Objectives: Patients with advanced cancer with incurable diseases are generally cared for by their families in India. There is a lack of data on the perceived caregiver burden, quality of life (QOL) of patients and caregivers in India, especially among cancer patients not on any oncologic management.

Material And Methods: We conducted a cross-sectional study among 220 patients of advanced cancer on best supportive care and their respective 220 family caregivers.

Background: Triple-negative subtype is an aggressive breast cancer with inferior survival. Pathological complete remission (pCR) is a good surrogate endpoint for survival among patients receiving neoadjuvant chemotherapy (NACT). We attempted to validate the clinical pathological score (CPS) with a modified risk grouping among Triple-negative breast cancer (TNBC) patients receiving NACT at our center.

Lung cancer is one of the most common cancers and an important cause of cancer-related mortality. Recent advances in targeted therapy and immunotherapy have improved outcomes, but these have limited penetration in resource-constrained situations. We report the real-world experience in treating patients with lung cancer in India.

Background: Head and neck cancer constitute one-third of all cancers. Due to the complex nature of Head and Neck Cancer treatment, expenditure on cancer treatment are higher and the Quality of Life of patients is also compromised. The objectives of the study were to determine the time taken by patients for seeking care from registered medical practitioners, time to definitive diagnosis and treatment initiation, expenditure incurred, and Quality of Life.

Purpose: To dosimetrically compare high-dose-rate interstitial brachytherapy (HDR-BT) with volumetric-modulated arc therapy (VMAT) for tumor bed boost, following breast conservative treatment.

Material And Methods: 50 patients with early-stage breast cancer who underwent breast conservation surgery, followed by either HDR-BT ( = 25) of 15 Gy in 6 fractions over a period of 3 days, or VMAT dose of 16 Gy in 8 fractions ( = 25) for tumor bed boost, were retrospectively reviewed. All patients received whole breast irradiation of 46 Gy in 23 fractions.

Various DNA repair pathways protect the structural and chemical integrity of the human genome from environmental and endogenous threats. Polymorphisms of genes encoding the proteins involved in DNA repair have been found to be associated with cancer risk and chemotherapeutic response. In this study, we aim to establish the normative frequencies of DNA repair genes in South Indian healthy population and compare with HapMap populations.

DNA repair genes are crucial in maintaining the integrity of the whole genome. Single nucleotide polymorphisms (SNPs) in DNA repair genes have been attributed to the development of various cancers. SNPs of DNA repair genes (ERCC1 and ERCC2) have been implicated in the causation of various cancers as well as inter-individual variability in the therapeutic outcomes of platinum based therapy.

Hemophilic pseudotumor is an uncommon complication of factor VIII and IX deficiencies in the coagulation cascade and occurs in a wide spectrum of bones and soft tissues. We present a six-year-old boy with hemophilic pseudotumor localized in the right orbit. He showed a favorable response to radiation therapy after unsuccessful treatment with factor VIII replacement therapy with no recurrence till eight months.
