Two cases of advanced gastric cancer effectively treated with chemotherapy of 5-fluorouracil, cisplatin and cytarabine

We reported two cases of advanced gastric cancer effectively treated with chemotherapy of 5-fluorouracil (5-FU), cisplatin (CDDP) and cytarabine (Ara-C), 5-FU (300-350 mg/body) was given by continuous intravenous infusion. Ara-C (20-40 mg/body) by continuous infusion and CDDP (15-20 mg/body) were added intravenously for 3-6 days. For case 1, epirubicin (30 mg/body) was also given on the first day of each therapy course. Case 1 was a 62-year-old female who had gastric cancer with liver metastasis, ovarian metastasis and peritonitis carcinomatosa. After 3 courses of the chemotherapy, reduction of ovarian metastasis greater than 75% was observed. The value of CA125 decreased from 6,800 U/ml to 527 U/ml and ascites disappeared. Case 2 was a 54-year-old male who had type 3 advanced gastric cancer with multiple liver metastases. He received 6 courses of the therapy. Both primary and metastatic tumors showed over 50% reduction in tumor size. These suggested that this combination therapy was effective for inoperable advanced gastric cancers.     

A case of advanced primary ureteral squamous cell carcinoma responding to combination chemotherapy with cisplatin and 5-fluorouracil

A 63-year-old female with left ureteral tumor metastasizing to the left iliac lymph node was treated with left total nephroureterectomy. The histopathological diagnosis was squamous cell carcinoma of the ureter, G1 INF beta, pT2, pR0, pV1 and pL0. Three cycles of chemotherapy were performed postoperatively with cis platin and 5-fluorouracil. A major response was obtained (tumor regression rate, 57%). She received 60 Gy radiotherapy to the left iliac region postchemotherapy (postradiotherapy tumor regression rate, 74%). No evidence of the tumor relapse was found 7 months after irradiation.     

A randomized phase-II study of BB-10010 (macrophage inflammatory protein- 1alpha) in patients with advanced breast cancer receiving 5-fluorouracil, adriamycin, and cyclophosphamide chemotherapy

BB-10010 is a variant of the human form of macrophage inflammatory protein-1alpha (MIP-1alpha), which has been shown in mice to block the entry of hematopoietic stem cells into S-phase and to increase their self-renewal capacity during recovery from cytotoxic damage. Its use may constitute a novel approach for protecting the quality of the stem cell population and its capacity to regenerate after periods of cytotoxic treatment. Thirty patients with locally advanced or metastatic breast cancer were entered into the first randomized, parallel group controlled phase II study. This was designed to evaluate the potential myeloprotective effects of a 7-day regimen of BB-10010 administered to patients receiving six cycles of 5-fluorouracil (5-FU), adriamycin, and cyclophosphamide (FAC) chemotherapy. Patients were randomized, 10 receiving 100 microgram/kg BB-10010, 11 receiving 30 microgram/kg BB-10010, and nine control patients receiving no BB-10010. BB-10010 was well-tolerated in all patients with no severe adverse events related to the drug. Episodes of febrile neutropenia complicated only 4% of the treatment cycles and there was no difference in incidence between the treated and nontreated groups. Studies to assess the generation of progenitor cells in long-term bone marrow cultures were performed immediately preceding chemotherapy and at the end of six dosing cycles in 18 patients. Circulating neutrophils, platelets, CD 34(+) cells, and granulocyte/macrophage colony-forming cell (GM-CFC) levels were determined at serial time points in cycles 1, 3, and 6. The results showed similar hemoglobin and platelet kinetics in all three groups. On completion of the six treatment cycles, the average pretreatment neutrophil levels were reduced from 5.3 to 1.7 x 10(9)/L in the control patients and from 4.3 to 1.9 and 4.5 to 2.5 x 10(9)/L in the 30/100 microgram/kg BB-10010 groups, respectively. Relative to their pretreatment values, 50% of the patients receiving BB-10010 completed the treatment with neutrophil values significantly higher than any of the controls (P = .02). Mobilization of GM-CFC was enhanced by BB-10010 with an additional fivefold increase over that generated by chemotherapy alone, giving a maximal 25-fold increase over pretreatment values. Bone marrow progenitor assays before and after this standard regimen of chemotherapy indicated little long-term cumulative impairment to recovery from chemotherapy. Despite the limited cumulative damage to the bone marrow, which may have minimized the protective value of BB-10010 during this regimen of chemotherapy, better recovery of neutrophils in the later treatment cycles with BB-10010 was indicated in a number of patients.     

Clinical results of combination chemotherapy with cisplatin, vinblastine and bleomycin (pvb) for advanced testicular cancer: evaluation of risk criteria

Between 1982 and 1991, 24 patients with advanced testicular germ cell tumor were treated by combination chemotherapy with cisplatin, vinblastine and bleomycin (PVB). Based on short-term efficacy of the PVB regimen and long-term prognosis in our patients, we evaluated 4 risk criteria proposed by Indiana University, National Cancer Institute (NCI), Memorial Sloan-Kettering Cancer Center (MSKCC) and European Organization for Research and Treatment of Cancer (EORTC). Clinical staging were IIA in 8 patients, IIB in 8, IIIA in 1, IIIB in 5 and IIIC in 2. Metastases included retroperitoneal lymph node in 20 cases (> 5 cm in 10), lung in 6, bone and liver in each 1. Complete response (CR) was obtained in 12 (50%) patients and partial response (PR) in 9 (38%). According to the stage and metastatic site, CR was achieved in 75%, 38% and 38%of the stage IIA, IIB and III tumors, respectively, and in 60% and 50% of retroperitoneal and pulmonary metastases, respectively. However, neither CR nor PR was recognized for live and bone metastases. Prognosis was assessed with a mean followup period of 88.5 months. Although all 12 patients with CR were alive, 4 of the 9 with PR and all patients on whom the drug was ineffective died of cancer. Accuracy in predicting prognosis was 82%, 75%, 74%, and 63% using the MSKCC, Indiana, NCI and EORTC risk criteria, respectively.     

Effect of CDDP/5'-DFUR combination chemotherapy for advanced or recurrent gastric cancer

CDDP/5'-DFUR combination chemotherapy was performed on 17 patients with non-resected and recurrent gastric cancer (clinical stage were IVb in all patients). They were treated with 1,400 mg/m2 of 5'-DFUR on days 1-4 orally following by withdrawal 10 days, every 2 weeks repeatedly and 80 mg/m2 of CDDP (c. i. v., on day 5, every 4 weeks). This chemotherapy was performed for at least 2 courses on all patients. Eight of 17 patients achieved a partial response and the overall response rate was 47.1% (differentiated type 57.1%, undifferentiated type 45.5%). Response rates of each lesion were as follows: primary foci 42.9%, abdominal lymph nodes 57.1%, hepatic metastasis 60.0% and ascites 33.3%, respectively. Improvement of performance status was seen in 12 of 17 patients (70.6%). The overall median survival time was 227 days. The median outpatient period was 113 days. There was no high-grade toxicity over grade 2. Therapeutic toxicity of grade 2 was manifested as renal dysfunction (23.5%), nausea/vomiting (17.6%), leukopenia (5.9%) and anemia (5.9%). We evaluated the therapeutic effect by visual examination after completion of the second course. However, poor effect and high incidence of renal dysfunction were found in patients treated with this therapy over four times. Therefore, the maximum effect seemed to be revealed after completion of the fourth course. From the present study, CDDP/5'-DFUR combination chemotherapy seems to be effective for patients with high-grade advanced gastric cancer and improved their quality of life.     

Retrospective comparison of infusional 5-fluorouracil, doxorubicin, and mitomycin-C (modified FAM) combination chemotherapy versus palliative therapy in treatment of advanced gastric cancer

About one-third of patients with gastric cancer are unresectable at the time of diagnosis. Their median survival is < 6 months, with a grave prognosis. The purpose of this study was to assess the efficacy of a modified FAM (mFAM) regimen in advanced gastric cancer. We retrospectively reviewed the clinical records of 409 advanced gastric cancer patients who had not received curative surgery. Among 409 patients, 202 patients were treated with an mFAM regimen (infusional 5-FU + doxorubocin + mitomycin-C), and 207 patients received no chemotherapy (control group). No differences were found in clinical parameters between the two groups. The 1-year survival rates were 34.1% for the mFAM-treated group and 22.5% for the control group (p = 0.0135). In subset analysis, a higher 1-year survival rate was demonstrated in patients with mFAM and palliative surgery. Of the 154 evaluable patients in the mFAM-treated group, the response rate was 17.5%. In these patients, median response duration was 30 weeks, and progression-free survival was 23 weeks. Overall toxicity of mFAM regimen was relatively tolerable and reversible. In conclusion, FAM combination chemotherapy, which has been used as a standard therapy, prolonged survival after modification of the administration schedule and combination with palliative surgery. A prospective randomized study is warranted to confirm this conclusion from our retrospective study.     

Treatment of advanced colorectal cancer with folinic acid and 5-fluorouracil in combination with cisplatinum

51 patients with metastatic colorectal cancer (stage Dukes D) were treated with intravenous (i.v.) infusion on days 1, 3, 5, 8 and 16 with folinic acid (200 mg/m2) and 5-fluorouracil (600 mg/m2), and on days 1, 8 and 16 with cisplatinum (25 mg/m2 i.v.); cycles were repeated every 4 weeks. All 51 patients were evaluable for toxicity and response criteria. 26 patients had objective responses (3 complete responses, 5.9%; 23 partial responses, 45.1%), relative risk 51% (95% confidence intervals 36.7-65.0%). Response duration ranged from 4 to 28.0 months (median 16.8). Overall median survival of all patients included was 14.7 months (range 3.0-33.0). Toxicity of WHO grade III, requiring dose reduction, occurred in 9 (18%) patients. The regimen described here appears to be active, safe and well tolerated for treatment of patients with advanced colorectal cancer.     

Combination chemotherapy with Tegafur. Uracil (UFT), etoposide, adriamycin and cisplatinum (UFT-EAP) for advanced gastric cancer

Thirty-four patients with advanced gastric cancer were treated with combination chemotherapy employing Tegafur-Uracil (UFT), etoposide, Adriamycin, and Cisplatinum (CDDP) (UFT-EAP therapy). An objective partial response was obtained in 16 patients (47%) and the median duration of remission was 12.2 months. The 50% survival time for all 34 patients was 10 months. Patients with moderately or well differentiated adenocarcinoma responded well (13/19, 68%), while those with undifferentiated adenocarcinoma showed a poor response (3/15, 20%). Six responding patients were noted to have no evidence of viable cancer at the primary site by endoscopic biopsy, and underwent gastrectomies. The resected specimens showed complete disappearances of the primary tumors in four patients. The median survival time for the patients receiving gastrectomies was 24 months. The regimen was very well tolerated, apart from moderate bone marrow suppression. Our results suggest that patients with advanced gastric cancer can be effectively treated with UFT-EAP chemotherapy.     

A phase II study of 5-fluorouracil, leucovorin and cisplatin (FLP) for metastatic gastric cancer

The modulation of 5-fluorouracil (5-FU) with folinic acid (leucovorin, LV) is more efficacious than 5-FU alone in the treatment of metastatic colorectal cancer, and the combination of 5-FU with cisplatin is currently one of the most active regimens in advanced gastric cancer. A phase II study was therefore conducted to test the efficacy and toxicity of the combination of 5-FU, LV and cisplatin (FLP) in metastatic gastric cancer. 28 patients entered the study. Metastatic sites were observed in the liver (in 21 patients), the peritoneum (in 8), the lymph nodes (in 7) or the bones (in 1) and a local recurrence was noted in 4 cases. The performance status (using World Health Organisation criteria) was 0 for 13 patients and 1 or 2 for the others. Cycles of treatment were administered every 28 days and consisted of LV 200 mg/m2/day for 5 days followed by 5-FU 400 mg/m2/day for 5 days with cisplatin 100 mg/m2 on day 2. The response rate for the 27 evaluable patients was 51.8% (95% confidence interval (CI), 33-70.6%). There were four complete responses (14.8%) and 10 partial responses (37%). Median survival was 11 months and 4 patients were alive at 2 years. Both response rate and survival were better for patients with a good performance status. The overall toxicity was very low, except for 1 patient who died of dehydration and cardiac failure. In conclusion, the FLP protocol was effective and well tolerated in patients with metastatic gastric cancer.     

Combination chemotherapy of continuous infusion 5-fluorouracil and daily low-dose cisplatin in advanced gastrointestinal and lung adenocarcinoma

Continuous intravenous infusion (c.v.i.) of 5-fluorouracil (5-FU) plus daily low-dose cisplatin (CDDP) was evaluated in 45 patients with advanced and recurrent unresected colorectal, lung, gastric and pancreatic adenocarcinoma. 5-FU was given at a dose of 320 mg/m2/day, c.v.i. for 4 weeks, and CDDP between 3.5 to 7 mg/m2/day, infused for one hour five times a week for 4 weeks. Patients received 1 to 3 cycles of treatment (average 1.5 cycle). Pancreatic cancer cases needed longer treatment periods (2.25 cycles). The response rate of colorectal cancer cases was 57.7% (15/26), pancreas cancer 40%, gastric cancer 62.5%, and lung cancer 66.7%. The overall response rate was 57.8%. No severe side effects occurred in any of these cases. These data indicate that this combination 5-FU + daily low-dose CDDP chemotherapy is effective in the treatment of advanced gastrointestinal and lung adenocarcinoma.     

5-Fluorouracil, folinic acid, etoposide and cisplatin chemotherapy for locally advanced or metastatic carcinoma of the oesophagus

38 patients with advanced oesophageal carcinoma were treated with intravenous (i.v.) folinic acid (300 mg/m2), 5-fluorouracil (500 mg/m2), etoposide (100 mg/m2), and cisplatin (30 mg/m2) (FLEP), on days 1, 2 and 3, every 22-28 days. 26 patients had locally advanced disease (LAD) and 12 had metastatic disease (M1). Oesophagectomy was planned for patients with LAD in case of tumour regression after chemotherapy, while patients with M1 disease received chemotherapy only. The overall remission rate was 45% (17/38) including four clinical and two pathologically confirmed complete remissions. 16 patients underwent oesophagectomy, 12 after response to FLEP, and 4 after FLEP and subsequent irradiation +/- 5-fluorouracil/mitomycin. Toxicity was mainly haematological, with WHO grade 3 and 4 leukocytopenia in 50% and thrombocytopenia in 31% of the patients. Two treatment-related deaths were observed; one due to chemotherapy and one postoperatively. Median survival time of LAD patients was 13 months, and actuarial 2-year survival was 31%. Patients with complete tumour resection after FLEP had a median survival time of 18 months and a 2-year survival rate of 42%. Median survival of M1 patients was 6 months. FLEP is an active combination for oesophageal cancer, especially when used preoperatively in LAD.     

Randomized prospective trial comparing 5-fluorouracil (NSC-19893) to 5-fluorouracil and methyl-CCNU (NSC-95441) in advanced gastrointestinal cancer

The Southwest Oncology Group has confirmed the superiority of 5-fluorouracil (5-FU) and methyl-CCNU versus 5-FU weekly as treatment for patients with advanced gastrointestinal cancers. The drug combination produced a PR rate of 29.3% compared to the single-drug arm rate of 10.6%; however, the two-drug arm produced much more toxicity. Despite the improved response rate no improvement in survival was observed.     

First-line chemotherapy for advanced ovarian cancer: paclitaxel, cisplatin and the evidence

As of June 1998, four randomized trials have been completed comparing the combination of paclitaxel and cisplatin with a cisplatin-based control arm. The results of three of these trials are available; one has been published as a full paper, the other two in abstract form only. Two of the reported trials (GOG-111 and the Intergroup trial) provide clear evidence that cisplatin combined with paclitaxel is a more effective regimen than one using the same dose of cisplatin combined with cyclophosphamide. The results of the third reported trial (GOG-132) are rather different, suggesting that a higher dose of single-agent cisplatin may be as effective as the paclitaxel/cisplatin combination tested in the other two trials. A number of explanations for these unexpected results have been proposed: false-positive results in GOG-111 and the Intergroup trial; false-negative results in GOG-132; high crossover in GOG-132 (including crossover before progression); the cyclophosphamide in the control arm of GOG-111 and the Intergroup trial had a negative impact on outcome in the control group in these trials; the higher dose of cisplatin when used as a single agent in GOG-132 had a positive impact on outcome for the control group in this trial. These explanations are discussed in detail, and their implications explored.     

Oxaliplatin, folinic acid and 5-fluorouracil (folfox) in pretreated patients with metastatic advanced cancer. The GERCOD

Preliminary studies suggest synergy between oxaliplatin and fluorouracil (5-FU). To assess this issue, we performed a study in pretreated patients with advanced colorectal cancer (CRC) resistant to leucovorin and 5-FU. Regimen consisted of oxaliplatin day 1, 130 mg/m2 every two cycles (folfox 1) or 100 mg/m2/cycle (folfox 2) or 85 mg/m2/cycle (folfox 3) and leucovorin 500 mg/m2 as a 2-hour infusion, followed by 5-FU 22 h infusion 1.5-2 g/m2 for two consecutive days every 2 weeks. One hundred and thirteen patients have been treated. One complete response (CR) and 32 partial responses (PRs) were observed for an overall response rate of 29.2%. Sixty-seven patients had prior documented progression while receiving the same schedule of leucovorin and 5-FU than the one used in the folfox regimens, among them 18 had PRs (26.9%). The best response rate was observed in patients treated with the folfox 2 regimen: 41.7%. From start of folfox, median progression-free survival was 6 months and median survival 13 months. Limiting toxicities were peripheral neuropathy and neutropenia. Fifty-four percent of the patients experienced WHO toxicity > or = grade 3 with the folfox1 regimen, 45% with the folfox2 and 40% with the folfox3. The folfox regimens achieve a high response rate in pretreated patients with CRC. Further studies are needed to determine the best oxaliplatin dose-intensity.     

Phase I and pharmacologic study of irinotecan in combination with cisplatin for advanced lung cancer

Macroscopic T-type Ca2+ currents, which are often observed in fetal and neonatal cardiac muscle cells, were not found in normal (0 of 17) adult feline ventricular myocytes. However, they were present in most (15 of 21) myocytes isolated from adult feline left ventricles with long-standing pressure-overload-induced hypertrophy. This is the first study to provide evidence in a large mammal, such as the cat, that T-type Ca2+ channels may be reexpressed in adults in association with hypertrophy resulting from slow progressive pressure overload. Importantly, this expression was stable for the duration of the hypertrophy process and was not associated with abrupt pressure overload. T-type Ca2+ currents were separated from L-type Ca2+ currents by exploiting the differences in their voltage dependence of steady-state inactivation. Depolarizations from -80 mV revealed a rapidly activating inward current that peaked in magnitude at -30 mV (-1.8 +/- 0.9 [mean +/- SD] pA/pF) and fully inactivated within 100 milliseconds in 15 of 21 hypertrophied myocytes studied. Further depolarizations activated progressively less T-type Ca2+ current, so that at +10 mV the L-type Ca2+ current predominated. In the hypertrophied myocytes that demonstrated both T-type and L-type Ca2+ currents, two distinct peaks occurred in their current-voltage relations. T-type Ca2+ currents were not evident in any of the 17 normal adult feline left ventricular myocytes studied. The purpose of T-type Ca2+ currents in hypertrophy is unclear. However, their presence may make hypertrophied myocardium more prone to spontaneous action potentials and increase the likelihood for arrhythmias in partially depolarized hypertrophied myocardium.     

Successful treatment of recurrent multiple lung metastasis from colon cancer with combination chemotherapy using methotrexate, 5-fluorouracil, and high-dose leucovorin: a case report

A 66-year-old man, who had received sigmoidectomy for sigmoid cancer in 1985, was diagnosed as having multiple lung and liver tumors in September 1988. When celiac-angiography was performed, recurrent liver metastases from sigmoid cancer were suspected and he received a transarterial embolism with ADM 30 mg and MMC 20 mg. In addition, he was treated with a sequential chemotherapy with methotrexate (MTX), 1,200 mg intravenously (6 h-infusion) followed by 5-fluorouracil (5-FU), 600 mg/m2/day and leucovorin, 300 mg/body/day in continuous infusion for 5 days from day 2 with concomitant oral administration of dipyridamole (300 mg/day) over 14 days. Treatment was repeated every 28 days for two courses. For the third course, administration of only 5-FU, leucovorin and dipyridamole was performed. As a result, the size of pulmonary lesions was prominently reduced on computed tomography. Although mucositis, anal erosion, diarrhea and thrombocytopenia were noted, no severe side effects were observed. This sequential chemotherapy appears useful for metastatic lesions from colon cancer.     

A cooperative study on concomitant with low-dose divided administration of cisplatin (CDDP) and sustained drip infusion of 5-fluorouracil (5-FU) for unresectable advanced gastric cancer. Osaka Cisplatin Gastric Cancer Study Group

British Indian Asian men aged <40 years have a twofold to threefold increased risk of death from coronary heart disease (CHD) compared with British whites. Epidemiological studies have suggested an association between glucose intolerance and hyperinsulinemia with premature CHD in Indian Asians. We tested the association of insulin action with myocardial infarction (MI) by using the hyperinsulinemic-euglycemic clamp in 17 MI patients: 8 Punjabi Sikhs (PSMIs), 9 British whites (BWMIs), and 17 control subjects (9 PSCs and 8 BWCs). Metabolic factors associated with insulin resistance were investigated in 51 MI patients (24 PSMIs and 27 BWMIs) and 53 control subjects (28 PSCs and 25 BWCs). Familial aggregation of defective insulin action was examined by studying five pedigrees of Sikh survivors of MI. Sikh survivors of premature MI demonstrated impaired insulin-mediated glucose uptake (P<.001) by use of the clamp technique and nonesterified fatty acid (NEFA) suppression (P<.05) by using both clamp techniques and the oral glucose tolerance test, as compared with Sikh control subjects. White patients had impaired insulin-mediated glucose uptake but normal NEFA suppression. Metabolic factors usually associated with insulin resistance, including increased 2-hour post-oral glucose tolerance test triglycerides, smaller low density lipoprotein particle size, and increased plasminogen activator inhibitor-1, were present in white (all P<.05) but surprisingly absent in Sikh (all P>.05) MI patients compared with respective ethnic control subjects. Fasting glucose and total cholesterol levels did not differ between patients and control subjects. Abdominal obesity, impaired NEFA suppression after oral glucose, and fasting hyperinsulinemia were present in Sikh MI patients and their nondiabetic first-degree relatives compared with Sikh control subjects. PS survivors of premature MI demonstrated impaired insulin-mediated glucose disposal and NEFA suppression compared with ethnic control subjects. BWMI patients showed abnormalities of carbohydrate, but not of NEFA, metabolism compared with white control subjects. Defects of insulin action manifested as abdominal obesity, impaired NEFA suppression, and fasting hyperinsulinemia are present in Sikh MI patients and their asymptomatic, nondiabetic, first-degree relatives. We suggest that these defects may be early metabolic markers that predict risk of premature MI among PSs.
