Die Zweischichtung der tropischen Atmosphäre anhand der "Meteor"-Daten 1965

The tropical circulation exhibits a prominent two-layer structure in the vertical: a moist-unstable lower layer (the "trade layer") with an ITCZ-ward directed mass transport, and a stable upper layer. The aerolo�gical measurements of the German research vessel "Meteor" in Nov.-Dec. 1965 over the Eastern Atlantic (19° W) show that this mean structure is valid even in actual meridional sections, if disturbances are absent. It follows that vertical averages over each of the two layers are appropriate to characterize the tropical atmosphere. In this paper only the trade layer is studied. Its upper boundary is defined by (a) the vertical minimum of static energy; (b) the vertical extreme value of various physical quantities such as temperature and humidity gradients; ( c) constant surfaces of a quantity c which proved useful for the data evaluations. All these definitions are more or less equivalent. The boundary surface is permeable for vertical property transports which are parameterized in terms of the hot tower- and subsidence-process (RIEHL & MALKUS). It is not possible, however, to calculate these fluxes, since meridional profiles of the horizontal mass and energy transport divergence cannot be inferred from the "Meteor" data. The main results are: (1) the static energy surface (a) is always parallel to, but systematically several 100 meters above, the surfaces (b ). (2) The sea surface pressure is practically independent of the trade layer thickness. (3) The components of the horizontal transport of momentum and energy are practically uncorrelated in the vertical; this demonstrates the Hadley-like character of the trade layer. (5) Water vapour plays with > 50% contribution the dominant role in the horizontal energy transport. ( 6) In the diabatic forcing function the flux of latent heat across the sea surface contributes the biggest part.These results show that vertically integrated two-layer models represent the gross features of the tropical circulation. Such formulations are thus a good approach towards simple and straightforward models for numerical experiments

Interferon-alpha does not improve the antineoplastic efficacy of high-dose infusional 5-fluorouracil plus folinic acid in advanced colorectal cancer. First results of a randomized multicenter study by the Association of Medical Oncology of the German Cancer Society (AIO)

BACKGROUND: High-dose 5-FU given weekly as a 24-h infusion in combination with folinic acid (FA) has been associated with low toxicity and a high response rate. Interferon-alpha (IFN) either alone or in combination with FA has also improved treatment results by modulating 5-FU activity. We therefore initiated a randomized multicenter trial comparing the ability of FA or IFN to modulate infusional 5-FU. The statistical design using a sequential analysis allows us to report on the comparison of 5-FU/FA vs. 5-FU/FA/IFN while randomization of patients into 5-FU/FA vs. 5 FU/IFN continues. METHODS: Chemotherapy-naive patients with advanced progressive colorectal cancer and measurable metastatic lesions were randomized to receive 5-FU 2600 mg/m2 i.v. as a 24-h infusion, combined with either FA 500 mg/m2 as a 2-h infusion (A), or IFN 3 x 10(6) U s.c. 3 x/week (B), or the combination of FA plus IFN as in arms A and B (C). Treatment arms were repeated weekly for 6 weeks followed by a 2-week rest period. These 8-week cycles were administered until tumor progression. Because of the occurrence of 2 toxic deaths among the first 17 patients treated in arm C, 5-FU was reduced to 2000 mg/m2 for all patients in arm C. Sequential analysis according to Whitehead for objective response was planned with alpha = 0.05/3 and a power of 80% (beta = 0.2) to detect a difference of > or = 25% (delta = 0.25) or equivalence of response rates. For pairwise comparison of treatment arms a minimum of 30 patients per arm and a maximum of 90 patients per arm were expected in case of equivalence or difference. RESULTS: An interim analysis was performed after the first 93 of 149 randomized patients were evaluable for response and toxicity (A 31 pts, B 33 pts, C 29 pts). Despite the 5-FU dose reduction in arm C, 28% of patients experienced grade 3/4 toxicity (CTC) including diarrhea, mucositis and handfoot syndrome compared to 16% in arm A and 12% in arm B (not significant). No treatment related toxic death occurred in arms A or B, but 3 patients (10%) in arm C died of diarrhea and septicemia. Among patients treated with 5-FU/FA objective tumor response occurred in 12/31 patients (39%) (21%-56%, 95% confidence interval) (3 CR, 9 PR), no change in 13/31 (42%) and PD in 6/31 (19%) patients. Eleven of 29 patients (38%) (20%-56%, 95% confidence interval) receiving 5-FU/FA/IFN achieved complete (3 patients) or partial (8 patients) remissions, 10/29 patients (34%) had stable disease and 8/29 patients (28%) tumor progression. According to the sequential analysis the rates of objective responses observed in patients treated with 5-FU/FA or 5-FU/FA/IFN were equivalent. CONCLUSION: This interim analysis allows the conclusion that infusional 5-FU plus FA/IFN is no more active than infusional 5-FU plus FA alone. However, 5-FU/FA/IFN despite 5-FU dose reduction was associated with unacceptably high toxicity, including 10% deaths. Therefore, further investigation of this regimen is not justified. The study is continued with the comparison of 5-FU/FA vs. 5-FU/IFN

Effective biomodulation by leucovorin of high-dose infusion fluorouracil given as a weekly 24-hour infusion: results of a randomized trial in patients with advanced colorectal cancer

PURPOSE: To determine whether high-dose infusional fluorouracil (FU) is effectively modulated by leucovorin (LV), interferon (IFN) alpha-2b, or both when given to patients with metastatic colorectal cancer. PATIENTS AND METHODS: Patients (n = 236) with progressive, measurable disease were randomized to three groups and received FU 2,600 mg/m2 as a 24-hour continuous infusion (CI) weekly for 6 weeks with 2 weeks rest (FU24h) and LV 500 mg/m2 as a 2-hour infusion before FU or IFN 3 x 10(6) U subcutaneously 3 times weekly or both. Treatment continued until progressive disease or unacceptable toxicity was observed. Pairs of treatment arms were analyzed sequentially to detect equivalence or a 25% difference in response rates. RESULTS: The rate of objective remission in patients who received FU24h/LV (44%; 40 of 91) was significantly higher than in patients who received FU24h/IFN (18%; 16 of 90; P < .05). The response rates of patients who received FU24h/LV versus FU24h/LV/IFN (27%; 13 of 49) were statistically equivalent. Significant differences were observed for time to tumor progression (TTP) (FU24h/LV, 7.1 months; FU24h/IFN, 3.9 months; FU24h/LV/IFN, 6.3 months; global P value < .009) and survival (16.6 months, 12.7 months, 19.6 months, respectively; global P value < .04). Unpredictable and life-threatening toxicity in the FU24h/LV/IFN arm required dose reduction of FU to 2,000 mg/m2/day and early stoppage of this arm. Toxicity was manageable in patients who received both FU24h/LV (grade 3 to 4 diarrhea, 21%) and FU24h/IFN (grade 3 to 4 diarrhea, 15%). CONCLUSION: Response rate, TTP, and overall survival were superior for LV-containing regimens compared with IFN modulation alone. The addition of IFN to high-dose infusional FU plus LV offers no advantage and may increase toxicity. The regimen of high-dose infusional FU24h/LV warrants further evaluation in patients with metastatic colorectal cancer
