Clinical trials investigating anti-hyperphagic medications are currently underway. The Hyperphagia Questionnaire for Clinical Trials (HQ-CT) is designed to assess hyperphagia in PWS, with scores ranging from 0 to 36, where higher scores indicate greater severity. However, HQ-CT scores have not yet been evaluated in Japan. Therefore, we conducted a questionnaire-based survey among patient association members. Of 605 members, the score was available in 266. Their median age was 13 years (range: 0-48). Of these, 160 were children (<18 years), and 106 were adults (≥18 years). Obesity was observed in 11% and 40% of the pediatric and adult participants, respectively. The genetic subtypes included deletions (56%) and uniparental disomies (26%). The median HQ-CT score was 5 (range: 0-30), with no significant differences observed by sex or genetic subtype. The adult participants had significantly higher scores than pediatric participants (8 vs. 4). The HQ-CT score was lower than that reported in studies conducted overseas. Among adult participants, the score was significantly higher in obese individuals than in non-obese individuals, and multivariate analysis demonstrated a positive association between the score and body mass index, after adjusting for age, sex, genotype, and growth hormone treatment during childhood (β = 0.38, p = 0.0001).

Currently, temozolomide (TMZ) is the first-line treatment for aggressive PitNET. However, it is not yet covered by insurance in Japan. Additionally, O6-Methylguanine-DNA Methyltransferase (MGMT) expression can lead to treatment resistance, further complicating treatment selection. We previously demonstrated the effectiveness of combination therapy with capecitabine (CAPTEM) in several cases of aggressive PitNETs. The present study described our experiences with TMZ in 13 patients with aggressive PitNETs (including four patients administered CAPTEM). Pathological examination revealed eight corticotroph, four lactotroph, and one somatotroph tumors. Of these, seven patients are still receiving treatment, and six patients have terminated treatment. The reasons for discontinuation were poor efficacy (three patients), financial reasons (two patients), and patient preference (one patient). No patients required treatment discontinuation owing to adverse events. Furthermore, one case of a lactotroph tumor, which achieved remission with CAPTEM but was discontinued after three years for financial reasons, remains in remission on imaging and maintained normal PRL levels for 15 months after discontinuation. The most significant issue is off-label use.
