Current literature suggests that survival outcomes and local recurrence rates of primary soft-tissue sarcoma diagnosed in the very elderly age range, (over 90 years), are comparable with those in patients diagnosed under the age of 75 years. Our aim is to quantify these outcomes with a view to rationalizing management and follow-up for very elderly patients. Retrospective access to our prospectively maintained oncology database yielded a cohort of 48 patients across 23 years with a median follow-up of 12 months (0 to 78) and mean age at diagnosis of 92 years (90 to 99). Overall, 42 of 48 of 48 patients (87.5%) were managed surgically with either limb salvage or amputation.Aims
Methods
Aims. The incidence of bone metastases is between 20% to 75% depending on the type of cancer. As treatment improves, the number of patients who need surgical intervention is increasing. Identifying patients with a shorter life expectancy would allow surgical intervention with more durable reconstructions to be targeted to those most likely to benefit. While previous scoring systems have focused on surgical and oncological factors, there is a need to consider
Due to their radiolucency and favourable mechanical properties, carbon fibre nails may be a preferable alternative to titanium nails for oncology patients. We aim to compare the surgical characteristics and short-term results of patients who underwent intramedullary fixation with either a titanium or carbon fibre nail for pathological long-bone fracture. This single tertiary-institutional, retrospectively matched case-control study included 72 patients who underwent prophylactic or therapeutic fixation for pathological fracture of the humerus, femur, or tibia with either a titanium (control group, n = 36) or carbon fibre (case group, n = 36) intramedullary nail between 2016 to 2020. Patients were excluded if intramedullary fixation was combined with any other surgical procedure/fixation method. Outcomes included operating time, blood loss, fluoroscopic time, and complications. Fisher’s exact test and Mann-Whitney U test were used for categorical and continuous outcomes, respectively.Aims
Methods
The modern prevalence of primary tumours causing metastatic bone disease is ill-defined in the oncological literature. Therefore, the purpose of this study is to identify the prevalence of primary tumours in the setting of metastatic bone disease, as well as reported rates of pathological fracture, postoperative complications, 90-day mortality, and 360-day mortality for each primary tumour subtype. The Premier Healthcare Database was queried to identify all patients who were diagnosed with metastatic bone disease from January 2015 to December 2020. The prevalence of all primary tumour subtypes was tabulated. Rates of long bone pathological fracture, 90-day mortality, and 360-day mortality following surgical treatment of pathological fracture were assessed for each primary tumour subtype. Patient characteristics and postoperative outcomes were analyzed based upon whether patients had impending fractures treated prophylactically versus treated completed fractures.Aims
Methods
The risk of postoperative complications after resection of soft-tissue sarcoma in the medial thigh is higher than in other locations. This study investigated whether a vessel sealing system (VSS) could help reduce the risk of postoperative complications after wide resection of soft-tissue sarcoma in the medial thigh. Of 285 patients who underwent wide resection for soft-tissue sarcoma between 2014 and 2021 at our institution, 78 patients with tumours in the medial thigh were extracted from our database. Information on clinicopathological characteristics, preoperative treatment, surgical treatment (use of VSS, blood loss volume, operating time), and postoperative course (complications, postoperative haemoglobin changes, total drainage volume, and drainage and hospitalization durations) were obtained from medical records. We statistically compared clinical outcomes between patients whose surgery did or did not use VSS (VSS and non-VSS groups, respectively).Aims
Methods
Surgical site infection (SSI) after soft-tissue sarcoma (STS) resection is a serious complication. The purpose of this retrospective study was to investigate the risk factors for SSI after STS resection, and to develop a nomogram that allows patient-specific risk assessment. A total of 547 patients with STS who underwent tumour resection between 2005 and 2021 were divided into a development cohort and a validation cohort. In the development cohort of 402 patients, the least absolute shrinkage and selection operator (LASSO) regression model was used to screen possible risk factors of SSI. To select risk factors and construct the prediction nomogram, multivariate logistic regression was used. The predictive power of the nomogram was evaluated by receiver operating curve (ROC) analysis in the validation cohort of 145 patients.Aims
Methods
This study aimed to compare the performance of survival prediction models for bone metastases of the extremities (BM-E) with pathological fractures in an Asian cohort, and investigate patient characteristics associated with survival. This retrospective cohort study included 469 patients, who underwent surgery for BM-E between January 2009 and March 2022 at a tertiary hospital in South Korea. Postoperative survival was calculated using the PATHFx3.0, SPRING13, OPTIModel, SORG, and IOR models. Model performance was assessed with area under the curve (AUC), calibration curve, Brier score, and decision curve analysis. Cox regression analyses were performed to evaluate the factors contributing to survival.Aims
Methods
We first sought to compare survival for patients treated surgically for solitary and multiple metastases in the appendicular skeleton, and second, to explore the role of complete and incomplete resection (R0 and R1/R2) in patients with a solitary bony metastasis in the appendicular skeleton. We conducted a retrospective study on a population-based cohort of all adult patients treated surgically for bony metastases of the appendicular skeleton between January 2014 and December 2019. We excluded patients in whom the status of bone metastases and resection margin was unknown. Patients were followed until the end of the study or to their death. We had no loss to follow-up. We used Kaplan-Meier analysis (with log-rank test) to evaluate patient survival. We identified 506 operations in 459 patients. A total of 120 operations (in 116 patients) were for solitary metastases and 386 (in 345 patients) for multiple metastases. Of the 120 operations, 70 (in 69 patients) had no/an unknown status of visceral metastases (solitary group) and 50 (in 49 patients) had visceral metastases. In the solitary group, 45 operations (in 44 patients) were R0 (resections for cure or complete remission) and 25 (in 25 patients) were R1/R2 (resections leaving microscopic or macroscopic tumour, respectively). The most common types of cancer in the solitary group were kidney (n = 27), lung (n = 25), and breast (n = 20).Aims
Methods
Clear cell sarcoma (CCS) of soft-tissue is a rare melanocytic subtype of mesenchymal malignancy. The aim of this study was to investigate the clinical and therapeutic factors associated with increased survival, stratified by clinical stage, in order to determine the optimal treatment. The study was a retrospective analysis involving 117 patients with histologically confirmed CCS, between July 2016 and November 2017, who were enrolled in the Bone and Soft Tissue Tumour Registry in Japan.Aims
Methods
The primary objective of this study was to compare the postoperative infection rate between negative pressure wound therapy (NPWT) and conventional dressings for closed incisions following soft-tissue sarcoma (STS) surgery. Secondary objectives were to compare rates of adverse wound events and functional scores. In this prospective, single-centre, randomized controlled trial (RCT), patients were randomized to either NPWT or conventional sterile occlusive dressings. A total of 17 patients, with a mean age of 54 years (21 to 81), were successfully recruited and none were lost to follow-up. Wound reviews were undertaken to identify any surgical site infection (SSI) or adverse wound events within 30 days. The Toronto Extremity Salvage Score (TESS) and Musculoskeletal Tumor Society (MSTS) score were recorded as patient-reported outcome measures (PROMs).Aims
Methods
Time to treatment initiation (TTI) is generally defined as the time from the histological diagnosis of malignancy to the initiation of first definitive treatment. There is no consensus on the impact of TTI on the overall survival in patients with a soft-tissue sarcoma. The purpose of this study was to determine if an increased TTI is associated with overall survival in patients with a soft-tissue sarcoma, and to identify the factors associated with a prolonged TTI. We identified 23,786 patients from the National Cancer Database who had undergone definitive surgery between 2004 and 2015 for a localized high-grade soft-tissue sarcoma of the limbs or trunk. A Cox proportional hazards model was used to examine the relationship between a number of factors and overall survival. We calculated the incidence rate ratio (IRR) using negative binomial regression models to identify the factors that affected TTI.Aims
Methods
Hip reconstruction after resection of a periacetabular chondrosarcoma is complex and associated with a high rate of complications. Previous reports have compared no reconstruction with historical techniques that are no longer used. The aim of this study was to compare the results of tantalum acetabular reconstruction to both historical techniques and no reconstruction. We reviewed 66 patients (45 males and 21 females) with a mean age of 53 years (24 to 81) who had undergone acetabular resection for chondrosarcoma. A total of 36 patients (54%) underwent acetabular reconstruction, most commonly with a saddle prosthesis (n = 13; 36%) or a tantalum total hip arthroplasty (THA) (n = 10; 28%). Mean follow-up was nine years (SD 4).Aims
Methods
Survival rates and local control after resection of a sarcoma of the pelvis compare poorly to those of the limbs and have a high incidence of complications. The outcome for patients who need a hindquarter amputation (HQA) to treat a pelvic sarcoma is poor. Our aim was to evaluate the patient, tumour, and reconstructive factors that affect the survival of the patients who undergo HQA for primary or recurrent pelvic sarcoma. We carried out a retrospective review of all sarcoma patients who had undergone a HQA in a supraregional sarcoma unit between 1996 and 2018. Outcomes included oncological, surgical, and survival characteristics.Aims
Methods
Although internal hemipelvectomy is associated with a high incidence of morbidity, especially wound complications, few studies have examined rates of wound complications in these patients or have identified factors associated with the consequences. The present study aimed to: 1) determine the rate of wound and other complications requiring surgery after internal hemipelvectomy; and 2) identify factors that affect the rate of wound complications and can be used to stratify patients by risk of wound complications. The medical records of 123 patients undergoing internal hemipelvectomy were retrospectively reviewed, with a focus on both overall complications and wound complications. Logistic regression analyses were performed to examine the association between host, tumour, and surgical factors and rates of postoperative wound complications.Aims
Methods
The aim of this study was to evaluate health-related quality of life (HRQoL) and joint function in tenosynovial giant cell tumour (TGCT) patients before and after surgical treatment. This prospective cohort study run in two Dutch referral centres assessed patient-reported outcome measures (PROMs; 36-Item Short-Form Health Survey (SF-36), visual analogue scale (VAS) for pain, and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC)) in 359 consecutive patients with localized- and diffuse-type TGCT of large joints. Patients with recurrent disease (n = 121) and a wait-and-see policy (n = 32) were excluded. Collected data were analyzed at specified time intervals preoperatively (baseline) and/or postoperatively up to five years.Aims
Patients and Methods
The purpose of this retrospective study was to differentiate
between the MRI features of normal post-operative change and those
of residual or recurrent disease after intralesional treatment of
an atypical cartilage tumour (ACT)/grade I chondrosarcoma. We reviewed the case notes, radiology and histology of 75 patients,
who had been treated for an ACT/grade I chondrosarcoma by curettage,
phenolisation and bone allografting between 1994 and 2005. The first
post-operative Gd-enhanced MRI scan was carried out within one year
of surgery. Patients had a minimum of two scans and a mean follow-up
of 72 months (13 to 169). Further surgery was undertaken in cases
of suspected recurrence.Aims
Patients and Methods
The aim of this study was to establish what happens to patients
in the long term after endoprosthetic replacement for a primary
malignant tumour of bone. We conducted a retrospective analysis of a prospectively maintained
database to identify all patients who had undergone an endoprosthetic
replacement more than 25 years ago and who were still alive. Their
outcomes were investigated with reference to their complications and
need for further surgery. A total of 230 patients were identified.
Their mean age at diagnosis was 20.7 years (five to 62). The most
common diagnosis was osteosarcoma (132). The most common site was
the distal femur (102). Aims
Patients and Methods
Osteosarcoma of the pelvis is a particularly difficult tumour
to treat as it often presents late, may be of considerable size
and/or associated with metastases when it presents, and is frequently
chondroid in origin and resistant to chemotherapy. The aim of this study was to review our experience of managing
this group of patients and to identify features predictive of a
poor outcome. Between 1983 and 2014, 121 patients, (74 females and 47 males)
were treated at a single hospital: 74 (61.2%) patients had a primary
osteosarcoma and 47 (38.8%) had an osteosarcoma which was secondary
either to Paget’s disease (22; 18.2%) or to previous pelvic irradiation
(25; 20.7%). The mean age of those with a primary osteosarcoma was 29.3 years
(nine to 76) and their mean follow-up 2.9 years (0 to 29). The mean
age of those with a secondary sarcoma was 61.9 years (15 to 85)
and their mean follow-up was one year (0 to 14). A total of 22 patients with a primary sarcoma (52.4%) and 20
of those with a secondary sarcoma (47.6%) had metastases at the
time of presentation. Aims
Patients and Methods
Patients who have limb amputation for musculoskeletal
tumours are a rare group of cancer survivors. This was a prospective
cross-sectional survey of patients from five specialist centres
for sarcoma surgery in England. Physical function, pain and quality
of life (QOL) outcomes were collected after lower extremity amputation
for bone or soft-tissue tumours to evaluate the survivorship experience
and inform service provision. Of 250 patients, 105 (42%) responded between September 2012 and
June 2013. From these, completed questionnaires were received from
100 patients with a mean age of 53.6 years (19 to 91). In total
60 (62%) were male and 37 (38%) were female (three not specified).
The diagnosis was primary bone sarcoma in 63 and soft-tissue tumour
in 37. A total of 20 tumours were located in the hip or pelvis,
31 above the knee, 32 between the knee and ankle and 17 in the ankle
or foot. In total 22 had hemipelvectomy, nine hip disarticulation,
35 transfemoral amputation, one knee disarticulation, 30 transtibial
amputation, two toe amputations and one rotationplasty. The Toronto
Extremity Salvage Score (TESS) differed by amputation level, with
poorer scores at higher levels (p <
0.001). Many reported significant
pain. In addition, TESS was negatively associated with increasing
age, and pain interference scores. QOL for Cancer Survivors was
significantly correlated with TESS (p <
0.001). This relationship appeared
driven by pain interference scores. This unprecedented national survey confirms amputation level
is linked to physical function, but not QOL or pain measures. Pain
and physical function significantly impact on QOL. These results
are helpful in managing the expectations of patients about treatment
and addressing their complex needs. Cite this article:
It is important to be able to identify patients
with an increased risk of venous thromboembolism (VTE) in order
to minimise the risk of an event. We investigated the incidence
and risk factors for post-operative VTE in 168 consecutive patients
with a malignancy of the lower limb. The period of study included
ten months before and 12 months after the introduction of chemical
thromboprophylaxis. All data about the potential risk factors were identified
and classified into three groups (patient-, surgery- and tumour-related).
The outcome measure was a thromboembolic event within 90 days of
surgery. Of the 168 patients, eight (4.8%) had a confirmed symptomatic
deep-vein thrombosis and one (0.6%) a fatal pulmonary embolism.
Of the 28 variables tested, age >
60 years, higher American Society
of Anesthesiologists grade and metastatic tumour were independent
risk factors for VTE. The overall rate of symptomatic VTE was not significantly
different between patients who received chemical thromboprophylaxis
and those who did not. Knowledge of these risk factors may be of
value in improving the surgical outcome of patients with a malignancy
of the lower limb. Cite this article:
