Abstract
INTRODUCTION p16 immunostaining is considered as a surrogate marker for human papillomavirus (HPV)-related head and neck squamous cell carcinomas (HNSCC). Herein, the utility of p16 is evaluated in cytology specimens. MATERIAL AND METHODS The electronic data of a large academic institution was searched for cytology cases accompanied by p16 (2014-2018). Cases were categorized based on body sites. P16 staining was quantified (negative [0%], focal/patchy, or diffusely positive [>70%]). HPV testing was correlated where available. RESULTS A total of 372 cases were included (male:female, 239:133). The largest differences in application of p16 between men and women were in head/neck cases (209 versus 59) and the abdominal cases (1 versus 33), respectively. p16 diffuse staining is seen in most squamous cell carcinomas, small cell carcinomas, and gynecologic serous carcinomas. p16 expression was patchy or negative in most adenocarcinoma, neuroendocrine carcinoma, spindle cell neoplasms, and benign conditions. HPV testing was done on 217 cases including 138 cases with strong p16 (127 HPV+/11 HPV-), 20 cases with focal/patchy P16 staining (6 HPV+/14 HPV-) and 59 cases with negative p16 staining (3 HPV+/56 HPV-). CONCLUSIONS Diffuse p16 staining aids in the diagnosis of HPV-related carcinomas, particularly HPV-related HNSCC, across the body and according to sex. In contrast, focal/patchy p16 staining does not correlate with HPV status across various body sites. In conclusion, intensity of p16 matters and should be correlated with cytomorphology, clinical history, and ancillary studies (eg, p40 immunostaining) for an accurate diagnosis and preventing diagnostic pitfalls.

Abstract
OBJECTIVE This study aimed to evaluate the association between human papillomavirus infection and salivary gland tumours in a Scottish cohort. METHODS Specimens from a range of salivary gland tumours operated on between 1997 and 2012 were studied. A tissue microarray constructed from tissue blocks was subjected to p16INK4 (cyclin-dependent kinase inhibitor 2A) immunohistochemistry and in situ hybridisation using probes specific for human papillomavirus, including types 16 and 18. RESULTS A total of 61 tumours (benign and malignant) were deemed suitable for the study. p16INK4 staining yielded three (4.9 per cent) positive samples: one small cell carcinoma, one squamous cell carcinoma and one poorly differentiated carcinoma. Human papillomavirus in situ hybridisation demonstrated a positive signal in the latter sample only (1.6 per cent). CONCLUSION This study demonstrated a very low human papillomavirus detection rate in salivary gland tumours. It can therefore be concluded that human papillomavirus infection is unlikely to play a role in salivary gland neoplasia. Rare human papillomavirus positive cases should be carefully evaluated to exclude the possibility of a metastatic lesion.

Abstract
OBJECTIVE To observe the infection of the high risk human papillomavirus (HPV) in the specimen of the small cell neuroendocrine carcinoma of the uterine cervix (SCNEC). METHODS We extracted the nucleic acids in the formalin-fixed and paraffin-embedded specimen from a 33-year-old patient diagnosed as small cell neuroendocrine carcinoma of uterine cervix and detected the HPV genotype with the nested PCR. RESULTS We identified HPV18, a high-risk genotype, in the specimen. CONCLUSION The HPV detection with the nested PCR was available for identification of the HPV genotype(s) in the paraffin-embedded specimens of small cell neuroendocrine carcinoma of the uterine cervix with a high accuracy and sensitivity.

Abstract
Besides its well-known role in cervical carcinoma, HPV is also suggested to be involved in lung cancer development. A number of authors have been investigating the presence of HPV in histological materials. We used routine bronchial aspirates from 84 patients with lung carcinoma for DNA extraction and then performed polymerase chain reaction for high-risk HPV types 16, 18 and 33. The results were compared to those obtained from buccal and eyelid mucosa. Only three patients were positive for HPV in bronchial aspirates: one for HPV 16 type, one for HPV 18 type, and one for HPV 33. Our data indicated the low prevalence of HPV in patients with lung carcinomas in Croatia, therefore it seems unlikely that HPV contributes to the development of lung carcinomas in this region.

Abstract
AIMS Small cell carcinoma of the ovary, hypercalcaemic-type (SCCOH) is morphologically similar to small cell carcinomas from other sites. The aims of this study were to (i) determine if a biomarker panel would distinguish small cell carcinomas of the ovary, cervix (SCCCx) and lung (SCCLu) and (ii) potentially determine the histogenesis of SCCOH. METHODS AND RESULTS Nine ovarian small cell carcinomas (seven hypercalcaemic type; two pulmonary type), eight SCCCx and 22 SCCLu were immunostained for thyroid transcription factor (TTF)-1, WT-1, p16, cKIT and OCT3/4; a subset of cases were tested for human papillomavirus (HPV). WT-1 was diffusely positive in 6/7 SSCOH versus two of 33 other small cell carcinomas (P <or= 0.001). TTF-1 was diffusely positive in 20/22 SCCLu and 1/8 SCCCx, and negative in all SCCOH. p16 and cKIT demonstrated variable patterns of immunoreactivity in all cases. HPV was identified in 5/6 SCCCx; SCCOH and SCCLu were negative for HPV. CONCLUSIONS Combined staining with WT-1 and TTF-1 will distinguish SCCOH from SCCLu and SCCCx with a sensitivity of 86% and specificity of 97%. HPV is specific for tumours of cervical origin, but p16 immunohistochemistry is not useful for this purpose. The presence of diffuse WT-1 supports a Müllerian origin for SCCOH, whereas the absence of cKIT and OCT3/4 argues against a germ cell origin.

Abstract
The JC virus (JCV) infects a large proportion of the population world wide and can cause progressive multifocal leucoencephalopathy in the context of immunodeficiency. Recent reports provide evidence that it may also be oncogenic. Here, JCV was examined by targeting its T-antigen in lung carcinomas (n=103) and normal lung tissues (n=18) by nested-PCR followed by Southern blot, real-time PCR, immunohistochemistry, in situ hybridization and in situ PCR. Additionally, expression of Ki-67, caspase-3, beta-catenin, p53, and Rb was analysed by immunohistochemistry on tissue microarrays of lung carcinomas. Copy numbers of JCV were compared with clinicopathological features. Normal lung tissue was positive significantly less frequently, and contained a lower copy number of JCV than lung carcinomas (p<0.05), and copies were lower in lung adenocarcinomas than in squamous, small or large cell carcinomas (p<0.05). In situ PCR and immunolabelling revealed JCV positivity in the nuclei of lung carcinoma cells. The JCV copy number correlated closely with sex, and expression of Ki-67 and membrane beta-catenin (p<0.05), but not with age, tumour size, pleural invasion, lymph node metastasis, expression of caspase-3, cytoplasmic beta-catenin, p53 or Rb, prognosis, smoking or cancer family history (p>0.05). Age and UICC staging were independent prognostic factors for lung carcinoma patients. These data suggest that JCV may be involved in lung carcinogenesis, especially in tumour types other than adenocarcinoma. Lung carcinomas with higher JCV copy numbers display high proliferation and down-regulation of cell adhesion mediated by membrane beta-catenin.

Abstract
The present study describes 31 clinical cases of neuroendocrine cervical carcinoma (NECC) treated at Mackay Memorial Hospital between January 1, 1991 and October 31, 2003. There are two cases of atypical carcinoid tumor (ACT), four cases of large-cell neuroendocrine carcinoma (LCNEC), and 25 cases of small-cell neuroendocrine carcinoma (SCNEC). Overall survival did not differ significantly in relation to surgery, tumor histology, age, FIGO stages, chemotherapeutic regimens or lymph node involvement. The specimens available did not permit HPV (human papillomavirus)-DNA analysis in 5 cases (5/31, 9.7%). The HPV viral infection was absent in 8 cases (8/31, 26%); 17 cases of HPV-18 (17/31); and 1 case of HPV-16 (1/31). The prognosis between mixed and pure type histologic patterns is not significant. The mean survival time for all patients was 32.3 months. The 2-year and 5-year survival rates were 54.8% and 31.5% for all patients. The results of this study reaffirm the biologically aggressive nature of this rare malignancy, its low survival rate, and its very unpredictable prognostic factors. Effective treatments of neuroendocrine cervical tumor still remain inconclusive. Further efforts are still required to identify prognostic factors for this uncommon disease.

Abstract
The presence of human papillomavirus (HPV) genome in lung carcinomas has been reported worldwide but its frequency varies from country to country. We examined HPV genome in 36 lung carcinomas, consisting of 14 squamous cell carcinomas, 13 adenocarcinomas, and 9 small cell carcinomas, collected from Colombia, Mexico and Peru. PCR analysis using GP5+/GP6+ primers, combined with Southern blot hybridization, found the presence of HPV genome in 10 (28%) of 36 cases. This percentage is similar to the value of 22% reported by Syrjänen, who conducted a meta-analysis of nearly 2500 lung carcinomas examined to date. Genotype analysis revealed that the most predominant genotype was HPV-16 (7 cases), followed by HPV-18 (2 cases) and HPV-33 (1 case). HPV-16 was more frequently found among female than male cases (P=0.008) but was not detected in any adenocarcinoma cases. On the other hand, HPV-18 and HPV-33 were detected only among male cases. These HPV genotypes were detected only in adenocarcinomas, and all the HPV genotypes detected in this histological type were HPV-18 or HPV-33. The frequency of HPV-16 positive cases among all the HPV positive cases differed in the sexes (P=0.033) and differed in the three histological types (P=0.017). The presence of HPV tended to be more frequent in well-differentiated tumors when squamous cell carcinomas and adenocarcinomas were combined. However, it was not statistically significant (P=0.093). Neither p16 nor p53 expression in carcinoma cells was related to the proportion of HPV-positive cases. In conclusion, high-risk HPV DNA was detected in 28% of lung carcinomas. The predisposition of HPV-16 to female cases and to non-adenomatous carcinomas warrants further investigation.

Abstract
Small cell carcinomas (SmCCs) of the uterine cervix are rare tumors. The knowledge regarding protein expression of several checkpoint candidates of cell cycle regulation is limited. Surgically treated SmCCs were selected from our files for immunohistochemical staining (neuroendocrine markers, p53, p16, p14, and cyclin D1). Polymerase chain reaction analysis, using general primers, was performed for human papillomavirus analysis. Nine of 677 tumors (1.3%) were classified as SmCCs after Grimelius staining (8/9 tumors positive) and immunohistochemical reaction against neurone-specific enolase, chromogranin A, synaptophysin (7/9 positive tumors), and CD 56 (8/9 positive tumors). All specimens were positive for at least two of the above. Two SmCCs were p53 positive and one case was p14 positive. Cyclin D1 staining was completely negative. All cases showed strong nuclear and/or cytoplasmic p16-immunostaining. Seven tumors represented human papillomavirus positivity for high-risk types. Four patients died of the tumor after a median time of 36.7 months (range, 15-56 months), representing a 5-year survival rate of 56%. The results suggest that p16 is up-regulated or accumulated in the SmCCs of the uterine cervix, probably caused by infection with human papillomavirus. p14 inactivation is of high prevalence in SmCCs and detection rate of p53 is similar to other histologic types of cervical carcinomas.

Abstract
The human polyomavirus JCV, the etiological agent of progressive multifocal leukoencephalopathy, has been associated with primitive neuroectodermal tumors and various glial-derived tumors, including glioblastoma multiforme (GBM). Here we describe the unique clinical case of a 54-year-old man who presented with headaches, hemiparesis and drowsiness. T1 and T2 magnetic resonance images revealed a large solid tumor with a cystic component located in the right temporal lobe, with extension into the parietal lobe. Histologically, the tumor was composed of two areas, a main area of large neoplastic cells with pleomorphic atypical nuclei and abundant cytoplasm, which by immunohistochemistry was reactive for glial fibrillary acidic protein, mixed with several foci of poorly differentiated tumoral cells with elongated nuclei and scant cytoplasm, negative for GFAP, but robustly immunoreactive for synaptophysin and phosphoneurofilaments. Results from PCR in laser capture microdissected cells from both areas of the tumor revealed the presence of DNA sequences corresponding to the early, late and control regions (CR) of the JCV genome and expression of JCV proteins T-antigen and Agnoprotein in both phenotypes. No evidence for capsid protein was observed, excluding productive viral infection. Sequencing demonstrated the presence of the JCV Mad-1 strain with distinct point mutations in the CR of isolates from both, GBM and small cell architectural areas. The presence of JCV DNA sequences and expression of viral proteins further reinforces the role of the widely spread human neurotropic virus in early transformation and in the development of brain tumors.

Abstract
We examined whether Epstein-Barr virus (EBV) infection plays a role in cervical carcinogenesis in Korean women. EBV infection was examined using polymerase chain reaction (PCR) with two different primer pairs flanking the BamHI "W" fragment of EBV and by EBV-encoded small RNAs (EBER) in situ hybridization in various histologic types of cervical cancer, including 17 cases of squamous cell carcinoma, 36 cases of adenocarcinoma, and 3 cases of small-cell carcinoma. We also evaluated 20 cases of cervical intraepithelial neoplasia and 20 cases of normal uterine cervix. One case of squamous cell carcinoma and three cases of cervical intraepithelial neoplasia were positive for EBV DNA using PCR, but EBER in situ hybridization analysis showed that none of the PCR-positive cases expressed EBER. EBV DNA was not found using PCR in any of the 20 normal uterine cervices. From our results, EBV infection does not seem to play a role in cervical carcinogenesis in Korean women.

Abstract
We investigated a series of 122 cases of small cell lung carcinomas and non-small cell lung carcinomas for the presence of several viruses that are known to be oncogenic in humans. Thus, viral genomes (DNA) and/or RNA transcripts and/or proteins of human papillomaviruses (HPV) 16, 18, 31, 33, 51, Epstein–Barr virus (EBV), human herpesvirus 8 (HHV-8), human cytomegalovirus (HCMV) and simian virus 40 (SV40) were investigated on tissue sections (prepared in tissue microarrays) with different techniques of immunohistochemistry and in situ hybridisation. None of the cases displayed a single positive tumour cell for all the viruses tested whatever the technique applied. Of note, in five cases of tumours with lymphoid infiltrates, we detected scattered EBV (EBER)-positive bystander lymphocytes. In three cases, a faint nuclear staining was found with the anti-latent nuclear antigen/LANA1 (HHV-8) antibody. These cases were checked by PCR with two sets of primers (orf 26 and orf 75) and remained negative for this latter virus. Taken together, our data strongly suggest that the conventional human oncogenic viruses (HPV, EBV, HCMV, HHV-8 and SV40) are unlikely to play some role in the development of lung carcinomas.

Abstract
Jaagsiekte retrovirus (JSRV) causes ovine pulmonary adenomatosis (OPA) that resembles bronchioloalveolar carcinoma (BAC) in humans. To test the possible role of JSRV in human diseases, DNA specimens from 103 individuals either healthy or suffering from lung carcinomas were analyzed for JSRV sequences. orf-x sequences were detected in 19 of 64 samples and gag-prt sequences in 4 of 38 samples, predominantly in individuals from Africa. Sequences obtained from orf-x amplimers varied in-between each other and differed from control endogenous ovine JSRV sequence. No association with lung cancer was found. This is the first report of JSRV-like sequences detected in humans.

Abstract
Small cell carcinomas of the uterine cervix are rare tumors with an aggressive behavior. Although these tumors can exhibit neuroendocrine differentiation, the criteria for neuroendocrine differentiation are subjective and not well defined. In this study, the authors tentatively defined small cell neuroendocrine carcinoma (SCNEC) as a tumor composed of small cells with at least two of the following: argyrophilic cytoplasm, chromogranin A immunoreactivity, and synaptophysin immunoreactivity. We found 10 cases fulfilling these requirements. Five of the 10 tumors were composed mainly of small ("oat") cells and 5 of mainly larger "intermediate" cells. The majority of both subtypes showed an insular pattern. Three of the 10 SCNECs were pure, whereas the other seven were mixed with adenocarcinoma and/or squamous cell carcinoma or cervical intraepithelial neoplasia. In addition to the definitional markers noted earlier, the tumors were immunoreactive for serotonin (6 cases), somatostatin, gastrin, glucagon, and pancreatic polypeptide. No tumors were immunoreactive for cytokeratin 20. Human papillomavirus (HPV)-18 was detected in all of the pure tumors and both the SCNEC and adenocarcinomatous components in four of the mixed tumors. No other types of HPV were detected. The tumors showed a relatively low frequency of loss of heterozygosity for representative tumor suppressor gene sites; p53 mutations were found in only one case.

Abstract
Epstein-Barr virus infection has been associated with lymphoepithelioma-like carcinoma of the lung in Asian patients. Recently, Epstein-Barr virus proteins or genomic DNAs were detected in pulmonary squamous-cell carcinoma, adenocarcinoma, and undifferentiated small-cell carcinoma in American patients. We studied 23 cases of small-cell carcinoma of the lung for evidence of Epstein-Barr virus infection by in situ hybridization, immunohistochemistry, and polymerase chain reaction methods. Of the 23 cases, 13 cases were primary small-cell carcinoma of the lung and 10 cases were metastatic small-cell carcinoma of the lung to the brain (one case), liver (two cases), and lymph nodes (seven cases). None of the 23 cases was positive for Epstein-Barr virus-encoded small nonpolyadenylated RNA (EBER)-1 by in situ hybridization. By immunohistochemistry, eight cases showed focal positivity for Epstein-Barr virus nuclear antigen-1. The positive immunostaining was focal and was observed in tumor cells, vascular endothelial cells, and lymphocytes, suggesting nonspecific staining. None of the 23 cases was positive for the transactivating immediate-early BZLF1 (ZEBRA) and latent membrane protein (LMP-1). Only one case was positive for the BamHI W region and LMP-1 gene by polymerase chain reaction assay. Some tumor cells in the BamHI W region positive case were also positive for Epstein-Barr virus nuclear antigen-1. Our study indicates that rare cases of American small-cell carcinoma of the lung may contain Epstein-Barr virus-infected cells, but it is unlikely that Epstein-Barr virus plays a role in the tumorigenesis of small-cell carcinoma of the lung.

Abstract
Carcinogenesis of cervical cancer has been investigated, and p16(INK4a) overexpression in squamous cell carcinoma of the cervix has been reported as a result of infection by human papillomavirus (HPV) (eg, HPV 16), and the consequence of the retinoblastoma (Rb) protein inactivation by HPV E7 protein. However, to our knowledge, there have been no studies on the relation between p16(INK4a) overexpression associated with HPV and small cell carcinoma of the cervix, which behaves more aggressively clinically than squamous cell carcinoma. The purpose of this study was to determine whether p16(INK4a) is overexpressed in small cell carcinoma, and if p16(INK4a) is overexpressed, the types of HPV that are related to this cancer. We reviewed 10 cases of small cell carcinoma and examined them for p16(INK4a) overexpression by immunohistochemistry. We also performed HPV typing with polymerase chain reaction (PCR)-sequencing analysis and in situ hybridization and found that p16(INK4a) was overexpressed in every case. PCR-sequencing analyses revealed that all cases were HPV-positive and that 9 cases were positive for HPV 18. Five of the 9 cases positive for HPV 18 were also positive by in situ hybridization and yielded a punctate signal, considered to represent the integrated form. In conclusion, p16(INK4a) was overexpressed and HPV 18 was frequently detected in an integrated form in small cell carcinoma. Therefore, inactivation of Rb protein by HPV 18 E7 protein may be associated with carcinogenesis of small cell carcinoma the same as inactivation of Rb protein by HPV 16 E7 protein is associated with carcinogenesis of squamous cell carcinoma.

Abstract
OBJECTIVE To describe the thin-layer cytology findings of small cell carcinoma of the low female genital tract, with histologic correlation and human papillomavirus (HPV) genotyping. STUDY DESIGN The authors reviewed the clinical findings, thin-layer cytology and histologic features of small cell carcinoma of the lower female genital tract (cervix or vagina) occurring in three postmenopausal Chinese women at Pamela Youde Nethersole Eastern Hospital, Hong Kong, over a four-year period, from January 1998 to December 2001. Molecular techniques for HPV screening and genotyping using the polymerase chain reaction and restriction fragment length polymorphism were employed on the cytologic specimens. RESULTS The thin-layer preparations were of moderate to high cellularity. There were loose aggregates of or isolated small round cells with a high nuclear/cytoplasmic ratio, thin but irregular nuclear membrane, hyperchromatic nuclei, inconspicuous nucleoli and scanty cytoplasm. Tumor cell cannibalism was commonly found. Small groups of tumor cells with nuclear molding were noted. There was also obvious tumor diathesis in the background. The necrotic debris was admixed with isolated small round cells, apoptotic bodies and nuclear dust. Associated koilocytosis or squamous intraepithelial lesions were not seen. Histologic examination of the tumor biopsies showed classic features of small cell carcinoma associated with squashing artifacts and vascularized stroma. Molecular analysis revealed the presence of HPV DNA (either type 18 or 16) in all the three liquid-based cytology samples. CONCLUSION While the cytomorphologic features of small cell carcinoma of the cervix or vagina in thin-layer preparations are slightly different from those in conventional smears, due mainly to the absence of smearing effect, recognition of the subtle but characteristic appearance can enhance the accuracy of the cytologic diagnosis. The association between HPV and primary small cell carcinoma of the lower female genital tract was confirmed by this study.

Abstract
BACKGROUND AND OBJECTIVES In situ polymerase chain reaction (ISPCR) promises to considerably enhance our ability to detect a few copies of target nucleic acid sequences in fixed tissues and cells. The aim of this study was to investigate cervical carcinoma to determine the human papillomavirus (HPV) types on paraffin-embedded tissue sections by ISPCR and standard in situ hybridization. The results will correlate the morphological characteristics of lesions with viral typing results. METHODS This study examined prevalence of HPV 16 and 18 DNA in biopsies from 85 cervical cancer patients by ISPCR, employing HPV 16, 18 consensus primers. There are 45 patients with squamous cell carcinomas, 13 with adenocarcinoma, 2 with adenosquamous carcinomas, 3 with small cell carcinomas, and 22 carcinoma in situ. The relation between the types of HPV detected, tumor type, and clinical stage were analyzed. RESULTS Fifty-two of 85 biopsies were HPV 16- or 18-positive, HPV 16 being the most prevalent type. Squamous cell carcinoma had a high prevalence of HPV 16 and adenocarcinoma had a high prevalence of HPV 18. HPV 18 was the predominant type among high clinical stage (III-IV) cases while HPV 16 and mixed HPV 16 with HPV18 were significantly correlated with low clinical stage (0-I-II). CONCLUSION Our results indicate that certain malignant cervical tumor phenotypes and stages correlate with specific HPV type, and that ISPCR is a sensitive and fast method to detect HPV in these patients.

Abstract
Several reports have suggested that there is an increased incidence of lung cancer amongst the HIV positive population. All cases of lung cancer reported in this group to date were in patients known previously to be HIV positive. We now report a case of AIDS presenting with small cell lung cancer. Unexpectedly severe pancytopenia and immunosuppression after combination chemotherapy revealed the underlying diagnosis. The prognosis in such cases is very poor, but it is important to establish the correct diagnosis in order for patients to make informed treatment decisions and to allow potentially life-saving treatment of their sexual partners.

Abstract
Cellular immunity plays a major role in controlling human papilloma virus infection and development of cervical carcinoma. Mononuclear cell infiltration possibly due to the action of chemokines becomes prominent in the tumor tissue. In fact, the macrophage chemoattractant protein-1, MCP-1, was detected in cervical squamous cell carcinoma in situ, whereas absent in cultured cells. From this, unknown environmental factors were postulated regulating chemokine expression in vivo. In this study, we show high CD40 expression on cervical carcinoma cells and CD40 ligand (CD40L) staining on attracted T cells in tumor tissue, suggesting a paracrine stimulation mechanism via CD40L-CD40 interactions. We therefore investigated chemokine synthesis in nonmalignant and malignant human papilloma virus-positive cell lines after CD40L exposure. Constitutive expression of MCP-1, MCP-3, RANTES, and IFN-gamma-inducible protein-10 was almost undetectable in all cell lines tested. CD40L was able to induce MCP-1 production; however, despite much higher CD40 expression in malignant cells, MCP-1 induction was significantly lower compared with nontumorigenic cells. After sensitization with IFN-gamma, another T cell-derived cytokine showing minimal effects on CD40 expression levels, CD40 ligation led to a more than 20-fold MCP-1 induction in carcinoma cell lines. An even stronger effect was observed for IFN-gamma-inducible protein-10. Our study highlights the synergism of T cell-derived mediators such as CD40L and IFN-gamma for chemokine responses in cervical carcinoma cells, helping to understand the chemokine expression patterns observed in vivo.

Abstract
In previous studies we have reported the sensitisation of human tumour cells to gamma irradiation and chemotherapeutic drugs upon infection with the human non-pathogenic adeno-associated virus type 2 (AAV-2) in vitro and in vivo. Treatment of small cell lung cancer (SCLC) is consistently hampered by relapses due to the selection of chemotherapy-resistant cell clones. Hence, we were interested to test whether selection of chemotherapy-resistant SCLC cells might be reduced or even prevented if chemotherapy is applied in combination with AAV-2 infection. In vitro proliferation assays indicated that the number of proliferating cells, after combined treatment with cisplatin and etoposide, can be significantly reduced by concomitant AAV-2 infection, as compared with treated but non-infected controls. H446 SCLC cells, which show resistance to etoposide/cisplatin chemotherapy (compared with a cell line which was never chemotherapeutically treated before, like NCI-H209) were significantly more sensitive after AAV-2 infection, suggesting that the therapeutic efficacy of chemotherapy in SCLC can be enhanced even if the cells are already relatively resistant to chemotherapy. Similarly, in vivo growth of tumours induced by inoculation of SCLC cells into immunocompromised nude mice was reduced more efficiently in AAV-2-infected animals compared with tumours in mice treated with chemotherapeutic drugs alone. These data extend and further support our previous reports on AAV functions which might be useful in improving the efficacy of chemotherapeutic drugs used in human cancer treatment.

Abstract
Direct gene transfer to solid tissues or metastatic cancer cells requires vectors capable of in vivo transduction to specific cells. The predominant retroviral vectors of murine origin are inactivated by human complement, which precludes their use in vivo. Such inactivation does not take place with vectors based on human retroviruses. Murine retroviral vectors are also limited to proliferating cells, which human retroviruses are not. In this study we examined whether or not a vector using components from the human retroviruses HIV-1 and HTLV-1 could infect small-cell lung cancer cells and resting CD34+ hematopoietic stem cells. While HIV-1 itself was unable to infect cells lacking the CD4-membrane molecule, chimeric viral particles (pseudotype virus) with HIV-1 genome and HTLV-1 envelope components were able to infect both CD4-containing lymphocytic cells, CD4-negative tumour cells and hematopoietic stem cells. After infection with the pseudotype vector, the RNA genome was reverse transcribed and integrated. Transduction efficiency and gene expression under the HIV-1 LTR promoter in both tumour and stem cells were found to be of a similar or greater magnitude than in lymphocytic cells. These results suggest that gene transfer targeting proliferating as well as resting cells in vivo may be realized using components from human retroviruses.

Abstract
BACKGROUND Recently, it has been proposed that human papilloma virus (HPV) infection may play a role in the carcinogenesis of bladder urothelial malignancy. However, there is still controversy about the prevalence of HPV in such malignancies. With similar techniques of in situ hybridization (ISH) or polymerase chain reaction (PCR), either high or rare frequency have been detected. To evaluate the prevalence of HPV in the urothelial malignancies based on presentations here, 118 cases of urothelial malignancies were analysed, including those of the renal pelvis and ureter which have rarely been reported before. METHODS Non-isotopic ISH technique was used to detect HPV on paraffin sections, including 51 bladder transitional cell carcinoma (TCC), 48 renal pelvic/ureter TCC, 5 bladder adenocarcinoma, 3 bladder small cell carcinoma, 2 bladder undifferentiated carcinoma, 1 multiple synchronous pelvic and ureteric squamous cell carcinoma (SCC) and 8 bladder SCC. An FITC-labelled probe of wide spectrum HPV was used for screening, and probes of HPV 6/11, 16, 18, 31, 33 were used for typing. RESULTS By the technique of ISH, wide spectrum HPV was detected in only three of the eight cases of bladder SCC. Of the three positive cases, two were subsequently shown to be uterine cervical SCC with bladder invasion. Therefore, HPV was positive in only one case of primary bladder SCC, occurring in a patient with systemic lupus erythematosus under steroid and cyclophosphamide therapy. Further subtyping was negative for HPV 6/11, 16, 18, 31, and 33. The result indicated that the positive staining by wide spectrum probe was caused by types 30, 35, 45, 51, and/or 52. HPV was not detected in any of the 51 bladder TCC, 48 renal pelvic/ ureter TCC, 5 bladder adenocarcinoma, 3 bladder small cell carcinoma, and 2 bladder undifferentiated carcinoma. CONCLUSIONS The results are in agreement with the majority of recent reports which suggest that HPV is unlikely to be involved in the etiology of urothelial malignancies; however, it seems probable that immunosuppressed patients are at greater risk for HPV-associated bladder SCC.

Abstract
To determine the clinical relevance of human papillomavirus (HPV) integration and E2 function suggested by in vitro studies, we investigated 50 patients with HPV 16-positive primary cervical carcinoma (stage Ib-IV) diagnosed and treated at one institution. The physical state of HPV was determined by colorimetric in situ hybridization and was not found to vary by stage. Overall, 62% of tumors had integrated HPV, 16% had episomal and 22% had both integrated and episomal. The E1/E2 region was evaluated by 8 separate polymerase chain reactions, which resulted in overlapping products. There was no significant variation in ability to amplify the E1/E2 region with stage. E1/E2 amplification correlated with physical state. Nearly all tumors with episomal or mixed HPV 16 DNA amplified all 8 E1/E2 fragments. Half of the tumors with integrated HPV 16 DNA failed to amplify one or more E1/E2 fragments. Disruptions were most frequent in the E2 region. For all 46 patients receiving curative therapy, the Kaplan-Meier estimate of disease-free survival was determined for those whose primary tumors had amplifiable E2 compared with those lacking one or more E2 DNA fragments. Disruption of E2 was associated with significantly shortened disease-free survival.

Abstract
Group C adenovirus is latent in human tissues and can malignantly transform cells. The purpose of this study was to investigate the association between this virus and lung cancer. We investigated latent adenoviral infection using the nested polymerase chain reaction and in situ hybridization in transbronchial biopsy specimens from patients with small-cell lung cancer and non-small-cell lung cancer. The polymerase chain reaction was performed on DNA extracts with two sets of primers directed at a 261-base-pair target sequence of the E1A region of the adenoviral genome. In situ hybridization was performed on histological sections using DNA representing the entire adenovirus type 5 genome. E1A target DNA was present in 11 (31%) of 35 cases of small-cell lung cancer but in none of the 40 cases of non-small-cell lung cancer (P < 0.01). Of the 11 cases found positive by PCR, 8 were positive for adenovirus DNA by in situ hybridization. Adenovirus was prominent in tumor cells in 5 of the 8 cases, and in normal epithelial cells in the 3 remaining cases. Adenovirus DNA was not detected by in situ hybridization in specimens in which E1A DNA was not detected by the polymerase chain reaction. Small-cell lung cancer has mutations or deletions in the p53 and retinoblastoma genes more frequently than are found in non-small-cell lung cancer. Therefore, we speculate that adenovirus infection might participate in the pathogenesis of SCLC by producing mutation in these genes, rather than by inhibiting the function of these proteins.

Abstract
Human papillomaviruses (HPV) have been implicated in the pathogenesis of human squamous cell carcinoma, specially of cervical carcinomas. In previous studies concerning primary lung cancer, DNA of HPV subtypes was detected by in situ hybridization or polymerase chain reaction (PCR), up to 30% of the cases, namely in squamous cell carcinomas. A series of 31 frozen biopsies of lung carcinomas (surgical biopsies or through fiber optic bronchoscopy) were examined for the presence of HPV DNA by nested PCR. Primers for the two steps were type-specific primers (6/11-16 and 18; kit Amplicis-HPV) for the transforming region of HPV. HPV-DNA was found in five tumors: in two of 18 cases of squamous cell carcinoma (11%), in one of four cases of adenocarcinoma, in one of six cases of small cell carcinomas and in the unic case of neuro-endocrin carcinoma. No case of the two large cell undifferentiated carcinomas was positive. There were three cases of HPV 6/11, one case of HPV 16, and one sample positive for HPV 6/11 and HPV 18. No morphologic changes consistent with HPV lesions were observed. The frequency of 11% among the squamous cell carcinomas is near those found by previous studies (9 to 20% for HPV 6-11-16-18). For the first time, HPVs have been detected in neuro-endocrin tumors, and this have to be confirmed by studies of many more cases. So HPV might play a role as promoter in carcinogenesis of any types of lung carcinoma, although at a low frequency.

Abstract
Tumours express a variety of novel epitopes which represent potential immune targets, and thus clinically evident tumours are thought to have effectively avoided immune recognition and elimination. Transporters associated with antigen presentation (TAP) are thought to be responsible for conveying intracellular peptides into the endoplasmic reticulum for complex formation with class I MHC and subsequent recognition by cytotoxic T lymphocytes. In this study, we evaluated 79 human solid tumours and cell lines for genetic abnormalities in TAP1 that might have led to an acquired loss of antigen presenting ability. A novel sequence (R659Q) was discovered near the ATP binding site in a human small cell lung cancer (SCLC) cell line, H1436. This cell line is heterozygous for this allele, but only the R659Q allele is transcribed into RNA. Even though the R659Q protein is expressed, these cells act as if they were TAP deficient by peptide binding and antigen presentation studies, which are restored after transfection of a functional TAP1 allele. This is the first evidence for a naturally occuring protein structural defect resulting in defective peptide transport in a human solid tumour.

Abstract
Surgical samples from 40 cases of primary lung cancer were studied by in situ hybridization and polymerase chain reaction (PCR) to detect HPV-DNA in different types of lung cancer. In addition, PCR-RFLP was used to examine mutation of p53 exon 7. The results showed that HPV-DNA positive rate in lung cancer was 55% (22/40 cases), including SCLC (9/9 cases), squamous cell carcinomas (8/16 cases), and adenocarcinomas (5/12 cases). Amplification of p53 exon 7 was seen in 5 of 22 HPV-DNA positive cases. RFLP analysis showed that p53 exon 7 mutation was present in two cases with gene amplification. In HPV-DNA negatives there was only one case with exon 7 amplification but no mutation. SCLC and squamous carcinoma had higher HPV infection rate than other types of lung cancer. The results suggest some relation between HPV infection and p53 gene mutation.

Abstract
Human papillomaviruses (HPV) have been implicated in the pathogenesis of human squamous cell carcinoma, especially of cervical carcinomas. In two previous studies concerning squamous cell carcinomas of the lung, DNA of HPV subtypes 6/11/16/18 (and 31/33/35 for one study) was detected by in situ hybridization in 7% to 30% of the cases. A series of 31 frozen biopsies of lung carcinomas were examined for the presence of HPVDNA by nested polymerase chain reaction (PCR). Type-specific primers (6/11, 16 and 18; Amplicis HPV(R)) located in the E6 or E7 transforming region of HPV were used. HPV DNA was found in 2 of 18 cases (11%) of squamous cell carcinoma, in 1 of 4 cases of adenocarcinoma and in 2 of 7 cases of neuro-endocrine cancers. The two large cell undifferentiated carcinomas were HPV negative. There were three cases of HPV 6/11, one case of HPV 16, and one sample positive for HPV 6/11 and HPV 18. No any consistent morphologic change with HPV lesions could be observed whereas squamous metaplasia could be seen only in squamous cell carcinomas. The frequency of 11% among the squamous cell carcinomas is comparable to those previously reported in studies utilizing in situ hybridization. To our knowledge HPV DNA had never been detected previously in adenocarcinomas or neuro-endocrine tumors. This finding should be confirmed by the investigation of larger series, but suggests that HPV could play a role in carcinogenesis of different types of lung carcinoma, although at low frequency.

Abstract
The delivery of viral vectors to the brain for treatment of intracerebral tumors is most commonly accomplished by stereotaxic inoculation directly into the tumor. However, the small volume of distribution by inoculation may limit the efficacy of viral therapy of large or disseminated tumors. We have investigated mechanisms to increase vector delivery to intracerebral xenografts of human LX-1 small-cell lung carcinoma tumors in the nude rat. The distribution of Escherichia coli lacZ transgene expression from primary viral infection was assessed after delivery of recombinant virus by intratumor inoculation or intracarotid infusion with or without osmotic disruption of the blood-brain barrier (BBB). These studies used replication-compromised herpes simplex virus type 1 (HSV; vector RH105) and replication-defective adenovirus (AdRSVlacZ), which represent two of the most commonly proposed viral vectors for tumor therapy. Transvascular delivery of both viruses to intracerebral tumor was demonstrated when administered intraarterially (i.a.) after osmotic BBB disruption (n = 9 for adenovirus; n = 7 for HSV), while no virus infection was apparent after i.a. administration without BBB modification (n = 8 for adenovirus; n = 4 for HSV). The thymidine kinase-negative HSV vector infected clumps of tumor cells as a result of its ability to replicate selectively in dividing cells. Osmotic BBB disruption in combination with i.a. administration of viral vectors may offer a method of global delivery to treat disseminated brain tumors.

Abstract
To provide an accurate evaluation of the association of human papillomavirus (HPV) with lung cancer, 36 cases of lung cancer were analysed for HPV DNAs by polymerase chain reaction (PCR) with dot-blot and Southern blot analyses, and for the transcripts from the E6-E7 transforming region by in situ hybridisation (ISH). HPV-18 DNA was detected in three (8%) of 36 specimens; histologically, in one (10%) of 10 squamous cell carcinomas and two (9%) of 22 adenocarcinomas. Neither HPV-16 nor -33 DNA was detected in any cases examined. Expression of E6-E7 mRNA was confirmed in the cases which contained, HPV-18 DNA. HPV-18 may play an important role in the development and progression of cancer in some cases of both squamous cell carcinoma and adenocarcinoma of the lung.

Abstract
Genetic aberrations were examined to assess the possible roles that p53 and retinoblastoma susceptibility genes might have played in the development of small cell cervical carcinomas. Cervical cancer tissues from 12 patients with small cell cervical carcinoma that were free of human papillomavirus were analyzed. The presence of mutational alterations were examined by polymerase chain reaction-single-strand conformation polymorphism and by direct DNA sequencing. None of 12 small cell cervical carcinomas were found to contain mutations in regions of p53 and retinoblastoma susceptibility genes that were functionally important and where most mutations, in human tumors have been found. Furthermore, there was no evidence indicative of loss of heterozygosity of chromosome region 17p13 (in which p53 is located) in these tumors. These data seem to suggest that whereas mutant type of p53 and retinoblastoma susceptibility genes may exhibit "oncogenic" function in many human tumors, mutational inactivation of these genes may not be an important feature in the carcinogenic development of human papillomavirus-negative small cell cervical carcinomas.

Abstract
To investigate the possibility of human cytomegalovirus (HCMV) involvement in the aetiology of cervical carcinoma or in the development of a more clinically aggressive cancer cell phenotype, biopsies of cervical cancer from 103 women undergoing primary therapy for invasive (Stage Ia to IV) cervical cancer were investigated using a polymerase chain reaction (PCR) designed to detect sequences from the IE mtrII region of HCMV. PCR assays were also used on the same specimens to identify the presence of common human papillomavirus (HPV) types associated with cervical cancer (HPV 16, 18, 31, 33, 52, and 58). Of the 103 cancers examined, only 4 contained detectable HCMV DNAs, a proportion lower than that found by another Australian group investigating the cervical carriage of HCMV in women with normal cervices. In contrast, 89 of these cancers were positive for HPV DNA sequences, with HPV 16 (65/103) and HPV 18 (17/103) being most commonly detected. Three of the 4 HCMV-positive tumors were also positive for HPV 16 DNA. An examination of the relevant histopathological and clinical data revealed no evidence to support a contention that cancers positive for HCMV are associated with any unusual histologic cell types or with aggressive clinical behavior.
