Post-operative vomiting after pediatric strabismus surgery: A comparison of propofol versus sevoflurane anaesthesia.

Background and Aims: Squint surgery is a risk factor for postoperative vomiting (POV) in children. This study was designed to compare the incidence of POV in children undergoing strabismus surgery under balanced anesthesia with sevoflurane versus intravenous anesthesia with propofol. Material and Methods: In this prospective randomized controlled study conducted in a tertiary care ophthalmology hospital, 70 ASA I-II children aged 1-12 years undergoing strabismus surgery were randomized to two groups -Group S (sevoflurane-based anesthesia) and Group P (propofol-based anesthesia) for maintenance. The surgical details, intraoperative hemodynamic parameters, recovery characteristics, and emergence delirium were recorded. Any episode of postoperative vomiting in the 0-2 hours, 2-6 hours, and 6-24 hours period was noted. Rescue antiemetic was administered if there was more than one episode of vomiting. Results: Both the groups were similar with respect to demographic and surgical details. The average duration of surgery was 118.2 ± 41.88 min in group S and 137.32 ± 39.09 min in group P (P = .05). Four children in group S (11.4%) and one child in group P (2.9%) had POV in the first 24 hours but this was not statistically significant (P = .36). The median time to discharge from post anesthesia care unit was significantly less (P = .02) in the P group (50 min) than in the S group (60 min). Conclusion: Propofol-based anesthesia does not offer advantage over sevoflurane, in reducing POV after squint surgery, when dual prophylaxis with dexamethasone and ondansetron is administered. It, however, reduces the duration of stay in the post anesthesia care unit.

Survival of patients with cervical cancer in India - findings from 11 population based cancer registries under National Cancer Registry Programme.

Background: Cancer survival data from Population Based Cancer Registries (PBCR) reflect the average outcome of patients in the population, which is critical for cancer control efforts. Despite decreasing incidence rates, cervical cancer is the second most common female cancer in India, accounting for 10% of all female cancers. The objective of the study is to estimate the five-year survival of patients with cervical cancer diagnosed between 2012 and 2015 from the PBCRs in India. Methods: A single primary incidence of cervical cancer cases of 11 PBCRs (2012-2015) was followed till June 30, 2021 (n = 5591). Active follow-ups were conducted through hospital visits, telephone calls, home or field visits, and public databases. Five-year Observed Survival (OS) and Age Standardised Relative Survival (ASRS) was calculated. OS was measured by age and clinical extent of disease for cervical cancers. Findings: The five-year ASRS (95% CI) of cervical cancer was 51.7% (50.2%-53.3%). Ahmedabad urban (61.5%; 57.4%-65.4%) had a higher survival followed by Thiruvananthapuram (58.8%; 53.1%-64.3%) and Kollam (56.1%; 50.7%-61.3%). Tripura had the lowest overall survival rate (31.6%; 27.2%-36.1%). The five-year OS% for pooled PBCRs was 65.9%, 53.5%, and 18.0% for localised, regional, and distant metastasis, respectively. Interpretation: We observed a wide variation in cervical cancer survival within India. The findings of this study would help the policymakers to identify and address inequities in the health system. We re-emphasise the importance of awareness, early detection, and increase the improvement of the health care system. Funding: The National Cancer Registry Programme is funded through intra-mural funding by Indian Council of Medical Research, Department of Health Research, India, Ministry of Health & Family Welfare.

Median effective dose of intranasal dexmedetomidine for satisfactory mask induction in children undergoing examination under anaesthesia for retinoblastoma - A prospective up and down sequential allocation study.

Background and Aims: Inhalational technique is used to induce anaesthesia in children without intravenous access. We aimed to determine the median effective dose (ED50) of intranasal dexmedetomidine to ensure satisfactory mask acceptance during inhalation induction in children with retinoblastoma undergoing examination under anaesthesia. Methods: A prospective sequential allocation study was conducted in children aged 1-60 months divided into Group A (1-18 months) and Group B (18-60 months). Children were administered dexmedetomidine intranasally as premedication. Sedation was assessed using the modified Observer Assessment of Alertness and Sedation Scale until induction. Successful mask acceptance was defined as a cooperative or asleep child during inhalational induction. The starting dose of dexmedetomidine was 1 µg/kg. The next dose varied by 0.2 µg/kg depending on the outcome of this case. According to the Dixon up-and-down method, the mean of midpoints of the failure-success sequence was calculated to obtain the ED50 values. Results: The ED50 of intranasal dexmedetomidine for satisfactory mask acceptance was 0.7 µg/kg (95% confidence interval [CI]: 0.54-0.86) in Group A (n = 23) and 0.96 µg/kg (95% CI: 0.83-1.08) in Group B (n = 25) (P = 0.020). The mean (standard deviation) duration of anaesthesia was 33.5 (14.9) minutes in group A versus 23.5 (8.48) minutes in Group B (P = 0.007). Conclusion: ED50 was lower in children younger than 18 months than in older children. There was no difference in the time to discharge from the post-anaesthesia care unit despite the procedure being longer in smaller children.

Grain iron and zinc content is independent of anthocyanin accumulation in pigmented rice genotypes of Northeast region of India.

The traditional rice genotypes of Assam are considered to have biological value due to the presence of several bioactive compounds like flavonoids, polyphenols, and anthocyanins, which have antioxidant, anti-cancer, anti-diabetic, and anti-aging properties. The pigmented genotypes are considered to have high iron (Fe) content. However, the effect of Fe and Zinc (Zn) accumulation on anthocyanin content is yet to be studied in pigmented rice of Assam. We studied the Fe, Zn, and anthocyanin content in grains of 204 traditional rice of Assam, which are traditionally preferred for their nutraceutical properties. We performed phenotypic and biochemical compositional analyses of 204 genotypes to identify those having high Fe, Zn, and anthocyanin. We also carried out the differential expression of a few selected Fe and Zn transporter genes along with the expression of anthocyanin biosynthesis genes. Interestingly, all pigmented rice genotypes contained a higher amount of phenolic compound than the non-pigmented form of rice. We found the highest (32.73 g) seed yield per plant for genotype Jengoni followed by Kajoli chokuwa and Khau Pakhi 1. We also listed 30 genotypes having high levels of Fe and Zn content. The genotype Jengoni accumulated the highest (186.9 µg g-1) Fe, while the highest Zn (119.9 µg g-1) content was measured in genotype Bora (Nagaon), The levels of Ferritin 2 gene expression were found to be significantly higher in Bora (Nagaon) (> 2-fold). For Zn accumulation, the genotype DRR Dhan-45, which was released as a high Zn content variety, showed significant up-regulation of the ZIP4 gene at booting (> 7-fold), post-anthesis (7.8-fold) and grain filling (> 5-fold) stages followed by Bora (Nagaon) (> 3-fold) at post-anthesis. Anthocyanidin synthase gene, Flavanone 3-dioxygenase 1-like (FDO1), and Chalcone-flavanone isomerase-like genes were up-regulated in highly pigmented genotype Bora (Nagaon) followed by Jengoni. Based on our data there was no significant correlation between iron and zinc content on the accumulation of anthocyanin. This challenges the present perception of the higher nutritive value in terms of the micronutrient content of the colored rice of Assam. This is the first report on the detailed characterization of traditional rice genotypes inclusive of phenotypic, biochemical, nutritional, and molecular attributes, which would be useful for designing the breeding program to improve Fe, Zn, or anthocyanin content in rice.

Breast cancer survival in India across 11 geographic areas under the National Cancer Registry Programme.

BACKGROUND: Population-based cancer survival is a key indicator for assessing the effectiveness of cancer control by a health care system in a specific geographic area. Breast cancer is the most common cancer among women in India, accounting for over one quarter of all female cancers. The objective of this study was to estimate the 5-year survival of female patients who were diagnosed with breast cancer between 2012 and 2015 from the existing Population-Based Cancer Registries (PBCRs) in India. METHODS: In total, 17,331 patients who had breast cancer diagnosed between 2012 and 2015 from 11 PBCRs were followed until June 30, 2021. Active methods were used to track the vital status of registered breast cancer cases. The study conducted survival analysis by calculating the difference between the date of first diagnosis and the date of death or censoring to estimate observed survival and relative survival using the actuarial survival approach and the Ederer-II approach, respectively. RESULTS: The 5-year age-standardized relative survival (95% confidence interval [CI]) of patients with breast cancer was 66.4% (95% CI, 65.5%-67.3%). Mizoram (74.9%; 95% CI, 68.1%-80.8%), Ahmedabad urban (72.7%; 95% CI, 70.3%-74.9%), Kollam (71.5%; 95% CI, 69.2%-73.6%), and Thiruvananthapuram (69.1%; 95% CI, 67.0%-71.2%) had higher survival rates than the national average. Conversely, Pasighat had the lowest survival rate (41.9%; 95% CI, 14.7%-68.6%). The 5-year observed survival rates for localized, regional, and distant metastasis in the pooled PBCRs were 81.0%, 65.5%, and 18.3%, respectively. CONCLUSIONS: The overall disparity in survival rates was observed across 11 PBCRs, with lower survival rates reported in Manipur, Tripura, and Pasighat. Therefore, it is imperative to implement comprehensive cancer control strategies widely throughout the country.

A Retrospective Study Comparing Laparoscopic Transabdominal Cerclage: Pre-Pregnancy Versus in Pregnancy With Their Reproductive Outcomes and Safety.

OBJECTIVES: To compare the efficacy of laparoscopic transabdominal cerclage (TAC) pre-pregnancy and laparoscopic TAC in pregnancy in treating cervical insufficiency. METHOD: A retrospective analytical study comparing outcomes of laparoscopic TAC pre-pregnancy with laparoscopic TAC in pregnancy. A total of 178 patients who underwent laparoscopic TAC at our hospital were enrolled in the study. In total, 122 patients underwent interval cerclage, and 56 patients underwent cerclage during pregnancy. RESULTS: A total of 178 patients who met the inclusion criteria were included in the analysis. Second-trimester abortions decreased by 50%, with an overall increase in full-term live births (32.53%) in patients undergoing laparoscopic TAC pre-pregnancy. The fetal survival rate was around 90% and 85% with laparoscopic TAC pre-pregnancy and laparoscopic TAC in pregnancy, respectively. Although the obstetric outcomes of laparoscopic TAC pre-pregnancy and in pregnancy were comparable, laparoscopic TAC pre-pregnancy was safer than laparoscopic TAC in pregnancy due to the complications associated with the procedure during pregnancy. CONCLUSIONS: Laparoscopic TAC pre-pregnancy yielded better reproductive outcomes than laparoscopic TAC in pregnancy and was associated with fewer perioperative complications.

Supramolecular Nanostructures for the Delivery of Peptides in Cancer Therapy.

Supramolecular nanostructured based delivery systems are emerging as a meaningful approach in the treatment of cancer, offering controlled drug release and improved therapeutic efficacy. The self-assembled structures can be small molecules, polymers, peptides, or proteins, which can be used and functionalized to achieve tailored release and target specific cells, tissues, or organs. These structures can improve the solubility and stability of drugs having low aqueous solubility by encapsulating and protecting them from degradation. Alongside, peptides as natural biomolecules have gained increasing attention as potential candidates in cancer treatment because of their biocompatibility, low cytotoxicity, and high specificity toward tumor cells. The amino acid sequences in peptide molecules are tunable, efficiently controlling the morphology of peptide-based self-assembled nanosystems and offering flexibility to form supramolecular nanostructures (SNs). It is evident from the current literature that the supramolecular nanostructures based delivery of peptide for cancer treatment hold great promise for future cancer therapy, offering potential strategies for personalized medicine with improved patient outcomes. SIGNIFICANCE STATEMENT: This review focuses on fundamentals and various drug delivery mechanisms based on SNs. Different SN approaches and recent literature reviews on peptide delivery are also presented to the readers.

In Vitro Insight on Antifungal-Specific Potentiality of Ni(II) Complex against Colletotrichum siamense and Fusarium equisetum Phytopathogens.

In an initiation to investigate a prospective bioactive compound, a mononuclear Ni(II) complex with N, N, and O donor Schiff base ligand was synthesized and characterized in the present study through FTIR, ESI-mass, and X-ray crystallographic diffraction studies. A slightly distorted octahedral geometry has been obtained for the Ni(II) complex from X-ray crystallographic diffraction studies. In vitro comprehensive biological studies show the antifungal specific efficiency of the complex against Colletotrichum siamense (AP1) and Fusarium equisetum (F.E.) pathogens, which are responsible for anthracnose and wilt disease, respectively, but no inhibitory effect on both Gram-positive and Gram-negative bacteria. The minimum inhibitory concentration (MIC) for these pathogens was observed to be 0.25 and 0.5 mM, respectively. The experiment also reveals that significant damage of mycelia and enlarged, misshaped damaged spores are noticed in comparison to hexaconazole, used as a positive control under a light microscope post 48 h treatment of AP1 and F.E. with the MIC of the complex. The binding interaction studies of the complex with DNA and BSA performed through a variety of spectroscopic techniques demonstrate a strong binding behavior of the complex for both the binding systems. The observed negative ΔH° and ΔS° values for DNA reveal the existence of hydrogen-bonding/van der Waals interactions for DNA which was also exemplified from the molecular docking and self-assembly studies of the complex. The positive ΔH° and ΔS° values for BSA demonstrate the hydrophobic interactions of the complex with BSA. However, cytotoxicity studies against the MDA-MB-231 breast cancer cell line did not demonstrate any significant potentiality of the complex as an anticancer agent. All the bio-experimental studies provide clear evidence that the synthesized Ni(II) complex exhibits potential antifungal activity and could be used as a therapeutic fungicide agent in comparison to hexaconazole in agricultural practices.

Neoadjuvant chemotherapy for locally advanced head and neck squamous cell carcinoma - Is it still relevant? A practice pattern survey among oncologists of India.

Objectives: Concurrent chemotherapy is the recommended treatment for locally advanced head and neck (H&N) squamous cell carcinoma, and neoadjuvant chemotherapy (NACT) is debated with a few special indications. NACT for advanced head and neck cancer has been studied in clinical trials for more than 2 decades without clear demonstration of the benefit for loco regional tumor control or overall patient survival. Its benefit remains controversial in the absence of clear evidence to define its role. However, there is widespread use of NACT among oncologists. We conducted an online survey to find out the frequency, pattern, prevalence, and aims for use of NACT in locally advanced head and neck cancers among radiation, medical, and surgical oncologists. Materials and Methods: Oncologists across India who expressed interest to participate in our survey were asked to complete a short online questionnaire designed to identify the current practice pattern of NACT in head and neck cancer. A mobile app-based questionnaire was sent to 200 oncologists across the country to assess the pattern of NACT use and to solicit their most frequent therapy approach for patients with locoregionally advanced head and neck cancer. Results: One hundred and fifty (150) oncologists completed and returned the survey (75%), and 130 were finalized (94 radiation oncologists, 19 medical oncologists, and 17 surgical oncologists). The single most common treatment approach reported for patients with locoregionally advanced H&N cancer was that of sequential chemoradiation (61%), specifically NACT with the TPF regimen (78.5%), followed by radiation therapy. The primary objectives cited by respondents for the use of NACT included the desire to buy time for definitive treatment (20%) and to achieve R0 resection (19.2%). Use of NACT in most patients was more preferred by medical oncologists (21.1%) and radiation oncologists (19.1%) than surgical oncologists (11.8%). Thus, there is not much difference in perception in practice of NACT in radiation, medical, and surgical oncologists. A minimum of two cycles of NACT was preferred by more than half of the doctors (55.4%) with 59.6% radiation oncologists using it before further assessment. Conclusion: Although level I evidence for inferior outcomes with NACT as compared to concurrent chemoradiation therapy is there, the use of NACT is quite common among various oncologists in the country because of reasons such as buying time for definitive treatment, achieving R0 resection, better outcome and survival, partial response, better tolerability, better distant control, LN size regression, down-staging of primary tumor, selection of chemosensitive patients, reducing the volume of the radiation field, and better tolerability of subsequent Chemoradiation (CTRT) intensity of subsequent chemoradiation therapy.

Controlling the Energetic Properties of N-Methylene-C-Linked 4-Hydroxy-3,5-dinitropyrazole- and Tetrazole-Based Compounds via a Selective Mono- and Dicationic Salt Formation Strategy.

In the quest to synthesize high-performing insensitive high-energy density materials (HEDMs), the main challenge is establishing an equilibrium between energy and stability. For this purpose, we explored 4-hydroxy-3,5-dinitropyrazole- and tetrazole-based energetic scaffolds connected via a N-methylene-C bridge. The hydroxy functionality between nitro groups on the pyrazole ring promotes physical stability via inter- and intramolecular hydrogen bonding and contributes to oxygen balance, supporting better energetic performance. Due to two acidic sites (OH and NH) with different reactivities, a series of monocationic and dicationic salts were synthesized, and their overall performance was compared. All compounds synthesized in this study have high physical stability with impact sensitivity >40 J and friction sensitivity >360 N. Monocationic salts were generally found to have better thermal stability with respect to their corresponding dicationic energetic salts, which showed better energetic performance. The salt formation strategy effectively improved the thermal stability of 2 (Td = 168 °C), where most energetic salts have decomposition temperatures higher than 220 °C. All of the compounds were characterized through IR, multinuclear NMR spectroscopy, high-resolution mass spectrometry (HRMS), and elemental analysis. The structure-property relationship was studied using Hirshfeld surface analysis, noncovalent interaction (NCI) analysis, and electrostatic potential studies.

Over Expression of Cancer Stem Cell Marker CD44 and Its Clinical Significance in Patients with Oral Squamous Cell Carcinoma.

Cancer stem cell marker CD44 is a cell-surface glycoprotein which is involved in various cellular functions such as cell-cell interactions, cell adhesion, haematopoiesis and tumour metastasis. The CD44 gene transcription is partly activated by beta-catenin and Wnt signalling pathway, the later pathway being linked to tumour development. However, the role of CD44 in oral squamous cell carcinoma (OSCC) is not well understood. We investigated the expression of CD44 in peripheral circulation, tumour tissues of oral cancer patients and oral squamous cell carcinoma cell lines by ELISA and quantitative (q)-RTPCR. Relative CD44s mRNA expression was significantly higher in peripheral circulation (p = 0.04), tumour tissues (p = 0.049) and in oral cancer cell lines (SCC4, SCC25 p = 0.02, SCC9 p = 0.03). Circulating CD44total protein levels were also significantly (p < 0.001) higher in OSCC patients that positively correlated with increasing tumour load and loco-regional spread of the tumour. The circulating tumour stem cell marker CD44 appears to be a potent indicator of tumour progression and may be useful for developing suitable therapeutics strategies for patients with oral squamous cell carcinoma.

Need for accelerating tobacco control in India: findings from the national cancer registry programme.

OBJECTIVE: To describe the epidemiology of cancer in sites associated with tobacco use in India, according to recent findings from the National Cancer Registry Programme. METHODS: The data on cancers in sites associated with tobacco use has been sourced from 28 population-based and 58 hospital-based cancer registries of the National Cancer Registry Programme in India. The data covering a period of 5 years (2012-2016) was taken up for analysis. RESULTS: The highest age-adjusted incidence rate (AAR) among males was reported in the Aizawl district in Mizoram (197.3 per 100 000). The AAR was the highest (121.1 per 100 000) in the Papumpare district in females. The top five leading sites were cancers of the lung (10.7%), mouth (8.7%), oesophagus (6%), tongue (6%) and stomach (5%) among males and cancer of the cervix (10.3%), lung (4.3%), oesophagus (3.3%), mouth (3.3%) and tongue (2.7%) in females. The highest significant increase in AAR, indicated by the annual percentage change was seen among males in Aurangabad (3.4) and females in Kamrup urban (2.4). Except for lung cancer, most patients with other cancer types among both genders presented to the health facility with a locoregional (spread to nearby lymph nodes) disease spread. It is projected that in 2025, there will be 694367 cases of cancers in the sites associated with tobacco use. CONCLUSION: Tobacco uses in either form and cancer in sites associated with tobacco use are an important matter of public health concern in India. Cancer registries play a crucial role in identifying populations with high cancer incidence in sites associated with tobacco use, monitoring the trends over time, and evaluating the impact of tobacco control measures.

Cancer incidence estimates for 2022 & projection for 2025: Result from National Cancer Registry Programme, India.

Background & objectives: Information on recent cancer statistics is important for planning, monitoring and evaluating cancer control activities. This article aims to provide an update on the cancer incidence estimates in India by sex, age groups and anatomical sites for the year 2022. Methods: The National Cancer Registry Programme Report 2020, reported the cancer incidence from 28 Population-Based Cancer Registries (PBCRs) for the years 2012-2016. This was used as the basis to calculate cancer estimates in India. Information pertaining to the population at risk was extracted from the Census of India (2001 and 2011) for the estimation of age-sex stratified population. PBCRs were categorised into the respective State and regions of the country to understand the epidemiology of cancer. The age-specific incidence rate for each specific anatomical site of cancer was applied to the estimated population to derive the number of cancer cases in India for 2022. Results: The estimated number of incident cases of cancer in India for the year 2022 was found to be 14,61,427 (crude rate:100.4 per 100,000). In India, one in nine people are likely to develop cancer in his/her lifetime. Lung and breast cancers were the leading sites of cancer in males and females, respectively. Among the childhood (0-14 yr) cancers, lymphoid leukaemia (boys: 29.2% and girls: 24.2%) was the leading site. The incidence of cancer cases is estimated to increase by 12.8 per cent in 2025 as compared to 2020. Interpretation & conclusions: The cancer incidence is continuing to increase in India. The new estimates will be helpful in planning cancer prevention and control activities through the intervention of early detection, risk reduction and management.

Epidemiology of human papillomavirus related cancers in India: findings from the National Cancer Registry Programme.

Human papillomavirus (HPV) causes more than one-fourth of infection related cancers globally. The present study summarises the epidemiology of HPV related cancers in India, with a special focus on cervical and oropharyngeal cancer, utilising the National Cancer Registry Programme (NCRP) data. The data on HPV related cancer incidence and treatment were extracted from 28 population-based and 96 hospital-based cancer registries under the NCRP network. Incidence was presented as rates, clinical extent of disease and treatment provided as percentages. Joinpoint regression analysis was performed to calculate annual percent change in age adjusted incidence rates (AARs) over time. Incidence of HPV related cancers for 2025 was projected. Among all cancers, 7.5% were HPV related cancers. Cervical cancer (87.6%) and oropharyngeal cancer (63.2%) were the most common HPV related cancers in India among females and males, respectively. Cervical cancer was highest in Papumpare district (AAR: 27.7 per 100,000) and oropharyngeal cancer among males in East Khasi Hills district Population Based Cancer Registry (AAR: 11.4 per 100,000). In most PBCRS, cervical cancer incidence rate decreased significantly over the period of time. The majority of these cancers presented at locoregional spread stage of the disease and were treated with chemoradiation. The projected incidence of HPV related cancers is expected to increase to 121,302 by 2025. Implementation of effective prevention and control strategies like HPV vaccination and scaling up of screening could reduce the burden of HPV related cancers. Evidence from NCRP serves as the baseline to monitor the impact of HPV related policies and programmes in improving the outcome and prognosis.

Women cancers in India: Incidence, trends and their clinical extent from the National Cancer Registry Programme.

BACKGROUND: To provide a comprehensive assessment of women cancer in India utilizing the systematically collected data on all cancers by the National Cancer Registry Programme (NCRP). METHODS: The study examined 10,2287 cancer cases among women cancers providing cancer burden for major anatomical sites. Aggregated data of 28 PBCRs and 58 HBCRs under NCRP for 2012-16 was analysed for incidence rates, trends, cumulative risk of developing cancer, stage at detection and treatments offered. RESULTS: Study results have found region -wide variation of women cancers by indicating highest proportions in western followed by southern region of India. North-Eastern region had lowest proportion. It was observed that breast is highest ranking cancer in most registry areas of urban agglomerations of country while cancer cervix was leading site in registries of rural areas like Barshi (15.3) and Osmanabad &Beed (13.1). States of Mizoram (23.2) and Tripura (9.5) along with Pasighat, Cachar and Nagaland. Median age of occurrence for women for these anatomical sites ranged from 45 to 60 years of age. For cancer breast, cervix and ovary -most cases were detected with regional spread. These findings were different for cancer corpus uteri where registries have reported higher proportions (49.3 %) of localized stage at detection. Loco regional cancers had higher proportions of multimodality treatments. CONCLUSION: Study provides a foundation for assessing the status of women cancers in the country. Variations between geographies would guide appropriate support for action to strengthen efforts to improve cancer prevention and control in underserved areas of the country. This would facilitate advocacy for better investments and research on women cancers.

A clinicoepidemiological profile of lung cancers in India - Results from the National Cancer Registry Programme.

Background & objectives: Lung cancer is a significant public health concern in low- and middle-income countries such as India. The present article describes the epidemiology, and clinical profile of lung cancer in India, based on recent data from the National Cancer Registry Programme (NCRP). Methods: The latest data on lung cancer from the NCRP were collated from 28 population-based cancer registries and 58 hospital-based cancer registries across a five-year (2012-2016) reporting period. Results: The highest age-adjusted incidence rate and mortality (AAMR) was found amongst males and females in the Aizawl district of Mizoram. A significant increase in the annual per cent change of lung cancer incidence was observed in metropolitan cities from 1982 to 2016. About one-third of the cases (36.5%) in males and females (31.7%) were recorded in the age group of 55-64 yr. Adenocarcinoma accounted for about a third (34.3%) of the morphological type in males and half (52.7% ) amongst females. Out of 22,645 recorded lung cancer cases, close to half (44.8%) of the patients presented with distant spread, while over one-third (35.3%) had loco-regional spread of disease at the time of diagnosis. Interpretation & conclusions: Our estimates suggest that the number of cases is expected to rise sharply to 81,219 cases amongst males and 30,109 in females in 2025. The rising incidence and delayed diagnosis of lung cancer in India are grave concerns. The findings of the present study call for scaling up and intensification of lung cancer-specific preventive, early diagnosis and control measures.

Nitric-Oxide Synthase trafficking inducer (NOSTRIN) is an emerging negative regulator of colon cancer progression.

BACKGROUND: NOSTRIN, abundantly expressed in colon, was reported to be anti-angiogenic, anti-invasive and anti-inflammatory. NOSTRIN expression was inversely related to survival of pancreatic ductal adeno-carcinoma patients. Yet its function and regulatory mechanism in CRC remains elusive. METHODS: NOSTRIN's influence on EMT of CRC cells were analysed using realtime PCR array containing the functional EMT-transcriptome followed by western blotting. Regulation of oncogenic potential of CRC cells by NOSTRIN was elucidated using soft agar colony formation, trans-well invasion, wound healing and colonosphere formation assays. Biochemical assays were used to reveal mechanism of NOSTRIN function. Human CRC tissue array was used to test NOSTRIN mark in control and CRC disease stages. RESULTS: We showed here that CRC cell lines with less NOSTRIN expression has more invasive and migratory potential. NOSTRIN affected EMT-associated transcriptome of CRC cells by down regulating 33 genes that were functionally annotated to transcription factors, genes important for cell growth, proliferation, migration, cell adhesion and cytoskeleton regulators in CRC cells. NOSTRIN over-expression significantly reduced soft agar colony formation, wound healing and cell invasion. In line with this, RNA interference of Nostrin enhanced metastatic potential of CRC cells. Furthermore, stable overexpression of NOSTRIN in CRC cell line not only curtailed its ability to form colonosphere but also decreased expression of stemness markers CD133, CD44 and EpCAM. NOSTRIN's role in inhibiting self-renewal was further confirmed using BrdU incorporation assay. Interestingly, NOSTRIN formed immune-complex with Cdk1 in CRC cells and aided in increase of inhibitory Y15 and T14 phosphorylation of Cdk1 that halts cytokinesis. These ex vivo findings were substantiated using human colon cancer tissue array containing cDNAs from patients' samples with various stages of disease progression. Significant decrease in NOSTRIN expression was found with initiation and progression of advanced colon cancer disease stages. CONCLUSION: We illustrate function of a novel molecule, NOSTRIN in curtailing EMT and maintenance of CRC cell stemness. Our data validates importance of NOSTRIN mark during onset and disease progression of CRC indicating its diagnostic potential.

Descriptive Epidemiology of Gastrointestinal Cancers: Results from National Cancer Registry Programme, India.

PURPOSE: This study aims to determine the incidence, histology, clinical extent of disease, and trends of gastrointestinal (GI) cancers in India. METHODS: GI cancer cases diagnosed between 2012-2016 from 28 Population-Based Cancer Registries and 58 Hospital Based Cancer Registries under the National Cancer Registry Programme were included. Crude incidence rate and age-standardized incidence rates (AARs) were calculated. Joinpoint regression program, 4.0.1 was used for trend analysis for data from 1982 to 2016, and a P-value of <<0.05 was considered statistically significant. RESULTS: GI cancers' occurrence was more common among men (60.5%) than in women (39.5%). The incidence of GI cancer was highest in India's northeast region, Aizawl district (AAR 126.9) among males, and in Papumpare district (AAR 75.9) among females. The commonest cancer among men was cancer of the esophagus (28.2%), followed by stomach cancer (21%) and rectum cancer (14.3%). Among women, cancer of the esophagus (25.7%), gallbladder (23.8%), stomach (14.8%), and rectum (14.6%) were common. Adenocarcinoma (57.83%) was the commonest type of GI tumors, followed by Squamous Cell neoplasms (25.99%). Majority of the GI cancers presented at the locoregional stage, but cancer of the gall bladder and pancreas presented at advanced stages. A rising trend for cancers of the colon, rectum, liver, gall bladder, pancreas was seen, while a declining trend was observed for stomach and oesophageal cancer. CONCLUSION: Our study highlights an increasing magnitude of GI cancers across different regions of India. Cancer registries form an essential tool for surveillance of GI cancers thus guiding prevention, early detection, and control programs.

Cancer scenario in North-East India & need for an appropriate research agenda.

Background & objectives: The North-Eastern (NE) region has the highest incidence of cancer in India, and is also burdened by higher prevalence of risk factors and inadequate cancer treatment facilities. The aim of this study was to describe the cancer profile of the NE region, focussing on the cancer sites that have high incidence and to identify research priorities. Methods: Incidence data from population-based cancer registries (PBCRs) in the North-East region (8 States) were utilized and relevant literature was reviewed to identify risk factors. Results: Aizawl district in Mizoram had the highest incidence of cancer in men [age-adjusted rate (AAR) of 269.4 per 100,000]. Among women, Papumpare district of Arunachal Pradesh had the highest incidence (AAR of 219.8) in India. East Khasi Hills district in Meghalaya had the highest incidence of oesophageal cancer (AAR of 75.4 in men and 33.6 in women). Aizawl district in Mizoram had the highest incidence of stomach (AAR-44.2 in men) and Papumpare district had highest incidence of stomach (AAR 27.1 in women), liver (AAR- 35.2 in men and 14.4 in women) and cervical cancers (AAR- 27.7). Lung cancer (AAR- 38.8 in men and 37.9 in women) and gall bladder cancer incidence (AAR- 7.9 in men and 16.2 in women) were highest in Aizawl and Assam (Kamrup urban) PBCRs, respectively. Nagaland had the highest incidence of nasopharyngeal cancer (AAR of 14.4 in men and 6.5 in women), a relatively rare cancer in other regions of India. Four States (Arunachal Pradesh, Manipur, Sikkim and Tripura) in NE had only one cancer treating facility. Interpretation & conclusions: Further research on specific aetiological factors in the region and multi-disciplinary research for development of tools, techniques and guidelines for cancer control are the need of the hour.
