Relapse in medulloblastoma: what can be done after abandoning high-dose chemotherapy? A mono-institutional experience

Purpose

We retrospectively report strategies used for medulloblastoma patients progressing after craniospinal irradiation where we aimed for: symptom control, a satisfactory quality of life, accrual in phase 1–2 trials, when available, and the first two conditions could no longer be satisfied by already experienced second-line strategies.

Methods

Surgery was used in cases of doubtful relapse or when only one site was affected. Radiotherapy was given whenever possible, especially to relieve symptoms. The main chemotherapy regimens were oral temozolomide/etoposide, intravenous (iv.) cisplatin/etoposide, iv. gemcitabine/oxaliplatin, an oral sonic hedgehog pathway inhibitor and oral melphalan.

Results

Between 1998 and 2011, we treated 18 patients relapsed after median 20 months. Nine had relapsed locally, four had dissemination, three single metastases, and two had one synchronous local and metastatic recurrence. Responses to chemotherapy were seen in 32 % of cases. The median hospital stay for treatments/complications was 19 days. The 1- and 3-year progression-free survival (PFS) rates were 28?±?10 % and 0 %, respectively, for OS, they were 44?±?12 % and 22?±?10 % but no patient was cured. The median PFS after a first relapse was 7 months (range 1–29); the median OS was 7 months (range 4–44). No patients died due to treatment toxicity. Late recurrence (more than 1–2 years after diagnosis) and involvement of single sites were favorable prognostic factors.

Conclusions

Without succeeding in patients cure, we ensured them further treatment with short hospital stay thus affording low personal and social costs. The chances of cure may emerge from tailored therapies according to genetic stratification.

Long-term evaluation of postoperative acromegalic patients in remission with previous and newly proposed criteria

Criteria to define remission of acromegaly have changed over years. Since 2000, criteria for cure are normal IGF-I levels and a nadir GH after oral glucose tolerance test (OGTT) of less than 1 microg/liter, although recent studies have suggested to lower this cutoff value. This study reevaluated long-term disease activity of acromegalic patients, who were previously considered in remission, using these criteria. The study included 70 of 146 patients operated on between 1984 and 1996 who were considered cured based on normal IGF-I levels, GH values less than 2.5 microg/liter, and/or disappearance of abnormal GH response to TRH/GnRH. Among these 70 patients, 16 were lost to follow-up, three died, and 11 (one of whom had disease recurrence) only gave a phone interview. Forty patients participated in the study and were reevaluated for IGF-I levels and post-OGTT GH nadir after 14.3 +/- 4.2 (mean +/- sd) yr from surgery. In all patients, normal IGF-I levels and a post-OGTT GH nadir of less than 1 microg/liter were found. In particular, 19 patients had a GH nadir of less than 0.19 microg/liter, i.e. the upper limit (mean + 2 sd) found in 30 controls, whereas 21 patients had a nadir between 0.19 and 0.77 microg/liter. No significant differences in hormonal parameters and comorbidities between the two subgroups were observed. These data showed that lowering the post-OGTT GH cutoff value within the normal range does not seem to better discriminate patients with different disease activity or long-term recurrence risk.
