RESUMO

Objective: Cancer of the cervix is the second most common cancer in women worldwide. It accounts for 12% of all cancers in females. Our study aims to find out the pattern of cervical cytology on Papanicolaou smear (Pap smear) and its correlation with histopathological findings in the tertiary care referral centre of Western Rajasthan. Materials and methods: This is a prospective study carried out over two years, in which all cervical cytology smears were reported as per the 2014 Bethesda system and abnormal cytology was correlated with histopathological findings in cases where cervical biopsy or total hysterectomy specimens were available. Results:A total of 2291 cervical cytology smears were studied concerning age group, clinical signs and symptoms, and cytology findings. Cervical biopsy correlation was done in 65 patients aged 31-45 (45.61%) years. The mean age of our patients was 41 years. Among the 2291 smears, 181 were unsatisfactory for evaluation. In total, 1982 (86.51%) smears were negative for intraepithelial lesion and malignancy (NILM). Out of 61 abnormal smears, atypical squamous cells of undetermined significance (ASC-US) were seen in 26 (42.62%) cases, atypical squamous cells-cannot exclude high-grade squamous intraepithelial lesion (ASC-H) in nine (14.75%) cases, low-grade squamous intraepithelial lesion (LSIL) in four (6.56%) cases, while nine (14.75%) cases were positive for high-grade squamous intraepithelial lesion (HSIL). Invasive squamous cell carcinoma was seen in seven (11.48%) cases and two (3.28%) cases were positive for adenocarcinoma. Atypical glandular cells of undetermined significance (AGUS) were diagnosed in four (6.56%) cases. In our institutional study, specificity was 81.58% and sensitivity 83.33%. The cytohistopathological correlation was 68.18%, with HSIL (88.89%) having the highest correlation. Conclusion:Various new techniques have emerged in the diagnosis of a range of lesions of the cervix but as these technologies are costly, they cannot be implemented in poor set up countries. In the present scenario, the Pap smear test is considered the best screening method for cervical carcinoma. Biopsy is always considered to be the gold standard for carcinoma cervix provided that it is taken from representative areas.

RESUMO

Background: The International Federation of Gynaecology and Obstetrics working group on menstrual disorders has developed a classification system (PALM-COEIN) for causes of the AUB in non-gravid women. The present study was conducted with the aim to study the two components of this system in clinical practice in general and establish a clinicopathological correlation of AUB with the context of the PALM component in particular. Methodology: The data of 158 patients who underwent hysterectomy for abnormal uterine bleeding in 1 year at the tertiary care Centre of western Rajasthan was collected from old case records and analysed. The patients were initially worked up in the outpatient department with the history and clinical examination, followed by transabdominal or transvaginal ultrasonography depending on the uterine size and the pathology. The patients requiring more detailed pictures were advised computed tomography (CT) scan. All the patients were screened for common medical disorders like thyroid disorders, prolactin levels, and blood sugar levels. Thereafter an endometrial biopsy and liquid-based cytology were done for all the patients to rule out malignancy. The relative contribution of various causes of PALM (structural) and COEIN (functional) components and clinicopathological correlation was analysed. Results: PALM and COEIN components contributed almost equally for AUB when assessed clinically. On the other hand, the histological examination revealed significantly more cases of PALM (structural or anatomical) component of AUB, i.e., 17.2% versus 82.8 %. AUB-L was the commonest (41.1 %) aetiology overall. Conclusion: The PALM-COEIN classification system should consider both the clinical and histopathological diagnoses in women having AUB. It is concluded that the most common cause of AUB is leiomyoma and the most common age group undergoing hysterectomy is the 4th decade. Although the medical treatment options are there, patients of premenopausal age require hysterectomy who do not benefit from medical regimens.

RESUMO

INTRODUCTION: Cervical cancer is the most common cancer in India. Screening for cervical cancer helps in marked reduction of invasive cervical cancers. The low sensitivity of Papanicolaou cytology (Pap smear) and high-risk human papillomavirus (HR-HPV) in excluding high-grade intraepithelial lesion (ASC-H) leads to unnecessary referrals to colposcopy-guided biopsy. The combined cervical cytology screening and HR-HPV have its own limitations and still need further standardization. Using additional biomarkers like staining with p16 and Ki-67 might help in triaging abnormal pap smear. MATERIALS AND METHODS: A prospective, cross-sectional study was performed over a period of 16 months in the Department of Obstetrics and Gynaecology, in collaboration with Department of Pathology. Study was conducted to know the efficacy of immunostaining with p16/Ki-67 in predicting the presence of significant lesion in cases of mild cytological atypia. PAP smears (conventional and LBC) along with P16, Ki-67 and available biopsies were correlated. RESULTS: Liquid-based cytology (LBC) was done in 2134 cases, out of which 46 cases showed abnormal cytological findings such as [22 atypical squamous cells of undetermined significance (ASCUS), 3 low-grade squamous intraepithelial lesion (LSIL), 8 atypical squamous cells cannot exclude high-grade lesion (ASC-H), 6 high-grade squamous intraepithelial lesion (HSIL), 5 squamous cell carcinoma (SCC), 2 adenocarcinoma, 1 atypical glandular cells of undetermined significance (AGUS)]. Immunostaining with p16 and Ki-67 was performed on 38 cases of abnormal cytological smears. Out of 38 abnormal cytology cases, 28 cases had shown co-staining for both p16 and Ki-67, suggestive of true HPV infection of the cells. Of the 38 cases, 07/14 ASCUS, 06/06 HSIL, 07/08 ASC-H, 05/05 squamous cell carcinoma and 02/02 adenocarcinoma also showed dual positivity for p16 and Ki-67. One case of AGUS was diagnosed, but the smear was unsatisfactory for immunocytochemical evaluation and excluded from the study. Three cases of LSIL were also diagnosed on cytological evaluation, and 1 of them however showed positivity for p16 and Ki-67 on immunocytochemistry (ICC). In the ASC-US group, the sensitivity and specificity of the immunostaining in diagnosing CIN2 + lesions were 87.51%, and in LSIL group, the sensitivity and specificity of the immunostaining in diagnosing CIN2 + lesions were 100%. p16/Ki-67 positivity also increased with cytological severity which in turn corresponded with histological findings: it reached from 50% in ASC-US to 100% in both HSIL and SCC categories. CONCLUSION: This immunostaining with p16 and Ki67 can be a useful method in the triaging of the ASC-US and the LSIL group as considering the high sensitivity and specificity values.
