Often, skin rash is noted in the sun exposed parts of the body, such as the face or chest. Oral antibiotics may be needed for worsening skin rash, such as one accompanied with blisters and ulcers. LESSONS LEARNED: Panitumumab has no clinical activity in metastatic RAS wild-type small bowel adenocarcinoma (SBA) and ampullary adenocarcinoma (AAC), possibly due to the foregut and midgut derivation of small bowel and ampulla.These results, along with findings from genomic characterization of SBA, suggest that SBA represents a unique intestinal malignancy and treatments should not be habitually extrapolated from colorectal cancer.Further studies evaluating the benefit of targeted therapies PMID: 26504047. Abstract. Background: Although the anti-EGFR monoclonal antibody panitumumab is effective in treating colorectal cancer, the occurrence of severe skin disorders often discontinues therapy.
