Abstract
BACKGROUND An increasing incidence of colorectal cancer (CRC) is being reported in developing countries, including India. Most Indian studies on CRC are retrospective and single-centered. The present study is an attempt to understand the current clinical profile and stage of newly diagnosed CRCs across multiple centers in Tamil Nadu, India. METHODS A multi-centric observational survey was conducted between September 1, 2021, and August 31, 2022, under the aegis of the Indian Society of Gastroenterology - Tamil Nadu chapter. Patients 18 years of age and older with a recent diagnosis of CRC fulfilling the inclusion criteria were prospectively recruited at the participating centers. Their demographic, clinical, biochemical, endoscopic, histopathologic, radiologic and risk factor details were systematically collected and analyzed. RESULTS Across 23 centers in Tamil Nadu, 1208 patients were recruited. The male:female ratio was 1.49:1, while mean (SD) age was 57.7 (13.5) years. A majority (81.9%) were Tamils and 78.5% belonged to lower socioeconomic classes. The predominant symptoms were hematochezia (30.2%) and a change in bowel habits (27.5%). The most common locations were the rectum (34.3%) and rectosigmoid (15.1%). Synchronous CRCs were seen in 3.3% and synchronous colorectal polyps in 12.8%. Predisposing factors for CRC were seen in 2%. A past history of any cancer among CRC patients was obtained in 3.1% and a family history of any cancer was found in 7.6%. Patients who were either overweight or obese constituted 46.4% of the study population. At presentation, the predominant stages were stage III (44.7%) and stage IV (20.8%). CONCLUSIONS A majority of patients with newly diagnosed CRC in Tamil Nadu belonged to the lower socioeconomic classes. About 60% had CRCs located within the reach of the flexible sigmoidoscope. Two-thirds of the patients exceeded stage II disease at presentation. TRIAL REGISTRATION Not applicable.

Abstract
BACKGROUND Current cancer treatments include surgery, radiotherapy, chemotherapy, and immunotherapy. Despite these treatments, a main issue in cancer treatment is early detection. microRNAs (miRNAs) can be used as markers to diagnose and treat cancers. This study investigated the effect of radiotherapy on miR-374 expression, and APC and GSK-3β, two of its target genes, in the WNT pathway, in peripheral blood samples from radiotherapy-treated colorectal cancer (CRC) patients. METHODS Peripheral blood was collected from 25 patients before and after radiotherapy. RNA was extracted from the blood and cDNA synthesized. miR-374, APC, and GSK-3β expression was determined by real-time polymerase chain reaction (RT-PCR) and the amplicons were sequenced. Finally, the data were statistically evaluated. RESULTS Quantitative RT-PCR revealed significant down-regulation of miR-374 (0.63-fold) and up-regulation of APC (1.12-fold) and GSK-3β (1.22-fold) in CRC patients after five weeks of radiotherapy. Sequencing of PCR-produced amplicons confirmed the conservation of mature and precursor sequences encoding miR-374. miR-374 expression changed with time after radiotherapy treatment and related tumor grading. Increased age and tumor grade positively correlated with decreased miR-374 expression. CONCLUSION miR-374 expression, and that of its two target genes, APC and GSK-3β, changed after radiotherapy. These genes can likely be used as diagnostic radiotherapy markers in CRC.

Abstract
Introduction: Colorectal cancer is the third most common cancer in men and the second in women worldwide. The objective of the present study was to determine and quantify important modifiable risk factors attributable to colorectal cancer, in order to explore the ways to reduce the incidence of colorectal cancer in this region. Materials and Methods: A case–control study was conducted at a tertiary care hospital in Goa, India. The study subjects were group matched for age and sex so as to include 110 cases and 110 controls. Only incident cases of colorectal cancer were recruited in the study. Predesigned structured questionnaire was utilized for data collection, while anthropometric measurements and laboratory investigations were conducted. Statistical analysis was conducted using SPSS software package. The study was approved by the Institutional Ethics Committee of the institute. Informed written consent was obtained from the study participants. Results: Smoking, smokeless tobacco use, alcohol consumption, red meat consumption, high body mass index (BMI), and the presence of Type 2 diabetes mellitus were found to be the risk factors for colorectal cancer on univariate analysis, while fruit and vegetable consumption were found to be the protective factors. Multiple logistic regression analysis identified Type 2 diabetes mellitus and high BMI as risk factors for colorectal cancer and consumption of fruits and vegetables as protective factors. Conclusion: Identification of risk factors for colorectal cancer would help in setting of colorectal cancer screening guidelines as well as for creating awareness regarding prevention of colorectal cancer among the general population.

Abstract
Background: A variety of colorectal lesions are surgically treated encompassing both benign and malignant polyps and colorectal cancer (CRC). CRC is the third most common cause of death in developed countries. Over the last decade, CDX2 has been linked to CRC progression, with reduced expression of the protein associated with more advanced tumor stage, vessel invasion, and metastasis. Aims and Objectives: To analyze the histopathology and immunohistochemistry (IHC) of CDX2 and Ki67 with their expression pattern; in different lesions of colon and rectum with special reference to various grade/stage/histological variants of CRC and to find out whether they can be used as possible predictive marker. Materials and Methods: The study conducted was hospital based, both retrospective and perspective type comprising colorectal samples of total 367 cases (N) within a period of 2½ years. Surgical samples were collected, then grossed, processed, stained with routine hematoxylin and eosin stain in our department followed by IHC of CDX2 and Ki67 in only 60 randomly selected cases (n = 60). Results: Out of total 367 cases, 265 cases were prospective study and 102 cases were retrospective study (240 cases were colonic lesions, and 127 are rectal lesions). The samples included were both from colonoscopy biopsy (small) 319 cases and 48 colectomy specimen (large). Mean age of the study participants was 49.62 years with a standard deviation of 17.34 years and predominantly male, but the difference was not statistically significant (P > 0.05). Colon (238 cases, 64.9%) as a whole affected more than rectum and left sided tumors more than the right side. All 60 cases were found to be positive for CDX2 expression (i.e., 100%); majority (n = 38) being carcinoma cases possessing high score and was statistically significant (P = 0.008, using Chi-square test) indicating strong association, whereas Ki-67 showed an increased index from noneoplastic to neoplastic cases. Conclusion: These markers can be used as future predictive biomarkers which will precisely evaluate risk group, prognosis, and response to therapy hence can be used as target therapy reducing irrational treatment.

Indian J Surg Oncol 2021; 12:454-459. [PMID: 34658570 PMCID: PMC8490567 DOI: 10.1007/s13193-021-01325-5] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/06/2020] [Accepted: 04/15/2021] [Indexed: 12/31/2022] Open
Abstract
OBJECTIVE The clinical profile of colorectal cancers (CRC) in India is different from that described in western countries. Microsatellite instability and APC mutation explain the molecular biology of up to 50% of colorectal cancers. Global genome hypermethylation may be the cause in at least 20% of cases. Few studies from India have examined the epigenetic profile of colorectal cancers. This study was designed to study aberrant promoter hypermethylation of two select tumour suppressor genes (p16, RASSF1a) in patients with colorectal cancer and their association with clinicopathologic features. METHODS A total of 41 samples including controls were collected from colorectal cancer patients. DNA was isolated from tumour tissue, and methylation-specific PCR was performed for the 2 genes. RESULTS p16 and RASSF1a promoter hypermethylation was found in 26% and 48% of CRC cases, respectively. RASSF1a promoter hypermethylation was more often seen in young CRC patients aged 40 years or less, and this was found to be statistically significant (p value = 0.037). CONCLUSION RASSF1a hypermethylation is peculiar to rectal cancers and left-sided colonic tumours in young patients. Large-scale population-based studies with extensive genetic and epigenetic characterization are required for a better understanding and further validation of our findings. For individuals diagnosed with sporadic CRC, these studies on specimen might help predict prognosis and response to therapy.

Abstract
Background No data exist for the long-term outcome of metastatic colorectal cancer (mCRC) from the Southern part of Asia. The primary objective of the study is to evaluate the survival outcome of mCRC from an Indian tertiary care center. The study also aims to highlight the treatment pattern practiced and the unique clinico-pathologic characteristics. Methods This is a single-center retrospective observational study done at a large referral tertiary care center in North India. All patients with synchronous or metachronous mCRC who received at least one dose of chemotherapy for metastatic disease, registered between 2003 to 2017 were included. Primary outcome measures were overall survival and progression-free survival and prognostic factors of overall survival. Descriptive analysis was done for the clinicopathological characteristics and treatment patterns. Kaplan Meier method for overall survival and progression-free survival. Cox regression analysis was performed for the determination of the prognostic factors for overall survival. Result Out of 377 eligible patients, 256 patients (68%) had de novo metastatic disease and the remaining 121 (32%) progressed to metastatic disease after initial treatment. The cohort was young (median age, 46 years) with the most common primary site being the rectum. A higher proportion of signet (9%) and mucinous histology (24%). The three common sites of metastasis were the liver, peritoneum, and lung. In the first line, most patients received oxaliplatin-based chemotherapy (70%). Only 12.5% of patients received biologicals in the first-line setting. The median follow-up and median overall survival of study cohort were 17 months and 18.5 months. The factors associated with poor outcome for overall survival on multivariate analysis were ECOG performance status of > 1, high CEA, low albumin, and the number of lines of chemotherapy received (< 2). Conclusion The outcome of mCRC is inferior to the published literature. We found a relatively higher proportion of patients with the following characteristics; younger, rectum as primary tumor location, the signet, and mucinous histology, higher incidence of peritoneum involvement. The routine use of targeted therapies is limited. Government schemes (inclusion of targeted therapies in the Ayushman scheme), NGO assistance, and availability of generic low-cost targeted drugs may increase the availability.

Abstract
Background Colorectal cancer (CRC) is mostly considered a disease of the elderly. But the rate is increasing among young adults and is associated with different clinical patterns. The objective was to study the frequency of CRC in young patients and compare the clinicopathological profile and survival with the older cohort. Methods Five-year (2012-2016) data of the 912 consecutive CRC cases treated at the center were analyzed. Clinical and histopathological characteristics were compared in young (≤40) and older (>40) patients. Descriptive statistics were used for data presentation. Categorical data were compared by the Chi-square test; survival analyses were performed by Kaplan-Meier method. Results In total, 231 (25.3%) and 681 (74.7%) cases were in the young and older age groups, respectively. Male predominance was noted. Young patients presented predominantly in stage III (46%). Majority of the young patients harbored left-sided tumors (75.8% vs 63.7% in old patients, P = 0.001) and rectum was the favored site in young patients (53.7% vs 37%; P < 0.001). Poorly differentiated adenocarcinoma was more common in the young age group (46.88% vs 24.16% in old patients, P < 0.001), also signet-ring cell morphology occurred more often in young patients (11.7% vs 4%, P < 0.001). Survival was inferior in the patients presenting at an advanced stage or with adverse histology or poor tumor grade. However, stage-specific survival showed no significant difference between both groups. Conclusion This study shows that though young CRC patients present with higher stage, aggressive morphology, and predominantly rectal localization, the overall survival and stage-specific survival did not differ significantly from the older patients.

Abstract
Introduction Colorectal cancer is a major cause of morbidity and mortality globally and its incidence is increasing in developing countries. This study determined the incidence, clinical features and the histopathological patterns of colorectal cancer at Komfo Anokye Teaching Hospital (KATH), Kumasi, Ghana. Methods A retrospective review of all colorectal cancer cases over a six year period from (2009-2015) presented to the Surgical and Oncological Department of KATH. Patients' records were retrieved and information on their demographics, clinical and pathological presentations recorded. Results In all, 221 cases of colorectal cancer were identified over the study period. The mean age was 54 ± 16.8 and ranged from 16 to 90 years. Sixteen (7.24%) had family history of cancer and the prevalence of comorbidities was (24.89%). The commonest clinical symptoms presented were weight loss (44.80%), bleeding per rectum (39.82%) and abdominal pain (38.91%) Majority of the patients presented with rectal cancers (48.87%). Microscopically, adenocarcinoma (68.33%) was the most common histopathological type. According to Tumour Node Metastasis (TNM) staging of cancer, majority of the patients 89(40.27%) were identified as being in late stage (TNM Stage III). The overall crude annual incidence was 4.62 per 100000 populations. The age specific standardized incidence rate was 7.93 per 100,000 population Conclusion This study has clearly showed a high incidence in colorectal cancer at KATH, with similar trends in clinico-pathological patterns comparable to that of most African countries. These include predominance of rectal cancers, high incidence among younger people and delayed presentation of the disease at advanced stage.

Abstract
Colorectal cancer (CRC) is a common cancer worldwide with a low reported incidence in India. There is significant geographical variation in the incidence rates, and the presentation may also vary. There are few studies evaluating the clinical profile of CRC in Indian patients. We analyzed a prospective database maintained at the Tata Memorial Hospital, a referral cancer center in Mumbai, of consecutive patients with CRC between August 2013 and August 2014. We captured details regarding the demography, symptoms, pathology, stage, and treatment plan. The aim was to assess the demographic and clinical details of patients with CRC in India and compare it with those of the reported literature. Eight hundred new patients with CRC were seen in the colorectal clinic in one year. The mean age was 47.2 years. Sixty-five percent were males. Patients were symptomatic for an average period of 4 months prior to presentation. The commonest symptoms were rectal bleeding (57%), pain (44%), and altered bowel habits (26%). Thirteen percent of the patients had signet ring tumors. The median CEA (carcinoembryonic antigen) level was 5.8 ng/mL. Most patients had localized or locally advanced disease. Twenty-eight percent of the patients had metastatic disease with liver being the commonest site of metastases (14%) followed by peritoneum and lung. More than half of the patients received treatment with a curative intent. Colorectal cancer in India differs from that described in the Western countries. We had more young patients, higher proportion of signet ring carcinomas, and more patients presenting with an advanced stage. Inadequate access to healthcare and socioeconomic factors may play a role in some of these differences.

Abstract
Background: Colorectal cancer (CRC) is considered a disease of elderly. There has been a steady decrease in the incidence in those aged >50 years, with an alarming increase noted in adults aged <50 years. Subjects and Methods: We retrospectively analyzed 89 patients diagnosed with CRC aged <40 years between the years 2010 and 2014. Their clinical profile, treatment, and outcomes were studied. Results: The median age was 33 years with a male preponderance (56.2%). Most common symptoms were lower gastrointestinal bleed (48.3%) followed by abdominal pain (46.1%). Most common sites were rectum (50.6%) followed by colon. Histology in all was adenocarcinoma. Most tumors were moderately differentiated (54%) and were stage 4 (36%). Most common sites of metastases were liver (46.9%) followed by peritoneum and ovaries. Majority underwent surgery with adjuvant chemotherapy, with/without radiotherapy. Chemotherapy was administered in 70 patients, majority receiving FOLFOX-4 regimen (88.6%). Median survival was 23 months. Survival in early stage[1],[2] was significantly higher than in advanced stages (3 and above), 34 and 19 months (P = 0.0287), in those aged >40 years compared to <40–35 versus 23 months (P = 0.0029), nonmetastatic compared to metastatic disease – 26 versus 14 months (P = 0.00196), and females compared to males – 26 and 18 months (P = 0.0242). There was no significant difference in survival with respect to tumor grade or site of metastases (hepatic versus extrahepatic). Conclusions: Colorectal carcinoma in young seems to be an emerging problem in India. Any young patient presenting with symptoms suggestive of a colonic malignancy should be evaluated promptly and treated aggressively.

Abstract
Rectal cancer is a heterogeneous disease that develops through multiple pathways characterized by genetic and epigenetic alterations. India has a comparatively higher proportion of rectal cancers and early-onset cases. We analyzed genetic (KRAS, TP53 and BRAF mutations, and MSI), epigenetic alterations (CpG island methylation detection of 10 tumor-related genes/loci), the associated clinicopathological features and survival trend in 80 primary rectal cancer patients from India. MSI was detected using BAT 25 and BAT 26 mononucleotide markers and mutation of KRAS, TP53, and BRAF V600E was detected by direct sequencing. Methyl specific polymerase chain reaction was used to determine promoter methylation status of the classic CIMP panel markers (P16, hMLH1, MINT1, MINT2, and MINT31) as well as other tumor specific genes (DAPK, RASSF1, BRCA1, and GSTP1). MSI and BRAF mutations were uncommon but high frequencies of overall KRAS mutations (67.5%); low KRAS codon 12 and a novel KRAS G15S mutation with concomitant RASSF1 methylation in early onset cases were remarkable. Hierarchical clustering as well as principal component analysis identified three distinct subgroups of patients having discrete age at onset, clinicopathological, molecular and survival characteristics: (i) a KRAS associated CIMP-high subgroup; (ii) a significantly younger MSS, CIMP low, TP53 mutant group having differential KRAS mutation patterns, and (iii) a CIMP-negative, TP53 mutated group. The early onset subgroup exhibited the most unfavorable disease characteristics with advanced stage, poorly differentiated tumors and had the poorest survival compared to the other subgroups. Genetic and epigenetic profiling of rectal cancer patients identified distinct subtypes in Indian population.

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.

Abstract
SUMMARY Aims: An increase in incidence of early-onset colorectal cancer (EOCRC) in developing countries, including India, is reported recently; however, systematic analyses of clinico-pathological features and disease prognosis has seldom been undertaken. Materials & methods: We studied clinical data pertaining to 1259 colorectal adenocarcinoma patients from two tertiary cancer centers in south India. Results: Approximately 45% of patients were aged below 50 years and poor grade and late-stage tumors were significantly associated with early disease onset. Although tumor grade and stage significantly influenced disease-free survival independently, significant association between survival and age of onset or tumor location was not detected unlike previous observations. Conclusion: Given the sizeable proportion of EOCRC, implementation of the revised Bethesda guidelines may not be tenable in India. More importantly, the previous observation of EOCRC being significantly associated with poor survival could, in part, be due to a higher proportion of advanced-stage tumors.

Abstract
BACKGROUND The Asia Pacific consensus for colorectal cancer (CRC) recommends that screening programs should begin by the age of 50. However, there have been reports about increasing incidence of CRC at a younger age (i.e. early-onset CRC). Little is known about the features of early-onset CRC in the Vietnamese population. AIM To describe the clinical, endoscopic and pathological characteristics of early-onset CRC in Vietnamese. METHOD A prospective, cross-sectional study was conducted at the University Medical Center from March 2009 to March 2011. All patients with definite pathological diagnosis of CRC were recruited. The early-onset CRC group were analyzed in comparison with the late-onset (i.e.≥50-year-old) CRC group. RESULTS The rate of early-onset CRC was 28% (112/400) with a male-to-female ratio of 1.3. Some 22.3% (25/112) of the patients only experienced abdominal pain and/or change in bowel habit without alarming symptoms, 42.9% (48/112) considering their symptoms intermittent. The rate of familial history of CRC in early-onset group was significantly higher that of the late-onset group (21.4% versus 7.6%, p<0.001). The distribution of CRC lesions in rectum, distal and proximal colon were 51.8% (58/112), 26.8% (30/112) and 21.4% (24/112), respectively; which was not different from that in the late-onset group (χ2, p=0.29). The rates for poorly differentiated tumors were also not significantly different between the two groups: 12.4% (14/112) versus 8.3% (24/288) (χ2, p=0.25). CONCLUSION A high proportion of CRC in Viet Nam appear at an earlier age than that recommended for screening by the Asia Pacific consensus. Family history was a risk factor of early-onset CRC. Diagnosis of early-onset CRC needs more attention because of the lack of alarming symptoms and their intermittent patterns as described by the patients.
