HPV vaccination coverage for pediatric, adolescent and young adult patients receiving care in a childhood cancer survivor program.

Pediatric, adolescent and young adult patients undergoing cancer treatment and/or hematopoietic stem cell transplant are at increased risk for developing a secondary human papillomavirus (HPV)-associated malignancy. The objective of this study was to determine HPV vaccination coverage among individuals participating in a childhood cancer survivor program (CCSP). A retrospective cohort study was conducted among CCSP patients age 11-26 years attending a CCSP visit between 2014 and 2019. Survivors were age-, sex-, and race-matched 1:2 with controls without cancer. Data were abstracted from the electronic health record and state-based vaccination registry. Analysis was limited to Minnesota residents to minimize missing vaccination data. Survivorship care plans (SCPs) were reviewed for vaccine recommendations. 592 patients were included in the analyses (200 CCSP patients; 392 controls). By study design, mean age (18.4 years), race (72 % white), and sex (49 % female) were similar in the two groups. Among CCSP patients 22 % resided in a rural area compared to 3.8 % of controls. Vaccination coverage among CCSP patients was not statistically significantly different from controls [60.0 % vs 66.3 %, OR = 0.82, 95 % CI: (0.55, 1.23), p = 0.35]. Completion of 3 doses was not different between groups even though 3 doses is recommended for all CCSP patients regardless of age at initiation (28.5 % vs 30.1 %, p = 0.09). Only 8.0 % of SCPs recommended HPV vaccination. Although patients participating in a CCSP did not have significantly different HPV vaccination coverage compared to controls, HPV vaccination initiation and 3-dose series completion are still suboptimal in a patient population at high-risk of a secondary HPV-associated cancer.

Interactions between physical activity and type of cancer treatment received on associations with psychosocial outcomes among gynecologic cancer survivors.

OBJECTIVE: Physical activity is associated with improved cancer outcomes; however, it is unclear which patients may benefit most from increased physical activity. We evaluated whether associations between meeting the American Cancer Society (ACS) physical activity recommendations and psychosocial outcomes in gynecologic cancer survivors varied by type of treatments received. METHODS: We recruited English-speaking adult gynecologic cancer patients from an academic gynecologic oncology practice to participate in a prospective cohort study. Participants completed a survey at study entry regarding their psychosocial health-including distress, depression, anxiety, post-traumatic stress disorder, and quality of life (QoL)-and physical activity. Multivariate linear regression models for each psychosocial outcome tested for interactions between physical activity and each effect modifier (receipt of chemotherapy, radiation therapy, and/or minimally invasive surgery), adjusted for age, pain, body mass index, primary cancer diagnosis, cancer stage, time since diagnosis, and annual household income. RESULTS: Among a total of 362 participants, 213 (59%) met ACS physical activity recommendations. We found evidence of interactions between physical activity and receipt of chemotherapy for depression, anxiety, and QoL scores; those who had received chemotherapy had a stronger association between physical activity and these psychosocial outcomes, compared to those who had not. We found no evidence of interactions between physical activity and receipt of radiation therapy or minimally invasive surgery for any of the outcomes. CONCLUSIONS: Gynecologic cancer survivors who received chemotherapy had significant associations between psychosocial health and physical activity, suggesting they may derive greatest benefit from prescribed exercise.

Cross-sectional study of psychosocial well-being among lesbian, gay, bisexual, and heterosexual gynecologic cancer survivors.

BACKGROUND: Delays in care and increased risk for mental health diagnoses put individuals identifying as a sexual minority with cancer at risk for decreased quality of life. AIM: To assess psychosocial health among sexual minority gynecologic cancer survivors, we compared self-reported quality of life and psychosocial measures between individuals diagnosed with gynecologic cancers identifying as lesbian/gay/bisexual (LGB) and heterosexual. METHODS AND RESULTS: English-speaking adults with gynecologic cancers were invited to participate in an ongoing cohort survey study. Quality of life and psychosocial measures included the Functional Assessment of Cancer Therapy-General, Distress Thermometer (distress), Patient Health Questionnaire-8 (depression), General Anxiety Disorder-7 (anxiety), and Post-traumatic Stress Disorder Checklist for DSM-5 (post-traumatic stress disorder; PTSD). Measures were compared by self-reported sexual orientation (heterosexual vs. LGB) using descriptive statistics (frequencies and means) and linear and logistic regression models, adjusting for college education. Of 814 patients invited, 457 enrolled (56.1%) and 401 (92.6%) completed the survey and provided information on their sexuality. All but one self-identified as cisgender women and 22 (5.5%) as LGB. LGB participants were more likely to have completed college (68.2% vs. 40.1%, p = .009) but were otherwise similar across demographic and clinical characteristics. Quality of life and distress scores were similar between groups. LGB participants, compared to heterosexual, reported higher rates of depression (31.8% vs. 10.6%, adjusted odds ratio [OR] = 4.1 [95% confidence interval [CI]: 1.6-11.0], p = .004), anxiety (25.0% vs. 7.1%, adjusted OR = 5.4 [95% CI: 1.7-16.7], p= .004), and PTSD (13.6% vs. 3.5%, adjusted OR = 4.2 [95% CI: 1.1-16.3], p = .04). CONCLUSION: LGB participants reported poorer emotional health following a gynecologic cancer diagnosis than heterosexual participants. Our data suggest this population may need additional resources and support during and after their cancer diagnosis. Future work is needed to identify additional risk factors and the underlying sources of these disparities in order to improve patient care and wellness in this population.

Genetic variants predictive of chemotherapy-induced peripheral neuropathy symptoms in gynecologic cancer survivors.

OBJECTIVE: To identify genetic variants associated with chemotherapy-induced peripheral neuropathy (CIPN) symptoms among gynecologic cancer survivors and determine the variants' predictive power in addition to age and clinical factors at time of diagnosis. METHODS: Participants of a prospective cohort study on gynecologic cancers provided a DNA saliva sample and reported CIPN symptoms (FACT/GOG-Ntx). Genotyping of 23 single nucleotide polymorphisms (SNPs) previously identified as related to platinum- or taxane-induced neuropathy was performed using iPLEX Gold method. Risk allele carrier frequencies of 19 SNPs that passed quality checks were compared between those with/without high CIPN symptoms using logistic regression, adjusting for age. Receiver operating characteristic (ROC) curves using clinical risk factors (age, diabetes, BMI, Charlson Comorbidity Index, previous cancer diagnosis) with and without the identified SNPs were compared. RESULTS: 107 individuals received platinum or taxane-based chemotherapy and provided sufficient DNA for analysis. Median age was 65.1 years; 39.6% had obesity and 8.4% diabetes; most had ovarian (58.9%) or uterine cancer (29.0%). Two SNPs were significantly associated with high CIPN symptomatology: rs3753753 in GPX7, OR = 2.55 (1.13, 5.72) and rs139887 in SOX10, 2.66 (1.18, 6.00). Including these two SNPs in a model with clinical characteristics led to an improved AUC for CIPN symptomatology (0.65 vs. 0.74, p = 0.04). CONCLUSIONS: Genetic and clinical characteristics were predictive of higher CIPN symptomatology in gynecologic cancer survivors, and combining these factors resulted in superior predictive power compared with a model with clinical factors only. Prospective validation and assessment of clinical utility are warranted.

Comparisons of emotional health by diagnosis among women with early stage gynecological cancers.

OBJECTIVE: To assess self-reported emotional health in a cohort of women with early stage gynecologic cancers and to explore differences based on primary cancer type. METHODS: We analyzed survey data from a cohort study of gynecological cancer patients treated at an academic cancer center. Measures of emotional health included cancer-related quality of life, distress, depression, anxiety, posttraumatic stress disorder (PTSD), and posttraumatic growth. Univariate and multivariate linear regression models examined differences in emotional health measures by primary cancer site. Potential confounders considered for inclusion in the final models were age, stage, education, income, partner status, treatment status, and race. RESULTS: 242 patients with early stage disease completed the survey. Patients with cervical and vaginal/vulvar cancers reported greater cancer-related distress, anxiety and PTSD symptoms. Patients with endometrial cancer reported the lowest posttraumatic growth scores, which remained statistically significant after adjustment for demographic and clinical differences. No significant differences in cancer-related quality of life were observed among individuals with different primary cancer sites CONCLUSIONS: These data suggest patients with early-stage gynecologic cancer face different psychosocial sequelae based on primary cancer site, though underlying clinical and sociodemographic factors may play a significant role in this observed relationship. Further research is needed to assess poorer emotional health among individuals with vaginal/vulvar cancers and the lower posttraumatic growth among patients with endometrial cancer as posttraumatic growth is considered a potentially beneficial psychosocial outcome of cancer.

Emotional health concerns of oncology physicians in the United States: Fallout during the COVID-19 pandemic.

INTRODUCTION: Cancer care is significantly impacted by the Coronavirus Disease 2019 (COVID-19) pandemic. Our objective was to evaluate the early effects of the pandemic on the emotional well-being of oncology providers across the United States and explore factors associated with anxiety and depression symptoms. MATERIALS AND METHODS: A cross-sectional survey was administered to United States cancer-care physicians recruited over a two-week period (3/27/2020-4/10/2020) using snowball-convenience sampling through social media. Symptoms of anxiety and depression were measured using the Patient Health Questionnaire (PHQ-4). RESULTS: Of 486 participants, 374 (77.0%) completed the PHQ-4: median age was 43 years; 63.2% female; all oncologic specialties were represented. The rates of anxiety and depression symptoms were 62.0% and 23.5%, respectively. Demographic factors associated with anxiety included female sex, younger age, and less time in clinical practice. Perception of inadequate personal protective equipment (68.6% vs. 57.4%, p = 0.03) and practicing in a state with more COVID-19 cases (65.8% vs. 51.1%, p = 0.01) were associated with anxiety symptoms. Factors significantly associated with both anxiety and depression included the degree to which COVID-19 has interfered with the ability to provide treatment to cancer patients and concern that patients will not receive the level of care needed for non-COVID-19 illness (all p-values <0.01). CONCLUSION: The perceived degree of interference with clinical practice along with personal concerns about COVID-19 were significantly associated with both anxiety and depression among oncology physicians in the United States during the COVID-19 pandemic. Our findings highlight factors associated with and sources of psychological distress to be addressed to protect the well-being of oncology physicians.

Perspectives of cancer patients and their health during the COVID-19 pandemic.

INTRODUCTION: The immunosuppressive nature of some cancers and many cancer-directed treatments may increase the risk of infection with and severe sequelae from Coronavirus Disease 2019 (COVID-19). The objective of this study was to compare concerns about COVID-19 among individuals undergoing cancer treatment to those with a history of cancer not currently receiving therapy and to those without a cancer history. METHODS: We conducted a cross-sectional anonymous online survey study of adults currently residing in the United States. Participants were recruited over a one-week period (April 3-11, 2020) using promoted advertisements on Facebook and Twitter. Groups were compared using chi-squared tests, Fisher's exact tests, and t-tests. RESULTS: 543 respondents from 47 states provided information on their cancer history and were included in analyses. Participants receiving active treatment reported greater concern about infection from the SARS-CoV-2 coronavirus (p<0.001), higher levels of family distress caused by the COVID-19 pandemic (p = 0.004), and greater concern that the general public does not adequately understand the seriousness of COVID-19 (p = 0.04). Those with metastatic disease were more likely to indicate that COVID-19 had negatively affected their cancer care compared to patients with non-metastatic cancer (50.8% vs. 31.0%; p = 0.02). The most commonly reported treatment modifications included chemotherapy delays. CONCLUSIONS: Patients undergoing active treatment for cancer were most concerned about the short-term effects of the COVID-19 pandemic on the logistics as well as potential efficacy of ongoing cancer treatment, longer term effects, and overarching societal concerns that the population at large is not as concerned about the public health implications of SARS-CoV-2 infection.

Cancer Management During the COVID-19 Pandemic in the United States: Results From a National Physician Cross-sectional Survey.

OBJECTIVES: The coronavirus disease 2019 (COVID-19) has significantly impacted health care delivery across the United States, including treatment of cancer. We aim to describe the determinants of treatment plan changes from the perspective of oncology physicians across the United States during the COVID-19 pandemic. METHODS: Participants were recruited to an anonymous cross-sectional online survey of oncology physicians (surgeons, medical oncologists, and radiation oncologists) using social media from March 27 to April 10, 2020. Physician demographics, practice characteristics, and cancer treatment decisions were collected. RESULTS: The analytic cohort included 411 physicians: 241 (58.6%) surgeons, 106 (25.8%) medical oncologists, and 64 (15.6%) radiation oncologists. In all, 38.0% were practicing in states with 1001 to 5000 confirmed COVID-19 cases as of April 3, 2020, and 37.2% were in states with >5000 cases. Most physicians (N=285; 70.0% of surgeons, 64.4% of medical oncologists, and 73.4% of radiation oncologists) had altered cancer treatment plans. Most respondents were concerned about their patients' COVID-19 exposure risks, but this was the primary driver for treatment alterations only for medical oncologists. For surgeons, the primary driver for treatment alterations was conservation of personal protective equipment, institutional mandates, and external society recommendations. Radiation oncologists were primarily driven by operational changes such as visitor restrictions. CONCLUSIONS: The COVID-19 pandemic has caused a majority of oncologists to alter their treatment plans, but the primary motivators for changes differed by oncologic specialty. This has implications for reinstitution of standard cancer treatment, which may occur at differing time points by treatment modality.

Our findings highlight factors associated with and sources of psychological distress to be addressed to protect the well-being of oncology physicians.

The associations between physical activity, neuropathy symptoms and health-related quality of life among gynecologic cancer survivors.

OBJECTIVE: Physical activity may mitigate the effects of cancer treatment. We sought to evaluate the association between self-reported physical activity, neuropathy symptomatology, and emotional health in gynecologic cancer survivors. METHODS: Patients were recruited from an academic gynecologic oncology practice to a prospective cohort study. Participants completed semiannual surveys on quality of life (QOL), neuropathy symptoms, depression, distress, and health behaviors. Abstracted clinical data included cancer type, FIGO stage at diagnosis and treatments received (chemotherapy, surgery, radiation). Physical activity [no: moderate physical activity <150 min/week, yes: ≥150 min/week] and neuropathy symptomatology [high (FACT/GOG-Ntx ≥11; upper quartile); low (<11)] were dichotomized. Linear regression models assessed the associations between physical activity, neuropathy and psychosocial outcomes. RESULTS: A total of 194 participants were included in this analysis. We identified significant interactions between physical activity and neuropathy in the depression (p = 0.0006) and QOL (p = 0.007) models. Greater physical activity and lower neuropathy scores were independently associated with fewer depressive symptoms (p = 0.02 and p < 0.0001, respectively) and greater QOL (p = 0.005 and p < 0.0001). Low neuropathy scores were associated with lower distress (p < 0.0001). Women with high neuropathy scores had larger beneficial associations between being physically active and depression and QOL. In the distress model, interaction between neuropathy and physical activity was suggested (p = 0.05). CONCLUSIONS: Physical activity was associated with favorable psychosocial outcomes in gynecologic cancer survivors, most notably among those with worse neuropathy. These data suggest prescriptive exercise should be evaluated as a means of mitigating cancer-associated neuropathies and their effect on emotional health.

Molecular characterization of endometrial cancer and therapeutic implications.

PURPOSE OF REVIEW: The present article reviews molecular subtyping and genomic characterization of endometrial carcinoma, and the associated therapeutic and prognostic implications. RECENT FINDINGS: Endometrial cancer has historically been classified through histology into endometrioid and nonendometrioid subtypes with poor prognostic predictability. Molecular classification through genomic analysis now allows for a major advance in characterization. Four distinct subgroups have been identified: polymerase (POLE) ultramutated, microsatellite unstable, copy number-low--microsatellite stable, and copy number-high-'serous-like'. These subtypes have prognostic implications and may aid in the identification of early-stage patients who are at high risk for recurrence. Through analysis of surrogate markers (POLE, MSI, and p53) and other validated molecular alterations (L1CAM), it is possible to obtain an integrated molecular risk profile that relates to prognosis. Studies utilizing this risk profile in order to identify patients who may benefit from adjuvant treatment for early-stage disease are on-going. SUMMARY: Molecular characterization of endometrial cancer into subgroups has enhanced prognostic and therapeutic implications, contrary to traditional risk stratification. Further development of an integrated molecular risk profile may identify patients who could most benefit from adjuvant treatment following surgery and tailor treatment decisions in the recurrent setting.

Knowledge of pelvic floor disorders in women seeking primary care: a cross-sectional study.

BACKGROUND: Pelvic floor disorders including urinary incontinence (UI) and pelvic organ prolapse (POP) are common conditions; however, most women with these symptoms do not seek care. Failure to seek care may be related to misconceptions about these conditions. The aim of this study was to assess the baseline knowledge of UI and POP among adult women presenting to primary care clinics, as well as factors associated with knowledge levels. METHODS: A survey with questions from previously validated UI and POP knowledge questionnaires (PIKQ-UI and PIKQ-POP, respectively) was self-administered to a cross-sectional group of adult female patients presenting to three primary care clinics: geriatric, community-based, and hospital-based. Participants' demographics and medical histories were compared using ANOVA or Kruskal-Wallis for continuous variables and Chi-square test or Fisher's exact test for categorical variables. In order to compare various covariates with knowledge non-proficiency on PIKQ-UI and PIKQ-POP scales, unadjusted and adjusted ORs with 95% CIs were calculated using bivariate analysis and multivariate logistic regression, respectively. RESULTS: Of 346 participants, knowledge non-proficiency was similar and consistent across clinic sites and reached 72.0% for UI and 53.6% for POP. On multivariate analysis, lower educational attainment, being unaware of UI or POP as medical conditions, and having no history of care-seeking for these conditions were significantly associated with knowledge non-proficiency on UI, POP, or both. CONCLUSIONS: Knowledge non-proficiency for UI and POP is common among women presenting for primary care. For UI, healthcare providers should assess patients' actual understanding of the disease, especially among those with lower educational attainment, to eliminate any possible misconceptions. For POP, the focus should be on increasing awareness of this disease, as many women may have not previously heard of this condition. Simple strategies may increase knowledge in these areas and change care-seeking behaviors. STUDY REGISTRATION: None.

Risk of empty lymph node packets in sentinel lymph node mapping for endometrial cancer using indocyanine green.

OBJECTIVE: To determine whether the rate of sentinel lymph node (SLN) dissections that do not yield a lymph node on pathological analysis ('empty packet dissection') changes with increasing surgeon experience in the setting of patients undergoing minimally invasive hysterectomy and SLN mapping using indocyanine green dye for endometrial cancer. METHODS: All patients undergoing SLN mapping using indocyanine green dye at the time of minimally invasive hysterectomy for endometrial cancer or complex atypical hyperplasia were identified between January 2013 and September 2017 at our institution. All surgeons had prior experience performing SLN mapping for endometrial cancer using other methods. The rate of empty packet dissections and SLN counts were evaluated using a logistic regression model analysis. RESULTS: In total, 236 patients undergoing SLN mapping for either endometrial cancer (85%) or complex atypical hyperplasia (15%) were identified from a prospectively maintained database. When examining all six surgeons together, the percentage of empty packet dissections decreased with increasing number of procedures performed. Each additional procedure was associated with a 3.6% reduction in the odds of an empty packet SLN dissection. After adjusting for individual surgeons, each additional procedure was associated with a 4.9% reduction in the odds of an empty packet. The expected odds of an empty packet after 10 additional procedures decreased by 40.1% (95% CI 12.4% to 58.6%). The addition of two covariates (age and body mass index) did not contribute significantly to the model (likelihood ratio test: X2=2.75, p=0.25). The rate of empty packets appeared to stabilize after approximately 30 procedures. The number of SLNs removed did not change with increasing surgeon experience. CONCLUSION: The rate of empty packet SLN dissections using indocyanine green dye decreases with increasing number of procedures. This stabilizes after 30 procedures, suggesting completion of a learning curve.

Retention of laparoscopic and robotic skills among medical students: a randomized controlled trial.

BACKGROUND: Although simulation training beneficially contributes to traditional surgical training, there are less objective data on simulation skills retention. OBJECTIVE: To investigate the retention of laparoscopic and robotic skills after simulation training. METHODS: We present the second stage of a randomized single-blinded controlled trial in which 40 simulation-naïve medical students were randomly assigned to practice peg transfer tasks on either laparoscopic (N = 20, Fundamentals of Laparoscopic Surgery, Venture Technologies Inc., Waltham, MA) or robotic (N = 20, dV-Trainer, Mimic, Seattle, WA) platforms. In the first stage, two expert surgeons evaluated participants on both tasks before (Stage 1: Baseline) and immediately after training (Stage 1: Post-training) using a modified validated global rating scale of laparoscopic and robotic operative performance. In Stage 2, participants were evaluated on both tasks 11-20 weeks after training. RESULTS: Of the 40 students who participated in Stage 1, 23 (11 laparoscopic and 12 robotic) underwent repeat evaluation. During Stage 2, there were no significant differences between groups in objective or subjective measures for the laparoscopic task. Laparoscopic-trained participants' performances on the laparoscopic task were improved during Stage 2 compared to baseline measured by time to task completion, but not by the modified global rating scale. During the robotic task, the robotic-trained group demonstrated superior economy of motion (p = .017), Tissue Handling (p = .020), and fewer errors (p = .018) compared to the laparoscopic-trained group. Robotic skills acquisition from baseline with no significant deterioration as measured by modified global rating scale scores was observed among robotic-trained participants during Stage 2. CONCLUSION: Robotic skills acquired through simulation appear to be better maintained than laparoscopic simulation skills. CLINICAL TRIAL: This study is registered on ClinicalTrials.gov (NCT02370407).

Laparoscopic and robotic skills are transferable in a simulation setting: a randomized controlled trial.

BACKGROUND: Although surgical simulation provides an effective supplement to traditional training, it is not known whether skills are transferable between minimally invasive surgical modalities. The purpose of this study was to assess the transferability of skills between minimally invasive surgical simulation platforms among simulation-naïve participants. METHODS: Forty simulation-naïve medical students were enrolled in this randomized single-blinded controlled trial. Participants completed a baseline evaluation on laparoscopic (Fundamentals of Laparoscopic Surgery Program, Los Angeles, CA) and robotic (dV-Trainer, Mimic, Seattle, WA) simulation peg transfer tasks. Participants were then randomized to perform a practice session on either the robotic (N = 20) or laparoscopic (N = 20) simulator. Two blinded, expert minimally invasive surgeons evaluated participants before and after training using a modified previously validated subjective global rating scale. Objective measures including time to task completion and Mimic dV-Trainer motion metrics were also recorded. RESULTS: At baseline, there were no significant differences between the training groups as measured by objective and subjective measures for either simulation task. After training, participants randomized to the laparoscopic practice group completed the laparoscopic task faster (p < 0.003) and with higher global rating scale scores (p < 0.001) than the robotic group. Robotic-trained participants performed the robotic task faster (p < 0.001), with improved economy of motion (p < 0.001), and with higher global rating scale scores (p = 0.006) than the laparoscopic group. The robotic practice group also demonstrated significantly improved performance on the laparoscopic task (p = 0.02). Laparoscopic-trained participants also improved their robotic performance (p = 0.02), though the robotic group had a higher percent improvement on the robotic task (p = 0.037). CONCLUSIONS: Skills acquired through practice on either laparoscopic or robotic simulation platforms appear to be transferable between modalities. However, participants demonstrate superior skill in the modality in which they specifically train.

Peri-Implantation Hormonal Milieu: Elucidating Mechanisms of Adverse Neurodevelopmental Outcomes.

While live births resulting from assisted reproductive technology (ART) exceed 1% of total births annually, the effect of ART on fetal development is not well understood. Data have demonstrated that IVF leads to alterations in DNA methylation and gene expression in the placenta that may have long-term effects on health and disease. Studies have linked adverse neurodevelopmental outcomes to ART, although human studies are inconclusive. In order to isolate the peri-implantation environment and its effects on brain development, we utilized a mouse model with and without superovulation and examined the effect of adult behavior as well as adult cortical neuronal density. Adult offspring of superovulated dams showed increased anxiety-like behavior compared to offspring of naturally mated dams (P < .05). There was no difference in memory and learning tests between the 2 groups. The adult brains from offspring of superovulated recipients had fewer neurons per field compared to naturally mated control offspring (P < .05). In order to examine potential pathways leading to these changes, we measured messenger RNA and microRNA (miRNA) expression in fetal brains at E18.5. Microarray analysis found that miRNAs miR-122, miR-144, and miR-211, involved in regulation of neuronal migration and differentiation, were downregulated in brains of offspring exposed to a superovulated environment(P < .05). There was also altered expression of genes involved in neuronal development. These results suggest that the peri-implantation environment can affect neurodevelopment and can lead to behavioral changes in adulthood. Human studies with long-term follow-up of children from ART are necessary to further investigate the influence of ART on the offspring.

Immediate Single-Stage Cranioplasty Following Calvarial Resection for Benign and Malignant Skull Neoplasms Using Customized Craniofacial Implants.

UNLABELLED: Craniectomy defects following resection of calvarial lesions are most often reconstructed using on-table manufacturing. With the advent of computer-aided design/manufacturing and customized craniofacial implants (CCIs), there seems to be more suited alternatives. In this study, the authors report their institutional experience and outcome using immediate, single-stage, CCI-based reconstruction for benign and malignant skull neoplasm defects. METHODS: A retrospective review of a prospectively maintained database of all implant cranioplasties performed between 2011 and 2014, by a single craniofacial surgeon at a tertiary academic medical institution was performed. Preoperative and postoperative computed tomography scans with 3D reconstruction were performed for the purpose of assessing adequate resection and reconstructive outcomes. Primary endpoints included length of surgery, predicted defect versus postoperative implant surface area, contour irregularities, and complications. RESULTS: Of the 108 patients with cranioplasty identified, 7 patients were found to undergo immediate CCI-based reconstruction for calvarial neoplasms; 4 patients (4/7, 57%) presented with malignant pathology. All defects were >5  cm2. As compared with their original size, all implants were modified intraoperatively between 0.2% and 40.8%, with a mean of 13.8%. With follow-up ranging between 1 and 16 months, there were no implant-related complications identified. The immediate and long-term aesthetic results, as well as patient satisfaction, were ideal. CONCLUSION: With this preliminary experience, the authors have successfully demonstrated that immediate customized implant reconstructive techniques, by way of intraoperative modification, are both safe and feasible for benign and malignant skull neoplasms. The authors believe that with wider acceptance of this multidisciplinary approach and increased surgeon familiarity, this technique will soon become the reconstructive standard of care.

Limitation of imaging in identifying iatrogenic aortic coarctation following thoracic endovascular aortic repair.

A 21-year-old male suffered blunt trauma from a motor vehicle accident causing thoracic aorta tear. The smallest available stent graft was deployed. Definitive repair was later performed using a 22 × 22 × 116 mm Talent Thoracic Stent Graft. The postoperative course was uneventful. Seventeen months later, he presented with dizziness, chest pain, acute renal failure, malignant hypertension, and troponin elevation. Computed tomography (CT) angiogram and transesophageal echocardiogram did not reveal any dissection, stent stenosis or collapse. Cardiac catheterization showed normal coronary arteries but a 117 mm Hg gradient across the stent graft. Iatrogenic coarctation of the aorta was confirmed with a second measurement during arch angiogram. A Palmaz stent was deployed over the distal end of the previous stent graft with complete resolution of symptoms and gradual normalization of kidney function. This case report demonstrates a need for wider availability and selecting appropriate stent graft in treating traumatic aortic injuries in young patients. It is the first case report of the inability of current imaging modalities in confirming stent collapse. Pressure gradient is a useful tool in confirming stent collapse when clinical scenario does not match CT findings.
