Introduction: Central Nervous System (CNS) tumours are a common cause of cancer-related deaths in adolescents and young adults. The challenges in diagnosing and treating CNS tumours in this age group are unique and require special attention. Aim: To study the histopathological spectrum of CNS tumours in Adolescents and Young Adults (AYA). Materials and Methods: Present five-year cross-sectional study was conducted on CNS biopsies received in the Department of Pathology at Dayanand Medical College and Hospital, Ludhiana, Punjab, India, from July 1, 2016, to June 30, 2021, to analyse the histopathological spectrum of CNS tumours in the AYA group based on the site of the lesion, age, gender, and Isocitrate Dehydrogenase (IDH) status. Results: During the study period, a total of 215 cases of CNS tumours were identified, of which 52 (24.2%) belonged to the AYA group. Of these, 35 (67.3%) were males and 17 (32.7%) were females. The majority of the patients presented with complaints of headache (50/52, 96.1%), with the frontal lobe being the most common site of involvement (21/52, 40.4%). Diffuse astrocytic and oligodendroglial tumours were the most commonly observed (23/52, 44.2%). Conclusion: CNS tumours are one of the most common cancer diagnosis among the AYA group, and awareness should be enhanced among histopathologists and oncologists regarding these tumours based on the updated classification.

Background and Objective: An accurate Ki-67 labeling index assessment is critical for managing a few tumors, like breast carcinomas and neuroendocrine tumors. We aimed to determine the degree of agreement between digital image analysis (DIA) and eye-rolling assessment (EE) and DIA and manual count (MC) for Ki-67 LI scoring. Methods: A total of 120 cases (both tru-cut biopsies and resected specimens) were selected during the study period from the institutional database, wherein the Ki-67 labeling index was performed. The selected cases were divided into two groups, i.e., breast neoplasms and other neoplasms. The correlation between DIA and EE and DIA and MC for Ki-67 LI scoring was calculated in both groups. Results: A total of 113 cases were analyzed for Ki-67 LI by three different methods (EE, MC, and DIA); 7 cases were rejected due to poor image quality. Ki-67 LI scoring by DIA and EE was highly correlated in both study groups with a Spearman's rank correlation coefficient of 0.809 (P=0.01) and 0.904 (P=0.01), respectively. Correlation between DIA and MC methods was also found to be almost perfect in both study groups with a Spearman's rank correlation coefficient of 0.974 (P=0.01) and 0.955 (P=0.01), respectively. Conclusion: ImmunoRatio is a free web-based digital image analysis application that can be used for Ki-67 LI assessment with considerable reliability and reproducibility. Yet, it carries a few limitations and demands a careful approach and final confirmation by an expert. [ABSTRACT FROM AUTHOR]

Background. Autologous stem cell transplantation (ASCT) is potentially beneficial for patients with myelomarelated renal impairment but is associated with high rates of complications in dialysis-dependent patients and requires specific precautions. Methods. Patients diagnosed with myeloma and concomitant dialysis-dependent renal dysfunction were admitted for ASCT after achieving at least partial response with bortezomib-based induction therapy. For both patients, mobilization consisted of granulocyte colony stimulating factor for 5 days and CD34 directed Plerixafor on Day 1. Melphalan was administered at a dose of 140 mg/m2 and a pre-emptive session of haemodialysis was planned 24 hours after melphalan. Peripheral blood stem cell infusion was done after 24 hours. A central venous sample for blood gas analysis was obtained daily and ad hoc dialysis was planned at the earliest sign of metabolic acidosis (pH <7.35, HCO3 <15 or K >6 mEq/L). Results. Two patients with biopsy proven cast nephropathy and dialysis dependence (twice a week) were taken for ASCT with the above protocol. No variation from usual stem cell yield or engraftment kinetics was noted. Patient 1 (M, 49 years) achieved very good partial response posttransplant and has been dialysis free for 18 months post-ASCT. Patient 2 (M, 48 years) achieved negative immunofixation post-ASCT and was dialysis free for 9 months post-transplant, following which he requires one session of dialysis every 3-4 weeks for onset of uraemic symptoms. Conclusions. ASCT in dialysis-dependent patients is associated with a higher risk of drug toxicity, infections and transplant-related mortality. Use of reduced dose melphalan, pre-emptive dialysis after 24 hours and monitoring for acidosis and symptoms of uraemia to identify acidosis at an early stage allows safe administration of high dose chemotherapy. A major proportion of patients can potentially achieve reduction or freedom from dialysis support posttransplant. [ABSTRACT FROM AUTHOR]

Background/Aims: Primary sclerosing cholangitis (PSC) represents the most common hepatobiliary extraintestinal manifestation of inflammatory bowel disease (IBD), including ulcerative colitis (UC) and Crohn's disease (CD). Limited data exist on PSC in patients with IBD from India. We aimed to assess the prevalence and disease spectrum of PSC in Indian patients with IBD. Methods: Database of IBD patients at 5 tertiary care IBD centers in India were analyzed retrospectively. Data were extracted and the prevalence of PSC-IBD was calculated. Results: Forty-eight patients out of 12,216 patients with IBD (9,231 UC, 2,939 CD, and 46 IBD unclassified) were identified to have PSC, resulting in a prevalence of 0.39%. The UC to CD ratio was 7:1. Male sex and pancolitis (UC) or colonic CD were more commonly associated with PSC-IBD. The diagnosis of IBD preceded the diagnosis of PSC in most of the patients. Majority of the patients were symptomatic for liver disease at diagnosis. Eight patients (16.66%) developed cirrhosis, 5 patients (10.41%), all UC, developed malignancies (3 colorectal cancer [6.25%] and 2 cholangiocarcinoma [4.16%]), and 3 patients died (2 decompensated liver disease [4.16%] and 1 cholangiocarcinoma [2.08%]) on follow-up. None of the patients mandated surgical therapy for IBD. Conclusions: Concomitant PSC in patients with IBD is uncommon in India and is associated with lower rates of development of malignancies.

Background/Aims: Inflammatory bowel disease (IBD) is increasingly being recognized in elderly patients. Data on clinical spectrum of elderly-onset IBD patients is lacking from India. Methods: A cross-sectional retrospective analysis of a prospectively maintained database of patients diagnosed with IBD was conducted at 2 centers in India. The clinical spectrum of elderly-onset IBD including demographic profile (age and sex), clinical presentation, disease characteristics (disease behavior and severity, extent of disease), and treatment were recorded and compared with adult-onset IBD. Results: During the study period, 3,922 (3,172 ulcerative colitis [UC] and 750 Crohn's disease [CD]) patients with IBD were recorded in the database. A total of 186 patients (4.74%; 116 males [62.36%]) had elderly-onset IBD (69.35% UC and 30.64% CD). Diarrhea, blood in stools, nocturnal frequency and pain abdomen were the commonest presentations for UC, whereas pain abdomen, weight loss and diarrhea were the most frequent symptoms in CD. For both elderly onset UC and CD, majority of the patients had moderately severe disease. Left-sided colitis was the commonest disease location in UC. Isolated ileal disease and inflammatory behavior were the most common disease location and behavior, respectively in CD. 5-Aminosalicylates were the commonest prescribed drug for both elderly onset UC and CD. Thiopurines and biologics were used infrequently. Prevalence of colorectal cancer was higher in elderly onset IBD. Conclusions: Elderly onset IBD is not uncommon in India. Both the elderly onset UC and CD were milder, with no significant differences in disease characteristics (disease extent, location and behavior) when compared to adult-onset IBD. Colorectal cancer was more common in elderly onset IBD. [ABSTRACT FROM AUTHOR]

Background: Magnetic resonance imaging (MRI) has been shown to be an accurate imaging technique for the preoperative assessment of local staging of endometrial cancer and for evaluating the depth of myometrial invasion. Materials and Methods: This was a single-center retrospective study performed on patients with histopathologically proven endometrial carcinoma who underwent an MRI examination of the pelvis between October 2017 and May 2020. Results: In the present analysis, mean apparent diffusion coefficient (ADC) values for each histologic grade were 0.72 ± 0.13 × 10−3 mm2/s (G1), 0.76 ± 0.17 × 10−3 mm2/s (G2), and 0.74 ± 0.12 × 10−3 mm2/s (G3), respectively, showing no significant correlation between ADC values and tumor grade (P = 0.73). Overall, ADC minimum was significant in differentiating grades of endometrial carcinoma (P = 0.02) with the ability to differentiate Grade I and II lesions (P = 0.01). A mean tumor volume of 25.2 cc could differentiate low-grade tumors (Grade I and Grade II) from high-grade tumors (Grade III) with a sensitivity and specificity of 88% and specificity of 89%. The tumor volume/uterine volume ratio (TV/UV) differentiates high-grade tumors from low-grade tumors (P < 0.001), however, no significant difference in the ratio was observed among Grade I and II lesions (P = 0.48). The area under the curve of tumor volume was 0.875 (95% confidence interval 0.0–1.00) (P = 0.001), indicating that tumor volume was an effective tool for distinguishing high-grade and low-grade endometrioid adenocarcinomas. The corresponding sensitivity and specificity were 88.0% and 89.0%, respectively. Conclusion: Preoperative noninvasive radiological assessment for tumor volume, TV/ UV or tumor volume/uterine volume is important surrogate markers for preoperative prognostication of endometrial carcinoma.
