Purpose: For cervical cancer patients, intra-cavitary brachytherapy (ICBT) is utilized with various dose-rate systems, such as low-dose-rate (LDR), high-dose-rate (HDR), and pulsed-dose-rate (PDR). This retrospective analysis aimed to compare the therapeutic outcomes of cervical cancer patients treated with either LDR-, HDR-, or PDR-ICBT.

Material And Methods: A total of 613 patients were treated with pelvic external beam radiation therapy (EBRT), followed by either LDR- (271 patients), HDR- (259 patients), or PDR- (83 patients) ICBT.

Article Synopsis
  • The study examines the effectiveness of volumetric modulated arc therapy (VMAT) in delivering low-dose radiation therapy (LDRT) to the lungs of COVID-19 patients while minimizing the risk of long-term radiation-induced cancer (RIC).
  • By analyzing data from 10 patients previously treated for thoracic malignancies, the researchers compared the dosimetry of VMAT with a conventional radiation technique, finding that VMAT significantly lowered doses to organs at risk (OARs) and the bone marrow.
  • The results showed that VMAT not only improved dosimetry parameters but also reduced the estimated lifetime attributable risk of cancer, making it the preferred method for lung LDRT in COVID-19 patients requiring doses of 1

Introduction: Surface mold brachytherapy (SMBT) is an established treatment modality in skin cancer, especially in accessible areas, and has shown comparable outcomes to surgery. We have presented our results for the skin tumor treatment with SMBT treated with high-dose-rate (HDR) brachytherapy in terms of clinical outcomes and toxicity at our institute.

Materials And Methods: In this retrospective analysis, 15 patients with skin cancer were treated with customized tube-based SMBT at our institute between January 2019 and July 2021.

  • - The study focuses on synthesizing eco-friendly titanium dioxide (TiO) nanoparticles using hibiscus leaf extract, creating TiO-doped g-CN (TiCN) nanocomposites in varying concentrations through thermal polymerization.
  • - Multiple analytical techniques were employed to characterize the TiO nanoparticles and TiCN composites, revealing that the TiCN(1.5 mM) sample has a surface area of 112.287 m²/g, a pore size of 7.056 nm, and confirmed the inclusion of carbon and nitrogen elements.
  • - The TiCN(1.5 mM) composites demonstrated improved morphology, better light absorption, and effective photocatalytic activity for degrading rhodamine B and Bisphen

Introduction: A significant proportion of breast cancer cases are hereditary and are potentially preventable. However, adoption of the preventive measures remains a significant challenge, particularly because of to lack of knowledge and awareness in low- to middle-income countries.

Methods: This prospective study conducted at a high-volume tertiary care cancer center in North India to assess the knowledge, awareness, and attitudes of female breast cancer patients and impact of a brief educational intervention.

Objective: Hirayama disease is a rare cause of cervical myelopathy predominantly affecting young individuals. The disease is classically characterized by muscle atrophy in the distal upper limbs. While various etiopathogenesis such as dural sac dysplasia, nerve root dysplasia, structural abnormalities of the spinal ligament, and venous dysplasia have been proposed, this study explores the potential role of venous pathology and surgical management on the basis of it.

Introduction: Breast cancer is the most common cancer among Indian females. There is limited data on germline profiling of breast cancer patients from India.

Objective: The objective of the current study was to analyse the frequency and spectrum of germline variant profiles and clinicopathological characteristics of breast cancer patients referred to our Familial Cancer Clinic (FCC).

Article Synopsis
  • The study projects that by 2040, around 161,000 patients in India will be eligible for particle therapy, indicating a growing demand for therapy facilities from 81-97 in 2020 to 121-146 by 2040.
  • Economic analysis shows that while capital costs for particle therapy are higher than conventional treatments, the treatment price per patient fraction could be significantly lower than that in higher-income countries, making it more accessible.
  • Despite challenges like resource limitations and the need for trained professionals, the research concludes that large-scale proton therapy is the most viable option, with a phased implementation strategy suggested to effectively tackle these barriers.

Objective: Low back pain (LBP) is a major cause of pain and disability. Identification of the pathology accurately or the pain generators is sometimes difficult with the conventional modalities such as magnetic resonance imaging (MRI), computed tomography (CT), or X-ray. Nuclear medicine investigations such as single-photon emission CT (SPECT/CT) or 18-fluorodeoxyglucose positron emission tomography-CT (18-FDG PET-CT) have emerged as an adjuvant tool in these cases.

Purpose: Interstitial brachytherapy (ISBT) is indicated for intact cervical carcinoma (IN-CC) if intracavitary brachytherapy (ICRT) is not feasible and also in vault carcinoma (VA-C). We aimed to evaluate the doses to pelvic lymph node regions in IN-CC and VA-C treated with ISBT.

Material And Methods: Ten patients (6 IN-CC, 4 VA-C) were chosen for this dosimetric study.

Background: Neoadjuvant chemotherapy (NACT) with human epidermal growth factor receptor 2 (HER2) blockade is the preferred approach for treating early and locally advanced HER2-positive breast cancer. There is a lack of robust data comparing pathological complete response (pCR) and survival outcomes in anthracycline-free and anthracycline-containing regimens with single HER2-targeted therapy.

Objectives: The present study retrospectively evaluated pCR between two groups: Single HER2-targeted therapy with and without anthracycline.

Since the electroplating and alloy industries continuously pollute water resources, this paper presents a novel adsorbent to adsorb nickel ions from aqueous solutions prepared in the lab. Chhotidudhi, a creeping weed that is commonly called Euphorbia thymifolia, was used as an adsorbent in its pristine and activated forms. In order to characterize the structure, morphology, and thermal properties of ground Euphorbia thymifolia (ETR) and activated Euphorbia thymifolia (ETA), Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), scanning electron microscope (SEM), and thermal gravimetric analysis (TGA) were used.
