Do you treat inguinal lymph nodes for patients with low lying vaginal cancers?
Do you use SIB or sequential approach? Do size of lymph nodes influence your dose or decision?
Answer from: Radiation Oncologist at Academic Institution
Yes we do. For distal vaginal cancers (not involving vulva) that have no enlarged nodes, we treat the medial inguinal nodes (e.g. nodes medial to the common femoral and saphenous veins) to 45 Gy. We do not treat the nodes lateral to the femoral vein (i.e., along the circumflex v) unless there are su...

I agree entirely. Total treatment time is extremely important and it is for this reason that we usually integrate a boost for large nodes although we rarely exceed 210 cGy per fraction if there are critical structures close by (particularly duodenum). It sounds like Sushil and I are fairly close in ...

Yes we do treat bilateral inguinal nodes for distal vaginal cancers. For involved nodes we use SIB technique of 55Gy in 25 fractions for nodal size up to 2 cm. For larger nodes, we add two or three additional fractions.
Our outcome data using this approach for cervical cancer is published in Red Jo...

Only one minor comment I would make about EQ2 for 55 Gy in 25 fractions when calculated without taking total treatment time is 56 Gy as mentioned but if we consider that treatment is done in 5 weeks instead of 6 weeks then depending on what Tpot we consider for calculation it varies from 58-60 ...
