RESUMO

OBJECTIVES: The majority of hospital readmissions are unexpected and considered adverse events. The goal of this study was to examine the factors associated with unplanned readmission after surgery for vulvar cancer. METHODS: Patient demographic, treatment, and discharge factors were collected on 363 patients with squamous cell carcinoma in situ or invasive cancer who underwent vulvectomy at our institution between January 2001 and June 2014. Clinical variables were correlated using χ2 test and Student's t-test as appropriate for univariate analysis. Multivariate analysis was then performed. RESULTS: Of 363 eligible patients, 35.6% had in situ disease and 64.5% had invasive disease. Radical vulvectomy was performed in 39.1% and 23.4% underwent lymph node assessment. Seventeen patients (4.7%) were readmitted within 30days, with length of stay ranging 2 to 37days and 35% of these patients required a re-operation. On univariate analyses comorbidities, radical vulvectomy, nodal assessment, initial length of stay, and discharge to a post acute care facility (PACF) were associated with hospital readmission. On multivariate analysis, only discharge to a PACF was significantly associated with readmission (OR 6.30, CI 1.12-35.53, P=0.04). Of those who were readmitted within 30days, 29.4% had been at a PACF whereas only 6.6% of the no readmission group had been discharged to PACF (P=0.003). CONCLUSIONS: Readmission affected 4.7% of our population, and was associated with lengthy hospitalization and reoperation. After controlling for patient comorbidities and surgical radicality, multivariate analysis suggested that discharge to a PACF was significantly associated with risk of readmission.

RESUMO

OBJECTIVE: To examine changes over time in survival and treatment for women diagnosed with vulvar squamous cell carcinoma included in the Surveillance, Epidemiology, and End Results (SEER) Program. DESIGN: Retrospective analysis. SETTING: USA, data obtained from the SEER Program for 1988-2009. POPULATION: Women with vulvar squamous cell carcinoma. METHODS: Women were stratified by age: <50, 50-64, 65-79, and ≥80 years. Differences in survival and treatment patterns were analysed between age groups. Multivariate logistic regression models were constructed to examine treatment patterns. Kaplan-Meier and Cox proportional hazards survival methods were used to assess survival. MAIN OUTCOME MEASURES: Vital status from the date of diagnosis until death, censoring or last follow-up. RESULTS: The final study group consisted of 8553 women, 1806 (21.12%) <50 years, 2141 (25.03%) 50-64 years, 2585 (30.22%) 65-79 years, and 2021 (23.63%) >80 years old. After adjusting for patient and tumour characteristics, older women were less likely to have surgery and more likely to receive radiotherapy. Compared with women under 50 years, women 50-64 had a two-fold higher risk of death (HR 1.91, 95% CI 1.55-2.34); those 65-79 years had a four-fold higher risk of death (HR 4.01, 95% CI 3.32-4.82), and those ≥80 years had a seven-fold higher risk of death (HR 6.98, 95% CI 5.77-8.46). These trends stayed relatively constant over the time periods studied. CONCLUSIONS: Women over 50 years are at a higher risk of vulvar cancer-specific mortality, which increases with age. These trends stayed relatively constant over the time periods studied.

RESUMO

Ovarian cancer survival rates have stagnated in the last 20 years despite the development of novel chemotherapeutic agents. Modulators of gene expression, such as histone deacetylase (HDAC) inhibitors, are among the new agents being used in clinical trials. Predictors of sensitivity to chemotherapy have remained elusive. In this study, we show that the expression of the transcriptional corepressor C-terminal binding protein-2 (CtBP2) is elevated in human ovarian tumors. Downregulation of CtBP2 expression in ovarian cancer cell lines using short-hairpin RNA strategy suppressed the growth rate and migration of the resultant cancer cells. The knockdown cell lines also showed upregulation of HDAC activity and increased sensitivity to selected HDAC inhibitors. Conversely, forced expression of wild-type CtBP2 in the knockdown cell lines reversed HDAC activity and partially rescued cellular sensitivity to the HDAC inhibitors. We propose that CtBP2 is an ovarian cancer oncogene that regulates gene expression program by modulating HDAC activity. CtBP2 expression may be a surrogate indicator of cellular sensitivity to HDAC inhibitors.

RESUMO

OBJECTIVE: The objective of this study was to compare the efficacy of two multi-agent chemotherapeutic regiments that were previously used at the Institution for treatment of advanced and recurrent endometrial cancer. METHODS: A retrospective review of patients with Stage III, IV, and recurrent endometrial cancer who received adjuvant chemotherapy at Roswell Park Cancer Institute over a period of 21 years. Two patient groups were defined based on treatment received: cisplatin, adriamycin, and VP-16 with or without megace (PAV-M), or carboplatin and paclitaxel (CT). RESULTS: Forty-two patients with advanced or recurrent endometrial cancer were included in this review based on regimen received. Median duration of follow up was 55 months. Treatment with PAV-M resulted in more dose modifications compared to CT group (42% vs 11%, respectively). There were no significant differences in disease-free survival or overall survival. CONCLUSIONS: PAV/PAV-M is active in patients with advanced or recurrent endometrial cancer. However, toxicity associated with this triplet regimen may limit clinical use.

RESUMO

OBJECTIVE: To determine the outcomes in patients with Stage I uterine clear cell carcinoma (UCCC) treated with and without adjuvant therapy, and to compare the outcomes in these patients to that of matched controls, patients with Stage I, grade 3, endometrioid adenocarcinoma of the endometrium (EC). METHODS: Patients with FIGO Stage I UCCC who underwent comprehensive surgical staging between January 1996 and January 2007 were identified. Cases (UCCC) were matched by age, stage, adjuvant therapy, and year of diagnosis to controls consisting of patients with grade 3 EC. Recurrence and survival were analyzed using the Kaplan-Meier method. RESULTS: 25 patients with Stage I UCCC were identified of whom 13 (52%) received no adjuvant therapy and 12 (48%) received adjuvant radiation therapy (XRT). The 5-year disease-free survival and overall survival rates for the observation and the XRT groups were 78% and 75%, (p = 0.7) and 85% and 82% (p = 0.1), respectively. When compared to controls, the 5-year disease-free survival rates and overall survival rates of patients with Stage I UCCC were not significantly different, 77% vs 75% (p = 0.8) and 84% vs 88% (p = 0.5), respectively. CONCLUSIONS: In patients with Stage I UCCC tumors there was no clear benefit to adjuvant radiation given the absence of improvement in recurrence risk or any survival benefit. These data question the benefit of radiation therapy in UCCC patients with disease confined to the uterus.

RESUMO

OBJECTIVE: To determine whether the presence of bowel obstruction at the time of initial presentation has any prognostic significance in these women. DESIGN: Retrospective cohort study. SETTING: Dedicated gynaecological oncology service of a large tertiary institution. POPULATION: Women who had a bowel obstruction as part of their initial presentation of ovarian cancer were identified between 1995 and 2007. Each woman was matched with four control women (with disease but no obstruction). METHODS: Women with disease were compared with controls to determine the impact, if any, of bowel obstruction at presentation. Several prognostic variables including bowel obstruction were also evaluated in a Cox proportional hazard model. MAIN OUTCOME MEASURES: Progression-free survival (PFS) and overall survival (OS). RESULTS: Forty-eight women with disease and 192 controls were identified during the study period. The median follow-up period was 19 months among women with disease versus 20 months in controls. No differences were seen in demographics and clinical characteristics of the women. Optimal cytoreduction rate was similar between the two groups (75% versus 78%, P = 0.7). Patients with bowel obstruction had a shorter PFS and OS compared with controls [19 months versus 21 months (P = 0.01) and 22 versus 35 months (P = 0.008)], respectively. Bowel obstruction at presentation was an independent prognostic variable with a hazard ratio of 1.5 (P = 0.009). Other prognostic variables were age, stage and extent of surgical cytoreduction. CONCLUSIONS: Bowel obstruction at the time of initial presentation is an adverse prognostic factor in women with ovarian cancer.

RESUMO

Ovarian clear cell adenocarcinoma (OCCA) is a unique biological subtype of epithelial ovarian cancer, with a similar gene profile to renal cell carcinoma (RCC). Sunitinib is a vascular endothelial growth factor receptor tyrosine kinase inhibitor with proven antitumor activity in RCC and a rational biological option for treatment of OCCA. A 60-year-old woman presented with recurrent and refractory stage IA OCCA, after 9 years of remission. Sunitinib was initiated as fifth-line chemotherapy, associated with cystic degeneration of liver metastasis and a short downward trend in her CA125 level. Recurrent and refractory OCCA may respond to Sunitinib. Clinical trials are needed to objectively confirm these findings, as benefit may be limited in patients with extensively pretreated tumors.
