A radical hysterectomy was performed on patients with stage IA2 to IIB cervical cancer. For these patients, many histopathological parameters have been reported to be prognostic factors of cervical cancer, such as a pelvic lymph node (PLN) metastasis, the histological subtype, the tumor diameter, the depth of the stromal invasion, a lymph-vascular space invasion (LVSI), a parametrial invasion, a corpus invasion and a vaginal invasion. Ovarian cancer is normally treated with cytoreductive surgery followed by chemotherapy. Although physicians have paid a great deal of attention to intraperitoneal disease, a substantial number of ovarian cancers have reported to involve the retroperitoneal lymph nodes. Therefore, a lymph node metastasis has been introduced into FIGO staging. However, the prognostic significance of a lymph node metastasis is controversial. In order to determine the possibility of individualizing a pelvic lymph node (PLN) dissection in patients with endometrial cancer, the relationship between PLN metastasis and the various prognostic factors was investigated. In this paper, various prognostic variables including a lymph node metastasis were analyzed in cervical cancer, enodometrial cancer, and ovarian cancer.

To determine the cytologic and histologic correlation of atypical glandular cells of undetermined significance (AGUS) in Papanicolaou smears, a cytology file from January 1998 to May 1999 was reviewed. Surgical pathology files were searched to determine which patients received subsequent biopsies. One hundred thirty-two patients with AGUS were identified. Corresponding biopsies were available for 82 of these cases. AGUS has been sub-classified into 3 subtypes: 1) AGUS, favor reactive; 2) AGUS, not otherwise specified; and 3) AGUS, favor neoplasia. The pathologic findings for the respective Papanicolaou smears with the diagnosis of each subtype of AGUS through the follow-up period were as follows: benign lesions in 56.1%, 0%, and 1.2%; squamous intraepithelial lesions 2.4%, 0%, and 1.2%; glandular intraepithelial lesions 0%, 0%, and 17.1%; endometrial simple hyperplasia 1.2%, 0%, and 0%; and carcinoma 0%, 9.8%, and 11%, respectively. In conclusion, AGUS, on cervical cytologic screening, was correlated with significant pathologic findings in 41.5% of the patients (37.8% with preinvasive or invasive glandular lesions and 9.6% with combined squamous intraepithelial lesions). It is thought that intensive follow-up studies, including colposcopy, cervical biopsy, and curettage, should be recommended for complete evaluation of AGUS.

Fourier transformation infrared microspectroscopy (FTIR-MSP) mapping technique can collect the infrared information from micro-samples and scan the tissue slides and cells. The infrared spectral information of pixels from the collected regions is recorded and infrared spectral maps are constructed by computer software. The 2D and 3D mapping images are reflected based on the distributions of absorbance bands. The biochemical compositions, molecular distribution, metabolic changes of tissues and cells are analyzed by the technique due to infrared spectroscopy being sensitive to biomolecules. The article reviews the recent research of FTIR-MSP mapping and explores the future potential value in forensic science practice.

OBJECTIVE: To identify key factors for predicting positive cone margin and appropriate cone length. METHODS: We retrospectively reviewed the margin status of patients who received conization with high grade cervical intraepithelial neoplasia, along with other factors such as patient age, parity, preoperative cytology, size of disease, type of transformation zone, and cone length from patient records. Cut-off value of cone length was analyzed in women younger than 40 years old because we design conization with minimum length especially for women who wish for future pregnancy. Cut-off value of cone length was defined as length corresponds to estimated probability of positive cone margin equal to 0.1 by logistic regression analysis with variables selected by stepwise methods. RESULTS: Among 300 patients, 75 patients had positive cone margin. Multivariable analysis revealed that squamous cell carcinoma at preoperative cytology (p=0.001), 2 or more quadrant disease (p=0.011), and shorter cone length (p<0.001) were risk factors for positive cone margin. Stepwise methods identified cone length and size of lesion as important variables. With this condition, cut-off value of cone length was estimated as 15 mm in single quadrant disease and 20 mm in 2 or more quadrant disease, respectively. CONCLUSION: We identified the independent risk factors of positive cone margin and identified the cut-off value of cone length to avoid positive cone margin in women younger than 40 years old. Conization should be performed not only according to colposcopic findings including type of transformation zone but size of disease and cone length.

Ewing's sarcoma in the cervix is characterized by extremely rare occurrence,high degree of malignancy,and rapid progression.The diagnosis of this disease is based on pathology and immunohistochemistry. The main image of the case reported in this paper showed the cervical cyst with solid mass,large volume,and uneven density and signal,and the solid part can be strengthened in enhanced scanning.Because of the rapid growth,the lesion is prone to liquefaction necrosis and bleeding.Since the metastasis occurs early,timely diagnosis is essential.
