Abstract
When using liquid scintillator detectors to measure the neutron emission spectrum from fusion plasmas, the problem of pile-up distortion can be significant. Because of the large neutron rates encountered in many fusion experiments, some pile-up distortion can remain even after applying traditional pile-up elimination methods, which alters the shape of the measured light-yield spectrum and influences the spectroscopic analysis. Particularly, pile-up events appear as a high-energy tail in the measured light-yield spectrum, which obfuscates the contribution that supra-thermal ions make to the energy spectrum. It is important to understand the behavior of such "fast ions" in fusion plasmas, and it is hence desirable to be able to measure their contribution to the neutron spectrum as accurately as possible. This paper presents a technique for incorporating distortion from undetected pile-up events into the analysis of the light-yield spectrum, hence compensating for pile-up distortion. The spectral contribution from undetected pile-up events is determined using Monte Carlo methods and is included in the spectroscopic study as a pile-up component. The method is applied to data from an NE213 scintillator detector at JET and validated by comparing with results from the time-of-flight spectrometer TOFOR, which is not susceptible to pile-up distortion. Based on the results, we conclude that the suggested analysis method helps counteract the problem of pile-up effects and improves the possibilities for extracting accurate fast-ion information from the light-yield spectrum.

Abstract
Twelve patients with disseminated breast cancer were injected with monoclonal antibody MBr1 at the National Cancer Institute of Milan, Italy, from January 1983 to March 1985. The first seven patients had advanced disease and the remaining five operable breast cancer. In the first seven patients the initial dosage of MBr1 was 0.5 mg and was doubled in the next patient up to 16 mg. The last five women received 10 mg of MBr1. No general side effects such as broncospasm, hypotension, immediate or delayed allergic reactions were observed. Four patients who were injected with 10 mg or more experienced fever, shudder and vague abdominal and articular pain. The following tests were monitored: R.B.C., W.B.C., percentage of lymphocytes, blood glucose, urenitrogen and creatinine, serum levels of Na+, K+, Cl–, total proteins levels, albumins and globulins, bilirubin, GOT, GPT, alkaline phosphatase, LDH, amylase, γGT and CPK. No major modifications were observed: a limited increase of the transaminases, LDH and γGT was evident at the last check. An early temporary alteration of CPK was observed in the four patients who had symptoms. Serum levels of MBr1 are detectable immediately after injection starting from 4 mg, and all sera were negative 48 hours later. It is concluded that the scanty toxicity allows to continue clinical investigations to verify the linkage between MBr1 and Ca-MBr1 « in vivo » after a single injection of no more than 16 mg of the MoAb. The increase of this dosage as well as multiple injections do not seem safe at present.

Abstract
In order to optimize the scientific exploitation of JET (Joint European Torus) during the upcoming deuterium-tritium experiments, a set of diagnostic systems is being enhanced. These upgrades focus mainly on the experimental and operational conditions expected during tritium campaigns. It should be stressed that measurements relevant for burning plasmas are specifically targeted. Previously non-available capabilities, such as a current measurement system fully covering all poloidal field circuits, are described in detail. Instrument descriptions, performance prediction, testing, and initial commissioning results of these systems are presented.

Abstract
Neutron emission spectroscopy is a diagnostic technique that allows for energy measurements of neutrons born in nuclear reactions. The JET tokamak fusion experiment (Culham, UK) has a special role in this respect as advanced spectrometers for 2.5 MeV and 14 MeV neutrons have been developed here for the first time for measurements of the neutron emission spectrum from D and DT plasmas with unprecedented accuracy. Twin liquid scintillating neutron spectrometers were built and calibrated at the Physikalisch-Technische Bundesanstalt (PTB) (Braunschweig, Germany) and installed on JET in the recent years with tangential-equatorial (KM12) and vertical-radial (KM13) view lines, with the latter only recently operational. This article reports on the performance of KM12 and on the development of the data analysis methods in order to extract physics information upon D ions kinematics in JET auxiliary-heated D plasmas from 2.5 MeV neutron measurements. The comparison of these results with the correspondents from other JET neutron spectrometers is also presented: their agreement allows for JET unique capability of multi-lines of sight neutron spectroscopy and for benchmarking other 14 MeV neutron spectrometers installed on the same lines of sight in preparation for the DT experimental campaign at JET.

Abstract
From January 1987 to February 1988, 15 stage IV melanoma patients were treated with two courses of bolus injection of rIL-2 plus LAK cell infusions at the National Cancer Institute of Milan. The original treatment regimen included a first course of rIL-2 administration (400 μg/m5 bolus injection 3 times a day [TID] for 4 days) and a second course of rIL-2 administration (800 μg/m2 bolus injection TID for 7 days) separated by 4 consecutive daily leukaphereses. Autologous lymphokine activated killer (LAK) cells were reinfused into each patient on three occasions during the second period of rIL-2 administration. Due to the appearance of grade III–IV neurological, hepatic and cardiopulmonary toxicity, 7 patients discontinued dosing before the end of treatment, one patient desired to be withdrawn and one patient died from rapidly progressive disease, although complications of rIL-2 administration may have contributed to her death. Only 6 patients completed the schedule without evidence of major intolerance, even though the planned dose during the second course of rIL-2 was reduced to 400 μg/m2. The complete duration of treatment ranged from 11 to 19 days. The total dose of rIL-2 injected ranged from 12.6 to 30.4 mg. The number of infused LAK cells ranged from 15.5x109 to 60x109/patient. Two of the 14 evaluable patients showed a minor anti-tumor response. In 5 patients new metastases in other sites were documented from 2 to 5 months after completion of dosing. No apparent association was found between progression of the disease (or the appearance of new metastases) and the total dose of rIL-2 injected, the number of LAK cells administered or the number of days of treatment. By December 1988, all patients had died of their disease in a period ranging from 3 to 14 months from the last injection of rIL-2. The lack of significant clinical responses in this study and the high toxicity of this treatment lead us to conclude that at least as far as melanoma patients are concerned, adoptive immunotherapy with rIL-2 plus LAK cells (as described here) is not a justifiable treatment option unless new evidence presents itself.

Abstract
Background Early detection of nodal metastases still represents an important goal in the management of melanoma patients. A sentinel node is defined as the first colored node in the regional lymphatic basin following injection of blue dye in the site of the primary melanoma. Sentinel node biopsy may represent a feasible technique for early identification of occult disease. A therapeutic dissection is then performed only in patients with proven nodal disease, thus introducing the concept of selective dissection. Methods At the National Cancer Institute of Milan from February 1994 to October 1996, 74 patients with a melanoma of the trunk or limbs and without clinically detectable node metastases were submitted to sentinel node biopsy and eventual selective dissection. Results The sentinel node was identified in 67 patients (90%). Nodal metastases were detected in 11 patients (16%); 5 of these were identified by an intraoperative frozen section examination. In all but one case, only the sentinel node was affected at radical dissection. Incidence of positive sentinel nodes was correlated with depth of infiltration of the primary lesion. Mapped nodal basin failures were observed in 3 patients with negative sentinel node biopsy. All patients but one, presenting distant metastases, are alive at this writing and free of disease with a follow-up ranging from 2 to 34 months. Conclusions Our study adds to accumulating evidence supporting the efficacy of sentinel node biopsy in detecting occult localizations and the potential of the technique to better select the group of patients that may benefit from nodal dissection.

Abstract
One hundred and twenty-four subjects belonging to 25 families, 51 with familial malignant melanoma (FMM), and 186 subjects belonging to 41 families, 41 with sporadic malignant melanoma, were typed for the HLA A, B, C and DR loci of the HLA system. There was the same statistically significant difference in the frequency of the haplotype A9, B35, Cw4 between each group of patients and the respective healthy relatives (p = 0.01, p = 0.01 and p = 4 × 10−3, respectively). Moreover, the higher frequency of the haplotype A9, B35, Cw4 in the healthy members of the FMM families (42.46 %) compared with the healthy members of the SMM families (23.44 %) indicates that in the latter group other individuals are at risk for the disease. Furthermore, the different frequency of haplotypes B5, DR5 and B5, Cw1 suggests that differences exist between the two groups of healthy relatives. These observations confirm that the HLA region is involved in the etiology of malignant melanoma.

Abstract
To investigate possible undesirable effects due to the intravenous administration of a reagent of a xenogenic nature (monoclonal antibody 225-28S) in man, a toxicologic study was carried out on 85 patients with metastatic cutaneous melanoma. Two reagents were tested in this study: purified monoclonal antibody (MoAb) 225-28S and its F(ab')2 fragment. Purified MoAb was labelled with 131I and F(ab')2 fragment with 131I, or 123I, or 111In or 99Tc. The quantity of MoAb or F(ab')2 injected ranged from 14 to 750 μg, and the specific activity from 37.0 to 2116.4 MBq/mg. The total radioactivity injected varied from 25.9 to 891.7 MBq/mg. In addition to a careful clinical examination, the following tests were done to monitor possible adverse effects: blood glucose, azotemia, RBC, WBC, platelet count, serum creatinine, creatinine clearance, plasma electrolyte levels, serum proteins, albumin/globulin ratio, serum bilirubin, SGOT, SGPT, γGT, and CPK. These tests were done before the injection and on days 7 and 14. No patient experienced adverse general effects like fever, nausea, vomiting or allergic reactions. None of the aforementioned hematometric and biochemical tests showed significant variations compared with the initial values. It is concluded that a single injection of these reagents at the dosages tested is completely atoxic.

Abstract
Aim To evaluate the role of a surgical approach in patients affected with gastric metastases from cutaneous melanoma. Methods A retrospective review of our local melanoma database of 2100 patients identified 31 cases with gastric metastatic deposits. Nine of them were considered candidates for surgical resection. Results Median overall survival of the 9 patients who underwent surgery was 14.2 months. Six (67%) underwent a local radical resection of disease, and 3 (33%) had a simple exploratory laparotomy. The median survival was 21.6 months (range, 4-32 months) for the subset receiving radical surgery and 3.6 months (range, 2-6 months) for the patients who had no resection. Median follow-up was 14.2 months. No specific correlation of serologic LDH levels and final outcome, as documented elsewhere, was observed. A marked decreased or substantial remission of symptoms with an improvement in quality of life was observed in all radically resected patients. Conclusions Patients with gastric metastases from melanoma may benefit from surgery if all macroscopic disease can be removed. In addition, gastric resection in patients with symptomatic melanoma spread to the stomach provides important symptomatic palliation.

Abstract
Biopsy of head and neck sentinel nodes (SNs) can be technically problematic due to the unpredictable and variable drainage patterns of this anatomic region. The aim of the present study was to evaluate the feasibility of SN biopsy for cutaneous melanoma of the head and neck. We performed SN biopsy in 17 patients affected by stage I cutaneous melanoma of the head and neck on the basis of lymphoscintigraphy, blue dye and gamma probe. A total of 24 procedures were performed. Drainage to more than one lymphatic basin was observed in five patients (two basins in three cases and three basins in two cases) and in all cases SN biopsy was performed in all basins. The biopsy distribution by site was: six cervical nodes, five parotid nodes, four supraclavicular and submandibular nodes, three auricular and axillary nodes. The SN identification rate was 87.5% (21/24); metastases were discovered in four cases, with a positivity rate of 23.6%. At the time of writing, 1 patient is alive with local disease, 3 patients are dead and 13 are alive and free of disease with a follow-up ranging from 1 to 40 months (median, 21 months) following SN biopsy. In our opinion preoperative lymphoscintigraphy and the intraoperative use of a gamma probe are useful for the identification of lymphatic drainage of cutaneous melanoma of the head and neck.

Abstract
Purpose In modern management of rectal carcinoma, the preoperative evaluation of disease parameters is important for selection of therapeutic options. Such parameters are currently defined through endorectal ultrasonography or endoscopic ultrasonography. A retrospective analysis of the parameters obtained with double-contrast barium enema (DCBE) and endorectal balloon computed tomography (CT) was conducted to verify the diagnostic reliability of the radiological techniques and to establish whether there is still an indication for their use. Methods 53 consecutive patients with adenocarcinoma of the distal half of the rectal ampulla underwent double contrast barium enema examination and CT of the pelvis with endorectal balloon. On the basis of the DCBE and CT assessment we evaluated: 1) the distance between the cranial extremity of the anal canal and the distal margin of the neoplasm; 2) the radial diffusion of the tumor; 3) the metastatic involvement of the perirectal and inferior mesenteric lymph nodes. Results 1) CT and DBCE measurements of the distal margin tended to coincide, but both tended to overestimate the measurement when compared to the pathologic examination; 2) in the identification of neoplastic infiltration of perirectal fat (T3) CT had 100% sensitivity, 78.7% specificity and 86.8% accuracy; 3) the CT sensitivity for detecting lymph node metastasis was 52.6%, specificity 85.3% and accuracy 73.6%. Conclusions The diagnostic information provided by the radiological examinations is comparable to that of clinical and instrumental methods currently employed for staging of rectal carcinoma, although the latter are preferred because they are more readily accessible and less costly. DCBE and CT can therefore be usefully employed for staging of cancer of the rectum in those cases in which there are limitations of the current standard methods.

Abstract
The authors report a rare association between cutaneous melanoma and Von Recklinghausen's disease (NF-1) and analyze the possible meaning of this occurrence. Various types of tumors have been associated with NF-1, in particular those of neuroectodermal origin, such as malignant peripheral nerve sheath tumors (MPNST) and phaeochromocytoma. The development of malignant melanoma in NF-1 patients is rare. Data from the literature is enable to demonstrate an increased incidence of cutaneous melanoma in patients with neurofibromatosis but the association of these two disorders seems reasonable in theory, as both are abnormalities of a neural crest origin. The cases described may represent not only a clinical report of two rarely associated disorders, but may also confirm the biological mechanisms responsible for these infrequent diseases.

Abstract
From February 1982 to December 1983, 42 patients affected by neoplasms of the limbs were treated at the Istituto Nazionale Tumori of Milan by hyperthermic antiblastic perfusion in extracorporeal circulation at the temperature of 40-41 °C for 1 h. Thirty-two were affected by melanoma, 4 by osteogenic sarcoma, 2 by squamous-cell carcinoma, 1 by liposarcoma, 1 by hemangiopericytoma, 1 by clear-cell sarcoma and 1 by Kaposis's sarcoma. As regards the immediate response, a complete plus partial remission rate of 88 % without any major complication was obtained. The follow-up period is too short for any considerations about overall survival. However, because of these good clinical results we consider this method able to locally control the evolution of neoplasms of the extremities, allowing in many cases a limb salvage.

Abstract
Two patients with extensive squamous cell carcinoma of the lower extremities, candidate for demolitive surgery, were treated by hyperthermic antiblastic perfusion in extracorporeal circulation. The temperature reached was 41 degrees C and the drug used was methotrexate at the dosage of 500 mg. Radical excision of the ulcer was possible in the 2 patients. Both tumors underwent extensive necrosis, and histology done 1 month after perfusion on surgical specimens showed limited areas of residual malignancy. These 2 patients suggest that hyperthermic antiblastic perfusion may be a limb salvage procedure in the multimodal management of extended squamous cell carcinoma of the extremities.

Abstract
Toxicity and clinical effects of a new brand of recombinant interleukin 2 (rIL2, Bioleukin™, Biogen, Geneva) were evaluated by a phase I study in 12 patients with stage III melanoma. Escalating doses from 100 μg/m2 to 800 μg/m2 were administered thrice a day with bolus injections given via a peripheral venous catheter for up to a maximum of 7 days. All patients showed malaise, fever and chills and mild gastrointestinal side effects. A modest electrolyte imbalance (hypocalcemia and hypokalemia) was detected in all 12 patients. Renal toxicity as judged by serum creatinine was not observed, and hepatic toxicity was moderate with the possible exception of one patient who had an unclear previous history of liver dysfunction. Mild, transient leukopenia was found in several patients, whereas thrombocytopenia developed in 4 patients; no anemia was observed. Cutaneous rash was seen in half of the patients treated. Fluid retention was minimal, with a weight gain associated to treatment that never exceeded 10% of pretreatment body weight. Electrocardiographic alterations developed in 2 patients in the form of ventricular and supraventricular extrasystoles. In 2 patients given the highest dose of rIL2, a significant reduction in transfer lung factor for carbon monoxide was seen, indicating alterations in pulmonary functions. Other dose-related toxicities were thrombocytopenia and malaise. All side effects disappeared 2-3 days after the end of rIL2 administration. No major responses were seen in association with the 4-8 days of treatment given in this study.

Abstract
A prospective study to evaluate the clinical usefulness of radioimmunodetection of melanoma in clinical practice is ongoing at the National Cancer Institute of Milan, Italy. Technical conditions for the application of the method were previously reported. In this trial, 99mTc-labelled F(ab’) 2 fragments of the 225.28S monoclonal antibody were used against a high molecular weight melanoma associated antigen (HMW-MAA). Retrospective studies on radioimmunodetection of melanoma have already been made by our group and by other Centers in about 300 patients. This study concerns the evaluation of the regional extension of primary melanoma. 23 patients with 32 suspected lymphatic involvements of melanoma on the trunk and arms underwent immunoscintigraphy. No false positive results were observed; 3 false negatives, one corresponding to a micrometastasis, were noticed. Specificity corresponds to 100% and sensitivity to 78.6%.

Abstract
A cross-correlation frequency-resolved optical gating (FROG) concept, potentially suitable for characterizing few or sub-cycle pulses in a single shot, is described in which a counter-propagating transient grating is used as both the gate and the dispersive element in a FROG spectrometer. An all-reflective setup, which can operate over the whole transmission range of the nonlinear medium, within the sensitivity range of the matrix sensor, is also proposed, and proof-of-principle experiments for the ultraviolet and visible-to-near-infrared spectral ranges are reported.

Abstract
In order to complete the exploitation of the JET ITER-like Wall and to take full benefit from deuterium-tritium experiments on JET, a set of diagnostic system refurbishments or upgrades is in progress. These diagnostic enhancements focus mainly on neutron, gamma, fast ions, instabilities, and operations support. These efforts intend to provide better spatial, temporal, and energy resolution while increasing measurement coverage. Also previously non-existing capabilities, such as Doppler reflectometry is now available for scientific exploitation. Guaranteeing diagnostic reliability and consistency during the expected DT conditions is also a critical objective of the work and systems being implemented. An overview of status and scope of the ongoing projects is presented.

Abstract
A prototype Single crystal Diamond Detector (SDD) was installed at the Joint European Torus (JET) in 2013 along an oblique line of sight and demonstrated the possibility to carry out neutron spectroscopy measurements with good energy resolution and detector stability in discharges heated by neutral beam injection and radio-frequency waves. Starting from these positive results, within the Vertical Neutron Spectrometer project of the Joint European Torus, we have developed a pixelated instrument consisting of a matrix of 12 independent SDDs, called the Diamond Vertical Neutron Spectrometer (DVNS), which boosts the detection efficiency of a single SDD by an order of magnitude. In this paper we describe the main features of the DVNS, including the detector design, energy resolution, and data acquisition system for on-line processing. Preliminary spectroscopy measurements of 2.5 MeV neutrons from the present deuterium plasma at JET are finally presented.

Abstract
Background Male breast cancer is a rare malignancy. Despite the lack of prospectively generated data from trials in either the adjuvant or metastatic setting, patients are commonly treated with hormone therapies. Much controversy exists over the use of gonadotropin-releasing hormone analogues in metastatic male breast cancer patients. We conducted this study to provide more concrete ground on the use of gonadotropin-releasing hormone analogues in this setting. Methods We herein present results from a pooled analysis including 60 metastatic male breast cancer patients treated with either an aromatase inhibitor or cyproterone acetate as a monotherapy (23 patients) or combined with a gonadotropin-releasing hormone analogue (37 patients). Results Overall response rate was 43.5 % in patients treated with monotherapy and 51.3 % with combination therapy (p = 0.6). Survival outcomes favored combination therapy in terms of median progression-free survival (11.6 months versus 6 months; p = 0.05), 1-year progression-free survival rate (43.2 % versus 21.7 %; p = 0.05), median overall survival (29.7 months versus 22 months; p = 0.05), and 2-year survival rate (64.9 % versus 43.5 %; p = 0.05). Conclusions In metastatic male breast cancer patients, the combined use of gonadotropin-releasing hormone analogues and aromatase inhibitors or antiandrogens seems to be associated with greater efficacy, particularly in terms of survival outcomes, compared with monotherapy. Collectively, these results encourage considering these agents in the metastatic setting.

Abstract
Background The role of chemotherapy in the treatment of metastatic male breast cancer patients remains unknown, and the only available evidence stem from small, retrospective series evaluating outdated drugs and/or regimens. Methods In this retrospective study we evaluated the activity of polychemotherapy, consisting of three-drug (anthracycline-containing and anthracycline-free) regimens, as a first-line therapy for metastatic male breast cancer patients who had received at least one prior endocrine therapy. Results Fifty patients treated between 1978 and 2013 were included in the present analysis. Regarding best response, we recorded 1 (2%) complete response and 27 (54%) partial responses, for an overall response rate of 56% (95% CI, 42.2-69.8). Considering stable disease, the disease control rate was 84%. Median progression-free survival was 7.2 months (95% CI, 5.9-8.5), and median overall survival was 14.2 months (95% CI, 12.2-16.2). Albeit we observed some differences for all the outcomes explored when comparing anthracycline-containing and anthracycline-free regimens, they were not statistically significant. Conclusions Chemotherapy, consisting in both anthracycline-containing and anthracycline-free regimens, showed encouraging antitumor activity in metastatic male breast cancer patients previously treated with endocrine therapy.

Abstract
A noise-seeded transient comb of Raman sidebands spanning three octaves from 180 to 2400 nm, is generated by pumping a hydrogen-filled hollow-core photonic crystal fiber with 26-μJ, 300-fs pulses at 800 nm. The pump pulses are spectrally broadened by both Kerr and Raman-related self-phase modulation (SPM), and the broadening is then transferred to the Raman lines. In spite of the high intensity, and in contrast to bulk gas-cell based experiments, neither SPM broadening nor ionization are detrimental to comb formation.

Abstract
BACKGROUND The incorporation of docetaxel into the cisplatin and fluorouracil backbone has been demonstrated to be an active combination in metastatic gastric cancer. Nevertheless, this regimen is burdened by nonnegligible toxicity. We hypothesized that replacing cisplatin and fluorouracil with oxaliplatin and capecitabine should be an active and safe option for metastatic gastric cancer patients. METHODS In this phase II study, we tested the activity of docetaxel in combination with oxaliplatin and capecitabine (DOC) as a first-line treatment. DOC was administered as follows: docetaxel (60 mg/m(2)) and oxaliplatin (100 mg/m(2)) on day 1, and capecitabine (500 mg/m(2)) was administered orally twice daily given continuously, with cycles repeated every 3 weeks. The primary endpoint was the overall response rate. RESULTS Forty-eight patients entered the study. All patients had metastatic disease (stage IV). None of the patients had previously received chemotherapy for advanced disease. Performance status was 0, 1, and 2 in 25, 58, and 17 % of patients, respectively; 13 patients (27 %) had adenocarcinoma of the gastroesophageal junction, and 29 patients (60.5 %) had two or more metastatic sites. The overall response rate was 52.1 %. Progression-free survival and overall survival were 6.9 and 12.6 months, respectively. The treatment was well tolerated with no treatment-related deaths. The most common grade 3-4 toxicity was neutropenia (41 %). CONCLUSIONS DOC is an effective and tolerated first-line treatment, and the lower dose of docetaxel and oxaliplatin used in this study compared with other similar regimens does not seem to hamper the antitumor activity.

Abstract
BACKGROUND The role of second-line therapy in gastric cancer patients mostly stemmed from clinical trials with monochemotherapy carried out in Asian countries. Nevertheless, these results cannot be broadly generalized as molecular studies suggested the existence of different sets of deregulated gene networks correlated with ethnicity. In the present study, we investigated the activity and safety of FOLFIRI given as a second-line therapy in metastatic gastric or gastro-esophageal junction cancer patients who experienced disease progression on or after first-line docetaxel-containing chemotherapy. METHODS Patients with histologically confirmed metastatic gastric cancer who failed docetaxel-containing first-line therapy and who received FOLFIRI in second line were eligible for the study. Seventy patients treated at three Italian cancer centers between 2005 and 2012 entered the study. Patients received every 2 weeks irinotecan 180 mg/m2 as 1 h infusion on day 1, folinic acid 100 mg/m2 intravenously days 1-2, and fluorouracil as a 400 mg/m2 bolus and then 600 mg/m2 continuous infusion over 22 hours days 1-2. RESULTS We observed 1(1.4%) complete response, 15 (21.4%) partial response, for an overall response rate of 22.8% (95% confidence interval (CI): 13.4-32.3). Stable disease was recorded in 21 (30%) patients. Median progression-free survival and overall survival were 3.8 months (95% CI: 3.3-4.4) and 6.2 months (95% CI: 5.3-7.1), respectively. The treatment was well tolerated, as the most common G3-4 toxicities were neutropenia (28.5%) and diarrhea (14.5%). CONCLUSIONS FOLFIRI appears an effective and safe treatment option for pretreated metastatic gastric cancer patients, and deserves further investigation in randomized clinical trials.

Abstract
e15065 Background: So far, the prognosis of advanced gastric cancer is dismal. Combination chemotherapy of docetaxel (D), cisplatin (C) and fluorouracil (F) showed activity in metastatic gastric cancer, but this regimen was complicated by a high incidence of myelotoxicity. We performed a multicenter phase II trial substituting C with oxaliplatin (O) and F with capecitabine (X) in chemotherapy-naive patients (pts) with gastric or GEJ adenocarcinoma. Methods: Pts with measurable distant metastases received D 60 mg/mq iv, O 100 mg/mq iv on day 1 and X 500 mg/mq orally twice daily continuously, with cycles repeated every 3 weeks for a maximum of 8. G-CSF was used only as secondary prophylaxis. The primary endpoint was overall response rate (RR) according to RECIST. Toxicity was reported according to NCI-CTC v 3.0. Optimal Simon's two-stage design was employed with 6/15 responses required in the first stage to allow continuation to 46 pts. Results: 46 pts were enrolled: M/F 28/18; median age 66 years (32-75); median ECOG PS 1 (0-2); primary tumor resected/ unresected 16/30; disease location was gastric in 34 and GEJ in 12 pts; sites of disease were liver in 27, nodes in 25, peritoneum in 20, lung in 8 and bone in 5 pts. At the time of analysis all pts were evaluable for response and toxicity. In 46 pts, 3 CR and 21 PR were observed, for an overall RR of 52.1% (95% CI, 37.7%-66.5%). Responses were obtained in 15/27 pts (55%) with liver metastases. Disease remained stable in 14 pts (30.5 %). Median TTP was 6.8 months and median OS was 12.6 months. Grade 3/4 neutropenia, thrombocytopenia and anemia occurred in 41%, 4% and 9% of the pts, respectively. Febrile neutropenia was observed in 2 pts (4%). Other grade 3 toxicities included mucositis in 2 pts (4%), vomiting in 3 pts (6.5%) and diarrhea in 2 pt (4%). There were no severe neurotoxicity, nor treatment-related deaths. Conclusions: The DOX combination is an active and well tolerated novel chemotherapy regimen for treating metastatic gastric or GEJ adenocarcinoma and deserves further evaluation in randomized trials and, hopefully, in neoadjuvant setting.

Abstract
Pancreatic adenocarcinoma (PC) is the third most common cancer associated with BRCA mutations. Most notice has been given to BRCA2, while the association between BRCA1 and PC is less widely reported. Recently, PALB2 has been implicated in both PC and breast cancer (BC) susceptibility. We selected 29 Italian PC patients from a case-control study of PC according to their personal and family history of both PC and breast/ovarian cancer (BC/OC) and tested them for presence of germline mutations in BRCA1, BRCA2 and PALB2. We identified no germline mutations or deletions in PALB2, but detected 7 BRCA mutations (4 in BRCA1 and 3 in BRCA2). These findings suggest that PALB2 does not play a major role in PC susceptibility in our population. As we found an almost equal frequency of germline mutations in BRCA1 and BRCA2, germline alterations in either of these genes may explain a subset of Italian families presenting both PC and BC/OC. Moreover, as we began the observation of these families from probands who are affected by PC, we provide here a direct assessment of the role of PALB2 and BRCA mutations in PC susceptibility.

Abstract
AIM Laparoscopic appendectomy (LA) is not yet unanimously considered the gold standard treatment for appendicitis, despite the increasing use of advanced laparoscopic operations and the high incidence of the disease. METHOD Due to the results of an audit which classified LA as widespread in Italy, a Consensus Conference was organized, in order to give evidence-based answers to the most debated problems regarding the operation. After researching the literature, a panel of 20 experts were selected and interviewed on hot topics; a subsequent discussion using the Delphi methodology was utilized in the course of the consensus conference and submitted to the evaluation of an audience of surgeons. RESULTS Checkpoint statements were formulated whenever an agreement was reached. A level of evidence was then assigned to single statements and the process revised by two external reviewers. CONCLUSION Consensus development guidelines are herein reported and regard diagnostic pathway, diagnostic laparoscopy, indications, behaviour in case of innocent appendix, technical aspects, learning curve; however, some questions remain unsolved due to the lack of evidence.

Abstract
AIMS This study describes the experience of the National Cancer Institute of Milano in the treatment of anorectal melanoma over the last 32 years. METHODS The influence of different surgical approaches on local care and final outcome was investigated on 40 completely evaluable patients, followed for a median follow-up time of 75 months. The analysis was carried out by calculating and comparing overall survival, disease-free survival and cumulative incidence curves of disease recurrence. RESULTS Thirty-one patients underwent radical surgery: nine abdominoperineal resections, four total rectal resections and coloendoanal anastomosis, and 18 local excisions. The remaining nine patients received palliative treatments. Median overall survival time for patients receiving non-radical treatments was poor: only 6 months. However, even when a radical surgery was undergone, the prognosis of patients with anal melanoma remains dismal. Local relapse incidence was 45.8% for the limited surgery group, but non-existent for the extended-surgery group (p = 0.007). However, the median disease-free survival time was 7 and 9 months for patients receiving limited or major surgery (p = 0.97). Overall survival was 17 months, irrespective of the adopted surgery. CONCLUSION Prognosis of anal melanoma remains poor. Final outcome is not influenced by modality of surgery. A limited but radical excision can be considered whenever possible while a major demolitive surgery should be applied only for therapy of advanced or bulky lesions.

Abstract
Polyketone polymer -[-CO-CH(2)-CH(2)-](n)-, obtained by copolymerization of ethene and carbon monoxide, is utilized for immobilization of three different enzymes, one peroxidase from horseradish (HRP) and two amine oxidases, from bovine serum (BSAO) and lentil seedlings (LSAO). The easy immobilization procedure is carried out in diluted buffer, at pH 7.0 and 3 degrees C, gently mixing the proteins with the polymer. No bifunctional reagents and spacer arms are required for the immobilization, which occurs exclusively via a large number of hydrogen bonds between the carbonyl groups of the polymer and the -NH groups of the polypeptidic chain. Experiments demonstrate a high linking capacity of polymer for BSAO and an extraordinary strong linkage for LSAO. Moreover, activity measurements demonstrate that immobilized LSAO totally retains the catalytic characteristics of the free enzyme, where only a limited increase of K(M) value is observed. Finally, the HRP-activated polymer is successfully used as active packed bed of an enzymatic reactor for continuous flow conversion and flow injection analysis of hydrogen peroxide containing solutions.

Abstract
BACKGROUND Docetaxel is a new agent with activity in metastatic gastric cancer. This phase II study was designed to evaluate the activity and safety of an epirubicin, cisplatin and docetaxel combination in patients with this disease. PATIENTS AND METHODS Forty-six patients with gastric adenocarcinoma with measurable distant metastasis were eligible for the study. Patients received epirubicin 50 mg/m(2) and docetaxel 60 mg/m(2), on day 1, and cisplatin 60 mg/m(2) on day 2. Granulocyte colony-stimulating factor 300 mug/day subcutaneously was given on days 5 and 6. Cycles were repeated every 3 weeks for a maximum of eight courses. RESULTS All patients were evaluable for response and toxicity. Two complete and 21 partial responses were observed, with an overall response rate of 50% [95% confidence interval (CI) 36% to 64%]. Stable disease was observed in 13 patients (28%) and progressive disease in 10 patients (22%). The median time to progression was 6 months (95% CI 5-7) and the median overall survival was 11.2 months (95% CI 8.5-13.9). Grade 3/4 neutropenia, thrombocytopenia and anemia occurred in 46%, 7% and 13% of patients, respectively. There were five episodes of febrile neutropenia in four patients. Other grade 3 toxicities included mucositis in three patients (6.5%), vomiting in four patients (8.7%) and diarrhea in one patient (2%). There were no cardiac toxicity, severe neurotoxicity or treatment-related deaths. CONCLUSIONS The epirubicin, cisplatin and docetaxel combination is an active and well tolerated novel chemotherapy regimen for treating metastatic gastric cancer and deserves further evaluation in randomized studies.

Abstract
BACKGROUND This phase II study evaluated the efficacy and the tolerability of a sequential regimen of docetaxel followed by epirubicin-vinorelbine combination as first-line chemotherapy in advanced breast cancer. PATIENTS AND METHODS Twenty-seven patients received docetaxel 100 mg/m2 (4 cycles) followed by 4 cycles of epirubicin 90 mg/m2 (day 1) combined with vinorelbine 25 mg/m2 (days 1 and 5), with cycles repeated every 3 weeks. G-CSF was administered during epirubicin-vinorelbine treatment. RESULTS There were 1 (3.7%) CR and 14 (51.9%) PR, for an overall response rate of 55.6% (95% CI, 36.9%-74.3%). Median time to response, time to progression and overall survival were 2, 9 and 25 months, respectively. The dose-limiting toxicity was neutropenia (grade 3 to 4 in 85% of the patients). There was one toxic death due to neutropenic fever. Gastrointestinal side-effects were generally mild According to the Simon two-stage design the response rate was considered unsatisfactory and patient accrual was terminated. CONCLUSION This sequential regimen appears to be moderately effective; possibly, a modulation of the treatment based on objective responses instead of a fixed number of cycles may be more appropriate in order to obtain better results.

Abstract
The polyamines spermine, spermidine and putrescine are ubiquitous cell components. If they accumulate excessively within the cells, due either to very high extracellular concentrations or to deregulation of the systems which control polyamine homeostasis, they can induce toxic effects. These molecules are substrates of a class of enzymes that includes monoamine oxidases, diamine oxidases, polyamine oxidases and copper containing amine oxidases. Polyamine concentrations are high in growing tissues such as tumors. Amine oxidases are important because they contribute to regulate levels of mono- and polyamines. These enzymes catalyze the oxidative deamination of biogenic amines and polyamines to generate the reaction products H2O2 and aldehyde(s) that are able to induce cell death in several cultured human tumor cell lines. H2O2 generated by the oxidation reaction is able to cross the inner membrane of mitochondria and directly interact with endogenous molecules and structures, inducing an intense oxidative stress. Since amine oxidases are involved in many crucial physiopathological processes, investigations on their involvement in human diseases offer great opportunities to enter novel classes of therapeutic agents.

Abstract
ALTEA-MICE will supplement the ALTEA project on astronauts and provide information on the functional visual impairment possibly induced by heavy ions during prolonged operations in microgravity. Goals of ALTEA-MICE are: (1) to investigate the effects of heavy ions on the visual system of normal and mutant mice with retinal defects; (2) to define reliable experimental conditions for space research; and (3) to develop animal models to study the physiological consequences of space travels on humans. Remotely controlled mouse setup, applied electrophysiological recording methods, remote particle monitoring, and experimental procedures were developed and tested. The project has proved feasible under laboratory-controlled conditions comparable in important aspects to those of astronauts' exposure to particle in space. Experiments are performed at the Brookhaven National Laboratories [BNL] (Upton, NY, USA) and the Gesellschaft für Schwerionenforschung mbH [GSI]/Biophysik (Darmstadt, FRG) to identify possible electrophysiological changes and/or activation of protective mechanisms in response to pulsed radiation. Offline data analyses are in progress and observations are still anecdotal. Electrophysiological changes after pulsed radiation are within the limits of spontaneous variability under anesthesia, with only indirect evidence of possible retinal/cortical responses. Immunostaining showed changes (e.g. increased expression of FGF2 protein in the outer nuclear layer) suggesting a retinal stress reaction to high-energy particles of potential relevance in space.

Abstract
The ALTEA project investigates the risks of functional brain damage induced by particle radiation in space. A modular facility (the ALTEA facility) is being implemented and will be operated in the International Space Station (ISS) to record electrophysiological and behavioral descriptors of brain function and to monitor their time dynamics and correlation with particles and space environment. The focus of the program will be on abnormal visual perceptions (often reported as "light flashes" by astronauts) and the impact on retinal and brain visual structures of particle in microgravity conditions. The facility will be made available to the international scientific community for human neurophysiological, electrophysiological and psychophysics experiments, studies on particle fluxes, and dosimetry. A precursor of ALTEA (the 'Alteino' project) helps set the experimental baseline for the ALTEA experiments, while providing novel information on the radiation environment onboard the ISS and on the brain electrophysiology of the astronauts during orbital flights. Alteino was flown to the ISS on the Soyuz TM34 as part of mission Marco Polo. Controlled ground experiments using mice and accelerator beams complete the experimental strategy of ALTEA. We present here the status of progress of the ALTEA project and preliminary results of the Alteino study on brain dynamics, particle fluxes and abnormal visual perceptions.

Abstract
Hyperphenylalaninemia (HPA), due to a deficiency of phenylalanine hydroxylase (PAH) enzyme, is caused by mutations in the PAH gene. Molecular analysis in 23 Italian patients with PAH deficiency identified two novel (P281R, L287V) and 20 previously described genetic lesions in the PAH gene. The detection of the A403V amino acid substitution in combination with null mutations in patients with BH4-responsive PAH deficiency leads us to correlate it with BH4 responsiveness.

Abstract
UNLABELLED This study evaluated the role of (99m)Tc-sestamibi washout in the prediction of pathologic tumor response to neoadjuvant chemotherapy in 30 patients with locally advanced breast cancer. METHODS Two (99m)Tc-sestamibi studies were performed before and after chemotherapy for each patient. Early (10 min) and delayed (240 min) planar breast views were acquired after a 740-MBq (99m)Tc-sestamibi intravenous injection, and the washout rate (WOR) was computed. All patients underwent radical mastectomy with pathologic evaluation of the residual tumor size. RESULTS The pretherapy (99m)Tc-sestamibi WOR ranged from 14% to 92% (mean +/- SD, 50% +/- 18%). At pathologic examination, 15 patients showed no tumor response to chemotherapy and 15 patients showed an objective response to chemotherapy. The pretherapy (99m)Tc-sestamibi study predicted chemoresistance (WOR > 45%) in 18 of 30 patients and no chemoresistance (WOR < or = 45%) in 12 of 30 patients. When the WOR cutoff was set at >45%, the prognostic performance of the test was indicated by a sensitivity of 100%; a specificity of 80%; positive and negative predictive values of 83% and 100%, respectively; and a likelihood ratio of 5. The repeatability of the test was good, with 80%-93% interreader agreement (kappa = 0.57-0.85). Posttherapy (99m)Tc-sestamibi studies confirmed the pretherapy study prediction in 29 of 30 patients. CONCLUSION (99m)Tc-Sestamibi WOR is a reliable test for predicting tumor response to neoadjuvant chemotherapy. In fact, negative findings (WOR < or = 45%) rule out chemoresistance and positive findings (WOR > 45%) indicate a high risk of chemoresistance.

Abstract
PURPOSE This phase II multicenter trial was aimed at investigating the activity of epirubicin-vinorelbine combination as first-line chemotherapy in metastatic breast cancer patients. PATIENTS AND METHODS Ninety-seven patients with metastatic breast cancer and no prior exposure to anthracyclines received the following regimen: epirubicin 100 mg/m(2) by intravenous (IV) bolus infusion on day 1 plus vinorelbine 25 mg/m(2) by 30-minute IV infusion on days 1 and 5, every 3 weeks for up to eight cycles. All patients also received granulocyte colony-stimulating factor (G- CSF) on days 7 to 12 of every cycle. RESULTS Objective responses, confirmed at least 4 weeks after the first documentation, were observed in 65 out of 92 assessable patients (70.6%; 95% CI, 62% to 80%). Disease remained stable in 17 patients (18.5%). Responses were observed in all disease sites, being 94% in soft tissue, 60% in bone, and 66% in visceral disease. Median time to response, median duration of response, median time to progression, and median overall survival were 2, 9, 10, and 26 months, respectively. The dose-limiting toxicity was neutropenia, which was grade 4 in 36% of the patients, and was accompanied by fever in 26% of the cases. Grade 3 to 4 mucositis was encountered in 28% of the patients. Other toxicities were mild to moderate. No cardiotoxicity was observed. CONCLUSION The epirubicin-vinorelbine combination with G-CSF support has been shown in this study to be highly active as first-line treatment of metastatic breast cancer patients, with significant although transient toxicity. This justifies further evaluation in the neoadjuvant setting and in early-stage breast cancer.

Abstract
From January 1993 to May 2000, 1062 patients with primary cutaneous melanoma and no evidence of clinically detectable regional node metastases underwent sentinel node (SN) dissection to microscopically define the tumor status of the regional lymph nodes. A total of 1165 biopsies were performed. The SN identification rate was 89.6%. In 62.2% of the cases, only one SN was detected; 26.4% of patients had two SNs; and 11.4% had three or more SNs. Analysis of survival indicated that the tumor status of the nodes was the most important prognostic factor. Breslow's thickness had a significant impact on survival in tumors 4 mm or thicker, and ulceration dropped to a borderline-significant P value. To assess the tumor burden in positive SNs, all slides for patients at the Istituto Nazionale Tumori and S. Pio X Hospital were reviewed. Of 658 patients in this series, 90 had positive SNs. Eighteen of these patients had evidence of metastasis in other nodes. Of the remaining 72 with a single tumor-involved SN, 62% had a single metastatic deposit. Preliminary data from this study indicate that several subgroups may be identified among patients with positive nodes, but adequate analysis of survival requires a larger number of patients and a multicenter study.

Abstract
BACKGROUND Less than half of patients with melanoma that has spread to local draining regional lymph nodes (stage III melanoma) live with no disease for 5 years or longer after surgery. We aimed to see whether interferon alpha-2a increased survival prospects in these patients. METHODS 444 patients from 23 centres in the WHO Melanoma Programme had complete lymphadenectomy for pathologically proven regional nodal spread of melanoma and were randomly assigned to receive either 3 MU subcutaneously of recombinant interferon alpha-2a three times a week for 3 years, or to observation alone after surgery. Patients were stratified by centre, nodes with macroscopic or microscopic melanoma, number of affected nodes, and nodal metastatic spread. Treatment was continued for 3 years or until first sign of relapse. FINDINGS 424 patients entered the study. 5-year disease-free survival of those who had surgery plus interferon alpha-2a was 27.5% (95% CI 21.7-33.6); for those who received surgery alone, survival was 28.4% (22.5-34.6) (p=0.50). Neither Kaplan-Meier cumulative survival rates, nor multivariate analysis of survival, showed a difference between those who had surgery and interferon alpha-2a (35%, 95% CI 29-42) and those who had surgery alone (37%, 31-44). INTERPRETATION Patients with melanoma that has spread to the local draining regional lymph nodes tolerate well 3 MU of interferon alpha-2a given subcutaneously three times a week for 3 years, but this treatment does not improve either disease-free or overall survival.
