Intravascular papillary endothelial hyperplasia (IPEH), also known as Masson tumor, is a rare vascular benign tumor of blood vessels. It may occur in any part of the body, especially the deep dermis and subcutaneous tissue of the head, neck, fingers and trunk. The imaging and histopathology of IPEH are similar to hemangiosarcoma, especially in the case of active vascular endothelial hyperplasia. IPEH is a reactive proliferative lesion of vascular intima. The etiology is still unclear. After some studies showed that IPEH was a benign lesion, few reports on the etiology of it were reported. IPEH is usually limited to the thrombotic vessels or lumens of vascular malformations, usually accompanied by a clear history of trauma. IPEH usually does not cause any symptoms. It looks like a slow-growing lump. Some cases have been reported with pain and swelling. Although IPEH is relatively rare, its accurate diagnosis is crucial because it may be similar to malignant angiogenic lesions in clinical practice. There were few reports of cases related to intravascular papillary endothelial hyperplasia located in the sternocleidomastoid muscle after reviewing the domestic and foreign literature in recent 10 years. This case reports that a young male, who was admitted to the hospital one month after finding a subcutaneous tumor in the left neck. After admittance, relevant preoperative examinations were completed. After multi-disciplinary discussion and elimination of surgical contraindications, a specific surgical plan was formulated. The tumor was removed under local anesthesia on the second day after admission. During the operation, it was found that the tumor was located between the sternocleidomastoid muscle bundles, and it was sent for pathologic examination. Paraffin section pathology was reported after operation. Histological examination showed that the morphology was consistent with vascular endothelial papillary hyperplasia. There were no related surgical complications and recurrence in the 3-month follow-up. The purpose of this paper is to provide clinicians with a certain understanding of this rare disease through the report of this case of IPEH, and to identify it in later clinical work, and at the same time, to avoid confusion with malignant diseases, such as hemangiosarcoma, leading to unnecessary treatment and increase the cost of treatment.

OBJECTIVETo explore the risk factors of vascular invasion in patients with early gastric cancer (EGC), and to investigate the influence of vascular invasion on the prognosis of EGC patients.

METHODSFrom January 2014 to December 2015, 449 EGC patients underwent curative gastrectomy at the First Affiliated Hospital of Anhui Medical University, of whom 27 cases (6.0%) developed vascular invasion. Clinicopathological and follow-up data of EGC cases were analyzed retrospectively. The association between clinicopathological features and vascular invasion was analyzed by using the Chi-square test or Fisher exact test, and the independent risk factors influencing vascular invasion were identified with logistic regression. The influence of vascular invasion on overall survival was investigated with Kaplan-Meier curve. This study was approved by Ethics Committee of The First Affiliated Hospital of Anhui Medical University (No. 2018-03-12).

RESULTSOf 449 EGC patients, 325 were males and 124 were females (ratio 2.6:1.0) with the mean age of (60.8±10.5) (27 to 87) years; 228 were diagnosed as T1a stage and 221 were diagnosed as T1b. Univariate analysis showed that incidence of vascular invasion in EGC patients with ulceration or scar was 8.4%(18/225), which was higher than 3.8%(9/234) in those without ulceration, and the difference was statistically significant (χ²=4.061, P=0.044). The incidence of vascular invasion in patients with low differentiated tumor was 8.8% (20/226), which was significantly higher than 3.1%(7/223) in those with middle-high differentiated tumor(χ²= 8.363, P=0.012). The incidence of vascular invasion in patients staging T1b was 10.9% (24/221), which was significantly higher than 1.3% (3/228) in those staging T1a (P=0.000); The incidence of vascular invasion in patients with lymph node metastasis was 27.3% (15/55), which was significantly higher than 3.0%(12/394) in those without lymph node metastasis (χ²=50.122, P=0.000). However, there were no significant associations of vascular invasion with gender, age, surgical type, multiple tumor, tumor deposit, tumor location and tumor size (all P > 0.05). Multivariate analysis showed that T1b stage (RR=4.653, 95%CI:1.293-16.747, P=0.019) and lymph node metastasis(RR=7.302, 95%CI: 3.063-17.408, P=0.000) were independent risk factors for vascular invasion in EGC patients. Among 449 EGC patients, 444 received complete follow-up(98.9%), including 26 cases with vascular invasion and 418 cases without vascular invasion. The overall survival in vascular invasion group was significantly lower than that in non-vascular invasion group (χ²=60.463, P=0.000). Besides, 198 EGC patients gained follow-up for 3 years, and the 3-year survival rates of 11 vascular invasion cases and 187 non-vascular invasion cases were 54.5% and 96.8% respectively.

CONCLUSIONSThe risk of vascular invasion is higher in EGC patients with lymph node metastasis and tumor infiltrating the submucosa. The prognosis of EGC patients with vascular invasion is poor.

BACKGROUNDAngiogenesis is the formation of new blood vessels to supply nutrients to tumors. Vascular endothelial growth factor (VEGF) and cluster of differentiation 34 (CD34) are important signaling proteins involved in angiogenesis. Many studies have demonstrated that VEGF and CD34 are related to tumor progression. This study focused on the relationship between VEGF, CD34, and perioperative hemorrhage in patients with gastric cancer.

METHODSTo observe the relationship between VEGF and CD34, we tracked 112 patients with advanced gastric cancer for 5 years to assess factors related to hemorrhage, using immunohistochemistry. The results were subjected to statistical analysis using a 2 × 2 contingency table, logistic regression, and receiver operating characteristic (ROC) test.

RESULTSThe concentrations of VEGF and CD34 were critically correlated with perioperative hemorrhage and neural invasion in patients with gastric cancer (P < 0.05). Expression of VEGF and CD34 was related (P < 0.05, χ2 = 6.834). VEGF and CD34 co-expression strongly increased the risk of preoperative bleeding (area under the ROC curve >0.7, P < 0.05).

CONCLUSIONSExpression of VEGF and CD34 was critically correlated with perioperative hemorrhage in gastric cancer patients. Co-expression of VEGF and CD34 could be an effective indicator for evaluating the risk of perioperative bleeding in gastric cancer patients.

Objective To investigate the diagnosis and surgical treatment strategies of intravenous leiomyomatosis(IVL)extending through inferior vena cava into the right cardiac cavities. Methods Thirty patients of IVL extending through inferior vena cava into the right cardiac cavities were treated in Peking Union Medical College Hospital from November 2002 to January 2015.The following variables were studied: age,cardiopulmonary bypass time,deep hypothermic circulatory arrest time,origins of IVL,blood loss,duration of post-operative hospital stay,hospitalization expenses,edema of lower extremity,blood transfusion,postoperative complication,residual IVL,and re-grow or recurrence. Results Thirteen of 30 patients reported double lower limb edema. The cardiopulmonary bypass was applied in 27 cases,and the average duration of cardiopulmonary bypass was(106.9±53.7)min. Then,21 patients were treated with the deep hypothermic circulatory arrest,and the mean time was(28.2±11.6) min. The tumors originated from the genital veins in 9 cases,the iliac vein in 13 cases,and both veins in 8 cases. The average intra-operative blood loss volume was (2060.5±2012.3)ml,and 21 patients received blood transfusion. The average hospitalization time was(18.9±8.3)days and the average hospitalization expenses was (80 840.4±28 264.2)RMB yuan. While 14 patients had postoperative complications,there was no serious postoperative complication or death.All patients have shown a favorable outcome.Conclusions Tumor embolus extending through inferior vena cava into the right cardiac cavities should be suspected in patients with multiple hysteromyoma. Successful therapy for IVL with right cardiac cavities extension is dependent on reasonable surgical treatment strategies. Surgical removal of the ovaries is vital to avoid IVL re-grow or recurrence.

OBJECTIVETo study the treatment strategy and survival of patients with primary leiomyosarcoma of inferior vena cava (PIVCLMS).

METHODSClinical data of 12 cases with PIVCLMS admitted in Peking University People's Hospital from January 2006 to September 2014 were reviewed retrospectively. All cases were confirmed by pathology examination. Among them, there were 4 male and 8 female patients with a mean age of (54 ± 9) years old. Tumors arose from the inferior vena cava (IVC) upper segment in 5 patients, from the middle in other 7 patients. Cardiac extension was observed in 4 cases. Tumor resection was undertaken in 8 patients, the other 4 patients were inoperable. The series was analyzed to identify clinical outcome of surgical strategy and protective factors for patient survival.

RESULTSIn tumor resection group, 6 patients had radical resection and 2 underwent palliative resection. As for IVC reconstruction, caval wall resection with a direct suture was carried out in 6 patients or with prosthetic patch in 1 patient. The other 1 patient underwent a segment caval resection and prosthetic graft replacement in situ. In 4 cases of suprahepatic PIVCLMS cardiopulmonary bypass or perfusion by right atrial intubation was performed to assist bleeding control and maintain circulation stabilization, among them 1 patient survived for more than 101 months with no tumor recurrence or metastasis. Among the patients submitted to tumor resection 2 early postoperative deaths occurred, and another 2 patients had complications. All 4 patients submitted to non-resective operation (only neoplasm biopsy) died of PIVCLMS within 8 months. Except for 2 cases of early death, mean survival after tumor resection was (54 ± 40) months. Two patients presented local recurrence and hepatic metastasis at follow-up of 16 months and 68 months.

CONCLUSIONSTumor resection is the only therapy for PIVCLMS with an expectation for long-term survival. The applicant of cardiopulmonary bypass makes some inoperable indicated to tumor resection.

Integrated resection of the pancreatic head is the most difficult step in radical pancreaticoduodenectomy (RPD) in patients with the portal vein (PV) and superior mesenteric vein (SMV) invasion or oppression by the tumor. This study introduced a new idea and skill named the "total arterial devascularization first" (TADF) technique and its applications in RPD. Three arterial blood supplies of pancreatic head were obstructed before dissection of veins. The critical steps included exposure of the anterior surface of the abdominal aorta (AA) by completely transecting neural and connective tissue between superior mesenteric artery (SMA) and pancreatic mesounsinate, and transection of the mesounsinate from the origin of SMA to the root of the celiac trunk. From January 2012 through May 2013, a total of 58 patients with PV/SMV invasion or oppression underwent RPD using this technique. The median operative time was 5.1 h (ranging 4.5-8.1 h). The median intraoperative blood loss was 450 mL (ranging 200-900 mL). No intraoperative and postoperative bleeding of pancreatic head region occurred. Among the 58 patients, 21 were subjected to vessel lateral wall angiectomy or angiorrhaphy, and 10 to angiectomy and end-to-end anastomosis. The incidence of postoperative bleeding, postoperative pancreatic fistula and biliary fistula was 5.2%, 6.8%, and 1.7%, respectively. No patients died 3 months after operation. The TADF technique is a new method for intricate RPD and could improve the security of surgery and reduce intraoperative bleeding, which is expected to become standardized surgical approach for RPD.

OBJECTIVETo investigate the correlation of baseline plasma D-dimer levels and clinicopathological features and tumor VEGF expression in non-small cell lung cancer(NSCLC) patients, and to evaluate the value of D-dimer in predicting survival time.

METHODSA retrospective review of the clinicopathological data of 290 NSCLC patients confirmed pathologically in Tianjin Cancer Hospital from July 2007 to April 2009 was performed. The correlations between plasma baseline D-dimer levels and clinicopathological characteristics and progonosis were analyzed.

RESULTSFor 290 NSCLC patients with low ( ≤ 0.3 µg/ml) and high (>0.3 µg/ml) D-dimer levels, the median survival times were 54.0 months and 46.2 months, respectively (P < 0.05), and for the patients with stages I, II, IIIA, IIIB and IV NSCLC, the median survival times were 58.1, 40.6, 26.7 and 23.5 months, respectively (P < 0.05). In the operable patients (stages I, II and IIIa) with low and high D-dimer levels, the median progression-free survivals (PFS) were 35.0 and 11.0 months, respectively (P < 0.05). Furthermore, the median PFSs were 57.2 months and 19.6 months, respectively, in these operable patients without and with lymph node metastasis (P < 0.05).

CONCLUSIONSHigh levels of baseline plasma D-dimer may indicate advanced disease stage, larger tumor size, lymph node metastasis and stronger tumor angiongenesis to some extent, and may be useful in prediction of survival time in NSCLC patients of different stages.

Recently, we treated a patient with pulmonary vein sarcoma. The patient was a 41-year-old woman, had cough, short of breath and apsychia, with obvious jugular venous distention, rales in both lungs and a diastolic murmur at the apex. CT and Echo revealed a tumor in the left atrium. She received an emergency surgery to remove the mass in the heart. The pathological diagnosis demonstrated it as leiomyosarcoma. Though the patient accepted radiotherapy and chemotherapy, she still died of recurrence and metastasis of the sarcoma 10 months after operation.
