Lynch Syndrome-Related Clear Cell Carcinoma of the Cervix: A Case Report.

Lynch syndrome, a hereditary cancer syndrome, occurs because of germline mutations in at least one of four DNA mismatch repair genes (MutL Homolog 1 (MLH1), MutS Homolog 2 (MSH2), MutS Homolog 6 (MSH6), and PMS1 Homolog 2 (PMS2)). The disorder is associated with colorectal, endometrial, and other epithelial malignancies, but not cervical cancer. We report a woman with Lynch syndrome with synchronous cervical cancer. This is the first report of Lynch syndrome-related clear cell carcinoma of the cervix, which indicates the possibility of an association between cervical cancer and Lynch syndrome. Suitable genetic tests are required to determine whether common genetics can account for synchronous or subsequent malignancies in Lynch syndrome patients and their families. Such knowledge will also enhance our understanding of the genetic mechanisms governing the development of apparently unrelated cancers.

Preoperative tumor size is associated with deep myometrial invasion and lymph node metastases and is a negative prognostic indicator for patients with endometrial carcinoma.

We examined the usefulness of evaluating tumor size determined using preoperative magnetic resonance imaging (MRI) for prognosis in patients with endometrial carcinoma (EC). Patients (N = 184) with EC who underwent surgery at Shimane University Hospital between 1997 and 2013 were enrolled. We investigated the association between the tumor size of EC assessed prior to surgery by MRI (anteroposterior [AP], transverse [TV], and craniocaudal [CC] diameters) and various clinical parameters including deep myometrial invasion and lymph node metastases. We subsequently examined the prognostic significance of tumor size in patients with EC. Survival analysis was performed using the Kaplan-Meier method, and prognostic factors were evaluated using the Cox's proportional hazards regression model. Multivariate analysis identified increased AP diameter as an independent negative prognostic factor for overall survival (OS) (P = 0.037). A long AP diameter has prognostic value and the potential to be a predictive marker for surgical outcomes in patients with EC. Furthermore, AP diameter exhibited the greatest area under the curve (AUC) (0.727) for deep myometrial invasion, and CC diameter had the greatest AUC for lymph node metastases (0.854). Evaluation of tumor size parameters may aid in the identification of high-risk populations, which could improve treatment selection and patient outcomes.

Prognostic significance of pre-treatment neutrophil-to-lymphocyte and platelet-to-lymphocyte ratios in non-surgically treated uterine cervical carcinoma.

The aim of the present study was to assess the prognostic significance of the pre-treatment neutrophil-to-lymphocyte ratio (NLR), the platelet-to-lymphocyte ratio (PLR) and other clinicopathological characteristics in patients with non-surgically treated uterine cervical carcinoma. The correlations of clinicopathological characteristics with overall and progression-free survival were determined in 98 Japanese patients who received non-surgical treatment for uterine cervical carcinoma between January 1997 and July 2013. Survival rates were calculated using the Kaplan-Meier method and potential prognostic indicators were assessed using a Cox proportional hazards model. A total of 68 patients (69.4%) had a high pre-treatment NLR (≥3.5) and 34 patients (34.7%) had a high pre-treatment PLR (≥212). Both NLR and PLR were found to be positively correlated with pre-treatment platelet counts. Multivariate analysis identified NLR and carcinoembryonic antigen level, but not PLR, as independent predictors of overall and progression-free survival. In conclusion, the present study identified two prognostic indicators for uterine cervical carcinoma, both of which can be easily and cost-effectively monitored via blood testing.

Ultrasound-guided intranodal lymphangiography with lipiodol for treatment of chylous ascites following surgery for ovarian cancer: A case report.

Although lymphadenectomy for gynecological cancer is often associated with chylous leakage, the proper management of this complication remains a matter of debate. In the present study a case of chylous leakage successfully treated with lipiodol lymphangiography is described. A 33-year-old patient with ovarian cancer experienced chylous leakage following total abdominal hysterectomy, bilateral salpingo-oophorectomy, omentectomy, and pelvic and para-aortic lymphadenectomy. The volume of fluid in the abdominal drainage tube increased to 800-1,000 ml/day on postoperative day (POD)3. The patient was started on a fat-restricted diet on POD3 and octreotide on POD21, but the volume of the discharge remained unchanged. Lipiodol lymphangiography was performed on POD62, which reduced the leakage, and the patient was discharged on POD95. Therefore, lipiodol lymphangiography effectively resolved chylous leakage following surgery for gynecological cancer. The aim of the present study was to report the clinical effectiveness of lipiodol lymphangiography in resolving chylous leakage in such cases, and to summarize the methods used and complications encountered.
