Prostate cancer is a common type of cancer affecting male patients. Most prostate cancers are slow-growing; symptoms and signs include difficulty urinating or impaired sexual ability. Heredity and diet are implicated as possible factors in prostate cancer. It can be treated with hormone therapy and chemotherapy.

One of AME's prostate cancer expert witnesses has written an exclusive medical malpractice article that we have provided, for your interest, below.

Prostate Cancer- delay in diagnosis, failed follow-up strategy

Attorneys are often consulted by patients who feel that they have not been properly followed after cancer had been treated and that a recurrence could have been diagnosed earlier but was missed. Different cancers have different follow-up recommendations. For prostate cancer,

PSA is the mainstay of the follow-up strategy.

One consequence of the routine adoption of PSA monitoring after treatment of early stage prostate cancer is the identification of men with a PSA-only recurrence. In this situation, increases in serum PSA over the pretreatment baseline are often not accompanied by signs or symptoms of progressive disease. When PSA rises, the physician is often faced with a quandary. The longer one waits to perform an imaging study, the greater the chance that a recurrence can be confirmed and treatment started. On the other hand, imaging too early in the course of PSA rising, might result in a negative study, frustrated patient, avoidable expense and the need to repeat imaging at a future time. If the rise in the PSA is slow and occurs after a prolonged period, the site of relapse is generally at the site of the original tumor. Since a significant number of these men are relatively young and otherwise healthy and can still be cured, intense interest has been focused upon their treatment, with particular attention to survival, and the impact of therapy on quality of life.

Treatment options for men with a PSA-only recurrence after radical prostatectomy include external beam radiation therapy (RT) to the prostatic bed with or without treatment of the pelvic lymph nodes (salvage RT), androgen deprivation therapy (ADT), a combination of salvage RT plus ADT, or observation. Most of the available data regarding these approaches has come from observational series. Long-term results of randomized clinical trials will be required to define the optimal approach.

After prostatectomy, PSA should be 0.0 or close to zero. Rising PSA suggests recurrence even if the absolute PSA values is low. When this fact is not appreciated, a recurrence can be missed because the PSA, although higher, is still within the “normal” range. There is some controversy on whether any PSA rise warrants re-treatment or whether the PSA Velocity (rate of PSA rise over time) should be used to predict when to intervene.
