Psychological correlates of sleep quality in lung cancer patients under chemotherapy: A single-center cross-sectional study.

OBJECTIVES: Disturbed sleep is a common complaint of lung cancer patients undergoing active oncologic treatment. We aimed to clarify the extent to which psychological symptoms, coping strategies, and social support interfere with sleep quality and whether they mediate the relationship between sleep quality and fatigue or functional capacity in a sample of chemotherapy treated lung cancer patients. METHODS: Lung cancer patients attending an oncology unit for scheduled chemotherapy cycles completed questionnaires assessing their sleep quality, fatigue, depression, anxiety, stress, coping, social support, symptoms of pain, dyspnea, and cough, and sleep hygiene practices. Demographic and disease-related characteristics were obtained from patients' medical records and treating physicians rated their functional status. Multivariate regression and mediation analyses were applied to test the study's hypotheses. RESULTS: One hundred nineteen patients were enrolled, 58.2% of whom were identified as poor sleepers. After adjusting for age, gender, comorbidities, concomitant medications, cancer stage, prior and ongoing treatment, sleep hygiene, and symptoms, there was a statistically significant association between poor sleep quality and anxiety (odd`s ratio [OR] 1.17 [95% CI, 1.01-1.35]), stress (OR 1.14 [95% CI, 1.04-1.25]), and positive coping (OR 1.15 [95% CI, 1.02-1.31]). Poor sleep quality was an independent correlate of fatigue (B 1.56 [95% CI, 0.61-2.50]) and low performance status (OR 5.17 [95% CI, 1.60-16.72]); stress symptoms partially mediated the relationship between sleep quality and fatigue (P = .030). CONCLUSIONS: Higher psychological burden predict sleep disturbances and contribute to increased fatigue in lung cancer patients undergoing chemotherapy. Effective psychoeducational interventions may benefit these populations.

Nonpharmacologic Interventions for Improving Sleep Disturbances in Patients With Lung Cancer: A Systematic Review and Meta-analysis.

CONTEXT: Lung cancer patients experience higher levels of sleep disturbances compared to other cancer patients, and this leads to greater distress, poorer function, and lower quality of life. Nonpharmacologic interventions have demonstrated improvements in the context of breast cancer, but their efficacy in the lung cancer population is unclear. OBJECTIVES: The aim of this review was to determine the effects of any nonpharmacologic intervention on sleep quality of lung cancer patients. METHODS: Intervention studies of any design that reported primary or secondary outcomes on sleep quality were included. Databases searched were Cochrane Central Register of Controlled Trials, MEDLINE, EMBASE, CINAHL, and PsycINFO. Risk of bias was assessed regarding randomization, allocation concealment, blinding, incomplete outcome data, selective reporting, and other biases. RESULTS: Twenty-two studies were identified with a total of 1272 participants. Pittsburgh Sleep Quality Index was the most common instrument used. Statistically significant results were observed for all intervention categories examined in the short-term follow-up period: exercise and rehabilitation programs (standardized mean difference [SMD]: -0.43, 95% CI: -0.68, -0.19, P = 0.0005); information, psychoeducation, and symptom screening interventions (SMD: -0.87, 95% CI: -1.21, -0.54, P < 0.00001); and mind-body interventions (SMD: -0.88, 95% CI: -1.59, -0.16, P = 0.02). However, effectiveness was lower and nonsignificant when evaluated over one month after completion. CONCLUSION: Limitations include the high heterogeneity of interventions and outcome measures, in addition to small sample sizes and high risk of bias within studies. Because they do not allow for a clear interpretation of the results, it is recommended that every patient should be assessed individually to guide a possible referral.

Bone metastases in patients with small cell lung carcinoma: rate of development, early versus late onset, modality of treatment, and their impact on survival. A single-institution retrospective cohort study.

The aim of the present study was to further explore the impact of bone metastases (BMs) and their therapeutic management on the overall prognosis of patients with small cell lung carcinoma (SCLC). We performed a retrospective analysis of medical records of 363 patients with histologically or cytologically confirmed SCLC, diagnosed and treated in the Oncology Unit of Sotiria Athens General Hospital, between January 2003 and December 2012. Demographic and clinicopathological features, including BMs, their time point of development (early onset/at diagnosis versus late onset/at a subsequent time point), treatment modality for BMs (radiotherapy, bisphosphonates or both) and the presence of skeletal-related events (SREs), were correlated with overall survival (OS). Survival analysis was performed using the Kaplan-Meier method, log-rank tests and Cox regression analysis. Overall, 130/363 patients (35.8 %) were diagnosed with either early-onset (97/363 cases, 26.7 %) or late-onset BMs (33/363 cases, 9.1 %). Patients with early-onset BMs had a reduced OS as compared to those with late-onset BMs [Hazard ratio (HR) 0.61; 95 % Confidence interval (CI) 0.41-0.91; p = 0.015) or those without BMs (HR 0.76; 95 % CI 0.6-0.96; p = 0.024). SREs and treatment modality of BMs had no impact on OS. Multiple Cox regression analysis showed that increased age, poor performance status (PS), presence of BMs and early onset BMs were independently associated with reduced OS. The results of our single-institution study suggest that the development of early-onset BMs may represent an independent predictor of a worse prognosis among patients with SCLC, in addition to well-established adverse prognostic factors such as poor PS.

Quality of life in patients with pancreatic cancer.

QOL is highly affected in individuals suffering from pancreatic cancer. One parameter that influences negatively QOL in these patients is cancer -cachexia syndrome. During the ASCO Annual Meeting 2014, one abstract focusing on cancer-cachexia syndrome (Abstract #15208) emphasized the fact that cachexia is under diagnosed even in patients with pancreatic cancer who constitute a high-risk group for presenting this syndrome. In addition the abstract raises concerns about the benefit of the use of dronabinol and megestrol acetate in treating the cachexia syndrome in this group of patients. Another important factor that determines QOL in pancreatic cancer patients is surgical procedures-pancreatectomies that these patients may undergo. A very interesting abstract presented also at the ASCO Annual Meeting 2014 (Abstract #15234) explores the benefit of using pasireotide perioperative in ameliorating QOL of patients who had surgical intervention.

Nutrition habits, physical activity, and lung cancer: an authoritative review.

Lung cancer is the leading cause of cancer death worldwide. Because of high incidence rates and low survival rates, it is important to study the risk factors that may help prevent the disease from developing. It has been well established that cigarette smoking is the most important risk factor for lung cancer. Nonetheless it is likely that there are other modifiable risk factors that would assist in the prevention of lung cancer. Research on factors such as nutrition and physical activity and their influence on lung cancer has been carried out for nearly 3 decades. A systematic review in the MEDLINE database of published studies was conducted, focusing on systematic reviews, meta-analyses, and large prospective studies. The association between physical activity and lung cancer has been conflicting. Among the researched studies, 10 showed an inverse association, whereas 11 reported no association. A meta-analysis that was conducted from 1996 to October 2003 showed that leisure physical activity (LPA) prevents lung cancer. Data from 11 cohort and case-control studies showed an inverse relationship between fruit and vegetable consumption and lung cancer. Evidence from case-control studies suggests a positive association between meat intake and risk of lung cancer, although several more recent studies have presented doubts about these findings. The possible association of physical activity, nutrition, and the risk of lung cancer development remains controversial. Further prospective studies should be conducted to determine the potential influence of these 2 risk factors.

Prolonged survival after splenectomy in Wiskott-Aldrich syndrome: a case report.

Wiskott-Aldrich syndrome is a rare X-linked immunodeficiency disorder that is characterized by a variable clinical phenotype. Matched donor bone marrow transplantation is currently the only curative therapeutic option. We present the case of a 24-year-old male who was diagnosed at the age of seven with Wiskott-Aldrich syndrome. He did not respond to intravenous gammaglobulin and he experienced recurrent pulmonary infections despite prophylactic antibiotics. The patient had no matched donor. At the age of nine, he was submitted to splenectomy and his platelet count was normalized. Fifteen years later, the patient remains asymptomatic with a normal platelet count. He is still receiving prophylactic antibiotics and no bleeding episodes or septic complications have been reported. This case demonstrates that splenectomy can represent a safe therapeutic option in selected WAS patients, provided that there is a tight follow-up program, patient education and adherence to guidelines regarding post-splenectomy prophylaxis.

The clinical significance of serum markers of bone turnover in NSCLC patients: surveillance, management and prognostic implications.

The purpose of this study was to investigate various serum markers of bone turnover in non-small cell lung cancer patients (NSCLC) in the presence or absence of bone metastasis. Our retrospective study included 79 newly diagnosed NSCLC patients. Group A included 51 patients with bone metastasis and group B included 28 patients that never developed bone metastasis. The measurement of bone formation markers, bone resorptive markers and osteoclastogenesis markers as well as routine biochemical analysis was determined. Patients with bone metastasis had an increase in receptor activator of nuclear factor kappaB ligand, osteopontin and osteoprotegerin. Patients who later developed bone metastasis had decreased osteocalcin and tartrate-resistant acid phosphatase isoform 5b levels (TRACP-5b). We also found an unusually low TRACP-5b/RANKL ratio for patients who have or later developed metastasis. In patients that never developed bone metastases, cross-linked carboxy-terminal telopeptide of type I collagen was increased. Positive correlations were found between osteopontin and TRACP-5b, and also between bone alkaline phosphatase with osteocalcin and TRACP-5b. In conclusion, serum markers of bone turnover may be able to determine the time-to-tumor progression, metastatic potential and overall survival of the NSCLC patient. In addition, they may contribute to a more accurate follow-up and tailored treatment options.

Safety and efficacy of zoledronic acid rapid infusion in lung cancer patients with bone metastases: a single institution experience.

Zoledronic acid (Zometa, Novartis, Basel, Switzerland) is a new generation of bisphosphonates (BPs) with demonstrated clinical benefit in breast and prostate cancer patients with bone metastases. The safety and efficacy of intravenous zoledronic acid in lung cancer patients was assessed. In 86 patients with newly diagnosed non-small cell lung cancer (NSCLC) or small cell lung cancer (SCLC) and bone metastases, 4 mg of zoledronic acid was administered with rapid 15-minute intravenous infusion every 3-4 weeks. A total of 414 infusions were administered over a 24-month period during which a statistically significant decrease in serum calcium levels (p = 0.03) was observed. Serum alkaline phosphatase (ALP) also decreased but not significantly. With regard to clinical efficacy, 55 of our patients stabilized or reduced their need for analgesic treatment. No significant side-effects, including fever, hemodynamic instability and renal dysfunction, were seen. We conclude that the rapid infusion of zoledronic acid is safe and convenient for lung cancer patients even after the 3rd and 6th months follow-up.

Rapid infusion of ibandronate in lung cancer patients with bone metastases.

BACKGROUND: The high prevalence of bone metastases in stage IV non-small cell lung cancer (NSCLC) patients contributes substantially to the burden of the disease by resulting in significant skeletal morbidity. Ibandronate is a new generation of bisphosphonates (BPs) with demonstrated clinical benefit in breast and prostate cancer patients with bone metastases. PATIENTS AND METHODS: In 32 patients with newly diagnosed NSCLC and bone metastases, 4 mg of ibandronate were administered, as a rapid 20-minute intravenous infusion every 3-4 weeks. RESULTS: A total of 189 infusions were administered over a 24-month period, during which a statistically significant decrease in calcium serum levels (p=0.03) was observed. The serum levels of alkaline phosphatase (ALP) were also decreased, but not significantly. With regard to clinical efficacy, 24 of our patients stabilized or reduced their need for analgesic treatment. The reduced time of infusion (20 min vs. 2 h) did not correlate with any side-effects, including vital sign deterioration and renal dysfunction. CONCLUSION: The rapid infusion of ibandronate in lung cancer patients with bone metastases is a safe and convenient procedure that may be administered in a day-clinic setting.

Metastatic cervical carcinoma to the thyroid gland: a case report and review of the literature.

Although metastases within the thyroid gland are rare, they are not as infrequent as generally believed. Asymptomatic breast, lung, and renal cell carcinomas may metastasize to the thyroid. When they become symptomatic, diagnosis relies upon fine needle aspiration cytology. We report the case of a squamous cell cervical cancer that presented metastatic lesions to the thyroid gland four years after the initial diagnosis. The procedures used to confirm the diagnosis, stage, and subsequently manage the patient are described. We present both a review of the necessary clinical investigation and the therapeutic options open to these patients. We conclude that patients who present swelling or palpable nodules in the thyroid side and have a history of a previous malignancy must be considered for metastatic disease.
