Attitudes, Beliefs, and Intention to Receive a COVID-19 Vaccine for Pediatric Patients With Sickle Cell Disease.

Sickle cell disease (SCD), which occurs primarily in individuals of African descent, has been identified as a preexisting health condition for COVID-19 with higher rates of hospitalization, intensive care unit admissions, and death. National data indicate Black individuals have higher rates of vaccine hesitancy and lower COVID-19 vaccination rates. Understanding the key predictors of intention to receive a COVID-19 vaccine is essential as intention is strongly associated with vaccination behavior. This multisite study examined attitudes, beliefs, intentions to receive COVID-19 vaccines, and educational preferences among adolescents, young adults, and caregivers of children living with SCD. Participants completed an online survey between July 2021 and March 2022. Multivariate logistic regression was used to examine the association between participant age and COVID-19 vaccine attitudes, beliefs, and vaccine intentions. Of the 200 participants, 65.1% of adolescents, 62.5% of young adults, and 48.4% of caregivers intended to receive a COVID-19 vaccine for themselves or their child. Perception that the vaccine was safe was statistically significant and associated with patient and caregiver intention to receive the COVID-19 vaccine for themselves or their child. Participant age was also statistically significant and associated with the intent to get a booster for patients. Study findings highlight key concerns and influencers identified by patients with SCD and their caregivers that are essential for framing COVID-19 vaccine education during clinical encounters. Study results can also inform the design of messaging campaigns for the broader pediatric SCD population and targeted interventions for SCD subpopulations (eg, adolescents, caregivers).

What is the incidence of isolated paraaortic nodal recurrence in grade 1 endometrial carcinoma?

OBJECTIVES: To describe the incidence of isolated paraaortic nodal recurrences in patients with a final diagnosis of grade 1 endometrial carcinoma initially treated with surgery. METHODS: Records from a prospectively maintained endometrial carcinoma database were reviewed to identify sites of recurrence. Patients with any papillary serous or clear cell carcinoma, leiomyosarcoma, endometrial stromal sarcoma, squamous carcinoma, or adenosarcoma were excluded. Recurrence sites were classified into 4 main categories: 1) pelvic (including vaginal and other soft tissue pelvic sites); 2) abdominal (including peritoneum, omentum and liver); 3) distant (including lung, brain, supraclavicular, and groins); and 4) isolated paraaortic nodal recurrence (including any nodal recurrence between the midcommon iliac to renal vessels). RESULTS: Between 1/93 and 5/06, 1453 patients with endometrial carcinoma met the study inclusion criteria. Final grade distribution included: grade 1 endometrial adenocarcinoma, 310 (21%); grade 2, 578 (40%); grade 3, 481 (33%); and incomplete, 84 (5.8%). In all, 154 patients (11%) had documented recurrences. Recurrence sites for all patients/all grades included: pelvis, 52 (34%); abdomen, 51 (33%); distant, 41 (27%), and isolated paraaortic, 10 (6%). None of the isolated paraaortic recurrences occurred in patients with a final diagnosis of grade 1 carcinoma. Furthermore, 9/10 (90%) isolated paraaortic nodal recurrences were in grade 3 tumors. Only 8 (2.6%) of 310 patients with grade 1 tumors recurred. Sites of recurrence for grade 1 tumors included: abdomen, 3; pelvis, 3; and distant, 2. CONCLUSIONS: This large series of endometrial carcinoma patients initially treated with surgery confirms that isolated paraaortic nodal recurrence in women with a final diagnosis of grade 1 endometrial carcinoma is extremely rare. These rare isolated paraaortic nodal recurrences appear to be limited to high-grade endometrial carcinomas.

Is there a therapeutic impact to regional lymphadenectomy in the surgical treatment of endometrial carcinoma?

OBJECTIVE: The objective of the study was to evaluate whether surgical removal of regional lymph nodes influences the overall survival of women with endometrial carcinoma. STUDY DESIGN: All patients with endometrioid-type endometrial cancer treated at our institution between January 1993 and December 2004 were reviewed. The Classification and Regression Tree (CART) method, a form of recursive partitioning, was used. RESULTS: In all, 1035 patients were evaluated. International Federal of Gynecology and Obstetrics stage included the following: stage I, 824; stage II, 65; stage III, 109; and stage IV, 37. Lymph nodes were removed in 524 patients (51%). The median number of nodes removed was 16. Using the CART hierarchically, stage, age, adjuvant therapy, and the removal of 10 lymph nodes or more emerged as predictors of overall survival. CONCLUSION: This study emphasizes the importance of lymph node dissection in endometrial cancer. Lymph node dissection is essential for accurate surgical staging, which remains the most important prognostic factor. In addition to well-known clinicopathologic risk factors for survival, the removal of 10 or more regional lymph nodes was associated with improved overall survival in lower-stage, older patients who received no adjuvant therapy or brachytherapy only.
