Predictors of Local Control With Palliative Radiotherapy for Multiple Myeloma.

Introduction: We performed a retrospective analysis of patients with multiple myeloma (MM) receiving palliative radiotherapy (RT) and assessed factors associated with local control, with a focus on dose/fractionation and cytogenetics.

Materials And Methods: We included patients who received palliative RT for MM at our institution. Cytogenetics were collected via fluorescence in situ hybridization.

Incident cardiovascular disease risk among older Asian, Native Hawaiian and Pacific Islander liver cancer survivors.

Background: Cardiovascular disease (CVD) is a significant global health concern, particularly among Asian, Native Hawaiian, and Pacific Islander (ANHPI) communities that face unique health challenges. Liver cancer disproportionately affects ANHPI populations and has intricate associations with CVD risks due to shared pathophysiological mechanisms and metabolic disturbances. However, the specific CVD risk profile of ANHPI liver cancer patients remains poorly understood.

Incident diabetes among older Asian, Native Hawaiian, and Pacific Islander women with breast cancer.

Background: The risk of diabetes among Asian, Native Hawaiian, and Pacific Islander (ANHPI) women after breast cancer is unclear. This study estimated the risk of incident type II diabetes in older ANHPI and older non-Hispanic White (NHW) women with breast cancer from the US National Cancer Institute's Surveillance, Epidemiology, and End Results (SEER) Medicare linked claims.

Methods: A matched cohort of 7122 older ANHPI and 21 365 older NHW women with breast cancer were identified from SEER-Medicare between 2000 and 2017.

Survival Outcomes of Limited-Stage Diffuse Large B-Cell Lymphoma Treated With Radiation Therapy.

Background: Patients with favorable risk limited-stage (LS) diffuse large b-cell lymphoma (DLBCL) have shown excellent outcomes without radiotherapy (RT). However, the role of RT for the remainder of LS-DLBCL patients is less well defined. We aimed to investigate whether the addition of RT provided an overall survival (OS) benefit in a real-world cohort of LS-DLBCL patients based on primary site at presentation.

A systematic review and meta-analysis of pathologic complete response rates for patients with cholangiocarcinoma treated on liver transplant protocols.

Unlabelled: BACKGROUND AND OBJECTIVES: Many heterogenous orthotopic liver transplant (OLT) protocols exist for patients with unresectable cholangiocarcinoma. Little is known about the incidence, predictors for, and the significance of achieving a pathologic complete response (pCR).

Methods: We performed a systematic review through September 2022 of the PubMed, Embase, and Web of Science databases.

Neoadjuvant Therapy Regimens for Hilar Cholangiocarcinoma Before Liver Transplant.

Objectives: Patients with unresectable hilar cholangiocarcinoma (hCCA) may be eligible for curative treatment through liver transplantation (LT). Neoadjuvant protocols often include radiotherapy (RT), however, there is no standard RT approach. The purpose of this study is to characterize practice patterns of RT use before transplantation for hCCA.

Secondary malignancies in non-Hodgkin lymphoma survivors: 40 years of follow-up assessed by treatment modality.

Background: Survivors of non-Hodgkin lymphoma (NHL) have increased secondary malignancy (SM) risk. We quantified this risk by patient and treatment factors.

Methods: Standardized incidence ratios (SIR, observed-to-expected [O/E] ratio) were assessed in 142,637 NHL patients diagnosed from 1975 to 2016 in the National Cancer Institute's Surveillance, Epidemiology, and End Results Program.

Second Primary Malignancies in Diffuse Large B-cell Lymphoma Survivors with 40 Years of Follow Up: Influence of Chemotherapy and Radiation Therapy.

Purpose: Previous studies have shown an increased risk of second primary malignancies (SPMs) in survivors of diffuse large B-cell lymphoma (DLBCL). Survivors live longer due to the intensification of and improvements in therapy; thus, we aimed to characterize SPM patterns in patients with DLBCL by treatment modality.

Methods And Materials: Standardized incidence ratio and absolute excess risk of SPMs were assessed in patients with primary DLBCL from 1975 to 2016 in the National Cancer Institute's Surveillance, Epidemiology, and End Results Program.

Evaluating patterns of care for early-stage low-grade follicular lymphoma in the rituximab era.

Radiotherapy (RT) utilization for early-stage, low-grade follicular lymphoma (FL) is low despite treatment guideline recommendations. We compare treatment trends for early-stage FL in the era of involved-site RT and rituximab. We identified 11,645 patients in the National Cancer Database (NCDB) with stage I-II, grade 1-2 nodal or extranodal FL diagnosed 2011-2017, with median follow-up of 44 months.

Mental health disorders are more common in patients with Hodgkin lymphoma and may negatively impact overall survival.

Background: Long-term mental health outcomes were characterized in patients who were diagnosed with Hodgkin lymphoma (HL), and risk factors for the development of mental health disorders were identified.

Methods: Patients who were diagnosed with HL between 1997 and 2014 were identified in the Utah Cancer Registry. Each patient was matched with up to five individuals from a general population cohort identified within the Utah Population Database, a unique source of linked records that includes patient and demographic data.

Patterns of care and outcomes of early stage I-II Hodgkin lymphoma treated with or without radiation therapy.

Omission of radiotherapy in the upfront management of early-stage classic Hodgkin lymphoma (cHL) has become more common with time. We report patterns of care and outcomes of stage I-II cHL treated with chemotherapy (CT) only versus CT and radiotherapy (combined modality therapy, CMT). From the National Cancer Database, we identified 28,327 early-stage cHL patients treated with CT ( = 15,798) or CMT ( = 12,529) from 2004 to 2018.

Feasibility and Clinical Utility of a Workflow Interfacing Radiation Oncology Lung Stereotactic Body Radiation Therapy Treatment Planning and Diagnostic Radiology.

Stereotactic body radiation therapy (SBRT) is commonly used to treat early-stage non-small cell lung cancer. Beam arrangements for SBRT include multiple entry and exit pathways resulting in irregular low-dose distributions within normal lung parenchyma. An improved understanding of posttreatment radiographic changes may improve the ability to predict clinical complications including radiation pneumonitis as well as assist in early detection of local failures.

Improved overall survival over time in advanced stage mycosis fungoides: a cross-sectional study.

Mycosis Fungoides (MF) is a rare T-cell lymphoma and evidence on treatment practices, and outcomes are limited. We evaluated changes in practice patterns and corresponding effects on overall survival (OS) in MF using a cross-sectional study of patients diagnosed with MF from 2004 to 2016 in the National Cancer Database. Outcomes evaluated included patterns of care and OS across treatment eras.

The Implications of Treatment Delays in Adjuvant Therapy for Resected Cholangiocarcinoma Patients.

Purpose: The purpose of this study is to understand factors associated with timing of adjuvant therapy for cholangiocarcinoma and the impact of delays on overall survival (OS).

Methods: Data from the National Cancer Database (NCDB) for patients with non-metastatic bile duct cancer from 2004 to 2015 were analyzed. Patients were included only if they underwent surgery and adjuvant chemotherapy and/or radiotherapy (RT).

Near Complete Response to Trametinib Treatment in Histiocytic Sarcoma Harboring a Somatic KRAS Mutation.

Survival outcomes of patients with histiocytic neoplasms are poor, with no standard-of-care treatments available for these malignancies. Recent characterization of the genomic landscape of various histiocytic neoplasms have shown a predominance of activating driver mutations within the MAPK/ERK pathway (ie, BRAF, MEK, KRAS, MAPK, and NRAS). Subsequently, successful treatment of these malignancies with BRAF and MEK inhibitors has been reported.

Screening and verification of potential gene targets in esophageal carcinoma by bioinformatics analysis and immunohistochemistry.

Background: To evaluate the potential of candidate proteins as diagnostic markers or drug targets in esophageal carcinoma (ESCA).

Methods: GSE20347, GSE17351, and GSE45670 were downloaded from Gene Expression Omnibus (GEO). Differently expressed genes (DEGs) between ESCA and normal esophageal tissues from patients were obtained.

Factors associated with the refusal of surgery and the associated impact on survival in patients with rectal cancer using the National Cancer Database.

Background: Surgical resection is an integral component of the curative-intent treatment for most patients with non-metastatic rectal cancer. However, some patients refuse surgery for a number of reasons. Utilizing the National Cancer Database (NCDB), we investigated the sociodemographic and clinical factors associated with patients who were coded as having been offered but refused surgery, and the factors affecting overall survival (OS) in these patients.

Radiation-Associated Lymphopenia and Outcomes of Patients with Unresectable Hepatocellular Carcinoma Treated with Radiotherapy.

Background: The immune system plays a crucial role in cancer surveillance. Previous studies have shown that lymphopenia associated with radiotherapy (RT) portends a poor prognosis. We sought to differentiate the effects of proton and photon RT on changes in absolute lymphocyte count (ALC) for patients with hepatocellular carcinoma (HCC).

Young Adult Populations Face Yet Another Barrier to Care With Insurers: Limited Access to Proton Therapy.

Purpose: Young patients, including pediatric, adolescent, and young adult (YA) patients, are most likely to benefit from the reduced integral dose of proton beam radiation therapy (PBT) resulting in fewer late toxicities and secondary malignancies. This study sought to examine insurance approval and appeal outcomes for PBT among YA patients compared with pediatric patients at a large-volume proton therapy center.

Methods And Materials: We performed a cross-sectional cohort study of 284 consecutive patients aged 0 to 39 years for whom PBT was recommended in 2018 through 2019.

The Effect of Measured Radiotherapy Dose on Intrathecal Drug Delivery System Function.

Objectives: Radiation therapy (RT) and intrathecal drug delivery systems (IDDS) are often used concurrently to optimize pain management in patients with cancer. Concern remains among clinicians regarding the potential for IDDS malfunction in the setting of RT. Here we assessed the frequency of IDDS malfunction in a large cohort of patients treated with RT.
