RESUMO

BACKGROUND: Golidocitinib, a selective JAK1 tyrosine-kinase inhibitor, has shown encouraging anti-tumour activity in heavily pre-treated patients with relapsed or refractory peripheral T-cell lymphoma in a phase 1 study (JACKPOT8 Part A). Here, we report the full analysis of a phase 2 study, in which we assessed the anti-tumour activity of golidocitinib in a large multinational cohort of patients. METHODS: We did a single-arm, multinational, phase 2 trial (JACKPOT8 Part B) in 49 centres in Australia, China, South Korea, and the USA. Eligible patients were adults (aged ≥18 years) with relapsed or refractory peripheral T-cell lymphoma who had received at least one previous line of systemic therapy and an Eastern Cooperative Oncology Group performance status of 0-2. Patients were given oral golidocitinib 150 mg once daily until disease progression or other discontinuation criteria were met. The primary endpoint was the CT-based objective response rate, assessed by an independent review committee (IRC) per Lugano 2014 classification. The activity analysis set included all patients who received at least one dose and whose pathological diagnosis of peripheral T-cell lymphoma had been retrospectively confirmed by a central laboratory and who had at least one measurable lesion at baseline assessed by IRC. The safety analysis set included all patients who received at least one dose of study drug. This study is registered with ClinicalTrials.gov, NCT04105010, and is closed to accrual and follow-up is ongoing. FINDINGS: Between Feb 26, 2021, and Oct 12, 2022, we assessed 161 patients for eligibility, of whom 104 (65%) were enrolled and received at least one dose of study drug; the activity analysis set included 88 (85%) patients (median age 58 years [IQR 51-67], 57 [65%] of 88 were male, 31 [35%] were female, and 83 [94%] were Asian). As of data cutoff (Aug 31, 2023; median follow-up was 13·3 months [IQR 4·9-18·4]), per IRC assessment, the objective response rate was 44·3% (95% CI 33·7-55·3; 39 of 88 patients, p<0·0001), with 21 (24%) patients having a complete response and 18 (20%) having a partial response. In the safety analysis set, 61 (59%) of 104 patients had grade 3-4 drug-related treatment-emergent adverse events. The most common grade 3-4 drug-related treatment-emergent adverse events were neutrophil count decreased (30 [29%]), white blood cell count decreased (27 [26%]), lymphocyte count decreased (22 [21%]), and platelet count decreased (21 [20%]), which were clinically manageable and reversible. 25 (24%) patients had treatment-related serious adverse events. Deaths due to treatment-emergent adverse events occurred in three (3%) patients: two (2%) due to pneumonia (one case with fungal infection [related to golidocitinib] and another one with COVID-19 infection) and one (1%) due to confusional state. INTERPRETATION: In this phase 2 study, golidocitinib showed a favourable benefit-risk profile in treating relapsed or refractory peripheral T-cell lymphoma. The results of this study warrant further randomised clinical studies to confirm activity and assess efficacy in this population. FUNDING: Dizal Pharmaceutical.

RESUMO

Patients with relapsed/refractory (R/R) transformed diffuse large B-cell lymphoma (DLBCL) from indolent B-cell lymphomas, including Richter transformation (RT), have a poor prognosis. PD-1/PD-L1 antibodies produce modest objective and complete response rates (ORR and CRR) in B-NHL as monotherapy but may synergize with immunogenic chemotherapies like gemcitabine and oxaliplatin (GemOx). Thus, we evaluated the safety and efficacy of atezolizumab plus rituximab and GemOx (R-GemOx+Atezo) in R/R transformed DLBCL, including RT. We conducted a phase I trial including patients with transformed DLBCL after ≥1 prior therapy. Patients received up to 4 cycles of R-GemOx-+Atezo. Patients in CR could then proceed to Ratezo maintenance until progression. A safety lead-in with dose-limiting toxicity (DLT) evaluation was enrolled to confirm the recommended phase 2 dose (RP2D), followed by 2 expansion cohorts: one for transformed follicular lymphoma (FL) and another for non-FL transformed DLBCL, including RT. Twenty-seven patients were enrolled. One of the 6 safety lead-in patients had a DLT attributed to atezolizumab, a grade 4 Stevens-Johnson syndrome (SJS). The most common grade ≥3 events were neutropenia (18.5%), lymphopenia (18.5%), and thrombocytopenia (14.8%). The overall and complete response rates (ORR and CRR) were 59% and 33%, respectively. The ORR and CRR in transformed FL were 79% and 43%, and 38% and 23% in transformed non-FL, respectively. The median PFS and OS of the total population were 4.2 and 7.7 months, respectively. R-GemOx+Atezo was well tolerated and demonstrated promising preliminary efficacy in patients with R/R transformed DLBCL.

RESUMO

BACKGROUND: Risk factors for progression to advanced-stage mycosis fungoides (MF) are poorly defined. METHODS: The authors performed a single-center, retrospective cohort study among patients with MF at an academic medical center from 1990 to 2020 to identify clinical variables associated with progression to advanced-stage MF (stage IIB-IVB), and 388 patients who had a clinicopathologic diagnosis of early stage (IA-IIA) MF were identified from their cutaneous lymphoma database. Baseline clinical characteristics, laboratory values, imaging, and blood flow cytometry or T-cell receptor gene rearrangement (TCR) data were collected. Logistic regression was used to assess risk factors associated with progression. RESULTS: Overall, 93 of 388 patients (24.0%) progressed to advanced stage. Patients who progressed had an increased risk of death (hazard ratio, 4.50; 95% CI, 2.89-7.00; p < .001). Progression was associated with a higher overall stage at diagnosis, tumor stage, lymph node stage, low-level blood involvement, as measured with TCR data and/or flow cytometry, and elevated lactate dehydrogenase (LDH). Limitations included missing data for LDH, imaging, peripheral blood TCR data, or flow cytometry assessed at diagnosis. CONCLUSIONS: Staging and baseline laboratory assessments with imaging, peripheral blood flow cytometry, TCR data, and LDH in patients who have newly diagnosed MF may identify those who are at risk for progression to advanced stage.

RESUMO

Pembrolizumab, a humanized IgG4 monoclonal antibody targeting programmed death-1 protein, has demonstrated efficacy in relapsed/refractory classical Hodgkin lymphoma (cHL). To assess the complete metabolic response (CMR) rate and safety of pembrolizumab monotherapy in newly diagnosed cHL, we conducted a multicenter, single-arm, phase 2 investigator-initiated trial of sequential pembrolizumab and doxorubicin, vinblastine, and dacarbazine (AVD) chemotherapy. Patients ≥18 years of age with untreated, early, unfavorable, or advanced-stage disease were eligible for treatment. Thirty patients (early unfavorable stage, n = 12; advanced stage, n = 18) were treated with 3 cycles of pembrolizumab monotherapy followed by AVD for 4 to 6 cycles, depending on stage and bulk. Twelve had either large mediastinal masses or bulky disease (>10 cm). After pembrolizumab monotherapy, 11 patients (37%) demonstrated CMRs, and an additional 7 of 28 (25%) patients with quantifiable positron emission tomography computed tomography scans had >90% reduction in metabolic tumor volume. All patients achieved CMR after 2 cycles of AVD and maintained their responses at the end of treatment. With a median follow-up of 22.5 months (range, 14.2-30.6) there were no changes in therapy, progressions, or deaths. No patients received consolidation radiotherapy, including those with bulky disease. Therapy was well tolerated. The most common immune-related adverse events were grade 1 rash (n = 6) and grade 2 infusion reactions (n = 4). One patient had reversible grade 4 transaminitis and a second had reversible Bell's palsy. Brief pembrolizumab monotherapy followed by AVD was both highly effective and safe in patients with newly diagnosed cHL, including those with bulky disease. This trial was registered at www.clinicaltrials.gov as #NCT03226249.

RESUMO

PURPOSE: WHO grade 4 gliomas are rare in the pediatric and adolescent and young adult (AYA) population. We evaluated prognostic factors and outcomes in the pediatric versus AYA population. METHODS: This retrospective pooled study included patients less than 30 years old (yo) with grade 4 gliomas treated with modern surgery and radiotherapy. Overall survival (OS) and progression-free survival (PFS) were characterized using Kaplan-Meier and Cox regression analysis. RESULTS: Ninety-seven patients met criteria with median age 23.9 yo at diagnosis. Seventy-seven patients were ≥ 15 yo (79%) and 20 patients were < 15 yo (21%). Most had biopsy-proven glioblastoma (91%); the remainder had H3 K27M-altered diffuse midline glioma (DMG; 9%). All patients received surgery and radiotherapy. Median PFS and OS were 20.9 months and 79.4 months, respectively. Gross total resection (GTR) was associated with better PFS in multivariate analysis [HR 2.00 (1.01-3.62), p = 0.023]. Age ≥ 15 yo was associated with improved OS [HR 0.36 (0.16-0.81), p = 0.014] while female gender [HR 2.12 (1.08-4.16), p = 0.03] and DMG histology [HR 2.79 (1.11-7.02), p = 0.029] were associated with worse OS. Only 7% of patients experienced grade 2 toxicity. 62% of patients experienced tumor progression (28% local, 34% distant). Analysis of salvage treatment found that second surgery and systemic therapy significantly improved survival. CONCLUSION: Age is a significant prognostic factor in WHO grade 4 glioma, which may reflect age-related molecular alterations in the tumor. DMG was associated with worse OS than glioblastoma. Reoperation and systemic therapy significantly increased survival after disease progression. Prospective studies in this population are warranted.

RESUMO

Children with sickle cell disease (SCD) frequently present to hospital acutely unwell and are often exposed to diagnostic chest X-rays (CXRs). Little evidence exists to determine when CXRs are clinically useful. Using electronic hospital records, we audited CXR use in children aged 0-18 who presented to hospital over the past 10 years in both an inpatient and emergency department setting. From a total of 915 first CXRs, only 28·2% of CXRs (n = 258) had clinically significant findings that altered management or final diagnosis. Of these abnormalities, consolidation represented 52·3%, effusion 8·9%, cardiomegaly 8·4% and sickle cell-related bone changes 6·3%. Indications for CXR of respiratory distress (OR = 3·74, 95% CI 2·28-6·13), hypoxia (OR = 1·86, 95% CI 1·50-2·31) and cough (OR = 1·64, 95% CI 1·33-2·02), were more likely to have significant CXR findings. Patients who had higher peak fever (38·4°C vs. 37·4°C, P = 0·001), higher peak CRP (156·4 vs. 46·1, P < 0·001) and higher WCC (20·2 vs. 13·6, P < 0·001) were more likely to have clinically significant abnormalities on CXR. We found a decision tool using either hypoxia, cough, respiratory distress, T > 38°C, CRP > 50 or WCC > 15 × 109 /l as indications for CXR, to have a sensitivity of 88% (with 95% CI 0·78-0·95) and specificity of 46% (95% CI 0·43-0·50) for clinically significant findings.

RESUMO

Hepatosplenic T-cell lymphoma (HSTCL) is a rare T-cell neoplasm that most commonly arises from a small subset of γ/δ T-cell receptor-expressing lymphocytes. HSTCL is more common in adolescent and young adults and has a rapidly progressive clinical course and poor outcome due to its refractoriness to conventional chemotherapy regimens. Approximately 20% of the cases arise in the background of chronic immunosuppression or immune dysregulation. Patients commonly present with constitutional symptoms, hepatic and liver enlargement, and cytopenias; hematophagocytic syndrome can also occur. The most frequent chromosomal aberrations associated with HSTCL are isochromosome 7q and trisomy 8, and most cases harbor mutations in genes involved in chromatin modification or the JAK/STAT pathway. The rarity of this disease, along with lack of nodal involvement and presenting symptoms that mimic different entities including infectious etiologies, makes this lymphoma a significant diagnostic challenge. In this review, we highlight the clinical and pathologic features of HSTCL. Moreover, we summarize the results of recent molecular studies suggesting potential targets for novel therapeutics strategies.

RESUMO

BACKGROUND: Palliative radiotherapy (RT) is effective, but some patients die during treatment or too soon afterward to experience benefit. This study investigates end-of-life RT patterns to inform shared decision-making and facilitate treatment consistent with palliative goals. MATERIALS AND METHODS: All patients who died ≤6 months after initiating palliative RT at an academic cancer center between 2015 and 2018 were identified. Associations with time-to-death, early mortality (≤30 days), and midtreatment mortality were analyzed. RESULTS: In total, 1,620 patients died ≤6 months from palliative RT initiation, including 574 (34%) deaths at ≤30 days and 222 (14%) midtreatment. Median survival was 43 days from RT start (95% CI, 41-45) and varied by site (P<.001), ranging from 36 (head and neck) to 53 days (dermal/soft tissue). On multivariable analysis, earlier time-to-death was associated with osseous (hazard ratio [HR], 1.33; P<.001) and head and neck (HR, 1.45; P<.001) sites, multiple RT courses ≤6 months (HR, 1.65; P<.001), and multisite treatments (HR, 1.40; P=.008), whereas stereotactic technique (HR, 0.77; P<.001) and more recent treatment year (HR, 0.82; P<.001) were associated with longer survival. No difference in time to death was noted among patients prescribed conventional RT in 1 to 10 versus >10 fractions (median, 40 vs 47 days; P=.272), although the latter entailed longer courses. The 30-day mortality group included 335 (58%) inpatients, who were 27% more likely to die midtreatment (P=.031). On multivariable analysis, midtreatment mortality among these inpatients was associated with thoracic (odds ratio [OR], 2.95; P=.002) and central nervous system (CNS; OR, 2.44; P=.002) indications, >5-fraction courses (OR, 3.27; P<.001), and performance status of 3 to 4 (OR, 1.63; P=.050). Conversely, palliative/supportive care consultation was associated with decreased midtreatment mortality (OR, 0.60; P=.045). CONCLUSIONS: Earlier referrals and hypofractionated courses (≤5-10 treatments) should be routinely considered for palliative RT indications, given the short life expectancies of patients at this stage in their disease course. Providers should exercise caution for emergent thoracic and CNS indications among inpatients with poor prognoses due to high midtreatment mortality.

RESUMO

BACKGROUND: Cutaneous T-cell lymphoma (CTCL) is a rare form of non-Hodgkin lymphoma arising in the skin. Geographic clustering of CTCL has recently been reported, but its association with environmental factors is unknown. Benzene and trichloroethylene (TCE) are environmental toxins with carcinogenic properties. The authors investigated associations between geographic clustering of CTCL incidence in the state of Georgia with benzene and TCE exposure. METHODS: The statewide county-level incidence of CTCL within Georgia was obtained from the Georgia Cancer Registry for the years 1999 to 2015. Standardized incidence ratios (SIRs) were calculated by dividing observed cases by expected cases using national incidence rates by age, sex, and race. Clustering of CTCL was analyzed using spatial analyses. County-level concentrations of benzene and TCE between 1996 and 2014 were collected from the Environmental Protection Agency's National Air Toxics Assessment database. Linear regression analyses on CTCL incidence were performed comparing SIRs with levels of benzene and TCE by county. RESULTS: There was significant geographic clustering of CTCL in Georgia, particularly around Atlanta, which was correlated with an increased concentration of benzene and TCE exposure. Among the 4 most populous counties in Georgia, CTCL incidence was between 1.2 and 1.9 times higher than the state average, and benzene and TCE levels were between 2.9 and 8.8 times higher. CONCLUSIONS: The current results demonstrate nonrandom geographic clustering of CTCL incidence in Georgia. To the authors' knowledge, this is the first analysis to identify a correlation between geographic clustering of CTCL and environmental toxic exposures.

RESUMO

BACKGROUND: The purpose of this study was to assess treatment choices among men with prostate cancer who presented at The University of Texas MD Anderson Cancer Center multidisciplinary (MultiD) clinic compared with nationwide trends. METHODS: In total, 4451 men with prostate cancer who presented at the MultiD clinic from 2004 to 2016 were analyzed. To assess nationwide trends, the authors analyzed 392,710 men with prostate cancer who were diagnosed between 2004 and 2015 from the Surveillance, Epidemiology, and End Results (SEER) database. The primary endpoint was treatment choice as a function of pretreatment demographics. RESULTS: Univariate analyses revealed similar treatment trends in the MultiD and SEER cohorts. The use of procedural forms of definitive therapy decreased with age, including brachytherapy and prostatectomy (all P < .05). Later year of diagnosis/clinic visit was associated with decreased use of definitive treatments, whereas higher risk grouping was associated with increased use (all P < .001). Patients with low-risk disease treated at the MultiD clinic were more likely to receive nondefinitive therapy than patients in SEER, whereas the opposite trend was observed for patients with high-risk disease, with a substantial portion of high-risk patients in SEER not receiving definitive therapy. In the MultiD clinic, African American men with intermediate-risk and high-risk disease were more likely to receive definitive therapy than white men, but for SEER the opposite was true. CONCLUSIONS: Presentation at a MultiD clinic facilitates the appropriate disposition of patients with low-risk disease to nondefinitive strategies of patients with high-risk disease to definitive treatment, and it may obviate the influence of race.

RESUMO

Adolescents and young adults (AYAs) with cancer constitute approximately 70,000 patients diagnosed each year. Survival rates for AYAs with cancer have increased steadily in recent decades due to improvements in therapeutic regimens and early detection. Given the large and growing number of AYA cancer survivors, additional research is needed on the immediate and long-term psychosocial support required for this population including family planning and fertility. Fertility and fertility preservation in female AYAs, in particular, is historically understudied and has psychologically relevant ramifications distinct from male AYAs. Decision science can contribute to this area of oncological care and has implications for clinical encounters and research concerning female AYA patients with cancer. Patient-centered care and shared decision-making that integrates recent research regarding fertility preservation in the context of cancer.

RESUMO

PURPOSE OF REVIEW: Older patients with diffuse large B-cell lymphoma (DLBCL) may face challenges in treatment due to comorbidities and tolerance of chemotherapy. RECENT FINDINGS: Older patients are at increased risk for treatment-related toxicity if they are unfit or frail by comprehensive geriatric assessment (CGA); however, treatment with non-anthracycline chemotherapy is associated with inferior outcomes in fit and unfit patients. Many older patients remain curable with standard R-CHOP chemotherapy. Careful assessment of frailty, function, and comorbidities using CGA may aid clinicians in initial therapy choices.

RESUMO

PURPOSE OF REVIEW: Peripheral T cell lymphomas (PTCLs) are a heterogeneous group of non-Hodgkin lymphomas with inferior prognosis compared with their B cell counterparts characterized by frequent relapses, resulting in a median 5-year survival of approximately 30%. Their diverse clinicopathologic features challenge existing treatment paradigms that treat all patients uniformly. Here we review recent advances in the treatment of these diseases. RECENT FINDINGS: While current treatment still relies largely on combination chemotherapy, the introduction of more effective novel and targeted therapies has improved outcomes in certain subtypes. Increasing understanding of the underlying biology of PTCL has prompted further subclassification by genetic and molecular subgroups. Overall, the most significant advances in PTCL management have resulted from improved understanding and classification of the biology of PTCL. Ongoing development of subtype-specific targeted therapies will be essential to improve long-term outcomes of patients with these diseases.

RESUMO

OBJECTIVE: To identify the optimal adjuvant treatment regimen for patients with endometrioid and non-endometrioid node-positive endometrial cancer. METHODS: We retrospectively identified 249 women with FIGO 2009 stage IIIC endometrial cancer at our institution who underwent surgical staging from 1985 to 2015 followed by external beam radiotherapy (RT), chemotherapy (CT), or a combination of CT + RT. Survival rates were calculated using the Kaplan-Meier method. RESULTS: The 5-year disease-specific survival (DSS) rate for all patients was 65%. Adjuvant CT + RT conferred higher rates of 5-year DSS as compared to CT alone in patients with grade 3 endometrioid and non-endometrioid tumors (61% vs. 27%, P = 0.04 and 67% vs. 38%, P = 0.02, respectively). Among patients with non-endometrioid tumors, treatment with concurrent chemoradiotherapy followed by additional sequential chemotherapy had higher 5-year DSS rates than with concurrent chemoradiotherapy alone (74% vs. 50%, P = 0.02). The 3-year pelvic recurrence rate was 5% with RT ±â€¯CT and 35% with CT alone (P < 0.001) for all patients. No paraaortic nodal failures were observed following extended-field RT, but 14% of patients who received pelvic-only RT or CT alone developed recurrences in the paraaortic nodes (P < 0.001). CONCLUSIONS: Combined-modality therapy including adjuvant external beam pelvic radiotherapy yields excellent outcomes for patients with all subtypes of node-positive endometrial cancer. The most pronounced DSS advantage from adjuvant chemoradiotherapy was evident in women with non-endometrioid endometrial cancer.

RESUMO

OBJECTIVE: To compare radical prostatectomy (RP) vs radiotherapy (RT) with androgen-deprivation therapy (ADT) in the setting of patients with high-risk and very high-risk (VHR) prostate cancer who were deemed eligible for either therapy and made a treatment choice after consultation in a multidisciplinary prostate cancer clinic (MDPCC), and to compare the MDPCC patients' outcomes to a matched Surveillance, Epidemiology and End Results (SEER) cohort. PATIENTS AND METHODS: Prospectively collected, retrospective study comparing patients who underwent RP (231 patients) vs RT+ADT (73) from 2004 to 2013. Biochemical recurrence (BCR), local recurrence, distant metastasis failure, and overall survival (OS) were calculated for each treatment group overall and according to National Comprehensive Cancer Network risk strata. A propensity score matched comparison with a SEER cohort was performed for OS. RESULTS: There was no difference in local recurrence (hazard ratio [HR] 2.7, 95% confidence interval [CI] 1.0-7.9; P = 0.06), distant metastasis failure (HR 2.5, 95% CI 0.8-7.8; P = 0.1) and OS (HR 1.35, 95% CI 0.4-4.8; P = 0.6) between patients undergoing RP vs RT+ADT. Patients treated via the MDPCC survived on average 16.9 months (95% CI 13.1-20.8) longer than those in the matched SEER cohort. CONCLUSIONS: Long-term outcomes appear similar amongst patients with high-risk and VHR prostate cancer deemed eligible for either RP or RT, and treated after consultation in a MDPCC. Outcomes of the MDPCC patients were superior to those of the matched SEER cohort.

RESUMO

PURPOSE OF REVIEW: Availability of highly effective novel agents has altered the approach to initial therapy in patients with classical Hodgkin lymphoma (cHL). We will review controversies in the following areas: (1) the role of radiation in early unfavorable disease and the optimal treatment strategies for (2) advanced-stage disease and (3) elderly patients. RECENT FINDINGS: Strategies incorporating brentuximab vedotin into frontline treatment of cHL yielded favorable results in non-randomized elderly studies and were compared to ABVD in advanced disease among adults. Meanwhile, four cycles of escalated BEACOPP yielded unprecedented favorable results for the treatment of advanced disease in the German Hodgkin Study Group 18 study. The addition of novel agents to conventional treatment strategies has the potential to improve outcomes in high-risk groups of patients while reducing toxicity. The role of radiation therapy remains in question but may see diminished use with the incorporation of more effective agents in the frontline setting.

RESUMO

To determine whether pre-treatment neutrophil/lymphocyte (NLR) or platelet/lymphocyte ratios (PLR) are predictive for progression in early-stage classical Hodgkin lymphoma (cHL), we derived NLR and PLR values for 338 stage I/II cHL patients and appropriate cut-off point values to define progression. Two-year freedom from progression (FFP) for patients with NLR ≥6·4 was 82·2% vs. 95·7% with NLR <6·4 (P < 0·001). Similarly, 2-year FFP was 84·3% for patients with PLR ≥266·2 vs. 96·1% with PLR <266·2 (P = 0·003). On univariate analysis, both NLR and PLR were significantly associated with worse FFP (P = 0·001). On multivariate analysis, PLR remained a significant, independent prognostic factor (P < 0·001).

RESUMO

BACKGROUND & AIMS: The association between case volume and outcomes is well-documented for several cancer types. However, it is unknown if patients with hepatocellular carcinoma treated at high-volume centres have improved overall survival. METHODS: About 135 442 patients diagnosed with hepatocellular carcinoma between 2004-2014 were identified in the Commission on Cancer's National Cancer Database and 53 795 patients were excluded for metastatic or node-positive disease. Average annual case volume was calculated as the total number of cases treated per centre from 2004-2014 and dividing by 10. Receiver operating characteristic curves showed the most significant case number threshold between high-volume centres and remaining centres. Univariate and multivariate analyses were performed using Cox regression analysis to determine factors associated with improved survival. Kaplan-Meier curves and log-rank tests were used for overall survival estimates. RESULTS: A total of 81 647 patients with stage I-III hepatocellular carcinoma were treated at a total of 1218 centres. The median [range] case volume per year averaged over the 10-year study period was 48.6 [0.1-205.5]. High-volume centres treated >114 cases of hepatocellular carcinoma annually while remaining centre treated ≤114 cases. Median survival for patients treated in high-volume centres and remaining centres were 31.9 and 16.6 months respectively (Log Rank P < .001). On multivariate analysis, average annual case volume was significantly associated with improved survival. CONCLUSIONS: Receiving treatment at a high-volume centre is significantly associated with survival for patients with non-metastatic disease. Improved survival at high-volume centres may be related to access to a variety of treatment modalities, multidisciplinary evaluation, and/or subspecialty expertise.

RESUMO

OBJECTIVES: This study aimed to evaluate the impact of radiation therapy on outcomes for patients with uterine carcinosarcoma (UC). METHODS/MATERIALS: We retrospectively reviewed the records of 155 women with stage I (98), II (11), or III (46) UC who underwent total abdominal hysterectomy/bilateral salpingo-oophorectomy at our institution between 1990 and 2011. Survival rates were assessed using the Kaplan-Meier method and log-rank test. Univariate and multivariate Cox regression analyses were performed. RESULTS: Seventy-six patients (49%) received radiation therapy: 38 (50%) had vaginal cuff brachytherapy (VBT) alone and 38 had external beam radiation therapy (EBRT) ± VBT. Seventy patients (45%) received chemotherapy (12 concurrent, 49 adjuvant, 9 both). The 5-year overall survival rate was 48.6% (stage I, 53.8%; II, 30.0%; and III, 42.5%). The disease-specific survival (DSS) rate was 57.2% (stage I, 60.9%; II, 44.4%; and III, 51.8%). Patients treated with EBRT had a higher 5-year pelvic disease control rate (88.3%) than did patients treated with VBT only (67.4%) or no radiation (71.2%; P = 0.04). In stage III patients, EBRT was associated with higher 5-year pelvic disease control (90.0% vs 55.5%, P = 0.046), DSS (64.6% vs 46.4%, P = 0.13), and overall survival (64.6% vs 34.0%, P = 0.04) rates. For all 155 patients, age at least 65 years, cervical involvement, and lymph vascular space invasion were correlated with lower DSS on univariate and multivariate analyses. In addition, treatment with concurrent chemoradiation therapy was independently associated with a higher DSS rate on multivariate analysis. CONCLUSIONS: Patients with UC have a high rate of relapse in the regional nodes and distant sites. External beam radiation therapy improves locoregional control in all stages and may improve survival in stage III patients who are at the highest risk of pelvic relapse.
