Abstract
Nature-based solutions such as constructed wetlands (CW) are considered as a sustainable, green technology for greywater treatment. However, their efficiency to remove microplastics is not well-known even though greywater is considered as a significant source of microfiber pollution. In this study, the removal of fiber microplastics from greywater using a vertical flow constructed wetland (VFCW) was investigated. For the purposes of this study, an experimental wetland was constructed, planted with the flowering plant Zantedeschia aethiopica and filled with a substrate made of sand/gravel of several sizes. The system's performance was monitored for five months during which it received real laundry wastewater. Promising results were obtained showing the significant removal of microfibers from the influent (> 95 %). Moreover, the ability of the system to remove microfibers from laundry wastewater was not significantly affected from the hydraulic loading rate (HLR) applied. The average microfibers concentration decreased from 71 ± 25 microparticles/L in the influent to 1 ± 1 microparticles/L in the effluent of VFCW when an HLR of 63.7 mm/d was applied. High removal efficiencies were also observed for COD and turbidity (93 % and 94 %, respectively). Thus, the results indicate a significant improvement in the overall quality of laundry wastewater due to the use of the VFCW.

Abstract
Abstract
Background - aim: Information on the prognostic role of cytotoxic CD8+ T cells in the era of modern adjuvant CT is limited. The primary objective of the present report is to assess the prognostic impact of CD8+ cells in patients with intermediate or high-risk EBC (T1-3N1-2M0) treated with dds-CT. Secondary endpoints are safety, disease-free survival (DFS) and overall survival (OS).
Patients and Methods: Patients (N=1,000) were treated with 4 cycles of Epirubicin, 75mg/m2, and Cyclophophamide, 600mg/m2 every 2 weeks followed by 4 cycles of Docetaxel (D), 100mg/m2 every 3 weeks with G-CSF support in all cycles. Trastuzumab was initiated concurrently with D and continued for a total of 1 year. Hormonal and radiation therapy were given post CT, as indicated. Formalin-fixed paraffin-embedded tumors were available for 642 patients (64.2%) and were centrally assessed for immunohistochemical subtypes (IHC4; N=526), stromal TILs density by morphology (N=636), as well as stromal and intratumoral cytotoxic CD8+ T cell numbers (N=554). TILs and CD8+ were assessed as continuous variables for associations and as 10% increments for outcome.
Results: In total, 901/1,000 pts (90.1%) completed 8 cycles of CT. Severe (gradeIII-IV) toxicitiesincludedneutropenia (5.6%), leucopenia (3.6%), lymphopenia (2.1%), hand-footsyndrome (2.1%), and hepatotoxicity (1.8%). Febrileneutropenia occurred in 1.6% of the patients. The 5-year DFS and OS rates were 89.5% and 93.1%, respectively. Luminal A tumors were classified in 26.2%, Luminal B in 35.2%, luminal HER2 in 9.5%; HER2-enriched in 7.2%; and, triple-negative (TNBC) in 21.9% of informative patients. Among subtypes, stromal TILs density was higher in HER2-enriched and TNBC (p<0.001); intratumoral CD8+ values were higher in TNBC (p<0.001); and, stromal CD8+ were higher in HER2-enriched (p=0.034). In all patients, TILs density and intratumoral CD8+ cell numbers were not associated with DFS and OS, while increased stromal CD8+ were marginally associated with prolonged DFS (HR=0.98, 95%CI 0.96-1.00, p=0.066).Adjusted for histological grade, menopausal, ER/PgR and nodal status, higher stromal CD8+ were associated with prolonged DFS (HR=0.98, 95% CI 0.96-1.00, p=0.043). In TNBC, higher stromal TILs density conferred prolonged DFS (HR=0.97, 95%CI 0.94-0.99, p=0.029), which retained its prognostic significance in multivariate analysis (HR=0.97, 95% CI 0.94-1.00, p=0.049).
Conclusions: In this study, dds-CT was well tolerated and active in patients with EBC. We confirm the presence of morphologically assessed higher TILs density, and of higher cytotoxic CD8+ T cell numbers in hormone receptor negative EBC, as well as the favorable prognostic impact of higher stromal TILs density in TNBC. In comparison to stromal TILs density, higher stromal CD8+ may confer favorable prognosis irrespectively of EBC subtype. Stromal CD8+ seems to be a marker worth further standardizing for reporting on immune cell infiltrates in EBC.

Abstract
Abstract
Background-Aim: Breast cancer is a heterogeneous disease and despite recent scientific progress there is still need for the identification of biomarkers associated with risk for relapse, as well as for markers identifying patients who will benefit from specific treatments. The aim of the present study was to investigate the role of MYC, as a clinically meaningful biomarker, in the outcome of breast cancer subtypes.
Patients and Methods: We have pooled the patients and the respective breast carcinomas from two randomized anthracycline-based adjuvant phase III trials, consecutively conducted by the Hellenic Cooperative Oncology Group (HE10/97 and HE10/00). The HE10/97 trial included a non-paclitaxel arm. Tissue microarrays were constructed from 1,060 formalin-fixed paraffin-embedded tumor tissue samples that were collected retrospectively in the first and prospectively in the second trial. MYC was evaluated by immunohistochemistry (IHC) and fluorescence in situ hybridization (FISH) in 986 cases.
Results: In total 61.0% of the cases showed positive cytoplasmic MYC immunostaining, while 26.5% showed positive nuclear staining. 65-80% of the patients were characterized as non-amplified or loss/normal-low gain in all FISH cut-offs examined. A weak association was observed between FISH and nuclear protein expression of MYC. High histological grade was associated with MYC protein overexpression and gene amplification. In terms of disease-free survival (DFS), low (2.5-5 copies) and high (≥5 copies) gain of MYC was of adverse prognostic value compared to loss/normal (<2.5 copies) MYC (HR=1.50, 95% CI 1.13-1.98, Wald's p=0.004 and HR=1.45, 95% CI 1.07-1.97, p=0.016, respectively). Comparable results were observed for overall survival (OS) (HR=1.51, 95% CI 1.09-2.08, p=0.013 and HR=1.65, 95% CI 1.17-2.33, p=0.005, respectively). The comparison of neoplasms with CEP8 ratio ≥1.3 and polysomy 8 for MYC versus all others resulted in worse survival prognosis (HR=1.44, 95% CI 1.13-1.83, p=0.004), while tumors with nuclear protein overexpression were associated with better DFS (HR=0.77, 95% CI 0.60-0.99, p=0.039) and OS (HR=0.73, 95% CI 0.55-0.98, p=0.034). In HER2-enriched patients, MYC amplification was found to be an adverse prognostic factor for DFS (HR=2.11, 95% CI 1.09-4.07, p=0.026) and OS (HR=2.41, 95% CI 1.12-5.15, p=0.024).
Treatment with paclitaxel was found to differentiate the effect of MYC: CEP8 ratio ≥1.3 and polysomy 8 in terms of DFS and OS in our total cohort. Among patients with CEP8 ratio ≥1.3 and polysomy 8, those treated with paclitaxel performed significantly better than those not treated, while among patients not treated with paclitaxel, those with CEP8 ratio ≥1.3 and polysomy 8 performed much worse than those with CEP8 ratio <1.3 or no polysomy 8.
Conclusions: Our data suggest that MYC has prognostic and predictive value in patients with breast cancer. MYC amplification and MYC protein overexpression are detected in breast cancer patients and are of adverse prognostic value for DFS and OS. Polysomy 8 is also associated with worse prognosis. Treatment with paclitaxel in the adjuvant setting benefits breast cancer patients with MYC:CEP8 ratio ≥1.3 and polysomy 8.

Abstract
As a result of the nuclear accident in Fukushima Dai-ichi power plant, which started on March 11, 2011, radioactive pollutants were transferred by air masses to various regions of the Northern hemisphere, including Europe. Very low concentrations of (131)I, (137)Cs and (134)Cs in airborne particulate matter were measured in Athens, Greece during the period of March 24 to April 28, 2011. The maximum air concentration of (131)I was measured on April 6, 2011 and equaled 490 ± 35 μBq m(-3). The maximum values of the two cesium isotopes were measured on the same day and equaled 180 ± 40 μBq m(-3) for (137)Cs and 160 ± 30 μBq m(-3) for (134)Cs. The average activity ratio of (131)I/(137)Cs in air was 3.0 ± 0.5, while the corresponding ratio of (137)Cs/(134)Cs equaled 1.1 ± 0.3. No artificial radionuclides could be detected in air after April 28, 2011. Traces of (131)I as a result of radioactive deposition were measured in grass, soil, sheep milk and meat. The total deposition of (131)I (dry + wet) was 34 ± 4 Bq m(-2), and of (137)Cs was less than 10 Bq m(-2). The maximum concentration of (131)I in grass was 2.1 ± 0.4 Bg kg(-1), while (134)Cs was not detected. The maximum concentrations of (131)I and (137)Cs in sheep milk were 1.7 ± 0.16 Bq kg(-1) and 0.6 ± 0.12 Bq kg(-1) respectively. Concentrations of (131)I up to 1.3 ± 0.2 Bq kg(-1) were measured in sheep meat. Traces of (131)I were found in a number of soil samples. The radiological impact of the Fukushima nuclear accident in Athens region was practically negligible, especially as compared to that of the Chernobyl accident and also to that of natural radioactivity.

Abstract
The vertical distribution of natural radionuclides ((232)Th decay, (238)U decay, (40)K and (210)Pb) was assessed in sediment cores collected from the Amvrakikos Gulf, (Ionian Sea, Western Greece). Two collection stations were selected, the first at the western part of the Gulf near Preveza Strait (13A station) and the other near the centre of the Gulf (13B station). Activity concentrations were measured by means of gamma-ray spectrometry using high-purity germanium (HPGe) detectors installed at two national laboratories. The activity concentration of (226)Ra was found in a range from 10 to 20 Bq kg(-1), while the activity concentration of (222)Rn daughters ((214)Pb, (214)Bi) ranged from 6 to 20 Bq kg(-1). The activity concentration of (228)Ac varied from 20 to 28 Bq kg(-1), while (220)Rn daughters ((212)Pb, (208)Tl) from 7 to 35 Bq kg(-1). As concerns (40)K and (210)Pb, their activities varied from 400 to 830 Bq kg(-1) and from 11 to 360 Bq kg(-1), respectively. Also, the data of (210)Pb were utilised in the calculations of the sedimentation rate along the sediment cores. Both locations were characterised by a consistent pattern with the average rates of 0.55 ± 0.02 and 0.32 ± 0.02 cm y(-1), corresponding to 13A and 13B stations, respectively. Finally, the measurements constituted the basis of the first reported database concerning the radiological condition of the Gulf and which can be reclaimed as reference values in future monitoring studies.

Abstract
AIM Ovarian carcinomas have been classified into types I and II according to the hypothesised mode of carcinogenesis and molecular characteristics. The prognostic significance of this classification has not been studied. PATIENTS AND METHODS Five hundred and sixty-eight patients with histologically confirmed, ovarian, fallopian tube or peritoneal carcinomas, international federation of gynecology and obstetrics (FIGO) stages IIC-IV, treated with paclitaxel/platinum following cytoreductive surgery, were included in this analysis. Type I included low-grade serous, mucinous, endometrioid and clear-cell and type II high-grade serous, unspecified adenocarcinomas and undifferentiated carcinomas. RESULTS Median overall survival (OS) was 49 months for type I versus 45 for type II (p=0.576). In contrast to type II, there was considerable prognostic heterogeneity among the subtypes included in type I. Cox regression analysis showed that cell-type classification: low-grade serous, mucinous, endometrioid, clear-cell, type II (high-grade serous, unspecified adenocarcinomas, undifferentiated carcinoma) was an independent predictor of survival (respective median OS 121 versus 15 versus 64 versus 29 versus 45 months, p=0.003). On the contrary, histopathological subtype or tumour type (I versus II) did not offer additional prognostic information. CONCLUSION The proposed model of ovarian tumourigenesis does not reflect tumour behaviour in advanced disease. Tumour-cell type is the most relevant histopathological prognostic factor in advanced ovarian cancer treated with platinum/paclitaxel.

Abstract
BACKGROUND Multiple endocrine neoplasia (MEN) IIb is a rare genetic syndrome characterized by the occurrence of medullary thyroid carcinoma (MTC), pheochromocytoma and mucosal neuromas. CASE REPORT A 43-year-old woman with MEN IIb syndrome presented to our department with a painful enlargement of the left side of her vulva, which was initially presumed to be an inflammatory Bartholin's gland process. Upon admission, the patient was on antibiotics with no response and surgery was decided. A wide local excision was performed and histology revealed a metastatic medullary carcinoma of the vulva. CONCLUSION MEN IIb syndrome is a clinical entity that may present multiple metastatic sites. To our knowledge, this is the first case of vulvar metastasis as part of the syndrome.

Abstract
We report a case of a 24-year-old female who underwent laparoscopy for a presumed benign ovarian mass. Frozen sections at laparoscopy initially revealed a borderline papillary serous ovarian tumour. Final histology showed an invasive papillary serous ovarian tumor (grade 1). Subsequent staging laparotomy conducted 13 days later revealed peritoneal implantations thus upgrading the initially thought Stage Ia papillary serous ovarian tumour at laparoscopy to Stage IIc. The patient after laparotomy had an uneventful postoperative course and received six cycles of chemotherapy based on taxol and carboplatin. A short review of the literature is also presented, concerning the factors which affect the patient's prognosis in cases of unexpected ovarian malignancy found during laparoscopy that are treated with subsequent staging laparotomy.

Abstract
PURPOSE To assess the prognostic and predictive significance of p53 and Bcl-2 protein expression in high risk patients with breast cancer treated with dose-dense sequential chemotherapy. PATIENTS AND METHODS From June 1997 until November 2000, 595 patients were randomized to three cycles of epirubicin (E) 110 mg/m2 followed by three cycles of paclitaxel (P) 250 mg/m2 followed by three cycles of 'intensified' CMF (cyclophosphamide 840 mg/m2, methotrexate 47 mg/m2 and fluorouracil 840 mg/m2) or to four cycles of E, followed by four cycles of CMF. p53 and Bcl-2 expression was investigated by immunohistochemistry in 392 and 397 patients respectively. RESULTS Positive expression of p53 was detected in 104 (26.5%) patients and was significantly associated with negative hormonal status, worse histologic grade, higher incidence of disease relapse and higher rate of death. p53 positive expression was a significant negative predictor of overall survival (OS) (P = 0.002) and disease-free survival (DFS) (P = 0.001). Negative expression of Bcl-2 was detected in 203 (51%) patients and was significantly associated with negative hormonal status. Multivariate analysis revealed that, positive p53 expression, higher number of positive nodes and worse tumor grade were related to significantly poorer OS and DFS. CONCLUSIONS For both treatments, p53 positive expression was a significant negative prognostic factor for OS and DFS while Bcl-2 was not. No predictive ability of p53 status or Bcl-2 status for paclitaxel treatment was evident.

Abstract
Neovascularization is a critical step in the growth, progression and metastasis of tumors. The degree of angiogenesis may correlate with disease stage and provide prognostic information in various neoplasms. Microvessel density was studied in 24 patients with severe cervical intraepithelial neoplasias, 15 patients with microinvasive carcinomas (International Federation of Gynecology and Obstetrics IA1) and 15 healthy controls who had undergone hysterectomy for benign conditions. The microvessel density (MVD) in microinvasive squamous cell carcinomas was 40 +/- 2.42 (mean +/- SD) and in squamous carcinomas in situ (CIS) 20.41 +/- 2.29 (p < 0.05). Among patients with CIS and controls (13.33 +/- 1.59) there was also a significant difference in the number of vessels (p < 0.05). No significant correlation was found in relation to depth of invasion and histological grade of the microinvasive carcinomas. It is concluded that microinvasive squamous cell cervical carcinoma is an angiogenetic disorder and it seems that the onset of angiogenesis is an early event, usually in a preinvasive stage.

Abstract
Malignant rhabdoid tumors of the vulva are rare neoplasms which most of the time show aggressive behavior and a dismal prognosis. We report a case of malignant rhabdoid tumor of the clitoris occurring in an elderly patient. Due to the similarities that these neoplasms show with other low-differentiated tumors, immunohistochemical and ultrastructural assessment should always be conducted so that accurate diagnosis is achieved. Individualized extensive surgical treatment might decrease relapsing disease.

Abstract
Cat-scratch disease (CSD) may appear as a solitary mass in the breast and give the impression of a breast carcinoma. In this case, further clinical and laboratory investigation is required to rule out malignancy. We present three cases of CSD of the breast in women of 64, 31 and 61 years old. Each presented with enlarged lymph-nodes in the breast, which were clinically mistaken for solitary tumours. In the first two patients, the mammography was negative. The third patient had a mammogram which indicated a well-defined solid mass in the parenchyma without calcifications. We discuss the clinical, histological and histochemical findings, analyze the differential diagnosis and review the literature.

INTRODUCTION Intravenous leiomyomatosis (IVL) is rare and it is characterized by intravascular nodular masses of histologically benign smooth muscle that may extend variable distances. Although histologically benign, IVL might be malignant in its mode of behavior. CASE REPORT AND DISCUSSION A case of IVL is reported with emphasis on immunohistochemical analysis and recent literature.

Abstract
Disorders of sexual differentiation are usually diagnosed at an early age. We hereby describe a case of a 29-year-old phenotypic woman who during the evaluation of amenorrhea was found to have a 46, XY karyotype. Further evaluation (including laparoscopy) suggested that she presented a variant of gonadal dysgenesis, with the particularity of having well-developed müllerian structures and testicular remnants alongside a steroid-producing gonadoblastoma.

Abstract
This study was performed to investigate the relationship between histological type and grade, with the uptake and washout of 99mTc-hexakis-2-methoxyisobutylisonitrile (99mTc-sestamibi, 99mTc-MIBI) and 99mTcV-dimercaptosuccinic acid (99mTcV-DMSA) in breast cancer. Forty-five patients with histologically proven breast cancer had previously been referred for 99mTcV-DMSA and/or 99mTc-MIBI scintimammography. Twenty-five of them underwent both 99mTcV-DMSA and 99mTc-MIBI scintigraphy in a double phase study. Lateral prone and anterior supine images were acquired at 15 and 60 min after administration of 740-925 MBq of each radiotracer. Uptake ratios and retention index were calculated and correlated with histology and grade of malignancy. Histology showed eight different histotypes: 77.7% were infiltrating ductal or lobular carcinomas. Mammography was definitely positive in 32/45, indeterminate in 10 and negative in three cases (sensitivity 71%). 99mTcV-DMSA was true positive in 37/40 (sensitivity 92.5%) and 99mTc-MIBI in 28/30 (sensitivity 93.3%) breast cancers. Uptake ratios were significantly higher in ductal than in lobular carcinomas on 99mTcV-DMSA and 99mTc-MIBI scintigrams at early and delayed phases. Grade II carcinomas had significantly lower values of retention index (rapid washout) than grade III carcinomas. This finding was statistically significant only on 99mTc-MIBI scans and was observed in ductal and lobular carcinomas. The retention index did not show any significant difference between ductal and lobular carcinomas. Uptake ratios were also not statistically different between grade II and III cancers. It is concluded that 99mTc-MIBI and 99mTcV-DMSA uptake in breast cancer is probably related to histological type and may distinguish ductal from lobular carcinomas. To a certain degree, the washout rate may reflect the histological grade, but since grade is not the only factor influencing this phenomenon it should be explored further in conjunction with other parameters by multivariate analysis in order to clarify eventual indirect correlations.

Abstract
Primary squamous cell carcinoma of the endometrium (PSCCE) is a rare disease of unknown etiology. Diagnosis is based on the identification of squamous cell carcinoma in the endometrium with no coexisting analogous cervical component or endometrial adenocarcinoma. There must also be no connection between the endometrial tumour and the squamous epithelium of the cervix. Although the majority of patients are classified as stage I disease, prognosis is rather dismal. We report two new cases of primary squamous cell carcinoma of the endometrium which fulfill all the above criteria and we discuss another interesting case of squamous cell carcinoma of questionable endometrial origin. Management by abdominal hysterectomy and adjuvant pelvic irradiation resulted in long-term survival of our patients.

Abstract
The purpose of this study was to evaluate and compare the diagnostic accuracy of pentavalent technetium-99m dimercaptosuccinic acid [99mTc-(V)DMSA] and 99mTc-methoxyisobutylisonitrile (MIBI) in the detection of primary breast cancer and metastatic lymph node involvement, and in the clarification of cases with indeterminate mammograms. Forty-one women (mean age+/-SD 55+/-7 years) referred for a suspicious breast lesion on physical examination and/or an abnormal mammogram underwent MIBI and (V)DMSA scintimammography (SMM) at separate sessions (48-h interval). Lateral prone and anterior supine images were obtained at 10 and 60 min after administration of 740-925 MBq of each tracer, in the arm contralateral to the breast lesion. The ipsilateral axillary region was also included in the field of view. The results of SMM and mammography were compared with histological findings. Breast cancer was histologically confirmed in 26 patients (mean diameter+/-SD 2.87+/-1.5 cm). Benign lesions were found in 15 patients (mean diameter+/-SD 2.04+/-2.7 cm). Mammography was definitely positive in 23/26 patients with breast cancer and indeterminate in 3/26 (sensitivity 88.4%). In benign lesions, mammography was true negative in 5/15 cases and indeterminate in 10/15 (specificity 33.3%). Both MIBI and (V)DMSA SMM detected 23/26 breast cancers (sensitivity 88.4%) and were true negative in 14/15 (specificity 93.3%). T/B ratios for breast cancer in MIBI and (V)DMSA scans were similar, and significantly higher than for benign lesions. MIBI correctly diagnosed 12/13 and (V)DMSA 11/13 cases in which the findings of mammography were indeterminate. In addition, (V)DMSA detected seven of eight cases of in situ ductal carcinoma (DCIS) associated with infiltrating carcinomas, while MIBI detected only two of these eight cases. (V)DSMA was also diffusely concentrated in benign lesions complicated by epithelial hyperplasia. Metastatic lymph node involvement was successfully imaged in 15/19 patients with metastatic disease by both agents (sensitivity 78.9%), while true-negative scans were observed in 19/22 (specificity 86.3%) patients with benign or malignant tumours without lymph node metastases. Linear regression analysis revealed a high coefficient of correlation between the (V)DMSA and the MIBI T/B ratios (r=0.8 P<0.001). We conclude that both (V)DMSA and MIBI show an excellent ability to detect breast cancer and its lymph node metastases. (V)DMSA also has a tendency to be diffusely and more intensely localised than MIBI in pre-invasive lesions, such as DCIS or epitheliosis, which are at risk of developing into malignancies. (V)DMSA could therefore provide a useful tool in the diagnosis of such lesions and possibly modify a predefined surgical plan. Finally, we believe that both tracers could offer an alternative method for elucidating nondiagnostic mammograms.

Abstract
The effects of two different protocols of 3-methylcholanthrene (3MC) and aspirin co-administration were studied in a well-established human hepatoma cell line (HepG2). During this work, we have performed toxicity tests for cell viability/cell proliferation as well as studies on the expression of ALDH3A1 after exposure of HepG2 cells to 3MC or/and aspirin. For the evaluation of toxic concentrations of 3MC and aspirin, the WST-1 test was used. WST-1 is a reliable cytotoxicity test which is based on the cleavage of the tetrazolium salt WST-1 to formazan by mitochondrial enzymes of living cells. A broad range of drug concentrations for either 3MC (0.25-50.0 microM) or aspirin (0.05-10.0 mM) were used for cell exposure, in several periods of time. The expression of ALDH3A1 in HepG2 cells showed typical time- and dose-response curves of induction after application of 3MC (1-5 days, 1.5-5.0 microM, respectively). When cells were firstly exposed to 3MC (2.5 and 5.0 microM) and then to aspirin (0.25 mM), the induced ALDH3A1 activity was further enhanced in a statistically significant way (P<0.05). On the contrary, when aspirin application was preceded 3MC exposuring a statistically significant decrease in ALDH3A1 inducibility was observed, as compared with the application of 3MC alone.

Abstract
The authors present a case of in situ ductal carcinoma of the breast (DCIS) with no associated mass in a 46-year-old woman examined with Tc-99m MIBI and Tc-99m(V) DMSA scans, which were acquired in separate sessions 10 minutes and 60 minutes after injection. Histologic analysis revealed a small (<1 cm) infiltrating ductal carcinoma located within the DCIS. Mammography showed a cluster of microcalcifications on a very dense parenchymal background. Tc-99m(V) DMSA was characterized as positive for DCIS, especially in the delayed image. Tc-99m MIBI failed to identify the lesions previously noted. In conclusion, Tc-99m(V) DMSA scintimammography seems to have an advantage and could improve the detection of nonpalpable in situ breast carcinomas.
