Age has been evaluated as a prognostic factor in cervical cancer in both hospital- and population-based studies. Results regarding the relation of age and cervical cancer prognosis are conflicting. This study pursued a contemporary assessment of the association of extreme young age at the time of a cervical cancer diagnosis on survival.
Institutional review board approval was obtained, and retrospective data collection at 2 academic institutions was performed. Inclusion criteria involved women ≤35 years diagnosed with cervical cancer between 1990 and 2012. Data included demographic and prognostic information pertinent to survival and progression. Characteristics of very young (≤25 years) and young (>25–35 years) women were compared. Kaplan-Meier estimates, the log-rank test, and Cox proportional hazards modeling were used to assess the association of age, tumor histology, grade, stage, and parametrial involvement with progression-free survival (PFS) and overall survival (OS).
Incident cases (n = 126) of cervical cancer in patients ≤35 years of age were identified of which complete clinical information was available for 114 women. Fifteen percent (17 of 114) were ≤25 years, with the remaining 85% (97 of 114) being 26 to 35 years of age. Race, smoking status, and marital status were comparable between the 2 groups. Squamous histology dominated overall (77 of 114; 68%) with adenocarcinoma contributing ~25% (30 of 114; 26%) of cases. The majority (96 of 114, 84%) had either stage 1A (31 of 114, 27%) or 1B (65 of 114, 57%) disease. A log-rank test revealed no evidence to infer a difference in either PFS or OS among the age groups (P = 0.511 and P = 0.340). In a univariate analysis, grade and stage significantly affected OS (P < 0.0001, P = 0.045), and stage significantly affected PFS (P < 0.0001). In multivariate modeling, presence of parametrial involvement and histologic cancer type significantly affected both PFS (P = 0.002, P = 0.001) and OS (P = 0.001, P = 0.001).
Tumor histology, parametrial involvement, and stage continue to be strong prognosticators for PFS and OS. Progression and survival outcomes are age independent in women with cervical cancer ≤35 years of age. Further study of a larger young cohort may potentially yield different outcomes.

IntroductionDespite improvement in progression-free survival with poly (ADP-ribose) polymerase inhibitors (PARPi) as maintenance therapy for ovarian cancer, many patients will eventually progress on therapy. Oligoprogression is uniquely suited to considerations of local consolidation therapy in this setting, but not commonly used in ovarian cancer. In this study we evaluated the proportion of patients on PARPi maintenance who developed limited sites of disease, the location of progression, and their natural history.MethodsFrom January 2006 to December 2020, natural language processing software (DEEP6AI) was used to identify 58 patients with ovarian cancer treated with PARPi maintenance after complete or partial response after surgery and platinum-based chemotherapy at our institution. Patients were assessed for presence and location of recurrence based on radiologic findings.ResultsThe median patient age was 65 (IQR 57–71) years. Patients had a median of two lines of chemotherapy prior to starting PARPi. With a median follow-up of 48 (range 12–149) months, 32 (55%) patients had a recurrence on maintenance olaparib and 11 (34%) patients developed oligoprogression (≤3 sites). For the 11 patients with oligoprogression, three patients developed recurrence in one site, five in two sites, and three in three sites. The sites of oligoprogression were pelvic/periaortic nodal (27%), peritoneal (27%), liver (27%), lung/mediastinal (14%), and brain (5%). The median progression-free survival for the entire cohort was 6.0 months (95% CI 4.2 to 7.8); median overall survival was not met. There were no significant differences in overall survival (p=0.81) or progression-free survival (p=0.95) between patients with and without oligoprogression.ConclusionsOne-third of patients on PARPi maintenance experienced oligoprogression defined as limited to ≤3 sites. These patients may benefit from local consolidation therapy. A larger dataset is needed to validate these findings to assess if trials investigating local therapy for these patients is of value.

Gemcitabine and Docetaxel Compared With Observation, Radiation, or Other Chemotherapy Regimens as Adjuvant Treatment for Stage I-to-IV Uterine Leiomyosarcoma
2016
ObjectivesWe aimed to compare progression-free survival (PFS) and overall survival (OS) among patients with stage I-to-IV uterine leiomyosarcoma (uLMS) who received adjuvant gemcitabine-docetaxel, were observed, received radiation only, or were treated with a chemotherapy regimen other than gemcitabine-docetaxel.Methods/MaterialsThis is a retrospective cohort study of 128 women with uLMS. Data included age, body mass index, race, stage, mitotic count, residual disease, adjuvant treatment, PFS, and OS. Variables were compared by Fisher exact or Wilcoxon rank-sum tests. Time to progression or death was plotted using Kaplan-Meier curves. Cox proportional hazards regression was used to estimate hazard ratios for progression or death by patient and tumor characteristics.ResultsFifty-six (44%) women received adjuvant chemotherapy, 41 (32%) received adjuvant radiation, and 31 (24%) were observed. Of those receiving chemotherapy, 30 received gemcitabine-docetaxel, and 26 received other chemotherapy. Disease stage for the chemotherapy groups was evenly distributed. In the radiation group, 80% of patients had early-stage disease. Age, body mass index, and residual disease were similar between the groups. Mitotic count was uniformly 10 or greater only in the gemcitabine-docetaxel group. Age, stage, and residual disease were associated with worst PFS and OS. After adjusting for these variables, there was no difference in PFS or OS between gemcitabine-docetaxel and the other treatment groups.ConclusionsThere was no difference in PFS or OS in women with uLMS treated with adjuvant gemcitabine-docetaxel versus those who were observed or received radiation only or a chemotherapy regimen other than gemcitabine-docetaxel. There is a need to identify novel therapies to treat this aggressive disease.

Timing of robotic hysterectomy after cervical excisional procedure
2019
IntroductionWhile traditional teaching has been to wait 6 weeks between cervical excisional procedure and hysterectomy, studies have produced conflicting evidence, with data supporting a delay of anywhere between 48 hours to 6 weeks depending on surgical approach. Our study sought to evaluate if the time between cervical excisional procedure and robotic hysterectomy impacts peri-operative complication rates.MethodsA retrospective cohort of patients who underwent robotic hysterectomy from August 2006 to December 2013 for cervical dysplasia or International Federation of Gynecology and Obstetrics (FIGO) 2009 stage IA1–B1 cervical cancer at a single tertiary care center was performed. Patients were categorized into three groups: early surgical intervention (<6 weeks from excisional procedure), delayed surgical intervention (≥6 weeks from excisional procedure), and no excisional procedure. Secondary analysis was performed by hysterectomy type (simple vs radical). Peri-operative outcomes and complications were compared. Statistical analysis included Chi-square, Fisher’s exact test, and Wilcoxon rank sum test.ResultsA total of 160 patients were identified. Of these, 32 (20.0%) had early surgical intervention, 52 (32.5%) had delayed surgical intervention, and 76 (47.5%) had no excisional procedure. There was no difference between groups in complication rates, including average estimated blood loss (82 vs 55 vs 71 mL; p=0.07), urologic injury (0% in all groups; p=1.0), anemia (3% vs 0% vs 1%; p=0.47), infection (0% vs 2% vs 3%; p=1.0), vaginal cuff separation (0% in all groups; p=1.0), or venous thromboembolism (0% vs 0% vs 1%; p=1.0). Additionally, there were no differences in length of stay (p=0.18) or 30-day readmission rates (p=1.0). Finally, there were no significant differences in peri-operative outcomes when stratified by radical versus simple hysterectomy.DiscussionWaiting 6 weeks between cervical excisional procedure and robotic hysterectomy does not impact peri-operative complication rates. This suggests that the time from excisional procedure should not factor into surgical planning for those who undergo robotic hysterectomy.

ObjectiveOpen radical hysterectomy followed by adjuvant radiation for cervical cancer has been associated with significant rates of morbidity. Radical hysterectomy is now often performed robotically. We sought to examine if the robotic platform decreased the morbidity associated with radical hysterectomy followed by adjuvant radiation.Materials/MethodsA retrospective cohort of patients with cervical cancer undergoing radical hysterectomy from 1995 to 2013 was evaluated. Complications were assessed using electronic record review and graded. χ2 tests and Student t tests were used for analysis.ResultsOverall, 243 patients underwent radical hysterectomy for cervical cancer. Surgical approach was 43% open and 57% robotic. Eighty-three patients (34.2%) required adjuvant radiation. Overall, radical hysterectomy plus adjuvant radiation was associated with increased risk of complication (29%) compared to radical hysterectomy alone (7%) (P < 0.001). Complications included lymphedema (n = 18), bowel-associated complications (n = 10), and urinary complications (n = 7). There was no difference in time to initiation of radiation between open and robotic surgery (43 vs 47 days; P = 0.33). There was no difference in grade 2/3 complications in patients receiving adjuvant radiation between open and robotic surgery (27.5% vs 27.9%; P = 0.97). Patients undergoing open surgery followed by radiation experienced a trend toward increased adhesion-related complications, such as bowel obstruction and ureteral stricture (10% vs 2.3%; P = 0.19); whereas patients undergoing robotic surgery followed by radiation experienced a trend toward increased lymphedema (19% vs 8%; P = 0.20).ConclusionsWe found no difference in long-term complications between patients who underwent robotic surgery compared to open radical hysterectomy with adjuvant radiation. There may be fewer adhesion-related complications with robotic surgery. However, as many radiation-related complications occur at later time points, continued follow-up to evaluate for potential differences between the 2 groups is necessary.

An exploratory study of disordered thinking with aggressive children in foster care
2005
This exploratory study examines the prevalence of disordered thinking in a sample of aggressive children in foster care between the ages 6 through 12 using the Rorschach Inkblot Method. Current literature shows that in the spectrum of aggressive behavior manifested by children in foster care, those who display more serious aggression show aggressive behaviors that are overt, constant and have psychotic or psychopathic elements. The frequencies of the Rorschach scores (SCZI and PTI and measured by the Special Scores, X-%, M-responses and S-responses) were examined by the categories of overt aggressive behavior and the type of placement. The results were compared to normative samples and data of inpatient children and adolescents. Results from this study indicate that approximately one-third of the sample exhibited a significant level of disordered thinking similar to inpatient samples. Study suggests that future research examine specific variables and qualitative studies to help address issues of placement stability and provision of mental health services.

The most common type of cancer diagnosed during pregnancy is melanoma, followed by cervical cancer, Hodgkin's lymphoma, breast cancer, ovarian cancer, and leukemia. Cervical cancer is staged clinically using the International Federation of Gynecology and Obstetrics (FIGO) schema that allows clinical examination, cervical conization or biopsy, plain‐film radiographs, an intravenous pyelogram (IVP), or a barium enema. Pregnant patients generally tolerate surgical procedures well, depending on the nature and complexity of the surgery performed. Moreover, the risks of adverse pregnancy outcomes appear to be small when uncomplicated, non‐emergent surgical procedures are performed. Ultrasound is the preferred study to assess an adnexal mass in pregnancy as it is quite sensitive in detecting features concerning for malignancy. The general emphasis in surgical management should be removal of the mass, and confirmation of the diagnosis with minimal impact on the pregnancy.

Structural Brain Changes after Traditional and Robot-Assisted Multi-Domain Cognitive Training in Community-Dwelling Healthy Elderly
2015
The purpose of this study was to investigate if multi-domain cognitive training, especially robot-assisted training, alters cortical thickness in the brains of elderly participants. A controlled trial was conducted with 85 volunteers without cognitive impairment who were 60 years old or older. Participants were first randomized into two groups. One group consisted of 48 participants who would receive cognitive training and 37 who would not receive training. The cognitive training group was randomly divided into two groups, 24 who received traditional cognitive training and 24 who received robot-assisted cognitive training. The training for both groups consisted of daily 90-min-session, five days a week for a total of 12 weeks. The primary outcome was the changes in cortical thickness. When compared to the control group, both groups who underwent cognitive training demonstrated attenuation of age related cortical thinning in the frontotemporal association cortices. When the robot and the traditional interventions were directly compared, the robot group showed less cortical thinning in the anterior cingulate cortices. Our results suggest that cognitive training can mitigate age-associated structural brain changes in the elderly.

Data from a national study showed that more than one quarter of older adults who died between 2000 and 2006 required decision making at the end of life but lacked decision-making capacity. Most of these subjects had advance directives (living wills, health care proxies, or both) and received care consistent with their preferences. These findings suggest that advance directives are valuable.
