Seventy-six patients with localized Ewing's sarcoma who received primary treatment at M.D. Anderson Hospital from 1948 through December 1975 were reviewed. Patients have been divided into four groups according to the different treatment regimens they received: Group I, moderate dose radiotherapy alone; Group II, high dose radiotherapy alone; Group III, radiotherapy plus vincristine and cytoxan; and Group IV, radiotherapy plus vincristine, Adriamycin, cytoxan and actinomycin. The problem of local recurrence appears to be solved with combined chemotherapy and radiation therapy with only one of 36 patients having a recurrence at the primary site in Groups III and IV. Multimodal therapy is the preferred treatment to obtain control of the primary lesion by radiation therapy while preserving good function. However, the major cause of failure remains distant metastases, 19 of 36 (53%) in Groups III and IV. In addition, 4 of 10 patients who have survived over 5 years have developed osteogenic sarcoma.  相似文献

The optimum management of localised intracranial germinoma remains controversial. Cure rates for this rare CNS tumour, which arises mainly in adolescents, exceed 90% at 10 years, and limitation of treatment-related late morbidity is therefore essential. Craniospinal radiotherapy plus boost is perceived to be the gold-standard treatment, but there have been suggestions that reduced-volume radiotherapy could be adequate for cure. We reviewed publications since 1988 to compare patterns of disease relapse and cure rates after craniospinal radiotherapy, reduced-volume irradiation alone (i.e., whole-brain or whole-ventricular irradiation followed by a boost), and focal or localised irradiation alone. The recurrence rate after whole-brain or whole-ventricular radiotherapy plus boost was 7.6% compared with 3.8% after craniospinal radiotherapy, with no predilection for isolated spinal relapses (2.9% vs 1.2%). We challenge the consensus that craniospinal radiotherapy is the best treatment for localised germinomas and conclude that reduced-volume radiotherapy plus boost should replace craniospinal radiotherapy when a radiotherapy-only approach is used.  相似文献

Tumor necrosis factor-alpha (TNF-alpha) enhances X-ray killing of human tumor cells in vitro and enhances tumor control when combined with radiotherapy (RT) in animal tumor models. In multiple Phase I studies, intravenous injection of TNF-alpha appeared to have severe systemic side effects. To overcome these limitations, we used a bispecific antibody (BAb) directed against carcinoembryonic antigen and human TNF-alpha to target this cytokine in human digestive carcinoma treated with simultaneous RT.We used human digestive carcinoma cell lines (colon cancer, LS174T, and pancreatic cancer, BxPC-3) to determine the interaction of TNF-alpha and RT on clonogenic cytotoxicity. Isobolograms were established to confirm additive or supra-additive effects between both treatments. LS174T and BxPC-3 cells were grafted subcutaneously at Day 0 into female nude mice (7-8 weeks old). When the tumors reached a volume of about 80 mm(3), the mice were randomly assigned to treatment: Group 1, normal saline i.v. injection (control group); Group 2, TNF-alpha at 1 microg/i.v. injection; Group 3, BAb at 25 microg/i.v. injection; Group 4, BAb plus TNF-alpha (ratio 25 microg to 1 microg) i.v. injection; Group 5, local RT plus normal saline (0.5 Gy. min(-1)) at a total dose of 30 Gy delivered in five fractions; Group 6, local RT plus TNF-alpha injections 3 h before RT; Group 7, local RT plus BAb plus TNF-alpha co-injected 24 h before RT. Tumor growth delay was used as the end point for all groups.In the LS174T experiments, TNF-alpha added 12 h before RT showed a statistically significant decrease in the survival fraction at 2 Gy compared with RT alone (0.23 vs. 0.42 Gy, p = 0.0017). These results were largely confirmed with the BxPC-3 cell lines (0.29 vs. 0.72, p <0.00001). Isobolograms confirmed the additivity between TNF-alpha and RT in both cell lines. At 50% survival, the data points were within the envelope of additivity. In the LS174T and BxPC-3 xenografts, RT as a single agent (Group 5) slowed tumor progression compared with Group 1 (p <0.027 and p = 0.00001, respectively). TNF-alpha alone, BAb alone, or BAb plus TNF-alpha (Groups 2, 3, and 4) had no effect. In the LS174T model, TNF-alpha plus RT enhanced the delay to reach 2000 mm(3) compared with RT alone but without statistical significance. This delay was significantly longer when BAb was added (p = 0.0033, for Group 6 vs. Group 7). In the BxPC-3 experiments, the median delay to reach 2000 mm(3) was similar between the RT and TNF-alpha plus RT groups (93 days). The use of our BAb in combination with TNF-alpha and RT dramatically enhanced this median delay (177 days, p = 0.0013). No body weight loss was observed in any group.Our data could be used as a solid preclinical rationale on which to base a clinical study of locally advanced pancreatic or rectal cancers in the near future.  相似文献

PURPOSE: Tumor necrosis factor-alpha (TNF-alpha) enhances radiotherapy (RT) killing of tumor cells in vitro and in vivo. To overcome systemic side effects, we used a bispecific antibody (BsAb) directed against carcinoembryonic antigen (CEA) and TNF-alpha to target this cytokine in a CEA-expressing colon carcinoma. We report the evaluation of this strategy in immunocompetent CEA-transgenic mice. METHODS AND MATERIALS: The murine CEA-transfected colon carcinoma MC-38 was used for all experiments. In vitro, clonogenic assays were performed after RT alone, TNF-alpha alone, and RT plus TNF-alpha. In vivo, the mice were randomly assigned to treatment groups: control, TNF-alpha, BsAb, BsAb plus TNF-alpha, RT, RT plus TNF-alpha, and RT plus BsAb plus TNF-alpha. Measurements of endogenous TNF-alpha mRNA levels and evaluation of necrosis (histologic evaluation) were assessed per treatment group. RESULTS: In vitro, combined RT plus TNF-alpha resulted in a significant decrease in the survival fraction at 2 Gy compared with RT alone (p < 0.00001). In vivo, we observed a complete response in 5 (50%) of 10, 2 (20%) of 10, 2 (18.2%) of 11, and 0 (0%) of 12 treated mice in the RT plus BsAb plus TNF-alpha, RT plus TNF-alpha, RT alone, and control groups, respectively. This difference was statistically significant when TNF-alpha was targeted with the BsAb (p = 0.03). The addition of exogenous TNF-alpha to RT significantly increased the endogenous TNF-alpha mRNA level, particularly when TNF-alpha was targeted with BsAb (p < 0.01). The percentages of necrotic area were significantly augmented in the RT plus BsAb plus TNF-alpha group. CONCLUSION: These results suggest that targeting TNF-alpha with the BsAb provokes RT curability in a CEA-expressing digestive tumor syngenic model and could be considered as a solid rationale for clinical trials.  相似文献

This study was designed to compare high-dose fractionated radiotherapy alone versus the same radiotherapy plus cisplatin in stage III non-small cell lung cancer (NSCLC). We randomly assigned 176 patients with stage III non-small cell lung cancer to one of two treatments; fractionated radiotherapy alone at dose of 64 Gy for 6-7 weeks (2 Gy given 32 times, in five fractions a week) or radiotherapy in the same schedule, combined with 20mg/m2 cisplatin 1 h before radiotherapy, given on days 1-5 of the second and sixth treatment weeks. The frequency of loco-regional progression was 68% among the patients who received radiotherapy plus cisplatin and 86% among those who received radiotherapy alone (P = 0.0001). The probability of survival free of disease after 3 years was 10% among the patients assigned to radiotherapy plus cisplatin and 0% among those treated only with radiotherapy (P = 0.0006). Overall survival at 3 years was 10% among those given radiotherapy plus cisplatin and 2% among those who received radiotherapy alone (P = 0.00001). Multivariate analysis demonstrated that radiotherapy plus cisplatin significantly improved loco-regional progression-free survival and overall survival, irrespective of radiation dose. The addition of cisplatin to fractionated radiotherapy prolongs loco-regional progression-free interval and survival in stage III non-small cell lung cancer.  相似文献

In the past, treatment for patients with early-stage Hodgkin lymphoma consisted mainly of radiotherapy. Now, chemotherapy alone and chemoradiotherapy are treatment options. These guidelines aim to provide recommendations on the optimal management of early-stage Hodgkin lymphoma. We conducted a systematic review searching MEDLINE, EMBASE, the Cochrane Library and other literature sources from 2003 to 2015, and applied the Grading of Recommendations Assessment, Development and Evaluation (GRADE). Two authors independently reviewed and selected studies, and appraised the evidence quality. The document underwent internal and external review by content, methodology experts, a patient representative and clinicians in Ontario. We have issued recommendations for patients with classical Hodgkin lymphoma and with nodular lymphocyte predominant Hodgkin lymphoma; with favourable and unfavourable prognosis; and for the use of positron emission tomography to direct treatment. We have provided our interpretation of the evidence and considerations for implementation. Examples of recommendations are: ‘Patients with early-stage classical Hodgkin lymphoma should not be treated with radiotherapy alone’; ‘chemotherapy plus radiotherapy or chemotherapy alone are recommended treatment options for patients with early-stage non-bulky Hodgkin lymphoma’; ‘The Working Group does not recommend the use of a negative interim positron emission tomography scan alone to identify patients with early-stage Hodgkin lymphoma for whom radiotherapy can be omitted without a reduction in progression-free survival’. Through the use of GRADE, recommendations were geared towards patient important outcomes and their strength reflected the available evidence and its interpretation from the patients’ point of view.  相似文献

Purpose: Hyperthermia induced by electrothermal needle (ETN) and electrochemical therapy (ECT) were combined (HECT) and the anti-tumor effect was evaluated.

Methods: Mice with Sarcoma180 were randomized into four different treatment groups: Control, ECT alone, Hyperthermia alone and HECT.

Results: The tumours in the HECT group were completely destroyed and they did not recur within a period of 10 days after treatment. However, tumour recurrence was found in six mice in the Hyperthermia group and five mice in the ECT group.

Conclusion: The HECT is a potentially effective way to treat solid malignant tumours.  相似文献
