Cigarette smoking disparities among sexual minority cancer survivors

AbstractObjectiveSexual minority (i.e., lesbian, gay, and bisexual) adults smoke cigarettes at higher rates than heterosexual adults. Smoking after receiving a cancer diagnosis is a major health concern, yet risk of continued smoking among sexual minority cancer survivors is as yet unknown. The current study examines current smoking among sexual minority vs. heterosexual adult cancer survivors.MethodData drawn from the 2010 Behavioral Risk Factor Surveillance System survey in five states (Alaska, California, Massachusetts, New Mexico, and Wisconsin) included items about sexual orientation, cancer diagnosis, and tobacco use. The analytic sample included 124 sexual minority and 248 propensity score matched heterosexual adult cancer survivors.ResultsBivariate analysis showed that sexual minority cancer survivors had twice the odds of current smoking as their heterosexual counterparts (OR=2.03, 95%CI:1.09–3.80). In exploratory analyses stratified by sex, sexual minority disparities in prevalence of smoking post-cancer showed a trend toward significance among females, not males.ConclusionThe current study offers preliminary evidence that sexual minority status is one variable among many that must be taken into account when assessing health behaviors post-cancer diagnosis. Future research should identify mechanisms leading from sexual minority status to increased rates of smoking and develop tailored smoking cessation interventions

Racial Differences in Information Needs During and After Cancer Treatment: a Nationwide, Longitudinal Survey by the University of Rochester Cancer Center National Cancer Institute Community Oncology Research Program

Before treatment, cancer patients need information about side effects and prognosis, while after treatment they need information to transition to survivorship. Research documenting these needs is limited, especially among racial and ethnic minorities. This study evaluated cancer patients\u27 needs according to race both before and after treatment. We compared white (n = 904) to black (n = 52) patients receiving treatment at 17 National Cancer Institute Community Oncology Research Program (NCORP) sites on their cancer-related concerns and need for information before and after cancer treatment. Two-sample t test and chi-squared analyses were used to assess group differences. Compared to white patients, black patients reported significantly higher concerns about diet (44.3 vs. 25.4 %,) and exercise (40.4 vs. 19.7 %,) during the course of treatment. Compared to whites, blacks also had significantly higher concern about treatment-related issues (white vs. black mean, 25.52 vs. 31.78), self-image issues (7.03 vs. 8.60), family-related issues (10.44 vs. 12.84), and financial concerns (6.42 vs. 8.90, all p \u3c 0.05). Blacks, compared to whites, also had significantly greater post-treatment information needs regarding follow-up tests (8.17 vs. 9.44), stress management (4.12 vs. 4.89), and handling stigma after cancer treatment (4.21 vs. 4.89) [all p \u3c 0.05]. Pre-treatment concerns and post-treatment information needs differed by race, with black patients reporting greater information needs and concerns. In clinical practice, tailored approaches may work particularly well in addressing the needs and concerns of black patients

Nutritional Status Predicts Fatty Acid Uptake from Fish and Soybean Oil Supplements for Treatment of Cancer-Related Fatigue: Results from a Phase II Nationwide Study

Cancer-related fatigue is a prevalent and debilitating condition that persists for years into survivorship. Studies evaluating both fish oil supplementation on fatigue and associations between fish oil consumption and fatigue have shown mixed effects; it is unknown what factors contribute to these differential effects. Herein, we investigate whether the nutritional status of cancer survivors was associated with serum omega-3 concentration or change in serum omega-3s throughout a fish oil supplementation study, and then if any of these factors were associated with fatigue. Breast cancer survivors 4–36 months post-treatment with moderate-severe fatigue were randomized to take 6 g fish oil, 6 g soybean oil, or 3 g of each daily for 6 weeks. Baseline nutritional status was calculated using the Controlling Nutritional Status tool (serum albumin, lymphocytes, cholesterol). At baseline and post-intervention, serum fatty acids were quantified and fatigue was assessed using the Multidimensional Fatigue Symptom Inventory. Participants (n = 85) were 61.2 ± 9.7 years old with a body mass index of 31.9 ± 6.7 kg/m2; 69% had a good nutritional score and 31% had light-moderate malnutrition. Those with good nutritional status had greater total serum omega-3s at baseline (p = 0.013) and a greater increase in serum omega-3s with supplementation (p = 0.003). Among those who were supplemented with fish oil, greater increases in serum omega-3s were associated with greater improvements in fatigue. In conclusion, good nutritional status may increase uptake of fatty acid supplements, increasing their ability to improve fatigue

The Effects of a Mediterranean Diet Intervention on Cancer-Related Fatigue for Patients Undergoing Chemotherapy: A Pilot Randomized Controlled Trial

Cancer-related fatigue is a common, burdensome symptom of cancer and a side-effect of chemotherapy. While a Mediterranean Diet (MedDiet) promotes energy metabolism and overall health, its effects on cancer-related fatigue remain unknown. In a randomized controlled trial, we evaluated a rigorous MedDiet intervention for feasibility and safety as well as preliminary effects on cancer-related fatigue and metabolism compared to usual care. Participants had stage I–III cancer and at least six weeks of chemotherapy scheduled. After baseline assessments, randomization occurred 2:1, MedDiet:usual care. Measures were collected at baseline, week 4, and week 8 including MedDiet adherence (score 0–14), dietary intake, and blood-based metabolic measures. Mitochondrial respiration from freshly isolated T cells was measured at baseline and four weeks. Participants (n = 33) were 51.0 ± 14.6 years old, 94% were female, and 91% were being treated for breast cancer. The study was feasible, with 100% completing the study and >70% increasing their MedDiet adherence at four and eight weeks compared to baseline. Overall, the MedDiet intervention vs. usual care had a small-moderate effect on change in fatigue at weeks 4 and 8 (ES = 0.31, 0.25, respectively). For those with a baseline MedDiet score <5 (n = 21), the MedDiet intervention had a moderate-large effect of 0.67 and 0.48 at weeks 4 and 8, respectively. The MedDiet did not affect blood-based lipids, though it had a beneficial effect on fructosamine (ES = −0.55). Fatigue was associated with mitochondrial dysfunction including lower basal respiration, maximal respiration, and spare capacity (p < 0.05 for FACIT-F fatigue subscale and BFI, usual fatigue). In conclusion, the MedDiet was feasible and attenuated cancer-related fatigue among patients undergoing chemotherapy, especially those with lower MedDiet scores at baseline

Buspirone for management of dyspnea in cancer patients receiving chemotherapy: a randomized placebo-controlled URCC CCOP study

PURPOSE: Cancer-related dyspnea is a common, distressing, and difficult-to-manage symptom in cancer patients, resulting in diminished quality of life and poor prognosis. Buspirone, a non-benzodiazepine anxiolytic which does not suppress respiration and has proven efficacy in the treatment of generalized anxiety disorder, has been suggested to relieve the sensation of dyspnea in patients with COPD. The main objective of our study was to evaluate whether buspirone alleviates dyspnea in cancer patients. METHODS: We report on a randomized, placebo-controlled trial of 432 patients (mean age 64, female 51%, lung cancer 62%) from 16 participating Community Clinical Oncology Program (CCOP) sites with grade 2 or higher dyspnea, as assessed by the Modified Medical Research Council Dyspnea Scale. Dyspnea was assessed by the Oxygen Cost Diagram (OCD; higher scores are better) and anxiety by the state subscale of the State-Trait Anxiety Inventory (STAI-S; lower scores are better) at baseline and after the 4-week intervention (post-intervention). RESULTS: Mean scores from baseline to post-intervention for buspirone were OCD 8.7 to 9.0 and STAI-S 40.5 to 40.1 and for placebo were OCD 8.4 to 9.3 and STAI-S 40.9 to 38.6 with raw improvements over time on both measures being greater in the placebo group. Analysis of covariance (ANCOVA) controlling for baseline scores showed no statistically significant difference between groups for OCD (P = 0.052) or STAI-S (P = 0.062). CONCLUSION: Buspirone did not result in significant improvement in dyspnea or anxiety in cancer patients. Thus, buspirone should not be recommended as a pharmacological option for dyspnea in cancer patients
