Chromogranin A (CgA), a neuroendocrine secretory protein, and its fragments are present in variable amounts in the blood of normal subjects and cancer patients. We investigated whether circulating CgA has a regulatory function in tumor biology and progression. Systemic administration of full-length CgA, but not of fragments lacking the C-terminal region, could reduce tumor growth in murine models of fibrosarcoma, mammary adenocarcinoma, Lewis lung carcinoma, and primary and metastatic melanoma, with U-shaped dose-response curves...

Numerous clinical therapeutic agents have been identified as DNA damaging. The present study revealed that isoproterenol (Iso) resulted in DNA damage in vascular smooth muscle cells (VSMCs) and increased the levels of intracellular oxygen free radicals. Administration of chlorogenic acid (CGA) inhibited this effect. Pretreatment with CGA abrogated the increase in protein expression levels of γ‑H2A histone family member X, phosphorylated ataxia telangiectasia mutated, phosphorylated Rad3‑related protein, breast cancer 1 and C‑terminal Src homologous kinase induced by Iso...

The demographics of squamous cell carcinoma of the head and neck (SCCHN) is marked by a growing number of patients aged 65 and over, which is in line with global projections for other cancer types. In developed countries, more than half of new SCCHN cases are diagnosed in older people, and in 15 years from now, the proportion is expected to rise by more than 10%. Still, a high-level evidence-based consensus to guide the clinical decision process is strikingly lacking. The available data from retrospective studies and subset analyses of prospective trials suffer from a considerable underrepresentation of senior participants...

BACKGROUND: Lung cancer is one of the most lethal cancers. It is mainly classified into 2 groups: non-small cell lung cancer (NSCLC) and small cell lung cancer (SCLC). Extrapulmonary small cell carcinomas (EPSCC) are very rare. The Ras oncogene controls most of the cellular functions in the cell. Overall, 21.6% of human cancers contain a Kirsten Ras (KRAS) mutation. SCLC and EPSCC have several similar features but their clinical course is different. AIMS: We investigated the KRAS mutation status in SCLC and EPSCC...

Chlorogenic acid (CGA) is one of the polyphenols identified in the human diet. Previous studies have shown that CGA plays a protective role against liver diseases. The colon plays a pivotal role in CGA metabolism. However, little is known about the direct effects and the underlying molecular mechanisms of CGA in colon cancer. Here, we investigate these mechanisms of CGA activity in human colon cancer cells. The effects of CGA on the viability of two human colon cancer cell lines, HCT116 and HT29, were determined using the MTT assay...

The Comprehensive Geriatric Assessment (CGA) represents the future of the geriatric oncology to reduce toxicities and treatment-related hospitalization in the elderly. Most patients receiving docetaxel for metastatic castration-resistant prostate cancer are in their seventies or older. We explored the efficacy of the CGA in predicting chemotherapy feasibility and response to docetaxel in a cohort of 24 patients aged at least 70. This was an observational, prospective study involving 24 patients who were 70 years of age or older and about to start chemotherapy with docetaxel for metastatic castration-resistant prostate cancer; we performed a CGA including five domains and divided our patients into 'healthy' and 'frail'; the relations between general condition and (i) early chemotherapy discontinuation and (ii) response to docetaxel were explored...

Age-specific analyses of mortality rates in Japan show that cancer was the leading cause of death for the age group 40-89 years in the year 2013. Although the crude mortality rate from cancer has recently increased, the age-adjusted cancer mortality rate has shown a decreasing trend. This suggests that the increases in the crude mortality rate may have been caused by the aging of the population. Cancer patients who are old present many comorbidities and newly diagnosed geriatric problems. Several tools provide determinants of survival in cancer patients who are old (including the comprehensive geriatric assessment [CGA]) in order to improve the quality of cancer care in this population...

BACKGROUND: Frailty has been suggested as a construct for oncologists to consider in treating older cancer patients. Therefore, the authors assessed the potential of creating a deficit-accumulation frailty index (DAFI) from a largely self-administered comprehensive geriatric assessment (CGA). METHODS: Five hundred patients aged ≥65 years underwent a CGA before receiving chemotherapy. A DAFI was constructed, resulting in a 51-item scale, and cutoff values were examined for patients in the robust/nonfrail (cutoff value, 0...

BACKGROUND: Older patients undergoing surgery tend to have a higher frequency of delirium. Delirium is strongly associated with poor surgical outcomes. This study evaluated the association between pre-operative medication use and post-operative delirium (POD) in surgical oncology patients receiving comprehensive geriatric assessment (CGA). METHODS: A total of 475 patients who were scheduled for cancer surgery and received CGA from January 2014 to June 2015 were included...

INTRODUCTION: Frailty refers to a decreased physiologic reserve in geriatric patients and its importance in terms of treatment planning and outcome prediction has been emphasized in oncologic practices for older patients with cancer. We investigated the clinical implications of a head and neck cancer (HNC)-specific frailty index suggested by prospective clinical and functional evaluations of HNC patients. MATERIALS AND METHODS: We analyzed data on 165 elderly patients with HNC who were prospectively enrolled in our hospital from 2010 to 2013...

People over the age of 65 are often excluded from participation in oncological clinical trials. However, more than half of patients diagnosed with non-small-cell lung cancer are older than 65 years. Any therapeutic strategy must be discussed in multidisciplinary meetings after adapted geriatric assessment. Patients who benefit from the comprehensive geriatric assessment (CGA) of Balducci and Extermann are those whose G8 screening tool score is less than or equal to 14. Age itself does not contraindicate a curative therapeutic approach...

OBJECTIVE: Assess the utility of the G8 screening tool and CGA for older adults with head and neck cancer. METHODS: Patients 65years or older with a primary malignancy of the head and neck region were presented at the multidisciplinary team (MDT) meeting. The Geriatric 8 (G8) questionnaire was administered prior. Clinicians, blinded to the G8 result, made a recommendation on appropriate treatment, including potential referral for CGA. Patients considered vulnerable (G8 score≤14) were also to be referred for CGA...

BACKGROUND: The number of geriatric patients with esophageal cancer is increasing in step with the aging of the population. Geriatric patients have a higher risk of postoperative complications, including delirium that can cause a fall or impact survival. Therefore, it is very important that we evaluate risks of postoperative complications before surgery. The aim of this study was to predict postoperative delirium in elderly patients. METHODS: We retrospectively reviewed the medical records of 91 patients aged 75 years and over who underwent esophagectomy between January 2006 and December 2014...

Lung cancer is a disease that afflicts the elderly. It is a leading cause of cancer mortality worldwide. Treatment of lung cancer which was predominantly combination chemotherapy was initially thought to be too toxic for older patients with cancer due to their frail state. However a number of recent studies have shown that this is not necessarily true and many elderly can actually tolerate combination chemotherapy and derive just as much benefit from it as younger patients with lung cancer do. More recently it has been found that a significant proportion of lung cancer patients have tumors that harbor mutations that are targetable by molecularly targeted therapy (MTT)...

OBJECTIVE: Pancreatic neuroendocrine tumours (PNETs) are the major source of disease-specific mortality in multiple endocrine neoplasia type 1 (MEN1) patients. Chromogranin A (CgA), pancreatic polypeptide (PP), glucagon and gastrin have some diagnostic value in sporadic PNETs, but there is very little evidence for their efficacy in diagnosing PNETs in MEN1 patients. DESIGN: We performed a retrospective chart review of the existing MEN1 database in our institution...

PURPOSE: Elderly cancer patients are at increased risk for malnutrition. We aim to identify comprehensive geriatric assessment (CGA) based clinical factors associated with increased nutritional risk and develop a clinical scoring system to identify nutritional risk in elderly cancer patients. PATIENTS AND METHODS: CGA data was collected from 249 Asian patients aged 70 years or older. Nutritional risk was assessed based on the Nutrition Screening Initiative (NSI) checklist...

OBJECTIVES: The comprehensive geriatric assessment (CGA) can detect geriatric problems and potentially improve survival, physical, and cognitive state of patients, as well as increase an older person's chances of staying at home longer. In older people, the number and severity of comorbidity increase with age and are an important determinant of survival. The aim of the study was to assess to which extent CGA and comorbidities could be seen as determinants of survival. MATERIALS AND METHODS: This study analyzed data from two hospitals that included geriatric assessments of patients aged 70 years and more with cancer linked to mortality...

Chromogranin A (CgA), present in the chromaffin granules of neuroendocrine cells, is a useful biomarker for the diagnosis of patients with gastroenteropancreatic neuroendocrine tumors (GEP-NETs). This study was conducted to investigate the potential role of circulating CgA in monitoring clinical response in Chinese patients with advanced GEP-NETs. Eighty patients with advanced GEP-NETs treated in Peking University Cancer Hospital from September 2011 to May 2014 and 65 healthy individuals were included in this study...

Oncology services do not routinely assess broader needs of older people with cancer. This study evaluates a comprehensive geriatric assessment and comorbidity screening questionnaire (CGA-GOLD) covering evidence-based domains and quality of life (EORTC-QLQ-C30). Patients aged 65+ attending oncology services were recruited into (1) Observational cohort (completed CGA-GOLD, received standard oncology care), (2) Intervention cohort (responses categorised 'low-risk', 'high-risk', 'possible need' by geriatricians)...

OBJECTIVES: Frailty is a geriatric syndrome characterized by decreased physiological reserves and an age-related vulnerability to stressors with higher risk of adverse health outcomes. Comprehensive geriatric assessment (CGA) might detect frailty but is time-consuming, implying the need for initial frailty screening. Most frailty screening tools do not include functional measures. Hand grip strength (HGS) is a reliable surrogate for overall muscle strength and predicts functional decline, morbidity and mortality...
