What This Article Covers

1.IISc and MS Ramaiah Medical College found that Low Frequency Ultrasound (LFU) selectively destroys oral cancer cells while sparing normal cells, due to lower levels of the Tropomyosin 2.1 protein in cancer cells.

2.India accounts for 1 in 4 global oral cancer cases, with a five-year survival rate of just 50% compared to 68% in developed nations, highlighting the urgent need for affordable, non-invasive treatments.

3.The novel LFU method, patented by IISc, could be applied to other superficial cancers like breast cancer and melanoma, but concerns about cancer cell spillage during application need further study.

The Big Picture
Prelims · HighMains · Medium

IISc researchers have discovered that Low Frequency Ultrasound (LFU) can selectively kill oral cancer cells without harming normal cells, offering a non-invasive, low-cost alternative for a disease that accounts for 1 in 4 global cases in India. This breakthrough directly addresses India’s low five-year survival rate of 50% and could transform treatment for superficial cancers like oral, breast, and melanoma.

Q1Static LinkageEasy

Which institution led the research on Low Frequency Ultrasound for oral cancer treatment?

Q2Statement-basedHard

Consider the following statements regarding the IISc study on oral cancer:

1. The study used a 3D co-culture platform to mimic the tumour environment.

2. Low Frequency Ultrasound (LFU) generates heat to burn cancer cells, similar to HIFU.

3. The protein Tropomyosin 2.1 is found at lower levels in cancer cells, making them vulnerable to LFU.

Which of the statements given above is/are correct?

Q3Data-centricMedium

According to the article, what is the five-year survival rate for oral cancer in India?

Q4Application/ImpactMedium

What is the primary advantage of Low Frequency Ultrasound (LFU) over High Intensity Focused Ultrasound (HIFU) in cancer treatment?

Merck-Moderna's Personalised mRNA Cancer Vaccine Intismeran Reduces Melanoma Death Risk by 49%

A first-of-its-kind personalised mRNA cancer vaccine (intismeran), developed by Merck and Moderna, combined with Keytruda, has shown a 49% reduction in risk of death from melanoma recurrence and 59% from spread in Phase 3 trials. This marks a breakthrough for cancer vaccines but has limited impact in India due to low melanoma incidence and high cost of immunotherapy.
