Eye Plaque Brachytherapy for Choroidal Malignant Melanoma: A Case Report on the Use of Innovative Technology to Expand Access, Improve Practice, and Enhance Outcomes.

Our institute established an eye plaque interstitial brachytherapy (EPIBT) program in 2007 using the Collaborative Ocular Melanoma Study (COMS) eye plaque. In this case report, we demonstrated an eye plaque treatment planned and executed using Eye Physics Plaque (Los Alamitos, CA) for a 72-year-old male patient with an extra-large tumor with a maximum width of 18.6 mm and height of 13.7 mm. The use of a customized eye plaque, manufactured through three-dimensional (3D) printing, has empowered us to plan and administer treatment for this patient with uveal melanoma. Without this option, enucleation, an option declined by the patient, or proton beam therapy (PBT), which the patient was unwilling to pursue in another state, would have been the alternative course of action. We were able to use more than one activity of the I-125 seeds, which enabled us to shape and reduce the dose to normal surrounding structures at risk within the orbit and in the vicinity of the orbital cavity. Using the dose evaluation tools available with the modern treatment planning system, we reduced the prescription dose from 85 to 70 Gy, with D90 of 140 Gy, thereby providing effective treatment and limiting risk organ doses. In summary, we were able to dose-deescalate without compromising the chances of controlling retinal/scleral tumors. The patient is doing well from a recent follow-up visit 12 months after the eye plaque brachytherapy treatment. The tumor was 4.80 mm high, 1/3 of the original height, and vision is back to 20/60, demonstrating a successful treatment.

Real World and Public Health Perspectives of Intraoperative Radiotherapy in Early-Stage Breast Cancer: A Multidisciplinary Analysis Beyond the Statistical Facts.

Breast conservation therapy (BCT) (usually a lumpectomy plus radiotherapy (RT)) has become a standard alternative to radical mastectomy in early-stage breast cancers with equal, if not higher, survival rates. The established standard of the RT component of the BCT had been about six weeks of Monday through Friday external beam RT to the whole breast (WBRT). Recent clinical trials have shown that partial breast radiation therapy (PBRT) to the region surrounding the lumpectomy cavity with shorter courses can result in equal local control, survival, and slightly improved cosmetic outcomes. Intraoperative RT (IORT) wherein RT is administered at the time of operation for BCT to the lumpectomy cavity as a single-fraction RT is also considered PBRT. The advantage of IORT is that weeks of RT are avoided. However, the role of IORT as part of BCT has been controversial. The extreme views go from "I will not recommend to anyone" to "I can recommend to all early-stage favorable patients." These divergent views are due to difficulty in interpreting the clinical trial results. There are two modalities of delivering IORT, namely, the use of low-energy 50 kV beams or electron beams. There are several retrospective, prospective, and two randomized clinical trials comparing IORT versus WBRT. Yet, the opinions are divided. In this paper, we try to bring clarity and consensus from a highly broad-based multidisciplinary team approach. The multidisciplinary team included breast surgeons, radiation oncologists, medical physicists, biostatisticians, public health experts, nurse practitioners, and medical oncologists. We show that there is a need to more carefully interpret and differentiate the data based on electron versus low-dose X-ray modalities; the randomized study results have to be extremely carefully dissected from biostatistical points of view; the importance of the involvement of patients and families in the decision making in a very transparent and informed manner needs to be emphasized; and the compromise some women may be willing to accept between 2-4% potential increase in local recurrence (as interpreted by some of the investigators in IORT randomized studies) versus mastectomy. We conclude that, ultimately, the choice should be that of women with detailed facts of the pros and cons of all options being presented to them from the angle of patient/family-focused care. Although the guidelines of various professional societies can be helpful, they are only guidelines. The participation of women in IORT clinical trials is still needed, and as genome-based and omics-based fine-tuning of prognostic fingerprints evolve, the current guidelines need to be revisited. Finally, the use of IORT can help rural, socioeconomically, and infrastructure-deprived populations and geographic regions as the convenience of single-fraction RT and the possibility of breast preservation are likely to encourage more women to choose BCT than mastectomy. This option can also likely lead to more women choosing to get screened for breast cancer, thus enabling the diagnosis of breast cancer at an earlier stage and improving the survival outcomes.

Patients and Families' Participation in Multidisciplinary Tumor Conferences Improves Patient and Family-Focused Cancer Care: Lessons Learned From a Debate on the Role of Radiation Therapy in Primary Mediastinal Non-Hodgkin Lymphoma.

Incorporation of patients' preferences often leads to improved outcomes when included in the multidisciplinary tumor conference/board (MTC). However, patients' wishes are not included or considered in the MTC decision-making. We need better strategies and approaches for patient-inclusive, shared decision-making. When finding ourselves at a crossroads regarding the next step in a patient's treatment, we saw a unique opportunity for an MTC with the patient and her husband in attendance. The results of a full literature review regarding the role of consolidative radiation therapy (RT) in a patient with primary (thymic) B-cell lymphoma after completion of chemotherapy and fluorodeoxyglucose positron emission tomography-computed tomography (FDG-PET/CT) scan with a Deauville score of 4 were presented in a creative, engaging debate-style forum with visual aids. The patient and her husband were able to follow the discussion and, in the end, a consensus recommendation, heavily focused on the patient's preferences, was offered and adopted, which ultimately resulted in the avoidance of excess treatment and likely improved her long-term quality of life outcome. These collaborative and innovative interactions benefit not only our patients but enrich our lives too as healthcare providers and strengthen us as a cancer care team in terms of understanding diversity in decision-making processes.

MRI-Directed Brachytherapy for Cancer of the Uterine Cervix: A Case Report, Review, and Perspective on the Importance of Widespread Use of This Technological Advance in the United States.

Cervical cancer remains a major health challenge in the United States (US), especially among the low socioeconomic and African American populations. The demographics of Mississippi constitute a relatively high percentage of this high-risk population. External beam radiation therapy (EBRT) combined with concurrent chemotherapy and followed by brachytherapy is the gold standard of treatment for stage IB3 through IVA cervical cancer. Arguably, brachytherapy is the most important component of this treatment process. Patterns of Care studies (PCS) and other more recent studies have shown that brachytherapy cannot be omitted or replaced by conventional or image-guided EBRT. The last decade has witnessed the expanding use of image-guided brachytherapy (IGBT). Studies have established the superiority of IGBT over point-based brachytherapy. MRI is associated with superior soft tissue definition compared with CT and is emerging as the new standard of care. The Gynaecological Groupe Européen de Curiethérapie and the European Society for Radiotherapy and Oncology [(GYN) GEC-ESTRO] have recommended that the dose be prescribed to the high-risk clinical target volume (HR-CTV). This volume includes residual tumor present at the time of brachytherapy, the cervix, and any gray areas seen on the scan. The (GYN) GEC-ESTRO has shown that a dose of >8500 cGy delivered in <50 days results in an approximate 10% increase in pelvic control (PC), disease-specific survival, and overall survival (OS) compared to historical controls. The normal tissue toxicity is comparable or better than historical controls as well. This dose, while maintaining normal tissue constraints, may only be achievable with a hybrid intracavitary/interstitial (IC/IS) needle device guided by MRI-based targeting.  The University of Mississippi Medical Center (UMMC) has initiated an MRI-based cervical brachytherapy program and has treated 18 patients to date; our experience confirms the above findings. In this report, we propose that MRI guidance is necessary and a hybrid IC/IS needle device is required to achieve adequate dose coverages.

A 25-year Experience at an Academic Medical Center in the United States: Are There Racial Disparities in the Prognosis of Patients Diagnosed With Hypopharyngeal Carcinoma?

Introduction This study attempted to identify disparities in outcomes between African American (AA) and Caucasian American (CA) patients treated for hypopharyngeal carcinoma at a tertiary care institution over the past 25 years. Methods An institutional review board (IRB)-approved and Health Insurance Portability and Accountability Act (HIPPA)-compliant retrospective analysis was performed on patients with squamous cell carcinoma of the hypopharynx treated at our institution between January 1994 and December 2018. Data regarding demographics, stage, treatment, and follow-up were collected. Outcomes, including median survival and overall survival, were calculated using the Kaplan-Meier method. All analyses were performed using the Social Packages for the Social Sciences (SPSS) v. 24 (IBM Corp., Armonk, NY). Results We identified 144 hypopharyngeal carcinoma patients who were treated during this period. Our patient cohort consisted of 61.8% AA and 35.4% CA (P=0.538). Overall, 96% of them presented at an advanced stage (Stages III & IV) of the disease, and only 4% presented in the early stages (Stages I & II). There was no significant difference between AA and CA patients who presented with advanced disease (96.6% vs. 94.1%). In our patient cohort, 15.3% of patients did not receive any therapy; however, 51.4%, 22.9%, and 10.4% of them underwent definitive chemoradiotherapy, definitive surgery, or palliative chemotherapy, respectively. There were no significant differences in patient racial proportions within each treatment group. The median follow-up of the entire cohort was 13 months. There was no significant difference between the median survival of AA and that of CA patients (16 months vs. 15 months; p=0.917). Moreover, there was no significant difference in the overall survival between AA and CA patients at three years (27.2% vs. 36.3%; p=0.917) and five years (20.4 % vs. 16.7 %; p=0.917). Conclusions A retrospective review of patients with hypopharyngeal cancer treated at our institution over the previous 25 years did not identify significant racial disparities regarding the stage at presentation or prognosis. This study suggests that when patients have equal access to care, they appear to have a similar prognosis despite racial differences. Further studies are needed to validate this hypothesis.

The pervasive crisis of diminishing radiation therapy access for vulnerable populations in the United States-Part 4: Appalachian patients.

PURPOSE: Compared with the rest of the United States, the population of Appalachia has lower education levels, higher rates of poverty, and limited access to health care. The presence of disparities in radiation therapy (RT) access for Appalachian patients with cancer has rarely been examined. METHODS AND MATERIALS: The National Cancer Institute initiatives toward addressing disparities in treatment access for rural populations were examined. An extensive literature search was undertaken for studies investigating RT access disparities in Appalachian patients, beginning with the most common cancers in these patients (lung, colorectal, and cervical). RESULTS: Although the literature investigating RT access disparities in Appalachia is relatively sparse, studies examining lung, colorectal, cervical, prostate, head and neck, breast, and esophageal cancer, as well as lymphoma, indicate an unfortunate commonality in barriers to optimal RT access for Appalachian patients with cancer. These barriers are predominantly socioeconomic in nature (low income and lack of private insurance) but are exacerbated by paucities in both the number and quality of radiation centers that are accessible to this patient population. CONCLUSIONS: Regardless of organ system, there are significant barriers for Appalachian patients with cancer to receive RT. Such diminished access is alarming and warrants resources devoted to addressing these disparities, which often go overlooked because of the assumption that the overall wealth of the United States is tangibly applicable to all of its citizens. Without intelligently targeted investments of time and finances in this arena, there is great risk of exacerbating rather than alleviating the already heavy burden facing Appalachian patients with cancer.

Guideline-concordant Care Improves Overall Survival for Locally Advanced Non-Small-cell Lung Carcinoma Patients: A National Cancer Database Analysis.

BACKGROUND: Current evidence-based guideline-concordant care (GCC) for locally advanced non-small-cell lung cancer (NSCLC) patients with good performance status is concurrent chemoradiation. In this study we evaluated factors associated with lack of GCC and its effects on overall survival (OS). PATIENTS AND METHODS: Unresectable stage III NSCLC patients, diagnosed from 2005 to 2013 with a Charlson-Deyo score of 0, were identified from the National Cancer Database. Primary outcomes were receipt of GCC, defined as concurrent chemoradiation (thoracic radiotherapy, starting within 2 weeks of chemotherapy, to at least 60 Gy), and OS. Multivariable logistic regression modeling identified variables associated with non-GCC. Cox proportional hazard modeling was used to examine OS. RESULTS: Twenty-three percent of patients (n = 10,476) received GCC. Uninsured patients were more likely to receive non-GCC (odds ratio [OR], 1.54; P < .001) compared with privately insured patients. Other groups with greater odds of receiving non-GCC included: patients treated in the western, southern, or northeastern United States (ORs, 1.39, 1.37, and 1.19, respectively; all Ps < .001) compared with the Midwest; adenocarcinoma histology (OR, 1.48; P < .001) compared with squamous cell carcinoma; and women (OR, 1.08; P = .002). Those who received non-GCC had higher death rates compared with those who received GCC (hazard ratio [HR], 1.42; P < .001). The uninsured (HR, 1.53; P < .001), patients treated in the western, southern, or northeastern United States (HRs, 1.56, 1.41, and 1.34, respectively; P < .001), adenocarcinomas (HR, 1.39; P < .001), and women (HR, 1.44; P < .001) also all had lower OS for non-GCC versus GCC. CONCLUSION: Socioeconomic factors, including lack of insurance and geography, are associated with non-GCC. Patient- and disease-specific factors, including increasing adenocarcinoma histology and sex, are also associated with non-GCC. Non-GCC diminishes OS.
