Lu-177 PSMA Therapy — For Advanced Prostate Cancer

That is the whole idea in one line: instead of aiming a machine at one area from outside, the radiation travels in the bloodstream and sticks where the cancer is. It belongs to a family of treatments called theranostics — the same target used to see the disease on a scan is the one used to treat it.

This page exists because most of what is written about Lu-177 PSMA online is either a research abstract or marketing copy. Neither answers what a family in Hyderabad actually needs to know before a first appointment. So the three sections below take the three questions in the order they are usually asked: am I eligible, how long does this go on for, and what will it do to me.

Lu-177 PSMA therapy is delivered at an NABH-accredited partner nuclear medicine centre; CION Cancer Clinics coordinates your treatment plan, your oncology team and your care throughout. CION does not own or operate a nuclear medicine facility, a linear accelerator or any other radiotherapy equipment.

The scan is the part most families do not expect. A PSMA PET-CT is not simply a staging scan here — it is the eligibility test itself. If the deposits do not light up, the therapy has nothing to attach to, and no amount of willingness to pay changes that. This is why a treating team will not commit to the treatment before the scan is done and read.

What a team is usually looking for

• Prostate cancer that has spread beyond the prostate and is still progressing on hormone-directed treatment.
• A recent PSMA PET-CT showing strong tracer uptake across the sites of disease.
• Kidney function within the range your nuclear medicine team accepts, since the isotope clears through the kidneys.
• Blood counts — haemoglobin, white cells and platelets — high enough to tolerate a course.
• Fitness to sit through an infusion and to follow radiation-safety instructions at home afterwards.
• A tumour board or treating team decision, made with your urologist, medical oncologist and nuclear medicine physician together.

What usually makes it unsuitable

• Sites of disease that do not take up the tracer on the PSMA PET-CT, or a mixed picture where major deposits are cold.
• Kidney function or blood counts below the treating centre's threshold, at least until they recover.
• Very poor general fitness, where the burden of travel and infusions outweighs any likely benefit.
• Untreated urgent problems, such as spinal cord compression, that have to be dealt with first.

Guideline bodies including NCCN place this treatment in the advanced, previously treated setting rather than as a first step. It is not an alternative to surgery or to standard radiation for localised prostate cancer.

Six is a plan, not a promise. Each cycle is a fresh decision, and the decision is made on your reports rather than on the original number. Here is what one cycle actually involves.

If you are coordinating for a relative from another city or from abroad, plan around the cycle rhythm rather than a single trip: one hospital day roughly every six weeks, with a few restricted days at home after each.

This list is what is commonly reported and discussed in ASTRO and NCCN patient guidance. It is not exhaustive, and your written consent discussion at the partner centre is where the full list for your dose is covered. Call your team the same day for fever, bleeding, sudden severe pain, or a drop in how much urine you are passing.

This is the single biggest practical difference between radioisotope therapy and the daily radiation most people picture. There is no machine and no mask, but there is a short window at home where distance matters. The rules are simple, they are temporary, and they are written down with dates — follow those dates rather than a general figure from a forum.

Depending on the centre's protocol and your dose, you may be observed in a dedicated shielded room before discharge. Our guide to the isolation room stay during radioisotope therapy covers what that room is like and what to carry, and living with someone after radioisotope therapy covers the household rules once you are home.

Attendants and family members are not at risk when they follow the written distance and hygiene instructions. Ask the nuclear medicine team to explain the sheet to whoever will actually be at home with you, not only to the patient.

In practice, the sequence is: a consultation and record review, a PSMA PET-CT at a partner imaging centre, a treating-team decision on eligibility, and then a scheduled first cycle. Slot availability depends on scan bookings and on isotope stock at the partner centre, so dates are confirmed rather than assumed — ask for them in writing.

If you are coordinating from outside Hyderabad

Families arranging care for a father or brother from another city, or from overseas, usually want to know how much travel is unavoidable. Scan reports and prior records can be reviewed remotely before anyone books a ticket, which means the eligibility conversation happens before the journey rather than after it. Once a course starts, plan one hospital day roughly every six weeks, with a few restricted days at home after each cycle.

What about cost?

Radioisotope therapy is quoted per cycle rather than as a single package, and the PSMA PET-CT scans are billed separately from the treatment itself. Because the number of cycles you actually receive is reviewed as you go, the total is a range, not a fixed figure. Any estimate you are given is indicative, as of August 2026, and shifts with the centre, the scan protocol and stock availability. Our page on the cost of theranostics and radioisotope therapy in India sets out what an itemised estimate should contain and what insurance and government schemes typically do and do not cover.

Ask for a written, itemised estimate naming what is included — scans, infusion, room, monitoring, follow-up — before you commit to a course.

• New to the whole idea of radioactive medicine? Start with theranostics: treatment with radioactive medicine explained, which covers why a scan and a treatment can share the same target.
• Worried about the money before the medicine? Cost of theranostics and radioisotope therapy in India explains how these treatments are quoted and what to check in an estimate.
• Told you may need a shielded room? The isolation room stay during radioisotope therapy describes the room, the rules and what to carry.
• Going home to a full house? Living with someone after radioisotope therapy: household rules covers sleeping, toilets, laundry and children.
• Want the wider picture? Our radiation therapy hub sets out how external beam radiation, brachytherapy and radioisotope treatments are each planned and coordinated with NABH-accredited partner centres.
