A case of advanced intrahepatic cholangiocarcinoma successfully treated with chemosensitivity test-guided systemic chemotherapy

Intrahepatic cholangiocarcinoma (ICC) is a relatively rare and highly fatal neoplasm that arises from the biliary epithelium. Prognosis is generally poor and survival is limited to a few months. Here we present a case of advanced ICC successfully treated by chemosensitivity test-guided systemic chemotherapy combining S-1 and cisplatin (CDDP). A 65-year-old woman with a liver tumor was referred to our hospital on November 21, 2007. Abdominal ultrasonography and computed tomography (CT) showed low-density masses of 50 and 15 mm in diameter, respectively in segment Ⅷ of the liver and in the enlarged lymph node in the para-aorta. Ultrasonography-guided fine needle biopsy diagnosed the tumors as ICC. Since the patient was inoperable for lymph node metastasis, she underwent systemic chemotherapy with gemcitabine. Six months after initiation of chemotherapy, CT revealed ICC progression in the liver and pleural dissemination with pleural effusion. The patient was admitted to our hospital for anticancer drug sensitivity testing on June 9, 2008. Based on the sensitivity test results, we elected to administer systemic chemotherapy combining S-1 and CDDP. Two months into the second chemotherapy treatment, CT revealed a reduction of the tumors in the liver and lymph node and a decrease in pleural effusion.After eight cycles of the second chemotherapy, 17 mo after ICC diagnosis, she is alive and well with no sign of recurrence. We conclude that chemosensitivity testing may effectively determine the appropriate chemotherapy regimen for advanced ICC.     

A case of malignant peritoneal mesothelioma successfully treated with systemic chemothrapy

A 64-year-old man with a 2-month history of abdominal distension was admitted for transient cerebral ischemic attack. A CT scan revealed massive ascites. Laparoscopy showed multiple whitish nodules on the visceral peritoneum and the omentum. Peritoneal biopsy revealed tumor cells consistent with malignant peritoneal mesothelioma (MPeM). Pemetrexed in combination with cisplatin was administered because it has been reported to be active in patients with MPeM. However his disease progressed. As second-line therapy paclitaxel was tried which yielded a complete response (CR). Eighteen months later he developed abdominal pain of the right upper region where a CT scan showed a mass with surrounding inflammation. As third-line therapy, gemcitabine was administered and again resulted in a CR. He is alive at 3 years from first presenting. Searches for case studies published in medical journals on MPeM were carried out, and 59 cases were analyzed in comparison with this case.     

A case of advanced hepatocellular carcinoma with lung, brain and lymph node metastases recurred 8 years after hepatectomy successfully treated by operation, radiation and systemic chemotherapy using S-1/CDDP

A 30-year-old man underwent a left lobectomy and S5/6 partial hepatectomy in August 2001 for hepatocellular carcinoma (HCC). A lung tumor was detected by positron emission tomography (PET-CT) 8 years after the surgery. In May 2010, he received pulmonary tumor resection and the histopathological findings revealed metastasis of HCC. However a metastatic brain tumor was detected by computed tomography (CT) in September 2010, therefore surgery and radiation therapy were subsequently performed. Thereafter, metastatic hilar lymph node appeared in December 2010, therefore we performed systemic chemotherapy using S-1/cisplatin combined with radiation therapy for the metastatic tumor. The tumor was markedly decreased and no shadow was detected by PET-CT. He has been followed up in the outpatient clinic with no recurrence.     

A case of Evans syndrome combined with systemic lupus erythematosus successfully treated with rituximab

Evans syndrome is a rare autoimmune disorder with unknown aetiology. Although corticosteroids and/or intravenous immunoglobulin (IVIG) are commonly used in its treatment, no standard strategy has been established. We report here a 44-year-old male with refractory Evans syndrome combined with systemic lupus erythematosus (SLE) who responded well to rituximab. He was admitted to our hospital with severe bleeding caused by worsening of Evans syndrome. Despite treatment with a high-dose corticosteroid and IVIG, his thrombocytopaenia and haemolytic anaemia did not improve. We started rituximab at a dose of 375 mg/m(2) once a week for a total of two doses. There was significant improvement in his thrombocytopaenia and anaemia 1 month after administration of rituximab. Although the total immunoglobulin G (IgG) level did not change, the titres of platelet-associated IgG (PA-IgG) and of an indirect antiglobulin test (IAT) decreased under the treatment with rituximab. It is suggested that rituximab would be a powerful candidate in the treatment of refractory Evans syndrome by depleting abnormal clone-producing autoantibody.     

A case of alpha-fetoprotein-producing gastric cancer with hepatic metastasis successfully treated with combination chemotherapy

The patient was a 79-year-old woman. We became introduction consultation than a nearby doctor in alpha-fetoprotein(AFP)high level. Abdominal ultrasonography showed 30mm great tumor in liver lateral segment area and gastric fiber showed type2 tumor which is AFP producing gastric cancer. On admission AFP level is high(403ng/ml). Multiple liver metastases were noted it by abdominal angiography. We started FLAP(5-fluorouracil, leucovorin, etoposide, cisplatin)combination chemotherapy by a diagnosis of AFP producing gastric cancer StageIV. It is reduction of a liver tumor after one course, and the stomach lesion almost disappeared after three courses end points.     

A case of systemic amyloidosis treated by chemotherapy with autologous peripheral blood stem cell transplantation]

A 67-year-old woman was admitted to our hospital because of breathlessness. Systemic amyloidosis had been diagnosed 5 years previously. Her chest X-ray film showed multiple nodules in both lung fields. Chest computed tomography (CT) revealed some of the nodules had calcifications. Bronchoscopy demonstrated amyloid deposits in the bronchial walls. The serum titer of anti-SS-A antibody was high. Results of both the Schirmer Test and the Rose-Bengal Test were positive. The final diagnosis was systemic amyloidosis with Sj?gren's syndrome. She was treated by chemotherapy using high dose melphalan with autologous peripheral blood stem cell transplantation (PBSCT). It was obvious that her chest X-ray film findings and bronchoscopic findings had improved 9 months after high dose chemotherapy with PBSCT. The disappearance of M protein and improvement of thirst, a symptom of Sj?gren's syndrome, were also observed.     

Inflammatory myofibroblastic tumor successfully treated with chemotherapy and nonsteroidals: A case report

Inflammatory myofibroblastic tumor (IMT) occurring at retroperitoneal sites has rarely been reported. We report the case of a previously well 14-year-old girl with no history of abdominal disease whose past medical history and family tumor history were unremarkable. She complained of intermittent abdominal pain for one month. An abdominal mass was found on physical examination and abdominal contrast-enhanced computed tomography (CT) showed a hypodense soft mass, the size and location of which suggested a well delineated retroperitoneal tumor surrounding the superior mesenteric vessels measuring 3.3 cm × 4.5 cm × 4.5 cm with enlarged lymph nodes. The patient underwent an exploratory laparotomy followed by biopsy and was subsequently diagnosed with retroperitoneal IMT. She was successfully treated with postoperative chemotherapy and oral diclofenac sodium. Following completion of therapy the mass was no longer palpable and no longer visible on CT scanning. The use of methotrexate and cisplatin for aggressive myofibroblastic tumors is also reviewed.     

A case of Crohn's disease successfully treated with infliximab without steroid]

A 39-year-old man diagnosed as Crohn's disease suffered steroid induced psycosis during treatment for Crohn's disease on July 2001. He was admitted on May 2002, because of progressing high fever, abdominal pain and diarrhea. He was treated with infriximab (5mg/kg) together with mesalazine without steroid. The treatment induced rapid improvement of systematic symptoms together with laboratory data and colonoscopic findings. He kept remission for more than 10 months after a single administration of infliximab (5mg/kg). The case is suggestive of wider indication of infliximab for Crohn' s disease.     

A case of refractory Wegener's granulomatosis successfully treated with high-dose methotrexate]

We report a case of generalized Wegener's granulomatosis (WG) successfully treated with high-dose methotrexate (MTX) and predonisolone (PSL). A 35 year-old men had complaints of auditory disturbance and nasal hemorrhage. Diagnosis of WG was made based on positive proteinase-3 anti-neutrophil cytoplasmic antibody (PR3-ANCA), lung nodules, and focal necrotizing glomerulonephritis revealed by renal biopsy. Treatment with cyclophosphamide (CY) and PSL for 3 months was ineffective for the lung nodules. Then, CY was changed to high dose MTX (18mg/week), and his lung lesions improved. In Japan, it is unusual to treat WG with high-dose MTX, but this treatment may be useful in CY-resistant WG.     

A case of pneumonitis induced by CDDP and 5-FU]

A 60-year-old man was admitted to our Department of Urology because of the lack of effectiveness of CHOP therapy for a retroperitoneal tumor. The tumor was finally diagnosed as poorly differentiated adenocarcinoma by CT-guided needle biopsy. He received combination chemotherapy with CDDP and 5-FU. After the end of this therapy, he noticed dyspnea and cough. He was referred to our department and a diagnosis of drug-induced pneumonitis was made because of diffuse shadows in bilateral lung fields, 67Ga citrate scintigraphy, his clinical course and histological examination of TBLB specimens. He received steroid therapy including methylprednisolone pulse therapy, after which his symptoms and abnormal chest findings improved. Although lymphocyte stimulation tests by CPA, DXR, VCR, CDDP and 5-FU were negative, it was suggested that CPA primed and 5-FU induced the pneumonitis in this patient judging from past literatures.     

A case of primary cardiac B cell lymphoma associated with ventricular tachycardia, successfully treated with systemic chemotherapy and radiotherapy: a long-term survival case

We experienced a long-term survival case of primary cardiac lymphoma (PCL) demonstrating ventricular tachycardia (VT) as an initial sign, which was related to localized myocardial damage by lymphoma cells. A 70-year-old woman with sustained VT was admitted to the Kofu Municipal Hospital. VT ceased with the administration of disopyramide intravenously. The origin of the VT was the free wall of the right ventricular outflow tract (RVOT) as observed by electrocardiography on admission. A solitary mass in the free wall of the RVOT was found by echocardiography, chest computed tomographic scanning and magnetic resonance imaging. There was no evidence of extracardiac involvement. The patient was histologically diagnosed as PCL by endomyocardial biopsy. Chemotherapy started immediately after the diagnosis and the mass showed a marked reduction in size. After 8 cycles of chemotherapy, radiotherapy was performed. Pericardial thickness in the free wall of the RVOT developed without severe side effects. Complete remission has been maintained for 30 months after the initial diagnosis, and no recurrence and arrhythmias have been detected during the follow-up period. It was demonstrated that rapid diagnosis and chemotherapy followed by radiotherapy for PCL achieved better survival.     

A case of dermatomyositis complicated with pneumomediastinum that was successfully treated with cyclosporin A]

We reported the case of a 39-year-old man with dermatomyositis (DM) complicated with subcutaneous emphysema and pneumomediastinum during steroid therapy. The patient had complained of muscle weakness, dyspnea and skin eruption on his anterior chest wall 6 months prior to admission. He was diagnosed as having DM on the basis of an elevation in myogenic enzymes, myogenic changes in electromyography, a skin biopsy and a muscle biopsy. Chest roentgenogram revealed interstitial pneumonia (IP) in the lower lobes of the lungs. The administration of prednisolone (60 mg/day) was initiated, which resulted in improvement of DM. Fifteen days after the initiation of the steroid therapy, the patient developed subcutaneous emphysema and pneumomediastinum. Additional administration of cyclosporin A (CsA) enabled us to rapidly taper the dose of prednisolone without aggravating the diseases. Several reports have shown that vasculitis might be involved in the pathogenesis of pneumomediastinum in DM patients. Infection and tissue fragility due to steroid therapy worsen the outcome of those patients. CsA therapy may improve the outcome through the anti-vasculitic- and steroid sparing-effects.
