From November 1981 to July 1985, 124 women with International Federation of Gynecology and Obstetrics (FIGO) stage III ovarian cancer were treated in prospective studies of surgery and chemotherapy in our institution. Patients with no macroscopic cancer after primary surgery (n = 16) received five cycles of adjuvant cis-platinum; those with residual cancer after primary laparotomy (n = 108) underwent a second surgical debulking after three or five cycles of cis-platinum-based cytoreductive chemotherapy. Total macroscopic tumor clearance was achieved in 26 of these 108 patients. Fourteen patients with total tumor excision at primary laparotomy remain in complete clinical remission a minimum of 36 months after diagnosis, but the median progression-free interval for the other two groups was 9 and 17 months, respectively. The survival for women who have total tumor clearance only at secondary surgery after chemotherapy is inferior to that for women with primary macroscopic tumor excision followed by chemotherapy.  相似文献

Surgery remains the initial treatment for patients with early-stage non-small-cell lung cancer (NSCLC). Additional therapy is necessary because of high rates of distant and local disease recurrence after surgical resection. Early trials of adjuvant chemotherapy and postoperative radiation were often plagued by small patient sample size, inadequate surgical staging, and ineffective or antiquated treatment. A 1995 meta-analysis found a nonsignificant reduction in risk of death for postoperative cisplatin-based chemotherapy. Since then, a new generation of randomized phase III trials have been conducted, some of which have reported a benefit for chemotherapy in the adjuvant setting. The role of postoperative radiation therapy remains to be defined. It may not be beneficial in early-stage NSCLC but still may have utility in stage IIIA disease. Improvement in survival outcomes from adjuvant treatment are likely to result from the evaluation of novel agents, identification of tumor markers predictive of disease relapse, and definition of factors that determine sensitivity to therapeutic agents. Some of the molecularly targeted agents such as the angiogenesis and epidermal growth factor receptor inhibitors are being incorporated into clinical trials. Preliminary results with gene-expression profiles and lung cancer proteomics have been promising. These techniques may be used to create prediction models to identify patients at risk for disease relapse. Molecular markers such as ERCC1 may determine response to treatment. All of these innovations will hopefully increase cure rates for lung cancer patients by maximizing the efficacy of adjuvant therapy.  相似文献

In 1980, second-look laparotomy was introduced simultaneously into the treatment regimen for ovarian carcinoma at the two main referral centers of northern Spain. First-line chemotherapy after initial surgery was, however, different at both hospitals. At one of them (Bilbao), a combination involving the use of cisplatin was employed (cyclophosphamide 600 mg/m2, Adriamycin 45 mg/m2, and cisplatin 80 mg/m2 i.v. on day 1), whereas the patients of the other hospital were treated mainly with single-agent chemotherapy (melphalan 0.2 mg/kg p.o. on days 1-5) and never with a cisplatin combination as first-line therapy in any case. In all, 92 patients (42 stage I, 14 stage II, 33 stage III, and 3 stage IV) could be treated during the study period with optimal surgery (complete tumor excision or largest residual tumor less than 2 cm in diameter). This was followed by adjuvant chemotherapy for 12-18 months in all cases, except for 18 patients with a stage Ia borderline or G1 tumor. The latter were merely kept under observation until their second-look laparotomy after 1 year of negative follow-up. All of the 74 patients who received adjuvant chemotherapy, of whom 36 with cisplatin and 38 without, were clinically disease free after at least twelve courses of treatment and had a second-look laparotomy performed. This was positive in 33.3% of the cases after cisplatin-containing therapy and in 26.3% of the cases after cisplatin-free therapy. This difference is not statistically significant. The mean follow-up period after negative second-look was 34 months. The long-term results of both patient groups were comparable as far as rate of positive second-look laparotomies and survival rate, overall and stage for stage are concerned. The use of cisplatin did not result in any significant therapeutic improvement. It was uniformly bad tolerated by the patients and carried higher cost, since all patients had to be hospitalized for treatment.  相似文献

Based on several landmark studies and meta-analyses, the standard of care for stage II - III A NSCLC patients has been adjuvant cisplatin-based doublet chemotherapy performed after appropriate surgical resection. The benefit of this therapy for patients with stage I B NSCLC is less apparent, likely because of the heterogeneity of this population. In Japan, however, many randomized clinical studies have assessed the effectiveness of postoperative adjuvant chemotherapy with tegafur-uracil (UFT)in patients with completely resected NSCLC. Based on these studies and a meta-analysis, UFT is used as the standard postoperative adjuvant chemotherapy for stage I NSCLC patients with a tumor larger than 2 cm. It is necessary to re-evaluate adjuvant chemotherapy strategies according to the new seventh edition of the tumor-nodemetastasis classification system. The role of postoperative radiotherapy(PORT)is also explored there. Recently, several tumor markers such as ERCC1 may have had a predictive value for selecting patients who will benefit from adjuvant platin-based chemotherapy. Targeted agents and vaccine therapy are also being evaluated as adjuvant treatments for use after the resection of NSCLC. Randomized studies are ongoing. If these results are confirmed, we will enter an era of personalized care for resected NSCLC.  相似文献

The prognostic importance of accurate staging of non-small cell lung cancer was established in 1974 and reaffirmed and refined in 1986. The concept of adjuvant therapy after pulmonary resection for lung cancer is justified by the behavior of the disease. The best available data pertinent to adjuvant therapy of lung cancer have been collected by The Lung Cancer Study Group over the past 13 years. These data are based on a commitment to prospective and standardized surgical staging as a basis for large-scale prospective randomized control trials. A treatment effect of combination chemotherapy has been detected for stage II and IIIA nonsquamous cancer and is suggested for squamous cancer as well. This treatment effect is of marginal clinical significance. Adjuvant therapy for stage I disease has not shown a detectable benefit. Adjuvant radiation therapy for stage II and IIIA squamous cell carcinoma likewise has not resulted in survival benefit. Systemic metastasis continues to be the major clinical problem in lung cancer treatment, and better systemic therapy is necessary to improve the outcome in this disease. However, some patients do benefit from adjuvant chemotherapy, and efforts to identify such patients prospectively are also the subject of current clinical research.  相似文献

The Ca755 solid tumor in the C57B1 mouse has been used as a model to study the interrelationship of surgery and adjuvant chemotherapy on primary tumor growth. Surgery was performed on various days after tumor implantation. Surgical mortality increased with delay in surgery. The mean survival time (MST) was significantly increased by surgery. An increased cure rate in mice with late surgery may be due to immunological factors. Pretreatment cytoxan chemotherapy prior to a number of surgical days on the most effect schedule increased MST in the later surgical days primarily due to shrinkage of tumor and a diminished surgical mortality. Posttreatment chemotherapy significantly increased MST primarily on the basis of reducing tumor cell population after surgery and increasing both the cure rate and the time until death of those mice dying of regrowth of tumor. Optimal chemotherapy alone significantly increased MST compared to untreated controls. Optimal postsurgery chemotherapy increased survival longer than the additive increase of chemotherapy alone and surgery alone. This paper illustrates relationships between day of surgery dose and schedule of chemotherapy and effect on various measurable parameters. The results can best be understood in relationship to each other. It is suggested that adjuvant chemotherapy has specific definable benefits. It is apparent from human studies that carefully devised designs which consider these interrelationships are necessary if optimal therapeutic results are to be achieved.  相似文献

Surgery remains the mainstay in curative therapy of stage I and II NSCLC and selected patients with stage III disease. The high rate of distant metastases occurring in patients after complete surgical resection demonstrates the need for effective adjuvant systemic therapy. However, outside of trials, (neo)adjuvant chemotherapy is currently not considered as an established standard in localized NSCLC. Postoperative radiotherapy increases local tumor control in completely resected N2 disease and after R1/R2 resections and is generally recommended in these situations. In inoperable patients radiotherapy offers the only chance of cure. Combined radiochemotherapy and the highly accelerated CHART radiotherapy have been shown to be superior to standard radiotherapy. Progress in the treatment of localized NSCLC over the last decades has been only modest and with the exception of favourable subgroups, prognosis of NSCLC remains grim. In the light of the high rate of local and distant metastases multidisciplinary approaches appear necessary in the vast majority of patients.  相似文献

It is well known that level of skin invasion and tumor thickness are significant prognostic factors in the evolution of primary melanoma. The prognosis of primary melanoma Clark III to V skin invasion level and more than 1.5 mm thick confirms this statement. Even the prophylactic dissection of regional lymph nodes has not improved results. In an attempt to obtain better results in the treatment of primary melanomas, a pilot trial was carried out combining surgery and adjuvant chemotherapy. A group of 21 patients with Clark III, IV and V level primary melanoma who underwent adjuvant polychemotherapy (velba + dactinomycin + procarbazine) for 1 year after surgery showed a very low incidence of recurrences (5%) after 24 months of observation. The historical control group, with the same level of tumor skin invasion, treated only surgically had in the same follow-up period a recurrence rate of 65%. This difference was statistically significant (p less than 0.01). All patients who received adjuvant chemotherapy survived 2 years whereas survival was 77% (p less than 0.05) in the surgical historical control group. Favorable results with the same protocol of adjuvant chemotherapy were not obtained in the group of 16 patients with stage II melanoma when compared with primary tumors. However, 4 recurrences were observed after 12 months of observation; toxic side effects of adjuvant chemotherapy were mild and tolerable. Considering the insufficient number of clinical trials with adjuvant chemotherapy, as well as sometimes controversial results, further randomized clinical studies are needed to establish the actual value of this conbined method in the treatment of primary melanoma with a high risk of dissemination.  相似文献

The occurrence of treatment-related hematologic malignancies after adjuvant therapy with alkylating agents for gastrointestinal cancers, ovarian carcinoma, and breast cancer and after treatment for Hodgkin's disease, non-Hodgkin's lymphoma, germ-cell tumors, and multiple myeloma has been well documented. Adjuvant chemotherapy is frequently used for the treatment of early stage breast cancer, and to date there has been no increase in the incidence of secondary myelodysplastic syndromes or acute leukemia after cyclophosphamide-based regimens when compared with surgical controls. This report describes two patients who developed acute myelocytic leukemia only after exposure to cyclophosphamide, methotrexate, and 5-fluorouracil adjuvant therapy. These two cases of acute leukemia, which developed 3 years after diagnosis of breast cancer and initiation of chemotherapy, were characterized by trilineage dysplasia and pancytopenia, and had abnormalities of chromosomes 5 and 7: characteristics consistent with treatment-related leukemia. Many women are diagnosed with early stage breast cancer each year who are potential candidates for adjuvant therapy. Although certain subgroups of patients have been shown to benefit from adjuvant therapy, continued efforts must be directed at identifying responders so that others will not be exposed to the additional risks of chemotherapy.  相似文献

Colon cancer is a common cause of cancer-related mortality. Complete surgical resection of the primary tumor and/or select metastatic lesions can be curative in many patients. The risk of recurrence after resection can be predicted by pathologic staging. Large prospective randomized trials over the past 2 decades have clearly shown an increased overall survival for patients with resected stage III colon cancer who are treated with adjuvant 5-fluorouracil-based chemotherapy. The benefit of adjuvant chemotherapy for patients with stage II disease remains controversial. There is indirect evidence to support adjuvant chemotherapy after resection of metastatic disease. Locoregional approaches such as radiation, hepatic arterial infusion, or portal vein chemotherapy remain investigational. Adjuvant immunotherapy with monoclonal antibodies is emerging as a therapeutic option that might complement chemotherapy. Future challenges include improving adjuvant chemotherapy with the addition and/or substitution of new agents, resolving which subset of patients with stage II and resected stage IV colon cancer might benefit from therapy, validating the benefit of immunotherapy, and investigating locoregional therapies compared with systemic therapy.  相似文献

Patients are not at risk of dying from a tumor that has been removed; they are at risk of dying from residual microscopic disease not removed at the time of operation. Thus, the goal of an adjuvant treatment, be it chemotherapy, radiation therapy, immunotherapy, or dietary and lifestyle manipulations, is to eradicate any residual, albeit microscopic, metastatic disease that might remain. Stage I disease carries an excellent prognosis, and at present there are no compelling data to support adjuvant chemotherapy for patients with this early stage. Stage II colon cancer also has a good prognosis after operation alone and represents the most complicated and contentious area in decisions regarding the use of adjuvant chemotherapy. Stage III colorectal cancer (TanyN???M?) represents a group at a higher risk of recurrence, and this population is routinely given adjuvant chemotherapy in the absence of a medical or psychiatric contraindication.  相似文献

PURPOSE: To determine patterns and predictors of concordance with institutional treatment guidelines among older women with breast cancer. METHODS: The study population included 1,568 patients aged 55 years and older who were treated at M.D. Anderson Cancer Center between July 1997 and January 2002 for stage I to IIIA invasive ductal and lobular breast cancer. Concordance with institutional guidelines was determined for definitive surgical therapy, radiotherapy after breast-conserving surgery, radiation therapy after mastectomy, adjuvant chemotherapy use, and adjuvant hormonal therapy use. The following variables were considered as possible modifiers of concordance: patient age, marital status, race, educational level, Eastern Cooperative Oncology Group performance status, comorbidity score, clinical stage, hormone receptor status, HER2-neu status, tumor grade, pathologic tumor size, lymphatic invasion, and number of lymph nodes involved. Logistic regression modeling was performed to determine the independent effect of each variable on guideline concordance. RESULTS: Older women were less likely to receive treatment in concordance with guidelines for definitive surgical therapy (P < .001), postlumpectomy radiation (P = .03), adjuvant chemotherapy (P < .001), and adjuvant hormonal therapy (P < .001). In multivariate analysis, age > or = 75 years predicted a deviation from guidelines for definitive surgical therapy, adjuvant chemotherapy, and adjuvant hormonal therapy. Nonwhite race was associated with decreased likelihood of adjuvant radiation therapy after breast conservation. CONCLUSION: After adjustment for comorbidity score, race, marital status, educational status, clinical stage, and tumor characteristics, increasing patient age was independently associated with decreased guideline concordance for definitive surgery, adjuvant chemotherapy, and adjuvant hormonal therapy. Future research should focus on delineating the possible reasons for guideline discordance.  相似文献

Gastric cancer is the most frequent tumor of the digestive tract in Mexico. Most patients are diagnosed at advanced stages, and fatal outcome is expected. One hundred fifty patient charts were retrospectively reviewed. Univariate and multivariate analyses were performed to evaluate the impact of clinicopathologic and treatment variables on survival. Most patients (75%) were at advanced stages, harboring poorly differentiated tumors. Surgery, mostly palliative, was performed on 114 patients. Chemotherapy was administered to 47 patients. On univariate analysis, significant prognostic factors were TNM stage, chemotherapy, surgical attempt, performance status, histology, and tumor site (p < 0.001). On multivariate analysis, independent prognostic factors were TNM stage, histology, tumor site, surgical attempt, and chemotherapy (p < 0.01). Median survival for patients with palliative or adjuvant chemotherapy was 11.4 and 10.4 months, respectively, compared with +/- 3 months for patients with no chemotherapy (p < 0.03). Nonsurgical patients receiving chemotherapy survived 5.4 months versus 1.1 months for those without chemotherapy. The favorable influence of chemotherapy persisted after a stratified analysis of subgroups eliminating potential biases. We identified prognostic factors for survival. Chemotherapy should be considered even for advanced-stage patients with either adjuvant or palliative attempts, because we consistently found a favorable impact on the median survival time. However, phase III prospective randomized trials are awaited.  相似文献

About 7200 pancreatic adenocarcinomas are diagnosed every year in France. In 80% of cases, a complete surgical resection of the tumor, which is the only treatment to provide a long-term survival to the patients, is not feasible due to locoregional or metastatic spread of the disease. After a surgical resection with a curative intent, the median overall survival does not exceed 12 to 20 months due to the tumor relapse. Hence, therapeutic trials have been developed using chemotherapy or chemo/radiotherapy as adjuvant/neoadjuvant treatments combined with surgery in order to achieve better long-term survival. It is now admitted that adjuvant chemotherapy may delay tumor relapse and even increase survival in a subset of patients (10%). This has yet not been demonstrated using chemoradiotherapy. Neoadjuvant treatment with chemo/radiotherapy, especially in patients with bordeline tumour, could increase the rate of resectability in a small number of patients, margin-free surgical resections, and local control of the tumor. These approaches need to be validated prospectively. Finally, in a small number of patients with locally advanced tumors being in good condition, the treatment with chemo/radiotherapy may allow to propose a secondary resection.  相似文献

IntroductionWith the results of studies on the timing of adjuvant treatment, it currently appears that adjuvant treatment should be initiated as soon as possible. Breast conserving surgery and oncoplastic surgery is being used with increasing frequency. Therefore, studies about whether or not these applications delay the adjuvant treatment are needed. The aim of this study was to determine the time period needed for adjuvant chemotherapy and radiotherapy of the patients with breast cancer and to reveal associated factors related to the patient, tumor, and surgical technique.Patients and MethodsTwo hundred eighty patients with breast cancer who had surgery and were given adjuvant treatments in our clinic were included in the study. Age, body mass index, concomitant diseases, smoking habits, menopausal status, neoadjuvant treatments, tumor characteristics, surgical technique, and surgical complications were recorded. The time period between surgery and initiation of chemotherapy and radiotherapy, the number of chemotherapy cycles, and the duration of chemotherapy and radiotherapy were calculated.ResultsThe numbers of patients who had modified radical mastectomy, breast conserving surgery, and oncoplastic surgery were 155 (55%), 47 (16.8%), and 78 (27.9%), respectively. The mean (SD) time period needed for chemotherapy administration was 19.5 ± 4.2 days (range, 13-41 days) and 3.9 ± 0.9 months for radiotherapy. Early wound complication of breast surgery was the only factor that delayed the adjuvant chemotherapy (P = .001).DiscussionIt has been well known that the time period between surgical treatment of breast cancer and adjuvant treatment affects survival. In our study, it has been shown that the surgical techniques used in breast and axillary surgery do not delay the initiation of adjuvant treatments. The adjuvant treatments of the patients who had oncoplastic surgery and breast conserving surgery were not delayed. The cooperation between the disciplines for the initiation of adjuvant treatments is important.  相似文献

Germ cell tumors of the ovary   总被引:1,自引:0,他引:1  
PURPOSE: Malignant ovarian germ cell tumors (MOGCTS) are rare but curable at all stages of disease. This review gives an outline of the management of this disease. METHODS: We performed a literature search in the PubMed of almost all relevant articles concerning MOGCTs on pathology, prognostic factors, surgery, post-operative therapy and late effects of therapy. The available literature is mainly composed of retrospective reviews and articles. RESULTS: Prognostic factors include stage, amount of residual tumor, histologic type and raised tumor markers. For patients with early stage disease, cure rates approach 100%, while for those with advanced-stage disease are at least 75%. Appropriate surgical treatment for patients where fertility needs to be preserved consists in laparotomy with unilateral salpingo-oophorectomy (USO) and resection of all visible disease. For patients with advanced-stage disease, the role and the extent of debulking surgery remain controversial despite its routine use. However, it is suggested a benefit from minimal residual disease at completion of primary surgical cytoreduction with both non-platinum and platinum-based chemotherapy regimens. Second-look surgery clearly is not indicated in patients with early stage non-dysgerminoma or in all patients with dysgerminoma. However, teratoma patients may benefit from secondary cytoreduction. Three courses of bleomycin, etoposide and cisplatin (BEP) is the current standard adjuvant chemotherapy and four courses of BEP are recommended in case of bulky residual tumor after surgery. More evidence is required to show that surveillance is a safe option. There is a hint that high-dose chemotherapy may play a role in relapsed patients. The majority of MOGCTs patients who undergo fertility-sparing surgery and chemotherapy retain their gonadal and reproductive function. There is an increasing concern about life-threatening long-term effects of treatment. CONCLUSION: MOGCTs are rare neoplasms that affect girls and young women and have excellent prognosis at all stages of disease with optimal therapy. The majority of MOGCTs patients retain their reproductive function.  相似文献

ABSTRACT: BACKGROUND: Adjuvant chemotherapy for stage III colon cancer is internationally accepted as standard treatment with established efficacy, but the usefulness of adjuvant chemotherapy for stage II colon cancer remains controversial. The major Western guidelines recommend adjuvant chemotherapy for "high-risk stage II" cancer, but this is not clearly defined and the efficacy has not been confirmed. METHODS: SACURA trial is a multicenter randomized phase III study which aims to evaluate the superiority of 1-year adjuvant treatment with UFT to observation without any adjuvant treatment after surgery for stage II colon cancer in a large population, and to identify "high-risk factors of recurrence/death" in stage II colon cancer and predictors of efficacy and adverse events of the chemotherapy. Patients aged between 20 and 80 years with curatively resected stage II colon cancer are randomly assigned to a observation group or UFT adjuvant therapy group (UFT at 500-600 mg/day as tegafur in 2 divided doses after meals for 5 days, followed by 2-day rest. This 1-week treatment cycle is repeated for 1 year). The patients are followed up for 5 years until recurrence or death. Treatment delivery and adverse events are entered into a web-based case report form system every 3 months. The target sample size is 2,000 patients. The primary endpoint is disease-free survival, and the secondary endpoints are overall survival, recurrence-free survival, and incidence and severity of adverse events. In an additional translational study, the mRNA expression of 5-FU-related enzymes, microsatellite instability and chromosomal instability, and histopathological factors including tumor budding are assessed to evaluate correlation with recurrences, survivals and adverse events. DISCUSSION: A total of 2,024 patients were enrolled from October 2006 to July 2010. The results of this study will provide important information that help to improve the therapeutic strategy for stage II colon cancer.  相似文献

In testicular cancer epidemiology, the increasing recognition that germinal epithelial atrophy is the final common pathway in the development of this tumor has developed along with reports that elevated follicule-stimulating hormone levels at the time of diagnosis of first tumor correlate with risk of developing a second tumor. There is also evidence from experimental studies that atrophy is a complication of vasectomy, a recently reported risk factor. In the area of new diagnostic approaches, correlation of the rate of rise of tumor markers after orchiectomy in patients with metastases has defined a new risk factor for predicting drug-resistant disease. In the treatment of nonseminoma, it has been reported that use of adjuvant chemotherapy for stage I tumors with two courses of combination chemotherapy produces a relapse rate lower than that seen after surgical staging. For seminoma, chemotherapy results have improved, with nearly 100% of patients cured by combination regimens and 80% cured by single-agent carboplatin. This success is finally leading to questioning of the role of radiotherapy as adjuvant therapy for stage I tumors. A study using two courses of adjuvant carboplatin produced equivalent results and possibly less toxicity.  相似文献

临床上有20%~25%的非小细胞肺癌(NSCLC)患者可手术治疗,但5年生存率也只有40%左右。辅助化疗是部分早期可切除肺癌的标准治疗方式,可使4%~15%的患者生存获益。但是,ⅠB期NSCLC是否能从辅助化疗中获益仍存在争议。近年来,多个临床研究评价了ⅠB期NSCLC辅助化疗的疗效,我们通过分析这些临床研究,寻找ⅠB期NSCLC的高危人群和辅助化疗的适应证。  相似文献

For every patient with locoregional circumscribed non-small cell lung cancer (NSCLC), consideration should be given to surgical management. The standard resection procedures for patients with sufficient functional reserve are lobectomy, extended lobectomy with bronchoplasty and/or angioplasty, bilobectomy, or pneumonectomy. Nonanatomic or atypical lung resections are only justified in exceptional cases for high-risk patients. Unaffected pulmonary lobes should be preserved and if necessary reanastomosed. There is no survival benefit gained by a resection that goes beyond radical removal of the macroscopically and microscopically visible tumor. Total ipsilateral lymph node dissection (interlobar, hilar, and mediastinal) completes every surgical treatment with curative intent. After the diagnosis of NSCLC has been made, the prognosis is poor. One year after the diagnosis 45% of the patients are alive, but after 5 years only 14% of the patients. If the subgroup of surgically cured patients with stage Ia disease is considered, the survival probabilities are 93% after 1 year and 70–80% after 5 years. In this respect, surgery for early stage NSCLC offers a well-founded prospect for cure. Additional adjuvant (postoperative) chemotherapy following complete resection (for patients with stage II NSCLC) can improve the survival probability by a further 4–15%. In general, the indication for or against surgery should result from careful interdisciplinary consultation that takes into account all factors of tumor extent and individual comorbidity. Inoperability should not solely be determined on the basis of expectations, but only by considering all of the individual patient factors.  相似文献
