Randomized Controlled Trial Multicenter Study Comparative Study Clinical TrialProspective and randomized trial of lipiodol-transcatheter arterial chemoembolization for treatment of hepatocellular carcinoma: a comparison of epirubicin and doxorubicin (second cooperative study). The Cooperative Study Group for Liver Cancer Treatment of Japan.
A randomized, controlled clinical trial was conducted to compare the use of epirubicin (EPI) and doxorubicin (DOX) in Lipiodol (Laboratoire Guerbet, Roissy-Charles-de-Gaulle Cedex, France)-transcatheter arterial chemoembolization as a treatment of hepatocellular carcinoma. One hundred ninety-two hospitals participated, and 415 patients were enrolled in the study during the period between October 1989 and December 1990. The patients were randomly allocated to group A (EPI) or group B (DOX) by a centralized telephone registration. ⋯ The change in the serum alpha-fetoprotein level, the extent of Lipiodol accumulation in the tumor, and the extent of tumor reduction after the treatment did not show any significant differences between the groups. The white blood cell count in group B showed a tendency to decrease slightly more than in group A at 3 weeks after Lipiodol-transcatheter arterial chemoembolization. In conclusion, there was no statistically significant difference between the survival curves of the EPI and DOX groups in Lipiodol-transcatheter arterial embolization treatment of hepatocellular carcinoma.

Randomized Controlled Trial Multicenter Study Clinical TrialClinical pharmacology of carboplatin administered in combination with paclitaxel.
The clinical pharmacology of carboplatin (C) administered with paclitaxel (Taxol; Bristol-Myers Squibb Company, Princeton, NJ) (P) was investigated in two phase I studies undertaken in 83 previously untreated patients with either non-small cell lung cancer or ovarian cancer. Carboplatin was administered over 30 minutes and paclitaxel over 3 hours. Both agents were given every 4 weeks. ⋯ There is also a protective effect exerted by paclitaxel on carboplatin-related toxicity (ie, thrombocytopenia). The clear protective effect of paclitaxel in this combination suggests that it is possible to reduce the dose interval to 3 weeks. Studies are in progress to test this hypothesis and to investigate the underlying pharmacologic interactions.

Review Randomized Controlled Trial Comparative Study Clinical TrialThe North American experience with paclitaxel combined with cisplatin or carboplatin in lung cancer.
Paclitaxel (Taxol; Bristol-Myers Squibb Company, Princeton, NJ) is a new cytotoxic chemotherapeutic agent with a novel mechanism of action. Single-agent paclitaxel studies have shown promising activity in both small cell and non-small cell lung cancers. In non-small cell lung cancer, response rates of 22% to 26% and 1-year survival rates of 40% were reported with both 3-hour and 24-hour infusions of paclitaxel. ⋯ Thrombocytopenia occurred less frequently than expected. One completed randomized study showed that the paclitaxel/cisplatin regimen was superior to the etoposide/cisplatin regimen with respect to response rate and survival. Additional randomized studies are necessary to determine whether the combinations are superior to single-agent paclitaxel, to define the optimal dose with the 3-hour infusion schedule, to define the optimal schedule (3 hours v 24 hours), and to determine whether paclitaxel can be combined with other new agents.

Randomized Controlled Trial Clinical TrialOne-hour paclitaxel in the treatment of non-small cell lung cancer.
This review describes studies with two paclitaxel (Taxol; Bristol-Myers Squibb Company, Princeton, NJ)-containing treatments for non-small cell lung cancer (NSCLC). In an ongoing study, 100 patients with previously untreated stage IIIB or IV NSCLC received combination therapy comprised of paclitaxel 225 mg/m2 via 1-hour infusion and carboplatin, dosed to an area under the concentration-time curve of 6.0. Both drugs were given intravenously and cycles were repeated every 21 days. ⋯ Grade 3/4 esophagitis was observed in 51% of participants and usually occurred during the final 2 weeks of combined-modality therapy. The combination of paclitaxel and carboplatin is active and well tolerated in patients with advanced NSCLC, and paclitaxel-based combined-modality therapy produced a high rate of complete and partial responses and encouraging survival data. Continued investigation and refinement of these regimens is ongoing.

Randomized Controlled Trial Clinical TrialPaclitaxel and carboplatin as neoadjuvant chemotherapy in operable (stage I and II) and locally advanced (stage IIIA-N2) non-small cell lung cancer.
In 1995, a randomized intergroup study of neoadjuvant chemotherapy followed by either surgery or radiotherapy in the treatment of non-small cell lung cancer was started under the auspices of the European Organization for Research and Treatment of Cancer (EORTC 08941). The objective of this study is to investigate whether surgery or radiotherapy represents superior locoregional treatment, in terms of survival and quality of life, for patients with stage IIIA(N2) non-small cell lung cancer who have achieved a response after three courses of neoadjuvant chemotherapy. A phase II side study will investigate the clinical and pathologic response rate (if applicable), as well as acute and late side effects during or after consecutive surgery and/or radiotherapy of combination paclitaxel (Taxol; Bristol-Myers Squibb Company, Princeton, NJ) and carboplatin. ⋯ Depending on the response rate and early and late side effects observed in this well-defined, prognostically favorable group of patients, it will be decided whether and how to use the same combination chemotherapy in an ongoing randomized trial currently being conducted by the Dutch Lung Cancer Study Group (DLCSG 94-2). In the latter trial, patients with stage I and II non-small cell lung cancer are randomized to immediate surgery or two courses of neoadjuvant chemotherapy. Responding patients will receive another two courses of chemotherapy before surgery; nonresponders will go directly to surgery.
