[PMID: 26144319 DOI: 10.1016/j.clon.2015.06.014] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/10/2015] [Revised: 05/28/2015] [Accepted: 06/12/2015] [Indexed: 10/23/2022]
Abstract
AIMS To compare the inter-fraction dose variation for bladder and rectum using a bladder-rectum spacer balloon (BRSB) versus vaginal gauze packing (VGP) in patients treated with high dose rate intracavitary brachytherapy for carcinoma cervix. MATERIALS AND METHODS After the completion of external radiotherapy, 80 patients were randomised to receive intracavitary brachytherapy using either the BRSB or VGP. The procedure was carried out under general anaesthesia using tandem ovoid applicators. Computed tomography-based planning was carried out and the dose was prescribed to point A. Doses to 0.1, 1 and 2 cm(3) volumes were reported for bladder and rectum for each fraction. The absolute inter-fraction dose variation for each subvolume was compared using the independent sample t-test. RESULT The mean bladder and rectal volumes, as well as the inter-fraction volume variation, were comparable for the BRSB and VGP. The BRSB resulted in a significant reduction in absolute dose as well as the inter-fraction variation for dose to 2 cm(3) rectum volumes (BRSB 0.80 Gy, standard deviation 0.71 Gy versus VGP 1.16 Gy, standard deviation 0.83 Gy; P = 0.04). Cumulative bladder D2cm(3) doses of more than 90 Gy3 were observed in six patients in the BRSB arm versus four patients in the VGP arm (P = 0.73). In both the arms, the rectal D2cm(3) doses did not exceed 75 Gy3. CONCLUSIONS Use of a BRSB resulted in a significant reduction in inter-fraction variation in D2cm(3) rectal dose. However, no significant difference in the inter-fraction dose variation for the other subvolumes of bladder and rectum could be shown between the BRSB and VGP. The use of a BRSB may enable rectal dose reduction and inter-fraction variation where anaesthesia is not routinely used or where there is limited physician expertise. The modification suggested in the BRSB may facilitate its additional usage.

Abstract
BACKGROUND Pancreatic cancer has an extremely poor prognosis and prolonged survival is achieved only by resection with macroscopic tumor clearance. There is a strong rationale for a neoadjuvant approach, since a relevant percentage of pancreatic cancer patients present with non-metastatic but locally advanced disease. The objective of the present study was to assess the effect of neoadjuvant chemoradiation therapy (NACRT) on tumor response, down staging and resection, toxicity and any survival advantage. MATERIALS AND METHODS A prospective pilot study was carried out from January 2009 to June 2011 in which 15 patients of locally advanced unresectable pancreatic cancer were included. All patients were treated with NACRT protocol with oral Capecitabine and 3D conformal radiotherapy (3DCRT) of 30 Gy in 10 fractions. The patients were restaged 3 to 4 weeks after the completion of NACRT and explored for resection. RESULTS Out of 15 patients, fourteen were evaluable. Four patients underwent surgery, 5 had partial response but remained unresectable, 2 patients had stable disease and 3 had progressive disease. Most of the toxicities were slight and were in grade 1 to 2. None of the patients developed grade 3 or 4 gastrointestinal or hematological toxicity. The median survival was 15 months for resected patients and 8.6 months for unresected patients, respectively. The 2 year actuarial overall survival was 34.6%. CONCLUSION All patients with locally unresectable pancreatic cancer should be offered chemoradiation therapy, in hopes of down staging the tumor for possible resection and achieving higher survival.

Abstract
CONTEXT Cancer data from Rajasthan is limited. Only three studies, one from Western Rajasthan, and the other two from Eastern Rajasthan have been published previously. AIMS To find out the spectrum of malignant neoplasms in Jaipur region by studying the proportion and site wise distribution of malignancy cases reported at five major hospitals and pathology centers in Jaipur region. SETTINGS AND DESIGN A retrospective analysis of histopathology records of 5 years (2004-2008) was done. Approximately 200,000 histopathology and cytology reports were analyzed and 34,486 new cancer cases were identified. STATISTICAL ANALYSIS USED Percentages and proportions. RESULTS A total of 34,486 new cases of cancers were recorded in five years. There were 58.58% (20202) males and 41.42% (14284) females, with the male to female ratio being 1.41:1. Organ wise, Lung (13.25%), Larynx (5.35%), Oropharynx (5.09%), Brain (4.84%), Tongue (4.62%) and Prostate (4%) were the most common sites involved in males, whereas Breast (25.6%), Cervix (10.26%), Ovary (5.4%), Brain (3.68%), Esophagus (3.4%), Lung (3.01%) and Gall Bladder (2.35%) were common sites for malignancies in females. CONCLUSIONS Significant findings were, a higher frequency of tobacco related cancers i.e., Lung cancer and Head and neck cancer in males, and screening detectable cancers (Breast and Cervix) in females. A higher frequency of Lung cancer in females was also noted as compared to previous studies. An unusually high frequency of Gall Bladder Cancers especially among the female population in this region is also a cause of concern. Our data was compared with the national data.

Abstract
BACKGROUND & OBJECTIVES The characteristics of prostate specific antigen (PSA) for trans-rectal ultrasonography guided prostate biopsy in men with lower urinary tract symptoms (LUTS) are not well defined. This study was carried out to analyse the threshold of PSA for biopsy in symptomatic men in India. METHODS From January 2000 to June 2011, consecutive patients who had digital rectal examination (DRE) and PSA testing done for LUTS were included in this study. PSA was done with ELISA technique. Patients with acute or chronic prostatitis, prostatic abscess, history of surgery on prostate within the previous three months and patients on 5α-reductase inhibitors or on urethral catheter were excluded. RESULTS Of the 4702 patients evaluated, 70.9 per cent had PSA of less than 4 ng/ml and 29.1 per cent had PSA of more than 4 ng/ml. Of these, 875 men with a mean age of 65.72±7.4 (range 50-75 yr) had trans rectal ultrasonography (TRUS) guided biopsy. Twenty five men had biopsy at PSA level of <4 ng/ml due to positive DRE, 263 at 4.1-10ng/ml, 156 at 10.1-20 ng/ml and 431 at >20 ng/ml. Positive predictive value of PSA in ranges of 4.1-10, 10.1-20, >20 ng/ml was 15.2, 24 and 62.6 per cent, respectively with negative DRE. PSA cut-off to do biopsy was derived by ROC curve as 5.82 ng/ml for all the men. When the subjects were further stratified on the basis of DRE findings, a cut-off of 5.4 ng/ml was derived in men with normal DRE. INTERPRETATION & CONCLUSIONS A cut-off for biopsy in symptomatic men with negative DRE could safely be raised to 5.4 ng/ml, which could avoid subjecting 10 per cent of men to undergo unnecessary biopsy.

Abstract
OBJECTIVE To assess the incidence and review the probable etiologies of port site recurrence in patients undergoing laparoscopic radical nephrectomy. MATERIALS AND METHODS One hundred thirty-six patients undergoing laparoscopic surgeries for renal malignancy, including 133 radical nephrectomies and 3 partial nephrectomies, from December 1999 to December 2008 at our institution were followed up for a median period of 59 months (12-120 months). Of the procedures, 121 were performed by transperitoneal, 5 by retroperitoneal and 10 by combined approach (retroperitoneal renal artery clipping followed by transperitoneal nephrectomy). Formal lymphadenectomy was not performed. Postoperative surveillance after radical nephrectomy included history and physical examination with blood tests 3-6 monthly, chest X-ray yearly and abdominal contrast-enhanced computed tomography (CECT) 1-2 yearly. The development of port site recurrence was diagnosed by physical examination, CECT and pathological findings. RESULTS Conversion to open surgery was done in 33 patients. Two (1.47% overall) port site recurrences were observed, both after radical nephrectomies done for renal masses with clinical stages T2N0M0 and TIN0M0. The pathological staging in the two were T2N1M0 Fuhrman's Grade III and T3aN1M0 Grade III, respectively. CONCLUSION Our results report that laparoscopic approach does not necessarily increase the risk of port site recurrence, provided the cases are carefully chosen, principles of oncologic surgery are followed, and conditions that increase the risk of port site metastasis are avoided.

Abstract
Aims: Dosimeteric and radiobiological comparison of two radiation schedules in localized carcinoma prostate: Standard Three-Dimensional Conformal Radiotherapy (3DCRT) followed by Intensity Modulated Radiotherapy (IMRT) boost (sequential-IMRT) with Simultaneous Integrated Boost IMRT (SIB-IMRT). Material and Methods: Thirty patients were enrolled. In all, the target consisted of PTV P + SV (Prostate and seminal vesicles) and PTV LN (lymph nodes) where PTV refers to planning target volume and the critical structures included: bladder, rectum and small bowel. All patients were treated with sequential-IMRT plan, but for dosimetric comparison, SIB-IMRT plan was also created. The prescription dose to PTV P + SV was 74 Gy in both strategies but with different dose per fraction, however, the dose to PTV LN was 50 Gy delivered in 25 fractions over 5 weeks for sequential-IMRT and 54 Gy delivered in 27 fractions over 5.5 weeks for SIB-IMRT. The treatment plans were compared in terms of dose–volume histograms. Also, Tumor Control Probability (TCP) and Normal Tissue Complication Probability (NTCP) obtained with the two plans were compared. Results: The volume of rectum receiving 70 Gy or more (V > 70 Gy) was reduced to 18.23% with SIB-IMRT from 22.81% with sequential-IMRT. SIB-IMRT reduced the mean doses to both bladder and rectum by 13% and 17%, respectively, as compared to sequential-IMRT. NTCP of 0.86 ± 0.75% and 0.01 ± 0.02% for the bladder, 5.87 ± 2.58% and 4.31 ± 2.61% for the rectum and 8.83 ± 7.08% and 8.25 ± 7.98% for the bowel was seen with sequential-IMRT and SIB-IMRT plans respectively. Conclusions: For equal PTV coverage, SIB-IMRT markedly reduced doses to critical structures, therefore should be considered as the strategy for dose escalation. SIB-IMRT achieves lesser NTCP than sequential-IMRT.

Abstract
Disrupted thyroid hormone function evokes severe physiological consequences in the immature brain. In adulthood, although clinical reports document an effect of thyroid hormone status on mood and cognition, the molecular and cellular changes underlying these behavioural effects are poorly understood. More recently, the subtle effects of thyroid hormone on structural plasticity in the mature brain, in particular on adult hippocampal neurogenesis, have come to be appreciated. However, the specific stages of adult hippocampal progenitor development that are sensitive to thyroid hormone are not defined. Using nestin-green fluorescent protein reporter mice, we demonstrate that thyroid hormone mediates its effects on hippocampal neurogenesis by influencing Type 2b and Type 3 progenitors, although it does not alter proliferation of either the Type 1 quiescent progenitor or the Type 2a amplifying neural progenitor. Thyroid hormone increases the number of doublecortin (DCX)-positive Type 3 progenitors, and accelerates neuronal differentiation into both DCX-positive immature neurones and neuronal nuclei-positive granule cell neurones. Furthermore, we show that this increase in neuronal differentiation is accompanied by a significant induction of specific transcription factors involved in hippocampal progenitor differentiation. In vitro studies using the neurosphere assay support a direct effect of thyroid hormone on progenitor development because neurospheres treated with thyroid hormone are shifted to a more differentiated state. Taken together, our results indicate that thyroid hormone mediates its neurogenic effects via targeting Type 2b and Type 3 hippocampal progenitors, and suggests a role for proneural transcription factors in contributing to the effects of thyroid hormone on neuronal differentiation of adult hippocampal progenitors.

Abstract
BACKGROUND R(2)' is an MRI measure of microscopic magnetic field inhomogeneity, and is increased by the paramagnetic effect of iron and the diamagnetic effect of myelin. R(2)' may detect features of multiple sclerosis (MS) not evident with conventional MRI. METHODS Multiecho T(2) and T(2)* weighted sequences were obtained from 21 healthy controls (nine men, 12 women; mean age 36 years) and 28 MS patients (seven men, 21 women; 18 relapsing remitting, 10 secondary progressive; mean age 42 years). T(2) and T(2)* relaxation time maps were created from the multiecho sequences, and R(2)' maps were created using the formula R(2)' = R(2)*-R(2) = 1/T(2)*-1/T(2). R(2)' was measured in MS white matter lesions and in regions of interest in normal appearing white matter (NAWM) and grey matter in all subjects. RESULTS R(2)' was reduced in NAWM in MS compared with controls (9.5/s vs 10.1/s, p=0.05). R(2)' was additionally reduced in lesions, both T(1) isointense (8.5/s vs 9.5/s, p=0.02) and T(1) hypointense (7.7/s vs 9.5/s, p=0.003) compared with NAWM. R(2)' tended to be higher in the basal ganglia of MS patients compared with controls, and was significantly higher in the caudate nucleus in secondary progressive MS (12.9/s vs 10.9/s, p=0.03). Increased T(2) lesion volume predicted an increase in R(2)' in the caudate (β=0.412, p=0.02). CONCLUSIONS Reduction in R(2)' in NAWM and lesions is consistent with a decreases in myelin, tissue iron and/or deoxyhaemoglobin. Increased caudate R(2)' in patients with secondary progressive MS is consistent with increased iron deposition, as corroborated by other techniques.

Abstract
PURPOSE To demonstrate a Web-based electronic peer review system that has the potential to improve quality of care for radiation therapy patients. The system provides tools that allow radiation oncologists to seek peer review of target and critical structure delineation, treatment plans, and share clinical data with peers to optimize radiation therapy treatments. MATERIAL AND METHODS Peer review of radiation therapy treatment planning data prior to its initiation improves the quality of radiation therapy and clinical outcomes. Web-based access to radiation therapy treatment planning data and medical records mitigate existing geographical and temporal constraints. With internet access, the healthcare provider can access the data from any location and review it in an interactive and collaborative manner. Interoperability standard like DICOM-RT and IHE-RO compliant RT Systems have facilitated the design and implementation of PRS with Silverlight Web technology, .net Framework and SQL Server. Local DICOM-RT archive and cloud based services are deployed to facilitate remote peer reviews. RESULTS To validate the PRS system, we tested the system for 100 patients with Philips Pinnacle v 9.0 and Varian Eclipse v 8.9 treatment planning system (TPS). We transmitted the DICOM RT data from the TPS to the cloud based services via the PRS local DICOM RT Archive. Various CT simulation based parameters such as orientation of CT, properties of RT structures etc. were compared between the TPS and PRS system. Data integrity of other parameters such as patient demographics (patient name, ID, attending physician etc.) and dose volume related parameters were also evaluated. Such rigorous testing allowed us to optimize the functionalities and clinical implementation of the PRS. CONCLUSIONS We believe that the PRS will improve the quality and safety of a broad spectrum of radiation therapy patients treated in underserved areas while discouraging the overutilization of expensive radiation treatment modalities. This research and development project is supported by the James and Ester King Biomedical Research Program grant # RC1-09KW-09-26829.

Abstract
Sodium blockade with lamotrigine is neuroprotective in animal models of central nervous system demyelination. This study evaluated the effect of lamotrigine on magnetisation transfer ratio (MTR), a putative magnetic resonance imaging measure of intact brain tissue, in a group of subjects with secondary progressive multiple sclerosis (MS). In addition, the utility of MTR measures for detecting change in clinically relevant pathology was evaluated. One hundred seventeen people attending the National Hospital for Neurology and Neurosurgery or the Royal Free Hospital, London, UK, were recruited into a double-blind, parallel-group trial. Subjects were randomly assigned by minimisation to receive lamotrigine (target dose 400 mg/day) or placebo for 2 years. Treating and assessing physicians and patients were masked to treatment allocation. Results of the primary endpoint, central cerebral volume, have been published elsewhere. Significant differences between the verum and placebo arms were seen in only two measures [normal appearing grey matter (NAGM) p = 0.036 and lesion peak height (PH) p = 0.004], and in both cases there was a greater reduction in MTR in the verum arm. Significant correlations were found of change in MS functional composite with all MTR measures except lesion and normal appearing white matter (NAWM) PH. However, the change in MTR measures over 2 years were small, with only NAGM mean (p = 0.001), lesion peak location (p = 0.11) and mean (p < 0.0001) changing significantly from baseline. These data did not show that lamotrigine was neuroprotective. The clinical correlation of MTR measures was consistent, but the responsiveness to change was limited.

Abstract
The occurrence of multiple primary malignant neoplasias (MPMN) is a rare but increasingly frequently reported event. Many theories have been proposed to explain MPMNs, but none have been proven. The key risk factors appear to be smoking and family history. While numerous studies have been published on the development of second malignancies following a first primary, the literature contains only few case reports and reviews of patients with three or more malignancies. We report a case of a young female who, over a period of 30 years, developed four different malignancies and was treated radically on each occasion.

Abstract
Transcriptional activity of the vitamin D receptor (VDR) gene is regulated by androgen receptor (AR) gene and both are associated with renal stone formation. We examined gene polymorphisms of VDR (PCR-RFLP) and AR (GeneScan analysis) in 125 stone formers and 150 controls from north India. Genotype Ff of Fok-I and Tt of Taq-I demonstrated significantly higher risk (P<0.001, OR=3.559 and P=0.019, 1.830 respectively). Variant f allele exhibited 1.7-folds higher risk. Ff of Fok-I and Aa of Apa-I gene polymorphism showed higher risk in males only. Mean CAG repeat was significantly higher in hypercalciuric patients as compared to normocalciuric (mean=21.62 ± 3.384 vs. 20.11 ± 3.182; P=0.034). Combined effects 1.8-folds higher risk in patients with Tt genotype of Taq-I and short CAG repeat. Thus, association of FokI and TaqI VDR gene polymorphisms suggest VDR as an important genetic marker for urolithiasis. Further, patients with combination of Tt of Taq-I and short CAG repeat were at higher risk for stone formation.

Abstract
INTRODUCTION Asthma prevalence is increasing in developing countries such as India. Little is known on parental knowledge of asthma severity, management and psychosocial impact, particularly among rural dwellers. Further, it is not known whether the female asthmatic child is particularly vulnerable. OBJECTIVE To evaluate parental asthma knowledge and psychological impact of having an asthmatic child. METHODS 134 consecutive caregivers were surveyed at the visit for their child's asthma exacerbation at an urban hospital in Kanpur, India between 3/2007-3/2008. RESULTS The child's age range was 5.7A +/- 2.7 years. 76% were urban city dwellers with significantly higher number having a college degree. 23% children had moderate to severe persistent asthma; however, only 42% were on inhaled steroids. Parental severity perception was comparable to National Heart, Lung and Blood Institute (NHLBI) classification. While 67% identified bronchoconstriction occurred with asthma, only 8.9% recognized that inflammation played a role. There was no difference in the perceived stress by area of residence with 89% reported not or only sometimes feeling stressed with having an asthmatic child. Similarly, the concern among those with a female asthmatic child did not differ with 73% of caregivers believing that asthma would not affect their daughter's future. CONCLUSION In an urban Indian hospital, 23% of asthmatic children had moderate to severe persistent asthma but only 9% were on controllers. Their parents were well educated, able to identify asthma severity appropriately and denied being stressed with having asthmatic children, irrespective of the gender of the child. However, their understanding of asthma pathophysiology was sub-optimal. Increased disease knowledge may lead to greater medication adherence among asthmatic children in India.

Abstract
BACKGROUND There is considerable interest in tissue-protective treatments for multiple sclerosis (MS). METHODS AND OBJECTIVES We convened a group of MS clinical trialists and related researchers to discuss designs for proof of concept studies utilizing currently available data and assessment methods. RESULTS Our favored design was a randomized, double-blind, parallel-group study of active treatment versus placebo focusing on changes in brain volume from a post-baseline scan (3-6 months after starting treatment) to the final visit 1 year later. Study designs aimed at reducing residual deficits following acute exacerbations are less straightforward, depending greatly on the anticipated rapidity of treatment effect onset. CONCLUSIONS The next step would be to perform one or more studies of potential tissue-protective agents with these designs in mind, creating the longitudinal data necessary to refine endpoint selection, eligibility criteria, and sample size estimates for future trials.

Abstract
Hemangiopericytoma, a rare mesenchymal tumour, is believed to originate from the pericyte of Zimmermann. It may affect every organ in the body. Recurrences after treatment and metastasis are well known. However, presentation of hemangiopericytoma with peritoneal carcinomatosis is not documented in literature. To the best our knowledge, we report the imaging findings of the first histologically proven case of hemangiopericytoma with peritoneal carcinomatosis.
