In this paper is presented our longstanding experience with combination of teleradiotherapy and superficial hyperthermia in the treatment of patients with head and neck cancers, especially in cases with superficial tumors or lymph node metastases, in the Institute of Radiation Oncology in Prague. Microwave thermotherapy - hyperthermia in combination with other treatment methods (mainly with teleradiotherapy) is currently very effective and important method for cancer treatment. Technical equipment for before- mentioned therapeutic method in this clinical working place is described as well. The treatment results were evaluated after 1-2 month after end of treatment series by various examination methods. They are part of this paper as well.
Objective: Discussing the ultrasonic and pathologic features of Diffuse Sclerosing Variant of Papillary Thyroid Carcinoma (DSVPTC) in order to raise awareness of this disease. Methods:To collect ultrasonic and pathologic features of 47 cases of DSVPTC which confirmed pathologically referred to Department of Thyroid Surgery, the First Hospital of Jilin University from 2008 to 2015. Results:(1) Diffuse hyperechoic, coarse, heterogeneous echogenicity were visualized on ultrasonography in 43 patients. Scattered microcalcifications were found in the thyroid tissue without definite local lesions. Normal thyroid tissue was not seen on ultrasonography. 4 patient only has unilateral and the isthmus changes above. (2) On color doppler sonography, abundant blood supply was visualized in the thyroids in all patients. (3)43 patients had bilateral cervical lymph node metastases with microcalcification, and 4 patient had ipsilateral cervical lymph node metastases. (4)43 patients (including 1 patient with liver and lung metastasis) underwent bilateral total thyroidectomy and bilateral neck lymph node dissection, while 4 patient underwent bilateral total thyroidectomy and unilateral neck lymph node dissection. All were treated postoperatively by radioiodine and endocrine suppression. Conclusions: The ultrasonic features of diffuse thyroid carcinoma are characteristic. Ultrasonography plays an important role in the diagnosis of diffuse thyroid carcinoma. To prolong patients's survival time, diffuse thyroid carcinoma should be treated surgically as soon as possible, assisting I<sup>131</sup> and endocrine suppression therapy after surgery.
A handheld THz probe has been developed by TeraView with the goal to assess tumor resection margins intra-operatively in breast-conserving surgery (BCS) specimens and metastatic status of sentinel lymph nodes (SLNs), with a view to reduce re-operation rates. The utility of this probe for this purpose has already been shown in an ex vivo setting. Further work carried out by Teraview Ltd together with the breast surgical team at King's College London (KCL)/Guy's and St Thomas's NHS Foundation Trust (GSTT) is confirming promise of this technique, with focus on the in vivo application of the handheld THz probe for real-time assessment of tumor resection margins in BCS. In particualr, the probe is designed to acquire THz images during breast cancer surgery to distinguish between normal and malignant breast tissue, thus assisting complete surgical excision of cancers. Findings of this study leading to in-vivo testing are discussed in this paper.
In this paper, we present a graph-based multi-resolution approach for mitosis extraction in breast cancer histological whole slide images. The proposed segmentation uses a multi-resolution approach which reproduces the slide examination done by a pathologist. Each resolution level is analyzed with a focus of attention resulting from a coarser resolution level analysis. At each resolution level, a spatial refinement by semi-supervised clustering is performed to obtain more accurate segmentation around edges. The proposed segmentation is fully unsupervised by using domain specific knowledge.
We developed an animal model for chronic observation with using two-photon microscopy. To demonstrate potency of the model, T-cell migration and proliferation in inguinal lymph node were observed for two weeks on single mice. The image quality was maintained enough high during a observation period to count and trace cell population and migration.
A significant problem affecting the stability of hips and knees in the total joint arthroplasty is the aseptic loosening of the implants due to the osteolysis by the ultra molecular weight polyethylene (UHMWPE) wear particles. Recently, Oil Red O (ORO) stain was used in identifying these particles in the tissues retrieved from the failed implants. The objective of the authors' study was to examine the effect of two micron polyethylene particles (4 mg) implanted into the rabbit knees for periods of 6 and 9 months. The authors examined the sections of liver, kidneys, popliteal lymph nodes, femurs and tibias to detect the presence of UHMWPE particles. Soft tissue or bones were first embedded in paraffin blocks and five micron sections were cut. One section was stained with Hematoxylin and Eosin (H&E) stain and the other with ORO stain. The slides were viewed under a polarized light using a light microscope. The results showed the presence of the polyethylene particles in the soft tissues such as liver, kidneys and popliteal lymph nodes as well as in the tibia and femurs. They demonstrated that these polyethylene particles are easily seen either with H&E or ORO stain. They were either round or needle shaped. A visible comparison of tissue sections appeared to indicate the presence of greater number of particles in the specimens from the 9 month animal than those seen in the 6 month animals.
In this paper, an automatic cancer detection method that combines multiple features to support pathologists was proposed. Cancer is the most cause of death in Japan, and patients suffering with cancer are increasing every year, while the number of pathologists is almost constant. Such issues increase the burden on the pathologists and causes service degradation for the patients. The proposed method combined three image features, Higher-order Local Auto- Correlation (HLAC) feature, Wavelet feature, Delaunay feature. At first, the features were calculated from gastric lymph node images. Then we connected each feature into each vector of varying combinations of the features, and discriminated cancer and no cancer by Support Vector Machine (SVM). HLAC, Wavelet and Delaunay features are shape, frequency, and cell-position geometrical one respectively. Cancer detection rates with more than two features combination were better than only one. In the best performance, sensitivity and specificity were 94.6% and 84.9% respectively.
Quantitative high-frequency ultrasound (QHFU) imaging methods are under investigation to evaluate their ability to detect small nodal metastases in lymph nodes freshly dissected from cancer patients. To apply these methods, a critical preprocessing step is 3D segmentation of the lymph-node ultrasound echo-signal dataset. Segmenting the residual fat layer and the lymph node is critical in order to avoid bias in the QHFU estimates (e.g., scatterer size and acoustic concentration) due to attenuation and to exclude estimates obtained from the fat regions. Segmentation also provides absolute measurements of lymph-node dimensions that are necessary to match 3D ultrasound with 3D histology. In this study, a 3D region-based segmentation algorithm was developed and compared quantitatively using Dice's mutual- overlap criterion with 2D manual segmentation of 9 representative cross sections. The method was tested on 13 lymph nodes, and resulting Dice scores had mean values of 0.81 and 0.78 for lymph node and fat segmentation, respectively.
Since biological tissues have about 70 or 80% water, the water structure in tissue may be attributed to tissue water. The relaxation time using NMR in cancerous tissue was investigated in various experimental tumors. It was established that for solid tumors in MH134-C<inf>3</inf>H/He and leukemic mice, the relaxation time (T<inf>1</inf>and T<inf>2</inf>) measured by NMR was higher than that of other tissues except brain and lymph node. Moreover, in induced hepatoma and regenerating liver, the value of T<inf>2</inf>increases in accordance with the malignancy of tumor growth. In another experiment, it was found that protoporphyrin, which has anticancer action without destroying cancer cells at least in vitro, inhibits the increase of T<inf>1</inf>and T<inf>2</inf>in solid tumors (MH134-C<inf>3</inf>H/He) when administered intra-tumor every day. The increase of relaxation time using NMR is considered not only as the increase of motional freedom, but also as the decrease of ordering of tissue water, which has a close connection with disdifferentiation of tissue. Although the clinical application of relaxation time using NMR for differential diagnosis of cancer requires further study, these experimental results suggest that the prolongation of relaxation time may indicate the malignancy of neoplastic growth.
