Decadal Trends and Associated Factors of Colorectal Cancer in Kerala Between 2010 and 2021 Among Patients in a Tertiary Hospital-Based Cancer Registry.

Introduction The incidence of colorectal cancer (CRC) has notably risen on a global scale, owing to modifications in lifestyle patterns and the overconsumption of processed food to meet nutritional requirements. Colorectal cancer is among the most common cancers in India, with a significant number of new cases reported annually. The aim of our study is to examine the trends and association of CRC in Kerala between the years 2010-2021 among patients reporting at a tertiary Hospital-Based Cancer Registry (HBCR) in Ernakulam.

Molecular pathogenesis of microsatellite instability-high early-stage colorectal adenocarcinoma in India.

Objectives: The prevalence of microsatellite instability (MSI) subtype among all colon cancers in India is about 30 %, approximately two times more than that of western population suggesting different molecular pathogeneses.

Methods: A analysis-based Pan cancer differential expression (DE) profile was determined in a primary cohort of early-stage CRC (tumor=10, normal=7), and correlated against MSI status. Using RT-PCR, tumor-specific genes were validated in another cohort of MSI-high CRC (n=15).

Gastrointestinal mucormycosis following liver transplantation: lessons learnt.

Gastrointestinal mucormycosis (GIM) is an uncommonly encountered fungal infection following solid-organ transplantation. GIM is known to be associated with immunocompromised states, remains difficult to diagnose and often results in fatal outcomes. It is plausibly the delay in initiation of appropriate treatment strategies that leads to failure of response and patient demise.

A relook at gastroenteropancreatic neuroendocrine tumours as per 2019 WHO classification-A tertiary centre experience.

Introduction: Neuroendocrine neoplasm of GIT (gastrointestinal tract) and pancreas is heterogenous with variable clinical features and disease outcomes. Despite multiple attempts of risk stratification by grading and staging, some have unpredictable clinical courses. Well-differentiated grade 3 neuroendocrine tumour (G3NET) is a recent subcategory introduced in the 2019 WHO classification based on morphology, molecular profile and prognosis distinguishing it from neuroendocrine carcinoma(NEC).

An outcome-based composite approach for the diagnosis of intestinal tuberculosis: a pilot study from a tertiary care centre in South India.

Background: The diagnosis of intestinal TB (ITB) is challenging because of its overlapping features with Crohn's disease. This outcome-based study evaluated the combination of colonoscopy, histopathology, Xpert MTB/RIF and TB culture for best sensitivity and specificity.

Method: This was a four-year retrospective, observational study of 426 clinically suspected patients who underwent colonoscopy with biopsies for histopathology, Xpert MTB/RIF and TB culture.

Pilot Nanostring PanCancer pathway analysis of colon adenocarcinoma in a tertiary healthcare centre in Kerala, India.

The prevalence of microsatellite instability and deoxyribonucleic acid mismatch repair deficiency in colorectal adenocarcinoma (CRC) cases is higher in India compared to western populations. No major study on the molecular pathogenesis is currently available in the Indian population. We conducted a pilot study to explore the differences in molecular pathogenesis of microsatellite stable (MSS) and microsatellite unstable CRC from a tertiary care centre in Kerala, South India.

Best practices of handling, processing, and interpretation of small intestinal biopsies for the diagnosis and management of celiac disease: A joint consensus of Indian association of pathologists and microbiologists and Indian society of gastroenterology.

The Indian Association of Pathologists and Microbiologists (IAPM) and Indian Society of Gastroenterology (ISG) decided to make a joint consensus recommendation for handling, processing, and interpretation of SI biopsies for the diagnosis and management of celiac disease (CD) recognizing the inhomogeneous practice of biopsy sampling, orientation, processing, and interpretation. A modified Delphi process was used to develop this consensus document containing a total of 42 statements and recommendations, which were generated by sharing the document draft, incorporating expert's opinion, followed by three cycles of electronic voting as well as a full-day face-to-face virtual ZOOM meeting and review of supporting literature. Of the 42 statements, 7 statements are on small intestinal (SI) biopsy in suspected patients of CD, site and the number of biopsies; 7 on handling, fixative, orientation, processing, and sectioning in pathology laboratories; 2 on histological orientation; 13 statements on histological interpretation and histological grading; 3 on the assessment of follow-up biopsies; 2 statements on gluten-free diet (GFD)-nonresponsive CD; 4 on challenges in the diagnosis of CD; 2 statements each on pathology reporting protocol and training and infrastructure in this area.

SPS(Kayexalate)/CPS(K-Bind) crystals in the gastrointestinal tract-An experience from a tertiary center.

Introduction: Kayexalate (Sodium Polystyrene Sulfonate/SPS) and K-bind (Calcium Polystyrene Sulfonate/CPS) are cation exchange resins, commonly used for treatment of hyperkalaemia. SPS/CPS induced injury of the gastrointestinal tract(GIT) is rare, can be potentially life threatening but is under-recognized. This study aims to increase awareness of pathologists and clinicians of this under-reported complication of a drug commonly used to treat hyperkalaemia.

Grossing and reporting of colorectal cancer resection specimens: An evidence-based approach.

Appropriate management of the patient with colorectal carcinoma depends on obtaining key prognostic and predictive information from the resection specimen. These include the quality of surgery, extent of lymph nodal clearance, presence of nodal disease, vascular invasion, residual disease post neoadjuvant treatment, and completeness of resection. A meticulous and structured approach to dissection of the resection specimen and subsequent histological examination by the pathologist is crucial in providing this information to the treating clinician.

Prognostic and predictive significance of microsatellite instability in stage II colorectal carcinoma: An 8-year study from a tertiary center in South India.

Background: Microsatellite instability (MSI) accounts for 15-20% of colorectal cancer (CRC) and is considered to have favorable stage-adjusted prognosis compared to Microsatellite stable (MSS) CRCs. Determination of MSI in stage II CRC is important for management decisions regarding adjuvant chemotherapy administration. The aim of this study was to determine the prognostic and predictive significance of MSI in stage 2 CRC in the Indian scenario.

Congenital Cystic Adenomatoid Malformation: A Tertiary Care Hospital Experience.

Introduction: Congenital Cystic Adenomatoid Malformation (CCAM) is an uncommon developmental deformity affecting the terminal respiratory structures. It is characterized by broncho pulmonary foregut malformations. The reason behind it is an arrest in lung development between 4 and 7 week of fetal life.

Colonic polyposis syndromes--an experience from a tertiary centre in South India.

Background: Several polyposis syndromes of the gastrointestinal tract have been recognized which carry increased risk for cancer and have a genetic predisposition. There is a paucity of literature regarding the occurrence and the burden of colonic polyposis syndromes in the Indian subcontinent. This study attempts to highlight this hitherto unaddressed burden and the associated increased risk for inherited colonic cancer in this geographical location.
