Twice-daily pain monitoring as standard clinical practice for inpatients at a medical oncology unit: a descriptive study.

BACKGROUND: Very limited experiences have explored the use of pain intensity monitoring in everyday clinical practice at a medical oncology inpatient unit. METHODS: The program 'Pain-Free Hospital,' including a training course for nurses and the recording every 12 h of a visual analog scale (VAS) rating in all the patients admitted to the inpatients' ward independently of their disease stage, was activated in 2002. An audit on the clinical charts of patients admitted for the first time in the first semester of 2003 was carried out in order to ascertain the applicability of the procedure and its congruence with patients' clinical status. RESULTS: The VAS rating was reported in 211 out of 223 (94.6%) clinical charts. At entry, 60 out of 211 (28.4%) patients presented VAS>or=1, 21 (35%) of whom were not taking any analgesics. The mean VAS score>or=1 was 3.4. No statistically significant difference emerged in the distribution of VAS rating as regards disease extension, presence or absence of bone metastases and performance status. CONCLUSIONS: The systematic monitoring of VAS by nurses at a medical oncology inpatients' ward is feasible with a good patient compliance. The reliability of the procedure in terms of guiding the analgesic treatment has yet to be demonstrated.

A new regimen of cisplatin, epirubicin and methotrexate (PEM-3) as primary chemotherapy for locally advanced bladder cancer.

In this phase II study, 41 patients with locally advanced urothelial bladder cancer (T2-4, N0, M0) were treated with primary chemotherapy (cisplatin, epirubicin, methotrexate: PEM-3). All the patients were assessable for response and toxicity. Clinical monitoring was performed with computerized tomography and cystoscopy. Nineteen clinical complete remissions (46%) and 10 partial remissions (24.5%) were obtained (CR + PR, 70.5%; 95% confidence interval, 57%-85%). Ten patients were considered to have clinically stable disease (24.5%), and 2 patients progressed (5%). Surgery after chemotherapy was performed in 22 cases: in 6 patients (27%) a pathologic complete response was achieved. The pathologic stage was lower than the initial clinical stage in 13 patients (59%). After a median follow-up of 3 years (range, 1-4), the median time to progression was 104 weeks. At this writing, 20 patients, 12 of which were submitted to surgery and 8 were not operated, are disease-free. The 3-year survival rate is 52%. No one had to interrupt the treatment because of toxicity. In conclusion, the PEM-3 regimen is a very active and well-tolerated regimen in locally advanced bladder cancer.

Weekly regimen of 5-FU vs 5-FU + intermediate dose folinic acid in the treatment of advanced colorectal cancer.

Sixty-four patients with advanced colorectal cancer were randomized to receive 5-fluorouracil (5-FU) at the dose of 600 mg/sm weekly or the same regimen of 5-FU administered halfway through a 1 hour i.v. infusion of folinic acid (FA) at the dose of 200 mg/sm. A partial remission (PR) was obtained in 1/30 patients (3%) treated with 5-FU and in 9/34 patients (26%) treated with 5-FU + FA (P = 0.028). The objective response was accompanied by an improvement in subjective status and general conditions. The median duration of PR in 5-FU + FA arm was 10 months (range: 6-17). The median time to progression was 5 and 6 months in patients treated with 5FU and 5FU + FA, respectively (not a statistically significant difference). There were no cases of grade 4 toxicity. A higher, but not statistically significant, incidence and intensity of diarrhoea was observed in the 5-FU + FA arm. However, 14 patients on 5-FU + FA as opposed to 3 on 5-FU had to stop the treatment temporarily because of side-effects (P = 0.011). Median survival was higher with 5-FU + FA treatment (10 vs 7 months), but the difference is not statistically significant. This study confirms that the addition of an intermediate dose of FA enhances the cytotoxicity of 5-FU. Although its clinical advantage was limited, this weekly 5-FU + FA regimen appears useful in the treatment of advanced colo-rectal cancer on a outpatient basis.

A randomized clinical trial with a weekly regimen of 5-fluorouracil with or without folinic acid in advanced gastrointestinal adenocarcinomas: a preliminary report.

Eighty patients with advanced gastrointestinal tumors (64% with colorectal cancer) entered a phase III prospective randomized study with 5-fluorouracil (5-FU) vs 5-FU + folinic acid (FA) The treatment included 5-FU, 600 mg/m2/week for 6 weeks, given as i.v. bolus alone (arm A), or administered by rapid injection half-way through a one-hour infusion of FA, 200 mg/m2/week for 6 weeks (arm B). Partial remission (PR) was achieved in 1 out of 30 (3%) evaluable patients for 6 months in arm A, and in 10 out of 34 (29%) patients in arm B, with a median duration of 8 months (range 6-17) (comparison of the response rate: P = 0.005). In patients with colorectal cancer the response rate was 5% and 27% in arm A and in arm B respectively (P = 0.06). Two patients, who were resistant to 5-FU alone, achieved PR after treatment with 5-FU + FA. Diarrhea was observed in 14/42 patients (33%) in arm B (grade 1-2 in 10 and grade 3 in 4) and in 2/38 patients (5%) in arm A (P = 0.005). Other side effects such as nausea/vomiting, myelosuppression and stomatitis were infrequent and of mild intensity in both arms. No statistical difference in survival was detected when comparing the two groups (estimated median survival 8 months and 11 months for arm A and arm B respectively). These results seem to indicate that the weekly regimen of 5-FU + FA has a superior response rate compared to 5-FU alone, and that it is well tolerated. However, the advantage is not reflected in overall survival.

The authors report data concerning their study on the incidence of pain in advanced neoplastic patients and on the natural history of this symptom. They also report their experience in the treatment of solid tumours with non steroidal antiinflammatory drugs (Zomepirac, acetylsalicylic acid, Diflunisal, Ketoprofen) with a synthetic progestin (Medroxyprogesterone Acetate employed by authors at high or at very high doses for the first time) and with morphine hydrochloride used by oral, rectal, sublingual and nasal route. The authors also indicate the correct strategy of employing these drugs and criteria of evaluating their effectiveness.

Experimental study on the anabolic and androgenic/antiandrogenic activity of different dose levels of medroxyprogesterone acetate (MAP) in rats.

The authors treated three groups of rats with medroxyprogesterone acetate (MAP) at different dosages (0, 2.5, 5, 10, 20, 40, 80 mg/kg) i.p. and orally for 7 days to evaluate its anabolic and its androgenic/antiandrogenic effect. 70 rats had been previously castrated and 35 were intact. The anabolic effect is evident in all groups of animals which were treated. The androgenic action predominates in castrated animals, while the antiandrogenic action predominates in intact animals. The above-mentioned actions are more marked when very high doses are used. After suggesting the possible mechanism of action of MAP, the authors point out that the anabolic effect confirms what has already been reported in clinical oncology after treatment with very high doses of MAP (1,000-2,000 mg orally or i.m. for 30 days) in different types of tumors (breast, kidney, prostate).
