Gemcitabine for advanced endometrial cancer: a retrospective study of the Memorial sloan-Kettering Cancer Center experience

Gemcitabine-Associated Retinopathy With Bilateral Exudative Retinal Detachment and Elschnig's Spots

A 47-year-old woman consulted Fundación de Cirugía Ocular Jorge Zambrano for a 45-day bilateral vision decrease. Fundus examination revealed retinal edema, peripapillary cotton wool exudates, nerve fiber layer hemorrhages, Elschnig's spots, and peripheral exudative retinal detachment in both eyes. These findings were suspected to be a complication from gemcitabine, a chemotherapeutic agent that she had taken for endometrial cancer, which was discontinued owing to thrombocytopenia. One month later, her bilateral vision and posterior segment findings improved without treatment. This is the first report of gemcitabine-associated retinopathy described with the presence of bilateral exudative retinal detachment and Elschnig's spots.

Gut and Endometrial Microbiome Dysbiosis: A New Emergent Risk Factor for Endometrial Cancer

Endometrial cancer is one of the most common gynaecological malignancies worldwide. Histologically, two types of endometrial cancer with morphological and molecular differences and also therapeutic implications have been identified. Type I endometrial cancer has an endometrioid morphology and is estrogen-dependent, while Type II appears with non-endometrioid differentiation and follows an estrogen-unrelated pathway. Understanding the molecular biology and genetics of endometrial cancer is crucial for its prognosis and the development of novel therapies for its treatment. However, until now, scant attention has been paid to environmental components like the microbiome. Recently, due to emerging evidence that the uterus is not a sterile cavity, some studies have begun to investigate the composition of the endometrial microbiome and its role in endometrial cancer. In this review, we summarize the current state of this line of investigation, focusing on the relationship between gut and endometrial microbiome and inflammation, estrogen metabolism, and different endometrial cancer therapies.

Integrative bioinformatic analyses of an oncogenomic profile reveal the biology of endometrial cancer and guide drug discovery

A major challenge in personalized cancer medicine is to establish a systematic approach to translate huge oncogenomic datasets to clinical situations and facilitate drug discovery for cancers such as endometrial carcinoma. We performed a genome-wide somatic mutation-expression association study in a total of 219 endometrial cancer patients from TCGA database, by evaluating the correlation between ∼5,800 somatic mutations to ∼13,500 gene expression levels (in total, ∼78, 500, 000 pairs). A bioinformatics pipeline was devised to identify expression-associated single nucleotide variations (eSNVs) which are crucial for endometrial cancer progression and patient prognoses. We further prioritized 394 biologically risky mutational candidates which mapped to 275 gene loci and demonstrated that these genes collaborated with expression features were significantly enriched in targets of drugs approved for solid tumors, suggesting the plausibility of drug repurposing. Taken together, we integrated a fundamental endometrial cancer genomic profile into clinical circumstances, further shedding light for clinical implementation of genomic-based therapies and guidance for drug discovery.

ESMO-ESGO-ESTRO Consensus Conference on Endometrial Cancer: Diagnosis, Treatment and Follow-up

The first joint European Society for Medical Oncology (ESMO), European SocieTy for Radiotherapy & Oncology (ESTRO) and European Society of Gynaecological Oncology (ESGO) consensus conference on endometrial cancer was held on 11-13 December 2014 in Milan, Italy, and comprised a multidisciplinary panel of 40 leading experts in the management of endometrial cancer. Before the conference, the expert panel prepared three clinically-relevant questions about endometrial cancer relating to the following four areas: prevention and screening, surgery, adjuvant treatment and advanced and recurrent disease. All relevant scientific literature, as identified by the experts, was reviewed in advance. During the consensus conference, the panel developed recommendations for each specific question and a consensus was reached. Results of this consensus conference, together with a summary of evidence supporting each recommendation, are detailed in this article. All participants have approved this final article.

Outcome of recurrent uterine papillary serous carcinoma treated with platinum-based chemotherapy

OBJECTIVE

The aim of this study was to estimate the outcome and response to platinum-based chemotherapy (CT) in patients with recurrent uterine papillary serous carcinoma (UPSC).

METHODS

Patients with recurrent UPSC from 2000 to 2012 were included retrospectively. All patients received platinum-based CT for recurrent disease. Platinum-free interval was divided into less than 6 months (platinum resistant) and 6 months or longer (platinum sensitive).

RESULTS

Twenty-two patients with recurrent UPSC were included. The median age was 66.5 years. The majority of the patients initially presented with advanced-stage disease (68%). A total of 84% (18/22) received adjuvant CT; all regimens were platinum based.The overall response rate (RR) and stable disease were 50% and 36.4%. The mean duration of response and stable disease were 9.4 and 5.6 months. Among the platinum-sensitive group, the overall RR was 64.7% compared with 0% in the platinum-resistant group. Among the patients who received prior adjuvant platinum-based CT, the RR was 38.8% compared with 100% among those who did not receive adjuvant CT. When stratified by platinum-based regimen, those who received the platinum-taxane regimen had a higher RR compared with those who received the platinum-gemcitabine regimen (62.5% vs 20%) among those who received prior adjuvant platinum therapy. The median progression-free survival and overall survival for the entire cohort were 8.4 and 24.9 months, respectively. The median progression-free survival was significantly longer for platinum-sensitive disease compared with platinum-resistant disease (10.2 vs 3.3 months, respectively; P = 0.002). Similarly, the median overall survival was longer for platinum-sensitive disease compared with platinum-resistant disease (27.1 vs 13.7 months, respectively). However, this difference was not statistically significant (P = 0.15).

CONCLUSIONS

Platinum-based CT is an active regimen in recurrent UPSC even if patients received prior adjuvant platinum CT. Platinum-free interval predicts response and outcome of platinum-based CT in recurrent setting such as in ovarian cancer. Plantinum-taxane is more active than platinum-gemcitabine in recurrent UPSC.

Cytoreductive surgery with hyperthermic intraperitoneal chemotherapy for the treatment of endometrial cancer with peritoneal carcinomatosis

OBJECTIVE

To investigate the benefit of cytoreductive surgery combined with hyperthermic intraperitoneal chemotherapy (HIPEC) for the treatment of endometrial peritoneal carcinomatosis.

STUDY DESIGN

Preoperative, intraoperative and postoperative data were collected prospectively for 13 patients treated in our University hospital.

RESULTS

Of the thirteen patients treated, one patient was lost to follow up. Three patients died within the first twelve months of treatment, and two patients died at respectively 12.4 and 19.4 months after the HIPEC procedure. Seven patients are alive, four of them without recurrence, between 1.5 and 124.8 months after surgery. The Peritoneal Cancer Index (PCI) and the Completeness of Cytoreduction-Score (CC-S) are prognostic factors for survival after HIPEC treatment for peritoneal carcinomatosis of endometrial origin.

CONCLUSIONS

The significant survival time in selected patients should lead to a study of the management of peritoneal carcinomatosis of endometrial origin in a larger number of cases, and justifies a clinical trial on a larger scale.
