Epidemiological trends of colorectal cancer cases in young population of Eastern India: A retrospective observational study. J Cancer Res Ther 2024; 20:817-821. [PMID: 39023588 DOI: 10.4103/jcrt.jcrt_2367_22] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/09/2022] [Accepted: 12/08/2022] [Indexed: 07/20/2024]
Abstract
BACKGROUND Colorectal cancer (CRC) is a disease of the older population in developed countries where the incidence among the young is rising despite the decline in the overall incidence. Contrary to this, in India, which is a low-incidence country for CRCs, the incidence among all age groups including the young is rising. This study aimed at describing the clinico-demographic profile of young CRC cases and the epidemiological trend of the proportion of young cases from 2014 to 2021 in a tertiary cancer center in Eastern India. METHODS This retrospective observational study was conducted at Department of Radiation Oncology, State Cancer Institute, IGIMS Patna, India a prominent tertiary cancer care center of Bihar. All histopathologically confirmed CRC cases in the 0-39 years age group were considered young and evaluated for the clinical, demographic profile as well as yearly trends in proportion out of total CRC cases. Microsoft Excel (2021) was used for statistical analysis. A P value of 0.05 was considered significant. RESULTS Young colorectal (less than 40 years) patients constituted a third (n = 344, 33.4%) of total colorectal (n = 1028) cases. The median age among the young CRC cases was 30 years (range: 12 to 39 years). Rectum was the most common subsite noted (n = 255,74.1%) among this group of young patients. The most commonly encountered stage of the disease was III (n = 107, 31.1%) and chemotherapy was the most common treatment offered (n = 153, 44.5%). The proportion of young (0-39 years) CRC cases ranged between 29.4 and 37.4 (mean 33.5 ± 2.77, P value = 0.725) over the calendar years of the study period. CONCLUSION The proportion of young (<40 years of age) cases out of total CRC cases in our study is higher than that in developed countries. However, the trends of this proportion have been consistent over the study period, i.e., from 2014 to 2021 without any significant change in our hospital-based cancer registry. Rectal cancer affected nearly three out of every four CRC patients in this age group. More advanced disease at presentation emphasizes the need for measures of screening, early diagnosis, and adequate infrastructure for treatment.

Abstract
Background In the past two decades, the growing economy associated with changes in lifestyle-related behavior is partially responsible for the increasing cancer burden in India. To assess the occurrence and distribution of oral cancer based on the analysis of hospital records from registered oncology institutes of South India over a period of three years. Materials and Methods A multicenter, retrospective study was conducted at seven major hospitals in South India to assess the incidence and distribution of cancer among patients over a period of three years (2016-2018). Data were collected on a custom-made validated proforma. Analysis was done using R commander software. Results A total of 156090 various types of cancers were reported to the included institutes over a three-year period, an almost similar gender distribution was observed, males (n = 78806, 42.99% per lakh) compared to their female counterparts (n = 77284, 42.16% per lakh). Among males' lung cancer was the most common type with 17709 cases (9.65% per lakh) and among females, breast cancer was the leading cancer type with 22855 total cases (12.46% per lakh). Over a period of three years, a total of 21084 records of malignancies pertaining to oral cavity were identified accounting for 13.51% of cases. Among oral cancers, tongue was the most common site to be involved accounting for 44.22% (2016-2018) cases followed by buccal mucosa (14.69%), least common site to be involved was lip which accounted for 3.49% of the total oral cancer cases. Conclusion Breast cancer was the most common cancer followed by lung cancer. Oral cancers occupied second among males and fifth rank in the order of occurrence among females. Tongue was the most common site followed by buccal mucosa. The least common site affected by oral cancer was the lip.

Abstract
Objective To investigate the trends and patterns of the cancer burden among the elderly in different regions of India at a subnational level. Methods Data were extracted from the Global Burden of Disease (GBD) Studies India Compare 2019. Prevalence rate, disability-adjusted life years (DALY), and annual percentage change techniques were used to analyze data. Results The three age groups with the highest prevalence of cancer were those aged 60-64 years, 65-69 years, and 70-74 years. In 2019, The prevalence of cancer among the elderly ranged from 7048.815 in Karnataka to 5743.040 in Jharkhand. Kerala has the most significant annual percentage change in the cancer prevalence rate of 0.291 between 1990 and 2019. The highest DALY rate was observed among individuals aged 80-84 years in 2019. That year, the DALY rate among the elderly was 8112.283 in India. The top five cancers with higher DALY rates among the elderly in India in 2019 were tracheal, bronchus, and lung cancer (908.473), colon and rectum cancer (752.961), stomach cancer (707.464), breast cancer (597.881), and lip and oral cavity cancer (557.637). Conclusion Elderly individuals demonstrated a higher vulnerable to cancer compared to other age groups. There is a need for state-specific government intervention to minimize the risk of cancer among the elderly due to the heterogeneity in the burden of cancer across Indian states.

Abstract
Introduction Despite advances in treatment, there is rising mortality in elderly patients with breast cancer. We aimed to conduct an audit of non-metastatic elderly breast cancer patients to understand the predictors of outcome. Methods Data collection was done from electronic medical records. All time-to-event outcomes were analysed using Kaplan-Meier method and compared using log-rank test. Univariate and multi-variate analysis of known prognostic factors was also done. Any p-value ≤0.05 was considered statistically significant. Results A total of 385 elderly (>70 years) breast cancer patients (range 70-95 years) were treated at our hospital from January 2013 to December 2016. The hormone receptor was positive in 284 (73.8%) patients; 69 (17.9%) patients had over-expression of HER2-neu, while 70 (18.2%) patients had triple-negative breast cancer. A large majority of women (N = 328, 85.9%) underwent mastectomy while only 54 (14.1%) had breast conservation surgery. Out of 134 patients who received chemotherapy, 111 patients received adjuvant, while the remaining 23 patients received neoadjuvant chemotherapy. Only 15 (21.7%) patients of the 69 HER2-neu receptor-positive patients received adjuvant trastuzumab. Adjuvant radiation was given to 194 (50.3%) women based on the type of surgery and disease stage. Adjuvant hormone therapy was planned using letrozole in 158 (55.6%) patients, while tamoxifen was prescribed in 126 (44.4%). At the median follow up of 71.7 months, the 5-year overall survival, relapse-free survival, locoregional relapse-free survival, distant disease-free survival, breast cancer-specific survival were 75.3%, 74.2%, 84.8%, 76.1% and 84.5%. Age, tumour size, presence of lymphovascular invasion (LVSI) and molecular subtype emerged as independent predictors of survival on multi-variate analysis. Conclusion The audit highlights the underutilisation of breast-conserving therapy and systemic therapy in the elderly. Increasing age and tumour size, presence of LVSI and molecular subtype were found to be strong predictors of outcome. The findings from this study will help to improve the current gaps in the management of breast cancer among the elderly.

Abstract
Background and objectives Cancer is one of the major causes of illness and mortality in India. The cancer burden in India will roughly triple over the next 20 years. Population-based cancer registries (PBCRs) are crucial not only for formulating cancer control policies and assessing their effectiveness but also offer essential inputs for programs aimed at preventing cancer. The state of Andhra Pradesh after the division in 2014 has been left with no PBCR. Hence, with the aim to pilot the development of a population-based cohort of cancer cases with digital reporting and monitoring mechanisms, this study was carried out with the objective of finding the prevalence and incidence of various types of cancer in Mangalagiri Mandal, Guntur district, Andhra Pradesh. Materials and methods A cross-sectional survey during the period January 2021 to June 2022 was conducted to actively search for cancer cases among 160303 people residing in 42639 households in the Mangalagiri Mandal, Guntur district, State of Andhra Pradesh, India. The respondents were asked if anyone in the household had cancer and the location was mapped, the information was recorded by the Accredited Social Health Activist (ASHA) workers in the pre-tested questionnaire. The total number of cancer cases identified was 107. Results Mangalagiri Mandal had 24 cases of cancer among men and 83 cases of cancer among women as recorded during the study period. Most of the male (37.5%) and female (31.3%) cancer cases were in Stage 2 of cancer and the majority of them (91.6%, 94%) had completed their treatment and were on regular follow-up. The most common cancer among both sexes was breast cancer (5.45 per million population). Oral cancer was the most prevalent in men (0.747 per million of the population) whereas, breast cancer (4.253 per million population) was the most prevalent among females. A total of 47.1% of the males had cancer at sites that were related to tobacco usage. Conclusion The data on cancer incidence and prevalence along with the socio-demographic profile is essential to know the burden of cancer. This baseline data can be used in planning cancer control activities and knowing the future trend of cancer in the Mangalagiri Mandal, in the new state of Andhra Pradesh.

Abstract
INTRODUCTION Ovarian and breast cancers are highly prevalent in the population of Jammu and Kashmir (J&K). However, case-control association studies on breast and ovarian cancers are lacking in this population. Moreover, no case-control study is available on variant rs10937405 of TP63 in breast and ovarian cancers. Thus, we designed to replicate the cancer susceptible variant rs10937405 of TP63 in ovarian and breast cancers in the population of J&K because the TP63 gene act as a tumor suppressor gene and was previously associated with various cancers. MATERIALS AND METHODS This case-control association study conducted at the Shri Mata Vaishno Devi University, includes 150 breast, 150 ovarian cancer cases, and 210 healthy controls (age and sex-matched). Variant rs10937405 of the TP63 gene was determined by the TaqMan assay. Hardy-Weinberg equilibrium for the variant was assessed using the Chi-square test. The allele and genotype-specific risks were estimated by odds ratios (ORs) with 95% confidence intervals (CI). RESULTS In this study, variant rs10937405 of TP63 gene did not show any risk with ovarian and breast cancer with (P-value = 0.70) having OR 0.94, (0.69-1.28 at 95% CI) and (P-value = 0.16) having OR 0.80, (0.59-1.10). DISCUSSION Our results indicate that the variant rs10937405 of the TP63 gene did not impart any risk of breast and ovarian cancer in the population of J&K. Our results indicate that a larger sample size is needed for further statistical validation. As the study was for a particular variant, it warrants the analysis of other variants of this gene.

Abstract
Background of the Study As many as 10 million people have died from cancer globally in 2020, making it the top cause of mortality in the globe. Cancer develops as a result of the multi-stage process by which normal cells convert into tumor cells, progressing from a precancerous lesion to a malignant tumor. By avoiding risk factors and applying existing evidence-based preventative techniques, 30%-50% of malignancies may be averted. In order to avoid cancer, it is essential to know the specific causes of the disease. Nidanas, or etiologies, are well-described in Ayurvedic science. Here, the causes of cancer have been outlined so that the knowledge may be used effectively to avoid the disease. Aims Identification of cancer etiologies that have been described in classics. Evidence-based understanding of these etiologies and to comprehend the significance of etiologies in cancer prevention. Materials and methods A thorough evaluation of literature, including ancient Ayurvedic classics, modern medical texts, and articles published in reputable journals, was conducted to meet the study's goals and objectives. Results According to Ayurveda, there are three distinct phases of tumorigenesis: chronic inflammation, precancerous development, Granthi (a benign glandular swelli ng), and Arbuda (a precancerous tumor) (definite malignancy). A growing body of evidence suggests that the tumor microenvironment, which is predominantly controlled by inflammatory cells, is an essential player in the neoplastic process. Conclusion Although inflammation is coming into the picture just now in the contemporary world, Ayurveda has described this as a leading cause 5000 years back. It is evident that diet and lifestyle play a crucial role in the etiology of Shoth (inflammation).

Abstract
Abstract
Introduction Cancer is emerging as a major health problem worldwide. Profile and pattern of cancers vary as per the geographic, ethnic, and sociocultural background of the population. It is imperative to know the change in the pattern of cancer in the population to formulate an effective strategy for its control and management.
Objective To study the changing trends and epidemiological distribution of common cancer types in an ethnic population of Northern India.
Materials and Methods In this retrospective observational study, we audited records of 22,188 patients with histologically documented cancer registered between January 2014 and December 2018 in the regional cancer center of a tertiary care institute in North India. For all identified patients, medical records were reviewed for demographic information (age of diagnosis, sex, type of cancer, and select risk factors). The data analysis was done using IBM SPSS Statistics for Windows from IBM Corp. Data were expressed as frequencies with percentages. The incidence and trends were depicted through tables, and line diagrams were used to show the changes (if any) over the last 5 years.
Results The most common cancer reported in the last 5 years was lung cancer, overall (10.6%; 95% confidence interval [CI], 10.2–11.0) as well as in men (14.8%; 95% CI, 14.2–15.4) and breast cancer in females (13.5%; 95% CI, 12.8–14.2). The top five cancers reported at our center were lung (10.6%), esophagus (9.1%), stomach (9.0%), breast (6.0%), and colon (3.8%). Compared with that, the top five cancers reported from our center in 2012 were esophagus and gastroesophageal junction (17.2%), lung (11.9%), stomach (9.7%), colorectal (7.1%), and breast (6.5%). Prostate cancer was reported in 3.4% of cases, which was much higher than that reported in 2012 (1.7%). Surprisingly, thyroid cancer (6.4%) was the fourth commonest cancer reported in females, while it did not figure in the top 10 cancers in the 2012 report. Expectantly, cervix cancer did not figure among the top 10 cancers in women.
Conclusion There is a change in the pattern of cancers. Lung and breast have emerged as the most commonly occurring cancers in men and women, respectively, whereas there was a slight downward trend in the incidence of esophageal cancer.

Methods For this retrospective single center study, all patients with age > 18 years undergoing colonoscopy from January 2018 to December 2019 were included. Age, gender, and polyp characteristics were collected from endoscopy and histology database. Patients with incomplete histology reports and anal canal polyps were excluded. Based on histology, polyps were divided into adenocarcinoma, adenoma with advanced pathology (AAP; size > 10 mm, villous morphology or high-grade dysplasia), nonadvanced adenomas (nAAP), and nonadenomas.
Results Overall colon polyp prevalence was 10.18% (3551/34893). The mean age (standard deviation [SD]) was 51.51 (14.84) with 75.4% males, of which 128 (3.6%) were adenocarcinoma. A total of 1514 (42.64%) were adenomas; 344 (9.7%) were AAP and 1170 (32.9%) were nAAP. The remaining 1909 (53.8%) were nonadenomas. Colonic adenoma prevalence after excluding adenocarcinoma was 4.35% (1514/34893). Adenocarcinoma (68.8% vs. 31.2%), AAP (70.6% vs. 29.4%), other adenomas (75.4% vs. 24.6%), and nonadenomas (76.7% vs. 23.3%) were significantly higher in male compared with female (p < 0.05). Adenomas and adenocarcinomas were more common in left colon and rectum than right colon (p < 0.05). The mean age (SD) were significantly lower in nonadenomas than adenocarcinomas, AAP, and other adenomas (p 0.0001; 49.25 [14.84] vs. 55.97 [12.47], 54.78 [16.40], 53.76 [13.71]).
Conclusions The prevalence of colonic adenoma in India is 4.35%. Male gender and increased age were associated with increased risk of colonic adenoma and adenocarcinoma, which is more common in left colon and rectum. Prospective multicenter studies are required for evaluation of other risk factors of CRC and colonic adenomas.

Abstract
BACKGROUND The alarming escalation of cancers over infectious diseases in the lower and middle-income countries warrants a better understanding of this epidemiological transition. The epidemiology of cancers in India is sparsely addressed in the literature. Hence, in this manuscript, we present the review done, on research manuscripts, addressing cancer incidence, trends and risk factors from India over the last 12 years. Studies addressing screening, treatment and clinical trials were excluded. METHODS We evaluated the studies for the theme addressed, study design, sample size, the region of origin and whether it was population or hospital-based study. RESULTS The studies highlighted a significant shortage of multicenter population-based data in the incidence and risk factors associated with various malignancies in India. Further, we also observed that there was a relative lack of information from the northern and northeastern parts of India. The reviewed articles also indicated the need for a robust design for the studies, large sample size and uniformity in reporting incidence for appropriately drawing conclusions from a study. Reporting of country-specific risk factors with their geographical variations was also sparse. CONCLUSION Overall, the cancer epidemiology literature from India is sparse. More studies with robust designs representing all parts of the country are currently needed.

Abstract
BACKGROUND A breast cancer biobank with retrospectively collected patient data and FFPE tissue samples was established in 2018 at Prashanti Cancer Care Mission, Pune, India. It runs a cancer care clinic with support from a single surgeon's breast cancer practice. The clinical data and tissue sample collection is undertaken with appropriate patient consent following ethical approval and guidelines. METHODS The biobank holds clinical history, diagnostic reports, treatment and follow-up information along with FFPE tumor tissue specimens, adjacent normal and, in few cases, contralateral normal breast tissue. Detailed family history and germline mutational profiles of eligible and consenting patients and their relatives are also deposited in the biobank. RESULTS Here, we report the first audit of the biobank. A total number of 994 patients with breast disease have deposited consented clinical records in the biobank. The majority of the records (80%, n = 799) are of patients with infiltrating ductal carcinoma (IDC). Of 799 IDC patients, 434 (55%) have deposited tumor tissue in the biobank with consent. In addition, germline mutation profiles of 84 patients and their family members are deposited. Follow-up information is available for 85% of the 434 IDC patients with an average follow-up of 3 years. CONCLUSION The biobank has aided the initiation of translational research at our center in collaboration with eminent institutes like IISER Pune and SJRI Bangalore to evaluate profiles of breast cancer in an Indian cohort. The biobank will be a valuable resource to the breast cancer research community, especially to understand South Asian profiles of breast cancer.

Abstract
BACKGROUND Pancreaticoduodenectomy (PD) is more challenging in the elderly. METHODS Data of patients undergoing PD above 70 years of age was analysed to study short and long-term outcomes along with the quality of life parameters (QOL). RESULTS Out of 1271 PDs performed, 94 (7%) patients were 70 years or more. American Society of Anaesthesiology (ASA) scores were higher in comparison to patients below 70 years (ASA 1;20% vs. 54% and ASA 2&3;80% vs. 46%, p < 0.001). The postoperative 90-day mortality rate of 5.3% and morbidity (Clavein Grade III and IV of 27%) was higher but non-significant compared to 3.9% (p = 0.50) and 20% (p = 0.11) in patients less than 70 years. The median survival of 40 months was significantly better for periampullary carcinoma when compared to 15 months in pancreatic ductal adenocarcinoma (PDAC) (p < 0.0001). Patients, less than 70 years had significantly better 3-year survival; 64% vs 43% with periampullary etiology (p < 0.01) and 29% vs 0% with PDAC (p < 0.0001). QLQ-PAN 26 questionnaire responses were suggestive of good long term QOL in these patients. CONCLUSION Although PD is safe and feasible in the elderly population with good long-term QOL, postoperative morbidity and mortality can be slightly higher and long-term survival significantly lower.

Abstract
Background and Objectives Hospital-based cancer registry is an essential tool for augmentation of the standard of care, administration motive, and resource for population-based cancer registries. Here, we presented hospital-based brain tumor registry (HBBTR) to outline a comprehensive epidemiological data, both clinical and histopathological, as well as trends of central nervous system tumors. In addition, we compare this data with national brain tumor data as well as an international brain tumor registry. Materials and Methods For the generation of this 7-year HBBTR data of all primary intracranial tumors operated, diagnosed, and registered at the Department of Pathology, Sawai ManSingh, between January 1, 2013 and December 31, 2019, was collected, analyzed, and compared with Tata Memorial Hospital, National Institute of Mental Health and Neurosciences, and Central Brain Tumor Registry of the United States. Results A total of 3,526 patients were of primary intracranial tumors. Out of which, male patients were 1,982 (56.2%), while 1,544 (43.8%) were female patients. Maximum proportion of tumors was in fifth decade. Overall, pediatric and adult patients constituted of 15.5 and 84.5% of the cases, respectively. Among all primary intracranial tumors, meningiomas (20%) were most common followed by glioblastoma multiformat (18%) and least common were germ cell tumors (0.1%) followed by pineal tumors (0.3%). In pediatric cohort astrocytic tumors (30.1%) are most common followed by embryonal tumors (20.8%), while in adults meningiomas (23.1%) were most common followed by glioblastomas (20.3%). Our registry showed similar trends of tumors with national data as compared with international data in median age of presentation. Conclusion This HBBTRs provide prevalence of primary intracranial tumors at a tertiary care center and could be a part of population-based registry.

Abstract
Background The etiopathogenesis and diagnosis of cancer has intrigued modern oncology researchers for decades, and it is still a rapidly growing area in medicine. Cancer is not a single disease, but rather a collection of related diseases which is diagnosed on the basis of aberrant cellular changes. Since this is established by the modern medical science, it becomes important to understand it from the perspective of Ayurveda. Despite the fact that there are a few endeavors in this area, there is no common agreement among the experts. The current article is an effort to fulfill this knowledge gap. Aims and objectives To understand the cancer systematically in the frame work of Ayurveda and propose its probable Samprapti (pathogenic process) based on clinical observations. Materials and methods It is based on the clinical observation and detailed examination of 400 cancer patients, following modern and Ayurvedic methods in an institution dedicated to oncology. Results After careful study of each type of cases of cancer at its all stages to understand the natural history and clinical behavior, Ayurvedic pathogenesis, diagnosis with possible etiologic association has been arrived at. Three main conditions, namely Udara (enlargement of abdomen), Gulma (lump in abdomen) and Vidradhi (abscess) can be equated with cancer. Conclusion Modern diagnosis of cancer cannot be equated with any single disease entity mentioned in the Ayurvedic literature. Udara-Gulma-Vidradhi is the abdominal tumors present as benign and possess cancerous potential.

Abstract
INTRODUCTION Oral cancer is common cancer in many low- and middle-income countries (LMICs) with a low five-year survival rate. It is among the four most common types of cancer in South East Asia region. In South-Central Asia, lip and oral cavity cancer is the second most common cancer according to the specific cancer types. METHODS This scoping review intended to investigate published studies on the current prevalence and incidence of oral cancer in LMICs. The review was conducted applying the search words "Oral Cancer" and "Mouth neoplasm" as the Medical Subject Heading (MeSH) major topic and "Epidemiology" and ("prevalence" OR "incidence") as the MeSH subheading; the search was supplemented by cross-references. Included studies met the following criteria: original studies, reporting of prevalence or incidence rates, population-based studies, studies in English language and studies involving humans. RESULTS The sample sizes ranged from 486 to 101,761 with 213,572 persons included. Buccal mucosa is one of the most common sites of oral cancer, associated with the widespread exposure to chewing tobacco. The incidence is likely to rise in the region where gutkha, pan masala, pan-tobacco and various other forms of chewing tobacco are popular. CONCLUSION This review contributes to useful information on prevalence and incidence estimates of oral cancer in LMICs.

Genetic variants of DNAH11 and LRFN2 genes and their association with ovarian and breast cancer. Int J Gynaecol Obstet 2019; 148:118-122. [PMID: 31605628 DOI: 10.1002/ijgo.12997] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/05/2018] [Revised: 05/11/2019] [Accepted: 10/11/2019] [Indexed: 01/13/2023]
Abstract
OBJECTIVE To investigate the association of newly identified genetic variants G>A (rs2285947) of the DNAH11 gene and G>A (rs2494938) of the LRFN2 gene with ovarian and breast cancers in women belonging to Jammu and Kashmir state, where the prevalence of ovarian and breast cancers is remarkably high in the population. METHODS A candidate gene prospective case-control association study design was adopted, in which 354 cases (219 cases of ovarian cancer and 135 cases of breast cancer) were histopathologically confirmed and 330 healthy controls matched for age and ethnicity were recruited. The details of cases and controls were also recorded in a predesigned pro forma after their written informed consent. Both variants were genotyped by TaqMan allele discrimination assay using real-time polymerase chain reaction. Logistic regression analysis was performed to estimate the corrected odds ratio (OR), confidence interval (CI), and level of significance (P value) for potential confounding factors. RESULTS The rs2285947 variant of DNAH11 was found to be significantly associated with both ovarian and breast cancers with adjusted ORs of 1.7 (95% CI 1.2-2.4; P=0.004) and 1.70 (95% CI 1.13-2.54; P=0.0009), respectively. However, no significant association of variant rs2494938 of LRFN2 was observed with ovarian cancer (estimated OR 0.9, 95% CI 0.6-1.4; P=0.919) or breast cancer (estimated OR 1.27, 95% CI 0.8-1.9; P=0.216). CONCLUSIONS The collected data proposed that the variant rs2285947 of DNAH11 gene is a potential risk factor for ovarian and breast cancers in the studied population.

Abstract
OBJECTIVES To identify and summarise all studies using statistical methods to project lung cancer incidence or mortality rates more than 5 years into the future. STUDY TYPE Systematic review. METHODS We performed a systematic literature search in multiple electronic databases to identify studies published from 1 January 1988 to 14 August 2018, which used statistical methods to project lung cancer incidence and/or mortality rates. Reference lists of relevant articles were checked for additional potentially relevant articles. We developed an organisational framework to classify methods into groups according to the type of data and the statistical models used. Included studies were critically appraised using prespecified criteria. RESULTS One hundred and one studies met the inclusion criteria; six studies used more than one statistical method. The number of studies reporting statistical projections for lung cancer increased substantially over time. Eighty-eight studies used projection methods, which did not incorporate data on smoking in the population, and 16 studies used a method which did incorporate data on smoking. Age-period-cohort models (44 studies) were the most commonly used methods, followed by other generalised linear models (35 studies). The majority of models were developed using observed rates for more than 10 years and used data that were considered to be good quality. A quarter of studies provided comparisons of fitted and observed rates. While validation by withholding the most recent observed data from the model and then comparing the projected and observed rates for the most recent period provides important information on the model's performance, only 12 studies reported doing this. CONCLUSION This systematic review provides an up-to-date summary of the statistical methods used in published lung cancer incidence or mortality projections. The assessment of the strengths of existing methods will help researchers to better apply and develop statistical methods for projecting lung cancer rates. Some of the common methods described in this review can be applied to the projection of rates for other cancer types or other non-infectious diseases.

Abstract
The incidences of cancer are continuously increasing worldwide, affecting life of millions of people. Several factors associated with the internal and external environment are responsible for this deadly disease. The key internal determinants like abnormal hormonal regulation, genetic mutations and external determinants such as lifestyle and occupational factors enhances onset of cancer. From the ancient time, plants were remained as the most trusted source of medicine for the treatment of diverse disease conditions. Extensive studies have been performed for the discovery of effective anticancer agent from the plant and still it is going on. Pentacyclic triterpenoids are biologically active phytochemicals having a different range of activities such as anti-inflammatory, hepatoprotective, anti-hypertensive, antiulcerogenic and anti-tumor. These compounds generally contain ursane, oleanane, lupane and friedelane as a chief skeleton of pentacyclic triterpenoids which are generally present in higher plants. Isoprene unit, phytochemical, with good antitumor/anticancer activity is required for the biosynthesis of pentacyclic triterpenoids. Mechanisms such as cytotoxicity, DNA polymerase inhibition, regulation of apoptosis, change in signal transductions, interfere with angiogenesis and dedifferentiation, antiproliferative activity and metastasis inhibition are might be responsible for their anticancer effect. Present review spotlights diverse targets, mechanisms and pathways of pentacyclic triterpenoids responsible for anticancer effect.

Abstract
There is paucity in the literature regarding gallbladder cancer in Saudi Arabia. Only 3% of gallbladder cancers worldwide are primary squamous cell carcinoma (SCC). We present the first case of primary gallbladder SCC reported in Saudi Arabia. Physicians should be aware of this cancer even if it is rare in our country. We should consider gallbladder cancer when diagnosing gallbladder-related symptoms.
Introduction Primary squamous cell carcinoma of the gallbladder is extremely rare, and accounts for about 3% of all malignant gallbladder neoplasms. Presentation of case We report the case of a 58-year-old woman who presented with acute onset epigastric pain radiating to the back. The initial diagnosis, based on radiological images, was an incidental gallbladder mass with multiple gallstones. A staging laparoscopy was performed, followed by exploratory laparotomy with radical cholecystectomy. Segments 4b and 5 of the liver and the first part of the duodenum with the transverse colon were also resected. Histopathology of the gallbladder mass revealed invasive moderately differentiated squamous cell carcinoma with infiltration of liver segments 4b and 5, the first part of the duodenum, and two pericaval lymph nodes (with lymphovascular and perineural invasion). The primary tumour was scored as pT3, pN2, M1, stage IVB, based on the American Joint Committee on Cancer classification, version 7. The patient was discharged postoperatively and started adjuvant chemotherapy. Discussion The best option for treating early-stage gallbladder cancer is radical surgery, while adjuvant chemo-radiation can also be beneficial. Our patient did not exhibit the typical symptoms of gallbladder cancer, and radiography was required for her diagnosis. Thus, additional work is needed to improve the detection of squamous cell carcinoma to improve the prognosis of patients like our own. Conclusion Clinicians must be alert to the possibility of squamous cell gallbladder carcinoma, and gallbladder neoplasms should be among the possibilities considered during the differential diagnosis of symptoms related to the gallbladder.

Abstract
Breast carcinogenesis is a multistep process, involving both genetic and epigenetic modification process of genes, involved in diverse pathways ranging from DNA repair to metabolic processes. This study was undertaken to assess the role of promoter methylation of GSTP1 gene, a member of glutathione-S-transferase family of enzymes, in relation to its expression, polymorphism, and clinicopathological parameters. Tissue samples were taken from breast cancer patients and paired with their normal adjacent tissues. A total of 51 subjects were studied, in which the frequency of promoter methylation in cancerous tissue was 37.25% as against 11% in the normal tissues ( p ≤ 0.001). The hypermethylated status of the gene was significantly associated with the loss of the protein expression ( r = −0.449, p = 0.001, odds ratio = 7.42, 95% confidence interval = 2.05–26.92). Furthermore, when compared with the clinical parameters, the significant association was found between the promoter hypermethylation and lymph node metastasis ( p ≤ 0.001), tumor stage ( p = 0.039), tumor grade ( p = 0.028), estrogen receptor status ( p = 0.018), and progesterone receptor status ( p = 0.046). Our study is the first of its kind in Kashmiri population, which indicates that GSTP1 shows aberrant methylation pattern in the breast cancer with the consequent loss in the protein expression. Furthermore, it also shows that the gene polymorphism (Ile105Val) at codon 105 is not related to the promoter methylation and two are the independent events in breast cancer development.

Abstract
BACKGROUND Punjab state is particularly reporting a rising burden of cancer. A 'door to door cancer awareness and early detection campaign' was therefore launched in the Punjab covering about 2.67 million population, wherein after initial training accredited social health activists (ASHAs) and other health staff conducted a survey for early detection of cancer cases based on a twelve point clinical algorithm. OBJECTIVE To ascertain unit cost for undertaking a population-based cancer awareness and early detection campaign. MATERIALS AND METHODS Data were collected using bottom-up costing methods. Full economic costs of implementing the campaign from the health system perspective were calculated. Options to meet the likely demand for project activities were further evaluated to examine their worth from the point of view of long-term sustainability. RESULTS The campaign covered 97% of the state population. A total of 24,659 cases were suspected to have cancer and were referred to health facilities. At the state level, incidence and prevalence of cancer were found to be 90 and 216 per 100,000, respectively. Full economic cost of implementing the campaign in pilot district was USD 117,524. However, the financial cost was approximately USD 6,301. Start-up phase of campaign was more resource intensive (63% of total) than the implementation phase. The economic cost per person contacted and suspected by clinical algorithm was found to be USD 0.20 and USD 40 respectively. Cost per confirmed case under the campaign was 7,043 USD. CONCLUSIONS The campaign was able to screen a reasonably large population. High to high economic cost points towards the fact that the opportunity cost of campaign put a significant burden on health system and other programs. However, generating awareness and early detection strategy adopted in this campaign seems promising in light of fact that organized screening is not in place in India and in many developing countries.

Abstract
CONTEXT There are no recent authoritative data about incidence and prevalence of various types of cancers in Pakistan. AIM To determine the frequency of malignant tumors seen in our practice and provide a foundation for building a comprehensive cancer care strategy. MATERIALS AND METHODS 10,000 successive cases of solid malignant tumors reported in 2014 were included. All cases had formalin fixed, paraffin embedded specimens available and diagnosis was based on histological examination of H and E stained slides plus ancillary studies at the Section of Histopathology, Department of Pathology and Laboratory Medicine, Aga Khan University Hospital, Karachi. The latest WHO classifications were used along with the latest CAP protocols for reporting and the most updated TNM staging. RESULTS There were 9,492 (94.9%) primary tumors while 508 (5.1%) were metastatic. Some 5,153 (51.5%) were diagnosed in females and 4,847 (48.5%) in males. The commonest malignant tumors in females were breast (32%), esophagus (7%), lymphomas (6.8%), oral cavity (6.7%) and ovary (4.8%), while in males they were oral cavity (13.9%), lymphomas (12.8%), colorectum (7.9%), stomach (6.9%) and esophagus (6.6%). Malignant tumors were most common in the 5th, 6th and 7th decades. About 8% were seen under 20 years of age. CONCLUSIONS Oral cavity and gastrointestinal cancers continue to be extremely common in both genders. Breast and esophageal cancers are prevalent in females. Lung and prostate cancer are less common than in the west. Ovarian cancer was very common but cervix cancer was less so.

Abstract
BACKGROUND Lung cancer has been a major health problem in developed countries for several decades, and has emerged recently as the leading cause of cancer death in many developing countries. The incidence of lung cancer appears to be increasing more rapidly in rural than in urban areas of China. This paper presents the trends of lung cancer incidence and survival derived from a 40-year population-based cancer monitoring program in a rural area, Qidong, China. MATERIALS AND METHODS The Qidong cancer registration data of 1972- 2011 were used to calculate the crude rate, age-standardized rate by Chinese population (CASR) and by world population (WASR), birth cohort rates, and other descriptive features. Active and passive methods were used to construct the data set, with a deadline of the latest follow-up of April 30, 2012. RESULTS The total number of lung cancer cases was 15,340, accounting for 16.5% of all sites combined. The crude incidence rate, CASR and WASR of this cancer were 34.1, 15.7 and 25.4 per 100,000, respectively. Males had higher crude rates than females (49.7 vs 19.0). Rapidly increasing trends were found in annual percent change resulting in lung cancer being a number one cancer site after year 2010 in Qidong. Birth cohort analysis showed incidence rates have increased for all age groups over 24 years old. The 5 year observed survival rates were 3.55% in 1973-1977, 3.92 in 1983-1987, 3.69% in 1993-1997, and 6.32% in 2003-2007. Males experienced poorer survival than did females. CONCLUSIONS Lung cancer has become a major cancer-related health problem in this rural area. The rapid increases in incidence likely result from an increased cigarette smoking rate and evolving environmental risk factors. Lung cancer survival, while showing some improvement in prognosis, still remains well below that observed in the developed areas of the world.

Abstract
Lung cancer is the leading contributor to cancer deaths in the developing world. Within countries, significant variability exists in the prevalence of lung cancer risk, yet limited information is available whether some of the observed variability is associated with differences in the consumption pattern of local tobacco products with differing potency. We recruited 606 lung cancer cases and 606 controls from the B.P. Koirala Memorial Cancer Hospital in Nepal from 2009-2012. We estimated odds ratios (ORs) and 95% confidence intervals (CI) for lung cancer risk associated with different tobacco products, using unconditional logistic regression. Unfiltered cigarettes tended to be the most frequently used products across ethnic subgroup with about 53.7% of Brahmins, 60.1% of Chettris, and 52.3% of Rai/Limbu/Magar/others. In contrast, about 39.9% of Madishe/Tharu smokers reported using bidi compared with only 27.7% who smoked unfiltered cigarettes. Among those who only smoked one type of product, choor/kankat smokers had the highest lung cancer risk (OR 10.2; 95% CI 6.2-16.6), followed by bidi smokers (OR 5.6; 95% CI 3.6-8.7), unfiltered cigarettes (OR 4.9; 95% CI 3.4-7.2), and filtered cigarettes (OR 3.4; 95% CI 2.2-5.3). A clear dose-response relationship was observed between increased frequency of smoking and lung cancer risk across all ethnic subgroups. These results highlight the important role of traditional tobacco products on lung cancer risk in the low income countries.

Abstract
In view of funding crunches and inadequate manpower in cytology in developing countries like India, single lifetime screening for cervical cancer has been suggested. In this study, an attempt was made to identify high risk groups of women for this screening to make it more effective for early detection. Cytological data were derived from the ongoing routine cervical cytology screening program for women attending Gynaecology Out Patient Department of Queen Mary's Hospital of K.G.Medical University, Lucknow, India during a span of 35 years (April 1971 - December 2005). Cervical smears in a total of 38,256 women were cytologically evaluated. The frequencies of squamous intraepithelial lesions of cervix (SIL) and carcinoma cervix were found to be 7.0% and 0.6%, respectively, in the series. Predisposing factors related to cervical carcinogenesis were analyzed in detail to establish the most vulnerable groups of women for single life time screening. The incidence of SIL and carcinoma cervix was found to be maximal in women above the age of 40 years irrespective of parity and in multiparous women (with three or more children) irrespective of age. The incidence of cervical cytopathologies was significantly higher in symptomatic women, the frequency of SIL being alarmingly higher in women complaining of contact bleeding and that of carcinoma cervix in older women with postmenopausal bleeding. It is consequently felt that single life time screening must include the three groups of women delineated above. Such selective screening appears to be the most economical, cost effective and feasible approach to affordably control the menace of cervical cancer in developing countries like India.

Abstract
BACKGROUND A very high incidence of lung cancer is observed in Mizoram and Manipur, North East India. We conducted a population based case control study to establish associations of p53 codon 72 polymorphisms and interactions with environmental factors for this high incidence. MATERIAL AND METHODS A total of 272 lung cancer cases and 544 controls matched for age (±5 years), sex and ethnicity were collected and p53 codon 72 polymorphism genotypes were analyzed using a polymerase chain based restriction fragment length polymorphism assay. We used conditional multiple logistic regression analysis to calculate adjusted odds ratios and 95% confidence intervals after adjusting for confounding factors. RESULTS p53 Pro/Pro genotype was significantly associated with increased risk of lung cancer in the study population (adjusted OR=2.14, CI=1.35-3.38, p=0.001). Interactions of the p53 Pro/Pro genotype with exposure to wood smoke (adjusted OR=3.60, CI=1.85-6.98, p<0.001) and cooking oil fumes (adjusted OR=3.27, CI=1.55-6.87, p=0.002), betel quid chewing (adjusted OR=3.85, CI=1.96- 7.55, p<0.001), tobacco smoking (adjusted OR=4.42, CI=2.27-8.63, p<0.001) and alcohol consumption (adjusted OR=3.31, CI=1.10-10.03, p=0.034) were significant regarding the increased risk of lung cancer in the study population. CONCLUSIONS The present study provided preliminary evidence that a p53 codon 72 polymorphism may effect lung cancer risk in the study population, interacting synergistically with environmental factors.

Abstract
BACKGROUND Cancer is a major cause of mortality in developing countries and correct and valid information about the epidemiology of this disease is the first step in the planning of health care in each region. The aim of this study was to determine the relative frequency, mean age and sex ratio of the most 10 common non-skin cancers in the world and Iran, among patients referred to an oncology clinic. MATERIALS AND METHODS This descriptive study was conducted in Mashhad, north east of Iran. The data obtained from the records of patients referred to the private oncology center between the years of 1985-2012." According to the latest report of GLOBOCAN study commonest malignancies included were lung, breast, colorectal, prostate, stomach, liver, cervix, esophageal, bladder cancers and Non-Hodgkin lymphoma. RESULTS A total of 4,606 cases were analyzed. The mean age was 55.5±13.8years (male: 59.5±13.9, female: 52.6±12.9). Overall, breast cancer (1,264 cases, relative frequency of 27.4%) was the most prevalent cancer; however the mean ages of diagnosis were not significantly different between 5-year time period divisions (p=0.290). The most common cancer in men was esophageal cancer (26.3%).The lowest mean age was related to women diagnosed with breast cancer (48.5±11.8) and men with non-Hodgkins lymphoma (48.4±17.8). There were statistically significant differences between the mean age of men and women with gastric (p=0.003) and esophageal cancers (p<0.001). Male to female sex ratios in our study for bladder, lung and stomach cancers were 6.57, 2.60 and 2.50 respectively. CONCLUSIONS The results showed that breast cancer tends to be found in younger female patients and bladder cancer appears more often in men. Screening in target population in addition to early diagnosis may reduce death and disability.

[PMID: 26581132 DOI: 10.1016/j.ijrobp.2015.08.009] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/22/2015] [Revised: 07/30/2015] [Accepted: 08/04/2015] [Indexed: 11/24/2022]
Abstract
PURPOSE To conduct a survey of radiation oncologists in India, to better understand specific educational needs of radiation oncology in India and define areas of collaboration with US institutions. METHODS AND MATERIALS A 20-question survey was distributed to members of the Association of Indian Radiation Oncologists and the Indian Brachytherapy Society between November 2013 and May 2014. RESULTS We received a total of 132 responses. Over 50% of the physicians treat more than 200 patients per day, use 2-dimensional or 3-dimensional treatment planning techniques, and approximately 50% use image guided techniques. For education needs, most respondents agreed that further education in intensity modulated radiation therapy, image guided radiation therapy, stereotactic radiation therapy, biostatistics, and research methods for medical residents would be useful areas of collaboration with institutions in the United States. Other areas of collaboration include developing a structured training module for nursing, physics training, and developing a second-opinion clinic for difficult cases with faculty in the United States. CONCLUSION Various areas of potential collaboration in radiation oncology education were identified through this survey. These include the following: establishing education programs focused on current technology, facilitating exchange programs for trainees in India to the United States, promoting training in research methods, establishing training modules for physicists and oncology nurses, and creating an Indo-US. Tumor Board. It would require collaboration between the Association of Indian Radiation Oncologists and the American Society for Radiation Oncology to develop these educational initiatives.

Abstract
Cervical cancer is one of the leading causes of cancer in women worldwide. One way by which the incidence of this malignant disease can be minimized is by imparting knowledge through health education. This study aimed at developing an educational package on cervical cancer (EPCC) and determining its effectiveness in terms of significant increase in knowledge of rural women regarding cervical cancer. A one group pre-test, post-test design was adopted. Thirty rural women were selected using a convenient sampling method. Data were collected using a demographic questionnaire and a structured knowledge questionnaire developed by the researchers. The EPCC was designed for a duration of one hour and 10 minutes. The structured knowledge questionnaire was first administered as the pre-test, following which knowledge on cervical cancer was imparted using the EPCC. On the 8th day, the post-test was administered. Data were analyzed using descriptive and inferential statistics. The mean post-test knowledge score of the women regarding cervical cancer was significantly higher than that of their mean pre-test score, indicating that the EPCC was effective in improving the knowledge of rural women on cervical cancer. The association between pre-test knowledge scores and selected demo-graphic variables were computed using chi-square test showed that pre-test knowledge score of the women regarding cervical cancer was independent of all the socio-demographic variables. It was concluded that the EPCC is effective in improving the knowledge of women, regarding cervical cancer. Since the prevalence of cervical cancer is high, there is an immediate need to educate women on prevention of cervical cancer.

Abstract
Cancer is one of the most feared diseases globally and there has been a sustained rise in its incidence in both developing and developed countries. Despite the growing therapeutic options for patients with cancer, their efficacy is time-limited and non-curative. Hence to overcome these drawbacks, an incessant screening for superior and safer drugs has been ongoing for numerous decades, resulting in the detection of anti-cancer properties of several phytochemicals. Chemoprevention using readily available natural substances from vegetables, fruits, herbs and spices is one of the significantly important approaches for cancer prevention in the present era. Among the spices, Crocus sativus L. (saffron; fān hóng huā) has generated interest because pharmacological experiments have established numerous beneficial properties including radical scavenging, anti-mutagenic and immuno-modulating effects. The more powerful components of saffron are crocin, crocetin and safranal. Studies in animal models and with cultured human malignant cell lines have demonstrated antitumor and cancer preventive activities of saffron and its main ingredients. This review provides a brief insight into the anticancer properties of saffron and its components.

Abstract
BACKGROUND A case-control study was conducted to evaluate the effect of household exposure, dietary habits, smoking and Glutathione S-Transferases M1, T1 polymorphisms on lung cancer among women in Mizoram, India. MATERIALS AND METHODS We selected 230 newly diagnosed primary lung cases and 460 controls from women in Mizoram. Multivariate logistic regression analysis was performed to estimate adjusted odds ratio (OR). RESULTS Exposure of cooking oil fumes (p<0.003), wood as heating source for cooking (p=0.004), kitchen inside living room (p=0.001), improper ventilated house (p=0.003), roasting of soda in kitchen (p=0.001), current smokers of tobacco (p=0.043), intake of smoked fish (p=0.006), smoked meat (p=0.001), Soda (p<0.001) and GSTM1 null genotype (p=0.003) were significantly associated with increased risk of lung cancer among women in Mizoram. Significantly protective effect was observed for intake of bamboo shoots (p=<0.001) and egg (p<0.001). A clear increase in dose response gradient was observed for total cooking dish years. Risk for lung cancer tends to increase with collegial effect of indoor environmental sources (p=0.022). Significant correlation was also observed for interaction of GST polymorphisms with some of dietary habits. CONCLUSIONS We confirmed the important role of exposure of cooking oil emission and wood smoke, intake of smoked meat, smoked fish and soda (an alkali preparation used as food additives in Mizoram) and tobacco consumption for increase risk of lung cancer among Women in Mizoram.

Abstract
PURPOSE The aim of this study was to investigate the prognostic significance of the CD56+NK-TIL count in infiltrating ductal carcinoma (IDC) of breast. MATERIAL AND METHODS Immunohistochemistry (IHC) was performed using antibodies specific for CD56 on formalin-fixed and paraffin-embedded tissue sections of 175 infiltrating ductal carcinomas (IDC) of breast. Distribution of intratumoral and stromal CD56+NK-TILs was assessed semi-quantitatively. RESULTS A low intratumoral CD56+count showed significant and inverse associations with tumor grade, stage, and lymph node status, whereas it had significant and direct association with response to treatment indicating good prognosis. These patients had better survival (χ2=4.80, p<0.05) and 0.52 fold lower death rate (HR=0.52, 95% CI=0.28-0.93) as compared to patients with high CD56+ intratumoral count. The association of survival was insignificant with low CD56 stromal count as compared to high CD56 stromal count (χ2=1.60, p>0.05). CONCLUSION To conclude, although NK-TIL count appeared as a significant predictor of prognosis, it alone may not be sufficient for predicting the outcome considering the fact that there exists a crosstalk between NK-TILs and the other immune infiltrating TILs.

Abstract
We attempted to develop an indicator combining incidence and mortality (summary indicator of cancer burden, SMCB) and to compare the magnitudes of cancer burden by world region. The SMCB was used to measure the size of cancer burden summarizing the incidence and mortality. The incidence and mortality were divided in equivalent forms and were split. The criteria dividing the size of cancer burden were used as the maximum incidence and mortality by men and women according to the world database, and the value corresponding to 10% of each maximum was set as the cut-off value. In SMCB, the size of cancer burden was highest for men with lung cancer (SMCB=18) and for women with breast cancer (SMCB=14) in MDR (more developed regions) compared to the size of burden in LDR (lower developed regions) (lung, SMCB=11, breast, SMCB=8). For men, the size of cancer burden by region was highest in EURO (SMCB=18, lung), followed by WPRO (SMCB=16, lung), PAHO (SMCB=14, prostate), AFRO (SMCB=8, prostate) and SEARO (SMCB=7, lung). Moreover, for women, the size of cancer burden was greatest in EURO (SMCB=14, breast), followed by PAHO (SMCB=13, breast), AFRO (SMCB=11, cervix uteri), EMRO (SMCB=9, breast) or SEARO (SMCB=8, cervix uteri) and WPRO (SMCB=7, lung). The summary indicator will help to provide a priority setting for reducing cancer burden in health policy.

Abstract
Computed Tomography Colonography (CTC) is a medical imaging technology used in identifying polyps and colon cancer masses in the large intestine. The technique has evolved a great deal since its invention and has become a routine diagnostic procedure in Western countries due to its non invasiveness and ease of use. The objective of our study was to explore the possibility of CTC application in Indian hospitals. This paper gives an overview of the procedure and its commercial viability. The explanation begins with the domain aspects from gastroenterologist perspective, the new way of thinking in polyp classification, the technical components of CTC procedure, and how engineering solutions have helped clinicians in solving the complexities involved in colon diagnosis. The colon cancer statistics in India and the results of single institution study we carried out with retrospective data is explained. By considering the increasing number of patients developing colon malignancies, the practicality of CTC in Indian hospitals is discussed. This paper does not reveal any technical aspects (algorithms) of engineering solutions implemented in CTC.
