RESUMEN
OBJECTIVE: To compare radical hysterectomy case volume, cancer stage, and biopsy-to-treatment time of invasive cervical cancer diagnosed before and after onset of the COVID-19 pandemic. METHODS: In a multi-institution retrospective cohort study conducted at 6 large, geographically diverse National Cancer Institute-designated cancer centers, patients treated for newly diagnosed invasive cervical cancer were classified into 2 temporal cohorts based on date of first gynecologic oncology encounter: (1) Pre-Pandemic: 3/1/2018-2/28/2020; (2) Pandemic & Recovery: 4/1/2020-12/31/2021. The primary outcome was total monthly radical hysterectomy case volume. Secondary outcomes were stage at diagnosis and diagnosis-to-treatment time. Statistical analyses used chi-squared and two sample t-tests. RESULTS: Between 3/1/2018-12/31/2021, 561 patients were diagnosed with cervical cancer. The Pre-Pandemic and Pandemic & Recovery cohorts had similar age, race, ethnicity, smoking status, and Body Mass Index (BMI). During Pandemic & Recovery, the mean monthly radical hysterectomy case volume decreased from 7[SD 2.8] to 5[SD 2.0] (p = 0.001), the proportion of patients diagnosed with Stage I disease dropped from 278/561 (49.5%) to 155/381 (40.7%), and diagnosis of stage II-IV disease increased from 281/561 (50.1%) to 224/381 (58.8%). Primary surgical management was less frequent (38.3% Pandemic & Recovery versus 46.7% Pre-Pandemic, p = 0.013) and fewer surgically-treated patients received surgery within 6 weeks of diagnosis (27.4% versus 38.9%; p = 0.025). CONCLUSIONS: Lower radical hysterectomy case volume, a shift to higher cervical cancer stage, and delay in surgical therapy were observed across the United States following the COVID-19 outbreak. Decreased surgical volume may result from lower detection of early-stage disease or other factors.

OBJECTIVE: The collection of a peritoneal cytologic sample at the time of surgery for endometrial cancer has traditionally been an important part of surgical staging. In 2009, the International Federation of Gynecology and Obstetrics revised the cancer staging schema for endometrial cancer and removed peritoneal cytology from the staging criteria. The current National Comprehensive Cancer Network guidelines and the International Federation of Gynecology and Obstetrics organization, however, recommend evaluation of peritoneal cytology at the time of hysterectomy. This study examined population-based trends, characteristics, and outcomes of peritoneal cytologic sampling for endometrial cancer surgery following the 2009 staging revision in the United States. METHODS: This is a retrospective observational study querying the Surveillance, Epidemiology, and End Results Program to examine women with stage I-III endometrial cancer who underwent hysterectomy from 2010 to 2017. Trends, characteristics, and survival associated with peritoneal cytologic evaluation at the time of hysterectomy were assessed in multivariable analysis and with propensity score weighting. RESULTS: Among 62,809 women who underwent hysterectomy, 43,873 (69.9%) had peritoneal cytologic evaluation at surgery and 18,936 (30.1%) did not. Utilization of peritoneal cytologic evaluation decreased from 75.5% to 64.9% during the study period (P < 0.001). In multivariable analysis, more recent year of surgery was independently associated with a decreased likelihood of performance of peritoneal cytology (adjusted-odds ratio of peritoneal cytology evaluation in 2017 versus 2010 0.56, 95% confidence interval [CI] 0.52-0.60). Peritoneal cytologic evaluation at the time of hysterectomy was associated with improved all-cause mortality (hazard ratio in the whole cohort 0.94, 95%CI 0.89-0.99; and hazard ratio in endometrioid histology 0.90, 95%CI 0.84-0.97). CONCLUSION: Performance of peritoneal cytologic sampling has gradually decreased following the 2009 staging revision in the United States. Our study suggests that peritoneal cytology evaluation at hysterectomy may be associated with improved survival in certain tumor groups.

Granulosa cell tumors of the ovary (GCT) are the most common type of sex cord stromal tumors. Although most of patients are diagnosed at early stage and has favorable 5-year overall survival rate, 16-23% of GCT ultimately develop recurrent disease. Recurrences are characterized by disseminated peritoneal metastasis. The treatment options include systemic chemotherapy, secondary CRS or palliative localized radiation therapy have not yet standardized due to the rarity of disease. Aggressive CRS followed up by hyperthermic intraperitoneal chemotherapy (HIPEC) has been shown to provide benefit in other peritoneal disease but limited data available for recurrent GCT. We have a case of recurrent Adult-type GCT (AGCT) who was treated with CRS followed by HIPEC with mitomycin C and doxorubicin. The patient has no evidence of recurrence for approximately 11 years. An electronic search of the PubMed database with the following search terms: GCT, HIPEC showed that there were total 21 patients with recurrent GCT treated in seven different studies and 13 of 21 (61.9%) patients had no evidence of disease during follow-up ranging from 6 to 100 months. Three patients (14.2%) died of the disease. Six studies used cisplatin for HIPEC. At least 76.2% (16 of 21, data not available for five patients) had complete cytoreduction with total 16 cases of perioperative complications but no perioperative mortality was observed. Although further investigation is needed, we propose that CRS and HIPEC can be an effective therapeutic option for recurrent GCT at experienced institutions.

Little is known about the neuronal mechanism underpinning the pathophysiology of compulsive hoarding. We report the cerebral blood flow changes in an obsessive-convulsive patient with severe hoarding. The patient showed hyperperfusion of the fronto-temporal region and hypoperfusion of the striatal, the middle cingulate and the medial temporal regions during the stage with severe symptoms. Following improvement from the hoarding behaviors, the extent of hypoperfusion was expanded in the bilateral striatum, the anterior and middle cingulate gyrus. The result may substantiate evidence of the fronto-limbic abnormality involved in the pathophysiology of compulsive hoarding.

This study aimed to investigate the antitumor and antiangiogenic effects utilizing a novel therapy regimen of metronomic topotecan and pazopanib, a multireceptor tyrosine kinase inhibitor. In vitro (Western blot) and in vivo dose-finding experiments were done following pazopanib therapy in ovarian cancer models. Pazopanib and metronomic (daily) oral topotecan therapy was examined in an orthotopic model of ovarian cancer. Tumor weights, survival, and markers of the tumor microenvironment [angiogenesis (CD31 and pericyte coverage), proliferation (Ki-67), and apoptosis (terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling)] were analyzed by immunostaining following therapy. Pazopanib therapy reduced vascular endothelial growth factor receptor 2 (VEGFR-2) activity in vitro and vivo in a dose-dependent manner. Compared with control mice, pazopanib reduced tumor weight by 28% to 82% (P < 0.01 in the SKOV3ip1 model) and metronomic topotecan reduced tumor weight by 40% to 59% in the HeyA8 (P = 0.13) and SKOV3ip1 (P = 0.07) models. Combination therapy had the greatest effect with 79% to 84% reduction (P < 0.01 for both models). In the SKOV3ip1 and A2780 models, mouse survival was significantly longer (P < 0.001 versus controls) with pazopanib and metronomic topotecan therapy. Pazopanib therapy reduced murine endothelial cell migration in vitro in a dose-dependent manner following VEGF stimulation and decreased tumor microvessel density and pericyte coverage when given in combination with metronomic topotecan. Tumor cell proliferation decreased in all treatment arms compared with controls (P < 0.01 for combination groups) and increased tumor cell apoptosis by 4-fold with combination therapy. Pazopanib therapy in combination with metronomic topotecan therapy showed significant antitumor and antiangiogenic properties in preclinical ovarian cancer models and warrants further investigation as a novel therapeutic regimen in clinical trials.

Eye movement desensitization and reprocessing (EMDR) is an effective psychological intervention for posttraumatic stress disorder (PTSD). Trauma-related recall (Recall) with eye movements (EMs) is thought to reduce distress. However, the neural mechanisms underlying this process remain unknown. Thirteen patients with PTSD received EMDR treatment over the course of 2-10 weeks. We assessed the change in hemoglobin concentration in the lateral prefrontal cortex (PFC) during Recall with and without EM using multi-channel near-infrared spectroscopy (NIRS). Clinical diagnosis and improvement were evaluated using the Clinician-Administered PTSD Scale. Recall with EM was associated with a significant decrease in oxygenated hemoglobin concentration ([oxy-Hb]) in the lateral PFC as compared with Recall without EM. Longitudinally, [oxy-Hb] during Recall significantly decreased and the amount of decrease was significantly correlated with clinical improvement when the post-treatment data was compared with that of the pre-treatment. Our results suggest that performing EM during Recall reduces the over-activity of the lateral PFC, which may be part of the biological basis for the efficacy of EMDR in PTSD. NIRS may be a useful tool for objective assessment of psychological intervention in PTSD.

Near-infrared spectroscopy (NIRS) has the potential for clinical application in neuropsychiatry because it enables non-invasive and convenient measurement of hemodynamic response to cognitive activation. Using 24-channel NIRS in 12 healthy men, we examined the replicability of oxy- and deoxy-hemoglobin concentration ([oxyHb], [deoxyHb]) changes in the prefrontal cortex during the category fluency task over four repeated sessions (each 1-week apart). Multiple methods were employed to evaluate the replicability of magnitude, location, and time course of the NIRS signals ([oxyHb], [deoxyHb]). Task performances did not differ significantly across sessions, nor were they significantly correlated with NIRS signals. Repeated measures ANOVA and variance component analysis indicated high replicability of magnitude for both NIRS measures, whereas the effect sizes of between-session differences in [oxyHb] were not negligible. The number and spatial location of significantly activated channels were sufficiently replicable for both measures, except that the across-session overlap of significantly activated channels was weak in [deoxyHb]. The time course of the activation was acceptably replicable in both measures. Taken together, these findings suggest there is considerable replicability of multiple-time measurements of prefrontal hemodynamics during cognitive activation in men. Further studies using different conditions or assessing sensitivity to longitudinal changes following interventions are necessary.
