OBJECTIVETo investigate the development regularity, treatment methods and prognosis of ovary immature teratoma (POIT).

METHODSSixty-seven patients with POIT, admitted from 1958 to 1998, were retrospectively analyzed. There were 31 patients with stage I, 4 with stage II, 2 with stage III and 1 with stage IV lesions. Twenty-seven patients had recurrences and 2 had distant metastases. Unilateral adnexectomy was performed for stage I lesions. From the 1980s, this was followed by four-cycles of combination chemotherapy (VAC, PVB or BEP x 3 cycles) as post-operative adjuvant therapy. Combined chemotherapy and multiple operations were performed for advanced and recurrent lesions.

RESULTSThe overall survival rate was 75% (50/67). However, there was a remarkable difference in the results from the various periods. From 1958 to 1983, the 5-year survival rate was 40% (6/15), and it was raised to 79% (26/33) from 1984 to 1993. In the period 1994 to 1998, 95% (18/19)of patients were rescued. Thirty-five patients who had early lesions (stage I and II) had a 5-year survival rate of 91.4% (32/35). Thirty-two patients with recurrent or advanced lesions had a 5-years survival rate of 56% (18/32). There were 8 patients with grade III tumors and their 5-year survival rate was only 25% (2/8). The chief prognostic factors for this disease are clinical stage, pathological grade and adequate treatment.

CONCLUSIONPOIT is a potentially curable disease in today's practice. It is characterized by the fact that recurrent tumors may be converted back to mature ones as time goes on. With chemotherapy, these is a good opportunity to rescue those patients with recurrent tumors. At present, treatment of POIT gives the most satisfactory results among all malignant ovarian germ cell tumor types. Tests of serum specific tumor markers (CA19-9, AFP, CA125, CEA) performed preoperatively or before chemotherapy and during follow-up have been found helpful in the evaluation of prognosis.

OBJECTIVE: Distal pancreatectomy with splenectomy may be required for optimal cytoreductive surgery in patients with epithelial ovarian cancer (EOC) metastasized to splenic hilum. This study evaluates the morbidity and treatment outcomes of the uncommon procedure in the management of advanced or recurrent EOC. METHODS: This study recruited 18 patients who underwent distal pancreatectomy with splenectomy during cytoreductive surgery of EOC. Their clinicopathological characteristics and follow-up data were retrospectively analyzed. RESULTS: All tumors were confirmed as high-grade serous carcinomas. The median diameter of metastatic tumors located in splenic hilum was 3.5 cm (range, 1 to 10 cm). Optimal cytoreduction was achieved in all patients. Eight patients (44.4%) suffered from postoperative complications. The morbidity associated with distal pancreatectomy and splenectomy included pancreatic leakage (22.2%), encapsulated effusion in the left upper quadrant (11.1%), intra-abdominal infection (11.1%), pleural effusion with or without pulmonary atelectasis (11.1%), intestinal obstruction (5.6%), pneumonia (5.6%), postoperative hemorrhage (5.6%), and pancreatic pseudocyst (5.6%). There was no perioperative mortality. The majority of complications were treated successfully with conservative management. During the median follow-up duration of 25 months, nine patients experienced recurrence, and three patients died of the disease. The 2-year progression-free survival and overall survival were 40.2% and 84.8%, respectively. CONCLUSION: The inclusion of distal pancreatectomy with splenectomy as part of cytoreduction for the management of ovarian cancer was associated with high morbidity; however, the majority of complications could be managed with conservative therapy.

OBJECTIVETo investigate the therapeutic principles and prognosis of synchronous primary colorectal carcinomas (SCC).

METHODSThe data of 66 SCC patients surgically treated from 1984 to 2003 were retrospectively reviewed.

RESULTSThe synchronous primary colorectal carcinomas were diagnosed and resected simultaneously in 65 patients except one that was misdiagnosed. Thirty patients underwent combined resection, 35 patients segmental resection. Sixty-two patients received radical resection, while three patients had palliative resection due to hepatic metastasis. The overall postoperative 3-, 5-, 10-year survival rates were 70.3%, 60.0%, 40.6%, respectively. In the patients who had simultaneous radical resection, the 3-, 5-, 10-year survival rates were 76.0%, 65.9%, 46.4% respectively.

CONCLUSIONThe extent of resection should be individually determined by the lesion location, extent and distance between the lesions, as well as the patient's general condition. More extensive bowel resection, such as total or subtotal colectomy are suggested for those patients with hereditary nonpolyposis colorectal carcinoma syndrome in order to reduce or avoid the risk of metachronous colorectal carcinoma. The postoperative survival in patients with synchronous primary colorectal carcinoma is similar to those with solitary lesion.

OBJECTIVETo evaluate the impact of lymphadenectomy on the relapse and survival of malignant ovarian germ cell tumor (OGCT).

METHODSThe clinical data of 102 OGCT cases treated in Peking Union Medical College Hospital from June 1980 to June 2003 were analyzed retrospectively. All the data about lymphadenectomy during primary and secondary surgery were collected, and other factors related to prognosis were also collected at the same time. Chi-squared test was applied in the univariate analysis related to relapse of disease. Cox model was applied in multivariate analysis related to relapse and survival of disease.

RESULTSPelvic and paraaortic lymph node metastasis was not significantly related to prognosis in primary and secondary treated patients. Lymphadenectomy showed no significant impact on disease relapse and survival. In the primary treatment, International Federation of Gynecology and Obstetrics (FIGO) staging, chemotherapy regimen, residual tumor and lymphadenectomy were the significant factors related to the relapse. After being stratified for the chemotherapy regimen, lymphadenectomy was not significantly related to the relapse in bleomycin +etoposide +cisplatin or cisplatin +vincristine +bleomycin regimen group, and lymphadenectomy could prevent relapse in no chemotherapy or other chemotherapy regimen group. In relapsed patients, only residual tumor was significantly related to survival time after relapse.

CONCLUSIONSPelvic lymph node metastasis is not the significant risk factor related to prognosis. Lymphadenectomy may have a beneficial effect on survival, although such effect is not significant. Although lymphadenectomy provides important information for prognosis, they provide little benefit to those patients already requiring chemotherapy based on the original operative findings. Lymphadenectomy should be performed to primary or relapsed patients by an expert surgical team.

We performed a retrospective study to evaluate the feasibility and safety of extensive upper abdominal surgery (EUAS) in elderly (> or =65 yr) patients with advanced ovarian cancer. Records of patients with advanced epithelial ovarian cancer who received surgery at our institution between January 2001 and June 2005 were reviewed. A total of 137 patients including 32 (20.9%) elderly patients were identified. Co-morbidities were present in 37.5% of the elderly patients. Optimal cytoreduction was feasible in 87.5% of the elderly while 95.2% of young patients were optimally debulked (P=0.237). Among 77 patients who received one or more EUAS procedures, 16 (20.8%) were elderly. Within the cohort, the complication profile was not significantly different between the young and the elderly, except for pleural effusion and pneumothorax (P=0.028). Elderly patients who received 2 or more EUAS procedures, when compared to those 1 or less EUAS procedure, had significantly longer operation times (P=0.009), greater blood loss (P=0.002) and more intraoperative transfusions (P=0.030). EUAS procedures are feasible in elderly patients with good general condition. However, cautious peri-operative care should be given to this group because of their vulnerability to pulmonary complications and multiple EUAS procedures.
