Patient description: The patient is a 41-year-old man and a known case of Acromegaly who underwent transsphenoidal surgery 4 months ago. He came to the clinic for the follow up lab studies after his primary resection surgery. His lab study shows the IGF-1 level of 4.5 ULN adjusted by sex and age. His random GH level is 4 ug/L. The recent brain MRI confirmed the residual pituitary tumor. His past medical history is only significant for acromegaly due to pituitary adenoma and the recent surgery. After his surgery he takes only vitamin D and multivitamins.

Clinical trial eligibility criteria: eligible ages (years): 18.0-99.0,  Colonic Neoplasms Cancer of the Colon Colon Cancer Colon Neoplasms Colonic Cancer In the dose escalation cohorts: Patients must have histologically confirmed malignancy that is metastatic or unresectable and for which standard curative or palliative measures do not exist or are no longer effective. Histology can be based on either the primary tumor or metastases In the MTD expansion cohort: Patients must have biopsy proven K-RAS mutant, metastatic colorectal cancer that has progressed on at least 2 prior standard therapies. K-RAS mutation status must be verified by a CLIA-certified laboratory. (NOTE: colorectal patients enrolled during the dose escalation portion do not need to be K-RAS mutant in order to be eligible) Patients must be at least 4 weeks since prior chemotherapy, 6 weeks if the last regimen included nitrosureas or mitomycin C. Prior radiation is allowed as long as the radiation was completed 4 weeks prior to study treatment and no more than 35% of marrow irradiated Age greater than or equal to18 years. Because no dosing or adverse event data are currently available on the use of AZD6244 in combination with cetuximab in patients less than 18 years of age, children are excluded from this study, but will be eligible for future pediatric phase 1 combination trials ECOG performance status less than or equal to 2 (Karnofsky >60%) Life expectancy of greater than 3 months Patients must have normal organ and marrow function as defined below Leukocytes greater than or equal to 3,000/mcL absolute neutrophil count greater than or equal to 1,500/mcL platelets greater than or equal to 100,000/mcL  Patients who have had chemotherapy, radiotherapy or hormonal therapy within 4 weeks (6 weeks for nitrosoureas or mitomycin C) prior to entering the study or those who have not recovered (less than or equal to grade 1) from adverse events due to agents administered more than 4 weeks earlier Concurrent treatment with an investigational agent other than the investigational agent(s) used in this study OR treatment within 4 weeks of study entry with any investigational agent(s) or device(s) Failure to recover fully (as judged by the investigator) from prior surgical procedures History of allergic reactions attributed to compounds of similar chemical or biologic composition to AZD6244 or other agents used in study Patients taking high doses (more than recommended daily dose) of vitamin E will be excluded. Patients can discontinue use of high dose vitamin E prior to study entry to be considered eligible Any condition (e.g., gastrointestinal tract disease resulting in an inability to take oral medication or a requirement for IV alimentation, prior surgical procedures affecting absorption, or active peptic ulcer disease) that impairs their ability to swallow and retain AZD6244 capsules Patients with malabsorption syndrome, disease significantly affecting gastrointestinal function, or resection of the stomach or small bowel are excluded. Subjects with ulcerative colitis, inflammatory bowel disease, or a partial or complete small bowel obstruction are also excluded Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, uncontrolled hypertension, prior cardiomyopathy, LVEF less than 50%, unstable angina pectoris, cardiac arrhythmia (i.e. atrial fibrillation), or psychiatric illness/social situations that would limit compliance with study requirements Pregnant women are excluded from this study because AZD6244 is a small molecule kinase inhibitor with the potential for teratogenic or abortifacient effects. Because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with AZD6244, breastfeeding should be discontinued if the mother is treated with AZD6244. These potential risks may also apply to other agents used in this study HIV-positive patients on combination antiretroviral therapy are ineligible because of the potential for pharmacokinetic interactions with AZD6244. In addition, these patients are at increased risk of lethal infections when treated with marrow-suppressive therapy. Appropriate studies will be undertaken in patients receiving combination antiretroviral therapy when indicated
