Lung cancer, particularly non-small-cell lung cancer (NSCLC), is a major global health issue. In India, the complexity of managing this disease is heightened by diverse demographics, varying healthcare access and evolving epidemiological trends influenced by factors such as smoking and advancements in diagnostics. This study explores cancer demographics and first-line palliative treatment options.

Background: Standard neoadjuvant chemotherapy for locally advanced esophageal or gastroesophageal junction squamous cancer, 5-fluorouracil plus platinum, is toxic and logistically challenging; alternative regimens are needed.

Methods: This was a phase III randomized open-label noninferiority trial at Tata Memorial Center, India, in resectable locally advanced esophageal or gastroesophageal junction squamous cancer. Patients were randomly assigned 1:1 to 3 cycles of 3-weekly platinum (cisplatin 75 mg/m2 or carboplatin area under the curve 6) with paclitaxel 175 mg/m2 (day 1) or 5-fluorouracil 1000 mg/m2 continuous infusion (days 1-4), followed by surgery.

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.

Background: Penile cancer is a rare malignancy with scant data on the impact of systemic therapy on outcomes.

Methods: Retrospective observational study of patients with a histological diagnosis of carcinoma penis treated with systemic therapy at the Tata Memorial Centre (Mumbai, India) between August 2010 and February 2018. Primary objective was overall survival (OS); secondary objectives included assessment of clinical characteristics, treatment approaches, and toxicity profiles.

Introduction: The outcomes in advanced NSCLC have improved owing to the availability of more effective systemic and improved supportive care. This has increased the number of patients who seek treatment in the third line and beyond setting. We conducted this study to compare the quality of life (QoL), toxicity, and outcomes in patients receiving chemotherapy and EGFR tyrosine kinase inhibitors (TKIs) in this setting.

Pantoprazole decreases the acidity of the tumor microenvironment by inhibiting proton pumps on the cancer cell. This possibly leads to increased sensitivity to cytotoxic therapy. We conducted a phase I/II randomized controlled trial in adult patients with head and neck squamous cell carcinoma (HNSCC) planned for first-line palliative chemotherapy.

Background: Anaplastic lymphoma kinase (ALK) inhibitors have shown significant efficacy in ALK -rearranged non-small cell lung cancer (NSCLC) patients with good performance status (PS) in multiple randomised studies. However, there is limited data on patients with poor performance status.

Patients And Methods: We carried out a retrospective analysis of prospectively collected data of patients with ALK-rearranged NSCLC and Eastern Cooperative Oncology Group (ECOG) PS of 2-4 treated at a single academic cancer centre from January 2013 to November 2018.

Introduction: Plasma cfDNA-based mutation analysis has shown disease-monitoring potential in various cancers. We assessed the potential of cfDNA-based EGFR mutation testing as a monitoring tool in patients with NSCLC.

Patients And Methods: Patients with NSCLC harboring EGFR mutations receiving first-line treatment as per institutional protocol were enrolled.

TFE Translocation renal cell carcinoma (TRCC) represents 1 to 5% of all cases of renal cell carcinoma, with the highest frequency among children and young adults. Management of these tumors is not very well defined in literature. Although in pediatric age group it has favorable prognosis, in adults it has an aggressive nature, with poor outcome.
