Self-rated health supersedes patient satisfaction with service quality as a predictor of survival in prostate cancer.

BACKGROUND: We have previously reported that higher patient satisfaction (PS) with service quality is associated with favorable survival outcomes in a variety of cancers. However, we argued that patients with greater satisfaction might be the ones with better self-rated health (SRH), a recognized predictor of cancer survival. We therefore investigated whether SRH can supersede patient satisfaction as a predictor of survival in prostate cancer. METHODS: Nine hundred seventeen prostate cancer treated at four Cancer Treatment Centers of America(®) hospitals between July 2011 and March 2013. PS was measured on a 7-point scale ranging from "completely dissatisfied" to "completely satisfied". SRH was measured on a 7-point scale ranging from "very poor" to "excellent". Both were dichotomized into two categories: top box response (7) versus all others (1-6). Patient survival was the primary end point. Cox regression was used to evaluate the association between PS and survival controlling for covariates. RESULTS: The response rate for this study was 72%. Majority of patients (n = 517) had stage II disease. Seven hundred eighty-seven (85.8%) patients were "completely satisfied". Three hundred nineteen (34.8%) patients had "excellent" SRH. There was a weak but significant correlation between satisfaction and SRH (Kendall's tau b = 0.18; p < 0.001). On univariate analysis, "completely satisfied" patients had a significantly lower risk of mortality (HR = 0.46; 95% CI: 0.25-0.85; p = 0.01). Similarly, patients with "excellent" SRH had a significantly lower risk of mortality (HR = 0.25; 95% CI: 0.11-0.58; p = 0.001). On multivariate analysis, SRH was found to be a significant predictor of survival (HR = 0.31; 95% CI: 0.12-0.79; p = 0.01) while patient satisfaction was not (HR = 0.76; 95% CI: 0.40-1.5; p = 0.40). CONCLUSIONS: SRH supersedes patient satisfaction with service quality as a predictor of survival in prostate cancer. SRH should be used as a control variable in analyses involving patient satisfaction as a predictor of clinical cancer outcomes.

The Relationship between Patient Satisfaction with Service Quality and Survival in Non-Small Cell Lung Cancer - Is Self-Rated Health a Potential Confounder?

BACKGROUND/AIMS: Previously we reported that higher patient satisfaction (PS) with service quality is associated with favorable survival outcomes in a variety of cancers. However, we cautioned the readers that patients with greater satisfaction might be the ones with better self-rated health (SRH), a well-established prognosticator of cancer survival. In other words, SRH could potentially confound the PS and survival relationship. We investigated this hypothesis in non-small cell lung cancer (NSCLC). METHODS: 778 NSCLC patients (327 males and 451 females; mean age 58.8 years) treated at 4 Cancer Treatment Centers of America hospitals between July 2011 and March 2013. PS was measured on a 7-point scale ranging from "completely dissatisfied" to "completely satisfied". SRH was measured on a 7-point scale ranging from "very poor" to "excellent". Both were dichotomized into 2 categories: top box response (7) versus all others (1-6). Patient survival was the primary end point. Cox regression was used to evaluate the association between PS and survival controlling for covariates. RESULTS: 74, 70, 232 and 391 patients had stage I, II, III and IV disease respectively. 631 (81.1%) patients were "completely satisfied". 184 (23.7%) patients had "excellent" SRH. There was a weak but significant correlation between overall PS and SRH (Kendall's tau b = 0.19; p<0.001). On univariate analysis, "completely satisfied" patients had a significantly lower risk of mortality (HR = 0.75; 95% CI: 0.57 to 0.99; p = 0.04). Similarly, patients with "excellent" SRH had a significantly lower risk of mortality (HR = 0.61; 95% CI: 0.46 to 0.81; p = 0.001). On multivariate analysis controlling for stage at diagnosis, treatment history and gender, SRH was found to be a significant predictor of survival (HR = 0.67; 95% CI: 0.50 to 0.89; p = 0.007) while PS was not (HR = 0.86; 95% CI: 0.64 to 1.2; p = 0.32). Among the individual PS items, the only significant independent predictor of survival was "teams communicating with each other concerning your medical condition and treatment" (HR = 0.59; 95% CI: 0.36 to 0.94; p = 0.03). CONCLUSION: SRH appears to confound the PS-survival relationship in NSCLC. SRH should be used as a control/stratification variable in analyses involving PS as a predictor of clinical cancer outcomes.

Patient satisfaction with service quality as a predictor of survival outcomes in breast cancer.

PURPOSE: Despite the recognized relevance of symptom burden in breast cancer, there has been limited exploration of whether an individual patient's assessment of the overall quality of care received might influence outcome. We therefore evaluated the relationship between patient-reported satisfaction with service quality and survival in breast cancer. METHODS: A random sample of 1,521 breast cancer patients treated at Cancer Treatment Centers of America. A questionnaire which covered several dimensions of patient satisfaction was administered. Items were measured on a seven-point Likert scale ranging from "completely dissatisfied" to "completely satisfied". Univariate and multivariate Cox regression was used to evaluate the association between patient satisfaction and survival. RESULTS: Of 1,521 patients, 836 were newly diagnosed, and 685 had previously been treated. A number of 409, 611, 323, and 178 patients had stage I, II, III, and IV disease, respectively. A total of 1,106 (72.7 %) patients were completely satisfied with the overall service quality, while 415 (27.3 %) were not. On univariate analysis, completely satisfied patients had a significantly lower risk of mortality compared to those not completely satisfied (HR = 0.62; 95 % CI 0.50-0.76; p < 0.001). On multivariate analysis, completely satisfied patients demonstrated significantly lower mortality (HR = 0.71; 95 % CI 0.57-0.87; p = 0.001) compared to those not completely satisfied. CONCLUSIONS: Patient satisfaction with service quality was an independent predictor of survival in breast cancer. Further exploration of a possible meaningful relationship between patient satisfaction with the care they receive and outcomes in breast cancer is indicated.

Patient satisfaction with service quality in an oncology setting: implications for prognosis in non-small cell lung cancer.

OBJECTIVE: To evaluate the relationship between self-reported satisfaction with service quality and overall survival in non-small cell lung cancer (NSCLC). DESIGN: A prospective cohort study. SETTING: Cancer Treatment Centers of America(®) from July 2007 and December 2010. PARTICIPANTS: Nine hundred and eighty-six returning NSCLC patients. INTERVENTION: Overall patient experience 'considering everything, how satisfied are you with your overall experience' was measured on a 7-point Likert scale ranging from 'completely dissatisfied' to 'completely satisfied.'. MAIN OUTCOME MEASURE: Patient survival was the primary end point. RESULTS: The response rate for this study was 69%. Six hundred patients were newly diagnosed, while 386 were previously treated. Four hundred sixty-nine were males, while 517 were females. 101, 59, 288 and 538 patients had stage I, II, III and IV disease, respectively. Mean age was 58.9 years. Six hundred and thirty (63.9%) patients had expired at the time of this analysis. Seven hundred and sixty-two (77.3%) patients were 'completely satisfied'. Median overall survival was 12.1 months (95% confidence interval (CI): 10.9-13.2 months). On univariate analysis, 'completely satisfied' patients had a significantly lower risk of mortality compared with those not 'completely satisfied' [hazard ratio (HR) = 0.70; 95% CI: 0.59-0.84; P < 0.001]. On multivariate analysis controlling for stage at diagnosis, prior treatment history, age and gender, 'completely satisfied' patients demonstrated significantly lower mortality (HR = 0.71; 95% CI: 0.60-0.85; P < 0.001) compared with those not 'completely satisfied'. CONCLUSIONS: Self-reported experience with service quality was an independent predictor of survival in NSCLC patients undergoing oncologic treatment, a novel finding in the literature. Based on these provocative findings, further exploration of this relationship is warranted in well-designed prospective studies.

Phase I clinical trial to evaluate the safety, tolerability, and pharmacokinetics of high-dose intravenous ascorbic acid in patients with advanced cancer.

PURPOSE: This phase I clinical trial evaluated the safety, tolerability, and pharmacokinetics of high-dose intravenous (i.v.) ascorbic acid as a monotherapy in patients with advanced solid tumors refractory to standard therapy. METHODS: Five cohorts of three patients received i.v. ascorbic acid administered at 1 g/min for 4 consecutive days/week for 4 weeks, starting at 30 g/m² in the first cohort. For subsequent cohorts, dose was increased by 20 g/m² until a maximum tolerated dose was found. RESULTS: Ascorbic acid was eliminated by simple first-order kinetics. Half-life and clearance values were similar for all patients of all cohorts (2.0 ± 0.6 h, 21 ± 5 dL/h m², respectively). C(max) and AUC values increased proportionately with dose between 0 and 70 g/m², but appeared to reach maximal values at 70 g/m² (49 mM and 220 h mM, respectively). Doses of 70, 90, and 110 g/m² maintained levels at or above 10-20 mM for 5-6 h. All doses were well tolerated. No patient demonstrated an objective antitumor response. CONCLUSIONS: Ascorbic acid administered i.v. at 1 g/min for 4 consecutive days/week for 4 weeks produced up to 49 mM ascorbic acid in patient's blood and was well tolerated. The recommended dose for future studies is 70-80 g/m².

Can patient experience with service quality predict survival in colorectal cancer?

Despite the recognized relevance of symptom burden in colorectal cancer, there has been limited exploration of whether an individual patient's assessment of the overall quality-of-care received might influence outcome. We evaluated the relationship between patient-reported experience with service quality and survival in 702 returning colorectal cancer patients treated at our institution between July 2007 and December 2010. Overall patient experience "considering everything, how satisfied are you with your overall experience?" was measured on a 7-point Likert scale ranging from completely dissatisfied to completely satisfied. It was dichotomized into two categories: top box response (7) versus all others (1-6). Cox regression was used to evaluate the association between patient experience and survival. Of 702 patients, 506 were "completely satisfied" while 196 were not. On univariate analysis, "completely satisfied" patients had a significantly lower risk of mortality compared to those "not completely satisfied" (hazard ratio [HR] = 0.78; 95% confidence interval [CI]: 0.61-0.98; p = .04). Similarly, on multivariate analysis controlling for stage at diagnosis, treatment history, age, and gender, "completely satisfied" patients demonstrated significantly lower mortality (HR = 0.74; 95% CI: 0.58-0.95; p = .02). Patient experience with service quality was an independent predictor of survival in colorectal cancer, a novel finding in the literature.

The relationship between patient satisfaction with service quality and survival in pancreatic cancer.

PURPOSE: Despite the recognized relevance of symptom burden in pancreatic cancer, there has been limited exploration of whether an individual patient's satisfaction with the overall quality of care received might influence outcome. We evaluated the relationship between patient satisfaction with health service quality and survival in patients with pancreatic cancer. PATIENTS AND METHODS: A random sample of 496 pancreatic cancer patients treated at Cancer Treatment Centers of America(®) (CTCA) between July 2007 and December 2010. A questionnaire that covered several dimensions of patient satisfaction was administered. Items were measured on a seven-point Likert scale ranging from "completely dissatisfied" to "completely satisfied." Patient survival was the primary end point. Cox regression was used to evaluate the association between patient satisfaction and survival. RESULTS: The response rate for this study was 72%. Of the 496 patients, 345 (69.6%) reported being "completely satisfied" with the care provided. Median overall survival was 7.9 months. On univariate analysis, patients reporting they were "completely satisfied" experienced superior survival compared with patients stating they were "not completely satisfied" (hazard ratio = 0.62; 95% confidence interval: 0.50-0.77; P < 0.001). On multivariate analysis controlling for stage at diagnosis, treatment history, and specific CTCA treatment center, "completely satisfied" patients demonstrated significantly lower mortality (hazard ratio = 0.63; 95% confidence interval: 0.51-0.79; P < 0.001). CONCLUSION: In this exploratory analysis, patient satisfaction with health service quality was an independent predictor of survival in pancreatic cancer. Further exploration of a possible meaningful relationship between patient satisfaction with the care they have received and outcome in this difficult malignancy is indicated.

Beliefs and perceptions of women with newly diagnosed breast cancer who refused conventional treatment in favor of alternative therapies.

PURPOSE: Although breast cancer is a highly treatable disease, some women reject conventional treatment opting for unproven "alternative therapy" that may contribute to poor health outcomes. This study sought to understand why some women make this decision and to identify messages that might lead to greater acceptance of evidence-based treatment. PATIENTS AND METHODS: This study explored treatment decision making through in-depth interviews with 60 breast cancer patients identified by their treating oncologists. Thirty refused some or all conventional treatment, opting for alternative therapies, whereas 30 accepted both conventional and alternative treatments. All completed the Beck Anxiety Inventory and the Rotter Locus of Control scale. RESULTS: Negative first experiences with "uncaring, insensitive, and unnecessarily harsh" oncologists, fear of side effects, and belief in the efficacy of alternative therapies were key factors in the decision to reject potentially life-prolonging conventional therapy. Refusers differed from controls in their perceptions of the value of conventional treatment, believing that chemotherapy and radiotherapy were riskier (p < .0073) and less beneficial (p < .0001) than did controls. Controls perceived alternative medicine alone as riskier than did refusers because its value for treating cancer is unproven (p < .0001). Refusers believed they could heal themselves naturally from cancer with simple holistic methods like raw fruits, vegetables, and supplements. CONCLUSION: According to interviewees, a compassionate approach to cancer care plus physicians who acknowledge their fears, communicate hope, educate them about their options, and allow them time to come to terms with their diagnosis before starting treatment might have led them to better treatment choices.

Role of nutritional status in predicting quality of life outcomes in cancer--a systematic review of the epidemiological literature.

Malnutrition is a significant factor in predicting cancer patients' quality of life (QoL). We systematically reviewed the literature on the role of nutritional status in predicting QoL in cancer. We searched MEDLINE database using the terms "nutritional status" in combination with "quality of life" together with "cancer". Human studies published in English, having nutritional status as one of the predictor variables, and QoL as one of the outcome measures were included. Of the 26 included studies, 6 investigated head and neck cancer, 8 gastrointestinal, 1 lung, 1 gynecologic and 10 heterogeneous cancers. 24 studies concluded that better nutritional status was associated with better QoL, 1 study showed that better nutritional status was associated with better QoL only in high-risk patients, while 1 study concluded that there was no association between nutritional status and QoL. Nutritional status is a strong predictor of QoL in cancer patients. We recommend that more providers implement the American Society of Parenteral and Enteral Nutrition (ASPEN) guidelines for oncology patients, which includes nutritional screening, nutritional assessment and intervention as appropriate. Correcting malnutrition may improve QoL in cancer patients, an important outcome of interest to cancer patients, their caregivers, and families.

The association of quality of life with potentially remediable disruptions of circadian sleep/activity rhythms in patients with advanced lung cancer.

BACKGROUND: Cancer patients routinely develop symptoms consistent with profound circadian disruption, which causes circadian disruption diminished quality of life. This study was initiated to determine the relationship between the severity of potentially remediable cancer-associated circadian disruption and quality of life among patients with advanced lung cancer. METHODS: We concurrently investigated the relationship between the circadian rhythms of 84 advanced lung cancer patients and their quality of life outcomes as measured by the EORTC QLQ C30 and Ferrans and Powers QLI. The robustness and stability of activity/sleep circadian daily rhythms were measured by actigraphy. Fifty three of the patients in the study were starting their definitive therapy following diagnosis and thirty one patients were beginning second-line therapy. Among the patients who failed prior therapy, the median time between completing definitive therapy and baseline actigraphy was 4.3 months, (interquartile range 2.1 to 9.8 months). RESULTS: We found that circadian disruption is universal and severe among these patients compared to non-cancer-bearing individuals. We found that each of these patient's EORTC QLQ C30 domain scores revealed a compromised capacity to perform the routine activities of daily life. The severity of several, but not all, EORTC QLQ C30 symptom items correlate strongly with the degree of individual circadian disruption. In addition, the scores of all four Ferrans/Powers QLI domains correlate strongly with the degree of circadian disruption. Although Ferrans/Powers QLI domain scores show that cancer and its treatment spared these patients' emotional and psychological health, the QLI Health/Function domain score revealed high levels of patients' dissatisfaction with their health which is much worse when circadian disruption is severe. Circadian disruption selectively affects specific Quality of Life domains, such as the Ferrans/Powers Health/Function domain, and not others, such as EORTC QLQ C30 Physical Domain. CONCLUSIONS: These data suggest the testable possibility that behavioral, hormonal and/or light-based strategies to improve circadian organization may help patients suffering from advanced lung cancer to feel and function better.

Validation of actigraphy to assess circadian organization and sleep quality in patients with advanced lung cancer.

BACKGROUND: Many cancer patients report poor sleep quality, despite having adequate time and opportunity for sleep. Satisfying sleep is dependent on a healthy circadian time structure and the circadian patterns among cancer patients are quite abnormal. Wrist actigraphy has been validated with concurrent polysomnography as a reliable tool to objectively measure many standard sleep parameters, as well as daily activity. Actigraphic and subjective sleep data are in agreement when determining activity-sleep patterns and sleep quality/quantity, each of which are severely affected in cancer patients. We investigated the relationship between actigraphic measurement of circadian organization and self-reported subjective sleep quality among patients with advanced lung cancer. METHODS: This cross-sectional and case control study was conducted in 84 patients with advanced non-small cell lung cancer in a hospital setting for the patients at Midwestern Regional Medical Center (MRMC), Zion, IL, USA and home setting for the patients at WJB Dorn Veterans Affairs Medical Center (VAMC), Columbia, SC, USA. Prior to chemotherapy treatment, each patient's sleep-activity cycle was measured by actigraphy over a 4-7 day period and sleep quality was assessed using the Pittsburgh Sleep Quality Index (PSQI) questionnaire. RESULTS: The mean age of our patients was 62 years. 65 patients were males while 19 were females. 31 patients had failed prior treatment while 52 were newly diagnosed. Actigraphy and PSQI scores showed significantly disturbed daily sleep-activity cycles and poorer sleep quality in lung cancer patients compared to healthy controls. Nearly all actigraphic parameters strongly correlated with PSQI self-reported sleep quality of inpatients and outpatients. CONCLUSIONS: The correlation of daily activity/sleep time with PSQI-documented sleep indicates that actigraphy can be used as an objective tool and/or to complement subjective assessments of sleep quality in patients with advanced lung cancer. These results suggest that improvements to circadian function may also improve sleep quality.

The relationship between perceived service quality and patient willingness to recommend at a national oncology hospital network.

BACKGROUND: "Willingness to recommend" questions are being increasingly used to measure and manage patient loyalty. Yet, there is little data in the literature correlating the "willingness to recommend" question with commonly used perceived service quality items in surveys to identify the key drivers of the optimal patient experience. We therefore evaluated the relationship between perceived service quality and subsequent single top box "willingness to recommend" scores among oncology patients. METHODS: A total of 2018 returning cancer patients treated at Cancer Treatment Centers of America® (CTCA) responded to an internally developed service quality questionnaire, which covered the following dimensions: operations and services, treatment and care with a multidisciplinary team and patient endorsements. Items were measured on a 7-point Likert-type scale ranging from "completely dissatisfied" to "completely satisfied." Patient willingness to, "recommend this facility to friends and associates" was measured on an 11-point scale ranging from "not at all likely" to "extremely likely", which was subsequently dichotomized into two categories: top box response (10) versus all others (0-9). The relationship between perceived service quality and "willingness to recommend" was assessed via Kendall's tau b correlation and univariate and multivariate logistic regression. RESULTS: Of the 2018 patients, 959 were newly diagnosed while 1059 were previously treated. 902 were males and 1116 females. The mean age was 54.2 years and the most frequent diagnoses were breast (412), lung (294), prostate (260), colorectal (179) and pancreas (169). 1553 patients said they were "extremely likely" to recommend CTCA to friends and associates, resulting in 77% "top box" responses while 465 (23%) responded in all other categories. The key service quality drivers that were statistically significant in the final logistic model were "team helping you understand your medical condition", "staff genuinely caring for you as an individual", "whole person approach to patient care" and "CTCA medical oncologist." CONCLUSIONS: In this multi-center study, we demonstrate the predictive significance of perceived service quality as it relates to patient willingness to recommend an oncology service provider. This study is unique in reporting on the role of perceived service quality as a predictor of patient willingness to recommend in a large sample of cancer patients.

Prevalence of serum vitamin D deficiency and insufficiency in cancer: Review of the epidemiological literature.

Vitamin D deficiency has been found to be associated with a variety of cancers, including prostate, multiple myeloma, colorectal and breast cancer. Several studies have shown vitamin D levels to have an inverse relation with cancer mortality, while others have considered it a potential risk factor. Vitamin D is believed to influence cancer prevalence, risk and survival; hence the need to assess vitamin D levels in cancer. Although numerous studies have been conducted to demonstrate vitamin D deficiency as a risk factor for cancer, relatively few have studied its prevalence. Moreover, studies estimating prevalence differ from each other, with respect to study population, sample size, study design, definition of vitamin D deficiency used and method of vitamin D assessment (with most studies limited to one particular type of cancer with relatively small sample sizes). Therefore, we qualitatively reviewed the epidemiological evidence in the oncology literature on the prevalence of vitamin D deficiency and insufficiency as measured by serum vitamin D concentrations.

Pretreatment serum albumin as a predictor of cancer survival: a systematic review of the epidemiological literature.

BACKGROUND: There are several methods of assessing nutritional status in cancer of which serum albumin is one of the most commonly used. In recent years, the role of malnutrition as a predictor of survival in cancer has received considerable attention. As a result, it is reasonable to investigate whether serum albumin has utility as a prognostic indicator of cancer survival in cancer. This review summarizes all available epidemiological literature on the association between pretreatment serum albumin levels and survival in different types of cancer. METHODS: A systematic search of the literature using the MEDLINE database (January 1995 through June 2010) to identify epidemiologic studies on the relationship between serum albumin and cancer survival. To be included in the review, a study must have: been published in English, reported on data collected in humans with any type of cancer, had serum albumin as one of the or only predicting factor, had survival as one of the outcome measures (primary or secondary) and had any of the following study designs (case-control, cohort, cross-sectional, case-series prospective, retrospective, nested case-control, ecologic, clinical trial, meta-analysis). RESULTS: Of the 29 studies reviewed on cancers of the gastrointestinal tract, all except three found higher serum albumin levels to be associated with better survival in multivariate analysis. Of the 10 studies reviewed on lung cancer, all excepting one found higher serum albumin levels to be associated with better survival. In 6 studies reviewed on female cancers and multiple cancers each, lower levels of serum albumin were associated with poor survival. Finally, in all 8 studies reviewed on patients with other cancer sites, lower levels of serum albumin were associated with poor survival. CONCLUSIONS: Pretreatment serum albumin levels provide useful prognostic significance in cancer. Accordingly, serum albumin level could be used in clinical trials to better define the baseline risk in cancer patients. A critical gap for demonstrating causality, however, is the absence of clinical trials demonstrating that raising albumin levels by means of intravenous infusion or by hyperalimentation decreases the excess risk of mortality in cancer.

Dose escalation study of an anti-thrombocytopenic agent in patients with chemotherapy induced thrombocytopenia.

BACKGROUND: Preclinical studies demonstrated that small chain RNA fragments accelerate the recovery of platelets numbers in animals exposed to high doses of chemotherapeutic drugs. There is anecdotal data supporting the same application in humans. The Phase I clinical trial described here was designed to investigate the relationship between the administration of small chain RNA fragments and the recovery in platelets following Chemotherapy-Induced Thrombocytopenia (CIT). METHODS: Cancer patients with solid tumors that experienced post chemotherapy thrombocytopenia with a nadir of < = 80,000 platelets/ml were eligible for this clinical trial. There were no exclusions based on ECOG status, tumor type, tumor burden or chemotherapeutic agents. Patients received a unique preparation of RNA derived from either E. coli or yeast. Ten patients per group received 20, 40, or 60 mg as a starting dose. Subjects self-administered RNA fragments sublingually on an every other day schedule while undergoing chemotherapy. The dose was escalated in 20 mg increments to a maximum dose of 80 mg if the nadir was < 80,000 platelets/ml at the start of the next cycle. Subjects were treated for three cycles of chemotherapy with the maximum effective dose of RNA fragments. Subjects continued on planned chemotherapy as indicated by tumor burden without RNA fragment support after the third cycle. Subjects kept a diary indicating RNA fragment and magnesium administration, and any experienced side effects. RESULTS: Patients receiving E. coli RNA fragments demonstrated a more rapid recovery in platelet count and higher nadir platelet count. None of the patients receiving the E. coli RNA fragments required a chemotherapy dose reduction due to thrombocytopenia. The optimal dose for minimizing CIT was 80 mg. Conversely, subjects receiving yeast RNA fragments with dose escalation to 80 mg required a chemotherapy dose reduction per American Society of Clinical Oncology guidelines for grade 3 and 4 thrombocytopenia. CONCLUSIONS: Patients receiving myelosuppressive chemotherapy experienced an improvement in the platelet nadir and shorter recovery time when receiving concurrent E coli RNA fragments, when compared to patients who received yeast RNA fragments. These data indicate that 60 and 80 mg doses of E. coli RNA accelerated platelet recovery. Further clinical investigations are planned to quantify the clinical benefits of the E. coli RNA at the 80 mg dose in patients with chemotherapy induced thrombocytopenia. TRIAL REGISTRATION: Clinical Trials.gov Identifier: NCT01163110.

Impact of improved nutritional status on survival in ovarian cancer.

PURPOSE: Malnutrition is a common occurrence in ovarian cancer and is a major cause of morbidity and mortality. We evaluated the impact of improvement in nutritional status on ovarian cancer survival. METHODS: A retrospective chart review was performed on a case series of 98 ovarian cancer patients. Subjective global assessment (SGA) was used to evaluate nutritional status. Patients were classified as well-nourished (SGA A) or moderately-severely malnourished (SGA B/C). Patients were classified into four groups: (1) well-nourished at baseline and 3 months, (2) malnourished at baseline, well-nourished at 3 months, (3) malnourished at baseline and 3 months, (4) well-nourished at baseline, malnourished at 3 months. RESULTS: Of 98 patients, 20 were newly diagnosed while 78 had received prior treatment. The median age at presentation was 55.3 years. At baseline, the median survival for SGA A (N=46) was 20.3 months while for SGA B/C (N=52) was 9.8 months (p=0.03). At 3 months, the median survival for SGA A (N=63) was 19.9 months while for SGA B/C (N=35) was 3.7 months (p<0.001). Patients with an improved nutritional status at 3 months had a significantly better survival than those with deteriorated nutritional status independent of age, stage at diagnosis, prior treatment history, and tumor response as determined by CA125. CONCLUSIONS: Improvement in nutritional status is associated with better survival. Consequently, our findings lend support to the importance of aggressive nutritional intervention in improving patient outcomes in oncology.

Actigraphic assessment of daily sleep-activity pattern abnormalities reflects self-assessed depression and anxiety in outpatients with advanced non-small cell lung cancer.

OBJECTIVES: We measured subjectively evaluated depression and anxiety, and objectively measured daily sleep-activity patterns in inpatients and outpatients with advanced non-small cell lung cancer (NSCLC) and determined whether cancer-associated depression and anxiety are accompanied by characteristic circadian rhythm abnormalities. METHODS: Equal numbers of inpatients (n=42) and outpatients (n=42) with advanced NSCLC were studied. Baseline depression and anxiety, assessed by the Hospital Anxiety and Depression Scale (HADS), and actigraphy were recorded before chemotherapy initiation. The effects of the presence and severity of chronic obstructive pulmonary disease (COPD) on depression, anxiety, and actigraphy were assessed only among the 42 outpatients. RESULTS: Anxiety occurred in 40% and depression in 25% of these lung cancer patients, equally among inpatients and outpatients. All patients suffer extremely disturbed daily sleep-activity cycles but each patient also maintains some degree of circadian organization. Outpatients maintain more robust daily activity patterns and longer, more consolidated nighttime sleep compared with inpatients. The more disrupted the daily sleep-activity rhythm, the worse the depression and/or anxiety scores for outpatients. These relationships are obscured among inpatients. COPD has no independent measurable effects on the daily organization of sleep-activity, depression, or anxiety. CONCLUSIONS: Lung cancer patients whose diurnal activity is disturbed by prolonged and frequent sedentary episodes and whose sleep is disturbed by frequent and prolonged waking are most anxious and depressed. These findings and relationships are masked by hospitalization. Since diurnal exercise improves both sleep and mood, it is reasonable to test whether enhancing daytime activity and nighttime sleep can diminish cancer-associated depression.

Distribution and determinants of patient satisfaction in oncology: A review of the literature.

Cancer is one of the leading causes of morbidity and mortality in the United States. It places considerable mental, physical, and emotional stress on patients and requires them to make major adjustments in many key areas of their lives. As a consequence, the demands on health care providers to satisfy the complex care needs of cancer patients increase manifold. Of late, patient satisfaction has been recognized as one of the key indicators of health care quality and is now being used by health care institutions for monitoring health care improvement programs, gaining accreditation, and marketing strategies. The patient satisfaction information is also being used to compare and benchmark hospitals, identify best-performance institutions, and discover areas in need of improvement. However, the existing literature on patient satisfaction with the quality of cancer care they receive is inconsistent and heterogeneous because of differences in study designs, questionnaires, study populations, and sample sizes. The aim of this review was therefore to systematically evaluate the available information on the distribution and determinants of patient satisfaction in oncology.

Distribution and determinants of patient satisfaction in oncology with a focus on health related quality of life.

BACKGROUND: Cancer patients usually undergo extensive and debilitating treatments, which make quality of life (QoL) and patient satisfaction important health care assessment measures. However, very few studies have evaluated the relationship between QoL and patient satisfaction in oncology. We investigated the clinical, demographic and QoL factors associated with patient satisfaction in a large heterogeneous sample of cancer patients. METHODS: A cohort of 538 cancer patients treated at Cancer Treatment Centers of America (CTCA) was assessed. A patient satisfaction questionnaire developed in-house by CTCA was used. It covered the following dimensions of patient satisfaction: hospital operations and services, physicians and staff, and patient endorsements for themselves and others. QoL was assessed using the European Organization for the Research and Treatment of Cancer Quality of Life Questionnaire (QLQ-C30). The clinical, demographic and QoL factors were evaluated for predictive significance using univariate and multivariate logistic regression. RESULTS: The mean age of our patient population was 54.1 years (SD = 10.5, range 17-86), with a slight preponderance of females (57.2%). Breast cancer (n = 124) and lung cancer (n = 101) were the most frequent cancer types. 481 (89.4%) patients were "very satisfied" with their overall experience. Age and several QoL function and symptom scales were predictive of overall patient satisfaction upon univariate analysis. In the multivariate modeling, only those with a score above the median on the fatigue measure (i.e. worse fatigue) had reduced odds of 0.28 of being very satisfied (p = 0.03). CONCLUSION: Patient fatigue, as reported by the QoL fatigue scale, was an independent significant predictor of overall patient satisfaction. This finding argues for special attention and programs for cancer patients who report higher levels of fatigue given that fatigue is the most frequently reported symptom in cancer patients.

Role of CA125 in predicting ovarian cancer survival - a review of the epidemiological literature.

CA125 is the gold standard tumor marker in ovarian cancer. Serum level of CA125 is used to monitor response to chemotherapy, relapse, and disease progression in ovarian cancer patients. Thus, it is reasonable to investigate whether CA125 may have utility as a prognostic indicator as well in ovarian cancer. A large number of epidemiological studies have been carried out to this effect. This review summarizes all available epidemiological literature on the association between CA125 levels and survival in ovarian cancer. To place these studies in context, we provide some background information on CA125 and its role in ovarian cancer.
