Outpatient therapy in metastatic breast cancer. A retrospective study of 90 patients treated in an oncology group practice.

BACKGROUND: Whenever possible, treatment of breast cancer should be performed in an outpatient setting, but only few data about patients being treated exclusively on an outpatient basis are available. PATIENTS AND METHODS: A retrospective analysis was performed in 90 unselected patients who were treated consecutively in our oncology group practice between 6/95 and 8/99. RESULTS: Median age at detection of metastases was 55 years (30-90) and performance status ranged from 0 to 2. 83 patients (92.2%) received chemotherapy, 7 (7.8%) received endocrine therapy only. CMF was used in 27.7%, anthracyclines in 71.1% and taxanes in 43.3%. 855 chemotherapy cycles were performed and the observed toxicity was mild. Reversible grade 3 and 4 hematotoxicity was seen after 27 cycles (3.2%). Neurotoxicity or mucositis grade 3 and 4 were seen in 6 patients (6.6%). Therapy-associated hospitalization occurred in 1 patient thrice due to febrile neutropenia. Complete remissions were seen in 5 patients (5.6%) during first-line therapy. Median survival of the whole cohort until the end of the follow-up period (2/03) was 28 months (2-259). Overall survival after 1, 2, 3 and 5 years was 83, 56, 33 and 18% respectively. 50% could die at home. CONCLUSIONS: Treatment of metastatic breast cancer can be performed with minimal toxicity and a high patient acceptance in the outpatient setting. Overall survival and median survival are comparable to historical results achieved in specialized academic hospitals. Hospitalization could be avoided in the majority of patients and half of them could die at home.

Palliative treatment of advanced pancreatic carcinoma in community-based oncology group practices.

This study was aimed at evaluating the feasibility, effectiveness, and toxicity of palliative chemotherapy/supportive care in patients with advanced pancreatic cancer being treated on an outpatient basis. A retrospective analysis was performed on 127 consecutive, unselected patients with advanced pancreatic cancer in four community-based oncology group practices. Median age was 63 years and WHO performance status ranged from 0 to 3. Forty-three patients (34%) had locally advanced disease, and 84 patients (66%) had distant metastases; 94 patients (74%) received cytotoxic treatment during the course of their disease, and 33 (26%) received best supportive care only. First-line treatment consisted of gemcitabine (1,000 mg/m2 on days 1, 8, and 15 of a 28-day cycle) in 81 patients (86%), 5-fluorouracil (5-FU) in 8 patients (9%), radiochemotherapy in 4 patients (4%), and radiation therapy only in 1 patient (1%). A total of 1,501 gemcitabine treatments were given during the study period. Toxicity was moderate. Four patients (3%) required hospitalization for treatment-related side effects, and 111 patients (88%) died during the observation period. Symptom control, as measured by reduction of pain medication, was seen in 25% of patients receiving gemcitabine, whereas no reduction in pain medication was seen in the best supportive care group. The median survival of patients receiving cytotoxic treatment (mainly gemcitabine) was 42 weeks, and the median survival of patients receiving best supportive care was 21 weeks. The overall survival rate at 6, 12, 24, and 36 months was 65%, 32%, 14%, and 7%, respectively. Based on these outcomes, it appears that patients with locally advanced and metastatic pancreatic cancer benefit from adequate palliative treatment, including cytotoxic chemotherapy with gemcitabine, and this can be accomplished on an outpatient basis.

Successful long-term treatment of systemic lupus erythematosus with rituximab maintenance therapy.

Systemic lupus erythematosus (SLE) is a chronic, inflammatory autoimmune disease that may involve multiple organ systems. Treatment consists of immunosuppression, cytotoxic treatment, plasmapheresis and immunoglobuline therapy. Treatment of patients refractory to standard treatment approaches is difficult and results are poor. We describe a 39-year old patient with SLE suffering from grand mal epilepsy due to cerebral vasculopathy with positive lupus anticoagulant, who was refractory to standard treatment modalities. The patient was treated with the anti-CD20 monoclonal antibody rituximab (375 mg/m2 x 4, repeated at weekly intervals). Rituximab applications were delivered in October 2000, March 2001 and October 2001. Since March 2002 she has received maintenance therapy with rituximab 375 mg/m2 every three months. A second female with refractory SLE was treated successfully in April 2002 and receives maintenance therapy every three months. Both patients responded well to rituximab therapy. The first patient showed a major improvement of her clinical condition, and 30 months after the beginning of the rituximab therapy she is free of any symptoms. Inflammation parameters, ANA and lupus anticoagulant declined significantly after the treatment. The clinical condition of the second patient improved dramatically, all inflammation parameters normalized and her circulating immunocomplexes disappeared. In conclusion, rituximab maintenance treatment may be a new effective therapy in SLE.
