ReviewA review of the efficacy and safety of docetaxel as monotherapy in metastatic breast cancer.
To date, although statistically significant, the overall impact of adjuvant chemotherapy on the survival of women with nonmetastatic breast cancer has been disappointing. Hence, new agents that have shown good activity against metastatic disease should be assessed quickly in the adjuvant setting. Docetaxel (Taxotere; Rhône-Poulenc Rorer, Antony, France) is one of the most promising drugs that has emerged in recent years, with phase II studies in previously untreated metastatic breast cancer indicating a high overall response rate of approximately 60%. ⋯ The high activity of docetaxel provides a compelling rationale for its study as a component of adjuvant therapies. Investigators in Brussels and Dublin have recently demonstrated the feasibility of two candidate adjuvant programs. Large phase II adjuvant trials involving docetaxel are now being assessed.

ReviewReview of paclitaxel/carboplatin in advanced non-small cell lung cancer.
The management of non-small cell lung cancer (NSCLC) has advanced in the last two decades. The greatest benefit has been achieved with the development of newer chemotherapeutic agents with single-agent response rates > or =20%. Recent research has focused on adding these newer agents to established drugs for NSCLC, like cisplatin and carboplatin, yielding notable improvement in response and survival rates. ⋯ Phase III trials are under way to establish the specific role of this regimen in NSCLC. The success of this combination also is being expanded through studies investigating its combination in triplets with newer agents, with follow-up therapy via sequential regimens, and by the addition of biologically based treatments. The results of these trials will determine the preferred treatment approach to NSCLC for the next decade.

ReviewConcurrent paclitaxel, carboplatin, and radiation therapy for locally advanced non-small cell lung cancer.
Combination chemotherapy plus radiation therapy for non-small cell lung cancer has several theoretical advantages: the potential of chemotherapy to radiosensitize tumors, the possibility of improved local control due to combined treatment, and the opportunity for spatial cooperation, attacking disease both locally and systemically and thus potentially increasing response and, ultimately, survival. The combination of radiotherapy plus standard chemotherapy (etoposide plus cisplatin) has yielded limited success; therefore, new and novel chemotherapies have been sought. ⋯ Concurrent paclitaxel/carboplatin/radiotherapy appears to offer a relatively safe and more active regimen to control local and metastatic non-small cell lung cancer than the current standard. This report reviews the range of experience with paclitaxel-based combined-modality therapy.

ReviewPaclitaxel plus carboplatin in the treatment of ovarian cancer.
Two large, prospective randomized trials by the Gynecologic Oncology Group and the European Organization for Research and Treatment of Cancer have demonstrated the superiority of paclitaxel (Taxol; Bristol-Myers Squibb Company, Princeton, NJ)/cisplatin compared with cisplatin/cyclophosphamide in previously untreated patients with advanced ovarian cancer. Patients receiving the paclitaxel combination had a higher overall response rate, a longer time to disease progression, and prolonged median survival. In an effort to reduce toxicity, investigators developed combinations of carboplatin/paclitaxel that were found by phase I/II trials to have activity comparable to cisplatin/paclitaxel but with less toxicity. ⋯ The Gynecologic Oncology Group has completed a randomized comparison of three versus six cycles of paclitaxel/carboplatin in early stage disease. This study will be followed by a trial in which all patients with poor-prognosis, early stage ovarian cancer receive three cycles of paclitaxel/carboplatin followed by randomization to no further treatment or to weekly paclitaxel. The combination of paclitaxel/carboplatin is currently the preferred regimen for the treatment of ovarian cancer.

ReviewCombining new agents with anthracyclines in metastatic breast cancer: an overview of recent findings.
Historically, doxorubicin has been the most effective single agent in metastatic breast cancer, and the combination of doxorubicin with other active agents (as in the 5-fluorouracil/doxorubicin/cyclophosphamide protocol) has improved patient outcome. Results from phase II and several recent phase III studies provide evidence that new agents are also highly active in the treatment of metastatic breast cancer and suggest that they would be active in combination regimens with the anthracyclines. ⋯ Studies to date indicate that this high response rate is achieved without accompanying cardiotoxicity. Several other new agents, notably, paclitaxel, vinorelbine, and gemcitabine, also have been evaluated in combination with the anthracyclines.
