Abstract
Abstract
Study question
What is the destination of supernumerary embryos after a positive pregnancy test?
Summary answer
Half of the surplus cryopreserved embryos in assisted reproduction treatments are not transferred.
What is known already
Many of the surpernumerary cryopreserved embryos in assisted reproductive technologies are not transferred. This is a constant issue in many fertility centers around the world. Our objective was to report what happens with vitried surplus embryos after IVF in patients with a positive pregnancy test, carrying out an analysis according to age and final evolution of the pregnancy.
Study design, size, duration
This is a retrospective descriptive study. We analyzed 245 embryo transfer cycles, performed between January 2013 to December 2017, in 235 patients with a positive pregnancy test and who vitrified surplus embryos.
Participants/materials, setting, methods
All the patients underwent treatment with their own oocytes. The variables studied were: age, miscarriage rate (MR) and live birth rate (LBR). We compared the destination of the cryopreserved embryos according to the patient’s age and pregnancy evolution. Statistical analysis was performed with Fisher’s exact test.
Main results and the role of chance
20% of the IVF cycles (n = 49) were performed in women older than 40 years, 42% between 35 and 39 (n = 103) and 38% in women younger than 35 (n = 94). Average age was 35.8 ± 4.1 years. 859 embryos were cryopreserved (3.5 ± 1.9 cryopreserved embryos/patient). Average search time for surplus embryos was 20.5 ± 17.9 months, rising to 36.9 ± 14.9 months after delivery and decreasing to 8.7 ± 7.8 months after miscarriage (P < 0.0001). Up to date there are 118 (48.2%) patients whose cryopreserved embryos have not been transferred yet. Signficant differences were found in the three groups in using the cryopreserved embryos according to whether or not they had delivery. Almost half of the surplus cryopreserved embryos are not transferred. Regardless of the age of the patient, all groups showed the same behavior regarding the utilization of the cryopreserved embryos after delivery. It is essential to advise couples who perform assisted reproductive technologies, with a good probability of success (regardless of the patient’s age), about the responsibility that embryonic cryopreservation entails. Argentine legislation has limitations regarding the availability of cryopreserved surplus embryos.
Limitations, reasons for caution
This is a retrospective study.
Wider implications of the findings: We believe that Public Health policies related to this issue should be re evaluated based on these results.

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
Solid particles adsorbed at fluid interfaces are crucial for the mechanical stability of Pickering emulsions. The key parameter which determines the kinetic and thermodynamic properties of these colloids is the particle contact angle, θ. Several methods have recently been developed to measure the contact angle of individual particles adsorbed at liquid-liquid interfaces, as morphological and chemical heterogeneities at the particle surface can significantly affect θ. However, none of these techniques enables the simultaneous visualization of the nanoparticles and the reconstruction of the fluid interface to which they are adsorbed, in situ. To tackle this challenge, we utilize a newly developed super-resolution microscopy method, called iPAINT, which exploits non-covalent and continuous labelling of interfaces with photo-activatable fluorescent probes. Herewith, we resolve with nanometer accuracy both the position of individual nanoparticles at a water-octanol interface and the location of the interface itself. First, we determine single particle contact angles for both hydrophobic and hydrophilic spherical colloids. These experiments reveal a non-negligible dependence of θ on particle size, from which we infer an effective line tension, τ. Next, we image elliptical particles at a water-decane interface, showing that the corresponding interfacial deformations can be clearly captured by iPAINT microscopy.

Abstract
Microgels are solvent-swollen nano- and microparticles that show prevalent colloidal-like behavior despite their polymeric nature. Here we study ultra-low crosslinked poly(N-isopropylacrylamide) microgels (ULC), which can behave like colloids or flexible polymers depending on dimensionality, compression or other external stimuli. Small-angle neutron scattering shows that the structure of the ULC microgels in bulk aqueous solution is characterized by a density profile that decays smoothly from the center to a fuzzy surface. Their phase behavior and rheological properties are those of soft colloids. However, when these microgels are confined at an oil-water interface, their behavior resembles that of flexible macromolecules. Once monolayers of ultra-low crosslinked microgels are compressed, deposited on solid substrate and studied with atomic-force microscopy, a concentration-dependent topography is observed. Depending on the compression, these microgels can behave as flexible polymers, covering the substrate with a uniform film, or as colloidal microgels leading to a monolayer of particles.

Abstract
Aim The North Milan Group presents the results of a phase II study on a cisplatin-vinorelbine combination schedule in the treatment of locally advanced non-small cell lung cancer to evaluate its activity and tolerability. Methods Seventy-six consecutive patients entered the study. Patients’ characteristics were the following: males/females 69/7; median age, 61.4 years (range, 40-73); ECOG performance status, 0-1; 17 stage IIIa and 59 stage IIIb. There were 49 squamous cell carcinomas, 20 adenocarcinomas, and 7 large cell carcinomas. All patients had not been previously treated and showed measurable disease. Treatment consisted of vinorelbine, 25 mg/m2 on days 1 and 8, plus cisplatin, 80 mg/m2 on day 1, administered intravenously every 21 days for three standard courses. Results Seventy-four patients were evaluable for response. Objective responses were documented in 42/74 patients with an overall response rate (CR+PR) of 56.7%; 18/74 patients (24.3%) showed stable disease and the remaining 14/74 (18.9%) went into progression. Twelve patients (16.2%) were suitable for a subsequent surgery. The median duration of response was 13.3 months. Survival time ranged from 4 to 36 months: it was 14.6 months for PR patients, 8.6 months for NC and 5 months for PD. Mean survival time is presently 12.85 months (SE, 1.2 months). Toxicity evaluated on 222 cycles administered was acceptable, and it was necessary to use G-CSF or delay the treatment because of severe leukopenia in only a few cases. Conclusions The regimen is active and safe: the slight survival increase is likely due to the small amenability to surgery achieved (16.2%). However, our results are fully comparable to others obtained with vinorelbine in two/three drug combination chemotherapy regimens.

Abstract
A total of 1095 patients with operable breast cancer and en-rolled in a randomized clinical trial were analysed for estrogen (ER) and progesterone (PgR) receptor content of their primary tumor, and the relationships between steroid receptor status and several epidemiologic characteristics were studied. The proportion of ER+ and median ER levels increased with age: compared to women younger than 40, those aged 66 or more were approximately three times more likely to have an ER+ tumor (OR = 3.0, 95% C.I. = 1.6–5.7). This difference tended to be more marked after comparison between patients with ER > 100 fmol/mg protein and ER- within the same age groups: OR = 7.04, 95 % C.I. = 2.89–17.12. No association emerged between age and PgR. ER status and concentrations were independent of menopausal status after adjustment for age, whereas the proportion of PgR+ and PgR levels were significantly lower in postmenopausal patients of the same age. The distribution of ER and PgR profiles was similar in relation to family history of breast cancer, reproductive events and other selected epidemiologic characteristics of the patients.

Abstract
The quality of diagnostic and therapeutic care was examined in a series of 380 consecutive newly diagnosed cases of primary lung cancer seen in 20 Italian general hospitals between January and June 1987. At diagnosis most patients (78%) had one or more symptoms related to the tumor, and in an additional 9 % symptoms were related to the presence of distant metastases. The median diagnostic time lag between first symptoms and final diagnosis was 50 days with a significantly longer delay in patients first seen by their general practitioner compared with those who sought first care in hospital outpatient departments. The diagnostic process was satisfactorily carried out in fewer than two-thirds of the patients leading to complete ascertainment of disease stage and histology in 58% cases with significantly better performance in more specialized institutions. Analysis of the first-line treatment profile indicated a rather aggressive therapeutic attitude In the case of patients with non-small cell lung cancer – 28% of them had chemotherapy despite the lack of any proof of efficacy in controlled clinical trials – and a failure to identify among the patients with small cell disease those amenable to more aggressive treatment. The lack of progress in the treatment of lung cancer over the last decades seems to have resulted in widely varying practice patterns where a mixture of aggressive and laissez-faire attitudes does not take into account that in the absence of effective therapies a more conservative attitude would at least have some advantage in terms of quality of remaining life for many patients.

Abstract
Soft hydrogel particles show a rich structural and mechanical behaviour compared to hard particles, both in bulk and when confined in two dimensions at a fluid interface. Moreover, encapsulation into hydrogel shells makes it possible to transfer the tunability of soft steric interactions to hard nanoparticle cores, which bear interest for applications, e.g. in terms of optical, magnetic and reinforcement properties. In this work, we investigate the microstructures formed by hard core-soft shell particles at liquid-liquid interfaces upon compression. We produced model particles with the same silica core and systematically varied the shell-to-core ratio by synthesising shells with three different thicknesses. These particles were spread at an oil-water interface in a Langmuir-Blodgett trough and continuously transferred onto a solid support during compression. The transferred microstructures were analysed by atomic force and scanning electron microscopy. Quantitative image analysis provided information on the particle packing density, the inter-particle distance, and the degree of order of the monolayers. We discovered several essential differences compared to purely soft hydrogel particles, which shed light on the role played by the hard cores in the assembly and compression of these composite monolayers.

Abstract
BACKGROUND Fractures of the mandible are the commonest facial fractures and various treatment modalities exist like wire osteosynthesis and the use of miniplates and screw with most of the industrially developed world leaning towards the use of miniplates in the treatment of these fractures. The use has however been limited in developing countries (including Nigeria) mostly due to the cost of the plates and screws. AIM AND OBJECTIVES To identify the versatility of miniplates in the treatment of mandibular fractures at a tertiary care centre in a developing country. METHODS All Subjects aged 16 years and above in whom mandibular fractures were diagnosed were recruited over a two year period. Patients were treated under general anesthesia using either the miniplates and screws or wire osteosynthesis while some patients had both miniplates and maxillo-maxillary fixation. RESULTS A total of 94 patients were recruited for the study of which 89.4% were males while the age group 16 to 25 years constituted the majority. Though 29.8% of the study population was involved in business, only 9.6 % were professional motorcyclists. Motorcycle-related road traffic crashes constituted the commonest aetiologic agent with 41.5%, while combination fractures were the commonest fracture types seen in 54.3% of the study participants. Of the 94 patients, 77.7% had treatment of mandibular fractures by open reduction and immobilization with mini plates, while 7.4% had mini plates with Maxillo-maxillary fixation and 14.9% had wire osteosynthesis only. The site of fracture was significantly associated with the treatment modality (p= 0.02). CONCLUSION This study showed that the choice of fixation appliances in mandibular fractures was influenced by the number of fractures and the multiplicity of fracture sites. Miniplates offered functionally stable fixation with minimum complications.

Abstract
BACKGROUND Frenkel's ambulatory activity has been routinely employed by physiotherapists for rehabilitation of gait coordination, however, its immediate influence on blood pressure and heart rate has not been investigated. OBJECTIVE To investigate the acute effect of Frenkel's ambulatory activity on blood pressure and heart rate of chronic hemiparetic stroke survivors. METHOD Using a comparative study design, 60 chronic hemiparetic stroke survivors of varying onset of stroke, ≤6, >6-11 and ≥12 months were subjected to a 2-minute Frenkel's ambulatory activity on marked footsteps (from standard adult described footsteps). Participants were assessed for both blood pressure and heart rate before and after the Frenkel's ambulatory activity. RESULTS Blood pressure and heart rate significantly increased (p<0.05) following Frenkel's ambulatory activity in all the 3 categories of stroke onset above baseline. However, there was no significant difference (p>0.05) across the onsets in both blood pressure and heart rate responses. CONCLUSION The outcome of this study indicated that Frenkel's ambulatory activity has the propensity to increase blood pressure and heart rate of hemiparetic stroke survivors irrespective of the onset of stroke. We recommend a pre, within and post-activity monitoring of stroke survivors while subjecting them to Frenkel's ambulatory activity.

Abstract
In this work we present a rapid and parallel process for the fabrication of large scale arrays of electrically driven nanopillars for THz quantum cascade active media. We demonstrate electrical injection of pillars of 200 nm diameter and 2 µm height, over a surface of 1 mm(2). THz electroluminescence from the nanopillars is reported. This result is a promising step toward the realization of zero-dimensional structure for terahertz quantum cascade lasers.

Abstract
We report experiments on hard-sphere colloidal glasses that show a type of shear banding hitherto unobserved in soft glasses. We present a scenario that relates this to an instability due to shear-concentration coupling, a mechanism previously thought unimportant in these materials. Below a characteristic shear rate γ(c) we observe increasingly nonlinear and localized velocity profiles. We attribute this to very slight concentration gradients in the unstable flow regime. A simple model accounts for both the observed increase of γ(c) with concentration, and the fluctuations in the flow.

Abstract
9620 Background: We have recently shown non-inferiority in preventing acute and delayed nausea and vomiting associated with MEC between the PALO plus 1-day DEX and PALO plus 3-day DEX regimens. Planned analysis stratified by type of chemotherapy (anthracycline + cyclophosphamide [AC] group or patients receiving at least one moderately emetogenic agent according to modified Hesketh classification) has been performed. Methods: A total of 332 chemo-naïve patients with solid tumors were randomized to receive a single IV dose of PALO 0.25 mg plus DEX 8 mg IV on day 1 of chemotherapy (arm A; n=166) or the same regimen followed by DEX 8 mg orally on days 2 and 3 (arm B; n=166). Endpoints included complete response rates (CR: no emetic episodes [EE], no rescue antiemetics; primary endpoint) and proportion of patients with no EE throughout the 5 days after the first cycle of chemotherapy. Subgroups were analyzed by two-sided chi-square test. Results: Per-protocol population included 324 patients (65% women; median age 57.5 years); 35% received AC regimens, and 65% other MEC regimens. There were no significant differences between arms in CR rates according to the type of chemotherapy: 1) CR rates on AC regimens (arm A, 55.8% versus arm B, 60.7%; p=0.599); and 2) CR rates on other MEC regimens (arm A, 68.5% versus arm B, 72%; p=0.576). No significant differences between arms were also observed in the rates of patients with no EE: 1) emesis-free patients on AC regimens (arm A, 78.8% versus arm B, 73.8%; p=0.528); 2) emesis-free patients on other MEC regimens (arm A, 83.8% versus arm B, 90%; p=0.184); 3) nausea-free patients on AC regimens (arm A, 38.5% versus arm B, 44.3%; p=0.533); and 4) nausea-free patients on other MEC regimens (arm A, 58.6% versus arm B, 64%; p=0.418). Conclusions: The single-day regimen of PALO and DEX can provide effective protection against acute and delayed emesis from AC- and MEC-based regimens while avoiding to unnecessarily prolong treatment with DEX. No significant financial relationships to disclose.

Abstract
We study the flow of concentrated hard-sphere colloidal suspensions along smooth, nonstick walls using cone-plate rheometry and simultaneous confocal microscopy. In the glass regime, the global flow shows a transition from Herschel-Bulkley behavior at large shear rate to a characteristic Bingham slip response at small rates, absent for ergodic colloidal fluids. Imaging reveals both the "solid" microstructure during full slip and the local nature of the "slip to shear" transition. Both the local and global flow are described by a phenomenological model, and the associated Bingham slip parameters exhibit characteristic scaling with size and concentration of the hard spheres.

Abstract
We explored the efficacy of the IGEV regimen (ifosfamide, gemcitabine, vinorelbine and prednisone) combined with a fixed dose of lenograstim (263 mug/day) to mobilize peripheral blood stem cells (PBSCs) in 90 Hodgkin's lymphoma patients. The median total CD34+ cells/mul peak, colony-forming units granulocyte-macrophage and white blood cells for all individual collection sets were 85/mul, 12 x 10(4)/kg and 20 700/mul, respectively. An adequate number of CD34+ cells (more than 3 x 10(6) or 6 x 10(6) CD34+ cells/kg depending on whether single or tandem high-dose chemotherapy was used) were collected in 89 out of 90 (98.7%) mobilized patients, whereas the only failure reached 2.3 x 10(6) CD34+ cells/kg. The median CD34+ cell collections were 11 x 10(6)/kg (range 2.3-39 x 10(6)/kg) and 10 x 10(6)/kg (range 6-22.0 x 10(6)/kg) with a median of 1 and 2 leukaphereses for patients eligible for single high-dose treatment and for candidates for tandem transplant, respectively. Target yields were reached in 71.43 and 49.09% and additionally in 17.14 and 43.64% of cases after the first and second apheresis procedures, respectively. Hematological and non-hematological side effects were acceptable, and no toxic deaths occurred. Thirty-four patients received a single and 47 received tandem transplantation with rapid engraftment. These results confirm that the IGEV regimen with lenograstim support can be used successfully and safely to mobilize PBSCs.

Abstract
BACKGROUND Many patients with advanced non-small-cell lung cancer (NSCLC) do not tolerate cisplatin-based regimens because of its nonhemathological toxicity. PATIENTS AND METHODS We evaluated the response rate safety of new platinum analogue regimens, randomizing 147 patients with nonoperable IIIB/IV NSCLC to (i) carboplatin (area under the curve = 5 mg min/ml) on day 1 plus gemcitabine (GEM) (1000 mg/m(2)) on days 1 and 8 for six cycles; (ii) same regimen for three cycles followed by docetaxel (Taxotere) (40 mg/m(2)) on days 1 and 8 plus GEM (1250 mg/m(2)) on days 1 and 8 for three cycles; (iii) oxaliplatin (130 mg/m(2)) on day 1 plus GEM (1250 mg/m(2)) on days 1 and 8 for six cycles. RESULTS Intention-to-treat objective response rates were 25%, 25% and 30.6% in arms A, B and C, respectively. Median survival was 11.9, 9.2 and 11.3 months in arms A, B and C, respectively. Grade 3/4 neutropenia/anemia occurred in 29%/12.5%, 10%/16.5% and 8%/6% of arms A, B and C, respectively; grade 3/4 thrombocytopenia in 20.5%, 16.5% and 6%; grade 1/2 neurological toxicity in 43% of arm C. CONCLUSIONS Oxaliplatin/GEM (arm C) had similar activity to carboplatin/GEM (arm A), but milder hematological toxicity and may be worth testing in a phase III study against carboplatin/GEM in patients not suitable for cisplatin. The sequential regimen gave no additional benefit.

Abstract
This randomised phase II study evaluates the safety and efficacy profile of uracil/tegafur/leucovorin combined with irinotecan (TEGAFIRI) or with oxaliplatin (TEGAFOX). One hundred and forty-three patients with measurable, non-resectable metastatic colorectal cancer were randomised in a multicentre study to receive TEGAFIRI (UFT 250 mg m−2 day days 1–14, LV 90 mg day days 1–14, irinotecan 240 mg m−2 day 1; q21) or TEGAFOX (UFT 250 mg m−2 day days 1–14, LV 90 mg day days 1–14, oxaliplatin 120 mg m−2 day 1; q21). Among 143 randomised patients, 141 were analysed (68 received TEGAFIRI and 73 TEGAFOX). The main characteristics of the two arms were well balanced. The most common grade 3–4 treatment-related adverse events were neutropenia (13% of cases with TEGAFIRI; 1% in the TEGAFOX group). Diarrhoea was prevalent in the TEGAFIRI arm (16%) vs TEGAFOX (4%). Six complete remission (CR) and 19 partial remission (PR) were recorded in the TEGAFIRI arm (odds ratio (OR): 41.7; 95% confidence limit (CL), 29.1–55.1%), and six CR and 22 PR were recorded in the TEGAFOX group, (OR: 38.9; 95% CL, 27.6–51.1). At a median time follow-up of 17 months (intequartile (IQ) range 12–23), a median survival probability of 20 and 19 months was obtained in the TEGAFIRI and TEGAFOX groups, respectively. Median time to progression was 8 months for both groups. TEGAFIRI and TEGAFOX are both effective and tolerable first-line therapies in MCRC patients. The employment of UFT/LV given in doublet combination is interesting and the presented data appear comparable to equivalent infusion regimens described in the literature. The safety profile of the two combinations also allows an evaluation with other biological agents such as monoclonal antibodies.

Abstract
BACKGROUND Recent guidelines do not recommend antithrombotic prophylaxis (AP) to prevent catheter-related thrombosis in cancer patients with a central line. PATIENTS AND METHODS This study assessed the management of central lines in cancer patients, current attitude towards AP, catheter-related and systemic venous thromboses, and survival. RESULTS Of 1410 patients enrolled, 1390 were seen at least once in the 6-month median follow-up. Continuous AP, mainly low-dose warfarin, was given to 451 (32.4%); they were older, with a more frequent history of venous thromboembolism (VTE), and more advanced cancer. There was no difference in catheter-related thrombosis in patients given AP or not (2.8% and 2.2%, odds ratio 1.29, 95% confidence interval 0.64-2.6). The median time to first catheter-related complication was 120 days. Systemic VTE including deep and superficial thromboses and pulmonary embolism, were less frequent with AP (4% versus 8.2%, P = 0.005). Mortality was also lower (25% versus 44%, P = 0.0001). Multiple logistic regression analysis found only advanced cancer and no AP significantly associated with mortality. No major bleeding was recorded with AP. CONCLUSIONS Current AP schedules do not appear to prevent catheter-related thrombosis. Systemic VTE and mortality, however, appeared lower after prophylaxis.

Abstract
7089 Background: Trials testing chemotherapy for elderly pts with SCLC are scanty. Gemcitabine (Gem) is active and well tolerated. The G-STEP program looked for optimal 2-drug combination of G with either vinorelbine (Vin), etoposide (Eto), cisplatin (Cis), or carboplatin (Car). Methods: Extended stage SCLC pts, aged >70 years, PS 0–2, were eligible. Dose of G was 1,000 mg/m2, dd 1&8, every 3 weeks in all the four combinations. As safety data in the elderly were already available for Gem+Vin (Vin dose 25 mg/m2, dd 1&8), a two-stage minimax flexible design was applied with response as end-point: ≥13 responses/30 pts required at 1st stage, with p0=0.40, p1=0.60, α and β=0.10. For Gem+Car, Gem+Cis, Gem+Eto a phase 1–2 Bayesian design to select optimal dose was applied (Thall & Russell, Biometrics, 1998), with 3 possible outcomes for each patient: “active” (response and no unacceptable toxicity [UT]), “inactive” (no response, no UT), or “toxic” (UT independently of response). A response rate [RR] ≥60% and a rate of UT ≤25% were acceptable. Dose levels to explore were: Car: AUC 3.5 / 4 / 4.5, d1; Cis: 50 / 60 / 70 mg/m2, d1; Eto: 60 / 70 / 80 mg/m2, dd 1,2,3. Results: From May 2000 to September 2005, 78 eligible pts were enrolled; median age was 74 years (42% of pts older than 75yrs). In the whole group, median progression-free survival and overall survival were 20.3 weeks (95% CI 17.6 - 24.1) and 33.7 weeks (95% CI 23.7 - 41.6), respectively. Study of Gem+Vin was closed for inactivity after 1st stage with 11 responses / 30 pts (RR 36.7%, 95% exact CI: 19.9–56.1). Gem+Eto arm was closed after 10 pts (5 inactive and 5 toxic) because too high probability (0.994) of inactivity. Gem+Cis arm was closed after 12 pts (2 active, 5 inactive, 5 toxic) because too high probability (0.988) of inactivity. With Gem+Car (December 2005: 2 pts ongoing, 24 analysed: 12 active, 6, inactive and 6 toxic), RR in the 20 pts receiving Car at AUC 3.5 was 60% (95% exact CI: 36.1–80.9). Conclusions: The combination of gemcitabine and carboplatin seems promising for future trials in elderly patients with extended SCLC. The G-STEP program was supported by GIOGER.

Abstract
8596 Background: Recent guidelines do recommend against antithrombotic prophylaxis in cancer pts having placed a central line to prevent catheter-related thrombosis. Methods: The present study, which was an observational and prospective one, involved 18 centres in Lombardia (Italy) to assess the management of CVD in pts affected by solid or haematological tumors to evaluate in the current practice the attitude to employ the AP and the clinical evolution as regard to the occurrence of catheter-related and systemic venous thromboses and survival. Results: 1,418 pts entered the study and were followed-up during a median period of 6 months for a total of 24,182 patients-months. Subjects receiving a continuous AP, mainly with mini-warfarin according to Levine, were 439 (31.6%): they were significantly older, with a more frequent history of Venous Thromboembolism (VTE), and with a cancer in a more advanced stage. A trend in favour of those not treated with AP was noticed as regard to catheter-related thrombosis, 3.2 % vs 1.5%, (p=0.058). The median time to the first catheter-related complication was 120 days. The frequency of systemic VTE including deep and superficial vein thromboses in sites other than the venous axis where the CVD had been placed and pulmonary embolism was significantly lower in patients not receiving AP: 1.8% vs 12.4%; OR 0.12 (95% CI: 0.07–0.22; p=.001). Mortality of pts avoiding AP was also significantly lower (23.7% vs 38%), OR 0.5 (95% CI: 0.4–0.6; p=.0001) In the multiple logistic regression analysis only advanced cancer and to be given AP were significantly associated with mortality. No major bleeding was recorded among pts assigned to receive continuous AP. Conclusions: The results of the present study do confirm the current drugs and schedules for AP are unable to prevent not only catheter-related thrombosis but also systemic VTE. Mortality does appear lower in those not treated with AP and the difference still exists after adjustment for age, history of previous VTE and to be given chemotherapy. The attitude to give a continuous AP to pts with central lines presenting with more severe disease or at increased thromboembolic risk seems to be ineffective if not dangerous. No significant financial relationships to disclose.

Abstract
3505 Background: In ACC “FOLFIRI” is one of the standard regimens and is able to obtain about 40% response rate (RR) with an overall survival (OS) of 17–18 months. Experimental studies (Sobrero, 2000) indicate that an alternating chemotherapy could delay the appearance of cell resistance and reduce the therapeutic load for patients (pts). Methods: In order to evaluate whether intermittent “FOLFIRI” (CPT-11: 180 mg/sqm d1 + l-folinic acid -FA: 100 mg/sqm in 2 hr + 5fluorouracil-5FU: 400 mg/sqm bolus + 600 mg/sqm 22 hr infusion, d 1 and 2 every 2 weeks, for 2 months on and 2 months off) (arm A) was at least as effective as continuous “FOLFIRI” (same regimen, every month) (arm B), until progression in both arms, 336 pts from 27 Centers were randomised from 7/2001 to 6/2005. The characteristics of pts were: median age 64 years (r 29–75), males 214 (63%), PS 0: 222 (66%), liver mets only 166 (49%), multiple mts including liver 80 (24%). Results: RR was 29% in arm A and 35% in arm B, with a median progression-free survival (PFS) of 8.8 and 7.3 months respectively (HR = 1.00, 95% CI: 0.74 - 1.36). At a median follow-up of 27 months, median overall survival (OS), the primary endpoint of the trial, was 16.9 months in arm A and 17.6 in arm B (HR = 1.11, 95% CI: 0.83 - 1.48). Toxicity was acceptable and similar in the 2 arms (WHO grade 3–4 toxicity: neutropenia in 12% pts, diarrhoea in 11%, nausea/vomiting in 4% and fatigue in 3%). Conclusions: Our results demonstrate that alternating “FOLFIRI” obtains the same survival as a continuous treatment, thus reducing the discomfort to pts and the economic costs. No significant financial relationships to disclose.

Abstract
Docetaxel (75 mg m(-2) 3-weekly) is standard second-line treatment in advanced non-small-cell lung cancer (NSCLC) with significant toxicity. To verify whether a weekly schedule (33.3 mg m(-2) for 6 weeks) improved quality of life (QoL), a phase III study was performed with 220 advanced NSCLC patients, < or =75 years, ECOG PS < or =2. QoL was assessed by EORTC questionnaires and the Daily Diary Card (DDC). No difference was found in global QoL scores at 3 weeks. Pain, cough and hair loss significantly favoured the weekly schedule, while diarrhoea was worse. DDC analysis showed that loss of appetite and overall condition were significantly worse in the 3-week arm in the first week, while nausea and loss of appetite were more severe in the weekly arm in the third week. Response rate and survival were similar, hazard ratio of death in the weekly arm being 1.04 (95% CI 0.77-1.39). A 3-weekly docetaxel was more toxic for leukopenia, neutropenia, febrile neutropenia and hair loss; any grade 3-4 haematologic toxicity was significantly more frequent in the standard arm (25 vs 6%). The weekly schedule could be preferred for patients candidate to receive docetaxel as second-line treatment for advanced NSCLC, because of some QoL advantages, lower toxicity and no evidence of strikingly different effect on survival.

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

Abstract
DCEP (dexamethasone, cyclophosphamide, etoposide, and cisplatin) has proved to be an effective salvage therapy for refractory-relapsed MM patients. Little is known, however, about its potential as mobilizing therapy. The aim of this study was to evaluate the efficacy of DCEP in mobilizing PBSC and to define its toxicity. Fifty-five MM patients received DCEP followed by G-CSF as part of high-dose programs including autologous transplantation. At the time of mobilization, 40 patients had previously received VAD only, and 15 alkylating agents. Mobilization was successful (minimum number of CD34(+) cells 2 x 10(6)/kg) in 48/55 patients (87%), and 41/55 patients (75%) collected >4 x 10(6)/kg CD34(+) cells. Of the seven patients who did not mobilize stem cells, five (71%) had been previously exposed to alkylating agents. The median number of CD34(+) cells harvested was 5.8 x 10(6)/kg (range 2.1-22.4). There was no treatment-related mortality. The side-effects of DCEP were always tolerable. No neutropenia <1000/microl nor thrombocytopenia <50,000/microl were observed. No patient required transfusion as a consequence of therapy, or hospitalization for septic complications. In conclusion, DCEP, in addition to its demonstrated anti-tumor activity, is an effective regimen for mobilizing peripheral blood progenitor cells in myeloma patients, with little or no side-effects. These properties render DCEP a useful regimen for the debulking and mobilization phase of high-dose programs for multiple myeloma.

Abstract
Loss of bone mass is a process which generally becomes manifest in women during the fourth decade of life and is considerably accelerated following the onset of menopause, especially if this in surgically induced. Bone mineral metabolism was studied in 104 women, subdivided into the following groups: group 1: 33 women with normal menstrual cycles; group 2: 30 women in pre-menopause; group 3: 38 women who had undergone ovariectomy but had not received any osteotrope treatment; group 4: 33 ovariectomised women who had been treated immediately after surgery with calcium (1 g/die per os) in addition to synthetic salmon calcitonin nasal spray (100 IU on alternate days). Patients in groups 2-4 were analysed on entry into the study (time 0) and after 6 and 12 months of menopause (natural or surgical) using biochemical tests (alkaline phosphatase, calcium and phosphorus metabolism, PTH and osteocalcin) and by calculating bone mineral content (BMC) using a single photon ray performed at 3 cm and 8 cm from the styloid apophysis of the radius. The groups were matched for age, body mass index, dietary and sexual habits, geographic area. The results obtained can be summarised as follows: a) the concentrations of the main biochemical parameters were found to be normal and substantially similar between all groups at time 0; however, after 12 months increments relating to alkaline phosphatase and osteocalcin were significantly higher in ovariectomised women who did not receive treatment compared to ovariectomised patients treated with calcium + calcitonin, thus indicating a lower bone turnover in the latter group. b) BMC values, measured at the distal radius.

Abstract
Forty-seven patients with stage III nonsmall cell lung cancer (NSCLC) were treated with the sequential administration of combination chemotherapy consisting of cisplatin, epirubicin and etoposide and of irradiation plus lonidamine. The response rate was 49% after chemotherapy with an improvement of 14% after radiation therapy and lonidamine. The median survival was around 15 months for responders and 9 months for nonresponders. Toxicity was moderate and acceptable. It is concluded that this schedule is active in the treatment of NSCLC.

Abstract
Alcohol abuse is a frequent contributor to elevated blood pressure. 710 chronic alcoholics, aged 26-60 years, admitted for detoxification were studied. We compared hypertension prevalence in alcoholics with that in a similar group of non-alcoholics matched for age, sex, and miscellaneous diseases. The prevalence of hypertension was higher in heavy drinkers (11.4%) than in non drinker subjects (3.4%). Abstinence from alcohol during hospitalization was followed by normalization of hypertensive status in a high percentage of patients (70%). The majority of hypertensive alcoholics (75%) developed target organ damage ranging from retinopathy to hypertensive cardiomyopathy and renal lesion. In a 4.6 +/- 2.8 years follow-up study of 42 hypertensive alcoholic subjects, we observed that hypertension was 26% in those who abstained alcohol ingestion versus 84% in those who remained actively alcoholics. Four patients died of liver failure and two of stroke.

Abstract
We investigated the zinc concentration in blood and the effect of zinc supplementation in 11 male outpatients seropositive for human immunodeficiency virus at stage 5 according to the Walter Reed classification. Zinc concentration was measured in serum, platelets, mononuclear and polymorphonuclear cells, and erythrocytes. There was a significant increase in serum zinc concentration after zinc administration, but the zinc level in blood cells remained unchanged. All patients showed a progressive gain in body weight and a slight elevation in levels of CD4+ cells. No adverse side-effects were noticed.

Abstract
Low-density lipoprotein apheresis (LDL-apheresis) was done with either cascade filtration (DF) or dextran sulfate cellulose adsorption (DSC) in a patient with primary biliary cirrhosis who developed severe dyslipidemia associated with cholestasis and accumulation of lipoprotein-X (LP-X). The extracorporeal treatment was initially performed weekly, and resulted in a sharp drop in total cholesterol from 1038 to 430 mg/dl. During the next four months the patient was treated every 10-15 days, and pre-apheresis cholesterol levels were maintained between 438 and 505 mg/dl, until an orthotopic liver transplantation was successfully performed. With semi-selective DF a mean 47.1% of total cholesterol was removed per procedure compared to 30.0% with DSC, although the volume of treated plasma was 38.0 vs 49.9 ml/kg body weight. The changes in plasma cholesterol levels during DSC and DF showed that the kinetics of cholesterol removal were similar with both techniques, but the efficacy differed; DF removed both LDL and LP-X from plasma, whereas DSC selectively lowered the LDL content. Cascade filtration may therefore be considered as a first-choice treatment for patients with LP-X accumulation due to cholestasis.

Abstract
Forty-two male patients with alcoholic liver disease were studied for iron status by indirect hematological assays, including red cell ferritin (RCF), and histochemical estimations. Serum iron and ferritin, total iron-binding capacity levels were unrelated to iron deposits, whereas RCF concentration was a good index of iron stores as detected by direct assessment on bone marrow and liver biopsy specimens. A relatively high proportion of alcoholics (19%) were iron-deficient. Alcoholic patients with cirrhosis exhibited higher RCF values than patients with alcoholic hepatitis. However, this increase was apparently unrelated to cirrhosis per se. In alcoholics we found that RCF was mainly related to levels of bone marrow iron. The increased RCF values observed in patients with hepatic siderosis was mediated by marrow iron stores. RCF can therefore be regarded as a useful test to distinguish patients with liver siderosis and normal values of bone marrow iron.

Abstract
A 27-year-old woman with severe chronic hemolytic anemia was found to have reduced red cell hexokinase activity when the degree of reticulocytosis was considered. This enzyme had normal pH-dependent activity, normal Km for glucose, fructose, and mannose, normal Km for Mg adenosine triphosphate (ATP)2- and Ki for glucose-1,6-diphosphate. Furthermore, the pH-dependence and orthophosphate dependence of Ki for glucose-1,6-diphosphate were normal. However, this hexokinase was inactivated rapidly at 44 degrees C. No abnormalities were found in the red cell hexokinase isozymic pattern when it was compared with the profile obtained from cells of similar age. The hexokinase specific activity was reduced in all the red blood cell fractions obtained by density gradient ultracentrifugation; a marked difference in the distribution of cells through the gradient was evident. Among the glycolytic intermediates, a significant decrease of 2,3-diphosphoglycerate was evident. ATP and glucose 6-phosphate were also reduced when compared with cells of similar. Glucose consumption of the hexokinase-deficient cells decreased, but the rate of glucose metabolized through the hexose monophosphate shunt was unchanged. Although the total hexokinase activity in lymphocytes was only reduced by 37%, a marked hexokinase deficiency was detected in blood platelets (20% to 25% of normal activity). The parents and one of two siblings of the patient were heterozygous for the defect, with 66% to 74% of normal erythrocyte hexokinase activity and reduced heat stability of the enzyme. These results, when compared with those obtained in previously reported cases of hexokinase deficiency, provide further evidence of the broad phenotypic variability that characterizes this disorder. Furthermore, it is suggested that failure of energy generation is probably the primary cause of hemolytic anemia in hexokinase deficiency.

Abstract
The paper reports the occurrence of myocardial infarctions in a patient with severe deficiency of blood coagulation factor XII (Hageman factor). Factor XII plays a central role in the intrinsic activation of fibrinolysis and consequently the defective intrinsic fibrinolytic activity detected in the present case casts some doubt on its role in the increased vulnerability to thrombotic accident.
