Impact of health-related quality of life and fatigue on survival of recurrent high-grade glioma patients.

Quality of life (QoL) impairment and fatigue are frequently experienced during treatment for recurrent high-grade glioma (HGG). Fatigue and QoL impairments can be due to primary neurological dysfunction, cytotoxic treatments, mood disturbances, and supportive medications. We now seek to understand how QoL and fatigue impacts survival in recurrent HGG. Using a prospective observational design, 237 patients with recurrent HGG and KPS ≥70 completed a self-administered questionnaire that evaluated QoL and fatigue. QoL was assessed with Functional Assessment of Cancer Therapy-General (FACT-G) and FACT-Brain (FACT-Br) scales while fatigue was assessed using Functional Assessment of Chronic Illness Therapy (FACIT-F) scale. Cox proportional hazard models were utilized to evaluate the association between QoL and fatigue and survival. Seventy-three (31 %) subjects had recurrent WHO grade III gliomas and 164 (69 %) had recurrent WHO grade IV gliomas. Median follow-up analysis was 27.60 months. In univariate Cox analyses, the FACT-Br specific subscale (HR 0.88; CI 95 %, 0.77-1; p = 0.048) and FACIT-F (HR 0.82; CI 95 %, 0.68-0.99; p = 0.045) were both significant predictors of survival. Fatigue added prognostic information beyond that provided by KPS, age, sex, tumor grade, and number of prior progressions (HR 0.80; CI 95 %, 0.68-0.9; p = 0.031). A greater degree of fatigue was associated with poorer survival in recurrent HGG patients. In multivariable analyses, FACT-G and FACT-Br are not independent predictors of prognosis. Fatigue is a strong independent predictor of survival that provides incremental prognostic value to the traditional markers of prognosis in recurrent HGG. Pharmacological or non-pharmacological strategies to treat fatigue warrant investigation.

Unmet spiritual care needs impact emotional and spiritual well-being in advanced cancer patients.

PURPOSE: Spiritual care is an important part of healthcare, especially when facing the crisis of advanced cancer. Do oncology inpatients receive spiritual care consistent with their needs? When inconsistent, are there deleterious effects on patient outcomes? METHODS: Patients with advanced cancer (N = 150) were surveyed during their inpatient stay at a southeastern medical center using validated instruments documenting spirituality, quality of life, mood, and satisfaction with care. Relationships between the receipt of less spiritual care than desired and patient outcomes were examined. RESULTS: Almost all patients had spiritual needs (91%) and the majority desired and received spiritual care from their healthcare providers (67%; 68%), religious community (78%; 73%), and hospital chaplain (45%; 36%). However, a significant subset received less spiritual care than desired from their healthcare providers (17%), religious community (11%), and chaplain (40%); in absolute terms, the number who received less care than desired from one or more sources was substantial (42 of 150). Attention to spiritual care would improve satisfaction with care while hospitalized for 35% of patients. Patients who received less spiritual care than desired reported more depressive symptoms [adjusted ß (SE) = 1.2 (0.47), p = 0.013] and less meaning and peace [adjusted ß (SE) = -2.37 (1.15), p = 0.042]. CONCLUSIONS: A substantial minority of patients did not receive the spiritual care they desired while hospitalized. When spiritual needs are not met, patients are at risk of depression and reduced sense of spiritual meaning and peace. Spiritual care should be matched to cancer patients' needs.

A phase I trial of the farnesyl transferase inhibitor, SCH 66336, with temozolomide for patients with malignant glioma.

We conducted a phase I clinical trial of the combination of SCH 66336 with temozolomide administered on the standard 5-day dosing schedule. The primary objective was to determine the maximum tolerated dose and dose limiting toxicity (DLT) of twice daily SCH 66336 when administered with temozolomide to adults with malignant glioma previously treated with radiation therapy. Patients were enrolled to two strata: stratum A, patients not on enzyme-inducing antiepileptic drugs (EIAEDs); stratum B, patients receiving EIAEDs. Temozolomide was administered at a dose of 150 mg/m(2) daily for five days for the first 28-day cycle and escalated to 200 mg/m(2), during subsequent cycles. SCH 66336 was administered twice daily on a continuous daily dosing schedule. The starting dose of SCH 66336 was 75 mg twice daily for stratum A and 125 mg twice daily for stratum B. Cohorts of 3-6 patients were treated per dose level until DLT was observed. Thirty six patients were enrolled on study, including 21 patients on stratum A and 15 on stratum B. All DLTs were grade 3 events and included hepatic, gastrointestinal, renal, thrombotic and constitutional events. No grade 4 or 5 toxicities were observed. The phase II dose of SCH 66336 when combined with temozolomide is 150 mg twice daily for patients not on EIAEDs and 175 mg twice daily for patients on EIAEDs.

Effects of a high daily dose of soy isoflavones on DNA damage, apoptosis, and estrogenic outcomes in healthy postmenopausal women: a phase I clinical trial.

OBJECTIVE: A phase I double-blind clinical trial was conducted to evaluate the effects of a high oral dose of soy isoflavones administered daily for 84 days to healthy postmenopausal women. Principal outcome measures included DNA damage, apoptosis, and changes indicative of estrogenic stimulation. DESIGN: After eligibility and equol-producer status were determined, stratified randomization was used to assign women to the isoflavone (active) or placebo group. Of the 30 women who completed the study, 18 were in the active group. DNA damage was assessed via COMET and apurinic/apyrimidinic site assays in lymphocytes. Apoptosis was evaluated via terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling and activated caspase-3 assays in lymphocytes. Estrogenic/antiestrogenic effects were assessed using a self-report questionnaire and by assaying for estrogen, follicle-stimulating hormone, luteinizing hormone, and sex hormone-binding globulin in blood. RESULTS: In treated postmenopausal women, there was no indication that high doses of soy isoflavones caused DNA strand breakage, increased apurinic/apyrimidinic sites, or increased apoptosis in peripheral lymphocytes. There were no significant changes in mean values for estrogenic effects or other laboratory measurements. Very few adverse events occurred, and the only drug-related adverse events were mild or grade 1 in severity. CONCLUSIONS: Unconjugated soy isoflavones appear to be safe and well tolerated in healthy postmenopausal women at doses of 900 mg/day.

Cardiopulmonary function and age-related decline across the breast cancer survivorship continuum.

PURPOSE: To evaluate cardiopulmonary function (as measured by peak oxygen consumption [VO(2peak)]) across the breast cancer continuum and its prognostic significance in women with metastatic disease. PATIENTS AND METHODS: Patients with breast cancer representing four cross-sectional cohorts--that is, (1) before, (2) during, and (3) after adjuvant therapy for nonmetastatic disease, and (4) during therapy in metastatic disease--were studied. A cardiopulmonary exercise test (CPET) with expired gas analysis was used to assess VO(2peak). A Cox proportional hazards model was used to estimate the risk of death according to VO(2peak) category (< 15.4 v ≥ 15.4 mL · kg(-1) · min(-1)) with adjustment for clinical factors. RESULTS: A total of 248 women (age, 55 ± 8 years) completed a CPET. Mean VO(2peak) was 17.8 ± a standard deviation of 4.3 mL · kg(-1) · min(-1), the equivalent of 27% ± 17% below age-matched healthy sedentary women. For the entire cohort, 32% had a VO(2peak) less than 15.4 mL · kg(-1) · min(-1)--the VO(2peak) required for functional independence. VO(2peak) was significantly different across breast cancer cohorts for relative (mL · kg(-1) · min(-1)) and absolute (L · min(-1)) VO(2peak) (P = .017 and P < .001, respectively); VO(2peak) was lowest in women with metastatic disease. In patients with metastatic disease (n = 52), compared with patients achieving a VO(2peak) ≤ 1.09 L · min(-1), the adjusted hazard ratio for death was 0.32 (95% CI, 0.16 to 0.67, P = .002) for a VO(2peak) more than 1.09 L · min(-1). CONCLUSION: Patients with breast cancer have marked impairment in VO(2peak) across the entire survivorship continuum. VO(2peak) may be an independent predictor of survival in metastatic disease.

Exercise behavior, functional capacity, and survival in adults with malignant recurrent glioma.

PURPOSE: Identifying strong markers of prognosis are critical to optimize treatment and survival outcomes in patients with malignant recurrent glioma. We investigated the prognostic significance of exercise behavior and functional capacity in this population. PATIENTS AND METHODS: Using a prospective design, 243 patients with WHO grades 3 to 4 recurrent malignant glioma and Karnofsky performance status (KPS) ≥ 70 completed a self-administered questionnaire that assessed exercise behavior and performed a 6-minute walk test (6MWT) to assess functional capacity. Cox proportional models were used to estimate the risk of all-cause mortality according to 6MWT distance (6MWD; < 390 meters, 390-489 meters, > 489 meters) and exercise behavior (metabolic equivalent [MET] -h/wk) adjusted for KPS and other important clinical factors. RESULTS: Median follow-up was 27.43 months. During this period, 149 deaths were recorded (61% of the total sample). Exercise behavior was an independent predictor of survival (P = .0081). Median survival was 13.03 months for patients reporting < 9 MET-h/wk relative to 21.84 months for those reporting ≥ 9 MET-h/wk. Exercise behavior added incremental prognostic value beyond that provided by KPS, age, sex, grade, and number of prior progressions (P < .001). Compared with patients reporting < 9 MET-h/wk, the adjusted hazard ratio for mortality was 0.64 (95% CI, 0.46 to 0.91) for patients reporting ≥ 9 MET-h/wk. Functional capacity was not an independent predictor of prognosis. CONCLUSION: Exercise behavior is a strong independent predictor of survival that provides incremental prognostic value to KPS as well as traditional markers of prognosis in malignant recurrent glioma.

Prognostic value of fluorine-18 fluorodeoxyglucose positron emission tomography imaging in patients with advanced-stage non-small-cell lung carcinoma.

PURPOSE: To determine whether the amount of fluorine-18 fluorodeoxyglucose (FDG) uptake in the primary lung cancer on positron emission tomography (PET) imaging at the time of presentation has prognostic significance in patients with advanced-stage non-small-cell lung cancer (NSCLC). PATIENTS AND METHODS: A retrospective review identified 214 patients with advanced-stage NSCLC (stage IIIA, IIIB, and IV) who underwent FDG PET study at the time of diagnosis. Extensive clinical data, including tumor histologic cell type, pathologic stage at presentation, and treatment, were recorded. The maximum standardized uptake value (SUV(max)) in the primary tumor on FDG PET on survival was examined using Cox proportional hazards regression. RESULTS: One hundred fifty-eight (74%) of the 214 patients died and 56 patients were reported alive at 27 months (range, 3 to 140 months) after the diagnosis of NSCLC. Using the median SUV(max) of 11.1, the patient population was subdivided. The median survival of the 106 patients with the primary tumor having an SUV(max) less than 11.1 was 16 months (95% CI, 12 to 21 months), whereas the median survival of the 108 patients with the primary tumor having an SUV(max) > or = 11.1 was 12 months (95% CI, 10 to 15 months). Univariate and multivariate analysis did not provide evidence that survival for patient subgroups defined by the median SUV(max) were significantly different (univariate P = .11; multivariate P = .45). CONCLUSION: FDG uptake of the primary lesions in patients with a new diagnosis of advanced-stage NSCLC does not have a significant relationship with survival.
