Cited by 23 •
2016
Utilizing patient-derived tumors in a subcutaneous preclinical model is an excellent way to study the efficacy of novel therapies, predictive biomarker discovery, and drug resistant pathways. This model, in the drug development process, is essential in determining the fate of many novel anti-cancer therapies prior to clinical investigation.

2012
Use of Cerenkov Luminescence Imaging (CLI) for monitoring preclinical cancer treatment is described here. This method takes advantage of Cerenkov Radiation (CR) and optical imaging (OI) to visualize radiolabeled probes and thus provides an alternative to PET in preclinical therapeutic monitoring and drug screening.

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...

Anticancer Efficacy of Photodynamic Therapy with Lung Cancer-Targeted Nanoparticles

Photodynamic therapy (PDT) is an alternative choice for lung cancer treatment. To increase the therapeutic effect of PDT, lung cancer-targeted nanoparticles combined with chemotherapy were developed. Both in vitro and in vivo anticancer efficacies of PDT with prepared nanoparticles were evaluated.
FAQs
Treatment selection depends on the tumor’s type, stage, location, and molecular features rather than on a single standard approach. These characteristics help determine whether local treatment, such as surgery or radiation, is appropriate or whether systemic treatment is needed. Molecular information can also support choosing targeted drugs designed to block specific growth signals in malignant cells.
Surgery removes malignant tissue directly, while radiation damages tumor-cell DNA at the treated site. Chemotherapy affects rapidly dividing cells throughout the body. Targeted drugs interfere with selected growth signals, whereas immunotherapy stimulates immune cells to recognize and destroy malignant cells. These distinct mechanisms explain why treatment choice depends on tumor biology and clinical circumstances.
A therapy may produce a tumor response without eliminating every malignant cell, allowing treatment resistance to influence later outcomes. Toxicity is another essential consideration because therapies can affect normal tissues or biological processes as well as cancer cells. Clinical research therefore evaluates both how effectively a tumor responds and how burdensome the treatment is for the patient.
Planning begins by considering the cancer’s type, stage, location, and molecular features, then matching those characteristics with the available therapeutic mechanisms. A plan may focus on removing the tumor, damaging its DNA, blocking growth signals, stimulating immune recognition, or affecting rapidly dividing cells. The selected approach is judged against goals such as control, recurrence prevention, symptom relief, and quality of life.
Evaluation extends beyond whether a tumor becomes smaller. Investigators and clinicians examine tumor response, treatment resistance, toxicity, recurrence, remission, survival, and quality of life. Together, these measures show both biological effectiveness and the broader effect of therapy. A treatment that controls malignancy but causes substantial toxicity may have a different overall value from one with better tolerability.
Therapy provides a framework for studying interactions among malignant cells, treatment mechanisms, and patient outcomes. Researchers compare how tumors respond to DNA damage, growth-signal blockade, immune stimulation, or effects on rapidly dividing cells. They also investigate why resistance develops, how toxicity affects treatment, and which biological features help predict remission, survival, or quality of life.
