BACKGROUND: Ewing sarcoma family of tumors (ESFT) of bone is extremely rare in Japan. The objectives of the current study were to assess the clinical outcome and prognostic factors of patients with ESFT of bone in Japan and to compare them between Euro-American and Japanese populations. METHODS: The authors conducted a retrospective analysis of 243 patients who were treated for ESFT of bone in Japan between 1981 and 2003. Local therapy was surgery in 35% of patients, surgery combined with radiotherapy in 40% of patients, radiotherapy alone in 22% of patients, and no local treatment in 3% of patients. All but 3 patients received various regimens of multidrug chemotherapy. RESULTS: The median patient age was 16 years. The primary disease sites were the trunk in 53% of patients and the extremities in 47% of patients. Forty-one patients had metastases at presentation. The median follow-up was 66 months. A univariate survival analysis demonstrated that patients who had metastases at presentation, primary site in the trunk, age >or=16 years, tumor size >or=10 cm, tumor that responded poorly to induction chemotherapy, and local treatment with radiotherapy alone had a significantly worse event-free survival (EFS). A multivariate analysis further verified that the former 3 factors were significant adverse prognostic factors. Of 201 patients with localized disease, 45 patients who received current chemotherapy regimens that included ifosfamide and etoposide had a significantly better 5-year EFS rate (67.6%) compared with other patients. CONCLUSIONS: The clinical outcome of patients with localized ESFT of bone in Japan has improved markedly with the use of current chemotherapy regimens that include ifosfamide and etoposide and has become comparable to the outcomes observed in other major series of Euro-American patients. The prognostic factors are also almost identical. 相似文献

BACKGROUND: Advances in the treatment of Ewing sarcoma family of tumors (ESFT) are the result of improvements in systemic and local therapies. The individual contributions of each treatment component cannot be analyzed separately; improvements in local and systemic control can influence each other. PATIENTS AND METHODS: We reviewed the records of 220 patients treated on institutional protocols from 1979 to 2004. Factors predictive of local and distant recurrence were analyzed. RESULTS: The median age at diagnosis was 13.7 years. Ninety-five patients relapsed at a median of 1.6 years. The 5-year overall survival estimate was 63.5% +/- 3.5%. The estimated 5-year cumulative incidence (CI) of local failure was 25.1% +/- 3.0%. Local failure was associated with treatment era (P < 0.001), tumor size (P = 0.037) and type of local control (P = 0.021). Systemic treatment intensification improved local control. The estimated 5-year CI of distant recurrence was 22.5% +/- 2.9%. Patients with localized disease (P < 0.001), smaller tumors (P = 0.018) and those who received surgery +/- radiation for local control (P = 0.023) had lower CI of distant failure. CONCLUSIONS: Successful treatment of ESFT requires optimal systemic and local therapy. Both treatment modalities are intertwined and the control of both local and distant disease is the result of the combined approach. 相似文献

AimsData on metastatic Ewing's sarcoma family of tumours (ESFT) with uniform chemotherapy protocol are minimal.Materials and methodsThis was a single institutional patient review of patients treated between June 2003 and November 2011 and evaluated on an intent-to-treat analysis. All patients received uniform chemotherapy: neoadjuvant chemotherapy (NACT), surgery and/or radiotherapy as local treatment followed by adjuvant chemotherapy. Local treatment was offered if the patient achieved a complete response and/or a partial response at both the primary and the metastatic site.ResultsIn total, 150/374 (40%) ESFT patients were metastatic, with a median age of 15 years (range: 2–50); a tumour diameter of 10 cm (range: 1.8–26). Most common metastatic sites were lung only (53; 35%), bone only (35; 23%) and combined bone/lung (25; 17%). Twenty patients underwent surgery; 55 patients received radical radiotherapy after NACT. After a median follow-up of 26.1 months (range: 1.6–101.6), 5 year event-free survival (EFS), overall survival and local control rate (LCR) were 9.1 ± 3.3%, 16.9 ± 5.2% and 31.8 ± 7.9%, respectively. Univariate analysis showed serum albumin ≤3.4 g/dl (P < 0.001) to predict inferior EFS. Tumour size >8 cm (P = 0.05), haemoglobin ≤10 g/dl (P = 0.04), hypoalbuminaemia (P = 0.003) and radical radiotherapy as local treatment (P = 0.03) predicted inferior overall survival. No factor significantly predicted LCR, although age ≤15 years (P = 0.08) and radical radiotherapy as local treatment (P = 0.09) had a trend towards inferior LCR. Hypoalbuminaemia was the only prognostic factor to predict EFS on multivariate analysis.ConclusionThis was the largest study of metastatic ESFT from Asia and identified a unique prognostic factor. In view of dismal prognosis with conventional chemotherapy in metastatic ESFT with hypoalbuminaemia, palliative intent therapy may be a potential therapeutic alternative for this subgroup of patients, especially in resource-challenged situations. 相似文献

BACKGROUND: Aim of our study was to evaluate the efficacy of multiagent intensive preoperative chemotherapy in patients with Ewing sarcoma family tumors (ESFT), in order to succeed a better percentage of necrosis before surgical resection. PROCEDURE: Eighteen patients with ESFT were treated with the same multiagent intensive preoperative protocol. 5/18 patients had bone Ewings sarcoma (EWS) and 13/18 had peripheral primitive neuroectodermal tumor (PNET). None had metastases at diagnosis. Chemotherapy consisted of 5 or 6 cycles with vincristine, cisplatin, cyclophosphamide, and Adriamycin, followed by 12 cycles of vincristine, cyclophosphamide, and actinomycin-D. Five patients with EWS underwent total resection after 5-6 cycles of preoperative chemotherapy and prosthetic replacement was performed in two of them. In 3/13 patients with PNET the tumor was resected at diagnosis and in 1/13 after 5 cycles of chemotherapy, while 9/13 patients received chemotherapy only and/or radiotherapy. RESULTS: In patients with EWS, the histologic specimens of the resected tumors showed that tissue necrosis was 100% in four patients and 95% in one patient. The good histologic response reflects the effectiveness of this regimen in all ESFT. No patient had topical recurrence or developed metastatic disease during follow-up period (2-13 years, mean time 7.4 years). All patients had the scheduled cycles without delays or dose reductions. There were no major side effects of chemotherapy. CONCLUSIONS: The intensive chemotherapy schedule, comprising of 5-6 cycles preoperatively, seems to maximize the percentage of tumor necrosis, thus improving outcome. Our study implies that this combined therapy may improve the prognosis of ESFT. 相似文献

This study was designed to confirm the previously observed favorable survival rates and prognostic factors in young children with nonmetastatic medulloblastoma (MB) treated with postoperative chemotherapy alone. Patients who received a diagnosis during the period January 2001 through December 2005 and who were aged <4 years received 3 cycles of postoperative systemic multiagent chemotherapy and intraventricular methotrexate. In cases of complete remission, treatment was terminated after 2 additional cycles of chemotherapy. Otherwise, secondary surgery, radiotherapy, and consolidation chemotherapy were recommended. At a median follow-up of 4.5 years, the 5-year event-free survival (EFS) and overall survival (OS) rates (± standard error) for 45 patients (median age, 2.5 years) were 57% ± 8% and 80% ± 6%, respectively. Nineteen patients with desmoplastic/nodular MB variants had better 5-year EFS and OS rates (90% ± 7% and 100% ± 0%, respectively) than did 23 patients with classic MB (30% ± 11% and 68% ± 10%, respectively; P < .001 for EFS; P = .008 for OS). Five-year EFS and OS rates for 3 children with anaplastic MB were 33% ± 27%. Desmoplastic/nodular histology was an independent prognostic factor for EFS. Twenty-nine of 30 patients without postoperative residual tumor remained in continuous complete remission. Our results confirm that histology of MB variants is a strong prognostic factor in this age group. Sustained tumor control can be achieved by this chemotherapy regimen in young children with desmoplastic/nodular MB variants. For children with non-desmoplastic/nonnodular MB variants, for which predominantly local relapses lead to less favorable survival rates, local radiotherapy has been introduced after chemotherapy since 2006. 相似文献

PURPOSE: Final results are presented from two consecutive European studies for patients with metastatic rhabdomyosarcoma (RMS) to identify prognostic variables and determine the value of high-dose chemotherapy (HDCT) in complete remission. PATIENTS AND METHODS: A total of 174 patients aged 3 months to 18 years participated. From 1989 to 1991, patients received four cycles of intensive multiagent chemotherapy. From 1991 to 1995, patients achieving complete remission received consolidation with HDCT. All received local therapy (surgery, radiation therapy) according to response. RESULTS: At a median follow-up of 8 years, 5-year overall survival (OS) and event-free survival (EFS) for the whole group were 24% and 20%, respectively. No statistical difference was found between HDCT and standard chemotherapy (5-year OS, 36% v 27%; EFS 29% v 23%). Univariate analysis identified primary tumor in parameningeal, extremity, or other sites; age younger than 1 year and older than 10 years; bone or bone marrow metastases; multiple metastases; and multiple sites of metastases as unfavorable prognostic factors for OS and EFS. Multivariate analysis identified unfavorable site, bone or bone marrow involvement, and unfavorable age as independently unfavorable factors. Two subgroups were identified. Those with fewer than two unfavorable factors had 5-year EFS and OS of 40% and 47%, respectively. Patients with > or = two unfavorable factors had 5-year EFS and OS of 7.5% and 9%, respectively. CONCLUSION: A minority of patients with metastatic RMS have better survival than overall results for this population suggest. Those in the highest risk group have such poor survival that they are candidates for first-line novel therapies. There is no evidence that consolidation with HDCT improves outcome. 相似文献

Evaluation of chemotherapy response in pediatric bone sarcomas by [F-18]-fluorodeoxy-D-glucose positron emission tomography 总被引:12,自引:0,他引:12
BACKGROUND: Response to neoadjuvant chemotherapy is a significant prognostic factor for osteosarcoma (OS) and the Ewing sarcoma family of tumors (ESFT). Conventional radiographic imaging does not discriminate between responding and nonresponding osseous tumors. [F-18]-fluorodeoxy-D-glucose (FDG) positron emission tomography (PET) is a noninvasive imaging modality that accurately predicts histopathologic response in patients with various malignancies. To describe the FDG PET imaging characteristics and to determine the correlation between FDG PET imaging and chemotherapy response in children with bone sarcomas, we reviewed our single institution experience. METHODS: Thirty-three pediatric patients with OS or ESFT with osseous primary sites were evaluated by FDG PET. All patients received standard neoadjuvant chemotherapy. FDG PET standard uptake values before (SUV1) and after (SUV2) chemotherapy were analyzed and correlated with chemotherapy response assessed by histopathology in surgically excised tumors. Twenty-six patients had SUV1, SUV2, and surgical excision. RESULTS: Although the mean SUV1 in children with OS or ESFT were similar (8.2. vs. 5.3, P = 0.13), mean SUV2 for OS patients was greater than the values for ESFT patients (3.3 vs. 1.5, P = 0.01). All ESFT patients and 28% of OS patients had a favorable histologic response to chemotherapy (>or= 90% necrosis). Combining ESFT and OS patients, both SUV2 and the ratio of SUV2 to SUV1 (SUV2:SUV1) were correlated with histologic response (P = 0.01 for both comparisons). CONCLUSION: FDG PET evaluation of pediatric bone sarcomas demonstrated significant alteration in response to neoadjuvant chemotherapy. SUV2 and SUV2:SUV1 correlated with histopathologic assessment of response and potentially could be used as a noninvasive surrogate to predict response in patients. 相似文献

BACKGROUND:
Aggressive fibromatosis (AF) is a rare tumor of intermediate malignancy that has a strong potential for local invasiveness and recurrence. To date, there are no general recommendations for the clinical management of pediatric AF.METHODS:
The authors retrospectively analyzed 94 patients aged ≤21 years, including 23 patients who underwent complete surgery (Group I), 42 patients who underwent incomplete surgery with microscopic residual tumor (Group II), and 29 patients who underwent either biopsy or macroscopically incomplete surgery (Group III).RESULTS:
The 5‐year event‐free survival (EFS) and overall survival rates were 44% and 99%, respectively. Local recurrences developed in 22% of patients in Group I, in 76% of patients in Group II, and in 76% of patients in Group III. Two of 7 patients with abdominal disease died of tumor progression, whereas none of the patients with extra‐abdominal AF died of their disease. Systemic treatment was given to 15 patients as first‐line treatment and to 34 patients at time the time they developed recurrent disease: The response rate was 47% in the former patients and 50% in the latter patients. Objective responses were observed in 11 of 19 patients who received combined methotrexate plus vinblastine/vinorelbine, in 7 of 15 patients who received alkylating‐agent chemotherapy, and in 4 of 11 patients who received other therapies (tamoxifen, sulindac, interferon alfa).CONCLUSIONS:
The current analysis suggested that the clinical course of AF in children may resemble that of AF in adults. Local recurrences did not affect the chance of responding to systemic therapy or the survival rate. The completeness of initial resection was the main factor that influenced EFS, whereas disease control after marginal resection was much the same as that achieved after intralesional surgery/biopsy. Good responses to systemic treatments, and particularly to low‐dose chemotherapy, were observed as reported previously in adults. Cancer 2010. © 2010 American Cancer Society. 相似文献9.

PURPOSE: Cooperative Ewing's Sarcoma Study (CESS) 86 aimed at improving event-free survival (EFS) in patients with high-risk localized Ewing tumor of bone. PATIENTS AND METHODS: We analyzed 301 patients recruited from January 1986 to July 1991 (60% male; median age 15 years). Tumors of volume >100 mL and/or at central-axis sites qualified patients for "high risk" (HR, n = 241), and small extremity lesions for "standard risk" (SR, n = 52). Standard-risk patients received 12 courses of vincristine, cyclophosphamide, and doxorubicin alternating with actinomycin D (VACA); HR patients received ifosfamide instead of cyclophosphamide (VAIA). Tumor sites were pelvis (27%), other central axis (28%), femur (19%), or other extremity (26%). The initial tumor volume was <100 mL in 33% of cases and > or =100 mL in 67%. Local therapy was surgery (23%), surgery plus radiotherapy (49%), or radiotherapy alone (28%). Event-free survival rates were estimated by Kaplan-Meier analyses, comparisons were done by log-rank test, and risk factors were analyzed by Cox models. RESULTS: On May 1, 1999 (median time under study, 133 months), the 10-year EFS was 0.52. Event-free survival did not differ between SR-VACA (0.52) and HR-VAIA (0.51, P =.92). Tumor volume of >200 mL (EFS, 0.36 v 0.63 for smaller tumors; P =.0001) and poor histologic response (EFS, 0.38 v 0.64 for good responders; P =.0007) had negative impacts on EFS. In multivariate analyses, small tumor volumes of <200 mL, good histologic response, and VAIA chemotherapy augured for fair outcome. Six of 301 patients (2%) died under treatment, and four patients (1.3%) developed second malignancies. CONCLUSION: Fifty-two percent of CESS 86 patients survived after risk-adapted therapy. High-risk patients seem to have benefited from intensified treatment that incorporated ifosfamide. 相似文献

Background and purpose
Local treatment for non-metastatic Ewing’s sarcoma family tumors (ESFTs) is controversial. Results achieved in a single institution in patients with ESFT of the humerus are presented.Materials and methods
Patients treated between 1983 and 2000 for ESFT of the humerus were included. The impact of local treatment (surgery, radiotherapy or both) on outcome was assessed.Results
55 patients: 34 males (62%); 21 females (38%); mean age: 17.9 (range: 3-40). Local treatment: surgery in 27 patients (49%), radiotherapy in 17 (31%) and surgery followed by radiotherapy in 11 (20%). After a mean follow-up of 15 years (range: 7-25 years), 27 patients (49%) remained continuously disease free, 27 (49%) relapsed and one died of chemotherapy toxicity. The local recurrence rate was 13% overall: 18% (3/17) after radiotherapy, 7% (2/27) after surgery and 19% (2/11) after surgery followed by adjuvant radiotherapy (p = ns). On the contrary, the 10-year EFS resulted significantly higher after surgery (64%) than radiotherapy (18%, p < 0.01). The 10-year EFS after surgery followed by radiotherapy was 45%, non-significantly different from EFS of surgery or radiotherapy alone. The 3 treatment groups had a similar distribution of the most important prognostic variables for ESFT, except for the tumor-bone ratio, which was higher for patients who underwent radiotherapy, and surgical margins, more frequently inadequate in patients treated with a combination of radiotherapy and surgery compared to those managed by surgery alone.Conclusions
In conclusion this study shows that in EFST of the humerus surgery is the best treatment for small tumors. Large tumors are probably best treated with surgery too, as long as good functional results and quality of life can be expected, and adequate surgical margins are achievable. Postoperative radiotherapy is mandatory when margins are inadequate. A high local control rate, of more than 80%, can be obtained also by means of radiotherapy alone. 相似文献12.

BACKGROUND: To determine the local control, survival, and functional outcome of local excision plus postoperative therapy for patients with rectal cancer. METHODS: A total of 39 patients underwent a local excision (2 with snare excision of a T1 polyp and 37 with full-thickness local excision) followed by postoperative radiation therapy +/- 5-FU-based chemotherapy. The median follow-up was 41 months, and 11 patients had positive margins. RESULTS: The 5-year actuarial colostomy-free survival was 87% and overall survival was 70%. Crude local failure increased with T stage: 0% T1, 24% T2, and 25% T3. Of the 8 patients (21%) who developed local failure, 5 underwent salvage APR and were locally controlled. Actuarial local failure at 5 years was 31% for T2 disease and 27% for the total patient group. In the 32 patients with an intact sphincter, 94% had good to excellent sphincter function. CONCLUSION: Although local failure in patients with T2 tumors has increased since our prior report, the survival, sphincter function, and local salvage rates are acceptable. Local excision and postoperative therapy remains a reasonable alternative to APR in selected patients. 相似文献

PURPOSE: To assess the results and morbidity of treatment of children with localized pelvic neuroblastoma (NB). PATIENTS AND METHODS: All consecutive cases of localized pelvic NB registered in the French multicenter prospective studies NBL90 and NBL94 between 1990 and 1999 were reviewed. Resectability was decided on the basis of clinical and radiologic evaluation. In unresectable tumors, primary chemotherapy (combinations of carboplatin-etoposide and vincristine-cyclophosphamide-doxorubicine) was administered before surgery. RESULTS: Forty-seven children (with 26 resectable tumors and 21 unresectable) were included in this study. At the end of treatment, 31 children were in complete remission (66%). Long-term neurologic sequelae were observed in seven patients (15%), directly attributable to surgery in three cases. After a median follow-up of 48 months (range, 13 to 129 months), 44 patients are alive. Six children experienced local relapse; four of these children achieved subsequent remission. The projected overall survival and event-free survival (EFS) rates at 5 years are, respectively, 93% +/- 4% and 84% +/- 5%. Survival of children treated with preoperative chemotherapy are similar to those treated by primary surgery (80% and 88% respectively). The extent of surgical resection seemed to have no influence on the outcome (EFS rates 76% and 89% in case of gross residue and complete resection or microscopic residue, respectively). CONCLUSION: Our data confirm the excellent survival of localized pelvic NBs. Considering the efficacy of preoperative chemotherapy, patients with pelvic NB should be carefully screened for primary surgery. The risk of neurologic impairment during radical excision should be balanced with the good survival of children with minimal residual disease. 相似文献

BACKGROUND: Malignant fibrous histiocytoma (MFH) is a controversial entity. In the current study, the authors reviewed their institutional experience with these tumors to characterize their clinical features in pediatric patients and assess the impact of surgical resection on outcome. METHODS: The records of the 28 patients who were diagnosed with MFH or MFH variants of soft tissue between January 1971 and December 2000 were reviewed and the tumors were reclassified according to the World Health Organization guidelines. RESULTS: Seventeen patients had MFH; 10 patients had angiomatoid fibrous histiocytoma (FH), and 1 patient had a plexiform fibrohistiocytic tumor. The median age of patients at the time of diagnosis was 7.3 years. The most common primary tumor site was the extremity (n = 14). Metastatic disease (to the lung) was present in only three patients, each of whom had MFH. Of the 17 MFH tumors, 13 were high grade, 8 were invasive, and 6 measured > 5 cm. All angiomatoid FH tumors and the plexiform fibrohistiocytic tumor were noninvasive, and 10 measured < or = 5 cm. Surgical treatment was comprised of wide local excision with clear margins (n = 18), amputation (n = 3), excision with positive or indeterminate surgical margins (n = 4), partial resection (n = 2), or biopsy only (n = 1). Primary reexcision was performed for 21 patients. The 5-year survival and event-free survival (EFS) estimates for patients with MFH were 76.5% +/- 11.2% and 70.6% +/- 12.1%, respectively; the 5-year survival and EFS estimates were 100% +/- 0% for patients with angiomatoid FH or plexiform fibrohistiocytic tumor. Compared with partial resection or excision, wide local excision or amputation was found to have a positive impact on the probability of EFS in patients with localized disease (P = 0.008). All four patients with metastatic or unresectable MFH had died by the time of last follow-up. CONCLUSIONS: MFH should be distinguished from angiomatoid FH and plexiform fibrohistiocytic tumors, both of which are less aggressive. Wide local excision is the treatment of choice, regardless of the histology or grade of the tumor. Patients with metastatic or unresectable MFH appear to have a poor outcome and would benefit from more effective therapies. 相似文献

PURPOSE: To evaluate response rate, event-free survival (EFS), and toxicity of two chemotherapeutic regimens for treatment of children younger than 36 months with malignant brain tumors and to estimate control intervals without irradiation in children with no residual tumor after initial surgery and induction chemotherapy and with delayed irradiation in patients with residual tumor or metastatic disease at diagnosis. PATIENTS AND METHODS: Patients were randomly assigned to one of two regimens of induction chemotherapy (vincristine, cisplatin, cyclophosphamide, and etoposide v vincristine, carboplatin, ifosfamide, and etoposide). Maintenance chemotherapy began after induction in children without progressive disease. Children with no residual tumors after induction therapy and no metastatic disease at diagnosis were not to receive radiation therapy unless their tumors progressed. RESULTS: Two hundred ninety-nine infants were enrolled. Forty-two percent of patients responded to induction chemotherapy. At 5 years from study entry, the EFS rate was 27% +/- 3%, and the survival rate was 43% +/- 3%. There was no significant difference between the two arms in terms of response rate or EFS. For medulloblastoma, supratentorial primitive neuroectodermal tumor, ependymoma, and rhabdoid tumors, 5-year EFS rates were 32% +/- 5%, 17% +/- 6%, and 32% +/- 6%, and 14% +/- 7%, respectively. Fifty-eight percent of patients who were alive 5 years after study entry had not received radiation therapy. CONCLUSION: Intensified induction chemotherapy resulted in a high response rate of malignant brain tumors in infants. Survival was comparable to that of previous studies, and most patients who survived did not receive radiation therapy. 相似文献

Ewing sarcoma is the second most frequent primary bone cancer affecting children or young adults. Advances in molecular biology have revealed common chromosomal translocations such as EWS-FLI 1 among Ewing sarcoma and related diseases such as primitive neuroectodermal tumor (PNET), so these are considered as Ewing sarcoma family tumor (ESFT). Although fewer than 10% of patients with ESFT survived before establishment of modern multiagent chemotherapy, the multimodal therapeutic regimens including combination chemotherapy, radiotherapy, and surgery can cure 60% of patients with localized disease, due to the collaborative research in European-American or the international trials. The standard chemotherapy for localized ESFT now comprises vincristine, actinomycin D, cyclophosphamide and doxorubicin (VACD) in Europe or vincristine, doxorubicin, cyclophosphamide, ifosfamide and etoposide (VDC-IE) in North America. Meanwhile, those with metastatic disease have a much worse outcome with an approximately 10-30% 5-year event-free survival rate. New American-European collaborative trials such as EURO-E.W.I.N.G.99 are in progress for further improvement of the cure rate in localized and metastatic ESFT. In Japan, Japan Ewing Sarcoma Study Group (JESS) phase II clinical trial for localized ESFT, and some clinical trials including new drugs are ongoing and waiting for results. 相似文献

BACKGROUND:
The value of local treatment in patients with primary, disseminated, multifocal Ewing sarcoma (PDMES) was investigated.METHODS:
We analyzed 120 patients registered into the European Ewing Tumor Working Initiative of National Groups (EURO‐E.W.I.N.G. 99) trial at the trial center of Muenster from 1998 to 2006. Median age was 16.2 years. Local treatment of the primary tumor was surgery in 26 of 120 patients, surgery and radiotherapy in 21 patients, and definitive radiotherapy in 40 patients. For treatment of metastases, 6 of 120 patients received surgery; 9 patients, surgery and radiotherapy; and 33 patients, definitive radiotherapy. Forty‐seven (39%) patients had local treatment of both the primary tumor and metastases, 41 (34%) patients of either the primary tumor or metastases, and 32 (27%) received no local therapy.RESULTS:
Event‐free survival (EFS) at 3 years was 0.24 (95% CI, 0.16‐0.33). Univariate analyses demonstrated the impact of local therapy given to the primary tumor: 3‐year EFS was 0.25 with surgery, 0.47 with surgery and radiotherapy, 0.23 with radiotherapy, and 0.13 when no local therapy was administered (P < .001). Three‐year EFS in PDMES was also influenced by the local treatment: surgery, 0.33; surgery and radiotherapy, 0.56; radiotherapy, 0.35; no local therapy, 0.16 (P = .003). Three‐year EFS was 0.39 in patients who received local treatment of both primary tumor and PDMES, compared with 0.17 in patients with any local treatment of either primary tumor or PDMES and 0.14 in patients with no local therapy (P < .001). Multivariate analysis showed absence of local treatment to be the major risk factor (HR = 2.21; P = .027; n = 20).CONCLUSIONS:
Local therapy of involved sites is important for patients with PDMES and should complement systemic treatment whenever possible. Cancer 2010. © 2010 American Cancer Society. 相似文献20.
BACKGROUND AND OBJECTIVES: Modern series of adult extremity soft tissue sarcomas utilize combinations of modalities in all patients. Remaining questions: 1) is it necessary to strive for wide margins in the multimodality era; 2) to use adjuvant therapy in every high-grade sarcoma? 3) Does previous partial or marginal resection seriously interfere with the definitive resection? METHODS: In a retrospective review of 194 extremity soft tissue sarcomas (1977-1994), limb preservation was possible in 181/194 (93%) of cases. Patients with narrow margins received adjuvant radiation. Some patients were referred after partial (n = 39) or "complete" (n = 63) excision. RESULTS: Local recurrence was observed in 181/141 (13%) of patients treated with wide or compartmental resection, and in 10 of 42 (24%) of those treated with conservative resection plus radiation (P = 0.14). The 5-year survival rate for grade III, >/=5-cm sarcomas was not significantly different (P = 0.82) with adjuvant (46%) or without (48%) adjuvant systemic chemotherapy. Five-year survival varied (P = 0.0001) according to grade. Patients referred with partial, or "complete" (63%, 38/63, had residual tumor at reoperation) excision had a local recurrence rate of 8% and 6%, and 5-year survival rates of 75% and 84%, respectively. CONCLUSIONS: 1) It is important to strive for wide margins even when adjuvant radiation is intended. 2) When a wide margin is possible, adjuvant radiation may not be necessary. 3) Adjuvant systemic chemotherapy may be considered for high-grade tumors, preferably within a prospective protocol. 4) A partial or "complete" excision of the tumor before referral to a tertiary center does not appear to compromise the limb preservation, local control, or survival rates of these patients. 相似文献
