Fulltext Secondary Prevention of Cervical Cancer: ASCO Resource-Stratified Guideline Update

Shastri SS, Temin S, Almonte M, Basu P, Campos NG, Gravitt PE, et al.

JCO Glob Oncol, 2022 Sep;8:e2200217.
PMID: 36162041 DOI: 10.1200/GO.22.00217

PURPOSE: To update resource-stratified, evidence-based recommendations on secondary prevention of cervical cancer globally.
METHODS: American Society of Clinical Oncology convened a multidisciplinary, multinational Expert Panel to produce recommendations reflecting four resource-tiered settings. A review of existing guidelines, formal consensus-based process, and modified ADAPTE process to adapt existing guidelines was conducted. Other experts participated in formal consensus.
RESULTS: This guideline update reflects changes in evidence since the previous update. Five existing guidelines were identified and reviewed, and adapted recommendations form the evidence base. Cost-effectiveness analyses provided indirect evidence to inform consensus, which resulted in ≥ 75% agreement.
RECOMMENDATIONS: Human papillomavirus (HPV) DNA testing is recommended in all resource settings; visual inspection with acetic acid may be used in basic settings. Recommended age ranges and frequencies vary by the following setting: maximal: age 25-65 years, every 5 years; enhanced: age 30-65 years, if two consecutive negative tests at 5-year intervals, then every 10 years; limited: age 30-49 years, every 10 years; basic: age 30-49 years, one to three times per lifetime. For basic settings, visual assessment is used to determine treatment eligibility; in other settings, genotyping with cytology or cytology alone is used to determine treatment. For basic settings, treatment is recommended if abnormal triage results are obtained; in other settings, abnormal triage results followed by colposcopy is recommended. For basic settings, treatment options are thermal ablation or loop electrosurgical excision procedure; for other settings, loop electrosurgical excision procedure or ablation is recommended; with a 12-month follow-up in all settings. Women who are HIV-positive should be screened with HPV testing after diagnosis, twice as many times per lifetime as the general population. Screening is recommended at 6 weeks postpartum in basic settings; in other settings, screening is recommended at 6 months. In basic settings without mass screening, infrastructure for HPV testing, diagnosis, and treatment should be developed.Additional information is available at www.asco.org/resource-stratified-guidelines.

Epilepsy in pregnancy - a primary care approach

Zainuddin Z, Tan CK

Family Physician, 2003;12:9-11.

Epilepsy is the most common neurological disorder in pregnancy. The effects of epilepsy include congenital abnormalities which are increased 2-3 fold. The babies born suffer from haemorrhagic disease of newborn. Preconception management and folic acid supplementation is important in optimizing outcome. With close monitoring and proper management, more than 90% of mothers have no complications throughout their pregnancy. Hormonal contraception dosage need to be increased due to the enzyme inducing nature of the anti epileptics drugs.

Comparative study of cytologic and colposcopic findings in preclinical cervical cancer

PMID: 1823091

Seventy-seven patients who had PAP smear cytology and colposcopic examination in a 2-year period between 1988 and 1989 were reviewed. Those with findings indicative or suspicious of malignancy were subjected to biopsy. All 50 patients thus biopsied were confirmed to have preclinical cancer on histological examination. Compared against histology, PAP smear cytology gave an accuracy rate of 90% (5 false negatives) and colposcopy gave an accuracy rate of 94% (3 false negatives). These results demonstrate that the two techniques are useful as screening tests for preclinical cervical cancer. The results are improved if they are used complementarily. However, there was poor specificity in the categorisation of cervical cancer by both methods. This was probably due to the subjectiveness of the two procedures. The study also raised the possibility of a higher incidence of preclinical cervical cancer in the Chinese ethnic group.

Analytical performance of HPV assays on vaginal self-collected vs practitioner-collected cervical samples: the SCoPE study

Saville M, Hawkes D, Keung M, Ip E, Silvers J, Sultana F, et al.

J Clin Virol, 2020 06;127:104375.
PMID: 32361328 DOI: 10.1016/j.jcv.2020.104375

BACKGROUND: In the last decade, human papillomavirus (HPV) testing has been evaluated extensively for cervical screening, with studies finding increased sensitivity compared to cytology. Another advantage of HPV based-screening is the ability to test vaginal samples that can be collected by women themselves. Self-collection has the potential to extend cervical screening coverage by increasing participation rates, particularly among women who are under-screened or have never screened. This could have a significant impact on cervical cancer prevention, as the majority of invasive cervical cancer cases occur among under-screened women. Both the Netherlands and Australia have transitioned their national programs from cytology to HPV as the primary screening test and both countries include a pathway for self-collection.
OBJECTIVES: We evaluated the relative sensitivity for HPV detection of self-collection compared with practitioner-collected cervical specimens in the context of the Australian National Cervical Screening Program (NCSP).
STUDY DESIGN: 303 women aged ≥18 years attending a single tertiary referral centre took their own sample using a flocked-swab, and then had a practitioner-collected sample taken at colposcopy. All samples were tested at a single laboratory on the six PCR-based HPV assays which can be utilised in the NCSP; Roche cobas 4800 and cobas, Abbott RealTime, BD Onclarity, Cepheid Xpert, and Seegene Anyplex.
RESULTS: HPV16/18 results had high observed agreement between self- and practitioner-collected samples on all assays (range: 0.94-0.99), with good agreement for non-HPV16/18 oncogenic HPV types (range: 0.64-0.73).
CONCLUSIONS: Self-collection for HPV-based cervical screening shows good concordance and relative sensitivity when compared to practitionercollected samples across assays in the NCSP.

Analysis and outcome of 502 cases of laser excision cone (LEC) at the Samaritan Hospital for Women, London

Yahya AA, McIndoe GA, Mason WP

Asia Oceania J Obstet Gynaecol, 1992 Dec;18(4):315-8.
PMID: 1492803

When performed based on cytology, histological accuracy of the laser cone specimen improved with the more severe cytology. The incidence of adenocarcinoma in situ is 1.0%. With and without residual disease, the rate of abnormal cytology after laser excision cone are 0.6% and 1.6% respectively. There is good correlation between colposcopic biopsy and cone specimen in the more severe lesions. Out of 139 cases of incomplete excision, only 3 cases had abnormal cytology at follow-up. The complication rates are very low.

Gynaecological cancer screening

PMID: 2712524

One hundred years ago cervical cancer was rapidly fatal, regardless of therapy rendered. Today with cytological screening, early diagnosis is possible and ablative therapy can be instituted in appropriate cases. The advent of coloscopy has helped reduce unnecessary cone biopsy for diagnosis. However, the same cannot be said of the use of cytology for screening endometrial cancer, and often endometrial tissue biopsy is necessary. Ovarian cancer is notoriously silent in its early stages and symptoms if present are generally non-specific. To date there is no other useful and reliable method for its early detection than routine pelvic examination. An annual cytological screening test for cervical cancer will give an opportunity for examination of the breasts, abdomen and pelvis. Screening techniques for female genital tract malignancies are discussed.

This study examines the impact of excision margin status after large loop excision of the transformation zone (LLETZ) under local anaesthetic for high-grade cervical intraepithelial neoplasia (HG-CIN) on the cytological and histological outcomes up to 5 years after treatment.
