The therapeutic efficacy and toxicity of sequential methotrexate and 5-fluorouracil in 64 inoperable gastric cancer patients are reported. An intermediate-dose treatment was given to 48 patients, and a low-dose treatment to 16 patients. In the intermediate-dose treatment, leukopenia was observed in 11 patients, nausea and vomiting in six patients and diarrhea and stomatitis in two patients each. In the low-dose treatment, no patient developed toxic symptoms of grade 3 or 4. All 9 responders had adenocarcinoma of the poorly differentiated type and the response rate in patients who belonged to this type was 32.1%.

High response rates have been reported in the treatment of advanced gastric cancer with epirubicin, cisplatin and continuous infusion 5-fluorouracil (ECF), including instances of unresectable disease being rendered operable by chemotherapy. We report our experience with ECF as neoadjuvant treatment in gastric and lower oesophageal carcinoma. Twenty-seven patients were treated, of whom ten (37%) had carcinoma of the stomach and 17 (63%) tumours of the lower oesophagus. Histology in the majority of cases, 21 (78%), was adenocarcinoma. Before chemotherapy ten patients (37%) had evidence of initially unresectable locally advanced disease, 16 (59%) had localised disease only and one patient (4%) had a localised primary with a single liver metastasis. Epirubicin (50 mg m(-2) i.v.) and cisplatin (60 mg m(-2) i.v.) were administered every 3 weeks for four cycles together with a continuous 12 week infusion of 5-fluorouracil (200 mg m(-2) day(-1)). Fifteen of 24 assessable patients (62%) had symptomatic improvement on chemotherapy. On combined surgical and/or radiological assessment, 15 of the 27 patients (56%) had objective evidence of tumour response. In all patients assessment for radical surgery was made following chemotherapy. Eighteen patients (67%) proceeded to operation: of these, 11 had complete resection of their disease, one had a histologically incomplete resection and six were found to have unresectable disease. No pathological complete responses were observed. Only one of the ten patients with locally advanced disease achieved complete surgical resection after chemotherapy. At a median follow-up of 36 months from date of diagnosis (range 30-47 months), 19 of the 27 patients (70%) have died. Of 11 patients who had a complete surgical resection, one died post-operatively, three have subsequently relapsed (of whom two have died) and seven remain disease free. Toxicity from treatment was mild and included emesis, myelosuppression, stomatitis and exfoliation. Myelosuppression caused modification of treatment in 14 of 108 chemotherapy cycles (13%). There was one surgical death but no chemotherapy-related deaths. These early results show encouraging symptomatic and objective responses of gastro-oesophageal carcinoma to ECF, but provide no instances of ECF achieving complete pathological response. Only randomised trials can establish the role of neoadjuvant ECF chemotherapy in both initially resectable and unresectable carcinoma of the stomach and lower oesophagus.

The aim of this study was to evaluate the clinical efficacy and safety of docetaxel (Taxotere) in patients with adenocarcinoma of the upper gastrointestinal tract previously untreated with cytotoxic chemotherapy. Docetaxel 100 mg m-2 was administered as a 1 hour intravenous (IV) infusion every 3 weeks to 41 patients. Patients were premedicated prior to each course with dexamethasone, diphenhydramine and cimetidine. Clinical response and toxicity were determined. Objective responses were seen in seven of 41 eligible patients (two complete responses [CRs] and five partial responses [PRs], for an objective response rate of 17% (90% confidence interval [CI], 8% to 30%). The most common toxicity was grade 4 neutropenia, which occurred in 88% of patients; 46% of patients required a dose reduction following an episode of neutropenic fever requiring antibiotic therapy. Additional patients have had reversible grade 3-4 toxicities including nausea, vomiting, stomatitis, diarrhea, fatigue and peripheral neuropathy. Ten patients have had grade 1-3 hypersensitivity reactions. Alopecia has been seen in the majority of patients. Fluid retention grade 1-3 has been observed in patients. Docetaxel administered on this schedule is an active agent in adenocarcinomas of the upper gastrointestinal tract. Further investigation of this drug should be conducted in multi-drug combination programs.

Previous report suggested that weekly 24-hour infusion of high-dose 5-fluorouracil (5-FU) and leucovorin is a highly active and relatively low toxic regimen for the treatment of colorectal carcinoma (J Clin Oncol 9: 625-30, 1991). This phase II study was conducted to test this important observation by a slightly modified regimen in a larger group of patients. The weekly HDFL regimen consisted of 5-FU 2600 mg/m2/week and leucovorin 300 mg/m2/week (maximum 500 mg) in a 24-hour intravenous infusion. Between February 1992 and December 1995, a total of 42 patients with non-resectable, recurrent or metastatic colorectal adenocarcinoma were enrolled onto the study. Twenty-nine (69.0%) patients had prior exposure to lower-dose 5-FU. There were 22 men and 20 women with median age of 60 (20-75) years. They received a total of 855 and an average of 20.4 (4 to 65) courses of HDFL chemotherapy. Most patients were treated at outpatient clinics and the drugs were infused by an ambulatory pump system via a Port-A catheter. The median duration of follow-up was 22 months. ECOG Gr 2-3 stomatitis, diarrhea, nausea, and vomiting developed in 6 (14.3%), 6 (14.3%), 5 (11.9%), and 5 (11.9%) patients, respectively. Twenty (47.6%) patients had developed hand-foot syndrome. There was no hematological toxicities except 3 (7.1%) patients developed ECOG Gr 1-2 leucopenia. The overall response rate was 42.9% (28%-59%, 95% C.I.) with 2 complete responses and 16 partial responses. Eight (61.5%; 31%-86%, 95% C.I.) of 13 patients, who had no previous 5-FU exposure, responded (1 complete response, 7 partial responses). Ten (34.5%, 17%-54%, 95% C.I.) of 29 patients, who had had previous lower-dose 5-FU exposure, responded (1 complete response and 9 partial responses). The median duration of response was 5 months (1+ to 23+ months). The median overall survival of the whole group of 42 patients and the 18 responders was 10 and 22 months, respectively. Our data supported the original results of HDFL regimen in the treatment of colorectal cancers. HDFL regimen can be used either as first-line or second-line treatment for non-resectable, recurrent or metastatic colorectal cancers.

We report here the generation of recombinant vesicular stomatitis virus (VSV) able to produce the suicide gene product thymidine kinase (TK) or cytokine interleukin 4 (IL-4). In vitro cells infected with the engineered viruses expressed remarkably high levels of biologically active TK or IL-4 and showed no defects in replication compared to the wild-type virus. Recombinant viruses retained their ability to induce potent apoptosis in a variety of cancer cells, while normal cells were evidently more resistant to infection and were completely protected by interferon. Significantly, following direct intratumoral inoculation, VSV expressing either TK or IL-4 exhibited considerably more oncolytic activity against syngeneic breast or melanoma tumors in murine models than did the wild-type virus or control recombinant viruses expressing green fluorescent protein (GFP). Complete regression of a number of tumors was achieved, and increased granulocyte-infiltrating activity with concomitant, antitumor cytotoxic T-cell responses was observed. Aside from discovering greater oncolytic activity following direct intratumoral inoculation, however, we also established that VSV expressing IL-4 or TK, but not GFP, was able to exert enhanced antitumor activity against metastatic disease. Following intravenous administration of the recombinant viruses, immunocompetent BALB/c mice inoculated with mammary adenocarcinoma exhibited prolonged survival against lethal lung metastasis. Our data demonstrate the validity of developing novel types of engineered VSV for recombinant protein production and as a gene therapy vector for the treatment of malignant and other disease.

A phase II trial was performed to evaluate the efficacy and toxicity of the novel combination of vinorelbine and paclitaxel as first-line chemotherapy in patients with stages IIIB and IV non-small-cell lung cancer. From January 1997 to September 1999, 34 patients (9 stage IIIB and 25 stage IV) received a regimen consisting of the following: vinorelbine 30 mg/m2 20 minutes intravenous (i.v.) infusion, days 1 and 8; and paclitaxel 135 mg/m2 3-hour i.v. (starting 1 hour after vinorelbine) on day 1. Cycles were repeated every 28 days until progression of disease or unacceptable toxicity development. The median age was 57 years (range 41-70 years); median performance status was 1. Histology was as follows: squamous cell in 24 (71%), large cell in 1 (3%), and adenocarcinoma in 9 (26%). All patients are evaluable for toxicity, whereas 30 are evaluable for response (4 patients refused treatment). Objective response was recorded in 4 of 30 patients (13%, 95% CI 1-25%). No complete response was observed. Partial response was recorded in 4 patients (13%), no change in 10 patients (34%), and progressive disease in 16 patients (53%). The median time to treatment failure was 4 months and median survival was 9 months. The limiting toxicity was myelosuppression: leukopenia in 23 patients (68%), whereas neutropenia was observed in 25 patients (78%). Peripheral neurotoxicity developed in 14 patients (41%) (without G3 or G4 episodes), and constipation (G1-G2: 10 patients), myalgia (G1-G2: 11 patients), diarrhea (G1-G2: 7 patients), and stomatitis were observed in 7 patients. Vinorelbine-paclitaxel combination showed only modest activity against locoregionally advanced or metastatic NSCLC.

This study was designed to determine the safety and efficacy of the combination therapy of gemcitabine plus carboplatin when used as a second-line treatment in patients with metastatic breast cancer (MBC). From February 2002 to May 2003, 30 previously treated patients with adenocarcinoma of the breast received gemcitabine 1000 mg/m2 on days 1 and 8 plus carboplatin to an area under the curve (AUC) of 5 on day 1. The carboplatin dose was changed to an AUC of 4.5 because of toxicity, with cycles repeated every 3 weeks. Among 30 patients enrolled, 25 were assessable for response rate (RR). There was no complete response; 9 patients (30%) had partial response, for an overall RR of 30%. The median time to progression for the study group was 20.47 weeks (range, 8-46 weeks). Treatment-related toxicities included grade 3/4 neutropenia in 50% of patients (20% of whom had febrile neutropenia), grade 3/4 anemia in 26.6% of patients, and grade 3/4 thrombocytopenia in 30%. Eleven patients (36.67%) had grade 1 alopecia, and 1 patient (3.33%) had grade 2 alopecia. Moderate nausea was observed in 8 patients (26.67%), and vomiting occurred in 7 patients. Four patients had asthenia and 3 (10%) experienced stomatitis. Three patients discontinued treatment because of hematologic toxicity (thrombocytopenia) and 2 patients are still receiving treatment. Carboplatin plus gemcitabine is an active combination for patients with MBC despite significant but manageable hematologic toxicity.

A cloned cell line that spontaneously polarizes in standard glucose-containing media was derived from a single cell of the adenocarcinoma cell line HT-29. The cloned line, designated HT-29/cl.f8, has remained stable over 2 yr in culture, maintained high transepithelial resistance (300 ohm cm(2) or higher), and correctly sorted influenza virus and vesicular stomatitis virus to apical or basolateral domains, respectively. The newly cloned cells also displayed apical microvilli, tight junctions, and desmosomes, the morphological characteristics of mature epithelia. The cloned HT-29/cl.f8 cells function as epithelial enterocytes as shown by the apical expression of intestinal alkaline phosphatase, the expression of vimentin and cytokeratin, and lack of expression of mucin. We propose that the newly cloned HT-29/cl.f8 cells offer a viable alternative for studies of enterocyte function that will readily yield interpretable data not complicated by cell alterations due to the presence of drugs or chemicals that induce differentiation.

The purpose of this study was to define the maximal tolerated dose (MTD), extramedullary toxicities, and pharmacokinetics of docetaxel combined with high-dose melphalan and carboplatin with autologous hematopoietic progenitor cell support. Fifty-nine patients with advanced refractory malignancy (32 breast cancer, 10 non-Hodgkin lymphoma, 6 germ cell tumors, 4 Hodgkin disease, 4 ovarian cancer, 2 sarcoma, and 1 unknown primary adenocarcinoma) with a median of 3 prior chemotherapy regimens and a median of 3 organs involved were enrolled. Treatment included docetaxel (150-550 mg/m2 infused over 2 hours on day -6), melphalan (150-165 mg/m2 infused over 15 minutes from day -5 to -3), and carboplatin (1000-1300 mg/m2 as a 72-hour continuous infusion from day -5). Five patients died from direct regimen-related organ toxicity (2 capillary leak syndrome, 2 enterocolitis, and 1 hepatic toxicity), and 1 additional patient died from pulmonary aspergillosis. The docetaxel MTD was defined as 400 mg/m 2 , combined with melphalan (150 mg/m2 ) and carboplatin (1000 mg/m2 ). The MTD cohort was expanded to enroll a total of 26 patients, 1 of whom died from toxic enterocolitis. The remaining 25 patients presented the following extramedullary toxicity profile, which was manageable and largely reversible: stomatitis, myoarthralgias, peripheral neuropathy, gastrointestinal and cutaneous toxicities, and syndrome of inappropriate antidiuretic hormone secretion. Docetaxel exhibited linear pharmacokinetics in the dose range tested (150-550 mg/m2 ). Pharmacodynamic correlations were noted between the docetaxel area under the curve and peripheral neuropathy or stomatitis. The response rate among 38 patients with measurable disease was 95%, with 47% complete responses. At a median follow-up of 26 months (range, 7-72 months), the 3-year event-free survival and overall survival were 26% and 36%, respectively. In conclusion, a 4-fold dose escalation of docetaxel, combined with melphalan and carboplatin, is feasible with autologous hematopoietic progenitor cell support. The notable activity of this regimen in treatment-refractory patients warrants its further evaluation.

From February, 2001 to September, 2002, the Southwest Oncology Group (SWOG) accrued 65 patients with advanced gastric adenocarcinoma to a phase II trial of weekly 5-FU, leucovorin, and the orally-administered uridine analog PN401. Of these 65 patients, 57 were assessable for survival and toxicity, which were the endpoints for the study. Treatment consisted of the administration of 1200 mg/m(2) of 5-FU, 500 mg/m(2) of leucovorin, and 6 grams of PN401 every 8 h, beginning 8 h after the completion of the 5-FU infusion, and continuing for a total of 8 doses (48 grams) during each weekly chemotherapy session. Therapy was delivered for six weeks out of every 8-week treatment cycle. The gastrointestinal toxicity of this regimen was mild with 2 patients experiencing grade 3 stomatitis, and 6 patients having grade 3 diarrhea; and the hematologic toxicity was acceptable with 6 of 57 patients found to have had grade 3 or 4 leukopenia, and 14 of 57 patients experiencing grade 3 or 4 neutropenia. There were two deaths judged possibly related to treatment; one in a patient who experienced a variety of Grade 2 gastrointestinal toxicities and died at home with an unknown cause of death; and a second patient who also died at home, and for whom treatment-related sepsis could not be ruled out. The overall median survival was 7.2 months. The ability to safely deliver twice the usual dose of 5-FU with leucovorin on a weekly schedule suggests that oral uridine analog supplementation with PN401 may enhance the therapeutic index of the fluoropyrimidines.
