Abstract
BACKGROUND Poor oral hygiene has been proposed to contribute to head and neck cancer (HNC) risk, although causality and independency of some indicators are uncertain. This study investigates the relationship of five oral hygiene indicators with incident HNCs. METHODS In a pooled analysis of 8925 HNC cases and 12 527 controls from 13 studies participating in the International Head and Neck Cancer Epidemiology Consortium, comparable data on good oral hygiene indicators were harmonized. These included: no denture wear, no gum disease (or bleeding), <5 missing teeth, tooth brushing at least daily, and visiting a dentist ≥once a year. Logistic regression was used to estimate the effects of each oral hygiene indicator and cumulative score on HNC risk, adjusting for tobacco smoking and alcohol consumption. RESULTS Inverse associations with any HNC, in the hypothesized direction, were observed for <5 missing teeth [odds ratio (OR) = 0.78; 95% confidence interval (CI) 0.74, 0.82], annual dentist visit (OR = 0.82; 95% CI 0.78, 0.87), daily tooth brushing (OR = 0.83, 95% CI 0.79, 0.88), and no gum disease (OR = 0.94; 95% CI 0.89, 0.99), and no association was observed for wearing dentures. These associations were relatively consistent across specific cancer sites, especially for tooth brushing and dentist visits. The population attributable fraction for ≤ 2 out of 5 good oral hygiene indicators was 8.9% (95% CI 3.3%, 14%) for oral cavity cancer. CONCLUSION Good oral hygiene, as characterized by few missing teeth, annual dentist visits, and daily tooth brushing, may modestly reduce the risk of HNC.

Abstract
In the Phase III PATRICIA study (NCT00122681), the human papillomavirus (HPV)-16/18 AS04-adjuvanted vaccine (Cervarix(®), GlaxoSmithKline Biologicals) was highly efficacious against HPV-16/18 infections and precancerous lesions in women HPV-16/18 deoxyribose nucleic acid (DNA) negative and seronegative at baseline. We present further data on vaccine efficacy (VE) against HPV-16/18 in the total vaccinated cohort including women who may have been exposed to HPV-16/18 infection before vaccination. In women with no evidence of current or previous HPV-16/18 infection (DNA negative and seronegative), VE was 90.3% (96.1% confidence interval: 87.3-92.6) against 6-month persistent infection (PI), 91.9% (84.6-96.2) against cervical intraepithelial neoplasia (CIN)1+ and 94.6% (86.3-98.4) against CIN2+ [97.7% (91.1-99.8) when using the HPV type assignment algorithm (TAA)]. In women HPV-16/18 DNA negative but with serological evidence of previous HPV-16/18 infection (seropositive), VE was 72.3% (53.0-84.5) against 6-month PI, 67.2% (10.9-89.9) against CIN1+, and 68.8% (-28.3-95.0) against CIN2+ [88.5% (10.8-99.8) when using TAA]. In women with no evidence of current HPV-16/18 infection (DNA negative), regardless of their baseline HPV-16/18 serological status, VE was 88.7% (85.7-91.1) against 6-month PI, 89.1% (81.6-94.0) against CIN1+ and 92.4% (84.0-97.0) against CIN2+ [97.0% (90.6-99.5) when using TAA]. In women who were DNA positive for one vaccine type, the vaccine was efficacious against the other vaccine type. The vaccine did not impact the outcome of HPV-16/18 infections present at the time of vaccination. Vaccination was generally well tolerated regardless of the woman's HPV-16/18 DNA or serological status at entry.

Abstract
BACKGROUND Previous analyses from a randomised trial in women aged 24-45 years have shown the quadrivalent human papillomavirus (qHPV) vaccine to be efficacious in the prevention of infection, cervical intraepithelial neoplasia (CIN), and external genital lesions (EGLs) related to HPV 6/11/16/18. In this report, we present end-of-study efficacy, safety, and immunogenicity data with a median follow-up time of 4.0 years. METHODS We enrolled 3819 24-45-year-old women with no history of cervical disease or genital warts in the past 5 years. Women received quadrivalent vaccine or placebo at day 1, and at months 2 and 6. Ascertainment of CIN/EGL was accomplished through Pap testing, genital inspection, and cervicovaginal sampling (every 6 months). The main analysis was conducted in a per-protocol efficacy population (that received three doses, was naive to the relevant HPV types at day 1, and remained free of infection through month 7). Efficacy was also estimated in other naive and non-naive populations. RESULTS Vaccine efficacy against the combined incidence of persistent infection, CIN/EGL related to HPV6/11/16/18 in the per-protocol population was 88.7% (95% CI: 78.1, 94.8). Efficacy for women who were seropositive and DNA negative for the relevant vaccine HPV type at the time of enrolment who received at least 1 dose was 66.9% (95% CI: 4.3, 90.6). At month 48, 91.5, 92.0, 97.4, and 47.9% of vaccinated women were seropositive to HPV 6/11/16/18, respectively. No serious vaccine-related adverse experiences were reported. CONCLUSIONS The qHPV vaccine demonstrated high efficacy, immunogenicity, and acceptable safety in women aged 24-45 years, regardless of previous exposure to HPV vaccine type.

Abstract
BACKGROUND The knowledge that persistent human papillomavirus infection is the main cause of cervical cancer has resulted in the development of assays that detect nucleic acids of the virus and prophylactic vaccines. Up-to-date and reliable data are needed to assess impact of existing preventive measures and to define priorities for the future. MATERIALS AND METHODS Best estimates on cervical cancer incidence and mortality are presented using recently compiled data from cancer and mortality registries for the year 2008. RESULTS There were an estimated 530,000 cases of cervical cancer and 275,000 deaths from the disease in 2008. It is the third most common female cancer ranking after breast (1.38 million cases) and colorectal cancer (0.57 million cases). The incidence of cervical cancer varies widely among countries with world age-standardised rates ranging from <1 to >50 per 100,000. Cervical cancer is the leading cause of cancer-related death among women in Eastern, Western and Middle Africa; Central America; South-Central Asia and Melanesia. The highest incidence rate is observed in Guinea, with ∼6.5% of women developing cervical cancer before the age of 75 years. India is the country with the highest disease frequency with 134,000 cases and 73 000 deaths. Cervical cancer, more than the other major cancers, affects women <45 years. CONCLUSIONS In spite of effective screening methods, cervical cancer continues to be a major public health problem. New methodologies of cervical cancer prevention should be made available and accessible for women of all countries through well-organised programmes.

Abstract
BACKGROUND Penile carcinoma is an uncommon and potentially mutilating disease with a heterogeneous aetiology. Several risk factors have been established for its development. Human papillomavirus (HPV) infection seems to play an important role in the development of a subset of these carcinomas and its presence is thought to be related to the histological type. HPV prevalence in penile tumours is reported to be associated to a variety of morphological changes. Its determination will provide a better estimate for HPV related cancer burden and its preventable fraction. METHODS A systematic and comprehensive literature review of the major penile cancer studies published from 1986 until June 2008 evaluating the HPV prevalence among the different histological types was carried out. RESULTS 31 studies including 1466 penile carcinomas were reviewed. Global HPV prevalence was 46.9%. Relative contribution was: HPV-16 (60.23%), HPV-18 (13.35%), HPV-6/11 (8.13%), HPV-31 (1.16%), HPV-45 (1.16%), HPV-33 (0.97%), HPV-52 (0.58%), other types (2.47%). Assessment of multiple infections contribution is limited due to study design. Basaloid and warty squamous cell carcinomas were the most frequent HPV-related histological types, but keratinising and non-keratinising subtypes also showed prevalence rates of around 50%. CONCLUSIONS About half of the penile tumours were associated with HPV 16-18 with little presence of other genotypes. Research on the mechanisms behind penile carcinogenesis is warranted. Available HPV vaccines are likely to be effective in penile tumours.

Abstract
Early age at first sexual intercourse (AFSI) has long been associated with an increased risk of invasive cervical carcinoma (ICC). Age at first pregnancy (AFP) and ICC have been investigated less, although AFSI and AFP are strongly interrelated in most developing countries. A pooled analysis of case–control studies on ICC from eight developing countries with 1864 cases and 1719 controls investigated the roles of AFSI, AFP, and ICC risk. Age at first sexual intercourse, AFP and age at first marriage (AFM) were highly interrelated and had similar ICC risk estimates. Compared with women with AFSI ⩾21 years, the odds ratio (OR) of ICC was 1.80 (95% CI: 1.50–2.39) among women with AFSI 17–20 years and 2.31 (95% CI: 1.85–2.87) for AFSI ⩽16 years (P-trend <0.001). No statistical interaction was detected between AFSI and any established risk factors for ICC. The ICC risk was 2.4-fold among those who reported AFSI and AFP at ⩽16 years compared with those with AFSI and AFP at ⩾21 years. These data confirm AFSI and AFB as risk factors for ICC in eight developing countries, but any independent effects of these two events could not be distinguished.

Abstract
The authors carried out a hospital-based prospective study to evaluate the role of behavioral and clinical risk factors, occurring before and after diagnosis, on the prognosis of 146 patients with newly diagnosed oral cancer using Cox models. High weekly intake of vegetables before and after diagnosis were both associated with lower recurrence rates, longer overall survival and longer oral cancer survival. Diagnostic delay was associated with an increased risk of recurrence and oral cancer mortality. Patients presenting with pharyngeal pain or a mucosal lesion had a longer oral cancer survival than patients presenting with other symptoms. Quitting tobacco and alcohol consumption before and after diagnosis were both associated with a lower recurrence and/or better survival, but the effects were not statistically significant. This study suggests that high consumption of vegetables before and after diagnosis of oral cancer may reduce the risk of recurrence, overall mortality and cancer mortality in oral cancer patients.

Abstract
OBJECTIVES To determine seroprevalence and determinants of herpes simplex virus 2 (HSV-2) seropositivity, in a random sample of a population based cohort of 10 049 women of Guanacaste, Costa Rica, using a highly sensitive and specific serological assay. METHODS Seroprevalence was determined by a type specific HSV-2 ELISA assay in an age stratified random sample of 1100 women. Univariate and multivariate logistic regression was used to calculate odds ratios and 95% confidence intervals for risk factors of seropositivity. RESULTS Overall age adjusted HSV-2 seroprevalence was 38.5% (95% CI, 37.5 to 39.5), and it was strongly associated with increasing age (p(Trend<0.0001)), both among monogamous women and women with multiple sexual partners. A greater number of lifetime sexual partners increased the risk of seropositivity, with a 28.2% (95% CI, 24.4 to 32.2) seroprevalence among monogamous women and 75% (95% CI, 65.6 to 83.0) seroprevalence for those with four or more partners (OR = 7.6 95% CI, 4.7 to 12.4 p(Trend<0.0001)). Barrier contraceptive use was negatively associated with HSV-2 seropositivity (OR 0.54, 95% CI, 0.31 to 0.94). Women with antibodies against HPV 16, 18, or 31 were 1.6 times more likely to be HSV-2 seropositive (OR 1.6, 95% CI, 1.2 to 2.1). CONCLUSIONS HSV-2 infection is highly endemic in Guanacaste, even among lifetime monogamous women, suggesting a role of male behaviour in the transmission of the infection. Until vaccination against HSV-2 is available, education to prevent high risk sexual behaviour and the use of condoms appear as preventive measures against HSV-2.

Low BMIs at diagnosis and 2 years before diagnosis were associated with significantly elevated odds ratios (OR for BMI < or =22 vs >26 kg m(-2); 3.64; 95% confidence interval, CI: 2.27-5.82 and 3.31; 95% CI: 2.04-5.39, respectively). The association with low BMI, however, tended to be weaker and nonsignificant among never smokers and never drinkers.

Abstract
In the time period January 1998-December 2000, a case-control study on squamous cell cancer of the oesophagus was conducted in Montevideo, Uruguay. The main objective of the study was to estimate the odds ratios (ORs) associated with main food groups. For this purpose, 166 patients afflicted with squamous cell oesophageal cancer and 664 hospitalised controls were frequency matched on age and sex. Both series of patients were administered with a structured questionnaire. Aside from queries related with tobacco smoking, alcohol drinking and maté drinking, patients were interviewed with a food-frequency questionnaire (FFQ) on 64 items, representative of the usual Uruguayan diet. Red meat, salted meat and boiled meat displayed strong direct associations (OR for red meat 2.4, 95% CI 1.4-4.2). On the other hand, fish and total white meat showed moderate protective effect (OR for total white meat 0.5, 95% CI 0.3-0.9). Total fruit intake displayed a strong inverse association (OR 0.2, 95% CI 0.1-0.4), whereas total vegetable consumption presented a weak inverse association (OR for total vegetable intake 0.7, 95% CI 0.4-1.2). These results suggest that vegetables, mainly cooked vegetables, are rich in thermolabile protective substances. On the other hand, boiled (stewed) meat, which is ingested at high temperature could be, like maté, a risk factor for squamous cell cancer of the oesophagus.

Abstract
Cancer of the oral cavity and oropharynx is a major public health problem in Spain. Tobacco and alcohol have been identified as the two major risk factors for oral cancer in most western populations. Other risk factors include diets low in fruits and vegetables, but the impact of dietary habits on the risk of these cancers has never been assessed in Spain. The objective of this study was to elucidate the role of dietary habits in oral and oropharyngeal cancer, a multicentric case-control study was conducted in three areas of Spain (Barcelona, Granada and Sevilla) between 1996 and 1999. Cases were 375 patients (71 women), with incident, histologically confirmed cancer of the oral cavity or oropharynx, and controls were 375 subjects (71 women) admitted to hospitals for conditions unrelated to smoking or alcohol drinking. Data were analysed using multivariate logistic regression procedures. After allowance for education, tobacco and alcohol use, a significant inverse association with the risk of oral and oropharyngeal cancer was found for total consumption of total green vegetables (OR 0.54, 95% CI = 0.34-0.87) and total fruit (OR 0.52, 95% CI = 0.34-0.79) with significant trends in risk. We found that the protective effect of each of these food items was consistently larger among current smokers and among heavy alcohol drinkers, following a multiplicative effect model. In conclusion, this study provides further support to the beneficial effect of high intake of vegetables and fruits on the risk of developing cancers of the oral cavity and oropharynx in Spain, particularly among current smokers and heavy alcohol drinkers.

Abstract
Four-hundred-forty-five husbands of women with invasive cervical carcinoma, 165 of women with in situ cervical cancer, and 717 of control women (age range 19-82 years) were interviewed and a sample of exfoliated cells from the penis obtained in seven case-control studies conducted by the International Agency for Research on Cancer. The characteristics of human papillomavirus-positive and human papillomavirus-negative husbands were compared using odds ratios and 95% confidence intervals. Thirteen per cent of the husbands of control women, 18% of the husbands of women with invasive cervical carcinoma, and 21% of the husbands of in situ cervical carcinoma women were positive for penile human papillomavirus DNA. Human papillomavirus 16 was detected in 45 husbands, human papillomavirus 18, 31 or 33 in 19, and human papillomavirus 6/11 in 6, but the majority of human papillomavirus infection (158) was with other or unspecified human papillomavirus types. The same human papillomavirus type was seldom identified in both husband and wife. The strongest variation in penile human papillomavirus infection was by country, with percentages among the husbands of control women ranging between 3% in Spain and 39% in Brazil. Having had over 50 lifetime sexual partners, compared with only one, was associated with an odds ratio of 2.3.

Abstract
We studied the genotype distribution of cervical human papillomavirus (HPV) infections in an age-stratified sample of 262 women in Mozambique using the PGMYO9-PGMY11 primer system in a reverse line-blot strip-based assay with high sensitivity in type-specific amplification. Despite the low precision of the estimates, we found that HPV-16 was not the dominant type. Instead, HPV 35 was the most commonly identified genotype among HPV-positive women (16/96 [17%]) and women with cervical neoplasia (7/23 [30%]). Certain genotypes might have been under-detected in previous studies, and type-specific HPV distributions might vary across populations. Therefore, the estimated proportion of cervical neoplasia that could be prevented by an HPV-16-based vaccine could be lower than expected.

Abstract
This paper focuses on the health intervention developed in a camp of Albanian-Kosovar refugees, displaced as a consequence of the Balcans war in Kosova. Between May and June 1999, the camp of Kavajë in Albania, received 1,700 refugees, with an average age of 24 years old. During this period, 1904 cases were registered at the primary health care centre settled in the camp. The most frequent causes of consultation were respiratory infections (22%), external causes (21%), skin infections and intestinal diseases (12%). A part of the psychological damage, the population attended didn't present with relevant health problems. Most of the visits to the doctor, related to the difficulties suffered on their way to the camp and to the conditions they were living on.

Abstract
OBJECTIVES To explore the effectiveness of alcohol drinking and tobacco smoking cessation in reducing esophageal cancer risk, taking into account the key characteristics of each habit and the simultaneous exposure to both habits. METHODS Data from a series of five hospital-based case-control studies of incident squamous-cell carcinoma of the esophagus conducted by the International Agency for Research on Cancer (IARC, Lyon, France) in high-risk areas in South America were combined and analyzed by multivariate logistic regression procedures. A total of 2063 men (655 case patients and 1408 control subjects) were included in the pooled analysis. RESULTS For either habit, the risk of esophageal cancer decreased rapidly, strongly and significantly with longer periods of abstention. The risk reduction was statistically significant regardless of the intensity and duration of each habit and the type of tobacco or alcoholic drink consumed. For subjects exposed to both risk factors, the protective effect of quitting both habits appeared to be synergistic, reaching, after only five to nine years of simultaneous cessation of both exposures, a 70% risk reduction, a reduction that clearly overlapped with the risk intervals of both never-smokers and never-drinkers. The risk benefit of merely quitting alcohol drinking was delayed (>10 years of cessation) unless it was also accompanied by a few years of smoking cessation. CONCLUSIONS Our findings solidly demonstrate for the first time the effectiveness of smoking and drinking cessation in reducing esophageal cancer risk. For the large proportion of subjects in the general population exposed to both risk factors, our results further emphasize the importance of smoking cessation to effectively reduce cancer risk.

Abstract
To estimate the effects of consuming hot beverages, including mate (an infusion of the herb Ilex paraguayensis), tea, coffee and coffee with milk, and other food items on esophageal cancer risk, we analyzed data from 830 cases and 1,779 controls participating in a series of 5 hospital-based case-control studies of squamous-cell carcinoma of the esophagus conducted in high-risk areas of South America. After adjusting for the strong effects of tobacco and alcohol consumption, both heavy mate drinking (>1 l/day) and self-reported very hot mate drinking were significantly associated with esophageal cancer risk in men and women. The magnitude and strength of the association for mate amount and, to a lesser extent, mate temperature were higher for women than men. The joint effects of mate amount and mate temperature were more than multiplicative, following a statistically significant synergistic interaction (p = 0.02) which was particularly evident among heavy drinkers (>1.50 l/day) of very hot mate (odds ratio = 4.14, 95% confidence interval: 2.24-7.67) compared to light drinkers (<0.50 l/day) of cold/warm/hot mate. Consumption of other very hot beverages, such as tea and coffee with milk but not coffee alone, was also significantly associated with an increased risk, in the 2- to 4-fold range. Statistically significant protective associations were identified for high consumption of vegetables, fruits, cereals and tea. In contrast, frequent consumption of meat, animal fats and salt was associated with a moderately increased risk. This pooled analysis adds evidence for a carcinogenic effect of chronic thermal injury in the esophagus induced by the consumption of very hot drinks, including mate. Our study further confirms the protective effect of a dietary pattern characterized by daily consumption of fruits and vegetables and low consumption of meat and animal fats.

Abstract
We have examined whether the extended life span of cells induced by Bcl-2 in T(1) ductal breast carcinomas might favor the acquisition and accumulation of genetic alterations that induce lymph node metastases. We analyzed the expression of c-Myc, c-erbB-2 and epidermal growth factor receptor by immuno-histochemistry in a group of 142 T(1) (<2 cm) ductal breast carcinomas embedded in paraffin, previously studied for p53 mutation and Bcl-2 over-expression. We also measured the apoptotic status and estimated the excess risk (pOR) for lymph node metastasis according to the number of accumulated oncogene alterations and Bcl-2 and p53 expression. The linear relationship between number of oncogene alterations and presence of lymph node metastasis was statistically significant in Bcl-2-positive tumors (trend test, p = 0.03), p53-mutated tumors (trend test, p = 0.08) and tumors with loss of apoptosis (trend test, p = 0.08). Very large associations (pOR > 12) between the number of oncogene alterations and lymph node metastasis were observed among Bcl-2-positive tumors that showed increased loss of apoptosis (trend test, p = 0.03). Furthermore, in p53-negative tumors, a strong linear association was found between the number of oncogene alterations and risk of lymph node metastasis among Bcl-2-positive tumors (trend test, p = 0.03). In human T(1) ductal breast carcinoma, over-expression of Bcl-2 along with loss of apoptosis might render breast cancer cells susceptible to the acquisition of additional genetic lesions related to disease progression among p53-negative tumors. Thus, in breast cancer, there are at least 2 pathways to progression: Bcl-2- and p53-dependent mechanisms.

Abstract
The purpose of this study was to assess the prognostic effect of the expression of E-cadherin, beta-catenin and CD44 adhesion molecules in bladder carcinoma. 22 superficial and 18 invasive bladder tumour samples were studied by immunohistochemistry. The median follow-up was 24 months (range: 1-50 months). Loss of E-cadherin and beta-catenin immunoreactivity was found in 14 (35%) and 17 (43%) tumours, respectively, and was significantly associated with invasiveness, high grade and p53 overexpression. There was no correlation between CD44 variant expression and clinicopathological findings. Loss of E-cadherin expression was an independent predictor of poor survival in a multivariate analysis, when assessed with age, grade, stage and p53 status (hazards ratio adjusted (HRa)=4.45 [95% confidence interval (CI), 1.06-18.63]). This effect was particularly augmented in patients with invasive bladder cancer. When expression of E-cadherin and beta-catenin were evaluated simultaneously, loss of immunoreactivity of both proteins was a strong predictor of poor survival (HRa=13.06 [95% CI, 0.95-178.55]). The same pattern was found when progression-free survival in relation to these variables was assessed. In conclusion, assessment of E-cadherin and beta-catenin immunoreactivity may be a useful prognostic marker in bladder cancer complementary to established prognostic factors.

Abstract
The treatment of squamous cell carcinoma of the mouth and oropharynx continues to change. In this primary report, we compared the results obtained by combined surgery and radiation therapy, or either modality alone. Other methods such as brachytherapy, or hyperfractionated radiotherapy, were not included in our protocols. A statistical analysis of the 3- and 5-year survival rates in relation to location and size of the primary tumour, stage at initial presentation, treatment modality and recurrence, was carried out in 88 patients with squamous cell carcinoma of the oral cavity or oropharynx. The overall survival rate was 73.8% at 3 years and 66.3% at 5 years. Size of tumour and stage at presentation were significant when P value was adjusted by site. Survival was significantly associated with type of treatment (combined approach obtained superior results), location of primary tumour, and recurrence. The type of neck dissection did not show any effect. Therapeutic modality used, stage, and location of primary tumour significantly influenced survival. A more selective combined initial treatment according to site and stage (distribution) is recommended.

Abstract
Herein we describe our experience with 75 consecutive autologous BM transplants for patients with high-risk ALL, with special attention to the clinical impact of BM purging. Fifty-two patients received purged BM using monoclonal antibody (MoAb) cocktails and complement, and 23 patients received untreated BM. The distribution of prognostic factors was similar in both groups. Hemopoietic reconstitution was adequate and did not differ in the two groups. Transplant-related mortality was 9.6% and 13% in 'purged' and 'unpurged' groups. Median follow up was 11 months (2-71) and overall actuarial probability of disease-free survival (DFS) at 5 years was 40% (53% relapse probability). We found a beneficial effect of purging in patients over 15 years of age and in patients needing more than 1 month to reach CR1. Patients in CR1 receiving purged marrow had a longer DFS and a lower relapse probability (52% vs 12%, P = 0.02 and 35% vs 86%, P = 0.005, respectively) which were related to the efficacy of the purging procedure (more or less than one log of depletion). In further CR, no advantage of purging has been found. Our data strongly suggest the clinical relevance of BM purging in autologous BMT in high-risk ALL patients and support the need for prospective randomized studies.

Abstract
The aim of the present study was to determine the efficacy of an antibiotic-lock technique in preventing endoluminal catheter-related infection with gram-positive bacteria in neutropenic patients with hematologic malignancies. Patients with nontunneled, multilumen central venous catheters were assigned in a randomized, double-blinded manner to receive either 10 U of heparin per ml (57 patients) or 10 U of heparin per ml and 25 microg of vancomycin per ml (60 patients), which were instilled in the catheter lumen and which were allowed to dwell in the catheter lumen for 1 h every 2 days. Insertion-site and hub swabs were taken twice weekly. The primary and secondary end points of the trial were significant colonization of the catheter hub and catheter-related bacteremia, respectively. Significant colonization of the catheter hub occurred in nine (15.8%) patients receiving heparin (seven patients were colonized with Staphylococcus epidermidis, one patient was colonized with Staphylococcus capitis, and one patient was colonized with Corynebacterium sp.), whereas the catheter hubs of none of the patients receiving heparin and vancomycin were colonized (P = 0.001). Catheter-related bacteremia developed in four (7%) patients receiving heparin (three patients had S. epidermidis bacteremia and one patient had S. capitis bacteremia), whereas none of the patients in the heparin and vancomycin group had catheter-related bacteremia (P = 0.05). The times to catheter hub colonization and to catheter-related bacteremia by the Kaplan-Meier method were longer in patients receiving heparin and vancomycin than in patients receiving heparin alone (P = 0.004 and P = 0.06, respectively). Our study shows that a solution containing heparin and vancomycin administered by using an antibiotic-lock technique effectively prevents catheter hub colonization with gram-positive bacteria and subsequent bacteremia during chemotherapy-induced neutropenia in patients with hematologic malignancy.

Abstract
To estimate the independent and joint effects of tobacco smoking and alcohol drinking, we analyzed data from a series of 5 hospital-based case-control studies of squamous-cell carcinoma of the esophagus conducted in high-risk areas in South America. A total of 830 case subjects and 1779 control subjects were included in the pooled analysis. All exposure characteristics of amount, duration, cessation and type of alcohol and tobacco consumed were strongly related to esophageal-cancer risk in both sexes. Women had the same exposure profile as men, but the magnitudes of the associations were lower than were those among men. Black-tobacco smoking was associated with a 2-fold increased risk as compared with the smoking of blond or mixed tobacco. Quitting either of the 2 habits significantly reduced esophageal-cancer risk. Alcohol and tobacco alone were strongly related to the risk of esophageal cancer, even in the absence of the other exposure. A history of simultaneous exposure to cigarette smoking and alcohol drinking had a strong multiplicative effect on risk. Concomitant exposure to heavy alcohol drinking and black-tobacco smoking identified the group with the highest risk for developing esophageal cancer (odds ratio = 107). A synergistic interaction was found between the 2 habits, particularly in women and in moderately exposed men. Moderate cigarette smoking without drinking and moderate alcohol drinking without smoking had a negligible effect on esophageal-cancer risk. However, simultaneous exposure to the same moderate amounts increased the risk 12- to 19-fold in men and in women respectively. The overall public-health implications of these findings are obvious for a tumor that depends on preventive strategies for its control.

Abstract
Expression of the death-related proteins (DRPs) Bcl-2, Bax, Bcl-x and Bak that regulate cell survival and death was examined using immuno-histochemical methods in a group of 142 T1 (<2 cm) ductal breast carcinomas. Immunostaining results were correlated with loss of apoptosis and clinicopathological parameters such as histological grade (HG) and lymph node involvement. Expression of anti-apoptotic proteins Bcl-2 and Bcl-x was found in 57.0% and 62.75% of tumors, respectively. Bcl-2 expression, but not Bcl-x expression, was related to loss of apoptosis. Expression of the apoptotic proteins Bax and Bak was present in 58% of Bcl-2-negative tumors and associated significantly with an increase in apoptosis. Expression of these DRPs was associated significantly with the HG of the tumors: Bcl-2 and Bak expression was predominant in HG I/II tumors, whereas expression of Bcl-xL and Bax was commonly observed in HG III tumors, as occurs for p53 over-expression. Our results suggest that the loss or gain of apoptosis is regulated tightly in T1 breast carcinomas through the expression of different effectors along with tumor cell differentiation.

Abstract
In Northern Africa, cervical cancer is the second most common cancer among women. The diagnosis is usually made in advanced stages, and mortality is high, yet few studies have investigated the role of human papillomavirus (HPV) and other risk factors in the etiology of cervical cancer. A hospital-based case-control study was completed at the Institut National d'Oncologie (INO) in Rabat, Morocco. The study included 214 cases of invasive cervical cancer and 203 controls. A structured questionnaire was used to investigate known and suspected risk factors for cervical cancer. A GP 5+/6+ polymerase chain reaction system was used to detect the presence of HPV DNA and HPV type distribution. Probes for 30 HPV types were used in one research laboratory. HPV DNA was the central risk factor and accounted for the large majority of the cases. The adjusted odds ratio (ORa) for any HPV was 61.6 (95% CI, 29.2-130) and the corresponding HPV attributable fraction (AF) was 92%. Among cases of cervical cancer, HPV 16 was the most common type (67.7%) followed by HPV 18. The HPV type-specific prevalence was similar for squamous cell carcinomas and adenocarcinomas. In multivariate adjusted or HPV-stratified analyses, in addition to the strong effect of HPV, other risk factors identified were sexual intercourse with multiple partners before the age of 20 and low socio-economic status. Use of oral contraceptives for 5 or more years and high parity were also found to be related to cervical cancer. Screening was rare in this population but offered substantial protection against cervical cancer. In Morocco, cervical cancer is a late sequel of a viral infection with certain HPV types. Developing screening programs for preneoplastic cervical lesions is a public health priority. When available, HPV vaccination would offer a relevant alternative for preventing cervical cancer.

Abstract
To investigate the role of men in cervical cancer, 816 husbands of women enrolled in four case-control studies of cervical neoplasia in populations at high (Colombia) and low (Spain) risk for cervical cancer were interviewed. Exfoliated cells from the penis were obtained and analyzed by polymerase chain reaction for the presence of human papillomavirus (HPV) DNA. Penile HPV DNA prevalences were higher in husbands of women with cervical neoplasia than in husbands of controls. Husbands of controls in Colombia had a 5-fold higher penile HPV DNA prevalence than the corresponding husbands in Spain. Strong dose-response relationships were found between penile HPV DNA prevalence and all sexual behavior-related variables in Spain but not in Colombia. Sexual promiscuity is the most important risk factor for penile HPV infections. Differences in HPV DNA prevalence in the male populations of Spain and Colombia are consistent with their 8-fold difference in cervical cancer incidences.

Abstract
PURPOSE To assess whether human papillomavirus (HPV) DNA detection in cervical cancer specimens, or antibodies to selected HPV 16 peptides are predictors of tumor recurrence and long-term survival in patients with squamous cell invasive cervical cancer. SUBJECTS AND METHODS Four hundred seventy-one cases included in two population-based case-control studies underwent follow-up evaluation. The survival and cause of death were ascertained for 410 cases (87%), with a median follow-up time of 4.6 years after diagnosis. HPV DNA was assessed using an L1 polymerase chain reaction (PCR)-based system and Southern hybridization (SH) on scraped cytologic specimens or biopsies. HPV 16 antibodies to E2, L2, and E7 peptides were detected with enzyme-linked immunosorbent assay (ELISA). RESULTS Clinical stage was the only independent prognostic factor for recurrence or survival. Although seropositivity to HPV 16 E7/3 peptide predicted a twofold excess risk of mortality (adjusted hazards ratio [HRa] = 2.0; 95% confidence interval [CI], 1.2 to 3.3), the association was restricted to stage I (HRa = 6.6; 95% CI, 1.2 to 37.6) and II (HRa = 5.9; 95% CI, 2.1 to 16.5) patients. The presence of HPV DNA (HRa = 0.9; 95% CI, 0.5 to 1.5), different estimates of the HPV viral load and the HPV type identified were not predictors of tumor recurrence or survival. CONCLUSION The presence of antibodies to HPV 16 E7 proteins is of prognostic value in early-stage cervical cancer. Our results provide strong evidence that detection and typing of HPV DNA in cervical cells or tissues is not a prognostic factor for recurrence or survival.

Abstract
The B-cell chronic lymphocytic leukemia (B-CLL) is a heterogeneous disease, its clinical and biological behavior possibly being influenced by surface molecules expressed in B-lymphocytes. These molecules mediate cell adhesion, mobility and homing. Expression of surface adhesion molecules of the integrin family (CD11a/CD18 or LFA-1, CD11c/CD18), of the immunoglobulin-related family (CD54), of the selectin family (CD62L or LAM-1) and the lymphocyte homing receptor (CD44) were analyzed in peripheral cells from 113 B-CLL patients. The association with three prognosis-related parameters (Rai stage, bone marrow pattern and doubling time) was determined. The study included only patients with B-CLL lymphocytes of typical morphology, which always expressed CD5 and CD23. Low expression of integrins, particularly CD18, was associated with advanced disease (Rai stages III-IV) and diffuse bone marrow pattern, even after adjusting for other prognosis-related variables. Expression of CD54 was associated independently with rapid doubling time (less than 12 months). The association persisted after adjusting for stage and bone marrow pattern; CD44 was expressed in all patients. No correlations were found between expression of CD62L and the prognostic variables analyzed. In conclusion, CD54 expression and low CD18 expression are both significantly associated with poor prognostic features.
