A prospective cohort study on stereotactic radiotherapy in the management of dural recurrence of olfactory neuroblastoma.

Background: Treatment for dural recurrence of olfactory neuroblastoma (ONB) is not standardized. We assess the outcomes of stereotactic body radiotherapy (SBRT) in this population.

Methods: ONB patients with dural recurrences treated between 2013 and 2022 on a prospective registry were included.

Racial and Ethnic Differences in Long-Term Adverse Radiation Therapy Effects Among Breast Cancer Survivors.

Purpose: Breast and skin changes are underrecognized side effects of radiation therapy for breast cancer, which may have long-term implications for quality of life (QOL). Racial and ethnic disparities in breast cancer outcomes, including long-term QOL differences after breast radiation therapy, are poorly understood.

Methods And Materials: We conducted a cross-sectional survey study of patients from the Texas Cancer Registry who received diagnoses of stage 0-II breast cancer from 2009 to 2014 and treated with lumpectomy and radiation therapy; 2770 patients were sampled and 631 responded (23%).

Financial toxicity in cancer patients and subsequent risk of repeat acute care utilization.

Background: Acute care (AC) visits by cancer patients are costly sources of healthcare resources and can exert a financial burden of oncology care both for individuals with cancer and healthcare systems. We sought to identify whether cancer patients who reported more severe initial financial toxicity (FT) burdens shouldered excess risks for acute care utilization.

Methods: In 225 adult patients who participated in the Economic Strain and Resilience in Cancer (ENRICh) survey study of individuals receiving ambulatory cancer care between March and September 2019, we measured the baseline FT (a multidimensional score of 0-10 indicating the least to most severe global, material, and coping FT burdens).

Long-term Patient-Reported Outcomes in a Population-Based Cohort Following Radiotherapy vs Surgery for Oropharyngeal Cancer.

Importance: Oncologic outcomes are similar for patients with oropharyngeal squamous cell carcinoma (OPSCC) treated with primary surgery or radiotherapy. However, comparative differences in long-term patient-reported outcomes (PROs) between modalities are less well established.

Objective: To determine the association between primary surgery or radiotherapy and long-term PROs.

Patient-reported Quality of Life After Breast-conserving Surgery With Radiotherapy Versus Mastectomy and Reconstruction.

Objective: To compare long-term quality of life (QOL) outcomes in breast cancer survivors who received breast-conserving surgery with radiotherapy (BCS+RT) with those who received a mastectomy and reconstructive surgery (Mast+Recon) without radiotherapy and identify other important factors.

Background: The long-term differences in patient-reported QOL outcomes following BCS+RT and Mast+Recon are not well understood.

Methods: We identified patients from the Texas Cancer Registry with stage 0-II breast cancer diagnosed in 2009-2014 after BCS+RT or Mast+Recon without radiotherapy.

Patient-Reported Financial Toxicity in a Population-Based Cohort of Oropharynx Cancer Survivors.

Purpose: Patients with oropharyngeal squamous cell carcinoma (OPSCC) are at high risk for financial toxicity (FT), but the nature, extent, and predictors of FT experienced after primary radiation therapy (RT) or surgery are poorly understood.

Methods And Materials: We used a population-based sample of patients from the Texas Cancer Registry with stage I to III OPSCC diagnosed from 2006 to 2016 and treated with primary RT or surgery. Of 1,668 eligible patients, 1,600 were sampled, 400 responded, and 396 confirmed OPSCC.

Postoperative radiotherapy with modern techniques does not improve survival for operable stage IIIA-N2 non-small cell lung cancer.

Objectives: This study aims to evaluate whether postoperative radiotherapy using newer techniques (intensity-modulated radiotherapy [IMRT]) is associated with improved survival for patients with stage IIIA-N2 non-small cell lung cancer (NSCLC) who underwent complete resection.

Methods: The overall survival of patients with stage IIIA-N2 NSCLC who received postoperative IMRT versus no postoperative IMRT following induction chemotherapy and lobectomy in the National Cancer Database from 2010-2018 was assessed via Kaplan-Meier analysis, Cox proportional hazards analysis and propensity score-matched analysis. Additional survival analyses were also conducted in patients with completely resected stage IIIA-pN2 NSCLC who had upfront lobectomy (without induction therapy) followed by adjuvant chemotherapy alone or adjuvant chemotherapy with postoperative IMRT.

Association of fall rate and functional status by genotype in cancer survivors after exercise intervention.

Purpose/objectives: Cancer treatment survivors often report impaired functioning and increased falls. Not all survivors experience the same symptom burden, suggesting individual susceptibilities. genotype is a potential genetic risk factor for cancer treatment related side effects.

Long-term Oncologic Outcomes in Patients with Inflammatory Breast Cancer with Supraclavicular Nodal Involvement.

Background: Inflammatory breast cancer (IBC) is a rare and aggressive subtype of breast cancer characterized by rapid progression and early metastasis, often with advanced nodal locations, including the supraclavicular (SCV) nodal basin. Previously considered M1 disease, ipsilateral clinical supraclavicular node involvement (N3c) disease is now considered locally advanced disease and warrants treatment with intent to cure. The objective of this study was to evaluate the long-term outcomes of patients with IBC and N3c disease.

Perspectives of Zambian Clinical Oncology Trainees in the MD Anderson and Zambia Virtual Clinical Research Training Program (MOZART).

Background: African countries are underrepresented in cancer research, partly because of a lack of structured curricula on clinical research during medical education. To address this need, the MD Anderson and Zambia Virtual Clinical Research Training Program (MOZART) was developed jointly by MD Anderson Cancer Center (MDA) and the Cancer Diseases Hospital in Zambia (CDH) for Zambian clinical oncology trainees. We explored participant perspectives to provide insight for implementation of similar efforts.

Building Capacity for Cancer Research in the Era of COVID-19: Implementation and Results From an International Virtual Clinical Research Training Program in Zambia.

Purpose: The incidence of cancer in sub-Saharan Africa is increasing rapidly, yet cancer research in the region continues to lag. One contributing factor is limited exposure to clinical research among trainees. We describe implementation and results of a virtual clinical research training program for Zambian clinical oncology fellows developed jointly by the Cancer Diseases Hospital in Zambia and the MD Anderson Cancer Center to address this need.

Locoregional Management and Prognostic Factors in Breast Cancer With Ipsilateral Internal Mammary and Axillary Lymph Node Involvement.

Purpose: Patients with breast cancer and ipsilateral axillary and internal mammary (IM) lymph node involvement (cN3b) often forgo IM node resection. Therefore, radiation is important for curative therapy. However, prognosis is not well described in the era of modern systemic therapy, and limited data exist to guide optimal locoregional treatment recommendations.

Contemporary Outcomes After Multimodality Therapy in Patients With Breast Cancer Presenting With Ipsilateral Supraclavicular Node Involvement.

Purpose: Patients with breast cancer and ipsilateral supraclavicular (SCV) node involvement at the time of diagnosis (TNM cN3c) have historically had poor outcomes. Radiation therapy (RT) has an important role because SCV nodes are not routinely surgically dissected. However, optimal locoregional management, contemporary outcomes, and prognostic factors are not well defined.

Management of complications from brain metastasis treatment: a narrative review.

Objective: To describe the range of potential side effects associated with modern brain metastasis treatment and provide evidenced-based guidance on the effective management of these side effects.

Background: Brain metastases are the most commonly diagnosed malignant intracranial tumor and have historically been associated with very poor prognosis. The standard treatment for brain metastases until the 1990s was whole-brain radiation therapy (WBRT) alone.

Stereotactic body ablative radiotherapy for reirradiation of small volume head and neck cancers is associated with prolonged survival: Large, single-institution, modern cohort study.

Background: Recurrent head and neck cancer has poor prognosis. Stereotactic body radiotherapy (SBRT) may improve outcomes by delivering ablative radiation doses.

Methods: We reviewed patients who received definitive-intent SBRT reirradiation at our institution from 2013 to 2020.

Evaluating the Soft Tissue Sarcoma Paradigm for the Local Management of Extraskeletal Ewing Sarcoma.

Objectives: We reviewed our experience treating patients with localized extraskeletal Ewing sarcoma (EES) to determine optimal local management strategies for this rare disease.

Methods: Sixty patients with localized EES treated at our institution between 1994 and 2018 were reviewed. The Kaplan-Meier method was used to estimates disease outcomes.

Low risk of radiation myelopathy with relaxed spinal cord dose constraints in de novo, single fraction spine stereotactic radiosurgery.

Background And Purpose: Spine stereotactic radiosurgery (SSRS) offers high rates of local control in a critical anatomic area by delivering precise, ablative doses of radiation for treatment of spine metastases. However, the dose tolerance of the spinal cord (SC) after SSRS with relation to radiation myelopathy (RM) is not well-described.

Materials And Methods: We reviewed patients who underwent single fraction, de novo SSRS from 2012-2017 and received >12 Gy Dmax to the SC, defined using MRI-CT fusion without PRV expansion.

Effect of Surgeon Factors on Long-Term Patient-Reported Outcomes After Breast-Conserving Therapy in Older Breast Cancer Survivors.

Background: The effect of surgeon factors on patient-reported quality-of-life outcomes after breast-conserving therapy (BCT) is unknown and may help patients make informed care decisions.

Methods: We performed a survey study of women aged ≥ 67 years with non-metastatic breast cancer diagnosed in 2009 and treated with guideline-concordant BCT, to determine the association of surgeon factors with patient-reported outcomes. The treating surgeon was identified using Medicare claims, and surgeon factors were identified via the American Medical Association Physician Masterfile.

Impact of Positive Margins and Radiation After Tracheal Adenoid Cystic Carcinoma Resection on Survival.

Background: Achieving negative margins for adenoid cystic carcinoma (ACC) of the trachea can be technically difficult. This study evaluated the impact of positive margins on prognosis and tested the hypothesis that radiation improves survival in the setting of incomplete resection.

Methods: The impact of margin status and adjuvant therapy on overall survival of patients with tracheal ACC in the National Cancer Database (1998 to 2014) who underwent resection with known margin status and with no documented nodal or distant disease was evaluated using Kaplan-Meier and Cox proportional hazard analysis.

Stereotactic radiosurgery and ipilimumab for patients with melanoma brain metastases: clinical outcomes and toxicity.

Introduction: There is evidence that the combination of ipilimumab and stereotactic radiosurgery (SRS) for brain metastases improves outcomes. We investigated clinical outcomes, radiation toxicity, and impact of ipilimumab timing in patients treated with SRS for melanoma brain metastases.

Methods: We retrospectively identified 91 patients treated with SRS at our institution for melanoma brain metastases from 2006 to 2015.

The growing importance of lesion volume as a prognostic factor in patients with multiple brain metastases treated with stereotactic radiosurgery.

Stereotactic Radiosurgery (SRS) is considered standard of care for patients with 1-3 brain metastases (BM). Recent observational studies have shown equivalent OS in patients with 5+ BM compared to those with 2-4, suggesting SRS alone may be appropriate in these patients. We aim to review outcomes of patients treated with SRS with 2-4 versus 5+ BM.

Combination ipilimumab and radiosurgery for brain metastases: tumor, edema, and adverse radiation effects.

OBJECTIVETumor and edema volume changes of brain metastases after stereotactic radiosurgery (SRS) and ipilimumab are not well described, and there is concern regarding the safety of combination treatment. The authors evaluated tumor, edema, and adverse radiation-induced changes after SRS with and without ipilimumab and identified associated risk factors.METHODSThis single-institution retrospective study included 72 patients with melanoma brain metastases treated consecutively with upfront SRS from 2006 to 2015.

Radiation toxicity in patients with collagen vascular disease and intrathoracic malignancy treated with modern radiation techniques.

Background And Purpose: There is concern that patients with collagen vascular disease (CVD) are at higher risk of developing radiation toxicity. We analyzed radiation toxicities in patients with intrathoracic malignancy and CVD treated using modern radiotherapy.

Materials And Methods: This single-institution retrospective study included 31 patients with CVD and 825 patients without CVD treated from 1998 to 2014.
