RESUMO
BACKGROUND/AIM: Matrix metalloproteinase 9 (MMP9) is highly expressed in gastric cancer but the role of MMP9 is unclear. This study aimed at revealing the association of MMP9 promoter rs3918242 genotypes with gastric cancer risk. MATERIALS AND METHODS: MMP9 rs3918242 genotypes of 121 patients with gastric cancer and 363 healthy individuals were examined by polymerase chain reaction-restriction fragment length polymorphism methodology using serum samples. RESULTS: MMP9 rs3918242 TT genotype carriers had an elevated gastric cancer risk compared to wild-type CC carriers (odds ratio=3.92, 95% confidence interval=1.28-11.99; p=0.0103). Patients with CT/TT genotypes were at higher risk of metastasis (p=0.0178) than those with CC. No correlation was found between MMP9 rs3918242 genotype and gastric cancer risk with smoking or alcohol behavior, nor Helicobacter pylori infection. No correlation was observed for MMP9 rs3918242 genotypic distributions with age, gender, or body mass index. CONCLUSION: Carrying a T allele for MMP9 rs3918242 may be predictive for higher gastric cancer risk, and as a predictor for higher risk of metastasis.

CONTEXT: The accurate prediction of survival is one of the key factors in the decision-making process for patients with advanced illnesses. OBJECTIVES: This study aimed to develop a short-term prognostic prediction method that included such objective factors as medical history, vital signs, and blood tests for use with patients with advanced cancer. METHODS: Medical records gathered at the admission of patients with advanced cancer to the hospice palliative care unit at a tertiary hospital in Taiwan were reviewed retrospectively. The records included demographics, history of cancer treatments, performance status, vital signs, and biological parameters, Multivariate logistic regression analyses and receiver operating characteristic curves were used for model development. RESULTS: The Objective Palliative Prognostic Score was determined by using six objective predictors identified by multivariate logistic regression analysis. The predictors include heart rate >120/min, white blood cells >11,000/mm(3), platelets <130,000/mm(3), serum creatinine level >1.3 mg/dL, serum potassium level >5 mg/dL, and no history of chemotherapy. The area under the receiver operating characteristic curve used to predict seven-day survival was 82.0% (95% confidence interval 75.2%-88.8%). If any three predictors of the six were reached, death within seven days was predicted with 68.8% sensitivity, 86.0% specificity, 55.9% positive predictive value, and 91.4% negative predictive value. CONCLUSION: The Objective Palliative Prognostic Score consists of six objective predictors for the estimation of seven-day survival among patients with advanced cancer and showed a relatively high accuracy, specificity, and negative predictive value. Objective signs, such as vital signs and blood test results, may help clinicians make decisions at the end of life.

BACKGROUND/PURPOSE: As the number of terminal cancer patients increases, several care models have been adopted to provide better care quality and reduce medical expenditure. This study compared inpatient medical expenditure and family satisfaction in a hospice ward (HW) and general ward (GW) for terminal cancer patients in Taiwan. METHODS: We enrolled terminal cancer patients who were admitted and died during the same admission period in a tertiary care hospital in Taiwan from January 2003 to December 2005. These patients were allocated into three groups: inpatient care in HW alone; inpatient care in GW alone; and inpatient care in mixed group (initially in GW, then transferred to HW). Inpatient medical expenditure and family satisfaction were compared between the three groups. RESULTS: A total of 1942 patients were recruited and allocated into HW (n = 292), GW (n = 1511) and mixed (n = 139) groups. The average medical expenditure per person or per inpatient day was lower in the HW than the GW or mixed group. Subjects who had ever been admitted to the intensive care unit or received cardiopulmonary resuscitation in the GW or mixed groups required more expenditure on medical care than that in the HW group. Daily medical expenditure in the HW group also was much lower than that in the GW and mixed groups, based on length of stay and cancer type. The family satisfaction score was significantly higher in the mixed and/or HW group than the GW group. CONCLUSION: For terminal cancer patients, hospice care can improve family satisfaction while reducing medical expenditure in Taiwan.
