Delayed gastric emptying (DGE) is a common complication in surgery, but incidence and relevance following multivisceral resection are unknown.Data from 100 consecutive patients treated for primary retroperitoneal sarcoma (RPS) were analyzed from our institutional prospectively maintained database from January 2019 to April 2020. DGE severity was graded according to the International Study Group of Pancreatic Surgery and classified as primary or secondary to other complications. The primary outcome was incidence and grade of clinically relevant DGE (grades B-C). Secondary outcomes were correlation with patient, tumor, and treatment characteristics, and non-DGE morbidity [Clavien-Dindo (CD) grade ≥ 3].Forty-two patients developed DGE and 28 had clinically relevant DGE. DGE was primary in 10 patients and secondary in 18 patients; the most common associated complications were: infections (11/18, 61.1%), pancreatic leak (7/18, 38.9%), bleeding (6/18, 33.3%), and bowel leak (6/18, 33.3%). DGE was related to longer length of hospital stay (P0.001), ICU admission (P = 0.004), ICU length of stay (P = 0.001), postoperative complications (CD [Formula: see text] 3 in 14/28 in DGE patients vs 11/72 in no-DGE; P = 0.04), and re-operation (P = 0.03). With multivariate analysis, the independent risk factors for DGE were patient comorbidities (OR 1.05; 95% CI 1.01-1.1; P = 0.04) and tumor size (OR 1.05; 95% CI 1.0-1.1; P = 0.02).Following multivisceral resection, DGE is a clinically relevant event that can be caused by an underlying complication. Prompt diagnosis and treatment of both DGE and any underlying complications led to full recovery in all cases.

limb-sparing surgery is the mainstream treatment for primary extremity soft tissue sarcoma (ESTS) at referral centers, following advances in surgical reconstructions and multimodal management. However, amputation is still needed in selected patients and has not yet been described for a ESTS cohort in a contemporary scenario.consecutive patients who underwent surgery for primary ESTS from 2006 to 2018 were extracted from a prospectively collected database at our reference center. Patients receiving amputation for either primary tumor or local recurrence (LR) after limb-sparing surgery were selected for analysis.Among 1628 primary ESTS, 29 patients underwent primary amputation (1.8%), 22/1159 (1.9%) for upper limb and 7/469 (1.5%) for lower limb ESTS. Patients were mainly affected by grade III FNCLCC (89.6%) of notable dimension (median size 16 cm, IQR 10-24). 65.5% of patients received preoperative treatments (systemic or regional chemotherapy, radiotherapy or chemo-radiation). Secondary amputation for LR was performed after a median of 23 months in 16/1599 patients (1%). Median survival time was 16.2 and 29.6 months after primary or secondary amputation respectively. Factors prompting the need for a primary amputation were most often a combination of multifocal disease, bone invasion and pain or neurovascular bundle involvement and relevant comorbidities, mainly for grade III tumors in elderly patients.Contemporary rate of amputation for ESTS at a reference center is extremely low. Still, amputation is required in selected cases with advanced presentations, especially in elderly, frail patients.

Contains fulltext : 235268.pdf (Publisher’s version ) (Open Access) BACKGROUND: Oesophageal gastrointestinal stromal tumours (GISTs) account for ≤1% of all GISTs. Consequently, evidence to guide clinical decision-making is limited. METHODS: Clinicopathological features and outcomes in patients with primary oesophageal GIST from seven European countries were collected retrospectively. RESULTS: Eighty-three patients were identified, and median follow up was 55.0 months. At diagnosis, 59.0% had localized disease, 25.3% locally advanced and 13.3% synchronous metastasis. A biopsy (Fine Needle aspiration n = 29, histological biopsy n = 31) was performed in 60 (72.3%) patients. The mitotic count was low (5/5hpf) mitotic count were associated with worse disease free survival. CONCLUSION: Based on the current study, enucleation can be recommended for oesophageal GIST smaller than 4 cm, while oesophagectomy should be preserved for larger tumours. Patients with larger tumours (>4 cm) and/or high mitotic count should be treated with adjuvant therapy.

Retroperitoneal liposarcomas are a rare entity and are comprised mostly of the well-differentiated and dedifferentiated subtypes. Eight-year survival ranges from 30% to 80% depending on histologic subtype and grade. Surgery is the cornerstone of treatment and compartment resection is the current standard. Mesenteric liposarcomas are extremely rare and comprise more high-grade lesions, with poorer prognosis of 50% 5-year overall survival. They are managed with a similar aggressive surgical approach. This review presents the current management of retroperitoneal and mesenteric liposarcomas.

Primary abdominal wall sarcomas are rare, heterogeneous tumours. The mainstay of management is surgery, although local recurrences (LR) and distant metastases (DM) are common.Overall survival (OS) and disease-free survival (DFS) were primary outcomes; factors associated with prognosis secondary outcomes.Patients undergoing surgery of primary abdominal wall sarcomas between April 2008 and May 2018 were identified at two referrals centres for sarcoma surgery. Patient demographics, tumour and treatment-related characteristics were recorded and analysed.A cohort of 65 patients underwent surgical resection with a median follow-up of 56 months, 5-year OS and DFS were 69% and 71%, respectively. Eleven patients (16.9%) experienced a recurrence event: 6 LR (9.2%), 10 DM (15.4%) and 5 both (7.7%). At univariate analysis, size (p = 0.03), grade (p = 0.001) and depth (p = 0.04) were associated with OS while size (p = 0.02) was associated with DFS. No significant relationship with tumour depth, type of surgery, surgical margin status or neo-/adjuvant treatment was demonstrated.Recurrence events are less common following treatment of abdominal wall sarcomas if compared to extremities STSs, but size (≥5 cm), high malignancy grade (FNCLCC 3) and depth are associated with worse OS.

BACKGROUND In extremity or trunk liposarcoma, the implications of a dedifferentiated (DD) component within a well-differentiated (WD) tumor are unclear. We evaluated outcomes after surgery and identified potential predictors of survival in these patients compared to those with an entirely WD tumor. METHODS Retrospective data were collected for patients who underwent complete resection from 2009 to 2019. Cumulative incidences of local recurrence (LR) and distant metastasis (DM) were calculated, and overall survival (OS) was estimated. Associations between OS and clinicopathologic variables were evaluated by univariable models. RESULTS A total of 210 patients with MDM2-verified tumors were studied, including 58 (27.6%) with DD. In primary disease, LR occurred only in DD and worse OS was observed versus WD (p

The outcome of patients with retroperitoneal sarcomas (RPS) depends mainly on tumor biology and completeness of surgical resection. However, some patients are deemed not resectable for various reasons. This study analyzed a series of primary RPS patients to describe rate and reasons of primary inoperability at a large referral center. All consecutive patients affected by primary localized RPS referred for surgical treatment at our institution between January 1, 2013 and December 31, 2017 were analyzed. Patients were split in two groups: those who underwent surgical resection with curative intent, and those who were not resected. A total of 322 patients were available for the current analysis: 285 (88.5%) underwent resection with curative intent, and 37 (11.5%) did not. Twenty of 322 (6.2%) patients who did not undergo resection had a technically unresectable tumor, whereas the remaining 18 of 322 (5.6%) were not amenable to a major surgical procedure due to comorbidities/poor performance status. The dominant technical reason was involvement of the celiaco-mesenteric vessels. At a median follow-up from the diagnosis of 34 months, 24 of 37 (64.9%) nonoperated and 48 of 285 (16.8%) operated patients died. The corresponding 4-year overall survival were 10.3% and 83.4%, respectively (p
