Background: The FOxTROT trial has reported advantages of neoadjuvant chemotherapy (NAC) in locally advanced colon cancer (LACC). Here we present results of the embedded randomized phase II trial testing the addition of panitumumab to neoadjuvant FOLFOX compared with FOLFOX alone in RAS and BRAF-wild-type patients and with biomarker hyperselction.
Patients And Methods: Patients had operable, CT-predicted stage T3-4, N0-2, M0 colon adenocarcinoma.
Microsatellite instability (MSI) occurs across a number of cancers and is associated with different clinical characteristics when compared to microsatellite stable (MSS) cancers. As MSI cancers have different characteristics, routine MSI testing is now recommended for a number of cancer types including colorectal cancer (CRC). Using gene panels for sequencing of known cancer mutations is routinely performed to guide treatment decisions.

- A clinical trial called RADICALS-HD studied the effects of adding short-course androgen deprivation therapy (ADT) to postoperative radiotherapy in patients with localized prostate cancer after surgery.
- It involved 1480 patients, examining how ADT impacts metastasis-free survival compared to radiotherapy alone, and measured outcomes like distant metastasis and overall survival.
- The trial aimed to see if combining ADT with radiotherapy could improve the 10-year metastasis-free survival rate, potentially increasing it from 80% to 86%.
Article Synopsis
- The study investigates the effectiveness and optimal duration of androgen deprivation therapy (ADT) combined with postoperative radiotherapy for patients with localized prostate cancer following radical prostatectomy.
- A randomised controlled trial, RADICALS-HD, compared short-course ADT (6 months) to long-course ADT (24 months) among participants who met specific criteria, including PSA levels and absence of metastatic disease.
- The primary outcome measured was metastasis-free survival, with the trial aiming to determine if longer ADT duration leads to better survival rates, involving over 1,500 patients from 2008 to 2015.
Background: The optimal timing of radiotherapy (RT) after radical prostatectomy for prostate cancer has been uncertain. RADICALS-RT compared efficacy and safety of adjuvant RT versus an observation policy with salvage RT for prostate-specific antigen (PSA) failure.
Patients And Methods: RADICALS-RT was a randomised controlled trial enrolling patients with ≥1 risk factor (pT3/4, Gleason 7-10, positive margins, preoperative PSA≥10 ng/ml) for recurrence after radical prostatectomy.
