[Feasibility survey (Phase I-II) of a four drugs combination (5-fluorouracil, folinic acid, carboplatin and irinotecan) delivered using a chronomodulated infusion in the treatment of advanced colorectal cancer].

Seventeen colorectal cancer patients received as first (12 cases) or second line (5 cases) treatment a combined chronotherapy with CPT 11 (infused at day 1 from 2 to 8 am; peak at 5 am), given with 5 FU (700 mg/m2 per day ; days 2-5) and folinic acid (300 mg/m2 per day, days 2-5) both infused from 10 pm to 10 am with a peak at 4 am, and carboplatin (40 mg/m3/day - days 2-5 ; infused from 10 am to 10 pm - peak at 4 pm). The doses of CPT 11 could be easily increased from 120 up to 180 mg/m2 in successive cohorts of four patients through acceptable toxicity. Thus, five patients have already been treated in the phase II part of the trial. An interesting tumoral outcome has been observed: 88% major responses with no progression; median time to progression: nine months and median survival: 19.7 months.

[Chronotherapy combining 5-fluorouracil, folinic acid and carboplatin as first line treatment in metastatic colorectal cancer. A phase 2 study].

Seventy-two patients suffering from a metastatic colorectal cancer received, as first line treatment, a combination chronotherapy with 5-FU and folinic acid (infused from 10 pm to 10 am with a peak at 4 am, respectively at doses of 700 and 300 mg/m2 per day) and carboplatin (infused at the dose of 40 mg/m2 per day from 10 am to 10 pm with a peak at 4 pm). The courses of four days were repeated every two weeks. A major tumoral response was observed in 60% cases (68% in those not previously treated with adjuvant chemotherapy). The median times to progression and overall survival established at 11 and 27 months. The clinical (grades 3-4 in maximum 5% cases) and hematological (grades 3-4 in maximum 10-29% cases) toxicities were quite limited. Our observations suggest the interest to incorporate carboplatin in the combined infusional treatment of colorectal cancer.

Deletion of the 5'-ABL region: a recurrent anomaly detected by fluorescence in situ hybridization in about 10% of Philadelphia-positive chronic myeloid leukaemia patients.

Inclusion of the BCR-ABL ES probe in routine cytogenetics led to the identification of a subgroup of Philadelphia positive (Ph+) chronic myeloid leukaemia patients characterized by a 5'-ABL deletion. This anomaly was observed in 5/51 cases (9.8%). Cytological and clinical data suggest that the 5'-ABL deletion may be associated with dysplastic features of polymorphonuclear cells and metamyelocytes and a short chronic phase duration.

Successful mobilization of peripheral blood HPCs with G-CSF alone in patients failing to achieve sufficient numbers of CD34+ cells and/or CFU-GM with chemotherapy and G-CSF.

BACKGROUND: Mobilization with chemotherapy and G-CSF may result in poor peripheral blood HPC collection, yielding <2 x 10(6) CD34+ cells per kg or <10 x 10(4) CFU-GM per kg in leukapheresis procedures. The best mobilization strategy for oncology patients remains unclear. STUDY DESIGN AND METHODS: In 27 patients who met either the CD34 (n = 3) or CFU-GM (n = 2) criteria or both (n = 22), the results obtained with two successive strategies-that is, chemotherapy and G-CSF at 10 microg per kg (Group 1, n = 7) and G-CSF at 10 microg per kg alone (Group 2, n = 20) used for a second mobilization course-were retrospectively analyzed. The patients had non-Hodgkin's lymphoma (5), Hodgkin's disease (3), multiple myeloma (5), chronic myeloid leukemia (1), acute myeloid leukemia (1), breast cancer (6), or other solid tumors (6). Previous therapy consisted of 10 (1-31) cycles of chemotherapy with additional chlorambucil (n = 3), interferon (n = 3), and radiotherapy (n = 7). RESULTS: The second collection was undertaken a median of 35 days after the first one. In Group 1, the results of the two mobilizations were identical. In Group 2, the number of CD34+ cells per kg per apheresis (0.17 [0.02-0.45] vs. 0.44 [0.11-0.45], p = 0. 00002), as well as the number of CFU-GM (0.88 [0.00-13.37] vs. 4.19 [0.96-21.61], p = 0.00003), BFU-E (0.83 [0.00-12.72] vs. 8.81 [1. 38-32.51], p = 0.00001), and CFU-MIX (0.10 [0.00-1.70] vs. 0.56 [0. 00-2.64], p = 0.001134) were significantly higher in the second peripheral blood HPC collection. However, yields per apheresis during the second collection did not significantly differ in the two groups. Six patients in Group 1 and 18 in Group 2 underwent transplantation, and all but one achieved engraftment, with a median of 15 versus 12 days to 1,000 neutrophils (NS), 22 versus 16 days to 1 percent reticulocytes (NS), and 26 versus 26 days to 20,000 platelets (NS), respectively. However, platelet engraftment was particularly delayed in many patients. CONCLUSION: G-CSF at 10 microg per kg alone may constitute a valid alternative to chemotherapy and G-CSF to obtain adequate numbers of peripheral blood HPCs in patients who previously failed to achieve mobilization with chemotherapy and G-CSF. This strategy should be tested in prospective randomized trials.

[Clinical case of the month. Metastatic endocarditis: clinical observation and review of the literature].

The authors describe a case of metastatic endocarditis associated with a gastric carcinoma. The diagnosis was made early and the treatment by surgery and chemotherapy allowed a survival of 18 months, which is unusually long. The differential diagnosis is discussed and includes nonbacterial thrombotic endocarditis, infectious endocarditis and primary tumors of the heart.
