RESUMO

PURPOSE: This study explored the relationship of spirituality and religiosity as it affects the physical and mental quality of life (pQOL, mQOL) of cancer survivors. METHODS: This is a prospective observational study that included adults ≥ 19 years who received treatment for various types of cancer. Patients' QOL was obtained at baseline, 6, and 12 months. Cohorts were categorized according to spirituality/religiosity levels: low spirituality-low religiosity (LSLR), low spirituality-high religiosity (LSHR), high spirituality-low religiosity (HSLR), and high spirituality-high religiosity (HSHR). RESULTS: Of the 551 eligible, 248 (45%) had HSHR, 196 (36%) had LSHR, 75 (14%) had LSLR, and 32 (6%) had HSLR. The pQOL of LSLR were significantly lower than those with HSHR (p = 0.02). The differences in pQOL between LS and HS were observed among those who have HR (p < 0.0001). Among patients with LR, pQOL did not differ. The mQOL of patients with LSLR was significantly lower than those with HSHR (p < 0.0001). The mQOL of those with HS was significantly higher than those with LS in both cohorts having LR (p < 0.0001) or HR (p < 0.0001). pQOL decreased while mQOL increased over time regardless of spirituality or religiosity levels. CONCLUSION: Spirituality is important in the improvement of both pQOL and mQOL of cancer survivors, while religiosity may have some impact on pQOL. Clinicians' incorporation of spirituality into cancer treatment facilitates well-rounded care, which offers measurable improvements for patients with an illness, of which the treatment is often arduous, and uncertain.

RESUMO

BACKGROUND: Gemtuzumab ozogamicin (GO) administered before allogeneic hematopoietic cell transplantation (alloHCT) has been linked to an increased risk of hepatic veno-occlusive disease/sinusoidal obstruction syndrome (VOD/SOS). PROCEDURE: This retrospective analysis examined VOD/SOS risk and clinical outcomes in pediatric patients with acute myeloid leukemia who received myeloablative alloHCT in 2008-2011 with (n = 148) and without (n = 348; controls) prior GO exposure and were reported to the Center for International Blood and Marrow Transplant Research. RESULTS: Cumulative incidences (95% confidence interval [CI]) of VOD/SOS and severe VOD/SOS, respectively, at 100 days were 16% (11-23%) and 8% (4-13%) for GO-exposed patients and 10% (7-13%) and 3% (2-5%) for controls. With a median follow-up of approximately 7 years, the 5-year adjusted overall survival probability (95% CI) after alloHCT was 51% (43-58%) and 55% (50-60%) for GO-exposed patients and controls, respectively; three (4%) and one (<1%) deaths were attributed to VOD/SOS. In multivariate analyses, GO exposure was observed to be associated with an increased risk of VOD/SOS at 100 days, but was not associated with overall survival, disease-free survival, relapse, or nonrelapse mortality. CONCLUSIONS: Results suggest that GO treatment prior to alloHCT in pediatric patients may increase the risk of VOD/SOS but not death.

RESUMO

Gemtuzumab ozogamicin (GO) therapy before allogeneic hematopoietic cell transplantation (alloHCT) has been historically associated with an increased risk of hepatic veno-occlusive disease/sinusoidal obstruction syndrome (VOD/SOS) in patients with acute myeloid leukemia (AML). The current analysis examined VOD/SOS risk and outcomes in a cohort of patients who in recent years were reported to the Center for International Blood and Marrow Transplant Research. Adults with AML who had GO exposure before myeloablative alloHCT were matched 1:4 by age and disease status at transplant to recipients without GO exposure (control subjects). One hundred thirty-seven patients with GO exposure and 548 matched control subjects who underwent alloHCT between 2008 and 2011 were included in this analysis. With a median ∼8-year follow-up of survivors, the 5-year overall survival probability was similar in the 2 cohorts: 38% and 38% in the GO-exposed versus control groups (P = .97). Incidence of VOD/SOS and severe VOD/SOS, respectively, at 100 days was 4% (95% confidence interval [CI], 1% to 7%) and 3% (95% CI, 1% to 6%) in GO-exposed patients and 3% (95% CI, 2% to 5%) and 1% (95% CI, 0% to 2%) in control subjects. Correspondingly, among patients who developed VOD/SOS, 1-year survival probability after VOD/SOS diagnosis was 33% (95% CI, 5% to 72%) and 27% (95% CI, 11% to 47%; P = .78). In multivariate analyses, GO exposure before alloHCT was not associated with an increased risk of VOD/SOS (odds ratio, 1.10; P = .85) or death (hazard ratio, 1.08; P = .57). Three deaths (3%) in the GO group and 3 deaths (<1%) in the control group were attributed to VOD/SOS. Our results suggest that GO treatment before myeloablative alloHCT in the recent era is not associated with an increased risk of post-transplant VOD/SOS or death.

RESUMO

Allogeneic hematopoietic cell transplantation (alloHCT) is a highly specialized procedure. We surveyed adult transplant centers in the United States (US) and then used data reported to the Center for International Blood and Marrow Transplant Research (CIBMTR) (2008-2010) to evaluate associations of center volume, infrastructure, and care delivery models with survival post alloHCT. Based on their 2010 alloHCT volume, centers were categorized as low-volume (≤40 alloHCTs; N = 42 centers, 1900 recipients) or high-volume (>40 alloHCTs; N = 41 centers, 9637 recipients). 100-day survival was 86% (95% CI, 85-87%) in high-volume compared with 83% (95% CI, 81-85%) in low-volume centers (difference 3%; P < 0.001). One-year survival was 62% (95% CI, 61-63%) and 56% (95% CI, 54-58%), respectively (difference 6%; P < 0.001). Logistic regression analyses adjusted for patient and center characteristics; alloHCT at high-volume centers (odds ratio [OR] 1.32; P < 0.001) and presence of a survivorship program dedicated to HCT recipients (OR 1.23; P = 0.009) were associated with favorable 1-year survival compared to low-volume centers. Similar findings were observed in a CIBMTR validation cohort (2012-2014); high-volume centers had better 1-year survival (OR 1.24, P < 0.001). Among US adult transplant centers, alloHCT at high-volume centers and at centers with survivorship programs is associated with higher 1-year survival.

RESUMO

BACKGROUND: Inotuzumab Ozogamicin (INO), has demonstrated an improvement in overall survival, high rate of complete remission, favorable patient-reported outcomes, and manageable safety profile vs standard of care (SoC; intensive chemotherapy) for relapsed/refractory (R/R) acute lymphoblastic leukemia (ALL) in the phase 3 INO-VATE trial. With a one-hour weekly dosing schedule, INO might be associated with lower healthcare system burden. This study analyses hospitalizations for INO vs SoC. METHODS: All patients receiving study treatment in the INO-VATE trial were included. The days hospitalized during study treatment was calculated. Due to different treatment durations for INO and SoC (median of 3 vs 1 cycles), number of hospital days was mainly reported per observed patient month. Hospital days per patient month were analyzed for different treatment cycles, subgroups, and main reasons for hospitalization. Differences between treatments were analyzed by the incidence rate ratio (IRR). RESULTS: Overall, 82.9% and 94.4% INO and SoC patients experienced at least one hospitalization. The mean hospitalization days per patient month was 7.6 and 18.4 days for INO and SoC (IRR = 0.413, P < .001), which corresponds to patients spending 25.0% and 60.5% of their treatment time in a hospital. Main hospitalization reasons were R/R ALL treatment (5.2 (INO) vs 14.0 (SoC) days, IRR = 0.368, P < .001), treatment toxicities (1.4 vs 2.8 days, IRR = 0.516, P < .001) or other reasons (1.0 vs 1.6 days, IRR 0.629, P < .001). CONCLUSIONS: Inotuzumab Ozogamicin treatment in R/R ALL is associated with a lower hospitalization burden compared with SoC. It is likely this lower burden has a favorable impact on healthcare budgets and cost-effectiveness considerations.

RESUMO

Attaining complete remission of acute lymphoblastic leukemia (ALL) before hematopoietic stem cell transplantation (HSCT) correlates with better post-transplant outcomes. Inotuzumab ozogamicin (InO), an anti-CD22 antibody conjugated to calicheamicin, has shown significantly higher rates of remission, minimal residual disease negativity, and HSCT versus standard chemotherapy in treating relapsed/refractory (R/R) ALL. We investigated the role of previous transplant and proceeding directly to HSCT after remission as factors in determining post-transplant survival in the setting of InO treatment for R/R ALL. The analyzed population comprised InO-treated patients who proceeded to allogeneic HSCT in 2 clinical trials (phase 1/2: NCT01363297 and phase 3: NCT01564784). Overall survival (OS) was defined as time from HSCT to death (any cause). Of 236 InO-treated patients, 101 (43%) proceeded to allogeneic HSCT and were included in this analysis. Most received InO as first salvage (62%); 85% had no previous HSCT. Median (95% confidence interval [CI]) post-transplant OS was 9.2 months (5.1, not evaluable) with 2-year survival probability (95% CI) of 41% (32% to 51%). In first-HSCT patients (n = 86), median (95% CI) post-transplant OS was 11.8 months (5.9, not evaluable) with 2-year survival probability (95% CI) of 46% (35% to 56%); some patients relapsed and needed additional treatment before HSCT (n = 28). Those who went directly to first HSCT upon remission with no additional salvage/induction treatment (n = 73) fared best: median post-transplant OS was not reached with a 2-year survival probability (95% CI) of 51% (39% to 62%). In patients with R/R ALL, InO followed by allogeneic HSCT provided an optimal long-term survival benefit among those with no previous HSCT who went directly to transplant after remission.

RESUMO

Primary CNS diffuse large B-cell lymphoma (PCNS-DLBCL) and systemic DLBCL harbor mutations in MYD88 and CD79B. DNA methyltransferase (MGMT) is methylated in some DLBCL. Our goal was to investigate the frequencies of these events, which have not been previously reported within the same series of patients with PCNS-DLBCL. Fifty-four cases of PCNS-DLBCL from two institutions were analyzed by Sanger sequencing for MYD88 and CD79B, and pyrosequencing for MGMT. MYD88 mutations were identified in 68.8% (35 of 51 cases), with L265P being the most frequent mutation. Mutations other than L265P were identified in 21.6% of cases, of which eight novel MYD88 mutations were identified. Of mutated cases, 17.6% had homozygous/hemizygous MYD88 mutations, which has not been previously reported in PCNS-DLBCL. CD79B mutations were found in six of 19 cases (31.6%), all in the Y196 mutation hotspot. MGMT methylation was observed in 37% (20 of 54 cases). There was no significant difference in median overall survival (OS) between the wild type and mutated MYD88 cases, or between methylated and unmethylated MGMT cases. However, a significant difference (P = 0.028) was noted in median OS between the wild type and mutated CD79B cases.

RESUMO

OBJECTIVES: To compare the percentage of patients who had an oral cancer examination (OCE) by their primary care provider (PCP) in medical clinics participating in a web-based education with poster reminder intervention to that of patients in control clinics. To also determine the effects for PCPs in medical clinics participating in the web-based education with poster reminder intervention as compared with those in control clinics regarding: a) index of knowledge of oral cancer risk factors (RiskOC) and b) index of knowledge of oral cancer diagnostic procedures (DiagOC). METHODS: Six medical clinics were recruited to participate in this study and randomly assigned to an intervention group or a control group. PCPs (physicians, physician assistants, and advanced practice registered nurses) took a pretest; 2 weeks later, they participated in the web-based educational program, including a posttest (intervention group) or took a posttest only (control group). In each clinic, 1 week following completion of the PCPs' posttests, 94 patients were recruited to complete a one-page survey. RESULTS: The intervention clinics were found to be a significant factor for the PCPs to perform patient OCEs, after controlling for significant covariates, that is, age, main reason for clinic visit, OCE for patient in the past year, clinic's mean DiagOC score, and clinic's mean RiskOC score. The intervention also resulted in the PCPs increasing their pretest to posttest RiskOC scores. CONCLUSIONS: The use of intervention has the potential to increase PCPs' short-term knowledge and to increase the frequency of PCPs' routine, nonsymptomatic opportunistic OCE on patients.

RESUMO

In the United States, insurance status has been implicated as a barrier to obtaining timely treatment. In this retrospective cohort study of 521 patients who underwent first hematopoietic cell transplantation (HCT), we investigated the association between timeliness of HCT and overall survival. Timeliness was operationally defined in the following 3 ways: (1) payer approval, from request for approval to actual payer approval; (2) transplantation speed, from payer approval to time of actual HCT; and (3) total time, from request for approval to HCT. Patients with private insurance had longer time to payer approval (P < .0001) than those with public payers but shorter time from approval to actual HCT (P < .0001) and total time to HCT (P < .0001). Multivariate Cox regression showed no significant differences in risk of death between slow and fast times in the 3 indices of timeliness in the models that used all patients (n = 509), autologous HCT in lymphoma (n = 278), and autologous HCT in multiple myeloma (n = 121). Additional studies to evaluate the effect of insurance timeliness on all patients for whom HCT is recommended, not just those who undergo HCT, should be conducted.

RESUMO

Regionalization of specialized health services can deliver high-quality care but may have an adverse impact on access and outcomes because of distance from the regional centers. In the case of hematopoietic cell transplantation (HCT), the effect of increased distance between the transplantation center and the rural/urban residence is unclear because of conflicting results from the existing studies. We examined the association between distance from primary residence to the transplantation center and rural versus urban residence with clinical outcomes after allogeneic HCT in a large cohort of patients. Overall mortality (OM), nonrelapse mortality (NRM), and relapse in all patients and those who survived for 200 days after HCT were assessed in 2849 patients who received their first allogeneic HCT between 2000 and 2010 at Fred Hutchinson Cancer Research Center (FHCRC)/Seattle Cancer Care Alliance. Median distance from FHCRC was 263 miles (range, 0 to 2740 miles) and 83% of patients were urban residents. The association between distance and the hazard of OM varied according to conditioning intensity: myeloablative (MA) versus nonmyeloablative (NMA). Among MA patients, there was no evidence of an increased risk of mortality with increased distance, but for NMA patients, the results did show a suggestion of increased risk of mortality for some distances, although globally the difference was not statistically significant. In the subgroup of patients who survived 200 days, there was no evidence that the risks of OM, relapse, or NRM were increased with increasing distance. We did not find any association between longer distance from transplantation center and urban/rural residence and outcomes after MA HCT. In patients undergoing NMA transplantations, this relationship and how it is influenced by factors such as age, payers, and comorbidities needs to be further investigated.

RESUMO

The objective of this retrospective study (N = 169) was to compare the overall survival (OS) of different subtypes of mantle cell lymphoma (MCL) treated by the Nebraska Lymphoma Study Group between 1984 and 2012. The overall response rate to various therapies including stem cell transplant (SCT) was similar (p = 0.44) between blastoid, diffuse and nodular subtypes. At 5 years, blastoid and diffuse subtypes had worse OS (overall p = 0.005) compared to nodular subtype. In multivariate analysis, the blastoid and diffuse subtypes had similar risk of death (p = 0.14) whereas the nodular subtype had a lower risk compared to blastoid (HR 0.48, 95% CI 0.27-0.87, p = 0.01). The use of SCT was associated with lower risk of death. In univariate analysis, blastoid subtype had better OS with intensive upfront therapy. In conclusion, the OS of blastoid subtype is worse than nodular MCL but may improve with the use of SCT and probably intensive induction therapy.

RESUMO

BACKGROUND: Optimal management of locally advanced non-small cell lung cancer (NSCLC) lacks consensus. A retrospective analysis of patient data entered in the Veterans Affairs Central Cancer Registry was conducted to evaluate these issues. PATIENTS AND METHODS: Data of patients with cT1-4, cN2, and cM0 NSCLC diagnosed in the VA Health System between 1995 and 2003 were evaluated. Age, sex, race, smoking history, TNM stage, treatment, and overall survival were abstracted. Survival was compared using multivariate Cox proportional hazards regression analysis. RESULTS: Of the 7328 patients analyzed, 7218 (98.5%) were male, 6061 (82.7%) were white, and 321 (4.4%) were never smokers. The treatment received included: none, 23.8%; chemotherapy alone, 14.3%; radiation alone, 23%; and chemoradiation (sequential or concurrent), 31.4%. Only 7.5% of patients had a surgical resection, with or without multimodality therapy. The median survival (months) of these patient groups were: surgery, 19.3; chemoradiation, 13; chemotherapy alone, 9.2; radiation alone, 7.3; and no treatment, 4 (P<0.0001). African Americans had a significantly decreased risk of mortality compared with whites (hazard ratio 0.92; 95% confidence interval, 0.87-0.98). CONCLUSIONS: Inclusion of surgical resection as a treatment modality was associated with a better overall survival. Also, African Americans appeared to do better than whites. These hypothesis-generating findings should be useful in the ongoing pursuit of better treatment strategies for locally advanced NSCLC.

RESUMO

Peripheral T-cell lymphomas (PTCL) have suboptimal outcomes using conventional CHOP (cyclophosphamide, doxorubicin, vincristine, prednisone) chemotherapy. The anti-folate pralatrexate, the first drug approved for patients with relapsed/refractory PTCL, provided a rationale to incorporate it into the front-line setting. This phase 2 study evaluated a novel front-line combination whereby cyclophosphamide, etoposide, vincristine and prednisone (CEOP) alternated with pralatrexate (CEOP-P) in PTCL. Patients achieving a complete or partial remission (CR/PR) were eligible for consolidative stem cell transplantation (SCT) after 4 cycles. Thirty-three stage II-IV PTCL patients were treated: 21 PTCL-not otherwise specified (64%), 8 angioimmunoblastic T cell lymphoma (24%) and 4 anaplastic large cell lymphoma (12%). The majority (61%) had stage IV disease and 46% were International Prognostic Index high/intermediate or high risk. Grade 3-4 toxicities included anaemia (27%), thrombocytopenia (12%), febrile neutropenia (18%), mucositis (18%), sepsis (15%), increased creatinine (12%) and liver transaminases (12%). Seventeen patients (52%) achieved a CR. The 2-year progression-free survival and overall survival, were 39% (95% confidence interval 21-57) and 60% (95% confidence interval 39-76), respectively. Fifteen patients (45%) (12 CR) received SCT and all remained in CR at a median follow-up of 21·5 months. CEOP-P did not improve outcomes compared to historical data using CHOP. Defining optimal front line therapy in PTCL continues to be a challenge and an unmet need.

RESUMO

BACKGROUND: Central nervous system complications (CNSC) can be the cause of morbidity and mortality in patients undergoing allogeneic hematopoietic stem cell transplantation (allo-HSCT). We aimed to determine the incidence of CNSC and its impact on survival. PATIENTS AND METHODS: This retrospective cohort study included patients with hematologic disorders who received allo-HSCT between 2002 and 2011 at the University of Nebraska Medical Center. RESULTS: Of the 351 patients identified, 45 developed CNSC (12.8%). The 100-day cumulative incidence of CNSC was 8% (95% confidence interval, 8-15). The most common CNSC included posterior reversible encephalopathy syndrome (40%), stroke or transient ischemic attack (24%), seizures (20%), and infection (9%). The 5-year overall survival was significantly lower among patients with versus without CNSC (14% vs. 44%, P = .0004). In multivariate analysis, the risk of mortality for patients with versus without CNSC was significantly higher (hazard ratio, 1.56; 95% confidence interval, 1.03-2.36; P = .04). CONCLUSION: The occurrence of CNSC after allo-HSCT was associated with reduced survival. Identifying patients at risk, monitoring, early detection, and management of CNSC after allo-HSCT are needed to improve outcomes.

RESUMO

The use of large databases has provided advancements in the understanding of racial, ethnic, and socioeconomic disparities in the field of adult hematopoietic cell transplants (HCT). Disparities exist on individual, institutional, and systemic levels for both allogeneic and autologous HCT. We reviewed the most recent publications that utilized large databases to elucidate disparities in HCT and placed them into historical context of the other major studies in the field. Two emerging themes were identified. These themes are persistent inequalities in both allogeneic HCT and autologous HCT for myeloma and the importance of improving homogeneity of care in HCT. Minimization of inequalities can be achieved only with an understanding of the persistent barriers that exist in the field.

RESUMO

Controversy surrounds the question of whether clinical trial participants have better outcomes than comparable patients who are not treated on a trial. We explored this question using a recent large, randomized, multicenter study comparing peripheral blood (PB) with bone marrow transplantation from unrelated donors, conducted by the Blood and Marrow Transplant Clinical Trials Network (BMT CTN). We compared characteristics and outcomes of study participants (n = 494) and nonparticipants (n = 1384) who appeared eligible and received similar treatment without enrolling on the BMT CTN trial at participating centers during the study time period. Data were obtained from the Center for International Blood and Marrow Transplant Research. Outcomes were compared between the 2 groups using Cox proportional hazards regression models. No significant differences in age, sex, disease distribution, race/ethnicity, HLA matching, comorbidities, and interval from diagnosis to hematopoietic cell transplantation were seen between the participants and nonparticipants. Nonparticipants were more likely to have lower performance status, lower risk disease, and older donors, and to receive myeloablative conditioning and antithymocyte globulin. Nonparticipants were also more likely to receive PB grafts, the intervention tested in the trial (66% versus 50%, P < .001). Overall survival, transplantation-related mortality, and incidences of acute or chronic graft-versus-host disease were comparable between the 2 groups though relapse was higher (hazard ratio, 1.22; 95% confidence interval, 1.02 to 1.46; P = .028) in nonparticipants. Despite differences in certain baseline characteristics, survival was comparable between study participants and nonparticipants. The results of the BMT CTN trial appear generalizable to the population of trial-eligible patients.

RESUMO

Hematopoietic cell transplantation (HCT) is a complex procedure that requires availability of adequate infrastructure, personnel, and resources at transplantation centers. We conducted a national survey of transplantation centers in the United States to obtain data on their personnel, infrastructure, and care delivery models. A 42-item web-based survey was administered to medical directors of transplantation centers in the United States that reported any allogeneic HCT to the Center for International Blood and Marrow Transplant Research in 2011. The response rate for the survey was 79% for adult programs (85 of 108 centers) and 82% for pediatric programs (54 of 66 centers). For describing results, we categorized centers into groups with similar volumes based on 2010 total HCT activity (adult centers, 9 categories; pediatric centers, 6 categories). We observed considerable variation in available resources, infrastructure, personnel, and care delivery models among adult and pediatric transplantation centers. Characteristics varied substantially among centers with comparable transplantation volumes. Transplantation centers may find these data helpful in assessing their present capacity and use them to evaluate potential resource needs for personnel, infrastructure, and care delivery and in planning for growth.

RESUMO

BACKGROUND: Understanding the mortality patterns of patients with lymphoma and myeloma, who have undergone autologous hematopoietic stem cell transplantation (ASCT) might identify improvement opportunities. PATIENTS AND METHODS: The present retrospective study included patients with lymphoma and myeloma, aged ≥ 18 years, who had undergone ASCT from 1983 to 2010 at the University of Nebraska Medical Center. Of the 2284 patients, 972 had died within first 5 years after ASCT. The patients were divided into 3 cohorts according to the time of transplantation: 1983 to 1990 (cohort I), 1991 to 2000 (cohort II), and 2001 to 2010 (cohort III). Using Cox proportional hazards regression analysis, the risk of cause-specific mortality was compared across the 3 cohorts. RESULTS: Of a total of 1215 deaths, 972 (80%) occurred within the first 5 years after ASCT. Disease relapse (73.4%), organ failure (7.8%), infection (4.7%), and secondary malignancy (4.2%) accounted for most of the deaths. The risk of death from infection (P < .0001), but not from relapse (P = .26), organ failure (P = .68), or secondary malignancy (P = .15), had declined in the more recent cohorts. CONCLUSION: The 5-year overall survival of patients undergoing ASCT has improved significantly owing to a decline in infectious mortality. Our results highlight that the mortality from relapse remains the most common cause of death, warranting investigation of different strategies to reduce the incidence of relapse and improve the therapy for relapse after ASCT.

RESUMO

The objective of this study was to examine the association between body mass index (BMI) and the incidence of pulmonary complications (PCs) after hematopoietic stem cell transplant (HCT). We reviewed 398 adult patients with non-Hodgkin lymphoma (NHL) who received autologous or allogeneic HCT between 1993 and 1997. BMI was classified as normal (18.5 < BMI ≤ 24.9), overweight (24.9 < BMI ≤ 30) and obese (BMI > 30). Multivariate logistic regression was used to analyze the relationship between BMI and presence of PCs within 100 days post-HCT while adjusting for patient-, disease- and transplant-related variables. The incidence of PCs within 100 days post-HCT was 32% (n = 129). Median BMI was 25.4 (range: 18.6-52.2). Median age was 48.8 years (range: 19.5-73.6 years). Multivariate analysis failed to show significant association between BMI and PCs. However, a total body irradiation (TBI)-based conditioning regimen was associated with lower rate of PCs.

RESUMO

BACKGROUND: The incidence of melanoma in older patients is on the rise. Prior studies have shown disparities in surgical management and poor survival of older patients with melanoma. METHODS: This is a retrospective study of adult patients diagnosed with cutaneous invasive and in situ melanoma between 2000 and 2011 in the National Cancer Data Base. Characteristics and management of older patients (≥60 years) were compared with younger patients (20-59 years) using χ(2) testing. RESULTS: Of 476,623 total cases, 54% (n = 258,153) were diagnosed among older patients. The reported cases in the older patients increased by 1.74-fold between 2000 and 2011. The majority were white (96%), men (65%), with early-stage disease (76% stage 0-II), and superficial spreading melanoma histology (39%). Older patients, compared with younger patients, were more likely to be men (65% versus 49%, p < 0.0001), and have in situ melanoma (28% versus 21%, p < 0.0001); less likely to have nodal metastases (7% versus 9%, p < 0.0001), receive care in academic centers (30% versus 35%, p < 0.0001), undergo wide excision or major amputation for stage I-III disease (68% versus 72%, p < 0.0001) and systemic therapy for stage III (18% versus 45%, p < 0.0001) and IV disease (30% versus 50%, p < 0.0001). CONCLUSION: Older patients with melanoma are less likely to receive care in academic centers, undergo wide excision for stage I-III disease and receive systemic therapy for stage III-IV disease. Particularly, the utilization of systemic therapy is markedly low. This disparity is particularly important with the availability of less intense more effective therapies.
