Radiation Therapy for Primary Cutaneous Gamma Delta Lymphoma Prior to Stem Cell Transplantation.
Cancer investigation
2021: 1–11
Abstract
We present a patient with widespread PCGD-TCL of the bilateral arms and legs, who underwent radiotherapy with 34Gy in 17 fractions using circumferential VMAT and 3-D printed bolus to the 4 extremities prior to planned stem cell transplant, who was then found to have progression in the liver, lung, and skin, followed by drastic regression of all in and out-of-field lesions on imaging 1.5months later. The cause of regression may be related to a radiation-induced abscopal effect from the immunomodulatory effects of radiation, or related to immune reactivation in the setting of cessation of systemic immunosuppressive agents.

The impact of postoperative therapy on primary cardiac sarcoma.
The Journal of thoracic and cardiovascular surgery
2018; 156 (6): 2194-2203
Abstract
Primary cardiac sarcomas (PCS) are extremely rare, portend a very poor prognosis, and have limited outcomes data to direct management. This study evaluated the impact of postoperative chemotherapy and/or radiotherapy on survival for PCS.A retrospective chart review was conducted of 12 patients diagnosed with and who underwent resection for PCS at a single institution between 2000 and 2016. Data were collected on patient/tumor characteristics and analyzed with respect to treatment and outcome using Kaplan-Meier methods.Median age was 43 (range 21-73 years) with a 50:50 male-to-female ratio. The most common subtype was angiosarcoma (42%), and 25% presented with distant metastases (DMs). The initial treatment modality for all patients was surgery, with 58% having macroscopically positive (R2) margins. In total, 75% received postoperative chemotherapy and/or radiotherapy. Median progression-free survival (PFS) was 5.9 months, and median overall survival (OS) was 12.0 months. Achieving negative or microscopically positive margins (R0/R1) as compared with R2 resection significantly improved PFS (12.6 vs 2.7 months, P = .008) and OS (21.8 vs 7.2 months, P = .006). DM at presentation demonstrated a significantly shorter OS (7.0 vs 16.9 months, P = .04) and PFS (0.7 vs 7.9 months, P = .003) compared with localized disease. Patients given postoperative therapy had longer OS compared with surgery only, but this difference was not statistically significant (15.5 vs 2.6 months, P = .12).Gross total surgical resection can significantly improve PFS and OS in PCS, but DM at diagnosis is an extremely poor prognostic sign. Postoperative therapy should be considered, although this study was likely underpowered to demonstrate a statistically significant benefit.

Patient-Centered Care Challenges and Surprises: Through the Clerkship Students' Eyes.
Family medicine
2017; 49 (1): 57-61
Abstract
The patient-centered care model for health care delivery encourages medical providers to respect patients' preferences and give patients more autonomy over their health care decisions. This approach has gained importance within US medical school curricula. Yet, little is known about student perspectives on both patient-centered care and the benefits and challenges that lie therein. This manuscript explores the greatest impediments to, as well as the benefits from, student engagement in patient-centered care from the perspectives of students participating in their family medicine outpatient clerkship.Clerkship students on their core family medicine clerkship at Stanford University School of Medicine were provided the following open-ended prompt: "Describe a patient-centered care challenge or surprise in the family medicine core clerkship." Free-text responses were collected and analyzed using content and thematic analysis.A total of 326 responses from 216 students were analyzed for frequency and patient-centered themes. Nine final themes emerged and were grouped into three domains: student definitions of patient-centered care, patient-centered care impact on patients, and patient-centered care impact on medical professionals.Our study suggests that students find the patient-centered care model for health care delivery to be challenging but worthwhile. We highlight that students find communication with patients in a patient-centered manner challenging and discuss the need for improved medical education about patient-centered care in order to better prepare students to implement the model in a variety of psychosocial and medical contexts.

Predictors of Toxicity Associated With Stereotactic Body Radiation Therapy to the Central Hepatobiliary Tract
INTERNATIONAL JOURNAL OF RADIATION ONCOLOGY BIOLOGY PHYSICS
2015; 91 (5): 986-994
Abstract
To identify dosimetric predictors of hepatobiliary (HB) toxicity associated with stereotactic body radiation therapy (SBRT) for liver tumors.We retrospectively reviewed 96 patients treated with SBRT for primary (53%) or metastatic (47%) liver tumors between March 2006 and November 2013. The central HB tract (cHBT) was defined by a 15-mm expansion of the portal vein from the splenic confluence to the first bifurcation of left and right portal veins. Patients were censored for toxicity upon local progression or additional liver-directed therapy. HB toxicities were graded according to Common Terminology Criteria for Adverse Events version 4.0. To compare different SBRT fractionations, doses were converted to biologically effective doses (BED) by using the standard linear quadratic model α/β = 10 (BED10).Median follow-up was 12.7 months after SBRT. Median BED10 was 85.5 Gy (range: 37.5-151.2). The median number of fractions was 5 (range: 1-5), with 51 patients (53.1%) receiving 5 fractions and 29 patients (30.2%) receiving 3 fractions. In total, there were 23 (24.0%) grade 2+ and 18 (18.8%) grade 3+ HB toxicities. Nondosimetric factors predictive of grade 3+ HB toxicity included cholangiocarcinoma (CCA) histology (P<.0001), primary liver tumor (P=.0087), and biliary stent (P<.0001). Dosimetric parameters most predictive of grade 3+ HB toxicity were volume receiving above BED10 of 72 Gy (VBED1072) ≥ 21 cm(3) (relative risk [RR]: 11.6, P<.0001), VBED1066 ≥ 24 cm(3) (RR: 10.5, P<.0001), and mean BED10 (DmeanBED10) cHBT ≥14 Gy (RR: 9.2, P<.0001), with VBED1072 and VBED1066 corresponding to V40 and V37.7 for 5 fractions and V33.8 and V32.0 for 3 fractions, respectively. VBED1072 ≥ 21 cm(3), VBED1066 ≥ 24 cm(3), and DmeanBED10 cHBT ≥14 Gy were consistently predictive of grade 3+ toxicity on multivariate analysis.VBED1072, VBED1066, and DmeanBED10 to cHBT are associated with HB toxicity. We suggest VBED1072 < 21 cm(3) (5-fraction: V40 < 21 cm(3); 3-fraction: V33.8 < 21 cm(3)), VBED1066 < 24 cm(3) (5-fraction: V37.7 < 24 cm(3); 3-fraction: V32 < 24 cm(3)) as potential dose constraints for the cHBT when clinically indicated.

Statin-associated Autoimmune Myopathies: A Pathophysiologic Spectrum
CANADIAN JOURNAL OF NEUROLOGICAL SCIENCES
2014; 41 (5): 638-647
Abstract
Statins have recently been reported to cause a rare autoimmune inflammatory and/or necrotic myopathy that begins or persists after drug cessation.We report on 26 patients seen at a neuromuscular centre between 2005 and 2011 who demonstrated muscle weakness/myalgias and creatine kinase elevations during or after statin treatment with continuation of signs and symptoms despite statin withdrawal.All patients were treated with immunosuppressive therapy with good response; all improved biochemically and 86% improved clinically. Sixty-five percent of patients who attempted to taper off immunosuppressive therapy relapsed. We report on a novel finding whereby five of the seven patients who underwent multiple biopsies throughout their disease demonstrated a transformation of their histological diagnosis, with four progressing from having myofibre necrosis with minimal or no inflammation to a diagnosis of polymyositis.This study offers preliminary evidence that statin-associated necrotizing myopathy and statin-associated polymyositis may not be separate entities but are part of the same pathophysiological spectrum. Both entities respond well to immunosuppression.

Six novel mutations in the myophosphorylase gene in patients with McArdle disease and a family with pseudo-dominant inheritance pattern
MOLECULAR GENETICS AND METABOLISM
2011; 104 (4): 587-591
Abstract
McArdle disease is an autosomal recessive glycogenosis due to deficiency of the enzyme myophosphorylase. It results from homozygous or compound heterozygous mutations in the gene for this enzyme, PYGM. We report six novel mutations in the PYGM gene based upon sequencing data including three missense mutations (p.D51G, p.P398L, and p.N648Y), one nonsense mutation (p.Y75X), one frame-shift mutation (p.Y114SfsX181), and one amino acid deletion (p.Y53del) in six patients with McArdle disease. We also report on a Caucasian family that appeared to transmit McArdle disease in an autosomal dominant manner. In order to evaluate the potential pathogenicity of the sequence variants, we performed in silico analysis using PolyPhen-2 and SIFT BLink, along with species conservation analysis using UCSC Genome Browser. The above mutations were all predicted to be disease associated with high probability and with at least the same level of certainty as several confirmed mutations. The current data add to the list of pathogenic mutations in the PYGM gene associated with McArdle disease.
