Waldenström macroglobulinemia (WM) is a B-cell lymphoma characterized by the presence of bone marrow lymphoplasmacytic infiltration and circulating monoclonal immunoglobulin M protein. The clinical presentation of WM is variable, ranging from gradually progressive cytopenias, organomegaly, fatigue, B symptoms, and peripheral neuropathy to the more emergent presentation with symptomatic hyperviscosity, cryoglobulinemia, hemolytic anemia-associated symptoms, acquired von Willebrand disease or acquired hemophilia-associated bleeding. Approximately 1 in 5 patients with WM are asymptomatic at diagnosis and classified as having smoldering WM, not requiring WM-directed therapy. Although WM typically has an indolent, relapsing-remitting course, the outcomes are heterogeneous. The prognosis of patients with WM is known to be impacted by certain clinical and laboratory features at initial presentation, with advanced age, elevated serum lactate dehydrogenase, and low serum albumin unfavorably affecting the outcome. Although complications such as histologic transformation or light and/or heavy chain (AL/ALH) amyloidosis are infrequent, their occurrence adversely influences the disease course. The International Prognostic Staging System for WM (IPSS-WM) is a validated model, often used in clinical practice, but needs to be reexamined in the current era. The discovery of the recurrent MYD88L265P gain-of-function point mutation and the subclonal CXCR4 mutations has helped improve our understanding of the WM biology, and the prognostic impact of these mutations is under evaluation, with somewhat inconsistent findings thus far across studies. This review discusses the clinical presentation, diagnostic criteria, and prognostic markers of WM.

Background: The Clinical Treatment Score post-5 years (CTS5) is a risk stratification tool used to determine the risk of late recurrence in hormone receptor-positive (HR+), HER2-negative breast cancer (BC). Limited data exist on its use in HR+, HER2-positive (HER2+) BC.

Patients and methods: CTS5 was evaluated in HR+, HER2+ BC in the North Central Cancer Treatment Group (NCCTG) N9831 (Alliance) and NSABP B-31 (NRG) trials.

Results: A total of 1,862 patients with HR+, HER2+ BC without recurrence 5 years after enrollment were included. Overall, the CTS5 score was significantly associated with recurrence-free survival (RFS), with a hazard ratio (HR) of 1.35 (95% CI, 1.12-1.63; P=.002), but did not reach statistical significance in patients who received trastuzumab (n=829; HR, 1.29; 95% CI, 0.98-1.71; P=.07). CTS5 risk category was not significantly associated with RFS. In patients who received trastuzumab, other variables used in CTS5, including patient age and tumor size, were not significantly associated with RFS. N3 was significantly associated with worse outcomes (HR, 1.86; 95% CI, 1.09-3.17; P=.02) compared with N0-N1. Paradoxically, higher tumor grade was associated with better outcomes after 5 years in the multivariate analysis (HR, 0.71; 95% CI, 0.50-1.00; P=.05). The incidence of recurrences or deaths between years 5 to 10 was 10.6% in the CTS5 low-risk category, 5.6% in the intermediate-risk category, and 9.8% in the high-risk category.

Conclusions: The CTS5 model does not accurately predict the risk of late recurrence in HR+, HER2+ BC treated with adjuvant trastuzumab in the N9831 and B-31 trials. This study underlines the need to develop a new prognostic model to better delineate the risk of late recurrence in patients with HR+, HER2+ BC receiving adjuvant trastuzumab.

Clinicaltrials: gov identifiers: NCT00005970 (NCCTG N9831) and NCT00004067 (NRG/NSABP B-31).

Background: Individuals with a history of cancer increasingly seek health information from online resources, including NCI-designated Cancer Center websites. Centers receive NCI designation because they provide excellent care and engage in cutting-edge research. However, the information presented on these webpages and their accessibility is unknown. An evaluation of the survivorship-focused webpages from NCI-designated Cancer Centers is needed to assess survivorship information and accessibility of these webpages.

Methods: We conducted an evaluation of the survivorship-focused webpages from 64 NCI-designated Cancer Centers. We evaluated where survivorship-focused webpages were housed, if there was a survivorship clinic or program, target audience of the webpage, how cancer survivor was defined, contact methods, and available resources. Accessibility outcomes included readability, font type, font size, color scheme, and alternative text (alt text) descriptors. An artificial intelligence (AI) audit was conducted to assess if the webpage was compliant with national accessibility guidelines.

Results: Most cancer centers had a survivorship-focused webpage, with 72% located on the cancer center's website and 28% on a health system website. Survivorship information available varied considerably and was often lacking in detail. Although three-quarters of webpages targeted patients only, variable definitions of cancer survivor were observed. Accessibility issues identified included inconsistent use of alt text descriptors, font size smaller than 15 points, and color schemes without adequate contrast. The average reading-level of information presented was above 12th grade. Only 9% of webpages were compliant with online accessibility guidelines; 72% semicompliant and 21% were noncompliant.

Conclusions: Information presented on NCI-designated Cancer Center survivorship-focused webpages was inconsistent, often lacking, and inaccessible. NCI-designated Cancer Centers are role models for cancer research in the United States and have an obligation to provide survivorship information. Changes to content and website design are needed to provide better information for individuals seeking resources and health information relative to their cancer and care.

Background: Some genomic alterations in non-small cell lung cancer (NSCLC) are known to differ according to race, sex, or age. These studies have been limited in sample size and thus they cannot detect the differences precisely and comprehensively.

Methods: Tissue-based comprehensive genomic profiling was performed on 75,362 patients with NSCLC from the United States during routine clinical care. Additionally, we examined data of a Japanese NSCLC cohort with 1,019 patients. In the US cohort, 296 genes were examined for pathogenic alterations. Predominant genetic ancestry was inferred using a SNP-based approach, and patients were categorized into European (EUR), African (AFR), East Asian (EAS), Admixed American (AMR), and South Asian (SAS) ancestry groups. Patients were additionally stratified by histologic type, age (<40/≥40 years, <75/≥75 years), and sex. The prevalence of high tumor mutational burden (TMB-High) and microsatellite instability status was also calculated.

Results: Stratified by ancestry, EGFR alterations were significantly enriched in EAS versus other ancestry groups. The prevalence of ALK was significantly higher in the AMR, EAS, and SAS patients than in AFR and EUR patients. KRAS and STK11 were enriched in EUR and AFR patients versus other groups. TMB-High was significantly enriched in AFR patients versus all other groups. An analysis based on sex revealed differences in prevalence of alterations in 80 genes and TMB-High status. For example, EGFR, ALK, BRAF, and KRAS alterations were significantly enriched in females, whereas TP53, STK11, KEAP1, and TMB-High were significantly enriched in males. With respect to age, the prevalence of alterations in 41 genes, including ALK, RET, MET, EGFR, STK11, KEAP1, BRAF, and KRAS, as well as TMB-High, were significantly different between patients aged <40 years and those aged ≥40 years.

Conclusions: Comprehensive analysis from a large real-world dataset revealed ancestry-associated differences in genomic alterations in NSCLC. Age- and sex-related differences in prevalence of genomic alterations and TMB-High status were also observed.

The determination of an optimal treatment plan for an individual patient with rectal cancer is a complex process. In addition to decisions relating to the intent of rectal cancer surgery (ie, curative or palliative), consideration must also be given to the likely functional results of treatment, including the probability of maintaining or restoring normal bowel function/anal continence and preserving genitourinary functions. Particularly for patients with distal rectal cancer, finding a balance between curative-intent therapy while having minimal impact on quality of life can be challenging. Furthermore, the risk of pelvic recurrence is higher in patients with rectal cancer compared with those with colon cancer, and locally recurrent rectal cancer is associated with a poor prognosis. Careful patient selection and the use of sequenced multimodality therapy following a multidisciplinary approach is recommended. These NCCN Guidelines Insights detail recent updates to the NCCN Guidelines for Rectal Cancer, including the addition of endoscopic submucosal dissection as an option for early-stage rectal cancer, updates to the total neoadjuvant therapy approach based on the results of recent clinical trials, and the addition of a "watch-and-wait" nonoperative management approach for clinical complete responders to neoadjuvant therapy.

Neuroblastoma is the most common extracranial solid tumor diagnosed in children. This inaugural version of the NCCN Guidelines for Neuroblastoma provides recommendations for the diagnosis, risk classification, and treatment of neuroblastoma. The information in these guidelines was developed by the NCCN Neuroblastoma Panel, a multidisciplinary group of representatives with expertise in neuroblastoma, consisting of pediatric oncologists, radiologists, pathologists, surgeons, and radiation oncologists from NCCN Member Institutions. The evidence-based and consensus recommendations contained in the NCCN Guidelines are intended to guide clinicians in selecting the most appropriate treatments for their patients with this clinically heterogeneous disease.

Background: Limited real-world evidence is available comparing the safety and effectiveness of apixaban and low-molecular-weight heparins (LMWHs) for preventing recurrent venous thromboembolism (VTE) in patients with active cancer receiving anticoagulation in an extended treatment setting. This study evaluated the risk of bleeding and recurrent VTE in patients with cancer-associated VTE who were prescribed apixaban or LMWH for ≥3 months.

Methods: A US commercial claims database was used to identify adult patients with VTE and active cancer who initiated apixaban or LMWH 30 days following the first VTE diagnosis and had ≥3 months of continuous enrollment and 3 months of primary anticoagulation treatment. Patients were followed from the day after the end of primary anticoagulation treatment until the earliest of: date of disenrollment, discontinuation of index anticoagulant, switch to another anticoagulant, or end of the study period. Inverse-probability treatment weighting (IPTW) was used to balance treatment cohorts. Incidence rates (IRs) for the outcomes were calculated per 100 person-years (PY). Cox proportional hazard models were used to evaluate the adjusted risk of recurrent VTE, major bleeding (MB), and clinically relevant nonmajor bleeding (CRNMB).

Results: A total of 13,564 apixaban- and 2,808 LMWH-treated patients were analyzed. Post-IPTW, the treatment cohorts were balanced. Patients receiving apixaban had lower adjusted IRs for recurrent VTE (4.1 vs 9.6 per 100 PY), MB (6.3 vs 12.6), and CRNMB (26.1 vs 36.0) versus LMWH (P<.0001 for all comparisons) during the follow-up period. Patients on apixaban had a lower adjusted risk of recurrent VTE (hazard ratio [HR], 0.42; 95% CI, 0.34-0.53), MB (HR, 0.50; 95% CI, 0.41-0.61), and CRNMB (HR, 0.76; 95% CI, 0.68-0.85) versus LMWH.

Conclusions: Extended anticoagulation treatment of ≥3 months with apixaban was associated with lower rates of recurrent VTE, MB, and CRNMB compared with LMWH in adults with cancer-associated VTE.
