T1a: The tumor is discovered accidentally during a surgical procedure used to treat benign prostatic hyperplasia BPH , which is the abnormal growth of benign prostate cells. Cancer is only found in 5 percent or less of the tissue removed. T1b: The tumor is found accidentally during BPH surgery. Cancer cells are detected in more than 5 percent of the tissue removed. T1c: The tumor is found during a needle biopsy that was performed because of an elevated PSA level. T2: The tumor appears to be confined to the prostate.
Due to the size of the tumor, the doctor can feel it during the DRE. The cancer may also be seen with imaging. Although this group has traditionally been characterized as having early-stage disease and the best prognosis, on review of these patients, we instead found a very heterogeneous group with a wide spectrum of outcomes that depend on both patient Gleason grade and pretreatment PSA and treatment dose factors.
Methods and materials: A retrospective analysis was performed on patients with stage T1c prostate adenocarcinoma who were referred for radiation therapy from All patients underwent central review of pathology. Clinical local recurrence, nodal recurrence, distant metastases, and PSA relapse were recorded.
Additionally, the high likelihood that postoperative radiotherapy will be required potentially exposes patients to toxicities of both surgery and radiotherapy. A significant number of patients will still require postoperative radiation following radical prostatectomy because they are at an increased risk of cancer recurrence. Clinical studies have demonstrated that adjuvant radiation following radical prostatectomy may prolong the time until PSA recurrence, delay the use of hormonal therapy, and improve overall survival for certain patients.
Adjuvant radiation therapy is typically offered to high-risk patients following surgical prostatectomy. This includes individuals defined as high-risk and those found to have cancer involving the margins of the surgical specimen, seminal vesicle invasion, positive surgical margins, or extraprostatic extension following prostatectomy and individuals where the PSA remains persistently elevated. The ideal time to deliver radiation therapy following radical prostatectomy is the subject of some debate.
Radiation can be administered immediately after prostatectomy to high-risk individuals or in some cases delayed until there is evidence of PSA recurrence. The understanding of how best to use radiation following prostatectomy continues to evolve and patients should discuss the role and timing of radiation with their treating physician.
In the management of high-risk prostate cancer ADT has been used before neoadjuvant , during concurrent , and after adjuvant local therapy. Clinical studies have demonstrated that ADT combined with EBRT delays cancer progression and improves survival in men with high-risk prostate cancer.
The use of hormone therapy to shrink the prostate cancer prior to radical prostatectomy or radiation therapy can be used to 1 to reduce the prostate size prior to prostate brachytherapy and 2 to sensitize malignant cells to radiation during EBRT. This volume reduction may reduce the number of prostate cancer cells and diminish the volume irradiated decreasing the side effects.
The understanding of how best to use ADT in men with high-risk prostate cancer continues to evolve and patients should discuss the role of ADT carefully with their treating physician. The progress that has been made in the treatment of prostate cancer has resulted from development of better treatments that were evaluated in clinical studies.
Future progress in the treatment of stage I prostate cancer will result from continued participation in appropriate clinical trials. Currently, there are several areas of active exploration aimed at improving the treatment of localized prostate cancer. Timing of Radiation: Although the use of radiation following prostatectomy improves outcomes in high-risk patients, some patients do not benefit and are exposed to its side effects unnecessarily.
Clinical trials are ongoing to determine which patients benefit from radiation and whether radiation is best used immediately following prostatectomy or can be delayed in selected patients. Some radiation oncology centers use different types of radiation that require special machines to generate. These different types of radiation, such as protons or neutrons, appear to kill more cancer cells with the same dose. Combining protons or neutrons with conventional x-rays is one method of radiation therapy being evaluated in clinical trials.
Treatment also depends on:. You might not have treatment straight away. Sometimes your doctor monitors your cancer and starts treatment if the cancer begins to grow. Depending on your situation, they may call this:.
The Gleason score and Grade Group gives your doctor an idea of how the cancer might behave and what treatment you need. Your treatment depends on a number of factors including how big the cancer is, whether it has spread anywhere else in your body and how well you are. Survival depends on many factors including the type of your prostate cancer and how well you are overall. About Cancer generously supported by Dangoor Education since
