Two cases of advanced gastric cancer effectively treated with chemotherapy of 5-fluorouracil, cisplatin and cytarabine

We reported two cases of advanced gastric cancer effectively treated with chemotherapy of 5-fluorouracil (5-FU), cisplatin (CDDP) and cytarabine (Ara-C), 5-FU (300-350 mg/body) was given by continuous intravenous infusion. Ara-C (20-40 mg/body) by continuous infusion and CDDP (15-20 mg/body) were added intravenously for 3-6 days. For case 1, epirubicin (30 mg/body) was also given on the first day of each therapy course. Case 1 was a 62-year-old female who had gastric cancer with liver metastasis, ovarian metastasis and peritonitis carcinomatosa. After 3 courses of the chemotherapy, reduction of ovarian metastasis greater than 75% was observed. The value of CA125 decreased from 6,800 U/ml to 527 U/ml and ascites disappeared. Case 2 was a 54-year-old male who had type 3 advanced gastric cancer with multiple liver metastases. He received 6 courses of the therapy. Both primary and metastatic tumors showed over 50% reduction in tumor size. These suggested that this combination therapy was effective for inoperable advanced gastric cancers.     

Repeated hepatic arterial infusion chemotherapy using an implanted port system in patients with unresectable malignant liver neoplasms: significant factors affecting early hepatic arterial occlusion

The purpose of this study was to identify significant factors affecting early hepatic arterial occlusion in patients who received repeated hepatic arterial infusion chemotherapy using an implanted port system. Eighty-five patients with unresectable liver neoplasms who underwent implantation of the port system were studied. Arterial infusion chemotherapy was performed every 1-4 weeks. Arterial occlusion was evaluated by hepatic arteriography performed via the port every 3 months. Twenty variables were analyzed using univariate and multivariate analyses to identify significant factors affecting early hepatic arterial occlusion. Hepatic arterial occlusion was found in 25.9% (22/85) of the patients. Thirteen of them experienced early arterial occlusion within 6 months. The mean survival period was significantly worse in patients who experienced early arterial occlusion than those who did not (16 months vs. 26 months, p<0.05). In the multivariate analysis, the following 3 variables had independent value for early arterial occlusion; i). diameter of the common hepatic artery, ii). gender, and iii). previous systemic chemotherapy. Early arterial occlusion affects therapeutic effects and survival in patients who undergo arterial infusion chemotherapy with an implanted port. Factors demonstrated here are important to classify patients at risk of early hepatic arterial occlusion.     

America: where kids are getting killed

Two cases of liver metastasis from colon cancer were treated by percutaneous ethanol (PEI) and acetic acid (PAI) injection for the recurrent lesion after surgery. Case 1 was a 60-year-old female who received sigmoidectomy with partial hepatectomy, and intraarterial 5-FU infusion was done after surgery. One year later, recurrence of liver tumor was detected, and PEI and PAI were performed for the metastatic lesions of the liver. Tumor regression and histopathological examination revealed coagulative necrosis. The patient died of lung metastasis 2 years and 10 months after treatment. Case 2 was a 58-year-old-male with ascending colon cancer and liver metastasis, who received surgery, and chemotherapy with intraarterial 5-FU infusion was continued. Four months later, recurrence of liver metastasis with elevation of serum CEA was noted. The patient received PEI three times and CEA decreased. Re-operation of hepatectomy revealed complete necrosis at the site of PEI. The patient has been alive for 1 year and 6 months with a new recurrence in the liver and is receiving repeated PEI therapy. PEI and PAI seem to be useful for the treatment of unresectable liver metastasis.     

Twin pregnancy with one fetus in a rudimentary horn: a case report of a surviving twin

We report herein the case of a 30-year-old man who developed a primary leiomyosarcoma (LMS) 11 years after undergoing a median sternotomy for mediastinal seminoma followed by 50 Gy radiotherapy. He was given two courses of chemotherapy, resulting in 90% tumor regression, after which resection of the tumor with adjacent chest wall structures was carried out. Reconstruction was performed using a methylmethacrylate prosthesis prepared preoperatively. Postoperatively, he received two additional courses of chemotherapy and has had no sign of recurrence for 45 months.     

The preventive effect of weekly high-dose 5-FU infusion (WHF) after resection of hepatic metastasis from colorectal cancer

Hepatic metastasis is often found even after resection of hepatic metastases from colorectal cancer. This implies that the micrometastasis already existed in residual liver when the resection was performed, and so complete recovery with resection alone is rare. We have been using a weekly high-dose 5-FU HAI (WHF = 5-FU 1,000 mg/m2/5 hrs/qw) since 1991, which has preventive effects for metastasis in residual liver as compared to a group treated without infusion chemotherapy. Hepatectomy was performed in 30 of 113 cases of hepatic metastasis from colorectal cancer during the past 16 years. For comparison, we divided the 30 cases into group A1 (16 cases H1:12, H2:4), which received hepatectomy only, and group A2 (14 cases H1:8, H2:4, H3:2), which additionally received infusion chemotherapy. The 1- and 3-year (cumulative) survival rates were 64.6% and 32.3% in group A1, and 100% and 75.3% in group A2 respectively in which the treatment outcome was significantly higher. The 1- and 3-year recurrence rates were 41.7 and 66.3 in group A1, and 8.3% each in group A2, respectively, which reveals that metastasis in residual liver was controlled in group A2. Other metastases were seen in lung (6 cases), bone (2 cases), hepatic hilar lymph node (3 cases), brain (1 case) and local (3 cases) in group A1, while only one metastasis in each brain and locally was seen in group A2 so far. WHF after resection of hepatic metastasis from colorectal cancer has a preventive effect not only for the recurrence in residual liver but also for other metastases. Therefore, as improvement in the survival rate is expected.     

Evaluation of hepatic resection and hepatic arterial infusion chemotherapy for multiple liver metastases from colon cancer

We examined the significance of hepatic resection and hepatic infusion chemotherapy for multiple liver metastases from colon cancer. Twelve patients underwent curative hepatic resection for multiple liver metastases (more than five), and 10 of them received arterial infusion chemotherapy. The number of metastases ranged 5 to 30 (mean 9.4). Recurrence rates in the remnant liver were 50%, and five-year survival rates were 31%.     

Circadian chemotherapy in cancer patients

Continuous infusion of 5-FU at night was performed for four patients: three had liver metastasis (one with gastric cancer and two with rectal cancer) and one had local recurrence of rectal cancer. The chemotherapy schedule was 400 mg/m2/day 5-FU intraarterial or intravenous infusion from 6:00 p.m. to 6:00 a.m. for five days repeated every 3 weeks. There were one complete response, two partial responses and one with no change. It is expected that the chemotherapy of 5-FU at night will result in a high efficacy and lower toxicity.     

Successful treatment of recurrent multiple lung metastasis from colon cancer with combination chemotherapy using methotrexate, 5-fluorouracil, and high-dose leucovorin: a case report

A 66-year-old man, who had received sigmoidectomy for sigmoid cancer in 1985, was diagnosed as having multiple lung and liver tumors in September 1988. When celiac-angiography was performed, recurrent liver metastases from sigmoid cancer were suspected and he received a transarterial embolism with ADM 30 mg and MMC 20 mg. In addition, he was treated with a sequential chemotherapy with methotrexate (MTX), 1,200 mg intravenously (6 h-infusion) followed by 5-fluorouracil (5-FU), 600 mg/m2/day and leucovorin, 300 mg/body/day in continuous infusion for 5 days from day 2 with concomitant oral administration of dipyridamole (300 mg/day) over 14 days. Treatment was repeated every 28 days for two courses. For the third course, administration of only 5-FU, leucovorin and dipyridamole was performed. As a result, the size of pulmonary lesions was prominently reduced on computed tomography. Although mucositis, anal erosion, diarrhea and thrombocytopenia were noted, no severe side effects were observed. This sequential chemotherapy appears useful for metastatic lesions from colon cancer.     

Clinical evaluation of postoperative adjuvant arterial infusion chemotherapy in resected hepatoma patients

Eighty surgically treated patients with advanced hepatocellular carcinoma (HCC) were divided into two groups. In group I, twenty patients whose mean diameter of tumors was 56 mm, prophylactically underwent hepatic arterial infusion chemotherapy after liver resection. Chemotherapeutic agents (5-FU, ADM, MMC, CDDP, Lipiodol) were administered 4 times a year via Infuse A port. The remaining 60 patients, whose mean diameter of tumors was 57 mm, served as the control without prophylactic infusion (group II). The 2-year cumulative survival rate was higher in the prophylactic group (71%) than the control (48%, p = 0.040). The two-year disease-free survival rate was improved in group I (38%) compared with that in group II (27%, p = 0.021). Intrahepatic multiple recurrence within 1 year after surgery was recognized in four out of 18 patients of group I (22%) and in thirty-three out of 60 patients of group II (55%, p = 0.029). In group I, two cases who died of hepatic failure with no recurrence, had lower functional reverse and a larger amount of Lipiodol than the remaining 18 patients. Adjuvant arterial infusion chemotherapy can thus be be efficacious in alleviating hepatoma recurrence after liver resection. For patients with poor liver function, a smaller volume of chemotherapeutic agents might be feasible.     

Locoregional injection of OK-432/fibrinogen/thrombin for unresectable metastatic liver tumors

We performed the locoregional injection of OK-432/fibrinogen/thrombin to unresectable hepatic tumors metastasized from colorectal cancers, which were hardly controlled by arterial infusion chemotherapy. CEA was markedly decreased following this treatment, although abdominal CT did not show a significant reduction of tumor mass. This immuno-injection therapy may be a choice of treatment for metastatic liver tumors, refractory to treatment by conventional chemotherapy.     

Plexosarcoma of the bladder

Retroperitoneal fibrosarcoma is a rare disease that has proven difficult to treat due to its high incidence of postoperative local recurrence. We recently experienced a patient in whom retroperitoneal fibrosarcoma was followed by liver metastasis without local recurrence. A 34-year-old woman who initially presented with right upper quadrant pain was found to have a retroperitoneal tumor by diagnostic imaging techniques. Extirpation of the tumor was performed and the histopathological diagnosis was fibrosarcoma. A solitary metastasis was detected in the lateral segment 1 year after this operation and a lateral segmentectomy was carried out; however, a short time later, multiple liver metastases were found. Initially, ethanol injections were given with little effect, following which CYVADIC chemotherapy, consisting of cyclophosphamide, vincristine, farmorubicin, and dacarbazine was administered. An excellent responsiveness without severe toxicity was achieved after five cycles, with a significant reduction in tumor size, being estimated as a complete response. Thus, we consider that this chemotherapy regimen could be a promising mode of treatment for liver metastasis from retroperitoneal fibrosarcoma without local recurrence.     

Intraarterial chemotherapy via reservoir system for far-advanced bladder and prostate cancer

A clinical study was performed on the efficacy of intraarterial chemotherapy using reservoir system for far-advanced urological malignancy. The reservoir system was indwelled in the femoral subcutaneous layer using Seldinger's method. Fifteen cases with inoperable complicated advanced bladder cancer and ten cases with postoperative local recurrent bladder cancer received intraarterial chemotherapy using the reservoir system. Then, 23 cases with local relapsed prostate cancer and two cases with endocrine-resistant prostate cancer received chemotherapy. The administered anti-cancerous agents were methotrexate, cis-platinum and adriamycin, and 5-FU or carboplatin were administered as maintenance therapy. The mean courses of chemotherapy were six for bladder cancer and four for prostate cancer. During stabilization of the local lesion, no distant deterioration was recognized. Overall clinical efficacy was as follows: PR:18 cases and NC:7 cases for bladder cancer; then, PR:11 cases and 14 cases for prostate cancer. The median duration of stabilization was as follows: 23 months for bladder cancer and 12 months for prostate cancer. Complications were fewer than with systemic chemotherapy.     

Carcinosarcoma in a bladder diverticulum

A 47-year-old man presented with hematuria and dysuria. He was found to have a carcinosarcoma originating from a bladder diverticulum. He underwent a partial cystectomy and received postoperative chemotherapy. One year later, he presented with a large local recurrence and died shortly afterward. We believe this to be the second case of a carcinosarcoma originating in a bladder diverticulum.     

Clinical stage IE primary lymphoma of the nasal cavity: radiation therapy and chemotherapy

PURPOSE: To determine the appropriate radiation therapy and chemotherapy for primary lymphoma of the nasal cavity to improve the local control and survival rates. MATERIALS AND METHODS: Of the 25 adult patients with stage IE nasal lymphoma, nine underwent local radiation therapy alone and 16 underwent radiation therapy and chemotherapy (intravenous infusion). Radiation doses to the involved area were 22-54 Gy (median dose, 49 Gy). RESULTS: The 5- and 10-year cause-specific survival rates were 91% and 73%, respectively. The 5- and 10-year disease-free survival rates were 83% and 59%, respectively. Eight patients developed recurrent disease: six at the local site, one in the cervical nodes, and one in the small intestine. Five of the six patients with local recurrence received less than 50 Gy. Four of the six patients developed recurrent disease in the treated area; the other two patients developed marginal recurrences. Prognostic factors such as age, sex, maximum tumor size, and lactate dehydrogenase level were of limited value. CONCLUSION: The most common recurrence site was the local site. To improve the local control rate, the involved area should be treated with high-dose radiation therapy. The clinical results did not demonstrate the usefulness of combination chemotherapy for stage IE nasal lymphoma.     

Hemodynamic response to oxygen administration in chronic heart failure: role of chemoreflexes

OBJECTIVE: To determine the applicability and safety of an ifosfamide, cisplatin, and etoposide (VIP) regimen as a neoadjuvant chemotherapy to a concomitant thoracic radiotherapy and cisplatin continuous infusion in locally advanced non-small cell lung cancer (NSCLC). PATIENTS AND METHODS: Forty-four patients (stage IIIb in 43 and stage IIIa in 1) entered a study of VIP, followed by concomitant thoracic radiotherapy and cisplatin continuous infusion. Chemotherapy consisted of three courses of cisplatin 25 mg/m2, ifosfamide 1.5 g/m2 (with uroprotection), and etoposide 100 mg/m2 given on days 1 to 4 of a 21-day cycle with hematopoietic support using recombinant human methionyl granulocyte colony stimulating factor. Patients who achieved a response or a stabilization were planned to receive a split-course normofractionated thoracic radiotherapy (first course: 30 Gy/10; 4-week rest period; second course: 25 Gy/10). A continuous cisplatin infusion of 6 mg/m2 daily was administered using an autonomous chemotherapy delivery device. Total plasma platinum titration was performed daily during the two courses in five of the patients. Analyses were done on an intent-to-treat basis. RESULTS: Thirty-nine of the 44 patients received the three-cycle chemotherapy program. Received dose intensity was 82%. Thirty-eight patients received the radiotherapy and, among them, 35 received the complete concomitant continuous cisplatin infusion. Objective (complete) response rates were 48% (7%) at the end of chemotherapy and increased up to 61% (16%) by the end of radiotherapy. At the end of the first radiotherapy cycle, the mean total plasma platinum concentration was twice as high as that of the residual postinduction chemotherapy concentration. During induction chemotherapy, myelosuppression was the limiting toxicity requiring hospital readmission in 23 patients. During radiotherapy, the main toxicity was acute esophagitis. A relatively high rate of pulmonary fibrosis was observed using the subjective objective management analytic--late effects of normal tissue score without life-threatening pulmonary function impairment. None of the patients died from toxic reactions. Probability of survival at 1, 2, and 3 years was 49%, 19%, and 5%, respectively. Primary cause of failure was a local relapse in 63% of the patients, brain metastases in 24%, and hematogeneous metastases to other sites in 13%. CONCLUSION: Neoadjuvant VIP followed by concomitant radiotherapy-chemotherapy is feasible, but the split-course radiotherapy did not prevent a high rate of local recurrences. The high rate of toxic reactions requiring hospital readmission limits further development of such an aggressive regimen in NSCLC.     

Hepatic arterial chemotherapy for liver cancer over a period of 8 years

Hepatic arterial chemotherapy was performed for 27 patients with primary (3), metastatic liver cancer (21), and 3 other cases, over a period of 8 years. Chemotherapy was performed by intermittent hepatic arterial infusion of 5-FU or FAM (in case of metastatic tumor from colorectal cancer), FAM (from gastric cancer), and CDDP or Farmorubicin (HCC). Hepatic resection was performed in 10 cases of metastatic tumor from colorectal cancer, and 8 cases of 10 were curative operation. The 5-year survival rates of curative liver resection group, and non-curative liver resection or non-resection group were 57.1% and 12.5%, respectively. As is the case with metastatic cancer from gastric cancer, pancreatic cancer, and hepatocellular carcinoma (HCC), the prognosis was poor except for one CR case of HCC. We concluded that hepatic arterial chemotherapy may be recommended for a curative resected case of liver metastasis from colorectal cancer.     

Intra-arterial preventive chemotherapy for residual liver after resection of hepatic metastasis from colorectal cancer

We treated 18 cases with intra-hepatic arterial infusion chemotherapy after resection of hepatic metastasis from colorectal cancer (June 1991-September 1997). Eight cases were H1, 7 were H2, and 3 were H3. Hepatic lobectomy was done in 3 cases, lobectomy + partial resection in 2 cases, and partial resection in 13 cases. All cases received high-dose intermittent 5-FU infusion (WHF = 5-FU 1,000 mg/m2/5 hrs/w) on an outpatient basis. The total frequency of WHF was 4-54 times (average 29), and total 5-FU doses ranged from 6.0 to 81.0 g (average 40 g). The 1- and 5-year cumulative survival rates were 100% and 77.5% in all patients 100% and 87.5% in H1 group and 100% and 64.3% in H2 + H3 group, respectively. There was no significant difference of survival between the H1 and H1 + H3 groups. The 1- and 5-year recurrence rates in residual liver were 5.9% and 14.4%, respectively. One of 2 cases with residual liver recurrence was resected for metastasis again, and the patient is now in a disease-free state. WHF after resection of hepatic metastasis from colorectal cancer has a preventive effect for their survival, not only in H1 group but also in H2 + H3 group.     

A genome-wide scan for human obesity genes reveals a major susceptibility locus on chromosome 10

PURPOSE: To clarify the clinical feasibility of getting a long-term arterial access at the subclavian region by directly puncturing the artery under ultrasound guidance. MATERIALS AND METHODS: Percutaneous placements of arterial infusion catheters with implantable ports were performed in 30 patients with malignant abdominal tumors. The axillary artery in the subclavian region was punctured directly with an 18G needle under ultrasound guidance. Using the Seldinger technique, a 5Fr catheter was placed with its tip in the hepatic or the other tumor-supplying arteries. The catheter was connected to an implantable port, and both of them were embedded in the subcutaneous pocket. RESULTS: Percutaneous placements of infusion catheters were successfully performed in 29 cases. Transarterial chemotherapy through implanted ports was done uneventfully in 26 patients, while in the other three cases, catheter dislodgment occurred. Two local haematomas, one wound infection and one cerebellar infarction were also experienced. CONCLUSION: Ultrasound-guided subclavian approach is a minimally invasive way of implanting an infusion catheter for chemotherapy, although its indication for severely atherosclerotic patients should be limited.     

Development of neurosurgery in southern California and the Los Angeles county/University of Southern California Medical Center

We reported a case of successful treatment of bilateral pulmonary metastasis from rectal cancer with high-dose 5'-DFUR plus MMC combination chemotherapy. A woman born in 1948 showed a recurrence in the bilateral lung about 29 months after low anterior resection. High-dose 5'-DFUR plus MMC combination chemotherapy was started in March, 1991. The chest X-ray examination 8 weeks after beginning this therapy showed a remarkable decrease in the size of the pulmonary metastatic foci and CEA decreased in the same way. The dose of 5'-DFUR was reduced after 5 courses, and then CEA increased. No remarkable side effect was encountered and the patient could be safely treated at an outpatient clinic. During this therapy no recurrence has been detected, and we performed a resection of the bilateral pulmonary metastasis by median sternotomy in October, 1991. The above findings suggested that this was an effective and safe therapy for pulmonary metastasis from colon cancers and could be a neo-adjuvant chemotherapy for surgical resection of pulmonary metastasis.     

Rating health information on the Internet: navigating to knowledge or to Babel?

A case of prostatic rhabdomyosarcoma in an 8-year-old boy is presented. He was referred to Kurobe City Hospital with chief complaints of urinary retention and fever. Radiologic examinations revealed a huge prostatic tumor. Prostatic needle biopsy was performed and the pathological diagnosis was embryonal rhabdomyosarcoma of the prostate. He was referred to our hospital and treated with chemotherapy consisting of cisplatin, vincristine, cyclophosphamide, adriamycin, actinomycin-D and radiotherapy based on the regimen of IRS III. Total prostatectomy was performed 6 months after the start of therapy. Viable tumor cells were found in the prostate and the left obturator lymph nodes. After the operation, we continued chemotherapy. No recurrence was observed 8 months after the operation. However, local recurrence occurred in the pelvis 10 months after the operation and he died 2 months after the recurrence.
