Intergroup Trial

Purpose: Between February 1993 and September 1995, 739 patients with metastatic breast cancer were entered on an Intergroup trial (E1193) comparing doxorubicin (60 mg/m2), paclitaxel (175 mg/m2/24 h), and the combination of doxorubicin and paclitaxel (AT, 50 mg/m2 and 150 mg/m2/24 h, plus granulocyte colony-stimulating factor 5 mg/kg) as first-line therapy. Patients receiving single-agent doxorubicin or paclitaxel were crossed over to the other agent at time of progression. Patients and Methods: Patients were well balanced for on-study characteristics. Results: Responses (complete response and partial response) were seen in 36% of doxorubicin, 34% of paclitaxel, and 47% of AT patients (P = .84 for doxorubicin v paclitaxel, P = .007 for v AT, P = .004 for paclitaxel v AT). Median time to treatment failure (TTF) is 5.8, 6.0, and 8.0 months for doxorubicin, paclitaxel, and AT, respectively (P = .68 for doxorubicin v paclitaxel, P = .003 for doxorubicin v AT, P = .009 for paclitaxel v AT). Median survivals are 18.9 months for patients taking doxorubicin, 22.2 months for patients taking paclitaxel, and 22.0 months for patients taking AT (P = not significant). Responses were seen in 20% of patients crossing from doxorubicin → paclitaxel and 22% of patients crossing from paclitaxel → doxorubicin (P = not significant). Changes in global quality-of-life measurements from on-study to week 16 were similar in all three groups. Conclusion: (1) doxorubicin and paclitaxel, in the doses used here, have equivalent activity; (2) the combination of AT results in superior overall response rates and time to TTF; and (3) despite these results, combination therapy with AT did not improve either survival or quality of life compared to sequential single-agent therapy.

Dose Levels

PURPOSE: To determine the efficacy, safety, pharmacokinetics, and effect on serum angiogenic growth factors of two dose levels of thalidomide in patients with metastatic breast cancer. PATIENTS AND METHODS: Twenty-eight patients with progressive metastatic breast cancer were randomized to receive either daily 200 mg of thalidomide or 800 mg to be escalated to 1,200 mg. Fourteen heavily pretreated patients were assigned to each dose level. Each cycle consisted of 8 weeks of treatment. Pharmacokinetics and growth factor serum levels were evaluated. RESULTS: No patient had a true partial or complete response. On the 800-mg arm, 13 patients had progressive disease at or before 8 weeks of treatment and one refused to continue treatment. The dose was reduced because of somnolence to 600 mg for five patients and to 400 mg for two and was increased for one to 1,000 mg and for four to 1,200 mg. On the 200-mg arm, 12 patients had progressive disease at or before 8 weeks and two had stable disease at 8 weeks, of whom one was removed from study at week 11 because of grade 3 neuropathy and the other had progressive disease at week 16. Dose-limiting toxicities included somnolence and neuropathy. Adverse events that did not require dose or schedule modifications included constipation, fatigue, dry mouth, dizziness, nausea, anorexia, arrhythmia, headaches, skin rash, hypotension, and neutropenia. Evaluation of circulating angiogenic factors and pharmacokinetic studies failed to provide insight into the reason for the lack of efficacy. CONCLUSION: Single-agent thalidomide has little or no activity in patients with heavily pretreated breast cancer. Further studies that include different patient populations and/or combinations with other agents might be performed at the lower dose levels.

e12018 Background: Addition of capecitabine to docetaxel improves survival outcomes compared with single agent docetaxel in metastatic breast cancer (MBC). In this study we analyzed efficacy of maintenance therapy with single agent capecitabine after six cycles of docetaxel/capecitabine chemotherapy in MBC patients. Methods: Patients with metastatic HER2 negative breast cancer were included. Six cycles of docetaxel (75mg/m2 q3wk) / capecitabine (1650mg/m2/day on days 1 to 14) followed by capecitabine (2000 mg/m2/day on days 1 to 14) were administered. Demographic features, progression free (PFS) and overall survival (OS) and response to treatment were recorded. Results: Fifty-four patients were included. Thirty-five patients (65%) were postmenopausal, and 40 (74%) were ER/PR positive. Median age was 53 (range 28 – 70). Number of metastatic sites was one in 23 patients, two in 21, three or more in 10 patients. Most common metastatic sites were bone (67%), lymph nodes (33%), lungs (30%), liver (13%); 13 patients (24%) had bone only disease. Forty-four (81.5%) patients received treatment in first-line, 10 (18.5%) received in second line setting. Median number of cycles applied (including docetaxel/capecitabine combination) was 9 (range 2 – 31, total 576). Median PFS was 9 months (10.4 for hormone receptor positive, 7.3 for negative patients) and median OS was 28 months. Objective response was assessable in 38 patients. Overall response rate (partial + complete response) was 42.6% (95% CI 29.6 – 55.6) with 1 complete response. Toxicities were evaluated in 41 patients; grade 3/4 neutropenia was observed in 10% and grade 3/4 hand-foot syndrome was observed in 24% of patients. Dose reduction was performed in capecitabine in 37%, and in docetaxel in 20% of patients. Conclusions: Maintenance with single agent capecitabine therapy after six cycles of docetaxel/capecitabine chemotherapy is an effective and tolerable treatment option for HER2 negative MBC patients.

PURPOSE: Gemcitabine has promising single-agent activity in advanced breast disease. The aim of this phase II study was to determine the efficacy, toxicity, and pharmacokinetic profile of gemcitabine administered with doxorubicin as first-line treatment in patients with metastatic breast cancer. PATIENTS AND METHODS: Of the 42 women with metastatic breast cancer (age 33 to 74 years; mean age, 55 years), 13 were chemotherapy-naive and 29 had received adjuvant chemotherapy. Gemcitabine (800 or 1,000 mg/m2) and doxorubicin (25 mg/m2) were administered intravenously on days 1, 8, and 15 of each 28-day cycle. Blood samples were drawn on day 8 of cycles 1, 2, and 3 and of subsequent odd cycles for gemcitabine pharmacokinetic determinations and before and after the first dose of cycle 1 or 2 for doxorubicin determinations. RESULTS: There were three complete and 20 partial responses, for an overall response rate of 55% (95% confidence interval [CI], 40% to 70%) and a complete response rate of 7%. The median survival time for all 42 patients was 27 months (95% CI, 13.4 to 30.0 months) and the 1-year survival rate was 80%. Toxicity was mainly hematologic. The disposition of both drugs was unchanged when they were administered on the same day compared with when they were given singly. CONCLUSION: The combination of gemcitabine (800 mg/m2) and doxorubicin (25 mg/m2) can be safely administered using a weekly schedule. The disposition of both drugs is unchanged when they are administered on the same day. This combination shows promising activity with acceptable toxicity compared with other combination therapies.

Intent To Treat

Purpose Preclinical studies in ErbB2-positive cell lines demonstrated a synergistic interaction between lapatinib and trastuzumab, suggesting that dual blockade is more effective than a single agent alone. EGF104900 compared the activity of lapatinib alone or in combination with trastuzumab in patients with ErbB2-positive, trastuzumab-refractory metastatic breast cancer (MBC). Patients and Methods Patients with ErbB2-positive MBC who experienced progression on prior trastuzumab-containing regimens were randomly assigned to receive either lapatinib alone or in combination with trastuzumab. The primary end point was progression-free survival (PFS). Secondary efficacy end points included overall response rate (ORR), clinical benefit rate (CBR; complete response, partial response, and stable disease for ≥ 24 weeks), and overall survival (OS). Results In the intent-to-treat population (N = 296) who received a median of three prior trastuzumab-containing regimens, the combination of lapatinib with trastuzumab was superior to lapatinib alone for PFS (hazard ratio [HR] = 0.73; 95% CI, 0.57 to 0.93; P = .008) and CBR (24.7% in the combination arm v 12.4% in the monotherapy arm; P = .01). A trend for improved OS in the combination arm was observed (HR = 0.75; 95% CI, 0.53 to 1.07; P = .106). There was no difference in ORR (10.3% in the combination arm v 6.9% in the monotherapy arm; P = .46). The most frequent adverse events were diarrhea, rash, nausea, and fatigue; diarrhea was higher in the combination arm (P = .03). The incidence of symptomatic and asymptomatic cardiac events was low (combination therapy = 2% and 3.4%; monotherapy = 0.7% and 1.4%, respectively). Conclusion Despite disease progression on prior trastuzumab-based therapy, lapatinib in combination with trastuzumab significantly improved PFS and CBR versus lapatinib alone, thus offering a chemotherapy-free option with an acceptable safety profile to patients with ErbB2-positive MBC.

Breast cancer is the main source of death among women. Currently, 77% of women diagnosed with breast cancer are age 50 and older; however, it is projected that approximately 66% of the new cases diagnosed will occur in women younger than 65. Several clinical trials have assessed the wellbeing and adequacy of taxanes along with their tolerability in patients with metastatic cancer (MBC) The overview of these Paclitaxel and Docetaxel, the mechanism of action, pharmacokinetics and pharmacodynamics, dose and administration, adverse effects, clinical potency, and sufferable profiles combination therapies, the pathological complete response of these taxanes are included. The different novel formulations of taxanes are formulated from nanoparticles, polyglutamate, liposomes to improve the wellbeing and adequacy taxanes to reduce their toxicities. Single-agent research located with docetaxel and paclitaxel in metastatic breast most cancers show clinically huge antitumor motion even in the advanced stage, heavily pretreated, safe, as properly as in refractory diseases. This action is likewise clear with taxane-based combination regimens. Serious hematologic and nonhematologic toxicities are incompatible, with different toxicities noted dependent on the portion and weekly regimen selected.  Weekly docetaxel and paclitaxel regimens speak to important helpful treatment options for women suffering from metastatic breast cancer and have entered assessment as a major aspect of adjuvant treatment for this disease Toxicity associated with taxanes chemotherapy are based totally on the dose schedules and weekly regimen selected and the most frequent toxicities related with these marketers include myalgia, peripheral neuropathy, neutropenia, etc Docetaxel retains in tumor cells for longer duration when compared to paclitaxel because of its slow efflux and large amounts of uptake into the cell which explains its more benefits when compared to paclitaxel. Clinical studies conducted so far suggested a more benefit to risk ratio for docetaxel when compared to paclitaxel. This article reviews mainly different actions exhibited by taxanes in the therapy of metastatic breast cancer and others on stages of cancer along with the toxicities associated with these agents.

PurposeWe conducted a cooperative group phase II study to assess antitumor activity and toxicity of sorafenib in patients with metastatic breast cancer (MBC) who had received prior treatment for their disease.Patient and MethodsPatients were eligible if they had measurable disease and had previously received an anthracycline and/or a taxane in the neoadjuvant, adjuvant, or metastatic setting. The primary end point of the study was tumor response per Response Evaluation Criteria in Solid Tumors (RECIST). The study was designed in two stages. Sorafenib was administered as 400 mg twice daily on days 1 through 28 of each 4-week cycle.ResultsTwenty-three patients were enrolled with a median age of 54 years (range, 37 to 70 years). Twenty-two (96%) had prior anthracycline treatment and 16 (70%) had prior taxane treatment. Patients received sorafenib for a median of two cycles (range, one to 15 cycles) with a median follow-up of 2.4 years (range, 2.2 to 2.6 years). There were no grade 4 toxicities and few grade 3 toxicities. Among the 20 patients eligible for efficacy analysis, no patients experienced a partial response or complete response per RECIST criteria. Thus, the trial stopped at the end of the first stage per study design. Two patients (10%; 90% CI, 1.8% to 28.3%) achieved stable disease lasting longer than 6 months.ConclusionSorafenib as a single agent, although well tolerated, did not exhibit activity when measured by tumor shrinkage in patients with MBC who had received prior treatment. Further research should focus on combinations with standard therapy and end points more sensitive to effects of targeted agents, such as disease stabilization.
