What is the best treatment for a medically inoperable endometrial adenocarcinoma of the uterus FIGO 1, grade 1, type 1?
I would get a pelvic MRI to assess tumor size and myometrial involvement. If small volume (2 cm or smaller) with superficial invasion then use brachy alone, otherwise EBRT plus brachy. The type of brachy is based on uterine width: If the width is less than 5 cm: single tandem and cylinder. Otherwise...
How do you approach adjuvant therapy for resected lung adenocarcinoma that was found unexpectedly postop to be N2?
Preliminary results of the phase 3 randomized LungART trial (NCT00410683) were recently presented at a virtual ESMO conference. 501 patients with pathologically confirmed N2 NSCLC s/p complete resection were randomized to postoperative RT (54 Gy) or observation. Almost all patients received chemothe...
What are your top takeaways in Breast Cancer from ESMO 2025?
ASCENT-03: At ASCO, the results of ASCENT-04 already showed an improvement of PFS (11.2 months vs. 7.8 months) in first-line setting for PD-L1 positive advanced triple negative breast cancer patients treated with sacituzumab plus pembrolizumab compared to chemotherapy plus pembrolizumab. The ASCE...
How do you manage significant gas in patients undergoing pelvic radiotherapy?
This is tough, especially once the simulation is completed, the patient comes in for treatments and now you see very different anatomy. The one thing that I have changed in practice - and I'm aware this is not always possible at higher volume centers - is to have the simulation at about the same tim...
Would you offer upfront radiation for a large painful keloid of the chest that has arisen from an irritated pyoderma gangrenosum lesion?
Radiation therapy is actually used (rarely) for pyoderma gangrenosum that has been unresponsive to medical management via immunosuppression [1]. Single fraction doses of 400 to 800 cGy have been used with slow regression of the lesions. In the case report cited, the lesion started fading after 3 mon...
How do you treat anal adenocarcinoma?
First of all you have to define what you are dealing with. Adenocarcinoma of the anal canal is a rare condition arising from anal glandular tissue. There is no IHC marker or definitive histologic finding that can differentiate it from rectal cancer with extension into the anal canal. The suggestive ...
Does the presence of perineural invasion in early-stage breast cancer post-lumpectomy affect the decision regarding partial breast vs whole breast radiation?
I have not used PNI as a risk factor to change local treatment options after BCS.
What is your preferred treatment for patients with painful gynecomastia on anti-androgen therapy for prostate cancer?
Gynecomastia can be a significant morbidity affecting the quality of life in patients on androgen deprivation therapy, especially in patients who receive bicalutamide as monotherapy or at higher doses such as 150 mg a day. In patients who are younger and/or who may spend time in public without their...
Are you incorporating TTFields into treatment protocols for locally advanced pancreatic cancer based on the PANOVA-3 study?
Most medical and radiation oncologists I have spoken to believe that TTFields offer benefit based on the PANOVA-3 trial and support routine use once it is FDA-approved. One of the outstanding questions relates to the use of definitive radiation therapy, which was not included in either arm, but is a...
What is your approach to uterine perforation during the time of brachytherapy implant for cervical cancer?
First off, I think uterine perforations occur a lot more frequently and easily than we previously accounted for. I learned how to perform brachytherapy using purely orthogonal X-rays, with dosing and dwell position times based on measured distances from the applicators, and all of the focus was plac...
