Leiomyosarcoma is a rare tumor that originates in the smooth muscle, usually in the gastrointestinal tract, the retroperitoneum and the genitourinary tract. The omentum has been rarely reported as a primary site of occurrence with leiomyosarcoma. A 72 year-old woman, with palpable mass on the left upper quadrant of abdomen and weight loss, was admitted to St. Paul's Hospital. Abdominal CT scan showed a 12 x 8 x 8 cm-sized cystic mass in the left upper quadrant of the abdomen. Endoscopic ultrasonography showed a large cystic mass between the stomach and the liver, which was 1.6 cm length in wall thickness. Laparotomy and resection of the mass was performed. A 12 x 8 x 8 cm-sized mass, originated from the lesser omentum, was discovered near the lesser curvature of the stomach. Microscopic examination revealed spindle-shaped cells with 7-8 mitoses per high power field. She was diagnosed as primary leiomyosarcoma originated from the lesser omentum.

OBJECTIVETo investigate the clinicopathological characteristics and prognostic factors in patients with intra-abdomen extragastrointestinal stromal tumors (EGISTs).
METHODSThe data of 47 patients of mesenchymal neoplasms that arose from the abdominal cavity and retroperitoneum, collected from July 1987 to June 2003 in our hospital with complete clinical and pathological data, were investigated retrospectively. EGISTs were diagnosed by reviewing the tumor slides stained with hematoxylin and eosin (H&E). Immunohistochemistry staining were performed on CD117, CD34, smooth muscle actin, Desmin and S-100 proteins. The relations of various clinicopathologic characteristics and outcomes were examined.
RESULTSAmong the 47 cases, 30 tumors were confirmed to be EGISTs. Twelve cases arose from the mesentery, six from small omentum, eight from retroperitoneum and four from the abdominal cavity. The size of tumors ranged from 4 to 30 cm (median 12.5 cm) in diameter and the tumor cell components mainly included spindle cells (23 cases), epithelioid cells (4 cases), and mixed cells (3 cases). The follow-up rate was 90% and the median follow up time was 44 months. The patient survival rates at 1, 5 and 10 years were 79.7%, 59.5% and 45.4% respectively. Univariate analysis showed that tumor size >10 cm, tumor necrosis, mitoses > or =5/50HPF, obvious nuclear atypia, moderate and poor differentiated tumor cells were predictors of poor prognosis.
CONCLUSIONSEGISTs have specific clinical behaviors. The parameters used for predicting GISTs prognosis are not completely applicable for EGISTs. Tumor necrosis, obvious nuclear atypia and mitoses > or =5/50HPF help to predict aggressive behaviors in EGISTs.

6.Chinese expert consensus on the diagnosis and treatment of peritoneal metastasis of gastric cancer (2023 edition).
Chinese Journal of Gastrointestinal Surgery 2023;26(8):717-728
China is a country with a high incidence of gastric cancer, and the majority of patients are in the advanced stage. The peritoneum is the most common site of metastasis and recurrence in advanced gastric cancer. Attention to the standardized diagnosis and treatment of peritoneal metastases of gastric cancer is expected to significantly improve the prognosis and quality of life of some patients. Based on evidence-based medicine and the internationally accepted Delphi method, this consensus revises the Chinese expert consensus on the prevention and treatment of peritoneal metastasis of gastric cancer (2017 edition), reaches a preliminary consensus on the definition, classification, risk factors, diagnosis and prediction, grade assessment, prevention, treatment and management of complications of peritoneal metastasis of gastric cancer, and provides guidance for clinical work.

9.Epididymal liposarcoma with metastases to the retroperitoneal space and peritoneal cavity: A case report and literature review.
National Journal of Andrology 2017;23(12):1103-1106
Objective:
To report a rare case of epididymal liposarcoma with multiple metastases to the retroperitoneal space and peritoneal cavity for the purpose of improving the diagnosis and treatment of the disease.
METHODS:
We retrospectively analyzed the clinical data about a case of epididymal liposarcoma with multiple metastases to the retroperitoneal space and peritoneal cavity, reviewed relevant literature at home and abroad, and investigated the presentation, diagnosis and treatment of the disease.
RESULTS:
A 47-year-old male patient with epididymal liposarcoma underwent radical left orchiectomy with high ligation of the spermmatic cord. Ten years later, recurrence and metastasis were observed in the retroperitoneal space with a mass of 15.6 × 9.4 × 25.5 cm occupying an area from the upper pole of the left kidney to the pelvic cavity and enclosing the left kidney and upper ureter, for which the patient received radical resection of the retroperitoneal tumor. However, multiple retroperitoneal and intraperitoneal metastases occurred again 4 years later, which was treated by another surgical resection. The patient died of lung failure a year later.
CONCLUSIONS
Epididymal liposarcoma is a rare entity, which can be diagnosed by careful clinical and radiological examinations and confirmed by pathology. For its treatment, radical inguinal orchiectomy should be performed as early as possible, but the roles of adjuvant radiotherapy and chemotherapy remain controversial. Given the high rate of recurrence and metastasis, long-term follow-up is necessitated for the patient postoperatively.
