Study of histopathology reports of loop electrosurgical excision procedure of cervical transformation zone and their correlation with preprocedural cervical biopsy and/or cytology: An audit

Introduction: Loop electrosurgical procedure of the transformation zone of the cervix (LEEP) is the preferred method for many investigators for early detection and treatment of high grade intraepithelial neoplasia(HGCIN). Histopathology reports of LEEP should contain information about the diagnosis, presence or absence of neoplasia ( with its grade) and comment on excison margins. Aim: Our aim was to study LEEP reports for its contents and to see their correlation with preprocudure histology and/or cytology report. Results: Between 2011 and 2017, 44 LEEP reports were archived and studied for their contents from our records. Slides were not reviewed. Mean age was 47.66 years (median 47 years). Forty two (( 95.45%) reports mentioned that all the tissue was examined. Deep cut examination was mentioned in 17/44 cases (38.64%). The concordance rate between LEEP and preprocudure histology and /or cytology for CIN II plus diagnosis is 65.9%. A strict definition is used. If, however, diagnoses between inflammation and CIN I, ASC-H and inflammation, and ASC-H and CIN I are considered non discordant, then the concordance rate rises to 72.7 %. The breakup of discordant cases is given. Conclusion: Literature shows wide range of concordance due to variable definitions and variety of reasons; possible reasons are discussed.

SPECTRUM OF CERVICAL LESIONS IN LIQUID BASED CYTOLOGY SMEAR IN A TERTIARY CARE CENTRE IN NORTH INDIA: A 3 YEAR RETROSPECTIVE STUDY

Cervical lesions are one of the most common cause of female morbidity, cervical cancer being the second most common malignancy only after breast in women in India as well as the world. The aim of this study was to analyse the spectrum of cervical lesions in Liquid based cytology and categorizing them according to the Bethesda System for Reporting Cervical cytology. This is a 3 year retrospective study . Total number of cases collected were 1228, of which majority were in the age group of 21-30 years comprising of 450 cases (36.6%) . The most common complain was whitish discharge followed by pain lower abdomen. Out of 1228 cases ,1131 (92.10%) were NILM, 11(0.89%) LSIL,10(0.80%) each of HSIL &ASCUS,5(0.42%) Atypical endocervical cells(NOS), 4(0.35%) SCC and 2(0.16%) Atypical glandular cells(NOS) .55 cases (4.48%) were inadequate. Out of 1131cases of Negative for intraepithelial lesion or Malignancy, 1048 were non -neoplastic and 83 were associated with speci?c infection. Premalignant and malignant lesions of the cervix are very common, therefore proper screening and categorization of cervical lesion is necessary for treatment and follow up,thereby reducing the mortality and morbidity.

Risk factors and prevalence of cervical squamous intraepithelial lesions among women in South India: A community?based cross?sectional study

Background: Cervical cancer in India accounts for one-fifth of the global burden. Well-defined precancerous stages help early detection of the disease. Apart from human papillomavirus, the risk factors include age, education, occupation, early age at marriage and first delivery, abortions, and multiple sexual partners. Prevalence and risk factors for cervical squamous intraepithelial lesions (SIL) among women by Pap smear screening in south India were analyzed through a cross-sectional study. Methods: Women from rural and urban area were motivated by local accredited social health activists to attend pre-fixed Pap smear clinics in government hospitals. Pap smears collected in these clinics were taken to the Regional Cancer Centre, Thiruvananthapuram, processed, and cytology reports were prepared. Multiple logistic regression analysis was used to identify risk factors for SIL and high-grade SIL (HSIL). Results: The number of SIL was 67 out of 10,580 and HSIL was 39. Having higher education (Odds Ratio, OR:0.05(95% Confidence Interval, CI: 0.01-0.2), being married but living single (OR : 5.3, 95%CI:2.4-11.5), Having >2 abortions (OR:21, 95% CI:4.5-24), having younger age at delivery (OR : 0.1, 95% CI:0.01-0.3) and having unhealthy cervix (OR: 16.4, 95% CI:6.2-42.7) were the factors found to be the associated risk factors in multiple regression analysis. Conclusion: Pap smear screening can be focused on women with risk factors such as low education, married but living single, having >2 abortions, younger age at delivery, and unhealthy cervix on per speculum examination.

Correlation of Cervical Pap Smear with Histopathological Diagnosis in Cervical Lesions: A 2 Years Retrospective Study

Introduction: Cervical cancer is one of the most commonforms of cancer worldwide. In developing countries, cancerof uterine cervix is ranked second with a relative frequency of15% of all cancers in women. Screening women with regularPap smears allows diagnosis of treatable pre-invasive lesions.The objective of the study was to correlate the Pap smeardiagnosis with histopathology and to know the accuracy ofPap smears, so as to assess the efficacy of Pap smears indiagnosing cervical lesions.Material and methods: This two year retrospective study wasdone in the department of Pathology in a tertiary care centre,which includes 250 Pap smears for which histopathologicaldiagnosis was also done. Detailed clinical history of patientswas taken from requisition forms received in cytologydepartment along with Pap smears. The cervical biopsies orhysterectomies received from the same patients were alsostudied and then correlated with the diagnosis of Pap smears.Results: Out of 250 Pap smears, maximum patients (32%)belonged to the age group of 41-50 years and were multipara.Maximum cases were reported as NILM (59%),followedby ASCUS (16%), LSIL (15%), HSIL (7%), squamous cellcarcinoma (1.6%) and 0.8% cases of adenocarcinoma werediagnosed. On histopathology, 41.2% cases were diagnosedas chronic cervicitis, 27.2% cases as chronic cervicitis withsquamous metaplasia, CIN I (22.4%),CIN II (4.0%),CIN III(2.8%), squamous cell carcinoma (1.6%) and (0.8)% casesof adenocarcinoma. Overall sensitivity, specificity, positivepredictive value, negative predictive value and diagnosticaccuracy was 75.24%, 97.98%, 96.20%, 85.38% and 88.8%.Conclusion: As per our study, maximum number of casesdiagnosed on Pap smears correlated on histopathology,thereby concluding that Pap smears have an important role indiagnosis of cervical lesions.

Correlation of Pap smear and colposcopic findings in relation to histopathological findings among women attending a tertiary care hospital: a two year study

Background: Cervical malignancy is ranked second among the malignancies in females with breast carcinoma the first. Screening for cervical cancer by conventional cytology and supported by colposcopy and histopathology can easily identify the premalignant lesions and also other non-invasive inflammatory lesions of the cervix. Objective of this study was to find the correlation of Pap smear, colposcopic findings and colposcopic guide biopsy in evaluation of cervical lesions in women and to analyze the various risk factorsMethods: A prospective study for two years was conducted by department of obstetrics among women aged from 20-60 years. Socio demographic data, clinical history and examination were done and findings noted. Pap smear, colposcopy and colposcopic guided biopsy was done and findings were noted and analyzed foe sensitivity, specificity and compared with Pap smear.Results: In present study sensitivity of Pap smear for detecting lesions above LSIL was 28%, specificity 99.32%, PPV was 93.47%, negative predictive value 76.21% and accuracy of Pap smear was 78%. The sensitivity of colposcopy in detection of low grade lesions and above came out to be 80.2%, specificity 82.14%, positive predictive value 66.78%, negative predictive value 86.78% and accuracy of colposcopy was 84.65%.The incidence of preinvasive lesions (LSIL and HSIL) was 33.6% with LSIL (19.2%) and HSIL (14.4%) and of invasive lesions was 9.6%.Conclusions: This study suggests that accuracy of detection of cervical abnormalities is higher when cytology, colposcopic biopsy and colposcopy are used complimentarily in diagnosis of cervical lesions. Colposcopy eliminates the need for repeated follow up as in Pap smear which has low sensitivity.

Analysis of risk factors for residual lesion of HSIL after loop electrosurgical excision procedure / 中国实用妇科与产科杂志

OBJECTIVE: To analyze clinical outcome of high-grade squamous intraepithelial lesion(HSIL)half a year after loop electrosurgical excision procedure(LEEP).METHODS: The retrospective study was carried out on 752 patients who underwent LEEP,with HSIL in the LEEP histopathology from January 2018 to December 2018 at Shanghai First Maternity and Infant Hospital Affiliated to Tongji University to confer the difference between residual group and non-residual group after 6 months of the LEEP conization.TCT,cervical biopsy and high risk HPV test were performed on all patients.RESULTS: Among 752 cases,57(7.6%)cases suffered HSIL residual disease while 695 cases in non-residual group. Before LEEP,HR-HPV 16/18 positive were less in HSIL lesion group showed no difference than those in non-residual group(P>0.05).The residual rate of post-LEEP specimens:CIS and invasive cancer identified only microscopically was higher than that in the AIS group(P<0.05).After LEEP,238 cases with positive margins and 514 cases with negative margins.The residual rate in patients with positive margin and negative margin were 21.1% and 1.4%,(P<0.05).The residual rate in patients with positive endocervical margin,ectocervical margin,unilateral margin and fibrous margin were28.7%,18.9%,17.2% and 26.3%,respectively(P<0.05). The residual rate in patients with second LEEP and non-second LEEP were 29.7% and 6.4%,respectively(P<0.05).The residual rate in patients with TCT≥ ASCUS and normal were 21.9% and 4.4%,respectively(P<0.05).Multivariate regression analysis using the logistic regression model showed CIS,abnormal cytology TCT≥ ASCUS and LEEP with positive margins to be independent risk factors for residual lesions after LEEP(P<0.05).CONCLUSION: Histopathology CIS after LEEP,abnormal cytology(TCT≥ ASCUS)and positive margin are predictors of residual lesion after LEEP with HSIL.

Role of Pap smear in detection of precancerous lesions of cervix-A case study

Background: The pap smear is the screening test for the detection of premalignant lesion of the cervix. It should be done annually in all women of age 35 years and above. Pap smear screening of cervix can significantly reduce the deaths due to cervical carcinoma. Materials and methods: This was a prospective and descriptive study done for the period of 6 months from February 2018 to July 2018. A total of 158 women above the age of 21 years and married were included in the study. A Pap smear test was done after clinical examination in all women and sent to the department of Pathology of our tertiary care centre for cytopathological examination. Results: There were 150 cases with inflammatory smear, 2 cases of ASCUS, 3 cases of LSIL and 3 cases of HSIL. Women who were positive for ASCUS, LSIL and HSIL underwent colposcopy and guided biopsy. Most women with inflammatory smear were of age group 20-40 years, 2cases of ASCUS were of ages 35 years and 38 years, 3cases of LSIL were of age group 35-45 years and 3 cases of HSIL were of age group 45-55years. Conclusion: Thus cervical cancer is a preventable cancer if regular Pap smear screening test is done. It is simple, cost effective, non-invasive and easy to perform screening test for precancerous lesions of cervix.

Integration, Viral Charge and E2 mRNA Levels in the Progresion of Intraepitelial Cervical Lesions / Integración, carga viral y niveles de arn mensajero de e2 de vph 16 en la progresión de lesiones intraepiteliales cervicales

RESUMEN Entre las lesiones intraepiteliales escamosas cervicales (LIE) es importante distinguir aquellas asociadas con mayor riesgo de cáncer de cuello uterino. El objetivo de este trabajo fue evaluar si los niveles de expresión de E2 del VPH16 en mujeres con LIE y con evidencia de integración viral se asocian con el grado de la lesión. Se analizaron 109 cepillados cervicales positivos para VPH 16 provenientes de 19 mujeres sin LIE, 45 mujeres con LIE de bajo grado (LIEBG) y 45 mujeres con LIE de alto grado (LIEAG). Se cuantificó el número de copias de ARNm de E2 y de los genes E2 y E6 mediante PCR en tiempo real para determinar la carga viral (E6) y la proporción E2/E6 para evaluar la integración viral. Se encontraron frecuencias similares de expresión de E2 en LEIBG y LEIAG 15/45 (33 %), la frecuencia en mujeres sin lesión fue menor 3/19 (15,8 %), todos los casos en los que se observó expresión del gen E2 tenían mezcla de ADN viral episomal e integrado. La carga viral aumentó significativamente a mayor grado de la lesión (ρ =0,049), mientras que la proporción E2/E6 disminuyó (ρ=0,049). El análisis ROC mostró una baja capacidad de los tres parámetros virales para distinguir entre lesiones de bajo y alto grado. En conclusión, aunque las lesiones con presencia de ADN viral mixto e integrado y expresión de E2 podrían estar en menor riesgo de progresión, y la carga viral y la integración se relacionaron con mayor gravedad de la lesión, su valor clínico como biomarcadores de LEIAG es limitado.

ABSTRACT It is important to distinguish among squamous intraepithelial lesions (SIL) those associated with increased risk cervical cancer. Our aim was to evaluate if the expression level of gen E2 in women with SIL and evidence of viral integration is associated to the grade of lesion. Cervical scrapes HPV16 positive from 19 women with normal histology, 45 women with low-grade SIL (LSIL) and 45 women with high-grade SIL (HSIL) were analyzed. Real-time PCR was used to quantify the mRNA of E2 and E2 and E6 genes to calculate viral load (E6) and the ratio E2/E6 to assess viral integration. Similar frequencies of E2 expression were found in LSIL and HSIL15/45 (33 %), the frequency in women without SIL was lower 3/19 (15.8 %), and all cases with E2 gene expression had mixed episomal and integrated viral DNA. The viral load increased significantly with the grade of SIL (ρ= 0.049), while E2/E6 ratio decreased (ρ=0.049). The ROC analysis showed low capacity of the three viral parameters analyzed to distinguish between low and high grade SIL. In conclusion although SIL with mixed and integrated viral DNA with E2 expression could be at lower risk of progression, and viral load and integration were associated with higher severity of the lesion, its clinical value as biomarkers of HSIL is limited.

Previamente, se desarrolló una metodología diagnóstica para lesiones preneoplásicas y neoplásicas de células de cuello uterino, a partir de medidas euclidianas y fractales simultáneas. En este trabajo, el objetivo era confirmar la concordancia diagnóstica de la metodología en células normales y en diferentes estadios de lesión celular. Se tomaron fotografías de 60 células del epitelio escamoso cervical: 10 normales, 10 ASCUS, 20 con lesión intraepitelial de bajo grado (LEIBG) y 20 con lesión de alto grado (LEIAG). Se realizaron medidas de dimensión fractal y del espacio de ocupación de la superficie y el borde del núcleo y citoplasma en el espacio fractal de Box Counting, estableciendo su diagnóstico físico-matemático. Las medidas de la superficie del núcleo estuvieron para normalidad, entre 305 y 651; para ASCUS, entre 1293 y 4588; para LEIBG, entre 986 y 4873 y para LEIAG, entre 567 y 2311. La resta de las fronteras Citoplasma-Núcleo, se encontró entre 238 y 477, para normalidad; entre 185 y 417, para ASCUS; entre 131 y 342, para LEIBG y entre 43 y 117, para LEIAG. Fueron hallados valores de sensibilidad y especificidad del 100%; la razón de probabilidad fue de 0 y el coeficiente kappa de 1. Se confirmó la concordancia diagnóstica a nivel clínico del método físico-matemático, cuantificando de manera objetiva y reproducible el grado de lesión de células de cérvix y estableciendo un diagnóstico objetivo para las células ASCUS, a partir de medidas fractales y euclidianas simultáneas, que mejora los métodos cualitativos de clasificación.

A diagnostic methodology for preneoplastic and neoplastic lesions of cervical cells from simultaneous fractals and euclidean measures was developed. In this work the objective was to confirm the diagnostic concordance of the methodology in normal cells and in different stages of progression to disease. For this, 60 photographs of cervical squamous epithelium cells were taken: 10 normal, 10 ASCUS, 20 with low grade - squamous intraepithelial lesion (L-SIL) and 20 high-grade lesion (H-SIL). Measures of fractal dimension and space occupancy of the surface and the edge of the nucleus and cytoplasm were performed in Box Counting Fractal space, establishing their physical-mathematical diagnosis. Measurements of the nucleus surface for normality were between 305 and 651, for ASCUS between 1293 and 4588, for L-SIL, between 986 and 4873 and for H-SIL between 567 and 2311. The subtraction of Cytoplasm-Nucleus border was found between 238 and 477 for normality; between 185 and 417 for ASCUS; between 131 and 342 for L-SIL and between 43 and 117 for H-SIL, finding sensitivity and specificity of 100%, likelihood ratio of 0 and kappa coefficient of 1. Conclusions: the diagnostic concordance at clinical level of the physical-mathematical method was confirmed, objective and reproducible quantifying the degree of injury of cervical cells and establishing an objective diagnosis for ASCUS cells from simultaneous fractals and euclidean measures, which improves qualitative classification methods.

Impact of human papillomavirus multi-infections on the risk of high-grade squamous intraepithelial lesion and invasive cervical cancer / 实用医学杂志

Objective To determine the incidence rate of HPV infection or multi-infections at different stages of cervical lesions in the development of cervical cancer , and the impact of specific types of HPV multi-infections on the risk of cervical cancer. Methods 103 samples of cervical tissues were detected and then divid-ed into ICC/HSIL group and LSIL/NILMF group according to the degree of pathological changes. HPV type was determined by PCR product sequencing. E6 nested multiplex PCR was performed to detect HPV multi-infections. Odds ratios were calculated to determinate the association between the sample category (LSIL/NILM or ICC/HSIL) and the specific types of HPV multi-infections. Results In HPV-positive samples, the rate of multi-in-fections had no significant differences between the two groups. Coinfection of HPV68 with HPV16 increased the risk of ICC/HSIL, as compared with HPV16 or HPV68 infection alone. Conclusions High-risk HPV coinfec-tions has a higher risk to induce ICC/HSIL than does HPV infection alone.

Study of PAP smear examination in patients complaining of leucorrhoea – A 2 years prospective study in a teaching hospital

Background: Leucorrhoea is the clinical evidence of infection and can be treated satisfactorily whenever diagnosed. Occurrence of cervical cancer associated with discharge/leucorrhoea can be easily prevented if detected early. Majority of patients attending hospital present with varying degree of vaginal discharge and cytological monitoring of these subjects is mandatory to know any cellular changes in the cervical epithelium as well as the presence of any sexually transmitted diseases (STD’s) in the genital tract. Materials and methods: This research study was done at Malla Reddy Institute of Medical Sciences (MRIMS), Suraram, Hyderabad, Telangana State, India for a period of 2 years. A total of 500 cases were included in the study with women of age ranging from 20-50 years, complaining of Leucorrhoea. As told by the patients on questioning as a part of clinical history, the Leucorrhoea was found to be of different types white discharge, yellowish discharge, greenish discharge; blood stained and fouls smelling discharge. Smears were taken with a thorough history in particular reference to age at first child birth, parity, personal and genital hygiene, history of husband suffering from any sexually transmitted diseases, vaginal discharge, mass per vaginum, duration of labour and history of sexually transmitted diseases were elicited. Results: In our study of 500 cases, 348 (69.6 %) cases showed reactive cellular changes associated with repair (Inflammatory smear), 56 (11.2%) cases were due to various infectious agents, 32 cases P.

Conclusion: A Pap test (Pap smear) is a quick and simple test that checks for changes to the cells of your cervix that may lead to cervical cancer. Pap smear reduces the mortality and morbidity with cervical cancer. This cytological screening should gain much popularity and should be accessible to all. It is recommended as part of routine medical examination in gynecological practice.

The role of HPV type 16 E6 variant in persistent infection and recurrence of cervical HSILs after conization / 实用医学杂志

Objective To explore the role of humall papillomavims (HPV) type 16 E6 variants in the persistent infection and recurrence of the cervical high-grade squamous intraepithelial lesion (HSIL) after conization. Motheds During May to June 2012, 100 HSIL patients with HPV16 positive but negative at the margin after Loop electrosurgical excision procedure (LEEP) were selected from Shanghai People′s Hospital of Pudong District. The gene sequencing was done to the E6. The patients were followed up for 2 years. The E6 gene sequencing was done again to detect the HPV16 variants among those with persistent infections and recurrence. Results Among the 100 cases, E6 variants were detected, 81% of them HPV E6 variants Asian prototype, 14% European variant; 2% European prototype (EP) and 3% African variant 1. LEEP for Asian prototype was susceptible to the clearance of HPV16 (P < 0.001). The European variants of T350G, and A442C were correlated with persistent infection and recurrence (P < 0.001). Conclusion The HPV16 variant is closely related to the HSIL incidence. HSIL caused by HPV16 in Pudong New Area of Shanghai belong to the Asian type variant. The European variants of E6 , T350G/A442C were likely related to the recurrence of HPV16.

Lesões cervicais e infecção pelo papilomavirus humano no sistema prisional da cidade de São Paulo, Brasil / Cervical lesions and human papillomavirus infection in women at a prisional system in São Paulo city, Brazil

A relação entre o câncer cervical e a infecção pelo Papilomavírus Humano (HPV) está bem estabelecida. Múltiplos parceiros e múltiplas práticas sexuais são os fatores de risco associados à infecção pelo HPV. Existe uma grande probabilidade em que as mulheres internas em presídios tenham uma maior suscetibilidade de adquirir a infecção genital. A avaliação de alterações celulares, pelo exame de Papanicolaou, e identificação molecular de DNA-HPV de alto risco são utilizadas para a detecção e prevenção do câncer cervical. Quatrocentas e nove amostras cervicais de mulheres internas, nopresídio feminino da cidade de São Paulo, com idade entre 18 e 60 anos, foram analisadas, em 2006. Os achados celulares foram classificados com base no Sistema Bethesda (2001). O DNA-HPV foi identificado pelo PCR convencional, empregando os primersuniversais MY09/11, e os tipos identificados por PCR/RFLP, utilizando enzimas de restrição. Vinte e sete (6,60%) dos 409 esfregaços das internas do sistema penal revelaramLesões Escamosas Intraepiteliais de Baixo Grau (LSIL), 3 (11,11%) mostram alterações compatíveis com Lesões Escamosas Intraepiteliais de Alto Grau (HSIL), 5 (18,53%) exibiram Atipias Escamosas de Significado Indeterminado (ASC-US), 1 (3,70%) mostrou Células Glandulares Atípicas (CGA) e 1 (3,70%) revelou Carcinoma de Células Escamosas. DNA-HPV de alto risco foi identificado em 12 (44,43%) amostras (HPV 16, 18, 31, 33, 34, 39 e 61). Oito (29,62%) amostras revelaram infecção por HPV de baixo risco (HPV 6b). O presente estudo detectou uma alta prevalência de LSIL e HSIL associada à presença de DNA-HPV de alto risco, nas mulheres internas no sistema prisional.

The association between cervical cancer and Human PapillomavirusInfection (HPV) has been determinated. Multiple partners andmultiple sexual practices are risk factors associated with HPVinfection. There is a high probability that women resident in prisionscould be more susceptible to acquire genital HPV infection. Thescreening of cellular changes by pap-smear and the molecularidentification of high risk DNA-HPV is usefull for the detection andprevention of cervical cancer. Four hundred nine samples of cervicalsmear from women resident in a prisional system in São Paulo,between 18 to 60 years old were analyzed in 2006. The cellularresults were reported according to the Bethesda System Terminology,2001. The DNA-HPV detection was made by Conventional PCR usingConsensus Primers MY 09/11 and the HPV types were identify byPCR-RFLP using restriction endonuclease enzymes.Twenty seven(6,60%) out of 409 pap-smears samples showed pre malignant lesion.Seventeen (62,96%) out of these 27 samples revealed Low Squamous Intraepitheal Lesion (LSIL), 3 (11,11%) showed changessuggestive of High Squamous Intraepithelial Lesion (HSIL), 5(18,53%) samples presented Atypical Squamous Cells ofUndetermined Significance (ASC-US), 1 (3,70%) sample had AtypicalGlandular Cells (AGC), and 1 (3,70%) sample showed CervicalSquamous Carcinoma. High Risk DNA-HPV was identified in 12(44,43%) (HPV 16, 18, 31, 33, 34, 39 and 61). Eight (29,62%) samplesrevealed the low risk for neoplasic lesion subtype HPV-6b. Thepresent study reveal a high prevalence of LSIL and HSIL associatedwith the presence of High-risk DNA-HPV in women resident in aprisional system.

Physical state & copy number of high risk human papillomavirus type 16 DNA in progression of cervical cancer.

Background & objectives: High-risk human papilloma virus (HR-HPV) infection and its integration in host genome is a key event in malignant transformation of cervical cells. HPV16 being a dominant HR-HPV type, we undertook this study to analyze if viral load and physical state of the virus correlated with each other in the absence of other confounding variables and examined their potential as predictors of progressive cervical lesions. Methods: Both, viral load and integration status of HPV16 were determined by real time URR PCR and estimation of E2:E6 ratio in a total of 130 PGMY-RLB -confirmed, monotypic HPV16-infected cervical DNA samples from biopsies of cytology-confirmed low grade (LSIL, 30) and high grade (HSIL, 30), and invasive carcinoma, (squamous cell carcinoma SCC, 70) cases. Results: Investigation of DNA samples revealed a gradual increase in HPV16 viral load over several magnitudes and increased frequency of integration from LSIL to HSIL and HSIL to invasive cancer in relation to the severity of lesions in monotypic HPV16-infected cervical tissues. In a substantial number of precancer (11/60) and cancer cases (29/70), HPV16 was detected in concomitant mixed form. The concomitant form of HPV16 genome carried significantly higher viral load. Interpretation & conclusions: Overall, viral load and integration increased with disease severity and could be useful biomarkers in disease progression, at least, in HPV16-infected cervical pre-cancer and cancer lesions.
