Optimising follow-up strategy based on cytology and human papillomavirus after fertility-sparing surgery for early stage cervical cancer: a nationwide, population-based, retrospective cohort study.

BACKGROUND: The optimal follow-up strategy to detect recurrence after fertility-sparing surgery for early stage cervical cancer is unknown. Tailored surveillance based on individual risks could contribute to improved efficiency and, subsequently, reduce costs in health care. The aim of this study was to establish the predictive value of cervical cytology and high-risk human papillomavirus (HPV) testing to detect recurrent cervical intraepithelial neoplasia grade 2 or worse (CIN2+; including recurrent cervical cancer) after fertility-sparing surgery. METHODS: In this nationwide, population-based, retrospective cohort study, we used data from the Netherlands Cancer Registry and the Dutch Nationwide Pathology Databank. All patients aged 18-40 years with cervical cancer of any histology who received fertility-sparing surgery (ie, large loop excision of the transformation zone, conisation, or trachelectomy) between Jan 1, 2000, and Dec 31, 2020, were included. Pathology data from diagnosis, treatment, and during follow-up were analysed. The primary and secondary outcomes were the cumulative incidence of recurrent CIN2+ and recurrence-free survival, overall and stratified by results for cytology and high-risk HPV. FINDINGS: 1548 patients were identified, of whom 1462 met the inclusion criteria. Of these included patients, 19 568 pathology reports were available. The median age at diagnosis was 31 years (IQR 30-35). After a median follow-up of 6·1 years (IQR 3·3-10·8), recurrent CIN2+ was diagnosed in 128 patients (cumulative incidence 15·0%, 95% CI 11·5-18·2), including 52 patients (cumulative incidence 5·4%, 95% CI 3·7-7·0) with recurrent cervical cancer. The overall 10-year recurrence-free survival for CIN2+ was 89·3% (95% CI 87·4-91·3). By cytology at first follow-up visit within 12 months after fertility-sparing surgery, 10-year recurrence-free survival for CIN2+ was 92·1% (90·2-94·1) in patients with normal cytology, 84·6% (77·4-92·3) in those with low-grade cytology, and 43·1% (26·4-70·2) in those with high-grade cytology. By high-risk HPV status at first follow-up visit within 12 months after surgery, 10-year recurrence-free survival for CIN2+ was 91·1% (85·3-97·3) in patients who were negative for high-risk HPV and 73·6% (58·4-92·8) in those who were positive for high-risk HPV. Cumulative incidence of recurrent CIN2+ within 6 months after any follow-up visit (6-24 months) in patients negative for high-risk HPV with normal or low-grade cytology was 0·0-0·7% and with high-grade cytology was 0·0-33·3%. Cumulative incidence of recurrence in patients positive for high-risk HPV with normal or low-grade cytology were 0·0-15·4% and with high-grade cytology were 50·0-100·0%. None of the patients who were negative for high-risk HPV without high-grade cytology, at 6 months and 12 months, developed recurrence. INTERPRETATION: Patients who are negative for high-risk HPV with normal or low-grade cytology at 6-24 months after fertility-sparing surgery, could be offered a prolonged follow-up interval of 6 months. This group comprises 80% of all patients receiving fertility-sparing surgery. An interval of 12 months seems to be safe after two consecutive negative tests for high-risk HPV with an absence of high-grade cytology, which accounts for nearly 75% of all patients who receive fertility-sparing surgery.

Quality of integrated female oncofertility care is suboptimal: A patient-reported measurement.

BACKGROUND: Clinical practice guidelines recommend to inform female cancer patients about their infertility risks due to cancer treatment. Unfortunately, it seems that guideline adherence is suboptimal. In order to improve quality of integrated female oncofertility care, a systematic assessment of current practice is necessary. METHODS: A multicenter cross-sectional survey study in which a set of systematically developed quality indicators was processed, was conducted among female cancer patients (diagnosed in 2016/2017). These indicators represented all domains in oncofertility care; risk communication, referral, counseling, and decision-making. Indicator scores were calculated, and determinants were assessed by multilevel multivariate analyses. RESULTS: One hundred twenty-one out of 344 female cancer patients participated. Eight out of 11 indicators scored below 90% adherence. Of all patients, 72.7% was informed about their infertility, 51.2% was offered a referral, with 18.8% all aspects were discussed in counseling, and 35.5% received written and/or digital information. Patient's age, strength of wish to conceive, time before cancer treatment, and type of healthcare provider significantly influenced the scores of three indicators. CONCLUSIONS: Current quality of female oncofertility care is far from optimal. Therefore, improvement is needed. To achieve this, improvement strategies that are tailored to the identified determinants and to guideline-specific barriers should be developed.

Effects of chemotherapy on ovaries of pregnant mice.

PURPOSE: It is unknown if future fertility is compromised by the administration of chemotherapy during pregnancy. The aim of this study was to identify if chemotherapy affects the maternal ovaries during pregnancy and whether these effects depend on type of chemotherapy and duration of exposure. METHODS: Pregnant 8-week-old female BL6 mice were exposed to 6 different single chemotherapeutic agents (carboplatin, cisplatin, paclitaxel, epirubicin, doxorubicin, or cyclophosphamide) or saline at gestational day (GD) 13.5. The mice were sacrificed at GD 15.5 or GD 18.5. Ovaries were assessed by histopathology and immunohistochemistry. Follicle count was determined per follicle stage and per treatment modality. RESULTS: Maternal ovarian damage was demonstrated by the presence of apoptosis and necrosis in preantral follicles. The extent of this damage depends upon type of chemotherapy and duration of exposure (2 or 5 days). After short exposure, 81% of ovaries showed histopathologic signs of damage compared to 36% after long exposure, which might suggest a transient effect. Loss of primordial follicles (PMFs) was observed after both short and long exposure, with a reduction of more than 70%. Evidence of DNA damage, as demonstrated by phospho-H2AX expression, was present in 23% (range 0-89%) of PMFs exposed to chemotherapy, but only in the short exposure group. Overall, the least damage was seen after administration of paclitaxel. CONCLUSION: Despite physiological ovarian function suppression during gestation, chemotherapy-induced damage of the ovaries occurs in pregnant mouse models, potentially affecting future fertility.

Fertility-Sparing Surgery in Gynecologic Cancer: A Systematic Review.

Fertility-sparing surgery (FSS) is increasingly being offered to women with a gynecological malignancy who wish to preserve fertility. In this systematic review, we evaluate the best evidence currently available on oncological and reproductive outcome after FSS for early stage cervical cancer, epithelial ovarian cancer, and endometrial cancer. An extensive literature search was conducted using the electronic databases Medline (OVID), Embase, and Cochrane Library to identify eligible studies published up to December 2020. In total, 153 studies were included with 7544, 3944, and 1229 patients who underwent FSS for cervical, ovarian, and endometrial cancer, respectively. We assessed the different FSS techniques that are available to preserve fertility, i.e., omitting removal of the uterine body and preserving at least one ovary. Overall, recurrence rates after FSS are reassuring and therefore, these conservative procedures seem oncologically safe in the current selection of patients with low-stage and low-grade disease. However, generalized conclusions should be made with caution due to the methodology of available studies, i.e., mostly retrospective cohort studies with a heterogeneous patient population, inducing selection bias. Moreover, about half of patients do not pursue pregnancy despite FSS and the reasons for these decisions have not yet been well studied. International collaboration will facilitate the collection of solid evidence on FSS and the related decision-making process to optimize patient selection and counseling.

Lactate point-of-care testing for acidosis: Cross-comparison of two devices with routine laboratory results.

OBJECTIVES: Lactate is a major parameter in medical decision making. During labor, it is an indicator for fetal acidosis and immediate intervention. In the Emergency Department (ED), rapid analysis of lactate/blood gas is crucial for optimal patient care. Our objectives were to cross-compare-for the first time-two point-of-care testing (POCT) lactate devices with routine laboratory results using novel tight precision targets and evaluate different lactate cut-off concentrations to predict metabolic acidosis. DESIGN AND METHODS: Blood samples from the delivery room (n=66) and from the ED (n=85) were analyzed on two POCT devices, the StatStrip-Lactate (Nova Biomedical) and the iSTAT-1 (CG4+ cassettes, Abbott), and compared to the routine laboratory analyzer (ABL-735, Radiometer). Lactate concentrations were cross-compared between these analyzers. RESULTS: The StatStrip correlated well with the ABL-735 (R=0.9737) and with the iSTAT-1 (R=0.9774) for lactate in umbilical cord blood. Lactate concentrations in ED samples measured on the iSTAT-1 and ABL-735 showed a correlation coefficient of R=0.9953. Analytical imprecision was excellent for lactate and pH, while for pO2 and pCO2 the coefficient of variation was relatively high using the iSTAT-1. CONCLUSION: Both POCT devices showed adequate analytical performance to measure lactate. The StatStrip can indicate metabolic acidosis in 1 µl blood and will be implemented at the delivery room.

Successful placement of the Essure device after a failed procedure using the Adiana system for hysteroscopic sterilisation.

This case report describes a successful hysteroscopic sterilisation using the Essure Permanent Birth Control device (Conceptus Inc., Mountain View, California, United States) after a failed procedure of the Adiana Permanent Contraception system (Hologic, Inc., Bedford, Maryland, United States). The delivery catheter of the Adiana system was able to be inserted into the left fallopian tube without difficulty and per manufacturer specifications. However, the position detection array was unable to sense four-quadrant tissue contact. The same issue occurred at the contralateral tube. Using the Essure system, the coils were able to be placed in both ostia easily and adequately. In patients in whom the Adiana system fails to occlude the fallopian tubes due to procedural, anatomic or device-related factors, the Essure procedure may be an efficient alternative.
