Background: It is a well-known fact that the prevalence of malignancy increases year by year. In addition, other malignancies may be found in the systemic screening before treatment or after several therapy during observation. Malignant lymphoma is often the most number of patients. We reviewed the complication with lung cancer that was a poor prognosis. We look for possibility of the prognosis improvement by determining a characteristic. Methods: In 290 cases multiple cancer including hematological malignancy in our department, we examined 20 cases that including lung cancer & malignant lymphoma. Reviewed the following is gender, age, outbreak style, strategy of therapy, clinical income, and overall survival. Diagnostic criteria of multiple cancer is according to Warren&Gates. It was distinguish synchronous and metachronous that synchronous double cancer diagnosed interval of 6 months. Results: The subjects were 20 patients, median age was 70 years. Synchronous cancer was found in 5 patients and metachronous in 15 patients. Malignant lymphoma was non-Hodgkin`s lymphoma in 11 patients, Hodgkin`s lymphomain 2 patients and lymphoma- stage mycosis fungoides in 1patient. Acute myelogeneous leukemia 3 cases, myelodysplastic syndrome 3 cases. All of the patients with ML underwent chemotherapy (CTx) and 8 and 4 of them achieved completeand partial remission, respectively, while 2cases had progressive disease. In 20 cases with LC, operation (Ope) alone was conducted in 6 cases, Ope+ adjuvant therapy in 3 cases, radiation therapy (RTx) in 1case, RTx + CTx in 1case, and CTx alone in 7 cases, non therapy 2 cases. The median survival was 11 months. Conclusions: For metachronous type, there is chance to fi nd second cancer, if they observed long time. I think that we must understand he has or will have another cancer. Prognosis improvement of the advanced lung cancer is expected.

Background: Colon cancer accounts for number of cases, a superior of the cause of death like gastric cancer, lung cancer. Wereport aggregates the multiple neoplasms including hematological malignancy and colon cancer. Methods: In the case that hematologic malignancy was diagnosed in our hospital by 1988 from 2013, The multiple cancer including colon cancer and the hematologic malignancy was 45 cases. So we reviewed and reported. Results: All cases are 45 cases, including female 14 cases, male 31cases, synchronous type 15 cases, metechronous type 30 cases. Multiple neoplasms consist of double cancer 33 cases, triple cancer 11 cases, quadrop cancer 1case. The median interval period in double cancer is 58 months. Hematological malignancy consist of non-Hodgkin`s lymphoma 24 cases, Hodgkin`s lymphoma 1 case, myelodysplastic syndrome 6 cases, chronic myelogeneou leukemia 3 cases, multiple myeloma 5 cases, macroglobrinemia 2 cases, acute lymphoblastic leukemia 3 cases, acute myelogeneous leukemia 2 case. Chronic lymphocytic leukemia 1 case. The sites of colon cancer studied 41 cases and results were that ascending colon 7cases, transverous colon 3cases, descending colon 2cases, sigmoid colon 9cases, rectum 8 cases. In a double cancer, 12 cases were preceding colon cancer and 9 cases were preceding hematological malignancy, an interval of the colon cancer precedence cases, the median time was 83M, hematological malignancy precedence cases was 42M. Median survival time is 15M, about cause of death, 21 cases still alive and 24 cases are dead. In 24 cases, hematological malignancy 17 cases, colon cancer 7 cases. Conclusions: In the case of hematological malignancy precedence case, 4 of 9 colon cancer occurred within three years. We should take attention about incidence of other malignancies, particularly those that occur from gastrointestinal tract and serious observation about distant metastasis site, such as liver and lung.

Background: Chemotherapy of the elderly person was common practice. Clinical outcome is force to equal an adult. However, a patient 90 years or older has a high risk of chemotherapy. We report our experience with two patients of malignant lymphoma 90 years or older. Methods: In periods from 2003 to 2013, patients whom malignant lymphoma was diagnosed in our hospital, we extracted a case 90 years or older. We reviewed gender, clinical stage, chemotherapy, dosage, clinical outcome, and prognosis. Results: Case 1: 91-year-old male, fi rst manifestation was systemic lymphadenopathy, Sufferings from dyspnea, he became the hospitalization. Pleural effusion was revealed, after lymph node biopsy, he was diagnosed non-Hodgkin`s lymphoma diffuse large B cell (NHL DLBCL). We performed chemotherapy by his strong wish. After 3 course of R-CHOP (dosage 50%), he achieved partial remission and was able to return to the house. He died after a diagnosis in 13 months. Case 2: 90-year-old female, fi rst manifestation was dysfunction of artifi cial denture, she had a checkup in dentistry. At the time dentist discovered a mass lesion and performed biopsy. Diagnosis was NHL DLBCL, and she was referred and had performed chemotherapy our hospital. After 6 course of R-CHOP (dosage 65%), she achieved complete remission and he still alive. Conclusions: It is got enough cinical outcome from even a case 90 years or older bychemotherapy. However, drug reduction criteria are not established that are indispensable for safe chemot

Background: The myelodysplastic syndrome is blood stem cell disease and in many cases, have cytogenetic abnormality. And myelodysplastic syndrome has characteristic that there is defi ection in elderly. But progress of therapy and supporting therapy improved a prognosis. The possibility that a survivor had the second malignancy rise. we reviewed multiple neoplasms including the myelodysplastic syndrome and we report. Methods: In the case that hematologic malignancy was diagnosed in our hospital from 1988 to 2012, we intended for double cancer 271 cases including hematological malignancy. We reviewed 43 multiple neoplasms including the myelodysplastic syndrome. The examination factors are type of the hematological malignancy, treatment, gender, interval with the second cancer. Results: All cases are 43 cases, including male 29 cases, female 14 cases, type of multiple neoplasms, double 40 cases, triple 3 cases, kind of multiple neoplasms, metachronous 31 cases, synchronous 12 cases. The malignancies to constitute multiple neoplasms with myelodysplastic syndrome are gastric cancer 11 cases, esophangeal carcinoma 5 cases, breasr cancer 3 case, multiple myeloma 6 cases, non-Hodgkin`s lymphoma 3 cases, colon cancer 5 cases, lung cancer 4 cases, renal carcinoma 2 cases, urinary bladder carcinoma 2 cases, prostate carcinoma 1 case, thyroid cancer 1 case, pharyngeal cancer 1 case, laryngeal cancer 1 case, angiosarcoma 1 case. On the other hand, acute myelogeneous leukemia, therapy-related leukemia are11 cases, de novo myelodysplastic syndrome 32 cases. Conclusions: The survivors by the fi rst cancer therapy are paid attention to therapy- related myelodysplastic syndrome.

Background: Malignant lymphoma(ML) is the ninth place cause of death in Japan and chemotherapy(CTx) is fi rst choice. Side effect of CTx, rituximab, reactivation of the Hepatitis B type virous(HBV) is serious problem. We reviewed the situation of the HBV infection check of patients that was performed CTx. Methods: We intended for patient which ML was diagnosed in our hospital from January 2003 to December, 2012. The pretreatment HBV check factor is hepatitis B surface antigen(HBsAg), hepatitis B surface antibody(anti-HBs), antihepatitis B core antibody(anti-HBc). When either anti-HBs or anti-HBc is positive, we measure viral amount by HBV-DNA Taqman. In the case of HBV check is imcomplete, additional HBV check followed as much as possible. We reviewed positive rate of HBsAg, anti-HBs, anti-HBc. Also we investigated HBV reactivation rate of R+CTx. Results: All cases were 446 cases, about type of malignant lymphoma, Hodgkin`s lymphoma(HL) 39 cases, non-Hodgkin`s lymphoma(NHL) 401 cases, Adult T cell Lymphoma( ATL) 6 cases. Among 446 patients, 411 cases received CTx or CTx+radiation therapy(RTx). HBsAg was examined in all cases, anti-HBs, anti-HBc was 351 cases, 261 cases respectively. The case searched three factors before CTx was 150 cases. 30 cases were searched HBV-DNA Taqman that indicated anti-HBs and/or anti-HBc were positive. In theses cases, treatment needed situation were 5 cases. These 5 cases treated by entecavir and after 2 weeks, CTx performed. The case that already given an antiviral drug with HBsAg positive for treatment was 4 cases. 107 cases were searched anti-HBs, anti-HBc or either after CTx. 2 cases was revealed to have needed the administration of antiviral drug. HBV reactivation rate was 0%. Conclusions: Only 2 cases needed therapy for HBV infection that were revealed after CTx. We do check in all cases and try for safe chemotherapy especially rituximab including regimen.

Background: Though oral infection represented by caries and periodontal disease is the infectious disease that is thought with life-style related diseases generally. Including hematological malignancy, the infectious disease research before taking anticancer drug treatment is important. A potential infectious disease may bring about a fatal infectious disease for bone marrow suppression period. We report it this time about an oral surgery area as a search before treatment of the malignant lymphoma. Methods: In eight years from 2003 to 2012, we intended for a case in newly diagosed malignant lymphoma in our hospital. We reviewed having consultation or not of the oral surgery, treatment contents, having exodontia or not. Results: Among 383 patients, the oral surgery consultation was 271 cases, male female ration was 150/121. T, and the age median was 67years. It was 154 cases that it was judged that treatment was necessary. The case performed exodontia was 53 cases. Among 53 patients, 33 cases were progression stages. Conclusions: With the onset of febril neutropenia, the infectious disease that is not seen occurs with the normal immune status. An oral cavity lesion is a neighborhood of the central nerve system and is in very danger. Fortunately, there was not the case of death for the infection of the oral cavity lesion. However, malignant neoplasms patients has much dentistry treatment, and the exodontia number accounts for the majority, too.

Background: In Japan, ML is hematological malignancies with much number of cases. non-Hodgkin`s lymphoma(NHL) is more than 90%. There is extremely little number of patients Hodgkin`s lymphoma(HL). In Europe, the rarion between NHL and HL, is almost half and half. So we paid attention to HL and examined. Methods: We intended for patient which ML was diagnosed in our hospital from January 2003 to December, 2012. We studied and reported 38 cases about age, gender, pathological fi ndings, therapy, median survival time, 5 years survival rate. Survival was measured from the diagnosis of multiple cancer to time of death or last contact. Results: All cases were 38 cases, gender ration was male 23 cases, female 16 cases. Median age was 45 years, pathological fi ndings, L-D 1 case, L-P 1 case, L-R 6 cases, MC 15 cases, PHL 1 case, NS 14 cases. About clinical stage, I was 5 cases, II was 15 cases, III was 10 cases, IV was 7 cases. Adult patients were 25 cases, elderly patients were 13 cases. About therapy, more than 65 years old that assumed Bleomycine skipped. ABVD therapy performed 26 cases, ABVD therapy + RTx 1 case, AVD therapy 8 cases, C-MOPP therapy 3 cases. Median survival time was 84 months, and 5 years survival rate was 79. 6%. About age, less than 60 years group did not reach median survival time, median survival time of more than 60 years group was 76 months. There is no signifi cant difference between 2 group. 29 cases were survivor and death cases were 9 cases. Cause of death, 8 cases due to original disease, 1 case another reason( because of lung cancer). Conclusions: HL is good prognosis disease in hematological malignancies, but in more than 60 years patients, there is many problem.

Poster Session : PS 0335 ; Hematology : Study of Non-Hodgkin`s Lymphoma Diffuse Large B Cell Cases That are Treated without Rituximab

( Kazuhiko Natori ),( Daisuke Nagase ),( Susumu Ishihara ),( Akiko Sakai ),( Motohiro Kato ),( Yasunobu Kuraishi ),( Kazuho Arai ),( Haruka Izumi ) 대한내과학회 2014 대한내과학회 추계학술대회 Vol.2014 No.1

Background: The strategy of non-Hodgkin`s lymphoma changed dramatiscally, especially in B cell type by rituximab. The pathological fi ndings which showed immunochemical stain CD20 positive cases, rituximab is effective agent about. Some cases did not treat without rituximab several reasons. Methods: From 2003 to 2012, 9 years, we intended for 446 patients whom malignant lymphoma was diagnosed in detail by histopathology. Clinical stage is determinded by Ann Aobor classifi cation. We investigate the cases who do not treat without rituximab about the reason, age, clinical stage, therapy and prognosis. Results: All cases are 69 cases, about gender, male 42 cases, female 27 cases, median age is 71 years ranged 22-89 years. Perfomance Status at diagnosis, 0 grade 20 cases, 1grade 17 cases, 2grade 4 cases, 3grade 10 cases, 4grade 18 cases. About clinical stage by Ann Aobor classifi cation, I is 14 cases that included L-I(Lugano classifi cation), II is 5 cases, III is 9 cases, IV is 41 cases. Strategy of therapy, best supporting care 17 cases, aim to cure 42 case, palliative 11 cases. The reason without rituximab, bestsupporting care 18 cases, another standard therapy 13 cases, CD20 negative 3 cases, Hepatitis B virus active infection 6 cases, Hepatitis C virus active infection 2 cases, palliative therapy 12 cases, infusion reaction 9 cases, much tumor burden 2 cases, avoiding gastrointestinal perforation 2 cases, leukemic state 1 case. Median survival time is 12 months ranged 1-111 months. Conclusions: Rituximab is remarkably improved prognosis about non-Hodgkin`s lymphoma.

Poster Session : PS 0334 ; Hematology : Retrospective Study of the Follicular Lymphoma

( Kazuhiko Natori ),( Daisuke Nagase ),( Susumu Ishihara ),( Akiko Sakai ),( Motohiro Kato ),( Yasunobu Kuraishi ),( Kazuho Arai ),( Haruka Izumi ) 대한내과학회 2014 대한내과학회 추계학술대회 Vol.2014 No.1

Background: The malignant lymphoma is the ninth place cause of death in Japan. A ratio of non-Hodgkin`s lymphoma(NHL) is overwhelmingly big in malignant lymphoma in Japan. Follicular lymphoma was rather small ratio, not only Asian area but also European area. So we reviewed and report our experience of follicular lymphoma patients. Methods: In periods from 2003 to 2012, 446 patients whom malignant lymphoma was diagnosed in our hospital, we extracted follicular lymphoma. We reviewed gender, clinical stage, chemotherapy, clinical outcome, and prognosis. Results: During studied periods, eligible data for investigation was 58 cases, including female 36, male 22, median age was 62 years. About clinical stage, I 2 cases, II 8 cases, III 14 cases, IV 34 cases, advanced stage was dominant. In treatment strategy, aim to cure standard therapy that rituximab + CHOP or rituximab + CHOP like regimen performed 51 cases, RCHOP regimen 39 cases, RCHO regimen 9 cases, RCHOP like regimen 1case, RCVP regimen3 cases, radiation therapy alone 3 cases. About median survival time dose not reach, 5 years overall survival rate is 85. 8%. Compared between up to stageIII versus IV, each group dose not reach median survival time, and there is not signifi cant difference about survival. 5 years survival rate are 83. 2%, 88. 8% respectively. Cause of death, 7 cases were death, consist of cause of death, 5 cases were due to original disease, 1 case due to heart attack, 1 case due to gastric cancer. Conclusions: The clinical outcome of follicular lymphoma improved by rituximab. But some cases do not effect chemotherapy and not reach complete remission, especially in elderly, organs disfunction are trouble about anti-cancer agent dosage, so insuffi - cient therapy performed. We must manage such cases using new strategy.
