Abstract
BACKGROUND Cicer microphyllum Benth. is a crop wild relative (CWR) of chickpea (C. arietinum L.), that possess useful genes for cold and drought tolerance. The species is being conserved in the In Vitro Active Genebank for short- to medium-term conservation. Cryopreservation would be a useful complementary approach for its long-term conservation. OBJECTIVE The current work aimed to develop an efficient cryoconservation protocol for cryobanking of C. microphyllum shoot tips. MATERIALS AND METHODS In vitro shoot tips excised from 4-month old shoot cultures grown on B5 + 0.5 mg/L KIN + 0.1 mg/L NAA + 10 mg/L AgNO3 medium were cryoconserved using a droplet-vitrification technique. Post-thaw regrowth was evaluated after: (i) preculture medium (B5 basal, B5 + 3, 4, 6 and 10% sucrose), (ii) preculture incubation temperature (25 ± 2, 10, 8 and 22/5 degree C), (iii) PVS2 duration (10, 20, 30. 40, 50 and 60 min) and (iv) regrowth medium (B5) supplemented with 0.5 mg/L KIN + 0.1 NAA mg/L; 0.5 mg/L KIN + 0.1 mg/L NAA + 10 mg/L AgNO3; 0.2 mg/L BAP + 10 mg/L AgNO3; 0.2 mg/L BAP + 20 mg/L AgNO3 and 0.2 mg/L BAP + 30 mg/L AgNO3. RESULTS In vitro shoot tips grown on B5 + 0.5 mg/L KIN + 0.1 mg/L NAA + 10 mg/L AgNO3, precultured on B5 + 6% sucrose at 10 degree C for 3 days, followed by PVS2 treatment for 20 min, unloading solution for 60 min and regrowth on B5 + 0.2 mg/L BAP + 20 mg/L AgNO3 resulted in highest survival (57%) and regrowth (40%) after cryoconservation. CONCLUSION The standardized protocol was successfully used for cryobanking of in vitro shoot tips of C. microphyllum in the In Vitro Base Genebank of ICAR-NBPGR, New Delhi.

Abstract
STUDY QUESTION What is the evidence to guide the management of women who wish to conceive following abdominopelvic radiotherapy (AP RT) or total body irradiation (TBI)? SUMMARY ANSWER Pregnancy is possible, even following higher doses of post-pubertal uterine radiation exposure; however, it is associated with adverse reproductive sequelae and pregnancies must be managed in a high-risk obstetric unit. WHAT IS KNOWN ALREADY In addition to primary ovarian insufficiency, female survivors who are treated with AP RT and TBI are at risk of damage to the uterus. This may impact on its function and manifest as adverse reproductive sequelae. STUDY DESIGN SIZE DURATION A review of the literature was carried out and a multidisciplinary working group provided expert opinion regarding assessment of the uterus and obstetric management. PARTICIPANTS/MATERIALS SETTING METHODS Reproductive outcomes for postpubertal women with uterine radiation exposure in the form of AP RT or TBI were reviewed. This included Pubmed listed peer-reviewed publications from 1990 to 2019, and limited to English language.. MAIN RESULTS AND THE ROLE OF CHANCE The prepubertal uterus is much more vulnerable to the effects of radiation than after puberty. Almost all available information about the impact of radiation on the uterus comes from studies of radiation exposure during childhood or adolescence.An uncomplicated pregnancy is possible, even with doses as high as 54 Gy. Therefore, tumour treatment doses alone cannot at present be used to accurately predict uterine damage. LIMITATIONS REASONS FOR CAUTION Much of the data cannot be readily extrapolated to adult women who have had uterine radiation and the publications concerning adult women treated with AP RT are largely limited to case reports. WIDER IMPLICATIONS OF THE FINDINGS This analysis offers clinical guidance and assists with patient counselling. It is important to include patients who have undergone AP RT or TBI in prospective studies to provide further evidence regarding uterine function, pregnancy outcomes and correlation of imaging with clinical outcomes. STUDY FUNDING/COMPETING INTERESTS This study received no funding and there are no conflicts of interest. TRIAL REGISTRATION NUMBER N/A.

Abstract
BACKGROUND Optimal initial management of rectal carcinoma with synchronous metastases (RCSM) is controversial - both for patients being treated with curative and palliative intent. This study aims to evaluate the use of an upfront treatment strategy combining FOLFOX chemotherapy with split-course pelvic chemoradiation (FOLFOX + CRT) for patients with RCSM. MATERIAL AND METHODS An analysis of all patients who commenced treatment with FOLFOX + CRT at our institutions between January 2009 and June 2014 was performed. The regimen consisted of a total of 12 weeks of treatment with split-course pelvic chemoradiation (50.4Gy with concurrent oxaliplatin and 5-FU) alternating with FOLFOX chemotherapy. Restaging imaging was performed following treatment, with subsequent management as per local standard of care. RESULTS 78 patients (15 with resectable liver-only metastases) were identified. 77 (99%) completed at least 45Gy of radiation and 87% completed ≥75% of planned dose intensity of both oxaliplatin and 5FU. Two (2.6%) patients died within 30 days of treatment. Rates of radiological complete or partial response for local and metastatic disease were 90% and 66%, respectively. 24% patients had radiological disease progression of metastatic disease. Median overall survival for patients with unresectable metastatic disease at baseline was 23 months (95%CI: 19-28). 12 patients underwent radical surgery to both the rectum and liver and had an estimated 3-year overall survival rate of 62% (95%CI: 37-100). For those patients who did not proceed to rectal surgery, only 7% required palliative re-irradiation or surgery at a later date and all >20months from initial treatment. CONCLUSIONS In patients with unresectable metastatic disease, FOLFOX + CRT provides durable pelvic control for the majority without the need for additional local treatment. For patients with an advanced primary tumor and synchronous resectable liver-only metastases, FOLFOX + CRT can be considered a feasible and tolerable upfront treatment option.

Abstract
Moisture stress is a major constraint in productivity across the wheat growing zones of India. Climate change and uneven rainfall further aggravate the situation under moisture stress environments. Wheat genotypes capable of giving increased yield under a broad range of optimal and sub-optimal water availability are considered desirable. This study was undertaken to evaluate various selection indices of moisture stress and their applicability in identifying drought tolerant wheat genotypes which can adapt to various moisture stressed environments in different wheat growing zones of India i.e., North Western Plain Zone, North Eastern Plain Zone, Central Zone and Peninsular Zone. A set of wheat genotypes were tested under moisture stress condition of different irrigation regimes. Irrigation treatments were arranged as main plots and varieties as sub plots. Fifteen wheat varieties representing major wheat growing zones of India were tested for water stress tolerance during two consecutive years. It was found that yield under irrigated conditions (Ypi), yield under stress conditions (Ysi) and lower stress tolerance index (STI), were marked indices for stress tolerance. Significantly positive correlation of Ypi and Ysi with STI, mean productivity (MP), geometric mean productivity (GMP) were obtained during both the years of the study. The indices of STI, MP and GMP could be used as the desirable indices for screening drought tolerant varieties. On the basis of findings of these indices wheat varieties NI-5439, WH-1021 and HD-2733 were found having higher stress tolerance and with better yield potential under both normal and restricted irrigation conditions of India.SAARC J.

Abstract
BACKGROUND Patients (pts) with metastatic rectal cancer and symptomatic primary, require local and systemic control. Chemotherapy used during chemoradiotherapy (CRT) is adequate for radiosensitisation, but suboptimal for systemic control. The aim of this phase II study was to assess tolerability, local/systemic benefits, of a novel regimen delivering interdigitating intensive chemotherapy with radical CRT. METHODS Eligible pts had untreated synchronous symptomatic primary/metastatic rectal cancer. A total of 12 weeks of treatment with split-course pelvic CRT (total 50.4 Gy with concurrent oxaliplatin and 5-FU infusion) alternating with FOLFOX chemotherapy. All pts staged with CT, MRI and FDG-PET pre and post treatment. RESULTS Twenty-six pts were treated. Rectal primary MRI stage: T3 81% and T4 15%. Liver metastases in 81%. Twenty-four pts (92%) completed the 12-week regimen. All patients received planned RT dose, and for both agents over 88% of patients achieved a relative dose intensity of >75%. Grade 3 toxicities: neutropenia 23%, diarrhoea 15%, and radiation skin reaction 12%. Grade 4 toxicity: neutropenia 15%. FDG-PET metabolic response rate for rectal primary 96%, and for metastatic disease 60%. CONCLUSIONS Delivery of interdigitating chemotherapy with radical CRT was feasible to treat both primary and metastatic rectal cancer. High completion and response rates were encouraging.

Abstract
Background: Preoperative radiotherapy (RT) is commonly used to treat localised soft-tissue sarcomas (STS). Hypoxia is an important determinant of radioresistance. Whether antiangiogenic therapy can ‘normalise' tumour vasculature, thereby improving oxygenation, remains unknown. Methods: Two cohorts were prospectively enrolled. Cohort A evaluated the implications of hypoxia in STS, using the hypoxic tracer 18F-azomycin arabinoside (FAZA-PET). In cohort B, sunitinib was added to preoperative RT in a dose-finding phase 1b/2 design. Results: In cohort A, 13 out of 23 tumours were hypoxic (FAZA-PET), correlating with metabolic activity (r2=0.85; P<0.001). Two-year progression-free (PFS) and overall (OS) survival were 61% (95% CI: 0.44–0.84) and 87% (95% CI: 0.74–1.00), respectively. Hypoxia was associated with radioresistance (P=0.012), higher local recurrence (Hazard ratio (HR): 10.2; P=0.02), PFS (HR: 8.4; P=0.02), and OS (HR: 41.4; P<0.04). In Cohort B, seven patients received sunitinib at dose level (DL): 0 (50 mg per day for 2 weeks before RT; 25 mg per day during RT) and two patients received DL: −1 (37.5 mg per day for entire period). Dose-limiting toxicities were observed in 4 out of 7 patients at DL 0 and 2 out of 2 patients at DL −1, resulting in premature study closure. Although there was no difference in PFS or OS, patients receiving sunitinib had higher local failure (HR: 8.1; P=0.004). Conclusion: In STS, hypoxia is associated with adverse outcomes. The combination of sunitinib with preoperative RT resulted in unacceptable toxicities, and higher local relapse rates.

Abstract
Sodium hypochlorite (NaOCl) is most commonly used as an irrigating solution in endodontic practice. This paper describes an incident of sodium hypochlorite extrusion past the apex (SHEPA) of the UR3. Management of the condition resulted in hospitalisation of the patient, and intravenous antibiotic and steroid therapy. This case report details the measures that can be employed to reduce the risk of SHEPA and management of its potentially serious complications. The reader should understand the various measures that can be adopted to reduce extrusion of endodontic irrigants beyond the root apex and management following SHEPA.

Abstract
OBJECTIVES The purpose of this study was to compare interfraction prostate displacement data between electronic portal imaging (EPI) and kilovoltage imaging (KVI) treatment units and discuss the impact of any difference on margin calculations for prostate cancer image-guided radiotherapy (IGRT). METHODS Prostate interfraction displacement data was collected prospectively for the first 4 fractions in 333 patients treated with IGRT with daily pre-treatment EPI or KVI orthogonal imaging. Displacement was recorded in the anteroposterior (AP), left-right (LR) and superoinferior (SI) directions. The proportion of displacement <3 mm and the difference in median absolute displacements were calculated in all directions. RESULTS 1088 image pairs were analysed in total, 448 by EPI and 640 by KVI. There were 23% (95% confidence interval [CI] 18-28%) more displacements under 3 mm for EPI than for KVI in the AP direction, 14% (95% CI 10-19%) more in the LR direction and 10% (95% CI 5-15%) more in the SI direction. The differences in absolute median displacement (KVI>EPI) were AP 1 mm, LR 1 mm and SI 0.5 mm. Wilcoxon rank-sum test showed that distributions were significantly different for all three dimensions (p<0.0001 for AP and LR and p=0.02 for SI). CONCLUSION EPI has a statistically significant smaller set-up error distribution than KVI. We would expect that, because fiducial marker imaging is less clear for EPI, the clinical target volume to planning target volume margin would be greater when using IGRT; however, relying wholly on displacement data gives the opposite result. We postulate that this is owing to observer bias, which is not accounted for in margin calculation formulas.

Abstract
This article explores the available strategies for protection against erosive toothwear. As part of a preventive regime, the importance of dietary counselling is discussed. Risk factors that render patients susceptible to erosive toothwear need to be identified in early life, if possible, as it may improve their treatment outcome through the instigation of preventive measures. Practical advice and the importance of education regarding timing of toothbrushing following an acid challenge should be given to patients. Availability of fewer erosive beverages may prove acceptable alternatives for some patients, especially where poor compliance is an issue. Some patients may benefit from intra-oral appliances to improve and maintain delivery of fluoride. The importance of fluoride use and of products such as Pronamel/Tooth Mousse aimed at preventing erosive tooth surface loss are discussed.

Abstract
Patients undergoing radical radiotherapy for head and neck cancers often experience significant complications. We sought to evaluate the impact of prophylactic gastrostomy tubes (PGTs) among these patients on four easily evaluable adverse outcomes, namely, absolute weight loss, percentage weight loss, admissions for nutritional reasons and treatment interruptions. A retrospective review was carried out on patients undergoing radical radiotherapy for primary head and neck cancers from September 1999 to October 2005 at the Wellington Blood and Cancer Centre (n = 71). PGTs were placed in 7 (10%) patients. Patients with PGTs were compared with the patients without PGTs (the control group) by univariate and multivariate analyses. By univariate analysis, there was no significant difference in absolute or percentage weight loss between those with PGTs and the control group. By multivariate analysis, those with PGTs lost 5.2% (P = 0.016) less weight than the control group. There were no significant differences between the two groups with regard to admissions for nutritional reasons or treatment interruptions. The use of PGTs can reduce weight loss in patients undergoing radical radiotherapy for head and neck cancers, and its use should be further evaluated in future studies.

Abstract
16515 Background: To evaluate the difference between acute and late effects of radical radiotherapy in elderly(above 60 years,Group A) head and neck cancer patients with young patients (below 50 years of age, Group B). Methods: The study was conducted on histologically proven head and neck cancer patients receiving radical radiotherapy (RT),49 patients were in group A and 40 in group B.The acute and late radiation morbidity was assessed using RTOG (phases I,II,&III- Pre RT, During RT & 1 month post RT respectively) and LENT-SOMA scoring systems (phases IV &V-3 & 6 months post RT). Results: In phase II, grade I dermatitis was commonly seen (83.7% in group A,72.5% in group B) and grade II dermatitis was 12.2 % vs 25% of patients.The difference in distribution over age was not significant (p= 0.12 & 0.18 in phase II and III).There was no significant difference in the incidence of late effects between two groups (p=0.91 in phase IV and p=0.99 in phase V).Grade II mucositits was seen in majority of patients in both groups,71.4% vs 72.5% in phase II.The late mucosal changes with worrisome subjective (pain) experiences were observed in 69.4% vs 75% of patients in group A and B, respectively.The difference in distribution over the age was significant (p<0.051) only in phase II.Dryness of mouth was the most common acute and late sequel of RT.The acute salivary gland morbidity was mostly moderate to complete dryness (grade II),seen in phases II and III in 24.5% & 73.5% of patients but the late sequel was seen in 83.37% of patients in group A and 85% in group B and the difference in late effects in both groups was statistically significant except in phase V (p= 0.02). Moderate dysphagia of grade II morbidity was seen in 75.5% vs. 65% in phase II. Grade III dysphagia was seen only 5 patients in group A and one in group B. In phase IV,66.7% patients in group A,72.5% in group B had persistent difficulty in swallowing. Conclusions: Grade I and II mucositis and dermatitis during the course of treatment led to increased morbidity, decreased nutritional intake and pain. Xerostomia is the most common and inevitable acute and late squeal of radical radiotherapy to head and neck cancer region resulting in difficulty in mastication and swallowing. There was no difference in the occurrence of acute and late effects between younger and elderly patients. No significant financial relationships to disclose.

Abstract
AIMS To determine the cerebrospinal fluid concentrations and the functional and pain outcomes after a single intravenous infusion of erythropoietin at the start of a standard radiotherapy and steroid protocol. MATERIALS AND METHODS Ten paraparetic patients with malignant extradural spinal cord compression who were eligible for radiotherapy, lumbar puncture and intravenous epoetin alpha were enrolled. The patients received epoetin alpha 1500 IU/kg intravenously over 30 min followed by a standardised dexamethasone and radiotherapy protocol. A lumbar puncture and venipuncture were carried out 24-30 h after the epoetin alpha infusion. The patients were followed closely at defined intervals. RESULTS Erythropoietin was detectable in the cerebrospinal fluid in all eight patients sampled (median 92.5 mIU/ml, range 17.8-214.0 mIU/ml). Before treatment, eight patients were non-ambulatory and two patients were ambulatory with assistance. After treatment, eight (80%, 95% confidence interval [CI] 44-97%) improved at least one functional class and recovered or maintained ambulation. Five of seven patients (71%; 95% CI 29-96%) with objective sensory deficits and one of seven (14%; 95% CI 0-58%) catheter-dependent patients recovered. Overall, 78% (95% CI 40-97%) had a pain response. CONCLUSIONS After an intravenous infusion of epoetin alpha, radiotherapy and steroids, high concentrations of erythropoietin were detectable in the cerebrospinal fluid. Patients with malignant extradural spinal cord compression showed encouraging improvements in neurological function and pain.

Abstract
5552 Background: To evaluate the Quality of life in patients above 60 and below 50 years during and after curative radiotherapy in head and neck cancers. Methods: Head and Neck cancer patients who are to undergo curative radiotherapy (RT) were divided into two groups, 49 patients (Group A,above 60 years) and 40 patients (Group B,below 50). Quality of life assessment was done using EORTC QLQ C-30 version-2 at 4 phases;Pretreatment-Phase I,during RT-Phase II,1-month post RT-Phase III and 6 months post RT-Phase IV.Statistical analysis was done with mean scores using ’t’ test. Results: Physical functioning (PF)scores in both groups were highest in phase I (69.4;77.5, p < 0.035) and lowest in phase II (40; 50, p < 0.008) and the difference was statistically significant. Although PF scores declined in both groups in phase II, overall PF score remained higher in group B than in group A in all phases.Role functioning score remained low in both groups and the difference were not statistically significant at all phases. Emotional functioning score was highest in phase I (68.37; 69.15), but declined as treatment progressed, consequent to depression.The values improved over time, restored to near pretreatment values at phase IV. Cognitive functioning scores in both groups was also highest in phase I (70.07; 79.17). Social functioning of both groups declined during RT (42.52; 45)compared to pre RT values (73.47; 77.09). The mean Global Health Status score was higher in group B compared to group A at all phases, yet there was no statistical significance.The scores declined during RT (66.87 vs 35.62 & 64.79 vs 34.01), improved overtime but did not reach pre RT scores.The symptom scores were all higher for elderly patients compared with younger patients at all phases, implying elderly patients experienced more symptoms, with greater experience of symptoms during RT. Conclusions: Quality of Life of elderly patients was lower compared to younger patients at phase II in terms of physical functioning, social and emotional functioning. Global Health Status score was higher for younger patients than elderly at all phases, and declined in phase II. No significant financial relationships to disclose.

Abstract
BACKGROUND Lung cancer is the most common cancer in the world accounting for 17.6% cancers worldwide. The AAR i n I ndian population varies f r om 0.98-15.55. The aim of t he present study was to analyze areduction in neoadjuvant chemotherapy related acute toxicity in locally advanced lung cancer (stage IIIA and III B) using Wobe Mugos E and its evaluation using micronuclei as a cytogenetic marker. Micronuclei, which are cytoplasmic fragments of DNA, have been used as a biological dosimeter to assess DNA damage. MATERIAL AND METHODS Fourty patients of locally advanced NSCLC were randomized into two study groups between 2001-2003. One group received neoadjuvant chemotherapy using Cisplatin and Etoposide. The other group received neoadjuvant chemotherapy using Cisplatin and Etoposide along with Wobe Mugos E which is a proteolytic enzyme preparation. A study of micronuclei frequency was done pre and post chemotherapy in both groups. RESULTS Thirty eight patients were available for final evaluation. Anemia was the most common hematological toxicity observed. Nausea and vomiting were the most common non -hematological toxicity seen. Wobe Mugos E was found to reduce the incidence of leucopenia (p = 0.005), nausea (p=0.004), vomiting (p= 0.003), sensory neuropathy (p = 0.032) and treatment related depression (p= 0.005). A reduction in micronuclei was seen in patients in patients on Wobe Mugos E. (p =0.01). CONCLUSION Neo-adjuvant chemotherapy related acute toxicity is a major problem in patients with advanced lung cancer. A reduction in micronuclei frequency shows Wobe Mugos E to be effective in reducing chemotherapy related acute toxicity.
