can we use other factors like 0.1, 0.3 or 0.6 instead of 0.9 as mentioned by Dr. Orthon we are doing gap correction at present only if more than 2 week delay. is it OK? with tdf, upto 7 days break, it will tell no more extra # needed. can we have a copy of the presentation please? if long gaps occured how about giving consideration for rect? can you please send link where i can download the excel and the presetation please Sir what is the K value of other tumours? sir what is the full form of tdf? Thank you sir for sharing excel sheet! will b very helpful Sir pls send link... cant find link on website very lucid presentation,calm & cool.approach why T delay taken as 28 days for all tumour types. different tumour may have different repopulation rates. some head and neck patients , due to reaction treatment interrupted. so managing the gap by giving 2 fractions daily on few days. so how to consider the incomplete repair effects? what are the disadvantages of TDF method? from where this 28 comes? ( 46-28) if gap occurs btw EXBT and Brachy then what are the options? if treatment is planned as EXBT followed by Brachytherapy after 1week but instead of 1wk gap after EXBT gap extended to 2weeks then what are the options? excellent presentation. dear Sir, just to tell you that the total duration in all your examples is 47 days and not 46 days. the presentation is excellent and u are awesome teacher. is it wise to give 2 brachy treatments a day? interesting and excellent presentation can you sent it to me in Thankyou for the amazing tak Sir! What is the largest gap for which correction can be applied? Thank you for nice detailed presentation which website?? please tell the name for a recurrent tumor, if it's just one or two years after complete radiotherapy dose, how to consider dose to be delivered to this site? should we calculate dose decay (K) or what's the appropriate way? Re-irradiation after 5 years on same site can be considered for full dose is what we follow... but for relapse in shorter time period? great presentation sir ,thank u In example treting 5 days, two fractions daily, biological effect must be different. How can it be takes into consideration? Can I know about the validity of LQ model for higher dose per fraction? Thanks sir Good Afternoon Sir If patient treated 4year ago then again recurrent treatment so but gap one week. What I should do sir? When we are hyperfractionating the dose per fraction remains at 200 cGy? Wonderful presentation Prof.Ganesh WHAT ABOUT THE GAP INCASE OF SRT OF BRAIN CONTAINING HIGH DOSE PLEASE TELL WEBSITE ID what is the effect of maximum dose (108%) within PTV volume ? when treating osesphagus PTV of 100 % dose and while cord max point dose is 40% dose .then cord BED ,what is the need for using 100 % dose for calculating cord BED ? what about multiple absents sir Greeting from Colombia, How to consider interruptions of more than 15 days at the end of treatment? in situations where treatment is started and in the first week it is interrupted by the pandemic? Thank you Sir. sir how do we manage months long gaps? What is the acceptable tumour dose per fraction in altered or hyper fraction. E.g head & neck cancer if multiple gap came ,can we use the same model.. Thank you sir, Excellent presentation why 28 is subtracted in BED 10 ?? Cannot see Dr Ganesh slides In the times of IMRT what normal tissue do we consider. Also , normal tissue recovery should be considered or not? very valuable presentation sir what is the effect of increasing dose per fraction on the normal tissue tolerance ? Is there any difference in the calculation for photon and proton ? Good afternoon everyone from Nepal. RCR considerations on accomodating adaptive planning and it's implication in this ? your Opinion plz gap is very common in our place and unfortunately, here is today connection problem. i request you to send me this presentation for later discussion with you if i found problem.
Thank you very much Dr. Gonesh. One of the soulution in the presenation is to alter the dose per fraction, does that mean to replan can you put the website link here Thanks for nice lecture sir
