High-dose chemotherapy (HDC) followed by autologous stem cell transplantation (ASCT) improves survival in myeloma (MM). The role of induction therapy on outcomes of ASCT in MM has not been systematically studied. Nonmyelosuppressive (NMS) steroid-based induction can be used in MM, with the potential of reducing neutropenias and other toxic effects prior to ASCT. NMS induction however could be associated with poorer outcomes if disease control or stem cell collection were inadequate. We studied outcomes of 136 MM patients who underwent HDC and ASCT as part of their initial therapy between March 1998 and December 2000. Of these, 46 received HDC and ASCT without any exposure to myelosuppressive agents, 39 received myelosuppressive therapy for disease control and/or stem cell collection, and 51 received alkylating agent-based initial treatment. We compared OS and EFS rates, stem cell collectability, and contamination of the grafts with monoclonal plasma cells. After a median of 33 months, response rates, EFS and OS rates were comparable in the three groups of patients. Adequacy of stem cell collection and plasma cell contamination were similar. Our data support the hypothesis that NMS induction for patients with MM is safe and effective and does not compromise the results of HDC.
If a clinician seeks to allow patients with vertigo to return to work as soon as possible, it is very important to determine the appearance of vestibular symptoms during convalescence just after treatment, as well as the long-term results. Apprehensive patients with vertigo may undergo severe psychological torment if treatment requires long-term rest in bed before they can return to daily life. In this paper, we observed postoperative vestibular symptoms (subjective sensation and objective nystagmus) in 50 patients with intractable Meniere's disease, including cases from our previous preliminary report, during the period of convalescence just after endolymphatic sac drainage and steroid instillation surgery (EDSS). All symptoms were eliminated within 8 days after EDSS. There was no significant difference in the duration of any vestibular symptoms between bilateral (n = 8) and unilateral cases (n = 42). This result indicates that EDSS could be as safe a treatment for bilateral Meniere's disease as for unilateral disease. In unilateral cases with intact semicircular canal function (n = 17), postoperative evoked vestibular sensation, positional, and positioning (Dix-Hallpike) nystagmus disappeared significantly earlier than in those with canal paresis (n = 25). This result indicates that EDSS could keep the vestibular peripheral function of patients with unilateral Meniere's disease with intact canals quite stable after surgery. Therefore, EDSS could be recommended as an initial, less-invasive surgical treatment for intractable Meniere's disease, especially in unilateral cases with intact canals and in bilateral cases.
