCLC. Real-word data about liquid biopsy (LB) clinical practice are lacking. The aim of the study was to describe the LB practice for EGFR detection in North Eastern Italy. METHODS: we conducted a multi-regional survey on ctDNA testing practices in lung cancer patients. RESULTS: Median time from blood collection to plasma separation was 50 min (20-120 min), median time from plasma extraction to ctDNA analysis was 24 h (30 min-5 days) and median turnaround time was 24 h (6 h-5 days). Four hundred and seventy five patients and 654 samples were tested. One hundred and ninety-two patients were tested at diagnosis, with 16% EGFR mutation rate. Among the 283 patients tested at disease progression, 35% were T790M+. Main differences in LB results between 2017 and 2018 were the number of LBs performed for each patient at disease progression (2.88 vs. 1.2, respectively) and the percentage of T790M+ patients (61% vs. 26%).

Capecitabine in advanced hepatocellular carcinoma: A multicenter experience.

BACKGROUND: Recent data suggest a potential activity and a good tolerability of capecitabine in advanced hepatocellular carcinoma (HCC). AIMS: To evaluate capecitabine activity and safety in a wide cohort of advanced HCC patients. METHODS: Retrospective analysis of 143 capecitabine-treated patients (January 2010 to December 2017) in three centers of the Veneto Oncology Network. RESULTS: Capecitabine was administered in second and third line, but also in first line instead of sorafenib in Child-Pugh B patients (70%), compromised clinical conditions (14%) or contraindications to antiangiogenetics (16%). Median overall survival (OS) and time to progression (TTP) were 6.9 and 2.8 months, respectively. There were no differences in OS and TTP between the 32 patients treated with non-metronomic scheme (2000 mg/day for 14 days) and the 111 patients treated with metronomic scheme (1000 mg/day) after correction for prognostic factors at baseline with a propensity score analysis. Capecitabine was more active in patients intolerant to sorafenib than in those progressing during treatment (p = 0.024). At least one adverse event (mainly hematological) was experienced by 73% of patients but discontinuation was necessary only in 11 (8%). CONCLUSIONS: Capecitabine can be considered an active and safe option in advanced HCC, especially for patients unfit for other treatments.

From Diagnostic-Therapeutic Pathways to Real-World Data: A Multicenter Prospective Study on Upfront Treatment for EGFR-Positive Non-Small Cell Lung Cancer (MOST Study).

INTRODUCTION: Gefitinib, erlotinib, and afatinib represent the approved first-line options for epidermal growth factor receptor (EGFR)-mutant non-small cell lung cancer (NSCLC). Because pivotal trials frequently lack external validity, real-world data may help to depict the diagnostic-therapeutic pathway and treatment outcome in clinical practice. METHODS: MOST is a multicenter observational study promoted by the Veneto Oncology Network, aiming at monitoring the diagnostic-therapeutic pathway of patients with nonsquamous EGFR-mutant NSCLC. We reported treatment outcome in terms of median time to treatment failure (mTTF) and assessed the impact of each agent on the expense of the regional health system, comparing it with a prediction based on the pivotal trials. RESULTS: An EGFR mutation test was performed in 447 enrolled patients, of whom 124 had EGFR mutation and who received gefitinib (n = 69, 55%), erlotinib (n = 33, 27%), or afatinib (n = 22, 18%) as first-line treatment. Because erlotinib was administered within a clinical trial to 15 patients, final analysis was limited to 109 patients. mTTF was 15.3 months, regardless of the type of tyrosine kinase inhibitor (TKI) used. In the MOST study, the budget impact analysis showed a total expense of €3,238,602.17, whereas the cost estimation according to median progression-free survival from pivotal phase III trials was €1,813,557.88. CONCLUSION: Good regional adherence and compliance to the diagnostic-therapeutic pathway defined for patients with nonsquamous NSCLC was shown. mTTF did not significantly differ among the three targeted TKIs. Our budget impact analysis suggests the potential application of real-world data in the process of drug price negotiation. IMPLICATIONS FOR PRACTICE: The MOST study is a real-world data collection reporting a multicenter adherence and compliance to diagnostic-therapeutic pathways defined for patients with epidermal growth factor receptor-mutant non-small cell lung cancer. This represents an essential element of evidence-based medicine, providing information on patients and situations that may be challenging to assess using only data from randomized controlled trials, e.g., turn-around time of diagnostic tests, treatment compliance and persistence, guideline adherence, challenging-to-treat populations, drug safety, comparative effectiveness, and cost effectiveness. This study may be of interest to various stakeholders (patients, clinicians, and payers), providing a meaningful picture of the value of a given therapy in routine clinical practice.

Phytosome complex of curcumin as complementary therapy of advanced pancreatic cancer improves safety and efficacy of gemcitabine: Results of a prospective phase II trial.

A large body of biomedical evidence indicates that activation of Nrf2 by curcumin increases the nucleophilic tone and damps inflammation cumulatively supporting the malignant phenotype. Conversely, genetic analyses suggest a possible oncogenic nature of constitutive Nrf2 activation since an increased nucleophilic tone is alleged increasing chemoresistance of cancer cells. Aiming to contribute to solve this paradox, this study addressed the issue of safety and efficacy of curcumin as complementary therapy of gemcitabine on pancreatic cancer. This was a single centre, single arm prospective phase II trial. Patients received gemcitabine and Meriva®, a patented preparation of curcumin complexed with phospholipids. Primary endpoint was response rate, secondary endpoints were progression free survival, overall survival, tolerability and quality of life. Analysis of inflammatory biomarkers was also carried out. Fifty-two consecutive patients were enrolled. Forty-four (13 locally advanced and 31 metastatic) were suitable for primary endpoint evaluation. Median age was 66 years (range 42-87); 42 patients had Eastern Cooperative Oncology Group performance status 0-1. The median number of treatment cycle was 4.5 (range 2-14). We observed 27.3% of response rate and 34.1% of cases with stable disease, totalizing a disease control rate of 61.4%. The median progression free survival and overall survival were 8.4 and 10.2 months, respectively. Higher IL-6 and sCD40L levels before treatment were associated to a worse overall survival (p < 0.01). Increases in sCD40L levels after 1 cycle of chemotherapy were associated with a reduced response to the therapy. Grade 3/4 toxicity was observed (neutropenia, 38.6%; anemia, 6.8%). There were no significant changes in quality of life during therapy. In conclusion, the complementary therapy to gemcitabine with phytosome complex of curcumin is not only safe but also efficiently translate in a good response rate in first line therapy of advanced pancreatic cancer.

Circulating endothelial cells and risk of progression in patients with hepatocellular cancer receiving sorafenib.

AIM: We investigated the behavior of circulating endothelial cells (CEC) in patients with hepatocellular carcinoma (HCC) receiving sorafenib, and whether CEC levels were associated with time to progression (TTP). MATERIALS & METHODS: CECs in advanced HCC patients receiving sorafenib were counted at baseline and every 4 weeks. RESULTS: Twenty four HCC patients were enrolled in the study. Median TTP was 3.2 months (1-6). Median baseline CEC levels were 67 cells/ml, with an increase of 169.8% after 4 weeks of treatment. Any time CEC levels in patients with a TTP lower than 4 months were higher, but not statistically significant, compared with those in patients with TTP more than 4 months. CONCLUSION: Treatment with sorafenib changed CEC levels in HCC patients.

[Therapeutic decisions and treatment with sorafenib in hepatocellular carcinoma: final analysis of GIDEON study in Italy]. / Scelte terapeutiche e trattamento con sorafenib nell'epatocarcinoma: analisi finale dello studio GIDEON in Italia.

INTRODUCTION: Sorafenib, an oral multikinase inhibitor, is the only targeted agent approved for the treatment of patients with hepatocellular carcinoma (HCC) after demonstration to increase overall survival compared to placebo in two randomized phase III study. GIDEON (Global Investigation of therapeutic DEcisions in HCC and Of its treatment with sorafeNib) is the largest, global, non-interventional, prospective study of patients with uHCC (n>3200) treated with sorafenib in real-life clinical practice conditions. Here we report the final analysis of safety and efficacy in the Italian cohort of patients. METHODS: Patients with unresectable HCC who are candidates for systemic therapy, and for whom a decision has been made to treat with sorafenib, are eligible for inclusion. Patients demographics disease characteristics and treatment history were recorded at baseline visit. Sorafenib dose, concomitant medications, performance status, liver function, adverse events and efficacy (survival and response rate) were collected throughout the study. RESULTS: In the Italian cohort of the GIDEON study 278 patients were included in 36 centers. The global rate of adverse events was 81%. Drug-related events accounted for 67%, mostly of grade 1 and 2, and only 8% were classified as serious. The most common were diarrhea (24%), fatigue (23%), dermatological (14%), rash/exfoliation (10%), hypertension (9%), hemorrage/bleeding of gastrointestinal tract (6%). Overall survival was 14.4 months and time to progression 6.2 months. Objective responses were observed in 14 patients (5%) with 3 complete responses (1%). Stable diseases of at least 6 weeks were observed in 113 patients (41%) with a 30% of disease control rate. DISCUSSION: The safety profile of sorafenib in terms of rate and type of adverse events is similar to that emerged in the global international GIDEON study as well as in the pivotal registration studies.

Clinical governance benchmarking issues in oncology: aggressiveness of cancer care and consumption of strong opioids. A single-center experience on measurement of quality of care.

AIMS AND BACKGROUND: The aggressiveness of cancer care near the end of life and the consumption of opioids are potential indicators of quality of care in palliative and end-of-life settings. The purpose of this article is to present a retrospective analysis regarding these themes and the adopted procedures to improve quality of care. METHODS: We evaluated all cancer patients treated and deceased during 2008 and considered those who died and received any antiblastic therapy within 14 and 30 days prior to death. Moreover, we evaluated the annual consumption of pure opioids during 2007 and 2008 in our inpatient clinic. We found that 5% and 9% of all treated patients were still receiving antiblastic treatment near the end of life within respectively 14 and 30 days prior to death (respectively 29.6% and 51.5% of deceased patients). All but 2 patients died from progressive disease, one patient died from acute myocardial infarction during chemotherapy, and one of severe sepsis after chemotherapy for non-Hodgkin lymphoma. As regards the annual consumption of strong opioids, there was a 179% increase in the use of morphine-equivalent doses of oral long-acting opioids (+228% for oxycodone) after the introduction of daily pain measurement through a numerical rating scale. CONCLUSIONS: To reduce the administration of chemotherapy near the end of life, we introduced the palliative prognostic score, to be administered to all advanced cancer patients with performance status of at least 2. To evaluate the effectiveness of analgesics and to reduce the cases of undertreatment of cancer pain, we adopted, in addition to the numerical rating scale, Cleeland's Pain Management Index. We are convinced that attempts to improve the quality of care can be achieved by the collaboration of all health professionals, patients and care givers.

Ifosfamide encephalopathy and use of methylene blue. A case report of different sequential neurotoxicity.

Neurotoxicity is a clinically relevant adverse event observed with the use of ifosfamide. It is usually mild, occasionally severe and seldom fatal. Ifosfamide-induced encephalopathy requires interruption of chemotherapy, intravenous hydration and administration of methylene blue. Less is known about the efficacy of methylene blue in avoiding a second episode of ifosfamide-induced encephalopathy while maintaining chemotherapy with ifosfamide. We report a case of a different clinical manifestation of ifosfamide-induced encephalopathy after continued ifosfamide use and despite methylene blue in a patient with retroperitoneal sarcoma.

Intraarterial hepatic chemoembolization of liver metastases from colorectal cancer adopting irinotecan-eluting beads: results of a phase II clinical study.

Since November 2005 a clinical trial of intraarterial hepatic chemoembolization (TACE) with irinotecan-eluting beads has been ongoing in 20 patients affected by liver metastases from colorectal cancer in a palliative setting. A high response rate (80%), with reduction of lesional contrast enhancement in all responding patients was found. The procedure was well tolerated by most patients, with a median duration of hospitalization of 3 days (range 1-10 days). The most important adverse event was abdominal pain during the injection. Adequate supportive treatment with antibiotic and antiemetic prophylaxis, dexamethasone, and intravenous hydration is strictly necessary until the serum levels of transaminases are stabilized and in order to prevent infections. Major analgesics such as morphine must be used before and after the procedure. Our results suggest that TACE using irinotecan-eluting beads is feasible and active in pretreated patients with liver metastases from CRC.

Hepatic arterial chemotherapy in combination with systemic chemotherapy compared with hepatic arterial chemotherapy alone for liver metastases from colorectal cancer: results of a multi-centric randomized study.

Hepatic arterial infusion (HAI) chemotherapy is accepted to be an option in patients with non-resectable metastases from colorectal cancer confined to the liver. In a multi-istitutional trial, 76 patients were randomly assigned to receive HAI versus HAI plus systemic bolus 5-fluorouracil and leucovorin. The primary endpoint was survival, followed by response, recurrence and toxicity. Survival was longer for HAI plus systemic chemotherapy (HAI+SYC) than HAI (median, 20 vs. 14 months; p = 0.0033), as were responses (47.5% and 41.7%; p = 0.09) and time to hepatic progression (12 vs. 8 months; p = 0.039). Side effects included haematological toxicity that was mostly mild and reversible in 432 cases. Neutropenia grade 3 occurred in four patients in the HAI+SYC arm and one in the HAI arm. Diarrhoea occurred in 20% and 7% of patients and stomatitis occurred in 18% and 2%, respectively. On the contrary biliary toxicity was significant; twelve patients had evidence of bilirubin elevations of more than 3 mg/dl (six in each arm), and two had asymptomatic arterial biliary-tree fistulae: one in the HAI+SYC arm and one in the HAI arm. Grade 3 elevation in alkaline phosphatase and aminotransferase levels occurred in 26% and 24%, respectively. In conclusion, the combination of HAI+SYC is active and safe showing a clinical advantage with respect to simple HAI, increasing overall survival, response rate and time to progression.

A phase II clinical study on relapsed malignant gliomas treated with electro-hyperthermia.

The purpose of this study was to evaluate the activity and toxicity of electro-hyperthermia (ET) on relapsed malignant glioma patients. Twelve patients with histologically diagnosed malignant glioma entered the study. Eight patients had glioblastoma multiforme, two had anaplastic astrocytoma grade III and two had anaplastic oligodendroglioma. All patients were pre-treated with temozolamide-based chemotherapy and radiotherapy. Hyperthermia with short radiofrequency waves of 13.56 MHz was applied using a capacitive coupling technique keeping the skin surface at 20 degrees C. The applied power ranged between 40-150 Watts and the calculated average equivalent temperature in the tumours was above 40 degrees C for more than 90% of the treatment duration. One complete remission and 2 partial remission were achieved, with a response rate of 25%. The median duration of response was 10 months (range 4-32). The median survival of the entire patient population was 9 months, with 25% survival rate at 1 year. ET appears to have some effectiveness in adults with relapsed malignant glioma.

Prevention and therapy of neutropenia in elderly patients.

Standard chemotherapy in elderly patients is still nowadays a difficult issue, due to the fact that marrow reserve decrease with age and the results might lead to higher toxicity of otherwise well tolerated regimen and schedule. In the literature, very few data exist of myelosuppression in patients with solid tumors, while more data have been published on non-Hodgkin's lymphoma. The burden of toxicity increase with age, leading to the fact that some patients with curable or sensitive disease do not receive appropriate treatment. One of the ways to try to circumvent neutropenia is the prophylactic use of haematopoietic growth factors with the double aim of maintaining dose-intensity and reducing toxicity. This paper will describe the patterns of marrow toxicity in treating elderly patients with cancer and the role of haematopoietic growth factors.

A high cytosol value of urokinase-type plasminogen activator (uPA) may be predictive of early relapse in primary breast cancer.

BACKGROUND: There is now much data that suggest a relationship between angiogenesis and breast cancer prognosis. Angiogenesis is a multistep process resulting from an ordered set of events and regulated by positive and negative modulators of microvessels growth and by the expression of various proteolytic enzymes. MATERIALS AND METHODS: We prospectively evaluated VEGF and microvessels density on tumor specimen and cytosolic levels of uPA and PAI-1. RESULTS: We enrolled 81 primary breast cancer patients. The median follow-up was 38 months. Using the median value as cutoff for the statistical analysis, we found significant correlation between cytosolic levels of uPA and PAI-1 (r = 0.61; p < .0001), between VEGF and steroid hormone receptor status (p = .01), between PAI-1 and tumor grading (p = .009), and between uPA and tumor size greater than 1 cm (p = .04). With respect to the prognosis, we observed a significant correlation between low uPA levels and RFS and an unforeseen, direct correlation between high VEGF values and better RFS. CONCLUSIONS: Our preliminary results indicate that the cytosolic level of uPA at diagnosis may be predictive of early relapse in primary breast cancer.

Bolus fluorouracil and leucovorin with oxaliplatin as first-line treatment in metastatic colorectal cancer.

PURPOSE: A phase II trial investigated the activity and toxicity of a bolus administration schedule of oxaliplatin, fluorouracil (5-FU), and leucovorin (LV) therapy in patients with untreated advanced colorectal cancer. PATIENTS AND METHODS: Forty-five patients in this multicenter, open, nonrandomized study received oxaliplatin 130 mg/m(2) on the first day of each course and 5-FU and LV 350 mg/m(2) and 20 mg/m(2), respectively, as a daily bolus for 5 days, every 21 days, for a maximum of six courses. RESULTS: Partial responses occurred in 18 patients, giving an intent-to-treat response rate of 40.0%. Median time to response was 12.7 weeks; median duration of response was 18.4 weeks. Median progression-free survival was 5.9 months; median survival was 14 months. The independent prognostic factors for improved overall survival were good performance status and negative carcino-embryonic antigen blood level. Incidences of adverse effects were reduced after the 5-FU dose was reduced to 300 mg/m(2). Reversible neurologic toxicity occurred in 44.4% of patients. CONCLUSION: Bolus administration of oxaliplatin, 5-FU, and LV as first-line therapy for untreated advanced colorectal cancer is efficacious and safe. In addition to a more favorable safety profile, the 300 mg/m(2) dosage offered improved dose-intensity compared with the initial dosage.
