Patients with soft-tissue sarcoma (STS) who undergo unplanned excision (UE) are reported to have worse outcomes than those who undergo planned excision (PE). However, others have reported that patients who undergo UE may have similar or improved outcomes. These discrepancies are likely to be due to differences in characteristics between the two groups of patients. The aim of the study is to compare patients who underwent UE and PE using propensity score matching, by analyzing data from the Japanese Bone and Soft Tissue Tumor (BSTT) registry. Data from 2006 to 2016 was obtained from the BSTT registry. Only patients with STS of the limb were included in the study. Patients with distant metastasis at the initial presentation and patients with dermatofibrosarcoma protuberans and well-differentiated liposarcoma were excluded from the study.Aims
Methods
The aim of this study was to determine whether
the high-sensitivity modified Glasgow prognostic score (Hs-mGPS) could
predict the disease-specific survival and oncological outcome in
adult patients with non-metastatic soft-tissue sarcoma before treatment.
A total of 139 patients treated between 2001 and 2012 were retrospectively reviewed.
The Hs-mGPS varied between 0 and 2. Patients with a score of 2 had
a poorer disease-specific survival than patients with a score of
0 (p <
0.001). The estimated five-year rate of disease-specific
survival for those with a score of 2 was 0%, compared with 85.4%
(95% CI 77.3 to 93.5) for those with a score of 0. Those with a
score of 2 also had a poorer disease-specific survival than those
with a score of 1 (75.3%, 95% CI 55.8 to 94.8; p <
0.001). Patients
with a score of 2 also had a poorer event-free rate than those with
a score of 0 (p <
0.001). Those with a score of 2 also had a
poorer event-free survival than did those with a score of 1 (p =
0.03). A multivariate analysis showed that the Hs-mGPS remained
an independent predictor of survival and recurrence. The Hs-mGPS
could be a useful prognostic marker in patients with a soft-tissue
sarcoma. Cite this article:
The aim of this study was to define the incidence
of venous thromboembolism (VTE) and risk factors for the development
of deep-vein thrombosis (DVT) after the resection of a musculoskeletal
tumour. A total of 94 patients who underwent resection of a musculoskeletal
tumour between January 2003 and December 2005 were prospectively
studied. There were 42 men and 52 women with a mean age of 54.4
years (18 to 86). All patients wore intermittent pneumatic compression
devices and graduated compression stockings. Ultrasound examination
of the lower limbs was conducted to screen for DVT between the fifth
and ninth post-operative days. DVT was detected in 21 patients (22%). Of these, two were symptomatic
(2%). One patient (1%) had a fatal pulmonary embolism. Patients
aged ≥ 70 years had an increased risk of DVT (p = 0.004). The overall incidence of DVT (both symptomatic and asymptomatic)
after resection of a musculoskeletal tumour with mechanical prophylaxis
was high. It seems that both mechanical and anticoagulant prophylaxis
is needed to prevent VTE in patients who have undergone the resection
of a musculoskeletal tumour. Cite this article:
Amalignant peripheral nerve-sheath tumour developed in the right S1 nerve root in a man aged 30 causing back pain and sciatica. CT and MRI revealed a destructive tumour of the sacrum invading the retroperitoneal space. The tumour was not resectable with an adequate margin. Chemotherapy, consisting of high-dose ifosfamide followed by a combination of vincristine, doxorubicin and cyclophosphamide, was given with success. Malignant peripheral nerve-sheath tumours are thought to respond weakly to chemotherapy, but the response in our patient was complete.
