Abstract
Pathologies of the vagina are important causes of symptoms related to the genital tract in women. They can be missed on transabdominal ultrasonography (USG), which is the baseline modality used for evaluation of gynaecological complaints. Transperineal USG and MRI are the imaging modalities of choice for evaluation of the vagina. Diseases of the vagina can be grouped depending upon the age group in which they occur. In children and young adults, congenital anomalies like longitudinal or transverse vaginal septum, imperforate hymen, vaginal aplasia or atresia, and rectovaginal fistula can be seen. Malignant tumours can rarely occur in children, rhabdomyosarcoma being the most common one. Common diseases affecting adults include benign lesions like epidermoid, Gartner duct, and Bartholin cysts, and urogenital fistulas involving the vagina. Endometriosis and other benign tumours of vagina including leiomyoma, fibroepithelial polyp, and angiomyxoma are occasionally seen. Malignant tumours can be primary, the most common one being squamous cell carcinoma, or secondary, due to direct extension from cancers involving the adjacent organs. Characteristic morphological changes occur in the vagina after radiotherapy, which can be identified on imaging. Knowledge about the imaging appearances of these diseases is crucial in guiding appropriate management.

Abstract
While breast carcinoma is the most feared pathology in women with breast lumps, infections continue to be an important aetiology, especially in countries with low to middle socio-economic status. The breast infections or mastitis can present as acute painful breast or recurrent episodes of breast lumps with or without pain. The common causes include puerperal, non-puerperal, and idiopathic mastitis whereas uncommon causes like tuberculosis, filariasis, hydatid and other parasitic infections are still seen in developing countries. Imaging with digital mammography may be difficult due to pain or inadequate due to increased breast density. Ultrasound serves as the modality of choice for detailed assessment in these patients. Since the imaging features are often overlapping with malignancy, biopsy is almost always indicated. However, there are certain imaging findings that may point to the diagnosis of mastitis and can help in accurate radiologic-pathologic correlation. This article aims to illustrate the varied clinico-radiological features of patients with tropical breast infections.

Abstract
Isolated extramedullary relapse of acute lymphoblastic leukemia (ALL) in the breast is extremely rare. We herein report a case of a 38-year-old female with B cell ALL, who had isolated extramedullary relapse initially in the left breast and subsequently in the right breast, 3 and 4 years, respectively, after hematopoietic allogenic stem cell transplantation. She was successfully salvaged with bilateral whole breast radiotherapy, 24 Gy/12 fractions/2.5 weeks. This brief report highlights the importance of awareness of extramedullary leukemic relapse in the breast as one of the differential diagnoses of breast masses in the context of ALL. Since these tumors are extremely radioresponsive, radiation therapy is a safe and effective treatment option for isolated extramedullary relapse of ALL in the breast.

Abstract
Extrauterine endometrial stromal sarcoma arising from malignant transformation of the vagina is an extremely rare condition. The diagnosis is often difficult as the symptomatology and pathological features overlap with that of pelvic endometriosis. A 38 years old female presented with complaints of dyspareunia, dysmenorrhea, and painful defecation along with blood-stained vaginal discharge for a year. Examination revealed the presence of multiple brownish irregular nodules in posterior vaginal fornix and fixed tender nodules which on biopsy revealed florid vaginal endometriosis. She improved symptomatically on medical therapy. After 18 months of diagnosis, she presented again with a necrotic growth in posterior fornix, which on repeat biopsy revealed a low-grade endometrial stromal sarcoma. Laparotomy revealed a 7×5 cm mass in the pouch of Douglas, infiltrating the posterior vaginal wall and rectum. A complete cytoreductive surgery with retrograde hysterectomy, excision of posterior vaginal wall and rectosigmoid resection was done. The patient is disease-free at a follow-up of 65 months.

Abstract
The objective of this research was to study the contrast enhancement patterns of the different molecular subtypes of breast cancer on contrast-enhanced ultrasound (CEUS) using both qualitative and quantitative parameters. This prospective study included females with a single breast mass which was histopathologically proven carcinoma. B mode ultrasound (USG) and CEUS were performed in all patients during baseline assessment. Qualitative CEUS assessment encompassed enhancement pattern, presence of fill-in and washout. Quantitative assessment included measurement of peak enhancement, time to peak; area under the curve and mean transit time. A p-value < 0.05 was considered statistically significant for differentiating the subtypes. The included thirty masses were categorised into two subtypes-triple negative breast cancer (TNBC) (36.7%) and non-TNBC (63.3%) subtypes. With B-mode USG, a statistically significant difference was observed between the two groups with respect to their shape and margins. TNBC lesions showed an oval shape, circumscribed margins and peripheral nodular enhancement on CEUS with the absence of fill-in even in the delayed phase (p-value - 0.04). The two subtypes did not significantly differ in terms of quantitative perfusion parameters. The various subtypes of breast cancer therefore possess distinct contrast enhancement patterns. CEUS potentially allows differentiation amongst these molecular subtypes that may aid in radiology-pathology (rad-path) correlation and follow up of the patients.

Abstract
Tracheal tumors are rare neoplasms, most of which are malignant. Conventional bronchoscopy (CB) and biopsy are used in the primary evaluation of these tumors, while Contrast-Enhanced Computed Tomography (CECT) is usually used for assessing extraluminal extension and nodal spread. Virtual bronchoscopy, created by postprocessing the three-dimensional volume data acquired from CECT, attempts to recreate the endoluminal features as seen in CB. The complexity of tracheal surgery necessitates accurate preoperative localization of the lesion and planning. It can assist in evaluation of patients in whom CB cannot be performed and for airway assessment in a preoperative setting. Although it cannot replace CB, it can be resorted to, in specific clinical scenarios. In this pictorial essay, we aim to highlight the technique, role, and clinical utility of Virtual Bronchoscopy (VB) in tracheal tumors.

Abstract
There is paucity of literature regarding the demography, histopathology, management, and outcomes of bilateral breast cancer (BBC). We present our experience of treating 127 BBC with multimodality management. An audit of prospectively maintained computerized breast cancer database of the department of surgical oncology at a tertiary care center was performed. Demography, clinical profile, molecular sub-types, treatment patterns, and outcomes were analyzed. A total 127 patients presented with BBC between 1992 and 2019. Ninety-four had metachronous (MBBC) and 33 had synchronous breast cancer (SBBC). Most contralateral breast cancer (CBC) patients had early-stage breast cancer in comparison to the index side cancer (37% vs 32%). Ninety-four patients underwent bilateral mastectomy and only 18 patients underwent bilateral breast conservation. Seventy-one patients undergoing BCS and surgery for LABC were given postoperative radiotherapy. All patients received adjuvant chemo- and/or hormonal therapy both for index and CBC based on the stage and hormone receptor status. Thirty-three percent of patients had either locoregional or distant relapse. The 5-year overall survival (OS) and 5-year disease-free survival (DFS) of the entire cohort were 86.6% and 68.4% respectively. There was no difference in the OS and DFS between SBBC and MBBC. The incidence of BBC is expected to increase with effective diagnostic and therapeutic interventions and improving survival. Patients require individualized treatment planning in a multidisciplinary treatment setting.

Abstract
Synovial sarcoma (SS) is one of the commonest non-rhabdomyosarcoma soft tissue sarcoma with limited treatment options in the relapsed and advanced settings. The combination of gemcitabine and docetaxel has demonstrated its role predominantly in leiomyosarcoma and pleomorphic sarcomas but has not been prospectively studied in SS. This trial assesses the efficacy, tolerability and quality of life (QoL) with this regimen in metastatic/unresectable locally advanced relapsed SS.Patients and methods This was a single-arm, two-stage, phase II, investigator-initiated interventional study among patients with metastatic or unresectable locally advanced SS who had progressed after at least one line of chemotherapy. Gemcitabine 900 mg/m2 on days 1 and 8 and docetaxel 75 mg/m2 on day 8 were administered intravenously every 21 days. The primary endpoint was 3-month progression-free rate (PFR); overall survival (OS), progression-free survival (PFS), overall response rate (ORR), safety and quality of life (QoL) constituted the secondary endpoints.Results Twenty-two patients were enrolled between March 2020 and September 2021 and the study had to be closed early due to slow accrual. The study population comprised of 18 (81.8%) patients with metastatic disease and 4 (18.2%) patients with locally advanced, unresectable disease. The most common primary sites of disease were extremity in 15 (68%) and the median number of lines of prior therapies received was 1 (range 1-4). 3-month PFR was 45.4% (95% CI 24.8-66.1) and ORR was 4.5%. Median progression-free survival (PFS) was 3 months (95% CI 2.3-3.6) and median OS was 14 months (95% CI 8.9-19.0). 7 (31.8%) patients experienced grade 3 or worse toxicities, including anemia (18%), neutropenia (9%) and mucositis (9%). QoL analysis demonstrated significant decline in certain functional and symptom scales, while financial and global health scales remained stable.Conclusion This is the first prospective study on the combination of gemcitabine and docetaxel performed specifically in patients with advanced, relapsed SS. Although the accrual of patients could not be completed as planned, the therapy did produce clinically meaningful outcomes and met its primary endpoint of 3-month PFR. This result, along with the manageable toxicity profile and stable global health status on QoL analysis, should encourage further studies.Trial registration This trial was prospectively registered under the Clinical Trials Registry of India on 26/02/2020 (Registration number: CTRI/2020/02/023612).

Abstract
Purpose Cancer-related complications (CrC) and any potentially life-threatening findings detected on routine oncological imaging requires urgent intervention and needs proactive management. We conducted a retrospective study to highlight the role of imaging in the detection of CrC on computed tomography (CT)-scan while sharing our experience at a tertiary care cancer hospital. Materials and methods All the reports of the CT scans performed in our department between January 2018 and December 2019 were reviewed and the imaging findings of CrC were recorded. Only the patients who had known malignancy and underwent imaging evaluation at our centre at baseline/follow up/surveillance were included. The clinical details of the patients were recorded and the findings were classified based on the system or organ involved and also on the basis of its impact on clinical management. Results A total of 14,226 CT scans were performed during the study period, out of which 599 patients had CrC. Most of the CrC were seen involving thorax (265/599, 44.3%) followed by abdomen (229/599, 38.2%) and head and neck (104/599, 17.3%) regions. The commonly encountered CrC were pulmonary infections, superior vena cava obstruction and drug-induced lung changes. Conclusion CrC have significant impact on the course of management of cancer patients and radiologist plays an important role in early diagnosis and initiation of prompt management of many such patients. CT is an excellent modality for early diagnosis of CrC which guides the oncologist for appropriate treatment.

Abstract
BACKGROUND Sorafenib is currently one of the recommended treatments for symptomatic patients with desmoid-type fibromatosis (DTF). In this study, we aim to assess the clinical efficacy and tolerability of sorafenib in DTF patients. METHODOLOGY Patients aged>18 years with a histological diagnosis of DTF and who have received sorafenib were enroled in this prospective observational study. Demographic data, clinical profile, the initial dose of sorafenib, treatment-related toxicities, dose modifications, and responses were recorded. The primary objective was to assess the objective response rate (ORR). The secondary objectives were to evaluate progression-free survival (PFS), tolerability, and adverse effects of sorafenib. Response assessment was based on response evaluation criteria in solid tumours 1.1 criteria. Adverse effects were graded according to National Cancer Institute Common Terminology Criteria for Adverse Events version 5.0 criteria. Time to event was calculated by Kaplan-Meier analysis, and survival was compared by log-rank test. Univariate and multivariable cox regression analysis were used to find independent predictors of relapse. RESULTS A total of 104 patients were enroled in the study. The median age of the study population was 32 (range, 18-81) years, and 66.35% of patients were females. On response assessment, ORR was 46.1% and stable disease was observed in 31.7% patients. ORR was higher in the appendicular site (51.7%) compared to the abdominal site (27.2%). PFS at 1 and 2 years was 86.6% (79.6-92.7%) and 73.7% (62.4-82.8%), respectively. Two-thirds (66.6%) of patients had already received some form of treatment. At the time of analysis, 70 (67.3%) patients were continuing sorafenib. Only 4.8% stopped sorafenib due to progression, 10.5% due to intolerable adverse effects, and 17.3% due to other reasons. The common treatment-related toxicities were hand-foot skin reaction (HFSR) (89.4%), fatigue (79.8%), alopecia (70.1%), and diarrhoea (48.0%). In the patients with a starting dose of ≥400 mg (48.0% of patients), discontinuation was necessitated in 12% of patients, and further dose reduction was required in 58%, while only about 13% required dose reduction or discontinuation at a starting dose of 200 mg (51.9% of patients). Responses were not compromised due to lower starting doses. CONCLUSIONS Sorafenib has good activity in DTF, but it is associated with significant toxicity. The adverse effect profile is distinct in Indian patients with higher HFSR and alopecia. Due to the high rate of dose reduction/discontinuation with a starting dose of 400 mg, a starting dose of 200 mg may be recommended in Indian patients.

Abstract
AbstractCervical cancer is the fourth most common cancer in women globally and the second most common cancer in Indian women, more common in lower socioeconomic strata. Improvement in survival and decrease in morbidity reflect the earlier detection with screening and imaging, as well as multifactorial multimodality therapy integrating surgery, and concurrent chemoradiation therapy providing superior therapeutic benefits. Imaging plays a vital role in assessing the extent of disease and staging of cervical cancer. The appropriateness criteria of a modality are different from its availability based on infrastructure, medical facilities, and resource status. Although in an ideal situation, magnetic resonance imaging (MRI) would be of greatest value in locoregional assessment of extent of disease and fluorodeoxyglucose positron emission tomography-computed tomography for distant staging; often, an ultrasonography, chest radiograph, and bone scans are utilized, with contrast-enhanced computed tomography representing a fair superior diagnostic accuracy, and can be reported as per the RECIST 1.1 criteria. MRI is also of good utility in the assessment of residual disease, predicting response and detecting small volume recurrence. MRI offers the highest diagnostic accuracy in determining parametrial invasion and hence surgical planning; so also, MRI-guided radiation planning helps in more accurate graded radiation dose planning in radiation therapy. Stage and therapy-based surveillance imaging should be encouraged and recommended.

Abstract
Pulmonary intimal sarcoma (PAS) is a highly aggressive malignant mesenchymal tumor affecting the central pulmonary arteries. Similar clinical presentation and indeterminate laboratory parameters often result in misdiagnosis of this condition as pulmonary thromboembolism, which is a relatively common disease. Certain imaging features can however allow differentiation between these two diagnoses. We present one such case of PAS that was initially treated as pulmonary embolism; and briefly review the relevant imaging characteristics to avoid overlooking PAS especially in patients with an atypical clinical history for thromboembolism.

Abstract
AbstractUterine cancers are classified into cancers of the corpus uteri (uterine carcinomas and carcinosarcoma) and corpus uteri (sarcomas) by the AJCC staging system (eighth edition). Endometrial carcinoma is the most common amongst these with prolonged estrogen exposure being a well-known risk factor. The FIGO staging system for endometrial carcinoma is primarily surgical and includes total hysterectomy, bilateral salpingo-oophorectomy, and lymphadenectomy. Imaging is useful in the preoperative evaluation of tumor stage, especially assessment of myometrial invasion and cervical stromal extension. Dynamic contrast enhanced MRI with DWI has a high staging accuracy and is the preferred imaging modality for primary evaluation with contrast-enhanced CT abdomen being indicated for recurrent disease. PET/CT is considered superior in evaluation of lymph nodes and extra pelvic metastases.

Abstract
To compare features of clinically defined subtypes of breast cancer on mammography (MG) and ultrasonography (USG). After obtaining approval from the institute ethics committee, a retrospective observational study was performed on biopsy-proven breast cancer patients who underwent baseline MG from 2016 to 2020. MG and USG features were evaluated and the patients were classified based on immunohistochemistry profile into luminal like (LL)-oestrogen receptor (ER)/progesterone receptor (PR) + , Her2neu-; basal like (BL)-ER/PR-, Her2neu-; Her2 like (HL)-Her2neu + . A total of 479 patients (mean age, 51.4 ± 11.7 years; all females) were included: LL-198 (41.3%), BL-121 (25.2%) and HL-160 (33.3%). On MG, round shape (21/115, 18.3%, p < 0.001); circumscribed (16/115, 13.9%, p < 0.001) and microlobulated margins (28/115, 24.4%) were associated with BL tumours. Associated suspicious calcifications (96/160, 60%, p < 0.001) and skin thickening or retraction (75/149, 50.3%, p < 0.001) were more common in HL. On USG, round shape (12/95, 12.8%, p = 0.005); circumscribed (8/94, 8.5%) and microlobulated margins (44/94, 46.8%) and posterior acoustic enhancement (7/95, 7.5%, p = 0.012) were associated with BL. The logistic regression analysis revealed that spiculated margins on MG favoured LL (OR: 8.5, p = 0.001); round shape (OR: 6.8), circumscribed (OR: 10.8) or microlobulated margins (OR: 3.5) (p < 0.001 for each) favoured BL; whereas associated features of calcifications (OR: 3.3) (p = 0.019) and skin retraction or thickening (OR: 1.8) (p < 0.001) favoured HL. On USG, circumscribed (OR: 5.9, p = 0.005) or microlobulated margins (OR: 3, p < 0.001) and posterior acoustic enhancement (OR: 9.5, p = 0.006) favoured BL. Clinically defined subtypes of breast cancer show significant differences in the imaging appearances on mammography and USG. BL tumours may not show the typical imaging features of malignancy, necessitating clinicopathological correlation for accurate diagnosis.

Abstract
Aim Hemangioendotheliomas (HEs) are malignant vascular tumors with sparse descriptions in literature owing to their rarity. Study design Ours is a retrospective study among patients of advanced HEs registered between September 2015 and April 2021. Results There were 13 patients with median age 34.6 (range: 4-69 years), male preponderance (69%) and predominant subtype of epithelioid HE (76.9%). Common primary sites were viscera (46.2%) and bone (30.8%). Tyrosine kinase inhibitors (TKIs) yielded objective responses in 30% patients whereas chemotherapy only produced disease stabilization in 7.7%. Conclusion We recognize an aggressive subset of HEs with manifestations such as acute liver failure and splenic rupture. Currently no biomarkers predict the efficacy of TKIs over chemotherapy; however, TKIs showed promising outcomes in this series.

Abstract
AbstractSynthesized mammogram is a new technique that involves reconstruction of a two-dimensional (2D) image from the tomosynthesis images rather than separate acquisition of a standard 2D mammogram. The advent of a synthesized mammogram (s2D) has helped in reducing radiation exposure. The technique of back projection used in reconstruction makes the appearance of these images different from a standard 2D mammogram. Because this is a relatively new technique, it is associated with a learning curve. Hence, it is important for the new radiologists and technicians to be aware of certain common artifacts encountered while using s2D images, which may hinder interpretation. In this pictorial review, we would like to highlight the common artifacts encountered while reading synthesized mammographic images.

Abstract
Background The spectrum and significance of Variants of Uncertain Significance (VUS) mutations in breast cancer predisposition genes is poorly defined in the Indian population. Methods All new female breast cancer patients from 1 March 2019 to 28 February 2020 were screened. Those providing informed consent and without previous genetic testing were recruited. Multigene panel testing (107 genes) by next-generation sequencing was performed for all patients. Descriptive statistics was used to describe the spectrum of VUS mutations. Results Out of 236 patients recruited in the study, a VUS was detected in 89 patients (37.71%). VUS pathogenic ratio was 2.02. A total of 121 different VUS mutations in 40 different genes were detected. Fourteen patients (15.7%) had a VUS in high penetrance genes and 36 VUS mutations (29.8%) were detected in one of the genes involved in homologous recombination repair pathway. No therapeutic interventions were done based on VUS. Conclusions In this large prospective study of genetic determinants of breast cancer from India, a high prevalence of VUS (37.71%) was detected with 15.7% patients having a VUS in high penetrance genes. More evidence needs to be generated from larger multicentric studies to better understand the implications of these genetic variants and enable their reclassification.

Abstract
Objective: To evaluate the role of shear wave elastography (SWE) of suspicious axillary lymph nodes and its combination with B-mode USG in predicting nodal metastasis in breast cancer patients. Methods: Prospective observational study was performed from June 2018 to August 2020 on breast cancer patients with suspicious axillary nodes on USG. B-mode features (cortical thickness, effacement of fatty hilum, non-hilar blood flow and round shape) and SWE parameters (Emax, Emin, Emean and ESD) of the node with the thickest cortex were evaluated. Diagnostic performances of USG, SWE and their combination were estimated using pathological status of the node on biopsy as the gold standard. Results: Of the 54 patients evaluated, optimal elasticity maps were obtained in 49 nodes of 49 patients (mean age, 46.3 ± 12.1 years; 48/49 (98%) females). On biopsy, 38 nodes (77.6%) had metastasis, while 11 (22.4%) had reactive hyperplasia. Emax, Emin, Emean and ESD of both cortex and hilum were significantly higher in metastatic than reactive nodes. Emax (cortex) ≥14.9 kPa had the best diagnostic performance (sensitivity, 73.7%; specificity, 81.8%). Cortical thickness ≥6.7 mm had the best diagnostic performance among B-mode features (sensitivity, 89.5%; specificity, 72.7%). Combining cortical thickness with effacement of fatty hilum and/or non-hilar blood flow yielded sensitivity of 89.5% and specificity of 90.9%. Addition of Emax (cortex) to cortical thickness and combination of ≥2 B-mode features increased their specificities to 90.9 and 100%, respectively. Conclusions: Metastatic axillary nodes are stiffer than reactive nodes on SWE in breast cancer patients. Emax (cortex) has the best diagnostic performance in differentiating between reactive hyperplasia and nodal metastasis. Combination of Emax (cortex) and cortical thickness increases the specificity for diagnosing metastasis, especially in nodes showing only cortical thickening. Advances in knowledge: Combination of SWE and B-mode USG is highly specific for differentiating metastasis from reactive hyperplasia in suspicious nodes of breast carcinoma patients, especially in nodes with only cortical thickening.

Abstract
11554 Background: Synovial sarcoma (SS) is one of the commonest non-Rhabdomyosarcoma Soft Tissue Sarcomas (STS) in Adolescent and Young Adults. It is a chemosensitive, high-grade tumor with a tendency for local and metastatic recurrence. While the frontline therapy is doxorubicin, treatment options in later lines are scarce. Gemcitabine docetaxel combination has demonstrated its role in relapsed STS and promising potential in frontline setting in recent times. The major STS types in previous trials included leiomyosarcomas and pleomorphic sarcomas but in SS, this regimen has not been explored. We conducted this study on gemcitabine and docetaxel combination in relapsed metastatic/locally advanced unresectable SS. Methods: This is a phase II, single-arm study in patients (pts) of metastatic/locally advanced unresectable SS relapsed post atleast one line of treatment aged between 15-75 years, ECOG performance status (PS) 0-2, adequate organ function and measurable disease by RECIST 1.1. Treatment was gemcitabine 900 mg/m2 on days 1 and 8 plus docetaxel 75 mg/m2 on day 8 with G-CSF prophylaxis for maximum 6 cycles. Adverse event (AE) profile was analyzed by CTCAE 5.0, quality of life (QoL) assessed 4-weekly by EORTC QLQ-C30 questionnaire and response assessed by RECIST at 12 weeks. Primary endpoint, 3-month Progression-free survival rate (PFR) was required to be 40%. Results: 22 pts were enrolled between 3/2020 – 9/2021 with median age 32 (range 15-60 years); 13 (59%) patients were male; ECOG PS was 1 in 13 (59%) and 2 in 9. Extremity and lung were the commonest primary and metastatic sites respectively with 20 (90.9%) pts having metastases. 50% pts received the study treatment in 2nd line, 36.3% in 3rd line and the remaining in 4th line. The 3-month PFR was 45.4%, median PFS was 3 months, OS 67% at 7 months follow-up and Overall Response Rate (ORR) was 4.5% (1 PR). There was statistically significant worsening in QoL parameters of cognitive functioning, fatigue, dyspnea, appetite loss, nausea/vomiting at 12 weeks. Progression-free pts had better QoL in cognitive and emotional function, fatigue, pain and global health status. Beyond 12 weeks, 7 out of 10 non-progressors continued the treatment (1 patient each discontinued treatment due to death, change to TKI and enrolment in another trial). The most common AEs were fatigue, nausea/vomiting, mucositis, diarrhea, alopecia, anemia, transaminitis; Grade > 3 AEs (31.8%) included anemia, neutropenia, hyperbilirubinemia, transaminitis, mucositis. There was no febrile neutropenia. Conclusions: This is the first prospective study on gemcitabine docetaxel in patients of SS. The trial met its primary endpoint of 3-month PFR more than 40% which is promising in relapsed population. The improved QoL among progression-free pts is encouraging. Gemcitabine docetaxel regimen exhibits efficacy and safety to be considered for use in relapsed SS. Clinical trial information: CTRI/2020/02/023612.

Abstract
Introduction Multiphase MRI liver is the gold-standard imaging modality for staging hepatocellular carcinoma (HCC) in patients with cirrhosis. Often, small HCCs diagnosed on multiphase MRI are occult on B-mode ultrasound and multiphase CT (MPCT) and thus pose a challenge for loco-regional therapy. We adapted the technique of lipiodol CT in treating two such patients of small HCC. Methods Lipiodol-CT involved an intra-arterial lipiodol injection through the hepatic artery followed by a noncontrast CT liver. CT delineated small, hyperdense, lipiodol-laden hepatic nodules, which served as a target for executing ablation of the nodule and also revealed the true disease stage by depicting the additional number of tumors in the liver. Results Case one was a 51-year female, known case of chronic hepatitis C who presented with ascites for two months. She was diagnosed with a small HCC (LI-RADS-4) in a cirrhotic liver on multiphase MRI. Percutaneous radiofrequency ablation was planned, but the mass was not located on ultrasound or multiphase CT. Lipiodol-CT was undertaken, which delineated the lipiodol-laden small HCC, which served as a target for executing ablation. Case 2 was a 55-year male, Child-Pugh A cirrhotic, who had undergone right extended hepatectomy for hepatitis B-related HCC. Follow-up MRI revealed a 5 mm segment III nodule, which had increased in size on repeat MRI at 3 months (LI-RADS-4). This nodule, too, was occult on both ultrasound and MPCT. Lipiodol CT revealed additional multiple, variable-sized lipiodol-laden nodules in the liver remnant. Treatment of trans-arterial chemoembolization was performed at one month. Both patients showed complete response to treatment. Conclusion: Lipiodol CT can be safely used in a new role of facilitating treatment of small HCCs diagnosed on MRI but occult on ultrasonography and MPCT.

Abstract
Background Aggressive angiomyxoma (AAM) is a rare mesenchymal tumor predominantly affecting the pelvis and perineum of females. Due to its variable clinical presentation, it is often misinterpreted and treated as other pathologies like Bartholin gland cyst, vulvar abscess, and hernia. The tumor is locally infiltrative, making its complete surgical removal difficult. Aim The aim of the study is to highlight and illustrate the imaging and pathological features of AAM. Materials and Methods After obtaining clearance from the Institutional Ethics Committee, a retrospective study was conducted on patients with histopathological diagnosis of AAM, presenting to the dedicated sarcoma clinic between 2016 and 2019. The demographic, clinical, radiological, pathological, and treatment details were obtained from the institute's database. The magnetic resonance imaging (MRI) and computed tomography images were reviewed to assess different imaging parameters. Follow-up imaging was assessed for residual or recurrent mass in the pelvis or perineum and distant metastasis. Results A total of four patients were included with an age range of 28 to 50 years. The baseline MRI of these four patients shows pelvic mass extending into the perineum, infiltrating along the surrounding fascial planes with the characteristic laminated appearance on T2-weighted image and gradual intense enhancement following contrast administration. All patients had residual disease post-surgery and were put on hormonal therapy. Conclusion AAMs are locally aggressive, rarely metastasizing mesenchymal tumor that has a specific predilection for the perineum and pelvis of females. MRI features like laminated or striated appearance, post-contrast enhancement, and finger-like infiltrating projections should raise the suspicion of the diagnosis on baseline imaging.

Abstract
The International Federation of Gynecology and Obstetrics (FIGO) staging system of carcinoma cervix saw a radical change in 2018 with the inclusion of cross-sectional imaging tools for the assessment of disease extent and staging. One of the major revisions is the inclusion of lymph node status, detected either on imaging or pathological evaluation, in the staging system. The changes were based on long-term patient follow-up and survival rates reported in literature. Thus, it becomes imperative for a radiologist to be well versed with the recent staging system, its limitations, and implications on the patient management.

Abstract
OBJECTIVE To evaluate the role of axillary ultrasonography (axUS) and ultrasound-guided pre-operative wire localisation of pre-treatment positive clipped node (CN) for prediction of nodal response to neoadjuvant chemotherapy (NACT) in node positive breast carcinoma patients. METHODS AND MATERIALS A prospective study was conducted between June 2018 and August 2020 after Ethics Committee approval. Breast carcinoma patients (cT1-cT4b) with palpable axillary nodes (cN1-cN3) and suitable for NACT were recruited after written informed consent. Single, most suspicious node was biopsied and clipped. Nodal response to NACT was assessed on axUS. Wire localisation of CN was performed prior to axillary lymph node dissection (ALND). Diagnostic performances of axUS and CN excision were assessed. RESULTS Of the 69 patients evaluated, 32 patients (mean age, 43.5 ± 11.8 years; females, 31/32 [97%]; pre-menopausal, 18/32 [56.3%]) with metastatic nodes who received NACT were included. Nodal pathological complete response rate was 34.4% (11/32) overall and 70% (7/10) in patients with ≤2 suspicious nodes on pre-NACT axUS. False-negative rates (FNRs) of axUS and CN excision were 4.8% and 28.6% respectively. Combination of post-NACT axUS and CN excision had an FNR of 4.8% overall and 0% in patients with ≤2 suspicious nodes on pre-NACT axUS. CONCLUSION Combination of AxUS and ultrasound-guided wire localisation of pre-treatment positive CN has high diagnostic accuracy for nodal restaging after NACT in node positive breast cancer patients. ADVANCES IN KNOWLEDGE Addition of axUS assessment to wire localisation of CN reduces its FNR for detecting residual metastasis after NACT.

Abstract
INTRODUCTION Primary intravenous leiomyosarcomas are rare vascular tumors with aggressive disease biology. The diagnosis and management have been challenging as little data exist from large databases. METHODS A literature search was done to identify all cases of primary leiomyosarcomas in the last five years. Clinicopathological features and management strategies were evaluated. RESULTS The median age was 53 years, predominantly females (2.5:1), presenting as metastases in up to 12.1% cases. Most tumors were locally advanced with a median size of 10cm. Inferior vena cava involvement from renal veins to infrahepatic veins remains the most frequent site (57.1%cases) while nearly half (52.8%) proceeded for surgery without histological proof. Most patients could undergo upfront resection (88.0%) with few patients receiving neoadjuvant chemotherapy (4.3%) or neoadjuvant radiotherapy (2.2%). Significant multivisceral resections included right nephrectomy (41.3%), liver resection (25.7%) and left nephrectomy (2.2%). Most patients (91.8%) needed an inferior vena cava graft placement with remarkable microscopically negative margins (85.5% cases). Doxorubicin and ifosfamide were the most frequently used combination chemotherapy regimens in both pre and postoperative settings with partial responses. The median overall and disease free survival among operated patients was 60 months and 28 months respectively. In multivariate analysis large tumor, extensive inferior vena cava involvement, and need for adjuvant chemotherapy appeared significant predictors for overall survival. CONCLUSIONS Aggressive upfront surgical resection with clear margin remains the key for long-term survival. Doxorubicin-based regimens were preferred as neoadjuvant chemotherapy while adjuvant treatment with chemotherapy, radiotherapy, or both may be considered in high-risk patients.

Abstract
Spindle cell carcinoma or sarcomatoid carcinoma (SC) has been recently defined as a monoclonal dedifferentiated form of conventional squamous cell carcinoma (SCC) and termed as spindle cell (sarcomatoid) squamous carcinoma as per the current World Health Organization (WHO) classification. Although the frequency of SC of the breast, larynx, esophagus, and lungs has been reported, the frequency of oral SC with rhabdo-myosarcomatous dedifferentiation of the maxilla is unknown yet because of the less number of reported cases. Microscopic features of spindle cell carcinoma resemble many benign and malignant oral lesions. Therefore, a careful depiction with the help of routine hematoxylin and eosin along with immunohistochemistry using appropriate markers is necessary to diagnose spindle cell carcinoma. SC is itself a rare entity accounting for <1% of SCC; however, rhabdo-myosarcomatous dedifferentiation is exceptional; therefore, our aim is to highlight this extremely rare entity. This article focuses on SC with rhabdo-myosarcomatous dedifferentiation; other than rhabdomyosarcoma, with an emphasis on strategies to resolve the diagnostic dilemmas these tumors may present.

Abstract
Background The burden of hereditary breast cancer in India is not well defined. Moreover, genetic testing criteria (National Comprehensive Cancer Network [NCCN] and Mainstreaming Cancer Genetics [MCG] Plus) have never been validated in the Indian population. Methods All new female breast cancer patients from 1st March 2019 to 28th February 2020 were screened. Those providing informed consent and without previous genetic testing were recruited. Multigene panel testing (107 genes) by next-generation sequencing was performed for all patients. The frequency of pathogenic/likely pathogenic (P/LP) mutations between patients qualifying and not qualifying the testing criteria was compared and their sensitivity was computed. Results Overall, 275 breast cancer patients were screened and 236 patients were included (median age 45 years); 30 patients did not consent and 9 patients previously underwent genetic testing. Thirty-four (14%) women had a positive family history and 35% had triple-negative breast cancer. P/LP mutations were found in 44/236 (18.64%) women; mutations in BRCA1 (22/47, 46.8%) and BRCA2 (9/47, 19.1%) were the most common, with 34% of mutations present in non-BRCA genes. Patients qualifying the testing criteria had a higher risk of having a P/LP mutation (NCCN: 23.6% vs. 7.04%, p = 0.03; MCG plus: 24.8% vs. 7.2%, p = 0.01). The sensitivity of the NCCN criteria was 88.6% (75.4–96.2) and 86.36% (72.65–94.83) for MCG plus. More than 95% sensitivity was achieved if all women up to 60 years of age were tested. Cascade testing was performed in 31 previous (16/44 families), with 23 testing positive. Conclusions The frequency of P/LP mutations in India is high, with significant contribution of non-BRCA genes. Testing criteria need modification to expand access to testing. Supplementary Information The online version contains supplementary material available at 10.1245/s10434-021-10870-w.

Abstract
AIM Dermatofibrosarcoma protuberans (DFSP) accounts for less than 2% of all soft-tissue sarcomas. PATIENTS & METHODS We retrospectively reviewed our database for patients with locally advanced or metastatic DFSP who had presented to our clinic between January 2016 and January 2020. RESULTS We identified a total of 14 patients, of whom ten had sarcomatous transformation. Eleven cases had metastatic disease and three were locally advanced. The initial partial response rate to first-line imatinib was 76.9% and the overall median progression-free survival on imatinib was 15 months. CONCLUSION We had a high proportion of patients with sarcomatous transformation, in contrast to their relative rarity in the West. While most patients had initial good responses to imatinib, second-line therapies were not as effective.

Abstract
Background
There is sparse literature on trabectedin in advanced soft-tissue sarcomas from developing world. It would be interesting to know about use and outcomes of trabectedin in Indian patients.
Method
In a retrospective study, consecutive patients treated with trabectedin from 2016 to 2019 were analyzed. Patients with L-sarcomas were treated at a dose of 1.5 mg/m
2
, while those with translocation-related sarcomas were treated at a dose of 1.2 mg/m
2
as a 24-hour infusion through peripherally inserted central catheter line. From July 2019, infusions were administered through an ambulatory elastomeric pump, while before that patients were admitted for 24 hours. We used SPSS version 23.0 for statistical calculation.
Result
A total of 20 patients received trabectedin with a total of 116 infusions. The median age was 46 years (range: 22–73 years). The male (
n
= 11, 55%) and female patients were almost equal (
n
= 9, 45%). Thirteen patients (65%) had Eastern Cooperative Oncology Group Performance Status 1. Majority of the patients had leiomyosarcoma (
n
= 8, 40%); remaining comprised of liposarcoma (3, 15%), translocation-related sarcomas excluding myxoid liposarcoma (
n
= 8, 40%) and others (
n
= 1,5%). Most common site was extremity (
n
= 11, 55%) followed by retroperitoneal (
n
= 3, 15%), visceral (
n
= 3, 15%), and others (
n
= 3,15%). Median number of previous lines received was 2 (range: 0–4). Median number of trabectedin cycles received was 4 (range: 1–17). Best response assessed was stable disease (
n
= 10, 50%), progressive disease (
n
= 6, 30%), partial response (
n
= 1, 5%), and not assessed in 3 patients. After a median follow-up of 19 months, median progression-free survival was 4 months.
Conclusion
In this heavily treated population (composed of L-sarcomas and translocation-related sarcomas) with many patients with poor performance status, the outcome with trabectedin is in synchrony with literature. However, the need of 24-hour admission might deter quality of life. Elastomeric pump seems to be a reasonable alternative to admission and can be a breakthrough in administering trabectedin, especially in developing countries.

Abstract
Breast interventions primarily comprise of biopsy of the suspicious breast lesions to obtain accurate pathological diagnosis. Generally, image-guided breast biopsy is required for nonpalpable lesions, however, even in palpable lesions, image-guided biopsy should be performed as it improves the accuracy of diagnosis. Image-guided breast interventions have progressed well beyond biopsy, making the radiologist an important part of the multidisciplinary management of breast cancer. Preoperative localization of nonpalpable abnormalities guides optimal surgical excision to obtain negative margins without sacrificing the normal tissue. Ablative procedures for breast cancer treatment such as radiofrequency ablation (RFA) and high-intensity focused ultrasound ablation can sometimes replace surgery in older patients with comorbidities. This article enumerates and describes the expanding spectrum of image-guided interventions performed by breast radiologist.

Abstract
BACKGROUND & OBJECTIVES Imaging has been added to the International Federation of Gynecology and Obstetrics (FIGO) 2018 staging system of cervical carcinoma. This study was performed to assess the impact of imaging in staging and to ascertain the prevalence and pattern of nodal metastasis on contrast-enhanced computed tomography (CECT) in patients with cervical carcinoma who were treated based on FIGO 2009 staging system. METHODS This retrospective study was conducted to evaluate all patients with biopsy-proven cervical carcinoma who underwent CECT of abdomen at a tertiary cancer centre in north India from April 2017 to April 2019 and for whom either baseline or follow up scans were available. In patients with enlarged or necrotic lymph nodes, the location, size and pattern of infiltration of adjacent organs were recorded. RESULTS A total of 602 patients of cervical carcinoma had undergone CT during the study period, of whom 138 (22.9%) underwent CT at baseline and 464 (77.1%) patients during follow up. The FIGO (2009) stage distribution at the time of presentation was stage IB: 109 (18.1%); stage IIA: 14 (2.3%), stage IIB: 118 (19.6%), stage IIIA: 12 (2%), stage IIIB: 277 (46%), stage IVA: 20 (3.3%) and stage IVB: 52 (8.6%). Ninety of the 138 (65.22%) patients underwent a stage shift according to the FIGO 2018 because of the presence of enlarged lymph nodes at baseline scan. Sixteen (2.7%) patients had infiltrative nodal masses most commonly involving the blood vessels (n=14) followed by ureter (n=8), bones (n=5), muscle and bowel (n=3, each). The majority (14/16) of these patients presented with vague abdominal pain, discomfort and vomiting, while two had bone pain. INTERPRETATION & CONCLUSIONS CECT at baseline helps in accurately assessing the stage in cervical carcinoma. It helps in the identification of lymph node metastasis in cervical carcinoma, which is crucial for guiding accurate management.

Abstract
The 2018 revised International Federation of Gynaecology and Obstetrics (FIGO) staging of cervical cancer has brought about a paradigm shift by offering the option of adding imaging and pathology to clinical staging. This makes it applicable to all types of resource situations across geographies with implications for all stakeholders, including gynaecologists, gynaecologic oncologists, radiologists, pathologists and radiation and medical oncologists. The new staging classification has more granularity, with three sub-stages of stage IB and a new category of stage IIIC for all cases with lymph node (LN) involvement. The major limitations of clinical staging were inaccurate assessment of tumour size and inability to assess pelvic and para-aortic LNs with the limited investigations permitted by FIGO to change the stage. This resulted in understaging of stages IB-III, and overstaging of stage IIIB, which has been largely overcome by incorporating imaging findings. Although any imaging modality can be used, magnetic resonance imaging appears to be the best imaging modality for early-stage disease owing to its better soft-tissue resolution. However, the use of contrast-enhanced computed tomography or ultrasonography are also feasible options, depending on the availability and resources. But wherever pathological evaluation is possible, it supersedes clinical and radiological findings.

Abstract
Context Alveolar soft part sarcoma (ASPS) is a rare soft tissue tumor most commonly occurring in deep intramuscular plane of lower extremities of adolescents and young adults. It is a highly vascular, slow growing tumor with malignant potential having lung as the most common site of metastases at the time of presentation. Aims The aim is to review the imaging findings of ASPS and determine characteristic imaging features of this rare tumor. Materials and Methods Sixteen patients having histopathological diagnosis and preoperative imaging of ASPS attending the dedicated sarcoma clinic at our institute were included in the study. The demographic, clinical, and imaging data were retrieved from the case records and then evaluated for characteristic imaging features which may raise suspicion of ASPS. Results The patients ranged from 3 to 72 years of age and with a slight male preponderance. Of the eight CECTs evaluated, 62.5% tumors showed well-defined lobulated margins, 87.5% cases showed intense enhancement with presence of feeder vessels. On CEMRI of 10 patients, 70% had well circumscribed lobulated margins with intense enhancement and tortuous flow voids in most of them. All cases showed T2 hyperintense signal. Fourteen of 16 (87.5%) patients had metastatic disease with lung as the most common site (92.8%). Conclusion ASPS is a rare soft tissue sarcoma seen in children and young adults. Imaging may mimic a vascular malformation due to the presence of tortuous feeders. Misdiagnosis at an early stage may lead to later metastatic presentation of the disease, thus emphasizing the need to suspect it on imaging.

Abstract
OBJECTIVE This study evaluated the utility of 18F-fluorodexoyglucose (18F-FDG) positron emission tomography/computed tomography (PET/CT) in staging, grading, and prognostication of Stage III and IV soft tissue sarcomas (STSs). METHODS Forty patients (Median age = 32.5 years; 25 men) with histologically proven STSs, prospectively underwent 18F-FDG-PET/CTs at baseline. Three-dimensional region of interests were drawn encompassing the lesions to calculate standardized uptake values (SUVs) and metabolic tumor volumes (MTVs). After segmentation, Haralick statistical texture analysis was performed. Follow-up was available for 35 patients. Survival at 6 months was 71.4% and at 1 year was 57.1%. RESULTS American Joint Committee on Cancer Stage III was seen in 23 and Stage IV in 17 patients. None of the baseline quantitative and semi-quantitative parameters could predict response or progression. Only reduction in SUVmax in interim PET/CT correlated with baseline SUVmax (Spearman's Rho = 0.533; P = 0.019). Textural parameters namely 'contrast' in CT (P = 0.039) and 'difference entropy' in PET/CT (P = 0.051) could differentiate intermediate from high-grade lesions, with corresponding area under curves being 0.736 (0.533-0.889) and 0.700 (0.518-0.882). M1 disease [Hazard ratio (HR): 3.184 (1.179-8.595); P = 0.022], absence of surgical treatment [HR 0.305 (0.106-0.873), P = 0.027 with surgery], lower MTV/total tumor volume (TTV) [HR: 0.975 (0.953-0.997; P = 0.028] and progressive disease in interim PET/CT [3.483 (0.898-13.515); P = 0.056] were predictors of lower survival in univariate analysis. Only M1 disease was found to be reaching significance in multivariate analysis [HR = 2.683 (0.949-7.580); P = 0.063]. Baseline PET/CT changed management in 12.5% of patients [compared to local-imaging and high-resolution CT chest]; with detection of extra-pulmonary metastases. Though, interim and end of treatment PET/CTs detected more metastatic lesions, management was not impacted. CONCLUSION 18F-FDG-PET/CT allows for more accurate M-staging in late-stage STSs, which in turn influences the option of curative surgical resection and thus impacts patient prognosis. Lower baseline MTV/TTV and progression in interim PET/CT are also associated with lower survival. Textural analysis may have a role in noninvasive grading.

Abstract
BACKGROUND Cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) has recently emerged as a viable management option for peritoneal surface malignancy (PSM). CRS and HIPEC is a complex, multidisciplinary and resource-intensive surgical procedure. It has a steep learning curve and is associated with significant morbidity and mortality. The expertise is mostly limited to few dedicated high-volume centers located in developed countries. We present a single institutional experience of 232 cases of CRS and HIPEC performed at a tertiary care cancer center in a low- and middle-income country (LMIC). METHODS A multidisciplinary PSM program was initiated in 2015 at a high-volume public-sector tertiary care cancer center in North India catering largely to patients belonging to low- and middle-income groups. Perioperative protocols were developed, and a prospective structured database was created to capture data. All patients undergoing CRS and HIPEC between January 2015 and December 2020 were identified, and the data was retrospectively analyzed for clinical spectrum, surgical details, and perioperative morbidity and mortality. RESULTS Two hundred and thirty-two patients underwent CRS and HIPEC during the study period. Epithelial ovarian carcinoma (56.5%) was the most common malignancy treated, followed by pseudomyxoma peritonei (18.5%), colorectal carcinoma (13.4%), and malignant mesothelioma (5.6%). Optimal CRS could be achieved in 94.4% of patients. Cisplatin and mitomycin were the most common drugs used for HIPEC. A total of 28.0% of patients had morbidity including deep vein thrombosis, subacute intestinal obstruction, sepsis, burst abdomen, lymphocele, urinoma, acute renal failure, and enterocutaneous fistula. The overall treatment-related mortality was 3.5%. CONCLUSIONS Results of the current study indicate that it is feasible to establish a successful CRS and HIPEC program for PSM in government-funded hospitals in LMIC facing resource constraints. The most common indication for CRS and HIPEC were carcinoma of the ovary followed by pseudomyxoma peritonei and colorectal carcinoma. Overall morbidity and mortality in the current series are comparable to global standards, reported from high-income countries. A protocol-based multidisciplinary team approach, optimal patient selection, and surgical expertise can help achieve optimal outcomes in government-funded hospitals in LMIC.

Abstract
e18617 Background: The study evaluated the prevalence & impact of sarcopenia in gastroesophageal cancer (GC) & lung cancer (LC) patients undergoing resection. Methods: An observational prospective study was conducted in department of surgical oncology, AIIMS, New Delhi. All patients aged under 65 years with resectable GC & LC were included. Skeletal muscle index (SMI) using cross-sectional CT images at the level of L3 & Hand grip strength (dynamometer) were used to assess sarcopenia. Random benign patients with CT images were used as control group. Patients were categorized into sarcopenic and non-sarcopenic and outcome parameters were compared. Results: In the study population (n = 66), GC & LC constituted 44 (66.67%) & 22(33.33%) respectively. Mean age was 53.4 years. The prevalence of sarcopenia based on the combined method (CT imaging & handgrip strength) was 57.58%, CT based sarcopenia was 33.34% & handgrip strength-based sarcopenia was 43.93%. Mild and moderate sarcopenia was seen in 37.88% (n = 25) & 19.7 % (n = 13) respectively. Among patients with GC, prevalence of sarcopenia was 59.09% by combined method, 36.36% and 43.18% by CT based method alone & handgrip strength-based method alone respectively. Among LC prevalence of sarcopenia was 54.54% by combined method, 27.27% and 45.45% by CT based & handgrip-based method. The concordance between CT muscle mass & grip strength was 62.12%. Most female patients had weak handgrip strength despite having normal SMI. In control group (n = 44) mean age was 54.5 years, the prevalence of CT based sarcopenia was 34.09%. Weight loss history & BMI correlated with the degree of sarcopenia. Out of 66 patients 13% (n = 9) patients were unresectable. Moderate sarcopenia group had more statistically significant (P -0.02) unresectable disease compared to mild and non-sarcopenic groups. In postoperative period, sarcopenic group (64.51% vs 38.36 %) had more grade 2 complications though statistically insignificant. There was no difference in hospital stay between the two groups. In patients with GC , postoperative respiratory complication occurred in 11.53% (n = 3) of sarcopenic patients and 5.5%(n = 1) of non-sarcopenic patients, anastomotic leak occurred in 7.69% (n = 2) of sarcopenic patients and 5.5% (n = 1) of nonsarcopenic patients. Conclusions: The prevalence of sarcopenia is higher in patients with gastroesophageal cancer compared to lung cancer. The important factors that affect the sarcopenia include age and body mass index and weight loss history. The study has showed a trend towards increased post-operative complications and increased unresectable cases in patients with mild to moderate sarcopenia. Further larger studies are required to validate if sarcopenia can be used as an adjunct to predict resectability and post-operative outcomes.

Abstract
11574 Background: Desmoid type fibromatosis (DTF) is a rare benign neoplasm with infiltrative growth and high local recurrences. Due to long disease course, unpredictable growth pattern, and low mortality, using only survival outcomes may be inappropriate. In this study we assessed the impact of DTF on health related quality of life (HRQoL). Methods: This was a cross-sectional study done in patients with DTF. The study participants were asked to fill the EORTC QLQ-C30, GAD-7 and PHQ- 9 q uestionnaires to assess HRQoL, anxiety and depression . Outcomes were also compared with healthy controls. Results: 204 subjects (102 DTF patients and 102 healthy controls) were recruited. Study parameters have been summarized in Table. Appendicular skeleton (limbs + girdle) was most commonly involved in 59 % patients and abdominal wall or mesentery was involved in 22.5 %. Patients have received median of 2 lines of therapy. 54 % patients were currently on sorafenib and 41 % were under active surveillance. Mean global health status in DTF patient 65.58 ± 22.64, was significantly lower than healthy controls. Similarly, DTF patients scored low on all functional scales except cognitive functioning. Symptom scale showed significantly higher symptom burden of fatigue, pain, insomnia and financial difficulties. Anxiety & depression was observed in 39.22 % and 50 % of DTF patients respectively. DTF patients had higher rates of mild, moderate and severe anxiety and depression compared to healthy controls. No difference was observed based on site of disease. Conclusions: DTF patients have significant symptom burden, poor functioning, and heightened anxiety and depression. Patient reported outcomes should be routinely used to assess treatment efficacy in DTF patients.[Table: see text]

Abstract
Breast cancer is emerging as the most common malignancy in Indian women. Mammography is one of the few screening modalities available to the modern world that has proved itself of much use by aiding early detection and treatment of non-palpable, node-negative breast cancers. However, due to its two-dimensional nature, many cases of malignancies are still missed, to be detected at a later date or by an alternate modality. In 2011, FDA approved the supplemental use of digital breast tomosynthesis (DBT) in screening and diagnostic set ups. The acquisition of multiple low-dose projection images of the compressed parenchyma provided a 'third' dimension to the mammogram whereby the breast tissue could be seen layer by layer on the workstation. It improves cancer detection rate, and reduces recall rate and false-positive findings by improving lesion characterization. The current review discusses the principle of DBT with a comprehensive study of the literature.

Abstract
Inflammatory myofibroblastic tumors (IMT) are rare soft tissue tumors of intermediate malignant potential occurring usually in children and adolescents. Treatment options for advanced diseases are limited. A 35-year-old lady presented to us with fever, cough and decreased appetite. On evaluation, she was diagnosed with left lung IMT. She underwent surgery and developed recurrence with pleural nodules after two years. Immunohistochemistry showed positivity for ALK (diffuse). Since recent evidence suggested that crizotinib is effective in advanced IMT with 50% response rates, she was treated with crizotinib 250mg BD with which she had a complete radiological response at three months. She has completed one year of treatment thus far and continues to be in complete remission. Treatment with ALK inhibitors like crizotinib has brought about a paradigm shift in the management of advanced ALK-positive IMT's with excellent clinical responses which are durable in a majority of cases.

Abstract
Mycobacterium tuberculosis (Mtb) employs diverse strategies to survive inside the host macrophages. In this study, we have identified a conserved hypothetical protein of Mtb; Rv0674, which is present in the mitochondria of the host cell. The genetic knock-out of rv0674 (Mtb-KO) showed increased growth of Mtb. The intracellular infection with recombinant Mycobacterium smegmatis (MSMEG) expressing Rv0674 (MS_Rv0674), established that the protein is involved in promoting the apoptotic cell death of the macrophage. To investigate the mechanism incurred in mitochondria, we observed that the protein physically interacts with the control region (D-loop) of the mitochondrial DNA (LSP and HSP promoters of the loop) of the macrophages and facilitates the increased expression of mRNA in all the complexes of mitochondrial encoded OXPHOS subunits. The changes in OXPHOS levels corroborated with the ATP synthesis, mitochondrial membrane potential and superoxide production. The infection with MS_Rv0674 confirmed the role of this protein in effecting the intracellular infection. The fluorescent and confocal microscopy confirmed that the protein is localized in the mitochondria of infected macrophages and in the cells of BAL of TB patients. Together these findings indicate towards the novel function of the protein which is unlike to the earlier established mechanisms of mycobacterial physiology.
