Application of a Malecot drain in the management of a vaginal cuff dehiscence: A case report and review of the literature.

Background: Vaginal cuff dehiscence (VCD) in the setting of acute infection is an uncommon but serious complication of total hysterectomy without clear guidelines for management. There is a need for further documentation of best practices around treatment, particularly when it comes to surgical drain utilization and placement. Case description: We present a case of a 68-year-old with primary peritoneal carcinoma who underwent a robot-assisted total laparoscopic hysterectomy as part of an interval debulking surgery and had a VCD. The cuff was repaired vaginally in the operating room with placement of a Malecot catheter for pelvic abscess drainage. Discussion: The literature is sparse in regard to clear guidelines for management of VCD. Surgical and expectant management approaches are dependent on patient stability, surgical experience, local practice norms, and evidence of intra-abdominal injury. Interventional radiology has become a primary source of drain placement in management of VCD and vaginal cuff abscess. Malecot drains are a low cost, and effective intervention for such management and an important resource for the gynecologic surgeon.

Fractured and delayed: A qualitative analysis of disruptions in care for gynecologic malignancies during incarceration.

OBJECTIVE: Women are experiencing growing rates of incarceration at twice the pace of that for men. Additionally, one-third will be older than 55 years of age by the end of the decade. Women who are incarcerated experience a higher prevalence of gynecologic malignancies and present with higher stage disease, which may be contributing to the greater mortality from cancer than the age-adjusted US population. Limited access to guideline-recommended screening and prevention and resource limitations across correctional facilities may result in gynecologic cancer disparities. Reasons for delayed gynecologic cancer care in prisons remain underexplored. Therefore, we sought to identify contributors to delayed gynecologic cancer care among women experiencing incarceration. METHODS: Women at a single tertiary center in the Southeastern U.S. who were incarcerated and were diagnosed with a gynecologic cancer during 2014-2021 were identified in the electronic medical record. Note text was extracted and contributors to delay were identified and categorized using the RADaR method. Descriptive statistics were used to assess quantitative data. RESULTS: 14 patients were identified with a total of 14,879 text excerpts. Data reduction was performed to identify excerpts that were relevant to the central research question resulting in 175 relevant note excerpts. Delays prior to the tertiary care visit included patient and institutional contributors. Delays during transition from the tertiary center to prison included discharge planning and loss to follow-up during/after incarceration. Transportation, authorization, and restraints were concrete contributors. Abstract contributors included communication, and the patient's emotional experience. CONCLUSIONS: We identify myriad contributors to delayed or fractured gynecologic cancer care in women experiencing incarceration. The impact of these issues warrants further study and intervention to improve care.

Radiation Therapy for Endometrial Cancer: An American Society for Radiation Oncology Clinical Practice Guideline.

PURPOSE: With the results of several recently published clinical trials, this guideline informs on the use of adjuvant radiation therapy (RT) and systemic therapy in the treatment of endometrial cancer. Updated evidence-based recommendations provide indications for adjuvant RT and the associated techniques, the utilization and sequencing of adjuvant systemic therapies, and the effect of surgical staging techniques and molecular tumor profiling. METHODS: The American Society for Radiation Oncology convened a multidisciplinary task force to address 6 key questions that focused on the adjuvant management of patients with endometrial cancer. The key questions emphasized the (1) indications for adjuvant RT, (2) RT techniques, target volumes, dose fractionation, and treatment planning aims, (3) indications for systemic therapy, (4) sequencing of systemic therapy with RT, (5) effect of lymph node assessment on utilization of adjuvant therapy, and (6) effect of molecular tumor profiling on utilization of adjuvant therapy. Recommendations were based on a systematic literature review and created using a predefined consensus-building methodology and system for quality of evidence grading and strength of recommendation. RESULTS: The task force recommends RT (either vaginal brachytherapy or external beam RT) be given based on the patient's clinical-pathologic risk factors to reduce risk of vaginal and/or pelvic recurrence. When external beam RT is delivered, intensity modulated RT with daily image guided RT is recommended to reduce acute and late toxicity. Chemotherapy is recommended for patients with International Federation of Gynecology and Obstetrics (FIGO) stage I to II with high-risk histologies and those with FIGO stage III to IVA with any histology. When sequencing chemotherapy and RT, there is no prospective data to support an optimal sequence. Sentinel lymph node mapping is recommended over pelvic lymphadenectomy for surgical nodal staging. Data on sentinel lymph node pathologic ultrastaging status supports that patients with isolated tumor cells be treated as node negative and adjuvant therapy based on uterine risk factors and patients with micrometastases be treated as node positive. The available data on molecular characterization of endometrial cancer are compelling and should be increasingly considered when making recommendations for adjuvant therapy. CONCLUSIONS: These recommendations guide evidence-based best clinical practices on the use of adjuvant therapy for endometrial cancer.

Clinical calculator redefines prognosis for high-risk early-stage ovarian cancers and potential to guide treatment in the adjuvant setting.

OBJECTIVE: To determine the utility of a clinical calculator to redefine prognosis and need for chemotherapy among patients with early-stage high-risk epithelial ovarian cancer. METHODS: Data were abstracted for stage I-II, high-risk ovarian cancer from the National Cancer Database from years 2005 to 2015. Based on demographic, pathologic, surgical, and laboratory characteristics, a clinical score was developed using Cox regression. Propensity score weighting was used to adjust for differences between patients who did and did not receive chemotherapy. RESULTS: Of 8188 patients with early-stage high-risk ovarian cancer, 6915 (84%) did and 1273 (16%) did not receive chemotherapy. A clinical calculator was created utilizing age, stage, histology, grade, tumor size, number of pelvic and paraaortic lymph nodes examined, the presence of malignant ascites, and CA125. The calculator divided patients into low, moderate, and high-risk groups with 5-year OS (overall survival) of 92%, 82%, and 66%, and 10-year OS of 85%, 67%, and 44%, respectively. Chemotherapy improved 5-year OS and 10-year OS in the high-risk group (56% to 73%; p < 0.001, 34% to 48%; p < 0.001). The moderate risk group had improved 5-year OS (80% to 85%; p = 0.01) but not 10-year OS (66% to 66%; p = 0.13). Chemotherapy did not improve 5-year or 10-year OS in low-risk patients (93% to 92%, p = 1.0, 86% to 84%, p = 0.99). CONCLUSIONS: The prognosis among high-risk early-stage ovarian cancer patients is heterogeneous. This calculator may aid in patient-centered counseling regarding potential treatment benefits.

A prospective randomized trial of standard versus multimedia-supplemented counseling in patients undergoing endometrial cancer staging surgery.

OBJECTIVES: A patient's understanding of surgery is often limited, especially in the setting of complex oncologic procedures. The use of supplemental materials can improve patients' knowledge of their procedure and satisfaction with decision making. We sought to determine if a multimedia-supplemented approach in patients undergoing robotic endometrial cancer staging improves satisfaction with preoperative counseling. Secondary objectives were patient comprehension, physician satisfaction, and visit length. METHODS: From 2018 to 2019, patients were randomized to standard physician education (SPE) or multimedia-based education (MBE), which included watching two novel videos followed by focused physician counseling. Basic demographic information was collected. Patient satisfaction was assessed using the Client Satisfaction Questionnaire-8 (CSQ-8, a validated satisfaction survey, scored 8-32) and a global satisfaction score (GGS, 10-point scale). Physician satisfaction was assessed using a GGS. Comprehension was assessed with a study-specific 9-question survey at three time points. t-tests and linear mixed models were used to compare groups. RESULTS: Of the 75 patients included in the analysis, the majority were white (70%), 50-70 years old (72%), and had at least some college education (74%). The MBE group reported higher satisfaction on the CSQ-8 (31.69 vs 30.69, p < 0.01) and global satisfaction score (9.95 vs 9.74, p = 0.04). There was no difference in comprehension scores over time (p = 0.84) or between groups (p = 0.23). Visit lengths were significantly longer in the MBE group (90.36 vs 80.46 min, p = 0.04). CONCLUSIONS: Patients had high satisfaction and comprehension with both SPE and MBE. Multimedia education may be implemented in preoperative counseling based on provider preference and consideration should be made for further study of satisfaction, both patient and physician, and visit length after the initial implementation period.

Endometrial cancer: A society of gynecologic oncology evidence-based review and recommendations, part II.

In 2014, the Society of Gynecologic Oncology's Clinical Practice Committee published a clinical update reviewing the treatment of women with endometrial cancer. At that time, there had been significant advances in the diagnosis, work-up, surgical management, and available treatment options allowing for more optimal care of affected women. This manuscript, Part II in a two-part series, includes specific recommendations on treatment of recurrent disease, post treatment surveillance and survivorship, considerations for younger women, and special situations. Part I covered histopathology and molecular pathology, risk factors, presentation and diagnostic approach, surgical approach and adjuvant therapy.

Endometrial cancer: A society of gynecologic oncology evidence-based review and recommendations.

INTRODUCTION: In 2014, the Society of Gynecologic Oncology's Clinical Practice Committee published a clinical update reviewing the treatment of women with endometrial cancer. At that time, there had been significant advances in the diagnosis, work-up, surgical management, and available treatment options allowing for more optimal care of affected women. Despite these advances, the incidence of endometrial cancer as well as the deaths attributable to the disease have continued to rise; from 1987 to 2014 there has been a 75% increase in cases and almost 300% increase in endometrial cancer deaths. Fortunately, since then, there has been progress in the treatment of patients with endometrial cancer with increased utilization of molecular pathology, greater understanding of genetic predisposition, enhanced methods for lymph node assessment, a broader understanding of the efficacy of radiation and chemotherapy, and a more efficient approach to survivorship and surveillance. The purpose of this document is to present a comprehensive review of this progress. MANUSCRIPT DEVELOPMENT PROCESS: The authors reviewed the available evidence, contributed to the development of this manuscript, provided critical review of the guidelines, and finalized the manuscript recommendations. The review was also presented to and approved by the Society of Gynecologic Oncology (SGO) Clinical Practice Committee, SGO Publications Committee, and the SGO board members prior to submission for publication. The recommendations for this manuscript were developed by a panel of gynecologic oncologists who were members of the SGO Clinical Practice and Education Committees. Panelists reviewed and considered evidence from current uterine cancer literature. The terminology used in these guidelines was adopted from the ASCCP management guidelines [1] using a two-part rating system to grade the strength of recommendation and quality of evidence (Table 1). The rating for each recommendation is given in parentheses.

Uterine Cellular Blue Nevus Arising in Mullerian and Pelvic Dendritic Melanocytosis: Case Report of a Rare Phenomenon to Be Distinguished From Uterine Melanoma.

A 37-yr-old woman presented to the gynecology clinic with abnormal uterine bleeding in the setting of known, large uterine fibroids. Preoperative endometrial biopsy identified atypical melanocytic cells concerning for uterine melanoma. Care was transferred to the gynecologic oncology service for hysterectomy. Intraoperative findings included macular, blue-black pigmentation of the peritoneum of the bladder and cervix, which was resected and sent for frozen section, confirming melanocytic neoplasia. The hysterectomy revealed multiple tan leiomyomas up to 12 cm, and a distinct 3 cm black, incompletely circumscribed mass in the endomyometrium composed of bland spindled cells with delicate melanin granules. The tumor cells were positive for Sox-10, BAP1, and Mart-1 (Melan-A) and negative for PRAME, PD-L1, and BRAFV600E by immunostains. Microscopic elements of similar melanocytes and melanophages were found in the cervix and bladder peritoneum. Molecular analysis of the uterine tumor identified a GNA11 mutation but no TERT or BAP1 mutation. The uterine melanocytic tumor has characteristic findings of a cellular blue nevus arising in association with dendritic melanocytosis of Mullerian and pelvic tissues, a rarely seen benign phenomenon that should be distinguished from malignant melanoma of the upper genital tract.

Accuracy of preoperative cross-sectional imaging in cervical cancer patients undergoing primary radical surgery.

OBJECTIVE: We aim to describe the false negative (FN) and false positive (FP) rates of preoperative cross-sectional imaging (PCI) prior to radical surgery for cervical cancer. METHODS: A retrospective cohort study of patients who underwent radical hysterectomy for early-stage cervical cancer from January 2010 until December 2017 at a single tertiary care center was performed. Patients were included if they underwent preoperative PCI and radical surgery. Patient demographics and clinicopathologic information were recorded from medical record review. Descriptive statistics were used. RESULTS: Overall, 106 patients met inclusion criteria. Eighty-four percent (89/106) of patients had no suspicion for metastatic disease on PCI, while 16% (17/106) had suspicion for metastatic disease. Of the 89 without suspicion for metastatic disease on PCI, 16% (14/89) had a false negative study with metastatic disease identified on final surgical pathology. False negative rates by modality were 16% (11/70) for PET/CT and 6% (2/33) for diagnostic CT. Of the 17 cases with suspicion for metastatic disease on imaging, 53% (9/17) were false positive studies with no metastatic disease identified histologically. False positive rates by modality were 7% (5/70) for PET/CT and 12% (4/33) for diagnostic CT. CONCLUSION: PCI is a tool to help identify patients who are optimal candidates for radical surgery. In this sample, the false negative rate was 16%, and false positive rate was 53% for PCI among women who underwent primary radical surgery. Further study is needed to explore preoperative testing that may more accurately identify optimal surgical candidates.

Are There Survival Differences Between Women with Equivalent Residual Disease After Interval Cytoreductive Surgery Compared with Primary Cytoreductive Surgery for Advanced Ovarian and Peritoneal Cancer?

OBJECTIVE: The aim of this study was to investigate survival differences between equivalent residual disease [complete gross resection (CGR), minimal residual disease (MRD), suboptimal] at the time of primary debulking surgery (PDS) and interval debulking surgery (IDS). METHODS: The National Cancer Database was used to identify patients from 2010 to 2015 with stage IIIC/IV primary peritoneal or ovarian cancer who had residual disease recorded. Propensity score matching (PSM) was used to correct for differences in characteristics between the PDS and IDS groups. RESULTS: Of 8683 patients with advanced ovarian cancer, 4493 (52%), 2546 (29%), and 1644 (19%) had CGR, MRD, or suboptimal resection, respectively. From 2010 to 2015, the number of patients undergoing IDS increased 27% (ptrend < 0.001), and there was an 18% increase in CGRs (ptrend = 0.005). The increased use of IDS from 2010 to 2015 was associated with increased CGRs (ptrend = 0.02) and decreased MRD (ptrend = 0.001), but not with decreased suboptimal resections (ptrend = 0.18). IDS, even after PSM, was associated with inferior overall survival [OS; hazard ratio (HR) 1.12, 95% confidence interval (CI) 1.03-1.22, p = 0.008]. A CGR at PDS had prolonged median OS compared with a CGR at IDS (51 vs. 44 months, p < 0.001). Additionally, MRD at PDS had worse median OS compared with a CGR at IDS (41 vs. 44 months, p = 0.03), but improved median OS compared with MRD at IDS (median OS 35 months, p = 0.05). CONCLUSION: The use of IDS continues to rise in the US, and is associated with improved surgical outcomes but not necessarily similar oncologic outcomes. There should be continued efforts to improve cytoreductive outcomes in women with advanced ovarian and peritoneal malignancies.

Adjuvant treatment improves overall survival in women with high-intermediate risk early-stage endometrial cancer with lymphovascular space invasion.

BACKGROUND: Adjuvant therapy in early-stage endometrial cancer has not shown a clear overall survival benefit, and hence, patient selection remains crucial. OBJECTIVE: To determine whether women with high-intermediate risk, early-stage endometrial cancer with lymphovascular space invasion particularly benefit from adjuvant treatment in improving oncologic outcomes. METHODS: A multi-center retrospective study was conducted in women with stage IA, IB, and II endometrial cancer with lymphovascular space invasion who met criteria for high-intermediate risk by Gynecologic Oncology Group (GOG) 99. Patients were stratified by the type of adjuvant treatment received. Clinical and pathologic features were abstracted. Progression-free and overall survival were evaluated using multivariable analysis. RESULTS: 405 patients were included with the median age of 67 years (range 27-92, IQR 59-73). 75.0% of the patients had full staging with lymphadenectomy, and 8.6% had sentinel lymph node biopsy (total 83.6%). After surgery, 24.9% of the patients underwent observation and 75.1% received adjuvant therapy, which included external beam radiation therapy (15.1%), vaginal brachytherapy (45.4%), and combined brachytherapy + chemotherapy (19.1%). Overall, adjuvant treatment resulted in improved oncologic outcomes for both 5-year progression-free survival (77.2% vs 69.6%, HR 0.55, p=0.01) and overall survival (81.5% vs 60.2%, HR 0.42, p<0.001). After adjusting for stage, grade 2/3, and age, improved progression-free survival and overall survival were observed for the following adjuvant subgroups compared with observation: external beam radiation (overall survival HR 0.47, p=0.047, progression-free survival not significant), vaginal brachytherapy (overall survival HR 0.35, p<0.001; progression-free survival HR 0.42, p=0.003), and brachytherapy + chemotherapy (overall survival HR 0.30 p=0.002; progression-free survival HR 0.35, p=0.006). Compared with vaginal brachytherapy alone, external beam radiation or the addition of chemotherapy did not further improve progression-free survival (p=0.80, p=0.65, respectively) or overall survival (p=0.47, p=0.74, respectively). CONCLUSION: Adjuvant therapy improves both progression-free survival and overall survival in women with early-stage endometrial cancer meeting high-intermediate risk criteria with lymphovascular space invasion. External beam radiation or adding chemotherapy did not confer additional survival advantage compared with vaginal brachytherapy alone.

Recurrence Rates in Patients With Cervical Cancer Treated With Abdominal Versus Minimally Invasive Radical Hysterectomy: A Multi-Institutional Retrospective Review Study.

PURPOSE: To compare the disease-free survival (DFS) between open and minimally invasive radical hysterectomies (RH) performed in academic medical institutions. METHODS: Retrospective multi-institutional review of patients undergoing RH for stage IA1 (with lymphovascular invasion), IA2, and IB1 squamous, adenocarcinoma, or adenosquamous carcinoma between January 1, 2010 and December 31, 2017. RESULTS: Of 815 patients, open RH was performed in 255 cases (29.1%) and minimally invasive RH in 560 cases (70.9%). There were 19 (7.5%) recurrences in the open RH and 51 (9.1%) recurrences in the minimally invasive group (P = .43). Risk-adjusted analysis revealed that minimally invasive RH was independently associated with an increased hazard of recurrence (aHR, 1.88; 95% CI, 1.04 to 3.25). Other factors independently associated with an increased hazard of recurrence included tumor size, grade, and adjuvant radiation. Conization before surgery was associated with lower recurrence risk (aHR, 0.4; 95% CI, 0.23 to 0.71). There was no difference in OS in the unadjusted analysis (HR, 1.14; 95% CI, 0.61 to 2.11) or after risk adjustment (aHR, 1.01; 95% CI, 0.5 to 2.2). Of 264 patients with tumors ≤ 2 cm on final pathology (excluding those with no residual tumor on final pathology), 2/82 (2.4%) recurred in the open RH group and 16/182 (8.8%) in the minimally invasive RH group (P = .058). In propensity score matching analysis, 7/159 (4.4%) recurrences were noted in the open RH group and 18/156 (11.5%) in the minimally invasive RH group (P = .019). Survival analysis revealed an increased risk of recurrence in the minimally invasive group in propensity-matched cohort (HR, 2.83; 95% CI, 1.1 to 7.18). CONCLUSION: In this retrospective series, patients undergoing minimally invasive radical hysterectomy, including those with tumor size ≤ 2 cm on final pathology, had inferior DFS but not overall survival in the entire cohort.

Adjuvant therapy for early stage, endometrial cancer with lymphovascular space invasion: Is there a role for chemotherapy?

OBJECTIVES: Lymphovascular space invasion (LVSI) is an independent risk factor for recurrence and poor survival in early-stage endometrioid endometrial cancer (EEC), but optimal adjuvant treatment is unknown. We aimed to compare the survival of women with early-stage EEC with LVSI treated postoperatively with observation (OBS), radiation (RAD, external beam and/or vaginal brachytherapy), or chemotherapy (CHEMO)+/-RAD. METHODS: This was a multi-institutional, retrospective cohort study of women with stage I or II EEC with LVSI who underwent hysterectomy+/-lymphadenectomy from 2005 to 2015 and received OBS, RAD, or CHEMO+/-RAD postoperatively. Progression-free survival and overall survival were evaluated using Kaplan-Meier estimates and Cox proportional hazards models. RESULTS: In total, 478 women were included; median age was 64 years, median follow-up was 50.3 months. After surgery, 143 (30%) underwent OBS, 232 (48.5%) received RAD, and 103(21.5%) received CHEMO+/-RAD (95% of whom received RAD). Demographics were similar among groups, but those undergoing OBS had lower stage and grade. A total of 101 (21%) women recurred. Progression-free survival (PFS) was improved in both CHEMO+/-RAD (HR = 0.18, 95% CI: 0.09-0.39) and RAD (HR = 0.31, 95% CI: 0.18-0.54) groups compared to OBS, though neither adjuvant therapy was superior to the other. However, in grade 3 tumors, the CHEMO+/-RAD group had superior PFS compared to both RAD (HR 0.25; 95% CI: 0.12-0.52) and OBS cohorts (HR = 0.10, 95% CI: 0.03-0.32). Overall survival did not differ by treatment. CONCLUSIONS: In early-stage EEC with LVSI, adjuvant therapy improved PFS compared to observation alone. In those with grade 3 EEC, adjuvant chemotherapy with or without radiation improved PFS compared to observation or radiation alone.

Sarcopenia as a predictor of survival and chemotoxicity in patients with epithelial ovarian cancer receiving platinum and taxane-based chemotherapy.

OBJECTIVES: Severe skeletal muscle loss (sarcopenia) is associated with poor cancer outcomes, including reduced survival and increased treatment toxicity. Our goal was to evaluate if sarcopenia was associated with worse survival outcomes and chemotoxicity in EOC patients undergoing primary platinum and taxane-based chemotherapy. METHODS: EOC patients diagnosed between 06/2000 and 02/2017 who received treatment with platinum and taxane-based chemotherapy were included. CT abdominal images closest to the time of diagnosis were retrospectively evaluated for skeletal muscle area at the 3rd lumbar vertebrae. Measurements were obtained with use of TomoVision® radiological software (SliceOmatic - version 5.0, Quebec, Canada). Sarcopenia was defined as Skeletal Muscle Index (SMI) ≤ 41. Data analysis included Kaplan-Meier plots to assess survival, and unpaired t-tests were used to compare the means by groups. RESULTS: 201 EOC patients were evaluated. Sixty-four percent (128/201) met criteria for sarcopenia (SMI ≤ 41) at time of diagnosis. The mean overall survival did not differ between patients with SMI > 41 and SMI ≤ 41 (36.5 vs 40.8 months, p = 0.4, respectively). No difference in frequency of dose reduction, dose delay, hospital admissions, changes in regimen, blood transfusion, or toxicity was noted. There was no difference in distribution of toxicity grade. CONCLUSION: Sarcopenia was not associated with worse survival outcomes or chemotoxcity in EOC patients receiving first-line platinum and taxane-based chemotherapy in this cohort. Future prospective studies should focus on interventions to prevent or reverse sarcopenia and possibly increase ovarian cancer survival, performance status, and quality of life.

Defining the learning curve for successful staging with sentinel lymph node biopsy for endometrial cancer among surgeons at an academic institution.

BACKGROUND: Sentinel lymph node (SLN) biopsy is increasingly used in endometrial cancer staging; however, success of the technique is variable, and the learning curve needs to be better understood. Success is defined as identification of a SLN specimen containing nodal tissue in bilateral hemi-pelvises. OBJECTIVE: To assess the learning curve of surgeons at an academic institution in performing successful SLN mapping and biopsy during robotic staging for endometrial cancer. METHODS: After institutional review board approval, patients who underwent staging with robotic SLN mapping using indocyanine green at a single academic program between July 2012 and December 2017 were identified. Demographic, pathologic, and surgical data were retrospectively collected from the medical records. Descriptive and comparative statistics were performed. Surgeon rates of successful bilateral SLN mapping and removal of lymphoid-containing SLN specimens were compared. A logistic model was used to analyze the probability of successful SLN mapping and removal of lymph node-containing tissue with increasing number of procedures performed. RESULTS: Three hundred and seventeen patients met the eligibility criteria. Most had early-stage, low-grade endometrial cancer. A total of 194 (61%) patients had successful bilateral mapping. Among seven surgeons, a plateau in rates of successful bilateral mapping was achieved after 40 cases. No linear correlation was seen between the number of surgeries performed and the rate of removal of lymph node-containing tissue among surgeons. Each additional 10 procedures performed was associated with a 5% and an 11% increase in the odds of successful SLN mapping and removal of lymph node-containing tissue, respectively. DISCUSSION: The successful removal of lymph node-containing specimens appears to be a surgeon-specific phenomenon. The plateau of the learning curve for successful bilateral mapping seems to be reached at around 40 cases. These first 40 cases offer a time for auditing of individual rates of SLN mapping and removal to identify surgeons who may benefit from procedure-specific remediation.

Prospective Evaluation of Multinational Association of Supportive Care in Cancer Risk Index Score for Gynecologic Oncology Patients With Febrile Neutropenia.

BACKGROUND: The Multinational Association of Supportive Care of Cancer (MASCC) risk-index score has been validated as a stratification tool for febrile neutropenia (FN) risk in a heterogeneous group of cancer patients; recently, it has been deemed a suitable tool in gynecologic oncology patients in a retrospective study. This is a prospective multi-institutional study wherein we sought to validate MASCC score for stratifying FN morbidity in gynecologic oncology patients. METHODS: IRB approval was obtained at 4 institutions for prospective data collection of gynecologic cancer patients admitted with FN from 3/1/2013 to 9/1/2014. Participating institutions have a policy of inpatient management of FN patients receiving chemotherapy. Deidentified data was compiled and processed at the leading institution. RESULTS: In total, 31 patients met inclusion criteria. Most had advanced stage disease (67%). 100% of patients were receiving chemotherapy (57% for primary, 43% for recurrent disease). 55% had a positive culture. Median MASCC score was 21 (range, 10 to 26); 58% of patients were considered low risk. High risk patients more often had one (11% vs. 38%, P=0.09) or multiple (6% vs. 23%, P=0.28) severe complications, ICU admission (0% vs. 15%, P=0.17), and delay in next chemotherapy cycle (33% vs. 54%, P=0.25). No patients died from FN during the study period. CONCLUSIONS: This pilot data suggests that MASCC score may be a promising tool for determining suitability of outpatient management of FN in gynecologic oncology patients. Larger studies are warranted to achieve statistically significant results, which may enable us to effectively utilize this risk stratification tool for cost containment and avoidance of nosocomial infections.

Cost effectiveness of neoadjuvant chemotherapy followed by interval cytoreductive surgery versus primary cytoreductive surgery for patients with advanced stage ovarian cancer during the initial treatment phase.

OBJECTIVE: Advanced stage epithelial ovarian cancer (AEOC) can be treated with either neoadjuvant chemotherapy (NACT) or primary cytoreductive surgery (PCS). Although randomized controlled trials show that NACT is non-inferior in overall survival compared to PCS, there may be improvement in short-term morbidity. We sought to investigate the cost-effectiveness of NACT relative to PCS for AEOC from the US Medicare perspective. METHODS: A cost-effectiveness analysis using a Markov model with a 7-month time horizon comparing (1) 3cycles of NACT with carboplatin and paclitaxel (CT), followed by interval cytoreductive surgery, then 3 additional cycles of CT, or (2) PCS followed by 6cycles of CT. Input parameters included probability of chemotherapy complications, surgical complications, treatment completion, treatment costs, and utilities. Model outcomes included costs, life-years gained, quality-adjusted life-years (QALYs) gained, and incremental cost-effectiveness ratios (ICER), in terms of cost per life-year gained and cost per QALY gained. We accounted for differences in surgical complexity by incorporating the cost of additional procedures and the probability of undergoing those procedures. Probabilistic sensitivity analysis (PSA) was performed via Monte Carlo simulations. RESULTS: NACT resulted in a savings of $7034 per patient with a 0.035 QALY increase compared to PCS; therefore, NACT dominated PCS in the base case analysis. With PSA, NACT was the dominant strategy more than 99% of the time. CONCLUSIONS: In the short-term, NACT is a cost-effective alternative compared to PCS in women with AEOC. These results may translate to longer term cost-effectiveness; however, data from randomized control trials continues to mature.

Surgical readmission and survival in women with ovarian cancer: Are short-term quality metrics incentivizing decreased long-term survival?

OBJECTIVES: To determine the association between treatment with neoadjuvant chemotherapy (NACT) or primary debulking surgery (PDS) and readmission after surgical hospitalization as well as overall survival among women with stage IIIC epithelial ovarian cancer (EOC). METHODS: We identified incident cases of stage IIIC EOC treated with both chemotherapy and surgery in the National Cancer Database (NCDB) from 2006 to 2012. 30-day readmissions were categorized as planned or unplanned. Log binomial models were used to estimate risk ratios and 95% confidence intervals. Survival analysis was performed using cox proportional hazards models. RESULTS: We identified 20,853 women with stage IIIC EOC. 15.6% (n=3242) were treated with NACT and 11.6% (n=2427) were readmitted within 30days of surgery, 59% (n=1421) were unplanned. NACT was associated with a 48% reduction in the risk of any readmission (aRR 0.52 95%CI 0.45-0.60) compared to PDS with adjustment for age, race, insurance, histology, year of diagnosis, and Charlson co-morbidity index score. However, in the same population, receipt of neoadjuvant chemotherapy was also associated with a 33% increase in the rate of death (HR 1.33 95%CI 1.29-1.40) with adjustment for the same factors. CONCLUSIONS: Among women with stage IIIC EOC, NACT is associated with both decreased rates of readmission and decreased survival compared to PDS. While selection bias may account for some of the observed differences in survival, the current focus on short-term hospital-wide quality metrics, such as postoperative readmission, in the ovarian cancer population, may be creating incentives inconsistent with long-term goals.
