High dose cytarabine, mitoxantrone and l-asparaginase (HAMA) salvage for relapsed or refractory acute myeloid leukemia (AML) in the elderly.

Acute myeloid leukemia (AML) is an aggressive malignancy that affects older patients. The role of salvage therapy in the elderly is controversial and there is little data on efficacy. Outcomes for 94 relapsed or refractory AML patients who received salvage HAMA therapy were analyzed. Of the 94 patients 66 were ≥60, including 26 patients ≥70, and 28 were <60 years old. Early mortality (30-day) was 14% (4%<60, 18%≥60 years old). Overall, 27% of patients died during hospitalization or were discharged to hospice (11%<60, 33%≥60 years old). CR/CRi was achieved in 41% of patients (61%<60, 33%≥60 years old). Median survival was 6.1 months (15.7<60, 5.2≥60). Patients ≥60 who achieved a CR/CRi had a median survival of 11.7 months. At 12 months 56% of patients <60 were alive versus 24% of patients ≥60. At 24 months these numbers fell to 40% and 2% respectively. In those <60 years old, 50% went on to allogeneic hematopoietic stem cell transplant (HSCT) whereas 14% of patients in the ≥60 cohort did so. In conclusion, HAMA salvage therapy results in a 33% response rate in patients ≥60 years old with acceptable toxicity.

Radiation therapy for management of t1-t2 glottic cancer at a private practice.

PURPOSE: The purpose of this study was to retrospectively analyze patients with T1-T2N0 squamous cell carcinomas of the glottic larynx treated at a private institution, to review the pertinent literature, and to compare our outcomes to those of academic institutions. METHODS AND MATERIALS: A total of 118 patients were treated with radiation therapy between May 1987 and August 2006 at a private institution and followed up for ≥2 years. Three patients were lost to follow-up between 18 and 19 months. RESULTS: The 5-year local control rates were: T1a, 91%; T1b, 95%; T2a, 96%; and T2b, 100%. The 5-year ultimate local control rates after irradiation and including patients who were successfully salvaged with surgery after a local recurrence were: T1a, 94%; T1b, 100%; T2a, 96%; and T2b, 100%. Eight (7%) of the 118 patients developed a local recurrence. There were no isolated regional or distant recurrences. The 5-year overall survival rates were: T1a, 73%; T1b, 78%; T2a, 62%; and T2b, 69%. The 5-year cause-specific survival rates were: T1a, 96%; T1b, 100%; T2a, 100%; and T2b, 100%. Two patients experienced severe complications. CONCLUSION: Patients with limited T1aN0 cancers may be treated with either transoral laser excision or RT. Those with more advanced T1-T2N0 cancers are treated with definitive RT. We do not advocate elective nodal irradiation, even for those with bulky T2B malignancies. The addition of concomitant weekly cisplatin 30 mg/M² is considered for patients with T2B cancers. Open parotid laryngectomy is reserved for salvage of suitable patients with a local recurrence.
