Genome-wide association analyses of ovarian cancer patients undergoing primary debulking surgery identify candidate genes for residual disease.

Survival from ovarian cancer depends on the resection status after primary surgery. We performed genome-wide association analyses for resection status of 7705 ovarian cancer patients, including 4954 with high-grade serous carcinoma (HGSOC), to identify variants associated with residual disease. The most significant association with resection status was observed for rs72845444, upstream of MGMT, in HGSOC (p = 3.9 × 10-8). In gene-based analyses, PPP2R5C was the most strongly associated gene in HGSOC after stage adjustment. In an independent set of 378 ovarian tumours from the AGO-OVAR 11 study, variants near MGMT and PPP2R5C correlated with methylation and transcript levels, and PPP2R5C mRNA levels predicted progression-free survival in patients with residual disease. MGMT encodes a DNA repair enzyme, and PPP2R5C encodes the B56γ subunit of the PP2A tumour suppressor. Our results link heritable variation at these two loci with resection status in HGSOC.

Analysis of risk factors for recurrence in cervical cancer patients after fertility-sparing treatment: The FERTIlity Sparing Surgery retrospective multicenter study.

BACKGROUND: Fertility-sparing treatment in patients with cervical cancer should, in principle, follow identical algorithms to that in patients without future reproductive plans. In recent years, a trend toward nonradical procedures, such as conization or simple trachelectomy, has become apparent in medical literature, because of their associations with better pregnancy outcomes. However, the published reports included small numbers of patients and heterogenous treatment strategies to ascertain the safety of such approaches. OBJECTIVE: This study aimed to collect multi-institutional data regarding the oncological outcomes after fertility-sparing treatment in patients with cervical cancer and to identify prognostic risk factors, including the influence of the radicality of individual cervical procedures. STUDY DESIGN: Patients aged 18 to 40 years with International Federation of Gynecology and Obstetrics 2018 stage IA1 with positive lymphovascular space invasion or ≥IA2 cervical cancer who underwent any type of fertility-sparing procedure were eligible for this retrospective observational study, regardless of their histotype, tumor grade, and history of neoadjuvant chemotherapy. Associations between disease- and treatment-related characteristics with the risk of recurrence were analyzed. RESULTS: A total of 733 patients from 44 institutions across 13 countries were included in this study. Almost half of the patients had stage IB1 cervical cancer (49%), and two-thirds of patients were nulliparous (66%). After a median follow-up of 72 months, 51 patients (7%) experienced recurrence, of whom 19 (2.6%) died because of the disease. The most common sites of recurrence were the cervix (53%) and pelvic nodes (22%). The risk of recurrence was 3 times higher in patients with tumors >2 cm in size than in patients with smaller tumors, irrespective of the treatment radicality (19.4% vs 5.7%; hazard ratio, 2.982; 95% confidence interval, 1.383-6.431; P=.005). The recurrence risk in patients with tumors ≤2 cm in size did not differ between patients who underwent radical trachelectomy and patients who underwent nonradical (conization and simple trachelectomy) cervical procedures (P=.957), regardless of tumor size subcategory (<1 or 1-2 cm) or lymphovascular space invasion. CONCLUSION: Nonradical fertility-sparing cervical procedures were not associated with an increased risk of recurrence compared with radical procedures in patients with tumors ≤2 cm in size in this large, multicenter retrospective study. The risk of recurrence after any type of fertility-sparing procedure was significantly greater in patients with tumors >2 cm in size.

Optimal Treatment Duration of Bevacizumab as Front-Line Therapy for Advanced Ovarian Cancer: AGO-OVAR 17 BOOST/GINECO OV118/ENGOT Ov-15 Open-Label Randomized Phase III Trial.

PURPOSE: To compare standard versus extended duration of bevacizumab treatment in combination with front-line chemotherapy in women with newly diagnosed stage IIB-IV ovarian cancer. METHODS: In this multicenter, open-label, randomized phase III trial (ClinicalTrials.gov identifier: NCT01462890), patients with newly diagnosed International Federation of Gynecology and Obstetrics stage IIB-IV epithelial ovarian, fallopian tube, or peritoneal cancer underwent primary cytoreductive surgery followed by six cycles of chemotherapy (paclitaxel 175 mg/m2 plus carboplatin area under the curve 5 once every 3 weeks) and bevacizumab (15 mg/kg once every 3 weeks). Patients were randomly assigned 1:1 to receive bevacizumab for either 15 or 30 months, stratified by International Federation of Gynecology and Obstetrics stage/residual tumor. The primary end point was investigator-assessed progression-free survival (PFS) according to RECIST version 1.1. Secondary end points included overall survival (OS), safety, and tolerability. RESULTS: Between November 11, 2011, and August 6, 2013, 927 women were randomly assigned. There was no difference in PFS between treatment arms (hazard ratio, 0.99; 95% CI, 0.85 to 1.15; unstratified log-rank P = .90). Median PFS was 24.2 versus 26.0 months with standard versus extended duration of bevacizumab, respectively; restricted mean PFS was 39.5 versus 39.3 months, respectively. There was no OS difference between treatment arms (hazard ratio, 1.04; 95% CI, 0.87 to 1.23; P = .68). Serious/nonserious adverse events of special interest occurred in 29% versus 34% of patients in the standard versus experimental arms, respectively, and were consistent with the known safety profile of standard bevacizumab. CONCLUSION: Longer treatment duration with bevacizumab for up to 30 months did not improve PFS or OS in patients with primary epithelial ovarian, fallopian tube, or peritoneal cancer. A bevacizumab treatment duration of 15 months remains the standard of care.

Bevacizumab May Differentially Improve Prognosis of Advanced Ovarian Cancer Patients with Low Expression of VEGF-A165b, an Antiangiogenic VEGF-A Splice Variant.

PURPOSE: The identification of a robust IHC marker to predict the response to antiangiogenic bevacizumab in ovarian cancer is of high clinical interest. VEGF-A, the molecular target of bevacizumab, is expressed as multiple isoforms with pro- or antiangiogenic properties, of which VEGF-A165b is the most dominant antiangiogenic isoform. The balance of VEGF-A isoforms is closely related to the angiogenic capacity of a tumor and may define its vulnerability to antiangiogenic therapy. We investigated whether the expression of VEGF-A165b could be related to the effect of bevacizumab in advanced ovarian cancer patients. EXPERIMENTAL DESIGN: Formalin-fixed paraffin-embedded tissues from 413 patients of the ICON7 multicenter phase III trial, treated with standard platinum-based chemotherapy with or without bevacizumab, were probed for VEGF-A165b expression by IHC. RESULTS: In patients with low VEGF-A165b expression, the addition of bevacizumab to standard platinum-based chemotherapy significantly improved progression-free (HR: 0.727; 95% CI, 0.538-0.984; P = 0.039) and overall survival (HR: 0.662; 95% CI, 0.458-0.958; P = 0.029). Multivariate analysis showed that the addition of bevacizumab in low VEGF-A165b-expressing patients conferred significant improvements in progression-free survival (HR: 0.610; 95% CI, 0.446-0.834; P = 0.002) and overall survival (HR: 0.527; 95% CI, 0.359-0.775; P = 0.001), independently from established risk factors. CONCLUSIONS: We demonstrate for the first time that bevacizumab may differentially improve the prognosis of advanced ovarian cancer patients with low expression of VEGF-A165b, an antiangiogenic VEGF-A splice variant. We envision that this novel biomarker could be implemented into routine diagnostics and may have direct clinical implications for guiding bevacizumab-related treatment decisions in advanced ovarian cancer patients.

Developing a Clinico-Molecular Test for Individualized Treatment of Ovarian Cancer: The interplay of Precision Medicine Informatics with Clinical and Health Economics Dimensions.

We report recent progress in the development of a precision test for individualized use of the VEGF-A targeting drug bevacizumab for treating ovarian cancer. We discuss the discovery model stage (i.e., past feasibility modeling and before conversion to the production test). Main results: (a) Informatics modeling plays a critical role in supporting driving clinical and health economic requirements. (b) The novel computational models support the creation of a precision test with sufficient predictivity to reduce healthcare system costs up to $30 billion over 10 years, and make the use of bevacizumab affordable without loss of length or quality of life.

Phase II Study Evaluating PegLiposomal Doxorubicin and Carboplatin Combination Chemotherapy in Gynecologic Sarcomas and Mixed Epithelial-Mesenchymal Tumors A Phase II Protocol of the Arbeitsgemeinschaft Gynaekologische Onkologie Study Group (AGO-GYN 7).

BACKGROUND: Gynecologic sarcomas are rare diseases with still undefined optimal treatment. Platinum and anthracyclines were reported as active agents in gynecologic sarcoma and carcinosarcoma. So far, data regarding the combination of carboplatin and pegylated liposomal doxorubicin for this patient population are missing. METHODS: This prospective single-arm multicenter phase II trial evaluated the efficacy of carboplatin AUC 6 in combination with pegylated liposomal doxorubicin 40 mg/m q28 in 40 patients with newly diagnosed or recurrent gynecologic sarcoma or carcinosarcoma. RESULTS: Twenty patients with carcinosarcoma and 20 patients with leiomyosarcoma or endometrial stromal sarcoma were included. The percentage of patients with grade 3/4 neutropenia was 50%, but we did not observe any febrile neutropenia. The rates of grade 1 and 2 palmo-plantar erythema were moderate with 25% and 10%, respectively. Response rate was 33.3%. The 12-month progression-free and overall survival times were 32.5% and 77.0%, respectively. CONCLUSIONS: The combination of carboplatin and pegylated liposomal doxorubicin is feasible and has activity within the investigated study cohort.

Temsirolimus in women with platinum-refractory/resistant ovarian cancer or advanced/recurrent endometrial carcinoma. A phase II study of the AGO-study group (AGO-GYN8).

OBJECTIVES: To evaluate activity and toxicity of mTOR inhibitor temsirolimus in patients with platinum-refractory/resistant ovarian cancer (OC) or advanced/recurrent endometrial carcinoma (EC). METHODS: Women with epithelial ovarian, fallopian tube or primary peritoneal cancer were eligible, when they had progression during treatment with a platinum based regimen or within 6 months after receiving a platinum based regimen and a previous taxane treatment. Women with advanced/recurrent EC, no longer amenable to curative surgery and/or radiotherapy were eligible when they had no previous or only adjuvant chemotherapy. Preceding endocrine therapy for metastatic/recurrent disease was allowed. Patients received weekly IV infusions of 25mg temsirolimus. Primary endpoint was progression free survival rate after 4 months (OC) or 6 months (EC). A two stage design was applied. RESULTS: Forty-four patients (OC: n=22; EC: n=22) were enrolled and received temsirolimus treatment. Median age was 56 years (OC) or 63 years (EC). After eight weeks of treatment, 10 of 21 evaluable patients in the OC cohort and 8 of 20 evaluable patients in the EC cohort had progressive disease. Thus efficacy did not meet the predefined levels during the first stage of recruitment and the trial was stopped. Some patients in both cohorts had long lasting PFS (>7 months). Toxicity of temsirolimus was mild. CONCLUSIONS: Temsirolimus treatment was well tolerated in our patients, but did not meet the predefined efficacy criteria. In our study as in other trials on rapalogs in OC or EC, a few patients had long lasting disease stabilisations.

Borderline tumours of the ovary: A cohort study of the Arbeitsgmeinschaft Gynäkologische Onkologie (AGO) Study Group.

BACKGROUND: Borderline ovarian tumours (BOTs) are recognised as a unique entity of ovarian tumours that do not exert infiltrative destructive growth or stromal invasion. Prognosis of BOT is much better compared to the more common invasive epithelial ovarian cancer. Information regarding prognostic factors is inconclusive and no prospective studies exist that evaluate therapeutic strategies. We therefore started a retrospective-prospective cohort study to better understand BOT and identify scenarios in which future studies could be developed. METHODS: Consecutive patients with BOT treated between 1998 and 2008 in 24 German centres were analysed. The retrospective part of the study retrieved patients' data from hospital records and clinical tumour registries while active follow-up and an independent central pathology review were carried out prospectively. FINDINGS: BOT was confirmed in 950 patients, two thirds had serous BOT and 30.5% mucinous BOT. Most were diagnosed in stage I (82.3%); 7.6% and 10.1% had stages II and III, respectively. Overall, 74 patients (7.8%) experienced relapse and 43 (4.5%) died within the observation period. Multivariate analysis revealed higher stage, incomplete staging, tumour residuals, and organ preservation as independent prognostic factors for disease recurrence. Neither microinvasion nor micropapillary growth pattern showed any significant impact. Of 74 relapsed patients, 30% had malignant transformation to invasive ovarian cancer with five-year progression-free survival and overall survival of 12% and 50%, respectively. INTERPRETATION: Prognosis of BOT correlates with tumour-related as well as surgery-related factors. The balance between recurrence risk and organ preservation and fertility-sparing surgery is an important issue deserving further research.

Randomized phase II trial of carboplatin and paclitaxel with or without lonafarnib in first-line treatment of epithelial ovarian cancer stage IIB-IV.

OBJECTIVES: This study evaluates whether a molecular targeted therapy with the farnesyltransferase inhibitor lonafarnib added to standard chemotherapy in first-line treatment of advanced ovarian cancer (OC) could improve progression-free (PFS) and overall survival (OS). PATIENTS AND METHODS: We performed a prospective randomized phase II study to compare standard therapy carboplatin (C; AUC 5) and paclitaxel (T; 175 mg/m(2)) in primary advanced OC with or without lonafarnib (L). Lonafarnib was given in a dose of 100mg orally twice a day during chemotherapy and was increased afterwards to 200mg up to six months as a maintenance therapy. RESULTS: 105 patients were recruited (53 patients were randomized to receive LTC, 52 to TC). Hematologic toxicity was similar in both arms. Grade 3 and 4 non-hematological toxicity, occurred significantly more often with LTC (23% versus 4%, p=0.005) and was associated with a higher dropout rate. PFS and OS were not significantly different among both arms. The LTC arm showed inferiority in the stratum with residual tumor of more than 1cm: median PFS was 11.5 months (95% CI: 7.4-14.2) compared with 16.4 (95% CI: 10.3-40.4) for TC (p=0.0141; HR=0.36 (95% CI: 0.15-0.84)) with median OS 20.6 months (95% CI: 13.1-31.0) and 43.4 months (95% CI: 15.7-) for the TC arm (p=0.012; HR=0.32 (95% CI: 0.13-0.8)). CONCLUSION: The addition of lonafarnib did not improve PFS or OS. Patients with a residual tumor of more than 1cm had significantly shorter PFS and OS. Incorporation of lonafarnib into future studies for primary therapy of OC is not recommended.

Surgery in recurrent ovarian cancer: the Arbeitsgemeinschaft Gynaekologische Onkologie (AGO) DESKTOP OVAR trial.

BACKGROUND: The role of cytoreductive surgery in relapsed ovarian cancer is not clearly defined. Therefore, patient selection remains arbitrary and depends on the center's preference rather than on established selection criteria. The Descriptive Evaluation of preoperative Selection KriTeria for OPerability in recurrent OVARian cancer (DESKTOP OVAR) trial was undertaken to form a hypothesis for a panel of criteria for selecting patients who might benefit from surgery in relapsed ovarian cancer. METHODS: The DESKTOP trial was an exploratory study based on data from a retrospective analysis of hospital records. Twenty-five member institutions of the Arbeitsgemeinschaft Gynaekologische Onkologie Ovarian Committee (AGO OC) and AGO-OVAR boards collected data on their patients with cytoreductive surgery for relapsed invasive epithelial ovarian cancer performed in 2000-2003. RESULTS: Two hundred and sixty-seven patients were included. Complete resection was associated with significantly longer survival compared with surgery leaving any postoperative residuals [median 45.2 vs. 19.7 months; hazard ratio (HR) 3.71; 95% confidence interval (CI) 2.27-6.05; P < .0001]. Variables associated with complete resection were performance status (PS) [Eastern Cooperative Oncology Group (ECOG) 0 vs. > 0; P < .001], International Federation of Gynecology and Obstetrics (FIGO) stage at initial diagnosis (FIGO I/II vs. III/IV, P = .036), residual tumor after primary surgery (none vs. present, P <.001), and absence of ascites > 500 ml (P < .001). A combination of PS, early FIGO stage initially or no residual tumor after first surgery, and absence of ascites could predict complete resection in 79% of patients. CONCLUSIONS: Only complete resection was associated with prolonged survival in recurrent ovarian cancer. The identified criteria panel will be verified in a prospective trial (AGO-DESKTOP II) evaluating whether it will render a useful tool for selecting the right patients for cytoreductive surgery in recurrent ovarian cancer.

Randomized phase III trial of topotecan following carboplatin and paclitaxel in first-line treatment of advanced ovarian cancer: a gynecologic cancer intergroup trial of the AGO-OVAR and GINECO.

BACKGROUND: The combination of carboplatin and paclitaxel is the standard of care for the treatment of ovarian cancer, yet rates of recurrence and death remain high. We performed a prospective randomized phase III study to examine whether sequential administration of topotecan can improve the efficacy of carboplatin and paclitaxel in first-line treatment of advanced epithelial ovarian cancer. METHODS: A total of 1308 patients with previously untreated ovarian cancer (International Federation of Gynecology and Obstetrics stages IIB-IV) were randomly assigned to receive six cycles of paclitaxel and carboplatin followed by either four cycles of topotecan (TC-Top; 658 patients) or surveillance (TC; 650 patients) on a 3-week per cycle schedule. The primary endpoint was overall survival, and secondary endpoints were progression-free survival, response rate, toxicity, and quality of life. Time-to-event data were analyzed using the Kaplan-Meier method, and a stratified log-rank test was used to compare distributions between treatment groups. Hazard ratios (HRs) with 95% confidence intervals (CIs) were estimated using a Cox proportional hazards model. Categorical data were compared using a stratified Cochran-Mantel-Haenszel test. All statistical tests were two-sided. RESULTS: Median progression-free survival was 18.2 months in the TC-Top arm versus 18.5 months in the TC arm (stratum-adjusted HR = 0.97 [95% CI = 0.85 to 1.10]; P = .688). Median overall survival was 43.1 months for the TC-Top arm versus 44.5 months for the TC arm (stratum-adjusted HR = 1.01 [95% CI = 0.86 to 1.18]; P = .885). At 3 years, overall survival in both arms was 57% (58.5% in the TC arm and 55.7% in the TC-Top arm). Compared with patients in the TC arm, patients in the TC-Top arm had more grade 3-4 hematologic toxic effects (requiring more supportive care) and more grade 3-4 infections (5.1% versus 2.7%; P = .034) but did not have a statistically significant increase in febrile neutropenia (3.3% versus 3.1%; P = .80). Among patients who had measurable disease (TC, n = 147; TC-Top, n = 145), overall (i.e., complete or partial) response was 69.0% (95% CI = 61.4% to 76.5%) in the TC-Top arm and 76.2% (95% CI = 69.3% to 83.1%) in the TC arm (P = .166). CONCLUSIONS: The sequential addition of topotecan to carboplatin-paclitaxel did not result in superior overall response or progression-free or overall survival. Therefore, this regimen is not recommended as standard of care treatment for ovarian cancer.

GLUT1 mRNA and protein expression in ovarian borderline tumors and cancer.

OBJECTIVES: Increased glucose uptake and utilization is a major feature of malignant tumors. Recent studies suggest that the key mechanism of enhanced glucose metabolism in carcinoma cells involves the overexpression of transmembrane glucose transporter proteins (GLUTs). The aim of the present study was to analyze the expression of different GLUT isoforms (GLUT1-4) and to investigate whether alterations in their expression pattern accompany the malignant transformation and progression of ovarian cancer. METHODS: Tumor tissue of 94 patients suffering from primary ovarian cancer (n = 78) or borderline tumors (n = 16) and tissue from 16 patients with benign ovarian changes were examined in this study. Immunohistochemistry was performed using polyclonal GLUT1-4 antibodies. GLUT1 protein expression was quantified by Western blot analysis. GLUT1 mRNA expression was analyzed by mRNA in situ hybridization. RESULTS: All of the invasive carcinomas were positive for GLUT1. In contrast, GLUT1 expression was moderate in borderline tumors and weak to negative in all benign ovarian neoplasms. High GLUT1 mRNA levels were observed only in ovarian cancer. The intensity of GLUT1 expression in malignant ovarian neoplasms was associated neither with tumor characteristics nor with patient survival. Only GLUT3 revealed weak but homogeneous expression in human ovarian cancer as well as in benign ovarian tumors. GLUT2 and GLUT4 showed no expression in ovarian tissue. CONCLUSIONS: GLUT1 mRNA and protein were found to be expressed specifically in primary ovarian cancer. The close relationship between GLUT1 mRNA and protein expression points towards the potential relevance of GLUT1 as a diagnostic tool and therapeutic target in ovarian cancer.

GLUT1 messenger RNA and protein induction relates to the malignant transformation of cervical cancer.

We studied whether induction of glucose transporters (GLUTs) 1 to 4 correlates with human papillomavirus (HPV)-dependent malignant transformation of cervical epithelium. Tissue samples of cervical intraepithelial neoplasia (CIN; grades 1 to 3), invasive carcinomas, and lymph node metastasis were examined. HPV typing was performed. Tissue sections were immunostained with GLUT1 to GLUT4 antibodies. Messenger RNA (mRNA) in situ hybridization confirmed GLUT1 protein expression. Weak expression of GLUT1 was found in nondysplastic HPV-positive and HPV-negative epithelium; significant expression was observed in preneoplastic lesions, correlating with the degree of dysplasia. In CIN 3 high-risk HPV lesions, cervical cancer, and metastasis, GLUT1 was expressed at highest levels with a strong correlation of GLUT1 mRNA and protein expression. Immunostains for GLUT2 to GLUT4 were negative. Cervical tumor cells respond to enhanced glucose utilization by up-regulation of GLUT1. The strong induction of GLUT1 mRNA and protein in HPV-positive CIN 3 lesions suggests GLUT1 overexpression as an early event in cervical neoplasia. GLUT1 is potentially relevant as a diagnostic tool and glucose metabolism as a therapeutic target in cervical cancer.

A randomized clinical trial of cisplatin/paclitaxel versus carboplatin/paclitaxel as first-line treatment of ovarian cancer.

BACKGROUND: Despite considerable improvement in the treatment of advanced ovarian cancer, the optimization of efficacy and tolerability remains an important issue. Therefore, we performed a randomized, phase III non-inferiority trial comparing paclitaxel plus cisplatin (PT) with paclitaxel plus carboplatin (TC) in patients with advanced ovarian cancer. METHODS: A total of 798 patients with International Federation of Gynecology and Obstetrics stage IIB-IV were randomly assigned to receive six courses of either PT or TC at 3-week intervals. The primary endpoint was the proportion of patients without progression at 2 years. Secondary endpoints included toxicity, response to treatment, quality of life, and overall and progression-free survival time. Quality of life was evaluated using the European Organization for Research and Treatment of Cancer quality-of-life questionnaire (QLQ)-C30, version 2.0. Survival curves were calculated using the Kaplan-Meier method, and hazard ratios were estimated using the Cox proportional hazards model. RESULTS: The proportion of patients without progression at 2 years was not statistically significantly different between the two treatment arms (40.0% for PT versus 37.5% for TC, difference = 2.5%, one-sided 95% confidence interval [CI] = - infinity to 8.2%). Median progression-free survival time in the TC arm (17.2 months, 95% CI = 15.2 to 19.3 months) and the PT arm (19.1 months, 95% CI = 16.7 to 21.5 months) were also not statistically significantly different; the same was true of median overall survival time (43.3 months, 95% CI = 37.2 to 47.8 months versus 44.1 months, 95% CI = 40.2 to 49.4 months, for the TC and PT arms, respectively). The TC regimen was associated with a higher frequency of hematologic toxicity, but a lower frequency of gastrointestinal and neurologic toxicity, than the PT regimen. Mean global quality-of-life scores at the end of treatment were statistically significantly better in the TC arm than in the PT arm (65.25 versus 51.97, respectively; difference = -13.28, 95% CI = -18.88 to -7.68). CONCLUSION: The TC regimen achieved comparable efficacy to the PT regimen but was associated with better tolerability and quality of life, and should, therefore, be considered as an important alternative for standard first-line chemotherapy in patients with advanced ovarian cancer.

Long-term follow-up and prognostic significance of angiogenic basic fibroblast growth factor (bFGF) expression in patients with breast cancer.

The development of distant metastasis in breast cancer patients is the key step towards worse prognosis. The angiogenic basic fibroblast growth factor (bFGF) has been associated with tumorigenesis and metastasis in several human cancers. Therefore, bFGF expression was studied by immunohistochemistry in 111 patients with primary breast cancer. The results were correlated with prognostically relevant clinico-pathological features. such as tumor stage, grading. nodal stage and survival. bFGF was expressed in approximately 70% of the breast cancer tissues; 30% of the tumors showed strongly positive staining. With the exception of histological grading (p < 0.05), no correlation was found between the extent of bFGF expression and prognostic parameters. Analysis of survival showed a significantly (p < 0.05) prolonged survival for patients with a concomitant absence of axillary lymph node metastasis and bFGF immunoreactivity. Our data suggest that increased bFGF expression is a novel parameter for worse prognosis in nodal-negative breast cancer patients.
