Recurrence Pattern, Treatment Modalities, and Prognostic Factors After Definitive Chemoradiotherapy for Recurrent Esophageal Cancer.

BACKGROUND: Recurrent esophageal cancer (EC) has a poor prognosis. However, the recurrence patterns and therapeutic outcomes after definitive chemoradiotherapy (CRT) are not fully understood. We analyzed survival and prognostic factors associated with post-definitive CRT recurrent EC. METHODS: We retrospectively reviewed 71 consecutive patients with post-definitive CRT EC recurrence between 2008 and 2021 at our institution. Recurrence was locoregional, distant, and combined in 42 (59%), 18 (25%), and 11 (16%) patients, respectively. The median time from definitive CRT to recurrence was 8.3 months. Treatment modalities included local therapy, systemic therapy, and palliative care. Overall survival (OS) after recurrence was analyzed using the Kaplan-Meier and Cox proportional hazards models. RESULTS: The median follow-up time from recurrence was 7.1 months, and the median survival time (MST) was 12.5 months. In the univariate analysis, longer time to recurrence, earlier stage at initial treatment, surgical tolerance at initial diagnosis, treatment modalities, and oligo-recurrence were associated with a better prognosis. The MST of the local therapy, systemic therapy, and palliative care groups were not reached, 11.8 months and 4.1 months, respectively (P < 0.001). In the multivariate analysis, treatment modalities and oligo-recurrence emerged as independent prognostic factors (P < 0.001 and P = 0.009). CONCLUSIONS: Aggressive local therapy should be considered to improve the prognosis for patients with oligo-recurrence and/or indication of local therapy to treat recurrent EC.

Abscopal Effect after Stereotactic Body Radiotherapy with Nivolumab for Lung Metastasis of Head and Neck Cancer: A Case Report.

Introduction: The abscopal effect (AE) is a phenomenon, in which radiotherapy exerts an antitumour effect on distant lesions outside the primary irradiated area. Although immune checkpoint inhibitors have been widely studied for their potential to enhance the AE and improve patient outcomes, findings in cases of head and neck cancers remain limited. Case Presentation: We report the case of a 72-year-old man who experienced lung oligoprogression during nivolumab treatment for metastatic hypopharyngeal cancer. Stereotactic body radiotherapy (SBRT) was administered to one of the lung lesions, after which both irradiated and nonirradiated lesions regressed. Upon an 18-month follow-up period after SBRT, the patient showed no disease progression or toxicity, and continued receiving nivolumab therapy. Conclusion: The intent behind presenting this case report was to contribute to the accumulation of evidence regarding the AE in cases of head and neck cancer.

Clinical Outcomes of Radiotherapy for Stage 1 Glottic Carcinoma: Comparing Accelerated Hyperfractionation and Once-daily Fractionation.

BACKGROUND/AIM: Accelerated hyperfractionation (AHF) is used in head and neck cancer to improve the local control (LC) rate, but reports of outcomes for early-stage GC are limited. The outcomes of radiotherapy (RT) for stage 1 glottic carcinoma (GC) were retrospectively analyzed, comparing AHF and once-daily fractionation (ODF) using 2.0-2.4 Gy. PATIENTS AND METHODS: A total of 102 patients with stage 1 GC underwent RT alone between 2007 and 2021, with 43 in the AHF group and 59 in the ODF group. A p-value less than 0.05 was considered to indicate a significant difference. RESULTS: The 5-year LC rate was 98% in the AHF group and 91% in the ODF group (p=0.19). During RT, significantly more patients in the AHF group required opioids due to mucositis than in the ODF group (74% vs. 25%, p<0.001), and the rate of aspiration pneumonia tended to be higher in the AHF group than in the ODF group (7% vs. 0%, p=0.072). CONCLUSION: There was no difference in the LC rate between AHF and ODF for stage 1 GC. Moreover, the AHF group required opioids at a higher rate and tended to have a higher risk of developing aspiration pneumonia.

The efficacy of radiation therapy using the Quad Shot regimen in cutaneous metastasis from parotid gland cancer: A case report.

Cutaneous metastasis from malignant tumors can cause symptoms such as exudates, bleeding, and pain, which remarkably reduce patient's quality of life. Herein, we report a case in which radiation therapy using the Quad Shot regimen was effective in the treatment of cutaneous metastasis from parotid gland cancer.

Successful Preoperative QUAD SHOT for Bulky Parotid Carcinoma: Potential Preoperative Ultra-Hypofractionated Radiotherapy for Conversion Surgery.

QUAD SHOT is an ultra-hypofractionated radiotherapy (RT) technique that prescribes 14.0-14.8 Gy over 2 days. Although this technique has already gained some status as an effective palliative treatment for inoperable head and neck cancer (HNC), its application in other situations has not been given much consideration. Herein, we report a case of a 62-year-old woman who received preoperative QUAD SHOT therapy for poorly differentiated parotid carcinoma. In this case, after two courses of QUAD SHOT plus a standard chemotherapy regimen with pembrolizumab, the patient's inoperable, bulky tumor shrank dramatically and became operable. Best of all, while adequate therapeutic effects were achieved, the patient's time commitment and physical exertion were limited. RT during this period consisted of only eight fractions over 4 days. According to previous reports, the response rate for QUAD SHOT is sufficiently high, and the rate of serious adverse events is quite low. This case asks the question of whether the indications for QUAD SHOT irradiation can be expanded as one of the preoperative interventions undertaken by HNC surgeons to achieve conversion surgery.

Nintedanib-Induced Delayed Mucosal Healing after Adjuvant Radiation in a Case of Oropharyngeal Carcinoma.

Since the launch of imatinib in 2001, tyrosine kinase inhibitors are being used in chemotherapy for a wide range of malignant tumors. Drugs that inactivate multiple molecular mechanisms are called multikinase inhibitors (MKIs). Nintedanib is a type of MKI that inhibits downstream cascades in three systems: vascular endothelial growth factor receptor, fibroblast growth factor receptor, and platelet-derived growth factor receptor inhibitions. It was initially developed as an anticancer drug for non-small-cell lung carcinoma; however, it was also found to inhibit the proliferation of fibroblasts associated with chronic inflammation in the lungs. Therefore, it is being more widely used to treat idiopathic pulmonary fibrosis, a benign disease, than as an antineoplastic agent. Several studies have reported adverse events associated with the concurrent use of MKIs with surgery or radiotherapy. Specifically, there has been a report cautioning against delayed wound healing associated with the use of nintedanib in patients undergoing surgery. However, there is no specific mention of its concurrent use during irradiation. We describe a case of a 72-year-old man with severely delayed recovery from radiation mucositis when nintedanib was being administered for benign disease.

Radiation Myelopathy Caused by Palliative Radiotherapy and Intrathecal Methotrexate.

Radiation myelopathy is a rare, late-stage adverse event that develops following irradiation at or above 50 Gy. Here, we report a case of irreversible paraplegia caused by palliative radiation (20 Gy in 5 fractions) to the spinal cord combined with intrathecal methotrexate (IT-MTX). A 69-year-old man presented with back pain, prompting a diagnosis of acute myeloid leukemia. At the first visit, he complained of muscle weakness and hypoesthesia in both legs; spinal magnetic resonance imaging (MRI) revealed an epidural mass compressing the spinal cord at the fifth to seventh level of the thoracic vertebrae. This was considered to be an extramedullary lesion of leukemia, and he received remission induction therapy including IT-MTX; palliative radiation (20 Gy in 5 fractions) of the epidural mass was initiated the following day. Then, during the course of consolidation therapy, a second IT-MTX was performed after 1 month and a third after 3 months. While the consolidation therapy was complete, yielding remission, he developed sudden paraplegia, as well as bladder and bowel dysfunction (BBD), 10 months later. Spinal MRI showed extensive intramedullary high signal intensity on T2-weighted image, including the irradiation field. It was thought myelopathy was due to irradiation of the spinal cord combined with IT-MTX. He immediately received steroid pulse therapy; however, the paraplegia and BBD did not improve. It is extremely rare for irreversible radiation myelopathy to occur with IT-MTX and palliative radiation to the spinal cord. We believe that even with low-dose palliative radiation, caution is required for combined use with IT-MTX.

Dosimetric Evaluation of the Uterus in Patients Receiving Total Body Irradiation with Ovarian Shielding.

Infertility is a well-known late complication in patients receiving hematopoietic stem cell transplantation (HSCT). We previously reported that total body irradiation (TBI) with ovarian shielding reduces the radiation dose to the ovaries to 2.4 Gy - one-fifth of the dose compared to conventional TBI - and preserves fertility without increasing the risk of relapse. Exposure to the uterus and ovaries can reportedly affect pregnancy and childbirth. However, the dose constraint of the uterus that causes infertility remains unknown. Herein, we report the pregnancy and birth outcomes of 2 patients who gave birth following TBI with ovarian shielding and evaluated the dose to the uterus using a dose-volume histogram. Case 1 involved a 30-year-old woman with acute myeloid leukemia who underwent HSCT at 21 years of age with a uterus mean dose (D mean) of 7.0 Gy. She had a natural pregnancy and elective cesarean section at 38 weeks of gestation due to hypertensive disorders of pregnancy. She gave birth to a normal-birthweight infant. Case 2 involved a 32-year-old woman with T-cell acute lymphoblastic leukemia who underwent HSCT at 30 years of age with a uterus D mean of 7.6 Gy. Her baby was delivered at full term with normal birthweight. These results indicate that a uterus D mean between 7.0 and 7.6 Gy does not have a significant impact on pregnancy and delivery with the ovarian function being preserved for patients who received TBI with ovarian shielding after puberty.

Palliative Radiotherapy Provided Good Pain Relief for Painful Adrenal Metastasis.

Adrenal metastases often occur in patients with metastasized lung cancer, but symptoms rarely develop. A 45-year-old man presented with right abdominal pain requiring strong opioids due to large right adrenal metastasis of lung adenocarcinoma. The tumor was 7.3 × 5.6 × 8.4 cm in size. He was treated with palliative radiotherapy (RT) up to 39 Gy in 13 fractions for this lesion without severe adverse effects. After RT, he had good pain relief, and opioids were no longer needed. Palliative RT for a large adrenal tumor can provide a good analgesic effect without relevant toxicity.

Comparison of Clinical Outcomes of Definitive and Postoperative Radiotherapy for Adenoid Cystic Carcinoma of the Head and Neck: Can Definitive Radiotherapy Be a Treatment Option?

BACKGROUND: The standard treatment for adenoid cystic carcinoma of the head and neck is surgical resection followed by postoperative radiotherapy (PORT). Currently, definitive radiotherapy (defRT) is considered an inadequate treatment; however, its data are based on studies using classical radiotherapy techniques. Therefore, the therapeutic effects of current radiotherapy techniques have not been adequately evaluated, and it may have underestimated the efficacy of defRT. METHODS: We retrospectively analyzed 44 adenoid cystic carcinoma patients treated with radiotherapy based on modern treatment techniques from 1993 to 2017. RESULTS: Twenty-four patients underwent PORT and 20 patients underwent defRT. The 5-year overall survival rates for patients treated with PORT and defRT were 85.3% and 79.7%, respectively. The 5-year local control rates were 82.5% and 83.1%, respectively. There were no statistically significant differences in the overall survival and local control of patients treated with PORT and defRT (p = 0.4392 and p = 0.0904, respectively). CONCLUSION: Our results show that defRT is comparable to surgical resection followed by PORT with respect to overall survival and local control. The results suggest that defRT can be an effective treatment option for adenoid cystic carcinoma of the head and neck.

Dosimetric evaluation of ovaries and pelvic bones associated with clinical outcomes in patients receiving total body irradiation with ovarian shielding.

Total body irradiation (TBI) with ovarian shielding is expected to preserve fertility among hematopoietic stem cell transplant (HSCT) patients with myeloablative TBI-based regimens. However, the radiation dose to the ovaries that preserves ovarian function in TBI remains poorly understood. Furthermore, it is uncertain whether the dose to the shielded organs is associated with relapse risk. Here, we retrospectively evaluated the relationship between fertility and the dose to the ovaries, and between relapse risk and the dose to the pelvic bones. A total of 20 patients (median age, 23 years) with standard-risk hematologic diseases were included. Median follow-up duration was 31.9 months. The TBI prescribed dose was 12 Gy in six fractions for three days. Patients' ovaries were shielded with cylinder-type lead blocks. The dose-volume parameters (D98% and Dmean) in the ovaries and the pelvic bones were extracted from the dose-volume histogram (DVH). The mean ovary Dmean for all patients was 2.4 Gy, and 18 patients recovered menstruation (90%). The mean ovary Dmean for patients with menstrual recovery and without recovery were 2.4 Gy and 2.4 Gy, respectively, with no significant difference (P = 0.998). Hematological relapse was observed in five patients. The mean pelvis Dmean and pelvis D98% for relapse and non-relapse patients were 11.6 Gy and 11.7 Gy and 5.6 Gy and 5.3 Gy, respectively. Both parameters showed no significant difference (P = 0.827, 0.807). In conclusion, TBI with ovarian shielding reduced the radiation dose to the ovaries to 2.4 Gy, and preserved fertility without increasing the risk of relapse.

Severe esophageal stenosis in a patient with metastatic colon cancer following palliative radiotherapy, ramucirumab, and chemotherapy.

Antiangiogenic agents, such as ramucirumab, should be cautiously administered along with radiotherapy because of the enhanced risk of adverse events.

Dose-volume Histogram-based Predictors for Hematuria and Rectal Hemorrhage in Patients Receiving Radiotherapy After Radical Prostatectomy.

AIM: The aim of this study was to evaluate the dose-volume histogram parameters for late hematuria and rectal hemorrhage in patients receiving radiotherapy after radical prostatectomy. PATIENTS AND METHODS: Data of 86 patients treated between January 2006 and June 2019 were retrospectively evaluated. The median radiation dose was 64 Gy in 32 fractions. Receiver operating characteristic (ROC) curves were used to identify optimal cut-off values for late adverse events. RESULTS: Eleven patients experienced hematuria, and the 5-year cumulative rate was 18%. Four patients experienced rectal hemorrhage, and the 5-year cumulative rate was 7%. ROC curve analysis demonstrated the following significant cut-off values: bladder V50 Gy: 43% (p=0.02) and V40 Gy: 50% (p=0.03) for hematuria, and rectum V60 Gy: 13% (p=0.04) and V50 Gy: 33% (p=0.03) for rectal hemorrhage. CONCLUSION: This is the first study to identify dose constraints that may reduce hematuria and rectal hemorrhage in patients receiving radiotherapy in the postoperative setting.

Carbon-ion Radiotherapy for Isolated Lymph Node Metastasis After Surgery or Radiotherapy for Lung Cancer.

Purpose: Mediastinal and hilar lymph node metastasis is one of the recurrence patterns after definitive treatment of lung cancer. Salvage radiotherapy (RT) can be a treatment option for lymph node metastasis. However, the usefulness of additional RT remains unclear after surgery or RT for the primary lung tumor. We retrospectively evaluated the efficacy and safety of hypofractionated carbon-ion RT for isolated lymph node metastasis. Methods and Materials: Between April 2013 and August 2016, 15 consecutive patients with isolated lymph node metastasis underwent carbon-ion RT. The pretreatment evaluations confirmed the isolated lymph node metastasis and the absence of local recurrence or distant metastasis, which was oligometastatic disease. The median age was 72 (range, 51-83) years, with 11 male patients. The first treatments for primary lung tumors were carbon-ion RT for 8 patients and surgery for 7 patients. There were 9 adenocarcinomas, 4 squamous cell carcinomas, 1 adenosquamous cell carcinoma, and 1 mucoepidermoid carcinoma. Most patients (93%) were irradiated with 52.8 Gy relative biological effectiveness in 12 fractions for 3 weeks. There were no patients treated with concurrent or adjuvant therapy such as chemotherapy, molecular-targeted therapy, or immunotherapy. Adverse events were evaluated according to the Common Terminology Criteria for Adverse Events (version 4.0). Results: The median follow-up for surviving patients was 28 months. One patient experienced local lymph node recurrence, and the 2-year local control rate was 92% for all patients. Distant metastasis was observed in 7 patients, and 2-year progression-free survival rate was 47%. During follow-up, there were 4 deaths from lung cancer, and the 2-year overall survival rate was 75%. There were 2 patients with acute grade 2 esophagitis and 2 with late grade 2 cough, which were improved by conservative therapy. There were no other grade 2 or higher adverse events. Conclusions: Hypofractionated carbon-ion RT showed excellent local control and overall survival without severe toxicities in lung cancer patients with isolated lymph node metastasis after surgery or carbon-ion RT for primary lung tumors. A multi-institutional prospective study is required to establish the efficacy and safety of carbon-ion RT.

Updated Clinical Outcomes of Hematopoietic Stem Cell Transplantation Using Myeloablative Total Body Irradiation with Ovarian Shielding to Preserve Fertility.

Myeloablative conditioning regimens are associated with severe gonadal toxicity. To preserve ovarian function, we have been investigating ovarian shielding during total body irradiation (TBI) with a myeloablative dose. In this report, we update the clinical outcomes. Female patients with standard-risk hematologic diseases, aged 40 years or younger, who desired to have children, were included (n = 19). The conditioning regimen consisted of TBI at 12 Gy with ovarian shielding and cyclophosphamide (120 mg/kg) or cytarabine (24 g/m2). Ovarian shielding reduced the actual irradiation dose applied to the ovaries from 12 Gy to 2 to 3 Gy. The median age at hematopoietic stem cell transplantation (HSCT) was 24 years (range, 19 to 33 years). With a median follow-up period of 1449 days (range, 64 to 3694) after HSCT, 5-year overall survival and 1- and 5-year relapse rates were 67%, 17%, and 31%, respectively. Only 2 of 14 patients with acute myeloid or lymphoid leukemia in remission have relapsed thus far. The 6-month and 1-year cumulative rates of menstrual recovery were 42% and 78%, respectively. In all patients with menstrual recovery, menstruation recovered within 1 year. The serum anti-Müllerian hormone (AMH) level tended to gradually increase after menstrual recovery. Three patients with extensive chronic graft-versus-host disease experienced delayed recovery of menstruation and serum AMH. Five pregnancies in 3 patients resulted in normal delivery in 1, selective cesarean operation in 1, current pregnancy in 1, and natural abortion in 2. These results suggest that a myeloablative TBI regimen with ovarian shielding could preserve fertility after HSCT without an apparent increase in relapse in standard-risk patients. Because serum AMH recovered gradually over time, the AMH level during the early phase after HSCT may have little value as a marker of ovarian reserve.

Prospective Study of Isolated Recurrent Tumor Re-irradiation With Carbon-Ion Beams.

Purpose: To perform a prospective study to evaluate the efficacy and safety of isolated recurrent tumor re-irradiation with carbon-ion radiotherapy (RT). Methods and Materials: The inclusion criteria were clinically proven recurrent tumors, measurable by computed tomography or magnetic resonance imaging, patients ≥ 16 years old, performance status scores between 0 and 2, isolated tumor at a previously irradiated site, and a life expectancy > 6 months. The exclusion criteria were tumor invasion into the gastrointestinal tract or a major blood vessel, uncontrolled infection, early recurrence (<3 months), and severe concomitant diseases. The primary end-point was the local control rate, the secondary end-points including the overall survival rate, and adverse events. Results: Between December 2013 and March 2016, 22 patients were enrolled in this prospective study. All patients were re-irradiated with carbon-ion RT with radical intent. Five patients had rectal cancer, 4 had sarcoma, 4 had lung cancer, 3 had hepatic cell carcinoma, and 6 had other tumors. The median follow-up time was 26 months. Eight patients developed local recurrence, and the 1- and 2-year local control rates were 71 and 60%, respectively. Eight patients died of their cancers and 2 died of other diseases. The 1- and 2-year overall survival rates were 76 and 67%, respectively. There were no grade 2 or higher acute adverse events and 4 patients (18%) developed grade 3 late adverse events. The group with the longer interval (>16 months) between the first RT and re-irradiation had significantly better outcomes than the shorter interval group (≤ 16 months). Conclusions: Re-irradiation, using carbon-ion RT with radical intent, had favorable local control and overall survival rates without severe toxicities for selected patients. Re-irradiation has the potential to improve clinical outcomes for isolated, local, recurrent tumors; further investigations are required to confirm the therapeutic efficacy.

Damage to sebaceous gland and the efficacy of moisturizer after whole breast radiotherapy: a randomized controlled trial.

BACKGROUND: We conducted a randomized trial to evaluate the efficacy of heparinoid moisturization for radiation dermatitis. We report the time-course of sebum content after whole breast radiotherapy (WBRT) and the efficacy of heparinoid moisturizer. METHODS: Patients receiving adjuvant breast RT were randomly assigned into three groups; prophylaxis, post-WBRT and control groups. Patients used moisturizer on the irradiated breast from the beginning of RT in the prophylaxis group, 2 weeks post-RT in the post-WBRT group, and no moisturizer in the control group. Sebum content of the irradiated and non-irradiated breast was measured to assess sebaceous gland damage. Sebum composition was also analyzed. RESULTS: A total of 76 patients were analyzed; 30 in the post-WBRT group, 32 in the control group, 14 in the prophylaxis group. The sebum content in the irradiated breast significantly decreased after WBRT in the post-WBRT and control groups. The decrease was sustained in the control group. In the non-irradiated breast, sebum content also decreased after WBRT in the post-WBRT and control groups. After moisturizer application, sebum content by sebumeter returned to pre-RT level in the post-WBRT group, while the decrease was sustained in the control group. Sebum content measured by evaporative light scattering detector and sebumeter was similar in the control group, but the dissociation was observed after moisturizer application in the post-WBRT group. The proportion of wax esters decreased in the irradiated breast after WBRT. CONCLUSIONS: Radiotherapy significantly reduced sebum content in both irradiated and non-irradiated breast, indicating that RT caused quantifiably persistent sebaceous gland damage in irradiated sites and the surrounding tissue. Combined with the results from our previous study, heparinoid moisturizer treatment effectively prevents water loss by retaining oil contents on the skin surface.

Results of a nationwide survey on Japanese clinical practice in breast-conserving radiotherapy for breast cancer.

The Breast Cancer Group of the Japanese Radiation Oncology Study Group conducted a nationwide questionnaire survey on the clinical practice of postoperative radiotherapy for breast-conserving treatment for breast cancer. This questionnaire consisted of 18 questions pertaining to the annual number of treated patients, planning method, contouring structure, field design, dose-fractionated regimen, application of hypofractionated radiotherapy, boost irradiation, radiotherapy for synchronously bilateral breast cancer, and accelerated partial breast irradiation. The web-based questionnaire had responses from 293 Japanese hospitals. The results indicated the following: treatment planning is performed using relatively similar field designs and delivery methods; the field-in-field technique is used at more than one-third of institutes; the commonest criteria for boost irradiation is based on the surgical margin width (≤5 mm) and the second commonest criteria was age (≤40 or ≤50 years), although some facilities applied a different age criterion (>70 years) for omitting a tumor bed boost; for conventional fractionation, almost all institutes delivered 50 Gy in 25 fractions to the conserved whole breast and 10 Gy in 5 fractions to the tumor bed. This survey revealed that 43% of hospitals offered hypofractionated radiotherapy, and the most common regimens were 42.56 Gy in 16 fractions for whole-breast irradiation and 10.64 Gy in 4 fractions for boost irradiation. Almost all of the facilities irradiated both breasts simultaneously for synchronously bilateral breast cancer, and accelerated partial breast irradiation was rarely offered in Japan. This survey provided an overview of the current clinical practice of radiotherapy for breast-conserving treatment of breast cancer in Japan.

Efficacy of heparinoid moisturizer as a prophylactic agent for radiation dermatitis following radiotherapy after breast-conserving surgery: a randomized controlled trial.

BACKGROUND: The application of heparinoid moisturizer for 2 weeks following whole-breast radiotherapy (WBRT) was previously reported to significantly increase skin water content (WC) and help improve skin dryness and desquamation. The prospective open-label, randomized trial included an exploratory arm to investigate the preventive efficacy of heparinoid moisturizer for acute radiation dermatitis (ARD). METHODS: Between April 2011 and April 2013, patients receiving WBRT were assigned (1:2:2) to receive either: moisturizer for prophylaxis (group P), moisturizer starting 2 weeks after WBRT for treatment (group M), and no moisturizer (group C). This paper presents the results of comparison between the exploratory arm and no moisturizer group. Skin WC was measured prior to WBRT, on the last day of WBRT, and 2 weeks, 4 weeks and 3 months following WBRT. Signs and symptoms were also assessed. RESULTS: Comparing two groups, WC values were significantly higher in group P until 4 weeks following WBRT. At 2 weeks following WBRT, mean WC values in group P and C were 38.5 ± 6.1 arbitrary units (a.u.) and 30.2 ± 7.8 a.u., respectively (P < 0.001). In group C, dryness was more severe at 2 and 4 weeks following WBRT and desquamation more severe until 3 months following WBRT. However, the erythema score showed no difference between the two groups. Regarding symptoms, group C pain scores on the last day of WBRT were significantly higher than in group P (P < 0.030). CONCLUSIONS: The preventive application of heparinoid moisturizer has the potential of reducing skin desquamation and dryness in patients receiving WBRT.

Haploidentical hematopoietic cell transplantation for disseminated Ewing sarcoma.

We describe the case of a 13-year-old girl with multifocal disseminated Ewing sarcoma family of tumor (ESFT) who received a 5/8 human leukocyte antigen-matched haploidentical hematopoietic cell transplantation to generate a graft-versus-tumor effect. The patient had grade 2 acute graft-versus-host disease (GVHD) of the skin and chronic GVHD nausea and abdominal pain that required prednisolone for 17 months, but has been free from ESFT for 3 years 10 months after therapy. The present case suggests a beneficial effect of haploidentical hematopoietic cell transplantation in disseminated ESFT.
