5-YEAR SURVIVAL OF PATIENTS WITH STAGE II UTERINE CANCER DEPENDING ON MORPHOLOGIC FEATURES OF TUMOR

Retrospective data of treatment results of 109 patients with rarely observed stage II uterine cancer, admitted to N.N. Blokhin Russian Cancer Research Center from 1980 to 2000 is analyzed. Correlation of overall 5-year survival rates of stage IIA and IIB uterine can- cer patients with a number of tumor morphologic features is studied. The influence of some non-elucidated morphologic features of stage IIA and IIB uterine cancer such as the degree of cellular anaplasia, the depth of tumor invasion into the uterine neck, lymho- vascular invasion into the myometrium and uterine neck, microscopic vessels density in the area of the most extensive invasion, the presence of necrotic areas in the tumor tissue on long-term treatment results are analyzed

CLINICAL CHARACTERISTICS OF OVARIAN CLEAR CELL CANCER

The research has enrolled 96 patients with rare ovarian clear cell cancer treated at N.N. Blokhin Russian Cancer Research Center from 1978 to 2000. A necessity to divide patients into two groups has emerged after histopathological slide review. The first group included 71 patients with ovarian clear cell carcinoma (OCCC). Twenty five patients with mixed malignant epithelial ovarian tumor (MMEOT) with mandatory presence of clear cell component were included into the second group. Clinical par- ticularities of clear cell ovarian cancer were studied. We performed a comparative study of clinical course of OCCC and MMEOT. Our data suggest that clear cell ovarian cancer has a number of typical clinical and biological particularities both in OCCC and MMEOT

Impact of the morphological signs of Stage II corpus uteri cancer on the occurrence of recurrences and metastases

The paper gives the rates of recurrences and metastases occurring after primary therapy in 109 patients with Stage II corpus uteri cancer (CUC) treated at the Unit of Gynecology, N.N. Blokhin Russian Cancer Research Center.The distribution of patients with Stages IIA and IIB CUC is shown by the rates of recurrences and metastases; the time of their emergence is defined; the mean survival is estimated in patients with progressive CUC. The distribution of patients with recurrent Stage II CUC and separately its metastases is considered in relation to the early unstudied morphological characteristics of primary tumor

Tumor markers in the diagnosis of cancer of the corpus uteri (a review of literature)

Towards the end of the past century, cancer of the corpus uteri achieved the status of leading gynecologic cancer not only in developed countries, but also in Third World countries. The leading determinants of prognosis and treatment policy are tumor extent and grade at diagnosis. It is important to search for the informative and significant indicators of biological tumor activity, which are determined by pre- and postoperative mini-invasive laboratory studies, the combination of which could additionally judge the extent and grade of a tumor. At present, there are no significant tumor markers for the screening for and evaluation of progressive cancer of the corpus uteri, which would have a high specificity and sensitivity although their search is constantly underway worldwide

The pathomorphological characteristics of clear-cell adenocarcinomas of the ovary and its mixed tumors with a clear-cell component

Objective: to study the pathomorphological signs of pure and mixed clear-cell ovarian tumors with a clear-cell component.Subjects and methods. The clinical and morphological characteristics and the course of the disease were analyzed in 96 patients aged 21 to 75 years with clear-cell ovarian carcinoma. All the patients were divided into 2 groups: 1) 71 patients with pure clear-cell ovarian adenocarcinomas (COA) and 2) 25 patients with mixed malignant ovarian epithelial tumors (MMOET) with an obligatory clear-cell component. All pure forms of ovarian clear-cell malignancies were represented by adenocarcinoma in our study. This histologic type of the tumor was also prevalent among mixed ovarian neoplasms.Results. Clear, optically transparent cells and shoe nail-type (nail) ones were most common in COA. MMOETs showed moderate dif- ferentiation and malignancy and moderate atypia of a cell. Pure clear-cell neoplasms generally displayed 3 to 6 mitoses in 10 fields of vision whereas MMOET exhibited as many as 3 mitoses in 10 fields of vision

Treatment results and prognostic factors of clear cell ovarian carcinomas and ovarian carcinomas with clear cell component

The most important prognostic factors for clear cell carcinoma (CCC) are clinical and morphological signs and clinical stage of the disease. Analyses of 5-year survival in patients with I stage of CCC is 69 %, in II stage – 55 %, in III stage – 14 % and in IV stage – 4 % patients. We analyzed distant results of treatment of 71 patients with CCC and of 25 patients with mixed malignant ovaries neoplasm with obligatory clear cell component taking into consideration main clinical and morphological sings of disease. On the base of performed reseal we revealed that morphological structure of the tumors and stage of the disease exerted heist influence on the exponent of survival of the patients with clear CCC ovaries neoplasm. Besides, there is a correlation between exponent of patients’ survival and radicalized of surgery, character of tumor growth, differentiation degree, cell anaplasia and mitotic activity of tumor cells

Mass spectrometry is a new approach to diagnosing adenomyosis and cancer of the corpus uteri

Sera from 60 apparently healthy women (mean age 40 years; a control group), 40 patients with a verified diagnosis of adenomyosis (mean age 41 years) and 42 patients with uterine corpus cancer (UCC) (mean age 58 years) were fractionated on magnetic beads with weak cation exchange surface, followed by an examination of the obtained fractions by time-of-flight mass spectroscopy (MS) with ma- trix-activated laser desorption/ionization. MS data analysis using classification algorithms, such as a genetic algorithm and a learning neural network, made it possible to construct mathematical models that were able to differentiate MS profiles of the above sample groups with a high specificity and a high sensitivity. The best values of the specificity and sensitivity of the classification models adenomyosis- control and UCC-control were 86.2, 93.8, 90.5, and 90.5%, respectively. Analysis of the statistical diagrams of these peak areas between different sample groups could identify 3 MS profile peaks for adenomyosis and 3 peaks for UCC
