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 ...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.
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).
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.
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
β
(SE) = 1.2 (0.47),
p
= 0.013 and less meaning and peace adjusted
β
(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.
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.
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.
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.
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.
Abstract
Background. To evaluate the safety and efficacy of moderate-to-high intensity aerobic training in breast cancer patients receiving neoadjuvant chemotherapy. Methods. Twenty patients with ...stage IIB-IIIC operable breast cancer were randomly assigned to receive doxorubicin plus cyclophosphamide (AC) or AC in combination with aerobic training (AC + AET) (n = 10/group) for 12 weeks. The AC+ AET group performed three supervised aerobic cycle ergometry sessions per week at 60%-100% of exercise capacity (VO2peak). Safety outcomes included exercise testing as well as treatment- and exercise training-related adverse events (AEs), whereas efficacy outcomes included cardiopulmonary function and patient-reported outcomes (PROs) as measured by a cardiopulmonary exercise test (CPET) and Functional Assessment of Cancer Therapy-Breast (FACT-B) scale. Results. Twelve non-significant ECG abnormalities and three non-life threatening events occurred during CPET procedures. One AE was reported during aerobic training. There were no significant between group differences for clinician-documented events (e.g. pain, nausea) or hematological parameters (p's > 0.05). Attendance and adherence rates to aerobic training were 82% and 66%, respectively. Intention-to-treat analysis indicated that VO2peak increased by 2.6 ± 3.5 ml/kg/min (+ 13.3%) in the AC + AET group and decreased by 1.5 ± 2.2 ml/kg/min (−8.6%) in the AC group (between group difference, p = 0.001). FACT-B increased 11.1 points in the AC + AET group compared to a 1.5 point decrease in the AC group (between group difference, p = 0.685). Conclusion. Moderate-to-high intensity aerobic training when conducted with one-on-one supervision is a safe adjunct therapy associated with improvements in cardiopulmonary function and select PROs during neoadjuvant chemotherapy.
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).
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.
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).
FDG uptake of the primary lesions in patients with a new diagnosis of advanced-stage NSCLC does not have a significant relationship with survival.
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.
Preclinical studies in mice have demonstrated that the prophylactic depletion of immunosuppressive regulatory T-cells (T(Regs)) through targeting the high affinity interleukin-2 (IL-2) receptor ...(IL-2Rα/CD25) can enhance anti-tumor immunotherapy. However, therapeutic approaches are complicated by the inadvertent inhibition of IL-2Rα expressing anti-tumor effector T-cells.
To determine if changes in the cytokine milieu during lymphopenia may engender differential signaling requirements that would enable unarmed anti-IL-2Rα monoclonal antibody (MAbs) to selectively deplete T(Regs) while permitting vaccine-stimulated immune responses.
A randomized placebo-controlled pilot study was undertaken to examine the ability of the anti-IL-2Rα MAb daclizumab, given at the time of epidermal growth factor receptor variant III (EGFRvIII) targeted peptide vaccination, to safely and selectively deplete T(Regs) in patients with glioblastoma (GBM) treated with lymphodepleting temozolomide (TMZ).
Daclizumab treatment (n = 3) was well-tolerated with no symptoms of autoimmune toxicity and resulted in a significant reduction in the frequency of circulating CD4+Foxp3+ TRegs in comparison to saline controls (n = 3)( p = 0.0464). A significant (p<0.0001) inverse correlation between the frequency of TRegs and the level of EGFRvIII specific humoral responses suggests the depletion of TRegs may be linked to increased vaccine-stimulated humoral immunity. These data suggest this approach deserves further study.

Abstract Context The Patient Care Monitor (PCM) is a review of systems survey delivered by means of an electronic patient-reported outcomes (ePRO) data capture system that uses wireless tablet ...computers. Although the PCM 1.0 is validated, the updated PCM 2.0 has not been validated nor tested in the academic setting. Objectives To validate and test the PCM 2.0 in three cancer populations. Methods Two hundred seventy-five individuals participated in three clinical trials enrolling breast ( n = 65), gastrointestinal ( n = 113), and lung ( n = 97) cancer patients. Internal consistency was evaluated using Cronbach's alpha coefficients calculated for six PCM subscales (general physical symptoms, treatment side effects, distress, despair, impaired performance, and impaired ambulation) and a Quality-of-Life Index. Construct validity was evaluated through Pearson's correlation between PCM subscales and subscales of the Functional Assessment of Cancer Therapy—General (FACT-G), the M.D. Anderson Symptom Inventory (MDASI), and the Functional Assessment of Chronic Illness Therapy—Fatigue (FACIT-F). The participants had the following characteristics: mean age was 58 years (standard deviation: 11), 52% were females, 79% were whites, 17% were blacks, 62% had no college degree, and 78% had metastatic or recurrent disease. Results Raw and normalized scores for PCM 2.0 subscales were internally consistent across study cohorts. PCM 2.0 subscales correlated significantly ( P < 0.05) with the corresponding subscales on FACT-G, MDASI, and FACIT-F, with the exception of FACT-G social well-being, particularly for the lung cancer population. These correlations demonstrated construct validity. PCM 2.0 results followed expected patterns by cancer etiology. Prior reports demonstrate patient satisfaction with PCM 2.0. Conclusion Within three unique academic oncology populations, PCM 2.0 is a valid ePRO instrument for assessing symptoms with seven patient-centered subscale or index domains.
