Role of CTV expansion in H & N and Lung primary
Anyone routinely skipping CTV expansions off the GTV (that are taken to the gross disease dose) in the following situations:
1) H&N definitive RT/ChemoRT, omitting a 70Gy 'CTV' expansion of 3-5mm for the primary, in say a Oropharynx patient
2) Same as #1, but for a positive lymph node
3) Definitive chemoRT for lung cancer (NSCLC, LS-SCLC), in regards to the primary
4) Same as #3, but for positive lymph nodes (Source: Student Doctor Network)

Hypopharynx Tis
So, interesting new case...
69 year old patient, who had a pT1 pN0 oropharyngeal cancer a few years ago. He was managed with TORS and neck dissection without adjuvant treatment and remains in remission.
He was now diagnosed with a second primary in the hypopharynx region. It's a rather large lesion but it's spreading superficially.
Biopsy showed only in-situ carcinoma (Tis), no invasive component. The biopsy was quite large/deep and performed at several sites, so I guess it's...

ASTRO releass guidelines for SOC for oropharyngneal XRT
New ASTRO guideline establishes standard of care for curative treatment of oropharyngeal cancer with radiation therapy - American Society for Radiation Oncology (ASTRO)
Am I missing something here? What they published here is exactly what I learned in residency ~ 7 years ago....

RT dose reduction in HPV positive oropharyngeal cancer
Since we had such a great discussion about prostate hypofractionation, I thought we could go over another controversial topic.
David Raben gave an excellent presentation to our residents last year on dose reduction (perhaps to 60 Gy or so with a single cycle of CDDP) for p16 positive oropharyngeal SCC. Logically it makes good sense due to Ang's retrospective finding of better prognosis in these patients.
I'm wondering if any of your institutions are enrolling patients on Phase I/II...
