Feasibility of quantitative pain assessment in outpatient oncology practice.

PURPOSE: Although physicians view failure to assess pain systematically as the most important barrier to outpatient cancer pain management, little is known about pain assessment in this setting. We sought to determine whether pain is routinely assessed and whether routine quantitative pain assessment is feasible in a busy outpatient oncology practice. PATIENTS AND METHODS: We conducted a pre- and postintervention chart review of 520 randomly selected medical and radiation oncology patient visits at a community hospital-based private outpatient practice. The intervention consisted of training health assistants (HAs) to measure and document patient pain scores by using a visual analog scale. The main outcome measures included HA documentation of patient pain scores, quantitative and qualitative mention of pain in the physician note, and analgesic treatment before and after the intervention. RESULTS: After the intervention, HA documentation of pain scores increased from 1% to 75.6% (P < .0001). Physician documentation increased from 0% to 4.8% for quantitative documentation (P < .01), and from 60.0% to 68.3% for qualitative documentation (not significant). Of all the patients, 23.1% reported significant pain. Subgroups with greater pain included patients actively receiving radiation treatments and patients with lung cancer. Of patients with significant pain, 28.2% had no mention of pain in the physician note and 47.9% had no documented analgesic treatment. CONCLUSION: Quantitative pain assessment was virtually absent before our intervention but easily implemented and sustained in a busy outpatient oncology practice. Pain score collection identified a high prevalence of pain, patient subgroups at risk for pain, and a significant proportion of patients with pain that was neither evaluated nor treated by their oncologists.

Metastatic endometrial adenocarcinoma to the skin of a toe.

A 55-year-old woman had a history of prolonged vaginal bleeding. Dilatation and curettage confirmed poorly differentiated endometrial adenocarcinoma. After hysterectomy, salpingo-oophorectomy, and 5,040 cGy of postoperative irradiation, lung metastases developed, which temporarily responded to chemotherapy that included adriamycin and cisplatin. Metastatic lesions developed later in the left acetabulum and the hallux. The latter, clinically reminiscent of pyogenic granuloma, affected only skin. The poorly differentiated toe metastasis duplicated areas of the primary endometrial adenocarcinoma and was immunohistochemically similar to it. While appearing quite rarely, and generally late in the disease, pedal skin lesions may represent metastases from known or occult visceral cancers.

Sixteen-week dose-intense chemotherapy in the adjuvant treatment of breast cancer.

Fifty-three women with breast cancer were treated with a new 16-week dose-intense, chemotherapy regimen. Patients with operable breast cancer with 10 or more histologically positive axillary nodes were treated with this five-drug regimen that incorporated the concepts of weekly chemotherapy, sequential administration of antimetabolites, and continuous infusion of fluorouracil (5-FU). The chemotherapy regimen consisted of eight cycles (each of 2 wk duration) of 100 mg of cyclophosphamide/m2 orally on days 1-7, 40 mg of doxorubicin/m2 intravenous (IV) on day 1, 100 mg of methotrexate/m2 IV on day 1 with 10 mg of leucovorin rescue/m2 every 6 hours for six oral doses on day 2, 1 mg of vincristine IV on day 1, and 600 mg of 5-FU/m2 IV at hour 20 over 2 hours. A continuous infusion of 300 mg of 5-FU/m2 per day was given IV on days 8-9 of each 2-week cycle. The doses and schedule of drug administration were designed to minimize dosage reduction and treatment delay. At a median follow-up of 17 months, there have been eight relapses in the 53 patients. The actuarial 3-year disease-free survival is 80% (95% confidence interval, 62% to 90%). The major side effects were attributable to myelosuppression. Absolute neutrophil counts less than 250/microL were noted in 12 (23%) patients; seven patients (13%) required hospitalization for management of neutropenic fever. No treatment-related deaths occurred. Ninety-four percent of the planned doses were administered, and only 5% of the courses were delayed because of toxic reactions. The encouraging therapeutic data, manageable side effects, and our ability to deliver over 90% of the planned doses provide the rationale for a phase III comparison of this new dose-intense regimen and standard chemotherapy in patients with operable disease and positive axillary nodes.

Intensive alternating chemotherapy regimen in small cell carcinoma of the lung.

Fifty-five patients with small cell carcinoma of the lung (SCCL) were treated with alternating courses of CAV (cyclophosphamide, doxorubicin, and vincristine) and VHM (etoposide, hexamethylmelamine, and methotrexate) at 21-day intervals. One regimen contained high-dose cyclophosphamide (2400 mg/m2 iv), while the second contained an increased dose of etoposide (250 mg/m2 iv on Days 1-3). Patients achieving a complete response (CR) received a minimum of six cycles of therapy or two cycles beyond the achievement of CR. These patients as well as those with partial response with disease limited to the lung then received radiotherapy to the lung primary (5100 rads in 300-rad fractions) as well as prophylactic cranial radiotherapy (3000 rads in 300-rad fractions). All therapy was subsequently stopped until relapse. There were no deaths during the aplastic periods induced by the intensive chemotherapy. CR was achieved in 57% of the patients and partial response was achieved in 38%. The actuarial median survival for the 27 patients with extensive disease was 13.5 months and for the 28 patients with limited disease was 13 months. Survival at this point appears comparable to less intensive regimens in which maintenance therapy was given. We conclude that prolonged intensive induction chemotherapy in SCCL is well-tolerated. Studies are needed to examine in a randomized trial the role of alternating combinations and maintenance therapy in SCCL.

Adriamycin and 1-(2-chlorethyl)-3-cyclohexyl-1-nitrosourea (CCNU) in the treatment of metastatic breast cancer.

Adriamycin every three weeks and CCNU every six weeks were given to thirty patients with metastatic breast carcinoma. Most patients had received prior chemotherapy. The overall response rate was 40%, with three patients obtaining complete remission. Survival was significantly prolonged in responders versus nonresponders. Three patients developed CNS metastasis while on treatment. Prior chemotherapy was a major factor in determining response rate; all patients without prior chemotherapy responded. The combination appears to be inferior to adriamycin alone in patients who have received prior chemotherapy.
