RESUMEN

OBJECTIVE: The Laparoscopic Approach to Cervical Cancer (LACC) trial found that minimally invasive radical hysterectomy compared to open radical hysterectomy compromised oncologic outcomes and was associated with worse progression-free survival (PFS) and overall survival (OS) in early-stage cervical carcinoma. We sought to assess oncologic outcomes at multiple centers between minimally invasive (MIS) radical hysterectomy and OPEN radical hysterectomy. METHODS: This is a multi-institutional, retrospective cohort study of patients with 2009 FIGO stage IA1 (with lymphovascular space invasion) to IB1 cervical carcinoma from 1/2007-12/2016. Patients who underwent preoperative therapy were excluded. Squamous cell carcinoma, adenocarcinoma, and adenosquamous carcinomas were included. Appropriate statistical tests were used. RESULTS: We identified 1093 cases for analysis-715 MIS (558 robotic [78%]) and 378. OPEN procedures. The OPEN cohort had more patients with tumors >2 cm, residual disease in the hysterectomy specimen, and more likely to have had adjuvant therapy. Median follow-up for the MIS and OPEN cohorts were 38.5 months (range, 0.03-149.51) and 54.98 months (range, 0.03-145.20), respectively. Three-year PFS rates were 87.9% (95% CI: 84.9-90.4%) and 89% (95% CI: 84.9-92%), respectively (P = 0.6). On multivariate analysis, the adjusted HR for recurrence/death was 0.70 (95% CI: 0.47-1.03; P = 0.07). Three-year OS rates were 95.8% (95% CI: 93.6-97.2%) and 96.6% (95% CI: 93.8-98.2%), respectively (P = 0.8). On multivariate analysis, the adjusted HR for death was 0.81 (95% CI: 0.43-1.52; P = 0.5). CONCLUSION: This multi-institutional analysis showed that an MIS compared to OPEN radical hysterectomy for cervical cancer did not appear to compromise oncologic outcomes, with similar PFS and OS.

RESUMEN

COVID-19 has caused unprecedented societal turmoil, triggering a rapid, still ongoing, transformation of healthcare provision on a global level. In this new landscape, it is highly important to acknowledge the challenges this pandemic poses on the care of the particularly vulnerable cancer patients and the subsequent psychosocial impact on them. We have outlined our clinical experience in managing patients with gastrointestinal, hematological, gynaecological, dermatological, neurological, thyroid, lung and paediatric cancers in the COVID-19 era and have reviewed the emerging literature around barriers to care of oncology patients and how this crisis affects them. Moreover, evolving treatment strategies and novel ways of addressing the needs of oncology patients in the new context of the pandemic are discussed.

RESUMEN

AIM: To investigate the prevalence of cervico-vaginal co-infection with high-risk (HR) HPV types and other sexually transmitted pathogens (STPs) in women with anogenital warts (AGWs). PATIENTS AND METHODS: In this cross-sectional study, cervico-vaginal smears of women with AGWs were examined with real-time polymerase chain reaction for the presence of HR-HPV types and common STPs. Women with recent cervical HPV infection and general population were used for comparisons. RESULTS: A total of 689 women participated in the study. Among the examined groups, higher rates of cervico-vaginal co-infection with HR-HPV types and other STPs collectively were recorded in women with AGWs (p=0.0049 and p<0.004, respectively). Within the AGWs group, cervical co-infection with HR-HPV types was detected more often in women with recurrent disease (p<0.001). CONCLUSION: The higher rates of cervico-vaginal co-infection with HR-HPV types and common STPs in women with AGWs may affect their risk for cervical carcinogenesis and the natural course of their disease.

RESUMEN

OBJECTIVE: To compare oncologic and perioperative outcomes in patients who underwent minimally invasive surgery (MIS) compared to laparotomy for newly diagnosed early-stage cervical carcinoma. METHODS: We retrospectively identified patients who underwent radical hysterectomy for stage IA1 with lymphovascular invasion (LVI), IA2, or IB1 cervical carcinoma at our institution from 1/2007-12/2017. Clinicopathologic characteristics and surgical and oncologic survival outcomes were compared using appropriate statistical testing. Multivariable Cox regression analysis was used to control for potential confounders. RESULTS: We identified 196 evaluable cases-117 MIS (106 robotic [90.6%]) and 79 laparotomy cases. Cohorts had similar age, BMI, substage, histologic subtype, clinical and pathologic tumor size, positive margins, and presence of LVI. The MIS group had more cases with no residual tumor in the hysterectomy (24.8% vs. 10.1%, P = 0.01). The laparotomy group had more cases with positive nodes (29.1% vs. 17.1%, P = 0.046) and more patients who received adjuvant therapy (53.2% vs. 33.3%, P = 0.006). Median follow-up was ~4 years. Five-year disease-free survival (DFS) rates were 87.0% in the MIS group and 86.6% in the laparotomy group (P = 0.92); 5-year disease-specific survival (DSS) rates were 96.5% and 93.9%, respectively (P = 0.93); and 5-year overall survival (OS) rates were 96.5% and 87.4%, respectively (P = 0.15). MIS was not associated with DFS, DSS, or OS on multivariable regression analysis. The rate of postoperative complications was significantly lower in the MIS cohort (11.1% vs. 20.3%; P = 0.04). CONCLUSIONS: MIS radical hysterectomy for cervical carcinoma did not confer worse oncologic outcomes in our single-center and concurrent series of patients with early-stage cervical carcinoma.

RESUMEN

Background: Human Papilloma Virus has been considered as the main cause for cervical cancer. In this study we investigated epigenetic changes and especially methylation of specific sites of HPV genome. The main goal was to correlate methylation status with histological grade as well as to determine its accuracy in predicting the disease severity by establishing optimum methylation cutoffs. Methods: In total, sections from 145 cases genotyped as HPV16 were obtained from formalin- fixed, paraffin-embedded tissue of cervical biopsies, conization or hysterectomy specimens. Highly accurate pyrosequencing of bisulfite converted DNA, was used to quantify the methylation percentages of UTR promoter, enhancer and 5' UTR, E6 CpGs 494, 502, 506 and E7 CpGs 765, 780, 790. The samples were separated in different groupings based on the histological outcome. Statistical analysis was performed by SAS 9.4 for Windows and methylation cutoffs were identified by MATLAB programming language. Results: The most important methylation sites were at the enhancer and especially UTR 7535 and 7553 sites. Specifically for CIN3+ (i.e. HSIL or SCC) discrimination, a balanced sensitivity vs. specificity (68.1%, 66.2% respectively) with positive predictive value (PPV) and negative predictive value (NPV) (66.2%, 68.2% respectively) was achieved for UTR 7535 methylation of 6.1% cutoff with overall accuracy 67.1%, while for UTR 7553 a sensitivity 60.9%, specificity 69.0%, PPV=65.6%, NPV=64.5% and overall accuracy=65.0% at threshold 10.1% was observed. Conclusion: Viral HPV16 genome was found methylated in NF-1 binding sites of UTR in cases with high grade disease. Methylation percentages of E6 and E7 CpG sites were elevated at the cancer group.

RESUMEN

OBJECTIVES: To assess outcomes after secondary surgical resection in patients with recurrent uterine leiomyosarcoma (uLMS). METHODS: We retrospectively identified all patients who had no evidence of disease after initial surgery for uLMS, who underwent surgery for a first recurrence at our institution between 1/1991 and 10/2013. We excluded patients who received any therapy for recurrence prior to secondary resection, and patients who underwent surgery soon after morcellation [of presumed benign fibroids] showed widespread disease. Overall survival (OS) was determined from time of first recurrence to death or last follow-up. RESULTS: We identified 62 patients: 29 with abdominal/pelvic recurrence only, 30 with lung recurrence only, 3 with both. Median time to first recurrence was 18 months (95% CI: 13.3-23.3): 15.8 months (95% CI: 13.0-18.6) abdominal/pelvic recurrence; 24.1 months (95% CI: 14.5-33.7) lung-only recurrence (p = 0.03). Median OS was 37.7 months (95% CI: 25.9-49.6) abdominal/pelvic recurrence; 78.1 months (95% CI: 44.8-11.4) lung recurrence (p = 0.02). Complete gross resection (CGR) was achieved in 58 cases (93%), with gross residual ≤1 cm in 2 (3.5%) and >1 cm in 2 (3.5%). Median OS based on residual disease was 54.1 months (95% CI: 24.9-83.3), 38.7 months (95% CI: NE), 1.7 months (95% CI: NE), respectively (p < 0.001). In cases with CGR, neither adjuvant radiation (N = 9), chemotherapy (N = 8) nor hormonal therapy (N = 10) was associated with improved OS. CONCLUSIONS: Secondary surgical resection of recurrent uLMS is reasonable in patients with a high probability of achieving CGR. Lung-only recurrences were associated with more favorable outcome. Following CGR, additional therapy may not offer benefit.

RESUMEN

OBJECTIVE: To explore the impact of primary debulking surgery (PDS) to minimal but gross residual disease (RD) in women with bulky stage IIIC ovarian, fallopian tube, or primary peritoneal cancer. METHODS: We retrospectively reviewed all patients with the aforementioned diagnosis who underwent PDS at our institution from 01/2001-12/2010. Those with disease of non-epithelial histology or borderline tumors were excluded. Clinicopathologic data were abstracted, and appropriate statistical tests were used. RESULTS: We identified 496 eligible patients. Median age was 62years; 91% had disease of serous histology. Patients were grouped by RD status: no gross RD, 184 (37%); RD of 1-5mm, 127 (26%); RD of 6-10mm, 54 (11%); and RD >10mm, 131 (26%). With a median follow-up of 53months, the median progression-free survivals (PFS) were: 26.7, 20.7, 16.2, and 13.6months, respectively (p<0.001). The median overall survivals (OS) were 83.4, 54.5, 43.8, and 38.9months, respectively (p<0.001). Among patients with RD following PDS, those with RD of 1-10mm had improved PFS (p<0.001) and OS (p=0.001) compared with those with RD >10mm. Patients with RD 1-10mm who received intravenous/intraperitoneal (IV/IP) chemotherapy were younger and had prolonged OS compared with those solely exposed to IV chemotherapy (p<0.001 and p=0.002, respectively). CONCLUSIONS: PDS to no gross RD was associated with the longest PFS and OS. However, cytoreduction to 1-10mm of RD was also associated with better survival outcomes compared with cytoreduction to >10mm of RD. We conclude that PDS remains an appropriate option for patients with a high likelihood of achieving RD 1-10mm, especially for younger patients who can receive IV/IP chemotherapy after PDS.

RESUMEN

BACKGROUND: γH2AX is a protein biomarker for double-stranded DNA breakage; its expression was studied in cervical squamous intraepithelial lesions and carcinomas. METHODS: Immunostaining for phospho-γH2AX was performed in sections from histologically confirmed cervical SIL and carcinomas, as well as from normal cervices used as controls. In total, 275 cases were included in the study: 112 low grade SIL (LGSIL), 99 high grade SIL (HGSIL), 24 squamous cell carcinoma (SCC), 12 adenocarcinoma and 28 cervical specimens with no essential lesions. Correlation of histological grading, high risk vs. low risk HPV virus presence, activated vs. non-activated status (by high risk HPV mRNA expression) and γH2AX expression in both basal and surface segments of the squamous epithelium was performed. RESULTS: Gradual increase of both basal and surface γH2AX expression was noted up from normal cervices to LGSIL harboring a low risk HPV type, to LGSIL harboring a high risk virus at a non-activated state (p<0.05). Thereafter, both basal and surface γH2AX expression dropped in LGSIL harboring a high risk virus at an activated state and in HGSIL. CONCLUSIONS: γH2AX could serve as a potential biomarker discriminating between LGSIL and HGSIL, as well as between LGSIL harboring high risk HPV at an activated state.

RESUMEN

BACKGROUND: Pelvic radiotherapy (RT) is a standard component of the management for patients with locally advanced rectal cancer or squamous cell carcinoma of the anus. Pelvic RT leads to permanent and irreversible ovarian failure in young women. This study aimed to determine the effectiveness of robotically assisted laparoscopic ovarian transposition (OT) before RT in women with rectal or anal cancer who wanted to preserve normal ovarian function. METHODS: The study reviewed the medical records of all patients treated at our institution from August 2009 to October 2014 who received robotically assisted laparoscopic OT for rectal or anal cancer before RT. Clinical and hormonal data were abstracted to determine ovarian function. RESULTS: The study identified 22 women with rectal (n = 20) or anal (n = 2) cancer. The median age of the women was 39 years (range 26-45 years). For one patient, OT was technically not feasible. The postoperative course was uneventful in all but one case. Follow-up data on ovarian function were unavailable for 3 patients. The median times from RT initiation to the last gynecologic or hormonal evaluation were 9 months (range 5-47 months) and 10.5 months (range 5-47 months), respectively. At the last gynecologic or hormonal follow-up visit, ovarian function was preserved in 12 (67%) of 18 evaluable patients, including 9 (90%) of 10 patients 40 years of age or younger and 3 (38%) of 8 patients older than 40 years (P = 0.07). CONCLUSIONS: Robotically assisted laparoscopic bilateral OT is safe and can lead to preservation of ovarian function in two-thirds of patients with low gastrointestinal cancer undergoing pelvic RT. It should be considered in this setting, especially for women age 40 years or younger, to avoid premature menopause and its associated sequelae.

RESUMEN

BACKGROUND: Minimally invasive surgery (MIS) is associated with decreased complication rates, length of hospital stay, and cost compared with laparotomy. Robotic-assisted surgery-a method of laparoscopy-addresses many of the limitations of standard laparoscopic instrumentation, thus leading to increased rates of MIS. We sought to assess the impact of robotics on the rates and costs of surgical approaches in morbidly obese patients with uterine cancer. METHODS: Patients who underwent primary surgery at our institution for uterine cancer from 1993 to 2012 with a BMI ≥40 mg/m(2) were identified. Surgical approaches were categorized as laparotomy (planned or converted), laparoscopic, robotic, or vaginal. We identified two time periods based on the evolving use of MIS at our institution: laparoscopic (1993-2007) and robotic (2008-2012). Direct costs were analyzed for cases performed from 2009 to 2012. RESULTS: We identified 426 eligible cases; 299 performed via laparotomy, 125 via MIS, and 2 via a vaginal approach. The rates of MIS for the laparoscopic and robotic time periods were 6 % and 57 %, respectively. The rate of MIS was 78 % in this morbidly obese cohort in 2012; 69 % were completed robotically. The median length of hospital stay was 5 days (range 2-37) for laparotomy cases and 1 day (range 0-7) for MIS cases (P < 0.001). The complication rate was 36 and 15 %, respectively (P < 0.001). The rate of wound-related complications was 27 and 6 %, respectively (P < 0.001). Laparotomy was associated with the highest cost. CONCLUSIONS: The robotic platform provides significant health and cost benefits by increasing MIS rates in this patient population.

RESUMEN

miRNAs are small noncoding RNAs that regulate gene expression at the post-transcriptional level. Since their discovery, miRNAs have been associated with every cell function including malignant transformation and metastasis. Endometrial cancer is the most common gynecologic malignancy. However, improvement should be made in interobserver agreement on histological typing and individualized therapeutic approaches. This article summarizes the role of miRNAs in endometrial cancer pathogenesis and treatment.

RESUMEN

We aim to present the first case of a pregnancy achieved by administering sildenafil (Viagra) to a woman not responding to controlled ovarian hyperstimulation (COH) with the sole use of gonadotropins. A 37-year-old woman underwent COH, as part of an intracytoplasmic sperm injection (ICSI) cycle, with the combination of r-FSH and HMG for 13 d, without evidence of follicular growth. The addition of oral sildenafil at a dose of 50 mg per day for a total of five doses improved the ovarian response and resulted in the retrieval of 10 oocytes. Three embryos were transferred to the uterine cavity resulting in a successful pregnancy and, eventually, the delivery of a healthy neonate. Conclusively, the use of sildenafil as an adjunct to COH protocols may enhance ovarian response in a woman with poor ovarian response (POR) and merits further research.

RESUMEN

The study was designed to investigate the effect of dexamethasone (DEX) on the latency period to delivery in a murine model of preterm labor. To this purpose, pregnant mice were randomly assigned in groups: the control group received water for injection (n=20), the preterm labor group was injected with lipopolysaccharide (LPS) (n=22), while the glucocorticoids group was administered DEX either 1h before (n=17) or after (n=7) lipopolysaccharide. In a first set of experiments animals were monitored to record perinatal outcomes. In another set of experiments, the remaining animals were sacrificed eight h after interventions. Fetuses were homogenized to measure tumor necrosis alpha in supernatants. Maternal splenocytes were isolated and stimulated for cytokine production. Serum of mice was incubated with donor cells from healthy pregnant and non-pregnant animals to induce apoptosis. LPS induced preterm labor but treatment or pretreatment with DEX delayed parturition exerting a favorable impact on survival of delivered fetuses. DEX inverted the increase of fetoplacental tumor necrosis alpha levels. Serum of LPS-stimulated mice induced apoptosis of splenocytes of either pregnant or non-pregnant healthy mice; this was reversed after incubation of splenocytes with serum coming from DEX pre-treated mice. The presented findings suggest that DEX administered either as pre-treatment or treatment prolonged gestation and promoted neonatal survival in a sterile murine model of preterm labor. These favorable outcomes were closely linked to alterations in both immune and apoptotic responses of animals.

RESUMEN

INTRODUCTION: The presence of an endometrioma has been proposed to affect the ovarian function in a negative way. Our aim was to present the key evidence on multiple aspects of endometriomas' management in subfertile couples scheduled for assisted reproduction technologies (ART). MATERIALS AND METHODS: A critical review of the existing literature was performed focusing on the need of endometrioma treatment prior to ART, the relevant options, the potentially participating surgeon's characteristics and the socioeconomic perspective. RESULTS: To date, we have no definitive data to suggest whether the damage to the ovaries observed in women with endometriomas may be related to the mere presence of the cyst, the surgical procedure to remove it, the combination of the two, or factors currently unknown. Moreover, there is no conclusive evidence that, for subfertile couples, removal of endometriomas increases the chance of having a baby. The uncertainty regarding the best treatment strategy and factors such as the limited number of tertiary centers for laparoscopic surgery throughout the world seems to further complicate the decision. CONCLUSIONS: Until research addresses the current "grey areas", the management of endometriomas in patients undergoing ART should be individualized and take into consideration numerous parameters.

RESUMEN

OBJECTIVE: To investigate the hCG profiles in a diverse patient group with ectopic pregnancy (EP) and to understand when they may mimic the curves of an intrauterine pregnancy (IUP) or spontaneous abortion (SAB). DESIGN: Retrospective cohort study. SETTING: Three university hospitals. PATIENT(S): One hundred seventy-nine women with symptomatic pregnancy of unknown location. INTERVENTION(S): None. MAIN OUTCOME MEASURE(S): Slope of log hCG; days and visits to final diagnosis. RESULT(S): Of women with an EP, 60% initially exhibited an increase in hCG values, with a median slope of 32% increase in 2 days; 40% of subjects initially had an hCG decrease, with the median slope calculated as a 15% decline in 2 days. In total, the hCG curves in 27% of women diagnosed with EP resembled that of a growing IUP or SAB. Of the EP hCG curves, 16% demonstrated a change in the direction of the slope of the curve. This was more common in African Americans and less evident in Hispanics. Furthermore, it was associated with more clinical visits and days until final diagnosis. CONCLUSION(S): The rate of change in serial hCG values can be used to distinguish EP from an IUP or SAB in only 73% of cases. The number of women who had a change in direction of serial hCG values was associated with race and ethnicity.

RESUMEN

INTRODUCTION: Mild ovarian stimulation has been conceived, proposed and implemented in clinical practice as a safer and cheaper alternative to conventional strategies of controlled ovarian hyperstimulation in preparation for in vitro fertilization (IVF). Our aim was to summarize the key evidence on this topic and explore its possible role as the standard treatment option for women undergoing IVF. MATERIALS AND METHODS: A short narrative review of the existing literature, with emphasis on mild ovarian stimulation clinical and cost effectiveness, as well as treatment limitations. RESULTS: Numerous studies highlight mild ovarian stimulation's favorable characteristics with respect to oocyte/embryo quality, reduced patient risk, and ease of intervention. There is, however, a need for high-quality laboratory environment. Limitations regarding poor responders, older women, or those seeking ovarian stimulation for non-infertility indications should also be considered. Finally, outcomes on the cumulative success rates and the cost effectiveness of mild ovarian stimulation remain inconclusive. CONCLUSION: Mild ovarian stimulation protocols for IVF should currently be implemented only in carefully selected populations. Further research is needed to clarify the remaining controversies in this IVF approach.

RESUMEN

OBJECTIVE: To report the first case of using assisted reproductive technologies (ART) for fertility preservation in a patient with mixed connective tissue disease (MCTD), secondary pulmonary hypertension (PH) and antiphospholipid syndrome (APS). DESIGN: Case-report and review of the literature. SETTING: Academic infertility practice and tertiary care center. PATIENT(S): A 25-year-old woman with MCTD, complicated with PH and APS, who was scheduled for gonadotoxic therapy INTERVENTION(S): Controlled ovarian hyperstimulation, egg retrieval, embryo banking. MAIN OUTCOME MEASURE(S): Successful ART cycle leading to embryo banking without worsening her underlying disease. RESULT(S): Following successful embryo cryopreservation, the patient experienced respiratory failure and other severe complications, resulting in a prolonged hospital stay. CONCLUSION(S): Controlled ovarian hyperstimulation for embryo banking in women with MCTD, PH and APS may pose a risk for potentially catastrophic complications. A multidisciplinary approach to these patients is necessary to optimize the outcomes of such procedures. More data are needed regarding the safety of fertility preservation technologies in patients with complex medical diseases.

RESUMEN

AIM: Epithelial cadherin (E-cadherin), a transmembrane glycoprotein involved in calcium-dependent homophilic cell-cell adhesion, is expressed aberrantly during cervical carcinogenesis. E-cadherin expression and putatively implicated predictors in healthy women remain a rather under-investigated area. The objective of this study is to evaluate the possible associations between E-cadherin expression and reproductive/lifestyle factors in cervical epithelial cells from postmenopausal women. METHODS: A total of 105 healthy postmenopausal women (aged 45-68 years old) attending a university menopause clinic were enrolled in this cross-sectional study. Pap smears were derived and E-cadherin immunostaining was evaluated in squamous, glandular and squamous metaplastic cells, using a semi-quantitative method (rating scale: 0-3). Reproductive and lifestyle factors were obtained from patients' chart review. RESULTS: In squamous cells, women with a history of 0-1 deliveries presented with a higher score vs women with 2-4 deliveries (P = 0.003). Social drinkers and women drinking alcohol daily exhibited a higher E-cadherin immunostaining score in squamous cells vs non-drinkers (0.96 +/- 0.72 vs 0.56 +/- 0.65, P = 0.004). A higher dietary calcium intake was marginally correlated with a lower staining score in squamous cells (0.94 +/- 0.78 for low, 0.71 +/- 0.70 for average, 0.45 +/- 0.52 for high consumption, P = 0.073). CONCLUSIONS: E-cadherin expression seems to be associated with reproductive history and lifestyle habits in squamous cervical cells from healthy postmenopausal women. E-cadherin might participate in the molecular mechanisms underlying the role of parity as a risk factor for cervical cancer.
