Majority of data regarding the same pertains to the treatment of the conserved breast. This study aimed to compare the use of standard wedge-based tangentials (two-dimensional [2D] TW) versus 3D conformal radiotherapy field in the field (3DCRT FIF) with the intent of evaluating if the latter would provide a dosimetric advantage.Materials and Methods: Twenty-six postmastectomy patients were enrolled in this study. Comparative plans using 2D TW and 3DCRT FIF were generated to deliver 50 Gy in 25 fractions. Dosimetric parameters pertaining target dose, Homogeneity Index (HI), Conformity Index , and dose to normal structures were compared and analyzed. The parameters that achieved significance were evaluated using the hypofractionated plan.Results: The 3DCRT FIF plan showed better planning target volume coverage, V95%(P < 0.001) and less cardiac dose (V30and MD) as well as lung V20,V30,MD, and V5for both lungs (P < 0.001). The dose to the left descending coronary artery (LAD) was also less with a trend toward significance (P = 0.07). The 3DCRT FIF plan also improved HI (P = 0.02). However, the high-dose volume V107%and radiation exposure were not higher. The significant parameters were evaluated in the hypofractionated schedule of 40 Gy/15 Fr. The MD to the heart was 8.96 Gy in FIF plan versus 20.16 Gy in TW plan. The average V20to the ipsilateral lung was 37.8% versus 65.2%. The average dose to the contralateral breast was 50% less, i.e., 3.92 Gy versus 8.96 Gy.Conclusion: The results of this study suggest that there would be a significant benefit of using 3DCRT FIF plans for patients being considered for hypofractionated radiotherapy in the postmastectomy setup.

T Krishna Mohan, Bogala Shilpa, Veeraiah K Chaudhary Asian Journal of Oncology 2017 3(2):106-110 Aims and Objectives: Aim of this study was to assess the clinical usefulness of Acoustic Radiation Force Impulse (ARFI) elastography imaging in differentiating benign and malignant/metastatic superficial nodes. Methods and Materials: ARFI elastography (Siemens Medical Solutions, Mountain View, CA) using Virtual touch Tissue Imaging (VTI) technique was performed and Shear wave velocity (m/sec) was measured in 85 patients (mean age, 49 years; range, 16–72 years) with 126 lymph nodes (96 axillary, 21 cervical and 9 inguinal nodes) which were biopsied and histo-pathologically correlated. Results: Of 126 nodes, 71 were benign (64 reactive and 7 koch's) and 55 were malignant (40 metastases and 15 lymphoma). The mean ARFI value of malignant nodes ±SD (4.42 ± 2.60) were significantly higher than the benign nodes (1.76 ± 0.44), with P <0.001. With the use of Receiver Operating Characteristic (ROC) curve, the cut off SWV was estimated to be 2.45m/s with sensitivity of 83.6%, specificity of 91%, and accuracy of 93.7 % while the conventional US based short axis diameter (SAD) measurement with cut off value of 10mm, showed the sensitivity of 62 %, specificity of 87% and accuracy of 87%. Conclusion: Acoustic radiation force impulse elastography is feasible for superficial lymph nodes and provides quantitative elasticity measurements, which may complement B-mode ultrasound and potentially improve the differentiation of benign and malignant/metastatic lymph nodes.

Sidoun, Yasin Topov, Mohamed A Elfageh, Noura A Mansour, Abdullah A Jwaid, Alhadi M Jahan, Mussa A Alragig Asian Journal of Oncology 2017 3(2):111-115 Background: Lung biopsies may be classified according to the method of access or by the reason for biopsy. Tru-cut biopsy is a simple, relatively safe, rapid, and reliable technique for the diagnosis of lung mass lesions, particularly with the aid of computed tomography (CT) scan. This procedure is commonly used worldwide to detect different kinds of lung tumors, but its usefulness in Libya is not yet studied.Objectives: The aim of this study was to assess the usefulness of Tru-cut biopsy as a diagnostic method in lung tumors and also to determine the incidence of lung cancer in various ages and sex groups and in relation to smoking data.Patients and Methods: Retrospective study was done on 136 patients who underwent CT-guided Tru-cut biopsy from January 2012 to March 2015. The included patients have lung mass lesions suspected to be neoplastic according to chest radiograph and/or CT scan.Results: We found biopsies and histopathology reports of 136 cases. The patients' age was from 20 to 85 years with the peak incidence in the sixth and seventh decades. The benign lesions were 18 (13.23%), and malignant lesions were 118 (86.76%) documented microscopically. The most common tumor was squamous cell carcinoma (25.17%), followed by adenocarcinoma (23.02%) and small cell lung carcinoma (17.26%). Nonspecific inflammation was found in 8.63%.Conclusion: CT-guided Tru-cut biopsy is a simple, safe, and reliable procedure with high diagnostic accuracy for the diagnosis and subtyping of lung cancer. The definitive result of malignancy is a base for correct decision for the patient's treatment after careful clinical correlation with performance state, radiology findings, and complete serological investigations.

Amongst the inflammatory cells, Tumor Associated Macrophages (TAMs) play a key role in the tumorigenesis. This study elucidates the density of TAMs in invasive mammary carcinomas and attempts to establish aa association with the following pathological variables: tumor size, histological grade, nodal status, hormonal expression status and Her2Neu overexpression. Materials and Methods: 90 diagnosed archival cases of invasive mammary carcinomas at a tertiary care centre were included. Density of TAMs was assessed by using CD68 which is a pan-macrophage marker by immunohistochemistry on the archival tissue blocks. The density TAMs (CD68 positive cells) was dichotomised into high (>50 CD68 positive cells/ HPF) and low (<5050 CD68 positive cells/ HPF) and compared with the above mentioned pathological variables using appropriate statistical tests. Results: The density of TAMs was significantly higher around the infiltrating edge of the carcinoma in comparison to the adjoining normal terminal duct lobular units. The density of TAMs was more in the infiltrating edge of the tumor than within the tumor nodule/nests. A higher TAM density showed a significant association in tumors having large tumor size, higher histological grade, nodal metastasis, absence of ER and PR expression and Her2Neu overexpression (p value <0.05). Conclusion: TAMs play an important role in tumor progression in invasive mammary carcinomas. This is as a result of the multiple roles enacted by TAMs in the various stages of tumor development starting from tumor growth, invasion, angiogenesis and metastases. Targeted therapy against TAMs has great potential in the being important components of future treatment strategies against breast carcinomas.

The management of these patients consists of supportive care and disease-directed treatment. Combined modality treatment (surgical resection or radiosurgery, followed by whole brain radiotherapy) of brain metastases has greatly improved the local control of disease in patients with single lesion, good functional performance status, and controlled extracranial disease as demonstrated in prospective randomized studies. For patients with multiple brain metastases, conventional fractionated whole brain radiotherapy continues to be a standard and efficacious treatment. At present, experience with the use of molecularly targeted tyrosine kinase inhibitors in nonsmall cell lung cancer patients with activating mutations in the epidermal growth factor receptor gene and anaplastic lymphoma kinase gene is growing. However, their effectiveness in patients with brain metastases is not well established. In the arena of targeted therapies, vascular endothelial growth factor pathway inhibitors such as bevacizumab have shown some activity in brain metastases. Further prospective studies are necessary to facilitate selection of patient subpopulation for targeted agents in future studies.

Sparing of the normal structures has been made more achievable than ever before by use of technologies such as Intensity Modulated Radiotherapy (IMRT) and Image guided radiotherapy (IGRT). However, unlike, sites such as brain or head neck, thorax is a site in active motion, mostly contributed by patient's respiratory movement. 4 D radiotherapy, that addresses the issues of motion in thoracic tumours answers this critical question. The present article outlines the scope of need for 4 D radiotherapy and discusses the options available for 4 D treatments of cancer patients.

Khandeparkar, Avinash R Joshi Asian Journal of Oncology 2017 3(2):139-143 Mammary analog secretory carcinoma (MASC) is a low-grade malignant tumor of salivary glands. It is so named because of its cytohistopahological, immunohistological, and cytogenetic resemblance to secretory carcinoma of the breast. Since the first description of this tumor in 2010, about 70 cases have been reported in literature. We report a case of this recently described tumor in a 21-year-old female. The radiological diagnosis of her parotid swelling was pleomorphic adenoma. The cytological evaluation was suggestive of oncocytoma. The histopathology showed a low-grade malignant neoplasm and the differential included papillary variant of acinic cell carcinoma, oncocytic variant of mucoepidermoid carcinoma, and MASC. Immunohistochemistry confirmed the diagnosis of MASC. We have included a brief review of literature.

A case of carcinoma cervix in a 56-year-old female is described who presented with full chamber pseudohypopyon and deep vascularization in inferior quadrant of the cornea in the left eye. Magnetic resonance imaging revealed features suggestive of ocular metastasis in the anterior part of the uveal tract. Diagnosis was confirmed on cytology which showed features of squamous cell carcinoma. A high level of clinical suspicion in advanced cases of malignancies will help in early detection of ocular metastasis with unusual presentations.
