    ABSTRACT: The establishment of high dependency units (HDUs) has been an undoubted advance in the management of patients undergoing major oncological procedures. The aim of this study was to examine the impact of various preoperative and perioperative patients' characteristics on the prolonged HDU stay. We conducted a retrospective study including all gynecologic oncology patients who underwent surgical management and were admitted postoperatively to our hospitals' HDU from 2006 to 2010. A total of 1,014 patients were transferred to the HDU and divided into two groups according to the length of HDU stay. Group A consisted of 840 (82.8 %) patients who stayed in the HDU for ≤24 h and Group B included 174 (17.2 %) patients who remained in the HDU under close observation for >24 h. Older age was the only preoperative characteristic that remained significantly associated with HDU prolonged stay. In addition, three intraoperative factors such as use of invasive hemodynamic monitoring, bowel resection and estimated blood loss were proved to be independently associated with prolonged HDU stay. Certain characteristics could identify those patients who are more likely to benefit most from HDU admission.

    ABSTRACT: The present review aims at providing an assessment of the clinical significance of Biphosphonates (BPs) in the treatment of patients with cancer. A systematic literature review was performed based on database search in PubMed/Medline and included articles up to August 2013. BPs can reduce, delay, and prevent complications related to bone metastases. They improve mobility, functionality, pain, and quality of life. They limit survival of any inactive cancer cells in the microenvironment of the bone marrow, contributing to their death from anti-neoplastic treatments. Moreover, they limit and delay bone morbidity due to osteoporosis related to hormonotherapy in breast and prostate cancer. Finally, benefits can be derived from the combination of BPs with radiotherapy in bone density, recalcification, opioid use, and patient's quality of life and performance status. The contribution of BPs in the course of certain neoplasms is preventive and synergistic to other treatments.

    ABSTRACT: To investigate the expression pattern of Y-box-binding protein 1 (YB1) in breast carcinomas, its clinicopathological and prognostic value, and its association with the breast cancer stem cell phenotype [CD44(+)/CD24(-/low)]. Immunohistochemistry was performed on 225 paraffin embedded specimens of invasive breast carcinomas to detect the expression of the proteins YB1, ER, PR, HER2, p53, Ki67, bcl-2, CD44 and CD24. YB1 protein was detected in the nuclei, the cytoplasm and the stroma of the tumor cells. Cytoplasmic YB1 was detected more often in carcinomas of ductal type (p = 0.002), of higher nuclear grade (p < 0.001), with lack of ER expression (p = 0.002), positive expression of p53 and Ki67 (p = 0.002 and p = 022, respectively), and with present CD44(+)/CD24(-/low) breast cancer stem cells (p = 0.001), while its association with bcl-2 was found to be inverse (p = 0.042). Nuclear YB1 was found to exert unfavorable impact on the disease-free survival of the unselected patients (p = 0.05) and the patients having been subjected to adjuvant chemotherapy and radiotherapy (p = 0.036 and p = 0.05, respectively). Cytoplasmic YB1 is associated with an aggressive and "stem cell-like" tumor phenotype, while nuclear localization discriminates patients at high risk for recurrence, especially those who are subjected to chemo- and radiotherapy.

    ABSTRACT: Peripheral T-cell lymphoma (PTCL) is a rare and heterogeneous group of non-Hodgkin lymphomas (NHLs). Whereas the incidence of the disease appears to increase during last decades and the prognosis remains dramatically poor, so far no standard treatment has been established. High-dose chemotherapy and autologous stem cell transplantation (HDT-ASCT) has been proven effective in relapsed PTCL, while retrospective studies have shown a survival benefit as first-line treatment in some subsets of PTCL patients. However, given disease rarity, there is a paucity of randomized trials in both upfront and relapse setting. Here, we critically evaluated eligible prospective and retrospective studies that address the role of ASCT in treatment of PTCL, with respect to quality of design and performance. Additionally, the role of allogeneic transplantation has been reviewed. The comparison of ASCT with novel agents that emerge or the combination of both, are to be ascertained via prospective randomized trials in this field.

    ABSTRACT: Pharmacological inhibition of Hsp90 shows great promise in breast cancer treatment. This is the first systematic review to synthesize all available data and to evaluate the efficacy and safety of Hsp90 inhibitors in breast cancer. This study was performed in accordance with the PRISMA guidelines. Eligible articles were identified by a search of MEDLINE and databases, using a predefined combination of the terms "breast", "cancer", "Hsp90", "inhibitors". Overall, 19 articles (190 patients) were eligible. The greatest clinical activity has been observed on the field of HER2-positive metastatic breast cancer. However, accumulating data suggest that Hsp90 inhibitors may play a significant role in the treatment of triple negative and aromatase inhibitor-resistant breast cancer. In the last decade, the development of Hsp90 inhibitors has moved forward rapidly; however, no phase III trials have been conducted and none agent has been approved for use in the clinical practice.

    ABSTRACT: Pancreatic cancer is the fourth leading cause of cancer-related death. Most patients present with an advanced stage of disease that has a dismal outcome, with a median survival of approximately 6 months. Evidently, there is a clear need for the development of new agents with novel mechanisms of action in this disease. A number of biological agents modulating different signal transduction pathways are currently in clinical development, inhibiting angiogenesis and targeting epidermal growth factor receptor, cell cycle, matrix metalloproteinases, cyclooxygenase-2, mammalian target of rapamycin, or proteasome. This is the first systematic review of the literature to synthesize all available data coming from trials and evaluate the efficacy and safety of molecular targeted drugs in unresectable and metastatic pancreatic cancer. However, it should be stressed that although multiple agents have been tested, only 9 phase 3 trials have been conducted and one agent (erlotinib) has been approved by the Food and Drug Administration for use in clinical practice. As knowledge accumulates on the molecular mechanisms underlying carcinogenesis in the pancreas, the anticipated development and assessment of molecularly targeted agents may offer a promising perspective for a disease which, to date, remains incurable.

    ABSTRACT: Significant controversy exists in the literature regarding the role of pregnancy in the prognosis of breast cancer. We designed a matched case-case study, matching pregnancy-associated breast cancer (PABC) cases with breast cancer cases for stage, age, and year of diagnosis. 39 consecutive cases of PABC were matched with 39 premenopausal cases of breast cancer. Univariate and multivariate survival analyses followed by adjustment for stage, grade, estrogen receptor status, and age at diagnosis, were performed. Regarding overall survival (OS), univariate analysis pointed to longer OS in non-PABC cases vs. PABC cases. Accordingly, a more advanced stage predicted shorter survival. In the multivariate analysis, the independent aggravating effect mediated by pregnancy persisted. Interestingly, a post hoc nested analysis within PABC cases indicated that the 3rd trimester pointed to shorter OS. The aforementioned results on OS were also replicated during the examination of relapse-free survival. Implementing a matched case-case design, the present study points to pregnancy as a poor prognostic factor for breast cancer.

    ABSTRACT: To evaluate breast cancer characteristics in women aged 25 years and younger. This was a retrospective, nested, within-cases matched study. The study design was based on a two-phase protocol. In the first phase, stage, grade, histologic subtype, estrogen receptor, progesterone receptor, and human epidermal growth factor receptor 2 status were compared between 28 patients (aged 25 years and younger) and 685 older premenopausal women (aged older than 25 years) with breast cancer. The second phase aimed to determine whether young patients exhibited worse prognosis when compared with older premenopausal women. Young patients presented at a more advanced stage (P=.012) and exhibited a higher grade (P=.018). No significant differences were noted regarding histologic subtype, estrogen receptor, and progesterone receptor status. Genetic testing for BRCA1 and BRCA2 mutations was performed in 12 of 28 young patients and mutations were found in 25% of them. Moreover, young women presented poorer overall survival (hazard ratio [HR] 4.30, 95% confidence interval [CI] 1.09-17.03) than their older counterparts, matched by histologic subtype, stage, and grade; a similar pattern was noted regarding relapse-free survival (HR 8.28, 95% CI 2.24-30.60). Breast cancer diagnosis in women aged 25 years and younger is uncommon; however, these patients present at a more advanced stage, with a higher grade, and exhibit poorer survival. : II.

    ABSTRACT: This case control study aims to investigate the role of MMP-2 -1306C > T polymorphism as a potential risk factor and possible prognostic marker for breast cancer in a South European population. 113 consecutive incident cases of histologically confirmed ductal breast cancer and 124 healthy controls were recruited. MMP-2 -1306C > T polymorphism was genotyped; multivariate logistic regression as well as Cox regression analysis were performed. MMP-2 -1306C > T status was not associated with breast cancer risk either at the total sample or at the subanalyses on premenopausal and postmenopausal women. At the survival analysis, a trend towards a favorable association between MMP-2 -1306C > T allele and disease-free survival as well as overall survival was observed. Regarding subanalyses on ER-negative and ER-positive cases, the favorable association implicating MMP-2 -1306C > T allele was particularly evident among ER-positive cases; no significant associations emerged among ER-negative cases. MMP-2 -1306C > T polymorphism does not seem to be a risk factor for breast cancer in South European population; however, a trend towards a favorable association with survival has been observed.

    ABSTRACT: BACKGROUND: The HER2 gene has been established as a valid biological marker for the treatment of breast cancer patients with trastuzumab and probably other agents, such as paclitaxel and anthracyclines. The TOP2A gene has been associated with response to anthracyclines. Limited information exists on the relationship of HER2/TOP2A gene status in the presence of centromere 17 (CEP17) gain with outcome of patients treated with anthracycline-containing adjuvant chemotherapy. METHODS: Formalin-fixed paraffin-embedded tumor tissue samples from 1031 patients with high-risk operable breast cancer, enrolled in two consecutive phase III trials, were assessed in a central laboratory by fluorescence in situ hybridization for HER2/TOP2A gene amplification and CEP17 gain (CEP17 probe). Amplification of HER2 and TOP2A were defined as a gene/CEP17 ratio of >=2.2 and >=2.0, respectively, or gene copy number higher than 6. Additionally, HER2, TopoIIa, ER/PgR and Ki67 protein expression was assessed by immunohistochemistry (IHC) and patients were classified according to their IHC phenotype. Treatment consisted of epirubicin-based adjuvant chemotherapy followed by hormonal therapy and radiation, as indicated. RESULTS: HER2 amplification was found in 23.7% of the patients and TOP2A amplification in 10.1%. In total, 41.8% of HER2-amplified tumors demonstrated TOP2A co-amplification. The median (range) of HER2, TOP2A and CEP17 gain was 2.55 (0.70-45.15), 2.20 (0.70-26.15) and 2.00 (0.70-26.55), respectively. Forty percent of the tumors had CEP17 gain (51% of those with HER2 amplification). Adjusting for treatment groups in the Cox model, HER2 amplification, TOP2A amplification, CEP17 gain and HER2/TOP2A co-amplification were not associated with time to relapse or time to death. CONCLUSION: HER2 amplification, TOP2A amplification, CEP17 gain and HER2/TOP2A co-amplification were not associated with outcome in high-risk breast cancer patients treated with anthracycline-based adjuvant chemotherapy.Trial registration: Australian New Zealand Clinical Trials Registry (ANZCTR) ACTRN12611000506998 and ACTRN12609001036202.

    ABSTRACT: Germline mutations in the BRCA1 and BRCA2 genes contribute to approximately 18% of hereditary ovarian cancers conferring an estimated lifetime risk from 15% to 50%. A variable incidence of mutations has been reported for these genes in ovarian cancer cases from different populations. In Greece, six mutations in BRCA1 account for 63% of all mutations detected in both BRCA1 and BRCA2 genes. This study aimed to determine the prevalence of BRCA1 mutations in a Greek cohort of 106 familial ovarian cancer patients that had strong family history or metachronous breast cancer and 592 sporadic ovarian cancer cases. All 698 patients were screened for the six recurrent Greek mutations (including founder mutations c.5266dupC, p.G1738R and the three large deletions of exon 20, exons 23–24 and exon 24). In familial cases, the BRCA1 gene was consequently screened for exons 5, 11, 12, 20, 21, 22, 23, 24. A deleterious BRCA1 mutation was found in 43/106 (40.6%) of familial cancer cases and in 27/592 (4.6%) of sporadic cases. The variant of unknown clinical significance p.V1833M was identified in 9/698 patients (1.3%). The majority of BRCA1 carriers (71.2%) presented a high-grade serous phenotype. Identifying a mutation in the BRCA1 gene among breast and/or ovarian cancer families is important, as it enables carriers to take preventive measures. All ovarian cancer patients with a serous phenotype should be considered for genetic testing. Further studies are warranted to determine the prevalence of mutations in the rest of the BRCA1 gene, in the BRCA2 gene, and other novel predisposing genes for breast and ovarian cancer.

    ABSTRACT: Background:The mesenchymal-epithelial transition (MET) pathway is frequently altered in tumours. The purpose of our study was to determine the prognostic value of tumour MET expression levels in patients with triple-negative breast cancer (TNBC), in order to strengthen the rationale for targeted therapy of TNBC using MET inhibitors.Methods:We determined expression of MET in formalin-fixed paraffin-embedded surgical specimens of TNBC by immunohistochemistry. Recurrence-free and overall survival was analysed with Cox models adjusted for clinical and pathological factors.Results:Immunostaining for MET was classified as high in 89 of 170 (52%) tumours. MET expression was more frequently observed in G3 carcinomas (P=0.02) but was not significantly associated to any of the other clinical or pathological parameters. High MET expression predicted shorter survival of the patients. Multivariate Cox proportional hazards regression analyses identified MET to be an independent prognostic factor for recurrence (adjusted hazard ratio (HR) for recurrence 3.43; 95% confidence interval (CI) 1.65-7.12; P=0.001) and death (adjusted HR for death 3.74; 95% CI 1.65-8.46; P=0.002).Conclusion:These results provide further evidence that the MET pathway could be exploited as a target for TNBC.British Journal of Cancer advance online publication, 19 February 2013; doi:10.1038/bjc.2013.31

    ABSTRACT: The main indication of prophylactic mastectomy pertains to BRCA1 or BRCA2 mutation carriers. Prophylactic mastectomy includes the simple method and the subcutaneous method. Both methods can be followed by breast plastic reconstruction either at the same time or later. This review examines key issues regarding prophylactic mastectomy: the selection of patients, its effectiveness, its limitations, convergence/divergence in existing guidelines, and future perspectives.

    ABSTRACT: AIMS: Our purpose was to investigate, in breast carcinomas, the prognostic importance of the proteins Wnt1 and glycogen synthasekinase (GSK)-3β, and their associations with classic clinicopathological indices. METHODS AND RESULTS: Immunohistochemistry was performed on paraffin-embedded tissue specimens from 288 invasive breast carcinomas to detect the expression of the proteins Wnt1, GSK3β, oestrogen receptor (ER), progesterone receptor (PR), erbB2, p53, Ki67, caspase-3 and β-catenin. Both Wnt1 and GSK3β were detected predominantly in the cytoplasm of the invasive tumour cells and the in-situ component, while GSK3β was also detected in the stromal fibroblasts. Wnt1 immunoreactivity in the invasive tumour cells showed an inverse association with histological grade (P = 0.002), Ki67 (P = 0.008) and p53 (P = 0.031), while its relation with ER, erbB2 and caspase-3 was found to be positive (P = 0.007, P = 0.018 and P = 0.03, respectively). Cytoplasmic Wnt1 expression was related to a favourable prognosis within the subgroup of patients with stage II disease (P = 0.032). CONCLUSIONS: Wnt1 expression in the invasive tumour cells seems to promote differentiation and apoptosis, while being related inversely to proliferation. Therefore, this suggests its participation in the primary stages of breast carcinogenesis. The latter is supported further by the immunodetection of Wnt1 in in-situ carcinomas.

    ABSTRACT: To explore the activity and safety of two schedules of ixabepilone, as first line chemotherapy, in patients with metastatic breast cancer previously treated with adjuvant chemotherapy, a randomized non-comparative phase II study was conducted. From November 2008 until December 2010, 64 patients were treated with either ixabepilone 40 mg/m(2) every 3 weeks (Group A, 32 patients) or ixabepilone 20 mg/m(2) on days 1, 8 and 15 every 4 weeks (Group B, 32 patients). Overall response rate (the primary end point) was 47% in Group A and 50% in Group B. The most frequent severe adverse events were neutropenia (32% vs. 23%), metabolic disturbances (29% vs. 27%) and sensory neuropathy (12% vs. 27%). Two patients in Group A and 3 in Group B developed febrile neutropenia. After a median follow-up of 22.7 months, median progression-free survival (PFS) was 9 months in Group A and 12 months in Group B. Median survival was 26 months in Group A, whereas it was not reached in Group B. Multiple genetic and molecular markers were examined in tumor and peripheral blood DNA, but none of them was associated with ORR or drug toxicity. Favorable prognostic markers included: the T-variants of ABCB1 SNPs c.2677G/A/T, c.1236C/T and c.3435C/T, as well as high MAPT mRNA and Tau protein expression, which were all associated with the ER/PgR-positive phenotype; absence of TopoIIa; and, an interaction between low TUBB3 mRNA expression and Group B. Upon multivariate analysis, tumor ER-positivity was a favorable (p = 0.0092) and TopoIIa an unfavorable (p = 0.002) prognostic factor for PFS; PgR-positivity was favorable (p = 0.028) for survival. In conclusion, ixabepilone had a manageable safety profile in both the 3-weekly and weekly schedules. A number of markers identified in the present trial appear to deserve further evaluation for their prognostic and/or predictive value in larger multi-arm studies. NCT 00790894.

    ABSTRACT: Despite the available prevention and early detection strategies, squamous-cell carcinoma of the uterine cervix is still diagnosed as locally advanced disease in a considerable proportion of patients. As a potent sensitizer of cancer cells, cisplatin has been the "traditional partner" of external beam irradiation in this setting for more than two decades. Induction chemotherapy strategies followed by concurrent chemoradiation or surgery and preoperative concurrent chemoradiation have been recently implemented in clinical trials in an effort to optimize local control and to minimize the risk of distant metastases. In this context, cisplatin has been combined with a number of other potential radiosensitizers, including 5-fluorouracil, capecitabine, and gemcitabine. In patients resistant or intolerant to platinum compounds, numerous non-platinum-containing regimens have been developed, implementing various antimetabolites, taxanes, antineoplastic antibiotics, and topoisomerase II inhibitors. More recently, molecular agents targeting critical pathways in cervical malignant transformation are being assessed in early clinical trials in combination with external-beam irradiation. In the current work, we review the evolving role of cisplatin and other platinum compounds, either alone or in combination regimens, in the context of other potent radiosensitizers. The emerging role of molecular targeted agents, as candidate partners of external beam irradiation, is also discussed.

    ABSTRACT: Landmark studies have established trastuzumab in the treatment of HER2-positive breast cancer. The present systematic review and meta-analysis aims to synthesize all available data, so as to evaluate the safety of trastuzumab during pregnancy. This study was performed in accordance with the PRISMA guidelines. All studies that examined the safety of trastuzumab administered during pregnancy, regardless of sample size, were considered eligible. Overall, 17 studies (18 pregnancies; 19 newborns) were included. In 55.6 % of cases, trastuzumab was administered in the metastatic setting. The mean duration of trastuzumab administration was 14.8 weeks. Occurrence of oligohydramnios/anhydramnios (O/A) was the most common (61.1 %) adverse event. 73.3 % of pregnancies exposed to trastuzumab during the second/third trimester were complicated with O/A; the respective rate of pregnancies exposed to trastuzumab exclusively during the first trimester was 0 % (P = 0.043). The mean GA at delivery was 33.8 weeks, and the mean weight of babies at delivery was 2,261 gr. In 52.6 % of cases, a healthy neonate was born. At the long-term evaluation, all children without problems at birth were healthy with a median follow-up of 9 months, while four out of nine children facing troubles at birth were dead within an interval ranging between birth and 5.25 months. All children exposed to trastuzumab in utero exclusively in the first trimester were completely healthy at birth. Trastuzumab should not be administered during pregnancy. However, for women who become accidentally pregnant during trastuzumab administration and wish to continue pregnancy, trastuzumab should be stopped and pregnancy could be allowed to continue.

    ABSTRACT: Landmark studies have established taxanes in the treatment of patients with breast cancer; however, recommendations regarding their administration during pregnancy are controversial. The present systematic review aims to synthesize all available data that stem exclusively from breast cancer case series to evaluate the efficacy and safety of taxanes during pregnancy. Overall, 16 studies (50 pregnancies) were eligible for the systematic review according to prisma guidelines. The mean age of patients with breast cancer at pregnancy was 34.6 years. The gestational age (GA) at chemotherapy administration varied from 12 to 36 weeks. The mean GA at delivery was 35.9 weeks. The mean weight of babies at delivery was 2380 g. In 76.7% of cases, a completely healthy neonate was born; in the remaining cases, a neonate who was dystrophic and premature, one with mild hydrocephalus, one with signs of bacterial sepsis, one with hyperbilirubinemia, one with apnea of prematurity, respiratory distress syndrome and gastroesophageal reflux, one with meconium-stained fluid, and another neonate with neutropenia and pyloric stenosis were reported. Ninety percent of children were completely healthy, with a median follow-up of 16 months; in the remaining cases, one child with recurrent otitis media, one with immunoglobulin A deficiency and mild constipation, and another child with delayed speech were reported. In conclusion, available data suggest that taxanes may potentially play a promising role in the optimal therapeutic strategy of patients with breast cancer diagnosed during pregnancy.

    ABSTRACT: This case control study aims to investigate the role of HSP90 Gln488His (C > G), HSP70-2 P1/P2, HIF-1 alpha C1772T and HSPA8 intronic 1541-1542delGT polymorphisms as potential risk factors and/or prognostic markers for breast cancer. 113 consecutive incident cases of histologically confirmed ductal breast cancer and 124 healthy cases were recruited. The above mentioned polymorphisms were genotyped; multivariate logistic regression was performed. HSP90 GG (His/His) genotype was associated with elevated breast cancer risk. Similarly, the allele dose-response model pointed to increase in breast cancer risk per G allele. HSP70-2 P1/P2, HSPA8 intronic 1541-1542delGT and HIF-1 alpha polymorphisms were not associated with breast cancer risk, as evidenced by the dose-response allele models. The positive association between HSP90 G allele and breast cancer risk seemed to pertain to both premenopausal and postmenopausal women. With respect to survival analysis, none of the aforementioned polymorphisms was associated with either disease-free survival or overall survival. HSP90α Gln488His polymorphism seems to be a risk factor for breast cancer. On the other hand, our study did not point to excess risk conferred by HSPA8 1541-1542delGT, Hsp70-2 P1/P2 and HIF-1α C1772T.
