Kallikrein-related peptidases 4, 5, 6 and 7 regulate tumour-associated factors in serous ovarian cancer. Br J Cancer 2018; 119:1-9. [PMID: 30287916 PMCID: PMC6189062 DOI: 10.1038/s41416-018-0260-1] [Citation(s) in RCA: 20] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/24/2018] [Revised: 08/08/2018] [Accepted: 08/16/2018] [Indexed: 11/09/2022] Open
Abstract
BACKGROUND Tissue kallikrein-related peptidases 4, 5, 6 and 7 (KLK4-7) strongly increase the malignancy of ovarian cancer cells. Deciphering their downstream effectors, we aimed at finding new potential prognostic biomarkers and treatment targets for ovarian cancer patients. KLK4-7-transfected (OV-KLK4-7) and vector-control OV-MZ-6 (OV-VC) ovarian cancer cells were established to select differentially regulated factors. METHODS With three independent approaches, PCR arrays, genome-wide microarray and proteome analyses, we identified 10 candidates (MSN, KRT19, COL5A2, COL1A2, BMP5, F10, KRT7, JUNB, BMP4, MMP1). To determine differential protein expression, we performed western blot analyses, immunofluorescence and immunohistochemistry for four candidates (MSN, KRT19, KRT7, JUNB) in cells, tumour xenograft and patient-derived tissues. RESULTS We demonstrated that KLK4-7 clearly regulates expression of MSN, KRT19, KRT7 and JUNB at the mRNA and protein levels in ovarian cancer cells and tissues. Protein expression of the top-upregulated effectors, MSN and KRT19, was investigated by immunohistochemistry in patients afflicted with serous ovarian cancer and related to KLK4-7 immunoexpression. Significant positive associations were found for KRT19/KLK4, KRT19/KLK5 and MSN/KLK7. CONCLUSION These findings imply that KLK4-7 exert key modulatory effects on other cancer-related genes and proteins in ovarian cancer. These downstream effectors of KLK4-7, MSN and KRT19 may represent important therapeutic targets in serous ovarian cancer.

Abstract
Phthalocyanine-BODIPY dye (BODIPY = boron dipyrromethene) was synthesized, fully characterized, and used for molecular recognition of CYFRA 21-1, a lung cancer biomarker, from whole blood samples. Thin films of three magnesium oxides ((MgO) n , where n = 8, 9, or 10)) were deposited on a paper substrate, and they were immersed in a solution of phthalocyanine-BODIPY dye (1.17 × 10-3 mol/L) for the design of stochastic sensors. Limits of determination of picograms per milliliter magnitude order were recorded for the proposed stochastic sensors. CYFRA 21-1 was reliably identified and determined with recoveries higher than 95% and RSD lower than 1% in whole blood samples.

Abstract
The availability of an ideal serum tumor marker would be of great clinical benefit for both the diagnosis and management of patients with epithelial ovarian cancer. Serum cancer antigen 125 assay significantly increases the diagnostic reliability of ultrasound in discriminating a malignant from a benign ovarian mass, especially in postmenopausal women, and it is the only well validated tumor marker for monitoring disease course. Several other tumor-associated antigens have been assessed, including glycoprotein antigens other than cancer antigen 125, soluble cytokeratin fragments, kallikreins, cytokines and cytokine receptors, vascular endothelial growth factor, D-dimer, and lisophosphatidic acid. This article assesses the potential diagnostic and prognostic role of these novel biomarkers, both alone and in combination with cancer antigen 125. The future for serum tumor marker research is represented by the emerging technology of proteomics, which may allow scientific advances comparable to those achieved with the introduction of monoclonal antibody technology.

Abstract
OBJECTIVES Cytokeratin 19 is significant for indicating cancer cells, and Cyfra 21-1 is a fragment of cytokeratin 19. This retrospective study was designed to define the prognostic value of serum Cyfra 21-1 in epithelial ovarian cancers (EOC). MATERIALS AND METHODS Serum Cyfra 21-1 concentration was obtained from 42 patients with EOC prior to treatment. Various prognostic aspects were examined using univariable and multivariable analyses. The standard serum marker cancer antigen 125 was measured simultaneously and compared in this analysis. RESULTS Serum levels of both Cyfra 21-1 and cancer antigen 125 were associated with positive retroperitoneal lymph nodes and platinum resistance; higher levels of Cyfra 21-1 (3.0 ng/mL as the cut-off) were associated with shorter disease-free survival (16 months vs. 28 months, p = 0.001) and overall survival (29 months vs. 41 months, p = 0.007) than lower levels. Further univariable analysis showed that Cyfra 21-1, poor differentiation, and retroperitoneal lymph node metastasis were related to platinum resistance and mortality. Multivariable analysis indicated retroperitoneal lymph node metastasis and serum Cyfra 21-1 were independent risk factors for both disease-free survival and overall survival. CONCLUSION The pretreatment level of serum Cyfra 21-1 had remarkable prognostic significance for EOC, indicating poor survival when it was elevated above 3.0 ng/mL.

Abstract
PURPOSE This study was conducted to determine the clinical significance of serum M30 and M65 in epithelial ovarian cancer (EOC). METHODS A total of 56 patients with EOC and 56 healthy women were included in the study. All of the patients received platinum-based chemotherapy. Pretreatment levels of M30 and M65 were measured using the quantitative ELISA method. RESULTS The median M30 and M65 serum levels were significantly elevated in the EOC patients compared with the healthy controls (96.7 vs. 69.5, p = 0.028 and 436.4 versus 166.3, p < 0.001, respectively). The cut-off value of 423.4 U/L for M65 determined with ROC analysis, predicted progression with 75.1 % sensitivity and 65.6 % specificity (AUC = 0.708, p = 0.008). Patients with higher M65 levels had shorter progression-free survival (PFS) (p = 0.021). Both M30 and M65 serum levels were significantly higher for serous-type histology (p = 0.001 and p < 0.001, respectively). Increased M65 serum levels were associated with advanced disease (p = 0.005) and higher grade (p = 0.005). Moreover, M65 levels were higher for chemotherapy-resistant patients (p = 0.04). Multivariate analysis revealed that an elevated serum M65 level was the only significant independent prognostic factor (p = 0.039, HR 3.792). CONCLUSIONS These results indicated that serum M30 and M65 levels were significantly elevated in patients with EOC compared with healthy women. Particularly, high serum M65 levels were associated with poor prognosis and resistance to platinum-based chemotherapy.

Abstract
OBJECTIVE To evaluate if serum and ascites VEGF-C concentration could be used as prognostic markers in ovarian cancer. MATERIALS AND METHODS Serum and ascites VEGF-C were measured in 118 patients with ovarian cancer and 24 patients with benign gynaecological disease. ELISA method was employed to evaluate VEGF-C concentration. RESULTS Serum and ascites in ovarian cancer patients were higher than those in benign gynaecological disease (P < 0.0001). Serum VEGF-C and ascites VEGF-C were both correlated with FIGO stage, tumor grade, and lymph node metastasis (P < 0.05). Univariate analysis revealed that FIGO stage (P < 0.0001), tumor grade (P < 0.0001), lymph node metastasis (P < 0.0001), serum VEGF-C concentration (P = 0.0001), and ascites VEGF-C concentration (P < 0.0001) were significantly correlated with overall survival. Including these variables in a multivariate analysis revealed that VEGF-C concentrations in serum and ascites were independent predictors of shorter overall survival. CONCLUSION Elevated VEGF-C concentrations in serum and ascites can be seen as the novel, widely available independent predictors of shorter overall survival in ovarian cancer.

Abstract
The validation of prognostic biomarkers in large independent patient cohorts is a major bottleneck in ovarian cancer research. We implemented an online tool to assess the prognostic value of the expression levels of all microarray-quantified genes in ovarian cancer patients. First, a database was set up using gene expression data and survival information of 1287 ovarian cancer patients downloaded from Gene Expression Omnibus and The Cancer Genome Atlas (Affymetrix HG-U133A, HG-U133A 2.0, and HG-U133 Plus 2.0 microarrays). After quality control and normalization, only probes present on all three Affymetrix platforms were retained (n=22,277). To analyze the prognostic value of the selected gene, we divided the patients into two groups according to various quantile expressions of the gene. These groups were then compared using progression-free survival (n=1090) or overall survival (n=1287). A Kaplan-Meier survival plot was generated and significance was computed. The tool can be accessed online at www.kmplot.com/ovar. We used this integrative data analysis tool to validate the prognostic power of 37 biomarkers identified in the literature. Of these, CA125 (MUC16; P=3.7×10(-5), hazard ratio (HR)=1.4), CDKN1B (P=5.4×10(-5), HR=1.4), KLK6 (P=0.002, HR=0.79), IFNG (P=0.004, HR=0.81), P16 (P=0.02, HR=0.66), and BIRC5 (P=0.00017, HR=0.75) were associated with survival. The combination of several probe sets can further increase prediction efficiency. In summary, we developed a global online biomarker validation platform that mines all available microarray data to assess the prognostic power of 22,277 genes in 1287 ovarian cancer patients. We specifically used this tool to evaluate the effect of 37 previously published biomarkers on ovarian cancer prognosis.

Abstract
Establishing CYFRA 21-1 detection for noninvasive differential diagnosis of urothelial carcinoma (UC) of bladder would help to improve assessment and follow-up of patients, as well as to improve screening of high-risk groups. The study group comprised of 147 subjects including 72 patients with UC of bladder, 75 controls and 17 follow-up cases. The levels of CYFRA 21-1 in serum, urine and urinary cell lysate were estimated by high sensitivity ELISA. Our results indicate that urinary CYFRA 21-1 provides a high value of overall sensitivity for UC of bladder and is also useful even for detection of low grade tumors that might indicate possible earlier detection and treatment administration.

Abstract
PURPOSE Early detection of ovarian cancer has great promise to improve clinical outcome. PATIENTS AND METHODS Ninety-six serum biomarkers were analyzed in sera from healthy women and from patients with ovarian cancer, benign pelvic tumors, and breast, colorectal, and lung cancers, using multiplex xMAP bead-based immunoassays. A Metropolis algorithm with Monte Carlo simulation (MMC) was used for analysis of the data. RESULTS A training set, including sera from 139 patients with early-stage ovarian cancer, 149 patients with late-stage ovarian cancer, and 1,102 healthy women, was analyzed with MMC algorithm and cross validation to identify an optimal biomarker panel discriminating early-stage cancer from healthy controls. The four-biomarker panel providing the highest diagnostic power of 86% sensitivity (SN) for early-stage and 93% SN for late-stage ovarian cancer at 98% specificity (SP) was comprised of CA-125, HE4, CEA, and VCAM-1. This model was applied to an independent blinded validation set consisting of sera from 44 patients with early-stage ovarian cancer, 124 patients with late-stage ovarian cancer, and 929 healthy women, providing unbiased estimates of 86% SN for stage I and II and 95% SN for stage III and IV disease at 98% SP. This panel was selective for ovarian cancer showing SN of 33% for benign pelvic disease, SN of 6% for breast cancer, SN of 0% for colorectal cancer, and SN of 36% for lung cancer. CONCLUSION A panel of CA-125, HE4, CEA, and VCAM-1, after additional validation, could serve as an initial stage in a screening strategy for epithelial ovarian cancer.

Abstract
OBJECTIVES The diagnosis of an adnexal mass is a prevalent issue among women in the United States, although current methods of identifying those at high risk of malignancy remain insufficient. Ineffective triage of women with malignant masses is associated with delayed or inappropriate treatment and a negative effect on disease outcome. METHODS We performed an evaluation of 65 ovarian cancer-related biomarkers in the circulation of women diagnosed with an adnexal mass. Our subject group consisted of women diagnosed with benign masses and early- and late-stage ovarian cancer. RESULTS More than half of the biomarkers tested were found to differ significantly between benign and malignant cases. As individual markers, HE4 and CA-125 provided the greatest level of discrimination between benign and malignant cases, and the combination of these two biomarkers provided a higher level of discriminatory power than either marker considered alone. Multivariate statistical analysis identified several multimarker panels that could discriminate early-stage, late-stage, and combined ovarian cancers from benign cases with similar or slightly improved SN/SP levels to the CA-125/HE4 combination; however, these larger panels could not outperform the 2-biomarker panel in an independent validation set. We also identified a 3-biomarker panel with particular utility in premenopausal women. CONCLUSIONS Our findings serve to advance the development of blood-based screening methods for the discrimination of benign and malignant ovarian masses by confirming and expanding upon the superior utility of the CA-125/HE4 combination.

Phase II trial of single agent cetuximab in patients with persistent or recurrent epithelial ovarian or primary peritoneal carcinoma with the potential for dose escalation to rash. Gynecol Oncol 2009; 113:21-7. [PMID: 19162309 DOI: 10.1016/j.ygyno.2008.12.003] [Citation(s) in RCA: 64] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/19/2008] [Revised: 12/01/2008] [Accepted: 12/04/2008] [Indexed: 12/14/2022]
Abstract
OBJECTIVES Determine if cetuximab dose escalation to induce grade 2 rash correlates with anti-tumor activity and if sera-based markers could predict likelihood of response. METHODS Patients with persistent/recurrent ovarian or primary peritoneal carcinoma received an initial dose of cetuximab 400 mg/m(2), then 250 mg/m(2) weekly for two 3-week cycles. Patients who had stable disease (SD) and <grade 2 rash were dose escalated in 75 mg/m(2) increments every 3 weeks until grade 2 rash or to a maximum weekly dose of 400 mg/m(2). Pre- and post-treatment serum samples were evaluated for potential predictive markers of response. RESULTS One of 25 patients achieved partial remission (PR) and 9 patients had SD. The median progression free survival was 2.1 months; the 1-year survival rate was 54.8%. Rash (96%) was the most common drug-related adverse event. At first response assessment, 4 patients remained at 250 mg/m(2); 8 patients were dose-escalated to 325 mg/m(2); of these, 4 ultimately were increased to 400 mg/m(2). Patients with progressive disease (PD) were removed from the study. Ninety-two serologic markers were analyzed from 20 patients to identify markers associated with clinical activity and/or predictive of outcome. Pretreatment levels of twelve markers were significantly elevated in patients exhibiting PD versus SD or PR; however, changes in marker levels during the course of treatment were not significant indicators of response. CONCLUSIONS Single-agent cetuximab showed minimal activity in patients with recurrent ovarian cancer. Patients with elevated levels of 12 serologic markers at baseline were more likely to have earlier disease progression.

Abstract
Tumour stage, residual disease after initial surgery, histological type and tumour grade are the most important clinical-pathological factors related to the clinical outcome of patients with epithelial ovarian cancer. In the last years, several investigations have assessed different biological variables in sera and in tissue samples from patients with this malignancy in order to detect biomarkers able to reflect either the response to chemotherapy or survival. The present paper reviewed the literature data about the predictive or prognostic relevance of serum CA 125, soluble cytokeratin fragments, serum human kallikreins, serum cytokines, serum vascular endothelial growth factor and plasma d-dimer as well as of tissue expression of cell cycle- and apoptosis-regulatory proteins, human telomerase reverse transcriptase, membrane tyrosine kinase receptors and matrix metalloproteinases. A next future microarray technology will hopefully offer interesting perspectives of translational research for the identification of novel predictive and prognostic biomarkers for epithelial ovarian cancer.

Abstract
Head and neck squamous cell carcinoma (HNSCC) is the sixth most common malignancy and is a major cause of cancer morbidity and mortality worldwide. Oral cancer is the most predominant malignancy in the Indian subcontinent due to the widespread habits of chewing tobacco and related products. Patients with oral tumours have a high risk of early locoregional relapse. Early detection of disease progression remains a challenging task mainly due to the lack of adequate early prognostic markers. CEA, SCC Ag, CA-125, serum cytokeratin (CK) fragments, Cyfra 21-1 (CK 19), TPS (CK 18), TPA (CK 8, 18, and 19) etc. are being used as serum markers for the prediction of prognosis of various malignancies. This review presents the available literature on serum CK markers in different malignancies evaluates their utility in the management of oral cancer, and identifies the lacunae which need to be addressed to develop sensitive and specific assays for early detection of recurrence, prognosis, and treatment monitoring.

Abstract
Pre-treatment serum squamous cell carcinoma antigen [SCC] levels are elevated in 28-88% of patients with squamous cell cervical cancer, and are related to tumour stage, tumour size, depth of stromal invasion, lymph-vascular space status, parametrial involvement and lymph node status. The clinical relevance of pre-treatment serum SCC assay is still debated. Some authors reported that it has no prognostic value, some others found that it is related to survival at univariate analysis, and some others detected that is an independent prognostic variable for survival. Serial SCC measurements reflect both the tumour response to treatment and the clinical outcome of patients. Increasing SCC levels can precede the clinical diagnosis of recurrent disease in 46-92% of the cases, with a mean lead time ranging from 2 to 8 months. According to some authors serum SCC assay during the follow-up does not improve the cure rate of patients who will ultimately develop a recurrence. However, it has been recently reported that the performance of a positron emission tomography [PET] in patients with asymptomatic SCC elevation can sometimes allow an earlier diagnosis of relapse with a survival benefit. SCC is a more sensitive serum tumour marker than CYFRA 21-1 for squamous cell cervical cancer in most series. Pre-treatment CA 125 levels are raised in 20-75% of patients with cervical adenocarcinoma, and reflect tumour stage, tumour size, histological grade, cervical stromal invasion, lymph-vascular space status and lymph node status. Elevated serum CA 125 has been also detected in patients with squamous cell cervical cancer, but with a positivity rate lower than that found in patients with cervical adenocarcinoma. Pre-treatment CA 125 levels appear to have a prognostic value, and rising serum CA 125 during follow-up may precede or be coincident with the clinical diagnosis of recurrent cervical adenocarcinoma. Serum levels of vascular endothelial growth factor [VEGF] are often elevated in patients with cervical cancer, and decrease significantly after successful treatment. However, the clinical relevance of serum VEGF assay is still investigational.

Abstract
BACKGROUND Sertoli-Leydig cell tumours of the ovary account for only 0.2% of malignant ovarian tumours. Two-thirds of all patients become apparent due to the tumour's hormone production. METHODS A 41-year-old patient (gravida 4, para 4) presented with dyspnoea, enlarged abdominal girth and melaena. Diagnostic imaging was suspicious for an ovarian cancer. The standard tumour marker for ovarian cancer (CA 125) was elevated to 984 U/mL. RESULTS Surgical exploration of the abdomen revealed a mouldering tumour of both adnexes extending to the level of the navel. Frozen sections showed an undifferentiated carcinoma of unknown origin. Radical surgery was performed. The final histological report described a malignant sex-cord stroma tumour, a Sertoli-Leydig cell tumour, emanating from both ovaries. Analysis of preoperative blood serum showed elevated levels of CYFRA 21-1 (10.4 ng/mL), neuron-specific enolase (36.2 ng/mL), oestradiol (485 pg/mL) and CA-125 (984 U/mL). Adjuvant chemotherapy and regional hyperthermia were performed due to the malignant potential and incomplete resection of the tumour. CONCLUSIONS Undifferentiated Sertoli-Leydig cell tumours show a poor clinical course. As only two-thirds of patients with this rare disease present with elevated hormone levels, new markers deserve further investigation to offer more specific, individualised tumour monitoring.

Abstract
The human epidermal growth factor receptor, type 2 (HER-2/neu or c-erbB-2) is a 185 kDa transmembrane protein that is phosphorylated upon ligand binding and dimerization with members of the HER/c-erbB family and regulates cell growth and differentiation. Its overexpression is strongly associated with advanced disease, metastasis and poor clinical outcome. To better understand the mechanisms underlying the poor prognosis of breast tumors with HER-2/neu-positive status, parallel proteomic analyses were performed on estrogen receptor-negative and node-positive breast tumors with or without overexpression of the HER-2/neu oncogene, using laser capture microdissection and two-dimensional gel electrophoresis. The differentially expressed proteins were identified by peptide mass fingerprinting using matrix-assisted laser desorption/ionization-time of flight mass spectrometry. Cytokeratin 19 (CK19), one of the identified proteins, was highly expressed in the HER-2/neu-positive breast tumors when compared with HER-2/neu-negative breast tumors. The enhanced overexpression of CK19 in HER-2/neu-positive tumors was further analyzed using semiquantitative reverse-transcription polymerase chain reaction, Western blotting and reverse-phase protein arrays. Immunohistochemical staining of sections from a breast tumor tissue microarray of 97 tumors showed moderate to strong staining against anti-CK19 antibody in 20 (5 with moderate and 15 with strong staining) of the 26 HER-2/neu-positive tumors (76.9%) and in 22 (12 with moderate and 10 with strong staining) of 52 HER-2/neu-negative tumors (48%) (p = 0.002). Our results indicate that CK19, an intermediate fragment of the cytoskeleton, and other proteins showing differential expression, are likely to be intricately involved in intra- and intercellular molecular events driving the more aggressive tumor proliferation, invasion and metastasis associated with HER-2/neu-positive tumors.

Abstract
CA 125 is the most reliable serum marker for ovarian carcinoma. Whereas its role in the screening of the malignancy is controversial, serum CA 125 assay is very useful for both the differential diagnosis of ovarian masses, particularly in postmenopause, and the monitoring of the response to chemotherapy and follow-up of patients with histologically proven ovarian carcinoma. Tumor-associated antigens other than CA 125, such as CA 19.9, CA 15.3 and TAG.72, firstly identified in gastro-intestinal or breast malignancies, have been detected also in tissue and serum samples from patients with ovarian carcinoma. In particular CA19.9 offers the advantage of high sensitivity for mucinous histotype, which often fails to express CA 125. Serum CA 125 correlates with the clinical course of disease better than the other antigens, and in patients with positive CA 125 assay at diagnosis the concomitant evaluation of CA 19.9 or CA 72.4 or CA 15.3 does not offer any additional benefit for monitoring ovarian carcinoma. Conversely, the serial measurements of these other antigens may represent an interesting biochemical tool for the management of patients with negative CA 125 assay. Serum alphaFP and betaHCG are very useful in the preoperative evaluation and management of nondysgerminomatous ovarian germ cell tumors, whereas elevated serum inhibin levels can be detected in patients with granulosa cell tumors of the ovary. As for endometrial carcinoma, preoperative serum CA 125 levels correlate with stage, depth of myometrial invasion, histologic grade, cervical invasion, peritoneal cytology, lymph node status and clinical outcome. Moreover, serial CA 125 assay is a good indicator of disease activity and a useful biochemical tool for post-treatment surveillance of patients with endometrial carcinoma. SCC is the most reliable serum marker for squamous cell cervical carcinoma, and in patients with this malignancy pretreatment SCC levels are related to tumor stage, tumor size, depth of cervical invasion, lymph-vascular space involvement, lymph node status and clinical outcome. Serial SCC measurements parallel the response to radiotherapy and chemotherapy as well as the clinical course of disease after the completion of treatment. Serum CYFRA 21.1 seems to be less sensitive than serum SCC for squamous cell cervical carcinoma. Elevated CA 125 levels can be often detected in patients with cervical adenocarcinoma. The future for tumor marker research is represented by the emerging technologies of transcriptional profiling and proteomics.

Abstract
BACKGROUND Patients with undifferentiated nasopharyngeal carcinoma (NPC) have elevated serum levels of CYFRA 21-1 (CYFRA), ferritin, and beta-2-microglobulin (beta2M) compared with healthy control individuals. The prognostic value of these markers has never been validated prospectively. METHODS Paired serum samples from 160 patients with newly diagnosed, nonmetastatic, undifferentiated NPC were collected before radiotherapy (RT) and at 4-6 weeks after the completion of RT. Pre-RT and post-RT levels of serum CYFRA, ferritin, and beta2M were analyzed and correlated with overall survival (OS), progression-free survival (PFS), time to locoregional recurrence, (TLR) and time to distant recurrence (TDR). The results of pre-RT and post-RT plasma Epstein-Barr virus (EBV) DNA levels available from a previous study were included in a Cox regression model together with age, tumor (T) classification, and lymph node (N) classification. RESULTS Sixty percent of patients had International Union Against Cancer Stage III-IV disease. At a median follow-up of 116 weeks (range, 37-239 weeks), 38 patients had disease progression. On multivariate analysis, pre-RT CYFRA and post-RT EBV DNA levels were independent predictors of poor OS, post-RT EBV DNA level and N classification predicted poor PFS and TDR; and only T classification predicted TLR. Patients who had pre-RT CYFRA levels > or = 1.5 U/mL were more likely to die (hazard ratio, 1.18; 95% confidence interval, 1.10-1.26) compared with patients who had pre-RT CYFRA levels < 1.5 U/mL. There were no associations between age, post-RT CYFRA levels and pre-RT or post-RT serum ferritin and beta2M levels, and the survival and recurrence rates on multivariate analysis. CONCLUSIONS Serum CYFRA levels taken before RT predicted reduced survival in patients with nonmetastatic, undifferentiated NPC who underwent RT.

Abstract
PURPOSE OF REVIEW The vast majority of women diagnosed with ovarian cancer and subsequently treated with debulking surgery and adjuvant chemotherapy will ultimately relapse. As is the case with primary diagnosis, detection of recurrent ovarian cancer is limited due to lack of sensitivity and specificity. Specific guidelines for surveillance of this disease are controversial, partly because evidence to support such guidelines is scant and partly because the management of identified recurrences continues to be of minimal success. Subsequently, whether early detection actually can make a difference is not necessarily made clear in the literature. However, there are advances in radiological and molecular biology technology that may offer new possibilities in cancer surveillance. This review will outline the latest evidence to address their use in ovarian cancer. RECENT FINDINGS Most of the recent literature involving detection of recurrent ovarian cancer addresses the use of positron emission tomography. There are also some data addressing the use of magnetic resonance imaging and computed tomography in this arena. Data pertaining to other modalities such as biological markers are limited. Ca-125 is the accepted assay used for ovarian cancer surveillance, but other options are introduced that may hold promise for the future. SUMMARY A review of the recent literature concerning ovarian cancer surveillance techniques offers few new definitive avenues. While radiological technology and discoveries in detection assays are noteworthy, their potential impact on surveillance appears to be minimal at this time. Low sensitivity and specificity, along with expense, continue to be limiting factors.

Abstract
Human kallikrein 11 (hK11/trypsin-like serine protease/TLSP, encoded by the KLK11 gene) is a member of the kallikrein family of secreted serine proteases. Recently, we developed a highly sensitive and specific immunoassay for hK11 and found that this protease is expressed in the prostate, stomach and trachea as well as in amniotic fluid and milk of lactating women. Elevated serum hK11 levels were found in 60% of men with prostate cancer and 70% of women with ovarian cancer. Also, hK11 expression was found to be under the regulation of steroid hormones, particularly estrogens, at the level of KLK11 transcription. We hypothesized that hK11 may be implicated in endocrine-related malignancies and serve as a novel prostate and ovarian cancer serological marker. The aim of our study was to examine if hK11 expression in ovarian tumors bears any prognostic significance. The concentration of hK11 (ng per mg of total protein) in 104 ovarian tumor cytosolic extracts was quantified and correlated with clinicopathologic variables and outcome over a median follow-up period of 67 months. Outcome was defined as progression-free survival (PFS) and overall survival (OS). hK11 concentration in ovarian tumor cytosols ranged from 0-21 ng/mg of total protein, with a median of 0.54 ng/mg. An optimal cutoff value of 0.54 ng/mg was selected to categorize tumors as hK11-positive or -negative. hK11-positive tumors were more frequently associated with early stage (Stage I/II) disease, pre-/peri-menopausal status and patients who exhibited complete or partial response to chemotherapy (p < 0.05). Univariate analysis revealed that patients with hK11-positive tumors had a significantly decreased risk of relapse with a hazard ratio (HR) of 0.45 (p = 0.007) and death (HR of 0.34, p = 0.005). Cox multivariate analysis indicated that hK11 was an independent prognostic indicator of OS (HR of 0.41, p = 0.025). Kaplan-Meier survival curves further confirmed that women with hK11-positive tumors have longer PFS and OS (p = 0.005 and p = 0.003, respectively). Similarly, in the subgroup of patients with grade 1-2 tumors, hK11-positivity was associated with higher OS in both univariate and multivariate analysis (HR of 0.23 and 0.17, p < 0.05). Finally, in women with optimal debulking after surgery (<1 cm residual tumor), hK11 positivity was associated with a slower disease progression. These results indicate that hK11 is a novel, independent marker of favorable prognosis in patients with ovarian cancer.
