The role of cytological follow-up after radical vaginal trachelectomy for early-stage cervical cancer.

OBJECTIVES: To identify whether recurrences were picked up by cytology alone after radical vaginal trachelectomy and to determine the false-positive rate of abnormal cytology. METHODS: Retrospective collection of patients from the cancer registry since radical vaginal trachelectomy was first performed in Bristol in 1999. All cytology results were collated and re-reviewed by a senior consultant cellular pathologist at the cytopathology centre in Southmead Hospital, Bristol. Cytology results and pathology and survival data are discussed, and any downgrading or upgrading of reports is reviewed. RESULTS: Eighteen women were identified and 80 isthmic cytology samples were reviewed. Only one recurrence has occurred. Lower uterine segment sampling was apparent in 25 samples and other endometrial cells in 21 samples: thus 58% showed endometrial cell sampling. Odd metaplastic cells from the newly formed transformation zone were found in 25 samples (31%). Fifteen (19%) showed significant inflammation, two with actinomyces. After cytology review, seven of 80 reports were changed: two between negative and inadequate, two borderline changes in endocervical cells and one mild dyskaryosis were downgraded to negative, and two cases reported as ?glandular neoplasia were changed to squamous cell carcinoma and negative, respectively. CONCLUSIONS: Cytology reporting may be challenging after trachelectomy. Cytology in our series did not add to the diagnosis of recurrence in the one case in which it occurred. We propose a pragmatic follow-up regime, and discuss the importance of the centralization of cytology reporting in these patients.

Hormone replacement therapy after endometrial cancer.

Endometrial cancer is the fourth most common female cancer in the UK and the most common gynaecological cancer. Quality of life and symptom control needs to be considered in women who enter a surgically induced menopause. Hormone replacement in this population has been controversial to date. The current evidence regarding the safety of estrogen only and combined hormone replacement therapy is discussed in this review. The use of topical vaginal therapies, alternate therapies and the current data regarding testosterone use for symptom control is also outlined.

Review: optical micrometer resolution scanning for non-invasive grading of precancer in the human uterine cervix.

Management of cervical precancer is archetypal for other cancer prevention programmes but has to consider diagnostic and logistic challenges. Numerous optical tools are emerging for non-destructive near real-time early diagnosis of precancerous lesions of the cervix. Non-destructive, real-time imaging modalities have reached pre-commercial status, but high resolution mapping tools are not yet introduced in clinical settings. The NCBI PubMed web page was searched using the keywords 'CIN diagnosis' and the combinations of 'cervix {confocal, optical coherence tomography, ftir, infrared, Raman, vibrational, spectroscopy}'. Suitable titles were identified and their relevant references followed. Challenges in precancer management are discussed. The following tools capable of non-destructive high resolution mapping in a clinical environment were selected: confocal microscopy, optical coherence tomography, IR spectroscopy, and Raman spectroscopy. Findings on the clinical performance of these techniques are put into context in order to assist the reader in judging the likely performance of these methods as diagnostic tools. Rationale for carrying out research under the prospect of the HPV vaccine is given.
