1/14. Oxaliplatin-induced fever and release of IL-6.BACKGROUND: Oxaliplatin is a novel cytotoxic agent with documented activity in colorectal cancer. Side effects are generally moderate, and include peripheral neuropathy along with mild bone marrow suppression and gastrointestinal side effects. To our knowledge, induction of febrile episodes by this agents has not been described in the literature. CASE REPORT: We present the case of a 74-year-old male patient admitted to our institution for palliative treatment of metastatic colorectal carcinoma. Due to progression during treatment with 5-fluorouracil and leucovorin, chemotherapy consisting of oxaliplatin 85 mg/m(2) on days 1 15 plus mitomycin C 8 mg/m(2) on day 1 repeated every 28 days was initiated. The first cycle of this combination was tolerated without side effects, but the patient experienced fever up to 39 degrees C starting 2 h after oxaliplatin administration on day 15 of the second cycle, which persisted for 3 days. fever again recurred at the same interval following administration of oxaliplatin on day 1 of the next cycle. blood samples taken at regular intervals disclosed an increase in IL-6 serum levels parallel to the body temperature curve, with the peak corresponding to the highest temperature, while c-reactive protein values remained unchanged. In spite of intensive premedication with steroids, antipyretics and clarithromycin, fever promptly recurred during the third cycle of treatment. CONCLUSION: Our data suggest a clear- cut correlation between fever, the release of IL-6 and oxaliplatin administration. Whether IL-6 release is directly triggered by the application of oxaliplatin or is a bystander phenomenon, however, remains unclear at the moment.- - - - - - - - - - ranking = 1keywords = cycle (Clic here for more details about this article) |
2/14. Irinotecan and thalidomide in metastatic colorectal cancer.Fifteen patients with metastatic colorectal cancer were treated with irinotecan (CPT-11, Camptosar) at 300 to 350 mg/m2 every 21 days and thalidomide (Thalomid) at 400 mg/d. Of the 15 patients, 11 were in a pilot study and 4 were in an ongoing phase II protocol. There were 12 men and 3 women, with a median age of 56 years (range: 29 to 79 years). patients were treated with a median of three cycles (range: one to eight cycles). The four patients enrolled in the formal protocol were not evaluable for response at the time of this report. Of the 11 patients in the pilot study, 10 were evaluable for response; there were two complete responses, two partial responses, and six progressions. Investigators noted a remarkable absence of grade 3/4 gastrointestinal toxicities, and concluded that further testing of the complete response and toxicity profile of the irinotecan/thalidomide regimen was warranted.- - - - - - - - - - ranking = 0.5keywords = cycle (Clic here for more details about this article) |
3/14. Extrahepatic biliary stenoses after hepatic arterial infusion (HAI) of floxuridine (FUdR) for liver metastases from colorectal cancer.Hepatic arterial infusion of floxuridine is an effective treatment for unresectable hepatic metastases from colorectal cancer. Despite its pharmacological advantage of higher tumor drug concentration with minimal systemic toxicity, hepatic arterial infusion of floxuridine is characterized by regional toxicity, including hepatobiliary damage resembling idiopathic sclerosing cholangitis (5-29% of treated cases). Unlike previous reports describing biliary damage of both intrahepatic and extrahepatic ducts, a case series of extrahepatic biliary stenosis after hepatic arterial infusion with floxuridine is herein described. Between September 1993 and February 1999, 54 patients received intraarterial hepatic chemotherapy based on continuous infusion of floxuridine (dose escalation 0.15-0.30 mg/kg/day for 14 days every 28 days) plus dexamethasone 28 mg. Twenty-seven patients underwent laparotomy to implant the catheter into the hepatic artery, the other 27 patients receiving a percutaneous catheter into the hepatic artery through a transaxillary access. Five patients (9.2%) developed biliary toxicity with jaundice and cholangitis (3 cases), alterations of liver function tests and radiological features of biliary tract abnormalities. They received from 9 to 19 cycles (mean 14.5 /- 6.3 cycles) of floxuridine infusion with a total drug delivered dose ranging from 20.3 to 41.02 mg/kg (mean: 31.4 /- 13.5 mg/kg). Extrahepatic biliary sclerosis was discovered by computed tomography scan and ultrasound, followed by endoscopic retrograde cholangiopancreatography and/or percutaneous cholangiography in 3 cases. Radiological findings included common hepatic duct complete obstruction in 1 case, common hepatic duct stenosis in 2 cases, common bile duct obstruction in 1 case, and intrahepatic bile ducts dilation without a well-recognized obstruction in 1 case. Two patients were treated by sequentially percutaneous biliary drainage and balloon dilation while 1 patient had an endoscopic transpapillary biliary prosthesis placed. Percutaneous or endoscopic procedures obtained the improvement of hepatic function and cholestatic indexes without subsequent jaundice or cholangitis. In two patients suppression of floxuridine infusion allowed the improvement of hepatic function. The present series suggests that in some patients receiving hepatic arterial infusion of floxuridine extrahepatic biliary stenosis may represent the primary event leading to a secondary intrahepatic biliary damage that does not correlate with specific floxuridine toxicity but results from bile stasis and infection, recurrent cholangitis and eventually biliary sclerosis. Aggressive research for extrahepatic biliary sclerosis is advised, since an early nonsurgical treatment of extrahepatic biliary stenosis may prevent an irreversible intrahepatic biliary sclerosis worsening the prognosis of metastatic liver disease.- - - - - - - - - - ranking = 0.5keywords = cycle (Clic here for more details about this article) |
4/14. Weekly irinotecan in a patient with metastatic colorectal cancer on hemodialysis due to chronic renal failure.BACKGROUND: The cytotoxic treatment of patients suffering from advanced or metastatic cancer undergoing hemodialysis due to chronic renal failure still remains a problem, since for those patients pharmacokinetic and pharmacodynamic data on most cytotoxic agents are lacking. CASE REPORT: We report a 45-year-old male who suffered from chronic renal failure and was diagnosed with stage-3 colorectal cancer (CRC) in February 2000. After surgical removal of the tumor an adjuvant chemotherapy of dose-reduced i.v. bolus 5-fluorouracil and folinic acid was begun (Mayo protocol). Due to excessive gastrointestinal toxicity, therapy was discontinued after the first cycle. In April 2000 liver metastases were diagnosed. The patient was then put on a weekly schedule of dose-reduced CPT-11 (50 mg/m(2), 80 mg total). No hematological or non-hematological toxicity grade 3/4 was observed. Due to excellent tolerability and lack of severe side effects the dose was increased up to 80 mg/m(2) (140 mg total) weekly. A dose escalation to 100 mg/m(2) (180 mg total) resulted in severe diarrhea (grade 4). Within 2 months of treatment the patient achieved a lasting partial remission until April 2001 (12 months). A significant progression of hepatic metastases required an alternative treatment regimen beginning in July 2001 (HAI, hepatic artery infusion). CONCLUSION: This case report demonstrates the feasibility and efficacy of a weekly treatment with dose-reduced CPT-11 in a patient with metastatic CRC on hemodialysis due to chronic renal failure.- - - - - - - - - - ranking = 0.25keywords = cycle (Clic here for more details about this article) |
5/14. Investigation into the usefulness and adverse events of CDDP, 5-fU and dl-leucovorin (PFL-therapy) for advanced colorectal cancer.Biochemical modulation of 5-fluorouracil (5-FU) has been verified the evidence of significant improvement of survival and quality of life in patients with advanced colorectal carcinoma. We investigated the therapeutic and adverse drug reaction of intensive chemotherapy using cisplatin (CDDP), 5-FU and dl-leucovorin (LV) (PFL-therapy), which may be producing dual biochemical modulation effect of 5-FU for advanced colorectal carcinoma. Administration schedule was 13 mg/m2 of CDDP, 300 mg/m2 of 5-FU, and 30 mg/body of dl-LV for 5 consecutive days. This regimen was repeated at 3-week intervals in hospital. Sixteen patients were enrolled in this study, most of whom had a history of previous chemotherapy as adjuvant treatment, and the response rate was 25%, with four patients having "partial response" and eight "no change". In respect to performance status, 46% of patients who completed the protocol were markedly improved in spite of their poor performance status before treatment. Moreover, when patients were classified into two groups based on changes of the serum level of CEA, "responder in CEA level" showed better prognosis than "non-responder in CEA level". Major toxicities were nausea, hyperglycemia and neutropenia. Three patients experienced Grade 4 hematological side effect, but these complications resolved quickly in all patients except for one patient. PFL-therapy is effective for advanced colorectal cancer with large tumor burden and showed the same prognostic result as the American and European trials in spite of smaller number of treatment cycles and a history of previous chemotherapy. We will be able to demonstrate the usefulness of this regimen for Japanese patients with advanced colorectal cancers after adding new cases to the present report.- - - - - - - - - - ranking = 0.25keywords = cycle (Clic here for more details about this article) |
6/14. An immediate hemolytic reaction induced by repeated administration of oxaliplatin.BACKGROUND: platinum-based chemotherapy agents have been associated with potentially fatal acute immune-mediated hemolytic anemia. The target antigen, cause of the positive direct antiglobulin test (DAT) and mechanism of hemolysis have been the subject of controversy. CASE REPORT: We report a patient who developed a DAT-positive hemolytic episode after a red cell (RBC) transfusion was delivered during the infusion of her 17th cycle of oxaliplatin. Standard pretransfusion testing was uncomplicated; however, after infusion, the serum was no longer compatible with the transfused units and a strong (4 ) panreactive IgG antibody was detected. RESULTS: The patient's serum from 10 days after the episode, only when therapeutic concentrations of oxaliplatin were added, reacted with all RBCs tested using the indirect antiglobulin test (IAT) (3 ). The effect was retained with a purified IgG fraction and almost eliminated with IgG-depleted serum. immunoprecipitation analysis revealed a band with the molecular weight of the Band 3 anion channel only in the presence of the patient's serum and oxaliplatin. CONCLUSION: Our investigations indicated that oxaliplatin interacted with both an IgG antibody and a RBC membrane epitope probably located on the Band 3 anion channel.- - - - - - - - - - ranking = 0.25keywords = cycle (Clic here for more details about this article) |
7/14. octreotide LAR resolves severe chemotherapy-induced diarrhoea (CID) and allows continuation of full-dose therapy.Severe diarrhoea after chemotherapy is a dose-limiting toxicity of first-line chemotherapeutic agents approved for the treatment of colorectal cancer including 5-fluorouracil leucovorin (5-FU/LV) and irinotecan (CPT-11). This report explores the potential of the long-acting version of the somatostatin analogue octreotide, for secondary prophylaxis in patients suffering from chemotherapy-induced diarrhoea (CID). A case series of three patients in a general community setting with colorectal cancer and severe refractory diarrhoea after fluoropyrimidine or irinotecan therapy resulting in suspension of chemotherapy, hospitalization, and/or refusal of further treatment. After the failure of initial aggressive antidiarrhoeal therapy with loperamide and/or diphenoxylate-atropine, patients were treated with octreotide LAR (30 mg q28d). The ability of octreotide LAR to resolve diarrhoea, prevent further episodes of grade 3 or 4 gastrointestinal toxicity and prevent costly hospitalizations. octreotide LAR 30 mg q28d speed resolution of diarrhoea and was able prevent further episodes during subsequent cycles of chemotherapy. One patient who initially refused chemotherapy because of CID was able to complete his treatment. All patients reported improvement in quality of life following resolution of diarrhoea with octreotide LAR and no further hospitalizations because of CID were necessary.- - - - - - - - - - ranking = 0.25keywords = cycle (Clic here for more details about this article) |
8/14. Oxaliplatin-induced acute-onset thrombocytopenia, hemorrhage and hemolysis.BACKGROUND: Oxaliplatin is a novel platinum derivative with established anti-tumor activity in colorectal cancer. Acute-onset hemolytic anemia and thrombocytopenia associated with this drug have rarely been reported and some of these cases have been severe or even fatal. CASE REPORT: This case report describes a patient who developed fever, chills, abdominal and back pain as well as sudden-onset severe thrombocytopenia, upper gastrointestinal bleeding and hemolysis immediately after treatment with oxaliplatin for metastatic colorectal cancer. The reaction appeared during the 14th cycle of chemotherapy. Corticosteroids and antihistamines were administered together with platelet transfusions. Over the next 2 days platelet count improved and the syndrome abated. The patient was discharged 4 days later. Furthermore, the reaction was accompanied by a strongly positive coombs test and increased TNF-alpha and IL-10 serum levels which returned to normal following anti-inflammatory drug administration. CONCLUSION: physicians should be aware of the possibility of acute hematological emergencies following oxaliplatin administration.- - - - - - - - - - ranking = 0.25keywords = cycle (Clic here for more details about this article) |
9/14. Oxaliplatin-induced immune pancytopenia.BACKGROUND: Oxaliplatin, a third-generation platinum compound, has been implicated in isolated cases of immune hemolytic anemia and/or immune thrombocytopenia. The first case of severe immune pancytopenia related to oxaliplatin is described. PATIENT AND methods: A 79-year-old woman with colorectal cancer was initially treated with 5-fluorouracil and she later received oxaliplatin and leucovorin every 2 to 4 weeks. During the 15th and 17th cycles of chemotherapy she developed thrombocytopenia, hemolysis, and neutropenia. No problems occurred during the 16th cycle without oxaliplatin. Serologic testing including detection of drug-dependent antibodies and autoantibodies was performed with standard techniques. RESULTS: Serologic findings included a positive immunoglobulin g direct antiglobulin test; nonreactive red blood cell (RBC) eluates; platelet (PLT)-bound antibodies to glycophorin (GP) IIb-IIIa, GPIb-IX, and GPIa-IIa; and oxaliplatin-dependent antibodies to PLTs, RBCs, and neutrophils. CONCLUSION: Oxaliplatin may lead to the production of ddabs to RBCs, PLTs, and neutrophils. Thus the risk of immune cytopenias should always be considered in patients treated with oxaliplatin.- - - - - - - - - - ranking = 0.5keywords = cycle (Clic here for more details about this article) |
10/14. Oncologic emergencies secondary to advanced colorectal cancer successfully treated with oxaliplatin/5-fluorouracil/leucovorin: report of three cases.Metastatic/advanced colorectal cancer is considered a resistant disease and oncologic emergencies secondary to advanced disease may be regarded with a nihilistic attitude. The objective of this report is to emphasize the efficacy of the oxaliplatin/5-fluorouracil/leucovorin regimen (FOLFOX-4) in three patients presenting oncologic emergencies secondary to advanced colon cancer. The first case was a 40-year-old man with severe respiratory insufficiency due to massive carcinomatous lymphangitis; subsequently a cecal adenocarcinoma was diagnosed. The patient's conditions became life-threatening and he was admitted to the intensive care unit. The second case was a 41-year-old woman presenting with fever, abdominal mass and pain. Ultrasound and CT-scan revealed two hepatic masses (13 x 15 and 15 x 20 cm), diagnosed as liver metastases from colon cancer. The patient's condition deteriorated with intestinal obstruction secondary to the large left liver mass. The third case was a 58-year-old woman presenting with hepatic mass, fever and weight loss. Ultrasound and CT-scan showed a liver lesion occupying the right lobe (12 x 14 cm). Ultrasonically-guided biopsy and colonoscopy showed liver metastases from cecal cancer. A 5-fluorouracil/leucovorin regimen failed to improve her clinical condition and she had disease progression, inferior vena cava neoplastic thrombosis and right hydronephrosis. All three patients rapidly improved after a few cycles of oxaliplatin-containing chemotherapy. These cases demonstrate that even patients with advanced colorectal cancer presenting with oncologic emergencies and life-threatening conditions can be successfully treated with the FOLFOX-4 regimen.- - - - - - - - - - ranking = 0.25keywords = cycle (Clic here for more details about this article) |
