OBJECTIVE: To investigate the value of the HCT-CI score in chemotherapy risk assessment and prognosis of elderly patients with acute myeloid leukemia (AML). METHODS: The clinical data of 116 AML patients older than 60 years in the department of Hematology, Henan Provincial People's Hospital from January 2000 to December 2010 were analyzed retrospectively. All patients received cytarabine-based regimens, including protocol DA, MA, IA, AA or CAG, followed by cytarabine-based postremission treatment. (1) Comorbidities were evaluated by using HCT-CI score, the early death rates and median survival time were compared among these different groups. (2) These prognostic factors were analyzed by univariate and multivariate analyses. RESULTS: (1) All 116 cases were followed-up. The patient cohort was divided into those with HCT-CI scores of 0, 1 or 2, or ≥ 3. Early death rates were 3.7%, 12.1% and 23.21% in above three groups, respectively (P < 0.01). Overall survival were 345, 225 and 113 days, respectively (P < 0.01). (2) HCT-CI score ≥ 3 (P < 0.01), antecedent MDS history (P = 0.035), high-risk karyotype (P = 0.018), white blood cells at diagnosis ≥ 100×10(9)/L (P = 0.041) were independent adverse prognostic factors with multivariate analysis. CONCLUSION: (1) The HCT-CI score can objectively assess elderly AML patients with comorbidities and predict chemotherapy risk in older patients receiving AML induction therapy. (2) Antecedent MDS history, high-risk karyotype, high white blood cell, and HCT-CI score ≥ 3 are independent adverse prognostic factors of elderly AML patients.

AIM: To characterize the histochemical type and pattern of intestinal metaplasia (IM) adjacent to gastric cardia adenocarcinoma (GCA) and distal gastric cancer (GC) in Linzhou, Henan Province, China. METHODS: Alcian-blue-periodic acid Schiff and high iron diamine-Alcian blue histochemical methods were performed on 142 cases of IM, including 49 cases of GCA and 93 cases of GC. All the patients were from Linzhou, Henan Province, China, the highest incidence area for both GCA and squamous cell carcinoma. Radio- or chemotherapy was not applied to these patients before surgery. RESULTS: The detection rate of IM in tissues adjacent to GCA tissues was 44.9%, which was significantly lower than that in GC tissues (80.64%, P<0.01). The rates of both incomplete small intestinal and colonic IM types identified by histochemistry in GCA tissues (31.82% and 63.64%, respectively) were significantly higher than those in GC (5.33% and 21.33%, respectively, P<0.01). CONCLUSION: IM in GCA and GC should be considered as a separate entity. Further research is needed to evaluate whether neoplastic progression of IM is related to its mucin profile in GCA.
