· Unresectable metachronous metastases, previous adjuvant FOLFOX within the past 12 months: Primary treatment regimens made consistentwith therapy after first progression regimens on page COL-C 1 of 9. The following regimens added: FOLFIRI ± ziv-aflibercept, Irinotecan ±bevacizumab, Irinotecan ± ziv-aflibercept, (Cetuximab or panitumumab) (KRAS WT gene only) + irinotecan.

Regorafenib added as a treatment option in therapy after first, second, or third progression, depending on previous lines of therapy. Bestsupportive care and clinical trial also listed as alternate options to regorafenib.

Regorafenib regimen added: regorafenib 160 mg PO daily days 1-21, repeat every 28 days.

Reference for regorafenib added: Grothey A, Sobrero AF, Siena S, et al. Results of a phase III randomized, double-blind, placebo-controlled,multicenter trial (CORRECT) of regorafenib plus best supportive care (BSC) versus placebo plus BSC in patients (pts) with metastaticcolorectal cancer (mCRC) who have progressed after standard therapies [abstract].

The panel recommends that MMR protein testing be performed for all patients younger than 50 years with colon cancer, based on an increased likelihood of Lynch syndrome in this population. MMR testing should also be considered for all patients with stage II disease, because

PRINCIPLES OF RADIATION THERAPY

··

·

Radiation therapy fields should include the tumor bed, which should be defined by preoperative radiological imaging and/or surgical clips.Radiation doses should be 45-50 Gy in 25-28 fractions.

Consider boost for close or positive margins.Small bowel dose should be limited to 45 Gy.5-FU-based chemotherapy should be delivered concurrently with radiation.

Intraoperative radiation therapy (IORT), if available, should be considered for patients with T4 or recurrent cancers as an additional boost.

Preoperative radiation therapy with concurrent 5-FU-based chemotherapy is a consideration for these patients to aid resectability. If IORT isnot available, additional 10-20 Gy external beam radiation and/or brachytherapy could be considered to a limited volume.

:>

>

>

·

·

·

If radiation therapy is to be used, conformal external beam radiation should be routinely used and intensity-modulated radiation therapy

(IMRT) should be reserved only for unique clinical situations including re-irradiation of previously treated patients with recurrent disease.

Some institutions use arterially directed embolization in select patients with chemotherapy-

resistant/refractory disease, without obvious systemic disease, and with predominant hepatic metastases (category 3).

In patients with a limited number of liver or lung metastases, radiotherapy can be considered in highly selected cases or in the setting of a

clinical trial. Radiotherapy should not be used in the place of surgical resection. Radiotherapy should be delivered in a highly conformal

manner. The techniques can include 3-D conformal radiation therapy, IMRT, or stereotactic body radiation therapy (SBRT) (category 3).

presence and absence of disease progression, including plans for 

adjusting therapy for patients who experience certain toxicities.

Recommended initial therapy options for advanced or metastatic

disease depend on whether the patient is appropriate for intensive

therapy. The more intensive initial therapy options include FOLFOX,

FOLFIRI, CapeOx, and FOLFOXIRI (category 2B). Addition of a biologic

agent (eg, bevacizumab, cetuximab, panitumumab) is either 

recommended or listed as an option in combination with some of these

regimens, depending on available data. Chemotherapy options for 

patients with progressive disease depend on the choice of initial

therapy. The panel endorses the concept that treating patients in a

clinical trial has priority over standard treatment regimens.
