Metastatic bone disease ক্যান্সারের advanced stage-এর অংশ—নিজে নিজে bisphosphonate, denosumab, steroid, opioid painkiller শুরু করা বিপজ্জনক। নিচের ডোজগুলো প্রাপ্তবয়স্কদের সাধারণ clinical reference; renal function, calcium level, primary cancer, pain score, pregnancy, age, liver disease অনুযায়ী oncologist/orthopedic oncologist/palliative physician ডোজ বদলাবেন।
1) Metastatic Bone Disease — Definition
Metastatic bone disease / bone metastasis হলো—শরীরের অন্য কোনো জায়গার cancer cell যেমন breast, prostate, lung, kidney, thyroid ইত্যাদি থেকে রক্ত/লিম্ফের মাধ্যমে হাড়ে ছড়িয়ে পড়া। এটি primary bone cancer নয়; অর্থাৎ cancer শুরু হয়েছে অন্য অঙ্গে, পরে হাড়ে এসেছে। Bone metastasis সবচেয়ে বেশি দেখা যায় spine/vertebrae, ribs, pelvis/hip bone, sternum, skull-এ।
Type অনুযায়ী:
- Osteolytic lesion: cancer হাড় ভেঙে দুর্বল করে—fracture risk বেশি; breast, lung, kidney, thyroid cancer-এ common।
- Osteoblastic lesion: abnormal নতুন হাড় তৈরি হয়, bone dense/sclerotic হয়; prostate cancer-এ common।
- Mixed lesion: একই জায়গায় lytic + blastic দুইটাই থাকতে পারে।
2) Cause / কারণগুলো
- Common primary cancer: breast cancer, prostate cancer, lung cancer, kidney cancer, thyroid cancer।
- Multiple myeloma: এটি technically bone marrow plasma cell cancer; bone weakening/lytic lesion প্রায়ই করে।
- Cancer biology: cancer cell bone marrow environment-এ গিয়ে osteoclast/osteoblast activity বদলে দেয়—ফলে হাড় ভাঙে বা abnormal হাড় তৈরি হয়।
- Risk বেশি হয়: advanced stage cancer, previous cancer recurrence, untreated/late-diagnosed cancer, high tumor burden, long-standing cancer-related bone pain।
3) Symptoms — বাংলায় point আকারে
- হাড়ের ব্যথা
- সবচেয়ে common এবং অনেক সময় প্রথম symptom।
- ব্যথা dull ache বা sharp হতে পারে।
- রাতে বেশি, বিশ্রামেও থাকে, ধীরে ধীরে বাড়ে।
- হাঁটলে/নড়াচড়া করলে pain বাড়লে fracture/instability সন্দেহ।
- Swelling / tenderness
- affected হাড়ে চাপ দিলে ব্যথা।
- local swelling থাকতে পারে।
- Pathological fracture
- সামান্য আঘাতেও হাড় ভেঙে যেতে পারে।
- ribs, vertebrae, femur/long bone-এ বেশি গুরুত্বপূর্ণ।
- Spinal cord compression — emergency
- নতুন severe back/neck pain।
- পায়ে weakness/numbness।
- হাঁটতে সমস্যা, balance loss।
- প্রস্রাব/পায়খানা control চলে যাওয়া।
- এগুলো হলে urgent hospital + MRI spine দরকার।
- Hypercalcemia symptoms
- constipation, nausea/vomiting, appetite কমে যাওয়া।
- অতিরিক্ত পিপাসা, বেশি প্রস্রাব।
- confusion, drowsiness, dehydration।
- Bone marrow involvement
- anemia → weakness, breathlessness।
- WBC/platelet কমে গেলে infection/bleeding risk।
4) Clinical diagnosis & investigations — specifically
A) Clinical assessment
- Known cancer history, treatment history, recurrence history।
- Pain history: location, night pain, movement pain, functional pain।
- Full neurological exam: power, sensation, reflex, gait, anal tone, bladder/bowel।
- Long bone fracture risk assessment: Mirels score long bone metastasis-এ pathological fracture risk বোঝার জন্য ব্যবহৃত হয়।
- Spine stability assessment: SINS score spine metastasis stable/unstable বুঝতে সাহায্য করে; 7–12 হলে spine surgeon consultation, ≥13 হলে surgical opinion জরুরি।
B) Blood tests
- CBC: anemia, WBC, platelet।
- Serum calcium + albumin: corrected calcium হিসাব করতে।
- Phosphate, magnesium, ALP: bone turnover/damage clue।
- Renal function: serum creatinine/eGFR—zoledronic acid/NSAID dose safety।
- LFT, albumin।
- Vitamin D level—denosumab/bisphosphonate দিলে hypocalcemia prevention।
- Tumor markers, primary অনুযায়ী: PSA, CA 15-3, CEA, CA-125, thyroglobulin ইত্যাদি।
- Multiple myeloma সন্দেহে: serum protein electrophoresis, urine Bence Jones protein, serum free light chain।
C) Imaging
- X-ray affected bone: fracture/lytic/blastic lesion।
- Bone scan: whole skeleton screen; multiple painful sites থাকলে useful।
- CT scan chest–abdomen–pelvis: primary/extent/staging।
- MRI spine / whole spine: spinal cord compression, marrow involvement, nerve compression—best test।
- PET-CT / PSMA PET: selected cases, especially unknown primary/prostate cancer।
- Biopsy: unknown primary, solitary bone lesion, atypical imaging, infection/primary bone tumor rule out করতে। Imaging tests এবং biopsy diagnosis plan করার জন্য ব্যবহৃত হয়।
5) Complications — সহজ বাংলায়
- Pathological fracture: cancer হাড় দুর্বল করে; সামান্য চাপেই fracture হতে পারে।
- Spinal cord compression: spine metastasis nerve/spinal cord চাপ দিলে paralysis পর্যন্ত হতে পারে—এটি emergency।
- Hypercalcemia of malignancy: রক্তে calcium বেশি হয়ে dehydration, kidney failure, confusion, coma পর্যন্ত হতে পারে।
- Severe chronic pain: ঘুম, হাঁটা, খাওয়া, মানসিক স্বাস্থ্য খারাপ করে।
- Nerve root compression: হাত/পায়ে shooting pain, numbness, weakness।
- Bone marrow failure: anemia, infection, bleeding।
- Reduced mobility: bed sore, DVT, pneumonia risk।
- Treatment complication: bisphosphonate/denosumab থেকে hypocalcemia, kidney issue, osteonecrosis of jaw; opioid থেকে constipation/respiratory depression।
6) Treatment management — overall plan
Metastatic bone disease management সাধারণত multidisciplinary: medical oncologist + radiation oncologist + orthopedic/spine surgeon + palliative care + physiotherapy।
- Primary cancer control: chemotherapy, hormonal therapy, targeted therapy, immunotherapy—primary cancer অনুযায়ী।
- Pain control: WHO analgesic ladder অনুযায়ী paracetamol → NSAID → weak/strong opioid।
- Bone-modifying agent: zoledronic acid বা denosumab—fracture, spinal cord compression, bone surgery/radiotherapy need কমাতে।
- Radiotherapy: painful bone metastasis-এ খুব common; ASTRO guideline অনুযায়ী symptomatic bone metastasis-এ 8 Gy single fraction, 20 Gy/5 fractions, 24 Gy/6 fractions, বা 30 Gy/10 fractions ব্যবহার করা যায়।
- Surgery/fixation: impending fracture, actual fracture, unstable spine।
- Emergency MSCC: immobilization, urgent MRI, dexamethasone, radiotherapy/surgery।

8) Prevention — কীভাবে করবেন
- Known cancer patient হলে নতুন bone pain অবহেলা করবেন না। Night pain, back pain, walking pain, weakness, bladder/bowel problem হলে emergency review।
- Cancer follow-up নিয়মিত: oncologist-এর schedule অনুযায়ী imaging/tumor marker।
- Bone-modifying agent শুরু করার আগে: dental check-up, calcium/vitamin D/renal function check।
- Oral hygiene: দাঁত তুলে ফেলা বা invasive dental procedure করার আগে oncologist/dentist-কে জানান; denosumab/zoledronic acid-এ jaw osteonecrosis risk থাকে।
- Fall prevention: bathroom grab bar, slippery floor avoid, walking aid, good footwear।
- Heavy lifting / forceful massage / bone manipulation avoid—fracture risk থাকলে।
- Physiotherapy: supervised strengthening, mobility training; unstable spine/long bone হলে আগে surgeon opinion।
- Nutrition: adequate protein, vitamin D, calcium—কিন্তু hypercalcemia থাকলে calcium supplement নয়।
- Smoking/alcohol বন্ধ: bone health ও cancer outcome দুইয়ের জন্যই জরুরি।
- High-risk long bone lesion: Mirels score high হলে prophylactic fixation/radiotherapy fracture হওয়ার আগেই করা হতে পারে।
- Spine metastasis: SINS high বা neurological sign থাকলে urgent spine oncology pathway।
