New clues to why colon cancer is harder to treat in younger people

نوجوانوں میں بڑی آنت کے کینسر کا علاج مشکل کیوں؟ نئی تحقیق میں اشارے مل گئے

युवाओं में कोलन कैंसर का इलाज कठिन क्यों है, नए संकेत मिले

New clues to why colon cancer is harder to treat in younger people

Key points

اہم نکات

मुख्य बातें

  • Researchers studying 189 colorectal tumour samples have found new clues to why the cancer can be more aggressive in younger patients.
  • Tumours in people under 50 had a higher share of connective and supporting cells, which can shield tumours from immune cells and drugs and have been linked to chemotherapy resistance in other cancers.
  • Younger patients' tumours also showed different gene activity and stronger signals between cells that may help cancer spread.
  • 189 بڑی آنت کے کینسر کے نمونوں کی تحقیق سے نوجوان مریضوں میں اس بیماری کے زیادہ شدید ہونے کی نئی وجہ سامنے آئی ہے۔ 50 سال سے کم عمر کے مریضوں کے ٹیومرز میں جڑنے والی اور مدد کرنے والی خلیوں کی مقدار زیادہ تھی، جو ٹیومر کو مدافعتی خلیوں اور دواؤں سے بچا سکتی ہیں اور دیگر کینسرز میں کیموتھراپی کے خلاف مزاحمت سے منسلک رہی ہیں۔ نوجوان مریضوں کے ٹیومرز میں جینز کی سرگرمی بھی مختلف تھی اور خلیوں کے درمیان سگنل زیادہ مضبوط تھے جو کینسر کے پھیلنے میں مدد کر سکتے ہیں۔ نیچر میڈیسن میں شائع ہونے والی یہ تحقیق ابھی یہ ثابت نہیں کرتی کہ یہ فرق ہی خراب نتائج کی وجہ ہے، لیکن ماہرین کا کہنا ہے کہ اس سے مستقبل کے علاج کی نئی سمت ملی ہے۔
  • कोलोरेक्टल ट्यूमर के 189 नमूनों के अध्ययन से युवा मरीजों में कैंसर के अधिक आक्रामक होने के नए संकेत मिले हैं। 50 वर्ष से कम उम्र के मरीजों के ट्यूमर में संयोजी और सहायक कोशिकाओं की मात्रा अधिक थी, जो ट्यूमर को प्रतिरक्षा कोशिकाओं और दवाओं से बचा सकती हैं और अन्य कैंसर में कीमोथेरेपी प्रतिरोध से जुड़ी रही हैं। युवा मरीजों के ट्यूमर में जीन गतिविधि भी अलग थी और कोशिकाओं के बीच संकेत मजबूत थे, जो कैंसर के फैलने में मदद कर सकते हैं। नेचर मेडिसिन में प्रकाशित यह अध्ययन अभी यह साबित नहीं करता कि यही अंतर खराब परिणामों का कारण है, लेकिन विशेषज्ञों का कहना है कि इससे भविष्य के इलाज के लिए नई दिशा मिली है।

Researchers studying 189 colorectal tumour samples have found new clues to why the cancer can be more aggressive in younger patients. Tumours in people under 50 had a higher share of connective and supporting cells, which can shield tumours from immune cells and drugs and have been linked to chemotherapy resistance in other cancers. Younger patients' tumours also showed different gene activity and stronger signals between cells that may help cancer spread. The study, published in Nature Medicine, does not yet prove these differences cause worse outcomes, but experts say it gives researchers a new direction for future treatments.
