AIMS: To evaluate the result of treatment and long-term outcome of a population-based cohort of patients with retroperitoneal soft tissue sarcoma (RSTS). METHODS: Between 1 January 1989 and 1 January 1994, 143 patients diagnosed as having primary RSTS were selected from a national pathology database (PALGA) in the Netherlands. In this population-based group of patients, the result of surgery, overall survival (OS) and disease-free survival (DFS) were analysed as well as factors affecting OS and DFS. Median follow-up was 10.2 years. RESULTS: Operative treatment resulted in a complete tumour resection in 55% of the patients (n=78), low- and intermediate-grade tumours were more often completely resected than high-grade tumours (P=0.016). Five- and 10-year cumulative OS was 39% and 21%, respectively, while DFS was 22% and 17%, respectively. In a multivariate analysis low malignancy grade (P=0.017) and a complete tumour resection (P<0.001) were associated with better OS. CONCLUSIONS: Complete tumour resection and low malignancy grade were independent favourable prognosticators. However, these factors were related too, since surgical success was influenced by malignancy grade. 相似文献

IntroductionLocal recurrences (LR) and distant metastases (DM) are common in retroperitoneal soft tissue sarcoma (RPS). Longer time to recurrence and resection of the recurrent lesion have been identified as beneficial prognostic factors for overall survival (OS) upon first tumor relapse. However, prognostic factors concerning OS upon subsequent recurrences are scarcely defined. In this study, we aimed to identify prognostic factors for post-relapse outcome in multiple recurrent RPS.MethodsPatients undergoing resection of primary and recurrent RPS at the University Hospital Heidelberg were retrospectively analyzed. Multivariable Cox regression analyses were performed to identify predictors of overall, LR- and DM-free survival. Subgroup analyses were performed for liposarcoma and leiomyosarcoma patients.Results201 patients with primary disease, 101 patients with first, 66 patients with second and 43 patients with third LR as well as 75 patients with DM were analyzed. More than 12 months to recurrence and resection of recurrence were associated with improved OS after resection of first and second LR (5-year OS for first/second LR; resection: 64%/62%, no resection: 20%/46%). Gross macroscopic incomplete resection of first (p < 0.001), second (p = 0.001), and third recurrences (p < 0.001) was an independent prognostic factor for poor OS.ConclusionDevelopment of LR and DM is frequent in RPS. Once a tumor relapsed, patients benefit from tumor resection not only in case of first, but also in case of subsequent recurrences. 相似文献

METHODS AND MATERIALS: Forty-five patients were consecutively treated for primary retroperitoneal soft tissue sarcoma with surgery in combination with radiation therapy in the same institution. The median follow-up time was 53 months (7-108). RESULTS: Seventeen (38%) patients had clear microscopic margins (R0 resection), 26 patients (58%) had gross complete surgical excision (R1 resection) and two patients (4%) had a macroscopic residual disease (R2 resection). External radiotherapy doses ranged from 40.8 to 59.4 Gy (mean and median: 49 Gy). Seventeen patients underwent intraoperative radiation therapy (IORT). Moreover, 11 patients received chemotherapy. The overall 1-, 2-, and 5-year survival for all 45 patients were 93, 85 and 60%, respectively. The 1-, 2-, and 5-year locoregional relapse-free rate for the whole group was 91, 70 and 40%, respectively. In univariate analysis, quality of surgery was the only variable to show a significant effect for overall survival (P=0.0386) and for local control (P=0.0059). Tumor size and tumor grade had no statistically significant effect. For the patients receiving IORT+external beam radiation therapy, no difference was observed for survival or locoregional control. The most frequent acute side effects treatment complications were radiation-induced nausea or vomiting (42%) and moderate enteritis (30%). Significant late morbidity was observed for two patients. CONCLUSIONS: This study confirms the feasibility of external postoperative radiotherapy with an acceptable level of toxicity. However, the high rate of local relapses (especially in field of radiation) does not demonstrate the usefulness of radiotherapy at the level of dose used and further preferably randomized studies should be planned. 相似文献

BACKGROUND: The purpose of this study was to retrospectively analyze the relationship between neo-adjuvant chemotherapy (NAC) and outcome in patients with high-grade extremity sarcomas. PATIENTS AND METHODS: Inclusion criteria were high-grade, deep, >5 cm extremity soft tissue sarcomas. Patients diagnosed between 1990 and 2001 were treated with surgery only (n=282) or NAC containing doxorubicin/ifosfamide/mesna (AIM) (n=74). The stratified Cox proportional hazards model was used to test the effect of NAC on disease-specific survival and recurrence while adjusting for known prognostic factors. RESULTS: NAC was associated with improved disease-specific survival for this cohort of patients (P=0.02). This overall improvement appears to be driven by the benefit of NAC on disease-specific survival for patient with tumors >10 cm. The 3-year disease-specific survival for tumors >10 cm was 0.62 (95% CI: 0.53-0.71) for patients not receiving NAC and 0.83 (95% CI: 0.72-0.95) for patients receiving NAC. CONCLUSION: NAC with AIM was associated with a significant improvement in disease-specific survival in patients with high-grade extremity soft tissue sarcomas >10 cm. These data emphasize the need for further prospective clinical studies of neo-adjuvant or adjuvant chemotherapy for patients with large high-grade extremity sarcomas. 相似文献

Retroperitoneal soft tissue sarcoma 总被引:14,自引:0,他引:14
The objective of the current study was to define the optimal treatment for patients with retroperitoneal soft tissue sarcomas (RPS). The authors conducted a review of the pertinent literature and found that the majority of patients had locally advanced RPS at the time of diagnosis. Surgery was the mainstay of treatment, and macroscopic total excision was feasible in approximately 50-67% of patients. The 5-year probability of local control was approximately 50%, and the likelihood of developing distant metastasis was approximately 20-30%. The 5-year survival rate was approximately 50%, and deaths due to recurrent RPS continued to occur after 5 years. Postoperative radiotherapy (RT) decreased the likelihood of local recurrence, although it demonstrated no impact on survival. Adjuvant chemotherapy had no proven efficacy. The factor that was found to have the greatest impact on the prognosis for patients with RPS was the ability to achieve a macroscopic total resection. The authors concluded that RPS usually is advanced at the time of diagnosis. The optimal treatment was complete resection. Most patients experienced recurrent disease after surgery, and the most common site of failure was local. Adjuvant RT reduced the risk of local recurrence, but its impact on survival was questionable. 相似文献

BACKGROUND:
This study was conducted to develop a histology‐specific nomogram to predict postoperative overall survival (OS) at 5 and 10 years in primary retroperitoneal soft tissue sarcoma (STS).METHODS:
Data registered at a single institution (National Cancer Institute, Milan, Italy) prospective sarcoma database were used. In the present analysis, patients with primary localized retroperitoneal STS resected with curative intent between 1985 and 2007 were included. A parametric piecewise exponential survival multivariate model was used for nomogram development, and internal validation was performed with standard methodologies. Known prognostic variables, such as age, tumor burden, histologic variant (as reviewed by a sarcoma pathologist), grade, and surgical margins were considered as putative predictors.RESULTS:
Among the 192 patients analyzed, within 10 years from surgery, 114 patients were alive, with a median follow‐up time of 55 months (interquartile range, 25‐104 months). Among the investigated factors, only histologic subtype did not reach significance at the 10% level. The relative hazard increased while increasing tumor size up to about 25 cm, and decreased thereafter.CONCLUSIONS:
A histology‐specific nomogram for retroperitoneal STS is now available. It can be used for better assessing the risk of the single patient and then making individualized decisions within the specific subset of retroperitoneal sarcomas. Cross‐check external validation should be performed. Cancer 2010. © 2010 American Cancer Society. 相似文献12.

Tolerance of tissue transfers to adjuvant radiation therapy in primary soft tissue sarcoma of the extremity 总被引:2,自引:0,他引:2
Spierer MM Alektiar KM Zelefsky MJ Brennan MF Cordiero PG 《International journal of radiation oncology, biology, physics》2003,56(4):1112-1116
PURPOSE: Treatment of extremity sarcomas occasionally requires tissue transfer in the form of pedicle flaps, free flaps, or skin grafts to repair surgical defects. These tissues are often subject to radiation (RT) and are therefore at risk for wound breakdown requiring reoperation. This study reviews a single center's experience with tissue transfer and postoperative RT. METODS AND MATERIALS: Between 1983 and 2000, 43 adult patients (>16 years old) with primary high-grade soft tissue extremity sarcomas underwent limb-sparing surgery and reconstruction of their surgical defects, followed by adjuvant RT. The reconstructions were as follows: pedicle flaps (n = 14), free flaps (n = 10), skin grafts (n = 4), or a combination (n = 15). Postoperative external beam radiation therapy (EBRT) (median dose: 63 Gy) alone was given to 27 patients (63%). Adjuvant brachytherapy (BRT) was given to 16 patients (37%); BRT alone (median dose: 45 Gy) was given to 12 patients and combined with EBRT for 4 patients (EBRT: 45 Gy; BRT: 20 Gy). Comorbid conditions such as diabetes, hypertension, tobacco use, and obesity (calculated using body mass index >or=30) were present in 30 patients (70%). Tumor characteristics were as follows: 26 were >5 cm in size, 37 were deep, and 30 were in the lower extremity. The median follow-up time, calculated from the date of operation, was 32 months.Five of 43 patients suffered wound complications necessitating reoperation; however, 3 patients developed complications before initiation of RT and were therefore excluded from the analysis. Two of 43 patients (5%) required reoperation for wound complications after RT; 1 of these patients ultimately required amputation for necrosis. The 5-year overall wound reoperation rate was 6% (95% confidence interval: 0-14%). The influence of patient and tumor characteristics, as well as the type of RT, on the wound reoperation rates is as follows: BRT vs. EBRT (17% vs. 0%, p = 0.06); upper vs. lower extremity (0% vs. 8%, p = 0.41); 5 cm (8% vs. 4%, p = 0.9); comorbidity vs. no comorbidity (3% vs. 13%, p = 0.8); age 50 (8% vs. 4%, p = 0.8). CONCLUSION: Based on this review, most tissue transfers (95%) tolerated subsequent adjuvant radiation therapy well. Although more wound complications necessitating reoperation were seen in patients who received BRT, whether this is because of the inherent susceptibility of flaps and skin grafts to breakdown in the immediate postoperative period vs. the direct result of BRT needs further investigation. 相似文献

Patients with high-risk soft tissue sarcomas (STS)–FNCLCC grade 2–3, size >5 cm, deep to the fascia—are at risk for developing
local recurrence and distant metastasis despite surgical tumor resection. Therefore, the management of high–risk STS requires
a multidisciplinary approach. Besides surgery, radiotherapy, and chemotherapy, regional hyperthermia (RHT) has the potential
to become the fourth standard treatment modality for the treatment of these patients. RHT means non-invasive selective heating
of the tumor area to temperatures within the range of 40–43°C for 60 min by the use of an electromagnetic heating device.
Thereby RHT is always applied in addition to radiotherapy or chemotherapy or both but is not effective as a single treatment.
Beside direct cytotoxicity, RHT in combination with chemotherapy enhances the drug cytotoxicity mainly by increased chemical
reaction and intratumoral drug accumulation. For the neoadjuvant setting, RHT in combination with a doxorubicin- and ifosfamide-based
chemotherapy has been shown to dramatically improve the tumor response rate but also prevents from early disease progression
as compared to chemotherapy alone. The addition of RHT to a multimodal treatment of high-risk STS consisting of surgery, radiotherapy,
and chemotherapy either in the neoadjuvant setting but also after incomplete or marginal tumor resection has been shown to
significantly improve local recurrence- and disease-free survival. Based on these results and in conjunction with the low
RHT-related toxicity, RHT combined with preoperative or postoperative chemotherapy should be considered as an additional standard
treatment option for the multidisciplinary treatment of locally advanced high-grade STS. 相似文献

Opinion statement Primary soft tissue sarcoma (STS) of the breast is a rare and heterogeneous disease. The rarity of this tumor limits most
studies to small retrospective case reviews and case reports. The optimal treatment of primary STS of the breast can best
be determined through multidisciplinary discussions prior to the initiation of therapy. Whether chemotherapy is indicated
is primarily determined by tumor size. There is evidence that tumors larger than 5 cm are associated with an elevated risk
of systemic failure and a poor prognosis [1-3]. Negative surgical margins are more important for local recurrence and overall
survival than is the extent of surgical resection [1]. Thus, neoadjuvant chemotherapy should be considered in order to shrink
the tumor and help obtain negative surgical margins. After surgical resection, patients with chemosensitive tumors should
undergo additional adjuvant chemotherapy to treat micrometastatic disease. Patients with tumors less than 5 cm that are easily
resectable should undergo complete resection to the extent required to provide negative surgical margins. Radiation therapy
should be used to improve local control in cases in which the tumor is larger than 5 cm and in cases with positive surgical
margins [4-6]. The appropriate treatment of primary STS of the breast requires a multidisciplinary approach necessitating
experienced surgeons, pathologists, radiotherapists, and medical oncologists. 相似文献

Soft tissue sarcomas (STS) are a rare and diverse group of tumors that affect both adult and pediatric populations. This review discusses current screening recommendations for populations at increased risk for STS, including those with genetic predispositions. We also review surveillance guidelines for those at risk for recurrence following curative-intent surgery. 相似文献
