Abstract
The purpose of this phase II study was to evaluate the clinical efficacy of mitomycin C and vinblastine in patients with anthracycline-resistant metastatic breast cancer. This single-center, non-randomized trial enrolled 39 patients. Eligible patients must have received at least three chemotherapy regimens with epirubicin or CAF and had treatment failure while on chemotherapy or within 6 months of completing therapy. Treatment consisted of mitomycin C at a starting dose of 8 mg/m2 on day 1 and vinblastine (8 mg/m2, days 1 and 28). The regimen was repeated every 6 weeks with a 20% dose escalation of both drugs after the first cycle in the absence of grade III hematologic or other toxicity. On an intent-to-treat basis, 38 patients were eligible for assessment; 9 (23.7%, 95% confidence interval 1.92-2.45%) achieved a partial response and 13 (34.2%) had stable disease. The median time to disease progression was 6.21 ±4.26 months (range, 1-15; 95% confidence interval, 4.81-7.61), and the median survival was 10.76±7.6 (range, 1-29; 95% confidence interval 8.0-13.1%). Responsive patients had a significantly better survival than those with stable and progressive disease. Treatment was well tolerated. Anemia and neutropenia (grade I-III) developed in 28.9% and 26.3% of the patients, respectively. One patient with grade III granulocytopenia developed fever and infection that required hospitalization. Moderate neurotoxicity, myalgia, constipation, diarrhea and alopecia were observed. No toxic death occurred. Mitomycin C plus vinblastine is an effective and well-tolerated regimen for anthracycline resistant cancer.

Abstract
Dipyridamole, an inhibitor of nucleoside transport, increases the activity of 5-fluorouracil in a dose-dependent manner. The purpose of the present study was to determine whether dipyridamole with 5-fluorouracil and leucovorin gave an improved therapeutic outcome. Sixty patients entered in the present pilot study had previously received 5-fluorouracil (450 mg/m2) and leucovorin (100 mg/m2), every week, and relapsed during this treatment, which ended at least 6 weeks prior to study entry. Dipyridamole was administered at three different dosing schedules (DS) and methods of administration in three groups of patients. DS I: dipyridamole, 30 mg/m2 in normal saline solution, in 90 min iv infusion, followed by leucovorin, 100 mg/m2 iv push, followed by 5-fluorouracil, 450 mg/m2 in normal saline solution, in 60 min iv infusion, dipyridamole tablets (75 mg) every 12 hrs, continuously during the time of chemotherapy. DS II: dipyridamole, 50 mg/m2 in normal saline solution, in 90 min iv infusion, and the rest was the same as DS I. DS III: without oral dipyridamole, patients received dipyridamole (50 mg/m2) iv in the same manner as in DS I and II. Treatment was continued until tumor progression or unacceptable toxicity. All patients (n = 60) entered in the present study were assessable for response and toxicity. No complete response was observed. No patient at DS I responded, whereas 2 patients at DS II and 3 at DS III had a partial response (P <0.1). Stable disease was found with DS I (n = 1), DS II (n = 8) and DS III (n = 9) (P <0.01). More patients progressed at DS I (n = 19) than at DS II (n = 10) and DS III (n = 8) (P <0.0007). The median duration of response was 11 weeks (range, 8-16). Time to progression was 17 weeks for DS I, 15 weeks (range, 10-19) for DS II, and 14 weeks (range, 11-21) for DS III (P = 0.43). Median survival did not differ significantly between DS I (29 weeks; range, 14-48), DS II (31.5 weeks; range, 17-63) and DS III (36 weeks; range, 16-58) (P = 0.2). Neutropenia was most severe with DS I (grade 2, P <0.01) and DS II (grade 1, P <0.05) and nausea/vomiting with DS I (grade 0, P < 0.0005, grade 1, P <0.0002, grade 2, P <0.02) and DS III (grade 3, P <0.0009). Diarrhea was most severe in DS II (grade 3, P <0.005). Mucositis was increased in DS II (grade 0, P <0.008), anorexia in DS II (grade 0, P <0.032) and fatigue in DS I (grade 0, P <0.003). More patients in DS I than with the other two DS experienced headache (P <0.044). According to the response achieved at DS III (15% partial response and 45% stable disease) and the toxicity which was well tolerated mainly in this DS (except for nausea and vomiting grade 3, P <0.009), it can be stated that DS III is the appropriate dose and the simplest schedule of administration (administration of dipyridamole during therapy only). In conclusion, it appears that dipyridamole might still have a role in enhancing the clinical activity of drugs involved in the inhibition of the thymidylate synthetase biochemical pathway and its activity in combination with these agents (5-fluorouracil + leucovorin) as frontline treatment should therefore be explored in future phase II studies.

Abstract
Sixty patients with advanced gastric carcinoma who refused to receive cytotoxic chemotherapy were examined for serum immunoglobulin levels (IgG, IgM, IgA, IgE). Three samples were obtained every two months thereafter. The group of patients who had above-normal values of one or more of the examined immunoglobulins had a longer survival than the other (p<0.024). Immunoglobulin values were independent of the Helicobacter pylori antibody titer and of acute phase reactants. It is concluded that survival potentially correlates with serum immunoglobulin levels. Further studies including larger numbers of patients and correlating serum immunoglobulin levels with specific clinical parameters are needed to establish the prognostic role of serum immunoglobulins in patients with gastric carcinoma.

Abstract
IntroductionEuropean data on health-related quality of life (HRQoL) in adults with attention deficit/hyperactivity disorder (ADHD) in the general population is sparse.Aims and objectivesTo report HRQoL in UK adults with ADHD.MethodsUK residents aged 18–55 years with a diagnosis of adult ADHD completed an online, cross-sectional survey including questions on disease history, the EuroQol Five Dimensions questionnaire with five-levels (EQ-5D-5L) and the Work productivity and activity impairment questionnaire: general health (WPAI:GH). ADHD symptom severity was assessed by telephone using ADHD rating scale version IV with adult prompts (ADHD-RS-IV).ResultsThe survey was completed by 233 participants (65.2% women; 77.3% white British), mean age 32.6 years (standard deviation [SD] 9.5), mean ADHD-RS-IV total score 43.46 (SD 7.88). Their mean EQ-5D-5L utility score of 0.74 (SD 0.21) was lower than the UK population norm of 0.86 (SD 0.23).[1] WPAI:GH scores indicated that health problems resulted in impairments of 32.04% in work productivity and 45.79% in regular daily activities. Regression analyses adjusting for gender, age and comorbidities demonstrated associations between EQ-5D-5L utility scores and gender (men had lower scores, P < 0.001), work impairment due to health problems (increasing impairment was associated with lower scores, P = 0.005) and age (for each additional year of age, scores decreased by 0.007, P = 0.010).ConclusionsThese results highlight the impact on health utility, work productivity and regular daily activities, and add to the description of the disease burden of adult ADHD in the UK.This study was funded by Shire Development LLC.Disclosure of interestKings College London research support account for Asherson received honoraria for consultancy to Shire, Eli-Lilly and Novartis educational/research awards from Shire, Lilly, Novartis, Vifor Pharma, GW Pharma and QbTech speaker at sponsored events for Shire, Lilly and Novartis.

Abstract
This study investigates the relationship between fine resolution, local-scale biophysical and socioeconomic contexts within which land degradation occurs, and the human responses to it. The research draws on experimental data collected under different territorial and socioeconomic conditions at 586 field sites in five Mediterranean countries (Spain, Greece, Turkey, Tunisia and Morocco). We assess the level of desertification risk under various land management practices (terracing, grazing control, prevention of wildland fires, soil erosion control measures, soil water conservation measures, sustainable farming practices, land protection measures and financial subsidies) taken as possible responses to land degradation. A data mining approach, incorporating principal component analysis, non-parametric correlations, multiple regression and canonical analysis, was developed to identify the spatial relationship between land management conditions, the socioeconomic and environmental context (described using 40 biophysical and socioeconomic indicators) and desertification risk. Our analysis identified a number of distinct relationships between the level of desertification experienced and the underlying socioeconomic context, suggesting that the effectiveness of responses to land degradation is strictly dependent on the local biophysical and socioeconomic context. Assessing the latent relationship between land management practices and the biophysical/socioeconomic attributes characterizing areas exposed to different levels of desertification risk proved to be an indirect measure of the effectiveness of field actions contrasting land degradation.

Abstract
Indicator-based approaches are often used to monitor land degradation and desertification from the global to the very local scale. However, there is still little agreement on which indicators may best reflect both status and trends of these phenomena. In this study, various processes of land degradation and desertification have been analyzed in 17 study sites around the world using a wide set of biophysical and socioeconomic indicators. The database described earlier in this issue by Kosmas and others (Environ Manage, 2013) for defining desertification risk was further analyzed to define the most important indicators related to the following degradation processes: water erosion in various land uses, tillage erosion, soil salinization, water stress, forest fires, and overgrazing. A correlation analysis was applied to the selected indicators in order to identify the most important variables contributing to each land degradation process. The analysis indicates that the most important indicators are: (i) rain seasonality affecting water erosion, water stress, and forest fires, (ii) slope gradient affecting water erosion, tillage erosion and water stress, and (iii) water scarcity soil salinization, water stress, and forest fires. Implementation of existing regulations or policies concerned with resources development and environmental sustainability was identified as the most important indicator of land protection.

Abstract
An approach to derive relationships for defining land degradation and desertification risk and developing appropriate tools for assessing the effectiveness of the various land management practices using indicators is presented in the present paper. In order to investigate which indicators are most effective in assessing the level of desertification risk, a total of 70 candidate indicators was selected providing information for the biophysical environment, socio-economic conditions, and land management characteristics. The indicators were defined in 1,672 field sites located in 17 study areas in the Mediterranean region, Eastern Europe, Latin America, Africa, and Asia. Based on an existing geo-referenced database, classes were designated for each indicator and a sensitivity score to desertification was assigned to each class based on existing research. The obtained data were analyzed for the various processes of land degradation at farm level. The derived methodology was assessed using independent indicators, such as the measured soil erosion rate, and the organic matter content of the soil. Based on regression analyses, the collected indicator set can be reduced to a number of effective indicators ranging from 8 to 17 in the various processes of land degradation. Among the most important indicators identified as affecting land degradation and desertification risk were rain seasonality, slope gradient, plant cover, rate of land abandonment, land-use intensity, and the level of policy implementation.

Abstract
This phase II trial studied the efficacy and toxicity of full dose paclitaxel plus vinorelbine, as salvage chemotherapy in patients with metastatic breast cancer resistant to anthracyclines. Patients received vinorelbine (30 mg/m2) followed 1 hour later by full dose paclitaxel (175 mg/m2) every 3 weeks for a maximum of 8 cycles or until disease progression. Because of the heavy pretreatment of the patients, prophylactic granulocyte-colony stimulating factor (5 microg/kg) was administered daily for 5-10 days. To minimize potentially cumulative neurotoxicity due to both agents, amifostine was given prior to chemotherapy. Thirty-four patients: 8 with tumors primary resistant and 26 with tumors recurring within 3-6 months after anthracycline treatment, were evaluable for efficacy and toxicity. Objective responses occurred in 11 patients [32%; 95% confidence interval (CI): 16.3-47.7%), all partial responses. Responses were observed in lung and liver. The median response duration was 4 months (range 3-7), median time to progression was 5 months (range 3-9) and median overall survival was 8 months (range 4-24). Neutropenia was dose limiting (35% grade 3-4 toxicity). The left ventricular ejection fraction, measured and followed in 18 patients, fell less than 20% below baseline level in 9 patients (50%), but only one patient developed congestive cardiac failure. The paclitaxel-vinorelbine regimen was moderately tolerated and moderately effective in poor prognosis breast cancer patients with visceral metastases and tumors resistant to anthracyclines. The combination at these doses and schedules should be considered in the design of regimens for advanced breast cancer.

Abstract
The established clinical activity of docetaxel and ifosfamide as single agents in anthracycline pre-treated breast cancer, led us to conduct a phase I-II study to define the maximum tolerated dose (MTD), dose-limiting toxicities (DLTs), and clinical activity of the docetaxel+ifosfamide combination in this setting. Patients with histologically confirmed metastatic breast cancer, after failure on prior anthracycline-based chemotherapy, were treated at successive dose levels (DLs) in cohorts of 3-6 with escalated doses of docetaxel 70-100 mg/m(2) over 1 h on day 1 followed by ifosfamide 5-6 g/m(2) divided over days 1+2 (2.5-3.0 g/m(2)/day over 1 h), every 21 days. G-CSF was added once dose-limiting neutropenia was encountered at a certain DL and planned to be incorporated prophylactically in subsequent higher DLs. Between March 1997 and December 2002, 65 patients with a median age of 57 years (range, 32-72) and performance status (WHO) of 1 (range, 0-2) were treated at 5 DLs as follows; 21 in phase I DLs (DL1: 3, DL2: 6, DL3: 3, DL4: 6, and DL5: 3) and the remaining 44 were treated at DL4 (total of 50 patients at DL4), which was defined as the level for phase II testing. All patients were assessable for toxicity and 62 for response. DLT (with the addition of G-CSF after DL2) was reached at DL5 with 2/3 initial patients developing febrile neutropenia. Clinical response rates (RRs), on an intention-to-treat basis, in phase II were: 56%; (95% CI, 42.2-69.7%); 4 CRs, 24 PRs, 10 SD and 12 PD. The median response duration was 7 mo (3-24 mo), median TTP 6.5 mo (0.1-26 mo), and median OS 13 mo (0.1-33 mo). Grade 3/4 toxicities included: neutropenia in 72% of patients, with 60% developing grade 4 neutropenia (<or=7 days) and in 10% of these febrile neutropenia, while no grade 3/4 thrombocytopenia was observed. Other toxicities included peripheral neuropathy grade 2 only in 10%, grade 1/2 reversible CNS toxicity in 16%, no renal toxicity, grade 2 myalgias in 8%, grade 3 diarrhea in 8%, skin/nail toxicity in 14%, and grade 2 fluid retention in 2% of patients. One patient in the study treated at phase II died as a result of acute liver failure after the first cycle. The present phase I-II study has determined the feasibility, defined the MTD and demonstrated the encouraging activity of the docetaxel-ifosfamide combination in the phase II part of the study. Therefore, future randomized phase III studies versus single-agent docetaxel or combinations of the latter with other active agents are warranted.

Abstract
Background: Malignant mixed Mullerian tumours (MMMTs) of the uterus and adnexa represent aggressive gynaecologic malignancies with a high rate of loco-regional and distant failure. For that reason, we evaluated the paclitaxel–ifosfamide–carboplatin (TICb) combination in patients with advanced MMMTs. Methods: Female patients with advanced MMMTs, WHO-PS 0–2, no prior chemotherapy for systemic disease, unimpaired haemopoietic and organ function were eligible. Chemotherapy was administered at the following doses; paclitaxel: 175 mg m–2 on day 1, ifosfamide: 2.0g m–2 day–1 – days 1 and 2, and carboplatin at a target area under the curve 5 on day 2, with prophylactic G-CSF from day 3. Results: Forty patients of a median age 61 (45–72) years, performance status 0–2 with advanced MMMTs of the uterus (n=34), tubes (n=2) or ovary (n=4) have entered and all were evaluable for response and toxicity. Responses were as follows: 27 out of 40 (67.5%) evaluable patients responded, with 11 complete responses and 16 partial responses, while 10 had stable disease, and 3 developed progressive disease. The median response duration was 9 months (range, 4–40 months), median progression-free survival 13 months (range, 3–42 months), while median overall survival 18 months (range, 4–48 months). Grade 3/4 neutropenia was recorded in 22 out of 40 (55%) – with 13 developing grade 4 (⩽7 days) and 7 out of 40 (17.5%) of patients at least one episode of febrile neutropenia. Conclusion: In this study, it appears that the TICb combination, yielded important activity with manageable toxicity in females with advanced MMMTs warranting further randomised comparison with current standard regimens.

Abstract
Most pancreatic adenocarcinoma patients present with locally advanced or metastatic disease at diagnosis. in this retrospective study the authors evaluated the prognostic significance of the CEA and CA-19.9 serum tumor markers in advanced (unresectable) pancreatic cancer in correlation to other prognostic factors (demographic data, clinical parameters, treatment modality) and survival time using univariate and multivariate methods, in 215 patients with locally advanced (unresectable) or metastatic pancreatic adenocarcinoma. median survival was 29.0 weeks, with 21.9% of patients surviving 36 weeks. Among 24 potential prognostic variables, 19 were associated with shorter survival. Multivariate analysis indicated that ten factors had a significant independent effect on survival: chemotherapy, surgery, tumor localization, elevated C-reactive protein, elevated CeA, CA 19-9 (>30 x nl), jaundice at diagnosis, weight loss >10%, distant metastases, and Karnofsky performance status. Patients who had only palliative therapy had a hazard ratio of 8.94 versus those who underwent palliative surgery and chemotherapy. Although certain clinical, biochemical and biological factors remain important predictors of survival in patients with advanced pancreatic cancer, CA-19.9 serum tumor marker levels retain independent prognostic value for poor survival.

Abstract
5517 Background: Malignant mixed mullerian tumors (MMMTs) of the uterus and adnexa represent aggressive gynecologic malignancies with a high rate of locoregional and distant failure. For that reason we evaluated the TICb combination in patients with advanced MMMTs. Methods: Patients with advanced MMMTs [stages III-IV and relapses after surgery (Sx)±RT], WHO-PS 0–2, no prior chemotherapy, unimpaired hematopoietic/organ function were eligible. Chemotherapy was administered as follows; T: 175 mg/m2 d1, I: 2.0 g/m2/d-d1+2, and Cb at a target AUC = 5 (according to creatinine clearance based on Calvert's formula) on d2 after I. G-CSF was administered from day 3–7. Results: Thirty-two patients with MMMTs of the uterus (n = 28), tubes (n = 2), or ovary (n = 2) have entered so far and all are evaluable for response and toxicity: median age = 61 (45–72), PS = 1 (0–1), stages; III = 18 (56%), IV = 14 (44%), histologies were; with homologous sarcoma component: 21, with heterologous component: 11. Prior treatment for locoregional disease included Sx: 23, Sx+RT: 9. Disease sites at diagnosis included: pelvic disease 12; pelvic/paraortic lymph nodes 14; peritoneal implants 16; liver 4; lung nodules 9; bone metastases 1; malignant pleural effusion 4. Responses were as follows: 21/32 (66%) evaluable patients responded, with 9 complete responses (CR) and 12 partial responses (PR), while 8 had stable disease (SD), and 3 developed progressive disease (PD). The median response duration was 8 mo (4–28), median time-to-progression (TTP) 12.5mo (4–26), while median overall survival (OS) has not been reached yet since most patients receive second-line therapy. Grade (Gr) 3/4 toxicities included: neutropenia 18/32 (56%)-with 11 developing Gr4 (≤7 days) and 19% of patients at least one episode of febrile neutropenia managed successfully by broad spectrum antibiotics, thrombocytopenia Gr3: 5/32 (16%) and Gr4 3/32 (9%), no Gr3 neuropathy, Gr1 CNS toxicity in 1, no renal toxicity, 15 Gr2 myalgias, and 4 Gr3 vomiting. Conclusions: In the present study, it appears that the TICb combination, yielded important activity with acceptable toxicity in females with advanced MMMTs. No significant financial relationships to disclose.

Abstract
PURPOSE This phase II pilot study was conducted to evaluate the results of a three-modality approach (which included post-chemoradiotherapy surgery) in advanced-stage cervical carcinomas. PATIENTS AND METHODS Thirty-six patients underwent either surgery or were put on follow-up after having received radical cervical radiotherapy (RT) combined with radiosensitizing chemoimmunotherapy with irinotecan (CPT-11), interferon (IFN) A2b, and amifostine. The last selection (surgery or follow-up) was based on clinical evaluation (downstaged or not). Feasibility, morbidity, surgical outcome and survival were evaluated. RESULTS Twenty-six patients had stage IIb and 10 IIIb disease at diagnosis. Sixteen (44%) were clinically downstaged, thus becoming eligible for surgery. Twelve (33%) were operated and the others were put on follow-up. There was no significant increase in treatment-related morbidity of the group of patients receiving three-modality therapy, since only one intraoperative complication had occurred. In 58% of the operated patients, chemoradiotherapy-resistant tumor was found on pathology of the cervical specimens, while 29% of them had lymph nodes infiltrated by the tumor. After a median follow-up of 42.5 months, overall survival (OS) of operated vs. non-operated patients (88 vs. 56%, respectively) show only a trend toward significance (p=0.10). The overall recurrence/metastasis rate was 36.1% and the disease-free survival (DFS) 56% for operated vs. 76% for non-operated patients, respectively (p=0.63). CONCLUSION These results indicate that post-chemoradiotherapy surgery is justified because of the high rate of residual disease found. Morbidity can be effectively limited with proper patient selection. A considerable survival benefit is expected, although this remains to be confirmed with phase III studies.

Abstract
Agricultural soil erosion is thought to perturb the global carbon cycle, but estimates of its effect range from a source of 1 petagram per year(-1) to a sink of the same magnitude. By using caesium-137 and carbon inventory measurements from a large-scale survey, we found consistent evidence for an erosion-induced sink of atmospheric carbon equivalent to approximately 26% of the carbon transported by erosion. Based on this relationship, we estimated a global carbon sink of 0.12 (range 0.06 to 0.27) petagrams of carbon per year(-1) resulting from erosion in the world's agricultural landscapes. Our analysis directly challenges the view that agricultural erosion represents an important source or sink for atmospheric CO2.

Abstract
Over the last few years it has been anticipated that molecularly targeted agents can provide substantial improvement in the treatment of breast cancer. The most illustrative paradigm has been that of trastuzumab (Herceptin), a humanized monoclonal antibody against the HER2 oncoprotein overexpressed in 25% of breast cancers. Trastuzumab when combined with standard cytotoxic chemotherapy improved the outcome and survival in patients with metastatic breast cancer, whereas, over the last 2 years studies incorporating trastuzumab in sequence to or concurrently with taxane-based chemotherapy in the adjuvant setting demonstrated a considerable benefi t in this subset, with the results of longer follow-up regarding long-term outcome and late toxicities expected over the forthcoming years. Moreover, the prognostic and predictive value of topoisomerase IIa (Topo IIa) overexpression in these subgroups with respect to anthracycline treatment has been extensively discussed and analysed. Other inhibitors of both HER1/HER2 have recently been introduced with promising results and results of ongoing studies are awaited with great interest. A recently anticipated target in advanced breast cancer has been the pathway of angiogenesis; first a humanized monoclonal antibody-bevacizumab (Avastin)- has demonstrated encouraging results when combined with chemotherapy in pretreated HER2-negative advanced breast cancer, while combinations with trastuzumab+/-chemotherapy are currently examined in HER2-overexpressing breast cancer. Furthermore, as novel molecular pathways relevant to breast cancer biology are explored, it is expected that a whole array of targeted agents will be tested in combination or in sequence to standard chemotherapy with the aim to improve outcome of high-risk breast cancer patients.

Abstract
Aplastic anemia is a rare immune-mediated complication of thymoma. Thymomas, especially of the cortical type, have the capacity to generate mature T-cells from their immature precursors. Furthermore, mature intratumorous T-cells have an increased autoantigen-specific potential. We present the case of a 75-year-old patient with an inoperable cortical thymoma who developed aplastic anemia 7 years after the initial diagnosis. The infiltration of the bone marrow by these cells was accompanied by the production of cytokines such as tumor necrosis factor alpha (TNF-alpha) in the microenvironment of bone marrow and in the serum sample. The patient was successfully treated with oral cyclosporine A for 14 months and when she died due to progression of the thymoma, 9 months after the discontinuation of cyclosporine, the aplastic anemia had not recurred.

Abstract
10663 Background: Addition of trastuzumab (Herceptin, H) to successive neoadjuvant taxane+anthracycline-based chemo in patients (pts) with HER-2 (+) breast cancer significantly increases the pathological complete response (CR) rates. PLD has considerably less cardiotoxicity compared to parent drug. The aim of the study was to evaluate the activity and safety of combining H with PLD and P as 1st-line chemo in HER-2 (+) MBC pts. Methods: Inclusion criteria were: histologically confirmed MBC or relapsed after adjuvant chemo, ≥1 measurable lesion, adequate organ function, ECOG-PS 0–1, left ventricular ejection fraction (LVEF) by MUGA ≥55% (reevaluated after cycles 3 and 6). HER-2 positivity was determined by IHC and confirmed with CISH. Chemo was administered as follows: H 6mg/kg (8mg/kg-1st cycle) infused over 90min, PLD 35mg/m2 over 1hr, and P 175mg/m2 over 3hrs on day 1, with prophylactic G-CSF, recycled every 3 weeks. In responders, H was administered as consolidation (6mg/kg/3wks) until disease progression. Results: From 10/2003–10/2005, 19 female HER-2 positive MBC pts were enrolled. Median age: 68 (range, 42–78). Metastatic sites were: lung 6, liver 1, bone 3, lymph nodes 11, soft tissue 5 [median: 2 (range, 1–4)]. Pts received a median of 6 (range, 1–8) for a total of 102 cycles. PLD was started at 35 mg/m2, but in pts with grade 3 hand-foot syndrome (HFS) dose was reduced by 25% (6 pts), or the drug was omitted for 1 cycle (1 pt). 17 pts completed 3–6 cycles and were evaluable for response, all treated patients were evaluable for toxicity. Response rates (RR) were 71%; CR 41%, PR 30%, SD 29%, with no PD. Two pts rendered operable had pCR. Toxicities were: HFS; grade 4: 1, grade 3: 6 (overall 37%), grade 3–4 neutropenia: 4, grade 3 anemia: 1, grade 3–4 mucositis: 2, and grade 2 alopecia: 19. Neither significant LVEF decline, nor symptomatic cardiac event was observed. It is too early to provide data on response duration, TTP, and OS, and these will be available at the meeting. Conclusions: H+P+PLD as 1st-line chemo in HER-2(+) MBC pts is a very active and well tolerated regimen with no significant morbidity/mortality. HFS was the most relevant toxicity. The study is ongoing. No significant financial relationships to disclose.

Abstract
PURPOSE To evaluate the effectiveness of 6-month therapy with leucovorin (LV)+5-fluorouracil (5-FU) versus 12-month therapy with levamisole (LVS)+5-FU, as adjuvant chemotherapy in patients with completely resected Aster-Coller stage B(2) or C(1)/C(2) rectal cancer (RC). PATIENTS AND METHODS One hundred and fifty patients with surgically resected RC were enrolled. Seventy patients with stage B(2) and 80 with stage C were randomly assigned to adjuvant chemotherapy with 5-FU+LXx6 months or 5-FU+LVSx12 months. Patient characteristics were equally balanced between the examined groups. Adjuvant chemotherapy consisted of LV 20 mg/m(2) intravenously (i.v.) plus 5-FU 450 mg/m(2) i.v. bolus every week plus LVS tablets 50 mg t.i.dx3 days every 2 weeks for 1 year. RESULTS After a median follow up for survivors of 8.7 years (range 1.8-10.5), all of the patients were evaluable. There were no significant differences between the two treatment groups with respect to the recurrence rates (p=0.821). Moreover, there were no significant differences between the two tratment groups in disease-free survival (DFS) (p=0.84) [B(2)(p=0.805) and C (p=0.978)] and overall survival (OS) rates for patients of either stage B(2) or C (p=0.78). Toxicities were more frequent in the 5-FU+LVS versus 5-FU+LV group: myelosuppression (grade 3 leucopenia, 12 versus 4%, p<0.04), diarrhea (grade 0, 60 versus 76%, p<0.02), and liver toxicity (increase of transaminases >3-fold, 12 patients versus 2, p<0.03.). No patient stopped chemotherapy because of toxicity, and there were no treatment-related deaths. CONCLUSION Adjuvant chemotherapy in RC with LV+5-FU for 6 months is equally effective and less toxic than LVS+5-FU for 12 months.

Abstract
The present phase II study aimed to define the application of a novel regimen incorporating methotrexate, paclitaxel, epirubicin, and carboplatin (M-TEC) in advanced bladder cancer, essentially as an M-VAC-like regimen, by substitution of cisplatin by carboplatin, doxorubicin by epirubicin and vinblastine by paclitaxel. Forty patients with advanced bladder cancer entered the study; 34 males/6 females, median age: 68 (range, 59-76), median PS (Karnovsky): 80, without receiving prior chemotherapy. Disease extention was as follows; 11/40 had local recurrence, 6/40 liver metastases, 14/40 lung metastases, bone and lymph node 8/40, bones-lymph node-lung metastases 4, lymph node and liver 4/40, lymph node-liver and lung metastases 2/40. Drug schedule and doses were as follows: paclitaxel 180 mg/m2, carboplatin AUC = 5 (according to creatinine clearance, based on Calvert's formula), and epirubicin 40 mg/m2 were administered during day 1, whereas methotrexate 30 mg/m2 and epirubicin 40 mg/m2 were administered on day 14. All patients were evaluable for response with 24/40 responding [response rate (RR) 60%]; 10/40 (25%) CR, 14/40 (35%) PR, 9/40 (22.5%) SD, and 7/40 (17.5%) PD. Symptomatic improvement was observed in 50% of patients. The median duration of response was 22 (14-32) weeks, median time-to-progression (TTP) 33 (12-44) weeks, and median survival was 56 (20-84) weeks. Toxicity was well accepted and was mainly neutropenia > grade 3: 17%, anemia >grade 3: 16%, thrombocytopenia > grade 2: 6%, nausea & vomiting mainly > grade 2: 31%, according to the administered chemotherapy cycles, whereas fatigue grade 2-3: 19%, neurotoxicity grade 1-2 13% of patients, and alopecia grade 2 was observed in all patients. The present pilot study indicates the feasibility of the M-TEC combination for bladder cancer with acceptable toxicity.

Abstract
PURPOSE Cardiotoxicity associated with 5-fluorouracil (5FU) administration is infrequently reported in the literature, albeit case reports of acute coronary syndromes have been published. In the present study, patients undergoing 5FU chemotherapy were tested for the development of cardiac-related symptoms during its administration. PATIENTS AND METHODS Five hundred twenty-two patients entered the study. Those experiencing any cardiac-related symptoms during 5FU infusion were subjected to electrocardiogram (ECG) and serum cardiac enzymes determination. If cardiotoxicity was confirmed, 5FU infusion was interrupted, sublingual nitrates administered and cardiac monitoring initiated, while patients with >2-fold enzyme elevation were admitted into a coronary care unit for at least 72 hours. Cases with acute myocardial infarction had to discontinue 5FU treatment. RESULTS Overall 20 (3.8%) patients developed symptoms and/or ECG abnormalities due to 5FU. Patients with continuous 5FU infusion had a trend for higher incidence of cardiotoxicity (13/205, 6.3%) than the remaining (7/317, 2.2%; p=0.067). More specifically, increased toxicity was encountered in patients with continuous 24 h 5FU+ leucovorin (LV) infusion for 5 days compared to patients with the same schedule without LV (p <0.027) and patients with short 5FU+LV administration as well (p=0.024). Seven out of the 20 patients suffered acute myocardial infarction, 6 developed only ischemia, while ECG findings consistent with coronary vasospasm were detected in 4 patients and conduction disturbances in 3 patients (one subsequently died). CONCLUSION The present study indicates a toxic effect of 5FU on myocardium, which is largely schedule-dependent. High level of alert is required when using this drug, while its toxic effect on the coronary endothelium and myocardium merits further investigation.

Abstract
PURPOSE To investigate the overall survival (OS) of patients developing breast cancer (BC) after curative chemotherapy for non-Hodgkin's lymphoma (NHL) and to evaluate the possible effect on the patients' outcome of the expression of drug resistance-related proteins (P-glycoprotein-Pgp, multidrug resistance-associated protein-MRP, and multidrug resistance-related vault lung resistance protein-LRP) in BC issue. PATIENTS AND METHODS STUDY GROUP 25 female patients (median age 60 years, range 37-70) who developed BC after chemotherapy for high/intermediate grade B-cell NHL, treated with CHOP and achieving complete remission (CR). This group was further subdivided in subgroups A and B, according to the time interval between NHL and BC development (</=24 and > 24 months, respectively). A matched-pair group of de novo BC patients formed the control group. BC tissue was immuno-histochemically stained for Pgp, MRP and LRP. RESULTS The median interval between NHL diagnosis and BC development was 26 months (range 9-49). In both groups 14 patients had tumor grade II; 16 were negative for steroid receptors; 17 overexpressed c-erbB-2; 14 were stage IIIA/B, and 11 stage IV. CMF or CNF (mitoxantrone instead of doxorubicin) were given for BC. Early progression was noticed in all study group patients for which second-line chemotherapy was instituted. There was a better response for stage IV patients in the control versus the study group (p=0.07). More prolonged OS was demonstrate for patients with stage III in the control group (median 51 months) and in subgroup B (median 47 months) than in subgroup A (median 16 months; p=0.00012), as well as for patients with advanced disease (p=0.0045). Development of BC < 24 months after NHL resulted in reduced OS (p=0.017). No difference was noticed in the expression of drug resistance proteins between the study and control group or between subgroups A and B. CONCLUSION BC developing shortly after a CR to NHL is an aggressive disease variant with minimal potential for response to conventional chemotherapy. Analysis of Pgp, MRP and LRP failed to demonstrate significant difference between the study and control group, although indications exist that drug resistance mechanisms might be part of the aggressive disease phenotype, contributing to the poor outcome.

Abstract
We examined the outcome of patients who developed breast cancer after curative chemotherapy (CHOP) for aggressive non-Hodgkin's lymphoma (NHL) in comparison to the outcome of a retrospectively selected matched-pair group of patients with de novo breast cancer, and evaluated the role of drug resistance-related protein (MDR, MRP, LRP) expression in breast cancer tissue. Twenty-two patients presented with breast cancer (BC) in complete remission after CHOP for NHL. The median age was 62 (49-70) years, each had high/intermediate grade B-cell NHL treated with 6 courses of CHOP, and were in complete remission. These patients were compared to a matched-pair group of de novo BC patients selected from our database over the same time period. Breast cancer tissue was stained by immunohistochemistry for drug resistance proteins LRP, MRP, and MDR. Breast cancer developed after a median of 26 (9-49) months of NHL diagnosis; breast tumor grades 1-2 were seen in 12, and grade 3 in 10 patients; 15 were negative and 7 weakly positive for estrogen and progesterone receptors. Twelve patients were stage IIIA/B, and 10 stage IV and were treated with conventional chemotherapy regimens. All progressed early in liver (n=13), brain (n=9), lung (n=6), bone (n=8), lymph nodes (n=7) and soft tissue (n=5), and received second-line chemotherapy with mitomycin-C + vinblastine or taxanes. The overall survival was 11.8 (6-26) months (p<0.01). Time from NHL to breast cancer development was 19 (14-27) months in patients with positive drug resistance proteins (group A), and 37 (26-56) months in patients with 1 or 2 positive resistance proteins (group B) (p<0.001). In patients with stage IIIA/B disease, there was no difference between the examined and control matched-pair group in median TTP, but there was in overall survival (OS) (23 vs 36 months, p=0.029). In advanced disease, there were more responders in the control vs the examined group (p=0.07). Patients in the control matched-pair group had more prolonged OS when compared to group A patients who developed BC in <24 months from NHL to BC (p=0.017). We conclude that breast cancer developing shortly after a complete response in NHL, is an aggressive disease variant with minimal potential for response to conventional chemotherapy. Analysis of drug resistance mechanisms concerning MDR, MRP and LRP indicates that most of these patients have BC that overexpress these proteins leading to the suggestion that these mechanisms might be a part of the aggressive disease phenotype and partially explain the poor outcome.

Abstract
The aim of this study was to evaluate the effectiveness of 6-month therapy with leucovorin (LV) + 5-fluorouracil (5-FU) vs 12 months of therapy with levamisole (LVZ) + 5-FU, as adjuvant chemotherapy in patients with completely resected Dukes' stage B2 or C rectal cancer. One hundred and fifty patients with surgically resected rectal carcinoma, were enrolled in the present study; Dukes' stage B2 (n=70) or C (n=80), were randomly assigned to chemotherapy with 5-FU + LV x 6 months or 5-FU + LVZ x 12 months. Patient characteristics were equally balanced between the examined groups. Adjuvant CT consisted of LV 20 mg/m(2) intravenously (i.v.) plus 5-FU 450 mg/m(2) i.v., on days 1-5 every 4 weeks for 6 cycles or 5-FU 450 mg/m(2) i.v. every week plus LVZ 50 mg t.i.d x 3 days for 1 year. All patients received radiotherapy with a three-field technique to a total dose of 45 Gy, over 5 weeks. After a median follow-up of 7.4 years there were no significant differences between the two treatment groups with respect to the recurrence rates (P=0.821). Moreover, there was no difference in disease-free survival for patients stage Dukes' B2 (log-rank p=0.73); median for LV group 90 (8-131) months, and for LVZ group 86.5 (3-129) months. No difference was noted in disease-free survival for patients stage Dukes' C (log-rank p=0.73); median for LV group 60 (17-128) months, and for LVZ group 64 (2-123) months. There was no difference in overall survival for patients stage Dukes' B2 (log-rank p=0.75); median for LV group 90 (22-131) months, and for LVZ group 86 (10-129) months. For stage Dukes' C (log-rank p=0.73); median for LV group 67 (17-128) months, and for LVZ group 64 (5-123) months. Toxicities were as follows in the 5-FU + LVZ vs 5-FU + LV group; myelosuppression (leucopenia grade 3, 12% vs 4%, p<0.04), diarrhea (grade 0, 60% vs 76%, p<0.02), and liver toxicity (increase of transaminases >3-fold, 12 patients vs 2, p<0.03), were more frequent in LVZ group. None of the patients stopped chemotherapy because of the toxicity, and there were no toxicity-related deaths. In conclusion, adjuvant chemotherapy in RC with LV + 5-FU for 6 months is equally effective and less toxic than LVZ + 5-FU for 12 months.

Abstract
PURPOSE To evaluate the efficacy and safety of irinotecan as second-line treatment in patients with advanced colorectal cancer (ACC) failing or relapsing after 5-fluorouracil (5-FU) plus leucovorin (LV) standard chemotherapy. PATIENTS AND METHODS Irinotecan was randomly administered in two different schedules (once every 3 weeks, and every 10 days) in patients failing prior 5-FU plus LV. Patients were randomized to two treatment groups: group A received irinotecan 350 mg/m2 every 21 days and group B received irinotecan 175 mg/m2 days 1 and 10 every 21 days. RESULTS Group A comprised 60 patients: 34 male/26 female, median age 64 years (range 48-70 years), and median Karnofsky performance status (PS) 90. Their metastatic sites included liver (n=47), lymph nodes (n=27), lung (n=14), abdomen (n=14), pelvis (n=8), "other" (n=2), and local recurrence (n=12). Group B comprised 60 patients: 36 male/24 female, median age 62 years (46-70 years), and median PS 90. Their metastatic sites included liver (n=49), lymph nodes (n=29), lung (n=17), abdomen (n=16), pelvis (n=11), "other" (n=2), and local recurrence (n=13). Group A showed the following responses: complete response (CR) 2, partial response (PR) 12, stable disease (SD) 21, progressive disease (PD) 26, overall response rate (ORR) 23%, tumor growth control 58%. Group B showed the following responses: CR 1, PR 14, SD 22, PD 23; ORR 25%; tumor growth control 62%. Toxicities included acute cholinergic syndrome (group A 53%, group B 19%; P<0.0001), late-onset diarrhea grade 1/2 (group A 21%, group B 46%) and grade 3/4 (group A 41%, group B 66%; P<0.0001), nausea and vomiting grade 1/2 (group A 34%, group B 59%) and grade 3/4 (group A 30%, group B 12%; P<0.0001), neutropenia grade 3/4 (group A 27%, group B 28%; P<0.03), with febrile neutropenia seen in only four patients in group A, anemia grade more than 2 (group A 28%, group B 12%; P<0.05), asthenia grade more than 3 (group A 24%, group B 18%; P<0.001), and alopecia grade more than 3 (group A 40%, group B 34%; P<0.2). CONCLUSIONS . The present study indicates that, in patients with ACC who have relapsed after 5-FU plus LV, the administration of irinotecan fractionated into two doses every 21 days yields a similar efficacy to, but a much lower incidence of toxicity than, the same total dose of irinotecan administered once every 21 days.

Abstract
We investigated the efficacy of Mo17-1A to improve important immunological parameters in vivo and in vitro in colorectal cancer (CRC) patients receiving no second-line treatment. Eighteen CRC patients stage Dukes' C were treated postoperatively with 5 doses of Mo17-1A. Peripheral blood mononuclear cells (PBMC) were analyzed for proliferative responses and cytolytic activity. Serum levels of cytokines were determined during treatment. Enhancement in the proliferative activity of patients' T cells, improvement in their lymphocytes' killing ability of natural killer (NK) and lymphokine-activated killer (LAK) sensitive tumor targets, and an in vivo increase in serum levels of interleukin (IL)-2, IL-12, IL-15, interferon (IFN)-gamma and granulocyte-macrophage colony-stimulating factor (GM-CSF) were noted. We conclude that treatment of CRC patients with Mo17-1A partially restores deficient cellular immune responses and the secretion of cytokines with immuno-enhancing properties. The development of novel immunotherapeutic protocols using combinations of Mo17-1A with stimuli that enhance the lytic capacity of effector cells (e.g. cytokines), may improve clinical responses in these types of patients.

Abstract
Given the established individual activity of docetaxel and ifosfamide in anthracycline pretreated advanced breast cancer, the present phase I-II study aimed to define the maximum tolerated dose (MTD), the dose-limiting toxicities (DLTs), and activity of the docetaxel-ifosfamide combination in this setting. Cohorts of three to six patients with histologically confirmed metastatic breast cancer after prior anthracycline-based chemotherapy were treated at successive dose levels (DLs) with escalated doses of docetaxel 70-100 mg x m(-2) over 1 h on day 1 followed by ifosfamide 5-6 g x m(-2) divided over days 1 and 2 (2.5-3.0 g x m(-2) day(-1) over 1 h), and recycled every 21 days. G-CSF was added once dose-limiting neutropenia was encountered at a certain DL and planned to be incorporated prophylactically in subsequent higher DLs. In total, 56 patients with a median age of 54.5 (range, 32-72) years and performance status (WHO) of 1 (range, 0-2) were treated at five DLs as follows: 21 in phase I DLs (DL1: 3, DL2: 6, DL3: 3, DL4: 6, and DL5: 3) and the remaining 35 were treated at DL4 (total of 41 patients at DL4), which was defined as the level for phase II testing. All patients were assessable for toxicity and 53 for response. Dose-limiting toxicity (with the addition of G-CSF after DL2) was reached at DL5 with two out of three initial patients developing febrile neutropenia (FN). Clinical response rates, on an intention-to-treat basis, in phase II were: 53.6% (95% CI, 38.3-68.9%); three complete remissions, 19 partial remissions, seven stable disease, and 12 progressive disease. The median response duration was 7 months (3-24 months), median time to progression 6.5 month (0.1-26 month), and median overall survival 13 months (0.1-33 months). Grade 3/4 toxicities included time to progression neutropenia in 78% of patients-with 63% developing grade 4 neutropenia (<or=7 days) and in 12% of these FN, while no grade 3/4 thrombocytopenia was observed. Other toxicities included peripheral neuropathy grade 2 only in 12%, grade 1/2 reversible CNS toxicity in 17%, no renal toxicity, grade 2 myalgias in 10%, grade 3 diarrhoea in 10%, skin/nail toxicity in 17%, and grade 2 fluid retention in 2% of patients. One patient in the study treated at phase II died as a result of acute liver failure after the first cycle. In conclusion, the present phase I-II study determined the feasibility of the docetaxel-ifosfamide combination, defined the MTD and demonstrated the encouraging activity of the regimen in phase II, thus warranting further randomised phase III comparisons to single-agent docetaxel or combinations of the latter with other active agents.

Abstract
BACKGROUND The purpose of this study was to evaluate the efficacy and toxicity of oxaliplatin plus 5-fluorouracil (5-FU) and leucovorin (LV) in patients with metastatic breast cancer (MBC) previously treated with anthracyclines and taxanes. PATIENTS AND METHODS Fifty anthracycline- and taxane-pretreated MBC patients were treated with oxaliplatin 85 mg/m(2) as a 2-h infusion on day 1, LV 200 mg/m(2)/day as a 2-h infusion followed by bolus 5-FU 400 mg/m(2)/day and a 22-h infusion of 5-FU 600 mg/m(2)/day for 2 consecutive days. Treatment was repeated every 3 weeks. Patients were evaluated for response every two cycles. RESULTS The median age was 51 years (range 34-75). Twenty patients (40%) had received three or more chemotherapeutic regimens, 64% had three or four metastatic sites and 78% had visceral metastases. All patients had prior exposure to anthracyclines and taxanes. Based on an intention-to-treat analysis, one patient (2%) achieved a complete response and 16 (32%) a partial response, for a 34% overall response rate. Twenty-one patients (42%) had stable disease and 12 (24%) progressive disease. The median time to tumor progression was 5.3 months (range 0.5-12.8) and the median overall survival was 12.3 months (range 0.5-19.2). Toxicity was mild to moderate. Grade 3/4 neutropenia and thrombocytopenia occurred in 32% and 18%, respectively. Febrile neutropenia was experienced by three patients (6%), who were successfully treated. Grade 3/4 neurotoxicity was reported in 14% of the patients and gradually declined after treatment discontinuation. Cycle delays were reported in 28% of patients and dose reductions in 26%. Alopecia, nausea-vomiting, diarrhea and mucositis were not significant. There were no treatment-related deaths. CONCLUSION The combination of oxaliplatin plus 5-FU/LV seems to be an active regimen in patients with MBC and prior exposure to anthracyclines and taxanes with a good safety profile. The incidence of severe toxicity was quite low and the compliance of patients to the treatment was satisfactory. The results obtained with this regimen could be considered encouraging in this heavily pretreated group of breast cancer patients with a high incidence of visceral metastases.

Abstract
We describe a case of synchronous splenic marginal zone-cell lymphoma (SMZL) and T-cell large granular lymphocyte leukemia involving the spleen, liver, bone marrow and peripheral blood. The synchronous occurrence of these two processes was documented by morphological, immunophenotypical and molecular (PCR) analyses of all affected tissues. The pathogenetic mechanisms which may be responsible for the concomitant appearance of these two rather infrequent entities in the same anatomic sites are discussed.

Abstract
Intramedullary spinal cord metastases (ISCM) are usually the result of rapidly progressing systemic malignancy. Breast cancer is one of the most common solid tumors with a high propensity of CNS dissemination. In the present report we describe two new cases with advanced breast cancer developing ISCM after a variable disease course. One of these patients had brain metastases at presentation, while at relapse developed leptomeningeal carcinomatosis which was treated successfully, but followed shortly, as a terminal event, by ISCM and parenchymal brain recurrence. The other patient was treated initially for locally advanced breast cancer and after multiple locoregional relapses, she developed liver metastases and subsequent ISCM and asymptomatic parenchymal brain deposits. Both patients experienced a rather rapidly evolving disease course leading to death 2 and 4 months, respectively, after widespread neuraxis dissemination of their cancer. Both these cases, added to the list of the anecdotally reported cases of ISCM after breast cancer, undermine the ominous prognosis and limited treatment options available for this disease manifestation, and an extensive literature review and discussion of similar cases is provided.

Abstract
Over the last 5 years, studies applying the chimeric anti-CD20 MAb have renewed enthusiasm and triggered world-wide application of anti-CD20 MAb-based therapies in B cell non-Hodgkin's lymphoma (NHL). Native chimeric anti-CD20 and isotope-labeled murine anti-CD20 MAbs are currently employed with encouraging results as monotherapy or in combination with conventional chemotherapy and in consolidation of remission after treatments with curative intent (ie after/ in combination with high-dose chemotherapy and hematopoietic stem cell rescue). On the available experience, anti-CD20 MAb-based therapeutic strategies will be increasingly integrated in the treatment of B cell NHL and related malignancies.

Abstract
In the present study, we evaluated the efficacy and safety of the weekly combination of etoposide, leucovorin (LV) and 5-fluorouracil (5-FU) when administered as second-line chemotherapy in patients with relapsed/refractory advanced colorectal cancer (ACC), previously treated with weekly LV+5-FU. Etoposide was administered at 3 different dose levels (DLs), in 3 groups of 20 patients each (total: 60); DL-I: etoposide 80 mg/m2, DL-II: etoposide 120 mg/m2, and DL-III: etoposide 180 mg/m2, in 45 min i.v. infusion, and followed in all levels by LV 100 mg/m2 i.v. over 1 hour and 5-FU 500 mg/m2 i.v. bolus. Treatment was administered weekly until disease progression or unacceptable toxicity. No patients at DL-I responded, while 2 patients at DL-II and 3 at DL-III had a partial response (PR). Stable disease (SD) rates were as follows; at DL-I: 2, DL-II: 8 and DL-III: 9. More patients in DL-I progressed (n = 19) compared to DL-II (n=10) and DL-II (n = 8) (p < 0.0007). Time to progression was for DL-I, -II, -III: 17, 15, and 14 weeks, respectively. Median survival was DL-I, -II, -III: 30, 30, and 32.5 weeks, respectively. Toxicity consisted mainly of neutropenia, diarrhea and mucositis at all DLs, and was significantly more severe in DL-III. No difference was noted in responses between DL-II and DL-III. The authors conclude that the combination of etoposide with LV+5-FU has limited activity when administered after failure of weekly LV+5-FU in patients with ACC and should not be recommended for further evaluation.

Abstract
Besides cytotoxicity, taxanes induce other biological effects, especially in the immune system. Taxanes have demonstrated immunostimulatory effects against neoplasms, supporting the idea that these agents suppress cancer through several mechanisms and not solely through inhibiting cell division. The purpose of the present study was to evaluate the effect of taxanes (paclitaxel and docetaxel) and investigate their ability in alterating important immunological parameters in breast cancer patients. Thirty women with advanced breast cancer undergoing chemotherapy were randomly assigned into two groups treated with either single agent Paclitaxel or Docetaxel. Sera from patients before the first and after the last treatment cycle and from normal donors were assayed by ELISA for IL-2, IL-1beta, IFN-gamma, GM-CSF, IL-6, TNF-alpha, and PGE2 levels. In these same blood samples, NK and LAK cell activity was tested in the total PBMC population against NK-sensitive K562 tumour targets, respectively, and autologous mixed lymphocyte reaction was tested by (3)H-thymidine proliferation assays. All patients in both groups responded to therapy. Significant differences were observed in the following immune parameters between the control group of healthy blood donors and the pretreatment values of both taxane groups; IL-2, GM-CSF, IFN-gamma levels and NK and LAK cell cytotoxicity were depressed, whereas TNF-alpha and IL-6 levels were raised in breast cancer patients before treatment compared to controls. There were no significant differences between the two treatment groups regarding any of the parameters studied. Both drugs led to increases in MLR values, NK and LAK cell cytotoxicity, and IL-6, GM-CSF, IFN-gamma levels, and decreases for IL-1, TNF, and PGE2 levels. The percentage of these differences was greater for docetaxel in comparison to paclitaxel (P<0.0001). More specifically, docetaxel demonstrated a more pronounced effect on enhancing MLR, NK, LAK activity and IFN-gamma, IL-2, IL-6, and GM-CSF levels, as well as caused more potent reduction in IL-1 and TNF-alpha levels when compared to paclitaxel. The present study indicates that patients responded to treatment of advanced breast cancer with single-agent paclitaxel or docetaxel leads to an increase in serum IFN-gamma, IL-2, IL-6, GM-CSF cytokine levels and enhancement of PBMC NK and LAK cell activity, while they both lead to a decrease of acute phase serum cytokine levels of IL-1 and TNF-alpha. Moreover, the effects of docetaxel are in all the above parameters more pronounced than those of paclitaxel.

Abstract
AIM To define the maximum tolerated dose (MTD) and the dose-limiting toxicities (DLTs) of the carboplatin-vinorelbine combination in pretreated patients with advanced breast cancer. PATIENTS AND METHODS Patients with histologically confirmed metastatic breast cancer relapsing or progressing after prior taxane and anthracycline containing chemotherapy were enrolled. Cohorts of 3-6 patients were treated at successive dose levels (DLs) with escalated doses of carboplatin [range, area under the curve (AUC) 4-6] on day 1 and vinorelbine (range, 20-35 mg/m(2)) on days 1 + 8 recycled every 28 days. RESULTS Twenty-seven patients with a median age of 58 years and performance status (WHO) of 0-2 were treated at 6 DLs. All patients were assessable for toxicity and 20 for response. DLT was reached at carboplatin 6 AUC and vinorelbine 35 mg/m(2), and therefore, this was considered as the MTD. Prophylactic G-CSF administration could not allow further dose escalation. The recommended dose for further phase II testing was defined at carboplatin 6 AUC on day 1 and vinorelbine 30 mg/m(2) on days 1 and 8. Among 98 administered treatment cycles 41 (42%) and 7 (7%) were complicated with grades 3 and 4 neutropenia and thrombocytopenia, respectively. Nonhematologic toxicities included grade 2 peripheral neuropathy in 3 cycles and grades 2 and 3 fatigue in 32 (32%). CONCLUSION The present study determined the feasibility of the combination of carboplatin at AUC 6 (day 1) and vinorelbine at 30 mg/m(2) (days 1 and 8 ) without G-CSF support in patients with taxane and anthracycline pretreated advanced breast cancer. Phase II studies at these doses should follow in order to determine the activity of the regimen.

Abstract
A 37-yr-old man who had undergone renal transplantation for end-stage renal failure presented with a large right pelvic mass obstructing the transplanted kidney. Initially, this was diagnosed as an anaplastic tumor while he had been on immunosuppressive treatment for kidney allograft rejection after transplantation. Despite difficulties of classic histopathology to reveal the origin of his tumor, FISH analysis revealed the presence of chromosome 12p abnormalities, strongly indicative of a germ-cell tumor-more likely seminoma-with extragonadal presentation. Because of renal dysfunction, he was treated with carboplatin (dose adjusted according to renal clearance) and etoposide, and when he experienced a rather atypical progression with bone metastases, he was treated with single-agent paclitaxel, and died almost 13 mo after initial presentation. The case adds further to the existing small list of seminoma/GCTs developing in transplant recipients, points to the unusual presentation patterns and diagnostic histopathology challenges, and presents the difficulty in therapeutic options, as a result of frequent renal dysfunction and intercurrent immunosuppressive therapy. All of these issues together with an extensive literature review are discussed in detail.

Abstract
The relationship between polymyositis and malignancy is well known. Several types of tumors can be complicated with myositis and/or more frequently dermatomyositis. It has been suggested that tumors of the large bowel are rarely complicated by myositis. We describe a patient with adenocarcinoma of the colon presenting as polymyositis and review the available literature.

Abstract
PURPOSE To evaluate efficacy of Raltitrexed, a specific thymidilate synthase inhibitor, in patients with advanced colorectal cancer (ACC) failing multiple prior chemotherapy regimens (e.g. 5-FU+LV, CPT-11, etc). METHODS 20 patients with ACC; 13 males/7 females, median age 64 (range: 53-69), median Karnovsky PS: 80 (70-90), and sites of metastases; liver: 16, lung: 6, lymph nodes: 9, peritoneal: 8 and a life expectancy of at least 3 months, were entered in the present pilot study of Raltitrexed administration. All patients had progressed after prior chemotherapy with 5-FU+LV and subsequently CPT-11, and some had received further infusional 5-FU, Raltitrexed was administered at a dose of 3 mg/m2 i.v. every 21 days. RESULTS 3 patients obtained stable disease (SID), 15%, with tumor marker decline (CEA, CA-19.9). Time-to-progression was 4.8 months (2.2-7) and survival 7.4 months (6.0-7.8). Toxicity was in general not severe and consisted mainly of myelosuppression; neutropenia (WHO) grade 2: 45% and grade 3: 22%, and anemia grade 1-2: 40%. CONCLUSION Response to treatment with Raltitrexed is limited in patients with ACC failing multiple prior chemotherapy regimens, however, a limited percentage of patients with SD derived clinical benefit.

Abstract
We have retrospectively evaluated and characterized the hypersensitivity reactions associated with carboplatin administration in ovarian cancer patients treated mainly on an outpatient basis at the Laikon Hospital from 1988 to 1998. A total of 240 patients, who had never been exposed to platinum compounds previously, received carboplatin plus cyclophosphamide (n = 58) or paclitaxel (n = 136) intravenously, and intraperitoneal carboplatin plus intravenous cyclophosphamide (n = 46). The median number of carboplatin courses was 6 (range 3-12) and 5 (range 4-6) for the intravenous and intraperitoneal treatment regimens, respectively. Thirty-two of 194 patients (16%) who were on intravenous carboplatin treatment developed symptoms compatible with a hypersensitivity reaction to carboplatin, that was always verified by manifestation of at least similar symptoms on rechallenging. In contrast, in the group of 46 patients on intraperitoneal carboplatin treatment, no hypersensitivity reaction was ever noticed. Hypersensitivity reactions always occurred after administration of the first 4 intravenous courses of carboplatin; 4, 19, 4, and 5 reactions occurred at the 5th, 6th, 7th, and 8th courses, respectively. These reactions could be distinguished in: (a) mild hypersensitivity reactions in 20 of 194 patients, which manifested as itching (20 patients) and small area erythema plus erythema of the palms and soles (12 patients), occurring either during intravenous injection when most of the drug scheduled had been administered, or within 3 days, and (b) in severe reactions in 12 of 194 patients, which manifested acutely as itching, diffuse erythroderma, rigor, facial swelling, throat and chest tightness, tachycardia (12 patients) and bronchospasm (2 patients), and hypertension or hypotension in 8 and 4 patients, respectively. With appropriate symptomatic management, discontinuation of carboplatin treatment was not required in patients with mild hypersensitivity reactions, but none of the 12 patients with severe reactions was able to receive a full subsequent dose of carboplatin on rechallenging. However, in 4 of these 12 patients carboplatin was replaced by cisplatin, which was given for 4-6 courses without side effects. These findings indicate that although hypersensitivity reactions are common in general, occurring in almost 1 of every 6 patients treated intravenously with carboplatin, their clinical picture is variable, leading to discontinuation of treatment in only 6% of patients. This is not the case when the intraperitoneal route of carboplatin administration is used when indicated.

Abstract
BACKGROUND Treatment options for patients with recurrent nonsmall cell lung carcinoma (NSCLC) remain limited as a result of poor activity of older agents after platinum-based therapy. In the current Phase II study, the authors evaluated the combination of gemcitabine and docetaxel in patients with recurrent NSCLC. METHODS Patients with advanced NSCLC (Stage IIIB-IV), a World Health Organization performance status (PS) < or = 2, prior paclitaxel plus platinum-based chemotherapy, and unimpaired hematopoietic and organ function were eligible. Chemotherapy was administered as follows: gemcitabine 1000 mg/m(2) was administered on Days 1 and 8 followed by docetaxel 100 mg/m(2) on Day 8, and this regimen was recycled every 21 days. Prophylactic granulocyte-colony stimulating factor was administered on Days 10-14 or until the patient achieved a white blood cell count > or = 5000/microL. RESULTS Of 43 patients who were entered on the study, 41 patients were evaluable for response, and all were evaluable for toxicity. The median patient age was 63 years (range, 47-70 years), the median PS was 1 (range, 0-2), there were 38 male patients, and there were 5 female patients. Four patients had Stage IIIA disease, 17 patients had Stage IIIB disease, and 22 patients had Stage IV disease. Histologies included 19 patients with adenocarcinoma, 18 patients with squamous cell carcinoma, and 3 patients with large cell carcinoma. Metastatic sites included lymph nodes in 28 patients, bone in 6 patients, liver in 5 patients, brain in 5 patients, lung nodules in 8 patients, adrenals in 7 patients, and other sites in 3 patients. All patients had received prior paclitaxel plus platinum-based treatment; 28 patients had received prior paclitaxel, ifosfamide, and cisplatin. Objective responses were partial response (PR) in 14 of 43 patients [33%; 95% confidence interval [95%CI], 18.5-46.6%], stable disease (SD) in 16 of 43 patients (37%; 95% CI, 22.8-51.6%), and progressive disease (PD) in 13 of 43 patients (30%; 95% CI, 16.3-43.7%). The median time to disease progression was 6 months (range, 1.0-20.0+ months), and the median survival was 8.5 months (range, 1.5-20.0+ months). The 1-year survival rate was 28%. Grade 3-4 neutropenia was experienced by 53% of patients (30% Grade 4), with 14% of patients experiencing febrile neutropenia. Grade 3 thrombocytopenia was experienced by 7% of patients (no Grade 4), whereas other Grade 3 nonhematologic toxicities were never encountered. CONCLUSIONS The combination of gemcitabine and docetaxel is active and is well tolerated in patients with advanced NSCLC who have failed prior taxane plus platinum chemotherapy. This regimen represents a tolerable and effective combination to apply in the palliative treatment of patients with recurrent NSCLC.

Abstract
We studied tropisetron (T) in patients with breast cancer receiving standard adjuvant chemotherapy with CEF (cyclophosphamide, epirubicin and 5-fluorouracil) over 3 consecutive cycles; T was administered alone or in combination with dexamethasone (D) or alprazolam (A). 50 women entered and during the 1st cycle patients received T i.v. before chemotherapy and the same dose orally on each of the following 3 days. In the 2nd cycle, T was administered together with D and during the 3rd cycle, T was combined with A and continued with T over the ensuing 3 days post-chemotherapy. Stress was present in 23 women and was evaluated for its impact on antiemetic response. Differences in the emetogenic response were found for nausea and vomiting mainly with the addition of A. The combination of T+A was superior to T and T+D in acute emesis (P<0.001). Concerning delayed emesis, differences were detected with both T+D and T+A (being equally effective) and superior to T alone (P<0.001). The emetogenic potential was decreased by the addition of A in comparison to T alone (P=0.001). Patients without stress had no difference, while patients with stress had a significantly better antiemetic result with the addition of D or A to T. In conclusion, T provides a satisfactory result in controlling nausea and emesis caused by moderately emetogenic CT regimens. Addition of D or A improves the antiemetic effect, and A provides better coverage in women with stress, a finding worth exploration in larger confirmatory studies.

Abstract
In this study, we analyzed the targeting of the somatic hypermutation (SHM) mechanism at specific hotspot sequence motifs in the V(H) and Vkappa genes of 10 follicular lymphoma (FL) cases and the Vkappa and Vlambda genes of 11 kappa- and six lamda-light chain expressing multiple myeloma (MM) cases. These sequences were analyzed for targeting of specific motifs, ie certain highly mutable trinucleotides (3-NTPs), the tetranucleotide (4-NTP) RGYW and its complementary, WRCY (where R = purine, Y = pyrimidine and W = A or T). Comparisons were carried out between mutation frequencies in RGYW vs WRCY and the incidence of mutations in complementarity determining region (CDR)-1 vs CDR2 vs CDR3. Statistically significant differences were obtained when comparing: (1) the ratio of mutations in 4-NTPs (RGYW, WRCY, RGYW+WRCY)/mutations in the whole V sequence in MM-Vkappa vs MM-Vlamda; (2) the total number of mutated 4-NTPs in MM-Vkappa vs FL-Vkappa; (3) the number of mutated RGYW 4-NTPs in MM-Vkappa vs FL-Vkappa and FL-V(H) vs FL-Vkappa; (4) the number of mutated WRCY 4-NTPs in MM-Vkappa vs FL-Vkappa (P= 0.006) and FL-V(H) vs FL-Vkappa; (5) the targeting of RGYW vs WRCY in the CDRs of FL-V(H) genes. Similar results (regarding statistical significance) were obtained when undertaking intergroup comparisons for 3-NTPs. These findings conform well with relevant data derived from normal peripheral B cells. The differences observed in favor of 4-NTP (RGYW and WRCY) targeting in FL-V(H) vs FL-Vkappa and MM-Vkappa vs FL-Vkappa may implicate differences in the evolution of SHM coupled with selection in different stages of B cell ontogeny. Several explanations can be offered for the fact that hotspot sequences were not always targeted by SHM in FL and MM: (1) other unrecognized motifs may be targets of SHM; (2) 'inappropriately' introduced mutations were fixed and propagated by the neoplastic process; (3) certain FL and MM cases might have lost their ability to correct mutations introduced in classic hotspots due to deficient mismatch-repair (MMR) mechanisms; conversely, in other cases with intact MMR function, the hotspot to non-hotspot targeting of somatic hypermutation is balanced.

Abstract
PURPOSE To evaluate the activity and tolerance of docetaxel in combination with mitoxantrone and granulocyte colony-stimulating factor (G-CSF) as front-line treatment in patients with metastatic breast cancer (MBC). PATIENTS AND METHODS Fifty-four previously untreated patients with MBC who had bidimensionally measurable disease were enrolled onto the study. Forty-eight (89%) patients had visceral metastases and nineteen (36%) had relapsed within twelve months following adjuvant chemotherapy. Docetaxel (100 mg/m2) was given on day 1 after appropriate premedication and mitoxantrone (20 mg/m2) on day 8. G-CSF (150 mcg/m2/d s.c.) was administered from day 2 to day 6 and from day 9 to day 15. The regimen was repeated every three weeks, on an outpatient basis. RESULTS In an intention-to-treat analysis, 9 (17%) CRs, 24 (44%) PRs, (overall response rate 61%; 95% confidence interval (CI): 48.1%-74.1%), 12 (22%) SD and 9 (17%) PD were observed. The median duration of response and the median time to tumor progression was 12.5 and 14 months, respectively. The overall median survival was 16.5 months, whilst the probability for one- and three-year survival was 61% and 35%, respectively. Grade 3-4 neutropenia occurred in 37 (69%) patients, and febrile neutropenia in 16 (30%); there was one death due to sepsis. Grade 3-4 thrombocytopenia occurred in four (8%) patients. Grade 2-3 neurosensory toxicity was observed in 8 (15%) patients and grade 2-3 asthenia in 24 (45%). CONCLUSIONS Docetaxel in combination with mitoxantrone and G-CSF support is an intensified and active front-line regimen for patients with MBC; despite its hematological toxicity, this regimen merits further comparison with other standard anthracycline- and/or taxane-based combinations.
