The natural history of great toe amputations

The purpose of this study is to report the prevalence of reamputation following resection of the great toe and first ray in adults with diabetes. We abstracted the medical records of 90 diabetic great-toe and first-ray amputees admitted between 1981 and 1991. The most common etiologies of initial amputations were ulcer with soft tissue infection (39%), ulcer with osteomyelitis (32%), and puncture wounds (12%). Sixty percent of all patients had a second amputation, 21% had a third, and 7% had a fourth. Fifteen percent of the patients who had a second amputation had it contralaterally. Seventeen percent subsequently underwent a below-knee amputation and 11% had a Transmetatarsal amputation on the same extremity, 3% had a below-knee amputation, and 2% a transmetatarsal amputation contralaterally. The mean time from the first to the second amputation was approximately 10 months. The results of this study suggest that a large proportion of patients undergoing an amputation at the level of the great toe or first ray have subsequent amputations in the first year following the initial procedure. Additionally, it appears that the contralateral foot may be at significant risk for distal amputation following resection of the hallux or first day.     

Resectability of retroperitoneal sarcomas: a matter of surgical technique?

The management of retroperitoneal sarcomas has been hampered by the difficulty in complete resection, the resectability rate in the literature being about 53%. In a review of the last 88 consecutive patients with retroperitoneal sarcomas the resectability rate was 95%. At a mean follow-up of 48 months, the local recurrence rate was 17% following wide resection and 59% following local excision (P = 0.0002). For patients with minimum follow-up of 5 years, the local recurrence rate was 39% for those with primary tumours and 57% for those referred with local recurrence. Local recurrence diminished the rate of long-term survival. The 5- and 10-year survival rates for the primary retroperitoneal sarcomas (n = 55) were 66% and 57% and for those referred with locally recurrent sarcoma (n = 33) 57% and 26%, respectively. The 5-year survival rate varied significantly with the grade of the tumour, from 88% for Grade I to 44% for Grade III tumours (P = 0.006). In conclusion, with modern surgical techniques the resectability rate of retroperitoneal sarcomas is about 95%, and the survival rate of the primary tumours approximates that of the primary soft tissue sarcomas of the extremities.     

Soft tissue sarcomas

Soft tissue sarcomas are relatively rare tumors with an annual incidence of 5000 to 6000 in the United States. The primary therapy is surgical resection with an adequate margin of normal tissue. For patients at high risk local control is improved with postoperative adjuvant radiation. Local recurrence rates vary depending on the anatomic site. In extremity lesions one third of patients will have locally recurrent disease with a median disease-free interval of 18 months. Treatment results for extremity local recurrence may approach those for primary disease. Isolated pulmonary metastases may be resected with 20% to 30% 3-year survival rates. Patients with sarcomas in other sites present similar but more difficult problems in terms of local control and management of disseminated disease. Patients with unresectable pulmonary metastases or extrapulmonary metastatic sarcoma have a uniformly poor prognosis and are best treated with systemic chemotherapy.     

Surgical aspects in the multidisciplinary treatment of soft tissue sarcomas

Sarcomas are rare malignant tumors with a large variety of histologic subtypes. The surgical approach depends more on the histologic grade, the size and the site of the tumor. Radiologic diagnosis relies predominantly on MR-imaging. Discernible improvements have taken place in soft tissue sarcoma patient survivorship and quality of life over the past 20 years, with overall 5-year survival currently at approximately 50-80%. The place of surgery in the treatment of soft-tissue sarcoma is defined in the light of a review of the recent literature. Radical surgical resection is the mainstay of therapy. Local recurrence is the most common type of failure. Local recurrence is resectable and limb preservations possible in the majority of patients. Survival after treatment of local recurrence is determined mainly by the grade and secondarily by the size of the tumor. The essential risk factor for local recurrence is the quality of surgical resection, defined by the definitive resection margins. A lateral safety margin of 5 cm and of 2 cm to the depth should be respected. In sarcoma of the extremity the compartment is defined based on clinical, radiographic, histopathologic and operative findings. The use of muscle flaps to fill the surgical defects can improve the functional result and reduce the complication rate. Only about 5% of the patients need amputation. Evaluation of functional results must be based on objective criteria. In retroperitoneal sarcoma the significant factors for determining prognosis are grade and completeness of exzision. Multidisciplinary treatment according to common protocols is essential. Shifts in treatment have taken place over the past decade, from single-modality treatment involving radical surgery with compartment resection to sophisticated limb-salvage strategies combined with radiation therapy. In case of inadequate surgery e.g. in a large tumor with positive margins in high-grade soft tissue sarcomas the addition of radiotherapy can improve local control, but cannot ensure that obtained by adequate surgery. Patients with large (greater than 5 cm), high grade soft tissue sarcoma are at high risk for distant recurrence and disease-related mortality. Investigations of combined modality therapy with newer chemotherapy agents and dose intensification treatment strategies are warranted.     

Childhood soft tissue sarcoma: a 20-year experience

PURPOSE: To evaluate the disease-free and overall survival of pediatric patients with nonrhabdomyosarcoma soft-tissue sarcomas. METHODS: We retrospectively analyzed the records of 67 pediatric patients with a diagnosis of nonrhabdomyosarcoma soft tissue sarcoma treated with curative intent between 1970 and 1992. Median follow-up time for the 52 survivors was 120 months (range, 7 to 277 months). Fifty-nine patients received external beam radiotherapy, in a median dose of 5400 cGy (range, 1800 to 6660 cGy.) All patients underwent an initial surgical procedure. Eighteen patients had gross residual disease, and 15 had gross total excision with microscopic residual disease or positive margins. Adjuvant chemotherapy was administered to 44 patients (65%). RESULTS: The actuarial 10-year freedom from progression or recurrence and overall survival rates were 76% and 75%, and the 20-year rates were the same. Of 18 patients with gross residual disease, 9 (50%) had local progression and 6 died of local-only disease. By contrast, only one patient with microscopic residual disease who received postoperative radiotherapy had a local recurrence. The disease-free survival rate also correlated with histologic grade. CONCLUSIONS: As with adult soft tissue sarcomas, gross residual disease predicts local failure. Our results suggest that pediatric patients with soft tissue sarcomas treated with surgery and postoperative radiotherapy generally have a favorable overall survival rate.     

Preoperative radiation, surgical margins, and local control of extremity sarcomas of soft tissues

The relationship between status of the surgical margin and local control of soft tissue sarcoma of the extremities by preoperative radiation therapy has been assessed in 132 consecutive patients from 1974 to 1988. The 5-year actuarial local control rate was 94% for all patients; the rates were 97% and 82% for the 104 tumors with negative margins and the 28 tumors with positive margins, respectively. The local control rate was independent of the extent of the negative margin. For primary sarcomas, the local control rates were 96%, 97%, and 100%, respectively, for margins that were negative at < or = 1 mm or > 1 mm, or the specimens were negative for tumor; for positive margins the result was 83%. The overall local control rate was lower (not significant) for recurrent than for primary sarcomas: 88% vs. 94%. On the other hand, when stratifying by margin status, no difference was observed in local control results, i.e.: (1) 97% and 91% for primary and recurrent tumors with negative margins, respectively, and (2) 83% and 80% for primary and recurrent tumors with positive margins, respectively. Local control was not significantly higher in those patients who were treated by surgical resection (S), radiation (RT), and re-excision of the previous tumor bed than in those whose radiation therapy was started after the biopsy and followed by one surgical resection. For primary sarcomas that were resected with negative margins the results were: 100% of 15 patients treated by S-RT-S and 96% of 75 patients treated by RT-S.     

Limb salvage surgery for widely infiltrating bony sarcomas

OBJECTIVE: To determine whether neoadjuvant chemotherapy and radiotherapy for bony sarcomas extending into soft tissues would allow limb salvage yet maintain local disease control. DESIGN: A prospective cohort study. SETTING: A university-affiliated cancer centre in Alberta. PATIENTS: All patients with potentially curable, widely infiltrating bony sarcomas of the extremity without neurologic deficit, referred to the centre in the 6 years from January 1984 to December 1990. There were 11 patients; 1 did not complete the protocol. The mean follow-up was 24 months. INTERVENTIONS: Adriamycin (doxorubicin) was infused for 3 days at a rate of 30 mg/d. A few days later radiotherapy was given 5 days a week for 10 doses at a rate of 3.0 Gy per dose. Four to 5 weeks later the tumour was excised surgically, with placement of a bone allograft or prosthesis, allowing a 1-cm margin of healthy soft tissue and a 5-cm margin of healthy bone and marrow cavity whenever possible. MAIN OUTCOME MEASURES: Need for limb amputation, infectious complications, recurrence of local or regional disease. RESULTS: One patient underwent amputation after fracture through the tumour site. There were two postoperative infections, one acute and one chronic. All patients had full neurologic function of the distal limb. There was no local or regional recurrence of disease. CONCLUSION: Neoadjuvant chemotherapy followed by radiotherapy and tumour excision provides control of aggressive local bone sarcomas while maintaining limb integrity.     

Metastatic carcinoma to skeletal muscle. A report of 15 patients

The records of 15 patients with metastatic carcinoma to skeletal muscle treated between 1979 and the present were reviewed. Fourteen patients were referred with a diagnosis of soft tissue sarcoma and one with suspected infection. There was a previous diagnosis of carcinoma in eight patients but seven patients had no prior diagnosis of a known malignancy. Primary tumors were lung (eight), melanoma (two), gastrointestinal (one), kidney (one), and bladder (one). No primary tumor could be identified in two patients. Local control of metastatic lesions was achieved by radiotherapy in 11 patients as an initial measure. Two patients underwent wide excision and one declined treatment for local tumor control. Eight patients died within 12 months of presentation and survival analysis indicated a 25% overall survival at 60 months. Two patients remained free of disease at 132 months and 72 months. From this study and a review of 52 cases reported in the literature, the authors are unable to find any clinical or radiographic characteristics that distinguish metastatic carcinoma to muscle from soft tissue sarcomas. Surgical resection can be reserved for cases in which radiation does not provide local control.     

Relationship between CA 15-3 serum levels and disease extent in predicting overall survival of breast cancer patients with newly diagnosed metastatic disease

Soft tissue sarcomas (STS) of the hand are rare in children and adolescents. From 1965 through 1995, 18 children with STS of the hand were treated at our institution. Rhabdomyosarcoma (RMS) was diagnosed in 11 patients; alveolar histological results predominated (7 of 11 cases). Seven patients presented with metastatic disease and died 4 to 23 months (median, 9 months) from diagnosis; their surgical treatment comprised above-elbow amputation (n = 1), local excision (n = 1), and biopsy (n = 5). For the four patients who presented with localized RMS, surgery consisted of wide local excision (n = 1), local excision (n = 2), or ray amputation (n = 1). With an average follow-up of 5.5 years (range, 4 months to 18 years), 3 of the 11 patients diagnosed with RMS still survive (27%). The remaining seven patients presented with nonrhabdomyosarcomatous soft tissue sarcoma (NRSTS); the most common histological variants were epithelioid and malignant fibrous histiocytoma (two cases each). Surgical treatment for these patients comprised ray amputation (n = 3), wide local excision (n = 3), excisional biopsy (n = 1), and regional lymph node dissection (n = 3). One patient received adjuvant multiagent chemotherapy; three patients received supplemental radiotherapy. Six of the seven (85%) patients are alive with no evidence of disease at an average follow-up of 4.7 years (range, 6 months to 12 years).     

Sensitization of olfactory guanylyl cyclase to a specific imprinted odorant in coho salmon

PURPOSE: Local recurrence is a significant problem following primary surgery for advanced vulva carcinoma. The objectives of this study were to evaluate the impact of adjuvant vulvar radiation on local control in high risk patients and the impact of local recurrence on overall survival. METHODS AND MATERIALS: From 1980-1994, 62 patients with invasive vulva carcinoma and either positive or close (less 8 mm) margins of excision were retrospectively studied. Thirty-one patients were treated with adjuvant radiation therapy to the vulva and 31 patients were observed after surgery. Kaplan-Meier estimates and the Cox proportional hazard regression model were used to evaluate the effect of adjuvant radiation therapy on local recurrence and overall survival. Independent prognostic factors for local recurrence and survival were also assessed. RESULTS: Local recurrence occurred in 58% of observed patients and 16% in patients treated with adjuvant radiation therapy. Adjuvant radiation therapy significantly reduced local recurrence rates in both the close margin and positive margin groups (p = 0.036, p = 0.0048). On both univariate and multivariate analysis adjuvant radiation and margins of excision were significant prognostic predictors for local control. Significant determinants of actuarial survival included International Federation of Gynecologists and Obstetricians (FIGO) stage, percentage of pathologically positive inguinal nodes and margins of excision. The positive margin observed group had a significantly poorer actuarial 5 year survival than the other groups (p = 0.0016) and adjuvant radiation significantly improved survival for this group. The 2 year actuarial survival after developing local recurrence was 25%. Local recurrence was a significant predictor for death from vulva carcinoma (risk ratio 3.54). CONCLUSION: Local recurrence is a common occurrence in high risk patients. In this study adjuvant radiation therapy significantly reduced local recurrence rates and may improve overall survival in certain subgroups. As salvage rates after developing local recurrence are poor adjuvant vulvar radiation should be considered for patients at risk after primary surgery.     

Pharmacokinetics of tacrolimus (FK506) in primary orthotopic heart transplant patients

STUDY OBJECTIVES: Local recurrence is high when sublobar resection is chosen as primary management of stage I non-small cell lung carcinoma. Postoperative external-beam radiotherapy may reduce this local recurrence problem. A technique of intraoperative brachyradiotherapy following thoracoscopic wedge resection is described as an alternative to adjuvant external-beam radiotherapy for high-risk patients who are not candidates for pulmonary lobectomy. PATIENTS: Fourteen patients with significant impairment in cardiopulmonary function having small peripheral solitary pulmonary nodules underwent video-assisted thoracoscopic (VATS) wedge resection and were found to have non-small cell cancer. Surgical margins were pathologically clear and mediastinal nodes were benign-stage I (T1NO). INTERVENTIONS: A custom polyglyconate mesh (Vicryl) containing 125I seeds was applied to pulmonary resection margins following wedge resection of peripheral lung cancers. A total dose of 100 to 120 Gy at 1 cm was applied to the target area. RESULTS: All patients had histologically clear surgical margins. Postoperative dosimetry confirmed adequate resection margin coverage. There was neither operative mortality nor morbidity related to the VATS wedge resection or the brachytherapy implants. Implants did not migrate, and there were no cases of significant radiation pneumonitis or local recurrence at mean follow-up of 7 months (range, 2 to 12 months). CONCLUSIONS: Intraoperative brachytherapy appears to be a safe and efficient alternative to external-beam radiation therapy when adjuvant radiotherapy is considered following therapeutic wedge resection of stage I (T1NO) lung cancers. The impact on local recurrence, disease-free interval, and survival will require additional follow-up.     

The role of surgical therapy in patients with nonmetastatic Ewing's sarcoma of the limbs

Of 131 patients with primary Ewing's sarcoma (ES) with extremity locations, treated between April 1972 and May 1987, 13 had amputation; 56 had a local resection with 31 (55%) requiring radiation therapy (RT) as an adjuvant to local therapy. Sixty-two of 131 patients (47%) had RT only. Local recurrences were reported in 5% of patients treated with surgery alone, 1% of the group treated with surgery and radiation therapy, 24% of patients treated with radiation therapy alone (46% for cesium-radiation therapy, and 12% with cobalt-radiation therapy).     

Cisplatin-based neoadjuvant chemotherapy and combined resection for ethmoid sinus adenocarcinoma reaching and/or invading the skull base

OBJECTIVE: To review our experience with cisplatin-based neoadjuvant chemotherapy before en bloc resection via a combined neurosurgical and transfacial approach for ethmoid sinus adenocarcinoma reaching and/or invading the skull base. DESIGN: Case series. SETTING: A tertiary care center and university teaching hospital. PATIENTS: Twenty-two patients with primary untreated ethmoid sinus adenocarcinoma reaching and/or invading the skull base consecutively treated between 1984 and 1992 with cisplatin-based neoadjuvant chemotherapy and combined neurosurgical and transfacial approach. MAIN OUTCOME MEASURES: Statistical analysis of survival, local control, nodal recurrence, distant metastasis, and metachronous second primary tumor incidence based on the Kaplan-Meier actuarial method. Univariate analysis was performed to analyze the relationships between various factors, survival, and local recurrence. Clinical response, histological response, toxic effects of chemotherapy, and postoperative course were also reported. RESULTS: The Kaplan-Meier 3-year survival, local control, nodal recurrence, and distant metastasis estimates were 68.1%, 65.7%, 5.3%, and 10%, respectively. Metachronous second primary tumor was not encountered in our series. Survival was statistically more likely to be reduced in patients with intrasphenoidal tumor extent (P = .04) and local recurrence (P = .01). Local recurrence was statistically more likely in patients with intrasphenoidal tumor extent (P = .002) and no response to cisplatin-based neoadjuvant chemotherapy (P = .03). CONCLUSIONS: The results achieved suggest that cisplatin-based neoadjuvant chemotherapy before combined neurosurgical and transfacial approach should be further investigated for the treatment of ethmoid sinus adenocarcinoma reaching and/or invading the skull base.     

Myofibrosarcoma of the head and neck in children

We have identified a distinctive malignant soft tissue neoplasm that occurred in the head and neck region of six children. Histologically, these neoplasms presented an array of features ranging from low-grade spindle cell to high-grade fibrohistiocytic histologies and often had myoid characteristics. Ultrastructural and immunohistochemical studies indicated that they contained neoplastic myofibroblasts that were variably positive for vimentin (4 positive/4 tested), alpha-smooth muscle actin (4/5), muscle-specific actin (5/5), desmin (2/5), and v-src protein substrate p80/85 (4/5). Three patients died of rapidly progressive unresectable local disease, one died of metastatic and local disease, and two are alive 13 months and 8 years after wide resection. We conclude that these neoplasms form a distinctive subset of pediatric soft tissue sarcomas that display an aggressive clinical behavior, typically with local recurrence, and exhibit features of myofibroblastic differentiation.     

Functioning muscle transplantation after wide excision of sarcomas in the extremity

Free functioning muscle transplantation was performed after resection of 23 sarcomas in the extremity. There were 21 soft tissue sarcomas and two malignant bone tumors. The tumor resection was performed with a wide margin in all except two patients who had a marginal margin in a limited area. The consequent extensive soft tissue defect received free musculocutaneous flaps, the motor nerve of which was repaired in the recipient site. The most frequent procedure was latissimus dorsi transplantation to replace thigh muscles in 17 cases. The other donors included gracilis, tensor fascia lata, and rectus femoris, which were selected according to the site of defects. Patients were followed up for a mean of 60 months (range, 13-119 months). The grafted muscles showed reinnervation at a mean of 6 months postoperatively in all patients except for a 75-year-old patient. Obtained contraction of the muscles was powerful in 18 patients and fair in four patients. Performance of the salvaged limb significantly improved after recovery of the muscles. Although there were five distant recurrences, local recurrence was seen in one patient with systemic metastases. Because muscle loss could be compensated functionally for by the innervated free muscle transfer, the method encouraged surgeons to perform more radical tumor excisions and this may have contributed to the excellent local tumor control that was achieved. Thus, functioning muscle transplantation was extremely useful in limb salvage surgery from the functional and oncologic viewpoints.     

Influence of surgery on metachronous distant metastases and survival in rectal cancer

PURPOSE: Total mesorectal excision (TME) and other technical surgical factors reduce local recurrence rate in rectal cancer. Scientific evidence of the positive effect of optimal surgery on survival is locking. Whether a reduction in the incidence of distant metastases can be achieved with optimal surgery is uncertain. We examine the effects of the quality of surgery, as reflected by local recurrence rate, on survival and the incidence of initial distant metastases. PATIENTS AND METHODS: Between 1974 and 1991, 1,581 consecutive patients who underwent curative resection (RO) for rectal carcinoma were monitored for recurrence and survival. TME was introduced in 1985. No patient received adjuvant radiotherapy or chemotherapy. The median follow-up time was greater than 13 years. RESULTS: The local recurrence rate decreased from 39.4% to 9.8% during the study period (P < .0001). The observed 5-year survival rate improved from 50% to 71% (P < .0001). Three hundred six patients with local recurrence had a significantly lower observed 5-year survival rate (P < .0001). A total of 1,285 patients had no local recurrence, but 275 of them developed distant metastases (International Union Against Cancer [UICC] stage I, 8%; stage II, 16%; stage III, 40%). Better-quality surgery had no effect on the incidence of initial distant metastases, which remained constant (P = .44). CONCLUSION: Quality of surgery is an independent prognostic factor for survival in rectal cancer, but has no influence on initial occurrence of distant metastases. Local recurrence cannot be considered an outcome criterion of adjuvant treatment without consideration of the surgeon as a risk factor.     

Recovered memory therapy: a dubious practice technique

BACKGROUND: Adjuvant chemotherapy and endoprosthetic replacement for bone sarcomas of the lower extremity is well established. The specific long-term consequences of these endoprosthetic reconstructions for the patient's affected limb are unknown. METHOD: The oncologic results and the survival of the endoprostheses were reviewed in 32 patients with primary bone sarcoma of the femur or proximal tibia. There were 26 high-grade sarcomas, and 6 low-grade sarcomas. A proximal femoral endoprosthesis was used for reconstruction in 4 patients, a total or push-through femoral endoprosthesis in 11 patients, a distal femoral endoprosthesis in 15 patients, and a proximal tibial endoprosthesis in two patients. RESULTS: Median survival was 10 years (range, 1.1 to 18.9 years) for patients with high-grade sarcoma, and 8.1 years (range, 7.1 to 10 years) for patients with low-grade sarcomas. Distant metastases developed in seven patients (22%), all with stage IIB sarcoma, with concomitant local recurrence in 3 patients (9%). Five-year overall and disease-free survival rates for high-grade sarcomas were 81% and 73%, respectively. The overall endoprosthetic survival rate was 87% at 5 years, 80% at 10 years, and 56% at 15 years. Median follow-up of the original endoprostheses was 8.3 years (range, 0.6 to 18.7 years). Endoprosthesis-related complications occurred in 13 patients (41%); most complications were mechanical failures. The highest complication rate was found in distal femoral replacements (60%); amputation was necessary in both patients treated with a proximal tibial endoprosthesis. Five endoprostheses (16%) were revised. An amputation of the involved limb was performed in four patients (13%): in two patients because of local recurrence and in the other two patients because of infection. For patients alive at follow-up, the median functional Enneking evaluation score was 22 points (range, 12 to 28 points), with the highest functional scores in patients with a distal femoral endoprosthesis, and the lowest functional scores in patients with total or push-through femoral replacements. CONCLUSION: Endoprosthetic reconstructions gave satisfying functional results in most patients after long-term survival. However, the proximal tibial and distal femoral endoprosthesis are particularly at risk for long-term endoprosthetic complications requiring additional surgical procedures.     

Diabetic foot--an attempt at defining the risk factors for amputation]

The study included 65 patients--42 males and 23 females aged 67 +/- 17 with the diabetic foot syndrome. They were divided into 2 groups: those who underwent amputation (25 patients) and 40 who were treated conservatively. Amputations were preceded most frequently by ulceration (17 cases), phlegmona (5 cases) or dry necrosis (3 cases). The high percentage of amputations in the studied patients could be explained, at least in part, by poor general condition and advanced local changes. In the group of patients, who underwent amputation--in relation to those treated conservatively a decrease in filtration function was found (46.0 +/- 24.3 vs 89.5 +/- 26.2) and a higher percentage in the prevalence of microalbuminuria or proteinuria (80% vs 45%) as well as a higher percentage of cigarettes smokers in this group (72% vs 40%). The majority of the studied patients was characterized by poor education, lack of self-control of glycaemia, no efficient metabolic control of diabetes, measured by glycated haemoglobin and the presence of neuropathy and retinopathy. In addition, in 4 patients among the whole studied group (including 1 patient who underwent amputation), diabetes was newly diagnosed. These results indicate the necessity of improving education, early diagnosis of insulin independent diabetes, more frequent foot examinations and the elimination of amputation risk factors. Prophylaxis of diabetes foot associated with the proper treatment of diabetes is a necessary condition for decreasing of the amputation rate according to St. Vincent Declaration.     

Extremity soft tissue sarcoma with metastases to abdominopelvic surfaces

BACKGROUND: In a majority of patients with extremity soft tissue sarcoma, the lungs are the first site at which recurrent disease is detected. Other common sites of recurrence are the resection site, bone metastasis, and liver metastasis. Although abdomino pelvic sarcomatosis is common as a site of recurrence for visceral and retroperitoneal sarcoma, it has not been previously reported for extremity sarcoma. METHOD: We present three patients in whom extremity soft tissue sarcoma metastasized to the peritoneal surfaces, and in all three patients this was symptomatically the dominant site for recurrence. All of them underwent a palliative surgical cytoreduction and were then treated with intraperitoneal chemotherapy. RESULTS: In two of the three patients, isolated progression of peritoneal sarcomatosis has again occurred: one patient remains disease free at 14 months. CONCLUSIONS: Metastasis to peritoneal surfaces within the abdomen and pelvis must be considered a possible site for systemic dissemination of extremity soft tissue sarcomas. Effective treatments for sarcoma spread to peritoneal surfaces would benefit this small but symptomatic group of patients.
