A phase I study of sequential irinotecan and 5-fluorouracil/leucovorin.

BACKGROUND: Irinotecan (CPT-11) and 5-fluorouracil (5-FU)/leucovorin are active agents in colorectal cancer. A sequence-dependent synergism of SN-38 followed by 5-FU/leucovorin in vitro led us to conduct a phase I trial of CPT-11 followed by 5-FU/leucovorin to determine the maximum tolerated dose (MTD) and toxicities of this regimen and to obtain preliminary indications of its activity in patients with advanced solid tumors. PATIENTS AND METHODS: Fifty-six patients were enrolled in sequential cohorts to receive escalating doses of CPT-11 (90 min infusion) on day 1, followed by leucovorin 20 mg/m(2) (intravenous push) and 5-FU (90 min infusion) on days 2-5 of each 21-day cycle. RESULTS: A total of 347 treatment cycles (median 4, range 1-25) were administered. Dose-limiting toxicities were diarrhea, neutropenia and fatigue. Nine patients with colorectal cancer and one with gastric cancer had partial or minor responses. Eight of the 10 had prior chemotherapy. CONCLUSIONS: CPT-11 and 5-FU/leucovorin, as constituents of this novel mechanism-based schedule, have promising activity in patients who have received prior chemotherapy. The recommended phase II/III starting doses are CPT-11 275 mg/m(2) over 90 min on day 1, and 5-FU 400 mg/m(2) plus leucovorin 20 mg/m(2) on days 2-5 every 21 days. This combination can be administered safely to this schedule if there is strict adherence to the 90 min infusion time for both CPT-11 and 5-FU.

Methodologic lessons learned from hot flash studies.

PURPOSE: In the course of conducting a series of prospective clinical trials devoted to defining new treatment opportunities for hot flashes in cancer survivors, considerable experience has been acquired with related methodologic issues. This article has been written in response to many queries regarding this methodology. PATIENTS AND METHODS: A series of seven different clinical trials that involved 968 patients was used for this work. Reliable and valid definitions of hot flash intensity were developed from patient-reported descriptions. Concomitant validity and reliability assessment of patient-completed diaries was undertaken to compare hot flash data with toxicity and quality-of-life (QOL) end points and to examine consistency across patient groups using variability analysis and correlation procedures. Parametric data from this meta-analysis was used to examine relative power considerations for the design of phase II and phase III clinical trials. RESULTS: Daily diaries used in these studies exhibited consistency and reliability and had few missing data. Hot flash frequency and hot flash score (frequency multiplied by average severity) variables produced almost identical end point results. For phase III placebo-controlled studies, 50 patients per treatment arm seem appropriate to provide sufficient power specifications to detect a clinically meaningful change in hot flash activity. For phase II trials, 25 patients per trial seem to provide reasonable estimates of eventual hot flash efficacy to screen potential agents for more definitive testing. CONCLUSION: Given the data gained from these experiences, we can plan and carry out more efficient trials to identify efficacious agents for the reduction of hot flash activity.

Neuropeptide Y, leptin, and cholecystokinin 8 in patients with advanced cancer and anorexia: a North Central Cancer Treatment Group exploratory investigation.

BACKGROUND: Anorexia is a noxious symptom, and over half of patients with advanced cancer experience it. Neuropeptide Y (NPY), leptin, and cholecystokinin 8 (CCK8) have been implicated. METHODS: This exploratory study 1) compared circulating concentrations of NPY and leptin between anorectic cancer patients and historic controls and 2) explored whether NPY, leptin, or CCK8 may serve as correlates of anorexia severity. Cancer patients met predefined eligibility criteria: 1) weight loss > or = 2.3 kg over the preceding 2 months and/or a physician-estimated caloric intake of < 20 calories per kilogram of body weight per day and 2) patient acknowledgment that appetite or weight loss was an ongoing problem. RESULTS: Seventy-three cancer patients were studied, and > 90% reported a > or = 50% decline in appetite from baseline in the preceding 2 months. NPY levels were lower than control values: mean +/- standard deviation, 466 pg/mL +/- 161 pg/mL versus 560 pg/mL +/- 151 pg/mL, respectively (P = 0.004). Because a few (but not all) earlier studies suggested an age-related decline in NPY levels, a subgroup analysis was performed and found no age-adjusted difference in NPY levels between groups. Similarly, leptin concentrations were not different between groups. Significant correlations were not observed between anorexia severity and NPY, leptin, or CCK8 levels. CONCLUSIONS: There were no differences in leptin and CCK8 levels between anorectic cancer patients and historic controls. Circulating concentrations of NPY, leptin, and CCK8 did not correlate with anorexia severity. However, the current results suggest a need for further examination of NPY in cancer-associated anorexia.

A simple stratification factor prognostic for survival in advanced cancer: the good/bad/uncertain index.

PURPOSE: This article summarizes the third step of a research program to identify variables that supplement the predictive power of the the Eastern Cooperative Oncology Group (ECOG) performance status (PS) for survival. The objective was to produce a simple, practical, stratification factor for phase III oncology clinical trials involving patients with advanced malignant disease. PATIENTS AND METHODS: A questionnaire was administered to 729 patients with metastatic colorectal or lung cancers. Patients provided a Karnofsky index and appetite rating while physicians provided a survival estimate and the ECOG-PS. Scores for each item were categorized as having a positive, neutral, or negative indication for survival. A patient was classified as having a relatively good prognosis if three or more of the four items showed a positive indication, a bad prognosis if three or more items were negative, and an uncertain prognosis otherwise (Good/Bad/Uncertain [GBU] index). RESULTS: The GBU index improved on the prognostic power of a Cox model quartile index and PS alone and increased the accuracy of survival classification estimates by 5% to 10% more than ECOG-PS alone. For patients with PS of 0 or 1, significant survival patterns exist between GBU groups (P=.002 and.0001, respectively). CONCLUSION: The GBU index may be recommended as a supplementary stratification factor for certain future phase III trials in metastatic lung or colorectal cancer where patient heterogeneity is a particular concern. The GBU represents a relatively modest increase to the cost and patient burden of a clinical trial given the additional control that is achieved over the potentially confounding concomitant to the treatment variable.

Limited sampling models for CPT-11, SN-38, and SN-38 glucuronide.

PURPOSE: We developed limited sampling models (LSMs) for predicting the area under the curve (AUC) of irinotecan (CPT-11) and its metabolites SN-38 and SN-38 glucuronide (SN-38G). PATIENTS AND METHODS: Regression models were developed based on data from a phase I clinical trial involving 34 patients with advanced solid tumor malignancies who received CPT-11 as a 90-min infusion on an every 3-week dosing schedule. Multiple stepwise regression procedures were supplemented by all possible subsets regression analysis. Alternative clinically based and empirically derived LSMs were determined via model validation assessment including bootstrap simulation testing. RESULTS: The best LSMs for CPT-11 AUC included concentrations recorded at the end of infusion and 4 h later with an option to include a blood draw at 7.5 h from infusion start. For SN-38 and SN-38G AUC, optimal LSMs included the additional metabolite concentration at 48 h after infusion. The LSMs were able to predict most patient AUC values to within 10% of the true value. CONCLUSION: CPT-11 AUC can be modeled with acceptable accuracy using only two or three plasma concentration time-points. A variety of LSM alternatives provided comparable accuracy in predicting AUC. Given the wide variety of LSM alternatives, clinical considerations and patient burden become more important performance parameters than statistical considerations for the choice of time-points in constructing LSMs.

Design considerations for efficient prostate cancer chemoprevention trials.

Prostate cancer, even with its substantial public health impact of 180,400 new cases and 31,900 deaths estimated for 2000, still has a very low annual incidence (0.27% for men 34.4 years and older), which makes designing and conducting efficient prostate cancer prevention trials a challenge. Definitive prevention trials with cancer endpoints, such as the Breast Cancer Prevention Trial (BCPT), Prostate Cancer Prevention Trial (PCPT), and Selenium and Vitamin E Cancer Prevention Trial (SELECT), require long trial duration (up to 12 years) and large sample size (up to 32,400 subjects) to accomplish their objectives. This article discusses design concepts for potential prostate cancer prevention trials that require fewer years, subjects, and resources to complete. Design elements, such as high-risk populations, randomization, surrogate endpoints, including quality-of-life endpoints, masking/blinding, and various clinical/statistical designs (including 1-way layout, all-versus-none, factorial, and adaptive designs), are discussed, along with the ultimate goal of gaining US Food and Drug Administration approval for prostate-cancer preventive agents that can improve public health by reducing prostate cancer incidence and mortality.

Quality of Life endpoints in prostate chemoprevention trials.

Although the ultimate goal of any chemoprevention study is to extend life by preventing cancer, it is also important that in doing so, the quality of life is not reduced. Hence, quality of life (QOL) endpoints are secondary only in importance to survival as an endpoint for prostate chemoprevention trials. One can conceptualize QOL endpoints as just another surrogate endpoint biomarker. QOL can be administered and collected in a valid and reliable fashion from cancer patients as demonstrated by numerous clinical trials. To date more than 25 prostate cancer QOL tools have been developed with over 700 different items. However, patients may be asymptomatic, leaving the sensitivity and specificity of the QOL instrumentation in question. Judicious use of a global QOL measure supplemented by protocol-specific or disease-specific instruments is an efficient approach for prostate chemoprevention trials. Clinical significance and missing data considerations need to be elucidated a priori in definitive terms so that results are directly interpretable from the data obtained. The effect of chemopreventive agents on QOL needs to be sufficiently modest to be practical to justify administration in a healthy population. As such, great care needs to be given to a priori determination of the QOL constructs that are most likely to change.

Dyspnea in cancer patients: prevalence and associated factors.

The objectives of this study were to determine the prevalence of dyspnea in the general cancer population, the intensity of the symptom as perceived by the patient, and the patient characteristics associated with the presence of dyspnea. Nine hundred and twenty-three cancer outpatients completed visual analogue scales (VAS) and verbal rating scales (VRS-D) to assess the intensity of their dyspnea. Baseline data included variables that were known covariates of dyspnea. Forty-six percent of the patients had some shortness of breath. Only 4% had a diagnosis of lung cancer and 5.4% lung metastases. Risk factors found to be significantly related to the presence of dyspnea were history of smoking; asthma or chronic obstructive pulmonary disease (COPD); lung irradiation; or a history of exposure to asbestos, coal dust, cotton dust or grain dust (P values from 0.001 to 0.038). The prevalence of dyspnea was strongly related to the number of risk factors a patient had (P < 0.0001). The VAS and VRS-D were significantly correlated, establishing concurrent validity for the VRS-D.

Phase I study of the matrix metalloproteinase inhibitor, BAY 12-9566.

BACKGROUND: Matrix metalloproteinases (MMPs) are involved in tumor invasion and metastasis and have been implicated in breast, ovarian, colorectal, and lung cancer growth. We undertook a phase I study of BAY 12-9566, an inhibitor of MMP-2, MMP-9, and MMP-3, in patients with solid tumors to determine its safety, pharmacokinetics, and effects on potential surrogate markers of biologic activity. PATIENTS AND METHODS: BAY 12-9566 was orally administered daily at four dose levels; 400 mg daily, 400 mg b.i.d., 400 mg t.i.d., and 800 mg b.i.d. Drug disposition was determined on days 1 and 29 with weekly trough levels measured during the first four weeks. Plasma vascular endothelial growth factor (VEGF), basic fibroblast growth factor (bFGF), and urinary pyridinoline and deoxypyridinoline crosslinks were determined at baseline, once weekly for four weeks, and then every four weeks. RESULTS: Thirteen patients were entered on trial. BAY 12-9566 was well tolerated, with only one grade 3 headache, one grade 3 anemia, one grade 3 thrombocytopenia, and no musculoskeletal effects. The median treatment duration was 57 days (range 7-560). Mean trough levels of BAY 12-9566 on day 28 ranged from 80.5 to 108.6 mg/l. Plasma trough levels were 1500-42,000-fold above the Ki's for MMP-2, MMP-3, and MMP-9 at the 800 mg p.o. b.i.d. dose level. There was no significant change in VEGF, bFGF, pyridinoline, and deoxypyridinoline crosslinks with BAY 12-9566 administration. CONCLUSIONS: The recommended dose for further testing is 800 mg p.o. b.i.d.

Redesigning nighttime care for personal care residents.

This study investigated the effects of non-disruptive nighttime care for residents in a personal care setting. The sample consisted of 18 personal care home residents in an urban, 388-bed, long-term care facility located in Winnipeg, Manitoba, Canada. The study used a quasi-experimental, single-arm design, exposing all residents to both intervention and control conditions. Independent variables were the current nighttime routine of regular rounds to turn and change residents, and a non-disruptive plan of care in which residents were checked hourly by staff and necessary care was provided when they were awake. Outcome variables included total sleep from evening bedtime to morning awakening, longest period of uninterrupted sleep at night, amount of time spent sleeping during the day, self-reported restfulness of cognitively intact residents, and skin condition. Findings suggested that the non-disruptive nighttime care routine increased total sleep by an average of 30 minutes a night for each resident. The amount of uninterrupted sleep increased by approximately 45 minutes with the new routine. No significant differences were noted in the amount of time spent sleeping during the day. There was no evidence of skin breakdown during any phase of the study. Clinical implications of this study demonstrate a need for gerontological nurses to re-evaluate nighttime care routines in personal care settings.

Venlafaxine in management of hot flashes in survivors of breast cancer: a randomised controlled trial.

BACKGROUND: Hot flashes can be troublesome, especially when hormonal therapy is contraindicated. Preliminary data have suggested that newer antidepressants, such as venlafaxine, can diminish hot flashes. We undertook a double-blind, placebo-controlled, randomised trial to assess the efficacy of venlafaxine in women with a history of breast cancer or reluctance to take hormonal treatment because of fear of breast cancer. METHODS: Participants were assigned placebo (n=56) or venlafaxine 37.5 mg daily (n=56), 75 mg daily (n=55), or 150 mg daily (n=54). After a baseline assessment week, patients took the study medication for 4 weeks. All venlafaxine treatment started at 37.5 mg daily and gradually increased in the 75 mg and 150 mg groups. Patients completed daily hot-flash questionnaire diaries. The primary endpoint was average daily hot-flash activity (number of flashes and a score combining number and severity). Analyses were based on the women who provided data throughout the baseline and study weeks. FINDINGS: 191 patients had evaluable data for the whole study period (50 placebo, 49 venlafaxine 37.5 mg, 43 venlafaxine 75 mg, 49 venlafaxine 150 mg). After week 4 of treatment, median hot flash scores were reduced from baseline by 27% (95% CI 11-34), 37% (26-54), 61% (50-68), and 61% (48-75) in the four groups. Frequencies of some side-effects (mouth dryness, decreased appetite, nausea, and constipation) were significantly higher in the venlafaxine 75 mg and 150 mg groups than in the placebo group. INTERPRETATION: Venlafaxine is an effective non-hormonal treatment for hot flashes, though the efficacy must be balanced against the drug's side-effects. Confirmation of the results of this 4-week study awaits the completion of three ongoing randomised studies to assess the effects of other related antidepressants for the treatment of hot flashes.

Long-term satisfaction and psychological and social function following bilateral prophylactic mastectomy.

CONTEXT: Prophylactic mastectomy is a preventive option for women who wish to reduce their risk of breast cancer. There has been concern about possible negative psychological sequelae following this procedure. However, few data are available regarding long-term satisfaction and psychological and social function following this procedure. OBJECTIVE: To evaluate patients' long-term satisfaction and psychological and social function following prophylactic mastectomy. DESIGN, SETTING, AND PARTICIPANTS: Descriptive study of all women known to be alive (n = 609) who had a family history of breast cancer and elected to undergo bilateral prophylactic mastectomy at a large, tertiary US health care clinic between 1960 and 1993, 94% (n = 572) of whom completed a study questionnaire. MAIN OUTCOME MEASURES: Satisfaction with procedure and effects on psychological and social function, based on responses to the study-specific questionnaire. RESULTS: Mean time from prophylactic mastectomy to last follow-up was 14.5 years. Most women (70%) were satisfied with the procedure; 11% were neutral; and 19% were dissatisfied. Among the psychological and social variables, the most striking finding was that 74% reported a diminished level of emotional concern about developing breast cancer. The majority of women reported no change/favorable effects in levels of emotional stability (68%/23%), level of stress (58%/28%), self-esteem (69%/13%), sexual relationships (73%/4%), and feelings of femininity (67%/8%). Forty-eight percent reported no change in their level of satisfaction with body appearance; 16% reported favorable effects. However, 9%, 14%, 18%, 23%, 25%, and 36% reported negative effects in these 6 variables, respectively. CONCLUSIONS: This study suggests that positive outcomes following prophylactic mastectomy include decreased emotional concern about developing breast cancer and generally favorable psychological and social outcomes. These must be weighed against the irreversibility of the decision, potential problems with implants and reconstructive surgery, and occurrence of adverse psychological and social outcomes in some women.

A Phase I trial of the farnesyl transferase inhibitor SCH66336: evidence for biological and clinical activity.

Farnesyl protein transferase (FT), an enzyme that catalyzes the first step in the posttranslational modification of ras and a number of other polypeptides, has emerged as an important target for the development of anticancer agents. SCH66336 is one of the first FT inhibitors to undergo clinical testing. We report a Phase I trial to assess the maximum tolerated dose, toxicities, and biological effectiveness of SCH66336 in inhibiting FT in vivo. Twenty patients with solid tumors received 92 courses of escalating SCH66336 doses given orally twice a day (b.i.d.) for 7 days out of every 3 weeks. Gastrointestinal toxicity (nausea, vomiting, and diarrhea) and fatigue were dose-limiting at 400 mg of SCH66336 b.i.d. Moderate reversible renal insufficiency, secondary to dehydration from gastrointestinal toxicity, was also seen. Inhibition of prelamin A farnesylation in buccal mucosa cells of patients treated with SCH66336 was demonstrated, confirming that SCH66336 inhibits protein farnesylation in vivo. One partial response was observed in a patient with previously treated metastatic non-small cell lung cancer, who remained on study for 14 months. This study not only establishes the dose for future testing on this schedule (350 mg b.i.d.) but also provides the first evidence of successful inhibition of FT in the clinical setting and the first hint of clinical activity for this class of agents.

A randomized phase II trial of two schedules of topotecan for the treatment of advanced stage non-small cell lung cancer.

We conducted a randomized phase II trial of two different schedules of topotecan in patients with advanced-stage non small lung cancer (NSCLC) without prior cytotoxic chemotherapy. All patients had histologic or cytologic confirmation of stage IV (M1) or III-B NSCLC. Patients were stratified by performance status, stage and weight loss. Patients were randomized to receive topotecan at intravenous doses of 1.5 mg/m(2)/day over 30 min for 5 days every 3 weeks (Arm A) or 1.3 mg/m(2)grade 3 in both arms included leukopenia, thrombocytopenia, malaise, constipation, diarrhea, lethargy, pulmonary, vomiting, infection and myalgia. Severe (> or = grade 3) thrombocytopenia occurred in 15.8% of Arm A patients and 37.8% of Arm B patients and this difference was statistically significant (P=0.03). The median times to progression are 101 and 63 days (P=0. 75) and the median survival times are 257 and 179 days (P=0.83) for Arms A and B, respectively. These differences in time to progression and overall survival are not statistically significant. Topotecan has limited, single agent activity in advanced NSCLC when given as 1. 5 mg/m(2)/day over 30 min for 5 days every 3 weeks. We do not intend to pursue further investigations with topotecan in patients with NSCLC.

Sex differences in fluorouracil-induced stomatitis.

PURPOSE: A meta-analysis of six North Central Cancer Treatment Group (NCCTG) trials involving patients receiving their first ever fluorouracil (5-FU)-based chemotherapy was undertaken to explore the association of sex with reports of the incidence and severity of stomatitis. PATIENTS AND METHODS: Data were obtained on a total of 731 patients (402 men and 329 women). Comparisons of incidence and severity rates and average stomatitis across sex were performed using standard binomial testing and t tests, respectively. Logistic regression analysis and a weighted analysis using data summarized to study level served as evidence of cross-validation. RESULTS: Women reported stomatitis both more often and with greater severity than did men. The incidence of any stomatitis for women was 63% versus 52% for men (P =.002). The incidence of severe or very severe stomatitis for men and women was 22% and 12%, respectively (P =. 0006). On average, women reported stomatitis of roughly 0.4 points higher than men on a 0 to 4 ordinal scale (P <.00001). Comparison of results across treatment and placebo arms was carried out to validate the initial findings. Logistic regression modelling further confirmed the results conditional on the presence of a number of potentially confounding covariates. Women were also 11% more likely than men to experience leukopenia of common toxicity criteria grade >/= 1, (70% v 59%, respectively; P <.00001) and grade 3+ (18% v 11%, respectively; P =.004). CONCLUSION: More women than men reported 5-FU-induced stomatitis. The precise mechanism resulting in different degrees of stomatitis across sex is not evident.

Evaluation of soy phytoestrogens for the treatment of hot flashes in breast cancer survivors: A North Central Cancer Treatment Group Trial.

PURPOSE: Hot flashes represent a significant clinical problem for some breast cancer survivors. Safe, effective treatment is needed for this prominent clinical problem. Although it has been shown that estrogen or progesterone replacement therapy can alleviate this problem, there are continued safety concerns regarding the use of hormonal therapies in these women. Based on anecdotal information, we hypothesized that soy-derived phytoestrogens, weak estrogen-like substances in the soybean that demonstrate estrogen agonist and/or antagonist effects when they bind to estrogen receptors, could alleviate hot flashes. This current trial was designed to investigate this hypothesis. PATIENTS AND METHODS: This double-blind clinical trial involved breast cancer survivors with substantial hot flashes. After randomization, patients underwent a 1-week baseline period with no therapy. This was followed by 4 weeks of either soy tablets or placebo. The patients then crossed over to the opposite arm in a double-blind manner for the last 4 weeks. Patients completed a daily questionnaire documenting hot flash frequency, intensity, and perceived side effects. RESULTS: Of the 177 women who were randomized and started the study substance, 155 (88%) provided useable data over the first 5 weeks; 149 provided usable data over the entire 9 weeks. There was no suggestion that the soy product was more effective in reducing hot flashes than the placebo. At study completion, patients preferred the soy product 33% of the time, the placebo 37% of the time, and neither substance 31% of the time. No toxicity was observed. CONCLUSION: The soy product did not alleviate hot flashes in breast cancer survivors.

Phase I and pharmacokinetic study of irinotecan and docetaxel in patients with advanced solid tumors: preliminary evidence of clinical activity.

PURPOSE: The goals of this study were to determine the maximum-tolerated dose and describe the toxicities of the combination of irinotecan and docetaxel administered every 3 weeks to patients with advanced malignancies and, also, to evaluate the effect of irinotecan on the disposition of docetaxel and describe preliminary evidence of antitumor activity. PATIENTS AND METHODS: Eighteen patients received 85 courses (median, two courses; range, one to 15 courses) of treatment with irinotecan, administered over 90 minutes by intravenous infusion, followed by docetaxel, administered over 60 minutes by intravenous infusion. Four escalating dose levels of irinotecan/docetaxel (160/50 mg/m(2), 160/65 mg/m(2), 200/65 mg/m(2), and 200/75 mg/m(2)) were studied. Pharmacokinetic analyses were performed to evaluate the effect of irinotecan on the disposition of docetaxel. RESULTS: The most common and dose-limiting toxicity was myelosuppression, which consisted of neutropenia that was severe (National Cancer Institute common toxicity criteria [NCI CTC] grade 4) but brief (< 5 days) in 11 patients, with three episodes of febrile neutropenia. Nonhematologic toxicities of anorexia, nausea, and stomatitis were mild to moderate (NCI CTC grades 1 and 2), but there was one incidence each of both CTC grade 3 anorexia and nausea. All patients had total alopecia. Diarrhea was dose-dependent and severe in four patients who failed to take adequate antidiarrhea therapy. Five out of 16 assessable patients, one with cholangiocarcinoma, one with leiomyosarcoma, and three with non-small-cell lung cancer, achieved partial remissions. CONCLUSION: The combination of irinotecan and docetaxel causes significant reversible myelosuppression, which was dose limiting but led to no serious sequelae. There was no evidence of a clinically significant interaction using these two agents in this sequence. The combination showed antitumor activity at all the dose levels tested and should be further studied in a number of tumor types. The recommended phase II dose on this schedule is irinotecan 160 mg/m(2) and docetaxel 65 mg/m(2).
