Abstract
Brain metastasis is a common site of distant metastasis of non-small-cell lung cancer (NSCLC) that greatly reduces the prognosis of patients. In this study, we explored the correlation between different clinical factors and secondary brain metastases in NSCLC in an attempt to identify NSCLC patient populations at high risk of metastasis to the central nervous system.We collected data for 350 NSCLC patients from the medical record system of the First Affiliated Hospital of Nanchang University from June 2015 to June 2019, and these patients had pathologically verified diagnoses. The correlations between age at the time of diagnosis, sex, histological type, calcium concentration, hemoglobin (HB), fibrinogen (Fbg), activated partial thromboplastin time (APTT), alkaline phosphatase (ALP), carcinoembryonic antigen (CEA), CA125, and CA199 levels and brain metastasis were analyzed. Multivariate logistic regression analysis was used to identify risk factors for NSCLC brain metastasis. A receiver operating characteristic (ROC) curve was used to calculate the cutoff, sensitivity, and specificity of the independent related factors.Of the 350 patients, 57 were diagnosed with brain metastases. Univariate and multivariate logistic regression analysis indicated that lesion diameter, calcium concentration, and CEA level were independent risk factors correlated with brain metastasis (P < .05). There were no significant differences in age, sex, type of histopathology, presence or absence of mediastinal lymph node metastasis, HB, Fbg, APTT, ALP, cancer antigen 125 (CA-125), or cancer antigen 199 (CA-199) levels between patients with brain metastases and patients without brain metastases (P > .05, respectively). ROC curves demonstrated that these factors had comparable accuracy in predicting brain metastasis (area under the curve [AUCs] were 0.620, 0.661, and 0.729, respectively). The cutoff values for lesion diameter, calcium, and CEA were 5.050 cm, 2.295 mmol/L, and 11.160 ng/mL, respectively. The sensitivities for prediction brain metastasis were 59.6%, 64.9%, and 73.3%, with specificities of 63.1%, 59.2%, and 70.3%, respectively.According to our study, lesion diameter, calcium concentration, and CEA level are independent risk factors for brain metastases in NSCLC patients. Thus, we can strengthen the regular follow-up of NSCLC patients with tumor diameter > 5.050 cm, calcium > 2.295 mmol/L, CEA > 11.160 ng/mL, and use these factors as a reference for preventive treatments.

Abstract
WHAT IS KNOWN AND OBJECTIVE Nephrotoxicity is a frequently occurring side effect of cisplatin, which may be reduced by applying ample hydration. The aim of this study was to determine whether there is a difference in decline in renal function due to cisplatin between a short hydration (SH) and long hydration scheme (LH). METHODS A retrospective, observational, cohort study was conducted in two hospitals. Patients in one hospital received an SH scheme (SH group), whereas patients in the other hospital received an LH scheme (LH group). Other aspects of treatment and hydration were comparable between both patient groups. Consecutive patients (≥18 years) treated for non-small-cell lung cancer with cisplatin-pemetrexed with ≥1 cisplatin dose were included. Patients were excluded when serum creatinine at baseline was <40 μmol/L. Primary outcome was the difference in estimated glomerular filtration rate (eGFR) between baseline and after the last cisplatin cycle for the SH and LH patients, regardless of the number of administered cisplatin courses. RESULTS Fifty patients were included in the SH and LH group. There were no significant differences in baseline characteristics between the two groups. None of the patients had renal failure at baseline. After two cisplatin cycles, the median differences between the baseline eGFR and the eGFR after the last cisplatin dose were 1 (-6 to 5) and -9 (-22 to -2) mL/min/1.73 m2 (interquartile range) for the SH and LH group, respectively (P = .000). Less patients completed the four cycles in the LH group (16%) compared to the SH group (64%), mainly because more LH patients were switched to another treatment and due to nephrotoxicity. However, the difference in eGFR remained statistically significant (P = .027). WHAT IS NEW AND CONCLUSION In this retrospective study, the SH scheme resulted in less decrease in renal function compared with the LH scheme, with a significant and clinically relevant difference. Additionally, more LH patients had to stop this effective treatment prematurely due to nephrotoxicity. Therefore, a short hydration scheme provides adequate and safe hydration, with a lower risk of nephrotoxic side effects and therefore better outcomes for patients and a reduction of healthcare costs.

Abstract
BACKGROUND Loss of skeletal muscle mass is the corner stone of cancer cachexia, but no effective therapies are yet identified. The optimal protein quantity and pattern to support muscle mass maintenance in cancer patients is unknown. The aim of the current exploratory study was to observe the pattern and quantity of dietary protein intake as well as the prevalence of muscle wasting in patients with inoperable non-small cell lung cancer (NSCLC) undergoing primary anti-neoplastic treatment. The secondary aim was to assess the potential contributory factors associated with maintenance of muscle mass. METHOD A longitudinal observational study was conducted in patients with NSCLC undergoing first line of anti-neoplastic treatment. Nutrient intake was assessed by repeated 24-h recalls and skeletal muscle by routine thoraco-abdominal CT scans at baseline and after three cycles of treatment. Descriptive analyses, paired samples t-test, binomial logistic and linear regression analyses were performed. RESULTS Out of 186 consecutively screened patients, 62 were included and 52 patients were available for analysis. Protein intake increased from baseline to follow up, but were lower in muscle wasters (1.0 g/kg/d) than in muscle maintainers (1.4 g/kg/d). The majority of the meals contributed less than 20 g of protein and less than 10% of the meals contributed at least 40 g of protein. Significant loss of skeletal muscle area was observed in 26 out of 52 patients. A higher protein intake (OR 18.7, p = 0.01), energy intake (OR 1.1, p = 0.04) and stable body weight (OR 1.2, p = 0.03) were associated with muscle maintenance in the univariate regression, whereas age, sex, cachexia, tumour stage, treatment adherence and response did not. In the multivariate regression, a trend was seen for protein intake (OR 35.2, p = 0.08) and body weight (OR 1.2, p = 0.06). CONCLUSION Muscle wasting occurred frequently and early during primary anti-neoplastic treatment. Protein intake seems important for maintaining skeletal muscle. Validated dietary methods in cancer patients must be identified and the optimal protein quantity and intake pattern to support muscle maintenance should be explored in future trials.

Abstract
This study investigated the anti-inflammatory effects of omega 3 fatty acids (O3FAs) for patients with advanced nonsmall cell lung cancer (ANSCLC).A total of 137 patients with ANSCLC were included in this study. Of those, 77 patients underwent O3FA and were assigned to a treatment group, while 60 patients did not receive it, and were assigned to a control group. C-reactive protein (CRP), and interleukin (IL)-6 levels, as well as the levels of tumor necrosis factor-alpha (TNFα) and prostaglandin E2 (PGE2) were checked. In addition, nutritional status and quality of life were also evaluated. All patients in the treatment group received a total of 6 weeks treatment.After 6 weeks treatment, patients in the treatment group exerted better outcomes in CRP and IL-6, although no significant differences were found in nutritional status, as well as the quality, compared with patients in the control group.The results of this retrospective study found that O3FA may change levels of CRP and IL-6, except the nutritional status and quality of life.

Abstract
BACKGROUND Previous population-based studies have demonstrated an association between metformin use and improved survival among diabetic patients with cancer. We sought to analyze the effects of diabetes and its treatment in terms of the survival of patients with lung cancer. METHODS Overall, 1106 patients with non-small cell lung cancer (94.3 % with stage IV disease) were included. The outcomes were compared between the patients with (n = 186) and without diabetes (n = 920). The characteristics associated with antidiabetic treatment and proper glycemic control (defined as a mean plasma glucose <130 mg/dL) were examined at diagnosis. The overall survivals (OSs) of the different patient populations were analyzed using Kaplan-Meier curves, and a multivariate Cox proportional hazard model was used to determine the influences of the patient and tumor characteristics on survival. RESULTS The OS for the entire population was 18.3 months (95 % CI 16.1-20.4). There was no difference in the OSs of the diabetic and non-diabetic patients (18.5 vs 16.4 months, p = 0.62). The diabetic patients taking metformin exhibited a superior OS than did those on other antidiabetic treatments (25.6 vs 13.2 months, p = 0.017). Those with proper glycemic control had a better OS than did those without proper glycemic control and the non-diabetics (40.5 vs 13.2 and 18.5 months, respectively, p < 0.001). Both the use of metformin (HR 0.53, p < 0.0001 and HR 0.57, p = 0.017, respectively) and proper glycemic control (HR 0.49, p < 0.0001 and HR 0.40, p = 0.002, respectively) were significant protective factors in all and only diabetic patients, respectively. CONCLUSIONS The diabetic patients with proper glycemic control exhibited a better OS than did those without proper glycemic control and even exhibited a better OS than did the patients without diabetes mellitus. Metformin use was independently associated with a better OS.

Abstract
BACKGROUND The tumor microenvironment plays a critical role in tumor growth and spreading. Tumor-associated macrophages (TAM) make up a large proportion of the tumor mass and are one of the main producers of CC-chemokine ligand 18 (CCL18), which is believed to carry out important functions in the immunological interactions that promote tumor progression. MATERIALS AND METHODS Cytokines/chemokines were measured in bronchoalveolar lavage (BAL) from the tumor site and serum before and after resection in patients with proven non-small cell lung cancer (NSCLC). RESULTS CCL18 concentrations in BAL positively correlated with the radiologically determined tumor volume (r=0.72, p=0.0003) in NSCLC. In addition, tumors with lymph-node metastasis exhibited significantly higher CCL18 concentrations in BAL (p=0.049) than those without. Serum CCL18 concentrations did not differ significantly before and after tumor resection. CONCLUSION The increased release of CCL18 with greater tumor size is most likely due to the accompanied growth of leukocyte infiltrate. With previous findings taken into account, this could be one factor contributing to tumor invasiveness and particularly lymphatic spread in patients with larger tumors.

Abstract
AIM: Providing epidemiological data and treatment of anemia in lung cancer patients undergoing first-line chemotherapy. METHODS Epidemiological, observational, retrospective and multicenter study carried out at 30 sites throughout Spain. RESULTS The prevalence of anemia (hemoglobin [Hb] level <12 g/dl) was 18.3% and the incidence 80.7%. Mean Hb levels were 13.4 g/dl (95% Cl: 13.2-13.6) and 11.5 g/dl (95% Cl: 11.3-11.7) at starting and at the end of chemotherapy, respectively. Of the 294 patients with anemia, 174 (59.2%) were treated. Erythropoiesis-stimulating agents were given to 90.2% patients, alone in 31.6% and combined iron in 39.7%, transfusion in 9.2% and iron and transfusion in 9.8%. CONCLUSION These results suggest an appropriate and rational use of erythropoiesis-stimulating agents in the treatment of chemotherapy-associated anemia in lung cancer patients. [corrected].
