Oncological outcomes after major vascular resections for primary retroperitoneal liposarcoma.

BACKGROUND: The surgical management of retroperitoneal sarcomas frequently involves complex multivisceral resections, however retroperitoneal liposarcoma (LPS) rarely invade major abdominal vessels. The aim of the study was to assess association of major vascular resections with outcome of primary LPS. METHODS: All consecutive patients who underwent resection at our institutions for primary LPS between 2002 and 2019 were included. A propensity matched analysis was performed, adjusting the groups for the variables of Sarculator, to assess the effect of vascular resection on oncological outcomes. RESULTS: Overall 425 patients were identified. Twenty-four (5%) patients had vascular resection. At final pathology 18 patients had vascular infiltration, 2 vascular encasement and 4 involvement without infiltration. Vascular resection was associated with longer operative time (480' vs. 330'; p < 0.001) and greater need for transfusions (4 vs. 0 units; p < 0.001), and was burdened by a higher rate of major complications (54% vs. 25%; p = 0.002). After propensity matched analysis, patients undergoing vascular resection had a lower 5-year OS (60% vs. 81%; p = 0.05), and a higher incidence of local and distant recurrence at 5 years (local: 45% vs. 24%, p = 0.05; distant: 20% vs. 0%, p = 0.04). CONCLUSIONS: Vascular resection is feasible and safe even in the context of multivisceral resection for primary retroperitoneal liposarcomas, although associated to a higher complication rate. However, the independent association between vascular involvement and a higher risk of local recurrence, distant metastases and death may imply a more aggressive biology, which should be factored in the initial management of this complex disease.

Major vascular resection in retroperitoneal sarcoma surgery.

Major blood vessels may be invaded either by primary sarcomas arising from the vessel wall or by secondary infiltration of a retroperitoneal sarcoma. The involvement of major blood vessels is not considered to be an absolute contraindication for surgical resection. The main issue when evaluating a possible major vascular resection is to balance the possible surgical morbidity with the expected survival benefit. This is strictly related to the tumor's biology and clinical behavior and to the patient's performance status and comorbidities. A multidisciplinary approach in a specialized center is mandatory when approaching a possible oncovascular resection for retroperitoneal sarcoma, given the rarity and the heterogeneity of these tumors.

Subclassification of Microscopic Vascular Invasion in Hepatocellular Carcinoma.

OBJECTIVE: To investigate whether subclassification of microscopic vascular invasion (MiVI) affects the long-term outcome after curative surgical resection or liver transplantation (LT) in patients with hepatocellular carcinoma (HCC). SUMMARY OF BACKGROUND DATA: The most important factor for TNM staging in HCC is MiVI, which includes all vascular invasions detected on microscopic examination. However, there is a broad spectrum of current definitions for MiVI. METHODS: In total, 412 consecutive patients with HCC who underwent curative surgical resection without any preoperative treatment or gross vascular invasion were histologically evaluated for MiVI. Patients with MiVI were subclassified into 2 groups: microvessel invasion (MI; n = 164) only and microscopic portal vein invasion (MPVI; n = 36). Clinicopathologic features were compared between 2 groups (MI vs MPVI), whereas disease-free survival (DFS) and overall survival (OS) after resection were analyzed among 3 groups (no vascular invasion [NVI] vs MI vs MPVI). These subclassifications were validated in a cohort of 197 patients with HCC who underwent LT. RESULTS: The MPVI group showed more aggressive tumor characteristics, such as higher tumor marker levels (alpha-fetoprotein, P = 0.006; protein induced by vitamin K absence-II, P = 0.001) and poorer differentiation (P = 0.011), than the MI group. In multivariate analysis, both MI and MPVI were independent prognostic factors for DFS (P = 0.001 and <0.001, respectively) and OS (P = 0.005 and <0.001, respectively). In the validation cohort, 5-year DFS was 89%, 67.9%, and 0% in the NVI, MI, and MPVI groups, respectively (P < 0.001), whereas 5-year OS was 79.1%, 55.0%, and 15.4%, respectively (P < 0.001). CONCLUSIONS: Based on subclassification of MiVI in HCC, MPVI was associated with more aggressive clinicopathologic characteristics and poorer survival than MI only. Therefore, the original MiVI classification should be divided into MI and MPVI.

Successful emergency endovascular aortic repair for intratumoral hemorrhage in extensive retroperitoneal mass of testicular origin.

BACKGROUND: Metastatic germ cell cancer of the testis is characterized by favorable prognosis since effective treatment methods are available even in cases of extensive disease. Retroperitoneal masses frequently encroach major blood vessels requiring a vascular intervention usually performed in association with the post-chemotherapy retroperitoneal lymph node dissection (RPLND). Reported clinical case describes a successful pre-treatment endovascular surgery for abdominal aortic rupture allowing for full-dose systemic chemotherapy administration, and subsequent radical surgical intervention at primary tumor site as well as metastatic retroperitoneal lymph node dissection including the reconstruction of inferior caval vein. CASE PRESENTATION: Patient presented with left-sided testicular tumor and voluminous retroperitoneal mass with vascular involvement. Soon after the patient had been admitted for the first cycle of cisplatin-based chemotherapy, computed tomographic angiography (CTA) revealed a dorsal aortic wall rupture with active extravasation and irregular pseudoaneurysmatic dilatation of the aorta below the leak area. Retroperitoneal intratumoral hemorrhage associated with the bilateral iliac venous thrombosis required an endovascular repair procedure of infrarenal abdominal aorta. CONCLUSIONS: Following the successful endovascular aortic repair 3 cycles of BEP (bleomycin, etoposide, cisplatin) regimen were administered with subsequent delayed left radical orchiectomy and RPLND associated with vena cava inferior (VCI) resection. Reconstruction of VCI was originally not deemed necessary as collateral blood flow appeared sufficient, however, intraoperative complications resulted in the need for unilateral VCI reconstruction, using the interposed bypass between right common iliac vein and infrarenal segment of VCI. Histopathologic examination of the attained specimen detected no vital cancer structures. The patient remains disease-free 18 months after the RPLND.

Multimodality Imaging of Abdominopelvic Tumors with Venous Invasion.

A broad range of abdominal and pelvic tumors can manifest with or develop intraluminal venous invasion. Imaging features at cross-sectional modalities and contrast-enhanced US that allow differentiation of tumor extension within veins from bland thrombus include the expansile nature of tumor thrombus and attenuation and enhancement similar to those of the primary tumor. Venous invasion is a distinctive feature of hepatocellular carcinoma and renal cell carcinoma with known prognostic and treatment implications; however, this finding remains an underrecognized characteristic of multiple other malignancies-including cholangiocarcinoma, adrenocortical carcinoma, pancreatic neuroendocrine tumor, and primary venous leiomyosarcoma-and can be a feature of benign tumors such as renal angiomyolipoma and uterine leiomyomatosis. Recognition of tumor venous invasion at imaging has clinical significance and management implications for a range of abdominal and pelvic tumors. For example, portal vein invasion is a strong negative prognostic indicator in patients with hepatocellular carcinoma. In patients with rectal cancer, diagnosis of extramural venous invasion helps predict local and distant recurrence and is associated with worse survival. The authors present venous invasion by vascular distribution and organ of primary tumor origin with review of typical imaging features. Common pitfalls and mimics of neoplastic thrombus, including artifacts and anatomic variants, are described to help differentiate these findings from tumor in vein. By accurately diagnosing tumor venous invasion, especially in tumors where its presence may not be a typical feature, radiologists can help referring clinicians develop the best treatment strategies for their patients. ©RSNA, 2020.

Rare case of hepatocellular carcinoma metastasising to the pituitary and cavernous sinus causing panhypopituitarism and bilateral ophthalmoplegia.

Pituitary metastases, especially from a primary hepatocellular carcinoma (HCC), are rare. Review of the literature revealed only few cases reporting pituitary metastases complicated by panhypopituitarism from HCC. Calvarial metastases from HCC are even more rare. Here, we present a unique case of primary HCC with metastases to both the calvarium and the pituitary causing panhypopituitarism and bilateral ophthalmoplegia, respectively. To our knowledge, this is the first reported case of two unique and rare complications from metastatic HCC.

Surgical Tips for Inferior Vena Cava Thrombectomy.

PURPOSE OF REVIEW: The aim of this review is to describe the preoperative evaluation, surgical techniques, and postoperative management of patients with renal cell carcinoma (RCC) undergoing radical nephrectomy (RN) and inferior vena cava (IVC) thrombectomy. RECENT FINDINGS: RN and IVC thrombectomy remains the standard management option in non-metastatic RCC patients with IVC thrombus. A comprehensive preoperative workup, including high-quality imaging, blood works, and appropriate consultations are required for all patients. The aim of the surgery is complete resection of all tumor burden, which requires a skillful surgical team for such a challenging procedure and is inherently associated with a high rate of perioperative morbidity and mortality. Preoperative CT or MRI is essential for surgical planning. The surgical approach is mainly determined by the level of the tumor thrombus. The open approach has been the standard, though minimally invasive and robotic techniques are emerging in selected cases by experienced surgeons.

The authors reported a rare clinical case of successful surgical treatment of young female with retroperitoneal leiomyosarcoma followed by lesion of the cavarenal segment of inferior vena cava, left renal vein. Clinical and morphological features of disease, postoperative outcomes and prognostic factors in patients with retroperitoneal leiomyosarcoma are discussed.

Extended thymectomy with blood vessel resection and reconstruction improves therapeutic outcome for clinical stage III thymic carcinoma patients: a real-world research.

OBJECTIVES: We examine the therapeutic efficacy of extended thymectomy with blood vessel resection and reconstruction in thymic carcinoma patients with great vessel invasion. METHODS: In total 26 patients diagnosed as clinical stage III thymic carcinoma with severe great vessel invasion were enrolled in this retrospective study. Among these patients, 14 cases received adjuvant chemo- and radiotherapy (non-operation subgroup, NOG), the other 12 patients received extended thymectomy with vessel resection and reconstruction followed by the adjuvant treatment (operation subgroup, OG). RESULTS: All surgical procedures went smoothly with no perioperative death. R0 resection was obtained in all surgical cases, and we also observed a lymph node metastasis rate of 38.8%. The overall survival (OS) was 34 months for the whole cohort, 48 and 26 months for the OG and NOG respectively (p = 0.013). The median disease metastasis free survival (DMFS) was 47 months for the OG and 18 months for the NOG (p = 0.019). CONCLUSION: Extended thymectomy with vessel resection is feasible for patients with clinical stage III thymic carcinoma. Surgery significantly improves the overall survival and the prognosis of clinical stage III thymic carcinoma.

Laparoscopic conversion to open surgery in radical nephrectomy and tumor thrombectomy: causal analysis, clinical characteristics, and treatment strategies.

BACKGROUND: We aimed to explore the causal analysis, clinical characteristics and treatment strategies of laparoscopic conversion to open approach (LCTOA) in radical nephrectomy and tumor thrombectomy. METHODS: We included all patients with Mayo level I-III renal tumors with inferior vena cava (IVC) tumor thrombus who underwent laparoscopic radical nephrectomy and tumor thrombectomy as the first choice from May 2015 to July 2019. RESULTS: There were 70 cases of renal tumor with IVC tumor thrombus treated with a laparoscopic approach as the first choice; 31 Mayo level I, 30 Mayo level II, and 9 Mayo level III. A completely laparoscopic approach was performed in 51 cases (72.9%), and 19 cases (27.1%) underwent active or passive LCTOA. The LCTOA group had higher median preoperative serum creatinine (110.0 µmol/L vs 92.0 µmol/L; P = 0.026), longer postoperative hospital stay (9 days vs 7 days; P = 0.008), longer median operation time (374 min vs 311 min; P = 0.017), higher median intraoperative hemorrhage volume (1300 vs 600 ml; P = 0.020), and higher proportion of male patients (94.7% vs 66.7%; P = 0.016) vs the completely laparoscopic group, respectively. Although preoperative serum creatinine and gender were risk factors in the univariate analysis, multivariate analysis revealed no independent risk factors for LCTOA. We divided the reasons for LCTOA into active conversion and passive conversion; 4 (21.1%) cases underwent active conversion, and 15 (78.9%) underwent passive conversion. Most of the patients undergoing passive conversion had multiple concurrent risk factors, among which perirenal adhesion (30.9%), organ invasion (16.4%), and IVC adhesion (25.5%) were the most common. Fourteen (73.7%) cases underwent renal treatment, and 5 (26.3%) cases underwent tumor thrombus treatment. CONCLUSIONS: The LCTOA group had a higher median preoperative serum creatinine concentration, longer hospital stay, longer median operation time, and higher median intraoperative hemorrhage volume. However, none of the predictors in our study was an independent risk factor for LCTOA. Perirenal adhesion, organ invasion, and IVC adhesion were the most common causes of LCTOA. Considering the limitations of this study, studies with large sample sizes are required to validate our conclusions.

2D and 3D texture analysis to predict lymphovascular invasion in lung adenocarcinoma.

PURPOSE: Lymphovascular invasion (LVI) impairs surgical outcomes in lung adenocarcinoma (LAC) patients. Preoperative prediction of LVI is challenging by using traditional clinical and imaging factors. The purpose of this study was to evaluate the value of two-dimensional (2D) and three-dimensional (3D) CT texture analysis (CTTA) in predicting LVI in LAC. METHODS: A total of 149 LAC patients (50 LVI-present LACs and 99 LVI-absent LACs) were retrospectively enrolled. Clinical data and CT findings were analyzed to select independent clinical predictors. Texture features were extracted from 2D and 3D regions of interest (ROI) in 1.25 mm slice CT images. The 2D and 3D CTTA signatures were constructed with the least absolute shrinkage and selection operator algorithm and texture scores were calculated. The optimized CTTA signature was selected by comparing the predicting efficacy and clinical usefulness of 2D and 3D CTTA signatures. A CTTA nomogram was developed by integrating the optimized CTTA signature and clinical predictors, and its calibration, discrimination and clinical usefulness were evaluated. RESULTS: Maximum diametre and spiculation were independent clinical predictors. 1125 texture features were extracted from 2D and 3D ROIs and reduced to 11 features to build 2D and 3D CTTA signatures. There was significant difference (P < 0.001) in AUC (area under the curve) between 2D signature (AUC, 0.938) and 3D signature (AUC, 0.753) in the training set. There was no significant difference (P = 0.056) in AUC between 2D signature (AUC, 0.856) and 3D signature (AUC, 0.701) in the test set. Decision curve analysis showed the 2D signature outperformed the 3D signature in terms of clinical usefulness. The 2D CTTA nomogram (AUC, 0.938 and 0.861, in the training and test sets), which incorporated the 2D signature and clinical predictors, showed a similar discrimination capability (P = 1.000 and 0.430, in the training and test sets) and clinical usefulness as the 2D signature, and outperformed the clinical model (AUC, 0.678 and 0.776, in the training and test sets). CONCLUSIONS: 2D CTTA signature performs better than 3D CTTA signature. The 2D CTTA nomogram with the 2D signature and clinical predictors incorporated provides the similar performance as the 2D signature for individual LVI prediction in LAC.

Ectopic hepatocellular carcinoma in the adrenal gland with inferior vena cava thrombosis and right atrial extension.

Intravascular tumor extension in the inferior vena cava (IVC) is known to occur with abdominal tumors, such as renal cell, hepatocellular, adrenal cell carcinoma, and Wilm's tumor. We encountered a 53-year-old male patient presenting with pulmonary embolism and a right atrial mass with imaging evidence of an adrenal tumor extending into the IVC, up to the right atrium. The patient underwent surgery for the resection of the tumor using cardiopulmonary bypass by a team of cardiothoracic surgeons and urologists. Histology identified the tumor as hepatocellular carcinoma, which developed as ectopic hepatic tissue in the right adrenal gland.

Sinusoidal hemangioma with secondary intravascular papillary endothelial hyperplasia.

In this case report, we present a case of a 47-year-old man with sinusoidal hemangioma with secondary intravascular papillary endothelial hyperplasia arising in the subcutaneous tissue. To the best of our knowledge, there are only two cases of sinusoidal hemangioma with secondary intravascular papillary endothelial hyperplasia reported till date, both of which were intramuscular hemangiomas. These are rare entities that also have overlapping histomorphological features with that of various other vascular tumors making histopathological diagnosis troublesome at times. Careful histopathological examination aided by immunohistochemical studies in difficult cases is essential to avoid these diagnostic pitfalls.

Real world clinical practice in treating advanced hepatocellular carcinoma: When East meets West.

BACKGROUND AND AIMS: The Barcelona Clinic Liver Cancer (BCLC) stage C (BCLC C) of hepatocellular carcinoma (HCC) includes a heterogeneous population for which sorafeninb is one of the recommended therapies. We aim to evaluate the real world clinical treatment and survival of BCLC stage C patients in an Asian cohort. METHODS: This is a retrospective cohort study that enrolled 427 consecutive BCLC stage C patients diagnosed between 2011 and 2017 by using the HCC registry data for our hospital. All patients were managed via a multidisciplinary team (MDT) approach. RESULTS: Hepatitis B surface antigen positive was noted in 50.6% of the patients. The patients were classified as performance status (PS)1 alone (n = 83; 19.4%), PS2 alone (n = 23; 5.4%), or macrovascular invasion (MVI) or extrahepatic spread (EHS) (n = 321; 75.2%). The median overall survival (OS) was 11.0 months in the whole cohort. The most frequent treatments were transcatheter arterial embolization (TAE) in the PS1 (45.8%) and PS2 patients (52.2%) and sorafenib (32.4%) in the MVI or EHS patients. The independent prognostic factors were the PS, Child-Pugh class, MVI or EHS, alpha fetoprotein levels, and treatment type. CONCLUSIONS: We reported the real world management in BCLC stage C patients in an Asian cohort through the use of personalized management via a MDT approach.

Adjuvant chemotherapy improves overall survival in patients with localized upper tract urothelial carcinoma harboring pathologic vascular invasion: a propensity score-matched analysis of multi-institutional cohort.

OBJECTIVE: Whether adjuvant chemotherapy (AC) for patients with upper tract urothelial carcinoma (UTUC) offers survival benefit is still controversial. To explore the impact of AC on overall survival (OS) of cN0M0 UTUC patients, we conducted a propensity score-matched analysis using the regression model, including pathologic features such as lymphatic and vascular invasion. METHODS: A multi-institutional cohort of 413 UTUC patient record was used. Propensity score matching was performed to reduce bias by potential confounding factors for survival, including pathologic features from the specimen of radical nephroureterectomy (RNU), RESULTS: Ninety-eight patients were identified as pair-matched groups (49 patients in RNU and 49 patients in RNU + AC). Kaplan-Meier curves demonstrated that a 5-year OS rate of 72.7% for patients treated with RNU + AC was significantly higher than 51.6% for those treated with RNU (p = 0.0156). On multivariate analysis, pathologic vascular invasion (HR 3.41, 95% CI 1.24-10.66, p = 0.0166) and administration of AC (HR 0.45, 95% CI 0.19-0.98, p = 0.0438) still remained as the significant predictors for OS. In patients with pathologic vascular invasion (51 of 98 patients), a significantly longer OS in RNU + AC groups was observed (median OS of 30 and 70 months in RNU and RNU + AC groups, respectively: p = 0.0432), whereas there was no significant difference in the OS between RNU (median OS: not reached) and RNU + AC (median OS: not reached) groups in patients without the invasion (p = 0.4549). CONCLUSION: The result indicates a significant benefit for OS by the administration of AC, and pathologic vascular invasion in the specimen of RNU could help the patient selection to better predict the effect of AC.

Hepatocellular carcinoma with inferior vena cava and right atrial tumor thrombus: A case report.

This is a case report of a 45-year-old patient admitted with the symptom of bilateral leg swelling. Ultrasonography revealed a hyperechoic mass in the right lobe of the liver, which invaded the right hepatic vein (RHV) and extended into the inferior vena cava (IVC) and right atrium (RA). Based on the high alpha-fetoprotein (AFP) level and the ultrasonography findings, the patient was diagnosed as having hepatocellular carcinoma (HCC) with a RHV, IVC, and RA tumor thrombus and secondary Budd-Chiari syndrome (BCS). HCC with a tumor thrombus extending into the IVC and RA has rarely been observed, and as a cause of secondary BCS, this type of HCC has been even more rarely reported.

Case report: recurrent metastatic breast cancer in internal mammary dissection bed discovered at the time of coronary bypass.

INTRODUCTION: Many patients who undergo coronary artery bypass surgery have a prior history of cancer and potentially chest radiation which is a known risk factor for coronary atherosclerosis. Prior radiation increases fibrosis and can make the dissection of the left internal mammary artery (LIMA) more challenging. CASE REPORT: A 72-year-old woman with a history of stage IIA pT2N0M0 left breast intraductal carcinoma treated with lumpectomy, adjuvant chemotherapy and radiation therapy 11 years prior presented to the emergency room with a non-ST elevation myocardial infarction and was taken for cardiac catheterization followed by three-vessel coronary artery bypass grafting. The LIMA was found to be encased in scar tissue and was deemed unsuitable as a conduit, and a saphenous vein graft was bypassed to the left anterior descending artery in its place. Pathologic review of the LIMA showed nests of tumor cells infiltrating within dense fibrous tissue with areas of necrosis and calcifications consistent with recurrent breast cancer. Interestingly the patients original breast cancer was positive for estrogen receptors (ER) and progesterone receptors (PR) ER and PR and negative for HER2 and she had therefore been treated with 5 years of hormonal therapy. The recurrent cancer found in the LIMA dissection bed at the time of bypass surgery was ER, PR, and HER2 negative, suggesting hormonal therapy driven clonal selection of these metastatic tumor cells. DISCUSSION AND CONCLUSIONS: Scarring in the LIMA dissection bed in patients with a history of cancer and prior chest radiation should be carefully evaluated for the possibility of recurrent cancer. The gross appearance of tissue can be misleading and sending a biopsy for a formal frozen section histologic evaluation should be considered if there is any question of recurrent malignancy.

The value of combined vein resection in pancreaticoduodenectomy for pancreatic head carcinoma: a meta-analysis.

BACKGROUND: Although pancreaticoduodenectomy with vein resection (PDVR) is widely performed in selected patients with indications, its benefits remain controversial. In this meta-analysis, we evaluate the safety and efficacy of PDVR in comparison to standard pancreaticoduodenectomy (PD). METHODS: We searched PubMed, Embase, and Cochrane as well as the Chinese National Knowledge Infrastructure, Weipu, and Wanfang databases for studies that evaluate the value of PVDR. The data of the patients who underwent PD or PDVR were analyzed using Review Manager and STATA software. RESULTS: In comparison with the PD group, the PDVR group had a lower R0 resection rate and higher rates of complications such as biliary fistula, reoperation rate, delayed gastric emptying, cardiopulmonary abnormalities, hemorrhage, in-hospital mortality, 30-day mortality. The blood loss, duration of operation, total hospital stay is higher in PDVR group. CONCLUSIONS: Compared to standard PD, PDVR was associated with a greater risk of some specific complications and increase the mortality rate, total hospital stay time, combine with vein resection have a lower R0 resection rate. Therefore, combine with vascular resection for pancreatic cancer needs to be carefully selected by the surgeon.

[Local, regional and systemic dissemination of choroidal melanoma : Clinical and pathological correlation from 2 cases]. / Dissémination locorégionale et systémique du mélanome choroïdien : corrélation anatomoclinique à partir de 2 cas.

PURPOSE: To describe didactically the local, regional and systemic spread of choroidal melanoma. PATIENTS AND METHODS: Two patients who had undergone primary enucleation for the management of choroidal melanoma in 2018 at the University Hospital of Nice were included. Extrascleral extension and invasion of the vortex veins were evaluated, as well as synchronous and metachronous metastases, based on our database. RESULTS: Patient 1 was diagnosed with large choroidal melanoma with partial scleral invasion and vortex vein involvement. Cytogenetic analysis demonstrated a loss of chromosome 3, and a gain of chromosome 8q. Systemic work-up was unremarkable. Patient 2 was diagnosed with a large choroidal melanoma with extrascleral extension and vortex vein involvement. Cytogenetic analysis demonstrated a loss of chromosome 3 and a gain of chromosome 8q. Systemic work-up revealed several liver metastases. A total of 1762 patients were included in our database. Eighty-five patients (4.8 %) and 46 patients (2.6 %) experienced vortex vein invasion and extrascleral extension respectively. Patients with vortex vein invasion were diagnosed with synchronous and metachronous liver metastases in 1.2 % and 18.8 % respectively. Patients with extrascleral extension had synchronous and metachronous liver metastases in 6.5 % and 30.4 % respectively. The mean follow-up was 49.4 months (1-180). CONCLUSION: Extrascleral extension and vortex vein invasion illustrate the local, regional and systemic spread of choroidal melanoma. The latter are often associated with genetically aggressive tumours associated with high metastatic risk.
