RESUMEN
OBJECTIVE: To investigate prognostic factors in patients with recurrent cervical cancer after treatment of early-stage disease in order to identify high-risk patients who might benefit from alternative treatment strategies. STUDY DESIGN: The authors retrospectively analyzed clinical and pathology data from 130 recurrent cervical cancer patients after surgical treatment for early-stage disease. Patients were compared with a recurrence-free control group matched for age, FIGO Stage, and adjuvant treatment. Univariate and multivariate Cox regression analyses were performed to determine prognostic factors for recurrence and survival. RESULTS: Of 889 patients, 130 (14.6%) developed recurrent disease after primary treatment for early-stage cervical cancer. Local or loco-regional metastasis was observed in 45%, distant metastasis in 31%, and combined pelvic and distant metastasis in 24%. Median survival after recurrence was 12 months (range 1-107 months). Median five-year survival was 96% in the control group and 29% in the recurrence group. Tumor size ≥ 40 mm and lymph node metastasis were independent unfavorable prognostic factors for overall survival (OS) and disease-free survival (DFS). The number of positive lymph nodes (≥ one) and bilateral occurrence of pelvic lymph node metastasis were associated with adverse clinical outcome. CONCLUSIONS: Tumor size ≥ 40 mm and lymph node metastasis were independent unfavorable prognostic factors in surgically treated, early-stage cervical cancer patients. The combination of these factors was particularly associated with recurrence. Future trials should focus on the role of alternative adjuvant treatment strategies in patients at high risk of recurrent disease (e.g., by chemotherapy, immunotherapy or combinations thereof).

This study aims to confirm the feasibility of near-infrared (NIR) fluorescence imaging for sentinel lymph node (SLN) biopsy in vulvar cancer and to compare the tracer indocyanine green (ICG) bound to human serum albumin (HSA) versus ICG alone. Women received 99mTc-nanocolloid and patent blue for SLN detection. Subsequently, women randomly received ICG:HSA or ICG alone. In 24 women, 35 SLNs were intraoperatively detected. All SLNs detected were radioactive and NIR fluorescent and 27 (77%) were blue. No significant difference was found between ICG:HSA and ICG alone. This trial confirms the feasibility of NIR fluorescence imaging for SLN mapping in vulvar cancer.

OBJECTIVE: to investigate whether morphologic characteristics determined by magnetic resonance imaging (MRI) can discriminate between bulky cervical tumours with a favourable or worse prognosis. MATERIALS AND METHODS: MRI examinations were performed in 24 patients with cervical cancer Stage >or= 1B2. The ratio between tumour width and length (barrel index: BI) and the presence of intrauterine fluid retention were related to survival in a multivariate regression analysis. RESULTS: BI and intracavital fluid were predictors of survival, independent from tumour diameter and other known important factors for survival. A cut-off value of 1.40 for the BI proved to be the best prognostic factor with respect to recurrence and death: the hazard ratios of BI > 1.40 as compared to BI Asunto(s)

RESUMEN
BACKGROUND: Previously, we have shown that low IL-12p40 mRNA expression by cervical cancer cells is associated with a poor survival of cervical cancer patients. As IL-12p40 is both a subcomponent of interleukin (IL)-12 and IL-23, the aim of this study was to elucidate the role of IL-12p40 in cervical cancer. METHODS: We have measured the expression of IL-23p19 mRNA, IL-12p35 mRNA and IL-12p40 mRNA using mRNA in situ hybridisation. The IL-1 and IL-6 were measured by immunohistochemistry. RESULTS: As IL-23 is a component of the IL-17/IL-23 pathway, a pathway induced by IL-1 and IL-6 in humans, we have studied IL-1 and IL-6 expression. Only a high number of stromal IL-6-positive cells was shown to associate with poor disease-specific survival. The worst disease-specific survival was associated with a subgroup of patients that displayed a high number of IL-6-positive cells and low IL-12p40 expression (P<0.001). Both a high number of IL-6-positive cells and a high number of IL-6-positive cells, plus low IL-12p40 expression were shown to be clinicopathological parameters independent of lymph node metastasis, parametrial involvement and Sedlis score (P=0.009 and P=0.007, respectively). CONCLUSION: Our results with IL-6 and IL-12p40 are in accordance with the hypothesis that the IL-17/IL-23 pathway has a suppressive role in cervical cancer.

BACKGROUND: The CXC chemokine receptor (CXCR)7 is involved in tumour development and metastases formation. The aim of the present study was to determine protein expression of CXCR7, its putative co-receptors epidermal growth factor receptor (EGFR) and CXCR4, its predominant ligand CXCL12, their co-dependency and their association with survival in cervical cancer patients. METHODS: CXC chemokine receptor 7, EGFR, CXCR4 and CXCL12 expression were determined immunohistochemically in 103 paraffin-embedded, cervical cancers. Subsequently, associations with patient characteristics were assessed and survival analyses were performed. RESULTS: CXC chemokine receptor 7 was expressed by 43% of tumour specimens, in a large majority of cases together with either EGFR or CXCR4 (double positive), or both (triple positive). The CXCR7 expression was associated with tumour size (P=0.013), lymph node metastasis (P=0.001) and EGFR expression (P=0.009). CXC chemokine receptor 7 was independently associated with disease-free survival (hazard ratio (HR)=4.3, 95% confidence intervals (CI) 1.7-11.0, P=0.002), and strongly associated with disease-specific survival (HR=3.9, 95% CI 1.5-10.2, P=0.005). CONCLUSION: CXC chemokine receptor 7 expression predicts poor disease-free and disease-specific survival in cervical cancer patients, and might be a promising new therapeutic marker. In a large majority of cases, CXCR7 is co-expressed with CXCR4 and/or EGFR, supporting the hypothesis that these receptors assist in CXCR7 signal transduction.

BACKGROUND: We performed a cross-sectional study in Indonesia to evaluate the performance of a single-visit approach of cervical cancer screening, using visual inspection with acetic acid (VIA), histology and cryotherapy in low-resource settings. METHODS: Women having limited access to health-care facilities were screened by trained doctors using VIA. If the test was positive, biopsies were taken and when eligible, women were directly treated with cryotherapy. Follow-up was performed with VIA and cytology after 6 months. When cervical cancer was suspected or diagnosed, women were referred. The positivity rate, positive predictive value (PPV) and approximate specificity of the VIA test were calculated. The detection rate for cervical lesions was given. RESULTS: Screening results were completed in 22 040 women, of whom 92.7% had never been screened. Visual inspection with acetic acid was positive in 4.4%. The PPV of VIA to detect CIN I or greater and CIN II or greater was 58.7% and 29.7%, respectively. The approximate specificity was 98.1%, and the detection rate for CIN I or greater was 2.6%. CONCLUSION: The single-visit approach cervical cancer screening performed well, showing See and Treat is a promising way to reduce cervical cancer in Indonesia.

BACKGROUND: Incomplete surgical staging of patients with early-stage epithelial ovarian cancer (EOC) has been reported in up to 98% of cases, when based on the International Federation of Obstetrics and Gynecology (FIGO) staging procedure. The aim of the present retrospective study was to clarify the reasons for incomplete staging. METHODS: The PRISMA (Prevention Recovery Information System for Monitoring and Analysis) technique was used to evaluate cases with FIGO I-IIa EOC based on incomplete staging from five gynecologic oncologic center hospitals in the Netherlands in the period 2010-2014. RESULTS: Fifty cases with an incomplete surgical staging of EOC according to national guidelines were included. The most common reasons for incomplete staging were insufficient random biopsies of the peritoneum (nâ¯=â¯34, 68%), and less than ten lymph nodes being resected and/or found at pathology (nâ¯=â¯16, 32%). The most mentioned reason for not performing biopsies was, besides forgetting to do so, believing that after careful inspection and palpation, taking biopsies is irrelevant and/or already are being taken while performing a hysterectomy (peritoneum of cul-de-sac, bladder). The value of contralateral pelvic lymph node dissection in case of a unilateral ovarian malignancy was also doubted, influencing the number of lymph nodes resected. CONCLUSIONS: The most important reasons for incomplete staging in EOC are, besides omitting elements by accident, questioning the importance of obligatory elements of the staging procedure. A structured list of staging steps during surgery and more evidence-based consensus concerning these obligatory elements might increase the number of complete staging procedures in EOC.
RESUMEN
OBJECTIVES: The aims of this study were: to determine the incidence of concurrent infections on a serovar level; to determine the incidence of multiple anatomical infected sites on a detection and genotyping level and analyse site-specific serovar distribution; to identify tissue tropism in urogenital versus rectal specimens. METHODS: Chlamydia trachomatis-infected patients in two populations were analysed: 75 visiting the outpatient department of obstetrics and gynaecology of the MC Haaglanden, and 358 visiting the outpatient sexually transmitted disease clinic, The Hague, The Netherlands. The PACE 2 assay (Gen-Probe) was used to detect C trachomatis from urethral, cervical, vaginal, oropharyngeal and anorectal swabs. C trachomatis genotyping was performed on all C trachomatis positive samples, using the CT-DT genotyping assay. RESULTS: Samples from 433 patients (256 female and 177 male) with confirmed C trachomatis infection were analysed. In 11 patients (2.6%), concurrent serovars in one anatomical sample site were present. In 62 (34.1%) female and four (9.3%) male patients, multiple sample site infections were found. A substantial percentage of women tested at the cervical/vaginal and rectal site were found to be positive at both sites (36.1%, 22/61). In men, D/Da and G/Ga serovars were more prevalent in rectal than urogenital specimens (p=0.0081 and p=0.0033, respectively), while serovar E was more prevalent in urogenital specimens (p=0.0012). CONCLUSIONS: The prevalence of multiple serovar infections is relatively low. Significant differences in serovar distribution are found in rectal specimens from men, with serovar G/Ga being the most prominent, suggesting tissue tropism.

BACKGROUND: An analysis was performed comparing survival of patients with clear cell carcinoma (CCC) to patients with serous adenocarcinoma (SAC) in early ovarian cancer. Furthermore, a literature search was done to clarify the clinical and histopathological features of clear cell tumors of the ovary. METHODS: Between November 1990 and March 2000, 448 patients with ovarian cancer International Federation of Gynecology and Obstetrics stages I to IIa were enrolled in the European Organisation for Research and Treatment of Cancer-Adjuvant Chemotherapy in Ovarian Neoplasm Trial, a randomized study comparing adjuvant platinum-based chemotherapy to observation after surgical treatment in patients with early ovarian cancer. RESULTS: Sixty-three patients (14.1%) with CCC were compared with 156 patients (34.8%) with serous tumors. A significant difference was found in the International Federation of Gynecology and Obstetrics stage Ic with capsule rupture, 28 (44.4%) of 63 patients with CCC and 29 (18.6%) of 156 patients with SAC (P < 0.001). Recurrences occurred in 25% of the patients, and this was similar in the CCC and SAC groups. No significant difference was found in overall survival between patients with CCC and patients with SAC in both treatment arms together. In the observation arm, the 5-year disease-free survival was 71% in the CCC group versus 61% in the SAC group, whereas in the chemotherapy arm, the 5-year disease-free survival was higher in the SAC group compared with the CCC group (78% vs 60%). Both differences were not statistically significant. CONCLUSIONS: The present study showed no worse prognosis in patients with CCC as compared with patients with serous carcinoma in early ovarian cancer.

The Piver classification of radical hysterectomy for the treatment of cervical cancer is outdated and misused. The Surgery Committee of the Gynecological Cancer Group of the European Organization for Research and Treatment of Cancer (EORTC) produced, approved, and adopted a revised classification. It is hoped that at least within the EORTC participating centers, a standardization of procedures is achieved. The clinical indications of the new classification are discussed.

To evaluate the possibility to give a prediction of the future (disease-free) survival, given the fact that a patient with a history of early-stage cervical cancer has been disease free for a specific period after treatment. Between January 1984 and April 2005, 615 patients with cervical cancer stages I-IIA underwent radical hysterectomy with or without adjuvant radiotherapy. The Kaplan-Meier method was used to detect statistical significance and multistate risk models to estimate the influence of covariates and to generate predicted survival curves by simulation. Simulations were done for patients with positive lymph nodes (n= 123), patients with negative lymph nodes (n= 492), and 4 hypothetical patients. The 5-year cancer-specific survival and disease-free survival of the entire group was 84% and 76%, respectively. The probability of death of the two lymph node groups and the four hypothetical patients was demonstrated in predicted cumulative probability plots. It is possible with multistate risk models to give a detailed prediction of the future (disease-free) survival, given the fact that a patient has been disease free for a specific period after treatment. This possibility is an important step forward to improve the quality of cancer care.

Radical hysterectomy with pelvic lymphadenectomy (RHL) for cervical cancer causes damage to the autonomic nerves, which are responsible for increased vaginal blood flow during sexual arousal. The aim of the study of which we now report preliminary data was to determine whether a nerve-sparing technique leads to an objectively less disturbed vaginal blood flow response during sexual stimulation. Photoplethysmographic assessment of vaginal pulse amplitude (VPA) during sexual stimulation by erotic films was performed. Subjective sexual arousal was assessed after each stimulus. Thirteen women after conventional RHL, 10 women after nerve-sparing RHL, and 14 healthy premenopausal women participated. Data were collected between January and August 2006. The main outcome measure was the logarithmically transformed mean VPA. To detect statistically significant differences in mean VPA levels between the three groups, a univariate analysis of variance was used. Mean VPA differed between the three groups (P= 0.014). The conventional group had a lower vaginal blood flow response than the control group (P= 0.016), which tended also to be lower than that of the nerve-sparing group (P= 0.097). These differences were critically dependent on baseline vaginal blood flow differences between the groups. The conventional group follows a vaginal blood flow pattern similar to postmenopausal women. Conventional RHL is associated with an overall disturbed vaginal blood flow response compared with healthy controls. Because it is not observed to the same extent after nerve-sparing RHL, it seems that the nerve-sparing technique leads to a better overall vaginal blood flow caused by less denervation of the vagina.

Drainage, following radical hysterectomy and pelvic lymph node dissection to prevent postoperative lymphocyst formation and surgical morbidity, is controversial. To study the clinical significance of drainage, 253 patients were registered and 234 patients were randomised into two arms. In one arm (n=117) postoperative drainage was performed, in the other arm (n=117) no drains were inserted. In both arms closure of the peritoneum of the operating field was omitted. The main exclusion criteria were blood loss of more than 3000 ml during surgery or persistent oozing at the end of the operation. Clinical and ultrasound or CT-scan evaluation was done at one and 12 months postoperatively. The median follow-up amounted to 13.3 months. No difference in the incidence of postoperative lymphocyst formation or postoperative complications was found between the two study arms. The late (12 months) incidence of symptomatic lymphocysts was 3.4% (drains: 5.9%; no drains: 0.9%). The difference showed a p-value of 0.06 in Fisher's Exact test. The operating time was related to the occurrence of postoperative lymphocyst formation. It was concluded that drains can be safely omitted following radical hysterectomy and pelvic node dissection without pelvic reperitonisation in patients without excessive bleeding during or oozing at the end of surgery.

AIMS: To determine if the number of removed lymph nodes in radical hysterectomy with lymphadenectomy (RHL) influences survival of patients with early stage cervical cancer and to analyze the relation of different factors like patient age, tumour size and infiltration depth with the number of nodes examined in node-negative early stage cervical cancer patients. METHODS: Of consecutive patients, who underwent RHL between January 1984 and April 2005, 331 had negative nodes (group A) without adjuvant therapy and 136 had positive nodes (group B). The Kaplan-Meier method and Cox regression model were used to detect statistical significance. Factors associated with excision of nodes were confirmed with linear regression models. RESULTS: The median number of removed nodes was 19 and 18 for group A and group B, respectively. There was no significant relationship between the number of removed nodes and the cancer specific survival (CSS) or disease free survival (DSF) for patients of group A (p=0.625 and p=0.877, respectively). The number of removed nodes in group B was not significantly associated with the CSS (p=0.084) but it was for the DSF (p=0.014). Factors like patient age, tumour size and infiltration depth were not associated with the number of nodes. CONCLUSIONS: No relation was found between the number of negative nodes examined after RHL for the treatment of early stage cervical cancer and CSS or DFS. However, a higher amount of removed lymph nodes leaded to a better DFS for patients with positive nodes. It is suggested that patients with positive nodes benefit from a complete pelvic lymphadenectomy and a sufficient yield of removed nodes.

BACKGROUND: This study was conducted to assess the accuracy and feasibility of diagnostic hysteroscopy in the evaluation of intrauterine abnormalities in women with abnormal uterine bleeding. SEARCH STRATEGY: Electronic databases were searched from 1 January 1965 to 1 January 2006 without language selection. The medical subject heading (MeSH) and textwords for the following terms were used: hysteroscopy, diagnosis, histology, histopathology, hysterectomy, biopsy, sensitivity and specificity. SETTING: University Hospital. SELECTION CRITERIA: The inclusion criteria were report on accuracy of diagnostic hysteroscopy in women with abnormal uterine bleeding compared to histology collected with guided biopsy during hysteroscopy, operative hysteroscopy or hysterectomy. DATA COLLECTION AND ANALYSIS: Electronic databases were searched for relevant studies and references were cross-checked. Validity was assessed and data were extracted independently by two authors. Heterogeneity was calculated and data were pooled. Subgroup analysis was performed according to validity criteria, study quality, menopausal state, time, setting and performance of the procedure. The pooled sensitivity, specificity, likelihood ratios, post-test probabilities and feasibility of diagnostic hysteroscopy on the prediction of uterine cavity abnormalities. Post-test probabilities were derived from the likelihood ratios and prevalence of intrauterine abnormalities among included studies. Feasibility included technical success rate and complication rate. MAIN RESULTS: One population of homogeneous data could be identified, consisting of patients with postmenopausal bleeding. In this subgroup the positive and negative likelihood ratios were 7.9 (95% CI 4.79-13.10) and 0.04 (95% CI 0.02-0.09), raising the pre-test probability from 0.61 to a post-test probability of 0.93 (95% CI 0.88-0.95) for positive results and reducing it to 0.06 (95% CI 0.03-0.13) for negative results. The pooled likelihood ratios of all studies included, calculated with the random effects model, were 6.5 (95% CI 4.1-10.4) and 0.08 (95% CI 0.07-0.10), changing the pre-test probability of 0.46 to post-test probabilities of 0.85 (95% CI 0.78-0.90) and 0.07 (0.06-0.08) for positive and negative results respectively. Subgroup analyses gave similar results. The overall success rate of diagnostic hysteroscopy was estimated at 96.9% (SD 5.2%, range 83-100%). CONCLUSIONS: This systematic review and meta-analysis shows that diagnostic hysteroscopy is both accurate and feasible in the diagnosis of intrauterine abnormalities.

BACKGROUND: In view of the current emphasis on increasing patient safety and quality control in laparoscopic surgery, there is a growing need to improve laparoscopic training. This study was conducted to investigate if and when residents reached performance standards for basic laparoscopic skills on a boxtrainer and to analyze the current state of implementation of laparoscopic simulators in a gynecological residency curriculum. METHODS: Residents across all 6 years of residency (postgraduate year [PGY] 1-6) were tested once on our boxtrainer by performing five inanimate tasks (pipe cleaner, rubber band, beads, cutting circle, intracorporeal knot tying). A sumscore for the five tasks was calculated for each participant (sum of all scores). Scores were calculated by adding completion time and penalty points, thus rewarding both speed and precision. These data were compared with scores of laparoscopic experts, which were set as performance standards. RESULTS: Of the participants, 111 were residents (7 PGY1, 27 PGY2, 29 PGY3, 28 PGY4, 14 PGY5, 6 PGY6) and 8 were experts. At the end of residency, PGY6 residents reached the performance standard for all tasks except intracorporeal knot tying. It was not until PGY5 that residents reached the performance standard for the pipe cleaner task; PGY1, for rubber band; PGY5, for beads; PGY4, for circle cutting; and PGY6, for sumscore. Throughout residency PGY6 had a mean total of only 3.6 h of simulator training experience. No correlation was found between this previous voluntary simulator training experience and performance on our boxtrainer during this study (sumscore), and between previous voluntary simulator training and total laparoscopic procedures performed. In a combined multivariate analysis, sumscore performance remained significantly associated with the number of laparoscopic procedures performed by residents when they were working as as a primary surgeon (p = 0.002), and not with the cumulative hours of simulator training during residency prior to participating in this study (p = 0.15). CONCLUSIONS: In a current Dutch gynecological residency curriculum, residents do not reach all performance standards for basic laparoscopic skills on the boxtrainer. We conclude that the voluntary simulator training program has a substantial risk to fail and that the implementation of the laparoscopic skills simulator in the current residency curriculum is in its infancy.

BACKGROUND AND AIMS: Survival after radical hysterectomy (RH) for early-stage cervical cancer is good. Hence quality of life (QOL) after treatment is an important issue. Nerve-sparing radical hysterectomy (NSRH) improves QOL by selectively sparing innervation of bladder, bowel and vagina, reducing therapy-induced morbidity. However, the oncological outcome and the functional outcome after NSRH are subjects of debate. We aim to present the best possible evidence available regarding both QOL and survival after NSRH in early-stage cervical cancer. METHODS: Systematic review and meta-analysis on studies comparing NSRH and RH. RESULTS: Forty-one studies were included, and 27 were used for the meta-analysis. There was no difference in 2-, 3- and 5-year overall survival: the risk ratios (RRs) were respectively 1.02 (95% CI 0.99-1.05, n=879), 1.01 (95% CI 0.95-1.08, n=1324) and 1.03 (95% CI 0.99-1.08, n=638). No difference was found in 2-, 3- and 5-year disease-free survival: RR 1.01 (95% CI 0.95-1.05, n=1175), 0.99 (95% CI 0.94-1.03, n=1130) and 1.00 (95% CI 0.95-1.06, n=933) respectively. Post-operative time to micturition was significantly shorter in the NSRH group: standardized mean difference (SMD) -0.84 (CI 95% -1.07 to -0.60). CONCLUSIONS: NSRH can be considered safe and effective for early-stage cervical cancer since short- and long-term survival do not differ from those of conventional RH, while bladder function after NSRH is significantly less impaired.

One hundred ninety-one patients with advanced epithelial ovarian carcinoma were treated with either a combination of doxorubicin and a five-day course of cisplatin alternating with cyclophosphamide and hexamethylmelamine orally for 14 days (CHAP-5) or cyclophosphamide and cisplatin both administered intravenously (IV) on a single day at 3-week intervals (CP). At a median follow-up time of 45 months, treatment with each of these combinations resulted in the same remission rates (80% and 74%, respectively) and exactly the same progression-free survival and overall survival (median, 26 months). Despite adequate hydration, more renal toxicity was encountered in the CP-treated patients than in those who received CHAP-5. Disabling neurotoxicity and severe myelosuppression were encountered more frequently in the patients treated with CHAP-5. Because the toxicity was lower and CP treatment required shorter hospitalization, the single-day regimen was considered preferable for future use. The Karnofsky index was the only independent predictor for response, whereas both this index and the size of residual tumor before chemotherapy were predictive of survival. After correcting for other prognostic factors, it was determined that tumor size associated with improved survival was less than 1 cm. The site of metastases in International Federation of Gynecology and Obstetrics (FIGO) stage IV patients did not influence survival within this category. The results of this study confirm our previous findings that patients with microscopic remnants at second-look have a survival similar to that of patients who are histopathologically free of disease. This makes the significance of so-called pathologically confirmed complete remission questionable. The survival benefit of debulking surgery performed during chemotherapy seems only minimal for patients in whom debulking has already been attempted before treatment. Like others, we have found the CP regimen to have a good therapeutic index.

This report describes a patient with a massive right ventricular infarction, complicated by severe hypoxemia. Contrast echocardiography demonstrated a right to left shunt through a previously asymptomatic atrial septal defect. This phenomenon should be considered as a possible cause of hypoxemia in the presence of right ventricular infarction.

OBJECTIVE: 1) To assess the regression to normal cytology in women with cervical smears diagnosed as atypical squamous or glandular cells of undetermined significance (ASCUS/AGUS) and absence or clearance of human papillomavirus (HPV) infection; 2) To evaluate the association between viral load, semi-quantitatively evaluated, and cytological or histological outcome. MATERIAL AND METHODS: In this cohort study HPV test and biopsy was taken in 148 women with ASCUS/AGUS cytology. After 12-18 months a HPV test and cervical smear were repeated in 121 women. RESULTS: Absence or clearance of HPV showed significantly more regression to normal cytology than persistent or newly acquired infected women, odds ratio 27 (95% confidence interval; 7-103). The viral load of the HPV test at enrollment was not correlated with the follow-up cytological outcome (Spearman correlation coefficient 0.2, p = 0.2). A marked association between viral load and histological outcome at enrollment was shown (Spearman correlation coefficient 0.43, p < 0.0001). CONCLUSION: Absence or clearance of HPV can predict regression to normal cytology. Viral load at enrollment cannot predict cytological regression. There was a marked association between viral load and the underlying CIN at enrollment. However, there was large overlapping of viral loads among the grades of CIN. Therefore, viral load is not a useful parameter to predict high-grade lesions in women with ASCUS/AGUS cytology.
