Abstract
PURPOSE Adherence to international antiemetic prophylaxis guidelines like those of ASCO can result in better control of chemotherapy-induced nausea and vomiting; however, the extent of implementation of such guidelines in India is unknown. Therefore, this survey was planned. METHODS This study was an anonymized cross-sectional survey approved by the ethics committee. Survey items were generated from the clinical questions given in the ASCO guidelines. The survey was disseminated through personal contacts at an oncology conference and via e-mail to various community oncology centers across India. The B1, B2, and B3 domains included questions regarding the optimal antiemetic prophylaxis for high, moderate, and low-minimal emetogenic regimens. RESULTS Sixty-six (62.9%) of 105 responded and 65 centers (98.5%) were aware of the published guidelines. The partial, full, and no implementation scores were 92.5%, 4.5%, and 3.0%, respectively. Full implementation was better for the low-minimal emetogenic regimens (34.8%) than the highly emetogenic regimens (6.1%). The three most frequent reasons for hampered implementation of ASCO guidelines in routine chemotherapy practice cited by centers were a lack of sensitization (26 centers; 39.4%), lack of national guidelines (12 centers; 18.2%), and lack of administrative support (10 centers; 15.2%). CONCLUSION Awareness regarding ASCO antiemetic guidelines is satisfactory in Indian oncology practices; however, there is a need for sensitization of oncologists toward complete implementation of these guidelines in their clinical practice.

Abstract
BACKGROUND Poor-risk advanced Renal cell carcinoma (RCC) are an under-evaluated and difficult to treat subset of patients with poor prognosis. While Temsirolimus is the approved first line therapy for this category, Tyrosine kinase inhibitors (TKIs) are also commonly uses as initial treatment. We present an analysis of poor-risk advanced RCC treated in our institute. MATERIALS AND METHODS Patients diagnosed as poor-risk (as per Heng criteria) advanced RCC from June 2008 to December 2015 were analysed for baseline demographics, treatment received, toxicity (primarily Grade 3 and Grade 4), response rates (RR) and survival. RESULTS 60 patients (43 males, 17 females) with a median age of 53 years were included for final analysis. Median ECOG PS was 1, clear cell was the predominant histology (63.3%), and 46.7% of patients had greater than 2 sites of metastases. Sorafenib, Sunitinib, Temsirolimus and Pazopanib were used to treat 43.3%, 36.7%, 8.3% and 6.7% of patients respectively, while 3 patients were offered upfront best supportive care. Common adverse events included skin rash (31.5%), HFS (Grade 2 and 3 - 30.8%), mucositis (26.3%), hypertension (24.5%), and dyslipidaemias (22.8%). 41 patients were available for response - overall response rate observed was 15%, while clinical benefit rate was 50%. Median progression free survival was 5.78 months (4.67-6.89) and median overall survival (OS) was 10.05 months (7.31-12.79). CONCLUSION A majority of poor-risk metastatic RCC patients in our study were treated with TKIs and the survival outcomes appear to suggest that this strategy is a feasible alternative to Temsirolimus in the Indian setting.

Abstract
INTRODUCTION Unlike the developed countries, there is a lack of good epidemiologic data for testicular germ cell tumors (GCTs) in India with majority presenting in advanced stage. This study aims to elaborate on the epidemiology of testicular GCTs and response to standard first-line chemotherapy (CT). METHODS GCTs treated at our center from January 2013 to June 2014 were retrospectively analyzed. Patients underwent orchidectomy either outside or at our hospital. Based on stage and risk group, standard CT (bleomycin, etoposide, and cisplatin/etoposide and cisplatin/carboplatin AUC7) and radiotherapy were given as appropriate. Response was calculated based on the Response Evaluation Criteria in Solid Tumors. Statistical analysis was performed using SPSS 18 software. RESULTS Fifty nonseminomatous germ cell tumor (NSGCT) and 36 of SGCT cases were studied. 30%, 46%, and 64% of NSGCT and 11%, 28%, and 22% of SGCT had N2, N3, and M1 diseases, respectively. The mean nodal size was 7 cm (1.5-19) in NSGCT and 5.5 cm (1.3-11) in SGCT. As per the International Germ Cell Cancer Collaborative Group classification, in patients with metastatic disease, 9% of NSGCT were good, 53% were intermediate, and 38% were poor risk whereas 75% of SGCT were good and 25% were intermediate risk. Following CT among NSGCT, 5% and 71% had radiologic complete response (CR) and partial response (PR), respectively. Among SGCT, 46% and 38% had radiologic CR and PR, respectively. 22%, 53%, and 13% of NSGCT and 12%, 24%, and 20% of SGCT developed febrile neutropenia, Grade 3 or 4 hematological and nonhematological toxicities, respectively, after standard chemotherapy. CONCLUSIONS GCTs in India present with high nodal and high-risk diseases wherein the standard first-line CT may not be adequate as curative therapy; however, significant chemotoxicity is also a hindrance.

Abstract
BACKGROUND To assess the response rate and impact of neoadjuvant chemotherapy (NACT) in advanced carcinoma of the hypopharynx and larynx. MATERIALS AND METHODS This is a retrospective case series of 80 patients with locally advanced laryngopharynx carcinoma who received NACT from April 2010 to October 2011 at our tertiary care center. The patients received NACT either for achieving resectability or for organ preservation. RESULTS Majority of the patients (60%) had T4 a disease. Grade 3 and 4 neutropenia was seen in 18%, febrile neutropenia in 4%, mucositis in 4%, diarrhea in 5%, and vomiting in 3% patients. Resectability could be achieved in 34%, and larynx was preserved in 51% patients at a mean follow-up of 13 months. CONCLUSIONS NACT was safe with acceptable toxicity. Majority of the patients who achieved resectability had oropharyngeal involvement. NACT followed by concurrent chemoradiotherapy could provide a high rate of organ preservation.

Abstract
BACKGROUND Lung cancer is the leading cause of cancer-related deaths across the world. In this study, we present therapeutically relevant genetic alterations in lung adenocarcinoma of Indian origin. MATERIALS AND METHODS Forty-five primary lung adenocarcinoma tumors were sequenced for 676 amplicons using RainDance cancer panel at an average coverage of 1500 × (reads per million mapped reads). To validate the findings, 49 mutations across 23 genes were genotyped in an additional set of 363 primary lung adenocarcinoma tumors using mass spectrometry. NIH/3T3 cells over expressing mutant and wild-type FGFR3 constructs were characterized for anchorage independent growth, constitutive activation, tumor formation and sensitivity to FGFR inhibitors using in vitro and xenograft mouse models. RESULTS We present the first spectrum of actionable alterations in lung adenocarcinoma tumors of Indian origin, and shows that mutations of FGFR3 are present in 20 of 363 (5.5%) patients. These FGFR3 mutations are constitutively active and oncogenic when ectopically expressed in NIH/3T3 cells and using a xenograft model in NOD/SCID mice. Inhibition of FGFR3 kinase activity inhibits transformation of NIH/3T3 overexpressing FGFR3 constructs and growth of tumors driven by FGFR3 in the xenograft models. The reduction in tumor size in the mouse is paralleled by a reduction in the amounts of phospho-ERK, validating the in vitro findings. Interestingly, the FGFR3 mutations are significantly higher in a proportion of younger patients and show a trend toward better overall survival, compared with patients lacking actionable alterations or those harboring KRAS mutations. CONCLUSION We present the first actionable mutation spectrum in Indian lung cancer genome. These findings implicate FGFR3 as a novel therapeutic in lung adenocarcinoma.

Abstract
Aims: Docetaxel, Doxorubicin, Cyclophosphamide (TAC) is an intensive chemotherapy regimen; however, being highly myelosuppressive, its usage is limited in developing countries and hence merits exploration for feasibility and efficacy. Materials and Methods: This was a retrospective audit of medical records of breast cancer patients receiving TAC chemotherapy) from 2004 to 2008. Demographic details, toxicity, and outcome analysis were carried out. Results: A total of 133 patients (126 in [neo] adjuvant and 7 in metastatic setting) received TAC chemotherapy. The median age was 45 (21–67) years; 31% had coexisting diabetes and 12% hypertension. The delivered dose intensity was 94%. Discontinuation rate was 21/133 (15.8%) and the most common reason was hematological toxicity. There were 43 (32%) cases of febrile neutropenia and 2 (1.5%) Grade III thrombocytopenia with 3 (2%) toxic deaths. Grade III gastrointestinal toxicity (diarrhea) occurred in 35 (26%) and cardiac toxicity (congestive cardiac failure) in 2 (1.5%) patients. On univariate analysis, none of the variables (baseline serum albumin, hemoglobin, disease stage, or age) was found significant for chemotoxicity. At a median follow-up of 27 months (0.13–71.30 months), the estimated median disease-free survival (DFS) was 52 months in locally advanced group; however, the early breast cancer cohort has not reached to median DFS. Conclusions: TAC is an effective regimen but has significant toxicity despite the use of primary prophylactic Granulocyte Colony-Stimulating-Factor (G-GSF), including a small possibility of death. It can be considered “practically feasible” regimen in the adjuvant setting in carefully selected, fit patients.

Abstract
BACKGROUND Cisplatin and 5 fluorouracil drug combination is inferior to the combination of taxane with these 2 drugs. However, often in clinical practice at our center giving TPF (docetaxel, cisplatin, 5 fluorouracil) is difficult in view of logistics and tolerance issues. In such a scenario, we prefer to use the 2 drugs combination of platinum and taxane. However, no study has addressed whether a 2 drugs combination, which includes taxane is inferior to the 3 drugs combination and which the taxane of choice is in the 2 drugs combination of taxane and platinum. METHODS This is a retrospective analysis of prospectively collected data of patients undergoing induction chemotherapy (IC) in oral cavity cancers from 2010 to 2012. We chose for analysis those patients who had a baseline scan done within 4 weeks of starting therapy and a follow-up scan done within 2 weeks of completion of the second cycle of IC. Response was scored in accordance with RECIST version 1.1. Chi-square analysis was done to compare response rates (RRs) between regimens. RESULTS Two hundred and forty-five patients were identified. The median age was 45 years (24-70 years), 208 (84.9%) were male patients, and 154 patients (62.9%) had primary in the Buccal mucosa. The regimens received were TPF 22 (9%), docetaxel + cisplatin 97 (39.6%), paclitaxel + cisplatin 89 (36.3%), docetaxel + carboplatin 16 (6.5%) and paclitaxel + carboplatin 21 (8.6%). The overall RRs were complete response, partial response, stable disease and progressive disease in 4 (1.6%), 56 (22.9%), 145 (59.2%) and 40 (16.3%). The 3 drugs regimen (TPF) had 50% RR as compared to 22% RR with 2 drugs regimen (P = 0.004). Docetaxel containing regimens had 30.3% RR as compared to 17.2% RR with paclitaxel containing regimens (P = 0.094). CONCLUSIONS TPF has better RR than a 2 drugs taxane-containing regimen and docetaxel leads to a better RR than paclitaxel for IC in locally advanced oral cavity cancers.

Abstract
The 5th Biennial Metronomic and Anti-angiogenic Therapy Meeting was held on 6th – 8th May in the Indian city of Mumbai. The meeting brought together a wide range of clinicians and researchers interested in metronomic chemotherapy, anti-angiogenics, drug repurposing and combinations thereof. Clinical experiences, including many from India, were reported and discussed in three symposia covering breast cancer, head and neck cancers and paediatrics. On the pre-clinical side research into putative mechanisms of action, and the interactions between low dose metronomic chemotherapy and angiogenesis and immune responses, were discussed in a number of presentations. Drug repurposing was discussed both in terms of clinical results, particularly with respect to angiosarcoma and high-risk neuroblastoma, and in pre-clinical settings, particularly the potential for peri-operative interventions. However, it was clear that there remain a number of key areas of challenge, particularly in terms of definitions, perceptions in the wider oncological community, mechanisms of action and predictive biomarkers. While the potential for metronomics and drug repurposing in low and middle income countries remains a key theme, it is clear that there is also considerable potential for clinically relevant improvements in patient outcomes even in high income economies.

Abstract
Denervation is a well recognized procedure to treat degenerative or posttraumatic joint conditions, especially in cases where pain is a significant impediment to function even in the presence of stable and supple joint. However, this procedure currently is not as widely used for wrist surgeries as it merits. Denervation procedure obeys all-or-none phenomenon and we believe that even a few residual intact sensory fibers are able to transmit severe pain sensation and therefore every attempt should be made to target all the sensory supply to the wrist joint. In the present article a modified and radical technique using a single dorsal incision is proposed to address the hypothetical pitfalls of leaving undivided sensitive branches. Preliminary results of 21 cases operated on by this method are presented.

Abstract
Introduction Epidermal growth factor receptor (EGFR) mutations in non–small-cell lung cancers (NSCLC) may be more common in patients with brain metastases. Previous studies, however, did not adjust for effects of confounding variables. Methods This retrospective study included 1,522 consecutive patients with NSCLC, whose tumors were diagnosed and tested for EGFR mutations at the University of Nebraska Medical Center (Omaha, NE) and Tata Memorial Hospital (Mumbai, India). Multivariate logistic regression was used to identify any association between EGFR status and clinical factors. Results EGFR mutations were more common in females than males (38.7% v 24.8%), Asians than whites (31.3% v 13.4%), nonsmokers than smokers (40.2% v 14.6%), alcohol nonconsumers than users (32.4% v 15.8%), adenocarcinoma than other histology types (32.7% v 10.3%), and patients with brain metastases than extracranial or no metastases (39.4% v 29.8% v 15.1%; P < .001 for all comparisons). There was a higher likelihood of an EGFR mutation among patients with brain metastases (odds ratio, 1.8; P < .001). The median overall survival (OS) was 19.8 months. Patients with brain metastases had a shorter median OS (15 v 20.6 months; P = .02). However, in the cohort of EGFR mutation–positive patients, there was no difference in median OS between patients with and without brain metastases (20.8 v 25.1 months; P = .11). Conclusion There is a nearly two-fold higher incidence of EGFR mutations in NSCLC among patients with brain metastases at diagnosis. EGFR mutations did not predict for outcomes from brain metastases.

Abstract
BACKGROUND Oral cavity cancer is the most common cancer among rural India. There is a paucity of data for outcomes of operable oral cavity cancer from rural India. Use of maintenance metronomic may delay or avoid relapse. AIM To evaluate outcomes of operable oral cavity carcinoma and evaluate impact of maintenance metronomic chemotherapy. OBJECTIVES To evaluate disease-free survival (DFS), overall survival (OS), and factors affecting the outcome in operable oral cavity cancer. MATERIALS AND METHODS Data of patients diagnosed with oral cavity cancer registered between May 2008 and May 2014 were retrieved. Only those patients with operable oral cavity cancer and upfront definitive surgery were included in the study. Demographic profile, stage, tobacco consumption, adjuvant therapy, and pattern of failure were collected. Kaplan-Meir survival analysis was used to determine DFS and OS. Log-rank test was used to evaluate factors affecting outcome. RESULTS Median follow-up is 24 months. Out of 335 patients, 225 (67%) had advanced operable cancer with 42/225 (18%) and 183/225 (82%) as Stages III and IVA, respectively. Buccal mucosa was the most common subsite (178/335, 53%) followed by tongue (63/335, 19%). Ninety-two percent patients were addicted to smokeless tobacco, whereas 27% were smokers. Median DFS is 13 months with 2 years relative DFS 32%. Median OS is 30 months, with 2 years OS of 54%. Metronomic adjuvant oral chemotherapy was given in 130/225 (58%); Stage III and IVA patients with median of 14 months (3-18 months). Use of metronomic chemotherapy improved DFS (8 vs. 14 months, P = 0.22) and OS (14 vs. 26 months, P = 0.04). CONCLUSION Oral cavity cancer is a major health care problem in rural India. Presentation at advanced stage leads to suboptimal outcomes. Benefit of metronomic maintenance chemotherapy in locally advanced oral cavity needs to be further evaluated prospectively.

Abstract
Background: Carcinoma of external auditory canal (EAC) is a very rare malignancy with surgical resection as the main modality of treatment. The outcomes with nonsurgical modalities are very dismal. We present a retrospective analysis of 4 patients evaluating the role of neoadjuvant chemotherapy in technically unresectable cancers. Materials and Methods: This is a retrospective analysis of 4 patients from our institute from 2010 to 2014 with carcinoma EAC who were deemed unfit for surgery due to extensive disease involving occipital bone with soft tissue infiltration (n = 2), temporal dura (n = 1), left temporal lobe, and extensive soft tissue involvement (n = 1). All these patients received neoadjuvant chemotherapy with docetaxel, cisplatin and 5 fluorouracil (n = 3) and paclitaxel and cisplatin (n = 1). Results: Response evaluation showed a partial response (PR) in 3 and stable disease (SD) in 1 patient by Response Evaluation Criteria in Solid Tumors criteria. All 3 patients who received 3 drug chemotherapy had PR while 1 patient who received 2 drug chemotherapy had SD. Two of these patients underwent surgery, and other 2 underwent definitive chemoradiation. One of 3 patients who achieved PR underwent surgical resection; the other 2 remained unresectable in view of the persistent intradural extension and infratemporal fossa involvement. One patient who had SD could undergo surgery in view of clearance of infraatemporal fossa. Recent follow-up shows that 3 out of these 4 patients are alive. Conclusion: This indicates that there may be a role of induction chemotherapy in converting potentially unresectable tumors to resectable disease that could produce better outcomes in carcinoma EAC.

Abstract
Ultrasonography(US) of the scrotum has been demonstrated to be useful in the diagnosis of fluid in the scrotal sac. Grayscale US characterizes the lesions as testicular or extratesticular and, with color Doppler, power Doppler and pulse Doppler, any perfusion can also be assessed. Cystic or encapsulated fluid collections are relatively common benign lesions that usually present as palpable testicular lumps. Most cysts arise in the epidydimis, but all anatomical structures of the scrotum can be the site of their origin. US may suggest a specific diagnosis for a wide variety of intrascrotal cystic and fluid lesions and appropriately guide therapeutic options. The paper reviews the current knowledge of ultrasound in conditions with fluid in the testis and scrotum. The review presents the applications of ultrasonography in the diagnosis of hydrocele, testicular cysts, epididymal cysts, spermatoceles, tubular ectasia, hernia and hematoceles. The aim of this paper is to provide a pictorial review of the common and uncommon presentation of fluid within the scrotal spaces.

Abstract
Cytotoxic antiproliferative chemotherapeutic agents are the mainstay of treatment in cancers. Chemotherapy is usually administered every 2-3 weeks. Along with acute toxicity and long-term effects of cumulative doses, this strategy potentially allows regrowth of the tumor in the interval period and leads to the emergence of resistant populations of tumor cells. Moreover, even with intense chemotherapy, the outcome is stagnating for most of the tumors. There has been recent interest in the use of chemotherapy in fractionated doses which is far below the maximum tolerated dose. This is called metronomic scheduling of chemotherapy. Here, we review the biology and evidence for metronomic chemotherapy.

Abstract
BACKGROUND Cluster analyses have enhanced understanding of the heterogeneity of both paediatric and adult wheezing. However, while adolescence represents an important transitional phase, the nature of young adult wheeze has yet to be clearly characterised. OBJECTIVES To use cluster analysis to define, for the first time, clinically relevant young adult wheeze clusters in a longitudinal birth cohort. METHODS K-means cluster analysis was undertaken among 309 currently wheezing subjects at 18 years in the Isle of Wight birth cohort (N = 1456). Thirteen disease-characterising clustering variables at 18 years were used. Resulting clusters were then further characterised by severity indices plus potential risk factors for wheeze development throughout the 1st 18 years of life. RESULTS Six wheeze clusters were identified. Cluster 1 (12.3%) male-early-childhood-onset-atopic-wheeze-with-normal-lung-function had male predominance, normal spirometry, low bronchodilator reversibility (BDR), intermediate bronchial hyper-responsiveness (BHR), high atopy prevalence and more admissions. Cluster 2 (24.2%) early-childhood-onset-wheeze-with-intermediate-lung-function had no specific sex association, intermediate spirometry, BDR, BHR, more significant BTS step therapy and admissions. Cluster 3 (9.7%) female-early-childhood-onset-atopic-wheeze-with-impaired-lung-function showed female predominance, high allergic disease comorbidity, more severe BDR and BHR, greatest airflow obstruction, high smoking prevalence, higher symptom severity and admissions. Cluster 4 (19.4%) female-undiagnosed-wheezers had adolescent-onset non-atopic wheeze, low BDR and BHR, impaired but non-obstructed spirometry, high symptom frequency and highest smoking prevalence. Cluster 5 (24.6%) female-late-childhood-onset-wheeze-with-normal-lung-function showed no specific atopy association, normal spirometry, low BDR, BHR and symptom severity. Cluster 6 (9.7%) male-late-childhood-onset-atopic-wheeze-with-impaired-lung-function had high atopy and rhinitis prevalence, increased BDR and BHR, moderately impaired spirometry, high symptom severity and higher BTS step therapy. CONCLUSIONS AND CLINICAL RELEVANCE Young adult wheeze is diverse and can be classified into distinct clusters. More severe clusters merit attention and are associated with childhood onset, atopy, impaired lung function and in some, smoking. Smoking-associated undiagnosed wheezers also merit recognition. Better understanding of young adult wheeze could facilitate better later adult respiratory health.

Abstract
An electronically active and spectral sensitive fluorescent "turn-on" chemosensor (BTP-1) based on the benzo-thiazolo-pyrimidine unit was designed and synthesized for the highly selective and sensitive detection of Fe(3+) from aqueous medium. With Fe(3+), the sensor BTP-1 showed a remarkable fluorescence enhancement at 554 nm (λex = 314 nm) due to the inhibition of photo-induced electron transfer. The sensor formed a host-guest complex in 1:1 stoichiometry with the detection limit down to 0.74 nM. Further, the sensor was successfully utilized for the qualitative and quantitative intracellular detection of Fe(3+) in two liver cell lines i.e., HepG2 cells (human hepatocellular liver carcinoma cell line) and HL-7701 cells (human normal liver cell line) by a confocal imaging technique.

Abstract
CONTEXT Critically ill patients requiring mechanical ventilation frequently need sedatives and analgesics to facilitate their care. Dexmedetomidine, a short-acting alpha-2-agonist, possesses anxiolytic, anesthetic, hypnotic, and analgesic properties. AIMS The objective of this study was to evaluate the efficacy and safety of dexmedetomidine in comparison to propofol in the management of sedation for post-operative intensive care unit (ICU) patients, as a sedative agent. SETTINGS AND DESIGN Teaching hospital, A phase III, prospective, open, randomized and comparative. MATERIALS AND METHODS Thirty patients who were ambulatory and who required the post-operative mechanical ventilation or post-operative sedation were enrolled, in which 15 patients received Dexmedetomidine and remaining 15 patients received propofol. All these patients were treated for the period of 8 to 24 h. STATISTICAL ANALYSIS USED Data were analyzed using Student's t-test and Chi-square test. The value of P < 0.05 was considered as statistically significant. RESULTS Demographic data were comparable. Pulse rate, respiratory rate and blood pressure were comparable. Depth of sedation and extubation time were similar. To maintain analgesia throughout the study period, patients receiving propofol infusions required significantly more analgesics than patients receiving Dexmedetomidine. CONCLUSIONS Dexmedetomidine appears to be a safe and acceptable ICU sedative agent when both the clinician's and patient's perspectives are considered.
