    The Tokai Study Group for Therapeutic Radiology and Oncology (TOSTRO) started managing T1 glottic cancer using 2.25 Gy/fraction radiotherapy in 2011. The aim was to evaluate the local control (LC) rate and toxicity with 2.25-Gy radiotherapy in clinical practice and identify prognostic factors.The eligibility criteria were T1 glottic squamous cell carcinoma patients with age ≥20 years, treated with 2.25 Gy/fraction without chemotherapy between 2011 and 2017. LC rates were evaluated based on age, performance status, sex, T-category, tumor type (ulcerative or non-ulcerative), presence of anterior commissure invasion, tumor size, X-ray beam energy, and overall treatment time. Acute and late adverse events were evaluated using CTCAE version 4.0. A total of 202 patients were enrolled. The median follow-up period was 34.2 months. The 2 and 4-year LC rates were 93.8% and 93.1%, respectively. There was a significant difference in the LC rate between non-ulcerative type and ulcerative type (95.2% vs. 74.1% at 2 years, 94.4% vs. 74.1% at 4 years; p = 0.01). On univariate analysis, only tumor type was significantly correlated with a poor LC rate (hazard ratio 4.3; 95% confidence interval 1.2–15.4; p = 0.03). Acute grade 3 adverse events occurred in 17 patients. However, no late adverse events of grade 3 or higher have occurred to date. T1 glottic cancer treatment outcomes using hypofractionated radiotherapy with 2.25 Gy/fraction in clinical practice were comparable to previously reported results. However, ulcerative type tumor was associated with a poor LC rate.

    Background: Standard treatments for small cell carcinoma of the cervix (SCCC) have not been established. In this study, we aimed to estimate the optimal treatment strategy for SCCC. Methods: This was a multicenter retrospective study. Medical records of patients with pathologically proven SCCC treated between 2003 and 2016 were retrospectively analyzed. Overall survival (OS) was plotted using the Kaplan-Meier method. Log-rank tests and Cox regression analysis were used to assess the differences in survival according to stage, treatment strategy, and chemotherapy regimen. Results: Data of 78 patients were collected, and after excluding patients without immunohistopathological staining, 65 patients were evaluated. The median age of the included patients was 47 (range: 24–83) years. The numbers of patients with International Federation of Gynecology and Obstetrics (FIGO) 2018 stages I-IIA, IIB-IVA, IVB were 23 (35%), 34 (52%), and 8 (12%), respectively. Of 53 patients who had undergone chemotherapy, 35 and 18 received SCCC and non-SCCC regimens as their first-line chemotherapy regimen, respectively. The 5-year OS for all patients was 49%, while for patients with FIGO stages I-IIA, IIB-IVA, IVB, it was 60, 50, and 0%, respectively. The 5-year OS rates for patients who underwent treatment with SCCC versus non-SCCC regimens were 59 and 13% (p < 0.01), respectively. This trend was pronounced in locally advanced stages. Multivariate analysis showed that FIGO IVB at initial diagnosis was a significant prognostic factor in all patients. Among the 53 patients who received chemotherapy, the SCCC regimen was associated with significantly better 5-year OS in both the uni- and multivariate analyses. Conclusion: Our results suggest that the application of an SCCC regimen such as EP or IP as first-line chemotherapy for patients with locally advanced SCCC may play a key role in OS. These findings need to be validated in future nationwide, prospective clinical studies.

    Objective: We aimed to report the 2-year results of stereotactic body radiation therapy for prostate cancer and identify the clinical and dosimetric factors that predict acute genitourinary toxicities. Methods: We retrospectively reviewed the medical records of patients with non-metastatic prostate cancer treated at Toyota Memorial Hospital between 2017 and 2020. The patients were treated with stereotactic body radiation therapy with a total dose of 36.25 Gy in five fractions on consecutive weekdays. While low-risk patients received radiotherapy alone, intermediate- to high-risk patients also received androgen deprivation therapy. Results: We analysed a total of 104 patients, including 10, 60 and 34 low-, intermediate- and high-risk patients, respectively. The median follow-up duration was 2 years. We did not observe biochemical/clinical recurrence, distant metastasis or death from prostate cancer. One patient died of another cause. Grade 2 acute genitourinary toxicity was observed in 40 (38%) patients. Age (P = 0.021), genitourinary toxicity of grade ≥1 at baseline (P = 0.023) and bladder mean dose (P = 0.047) were significantly associated with the incidence of grade 2 acute genitourinary toxicity. The cut-off value of 65 years for age and 10.3 Gy for the bladder mean dose were considered the most appropriate. Grade 2 acute gastrointestinal toxicity was observed in five (5%) patients. None of the patients experienced grade ≥3 acute or late toxicity. Conclusions: Stereotactic body radiation therapy is feasible for Japanese patients with prostate cancer, with acceptable acute toxicity. Age, genitourinary toxicity at baseline and bladder mean dose predict grade 2 acute genitourinary toxicity.

    <p>Here, we describe the case of a 14-month-old boy with a left retroperitoneal tumor that was diagnosed as stage 3 neuroblastoma (image-defined risk-factor-positive, <i>MYCN</i> amplified). He underwent five courses of induction chemotherapy and high-dose chemotherapy comprising busulfan+melphalan, followed by autologous bone marrow transplantation. On day 72 after transplantation, he underwent partial resection, and a histopathological analysis showed surviving viable tumor cells. On day 77, computed tomography (CT) scan showed progression of the primary tumor. Although salvage therapy was performed, CT scan on day 100 showed multiple pleural metastases. Local irradiation of the primary tumor (30.6 Gy/17 fractions) and whole lungs (15 Gy/10 fractions) was also performed. Peritoneal dissemination occurred and he died on day 207. Post-autopsy analysis showed high expression levels of ALK in the primary tumor and autopsy specimens. Neuroblastoma with <i>MYCN</i> amplification and high expression levels of ALK can result in rapid exacerbation, and the introduction of new agents such as ALK inhibitors is warranted.</p>

    放射線治療は悪性神経膠腫の主な治療法の1つである。悪性神経膠腫は広がりやすい特徴があるため、画像で分かる腫瘍から大きくマージンを広げた範囲を標的として放射線治療が行われる。脳内は腫瘍が浸潤しにくい脳室などの構造が複雑に存在するため、マージンをどのように広げるか決定することは非常に難しく定まった方法がない。今後より標的に絞った放射線治療が行える時代が来る。それに向けより合理的で計画者間で誤差が少ないマージン付加モデルを考案した。本研究では深層学習を交えながら、モデルの安全性、有効性の検討および改良を行っていく。
