RESUMEN

BACKGROUND: Regionalized rectal cancer surgery may decrease postoperative and long-term cancer-related mortality. However, the regionalization of care may be an undue burden on patients. OBJECTIVE: This study aimed to assess the cost-effectiveness of regionalized rectal cancer surgery. DESIGN: Tree-based decision analysis. PATIENTS: Patients with stage II/III rectal cancer anatomically suitable for low anterior resection were included. SETTING: Rectal cancer surgery performed at a high-volume regional center rather than the closest hospital available. MAIN OUTCOME MEASURES: Incremental costs ($) and effectiveness (quality-adjusted life year) reflected a societal perspective and were time-discounted at 3%. Costs and benefits were combined to produce the incremental cost-effectiveness ratio ($ per quality-adjusted life year). Multivariable probabilistic sensitivity analysis modeled uncertainty in probabilities, costs, and effectiveness. RESULTS: Regionalized surgery economically dominated local surgery. Regionalized rectal cancer surgery was both less expensive on average ($50,406 versus $65,430 in present-day costs) and produced better long-term outcomes (10.36 versus 9.51 quality-adjusted life years). The total costs and inconvenience of traveling to a regional high-volume center would need to exceed $15,024 per patient to achieve economic breakeven alone or $112,476 per patient to satisfy conventional cost-effectiveness standards. These results were robust on sensitivity analysis and maintained in 94.6% of scenario testing. LIMITATIONS: Decision analysis models are limited to policy level rather than individualized decision-making. CONCLUSIONS: Regionalized rectal cancer surgery improves clinical outcomes and reduces total societal costs compared to local surgical care. Prescriptive measures and patient inducements may be needed to expand the role of regionalized surgery for rectal cancer. See Video Abstract at http://links.lww.com/DCR/C83 . QU TAN LEJOS ES DEMASIADO LEJOS ANLISIS DE COSTOEFECTIVIDAD DE LA CIRUGA DE CNCER DE RECTO REGIONALIZADO: ANTECEDENTES:La cirugía de cáncer de recto regionalizado puede disminuir la mortalidad posoperatoria y a largo plazo relacionada con el cáncer. Sin embargo, la regionalización de la atención puede ser una carga indebida para los pacientes.OBJETIVO:Evaluar la rentabilidad de la cirugía oncológica de recto regionalizada.DISEÑO:Análisis de decisiones basado en árboles.PACIENTES:Pacientes con cáncer de recto en estadio II/III anatómicamente aptos para resección anterior baja.AJUSTE:Cirugía de cáncer rectal realizada en un centro regional de alto volumen en lugar del hospital más cercano disponible.PRINCIPALES MEDIDAS DE RESULTADO:Los costos incrementales ($) y la efectividad (años de vida ajustados por calidad) reflejaron una perspectiva social y se descontaron en el tiempo al 3%. Los costos y los beneficios se combinaron para producir la relación costo-efectividad incremental ($ por año de vida ajustado por calidad). El análisis de sensibilidad probabilístico multivariable modeló la incertidumbre en las probabilidades, los costos y la efectividad.RESULTADOS:La cirugía regionalizada predominó económicamente la cirugía local. La cirugía de cáncer de recto regionalizado fue menos costosa en promedio ($50 406 versus $65 430 en costos actuales) y produjo mejores resultados a largo plazo (10,36 versus 9,51 años de vida ajustados por calidad). Los costos totales y la inconveniencia de viajar a un centro regional de alto volumen necesitarían superar los $15,024 por paciente para alcanzar el punto de equilibrio económico o $112,476 por paciente para satisfacer los estándares convencionales de rentabilidad. Estos resultados fueron sólidos en el análisis de sensibilidad y se mantuvieron en el 94,6% de las pruebas de escenarios.LIMITACIONES:Los modelos de análisis de decisiones se limitan al nivel de políticas en lugar de la toma de decisiones individualizada.CONCLUSIONES:La cirugía de cáncer de recto regionalizada mejora los resultados clínicos y reduce los costos sociales totales en comparación con la atención quirúrgica local. Es posible que se necesiten medidas prescriptivas e incentivos para los pacientes a fin de ampliar el papel de la cirugía regionalizada para el cáncer de recto.

RESUMEN

BACKGROUND: Routinely obtaining intraoperative cultures for abdominal infections is not a currently recommended evidence-based practice. Yet, cultures are frequently sent from these infections when they are managed by image-guided percutaneous drains. OBJECTIVE: This study aimed to determine the utility of cultures from percutaneously drained intra-abdominal abscesses. DESIGN: Retrospective medical record review. SETTING: Single university-affiliated institution. PATIENTS: Inpatients with an intra-abdominal abscess secondary to diverticulitis or appendicitis between 2013 and 2021 managed with image-guided percutaneous drain, excluding those with active chemotherapy, HIV, or solid organ transplant, were included in the study. MAIN OUTCOME MEASURES: Frequency culture data from percutaneous drains changed antimicrobial therapy. RESULTS: There were 221 patients who met the inclusion criteria. Of these, 56% were admitted for diverticulitis and 44% for appendicitis. Patients were 54% female and had a median age of 62 years (range, 18-93), and 14% were active smokers. The median length of hospitalization was 8 days (range, 1-78) and the median antibiotics course was 8 days (range, 1-22). Culture data from percutaneous drains altered antimicrobial therapy in 8% of patients (16/211). A culture was obtained from 95% of drains, with 78% of cultures with growth. Cultures grew multiple bacteria in 66% and mixed variety without speciation in 13%. The most common pathogen was the Bacteroides family at 33% of all bacteria. The most common empiric antibiotic regimens were ceftriaxone used in 33% of patients and metronidazole used in 40% of patients. Female sex ( p = 0.027) and presence of bacteria with any antibiotic resistance ( p < 0.01) were associated with higher likelihood of cultures influencing antimicrobial therapy. LIMITATIONS: Retrospective and single institution's microbiome. CONCLUSIONS: Microbiology data from image-guided percutaneous drains of abdominal abscesses altered antimicrobial therapy in 8% of patients, which is lower than reported in previously published literature on cultures obtained surgically. Given this low rate, similar to the recommendation regarding cultures obtained intraoperatively, routinely culturing material from drains placed in abdominal abscesses is not recommended.

LOS CULTIVOS DE ABSCESOS INTRA ABDOMINALES DRENADOS PERCUTNEAMENTE CAMBIAN EL TRATAMIENTO UNA REVISIN RETROSPECTIVA: ANTECEDENTES:La obtención rutinaria de cultivos intra-operatorios para infecciones abdominales no es una práctica basada en evidencia actualmente recomendada. Sin embargo, con frecuencia se envían cultivos de estas infecciones cuando se manejan con drenajes percutáneos guiados por imágenes.OBJETIVO:Determinar la utilidad de los cultivos de abscesos intra-abdominales drenados percutáneamente.DISEÑO:Revisión retrospectiva de gráficos.ESCENARIO:Institución única afiliada a la universidad.PACIENTES:Pacientes hospitalizados con absceso intra-abdominal secundario a diverticulitis o apendicitis entre 2013 y 2021 manejados con drenaje percutáneo guiado por imagen, excluyendo aquellos con quimioterapia activa, VIH o trasplante de órgano sólido.PRINCIPALES MEDIDAS DE RESULTADO:Los datos de cultivo de frecuencia de los drenajes percutáneos cambiaron la terapia antimicrobiana.RESULTADOS:Hubo 221 pacientes que cumplieron con los criterios de inclusión. De estos, el 56% ingresaron por diverticulitis y el 44% por apendicitis. El 54% de los pacientes eran mujeres, tenían una edad media de 62 años (18-93) y el 14% eran fumadores activos. La duración de hospitalización media fue de 8 días (rango, 1-78) y la mediana del curso de antibióticos fue de 8 días (rango, 1-22). Los datos de cultivo de drenajes percutáneos alteraron la terapia antimicrobiana en el 7% (16/221) de los pacientes. Se obtuvo cultivo del 95% de los drenajes, con un 79% de cultivos con crecimiento. Los cultivos produjeron múltiples bacterias en el 63% y variedad mixta sin especiación en el 13%. El patógeno más común fue la familia Bacteroides con un 33% de todas las bacterias. El régimen de antibiótico empírico más común fue ceftriaxona y metronidazol, utilizados en el 33% y el 40% de los pacientes, respectivamente. El sexo femenino ( p = 0,027) y la presencia de bacterias con alguna resistencia a los antibióticos ( p < 0,01) se asociaron con una mayor probabilidad de que los cultivos influyeran en la terapia antimicrobiana.LIMITACIONES:Microbioma retrospectivo y de una sola institución.CONCLUSIONES:Los datos microbiológicos de los drenajes percutáneos guiados por imágenes de los abscesos abdominales alteraron la terapia antimicrobiana en el 7% de los pacientes, que es inferior a la literatura publicada previamente sobre cultivos obtenidos quirúrgicamente. Dada esta baja tasa, similar a la recomendación sobre cultivos obtenidos intraoperatoriamente, no se recomienda el cultivo rutinario de material de drenajes colocados en abscesos abdominales.

RESUMEN

INTRODUCTION: Starting in 2021, Centers for Medicare and Medicaid Services required hospitals to provide pricing information to allow consumers to compare prices. Patients perceived that the quality of these services also impacts decision-making. This study examines the relationship between procedure price and quality from the patients' perspective. MATERIALS AND METHODS: Unnegotiated prices of procedures were extracted from hospital websites. Hospital quality was defined as the U.S. News & World Report's score for the specialty performing the procedure. Regional differences in markets were corrected with the Wage Price Index. Spearman's correlations were used for analysis between price and quality. RESULTS: Overall, 67% (1225/1815) of hospitals had a pricing document. Compliance by procedure was poor with a low of 7% for Current Procedural Terminology (CPT) 93000 and a high of 27% for CPTs 93452 and 62323. Wide variability of prices for all procedures was noted. The smallest difference in price range listed was for CPT 45380 with a 32× difference between the minimum and maximum ($310-$10,023) with the first, second, and third quartiles being $1457, $2759, and $4276, respectively. The largest difference in price range was for CPT 55700 with a 5036× difference between the minimum and maximum ($9-$45,322) with the first, second, and third quartiles being $1638, $2971, and $5342, respectively. Correlation between price and quality was low, with the strongest being rho = 0.369 (P = 0.02) for CPT 93000. CONCLUSIONS: Compliance with price transparency was low with large variability in prices for the same procedure. There was no correlation between hospital price and quality. As currently implemented, poor compliance and wide price variability may limit patients' understanding of procedure costs.

RESUMEN

OBJECTIVE: To investigate the occurrence, nature, and reporting of sexual harassment in surgical training and to understand why surgical trainees who experience harassment might not report it. This information will inform ways to overcome barriers to reporting sexual harassment. SUMMARY/ BACKGROUND DATA: Sexual harassment in the workplace is a known phenomenon with reports of high frequency in the medical field. Aspects of surgical training leave trainees especially vulnerable to harassing behavior. The characteristics of sexual harassment and reasons for its underreporting have yet to be studied on the national level in this population. METHODS: An electronic anonymous survey was distributed to general surgery trainees in participating program; all general surgery training programs nationally were invited to participate. RESULTS: Sixteen general surgery training programs participated, yielding 270 completed surveys (response rate of 30%). Overall, 48.9% of all respondents and 70.8% of female respondents experienced at least 1 form of sexual harassment during their training. Of the respondents who experienced sexual harassment, 7.6% reported the incident. The most common cited reasons for nonreporting were believing that the action was harmless (62.1%) and believing reporting would be a waste of time (47.7%). CONCLUSION: Sexual harassment occurs in surgical training and is rarely reported. Many residents who are harassed question if the behavior they experienced was harassment or feel that reporting would be ineffectual-leading to frequent nonreporting. Surgical training programs should provide all-level education on sexual harassment and delineate the best mechanism for resident reporting of sexual harassment.

RESUMEN

Corticosteroid-refractory graft-versus-host disease (SR-GVHD) remains a significant source of morbidity after allogeneic hematopoietic cell transplantation. No standard therapy exists in this setting; however, recent studies have demonstrated a very promising role for ruxolitinib, an oral Janus kinase 1/2 inhibitor. With increasing evidence of efficacy for SR-GVHD, limited data exist describing complications of ruxolitinib use, specifically infectious complications during use in SR-GVHD. In this study we report outcomes and infectious complications at our institution with ruxolitinib use. Overall, 43 patients were treated with ruxolitinib for SR-GVHD, 19 for acute SR-GVHD and 24 for chronic SR-GVHD. With respect to acute SR-GVHD, 15 patients had grade III acute GVHD and 4 patients had grade IV acute GVHD. At 28 days, a response rate of 84% was detected. With respect to chronic SR-GVHD, 16 patients had moderate refractory disease and 8 had severe refractory disease. At around 28 days, a 63% response rate was detected. Overall, 42% of patients (n = 18) treated with ruxolitinib had a documented infectious event. Infectious events were significantly more common among patients treated for acute SR-GVHD (P < .005). Among patients treated for acute SR-GVHD, both viral (n = 11) and bacterial (n = 10) events were frequently encountered. Cytomegalovirus reactivation was detected in 4 patients without organ involvement in any patient. Bacteremia was the most common bacterial event (n = 8), and 2 patients died after development of bacteremia. Only 5 of 24 patients treated with ruxolitinib for chronic SR-GVHD developed infectious complications after initiation of therapy. Nearly an even number of viral (n = 3) and bacterial (n = 4) were detected. This study supports the use of ruxolitinib in SR-GVHD, with impressive responses observed in both acute and chronic SR-GVHD. Infectious complications were particularly frequent among patients treated for acute SR-GVHD, and nearly all these patients were concurrently on high-dose steroids while on ruxolitinib. This study suggests careful monitoring for viral reactivation is required for patients initiated on ruxolitinib, supports the role of continuing prophylactic antimicrobial measures in ruxolitinib-treated GVHD patients, and raises the question of whether bacterial prophylaxis should be considered among patients initiated on ruxolitinib for acute SR-GVHD, particularly while on high-dose steroids.

RESUMEN

The development of reduced-intensity approaches for allogeneic hematopoietic cell transplantation has resulted in growing numbers of older related donors (RDs) of peripheral blood stem cells (PBSCs). The effects of age on donation efficacy, toxicity, and long-term recovery in RDs are poorly understood. To address this we analyzed hematologic variables, pain, donation-related symptoms, and recovery in 1211 PBSC RDs aged 18 to 79 enrolled in the Related Donor Safety Study. RDs aged > 60 had a lower median CD34+ level before apheresis compared with younger RDs (age > 60, 59 × 106/L; age 41 to 60, 81 × 106/L; age 18 to 40, 121 × 106/L; P < .001). This resulted in older donors undergoing more apheresis procedures (49% versus 30% ≥ 2 collections, P < .001) and higher collection volumes (52% versus 32% > 24 L, P < .001), leading to high percentages of donors aged > 60 with postcollection thrombocytopenia <50 × 109/L (26% and 57% after 2 and 3days of collection, respectively). RDs aged 18 to 40 had a higher risk of grades 2 to 4 pain and symptoms pericollection, but donors over age 40 had more persistent pain at 1, 6, and 12 months (odds ratio [OR], 1.7; P = 0.02) and a higher rate of nonrecovery to predonation levels (OR, 1.7; P = .01). Donors reporting comorbidities increased significantly with age, and those with comorbidities that would have led to deferral by National Marrow Donor Program unrelated donor standards had an increased risk for persistent grades 2 to 4 pain (OR, 2.41; P < .001) and failure to recover to predonation baseline for other symptoms (OR, 2.34; P = .004). This information should be used in counseling RDs regarding risk and can assist in developing practice approaches aimed at improving the RD experience for high-risk individuals.

RESUMEN

Unlike unrelated donor registries, transplant centers lack uniform approaches to related donor assessment and deferral. To test whether related donors are at increased risk for donation-related toxicities, we conducted a prospective observational trial of 11,942 related and unrelated donors aged 18-60 years. Bone marrow (BM) was collected at 37 transplant and 78 National Marrow Donor Program centers, and peripheral blood stem cells (PBSC) were collected at 42 transplant and 87 unrelated donor centers in North America. Possible presence of medical comorbidities was verified prior to donation, and standardized pain and toxicity measures were assessed pre-donation, peri-donation, and one year following. Multivariate analyses showed similar experiences for BM collection in related and unrelated donors; however, related stem cell donors had increased risk of moderate [odds ratios (ORs) 1.42; P<0.001] and severe (OR 8.91; P<0.001) pain and toxicities (OR 1.84; P<0.001) with collection. Related stem cell donors were at increased risk of persistent toxicities (OR 1.56; P=0.021) and non-recovery from pain (OR 1.42; P=0.001) at one year. Related donors with more significant comorbidities were at especially high risk for grade 2-4 pain (OR 3.43; P<0.001) and non-recovery from toxicities (OR 3.71; P<0.001) at one year. Related donors with more significant comorbidities were at especially high risk for grade 2-4 pain (OR 3.43; P<0.001) and non-recovery from toxicities (OR 3.71; P<0.001) at one year. Related donors reporting grade ≥2 pain had significant decreases in Health-Related Quality of Life (HR-QoL) scores at one month and one year post donation (P=0.004). In conclusion, related PBSC donors with comorbidities are at increased risk for pain, toxicity, and non-recovery at one year after donation. Risk profiles described in this study should be used for donor education, planning studies to improve the related donor experience, and decisions regarding donor deferral.

RESUMEN

PURPOSE: To evaluate the treatment of autologous serum eye drops (ASED) on dry eyes in patients with graft-versus-host disease (GVHD). METHODS: A retrospective chart review of 35 patients with a history of ocular GVHD following hematopoietic stem cell transplantation that used ASED to alleviate dry eye symptoms was performed. Patients were categorized into three different groups. If patients had available ophthalmic data before and after starting treatment was group 1 (n = 14), had available ophthalmic data after starting treatment in group 2 (n = 10) and had available ophthalmic data before treatment or did not have any data after starting treatment in group 3 (n = 11). Data were collected on patient's age, gender, primary diagnosis, visual acuity and fluorescein corneal staining were collected on individual eyes in order to evaluate the efficacy of the ASED on alleviating dry eye-related signs and symptoms. RESULTS: No adverse ocular effect from the ASED was found in our series (except one fungal keratitis). All patients reported either improvement (55%) or stability (45%) in their ocular symptoms upon the use of ASED. In patients with available data before and after starting treatment, the corneal staining score improved by a median of 1 (p = 0.003) and the LogMAR visual acuity had a non-significant improvement. CONCLUSION: In our study, ASED used by patients with ocular GVHD were both safe and effective. ASED should be considered in patients with GVHD who suffer from dry eyes.

RESUMEN

Allogeneic (allo) hematopoietic cell transplantation (HCT) can induce long-term remissions in chemosensitive relapsed follicular lymphoma (FL). The Blood and Marrow Transplant Clinical Trials Network conducted a multicenter phase 2 trial to examine the efficacy of alloHCT using reduced-intensity conditioning with rituximab (RTX) in multiply relapsed, chemosensitive FL. The primary endpoint was 2-year progression-free survival (PFS). The conditioning regimen consisted of fludarabine, cyclophosphamide, and high-dose RTX (FCR), in which 3 of the 4 doses of RTX were administered at a dose of 1 gm/m(2). Graft-versus-host disease (GVHD) prophylaxis was with tacrolimus and methotrexate. Sixty-five patients were enrolled and 62 were evaluable. Median age was 55 years (range, 29 to 74). This group was heavily pretreated: 77% had received ≥ 3 prior regimens, 32% had received ≥ 5 prior regimens, and 11% had received prior autologous HCT. Donors were HLA-matched siblings (n = 33) or HLA-matched unrelated adults (n = 29). No graft failures occurred. The overall response rate after HCT was 94% with 90% in complete remission (CR), including 24 patients not in CR before alloHCT. With a median follow-up of 47 months (range, 30 to 73), 3-year PFS and overall survival rates were 71% (95% confidence interval, 58% to 81%) and 82% (95% confidence interval, 70% to 90%), respectively. Three-year cumulative incidences of relapse/progression and nonrelapse mortality were 13% and 16%, respectively. Two-year cumulative incidences of grades 2 to 4 and grades 3 or 4 acute GVHD were 27% and 10%, respectively, and extensive chronic GVHD incidence was 55%. Serum RTX concentrations peaked at day +28 and remained detectable as late as 1 year in 59% of patients with available data. In conclusion, alloHCT with FCR conditioning confers high CR rates, a low incidence of relapse/progression, and excellent survival probabilities in heavily pretreated FL patients.

RESUMEN

Guidelines for diverticular disease management were last supported and published by the American Gastroenterology Association and the American College of Gastroenterology 2 decades ago. Guidelines have been published in other countries and by some societies. These guidelines are suggested as United States of America guidelines. In reality, they are what is practiced in Connecticut at Yale New Haven hospitals. The epidemiology and pathophysiology is described. This is still considered a dietary fiber-deficiency disease that results in high intracolonic pressure with resultant outpocketing of diverticula in the weakest point of the colon at the sites of vascular penetration with developing elastin deposition in the colon wall. The age and gender distribution is described. They are most common in the sigmoid. The guidelines of management are described according to accepted classification of the disease at all stages from onset, to early formation, to mild disease, to complicated disease, to rare specific states. The outcomes and mortality are discussed.

RESUMEN

BACKGROUND: Attitudes, career goals, and educational experiences of general surgery residents are profiled during the acquisition of a community residency program by an academic residency program. MATERIALS AND METHODS: The study population included all general surgery residents postgraduate years 2-5 in a tertiary academic medical center divided into community program matriculants (CPM) or academic program matriculants (APM). A survey compared perceptions before and after residency amalgamation in seven training categories as follows: relationships among residents, relationships with faculty, systems interactions, clinical training, surgical training, scholarship, and career plans. Responses were recorded on a Likert scale. Fisher exact test and one-sided t-test were applied. RESULTS: Thirty-five trainees (83%) participated, 23 APM (66%) and 12 CPM (34%). Neither cohort reported significant negative perceptions regarding surgical training, career planning, or scholarship (P > 0.05). There was a greater likelihood of significant negative perceptions regarding inter-resident relationships among CPM (P < 0.05). CPM perceived significantly improved opportunities for scholarship (P < 0.01) and nationwide networking through faculty (P < 0.05) after acquisition. There was a nearly significant trend toward CPM perceiving greater access to competitive specialties after acquisition. Overall, CPM perceptions were affected more often after acquisition; however, when affected, APM were less likely to be positively affected (odds ratio, 2.9). CONCLUSIONS: Acquisition of a community surgery residency by an academic program does not seem to negatively affect trainees' perceptions regarding training. The effect of such acquisition on CPMs' decision to pursue competitive fellowships remains ill defined, but CPM perceived improved research opportunities, faculty networking, and programmatic support to pursue a career in academic surgery.

Ashley W. Oughterson, MD, (1895-1956) was a longtime faculty surgeon at Yale University. He performed some of the earliest pancreatic resections in the United States. During World War II, Colonel Oughterson was the primary "Surgical Consultant" in the South Pacific and present at nearly every major battle. His meticulously kept diary is regarded as the foremost source detailing wartime surgical care. Colonel Oughterson led the initial Army team to survey Hiroshima and Nagasaki following the nuclear attacks. Thoughout his academic career at Yale, Oughterson was a key leader in several medical and surgical societies. As scientific director of the American Cancer Society, Oughterson lectured widely and guided research priorities in oncology following World War II. Oughterson also authored numerous benchmark papers in surgical oncology that continue to be cited today. These extensive contributions are examined here and demonstrate the wide-ranging impact Oughterson exerted during a formative period of American surgery.

RESUMEN

BACKGROUND: General surgical training has changed significantly over the last decade with work hour restrictions, increasing subspecialization, the expanding use of minimally invasive techniques, and nonoperative management for solid organ trauma. Given these changes, this study was undertaken to assess the confidence of graduating general surgery residents in performing open surgical operations and to determine factors associated with increased confidence. METHODS: A survey was developed and sent to general surgery residents nationally. We queried them regarding demographics and program characteristics, asked them to rate their confidence (rated 1-5 on a Likert scale) in performing open surgical procedures and compared those who indicated confidence with those who did not. RESULTS: We received 653 responses from the fifth year (postgraduate year 5) surgical residents: 69% male, 68% from university programs, and 51% from programs affiliated with a Veterans Affairs hospital; 22% from small programs, 34% from medium programs, and 44% from large programs. Anticipated postresidency operative confidence was 72%. More than 25% of residents reported a lack of confidence in performing eight of the 13 operations they were queried about. Training at a university program, a large program, dedicated research years, future fellowship plans, and training at a program that performed a large percentage of operations laparoscopically was associated with decreased confidence in performing a number of open surgical procedures. Increased surgical volume was associated with increased operative confidence. Confidence in performing open surgery also varied regionally. CONCLUSIONS: Graduating surgical residents indicated a significant lack of confidence in performing a variety of open surgical procedures. This decreased confidence was associated with age, operative volume as well as type, and location of training program. Analyzing and addressing this confidence deficit merits further study.

RESUMEN

Increased anorectal human papillomavirus (HPV) infection is related to the recent trends in sexual behavior in both homosexual and heterosexual groups and prevalence of infection with human immunodeficiency virus (HIV). Clinical presentation and natural history depend on the serotype involved. HPV 6 and 11 are found in the benign wart. Local control can be achieved with a wide selection of surgical and topical techniques. HPV 16, 18, and 31 are found in dysplastic lesions and have the potential to progress to invasive anal squamous cell carcinoma. Recognition and early management of dysplastic lesions is crucial to prevent the morbidity and mortality associated with anal cancer. While low-grade lesions can be closely observed, high-grade lesions should be eradicated. Different strategies can be used to eradicate the disease while preserving anorectal function. Studies on the efficacy of vaccination on anorectal HPV showed promising results in select population groups and led to the recent expansion of current vaccination recommendations.

RESUMEN

The mortality due to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) approaches 40% in recipients of chimeric antigen receptor (CAR) T cell therapy (CAR-T). The efficacy of repeated vaccine doses, including bivalent boosters, remains unknown. We examined the efficacy of repeated vaccine doses among CAR-T recipients who received at least 2 or more vaccine doses after T cell infusion. This single-center retrospective study included adults age >18 years receiving CAR-T for relapsed/refractory (R/R) B cell hematologic malignancies targeting CD19, BCMA, or CD19 and CD20 between September 2018 through March 2022 and were alive beyond 2021 to receive incremental SARS-CoV-2 vaccine doses with available seroconversion data. Multivariable analyses were performed using the design-adjusted Cox regression and logistic regression approaches with stratification. In multivariable analysis, seroconversion rates were significantly greater with a total of 4 or more vaccine doses (odds ratio [OR], 8.22; P = .008). CAR-T recipients with other B cell hematologic malignancies had significantly lower seroconversion rates and diminished Ab titers compared to those with R/R multiple myeloma (OR, .07; P = .003). One patient died due to COVID-19 in this vaccinated study cohort, accounting for a COVID-19-attributable mortality rate of 1.7%. The results provide baseline vaccine response data in a contemporary cohort including patients with diverse group of SARS-COV2 variants and support the latest Centers for Disease Control and Prevention guidelines for repeated vaccinations directed against the prevalent variant of concern.

RESUMEN

Recent studies demonstrating the feasibility of outpatient chimeric antigen receptor modified (CAR) T-cell therapy administration are either restricted to CARs with 41BB costimulatory domains or employ intensive at-home monitoring. We report outcomes of outpatient administration of all commercially available CD19- and BCMA-directed CAR-T therapy using a strategy of no remote at-home monitoring and an early cytokine release syndrome (CRS) intervention strategy. Patients with hematologic malignancies who received CAR T-cell therapy in the outpatient setting during 2022-23 were included. Patients were seen daily in the cancer center day hospital for the first 7-10 days and then twice weekly through day 30. The primary endpoint was to determine 3-, 7- and 30-day post CAR T-cell infusion hospitalizations. Early CRS intervention involved administering tocilizumab as an outpatient for grade ≥1 CRS. 58 patients received outpatient CAR T-cell infusion (33 myeloma, 24 lymphoma and 1 acute lymphoblastic leukemia). Of these, 17 (41%), 16 (38%), and 9 (21%) patients were admitted between days 0-3, 4-7 and 8-30 post-CAR T-cell infusion, respectively. The most common reason for admission was CAR T-cell-related toxicities (33/42). Hospitalization was prevented in 15 out of 35 patients who received tocilizumab for CRS as an outpatient. The non-relapse mortality rates were 1.7% at 1 month and 3.4% at 6 months. In conclusion, we demonstrate that the administration of commercial CAR T-cell therapies in an outpatient setting is safe and feasible without intensive remote monitoring employing an early CRS intervention strategy.
