RESUMEN
Carriers of oncogenic human T-cell leukemia virus type 1 (HTLV-1) can develop adult T-cell leukemia/lymphoma (ATLL). While an increasing number of animal models of HTLV-1 infection have revealed that malignant tumors with a histiocytic phenotype can arise, they have not been reported in humans. Here, we present a 79-year-old female HTLV-1 carrier who presented with a swollen lymph node. Histological examination revealed that the lymph node was replaced with a malignant spindle cell tumor, but not ATLL. Immunohistochemical analysis indicated that the tumor was positive for histiocytic (CD68 and CD163) and myogenic (α-smooth muscle actin, desmin, and caldesmon) markers, suggesting some differential diagnoses. We could not reach a definitive diagnosis under the current notion of the disease entity. In addition, we could not provide an exact causal relationship between HTLV-1 infection and the development of the current tumor. Nevertheless, this tumor may be a human counterpart of murine HTLV-1-related histiocytic tumors. Curiously, the tumor showed a good response to chemotherapy with the combination of cyclophosphamide, vincristine, and prednisone, a standard approach for ATLL. This case might represent a novel entity of an HTLV-1-related malignant tumor. Further accumulation of case reports will certainly contribute to our understanding of human HTLV-1-related disease and the mechanism of viral oncogenesis.

OBJECTIVE: We conducted a questionnaire survey of oncology specialists to investigate the frequency of administration of different drugs for the management of chemotherapy-induced peripheral neuropathy in Japan in 2015. Our group published Clinical Guidelines for the Management of Chemotherapy-Induced Peripheral Neuropathy in 2017 (CIPN-GL2017). In these guidelines, we recommended duloxetine only. To verify the effect of the publication of the CIPN-GL2017, we conducted a questionnaire survey in 2019. METHODS: In 2015 and again in 2019, we investigated the use of vitamin B12, antiepileptic agents, duloxetine, antidepressants other than duloxetine, non-steroidal anti-inflammatory drugs, opioids and the Kampo compound (goshajinkigan) in a questionnaire employing a three-point scale wherein A implies routine or prophylactic administration, B implies occasional administration and C implies infrequent administration. RESULTS: We sent the questionnaires via email to 971 diplomates of the Subspecialty Board of Japanese Society of Medical Oncology in 2015 and 1239 diplomates in 2019. The administration ratio (A + B) of duloxetine for numbness and pain was 46.8 and 31.7%, respectively, in 2015 and 68.9% (P < 0.01) and 73.1% (P < 0.01) in 2019. In response to the question regarding awareness of the CIPN-GL2017, 53.2% of respondents to the 2019 questionnaire were aware of the CIPN-GL2017. Among the respondents with an awareness of the CIPN-GL2017, the prescription rate of duloxetine (78.3%) for pain was significantly higher than that among respondents without any awareness (67.4%). CONCLUSIONS: It is possible that the publication of CIPN-GL2017 influenced administration preferences of oncology specialists.

We report the case of a 61-year-old woman with a collision cancer of primary squamous cell carcinoma (SCC) and adenocarcinoma in the stomach that was cured surgically. She achieved complete remission after treatment (R-CHOP and radiation therapy;40.8Gy/22Fr) for a non-Hodgkin's lymphoma of diffuse large B cell type from September 2016 to April 2017. In August 2018, endoscopic findings showed a type 3 tumor with a white coat on the posterior wall of the upper gastric body. A biopsied specimen showed that the tumor was a SCC. Total gastrectomy, distal pancreatectomy, splenectomy, and D2 lymph node dissection were performed. Pathological examination showed a SCC invasion to the spleen, and normal gastric mucosa between the esophagus and SCC of the stomach. Based on the pathological TNM classification, the tumors were T4N1M0 (Stage IIIB) for the SCC and T1N0M0 (Stage IA) for the adenocarcinoma of the stomach. The patient received adjuvant chemotherapy with S-1, and was recurrence free at 9 months after the surgery.

BACKGROUND: The purpose of this study was to detect background factors that might be associated with the therapeutic and curative outcome of chemotherapy in elderly cancer patients aged over 75 years. METHODS: A retrospective study was conducted for elderly cancer patients aged over 75 years who had received more than 2 courses of chemotherapy at our hospital. We analyzed the relationships between RECIST outcome and background factors, such as age, sex, clinical TNM stage, pre-treatment history, ECOG performance status, serum albumin, and Charlson comorbidity index using logistic regression analysis. RESULTS: A total of 103 cancer patients aged over 75 years were analyzed in this study, including 28 with hematological neoplasia, 36 with gastrointestinal tract cancers, 25 with breast cancers, and 14 with other malignancies originating in various tissues. Seventy-one patients (69.1%) had a positive clinical outcome including RECIST CR (complete response), PR (partial response) and SD (stable disease). Multivariate analysis showed that a high serum albumin level of more than 3.5 g/dl and a Charlson comorbidity index score of less than 2 points were positively correlated with a favorable therapeutic outcome. CONCLUSIONS: The results of the current study suggested that serum albumin level and comorbidity index are the principal clinical factors affecting therapeutic outcomes in elderly cancer patients receiving chemotherapy. In the future, these factors may make chemotherapy adaptations, continuity, and effectiveness easier to predict than GA screening.

OBJECTIVE: This multicenter cooperative study aimed to analyze the adverse events (AEs) associated with tyrosine kinase inhibitors (TKIs) used as initial treatment for chronic-phase chronic myeloid leukemia (CML-CP) and their impact on outcome. METHODS: We retrospectively evaluated 450 patients with CML-CP who received TKIs between 2004 and 2014. RESULTS: The 5-year overall survival (OS) and event-free survival (EFS) rates were 95.1% and 89.0%, respectively. Patients with comorbidities (46.4%) and aged ≥60 years (50.4%) at diagnosis had significantly inferior OS to those without comorbidities and aged <60. Patients achieved higher rates of major molecular response (MMR) at 6 and 12 months after initial treatment with dasatinib or nilotinib compared to imatinib, but final MMR rates were almost the same. Sixty-six percent of patients required treatment modifications from first-line TKI therapy; the main reasons were AEs (48.4%) and failure (18%). Grade III-IV AEs in first-line TKI therapy were significantly correlated to inferior OS/EFS compared to grade 0-II AEs. CONCLUSION: Although long-term outcomes were similar in CML-CP patients treated with each TKI regardless of first-line TKI selection, severe AEs in first-line TKI therapy decreased their survival rates. Early change in TKIs is recommended, when faced with severe AEs of specific TKIs.

BACKGROUND: Mogamulizumab, a defucosylated humanized monoclonal antibody targeting C-C chemokine receptor 4, recently became available for the treatment of adult T-cell leukemia/lymphoma (ATL). We conducted a multicenter retrospective study of the efficacy of mogamulizumab in ATL treatment in patients on Hokkaido Island, Japan. MATERIALS AND METHODS: A total of 125 patients with ATL treated from January 2010 to December 2014 in 20 hospitals affiliated with the Hokkaido Hematology Study Group were enrolled in the present retrospective study. RESULTS: Of the 125 ATL patients, 62 (46.6%) presented with the acute type, 51 (38.3%) with the lymphoma type, and 12 (9.0%) with the chronic type; the latter group included 7 unfavorable chronic cases. The median age at diagnosis was 68 years (range, 35-86 years). The median survival for those with acute, lymphoma, and unfavorable chronic types was 302, 279, and 921 days, respectively. Advanced age, high lactate dehydrogenase level, poor performance status (3-4), and the existence of B symptoms were unfavorable prognostic factors for overall survival (OS). Survival rate calculated from the day of diagnosis was significantly higher in patients treated with mogamulizumab. The OS of individuals receiving hematopoietic stem cell transplantation (HSCT) was superior to that of the non-HSCT group. The median interval between the last mogamulizumab dose and allogeneic HSCT was 38 days (range, 21-53 days). Of the 22 HSCT recipients who were not treated with mogamulizumab, overall acute graft-versus-host disease (aGVHD) and grade III-IV aGVHD occurred in 12 (54.5%) and 3 (13.6%) patients, respectively. However, overall aGVHD and grade III-IV aGVHD developed in 8 (88.9%) and 3 (33.3%) of the 9 HSCT recipients treated with mogamulizumab, respectively. CONCLUSION: Mogamulizumab improves OS in patients with ATL, although its use in HSCT patients might trigger severe GVHD. Determining the optimal pre-HSCT mogamulizumab treatment regimen is thus a priority.

BACKGROUND: Various drugs are administered for the management of chemotherapy-induced peripheral neuropathy (CIPN) in Japan. However, there have been no surveys undertaken to identify these drugs or their frequency of prescription. Therefore, we administered a questionnaire survey to the diplomates of the Subspecialty Board of Japanese Society of Medical Oncology (JSMO) to investigate the frequency of administration of different drugs for the management of CIPN in Japan. METHODS: We investigated the use of vitamin B12, antiepileptic agents such as pregabalin, duloxetine, antidepressants other than duloxetine, non-steroidal anti-inflammatory drugs (NSAIDs), opioids and the Kampo compound goshajinkigan in a questionnaire employing a three-step scale wherein A implies routine or prophylactic administration, B implies occasional administration and C implies infrequent administration. RESULTS: Considering responses A and B together, the most frequently administered drugs for the treatment of numbness were antiepileptic drugs such as pregabalin (A+B=98.7%), vitamin B12 (74.7%), Kampo compounds (58.7%) and duloxetine (46.8%). The most frequently prescribed drugs for pain were NSAIDs (97.7%), followed by opioids (83.1%) and finally antiepileptic drugs (82.1%). CONCLUSIONS: Various drugs are frequently administered for CIPN. In addition, it was found that marked differences exist between the drugs targeted on numbness and pain.
RESUMEN
PURPOSE: Consolidation/maintenance therapy induces deep remission in patients with multiple myeloma (MM); however, the most suitable regimen has been under investigation. The combination therapy with bortezomib, lenalidomide and dexamethasone (VRD) is a powerful regimen for relapsed/refractory as well as newly diagnosed MM as an induction therapy. However, severe adverse events (AEs) may become a problem when VRD is introduced without dose reduction as a consolidation/maintenance therapy. METHODS: In this single-arm phase II study, we evaluated the efficacy of small-dose VRD regimen (sVRD) in the consolidation/maintenance setting. Sixteen patients who had partial response (PR) or better after any induction therapy were enrolled. Patients received at least six 28-day cycles of subcutaneous bortezomib (1.3 mg/m2 on days 1 and 15), lenalidomide (10 mg on days 1-21) and dexamethasone (40 mg on days 1, 8, 15 and 22). RESULTS: The overall response rate and the complete response (CR) rate were 100 and 43.8 %, respectively. In particular, one patient with CR and two patients with very good PR at enrollment achieved stringent CR during 6 courses of sVRD. With a median follow-up time of 29.4 months, the median progression-free survival (PFS) and overall survival (OS) were not reached, while the PFS and OS rates at 2.5 years were 66.6 and 77.3 %, respectively. Univariate analysis demonstrated that disease progression as a reason for discontinuation of sVRD had a negative impact on OS. There were no grade 3 or 4 hematologic or nonhematologic AEs. CONCLUSION: Our sVRD regimen as a consolidation/maintenance therapy was highly effective and well tolerable.

PURPOSE: The recommended dosing interval for transdermal fentanyl is every 72 h. However, some patients will have "end-of-dose failure," which may be seen as an increase of episodes of severe pain flares at the third day after application of the patch. A new once-a-day fentanyl patch was developed in Japan since 2010. This study aimed to assess the efficacy of the once-a-day fentanyl citrate patch for patients with cancer-related pain receiving the 72-h transdermal fentanyl not lasting 72 h. METHODS: We performed a cross-sectional retrospective analysis of 445 inpatients with the 72-h transdermal fentanyl at Higashi Sapporo Hospital. We could switch to the once-a-day fentanyl citrate patch if patients reported inadequate pain relief beyond 48 h after application of the 72-h transdermal fentanyl. Patients recorded baseline scores for background pain intensity (PI) and the frequency of use of daily rescue medication for breakthrough cancer pain (BTcP). RESULTS: Of all patients, 10.1% showed the increase in PI of 30% or more baseline PI on the third day after application of the 72-h transdermal fentanyl. Of patients, 84.4% were converted from equivalent dose of the 72-h transdermal fentanyl to the once-a-day fentanyl citrate patch. On the third day after switching, 60.5% of patients showed a reduction of more than 30% from baseline PI. Switching to the once-a-day fentanyl citrate patch significantly reduced the mean frequency of daily rescue dose for BTcP. CONCLUSIONS: A once-a-day fentanyl citrate patch provided stable pain control. Its use may be considered as the dominant strategy for patients receiving a 72-h transdermal fentanyl not lasting 72 h.

BACKGROUND: Chemotherapy-induced peripheral neuropathy (CIPN) is difficult to manage. A phase III trial conducted in the United States demonstrated that duloxetine was effective for CIPN caused by taxane and platinum-based chemotherapy. No randomized trial of duloxetine for CIPN has been conducted in Japan. METHODS: In this open-label, randomized, crossover study, eligible patients were randomized to Group A or Group B. Group A received duloxetine 20 mg/day orally for the first week and 40 mg/day for the next 3 weeks. Group B received vitamin B12 (VB12) 1.5 mg/day orally for 4 weeks. After a 2- to 4-week washout period, treatment was crossed over for another 4 weeks. The severity of numbness and pain was assessed using a visual analog scale (VAS). RESULTS: Thirty-four patients were enrolled. Obvious decreases in the mean VAS scores for numbness and pain were observed for the periods of duloxetine administration. Significant differences were observed between the duloxetine-first (Group A) and the VB12-first (Group B) groups with respect to numbness (p = 0.03) and pain (p = 0.04) at 4 weeks after administration. Fatigue was observed in six of the 34 participants (17.6 %). CONCLUSIONS: Our data suggests that duloxetine has a beneficial effect on CIPN caused by oxaliplatin, paclitaxel, vincristine, or bortezomib in Japanese patients.

OBJECTIVE: Continuous deep sedation (CDS) is a way to reduce conscious experience of symptoms of severe suffering in terminally ill cancer patients. However, there is wide variation in the frequency of its reported. So we conducted a retrospective analysis to assess the prevalence and features of CDS in our palliative care unit (PCU). METHODS: We performed a systemic retrospective analysis of the medical and nursing records of all 1581 cancer patients who died at the PCU at Higashi Sapporo Hospital between April 2005 and August 2011. Continuous deep sedation can only be administered safely and appropriately when a multidisciplinary team is involved in the decision-making process. Prior to administration of CDS, a multidisciplinary team conference (MDTC) was held with respect to all the patients considered for CDS by an attending physician. The main outcome measures were the frequency and characteristics of CDS (patient background, all target symptoms, medications used for sedation, duration, family's satisfaction, and distress). We mailed anonymous questionnaires to bereaved families in August 2011. RESULTS: Of 1581 deceased patients, 22 (1.39%) had received CDS. Physical exhaustion 8 (36.4%), dyspnea 7 (31.8%), and pain 5 (22.7%) were the most frequently mentioned indications. Continuous deep sedation had a duration of less than 1 week in 17 (77.3%). Six patients (0.38%) did not meet the appropriate criteria for CDS according to the MDTC and so did not receive it. Although bereaved families were generally comfortable with the practice of CDS, some expressed a high level of emotional distress. SIGNIFICANCE OF RESULTS: Our results indicate that the prevalence of CDS will be decreased when it is carried out solely for appropriate indications. Continuity of teamwork, good coordination, exchange of information, and communication between the various care providers are essential. A lack of any of these may lead to inadequate assessment, information discrepancies, and unrest.

The patient was a 73-year-old woman. At 63 years of age, she had developed follicular lymphoma that showed a complete response to R-CHOP therapy. Over the subsequent 8 years, she experienced 4 relapses and was administered rituximab monotherapy once, combined rituximab-fludarabine therapy twice, and CHASE-R therapy once, achieving a complete response each time. Before her first therapy, hepatitis B virus (HBV) surface antigen was negative, while hepatitis B surface antibody (anti-HBs) and hepatitis B core antibody were not measured. Later, before her second salvage therapy, anti-HBs was negative, but then changed to positive before her third salvage therapy. HBV-DNA was negative before CHASE-R therapy. At 16 months after completing the CHASE-R therapy, she developed hepatitis and HBV-DNA had changed to positive. Hepatitis did not become fulminant and entecavir administration was effective. It was surmised that HBV had resolved, but she became negative for anti-HBs following the rituximab-containing chemotherapy. Therefore, this is a rare case in which de novo hepatitis developed after the final chemotherapy. The prognosis of patients with de novo hepatitis accompanying treatment of B-cell lymphoma is poor. In those who undergo lymphoma salvage therapy, the risk for and clinical course of HBV reactivation might differ from those of treatment-naïve patients.

Radiation therapy (RTx) has been employed as a curative therapy for prostatic adenocarcinoma. RTx-induced sarcomas (RISs) are rare, late adverse events, representing less than 0.2% of all irradiated patients. RISs are more aggressive tumors than prostatic adenocarcinomas. Herein, we present a case with RTx-induced prostatic leiomyosarcoma after permanent brachytherapy for prostatic adenocarcinoma. A 69-year-old male presented with dysuria and gross hematuria. Six years previously, he had been diagnosed with localized prostate cancer and was treated by permanent brachytherapy. Urethroscopy showed stenosis by a tumor at the prostate. Transurethral prostatectomy was performed for a diagnosis. Based on pathological findings, the diagnosis was leiomyosarcoma of the prostate. He was treated with three cycles of neoadjuvant chemotherapy (CTx) that consisted of doxorubicin and ifosfamide (AI), followed by a prostatocystectomy with intrapelvic lymphadenectomy. The tumor extended from the prostate and infiltrated the bladder wall and serosa with lymphatic and venous invasion. The surgical margin was negative, and no residual prostatic adenocarcinoma was observed. The proportion of necrotic tumor cells by neoadjuvant CTx was around 50%. Subsequently, adjuvant CTx was offered, but the patient chose a follow-up without CTx. Local recurrence and lung metastasis were detected by computed tomography 3 months after the surgery. He was treated again with AI. However, CTx was not effective and he died 6 months after the operation. In conclusion, an effective treatment strategy for prostatic sarcoma should be developed in the near future, although the clinical feature of prostatic sarcoma remains unclear due to its rare incidence.
RESUMEN
Pazopanib, an oral tyrosine kinase inhibitor, is the first molecular-targeted agent approved for the treatment of advanced soft tissue sarcoma(STS). Rhabdomyosarcoma in adults is rare, accounting for less than 3%of all adult STS cases. A 57-year old woman presented with cervical lymphadenopathy. Computed tomography revealed a heterogeneous mass in the retroperitoneum, replacing the entire right kidney. On the basis of the above findings, the patient was diagnosed with alveolar rhabdomyosarcoma. She was first treated with 4 courses of vincristine, actinomycin D, and cyclophosphamide(VAC), which resulted in a partial response. Dose reduction and delay occurred owing to hematological toxicity and febrile neutropenia. As second-line chemotherapy, the patient was administered a single daily dose of 800 mg of pazopanib. Because of an episode of hand-foot syndrome and hepatic impairment, the 800-mg daily dose of pazopanib was reduced to a daily dose of 600 mg, which had to be further reduced to a daily dose of 400 mg owing to fatigue and anorexia. The patient maintained a partial response for a total of 4.3 months when treated with pazopanib. Therefore, this drug may be a new treatment option for patients showing metastatic STS after previous chemotherapy.

Following the introduction of rituximab, the long-term overall survival (OS) rate of advanced-stage follicular lymphoma (FL) cases was expected to improve after the introduction of rituximab: however, there is a lack of large-scale survey data in Asia due to the relatively low incidence of FL. We conducted a retrospective survey to assess the treatment outcomes in patients with newly diagnosed advanced-stage FL in 29 institutions in Hokkaido from January 2001 to December 2010. The total number of patients was 443 (men 47.6%, women 52.4%), with a median age of 55 years (range 20-80 years). Of the cases examined, 42.2% had stage III and 57.8% had stage IV disease. Furthermore, 62.5, 19.7, 9.2, 5.2, and 3.4% had performance statuses of 0, 1, 2, 3, and 4, respectively. The 5-year OS was 91.2%, and no survival plateau was observed. Seventeen patients experienced secondary malignancies (six hematological diseases and 11 solid cancers; 5-year probability, 4.2%). Eighteen patients experienced transformation (5-year probability, 4.5%). The overall survival at 5 years after therapy for transformation was 50%. Before the introduction of rituximab, the 5- to 10-year OS of advanced-stage FL patients in Japan was reported to be about 30-60%. Although these data are limited, improvement in OS has been observed in Japan during the rituximab era.

Higashi Sapporo Hospital is a cancer-specific hospital with palliative care doctors and certified oncologists. During case conferences held twice a week, we routinely evaluate the referred patients. In our case conferences, we selected patients who were referred to our palliative care division from other hospitals, with possible indications for cancer chemotherapies. We reviewed a total of 1215 patients who were referred to our palliative care division. We identified 18 cases as having indications for cancer chemotherapies. Among them, we identified 4 cases as having indications for standard cancer chemotherapies. All 4 patients tolerated the therapies well, responded to chemotherapy, and survived for more than 1 year. Conferences in which oncologists and palliative care doctors can discuss cases frequently and intimately are thought to be important.

More than 30 years have passed since the introduction of the concept of palliative care in cancer care in Japan. However, the majority of the estimated three million cancer patients in Japan do not receive palliative care. Higashi Sapporo Hospital was established in 1983 as a hospital specialized in cancer care. The palliative care unit of our hospital currently consists of 58 beds. Our hospital is one of the largest hospitals in Japan in terms of the number of palliative care beds. On admission to our hospital, all patients are evaluated for palliative care by a multi-disciplinary team and some patients who undergo anticancer therapy receive palliative care when necessary. There are about 65 patients on average (28.3%) who are receiving only palliative care. In 2011, 793 patients died of cancer while admitted at our hospital. This number of cancer deaths accounted for 15% of the 5,324 cancer deaths in Sapporo City in the same year. Our hospital has played an active role according to the philosophy that "palliative cancer care is part of cancer medical care". We here report the current status of the contribution of our hospital to overcoming problems in palliative care and cancer care in Japan.

Peripheral T-cell lymphoma not otherwise specified (PTCL-NOS) comprises a group of heterogeneous lymphomas that do not fit any other identified PTCL-subgroup and show poor prognosis. To clarify clinical aspects of Japanese PTCL-NOS patients, the Hokkaido Hematology Study Group conducted a multicenter retrospective analysis. The median age of the 107 patients (male 65.4 %) was 67 years. The majority (82.4 %) had stage III/IV disease. Following the international prognostic index, 65.7 % were categorized as high intermediate or high risk. Primary chemotherapy was selected in 96 (90 %) patients, 86 of whom received anthracycline regimens. Sixteen patients received high-dose chemotherapy with autologous stem cell transplantation. Forty-eight (52 %) of the 92 evaluable patients achieved complete remission (CR) or CR/unconfirmed after the primary treatment, in which 22 (46 %) relapsed. The estimated 5-year overall survival (OS) of all patients was 35 %. Three independent risk factors (RFs) associated with OS, bulky disease (hazard ratio HR = 5.324; p = 0.019), age >60 years (HR = 3.015; p = 0.025), and platelet count less than 10 × 10(4)/µL (HR = 3.999; p = 0.036), were identified in a multivariate analysis. Using these three RFs, the OS curves were significantly stratified into three risk groups (low risk, 0 RFs, 3-year-OS 72 %; intermediate risk, one RF, 30 %; high risk, two or three RFs, 0 %; p = 0.0005). These findings may provide valuable information for the management of Japanese PTCL-NOS patients.

Invasive fungal infection (IFI) causes morbidity and mortality among patients with hematological malignancies who receive cytotoxic chemotherapy or hematopoietic stem cell transplantation (HSCT). We evaluated the incidence and treatment outcomes of proven and probable IFI in 22 institutions between 2006 and 2008 following the recent European Organization for Research and Treatment of Cancer/Mycosis Study Group (EORTC/MSG) consensus criteria. We analyzed 2,821 patients with hematological malignancies, including 597 who had undergone HSCT; these included patients with acute leukemia (n = 697), myelodysplastic syndrome (n = 284), lymphoma (n = 1465), or multiple myeloma (n = 375). IFIs were diagnosed in 38 (1.3%) patients (18 proven and 20 probable), including 20 patients who underwent HSCT and 18 who received chemotherapy alone; these included patients with aspergillosis (n = 23), candidiasis (n = 6), mucormycosis (n = 6), trichosporonosis (n = 2), and geotrichosis (n = 1). The incidence of IFI was 5.4 % in allogeneic HSCT patients, 0.4 % in autologous HSCT patients, and 0.8 % in patients receiving chemotherapy alone. Eighteen patients with aspergillosis were diagnosed with probable pulmonary IFI as determined by computed tomography scan and positive galactomannan assay. Overall, antifungal targeted therapies resulted in successful outcomes in 60.0 % of patients. IFI-attributable mortality rate was higher in HSCT patients than in those receiving chemotherapy alone, but the difference was not statistically significant.

Pneumothorax associated with chronic graft-versus-host disease (cGVHD) after stem cell transplantation is a rare complication. Autologous blood has been used successfully for pleurodesis, which was less toxic than chemical agents. However, when pneumothorax is resistant to pleurodesis, no other procedure is more effective and conservative. Here, we describe a case of myelodysplastic syndromes complicated with cGVHD-related pneumothorax. His pneumothorax has been resistant to pleurodesis using autologous blood and was treated successfully with fibrin glue sealant. In our limited experience, we believe the best success could be achieved when this method is used to treat persistent pneumothorax with cGVHD.
