1.Biomarkers for Evaluating the Inflammation Status in Patients with Cancer
Journal of Gastric Cancer 2019;19(3):254-277
Inflammation can be a causative factor for carcinogenesis or can result from a consequence of cancer progression. Moreover, cancer therapeutic interventions can also induce an inflammatory response. Various inflammatory parameters are used to assess the inflammatory status during cancer treatment. It is important to select the most optimal biomarker among these parameters. Additionally, suitable biomarkers must be examined if there are no known parameters. We briefly reviewed the published literature for the use of inflammatory parameters in the treatment of patients with cancer. Most studies on inflammation evaluated the correlation between host characteristics, effect of interventions, and clinical outcomes. Additionally, the levels of C-reactive protein, albumin, lymphocytes, and platelets were the most commonly used laboratory parameters, either independently or in combination with other laboratory parameters and clinical characteristics. Furthermore, the immune parameters are classically examined using flow cytometry, immunohistochemical staining, and enzyme-linked immunosorbent assay techniques. However, gene expression profiling can aid in assessing the overall peri-interventional immune status. The checklists of guidelines, such as STAndards for Reporting of Diagnostic accuracy and REporting recommendations for tumor MARKer prognostic studies should be considered when designing studies to investigate the inflammatory parameters. Finally, the data should be interpreted after adjusting for clinically important variables, such as age and cancer stage.

2.Advantages of Splenic Hilar Lymph Node Dissection in Proximal Gastric Cancer Surgery
Journal of Gastric Cancer 2020;20(1):19-28
Gastrectomy with lymph node dissection remains the gold standard for curative treatment of gastric cancer. Dissection of splenic hilar lymph nodes has been included as a part of D2 lymph node dissection for proximal gastric cancer. Previously, pancreatico-splenectomy has been performed for dissecting splenic hilar lymph nodes, followed by pancreas-preserving splenectomy and spleen-preserving lymphadenectomy. However, the necessity of routine splenectomy or splenic hilar lymph node dissection has been under debate due to the increased morbidity caused by splenectomy and the poor prognostic feature of splenic hilar lymph node metastasis. In contrast, the relatively high incidence of splenic hilar lymph node metastasis, survival advantage, and therapeutic value of splenic hilar lymph node dissection in some patient subgroups, as well as the effective use of novel technologies, still supports the necessity and applicability of splenic hilar lymph node dissection. In this review, we aimed to evaluate the need for splenic hilar lymph node dissection and suggest the subgroup of patients with favorable outcomes.

Secondary osteoporosis is a feature of rheumatoid arthritis (RA). In recent years, several attempts have been made to develop specific markers for monitoring connective tissue metabolism in arthritic diseases. Our purpose, in this study was to assess pyridinium crosslinks (PYD and DPYD) excretion in relation to the activity of RA (changes related to sulphasalazine treatment). Fourty premenopausal female patients with active RA (mean age; 36.0 7.2 years), 20 postmenopausal women with active RA (mean age; 60.0 6.8 years), 23 postmenopausal women with OA (mean age; 56.1 6.6 years) and 17 premenopausal healthy subjects (mean age; 28.3 4.28 years) were enrolled in our study. All of the 40 premenopausal female patients with active RA were given sulphasalazine. The mean follow up period for these patients was 10.3 1.1 months. In all of these patients, urine samples were collected both in the active and in the inactive periods. Urine PYD and DPYD levels were measured by ELISA. Urine PYD levels were significantly higher in the active period (14.01 3.16 nmol/mmol cr) than in the inactive (8.25 4.23 nmol/mmol cr) period in patients with premenopausal RA (p 0.05). Urine PYD levels were significantly high in postmenopausal active RA patients (19.06 3.26 nmol/mmol cr) compared to premenopausal active and ind inactive, postmenopausal inactive RA patients, osteoarthritis and healthy controls. Urine DPYD excretion was similar in patients with premenopausal RA in the active (7.46 2.13 nmol/mmol cr) and inactive periods (5.08 0.87 nmol/mmol cr) (p 0.05). In active premenopausal RA patients, a correlation was found between PYD excretion and RAI, ESR, CRP and functional capacity (r=0.5729 p 0.01, r=0.5953 p 0.01, r=0.6125 p 0.01 and r=0.6232, p 0.01 respectively). But in the inactive period, no such correlation was was evident. In disease activity parameters did not correlate with DPYD excretion in either the active or the inactive period. As a result, urine PYD excretion was significantly high in patients with active RA. During sulphasalazine treatment, urine PYD levels decreased. This is attributed to improvement in bone destruction.

Purpose:
This study aimed to investigate the relationship between clinical and laboratory parameters and complication status to predict which patients can be safely discharged from the hospital on the third postoperative day (POD).
Materials and Methods:
Data from a prospectively maintained database of 2,110 consecutive patients with gastric adenocarcinoma who underwent curative surgery were reviewed. The third POD vital signs, laboratory data, and details of the course after surgery were collected.Patients with grade II or higher complications after the third POD were considered unsuitable for early discharge. The performance metrics were calculated for all algorithm parameters. The proposed algorithm was tested using a validation dataset of consecutive patients from the same center.
Results:
Of 1,438 patients in the study cohort, 142 (9.9%) were considered unsuitable for early discharge. C-reactive protein level, body temperature, pulse rate, and neutrophil count had good performance metrics and were determined to be independent prognostic factors.An algorithm consisting of these 4 parameters had a negative predictive value (NPV) of 95.9% (95% confidence interval [CI], 94.2–97.3), sensitivity of 80.3% (95% CI, 72.8–86.5), and specificity of 51.1% (95% CI, 48.3–53.8). Only 28 (1.9%) patients in the study cohort were classified as false negatives. In the validation dataset, the NPV was 93.7%, sensitivity was 66%, and 3.3% (17/512) of patients were classified as false negatives.
Conclusions
Simple clinical and laboratory parameters obtained on the third POD can be used when making decisions regarding the safe early discharge of patients who underwent gastrectomy.
