OBJECTIVE The present study was designed to evaluate the epidemiological and prognostic significance of proteinuria in patients with gastric cancer (GC).METHODS We retrospectively reviewed the frequency of proteinuria in patients with GC and analyzed its relationship with the GC biological characteristics, treatment and survival.RESULTS Proteinuria incidence in GC patients was 24.06%, which was significantly higher than that found in a control group (P<0.01); the frequency of proteinuria was significantly correlated with an advanced disease stage(P<0.01). We also found that the post-treatment mean value of proteinuria was remarkably lower than the pre-treatment value (P<0.001). KaplanMeier analysis revealed a significant correlation between proteinuria and survival of GC patients (P<0.05). Multivariate analysis demonstrated that the TNM stage, lymph node status and proteinuria may serve as independent prognostic markers in patients with GC (P <0.01).CONCLUSION A high prevalence of increased urinary protein excretion was observed in GC patients complicated with nephritis. Proteinuria may be used as one of the prognostic markers for patients with GC. 相似文献

A chemoimmunotherapy program designed on the basis of experimental results was administered to 27 patients with stage III carcinoma of stomach following curative resection. The treatment regimen consisted of active immunotherapy with Vibrio cholerae neuraminidase (VCN)-treated autologous tumor cells admixed with bacillus Calmette-Guérin (BCG) and chemotherapy with drugs such as cyclophosphamide (CY), mitomycin C (MMC), and 5-fluorouracil (FU) which proved to enhance the immune response when administered at optimal dose and timing. Then, it was followed by long-term administration of tegafur (FT) and immunomodulators. This treatment significantly improved survival when compared to that of 41 historical control patients treated with surgery alone (P less than 0.001). As compared to 31 control patients concurrently treated with a bolus dose of MMC followed by long-term FT and immunomodulators, survival had a tendency, but not significantly, to be improved in patients treated with this therapy (P less than 0.1). However, the survival rate at 4.5 years was significantly higher than that of control patients (P less than 0.01). These results appeared to show that this type of adjuvant combination chemoimmunotherapy may be of benefit for this group of patients with gastric carcinoma. 相似文献

BACKGROUND: Patients who present with stage IV gastric cancer are not commonly managed with surgical resection as effective palliation can usually be accomplished with systemic chemotherapy, endoscopic stenting, or surgical bypass procedures. Given the inherent morbidity and mortality associated with gastrectomy, palliative resection for stage IV gastric cancer should be reserved for ideal surgical candidates who are most likely to benefit from the procedure. The purpose of this study is to review outcomes following resection for stage IV gastric cancer, and to identify criteria predictive of improved outcomes following gastrectomy in this setting. METHODS: A retrospective review of a prospective GI oncology database was conducted. Sixty-three patients with stage IV gastric cancer managed with surgical resection between 1989 and 2001 were identified. Variables including demographic data, patterns of distant spread (ex: peritoneal, lymphatic, hematogenous), location of tumor, and type of gastrectomy were utilized to conduct survival analyses. RESULTS: Actuarial survival for all patients at one and 3-year intervals was 52% and 12%, respectively. Improved survival was observed for patients of East Asian race (median survival 20 vs. 12 months, P < 0.05, students t-test) and age less than 60 years (median survival 15 vs. 12 months, P < 0.05). This trend was also illustrated by Kaplan-Meier survival analysis. Other variables including pattern of distant spread, location of tumor, and type of gastrectomy were not associated with a significant difference in survival. Both East Asian race and age less than 60 years were statistically significant predictors of improved survival when assessed by univariate regression analysis. When variables were analyzed in a multivariate regression analysis, Asian race and age <60 both lost their statistical significance as independent predictors of improved survival. CONCLUSIONS: Long-term survival for patients with stage IV gastric cancer who are managed with surgical resection is achievable. Patient specific variables including East Asian race and age less than 60 years appear to be associated with prolonged survival when assessed by comparison of means, Kaplan-Meier analysis, and univariate regression analysis. However, multivariate regression analysis failed to demonstrate these factors as independent predictors of improved outcome. In conclusion, highly selected acceptable risk surgical candidates with stage IV gastric cancer should be considered for management with surgical resection in clinically appropriate scenarios. 相似文献

Clinical stage after preoperative chemoradiation is a better predictor of patient outcome than the baseline stage for localized gastric cancer 总被引:2,自引:0,他引:2

BACKGROUND: For patients with localized gastric cancer (LGC) who are receiving preoperative chemoradiation (CTRT), the postsurgical pathologic stage predicts overall survival (OS) better than the baseline stage. The authors hypothesized that presurgical (postCTRT) stage would also correlate better with patient outcome than the baseline stage. METHODS: The authors analyzed 74 LGC patients treated with preoperative CTRT receiving similar treatment. Patients were staged with baseline endoscopic ultrasonography (EUS) and laparoscopy. Patients received induction chemotherapy, then CTRT (45 Gy), and had an attempted surgery. After CTRT, patients had complete preoperative staging including EUS in 35 patients. RESULTS: Thirty-five had all 3 sets of staging, baseline, presurgical, and postsurgical. Baseline stage did not associate with OS (P = .16) nor disease-free survival (DFS; P = .13). However, presurgical stage was associated with OS (P = .01), and DFS (P = .05). OS was also associated with postsurgical stage and was longer for stages 0 and I than for stages III and IV (P = .01 and .04, respectively). Similarly, DFS was longer in postsurgical pathologic stages 0, I, and II than in stage III or IV (P < .001, <.001, and <.01, respectively). Baseline staging did not correlate with the proportion of patients alive at 4 years; however, presurgical staging did. Patients with stage I or II survived longer than those with stage III or IV (81% vs 25%; P < .01). CONCLUSIONS: Heterogeneity in clinical biology of LGC is best reflected after CTRT in presurgical and postsurgical pathologic stages rather than by the baseline stage. Correlation of outcome with presurgical staging may facilitate strategies to individualize therapy for LGC. 相似文献

Background. We investigated retrospectively the usefulness of polysaccharide K (PSK) administration for prolonging survival after noncurative
resection in patients with stage IV gastric cancer who underwent surgery at our department.
Methods. 357 patients with gastric cancer evaluated as stage IV according to thegeneral rules for gastric cancer study, 11th edn (1985) of the Japanese Research Society for Gastric Cancer, who were expected to succumb to surgical death or postoperative
death within 2 months were studied. The patients were divided into two groups: total PSK dosage greater than or less than
180g. Survival rates were calculated for each group.
Results. In these stage-IV gastric cancer patients, the 5-year and 10-year survival rates in the PSK group were both 13.9%. In the
non-PSK group, the rates were 8.7% and 7.0%, respectively. The survival rates were significantly higher in the PSK group (p
= 0.0001). The survival rate was also calculated with respect to the staging factors. Patients in the PSK group who had H0,
P0, se or milder and n3 or n4 showed a significantly higher survival rate than those with these staging factors in the non-PSK
group (p = 0.010).
Conclusion. PSK administration prolonged survival in stage-IV gastric cancer patients, the effect being marked in patients with severe
lymph node metastasis. We suggest that be administered as adjuvant therapy in stage-IV gastric cancer patients with severe
lymph node metastasis (n3, n4). 相似文献

Mortality for gastric cancer in elderly patients 总被引:10,自引:0,他引:10
BACKGROUND: The aim of this study was to clarify the surgical outcome in elderly patients with gastric cancer. METHODS: The clinicopathological features of elderly patients (80 (3.7%), over 80 years, elderly group) were reviewed retrospectively and compared with those of younger patients (2095 (96.3%), 23-79 years, control group). RESULTS: The elderly group had a significantly higher prevalence of concomitant disease (P < 0.0001), while the prevalence of T1 primary tumor, N0 lymph node metastasis, and stage I was lower (P = 0.0125, P = 0.0004, P < 0.0001). The rates of resected cases and curative operation (R0) were significantly lower in the elderly group (P < 0.0001, P = 0.0021). The mortality from other diseases was 16.3% in elderly patients and 4.4% in control patients (P < 0.0001). The 5-year survival of stage I and stage IV were not significantly different between the two groups (P = 0.1266 and P = 0.2490). The overall survival and disease-specific survival for all patients in the elderly group were significantly lower than those in the control group (P < 0.0001, P = 0.0102). However, disease-specific survival for resected cases was not significantly different between the two groups (P = 0.0725). CONCLUSIONS: In elderly patients, the reason for the poor prognosis is the high rate of advanced stage and the high rate of death from other diseases. 相似文献

BACKGROUND AND OBJECTIVES: The incidence of gastric cancer is increasing in the elderly. The aim of this study is to evaluate the impact of advanced age (> or =80 years) on morbidity, mortality and late outcome after curative surgery for gastric cancer. METHODS: The cases of 30 octogenarians (Group A) with gastric cancer who underwent surgical treatment in our Institution from 1990 to 2003 were reviewed and compared to a simultaneous group of 228 younger patients (Group B). RESULTS: The rate of resective and curative procedures was not different in the two groups, although the American Society of Anaesthesiologists (ASA) risk was significantly higher in the elderly (P < 0.001) and the lymphatic dissection was less extended in group A. In the two groups, the curability was directly correlated to the cancer stage, but not affected by the ASA risk. The postoperative morbidity and mortality rates were similar in the two groups and were not related to the ASA risk. Considering the mortality for gastric cancer alone, the two groups showed a similar survival rate, only correlated to the cancer stage. CONCLUSIONS: In the elderly, an oncologically correct surgical procedure can safely be prosecuted with satisfactory immediate and late results. 相似文献

In the interval from 1941-1981 when 1887 patients with gastric cancer were seen at The University of Texas System Cancer Center M.D. Anderson Hospital and Tumor Institute, 151 curative and 45 palliative total gastrectomies or esophagogastrectomies were performed. Over the same interval, 21 patients with extent of primary and metastatic tumor roughly comparable to that seen in the palliative resection group were treated by exploration only or, infrequently, by attempted bypass. In individual patients subtle differences in extent of disease as well as differences in philosophy of the operating surgeon regarding the value of palliative resection undoubtedly contributed to the procedure selected. Survival after curative resection was greater than after palliative resection which in turn was greater than survival after exploration bypass (P less than or equal to .0006). Operative mortality fell significantly in CR patients in the interval 1970-1981 compared to 1941-1969 and was significantly lower than in the PR group in the interval 1970-1981 (P less than or equal to 0.01). Five-year survival increased significantly (P less than or equal to 0.03) in the CR group when results in the two time intervals were compared but not in other groups. 相似文献

PURPOSE: To compare cisplatin-cyclophosphamide versus carboplatin-cyclophosphamide as primary chemotherapy for stage III (suboptimal) and stage IV ovarian cancer. PATIENTS AND METHODS: Three hundred forty-two patients were randomly assigned to treatment with six courses of intravenous (i.v.) cisplatin 100 mg/m2 plus i.v. cyclophosphamide 600 mg/m2, or i.v. carboplatin 300 mg/m2 plus i.v. cyclophosphamide 600 mg/m2. RESULTS: The estimated median survivals were 17.4 and 20.0 months for the cisplatin and carboplatin study arms, respectively. The null hypothesis of a 30% survival superiority with the cisplatin arm was rejected at the P = .02 level. Clinical response rates were 52% for the cisplatin arm and 61% for the carboplatin arm. Pathologic complete response rates were similar for both study arms. There was less thrombocytopenia on the cisplatin arm (P less than .001); however, there was less nausea and emesis (P less than or equal to .001 for courses 1 to 5), renal toxicity (P less than .001), anemia (P = .01), hearing loss (P less than .001), tinnitus (P = .01), neuromuscular toxicities (P = .001), and alopecia (P less than .001) on the carboplatin arm. CONCLUSION: Carboplatin-cyclophosphamide proved to have a significantly better therapeutic index than cisplatin-cyclophosphamide in patients with stage III (suboptimal) and stage IV ovarian cancer. 相似文献

BACKGROUND AND OBJECTIVES: Despite precipitous drop in the incidence of gastric carcinoma in Japan, it is still one of the leading causes of death associated with malignant disease. Once the contiguous organs are involved the prognosis becomes dismal. Prognostic factors governing the survival of patients with T4 gastric carcinoma remain unclear. METHODS: Between 1980 and 1998, 150 patients were treated for T4 gastric carcinoma. Results and prognostic factors were evaluated by univariate and multivariate analyses. RESULTS: With a 73% resectability, patients with tumor resection had a significantly (P < 0.0001) improved survival rate. Within an acceptable operative mortality (2.6%), apparently curative cases had survival benefit (P < 0.0001) over noncurative cases. In the multivariate analysis, the death risk increased by 2.18 (relative risk) when splenectomy was spared from the operative procedure (P < 0.0071). Presence of esophageal invasion was the other independent prognostic factor in T4 gastric carcinoma patients (relative risk 2.11). Conventional prognostic factors along with the type of organs invaded by the carcinoma had no impact on prognosis. CONCLUSIONS: Patients with T4 gastric carcinoma might be benefited from aggressive surgery with a curative intent. Whenever possible, splenectomy should be done along with invaded organ resection. 相似文献
