In invasive extramammary Pagets disease (EMPD), distant metastases may develop and the condition may become fatal; however, no standardized treatment has been established. Although based on only a few cases, several chemotherapy regimens were reported to be promising. We conducted a multicenter, retrospective study to evaluate the efficacy of docetaxel for metastatic EMPD. We retrospectively collected data on 18 metastatic EMPD patients treated using docetaxel from 1998 to 2012 in 12 institutes in Japan. The following clinical data were collected: tumor response, time to progression, overall survival and adverse effects. Of those, three patients treated combined with S-1, one patient treated with weekly schedule and one patient treated combined with radiotherapy were excluded from the further analysis. All 13 patients received monthly docetaxel as the first-line treatment. The average number of treatment cycles was 9.1. Among the 12 patients with a confirmed response, seven (58%) showed a partial response, three (25%) stable disease and two (17%) progressive disease. The disease control rate (partial response + stable disease) was as high as 83%. The time to progression and median overall survival were 7.1 and 16.6 months, respectively. The 1-year overall survival rate determined by the Kaplan-Meier method was 75.0%. All adverse effects were manageable and no treatment-related deaths were observed. The high disease control rate and overall survival shown by this study suggest that first-line use of docetaxel may be a promising treatment for metastatic EMPD. A prospective clinical trial is required to confirm our results.

Changes in activities of daily living in cancer patients may predict their survival. The Palliative Prognostic Index is a useful tool to evaluate cancer patients, and adding an item about activities of daily living changes might improve its predictive value.To clarify whether adding an item about activities of daily living changes improves the accuracy of Palliative Prognostic Index.Multicenter prospective cohort study.A total of 58 palliative care services in Japan.Patients aged >20years diagnosed with locally extensive or metastatic cancer (including hematological neoplasms) who had been admitted to palliative care units, were receiving care by hospital-based palliative care teams, or were receiving home-based palliative care. Palliative care physicians recorded clinical variables at the first assessment and followed up patients 6months later.A total of 2425 subjects were recruited and 2343 of these had analyzable data. The C-statistic of the original Palliative Prognostic Index was 0.801, and those of modified Palliative Prognostic Indices ranged from 0.793 to 0.805 at 3weeks. For 6-week survival predictions, the C-statistic of the original Palliative Prognostic Index was 0.802, and those of modified Palliative Prognostic Indices ranged from 0.791 to 0.799. The weighted kappa of the original Palliative Prognostic Index was 0.510, and those of modified Palliative Prognostic Indices ranged from 0.484 to 0.508.Adding items about activities of daily living changes to the Palliative Prognostic Index did not improve prognostic value in advanced cancer patients.

Graft-versus-host disease-free relapse-free survival, which is defined as the absence of grade III-IV acute graft-versus-host disease, systemically treated chronic graft-versus-host disease, relapse, and death, is a novel, meaningful composite end point for clinical trials. To characterize risk factors and differences in graft-versus-host disease-free relapse-free survival according to a variety of graft sources, we analyzed 23,302 patients with hematologic malignancy that had a first allogeneic transplantation from 2000 through 2013 using the Japanese national transplant registry database. The 1-year graft-versus-host disease-free relapse-free survival rate was 41% in all patients. The rate was higher after bone marrow transplantation than after peripheral blood stem cell transplantation due to the lower risks of III-IV acute and chronic graft-versus-host disease. The rate was highest after HLA-matched sibling bone marrow transplantation. The rate after single cord blood transplantation was comparable to that after HLA-matched unrelated bone marrow transplantation among patients aged 20 years or under, and was comparable or better than other alternative graft sources among patients aged 21 years or over, due to the low risk of chronic graft-versus-host disease. Other factors associated with better graft-versus-host disease-free relapse-free survival include female patients, antithymocyte globulin prophylaxis (for standard-risk disease), recent years of transplantation, sex combinations other than from a female donor to a male patient, the absence of prior autologous transplantation, myeloablative conditioning, negative cytomegalovirus serostatus, and tacrolimus-based prophylaxis. These results provide important information to guide the choice of graft sources and are benchmarks for future graft-versus-host disease prophylaxis studies.

Endoscopic stenting with a self-expandable metallic stent (SEMS) is a widely accepted procedure for malignant colonic obstruction. The Colonic Stent Safe Procedure Research Group conducted the present prospective feasibility study.Our objectives were to estimate the safety and feasibility of SEMS placement as a bridge to surgery (BTS) for malignant colorectal obstruction. We conducted a prospective, observational, single-arm, multicenter clinical trial from March 2012 to October 2013. Each patient was treated with an uncovered WallFlex enteral colonic stent. Patients were followed up until discharge after surgery.A total of 518 consecutive patients were enrolled in this study. The cohort intended for BTS consisted of 312 patients (61%), and the stent could be released in 305 patients. Technical and clinical success rates were 98 and 92%, respectively. Elective surgery was performed in 297 patients, and emergency surgery was performed in eight patients for the treatment of complications. The overall preoperative complication rate was 7.2%. Major complications, including perforation, occurred in 1.6%, persistent colonic obstruction occurred in 1.0%, and stent migration occurred in 1.3% patients. The median time from SEMS to surgery was 16days. Silent perforations were observed in 1.3%. Open and laparoscopic surgery was performed in 121 and 184 patients, respectively. The tumor could be resected in 297 patients. The primary anastomosis rate was 92%. The rate of anastomotic leakage was 4%, and the overall stoma creation rate was 10%. The median duration of hospitalization following surgery was 12days. Overall postoperative morbidity and mortality rates were 16 and 0.7%, respectively.This largest, multicenter, prospective study demonstrates the feasibility of SEMS placement as a BTS for malignant colorectal obstruction. SEMS serves as a safe and effective BTS with acceptable stoma creation and complication rates in patients with acute malignant colonic obstruction.

Background: Neoadjuvant chemotherapy may improve outcomes in gastric cancer. Tumor responses can be evaluated with RECIST, Japanese Classification of Gastric Carcinoma (JCGC), and histological criteria. These approaches have not yet been compared. Methods: We analyzed two phase II trials of neoadjuvant chemotherapy using S-1 plus cisplatin. JCOG0210 included patients with linitis plastica and large ulcero-invasive tumors, whereas JCOG0405 comprised those with para-aortic or bulky lymph node metastases. Radiologic evaluations were conducted using RECIST in JCOG0405 and JCGC criteria in JCOG0210, because the latter included many patients without measurable lesions. A histological responder was defined as a patient in whom one third or more of the tumor was affected. The hazard ratios (HR) for death between responders and non-responders and response rate differences between short- and long-term survivors were estimated. Results: In JCOG0210 (n = 49), HR was 0.54 in JCGC responders (P = 0.059) and 0.40 in histological responders (P = 0.005). The difference in response rates between short- and long-term survivors using histological criteria (34 %, P = 0.023) was greater than that using JCGC criteria (24 %, P = 0.15). In JCOG0405 (n = 51), HR was 0.67 in RECIST responders (P = 0.35) and 0.39 in histological responders (P = 0.030). In short- and long-term survivors, respectively, RECIST response rates were 62 and 67 % (P = 0.77), whereas histological response rates were 33 and 63 % (P = 0.048). Conclusions: Histological criteria showed higher response assessment validity than RECIST or JCGC criteria and yielded the best surrogate endpoint for overall survival. © 2013 The International Gastric Cancer Association and The Japanese Gastric Cancer Association.

Human immunodeficiency virus (HIV) induces acquired immunodeficiency syndrome (AIDS) in humans. Neurological complications occur frequently in patients with AIDS. About 20 to 40% of all these patients develop neurological symptoms, and in about 10% of AIDS patients, the onset of the disease is characterized by neurological symptoms. These may be related to primary HIV infection or to any of a large number of opportunistic viral and non-viral infections. HIV itself induces acute HIV aseptic meningitis, HIV-1-associated neurocognitive disorder (HAND), HIV distal sensory polyneuropathy, and HIV vacuolar myelopathy. The opportunistic neurological infections are cytomegalovirus encephalitis and polyradiculomyelitis, toxoplasmosis encephalitis, cryptococcal meningitis, and progressive multifocal leukoencephalopathy. Other neurological complications are primary central nervous system lymphoma, cerebral vascular disease (CVD), and nucleoside neuropathy (NN). Among these complications, HAND, CVD, and NN are expected to have an increaced incidence in the future, they may be more important complications in HIV infection.

We report herein the case of a 37-year-old man who developed probable progressive multifocal leukoencephalopathy (PML) following an umbilical cord blood transplant. The patient showed favorable clinical, neuroradiological and virological responses after treatment with mefloquine, an anti-malarial drug. Mefloquine may offer some benefits as a treatment for PML in patients with or without human immunodeficiency virus type-1 infection. This report highlights the need to gather sufficient data to confirm the efficacy of mefloquine against this devastating viral disease of the central nervous system. © The Japanese Society of Internal Medicine.

We report multidisciplinary treatment of 3 patients with lymph node recurrence after curative gastrectomy. Case 1: A 71- year-old woman had a history of distal gastrectomy with D2 lymphadenectomy for the treatment of advanced gastric cancer. Para-aortic lymph node metastasis was observed 36 months after surgery. Complete response( CR) was achieved after concurrent chemoradiotherapy with S-1 plus radiation. Case 2: A 51-year-old man had a history of total gastrectomy with D2 lymphadenectomy for the treatment of advanced gastric cancer. Right cervical lymph node metastasis was observed 48 months after surgery. CR was achieved after concurrent chemoradiotherapy with S-1 plus radiation. Case 3: A 68-year-old man had a history of distal gastrectomy with D2 lymphadenectomy followed by neoadjuvant chemotherapy for the treatment of advanced gastric cancer. CR was achieved after sequential treatment with irinotecan( CPT-11) plus cisplatin( CDDP), radiation, and 5-fluorouraci(l 5-FU) plus Leucovorin therapy for lymph node recurrence near the head of the pancreas. These cases suggest that the combination of systemic chemotherapy and local radiation therapy might be effective for the treatment of lymph node recurrence in patients with gastric cancer.

Although many studies have already shown that lymph node metastasis is one of the major prognostic factors for cervical cancer, the therapeutic significance of para-aortic lymphadenectomy for the surgical treatment of cervical cancer remains controversial.A total of 308 patients diagnosed with stage IB2, IIA2, or IIB cervical cancer and treated with radical hysterectomy were retrospectively investigated to assess the incidence of para-aortic lymph node metastasis and the clinicopathological factors linked to cervical cancer prognosis.Para-aortic lymph node metastases were pathologically confirmed in 13 of the 136 patients (9.6 %) who underwent para-aortic lymphadenectomy. The incidence of para-aortic lymph node metastasis was significantly higher in the patients who had common iliac lymph node metastases (odds ratio 31.5, p < 0.001) according to logistic regression analysis. Common iliac lymph node metastasis was related to risk of recurrence (hazard ratio 2.43, p = 0.003) and death (hazard ratio 2.62, p = 0.007) in Cox regression analysis. Kaplan-Meier analysis and Cox regression analysis showed that para-aortic lymphadenectomy did not have a positive impact on survival in 308 patients or 140 pN1 patients, but para-aortic lymphadenectomy was related to better overall survival with a marginal trend toward significance (p = 0.053) in 30 patients with common iliac lymph node metastasis.Indication for para-aortic lymphadenectomy in the surgical treatment of stage IB2, IIA2, or IIB cervical cancer needs to be individualized. Patients with common iliac lymph node metastasis are possible candidates, and a prospective study is needed to clarify this issue.
