Use of Abdominal Radical Trachelectomy to Treat Cervical Cancer Greater Than 2 cm in Diameter
ObjectiveInvasive cervical cancer is one of the most common cancers, with 500,000 new cases diagnosed annually. Fertility preservation has become an important component of the overall quality of life of many cancer survivors. Expert opinion has suggested that fertility-sparing surgery should be limited to those patients diagnosed with cervical cancer less than 2 cm in diameter. Our objective was to report our abdominal radical trachelectomy (ART) experience in the opposite group of patients—those with a cervical cancer more than 2 cm in diameter.MethodsBetween 1999 and 2006, a total of 45 patients with cervical carcinoma at International Federation of Gynecology and Obstetrics stage IB1-IB2 measuring more than 2 cm in diameter underwent fertility-sparing ART and pelvic lymphadenectomy at the 3 institutions where the authors are based (Budapest, Hungary; London, United Kingdom; New York, United States). They were followed up for more than 5 years.ResultsFor 69% of patients (n = 31), completed ART was considered to have been curative, and no adjuvant treatment was advised. Of those patients, 93.5% (n = 29) were alive at the time of follow-up. Thirty-one percent of patients (n = 14) underwent immediate completion of radical hysterectomy. Three of 8 patients who wished to fall pregnant delivered healthy neonates.ConclusionsThe 5-year survival rate (93.5%) for this case series is equal (or better) to rates reported in the literature for patient treated with radical hysterectomy. Our survival data seem to support the hypothesis that ART is a safe treatment option for patients with invasive cervical cancer lesions of more than 2 cm.

Relationship between Polycyclic Aromatic Hydrocarbon-DNA Adducts, Environmental Tobacco Smoke, and Child Development in the World Trade Center Cohort
Background: Polycyclic aromatic hydrocarbons (PAHs), including benzo[a]pyrene (BaP), are air pollutants released by the World Trade Center (WTC) fires and urban combustion sources. BaP-DNA adducts provide a measure of PAH-specific genetic damage, which has been associated with increased risk of adverse birth outcomes and cancer. We previously reported that levels of BaP-DNA adducts in maternal and umbilical cord blood obtained at delivery were elevated among subjects who had resided within 1 mile of the WTC site during the month after 9/11; and that elevated blood adducts in combination with in utero exposure to environmental tobacco smoke (ETS) were significantly associated with decreased fetal growth. Objective: Our aim was to assess possible effects of prenatal exposure to WTC pollutants on child development. Methods: After 11 September 2001, we enrolled a cohort of nonsmoking pregnant women who delivered at three lower Manhattan hospitals. We have followed a subset of children through their third birthdays and measured cognitive and motor development using the Bayley-II Scales of Child Development (BSID-II). Results: In multivariate analyses, we found a significant interaction between cord blood adducts and in utero exposure to ETS on mental development index score at 3 years of age (p = 0.02, n = 98) whereas neither adducts nor ETS alone was a significant predictor of (BSID-II) cognitive development. Conclusion: Although limited by small numbers, these results suggest that exposure to elevated levels of PAHs in conjunction with prenatal ETS exposure may have contributed to a modest reduction in cognitive development among cohort children.

A first-in-human study of the novel metabolism-based anti-cancer agent SM-88 in subjects with advanced metastatic cancer
SummaryPurpose SM-88 (D,L-alpha-metyrosine; racemetyrosine) is a novel anti-cancer agent, used with melanin, phenytoin, and sirolimus (SMK Therapy). This pilot first-in-human study characterized the safety, tolerability, and efficacy of SMK Therapy in subjects with advanced metastatic cancer. Methods All subjects (n = 30) received SMK Therapy for an initial 6 week Cycle (5 days on, 2 off per week) and continued if well tolerated. Safety signals, clinical response, overall survival, progression free survival (PFS), and quality of life changes were assessed. Results The most common drug related adverse events were hyperpigmentation and rash. All drug related adverse events were mild to moderate in intensity. Following treatment with SMK Therapy, 4 subjects achieved complete response, 6 partial response, and 17 stable disease according to Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 (total clinical benefit 90%). Responses were observed within 6 weeks, and continued to improve, with 3 complete and 3 partial responders achieving best response after at least 3.2 months. Durable stable disease was observed, lasting a median duration of 11 months (range 1–31 months). Median overall survival for all subjects was 29.8 months, and median PFS was 13 months. Following 6 weeks of treatment, most (83.3%) subjects showed an improvement in Eastern Cooperative Oncology Group (ECOG) score and an improvement in the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ 30) global health status (baseline 61.2 ± 25.0; end of Cycle 1 80.7 ± 14.7; n = 29; p < 0.001). Conclusions The results of this study support continued development of SM-88.

Is There a Role for Transplantation in Gynecologic Oncology?: Autotransplantation and Other Lessons
ABSTRACTWe describe an exciting and novel surgical option, which may be used to treat formerly unresectable masses. This process is commonly referred to as autotransplantation (AuTn), and it combines the advances in transplant medicine and applies them to surgical oncology. The idea behind AuTn is the removal of the cancerous organ(s) to allow complete anatomic resection of the tumor mass, with consequent anastomotic reimplantation or AuTn of the now macroscopically tumor-free organ back into the patient. Autotransplantation has been used to remove large fibromatosis and desmoid tumors as well as malignant tumors. Our belief is that using lessons learned from the field of transplantation, AuTn can be applied in gynecologic oncology.

Phase II trial of SM-88, a cancer metabolism based therapy, in non-metastatic biochemical recurrent prostate cancer
SummaryBackground Androgen deprivation therapy (ADT) is a standard treatment for high-risk biochemically-recurrent, non-metastatic prostate cancer (BRPC) but is not curative and associated with toxicity. Racemetyrosine (SM-88) is an amino-acid analogue used with methoxsalen, phenytoin, and sirolimus (MPS) to enhance SM-88 activity. Method A phase 1b/2, open-label trial in BRPC and rising PSA. Patients were given daily SM-88 (230 mg BID), methoxsalen (10 mg), phenytoin (50 mg), and sirolimus (0.5 mg)). Outcome measures included changes in PSA, circulating tumor cells (CTCs) and imaging. Results 34 subjects were screened, 23 treated and 21 remained on study for ≥12 weeks. The median PSA was 6.4 ng/ml (range 1.7–80.1); doubling-time 6.2 months (range 1.4–36.6) and baseline testosterone 319.1 ng/ml (range 2.5–913.7). Median duration of therapy was 6.5 months (2.6–14.0). CTCs (median 48.5 cells/4 ml (range 15–268) at baseline) decreased a median of 65.3% in 18 of 19 patients. For patients who achieved an absolute CTC nadir count of <10 cells/4 ml (n = 10), disease control was 100% i.e. no metastases or PSA progression, while on trial (p = 0.005). PSA fell by ≥50% in 4.3% (1 subject). No patients developed metastatic disease while on treatment (metastases free survival =100%). There were no treatment-related adverse events (AEs) and quality of life was unchanged from baseline on the EORTC QLQ-C30 and QLQ-PR25. Testosterone levels rose slightly on SM-88 and were unrelated to efficacy or toxicity. Conclusions Use of SM-88 was associated with disease control while maintaining QOL. SM-88 may delay the need for ADT and the associated hormonal side effects. Larger trials are planned.Trial registration number, date of registration - NCT02796898, June 13, 2016

Psychological Issues Associated With Absolute Uterine Factor Infertility and Attitudes of Patients Toward Uterine Transplantation
Context:
Uterine transplantation (UTx).
Objective:
To explore patients’ knowledge of and attitudes toward UTx before and after a short educational intervention via a video and question and answer (Q&A) session.
Design:
Large, in-depth survey investigating patients’ motivations, aims, and beliefs on UTx.
Setting:
Imperial College London.
Participants:
Women diagnosed with absolute uterine factor infertility (AUFI) who were seeking information on UTx and had already volunteered to participate in the study.
Intervention:
A semistructured interview involving a brief baseline questionnaire before a Q&A session and a 20-minute video exploring the main risks and benefits for UTx.
Main outcome measures:
Attitudes of self-referred patients with AUFI toward UTx before and after education focusing on UTx. Rank order of importance of key UTx-related issues.
Results:
Forty women were interviewed. Following the video presentation and Q&A session, 97.5% (n = 39) would undergo UTx ahead of surrogacy and adoption in full knowledge that the latter 2 options would be ultimately safer for their own well-being and the fact that the graft could fail even prior to conception. All felt that UTx should take place, and 92.5% saw UTx as achievable.
Conclusion:
The study demonstrates a keen interest in UTx, partly because other options seem difficult to access. It is worth noting that people appear to be distancing themselves from the risk. This requires careful assessment in any clinical program. This study is the first to demonstrate a qualitative relationship between patients with AUFI and their curiosity and desire for UTx. It paves the way for forming the introduction into the psychological assessment of a potential patient.

Relationships among Polycyclic Aromatic Hydrocarbon-DNA Adducts, Proximity to the World Trade Center, and Effects on Fetal Growth
Polycyclic aromatic hydrocarbons (PAHs) are toxic pollutants released by the World Trade Center (WTC) fires and various urban combustion sources. Benzo[a]pyrene (BaP) is a representative member of the class of PAHs. PHA-DNA adducts, or BaP-DNA adducts as their proxy, provide a measure of chemical-specific genetic damage that has been associated with increased risk of adverse birth outcomes and cancer. To learn whether PAHs from the WTC disaster increased levels of genetic damage in pregnant women and their newborns, we analyzed BaP-DNA adducts in maternal (n = 170) and umbilical cord blood (n = 203) obtained at delivery from nonsmoking women who were pregnant on 11 September 2001 and were enrolled at delivery at three downtown Manhattan hospitals. The mean adduct levels in cord and maternal blood were highest among newborns and mothers who resided within 1 mi of the WTC site during the month after 11 September, intermediate among those who worked but did not live within this area, and lowest in those who neither worked nor lived within 1 mi (reference group). Among newborns of mothers living within 1 mi of the WTC site during this period, levels of cord blood adducts were inversely correlated with linear distance from the WTC site (p = 0.02). To learn whether PAHs from the WTC disaster may have affected birth outcomes, we analyzed the relationship between these outcomes and DNA adducts in umbilical cord blood, excluding preterm births to reduce variability. There were no independent fetal growth effects of either PAH-DNA adducts or environmental tobacco smoke (ETS), but adducts in combination with in utero exposure to ETS were associated with decreased fetal growth. Specifically, a doubling of adducts among ETS-exposed subjects corresponded to an estimated average 276-g (8%) reduction in birth weight (p = 0.03) and a 1.3-cm (3%) reduction in head circumference (p = 0.04). The findings suggest that exposure to elevated levels of PAHs, indicated by PAH-DNA adducts in cord blood, may have contributed to reduced fetal growth in women exposed to the WTC event.
