The AgNORs count in predicting long-term survival in serous ovarian cancer.

INTRODUCTION: The value of argyrophilic nucleolar organizer regions (AgNORs) to predict survival in patients with ovarian cancer has not been clearly explained yet. The aim of study was to assess the value of analysis of the mean number of AgNORs per nucleus (mAgNOR) and mean percentage of nuclei with five or more AgNORs per nucleus (pAgNOR) in the prediction of disease-free survival (DFS) and overall survival (OS) in patients with serous ovarian cancer. MATERIAL AND METHODS: The study examined 52 patients treated for serous ovarian cancer with a follow-up period of 2-143 months. After silver staining paraffin specimens from primary surgery, mAgNOR and pAgNOR in cancer cells were counted and analyzed. Age, grading, radicality of surgery and FIGO staging were analyzed as covariates. RESULTS: Mean mAgNOR equaled 4.4 ±0.9 and pAgNOR equaled 42.2 ±20.8%. Both mAgNOR and pAgNOR were the lowest in G1 tumors. The mAgNOR and pAgNOR were lower in stage I than stage IV cancers. The DFS and OS rates were respectively 15.4% and 21.2%. In univariate analysis FIGO staging, grading, and pAgNOR were associated with worse prognosis, while radicality of surgery remained a significant protective factor in terms of DFS. Higher FIGO staging and older age worsened OS. In multivariate analysis FIGO staging remained significantly associated with both DFS (HR 1.98; 95% CI 1.05-3.71) and OS (HR 1.76; 95% CI 1.00-3.10), while age affected OS rates (HR 1.78; 95% CI 1.04-2.95). CONCLUSIONS: mAgNOR and pAgNOR are useful markers of cellular kinetics. Prospective studies in larger populations are needed to confirm these results in terms of AgNORs' effects on survival.

[The value of progesterone and estrogen receptors expression in tissue microarray method in prognosis of patients with endometrioid endometrial cancer]. / Znaczenie ekspresji receptorów progesteronowych i estrogenowych ocenianej metoda mikromacierzy tkankowych dla rokowania u chorych z gruczolakorakiem endometrioidalnym endometrium.

OBJECTIVES: To assess prognostic significance of progesterone receptors (PR) and estrogen receptors (ER) expression in the tissue microarray (TMA) technique for disease free survival (DFS) and overall survival (OS) in endometrioid endometrial cancer (EEC). MATERIAL AND METHODS: The study included 151 consecutive patients, aged 37-86 years (62.80 +/- 9.99), with the EEC in stages I-III (FIGO), treated surgically at the Pirogow Memorial Hospital of Lodz between 2000 and 2007. Afterwards, they were subsequently treated and examined at the Regional Cancer Center, Copernicus Memorial Hospital of Lodz. Tissue cores 2 mm in size, in duplicate, were taken from the formalin-fixed and paraffin-embedded tissue donor blocks from surgery and constructed into the TMA recipient blocks. Using TMAs, the expression of PR and ER was examined and presented as Total Score (TS). The TS was determined by adding the intensity and marker distribution scores in a given case. The relationship between PR and ER expression, DFS and OS was examined. DFS was defined as the period from primary surgery until relapse. OS was defined as the period from primary surgery until the end of the follow-up (60 months) or until the death of the patient. The study was approved by the Ethics Committee of the Medical University of Lodz (RNN/82/11/KE). RESULTS: Lack of the PR and ER expression was found in 46 cases (30.46%) and 67 cases (44.37%), respectively. The expression of the PR and ER was weak in 24 cases (15.89%) and 22 cases (14.57%), respectively. Strong PR and ER expression was found in 81 patients (53.65%) and 62 patients (41.06%), respectively. Follow-up after surgery varied from 3 to 60 months (50.95 +/- 16.36). In 30 patients (19.87%) relapse was diagnosed 1-54 months (22.17 +/- 15.59) after surgery. During follow-ups, 29 patients (19.21%) died. In univariate analysis better DFS was related to the presence of PR (p = 0.010), higher TS of PR (HR = 0.81; 95% CI 0.71-0.94), the presence of ER (p = 0.001) and higher TS of ER (HR = 0.88; 95% CI 0.78-0.99). DFS differed significantly between the groups: without PR and ER expression (A), with presence of the PR but not ER expression (B), with the ER but not PR expression (C) and with the PR and ER expression (D) (p = 0.004). In univariate analysis OS was not related to PR expression (p = 0.110), TS of PR (HR = 0.89; 95% CI 0.80-1.02) and ER expression (p = 0.070). TS of ER was connected to better OS (HR = 0.83; 95% CI 0.72-0.96). The OS differed between groups A, B, C and D (p = 0.006). In multivariate analysis variants of PR/ER expression influenced the DFS (p = 0.039) and OS (p = 0.016). CONCLUSIONS: The expression of the PR and ER can significantly affect therapeutic decisions in selected patients with EEC. In EEC, common assessment of PR and ER expression is of higher prognostic value, than compared to single evaluation of PR and ER receptors.

Membrane expression of TRAIL receptors DR4, DR5, DcR1 and DcR2 in the normal endometrium, atypical endometrial hyperplasia and endometrioid adenocarcinoma: a tissue microarray study.

PURPOSE: To evaluate the membrane expression of DR4, DR5, DcR1 and DcR2 in the normal endometrium (NE), atypical endometrial hyperplasia (AEH) and endometrioid adenocarcinoma (EAC). METHODS: The study comprised 197 patients: 20 NE, 18 AEH and 159 EAC. Tissue microarrays were constructed. Membrane expression of DR4, DR5, DcR1 and DcR2 was examined and presented as total score (TS). RESULTS: In EAC, the membrane expression of DR4, DR5 and DcR2 was less common compared to NE (p < 0.001; p < 0.001; p = 0.018) and AEH (p < 0.001; p < 0.001; p = 0.004). In EAC the membrane expression of DcR1 did not differ when compared to NE (p = 0.055) and AEH (p = 0.173). A strong correlation was found between the type of endometrial tissue (NE/AEH/EAC) and the TS of DR4 (p < 0.001), DR5 (p < 0.001), DcR1 (p = 0.033) and DcR2 (p < 0.001). In EAC, the TS of DR4, DR5, DcR1 and DcR2 was not related to grading and staging. In EAC, the membrane expression of DR5, but not DR4, DcR1 and DcR2, was related to better disease-free survival (DFS). The overall survival (OS) was not related to membrane TRAIL receptors expression. CONCLUSIONS: The membrane expression of the receptors for TRAIL DR4, DR5, DcR1 and DcR2 is greater in NE than EAC. The level of membrane staining of the receptors in EAC is not dependent on grading and staging. In EAC patients, membrane expression of DR4, DR5, DcR1 and DcR2 are not independent predictors of survival.

Assessment of the argyrophilic nucleolar organizer region area/nucleus ratio in ovarian serous epithelial adenomas, borderline tumors and cancers.

INTRODUCTION: There is a need to assess the value of the novel potentially useful biomarkers in ovarian tumors. The aim of study was to assess the value of sAgNOR analysis in ovarian serous epithelial tumors. MATERIAL AND METHODS: The analysis was performed in ovaries from 113 patients treated operatively due to serous ovarian tumors (30 adenomas, 14 borderline tumors and 69 cancers). After silver staining of paraffin specimens from surgery, sAgNOR in tumor cells was analyzed. Additionally, the value of the argyrophilic nucleolar organizer region area/nucleus ratio (sAgNOR) in the prediction of disease-free survival (DFS) and overall survival (OS) in 52 patients with serous ovarian cancer with complete follow-ups in November 2009 was evaluated. Age, grading, radicality of surgery and FIGO staging were analyzed as additional factors. RESULTS: SAGNOR IN ADENOMAS, BORDERLINE TUMORS AND CANCERS WAS IN THE FOLLOWING RANGES: (0.73 ±0.23) × 10(6), (0.81 ±0.18) × 10(6) and (0.96 ±0.33) × 10(6) [AgNOR/cm(2)] respectively. In cancers from G1 to G3 sAgNOR was (1.02 ±0.32) × 10(6) (G1), (0.98 ±0.37) × 10(6) (G2) and (0.82 ±0.24) × 10(6) (G3) [AgNOR/cm(2)] respectively. In univariate analysis, but not in multivariate analysis, staging negatively correlated with better DFS and OS. sAgNOR, age of patients, grading and radicality of surgery were not associated with DFS or OS in either univariate or multivariate analysis. CONCLUSIONS: sAgNOR analysis is not sufficient to precisely characterize cellular kinetics in serous ovarian tumors, and the analysis of sAgNOR, mAgNOR and pAgNOR should be performed commonly. The prognostic significance of sAgNOR in patients with serous ovarian cancer was not proven.

[Effectiveness of tissue microarray technique for the assessment of estrogen and progesterone receptors expression in endometrioid endometrial cancer--preliminary report]. / Efektywnosc zastosowania techniki mikromacierzy tkankowych do oceny ekspresji receptorów estrogenowych i progesteronowych w gruczolakoraku endometrioidalnym endometrium--doniesienie wstepne.

OBJECTIVES: To assess the effectiveness of the donor-block biopsies with a 2 mm-size needle in endometrioid endometrial cancer (EEC) in the tissue microarray (TMA) technique and the application of the TMA for estrogen receptors (ER) and progesterone receptors (PR) expression in EEC. MATERIAL AND METHODS: The study examined EEC tissues from 60 patients. Tissue cores, 2 mm in size, in duplicate, were taken from the formalin-fixed and paraffin-embedded tissue donor blocks and constructed into the TMA recipient block. The presence of EEC tissue in the TMAs was analyzed, and the ER and PR expressions were examined. RESULTS: EEC tissue in TMAs was confirmed in 56 cases (93.33%). In 49 of them (81.67%), both cores presented with cancer tissues. In 4 cases (6.67%) EEC tissue was absent. All cases with ECC present on the TMA slides were appropriate for the ER and PR analysis. In 29 EEC cases (51.98%) both ER and PR were expressed. In 3 cases (5.36%) only ER was expressed, in 8 cases (14.29%) only PR was expressed, and in 16 cases (28.57%) ER and PR were assessed as negative. CONCLUSIONS: Two 2 mm-sized tissue cores from donor-block biopsies constructed into the TMA recipient block were sufficient to diagnose EEC and enabled the assessment of ER and PR expression in 93.3% of the cases. The use of the described TMA technique makes the immunohistochemical study of EEC easier and more time-efficient.

Comparison of prognosis in patients with endometrioid endometrial cancer staged IB in FIGO 1988 and 2009 classifications.

PURPOSE: Since 2009 the new FIGO Staging System of endometrial cancer, which changed the previous FIGO 1988 Staging System, has been in use. The aim of the study was to compare prognosis in patients with endometrioid endometrial cancer at stage IB of the 2009 FIGO Staging System and of the 1988 FIGO Staging System. METHODS: We analyzed 173 patients: 108 patients (group A) at stage IB in FIGO 1988 Staging System, and 68 patients (group B) at stage IB in FIGO 2009 Staging System from 262 consecutive endometrioid endometrial cancer patients. The disease-free survival (DFS) and overall survival (OS) were compared between these groups. RESULTS: The DFS rate was 96.3 % in group A and it was 87.7 % in group B (p = 0.029). Relapses were observed in 12 patients (6.4 %) from 6 to 57 months (mean 28.1; SD = 14.6) after initial surgery, and occurred in four patients from group A (3.7 %) and eight patients from group B (12.3 %) (p = 0.032). The OS rate was 94.4 % in group A and it was 83.1 % in group B (p = 0.018). During follow-up, 17 patients (9.8 %) died: six patients from group A (5.6 %), and 11 patients from group B (16.9 %). CONCLUSIONS: Stage IB in FIGO 2009 Staging System is associated with worse prognosis compared to stage IB according to FIGO 1988 classification. There seems to be a need to use exclusively the new FIGO 2009 classification worldwide to avoid therapeutic mistakes, which can be caused by diverse nomenclature.

[Endometrioid endometrial cancer--the prognostic value of selected clinical and pathological parameters]. / Gruczolakorak endometrium typu endometrioidalnego--analiza wartosci prognostycznej wybranych parametrów klinicznych i histopatologicznych.

OBJECTIVES: To assess the relationship between selected clinical and pathological factors and disease free survival (DFS) and overall survival (OS) in endometrioid endometrial cancer patients. MATERIAL AND METHODS: A retrospective review of 262 patients aged 37-86 (6.0 +/- 9.0) was performed. Selected clinical and pathological data were correlated with DFS and OS. RESULTS: Follow-up was 8-123 months (64.9 +/- 27.1). In 4 patients (1.5%) clinical progression was diagnosed during the treatment. In 43 patients (16.4%) relapse was diagnosed 2-61 months (23.9 +/- 15.7) after commencing treatment. DFS and OS were 82.1% and 81.3% respectively. In univariate analysis worse DFS was related to older patients (p = 0.007) and non-radical surgery (p < 0.001). In multivariate analysis worse DFS was related to older patients (HR = 1.058; 95% CI = 1.024-1.093; p < 0.001), younger at menopause (HR = 0.910; 95% CI = 0.851-0.973; p = 0.006), with higher staging (HR = 2.639; 95% CI = 1.968-3.539; p < 0.001) operated non-radically (HR = 0.220; 95% CI = 0.096-0.504; p < 0.001). In univariate analysis worse OS was connected with older patients (p = 0.018), diabetes type II (p = 0.019) and non-radical surgery (p < 0.001). In multivariate analysis worse OS was related to younger age at menopause (HR = 0.932; 95% CI = 0.873-0.996; p = 0.039), diabetes type II (HR = 2.372; 95% CI = 1.260-4.466; p = 0.008), higher staging (HR = 2.053; 95% CI = 1.482-2.845; p < 0.001), and non-radical surgery (HR = 0.240; 95% CI = 0.091-0.636; p = 0.004). CONCLUSIONS: Relapsed endometrial cancer developed in 90.7% during four years after commencing treatment. In 79.1% of these patients distant metastases were present. Most significant prognostic factors were radicality of surgery age of patients and staging. The presence of diabetes type II and early menopause were connected with worse prognosis.

[The results of screening program for cervical cancer in Lodz]. / Wyniki badania przesiewowego dla wczesnego wykrywania raka szyjki macicy u kobiet w regionie lódzkim.

OBJECTIVES: Despite effective screening methods, most often tumor of the urogenital tract is still cancer of the uterine cervix. Proven in many countries the value of widespread screening of the precancerous lesions and cervical cancer justifies carrying out such prophylactic tests in Poland. DESIGN: Assessment of results of screening as a method of early detection of cancer of the uterine cervix among inhabitants of Lódz area. MATERIAL AND METHODS: Study was done between 1.07.2000 and 31.12.2000 among 5,000 women aged from 30 to 59 years, inhabitants of Lódz area. Smears were evaluated in five-grade Papanicolaou scale and according to TBS system. In cases of detection of erosion of the uterine cervix or abnormal results of cytological test (> or = III degree) biopsies were taken to make pathological diagnosis. RESULTS: 459 smears were qualified to group I according to Papanicolaou (9.18%), 4435 smears to group II (88.7%), 38 smears to II/III (0.76%), 65 smears to group III (1.3%), 2 smears to IV (0.04%) and 1 smear to V (0.02%). Due to histopathological verification of the cytological results 53 low grade cervical dysplasia (1.06%) were diagnosed, 8 dysplasia of medium grade (0.16%), 7 high grade dysplasia (0.14%), 3 pre-invasive cancers (0.06%) and 3 invasive cancers (0.06%). CONCLUSIONS: Population of inhabitants of Lódz area aged 30 to 59 years old is characterised by a high frequency of incidence of pre-cancerous conditions and invasive cervical cancer. Number of detected pathologies of the uterine cervix proves purposefulness of this project.
