INTRODUCTION
• The Bethesda system (TBS) :
• It is a system of reporting cervical or vaginal cytologic diagnoses
,used for reporting Pap smear results
• Introduced in 1988 , revised in 1991 , 2001 , 2014.
THE BETHESDA SYSTEM (TBS)
• SPECIMEN TYPE
• SPECIMEN ADEQUACY
• GENERAL CATEGORIZATION (optional)
• INTERPRETATION / RESULT
• ANCILLARY TESTING
• AUTOMATED REVIEW
• EDUCATIONAL NOTES AND SUGGESTIONS (optional)
• The Bethesda system
• SPECIMEN TYPE
Indicate conventional smear (Pap smear)
vs. liquid-based preparation
vs. other.
• Conventional Pap
In a conventional Pap smear , samples are smeared directly onto a
microscope slide after collection.
• Liquid based cytology
 The sample of (epithelial) cells is taken from the Transitional Zone
 Liquid-based cytology uses an arrow-shaped brush
 The cells taken are suspended in a bottle of preservative &
transported to the laboratory .

2/4
2/4
• Colposcopy is recommended (if LSIL)
• Loop electrosurgical excision or colposcopy for HSIL.
• ASCUS….. (HPV testing/ Repeat cytology in 1 year
If HPV negative - cotesting - cotesting at 3 years.
If HPV positive - colposcopy.
If 1 year cytology is negative - routine screening
• NILM – Repeat cotesting in 3 years is preferred.
• NILM – after 65 years – No further screening is required if
prior negative screening.

Notas del editor

  1. The Bethesda system (TBS) is a system for reporting cervicalor vaginal cytologic diagnoses,used for reporting Pap smearresults. It was introduced in 1988, and revised in 1991 and 2001. The name comes from the location (Bethesda, Maryland) of the conference that established the system. Cervical cytology is the most successful cancer prevention programme
  2. Liquid-based cervical cytology was developed to improve the diagnostic reliability of Papanicolaou (Pap) smears. Conventional Pap smears can have false-negative and false-positive results because of inadequate sampling and slide preparation, and errors in laboratory detection and interpretation. However, liquid-based cytology rinses cervical cells in preservatives so that blood and other potentially obscuring material can be separated. It also allows for additional testing of the sample, such as for human papillomavirus (HPV). The comparative accuracy of each technique has been studied extensively and has yielded conflicting results; recent systematic reviews reported that there is no convincing evidence to recommend one technique over the other. Siebers and colleagues designed this prospective study to compare the histologic detection rates and positive predictive values of conventional Pap smears and liquid-based cervical cytology. Routine cytopathologic evaluation Performed:  Monday - Friday Reported:  Within 5 days Use:  A Pap smear examines the cells of the cervix and detects cell abnormalities. Both, cancerous and precancerous cells can be detected. Pap tests are recommended in women ages 21 - 64, every two years with normal Pap results. Vaginal Pap smears can also be performed but must be noted on the requisition. Result:  Interpretive report Specimen Requirements:  Collection and Transportation: In general, the ideal time to perform a Pap test is more than 12 days after the last  menstrual period and 24 hours or more after douching or sexual intercourse. Perform the test before a bimanual exam. The proper technique for a conventional Pap smear, using the scrape and cytobrush and/or swab, is as follows: Place the patient in the lithotomy position. Using an unlubricated vaginal speculum (saline may be used as a lubricant) visualize the cervix as fully aspossible. Be sure the slide being used is already labeled in pencil with the proper patient information and site of sample. Label the slide(s) with the patient’s first and last name, date of birth, and specimen source directly on the frosted end of the glass, in pencil, before beginning the procedure. The laboratory will not accept unlabeled slides. A rare patient may have 2 cervices and then designate as right or left. If on visual inspection, the cervix is coated with excessive mucus, inflammatory debris, blood or other contaminants, lightly dab the surface with a salinemoistened 4x4 or swab to remove obscuring substances that will make the smear unsatisfactory for interpretation without disturbing the surface epithelium. After visualization of the cervix is accomplished, insert the cytobrush into the endocervical canal and rotate it half a turn. Withdraw the cytobrush and spread the collected material quickly and evenly onto the half of the slide opposite the frosted end. The endocervical mucus will prevent air-drying during collection of the subsequent cervical component.Using the extended-tip spatula, scrape material with the spatula from the whole circumference of the cervix (in a 360° turning motion). Withdraw the spatula and spread the collected material quickly and evenly onto the half of the slide adjacent to the frosted end. Fix the specimen immediately by dropping the slide into fixative or spraying it with fixative, holding the spray bottle approximately 8 to 12 inches from the slide. Complete the cytology test request form, including relevant clinical information. The importance of immediate and generous fixation with Pap fixative cannot be overstated. The smear should be left on a level surface (not at an angle) and allowed to dry if spray-fixed. If an accurate hormonal assessment is necessary (MI), a lateral vaginal wall scraping should be submitted separately. Do not submit for hormonal assessment if there is clinical evidence of active inflammation. Avoid using KY Jelly lubricant on the speculum (Use warmed water instead.). Be mindful that powder from gloves doesn’t contaminate the specimen or glass slides. If using powdered gloves rinse them after placing on your hands under running water. Send the smear to the laboratory in a protective slide holder, along with the matched requisition properly inserted in biohazard bag. The laboratory will proceed with the staining, screening and review of the specimen by a cytotechnologist and/or pathologist, according to established guidelines. Do not place thick mucus plugs on the Pap slide, as this interferes with staining and obscures important cellular detail.
  3. Liquid based cytology— The sample of (epithelial) cells is taken from the Transitional Zone; the squamo-columnar junction of the cervix, between the ecto and endocervix. Liquid-based cytology uses an arrow-shaped brush, rather than the conventional spatula. The cells taken are suspended in a bottle of preservative for transport to the laboratory, where using Pap stains it is analysed.

In the USA, cervical screening is usually performed using the Pap test (or 'smear test'),[16] though the UK screening programmes changed the screening method to liquid-based cytology in 2008.[17] Conventional cytology[edit] Main article: Pap test In the conventional Pap smear, the physician collecting the cells smears them on a microscope slide and applies a fixative. In general, the slide is sent to a laboratory for evaluation. Studies of the accuracy of conventional cytology report:[18] sensitivity 72% specificity 94% Liquid-based monolayer cytology[edit] Since the mid-1990s, techniques based on placing the sample into a vial containing a liquid medium that preserves the cells have been increasingly used. Two of the types are Sure-Path (TriPath Imaging) and Thin-Prep (Cytyc Corp). The media are primarily ethanol-based for Sure-Path and methanol for ThinPrep. Once placed into the vial, the sample is processed at the laboratory into a cell thin-layer, stained, and examined by light microscopy. The liquid sample has the advantage of being suitable for high-risk HPV testing and may reduce unsatisfactory specimens from 4.1% to 2.6%.[19] Proper sample acquisition is crucial to the accuracy of the test, as a cell that is not in the sample cannot be evaluated. Studies of the accuracy of liquid based monolayer cytology report: sensitivity 61%[20] to 66%,[18] (although some studies report increased sensitivity from liquid-based smears[19]) specificity 82%[20] to 91%[18] Human papillomavirus testing[edit] Human papillomavirus (HPV) infection is a cause of nearly all cases of cervical cancer.[21] Most women will successfully clear HPV infections within 18 months. Those that have a prolonged infection with a high-risk type[22] (e.g. types 16, 18, 31, 45) are more likely to develop Cervical Intraepithelial Neoplasia, due to the effects that HPV has on DNA. The English National Health Service now includes "HPV triage" in its screening programme. This means that if initial screening test shows borderline results or low-grade abnormal cells, a further test for HPV is made on the sample. If this shows HPV is present, the patient is called for a further examination, but if no HPV is present the patient resumes the usual screening schedule as if no abnormalities had been found.[23] Studies of the accuracy of HPV testing report: sensitivity 88% to 91% (for detecting CIN 3 or higher)[20] to 97% (for detecting CIN2+)[24] specificity 73% to 79% (for detecting CIN 3 or higher)[20] to 93% (for detecting CIN2+)[24] By adding the more sensitive HPV test, the specificity may decline.[25] If the specificity does decline, the result is increased numbers of false positive tests and, for many women that did not have disease, an increased risk for colposcopy, an invasive procedure[26] and unnecessary treatment. A worthwhile screening test requires a balance between the sensitivity and specificity to ensure that those having a disease are correctly identified as having it and those without the disease are not identified as having it. Regarding the role of HPV testing, randomized controlled trials have compared HPV to colposcopy. HPV testing appears as sensitive as immediate colposcopy while reducing the number of colposcopies needed.[27] randomized controlled trial have suggested that HPV testing could follow abnormal cytology[20] or could precede cervical cytology examination.[24] A study published in 2007 suggested that the act of performing a Pap smear produces an inflammatory cytokine response, which may initiate immunologic clearance of HPV, therefore reducing the risk of cervical cancer. Women that had even a single Pap smear in their history had a lower incidence of cancer. "A statistically significant decline in the HPV positivity rate correlated with the lifetime number of Pap smears received."[28] HPV testing can reduce the incidence of grade 2 or 3 Cervical Intraepithelial Neoplasia or cervical cancer detected by subsequent screening tests among women 32–38 years old according to a randomized controlled trial.[29] The relative risk reduction was 41.3%. For patients at similar risk to those in this study (63.0% had CIN 2-3 or cancer), this leads to an absolute risk reduction of 26%. 3.8 patients must be treated for one to benefit (number needed to treat = 3.8). Click here to adjust these results for patients at higher or lower risk of CIN 2-3.
  4. Satisfactory for evaluation (describe presence or absence of endocervical/transformation zone component and any other quality indicators, e.g., partially obscuring blood, inflammation, etc.) Unsatisfactory for evaluation …(specify reason) Specimen rejected/not processed (specify reason) Specimen processed and examined, but unsatisfactory for evaluation of epithelial abnormality because of (specify reason)
  5. Seen usually in proliferative phase of menstrual cycle & in presence of irritation .nucleus cross sectional area is 10-15 Mm2.abundant cytoplasm,kh granules.superficial or outer most layer of the cervical epithelium
  6. Middle / intermidiate layer of cervical epithelium,in secretory phase of menstrual cycle - both superficial & intermediate. Intermediate layer is prominent in pregnancy ,with use of progestational agents. Nucleus cross sectional area is 35Mm2.
  7. Nucleus of para basal cell – cross sectional area 50Mm2.cells predominate in post menopausal and post partum status.cytoplasmic area is smaller & the N:C ratio is higher ,cytoplasmic texture is more granular & dense.
  8. Honey comb pattern-viewed enface , picket fence –side view
  9. Exfoliated endometrial cells are a normal finding in cervical cytology preparations from a woman of reproductive age group and are commonly seen during menses and proliferative phase of menstrual cycle.in post menopausal women presence of endometrial cells are considered abnormal and raise the suspicion of endometrial neoplasia . In 2014 bethesda system exfoliated endometrial cells should be reported in a women 45 age or older. Endometrial cells are seen from D1 – D12 of menstrual cycle . Exodus pattern noted from D6-D10. In liquid based preparation , exfoliated endometrial cells may be slightly larger , with more easily visible nucleoli and enhanced chromatin details compared to conventional smear preparations . Histiocytes are often seen in association with exfoliated endometrial cells.their presence has no significance in predicting the presence of endometrial carcinoma .histiocytes have folded,grooved ,kidney shaped nucleus & moderate amount of vacuolated cytoplasm. Some times endometrial cells seen as naked nuclei . These naked nuclei arranged in clusters must be differentiated from mature small lymphocyte clusters.lymphoid clusters are looser & more irregularly shaped ,& small mature lymphocytes have coarser chromatin than endometrial cells .
  10. Spider cells - cells having spindle shaped cytoplasmic projections ,due to disruption of the cohesion of cellular attachments by the force of smearing procedure , The process of metaplasia represents replacement of one type of epithelium with other as a protective response . N:C ratio 50%, smooth nuclear contours, evenly distributed chromatin .the stimuli for this change - infection , inflammation , trauma
  11. Normally cervix lined by nksse , keratotic changes occur as a protective reactive phenomenon or in association with HPV, HYPERMATURATION of the native squamous epithelium .
  12. TUBAL METAPLASIA is a metaplastic phenomenon in which the normal endocervical epithelium is replaced by an epithelium that recapitulates that of the normal fallopian tube. This metaplastic epithelium includes several cell types - ciliated cells ,peg cells ,globlet cells. Tubal metaplasia is a frequent finding in the upper endocervical canal /lower uterine segment, PRESENCE OF CILIA IS CHARACTERISTIC
  13. ATROPHY is a normal aging phenomenon associated with lack of hormonal stimulation leading to thinned epithelium consisting of immature parabasal / basal cells . Globular collections of basophilic amorphous material – blue blobs- reflect degenerated parabasal cells / inspissated mucus
  14. Altered hormone stimulation – intermediate cell predominates, prominent glycogen with flattened boat like appearance , navicular cells navicular cells have thickened borders & form dense clusters , Decidual cells - hormonally stimulated endocervical / endometrial stroma Criteria cells occur singly & rarely in small clusters cytoplasm abundant granular / finely vacuolated ,cytoplasmic processes nuclei - 35 -50 Mm2.,lobulated /multi nucleated chromatin fine – normo/ hyperchromatic nuclear membrane - smooth nucleoli - prominent , basophilic Cytotrophoblast - placenta derived criteria - cells occur singly / in clusters ,cytoplasm – scanty with prominent vacuoles ,nucleus - enlarged ,high N:C ratio, hyperchromasia background – highly inflammed & bloody SYNCYTIOTROPHOBLAST - late pregnancy & post partum rare months after delivery criteria – large multinucleated cells - >=50 nuclei tapering of granular cytoplasm at one end of the cell nuclei - normochromatic ÁRIAS stella reaction Glandular epithelial cells are involved Criteria – cells in singles / clusters cytoplasm vacuolated N:C ratio- high nucleus- lare ,hyperchromatic ,irregular,prominent nucleoli, background - inflammatory -leukophagocytosis
  15. Reparative changes more pronounced in conventional smear as the cells flatten out against the slide,inflammatory background is more pronounced.
  16. It is a form of chronic cervicitis - formation of mature lymphoid follicles in subepithelium In cytosmear – polymorphous population of lymphocytes In liquid based preparation – lymphocytes as loosely aggregated clusters / scattered in singles In conventional preparations - lymphocytes seen in clusters in strands of mucus
  17. radiation associated changes resolve with in 6 months following therapy
  18. signet ring appearance- large vacuoles in cytoplasm displace the nucleus
  19. in liquid based preparation : organisms smaller, nuclear & cytoplasmic eosinophilic granules ,flagella are preserved in conventional smears : increased neutrophilic infiltrate , flagella are less often identifiable
  20. Clue cells - individual squamous cells covered by a layer of coccobacilli, absence of lactobacilli Lactobacilli are GP ,rod shaped bacteria BV associated with PID , PRETERM BIRTH , post op gynecologic infections
  21. Tangled filamentous organisms with acute angle branching , background – PML’s Liquid based preparation : strands of actinomycotic organisms tend to be finer & more delicate –as proteineceous material is washed away, neutrophils in the back ground decreased In conventional preparations : aggregation of proteineceous material tend to form a coating / club at the periphery of actinomyces filaments
  22. HERPES cytopathic effect - multinucleation , molding , margination of chromatin nucleus – ground glass appearance- due to intra nuclear viral particles & enhancement of nuclear envelope caused by peripheral margination of chromatin
  23. In immunocompromised individuals
