Targeted Cancer Therapies

9.0K
The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.
There are several types of targeted therapies against...

Combination Therapies and Personalized Medicine

6.3K
Combining two or more treatment methods increases the life span of cancer patients while reducing damage to vital organs or tissue from the overuse of a single treatment. Combination therapy also targets different cancer-inducing pathways, thus reducing the chances of developing resistance to treatment.
The combination of the drug acetazolamide and sulforaphane is a good example of combination therapy to treat cancer. The cells in the interior of a large tumor often die due to the hypoxic and...

Peptic Ulcer Disease IV: Management

599
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...

Pharmacogenetics of Drug Targets: β₂-Adrenergic Receptors, Apo E, Thymidylate Synthase

60
Genetic polymorphisms in drug targets have emerged as critical determinants of interindividual variability in drug response and toxicity. Pharmacogenomic investigations increasingly focus on identifying these variations to personalize and optimize therapeutic interventions. A drug target may be a receptor, enzyme, or signaling protein involved in pharmacologic responses or disease-related pathways. While early pharmacogenetic studies focused primarily on drug metabolism, current research...

Summary

Optimal systemic therapy for advanced gastric adenocarcinoma (GAC) involves platinum/fluoropyrimidine combinations, with trastuzumab for HER2-positive tumors. Second-line treatment favors paclitaxel/ramucirumab, guiding advanced GAC management.

Area of Science:

  • Oncology
  • Gastroenterology
  • Pharmacology

Background:

  • Gastric adenocarcinoma (GAC) is a leading cause of cancer mortality globally.
  • Advanced GAC is generally incurable, necessitating effective systemic therapies.
  • Current targeted treatments are limited, highlighting the need for optimized regimens.

Purpose of the Study:

  • To review and define optimal systemic therapy strategies for advanced gastric adenocarcinoma.
  • To consolidate evidence from phase II-III studies for current treatment guidelines.
  • To identify emerging therapeutic targets based on molecular classifications.

Main Methods:

  • Comprehensive literature search of phase II-III studies on advanced GAC.
  • Inclusion of data from major databases (PubMed, clinicaltrials.gov) and oncology society proceedings (ASCO, ESMO).
  • Expert commentary synthesizing findings for clinical application.

Main Results:

  • First-line therapy recommendation: platinum compound plus fluoropyrimidine.
  • Addition of trastuzumab is advised for HER2-positive GAC.
  • Second-line therapy preference: paclitaxel/ramucirumab over ramucirumab monotherapy.

Conclusions:

  • Systemic therapy for advanced GAC requires tailored approaches based on tumor characteristics.
  • Established first- and second-line regimens provide a framework for treatment.
  • Further research into molecular and immune biology is crucial for novel therapeutic targets.
