Combination chemotherapy with newer, more active drugs in patients with advanced and/or metastatic bladder cancer might show improved response rate and survival. Gemcitabine (GEM) and Epidoxorubicin (EPI) have demonstrated activity in this disease. In addition, experimental studies in vitro have shown that the two agents have additive-synergistic effects when used in combination. Our prior phase I dose-finding study in previously untreated patients with advanced or metastatic bladder cancer defined recommended doses for further trials of GEM 1000 mg/m2 and EPI 25 mg/m2 on days 1, 8 and 15 every 28 days. A phase II trial at this dose level was initiated in previously untreated patients to assess efficacy and toxicity. Eligible patients had measurable disease; Karnofsky performance status (PS) of > 40; no prior chemotherapy; and adequate bone marrow reserve, cardiac, hepatic and renal function. Thirty- one patients (22 males, 9 females) with median age of 64 (range 44-75) and median PS of 80 were accrued, and all were eligible. Twelve patients had T4N1-2 M0, 8 had lymph node only metastases, while 11 had visceral metastases (liver, bone, lung). A total of 181 cycles was administered (range 3-7 per patient). Major toxicities (WHO grade > or = 3) were: neutropenia in 5 patients, thrombocytopenia in 2 patients, and anemia in 2 patients. Three patients had febrile neutropenic episodes and only 3 patients required dose reduction. Grade 1-2 non-hematological toxicities included nausea/vomiting, stomatitis and alopecia. No cardiac toxicity was observed. Of the 30 response evaluable patients, 17 (57%) demonstrated a major response (3 complete and 14 partial) (95% CI: 39%-75%), 7 had stable disease (23%) and 6 progressed (20%). These preliminary results confirm the phase I observation that the combination of GEM--EPI is highly active in the treatment of advanced and metastatic bladder cancer with a favourable toxicity profile.

Based on the recommended phase II doses for doxorubicin (60 mg/m2) and docetaxel (60 mg/m2) and the National Surgical Adjuvant Breast and Bowel Project's (NSABP) experience with doxorubicin and cyclophosphamide (cyclophosphamide 600 mg/m2), we conducted a phase II trial at 18 institutions using doxorubicin/docetaxel/cyclophosphamide (ATC) given every 21 days, in preparation for a major adjuvant breast cancer study (NSABP B-30), in which ATC would be used. Eligibility requirements included measurable stage IIIB/IV breast cancer, performance status 0-2, normal left ventricular ejection fraction, and no prior chemotherapy for metastatic disease (nontaxane adjuvant chemotherapy was allowed if completed > 12 months before entry and if the cumulative dose of doxorubicin was =240 mg/m2). Eighty-nine patients were entered who ranged in age from 30-78 years (38.2% < 50 years; 61.8% =50 years). A total of 33.7% of patients had stage IIIB disease, and 66.3% had stage IV disease. Among the stage IV patients, 20.3% had received prior adjuvant chemotherapy. Dexamethasone premedication (8 mg p.o. b.i.d. for 3 days) and prophylactic ciprofloxacin (500 mg p.o. b.i.d. days 5-15) were used. Colony-stimulating growth factors were reserved for secondary prophylaxis after prolonged or febrile neutropenia (FN) or documented severe infection in a prior cycle. After a cumulative dose of doxorubicin 480 mg/m2, patients could continue with docetaxel/cyclophosphamide alone. Eighty-nine patients and 577 courses were evaluable for toxicity. Median time on study as of May 2002 was 36.5 months (range, 28-47 months). Febrile neutropenia occurred in 34 patients (38%); 8 developed FN in the absence of prior prophylactic growth factor support; 26 developed FN despite prior growth factor support (for one patient this information was unavailable). There were no septic deaths. One patient died from pulmonary embolism. Other grade 3/4 adverse events included: nausea (9%), vomiting (7%), stomatitis (6%), diarrhea (4%), arthralgia/myalgia (3%), and neurotoxicity (1%). Clinical congestive heart failure was seen in 3 patients (3.4%). Seventy-seven patients were evaluable for best response within 6 cycles of therapy. Thirteen patients (16.9%) had a complete response, 43 (55.8%) had a partial response, for an overall response rate of 72.7%. The median response duration was 23.8 months (95% CI, 16.2-37.8 months), and the median time to progression or death was 23.5 months (95% CI, 16.3-38.7 months). The median survival time was 35.6 months (95% CI, 26.6-39.4 months). The administration of ATC with primary ciprofloxacin and secondary colony-stimulating factor prophylaxis is feasible and active. Its value in the adjuvant setting is currently under investigation.

An 18- to 25-yr-old intact female Bengal tiger (Panthera tigris) was diagnosed antemortem and postmortem with nasopharyngeal myxosarcoma metastatic to the lung, chronic lymphoplasmacytic otitis media, and lymphoplasmacytic and eosinophilic stomatitis. Myxosarcomas are rare in domestic animals and seldom metastasize; this tumor has not been previously reported in an exotic felid. Computed tomography of the skull was used during the diagnoses.

Metastatic meningioma is a rare disease, which has no effective chemotherapy. We report on a treatment of this condition with Doxil, a liposomal doxorubicin formulation. A 60-year-old woman with massive pleuro-pulmonary metastases from recurrent cranial meningioma was treated with Doxil (50-37.5 mg/m2) for 18 months with near-complete resolution of metastases and disappearance of pleural fluid. The only significant toxicities observed were stomatitis and hand-foot syndrome, which resolved with dose reduction and increase of dosing intervals. Doxil was cleared very slowly in this patient with a monoexponential half-life of 108 h. The patient remains in near-complete response for 6 months after treatment discontinuation. This is the first report on an effective chemotherapy in a patient with typical metastatic meningioma. The exact mechanism accounting for such an effective drug action is not clear, but may be related to a particularly high microvascular permeability to the liposome carriers in these metastatic lesions.

A phase II study was conducted to assess the toxicity and response rate of vinorelbine (NavelbineR) combined with epirubicin and fluorouracil (NEF) in metastatic breast cancer. Vinorelbine was delivered at a dose of 25 mg/m2 on days 1 and 8, epirubicin at 60 mg/m2 on day 1 and fluorouracil at 600 mg/m2 on day 1, at 3-week intervals. Forty consecutive ambulant patients with breast cancer with measurable metastases were treated with a total of 310 cycles (median 8) as first-line therapy. The objective response rate was 83% (95% CI 71-95) (6/40 CR 15%, 27140 PR 68%). In 3 patients, CNS metastases were detected during NEF therapy those who had a partial response in their visceral metastases. Median time to progression was 13 months (95% CI 7-19) and estimated median survival time was 32 months. The main dose-limiting adverse effect, grade III-IV haematological toxicity, was reported in 92% of patients. One patient died of neutropenic sepsis. Grade III infections requiring hospitalization were observed in 8 patients (20%). Half of the patients complained of mild constipation, nausea or stomatitis, which were easily managed. Almost all patients had grade III alopecia. One patient with previous adjuvant anthracycline therapy (CEF x 9 two years earlier) developed fatal grade IV cardiac failure associated with pulmonary emboli 2 months after completion of NEF therapy (PR with 6 cycles). In line with the observations of others conducting phase II first-line trials combining vinorelbine and epirubicin, it is concluded that the NEF regimen is effective in metastatic breast cancer. Haematological toxicity, however, requires dose reductions in many patients. Furthermore, careful monitoring of cardiac function is necessary, particularly in patients who received prior adjuvant anthracycline therapy.

A 66-year-old man was found to have both advanced cancer of the middle thoracic esophagus and advanced cancer of the middle third of the stomach with paraaortic lymph node metastases. The prognosis was poor because of local advanced disease and distant metastasis. The patient was therefore given combined chemotherapy with TS-1 and cisplatin. TS-1 (80 mg/day) was administered on days 1 to 5, 8 to 12, 15 to 19, and 22 to 26 (weekday-on/weekend-off schedule), and cisplatin (70 mg/m2 intravenously over the course of 2 hours) was administered on days 1 and 15 of a 28-day cycle. After 2 courses of chemotherapy the esophageal lesion had a complete response, and the gastric lesion had a partial response (reduction ratio, 71.4%). However, stomatitis and anorexia of grade 2 (NCI-CTC) occurred. Two courses of TS-1 alone (80 mg/m2) were therefore given. The esophageal lesion continued to show a complete response and the gastric lesion a partial response (reduction ratio, 85.7%). There was no change in the para-aortic lymph node metastasis (No. 16a2 latero). No adverse reaction to chemotherapy was severer than grade 3, and a good response was obtained. These findings indicate that chemotherapy with a combination of TS-1 and cisplatin is effective against advanced esophageal cancer and advanced gastric cancer.

The effectiveness and toxicity of many drugs can vary depending on the time of administration in relation to 24-hour rhythms of biochemical, physiological and behavioural processes under the control of the circadian clock. Such chronopharmacological phenomena are influenced by not only the pharmacokinetics but also pharmacodynamics of medications. Chronotherapy is especially relevant when the risk and/or intensity of the symptoms of disease vary predictably over time as exemplified by allergic rhinitis, arthritis, asthma, myocardial infarction, congestive heart failure, stroke and peptic ulcer disease. Morning, once-daily administration of corticosteroids results in little adrenocortical suppression, while the same daily dose split into four equal doses to coincide with daily meals and bedtime results in significant hypothalamus-pituitary-adrenal axis suppression. In a randomised, multicentre trial involving patients with previously untreated metastases from colorectal cancer, the chronomodulated infusion of oxaliplatin, fluorouracil and folinic acid was compared with a constant-rate infusion method. Adverse effects such as stomatitis and peripheral sensory neuropathy were lower and objective response was higher with chronotherapy as compared with the fixed-rate infusion. The merit of chronomodulated infusion is supported by the 24-hour rhythm of DNA synthesis and the activity of dehydropyrimidine dehydrogenase, which brings about the intracellular catabolism of fluorouracil. On the other hand, haloperidol and selective serotonin reuptake inhibitors have diverse effects on sleep continuity and nocturnal arousals. Although interferon also alters the clock function, this disruptive effect can be overcome by devising an administration regimen that minimises adverse drug effects on clock function. Thus, one approach to increasing the efficiency of pharmacotherapy is the administration of drugs at times at which they are most effective and/or best tolerated.

Ideally, an oncolytic virus will replicate preferentially in malignant cells, have the ability to treat disseminated metastases, and ultimately be cleared by the patient. Here we present evidence that the attenuated vesicular stomatitis strains, AV1 and AV2, embody all of these traits. We uncover the mechanism by which these mutants are selectively attenuated in interferon-responsive cells while remaining highly lytic in 80% of human tumor cell lines tested. AV1 and AV2 were tested in a xenograft model of human ovarian cancer and in an immune competent mouse model of metastatic colon cancer. While highly attenuated for growth in normal mice, both AV1 and AV2 effected complete and durable cures in the majority of treated animals when delivered systemically.

The main objective of this study was to determine the feasibility and the antitumor activity of a chemotherapy regimen with a 48-hour infusion of 5-fluorouracil (5-FU), leucovorin (LV), cisplatin (CDDP), and epirubicin (EPIDX) administered every 3 weeks in patients with locally advanced or metastatic gastric cancer. Thirty-three patients received CDDP 60 mg/m2 over 30 minutes followed by 1-LV 250 mg/m2 over 2 hours followed by EPIDX 60 mg/m2 over 5 minutes (bolus) and followed by 5-FU 3,800 mg/m2 as a 48-hour semiintermittent continuous infusion, with 67% of total daily dose administered between 4 pm and midnight. Four patients had a locally advanced disease and 29 had metastatic disease. A total of 171 cycles were administered. Most relevant toxicities were stomatitis (grade III in 2% of cycles and 12% of patients) and neutropenia (grade III-IV in 8% of cycles and 28% of patients) with 3 (9%) patients experiencing 1 episode of febrile neutropenia. No toxic deaths occurred. Thirty-one patients were evaluable for response. In 3 patients (9.6%) a complete response and in 11 patients (35.4%) a partial response was observed, for an objective response rate of 45% (95% C.I. 27-64%). Median progression-free and overall survival were 5.9 and 9.8 months, respectively. In conclusion, this regimen is feasible in an outpatient setting with acceptable and manageable toxicities, and it is associated with promising antitumor activity, time to progression, and survival.

We report a case of right maxillary carcinoma with metastases to the cervical lymph nodes (T4N2cM0, Stage IV). A 76-year-old woman was administered preoperative chemoradiotherapy, followed by curative surgery. TS-1 (80 mg/day), CDDP (5 mg/m2/day) and concurrent radiation (total 40 Gy) induced a complete response. Grade 2 neutropenia, thrombocytopenia and stomatitis were observed. In the primary tumor and cervical metastatic lymph nodes, no viable carcinoma cells were detected and cancer nests were replaced with marked fibrous tissue.
