It was a big year for rectal cancer treatment! PROSPECT (Deb Schrag et al.,) - for selected “high” rectal cancers we can likely omit radiation if they have a good response to FOLFOX. Notable exceptions: tumors that require an APR, are stage T4 or N2. About 10% of patients will not have ...

There were 3 studies with a clear message on what should not be done outside of clinical trials OR should be used judiciously. NeoCol, (oral colon session) - Negative study for neoadjuvant chemotherapy in patients with resectable colon cancer. Message: neoadjuvant therapy for colon cancer should on...

PROSPECT study: This study enrolled 1,194 locally advanced rectal cancer patients (main inclusion criteria: ECOG 0-2, age >=18, T2N+ or T3N+/-, eligible for sphincter preserve surgery at initial diagnosis, tumor is not within 3 mm of the radial margin). There, patients were randomized 1:1 to tw...

PROSPECT: phase III study of neoadjuvant chemoradiation vs neoadjuvant FOLFOX CT with or without chemoradiation for patients with locally advanced rectal cancer (abstract LBA2). NORPACT-1: randomized phase II study of short-course neoadjuvant FOLFIRINOX vs upfront surgery for patients with resect...

PROSPECT: A randomized phase III trial of neoadjuvant chemoradiation versus neoadjuvant FOLFOX chemotherapy with selective use of chemoradiation, followed by total mesorectal excision (TME) for treatment of locally advanced rectal cancer (LARC) (Alliance N1048).This study was simultaneously presen...

PROSPECT: In patients with locally advanced rectal cancer that were also eligible for sphincter sparing surgery, neoadjuvant FOLFOX with selective use of 5FU CRT was non inferior to 5FU CRT with regards to DFS. This randomized phase 3 trial is practice-changing and empowers patients by giving them...

Clearly, the most impactful trial was the PROSPECT trial. Coupled with the increasing amount of data showing that some patients with locally advanced rectal cancer can successfully be treated without surgery (the so-called "watch and wait" approach), this demonstrates that we are now able to offer...
