Abstract
BACKGROUND In first-line wild-type (WT)-Kirsten rat sarcoma viral oncogene homologue (KRAS) metastatic colorectal cancer (mCRC), panitumumab (Pmab) improves outcomes when added to FOLFOX [folinic acid, 5-fluorouracil, and oxaliplatin] or FOLFIRI [folinic acid, 5-fluorouracil, and irinotecan]. However no trial has directly compared these combinations. METHODS Multicentre, open-label study in untreated patients ≥ 18 years with (WT)-KRAS mCRC and multiple or unresectable liver-limited disease (LLD) randomised to either Pmab-FOLFOX4 or Pmab-FOLFIRI. The primary end-point was objective response rate (ORR). Secondary end-points included liver metastases resection rate (R0 + R1), progression-free survival (PFS), overall survival (OS), adverse events and perioperative safety. Exploratory end-points were: response by RAS status, early tumour shrinkage (ETS) and depth of response (DpR) in WT-RAS patients. RESULTS Data on 77 patients were analysed (38 Pmab-FOLFOX4; 39 Pmab-FOLFIRI; WT-RAS: 27/26, respectively). ORR was 74% with Pmab-FOLFOX4 and 67% with Pmab-FOLFIRI (WT-RAS: 78%/73%). Out of the above, 45% and 59% underwent surgical resection, respectively (WT-RAS: 37%/69%). The R0-R1 resection rate was 34%/46% (WT-RAS:26%/54%). Median PFS was 13/14 months (hazard ratio [HR] Pmab-FOLFIRI versus Pmab-FOLFOX4: 0.9; 95% confidence interval: [0.6-1.5]; WT-RAS:13/15; HR: 0.7 [0.4-1.3]). Median OS was 37/41 months (HR:1.0 [0.6-1.8]; WT-RAS: 39/49; HR:0.9 [0.4-1.9]). In WT-RAS patients with confirmed response, median DpR was 71%/66%, and 65%/77% of patients showed ETS ≥ 30%/ ≥ 20% at week 8, without significant differences between arms; these patients had longer median PFS and OS and higher resectability rates. Surgery was associated with longer survival. Perioperative and overall safety were similar, except for higher grade 3/4 neutropenia (40%/10%; p = 0.003) and neuropathy (13%/0%; p = 0.025) in the Pmab-FOLFOX4 arm. CONCLUSIONS In patients with WT-KRAS mCRC and LLD, both first-line Pmab-FOLFOX4 and Pmab-FOLFIRI resulted in high ORR and ETS, allowing potentially curative resection. No significant differences in efficacy were observed between the two regimens. (clinicaltrials.gov:NCT00885885).

Neoadjuvant and conversion treatment of patients with colorectal liver metastasis: the potential role of bevacizumab and other antiangiogenic agents. Target Oncol 2015; 10:453-65.

Abstract
More than 50 % of patients with colorectal cancer develop liver metastases. Surgical resection is the only available treatment that improves survival in patients with colorectal liver metastases (CRLM). New antiangiogenic targeted therapies, such as bevacizumab, aflibercept, and regorafenib, in combination with neoadjuvant and conversion chemotherapy may lead to improved response rates in this population of patients and increase the proportion of patients eligible for surgical resection. The present review discusses the available data for antiangiogenic targeted agents in this setting. One of these therapies, bevacizumab, which targets the vascular endothelial growth factor (VEGF) has demonstrated good results in this setting. In patients with initially unresectable CRLM, the combination of 5-fluorouracil, leucovorin, and oxaliplatin (FOLFOX) plus bevacizumab has led to high response and resection rates. This combination is also effective for patients with unresectable CRLM. Moreover, the addition of bevacizumab to chemotherapy in the neoadjuvant setting of liver metastasis has a higher impact on pathological response rate. This drug also has a manageable safety profile, and according to recent data, bevacizumab may protect against the sinusoidal dilation provoked in the liver by certain cytotoxic agents. In phase II trials, antiangiogenic therapy has demonstrated benefits in the presurgical treatment of CRLM and may represent a new treatment pathway for these patients.

Abstract
This phase II trial investigated the efficacy of an induction regimen of bevacizumab, capecitabine plus oxaliplatin (XELOX) followed by maintenance therapy with bevacizumab plus erlotinib as first-line therapy in patients with metastatic colorectal cancer. Patients with metastatic colorectal cancer received intravenous bevacizumab 7.5 mg/kg plus oxaliplatin 130 mg/m(2) on day 1 followed by oral capecitabine 1,000 mg/m(2) twice daily on days 1-14 every 3 weeks for six cycles. In the absence of disease progression, patients then received bevacizumab 7.5 mg/kg every 3 weeks plus oral erlotinib 150 mg once daily. The primary study endpoint was progression-free survival. In the intention-to-treat population (n = 90), the median progression-free survival was 9.2 [95% confidence interval (CI): 7.9-11.9] months, and the median overall survival was 25.8 (95% CI: 18.0-30.9) months. In the patient subpopulation who received both induction and maintenance therapy (n = 52), median progression-free survival was 11.1 (95% CI: 9.0-15.7) months, and the median overall survival was 29.5 (95% CI: 23.7-36.7) months. KRAS status did not predict efficacy. The most common grade 3/4 adverse events were diarrhea, asthenia, and neutropenia. XELOX-bevacizumab for 6 cycles followed by bevacizumab-erlotinib maintenance therapy has been shown to be a highly active and well-tolerated first-line regimen in patients with metastatic colorectal cancer.

Abstract
Ammonia-treated bagasse with 80%(w/w) moisture content was subjected to mixed-culture solid-substrate fermentation (SSF) with Trichoderma reesei LM-UC4 and Aspergillus phoenicis QM 329, in flask or pot fermenters, for cellulase production. Significantly higher activities of all the enzymes of the cellulase complex were achieved in 4 days of mixed-culture SSF than in single-culture (T. reesei) SSF. The highest filter-paper-cellulase and β-glucosidase activities seen in mixed-culture SSF were 18.7 and 38.6 IU/g dry wt, respectively, representing approx. 3- and 6-fold increases over the activities attained in single-culture SSF. The mixed-culture SSF process also converted about 46% of the cellulose and hemicellulose to reducing sugars and enriched the product with 13% fungal protein. The biomass productivity, 0.29 gl(-1).h, and enzyme productivity, 28.0 IU I(-1).h, were about twice as high in the mixed-culture than in the single-culture.

Effect of androgen blockade on HER-2 and matrix metalloproteinase-2 expression on bone marrow micrometastasis and stromal cells in men with prostate cancer. ScientificWorldJournal 2013; 2013:281291.

Abstract
INTRODUCTION HER-2 has been associated with castrate resistant prostate cancer and matrix metalloproteinase-2 (MMP-2) in the dissemination and invasion of tumor cells as well as activating angiogenesis. We present an immunocytochemical study of the effect of androgen blockade on the expression of HER-2 and MMP-2 in bone marrow micrometastasis and the surrounding stromal cells in men with prostate cancer. METHODS AND PATIENTS A cross-sectional study of men with prostate cancer. Touch preps were obtained from bone marrow biopsies of men with prostate cancer, before and after radical prostatectomy and during androgen blockade. Micrometastasis detected with anti-PSA immunocytochemistry underwent processing with anti-HER-2 and anti-MMP-2 immunocytochemistry. Patients were defined as HER-2 positive or negative, MMP-2 negative or an MMP-2 pattern described as border or central and stromal MMP-2 defined as positive or negative. The expression of the biomarkers was compared before and after primary treatment and during androgen blockade in relation to the serum PSA at the time of sampling and duration of androgen blockade. RESULTS 191 men participated, 35 men before surgery and 43 after surgery; there were no significant differences in HER-2 expression between groups, there was no MMP-2 expression centrally or stromal expression of MMP-2. In men with androgen blockade, HER-2 expression was significantly higher; there was a trend for increasing HER-2 expression up to 5 years; central MMP-2 expression significantly increased after 3 years, while stromal MMP-2 significantly increased after 6 years. MMP-2 expression both in micrometastasis and stroma was significantly associated with HER-2 expression. Expression of MMP-2 at the border of the micrometastasis was not associated with HER-2 expression and occurred in the absence of androgen blockade. CONCLUSIONS Androgen blockade decreases serum PSA by eliminating HER-2 negative prostate cancer cells. However, there is early selection of HER-2 positive cancer cells which leads to androgen independence and to increased expression of MMP-2 activity in the micrometastasis. The increased MMP-2 activity in the micrometastasis increases the expression of MMP-2 in the surrounding stromal cells and thus could promote angiogenesis and tumor growth resulting in macrometastatic androgen independent disease.

Abstract
OBJECTIVES Serum prostate specific antigen and digital rectal examination are the tests used as screening tests to detect prostate cancer. However, only approximately 30% of men with suspicion of cancer have it confirmed on prostate biopsy, and not all of these need treatment. Detection of circulating tumor cells in localized prostate cancer has given variable results, but it could be a useful complementary screening tool to detect prostate cancer in men with abnormal screening tests before the evaluation with prostate biopsy. This may be more so in subsequent biopsies where serum PSA has a decreased diagnostic yield. To evaluate the diagnostic yield of the detection of CPCs as a complementary PC screening test in a population fulfilling criteria for an initial, second and third prostate biopsy for suspicion of PC. METHODS A prospective screening study of consecutive patients aged 45-80 years presenting to the urologist for PC screening. Inclusion criteria were PSA >4.0 ng/ml, PSA velocity >0.35 ng/ml/year and/or DRE suspicious for cancer. Patients fulfilling inclusion criteria had blood taken for CPC detection and then underwent 12-core transrectal prostate biopsy. Double immune-his-tochemical staining with anti-PSA and anti-P504S was used to detect CPCs. Both cytologist and pathologist were blinded to the results of the biopsy, CPC results and clinical details. The diagnostic yield of the presence or absence of CPC was evaluated; the prostate biopsy was classified as cancer or no-cancer. RESULTS 282 men participated, 83 undergoing of these undergoing a second and 38 a third biopsy, with a mean age of 66.2 ± 8.9 years and a median serum PSA of 5.10 ng/ml, 5.45 ng/ml and 6.45 ng/ml for first, second and third biopsies. Cancer was detected in 33,6%, 10.8% and 29.0% of first, second and third biopsies respectively, CPCs were detected in 36.9%, 21.7% and 36.8% of the patients. Sensibility, specificity and negative predictive value were 86% ,91% and 94% for the first biopsy, 89%, 87% and 99% for the second and 100% , 89% and 100% for third biopsy respectively. All the CPC determinations were interpretable. There were 11 false negative cases, all with small low grade tumors. Of the 29 men with a false positive CPC, 8/10 had cancer detected in the subsequent biopsy. CONCLUSIONS The use of CPC detection could be useful as a complementary prostate cancer screening test, especially for excluding cancer, and including patients with indications for repeat biopsies. Men with a false positive CPC detection had a high risk of detecting cancer in the succeeding biopsy.

Abstract
INTRODUCTION Hand-foot syndrome (HFS) is a limiting toxicity of capecitabine, which is not life-threatening but could compromise capecitabine efficacy. MATERIALS AND METHODS This phase II, multicenter, non-controlled study assessed the safety, particularly grade three HFS incidence, and efficacy of four capecitabine-based chemotherapy regimens [cisplatin/capecitabine (CX), epirubicin/cisplatin/capecitabine (ECX), epirubicin/oxaliplatin/capecitabine (EOX) and docetaxel/cisplatin/capecitabine (DCX)] as first-line treatment for advanced and/or metastatic gastric cancer. RESULTS One hundred and eight patients were assigned to one of the four treatment groups, according to investigator's criteria, and grouped together for both safety and efficacy primary analyses. HFS was reported in 31 patients (19.6%) and its first presentation occurred at a median of 72 days (range 19-209 days). Grade 3 HFS developed in 6.3, 5.2, 3.7 and 2.4%, of patients receiving ECX, DCX, EOX or CX chemotherapy regimen, respectively. Capecitabine dose reduction/discontinuation due to HFS was required in 5.7% of patients (9/158). The most common (> 10%) grade 3-4 treatment-related AEs were neutropenia (15.2%), asthenia (12.0%) and diarrhoea (11.4%). CONCLUSIONS A moderate incidence of HFS was reported in patients treated with capecitabine, which generally presented late and required dose reduction in < 1/3 of patients. The results suggest that capecitabine may be useful in combination with standard fluorouracil-based regimens in patients with advanced and/or metastatic gastric cancer with favourable safety profile.

Abstract
PURPOSE The aim of this phase III trial was to compare the efficacy and safety of bevacizumab alone with those of bevacizumab and capecitabine plus oxaliplatin (XELOX) as maintenance treatment following induction chemotherapy with XELOX plus bevacizumab in the first-line treatment of patients with metastatic colorectal cancer (mCRC). PATIENTS AND METHODS Patients were randomly assigned to receive six cycles of bevacizumab, capecitabine, and oxaliplatin every 3 weeks followed by XELOX plus bevacizumab or bevacizumab alone until progression. The primary endpoint was the progression-free survival (PFS) interval; secondary endpoints were the overall survival (OS) time, objective response rate (RR), time to response, duration of response, and safety. RESULTS The intent-to-treat population comprised 480 patients (XELOX plus bevacizumab, n = 239; bevacizumab, n = 241); there were no significant differences in baseline characteristics. The median follow-up was 29.0 months (range, 0-53.2 months). There were no statistically significant differences in the median PFS or OS times or in the RR between the two arms. The most common grade 3 or 4 toxicities in the XELOX plus bevacizumab versus bevacizumab arms were diarrhea, hand-foot syndrome, and neuropathy. CONCLUSION Although the noninferiority of bevacizumab versus XELOX plus bevacizumab cannot be confirmed, we can reliably exclude a median PFS detriment >3 weeks. This study suggests that maintenance therapy with single-agent bevacizumab may be an appropriate option following induction XELOX plus bevacizumab in mCRC patients.

Sensibility, specificity and negative predictive value were 86.2%, 90.8% and 94.3% respectively. The negative and positive like-lihood ratios were 9.36 and 0.15. In men with a PSA <4.0ngml, 13.3% had cancer detected on biopsy, with a sensibility and specificity for mCPC detection of 83.3% and 84.6% and negative predictive value of 97.1%. All the mCPC determinations were interpretable. There were 9 false negative cases, all with small low grade tumors. CONCLUSIONS The use of mCPC detection could be useful as a complementary prostate cancer screening test, especially for excluding cancer, including patients with a serum PSA <4.0 ng/ml.

Abstract
IntroductionThe prevalence of psychiatric disorders in prison populations showed in other European countries has not been replicated in Spain.ObjectivesThe aim of the study was to estimate the lifetime and last month prevalence of mental disorders in a Spanish prison population sample. In this posetr we look a drug induced psychiatryc disorders found in this study.MethodThis is a descriptive cross-sectional epidemiological study. 783 male inmates were included in the study. Mental disorders were assessed with Structured Clinical Interview (SCID 1) for DSM-IV Axis 1 Disorders, clinical version and personality disorders were assessed by the Spanish version of the International Personality Disorders Examination.ResultsThe lifetime prevalence of mental disorder was 84.4%. Substance use disorder (abuse and dependence) was the most frequent disorder (76,2%): When look at substance induced diosder we found Mood induced disoder had lifetime prevalence of 15,8%(,13,2–18,5) and a last month prevalence of 2,8% (1,6–4,1), anxiety disoders were 16,1% (13,4–18,8) in lifetime prevalence and 5,9 (4,2–7,7) for last month prevalence and for subtance induce psychotic disoder lifetime prevalence was 7,1%(5,2–9,0) and last month prevalence was 2.0 (1.0–3.0). There is a 95 interval confidence on all these data.ConclusionsThe high prevalence of mental disorder and substance misuse is relevant both for the planning of health resource use in the prison environment and the prevention and approach to these disorders.

Abstract
In order to guarantee the required level of quality for our Bone &Tissue Banking, we evaluated a new CE marked container (CELLFLEX MacoPharma), for packing, transport, processing and storage of bones for therapeutic use. The use of CE marked containers is mandatory for organ and tissue containers (Medical Device Directive 93/42). We carried out a three-phase study: (1)Evaluation, (2) Implementation, (3)Audit The product was evaluated for the following criteria:Dash mechanical resistance, Dash air tightness, Dash fragility, Dash capacity. No damage was observed after the storage period, even after immersion in liquid nitrogen. No breakages were observed after provoked impact tests (pots dropped onto the floor). The pot capacity evaluation showed that the inner pot volume (approximately 500 ml) permits adequate storage of tendons and the majority of bone allografts. In conclusion, this evaluation has shown that the CELLFLEX kit is suitable for long duration preservation of bone allografts even at very low temperature conditions (vapour phase nitrogen). Its format and structure permit preservation of most bone allografts.

Abstract
INTRODUCTION Breast cancer is a disease with a very variable progression. Primary tumour size and metastatic lymph node involvement are the best indicators of the likelihood of relapse. However, their value in predicting progression following relapse is not clear. AIM The aim of this study was to asses whether the relationship between tumour size and the number of lymph nodes involved had any value as predictive factors of post-relapse progression. METHOD We established an index defined as the quotient between the number of diseased lymph nodes and the tumour size (in cm). RESULTS Applying this index in 230 consecutive patients with metastatic breast cancer, we observed that there was a significant inverse relation between the index and post-relapse progression. CONCLUSION We conclude that, at the time of initial diagnosis, the quotient of tumour size and the number of diseased lymph nodes could be a good predictor of time-to-progression following the diagnosis of the metastatic disease.

Detection of breast cancer cells in the peripheral blood is positively correlated with estrogen-receptor status and predicts for poor prognosis. Int J Cancer 2003; 107:984-90.

Abstract
We investigated whether detection of cytokeratin-positive (CK+) cells in the peripheral blood (PB) of breast cancer patients before chemotherapy could be a prognostic factor. Blood from a total of 92 breast cancer patients was evaluated for the presence of CK+ cells. Blood samples were collected before chemotherapy. Patients entered in the study included: neoadjuvant (n = 25), adjuvant (n = 42) and metastatic (n = 25). Blood samples (10 ml) were centrifuged using a double density-gradient to recovering the mononuclear cell (MNC) and granulocyte cell (GC) fractions. Subsequently, positive immunomagnetic cell separation was carried out to isolating CK+ cells. The enriched cell fraction was cytocentrifuged and then immunocytochemically labeled using an anti-cytokeratin antibody. Our results indicated that breast tumor cells sediment with both MNC and GC fractions. We therefore recommend examination of both fractions in all enrichment protocols. CK+ cells in PB were identified in 57 of 92 (62%) patients when MNC and GC fractions were assessed (range = 1-61 cells, median = 8). No CK+ cells were detected in blood samples of 16 healthy donors. There were significant differences in the presence of CK+ cells according to estrogen receptor expression (p = 0.049), and lymph node status (p = 0.033), but not to the age, menopausal status, type of patient (neoadjuvant, adjuvant or metastatic), TNM stage, histological type, progesterone receptor expression, c-erbB2 expression, p53 expression or Ki67 expression. Regarding the relationship between tumor size (T) and the presence of CK+ cells, a borderline significant trend was observed (p = 0.07). The median follow-up of the patients was 21 months and statistical analysis (Kaplan-Meier analysis) showed that using the method we present, the detection of CK+ cells in PB before starting the chemotherapy in breast cancer patients was significantly correlated with both progression-free survival (p = 0.058) and overall survival (p = 0.003). In conclusion, the present study suggests that detection of CK+ cells in PB before chemotherapy might identify breast cancer patients with poor prognosis.

Abstract
Neoadjuvant chemotherapy has become a standard treatment in the management of locally advanced breast cancer. Patients with earlier-stage disease may also benefit from neoadjuvant treatment in terms of improved rates of breast-conserving surgery and thus better quality of life. Gemcitabine is a pyrimidine analogue that has shown activity in a variety of solid tumors, a good toxicity profile, and nonoverlapping toxicity with other chemotherapeutic agents. Several phase II/III studies are assessing gemcitabine combined with anthracyclines, taxanes, and/or vinorelbine both in the neoadjuvant and metastatic disease settings. This article reviews developments in neoadjuvant use of gemcitabine in combination with anthracyclines and taxanes. Several phase II trials of gemcitabine combined with doxorubicin/epirubicin or with doxorubicin/paclitaxel have been carried out. Preliminary findings demonstrate increased complete response rates and good tolerability of these regimens in patients with breast cancer.

Abstract
In a single-center, open, phase II trial, we assessed the toxicity and activity of a triple combination therapy--doxorubicin at 30 mg/m2 (day 1), paclitaxel (Taxol) at 135 mg/m2 (day 2), and gemcitabine (Gemzar) at 2,500 mg/m2 (day 2 after paclitaxel)--administered biweekly in a 28-day cycle for six cycles. This was given as first-line treatment in 41 patients with metastatic breast cancer. Granulocyte colony-stimulating factor was used in 27 patients to permit maintenance of dose density. Hematologic toxicity was moderate. Nonhematologic adverse events were generally mild. The objective response rate was 82.9% (34/41) with 18 patients (43.9%) achieving complete response and 16 (38%) achieving partial response; progressive disease was observed in 4 patients (9.8%). Responses were observed at all metastatic sites, including complete responses in lung, liver, bone, and soft tissue. Median duration of response was 14.1 months and median time to progression was 13.9 months. Median survival was 26.2 months. The biweekly combination of gemcitabine, doxorubicin, and paclitaxel is safe and highly active as first-line treatment in metastatic breast cancer.
