Long-term results of combined ESWL and ERCP treatment of chronic calcific pancreatitis.

OBJECTIVE: Extracorporeal shock wave lithotripsy (ESWL) combined with endotherapy (ET) is the standard treatment for pancreatic duct stones (PDS) in chronic pancreatitis (CP). Our aim was to report the short- and long-term results of ESWL and ET. MATERIAL AND METHODS: Consecutively treated 83 patients with symptomatic PDS using ESWL and ET. Success was defined (i) technically: PDS fragmentation and clearance obtained and (ii) clinically: improvement/resolution of pain. To get information on quality of life, we conducted a phone survey whereby we contacted 64 (89%) patients. The long-term results are presented in those patients with ≥2 years follow-up. RESULTS: Treated PDS with median size of 10 (5-25) mm were located in the head, body, or the tail of the pancreas in 78, 4, and 1 patients, respectively. The primary results were that technical success was achieved in 69 patients (83%) and clinical success in 66 patients (80%). Fourteen patients had technical failure, but eight of them became free of pain. Thus, clinical success can be considered to have been achieved in 74 of 83 patients (89%). In patients with persistent pseudocyst (PC) at the time of ESWL (n = 19), the PC disappeared in a year in 14 patients (74%). The long-term results were obtained from 61 (73%) ESWL- and ET-treated patients. The median follow-up for them was 53 months (range: 24-124) and 57 patients (93%) became pain-free or had less pain. CONCLUSIONS: For patients with CP and PDS ESWL combined with ET is an effective and safe treatment giving favorable long-term results.

[Treatment of localized prostate cancer having a good prognosis may cause more harm than benefit]. / Hyväennusteisen paikallisen eturauhassyövän hoidosta voi olla enemmän haittaa kuin hyötyä.

The extensive use of prostate-specific antigen determination has considerably increased the incidence of prostate cancer. Due to earlier diagnosis, localized small cancers are found that in all probability are clinically insignificant. Overdiagnosis leads to overtreatment and to significant adverse effects. Localized prostate cancers of elderly patients having multiple diseases have often merely been monitored without therapy. Active monitoring should now be adventured also for younger men, whose tumor fulfils the criteria of minimal cancer.

Prognostic grouping of metastatic prostate cancer using conventional pretreatment prognostic factors.

OBJECTIVE: To develop three prognostic groups for disease specific mortality based on the binary classified pretreatment variables age, haemoglobin concentration (Hb), erythrocyte sedimentation rate (ESR), alkaline phosphatase (ALP), prostate-specific antigen (PSA), plasma testosterone and estradiol level in hormonally treated patients with metastatic prostate cancer (PCa). MATERIAL AND METHODS: The present study comprised 200 Finnprostate 6 study patients, but data on all variables were not known for every patient. The patients were divided into three prognostic risk groups (Rgs) using the prognostically best set of pretreatment variables. The best set was found by backward stepwise selection and the effect of every excluded variable on the binary classification cut-off points of the remaining variables was checked and corrected when needed. RESULTS: The best group of variables was ALP, PSA, ESR and age. All data were known in 142 patients. Patients were given one risk point each for ALP > 180 U/l (normal value 60-275 U/l), PSA > 35 microg/l, ESR > 80 mm/h and age < 60 years. Three risk groups were formed: Rg-a (0-1 risk points), Rg-b (2 risk points) and Rg-c (3-4 risk points). The risk of death from PCa increased statistically significantly with advancing prognostic group. CONCLUSION: Patients with metastatic PCa can be divided into three statistically significantly different prognostic risk groups for PCa-specific mortality by using the binary classified pretreatment variables ALP, PSA, ESR and age.

A high pretreatment plasma oestradiol level is associated with a low risk of acute myocardial infarction in parenteral oestrogen therapy for locally advanced prostate cancer.

OBJECTIVE: To evaluate the relationship of pretreatment plasma oestradiol (ppE2) and testosterone (ppT) level to acute myocardial infarction (AMI) in patients with locally advanced prostate cancer primarily treated with parenteral polyoestradiol phosphate (PEP) or orchidectomy, considering the effect of age, performance status, pretreatment diseases and medication, and tumour stage and grade. PATIENTS AND METHODS: The present Finnprostate 6 study comprised 234 patients randomized to oestradiol or intramuscularly administered PEP (240 mg/month) therapy. Each patient was followed until the end of the primary therapy (up to 10 years) or until the first AMI (lethal or not). RESULTS: The risk of AMI, when the PEP and orchidectomy groups were analysed together, was lower in patients with a high ppE2 level, and this risk was independent of the ppT level, pretreatment diseases, medication, age, performance status, disease stage or grade. In the PEP therapy group the risk of AMI was statistically significantly lower in patients with a high ppE2 level (>or=93 pmol/L) than in those with a low ppE2 level (<93 pmol/L; risk ratio 0.28, 95% confidence interval 0.10-0.84, P = 0.022). There was no such difference in the orchidectomy group. The ppT level had no association with the risk of AMI. CONCLUSIONS: A high ppE2 level is associated with a low risk of AMI in patients with locally advanced prostate cancer treated with PEP; there was no such association for ppT level. In the orchidectomy group the ppE2 or ppT level was not statistically significantly associated with the risk of AMI.

Ten-year survival and cardiovascular mortality in patients with advanced prostate cancer primarily treated by intramuscular polyestradiol phosphate or orchiectomy.

BACKGROUND: The aim of the study was to evaluate overall and prostate cancer (PCa) specific survival with special attention to cardiovascular (CV) mortality in patients primarily treated by parenteral polyestradiol phosphate (PEP) 240 mg/month or with orchiectomy (OE), taking into account the effect of pretreatment diseases and medication, and later PCa therapies. METHODS: The present Finnprostate 6 study (10-year follow-up) consisted of 244 patients with locally advanced PCa (T3-4 M0) and 200 patients with metastatic PCa (T1-4 M1). Patients were randomized to OE or PEP therapy. The T3-4 M0 and T1-4 M1 patients were analyzed separately. RESULTS: There was no difference in overall or PCa specific survival between the primary therapy groups in T3-4 M0 or T1-4 M1 patients. In the T3-4 M0 patients the primary treatment (PEP vs. OE) was statistically significantly associated with a risk of CV deaths (P = 0.001). Such an association was not found in the T1-4 M1 patients. CONCLUSIONS: The primary PEP and OE therapies are equal in terms of overall and PCa specific survival in patients with T3-4 M0 or T1-4 M1 disease. In T3-4 M0 patients PEP increases the risk of CV deaths compared to OE but not in T1-4 M1 patients.

Cardiovascular complications in patients with advanced prostatic cancer treated by means of orchiectomy or polyestradiol phosphate.

OBJECTIVE: To evaluate the cardiovascular (CV) complications associated with orchiectomy (OE) and parenteral polyestradiol phosphate (PEP) therapy (240 mg/month), taking into account the effect of pretreatment diseases and pretreatment medication. MATERIAL AND METHODS: A total of 244 T3-4 M0 patients and 200 T1-4 M1 patients were randomized to either OE or PEP therapy. The two groups of patients were analyzed separately. The follow-up period was 36 months. The effect of pretreatment vascular and other diseases and pretreatment medication which may be associated with a risk of CV complications was evaluated. RESULTS: In the T3-4 M0 patients, the treatment (PEP versus OE) and the presence of pretreatment vascular diseases were statistically significantly associated with a risk of CV complications (p=0.01 and 0.003, respectively). In the T1-4 M1 patients, such an association was not found. No association was observed between pretreatment medication and CV complications. There was no difference in progression-free time between the therapy groups in either the T3-4 M0 or T1-4 M1 patients. CONCLUSION: In patients with locally advanced prostatic cancer, PEP therapy is associated with a statistically significantly higher risk of CV complications compared to OE.
