影响原发性肝癌肝移植治疗的预后因素分析

目的分析影响肝癌肝移植术后生存率和无瘤生存率的危险因素,探讨国内肝移植治疗肝癌的选择标准。方法对67例接受同种异位原位肝移植治疗的原发性肝癌病人的基本资料和肿瘤相关资料包括术前病情分级、血清AFP水平、术前辅助治疗以及肝癌大小、数目、pTNM分期、肿瘤恶性程度分级等因素进行单因素和多因素分析。结果术后1年、2年累积生存率为77%、67%,6个月和12个月无瘤生存率为66%和58%。单因素分析显示对肝癌肝移植术后累积生存率影响有统计学意义的因素为CHILD分级(MELD积分)和肝外大血管侵犯;多因素分析影响肝癌肝移植术后无瘤生存率有统计学义的因素是肿瘤大小、大血管侵犯和肿瘤分化程度。结论影响肝癌肝移植术后生存率的因素仍是术前患者肝功能状态。对存在大血管侵犯的肝癌患者需严格控制肝移植术适应证,而无血管侵犯的患者在选择肝移植治疗时肿瘤大小指标可较米兰标准适当放宽。     

Depressed host immunity in a case of metachronous primary uterine papillary serous carcinoma and non-Hodgkin''s lymphoma

Metachronous primary malignant tumors of uterine papillary serous carcinoma (UPSC) and non-Hodgkin's lymphoma (NHL) are rare. UPSC is a clinically aggressive and morphologically distinctive variant of endometrial carcinoma. We describe the clinical features of a 63-year-old patient with UPSC that was found 2 years after chemotherapy for malignant lymphoma of neck, stage IV and 5 months after radiation therapy for recurrence. This patient had undergone staging surgery and postoperative radiation for UPSC. One month after completion of radiotherapy, the patient expired due to persistence of the disease. The association between host immunity and UPSC is rarely described in the literature. Immunological profiles of this patient, with compositional changes of natural killer, B, and T cell, dramatically altered the percentage of CD4(+) T cell, CD8(+) T cell, and CD4/CD8 ratio, signifying depressed host immunity. Immunological profile of this patient stressed the issue of depressed host immunity and associated malignancies.     

Bone disease in primary biliary cirrhosis: Lack of association with distal renal tubular acidosis

Background and Aims: Primary biliary cirrhosis (PBC) might be complicated by osteoporosis, whose etiology remains unknown but seems to be multifactorial. Prevalence rates of 30% to 60% for distal renal tubular acidosis (DRTA) have been reported in PBC patients, generally as incomplete DRTA. Although it is undisputed that a reduced bone mineral density (BMD) is the expected outcome among patients who have been suffering from longstanding chronic metabolic acidosis, it is unclear if incomplete DRTA is also associated with metabolic bone disease in PBC patients. The present study was undertaken to compare the BMD of PBC patients with and without DRTA.
Methods: The BMD of 23 PBC patients (11 with DRTA and 12 without), all with normal clearance of creatinine, was assessed by dual energy radiograph absorptiometry. The diagnosis of DRTA was made if the urine pH was above 5.4 in all samples after the oral acid overload, showing tubular inability to acidify urine in the presence of test-induced systemic metabolic acidosis.
Results: Densitometric signs of osteoporosis were found in 82% of DRTA cases and in 83% of patients without DRTA (difference not significant). There were no significant differences in BMD measurement, T and Z scores of patients with and without DRTA.
Conclusions: The present study could not support a correlation between the presence of DRTA and the bone loss observed in PBC patients.     

58例多原发癌临床分析

Objective to Present 56 cases of multiple primary cancers,to make improvement of diagnosis and treatment.methods A total of 58 patients with multiple primary cancers admitted from 2003 to 2007 were analysed retrospectively in Beijing Tongren Hospital.Results Thirty-five cases were males,with sex ratio of male and female 1.5:1.The median age at the onset of the first disease was 61.5 years (ranged from 27 to 86).The onset age of the two primary cancers was mainly centered around 50～75 years,while half of the second cancers occurred within five years.Conclusion the treatment and prognosis of the two primary cancers are different from that of the recurred and metastatic malignancies and shoule be handled with care.     

Effect of a Low-Cost Intervention on Recording Body Mass Index in Patients'' Records

PURPOSE: Evaluate the effectiveness of body mass index (BMI) tables placed in exam rooms as an intervention to encourage providers to calculate and record BMI scores in patients' medical records. DESIGN: In a prospective cohort design, medical record data for 276 adult patients at a federally funded community health center in New England were examined from August 2000 to August 2002 following the intervention. METHODS: Prominent, multicolored, laminated BMI tables were posted in the exam rooms of one of the study site's three primary health care teams. Medical record data collected included documentation of BMI calculation in medical records, documentation of an obesity diagnosis, and inclusion of heights and current weights. Frequency distributions were calculated; chi-square tests were used to identify associations. FINDINGS: In contrast to the comparison teams, patients on the intervention team were more likely to have BMI recorded in the medical record. A statistically significant increase in the diagnosis of obesity was observed throughout the health center after the intervention. CONCLUSIONS: Posting BMI tables in exam rooms contributed to increased BMI documentation in patients' medical records.

Fumonisins as a possible contributory risk factor for primary liver cancer: A 3-year study of corn harvested in Haimen, China, by HPLC and ELISA

Employing HPLC fluorometry, gas-liquid chromatography (GLC) and a novel enzymelinked immunosorbent assay (ELISA) based on a monoclonal antibody, 40 corn samples, each collected in 1993 from agricultural stocks for human consumption in Haimen (Jiangsu County) and Penlai (Shandong Province), high- and low-risk areas for primary liver cancer (PLC) in China, respectively, were analysed for fumonisins (FBs), aflatoxins (AFs) and trichothecenes. Levels and positive rates of FBs and deoxynivalenol (DON) were significantly higher in Haimen than in Penlai. ELISA of the 40 corn samples harvested in the two areas in 1994 revealed that FB contamination levels and rates in these areas were comparable to those observed in 1993 in Haimen. ELISA analysis of 1993 and 1994 products revealed a wide occurrence of AFB₁ but the positive rates as well as levels were not significantly different between these areas. ELISA of the same sample number of corn harvested in 1995 revealed that FB contamination in Haimen was significantly higher than in Penlai. These 3-yearly surveys of corn samples (240 in total) demonstrated that corn harvested in Haimen was highly contaminated with FBs and that the contamination level, as well as positive rate in 1993 and 1995, were 10–50-fold higher than those in Penlai, suggesting FBs as a risk factor for promotion of PLC in endemic areas, along with the trichothecene DON. Co-contamination with AFs, potent hepatocarcinogens, was assumed to play an important role in the initiation of hepatocarcinogenesis.

Primary linitis plastica of the descending colon: A case report

A rare case of primary linitis plastica carcinoma of the colon seen in a 44 year old Japanese man is described herein. The patient had a complete obstruction of the descending colon and was treated with a loop colostomy followed shortly afterward by a left hemicolectomy. At the time of the second operation, the entire thickness of the colonic wall was found to be infiltrated by cancer cells, however, the other intraabdominal organs were free of cancerous involvement. The histopathological diagnosis made at this time was primary linitis plastica carcinoma of the descending colon. Nine months later, the patient developed an intestinal obstruction and relaparotomy revealed diffuse peritoneal dissemination. Two years after the first operation, upper GI films and a gastrofiberscopic examination revealed gastric involvement. The patient died 28 months after his initial operation, and autopsy revealed widespread metastases in the peritoneal surface, paraaortic lymph nodes, small intestine, remaining colon and stomach.
