Abstract
Objectives Long bone defects often require surgical intervention for functional restoration. The ‘gold standard’ treatment is autologous bone graft (ABG), usually from the patient’s iliac crest. However, autograft is plagued by complications including limited supply, donor site morbidity, and the need for an additional surgery. Thus, alternative therapies are being actively investigated. Autologous bone marrow (BM) is considered as a candidate due to the presence of both endogenous reparative cells and growth factors. We aimed to compare the therapeutic potentials of autologous bone marrow aspirate (BMA) and ABG, which has not previously been done. Methods We compared the efficacy of coagulated autologous BMA and ABG for the repair of ulnar defects in New Zealand White rabbits. Segmental defects (14 mm) were filled with autologous clotted BM or morcellized autograft, and healing was assessed four and 12 weeks postoperatively. Harvested ulnas were subjected to radiological, micro-CT, histological, and mechanical analyses. Results Comparable results were obtained with autologous BMA clot and ABG, except for the quantification of new bone by micro-CT. Significantly more bone was found in the ABG-treated ulnar defects than in those treated with autologous BMA clot. This is possibly due to the remnants of necrotic autograft fragments that persisted within the healing defects at week 12 post-surgery. Conclusion As similar treatment outcomes were achieved by the two strategies, the preferred treatment would be one that is associated with a lower risk of complications. Hence, these results demonstrate that coagulated BMA can be considered as an alternative autogenous therapy for long bone healing. Cite this article: Z. X. H. Lim, B. Rai, T. C. Tan, A. K.

Abstract
PURPOSE This study aimed to calculate the expansion margins around enlarged pelvic lymph nodes to encompass internal motion and setup errors during intensity modulated radiation therapy with simultaneous integrated boost for cervical cancer. METHODS AND MATERIALS Four-dimensional computed tomography scans were obtained for 19 patients with cervical cancer, and 32 fluorodeoxyglucose-avid pelvic lymph nodes were delineated in different respiratory phases to calculate respiratory displacement. Setup variations during daily treatments were estimated from on-board imaging. Descriptive statistics were used to quantify the expansion margins using Mc Kenzie and Van Herk formulas separately. An analysis of variance was used to analyze the volumetric impact of the margins. RESULTS Based on the McKenzie formula, an internal margin (internal target volume) of 3 mm and setup margin (planning target volume) of 5 mm was required to adequately encompass respiratory and setup uncertainties, respectively. Although the use of the Van Herk formula necessitated a single 6 mm expansion margin for all uncertainties, which resulted in a significant reduction in boost volume, inherent limitations in our methodology might pose a higher risk of target miss with such smaller margins. CONCLUSIONS An isotropic expansion margin of 3 mm for the internal target volume and 5 mm for the planning target volume is necessary for enlarged pelvic lymph nodes while planning intensity modulated radiation therapy with simultaneous integrated boost for cervical cancer.

Abstract
Context Vulvar cancer is one of the uncommon gynecological malignancies. Multimodality treatment with surgery, radiotherapy, and chemotherapy are required for treatment of the disease. Aims The aim of the study was to evaluate clinical outcome in patients of carcinoma vulva, treated at our institution. Subjects and Methods This was a retrospective-cohort study done in 50 patients with squamous cell carcinoma of the vulva, treated at our institution from January 2008 to December 2014. Data were analyzed on the basis of age, stage, type of treatment received, and treatment-related toxicity. Disease-free survival and overall survival were estimated. Statistical Analysis Used Kaplan-Meier survival analysis and Chi-square test were used for statistical analysis. Results Majority of the patients (52%) had presented with Stage III disease. Thirty-six of 50 patients underwent surgery: simple vulvectomy - 2, radical vulvectomy - 34, bilateral inguinal lymph node dissection was done in 32 patients, and 1 patient underwent ipsilateral-inguinal lymph node dissection. Among 40 patients who received radiotherapy and eight patients received palliative radiotherapy. Seventeen patients underwent intensity-modulated radiotherapy (IMRT) and 15 patients received conventional radiotherapy. Significantly less Grade 2 or more skin toxicity (P = 0.003) observed in patients who underwent IMRT. Among non-IMRT group, eight patients required treatment break during radiation. At a median follow-up time of 25.5 months, median overall survival was 31 months and median disease-free survival was 25 months. About 42% patients were alive and free of disease at last follow-up. Conclusions Modified radical vulvectomy with inguinal lymph node dissection followed by radiotherapy is the mainstay of management of locally advanced carcinoma vulva. Using IMRT, we could minimize the treatment related radiation toxicity and treatment breaks.

Abstract
Objective(s) This study aimed to retrospectively evaluate the toxicity and clinical outcomes in patients of locally advanced cervical cancer treated with three-dimensional conformal radiotherapy (3DCRT) and concurrent chemotherapy. Material and methods Two hundred and ten newly diagnosed patients of locally advanced cervical cancer of FIGO 2009 Stage II-III treated with 3DCRT (46 Gy/23 fractions/4½ weeks) and weekly concurrent Cisplatin (40 mg/m2), from January 2013 to 2015 were analyzed. A planning computed tomography was performed and contouring was done according to published guidelines. External radiotherapy was followed by Intracavitary brachytherapy delivered to a dose of 9 Gy HDR in 2-fractions, given one week apart. The endpoints were treatment related toxicities and clinical outcomes. Local control (LC), overall survival (OS) and disease free survival (DFS) were evaluated and toxicities were documented using the common terminology criteria for adverse events (v3.0) (CTCAE). Results The median follow up time was 37 (range, 19-54) months. The 3 year OS, DFS and LC were 84.2%, 80.6% and 81% respectively. Grade ≥3 acute skin, upper and lower gastrointestinal (GI) and genitourinary (GU) toxicity was observed in 3 (1.4%), 11 (5.2%), 12 (5.7%) and 0 (0%) patients, respectively. Grade ≤2 hematological toxicity was observed in 154 (73.3%) patients. Grade ≥3 late GI and GU toxicity was seen in 9 (4.2%) patients and 2 (0.9%) patients, respectively. Conclusion 3DCRT with concurrent chemotherapy results in good loco-regional control with acceptable normal tissue toxicity. In the background of indeterminate evidence regarding routine practice of intensity modulated radiotherapy in carcinoma of the cervix, 3DCRT may be considered as the treatment of choice.

Abstract
BACKGROUND The oral health status of pregnant women in low-resource communities such as Nepal has not been well characterized. This sub-population is also of specific interest given associations between poor oral health and adverse pregnancy outcomes previously documented in other settings. We explored relationships between gingivitis and risk factors among pregnant women in rural Nepal. METHODS The design was a community-based, cross-sectional study in a sub-area of Sarlahi District, Nepal. Pregnant women < 26 weeks gestation underwent clinical periodontal exams conducted by community-based oral health workers. Exams included a full mouth assessment measuring bleeding on probing (BOP), probing depth (PD) (six sites per tooth), and gingival recession, the distance from the cemento-enamel junction to the free gingival margin (two direct sites per tooth). Data on participant risk factors were collected through household surveys, including demographic characteristics, oral health behaviors, care seeking, and health attitudes. Multivariable logistic regression modeling was used to assess relationships between gingivitis and risk factors. RESULTS We enrolled 1452 participants, of which 40% (n = 582) had signs of clinical gingivitis and 60% (n = 870) clinical health. Average participant age was 23. Most participants (88%) had never received oral health care. Participants averaged 10% of sites with BOP with most (79%) having ≥1 site with BOP. Nine percent of participants had ≥1 site with PD ≥4 mm, although very few participants (0.7%) had sites with PD ≥5 mm. Few participants (13%) had any recession (≥1 mm). In the final adjusted model, odds of gingivitis increased by 3% for each year of age (aOR 1.03, 95% CI 1.00, 1.06) and were higher for women of short maternal stature (< 150 cm) (aOR 1.43, 95% CI: 1.14, 1.79) and among women reporting cost to be a barrier to seeking dental care (aOR 2.13, 95% CI: 1.09, 4.15). CONCLUSIONS Gingivitis was common and associated with age, maternal stature, self-reported high cost of dental care, and other risk factors among pregnant women in rural Nepal. TRIAL REGISTRATION ClinicalTrials.gov Identifier: NCT01177111 (Nepal Oil Massage Study) and NCT02788786 (Pilot Trial).

Abstract
BACKGROUND The phenomenon of vanishing carcinomas, first described in context of prostatic carcinomas, has been documented in endometrial carcinomas as well. METHODS The archives of the department were searched for case files of endometrial carcinoma diagnosed on endometrial curetting/biopsy but which did not reveal any cancer on the subsequent hysterectomy specimen. Clinical and pathological correlation was established. RESULTS A total of 5 cases were retrieved with biopsy-diagnosed endometrial carcinomas, 4 endometrioid and 1 serous type, which on subsequent hysterectomies did not reveal any tumor. These 5 cases represented 1.56% of total hysterectomies in our series. All were Stage Ia tumors, which on follow-up (mean = 18.2 months) did not show any local reoccurrence. Adjuvant therapy was instituted in 1 case in the form of pelvic irradiation in view of the serous histology. In all cases, the primary diagnosis was reconfirmed and any remote possibility of incorrect patient identification, laboratory errors, and institution of hormonal therapy were adequately ruled out along with an extensive endometrial sampling in hysterectomy. CONCLUSION The recognition of "vanishing endometrial carcinoma" as a distinct entity is of utmost importance to avoid mislabeling them as medical errors.

Abstract
The publication of the GEC-ESTRO recommendations one decade ago was a significant step forward for reaching international consensus on adaptive target definition and dose reporting in image guided adaptive brachytherapy (IGABT) in locally advanced cervical cancer. Since then, IGABT has been spreading, particularly in Europe, North America and Asia, and the guidelines have proved their broad acceptance and applicability in clinical practice. However, a unified approach to volume contouring and reporting does not imply a unified administration of treatment, and currently both external beam radiotherapy (EBRT) and IGABT are delivered using a large variety of techniques and prescription/fractionation schedules. With IGABT, local control is excellent in limited and well-responding tumours. The major challenges are currently loco-regional control in advanced tumours, treatment-related morbidity, and distant metastatic disease. Emerging evidence from the RetroEMBRACE and EMBRACE I studies has demonstrated that clinical outcome is related to dose prescription and technique. The next logical step is to demonstrate excellent clinical outcome with the most advanced EBRT and brachytherapy techniques based on an evidence-based prospective dose and volume prescription protocol. The EMBRACE II study is an interventional and observational multicentre study which aims to benchmark a high level of local, nodal and systemic control while limiting morbidity, using state of the art treatment including an advanced target volume selection and contouring protocol for EBRT and brachytherapy, a multi-parametric brachytherapy dose prescription protocol (clinical validation of dose constraints), and use of advanced EBRT (IMRT and IGRT) and brachytherapy (IC/IS) techniques (clinical validation). The study also incorporates translational research including imaging and tissue biomarkers.

Abstract
Complete Annular pancreas (AP) is a rare congenital anomaly, often presented and operated at the early age of life. Adult presentation group usually presents with either biliary or duodenal or pancreatic symptoms. We report a case of 43 years old female presenting with concurrent enteric, biliary and pancreatic symptoms admitted on April 2016 in Hepatobiliary and Pancreatic Surgery Department of BSMMU, Dhaka, Bangladesh. A complete type of annular pancreas with partial duodenal stenosis and dilated common bile duct was observed during laparotomy. We performed gastrojejunostomy as well as hepaticojejunostomy (Roux-en-Y anastomosis). Patient was discharged in a good symptom free condition. Complete Annular Pancreas can present at any age, with any one or all of the biliary, pancreatic or duodenal symptoms. Surgery is the treatment of choice and has a good outcome.

Abstract
Introduction: Three-dimensional (3D) treatment planning of patient undergoing radiotherapy uses complex and meticulous computational algorithms. These algorithms use 3D voxel data of the patient to calculate the radiation dose distribution and display it over the CT image dataset for treatment plan evaluation. Aims and Objective: The purpose of the present study is the development and implementation of radiobiological evaluation of the radiotherapy treatment plan incorporating the tissue-specific radiobiological parameters. Material and Method: An indigenous program was written in MATLAB® software (version 2011b of Mathworks Inc.) to extract the patient treatment plan data from DICOM-RT files which are exported from the treatment planning system. CT-, Structures- and Dose-Cube matrices are reconstructed from the exported patient plan data. BED and EQD2 based dose volume histograms (DVHs), colorwash and iso-effective dose curves were generated from the physical Dose-Cube using the linear-quadratic (LQ) formalism and tissue-specific radiobiological parameters (α/β). Results and Conclusion: BED-and EQD2-colorwash and iso-effective curves along with BED and EQD2 dose volume histograms provide superior radiobiological information as compared to those of physical doses. This study provides supplementary recipes of radiobiological doses along with the physical doses which are useful for the evaluation of complex radiotherapy treatment plan of the patients.

Abstract
PURPOSE To evaluate the long-term disease control and toxicity to the organs at risk after dose-escalated image-based adaptive brachytherapy (BT) in cervical cancer. METHODS AND MATERIALS Sixty patients of cervical cancer were treated with external radiotherapy 46 Gy in 23 fractions with weekly cisplatin and MRI-guided BT 7 Gy × 4 fractions with a minimum dose of 85.7 Gy (EQD2) to the high-risk clinical target volume (HRCTV). The BT dose was initially prescribed to point A and plans were optimized to ensure coverage of both point A and HRCTV while maintaining doses to the organs at risk within the recommended constraints. Patients were followed up clinically every three months for the first two years and six months thereafter. Toxicity scoring for urinary and bowel symptoms was done using CTCAE version 3.0. RESULTS The mean doses to the point A and D90 HRCTV were 85.5 (±2.75) Gy and 98.4 (±9.6) Gy EQD2 respectively. The mean 2 cc EQD2, the bladder, rectum, and sigmoid were 90.6 Gy, 70.2 Gy, and 74.2 Gy respectively. The overall survival at a median followup of 49.8 months was 91.66%. Six (10%) patients developed grade 3 gastrointestinal toxicity. One patient developed grade 3 bladder toxicity. The incidence of bladder, rectal, and sigmoid toxicity increased significantly with doses >85 Gy, 66 Gy, and >71 Gy EQD2 respectively. CONCLUSIONS While the incidence of grade 3-4 toxicity was low (8.3% for gastrointestinal toxicity and 1.6% for bladder), the threshold for development of grade 1-2 bladder and rectal toxicity was lower than the doses recommended by the GEC-ESTRO group. By adhering to volume-based prescriptions, there is scope of further reduction in toxicity to organs at risk.

Abstract
OBJECTIVE Lymphomas are diverse group of neoplasm affecting the lymphoreticular system. Diffuse large B cell lymphoma is the most frequently diagnosed type of non-Hodgkin lymphoma and is the fifth most frequent malignancy, accounting for about 40% of cases reported. In the present case report a 40 year old female patient complains of swelling on right side of face since 45 days and gradually increased to present size. Intra-orally an ulcero-proliferative growth was present on the right side of hard palate. Incisional biopsy was suggestive of Lymphoproliferative disorder. Panel of immunohistochemical antibodies were used; which showed positivity for CD45, PAX5, Bcl2, Ki67, CD138 and negativity for CD3, CD10, CD20 and CD30. Therefore through routine standard hematoxylin and eosin staining a clear cut diagnosis of specific lymphoma was difficult to obtain and thus immunohistochemistry plays an important role in confirming the pinpoint diagnosis.
