RESUMEN

Locally advanced cutaneous squamous cell carcinoma can erode into blood vessels, leading to vascular blowout, requiring emergent surgical intervention. We describe a first case of this disease complication which was effectively managed with endovascular stenting as a bridge to effective systemic and regional therapy. We discuss the efficacy of this staged approach which is novel and timely in a clinical environment of increasingly effective systemic therapies.

RESUMEN

OBJECTIVE: To determine the feasibility and impact of neoadjuvant therapy (NT) in patients who present with advanced melanoma amenable to surgical resection. SUMMARY BACKGROUND DATA: Given current effective systemic therapy for melanoma, the use of NT is being explored in patients with advanced melanoma with disease amenable to surgical resection. METHODS: Prospective data from 3 institutions was obtained in patients with clinically evident Stage III/IV melanoma who underwent NT. The primary objective was to compare recurrence-free survival between patients who had pathologic complete response (pCR) to those with persistent disease. RESULTS: NT was offered to 45 patients, with 43 patients initiating various NT regimens including PD-1 antagonist (PD-1) therapy (N = 16), PD-1 plus ipilimumab (N = 10), BRAF/MEK inhibitor therapy (N = 14), a combination of those three (N = 1), and talimogene laherparepvec (TVEC) (N = 2). Thirty-two (74.1%) patients underwent surgery whereas 11 patients did not undergo surgery for these reasons: clinical CR (N = 7), progressive disease not amenable to resection (N = 3), and ongoing therapy (N = 1). 12 of 32 patients (37.5%) had pCR with these therapies: PD-1 (N = 4), PD-1 plus ipilimumab (N = 2), BRAF/MEK (N = 4), combination (N = 1), and TVEC (N = 1). At median follow-up of 16.4 months there was only 1 recurrence in the pCR group and patients with a pCR had significantly improved recurrence-free survival compared to patients without pCR (p = 0.004). CONCLUSIONS: Despite variability in NT regimens across institutions, NT for melanoma is feasible and associated with improved prognosis in patients who achieve a pCR. Maximizing rates of pCR could improve prognosis for patients with advanced melanoma.

RESUMEN

BACKGROUND: The optimal time to initiate adjuvant immune checkpoint inhibitors (ICI) following resection remains undefined. Herein, we investigated the impact of time to adjuvant ICI on survival in patients with stage III melanoma. METHODS: Patients with resected stage III melanoma receiving adjuvant immune therapy were identified within a multi-institutional retrospective cohort. Patients were stratified by time to adjuvant ICI: within 6 weeks, 6-12 weeks, and greater than 12 weeks from surgery. Recurrence-free survival (RFS) was compared among time strata with Kaplan-Meier and Cox proportional hazards methods in the multi-institutional cohort. RESULTS: Altogether, 626 patients were identified within the multi-institutional cohort: 39% of patients initiated adjuvant ICI within 6 weeks, 42.2% within 6-12 weeks, and 18.8% greater than 12 weeks from surgery. In a multivariate Cox model, adjusting for histology, nodal tumor burden, and pathologic stage, we found that increased time to adjuvant ICI was associated with improved RFS. Patients who initiated adjuvant ICI within 6 weeks of surgery had worse RFS. These findings were preserved in a conditional landmark analysis and separate subgroups of patients with (1) new melanoma diagnoses, (2) occult stage III disease, and (3) those receiving anti-PD-1 monotherapy. CONCLUSIONS: Outcomes for patients with stage III melanoma are not compromised when adjuvant ICI is initiated beyond 6 weeks from resection. Additional work is needed to better understand the underlying mechanisms and implications of timing of adjuvant ICI on long-term outcomes.

RESUMEN

BACKGROUND: In 2014, technetium-99m tilmanocept (TcTM) replaced technetium-99m sulfur colloid (TcSC) as the standard lymphoscintigraphy (LS) mapping agent in melanoma patients undergoing sentinel lymph node biopsy (SLNB). The aim of this study was to examine differences in mapping time, intra-operative identification of sentinel lymph node (SLN), and false negative rate (FNR) between patients who underwent SLNB with TcTM compared to TcSC. METHODS: Patients who underwent SLNB between 2010 and 2018 were retrospectively identified. Patient demographic, tumor, and imaging data was stratified by receipt of TcSC (n = 258) or TcTM (n = 133). Student's t test and χ2 test were used to compare characteristics and outcomes. RESULTS: Both cohorts were similar in demographic, primary tumor characteristics, and total number of SLN identified (TcTM 3.56 vs. TcSC 3.28, p = 0.244). TcTM was associated with significantly shorter LS mapping times (51.8 vs. 195.1 min, p < 0.01). There was no significant difference in the number of patients with positive SLN (TcTM 11.3 vs. TcSC 17.4%, p = 0.109) and the FNR was similar between both groups (TcTM 25% vs. TcSC 22%). CONCLUSION: TcTM was associated with significantly shorter LS mapping time while identifying similar numbers of SLN. Our results support further study to ensure similar FNR and oncologic outcomes between agents.

RESUMEN

Esophageal cancer is one of the most common cancer killers in our country. The effects of racial disparities on care for esophageal cancer patients are incompletely understood. Using the National Cancer Database, we investigated racial disparities in treatment and outcome of esophageal cancer patients. The National Cancer Database was queried from 2004 to 2017. Logistic regression and survival analysis were used to determine racial differences in access, treatment and outcome. A total of 127,098 patients were included. All minority groups were more likely to be diagnosed at advanced stages versus Caucasians after adjusting for covariates (African American OR-1.64 [95% confidence interval 1.53-1.76], Hispanic OR-1.19 [1.08-1.32], Asian OR-1.78 [1.55-2.06]). After adjustment, all minorities were less likely at every stage to receive surgery. Despite these disparities, Hispanics and Asians had improved survival compared with Caucasians. African Americans had worse survival. Racial disparities for receiving surgery were present in both academic and community institutions, and at high-volume and low-volume institutions. Surgery partially mediated the survival difference between African Americans and Caucasians (HR-1.13 [1.10-1.16] and HR-1.04 [1.02-1.07], without and with adjustment of surgery).There are racial disparities in the treatment of esophageal cancer. Despite these disparities, Hispanics and Asians have improved overall survival versus Caucasians. African Americans have the worst overall survival. Racial disparities likely affect outcome in esophageal cancer. But other factors, such as epigenetics and tumor biology, may correlate more strongly with outcome for patients with esophageal cancer.

RESUMEN

OBJECTIVE: To assess whether a quality improvement bundle focusing on prevention is effective in reducing pressure injury (PI) incidence or costs or delaying PI onset. METHODS: A combined retrospective/prospective cohort study was performed at an academic tertiary care ICU on all patients admitted with a length of stay longer than 48 hours and Braden scale score of 18 or less. Following retrospective data collection (preintervention), a multimodal quality improvement bundle focusing on PI prevention through leadership initiatives, visual tools, and staff/patient education was developed, and data were prospectively collected (postintervention). RESULTS: Statistical and cost analyses were performed comparing both cohorts. A total of 930 patients met the study inclusion criteria (preintervention, n = 599; postintervention, n = 331). A significant decrease in PI incidence was observed from preintervention (n = 37 [6%]) to postintervention (n = 7 [2%], P = .005). This led to a predicted yearly cost savings of $826,810. Further, a significant increase in time to PI occurrence was observed from preintervention (mean, 5 days) to postintervention (mean, 9 days; P = .04). Staff were compliant with the bundle implementation 80% of the time. CONCLUSIONS: Implementation of the quality improvement bundle focused on multimodal PI prevention in critically ill patients led to a significant reduction in PI incidence, increased time to PI occurrence, and was cost-effective.

RESUMEN

OBJECTIVE: To identify subgroups of hormone receptor-positive (HR+) breast cancer patients that might not benefit from adding endocrine therapy (ET) to their local treatment. BACKGROUND: De-escalation in breast cancer treatment has included surgery, radiation, and chemotherapy and has often focused on older patient populations. Systemic ET has yet to be de-escalated, though it carries serious side-effects, decreasing quality of life over 5 to 10 years. We hypothesize the 21-gene recurrence score (RS) could identify subgroups of younger patients whose long-term survival is unaffected by adjuvant ET. METHODS: The National Cancer Database was used to identify women aged ≥50, with HR+, HER2-negative tumors, ≤3 cm in size, N0 status, and a RS≤25, who underwent breast-conserving surgery in 2010 to 2016. Kaplan-Meier and Cox proportional hazards models were used to identify association between treatment and overall survival (OS). RESULTS: Of the 45,217 patients identified, 80.6% were 50 to 69 years old. 42,632 (94.3%) patients received ET and 2585 (5.7%) did not. The 5-year OS was 96.4% for patients receiving ET and 93.1% for those who did not (P < 0.001). After adjusting for all covariates, patients aged 50 to 69 with RS < 11 showed no statistically significant improvement in OS when adding ET to surgery, with or without radiation (P = 0.40). With RS 11 to 25, there was a significant improvement of OS with ET plus radiation (P < 0.001). CONCLUSIONS: Local treatment only, with de-escalation of long-term ET, for patients aged 50 to 69 with RS < 11, seems not to impact OS and should have an anticipated quality of life improvement. Prospective studies investigating this approach are warranted.

RESUMEN

BACKGROUND: In melanoma patients, microscopic tumor in the sentinel lymph-node biopsy (SLN) increases the risk of distant metastases, but the transition from tumor in the SLN to metastatic disease remains poorly understood. METHODS: Fluorescent staining for CD3, CD20, CD11c, and DNA was performed on SLN tissue and matching primary tumors. Regions of interest (ROI) were then chosen geometrically (e.g., tumor) or by fluorescent cell subset markers (e.g., CD11c). Each ROI was further analyzed using NanoString Digital Spatial Profiling high-resolution multiplex profiling. Digital counts for 59-panel immune-related proteins were collected and normalized to account for system variation and ROI area. RESULTS: Tumor regions of SLNs had variable infiltration of CD3 cells among patients. The patient with overall survival (OS) > 8 years had the most CD11c- and CD3-expressing cells infiltrating the SLN tumor region. All patients had CD11c (dendritic cell, DC) infiltration into the SLN tumor region. Selecting ROI by specific cell subtype, we compared protein expression of CD11c cells between tumor and non-tumor/normal tissue SLN regions. Known markers of DC activation such as CD86, HLA-DR, and OX40L were lowest on CD11c cells within SLN tumor for the patient with OS < 1 year and highest on the patient with OS > 8 years. CONCLUSION: We demonstrate the feasibility of profiling the protein expression of CD11c cells within the SLN tumor. Identifying early regulators of melanoma control when the disease is microscopically detected in the SLN is beneficial and requires follow-up studies in a larger cohort of patients.

RESUMEN

BACKGROUND: Although sentinel lymph node (SLN) biopsy is a standard procedure used to identify patients at risk for melanoma recurrence, it fails to risk-stratify certain patients accurately. Because processes in SLNs regulate anti-tumor immune responses, the authors hypothesized that SLN gene expression may be used for risk stratification. METHODS: The Nanostring nCounter PanCancer Immune Profiling Panel was used to quantify expression of 730 immune-related genes in 60 SLN specimens (31 positive [pSLNs], 29 negative [nSLNs]) from a retrospective melanoma cohort. A multivariate prediction model for recurrence-free survival (RFS) was created by applying stepwise variable selection to Cox regression models. Risk scores calculated on the basis of the model were used to stratify patients into low- and high-risk groups. The predictive power of the model was assessed using the Kaplan-Meier and log-rank tests. RESULTS: During a median follow-up period of 6.3 years, 20 patients (33.3%) experienced recurrence (pSLN, 45.2% [14/31] vs nSLN, 20.7% [6/29]; p = 0.0445). A fitted Cox regression model incorporating 12 genes accurately predicted RFS (C-index, 0.9919). Improved RFS was associated with increased expression of TIGIT (p = 0.0326), an immune checkpoint, and decreased expression of CXCL16 (p = 0.0273), a cytokine important in promoting dendritic and T cell interactions. Independent of SLN status, the model in this study was able to stratify patients into cohorts at high and low risk for recurrence (p < 0.001, log-rank). CONCLUSIONS: Expression profiles of the SLN gene are associated with melanoma recurrence and may be able to identify patients as high or low risk regardless of SLN status, potentially enhancing patient selection for adjuvant therapy.

RESUMEN

OBJECTIVE: Older patients diagnosed with cancer are at increased risk of physical and emotional distress; however, prescription utilization patterns largely remain to be elucidated. Our objective was to comprehensively assess prescription patterns and predictors in older patients with bladder cancer. METHODS: A total of 10,516 older patients diagnosed with clinical stage T1-T4a, N0, M0 bladder urothelial carcinoma from 1 January 2008 to 31 December 2012 from the Surveillance, Epidemiology, and End Results (SEER)-Medicare were analyzed. We used multivariable analysis to determine predictors associated with psychotropic prescription rates (one or more). Medication possession ratio (MPR) was used as an index to measure adherence in intervals of 3 months, 6 months, 1 year, and 2 years. Evaluation of psychotropic prescribing patterns and adherence across different drugs and demographic factors was done. RESULTS: Of the 10,516 older patients, 5621 (53%) were prescribed psychotropic drugs following cancer diagnosis. Overall, 3972 (38%) patients had previous psychotropic prescriptions prior to cancer diagnosis, and these patients were much more likely to receive a post-cancer diagnosis prescription. Prescription rates for psychotropic medications were higher among patients with higher stage BC (p < 0.001). Gamma aminobutyric acid modulators/stimulators and serotonin reuptake inhibitors/stimulators were the highest prescribed psychotropic drugs in 21% of all patients. Adherence for all drugs was 32% at 3 months and continued to decrease over time. CONCLUSION: Over half of the patients received psychotropic prescriptions within 2 years of their cancer diagnosis. Given the chronicity of psychiatric disorders with observed significantly low adherence to medications that warrants an emphasis on prolonged patient monitoring and further investigation.

RESUMEN

BACKGROUND: General Surgery residencies use protected education time in various fashions in order to optimize content quality and yield for their learners. This knowledge is tested annually with the American Board for Surgery In-Training Examination (ABSITE) exam and is used to evaluate several aspects of a resident. We hypothesized that using a jeopardy game in educational conference would encourage residents to engage in self-learning and improve ABSITE scores at a single institution. MATERIALS AND METHODS: At a single institution, during protected education conference, residents played an hour-long surgical jeopardy game every 7 wk to summarize high yield topics discussed during the previous 6 wk of didactic learning. A 5-point Likert survey was completed by general surgery residents to discern the utility of the game format for learning. The ABSITE category scores were also evaluated from the year before and the year after the game was implemented. RESULTS: Twenty-four general surgery residents took the survey with >80% agreeing that the jeopardy format was either a fun or an effective way to learn general surgery topics. Additionally, over 80% of residents thought the game format helped with retention of knowledge. ABSITE categories that had a jeopardy session improved from 65.9% to 70.4% correct (P = 0.0003). ABSITE categories that did not have dedicated jeopardy had a non-significant increase in scores (67.7%-69.9%, P = 0.1). CONCLUSIONS: Implementing surgical jeopardy as a component of educational conferences in general surgery resident training is correlated with improvement of ABSITE scores. Surgical jeopardy may be easily adopted and implemented to stimulate self-directed learning for residents.

RESUMEN

BACKGROUND: Multiple adjuvant therapies for melanoma have been approved since 2015 based on randomized trials demonstrating improvements in recurrence-free survival (RFS) with adjuvant therapy after surgical resection of high-risk disease. Inclusion criteria for these trials required performance of a completion lymph node dissection (CLND) for positive sentinel lymph node (pSLN) disease. OBJECTIVE: We aimed to describe current practice for adjuvant therapies in patients with pSLN without CLND (active surveillance [AS]), and to evaluate recurrence in these patients. METHODS: Melanoma patients with pSLN between 2016 and 2019 were identified at two institutions. Demographic information, disease and treatment characteristics, and recurrence details were reviewed retrospectively. Patients were stratified by recurrence and patient-, treatment- and tumor-related characteristics were compared using Fisher's exact test and t test for categorical and continuous variables, respectively. RESULTS: Overall, 245 SLN biopsies were performed, of which 36 (14.7%) were pSLN. Of 36 pSLN, 4 underwent CLND and 32 underwent AS, of whom 22 (68.8%) received adjuvant therapy with the anti-programmed death-1 (PD1) inhibitor nivolumab (16/22), anti-cytotoxic T-lymphocyte-associated protein 4 (CTLA-4) inhibitor ipilimumab (3/22), or BRAF/MEK inhibitors (3/22). At a median follow up of 13.3 months, 7/32 (21.9%) patients on AS recurred, including 4/22 (18.2%) who received adjuvant therapy and 3/10 (30.0%) who did not. Tumor ulceration was significantly associated with recurrence. While not significant, acral lentiginous subtype appeared more common among those with recurrence. CONCLUSION: The majority (68.8%) of patients with pSLN managed without CLND were treated with adjuvant therapy. The 1-year RFS for patients managed with adjuvant therapy without CLND was 82%, which is similar to modern adjuvant therapy trials requiring CLND.

RESUMEN

BACKGROUND: The global pandemic of respiratory disease cause by the novel human coronavirus (SARS-CoV-2) has caused untold suffering, loss of life and upheaval in society. The pandemic has lead to massive redirection of health care resources to treat the surge of COVID-19 patients, and enforcement of social distancing to reduce the rate of transmission. METHODS: Editorial Board members provided observations of the implications of the pandemic on academic surgical oncology. RESULTS: Delivery of health care to other populations including cancer patients has been significantly disrupted. The implications both short term and long term threaten preservation of the academic mission in medicine at large, and certainly in the field of surgical oncology. CONCLUSIONS: The effects on surgical oncology training, research and clinical trials are major.

RESUMEN

BACKGROUND: Isolated limb infusion (ILI) is a minimally invasive procedure for delivering high-dose chemotherapy to extremities affected by locally advanced or in-transit melanoma. This study compared the outcomes of melanoma patients treated with ILI in the United States of America (USA) and Australia (AUS). METHODS: Patients with locally recurrent in-transit melanoma treated with ILI at USA or AUS centers between 1992 and 2018 were identified. Demographic and clinicopathologic characteristics were collected. Primary outcomes of treatment response, in-field progression-free survival (IPFS), distant progression-free survival (DPFS), and overall survival (OS) were evaluated by the Kaplan-Meier method. Multivariable analysis evaluated whether availability of new systemic therapies affected outcomes. RESULTS: More ILIs were performed in AUS (n = 411, 60 %) than in the USA (n = 276, 40 %). In AUS, more ILIs were performed for stage 3B disease than in the USA (62 % vs 46 %; p < 0.001). The reported complete response rates were similar (AUS 30 % vs USA 29 %). Among the stage 3B patients, AUS patients had better IPFS (p = 0.001), whereas DPFS and OS were similar between the two countries. Among the stage 3C patients, the USA patients had better OS (p < 0.001), whereas IPFS and DPFS were similar. Availability of new systemic therapies did not affect IPFS or DPFS in either country. However, the USA patients who received ILI after ipilimumab approval in 2011 had significantly improved OS (hazard ratio, 0.62; p = 0.013). CONCLUSIONS: AUS patients were treated at an earlier disease stage than the USA patients with better IPFS for stage 3B disease. The USA patients treated after the availability of new systemic therapies had a better OS.

RESUMEN

BACKGROUND: Isolated limb infusion (ILI) is used to treat in-transit melanoma metastases confined to an extremity. However, little is known about its safety and efficacy in octogenarians and nonagenarians (ON). PATIENTS AND METHODS: ON patients (≥ 80 years) who underwent a first ILI for American Joint Committee on Cancer seventh edition stage IIIB/IIIC melanoma between 1992 and 2018 at nine international centers were included and compared with younger patients (< 80 years). A cytotoxic drug combination of melphalan and actinomycin-D was used. RESULTS: Of the 687 patients undergoing a first ILI, 160 were ON patients (median age 84 years; range 80-100 years). Compared with the younger cohort (n = 527; median age 67 years; range 29-79 years), ON patients were more frequently female (70.0% vs. 56.9%; p = 0.003), had more stage IIIB disease (63.8 vs. 53.3%; p = 0.02), and underwent more upper limb ILIs (16.9% vs. 9.5%; p = 0.009). ON patients experienced similar Wieberdink limb toxicity grades III/IV (25.0% vs. 29.2%; p = 0.45). No toxicity-related limb amputations were performed. Overall response for ON patients was 67.3%, versus 64.6% for younger patients (p = 0.53). Median in-field progression-free survival was 9 months for both groups (p = 0.88). Median distant progression-free survival was 36 versus 23 months (p = 0.16), overall survival was 29 versus 40 months (p < 0.0001), and melanoma-specific survival was 46 versus 78 months (p = 0.0007) for ON patients compared with younger patients, respectively. CONCLUSIONS: ILI in ON patients is safe and effective with similar response and regional control rates compared with younger patients. However, overall and melanoma-specific survival are shorter.

RESUMEN

BACKGROUND: Isolated limb infusion (ILI) is a minimally invasive procedure for delivering high-dose regional chemotherapy to patients with locally advanced or in-transit melanoma located on a limb. The current international multicenter study evaluated the perioperative and long-term oncologic outcomes for patients who underwent ILI for stage 3B or 3C melanoma. METHODS: Patients undergoing a first-time ILI for stage 3B or 3C melanoma (American Joint Committee on Cancer [AJCC] 7th ed) between 1992 and 2018 at five Australian and four United States of America (USA) tertiary referral centers were identified. The primary outcome measures included treatment response, in-field (IPFS) and distant progression-free survival (DPFS), and overall survival (OS). RESULTS: A total of 687 first-time ILIs were performed (stage 3B: n = 383, 56%; stage 3C; n = 304, 44%). Significant limb toxicity (Wieberdink grade 4) developed in 27 patients (3.9%). No amputations (grade 5) were performed. The overall response rate was 64.1% (complete response [CR], 28.9%; partial response [PR], 35.2%). Stable disease (SD) occurred in 14.5% and progressive disease (PD) in 19.8% of the patients. The median follow-up period was 47 months, with a median OS of 38.2 months. When stratified by response, the patients with a CR or PR had a significantly longer median IPFS (21.9 vs 3.0 months; p < 0.0001), DPFS (53.6 vs 12.7 months; p < 0.0001), and OS (46.5 vs 24.4 months; p < 0.0001) than the nonresponders (SD + PD). CONCLUSION: This study is the largest to date reporting long-term outcomes of ILI for locoregionally metastatic melanoma. The findings demonstrate that ILI is effective and safe for patients with stage 3B or 3C melanoma confined to a limb. A favorable response to ILI is associated with significantly longer IFPS, DPFS, and OS.

RESUMEN

BACKGROUND: Identification of successful general surgical residents remains a challenging endeavor for program directors with a national attrition of approximately 20% per year. The Big 5 personality traits and the Grit Scale have been extensively studied in many industries, and certain traits are associated with professional or academic success. However, their utility in surgery resident selection is unknown. METHODS: We performed a retrospective review of all categorical surgery residents (n = 34) at the University of Texas Medical Branch from 2015 to 2017. Current residents were classified into low performing (n = 12) or non-low performing (n = 22) based on residency performance and standardized test scores. Groups were assessed for differences in both conventional metrics used for selection and Big 5 and grit scores using bivariate analysis and Pearson's correlation coefficient. Personality testing was administered to recent resident applicants (n = 81). Applicants were ranked using conventional application information. We then examined the applicants' personalities and their rank position with personality characteristics of non-low-performing residents to determine if there was any correlation. RESULTS: The Big 5 personality test identified significantly higher extroversion, conscientiousness, and emotional stability scores in those residents classified as non-low performers. There was no significant difference in conventional metrics or in grit scores between non-low performers and low performers. Our final rank does not correlate well with personality traits of non-low performers. CONCLUSIONS: The Big 5 test may prove to be a useful adjunct to the traditional residency application in identifying applicants who may become successful in general surgery residency.

RESUMEN

BACKGROUND AND OBJECTIVES: Reimbursement for colonic pathology by the Centers for Medicare and Medicaid Services (CMS) are grouped in the Medicare Severity-Diagnosis Related Groups (MS-DRG). With limited available data, we sought to compare the relative impact of malignant vs benign colonic pathology on reimbursement under the MS-DRG system. METHODS: We used 5% national Medicare data from 2011 to 2014. Patients were classified as having benign disease or malignancy. Descriptive statistics and multivariate regression analysis were used to evaluate the surgical approach and health resource utilization. RESULTS: Of 10 928 patients, most were Non-Hispanic White women. The majority underwent open colectomy in both cohorts (P < .001). Colectomy for benign disease was associated with higher total charges (P < .001) and a longer length of stay (P = .0002). Despite higher charges, payments were not significantly different between the cohorts (P = .434). Both inpatient mortality and discharge to a rehab facility were higher in the oncologic group (P < .001). CONCLUSION: Payment methodology for colectomy under the CMS MS-DRG system does not appear to accurately reflect the episode cost of care. The data suggest that inpatient costs are not fully compensated. A transition to value-based payments with expanded episode duration will require a better understanding of unique costs before adoption.

RESUMEN

BACKGROUND: Treatments for muscle-invasive bladder cancer are multimodal, complex, and often carry significant risks of physical and psychological morbidity. The objectives of this study were to define the incidence and types of psychiatric illnesses diagnosed after treatment and to determine their impact on survival outcomes. METHODS: In total, 3709 patients who were diagnosed with clinical stage T2 through T4a bladder cancer from January 1, 2002, to December 31, 2011, from the Surveillance, Epidemiology, and End Results-Medicare were analyzed. Multivariable analysis and Cox proportional-hazards models were used to determine the predictors associated with psychiatric diagnosis and impact on survival outcomes. RESULTS: Of 3709 patients, 1870 (50.4%) were diagnosed with posttreatment psychiatric disorders. Patients who underwent radical cystectomy were identified as being at significantly greater risk of having a posttreatment psychiatric illness compared with those who received radiotherapy and/or chemotherapy (hazard ratio [HR], 1.19; 95% confidence interval [CI], 1.07-1.31; P = .001). In adjusted analyses, diagnosis of a psychiatric disorder resulted in significantly worse overall survival (HR, 2.80; 95% CI, 2.47-3.17; P < .001) and cancer-specific survival (HR, 2.39; 95% CI, 2.05-2.78; P < .001). CONCLUSIONS: One-half of patients with muscle-invasive bladder cancer who underwent treatment were diagnosed with a psychiatric disorder, which resulted in worse survival outcomes compared with patients who did not have a posttreatment psychiatric diagnosis. This information can be used to inform interventions to educate patients with muscle-invasive bladder cancer regarding the impact of different treatments on mental health.
