What Are The Side Effects Of Seed Implants For Prostate Cancer Side Effects and Complications of Seed Implants This CAT scan obtained after a seed implant shows the distribution of the seeds in the prostate gland (red circle) and away from the rectum. Ideally the seeds will be evenly distributed through the gland (except in the center near the urethra) but sometimes they float or bunch up and are not as evenly distributed. This can lead to hot spots (a higher dose than desired) or cool spots (a lower dose than desired.) * * * * * * Short term: most of the patients go home the same day and have mild bladder burning and blood in the urine which usually clears by the next day. Some men have pain in their perineum and benefit from an ice bag. Some men get swelling and obstruction problems (getting the bladder to empty.) Most of the men are sent home with Medrol-Dose-Pak (a steroid to prevent swelling) and Flomax wich can cause dizziness. (Drugs to treat obstruction are as noted: Alpha Reductase Inhibitors: Proscar (finasteride) and Avodart (dutasteride) interfere with the production of a hormone involved with BPH. This can help make the prostate smaller and improve symptoms. Alpha Blockers: Hytrin (terazosin), Cardura (doxazosin), Flomax (tamsulosin) and Uroxatrol(Alfuzosin) all help relax the smooth muscle of the prostate and bladder neck. This helps improve urine flow and reduce the blockage of the bladder.)

From the NCI: “Interstitial implantation of radioisotopes done through a transperineal technique with either ultrasound or CT guidance is being done in carefully selected patients with T1 or T2A tumors. Short term results in these patients are similar to those for radical prostatectomy or external-beam radiation therapy. One advantage is that the implant is performed as outpatient surgery. The rate of maintenance of sexual potency with interstitial implants has been reported to be 86% to 92%, which compares with rates of 10% to 40% with radical prostatectomy and 40% to 60% with external-beam radiation therapy. However, urinary tract frequency, urgency, and less commonly, urinary retention are seen in most patients but subside with time. Rectal ulceration may also be seen. In 1 series, a 10% 2-year actuarial genitourinary grade 2 complication rate and a 12% risk of rectal ulceration was seen. This risk decreased with increased operator experience and modification of implant technique. Short Term Side Effects Immediately after the implant and when the catheter is removed, some men have burning or pressure during urination due to swelling of the gland from the needle punctures. This lasts only a few days. There may also be soreness and bruising behind the scrotal area where the needles were inserted. After a period of two or three weeks further irritation of the gland develops from the radioactivity and the patient may notice burning on urination, pressure, frequency and some slight rectal irritation or diarrhea. The radioactive half life of the seeds (Iodine-125 60 days and Palladium-103 for 17days) measures how long it takes until half the radioactivity wears off. So after 4 half lives (8 months for iodine and 2 months for palladium) the seeds should only have 1/16 or 6% of their radioactivity left (1/2 X 1/2 X 1/2 X 1/2) There is a small risk of acute obstruction (requiring continued use of the Foley catheter) after the implant, particularly if the gland was large or the patient had some obstructive problems (slow urination) already. We generally use Decadron at the time of the implant and Flomax afterwards to lower the risk Long Term Side Effects The risk of urinary problems (frequency or incontinence) is very small, as is the risk of rectal problems. (The risk of a rectal ulcer resulting in a fistula is probably less than 1%, and can be caused by a rectal biopsy after a seed implant.) The risk of impotence is related to age and is higher if the patient also receives external beam irradiation or hormones.A recent review of complications was as noted (Sem Rad Onc 1993;3:240): There are other uncertain risks (e.g. migration of the seeds into the bloodstream and into the lung:) Implications of radioactive seed migration to the lungs after prostate brachytherapy. Ankem Urology 2002 Apr;59(4):555-9 To review the incidence and the impact of pulmonary seed migration after prostate brachytherapy on lung function. Isolated reports of seed migration to the lungs after prostate brachytherapy have been published; however, the clinical consequences of this pulmonary migration have not been adequately evaluated. A total of 83 patients underwent prostate brachytherapy during the study period and 58 patients underwent chest radiography. Seed migration occurred in 21 (36.2%) of 58 patients. Thirty-four (0.71%) of 4755 seeds used migrated to the lungs. Clinical and pulmonary function testing revealed no consistent abnormality attributable to seed migration,

Sample Patient Consent Form RTOG 98-05 RISKS AND DISCOMFORTS Cancer treatments often have side effects. The treatment used in this program may cause all, some, or none of the side effects listed. In addition, there is always the risk of very uncommon or previously unknown side effects occurring. Implant: The possibility exists for infection but this should be controlled with antibiotics should infection occur. There will be soreness in the implant area. The implant itself has the possible side effects of temporary fatigue, diarrhea, abdominal cramps, bladder irritation with some bleeding, incontinence and, in some patients, inability to have an erection. There is also a chance of permanent injury to the bladder, urethra, bowel, and other tissues in the pelvis. The side effects related to the bladder,urethra, and bowel may take some months to years to occur. Another small risk is the movement of a radioactive seed to the lungs. Very small amounts of radiation can reach other people. I should follow the special precautions from my doctor if I’m around small children and pregnant women. Transrectal ultrasound: Other than discomfort, there really is not a great risk from the transrectal ultrasound. CT scan with contrast: An allergic reaction due to the contrast dye could occur but, otherwise, this doesn’t carry any serious risk. Anesthesia: There is the possibility of blood pressure problems, heart rhythm problems, breathing changes, drug reactions, nausea, vomiting, headache, sore throat, heart attack, stroke, or death. Other: There may be some unknown or unanticipated discomforts or risks in addition to those specified above, as this irradiation technique, although not new, is somewhat different from techniques with permanent implantation in the past. Every precaution will be taken to assure my safety to minimize any discomfort that I may experience. Health-related quality of life in men receiving prostate brachytherapy on RTOG 98-05 Feigenberg, IJROBP 2005;62:956 Purpose: To prospectively assess health-related quality of life (HRQOL) during the first year after treatment with prostate brachytherapy (PB) alone for T1c-2a prostate cancer. Materials and Methods: Ninety-eight patients from 24 institutions were eligible and properly entered on this study. All patients were treated with PB alone using I-125 (Oncura Model 6711). The prescription dose was 145 Gy. Three separate health-related quality of life questionnaires (HRQOL) (Functional Assessment of Cancer Therapy-Prostate, Sexual Adjustment Questionnaire, and International Prostate Symptom Score ) were self-administered before and after PB (baseline; 3, 6, 9, and 12 months after PB). The standard error of the mean (SEM) was used to analyze changes in HRQOL scores over time. Patients who improved greater than the SEM were categorized as improved; patients that declined greater than the SEM were categorized as declined; patients were otherwise categorized as stable. All changes are measured using the pretreatment HRQOL score as baseline. Results: The percentage of men who reported the ability to have an erection decreased from 73% at baseline (65% unassisted, 8% assisted) to 57% at 1 year (36% unassisted, 21% assisted), The rate of urinary incontinence increased to 14% at 6 months but had decreased to 1% at the 12-month follow-up. At 1 year after PB, 80% of men reported decreased sexual functioning according to SAQ scores. More than 60% of men reported decreased urinary function at 12 months compared with baseline. Conclusions: This article represents the first prospective, multi-institutional study of HRQOL in men treated with PB and demonstrates that patients undergoing PB have a very high overall HRQOL. The rate of incontinence by 1 year after PB is low, but many patients continue to have obstructive symptoms at 1 year. Although 78% of 1-year respondents state that they can achieve an erection with or without assistance, almost 50% report a decrease in sexual function.

Seed Implant Complications and Adverse Effects

What is the success rate of prostate cancer seed treatments?

Outcomes – As judged by biochemical failure rates, brachytherapy series appear to give comparable or superior disease-specific survival when compared to historical series employing conventional EBRT to treat prostate cancer. Patients must be identified and treated adequately at a recognized facility.

Although brachytherapy is still in its infancy, five-, seven-, and twelve-year follow-up studies indicate that it is comparable to surgery in terms of biochemical recurrence. Ragde et al. reported in a 12-year analysis on patients treated with I-125 seeds with or without additional EBRT that 66% of patients who had brachytherapy alone and 79% of those who underwent brachytherapy + external radiation were free of biochemical or clinical recurrence.

Similarly, Kuban et al. observed no indication of illness in just 64% of I-125-treated individuals at 10-year follow-up, but in all of these patients following prostate biopsy. At 10 years, only 19% of individuals with positive biopsies of the prostate remained actuarially disease-free.

According to a study presented at the European Society for Radiotherapy and Oncology (ESTRO), men with intermediate- or high-risk prostate cancer who are treated with brachytherapy in addition to EBRT had a 9-year progression-free survival rate that is twice as probable. Polascik et al. compared brachytherapy to radical prostatectomy and found that, in similar patients, the progression-free survival rate at 7 years was 87% for surgery and 79% for brachytherapy.

It has been reported that progression-free survival rates for high-risk individuals range from 65 to 80 percent. In evaluating these control rates, factors such as the inclusion of EBRT or androgen ablation and length of follow-up must be carefully considered.

To far, however, no prospective, randomized studies have compared the effectiveness of surgery to that of brachytherapy or high-dose EBRT using recent treatment approaches. Because to a documented shift in stage and histology between biopsy and prostatectomy materials, any retrospective benefit must be taken with caution due to variations in clinical and pathologic staging.

A thorough literature study and statistical analysis conducted by the Prostate Cancer Results Study Group revealed the following:

  • In terms of biochemically-free progression, brachytherapy delivers improved outcomes for diseases with minimal risk.
  • For diseases with an intermediate risk, the combination of EBRT plus brachytherapy looks equal to brachytherapy alone.
  • For high-risk patients, EBRT and brachytherapy plus or without androgen deprivation therapy look better to more targeted treatments such as seed implant alone, surgery alone, or EBRT.

The Partin tables are the most accurate nomogram for predicting the progression and prognosis of prostate cancer.

This part of questions and answers is intended to answer any preliminary inquiries you may have about prostate brachytherapy. Please see your physician for further information and answers to your specific issues. Why wasn’t my doctor aware of brachytherapy as a potential treatment option? Why was he unfamiliar with brachytherapy when I inquired about it? As brachytherapy is a relatively new therapeutic procedure, many physicians are unfamiliar with it.

Some physicians thus only discuss radical prostatectomy (surgical removal of the prostate) and external beam radiotherapy. Men typically learn about brachytherapy via their relatives or the Internet. To the top How does brachytherapy compare to other therapies like as surgery and external radiation beams? The 10-year survival rates of patients who choose brachytherapy or radical prostatectomy are equal, according to clinical data.

Brachytherapy has a lower complication rate than radical prostatectomy, a major surgical procedure, and external beam radiation therapy. The likelihood of lifelong incontinence or impotence seems to be reduced compared to radical prostatectomy. To the top Are all brachytherapy implant seeds identical? No.

Several distinct kind of seeds are utilized in brachytherapy. Seeds of palladium (Pd-103) emit radiation more quickly and for a shorter duration. Some experts believe that palladium seeds are best suited for treating aggressive cancers with a rapid growth rate. Typically, iodine seeds (I-125) are used for the treatment of slow-growing malignancies.

Echogenic seeds have a unique characteristic that aids in the implantation of the seeds into the malignant tissue by the physician. To the top Can the seeds be transmitted by sexual activity or urination? A seed can be transmitted by urine. This often occurs when a seed falls into the bladder.

  1. To avoid leaving seeds in the bladder, many doctors perform a technique called cystoscopy on the bladder following an implant.
  2. If you observe a seed in your urine, your doctor must offer you with advice.
  3. It is also conceivable, but extremely unusual, to transmit a seed during ejaculation.
  4. It is advised that you use a condom during the initial climaxes, as this is when a seed is most likely to be transmitted.

To the top What happens to the prostate’s seeds? Because the seeds lose their radioactive capabilities over time and there is no indication that removing them would be advantageous, they stay in the prostate. To the top How long will the radiation exposure persist, and will I be radioactive following the implant? The radioactivity of the seeds rapidly degrades over time.

  1. Radiation used to treat prostate cancer is administered during the first half-life of the isotope, which for Iodine-125 is 60 days.
  2. The seeds emit radiation with such little energy that it is confined to a millimeter radius around the seeds.
  3. Therefore, despite the fact that extremely sensitive Geiger counters may detect radiation in your body, you would not be deemed radioactive.

Despite the extremely minimal risk, some physicians advise avoiding close contact with pregnant women and young children for a period of time following the initial treatment. Ask your physician for further instructions. To the top How long is the recuperation period following the procedure? In general, healing time is rather brief.

How can you avoid the recurrence of prostate cancer?

10 Considerations for Prostate Cancer Prevention –

  1. Adopt a “anti-inflammatory diet” that is low in red meat, sweets, processed foods, and dairy products and high in anti-inflammatory foods, such as vegetables with vibrant colors.
  2. Consume fewer calories and engage in more physical activity to maintain a healthy weight. It has been demonstrated that vigorous exercise reduces a man’s risk of getting deadly types of prostate cancer, so long as it is performed within the safe limits of his individual fitness level. Obesity is associated with an increased risk of deadly prostate cancer and recurrence of prostate cancer.
  3. Consider your calcium intake. Extremely high calcium intake may raise the risk of aggressive prostate cancer. Unless your doctor advises otherwise, try to acquire the majority of your calcium from plant-based foods (e.g. almonds, tofu, leafy greens) rather than supplements.
  4. Substitute plant-based proteins and seafood for red meat. Red meat’s saturated fat causes inflammation, which is linked to cancer and other chronic illnesses. Stay away from trans fatty acids (e.g., margarine, packaged baked goods).
  5. Incorporate potentially beneficial cooked tomatoes (made with olive oil) and cruciferous vegetables (such as broccoli and cauliflower) into several of your weekly meals.
  6. Avoid smoking for a variety of reasons. Consume alcohol sparingly, if at all.
  7. Stress, high blood pressure, diabetes, high cholesterol, and depression should be treated medically. Treating these diseases might save your life and increase your chance of surviving prostate cancer.
  8. Megavitamin oversupplementation should be avoided. Although multivitamins are unlikely to be dangerous, if you consume a diet rich in fruits, vegetables, whole grains, seafood, and healthy oils, you probably do not require them. Consult your physician regarding herbal supplements, since some may be harmful or conflict with your medication.
  9. Relax and appreciate life. Reducing stress at work and at home will increase your survival rate and lead to a longer, happier life.
  10. Discuss the risks and advantages of screening with a PSA test and, if necessary, a rectal exam with your doctor if you are a man aged 45 or older (40 or older for Black men or those with a family history of prostate cancer).
  • A few easy modifications to your everyday diet can help you live a better lifestyle as you recover from prostate cancer, and may even.
  • Infection, Bacteria, and Inflammation Cancer? What was that? Urine’s not sterile! This may be terrible news for folks like Bear Grylls, a TV survival expert who frequently.

A 17-year prostate cancer-specific survival (PCSS) rate of 97% was determined by the research. According to the American Cancer Society, the inclusion of brachytherapy to EBRT improves patient outcomes in comparison to EBRT alone. Brachytherapy enhances the 9-year survival rate for patients with intermediate to high-risk cancer from 62% to 83%.

Are radiation seeds beneficial against prostate cancer?

The quantity of radiation remaining in the seeds is so minute that it has no impact on the body. Permanent seed brachytherapy is equally effective as surgery or external beam radiation for the treatment of low-risk prostate cancer.

Long-term survival statistics for patients with advanced prostate cancer imply that they may be suitable surgical candidates, according to experts at the Mayo Clinic. Eighty percent of individuals diagnosed with cT3 prostate cancer, which has the potential to spread beyond the prostate, and treated with radical prostatectomy, or surgery to remove the prostate gland, had a 20-year survival rate.

  1. In the past, individuals with cT3 prostate cancer were only provided radiation or hormone therapy, but not radical prostatectomy.
  2. The researchers presented their findings at the annual meeting of the American Urological Association in Washington.R.
  3. Jeffrey Karnes, M.D., of the Mayo Clinic’s Department of Urology, explains, “We’re doing a lot better job of finding and broadening surgical candidates, resulting in better, longer outcomes for so many of our patients.” We have confirmed that individuals with locally advanced prostate cancer can experience a lengthy cancer-free period.

The 20-year survival rate for cT3 prostate cancer is 80 percent, compared to 90 percent for cT2 prostate cancer. This long-term follow-up of patients who underwent surgery between 1987 and 1997 is a significant step forward in our understanding of the quality of outcomes for cT3 patients.

  • Patients diagnosed and operated on between 1987 and 1997 made up the research sample.
