Primary chemotherapy with gemcitabine, epirubicin and taxol (GET) in operable breast cancer: a phase II study.

This trial was conducted to assess the activity and tolerability of the gemcitabine, epirubicin, taxol triplet combination in patients with operable breast cancer. After core biopsy, 43 women with stage II-IIIA breast cancer were treated with gemcitabine 1000 mg m(-2) over 30 min on days 1 and 4, epirubicin 90 mg m(-2) as an intravenous bolus on day 1, and taxol 175 mg m(-2) as a 3-h infusion on day 1, every 21 days for four cycles. The primary end point was the percentage of pathological complete responses (pCR) in the breast; secondary end points were tolerability, clinical response rates, overall and progression-free survival, tumour biomarkers before and after primary chemotherapy (PCT). All patients were included in safety and survival analyses; 41 eligible patients were evaluated for response. The overall clinical response rate was 87.8% (95% CI 77.8-97.8), with 26.8% complete responses (95% CI 13.3-40.3). A pCR in the breast was observed in six patients (14.6%; 95% CI 3.8-25.4); 15 patients (36.6%; 95% CI 21.9-51.3) had negative axillary lymph nodes. Grade 4 neutropenia was observed in 67.4% of the patients; febrile neutropenia occurred in 1.9% of cycles (granulocyte colony-stimulating factor was used in 3.2% of the cycles to shorten the duration of neutropenia). A statistically significant difference between Mib-1 at baseline (> or =20% in 71.4% of the patients) and at definitive surgery (28.6%, P < 0.05) was observed. The gemcitabine, epirubicin, taxol regimen is active and well tolerated as PCT for operable breast cancer. This combination allows the administration of full doses of active agents with a low incidence of febrile neutropenia.

A Randomized Study of Epithelial Ovarian Cancer: Is Chemotherapy Useful after Complete Remission?

Objective. The aim of this study is to verify whether consolidation chemotherapy with Cisplatin improves disease-free survival and/or overall survival in patients affected by epithelial ovarian cancer.Methods. A multicenter study examined 122 randomized patients in complete remission as judged by laparoscopy or laparotomy following first-line chemotherapy consisting of ACy (Adriamycin + Cyclophosphamide), PCy (Cisplatin + Cyclophosphamide), or Mitoxantrone + Carboplatin. Sixty-one of these patients were treated with 3 cycles of 5-Fluorouracil (FU) 500 mg/m2 for 5 days followed by Cisplatin at 100 mg/m2 on the 6th or 7th day every 28 days; the other 61 received no further treatment (nihil group).Results. Sixty patients in the Cisplatin arm were evaluable. There were 36 relapses in the FU+Cisplatin arm and 30 in the nihil arm. Peritoneal relapses were 25% for Cisplatin treatment vs. 16.4 % for nihil. There were 29 deaths in the Cisplatin arm vs. 27 for nihil. Median overall survival time (95 months with Cisplatin vs. 96 months in the nihil group) and median disease-free survival (66 months with Cisplatin vs. 73 in the nihil group) were similar in both arms (p=0.66 and p=0.41, respectively). There were no significant differences in tumor stage and grade between the two arms. Seven patients presented a second neoplasm during follow-up: six in the nihil arm, but only one patient in the Cisplatin arm. Death in these patients was due to the second neoplasm and not to progression of ovarian cancer.Conclusion. Three courses of additional platinum+FU treatment after five cycles of first-line chemotherapy without FU produced no increase in overall survival or disease-free survival.

Multicentric phase II trial of gemcitabine plus epirubicin plus paclitaxel as first-line chemotherapy in metastatic breast cancer.

In this phase II, multicentre trial, patients with metastatic breast cancer (MBC) were treated with a combination of gemcitabine, epirubicin and paclitaxel (GET). The primary objective of this study was to determine the tolerability and activity in terms of complete responce (CR) and overall response rate of the GET combination in this patient population. Patients with no prior treatment for MBC, and at least one bidimensionally measurable lesion received gemcitabine 1000 mg m(-2) intravenously (i.v.) over 30 min on days 1 and 4, followed by epirubicin i.v. at 90 mg m(-2) on day 1, and paclitaxel 175 mg m(-2) over 3 h on day 1, every 21 days, up to eight courses. From May 1999 to June 2000, 48 patients were enrolled from seven Italian institutions. A total of 297 chemotherapy courses were administered with a median of six cycles patient(-1) (range 1-8). Seven patients (15%) obtained CR and 27 patients (56%) had partial responce, for an overall response rate of 71% (95% CI: 58.3-83.7). After a median follow-up of 23.7 months (range 7.0-34.4), median progression-free survival was 10.5 months (95% CI: 9.2-11.7), and median overall survival 25.9 months. The main haematological toxicity consisted of grade 3 or 4 neutropenia that occurred in 62% of cycles (22% grade 4 and 40% grade 3). The GET combination is active and well tolerated as first-line chemotherapy for MBC.

Hepatic intra-arterial chemotherapy (HIAC) of high dose mitomycin and epirubicin combined with caval chemofiltration versus prolonged low doses in liver metastases from colorectal cancer: a prospective randomized clinical study.

A multicenter randomized study comparing high dose of mitomycin and epirubicin given as hepatic intra-arterial chemotherapy (HIAC) combined with caval chemofiltration (CF) versus low doses of the same drugs in unresectable liver metastases from colorectal cancer showed a significant improvement in the survival rate of the 20 patients treated with high dose compared to the 22 patients treated with low doses with a 1 year survival of 69% vs 39%. The median survival was 17 vs 11 months and the responses were 65% vs 33%. Toxicity was colangitis in 50% of patients considered. The extrahepatic progression was similar in the two groups (7/20 vs 8/22).

Phase II study of carboplatin in patients with advanced or recurrent endometrial carcinoma. A trial of the EORTC Gynaecological Cancer Group.

The aim of this study was to investigate the efficacy and toxicity of carboplatin given as monotherapy in endometrial adenocarcinoma. Cisplatin is one of the most active drugs in gynaecological cancer types, but at the cost of an associated high toxicity. In this high-risk population of endometrial cancer patients, it is necessary to have chemotherapy regimens with a low toxicity. Patients eligible for this study were those with histologically-confirmed endometrial adenocarcinoma with evidence of recurrent and/or metastatic disease. Carboplatin was administered every 4 weeks as a first- (dose: 400 mg/m(2)) or second- (dose: 300 mg/m(2)) line chemotherapy. Of the 64 patients who entered the trial, 60 were eligible, 53 patients were evaluable for toxicity and 47 for efficacy. A total of 169 cycles of carboplatin was given with a median of 2 cycles per patient (range 1-11 cycles) to a median cumulative dose of 798 mg/m(2) (range 290-3879 mg/m(2)). No grade 4 toxicity or toxic deaths occurred. White Blood Cell (WBC) toxicity grade 3 was noted five times, mainly in the radiotherapy pre-treated patients. Grade 3 non-haematological toxicity consisted mainly of nausea and vomiting (21%). There was a total of eight responses (3 Complete Responses (CR) and 5 Partial Responses (PR) with an overall response rate (ORR) of 13% (95% Confidence Interval (CI) 6-25). No responses occurred in patients treated with prior chemotherapy. In evaluable patients, the ORR in all patients (n=47) and in those receiving first-line chemotherapy (n=33) were, 17% (95% CI 8-31) and 24% (95% CI 11-42), respectively. After a median follow-up of 379 days, the median duration of response was 488 days (range 141-5303 days) with two very long responses in patients with a CR. Carboplatin has a low toxicity and is active in chemotherapy-naive advanced endometrial carcinoma patients. These results lead us to propose its use in association in first-line chemotherapy in recurrent or advanced endometrial carcinoma patients. The choice of the initial dose can be determined according to whether the patients have received prior radiotherapy treatment.

Doxorubicin versus doxorubicin and cisplatin in endometrial carcinoma: definitive results of a randomised study (55872) by the EORTC Gynaecological Cancer Group.

BACKGROUND: Combination chemotherapy yields better response rates which do not always lead to a survival advantage. The aim of this study was to investigate whether the reported differences in the efficacy and toxicity of monotherapy with doxorubicin (DOX) versus combination therapy with cisplatin (CDDP) in endometrial adenocarcinoma lead to significant advantage in favour of the combination. PATIENTS AND METHODS: Eligible patients had histologically-proven advanced and/or recurrent endometrial adenocarcinoma and were chemo-naïve. Treatment consisted of either DOX 60 mg/m(2) alone or CDDP 50 mg/m2 added to DOX 60 mg/m2, every 4 weeks. RESULTS: A total of 177 patients were entered and median follow-up is 7.1 years. The combination DOX-CDDP was more toxic than DOX alone. Haematological toxicity consisted mainly of white blood cell toxicity grade 3 and 4 (55% versus 30%). Non-haematological toxicity consisted mainly of grade 3 and 4 alopecia (72% versus 65%) and nausea/vomiting (36 % versus 12%). The combination DOX-CDDP provided a significantly higher response rate than single agent DOX (P <0.001). Thirty-nine patients (43%) responded on DOX-CDDP [13 complete responses (CRs) and 26 partial responses (PRs)], versus 15 patients (17%) on DOX alone (8 CR and 7 PR). The median overall survival (OS) was 9 months in the DOX-CDDP arm versus 7 months in the DOX alone arm (Wilcoxon P = 0.0654). Regression analysis showed that WHO performance status was statistically significant as a prognostic factor for survival, and stratifying for this factor, treatment effect reaches significance (hazard ratio = 1.46, 95% confidence interval 1.05-2.03, P = 0.024). CONCLUSIONS: In comparison to single agent DOX, the combination of DOX-CDDP results in higher but acceptable toxicity. The response rate produced is significantly higher, and a modest survival benefit is achieved with this combination regimen, especially in patients with a good performance status.

Elderly ovarian cancer: treatment with mitoxantrone-carboplatin.

OBJECTIVE: Data concerning optimal treatment of elderly patients with ovarian cancer are scanty. The management of ovarian cancer in the aged patient is many-sided: the diagnosis can be difficult and delayed, and aggressive surgery is often not attempted because of concomitant morbidity. We tested a combination of carboplatin and mitoxantrone potentially associated with low toxicity in elderly patients with ovarian cancer. METHODS: Eighty-two patients older than 70 years (median age, 75; range, 70-88) with epithelial ovarian cancer were referred to our multicenter group and enrolled into this pilot study. Carboplatin (JM8) was given at the dose of 230 mg/m2 and mitoxantrone at the dose of 9 mg/m2 every 28 days. RESULTS: Dose-limiting toxicity was represented by 4 cases of thrombocytopenia and 1 case of gastrointestinal toxicity. These 5 episodes occurred in 328 assessable cycles, representing a low toxicity profile (3%). Of the 68 assessable patients, 36 (53%) did not respond to chemotherapy (no change + progressive disease), complete response was observed in 15 (22%), and partial remission was observed in 16 (23.5%), accounting for an overall response rate of 45%. CONCLUSION: The carboplatin-mitoxantrone combination, at the dosage tested in this study, appears to be well tolerated by elderly patients with advanced ovarian cancer and is associated with an acceptable response rate. Optimally debulked patients also showed improved survival when compared with patients with more extensive tumor.

Topoisomerase I inhibitors combination chemotherapy in non-small cell lung cancer.

In the last years, the main topoisomerase I inhibitors (TP1-I) (i.e. topotecan and irinotecan) have been used in combination chemotherapy in non-small cell lung cancer. Several drugs (also alternative to cisplatin) have been used in combination with TP1-I, but to date the higher remission rate obtained with combinations is not translated into a more prolonged survival in comparison with TP1-I given alone. On the other hand, the toxicity of TP1-I combinations is greater than those of TP1-I used alone. The superior efficacy of combinations versus TP1-I used alone remains an open question. Furthermore, the best schedule for TP1-I has not been completely elucidated. Randomised studies are few (only two phase III trials) and only controlled studies will be able to clarify the best TP1-I combination regimen.

D-TRP-6-LHRH (Triptorelin) is not effective in ovarian carcinoma: an EORTC Gynaecological Cancer Co-operative Group Study.

Between March and September 1988, 74 patients with progressive ovarian cancer after prior platinum-based therapy were treated with the luteinizing hormone-releasing hormone (LHRH) agonist Triptorelin (Decapeptyl degrees). Treatment consisted of i.m. injection of 3.75 mg of microencapsulated Triptorelin on days 1, 8 and 28 followed by 4-weekly injections until tumor progression. No objective responses were observed. Eleven out of 68 evaluable patients (16%) had stable disease. The median progression-free survival was 5 months in patients with disease stabilization and 2 months for all evaluable patients. The median survival for patients with disease stabilization was 17 months, whereas for all patients it was 4 months. The treatment was well tolerated; the only reported adverse events were incidental hot flushes. This study showed that the LHRH agonist Triptorelin has only modest efficacy in patients pretreated with platinum-containing chemotherapy.

Preliminary results of combined therapy with topotecan and carboplatin in advanced non-small-cell lung cancer.

Topotecan is a topoisomerase I inhibitor and an analogue of camptothecin with demonstrated activity in small-cell lung cancer. However, less is known about the potential role of topotecan in advanced non-small-cell lung cancer (NSCLC). Platinum-based combination therapy is currently recommended in NSCLC patients presenting with good performance status. Because topotecan demonstrates a novel mechanism of action, its investigation in platinum combinations is warranted. In phase I/II trials of topotecan given as part of a cisplatin-based regimen, significant antitumor activity has been observed, providing the rationale for conducting further studies aimed at assessing survival benefit. However, this combination exhibits sequence dependence, with increasing hematologic toxicity observed when cisplatin is administered on day 1 of a 5-day topotecan course. Cisplatin has been associated with dose-limiting nonhematologic toxicities. Carboplatin exhibits a different toxicity profile compared with cisplatin, which makes it an attractive agent to study in combination. A hypothesis can be made that carboplatin in combination with newer agents such as topotecan might compare favorably with classic cisplatin-based regimens, particularly with respect to efficacy:toxicity ratio. Therefore, a phase II study was initiated to determine the efficacy, toxicity, and safety of carboplatin-topotecan combination in advanced NSCLC. Preliminary results reported here show that topotecan with carboplatin is generally well tolerated with manageable hematologic toxicity. Indirect comparison with cisplatin-topotecan combination suggests a lower incidence of dose-limiting nonhematologic toxicity. Whether or not the carboplatin-topotecan regimen is able to offer tumor response and survival benefit comparable to those observed with cisplatin-based combinations remains to be established.

Phase II study of a combination of cyclophosphamide, adriamycin and cisplatin in advanced fallopian tube carcinoma. An EORTC gynecological cancer group study. European Organization for Research and Treatment of Cancer.

OBJECTIVE: To investigate the clinical activity and toxicity of a combination chemotherapy consisting of cyclophosphamide (C), adriamycin (A) and cisplatin (P) for patients with primary adenocarcinoma of the Fallopian tube having FIGO stage III-IV disease. METHODS: The CAP-regimen consisted of cyclophosphamide 600 mg/m2, adriamycin 45 mg/m2, and cisplatin 50 mg/m2 administered intravenously on day one every 28 days. RESULTS: Twenty-four eligible patients with histologically-confirmed Fallopian tube adenocarcinoma were entered in the trial. Fourteen patients had FIGO stage III, and ten had stage IV disease. The median number of CAP cycles was six. Ten patients had a complete and six had a partial response (response rate: 67%, 95% confidence limits: 45-84%). WHO grade III-IV side-effects included haematological toxicity, nausea/vomiting and alopecia. Furthermore, mild signs of cisplatin-related peripheral neurotoxicity were observed. At a median follow-up of 40 months, nine patients were alive and 15 had died due to malignant disease. The median time to progression was 13 months for all patients. The median overall survival was 24 months and the 1-, 3- and 5-year survival and their 95% confidence limits were 73% (54-92%), 25% (4-46%) and 19% (0-38%), respectively. CONCLUSION: The present data confirm the therapeutic activity of the CAP-regimen in primary Fallopian tube adenocarcinoma. The response rate is moderate and the toxicity profile is acceptable.

Randomized intergroup trial of cisplatin-paclitaxel versus cisplatin-cyclophosphamide in women with advanced epithelial ovarian cancer: three-year results.

BACKGROUND: A randomized trial conducted by the Gynecologic Oncology Group (GOG, study #111) in the United States showed a better outcome for patients with advanced ovarian cancer on the paclitaxel-cisplatin regimen than for those on a standard cyclophosphamide-cisplatin regimen. Before considering the paclitaxel-cisplatin regimen as the new "standard," a group of European and Canadian investigators planned a confirmatory phase III trial. METHODS: This intergroup trial recruited 680 patients with broader selection criteria than the GOG #111 study and administered paclitaxel as a 3-hour instead of a 24-hour infusion; progression-free survival was the primary end point. Patient survival was analyzed by use of the Kaplan-Meier technique. Treatment effects on patient survival were estimated by Cox proportional hazards regression models. All statistical tests were two-sided. RESULTS: The overall clinical response rate was 59% in the paclitaxel group and 45% in the cyclophosphamide group; the complete clinical remission rates were 41% and 27%, respectively; both differences were statistically significant (P =.01 for both). At a median follow-up of 38.5 months and despite a high rate of crossover (48%) from the cyclophosphamide arm to the paclitaxel arm at first detection of progression of disease, a longer progression-free survival (log-rank P =.0005; median of 15.5 months versus 11.5 months) and a longer overall survival (log-rank P =. 0016; median of 35.6 months versus 25.8 months) were seen in the paclitaxel regimen compared with the cyclophosphamide regimen. CONCLUSIONS: There is strong and confirmatory evidence from two large randomized phase III trials to support paclitaxel-cisplatin as the new standard regimen for treatment of patients with advanced ovarian cancer.

BRCA1 and BRCA2 genes: role in hereditary breast and ovarian cancer in Italy.

The heritable defects of BRCA1 and BRCA2 genes have been shown to predispose to breast and ovarian cancers. In a previous report, we analyzed 46 Italian families with breast and/or ovarian cancer for BRCA1 mutations. In the present study, those families and 11 others were screened for BRCA2 mutations; the newly enrolled families were also analyzed for the BRCA1 gene. The coding region and splice boundaries of BRCA2 and BRCA1 genes were assessed by the protein-truncation test and single-strand conformational polymorphism. A total of 20 different mutations were found in 21 families (37%). A total of 9 families (16%) showed mutations in the BRCA1 gene, including the one new mutation identified in this study (5382insC), and 12 families (21%) presented mutations in the BRCA2 gene. BRCA2-mutated families presented breast and ovarian cancers or breast cancers only, whereas most BRCA1-mutated families presented ovarian cancer alone or in association with breast cancer. All the BRCA2 mutations led to a truncated protein: 6 were frameshift mutations, 4 were non-sense mutations and 2 involved the intronic invariant region leading to splice variants. Therefore, in the Italian population, the cumulative proportion of BRCA1 and BRCA2 mutations was within the range observed in other studies (37%), with higher involvement of BRCA2 than of BRCA1. Many families in which no mutations were found presented a very high incidence of breast and/or ovarian cancer. Among the 36 BRCA1 and BRCA2 wild-type families, 24 presented at least 4 cancer cases, indicating the existence of other important predisposing genes.

Pharmacokinetics of oral etoposide in patients with hepatocellular carcinoma.

Etoposide dosage in patients with liver dysfunction remains controversial. Since etoposide has a hepatic component to its clearance (CL) and shows a high degree of protein binding, hepatic impairment could affect etoposide disposition. However, the empiric recommendation that the dose of etoposide be decreased in such patients may reduce systemic exposure and be detrimental to its antitumor activity. To address these issues we studied the pharmacokinetics (PK) of etoposide in patients with hepatocellular carcinoma (HCC) and underlying cirrhosis (n = 17) treated with daily oral etoposide. Unbound etoposide was obtained by ultrafiltration. Etoposide concentrations (total and free drug) were measured by high-performance liquid chromatography (HPLC) and analyzed by noncompartmental equations. The patients had mild or moderate liver dysfunction. Albuminemia was in the normal range for all the patients. Creatininemia was normal in all but two patients. PK results (mean and range) showed that etoposide disposition was unchanged in patients with liver dysfunction. We found slightly high etoposide bioavailability [F, 61% (17-95%)] and clearance [CL, 1.1 (0.7-2.3)l h(-1) m(-2)] resulting in a normal degree of systemic exposure (AUC(oral) 27 microg h ml(-1)). Normal protein binding [PB 93.2% (84.4-98.1%)] contributed to a normal level of exposure to free drug (AUC(f, oral) 1.9 microg h ml(-1)). The distribution volume [V(SS) 8.4 (6.1-13.2) l/m2] and the effective half-life [t1/2eff, 5.1 (3.0-9.6) h] were normal. Median CL and protein binding did not differ in the seven patients with total bilirubin value of > 1.2 mg/dl as compared with the ten patients with total bilirubin levels of < or = 1.2 mg/dl (1.3 versus 1.01 h(-1) m(-2) and 92.5% versus 93.4%, respectively). In agreement with this PK finding, we observed no clinical evidence of increased toxicity in patients with hyperbilirubinemia as compared with patients with normal bilirubinemia (mean WBC decrease 38% versus 47%). The only case of severe (grade 4) hematological toxicity was observed in one patient with reduced glomerular filtration. Since the pharmacological effects of etoposide correlate with the level of systemic exposure to the free drug, our data suggest that no dose reduction is needed in patients with HCC. It is even possible to increase the dose intensity in patients with favorable PK parameters under appropriate hematological and therapeutic drug monitoring.

Cyclophosphamide or ifosfamide in patients with advanced and/or recurrent endometrial carcinoma: a randomized phase II study of the EORTC Gynecological Cancer Cooperative Group.

UNLABELLED: Currently, available chemotherapy regimens for patients with advanced or recurrent endometrial cancer are generally not curative. Thus, there is a need to identify more active single agents in this disease. In this study patients pre-treated and not pre-treated with first line combination chemotherapy were entered into a randomized phase II study of either cyclophosphamide (CYCLO) or Ifosfamide (IFOS). PATIENTS AND METHOD: Sixty one eligible patients with recurrent or metastatic histologically proven, adenocarcinoma of the uterine corpus entered the study. The median age at entry was 62 (range 40-74) years. Twenty patients (33%) had prior hormonal treatment and 31 (51%) prior chemotherapy. CYCLO was given at a dose of 1200 mg/m2 and IFOS at a dose of 5 g/m2. Both drugs were administered i.v. over 24 hours on day one every three weeks. Adequate pre- and post hydration as well as use of Mesna in the Ifosfamide arm were mandatory. RESULTS: A median of two treatment cycles (range 1-12) per patient were given. In the chemotherapy-naive patients, in the CYCLO arm two PRs (RR 14%, C.I. 2-43%) were seen and in the IFOS arm two CRs, two PRs, (RR 25%, C.I. 7-52%) were observed. No responses were seen in pre-treated patients. The duration of responses were: 15+, 7+ months for the CRs, 15+ and 5 months for PRs in IFOS arm and 67+, 4 months in CYCLO arm. The hematological toxicity was dose-limiting and similar in both treatment arms. No serious non hematological toxicities were reported, but a transient increase of the creatinine blood level was seen in two IFOS patients (6%). CONCLUSION: Ifosfamide is an active drug in the treatment of chemotherapy-naive patients with advanced endometrial cancer and its application in currently used (combination) regimens should be considered.

Low incidence of BRCA1 mutations among Italian families with breast and ovarian cancer.

Most familial breast or ovarian cancers are thought to be due to highly penetrant mutations in the predisposing genes BRCA1 and BRCA2. The cloning of these genes has opened a new era for the genetic counseling of women with a family history of breast or ovarian cancer. To estimate the incidence of detectable BRCA1 mutations and to define the eligibility criteria for genetic testing in the Italian population, a total of 53 patients belonging to 46 families clustering multiple cases of breast and/or ovarian cancer were investigated. Seven families presented with ovarian cancer only, 16 had both ovarian and breast cancers, and 23 were characterized by breast cancer only. Using a combination of protein truncation test (PTT) and single strand conformational polymorphism (SSCP) analysis followed, when necessary, by direct sequencing, we found 8 distinct mutations, 2 of these not reported before. Five frameshift and 2 nonsense mutations led to a truncated protein. One mutation was a missense substitution involving a cysteine in the zinc finger domain. One variant creating an ETS binding site in intron I was found but its role was not defined. The percentage of families carrying mutations was 17%. Among the families characterized by ovarian cancer only and by breast and ovarian cancer, the percentage of BRCA1 mutations was 57% and 12.5%, respectively. In contrast, the percentage of altered BRCA1 in families with only breast cancers was 9%. In the 46 Italian families studied, BRCA1 mutations were detected in fewer kindreds than those previously hypothesized based on linkage analysis, especially when these were characterized by breast cancers only. Our results indicate that families with a low number of cancer patients should be referred for BRCA1 genetic testing mainly when ovarian cancer is present.

Expression of folate binding protein as a prognostic factor for response to platinum-containing chemotherapy and survival in human ovarian cancer.

Overexpression of the folate binding protein (FBP) is a common feature in epithelial ovarian cancer, but its prognostic significance is not clearly understood. We investigated whether FBP in epithelial ovarian cancer specimens is a predictor of response to chemotherapy and survival. Between 1990 and 1995, 99 patients with epithelial ovarian cancer underwent primary surgery and were treated with chemotherapeutic regimens including platinum derivatives. First-line chemotherapy was performed in 58 patients with residual disease and in 41 patients without residual disease after primary laparotomy. FBP expression level was determined in frozen specimens by cyto-fluorimetric assay using the MOv 18 monoclonal antibody (MAb). Association of FBP fluorescence index (FI) with clinical characteristics, response to chemotherapy, and survival was studied by univariate and multivariate analysis. In the 58 patients with residual disease after primary surgery, failure to respond to chemotherapy (complete or partial remission) was about 15-fold higher (95% confidence interval, 2.96-77.43) when tumors had FBP FI above the median value (FBP FI = 3.25). FBP FI was not a predictor of survival in the entire series of tumors (99 patients). However, in the subgroup of 58 patients with residual disease after primary surgery, survival analysis confirmed the disadvantage observed with respect to response to chemotherapy in patients expressing FBP FI above the median value (hazard ratio 2.01; 95% confidence interval 0.95-4.24). In conclusion, higher levels of FBP expression might be a predictor of chemotherapy response failure in ovarian cancer. In patients with residual disease after primary surgery, FBP FI could represent a valuable prognostic marker for survival.

Cisplatin-, epirubicin- and paclitaxel-containing chemotherapy in uterine adenocarcinoma.

PURPOSE: To evaluate the toxic effects and antitumour activity of a multidrug regimen with cisplatin, epirubicin and paclitaxel (CEP) as initial therapy in patients with uterine adenocarcinoma. PATIENTS AND METHODS: Forty-nine patients with histologically-confirmed diagnoses of locally advanced, recurrent or metastatic cervical or endometrial adenocarcinoma entered the study. Treatment consisted of epirubicin (E) given at 70 mg/m2 followed by paclitaxel (P) (175 mg/m2 over three hours) and cisplatin (C) (50 mg/m2), repeated every three weeks. Eligibility criteria also included age < or = 75 years, no previous chemotherapy, no previous radiotherapy to the tumour parameters, bidimensionally-measurable lesions, no previous or ongoing cardiac disease, and renal and liver function within normal limits. Complete blood cell counts were repeated weekly, and tumor response was assessed every three cycles. A maximum of eight courses was administered in responding patients. RESULTS: From January 1996 to January 1997, 30 patients with endometrial adenocarcinoma and 19 with cervical adenocarcinoma entered the study, for a total of 213 cycles of treatment. In patients with endometrial carcinoma the overall clinical and pathological response rates were 73% (95% CI, range 54%-88%) and 35% (95% CI, range 16%-57%) respectively; in patients with locally advanced cervical carcinoma the overall clinical and pathological response rates were 64% and 62%. WHO grade 3-4 neutropenia occurred in 61% of the patients, with one possible toxic death. Retreatment had to be delayed for at least one week because of persisting neutropenia in 34% of the patients. Mild peripheral neuropathy and stomatitis were observed in 46% and 23% of the patients. One patient presented acute congestive heart failure after the third cycle of treatment. CONCLUSION: The high antitumour activity and the good tolerability of CEP suggest that this regimen should be prospectively compared to standard combinations as initial treatment of advanced endometrial carcinoma.
