RESUMEN
Ultra-low-dose computed tomography (ULD-CT) may combine the high sensitivity of conventional computed tomography (CT) in detecting sarcoma pulmonary metastasis, with a radiation dose in the same magnitude as chest X-ray (CXR). Fifty patients with non-metastatic high-grade soft tissue sarcoma treated with curative intention were recruited. Their follow-up involved both CXR and ULD-CT to evaluate their different sensitivity. Suspected findings were confirmed by conventional CT if necessary. Patients with isolated pulmonary metastases were treated with surgery or stereotactic body radiation therapy (SBRT) with curative intent if possible. The median effective dose from a single ULD-CT study was 0.27 mSv (range 0.12 to 0.89 mSv). Nine patients were diagnosed with asymptomatic lung metastases during the follow-up. Only three of them were visible in CXR and all nine in ULD-CT. CXR had therefore only a 33% sensitivity compared to ULD-CT. Four patients were operated, and one had SBRT to all pulmonary lesions. Eight of them, however, died of the disease. Two patients developed symptomatic metastatic recurrence involving extrapulmonary sites+/-the lungs between two imaging rounds. ULD-CT has higher sensitivity for the detection of sarcoma pulmonary metastasis than CXR, with a radiation dose considerably lower than conventional CT.Clinical trial registration: NCT05813808. 04-14-2023.

BACKGROUND: Craniosynostosis is a prevalent craniofacial malformation in Finland; however, comprehensive population-based epidemiological data are limited. This study aimed to estimate the total and birth prevalence of craniosynostosis in Finland from 1987 to 2010 and examine temporal trends. METHODS: We collected the data from nationwide registers maintained by the Finnish Institute for Health and Welfare and Statistics Finland, as well as treating hospitals, encompassing live births, stillbirths, terminations for fetal anomalies, and infant deaths with suspected or diagnosed craniosynostosis or skull deformation. A craniofacial surgeon and a clinical geneticist reviewed 1878 medical records for diagnostic confirmation. RESULTS: Out of 877 craniosynostosis cases, 83% were single-suture synostoses (all live births), 10% craniosynostosis syndromes, and 7% multisutural non-syndromic synostoses. Live birth prevalence from 1987 to 2010 was 6.0/10,000 live births, ranging from 5.0/10,000 in 1987 to 7.5/10,000 in 2010. Total prevalence, including live births, stillbirths, and terminations, varied from 5.0/10,000 in 1987 to 8.0/10,000 in 2010. Sagittal synostosis was the most common synostosis, with a prevalence of 3.9/10,000 live births, followed by metopic (0.6/10,000), unicoronal (0.4/10,000), and unilambdoid (0.1/10,000) synostoses. CONCLUSIONS: The total combined prevalence of all craniosynostosis types significantly increased driven by a nonsignificant rise across all subgroups and a significant increase in the syndrome group. In live births increase was significant only within the syndrome subgroup, primarily due to an increase in Muenke syndrome patients. The rising prevalence of syndromes necessitates further investigation. Contrasting with trends in Europe, Australia, and the USA, Finland showed no significant increase in metopic craniosynostosis.

Background: Sporadic venous malformation (VM) and angiomatosis of soft tissue (AST) are benign, congenital vascular anomalies affecting venous vasculature. Depending on the size and location of the lesion, symptoms vary from motility disturbances to pain and disfigurement. Due to the high recurrence of the lesions, more effective therapies are needed. Methods: As targeting stromal cells has been an emerging concept in anti-angiogenic therapies, here, by using VM/AST patient samples, RNA-sequencing, cell culture techniques, and a xenograft mouse model, we investigated the crosstalk of endothelial cells (EC) and fibroblasts and its effect on vascular lesion growth. Results: We report, for the first time, the expression and secretion of transforming growth factor A (TGFA) in ECs or intervascular stromal cells in AST and VM lesions. TGFA induced secretion of vascular endothelial growth factor (VEGF-A) in paracrine fashion, and regulated EC proliferation. Oncogenic PIK3CA variant in p.H1047R, a common somatic mutation found in these lesions, increased TGFA expression, enrichment of hallmark hypoxia, and in a mouse xenograft model, lesion size, and vascularization. Treatment with afatinib, a pan-ErbB tyrosine-kinase inhibitor, decreased vascularization and lesion size in a mouse xenograft model with ECs expressing oncogenic PIK3CA p.H1047R variant and fibroblasts. Conclusions: Based on the data, we suggest that targeting of both intervascular stromal cells and ECs is a potential treatment strategy for vascular lesions having a fibrous component.

BACKGROUND: Most sarcomas metastasize predominantly to the lungs, and chest x-ray, or computed tomography, is the most commonly used staging investigation. Myxoid liposarcomas (MLSs) are rare tumors with a tendency to metastasize to extrapulmonary loci. The aim of this study was to assess the locations of the first metastases in MLS patients, to guide the design of effective staging and follow-up imaging protocols. METHODS: Patients treated for MLS between 1987 and 2017 were identified in a prospectively maintained register. Histology of the tumors was reassessed. In addition, the presence of one of the pathognomonic gene translocations was confirmed, uniquely for a retrospective series. The surgical and oncological outcomes were reviewed. A comprehensive review of the literature was performed on the metastatic pattern of MLS, including series with 10 or more MLS patients with metastatic disease. RESULTS: A total of 32 patients with genetically confirmed MLS were identified, with a median follow-up of 7.6 years. Seven patients (22%) developed metastatic disease, five initially intra-abdominally and only one to the lungs. The comprehensive review included 14 series with 1853 patients, 348 (19%) of whom had metastases. The location of the first metastases was soft tissues in 32% of patients, intra-abdominal in 26%, pulmonary in 24%, and bone in 17%. CONCLUSIONS: MLSs metastasize often intra-abdominally and to extra-abdominal soft tissues. Thus, whole-body imaging may be indicated during the initial assessment and follow-up of these patients.

INTRODUCTION: Chondrosarcoma (CS) is most common primary osseous tumor of the chest wall. The aim of this study was to report results from surgical procedures and evaluate clinical factors predicting survival of patients with chest wall CSs treated in a single tertiary sarcoma center. MATERIALS AND METHODS: Fifty patients with primary CS located in the ribs and sternum were included. Details of the clinical data and oncological outcomes, including local recurrence (LR) and disease-specific survival (DSS), were collected. RESULTS: The tumor was primarily originated in the sternum in 6 patients (12.5%) and in ribs 2 to 11 in the remaining patients. Specimens were histologically graded 1 in 13 patients (26%), 2 in 28 (56%), 3 in 8 (16%), and 1 (2%) as mesenchymal grade 3 CS. R0 margins were obtained in all cases. Reconstruction was warranted in 47 (94%) cases. Local recurrence developed in 3 (6%) patients, and the median time to LR was 17 (range, 16-68) months. Eight (16%) patients developed metastasis. Increasing tumor volume was a statistically significant factor for reduction of DSS. CONCLUSIONS: Chondrosarcoma of the chest wall can be treated effectively with clear margins, resulting in lower LR rate and higher DSS than CS of the extremities and pelvis. Metastasis of the chest wall mostly occurs in high-grade tumors, and the locations of the metastases differ greatly from those observed in CS of the extremities and pelvis. Metastases are commonly extrapulmonary, indicating the need for postoperative follow-up with multiple imaging modalities to monitor recurrence and metastases.

Malignant peripheral nerve sheath tumor (MPNST) is a rare sarcoma with a poor prognosis, as the aggressive types of this cancer tend to grow rapidly and metastasize frequently. MPNST is associated with neurofibromatosis type 1 gene mutation. The minority of cases arise secondary to radiation therapy or sporadically. The primary treatment for MPNST is early surgical resection of the tumor. The aim of this study was to retrospectively evaluate the outcome of the treatment of MPNST in Helsinki University Hospital from the years 1991 to 2021. Fourteen MPNST cases were evaluated in this study retrospectively. Descriptive statistical analysis was performed on the collected patient data. Marginal resection was completed in nine cases, wide margins were achieved in three cases, and in two cases the final histological examination of the specimen revealed intralesional removal. During the follow-up time of 36.7 ± 12.1 months, all patients who underwent wide margin resection were alive. One patient died 22 months after intralesional resection and six within 38.3 ± 30.9 months of marginal resection. Seventy-one percent of tumor surgeries resulted in Clavien-Dindo class 3b complications, reflecting the complexity of the surgeries. The aggressive nature of MPNST and the large size of these tumors requires extensive surgery, which can lead to complications. The prognosis of MPNST needs improvement.

The prevalence of diabetes mellitus, particularly type 2 diabetes, is increasing worldwide. Also, the incidence of both lower limb revascularizations and amputations is increasing. We have less transtibial amputations due to improved diabetes care, but also due to modern treatments, vascular surgery, and development of plastic surgery. With well-planned minor amputations, more limbs can be saved. Minor limb-saving amputations are preferred especially to older diabetes patients, because they have a high-risk contralateral amputations. Losing both limbs causes major problems for patients and their life, risk for lifetime ward is high.

BACKGROUND: Surgical resection of soft tissue sarcoma with a margin of healthy tissue may necessitate resection and reconstruction of major blood vessels together with soft tissues of the proximal thigh to preserve the limb. The long-term functional outcomes of these reconstructions remain unestablished. The aim of this report was to assess the vascular and functional outcomes of soft tissue sarcoma patients with femoral vessel reconstructions. PATIENTS AND METHODS: Patients who had undergone oncovascular reconstruction during the treatment of proximal thigh soft tissue sarcoma in 2014-2020 were reviewed for details of the vascular and soft tissue reconstructions, and the oncological and functional outcomes. This included eight patients of a median age 59 (range 19-77) years. All had a reconstruction of at least the superficial femoral artery and vein as well as soft tissue reconstruction with a muscle flap. All vessel reconstructions were done with either autologous vein (six grafts/four patients) or allograft (10 grafts/six patients). A microvascular latissimus dorsi flap, with a skin island, was incorporated to cover the vascular grafts in five patients. A pedicled sartorius or gracilis muscle flap was used to fill the defect in three patients. RESULTS: Graft patency was assessed in seven patients with a median follow-up of 48 (1-76) months. The arterial graft was patent in 6/8 and the vein graft in 2/8 patients. The gait had returned to normal in five of the six patients assessed. The median MTSS was 70 (43-87)% and the TESS 90 (75-100)%. No local recurrence of the sarcoma was detected. CONCLUSIONS: Vascular reconstruction combined with soft tissue reconstruction enables limb-sparing surgery in patients with soft tissue sarcoma involving proximal femoral vessels. Although the surgeries are complex with high early morbidity, the achieved long-term functional outcomes are worthwhile.

Background: Ki-67 is a widely used proliferation marker reflecting prognosis in various tumors. However, visual assessment and scoring of Ki-67 suffers from marked inter-observer and intra-observer variability. We aimed to assess the concordance of manual counting and automated image-analytic scoring methods for Ki-67 in synovial sarcoma. Patients and Methods: Tissue microarrays from 34 patients with synovial sarcoma were immunostained for Ki-67 and scored both visually and with 3DHistech QuantCenter. Results: The automated assessment of Ki-67 expression was in good agreement with the visually counted Ki-67 (r Pearson =0.96, p<0.001). In a Cox regression model automated [hazard ratio (HR)=1.047, p=0.024], but not visual (HR=1.063, p=0.053) assessment method associated high Ki-67 scores with worse overall survival. Conclusion: The automated Ki-67 assessment method appears to be comparable to the visual method in synovial sarcoma and had a significant association to overall survival.
RESUMEN
BACKGROUND/AIM: The aim of this prospective study was to determine whether serum Thymidine kinase -1 (TK1) could serve as a tumor marker in soft tissue sarcomas (STS). PATIENTS AND METHODS: A total of 48 patients diagnosed with localized STS were included. None had received preoperative oncological treatment. Samples were collected before and after surgery and TK1 levels measured with the AroCell TK210 ELISA. RESULTS: Mean preoperative TK1 was 0.32 µg/l, range=0.11-1.47, and 18 cases (38%) had values above the reference limit (0.41 µg/l). Mean postoperative TK1 was 0.35 µg/l (0.06-0.86). In patients with preoperative values above the reference limit, TK1 decreased significantly after surgery (n=13, p=0.001). We found no association between increased preoperative TK1 and age, sex, tumor size, grade, and the presence of vascular invasion or necrosis. CONCLUSION: TK1 has limited use as a tumor marker in localized STS.

Interest in functional outcome (FO) and health-related quality of life (HRQL) in extremity soft-tissue sarcoma (STS) patients has increased. The aim of this study was to validate two FO questionnaires for upper extremity STS patients: the Toronto Extremity Salvage Score (TESS) and short version of the Disability of Arm, Shoulder and Hand (QuickDASH), based on Finnish population data. A multi-center study was conducted at two academic sarcoma centers. Surgically treated upper extremity STS patients were invited to participate. Patients completed the TESS and the QuickDASH with HRQL questionnaires the 15D and the QLQ-C30. The scores were analyzed and compared. Fifty-five patients with a mean follow-up period of 4.7 years were included. Mean age was 63 years (standard deviation [SD] 14.6). The mean score for TESS was 88.5 (SD 15.1) and for QuickDASH 17.8 (SD 19.6). The QuickDASH had a statistically significantly better score coverage. A ceiling effect was noted, 27% and 20% for TESS and QuickDASH, respectively. The TESS and QuickDASH scores were strongly correlated (r= -0.89). The TESS score strongly correlated with the QLQ-C30 (r = 0.79) and the 15D score (r = 0.70). The QuickDASH score correlated strongly with the QLQ-C30 score (r=-0.71) and moderately with the 15D score (r= -0.56). The TESS score had a statistically significantly stronger correlation with the 15D score than QuickDASH (p<0.005). Both the TESS and the QuickDASH provide reliable scores for assessing FO in upper extremity STS patients. The QuickDASH has a better coverage, whereas TESS showed a stronger correlation to HRQL scores.

Massive weight loss might lead to excess skin folds causing functional, physical, and psychosocial discomfort. Following bariatric procedures, an increasing number of patients are seeking lower body contouring surgery (LBCS). The proportion of bariatric patients who undergo LBCS is largely unknown. The aim of this current study was to analyse the incidence and realization of LBCS in bariatric patients in Finland.National retrospective register linkage study including all adult patients who received bariatric surgery in Finland during 1998-2016. The data were obtained from the Finnish national health registers maintained by the Finnish Institute for Health and Welfare. Altogether 1089 (14.1%) of 7703 bariatric patients underwent LBCS during the study period. The majority of the LBCS procedures were abdominoplasty (89%). Median latency between bariatric surgery and LBCS was 31 months. The patients with LBCS were younger (p < 0.001) and received sleeve gastrectomy (p < 0.001). We revealed an annual correlation between LBCS and bariatric procedures (r = 0.683). With a two-year latency between the bariatric and post-bariatric operations, the correlation co-efficiency was strong (r = 0.927). LBCS operations ranged from 5 to 215 per hospital district. Most LBCSs (97.3%) were performed in public hospitals, and some (41%) were performed in university hospitals. This study shows that only 14.1% of bariatric patients undergo LBCS. There is a correlation between bariatric procedures and succeeding plastic surgical reconstructive procedures.

BACKGROUND: Few studies have focused on patient-related factors in analyzing long-term functional outcome and health-related quality of life (HRQoL) in patients with postoperative lower extremity soft tissue sarcoma (STS). OBJECTIVE: The purpose of this study was to investigate factors associated with postoperative functional outcome and HRQoL in patients with lower extremity STS. METHODS: This cross-sectional study was performed in a tertiary referral center using the Toronto Extremity Salvage Score (TESS), Quality-of-Life Questionnaire (QLQ)-C30 and 15 Dimension (15D) measures. Functional outcome and HRQoL data were collected prospectively. All patients were treated by a multidisciplinary team according to a written treatment protocol. RESULTS: A total of 141 patients who had undergone limb-salvage surgery were included. Depending on the outcome measure used, 19-51% of patients were completely asymptomatic and 13-14% of patients had an unimpaired HRQoL. The mean score for TESS, 15D mobility score, and QLQ-C30 Physical Functioning scale were 86, 0.83, and 75, respectively, while the mean score for 15D was 0.88, and 73 for QLQ-C30 QoL. Lower functional outcome was statistically significantly associated with higher age, higher body mass index (BMI), and the need for reconstructive surgery and radiotherapy, while lower HRQoL was statistically significantly associated with higher age, higher BMI, and reconstructive surgery. CONCLUSION: Functional outcome and HRQoL were generally high in this cross-sectional study of patients with STS in the lower extremity. Both tumor- and treatment-related factors had an impact but patient-related factors such as age and BMI were the major determinants of both functional outcome and HRQoL.

BACKGROUND: Obesity in fertile age women has increased worldwide leading to increased bariatric procedures. Lower body contouring surgery (LBCS) is one of the most commonly performed esthetic operations, mainly owing to massive weight loss. However, there is a paucity of data regarding pregnancy and delivery after LBCS. In this study, we examined whether LBCS influences pregnancy or delivery and mother and baby outcome. METHODS: In this national registry-based study, we used data from the Finnish Institute of Health and Welfare and the Causes of Death registry. We included fertile age women, from 18 to 54 years who had LBCS with or without a bariatric procedure and who experienced pregnancy and delivery were compared to all deliveries in Finland during 1999- 2016. RESULTS: We identified 92 women who had LBCS before delivery. These 92 women had planned cesarean sections more often (P < .001) and preterm delivery was more common (P < .001). None of the mothers or babies died. Of the 92 women, 26 had a preceding bariatric procedure. The preceding bariatric procedures did not increase the risk for preterm delivery or low birth weight. The need for urgent or emergency sections was not increased. The heightened number of planned cesareans is caused by the different demographics of the study group, indicating that previous LBCS is not a contraindication for vaginal delivery. CONCLUSION: Pregnancy and delivery are safe for the mother and the baby after LBCS. The possible deviations from normal pregnancy and delivery should be discussed with fertile age women seeking LBCS.

The most widely used patient-reported outcome (PRO) measure for soft tissue sarcoma (STS) patients is the Toronto Extremity Salvage Score (TESS). The aim of the study was to validate and test the reliability of the TESS for patients with lower extremity STS based on Finnish population data. Patients were assessed using the TESS, the QLQ-C30 Function and Quality of life (QoL) modules, the 15D and the Musculoskeletal tumour Society (MSTS) score. The TESS was completed twice with a 2- to 4-week interval. The intraclass correlation coefficient (ICC) was used for test-retest reliability. Construct validity was tested for structural validity and convergent validity. Altogether 136 patients completed the TESS. A ceiling effect was noted as 21% of the patients scored maximum points. The ICC between first and second administration of the TESS was 0.96. The results of exploratory factor analysis together with high Cronbach's alpha (0.98) supported a unidimensional structure. The TESS correlated moderately with the MSTS score (rhoâ¯=â¯0.59, p< 0.001) and strongly with the mobility dimension in the 15D HRQL instrument (rhoâ¯=â¯0.76, p < 0.001) and the physical function in QLQ-C30 (rhoâ¯=â¯0.83, p< 0.001). The TESS instrument is a comprehensive and reliable PRO measure. The TESS may be used as a validated single index score, for lower extremity STS patients for the measurement of a functional outcome. The TESS seems to reflect patients' HRQoL well after the treatment of lower extremity soft tissue sarcomas.

OBJECTIVE: Radical excision of retroperitoneal or intra-abdominal soft tissue sarcomas may necessitate vessel resection and reconstruction. The aim of this study was to assess surgical results of retroperitoneal or intra-abdominal sarcomas involving major blood vessels. METHODS: This was a retrospective single centre cohort study and a comprehensive review of literature. Patients with retroperitoneal or intra-abdominal sarcomas treated by the oncovascular team in Helsinki University Hospital from 2010 to 2018 were reviewed for vascular and oncological outcomes. A comprehensive literature review of vascular reconstructions in patients with retroperitoneal sarcoma was performed. RESULTS: Vascular reconstruction was performed in 17 patients, 11 of whom required arterial reconstructions. Sixteen of the operations were sarcoma resections; the post-operative diagnosis for one patient was thrombosis instead of the presumed recurrent leiomyosarcoma. Early graft thrombosis occurred in two venous and one arterial reconstruction. Late thrombosis was detected in three (18%). The median follow up was 27 (range 0-82) months. Of the patients with sarcoma resections 5 (31%) died of sarcoma and further 4 (25%) developed local recurrence or new distant metastases. The comprehensive review of literature identified 37 articles with 110 patients, 89 of whom had inferior vena cava reconstruction only. Eight arterial reconstructions were described. Late graft thrombosis occurred in 14%. The follow up was 0-181 months, during which 57% remained disease free and 7% died of sarcoma. CONCLUSION: Vascular reconstructions enable radical resection of retroperitoneal and intra-abdominal sarcomas in patients with advanced disease. The complex operations are associated with an acceptable rate of serious peri-operative complications and symptomatic thrombosis of the repaired vessel is rare. However, further studies are needed to assess the performance of the vascular reconstructions in the long term.

BACKGROUND AND OBJECTIVES: Liposarcomas form a diverse group of tumors that represent the majority of retroperitoneal soft tissue sarcomas. Radical excision of these retroperitoneal liposarcomas is often challenging due to their large size and proximity to visceral organs and major vessels. Here we present the 30-year experience of our multidisciplinary sarcoma team in the treatment of these tumors and analysis of factors influencing survival. METHODS: Patients with retroperitoneal liposarcomas treated in Helsinki University Hospital from 1987 to 2017 were reviewed. Local recurrence-free survival, metastases-free survival, and disease-specific survival were assessed with Kaplan-Meier analysis, and factors influencing survival were evaluated with Cox regression. RESULTS: A total of 107 patients were identified. The median follow-up time was 5.4 years (interquartile range: 2.2-8.8 years). Local recurrence developed in 72% and metastases in 15% during follow-up. The 5-year disease-free survival was 31% and disease-specific survival was 66%. The multifactorial analysis revealed histological type and grade as predictors of disease-specific survival (P < .01) while multifocality carried a poor prognosis for local recurrence (P = .02) and higher histological grade for metastases (P < .01). CONCLUSIONS: Retroperitoneal liposarcomas rarely metastasize but tend to recur locally. For tumors that have been resected with macroscopically clear margins, histological, type, and grade are significant predictors of survival.

OBJECTIVE: This study aimed to present the results of a series of forequarter amputations (FQAs) and to evaluate the reconstructive methods used. SUMMARY BACKGROUND DATA: Although FQA has become a rare procedure in the era of limb-sparing treatment of extremity malignancies, it is a useful option when resection of a shoulder girdle or proximal upper extremity tumor cannot be performed so as to retain a functional limb. METHODS: Thirty-four patients were treated with FQA in 1989 to 2017. Various reconstructive techniques were used, including free fillet flaps from the amputated extremity. RESULTS: All patients presented with intractable symptoms such as severe pain, motor or sensory deficit, or limb edema. Seventeen patients were treated with palliative intent. Chest wall resection was performed in 9 patients. Free flap reconstruction was necessary for 15 patients, with 11 free flaps harvested from the amputated extremity. There was no operative mortality, and no free flaps were lost. In curatively treated patients, estimated 5-year disease-specific survival was 60%. Median survival in the palliatively treated group was 13 months (1-35 months). CONCLUSIONS: Limb-sparing treatment is preferable for most shoulder girdle and proximal upper extremity tumors. Sometimes, FQA is the only option enabling curative treatment. In palliative indications, considerable disease-free intervals and relief from disabling symptoms can be achieved. The extensive tissue defects caused by extended FQA can be safely and reliably reconstructed by means of free flaps, preferably harvested from the amputated extremity.

BACKGROUND: Radiation-associated angiosarcoma of the breast (RAASB) is an aggressive malignancy that is increasing in incidence. Only a few previous population-based studies have reported the results of RAASB treatment. METHODS: A search for RAASB patients was carried out in the Finnish Cancer Registry, and treatment data were collected to identify prognostic factors for survival. RESULTS: Overall, 50 RAASB patients were identified. The median follow-up time was 5.4 years (range 0.4-15.6), and the 5-year overall survival rate was 69%. Forty-seven (94%) patients were operated on with curative intent. Among these patients, the 5-year local recurrence-free survival, distant recurrence-free survival, and overall survival rates were 62%, 75%, and 74%, respectively. A larger planned surgical margin was associated with improved survival. CONCLUSIONS: We found that the majority of RAASB patients were eligible for radical surgical management in this population-based analysis. With radical surgery, the prognosis is relatively good.
