Abstract
BACKGROUND The use of anthracyclines in metastatic breast cancer (MBC) is limited by cumulative dose-dependent cardiotoxicity mostly in elderly women with comorbidities. The aim of this observational retrospective study was to evaluate the efficacy of non-pegylated liposomal doxorubicin (Myocet®) and cyclophosphamide in elderly women as HER2 negative first-line MBC treatment. METHODS 84 elderly women >70 years of age (median age 78 years) with MBC HER2 negative were enrolled. Performance Status in 58 patients was ECOG-0 and in 26 patients was ECOG-1. RESULTS The drug was well tolerated, with overall response rates were >40%, median overall survival was 16.2 months (95%CI:14.6-18.8) and median progression free survival was 5.8 months (95%CI:4.4-8.6). Hematologic toxicity with neutropenia was the most frequent adverse event, but the treatment was well tolerated maintained a manageable cardiotoxicity. CONCLUSION Non-pegylated liposomal doxorubicin may represent a valid therapeutic option in first-line for elderly patients with HER/2 negative MBC improving survival, anti-tumor response rate and de-creases cardiotoxicity.

Abstract
OBJECTIVE The outbreak of coronavirus disease 2019 (COVID-19) has affected the treatment of cancer patients, with particular regard to the management of both chemotherapy and side effects. Chemotherapy-induced nausea and vomiting (CINV) are amongst the most troublesome side effects that impair patients' adherence to treatments and their quality of life (QoL). NEPA (Akynzeo®), is an oral fixed-dose combination of netupitant [a neurokinin-1 receptor antagonist (NK1RA), 300 mg] and palonosetron [(5-hydroxytryptamine (serotonin or 5HT) type3 receptor antagonist (5HT3RA), 0.5 mg] which has been shown to be effective in preventing CINV. PATIENTS AND METHODS This prospective study started before the outbreak of COVID-19 and was carried out during the pandemic period. The aim was to evaluate the efficacy and safety of a single oral dose NEPA plus 12 mg of dexamethasone (DEX) in patients treated with Folfoxiri plus Bevacizumab and Folfirinox. The patients were diagnosed with advanced colorectal cancer (CRC) or advanced pancreatic ductal adenocarcinoma (PDAC). They were divided into two groups: naïve patients and patients previously treated with serotonin receptor antagonists (5HT3-RA) and neurokin-1 receptor antagonists (NK1-RA). RESULTS During the overall phase, the complete response (CR) rate was 96.8% in naïve patients treated with Folfoxiri plus Bevacizumab, and 94.6% in patients treated with Folfirinox. During the acute and delayed phases, the CR rate was 92.8% and 94.2%, with Folfoxiri and Bevacizumab, as well as 96.2% and 94.6%, with Folfirinox. There was no adequate control of CINV events in patients on antiemetic prophylaxis with 5HT3-RA or NK1-RA associated with cortisone. During the overall phase, the CR rate was 74.6% with Folfoxiri plus Bevacizumab and 75.8% with Folfirinox. During the acute and delayed phases, the CR rate was 72.5% and 74.8% with Folfoxiri plus Bevacizumab, as well as 75.2% and 74.6% with Folfirinox. CONCLUSIONS This study has shown the therapeutic benefits of NEPA in the management and prophylaxis of CINV events, both in naive patients and patients previously treated with 5HT3-RA and NK1-RA. In addition, NEPA has been shown to be safe, both before and during the COVID-19 pandemic.

Abstract
OBJECTIVE Eribulin mesylate (Halaven®) is a non-taxane inhibitor of microtubule indicated as monotherapy in patients with metastatic breast cancer (MBC), which progresses after anthracycline and taxanes therapy. In this retrospective observational study, we want to evaluate the efficacy of Eribulin in elderly women with MBC pretreated with anthracyclines and taxanes. PATIENTS AND METHODS 40 elderly patients > 70 years of age were enrolled, and the median age was 76 years (range 70-82). Overall survival (OS), Progression Free Survival (PFS), Objective Response Rate (ORR) were primary endpoints, tolerability, carcinoembryonic antigen levels 15.3 (Ca 15.3), before and after treatment, and Quality of Life (QoL) were secondary endpoints. RESULTS Eribulin treatment was well tolerated, produced a good level of disease control, a manageable toxicity profile and a significant impact on QoL. Median OS was 12.8 months and median PFS was 3.2 months. A significant correlation was observed between reduction of Ca 15.3 and PFS with a value of 0.59 (p = 0.002). CONCLUSIONS Despite a limited number of patients and a modest manageable toxicity, Eribulin is a chemotherapy treatment that has showed to be an effective and well-tolerated therapeutic option in elderly patients with MBC. Further analysis should focus on the elderly patients in our setting of study.

Abstract
Background Nivolumab is an anti-PD-1 antibody that restores the antitumour immune function of T cells, blocking the binding of PD-1 with its ligand PD-L1. PD-1 is expressed on T cells and interacts with PD-L1 on tumour cells. The PD-1-PD-L1 link inhibits T cell activation. In metastatic melanoma, PD-1-PD-L1 binding plays a critical role, and the advent of the immune checkpoint inhibitor nivolumab has delivered new and effective treatment options with proven clinical benefit. In the present study, we evaluated the efficacy of nivolumab in elderly patients with metastatic melanoma. Methods The study enrolled 55 elderly patients (75 years of age and older) with a diagnosis of metastatic melanoma. Primary endpoints of the study were progression-free survival (pfs) and the objective response rate; secondary endpoints were overall survival, reduction in serum lactate dehydrogenase (ldh) from before to after treatment, and tolerability. Results Nivolumab was well tolerated and resulted in good disease control, with a manageable toxicity profile and significant clinical benefit. The duration of pfs was 5.1 months (95% confidence interval: 3.5 months to 6.8 months). A significant correlation was observed between reduction in serum ldh and pfs: 0.60 (95% confidence interval: 0.28 to 0.86; p = 0.002). Conclusions Nivolumab is an immunotherapy treatment that has proved to be an effective and well-tolerated therapeutic option in elderly patients with metastatic melanoma.

Abstract
Aims and Background Rarely are conclusions from clinical trials summarized in international consensus conferences and promptly transferred to patient care. The adjuvant therapy for colorectal cancer used in daily clinical practice in Italy is described and compared with the recommendations of the 1990 NIH Consensus Conference. Patients and Methods We audited prescriptions of adjuvant systemic therapies for Italian colorectal cancer patients in 82 centers during a fixed one-week period. Results Among 434 patients receiving adjuvant chemotherapy there were 139 (42.5%) colon cancer patients with N- and 169 (51.7%) with N+ regional nodal involvement. Treatment at academic centers, a young age, T4 and a low total number of lymph nodes removed at surgery were the factors potentially justifying the decision for adjuvant chemotherapy in stage II colon cancer patients. The most common chemotherapy used was a bolus of 5-fluorouracil/folinic acid for 6 months (75.8%). Adjuvant radiotherapy was not administered to 37 (38.5%) of 96 patients with stage II and III rectal cancer. Conclusions The study shows that a substantial proportion of patients on adjuvant treatment at a certain time point in a large enough sample of Italian centers are stage II (potential over-treatment) and that an under-treatment of stage II and III rectal cancer patients (lack of radiotherapy) occurs too often in daily clinical practice in this country.

Abstract
Tailoring the structural and electronic properties of 2D materials is fundamental to boost their use in a wide range of technological applications. In this paper, by means of first principles simulations, we show how methyl functionalization of MoS2 and WS2 monolayers can be employed to change their energy gap, tune their optoelectronic properties and modify the relative stability of their structural phases (or polytypes). In particular for both compound monolayers, we find that the most stable semiconducting H phase becomes metallic upon methyl functionalization, while in the metastable T' phase the band gap increases as a function of the -CH3 coverage; correspondingly the phase stability is reversed and the on-set of the optical absorption is blue-shifted.

Abstract
γδ T cells usually infiltrate many different types of cancer, but it is unclear whether they inhibit or promote tumor progression. Moreover, properties of tumor-infiltrating γδ T cells and those in the corresponding normal tissue remain largely unknown. Here we have studied features of γδ T cells in colorectal cancer, normal colon tissue and peripheral blood, and correlated their levels with clinicopathologic hallmarks. Flow cytometry and transcriptome analyses showed that the tumor comprised a highly variable rate of TILs (5-90%) and 4% γδ T cells on average, with the majority expressing Vδ1. Most Vδ1 and Vδ2 T cells showed a predominant effector memory phenotype and had reduced production of IFN- γ which was likely due to yet unidentified inhibitory molecules present in cancer stem cell secretome. Transcriptome analyses revealed that patients containing abundant γδ T cells had significantly longer 5-year disease free survival rate, suggesting their efficacy in controlling tumor at very early stage.

Abstract
Oncological Genetic Counselling (CGO) allows the identification of a genetic component that increases the risk of developing a cancer. Individuals' psychological reactions are influenced by both the content of the received information and the subjective perception of their own risk of becoming ill or being a carrier of a genetic mutation. This study included 120 participants who underwent genetic counselling for breast and/or ovarian cancer. The aim of the study was to examine the relation between their cancer risk perception and the genetic risk during CGO before receiving genetic test results, considering the influence of some psychological variables, in particular distress, anxiety and depression. Participants completed the following tools during a psychological interview: a socio-demographic form, Cancer Risk Perception (CRP) and Genetic Risk Perception (GRP), Hospital Anxiety and Depression Scale (HADS) and Distress Thermometer (DT). The data seem to confirm our hypothesis. Positive and significant correlations were found between the observed variables. Moreover, genetic risk perception determined an increase in depressive symptomatology and cancer risk perception led to an increase in anxious symptomatology, specifically in participants during cancer treatment. The present results suggest the importance of assessing genetic and cancer risk perception in individuals who undergo CGO, to identify those who are at risk of a decrease in psychological well-being and of developing greater psychological distress.

Abstract
The inhibition of the mechanisms of tumor neo-angiogenesis represents a milestone that in the last 10 years has seen the advent of numerous molecules to target action against the vascular endothelial growth factor (VEGF). More recently, new molecules have been developed that inhibit tumor spread by the blockade of specific VEGF receptors (VEGFRs), thereby preventing the binding of a ligand to its receptor and the cascade of proliferative events downstream. Ramucirumab is a fully humanized IgG1 monoclonal antibody that performs its action by blocking the isoform 2 of the VEGF receptor (VEGFR-2). Numerous preclinical and clinical studies have demonstrated its activity in several solid tumors, demonstrating a remarkable efficacy in terms of progression-free survival and overall survival in addition to a favorable toxicity profile. This review analyzes in detail the role of ramucirumab in the treatment of advanced gastric and gastroesophageal junction cancers.

Abstract
Although generally ascribed to the presence of defects, an ultimate assignment of the different contributions to the emission spectrum in terms of surface states and deep levels in ZnO nanostructures is still lacking. In this work we unambiguously give first evidence that zinc vacancies at the (1010) nonpolar surfaces are responsible for the green luminescence of ZnO nanostructures. The result is obtained by performing an exhaustive comparison between spatially resolved cathodoluminescence spectroscopy and imaging and ab initio simulations. Our findings are crucial to control undesired recombinations in nanostructured devices.

Abstract
Nanowires made of materials with non-centrosymmetric crystal structures are expected to be ideal building blocks for self-powered nanodevices due to their piezoelectric properties, yet a controversial explanation of the effective operational mechanisms and size effects still delays their real exploitation. To solve this controversy, we propose a methodology based on DFT calculations of the response of nanostructures to external deformations that allows us to distinguish between the different (bulk and surface) contributions: we apply this scheme to evaluate the piezoelectric properties of ZnO [0001] nanowires, with a diameter up to 2.3 nm. Our results reveal that, while surface and confinement effects are negligible, effective strain energies, and thus the nanowire mechanical response, are dependent on size. Our unified approach allows for a proper definition of piezoelectric coefficients for nanostructures, and explains in a rigorous way the reason why nanowires are found to be more sensitive to mechanical deformation than the corresponding bulk material.

Abstract
Guillain-Barré Syndrome (GBS) is a demyelinating polyneuropathy of probable autoimmune pathogenesis characterized by rapidly progressive symmetric paralysis. In the literature some cases of GBS associated with anticancer chemotherapy are reported. We present a case of a 55-year old woman who complained of progressive motor deficit in four limbs, areflexia in lower limbs and facial nerve paralysis one week after beginning cisplatin-gemcitabine chemotherapy for metastatic lung cancer. The cerebrospinal fluid analysis showed a strong positive Pandy reaction with 435 mg/dl total protein. The electromyography and the electroneuronography established the diagnosis of inflammatory demyelinating polyneuropathy. Specific therapy with intravenous immunoglobulin 25 g/day in 5 administrations for 5 days was started with complete benefit.

Abstract
Zoledronic acid is a bisphosphonate that is effective in the treatment of complications of metastatic bone disease. We have carried out a perspective study on 24 consecutive patients with prostate cancer metastatic to bone to verify the effect of zoledronic acid on analgesic response and a possible relationship with the levels of bone metabolism biomarkers. Eligibility for this study required prostate cancer patients with metastatic bone disease and pain not controlled by analgesics. Patients were excluded from the study if they were receiving cytotoxic chemotherapy or radiation therapy within three months. Eighteen patients (75%) were considered responder to acid zoledronic, only 6 patients did not respond. Before starting treatment (T0) mean Visual Analogue Scale was 7.8 (SE +/- 0.29), after 1 month therapy (T1) was 3.6 (SE +/- 0.3) and after three months (T2) was 3.1 (SE +/- 0.4) with a significant difference between T0 and T1 (p<0.0005) and between T0 and T2 (p<0.0005). Visual Analogue Scale improvement was positively correlated with decrease of C-telopeptide and bone phosphatase alkaline (p<0.05) serum levels.

Abstract
Recently, the hypothesis that colorectal tumors originate from a subpopulation of cells called ‘cancer stem cells' (CSCs) or tumor-initiating cells, which exhibit stem-like features, has been confirmed experimentally in various human cancers. Several studies have confirmed the existence of colorectal CSCs (CRCSCs) and have demonstrated that this rare cell population can be isolated by the expression of specific cell surface biomarkers. MicroRNAs (miRNAs) are a class of small non-coding RNAs, which are crucial for post-transcriptional regulation of gene expression and participate in a wide variety of biological functions, including development, cell proliferation, differentiation, metabolism and signal transduction. Moreover, new evidences suggest that miRNAs could contribute to preserve stemness of embryonic stem cells and could be involved in maintaining stemness of CSCs. Recent studies have begun to outline the role of miRNAs in regulation of CRCSCs. This review aims to summarize the recent advancement about the roles of miRNAs in CRCSCs that may represent a step forward in understanding the molecular mechanisms and the possible approaches for colorectal cancer therapy.

Abstract
BACKGROUND Scientific data provide the evidence that secondary K-RAS mutations do not occur during anti-epidermal growth factor receptor therapy in colorectal cancer patients. This multicenter phase II prospective study aims to investigate the activity of a retreatment with a cetuximab-based therapy. PATIENTS AND METHODS We enrolled 39 irinotecan-refractory patients who had a clinical benefit after a line of cetuximab- plus irinotecan-based therapy and then a progression of disease for which underwent a new line chemotherapy and finally, after a clear new progression of disease, were retreated with the same cetuximab- plus irinotecan-based therapy. RESULTS Median number of therapeutic lines before accrual was 4. Median interval time between last cycle of first cetuximab-based therapy and first cycle of the retreatment was 6 months. Overall response rate was 53.8% with 19 partial responses (48.7%) and 2 complete responses (5.1%). Disease stabilization was obtained in 35.9% of patients and progression in four patients (10.2%). Median progression-free survival was 6.6 months. The correlation between skin toxicity during first cetuximab therapy and during cetuximab rechallenge was significant (P = 0.01). CONCLUSION Rechallenge with the same cetuximab-based therapy may achieve a new important clinical benefit further delaying the progression of disease and improving the therapeutic options.

Abstract
Ulcerative colitis (UC) is a form of inflammatory bowel disease (IBD) characterized by damage of large bowel mucosa and frequent extra-intestinal autoimmune comorbidities. The role played in IBD pathogenesis by molecular chaperones known to interact with components of the immune system involved in inflammation is unclear. We previously demonstrated that mucosal Hsp60 decreases in UC patients treated with conventional therapies (mesalazine, probiotics), suggesting that this chaperonin could be a reliable biomarker useful for monitoring response to treatment, and that it might play a role in pathogenesis. In the present work we investigated three other heat shock protein/molecular chaperones: Hsp10, Hsp70, and Hsp90. We found that the levels of these proteins are increased in UC patients at the time of diagnosis and decrease after therapy, supporting the notion that these proteins deserve attention in the study of the mechanisms that promote the development and maintenance of IBD, and as biomarkers of this disease (e.g., to monitor response to treatment at the histological level).

Abstract
AIMS AND BACKGROUND We investigated the efficacy of docetaxel plus prednisone in Italian patients with metastatic hormone-refractory prostate cancer (mHRPC). METHODS Twenty four patients with mHRPC received docetaxel 75 mg/m2 every 3 weeks plus prednisone 5 mg twice daily for up to six cycles. The primary endpoint was efficacy measured by a reduction in serum prostate specific antigen (PSA) levels and measurable disease. Evaluation of toxicity, quality of life and reduction of pain were secondary endpoints. RESULTS PSA response was seen in 18 patients (75%). We observed a partial response in 2 patients (8.3%), stable disease in 10 patients (41.7%), and disease progression in 12 patients (50%). Severe neutropenia was reported in 12.5% of patients. CONCLUSIONS Treatment with docetaxel every three weeks is an effective and well tolerated therapeutic option in patients with mHRPC.

Abstract
The potent anti-tumour activities of gammadelta T cells have prompted the development of protocols in which gammadelta-agonists are administered to cancer patients. Encouraging results from small Phase I trials have fuelled efforts to characterize more clearly the application of this approach to unmet clinical needs such as metastatic carcinoma. To examine this approach in breast cancer, a Phase I trial was conducted in which zoledronate, a Vgamma9Vdelta2 T cell agonist, plus low-dose interleukin (IL)-2 were administered to 10 therapeutically terminal, advanced metastatic breast cancer patients. Treatment was well tolerated and promoted the effector maturation of Vgamma9Vdelta2 T cells in all patients. However, a statistically significant correlation of clinical outcome with peripheral Vgamma9Vdelta2 T cell numbers emerged, as seven patients who failed to sustain Vgamma9Vdelta2 T cells showed progressive clinical deterioration, while three patients who sustained robust peripheral Vgamma9Vdelta2 cell populations showed declining CA15-3 levels and displayed one instance of partial remission and two of stable disease, respectively. In the context of an earlier trial in prostate cancer, these data emphasize the strong linkage of Vgamma9Vdelta2 T cell status to reduced carcinoma progression, and suggest that zoledronate plus low-dose IL-2 offers a novel, safe and feasible approach to enhance this in a subset of treatment-refractory patients with advanced breast cancer.

Abstract
BACKGROUND Mammaglobin is expressed mainly in mammary tissue, overexpressed in breast cancer (BC) and rarely in other tissue. The aim of this study was to assess the sensitivity and specificity of transcript MGB1 detection and to evaluate the role of MGB1 as potential clinical marker for the detection of disseminated cancer cells in the blood of BC patients. PATIENTS AND METHODS A consecutive series of 23 BC tissues, 36 peripheral blood BC samples and 35 healthy peripheral blood samples was prospectively recruited to investigate MGB1 expression by means of a quantitative Real Time RT-PCR assay. RESULTS MGB1 overexpression in tissue samples of BC patients is significantly associated only with high level of Ki67 (P <0.05). None of the samples from peripheral blood of 35 healthy female individuals were positive for MGB1 transcript. In contrast MGB1 mRNA expression was detected in three of 36 (8%) peripheral blood of BC patients. CONCLUSIONS Our preliminary results demonstrate that the detection of MGB1 transcript in peripheral blood of BC patients was specific but with low sensitivity. MGB1 overexpression by itself or in combination with Ki67 might be considered an index of BC progression.

Abstract
BACKGROUND Methylation of the p16 promoter is one of the most frequent mechanisms of gene inactivation; its incidence is extremely variable according to the type of tumor involved. Our purpose was to analyze the hypermethylation of the p16 promoter in laryngeal squamous cell carcinomas (LSCC), salivary gland (SG) tumors and in colorectal cancer (CRC), to detect any possible association with the clinicopathological features and to determine the prognostic significance of the p16 gene in the tumors analyzed. PATIENTS AND METHODS The hypermethylation of the p16 promoter was prospectively analyzed, by MSP, in a consecutive series of 64 locally advanced LSCC patients, in a consecutive series of 33 SG tumor patients and in a consecutive series of 66 sporadic CRC patients. RESULTS Hypermethylation was observed in 9% of the LSCC cases, in all cases of SG cancer and in 21% of the CRC cases. No significant association was observed between p16 hypermethylation and clinicopathological variables in all the tissue samples analyzed. Moreover at univariate analysis p16 mutations were not independently related at disease relapse and death in LSCC and CRC. CONCLUSIONS The results of this study suggest that the lack of p16 function could happen in advanced stage of SG tumors.

Abstract
BACKGROUND Although Ki-ras and TP53 mutations have probably been the genetic abnormalities most exhaustively implicated and studied in colorectal cancer (CRC) progression, their significance in terms of disease relapse and overall survival has not yet clearly been established. PATIENTS AND METHODS A prospective study was carried out on paired tumor and normal colon tissue samples from a consecutive series of 160 previously-untreated patients, undergoing resective surgery for primary operable sporadic CRC. Mutations within the TP53 (exons 5-8) and Ki-ras (exon 2) genes were detected by PCR-SSCP analyses following sequencing. RESULTS Mutation analyses of exons 5 to 8 of the TP53 gene showed mutations in 43% (68/160) of the cases, while mutation analyses of exon 2 of the Ki-ras gene showed mutations in 46% (74/160) of the cases. Multivariate analyses showed that clinical outcome were strongly associated with the presence of specific TP53 mutations in L3 domain alone (only in DFS) or in combination with specific Ki-ras mutations at codon 13. CONCLUSION Specific TP53 mutations in L3 domain alone (only in DFS) or in combination with specific Ki-ras mutations at codon 13 are associated with a worse prognosis in sporadic CRC.

Abstract
Gastrointestinal stromal tumors (GISTs) are mesenchymal tumors of the gastrointestinal tract that are believed to originate from a neoplastic transformation of the intestinal pacemaker cells (interstitial cells of Cajal) normally found in the bowel wall or their precursors. Although the microscopic features have been known for a long time, the defining characteristic of GIST is the presence of the cell-surface antigen CD117 (KIT), which is demonstrated by immunohistochemistry. KIT, which is a growth factor transmembrane receptor, is the product of the proto-oncogene c-kit (chromosome 4). Surgical removal remains the only curative treatment for patients with GISTs. Tumor size, mitotic index, anatomic location, tumor rupture and disease-free interval are the classic characteristics used to predict the clinical course of patients who undergo complete gross resection. Most GISTs express constitutively activated mutant isoforms of KIT or kinase platelet-derived growth factor receptor alpha (PDGFRA) that are potential therapeutic targets for imatinib mesylate. Imatinib mesylate is a rationally designed, molecularly specific oral anticancer agent that selectively inhibits several protein tyrosine kinases central to the pathogenesis of human cancer and which has demonstrated remarkable clinical efficacy in patients with chronic myeloid leukemia and malignant GISTs. More recently Sunitinib, a new KIT/PDGFRA kinase inhibitor, has been tested in patients with GIST resistant to imatinib, with promising results.

Abstract
We carried out a phase II nonrandomized study to examine the level of activity of oxaliplatin, pegylated liposomal doxorubicin, and cyclophosphamide in a patient population with relapsed ovarian cancer pretreated with platinum derivatives and paclitaxel. Patients received oxaliplatin (85 mg/m2), pegylated liposomal doxorubicin (30 mg/m2), and cyclophosphamide (750 mg/m2). A total of 49 patients (39 assessable for toxicity and response) were enrolled in this trial. Neutropenia grade 3 was observed in six patients (15%) and anemia grade 3 in one patient (0.2%). Fatigue grade 1-2 occurred in 26 patients (66%), nausea/vomiting grade 1 in 23 patients (58%), and alopecia grade 1-2 in 19 patients (48%). Twenty-one (53%) patients experienced grade 1-2 peripheral neuropathy. The overall response rate was 46% (95% CI 23.6-68.7). Median progression-free survival was 28 weeks (range 12-52 weeks) and median survival was 45 weeks (range 26-136+ weeks). The mean duration of response was 34 weeks (range 16-52 weeks). In platinum-resistant and -refractory ovarian cancer patients, the overall response rate was 37% (CI 95% 14.4-60.8) with a progression-free survival of 28 weeks (range 12-52 weeks) and a median survival of 42 weeks (range 28-84 weeks). This combination chemotherapy is generally well tolerated and is an active second-line regimen against ovarian cancer.

Abstract
10526 Background: Due to high activity of taxanes (T) and anthracyclines (A) in advanced breast cancer (BC) and to the lack of cross-resistance between them, several adjuvant (adj) trials have been performed to test the efficacy of combination or sequential schedules of T and A adjuvant. In most of the sequential trials A followed T. The sequence T->A was proven active in metastatic BC, but no data are available in the adj setting. This multicenter randomized phase III study was designed to evaluate the efficacy of the sequence T->A vs an A containing regimen Methods: Pts with pT1–3 pN1 M0 (UICC1997) BC, age 18–70, PS(ECOG) 0–1, normal cardiac function, adequate bone marrow, hepatic and renal function were eligible for the study. Pts were stratified according to institution, age (≤ 50 vs > 50), hormonal receptor status and number of involved nodes (≤ 3, 4–9, ≥ 10) and were randomized to receive either 4 cycles of EC (Epirubicin 120 mg/m2 + Cyclophosphamide 600 mg/m2 on day 1 q21) in arm A or 4 cycles of D (100 mg/m2 on day 1 q21) followed by 4 cycles of EC in arm B. Primary endpoint was DFS. Secondary endpoints OS and toxicity. Results: Between april 1999 and october 2005, 750 pts were enrolled (374 in arm A and 376 in arm B) in 25 Italian institutions. Pts characteristics are as follows: Arm A: age ≤ 50 yrs 185/374; ≤ 3 nodes 182/374, 4–9 nodes 129/374, ≥ 10 nodes 63/374; positive HR 287/374 Arm B: age ≤ 50 yrs 197/376; ≤ 3 nodes 184/376, 4–9 nodes 131/376, ≥ 10 nodes 61/376; positive HR 289/376 Toxicity data (Arm A vs Arm B) of the first 495(241/254) pts are the following: Neutropenia G3 (29% vs 21.3%), neutropenia G4 (32.7% vs 48.8%), febrile neutropenia G3–4 (3.7% vs 9.5%), thrombocytopenia G3–4 (3.3% vs 1.6%), anemia G3 (0% vs 2.4%), N/V G3–4 (6.2% vs 3.1%), mucositis G3–4 (3.7% vs 3.9%), diarrhea G3–4 (0.4% vs 2.8%), peripheral neuropathy G1–3 (0% vs 9.9%), hypersensitivity reactions G3–4 (0% vs 4.3%), cardiac toxicity G3 (0.4% vs 0%) Conclusions: Treatment was generally well tollerated in both arms with a higher incidence of neutropenia, usually short lasting, in arm B. The use of prophylactic G-CSF in those patients experiencing neutropenia G3–4 may be advisable. There were no significant differences in cardiac toxicity. No significant financial relationships to disclose.

Abstract
BACKGROUND Biliary tract cancers are uncommon tumors with a poor prognosis and most patients present with invasive and inoperable disease at diagnosis. Chemotherapy represents a palliative treatment, with poor response rates and a median survival of less than 6 months. Oxaliplatin and gemcitabine have shown an interesting activity as single agents in this group of patients. PATIENTS AND METHODS We carried out a multicenter phase II study to evaluate the efficacy and safety of combined oxaliplatin and gemcitabine in locally advanced and metastatic biliary tract carcinoma. The schedule of chemotherapy included oxaliplatin 100 mg/m(2) on day 1 and gemcitabine 1000 mg/m(2) on days 1 and 8, every 21 days. RESULTS All the 24 patients were evaluable for response and toxicity. According to RECIST criteria we observed one complete response and 11 partial responses for an overall response rate of 50%. Overall survival for all the patients on study was 12 months (range 2-30). According to WHO criteria, three patients (12.5%) suffered grade 3 neutropenia and three patients (12.5%) grade 3 thrombocytopenia. Only two patients (8%) suffered grade 3 neuropathy. CONCLUSIONS Oxaliplatin and gemcitabine chemotherapy seems to be effective with a favorable safety profile in first-line chemotherapy of advanced biliary tract cancers.

Abstract
BACKGROUND The aim of the study was to evaluate the safety and efficacy of the raltitrexed/5-fluorouracil/levofolinic acid combination regimen as first-line chemotherapy for elderly patients with advanced/metastatic colorectal cancer. PATIENTS AND METHODS Previously untreated patients with metastatic colorectal cancer received raltitrexed 2 mg/m(2) i.v. plus levofolinic acid and 5-fluorouracil according to the De Gramont' schedule given every 2 weeks as first-line chemotherapy. Patients were re-evaluated after six cycles and chemotherapy was continued up to tolerance or disease progression. RESULTS Seventy patients aged >/=65 years were accrued from 11 centers between September 2001 and July 2002. According to the intention-to-treat analysis, the overall response rate was 35% (95% CI 29.5% to 40.5%) including one complete response (1%) and 24 partial responses (34%). Twenty patients (31%) showed a stabilization of disease for a tumor growth control rate of 64% (95% CI 57% to 71%). The median overall survival was 12.5 months and the median time to disease progression was 6.5 months. No toxic deaths or allergic reaction were recorded. Grade 4 toxicities were non-existent. The main hematological toxicity was grade 3 neutropenia, which occurred in 9% of patients, and grade 3 anemia in only one case, while no case of graded 3 thrombocytopenia was observed. Grade 3 non-hematological toxicities were asthenia (11%), transient increase of transaminases (10%) and diarrhea (4%). CONCLUSIONS The results of this study suggest that the raltitrexed/5-fluorouracil/levolofinic acid combination is an effective and well tolerated regimen for the treatment of elderly patients with advanced colorectal cancer. Its ease of administration and patient's tolerance warrant further investigation over 5-fluorouracil/folinic acid regimens.

Abstract
To evaluate the efficacy and toxicity of weekly docetaxel (D) as II line treatment in non-small cell lung cancer (NSCLC), in November 1999, we started a phase II study on advanced (stages IIIB-IV) NSCLC patients pre-treated with at least one platinum-based chemotherapy regimen with or without radiotherapy. The schedule consisted of D 40 mg/m(2), weekly for 6 weeks, followed by a rest period of 2 weeks, for three cycles or until progression. Eligibility criteria were: histopathologic diagnosis of NSCLC; age <or=75 years; evaluable or measurable progressive lesions; PS (ECOG) 0-2; adequate haematology and biochemistry parameters; no serious concurrent diseases; no symptomatic brain lesions; and informed consent. The end points were assessment of overall response rate, toxicity and quality of life (QoL). Patients were re-evaluated at the end of every cycle. An interim analysis of 18 patients (16 M) was performed. Weekly courses were 132; 16 of 18 patients were evaluable for response and 17 of 18 for toxicity. Two of the 16 patients (12.5%) had a partial response (95% CI: 10.5-14.7%). Haematological toxicity was very mild: grade 1-2 neutropenia occurred in four patients, grade 3 neutropenia in two patients; grade 1-2 anaemia in four patients; and grade 1-2 thrombocytopenia in two patients. Non-haematological toxicity was also very mild, with the exclusion of asthenia (grade 1-2 in ten patients and grade 3 in five patients) and alopecia (grade 1-2 in seven patients and grade 3 in eight patients). No cases of grade 4 toxicity were observed. No QoL evaluations were reported in this interim analysis. In conclusion, these preliminary data confirm that weekly D results in tolerable toxicity in pre-treated NSCLC. Myelo-suppression, the dose-limiting toxicity of every 3 week schedules, is not a clinically relevant problem when D is administered weekly. G-CSF was used only sporadically in four patients, and no febrile neutropenia was reported. Patients were pre-treated with dexamethasone and no allergic reactions were seen. Although the therapeutic activity appears to be comparable to that of every 3 week schedules, more data are necessary before definite conclusions can be drawn. Accrual of patients is still ongoing.

Microdiscectomy in the treatment of lumbar disc herniation. LA CHIRURGIA DEGLI ORGANI DI MOVIMENTO 2000; 85:337-44. [PMID: 11569358] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Subscribe] [Scholar Register] [Indexed: 02/21/2023]
Abstract
The authors report their experience with short- and medium-term microdiskectomy for the treatment of lumbar disc herniation. It is based on 760 operations performed between 1985 and July 1999: expulsed hernias and those of large size with intense pain symptoms and/or neurologic deficit were treated. During the same period of time, the authors used enzymatic and percutaneous nucleolysis according to Onik for smaller hernias. The incidence of satisfactory results was high (90.1%), in agreement with the results published in the literature. There was a low incidence of complications (4.6%), and of these 2.8% had a benign spontaneous evolution; 1% was prevented during surgery, 0.5% was prevented with subsequent surgery, while only 0.2% was the cause of definitive failure. Unsatisfactory results were constituted by the sequelae of complications (1 discitis, 4 liquoral cysts, 1 error in level not diagnosed intraoperatively), stenosis of the lateral recess not diagnosed pre- or intraoperatively, and thus not treated; in 6.1% of cases there was no plausible justification. The microsurgical technique above all reduces the duration of hospitalization (5 days on the average, but with 91% of cases dismissed on day 3), and allows for a rapid return to work activity (after 63 days for patients who are not employees, but with a return after 20 days in 95% of cases).

Abstract
The results of infection surveillance in orthopaedics are reported: the high incidence of hospital infections in patients undergoing major surgery, the paucity of microbiological data and the failure to standardise prophylaxis protocols were the most significant findings as well as providing a point of departure for programming future fields of intervention and for redefining the operating framework for continuous infection surveillance.

Abstract
Boron's low atomic number and low concentration make its measurement in hard dental tissues difficult. Using nuclear reaction, the 11B(p,alpha)8Be*, enamel, dentine and radicular cement of 18 dental elements, ten healthy and eight decayed teeth, both permanent and deciduous were studied. The highest Boron concentrations were found in the two most superficial microns of the vestibular enamel in non-decayed incisors, particularly deciduous ones. Premolar and molar teeth showed lower Boron concentrations than frontal ones, decayed teeth revealed hardly any Boron. In confirmation of the prevailing exogenous contribution of this karyostatic trace element, on average, Boron concentrations were 2.5 times as high as dentine and 10 times as high as cement.
