Abstract
20120 Background: Molecular profiling recently defined biological characteristics of several long-recognized breast cancer subtypes including ER-positive (luminal subtype), ER-negative/ERBB2-positive (ERBB2 subtype) and ER-negative/ErBB2-negative (basal-like subtype). Each of these particular subtypes has different impact on patient outcome and should be therefore taken in consideration for individual scoring calculations. Methods: The quantitative RNA expression levels of 70 relevant genes were simultaneously determined in fresh frozen samples of 317 primary breast cancer (BC) patients comprehending ER-positive (70%), ER-negative/ERBB2-positive (15%) and ERBB2-negative/ER-negative (15%) and with known follow-up data. Five years distant recurrence scoring systems were calculated by means of Cox-hazard regression models. Results: Two main prognostic scoring systems were developed: one based on genes relative to proliferation representing tumor growth and its velocity, the other based on proteases. A low proliferation score identified 30% of patients at very good prognosis (probability of distant recurrence 12%, CI: 1.5–22%) all belonging to the ER-positive subcategory as compared to cases with higher proliferation (probability of distant recurrence 31%, 32–38%). The probability to develop distant recurrence within 5 years for 30% of ERBB2-positive patients was of only 12% (CI 0–25%) when accompanied by low levels of proteases as compared to the remaining ERBB2-positive patients with a probability of recurrence of 40% (CI 22–54%). Conclusions: ER, ERBB2 and the expression levels of the few identified genes involved in tumor proliferation and invasion can be easily and precisely detected by means of QRT-PCR. This robust method allows fine tuned prognosis and gives predictive information for the treatment of individual breast cancer. [Table: see text]

Abstract
BACKGROUND Hormonal treatment for women with breast cancer is frequently proposed in the adjuvant as well as in the palliative setting. Therefore, many women are confronted with early menopause and prolonged oestrogen deprivation and consequently with a variety of quality of life issues, such as menopausal symptoms and fatigue. PATIENTS AND METHODS It was the aim of this study to explore the occurrence and frequency of menopausal symptoms in women with breast cancer, undergoing hormonal cancer treatment and to investigate their relationship with fatigue. A cross-sectional, quantitative approach was used in this multi-centre study. The Checklist for Patients with Endocrine Therapy (C-PET) and the International Breast Cancer Study Group (IBCSG) Linear Analogue Scales for patients with endocrine treatment were used. Descriptive statistics, as well as cluster analyses were performed. RESULTS Most frequent menopausal symptoms involved hot flashes/sweats, tiredness, weight gain, vaginal dryness and decreased sexual interest. There were significant differences between the fatigued and the non-fatigued population regarding the intensity of menopausal symptoms, emotional irritability and general coping. Cluster analyses supported a menopausal symptom cluster. CONCLUSIONS Fatigue accompanies menopausal symptoms and an association can be expected. Methods for routine screening for menopausal symptoms, including fatigue, are suggested as a relevant research issue in women with breast cancer undergoing hormonal treatment.

Abstract
High serum concentrations of insulin-like growth factor-1 (IGF-1) are associated with an increased risk of breast, prostate, colorectal, and lung cancer whereas IGF binding protein-3 (IGFBP-3) seems to exert a protective effect. Therefore, patients may benefit from low IGF-1 levels and high IGFBP-3 levels. This study evaluated whether adjuvant anthracycline-containing chemotherapy modulates IGF-1 and/or IGFBP-3 serum levels in breast cancer patients. In 18 patients undergoing adjuvant treatment for primary breast cancer, IGF-1 and IGFBP-3 serum levels were measured with immunoassays during chemotherapy regimens of either 5-fluorouracil, epirubicin and cyclophosphamide (FEC) or epirubicin and cyclophosphamide (EC). Mean pre-treatment values of IGF-1 and IGFBP-3 were 124+/-13 and 3698+/-186 ng/ml, respectively. No significant changes in IGF-1 and IGFBP-3 serum concentrations were observed during adjuvant anthracycline-containing chemotherapy. IGF-1 levels significantly correlated with IGFBP-3 levels before and during chemotherapy. In conclusion, these chemotherapy regimens do not seem to modulate IGF-1 or IGFBP-3 levels in a favourable or unfavourable way.

Abstract
We report on a randomised trial that aimed to compare the efficacy of continued daily prednisolone treatment during the entire induction phase, with prednisolone given for 2 weeks of each cycle in combination with VMCP (vincristine, melphalan, cyclophosphamide, prednisolone)-interferon-alpha 2b (IFN-alpha 2b) treatment in 299 previously untreated elderly patients (median age: 67 years) with multiple myeloma. After completion of induction treatment patients were randomised to IFN-alpha 2b with or without prednisolone, thrice weekly. Response rate was 62% in the continuous and 60% in the control arm (intent to treat analysis, P=0.81). Progression-free survival [median: 20 months vs. 19 months; hazard ratio (HR): 0.99, 95% confidence interval (CI): 0.74-1.33, P=0.97] and overall survival (median: 34 months vs. 37 months; HR: 1.16, 95% CI: 0.85-1.59, P=0.35) were similar in both groups. Reduced performance status (Eastern Cooperative Oncology Group, grades 2-4) was the predominant risk factor for poor survival followed by age >65 years, high beta2-microglobulin, and impaired renal function. There was more grades 3-4 dyspnoea and cardiac impairment and grades 1-2 hyperglycaemia, but less nausea, emesis and anaemia in patients on continuous prednisolone therapy. In conclusion, continuing prednisolone treatment during the entire duration of the induction phase with VMCP-IFN-alpha 2b did not improve outcome.

Abstract
Epidermal growth factor receptor (EGFR) expression has been associated with clinical outcome in some studies of renal-cell carcinoma (RCC). We investigated the efficacy and safety of gefitinib (IRESSA), an EGFR tyrosine kinase inhibitor, in RCC patients. This phase II trial recruited 28 patients with advanced, metastatic, or relapsed RCC. Patients received oral gefitinib 500 mg/day. Objective responses (ORs) were assessed every 2 months according to RECIST. Baseline tumor biopsies were analyzed immunohistochemically for EGFR expression. At trial closure (March 2003), no ORs were seen but 14 patients (53.8%) had stable disease. At extended analysis (August 2004), median time to progression was 110 days (95% confidence interval [CI]: 55, 117); median overall survival was 303 days (95% CI 180, 444). Gefitinib was generally well tolerated. Skin rash and diarrhea were the most common drug-related adverse events (AEs) [54 and 39% of patients, respectively] and the most common drug-related grade 3/4 AEs (both 11%). The majority of tumor biopsies (91%) had > or =70% of tumor cells expressing membrane EGFR. Despite the lack of ORs in this study, disease control was observed in 53.8% of patients. Gefitinib was generally well tolerated and no unexpected drug-related AEs were observed.

Abstract
BACKGROUND A phase I-II multicenter trial was conducted to define the maximal tolerated dose and describe the activity of an OCFL combination using oxaliplatin (OHP), irinotecan (CPT-11) and 5-fluorouracil (FU)/leucovorin (LV) in metastatic colorectal cancer (CRC). PATIENTS AND METHODS CRC patients not pretreated with palliative chemotherapy, with performance status < or =1 and adequate haematological, kidney and liver function, were eligible. Treatment consisted in weekly 24-h infusion 5-FU (2300 mg/m(2))/LV (30 mg) and alternating OHP (70-85 mg/m(2), days 1 and 15) and CPT-11 (80-140 mg/m(2), days 8 and 22) repeated every 5 weeks. OHP and CPT-11 were escalated in cohorts of three to six patients. RESULTS Thirty patients received a median of five cycles. Dose-limiting toxicity occurred at dose level 3, and the recommended dose was OHP 70 mg/m(2), CPT-11 100 mg/m(2), LV 30 mg and 5-FU 2300 mg/m(2)/24 h. Grade > or =3 toxicities were diarrhea 23%, neutropenia 20%, fatigue 7%, and neurologic 7%. Two febrile neutropenia episodes (one fatal) were recorded. Among 28 patients with measurable disease (90%), we observed two complete and 20 partial responses; overall RR was 78% (95% CI, 59% to 92%). Median time to progression and overall survival were 9.5 and 25.4 months, respectively. Seven patients underwent liver metastases resection. CONCLUSION OCFL is an overall well tolerated regimen with very high efficacy, which makes it most suitable for tumour control before surgery of metastatic disease.

Abstract
Although irinotecan 350 mg m−2 is a standard option for relapsed/refractory advanced colorectal cancer, there is some evidence that suggests that a higher dose may be more effective, with acceptable tolerability, following 5-fluorouracil (5-FU). This study assessed the optimal dosing strategy for irinotecan, along with treatment efficacy and safety. A total of 164 patients with metastatic colorectal cancer progressing after failure on 5-FU or raltitrexed received either 350 mg m−2 irinotecan (Group A; n=36) or 250, 350 or 500 mg m−2, according to individual patient tolerance (Group B; n=62) or based on risk factor optimisation (Group C; n=66). There were no complete responses. There was a trend towards a higher overall response rate in Group B (13%) than in Groups A (8%) and C (9%). Tumour control growth rate was high in all three groups: 58% in group A, 60% in Group B and 50% in Group C. A total of 34% of patients in Group B and 9% in Group C were able to receive a dose of 500 mg m−2. Median duration of response and time to progression were significantly longer in Groups A and B compared with Group C. No significant between-group differences for any adverse events were seen, although there was a small trend towards better tolerability in Group B. Individual dose escalation based on patient tolerance may allow more patients to receive a higher irinotecan dose without causing additional toxicity and can be an appropriate patient management strategy.

Abstract
BACKGROUND A phase I-II multicenter trial was conducted to define the maximum tolerated dose (MTD) according to tolerance and toxicity (primary objective), as well as to describe the clinical activity, in terms of response and survival (secondary objectives), of a combination of 5-fluorouracil (5-FU) in protracted continuous intravenous infusion (p.i.v.) with docetaxel and cisplatin for patients with advanced gastric cancer. PATIENTS AND METHODS Patients with measurable unresectable and/or metastatic gastric carcinoma, World Health Organization performance status < or =1, normal hematological and renal functions, adequate hepatic function and not pretreated for advanced disease by chemotherapy, received up to eight cycles of a combination of docetaxel on day 1, cisplatin on day 1 and 5-FU p.i.v. on days 1-14 (TCF) every 3 weeks, which was escalated up to the MTD, defined by the occurrence of dose-limiting toxicity in two patients in one dose level. RESULTS Fifty-two patients were accrued and treated (43 in the phase I part of the trial and nine additional at the recommended dose level). A median of five cycles/patient was given. The recommended dose of TCF was docetaxel 85 mg/m(2) on day 1, cisplatin 75 mg/m(2) on day 1 and 5-FU p.i.v. 300 mg/m(2)/day on days 1-14. Grade > or =3 toxicities were neutropenia 79%, alopecia 46%, fatigue 23%, mucositis 10%, diarrhea 19%, nausea/vomiting 13%, neurological 4% and palmar-plantar 2%. Ten non-fatal febrile neutropenia episodes were recorded in eight patients. There were no treatment-related deaths. Among 41 patients with measurable disease (79%), we observed one complete and 20 partial responses for an overall intent-to-treat response rate of 51% (95% confidence interval 35-67%). Five patients (20%) had stable disease for > or =12 weeks (four cycles). The median overall survival was 9.3 months. CONCLUSIONS 5-FU p.i.v. at 300 mg/m(2)/day for 2 weeks out of three could be safely added to the docetaxel-cisplatin (TC) combination, but the dose of docetaxel had to be reduced to 75 mg/m(2) in a subsequent phase II trial. This drug regimen seems to be very active in advanced gastric cancer. Comparison with both TC and ECF in a randomized SAKK trial is ongoing.

Abstract
GOALS OF WORK The aim of this study was to evaluate the occurrence of chemotherapy-induced nausea and vomiting (CINV) and its effect on patients' ability to carry out daily life activities following moderately to highly emetogenic, first-cycle chemotherapy in routine practice in cancer centers of four different European countries. PATIENTS AND METHODS This was a prospective, cross-sectional, nonrandomized, self-assessment study in 249 patients enrolled from cancer centers in Spain, Austria, Germany, and Switzerland. The study population consisted of 78% women, with a mean age of 54. Breast, lung, and ovarian cancers made up 75% of all cancers in the study. Patients received a mean of 2.0 chemotherapy agents and 2.5 antiemetic drugs. MAIN RESULTS A total of 450 emetic episodes experienced by 243 patients was recorded over 5 days following chemotherapy, with an average of 1.8 episodes per patient (range: 0-28). A higher percentage of patients (38%) suffered from delayed compared to acute emesis (13%). Between 42% and 52% of all patients suffered from nausea (visual analogue scale > or = 5 mm) on any one day, peaking at day 3. Using the Functional Living Index for Emesis (FLIE) questionnaire, 75% of patients with nausea and 50% with vomiting reported a negative impact of these conditions on performance of daily living. CONCLUSIONS CINV remains a significant problem in routine practice, particularly in the delayed phase posttreatment. Overall, CINV had a negative impact on patients' daily life.

Abstract
The objective of the trial is to evaluate the efficacy of capecitabine in patients with metastatic hormone-resistant prostate carcinoma (HRPC), in terms of prostate-specific antigen (PSA) response and clinical benefit (decrease of pain or analgesic score) and its safety profile. In all, 25 patients with HRPC were enrolled on a phase II trial of capecitabine (Xeloda) at a dose of 1250 mg m(-2) orally twice daily on days 1-14 every 21 days. The inclusion criteria were PSA serum levels >3 x upper limit of normal, a WHO performance status 0-2, age <85 years and adequate bone marrow, liver and renal function. In patients with grade 2 or higher haematological toxicity on day 1 of the treatment cycle, therapy was first delayed, and then continued at a lower dose. Trial end points were PSA response and clinical benefit defined by quality of life (QL) data and analgesic consumption. The median age of patients was 70 years (range 54-85 years). A median of three cycles of capecitabine was administered (range 1-8). PSA response was observed in three patients (12%, 95% CI 3-31%), with times to tumour progression of 18, 21 and 35 weeks, respectively. In these patients, the response durations were 12, 17 and 32 weeks, respectively. Minor PSA regression was also seen in two further patients. The median time to tumour progression of all patients was 12 weeks (95% CI 9-15 weeks). Haematological toxicity was minor, with leukopenia grade 3 observed in one patient. There were three deaths during trial treatment, respectively, due to sepsis following mucositis and leukopenia, presumed sepsis with mucositis induced by chemotherapy and concomitant radiotherapy and cerebral dysfunction progressing to coma. Hand-foot syndrome grades 2 and 3 were observed in four patients each. Clinical benefit was observed in five patients (20%, CI 7-41%). Based on toxicity data, we recommend a lower starting dose of 1000 mg x m(-2) orally twice daily. While capecitabine has some activity in HRPC, as suggested by observed PSA responses, we conclude that it is not worthwhile to investigate capecitabine monotherapy in a phase III trial. Combinations of capecitabine with other agents, such as vinorelbine or docetaxel, may prove to be more effective.

Abstract
The insulin-like growth factor (IGF) system performs multiple functions in normal tissue. IGFs are involved in normal mammary gland development, but have also been implicated in the pathogenesis of breast cancer. Epidemiological studies found an association between elevated serum levels of IGF-I and an increased risk for breast cancer. IGF-I is the major mediator of growth hormone (GH) action. On the cellular level, IGF-I has a strong influence on cell proliferation and it is a potent inhibitor of apoptosis. Further, IGFs are also involved in angiogenesis. These characteristics are the basis for their involvement in maintenance and progression of cancer. The functions of IGF-I are mainly mediated through the type-I IGF-receptor (IGF-IR). The availability of free IGF-I for interaction with IGF-IR is modulated by IGF binding proteins (IGFBP 1-6). Based on interactions with other receptors, including estrogen and epidermal growth factor receptors, combined targeted therapies may improve breast cancer treatment.

Abstract
OBJECTIVE In hormone refractory prostatic carcinoma (HRPCa), the majority of patients have bone metastases only, which are by definition non-measurable. This makes objective evaluation of chemotherapeutic agents difficult. Prostate specific antigen (PSA) as a dynamic model was analyzed as potential auxiliary end point in HRPCa. METHODS In the framework of a master protocol, the Swiss Group for Clinical Cancer Research (SAKK) is evaluating cytotoxic drugs in HRPCa since 1991. These prospective phase II trials include uniform requirements with regard to response, toxicity and quality of life. From the entire pool of patients, 40 with bidimensionally measurable metastases (lymph nodes, visceral organs) could be identified. PSA doubling time was calculated in patients with a rising PSA during therapy. RESULTS Objective best response to any given chemotherapeutic agent was: partial remission (PR) in six patients (15%), stable disease (SD) in 13 (32%) and progressive disease (PD) in 21 (53%). PSA remained stable or decreased in four of six patients with PR (67%), seven of 13 with SD (54%) but only in four of 21 with PD (19%) (Cochran-Armitage test for trend; p=0.015). The median PSA doubling time for patients with a rising PSA was 238 days in PR and 224 days in SD, compared to 113 days in PD (Wilcoxon test; p=0.002). CONCLUSIONS PSA doubling time is a potential auxiliary end point in the evaluation of cytotoxic drugs in HRPCa. Thus, also patients with non-measurable (bone) metastases could be included in analysis of response.

Abstract
PURPOSE Preclinical studies indicate positive interactions between capecitabine, an oral fluorouracil precursor, and gemcitabine, the current standard treatment for advanced pancreatic carcinoma (APC). In this study, we investigated the addition of capecitabine to gemcitabine treatment for patients with APC. PATIENTS AND METHODS This multicenter study included patients naïve to chemotherapy who had histologically or cytologically confirmed, nonresectable or metastatic pancreatic carcinoma. Gemcitabine was given at a fixed dose of 1,000 mg/m(2) on days 1 and 8 of a 21-day cycle. Capecitabine was given in increasing doses orally bid for 14 days followed by a 1-week rest. The maximum-tolerated dose (MTD) was defined as one dose level below the dose causing dose-limiting toxicity (DLT) in >or= one third of a cohort of six patients. We included an additional 15 patients at the MTD. RESULTS Thirty-six patients were included. DLT occurred at a dose of 800 mg/m(2) bid of capecitabine and consisted of myelotoxicity and mucositis. Hand-foot syndrome was not observed, and other toxic effects were mild. Thus, in this regimen, the recommended dose of capecitabine is 650 mg/m(2) bid. In 27 patients with measurable disease, we observed one complete and four partial remissions. In addition, significant drops (> 50% from baseline value) of the tumor marker CA 19-9 occurred in 14 of 24 assessable patients. CONCLUSION The combination of capecitabine and gemcitabine is well tolerated, with apparent efficacy in patients with APC. Therefore, it is currently being compared with gemcitabine monotherapy in a phase III study.

Abstract
The purpose of this study was to evaluate the efficacy of vinorelbine treatment in terms of prostate-specific antigen (PSA) response and clinical benefit (decrease of pain or analgesic score for the subgroup of patients with pain), as well as its toxicity in patients with progressive metastatic androgen-independent prostatic carcinoma. 44 patients with prostatic carcinoma progressing after orchiectomy or during treatment with hormonal agents were treated with vinorelbine at a dose of 30 mg/m(2) intravenously (i.v.) on days 1 and 8 of a 21-day cycle. Inclusion criteria were metastatic progressive prostatic carcinoma with prostate-specific antigen (PSA) serum levels >/=3 x upper limit of normal, World Health Organization (WHO) performance status </=2, age <85 years and adequate bone marrow, liver and renal functions. Treatment was continued until progression or a maximum of 12 cycles. Treatment was delayed for a week if haematological toxicity grade >/=2 was observed on the day of scheduled vinorelbine administration. 9 patients received less than three cycles, 6 due to rapid tumour progression. Treatment at day 1 had to be delayed in 13.7% of 183 cycles. Treatment at day 8 had to be omitted in 19.7% of all cycles. Grade >/=3 granulocytopenia occurred in 18% of patients. 4 patients had severe constipation. In 7 patients (15.9%, Confidence Interval (CI) 6.6-30.1%), a PSA response (>/=50% reduction of PSA levels) was observed. Among 8 patients with measurable disease, 3 had partial remission and 1 no change. Median time to PSA progression in 43 assessable patients was 11.9 weeks (range 3-52 weeks). Median duration of PSA response was 14 weeks (9-30 weeks). Clinical benefit was seen in 7 of 31 cases (23%) with baseline pain, there was no association with PSA response. Vinorelbine is a fairly well tolerated drug with a moderate single agent activity in patients with androgen-refractory prostate cancer.

Abstract
PURPOSE To determine the efficacy and tolerability of combining oxaliplatin with capecitabine in the treatment of advanced nonpretreated and pretreated colorectal cancer. PATIENTS AND METHODS Forty-three nonpretreated patients and 26 patients who had experienced one fluoropyrimidine-containing regimen for advanced colorectal cancer were treated with oxaliplatin 130 mg/m(2) on day 1 and capecitabine 1,250 mg/m(2) bid on days 1 to 14 every 3 weeks. Patients with good performance status (World Health Organization grade 0 to 1) were accrued onto two nonrandomized parallel arms of a phase II study. RESULTS The objective response rate was 49% (95% confidence interval [CI], 33% to 65%) for nonpretreated and 15% (95% CI, 4% to 35%) for pretreated patients. The main toxicity of this combination was diarrhea, which occurred at grade 3 or 4 in 35% of the nonpretreated and 50% of the pretreated patients. Grade 3 or 4 sensory neuropathy, including laryngopharyngeal dysesthesia, occurred in 16% of patients on both cohorts. Capecitabine dose reductions were necessary in 26% of the nonpretreated and 45% of the pretreated patients in the second treatment cycle. The median overall survival was 17.1 months and 11.5 months, respectively. CONCLUSION Combining capecitabine and oxaliplatin yields promising activity in advanced colorectal cancer. The main toxicity is diarrhea, which is manageable with appropriate dose reductions. On the basis of our toxicity experience, we recommend use of capecitabine in combination with oxaliplatin 130 mg/m(2) at an initial dose of 1,250 mg/m(2) bid in nonpretreated patients and at a dose of 1,000 mg/m(2) bid in pretreated patients.

Abstract
BACKGROUND Chemotherapy with paclitaxel and carboplatin 3-weekly is active in many tumors. Major toxicities are myelosuppression and neurotoxicity. Weekly administration of taxanes allows high dose intensity with reduced toxicity. PATIENTS AND METHODS 131 patients with solid tumors were treated as outpatients with paclitaxel 75 mg/m(2) and carboplatin AUC 2-3 days 1, 8, 15 every 4 weeks irrespective of pretreatment and partly in neoadjuvant and multimodal concepts. RESULTS 125 patients (median age 58 years) were evaluable for response and toxicity, of whom 45 suffered esophageal carcinoma (19 patients in neoadjuvant treatment) and 31 non-small cell lung cancer. 49 patients were pretreated. 23 patients received concomitant radiotherapy of esophagus or lung in doses ranging from 40 to 60 Gy. We observed a low hematologic toxicity with 15.2% grade-III/IV leukopenia/granulocytopenia and 3.2% thrombocytopenia grade III/IV. Neurotoxicity grade II was reported in 14 patients. Main toxicity with radiotherapy was esophagitis grade II or III in 7 out of 23 patients. Overall response rate was 54.2%. 5 out of 19 patients treated neoadjuvantly for esophageal cancer reached a pathological complete response. CONCLUSIONS Weekly paclitaxel and carboplatin is safe and feasible in outpatients and a high dose intensity can be achieved. The favorable toxicity profile allows treatment of elderly and pretreated patients. Response rate is high including pathological complete responses and responses appear quickly, making this therapy most suitable for multimodal and neoadjuvant treatments.

Abstract
BACKGROUND Systemic IL-2 has shown some activity in metastatic melanoma, but its use is severely limited by toxicity. TG2001 is a product in which the human IL-2 cDNA was incorporated into the genome of Vero cells, a monkey fibroblast cell line. The goal of this intratumorally applied therapy was to create an antitumor immune response stimulated by xeno-antigens and local production of IL-2 in the close vicinity of tumor-specific antigens. TG2001 was reported to have a good safety profile in two previous dose-escalating phase I studies performed in 18 patients with various solid tumors, with encouraging clinical responses in three patients. The objectives of this study were to evaluate the tolerance and incidence of tumor regression in patients with metastatic melanoma, following repeated administration of Vero-IL-2 cells. PATIENTS AND METHODS This was on open-label, randomized phase II study comparing two doses of Vero-IL-2, 5x10(5) and 5x10(6) cells. Twenty-eight patients with metastatic melanoma were enrolled in the study, 14 in each treatment group. Patients received TG2001 by intratumoral injection on days 1, 3, and 5 every 4 weeks for four cycles, and every 8 weeks thereafter, until evidence of progressive disease (PD). Criteria for patient selection included histologically proven metastatic melanoma, with one tumor accessible for product administration, and at least another tumor site for response assessment. Evaluation included tumor measurements, humoral and T cell-mediated local and systemic immune response, humoral response to Vero cells, adverse events and standard laboratory parameters. RESULTS None of the patients achieved a confirmed objective response. Stable disease (SD) was seen in six (43%) and eight patients (57%) at the 5x10(5) and the 5x10(6) dose level, respectively. Two patients, one in each group, died during the study (i.e., within 1 month after the last injection) due to PD. Three patients exhibited antibody responses to Vero cells. T-cell immunity, serum cytokine levels and cytokine mRNA expression in tumor biopsies did not show meaningful alterations after therapy, except for a trend toward an increase in intratumoral TH2 cytokine (IL-4 and/or IL-10) levels. The study drug was well tolerated at both dose levels and side effects mainly consisted of injection site pain and erythema, and pyrexia. CONCLUSION The intratumoral administration of TG2001 was generally well tolerated in patients with metastatic melanoma, and transient disease stabilization was observed in 50% of patients.

Abstract
Two multicentre phase II trials were designed to determine if tumour responses can be achieved in progressive small-cell lung cancer (SCLC) or non-small cell lung cancer (NSCLC) patients treated with ISIS 5132, an inhibitor of C-raf kinase mRNA expression (CGP 69846A; ISIS Pharmaceuticals Inc, Carlsbad, CA), and to further characterise the safety of the compound. Between August 1998 and November 1999, 26 patients (18 NSCLC, 8 SCLC) were entered. Out of these, 23 were eligible, 22 (18 NSCLC, 4 SCLC) were treated with ISIS 5132 (2 mg/kg/day, 21 days continuous intravenous (i.v.) infusion every 4 weeks) and were evaluable for toxicity and 18 (15 NSCLC, 3 SCLC) were evaluable for efficacy. For the whole group haematological toxicity did not exceed grade 2. One patient experienced a grade 4 increased prothrombin time. Non-haematological toxicity was mild to moderate, with the observation of asthenia and nausea and vomiting. Progressive disease (PD) was diagnosed in 10 patients (8 NSCLC and 2 SCLC). 8 more patients (7 NSCLC, 1 SCLC) were considered as treatment failures. In conclusion, this study using ISIS 5132 with this dose and schedule of administration excludes a 20% response rate with 95% confidence intervals for NSCLC and cannot draw any conclusions for SCLC patients as only a few were involved in the study.

Abstract
Surgical treatment of locally advanced gastric carcinoma still results in unsatisfactory survival results. The addition of adjuvant chemotherapy has been shown to be of little value and is not considered standard practice. Preoperative chemotherapy, however, has a strong theoretical basis and may achieve significant tumor shrinkage and downstaging and thus allow complete resection of cancers previously judged by the responsible surgeon to be inoperable. However, it has not yet been demonstrated whether preoperative chemotherapy prolongs the survival of patients with potentially resectable cancers. Based on theoretical reasons, preoperative chemotherapy may be expected to be more efficient than postoperative chemotherapy. Various phase II trials have shown the feasibility of this approach, and encouraging results were found. Differing diagnostic methods, inclusion criteria, and chemotherapy regimens hamper direct comparisons between the trials. Several useful new drugs including taxanes and camptothecins and promising chemotherapy regimens incorporating continuously infused 5-fluorouracil have been introduced recently. Ongoing large randomized clinical trials (MAGIC trial, EORTC, SAKK) currently study the efficacy of preoperative chemotherapy in locally advanced gastric carcinoma.

Abstract
PURPOSE In a phase II trial, the activity of carzelesin, a cyclopropylpyrroloindole prodrug analog, was assessed. PATIENTS AND METHODS Carzelesin was used as second- or third-line chemotherapy in patients with breast, ovarian, head and neck cancer and non-Hodgkin's lymphoma, and as first-line chemotherapy in patients with colorectal and gastric cancer and melanoma. The drug was given as a bolus infusion at a 4-weekly dose of 150 microg/m2. A total of 140 patients were entered and a total of 285 courses were administered. RESULTS In general, the compound was well tolerated. Myelotoxicity was the most common toxicity. Grade 3 and 4 leukopenia was observed in 18.6% of the courses, neutropenia in 20.3%, thrombocytopenia in 16.2% and anemia in 8.7%. Double nadirs were seen in a total of 41 courses for neutrophils, in 40 for leukocytes and in 3 for platelets. Non-hematological toxicity was very mild. Only one partial response in a patient with melanoma was seen. CONCLUSIONS At this dose and schedule carzelesin did not yield activity in the types of tumors studied.
