RESUMEN
OBJECTIVE: We studied cis-women with uterine cancer presenting to the two Public Hospitals in Queens, New York from 2006 to 2015 to examine the relationship between nativity (birthplace) and survival. METHODS: A retrospective review of tumor registries identified women diagnosed with uterine cancer between January 1, 2006, and December 31, 2015. Data from 259 women were available for this analysis. RESULTS: Most women were born outside the United States (US) (76% versus 24%). The majority of US-born women were black (68%). Seventy-seven women (30%) were born in Latin America, 76 in the Caribbean Islands (29%) and 44 in Asia/South Asia (17%). Most women presented with stage I/II disease (70%) and endometrioid/mucinous histology (68%) with no significant differences observed among nativity groups. Kaplan-Meier estimated survival curves stratified by birthplace demonstrated significant differences in survival distributions among the groups using the log-rank test (P < 0.0001). The most favorable survival curves were observed among all foreign-born women, whereas the least favorable survival was demonstrated in US-born women. Time to death was analyzed using the Cox proportional hazards model. Adjusting for age of diagnosis, insurance status, stage, and treatment modality, Latin American and Asia/South Asia birthplace was significantly associated with increased survival time. CONCLUSION: An immigrant health paradox was defined for foreign-born Latin American and Asian/South Asian women presenting to the two Public Hospitals of Queens, New York, as women born in these geographic regions were less likely to die at any given time compared to those born in the United States.

Although the progressive histologic steps leading to endometrial cancer (EndoCA), the most common female reproductive tract malignancy, from endometrial hyperplasia are well-established, the molecular changes accompanying this malignant transformation in a single patient have never been described. We had the unique opportunity to investigate the paired histologic and molecular features associated with the 12-yr development of EndoCA in a postmenopausal female who could not undergo hysterectomy and instead underwent progesterone treatment. Using a specially designed 58-gene next-generation sequencing panel, we analyzed a total of 10 sequential biopsy samples collected over this time frame. A total of eight pathogenic/likely pathogenic mutations in seven genes, APC, ARID1A, CTNNB1, CDKN2A, KRAS, PTEN, and TP53, were identified. A PTEN nonsense mutation p.W111* was present in all samples analyzed except histologically normal endometrium. Apart from this PTEN mutation, the only other recurrent mutation was KRAS G12D, which was present in six biopsy samplings, including histologically normal tissue obtained at the patient's first visit but not detectable in the cancer. The PTEN p.W111* mutant allele fractions were lowest in benign, inactive endometrial glands (0.7%), highest in adenocarcinoma (36.9%), and, notably, were always markedly reduced following progesterone treatment. To our knowledge, this report provides the first molecular characterization of EndoCA development in a single patient. A single PTEN mutation was present throughout the 12 years of cancer development. Importantly, and with potential significance toward medical and nonsurgical management of EndoCA, progesterone treatments were consistently noted to markedly decrease PTEN mutant allele fractions to precancerous levels.

Epithelial ovarian cancer (OvCa) is the most lethal female reproductive tract malignancy. A major clinical hurdle in patient management and treatment is that when using current surveillance technologies 80% of patients will be clinically diagnosed as having had a complete clinical response to primary therapy. In fact, the majority of women nonetheless develop disease recurrence within 18 mo. Thus, without more accurate surveillance protocols, the diagnostic question regarding OvCa recurrence remains framed as "when" rather than "if." With this background, we describe the case of a 61-yr-old female who presented with a 3-mo history of unexplained whole-body rash, which unexpectedly led to a diagnosis of and her treatment for OvCa. The rash resolved immediately following debulking surgery. Nearly 1 yr later, however, the rash reappeared, prompting the prospect of tumor recurrence and requirement for additional chemotherapy. To investigate this possibility, we undertook a genomics-based tumor surveillance approach using a targeted 56-gene NGS panel and biobanked tumor samples to develop personalized ctDNA biomarkers. Although tumor-specific TP53 and PTEN mutations were detectable in all originally collected tumor samples, pelvic washes, and blood samples, they were not detectable in any biosample collected beyond the first month of treatment. No additional chemotherapy was given. The rash spontaneously resolved. Now, 2 yr beyond the patient's original surgery, and in the face of continued negative ctDNA findings, the patient remains with no evidence of disease. As this single case report suggests, we believe for the first time that ctDNA can provide an additional layer of information to avoid overtreatment.

OBJECTIVE: The objective of this study was to evaluate the safety and efficacy of laparoscopic assessment to determine the likelihood of achieving optimal cytoreduction (OC) in patients undergoing primary debulking surgery (PDS) for ovarian cancer. METHODS: All patients who underwent diagnostic laparoscopy and PDS at our institution from January 2008 to December 2013 were identified. We determined the likelihood of achieving optimal cytoreduction by laparoscopic assessment based on tumor site, pattern of spread, and disease burden. Sensitivity was defined as the number of patients who achieved optimal cytoreduction after laparoscopic assessment divided by the number of patients with disease deemed resectable by laparoscopy. RESULTS: We identified 55 patients during study period. Twenty-one of the 55 patients (38%) were early stage disease. Six (10.9%) patients had disease deemed unresectable and 49 (89.1%) had disease deemed resectable at the time of laparoscopy. OC was achieved in 48 of 49 (97.9%) patients. The sensitivity of laparoscopy in predicting OC was 98% (95% confidence interval, 89.3%-99.9%). The operation was completed laparoscopically in 23 of 49 patients (47%); in 26 of 49 (53%), PDS was performed by laparotomy. There were no port site metastases reported. The rate of postoperative complications was 16%. With a median follow-up of 30 months, the median overall survival was not reached and the 75th percentile for overall survival was 37 months. CONCLUSIONS: Laparoscopy was shown to have a high sensitivity in predicting OC and is a feasible tool in triaging patients with ovarian cancer. Laparoscopy is not associated with adverse surgical outcomes.
