Abstract
Neuromyelitis optica spectrum disorder (NMOSD) and multiple sclerosis (MS) are inflammatory diseases of the CNS. Overlap in the clinical and MRI features of NMOSD and MS means that distinguishing these conditions can be difficult. With the aim of evaluating the diagnostic utility of MRI features in distinguishing NMOSD from MS, we have conducted a cross-sectional analysis of imaging data and developed predictive models to distinguish the two conditions. NMOSD and MS MRI lesions were identified and defined through a literature search. Aquaporin-4 (AQP4) antibody positive NMOSD cases and age- and sex-matched MS cases were collected. MRI of orbits, brain and spine were reported by at least two blinded reviewers. MRI brain or spine was available for 166/168 (99%) of cases. Longitudinally extensive (OR = 203), "bright spotty" (OR = 93.8), whole (axial; OR = 57.8) or gadolinium (Gd) enhancing (OR = 28.6) spinal cord lesions, bilateral (OR = 31.3) or Gd-enhancing (OR = 15.4) optic nerve lesions, and nucleus tractus solitarius (OR = 19.2), periaqueductal (OR = 16.8) or hypothalamic (OR = 7.2) brain lesions were associated with NMOSD. Ovoid (OR = 0.029), Dawson's fingers (OR = 0.031), pyramidal corpus callosum (OR = 0.058), periventricular (OR = 0.136), temporal lobe (OR = 0.137) and T1 black holes (OR = 0.154) brain lesions were associated with MS. A score-based algorithm and a decision tree determined by machine learning accurately predicted more than 85% of both diagnoses using first available imaging alone. We have confirmed NMOSD and MS specific MRI features and combined these in predictive models that can accurately identify more than 85% of cases as either AQP4 seropositive NMOSD or MS.

Abstract
Neuromyelitis optica spectrum disorders (NMOSD) and multiple sclerosis (MS) show overlap in their clinical features. We performed an analysis of relapses with the aim of determining differences between the two conditions. Cases of NMOSD and age- and sex-matched MS controls were collected from across Australia and New Zealand. Demographic and clinical information, including relapse histories, were recorded using a standard questionnaire. There were 75 cases of NMOSD and 101 MS controls. There were 328 relapses in the NMOSD cases and 375 in MS controls. Spinal cord and optic neuritis attacks were the most common relapses in both NMOSD and MS. Optic neuritis (p < 0.001) and area postrema relapses (P = 0.002) were more common in NMOSD and other brainstem attacks were more common in MS (p < 0.001). Prior to age 30 years, attacks of optic neuritis were more common in NMOSD than transverse myelitis. After 30 this pattern was reversed. Relapses in NMOSD were more likely to be treated with acute immunotherapies and were less likely to recover completely. Analysis by month of relapse in NMOSD showed a trend toward reduced risk of relapse in February to April compared to a peak in November to January (P = 0.065). Optic neuritis and transverse myelitis are the most common types of relapse in NMOSD and MS. Optic neuritis tends to occur more frequently in NMOSD prior to the age of 30, with transverse myelitis being more common thereafter. Relapses in NMOSD were more severe. A seasonal bias for relapses in spring-summer may exist in NMOSD.

Abstract
Neuromyelitis optica spectrum disorders (NMOSD) are an inflammation of the central nervous system associated with autoantibodies to aquaporin-4. We have undertaken a clinic-based survey of NMOSD in the Australia and New Zealand populations with the aim of characterising the clinical features and establishing the value of recently revised diagnostic criteria. Cases of possible NMOSD and age and sex-matched controls with multiple sclerosis (MS) were referred from centres across Australia and New Zealand. Cases were classified as NMOSD if they met the 2015 IPND criteria and remained as suspected NMOSD if they did not. Clinical and paraclinical data were compared across the three groups. NMOSD was confirmed in 75 cases and 89 had suspected NMOSD. There were 101 controls with MS. Age at onset, relapse rates and EDSS scores were significantly higher in NMOSD than in MS. Lesions and symptoms referable to the optic nerve were more common in NMOSD whereas brainstem, cerebellar and cerebral lesions were more common in MS. Longitudinally extensive spinal cord lesions were seen in 48/71 (68%) of cases with NMOSD. Elevations of CSF, white cell count and protein were more common in NMOSD. We have confirmed a clinical pattern of NMOSD that has been seen in several geographical regions. We have demonstrated the clinical utility of the current diagnostic criteria. Distinct patterns of disease are evident in NMOSD and MS, but there remains a large number of patients with NMOSD-like features who do not meet the current diagnostic criteria for NMOSD and remain a diagnostic challenge.

Abstract
A number of European studies have documented the ability of procalcitonin (PCT), a novel inflammatory marker, to discriminate patients with sepsis from those with other causes of systemic inflammatory response syndrome (SIRS). The aim of this study was to assess procalcitonin's performance in an Australian intensive care unit (ICU) setting to examine whether it could discriminate between these two conditions. One hundred and twenty-three consecutive adult ICU patients fulfilling criteria for SIRS were enlisted in the study. Over a period of five days, daily serum PCT and C-reactive protein (CRP) levels were measured. At least two sets of cultures were taken of blood, sputum/broncho-alveolar lavage (BAL) and urine. Other cultures were taken as clinically indicated. Questionnaires to ascertain clinical suspicion of sepsis were prospectively answered by the ICU senior registrars. PCT values were ten times higher in patients with positive blood cultures; CRP values were also significantly higher in the bacteraemic patients. Both PCT and CRP had a good ability to discriminate bacteraemia from non-infectious SIRS, with the area under receiver operating characteristics (ROC) curves for PCT being 0.8 and for CRP being 0.82. However neither PCT or CRP was able to discriminate patients with localized sepsis from those without. Utilizing both tests resulted in a more sensitive screen than either one alone, while PCT was a more accurate diagnostic test for bacteraemia than CRP. The PCT value also differed between those who died in hospital and those who survived. Measurement of PCT alone or in combination with CRP can aid discrimination of septicaemia/bacteraemia with associated SIRS from non-infectious SIRS in an Australian ICU setting.

Abstract
A membrane purification procedure and an immunoblotting assay have been designed to allow screening of human solid tumors for overexpression of the GP170 glycoprotein without employing a disaggregation method to obtain cell suspensions. The electrophoresed membrane proteins were probed, after Western Blotting, with the C219 monoclonal antibody and iodinated Protein A. The labeling intensity of the bands on the autoradioimmunoblots were quantified by densitometry. To test for the presence of GP170, we used membranes from the UV 2237 fibrosarcoma line and its adriamycin-resistant variant ADMR, grown in vitro or as solid tumor in mice. Membranes of human normal and tumor tissues obtained from previously untreated patients were also tested. An immunoreaction was observed in the adriamycin-resistant UV 2237 lines grown in vitro or in vivo. Quantitatively, the binding of the resistant cell line grown in vitro was higher than that observed in cells grown in mice. Bands in the GP 170 region were observed in 4/7 normal and in 7/7 tumor colon tissues and in the normal medulla from 2 patients with cancer of the renal cortex. No reaction could be found in samples from normal tissue, primary tumor or nodal metastasis from 7 patients with breast cancer.

Abstract
Adriamycin is an antibiotic, isolated from cultures of a mutant of Streptomyces peucetius, var. caesius, with a chemical structure very similar to daunomycin but with a higher therapeutic index in experimental tumors. The biological activity of this antibiotic has been studied in vitro on the HeLa cell strain. Adriamycin quickly penetrates into the cells and fixes to the nuclear structures with a marked localization at the level of the perinucleolar chromatin. It causes a marked and immediate disturbance of the mitotic process, viz. pre-prophasic inhibition at the low doses and mitotic block at the higher doses. Even the synthesis of DNA and RNA, evaluated autoradiographically as incorporation of 3H-thymidine and 3H-uridine, appear markedly inhibited. The viability of the cells, tested both as regards capacity to give rise to colonies and as regards proliferative activity of a cell population, was seriously reduced, in a degree proportional to the period of treatment and to the concentration of the antibiotic, until total inhibition. In comparison with daunomycin, adriamycin exerts an immediate antimitotic and anti-metabolic effect which, at equivalent doses, is slightly lower than that of daunomycin. The long-term antiproliferative activity on cellular proliferation is however, identical for the two antibiotics.

Abstract
The kinetic parameters of a 5-day growth of sarcoma 180 (ascites) have been determined, using both the labelled mitosis method after pulse labelling with 3H thymidine and the 3H and 14C thymidine double labelling technic. The two methods yielded reproducible results, labelling index 73 %; duration of the period of DNA synthesis (S phase) 13 hours (13.5 from double labelling: technic mitosis 0.24 (0.34) hours; G1 + G2 5.3 (4.76) hours; Te 18.5 (18.6) hours. The growth fraction obtained after repeated 3H thymidine injections was 0.95 and as calculated from the other kinetic parameters 0.98.

Abstract
An in vitro chemosensitivity test is described for the quantitative determination of the interference of antitumoral drugs on nucleic acid metabolism in short-term cultures of non-Hodgkin's malignant lymphomas. Preliminary biochemical studies have defined the optimal culture conditions and have guaranteed the reliability and the reproducibility of the test. Our results for adriamycin and prednisone are in agreement with those obtained on experimental systems with other techniques.

Abstract
Aims and background There is considerable evidence from studies on tumor-bearing animals that nutritional support aimed at maintaining a good nutritional status can indeed promote tumor growth. Experience in humans, however, is scanty and controversial, this issue never having been extensively investigated. The purpose of this study was to analyze whether there exists a relationship between nutritional status and tumor growth in patients with non-Hodgkin's lymphoma. The hypothesis behind it was that if it is true than an abundant availability of substrates promotes tumoral growth, then the better the nutritional status the higher the tumor cell proliferation. Methods Two hundred and forty six adult patients with non-Hodgkin's lymphoma were characterized according to nutritional status (percent of weight loss as compared to usual body weight, serum albumin, serum cholinesterase, number of lymphocytes) and rate of incorporation of 3H thymidine labelling index in the tumor tissue. The values of serum albumin, serum cholinesterase and lymphocytes were subdivided into three classes adopting as cut-off points the tertile values of their distribution, while weight loss was scored as a “no” and a “yes”. The association between nutritional parameters and labelling index was evaluated by a univariate analysis (X2 test and Mantel-Haenszel X2 test and the odds ratio) and by a logistic multiple regression model. Results Results of the univariate analysis show a statistically significant association between “poor” nutritional status (depressed nutritional indexes) and “high” labelling index (increased tumoural growth), while the multiple regression analysis found that the only significant association was that between low serum cholinesterase and high labelling index. Conclusions These data demonstrate for the first time in a large series of patients that maintenance of a good nutritional status does not have any deleterious effect on the tumor growth.

Abstract
The proliferative rate has been evaluated for several human tumor types as the fraction of cells in S-phase. The methodologies most often used are autoradiographic determination of 3H-thymidine incorporation and flow cytometric evaluation of DNA content. Cell kinetics determined on various solid primary tumors at the time of diagnosis is not related to pathologic stage but it is an indicator of clinical evolution of the disease similar or superior to other biologic and pathologic prognostic factors. In early disease, submitted to loco-regional treatment as a first-line therapy, the rate of cell proliferation provides prognostic information on relapse-free and overall survival. In this clinical situation, a different metastatic potential can be attributed to tumors with different proliferative rates. In more extensive disease, submitted to systemic treatment, proliferation indices generally influence overall survival, eventhough in responsive tumors a fast proliferative activity could be indicative of higher aggressiveness and remarkable chemosensitiveness. Proliferation indices of the metachronous metastatic lesions is increased over those of the primary tumors as a further evidence of the association between proliferative activity and disease progression.

Abstract
A short-term antimetabolic assay, which considers the interference with [3H]thymidine incorporation as an indicator of drug effect, has been used to comparatively assess the chemosensitivity of different tumor lesions from the same patient. The analysis was performed on primary tumors and their synchronous metastases from 67 patients with breast, ovarian, gastrointestinal and germ cell testicular tumors. A remarkable difference in sensitivity to cytostatic drugs was observed between the two lesions. In contrast, a strong association in chemosensitivity (81.7% agreement rate; p < 0.01) was observed between two synchronous metastases from 17 patients with breast, ovarian, germ cell testicular tumors or malignant melanoma. In addition, the predictive relevance of the antimetabolic assay on clinical response to chemotherapy was analyzed in relation to the type of tumor lesion tested in vitro in a retrospective correlative study on 57 patients with advanced ovarian and germ cell testicular tumors. The objective clinical response was significantly correlated to the in vitro sensitivity of metastases (83.7% agreement rate; p < 0.01), but not to that of the primary tumor.

Abstract
The activity of some alkylating agents widely used in clinical practice was studied by an in vitro antimetabolic assay, which evaluates the interference of drugs on the incorporation of 3H-thymidine and 3H-uridine in short-term cultures of human tumors. The effect of CCNU, chlorambucil, cisplatin, melphalan, prednimustine, procarbazine and the pro-active derivatives of cyclophosphamide and ifosfamide, 4-hydroperoxycyclophosphamide and 4-hydroperoxyifosfamide, was tested on non-Hodgkin lymphomas, germ cell testicular tumors, breast and ovarian cancers. Similar effects were generally produced by the drugs on both DNA and RNA precursor incorporation, and the in vitro response rates were similar to those clinically obtained for the same tumor types by using the same drugs in monochemotherapy. The effects of different alkylating agents on the individual tumors were not significantly associated, except for the analogues 4-hydroperoxycyclophosphamide and 4-hydroperoxyifosfamide, for which a significant agreement rate was observed. No evidence of acquired resistance to 4-hydroperoxycyclophosphamide and cisplatin after clinical treatment with the same drug was found in samples from ovarian cancer and non-Hodgkin lymphoma, but there was a definite trend in germ cell testicular tumors to lower sensitivity to cisplatin in previously treated patients.

Abstract
The clinical interest in HER-2/neu is related to trastuzumab, a drug used to treat patients with invasive breast carcinoma overexpressing the HER-2/neu protein. It is very important to correctly identify those patients who may benefit from trastuzumab by accurate assessment of the HER-2/neu status. Of the various methods available, the Dako Herceptest for immunohistochemical assay is considered the most reliable to reach this goal. The aim of this study was to investigate within a group of Italian laboratories the reproducibility of the results of HER-2/neu assessment by means of the Dako scoring system on slides stained with the Herceptest kit. This study was also conceived as the continuation of one of our previous studies, which was similar in its aims but different in the classification criteria adopted. Our results show that, whereas the intra-observer reproducibility was generally satisfactory, the interobserver reproducibility was not. Moreover, our findings confirm that the two extreme classes (0 and 3+) are more easy to identify than the other two and that the Herceptest does not allow to discriminate optimally between scoring classes 2+ and 3+. These findings are relevant in clinical practice where the treatment choice is based on categories defined by this assay, suggesting the need of adopting educational programs and/or new reference materials to improve the assay performance.

Abstract
Extractable nuclear antigen (ENA) antibody testing is often requested in patients with suspected connective tissue diseases. Most laboratories in Australia use a two step process involving a high sensitivity screening assay followed by a high specificity confirmation test. Multiplexing technology with Addressable Laser Bead Immunoassay (e.g., FIDIS) offers simultaneous detection of multiple antibody specificities, allowing a single step screening and confirmation. We compared our current diagnostic laboratory testing algorithm [Organtec ELISA screen / Euroimmun line immunoassay (LIA) confirmation] and the FIDIS Connective Profile. A total of 529 samples (443 consecutive+86 known autoantibody positivity) were run through both algorithms, and 479 samples (90.5%) were concordant. The same autoantibody profile was detected in 100 samples (18.9%) and 379 were concordant negative samples (71.6%). The 50 discordant samples (9.5%) were subdivided into 'likely FIDIS or current method correct' or 'unresolved' based on ancillary data. 'Unresolved' samples (n = 25) were subclassified into 'potentially' versus 'potentially not' clinically significant based on the change to clinical interpretation. Only nine samples (1.7%) were deemed to be 'potentially clinically significant'. Overall, we found that the FIDIS Connective Profile ENA kit is non-inferior to the current ELISA screen/LIA characterisation. Reagent and capital costs may be limiting factors in using the FIDIS, but potential benefits include a single step analysis and simultaneous detection of dsDNA antibodies.

Abstract
The labeling index has been determined in 34 non-Hodgkin malignant lymphomas. The kinetic parameter has been analyzed in relation to the different histologic types, according to the Kiel calssification, and a kinetic classification with three main groups at low, intermediate, and high proliferative activity has been proposed. The analysis of the survival of the patients in relation to the labeling index of the malignant lymphoma cell population has shown that the potential proliferative activity has an important prognostic significance.

Abstract
560 Background: Antimetabolites are active in proliferating cells, and the adjuvant schedule CMF is highly effective in RPBC, whereas the sequential administration of doxorubicin (D) and CMF is superior to CMF–>D, especially in indolent tumors. In a phase III study, we evaluated whether adjuvant E followed by CMF is superior to the inverse sequence in RPBC. Methods: Patients with N-, T > 1 cm or ≤ 3 N+ and any T RPBC (defined by thymidine labeling index or grade or S-phase or Ki67/MIB1) were randomized to receive E (100 mg/m2 i.v. d 1, q 21 days for 4 cycles) followed by CMF (600, 40, 600 mg/m2 i.v. d 1 and 8, q 28 days for 4 cycles) (arm A) or CMF followed by E (arm B) or CMF (600, 40, 600 mg/m2 i.v. d 1 and 8, q 28 days for 6 cycles) (arm C). Arm C was closed after the EBCTCG 2000 meta-analysis (data not shown). The main endpoint was overall survival (OS), and the study had 80% power to detect a 7% absolute increase in 5-year OS with 400 patients per arm. Results: From November 1997 to December 2004, 1066 patients were enrolled (arms A/B/C: 440/438/188): N- 53%, estrogen receptor positive 63%, grade 3, 77%. At a median follow up of 69 months, 5-year disease-free survival was 80% in both arms (A and B) (p = 0.93, logrank test), with adjusted hazard ratio (AHR) 0.99 (95% CI 0.73–1.33, Cox model), and OS was 91% in arm A and 93% in arm B (p = 0.66, logrank), with AHR 0.88 (95% CI 0.58–1.35, Cox model). Adverse events were similar, apart from a small increase in grade 4 neutropenia in arm B. Conclusions: No relevant differences in clinical outcome were observed with the 2 different sequences. Further subgroup analyses are ongoing to verify the efficacy of each sequence as a function of biomolecular and hormonal profiles. No significant financial relationships to disclose.

Abstract
11062 Background: A promising approach for the early diagnosis of colorectal cancer (CRC) is the evaluation of genomic DNA integrity (FL-DNA) extracted from stool. Pilot and confirmatory studies carried out by our group have shown that, thanks to its diagnostic accuracy, this molecular assay could be a useful tool for the non-invasive, early diagnosis of CRC. The aim of the present study was to verify whether the FL-DNA method could represent a valid alternative to the fecal occult blood test (FOBT) or whether it could be used alongside FOBT in screening programs to unmask false FOBT positives and spare patients from unnecessary colonoscopy. For this purpose, stool samples were collected from all individuals participating in the FOBT (OC-Sensor, Alpha Wassermann) Regional Screening Program run by the Cancer Prevention Unit of Morgagni-Pierantoni Hospital in Forli. Methods: The program recruited subjects of either sex aged 50 to 69 years. Of the 560 individuals with FOBT-positive stool subjected to colonoscopy, 26 were diagnosed with adenocarcinoma, 264 with high-grade adenoma and 54 with low-grade adenoma. More than one third (216) of the group had only benign disease (hemorrhoids, diverticulitis, inflammation, etc), hyperplastic polyps or nothing. The integrity of fecal DNA was analyzed blindly by the FL-DNA test on the same specimen used for the occult blood determination. Results: Using a cut-off of 10 ng, the molecular analysis detected over 90% of the colorectal cancers and about 50% of the high- and low-grade adenomas. In particular, diagnostic accuracy was similar for lesions of any localization, level of dysplasia and histopathological characteristic, and higher for lesions > 2 cm and multiple lesions. The test also confirmed its capacity to identify colorectal cancer in asymptomatic individuals. Conclusions: FL-DNA represents a valid alternative to or support for approaches currently used in screening programs. A more in depth DNA stool evaluation in negative FOBT individuals could reveal the test's usefulness in unmasking colorectal tumors and adenomas missed by FOBT. No significant financial relationships to disclose.

Abstract
RATIONALE Much of the total disease burden and cost of chronic obstructive pulmonary disease (COPD) is associated with acute exacerbations of COPD (AECOPD). Serum amyloid A (SAA) is a novel candidate exacerbation biomarker identified by proteomic screening. OBJECTIVES To assess SAA as a biomarker of AECOPD. METHODS Biomarkers were assessed (1) cross-sectionally (stable vs. AECOPD; 62 individuals) and (2) longitudinally with repeated measures (baseline vs. AECOPD vs. convalescence; 78 episodes in 37 individuals). Event severity was graded (I, ambulatory; II, hospitalized; III, respiratory failure) based on consensus guidelines. MEASUREMENTS AND MAIN RESULTS Presumptively newly acquired pathogens were associated with onset of symptomatic AECOPD. In the cross-sectional study, both SAA and C-reactive protein (CRP) were elevated at AECOPD onset compared with stable disease (SAA median, 7.7 vs. 57.6 mg/L; P < 0.01; CRP median, 4.6 vs. 12.5 mg/L; P < 0.01). Receiver operator characteristics analysis was used to generate area-under-curve values for event severity. SAA discriminated level II/III events (SAA, 0.88; 95% confidence interval, 0.80-0.94 vs. CRP, 0.80; 95% confidence interval, 0.70-0.87; P = 0.05). Combining SAA or CRP with major symptoms (Anthonisen criteria, dyspnea) did not further improve the prediction model for severe episodes. IL-6 and procalcitonin were not informative. CONCLUSIONS SAA is a novel blood biomarker of AECOPD that is more sensitive than CRP alone or in combination with dyspnea. SAA may offer new insights into the pathogenesis of AECOPD.

Abstract
We evaluated the performance of anticardiolipin (aCL) and beta2-glycoprotein I (beta2-GPI) antibody assays through a large external quality assurance program. Data from the 2002 cycle of the Royal College of Pathologists of Australasia Quality Assurance Program (RCPA QAP) were analyzed for variation in reported numerical values and semiquantitative results or interpretations according to method type or group and in conjunction with available clinical data. High interlaboratory variation in numerical results and notable method-based variation, combined with a general lack of consensus in semiquantitative reporting, continues to be observed. Numerical results from cross-laboratory testing of 12 serum samples (for immunoglobulin G [IgG]-aCL, IgM-aCL, and IgG-beta2-GPI) yielded interlaboratory coefficients of variation (CVs) that were higher than 50% in six of 12 (50%) specimens for IgG-aCL, and 12 of 12 (100%) specimens for IgM-aCL and IgG-beta2-GPI. Semiquantitative reporting also varied considerably, with total (100%) consensus occurring in only four of 36 (11%) occasions. General consensus (where > 90% of participating laboratories agreed that a given serum sample gave a result of either negative or positive) was only obtained on 13 of 36 (36%) occasions. Variation in results between different method types or groups were also present, resulting in potential biasing of the RCPA QAP-defined target results by the large number of laboratories using the dominant aCL assays. Finally, laboratory findings frequently did not agree with the available clinical information. In conclusion, in a large proportion of specimens from the 2002 RCPA QAP cycle, laboratories could not agree on whether a serum sample tested was aCL-positive or aCL-negative, or beta2-GPI-positive or beta2-GPI-negative. Despite prior attempts to improve the standardization of testing and reporting practices, laboratory testing for aCL and anti-beta2-GPI still demonstrates significant interlaboratory and intermethod variation, which needs to be taken into account for the clinical interpretation of test results, especially those from different laboratories.

Abstract
The recent availability of the monoclonal antibody MIB-1 (which is able to detect the human nuclear cell proliferation-associated antigen Ki-67 even on formalin-fixed, paraffin-embedded sections, microwave-treated and routinely processed for immunohistochemistry) could open new avenues for validation of the clinical role of tumour cell proliferation on large, consecutive and unselected series of human tumours. However, the routine use of such a marker requires a methodological standardization as well as the comparative assessment of some technical and biological aspects. The MIB-1 index was determined in parallel samples from 50 consecutive invasive breast carcinomas processed with different fixatives for different times. The median values of MIB-1 indices following 2, 6 and 24 h of formalin fixation were similar (29.4%, 30.6% and 29.7%, respectively) and consistent with those reported in the literature; squared linear regression coefficients were 0.99. The median values of MIB-1 indices were markedly lower in Bouin-fixed, paraffin embedded, and in frozen samples (20.0% and 19.8%, respectively), with a poor correlation coefficient with the values detected following formalin fixation (R2 = 0.456). Moderate and poor correlations were observed between Ki-67 index and MIB-1 detected on frozen (rs, 0.78) or formalin-fixed, paraffin-embedded samples (rs, 0.47) and a minimal concordance was observed between TLI and MIB-1 or Ki-67 (rs, 0.25 and 0.22, respectively). Our results indicate interference of the fixative type on immunoreactivity to MIB-1 and also suggest that Ki-67 and MIB-1 reacted with different epitopes of the same antigen.

Abstract
An anticardiolipin antibody (ACA) assay has become a laboratory standard for the detection of antiphospholipid antibodies. We evaluated data from a quality assurance program to assess ACA assay usefulness. Cross-laboratory (n = 56) testing of 12 serum samples yielded interlaboratory coefficients of variation (CVs) for lgG ACA and IgM ACA that were higher than 50% in 17 (71%) of 24 cases. The situation for testing consensus was of equal concern. Total consensus occurred in 6 (25%) of 24 cases. General consensus (interlaboratory agreement, 90% or more) was obtained in 10 (42%) of 24 cases. In the majority of test cases, laboratories could not agree on whether a serum sample tested was ACA-positive or ACA-negative. Differing method-related issues also were evident; some methods tended toward higher or lower ACA values. Method-based majority consensus differed from participant majority consensus on many test occasions. Exceedingly high interlaboratory result variation, combined with a general lack of test result grading consensus and method-based variation, indicate that a cautious clinical approach toward laboratory findings is prudent. Laboratory tests should be repeated at least once before making a clinical diagnosis of any anti-phospholipid syndrome-like disorder.

Abstract
Biomarker analysis and evaluation in oncology is the product of a number of processes (including managerial, technical and interpretation steps) which need to be monitored and controlled to prevent and correct errors and guarantee a satisfactory level of quality. Several biomarkers have recently moved to clinical validation studies and successively to clinical practice without any definition of standard procedures and/or quality control (QC) schemes necessary to guarantee the reproducibility of the laboratory information. In Italy several national scientific societies and single researchers have activated -- often on a pilot level -- specific external quality assessment protocols, thereby potentially jeopardizing the clinical reality even further. In view of the seriousness of the problem, in 1998 the Italian Ministry of Health sponsored a National Survey Project to coordinate and standardize the procedures and to develop QC programs for the analysis of cancer biomarkers of potential clinical relevance. Twelve QC programs focused on biomarkers and concerning morphological, immunohistochemical, biochemical, molecular, and immunoenzymatic assays were coordinated and implemented. Specifically, external QC programs for the analytical phase of immunohistochemical p53, Bcl-2, c-erb-2/neu/HER2, and microvessel density determination, of morphological evaluation of tumor differentiation grade, and of molecular p53 analysis were activated for the first time within the project. Several hundreds of Italian laboratories took part in these QC programs, the results of which are available on the web site of the Network (www.cqlaboncologico.it). Financial support from the Italian Government and the National Research Council (CNR) will guarantee the pursuit of activities that will be extended to new biomarkers, to preanalytical phases of the assays, and to revision of the criteria of clinical usefulness for evaluating the cost/benefit ratio.

Abstract
In breast cancer, proliferative activity represents one of the biologic processes most thoroughly investigated for its association with tumor progression. In addition to the mitotic activity component of pathologic grading systems, several proliferation indices have provided independent information on prognosis and response to specific treatments in large retrospective studies. Recently, results from treatment protocols prospectively planned to test the clinical utility of proliferative activity have indicated that tumor cell proliferation markers identify two subsets among patients with lymph node-negative cancers: 1) those at a very low risk of relapse and 2) those who will benefit from regimens including antimetabolites. Future efforts should compare the prognostic accuracy of different proliferation markers, confirm preliminary evidence of a relationship between proliferation and response to specific systemic treatments, and standardize assay techniques to facilitate their transfer to general oncology practice.

Abstract
The accumulation of p53 protein was evaluated by a novel luminometric immunoassay (LIA) in cytosol samples from a series of 245 primary breast cancers. The cytosolic p53 content was not related to nodal status or hormone receptor status, but it was significantly and directly associated with tumor size and cell proliferation. A matched comparison between immunohistochemistry (IHC) and LIA results of individual tumors showed a significant association, albeit with a correlation coefficient of only 0.41. The agreement of results from the two assays was higher in node-positive, estrogen-receptor-negative and rapidly proliferating tumors than in the complementary subgroups. Overall, there was a significant trend in favor of an increase in p53 levels as determined by LIA with the increase in p53-positive cells shown by IHC. However, taking IHC detection as a reference, the sensitivity of the LIA was better for negative (86%) than for positive (61%) values. Based on these findings, a comparative assessment of the clinical relevance of LIA versus IHC results has to be recommended.

Abstract
At the Istituto Nazionale Tumori of Milan, a randomised adjuvant chemotherapy trial was carried out from 1982 to 1990 to compare alternating with sequential regimens of doxorubicin and CMF in 403 patients with more than 3 positive axillary nodes. Tumour proliferative activity was determined in 71% (285 cases) of women entering the clinical study. We investigated the relation between proliferative rate, determined as the [(3)H]thymidine labelling index (TLI) on tumour specimens obtained at diagnostic surgery, and clinical outcome following the 2 regimens, in which the same drugs were administered at the same dose intensity but with a different schedule. A high TLI was significantly associated with 12-year overall relapse (P = 0.009), distant metastasis (P = 0.001), and death (P = 0.002), even in the presence of information provided by tumour size, lymph node involvement, oestrogen receptors, and treatment regimen. The highest relapse-free survival (RFS) probability (45%, 95% CI 34-55%) was observed for patients with tumour TLI <5% and subjected to the sequential treatment. The lowest RFS probability (11%, 95% CI 0-26%) was observed for patients with tumour TLI >9% following the alternating regimen. Intermediate RFS probabilities, ranging from 23% to 34%, were observed for the other kinetic subgroups following the 2 treatment regimens. The benefit of sequential administration of doxorubicin and CMF was evident mainly in patients with tumours at low to intermediate proliferation.

Abstract
The predictive role of tumour proliferative rate and expression of p53, bcl-2 and bax proteins, alone and in association with tumour size, nodal involvement and oestrogen receptors (ER), was analysed on 145 elderly patients (> or =70 years of age) with histologically assessed node-positive breast cancers treated with radical or conservative surgery plus radiotherapy followed by adjuvant tamoxifen for at least 1 year. The 7-year probability of relapse was significantly higher for patients with tumours rapidly proliferating (hazard ratio (HR) = 2.0, P = 0.01), overexpressing p53 (HR = 4.4, P = 0.0001), weakly or not exhibiting bcl-2 (HR = 1.9, P = 0.02), without ERs (HR = 3.4, P = 0.0001) or with > or = 4 positive lymph nodes (HR = 2.3, P = 0.003) than for patients with tumours expressing the opposite patho-biological profile. Conversely, tumour size and bax expression failed to influence relapse-free survival. Adjustment for the duration of tamoxifen treatment did not change these findings. Oestrogen receptors, cell proliferation, p53 accumulation and bcl-2 expression were also predictive for overall survival. Within ER-positive tumours, cell proliferation, p53 accumulation, bcl-2 expression and lymph node involvement provided significant and independent information for relapse and, in association, identified subgroups of patients with relapse probabilities of 20% (low-risk group, exhibiting only one unfavourable factor) to 90% (high-risk group, exhibiting three unfavourable factors). Such data could represent the initial framework for a biologically tailored therapy even for elderly patients and highlight the importance of a patho-biological characterization of their breast cancers.

Abstract
Interest in translational studies on breast cancer is presently devoted to identify biological predictors of treatment response. In patients with operable breast cancer, subjected to primary and adjuvant chemotherapy, we analyzed the predictivity on objective clinical response and relapse-free survival of biological markers related to different cellular aspects and functions. Tumour proliferative rate (evaluated as the (3)H-thymidine-labelling index, TLI), oestrogen and progesterone receptors (ER and PgR, evaluated by the dextran-coated-charcoal method), nuclear DNA ploidy and the immunocytochemical expression of p53, bcl-2 and bax proteins were determined before primary treatment, at the time of diagnosis, and after primary chemotherapy, at surgery. Objective clinical response was significantly related only to pre-treatment p53 expression or PgR status, with a higher rate for tumours not expressing than for those expressing p53 (94% vs. 72%), as well as for PgR-negative (PgR(-)) than for PgR-positive (PgR(+)) tumours (86% vs. 68%). In the overall series, 8-year clinical outcome was significantly related only to post-treatment steroid receptors. In particular, higher 8-year relapse-free survival rate was observed for patients with ER(-) or PgR(-) than for those with ER(+) (64% vs. 38%) or PgR(+) (53% vs. 37%) tumours. Such findings held true even within the sub-set of patients who received adjuvant post-operative chemotherapy, i.e., those with node-positive (N(+)) or ER(-)/node-negative (N(-)) tumours, among whom also rapid proliferation or the presence of apoptosis-favouring markers (bcl-2(-) or bax(+), singly and in association) on surgical specimens identified a sub-set of women who benefited from systemic treatment. The different biological markers were variously indicative of clinical outcome, with a predictivity on tumour shrinkage for p53 and PgR, detected before primary chemotherapy, and on long-term follow-up for ER, PgR and, to a lesser extent, TLI and apoptosis-modulating markers.

Abstract
Antibodies that bind phospholipid (anti-phospholipid antibodies [APA]) are a focus of major interest to both clinical and laboratory personnel across a variety of disciplines because of the assortment of disorders with which they are reportedly associated. A solid phase assay using cardiolipin as the test phospholipid (anti-cardiolipin antibody assay [ACA]) has now become a laboratory standard for the detection of APA. In the current report, data from two separate external quality assurance programs (QAP) and collected over the past four years, have been evaluated to assess the utility of the ACA. Despite attempted standardizations, exceedingly high inter-laboratory variation and a general lack of test result consensus would signal the adoption of a cautious clinical approach towards laboratory findings. For example, for a total of 21 cross-laboratory tested serum samples (tested for both IgG and IgM for 41 quantitative estimations), inter-laboratory variation for both ACA-IgG and ACA-IgM was higher than 50% in 20 of 41 testing cases (48.8%). The situation with regard to testing consensus was equally concerning. Total consensus (i.e., 100% of participating laboratories agreed that a given serum sample gave an ACA result of either negative or positive) occurred in less than 20% of cases for ACA-IgG. More importantly, in about 50% of serum testing occasions there was no general consensus in returned laboratory data (i.e., more than 80% of labs could not agree on whether a serum sample tested was either ACA-positive or ACA-negative). Thus, despite attempted international standardizations, exceedingly high inter-laboratory variation and a general lack of test result consensus would argue that the assay has limited utility. We conclude that single point laboratory results must be used with considerable caution before accepting that ACA activity is present in patient serum or not. We agree with recommendations indicating that laboratory tests should be repeated at least once prior to making a clinical diagnosis of any APS-like disorder.

Abstract
Antineutrophil cytoplasmic antibody (ANCA) tests are used to diagnose and monitor inflammatory activity in the primary systemic small vessel vasculitides. ANCA is best demonstrated in these diseases by using a combination of indirect immunofluorescence (IIF) of normal peripheral blood neutrophils and enzyme-linked immunosorbent assays (ELISAs) that detect ANCA specific for proteinase 3 (PR3) or myeloperoxidase (MPO). For ANCA testing in "new" patients, IIF must be performed on all serum samples. Serum samples containing ANCA, any other cytoplasmic fluorescence, or an antinuclear antibody (ANA) that results in homogeneous or peripheral nuclear fluorescence then should be tested in ELISAs for PR3-ANCA and MPO-ANCA. Optimally, ELISAs for PR3-ANCA and MPO-ANCA should be performed on all serum samples. Inclusion of the most recent positive sample in the IIF or ELISA may help demonstrate a change in antibody level. Reports should use recommended terms. Any report of positive neutrophil fluorescence issued before the ELISA results are available should indicate that positive fluorescence alone is not specific for the diagnosis of Wegener granulomatosis or microscopic polyangiitis and that decisions about treatment should not be based solely on the ANCA results.

Abstract
In the last few decades, much effort has been directed towards identifying the phenotypic or functional aspect of tumor cells which can contribute to a biofunctional staging for improving the accuracy of pathologic staging used for identifying patients at different risk. Among known biologic factors, the proliferative capacity of the tumor cell population, a feature common to all tumors, has been widely investigated. Several approaches have been used to measure different aspects of the cell cycle. Among these, the thymidine labeling index (TLI) represents the fraction of cells in S-phase cell fraction and is based on the active incorporation of labelled thymidine into DNA. From basic studies conducted on several thousands of patients, the TLI of primary breast cancers appears closely related to steroid receptor status and generally unrelated to pathologic stage. Retrospective analyses performed on large series of patients treated with local regional therapy alone have consistently shown the relevance of TLI value to clinical aggressiveness in terms of relapse-free survival and overall survival. Moreover, TLI is a prognostic indicator which is independent of tumor size, steroid receptors, and p53 and bc12 protein expression, and which, together with patient age and tumor size, is able to identify patients at different risk of loco-regional or distant metastases. Recently, a direct relationship between TLI and response to polychemotherapy has been shown in patients with operable and advanced breast cancers. This finding, derived from retrospective and recently confirmed in prospective clinical studies, has led to the activation of cell kinetics based therapeutic protocols for patients with node-negative and one to three node-positive operable breast cancers.

Abstract
Interest in translational studies aimed at investigating the role of biologic markers in predicting clinical outcome of breast cancer patients and, in particular, response to specific treatments, has progressively increased. Among biologic variables presently under investigation, apoptosis markers, in particular Bcl-2 and Bax expression, are receiving much attention for their relationship with the cellular response to genotoxic damage in experimental tumors. Retrospective, independent studies were carried out by several research groups on about 5000 patients with breast cancer at different stages and with an adequate follow-up. The outcome of separate analyses as a function of treatment generally demonstrated that Bcl-2 overexpression, which correlates with biologic features of a differentiated phenotype (slow proliferation, high steroid receptor levels, absence of p53 and c-erB-2 expression), is associated with a favorable outcome. Such a finding is mainly evident following surgery as well as endocrine treatment. Conversely, no or weak Bcl-2 expression, alone or in association with bax overexpression, appears indicative of a radiation response, and preliminary emerging evidence supports the involvement of such an association of apoptosis-related markers even as predictors of long-term response to neoadjuvant cytotoxic treatment. Although the findings of an involvement of Bcl-2 and Bax as determinants of treatment response should be confirmed within the context of randomized clinical trials, they indicate a combined consideration of proteins that negatively and positively regulate apoptosis in translational studies on the effect of chemical and physical agents at a cellular level.

Abstract
AIMS (1) To assess a range of intravenous immunoglobulin products for atypical classical antineutrophil cytoplasmic antibody (C-ANCA) staining and to determine if this is present in patients treated with high dose intravenous immunoglobulin (2 g/kg/month) and replacement doses (200 mg/kg fortnightly); (2) using the United Kingdom national external quality assessment scheme (NEQAS), to determine if laboratories could differentiate this pattern from classical ANCA. METHODS ANCA testing was performed on 30 batches of intravenous immunoglobulin from several manufacturers. Six patients treated with high dose intravenous immunoglobulin and 11 receiving replacement doses of immunoglobulin for hypogammaglobulinaemia were tested for ANCA by indirect immunofluorescence on cytospin preparations of ethanol fixed neutrophils and by enzyme linked immunosorbent assay (ELISA). One of the positive immunoglobulin batches was tested blindly by 125 laboratories involved in NEQAS by indirect immunofluorescence and by ELISA in some laboratories. RESULTS 16 of 31 batches of intravenous immunoglobulin from six different manufacturers were atypical C-ANCA positive. Three of six patients receiving high dose intravenous immunoglobulin and none of 11 patients on replacement doses were atypical C-ANCA positive. The results of the NEQAS assessment by indirect immunofluorescence were 68% C-ANCA positive, 17% negative, 9% atypical C-ANCA, and 6% P-ANCA. CONCLUSIONS Some but not all intravenous immunoglobulin products yield a positive atypical cANCA by indirect immunofluorescence. An identical pattern may be observed in patients receiving high dose intravenous immunoglobulin but not in those on replacement doses. Of laboratories participating in NEQAS, 68% reported this pattern as cANCA. This reinforces the importance of reporting only "classical ANCA," defined by international ANCA workshops, to maintain the specificity of ANCA immunofluorescence and its close disease associations.

Abstract
The predictive role in terms of pathological response and prognostic role of biomarkers such as GST-pi, p53, bcl-2 and bax expression, immuno-histochemically detected, and of the S-phase cell fraction, autoradiographically determined as thymidine labeling index (TLI), were investigated within a prospective randomized phase III clinical trial on squamous-cell carcinoma of the oral cavity, including surgery or primary chemotherapy (PCT), which foresaw the prospective determination of biological markers. Pathological response was defined as the achievement after PCT of a pathological complete remission or the presence of microresidual disease. The study was performed on tumors obtained from a series of 100 previously untreated patients with resectable T2-4N0-2M0 carcinoma. All biomarkers were unrelated, except for an inverse relation between TLI and GST-pi and a direct relation between bcl-2 and bax expression. In patients treated with surgery alone, 3-year disease-free survival (DFS) appeared to be weakly, but not significantly, related only to GST-pi and p53 expression. In patients treated with PCT, pathological response and DFS were independent of p53 expression and cell proliferation. Conversely, low GST-pi and bax expression were indicative of pathological response but lost relevance as predictors of DFS, whereas absence of bcl-2 was associated with high probability of 3-year DFS in the overall series as well as in non-responding patients. Within this latter sub-set, all patients with bcl-2-positive tumors relapsed within 1 year of surgery, whereas a 60% probability of 3-year DFS was observed for patients with bcl-2-negative tumors (p = 0.02). This interim analysis appears to indicate that some biofunctional markers can provide information on pathological response to PCT and could help in understanding treatment efficacy at a cellular level.

Abstract
We have previously demonstrated that UCN-01, a potent protein kinase inhibitor currently in phase I clinical trials for cancer treatment, abrogates G2 arrest following DNA damage. Here we used murine FT210 cells, which contain temperature-sensitive Cdc2 mutations, to determine if UCN-01 abrogates G2 arrest through a Cdc2-dependent pathway. We report that UCN-01 cannot induce mitosis in DNA-damaged FT210 cells at the non-permissive temperature for Cdc2 function. Failure to abrogate G2 arrest was not due to UCN-01-inactivation at the elevated temperature because parental FM3A cells, which have wild-type Cdc2, were sensitive to UCN-01-induced G2 checkpoint abrogation. Having established that UCN-01 acted through Cdc2, we next assessed UCN-01's effect on the Cdc2-inhibitory kinase, Wee1Hu, and the Cdc2-activating phosphatase, Cdc25C. We found that Wee1Hu was indeed inactivated in UCN-01-treated cells, possibly just prior to Cdc2 activation and entry of DNA-damaged cells into mitosis. This inhibition appeared, however, to be a consequence of a further upstream action since in vitro studies revealed purified Wee1Hu was relatively resistant to UCN-01-inhibition. Consistent with such an upstream action, UCN-01 also promoted the hyperphosphorylation (activation) of Cdc25C in DNA-damaged cells. Our results suggest that UCN-01 abrogates G2 checkpoint function through inhibition of a kinase residing upstream of Cdc2, Wee1Hu, and Cdc25C, and that changes observed in these mitotic regulators are downstream consequences of UCN-01's actions.
