Real-World Data on Treatment Outcome of ALK-Positive Non-Small Cell Lung Cancer from an Indian Multicentric Cancer Registry.

Lalatendu Moharana The Anaplastic lymphoma kinase inhibitors (ALKi) represent the standard of care for metastatic non-small cell lung cancer (NSCLC) patients with EML4-ALK rearrangements. Various ALKi agents are available; however, not all eligible patients receive treatment with them due to various reasons. Given the limited real-world data available in our country, we aimed to assess treatment outcomes through a multicenter collaboration.

Practical Consensus Guidelines for the Use of S-1 in GI Malignancies.

Purvish M ParikhS-1 (5-fluorouracil prodrug [tegafur] in combination with 5-chloro-2,4-dihydroxypyridine [CDHP] and potassium oxonate [OXO]) was first approved in 1999.

Correction: Rucaparib as a Salvage Treatment in Platinum-Sensitive Relapsed Ovarian Carcinoma: A Case Report.

[This corrects the article DOI: 10.7759/cureus.30405.

EVI1 upregulates PTGS1 (COX1) and decreases the action of tyrosine kinase inhibitors (TKIs) in chronic myeloid leukemia cells.

Tyrosine kinase inhibitors (TKIs) are highly effective in treating chronic myelogenous leukemia (CML). However, primary and acquired drug resistance to TKIs have been reported. In this study, we used RNA sequencing followed by RQ-PCR to show that the proto-oncogene EVI1 targets the drug-metabolizing gene PTGS1 in CML.

Rucaparib as a Salvage Treatment in Platinum-Sensitive Relapsed Ovarian Carcinoma: A Case Report.

One of the leading causes of female mortality worldwide is ovarian carcinoma. It can be divided into five main types: high-grade serous, endometrioid, clear cell, mucinous and low-grade serous carcinomas. These tumors represent distinct diseases and prognoses.

CONCORDANCE: A real-world evidence study to evaluate the concordance of detecting epidermal growth factor receptor (EGFR) mutation by circulating tumor DNA* versus tissue biopsy in patients with metastatic non-small cell lung cancer.

Background: Molecular tissue testing in non-small cell lung cancer (NSCLC) is done for the assessment of epidermal growth factor receptor (EGFR) mutation. EGFR mutation status is the basis for deciding the targeted treatment option for patients with metastatic NSCLC. The nonavailability of tissue samples and contraindications for biopsy pose a significant challenge.

Sequencing of Systemic Therapies in the Management of Advanced Prostate Cancer in India: a Delphi-Based Consensus.

Introduction: With the availability of an increasing number of therapeutic options for advanced prostate cancer (APC), optimal sequencing and combination of therapies have emerged to be the areas of challenges. In the Indian context, there is a dearth of consensus recommendations to guide clinicians regarding optimal sequencing of therapy in APC management. A Delphi-based consensus regarding optimal therapy sequencing in APC management was developed by an expert panel of medical oncologists from across India.

Management of Lymphomas: Consensus Document 2018 by an Indian Expert Group.

The clinical course of lymphoma depends on the indolent or aggressive nature of the disease. Hence, the optimal management of lymphoma needs a correct diagnosis and classification as B cell, T-cell or natural killer (NK)/T-cell as well as indolent or high-grade type lymphoma. The current consensus statement, developed by experts in the field across India, is intended to help healthcare professionals manage lymphomas in adults over 18 years of age.

Ecotropic viral integration site I regulates alpha1, 6-fucosyl transferase expression and blocks erythropoiesis in chronic myeloid leukemia.

Although BCR-ABL is the hallmark genetic abnormality of chronic myeloid leukemia (CML), secondary molecular events responsible for the evolution of the disease to blast crisis are yet to be deciphered. Taking into account the significant association of ecotropic viral integration site I (EVI1) in CML drug resistance, it is necessary to decipher the other roles played by EVI1 in CML disease progression. In this regard, we cross-hybridized three microarray datasets and deduced a set of 11 genes that seems to be regulated by EVI1 in CML.
