levoleucovorin and Ascites

Oral fluoropyrimidine plus cisplatin is a standard treatment for advanced gastric cancer, but patients with severe peritoneal metastasis often cannot tolerate this regimen. The aim of this study was to assess the feasibility of fluorouracil, l-leucovorin and paclitaxel therapy in such patients.. In the first phase of the study, we investigated the maximum tolerated dose and recommended dose in Cycle 1 of fluorouracil, l-leucovorin and paclitaxel, at two dose levels [Level 1 (n = 6): 5-fluorouracil/l-leucovorin/paclitaxel = 500/250/60 mg/m(2); Level 2 (n = 6): 600/250/80 mg/m(2) on Days 1, 8 and 15, every 28 days]. Nineteen additional patients at the recommended dose level were enrolled in the second phase to investigate the feasibility of fluorouracil, l-leucovorin and paclitaxel therapy. The primary endpoint in the second phase was the completion rate of two cycles.. Dose-limiting toxicities were observed in a patient at Level 1 with Grade 4 gastrointestinal perforation (the site of primary tumor), and in two patients at Level 2 with Grade 3 febrile neutropenia and Grade 3 infection, respectively. In Cycle 2, treatment-related death occurred at Level 2 in one patient who had Grade 4 febrile neutropenia with pneumonia. The maximum tolerated dose was set at Level 2, and the recommended dose was determined as Level 1. In the second phase, the completion rate of two cycles was 92% and the ascites response was 44%. Median progression-free survival was 4.2 months and overall survival was 8.0 months. Grade 3/4 neutropenia was observed in 12% of patients.. Fluorouracil, l-leucovorin and paclitaxel at Level 1 is feasible as first-line treatment for peritoneal disseminated gastric cancer patients with massive ascites or inadequate oral intake.

Clinical studies regarding chemotherapy for gastric cancer patients with malignant ascites have been classically rather limited in scope, largely because peritoneal seeding produces no measurable lesions, and patients generally exhibited poor performance status. Herein, we have evaluated the efficacy and toxicity of a fortnightly modified FOLFOX-4 (m-FOLFOX) regimen.. Gastric cancer patients with cytologically confirmed malignant ascites were treated with cycles of oxaliplatin at 85 mg/m(2) plus leucovorin 20 mg/m(2) on the first day of treatment, followed by 5-fluorouracil (5-FU) via a 400 mg/m(2) bolus and a 22 h continuous infusion of 600 mg/m(2) 5-FU on Days 1-2 at 2-week intervals.. Forty-eight patients participated in this study. Twenty-two patients (45.8%) were treated with m-FOLFOX-4 as a first line palliative treatment. Twenty-one patients (43.8%) were adjudged to have an Eastern Cooperative Oncology Group (ECOG) performance status of 2. Thirty-six patients were assessable and exhibited measurable lesions. Twelve (33.3%) patients evidenced partial responses. Decreases or disappearances of ascites levels were observed in 17 (35.4%) patients. The median time to progression and overall survival time were 3.5 (95% CI: 2.9-4.1) months and 8.4 (95% CI: 4.9-11.9) months, respectively. Major hematologic toxicities included Grades 1-2 anemia (53.9%), neutropenia (41.6%) and, Grades 3-4 neutropenia (15.8%). The most frequently detected non-hematological toxicities were Grades 2 and 3 nausea/vomiting (17%). We noted no deaths related to treatment.. The m-FOLFOX-4 regimen utilized herein was determined to be both safe and feasible even for gastric cancer patients with malignant ascites in poor performance status.

The efficacy of systemic chemotherapy against peritoneal dissemination from advanced gastric cancer (AGC) remains unclear, because the peritoneal dissemination was not defined as a measurable lesion in conventional phase II studies. In this study, we evaluated the efficacy and toxicity of sequential MTX and 5FU therapy (MF) in chemotherapy-naive patients with AGC accompanied by malignant ascites in a phase II setting.. The treatment schedule comprised weekly administration of MTX (100 mg/m2, i.v. bolus) followed by 5FU (600 mg/m2, i.v. bolus) with a 3 h interval. Leucovorin rescue (10 mg/m2 every 6 h, for a total of six times) was commenced 24 h after MTX administration.. Thirty-seven chemotherapy-naive patients with AGC presenting with malignant ascites were enrolled in this trial. The median age was 60 years (range, 25-74 years) and most patients (86%) had a performance status of 0-1. In total, 355 administrations of the sequential MTX/5FU therapy were performed. Major toxicity consisted of myelosuppression and gastrointestinal toxicity. Grade 4 neutropenia occurred in 10.8% of the patients. The overall objective response rate was 5.7% (two partial responses in 35 patients; 95% confidence interval: 0.7-19.2%). However, the response rate of ascites was 35.1% (complete disappearance in three patients and apparent decrease in 10 patients; 95% confidence interval: 20.2-52.5%).. Sequential MTX/5FU therapy is effective against AGC with malignant ascites with acceptable toxicity and warrants further investigations in a phase III setting.

Urachal carcinoma is a rare cancer, with limited evidence regarding systemic chemotherapy for metastatic urachal carcinoma. This study aimed to evaluate the efficacy and safety of a combination therapy of 5-fluorouracil and irinotecan (FOLFIRI) in patients with metastatic urachal carcinoma.. Patients with metastatic urachal carcinoma treated with FOLFIRI between March 2008 and April 2023 at the Department of Medical Oncology, Tohoku University Hospital, were retrospectively analyzed using medical records.. Six patients with urachal carcinoma received FOLFIRI. The histological type was adenocarcinoma in all patients. The metastatic or recurrent sites were the peritoneum, lungs, lymph nodes, and local relapse sites. Three patients received FOLFIRI as first-line chemotherapy, and the other three received FOLFIRI as second-line chemotherapy. Two patients had only non-measurable lesions as the targets of tumor response. The best response was the stable disease or non-complete response/non-progressive disease in four patients, with a disease control rate of 67%. The median progression-free survival was 7.5 months. In two patients with ascites only as the site of metastasis, the amount of ascites and serum tumor marker levels decreased after FOLFIRI was initiated. Grade 3/4 toxicities included grade 3 neutropenia in one patient and grade 3 diarrhea in one patient.. FOLFIRI has modest efficacy and good tolerability for the treatment of metastatic urachal carcinoma.

There is no standard first-line chemotherapy for advanced gastric cancer with severe peritoneal metastasis. Although fluoropyrimidine is often used, its efficacy is limited, and it remains unclear whether combination therapy with platinum improves clinical outcomes.. This retrospective study involved patients at six Japanese academic hospitals between 2010 and 2016. Patients with advanced gastric cancer and severe peritoneal metastasis were included if they had massive ascites and/or inadequate oral intake requiring intravenous nutritional support. We then compared the efficacy and safety of fluoropyrimidine monotherapy with those of fluoropyrimidine/platinum combination therapy.. Compared with the combination therapy group (n = 64), the monotherapy group (n = 65) had worse general health (more patients with elderly age, performance status > 2, and having both massive ascites and inadequate oral intake). Both overall survival (9.0 vs 5.0 months, p < 0.01) and progression-free survival (4.3 vs 2.3 months, p < 0.01) were significantly longer in the combination group, and the significance remained after adjusting for prognostic variables (hazard ratios of 0.47 and 0.41, respectively; p < 0.01). Improvements in ascites and oral intake were also greater in the combination group. Although neutropenia (grade ≥ 3) occurred more frequently with combination therapy, both treatments in this study were tolerable.. Combination therapy with fluoropyrimidine and platinum might be more effective than monotherapy with fluoropyrimidine and was tolerable for patients with advanced gastric cancer and severe peritoneal metastasis.

Pseudomyxoma peritonei is a disease that results from a perforated mucinous neoplasm of the appendix so that mucinous ascites and mucin-producing tumor cells are widely disseminated in a characteristic pattern throughout the abdomen and pelvis. The intraabdominal mucus can accumulate in the inguinal canal and by physical examination be indistinguishable from the usual inguinal hernia.. A database of patients with pseudomyxoma peritonei was used to identify patients who had an inguinal hernia prior to or at the time of cytoreductive surgery (CRS) and perioperative hyperthermic chemotherapy (HIPEC). At the time of CRS, care was taken in all patients to remove the peritoneal lining of the inguinal canal. Patients who had the inguinal hernia repaired prior to definitive treatment with CRS and HIPEC had all tissue and mesh associated with prior herniorrhaphy resected.. In 178 pseudomyxoma peritonei patients, 17 had a new onset or previously repaired inguinal hernia that required extraction of mucus and mucinous tumor from the hernia site. No repair of the open inguinal canal was attempted at the time of CRS. No recurrent inguinal hernias were recorded and no patients required an inguinal incision at a later time to resect progressive disease within the inguinal canal.. Inguinal hernias caused by mucinous ascites and tumor were definitively treated by cytoreductive surgery plus HIPEC. Extraction of tumor and peritoneum from the inguinal canal facilitates fibrous closure of the hernia defect so that hernia recurrence was not observed.

Advanced gastric cancer patients with malignant ascites cannot tolerate S-1 plus cisplatin-containing therapy. The good toxicity profile of the FLTAX regimen(5-fluorouracil[5-FU]and Leucovorin[l-LV]combined with weekly paclitaxel) might make it a viable alternative treatment for these patients. We retrospectively evaluated the efficacy and safety of FLTAX in advanced gastric cancer patients.. Patients with advanced gastric cancer with malignant ascites were treated with 60mg/m2 paclitaxel, followed by 500 mg/m2 5-FU and 250 mg/m2 l-LV on days 1, 8, and 15. Treatment courses were repeated every 28 days. Patients were treated in our hospital from 2014 to 2016.. Three advanced gastric cancer patients with malignant ascites received the FLTAX regimen. The median age was 66 years(range 58-66). The median number of treatment courses was 2(range 1-20). The median progression-free survival and overall survival were 55(95%CI 24-.)and 272(95%CI 108-.)days, respectively. Observed Grade 3-4 adverse events were as follows: hyponatremia(1), anorexia(1), upper gastrointestinal hemorrhage(1), and thromboembolic event(1). No treatment-related death occurred.. FLTAX demonstrated an acceptable toxicity profile, and may be a good option for gastric cancer patients with malignant ascites.

The pharmacokinetics of oxaliplatin in plasma and ascitic fluid was investigated in 5 gastrointestinal cancer patients with malignant ascites. Oxaliplatin was administered at 85 mg/m² by 2-hour infusion in the FOLFOX4 regimen, and the concentrations of total and free platinum were measured. There was a trend of lower plasma C(max) values of total platinum in patients with a larger volume of ascitic fluid. The AUC(0-t) values of mean concentration curves of total plasma platinum, total ascites platinum, free plasma platinum, and free ascites platinum were 31.15, 7.96, 4.93 and 2.93 mg•h/ml, respectively. The concentrations of free ascites platinum were similar to those of free plasma platinum at the last sampling time of 26 h in each patient. The decrease or disappearance of ascitic fluid was observed in 4 patients. These results suggest that oxaliplatin exerted a beneficial effect in gastrointestinal cancer patients with malignant ascites, even when administered intravenously.

We have previously reported that 24-h intra-arterial combination chemotherapy (IACC) prolongs the survival of patients with advanced hepatocellular carcinoma (aHCC). However, it has also been reported that 5-fluorouracil (5-FU) exacerbates liver damage in patients with liver cirrhosis (LC). The aim of this study was to clarify the hepatotoxicity of IACC in LC patients with aHCC.. Twenty-one adult Japanese patients (20 men and 1 woman) with aHCC and LC underwent IACC between 2004 and 2007 at our hospital. These patients showed multiple partial responses or stable disease, except for five patients who showed no response and three patients with tumors more than 30 mm in diameter. All patients had inoperable disease on the basis of computed tomography (CT) findings. IACC (leucovorin at 12 mg/h, cisplatin at 10 mg/h, and 5-FU at 250 mg/22 h) was delivered via the proper hepatic artery every 5 days for 4 weeks.. Twelve patients were in Child-Pugh class A (group A), and nine were in class B (group B). The Child-Pugh score was significantly increased after chemotherapy compared with before chemotherapy in both groups. Serum albumin was significantly decreased after chemotherapy, and the number of patients with ascites also increased after chemotherapy. Serum type IV collagen and N-terminal propeptide of type III procollagen were significantly increased after chemotherapy, although there was no significant change in serum aminotransferases.. IACC might cause hepatotoxicity that induces fibrosis without releasing aminotransferases.

Although peritoneal dissemination of gastric cancer is common and often causes deterioration of the patient's condition and quality of life (QOL), these patients are usually excluded from clinical trials. We retrospectively investigated the clinical benefit and toxicity of sequential methotrexate and 5-fluorouracil (MTX/5FU) therapy for patients with peritoneal dissemination.. The subjects were 31 patients with severe peritoneal dissemination of gastric cancer who were treated with MTX/5FU. The treatment schedule comprised weekly administration of MTX (100 mg/m(2)) followed by 5FU (600 mg/m(2)). Leucovorin (10 mg/m(2)) was administered six times, every 6 h, starting 24 h after MTX administration.. The median survival time was 255 days, and the median progression-free survival was 127 days. Of the 21 patients with measurable lesions, 4 (19%) patients achieved a partial response. Ascites volume decreased markedly in 14 (54%) of the 26 patients with ascites. Seventeen patients had adequate oral intake, but the other 14 patients had required nutritional support before treatment. The median dripinfusion free survival was 100 days in the former 17 patients, and oral intake improved in 3 (21%) of the latter 14 patients. Grade 3 or 4 neutropenia was observed in 26% of the patients and anemia was observed in 45%. The grade 3 nonhematological toxicities were vomiting (6%) and fatigue (10%). Early death, within 30 days of the last administration of MTX/5FU, occurred due to disease progression in 2 patients, but there were no treatment-related deaths.. MTX/5FU chemotherapy may be effective in treating peritoneal dissemination of gastric cancer and might improve the patient's condition in terms of reducing ascites and improving oral intake.

We performed combination therapy with oxaliplatin/l-LV/5-FU (FOLFOX 4) in a patient with recurrent colorectal cancer (a 58-year-old man) who had pleural effusion and ascites. This resulted in disappearance of the pleural effusion and ascites, as well as negative tumor markers. Surgery was performed for sigmoid colon cancer on September 29, 2004. In February 2006, abdominal swelling was observed, and CEA increased to 15 ng/mL with multiple intraabdominal tumor nodules. The patient was diagnosed as having peritonitis carcinomatosis associated with recurrent sigmoid colon cancer, and was treated with FOLFOX 4. CEA was 134.9 ng/mL before treatment, but became negative after six courses, while his pleural effusion and ascites disappeared after 10 courses of treatment. This treatment also appeared to be useful for recurrent colorectal cancer with peritoneal dissemination.

We report a case in which weekly paclitaxel (TXL) administration was effective for gastric cancer with malignant ascites. TXL (80 mg/m2) was infused over 1 hour after short premedication on an outpatient basis. Administration was continued for 3 weeks followed by 1 week rest. The patient was a 49-year-old woman who suffered from non-resectable gastric cancer, staged intraoperatively as having severe lymph node metastasis and malignant ascites. As an outpatient treatment, she was first treated with 5-fluorouracil combined with high-dose Leucovorin for 4 cycles. However, she complained of abdominal fullness and ascites, and received weekly TXL administration as the second line treatment. The ascites had completely disappeared 3 months after administration. The toxic events were anemia (grade 1) and alopecia (grade 2). No major adverse effects such as hypersensitivity reaction, leukopenia or peripheral neuropathy were observed.

The therapeutic effect of antibodies raised by the immunogen Gastrimmune was compared with both a CCKB/gastrin receptor antagonist, CI-988, and 5-Fluorouracil/leucovorin in a gastric cancer model. The human gastric ascites cell line, MGLVA1asc, produced and secreted progastrin and glycine-extended gastrin as determined by radioimmunoassay and immunocytochemistry. Cells were also stained with an antiserum directed against the human CCKB/gastrin receptor. MGLVAI asc cells were injected i.p. into SCID mice. Antibodies raised by Gastrimmune immunization of rabbits (affinity for G17 of 0.15 nM and GlyG17 of 0.47 nM) were passively infused i.p. and significantly enhanced survival by up to 5 days (p=0.0024 from vehicle controls). The enhancement in survival was not significantly different from that achieved by treatment with 5-Fluorouracil and leucovorin. A CCKB/gastrin receptor antagonist, CI-988, did not affect survival with cells injected at 7.5 x 10(5) cells/mouse but significantly increased the survival of mice injected with a lower cell innoculum of 5 x 10(5) cells/mouse from 30 to 35 days (p=0.0186). At this lower innoculum antibodies raised by Gastrimmune induced complete survival in 2 animals with the remaining dead by day 36 (p=0.0022). Thus, both endocrine and autocrine pathways mediated by precursor and mature gastrin molecules may be jointly operational in the gastric cancer scenario and may be important targets for therapeutic agents.

We investigated the pharmacokinetics of tetrahydrofolates following the administration of [6S,R]-folinic acid and 5-flurouracil delivered i.v., i.p., and by a combination of both routes in patients with colon cancer. The concentrations of the biologically active tetrahydrofolates ([6S]-folinic acid and 5-methyltetrahydrofolate) and the relatively inert diastereomer [6R]-folinic acid were monitored using a selective on-line coupled achiral-chiral high-performance liquid chromatographic method. In plasma, a target concentration of 5 microM active tetrahydrofolates, which is considered necessary for an optimal synergistic effect, could be achieved after i.v. or combined i.v. and i.p. administration but was not reached in a patient receiving i.p. [6S,R]-folinic acid alone. In three patients receiving i.p. [6S,R]-folinic acid a high level of [6S]-folinic acid was observed in ascites, suggesting that the peritoneal cavity may act as a storage site for tetrahydrofolates after i.p. administration. In these patients, only a trace level of the active metabolite 5-methyltetrahydrofolate was detected in ascites, which may indicate that tetrahydrofolate derivatives penetrate only minimally, if at all, into the peritoneal cavity from the central compartment. These data would indicate that a combination of i.p. and i.v. administration may, from the pharmacological point of view, indeed contribute to an improved treatment of minimal residual disease persisting in the peritoneal cavity.
