The association of polypoid growth pattern with lymph node involvement in endometrioid type endometrial adenocarcinoma

Background

Tumor size is an independent predictor of lymph node metastasis and survival in the endometrioid type endometrial adenocarcinoma (EC). However, some of the ECs tend to grow towards the cavity in the polypoid pattern, which can reach very large sizes. In this study, we aimed to analyze the association of growing in the polypoid pattern of the tumor with the proportion of lymph node metastasis and extrauterine tumor spread.

Methods

Four hundred seven patients were analyzed retrospectively. The effect of tumor size, tumor growing pattern, myometrial invasion, grade, and lymphovascular space invasion on the lymph node metastasis and extrauterine tumor spread were investigated. Statistical analysis consisted of unpaired t-tests for parametric data and Mann Whitney-U test for non-parametric data, whereas the Chi-square test for categorical variables. Logistic Regression, Cox Regression and multivariate analysis were used to estimate the risk predictors.

Results

No association was found between the growing in polypoid pattern and lymph node metastasis (P > 0.05). In the analysis of endometrioid type EC patients who had myometrial invasion less than ½ as a subgroup, no association was found between the growing pattern and lymph node metastasis and extrauterine disease. Tumor size was found to be a statistically significant predictor of lymph node metastasis and extrauterine disease (P < 0.05).

Conclusions

Lymphovascular space invasion, grade, and myometrial invasion are associated with a higher proportion of lymph node metastasis. The polypoid growth pattern of the tumor does not correlate with any histopathological parameters.

The impact of uterine adenomyosis on the histopathological risk factors and survival in patients with endometrial adenocarcinoma

A retrospective cohort study was performed on patients diagnosed with endometrial adenocarcinoma (EC) during a 9-year period to investigate the impact of co-existing adenomyosis on patients with EC. Group A included women with EC and adenomyosis and Group B EC cases without the presence of adenomyosis. Group A was more likely to have early-stage disease, tumours without deep myometrial invasion, low-grade tumours and tumours with negative lymphovascular space invasion when compared to Group B (p = 0.012, p = 0.004, p < 0.001, p = 0.02). There were no statistically significant difference between Group A and Group B for lymph node metastasis (p = 0.064). There was no significant relation between the adenomyosis and survival outcomes in the multivariant analysis (p = 0.437). As a conclusion, patients with adenomyosis were more likely to accompany good histopathologic prognostic factors. Multivariate analysis showed no significant effect of adenomyosis on recurrence and survival parameters.IMPACT STATEMENTWhat is already known on this subject? Adenomyosis is one of the most common accompanying benign histopathological findings of type 1 endometrial carcinomas (EC). Adenomyosis comprises some characteristics similar to malignant tumours, such as invasion, abnormal tissue growth and angiogenesis. Despite concerns have arisen due to both their high incidence and similar molecular links, the possible relation between EC and adenomyosis is still not well grounded.What the results of this study add? We presented a 9-year period retrospective cohort of a tertiary referring single centre and evaluated the prognostic effect of adenomyosis in patients with EC as well as the survival outcomes of these patients. The co-occurrence of adenomyosis was more likely to accompany early-stage (stages 1-2) disease, low-grade tumours (grades 1-2) and tumours with negative LVSI in patients with EC. However, multivariate and survival analysis showed no significant effect of adenomyosis on recurrence and survival parameters.What the implications are of these findings for clinical practice and/or further research? Based on these findings, we suggest that the presence of adenomyosis should not be considered as a prognostic factor in EC. Our results support the overriding opinion about the prognostic value of co-occurrence of adenomyosis and EC. However, further studies exploring the molecular and genomic markers in these two groups are needed to uncover the exact relation of adenomyosis on the prognosis of EC.

Endothelial nitric oxide synthase G894T, intron 4 VNTR, and T786C polymorphisms in retinopathy of prematurity

BACKGROUND

Our objective in this study was to assess the association between eNOS gene, that achieves synthesis of nitric oxide especially in the endothelial cells known to have an important role in angiogenesis and vasculogenesis, G894T, intron 4 VNTR (27-bp repeat) and T786C functional polymorphisms and retinopathy of prematurity (ROP), which is an important cause of morbidity in premature or low birth weight babies.

METHODS

A total of 139 babies who were followed up in our neonatal intensive care unit because of premature birth in our hospital or admitted to our unit. 69 of them had retinopathy of prematurity and comprised the patients group. The remaining 70 babies who did not have ROP comprised the control group. An additional of 1 ml of blood samples were drawn from babies who were in the study groups during routine laboratory analysis. eNOS gene polymorphisms were determined by using polymerase chain reaction method.

RESULTS

eNOS G894T, intron 4 VNTR and T786C gene polymorphisms did not differ between the patient and control groups (p >  0.05). Using logistic regression analysis; while gender did not differ between two groups; gestational age, birth weight, time on mechanical ventilation differ between two groups. After adjustment for variables other than eNOS gene polymorphisms, we found no significant difference in the genotype distribution of eNOS G894T, intron 4 VNTR and T786C polymorphisms (p >  0.05).

CONCLUSION

We observed no association between ROP and eNOS gene polymorphisms but needs more investigation.

Clinicopathological analysis of invasive cribriform carcinoma of the breast, with review of the literature

Invasive cribriform carcinoma (ICC) is a rare type of a primary breast carcinoma. It is subdivided into two groups as pure and mixed types. There are limited studies comparing the pure and mixed ICC at present. We aim to investigate the clinicopathological, radiological, prognostic features, and survival outcomes of two types with reviewing the published literature. 16 pure ICC and 26 mixed ICC cases were evaluated. The population consisted of 41 female and 1 male patients. The only male patient was a pure ICC case. The median age was for pure and mixed type, 46.5 and 54 years, respectively. All ICCs were ER positive. All ICCs except one mixed ICC, were positive for PR. Only one mixed ICC was accepted HER2 positive (3+). Pure ICCs showed more favorable features than mixed ICCs such as lesser axillary lymph node involvement, lower grade, and proliferation index. Twenty-five patients had one of the following imaging methods; ultrasonography (US), mammography (MG), and magnetic resonance imaging (MRI). Irregular shape, hypoechogenicity, and spiculated margins were the most common US findings. Similarly, irregular shape+spiculated margin is the most common MG findings. The median follow-up time for pure and mixed ICC was 88 and 56.5 months, respectively. One mixed ICC case developed bone metastasis. One death occurred in each group. Reasons of death were unknown. The 5-year OS for both ICC groups was 100%. 10-year OS for pure and mixed ICCs was 100% and 90%, respectively. 5-year DFS was 100% for pure ICC, and 94% for mixed ICC.

A New Imaging Workup of The Male Breast: Single-View Mammography and Ultrasonography

Background: There is no generally accepted standard radiological approach to male breast diseases. Ultrasonography and mammography are the most preferred methods for imaging. The purpose of this study is to investigate the diagnostic performances of only single-view (mediolateral oblique) mammography and routine two-view mammography in the male breast diseases and also to evaluate the contribution of ultrasonography to the diagnosis and the management of the disease.Methods: Three hundred-twenty male patients’ breast imaging findings were evaluated retrospectively. Only mediolateral oblique and routine two-view mammograms were re-evaluated four months apart by two breast radiologists. The kappa value was calculated to measure consistency between two groups. The sensitivity, specificity, positive and negative predictive value, and detection accuracy of malignancy were calculated for both mammographic examinations and ultrasonography.Results: The accuracy of detection of malignant breast masses according to mediolateral oblique and two-view mammograms, and ultrasonography were 96.3 %, 97.5 %, and 99.5 %, respectively. Consistency between single-view and two-view mammograms was excellent (? = 0.967) and statistically significant (p=0.000). Two-view mammograms did not make any contribution to single-view mammograms.Conclusion: Only mediolateral oblique mammogram is sufficient in terms of characterization, spread and localization of the lesion, as long as mastectomy is preferred and the findings are supported by ultrasonography. Since there is no diagnostic performance difference, only mediolateral oblique view would protect from the potential adverse effects of extra radiation exposure and this is an important advantage.

Epithelioid trophoblastic tumor in a postmenopausal woman: A case report and review of the literature in the postmenopausal group

Epithelioid trophoblastic tumor is a rare gestational trophoblastic neoplasm arising from the intermediate trophoblasts. Although usually seen in the reproductive period, it may be encountered during the postmenopausal period. A 56-year-old woman who had given her last birth 21 years ago presented to the hospital with a complaint of postmenopausal bleeding. She had a history of eight live pregnancies and had been in menopause for 4 years. With the help of typical histopathologic and immunohistochemical findings, a diagnosis of "epithelioid trophoblastic tumor" was made. The diagnosis was made at an advanced age and the case had extraordinary features such as high mitotic activity and Ki-67 proliferation index (70%). Gestational trophoblastic neoplasms are rare causes of postmenopausal bleeding which may cause differential diagnosis problem. They should be kept in mind even if the patient age does not comply with because of the differences in treatment.

Does cervicovaginal cytology have a role in the diagnosis and surveillance of endometrial adenocarcinoma?

OBJECTIVE

To examine the role of cervicovaginal cytology in diagnoses and surveillance of the patients with endometrial carcinoma (EC).

METHODS

Patients who underwent EC surgery that included a follow-up were reviewed retrospectively. The cohort was limited to the patients who had an available cervical cytology result within 12 months before the primary surgery took place. The glandular abnormalities were classified in the following subclassifications: "atypical glandular cells" (AGC)-not otherwise specified (NOS), AGC-favor neoplasia, endocervical AIS, and adenocarcinoma.

RESULTS

A total of 411 patients were eligible for the study. The cervical cytology was found to be normal and recorded as negative for intraepithelial lesion or malignancy in 368 (89.5%) patients. In 43 (10.5%) patients, cervical cytology was interpreted as: AGC-NOS (n = 11), AGC-FN (n = 7), adenocarcinoma (n = 20), malignant epithelial tumor (n = 3), and squamous carcinoma (n = 2). During the follow-up, recurrence was observed in 53 (12.9%) patients. Among six isolated vaginal cuff recurrences, two of the cases presented with malignant cytology, and the additional four cases were suspected during clinical examination. Among women with recurrence (n = 53), there were malignant cytological findings in four of the patients. In the whole population (n = 411), there were four other abnormal cytological findings detected within the surveillance. These four cytology results were nonmalignant and no recurrence was identified.

CONCLUSION

There is no significant clinical advantage of cervicovaginal cytology testing before diagnosis or during the surveillance of EC.

High expression of mesothelin in advanced serous ovarian cancer is associated with poor prognosis

PURPOSE

Mesothelin is a cell surface glycoprotein which is highly expressed in various types of epithelial cancers. Its expression level is associated with poor prognosis in many cancer types. The aim this study was to evaluate the association of the level of mesothelin expression with clinicopathological characteristics and its prognostic significance in patients with advanced serous ovarian cancer (SOC).

METHODS

Tissue blocks from a total 42 patients with advanced SOC treated at the medical oncology clinic of Izmir Katip Celebi University Ataturk Training and Research Hospital between 2006 and 2013 were evaluated. Immunohistochemical staining for mesothelin was performed. Clinical characteristics, optimal or suboptimal operation, response to platinum-based chemotherapy, and overall survival (OS) were analyzed.

RESULTS

The cut-off value of 45 for mesothelin H-score determined by ROC analysis predicted survival with 86% sensitivity and 75% specificity (p=0.020). We found a notable negative correlation between mesothelin H-score and OS (r = -0.570, p=0.0001). The median OS was 67 months (95%CI, 36.114 to 97.886) in the low-staining mesothelin H-score group and 27 months (95%CI, 22.238 to 31.762) in the high-staining mesothelin H-score group (p=0.002). Univariate analysis showed that the clinical stage IV disease (p=0.023), platinum chemoresistance (p=0.001), higher mesothelin H-score (p=0.002), and suboptimal surgery (p=0.024) were associated with worse OS. In the multivariate Cox regression model, mesothelin H-score (B=1.15, 95%CI=1.016 to 9.850, p=0.047) and the status of platinum sensitivity (B=-.916, 95%CI=.185 to -.864, p=0.020 were statistically significant predictors for OS.

CONCLUSION

These results indicated that high mesothelin H-scores were significantly associated with poor prognosis in patients with advanced SOC.

Oncocytic and tall columnar type papillary thyroid carcinoma arising on a mature cystic teratoma: A case report and literature review

Mature cystic teratoma (MCT) is the most common germ cell ovarian tumour, which accounts for 15-20% of all ovarian neoplasms. The frequency of MCT cases undergoing malignant transformation ranges from 0.17% to 2%. Our aim for presenting this case is to contribute to formation of an algorithm in the literature for the treatment and follow-up of MCT undergoing malignant transformation. A 38-year-old female patient presented to the emergency service with acute abdomen. The patient underwent salpingo-oophorectomy due to a prediagnosis of ovarian torsion with a dermoid cyst. Postoperative pathological examination reported oncocytic and tall columnar type papillary thyroid carcinoma arising on a mature cystic teratoma. During the follow up no local recurrences or metastases were identified in one-year. The rarity of MCT cases undergoing papillary type thyroid carcinoma transformation hinders the establishment of an algorithm for treatment and follow-up in literature.

An efficient biomarker panel for diagnosis of breast cancer using surface-enhanced laser desorption ionization time-of-flight mass spectrometry

Breast cancer (BC) is the most frequently diagnosed cancer that affects women worldwide. Early detection of BC is important to improve survival rates and decrease mortality. The aim of the present study was to investigate serum biomarkers using surface-enhanced laser desorption ionization time-of-flight mass spectrometry (SELDI-TOF-MS) to distinguish patients with BC from the healthy population and patients with benign breast diseases (BBDs). A total of 62 patients with invasive ductal carcinoma, as confirmed by histopathology, and 47 non-cancerous individuals (NCIs) [16 healthy controls (HCs) and 31 patients with BBD] were enrolled in the present study. Serum protein profiles were determined by SELDI-TOF-MS using an immobilized metal affinity capture array. Serum from patients with BC were compared with that from the HC group using univariate and multivariate statistical analyses. A total of 118 clusters were generated from the individual serum. Univariate analysis revealed that 5 peaks were significantly downregulated (m/z 1,452, 2,670, 3,972, 5,354 and 5,523; P<0.001) and 4 were upregulated (m/z 6,850, 7,926, 8,115 and 8,143; P<0.001) in patients with BC compared with the HC group. A comparison of patients with BC and patients with BBD revealed an additional 9 protein peaks. Among these, 3 peaks (m/z 3,972, 5,336 and 11,185) were significantly downregulated and 6 peaks (m/z 4,062, 4,071, 4,609, 6,850, 8,115 and 8,133) were significantly upregulated. A total of 3 peaks [mass-to-change ratio (m/z) 3,972, 6,850 and 8,115 (BC2)] were common in both sets. The results of the present study suggest that a 4 protein peak set [m/z 3,972, 6,850 and 8,115 (BC2) and 8,949 (BC3)] could be used to distinguish patients with BC from NCI.

The prognostic significance of cyclin D1 expression in patients with triple-negative breast cancer

PURPOSE

Breast cancer (BC) is the most common cancer and the second leading cause of cancer death among women. While receptor-targeted therapies are used for other subtypes due to the presence of such receptors, studies are still continuing on receptor expression in order to identify new therapeutic targets as the triple-negative breast cancer (TNBC) lacks a target receptor and its prognosis is worse than the other subtypes. Cyclin D1 (CycD1) is a cell cycle regulator protein. It is stated that its overexpression plays a role in carcinogenesis. With the present study, we aimed to evaluate the prognostic significance of immunohistochemical expression of CycD1 in patients with TNBC.

METHODS

The study included 56 operated patients with TNBC who were diagnosed between 2006 and 2011 at Izmir Katip Celebi University, Ataturk Research and Training Hospital, Department of Pathology. In tumor paraffin-embedded sections, CycD1 was immunohistochemically (IHC) studied. Demographic and survival data of the patients were obtained from the Department of Medical Oncology follow-up files. ROC curve analysis was used to calculate the cutoff value for CycD1 staining density. Patients were divided into two groups using 11.5 cutoff value for the expression of CycD1, obtained by ROC analysis. Kaplan-Meier analysis was utilized for survival analyses, and log rank test for comparisons between the two groups.

RESULTS

Of the patients, 62.5% had CycD1 expression (37.5% had not). In the whole group, the 5-year disease-free survival (DFS) was 51%, and the 5-year overall survival (OS) was 65%. No difference in DFS between the two groups was noticed (p=0.37). The 5-year DFS was 47% in the group with CycD1 expression below 11.5, while it was 57% in the group above the 11.5 value. The difference in OS between the groups was statistically significant (p=0.044). The 5-year OS was 55% in the group with a CycD1 expression below 11.5, while it was 79% in the group above the 11.5 value (p=0.044).

CONCLUSION

OS differed significantly between the high and low-CycD1 expression. It was also demonstrated that CycD1 may have prognostic significance in TNBC. Further studies with larger populations are required to confirm the prognostic significance of CycD1.

Inhibition of Radiation-Induced Oxidative Damage in the Lung Tissue: May Acetylsalicylic Acid Have a Positive Role?

The lung is relatively sensitive to irradiation. It is shown that acetylsalicylic acid (ASA) might reduce oxidative injury and that it has a place in protection from cancer. The aim of this study is to evaluate the potential radioprotective effects of ASA. Whole-body irradiation (6 Gy, single dose) was applied to the rats. Glutathione (GSH), malondialdehyde (MDA), myeloperoxidase (MPO), and nitric oxide (NO) levels in the lung tissue were measured. Control (C), Radiation (R), Radiation + ASA (R + ASA; received irradiation and 25 mg/kg of ASA intraperitoneally (i.p.)), and Radiation + Amifostine (R + WR-2721; received irradiation and 200 mg/kg of WR-2721 i.p.) groups were used. The MPO levels decreased statistically significantly in the group administered ASA. Histopathologically, a radioprotective effect of ASA was more evident in the R + ASA group. ASA is an agent which has not been used as a radioprotector in the clinic yet, and it is worth supporting with more advanced studies.

Association between the ACE gene I/D polymorphism and osteoporosis in a Turkish population

PURPOSE

The purpose of this study was to assess the relationship between osteoporosis and the angiotensin-converting enzyme (ACE) gene insertion/deletion (I/D) polymorphism in a Turkish population.

METHODS

The study group consisted of 238 unrelated women with osteoporosis and 124 unrelated healthy female controls. All participants, patients and healthy controls, were of Turkish origin from the central region of Turkey. Genomic DNA was isolated from whole venous blood samples using a commercial DNA isolation kit. The ACE gene I/D polymorphism was analysed by polymerase chain reaction and gel electrophoresis.

RESULTS

Frequencies of the DD, ID and II genotypes in the patients were 44.5, 41.2 and 14.3 %, and in the controls they were 25.0, 51.6 and 23.4 %, respectively. A significant difference was observed between patients and controls according to genotype frequency (p=0.001). D and I allele frequencies of the I/D polymorphism were 65.1 and 34.9 % in the patient group and 50.8 and 49.2 % in the control group, respectively (p<0.001).

CONCLUSION

The ACE gene I/D polymorphism could be a genetic factor associated with osteoporosis.

The effect of IL-4 and MTHFR gene variants in ankylosing spondylitis

PURPOSE

Ankylosing Spondylitis (AS) is a chronic inflammatory rheumatic disease that characteristically affects the sacroiliac joints and the spine. The exact pathogenesis of AS remains poorly understood, but genetic factors play a key role in disease development. Several genes have been consistently associated with susceptibility to AS. This study was conducted in Turkish AS patients to determine the frequency of the methylenetetrahydrofolate reductase (MTHFR) gene C677T and interleukin-4 (IL-4) gene 70 bp variable number of tandem repeats (VNTR) variants, as well as their association with clinical characteristics.

METHODS

Genomic DNA obtained from 272 persons (122 AS patients and 150 healthy controls) was used in this study. Genomic DNA was isolated and genotyped using a polymerase chain reaction (PCR)-based restriction fragment length polymorphism (RFLP) assay for the MTHFR C677T and IL-4 70 bp VNTR gene variants, which were determined using specific PCR primers.

RESULTS

There was statistically significant difference between the groups with respect to MTHFR genotype distribution (p = 0.02) and allele frequencies (p < 0.001). When we examined MTHFR and IL-4 genotype frequencies according to clinical characteristics, we found an association between the homozygous MTHFR TT genotype and ocular involvement, although this did not reach statistical significance (p = 0.02). However, we did not find any difference between the groups with respect to IL-4 genotype distribution or allele frequencies and clinical characteristics (p > 0.05).

CONCLUSION

Our findings suggest that there is an association of the MTHFR gene C677T polymorphism with the susceptibility of a person for development of AS. However, the IL-4 gene is not associated with AS within the same population.

Hormone receptor, HER2/NEU and EGFR expression in ovarian carcinoma--is here a prognostic phenotype?

PURPOSE

We aimed to evaluate the effects of hormone receptor, HER2, and epidermal growth factor receptor (EGFR) expression on epithelial ovarian cancer (EOC) prognosis and investigate whether or not phenotypic subtypes might exist.

MATERIALS AND METHODS

The medical records of 82 patients who were diagnosed with EOC between 2003 and 2012 and treated by platinum-based chemotherapy were retrospectively evaluated. Expression of EGFR, oestrogen (ER), progesterone (PR), and cerbB2 (HER2) receptors were assessed immunohistochemically on paraffin-embedded tissues of these patients. Three phenotypic subtypes were defined according to ER, PR, and HER2 expression and associations of these with EGFR expression, clinicopathologic features, platinum sensitivity, and survival were investigated.

RESULTS

When we classified EOC patients into three subtypes, 63.4% had hormone receptor positive (HR(+)) (considering breast cancer subtypes, luminal A), 18.3% had triple negative, and 18.3% had HER2(+) disease. EGFR positivity was observed in 37 patients (45.1%) and was significantly more frequent with advanced disease (p=0.013). However, no significant association with other clinicopathologic features and platinum sensitivity was observed. HER2(+) patients had significantly poorer outcomes than HER2(-) counterparts (triple negative and HR positive patients) (p=0.019). Multivariate analysis demonstrated that the strongest risk factor for death was residual disease after primary surgery.

CONCLUSIONS

Triple negative EOC may not be an aggressive phenotype as in breast cancer. The HER2 positive EOC has more aggressive behaviour compared to triple negative and HR(+) phenotypes. EGFR expression is more frequent in advanced tumours, but is not related with poorer outcome. Additional ovarian cancer molecular subtyping using gene expression analysis may provide more reliable data.

Predictive and prognostic factors in locally advanced breast cancer: effect of intratumoral FOXP3+ Tregs

This study aimed to investigate the prognostic and predictive effect of FOXP3+ Tregs together with clinicopathologic factors in locally advanced breast cancer (LABC) patients. The medical records of 101 LABC patients who received neoadjuvant chemotherapy (NAC) between 2005 and 2012 were evaluated retrospectively. The density of intratumoral FOXP3+ lymphocytes in paraffin-embedded tissues was assessed by immunohistochemical analyses in appropriate cases. The relationship with clinicopathologic features, prognosis and chemotherapy response was investigated. HR(-) and HER2(+) tumors tended to have higher pre-chemotherapy Tregs than HR(+) tumors, and significantly higher pathologic complete response (PCR) rates were observed in these patients. Treg decline after NAC was associated with better pathological response rates. Lower intratumoral infiltration of FOXP3+ Tregs after NAC (<3.4/HPF) was significantly associated with higher PCR rates for breast, and close to the significance limit for total (or both for breast and axillary) PCR rates (PCR for breast: 25 vs. 2.9 % for low vs. high Treg, p = 0.001; PCR for breast + axillary tissue: 13.9 vs. 0 %, p = 0.05). Despite better PCR rates, patients with high intratumoral Treg infiltrates (≥11.5/HPF) before chemotherapy had significantly shorter overall survival than patients with low Treg infiltrates (<11.5/HPF). Cox multivariate regression analyses demonstrated that the density of Treg infiltration before chemotherapy was the strongest predictor for survival. This study established the predictive and prognostic effect of intratumoral FOXP3+ Tregs in LABC patients. To predict clinical outcome, evaluation of FOXP3+ Tregs in tumoral tissues before and after NAC should be considered for these high-risk patients.

Pulmonary agenesis and pulmonary sling anomaly in an infant with Down syndrome

Pulmonary agenesis is a rare congenital anomaly presenting with normal karyotype in most of the cases. Rarely pulmonary agenesis is associated with chromosomal abnormalities and other genetic disorders such as Oculo-auriculo-vertebral spectrum, VACTERL association and velo-cardio-facial syndrome. This report presents a patient with pulmonary agenesis, pulmonary sling anomaly and Down syndrome.

Lymphoma of the cervix: A diagnostic pitfall on cervicovaginal smear

Malignant lymphoma that secondarily involves the cervix is a rare condition and may be difficult to distinguish from follicular cervicitis and small cell carcinoma. Cervical lymphoma is sometimes misdiagnosed on cervicovaginal cytology due to its rarity. We report a case of a cervical lymphoma in a 65-year-old woman, which was diagnosed as a squamous cell carcinoma on cervicovaginal cytology.

The clinicopathological significance of Bax and Bcl-2 protein expression with tumor infiltrating lymphocytes in ovarian carcinoma

The aim of the study was to establish the prognostic and predictive value of Bax and Bcl-2 proteins in conjunction with the host immune response in primary epithelial ovarian carcinoma.83 patients were evaluated. Immunohistochemical staining was performed using anti-Bcl-2 (Dako; clone 124) and anti-Bax (Springbio; E17994) monoclonal antibodies. Additionally, the number of lymphocytes within tumor stroma lymphocyte nests were counted. Bcl-2 protein expression was lower in advanced stage than early stage (p= 0.005). High (H) Bax expression was associated with longer overall survival (OS) than lower (L) Bax expression (p=0.03). The OS of the (L) Bax/(L) Bcl-2 group was shorter than (H) Bax/(L) Bcl-2 group in advanced stage (p=0.05). The platinum-sensitive group had a statistically significant tendency for high Bax expression (p=0.04). Furthermore, the intensity of the lymphocyte infiltration was associated with tumor differentiation (p= 0.003). Our data suggests that (H) Bax protein expression prolongs survival, predicts platinum sensitivity and can be used after confirmation of this hypothesis in further prospective studies. The combined evaluation of Bax and Bcl-2 protein expression may provide additional significant prognostic information. The quantity of lymphocyte infiltration could be important for prognostic outcome.

Serum carbohydrate antigen 19-9 levels in patients with unilateral hydronephrosis due to urinary lithiasis

AIM

We aimed to investigate that the association between serum carbohydrate antigen 19-9 (CA 19-9) levels and unilateral hydronephrosis due to urinary lithiasis in homogeneous groups who had no urinary tract infection and renal impairment.

METHODS

A total of 50 patients with ureteral stone enrolled in this study prospectively. The patients were divided into two groups according to degree of hydronephrosis. Patients without hydronephrosis were taken into Group I and who had hydronephrosis were taken into Group II. All patients were underwent treatment of shock wave lithotripsy (SWL). Serum CA 19-9 was measured using immunassay method pre-treatment of SWL. After complete stone clearence and recovery of hydronephrosis in all patients, patiens were re-evaluated and CA 19-9 levels were measured.

RESULTS

There were no significant differences for age, gender, body mass index, stone volume, shock wave number, number of SWL seasons, and serum creatinin between the groups (P>0.05). Pre-SWL serum mean Ca 19-9 levels were 14.82±14.64 U/mL. in Group I and 13.89±13.03 U/mL. in Group II (P=0.8686). After complete stone clearance and recovery of hydronephosis with SWL, the mean CA 19-9 values were measured as 14.14±10.67 U/mL. in Group II and there were not found significant change as compared pre-SWL values for Group II (P=0.7334).

CONCLUSION

The relationship between CA 19-9 values and hydronephrosis was not found to be statistically meaningful on the contrary to previous reports and it does not appear as a useful parameter to predict of urinary obstruction non-invasively.

The clinicopathological evaluation of the breast cancer patients with brain metastases: predictors of survival

We aimed to define the clinicopathologic characteristics of breast cancer (BC) patients with brain metastasis (BM) and to investigate the effect of these parameters on survival. Seventy-nine patients diagnosed with BC and symptomatic BM between 1995 and 2011 were retrospectively evaluated. The relationship between clinicopathological features and outcome was investigated. Triple negative patients had the shortest overall survival (OS) while HR(+)HER2(-) patients had the longest (48.2  vs 88.2 months, 95 % CI; p = 0.33). Multivariate analysis demonstrated that luminal A subtype was the strongest positive predictor of prolonged OS (HR 0.48, 95 % CI 0.28-0.84; p = 0.01), while poor performance status (PS) (ECOG 3-4) at BM was the strongest predictor of shortened OS (HR 1.92, 95 % CI 1.21-3.06; p = 0.006). The patients with early-stage BC at diagnosis had BM later than the advanced-staged patients (47 months for Stage I-II disease, 23.2 months for Stage III-IV disease, 95 % CI; p = 0.002). Median survival after BM was 10.2 months (6.4-14 months, 95 % CI). The patients with liver or skin metastases had significantly shorter survival than the patients with only BM (4.8 vs 17 months, p < 0.001 for liver and 4.8 vs 11.1 months, p = 0.04 for skin). Multivariate analysis demonstrated that regardless of the BC subtype, lack of systemic therapy, and liver involvement were independent factors associated with increased risk of death (HR 4, 95 % CI 1.7-9.1; p = 0.001 and HR 2.2, 95 % CI 1.05-4.9; p = 0.036 respectively). Clinical outcome after BM mostly depends on the ECOG PS and the fact that whether the patient received systemic therapy or not. Systemic therapy prolongs survival especially in HER2 positive patients.

Cancer in elderly: A study of hospital-based cancer registry in the Western Turkey

AIM

The aim of the study is to evaluate the data of cases who were 65 years and older among cancer records from the data of Izmir Cancer Registry (ICR), in Izmir Ataturk Research Training Hospital (IAEAH), according to topography, histology, sex and having multiple tumors and to compare them with the data of cases younger than 65 years.

MATERIAL AND METHODS

Twenty thousands eight hundred and thirty (20,830) cases (7148 cases are ≥65 years) recorded during the period of 1993-2005 by office of ICR, located in IAEAH, were analyzed. Assessment of data was carried out by SPSS 10.0 for Windows package program. For statistical analysis Pearson's Chi-Square Test and Yates 'corrections were performed.

RESULTS

Of 20,830 cases with cancer, recorded in the hospital data-base during 1993-2005, 34.3% were diagnosed at the age of 65 years and older. The most frequent tumor localizations in the cases younger than 65 years were breast, larynx, digestive system, skin and hematopoietic-reticuloendothelial system whereas the tumors in the, skin, digestive system and the urogenital system were more common in cases older than 65 years. When histological diagnoses were taken into consideration, basal cell carcinomas and squamous and transitional cell carcinoma were seen more frequent in the group of cases 65 years or older. The incidence of synchronous and metachronous tumors were not different in the cases younger or older than 65 years.

CONCLUSION

There is a strong need to establish a communication between national and international database systems, which would yield an opportunity in the comparison of the incidence of the diseases.

Evaluation of endometrium by transvaginal ultrasonography and Doppler in tamoxifen-treated women with breast cancer

PURPOSE

The purpose of this study was to investigate the discriminative role of transvaginal ultrasonography and Doppler measurements on the detection of endometrial pathologies in tamoxifen-treated breast cancer patients.

METHODS

Tamoxifen-treated breast cancer patients were included in this prospective study between February 2009 and June 2010. The subjects were assessed by gynecologic examination and transvaginal gray-scale and Doppler sonography. The patients whose endometrial thicknesses were more than 6 mm underwent endocervical/endometrial curettage for histopathological examination.

RESULTS

There were 98 tamoxifen-treated patients with breast cancer enrolled in the study, providing 141 ultrasound evaluations. Uterine artery pulsatility index was significantly lower in postmenopausal than premenopausal patients (p: 0.013). Endocervical and endometrial curettage was performed in 52 patients. It was more prevalent that the endometrial strip was > or = 6 mm in women with abnormal endometrial histopathology (p: 0.020). However the women with abnormal endometrial histopathology presented lower vascular indices; the only significant difference was in myometrial pulsatility index (p: 0.036).

CONCLUSION

The most evident tool for evaluating the endometrium in tamoxifen-treated breast cancer patients is still the transvaginal measurement of its thickness. It exists that Doppler ultrasonographic assessment of uterine, radial and spiral vasculature has no additional benefit for detection of endometrial pathology.

Treatment of cadmium and nickel electroplating rinse water by electrocoagulation

Treatments of cadmium-cyanide and nickel-cyanide electroplating rinse water were investigated in an electrochemical reactor equipped with iron plate electrodes in a batch mode by electrocoagulation (EC). Effects of the process variables such as pH, current density, and operating time were explored with respect to removal efficiencies of cadmium, nickel and cyanide in electroplating rinse water and operating costs as well. Removal efficiencies and operating costs under the optimum conditions (30 A/m2, 30 min and pH 8-10 for cadmium; 60A/m2, 80 min and pH 8-10 for nickel) for the EC process in electroplating rinse water were determined as 99.4% and 1.05/m3 for cadmium, 99.1% and 2.45/m3 for nickel and > 99.7% for cyanide, respectively. The results indicated that EC was very effective treatment for the removals of cadmium, nickel, and cyanide ions from the electroplating rinse water.

Periodontal disease in patients with familial Mediterranean fever: from inflammation to amyloidosis

BACKGROUND AND OBJECTIVE

Familial Mediterranean fever stimulates a very intense acute-phase reactants response and if left untreated eventually leads to amyloidosis. The aim of this study was to determine the prevalence of periodontal disease among patients with familial Mediterranean fever in the Black Sea region in Turkey and to evaluate whether periodontitis is related to amyloidosis in patients with familial Mediterranean fever.

MATERIAL AND METHODS

One-hundred and thirty three patients with familial Mediterranean fever and 50 healthy subjects were included in this study. Periodontal health and disease were evaluated using the gingival index, papillary bleeding index, plaque index and periodontal disease index. The concentrations of serum acute-phase reactants were measured at baseline and at 4-6 wk after completion of the nonsurgical periodontal therapy. Genetic testing for familial Mediterranean fever was performed using the familial Mediterranean fever StripAssay. Kidney biopsy was carried out on all proteinuric patients.

RESULTS

The prevalence of moderate to severe periodontitis in familial Mediterranean fever patients with amyloidosis (80.6%) was significantly greater (p < 0.01) than in familial Mediterranean fever patients without amyloidosis (38%) and in controls (20%). Serum levels of acute-phase reactants in familial Mediterranean fever patients were reduced significantly following nonsurgical periodontal therapy (p < 0.01).

CONCLUSION

Periodontal therapy seems to reduce the serum levels of acute-phase reactants in patients with familial Mediterranean fever. Therefore, treating periodontitis might help to alleviate the disease burden in patients with familial Mediterranean fever.

The impact of individual room on rehospitalization and health service utilization in preterms after discharge

AIM

To compare individual room implemented family-centred care to classical designed neonatal intensive care unit and find out its effect on rehospitalization and application to health services in preterm infants after discharge.

METHODS

Mothers whose infants were born before 34 gestational weeks and hospitalized for at least one week in the NICU were enrolled in the study. Mothers who were hospitalized with their preterm infants in individual rooms (Group I) were compared with mothers who were not hospitalized with their preterm infants (Group II). After the third postdischarge month, groups were compared for their rates of phone consultations to physician/hospital, acute care applications, rehospitalization and parent's perception of child's vulnerability.

RESULTS

Although demographic and medical information did not indicate any differences between the groups, the mean number of acute care visits (p = 0.046), the median number of phone consultations (p = 0.001) and rehospitalization rate (12.9% vs. 34.5%, p < 0.05) were significantly higher in Group II. The anatomical problems, such as inguinal hernia and retinopathy of prematurity, were the main recorded causes in Group I whereas problems related to prematurity like feeding difficulties were dominating in Group II.

CONCLUSION

The availability of individual rooms that allows maternal presence and participation during the hospitalization of the mother's preterm infant, is correlated with lower rates of rehospitalization and healthcare applications.

Advanced stage of cervical carcinoma undiagnosed during antenatal period in term pregnancy and concomitant metastasis on episiotomy scar during delivery: a case report and review of the literature

The objective of this study is to review the implantation of malignant cells of cervical cancer in an episiotomy site. This is the second case of cervical cancer with concomitant episiotomy metastasis in the literature. The treatment consisted of radiochemotherapy. There was no confirmed recurrent disease after 1 year of follow-up in our reported case. In conclusion, pregnancy appears to be a chance for cervical cancer screening as a part of prenatal care. If cervical cancer is diagnosed in a woman after vaginal delivery, she must be examined carefully including the episiotomy site.

A case with three different synchronous primaries of the female genital system and their treatment

Multiple carcinomas of the genital system are rare in the literature. We report a 43-year-old female patient who presented with 3 different synchronous primary genital system malignancies (cervix, endometrium and ovary). After Wertheim's hysterectomy there was a 4 x 2 cm residual mass for which systemic chemotherapy and radiotherapy were administered. The patient rapidly deteriorated and died due to disease progression. Registration of cases with multiple tumors in a single centre using a standardized investigation for predisposing parameters may contribute much to the management of such conditions.

[Thick-needle vacuum-assisted biopsy technique for inflammatory breast carcinoma diagnosis]

PURPOSE

Inflammatory breast carcinoma (IBC) is a rare clinicopathological cancer type with unique clinical features and a poor prognosis. In this disease, there is generally no palpable mass in the breast. IBC can be mistakenly diagnosed as mastitis and patients may receive a delayed diagnosis and treatment, since these two disorders cause similar pathological appearences on the breast. Clinical suspicion of the disease followed by histopathological observation of occluded dermal lympthatics by tumor emboli leads to definitive diagnosis of IBC.

METHODS

Here, we report our experiences in diagnosing IBC using Thick-Needle Aspiration Biopsy (TNAB).

RESULTS

Eight patients having clinically suspected IBC, received TNAB. IBC was definitively diagnosed upon observation in histopathological examination of occluded dermal lymphatics by tumor emboli since TNAB allowed adequate tissue sampling.

CONCLUSION

In this study, we showed that IBC can be reliably diagnosed using TNAB.

Uterine tumor resembling ovarian sex cord tumors in a patient using tamoxifen: report of a case and review of literature

Increasing number of uterine malignancies have been reported in breast cancer patients using tamoxifen. Most of these are endometrial adenocarcinomas. However, only a few cases of endometrial stromal sarcomas have been reported to be linked with tamoxifen usage. A 58-year-old postmenopausal women who had been using tamoxifen for 4 years after a surgery for breast cancer is presented with chronic pelvic pain. Preoperative investigations were indicative of a uterine myoma so that a standard total abdominal hysterectomy and bilateral salpingo-oophorectomy were performed. Postoperative histologic diagnosis was a uterine tumor resembling ovarian sex cord tumors, which is an exceedingly rare entity itself. The present case is the first designated diagnosis of this rare tumor, with a possible association of tamoxifen usage.

Comparison of underlying lesions in pediatric and adult ovarian torsion

OBJECTIVE

To compare the pediatric and adult ovarian torsion and explore a quantitative value to predict a possible underlying tumor.

METHODS

This study included 32 pediatric and 33 adult female cases diagnosed with ovarian torsion and underwent surgical treatment in Dr. Behcet Uz Children's Research Hospital and Ataturk Education and Research Hospital, Izmir, Turkey between 1989 and 2005. We evaluated the properties of the cases statistically.

RESULTS

The mean age of pediatric was 8 years and 3 months and adult cases was 39 years and 8 months. Six cases had an underlying tumor in both pediatric and adult group. The mean diameter and volume difference were 6.84 cm, 91 cc in pediatric and 12.69 cm and 1087 cc in the adult group. In statistical analysis, the diameter and volume increase were significantly higher in cases with underlying tumor in pediatric group. The cut-off value was 7 cm in diameter and 104 cc in volume increase. In the adult group, the diameter and volume increase were not significant in tumor positive and negative group.

CONCLUSION

Torsion of the ovary requiring surgery, is rare and is the mot common reason of abdominal/pelvic mass. These cases are often difficult to decide for surgical procedure especially in pediatric cases. We conclude that an underlying lesion more commonly occurs in children with an increase in ovarian volume of more than 104 cc and a diameter more than 7 cm. Great care should be taken for laparoscopic conservative management especially in these cases. The quantitative analysis is not predictive for the underlying solid lesion in adult cases.

Whole blood versus red cells and plasma for exchange transfusion in ABO haemolytic disease

Records of 381 neonates who underwent exchange transfusion (ET) due to ABO haemolytic disease at the Division of Neonatology of Hacettepe University, Ankara, Turkey, between January 1977 and December 2003 were reviewed. Records were kept for the type of blood used in ET, the number of ETs for each infant, adverse event attributable to ET and bilirubin levels before, and 4 and 8 h after each ET. Of 381 infants, 300 were transfused with whole blood, whereas 81 infants were transfused with O red cells suspended in A or B plasma. The re-exchange rate was higher in the whole blood group, compared with the erythrocyte and plasma group. Use of erythrocyte and plasma provided 30% reduction in the number of ETs per patient. Eight hours after the first ET, mean bilirubin levels were 84% of the pre-exchange values in the whole blood group and 73% of the pre-exchange values in the erythrocyte and plasma group (P = 0.001). As the use of O group red cells re-suspended in AB plasma decreased the re-exchange risk compared with O group whole blood, we suggest the use of O red cells re-suspended in AB plasma for the ET in cases of ABO haemolytic disease.

Adenosarcoma of the uterus: a case report

Accuracy of frozen section diagnosis in ovarian tumors: Is there a change in the course of time?

A retrospective study of 222 ovarian biopsy results between January 1, 2000 and August 31, 2002 was examined to determine the accuracy of frozen section diagnosis. In addition we reviewed all previous studies that examined the accuracy rates of frozen section diagnosis in ovarian tumors. Histopathologic examination results of frozen section biopsies were concordant with paraffin diagnosis in 92% of all cases. The sensitivity rates for benign, malignant, and borderline ovarian tumors were 98%, 88.7%, and 61%, respectively. There were five (2.2%) false-positive (overdiagnosed), and 13 (5.4%) false-negative (underdiagnosed) patients in frozen section examination. Frozen section examination of mucinous tumors showed higher underdiagnosis rates (20%). Review of previous studies showed no significant variation in accuracy rates of frozen section diagnosis for benign and malignant ovarian tumors, in relation with time. We found low accuracy rates for borderline ovarian tumors which was similar with the previous studies. However, there were consistent and relatively higher sensitivity rates for borderline ovarian tumors in the recent studies. As a result, we conclude that frozen section evaluation in identifying a malignant or benign ovarian tumor is accurate enough for the correct diagnosis. Since accuracy rates for borderline ovarian tumors are low, we should have more improvement in the correct diagnosis.

Endothelin 1 concentrations in infants with meconium stained amniotic fluid

Plasma endothelin 1 concentrations were determined in infants with meconium stained amniotic fluid. Plasma endothelin 1 concentration in the study group (5.23 pg/ml) was statistically higher than that in the control group (1.12 pg/ml). Cord blood pH and base excess values were significantly lower in infants with meconium stained amniotic fluid when compared with the control group. There was no correlation between endothelin 1 concentrations and pH or base excess values. Results suggest that meconium passage is not a physiological event, even if meconium stained infants appear to be clinically healthy.
