High-dose chemotherapy and autologous stem cell rescue for metastatic breast cancer: superior survival for tandem compared with single transplants.

During 1990-1999, we treated 60 patients with breast cancer who had distant metastases with high-dose chemotherapy and autologous stem cell rescue (HDC) after they had responded to induction chemotherapy. HDC regimens were MiTepa (60 mg/m2 mitoxantrone by continuous intravenous infusion over 3 days plus 300 mg/m2 thiotepa intravenously over 2 hours daily x 3 days) and ICE (12 g/m2 ifosfamide, 1800 mg/m2 carboplatin, 2 g/m2 etoposide; all 3 by continuous intravenous over 4 days). At a median follow up >8 years, the median failure-free survival (FFS) was 13.9 months, median overall survival (OS) 29.1 months, 5-year FFS 12%s and 5-year OS 25%. Thirty-three patients underwent tandem (T) transplants; 27 underwent a single (S) HDC. Median ages for these 2 groups were 45 and 48 years; bone and liver metastases were more prevalent in the T cohort, whereas lung metastases were more prevalent in the S cohort. At a median follow up of 6.5 years for the S group and >9 years for the T group, there were 52 deaths. FFS was better for T: median 15.7 versus 7.7 months (p2 = 0.010) as was OS: median 32.7 versus 17.7 months, 2-year survival 68% versus 41%, and 5-year survival 32% versus 15% (p2 = 0.010). As a group, patients with distant metastatic breast cancer who underwent tandem transplants had a better posttransplant survival than patients who underwent a single HDC.

Cancer patient survival improvement is correlated with the opening of a community cancer center: comparisons with intramural and extramural benchmarks.

PURPOSE: We sought to determine whether survival of patients managed at a large community hospital improved after an affiliated facility opened and its associated programs were initiated. METHODS: Survival data for patients with invasive cancer was obtained from the Hoag Hospital tumor registry for the successive periods 1986-1991 and for 1992-1999 for historical intramural comparisons; national Surveillance, Epidemiology, and End Results (SEER) program data for the same periods were used for contemporary and historical extramural comparisons. RESULTS: We observed survival improved significantly during 1992-1999 compared with 1986-1991 for all patients with invasive cancers (P < .0001), and specifically for cancers of the breast (P = .026), lung (P = .012), prostate (P < .0001), stomach (P = .006), pancreas (P = .0001), and oral cavity (P = .024), with strong trends for improved survival for leukemia (P = .051) and rectal cancer (P = .063). Relative 5-year survival rates increased from 63% during 1986-1991 to 71% during 1992-1999, and were higher for 22 of 24 tumor types during the more recent period (P < .0001). Compared with SEER data, Hoag relative survival for all patients with invasive cancer was 63% versus 58% during 1986-1991, and 71% versus 64% during 1992-1999. Survival for Hoag patients was better than SEER rates for only 50% of malignancies (12 of 24) during 1986-1991 compared with 87% (21 of 24) during 1992-1999 (P = .013). In the most common tumor types, there were substantial improvements in survival for patients with regional disease at diagnosis. Improved survival was associated with earlier diagnosis and increased use of systemic treatment and combined modality therapy. CONCLUSION: Patients with invasive cancer who were treated at an integrated community cancer center had better survival compared with historical survival and patients from the SEER registry. The findings are consistent with the hypothesis that the accelerated dissemination of new information resulted in earlier adoption of improved screening, diagnostic, and multidisciplinary treatment approaches, leading to higher survival rates.

Intracavitary placement of autologous lymphokine-activated killer (LAK) cells after resection of recurrent glioblastoma.

This study was performed to obtain safety and survival data for patients with histologically confirmed recurrent glioblastoma multiforme (GBM) who received intralesional lymphokine-activated killer (LAK) cells following surgery. LAK cells were generated by incubating peripheral blood mononuclear cells with interleukin-2 for 3 to 5 days in vitro. Forty patients with pathologic confirmation of GBM at surgery had placement of autologous LAK cells into the tumor cavity. The 23 men and 17 women had a median age of 48 years (range 21-76). The median interval from the original diagnosis of glioma to LAK treatment was 10.9 months. Patients received an average of 2.0 +/- 1.0 x 10(9) LAK cells, with viability of 91 +/- 6.8%. Treatment was well tolerated; there was one death within 60 days. At a median follow-up of 2.3 years, median survival post-LAK was 9.0 months; 1-year survival was 34%. Gender, age, location of tumor, LAK cell lytic activity, number of cells implanted, and inclusion of interleukin-2 at cell instillation were not correlated with outcome. Median survival from the date of original diagnosis for 31 patients who had GBM at initial diagnosis was 17.5 months versus 13.6 months for a control group of 41 contemporary GBM patients (p2 = 0.012). This treatment is safe and feasible. The median survival rates are higher than reported in most published series of patients who underwent reoperation for recurrent GBM. A randomized trial would be needed to establish therapeutic benefit.
