Practice of Tumor Bed Boost in Patients after Oncoplastic Breast-Conserving Surgery.

The practice of boost to the tumor bed after treatment with oncoplastic breast-conserving surgery (BCS) remains variable. Using a survey, the present study evaluated the current practice of tumor bed boost administered in women after oncoplastic BCS. Actively practicing radiation oncologists across India were sent a questionnaire on the practice of adjuvant whole-breast radiotherapy and tumor bed boost after oncoplastic BCS via email and encouraged to participate.

Radiotherapy management of rectal cancer in the backdrop of the COVID pandemic.

Background: COVID-19 outbreak was declared as a pandemic by the World Health Organization in March 2020. Over the last 3 months, the pandemic has challenged the diagnosis and treatment of all cancer, including rectal cancer. Constraints in resources call for a change in the treatment strategy without compromising efficacy.

An advisory by the association of radiation oncologists of India for radiation therapy patients and staff among COVID 19 pandemic.

Covid19 has become a major public health problem in India and the rest of the world. The dramatic rise in the incidence of COVID 19 cases has severely challenged our healthcare system and forced us to work with limited infrastructure, resources, and workforce. However, even in this time of adversity, we as oncologists cannot neglect the seriousness of cancer care and the utmost attention it requires for the timely management of our patients.

Stereotactic body radiotherapy for lung tumors: Dosimetric analysis and clinical outcome.

Introduction: Stereotactic body radiotherapy (SBRT) has emerged as an important modality in malignant lung tumor treatment both in early localized primary and oligometastatic setting. This study aims to present the results of lung SBRT both in terms of dosimetry and clinical outcome.

Materials And Methods: Twenty-seven patients were assessed from 2012 to 2016.

Oncology Gold Standard practical consensus recommendations for the use of monoclonal antibodies in the management of squamous cell carcinoma of head and neck.

We present the 2017 Oncology Gold Standard Practical Consensus Recommendation for use of monoclonal antibodies in the management of advanced squamous cell carcinoma of head neck region.

Human papillomavirus in head and neck cancer in India: Current status and consensus recommendations.

Human papillomavirus (HPV) associated head and neck squamous cell cancers (HNSCC) have become increasingly common in the West, but the same cannot be said about India. These cancers have a different biology and confer a better prognosis, however, its current role in the management of patients in India is not clearly defined. At the 35 Indian Cooperative Oncology Network conference held in September 2016, a panel of radiation, surgical and medical oncologists, pathologists, and basic scientists from across the country having experience in clinical research with respect to HPV in HNSCC reviewed the available literature from India.

Superior vena cava syndrome: A radiation oncologist's perspective.

Superior vena cava syndrome is referred to as a constellation of symptoms and signs caused by obstruction of superior vena cava. It can occur due to both benign and malignant causes with the latter being the predominant. There is a paradigm shift in the approach to manage this condition.

Critical neurological structure sparing radiosurgery of vestibular schwannoma: dosimetric comparison of different techniques and dose prescription methods.

Aim: To investigate potential sparing of critical neurological structures (CNSs) during radiosurgery of vestibular schwannoma (VS) employing different techniques and dose prescription methods.

Materials And Methods: Fused CT and MRI datasets of eight patients with unilateral VS representing a wide range of target volume (0.48 to 12.

AIDS: a radiation oncologist's perspective.

While HIV is often associated with tuberculosis and a number of opportunistic infections, the spectrum of diseases of patients with HIV infection encompasses a number of malignancies as well. Typically, these are the AIDS-defining malignancies, though other malignancies also comprise a significant caseload. Radiotherapy plays an integral part in anti-cancer treatment and its tolerance and efficacy in HIV+ patients are therefore important.

Portal dosimetry for pretreatment verification of IMRT plan: a comparison with 2D ion chamber array.

Portal dosimetry (PD) was performed for 181 fields from 14 IMRT plans of various clinical sites at gantry zero and source-to-detector distance (SDD) of 100 cm. PD was realized using aSi1000 electronic portal imaging device (EPID) and portal dose prediction (PDP) algorithm implemented in Eclipse treatment planning system (TPS). Agreement of PDP predicted and EPID measured photon fluence/dose distribution were evaluated using gamma (γ) index set at 3% at 3 mm distance to point agreement (DTA).

Spinal epidermoid cyst with sudden onset of paraplegia.

Spinal epidermoid cysts, whether congenital or iatrogenic, are relatively uncommon in the spinal cord. When they occur, the typical location is in the subdural, extramedullary space of the lumbo-sacral region. We describe an unusual presentation in a 3-year-old male child which mimicked astrocytoma clinicoradiologically.

Chest wall metastasis from hepatocellular carcinoma in the absence of a primary: An unusual presentation.

Metastatic hepatocellular carcinoma (HCC) has an aggressive course with a very poor outcome. The common hematogenous metastatic sites are the lungs, bones, and adrenal glands. The chest wall is an extremely rare site of metastasis from HCC.

Embryonal rhabdomyosarcoma of the biliary tree mimicking a choledochal cyst.

Embryonal rhabdomyosarcoma (ERMS) of biliary tree is a rare type of mesenchymal neoplasm diagnosed at surgery or by preoperative liver biopsy. We present a one year eight months old child who mimicked a choledochal cyst and was eventually treated with surgery, chemotherapy with IRS IV protocol and adjuvant postoperative radiotherapy to surgical bed with 6 MV photons to a dose of 5040 cGy in 28 fractions.

Recurrent episodes of hematuria: a rare presentation of leiomyosarcoma of prostate.

Leiomyosarcoma of the prostate is an extremely rare entity. Sarcomas account for about 1% of all malignant tumors and less than 5% of them arise from the genitourinary tract. Majority of patients present with urinary obstructive symptoms.
