The contemporary literature documents limited treatment approaches for patients with NSCLC relapse or nonresponsiveness to second-/third-generation ALK-TKIs. We hereby provide a descriptive analysis of five NSCLC cases treated with crizotinib, ceritinib, and alectinib for a median duration of 54 months. The outcomes indicate a profound therapeutic response in patients receiving 4th and subsequent line of treatment with crizotinib. The crizotinib retreatment actively reduced patient resistance to the ALK-TKIs by reversing the mesenchymal epithelial transition amplification. The results from this case series also emphasize the possible role of next-generation sequencing in determining therapeutic resistance and transforming the treatment paradigm for NSCLC. Partial response was observed in the patients after 6 months of crizotinib readministration. This is possibly the first case series reporting crizotinib rechallenge in patients of ALK positive NSCLC who failed on subsequent ALK-TKIs and multiple lines of chemotherapies.","PeriodicalId":13513,"journal":{"name":"Indian Journal of Medical and Paediatric Oncology","volume":"25 12","pages":""},"PeriodicalIF":0.2,"publicationDate":"2023-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139151696","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is largely different from follicular lymphoma (FL). Few published studies on PFL are case series in developed nations. We report on a patient with advanced PFL, a 14-year-old female with 5-year history of neck swellings, abdominal distension for a month, and pericardial effusion, among others. The swellings waxed and waned; and involved all the peripheral lymph nodes. Tuberculosis (TB) GeneXpert and human immunodeficiency virus (HIV) screening were negative. She received anti-TB drugs prior to presentation in our hospital where nodal histopathology showed effaced architecture with diffuse follicles and abundant blastoid cells as well as negative CD5 and BCL2, and positive CD10 and CD20. Diagnosis of PFL (stage 3) was made. She completed six courses of cyclophosphamide, doxorubicin, vincristine, and prednisolone and is well 9 months after therapy. The PFL usually presents with stage 1 or 2 disease unlike in the index female case that was also complicated by effusion and ascites due to late presentation. It responded to chemotherapy and has not reoccurred; in contrast to classic FL and reactive follicular hyperplasia (RFH) which should be differentiated from PFL. Although RFH can be caused by TB or HIV, they are not causes of malignant lymphadenopathy. Physicians should be aware of PFL which may present in high clinical stages, but still retain its good prognosis, for the purposes of counseling.","PeriodicalId":13513,"journal":{"name":"Indian Journal of Medical and Paediatric Oncology","volume":" 35","pages":""},"PeriodicalIF":0.2,"publicationDate":"2023-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138961099","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Following induction treatment, cytogenetic examination can establish the presence of any residual malignant cells, it's recurrence, clonal evolution if any, or the formation of novel abnormalities. The G-banded karyotype has been the gold standard method for detecting all of these aberrations for years. The capacity to examine the entire genome through karyotype analysis quickly enabled the detection of deletions, duplications, and structural rearrangements across every chromosome, and the more frequent ones were associated with particular aberrant clinical symptoms. Fluorescence in situ hybridization (FISH) is a sensitive technology that aids in differential diagnosis or therapeutic planning and provides rapid results. Furthermore, the combination of cytogenetic and molecular profiling enables a more precise evaluation of disease prognosis, diagnosis, classification, risk stratification, and patient treatment. Interphase FISH analysis, in conjunction with G-banded chromosomal analysis, can be used as a major testing tool for the evaluation of hematological neoplasms. For accurate and consistent descriptions of genomic changes identified by karyotyping and FISH, a specified terminology is necessary. The International System for Human Cytogenomic Nomenclature is the main source and provides instructions for documenting cytogenetic and molecular findings in laboratory reports. This review discusses the two methods, karyotyping and FISH, their advantages and limitations, sample requirements, various FISH probes that are used, nomenclature for results reporting, and the necessary quality control measures.","PeriodicalId":13513,"journal":{"name":"Indian Journal of Medical and Paediatric Oncology","volume":"1 1","pages":"543 - 553"},"PeriodicalIF":0.2,"publicationDate":"2023-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139229944","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The use of tyrosine kinase inhibitor (TKI) against the chimeric BCR::ABL1 fusion protein has led to a paradigm shift in CML patient outcomes. Despite generational advancements in TKI, a fraction of patients harbor residual disease or exhibit resistance to TKI. The importance of disease monitoring and detection of resistance mechanisms has gained prominence with increasing knowledge about disease evolution. In the past, cytogenetic techniques such as karyotyping and fluorescence in situ hybridization were widely utilized for monitoring disease and prognostication. These techniques had various challenges related to limited sensitivity in minimal residual disease (MRD) monitoring; however, their importance still holds in the detection of additional chromosomal aberrations and in cases with cryptic insertions, variants, and masked Philadelphia chromosome. Molecular genetics has evolved significantly from the past to the present times for MRD monitoring in CML patients. Qualitative reverse transcription polymerase chain reaction (RQ-PCR) can be performed at diagnosis to detect the BCR::ABL1 transcript, while quantitative RQ-PCR is the most widely used and well-standardized MRD monitoring method. The DNA-based assays demonstrated high sensitivity and specificity, with many efforts directed toward making the laborious step of BCR::ABL1 breakpoint characterization less tedious to increase the utility of DNA-based MRD approach in the future. Flow cytometric–based approaches for the detection of the BCR::ABL1 fusion protein have been under trial with a scope of becoming a more robust and convenient methodology for monitoring in the future. Upcoming techniques such as digital PCR and ultra-deep sequencing next-generation sequencing (UDS-NGS) have shown promising results in residual disease monitoring and detection of resistance mutations. Novel MRD monitoring systems that are independent of BCR::ABL1 fusion such as the detection of CD26+ leukemic stem cells and microRNA mutations are the future of residual disease monitoring, which can go up to the level of a single cell. In this review, we tried to discuss the evolution of most of the above-mentioned techniques encompassing the pros, cons, utility, and challenges for MRD monitoring and detection of TKI resistance mutations.","PeriodicalId":13513,"journal":{"name":"Indian Journal of Medical and Paediatric Oncology","volume":"7 1","pages":"592 - 601"},"PeriodicalIF":0.2,"publicationDate":"2023-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139232635","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
