The aims of this study were to evaluate the long-term outcome
of surgery for bone or soft-tissue metastases from renal cell carcinoma
(RCC) and to determine factors that affect prognosis. Between 1993 and 2014, 58 patients underwent surgery for bone
or soft-tissue metastases from RCC at our hospital. There were 46
men and 12 women with a mean age of 60 years (25 to 84). The mean
follow-up period was 52 months (1 to 257). The surgical sites included
the spine (33 patients), appendicular skeleton (ten patients), pelvis (eight
patients), thorax (four patients), and soft tissue (three patients).

Introduction. Surgical treatment of spinal metastasis belongs to the standards of oncology. The risk of spinal cord compression represents an operative indication. Intraoperative bleeding may vary, depending on the extent of the surgical technique. Some primary tumors, such as the
Introduction: There is increasing evidence that surgical treatment in tumour surgery can influence survival times.
There is very limited literature available on the use of prosthetic replacement in the treatment of primary and secondary tumours of the radius. In the past these were treated with vascularised and non-vascularised autografts which had associated donor site morbidity, problems of non union, graft or junctional fractures and delayed return to function. Our study is a mid to long term follow-up of implant survivorship and the functional outcome of metal prosthetic replacement used for primary and metastatic lesions of radius. We had 15 patients (8 males:7 females) with a mean age of 53 years. 8 patients underwent proximal radial replacement, 2 with mid-shaft radial replacement and 6 patients had distal radial replacements with wrist arthrodesis. The indications for replacement included metastatic lesions from
Introduction: Modern cancer treatment has substantially increased the survival of patients with various malignancies. One of the late sequelae of a successful treatment is the development of a second malignant tumor. However, in many cases of second primary cancers, exposure to chemotherapy or radiation therapy is not evident, and it should be postulated that the putative mechanism for the development of the second cancer is different. Material and Methods: Retrospective search of data files of 610 patients with soft-tissue or bone sarcomas that were treated by the authors from January 1995 through December 1999 were performed. Results: Out of 375 patients with soft-tissue sarcoma (STS), 28 (7.5%) developed other malignant neoplasm either before or after its diagnosis. The second tumor types included mainly STS and
In contrast to bony metastases, soft tissue metastases from carcinoma are rare. We reviewed all referrals to our Sarcoma Unit over an eight-year period, and found an incidence of soft tissue metastases from carcinoma of 1.4%. The most common mode of presentation was a painless soft tissue lump in a patient with an occult primary. Lung and kidney were the most frequent primary sources. Overall, prognosis was poor, with a mean survival of 9.4 months. Renal tumours however had a much better prognosis that other types of tumours. Treatment should be individualised according to the underlying disease and the prognosis. Although much rarer than primary soft tissue sarcomas, soft tissue metastases from carcinoma should remain a differential diagnosis in any patient presenting with a suspicious soft tissue lump. Introduction: Carcinoma most commonly metastasises via the lymphatic system firstly to the regional lymph nodes and then into the general circulation. Dependent upon the primary site of tumour, metastases from carcinoma commonly occur to the lungs, liver and bone. Distant metastases to the soft tissues are rare. There are few published case series (. 1. ,. 2. ) – the majority of the literature containing only case reports. We report a series of 10 cases of soft tissue metastases from carcinoma, collected from retrospective review of the case notes of consecutive patients referred over a eight year period to our Sarcoma Unit with a soft tissue lump, suspicious of a sarcoma. Patients and Methods: We retrospectively reviewed the case notes of consecutive patients over a eight year period (April 1995 – April 2003) referred to our Unit with a soft tissue lump, suspicious of a sarcoma. All patients underwent magnetic resonance (MR) scanning, and then trucut or open biopsy of the lesion. Dependent on the histological and MR findings, patients then underwent computer tomography (CT) of the chest and ultrasound examination of the abdomen. Included in this series were all patients with a histologically proven, soft tissue (skeletal muscle or subcutaneous tissue) metastatic carcinomatous deposit. Demographic, diagnostic, clinical, radiological and treatment data was collected on all patients. Results: Of the 702 referrals to our Unit over the eight-year period with a soft tissue lump suspicious of a sarcoma, 10 cases proved to be soft tissue metastases from carcinomas (incidence 1.4%). Data for the 10 patients comprising the series is shown in Table 1. Eight of the patients were male, two were female. The mean age at presentation was 68 years (range 39–85 years). Two patients presented with a painful lump, and in the other eight patients the lump was asymptomatic. The involved sites included the thigh in four cases, the arm in three cases, the back, buttock and axilla one each.In nine cases, the soft tissue lump was the presenting symptom of an occult primary carcinoma, whilst in one case (Case 4); the patient had a history of previous excision of a hypernephroma. The sources of primary carcinoma were small cell carcinoma of the lung in 4 cases,
SEREX was used to identify candidate tumor antigens in the nonimmunogenic fibrosarcoma (NFSA) tumor model. One of the six clones identified was of particular interest. NFSA-5 was identified as the receptor for hylaronan-acid-mediated motility (RHAMM), which is involved in cell growth and metastasis. RHAMM is expressed in a variety of human tumors. RHAMM is differentially expressed, with significant levels not found in normal tissues other than testis, placenta, and thymus. Therefore, RHAMM may be an appealing target for human tumor vaccines. The identification of murine homologs to human tumor antigens may aid in the preclinical development of human tumor vaccines. The goal of our studies was to use serological analysis of antigens by recombinant expression cloning (SEREX) to identify candidate tumor antigens in a nonimmunogenic murine fibrosarcoma model. SEREX provides a rapid means of identifying candidate tumor antigens in murine cancer models. The identification of murine homologs to human tumor antigens may aid in the preclinical development of human tumor vaccines. The SEREX approach included construction of a cDNA expression library from NFSA tumors followed by immunoscreening of the library with sera from C3H mice growing NFSA tumors. The nucleotide sequence of insert cDNA was determined for positive clones. Sequence alignments were performed with BLAST software on GenBank database. Six positive clones were identified. Two clones coded for proteins with known expression in normal tissues. Two clones represented heat-shock proteins, known to be upregulated in human and murine tumors. Two of the clones were of particular interest. Clone NFSA-1 was the homolog to NY-REN-58, an antigen previously identified by SEREX analysis of
National Institute of Clinical Excellence guidelines on Metastatic Spinal Cord Compression recommend urgent consideration of patients with spinal metastases and imaging evidence of structural spinal failure with spinal instability for surgery to stabilise the spine and prevent Metastatic Spinal Cord Compression. We aimed to compare neurological outcomes of patients managed operatively and non-operatively. Prospective collection of 397 patients' data over a 4-year period. Males represented 59.2% of patients. Median age was 69 years. Non-operative intervention in 62.2% of patients. Prostate, lung, Breast, Myeloma,
The rate of fracture and subsequent nonunion after radiation therapy for soft-tissue sarcomas and bone tumors has been demonstrated to quite high. There is a paucity of data describing the optimal treatment for these nonunions. Free vascularized fibular grafts (FVFG) have been used successfully in the treatment of large segmental bone defects in the axial and appendicular skeleton, however, their efficacy with respect to treatment of radiated nonunions remains unclear. The purpose of the study was to assess the 1) union rate, 2) clinical outcomes, and 3) complications following FVFG for radiation-induced femoral fracture nonunions. We identified 24 patients who underwent FVFG for the treatment of radiation-induced femoral fracture nonunion between 1991 and 2015. Medical records were reviewed in order to determine oncologic diagnosis, total preoperative radiation dose, type of surgical treatment for the nonunion, clinical outcomes, and postoperative complications. There were 11 males and 13 females, with a mean age of 59 years (range, 29 – 78) and a mean follow-up duration of 61 months (range, 10 – 183 months). Three patients had a history of diabetes mellitus and three were current tobacco users at the time of FVFG. No patient was receiving chemotherapy during recovery from FVFG. Oncologic diagnoses included unspecified soft tissue sarcomas (n = 5), undifferentiated pleomorphic sarcoma (UPS) (n = 3), myxofibrosarcoma (n = 3), liposarcoma (n = 2), Ewing's sarcoma (n = 2), lymphoma (n = 2), hemangiopericytoma, leiomyosarcoma, multiple myeloma, myxoid chondrosarcoma, myxoid liposarcoma, neurofibrosarcoma, and
Six patients underwent wide segmental resection and limb salvage surgery for primary or metastatic bone tumors involving the diaphysis of the femur, the tibia and the humerus using a modular intramedullary diaphyseal segmental defect fixation system. There were 4 men and 2 women with a mean age of 62 years (range, 40 to 77 years). Histological diagnosis included adamantinoma, dedifferentiated synovial sarcoma attached to the tibia, multiple myeloma, and metastatic
Aim. To present selective arterial embolization with N-2-butyl Cyanoacrylate for the palliative and/or adjuvant treatment of painful bone metastases not primarily amenable to surgery. Material and Methods. From January 2003 to December 2009, 243 patients (148 men and 95 women; age range, 20–87 years) with painful bone metastases were treated with N-2-butyl Cyanoacrylate. Overall, 309 embolizations were performed; 56 patients had more than one embolization. Embolizations were performed in the pelvis (168 procedures), in the spine (83 procedures), in the upper limb (13 procedures), in the lower limb (38 procedures) and in the thoracic cage (21 procedures). Primary cancer included urogenital, breast, gastrointestinal, thyroid, lung, musculoskeletal, skin, nerve and unknown origin.
Seven patients who had malignant proximal femoral tumours were selected for resection and limb salvage with a modular megaprosthesis. Histopathological diagnosis confirmed one solitary bone metastasis from
