Background: ALK-positive lung cancers are known to have favorable responses with oral tyrosine kinase inhibitors. Lorlatinib is an approved treatment option post first and second-line ALK inhibitors and is now also in first line. We present a retrospective observational study of the safety and efficacy of patients receiving Lorlatinib in second-line and beyond.

Aim: To evaluate the prognostic impact of neutrophil-lymphocyte ratio (NLR), platelet-lymphocyte ratio (PLR) and lymphocyte-monocyte ratio (LMR) on overall survival (OS) among Indian older patients with cancer.

Methods: This observational study was conducted in the geriatric oncology clinic of Tata Memorial Hospital (India). We included all patients who underwent a geriatric assessment (GA) and had a complete blood count available for analysis.

Head and neck cancer management requires multidisciplinary approach in which radical surgery with or without flap reconstructions and neck dissection, along with radiotherapy (RT)/chemoradiotherapy (CRT) serve as the key components. Neoadjuvant chemotherapy and immunotherapy are used in selected cases based on the institutional preference. Knowledge of expected post-treatment changes on imaging is essential to differentiate it from recurrence.

Purpose: To report toxicity from the multicenter phase III randomized trial of Bladder Adjuvant Radiation Therapy (BART) after radical cystectomy and chemotherapy in high-risk muscle-invasive bladder cancer (MIBC).

Methods And Materials: Patients with nonmetastatic urothelial MIBC with ≥1 high-risk feature after radical cystectomy- pT3-4, pN1-3, nodal yield <10, positive margin, or ≥cT3 downstaged with neoadjuvant chemotherapy- were randomized 1:1 to observation (Obs) or adjuvant radiation therapy (RT) at 4 centers, stratified by pN stage (N0, N+) and chemotherapy (neoadjuvant, adjuvant, none). Stoma-sparing image guided intensity modulated RT 50.

Article Synopsis
  • - The study evaluates how well computed tomography (CT) can predict extrathyroidal extension (ETE) and tracheal invasion (TI) in patients with differentiated papillary thyroid carcinoma (PTC), comparing its accuracy to that of ultrasound (US).
  • - Data was collected from 83 patients who had both US and CT scans before surgery, focusing on the diagnostic performance based on sensitivity, specificity, and predictive values for detecting ETE and TI.
  • - Results indicate that while CT is fairly accurate and specific for ETE, its sensitivity is lower than that of US, implying that CT alone may not be sufficient for conclusive assessments in some cases.

Body temperature is a crucial indicator in assessing human physiological activity and health, particularly in pediatric and critically ill patients. This study aimed to compare temperature recordings obtained from digital calibrated thermometers with calibrated infrared thermometers and non-calibrated infrared thermometers against calibrated ones. An observational prospective study was conducted at AIIMS Bhopal, involving volunteers and febrile patients who consented to participate.

Purpose: Standard neoadjuvant chemotherapy (NACT) for locally advanced esophageal/gastroesophageal junction squamous cancer (LAEGSC), 5-fluorouracil (5FU)+platinum, is toxic and logistically challenging; alternative regimens are needed.

Patients And Methods: Phase III randomized open-label non-inferiority trial at Tata Memorial Center, India, in resectable LAEGSC. Patients were randomized 1:1 to three cycles of 3-weekly platinum (cisplatin 75 mg/m2 or carboplatin AUC 6) with paclitaxel 175 mg/m2 (day 1) or 5FU 1000 mg/m2 continuous infusion (days 1-4), followed by surgery.

Lung cancer varies between Caucasians and Asians. There have been differences recorded in the epidemiology, genomics, standard therapies and outcomes, with variations according to the geography and ethnicity which affect the decision for optimal treatment of the patients. To better understand the profile of lung cancer in Southeast Asia, with a focus on India, we have comprehensively reviewed the available data, and discuss the challenges and the way forward.

Background: The genomic landscape of non-small cell lung cancer (NSCLC) in the Indian patients remains underexplored. We revealed distinctive genomic alterations of Indian NSCLC patients, thereby providing vital molecular insights for implementation of precision therapies.

Methods: We analyzed the genomic profiles of 325 lung adenocarcinoma and 81 lung squamous carcinoma samples from Indian patients using targeted sequencing of 50 cancer related genes.

Purpose: Oral cancer is a significant global health concern, with high morbidity and mortality rates, particularly in regions with prevalent tobacco usage such as Asia. Majority of oral cancers are detected at an advanced stage resulting in poor survival outcomes. Moreover, the treatment modalities of oral cancers have remained constant with surgery and concurrent chemoradiotherapy being mainstays of the treatment.

Importance: The role of olanzapine has not been adequately evaluated in moderately emetogenic chemotherapy (MEC) regimens with or without neurokinin-1 receptor antagonists.

Objective: To evaluate whether addition of olanzapine to an MEC regimen reduces nausea, vomiting, and use of nausea rescue medications among patients with solid malignant tumors.

Design, Setting, And Participants: This multicenter, open-label phase 3 randomized clinical trial included patients aged 18 years or older with solid malignant tumors who were receiving oxaliplatin-, carboplatin-, or irinotecan-based chemotherapy.

Bladder cancer is a common malignancy worldwide, posing a substantial healthcare challenge. Current standard treatment regimens are primarily based on cisplatin, but their success is often limited by cisplatin resistance and associated toxicities. Therefore, there is an urgent need to develop effective and less toxic therapies as alternatives to cisplatin.

The global demographic and epidemiological transition have led to a rapidly increasing burden of cancer, particularly among older adults. There are scant data on the prevalence and demographic pattern of cancer in older Indian persons. This was a multicentric observational study conducted between January 2019 and December 2020.

Article Synopsis
  • No definitive studies previously showed that chemotherapy improved overall survival in advanced esophageal cancer, prompting a Phase III randomized trial comparing best supportive care (BSC) alone to BSC plus weekly paclitaxel.
  • The trial involved 281 patients, revealing that those on chemotherapy experienced a median overall survival of 9.2 months, compared to only 4.2 months for those on BSC.
  • Results showed that chemotherapy significantly improved response rates, progression-free survival, and quality of life, while not increasing severe toxicities, marking it as a valuable treatment option in this population.

Purpose: In the weekly-3-weekly study, cisplatin at 100 mg/m once-every-3-weeks led to superior locoregional control compared with cisplatin 30 mg/m once-a-week in combination with radical radiation for locally advanced head and neck squamous cell carcinoma (LAHNSCC). We report the updated analysis of the study.

Methods And Materials: In this phase 3 open-label noninferiority study conducted between 2013 and 2017, 300 patients with LAHNSCC were randomly assigned to receive cisplatin 100 mg/m once-in-every-weeks or cisplatin 30 mg/m once-a-week, concurrently with radiation.

Article Synopsis
  • The study aimed to assess if adding docetaxel (D) to standard chemotherapy regimens improved overall survival (OS) in patients with advanced HER2-negative gastroesophageal junction and gastric adenocarcinomas.
  • Out of 324 patients enrolled, the analysis showed that FOLFOX/CAPOX provided a median OS of 10.1 months, while the DOF/DOX regimen resulted in 8.9 months, with no significant survival advantage from the addition of docetaxel (P = .70).
  • The study also noted higher rates of severe neutropenia and neuropathy in the DOF/DOX group and identified a surprisingly high incidence of BRCA1 and BRCA2 alterations

Purpose: Nivolumab is approved at various doses, including 3 mg/kg, 240 mg and 480 mg flat doses at various dosing intervals. The concept of low-dose immunotherapy is gaining traction in recent years. However, there is a need to better understand the pharmacokinetics and clinical outcomes at lower doses.

Introduction: Osimertinib is more efficacious and as safe as first-generation epidermal growth factor receptor (EGFR)-directed tyrosine kinase inhibitors. However, osimertinib is not affordable for most patients in developing nations. Moreover, the minimum biologically effective dose of osimertinib may be less than the approved dose.
