Pressurized intraperitoneal aerosolized chemotherapy (PIPAC) experience in patients with recurrent low grade serous ovarian carcinoma (LGSOC): sub-cohort report of phase 1 clinical trial.

Introduction: Low grade serous ovarian carcinoma (LGSOC) is a rare subtype of ovarian cancer (OC) that is challenging to treat due to its relative chemoresistance. Given that LGSOC patients often recur in the peritoneal cavity, novel intraperitoneal (IP) chemotherapy should be explored. Pressurized intraperitoneal aerosolized chemotherapy (PIPAC) is a method that has demonstrated peritoneal disease control in cancers with peritoneal metastases. Methods: NCT04329494 is a US multicenter phase 1 trial evaluating the safety of PIPAC in recurrent ovarian, uterine, and GI cancers with peritoneal metastases. This analysis describes the outcomes of a sub-cohort of four LGSOC patients treated with IP cisplatin 10.5 mg/m2, doxorubicin 2.1 mg/m2 PIPAC q4-6 weeks. Primary endpoints included dose-limiting toxicities (DLT) and incidence of adverse events (AE). Secondary endpoints were progression free survival (PFS) and treatment response based on radiographic, intraoperative, and pathological findings. Results: Four patients with LGSOC were enrolled of which three were heavily pretreated. Median prior lines of therapy was 5 (range 2-10). Three patients had extraperitoneal metastases, and two patients had baseline partial small bowel obstructive (SBO) symptoms. Median age of patients was 58 (38-68). PIPAC completion rate (≥2 PIPACs) was 75%. No DLTs or Clavien-Dindo surgical complications occurred. No G4/G5 AEs were observed, and one G3 abdominal pain was reported. One patient had a partial response after 3 cycles of PIPAC and completed an additional 3 cycles with compassionate use amendment. Two patients came off study after 2 cycles due to extraperitoneal progressive disease. One patient came off study after 1 cycle due to toxicity. Median decrease in peritoneal carcinomatosis index between cycles 1 and 2 was 5.0%. Ascites decreased in 2 out of 3 patients who had ≥2 PIPACs. Median PFS was 4.3 months (1.7-21.6), median overall survival was 11.6 months (5.4-30.1), and objective response rate was 25%. Conclusion: PIPAC with cisplatin/doxorubicin is well tolerated in LGSOC patients without baseline SBO symptoms. IP response was seen in 2 out of 3 patients that completed ≥2 PIPAC cycles. Further study of PIPAC for patients with recurrent disease limited to the IP cavity and with no partial SBO symptoms should be considered.

A phase I study of Mirvetuximab Soravtansine and gemcitabine in patients with FRα-positive recurrent ovarian, primary peritoneal, fallopian tube, or endometrial cancer, or triple negative breast cancer.

OBJECTIVE: Platinum-resistant epithelial ovarian cancer (EOC), recurrent endometrial cancer (EC), and triple negative breast cancer (TNBC) are difficult to treat after failing standard therapies. This phase I study evaluated mirvetuximab soravtansine (MIRV) and gemcitabine in patients with recurrent FRα-positive EOC, EC, or TNBC to determine the maximum tolerated dose (MTD)/recommended phase 2 dose (RP2D) (primary endpoint). METHODS: FRα-positive patients with platinum-resistant EOC, EC, or TNBC with ≤4 prior chemotherapy regimens (2 for EC) were enrolled. FRα expression requirement varied among eligible tumors and changed during the study. RESULTS: Twenty patients were enrolled; 17 were evaluable for DLT. Half the patients received ≥3 prior chemotherapy lines. Most EOC and EC patients (78%) were medium (50-74%) or high(75-100%) FRα expressors. TNBC patients were low (25-49%) FRα expressors. The MTD/RP2D was MIRV 6 mg/kg AIBW D1 and gemcitabine 800 mg/m2 IV, D1 and D8, every 21 days (Dose Level [DL] 3), where 5/7 patients demonstrated a partial response (PR) as their best response, including 2 confirmed ovarian responses whose time-to-progression and duration of response were 7.9/5.4 and 8.0/5.7 months respectively. Most common treatment-related adverse events at MTD were anemia and neutropenia (3/7 each, 43%), diarrhea, hypophosphatemia, thrombocytopenia, and leukopenia (2/7 each, 29%). DLTs were thrombocytopenia (DL1), oral mucositis (DL4) and diarrhea (DL4). Nine of 20 patients (45%; 95% CI: 21.1-68.9%) achieved PR as their best response, with 3/20 patients or 15% (95%CI, 0-32.1%) confirmed PR. CONCLUSION: MIRV and gemcitabine demonstrate promising activity in platinum resistant EOC at RP2D, but frequent hematologic toxicities.

Impact of Sodium Thiosulfate on Prevention of Nephrotoxicities in HIPEC: An Ancillary Evaluation of Cisplatin-Induced Toxicities in Ovarian Cancer.

PURPOSE: Hyperthermic intraperitoneal chemotherapy (HIPEC) with cisplatin confers a survival benefit in epithelial ovarian cancer (EOC) but is associated with renal toxicity. Sodium thiosulfate (ST) is used for nephroprotection for HIPEC with cisplatin, but standard HIPEC practices vary. METHODS: A prospective, nonrandomized, clinical trial evaluated safety outcomes of HIPEC with cisplatin 75 mg/m2 during cytoreductive surgery (CRS) in patients with EOC (n = 34) and endometrial cancer (n = 6). Twenty-one patients received no ST (nST), and 19 received ST. Adverse events (AEs) were reported according to CTCAE v.5.0. Serum creatinine (Cr) was collected preoperatively and postoperatively (Days 5-8). Progression-free survival (PFS) was followed. Normal peritoneum was biopsied before and after HIPEC for whole transcriptomic sequencing to identify RNAseq signatures correlating with AEs. RESULTS: Forty patients had HIPEC at the time of interval or secondary CRS. Renal toxicities in the nST group were 33% any grade AE and 9% grade 3 AEs. The ST group demonstrated no renal AEs. Median postoperative Cr in the nST group was 1.1 mg/dL and 0.5 mg/dL in the ST group (p = 0.0001). Median change in Cr from preoperative to postoperative levels were + 53% (nST) compared with - 9.6% (ST) (p = 0.003). PFS did not differ between the ST and nST groups in primary or recurrent EOC patients. Renal AEs were associated with downregulation of metabolic pathways and upregulation of immune pathways. CONCLUSIONS: ST significantly reduces acute renal toxicity associated with HIPEC with cisplatin in ovarian cancer patients. As nephrotoxicity is high in HIPEC with cisplatin, nephroprotective agents should be considered.

Feasibility of combining pelvic reconstruction with gynecologic oncology-related surgery.

INTRODUCTION AND HYPOTHESIS: At our institution, every patient seen by the gynecologic oncology service is screened for pelvic floor dysfunction. This study was aimed at determining if a combined surgical approach by gynecologic oncology and urogynecology services at our institution was feasible and safe for this patient population. METHODS: We performed a retrospective review of patients undergoing combined surgery by gynecologic oncology and urogynecology services at our institution from 2013 to 2021. Perioperative variables, postoperative adverse events, and long-term outcomes were assessed, and descriptive statistics were performed. RESULTS: From 20 December 2013 to 29 January 2021, a total of 102 patients underwent concurrent surgical repair of pelvic organ prolapse and/or stress urinary incontinence. Seventy-three patients (71.6%) had normal/benign pathologic conditions, and 29 (28.4%) had premalignant/malignant pathologic conditions. Ten patients (9.8%) had a postoperative complication, including reoperation for exposed midurethral sling (4.9%), urinary retention requiring midurethral sling release (2.9%), reoperation for hemoperitoneum (1.0%), and anemia requiring blood transfusion (1.0%). Nine complications occurred in patients with benign/normal pathologic conditions (12.3%), and one complication occurred in patients with pre-malignant/malignant pathologic conditions (3.4%). CONCLUSIONS: In our single-institution experience, concurrent gynecologic oncology and pelvic floor reconstructive surgery were safe and feasible in combination with no reported major morbidity events.

Hyperthermic Intraperitoneal Chemotherapy-Induced Molecular Changes in Humans Validate Preclinical Data in Ovarian Cancer.

PURPOSE: Hyperthermic intraperitoneal chemotherapy (HIPEC) confers a survival benefit in epithelial ovarian cancer (EOC) and in preclinical models. However, the molecular changes induced by HIPEC have not been corroborated in humans. PATIENTS AND METHODS: A feasibility trial evaluated clinical and safety outcomes of HIPEC with cisplatin during optimal cytoreductive surgery (CRS) in patients with EOC diagnosed with stage III, IV, or recurrent EOC. Pre- and post-HIPEC biopsies were comprehensively profiled with genomic and transcriptomic sequencing to identify mutational and RNAseq signatures correlating with response; the tumor microenvironment was profiled to identify potential immune biomarkers; and transcriptional signatures of tumors and normal samples before and after HIPEC were compared to investigate HIPEC-induced acute transcriptional changes. RESULTS: Thirty-five patients had HIPEC at the time of optimal CRS; all patients had optimal CRS. The median progression-free survival (PFS) was 24.7 months for primary patients and 22.4 for recurrent patients. There were no grade 4 or 5 adverse events. Anemia was the most common grade 3 adverse event (43%). Hierarchical cluster analyses identified distinct transcriptomic signatures of good versus poor responders to HIPEC correlating with a PFS of 29.9 versus 7.3 months, respectively. Among good responders, significant HIPEC-induced molecular changes included immune pathway upregulation and DNA repair pathway downregulation. Within cancer islands, % programmed cell death protein 1 expression in CD8+ T cells significantly increased after HIPEC. An exceptional responder (PFS 58 months) demonstrated the highest programmed cell death protein 1 increase. Heat shock proteins comprised the top differentially upregulated genes in HIPEC-treated tumors. CONCLUSION: Distinct transcriptomic signatures identify responders to HIPEC, and preclinical model findings are confirmed for the first time in a human cohort.

Readmission and complications after robotic surgery: experience of 10,000 operations at a comprehensive cancer center.

Evaluation of safety is of paramount importance with adoption of novel surgical technology. Although robotic surgery has become widely used in oncologic surgery, analysis of safety is lacking in comparison to traditional techniques. Standardized assessment of robotic surgical outcomes and adverse events following oncologic surgery is necessary for quality improvement with innovative technology. Between 2003 and 2016, 10,013 unique robotic operations were performed in 9,858 patients. Our prospectively maintained database was retrospectively reviewed for hospital readmissions and Clavien-Dindo grade ≥ 2 complications within 30 days. Multivariable logistic regression was used to identify predictors of surgical complications and hospital readmissions. Cases were stratified by discipline: genitourinary (n = 8240), gynecologic (n = 857), thoracic (n = 457), gastrointestinal (n = 322), hepatobiliary (n = 60), ear/nose/throat (n = 44) and general (n = 33). Intraoperative complications occurred in 42 surgeries (0.4%). Postoperative complications occurred in 946 patients [9.4%, highest grade 2 (n = 574), 3 (n = 288), 4 (n = 72), 5 (n = 10)]. Most frequent complications were ileus (154, 16.3%), anemia (91, 9.6%), cardiac arrhythmia (62, 6.6%), deep vein thrombosis/pulmonary embolus (47, 5.0%), wound infection (45, 4.8%) and urinary leak (43, 4.5%). 405 patients (4.0%) required readmission. Most common causes for hospital readmission were ileus (44, 10.9%), urinary leak (23, 5.7%), urinary tract infection (23, 5.7%), intra-abdominal abscess/fluid collection (23, 5.7%), and small bowel obstruction (19, 4.7%). On multivariable analysis, longer operative time and older age predicted complications and readmissions (p ≤ 0.02). Robotic-assisted surgery appears a safe for oncologic surgery with acceptable hospital readmission and complication rates. Older age and longer operative time were associated with complications and readmission.

Prolapse repair after anterior exenteration.

This report presents our experience in performing prolapse repair after anterior exenteration. The patient had a history of invasive bladder cancer and underwent a robotically assisted laparoscopic anterior exenteration with extended bilateral pelvic lymph node dissection and creation of an Indiana pouch continent diversion. Her pelvic organ prolapse progressed over time despite multiple pessary fittings. She eventually decided to proceed with pelvic reconstructive surgery 6 years after her cancer surgery. She underwent a successful vaginal native tissue reconstruction with uterosacral ligament suspension, posterior repair and reconstruction of the anterior compartment. The patient has been followed for 16 months without recurrent prolapse. Vaginal native tissue pelvic reconstruction is feasible in a patient with a history of pelvic exenteration.

Specific targeting of ovarian tumor-associated macrophages by large, anionic nanoparticles.

Immunotherapy is emerging as one of the most effective methods for treating many cancers. However, immunotherapy can still introduce significant off-target toxicity, and methods are sought to enable targeted immunotherapy at tumor sites. Here, we show that relatively large (>100-nm) anionic nanoparticles administered intraperitoneally (i.p.) selectively accumulate in tumor-associated macrophages (TAMs). In a mouse model of metastatic ovarian cancer, fluorescently labeled silica, poly(lactic-co-glycolic acid), and polystyrene nanoparticles administered i.p. were all found to selectively accumulate in TAMs. Quantifying silica particle uptake indicated that >80% of the injected dose was in TAMs. Particles that were smaller than 100 nm or cationic or administered intravenously (i.v.) showed no TAM targeting. Moreover, this phenomenon is likely to occur in humans because when freshly excised human surgical samples were treated with the fluorescent silica nanoparticles no interaction with healthy tissue was seen but selective uptake by TAMs was seen in 13 different patient samples. Ovarian cancer is a deadly disease that afflicts ∼22,000 women per year in the United States, and the presence of immunosuppressive TAMs at tumors is correlated with decreased survival. The ability to selectively target TAMs opens the door to targeted immunotherapy for ovarian cancer.

A phase I trial of intraperitoneal nab-paclitaxel in the treatment of advanced malignancies primarily confined to the peritoneal cavity.

PURPOSE: To evaluate intraperitoneal (IP) nab-paclitaxel in patients with advanced malignancies that are primarily confined to the peritoneal cavity in a phase I trial. METHODS: Using a 3 + 3 dose escalation of IP nab-paclitaxel on days 1, 8, and 15 of a 28-day cycle, we evaluated six dose levels (35-175 mg/m2/dose). Maximum tolerated dose (MTD) and pharmacokinetics (PK) of IP nab-paclitaxel were determined. RESULTS: There were no dose-limiting toxicities (DLTs) in cohorts 1-3. There was a DLT in one of six patients in cohort 4 (112.5 mg/m2) (grade 3 neutropenia causing treatment delay > 15 days) and a DLT in one of three patients in cohort 6 (175 mg/m2) (grade 4 neutropenia and grade 3 abdominal pain). A second patient in cohort 6 experienced a serious adverse event (cycle 1, grade 4 ANC ≤ 7 days, cycle 4, grade 2 left ventricular dysfunction). This dose level was determined to be above the MTD. No DLTs were seen in seven patients treated in cohort 5 (140 mg/m2). The MTD of IP nab-paclitaxel was established at 140 mg/m2 on days 1, 8, and 15 of a 28-day cycle. There was a PK advantage for IP nab-paclitaxel, with an IP plasma area under the concentration-time curve (AUC) ratio of 147-fold (range 50-403) and therapeutic range systemic drug levels. Eight of 27 enrolled patients had progression-free survival ≥ 6 months. One patient experienced complete response, and one patient experienced partial response. Six patients had stable disease. CONCLUSIONS: Weekly IP nab-paclitaxel has a favorable toxicity profile, a significant pharmacologic advantage, and promising clinical activity. CLINICAL TRIAL REGISTRATION: NCT00825201.

This portion of the guidelines describes recommendations regarding the management of anthracycline-induced cardiotoxicity and lymphedema. In addition, recommendations regarding immunizations and the prevention of infections in cancer survivors are included.

Improved survival with adjuvant brachytherapy in stage IA endometrial cancer of unfavorable histology.

PURPOSE: We evaluated the utilization of vaginal brachytherapy (BT) and the resulting impact on survival in stage IA endometrial cancer of clear cell (CC), papillary serous (PS), and carcinosarcoma (CS) histology. METHODS: Patients with uterine cancer diagnosed from 2004 to 2015 were identified from the National Cancer Database. Patients underwent hysterectomy, showing FIGO stage IA disease with CC, PS, or CS histology. Logistic regression was used to evaluate predictors of BT utilization and to generate propensity scores. Survival was compared using log-rank test and Cox proportional hazards modeling, with propensity score adjustment. RESULTS: We identified 5711 patients who underwent hysterectomy showing FIGO pT1a, N0 or NX endometrial cancer with CC, PS, or CS histology, of which 29.5% received BT. Multivariate predictors of increased receipt of BT were identified. With a median follow-up of 3.3 years, 3-year overall survival (OS) was 87% for those receiving BT versus 78% for those without (p < 0.001). A survival benefit to BT was maintained across histologies. Similar results were seen whether tumor was confined to endometrium or had <50% myometrial invasion. On multivariate analysis, receipt of BT was associated with increased survival (hazard ratio [HR] 0.75, 95% confidence interval 0.65-0.87, p < 0.001). The benefit of BT persisted after propensity score adjustment (HR 0.76, p < 0.001). CONCLUSIONS: In this cohort of women with stage IA endometrial cancer of unfavorable histology, the use of BT was associated with improved survival. In this study, 29.5% of patients in our cohort received BT.

Concurrent pelvic reconstruction and minimally invasive pelvic cancer surgery.

INTRODUCTION AND HYPOTHESIS: We present our experience in performing concurrent prolpase repair at the time of gynecologic cancer surgery. METHODS: The uterosacral ligaments are tagged before performing hysterectomy and pelvic dissection. The uterosacral ligament suspensory sutures are then placed laparoscopically after completion of pelvic cancer surgery. The remainder of the prolapse surgery is performed through a transvaginal approach. RESULTS: Many of our patients who undergo concurrent prolapse repair and gynecolgical cancer surgery receive chemotherapy and pelivc radiation. Concuurent prolapse repair improves their prolaspe symptoms. CONCLUSION: Concurrent prolapse repair should be performed at the same time as gynecologic cancer surgery.

Hypothermia Is Associated with Surgical Site Infection in Cytoreductive Surgery with Hyperthermic Intra-Peritoneal Chemotherapy.

BACKGROUND: Maintenance of peri-operative normothermia remains a global quality metric for hospitals. Hypothermia is associated with surgical site infections (SSIs) in colorectal surgery. Patients undergoing cytoreductive surgery (CRS) with hyperthermic intra-peritoneal chemotherapy (HIPEC) can experience multiple complications post-operatively. We sought to investigate the association of peri-operative hypothermia with SSIs in patients undergoing CRS/HIPEC at our institution. PATIENTS AND METHODS: Patients undergoing CRS/HIPEC from 2009-2017 were identified retrospectively from a prospectively collected institutional database. Hypothermia defined as less than 36.0°C in accordance with the Agency for Healthcare Research and Quality metric. Regression analyses were performed with SSIs diagnosed within 30 days post-operatively as the primary outcome. RESULTS: A total of 170 patients were identified, 14 (8.2%) of whom developed an SSI. Patients who developed an SSI experienced lower median temperatures (p = 0.027) and a greater percentage of operative time in hypothermia (p = 0.008). On a multivariable analysis adjusting for known risk factors for SSI, the percentage of operative time in hypothermia (odds ratio [OR] 1.04, 95% confidence interval [CI] 1.01-1.07, p = 0.008) was the only parameter associated with SSI within 30 days post-operatively. CONCLUSION: Hypothermia is associated with the development of SSIs in patients undergoing CRS/HIPEC. Our findings suggest that minimizing peri-operative temperatures to less than 36.0°C may decrease peri-operative SSI in this patient population.

Survival Benefit of Adjuvant Brachytherapy After Hysterectomy With Positive Surgical Margins in Cervical Cancer.

PURPOSE: We evaluated the use of brachytherapy (BT) in addition to external beam radiation therapy (EBRT) and the resulting effect on survival in patients with cervical cancer after hysterectomy with positive surgical margins. METHODS AND MATERIALS: Patients with cervical cancer diagnosed from 2004 to 2015 who underwent hysterectomy followed by adjuvant EBRT were identified using the National Cancer Database. Only patients with positive surgical margins were included for analysis. Logistic regression was used to evaluate predictors of BT use and for propensity score matching. Survival was compared between patients receiving EBRT alone and those receiving EBRT combined with BT for adjuvant treatment. Survival analysis using log-rank test and Cox proportional hazards modeling was performed in the overall and propensity score-matched cohorts. RESULTS: We identified 1719 patients who underwent hysterectomy with positive surgical margins followed by adjuvant radiation therapy, of whom 778 (45.3%) received additional BT. Predictors of increased receipt of BT included age >55 years, private rather than government insurance, radiation treatment duration ≥7 weeks, EBRT dose ≥4500 cGy, and time between radiation and surgery ≤9 weeks. With a median follow-up of 3.8 years, 3-year overall survival was 79.4% in patients receiving BT compared with 71.9% in patients receiving EBRT alone (log-rank P < .001). On multivariate analysis, EBRT and BT were associated with significantly improved survival (hazard ratio 0.77; 95% confidence interval 0.64-0.92; P = .003) compared with EBRT alone. The survival benefit of combining EBRT and BT persisted on propensity score-matched analysis (log-rank P = .005). CONCLUSIONS: In women with positive margins after hysterectomy for cervical cancer, the combination of EBRT and BT showed significantly improved overall survival compared with EBRT alone. However, only 45.3% of patients in our cohort received BT.

A collaborative surgical approach to upper and lower abdominal cytoreductive surgery in ovarian cancer.

BACKGROUND AND OBJECTIVES: Cytoreductive surgery with complete macroscopic resection in patients with ovarian cancer is associated with improved survival. Institutional reports of combined upper and lower abdominal cytoreductive surgery for more advanced disease have described multidisciplinary approaches. We sought to investigate outcomes in patients undergoing cytoreductive surgery in patients with upper and lower abdominal disease at our institution. METHODS: Patients who underwent cytoreductive surgery for ovarian malignancies from 2008 to 2015 were retrospectively identified from an institutional database. Upper abdominal cytoreduction was defined anatomically as debulking of disease proximal to the ligament of Treitz. Perioperative outcomes were analyzed. RESULTS: A total of 258 operations were performed, the majority for serous ovarian carcinoma (70%). The gynecologic oncologist was the primary surgeon and often assisted by either a surgical oncology fellow and/or attending. In operations with combined upper and lower abdominal cytoreduction, patients were more likely to have an American society of anesthesiologists physical status classification system (ASA) of 3, peritoneal implants, and liver/spleen metastases. Preoperative chemotherapy and optimal cytoreduction were similar between groups. Perioperative morbidity and mortality were not significantly different between groups. CONCLUSIONS: A collaborative surgical approach to combined upper and lower abdominal cytoreductive surgery in patients with ovarian cancer should be performed, if needed, to achieve an optimal cytoreduction.

The Comprehensive Complication Index: a New Measure of the Burden of Complications After Hyperthermic Intraperitoneal Chemotherapy.

BACKGROUND: Cytoreduction and hyperthermic intraperitoneal chemotherapy (HIPEC) are complex surgeries with multiple comorbidities. The Clavien-Dindo classification (CDC) is the most commonly used method to report surgical morbidity, but limits it to the highest-grade complication. The Comprehensive Complication Index (CCI) is a score ranging from 0 to 100, calculated using all 30-day complications and their treatment after abdominal surgery. The aim of this study is to assess the CCI's validity in the HIPEC patient population. METHODS: A review of our institutional cytoreduction database from 2009 to 2015 was undertaken. Patient demographics, pathology, Peritoneal Carcinomatosis Index (PCI), complications and their treatments, and length of stay (LOS) were reviewed. The CCI was calculated for each patient. Linear regression was used to assess whether the CCI and CDC were predictors of LOS. RESULTS: Of 157 patients reviewed, 110 (70.1%) underwent HIPEC. The majority were female (77, 66.9%), and the mean age was 53.7 years. Mean PCI was 13.2 [interquartile range (IQR) 7-18]. Median CDC was grade 2 (IQR 0-2), and only 9.8% had CDC of grade 4 or higher. Mean CCI was 21.4, while the median was 20.9 (IQR 0-30.8). Mean LOS was 16.2 days, while the median was 11 days (IQR 8-15 days). The CCI strongly correlated with LOS with coefficient of 0.46 [95% confidence interval (CI) 0.38-0.54, p = 0.000]. CONCLUSIONS: The CCI is an adequate tool to capture all complications and their overall burden in patients having undergone HIPEC. This study shows that the CCI can predict LOS and could be used to quantify and compare the burden of multiple complications.

Surgery Versus Radiation Treatment for High-Grade Neuroendocrine Cancer of Uterine Cervix: A Surveillance Epidemiology and End Results Database Analysis.

OBJECTIVES: The objective of this study was to assess treatment and other factors impacting survival in cervical high-grade neuroendocrine carcinoma (HGNEC). METHODS/MATERIALS: We identified patients with cervical HGNECs diagnosed during 1988 to 2012 in the Surveillance Epidemiology and End Results database. We determined overall survival by International Federation of Gynecology and Obstetrics stages and by local treatment modalities, that is, radical surgery versus external beam radiation treatment (EBRT) plus brachytherapy using Kaplan-Meier analysis with log-rank test. We also determined factors of age, stage, and treatment modality impacting survival using proportional hazard analysis. RESULTS: We identified 832 cases of cervical HGNECs in the database. After excluding cases with incomplete stage data, the International Federation of Gynecology and Obstetrics stages I to IV distributions were 196 (28.0%), 69 (9.9%), 175 (25.0%), and 260 patients (37.1%), respectively. Radical surgery and primary radiotherapy yielded similar 5-year overall survival for stages I (61% vs 53%, P = 0.27), II (48% vs 28%, P = 0.308), and III (33% vs 28%, P = 0.408) patients. External beam radiation treatment plus brachytherapy did not yield superior survival than EBRT alone in stage I (48% vs 49%, P = 0.799), II (37% vs 20%, P = 0.112), or III (25% vs 32%, P = 0.636) patients. Age (P = 0.004) and stage (stage II: hazard ratio [HR], 1.78, P = 0.013; stage III: HR, 2.42; P < 0.001) were independent factors impacting survival but not local treatment modality (EBRT: HR, 1.30, P = 0.17; EBRT plus brachytherapy: HR, 1.16; P = 0.417). CONCLUSIONS: Patients with cervical HGNECs had poor prognosis. Primary treatment by radical surgery or external beam radiotherapy with or without brachytherapy yielded equally poor survival.

Survivorship, Version 2.2017, NCCN Clinical Practice Guidelines in Oncology.

Many cancer survivors experience menopausal symptoms, including female survivors taking aromatase inhibitors or with a history of oophorectomy or chemotherapy, and male survivors who received or are receiving androgen-ablative therapies. Sexual dysfunction is also common in cancer survivors. Sexual dysfunction and menopause-related symptoms can increase distress and have a significant negative impact on quality of life. This portion of the NCCN Guidelines for Survivorship provide recommendations for screening, evaluation, and treatment of sexual dysfunction and menopausal symptoms to help healthcare professionals who work with survivors of adult-onset cancer in the posttreatment period.

Association of Fluid Administration With Morbidity in Cytoreductive Surgery With Hyperthermic Intraperitoneal Chemotherapy.

IMPORTANCE: Cytoreductive surgery (CRS) with hyperthermic intraperitoneal chemotherapy (HIPEC) for peritoneal cancers can be associated with significant complications. Randomized trials have demonstrated increased morbidity with liberal fluid regimens in abdominal surgery. OBJECTIVE: To investigate the association of intraoperative fluid administration and morbidity in patients undergoing CRS/HIPEC. DESIGN, SETTING, AND PARTICIPANTS: A retrospective analysis of information from a prospectively collected institutional database was conducted at a National Cancer Institute-designated comprehensive cancer center. A total of 133 patients from April 15, 2009, to June 23, 2016, with primary or secondary peritoneal cancers were included. EXPOSURES: Cytoreductive surgery with hyperthermic intraperitoneal chemotherapy. MAIN OUTCOMES AND MEASURES: Morbidity associated with intraoperative fluid management calculated by the comprehensive complication index, which uses a formula combining all perioperative complications and their severities into a continuous variable from 0 to 100 in each patient. RESULTS: Of the 133 patients identified, 38% and 37% had diagnoses of metastatic appendiceal and colorectal cancers, respectively. Mean age was 54 (interquartile range [IQR], 47-64) years, and mean peritoneal cancer index was 13 (IQR, 7-18). Mitomycin and platinum-based chemotherapeutic agents were used in 96 (72.2%) and 37 (27.8%) of the patients, respectively. Mean intraoperative fluid (IOF) rate was 15.7 (IQR, 11.3-18.7) mL/kg/h. Mean comprehensive complication index (CCI) was 26.0 (IQR, 8.7-36.2). On multivariate analysis, age (coefficient, 0.32; 95% CI, 0.01-0.64; P = .04), IOF rate (coefficient, 0.97; 95% CI, 0.19-1.75; P = .02), and estimated blood loss (coefficient, 0.02; 95% CI, 0.01-0.03; P = .002) were independent predictors of increased CCI. In particular, patients who received greater than the mean IOF rate experienced a 43% increase in the CCI compared with patients who received less than the mean IOF rate (31.5 vs 22.0; P = .02). CONCLUSIONS AND RELEVANCE: Intraoperative fluid administration is associated with a significant increase in perioperative morbidity in patients undergoing CRS/HIPEC. Fluid administration protocols that include standardized restrictive fluid rates can potentially help to mitigate morbidity in patients undergoing CRS/HIPEC.
