The field of genetic counseling in India has enormously transformed over the past few years. Genetic counseling is a communication process which deals with the human problems associated with the occurrence or risk of occurrence of a genetic disorder in a family. Genetic counseling is not merely having a conversation based on genomic data. It addresses the "information needs" of a particular patient, and customizes a session according to each patient's individual circumstances, thereby aiding in decision-making. ABL001 In 2012, AIIMS (New Delhi) became the first tertiary care center in North India to provide genetic counseling for cancer. Among 200 cases that were referred for genetic counseling to the AIIMS clinic at the Department of Surgical Disciplines, about 30% of patients chose to undergo testing. Five cases of BRCA1/2 mutation were found conforming to the hereditary breast and ovarian cancer syndrome. There was one case of TP53 mutation conforming to Li-Fraumeni syndrome. One case each of Xeroderma Pigmentosum (XP) and Cowden's syndrome was also detected. All these cases were offered risk-reducing measures and put under life-long surveillance as per protocol. Their family members were also offered genetic counseling and subsequent testing if they agreed. Cancer genetic counseling service was a new exercise, and hence, several challenges were faced. The clinical utility of genetic testing, coupled with counseling, should be established by trials. Documenting the achievements of counseling by surrogate parameters like "improved recruitment rate of patients for genetic tests" and "improved patient satisfaction levels" will go a long way in garnering the much needed institutional support.CanAssist Breast (CAB) has thus far been validated on a retrospective cohort of 1123 patients who are mostly Indians. Distant metastasis-free survival (DMFS) of more than 95% was observed with significant separation (P  less then  0.0001) between low-risk and high-risk groups. In this study, we demonstrate the usefulness of CAB in guiding physicians to assess risk of cancer recurrence and to make informed treatment decisions for patients. Of more than 500 patients who have undergone CAB test, detailed analysis of 455 patients who were treated based on CAB-based risk predictions by more than 140 doctors across India is presented here. Majority of patients tested had node negative, T2, and grade 2 disease. Age and luminal subtypes did not affect the performance of CAB. On comparison with Adjuvant! Online (AOL), CAB categorized twice the number of patients into low risk indicating potential of overtreatment by AOL-based risk categorization. We assessed the impact of CAB testing on treatment decisions for 254 patients and observed that 92% low-risk patients were not given chemotherapy. Overall, we observed that 88% patients were either given or not given chemotherapy based on whether they were stratified as high risk or low risk for distant recurrence respectively. Based on these results, we conclude that CAB has been accepted by physicians to make treatment planning and provides a cost-effective alternative to other similar multigene prognostic tests currently available.Breast cancer is no longer considered a single disease, and with better understanding of cancer biology, its management has evolved over the years, into a complex individualized use of therapeutics based on variable expressions of predictive and prognostic factors. With the advent of molecular and genetic research, the complexity and diversity of breast cancer cells and their ability to survive and develop resistance to treatment strategies became more evident. At the same time, targeted therapies evolved, as specific targets were discovered such as HER2 receptor, and androgen receptor. More recent is the development of immunotherapy which aims at strengthening the host immune system to identify and kill the tumor cells. In breast cancer treatment, use of molecular tests has been a target of controversies, due to their high costs and inaccessibility in limited resource situations. Research in breast cancer is also proceeding at a rapid pace, but it is important to remember that breast cancer continues to be a complex interplay of alterations at molecular and genetic level, with the variability in expressions at protein level leading to difference in behavior and responses to treatment and overall outcome. In the succeeding paragraphs, we will try to review the available evidence in literature and attempt to understand the molecular complexity of breast cancer in order to simplify the art of treating the disease and improving outcomes.The current COVID-19 pandemic has led to severe disruptions in health care delivery for cancer patients. These interruptions in cancer care delivery may have an unknown effect on cancer outcomes at the individual and population level. These yet to be known variations in individual and population-level cancer outcomes resulting from COVID-19 related interruptions in care can be labeled as COVID-19 Stage Migration (CSM).Hepatitis E is one of the leading causes of acute viral hepatitis worldwide. Chronic infection with hepatitis E is less common and limited to immunosuppressed patients and is usually due to genotype 3 of the virus. Genotype 1, the most prevalent strain in the South Asian region, is seldom known to be associated with chronic hepatitis. Here we describe a case of chronic hepatitis E with genotype 1 in a post-liver transplant setting. In the index case, previously compensated cryptogenic cirrhosis was decompensated by an acute hepatitis E infection, which necessitated liver transplantation because of acute chronic liver failure. This later progressed to chronicity. This case may have significant implications in management, especially in the post-liver transplant setting.Hepatic encephalopathy due to portosystemic shunts is a well-defined entity in patients with cirrhosis. Rarely, liver transplant recipients develop hepatic encephalopathy owing to persistence or surgically created portosystemic shunts. We present a case of post-transplant recurrent hepatic encephalopathy due to a surgically created portocaval shunt. The patient was managed by a covered metal stent placement in the inferior vena cava, thus causing functional closure of the shunt.
