Background: Carcinoma cervix contributes to a major proportion of cancer treatment in tertiary oncology centers. The outcomes are dependent on multiple factors. We conducted an audit to establish the pattern of treatment practiced for carcinoma cervix at the institute and suggest changes thereof to improve the quality of care.

Purpose: To evaluate feasibility and safety of execution of optimized intra-cavitary brachytherapy (ICBT) plan of first fraction in subsequent fractions in high-volume, low-resource centers.

Material And Methods: This non-randomized prospective study included 30 cervical cancer patients, who underwent 4 fractions of high-dose-rate (HDR)-ICBT in 2 applications, one week apart, 2 fractions per application delivered on two consecutive days. Computed tomography (CT) simulation was done before each fraction, organs at risk (OARs) were contoured on all sets of CT images.

Purpose: Interstitial brachytherapy (ISBT) is often used as post-external beam radiotherapy (EBRT) to treat locally advanced gynecological malignancies. Female urethra is in close proximity to the target during ISBT. However, it has not been evaluated as an organ-at-risk (OAR).

Background: While brain metastases (BM) are the most common causes of neurologic disorders in patients with known systemic malignancies, they can often be the initial manifestations of an undetected primary elsewhere. BM are major causes of morbidity and mortality in cancer patients.

Aims: We describe a mixed population (data from both retrospective and prospective collection) having a BM from a solid tumor.

Pineoblastomas are rare, malignant, pineal region lesions that account for <0.1% of all intracranial tumors and can metastasize along the neuroaxis. Pineoblastomas are more common in children than in adults and adults account for <10% of patients.

Article Synopsis
  • Over the last two decades, cancer research in India has significantly expanded, involving collaboration among clinicians, scientists, and policymakers to improve health outcomes through both low-tech and advanced research initiatives.
  • The paper emphasizes the need for enhanced research capacity, training for clinical researchers, and better support and funding from the government to strengthen the cancer research framework in India.
  • It highlights the importance of developing national infrastructures like clinical trials and tissue banking, while advocating for improved translation of research into tangible public health benefits.

Cancer can have profound social and economic consequences for people in India, often leading to family impoverishment and societal inequity. Reported age-adjusted incidence rates for cancer are still quite low in the demographically young country. Slightly more than 1 million new cases of cancer are diagnosed every year in a population of 1.

Radiotherapy has a significant impact on the local tumor environment and its distant component. Abscopal effect is the bystander effect of radiotherapy observed at a site distant to that irradiated within the same subject. Abscopal effect even though described, is not a common clinical event.

In the current study we tested if highest incidence of benign as well as cancer growths in breast tissue is due to constitutive molecular composition of this tissue. To delineate the molecular basis, we compared the expression of nine functional gene modules (total 578 genes) that regulate major positive growth and negative inhibitory signals in normal breast with two other reproductive tissues, ovary and uterus. We present data to demonstrate that breast tissues constitutively have very highly elevated levels of several growth promoting molecules and diminished levels of inhibitory molecules which may, in part, contribute for highest incidence of tumor growths in this tissue.

Subcutaneous sarcoidosis (also known as 'Darier-Roussy sarcoid') is a cutaneous condition characterized by numerous deep-seated nodules on the trunk and extremities. Coexistence of sarcoidosis and breast cancer are reported in the literature, but there will always be a chance of misdiagnosis. It is very crucial to obtain a tissue diagnosis of suspicious metastatic lesions.
