PURPOSE: This study was performed to define the rectal dose constraint that would predict late rectal bleeding requiring argon plasma coagulation APC following prostate brachy mono-therapy. Rectal volumes were contoured on the T2 weighted MR images. For those patients requiring APC, the date on which a patient reported rectal bleeding was recorded. A Cox regression analysis was performed to assess whether there was a significant association between the rectal volume continuous exceeding Gy time rectal bleeding. Comparisons of estimates of rectal bleeding requiring APC were made using a 2-sided log rank test.

Treatment options depend on many factors. You should discuss your treatment options with your primary care doctor, urologist, and radiation oncologist. Prostate seed implantation PSI is a type of radiation therapy that involves placing radioactive seeds into the prostate. PSI delivers a high dose of radiation to the prostate gland and sometimes the seminal vesicles, which lie on either side of the prostate gland.
Your doctors have decided that you are a candidate for PSI. The type of radioactive sources used in PSI come in the form of metallic seeds, about the size of a grain of rice. The number of seeds needed to treat your cancer is determined by the size of your prostate gland and the dose of radiation being used. Typically, between 70 and seeds are placed at one time. The seeds give off their radiation slowly over several months.
Within one year, the radioactivity can be considered gone; however, the metallic seeds will remain in your prostate gland. You will need to have a special ultrasound before your implant. It is done by placing a probe in your rectum to view the prostate gland.
This will allow the doctor to take measurements and plan for the PSI. Your radiation oncology nurse will schedule this for you. It is important to have these done promptly , since your seeds have been ordered. Your doctor will instruct you on when to stop taking these medications before your surgery. A nurse from the Same Day Surgery Department will call you the afternoon before the day of your surgery. The nurse will go over your instructions and will tell you where to park and when and where to report.
Please plan to have a friend or family member come to the hospital with you on the day of your surgery, because you will not be able to drive home. When you arrive on the day of your surgery, an intravenous IV line will be started in your arm. This line will supply you with medications during the procedure. You will be given enemas to clean the rectum. You will be taken to the operating room and will be given medication to relax you.
Your urologist will then place a probe in your rectum to locate the prostate gland, so it can be viewed on a monitor. A catheter will be placed in your bladder to drain your urine.
Your radiation oncologist will place thin, hollow needles into the prostate gland, through the skin between the scrotum and the rectum. As the needles go through the prostate, they will be seen on the ultrasound monitor.
The radioactive seeds will be placed into your gland about one centimeter apart as the needles are taken out. The procedure will last about 45 to 90 minutes. After the procedure is complete, you will be taken to the recovery room where you will stay for about two hours.
You will then be transferred to the Same Day Surgery Unit. At this time, your friends and family may visit you. Your urologist will determine when to remove the urinary catheter. Sometimes, the catheter is left in place for two to three days. If this is the case, arrangements will be made to have it removed after you go home. Occasionally, a patient may need to be observed in the hospital until the next day. Your urologist will determine when you will be discharged from the hospital.
You will be given specific instructions about your implant. Keep these instructions so you can share them with your family members or with any doctors you see after your implant. The instructions will answer any questions you may have about radiation exposure to your family and friends after the implant. They are the same precautions that the radiation oncologist discussed with you.
There is little discomfort after the implant. Some patients do experience mild soreness when they sit. This soreness may last for one or two days after the implant. Sometimes, a patient will notice small spots of blood on his underwear after the procedure.
This comes from the spot where the needles were inserted and should stop within 24 hours. Applying mild pressure with a clean cloth will stop the spotting. You may notice a small amount of blood in your urine. This is normal and should stop within one to two days after the implant.
You should avoid heavy lifting or hard, physical activity for the first two days that you are home. After that time, you may return to your normal activity level. Side effects after the implant are generally mild and usually due to the radiation from the seeds in the prostate. These may include:. These symptoms may last for two to six months after the implant.
They will decrease little by little as the seeds lose their strength. Drinking plenty of fluids and avoiding caffeine may help the symptoms. If the symptoms are bothersome, your doctor will prescribe medication for you. Sometimes, a patient will experience a decrease in the force of the urinary stream. Your follow-up appointments are very important. The radiation oncology nurse will schedule you to see the doctor anywhere from six to 10 weeks after your implant.
Your follow-up appointment is dependent on the type of implant you have and whether you will receive external beam radiation treatments. After seeing the doctor, you will have x-rays and a CT scan taken of your pelvis. The x-rays and CT scan enable your doctor to see the exact position of your seeds and help determine the dose of radiation the prostate gland is receiving.
Follow-up appointments with your urologist and radiation oncologist will be made on a regular basis. A rectal exam and PSA will be done about every three to six months for the first year. If you were receiving hormone therapy, it will continue as scheduled for the length of time discussed before your implant.

This review of the literature on late rectal complications after prostate brachytherapy indicated that it is a highly effective treatment modality for patients with clinically localized prostate cancer but can cause chronic radiation proctitis.
It is interesting to note that the rates of late rectal morbidity appear to have declined over time, which may reflect improvements in implantation techniques and imaging. Rectal biopsy as part of the workup to evaluate rectal bleeding can lead to rectal fistula and the need for colostomy, a rare but major complication. The authors recommend 1 screening colonoscopy before brachytherapy for patients who have not had a screening colonoscopy within the preceding 3 years to rule out colorectal malignancies and, thus, facilitate conservative management should rectal bleeding occur; 2 lifestyle modifications during treatment to limit exposure of the rectum to radiation; and 3 conservative management for rectal bleeding that occurs within 2 years after brachytherapy.
Cancer The incidence of chronic radiation proctitis has increased over the past few years along with increased use of radiation therapy for the treatment of prostate cancer.
Nonconservative management of rectal bleeding—for example, with argon plasma coagulation APC or rectal biopsy—may result in fistula development and the need for a colostomy. The close proximity of the anterior rectal makes it difficult to limit radiation dose to this area without compromising prostate dose coverage.
Stranded seeds were used to maintain better seed spacing and alignment. SV indicates seminal vesicle; Gy, grays. In this review, we summarize the clinical manifestations, incidence, and treatment of late rectal complications after prostate brachytherapy.
Many patients who undergo prostate brachytherapy rely on their primary care physician, gastroenterologist, or colorectal surgeon for the management of late rectal complications after brachytherapy. The information provided in this article should help such clinicians provide patients with appropriate supportive care.
The effects of brachytherapy on the rectum can be classified as either acute or chronic. Acute radiation proctitis occurs shortly after implantation and usually resolves within 6 months, during which time the radioactive seeds deliver the majority of the radiation. Acute radiation proctitis is characterized by diarrhea, intermittent rectal bleeding, abdominal pain, mucous discharge, and occasionally constipation.
Pathologically, these changes usually are confined to the mucosa. In contrast to acute radiation proctitis, chronic radiation proctitis may take up to 2 years to develop and is not associated with the occurrence of acute proctitis. Rarely, rectal fistula or perforation can occur, necessitating surgical intervention. The histologic changes associated with late rectal injury often include submucosal involvement in addition to changes in the mucosa, such as telangiectasia.
The resulting decrease in bowel vascularity and ischemia of the rectal wall increase the risk of mucosal ulceration and submucosal fibrosis. A rare but major late rectal complication of prostate brachytherapy is the development of rectal fistula.
Rectal biopsy to evaluate rectal bleeding because of radiation proctitis appears to be an important factor in the development of rectal fistulas. This is an endoscopic image from a patient who had a rectal ulcer that was caused by chronic radiation proctitis.
Rectal outcomes have improved as implantation and planning techniques have been optimized and as experience with brachytherapy has grown. Until the late s, brachytherapy was performed with an open laparotomy approach.
The second generation was developed using a transperineal approach under ultrasound guidance, as described and pioneered in the US by Blasko et al. In early published experiences, late rectal morbidity rates were relatively high. The rationale was to decrease trauma to the prostate by using a smaller number of needles. The grade 1 late rectal complication rate in that experience was 4. However, not all novel approaches have led to improved rectal toxicity outcomes. It should be emphasized that the lack of uniform reporting criteria make it difficult to directly compare the rates of late rectal complications after brachytherapy.
In general, the rates of late rectal complications that could be managed with conservative therapy grade 2 ranged from 3. Anderson Cancer Center. Our finding that the majority of late rectal complications can be managed successfully with conservative therapy agree with those reported by other investigators in large series. Similarly, our finding that late rectal complications tend to occur within the first 2 years after implantation agrees with findings from other studies.
For example, Snyder et al and Kaye et al reported no episodes of chronic radiation proctitis after the third year postimplantation. There is a consensus in the prostate brachytherapy community that the probability of developing radiation proctitis increases with higher radiation dose to the rectal wall.
Thus, the goal of improving tumor control with higher doses must be balanced against the corresponding increased risk of complications. There is no consensus regarding the preferred treatment for rectal bleeding. The 3 general categories of commonly used interventions are medical, endoscopic, and surgical management Table 3. The majority of articles published on medical therapies for postradiation rectal bleeding are case reports or case series; only a few randomized trials have been performed.
Because of these limitations, the management of rectal bleeding largely remains empirical. The evidence suggests a better outcome but a higher risk of additional rectal complications with endoscopic techniques than with medical therapies.
For these reasons, medical therapies have fallen out of favor in recent years. Surgical interventions should be used only as a last resort, because they are associated with increased morbidity.
The following is a brief summary of therapies available for the treatment of postirradiation rectal bleeding that have been described in the literature. Studies by Sasai et al demonstrated clinical and endoscopic improvement in 3 patients who received oral sucralfate. It is anticipated that corticosteroids will help alleviate the symptoms of radiation proctitis.
The dependence of the colonic mucosa on SCFAs, butyrate in particular, increases toward the rectum. The use of hyperbaric oxygen has proved moderately successful in the treatment of rectal bleeding. A report by Warren et al indicated that 9 of 14 patients with chronic radiation proctitis experienced resolution of symptoms after therapy. Surgical treatment options include excision, diversion diverting stoma , and reconstruction.
Even with endoscopic approaches, however, there remains a risk of rectal ulceration or fistula, and this risk increases when larger radiation ulcers are treated. Thus, endoscopic therapy to control rectal bleeding should be done only by experienced gastroenterologists with particular awareness of postradiation rectal injury.
Early endoscopic approaches included delivery of topical formalin through a rigid scope and electrocauterization through the use of heater probes or bipolar probes. For many years, the use of heater probes or bipolar probes was the preferred endoscopic method for controlling postradiation rectal bleeding.
Heater probes are used to apply heat directly and reach temperatures up to degrees Fahrenheit, whereas bipolar probes use electricity to coagulate tissues and do not exceed degrees Fahrenheit.
Several different laser systems, including the Nd:YAG, argon, and KTP lasers, have been used for the treatment of postradiation rectal bleeding. Published data indicate that both the Nd:YAG laser and the argon laser are effective in the short term for treating rectal bleeding.
For the treatment of rectal bleeding after implantation, we recommend conservative management with oral and rectal steroids as well as rectal sucralfate. In some patients, persistent rectal bleeding may elicit concerns regarding colorectal malignancy, especially in those who have undergone previous pelvic irradiation. Baxter et al observed that the incidence of carcinoma increased significantly between Year 5 and Year 15 after prostate radiation therapy and that the incidence doubled from 0.
However, if there are concerns regarding carcinoma in patients who have a significant history of polyps, then a colonoscopy often is performed. Upon closer inspection of the data, the authors observed a strong association between rectal fistula formation and anterior rectal biopsy performed to evaluate rectal bleeding after implantation.
In none of the patients did rectal biopsy reveal information other than the presence of chronic radiation effects. We recommend avoiding rectal wall biopsy for the investigation of rectal bleeding after prostate brachytherapy unless cancer is strongly suspected. In conclusion, to minimize the risk of developing a nonhealing ulcer and subsequent fistula on the anterior rectal wall, we recommend 1 screening colonoscopy before brachytherapy for patients who have not had a screening colonoscopy within the preceding 3 years to rule out colorectal malignancies and, thus, facilitate conservative management should rectal bleeding occur; 2 lifestyle modifications, such as modifying diet to limit gas expansion of the rectum, limiting the duration of daily bicycle exercise, and, during treatment, limiting exposure of the rectum to radiation; and 3 conservative management for rectal bleeding and symptoms associated with chronic radiation proctitis that occurs within 2 years after brachytherapy.
