Abstract
Aims and Background In a prior study with a new non-cisplatin-based regimen including mytomycin C, etoposide and vindesine (MEV I) we observed a 37% response rate and very low toxicity in stage IV non small cell lung cancer. In an attempt to improve the activity of MEV I we evaluated a new regimen, MEV II, a modification of MEV I in which vinorelbine replaced vindesine. Methods 21 Patients with metastatic stage IV non small cell lung cancer entered the phase II trial and were treated with the MEV II regimen (mitomycin C 8 mg/m2, i.v., d 1, etoposide 100 mg/m2, i.v., d 1-3, vinorelbine 30 mg/m2, i.v., d 1, every 4 weeks. Results We observed a partial response rate of 30% (95% confidence limits 10-50) with a median survival of 6 months. The worst reported toxicity was leukopenia grade 4 in 10% of patients including one who died of sepsis and grade 3 in 20%. Conclusions The MEV II regimen showed a similar activity but greater toxicity than MEV I.

Abstract
Aims In February 1986 we began a study to test the activity of mitomycin C (12 mg/m2) plus vinblastine (6 mg/m2) on day 1 of a 28-day cycle (MV) as second or third-line chemotherapy for metastatic breast cancer patients. Methods As of February 1988 the study was stopped after 26 patients had been enrolled. The median age of the patients was 54 years (range 35-78); all patients were progressive from chemotherapy; 15 (57.7 %) patients were treated as second and 11 (42.3 %) as third line; 19 (73.1 %) patients had received anthracyclines as first (13 patients) or second-line (6 patients) chemotherapy; 18 (69.2 %) patients had visceral Involvement; 7 (26.9 %) had one metastatic site, 11 (42.3 %) two sites, 6 (23.1 %) three sites and 2 (7.7 %) four sites. Results Overall, 86 cycles were administered, with a median number of 3 cycles per patient. Toxicity was mild; hematologic side effects required discontinuation of treatment in 3 cases. Vomiting occurred in 3 (11.5 %) patients, nausea in 5 (19.2 %). Moderate neurologic toxicity was recorded in 6 (23 %) patients. No complete and 3 partial responses were observed. The objective response rate was 11.5 % (exact 95 % confidence interval, 2.4-30.1). Responses occurred independently of disease-free interval, dominant metastatic site, response to previous chemotherapy, previous anthracycline and line of treatment; all responses were recorded in patients under 50 years of age. Kaplan-Meier estimated median time to progression and overall survival were 13 and 40 weeks, respectively. Conclusion The MV regimen was well tolerated but showed little activity in pretreated metastatic breast cancer.

Abstract
Twelve patients with malignant pleural mesothelioma were subjected to mitomycin C (MMC) and vindesine (VDS) chemotherapy (MMC 10 mg/m2, i.v., d 1; VDS, 3 mg/m2, i.v., d 1–8, every 4 weeks). No objective response was obtained; 3 (25%) patients had stable disease and 9 (75%) progression of disease. We conclude that MMC plus VDS is an ineffective combination chemotherapy in the treatment of malignant pleural mesothelioma.

Abstract
Twenty patients with stage IIIA-IIIB non-small-cell lung cancer were treated with cisplatin, epirubicin and VP-16 (PEV) neoadjuvant chemotherapy (CDDP, 70 mg/m2, i.v., d 1; EDX, 60 mg/m2, i.v., d 1; VP-16, 100 mg/m2, i.v., d 1-2-3; every 3 weeks). A partial response was obtained In 11 cases (55%), stable disease in 3 cases (15%), and progressive disease in 6 cases (30%). After chemotherapy, 8 (40%) patients, all achieving a partial response, were elegible for surgery: 5 (25%) had a complete resection (4 IIIA and 1 IIIB) and 3 (15%) an incomplete resection. The treatment was well tolerated. These data show that PEV is an active regimen for neoadjuvant chemotherapy in NSCLC and recommend this therapeutic approach for stage IIIA patients.

Abstract
Sixty-nine patients, 32 with limited and 37 with extensive small cell lung cancer (SCLC), were admitted to the present study. Patients with limited disease underwent alternating combination chemotherapy consisting of CAV (cyclophosphamide, adriamycin, vincristine) and PE (cisplatin and etoposide) regimens and concurrent high dose thoracic radiotherapy (6,000 cGy); prophylactic brain irradiation (3,000 cGy) was administered to complete responders. Patients with extensive disease received the same alternating chemotherapy but not radiotherapy. In the 25 evaluable patients with limited disease we obtained an objective response (OR) in 80% with a complete response (CR) in 54% and partial response (PR) in 24%, stable disease (SD) in 4% and progressive disease (PD) in 16%. Median duration of response was 9.5 months for CR and 8.5 months for PR. Median survival was 14 months for all patients with 12% long-term survivors. Toxicity was acceptable. In the 32 evaluable patients with extensive disease we observed 65.6% OR with 18.7% CR and 46.8% PR, 9.3% minimal response and 25% PD. Median duration of response was 7 months for CR and 8 months for PR. Median survival was 10 months for all patients. The treatment was well tolerated. Our study did not show a therapeutic advantage for alternating combination chemotherapy in SCLC and failed to show the use of high dose chest radiotherapy in combined modality for limited disease.

Abstract
We report our experience in the treatment of pleural effusion in 25 patients with metastatic breast cancer. Seventeen patients received initial systemic therapy and in 13 of them local intrapleural therapy was subsequently employed; the remaining 8 patients received local therapy only. Several modalities of local treatment were used: intrapleural chemotherapy with thiotepa and 5-fluorouracil; the production of pleural adhesion by the use of chest drainage alone or associated with instillation of sclerosing agents, such as nitrogen mustard or tetracycline. Of the 21 patients who were subjected to local therapy, 19 (90.5%) achieved an objective response (16 complete (76.2%) and 3 (14.34%) partial). Complete responses were observed exclusively in patients who had pleurodesis. Our data suggest that pleurodesis is the treatment of choice for neoplastic pleural effusion and that the use of tetracycline as a sclerosing agent is the most useful because of its availability, low cost and low morbidity.

Abstract
CEA, TPA, CA 15-3 were assayed in 238 patients in follow-up for breast cancer after surgery. CA 15-3 showed the best sensitivity and specificity; the predictive value of a positive CA 15-3 test was three times higher than CEA and TPA. No association was found between marker positivity and the number of organs involved by metastases. CA 15-3 positivity was significantly associated with visceral rather than soft tissue recurrences; no significant similar association was observed for CEA and TPA. CA 15-3 serum levels were early predictors of relapse in four out of nine patients within a 6-12 month follow-up period.

Abstract
CA 15-3, TPA and CEA were assayed before surgery in 60 patients with breast cancer. A significant association was found between preoperative CA 15-3 levels and some of the most important prognostic factors in breast cancer, such as lymph node status and tumor size. No similar association was discovered for CEA and TPA. Preoperative CA 15-3 levels were also significantly associated with early recurrences of the disease, thus adding useful information to prognosis especially in N + patients.

Abstract
Postmenopausal women with localised, early breast cancer (n = 285) were enrolled in a prospective subprotocol of the 'arimidex, tamoxifen, alone or in combination' (ATAC) trial to assess gynaecological abnormalities arising during treatment with anastrozole (1 mg/day) or tamoxifen (20 mg/day). After 6 years' follow-up, there appeared to be non-significantly fewer endometrial abnormalities with anastrozole than with tamoxifen (12.4% vs 20.2%, odds ratio 0.52; 95% confidence intervals 0.20, 1.32; p = 0.17). The time to first endometrial abnormality was non-significantly longer for patients receiving anastrozole compared with tamoxifen (hazard ratio 0.57; 95% confidence intervals 0.26, 1.22; p = 0.15), with most abnormalities occurring within the first year of treatment. Fewer patients treated with anastrozole appeared to require medical intervention for endometrial abnormalities, compared with patients on tamoxifen. This study showed that there was no significant difference in endometrial pathology between anastrozole and tamoxifen treatment groups.

Abstract
We have evaluated the activity and safety of gefitinib, a small-molecule epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor, in combination with docetaxel as first-line treatment of women with metastatic breast cancer (MBC). In total, 41 patients with MBC were enrolled in a first-line combination therapy study with oral gefitinib (250 mg day−1) and intravenous docetaxel (75 mg m−2, the first 14 patients; or 100 mg m−2, the following 27 patients, on day 1 of a 3-week cycle). Out of 41 patients, 38 received at least one cycle of therapy. There were no differences in activity or tolerability between the two docetaxel doses. G3/4 toxicities were neutropenia (49%), diarrhoea (10%), acne-like rash (5%), and anaemia (2%). Complete plus partial responses (CR+PR) were observed in 22 out of 41 patients with a 54% response rate (95% confidence interval (CI) 45–75%). The 22 patients that achieved a response following six cycles of docetaxel plus gefitinib continued gefitinib monotherapy (median duration, 24 weeks; range, 2–108+ weeks). Two patients with PR following combination therapy achieved a CR during gefitinib monotherapy. Complete plus partial responses correlated with oestrogen receptor (ER) status, since they occurred in 19 out of 27 (70%) patients with ER-positive tumours as compared to three out of 14 (21%) patients with ER-negative tumours (P=0.01).

Abstract
LBA520 Background: Docetaxel is among the most active drugs for advanced breast cancer and it has recently shown efficacy in the adjuvant setting too. This trial is aimed at comparing the efficacy and tolerability of a sequential approach of a chemotherapy combination regimen containing docetaxel to a standard anthracycline-based regimen as adjuvant therapy in node-positive (N+) early breast cancer. Methods: Between July 1998 and July 2002, 972 N+ early breast cancer patients were randomized to either arm A (E→CMF): Epirubicin (E) 120 mg/m2 iv d1 q21 × 4 cycles followed by Cyclophosphamide 600 mg/m2 iv, Methotrexate 40 mg/m2 iv and Fluorouracil 600 mg/m2 iv (CMF) d1,8 q28 × 4 cycles; or armB (E→T→CMF) in which Docetaxel 100 mg/m2 iv (T) d1 q21 × 4 cycles was administered after the 4th cycle of E and before the 1st cycle of CMF. Treatment allocation was performed by a computer program using a dynamic balancing algorithm. Balancing factors were: center, lymph node involvement (1 to 3, 4 to 9, >10), estrogen receptor status (negative/positive/unknown), menopausal status (pre/post). During chemotherapy pts were subjected to physical examination and blood chemistry tests every 3 wks, hematology was repeated weekly. At the completion of treatment pts were followed up every 3 months for the first 2 years, every 6 months for years 3–5 and every 12 months for years 6–10. Primary endpoint was disease free survival (DFS) and secondary endpoints were tolerability and overall survival (OS). The study was designed to detect a hazard ratio of 0.70, assuming an α of 0.05 (two sided), a power of 0.80 and an expected DFS in Arm A of 0.65 at 5 years. This required 480 pts per Arm and 250 events. Results: As of March 27th 2006, 486 pts were enrolled in arm A and 486 in arm B, 252 primary events were recorded and the median follow up was 53 months. DFS at 5 years was 0.67 in arm A vs 0.74 in arm B with an estimated Hazard Ratio (HR) of 0.80 (95% CI: 0.62–1.03, p = 0.079). After adjustement by predefined balancing factors (ER, Nodal and menopausal status) the HR was 0.78 (95% CIs: 0.61–1.00; p = 0.05). As for OS, 117 deaths were observed with HR of 0.74 (95% CIs: 0.51–1.07, p = 0.10). Conclusions: Sequential E→T→CMF yields a borderline significant improvement of DFS. Follow up update is still ongoing. [Table: see text]

Abstract
The aims of this multicentre, randomised phase III trial were to evaluate: (1) the role of levamisol (LEV); and (2) the role of folinic acid (FA), added to 5-fluorouracil (5FU) in the adjuvant treatment of colorectal cancer. Patients with histologically proven, radically resected stage II or III colon or rectal cancer were eligible. The study had a 2x2 factorial design with four treatment arms: (a) 5FU alone, (b) 5FU+LEV, (c) 5FU+FA, (d) 5FU+LEV+FA, and two planned comparisons, testing the role of LEV and of FA, respectively. From March 1991, to September 1998, 1327 patients were randomised. None of the two comparisons resulted in a significant disease-free (DFS) or overall (OAS) survival advantage. The hazard ratio (HR) of relapse was 0.89 (95% confidence intervals (CI): 0.73-1.09) for patients receiving FA and 0.99 (95% CI 0.80-1.21) for those receiving LEV; corresponding HRs of death were 1.02 (95% CI: 0.80-1.30) and 0.94 (95% CI 0.73-1.20). Nonhaematological toxicity (all grade vomiting, diarrhoea, mucositis, congiuntivitis, skin, fever and fatigue) was significantly worse with FA, while all other toxicities were similar. In the present trial, there was no evidence that the addition of FA or LEV significantly prolongs DFS and OAS of radically resected colorectal cancer patients.

Abstract
BACKGROUND Tamoxifen treatment results in a doubling of the risk of endometrial cancer after 1-2 years of treatment and a quadrupling after 5 years. Anastrozole, a third-generation aromatase inhibitor, with superior efficacy to tamoxifen, may also offer tolerability benefits in terms of effects on the endometrium. METHODS AND RESULTS A sub-protocol of the ATAC trial compared the incidence/type of intrauterine changes following treatment with these agents in a subgroup of patients (n = 285) from the main trial. After 2 years anastrozole treatment, endometrial thickness remained </= 5 mm (baseline: 3.0 mm); in patients receiving tamoxifen, endometrial thickness increased by 3.2 mm to 7.0 mm, with a similar trend in the combination group. At baseline, 26/285 patients (9.1%) had endometrial abnormalities, most commonly polyps. After 2 years the number of endometrial abnormalities appeared lower with anastrozole treatment compared with tamoxifen although these differences were not statistically significant (odds ratio: 0.44; 95% confidence interval 0.146, 1.314; P = 0.14). Most abnormalities occurred within the first year of treatment (anastrozole: 4/6; tamoxifen: 7/10; combination: 10/16; total: 21/32). Fewer patients in the anastrozole group (1.4%) required medical intervention (tamoxifen 12.5%; combination 13.6%). CONCLUSIONS Fewer endometrial abnormalities occurred during 2 years treatment with anastrozole compared with tamoxifen although statistical significance was not reached in this sub-protocol analysis.

Abstract
The aim of the study was to assess the toxicity and the clinical activity of biweekly oxaliplatin in combination with infusional 5-fluorouracil (5-FU) and folinic acid (FA) administered every 2 weeks (FOLFOX-4 regimen) in patients with advanced gastric cancer (AGC). A total of 61 previously untreated AGC patients were treated with oxaliplatin 85 mg m−2 on day 1, FA 200 mg m−2 as a 2 h infusion followed by bolus 5-FU 400 mg m−2 and a 22 h infusion of 5-FU 600 mg m−2, repeated for 2 consecutive days every 2 weeks. All patients were assessable for toxicity and response to treatment. Four (7%) complete responses and 19 partial responses were observed (overall response rate, 38%). Stable disease was observed in 22 (36%) patients, with progressive disease in the other six (10%) patients. Median time to progression (TTP) and median overall survival (OS) were 7.1 and 11.2 months, respectively. National Cancer Institute Common Toxicity Criteria grade 3 and 4 haematologic toxicities were neutropenia, anaemia and thrombocytopenia in 36, 10 and 5% of the patients, respectively. Grade 3 peripheral neuropathy was recorded in three (5%) patients. FOLFOX-4 is an active and well-tolerated chemotherapy. Response rate (RR), TTP and OS were comparable with those of other oxaliplatin-based regimens, suggesting a role for this combination in gastric cancer.

Abstract
The c-erbB family of receptors includes four distinct receptors, namely c-erb B1, 2, 3 and 4 (HER1, 2, 3 and 4, respectively). Trastuzumab (T) is a recombinant humanized anti-HER2 monoclonal antibody that binds the extracellular domain of the receptor and blocks intracellular signalling. In clinical studies of T, either alone or in combination with chemotherapy, in HER2 overexpressing metastatic breast cancer patients, a significant benefit was obtained--improved response rates and survival, when T was combined with chemotherapy. Several trials of adjuvant T, either singly or in combination with chemotherapy, are in progress in early breast cancer patients. Pertuzumab defines a new class of HER2 inhibitors, "dimerization inhibitors" that block both homo- and hetero-dimerization of HER2. In preclinical studies pertuzumab is inhibitory to breast, prostate and non small cell lung cancer cell lines, both over and non overexpressing HER2. In phase I clinical trials pertuzumab has shown activity in a number of human cancers. A phase II program is in progress.

Abstract
The sequential doxorubicin → CMF (CMF=cyclophosphamide, methotrexate, fluorouracil) regimen has never been compared to CMF in a randomised trial. The role of adding goserelin and tamoxifen after chemotherapy is unclear. In all, 466 premenopausal node-positive patients were randomised to: (a) CMF × 6 cycles (CMF); (b) doxorubicin × 4 cycles followed by CMF × 6 cycles (A → CMF); (c) CMF × 6 cycles followed by goserelin plus tamoxifen × 2 years (CMF → GT); and (d) doxorubicin × 4 cycles followed by CMF × 6 cycles followed by goserelin plus tamoxifen × 2 years (A → CMF → GT). The study used a 2 × 2 factorial experimental design to assess: (1) the effect of the chemotherapy regimens (CMF vs A → CMF or arms a+c vs b+d) and (2) the effect of adding GT after chemotherapy (arms a+b vs c+d). At a median follow-up of 72 months, A → CMF as compared to CMF significantly improved disease-free survival (DFS) with a multivariate hazard ratio (HR)=0.740 (95% confidence interval (CI): 0.556–0.986; P=0.040) and produced a nonsignificant improvement of overall survival (OS) (HR=0.764; 95% CI: 0.489–1.193). The addition of GT after chemotherapy significantly improved DFS (HR=0.74; 95% CI: 0.555–0.987; P=0.040), with a nonsignificant improvement of OS (HR=0.84; 95% CI: 0.54–1.32). A → CMF is superior to CMF. Adding GT after chemotherapy is beneficial for premenopausal node-positive patients.

Abstract
OBJECTIVES To determine whether COX-2, bcl-2 and neoangiogenesis are related to human prostate cancer relapse after definitive surgical treatment and progression toward androgen independence and to evaluate the association between the patterns of these tumoral biomarkers and other standard clinico-pathological parameters (such as Gleason score, PSA, TNM stage). MATERIALS AND METHODS We retrospectively analyzed the records on 126 prostate cancer samples from patients treated at our University Hospital from 1995 to 2002. The 72 patients with clinically localized disease (group 1) had undergone radical prostatectomy. Another 54 patients (group 2) had metastatic androgen-independent disease. Archived material relating to the subjects was then immunostained for bcl-2, COX-2 and CD-31, using an anti-bcl-2 monoclonal primary antibody, an anti-COX-2 polyclonal rabbit antibody and an anti-CD-31 monoclonal mouse antibody to evaluate neoangiogenesis (MVD, microvessel density). RESULTS We found that bcl-2, COX-2 and MVD expression increased from group 1 to group 2. The intergroup difference was significant only for high MVD (P < 0.05). On the other hand, high MVD, high bcl-2 and high COX-2 expression was correlated with a higher PSA level (P < 0.01), whereas only a high MVD was also related with Gleason score (P < 0.05). We used univariate analysis to evaluate the prognostic impact of biologic and clinico-pathologic parameters on the disease-free-survival of 72 patients treated by radical prostatectomy. A total of 30 patients (41.6%) experienced biochemical relapse; bcl-2, COX-2 and MVD significantly correlated with disease relapse in these patients. In fact, we observed disease relapse in 24/45 (53%) with high bcl-2 expression, in 15/21 (71%) with a high MVD count and finally, in 30/58 (52%) with high COX-2 expression. Finally, PSA value and Gleason score were the only two biologic markers significantly associated to disease relapse in a multivariate analysis. CONCLUSIONS Our results strongly support a role for bcl-2, COX-2 and angiogenesis in the development and progression of prostate cancer. Of course, we are aware of the small sample size considered in our study. Further investigations would better clarify the prognostic and therapeutic implications of these findings.

Abstract
BACKGROUND The 'Arimidex', Tamoxifen, Alone or in Combination (ATAC) trial is a randomized, double-blind trial comparing anastrozole ('Arimidex'), alone or in combination with tamoxifen, relative to tamoxifen alone as 5 year adjuvant treatment for post-menopausal women with early breast cancer. Since tamoxifen is associated with endometrial pathology, the ATAC endometrial sub-protocol was initiated to establish the background prevalence of intrauterine pathology, and to assess prospectively the incidence and nature of intrauterine changes following endocrine therapy. Another aim was to provide data from which advice could be generated on the best endometrium screening method for patients receiving tamoxifen. METHODS Patients underwent endometrial assessments at entry to the sub-protocol. The baseline investigations comprised transvaginal ultrasound scanning (TVUS), a hysteroscopy and an endometrial biopsy. RESULTS A total of 285 gynaecologically asymptomatic women from 31 centres in 10 countries entered the endometrial sub-protocol. The mean uterine volume was 47.7 cm3. The median endometrial thickness overall was 3 mm. Twenty-four histologically confirmed, pathological changes were observed. Twenty-three pathologies were confirmed by TVUS, and 21 were identified by hysteroscopy and confirmed by histopathology. Women with or without intrauterine pathology had median endometrial thickness of 5 and 3 mm respectively. CONCLUSIONS The presence of pathology was associated with increased endometrial thickness. The relative sensitivity and specificity of hysteroscopy and endometrial thickness for the diagnosis of endometrial pathology was comparable to other studies. If screening of the endometrium prior to treatment is appropriate, this study supports the use of an endometrial thickness of 3 mm, as assessed by TVUS, as a threshold for needing further investigation. This study demonstrates that if the endometrial thickness is >3 mm, hysteroscopy and biopsy is the optimal method of detecting intrauterine pathology in women with breast cancer who are about to commence endocrine treatment.

Abstract
OBJECTIVE The ATAC (Arimidex, Tamoxifen, Alone or in Combination) trial is a randomised, double-blind trial comparing 'Arimidex' (anastrozole), alone or in combination with tamoxifen, relative to tamoxifen alone as a five year adjuvant treatment for postmenopausal women with early breast cancer. Because tamoxifen is associated with endometrial pathology, the ATAC endometrial subprotocol was initiated to establish the background prevalence of pathology, and to assess prospectively the incidence and nature of intrauterine changes before and following endocrine therapy. SETTING International. POPULATION AND STUDY DESIGN: Two hundred and eighty-five women entered the subprotocol: the mean age was 60 years (range 44-80 years); 113 women (40%) had taken hormone replacement therapy prior to randomisation, and 238 women were parous (84%). The age at onset of the menopause was 32-58 years, with the majority becoming menopausal between 46 and 55 years of age. Two hundred and seventy-two women had a hysteroscopy before they commenced trial medication. Hysteroscopy was performed successfully in 265 women. In six women, failure of hysteroscopy at baseline led to withdrawal from the study. Three of the women who withdrew had a pipelle biopsy taken. Therefore, the total number of endometrial biopsies at baseline was 268. MAIN OUTCOME MEASURES To assess the demographic characteristics of women entering the endometrial subprotocol and their hysteroscopic and histological findings before commencing trial medication. RESULTS At hysteroscopy, there was a diagnosis of endometrial polyps in 34 women (13%), fibroids in 16 women (6%) and one case of suspicious endometrium, which was confirmed as a polyp on histology. Only 21 of the 34 polyps seen hysteroscopically were proven histologically (62% accuracy of hysteroscopy). Final histology found the prevalence of endometrial diagnostic categories as follows: 123 inactive endometrium (46%), 20 benign polyps (7%), 17 secretory endometrium (6%), 7 proliferative endometrium (3%), 3 atypical hyperplasia (2 in a polyp), 1 simple hyperplasia (in a polyp) and 1 fibroid. The remaining women had pipelle samples with insufficient tissue obtained, indicating a normal endometrial cavity. CONCLUSION This is the first study of such size in gynaecologically asymptomatic breast cancer patients. This paper describes the findings in individual patients before any trial treatment was given. In this baseline group, 82% (219/268) of women had a normal endometrial cavity; 18% (49/268) had endometrial activity (proliferative or secretory endometrium in 9%) or an intracavity abnormality (hyperplasia, polyps and a fibroid in 9%). In total, 36% of biopsies had insufficient tissue for diagnosis, which in combination with a normal hysteroscopy was classed as normal. The appearance of a polyp hysteroscopically in this group was not proven histologically in approximately 40% of cases. The development of uterine pathology over time in the ATAC study will subsequently be assessed against the findings of this baseline paper.

Abstract
In the present paper, we investigated the relationship between the growth inhibitory effects of recombinant interferon-alpha2b (rIFN-alpha2b) and poly (ADPR) polymerase-1 (PARP-1) activity in the human squamous KB cancer cell line. Growth inhibition of the KB cells mediated by 1000 IU/ml of rIFN-alpha2b was accompanied by a transient rise in PARP-1 specific activity 24 h after rIFN-alpha2b treatment, confirmed by both the increase of intracellular poly (ADP-ribose) content and the PARP-1 auto-modification level. At longer times of incubation, the onset of apoptosis accompanied KB cell growth inhibition, as demonstrated by both flow cytometry and western-blotting analysis showing an 89 kDa apoptotic fragment of PARP-1. Moreover, pretreatment of the cells with the PARP-1 inhibitor, 3-aminobenzamide (3-ABA), at non-cytotoxic concentrations (1 mM), reduced the cell-growth inhibition, cell-cycle perturbation and apoptosis caused by rIFN-alpha2b. Taken together, these results strongly suggest that PARP-1 may be directly involved in the effects of rIFN-alpha2b in the KB cancer cell line.

Abstract
The mechanisms of tumor cell resistance to interferon-alpha (IFNalpha) are at present mostly unsolved. We have previously demonstrated that IFNalpha induces apoptosis on epidermoid cancer cells and EGF antagonizes this effect. We have also found that IFNalpha-induced apoptosis depends upon activation of the NH(2)-terminal Jun kinase-1 (Jnk-1) and p(38) mitogen-activated protein kinase, and that these effects are also antagonized by EGF. At the same time, IFNalpha increases the expression and function of the epidermal growth factor receptor (EGF-R). Here we report that the apoptosis induced by IFNalpha occurs together with activation of caspases 3, 6 and 8 and that EGF also antagonizes this effect. On the basis of these results, we have hypothesized that the increased EGF-R expression and function could represent an inducible survival response that might protect tumor cells from apoptosis caused by IFNalpha via extracellular signal regulated kinase 1 and 2 (Erk-1/2) cascades. We have found an increased activity of Ras and Raf-1 in IFNalpha-treated cells. Moreover, IFNalpha induces a 50% increase of the phosphorylated isoforms and enzymatic activity of Erk-1/2. We have also demonstrated that the inhibition of Ras activity induced by the transfection of the dominant negative Ras plasmid RASN17 and the inhibition of Mek-1 with PD098059 strongly potentiates the apoptosis induced by IFNalpha. Moreover, the selective inhibition of this pathway abrogates the counteracting effect of EGF on the IFNalpha-induced apoptosis. All these findings suggest that epidermoid tumor cells counteract the IFNalpha-induced apoptosis through a survival pathway that involves the hyperactivation of the EGF-dependent Ras->Erk signalling. The selective targeting of this pathway appears to be a promising approach in order to enhance the antitumor activity of IFNalpha.

Abstract
BACKGROUND AND AIM In vitro, methotrexate (MTX) is the best modulator for bolus 5-fluorouracil (5FU), whereas folinic acid (FA) is the best for continuous infusion. We evaluated the effect of 5FU modulated by both MTX (bolus administration) and FA (continuous infusion) as second-line treatment of patients with metastatic colorectal cancer. PATIENTS AND METHODS Entry criteria were: at least one 5FU-based chemotherapy regimen as first-line treatment for metastatic disease, or progression within twelve months after 5FU-containing adjuvant therapy. Treatment schedule: MTX 200 mg/m2 i.v. days 1 and 15; 5FU 600 mg/m2 i.v. bolus, days 2 and 16; 5FU 200 mg/m2 i.v. continuous infusion for 21 days, starting on day 29; FA 20 mg/m2 i.v. bolus weekly during the three weeks of 5FU infusion. Cycles were repeated every 56 days. The primary end-point was tumour control rate, including partial responses and stabilizations. RESULTS 34/35 patients enrolled were evaluable for response. Five (14.7%) had a partial response, 13 (38.2%) disease stabilization, and 16 (47.1%) progressed; tumour control rate was 52.9%. Median TTP was 5.8 months (95% CI 4.03-7.83); 29 patients had died. Median OAS was 15.9 months (95% CI 8.8-21.9). Toxicity was mild. CONCLUSIONS The regimen constituted by 5FU modulated by MTX (bolus administration) and FA (continuous infusion) is active as second-line treatment of metastatic colorectal cancer.

Abstract
BACKGROUND DNA damage caused by platinum agents is frequently followed by induction of topoisomerase I, providing a rationale for use of platinum-based compounds with topoisomerase I inhibitors. MATERIALS AND METHODS We studied the effect of a sequential schedule of oxaliplatin on day I and topotecan on days 2-5, in human colon and ovarian cancer cells in vitro, in nude mice bearing human cancer xenografts and finally in cancer patients in a phase I trial. RESULTS We demonstrated a supra-additive effect of this combination on inhibition of colony formation and induction of apoptosis in vitro. We then demonstrated that the two agents in combination markedly inhibit tumor growth in nude mice. We translated these results into a clinical setting, conducting a phase I study in cancer patients with oxaliplatin 85 mg/m2 on day 1 and topotecan at doses escalating from 0.5 to 1.5 mg/m2 on days 2-5. Sixty cycles of treatment were administered to 18 patients affected prevalently by ovarian and colorectal cancer. Combination with topotecan 1.5 mg/m2 caused a dose-limiting toxicity. Therefore the maximum tolerated dose of topotecan was 1.25 mg/m2, at which six patients experienced a mild hematological and gastrointestinal toxicity. We also obtained evidence of clinical activity, particularly in ovarian cancer. CONCLUSIONS Our results provide a solid biological and clinical rationale for a phase II trial at the recommended doses of oxaliplatin 85 mg/m2 and topotecan 1.25 mg/m2, possibly in ovarian cancer patients.

Abstract
PURPOSE Protein kinase A type I (PKAI) and the epidermal growth factor receptor (EGFR) play a role in neoplastic transformation and interact with each other in transducing mitogenic signals. We developed different PKAI and EGFR inhibitors, demonstrating their cooperation with cytotoxic drugs and the therapeutic potential of the combined blockade of PKAI and EGFR. In this study, we investigated the effect of orally active PKAI and EGFR inhibitors in combination with a novel taxane. EXPERIMENTAL DESIGN We combined a hybrid PKAI antisense oligonucleotide sequence (AS-PKAI), the EGFR inhibitor ZD1839 (Iressa), and the taxane IDN5109, studying their effect on human cancer growth, apoptosis, and angiogenesis and measuring vascular endothelial growth factor (VEGF) expression and vessel formation in vitro and after oral administration in nude mice. RESULTS We demonstrated cooperative growth inhibitory and proapoptotic effects and inhibition of VEGF expression with any combination of two drugs and a marked synergistic effect when all three agents were combined. Oral administration of AS-PKAI, ZD1839, and IDN5109 in combination to nude mice caused a remarkable antitumor effect with no histological evidence of tumors in 50% of mice 5 weeks after treatment withdrawal, accompanied by complete suppression of vessel formation and VEGF expression. CONCLUSION This is the first demonstration of the cooperative antitumor and antiangiogenic activity of three novel agents that block multiple signaling pathways after oral administration. Because all agents are under clinical evaluation in cancer patients, our results provide a rationale to translate this feasible therapeutic strategy in a clinical setting.

Abstract
Protein kinase A type I (PKAI) plays a key role in neoplastic transformation, conveys mitogenic signals from different sources, and is overexpressed in the majority of human tumors. Inhibition of PKAI by different tools results in cancer-cell growth inhibition in vitro and in vivo. We and others have recently shown that a novel class of mixed-backbone oligonucleotides targeting the PKAI subunit RIalpha exhibits improved pharmacokinetic properties and antitumor activity accompanied by increased apoptosis in several human cancer types in vitro and in vivo. The role of bcl-2 in the control of apoptosis has been widely documented, and the inhibition of bcl-2 expression and function may have important therapeutic implications. In fact, oligonucleotides antisense bcl-2 have shown antitumor activity in animal models and have successfully completed early clinical trials. Recent studies have demonstrated a direct role of PKA in the regulation of the bcl-2-dependent apoptotic pathway. Therefore, we have investigated the combined blockade of PKA and bcl-2 by antisense strategy as a potential therapeutic approach. The novel hybrid DNA/RNA mixed-backbone oligonucleotide antisense RIalpha (AS RIalpha) in combination with the antisense bcl-2 (AS bcl-2), cooperatively inhibited bcl-2 expression and soft agar growth and induced apoptosis in different human cancer cell lines. p.o. administration of AS RIalpha in combination with i.p. AS bcl-2 caused a marked antitumor effect and a significant prolongation of survival in nude mice bearing human colon cancer xenografts. Moreover, histochemical analysis of tumor specimens showed inhibition of RIalpha and Ki67 expression, inhibition of angiogenesis, and parallel induction of apoptosis in vivo. The results of our study imply an interaction between the PKA and bcl-2 signaling pathways and, because both antisenses have now entered Phase II trials, provide the rationale to translate this novel therapeutic strategy in a clinical setting.

Abstract
We have constructed a series of 22 phosphorothioate 20-mer antisense oligonucleotides directed against different regions of the human (EGFR) mRNA. Treatment with EGFR antisense oligonucleotides showed a dose-dependent inhibition of human GEO colon cancer cell growth in soft agar. Western blot analysis demonstrated a significant reduction in EGFR expression after treatment with each EGFR antisense oligonucleotide. The ability to inhibit GEO anchorage-independent growth, however, varied among the EGFR antisense sequences with an IC(50) ranging between 0.5 and 3.5 microM. Two of these antisense oligonucleotides targeting the regions between 2457-2476 and 614-4633 bases of the human EGFR mRNA have been modified as hybrid DNA/RNA mixed backbone oligonucleotides (MBO) to examine their anticancer properties in vivo. The 2 EGFR antisense MBOs retained the same biological properties of the fully phosphorothioate EGFR antisense oligonucleotides targeting the same EGFR mRNA sequences, such as blocking EGFR synthesis, inhibiting cell growth and enhancing programmed cell death in human cancer cell lines that express functional EGFRs. Furthermore, a potentiation in the growth inhibitory effect on GEO cancer cells was observed after treatment with these EGFR antisense MBOs in combination with cytotoxic drugs, including cisplatin, doxorubicin, paclitaxel, or topotecan. These results show the antiproliferative activity of specific EGFR antisense oligonucleotides and allow to identify novel EGFR antisense MBOs that deserve further evaluation as potential selective anticancer agents alone or in combination with cytotoxic drugs in human carcinomas that express functional EGFRs.

Abstract
The transforming growth factor-alpha/epidermal growth factor receptor (TGF-alpha-EGFR) autocrine pathway, which is involved in the development and the progression of human epithelial cancers, controls, in part, the production of angiogenic factors. These angiogenic factors, including vascular endothelial growth factor (VEGF) and basic fibroblast growth factor (bFGF), are secreted by cancer cells to stimulate normal endothelial cell growth through paracrine mechanisms. ZD1839 (Iressa) is a p.o.-active, selective EGFR-tyrosine kinase inhibitor (TKI) in clinical trials in cancer patients. In this study, we evaluated the antiangiogenic and antitumor activity of ZD1839 in human colon (GEO, SW480, and CaCo2), breast (ZR-75-1 and MCF-7 ADR), ovarian (OVCAR-3), and gastric (KATO III and N87) cancer cells that coexpress TGF-alpha and EGFR. ZD1839 treatment determined a dose- and time-dependent growth inhibition accompanied by the decrease of VEGF, bFGF and TGF-alpha production in vitro. Treatment of immunodeficient mice bearing well-established, palpable GEO xenografts with ZD1839 determined a cytostatic dose-dependent tumor growth inhibition. Immunohistochemical analysis of GEO tumor xenografts after ZD1839 treatment revealed a significant dose-dependent reduction of TGF-alpha, bFGF, and VEGF expression in cancer cells and of neoangiogenesis, as determined by microvessel count. Furthermore, the antitumor activity of ZD1839 was potentiated in combination with the cytotoxic drug paclitaxel in GEO tumor xenografts. Tumor regression was observed in all mice after treatment with ZD1839 plus paclitaxel, and it was accompanied by a significant potentiation in inhibition of TGF-alpha, VEGF, and bFGF expression with a few or no microvessels. Furthermore, 6 of 16 mice bearing well-established, palpable GEO xenografts had no histological evidence of GEO tumors at the end of treatment with ZD1839 plus paclitaxel. These results demonstrate that the antitumor effect of ZD1839 is accompanied by inhibition in the production of autocrine and paracrine growth factors that sustain autonomous local growth and facilitate angiogenesis, and that this effect can be potentiated by the combined treatment with certain cytotoxic drugs, such as paclitaxel.

Abstract
MDM2 is over-expressed in several human tumors. Its product is a negative-feedback regulator of p53, which interferes with the control of cell proliferation and apoptosis, interacting not only with p53 but also with retinoblastoma (Rb) and E2F. Moreover, mutations in the ARF-Ink4a locus may also allow MDM2 to override p53 functions. In this study, we have used a novel oligonucleotide anti-sense MDM2, with mixed-backbone structure and demonstrate that it causes inhibition of MDM2 expression, induction of both p53 and p21/WAF1 expression and a dose-dependent, growth-inhibitory effect in human GEO colon-cancer cells. We also show that anti-sense MDM2 has a co-operative growth-inhibitory effect with different classes of cytotoxic drugs acting by different mechanisms. Moreover, anti-sense MDM2 induces apoptosis and markedly enhances the apoptotic activity of different cytotoxic drugs. Finally, we show that anti-sense MDM2 has anti-tumor activity in vivo in nude mice bearing GEO xenografts and potentiates the anti-tumor effect of cytotoxic drugs. Indeed, despite the short treatment period, the combination of anti-sense MDM2 and cytotoxic drugs causes a marked delay in tumor growth and prolongation of mice survival, lasting several months after treatment cessation. The anti-tumor effect is associated with inhibition of MDM2 expression in tumor specimens of animals treated with anti-sense MDM2, alone or in combination with a cytotoxic drug. Our results provide the rationale for development of a novel mixed-backbone anti-sense MDM2 into a clinical setting in therapeutic combination strategies with conventional cytotoxic drugs.

Abstract
Recent studies have suggested that selective inhibition of mitogenic pathways may improve the antitumor activity of ionizing radiation. The epidermal growth factor receptor (EGFR) is overexpressed and is involved in autocrine growth control in the majority of human carcinomas. Protein kinase A type I (PKAI) plays a key role in neoplastic transformation and is overexpressed in cancer cells in which an EGFR autocrine pathway is activated. We used two specific inhibitors of EGFR and PKAI that are under clinical evaluation in cancer patients: C225, an anti-EGFR chimeric human-mouse monoclonal antibody (MAb); and a mixed-backbone antisense oligonucleotide targeting the PKAI RIalpha subunit (PKAI AS). We tested in human colon cancer (GEO) and ovarian cancer (OVCAR-3) cell lines the antiproliferative activity of MAb C225 and/or PKAI AS in combination with ionizing radiation. In vivo antitumor activity was evaluated in nude mice bearing established GEO xenografts. Dose-dependent inhibition of soft agar growth was observed in both cancer cell lines with ionizing radiation, C225, or PKAI AS oligonucleotide. A cooperative antiproliferative effect was obtained when cancer cells were treated with ionizing radiation followed by MAb C225 or PKAI AS oligonucleotide. This effect was observed at all doses tested in both GEO and OVCAR-3 cancer cell lines. A combination of the three treatments at the lowest doses produced an even greater effect than that observed when two modalities were combined. Treatment of mice bearing established human GEO colon cancer xenografts with radiotherapy (RT), MAb C225, or PKAI AS oligonucleotide produced dose-dependent tumor growth inhibition that was reversible upon treatment cessation. A potentiation of the antitumor activity was observed in all mice treated with RT in combination with MAb C225 or PKAI AS oligonucleotide. Long-term GEO tumor growth regression was obtained following treatment with ionizing radiation in combination with MAb C225 plus PKAI AS oligonucleotide, which produced a significant improvement in survival compared with controls (P < 0.001), the RT-treated group (P < 0.001), or the group treated with MAb C225 plus PKAI AS oligonucleotide (P < 0.001). All mice of the RT + MAb C225 + PKAI AS group were alive 26 weeks after tumor cell injection. Furthermore, 50% of mice in this group were alive and tumor-free after 35 weeks. This study provides a rationale for evaluating in cancer patients the combination of ionizing radiation and selective drugs that block EGFR and PKAI pathways.

Abstract
BACKGROUND p53 and bcl-2 are two key genes involved in cell cycle and cell death regulation. Altered expression or mutation of these genes has been found in human cancers and also has been identified in clear cell renal carcinoma (RCC). Their role in RCC progression, however, is still unclear. By contrast, the prognostic significance of ploidy and S-phase fraction (SPF) have been studied extensively in RCC. To better characterize the biologic role of p53 and bcl-2 oncoproteins in RCC, we offer a multisample correlative analysis of the expression of these two proteins with ploidy and SPF. METHODS Ploidy and SPF along with p53 and bcl-2 expression were analyzed in 296 specimens, selected by multiple sampling of 33 consecutive operable RCCs. The expression of p53 and bcl-2 proteins was studied by immunohistochemistry, and SPF and tumor ploidy were studied by flow cytometry. RESULTS In our study, 4 of 32 (12.5%) were found to be diploid, and 28 of 32 (87.5%) cases showed an abnormal DNA content. Among the aneuploid tumors, 14 of 28 (50%) were multiploid. Heterogeneous DNA content was detected in 21 of 32 (65.6%) tumors and was correlated with the more advanced Robson stage tumor (P = 0. 03). Intratumor heterogeneity also was detected for p53 and bcl-2 protein expression. Expression of p53 protein correlated with the lack of bcl-2 protein expression (P = 0.0032), aneuploidy (P < 0. 0001), and high SPF (P = 0.0006), whereas bcl-2 expression was associated with a normal DNA content (P < 0.0001) and low SPF (P = 0. 035). CONCLUSIONS Within each RCC, p53 and bcl-2 expression is markedly heterogeneous. Our results depicted a scenario in which bcl-2 protein, expressed by normal renal parenchyma, is still present in euploid cell clones of RCC but disappears during the progression of renal neoplasm toward a more aggressive phenotype characterized by overexpression of p53 protein, aneuploidy, and high SPF.

Abstract
BACKGROUND Prognosis of advanced ovarian cancer is unsatisfactory. Chemotherapy can be intensified combining active drugs at their highest possible doses. PATIENTS AND METHODS In this phase I/II trial, 77 untreated patients received escalating doses of paclitaxel (135, 155, 175, 195 and 215 mg/m2, infused over 3 hours) with carboplatin (AUC 3.6) and cisplatin (60 mg/m2). Nine, 16, 13, 8 and 3 patients were treated at the five levels, respectively. A further 28 patients were treated at the maximum tolerable dose (MTD). RESULTS Dose-limiting toxicities (one WHO grade 3 constipation, one grade 2 prolonged peripheral neurotoxicity and one grade 3 cardiac toxicity) occurred at 215 mg/m2 in 3 out of 3 patients. MTD was reached at level 4 paclitaxel dose (195 mg/m2). Response was evaluated in 62 patients. A complete response was achieved in 23 patients (37.1%-95% CI 25.2-50.3), including 16 (25.8%) pathological and partial response in 28 (45.2%), for an overall response rate of 82.3% (95% exact CL: 70.5%-90.8%). The probability of response was affected by the degree of initial debulking (p = 0.002) and not by the paclitaxel dose. In patients with stage III-IV disease, median progression-free survival was 17 months (95% CI 14-25). After a median follow-up of 28 months, median survival had not been reached; 2-year estimated survival was 67%. CONCLUSION Paclitaxel can be safely given at the dose of 195 mg/m2 in combination with carboplatin (AUC 3.6) and cisplatin (60 mg/m2). This combination is active and safe and could be considered in clinical settings requiring intensive short treatment.

Abstract
Angiogenesis plays a key role in tumor growth and metastasis. The transforming growth factor alpha (TGF-alpha)-epidermal growth factor receptor (EGFR) autocrine pathway controls in part the production of angiogenic factors such as vascular endothelial growth factor (VEGF) and basic fibroblast growth factor (bFGF) in cancer cells. In this study, we have evaluated the antiangiogenic and antitumor activity of monoclonal antibody (MAb) C225, an anti-EGFR chimeric human-mouse MAb, alone and in combination with a human VEGF antisense (AS) 21-mer phosphorothioate oligonucleotide (VEGF-AS) in human GEO colon cancer cells. MAb C225 treatment determined a dose-dependent inhibition of VEGF, bFGF, and TGF-alpha production by GEO cells in vitro. Treatment with VEGF-AS caused a selective inhibition in VEGF expression by GEO cells in vitro. Treatment of immunodeficient mice bearing established, palpable GEO xenografts for 3 weeks with VEGF-AS or with MAb C225 determined a cytostatic reversible inhibition of tumor growth. In contrast, a prolonged inhibition of tumor growth was observed in all mice treated with the two agents, in combination with a significant improvement in mice survival compared with controls (P < .001), to MAb C225 (P < .001), or to VEGF-AS (P < .001) treated mice. All mice died within 4, 6, and 8 weeks after tumor cell injection in the control, VEGF-AS and MAb C225 groups, respectively. In contrast, 50% of mice treated with the combination of VEGF-AS and MAb C225 were alive at 13 weeks. Ten % of mice treated with VEGF-AS plus MAb C225 were alive at 20 weeks and had no histological evidence of GEO tumors. Immunohistochemical analysis of GEO tumor xenografts demonstrated a significant reduction of VEGF expression after treatment with VEGF-AS with a parallel reduction in microvessel count. MAb C225 treatment determined a reduction in the expression of VEGF, bFGF, and TGF-alpha with a reduction in microvessel count. Finally, a significant potentiation in inhibition of VEGF expression and little or no microvessels were observed in GEO tumors after the combined treatment with the two agents.

Abstract
Gemcitabine and 5-fluorouracil are the only two compounds with reproducible activity against advanced pancreatic cancer (APC). We have evaluated a novel combination of gemcitabine and 5-fluorouracil on the clinical benefit response (CBR) end point. Eleven consecutive patients with symptomatic APC were entered in a two-stage phase II trial. Gemcitabine was administered by intravenous (i.v.) bolus injection at the dose of 1,000 mg m(-2) on days 1, 8, 15 and 5-fluorouracil 500 mg m(-2) was given by continuous i.v. infusion on days 1-5. Treatment was repeated every 28 days. A CBR was achieved in 7/11 patients. The mean time to loss of CBR was 26.5 weeks (range 14-18, median 22). Toxicity was mild and no APC patient experienced WHO grade 3 toxicity. The gemcitabine/5-fluorouracil combination is well tolerated and produces a symptomatic relief in the majority of APC patients.

Abstract
Protein kinase A type I (PKAI) transduces mitogenic signals from different growth factors and oncogenes and is overexpressed in the majority of human cancers. We and other investigators previously have reported that different PKAI inhibitors, including antisense oligonucleotides, have antitumor activity. In this study, we used a novel hybrid DNA/RNA mixed-backbone oligonucleotide (MBO) targeting the PKAI subunit RIalpha. We demonstrated that after oral administration, the MBO antisense RIalpha inhibited the growth of human colon cancer xenografts in nude mice and showed a cooperative antitumor effect with Taxol, which outlasted treatment withdrawal and significantly prolonged survival of mice compared with untreated controls or to single-agent-treated mice. Immunohistochemical analysis of tumor specimens showed inhibition of target protein RIalpha and of growth factor expression along with a marked inhibition of angiogenesis and an increase in p27 expression. In conclusion, a novel MBO that targets PKAI, administered p.o., is effective and cooperates with the anticancer drug Taxol on both tumor growth and expression of factors involved in the control of cell proliferation, cell cycle, and angiogenesis. Because the MBO described has completed a phase I trial involving i.v. injection in cancer patients, these results provide the biological rationale of its activity after oral administration and may be translated into a therapeutic strategy in a clinical setting.

Abstract
Transforming growth factor alpha (TGF-alpha) is an autocrine growth factor for human cancer. Overexpression of TGF-alpha and its specific receptor, the epidermal growth factor receptor (EGFR), is associated with aggressive disease and poor prognosis. The EGFR has been proposed as a target for anticancer therapy. Compounds that block ligand-induced EGFR activation have been developed. ZD-1839 (Iressa) is a p.o.-active, quinazoline derivative that selectively inhibits the EGFR tyrosine kinase and is under clinical development in cancer patients. The antiproliferative activity of ZD-1839 alone or in combination with cytotoxic drugs differing in mechanism(s) of action, such as cisplatin, carboplatin, oxaliplatin, paclitaxel, docetaxel, doxorubicin, etoposide, topotecan, and raltitrexed, was evaluated in human ovarian (OVCAR-3), breast (ZR-75-1, MCF-10A ras), and colon cancer (GEO) cells that coexpress EGFR and TGF-alpha. ZD-1839 inhibited colony formation in soft agar in a dose-dependent manner in all cancer cell lines. The antiproliferative effect was mainly cytostatic. However, treatment with higher doses resulted in a 2-4-fold increase in apoptosis. A dose-dependent supra-additive increase in growth inhibition was observed when cancer cells were treated with each cytotoxic drug and ZD-1839. The combined treatment markedly enhanced apoptotic cell death induced by single-agent treatment. ZD-1839 treatment of nude mice bearing established human GEO colon cancer xenografts revealed a reversible dose-dependent inhibition of tumor growth because GEO tumors resumed the growth rate of controls at the end of the treatment. In contrast, the combined treatment with a cytotoxic agent, such as topotecan, raltitrexed, or paclitaxel, and ZD-1839 produced tumor growth arrest in all mice. Tumors grew slowly for approximately 4-8 weeks after the end of treatment, when they finally resumed a growth rate similar to controls. GEO tumors reached a size not compatible with normal life in all control mice within 4-6 weeks and in all single agent-treated mice within 6-8 weeks after GEO cell injection. In contrast, 50% of mice treated with ZD-1839 plus topotecan, raltitrexed, or paclitaxel were still alive 10, 12, and 15 weeks after cancer cell injection, respectively. These results demonstrate the antitumor effect of this EGFR-selective tyrosine kinase inhibitor and provide a rationale for its clinical evaluation in combination with cytotoxic drugs.

Abstract
Second-line treatment of patients with metastatic breast cancer resistant to anthracyclines is an important clinical issue. The aim of the present two-stage phase II study was to evaluate activity and toxicity of vinorelbine + mitomycin C (VM) in such patients. Fifty-five patients were entered and received vinorelbine 30 mg/m(2) on days 1 and 8 + mitomycin C 10 mg/m(2) on day 1, every 4 weeks, up to 9 cycles. Two complete and 23 partial responses were observed for an overall response rate of 45.4% (95% CI 32.0-59.4). Median survival was 13 months and probability of surviving after a 1-year follow-up was 58%. Toxicity was never life-threatening, but G-CSF was used in 45% of cycles to contrast neutropenia that was the most frequent side effect. These results are consistent with previous studies and strongly support VM being considered among the optimal polychemotherapy regimens for second-line treatment of metastatic breast cancer in clinical practice; for clinical research aims, VM should be used as control arm for randomized trials evaluating the activity of new drugs against breast cancer.

Abstract
We have tested the sensitivity of human MCF-10A mammary epithelial cells and of their transformed derivatives overexpressing an activated c-Ha-ras gene (MCF-10A Ha-ras cells), the c-erbB-2 gene (MCF-10A c-erbB-2 cells) or both genes (MCF-10A HE cells) to different cytotoxic drugs. As compared with parental MCF-10A cells, the transformed cells exhibited an increased sensitivity to topoisomerase I- and topoisomerase II-inhibitors, and to platinum-derivatives with a 2- to 10-fold reduction in IC(50) values. A remarkable difference in sensitivity was observed following treatment with taxanes. While MCF-10A Ha-ras cells showed an increased sensitivity, MCF-10A c-erbB-2 and MCF-10A HE cells exhibited a relative resistance to taxol and taxotere, with an approximately 3.5- to 6.5-fold higher IC(50) as compared with MCF-10A cells suggesting that c-erbB-2 overexpression has a dominant effect compared with an activated c-Ha-ras gene. The type I cAMP-dependent protein kinase (PKAI) is overexpressed in cancer cells. Inhibition of PKAI by antisense oligonucleotides targeting its RIalpha regulatory subunit results in cancer cell growth inhibition. To evaluate the effect of blocking PKAI on MCF-10A cell sensitivity to taxanes, we treated these cells with taxol or taxotere in combination with a PKAI antisense oligonucleotide. Treatment with this agent, but not with a control scramble sequence, was able to overcome the effect of c-erbB-2 overexpression on MCF-10A cell sensitivity to taxol and taxotere, with a 20- to 40-fold shift in the IC(50) values for the 2 drugs.

Abstract
Somatostatin analogs are promising agents in the treatment of medullary thyroid carcinoma. We have evaluated the effects of the slow release somatostatin analog lanreotide in combination with interferon-alpha2b in seven patients with advanced and symptomatic medullary thyroid carcinoma. The frequency and intensity of daily flushing episodes and bowel movements, the intensity of fatigue, weight, performance status, calcitonin levels, and change in tumor masses were recorded before and during treatment. No objective complete or partial responses were recorded. However, disease stabilization and minor tumor regression were observed in three of seven and two of seven patients, respectively. The number and intensity of bowel movements and flushing episodes decreased in five of six and two of two patients, respectively. Decrease in fatigue and improvement in performance status were observed in five of seven and six of seven patients, respectively. Weight gain was recorded in three of four patients. Plasma levels of calcitonin decreased significantly in six of seven patients. Clinical benefit, evaluated by a structured algorithm, was achieved in six of seven patients and was coupled with a decrease of 50% or more in serum calcitonin levels in three of seven patients. In conclusion, the combination of lanreotide with interferon had a major impact on clinical symptoms and was well tolerated.

Abstract
From January 1992 to December 1995, 129 patients with previously untreated non-Hodgkin's lymphoma were randomised in a phase III multicenter trial to receive CEOP-B/VIMB or ProMACE-CytaBOM. Eligibility criteria included intermediate or high grade lymphoma (follicular large cell, diffuse small cleaved-cell, diffuse mixed, diffuse large-cell and immunoblastic) with an Ann Arbor stage II bulky, III or IV. All patients entered into the study were considered evaluable according to intent to treat analysis. At a median follow-up of 60 months there were no significant differences between the treatment response rates [82% (60%CR) for CEOP-B/VIMB vs. 81% (69% CR) for ProMACE-CytaBOM]. Conversely, with regard to disease-free survival, a significant difference was observed between the two treatment arms (42% for CEOP-B/VIMB vs. 24% for ProMACE-CytaBOM at 5 years; p=0.046). However, this difference did not translate in a significant difference in overall survival (45% vs. 39% at 5 years). Moreover, when response rates and outcome were analysed for different prognostic subgroups according to International Prognostic Index, no significant differences were observed between the treatment groups. It is important to note that neither regimen was able to improve outcome of poor risk patients who fared badly with both treatments (median survival 9 and 8 months respectively). Toxicity was also similar in both treatments with grade 3-4 leukopenia observed in 39% and 47% of cases and grade 3-4 thrombocytopenia in 24% and 27% of cases respectively. In conclusion, in this study CEOP-B/VIMB was not superior to ProMACE-CytaBOM in aggressive lymphomas and the alternating strategy failed to improve outcome of poor risk patients in which newer more aggressive treatments are needed.

Abstract
Protein truncation test (PTT) and single-strand conformation polymorphism (SSCP) assay were used to scan the BRCA1 and BRCA2 genes in 136 unrelated Italian breast/ovarian cancer patients. In the sample tested, BRCA1 and BRCA2 equally contributed to site-specific breast cancer patients who reported one to two breast cancer-affected first-/ second-degree relative(s) or who were diagnosed before age 40 years in the absence of a family history of breast/ovarian cancer. BRCA1 and BRCA2 mutations were mostly found in patients with disease diagnosis before and after age 50 years, respectively. Moreover, in cases with familial clustering of site-specific breast cancer, BRCA1 mostly accounted for tumours diagnosed before age 40 years and BRCA2 for tumours diagnosed after age 50 years. The BRCA1 and BRCA2 mutation spectrum was consistent with a lack of significant founder effects in the sample of patients studied.

Abstract
We describe a case of intracranial haemangioendothelioma in a 20-year old female patient who presented severe neurological symptoms and relapsed after two surgical interventions. The patient was treated with low doses of recombinant interferon alpha-2b (1 MUI three times a week) after surgical resection which led to recovery of daily function and work activity. To our knowledge, this is the ninth patient reported with intracranial hemangioendothelioma, but the only one having diffuse and painful bone metastases resolved by treatment with interferon. After 30 months the patient is free from symptoms and recurrence. The effectiveness shown by recombinant interferon alpha-2b against vascular neoplasms prompted us to look for the possible biological basis of such a property.

Abstract
Tumor-node-metastasis (TNM) staging is the standard system for the estimation of prognosis of breast cancer patients. However, this system does not exploit information yielded by markers of the biological aggressiveness of breast cancer and is clearly unsatisfactory for optimal-treatment decision-making and for patient counseling. We have developed a prognostic model, based on a few routinely evaluated prognostic variables, that produces quantitative estimates for risk of relapse of individual breast cancer patients. We used data concerning 2441 of 2990 consecutive breast cancer patients to develop an artificial neural network (ANN) for the prediction of the probability of relapse over 5 years. The prognostic variables used were: patient age, tumor size, number of axillary metastases, estrogen and progesterone receptor levels, S-phase fraction, and tumor ploidy. Performances of the model were evaluated in terms of discrimination ability and quantitative precision. Predictions were validated on an independent series of 310 patients from an institution in another country. The ANN discriminated patients according to their risk of relapse better than the TNM classification (P = 0.0015). The quantitative precision of the model's estimates was accurate and was confirmed on the series from the second institution. The 5-year relapse risk yielded by the model varied greatly within the same TNM class, particularly for patients with four or more nodal metastases. The model discriminates prognosis better than the TNM classification and is able to identify patients with strikingly different risks of relapse within each TNM class.
