Abstract
The association between beta human papillomavirus (HPV) types and cutaneous squamous cell carcinomas (cSCCs) is controversial. Several studies have found such an association, especially at early stages of carcinogenesis, but the presence of beta HPV types in aggressive cSCCs has only been reported in three patients previously. We aimed to search for beta HPV DNA in primary cSCCs and their corresponding lymph node metastases in a series of patients. The presence of DNA from 25 beta HPV types was determined using a multiplex PCR protocol in 35 primary cSCCs from 35 patients and their corresponding lymph node metastases. DNA from beta HPV types was detected in 9 % of primary cSCCs and in 13 % of metastases. No primary cutaneous SCC or lymphatic metastases were found to share the same HPV DNA. These data suggest that beta HPV types do not play an etiopathogenic role in advanced stages of squamous cell carcinogenesis.

Biological evidence for a causal role of HPV16 in a small fraction of laryngeal squamous cell carcinoma. Br J Cancer 2013; 109:172-83. [PMID: 23778529 PMCID: PMC3708587 DOI: 10.1038/bjc.2013.296] [Citation(s) in RCA: 86] [Impact Index Per Article: 7.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/11/2013] [Revised: 05/16/2013] [Accepted: 05/21/2013] [Indexed: 01/11/2023] Open
Abstract
BACKGROUND Human papillomavirus (HPV) is a causal factor in virtually all cervical and a subset of oropharyngeal squamous cell carcinoma (OP-SCC), whereas its role in laryngeal squamous cell carcinoma (L-SCC) is unclear. METHODS Formalin-fixed paraffin-embedded (N=154) and deep-frozen tissues (N=55) of 102 L-SCC patients were analysed for the presence of 51 mucosal HPV types. HPV DNA-positive (HPV DNA+) cases were analysed for E6*I mRNA transcripts of all high risk (HR)/probably/possibly (p)HR-HPV identified, and for HPV type 16 (HPV16) viral load. Expression of p16(INK4a), pRb, cyclin D1 and p53 was analysed by immunohistochemistry. RESULTS Ninety-two patients were valid in DNA analysis, of which 32 (35%) had at least one HPV DNA+ sample. Among the 29 single infections, 22 (76%) were HPV16, 2 (7%) HPV56 and 1 each (4%) HPV45, HPV53, HPV70, HPV11 and HPV42. Three cases harboured HPV16 with HPV33 (twice) or HPV45. Only 32% of HPV DNA+ findings were reproducible. Among HPV16 DNA+ L-SCC, 2 out of 23 (9%) had high viral loads, 5 out of 25 (21%) expressed E6*I mRNA and 3 out of 21 (14%) showed high p16(INK4a) and low pRb expression (all three HPV16 RNA-positive), immunohistochemical marker combination not identified in any other HPV DNA+ or HPV DNA-negative (HPV DNA-) L-SCC, respectively. CONCLUSION HPV type 16 has a causative role in a small subgroup of L-SCC (<5% in this German hospital series).

Abstract
Cervical carcinoma is the most common malignant tumor among woman in Paraguay. Cytological screening programs have not been successful and a plan for human papillomavirus (HPV) based-screening program and/or vaccination is under evaluation. This study aimed to identify the contribution of HPV genotypes in invasive cervical cancer in Paraguay to provide essential background data to guide and assess the introduction and impact of new preventive strategies based on HPV. Four hundred thirty two histologically confirmed cases (1960-2004) were analyzed. HPV detection in paraffin blocks was performed at the Catalan Institute of Oncology using PCR with SPF-10 broad spectrum primers followed by DNA enzyme immunoassay and genotyping with a reverse hybridization line probe analysis. The majority of cases were squamous cell carcinoma (92.8%). Mean patients age was 48 years old. HPV DNA was detected in 73.1% of the cases and single infections were predominant (97.8%). The most common HPV single types were 16, 18, 45, 33, 31, 52, 35, and 39. 73.1% of HPV positive cases had an HPV 16, 18 as single infection. HPV16 was frequent in SCC whereas HPV 18 and 45 were prevalent in glandular tumors. Significant decrease of HPV 16 with age groups (P-trend = 0.022) and increase in other HPV types (P-trend > 0.001) were observed. The potential impact of HPV 16 and 18 for a vaccination program was 73.1%. The study provide a profile of the HPV situation in the country, with robust clinical, pathological and virological data which would permit a better cervical cancer screening and vaccination programs.

Abstract
Background A protocol for cervical cancer screening among sexually active women 25 to 65 years of age was introduced in 2006 in Catalonia, Spain to increase coverage and to recommend a 3-year-interval between screening cytology. In addition, Human Papillomavirus (HPV) was offered as a triage test for women with a diagnosis of atypical squamous cells of undetermined significance (ASC-US). HPV testing was recommended within 3 months of ASC-US diagnosis. According to protocol, HPV negative women were referred to regular screening including a cytological exam every 3 years while HPV positive women were referred to colposcopy and closer follow-up. We evaluated the implementation of the protocol and the prediction of HPV testing as a triage tool for cervical intraepithelial lesions grade two or worse (CIN2+) in women with a cytological diagnosis of ASC-US. Methods During 2007-08 a total of 611 women from five reference laboratories in Catalonia with a novel diagnosis of ASC-US were referred for high risk HPV (hrHPV) triage using high risk Hybrid Capture version 2. Using routine record linkage data, women were followed for 3 years to evaluate hrHPV testing efficacy for predicting CIN2+ cases. Logistic regression analysis was used to estimate the odds ratio for CIN2 +. Results Among the 611 women diagnosed with ASC-US, 493 (80.7%) had at least one follow-up visit during the study period. hrHPV was detected in 48.3% of the women at study entry (mean age 35.2 years). hrHPV positivity decreased with increasing age from 72.6% among women younger than 25 years to 31.6% in women older than 54 years (p < 0.01). At the end of the 3 years follow-up period, 37 women with a diagnosis of CIN2+ (18 CIN2, 16 CIN3, 2 cancers, and 1 with high squamous intraepithelial lesions -HSIL) were identified and all but one had a hrHPV positive test at study entry. Sensitivity to detect CIN2+ of hrHPV was 97.2% (95%confidence interval (CI) = 85.5-99.9) and specificity was 68.3% (95%CI = 63.1-73.2). The odds ratio for CIN2+ was 45.3 (95% CI: 6.2-333.0), when among ASC-US hrHPV positive women were compared to ASC-US hrHPV negative women. Conclusions Triage of ASC-US with hrHPV testing showed a high sensitivity for the detection of CIN2+ and a high negative predictive value after 3 years of follow-up. The results of this study are in line with the current guidelines for triage of women with ASC-US in the target age range of 25-65. Non adherence to guidelines will lead to unnecessary medical interventions. Further investigation is needed to improve specificity of ASC-US triage.

Abstract
This study scans the efficacy of p16 immunostain on gynecological cytologies for the detection of high-grade lesions in ASCUS cases. This is a retrospective study that evaluates p16 immunostaining using frozen material from 109 cases diagnosed as ASCUS and followed for an average of 16 months. The diagnosis of ASCUS was made using liquid-based cytology (Thin Prep, Hologic, Marlborough, MA). High-risk HPV using Hybrid Capture II was performed. The immunohistochemical evaluation of p16 immunoreactivity was done following Wentzensen criteria. In the series p16 immunoreactivity showed a sensitivity and negative predictive value for HSIL, of 82.3 and 94.5% with specificity and positive predictive value of 100%. The sensitivity was similar to that found using the HC-II, though the specificity was much higher. The use of p16 immunostain in cytologic specimens applying the Wentzensen criteria helps to focus the attention in positive cells evaluating the cell changes, helps to detect some cells suspicious or diagnostic of HSIL, and could help to reclassify the ASCUS cases.

Abstract
OBJECTIVE To compare the results among conventional gynecologic cytology liquid-based cytology and manual screening and liquid-based cytology automatically screened. STUDY DESIGN The results of 53,311 cervicovaginal samples, corresponding to 53,311 women of Barcelona, Spain are reviewed. The cases are subdivided into 19,742 conventional cervicovaginal samples; 17,596 liquid-based cytology, manually screened samples; and 15,973 liquid-based automated-screened samples. RESULTS The automated screening increases the atypical squamous cells of undetermined significance and low-grade squamous intraepithelial lesion detection, in respect to liquid-based, manual screening and conventional cytology. In the follow-up, automated screening increases the diagnosis of squamous intraepithelial lesion (low-grade squamous intraepithelial lesion and high-grade squamous intraepithelial lesion). CONCLUSION Automated screening increases detection of all categories and increases the specificity for high-grade squamous intraepithelial lesion.

Abstract
BACKGROUND Axillary lymph node metastases in women are most frequently associated with breast cancer. Few cases have been reported to be related to other primary tumors of the breast. Furthermore, emperipolesis, a phenomenon that occurs as a result of the phagocytosis of hematopoietic cells by neoplastic cells, is observed in few tumors. CASE A 72-year-old woman presenting endometrial and breast cancer developed axillary metastasis 2 months after diagnosis of breast cancer. A fine needle aspiration was performed. A diagnosis of metastasis from endometrial cancer was made on the basis of cytological characteristics. CONCLUSION The morphologic features in this case (emperipolesis) oriented as axillary metastases from primary endometrial cancer.

Abstract
BACKGROUND Knowledge about the distribution of human papillomavirus (HPV) genotypes in invasive cervical cancer is crucial to guide the introduction of prophylactic vaccines. We aimed to provide novel and comprehensive data about the worldwide genotype distribution in patients with invasive cervical cancer. METHODS Paraffin-embedded samples of histologically confirmed cases of invasive cervical cancer were collected from 38 countries in Europe, North America, central South America, Africa, Asia, and Oceania. Inclusion criteria were a pathological confirmation of a primary invasive cervical cancer of epithelial origin in the tissue sample selected for analysis of HPV DNA, and information about the year of diagnosis. HPV detection was done by use of PCR with SPF-10 broad-spectrum primers followed by DNA enzyme immunoassay and genotyping with a reverse hybridisation line probe assay. Sequence analysis was done to characterise HPV-positive samples with unknown HPV types. Data analyses included algorithms of multiple infections to estimate type-specific relative contributions. FINDINGS 22,661 paraffin-embedded samples were obtained from 14,249 women. 10,575 cases of invasive cervical cancer were included in the study, and 8977 (85%) of these were positive for HPV DNA. The most common HPV types were 16, 18, 31, 33, 35, 45, 52, and 58 with a combined worldwide relative contribution of 8196 of 8977 (91%, 95% CI 90-92). HPV types 16 and 18 were detected in 6357 of 8977 of cases (71%, 70-72) of invasive cervical cancer. HPV types 16, 18, and 45 were detected in 443 of 470 cases (94%, 92-96) of cervical adenocarcinomas. Unknown HPV types that were identified with sequence analysis were 26, 30, 61, 67, 69, 82, and 91 in 103 (1%) of 8977 cases of invasive cervical cancer. Women with invasive cervical cancers related to HPV types 16, 18, or 45 presented at a younger mean age than did those with other HPV types (50·0 years [49·6-50·4], 48·2 years [47·3-49·2], 46·8 years [46·6-48·1], and 55·5 years [54·9-56·1], respectively). INTERPRETATION To our knowledge, this study is the largest assessment of HPV genotypes to date. HPV types 16, 18, 31, 33, 35, 45, 52, and 58 should be given priority when the cross-protective effects of current vaccines are assessed, and for formulation of recommendations for the use of second-generation polyvalent HPV vaccines. Our results also suggest that type-specific high-risk HPV-DNA-based screening tests and protocols should focus on HPV types 16, 18, and 45.

Abstract
Background Human Papillomavirus (HPV) detection results comparing paraffin embedded cervical tissue and other cervical specimens have been done with varying degrees of agreement. However, studies comparing freshly frozen specimens and paraffin embedded specimens of invasive cervical carcinomas are lacking. The aim of the study was to compare HPV detection using SPF10 broad-spectrum primers PCR followed by DEIA and genotyping by LiPA25 (version 1) between freshly frozen cervical tissue samples and paraffin embedded blocks of cervical tissue from the same patient. There were 171 pairs of paraffin embedded and freshly frozen samples analyzed from cervical carcinoma cases from Kampala, Uganda. Results 88.9% (95% CI: 83.2%-93.2%) of paraffin embedded samples were HPV positive compared with 90.1% (95% CI: 84.6%-94.1%) of freshly frozen samples, giving an overall agreement in HPV detection between fresh tissue and paraffin embedded tissue at 86.0% (95% CI: 79.8%-90.8%). Although the proportion of HPV positive cases in freshly frozen tissue was higher than those in paraffin blocks, the difference was not statistically significant (p > 0.05). In both types of tissues, single HPV infections were predominant, with HPV16 accounting for 47% of positive cases. Comparison in the overall agreement, taking into accounts not only positivity in general, but also HPV types, showed a 65% agreement (complete agreement of 59.7%, partial agreement of 5.3%) and complete disagreement of 35.0%. HPV detection in squamous cell carcinomas (SCC) and adenocarcinomas (ADC) was similar in fresh tissue or paraffin blocks (p ≥ 0.05). p16 immunostaining in samples that had at least one HPV negative results showed that 24 out of 25 cases had an over-expressed pattern. Conclusions HPV DNA detection was lower among ADC as compared to SCC. However, such differences were minimized when additional p16 testing was added, suggesting that the technical issues may largely explain the HPV negative cases.

Abstract
There is limited information on the prevalence of sexually transmitted infections and the prevalence of cervical neoplasia in rural sub-Saharan Africa. This study describes the prevalence and the etiology of STIs and the prevalence of cervical neoplasia among women in southern Mozambique. An age-stratified cross-sectional study was performed where 262 women aged 14 to 61 years were recruited at the antenatal clinic (59%), the family-planning clinic (7%), and from the community (34%). At least one active STI was diagnosed in 79% of women. Trichomonas vaginalis was present in 31% of all study participants. The prevalence of Neisseria gonorrhea and Chlamydia trachomatis were 14% and 8%, respectively, and Syphilis was diagnosed in 12% of women. HPV DNA was detected in 40% of women and cervical neoplasia was diagnosed in 12% of all women. Risk factors associated with the presence of some of the STIs were being divorced or widowed, having more than one sexual partner and having the partner living in another area. A higher prevalence was observed in the reproductive age group and some of the STIs were more frequently diagnosed in pregnant women. STI control programs are a priority to reduce the STIs burden, including HIV and cervical neoplasia.

Abstract
Background The origin of adenocarcinomas presenting on the cervix uteri may be doubtful, i.e. whether it is of cervical or endometrial origin, due to the overlapping morphological features. In HPV negative samples, further tests may be needed to ascertain the nature of the tumours. We aimed to explore the use of immunohistochemistry profiles in tissue microarrays in archived samples of adenocarcinoma (ADC) of the cervix from Uganda that tested negative for HPV DNA. Findings Five commercially available antibodies were tested in tissue array sections immunostained utilizing the avidin-biotin (AB) technique. In 26 ADC samples, HPV was detected in 13, p16 in 15 (8 in HPV positive and 7 in HPV negative), CEA in 12, vimentin in 6, ER in 0, and PR in 2. Among the 13/25 HPV negative ADC samples, five were positive for CEA suggesting endocervical origin, and three were vimentin positive (one had a mucinous endocervical histological pattern and two were ADC, not otherwise specified, most likely of endometrial origin). Conclusions The immunoprofiles of ADC with the antibodies studied are rather nonspecific. By using immunohistochemistry in 13 HPV negative ADC, endocervical tumour origin was suspected in five CEA positive cases while two out of three vimentin positive samples were probably of endometrial origin, suggesting that CEA and vimentin may be valuable in distinguishing HPV negative cervical adenocarcinomas from endometrial adenocarcinomas.

Abstract
OBJECTIVE To describe the HPV genotype distribution and to investigate the underlying secular trend in the relative contribution of HPV types 16-18 in invasive cervical cancer (ICC) over a period of 47 years (1958-2004) in South Korea. METHODS Paraffin embedded ICC samples were obtained from historical archives of two hospitals in Korea. HPV detection and genotyping was performed by SPF10 PCR, DEIA and LiPA25 assays (version 1). RESULTS Of 874 ICC cases, 742 were considered suitable for HPV DNA testing after histological evaluation. Squamous cell carcinoma was the major histological type (93.0%). HPV was detected in 674 of the 742 specimens (90.8%). The five most common types identified as single types among HPV-positive cases were HPV16 (63.1%), HPV18 (8.5%), HPV33 (4.5%), HPV58 (3.9%) and HPV31 (3.0%). Multiple infections were detected in 5%. HPV16-18 together accounted for 72% of all HPV-positive cervical cancers with no statistically significant differences by time at diagnosis (adjusted model-p>0.05). CONCLUSION This present study confirmed the role of HPV infection as the main factor in cervical cancer in Korea. HPV16-18 accounted for more than 70% in cervical cancer and there was no statistically significant secular trend for the past 50 years.

Abstract
The natural history of cancers associated with virus exposure is intriguing, since only a minority of human tissues infected with these viruses inevitably progress to cancer. However, the molecular reasons why the infection is controlled or instead progresses to subsequent stages of tumorigenesis are largely unknown. In this article, we provide the first complete DNA methylomes of double-stranded DNA viruses associated with human cancer that might provide important clues to help us understand the described process. Using bisulfite genomic sequencing of multiple clones, we have obtained the DNA methylation status of every CpG dinucleotide in the genome of the Human Papilloma Viruses 16 and 18 and Human Hepatitis B Virus, and in all the transcription start sites of the Epstein-Barr Virus. These viruses are associated with infectious diseases (such as hepatitis B and infectious mononucleosis) and the development of human tumors (cervical, hepatic, and nasopharyngeal cancers, and lymphoma), and are responsible for 1 million deaths worldwide every year. The DNA methylomes presented provide evidence of the dynamic nature of the epigenome in contrast to the genome. We observed that the DNA methylome of these viruses evolves from an unmethylated to a highly methylated genome in association with the progression of the disease, from asymptomatic healthy carriers, through chronically infected tissues and pre-malignant lesions, to the full-blown invasive tumor. The observed DNA methylation changes have a major functional impact on the biological behavior of the viruses.

Abstract
OBJECTIVE To obtain large scale and generalisable data on the long term predictive value of cytology and human papillomavirus (HPV) testing for development of cervical intraepithelial neoplasia grade 3 or cancer (CIN3+). DESIGN Multinational cohort study with joint database analysis. SETTING Seven primary HPV screening studies in six European countries. PARTICIPANTS 24,295 women attending cervical screening enrolled into HPV screening trials who had at least one cervical cytology or histopathology examination during follow-up. MAIN OUTCOME MEASURE Long term cumulative incidence of CIN3+. RESULTS The cumulative incidence rate of CIN3+ after six years was considerably lower among women negative for HPV at baseline (0.27%, 95% confidence interval 0.12% to 0.45%) than among women with negative results on cytology (0.97%, 0.53% to 1.34%)). By comparison, the cumulative incidence rate for women with negative cytology results at the most commonly recommended screening interval in Europe (three years) was 0.51% (0.23% to 0.77%). The cumulative incidence rate among women with negative cytology results who were positive for HPV increased continuously over time, reaching 10% at six years, whereas the rate among women with positive cytology results who were negative for HPV remained below 3%. CONCLUSIONS A consistently low six year cumulative incidence rate of CIN3+ among women negative for HPV suggests that cervical screening strategies in which women are screened for HPV every six years are safe and effective.

Abstract
PURPOSE To evaluate the efficacy of treatment with the aromatase inhibitor letrozole in breast cancer patients segregated with respect to DNA polymorphisms of the aromatase gene CYP19. PATIENTS AND METHODS Postmenopausal patients (n = 67) with hormone receptor-positive metastatic breast cancer were treated with the aromatase inhibitor letrozole. PCR allelic discrimination was used to examine three single-nucleotide polymorphisms (SNP) in DNA obtained from breast carcinoma tissue. Two SNPs analyzed (rs10046 and rs4646) were located in the 3' untranslated region and one (rs727479) was in the intron of the aromatase CYP19 gene. The primary end point of treatment efficacy was time to progression (TTP). RESULTS Median age was 62 years and median number of metastatic sites was 2. Observed allelic SNP frequencies were rs10046, 71%; rs4646, 46%; and rs727479, 63%. Of the 67 patients, 65 were evaluable for efficacy. Median TTP was 12.1 months. We observed no relationship between TTP and the rs10046 or rs727479 variants. In contrast, we found that TTP was significantly improved in patients with the rs4646 variant, compared with the wild-type gene (17.2 versus 6.4 months; P = 0.02). CONCLUSION In patients with hormone receptor-positive metastatic breast cancer treated with the aromatase inhibitor letrozole, the presence of a SNP in the 3' untranslated region of the CYP19 aromatase gene is associated with improved treatment efficacy. Testing for the CYP19 rs4646 SNP as a predictive tool for breast cancer patients on antiaromatase therapy deserves prospective evaluation.

Abstract
OBJECTIVE To evaluate the presence of human papillomavirus (HPV) infection, the methylation status in the promoter region of thrombospondin-1 (TSP-1), RAS association domain family 1A (RASSF1-A) and p16 genes, and the expression of TSP-1, CD31, p16 and p53 proteins in patients diagnosed with penile cancer, and the possible associations between these variables and clinical and pathological features. PATIENTS AND METHODS HPV types, gene promoter hypermethylation and protein expression were analysed by reverse line blot, methylation-specific polymerase chain reaction, and immunohistochemistry, respectively, in 24 penile squamous cell carcinomas. RESULTS HPV infection was detected in 11 of 24 cases (46%), and TSP-1, RASSF1-A and p16 genes were hypermethylated in 46%, 42% and 38% of the tumours, respectively. TSP-1 hypermethylation was associated with unfavourable histological grade (grade 3; P = 0.033), vascular invasion (P = 0.023), weak expression of TSP-1 protein (P = 0.041), and shorter overall survival (P = 0.04). TSP-1 expression was not associated with microvessel density. However, RASSF1-A hypermethylation was more frequent in T1 tumours (P = 0.01), and p16 hypermethylation was not associated with any of the tested variables except for absence of p16 expression (P = 0.022). CONCLUSION In summary, the epigenetic inactivation of TSP-1 and RASSF1-A genes is associated with pathological variables and seems to be of prognostic significance in penile cancer.

Abstract
Knowledge about the burden of Human Papillomavirus (HPV) infections in Sub-Saharan Africa is very limited. We collected cervical samples from 262 women from the general population and 241 tumor samples from women with invasive cervical cancer in Mozambique and tested them for HPV genotyping by the SPF(10)-LiPA(25) PCR system. Among the 195 women without cervical abnormalities by cytology HPV prevalence was 75.9%. In this group of women, the most frequently identified HPV types among HPV-positive women were in descending order of frequency: HPV51 (23.6%), HPV35 (19.6%), HPV18 (14.2%), HPV31 (13.5%) and HPV52 (12.8%). In women with cervical cancer HPV DNA detection was 100%. The type-specific distribution of the most frequent types in descending order of frequency was: HPV16 (47.0%), HPV18 (31.3%), HPV51 (14.8%), HPV52 (14.3%), HPV45 (12.6%), HPV35 (10.4%), HPV33 (4.8%) and HPV31 (2.6%). HPVs 16/18 and HPVs 16/18/31/45 were detected in 71.7% and 80.9% of cervical cancer tissue, respectively. While HPVs 51 and 35 were the two most common types in cytologically normal women in Mozambique, HPVs 16 and 18 remained the two most frequently identified types in cervical cancer. The introduction of an efficacious HPV 16/18 vaccine could potentially prevent the occurrence of 72% of cervical cancer cases and up to 81% of the cases if full cross-protection against HPVs 31 and 45 is assumed.

Abstract
We studied whether Fas-receptor (Fas-R; CD95) expression, single-nucleotide polymorphisms (SNPs) in the Fas promoter region, and/or Fas-ligand (Fas-L) production could determine individual susceptibility to cervical cancer progression. The clinicopathologic features of 38 patients with cervical squamous carcinomas (22 stage I, 8 stage II, and 8 stage III+) were reviewed and related with: (a) Fas-R expression by immunohistochemistry; (b) Fas-R SNPs at -670 and -1377 locations by restriction fragment length polymorphism and DNA sequencing; and (c) Fas-L expression by immunohistochemistry. Overall and disease-free survival curves showed significant differences in relation to stage (p < 0.001). Fas-R was identified in 20 of 38 (52.6%) tumors without statistical differences in survival, stage, or Fas-L overproduction. Fas-R GG genotype was more common than expected in advanced tumors (p = 0.065). The Fas-R-1377A allele and AA genotype were unrelated with survival, stage, or Fas-R expression. Fas-L overproduction was detected in 20 of 38 (52.6%) tumors; it was more frequent in advanced-stage tumors and was inversely related to survival (p = 0.03) and decrease in host inflammatory response (p = 0.01). Fas-R expression by tumor cells seems unrelated to stage or lymphoid infiltrate. Tumor production of Fas-L may represent an attempt to destroy the host's lymphocytic reaction.

Abstract
PURPOSE Primary chemotherapy brings the opportunity for an early and accurate assessment of response and offers an ideal model to search for new predictors of response. HER-2/neu is one of the most studied genes for this purpose. PATIENTS AND METHODS Her-2/neu was tested in a non-randomized series of 300 patients with operable breast carcinomas treated with primary CMF. Response was assessed by mammography. Disease-free survival (DFS) and overall survival (OS) were calculated after a mean follow-up of 116 months. Statistical analysis was performed to study the association between HER-2/neu status and response to CMF. RESULTS Overexpression/amplification was found in 23.66% cases. Univariate analysis showed that response was similar in HER-2/neu positive and negative tumors (51.38 vs. 47.36%, P = 0.6). Triple negative tumors (ER, PR and HER-2/neu negative) presented the highest response rate (64.9%). By multivariate analysis, response was significantly correlated to higher nuclear grade and negative estrogen receptor status (P = 0.02 and 0.007, respectively). Patients with HER-2/neu positive tumors presented shorter survival rates (P = 0.06). Patients with response to CMF showed a better survival over non-responders independent of Her-2/neu status. Patients with the combination of response to CMF and Her-2/neu negative tumors presented the best outcome. On the other hand, the association of no response to CMF and positive Her-2/neu score was statistically related to poor DFS and OS. CONCLUSIONS CMF indication is independent of Her-2/neu status.
