It describes the borders of the mesorectum and lists the lymph node regions included in the CTV for involved nodes. It concludes by specifying the planning target volumes (PTVs) which expand the CTVs and listing the dose schedules.
TARGET DELINEATION IN ANAL CANAL CANCER BY DR KANHU
1. The document discusses target delineation and radiation therapy workflow for anal cancer, including definitions of gross tumor volume (GTV) and clinical target volumes (CTVs) based on anatomical locations.
2. It provides guidelines for determining margins around the GTV and nearby anatomical structures to create the CTVs for the primary tumor (CTVp), involved nodes (CTVn), and elective nodal regions (CTVnLR) to cover possible microscopic disease.
3. Treatment planning volumes (PTVs) are created by adding margins to the CTVs, with the PTV-HR receiving the full prescription dose and the PTV-LR receiving a lower dose.

Key findings are that chemoradiation improves local control and survival as adjuvant or radical therapy, and brachytherapy and external beam radiation are effective for palliation. Optimal regimens involve fluorouracil or capec
FEBRUARY 2024 ONCOLOGY CARTOON /95TH VOLUME

WHY STEREOTATXY IN CRANIAL AVM / DR KANHU CHARAN PATRO
This document discusses stereotactic radiosurgery (SRS) for the treatment of cerebral arteriovenous malformations (AVMs). It begins by explaining what an AVM is and the risks they pose if untreated, such as bleeding in the brain. It then covers treatment options for AVMs and why SRS is often preferred for certain cases, such as when the AVM is in an eloquent or deep brain area. The document provides details on patient selection, imaging and planning for SRS, anticipated outcomes, and risks of treatment complications. It emphasizes the importance of multidisciplinary discussion and informed consent when determining if SRS is appropriate for a patient's individual AVM.
PORTAL VEIN TUMOR THROMBOSIS SBRT/DR KANHU CHRAN PATRO
1) SBRT is an effective treatment for hepatocellular carcinoma (HCC) patients with portal vein tumor thrombosis (PVTT). In a study of 70 HCC patients with PVTT treated with SBRT, median survival was 10 months and 6-month and 12-month survival rates were 67.3% and 40% respectively.
2) Patients who received SBRT combined with transarterial chemoembolization (TACE) had significantly longer survival compared to those who did not receive TACE after SBRT.
3) SBRT is a promising bridging therapy prior to liver transplantation or hepatectomy by downstaging PVTT to make these curative procedures possible.
DR KANHU CHARTAN PATRO/ FOR ENT SURGEONS
1. Radiotherapy plays a crucial role in the treatment of head and neck cancers, both as a primary treatment and in combination with surgery. It is used for cancers of the nasopharynx, larynx, hypopharynx, and as postoperative treatment for most oral cancers.
2. Advances in radiotherapy technology such as IMRT have allowed for better tumor targeting while minimizing doses to surrounding healthy tissues, reducing treatment toxicities. Imaging techniques such as PET-CT provide improved visualization of tumors and affected lymph nodes, helping determine accurate target volumes.
3. Organ preservation approaches using radiotherapy and chemotherapy are increasingly used to treat head and neck cancers, avoiding disfiguring surgeries while achieving high

Here are the key points about the hepatitis B vaccine and liver cancer:
- Hepatitis B virus (HBV) infection can lead to chronic hepatitis B and significantly increase the risk of developing liver cancer later in life.
- The hepatitis B vaccine is effective at preventing HBV infection and therefore helps prevent liver cancers caused by the virus. It was the first vaccine referred to as an "anti-cancer" vaccine by the FDA.
- Around 25% of people with chronic HBV infection may develop liver cancer according to the CDC. Getting vaccinated helps avoid this risk.
- The hepatitis B vaccine is available and affordable in India, ranging from around 45 rupees per pediatric dose to 250 rupees for the
DEBATE IN CA BLADDER TMT VS CYSTECTOMY
1) Dr. KanhuCharanPatro is a radiation oncologist who specializes in stereotactic radiation oncology for treating cancers like urinary bladder cancer.
2) The document discusses trimodal therapy (TMT) versus radical cystectomy (surgery to remove the bladder) for treating urinary bladder cancer, citing evidence from studies that TMT may provide comparable survival outcomes to cystectomy with fewer side effects and better quality of life.
3) A meta-analysis of over 50,000 patients found that TMT had non-inferior overall survival rates to cystectomy at over 10 years and may be a reasonable alternative for patients who cannot undergo or do not want surgery.
ROSE CASE CARDIAC ARRHYTHMIA SBRT
1) Stereotactic arrhythmia radioablation (STAR) is a non-invasive technique using SBRT to treat refractory ventricular tachycardia (VT).
2) The first human case was reported in 2015 where a single fraction of 33Gy targeted to the scar substrate significantly reduced the VT burden.
3) Target delineation involves multimodality cardiac imaging including CT, MRI, nuclear imaging and electroanatomical mapping to identify and track the scar substrate through the cardiac cycle.
NOV 2023 ONCOLOGY CARTOONS
This document discusses contrast clearance analysis (CCA) for differentiating tumor recurrence from radiation necrosis in brain tumors. CCA analyzes contrast enhancement on MRI scans obtained minutes and hours after contrast administration. Tumor tissue shows effective contrast clearance over time and appears blue on CCA, while necrotic tissue accumulates contrast and appears red. CCA has shown high diagnostic accuracy for this differentiation compared to standard MRI. The document provides examples of CCA images for different types of brain lesions, demonstrating the visualization of tumor versus reactive tissue.
SRS SBRT WORKFLOW.pptx
This document discusses the management of diffuse gliomas and outlines the workflow for stereotactic radiosurgery (SRS) and stereotactic body radiation therapy (SBRT). It covers topics such as target delineation, motion management, dose prescription, plan evaluation, quality assurance, and the importance of education. Strict immobilization and minimizing errors are emphasized for SRS and SBRT. Various motion management systems and techniques for different tumor sites are presented. Metrics for evaluating plan quality like coverage, conformity, homogeneity and dose to organs-at-risk are defined. The document stresses the need to balance optimal target coverage while restricting dose to nearby organs.
CARING OF BEDRIDDEN PATIENTS
This document provides guidance for caretakers of neurological or bedridden patients.

It is intended to be accessible to help as many people as possible care for neurological patients.
RADIATION PROCEDURE ADVICE FOR PATIENTS
Radiation is a simple procedure that requires patient cooperation. It typically involves mask preparation, CT planning scans, and 15 minute daily sessions for 4-7 weeks. Diet, hydration, avoiding smoke/alcohol, and meeting with doctors weekly are important. Common side effects like skin darkening are usually temporary, while complications like pneumonia are very rare. Follow-up visits assess tumor response and determine any additional treatment.

Overall life span (LS) was 1671.7±1721.6 days and cumulative 5YS reached 62.4%, 10 years – 50.4%, 20 years – 44.6%. 94 LCP lived more than 5 years without cancer (LS=2958.6±1723.6 days), 22 – more than 10 years (LS=5571±1841.8 days). 67 LCP died because of LC (LS=471.9±344 days). AT significantly improved 5YS (68% vs. 53.7%) (P=0.028 by log-rank test). Cox modeling displayed that 5YS of LCP significantly depended on: N0-N12, T3-4, blood cell circuit, cell ratio factors (ratio between cancer cells-CC and blood cells subpopulations), LC cell dynamics, recalcification time, heparin tolerance, prothrombin index, protein, AT, procedure type (P=0.000-0.031). Neural networks, genetic algorithm selection and bootstrap simulation revealed relationships between 5YS and N0-12 (rank=1), thrombocytes/CC (rank=2), segmented neutrophils/CC (3), eosinophils/CC (4), erythrocytes/CC (5), healthy cells/CC (6), lymphocytes/CC (7), stick neutrophils/CC (8), leucocytes/CC (9), monocytes/CC (10). Correct prediction of 5YS was 100% by neural networks computing (error=0.000; area under ROC curve=1.0).
