Weekly administration of topotecan-paclitaxel as second-line treatment in ovarian cancer.

PURPOSE: To investigate the weekly administration of topotecan combined with paclitaxel in pretreated advanced ovarian cancer patients; our objectives were to determine efficacy, toxicity and survival. METHODS: The chemotherapy agents, topotecan and paclitaxel were administered on a weekly basis for 3 consecutive weeks, every 28 days. The plan was to give three courses (each course included three once-weekly infusions). The dose of topotecan was 1.75 mg/m(2) and of paclitaxel 70 mg/m(2). RESULTS: From January 2004 until January 2006, 45 patients were enrolled in this multicenter trial; 44 patients were evaluable for response and toxicity. The median age was 60 years old (range 39-82 years) and performance status was 0-2. Thirty-nine patients were in stage III and 5 in stage IV. All patients had been pretreated with carboplatin or cisplatin in combination with paclitaxel. Complete and partial responses were seen in 39% of the patients, stable disease in 43% and progressive disease in 18%; median survival time was 9 months, range 2-24+ months, (95% CI: 7.9-10.2). There was a notable absence of grade 3 toxicity except for neutropenia in 11% of the patients. CONCLUSION: The combination of topotecan and paclitaxel administered on a weekly basis is a well-tolerated chemotherapy schedule. The response rate of 39% is quite high for patients with pretreated ovarian cancer.

Postoperative dose-dense sequential chemotherapy with epirubicin, followed by CMF with or without paclitaxel, in patients with high-risk operable breast cancer: a randomized phase III study conducted by the Hellenic Cooperative Oncology Group.

PURPOSE: The aim of this study was to explore the effect of dose-dense sequential chemotherapy with or without paclitaxel primarily on disease-free survival (DFS) and secondarily on overall survival (OS) in patients with high-risk operable breast cancer. PATIENTS AND METHODS: From June 1997 until November 2000, 604 patients with T1-3N1M0 or T3N0M0 tumors were randomized to three cycles of epirubicin 110 mg/m2 followed by three cycles of paclitaxel 250 mg/m2 followed by three cycles of 'intensified' CMF (cyclophosphamide 840 mg/m2, methotrexate 47 mg/m2 and fluorouracil 840 mg/m2) (group A), or to four cycles of epirubicin followed by four cycles of CMF, as in group A (group B). All cycles were given every 2 weeks with granulocyte colony-stimulating factor support. RESULTS: A total of 595 patients were eligible. Median follow-up was 61.7 months for group A and 62 months for group B. The 3-year DFS was 80% in group A and 77% in group B. Survival rates were 93% and 90%, respectively. The effect of treatment on the hazard of death was different according to hormonal receptor status. More specifically, in patients with negative receptor status the hazard of death was significantly higher for group B (hazard ratio 2.42). Both regimens were well tolerated and severe acute side-effects were infrequent. No cases of severe cardiotoxicity or acute leukemia were recorded. CONCLUSIONS: The present study failed to demonstrate a significant difference in DFS or OS between the two treatment groups. However, our study has shown clearly that high-dose paclitaxel can be safely incorporated to dose-dense sequential chemotherapy.

Second-line chemotherapy in small cell lung cancer in a modified administration of topotecan combined with paclitaxel: a phase II study.

PURPOSE: Our main objective was to investigate the response rate in pretreated patients with small cell lung cancer (SCLC) who received a weekly administration of topotecan and paclitaxel; our secondary objectives were to assess toxicity and survival. METHODS: Topotecan 1.75 mg/m2 was combined with paclitaxel 70 mg/m2; these cytotoxic agents were administered once every week (day 1) for 3 consecutive weeks (one cycle), and repeated every 28 days (three infusions per cycle) for a minimum of three cycles. RESULTS: Forty-five patients were enrolled, 41 of whom were evaluable for response and toxicity. The median number of cycles was two (range 1-6). Eleven/forty-one (26.83%) patients responded: one complete response and ten partial responses; the median duration of response was 4 months (range 2-8 months); the median overall survival was 7 months (95% CI: 4.2-9.8). Myelotoxicity was the most common adverse reaction (grade 3 neutropenia in 19.5% of the patients and grade 4 in 7.32%). Non-hematologic toxicities varied from 2.44% to 9.76%. No patient had to stop treatment due to toxicity. CONCLUSION: Topotecan combined with paclitaxel, given on day 1 on a weekly basis, produced a response rate of 26.83% in pretreated patients with SCLC. Myelotoxicity, particularly neutropenia, was the main adverse reaction, but in a minority of patients.

Phase I study of etoposide, cisplatin and irinotecan triplet in patients with advanced-stage small-cell lung cancer.

AIM: The irinotecan-cisplatin combination has emerged as a new standard for the treatment of advanced-stage small-cell lung cancer (AS-SCLC). To move forward we developed a 3-day regimen of cisplatin, etoposide and irinotecan. METHODS: Successive cohorts of AS-SCLC patients were treated with irinotecan administered as a single 1-h infusion in combination with fixed doses of cisplatin (20 mg/m(2)) and etoposide (75 mg/m(2)), both given for three consecutive days (ECI regimen). Irinotecan dose was escalated from 60 mg/m(2) by 40-mg/m(2) increments. At mid-step between the maximum tolerated dose (MTD) and the previous dose level, patients were randomized for the day of administration of irinotecan (day 1 vs day 3). RESULTS: A total of 36 AS-SCLC patients received 166 courses of treatment at four dose levels. The MTD of irinotecan was 140 mg/m(2) (three dose-limiting toxicities, DLTs), and the recommended optimal dose (ROD) 120 mg/m(2) (two DLTs). DLTs were febrile neutropenia and grade 3 diarrhea. Other toxicities were mild. No difference in toxicity was seen between the two time schedules. A 77% (95% CI 63.25-90.75%) response rate was recorded among 31 evaluable patients and the median survival was 12 months. CONCLUSIONS: The ECI regimen was well tolerated and showed considerable activity in patients with AS-SCLC. Phase II/III evaluation is ongoing.

Irinotecan or oxaliplatin combined with leucovorin and 5-fluorouracil as first-line treatment in advanced colorectal cancer: a multicenter, randomized, phase II study.

BACKGROUND: Irinotecan (IRI) and oxaliplatin (OXA) are effective in the treatment of colorectal cancer. Previously untreated patients with advanced colorectal carcinoma (CRC) were randomly assigned to receive IRI plus leucovorin (LV)/5-fluorouracil (5-FU), or OXA plus LV/5-FU in order to compare the response rates, time-to-tumor progression, overall survival rates, and toxicity profiles of these two agents. MATERIALS AND METHODS: From January 1999 to February 2002, 295 patients were randomized to receive either IRI/LV/5-FU or OXA/LV/5-FU. The treatment schedules consisted of weekly IRI 70 mg/m(2) or OXA 45 mg/m(2) plus LV 200 mg/m(2) followed immediately by intravenous bolus 5-FU 450 mg/m(2) for 6 weeks, followed by a 2-week rest period. Treatment was continued for up to four cycles or until disease progression, unacceptable toxicity or patient refusal. RESULTS: There were no significant differences between the study arms in the overall response rate (33% with IRI/LV/5-FU versus 32% with OXA/LV/5-FU based on responses demonstrated on a single evaluation; 23% with IRI/LV/5-FU versus 22.3% with OXA/LV/5-FU based on responses confirmed according to WHO criteria) median time to progression (8.9 versus 7.6 months), and median overall survival (17.6 versus 17.4 months). Toxicity profiles (grades 3 and 4) were similar in the IRI and OXA arms (diarrhea 12.3% and 9.8%, neutropenia 8.2% and 4.9%, and febrile neutropenia 1.4% and 1.4%, respectively), with the exception of grade 3 sensory neuropathy, which almost exclusively occurred in the OXA arm (0% versus 5.6%; P=0.003, Fisher's exact test). CONCLUSION: The IRI/LV/5-FU and OXA/LV/5-FU regimens demonstrated equally substantial efficacies and manageable toxicity profiles in the first-line treatment of patients with advanced CRC. However, IRI/LV/5-FU may be the preferable regimen to avoid significant neurotoxicity associated with OXA-LV/5-FU.

Carboplatin plus gemcitabine in patients with inoperable or metastatic pancreatic cancer: a phase II multicenter study by the Hellenic Cooperative Oncology Group.

BACKGROUND: In the present phase II multicenter study, we assessed the efficacy and tolerability of the combination of gemcitabine and carboplatin in patients with advanced pancreatic cancer. PATIENTS AND METHODS: Patients with previously untreated, locally advanced or metastatic pancreatic cancer were treated with gemcitabine 800 mg/m(2) on days 1 and 8 and carboplatin at an AUC of 4 on day 8 of a 3-week cycle, for a total of six cycles. Primary end points were response rate and clinical benefit; secondary end points were, survival, time to progression (TTP) and toxicity. RESULTS: A total of 50 patients were enrolled in the study, 47 of whom were eligible for treatment. The median age was 63 years (range 34-76) and the median Karnofsky performance status (PS) was 80%. Patients received a median of six cycles (range 1-11). Among 35 patients evaluable for response, eight (17%) achieved partial response; 15 (32%) and 12 (25%) patients had stable and progressive disease, respectively. The median overall survival was 7.4 months; the median TTP was 4.4 months and the 1-year survival was 28%. The observed clinical benefit response was remarkable. After the second cycle of chemotherapy, 21 of 31 (68%) patients experienced pain improvement and reduced analgesic consumption. At the same time, 35% and 56% of our patients significantly improved their Karnofsky PS and weight, respectively. Overall, the treatment was well tolerated. The most common grade 3-4 toxicities were hematological, including 8% anemia, 6% neutropenia and 13% thrombocytopenia. CONCLUSIONS: The combination of gemcitabine plus carboplatin is a moderately active treatment for patients with locally advanced and metastatic pancreatic cancer. This regimen has an acceptable toxicity profile and provides a significant clinical benefit, and hence warrants further investigation.

Combination of docetaxel, estramustine phosphate, and zoledronic acid in androgen-independent metastatic prostate cancer: efficacy, safety, and clinical benefit assessment.

OBJECTIVES: Docetaxel is an effective agent for the treatment of androgen-independent prostate cancer (AIPC). Its combination with estramustine phosphate (EMP) has shown promising results in AIPC but the toxicity remains considerable. In an effort to minimize toxicity, we designed an every-2-week docetaxel administration regimen with a 3-day low-dose EMP regimen. Patients with bone metastases also received zoledronic acid. METHODS: A total of 54 patients with AIPC received docetaxel at 45 mg/m2 and EMP (140 mg orally every 8 hours for nine doses) every 2 weeks. Zoledronic acid was administered at 4 mg every 28 days. RESULTS: Of the 49 assessable patients, 22 (45%, 95% confidence interval [CI] 31% to 60%) had a prostate-specific antigen response. Of 24 patients with measurable disease, 9 (38%, 95% CI 19% to 59%) had a response to therapy (one complete response and eight partial responses). The median time to progression was 4.4 months (95% CI 2.7 to 6), and overall survival was 13.3 months (95% CI 9 to 17.6). Toxicity was mild, with only 5 cases of grade 3 or 4 toxicity. The pain score improved by 1 point in 21 (54%) of 39 symptomatic patients, and 14 (40%) of 38 patients who used analgesics discontinued analgesic consumption by the end of treatment. CONCLUSIONS: The combination of an every-2-week regimen of docetaxel, EMP, and zoledronic acid is an effective, well-tolerated regimen that results in symptomatic improvement in a significant proportion of patients with AIPC.

Treatment of non-small cell lung cancer with gefitinib ('Iressa', ZD1839): the Greek experience with a compassionate-use program.

This is a retrospective analysis of 150 patients with advanced non-small cell lung cancer who had failed prior treatment or were unfit for chemotherapy and were treated with oral gefitinib ('Iressa', ZD1839; AstraZeneca) 250 mg/day. Thirty-two patients who received gefitinib for 3 weeks or less were not included in the analysis. For the remaining 118 evaluable patients, the mean age was 63.1 years; most patients had received prior chemotherapy (97.5%), Eastern Cooperative Oncology Group performance status scores 0-2 (97.4%) and stage IV disease (64.4%). The majority were symptomatic (84.6%). Disease control was observed in 30 patients (25.4%), of whom five had a partial response and 25 had stable disease; 18 (15.3%) were not evaluable. Median duration of treatment was 29.9 weeks in responding patients and 11.5 in patients with progressive disease (p<0.0001). Median overall survival was 7.3 months (15.2 months for disease control) and median progression-free survival was 3.2 months. Gefitinib was well tolerated, with grade 3/4 skin rash and diarrhea seen in 2.5 and 4.2% of patients, respectively. Clinical benefit was evaluated using questionnaires before and following treatment with gefitinib. In 82 patients with completed questionnaires, evaluation revealed symptom improvement in 40.1% and improvement in general feeling in 31.4%. Epidermal growth factor receptor (EGFR) analysis found that efficacy did not correlate with tumor EGFR overexpression. Therefore, in this retrospective analysis, gefitinib treatment provided disease control in 25% of patients who derived significant palliative benefit.

Combination of pegylated liposomal doxorubicin (PLD) and paclitaxel in patients with advanced soft tissue sarcoma: a phase II study of the Hellenic Cooperative Oncology Group.

Patients with soft tissue sarcoma (STS), even after complete local disease control, often relapse locally or with distant metastases. This multicenter phase II study was conducted to evaluate the safety and efficacy of the combination of pegylated liposomal doxorubicin (PLD) and paclitaxel, as first-line treatment in patients with advanced STS. In all, 42 patients with locally advanced or metastatic STS, median age 54 years and median Eastern Cooperative Oncology Group performance status (PS) 1 were treated with PLD 45 mg m(-2) and paclitaxel 150 mg m(-2), every 28 days for a total of six cycles. Histological types included mainly leiomyosarcomas (43%), malignant fibrous histiocytomas (14%) and liposarcomas (12%). At study entry, 69% of patients had distant metastases. Overall response rate was 16%, including one complete (CR 2%) and six partial responses (PRs 14%), while an additional 14 patients had disease stabilization (SD 33%). At median follow-up 41.5 months, median time to progression (TTP) was 5.7 months with median overall survival (OS) 13.2 months. Grade 3-4 toxicities included neutropenia (17%), anaemia (15%), neurotoxicity (5%) and palmar-plantar erythrodysesthesia (9%). There were no treatment-related deaths. The combination of PLD and paclitaxel is a safe and well-tolerated regimen demonstrating modest efficacy as first-line treatment in patients with advanced STS.

Gemcitabine and oxaliplatin (GEMOX) in patients with cisplatin-refractory germ cell tumors: a phase II study.

BACKGROUND: To investigate the efficacy and toxicity of the combination of gemcitabine and oxaliplatin (GEMOX) in patients with relapsed or cisplatin-refractory non-seminomatous germ cell tumors (NSGCT). PATIENTS AND METHODS: Twenty-nine patients with relapsed or cisplatin-refractory NSGCT were treated with gemcitabine 1000 mg/m2 on days 1 and 8 followed by oxaliplatin 130 mg/m2 on day 1 every 3 weeks for a maximum of six cycles. Twenty-four patients (83%) were considered refractory and five (17%) absolutely refractory to cisplatin. RESULTS: Twenty-eight patients were assessable for response. Overall, nine patients (32%) achieved a favourable response (complete response, four; partial response, five). One of the complete responders relapsed after 7 months and went into disease-free status lasting for 11+ months after resection of lung metastases. The rest of the complete responders are continuously disease-free at 14+, 19+ and 28+ months with the study regimen plus or minus surgery. One of the complete responders had absolutely cisplatin-refractory disease and another one presented with a late relapse. Toxicity was primarily hematological and generally manageable: 62% of patients experienced grade 3/4 neutropenia, 10% neutropenic fever and 41% grade 3/4 thrombocytopenia. Non-hematological toxicity consisted mainly of nausea/vomiting. Three patients (10%) developed grade 3 neurotoxicity and discontinued treatment. CONCLUSIONS: The combination of GEMOX is an active, moderately toxic and easily administered regimen in patients with relapsed or cisplatin-refractory NSGCT. The 14% long-term disease-free status accomplished in this heavily pretreated patient population is quite encouraging.

Paclitaxel and epirubicin versus paclitaxel and carboplatin as first-line chemotherapy in patients with advanced breast cancer: a phase III study conducted by the Hellenic Cooperative Oncology Group.

BACKGROUND: To compare survival between patients with advanced breast cancer (ABC) treated with epirubicin/paclitaxel (Taxol) or paclitaxel/carboplatin (Cp) chemotherapy. PATIENTS AND METHODS: From January 1999 to April 2002, 327 eligible patients with ABC were randomized to receive either paclitaxel 175 mg/m(2) in a 3-h infusion followed by epirubicin (EPI) 80 mg/m(2) (group A) or paclitaxel, as in group A, followed by Cp at an AUC of 6 mg x min/ml (group B) every 3 weeks for six cycles. RESULTS: After a median follow-up of 23.5 months, median survival was not significantly different between the two groups (22.4 months versus 27.8 months, P=0.25), whereas median time to treatment failure was significantly longer in patients treated with paclitaxel/Cp (8.1 months in group A versus 10.8 months in group B, P=0.04). Both regimens were well tolerated. In total, 39 patients (24%) in group A and 46 (29%) in group B suffered at least one severe side-effect. Quality-of-life assessment and cost analysis did not reveal any significant differences between the two groups. CONCLUSION: Our study suggests that the paclitaxel/Cp combination is an effective therapeutic alternative for patients with ABC in which anthracycline administration has the potential of being harmful.

Adjuvant cytotoxic and endocrine therapy in pre- and postmenopausal patients with breast cancer and one to nine infiltrated nodes: five-year results of the Hellenic Cooperative Oncology Group randomized HE 10/92 study.

SUMMARY: The present randomized phase III trial was designed to detect a 15% benefit in relapse-free survival (RFS) or overall survival (OS) from the incorporation of adjuvant tamoxifen to the combination of CNF [cyclophosphamide, 500 mg/m2; mitoxantrone (Novantrone), 10 mg/m2; fluorouracil, 500 mg/m2 chemotherapy and ovarian ablation in premenopausal patients with node-positive breast cancer and conversely from the incorporation of CNF chemotherapy to adjuvant tamoxifen in node-positive postmenopausal patients. From April 1992 until March 1998, 456 patients with operable breast cancer and one to nine infiltrated axillary nodes entered the study. Premenopausal patients were treated with six cycles of CNF chemotherapy followed by ovarian ablation with monthly injections of triptoreline 3.75 mg for 1 year (Group A, 84 patients) or the same treatment followed by 5 years of tamoxifen (Group B, 92 patients). Postmenopausal patients received 5 years of tamoxifen (Group C, 145 patients) or 6 cycles of CNF followed by 5 years of tamoxifen (Group D, 135 patients). Adjuvant radiation was administered to all patients with partial mastectomy. After a median follow-up period of 5 years, 125 patients (27%) relapsed and 79 (17%) died. The 5-year actuarial RFS for premenopausal patients was 65% in Group A and 68% in Group B (p = 0.86) and for postmenopausal patients 70% in Group C and 67% in Group D (p = 0.36). Also, the respective OS rates were 77% and 80% (p = 0.68) for premenopausal and 84% and 78% (p = 0.10) for postmenopausal patients. Severe toxicities were infrequently seen, with the exception of leukopenia (18%), among the 311 patients treated with CNF. In conclusion, the present study failed to demonstrate a 15% difference in RFS in favor of node-positive premenopausal patients treated with an additional 5 years of tamoxifen after CNF adjuvant chemotherapy and ovarian ablation. Similarly, six cycles of CNF preceding 5 years of tamoxifen did not translate to a 15% RFS benefit in node-positive postmenopausal patients.

The combination of estramustine and mitoxantrone in hormone-refractory prostate cancer: a phase II feasibility study conducted by the Hellenic Cooperative Oncology Group.

OBJECTIVES: To consider the safety profile and therapeutic value of the combination of estramustine and mitoxantrone in a bimonthly schedule to treat hormone-refractory prostate cancer. The survival of patients with prostate cancer who relapse after androgen ablation is limited and the therapeutic options are restricted. METHODS: Twenty-nine patients with relapse after previous treatment were included in the study; however, 3 patients who refused to start treatment were not included in the analysis, leaving 26 eligible patients. The median age was 64 years (range 44 to 82), the World Health Organization performance status ranged from 1 to 3, and the mean prostate-specific antigen level was 103 ng/mL (range 1 to 620). The Gleason score ranged from 2 to 9. The patients received a total of 208 therapeutic cycles (mean 8, range 3 to 24). Every cycle consisted of oral estramustine 140 mg, 3 times a day continuously, and intravenous mitoxantrone 20 mg (total dose). The regimen was repeated every 2 weeks. RESULTS: Twenty-seven percent of patients with measurable soft-tissue disease demonstrated an objective response, which included one complete and six partial responses. Thirteen patients (50%) had a greater than 50% reduction in serum prostate-specific antigen level. The median duration of response was 9.2 months, and the median survival for all patients was 15 months. The most common side effects were neutropenia and thrombocytopenia. CONCLUSIONS: The combination of estramustine and mitoxantrone is safe, well tolerated, and relatively active in patients with hormone-refractory prostate cancer. More patients are needed to partake in Phase III studies to establish the survival benefit that this combination may offer.

A phase II study with CPT-11 plus leucovorin and bolus IV 5-fluorouracil in patients with advanced colorectal carcinoma.

Standard chemotherapy in advanced colorectal carcinoma (CRC) has not yet been established. The present study was conducted to assess the efficacy and toxicity profile of CPT-11, leucovorin (LV), and bolus 5-fluorouracil (5-FU) in a weekly schedule. Fifty-five patients were entered with no prior chemotherapy for advanced disease or adjuvant treatment ended at least 6 months preceding study entry, and 45 were assessable for response. Patients were treated with CPT-11 80 mg/m2 (7 patients) or 70 mg/m2 (48 patients). After completion of CPT-11 infusion, LV 200 mg/m2 was administered over 2 hr followed immediately by 5-FU 450 mg/m2, IV bolus, weekly for 6 weeks followed by a 2-week rest period. Treatment was continued for four cycles. Because of grade 3 and 4 diarrhea in four of the first seven patients, the study was amended to reduce the starting dose of CPT-11 from 80 to 70 mg/m2 weekly. Four complete and 10 partial responses were observed (response rate: 25.5%), the median time to progression (TTP) was 7.7 months, 1-year survival rate was 62.3%, and the median overall survival was 15.0 months. Grade 3 and 4 diarrhea occurred in seven patients (12.7%), four of them treated with CPT-11 80 mg/m2. Grade 3 myelotoxicity occurred in five patients (9.0%). Toxic death because of diarrhea, neutropenia, bacteremia, and sepsis occurred in a patient treated with CPT-11 80 mg/m2. Our results confirm the efficacy of CPT-11, LV, and 5-FU in a weekly schedule in patients with advanced CRC. Further studies are needed to compare the present regimen with higher doses of CPT-11 with LV plus different schedules of 5-FU administration in the treatment of metastatic CRC.

Germ line BRCA1 & BRCA2 mutations in Greek breast/ovarian cancer families: 5382insC is the most frequent mutation observed.

BRCA1 and BRCA2 genes were screened for loss-of-function mutations in a series of 85 patients having at least one first- or second-degree relative affected by breast and/or ovarian cancer. All BRCA1 exons and BRCA2 exons 10 and 11 were screened with a combination of methods including SSCP, PTT and direct sequencing. We have found disease-associated mutations in 14 families (16.5%), eleven in BRCA1 and three in BRCA2. The known founder mutation 5382insC of BRCA1 was identified in seven unrelated families. The other mutations identified include the non-sense R1751X, the splice junction variant 5586G>A of BRCA1 and three frameshifts, 2024del5, 3034del4, and 6631del5, of BRCA2. Nine out of these 14 families had a family history of three or more breast/ovarian cancer cases. A large number of polymorphic or unclassified variants is also reported. Combined with our previously published data 5382insC was found in nine out of 20 families (45%), suggesting that this mutation may represent a common founder mutation in the Greek population.

Temozolomide in combination with docetaxel in patients with advanced melanoma: a phase II study of the Hellenic Cooperative Oncology Group.

PURPOSE: Temozolomide is a novel oral alkylating agent that is effective against melanoma. Moreover, temozolomide readily crosses the blood-brain barrier and may consequently be effective in patients with brain metastases. This phase II study was performed to assess the efficacy and safety of the combination regimen of temozolomide and docetaxel in patients with advanced metastatic melanoma. PATIENTS AND METHODS: Sixty-five patients with metastatic melanoma were enrolled. Treatment consisted of intravenous docetaxel (80 mg/m(2)) on day 1 and oral temozolomide (150 mg/m(2)) on days 1 to 5, every 4 weeks, for a maximum of six cycles. RESULTS: Sixty-two patients were eligible for the efficacy and safety analysis. Seventeen patients (27%) achieved an objective response, including five complete (8%) and 12 partial responses (19%). Median response duration was 9.5 months. Among responders, median time to progression (TTP) was 11.2 months and median overall survival (OS) was 16 months. For all treated patients, the median TTP was 4 months and median OS was 11 months. Three (38%) of eight patients who presented with brain metastases had a partial response for 5, 6, and 12 months. Of 52 patients who did not have brain involvement at presentation, only four (8%) developed brain metastases at a median follow-up of 14 months. Myelosuppression was the primary toxicity. CONCLUSION: The combination of temozolomide and docetaxel was effective and well tolerated as first-line treatment for patients with advanced metastatic melanoma and demonstrated encouraging antitumor activity against brain metastases.

Vinblastine and interferon-gamma combination with and without 13-cis retinoic acid for patients with advanced renal cell carcinoma. Results of two phase II clinical trials.

BACKGROUND: The aim of this study is firstly to determine the response rates and toxicity of two regimens containing vinblastine (VBL) in combination with interferon-gamma (IFN-gamma) in the treatment of patients with advanced renal cell carcinoma (RCC), and secondly to evaluate the additional efficacy of 13-cis retinoic acid (13-CRA) in RCC. METHODS: Twenty-nine patients were included in the first trial (Trial 1) and 40 in the second one (Trial 2). The therapy given in Trial 1 consisted of VBL 0.15 mg/kg i.v. every 2 weeks and IFN-gamma 100 microg s.c. 3 times weekly. In Trial 2, the therapy consisted of the same two drugs, in the same doses, plus oral 13-CRA 40 mg/day. RESULTS: In Trial 1 there were 3 (10.3%) patients with complete response, 3 (10.3%) patients with partial response, 8 (27.6%) patients with stable disease and 15 (51.7%) patients with progressive disease. In Trial 2, there was no complete response, however, 3 (7.5%) patients had partial response. Additionally, 15 (37.5%) patients maintained stable disease and 14 (35%) patients had progressive disease. In Trial 1, the median survival was 12.56 months (95% CI, 6.8-18.3, range 0.59-42.49) and the median time to progression was 3.21 months (95% CI, 1.7-4.7, range 0.03-42.49). In Trial 2, the median survival was 9.54 months (95% CI, 5.9-13.1, range 0.43-24.1) and the median time to progression was 3.9 months (95% CI, 0.8-7, range 0.26-24.1). In Trial 1, granulocytopenia grade 3 and 4 appeared in 5 (17.2%) patients and anaemia grade 3 in 1 (3.4%) patient. In Trial 2, there were grade 3 toxicities, as granulocytopenia in 5 (12.5%) patients, anemia in 4 (10.0%) patients, stomatitis in 3 (7.5%) patients, fatigue/malaise in 3 (7.5%) patients and 1 (2.5%) had diarrhea. No toxic deaths occurred in both studies. CONCLUSION: The use of IFN-gamma does not enhance the low response of VBL-based chemotherapy. The additional administration of 13-CRA with the combination of VBL and IFN-gamma does not add to the efficacy of this combination in patients with advanced renal cell carcinoma. New active agents are needed to treat patients with this disease.

Dose-dense sequential chemotherapy with epirubicin and paclitaxel versus the combination, as first-line chemotherapy, in advanced breast cancer: a randomized study conducted by the Hellenic Cooperative Oncology Group.

PURPOSE: To compare the efficacy of two different schedules of epirubicin and paclitaxel, as first-line chemotherapy, in patients with advanced breast cancer (ABC). PATIENTS AND METHODS: From October 1997 until May 1999, 183 eligible patients with ABC entered the study. Chemotherapy in group A (93 patients) consisted of four cycles of epirubicin at a dose of 110 mg/m(2) followed by four cycles of paclitaxel at a dose of 225 mg/m(2) in a 3-hour infusion. All cycles were repeated every 2 weeks with granulocyte colony-stimulating factor support. The therapeutic regimen in group B (90 patients) consisted of epirubicin (80 mg/m(2)) immediately followed by paclitaxel (175 mg/m(2) in a 3-hour infusion) every 3 weeks for six cycles. RESULTS: In total, 79 patients (85%) in group A and 72 patients (80%) in group B completed treatment. The median relative dose-intensity of epirubicin was 0.96 in both groups, and that of paclitaxel was 0.96 and 0.97 in groups A and B, respectively. The complete response rate was higher in group A (21.5% v 9% P =.02). Nevertheless, there was no significant difference in the overall response rate between the two groups (55% v 42%, P =.10). Severe neutropenia was more frequently observed with concurrent treatment. After a median follow-up of 16.5 months, median time to progression was 10 months in group A and 8.5 months in group B (P =.27), and median survival was 21.5 and 20 months, respectively (P =.17). CONCLUSION: The present study failed to demonstrate a significant difference in overall response rate between dose-dense sequential administration of epirubicin and paclitaxel compared with the combination of the two drugs given on the same day, even though the sequential treatment resulted in a significantly higher complete response rate.
