ABSTRACT- Abnormal cervical cytology includes lesions of the cervix caused due to various infections, hormonal disturbances, premalignant and malignant conditions. Screening of all the symptomatic women complaining of vaginal discharge, irregular menstrual bleeding, dyspareunia, post-coital bleeding or post-menopausal bleeding is necessary for detection and also to pick up any aberration in cervix epithelium i.e. dysplasia or early cervical cancer.
Key-words- Negative for Intraepithelial Lesion or Malignancy, Atypical Squamous Cell of Undetermined Significance, Low grade Squamous Intraepithelial Lesion, High grade Squamous Intraepithelial Lesion, Squamous Cell Carcinoma

INTRODUCTION
Papanicolaou’s observation in 1943, that abnormal cells exfoliated from the cervix can be used to diagnose preinvasive cancer [1] was a landmark achievement in cancer control. Since then cervical and vaginal cytology has expanded in depth and dimensions – by implementing widespread screening programs, from detection of premalignant and malignant lesions to the development of colposcopy guided biopsy and various methods for treating precursor lesions, from refining diagnostic criteria to defining newer diagnostic techniques and establishing role of HPV in cervical carcinogenesis and lately to the development of automated screening device. [2]
On a global basis, cervical cancer is responsible for approximately 2% of the total (weighted) years of life lost.[3] No doubt it stands tall today worldwide as the second most common cancer in females (breast cancer being the first) and the third most common cause of female cancer death. [4-5]
Screening of all the symptomatic women complaining of vaginal discharge, irregular menstrual bleeding, dyspareunia, post-coital bleeding or post-menopausal bleeding is necessary for detection and also to pick up any aberration in cervix epithelium i.e. dysplasia or early cervical cancer.

MATERIALS AND METHODS
The present study was carried out in the Department of Pathology, during the period of 01/01/2015 to 31/12/2015. Women attending gynecology OPD of Government medical college, Chandrapur were included in this study. Detailed history of age, religion, presenting complaints, past history, obstetric history, and contraceptive history was taken.

Materials Required:
     1. Clean glass slide                                 6. Diamond pencil
     2. Ayre’s spatula                                    7. Sim’s speculum
     3. Anterior vaginal wall retractor         8. Biofix spray
     4. Koplin’s jar                                       9. Papanicolau stain
     5. Cover slip                                        10. Mounting medium

Labeling of slides: Slides were labeled with diamond pencil as per serial number.

Sampling: Specimen was collected prior to bimanual examination. Cervix was visualized with the help of normal saline moistened speculum as lubricant gel was known to induce artefactual changes in a PAP smear.[6] The longer portion of Ayre’s wooden spatula was introduced into the external os and rotated through 3600, maintaining firm pressure to obtain material encompassing the whole circumference of the transformation zone. Spatula was withdrawn carefully. The cellular material was spread on the slide in a circular movement to cause uniform spread of cells.

Fixative: The slide was fixed with Biofix spray immediately to avoid artefact. It was allowed to dry. Alternative method of fixation was with 95% ethyl alcohol.

Staining method: Papanicolaou stain

Reporting of smear: Evaluation of smear was done as per The Bethesda System (TBS) 2001 for reporting of smears.

RESULT- Total 1014 cervical smears were obtained from patients who attended Obs / Gynaec OPD. The smears were stained by Papanicolaou stain using the RAPID - PAPTM method, screened and then reported as per The Bethesda System (TBS) 2001.

In the present study, out of 944 satisfactory smears, 908 (96.19%) smears were diagnosed as Negative for Intraepithelial Lesion or Malignancy (NILM) and 36 (3.81%) smears as having epithelial cell abnormalities.
Out of the 908 (96.19%) NILM smears, maximum i.e. 876 (92.80%) showed reactive changes associated with inflammation showing mild nuclear enlargement of squamous cells and plenty of polymorphonuclear leukocytes.

DISCUSSION- The present study was carried out from 01/01/2015 to 31/12/2015. During this period, total 1014 patients attending the OBS/GY OPD complaining of bleeding P/V, discharge P/V, post coital bleeding, post menopausal bleeding, burning micturition or pain in abdomen were screened for the presence of any precancerous lesions of the cervix.

Diagnosis Burkadze [9] Khattak [10] Abdullah [11] Misra [12] Present study
SCC (%) 0.4 0.3 0.37 0.6 0.21


Burkadze reported 20 (0.4%) cases of SCC out of total 4188 cases.
Khattak reported 1 (0.3%) case of SCC out of total 300 cases.
Abdullah reported 21 (0.37%) cases of SCC out of total 5590 cases.
Misra reported 219 (0.6%) cases of SCC out of total 33528 cases.
Two cases of SCC (0.21%) which we reported in the present study, correlates with Khattak.

CONCLUSIONS
The majority of women (75.63%) attending the Obs/Gyn OPD presented with the complaint of white discharge. The most cases detected as Reactive changes with inflammation which were 876 (92.80%).
Epithelial cell abnormalities were diagnosed in 36 (3.81%) cases. Out of these, SCC was seen in 2 cases. (0.21%). High incidence of epithelial abnormality could be attributed to increasing age.
Clinically, healthy cervix is not a criterion for excluding women from abnormal cervical cytology. In the present study, 12 (1.27%) cases of ASCUS and 16 (1.69%) cases of LSIL were diagnosed. Epithelial abnormalities are more commonly found in women belonging to post menopausal age group.
Thus, Papanicolaou smears (Pap test) provide a simple, basic and inexpensive technique for detection of early cancerous and precancerous lesion in otherwise asymptomatic women.
The Bethesda System 2001 for reporting cytology is found to be very useful as it mentions clearly regarding specimen adequacy, provides an effective communication interface among cytologist and clinician for patients evaluation whenever needed.
