1.  Dendritic cell therapy in melanoma 
Dendritic cell (DC) vaccines are cancer vaccines used currently as melanoma therapies. They act as adjuvants initiating the immune responses, but not only as they can also have effector activities redirecting cytotoxic CD8+ T cells against melanoma. Ex vivo preparation of monocyte derived DCs has been implemented to produce large numbers of DCs for clinical therapy, highlighting the necessity of activate DC s to produce Th1 cytokines, especially TNF-a and IL-12 with potent anti-tumour actions. Several clinical trials both in the European Union and USA are open currently using DC vaccines, alone or in combination with other immunotherapies. The type of antigen is also an active area of investigation involving tumour antigens and bacterial epitopes, both providing good responses. Bacterial epitopes presented the advantage versus tumour antigens that they can prepare the vaccination site as they induce innate and specific immune responses as they are potent recall antigens that expand cytotoxic responses.

3.  Procedural techniques and multicenter postmarket experience using minimally invasive convective radiofrequency thermal therapy with Rezūm system for treatment of lower urinary tract symptoms due to benign prostatic hyperplasia 
This report evaluates clinical experience with the Rezūm system after US Food and Drug Administration clearance in consecutive cases accrued by multiple community urologists for the treatment of lower urinary tract symptoms (LUTS) associated with benign prostatic hyperplasia (BPH). Treatment techniques for transurethral convective radiofrequency water-vapor thermal therapy and outcomes with up to 12 months’ follow-up are presented.
Materials and methods
A total of 131 patients with moderate–severe LUTS were included in a retrospective analysis of BPH procedures with the Rezūm system. Pre- and postprocedure assessments included International Prostate Symptom Score (IPSS), quality of life, peak urinary flow rate, voided volume, and postvoid residual urine volume. Urologists used their own discretion for patient selection, with variable prostate sizes, LUTS severity, urinary retention, or presence of an obstructing median lobe. Safety signals and surgical retreatment rates were monitored prospectively.
Men aged 47–96 years with prostates 13–183 cm3 showed significant improvement in IPSS, quality of life, and postvoid residual volume durable through 12 months after thermal therapy. Patients with either moderate (IPSS 8–19) or severe (IPSS 20–35) symptoms achieved significantly improved scores. Postprocedure adverse events normally anticipated and related to endoscopic instrumentation were transient and mild–moderate in nature. No de novo erectile or ejaculatory dysfunction was reported.
This study corroborates prior published pilot and randomized controlled trial results indicating significant relief of urinary symptoms and reproducibility of responses to thermal therapy. Convective radiofrequency thermal therapy with the Rezūm system warrants consideration as a first-line treatment for LUTS/BPH as an alternative to the use of pharmaceutical agents.

4.  GNP-GAPDH1-22 nanovaccines prevent neonatal listeriosis by blocking microglial apoptosis and bacterial dissemination 
Oncotarget  2017;8(33):53916-53934.
Clinical cases of neonatal listeriosis are associated with brain disease and fetal loss due to complications in early or late pregnancy, which suggests that microglial function is altered. This is believed to be the first study to link microglial apoptosis with neonatal listeriosis and listeriosis-associated brain disease, and to propose a new nanovaccine formulation that reverses all effects of listeriosis and confers Listeria monocytogenes (LM)-specific immunity. We examined clinical cases of neonatal listeriosis in 2013–2015 and defined two useful prognostic immune biomarkers to design listeriosis vaccines: high anti-GAPDH1-22 titres and tumor necrosis factor (TNF)/interleukin (IL)-6 ratios. Therefore, we developed a nanovaccine with gold glyco-nanoparticles conjugated to LM peptide 1-22 of GAPDH (Lmo2459), GNP-GAPDH1-22 nanovaccinesformulated with a pro-inflammatory Toll-like receptor 2/4-targeted adjuvant. Neonates born to non-vaccinated pregnant mice with listeriosis, showed brain and vascular diseases and significant microglial dysfunction by induction of TNF-α-mediated apoptosis. This programmed TNF-mediated suicide explains LM dissemination in brains and livers and blocks production of early pro-inflammatory cytokines such as IL-1β and interferon-α/β. In contrast, neonates born to GNP-GAPDH1–22-vaccinated mothers before LM infection, did not develop listeriosis or brain diseases and had functional microglia. In nanovaccinated mothers, immune responses shifted towards Th1/IL-12 pro-inflammatory cytokine profiles and high production of anti-GAPDH1–22 antibodies, suggesting good induction of LM-specific memory.

5.  Is a Wider Margin (2 cm vs. 1 cm) for a 1.01–2.0 mm Melanoma Necessary? 
Annals of surgical oncology  2016;23(7):2336-2342.
The current NCCN recommendation for resection margins in patients with melanomas between 1.01–2 mm deep is a 1–2 cm radial margin. We sought to determine if margin width had an impact on local recurrence (LR), disease-specific survival (DSS), and type of wound closure.
1.01–2.0 mm melanomas were evaluated at a single institution between 2008 and 2013. All patients had a 1 or 2 cm margin.
We identified 965 patients that had a 1 cm (n=302, 31.3%) or 2 cm margin (n=663, 68.7%). Median age was 64 and 592 (61.3%) were male. 32.5% and 48.7% of head and neck and extremity patients had a 1 cm margin vs. 18.9% of trunk pts (p<0.001). LR was 0.6% and 1.5% for a 1 and 2 cm margin, respectively (p=NS). Five-year DSS was 87% for a 1 cm margin and 85% for a 2 cm margin (p=NS). Breslow thickness, melanoma on the head and neck, lymphovascular invasion (LVI) and sentinel lymph node biopsy (SLNB) status significantly predicted LR on univariate analysis, however only location and SLNB status were associated with LR on multivariate analysis. Margin width was not significant for LR or DSS. Wider margins were associated with more frequent graft or flap use only on the head and neck (p=0.025).
Our data show selectively using a narrow margin of 1 cm did not increase the risk of local recurrence or decrease DSS. Avoiding a 2 cm margin may decrease the need for graft/flap use on the head and neck.

6.  Perspective on the Rezūm® System: a minimally invasive treatment strategy for benign prostatic hyperplasia using convective radiofrequency water vapor thermal therapy 
Convective radiofrequency (RF) water vapor thermal therapy is a minimally invasive office or outpatient procedure for the treatment of bothersome moderate-to-severe lower urinary tract symptoms associated with benign prostatic hyperplasia (BPH). It provides an option for patients seeking rapid and durable relief of urinary symptoms, improved quality of life, and preservation of sexual function as an alternative to long-term use of drugs and avoidance of the potential side effects of pharmaceuticals or invasive BPH surgery. The procedure is also applicable for the treatment of the median lobe or elevated bladder neck from central zone hyperplasia. This perspective presents a comprehensive overview of the Rezūm® System convective RF thermal therapy device, the principles upon which it is based, the operative procedure, and the clinical evidence accrued to this point in time.

7.  Myoepithelial carcinoma with RB1 mutation: remarkable chemosensitivity to carcinoma of unknown origin therapy 
BMC Cancer  2017;17:250.
Myoepithelial carcinoma of soft tissue is a rare, malignant neoplasm that is morphologically and immunophenotypically similar to its counterpart in salivary gland. It demonstrates myoepithelial differentiation, possessing both epithelial and myogenic characteristics. Thought to be chemotherapy insensitive, the optimal treatment regimen of this tumor has yet to be established and only a select few cases in the literature discuss treatment efficacy in detail.
Case presentation
Here we present a case of a young adult with metastatic myoepithelial carcinoma with an initial excellent response to systemic therapy utilizing carboplatin and paclitaxel with continued complete response after 3 years. The patient also underwent complete surgical excision and received adjuvant radiation to the primary site of disease. Exome sequencing revealed an inactivating mutation in RB1 which we believe to be the first such mutation to be reported in this cancer type.
Given increasing evidence suggesting RB1 loss is associated with responsiveness to conventional chemotherapies, particularly platinum-based regimens, we hypothesize that this genetic feature predisposed chemosensitivity in our patient’s tumor.

8.  Staged reconstruction brachytherapy has lower overall cost in recurrent soft-tissue sarcoma 
Adjuvant brachytherapy (AB) with immediate (IR) and staged reconstruction (SR) are distinct treatment modalities available for patients with recurrent soft tissue sarcoma (STS). Although SR may offer local control and toxicity benefit, it requires additional upfront procedures, and there is no evidence that it improves overall survival. With the importance of value-based care, our goal is to identify which technique is more cost effective.
Material and methods
A retrospective review of 22 patients with recurrent extremity STS treated with resection followed by AB alone. Hospital charges were used to compare the cost between SR and IR at the time of initial treatment, at 6-month intervals following surgery, and cumulative cost comparisons at 18 months.
Median follow-up was 31 months. Staged reconstruction (n = 12) was associated with an 18-month local control benefit (85% vs. 42%, p = 0.034), compared to IR (n = 10). Staged reconstruction had a longer hospital stay during initial treatment (10 vs. 3 days, p = 0.002), but at 18 months, the total hospital stay was no longer different (11 vs. 11 days). Initially, there was no difference in the cost of SR and IR. With longer follow-up, cost eventually favored SR, which was attributed primarily to the costs associated with local failure (LF). On multivariate analysis, cost of initial treatment was associated with length of hospital stay (~$4.5K per hospital day, p < 0.001), and at 18 months, the cumulative cost was ~175K lower with SR (p = 0.005) and $58K higher with LF (p = 0.02).
In recurrent STS, SR has a longer initial hospital stay when compared to IR. At 18 months, SR had lower rates of LF, translating to lower total costs for the patient. SR is the more cost-effective brachytherapy approach in the treatment of STS, and should be considered as healthcare transitions into value-based medicine.

9.  Dermal Melanoma: A Report on Prognosis, Outcomes, and the Utility of Sentinel Lymph Node Biopsy 
Journal of surgical oncology  2015;113(1):98-102.
Historically dermal melanoma (DM) has been labeled as either stage IIIB (in-transit) or stage IV (M1a) disease. We sought to investigate the natural history of DM and the utility and prognostic significance of sentinel lymph node biopsy (SLNB).
Patients with DM undergoing SLNB at a single center from 1998 to 2009 were identified.
Eighty-three patients met criteria, 10 (12%) patients had a positive SLNB. Of those, 5 (50%) recurred (all with distant disease). Twenty-one (29%) of the 73 SLNB negative patients recurred and of those, 15 (71%) developed distant metastases, whereas 6 (29%) developed local or regional recurrence, including two false-negative regional nodal recurrences. No in-transit recurrences were recorded. Five-year recurrence-free and disease-specific survival was significantly better for patients with a negative SLNB versus positive SLNB (56.8% vs. 22.2% P =0.02, 81.1% vs. 61.0%, P =0.05, respectively).
SLNB has prognostic significance for RFS and DSS, and should be utilized in the management of DM based on a >10% yield and low false-negative rate. Our data demonstrate patients with DM do not recur in an in-transit fashion, which along with the survival outcomes suggest the behavior of DM is consistent with primary cutaneous melanoma of similar thickness rather than an isolated in-transit or distant dermal metastasis from a regressed cutaneous primary.

11.  Genomic copy number variation association study in Caucasian patients with nonsyndromic cryptorchidism 
BMC Urology  2016;16:62.
Copy number variation (CNV) is a potential contributing factor to many genetic diseases. Here we investigated the potential association of CNV with nonsyndromic cryptorchidism, the most common male congenital genitourinary defect, in a Caucasian population.
Genome wide genotyping were performed in 559 cases and 1772 controls (Group 1) using Illumina HumanHap550 v1, HumanHap550 v3 or Human610-Quad platforms and in 353 cases and 1149 controls (Group 2) using the Illumina Human OmniExpress 12v1 or Human OmniExpress 12v1-1. Signal intensity data including log R ratio (LRR) and B allele frequency (BAF) for each single nucleotide polymorphism (SNP) were used for CNV detection using PennCNV software. After sample quality control, gene- and CNV-based association tests were performed using cleaned data from Group 1 (493 cases and 1586 controls) and Group 2 (307 cases and 1102 controls) using ParseCNV software. Meta-analysis was performed using gene-based test results as input to identify significant genes, and CNVs in or around significant genes were identified in CNV-based association test results. Called CNVs passing quality control and signal intensity visualization examination were considered for validation using TaqMan CNV assays and QuantStudio® 3D Digital PCR System.
The meta-analysis identified 373 genome wide significant (p < 5X10−4) genes/loci including 49 genes/loci with deletions and 324 with duplications. Among them, 17 genes with deletion and 1 gene with duplication were identified in CNV-based association results in both Group 1 and Group 2. Only 2 genes (NUCB2 and UPF2) containing deletions passed CNV quality control in both groups and signal intensity visualization examination, but laboratory validation failed to verify these deletions.
Our data do not support that structural variation is a major cause of nonsyndromic cryptorchidism.

12.  Both Tumor Depth and Diameter Are Predictive of Sentinel Lymph Node Status and Survival in Merkel Cell Carcinoma 
Cancer  2015;121(18):3252-3260.
The purposes of this study were 1) to determine the impact of primary tumor-related factors on the prediction of the sentinel lymph node (SLN) status and 2) to identify clinical and pathologic factors associated with survival in Merkel cell carcinoma (MCC).
An institutional review board–approved, retrospective review of patients with MCC treated between 1988 and 2011 at a single center was performed. Patients were categorized into 5 groups: 1) negative SLN, 2) positive SLN, 3) clinically node-negative but SLN biopsy not performed, 4) regional nodal disease without a known primary tumor, and 5) primary MCC with synchronous clinically evident regional nodal disease. Factors predictive of the SLN status were analyzed with logistic regressions, and overall survival (OS) and disease-specific survival (DSS) were analyzed with Cox models and competing risk models assuming proportional hazards, respectively.
Three hundred seventy-five patients were analyzed, and 70% were male; the median age was 75 years. The median tumor diameter was 1.5 cm (range, 0.2–12.5 cm), and the median tumor depth was 4.8 mm (range, 0.3–45.0 mm). One hundred ninety-one patients underwent SLN biopsy, and 59 (31%) were SLN-positive. Increasing primary tumor diameter and increasing tumor depth were associated with SLN positivity (P =.007 and P =.017, respectively). Age and sex were not associated with the SLN status. Immunosuppression, increasing tumor diameter, and increasing tumor depth were associated with worse OS (P <.01, P =.003, and P <.025, respectively). DSS differed significantly by group and was best for patients with a negative SLN and worst for those with primary MCC and synchronous clinically evident nodal disease (P =.01).
For patients with MCC, increasing primary tumor diameter and increasing tumor depth are independently predictive of a positive SLN, worse OS, and worse DSS. Tumor depth should be routinely reported when primary MCC specimens are being evaluated histopathologically.

13.  Pregnancy Vaccination with Gold Glyco-Nanoparticles Carrying Listeria monocytogenes Peptides Protects against Listeriosis and Brain- and Cutaneous-Associated Morbidities 
Nanomaterials  2016;6(8):151.
Listeriosis is a fatal infection for fetuses and newborns with two clinical main morbidities in the neonatal period, meningitis and diffused cutaneous lesions. In this study, we vaccinated pregnant females with two gold glyconanoparticles (GNP) loaded with two peptides, listeriolysin peptide 91–99 (LLO91–99) or glyceraldehyde-3-phosphate dehydrogenase 1–22 peptide (GAPDH1–22). Neonates born to vaccinated mothers were free of bacteria and healthy, while non-vaccinated mice presented clear brain affections and cutaneous diminishment of melanocytes. Therefore, these nanoparticle vaccines are effective measures to offer pregnant mothers at high risk of listeriosis interesting therapies that cross the placenta.

14.  Novel nanoparticle vaccines for Listeriosis 
Human Vaccines & Immunotherapeutics  2015;11(10):2501-2503.
In recent years, nanomedicine has transformed many areas of traditional medicine, and enabled fresh insights into the prevention of previously difficult to treat diseases. An example of the transformative power of nanomedicine is a recent nano-vaccine against listeriosis, a serious bacterial infection affecting not only pregnant women and their neonates, but also immune-compromised patients with neoplastic or chronic autoimmune diseases. There is a major unmet need for an effective and safe vaccine against listeriosis, with the challenge that an effective vaccine needs to generate protective T cell immunity, a hitherto difficult to achieve objective. Now utilizing a gold nanoparticle antigen delivery approach together with a novel polysaccharide nanoparticulate adjuvant, an effective T-cell vaccine has been developed that provides robust protection in animal models of listeriosis, raising the hope that one day this nanovaccine technology may protect immune-compromised humans against this serious opportunistic infection.

15.  Treatment with rGDF11 does not improve the dystrophic muscle pathology of mdx mice 
Skeletal Muscle  2016;6:21.
Duchenne muscular dystrophy (DMD) is an inherited lethal muscle wasting disease characterized by cycles of degeneration and regeneration, with no effective therapy. Growth differentiation factor 11 (GDF11), a member of the TGF-β superfamily and myostatin homologous, has been reported to have the capacity to reverse age-related skeletal muscle loss. These initial findings led us to investigate the ability of GDF11 to promote regeneration in the context of muscular dystrophy and determine whether it could be a candidate to slow down or reverse the disease progression in DMD.
Here, we delivered recombinant GDF11 (rGDF11) to dystrophin-deficient mice using the intra-peritoneal route for 30 days and evaluated histology and function in both steady-state and cardiotoxin-injured muscles. Our data confirmed that treatment with rGDF11 resulted in elevated levels of this factor in the circulation. However, this had no effect on muscle contractility nor on muscle histology. Moreover, no difference was found in the number of regenerating myofibers displaying centrally located nuclei. On the other hand, we did observe increased collagen content, which denotes fibrosis, in the muscles of rGDF11-treated dystrophic mice.
Taken together, our findings indicate no beneficial effect of treating dystrophic mice with rGDF11 and raise caution to a potential harmful effect, as shown by the pro-fibrotic outcome.

16.  Sentinel Lymph Node Biopsy Is Indicated for Patients With Thick Clinically Lymph Node-Negative Melanoma 
Cancer  2015;121(10):1628-1636.
Sentinel lymph node biopsy (SLNB) is indicated for the staging of clinically lymph node-negative melanoma of intermediate thickness, but its use is controversial in patients with thick melanoma.
From 2002 to 2012, patients with melanoma measuring ≥4 mm in thickness were evaluated at a single institution. Associations between survival and clinicopathologic characteristics were explored.
Of 571 patients with melanomas measuring ≥4 mm in thickness and no distant metastases, the median age was 66 years and 401 patients (70.2%) were male. The median Breslow thickness was 6.2 mm; the predominant subtype was nodular (45.4%). SLNB was performed in 412 patients (72%) whereas 46 patients (8.1%) presented with clinically lymph node-positive disease and 113 patients (20%) did not undergo SLNB. A positive SLN was found in 161 of 412 patients (39.1%). For SLNB performed at the study institution, 14 patients with a negative SLNB developed disease recurrence in the mapped lymph node basin (false-negative rate, 12.3%). The median disease-specific survival (DSS), overall survival (OS), and recurrence-free survival (RFS) for the entire cohort were 62.1 months, 42.5 months, and 21.2 months, respectively. The DSS and OS for patients with a negative SLNB were 82.4 months and 53.4 months, respectively; 41.2 months and 34.7 months, respectively, for patients with positive SLNB; and 26.8 months and 22 months, respectively, for patients with clinically lymph node-positive disease (P<.0001). The median RFS was 32.4 months for patients who were SLNB negative, 14.3 months for patients who were SLNB positive, and 6.8 months for patients with clinically lymph node-positive disease (P<.0001).
With an acceptably low false-negative rate, patients with thick melanoma and a negative SLNB appear to have significantly prolonged RFS, DSS, and OS compared with those with a positive SLNB. Therefore, SLNB should be considered as indicated for patients with thick, clinically lymph node-negative melanoma.

17.  Exceptional antineoplastic activity of a dendritic-cell-targeted vaccine loaded with a Listeria peptide proposed against metastatic melanoma 
Oncotarget  2016;7(13):16855-16865.
Vaccination with dendritic cells (DCs) is proposed to induce lasting responses against melanoma but its survival benefit in patients needs to be demonstrated. We propose a DC-targeted vaccine loaded with a Listeria peptide with exceptional anti-tumour activity to prevent metastasis of melanoma. Mice vaccinated with vaccines based on DCs loaded with listeriolysin O peptide (91–99) (LLO91–99) showed clear reduction of metastatic B16OVA melanoma size and adhesion, prevention of lung metastasis, enhanced survival, and reversion of immune tolerance. Robust innate and specific immune responses explained the efficiency of DC-LLO91–99 vaccines against B16OVA melanoma. The noTable features of this vaccine related to melanoma reduction were: expansion of immune-dominant LLO91–99-specific CD8 T cells that helped to expand melanoma-specific CD8+ T cells; high numbers of tumour-infiltrating lymphocytes with a cytotoxic phenotype; and a decrease in CD4+CD25high regulatory T cells. This vaccine might be a useful alternative treatment for advanced melanoma, alone or in combination with other therapies.

18.  Biomarker Tools to Design Clinical Vaccines Determined from a Study of Annual Listeriosis Incidence in Northern Spain 
Two regions of northern Spain, Gipuzkoa, and Cantabria present high annual incidence of listeriosis (1.86 and 1.71 cases per 100,000 inhabitants, respectively). We report that the high annual incidences are a consequence of infection with highly virulent Listeria monocytogenes isolates linked to fatal outcomes in elderly patients with cancer. In addition, listeriosis patients with cancer present low IL-17A/IL-6 ratios and significantly reduced levels of anti-GAPDH1–22 antibodies, identified as two novel biomarkers of poor prognosis. Analysis of these biomarkers may aid in reducing the incidence of listeriosis. Moreover, GAPDH1–22-activated monocyte-derived dendritic cells of listeriosis patients with cancer seem useful tools to prepare clinical vaccines as they produce mainly Th1 cytokines.

19.  Long-Term Clinical Responses of Neoadjuvant Dendritic Cell Infusions and Radiation in Soft Tissue Sarcoma 
Sarcoma  2015;2015:614736.
Purpose. Patients with large >5 cm, high-grade resectable soft tissue sarcomas (STS) have the highest risk of distant metastases. Previously we have shown that dendritic cell (DC) based vaccines show consistent immune responses. Methods. This was a Phase I single institution study of neoadjuvant radiation with DC injections on 18 newly diagnosed high-risk STS patients. Neoadjuvant treatment consisted of 50 Gy of external beam radiation (EBRT), given in 25 fractions delivered five days/week, combined with four intratumoral injections of DCs followed by complete resection. The primary endpoint was to establish the immunological response to neoadjuvant therapy and obtain data on its clinical safety and outcomes. Results. There were no unexpected toxicities or serious adverse events. Twelve out of 18 (67%) patients were alive, of which an encouraging 11/18 (61%) were alive with no systemic recurrence over a period of 2–8 years. Favorable immunological responses correlated with clinical responses in some cases. Conclusions. This study provides clinical support to using dendritic cell injections along with radiation in sarcomas, which when used optimally in combination can help clinical outcomes in soft tissue sarcoma. Study registration number is NCT00365872.

21.  A Novel Use of Tisseel in the Setting of Uncontrolled Bleeding in a Thrombocytopenic Patient With Idiopathic Thrombocytopenia 
Urology Case Reports  2015;4:48-50.
We present a case of an 87-year-old female who was evaluated for an 8.5 cm left sided renal mass concerning for malignancy. The patient was transiently thrombocytopenic over the previous 4 months with platelet counts ranging from 50,000 to 125,000 plt/mcL and experienced diffuse hemorrhage during radical nephrectomy with failure to achieve mechanical hemostasis or fulguration. Following Surgicel (Ethicon; Somerville, New Jersey) application, we applied Tisseel (Baxter; Deerfield, IL) to the nephrectomy bed with complete hemostasis of bleeding foci. Tisseel saved this thrombocytopenic patient with uncontrolled bleeding and should have this clinical utility recognized.

22.  Clinical Characteristics and Outcomes for Solitary Fibrous Tumor (SFT): A Single Center Experience 
PLoS ONE  2015;10(10):e0140362.
Solitary fibrous tumor (SFT) is a mesenchymal neoplasm of fibrous origin. The 2013 WHO classification of soft tissue tumors defines malignant forms as hypercellular, mitotically active (>4 mitosis/10 high-power fields), with cytological atypia, tumor necrosis, and/or infiltrative margins. With an IRB-approved protocol, we investigated patient records and clinicopathologic data from our Sarcoma Database to describe the clinical characteristics of both benign and malignant SFT. All pathology specimens were reviewed by two pathologists. Descriptive statistics and univariate/multivariate survival analysis were performed. Patient records and Social Security Death Index were used to evaluate vital status. Of 82 patients, 47 (57%) were women and 73 (89%) were Caucasian. Median age was 62 years (range, 20 to 89). Thirty-two (39%) patients succumbed to the disease. Primary tumor site was lung/pleura in 28 (34%), abdomen/pelvis in 23 (28%), extremity in 13 (16%), and head/neck in 9 (11%) patients. Pathology was described as benign in 42 (51%) and malignant in 40 (49%) patients. Compared to benign SFT, malignant histology is associated with larger tumor size, higher mitotic counts, metastatic disease at diagnosis, and greater use of chemotherapy and radiation therapy. Gender, age, and tumor site were not significantly different between benign and malignant subtypes. By univariate analysis, only benign vs. malignant variant and complete resection positively impacted overall survival (P = 0.02 and P<0.0001, respectively). In the multivariable analysis of overall survival, receiving chemotherapy or not receiving surgery were two variables significantly associated with higher failure rate in overall survival: patients with chemotherapy vs. no chemotherapy (P = 0.003, HR = 4.55, with 95% CI: 1.68–12.34) and patients without surgery vs. with surgery (P = 0.005, HR = 25.49, with 95% CI: 2.62–247.57). Clear survival differences exist between benign and malignant SFT. While surgery appears to be the best treatment option for benign and malignant SFT, better systemic therapies are needed to improve outcomes of patients with metastatic, malignant SFT.

23.  Mutation Scanning in Wheat by Exon Capture and Next-Generation Sequencing 
PLoS ONE  2015;10(9):e0137549.
Targeted Induced Local Lesions in Genomes (TILLING) is a reverse genetics approach to identify novel sequence variation in genomes, with the aims of investigating gene function and/or developing useful alleles for breeding. Despite recent advances in wheat genomics, most current TILLING methods are low to medium in throughput, being based on PCR amplification of the target genes. We performed a pilot-scale evaluation of TILLING in wheat by next-generation sequencing through exon capture. An oligonucleotide-based enrichment array covering ~2 Mbp of wheat coding sequence was used to carry out exon capture and sequencing on three mutagenised lines of wheat containing previously-identified mutations in the TaGA20ox1 homoeologous genes. After testing different mapping algorithms and settings, candidate SNPs were identified by mapping to the IWGSC wheat Chromosome Survey Sequences. Where sequence data for all three homoeologues were found in the reference, mutant calls were unambiguous; however, where the reference lacked one or two of the homoeologues, captured reads from these genes were mis-mapped to other homoeologues, resulting either in dilution of the variant allele frequency or assignment of mutations to the wrong homoeologue. Competitive PCR assays were used to validate the putative SNPs and estimate cut-off levels for SNP filtering. At least 464 high-confidence SNPs were detected across the three mutagenized lines, including the three known alleles in TaGA20ox1, indicating a mutation rate of ~35 SNPs per Mb, similar to that estimated by PCR-based TILLING. This demonstrates the feasibility of using exon capture for genome re-sequencing as a method of mutation detection in polyploid wheat, but accurate mutation calling will require an improved genomic reference with more comprehensive coverage of homoeologues.

24.  Limb Preservation With Isolated Limb Infusion for Locally Advanced Nonmelanoma Cutaneous and Soft-Tissue Malignant Neoplasms 
To demonstrate the efficacy of isolated limb infusion (ILI) in limb preservation for patients with locally advanced soft-tissue sarcomas and nonmelanoma cutaneous malignant neoplasms.
Locally advanced nonmelanoma cutaneous and soft-tissue malignant neoplasms, including soft-tissue sarcomas of the extremities, can pose significant treatment challenges. We report our experience, including responses and limb preservation rates, using ILI in cutaneous and soft-tissue malignant neoplasms.
We identified 22 patients with cutaneous and soft-tissue malignant neoplasms who underwent 26 ILIs with melphalan and actinomycin from January 1, 2004, through December 31, 2009, from 5 institutions. Outcome measures included limb preservation and in-field response rates. Toxicity was measured using the Wieberdink scale and serum creatinine phosphokinase levels.
The median age was 70 years (range, 19-92 years), and 12 patients (55%) were women. Fourteen patients (64%) had sarcomas, 7 (32%) had Merkel cell carcinoma, and 1 (5%) had squamous cell carcinoma. The median length of stay was 5.5 days (interquartile range, 4-8 days). Twenty-five of the 26 ILIs (96%) resulted in Wieberdink grade III or less toxicity, and 1 patient (4%) developed grade IV toxicity. The median serum creatinine phosphokinase level was 127 U/L for upper extremity ILIs and 93 U/L for lower extremity ILIs. Nineteen of 22 patients (86%) underwent successful limb preservation. The 3-month in-field response rate was 79% (21% complete and 58% partial), and the median follow-up was 8.6 months (range, 1-63 months). Five patients underwent resection of disease after an ILI, of whom 80% are disease free at a median of 8.6 months.
Isolated limb infusion provides an attractive alternative therapy for regional disease control and limb preservation in patients with limb-threatening cutaneous and soft-tissue malignant neoplasms. Short-term response rates appear encouraging, yet durability of response is unknown.

25.  Cutaneous Angiosarcoma: A Single-Institution Experience 
Annals of surgical oncology  2013;20(11):3391-3397.
Cutaneous angiosarcoma (CAS) is a rare, aggressive vascular sarcoma with a poor prognosis, historically associated with 5-year overall survival (OS) rates between 10 and 30 %.
This is a single-institution retrospective review of patients treated for CAS from 1999–2011. Demographics, primary tumor characteristics, treatment, and outcomes were analyzed.
A total of 88 patients were identified (median age 70 years and 57 % female). Median tumor size was 3 cm. Median follow-up was 22 months. The 5-year OS and recurrence-free survival (RFS) were 35.2 and 32.3 %, respectively; median was 22.1 months. Also, 36 patients (41 %) received surgery alone, 7 (8 %) received XRT alone, and 41 (47 %) received surgery and XRT. Of the 67 of 88 patients who were disease-free after treatment, 33 (50 %) recurred (median of 12.3 months). Surgery alone had the highest 5-year OS (46.9 %) and RFS (39.9 %) (p = ns). Four presentation groups were identified: (1) XRT induced, n = 30 (34 %), 26 of 30 occurred in females with a prior breast cancer, (2) sporadic CAS on head and neck (H/N), n = 38, (3) sporadic CAS on trunk/extremities, n = 13, and (4) Stewart–Treves n = 7. Those with trunk/extremity CAS had the highest 5-year OS (64.8 %), with H/N CAS having the worst 5-year OS (21.5 %). On MV analysis, only tumor size <5 cm correlated with improved OS (p = 0.014).
In this large series, there appears to be a better overall prognosis than historically reported, especially in Stewart–Treves and CAS on trunk or extremities. While surgery alone was associated with better OS and RFS compared with other treatment modalities, this was not statistically significant. Tumor size was a significant prognostic factor for OS.
