Expert Review of Anticancer Therapy
|December 14, 2011
Summary
Significant progress in colon cancer treatment has improved survival for stages IV and III disease. However, high-risk stage II colon cancer patients still need better treatment strategies and predictive biomarkers for improved outcomes.
Area of Science:
- Oncology
- Cancer Research
- Clinical Medicine
Background:
- Colon cancer treatment has seen major advances in the last decade, particularly for stage IV and III disease.
- Surgical resection and perioperative chemotherapy have improved survival for select stage IV patients.
- Adjuvant 5-fluorouracil/oxaliplatin has significantly prolonged survival for stage III patients.
Purpose of the Study:
- To review recent advances in colon cancer treatment.
- To highlight the challenges in treating high-risk stage II colon cancer.
- To emphasize the need for novel therapeutic strategies and predictive biomarkers for stage II disease.
Main Methods:
- Review of recent clinical studies and treatment guidelines for colon cancer.
- Analysis of survival data and treatment outcomes for different stages of colon cancer.
- Discussion of the role of progression-free survival as a surrogate endpoint.
Main Results:
- Survival improvements observed in stage IV (5-50%) and stage III colon cancer.
- Progression-free survival is an established surrogate for overall survival, accelerating clinical integration of new agents.
- Targeted agents show promise in metastatic settings but disappointing results in adjuvant settings so far.
- High-risk stage II colon cancer patients remain a challenging group with poorer prognosis compared to stage IIIA.
Conclusions:
- While significant strides have been made, high-risk stage II colon cancer requires further investigation.
- Current adjuvant treatments have not yielded the same survival improvements for high-risk stage II patients.
- Development of alternative regimens and predictive biomarkers is crucial for improving outcomes in this subgroup.

01:29Drugs for Treatment of Ulcerative Colitis in IBD
Ulcerative colitis is a chronic inflammatory condition primarily affecting the colon and rectum. The primary drugs used in the treatment of ulcerative colitis are aminosalicylates. They exhibit anti-inflammatory and immunosuppressive properties. They modulate inflammatory mediators and inhibit the activity of nuclear factor κB (NF-κB). Aminosalicylates also reduce inflammation by inhibiting prostaglandin and leukotriene production and decreasing neutrophil chemotaxis and superoxide generation.
01:21Drugs for Treatment of Constipation-Predominant IBS
Pharmacological therapies for IBS-C are designed to alleviate abdominal discomfort and enhance bowel function. In patients with IBS-C, fiber supplements may help soften stools and decrease straining, but may also lead to increased gas production and bloating. Osmotic laxatives like milk of magnesia are frequently used to soften stools and increase stool frequency in IBS-C patients. In addition, two drugs approved for use in severe IBS-C adult cases are linaclotide (Linzess) and lubiprostone...
02:49Cancer Therapies
Cancer therapies are various modes of treatment, such as surgery, radiation therapy, and chemotherapy that are administered to cancer patients.
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...

01:27Diverticular Disease of the Colon
Diverticular disease involves the formation of diverticula—small sac-like outpouchings of the colonic wall—and their complications. It most commonly affects the sigmoid colon due to higher intraluminal pressure and structural vulnerability. It results from structural weakness and increased pressure in the colon, producing pseudodiverticula that may remain silent or progress to inflammation and serious complications.Structure of DiverticulaIn diverticulosis, these outpouchings are...
01:20Drugs Affecting GI Tract Motility: Adsorbents as Antidiarrheal Agents
Diarrhea is characterized by the occurrence of frequent, watery bowel movements. Various factors can trigger diarrhea, including viral or bacterial infections, foodborne illnesses, side effects from certain medications, and underlying digestive disorders. If not adequately managed, diarrhea can lead to complications such as dehydration, electrolyte imbalances, and nutrient deficiencies. Severe diarrhea can lead to significant weight loss, malnutrition, and weakened immune function.
