Purpose:To evaluate the efficacy and toxicities of gemcitabine plus cisplatin for patients with relapsed ovarian cancer. Methods:Twenty-eight patients with recurrent ovarian carcinoma received gemcitabine (1000 mg/m~(2)) plus cisplatin (35 mg/m~(2)) on days 1 and 8 of each 21-day cycle. Of 28 patients, sixteen who relapsed within six months of previously platinum-based regimen were platinum-resistant and the other twelve were platinum-sensitive. Results:Of 28 patients, there were 5 (17.9%) complete and 12 (42.9%) partial responses, for an overall response rate of 60.7% (95%CI: 41.7%–79.6%). The median time to progression for objective responders was 5.5 months with a range of 2.5 to 20 months. Median overall survival for all 28 patients was 12.5 months. Among 16 platinum-resistant patients, a 56.3% response rate occurred. The median survival time was 10.5 months. Among 12 platinum-sensitive patients, a 66.7% response rate occurred. The median survival time was 14.5 months. There were leukopenia grade Ⅲ in 35.7%, grade Ⅳ in 17.9%; thrombocytopenia grade Ⅲ in 28.6 %, grade Ⅳ in 14.3% of patients. Conclusions:Cisplatin plus gemcitabine is active in patients with relapsed ovarian cancer. The adverse effects are tolerable. Hematologic toxicities are manageable with dose modifications.

Objective To compare contrast-enhanced ultrasonography (CEUS) features of clear cell renal cell carcinoma (CCRCC) and angiomyolipoma (AML), and to explore the value of CEUS for differential diagnosis. Methods CEUS appearance of 106 CCRCCs and 25 AMLs confirmed pathologically were analyzed retrospectively. For each lesion, the enhancement degree, the homogeneity of enhancement, the presence of perilesional enhancement, the washing-in and washing-out pattern and the process of enhancement (i.e. diffuse, centrifugal or centripetal enhancement) were evaluated. The results were compared with the pathologic findings. Results There was no statistically significance in the degree of enhancement and the washing-in and washing-out pattern between CCRCC and AML (P>0.05). However, significantly different was found in the homogeneity of enhancement, the presence of perilesional enhancement and the process of enhancement between CCRCC and AML (P<0.01). Heterogeneous enhancement, perilesional enhancement and diffuse enhancement were mainly seen in CCRCC, and the positive predictive value for CCRCC was 97.26%, 100% and 94.74%, respectively. When all the three CEUS findings combined were used as criterion for differentiating CCRCC from AML, the positive and negative predictive values was 100% and 95.00%, respectively. Conclusion CEUS characteristics of CCRCC is different from that of AML. CEUS is useful for the differential diagnosis of CCRCC and AML.

Objective To investigate the feasibility of contrast-enhanced ultrasonography (CEUS) combined with Bosniak classification in diagnosis of cystic renal cell carcinoma (CRCC). Methods Routine and contrast-enhanced ultrasonic manifestations of 24 patients (24 lesions) of CRCC confirmed with operation and pathology were retrospectively analyzed. The number of septa, thickness of wall and septa, with or without solid nodules and blood supply were evaluated. Each tumor was categorized on CEUS images using the Bosniak classification system, and the diagnostic coincidence rate was calculated. Results On routine ultrasonographic images, there were 2 lesions without septa, 8 with a few septa and 14 with multiple septa, 5 lesions with septa and (or) wall thickness ≤1 mm and 19 lesions thickness ＞1 mm; solid nodules were shown in 7 lesions and the color flow was shown in 11 lesions. On CEUS images, there were 8 lesions with a few septa and 16 with multiple septa, 1 lesion with septa and (or) wall thickness ≤1 mm and 23 lesions thickness ＞1 mm; solid nodules were shown in 9 lesions, and the enhancement could be demonstrated in all the lesions. According to Bosniak classification system, CEUS demonstrated 15 grade Ⅲ and 9 grade Ⅳ lesions. The diagnostic coincidence rate of CEUS combined with Bosniak classification was 100%. Conclusion The blood supply and sophisticated internal structures of CRCC can be shown better with CEUS than routine ultrasonography. CEUS combined with Bosniak classification can be used for the diagnosis of CRCC.

Objective To investigate the clinicopathologic features,the complications of splenectomy and the survival of epithelial ovarian cancer patients with splenic metastasis.Methods A retrospective study was performed of 32 pailents with epithelial ovarian cancer who underwent splenectomy for tumor cytoreduction at Zhejiang Cancer Hospital between Jan 1998 and Jun 2006.Results Of 32 patients,23 patients(72%)were serous adenocarcinoma and 9 were non-serous adenocarcinoma.According to pathological grade,none was of G1,11 were of G2,21 were of G3.Postoperatively,20 patients were left with no residual tumor.7 were with≤2 cm and 5 were with＞2 cm residual tumor.Postoperative complications developed in 8 patients(25%),including subphrenic abscess,wound infection,gastric perforation,gastrorrhagia,phlebothrombosis,and bowel obstruction.The median follow up was 38 months,estimated 2-year and 5-year overall survival were 70%and 36%.Univariate analysis revealed that histological grade,residual tumor and courses of chemotherapy were influencing factors of the survival(P＜0.05),but multivariate analysis indicated that only residual tumor and courses of chemotherapy independently influenced survival(P＜0.05).Conclusions In epithelial ovarian cancer patients with splenic metastasis,low grade serous adenocarcinoma is most common.Splenectomy as part of cytoreductive surgery is associated with modest morbidity and mortality.Residual tumor and courses of chemotherapy are independent factors associated with the prognosis of the patients.
