Abstract
Background Oral mucositis (OM) is an unpleasant adverse event in patients receiving chemotherapy. A prospective feasibility study showed that elemental diet (ED), an oral supplement that does not require digestion, may prevent OM. Based on this, we established a central review system for oral cavity assessment by dental oncology specialists blinded to background data. We used this system to elucidate the preventive effect of an ED against OM in patients with esophageal cancer receiving docetaxel, cisplatin, and 5-fluorouracil (DCF) therapy. Patients and methods In this phase III, multicenter, parallel-group, controlled trial, patients consuming a normal diet orally were randomly assigned (1 : 1) to receive two cycles of DCF with (group A) or without (group B) an ED (Elental® 160 g/day). We assessed the incidence of grade ≥2 OM evaluated by two reviewers, changes in body weight, prealbumin, C-reactive protein, and DCF completion rate based on ED compliance. Results Of the 117 patients randomly assigned to treatment, four failed to start treatment and were excluded from the primary analysis; thus, groups A and B comprised 55 and 58 patients, respectively. There were no significant differences in background characteristics. Grade ≥2 OM was observed in eight (15%) and 20 (34%) patients in groups A and B, respectively (P = 0.0141). Changes in body weight and prealbumin during the two DCF cycles were significantly higher in group A than B (P = 0.0022 and 0.0203, respectively). During the first cycle, changes in C-reactive protein were significantly lower in group A than B (P = 0.0338). In group A (receiving ED), the DCF completion rate was 100% in patients with 100% ED compliance and 70% in patients failing ED completion (P = 0.0046). Conclusions The study findings demonstrate that an ED can prevent OM in patients with esophageal cancer receiving chemotherapy. Patients receiving docetaxel, cisplatin, and 5-fluorouracil (DCF) chemotherapy commonly develop oral mucositis (OM). An elemental diet (ED) was able to prevent OM in patients with esophageal cancer receiving DCF. Grade ≥2 OM was observed in 15% of patients receiving the ED versus 34% of those not receiving the ED (P = 0.0141). Body weight was maintained in the ED group, and hematologic toxicities were lower, compared with the non-ED group. The DCF completion rate significantly correlated with ED compliance (P = 0.0046).

Abstract
Definitive chemoradiotherapy (CRT) with docetaxel (DOC) and 5-fluorouracil (5-FU) is a unique regimen for esophageal cancer. In this prospective phase II study, antitumor effect and safety of CRT using DOC and 5-FU for inoperable locally advanced esophageal cancer were evaluated. DOC 7.5 mg/m2 was infused on days 1, 8, 22, and 29. 5-FU 250 mg/m2 /day was infused continuously on days 1-5, 8-12, 15-19, 22-26, 29-33, 36-40, and 43-45. Radiotherapy was given to 66 Gy in 33 fractions. Eleven patients with thoracic and five with cervical esophageal cancer were eligible. All patients had esophageal squamous cell carcinoma (ESCC). The response rate was 94%, with complete response in five patients (31%) and partial response in 10 (63%). Hematologic toxicity was mild; only one patient (6%) had Grade 1 leukopenia. Nonhematologic Grade 3 or higher adverse events were esophagitis (31%), anorexia (6%), and esophago-bronchial fistula (6%). No treatment-related deaths occurred. The median time to progression was 20 months and overall 3-year and 5-year survival were 44% and 31%, respectively. Definitive CRT using DOC and 5-FU could be performed safely, and it demonstrated a favorable antitumor effect for ESCC. This regimen might be indicated in patients in whom it is desirable to avoid myelosuppression and progression of renal impairment.

Abstract
We compared the surgical outcomes between 114 patients who did not receive neoadjuvant therapy (group 1) and 92 others who received neoadjuvant chemoradiotherapy (nCRT) (group 2), and assessed the preoperative and surgical factors that influence postoperative morbidity to determine the impact of nCRT on morbidity and mortality after esophagectomy via cervical, right transthoracic, and abdominal approaches. The overall postoperative morbidity rates were 44.7% and 55.4% in groups 1 and 2, respectively (P = 0.13). Rates of anastomotic leak (8.8% vs. 16.3%; P = 0.10), pneumonia (9.6% vs. 13.0%; P = 0.44), recurrent nerve palsy (15.8% vs. 10.9%; P = 0.31), and all other complications did not significantly differ between the groups. Multivariable analysis revealed cervical lymph node dissection (odds ratio [OR], 1.97; 95% confidence interval [CI], 1.01-3.84; P = 0.047) as the sole independent covariate for overall morbidity. Furthermore, a history of cardiovascular disease (OR, 2.90; 95% CI, 1.03-8.24; P = 0.045), the retrosternal reconstruction route (OR, 15.15; 95% CI, 3.56-62.50; P = 0.0002), and a longer surgical duration (OR, 1.01; 95% CI, 1.002-1.02; P = 0.01) were independent covariates for anastomotic leakage, and advanced age (OR, 1.08; 95% CI, 1.01-1.15; P = 0.02) and lower body mass index (OR, 1.16; 95% CI, 1.01-1.33; P = 0.04) were independent covariates for pneumonia. However, whether or not patients received nCRT was irrelevant. We found that nCRT is safe for three-incision esophagectomy and it does not increase the incidence of postoperative morbidity and mortality relative to esophagectomy alone.

Abstract
A case of esophageal carcinosarcoma is described herein. A 58-year-old man presented with dysphagia and was admitted to our hospital. Imaging studies revealed a type 3 tumor in the upper intrathoracic esophagus with direct invasion to the left main bronchus. Analysis of a biopsy specimen revealed carcinosarcoma. The patient underwent esophageal bypass and chemoradiotherapy. Eight months after surgery, he died of esophago-bronchial fistula. Autopsy examination revealed liver metastasis, peritoneal dissemination and intramural metastasis. The sarcomatous component was predominant in the intramural and liver metastatic lesions.

Abstract
In total, 16 patients with cytologically proven malignant effusion from colorectal cancer were treated by locoregional administration of the streptococcal preparation OK-432 alone or OK-432 plus the T-cell growth factor interleukin (IL)-2, and the action mechanism of the treatment was studied. A positive clinical response, showing a cytologic disappearance of cancer cells and decrease of effusion, was observed in nine of 11 (82%) patients treated with OK-432 alone and in all five patients treated with OK-432 plus IL-2. Flow cytometric analysis revealed that OK-432 plus IL-2 locally induced acute inflammation-like responses, including serial cellular infiltrations of granulocyte migration within a matter of hours, and activation of macrophages and T lymphocyte involvement within the following days, and that a predominant expansion of CD3+CD4+ lymphocytes (CD: cluster of differentiation) was induced by in vitro stimulation with IL-2 of locoregional cells after the OK-432 administration (OK/IL-2AK cells). The OK/IL-2AK cells produced tumour necrosis factor-α and interferon-γ, but these cells did not produce IL-4 and IL-6. The OK/IL-2AK cells expressed potent killing activity against autologous tumour cells. This activity was abrogated by treatment of the lymphocytes with anti-CD3, -CD4, -TCRαβ antibody, and by the treatment of target cells with anti-human leukocyte antigen (HLA)-DR antibody. The OK/IL-2AK cells expressed Fas-L gene, and flow cytometric analysis demonstrated HLA-DR expression in approximately 75% of CEA+ or cytokeratin+ effusion cells. TCRVβ gene analysis of the OK/IL-2AK cells showed an oligoclonal usage of TCRβ20, which was also involved in the cytotoxic mechanism of the OK/IL-2AK cells. Single-strand conformational polymorphism analysis demonstrated the clonotypes for the TCRVβ20 gene, and the CDR3s of the gene were sequenced. The clonotypic PCR using the TCRVβ20-CDR3 sequences could detect the CDR3-identical TCRs in effusion lymphocytes from the other patients. Taken together, it is suggested that locoregional administration of OK-432 plus IL-2 is highly effective for the management of malignant effusion from colorectal cancer. OK-432 plus IL-2 induces autologous tumour-reactive CD4+ Th1 killer lymphocytes, which recognise tumour antigen(s) presented with HLA class II molecules on effusion tumour cells by means of preferential usage of TCRVβ20. The clonotypic PCR using the TCRVβ20-CDR3 sequences may be informative for treating malignant effusion from colorectal cancer using OK-432 plus IL-2.

Abstract
Esophageal cancer is still one of the most widespread diseases, and surgery for esophageal carcinoma is very stressful for patients. Even though lymph node metastasis occurs more frequently in cases of early esophageal cancer than it does in cases of gastric cancer, surgeons prefer to avoid lymph node dissection if possible, thereby subjecting patients to less invasion. Thus, the aim of the present study was to examine the possibility of predicting lymph node metastasis on the basis of tumor location, quantification theory II analysis of tumor expression of genetic markers in primary esophageal cancer. Surgical specimens from 63 patients of esophageal cancer with submucosal invasion were examined for the relationship between tumor location and lymph node metastasis. In 19 of these 63 patients, p53, p21(Waf1, and proliferating cell nuclear antigen (PCNA) were examined immunohistologically, and to quantify the risk of lymph node metastasis, computer analysis was performed on the basis of quantification theory II, in which pathological lymph node metastasis (pN) was the objective variable and "high" or "low" expression of each of the three markers was the predictive variable. Tumors located in the lower third of the esophagus had no lymph node metastasis to the upper mediastinal region, and were thus indicated for trans-hiatal esophagectomy. A coefficient greater than 0.91 predicted node negative disease accurately without false-negative results; false-positive results were obtained for 54.5% of patients with a coefficient less than 0.064. Thus, we found that quantification theory II may be useful when considering indications for surgery without lymph node dissection in some cases of T1 esophageal carcinoma.

Abstract
In the present study, we demonstrate the treatment results of TS-1 on 22 gastric carcinoma patients (15 far advanced and 7 recurrent patients) from June 1999 to December 2000. TS-1 was administered at 75 mg/m2/day, twice daily per body for 28 days followed by a 14-day interval (1 cycle). Successful treatment was obtained in from 1 to 11 cycles, and we obtained 9 (47.4%) partial responses (PR), 7 stable disease (NC) and progressive disease (PD) among 19 evaluable patients. PR was obtained in 7 (58.3%) out of 12 primary lesions of the stomach. We also obtained 1 CR of liver metastasis and 4 PR of 9 distant lymph node metastases (44.4%). Moreover, malignant ascites disappeared in 4 (57.1%) out of 7 cases and PR was obtained in 3 (50%) out of 6 measurable cases of peritoneal disease. In addition, two patients had hydronephrosis which improved after 1 cycle of TS-1 treatment. The adverse effects observed were grade 3 bone marrow suppression in three cases, severe diarrhea in one case, one case of liver dysfunction and a few cases of nausea and vomiting. These results indicate that the oral tegafur compound, TS-1, is a new therapeutic tools for advanced and recurrent gastric carcinomas, especially peritoneal disease.

Abstract
The effect of the superior mediastinal lymph node dissection was compared retrospectively with that of standard dissection in 108 esophageal cancer patients. Five-year survival rates were 46.3% in patients who underwent standard surgery (group A) and 39.3% in patients who underwent superior mediastinal lymph node dissection (group B). The survival curves were basically the same. Nineteen out of 42 (45.2%) tumors in group A and 24 out of 66 (36.4%) tumors in group B recurred. The distribution of the first sites of recurrence did not differ significantly between groups. However, 14 tumors (67%) in group A recurred in the lymph nodes, but only seven tumors recurred (28%) in the lymph nodes in group B. Eleven tumors (52%) in group A recurred to superior mediastinal nodes, but only one tumor (4%) recurred to a superior mediastinal node in group B. Fourteen of the group B patients showed metastasis to superior mediastinal lymph nodes and none of these patients survived for more than 5 years. Eleven of these 14 patients showed metastasis to only one or two nodes. Based on our data and other reported findings, we conclude that extended lymphadenectomy of the superior mediastinal region alone does not contribute to improved survival of esophageal cancer patients, but it does contribute to the prevention of lymph node recurrence in this region.

Abstract
The in vitro generation of effector lymphocytes cytotoxic to cancer cells, was investigated with a mixed lymphocyte-tumor culture (MLTC) system using genetically modified human cancer cells, followed by stimulation with the interleukin (IL)-2 plus immobilized anti-CD3 antibody (IL-2/CD3) system. A gastric cancer cell line, GC022588 (HLA-A2, 24, B35, 55, C1,3), was retrovirally transduced with the human interleukin (IL)-2 gene (GC/IL-2) or the neomycin-resistance gene (GC/Neo). The secretion of biologically active IL-2 was detectable in GC/IL-2 cells but not in GC/Neo or parental GC022588 cells. The cytotoxic activity against the parental GC022588 cells of peripheral blood mononuclear cells (PBMC) was greater among PBMC activated with MLTC using GC/IL-2 than among those activated with MLTC using GC/Neo or without MLTC. The IL-2/CD3 stimulation could efficiently expand the effector lymphocytes without any reduction of the cytotoxic activity generated. The cytotoxic activity generated by this system was reproducible in several HLA-A2- or A24-positive donors. The effector lymphocytes could kill the other adenocarcinoma cells expressing HLA-A2 or A24. The phenotypes of the effector lymphocytes generated with the system were 40% CD4+ and 70% CD8+. Both phenotypes may have been responsible for the cytotoxicity. The removal of adherent cells from PBMC before the MLTC did not affect the generation of cytotoxicity, whereas neutralization of tumor-derived IL-2 with a specific antibody during the MLTC significantly inhibited the generation of cytotoxicity. These results suggest that IL-2 gene-transduction augments the immunogenicity of the tumor cells that efficiently stimulate lymphocytes to be cytotoxic, and that the IL-2/CD3 system may be practical for the expansion of effector lymphocytes for use in adoptive immunotherapy for cancer. The mechanism by which IL-2 gene-modified tumor cells stimulate immune reactivity was discussed.

Abstract
We studied the thymidine kinase (TK) gene and the interleukin (IL)-2 gene co-transduction into tumor cells for a possible strategy of cancer gene therapy. A murine ovarian cancer cell line, OVHM, was retrovirally transduced with the TK (OVHM/TK) or the IL-2 gene (OVHM/IL-2). The TK or IL-2 expression was permanent in OVHM/TK or OVHM/IL-2. OVHM/TK cells were susceptible to gancyclovir (GCV) in vitro, and their intraperitoneal growth was completely regulated with GCV administration. The bystander effect was not observed in vitro and in vivo in this model, and only the marginal emergence of immune involvement was observed in the OVHM/TK-cured mice with GCV. OVHM/IL-2 cells produced IL-2 biologically active to be immunogenic, but still tumorigenic to kill the mice when inoculated intraperitoneally. Then, OVHM/TK cells were co-transduced with the IL-2 gene to establish OVHM/TK/IL-2 cells. OVHM/TK/IL-2 cells were also susceptible to GCV and transiently produced active IL-2. A significant resistance against the challenge of parental tumor cells was observed in the mice that were inoculated with OVHM/TK/IL-2 cells and cured with GCV administration. It is suggested that tumor cells transduced with both TK and IL-2 genes could be regressed with GCV administration with subsequent generation of immune activation in the host. Since the bystander effect may not always be a common phenomenon in gene therapy using the TK gene, this type of combination may be advantageous in the clinical application of gene therapy for human cancers.

Abstract
The immunological properties of interleukin-2 (IL-2) gene-transduced tumor cells were investigated in mice. A murine ovarian cancer cell line, OVHM, was retrovirally transduced with the human IL-2 gene (OVHM/IL-2) and the neomycin resistance gene (OVHM/Neo). OVHM/IL-2 cells continuously secreted IL-2 detected by ELISA using an antibody specific for human IL-2, and by a bioassay using an IL-2-reactive cell line (CTLL-2). When OVHM cells were inoculated subcutaneously into syngeneic B6C3F1 mice, OVHM/IL-2 cells but not parental (OVHM/P) or OVHM/Neo cells were regressed even though their rate of in vitro growth was comparable. This was not observed in nude mice, indicating the involvement of T lymphocytes in the regression of OVHM/IL-2 cells. The survival of mice inoculated intraperitoneally with OVHM/IL-2 cells was prolonged compared with those inoculated with OVHM/P cells. In irradiation experiments, IL-2 secretion by irradiated OVHM/IL-2 cells was retained for at least 5 days, although in vitro growth and in vivo tumorigenicity of irradiated OVHM/IL-2 cells were completely diminished. When mice were challenged with viable OVHM/P cells, survival of mice previously immunized with irradiated OVHM/IL-2 cells was prolonged compared to those immunized with irradiated OVHM/P cells, indicating a vaccine property of irradiated OVHM/IL-2 cells. Moreover, survival of mice with established ascites was improved upon injection of irradiated OVHM/IL-2 cells, indicating a therapeutic potential of OVHM/IL-2 cells. Tumor cells genetically engineered to secrete IL-2 may therefore be promising candidates for tumor vaccines and may provide a new mode of cancer immunotherapy.

Abstract
Recently, various cell cycle regulators have been investigated as biological markers of malignant potential. These regulators might influence the survival rate and the effect of adjuvant therapies. In this study, we analyzed p53, p21(Waf1/Cip1) and cyclin D1 expression in 64 esophageal cancer patients and the relationship between clinicopathologic parameters and patient survival. The positive expression rate was 48.4%, 42.2% and 43.8% in the p53, p21 and cyclin D1 groups respectively. Multivariant analysis revealed that tumor depth, chemotherapy, p53, p21 and cyclin D1 expression showed significant values. p53- and cyclin D1-negative patients had a worse prognosis. p21-positive patients had a better prognosis. In stage 0, I and II patients, there was a significant difference between p53-positive and -negative, p21-positive and -negative, and cyclin D1-positive and -negative groups. In stage III and IV patients, there was no significant difference between any two groups. However, a significant difference was seen in the p21 group: among patients who received adjuvant chemotherapy, the p21-positive group had a 5-year survival rate of 50% compared with 13.4% in the p21-negative group (not significant).

Abstract
Nine T-cell clones have been established from tumor-infiltrating lymphocytes (TIL) isolated from ascitic fluid of a gastric cancer patient. Five of them retained cytotoxicity against autologous tumor cells (AuTu), and were all CD4+. Each clone had different usage of T-cell receptor (TCR) V beta gene as assessed by Southern blot analysis. Using AuTu and two allogeneic gastric cancer cell lines as targets, we selected three clones with unique cytotoxic properties. Two of these clones (Clone 1 and 2) preferentially lysed AuTu, but showed no or marginal cytotoxicity against allogeneic gastric cancer cells, and one clone (Clone 7) showed appreciable cytotoxicity against AuTu and allogeneic gastric cancer cells. In the detailed analysis of TCRV beta gene usage, Clone 1, 2, and 7 expressed V beta 13.1/D beta 1/J beta 1.5/C beta 1, V beta 3/D beta 2/J beta 2.4/C beta 2, and V beta 9/D beta 1/J beta 1.4/C beta 1, respectively, and the primary structures of the three TCRVb genes did not share any common features, neither in the sizes of their complementarity determining region 3 (CDR3) nor in their amino acid compositions. Interestingly, PBL of the same patient expressed CDR3 identical to that of Clone 2 and 7, but not that of Clone 1. CDR3 identical to that of Clone 2 and 7 were also detected in TIL of other gastric cancer patients. These results show that some AuTu-specific CTL included in TIL are circulating in peripheral blood, and that the CDR3 identical to that of the CTL is expressed extensively in TIL among different gastric cancer patients. Screening of the expression of the CDR3 in other gastric cancer patients is recommended to develop an immuno-therapy of gastric cancer based on antigenic peptide.

Abstract
To determine the significance of interleukin (IL)-10 in antitumor immune response, the effect of the down-regulation of tumor-derived IL-10 on locoregional immunotherapy was investigated. C3H/HeN mice were intraperitoneally (i.p.) inoculated with IL-10-producing murine breast cancer cell line, FM3A, and treated with locoregional administration of OK-432 with or without anti-IL-10 monoclonal antibody (mAb). Anti-IL-10 mAb did not affect the in vitro growth of FM3A cells. Administration of OK-432 plus anti-IL-10 mAb remarkably delayed the retention of malignant ascites and prolonged the survival of mice compared with the administration of OK-432 alone. Spleen cells which were collected from mice treated with OK-432 plus anti-IL-10 mAb and further stimulated in vitro with inactivated FM3A cells exhibited significantly higher cytotoxicity against FM3A cells than those from mice treated with OK-432 alone or from the control mice. The expression of major histocompatibility complex (MHC) class II molecules on spleen cells was up-regulated in vitro by the addition of OK-432 and anti-IL-10 mAb. Using semi-quantitative reverse transcription-polymerase chain reaction (RT-PCR), cytokine mRNA levels of peritoneal exudate cells (PEC) and spleen cells were assessed on day 7 (before treatment) and day 14 (after treatment). In PEC, increased expression of IL-2 was observed with the administration of OK-432 plus anti-IL-10 mAb. In spleen cells, the expression of IL-2, IL-12 and IFN-gamma were strongly induced, and IL-4 expression was reduced by the administration of OK-432 plus anti-IL-10 mAb. It is suggested that down-regulation of tumor-derived IL-10 induces the up-regulation of the T helper type (Th) 1 population, resulting in an enhancement of the efficacy of locoregional immunotherapy with OK-432.

Abstract
We generally choose transhiatal esophagectomy (THE) for patients with high risk for postoperative complications and for carcinoma of the lower thoracic esophagus, even if the tumor is in the advanced stage. In order to define indications for THE in esophageal cancer patients, we investigated 40 THE cancer patients according to the expressions of EGF/EGFR, p53 and p21. In patients with stage I, II, III and IV tumors, 5-year survival rates were 66.7%, 28.6%, 30.0% and 11.4%, respectively. The sites of first recurrence were the lymph nodes (n = 10) and single organs (n = 10). Dissemination (n = 3) and local recurrence (n = 2) were also seen as a first recurrence. According to EGF/EGFR, 5-year survival rate was 69% and 14% in the low and high EGF/EGFR groups, respectively. According to p53 expression, 5-year survival was 60% and 30% in the negative and positive groups, respectively; according to p21 expression, 5-year survival was 71% and 0% in the negative and positive groups, respectively. Significant difference was seen in EGF/EGFR and p21 groups. These data support less invasive surgery for some patients even for esophageal cancer patients. THE is a less invasive surgery, that also implies fewer curative procedure. Our results also showed that THE alone will be the only curative procedure necessary for some patients. We can determine therapeutic procedures using these new factors, and thus avoid unnecessary excess surgical stress in esophageal cancer patients.

Abstract
OBJECTIVES The aim of this study was to evaluate the efficacy of adjuvant chemoradiotherapy following surgery in patients with advanced esophageal cancer. SUBJECTS AND METHODS We followed the cases of 57 such patients treated at our hospital, involving 19 who received adjuvant chemoradiotherapy (CR group), 19 who received radiotherapy alone (R group), and 19 who did received neither (N group). In the CR group, chemotherapy, consisting of cis-diaminodichloroplatinum (CDDP), 5-fluorouracil (5-FU), and etoposide (VP-16), was combined with radiotherapy was administered from 4 weeks after surgery. Concurrent radiotherapy was started at 3 weeks after esophagectomy. CDDP at 50 mg/m2 was administered on days 1 and 7.5-FU at 500 mg/m2 and VP-16 at 60 mg/m2 were administered on days 3, 4, and 5. Thirteen patients (68.4%) were treated with more than 2 cycles of chemotherapy combined with radiation. RESULTS Side-effects of severe anorexia (grade 3) and leukocytopenia (< 1900/microliter) were observed in 47% and 39% of the patients, respectively. However no treatment-related death was observed. The 5-year-survival rate was 25.2%, 18.9%, and 15.8%, in the CR group, R group, and N group, respectively. The recurrence rate was 66.7% in the CR group, which was higher than in the matched control groups (46.2% in the N group and 54.5% in the R group), but with no a significant difference. CONCLUSION These results suggested that adjuvant chemoradiotherapy did not contribute to improvement in prognosis for these patients with advanced esophageal cancer.

Abstract
A 79-year-old male diagnosed as advanced hepatocellular carcinoma with portal invasion was treated by continuous intra-arterial chemotherapy of 5-FU, which was continuously administered for 72 hours at a dose of 333 mg/mm/day every 2 weeks and repeated 12 times. Total dose of 5-FU was 14.4 g. Toxicity of this therapy was not recognized. Levels of AFP were reduced from 4385.6 ng/ml to 11.9 for 6 months. No tumor was recognized on CT scan at 6 months after starting this therapy, after 15 months of this therapy, the patient is alive and disease-free. Given the above results, continuous intra-arterial administration of this 5-FU therapy may be effective for patients with hepatocellular carcinoma.

Abstract
The possible use of percutaneous transhepatic microwave tissue coagulation therapy (PMCT) using ultra-sonography under local anesthesia for solitary liver cancer was studied. The subjects were 8 patients having primary or metastatic liver cancer with solitary liver tumor less than 4 cm in size, consisting of 2 hepatocellular carcinomas, and 6 metastatic carcinomas. PMCT was performed continuously 3 times at the output of 30 watts for 30 seconds at a time. Tumors less than 3 cm in size were completely coagulated by irradiation from 2 to 5 times judged by enhanced CT. No recurrence of tumor was recognized in the coagulation area. But in some cases, multiple metastases were found at another site in the liver by 3 months after PMCT. Thus, the results suggest that PMCT is a useful therapy for small liver tumor as a local control.

Abstract
Because of the development of the subcutaneous implantable port, intra-arterial infusion chemotherapy for malignant tumor has been performed in safety and it is now possible to choose a more effective method of drug administration. Many problems remain, however. In this study, we investigated the performance of subcutaneous implantable port with a new one-way valve with safety, septum intensity and a back stream of blood. This new port was very safe, with good septum intensity and water backflow. In the performance test with a back stream of water into the catheter, water did not back up into the catheter connecting with the port with the one-way valve, but did so without the one-way valve after releasing a load of 2,000 g from the septum. This suggests that the catheter obstruction is decreased by adding a one-way valve to the port.

Abstract
T-cell receptor (TCR) gene rearrangements were analyzed in tumor-infiltrating lymphocytes (TIL) using the reverse transcription-polymerase chain reaction (RT-PCR) to determine whether oligoclonal expression of TCRV beta occurs in TIL, and if so, whether it is involved in the clinical response and mechanisms of locoregional immunotherapy using a streptococcal preparation, OK432. Patients with malignant effusion of various origins were treated with intrapleural administration of OK432, and clinical responses were assessed by cytological and chest X-ray examinations. Pleural exudate cells (PEC), obtained before and after the administration of OK432 (designated as pre- and OK432-PEC, respectively), were subjected to TCR analysis. Both pre-PEC and OK432-PEC showed highly diverse expressions of TCRV beta gene usage in either type of PEC. The frequency of TCRV beta 20 gene expression in OK432-PEC was significantly higher than in pre-PEC. Moreover, the over-expression of the TCRV beta 20 gene usage was also induced in the peripheral blood lymphocytes and pre-PEC of patients by in vitro OK432 stimulation, but not in the PBL of one healthy volunteer. Single-strand conformational polymorphism (SSCP) analysis revealed the clonotypes of these TCRV beta 20 genes. Autologous tumor-specific killing activity could be detected in OK432-PEC and was significantly reduced by treatment with a TCRV beta 20-specific monoclonal antibody. These findings suggest that the rearrangement of TCRV beta 20 gene usage may be involved in the autologous tumor-specific action of malignant effusions in the treatment with OK432.

Abstract
We analyzed the T cell receptor (TCR) V beta repertoire of lymphocytes obtained from patients with malignant effusion treated by locoregional immunotherapy. Polymerase chain reaction using a panel of V beta subfamily specific oligonucleotide primers(V beta 1-20) was employed after reverse transcription of mRNA isolated from the locoregional cells. No major oligoclonality of TCR repertoire was observed in effusion lymphocytes before the treatment. The expression level of V beta 13.1 repertoire was significantly higher in effusion lymphocytes than in peripheral blood lymphocytes before treatment. V beta 20 gene expression increased significantly after locoregional administration of OK-432. It is suggested that TCR V beta 13.1 may be responsible for effusion lymphocytes and TCR V beta 20 for OK-432-related antigenic stimulus.

Abstract
A 52-year-old woman was admitted to our hospital with the chief complaint of left anterior chest pain. A chest X-ray showed a tumor shadow in the left 4th rib. No abnormalities were detected in peripheral blood and aspirated bone marrow samples. The tumor was surgically resected with the involved bone, the intercostal muscle and the parietal pleura. The resected specimen contained a 3 x 6 x 3 cm lesion, and histological investigation of the tumor revealed a plasmacytoma of the rib. It relapsed as a multiple myeloma within two months after surgery. Chemotherapy was administered and the bone lesions were observed to disappear. We believe that the best way to treat solitary plasmacytoma is to first resect the solitary tumor, and then to add cobalt irradiation and chemotherapy after surgery.
