OBJECTIVE: Although adjuvant therapy after surgery for non-small cell lung cancer (NSCLC) has been reported to be ineffective, it has been recently reported in prospective randomised studies conducted by two different groups in Japan that oral administration of a 5-fluorouracil (5-FU) derivative drug, UFT (a combination drug of tegafur and uracil) can improve the post-operative survival [The Study Group of Adjuvant Chemotherapy for Lung Cancer (Chubu, Japan). A randomized trial of postoperative adjuvant chemotherapy in non-small cell lung cancer (the second cooperative study). Eu J Surg Oncol 1995;21:69-77; Wada, H., Hitomi, S., Teramatsu, T, West Japan Study Group for Lung Cancer Surgery. Adjuvant chemotherapy after complete resection in non-small-cell lung cancer. J Clin Oncol 1996;14:1048-1054]. To examine the efficacy of UFT as post-operative adjuvant therapy, a retrospective study was performed. METHODS: A total of 655 consecutive patients who underwent complete tumor resection for pathologic stage I-IIIa, NSCLC at the Department of Thoracic Surgery, Chest Disease Research Institute, Kyoto University between 1976 and 1992 were retrospectively reviewed. As post-operative adjuvant therapy, UFT was administrated to 98 patients (UFT group), and was not administered to the other 557 patients (Control group). RESULTS: The 5-year survival rate of the UFT group was 76.5%, which was significantly better than that of the Control group (5-year survival rate: 58.6%, P = 0.005). Stratified with pathologic stage, the efficacy of UFT was seen in the p-stage I disease (5-year survival rate: 88.6% for the UFT group, 72.0% for the Control group, P = 0.013) and in the p-stage IIIa, pN2 disease (5-year survival rate: 54.3% for the UFT group, 37.5% for the Control group, P = 0.037). Multivariate analysis of the prognostic factors also revealed the efficacy of UFT (P = 0.004, 95% confidence interval of relative risk: 0.325-0.840). Post-operative intravenous chemotherapy or radiation therapy did not prove to be significant factors affecting the prognosis. CONCLUSIONS: Efficacy of oral administration of UFT as post-operative adjuvant therapy for completely resected NSCLC was proposed. To confirm the efficacy, a prospective randomized study for a more homogenous patient group is needed.  相似文献

Thirty-four patients with advanced gastric cancer were treated with combination chemotherapy employing Tegafur-Uracil (UFT), etoposide, Adriamycin, and Cisplatinum (CDDP) (UFT-EAP therapy). An objective partial response was obtained in 16 patients (47%) and the median duration of remission was 12.2 months. The 50% survival time for all 34 patients was 10 months. Patients with moderately or well differentiated adenocarcinoma responded well (13/19, 68%), while those with undifferentiated adenocarcinoma showed a poor response (3/15, 20%). Six responding patients were noted to have no evidence of viable cancer at the primary site by endoscopic biopsy, and underwent gastrectomies. The resected specimens showed complete disappearances of the primary tumors in four patients. The median survival time for the patients receiving gastrectomies was 24 months. The regimen was very well tolerated, apart from moderate bone marrow suppression. Our results suggest that patients with advanced gastric cancer can be effectively treated with UFT-EAP chemotherapy.  相似文献

Combination chemotherapy with CDDP and 5-FU is one of the effective regimens for head and neck cancer. We studied the difference in the effects and adverse effects between two kinds of schedules of CDDP administration for CDDP-5-FU combination chemotherapy. For 13 patients, CDDP was administered on 5 consecutive days from day 1 to day 5 at a daily dose of 16 mg/m2 (Regimen A). For 14 patients CDDP was administered 80 mg on day 1 (Regimen B). 5-FU was administered 700 mg/m2/ day as a continuous drip infusion for 120 hours from day 1 to day 5. For regimen A, the response rate was 77%; for regimen B, it was 64%. The pattern of adverse effects showed a difference. Regimen B was more toxic for renal function than regimen A. But regimen A showed toxicity for bone marrow function. Acute phase nausea and vomit appeared more frequently in regimen B. The difference in the adverse effect pattern, which depends on the schedule of CDDP administration, seems important in order to apply this regimen for head and neck cancer patients safely. The schedule of CDDP administration should be changes depending on the renal and bone marrow function of patients. In order to evaluate the efficacy of UFT as adjuvant chemotherapy, UFT was administered p.o. to patients with maxillary sinus carcinoma for more than one year after definitive treatment with surgery or radiotherapy. Fifteen patients with UFT adjuvant chemotherapy showed significantly better survival rates than patients without adjuvant chemotherapy. We also studied adjuvant chemotherapy with CBDCA and FT for patients with advanced head and neck cancer. Administration with UFT (600 mg/day) from day 1 to day 14 with CBDCA 350 mg/m2 at day 7 was repeated more than twice. This regimen showed low toxicity and better survival for nasopharyngeal cancer patients. More clinical trials with this regimen for adjuvant chemotherapy are needed.  相似文献

BACKGROUND: For patients with invasive bladder cancer the usual recommended treatment is radical cystectomy, although transurethral resection of the tumor, systemic chemotherapy, and radiotherapy are each effective in some patients. We sought to determine whether these treatments in combination might be as effective as radical cystectomy and thus might allow the bladder to be preserved and the cancer cured. METHODS: We enrolled 53 consecutive patients with muscle-invading bladder cancer (stages T2 through T4, NXM0) in a trial of transurethral surgery, combination chemotherapy, and irradiation (4000 cGy) with concurrent cisplatin administration. Urologic evaluation of the tumor response directed further therapy: radical cystectomy in the 8 patients who had incomplete responses, additional chemotherapy and radiotherapy (6480 cGy) in the 34 patients who had complete responses or who were unsuited for cystectomy, and alternative care in the 11 patients who could not tolerate either irradiation or chemotherapy. RESULTS: After a median follow-up of 48 months, 24 of the 53 patients (45 percent) were alive and free of detectable tumor. In 31 patients (58 percent) the bladder was free of invasive tumor and functioning well, even though in 9 (17 percent) a superficial tumor recurred and required further transurethral surgery and intravesical drug therapy. Of the 28 patients who had complete responses after initial treatment, 89 percent had functioning tumor-free bladders. CONCLUSIONS: Conservative combination treatment may be an acceptable alternative to immediate cystectomy in selected patients with bladder cancer, although a randomized clinical trial that included a group for simultaneous comparison would be required to produce definitive results.  相似文献

PURPOSE: The standard treatment for patients with muscle-invasive carcinoma of the urinary bladder is radical cystectomy. While radical cystectomy cures many patients with this tumor, almost 50% of them will develop metastatic disease. Adjuvant chemotherapy has been proposed for these patients in an attempt to reduce the probability of relapse and to improve survival. To assess whether adjuvant chemotherapy does benefit patients with muscle-invasive bladder cancer, we reviewed all phase II and III studies published in the English literature over the last 20 years. METHODS: A review of all published reports was facilitated by the use of Medline computer search and by manual search of the Index Medicus. RESULTS: Several comparative, nonrandomized studies have indicated that adjuvant chemotherapy may prolong disease-free survival. Four randomized studies have been conducted and all had a suboptimal patient accrual. Three studies used a cisplatin-containing combination chemotherapy and included primarily patients with non-organ-confined transitional-cell carcinoma (TCC) of the bladder. All three studies indicated that adjuvant chemotherapy improved disease-free survival and two of them also showed improvement in event-free survival and overall survival, respectively. CONCLUSION: Published series have been unable to establish an undisputed benefit of adjuvant chemotherapy over radical cystectomy alone for muscle-invasive bladder cancer. The interpretation of the available data is compromised by several methodologic and statistical problems. Thus, adjuvant chemotherapy cannot be considered as a standard treatment for all patients with muscle-invasive carcinoma of the bladder. Well-designed prospective randomized studies are needed to clarify the role of adjuvant chemotherapy in this disease. However, outside a protocol setting, there is some evidence that patients with extravesical disease or with lymph node involvement may benefit from adjuvant treatment with cisplatin-based combination chemotherapy. No data support such an approach for patients with muscle-invasive but organ-confined bladder cancer.  相似文献

BACKGROUND: The results of palliative chemotherapy with cyclophosphamide, methotrexate and 5-fluorouracil (CMF) in patients with advanced breast cancer who received adjuvant therapy with the same regimen were investigated. RESULTS: Of 47 patients, 14 (30%) achieved an objective remission (median duration 9.5, range 5-21 months) and 8 (17%) stabilisation of disease (median duration 6, range 3-17 months). Objective remissions were observed in premenopausal as well as in postmenopausal women, in patients with all categories of dominant localisation of disease and regardless of the oestradiol receptor status of the primary tumour or eventual previous endocrine therapy. One of 4 and 13 of 43 patients who started palliative chemotherapy within or later than 12 months after the last adjuvant course obtained an objective remission. The median survival time from start of therapy of all treated patients was 12 (range 1-40) months. Patients with an objective remission or stable disease and patients with progressive disease had a median survival time of 20 (range 6-40) and 6 (range 1-35) months respectively (p < 0.0001). CONCLUSIONS: Palliative treatment with CMF should not be rejected for patients who have relapsed after adjuvant chemotherapy with the same modality.  相似文献

A prospective randomized trial was conducted to evaluate the efficacy of long-term oral administration of low-dose tegafur combined with uracil as an adjuvant chemotherapy, following transcatheter arterial embolization (TAE) in 40 patients with hepatocellular carcinoma (HCC). Forty eligible patients were randomized into two groups: 20 with TAE plus UFT (a compound of tegafur 200 mg and uracil 448 mg per day) and 20 with TAE alone. A good necrosis rate or decrease in size of more than 70% of the original tumor mass was attained in 10 by TAE plus UFT arm and in 12 by TAE arm alone. As for the "responded" patients, there was no significant difference in the time from tumor response to tumor regrowth between the two groups. The appearance rate of ascites and/or encephalopathy in patients with chemotherapy was slightly higher than that in control patients. The median survival time was 22.7 months for TAE plus UFT arm and 28.2 months for TAE arm alone. There was no significant difference in the cumulative survival curves. In conclusion, these results indicated no substantial benefit for this chemotherapy regimen, as an adjuvant therapy for patients with HCC during repeated TAE.  相似文献

In the mid-1980s, trials of adjuvant therapy for colon cancer in the United States had a "no treatment" arm, which reflected the belief that effective adjuvant chemotherapy did not exist for patients with surgically resected disease at high risk for recurrence. However, with the observation in the early 1990s that postsurgical adjuvant 5-FU plus levamisole reduced tumor recurrence and ultimately increased overall survival in stage III colon cancer, the potential of effective adjuvant chemotherapy was realized. Questions about the duration of adjuvant chemotherapy, the specifics of chemotherapy schedule/drug selection, and its use in stage II colon cancer are beginning to be clarified in large, randomized adjuvant therapy trials. In rectal carcinomas, combined modality postoperative pelvic irradiation plus chemotherapy for stage II and III disease has been shown to reduce both local and systemic recurrences and to prolong survival compared with that in patients treated with local surgery and radiation. Again, large randomized trials are attempting to clarify both the optimal chemotherapeutic agents and schedules to be used and also whether preoperative combined modality therapy can improve the resectability rate, rate of sphincter preservation, and survival. Future trials will examine new agents shown to be effective in advanced disease as well as monoclonal antibodies, such as MoAb 17-1A, that may have selective activity in minimal disease. Improvement in overall survival remains the ultimate endpoint of future adjuvant therapy trials; however, trials will also critically examine toxicity, quality of life, pharmacoeconomics, and genetic and biologic correlates that may help select more appropriate candidates for adjuvant therapies.  相似文献

A clinical study was performed on the efficacy of intraarterial chemotherapy using reservoir system for far-advanced urological malignancy. The reservoir system was indwelled in the femoral subcutaneous layer using Seldinger's method. Fifteen cases with inoperable complicated advanced bladder cancer and ten cases with postoperative local recurrent bladder cancer received intraarterial chemotherapy using the reservoir system. Then, 23 cases with local relapsed prostate cancer and two cases with endocrine-resistant prostate cancer received chemotherapy. The administered anti-cancerous agents were methotrexate, cis-platinum and adriamycin, and 5-FU or carboplatin were administered as maintenance therapy. The mean courses of chemotherapy were six for bladder cancer and four for prostate cancer. During stabilization of the local lesion, no distant deterioration was recognized. Overall clinical efficacy was as follows: PR:18 cases and NC:7 cases for bladder cancer; then, PR:11 cases and 14 cases for prostate cancer. The median duration of stabilization was as follows: 23 months for bladder cancer and 12 months for prostate cancer. Complications were fewer than with systemic chemotherapy.  相似文献

The 5 year cancer specific survival rate of advanced prostate cancer, especially in metastatic cancer is less than 40%. Recently, maximum androgen blockade showed some beneficial effects in cases of minor disease but no additional usefulness in major cases. The treatment modality referred to as initial chemoendocrine, used to treat prostate cancer, seems to be a reasonable method because prostate cancer cells contain heterogeneity. This procedure means that the endocrine treatment is best suited to treat hormone sensitive cells, whereas chemotherapy is more appropriately used as a firstline therapy for hormone insensitive cells. We reported that the initial chemoendocrine method showed superiority in the 5 year cancer specific survival category than in the endocrine therapy analyzing non-randomized trials. From that stage on we reviewed the beneficial point of the treatment, and are now trying randomized control studies.  相似文献

PURPOSE/OBJECTIVES: To review the incidence, pathophysiologic mechanisms, treatment options, and nursing care of patients with bladder cancer. DATA SOURCES: Published articles, book chapters, American Cancer Society materials, and a computerized data base. DATA SYNTHESIS: Nearly 53,000 cases of bladder cancer will be diagnosed this year. Recent studies link mutations on the p53 gene and abnormalities on chromosome 9 to bladder cancer. Seventy percent of patients present with local tumors within the bladder. Surgery and intravesical chemotherapy are the most common treatments for superficial bladder cancer. Deeply invasive disease sometimes can be cured by surgery, irradiation, or a combination of treatment modalities. Early stage detection has a 91% survival rate. Prevention strategies include smoking cessation and reduction of the risk of occupational exposure to toxic chemicals. CONCLUSIONS: Bladder cancer is a prevalent disease with significant morbidity. IMPLICATIONS FOR NURSING PRACTICE: Knowledge about bladder cancer will help nurses prevent and manage the disease and its treatment complications and meet patients' psychological needs.  相似文献

We assessed the actuarial survival of 28 patients with localized prostate cancer who were treated with endocrine therapy in comparison with that of 19 patients who had radical prostatectomy between 1972 and 1995. There were no significant differences among the cause-specific curves and clinical disease-free survival of patients treated with endocrine therapy and radical prostatectomy but the all-cause survival curves favored the surgery group. The results of endocrine therapy alone were unsatisfactory for the patients with high grade tumors. In conclusion, the patients with localized prostate cancer at high risk of death from other complications are reasonable candidates for endocrine therapy.  相似文献

The role of radiation therapy in the management of bladder cancer continues to be controversial. Attention to the issue of response to treatment, instead of overall survival, ultimate local control and quality of life, has hampered progress in determining the optimal-treatment strategy for patients with bladder cancer. Although the heterogeneity of bladder cancer has been recognized for some time now, the trend has been to seek one cure for all, rather than to use the available modalities selectively and optimally. The use of continent urinary diversion has made cystectomy more acceptable, but no form of diversion is as satisfying as a natural, well functioning bladder. The case against definitive XRT has been built on the lack of total radiosensitivity of transitional cell carcinoma. It is interesting that the lack of total chemosensitivity of bladder cancer and total curability with surgery has not prevented those modalities from being widely used. The recognition of the systemic nature of invasive bladder cancer has appropriately led to increased attention to the control of systemic disease. However, this has led to, at times, compromised local therapy. The use of primary or adjuvant chemotherapy should not impede the pursuit of optimal local therapy in patients with bladder cancer with the emphasis on the optimal quality of life. In parallel, the goal of bladder preservation and improved quality of life should not overshadow the importance of local tumor control. Because metastatic bladder cancer currently is an almost universally lethal disease, we should optimize the use of effective treatment modalities to achieve modest improvements in cure rate. The idea that definitive radiation therapy has no role in the management of bladder cancer exists in the minds of those who hold strong convictions and see an alternative view to their own as being controversial. We believe that attention should not focus on this controversy but on the recognition of the reality that the best management of bladder cancer is a shared responsibility among the oncologists of all disciplines. With this recognition, clinical research toward improving outcome for patients with bladder cancer will move forward.  相似文献

PURPOSE: The rationale for using adjuvant chemotherapy in colorectal cancer is to achieve better disease control and thus reduce the high rates of tumor recurrence and mortality in patients who undergo curative surgery. The current literature, including relevant abstracts, on clinical trials of fluorouracil (5-FU) in combination with high-dose leucovorin as adjuvant chemotherapy for colorectal cancer is reviewed. The intent is not to present new data, but to present the reader with a broad perspective and larger patient experience on which to base well-reasoned treatment decisions. DESIGN: Published clinical trials and abstracts presented at the 1996 American Society of Clinical Oncology (ASCO) meeting that assessed 5-FU in combination with high-dose leucovorin as adjuvant chemotherapy for colorectal cancer were surveyed. End points of interest were disease-free survival (DFS), overall survival, and toxicity. RESULTS: In randomized trials that used high-dose leucovorin at doses that ranged from daily-times-five 200 mg/m2 to weekly 500 mg/m2 in combination with 5-FU, significant improvements in both DFS and overall survival were observed over surgery alone (control). In patients treated with high-dose leucovorin/5-FU, DFS rates ranged from 71% to 77% compared with control (58% to 64%). A similar trend was seen in overall survival, with a range of 75% to 84% compared with control (63% to 77%). Toxicities observed for high-dose leucovorin administered on a weekly or daily-times-five schedule were diarrhea, stomatitis, myelosuppression, and nausea. CONCLUSION: Overall, the results of these randomized trials support the use of high-dose leucovorin/5-FU as adjuvant therapy for colorectal cancer. Longer follow-up studies are needed to compare the benefits of these different regimens in terms of survival and to characterize adverse effects, especially those that may not be immediately evident. Adjuvant therapy with high-dose leucovorin/5-FU is an effective regimen that is well tolerated by many patients with colorectal cancer.  相似文献

Twenty-six patients with advanced colorectal cancer were treated with UFT and leucovorin (LV). On day 1, patients received LV 500 mg/m2 in IV infusion, followed by 15 mg/12 h for 13 days. On days 1 to 14, patients took oral UFT twice daily. Three cycles were given every 28 days, unless grade III-IV toxicity appeared. The initial dose of UFT (200 mg/day) was increased until 800 mg/day. Dose limiting toxicities were stomatitis, diarrhea and epigastralgia. The maximum tolerated dose of UFT was 390 +/- 10 mg/m2. Three out of 24 evaluable patients achieved a partial response and 1 a complete response with UFT doses of 260 to 390 mg/m2. These results warrant confirmation in phase II studies.  相似文献

To demonstrate the trend and treatment outcome of rectal cancer after the advent of adjuvant therapy, all case notes of rectal cancer patients admitted to Chulalongkorn Hospital from 1985-1994 were reviewed and cases were followed until 1996. Mean follow-up period was 685.3 days (8-3, 193 days). Most rectal tumors were Dukes' C (43.8%), well-differentiated (54.1%) and at the distal third (53.4%). AP resection remained the most common procedure before and after the advent of adjuvant therapeutic options (62.3%). Of 146 patients treated by curative operations, 60 had adjuvant therapies of which radical radiotherapy with or without chemotherapy was the most common. However, chemotherapy was increasingly employed as the neoadjuvant and as combined chemoradiotherapy. There was a preferential selection of less well-differentiated, more distal, more Dukes' C disease and younger patients for the adjuvant therapy (p < 0.05). Recurrence rate in the adjuvant group was not different from the surgery group despite significant poorer prognostic indicators (17.4% & 21.7%, p = 0.53). Mortality was higher in Dukes' B + C patients in adjuvant group (17.3% & 3.4%, p = 0.02). The outcomes were not different among Dukes' A patients. The complications; i.e. wound problems, gut obstruction; did not increase with the adjuvant treatment. No adverse effect was observed on the healing of colorectal or coloanal anastomoses in the adjuvant group.  相似文献

Recent observations and our experience that histologic types of gastric cancer related significantly to patterns of recurrence prompted us to develop intraoperative and postoperative chemotherapy based on the preoperatively diagnosed histologic types of cancer and to evaluate its effectiveness by a prospective randomized trial. This chemotherapy regimen consisted of the intraoperative administration of mitomycin C (MMC) and postoperative administration of cisplatin (80 mg/patient, day 14), and tegaful and uracil (UFT) (300-600 mg/day for 2 years). Patients with a diffuse type of cancer were randomly assigned to one of three treatment groups: no intraoperative chemotherapy and UFT 300 mg/day (P0 group, n = 16); intraoperative chemotherapy and UFT 300 mg/day (P1 group, n = 13); or UFT 600 mg/day (P2 group, n = 17). Patients with an intestinal type of cancer were randomly assigned to one of three treatment groups: H0 (n = 17), H1 (n = 12), and H2 (n = 12); each group was subjected to the same protocols as the P0, P1, and P2 groups, respectively, except for the MMC administration route. MMC (10 mg/patient) was administered intraoperatively into the intraperitoneal cavity (P1 and P2 groups) or the portal vein (H1 and H2 groups). All patients underwent curative resection. Background factors did not differ significantly among the treatment groups. The overall survival rates were progressively worsened in the order of P2, P1, and P0 or H2, H1, and H0, respectively. The survival rate of the P2 group was statistically higher than that of the P0 group (p < 0.05). The intermediate-term survival rate of the P2 group or H2 group was significantly higher than that of the P0 group (p < 0.05) or H0 group (p < 0.05), respectively. These results suggest the effectiveness of this therapy and the possible eradication of potential micrometastatic foci outside the surgical field by the direct administration of chemotherapeutic agents to the predicted recurrence site.  相似文献

Surgical operation remains the most effective method of treatment for patients with cancer of the large bowel. However, innovative surgical techniques have not improved survival rates for colorectal cancer in 25 years. Attempts at increasing survival with chemotherapy as an adjunct to surgical procedures remain inconclusive and controversial. Many adjuvant chemotherapy trials have failed to recognize those prognostic factors-such as nodal involvement, serosal penetration, vascular or perineural invasion, and microscopic invasion at margins of resection-that characterize certain patients at high risk for recurrent cancer. Failure to include only high risk patients in adjuvant chemotherapy is, in part, responsible for the lackluster performance to date. For rectal cancer, preoperative irradiation increases the chances of cure with surgical operation by reduction of pathologic staging, but it has not increased survival in patients with persistent nodal involvement. Immunotherapy is a possibly valuable method of treatment; however, it is clinically untested. An adjuvant immunotherapy protocol for high risk patients is described.  相似文献

OBJECTIVE: To evaluate the prognosis of stage pT3bM0 invasive urothelial bladder tumours treated by cystectomy alone or combined with adjuvant chemotherapy according to the MVAC protocol (methotrexate, vinblastine, adriamycin and cisplatin). MATERIAL AND METHODS: From 1987 to 1996, 90 patients with stage pT3M0 urothelial bladder tumours were treated with isolated cystectomy (n = 69) or followed by MVAC chemotherapy (n = 21). Lymph node stage was N0 (n = 55), N+ (n = 29) or Nx (n = 6). Essentially selected because of their good general status, patients treated with chemotherapy had a lymph node stage N0 (n = 7) or N+ (n = 14). Chemotherapy had to be suspended in 2 cases and with a fatal outcome during treatment in 4 cases, due to tumour progression, surgical complication or bone marrow aplasia. RESULTS: 65 deaths have occurred with a follow-up of 2 to 120 months (m = 15), including 2 postoperative deaths, 39 cancer deaths and 14 intercurrent deaths. The 1-year, 2-year and 5-year actuarial survival rates were 70%, 48% and 19% for stage N0 and 54%, 25% and 3% for stage N+, respectively, with corresponding median survivals of 20 and 12 months (p < 0.005). The recurrence rate increased from 40% at stage N0 to 62% at stage N+ (p = 0.05), and the corresponding recurrence-free survivals were 16 months and 7 months (p < 0.02). The median survival without chemotherapy ranged from 11 months at stage N+ to 20 months at stage N0 and, with chemotherapy, from 19 months at stage N+ to 67 months at stage N0. The median recurrence-free survival with and without chemotherapy, was 43 months and 17 months at stage N0 and 12 months and 7 months at stage N+. CONCLUSION: The prognosis after cystectomy for stage pT3b bladder cancer is severe, especially in the presence of lymph node involvement. Adjuvant chemotherapy according to the MVAC protocol tends to improve survival, especially recurrence-free survival, and appears beneficial at stage N0. However, the value of this adjuvant treatment, which is associated with a high specific morbidity appears to be more relative at stage N+.  相似文献

Two hundred consecutive patients with presumed localized prostate cancer had radical prostatectomy alone (n = 119) or were treated for an average period of 3 months with combination therapy using the antiandrogen flutamide and one luteinizing hormone-releasing hormone (LHRH) agonist (Lupron or Zoladex). The positive margins decreased from 35.3% in the group undergoing prostatectomy alone to 11.5% in the group of men who received combination therapy before radical prostatectomy. In 41 apical tumors, the incidence of positive margins decreased from 50% in the control group to 18.6% in the combination therapy group. In stage C disease, the incidence of positive tumor showed a tendency to decrease with the extended duration of endocrine treatment with a rate of 37.5% after 3 months and 16.7% after 6 months. Whether the decreased incidence of positive surgical margins will all translate into prolonged survival remains to be verified by long-term follow-up of these patients. However, the initial results obtained in the present study are very encouraging.  相似文献
