Sentinel Pap smears in 261 invasive cervical cancer patients in Italy

Although cervical cytology screening has dramatically reduced its incidence, cervical cancer still occurs. The clinical history of 261 cervical cancer patients referred to the European Institute of Oncology between 1996 and 2006 was analysed in depth to better understand the difficulties in the diagnosis and prevention of this neoplasia in Italy. Data concerning anagraphical characteristics, tumour type and stage, Pap smear history, colposcopic and histologic data, treatment outcome were reviewed. Patients who had taken Pap smear in the 3-year time span preceding diagnosis were 199 and 55 (27.7%) of these smears were negative. A negative Pap smear was observed in 62.5% of the women with a cancer at stage IV or III. One hundred and seventy-two patients were symptomatic at diagnosis: 43 (25%) had a negative Pap smear in the 3 years preceding diagnosis while 54 (31.4%) had never done a Pap smear or had one taken more than 3 years before. Eighty-nine women were asymptomatic at the time of diagnosis; 13 patients (14.6%) had a negative Pap smear while 8 had no smear taken in the 3 years preceding diagnosis or no smear at all. The present retrospective investigation indicates that the screening system still has some critical points. Although multiple techniques and approaches have been proposed to improve the general performance of the system, prophylactic vaccination may dramatically limit the failures in an easier, and possibly more cost-effective way. We also stress that history taking and clinical examination are important tools to diagnose cervical cancers. However a clinical diagnosis requires experience, which, with the advent of more efficient screening system and prophylactic vaccination, many of the newer practising gynaecologists might lack.

Pap smear rates among Haitian immigrant women in eastern Massachusetts

OBJECTIVE: Given limited prior evidence of high rates of cervical cancer in Haitian immigrant women in the U.S., this study was designed to examine self-reported Pap smear screening rates for Haitian immigrant women and compare them to rates for women of other ethnicities. METHODS: Multi-ethnic women at least 40 years of age living in neighborhoods with large Haitian immigrant populations in eastern Massachusetts were surveyed in 2000-2002. Multivariate logistic regression analyses were used to examine the effect of demographic and health care characteristics on Pap smear rates. RESULTS: Overall, 81% (95% confidence interval 79%, 84%) of women in the study sample reported having had a Pap smear within three years. In unadjusted analyses, Pap smear rates differed by ethnicity (p=0.003), with women identified as Haitian having a lower crude Pap smear rate (78%) than women identified as African American (87%), English-speaking Caribbean (88%), or Latina (92%). Women identified as Haitian had a higher rate than women identified as non-Hispanic white (74%). Adjustment for differences in demographic factors known to predict Pap smear acquisition (age, marital status, education level, and household income) only partially accounted for the observed difference in Pap smear rates. However, adjustment for these variables as well as those related to health care access (single site for primary care, health insurance status, and physician gender) eliminated the ethnic difference in Pap smear rates. CONCLUSIONS: The lower crude Pap smear rate for Haitian immigrants relative to other women of color was in part due to differences in (1) utilization of a single source for primary care, (2) health insurance, and (3) care provided by female physicians. Public health programs, such as the cancer prevention programs currently utilized in eastern Massachusetts, may influence these factors. Thus, the relatively high Pap rate among women in this study may reflect the success of these programs. Public health and elected officials will need to consider closely how implementing or withdrawing these programs may impact immigrant and minority communities.     

The efficacy of liquid-based cervical cytology using direct-to-vial sample collection

BACKGROUND: Previous studies of liquid-based cervical cytology (LBCC) have used a split sample collection technique that creates a potential negative bias for its evaluation. Thus, the full diagnostic potential of LBCC has not been established. The purpose of our study was to determine rates of specimen adequacy and cervical cytologic and histologically confirmed diagnoses obtained with a liquid-based Papanicolaou (Pap) test using a direct-to-vial sample collection technique and compare these results with those obtained using the conventional Pap test (CPT). METHODS: A total of 1004 nonpregnant women aged 18 years or older with an intact cervix had Pap tests collected with an Ayre spatula and cytobrush, and the sample was placed in a preservative solution. The specimens were processed as thin layer Pap tests according to the manufacturer's specifications. Another group of 2110 women with a similar patient profile had a CPT collected immediately preceding the initiation of the trial. The subjects in each group consisted of an equal percentage of women presenting for a routine Pap test or a colposcopy examination. We compared the distributions of diagnostic categories between the groups using a chi-square test. RESULTS: A significantly greater percentage of satisfactory Pap tests were obtained using LBCC (84.0%) compared with the CPT (60.5%, P < .001). Fewer satisfactory but limited by (SBLB, 14.8%) and unsatisfactory (1.2%) Pap tests were reported using LBCC compared with the CPT (35.7% and 3.8%, respectively, chi2 = 170.7, P < .001). A significantly greater percentage of low-grade squamous intraepithelial lesion (LSIL) and high-grade squamous intraepithelial lesion (HSIL) Pap test results were reported using LBCC (7.4% and 3.7%, respectively) compared with the CPT (1.7% and 1.7%, respectively, chi2 = 74.4, P < .001). The predictive value of a positive LBCC test (93.9%) was similar to that for a positive CPT (87.8%) when compared with histology results. CONCLUSIONS: Compared with the CPT, LBCC detected a significantly greater percentage of satisfactory Pap tests and significantly reduced the number of unsatisfactory and SBLB tests. Four times the percentage of LSIL and twice the percentage of HSIL Pap test results were obtained using LBCC compared with the CPT. These findings demonstrate that LBCC significantly improves the adequacy of Pap tests and may increase the rate of detection of cervical neoplasia compared with the CPT.
