Inflammatory Bowel Disease V: Surgical Management

320
Surgical interventions for inflammatory bowel disease (IBD), which includes ulcerative colitis and Crohn's disease, are essential in managing symptoms and addressing complications. The selection of surgical procedures is contingent upon the specific conditions and complications that stem from these illnesses.
Here are some common surgical interventions for IBD:

Drugs for Treatment of Ulcerative Colitis in IBD

329
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...

Peptic Ulcer Disease IV: Management

261
Medical treatment strategies for peptic ulcers encompass various methods. The primary goal of treatment is to diminish gastric acidity and strengthen mucosal defense mechanisms.
The therapeutic approach involves ensuring adequate rest, implementing drug therapy, promoting smoking cessation, making dietary modifications, and emphasizing long-term follow-up care.
Pharmacological management
The prevailing therapy for peptic ulcers involves a combination of managing the patient's current...

Cancer Therapies

9.4K
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...

Drugs for Treatment of Crohn's Disease in IBD Using Immunomodulatory Agents

342
Crohn's disease is an inflammatory bowel disorder marked by chronic inflammation of the GI tract. Various treatment strategies for Crohn's disease are employed, such as immunomodulatory agents, glucocorticoids, and biologics or anti-TNF therapy. Azathioprine (Imuran), a commonly used immunomodulatory drug for Crohn's disease, is converted in the body to mercaptopurine, which inhibits purine biosynthesis and cell proliferation. Both are utilized in severe cases of Inflammatory Bowel...

Drugs for Treatment of Crohn's Disease in IBD Using Glucocorticoids

310
Glucocorticoids, a class of anti-inflammatory drugs, are pivotal in treating moderate to severe Crohn's disease by inducing remission. They exhibit their anti-inflammatory action by inhibiting the production of inflammatory cytokines such as tumor necrosis factor (TNF)-α, interleukin (IL)-1, and chemokines like IL-8. In addition, they reduce the expression of inflammatory cell adhesion molecules and inhibit gene transcription of nitric oxide synthase, phospholipase A2, cyclooxygenase-2...

Area of Science:

  • Oncology
  • Gastroenterology
  • Surgical Oncology

Background:

  • Locally advanced rectal cancer (LARC) treatment typically involves trimodality therapy.
  • Variations exist in the sequencing and duration of chemotherapy and chemoradiotherapy around surgery.
  • Emerging strategies include total neoadjuvant therapy (TNT) and non-operative management for select patients.

Purpose of the Study:

  • To review current evidence and controversies in LARC treatment.
  • To incorporate recent updates, including those from the 2020 ASCO annual conference.
  • To provide expert opinion on optimal treatment strategies.

Main Methods:

  • Perspective review of existing literature.
  • Analysis of recent conference updates (2020 ASCO).
  • Expert clinical opinion synthesis.

Main Results:

  • A multidisciplinary team approach is essential for LARC management.
  • Chemoradiotherapy (short or long course) followed by ≥3 months of systemic chemotherapy is a preferred option.
  • Controversy remains regarding doublet vs. triplet chemotherapy regimens.

Conclusions:

  • Optimal sequencing of LARC treatment requires careful consideration of local and distant control.
  • TNT is becoming a standard, necessitating adapted surveillance protocols for early recurrence detection.
  • Resource limitations may impact surveillance effectiveness.
