ABSTRACT
Objective To explore the diagnosis,treatment and prognosis of primary gastric malignant (lymphoma)(PGML).Methods The diagnosis and treatment data of 21 cases of PGML admitted in our(hospital) during 8 years was retrospectively analyzed.The diagnostic methods included barium meal(examination),gastroscopy,B type ultrasonography,and CT scan.All patients underwent operative treatment and most of the patients received adjuvant chemotherapy.Results Upper abdominal pain,digestive tract bleeding,emaciation and abdominal mass were common clinical manifestations of PGML.The resectabilty rate of PGML was 90.5% while the 5-year survival rate was 57.1%.Conclusions The key to a satisfactory prognosis was early diagnosis,radical curative operation and combined treatment.
ABSTRACT
Objective To establish a more sensitive method to detect free cancer cells in peritoneal washings of gastric cancer cases during surgery. Methods The CEAmRNA levels in peritoneal washings in 65 cases of gastric cancer were detected by Real-time RT-PCR. PLC was applied simultaneously to detect free cancer cells. Negative controls included the peritoneal washings from 5 cases of benign gastric diseases and the blood samples from 5 cases of healthy adult volunteers. Results (1)CEAmRNA was not found in peritoneal washings in benign gastric diseases and in blood of healthy adult volunteers. (2)The positive percentage of free cancer cells detected by Real-time RT-PCR was 47.7%, while PLC′s was only 12.3%.(3)The positive rate of CEAmRNA showed a significant difference between gastric cancer with serosal invasion and without serosa invasion groups, between peritoneal metastasis group and no peritoneal metastasis groups, and also between stages I+II and III+IV diseases(all P
ABSTRACT
Objective To study the diagnosis and treatment of gastric stromal tumor(GST). Methods The clinical manifestation,pathological features ,diagnosis and treatment of 14 patients with GST were retrospectively analysed . Results Of the 14 GST,7 located in the fundus and the body of the stomach, 7 in the antrum of the stomach. The main symptom was abdominal pain, All the 14 GST were diagnosed by endoscopey, barium, ultrasound and CT. All patients were treated by excision. Histological diagnosis was as benign tumor in 8(57.1%)cases, uncertain types in 5 (35.7%)cases , and malignant tumor in 1 ( 7.1 %)case. There were local recurrence in 3 cases and death in 1 case after the operation. Conclusions The complete local excision is recommended for GST patients. Long term postoperative follow up is necessary for patients with GST. Reexcision may be helpful to the patients with recurrence or metastasis.
ABSTRACT
Objective To explore the value of CT in the preoperative assessment of resectability of advanced gastric carcinoma.Methods The relation of CT findings and operative data in 93 cases of advanced gastric carcinoma were retrospectively analyzed.Results There were 23 cases of fundus and cardia carcinoma,59 cases of carcinoma of gastric corpus,and 11 cases of carcinoma of antrum.All cases showed increased thickness of gastric wall in various degrees,some of the cases showed tumor growth in the gastric wall,ulcer of the mucosa,stricture of gastric cavity and cardia,increased thickness of cardiac wall,and invasion of lower esophagus and perigastric organs.The accuracy of location and definitive diagnosis by CT,compared to gastroscopic biopsy and postoperative pathology,was considerable,and the detecting rate of tumor by CT was 100 %.CT had important reference value in preoperative evaluation of tumor resectability.The excision rate in the predicted operable group was 93.3 %;in the predicted unresectable group,the non-excision rate was 75.0%.Conclusions Preoperative CT diagnosis of gastric carcinoma has important clinical significance.CT provides a high reference value for assessing the resectability of gastric carcinoma,and it is worthy of widespread use.
ABSTRACT
Objective To investigate the diagnosis,treatment and pathological characteristics of minute and small early gastric cancer(M EGC and S EGC).Methods The clinical and pathological parameters,and the diagnosis and treatment of 28 patients with M EGC or S EGC admitted to our hospital in recent 10 years were analysed retrospectively.Results There were 10 patients (12.4%) with M EGC,18( 22.2 %)with S EGC,and the proportion of M and S EGC in early GC is 34.6%.The diagnosis rate of gastric barium examination was 8.3% and that of gastroscopy with biopsy was 78.8%.All the carcinomas located in the body and antrum of the stomach.D1 radical gastrectomy(RGC) was performed on 6 patients and D2 RGC on the other 22 patients.The depth of tumor invasion in S EGC was significantly deeper than that in M EGC(P
ABSTRACT
Objective To analyse the clinical characteristics,diagnosis and treatment of gastric schwannoma. Methods The clinical data of 9 patients with gastric schwannoma were retrospectively analysed. Results The main manifestation in this series was as follows:abdominal pain(9 cases), abdominal mass(5 cases) and upper gastrointestinal hemorrhage(3cases).All the patients underwent surgery.None was diagnosed before the operation, 1 patient with malignant gastric Schwannoma died 8 months after the operation.The effect of operation for benign gastric schwannoma was nice.Conclusions Gastric schwannoma has no specific clinical characteristics preoperatively,and the misdiagnosis rate is high.Once the diagnosis of gastric Schwannoma is made,an operation should be performed as early as possible.
