    Abstract Prostate cancer is usually diagnosed when elevated PSA levels lead to a TRUS biopsy. We present a case in which there were several negative biopsies and a rising PSA. This led to a multiparametric MR (mpMRI) which demonstrated a large mass which originated in the anterior transition zone and had extended through the anterior fibromuscular stroma and prostate capsule with a significant extra-prostatic component. The mass was successfully approached anteriorly with a CT-guided biopsy. The patient was subsequently successfully treated with radiotherapy utilizing MR in the planning process. This case report summarizes the utility of mpMRI in this clinical setting. For patients with high suspicion of prostate malignancy despite prior negative biopsies, it can identify tumor in locations not amenable to TRUS biopsy. It also is critical for accurate radiation treatment planning, allowing for increased confidence in tumor targeting as well as sparing sensitive normal tissue.

    Abstract Objective: The research quantitatively evaluates the dosimetric advantage of a helical tomotherapy (HT) intensity-modulated radiation therapy simultaneous integrated boost (SIB) compared to a conventional HT sequential (SEQ) boost for primary intracranial tumors.
    Methods: Hypothetical lesions (planning target volumes or PTVs) were contoured within computed tomography scans from normal controls. A dose of 50 Gy was prescribed to the larger PTV1, while the boost PTV2 received a total of 60 Gy. HT SEQ and HT SIB plans were generated and compared. We evaluated the mean brain dose, the volume of normal brain receiving 45 Gy (V45), the volume of normal brain receiving 5 Gy (V5), and the integral dose. In addition, patients who were treated with the HT SEQ technique were replanned with the HT SIB technique and compared.
    Results: The average reduction in mean brain dose with the HT SIB plan compared to the composite HT SEQ plan was 11·0% [standard error (SE): 0·5]. The reductions in brains V45 and V5 were 43·7% (SE: 2·3) and 3·9% (SE: 0·6), respectively. The reduction in the integral dose was 11·0% (SE: 0·5). When comparing the SIB plan to the first 50 Gy only of the SEQ plan, there was only a 2·5% increase in the mean brain dose and a 2·9% increase in brain V45. This increase was dependent on the relative volumes of PTV2 and PTV1. These results were confirmed for the patient plans compared.
    Conclusions: Treating primary brain tumors with the HT SIB technique provides significant sparing of normal brain parenchyma compared to a conventional HT SEQ boost.

    Abstract In this report the authors review the use of radiotherapy in the treatment of central nervous system (CNS) metastasis. They comment on different treatment methods for both intracranial and extracranial CNS metastasis and discuss some of the evidence supporting the use of radiotherapy in these settings. Recent advancements in radiation oncology technology are briefly reviewed with a focus on the advantages and disadvantages of helical TomoTherapy-based treatment strategies. A review of pertinent current literature was performed. TomoTherapy research currently underway at the University of Virginia Health System is discussed and a representative case is presented. Radiotherapy for CNS metastasis is an effective treatment that provides palliation of symptoms and confers a survival advantage on selected patients. Advances in radiotherapy techniques continue to improve the therapeutic ratio for patients with CNS metastases. Helical TomoTherapy offers distinct advantages for patients with CNS metastatic disease by sparing normal tissue when intracranial or extracranial disease is targeted.

    Abstract Purpose: To evaluate the error in four-dimensional computed tomography (4D-CT) maximal intensity projection (MIP)-based lung tumor internal target volume determination using a simulation method based on dynamic magnetic resonance imaging (dMRI).
    Methods and materials: Eight healthy volunteers and six lung tumor patients underwent a 5-min MRI scan in the sagittal plane to acquire dynamic images of lung motion. A MATLAB program was written to generate re-sorted dMRI using 4D-CT acquisition methods (RedCAM) by segmenting and rebinning the MRI scans. The maximal intensity projection images were generated from RedCAM and dMRI, and the errors in the MIP-based internal target area (ITA) from RedCAM (epsilon), compared with those from dMRI, were determined and correlated with the subjects' respiratory variability (nu).
    Results: Maximal intensity projection-based ITAs from RedCAM were comparatively smaller than those from dMRI in both phantom studies (epsilon = -21.64% +/- 8.23%) and lung tumor patient studies (epsilon = -20.31% +/- 11.36%). The errors in MIP-based ITA from RedCAM correlated linearly (epsilon = -5.13nu - 6.71, r(2) = 0.76) with the subjects' respiratory variability.
    Conclusions: Because of the low temporal resolution and retrospective re-sorting, 4D-CT might not accurately depict the excursion of a moving tumor. Using a 4D-CT MIP image to define the internal target volume might therefore cause underdosing and an increased risk of subsequent treatment failure. Patient-specific respiratory variability might also be a useful predictor of the 4D-CT-induced error in MIP-based internal target volume determination.

    Abstract Background and purpose: Unresectable cholangiocarcinoma is an intractable disease marked by recurrent bouts of biliary obstruction and infection. Traditional treatment methods provide only symptomatic relief and no proven survival advantage. We assessed the tolerability of helical tomotherapy intensity modulated radiotherapy (IMRT) with concurrent capecitabine and photodynamic therapy (PDT) in patients with unresectable hilar cholangiocarcinoma.
    Methods: Ten patients with unresectable hilar cholangiocarcinoma were treated with helical tomotherapy IMRT. An accelerated dose of 50 Gy in 20 fractions (2.5 Gy/fraction) was used. Planning target volume (PTV) consisted of a 1.5 cm radial expansion and a 2 cm craniocaudal expansion of the magnetic resonance imaging and/or contrast enhanced computed tomography-defined gross target volume. PTV ranged from 123 cc to 693 cc (mean 349 cc). Concurrent chronomodulated capecitabine was administered on days of irradiation. Six patients received PDT.
    Results: All patients developed side effects, including grade 2 nausea, and 9 of 10 experienced mild fatigue. Patients lost 3% of their body weight on average. Three patients required brief hospital admission and stent revision for cholangitis during chemoradiotherapy. Capecitabine was discontinued in one patient and decreased in dose for another due to increasing liver enzymes. Median overall survival was 13 months, and median disease-free survival was 10 to 11 months. One patient underwent successful cadaveric liver transplant after chemoradiotherapy and remains disease free 2 years later.
    Conclusions: Concurrent chemoradiotherapy with helical tomotherapy IMRT and capecitabine in conjunction with PDT is well tolerated in patients with hilar cholangiocarcinoma.

    Abstract Purpose: It has been proposed that quantum dots (QDs) can be used to excite conjugated photosensitizers and produce cytotoxic singlet oxygen. To study the potential of using such a conjugate synergistically with radiotherapy to enhance cell killing, we investigated the energy transfer from megavoltage (MV) X-rays to a photosensitizer using QDs as the mediator and quantitated the enhancement in cell killing.
    Methods and materials: The photon emission efficiency of QDs on excitation by 6-MV X-rays was measured using dose rates of 100-600 cGy/min. A QD-Photofrin conjugate was synthesized by formation of an amide bond. The role of Förster resonance energy transfer in the energy transferred to the Photofrin was determined by measuring the degree of quenching at different QD/Photofrin molar ratios. The enhancement of H460 human lung carcinoma cell killing by radiation in the presence of the conjugates was studied using a clonogenic survival assay.
    Results: The number of visible photons generated from QDs excited by 6-MV X-rays was linearly proportional to the radiation dose rate. The Förster resonance energy transfer efficiency approached 100% as the number of Photofrin molecules conjugated to the QDs increased. The combination of the conjugate with radiation resulted in significantly lower H460 cell survival in clonogenic assays compared with radiation alone.
    Conclusion: The novel QD-Photofrin conjugate shows promise as a mediator for enhanced cell killing through a linear and highly efficient energy transfer from X-rays to Photofrin.

    Abstract We report that the actin filament-associated protein AFAP-110 is required to mediate protein kinase Calpha (PKCalpha) activation of the nonreceptor tyrosine kinase c-Src and the subsequent formation of podosomes. Immunofluorescence analysis demonstrated that activation of PKCalpha by phorbol 12-myristate 13-acetate (PMA), or ectopic expression of constitutively activated PKCalpha, directs AFAP-110 to colocalize with and bind to the c-Src SH3 domain, resulting in activation of the tyrosine kinase. Activation of c-Src then directs the formation of podosomes, which contain cortactin, AFAP-110, actin, and c-Src. In a cell line (CaOV3) that has very little or no detectable AFAP-110, PMA treatment was unable to activate c-Src or effect podosome formation. Ectopic expression of AFAP-110 in CaOV3 cells rescued PKCalpha-mediated activation of c-Src and elevated tyrosine phosphorylation levels and subsequent formation of podosomes. Neither expression of activated PKCalpha nor treatment with PMA was able to induce these changes in CAOV3 cells expressing mutant forms of AFAP-110 that are unable to bind to, or colocalize with, c-Src. We hypothesize that one major function of AFAP-110 is to relay signals from PKCalpha that direct the activation of c-Src and the formation of podosomes.

    Abstract Purpose: Stereotactic body radiation therapy (SBRT) has been shown to be an effective, well-tolerated treatment for local control of tumors metastatic to the liver. Multi-institutional Phase II trials are examining 60 Gy in 3 fractions delivered by linac-based, 3D-conformal IMRT. HiArt Helical TomoTherapy is a treatment unit that delivers co-planar helical IMRT that is capable of image-guided SBRT. We hypothesized that the maximum tolerable dose (MTD) delivered to a lesion by Helical TomoTherapy-based SBRT could be predicted based on the planning target volume (PTV) and liver volume.
    Methods and materials: To test this, we performed inverse treatment planning and analyzed the dosimetry for multiple hypothetical liver gross tumor volumes (GTV) with conventional PTV expansions. Inverse planning was carried out to find the maximum tolerated SBRT dose up to 60 Gy to be delivered in 3 fractions based on the dose constraint that 700 cc of normal liver would receive less than 15 Gy.
    Results: Regression analysis indicated a linear relationship between the MTD, the PTV and the liver volume, supporting our hypothesis. A predictive equation was generated, which was found to have an accuracy of +/-3 Gy. In addition, dose constraints based on proximity to other normal tissues were tested. Inverse planning for PTVs located at varying distances from the heart, small bowel, and spinal cord revealed a predictable decrease in the MTD as the PTV increased in size or approached normal organs.
    Conclusions: These data provide a framework for predicting the likely MTD for patients considered for Helical TomoTherapy liver SBRT.

    Abstract Background: Compression fractures are common in patients with osteoporosis and cancer. In particular, vertebral compression fractures are crippling, and pose an additional risk of cord compression. Although a number of nonmedical options such as bracing and exercise programs may help these patients, the combination of constant, severe pain and spinal instability was until recently almost invariably synonymous with painful gradual deterioration and a poor quality of life. Vertebroplasty, and more recently kyphoplasty, are minimally invasive procedures that aim at limiting or reversing painful collapse of the vertebrae, while providing stability to the treated segment of the spine. As these new options are highly effective and involve minimal risk, it is important that physicians be familiar with them.
    Objective: This paper reviews the demographics of vertebral compression fractures, both osteoporotic and neoplastic, the technical aspects of vertebroplasty and kyphoplasty, and current results and outcomes.
    Results: Pain relief rates in excess of 90% have been reported with both vertebroplasty and kyphoplasty in patients with vertebral compression fractures. Procedural complication rates should be very low, in the 1%-2% range at most with proper technique.
    Conclusions: Until the advent of vertebroplasty, almost no effective therapeutic option could be offered to patients suffering from neoplastic or osteoporotic vertebral compression fractures, which are relatively common and often crippling. The technical feasibility of these procedures is high, the risk low, and the effectiveness high. Therefore, it is important that physicians consider vertebroplasty and kyphoplasty as viable and strong options.
