Ifosfamide/mesna as salvage therapy in platinum pretreated ovarian cancer patients--long-term results of a phase II study.

PURPOSE: Salvage chemotherapy in advanced ovarian cancer is not yet standardized. PATIENTS: Twenty-one consecutive patients progressing on or relapsing after previous platinum-containing treatment were eligible for treatment with ifosfamide 5 g/m(2) infused over a 24-hour period every 3 weeks in a Phase II trial. After an initial bolus of 1 g/m(2) of mesna, mesna was applied at a dosage of 5 g/m(2) concomitantly with ifosfamide followed by additional dosages of 200 mg 3 times at 4-hour intervals after termination of the ifosfamide infusion. RESULTS: The rate of objective responses was 19 percent, with a 95%CI [5.45-41.91 percent]. One patient achieved a pathologic complete remission (pCR) and 3 patients a clinical partial remission (PR). Median time-to-progression was 3 months. One patient was a long-term survivor. Main toxicities according to NCI-CTC included Grade 4 neurotoxicity in one patient, Grade 3 gastrointestinal toxicity in 5 patients, Grade 3 infection in one patient, and Grade 3 and 4 leucopenia in 6 and 2 patients, respectively. CONCLUSIONS: Monotherapy with ifosfamide represents an active regimen for salvage chemotherapy in advanced ovarian cancer patients progressing on or relapsing after previous platinum-pretreatment, even yielding a long-term surivor.

Phase I/II study of oral etoposide plus GM-CSF as second-line chemotherapy in platinum-pretreated patients with advanced ovarian cancer.

The aim of this phase I/II study was to determine the maximum tolerated dose (MTD) and the dose-limiting toxicities of chronic oral etoposide given on days 1-10 followed by rescue with subcutaneous (s.c.) granulocyte-macrophage colony-stimulating factor (GM-CSF) on days 12-19 as second-line chemotherapy in platinum-pretreated patients (pts) with advanced ovarian carcinoma. Cohorts of three to six pts were treated with doses of oral etoposide from 750 mg m(-2) cycle(-1) escalated to 1250 mg m(-2) cycle(-1) over 10 days, every 3 weeks. Subcutaneous GM-CSF, 400 mug once daily, days 12-19, was added if dose-limiting granulocytopenia was encountered. In total, 18 pts with a median Karnofsky index of 80% (range, 70-100%) and a median time elapsed since the last platinum dose of 10 months (range, 1-24 months), 30% of whom showed visceral metastases, were treated at four dose levels (DLs) of oral etoposide on days 1-10 of each cycle as follows: DL 1, 750 mg m(-2) cycle(-1), without GM-CSF, three pts; DL 2, 1000 mg m(-2) cycle(-1), without GM-CSF, three pts; DL 3, 1000 mg m(-2) cycle(-1), with GM-CSF, six pts; and DL 4, 1250 mg m(-2) cycle(-1), with GM-CSF, six pts. All pts were assessable for toxicity and 16 pts for response. Dose-limiting toxicity (DLT) was reached at DL 4 by three of six pts, showing World Health Organization (WHO) toxicity grade 4. One patient died from gram-negative sepsis associated with granulocytopenia grade 4. Two more pts developed uncomplicated granulocytopenia grade 4. Thus, we recommend that DL 3 can be used for further phase II evaluation (i.e. oral etoposide 1000 mg m(-2) cycle(-1), days 1-10, followed by s.c. GM-CSF 400 mug, days 12-19). The clinical complete or partial responses in each patient cohort were: DL 1, one of three pts; DL 2, one of three pts; DL 3, three of five pts; and DL 4, two of five pts. In conclusion, in this phase I/II study, we defined the MTD and the dose recommended for the therapy with oral etoposide given over 10 days followed by s.c. GM-CSF in platinum-pretreated patients with advanced ovarian cancer. Our data demonstrate encouraging activity of this regimen and strongly support its further investigation in a phase II study.

Reactivity of urinary bladder smooth muscle in guinea pigs to acetylcholine and carbachol--participation of acetylcholinesterase.

The authors examined the influence of acetylcholinesterase inhibitor (neostigmine) on the in vitro reactivity of urinary bladder smooth muscle (UBSM) in guinea pigs. The aim of the present study was to determine the participation of pharmacokinetic properties of acetylcholine and carbachol in different UBSM reactivity to these mediators. In vitro method of organ baths was used and reactivity of UBSM strips to cumulative doses of acetylcholine and carbachol was tested before and after the incubation with neostigmine (10(-4) mol.l(-1)). Neostigmine caused a significant increase of UBSM reactivity to acetylcholine. The UBSM reactivity to acetylcholine was significantly higher at concentrations of 10(-5) and 10(-4) mol.l(-1) compared to carbachol at the same concentrations. These findings indicate that in addition to different mediator affinity to muscarinic receptors and to their different intrinsic activity, the pharmacokinetic properties of acetylcholine and carbachol also participate in UBSM reactivity.

Effective salvage therapy with carboplatin/mitomycin C in metastatic breast cancer.

BACKGROUND: Alternative and effective drug regimens in patients with metastatic breast cancer progressing after adriamycin- and taxoid-containing regimens are urgently needed. PATIENTS AND METHODS: In a phase II trial, 43 heavily pretreated patients with metastatic breast cancer were treated with both carboplatin 200 mg/m(2) i.v. and mitomycin C 10 mg/m(2) i.v. on day 1 every 4 weeks. In case of granulocytopenia or thrombocytopenia below grade 3 according to NCI-CTC, the carboplatin dosage was escalated to 300, 400, and 450 mg/m(2) in the next treatment cycle. RESULTS: During the first 3 cycles the dose intensity of carboplatin could be increased from a mean of 50 to 74 mg/m(2)/week. Beyond this value the carboplatin dose intensity decreased because of hematotoxicity. Based on an intention-to-treat analysis, 9 of 43 patients responded to therapy (21%; 95% CI = 10.04-36.04) including 2 complete and 7 partial responses. 15 patients had no change, 13 progressed, and 6 patients were considered nonevaluable. The median time to progression was 3 (range 0-12) months. NCI-CTC grade 3 or 4 granulocytopenia was observed in 14 patients, grade 3 or 4 thrombocytopenia occurred in 32, grade 3 infections in 3, grade 3 hemorrhage in 1, and grade 3 cardiac dysrhythmias in 1 of the patients. CONCLUSIONS: In anthracycline/ taxoid-pretreated patients, salvage treatment with a combination of carboplatin and mitomycin C seems to be effective and associated with foreseeable toxicity. Based on our results with an intraindividual dose escalation of carboplatin, a dosage of 300 mg/m(2) in combination with mitomycin C 10 mg/m(2) every 4 weeks seems to represent a recommendable starting dose for future studies.

Octreotide combined with goserelin in the therapy of advanced pancreatic cancer--results of a pilot study and review of the literature.

The two hormone analogues octreotide and goserelin have been shown to decelerate growth of human pancreatic cancer in vitro and in vivo. The objective of this pilot study was to investigate the efficacy and toxicity of the combination of these two agents in patients with advanced pancreatic cancer. Octreotide was injected subcutaneously in dosages increasing weekly, starting with 50 micrograms twice daily, until the level of maintenance therapy of 500 micrograms three times a day was reached. In addition, 3.8 mg goserelin acetate was administered subcutaneously at monthly intervals. A median of 7 cycles (range 1-27 cycles) were applied; 13 out of 14 patients entered into the study were evaluable for response and all 14 were evaluated for toxicity. In one patient with initially non-resectable pancreatic cancer, systemic therapy yielded a partial remission lasting 9 months. The degree of tumour regression then allowed a consecutive macroscopic radical tumour resection followed by an additional 6 months of no evidence of disease while the same drug combination was continued. In an additional 9 patients, no change of disease was observed, in some cases for a remarkably long time (up to 27 months). Nevertheless, the objective response rate of 7% (95% confidence interval 0 +/- 21%) was low. In 5 patients a clear improvement in their performance status was seen soon after the start of therapy; 3 patients showed progression of the disease at first evaluation or earlier and 1 patient was not evaluable at the time of study assessment. According to the product-limit method of Kaplan and Meier, the time to progression was 3.0 +/- 1.8 months [median +/- asymptotic standard error (ASE)] and overall survival was 6.0 +/- 1.5 months (median +/- ASE). Toxicity was rare and only of mild to moderate degree. Overall, the regimen under investigation did not meet the criteria for sufficient antitumoural effectiveness. Nevertheless, this study reinforces the concept that pancreatic cancer is principally responsive to endocrine therapy and therefore the further investigation of hormonal manipulation seems worth while in the future.

Randomized open label phase III trial of CEOP/IMVP-Dexa alternating chemotherapy and filgrastim versus CEOP/IMVP-Dexa alternating chemotherapy for aggressive non-Hodgkin's lymphoma (NHL). A multicenter trial by the Austrian Working Group for Medical Tumor Therapy.

Primary end point of this trial was to reduce neutropenic infections during the treatment of aggressive NHL with CEOP/IMVP-Dexa (cyclophosphamide, epirubicin, vincristine, prednisolone ifosfamide, methotrexate, VP-16, and dexamethasone). Further, we studied the influence of filgrastim on dose intensity of CEOP/IMVP-Dexa, on the rate of complete remissions, on the time to relapse, and on survival. Eighty-five patients with untreated large-cell NHL were randomized to one of two treatment arms; 74 patients were eligible. Thirty-eight patients in arm 1 were treated with CEOP/IMVP-Dexa chemotherapy and filgrastim, 36 in arm 2 with CEOP/IMVP-Dexa chemotherapy alone. In arm 1 filgrastim was self-injected by the patients at 5 micrograms/kg body wt. s.c. daily, except on the days when cytotoxic drugs were given. During treatment we did weekly complete blood counts. Median leukocyte counts were 10.91 x 10(9)/l and 5.46 x 10(9)/l in arm 1 and 2, respectively (p = 10(-6)). Median neutrophil counts were 7.7 x 10(9)/l in arm 1 and 2.72 x 10(9)/l in arm 2 (p < 10(-6)). Median neutrophil nadirs were 0.199 x 10(9)/l and 0.213 x 10(9)/l in arm 1 and 2, respectively (p = 0.09). Mean platelet nadirs were 95 and 152 x 10(9)/l (p = 0.000004) and mean hemoglobin nadirs 83.95 g/l and 92.78 g/l (p = 0.00558) in arm 1 and 2, respectively. Dose intensity of CEOP/IMVP-Dexa was 82.3% and 76.2% in arm 1 and 2, respectively (p = 0.041). Forty-two percent and 58% of patients experienced a febrile neutropenia in arm 1 and 2, respectively (not significant, NS). Median time to first neutropenic infection was in treatment week 11 and 6 in arm 1 and 2, respectively (NS). There was no significant difference in rate, duration, and kind of infection, duration of hospitalization, or antibiotic treatment. Seven toxic deaths occurred, all due to neutropenic infection, 6 and 1 in arm 1 and 2, respectively (p = 0.0732). Four of the six patients, who died of infection in arm 1 were older than 60 years. Complete remission rate was 83% and 66.7% in arm 1 and 2, respectively (NS). After a median observation time of 3 years there was no difference in time to relapse or survival. Filgrastim increases leukocyte and neutrophil counts and dose intensity, if used with CEOP/IMVP-Dexa chemotherapy in high-grade lymphomas. There was no significant effect on febrile neutropenia or infections. The more frequent fatal neutropenic infection rate in the filgrastim arm was not statistically significant. It is most appropriate to explain it by the patient's age in combination with the high dose intensity. The small increase in dose intensity had no effect on survival but probably decreased hemoglobin levels and platelet counts in arm 1. We were unable to show a benefit for filgrastim in combination with CEOP/IMVP-Dexa.

In vitro and in vivo evaluation of the combination of cisplatin and its analogue carboplatin for platinum dose intensification in ovarian carcinoma.

BACKGROUND: Cisplatin and its analogue carboplatin have been shown to cause dose-dependent growth inhibition throughout a wide dose range in the ovarian cancer cell lines OVCAR-3, 2780, HTB-77, and CRL-1572 tested. Cisplatin was 30 times more effective than carboplatin. The combination of both substances led to a less-than-synergistic effect, as was revealed by an isobologram in the OVCAR-3 cell line. Because of the different toxicity pattern, cisplatin and carboplatin theoretically are ideal candidates for combination chemotherapy in platinum-sensitive tumors. METHODS: In a Phase II study, the efficacy, the toxicity profile, and the feasibility of combining both substances were assessed in 20 previously untreated patients with ovarian cancer. The regimen consisted of carboplatin (300 mg/m2) on day 1, followed by cisplatin (100 mg/m2) on day 2 every 4 weeks. RESULTS: A total of 81 cycles were administered (median, 4 cycles; range, 1-6 cycles); four patients experienced complete remission and three experienced clinical partial remissions. Limiting toxicities were thrombocytopenia, leukopenia, and ototoxicity. The mean (+/- standard deviation [SD]) carboplatin and cisplatin dose intensities (DI) reached during the first four cycles of therapy were 58 mg/m2/week (+/- 18 mg/m2/week) and 21 mg/m2/week (+/- 7 mg/m2/week), respectively, which corresponded closely to the projected DI of 75 and 25 mg/m2/week, respectively. Based on the equivalence ratio of 4:1, the DI of carboplatin has been converted into the respective cisplatin DI, resulting in a total DI estimate. The overall DI of 37 mg/m2/week (+/- 14 mg/m2/week) was close to the projected one of 44 mg/m2/week. CONCLUSIONS: Combining cisplatin with carboplatin was found to represent a feasible and efficacious therapeutic strategy for increasing platinum dose intensity.

Etoposide and carboplatin as salvage and first-line therapy in ovarian cancer patients.

BACKGROUND: The agents etoposide and carboplatin are active against ovarian cancer and display synergistic anti-tumor activity in animal tumor models. The objective of these two phase II trials was to determine the efficacy and toxicity of the combination of etoposide with carboplatin in previously treated and untreated patients with ovarian cancer. PATIENTS AND METHODS: Etoposide (100 mg/m2) was administered as a one-hour infusion on three consecutive days and carboplatin (400 mg/m2) as a 30-minute infusion on day 2 of each monthly scheduled cycle. In 20 patients, previously treated with cisplatin-containing regimens, a total of 102 cycles was applied as salvage therapy (ST) and in 27 patients, a total of 168 cycles as first-line therapy (FLT). RESULTS: ST yielded 2 complete remissions (CR) and one partial remission (PR); in 7 patients, no evidence of disease (NED) and in 6 patients, no change (NC) were observed. The progression-free intervals (PFI) lasted a median 7.0 months (range < 2-14 months). FLT resulted in 7 CR (4 of them pathologically (p) verified), 11 NED (1 pNED), 3 PR (1 pPR) and 6 NC. The objective response rate was 63% (95% confidence interval: 36-89%). PFI lasted a median 8.0 months (range 3-25+ months); median survival had not been reached at the time of evaluation. Thrombocytopenia (WHO grade 4) was the limiting toxicity. CONCLUSIONS: Although not fulfilling the expectations of synergistic activity as shown in preclinical models, the combination of etoposide with carboplatin is an active and feasible therapy regimen in the out-patient management of ovarian cancer.

Computer-aided individual prognoses of squamous cell carcinomas of the lips, oral cavity and oropharynx.

Computer-aided individual prognoses (CIP) is a software-package developed on the basis of an empirical study and can be installed on any IBM-compatible personal computer. The project which went into the making of CIP was called "Prospective DOSAK-study on squamous cell carcinomas of the lips, oral cavity and oropharynx". In the course of the study 1485 patients were treated between 1977 and 1982, and followed up through 1985. CIP facilitates individual prognoses and comparisons of independent patient groups with parallel groups from the data of the above-mentioned study. In practical clinical work individual prognoses allow exact and reliable judgements on individual patients. In clinical cancer research it provides the information about prognostic factors required for controlled clinical studies. The comparison of independent patient populations allows for an ongoing qualitative control of the patients in each clinical institution. In clinical cancer research such a comparison means that certain characteristics of the patient, the tumor and of the disease can be given higher prognostic value. The same is true of the clinical testing of therapeutic measures which is typically carried out during phase-II-studies. Due to its menu-based organization CIP does not presuppose any specialist knowledge on the part of its users and can be regarded as particularly user-friendly.

Clonogenic growth in vitro: an independent biologic prognostic factor in ovarian carcinoma.

A retrospective analysis was performed to investigate the prognostic value of growth in a human tumor clonogenic assay system for 84 ovarian cancer patients. A significant difference in survival probability (determined by the method of Kaplan-Meier) was found by univariate analysis between patients with ovarian carcinoma whose tumors manifested clonogenic growth (defined as growth of greater than or equal to five colonies per plate) and patients whose tumors did not grow. Clonogenic growth in vitro was associated with worse prognosis (P = .007, log-rank test). A number of generally accepted prognostic factors, International Federation of Gynecology and Obstetrics (FIGO) stage (P = .003), residual tumor mass (P less than .001), and grade (P = .011), were also of prognostic importance in our patient population. Multivariate analysis, based on the Cox regression model, identified clonogenic growth as a significant independent prognostic parameter in ovarian carcinoma (P = .031), in addition to the conventional risk factors. Estimation of survival of individual patients was best accomplished by combining the factors of residual tumor mass (P less than .05), age (P less than .01), and clonogenic growth (P less than .05) (in sequence of decreasing potential of risk).

Analysis of factors influencing clonogenic growth in vitro of cells from ovarian carcinoma patients.

Clonogenic growth (defined as the formation of greater than or equal to 5 colonies per 5 x 10(5) viable nucleated cells per plate) of ovarian cancer specimens assessed in our clonogenic assay system was significantly associated with the proportion of tumor cells in the suspensions plated (N = 87; P = 0.0006), although there was no quantitative relationship with the corresponding plating efficiencies. An inverse correlation was observed between monocytes/macrophages/mesothelial cells (M) proportion and clonogenic growth (P = 0.013). These associations were most evident when only effusions were considered. Univariate analyses identified tumor cell content, M proportion and, to a lesser degree, granulocyte content as the only factors out of 12 examined to be correlated with colony formation. Multivariate analysis using a logistic regression model identified the proportion of tumor cells as the only significant factor predicting clonogenic growth in vitro (P = 0.0006). The overall accuracy of prediction for growth or non-growth was 63.2%.

Early prediction of deep sternal wound infection after heart operations by alpha-1 acid glycoprotein and C-reactive protein measurements.

Serum C-reactive protein (CRP) and alpha 1-acid glycoprotein (AAG) levels were studied in 188 patients undergoing heart operations with cardiopulmonary bypass. Mediastinitis or osteomyelitis of the sternum or both developed in 10 patients on postoperative day 4 to 13 (median, day 9). The mean CRP levels on day 2 were lower in patients with later deep sternal wound infection (9.1 +/- 1.5 mg/dl [mean +/- standard error]) compared with patients without major infections (14.0 +/- 0.8 mg/dl; p = 0.103 [univariate logistic regression]). AAG levels on day 2 reacted in a similar manner, yielding 78.2 +/- 5.5 mg/dl and 100.9 +/- 2.7 mg/dl, respectively (p = 0.0004). No correlation was found between CRP or AAG and duration of cardiopulmonary bypass, number of blood transfusions, or total protein levels on day 2. The white blood cell count (WBC) on day 2 was 13.1 +/- 1.7 X 10(3)/microliter for patients with infection and 9.7 +/- 0.3 for those without infection. Multivariate logistic regression analysis revealed that AAG, WBC, and CRP on day 2 were significant risk factors sufficiently predicting the probability of a deep sternal infection. After adjustment for these three variables, other variables (age, sex, total protein on day 2, diabetes mellitus, type of operation, duration of cardiopulmonary bypass, length of operation, repeat thoracotomy for bleeding, number of blood transfusions on the day of operation, intraaortic balloon pumping, reoperation, emergency operation, and surgeon's professional status) were not of additional significance. The goodness of fit of the statistical model was confirmed by a high correspondence between predicted and observed cases of deep sternal infection.(ABSTRACT TRUNCATED AT 250 WORDS)

Biostatistical aspects of adjuvant therapy assay.

The specific problems of biostatistical evaluation of adjuvant therapy are discussed. These problems arise from the fact that the effect of adjuvant therapy is usually rather small; in particular, for many kinds of cancer it is smaller than the variability in prognosis among patients due to different prognostic factors. Knowledge about prognostic factors for a particular type of cancer is therefore an essential precondition for the correct planning of controlled clinical trials. The importance of prognostic factor studies is stressed and it is shown how results of such studies can be utilized for the design of efficient trials for adjuvant therapy assay. The results of the retrospective DOSAK study on carcinomas of the oral cavity are reported. Based on a sample of 1021 patients in this study, numerous prognostic factors were analysed by both univariate and multivariate statistical techniques. On the basis of these analyses, a prognostic index was developed which should be a valuable aid for the design of clinical trials.

Risk factors for severe bacterial infections after valve replacement and aortocoronary bypass operations: analysis of 246 cases by logistic regression.

Risk factors for severe bacterial infections, that is, deep sternal wound infection, pneumonia, septicemia, and prosthetic valve endocarditis, were evaluated in 246 consecutive patients undergoing valve replacement (N = 84) or aortocoronary bypass operation (N = 162). Multiple logistic regression analysis was applied to determine the ability of putative risk factors to predict infection. The risk factors considered were age, sex, diabetes mellitus, duration of cardiopulmonary bypass (CPB), duration of operation, amount of blood restored on the day of operation, repeat thoracotomy for bleeding, intraaortic balloon pumping, reoperation, emergency operation, and the professional status of the surgeon. Severe infections occurred in similar frequency after valve replacement (8/84; 9.5%) and aortocoronary bypass (11/162; 6.8%). For patients who had a bypass procedure, repeat thoracotomy was the only factor significantly associated with infection (p = 0.0004). However, the classification analysis revealed that this variable alone is too unspecific for a reliable prediction. Univariate analysis indicated that restoration of more than 2,500 ml of blood (p = 0.0001), reoperation (p = 0.0821), duration of operation (p = 0.0061), duration of CPB (p = 0.0318), and intraaortic balloon pumping (p = 0.0281) were associated with infection following valve replacement. A model with three variables emerged from the multiple logistic regression: after correction for blood restoration, reoperation, and duration of CPB, no other variable was of additional predictive value. For patients who underwent valve replacement, the model performed well in predicting complications. The classification analysis revealed a high correspondence between observed and predicted instances of infection: it correctly predicted 75% of the patients with infection and 96% of those without infection.(ABSTRACT TRUNCATED AT 250 WORDS)

Retrospective DOSAK Study on carcinomas of the oral cavity: results and consequences.

In a multicentre, retrospective observational study on carcinomas of the oral cavity, including the lips and oropharynx, data material of 1021 patients has been analysed. The specific goals of this study were: Review of existing proposals for classification. Analysis of prognostically relevant factors of the tumour disease. Construction of a prognostic index for the determination of individual and collective prognoses. The following results were achieved: ad 1: All existing TNM-Classifications of oral cavity carcinomas so far fail to meet the requirements of the necessary criteria. ad 2: The multivariate analyses of prognostically relevant factors were performed with and without taking therapeutic factors into account. The results show unequivocally that reliable prognoses are only possible if various treatment modalities are considered. ad 3: This led to the construction of the treatment-dependent prognostic index TPI, which will be eligible for use in clinical-therapeutic cancer research and in clinical practice.

Fever, leucocytosis and infection after open heart surgery. A log-linear regression analysis of 115 cases.

A prospective investigation was undertaken in adults to assess the specificity and sensitivity of fever (greater than 38 degrees C) and leucocytosis (greater than 10 000/microliters) for the diagnosis of infection after operations with cardiopulmonary bypass. A log-linear model analysis of a multiway frequency table was used for statistical evaluation. The model parameters were separately evaluated for 2 periods: the early one until the 6th day, the late period from the 7th postoperative day until discharge. Seven out of 115 patients suffered infections during their hospital stay: Bacteremia occurred in 3, pneumonia in 2, and deep sternal wound infection in 2 patients, and a superficial wound infection in one. No significant interactions between fever, leucocytosis and/or infection were found in the first period, except an inverse relation between fever and elevated WBC (p = 0.0197). After the 6th postoperative day the model parameters did show significant interactions, fever and leucocytosis being more frequent in infected patients. However, the specificity was low: only 15% of the patients with fever or elevated WBC had an infection. The risk of in-hospital infection was significantly higher after a long duration of cardiopulmonary bypass (p = 0.009), and after transfusion of more than 2500 ml of blood on the day of operation (p = 0.001).
