Differences In Prognostic Factors Research Articles

Factors affecting the long-term prognosis of patients in the AYA generation with epithelial ovarian cancer: A multicenter propensity score matching analysis.

Ovarian carcinoma (OvCa) is more common in the elderly, but also affects the adolescent and young adult (AYA) generation, which refers to those aged 15-39 years. Although the characteristics of OvCa may differ between AYAs and non-AYAs, limited information is currently available on differences in prognostic factors. Therefore, we herein investigated prognostic factors for and the prognosis of OvCa in AYAs. We also examined the prognostic impact of fertility-sparing surgery in a subgroup analysis. We retrospectively collected data on 4897 patients with OvCa from the databases of multiple institutions and ultimately included 1161 patients with epithelial ovarian cancer (EOC). We performed a survival analysis to compare AYAs and non-AYAs with backgrounds that conformed to those of AYAs using the propensity score (PS) matching method. A Cox regression analysis was also conducted to evaluate each predictor of recurrence-free survival (RFS) and overall survival (OS) in the original population. As a subgroup analysis, a multivariate analysis stratified by the AYA and non-AYA generations was performed. In total, 119 AYA patients were included in this study. After PS adjustments, no significant differences were observed in RFS or OS between AYAs and non-AYAs. Prognostic factors differed between AYAs and non-AYAs, particularly in histology and cytology. A multivariate analysis stratified by the AYA and non-AYA generations described that uterine-preserving surgery (UPS) did not have a significant impact on the prognosis of AYAs or non-AYAs. In cases with recurrence, no significant differences were observed in RFS and recurrent sites in the two groups. Characteristic prognostic factors for EOC in AYAs were identified. The present results indicate the limited prognostic impact of UPS for EOC in AYAs.

Sex-Based Analysis of Workflow and Outcomes in Acute Ischemic Stroke Patients Treated With Alteplase Versus Tenecteplase.

Understanding sex differences in stroke care is important in reducing potential disparities. Our objective was to explore sex differences in workflow efficiency, treatment efficacy, and safety in the AcT trial (Alteplase Compared to Tenecteplase). AcT was a multicenter, registry-linked randomized noninferiority trial comparing tenecteplase (0.25 mg/kg) with alteplase (0.9 mg/kg) in acute ischemic stroke within 4.5 hours of onset. In this post hoc analysis, baseline characteristics, workflow times, successful reperfusion (extended Thrombolysis in Cerebral Infarction score ≥2b), symptomatic intracerebral hemorrhage, 90-day functional independence (modified Rankin Scale score, 0-1), and 90-day mortality were compared by sex. Mixed-effects regression analysis was used adjusting for age, stroke severity, and occlusion site for outcomes. Of 1577 patients treated with intravenous thrombolysis (2019-2022), 755 (47.9%) were women. Women were older (median, 77 [68-86] years in women versus 70 [59-79] years in men) and had a higher proportion of severe strokes (National Institutes of Health Stroke Scale score >15; 32.4% versus 24.9%) and large vessel occlusions (28.7% versus 21.5%) compared with men. All workflow times were comparable between sexes. Women were less likely to achieve functional independence (31.7% versus 39.8%; unadjusted relative risk, 0.80 [95% CI, 0.70-0.91]) and had higher mortality (17.7% versus 13.3%; unadjusted relative risk, 1.33 [95% CI, 1.06-1.69]). Adjusted analysis showed no difference in outcomes between sexes. Differences in prognostic factors of age, stroke severity, and occlusion site largely accounted for higher functional dependence and mortality in women. No sex disparities were apparent in workflow quality indicators. Given the integration of the AcT trial into clinical practice, these results provide reassurance that no major sex biases are apparent in acute stroke management throughout participating Canadian centers.

Red Blood Cell Transfusion Independence Status Is an Independent Predictor of Survival: A Post Hoc Time-Dependent Analysis of the Phase 3 Simplify-1, Simplify-2, and Momentum Trials

Introduction: The management of anemia in myelofibrosis (MF), a chronic progressive myeloproliferative neoplasm, remains an ongoing medical need as it is present in approximately 30% of patients (pts) at diagnosis and >50% after 1 year, contributing to negative impacts such as fatigue, medical complications, and poor quality of life. Furthermore, anemia and resulting transfusion need are independent predictors of poor prognosis. Momelotinib (MMB) is a Janus kinase (JAK) 1/JAK2/activin A receptor type 1 (ACVR1) inhibitor that has demonstrated spleen, symptom, and anemia benefits, including increases in hemoglobin (Hb) and reduction or elimination of red blood cell (RBC) transfusion requirements in pts with MF. Data from the phase 3 SIMPLIFY-1 (S1), SIMPLIFY-2 (S2), and MOMENTUM studies have shown an association between transfusion independence at wk 24 and prolonged overall survival (OS) with MMB (Mesa R, et al. Leukemia. 2022; Verstovsek S, et al. ASH 2022. Poster 3028). Because these analyses did not adjust for additional prognostic factors or effect modifiers nor potential longitudinal changes in transfusion status over time, the impact of transfusion status on OS has not been fully characterized. Here, we describe an analysis investigating the prognostic influence of RBC transfusion status over time and other covariates on OS from the S1 (NCT01969838), S2 (NCT02101268), and MOMENTUM (NCT04173494) studies irrespective of the treatment received. Methods: These treatment-agnostic OS analyses incorporated data from 3 multicenter, international, randomized trials investigating MMB vs an active comparator. Analyses were performed in the safety populations of S1 (N=430; MMB vs ruxolitinib [RUX], JAK inhibitor [JAKi] naive), S2 (N=156; MMB vs best available therapy [88.5% RUX], JAKi experienced), and MOMENTUM (N=195; MMB vs danazol, JAKi experienced). In the current analysis, which accounts for evaluations of transfusion status every 4 wk, time-dependent covariates (RBC transfusion status, categorized as either transfusion independent [TI; absence of RBC transfusion and no Hb level <8 g/dL in the prior 12 wk] or non-TI [not satisfying the criteria for TI]) and fixed baseline covariates (age, sex, MF subtype, Eastern Cooperative Oncology Group [ECOG] status, JAK2 mutational profile, Total Symptom Score, International Prognostic Scoring System [IPSS] score for S1, Dynamic IPSS [DIPSS] score for S2 and MOMENTUM, platelet count, baseline spleen volume as assessed by central reading of magnetic resonance imaging/computed tomography scan) were evaluated to determine their prognostic impact. An extended Cox model was used to generate an overall hazard ratio (HR) using all available follow-up time for each study, and independent variables were retained if a backward variable selection method determined that they were significantly associated with OS. Results: Significant covariates associated with survival across the 3 trials are presented in the table, with RBC transfusion status as a consistent prognostic variable. In S1, age, platelet count, and baseline spleen volume were also significantly associated with OS, and in S2, significant covariates included age, baseline spleen volume, and DIPSS. In MOMENTUM, only RBC transfusion status was significantly associated with survival. When accounting for differences in prognostic factors and effect modifiers as well as changes in transfusion status over time, results from MOMENTUM demonstrate a strong and significant relationship between transfusion status and OS (HR, 5.18; 95% CI, 1.86-14.47; P=.0017), suggesting that non-TI pts have a higher risk of all-cause mortality of more than 5 times that of TI pts. Similar results with respect to the survival benefits of TI status were observed in both S1 (HR, 3.32; 95% CI, 2.31-4.78; P<.0001) and S2 (HR, 1.87; 95% CI, 1.07-3.29; P=.0287). Conclusions: These data demonstrate that when accounting for differences in known prognostic factors and effect modifiers as well as changes in RBC transfusion status over time, a consistent and statistically significant relationship was observed between transfusion status and OS across all 3 phase 3 MMB trials. Consistent with inclusion of transfusion status in DIPSS-plus risk assessment, these data validate TI status as a clinically relevant and meaningful endpoint that is prognostic for survival in JAKi-naive and JAKi-experienced disease settings.

The contribution of prognostic factors to socio-demographic inequalities in breast cancer survival in Victoria, Australia.

Breast cancer survival in Australia varies according to socio-economic status (SES) and between rural and urban places of residence. Part of this disparity may be due to differences in prognostic factors at the time of diagnosis. Women with invasive breast cancer diagnosed from 2008 until 2012 (n = 14,165) were identified from the Victorian Cancer Registry and followed up for 5 years, with death from breast cancer or other causes recorded. A prognostic score, based on stage at diagnosis, cancer grade, whether the cancer was detected via screening, reported comorbidities and age at diagnosis, was constructed for use in a mediation analysis. Five-year breast cancer mortality for women with breast cancer who were in the lowest quintile of SES (10.3%) was almost double that of those in the highest quintile (5.7%). There was a small survival advantage (1.7% on average, within each socio-economic quintile) of living in inner-regional areas compared with major cities. About half of the socio-economic disparity was mediated by prognostic factors, particularly stage at diagnosis and the presence of comorbidities. The inner-regional survival advantage was not due to differences in prognostic factors. Part of the socio-economic disparity in breast cancer survival could be addressed by earlier detection in, and improved general health for, more disadvantaged women. Further research is required to identify additional causes of socio-economic disparities as well as the observed inner-regional survival advantage.

Comparing Prognostic Factors of Cancers Identified by Artificial Intelligence (AI) and Human Readers in Breast Cancer Screening.

Invasiveness status, histological grade, lymph node stage, and tumour size are important prognostic factors for breast cancer survival. This evaluation aims to compare these features for cancers detected by AI and human readers using digital mammography. Women diagnosed with breast cancer between 2009 and 2019 from three UK double-reading sites were included in this retrospective cohort evaluation. Differences in prognostic features of cancers detected by AI and the first human reader (R1) were assessed using chi-square tests, with significance at p < 0.05. From 1718 screen-detected cancers (SDCs) and 293 interval cancers (ICs), AI flagged 85.9% and 31.7%, respectively. R1 detected 90.8% of SDCs and 7.2% of ICs. Of the screen-detected cancers detected by the AI, 82.5% had an invasive component, compared to 81.1% for R1 (p-0.374). For the ICs, this was 91.5% and 93.8% for AI and R1, respectively (p = 0.829). For the invasive tumours, no differences were found for histological grade, tumour size, or lymph node stage. The AI detected more ICs. In summary, no differences in prognostic factors were found comparing SDC and ICs identified by AI or human readers. These findings support a potential role for AI in the double-reading workflow.

Differences in Prognostic Factors among Patients Hospitalized for Heart Failure According to the Age Category: From the KUNIUMI Registry Acute Cohort.

Objective Previous studies have described several prognostic factors for heart failure (HF); however, these results were derived from registries consisting of conventional age groups, which might not represent the increasingly aging society. The present study explored the prognostic factors for all-cause death in hospitalized patients with HF across different age categories using an acute HF registry that included relatively old patients. Methods From a total of 1,971 consecutive patients with HF, 1,136 patients were enrolled. We divided the patients into 4 groups (≤65, 66-75, 76-85, and >85 years old) to evaluate all-cause death and prognostic factors of all-cause death. Results During the mean follow-up period of 1,038 days, 445 patients (39.2%) had all-cause death. A Kaplan-Meier analysis demonstrated significantly higher incidence of all-cause death in the elderly groups than in the younger groups (log-rank p<0.001). A Cox proportional-hazard regression analysis revealed that the presence of atrial fibrillation [hazard ratio (HR): 23.3, 95% confidence interval (CI): 2.36-231.1, p=0.007] was a notable predictive factor for all-cause death in the ≤65 years old group, whereas the Clinical Frailty Scale score (HR: 1.33, 95% CI: 1.16-1.52, p<0.001) and hypoalbuminemia (HR: 0.49, 95% CI: 0.31-0.78, p=0.003) were predictors in the >85 years old group. Conclusions Atrial fibrillation was a notable predictor of HF in young patients, whereas frailty and low-grade albuminemia were essential predictive factors of HF in elderly patients. With the increasing number of elderly patients with HF, comprehensive multidisciplinary treatment will be necessary.

Outcomes of chronic subdural hematoma and their correlations with old age

Objective: This study explored the prognostic factors of chronic subdural hematoma in patients who underwent burr hole drainage, both overall and in elderly patients.Methods: This study enrolled 120 patients with chronic subdural hematoma who underwent burr hole drainage at a single center between January 2016 and December 2020. Old age was defined as &gt;65 years, and a good prognosis was defined as a decrease in the modified Rankin scale from admission to the last follow-up. Factors correlated with good prognosis in elderly patients compared with total patients were evaluated using the chi-square test and logistic regression analysis.Results: Among the 120 patients, 66 (55.0%) were ≥65 years old, and 76 (63.3%) had severe symptoms on admission. Old age (≥65) was the only factor significantly correlated with severe symptoms (P=0.021; odds ratio [OR], 2.618; 95% confidence interval [CI], 1.154–5.942). The following variables were significantly associated with the prognosis in both groups: diabetes (total: P=0.008; OR, 0.207; 95% CI, 0.064–0.664; old age: P=0.011; OR, 0.017; 95% CI, 0.044–0.672) and severe symptoms on admission (total: P&lt;0.001; OR, 6.994; 95% CI, 2.771–17.399; old age: P=0.007; OR, 6.177; 95% CI, 1.656–23.046).Conclusion: No difference in prognostic factors was observed between the overall patients and elderly patients with chronic subdural hematoma who underwent burr hole drainage. In both groups, patients without diabetes or with severe symptoms during hospitalization showed better recovery after burr hole drainage.

Distinct Prognostic Factors of Ground Glass Opacity and Pure-Solid Lesion in Pathological Stage I Invasive Lung Adenocarcinoma.

Ground glass opacity (GGO) is associated with favorable survival in lung cancer. However, the relevant evidence of the difference in prognostic factors between GGO and pure-solid nodules for pathological stage I invasive adenocarcinoma (IAC) is limited. We aimed to identify the impact of GGO on survival and find prognostic factor for part-GGO and pure-solid patients. Between December 2007 and August 2018, patients with pathological stage I IAC were retrospectively reviewed and categorized into the pure-GGO, part-GGO, and pure-solid groups. Survival curves were analyzed by the Kaplan-Meier method and compared by log-rank tests. Least absolute shrinkage and selection operator and Cox regression models were used to obtained prognostic factors for disease-free survival (DFS) and overall survival (OS). The number of patients with pure-GGO, part-GGO, and pure-solid was 134, 540, and 396, respectively. Part-GGO patients with consolidation-tumor-ratio (CTR) > 0.75 had similar outcome to those with pure-solid nodules. In part-GGO patients, CTR was negatively associated with OS (P = 0.007) and solid tumor size (STS) was negatively associated with DFS (P < 0.001). Visceral pleural invasion (VPI) was negatively associated with OS (P = 0.040) and DFS (P = 0.002). Sublobectomy was negatively associated with OS (P = 0.008) and DFS (P = 0.005), while extended N1 stations examination was associated with improved DFS (P = 0.005) in pure-solid patients. Though GGO component is a positively prognostic factors of patients with pathological stage I IAC, a small proportion of GGO components is not associated with favorable survival. VPI, STS and CTR are the significant predictors for part-GGO patients. Sublobectomy, especially wedge resection should be used cautiously in pure-solid patients.

Inflammatory bowel disease does not alter the clinical features and the management of acute pancreatitis: A prospective, multicentre, exact-matched cohort analysis

Objective and aimsAcute pancreatitis in inflammatory bowel disease occurs mainly as an extraintestinal manifestation or a side effect of medications. We aimed to investigate the prognostic factors and severity indicators of acute pancreatitis and the treatment of patients with both diseases. DesignWe performed a matched case-control registry analysis of a multicentre, prospective, international acute pancreatitis registry. Patients with both diseases were matched to patients with acute pancreatitis only in a 1:3 ratio by age and gender. Subgroup analyses were also carried out based on disease type, activity, and treatment of inflammatory bowel disease. ResultsNo difference in prognostic factors (laboratory parameters, bedside index of severity in acute pancreatitis, imaging results) and outcomes of acute pancreatitis (length of hospitalization, severity, and local or systemic complications) were detected between groups. Significantly lower analgesic use was observed in the inflammatory bowel disease population. Antibiotic use during acute pancreatitis was significantly more common in the immunosuppressed group than in the non-immunosuppressed group (p = 0.017). However, none of the prognostic parameters or the severity indicators showed a significant difference between any subgroup of patients with inflammatory bowel disease. ConclusionNo significant differences in the prognosis and severity of acute pancreatitis could be detected between patients with both diseases and with pancreatitis only. The need for different acute pancreatitis management is not justified in the coexistence of inflammatory bowel disease, and antibiotic overuse should be avoided.

Tumor Growth Inhibition-Overall Survival (TGI-OS) Model for Subgroup Analysis Based on Post-Randomization Factors: Application for Anti-drug Antibody (ADA) Subgroup Analysis of Atezolizumab in the IMpower150 Study.

Longitudinal changes of tumor size or tumor-associated biomarkers have been receiving growing attention as early markers of treatment benefits. Tumor growth inhibition-overall survival (TGI-OS) models represent mathematical frameworks used to establish a link from tumor size trajectory to survival outcome with the aim of predicting survival benefit with tumor data from a small number of subjects with a short follow-up time. In the present study, we applied the TGI-OS model to assess treatment benefit in the IMpower150 study for patients who exhibited development of anti-drug antibodies (ADA). Direct comparison between subgroups of the active arm [ADA positive (ADA +) and negative (ADA -) groups] to the entire control group is not appropriate, due to potential imbalances of baseline prognostic factors between ADA + and ADA - patients. Thus, the TGI-OS modeling framework was employed to adjust for differences in prognostic factors between the ADA subgroups to more accurately estimate the treatment benefits. After adjustment, the TGI-OS model predicted comparable hazard ratios (HRs) of OS between ADA + and ADA - subgroups, suggesting that the development of ADA does not have a clinically significant impact on the treatment benefit of atezolizumab.

Comparison of prognostic factors of esophageal cancer between a Chinese cohort and the Surveillance, Epidemiology, and End Results (SEER) database: a retrospective cohort study.

Esophageal cancer is a highly aggressive, early metastasis gastrointestinal malignancy, with geographic differences in prognosis. It is unknown whether there are differences in the survival in different regions among esophageal cancer patients who underwent the treatments. This study was to explore the influencing factors of esophageal cancer survival in patients from China and the Surveillance, Epidemiology, and End Results (SEER) database. The retrospective cohort study were conducted with 605 Chinese esophageal cancer patients in the Wuxi People's Hospital and 2,351 patients from the SEER database. The demographic and clinical data were collected from the two cohort, respectively. The outcome was the death during the follow-up. The follow-up ended on November 30, 2021. The Cox proportional hazards model was used in the univariate and multivariate survival analyses, with hazard ratio (HR) and 95% confidence interval (CI). In group one, the following were identified as the prognostic factors: female gender (HR =0.568; 95% CI: 0.398-0.811), T3 and T4 stages (HR =3.312; 95% CI: 2.493-4.401), N2 and N3 stages (HR =3.562; 95% CI: 2.631-4.824), and other subtypes of cancer (HR =0.393; 95% CI: 0.223-0.693). The following prognostic were factors identified in group two: age ≥65 years (HR =1.16; 95% CI: 1.058-1.276), female gender (HR =0.843; 95% CI: 0.752-0.945), T3 and T4 stages (HR =1.523; 95% CI: 1.373-1.690), M1 stage (HR =2.554; 95% CI: 2.303-2.832), treatment with surgery and chemotherapy (HR =0.507; 95% CI: 0.457-0.562), and other subtypes of cancer (HR =1.432; 95% CI: 1.298-1.581). There may be some differences in prognostic factors between Chinese and American patients with esophageal cancer. It is indicated that different management strategies of esophageal cancer should be considered in different populations to improve the prognosis of patients.

Long-term survival outcomes following resection of lung metastases (LM) from a colorectal primary.

50 Background: Liver metastatectomy in oligometastatic colorectal cancer (CRC) can result in long-term disease control1. The benefit of resecting LM is unclear, with good survival outcomes from medical therapy (MT) alone and a recent randomised controlled trial failed to demonstrate an overall survival (OS) benefit2. Methods: We examined TRACC (Treatment of Recurrent and Advanced Colorectal Cancer), a multisite registry for metastatic colorectal cancer (mCRC) patients (pts) from September 2002 – July 2021, focusing on the longer-term outcomes for pts with lung only metastatic disease (LOM). Key clinicopathological, treatment and outcome variables were analysed. Survival outcomes were determined by Kaplan-Meier method. Results: Of 3928 pts, 341 (8.7%) had LOM. The median OS was significantly improved for LOM vs. all mCRC pts (44.5 months vs. 24.8 months, p = &lt;0.0001). Of 341 LOM pts, 142 (42%) had lung resection (LRes),128 (38%) had MT, 71 (20%) best supportive care. Key clinicopathological characteristics are summarised in Table. OS was significantly longer for LRes vs. MT (3yrs-80.1% vs. 41.9%, p = &lt;0.0001, 5 yrs-65.2% vs. 21.1%, p = 0.0001). 10 yr survival for LRes was 50%, with no survivors from MT. The median palliative chemotherapy free interval was 13 months (95% CI 3.1 – 18.7) with recurrence after LRes/death. 20/142 (14%) of the LRes pts had recurrent LRes (median time to repeat resection of 11.4 months, median survival of 66.9 months from repeat LRes). Conclusions: LM from mCRC have an indolent course, with good survival outcomes with MT alone. LRes provides a clinically meaningful palliative chemotherapy free interval and long term survival in selected pts. Significant differences in prognostic factors may have contributed to the observed survival differences between LRes and MT.

The Extent of Honeycombing on Computed Tomography Cannot Predict the Treatment Outcome of Patients with Acute Exacerbations of Interstitial Lung Disease.

Background The purpose of this retrospective study was to clarify whether the presence of honeycombing on computed tomography (CT) can affect the prognosis of patients with acute exacerbations (AEs) of interstitial lung diseases (ILDs). Methods Clinical parameters including age, sex, Charlson Comorbidity Index Score (CCIS), blood biomarkers, and 3-month mortality were retrospectively compared between the CT honeycombing present and absent groups at the diagnosis of AEs of ILDs. Results Ninety-five patients who were on corticosteroid pulse therapy were assessed. Though log-rank tests showed that Kaplan–Meier survival curves of the high and low ground-glass opacity (GGO) score groups differed significantly in 3-month mortality in patients with AEs of idiopathic ILDs (P = 0.007) and overall patients (P = 0.045), there was no significant difference between the CT honeycombing present and absent groups in patients with AEs of idiopathic ILDs (P = 0.472) and AEs of secondary ILDs (P = 0.905), as well as of overall patients (P = 0.600). In addition, whereas CCIS (OR, 1.436; 95% CI, 1.156–1.842; P < 0.001) was a significant predictor of 3-month mortality in the CT honeycombing absent group, serum LDH (OR, 1.005; 95% CI, 1.002–1.007; P = 0.001) was a significant predictor in the CT honeycombing present group. Conclusions The clinical features of patients with or without honeycombing may differ due to the difference in prognostic factors, but these groups were found to have similar prognoses 3 months after AE onset, and clinicopathological examinations according to these groups are essential.

Unresected small lymph node assessment predicts prognosis for patients with pT3N0M0 thoracic esophageal squamous cell carcinoma

BackgroundThe role of unresected small lymph nodes (LNs) which may contain metastases for thoracic esophageal squamous cell carcinoma (TESCC) has not been addressed. The aim of the study was to investigate the role of unresected small LNs assessment using computed tomography (CT) in prognostic estimates of pT3N0M0 TESCC patients.MethodsBetween January 2009 and December 2017, 294 patients who underwent esophagectomy with R0 resection at Sichuan Cancer Hospital were retrospectively examined, and the last follow-up time was July 2018. Patients were classified into CT-suspect and CT-negative groups according to the shortest diameter and the shape (axial ratio) of the unresected small LNs on preoperative CT. The Kaplan–Meier method was used to compare survival differences in prognostic factors. Univariate and multivariate analyses were performed to identify prognostic factors for survival and recurrence.ResultsEighty-four patients (28.6%) were classified as CT-suspect group according to the diagnostic criteria; survival analysis suggested that CT-suspect group of patients had a relatively poorer prognosis (P<0.05). Cox regression analysis indicated that unresected small LNs status, tumor grade, and postoperative adjuvant therapy were independent prognostic factors for patients with pT3N0M0 TESCC (P<0.05). Further analysis shown the rates of total recurrence (TR) and locoregional recurrence (LR) in the CT-suspect group were significantly higher than that in the CT-negative group (TR, P<0.001; LR, P<0.001). Among the LRs, the rate of supraclavicular lymph node recurrence in the CT-suspect group was significantly higher than that in the CT-negative group (P<0.001).ConclusionsUnresected small lymph node assessment is critically important and predict prognosis for pT3N0M0 TESCC patients.

A 2-Year Prospective Study on the Differences in Prognostic Factors for Major Adverse Cardiovascular, Cerebrovascular and Renal Events Between Patients with Mild and Severe Chronic Kidney Disease.

Purpose/Method: No studies have reported on prognostic markers in patients with chronic kidney disease (CKD) according to the severity of the disease. Therefore, in this multicenter, prospective trial performed as part of the Gunma CKD SPECT Multicenter Study, we recruited 311 patients with CKD (eGFR < 60 min/mL/1.73 m2) including 50 patients on hemodialysis and followed them for 2 years. The study sample underwent stress 99mTc-tetrofosmin SPECT for suspected or possible ischemic heart disease. We evaluated the summed stress score (SSS), summed rest score (SRS), summed difference score (SDS) and cardiac function with electrocardiogram-gated SPECT. Then, we compared the differences in prognostic markers for major adverse cardiac, cerebrovascular, and renal events (MACCRE) between patients with mild CKD (30 min/mL/1.73 m2 ≤ eGFR <60 min/mL/1.73 m2; n=184) and those with severe CKD (eGFR <30 min/mL/1.73 m2; n=97). Results: Of 281 patients available for analysis, 91 experienced MACCRE. In a multivariate Cox proportional hazards analysis of factors related to MACCRE, in patients with mild CKD the significant prognostic markers were SDS (P=0.002) and end-systolic volume (ESV, P=0.034); and in the patients with severe CKD, they were eGFR (P=0.03) and diabetes-mellitus (DM, P=0.023). Conclusions: Our findings indicate that SDS and ESV are significant prognostic markers for MACCRE in patients with mild CKD and eGFR and DM are significant prognostic markers in patients with severe CKD.

Caucasians with acral lentiginous melanoma have the same outcome as patients with stage- and limb-matched superficial spreading melanoma

PurposeAcral lentiginous melanoma (ALM), a relatively rare subtype of cutaneous melanoma, has been reported to have a worse prognosis than other melanomas. We aimed to assess clinical findings in Caucasian ALM patients and compare the data with a matched cohort of superficial spreading melanoma (SSM) patients.MethodsWe studied 63 patients with ALM and 63 randomly stage- and limb-matched patients with SSM (non-ALM). In both cohorts, guideline-adjusted diagnosis, treatment and follow-up were performed.ResultsWe did not observe differences in prognostic factors (e.g., tumor thickness, ulceration) between the two cohorts. Both in ALM and non-ALM patients positive sentinel lymph node was a significant independent predictor for disease relapse and melanoma-specific death. However, disease relapse and melanoma-specific death rates did not significantly differ between ALM and non-ALM patients. An overall 5-year melanoma-specific survival of 82.5% and 81% was observed in ALM and non-ALM patients, respectively.ConclusionsOur data confirm that patients with ALM have no worse outcome than non-ALM patients when correcting for significant prognostic factors. Hence, the reportedly high rates of fatal ALM cases should not be ascribed to pathobiological differences between ALM and non-ALM but are most likely are a consequence of a delay in diagnosis and thus advanced stage of ALM.

Comparison of clinical characteristics and survival outcomes in patients with malignant peritoneal and pleural mesothelioma.

460 Background: Malignant peritoneal mesothelioma (MPeM) is an aggressive tumor strongly associated with asbestos exposure. We analyzed a large nationwide database to better understand the differences in the demographic and clinical patterns of MPeM and pleural mesothelioma (MPlM). Methods: The National Cancer Database (NCDB) 2010-15 was queried to identify all patients diagnosed with MpeM and MPlM. The demographic and clinical characteristics were compared using Pearson’s chi-square test. Kaplan-Meier method and associated log-rank test were used to compare the unadjusted overall survival of the two malignant mesothelioma (MM) sites. A multivariate Cox regression analysis was done to determine survival difference between the 2 groups. Results: Of the 8,668 patients included in the study, 1,081 (12.5%) had MPeM and 7,587 (87.5%) had MPlM. The MPeM cohort was younger (median age at diagnosis 61 vs 73 years), predominantly females (45.7% vs 23.5%), had a lower Charlson Deyo Comorbidity Score ( &gt; = 1: 24.5% vs 32.1%), had higher percentage of uninsured patients (4% vs 2.2%), was less likely to be treated at a community or comprehensive community center (36.1% vs 47.3%) and had lower proportion of sarcomatous or biphasic histology (9.3% vs 22.4%) compared to MPlM cohort. The MPeM cohort was more likely to receive surgery (56.5% vs 28%) and chemotherapy (68.4% vs 54.5%) but less likely to receive radiation (0.8% vs 11%). The p-value was &lt; 0.001 for all comparisons. The median OS was 19.7 and 9.7 months for patients with MPeM and MPlM, respectively (log-rank p value &lt; 0.001). On multivariate Cox proportional hazards analysis, OS was significantly worse for MPlP compared to MPeP [HR adj: 1.19, 95% confidence interval (CI): 1.09-1.30 (p &lt; 0.001)]. Conclusions: There is paucity of data about clinical characteristics and outcomes of MPeM. Much of our current knowledge about MPeM is extrapolated from MPlM. Our study suggests significant differences in prognostic factors and survival outcomes between the two sites.

CML-246: Systematic Literature Review of the Efficacy of Available Interventions for Patients with Chronic-Phase (CP) Chronic Myeloid Leukemia (CML) Who Have Previously Been Treated with ≥2 Lines of Tyrosine Kinase Inhibitors (TKIs)

Context and Objective Despite several TKIs being available as standard of care for CP-CML patients, survival rates are low once patients move beyond their second line of treatment. This study aimed to systematically capture and summarize evidence on treatment outcomes for CP-CML patients previously treated with ≥2 lines of TKIs. Methods The search was conducted in November 2019 within Embase, MEDLINE, and Cochrane, to identify studies of TKIs, allogeneic stem cell transplantation (allo-SCT), omacetaxine, and hydroxycarbamide in the target population. Outcomes of interest were complete cytogenetic response (CCyR), major molecular response (MMR), as well as 4-log (MR4), 4.5-log (MR4.5), and 5-log (MR5) reductions in BCR-ABL ratio, and survival (progression-free [PFS] and overall [OS]). Results Seven single-arm trials and 12 observational studies were included, with no randomized controlled trial (RCT) of relevance being identified. Six studies featured multiple interventions, all of which were observational. Seven studies evaluated dasatinib, seven nilotinib, six bosutinib, five ponatinib, one omacetaxine, one imatinib, and one allo-SCT. Sample sizes ranged between 10 and 270 patients. Median age and proportion of males ranged from 33 to 68 years and from 45% to 65%, respectively. Among the seven studies reporting on performance status, patients had an ECOG score of either 0 or 1. Between 0% and 54% of patients were in CCyR at study entry. Median PFS and median OS were not reached with ponatinib, bosutinib, dasatinib, or nilotinib, were not reported with allo-SCT, and were 9.6 and 33.9 months with omacetaxine. CCyR, MMR, MR4, and MR4.5 rates (reported in 18, 18, five, and five studies respectively) ranged from 5% to 81%, 8% to 72%, 20% to 57%, and 16% to 57%. No study reported MR5. Conclusions No RCT has been conducted in this population. Since most included studies were observational, with known associated risks of bias, there is a clear need for data generation through RCTs. Long-term outcomes were generally poor; differences in prognostic factors at baseline may explain part of the heterogeneity in the reported outcomes. Comparative evidence on the efficacy of interventions is needed to aid clinicians in managing this heavily pretreated population.

Meniscus or Cartilage Injury at the Time of Anterior Cruciate Ligament Tear Is Associated With Worse Prognosis for Patient-Reported Outcome 2 to 10 Years After Anterior Cruciate Ligament Injury: A Systematic Review.

(1) To assess prognostic factors for patient-reported outcome measures (PROMs) and physical activity 2 to 10 years after anterior cruciate ligament reconstruction (ACLR) or anterior cruciate ligament (ACL) injury, and (2) to assess differences in prognostic factors between patients treated with ACLR and with rehabilitation alone. Prognosis systematic review. Systematic searches were performed in PubMed, Web of Science, and SPORTDiscus. We selected prospective cohort studies and randomized clinical trials that included adults or adolescents undergoing either ACLR or rehabilitation alone after ACL rupture. Studies had to assess the statistical association between potential prognostic factors (factors related to patient characteristics, injury, or knee symptoms/function measured at baseline or within 1 year) and outcomes (PROMs and physical activity). Our search yielded 997 references. Twenty studies met the inclusion criteria. Seven studies with low or moderate risk of bias remained for data synthesis. Moderate-certainty evidence indicated that concomitant meniscus and cartilage injuries were prognostic factors for worse PROMs 2 to 10 years after ACLR. Very low-certainty evidence suggested that body mass index, smoking, and baseline PROMs were prognostic factors for worse outcome. Very low-certainty evidence suggested that female sex and a worse baseline Marx Activity Rating Scale score were prognostic factors for a worse Marx Activity Rating Scale score 2 to 10 years after ACLR. There was a lack of studies on prognostic factors after rehabilitation alone. Concomitant meniscus and cartilage injuries were prognostic factors for worse long-term PROMs after ACLR. The certainty was very low for other prognostic factors. J Orthop Sports Phys Ther 2020;50(9):490-502. Epub 1 Aug 2020. doi:10.2519/jospt.2020.9451.
