BackgroundResearchers in recent studies have reported that the sonic hedgehog (Shh) signaling pathway plays a crucial role during tumorigenesis, angiogenesis and cellular differentiation. We investigated the clinical and pathological significances of the Shh pathway and of its lymphangiogenic components in non-small-cell lung cancer (NSCLC), namely, Shh, glioma-associated oncogene homolog zinc finger protein 1 (Gli1), lymphatic vessel endothelial hyaluronan receptor 1 (LYVE-1) and vascular endothelial growth factor D (VEGF-D).MethodsThe expression of Shh, Gli1, LYVE-1 and VEGF-D in primary NSCLC tissue from 40 patients was examined using immunohistochemical assays, and relationships between expression and clinicopathological data, such as age, gender, histology, tumor size, nodal stage, visceral pleural invasion, lymphatic thromboembolism, recurrence and overall survival were investigated.ResultsOf the 40 specimens examined, 25 (62.5%), 20 (50.0%), 11 (27.5%) and 20 (50.0%) were positive for Shh, Gli1, LYVE-1 or VEGF-D expression, respectively. The expression of Gli1 and LYVE-1 were significantly associated (P = 0.011), and Shh and LYVE-1 expression was related to visceral pleural invasion and lymphatic thromboembolism, respectively (P < 0.05). Shh expression levels compared on survival curves were statistically significant in univariate logrank analysis (P = 0.020). However, other clinicopathological factors did not reveal any statistical significance in univariate and multivariate analyses.ConclusionsTo our knowledge, this the first report of the relationship between components of the Shh signaling pathway and prognosis in NSCLC. The expression of Shh, Gli1 and LYVE-1 was found to be associated with clinicopathological factors and survival. Thus, the overexpression of the Shh signaling pathway could serve as a predictor of malignant behavior, including lymphangiogenesis, in NSCLC.
Background: Palliative care services and life-sustaining treatments are provided to dying patients with lung cancer in the United States. However, data on the utilization trends of palliative care services and life-sustaining treatments of dying patients with lung cancer are not available. Methods: This study was a retrospective analysis of the National Inpatient Sample data (2005-2014) and included patients with lung cancer, aged ≥ 18 years, who died in the hospitals. Claims data of palliative care services and life-sustaining treatments that contained systemic procedures, local procedures, or surgeries were extracted. Compound annual growth rates (CAGRs) using Rao-Scott correction for χ2 tests were used to determine the statistical significance of temporal utilization trends of palliative care services and life-sustaining treatments and their hospital costs. Multilevel multivariate regressions were performed to identify factors associated with hospital costs. Results: A total of 120 144 weighted patients with lung cancer died in the hospitals and 41.9% of them received palliative care services. The CAGRs of systemic procedures, local procedures, surgeries, palliative care services, and hospital cost were 3.42%, 3.48%, 6.08%, 18.5%, and 5.0% (all P < .001), respectively. Increased hospital cost was attributed to systemic procedures (50.6%), local procedures (74.4%), and surgeries (68.5%; all P < .001), respectively. Palliative care services were related to decreasing hospital costs by 28.6% ( P < .001). Conclusion: The temporal trends of palliative care services indicate that their utilization has increased gradually. Palliative care services were associated with reduced hospital costs. However, life-sustaining treatments were associated with increased hospital costs.
Aim: Pancreas cancer continues to carry a poor prognosis. Hospitalized patients with advanced chronic pancreatic illnesses increasingly receive palliative care due to its perceived clinical benefits. Meanwhile, a growing proportion of elderly patients are reportedly receiving life-sustaining procedures. Temporal trends in the utilization of life-sustaining procedures and palliative care consultation among dying patients with advanced chronic pancreatic illnesses in US hospitals were examined. Methods and Materials: A serial, cross-sectional analysis was carried out using the National Inpatient Sample Database. Decedents 18 years and older with a principal diagnosis of pancreas cancer or other advanced chronic pancreatic illnesses from 2005 through 2014. The compound annual growth rates (CAGRs) and Cochrane-Armitage correction of χ2 statistic were used. The receipt of life-sustaining systemic procedures, intra-abdominal local procedures and surgeries, and palliative care consultation were examined. Multilevel multivariate logistic regressions were performed to examine the association of various procedures with the utilization of palliative care consultation. Results: Among 77 394 183 hospitalizations, 29 515 patients were examined. The CAGRs of systemic procedures, intra-abdominal procedures, surgeries, and palliative care were −4.19% ( P = .008), 2.17%, −1.40%, and 14.03% ( P < .001), respectively. The receipt of systemic procedures (odds ratio [OR] = 2.40, 95% confidence interval [CI], 2.08-2.74), local intra-abdominal procedures (OR = 1.46, 95% CI, 1.27-1.70), and surgeries (OR = 2.51, 95% CI, 2.07-3.05) was associated with palliative care consultation ( Ps < .001). Conclusions: Among adults with pancreatic cancer or other advanced chronic pancreatic illnesses in the US hospitals from 2005 to 2014, the utilization of life-sustaining systemic procedures decreased while the prevalence of palliative care consultation increased.
Background: Non-intubated thoracoscopic surgery can be performed under sedation using adjuvant regional anesthesia, however, the benefits of non-intubated thoracoscopic surgery under sedation have not yet been completely verified. In this study, we compare the perioperative safety and pain complaints of sedation without intubation in thoracoscopic bullectomy with that of conventional general anesthesia with double-lumen intubation and mechanical ventilation. Methods: Forty-one patients with primary spontaneous pneumothorax who were scheduled for thoracoscopic bullectomy were enrolled in this study. Twenty-one patients were under sedation anesthesia (SA group) and 20 patients were under general anesthesia (GA group). In SA group, sedation was done with dexmedetomidine (a loading dose of 1 μg/kg for 10 min and then maintained in dosages of 0.3-1 μg/kg/h) and ketamine (2-4 mg/kg/h intraoperatively). Meanwhile, in GA group, induction with propofol and rocuronium, intubation with double lumen endotracheal tube and maintenance with 1.0-2.5% sevoflurane was done. In both groups, thoracoscopic bullectomy was performed in the same manner and all operations were conducted by single surgeon. Time for anesthesia [including emergence time and post-anesthesia care unit (PACU) recovery time] and operation, postoperative pain, sore throat, hoarseness, adverse events (nausea, vomiting, hypotension and bradycardia), dose of rescue analgesic drug used for 24 hours post-operatively and perioperative arterial blood gas analysis were recorded. Results: The times for anesthesia, operation and emergence were significantly shorter in SA than GA.Incidence of sore throat were significantly lower in SA. The difference of other adverse events in the two groups was not significant. Conclusions:Our study demonstrated that compared to double-lumen intubation with general anesthesia, non-intubation with sedation for bullectomy for primary spontaneous pneumothorax was safe and efficient to reduce perioperative time.
Primary pericardial malignant mesothelioma (PPM) is a very rare malignancy, with an incidence of less than 0.002% and represents less than 5% of all mesotheliomas. The cause of pericardial mesothelioma is uncertain that differ from pleural mesothelioma which is associated with asbestos exposure. This malignancy is terribly aggressive and has very poor prognosis with less than six months of overall survival. We present a case of a 71-year-old woman who was diagnosed with cardiac tamponade caused by PPM and received chemotherapy with pemetrexed and cisplatin for six months. During two years she was alive without disease progression. To better understand the clinical, pathologic features and treatment outcome of this entity, we reviewed 23 cases described in the English literature from 2009, together with our case, provided a total of 24 cases. Based on this review, we suggest that PPM must be considered in patients who have unexplained massive pericardial effusion and recommend chemotherapy with pemetrexed and cisplatin for the better outcome of PPM.
VATS-IFRR was safe and had several advantages. Thus, VATS-IFRR is a minimally invasive surgical option suitable for treating selective cases of TOS.
Study Design. Serial cross-sectional study utilizing the National Inpatient Sample (NIS) 2005 to 2014. Objective. The aim of this study was to examine the trends of opioid-use disorders among hospitalized patients with spinal conditions and treatment and to identify its contributing factors. Summary of Background Data. The opioid is widely used in chronic spinal conditions, and misuse of prescriptions is the main culprit of the opioid crisis. Cannabis, the most commonly utilized illicit drug, has recently been substituted for opioid despite increasing cannabis-use emergency room visits. There is limited information on opioid-use disorders, the association with cannabis, and other contributing factors. Methods. We analyzed the 2005 to 2014 NIS data that identified opioid-use disorders among hospitalized patients with cervical and lumbar spinal conditions and treatment using the International Classification of Disease, Ninth Revision-Clinical Modification codes for opioid abuse, dependence, poisoning, and cervical and lumbar spinal diseases and procedures. The compound annual growth rate (CAGR) was used to quantify trends of opioid-use disorders among hospitalized patients. Multilevel and multivariable regression analyses were performed to determine their contributing factors. Results. The number of hospitalizations with spinal conditions and treatment increased from 2005 to 2011, then decreased between 2011 and 2014 with an overall decrease in length of stay, resulting in the CAGR of −1.60% (P < .001). Almost 3% (2.93%, n = 557,423) of hospitalized patients with spinal conditions and treatment were diagnosed as opioid-use disorders and its CAGR was 6.47% (P < .0001). Opioid-use disorders were associated with cannabis-use disorders (odds ratio 1.714), substance use, mental health condition, younger age, white race, male sex, higher household income, and public insurance or uninsured. Conclusion. This study suggests that opioid-use disorders are increasing among hospitalized patients with spinal conditions and treatment and associated with several demographic, and socioeconomic factors, including cannabis-use disorders.
