Recent research conducted at the Jamilur Rahman Centre for Genomic Research at the University of Karachi has unveiled a concerning issue: many imported chemotherapy drugs, particularly those used to treat breast cancer, are largely ineffective for Pakistani patients. (The Tribune)

Genetic Differences Impacting Treatment Efficacy

The crux of the problem lies in the genetic disparities between Pakistani populations and those in Western countries, where these chemotherapy drugs are developed and tested. Dr. Ishtiaq Ahmed, Associate Professor at the University of Karachi’s International Centre for Chemical and Biological Sciences (ICCBS), emphasized that these genetic differences significantly influence how patients respond to treatment. He noted that clinical trials for these drugs are conducted in Western countries without considering these genetic variations, leading to reduced efficacy in Pakistani patients. (The Tribune)

Alarming Statistics on Breast Cancer in Pakistan

Pakistan faces a high incidence of breast cancer, ranking seventh in South Asia for breast cancer cases and fifth in mortality rates. Notably, breast cancer is predominantly diagnosed in Pakistani women aged between 30 to 45 years. Despite this, treatment guidelines and data are often extrapolated from European countries, overlooking the unique genetic and demographic characteristics of the Pakistani population. (The Tribune)

The Need for Population-Specific Research

The study underscores the urgent need for comprehensive research to develop cancer treatments tailored to Pakistan’s genetic makeup. Dr. Ahmed highlighted that their experiments demonstrated significantly lower efficacy of a well-known chemotherapy drug on Pakistani breast cancer cell lines compared to European ones. This finding calls for large-scale studies to identify effective treatments that align with the genetic profiles of Pakistani patients. (The Tribune)

Challenges Beyond Drug Efficacy

Beyond genetic factors, Pakistani women encounter additional barriers in breast cancer diagnosis and treatment:

• Cultural and Religious Taboos: Many women are reluctant to seek treatment from male physicians due to cultural norms and religious values, leading to delays in diagnosis and care. (pmc.ncbi.nlm.nih.gov)
• Financial Constraints: The high cost of cancer treatment poses a significant obstacle, especially for those from lower socioeconomic backgrounds, resulting in postponed or forgone medical attention. (pmc.ncbi.nlm.nih.gov)

Moving Forward: A Call to Action

Addressing these challenges requires a multifaceted approach:

• Genetic Research: Investing in studies that explore the genetic landscape of Pakistani populations to develop effective, personalized cancer treatments.
• Awareness Campaigns: Implementing educational programs to dispel cultural stigmas associated with breast cancer, encouraging women to prioritize their health and seek timely medical advice. (sputnikglobe.com)
• Financial Support Systems: Establishing assistance programs to alleviate the economic burden of cancer treatment, ensuring accessibility for all socioeconomic groups.

By acknowledging and addressing these unique challenges, Pakistan can enhance the effectiveness of breast cancer treatments and improve outcomes for countless women nationwide.
