Prognostic significance of the sequential detection of circulating melanoma cells by RT-PCR in high-risk melanoma patients receiving adjuvant interferon.

The purpose of this study was to address the prognostic significance of circulating melanoma cells by reverse transcriptase-polymerase chain reaction in the peripheral blood of stage IIB and III melanoma patients on high-dose adjuvant interferon at multiple sequential time points from initiation of treatment. Tyrosinase mRNA in peripheral blood from these patients was assayed by reverse transcriptase polymerase chain reaction prior to initiation of adjuvant interferon, at completion of 1 month of intravenous interferon and at 3 monthly intervals until progression. Four hundred and eighteen blood samples from 60 melanoma patients were analysed. The median follow-up time calculated from the time of inclusion in the study was 23 months (range 2-38 months). Tyrosinase mRNA in blood was detected in 42 (70%) of 60 patients: 16 (76%) of 21 stage IIB patients and 26 (66% ) of 39 stage III patients. The presence of tyrosinase mRNA in blood was correlated with a shorter disease-free survival (P : 0.03) and in multivariante analysis was an independent prognostic factor for relapse. Patients who seroconverted to a negative reverse-transcriptase-polymerase chain reaction after induction treatment had a significantly lower probability of recurrence. The presence of circulating melanoma cells is a marker of a high relapse risk and shorter disease-free survival whether detected postoperatively or during follow-up. Tyrosinase mRNA amplification by reverse-transcriptase-polymerase chain reaction may be a useful tool for monitoring the efficacy of adjuvant treatment in stage IIB and III melanoma patients.

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.

Neoadjuvant chemotherapy with a combination of pegylated liposomal doxorubicin (Caelyx) and paclitaxel in locally advanced breast cancer: a phase II study by the Hellenic Cooperative Oncology Group.

BACKGROUND: To determine the activity and safety of the combination of paclitaxel and pegylated liposomal doxorubicin (Caelyx) in patients with locally advanced breast cancer. PATIENTS AND METHODS: This was a multicenter phase II study. Thirty-five newly diagnosed patients with locally advanced breast cancer were included in the study. Histological or cytological diagnosis was necessary for inclusion. Median age was 54 years (range 26-73 years). Fifteen patients were premenopausal and 20 postmenopausal. Paclitaxel was administered at a dose of 175 mg/m(2) and pegylated liposomal doxorubicin 35 mg/m(2) every 3 weeks for six cycles. RESULTS: Twenty-five patients (71%) responded. Six (17%) had a complete response, 19 (54%) had a partial response, four remained stable, two progressed and four were not evaluated for response due to discontinuation of chemotherapy. Three patients had a pathologically complete response. A total of 173 cycles were administered. The primary toxicity observed was skin toxicity. Grade 3 skin toxicity was noted in four patients (11%). Palmar-plantar erythrodysesthesia (PPE) grade 3 was experienced by three (9%). Two patients presented with PPE and skin toxicity. Hematological toxicities included grade 3 leukopenia in four patients (3%). Other grade 3 toxicities were uncommon and included only alopecia in 29 patients (83%). Grade 3 or 4 neurotoxicity was not observed in any patient. Dose reduction was necessary in seven patients; in six due to skin toxicity and in one due to neutropenia. Four patients discontinued treatment due to skin toxicity. There were no treatment-related deaths. CONCLUSIONS: The combination of pegylated liposomal doxorubicin and paclitaxel was active in locally advanced breast cancer. The primary toxicity was cutaneous toxicity and it was manageable.

Malignant melanoma metastatic to the gastrointestinal tract.

A retrospective study of 385 melanoma patients was performed, with the goal of evaluating the clinical characteristics, the role of imaging and the impact of treatment on patients with gastrointestinal (GI) metastases. Eighteen patients (4.7%) had GI tract metastases. In 50% the primary lesion was on the lower extremities (P< 0.01), while 61.1% had nodular melanomas (P < 0.01). Imaging and/or endoscopy were undertaken in 72.2% of the patients, yielding positive results in all. Eight patients underwent curative surgery, two received no treatment, while the remaining eight patients had chemotherapy or immunochemotherapy. Long-term palliation was offered to 87.5% of the surgical patients compared with 50% of the patients treated medically. Median survival in the patients treated with surgery was 47.5 months compared with 5.8 months in the medical group (P < 0.01). GI tract metastases were more common in patients with nodular melanoma of the lower extremities. To our knowledge, this is the first study correlating the primary lesion's characteristics with the development of GI tract metastases. Imaging is effective in the diagnosis of GI tract involvement. Melanoma patients with GI tract metastases can benefit from palliation by surgical resection. Survival is improved when such patients are treated with curative surgery.

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.

Docetaxel in combination with dacarbazine in patients with advanced melanoma.

OBJECTIVES: The number of agents that are active in patients with metastatic melanoma is limited and cure is not a realistic objective for treatment at this stage. The aim of the study was to evaluate the efficacy and safety of new combination regimen cosisting of docetaxel and dacarbazine (DTIC), as first-line chemotherapy, in patients with advanced melanoma. PATIENTS AND METHODS: Patients with advanced melanoma (including cerebral metastases) were eligible. Docetaxel 80 mg/m(2), i.v. over 1 h infusion on day 1, and DTIC 400 mg/m(2), i.v. over 45 min on days 1 and 2, were given every 21 days, for six cycles. All patients were premedicated, prior to each course, with methylprednisolone per os. RESULTS: Forty-one patients entered the study. Thirty-nine were assessable for response and 40 for toxicity. Objective responses were seen in 10 patients (24% of the eligible; 95% CI = 12.4-40.3%, 26% of the assessable and 28% of patients with cerebral metastases were excluded). Three of them achieved a complete response (7%; 95% CI = 1.5-19.9) and 7 a partial response (17%; 95% CI = 7.1-32.0), while 8 patients demonstrated stabilization of their disease (20%; 95% CI = 8.8-34.9). After a median follow-up of 20 months, the median time to progression was 7 months (range 0.5-22) and the median survival was 10 months (1-24+). The main toxicity (G3-4) was neutropenia which occurred in 8/40 (20%) patients. Additional patients had reversible G3-4 toxicities including alopecia, nausea and vomiting and fatigue; 3 of them presented mild to moderate hypersensitivity reactions to docetaxel. No toxic death was noted. CONCLUSIONS: The combination of docetaxel and DTIC is active and well tolerated in patients with advanced melanoma. While this combination is at least as effective as various combination regimens, it does not differ from that reported for single-agent DTIC.

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.

Phase II study of temozolomide in heavily pretreated cancer patients with brain metastases.

PURPOSE: To determine the efficacy, tolerability, and safety of temozolomide in heavily pretreated patients with solid tumors and brain metastases. PATIENTS AND METHODS: Twenty-seven of twenty-eight enrolled patients with brain metastases from solid tumors received temozolomide (150 mg/m2/day for five days every 28 days). Twelve patients had non-small-cell lung cancer, five patients had small-cell lung cancer, four patients had breast cancer, and seven patients had other solid tumors. The majority of the patients had multiple metastatic sites, a poor performance status, and had been heavily pretreated. The primary end points were objective response rate, time to progression, and overall survival. Secondary end points included safety and tolerability, and neurologic performance status. RESULTS: A partial response was achieved in 1 (4%) of 24 evaluable patients. Disease stabilization was observed in four (17%) patients. Overall median survival was 4.5 months and median time to progression was 3 months. Improvements in clinical neurologic status were achieved in 10 (37%) patients. Treatment with temozolomide was well tolerated. Four patients had grade 3 nausea and vomiting. No grade 4 toxicity or treatment-related deaths were observed. CONCLUSIONS: Temozolomide demonstrated encouraging activity in the treatment of brain metastases in heavily pretreated patients with solid tumors, and was safe and well tolerated.

Combination chemotherapy with gemcitabine and ifosfamide as second-line treatment in metastatic urothelial cancer. A phase II trial conducted by the Hellenic Cooperative Oncology Group.

PURPOSE: The aim of the study was to evaluate the efficacy and safety of the combination of gemcitabine and ifosfamide as a second-line treatment for advanced urothelial cancer. PATIENTS AND METHODS: Thirty-four patients with metastatic urothelial cancer previously treated with cisplatin (CDDP)/ carboplatin (CBDCA) and/or taxanes-based chemotherapy were studied. Gemcitabine was administered at a dose of 800 mg/m2 on days 1 and 8 and ifosfamide at a dose of 2 g/m2 on days 1 and 8 with adequate amount of Mesna. every three weeks. Hematopoietic growth factors were given between days 3 to 5 and 12 to 16 to maintain the treatment schedule. RESULTS: On an intent to treat basis, there was one complete response (CR) (3%) (95% confidence interval (95% CI): 0% to 10%) and six partial responses (PR) (18%) (95% CI: 7% to 34%). inducing an objective response rate (RR) of 21% (95% CI: 9% to 38%); 12 (35%) patients achieved a stable disease (SD) and 15 (44%) a progressive disease (PD). The median time to tumor progression (TTP) was four months (range, 0.52 to 21.6 months) and the median survival nine months (range 0.52 to 28 months). This regimen also provided the opportunity for symptomatic improvement of pain, dysuria, haematuria and leg oedema. Grade 3-4 neutropenia was experienced by 9 (27%) patients, grade 3 4 anemia by 6 (18%) and grade 3-4 thrombocytopenia by 4 (12%). Six patients were hospitalized due to febrile neutropenia. Despite the prophylactic use of hematopoietic growth factors, 8 (23.5%) patients required dose reduction due to myelosuppression. Grade 3 alopecia occurred in 14 (41%) patients, grade 3-4 nausea in 1 (3%), grade 2 fever in 3 (9%), grade 2-3 diarrhea in 2 ( 6%) and grade 2 allergic reaction in 1 (3%). CONCLUSION: We conclude that the combination of gemcitabine and ifosfamide is an active salvage regimen for the treatment of urothelial cancer and that the treatment also has a tolerable toxicity profile; it warrants further investigation in combination with CDDP in chemotherapy-naïve patients.

Weekly paclitaxel as first-line chemotherapy and trastuzumab in patients with advanced breast cancer. A Hellenic Cooperative Oncology Group phase II study.

AIM: To evaluate the activity and acute toxicity of the combination of weekly paclitaxel as first-line chemotherapy and trastuzumab, in patients with HER-2/neu overexpressing advanced breast cancer (ABC). BACKGROUND: Weekly paclitaxel has been shown to be a well tolerated treatment with considerable activity in patients with ABC. Clinical trials with transtuzumab, a humanized anti-p185 HER-2/neu monoclonal antibody have demonstrated that this agent produces objective responses in patients with ABC. PATIENTS AND METHODS: From December 1998 to April 2000, 34 patients with HER-2/neu overexpressing ABC were treated with weekly paclitaxel; given by one-hour infusion at a dose of 90 mg/m2 immediately followed by trastuzumab, 4 mg/kg as a loading dose and 2 mg/kg i.v. given over 30 min, thereafter weekly for at least 12 weeks. Expression of HER-2/neu was determined by immunohistochemical analysis on fixed, paraffin-embedded tissues. Eligible patients were required to have > or = 25% stained tumor cells. RESULTS: Thirty-three patients completed at least 12 weeks of combined treatment. After completion of the 12th week of treatment, four patients (12%) achieved complete and 17 (50%) partial response. Median duration of response was 11.6 months. More frequent side effects included anemia (56%). neutropenia (27%), peripheral neuropathy (78%), diarrhea (30%), alopecia (70%), arthralgias/myalgias (62%), fatigue (59%) and hypersensitivity reactions (62%). Median time to progression was nine months while median survival had not been reached CONCLUSIONS: The combination of weekly paclitaxel and trastuzumab is a safe and active regimen for patients with HER-2/neu overexpressing ABC. Randomized phase III studies with this combination are warranted.

Dose-dense sequential chemotherapy with epirubicin and paclitaxel in advanced breast cancer.

The purpose of this study was to evaluate the activity and toxicity profile of dose-dense sequential chemotherapy with epirubicin (EPI) and paclitaxel in advanced breast cancer (ABC). From January to September 1997, 41 patients with recurrent or metastatic (stage IV) breast cancer were enrolled in the study. Their median age was 57 (range, 33-77) years and median performance status 0 (range, 0-2). Twenty patients had received adjuvant chemotherapy. The chemotherapeutic regimen consisted of 4 cycles of EPI 110 mg/m2 every 2 weeks followed by 4 cycles of paclitaxel, 225 mg/m2 over 3 hours every 2 weeks. G-CSF was administered prophylactically on days 2-10 of each cycle. 34 (83.0%) patients completed all 8 cycles of chemotherapy. A total of 304 cycles were administered, 259 (85.0%) of them at full dose. Thirty (10.0%) cycles were delivered with a delay. The relative median dose intensities of EPI and paclitaxel were 0.95. Most common grade 3-4 side effects were anemia (15.0%) neutropenia (12.0%), thrombocytopenia (5.0%), nausea/vomiting (10.0%), febrile neutropenia (7.5%), and alopecia (90.0%). Overall, 8 (19.5%) patients achieved a complete and 15 (36.5%) a partial response. Median duration of response was 8.4 (range, 3.1-15.5+) months. After a median follow-up of 18.5 months, median time to progression was 8.7 (range, 0.5-21+) months; median survival has not been reached yet. Dose-dense sequential chemotherapy with EPI and paclitaxel shows promising activity as first-line treatment in ABC. Randomized studies comparing this type of chemotherapy with the classical administration of the two drugs together every 3 weeks are ongoing.

Malignant fibrous histiocytoma of the trunk metastatic to the liver: treatment with transcatheter intrahepatic chemoembolization.

We report a patient with symptomatic liver metastases as the sole site of recurrence of a previously resected malignant fibrous histiocytoma of the trunk. We treated the patient with two sessions of transcatheter chemoembolization. Tumor regression was achieved, and the patient remained free of symptoms 23 months after the diagnosis of liver involvement, when he died of acute myocardial infarction. To our knowledge, this is the only case of transcatheter chemoembolization of liver metastases from soft-tissue sarcoma reported in the literature. Although it is a single case, it shows that this method may be a promising therapy for this grave disease.

Dose-dense sequential adjuvant chemotherapy with epirubicin, paclitaxel and CMF in high-risk breast cancer.

Dose-dense sequential chemotherapy appears to be a promising approach in the management of patients with operable breast cancer. We evaluated the tolerability of such a novel chemotherapeutic regimen in high-risk patients. From February 1995 until September 1997, 49 women with histologically confirmed breast cancer and > or =10 involved axillary nodes were treated postoperatively with three cycles of epirubicin (110 mg/m(2)) followed by three cycles of paclitaxel (250 mg/m(2) in a 3-hour infusion) followed by three cycles of 'intensified' CMF (cyclophosphamide 840 mg/m(2), methotrexate 57 mg/m(2), fluorouracil 840 mg/m(2); E-T-CMF). All cycles were repeated every 2 weeks with G-CSF support. Ovarian ablation with monthly injections of triptorelin for 1 year was performed in premenopausal patients and tamoxifen was prescribed for 5 years to all women with positive receptor status after the completion of chemotherapy. A total of 456 cycles of chemotherapy were administered, 363 (80%) of them at full dose. Forty-seven (96%) patients received all 9 cycles of chemotherapy. Relative dose intensity of epirubicin was 0.98, of paclitaxel 0.97, of cyclophosphamide 0.99, of methotrexate 0.98 and of fluorouracil 0.99. Grade 3--4 toxicities included anemia (8%), leukopenia (8%), peripheral neuropathy (6%), neutropenia (4%), thrombocytopenia (4%), stomatitis (2%), diarrhea (2%), fatigue (2%) and hypersensitivity reaction (2%). Febrile neutropenia occurred in 2 patients. Alopecia was universal. After a median follow-up of 3 years, 11 women (22%) relapsed and 4 (8%) died. The 3-year actuarial disease-free survival rate was 72% and the 3-year overall survival rate 90%. The E-T-CMF regimen is well tolerated, as adjuvant treatment, in patients with operable breast cancer with promising activity and deserves further evaluation in phase III studies.

Ifosfamide plus oral etoposide salvage chemotherapy for platinum-resistant paclitaxel-pretreated ovarian cancer.

BACKGROUND: The prognosis of platinum resistant ovarian cancer is very poor and the treatment of choice has not been clearly defined. PATIENTS AND METHODS: We conducted a phase II study with the combination of ifosfamide i.v. at 2.25 g/m2 (days 1, 2) and etoposide per os at 100 mg daily (days 1-10) every four weeks. To be eligible for the study patients had to be resistant to platinum and paclitaxel pretreated. RESULTS: Forty-one patients entered the study. The median interval from the previous chemotherapy was 3.9 months. The median number of previous chemotherapeutic regimens was 2. Severe toxicities included neutropenia (41% of patients), leukopenia (29%) and thrombocytopenia (13%). Thirty-five patients are assessable for response. Nine patients responded (22% of the eligible, 26% of the assessable), four of them demonstrated complete response to chemotherapy (10% and 12%, respectively), while three patients demonstrated stabilization of their progressive disease. After a median follow-up of 18 months, time to progression is 3 months (range 0.9-14.4), duration of response is 9 months (2.5-11) and median survival is 13 months (2.5-37.4+). CONCLUSIONS: The combination of ifosfamide with oral etoposide appears to have significant but manageable toxicity and encouraging efficacy in platinum resistant ovarian cancer.

Gemcitabine and vinorelbine as second-line treatment in patients with metastatic breast cancer progressing after first-line taxane-based chemotherapy: a phase II study conducted by the Hellenic Cooperative Oncology Group.

BACKGROUND: Gemcitabine and vinorelbine have shown activity in breast cancer. A phase II trial was initiated in order to evaluate the response rate (RR) and time to progression (TTP) of the combination of the two drugs in patients with metastatic breast cancer progressing after first-line taxane-based chemotherapy. PATIENTS AND METHODS: Thirty-one patients were treated with the combination of gemcitabine 1000 mg/m2 days 1 + 8 and vinorelbine 30 mg/m2 days 1 + 8. The cycles were repeated every three weeks. RESULTS: Of 27 evaluable patients 1 (4%, 95% confidence interval (95% CI): 0.1%-19%) achieved complete remission (CR), five (18%; 95% CI: 6%-38%) partial remission (PR), eleven (40%; 95% CI: 22%-61%) stable disease and ten patients progressed. The median duration of response was six months (range 4-10+) and the median duration of disease stabilization was five months (range 2-22+). With a median follow-up of 16 months (range 0.4-22+) the median TTP was 3.5 months (range 0.4-22+) and the median survival was 9.5 months (range 0.4-22+). Grade 3-4 toxicities were granulocytopenia 15 patients (48%), rash 3 patients (10%), neuropathy 1 patient (3%) and thrombocytopenia 1 patient (3%). In conclusion the combination of gemcitabine/vinorelbine in the doses administered in this group of patients had a response rate of 22% and needs to be further evaluated in metastatic breast cancer.

Carboplatin plus paclitaxel in unknown primary carcinoma: a phase II Hellenic Cooperative Oncology Group Study.

PURPOSE: To evaluate the efficacy of the carboplatin/paclitaxel combination in patients with carcinoma of unknown primary site (CUP). PATIENTS AND METHODS: Seventy-seven consecutive CUP patients (45 women and 32 men; median age, 60 years) were treated with carboplatin at target area under the curve 6 mg/mL/min followed by paclitaxel 200 mg/m(2) as a 3-hour infusion and granulocyte colony-stimulating factor from days 5 to 12. Treatment courses were repeated every 3 weeks to a maximum of eight cycles. Forty-seven patients had adenocarcinomas, 27 had undifferentiated carcinomas, and three had squamous cell carcinomas. Thirty-three patients presented with liver, bone, or multiple organ metastases, 23 with predominantly nodal/pleural disease, and 19 (16 women) with peritoneal carcinomatosis. RESULTS: The overall response rate by intent-to-treat analysis was 38.7% (95% confidence interval, 27.5% to 49.9%). There were no differences in response between adenocarcinomas and undifferentiated carcinomas, but efficacy varied among clinical subsets. The response rates and median survival times in the three clinically defined subsets were 47.8% and 13 months, respectively, for patients with predominantly nodal/pleural disease, 68.4% and 15 months, respectively, in women with peritoneal carcinomatosis, and 15.1% and 10 months, respectively, in patients with visceral or disseminated metastases. Chemotherapy was well-tolerated. CONCLUSION: Carboplatin plus paclitaxel combination chemotherapy is effective in patients with predominantly nodal/pleural metastases of unknown primary carcinoma and in women with peritoneal carcinomatosis. However, in patients with liver, bone, or multiple organ involvement, the combination offers limited benefit. The investigation of novel treatment approaches is highly warranted for this group of patients.

Docetaxel and gemcitabine in anthracycline-resistant advanced breast cancer: a Hellenic Cooperative Oncology Group Phase II study.

A phase II study was conducted to evaluate the activity and toxicity profile of the combination of docetaxel and gemcitabine in anthracycline-resistant advanced breast cancer (ABC). Thirty-nine eligible patients with a median performance status of 1 (range, 0-2) were enrolled in the study. Treatment consisted of docetaxel 75 mg/m2 in a 1-hr infusion on day 1 preceded by gemcitabine 1000 mg/m2 over 30 min on days 1 and 8. One hundred eighty-one treatment cycles were administered, 113 (62.4%) of them at full dose. Relative dose intensity of gemcitabine and of docetaxel was 0.73 and 0.85, respectively. More common grade 3-4 toxicities included neutropenia (49%), anemia (10%), fatigue (10%), nausea/vomiting (8%), and alopecia (77%). Seven patients were hospitalized for febrile neutropenia. Granulocyte colony-stimulating factor (G-CSF) administration was required in 90% of patients. Overall, 14 patients (36%) responded, 3 (7.5%) of them completely. Median duration of response was 10.3 months (range, 4.6-17.5+). Median time to progression was 7 months (range, 0.2-17.5+) and median survival 12.7 months (range, 2-20.5+). In conclusion, the combination of docetaxel and gemcitabine, as used in the present study, has moderate activity in anthracycline-resistant ABC. Future studies should incorporate prophylactic administration of G-CSF to reduce the incidence of febrile neutropenia and maintain dose intensity.
