Combination chemotherapy with 5-FU and CDDP or CDDP analog for head and neck cancer

Combination chemotherapy with CDDP and 5-FU is one of the effective regimens for head and neck cancer. We studied the difference in the effects and adverse effects between two kinds of schedules of CDDP administration for CDDP-5-FU combination chemotherapy. For 13 patients, CDDP was administered on 5 consecutive days from day 1 to day 5 at a daily dose of 16 mg/m2 (Regimen A). For 14 patients CDDP was administered 80 mg on day 1 (Regimen B). 5-FU was administered 700 mg/m2/ day as a continuous drip infusion for 120 hours from day 1 to day 5. For regimen A, the response rate was 77%; for regimen B, it was 64%. The pattern of adverse effects showed a difference. Regimen B was more toxic for renal function than regimen A. But regimen A showed toxicity for bone marrow function. Acute phase nausea and vomit appeared more frequently in regimen B. The difference in the adverse effect pattern, which depends on the schedule of CDDP administration, seems important in order to apply this regimen for head and neck cancer patients safely. The schedule of CDDP administration should be changes depending on the renal and bone marrow function of patients. In order to evaluate the efficacy of UFT as adjuvant chemotherapy, UFT was administered p.o. to patients with maxillary sinus carcinoma for more than one year after definitive treatment with surgery or radiotherapy. Fifteen patients with UFT adjuvant chemotherapy showed significantly better survival rates than patients without adjuvant chemotherapy. We also studied adjuvant chemotherapy with CBDCA and FT for patients with advanced head and neck cancer. Administration with UFT (600 mg/day) from day 1 to day 14 with CBDCA 350 mg/m2 at day 7 was repeated more than twice. This regimen showed low toxicity and better survival for nasopharyngeal cancer patients. More clinical trials with this regimen for adjuvant chemotherapy are needed.     

Induction of gene expression of antibacterial proteins by chitin oligomers in the silkworm, Bombyx mori

A 71-year-old male with advanced gastric carcinoma with paraaortic lymph node metastases underwent distal gastrectomy. Cisplatin (CDDP) 50 mg/body was administered intravenously (i.v.) on day 1 followed by the administration of 5-fluorouracil 500 mg/body/day i.v. on day 2 through day 7. After two courses of this regimen, further enlargement of paraaortic lymph nodes was revealed by CT scan, and chemotherapy was suspended. Multiple liver and lung metastases were diagnosed 6 months after initial diagnosis, and mitomycin C (MMC) 10 mg/body i.v. was administered on day 1 followed by CDDP 50 mg/body i.v. on day 2. After three courses of this regimen, partial response of the liver metastases and complete response of the lung metastases were observed, and the general condition was markedly improved without any adverse effect except slight nausea. Though the patient died of brain metastases one year after initial diagnosis, the combination chemotherapy with MMC and CDDP was nevertheless thought to improve his quality of life.     

Phosphatidyl serine-dependent antiprothrombin antibody is exclusive to patients with lupus anticoagulant

In attempt to develop a new chemotherapeutic regimen including carboplatin (CBDCA), epirubicin (EPI), and VP-16 in extensive small cell lung cancer, with a higher dose intensity compared with previous experience of our group, we determined the maximum tolerated dose (MTD) of VP-16 when administered in association with CBDCA (300 mg/ m2, i.v., day 1) and EPI (75 mg/m2, i.v., day 1), recycling chemotherapy every 3 weeks, with the support of granulocyte-colony-stimulating factor (G-CSF). A total of 15 patients received three dose levels of VP-16 (mg/m2, i.v., daily on days 1-3): 100 (three patients), 120 (six), and 140 (six). G-CSF was administered subcutaneously at the dose of 5 micrograms/kg/day on days 6-15 of each chemotherapy course. The MTD was established at 140 mg/m2 and myelotoxicity, grade 4 neutropenia with death for sepsis in one case and grade 3 thrombocytopenia in three cases, was dose limiting. The recommended dose of VP-16 for a phase II study is 140 mg/m2.     

An early phase II trial combining cisplatin and carboplatin in advanced non-small cell lung cancer

We conducted an early phase II trial in advanced non-small cell lung cancer (NSCLC) to evaluate response efficacy of a combination of Cisplatin (CDDP) and Carboplatin (CBDCA). The twenty-six patients in the study had had no previous treatment. They received a sequential administration of 300 mg/m2 CBDCA and 80 mg/m2 CDDP with approximately 3,500 ml of hydration on day 1 every 4 weeks. All patients were evaluable for response and toxicity. Ten (38.5%) of all assessable patients achieved a partial response (95% confidence interval, 19.8-57.2%). Response rates for patients with stage III A, III B and IV- disease were 40.0 (2/5), 70.0 (7/10) and 9.1% (1/11), respectively. Response rates for patients with squamous cell carcinoma, adenocarcinoma and large cell carcinoma were 35.7 (5/14), 45.5 (5/11) and 0.0% (0/1), respectively. The median survival time (MST) of all patients was 11 months. The MST for patients with stage III disease was 14 months; for those with stage IV disease it was 7 months. The MST for responding patients was 15 months and for not responding patients 5 months. Major toxicities were hematologic and gastrointestinal, and the dose-limiting factor was thrombocytopenia. This combination chemotherapy was effective against NSCLC with tolerable toxicities. Further trials are warranted to determine the efficacy of the combination chemotherapy.     

Microfibrils: neglected components of pressure-bearing tendons

This is a report of 45-year-old man with advanced nonseminomatous germ cell tumor (stage IIIB2: embryonal carcinoma, yolk sac tumor, seminoma), who had relapse after PVB (cisplatin, vinblastine, bleomycin) chemotherapy. Peripheral blood stem cells (PBSCs) were taken by two consecutive apheresis using a CS-3000 blood separator after high-dose chemotherapy of cytarabine and mitoxantrone. In total, 6.4 x 10(5)/kg of granulocytic cells (CFU-GM) was collected. He was treated with ultra high-dose chemotherapy consisting of carboplatin (800 mg/m2), etoposide (1,000 mg/m2) and cyclophosphamide (100 mg/kg) from day 1, followed by peripheral blood stem cell autotransplantation (PBSCT) on day 9. We transfused 2.4 x 10(5)/kg CFU-GM, which was enough number of stem cells for safe PBSCT. No serious side effects or complications were encountered. The patient achieved partial remission for more than two months. However, he died of respiratory dysfunction caused by metastatic lung cancer 5 months later. It was thought that ultra high-dose chemotherapy with PBSCT might be a new therapy for refractory testicular cancer.     

Comparative bioavailability of two oral formulations of ipriflavone in healthy volunteers at steady-state. Evaluation of two different dosage schemes

Because of the relative lack of overlapping toxicity, carboplatin (PPL) and cisplatin (CDDP) can be easily combined for treatment of ovarian cancer to increase total platinum dose intensity. Ifosfamide (IFO), one of the most effective single agents in ovarian cancer, has a low hematological toxicity when administered in continuous infusion. From January 1991 to December 1993, 34 patients with advanced ovarian cancer, previously untreated with chemo- or radiotherapy, were enrolled in a phase I-II study with the aim of determining the maximum tolerated dose (MTD) of CDDP (on day 8 of a 28-day cycle) in combination with PPL (300 mg/m2 on day 1) and IFO (4,000 mg/m2/24 h by continuous infusion on day 1). The initial dose level of CDDP was 40 mg/m2, which was continuously increased by 10 mg/m2 up to the MTD defined as one dose level below that inducing dose-limiting toxicity (DLT) in at least two-thirds of treated patients; no dose escalation was allowed in the same patient. Grade 3-4 leukopenia and thrombocytopenia were observed in 54 and 49% of patients, respectively. The DLT was reached at 70 mg/m2 and therefore the dose recommended for the phase II study was 60 mg/m2. Complete (CR) plus partial response was observed in 88% of patients with a 21% pathological CR. With a minimum follow-up of 32 months (median 40 months), median progression-free survival and overall survival were 21 and 39 months, respectively. In conclusion, the combination of CDDP, PPL, and IFO provides an effective regimen for ovarian cancer with an acceptable toxicity profile.     

Successful treatment of pseudomyxoma peritonei using combination chemotherapy of intraperitoneal low-dose CDDP and oral 5'-DFUR administration

We report a case of pseudomyxoma peritonei treated with combination chemotherapy. A 73-year-old woman was diagnosed as having psuedomyxoma peritonei originated from the vermiform appendix. Appendectomy was performed, and 10 mg of MMC was administered intraperitoneally. From day 7, 600 mg/day of 5'-DFUR was orally given for 2 years, and 20 mg of CDDP once a month was intraperitoneally administered seven times. The patient has been doing well with no evidence of tumor recurrence for two years after operation. Combination chemotherapy with CDDP and 5'-DFUR, as a biochemical modulation therapy, has fewer side effects and leads to better quality of life of patients. We recommend a combination chemotherapy with low-dose CDDP and 5'-DFUR for patients in poor general condition.     

MRI of hyperpolarized 3He gas in human paranasal sinuses

Relapsed or refractory adult acute lymphoblastic leukemia (ALL) carries a grave prognosis. The most promising strategy for curing these patients is through re-induction chemotherapy followed by successful allogeneic transplant. We studied a new high-dose induction regimen in order to improve the outcome for these patients. Eighteen adult patients with relapsed/refractory ALL were treated on a phase I study of high-dose cytarabine combined with a single escalating dose of idarubicin. Five patients had primary refractory disease and 13 were treated in refractory relapse. Nine patients (50%) had Ph+ ALL. The induction regimen was cytarabine 3 g/m2/day intravenously days 1-5 and idarubicin as a single intravenous dose on day 3. G-CSF 5 microg/kg subcutaneously every 12 h was started on day 7. The initial idarubicin dose was 20 mg/m2 with dose escalations of 10 mg m2. Cohorts of three patients were treated at each idarubicin dose level. Unacceptable toxicity was encountered at 50 mg/m2 with one death from infection and one death from cardiotoxicity in a patient with significant prior anthracycline exposure. There were no instances of grade 4 non-hematologic toxicity encountered at idarubicin doses of 20 mg/m2, 30 mg/m2, or 40 mg/m2. The data suggest a dose-response relationship for increasing doses of idarubicin with 0/3 complete responses (CR) at 20 mg/m2, 1/3 CR at 30 mg/m2, and 7/12 (58%) CR at idarubicin doses > or = 40 mg/m2. We conclude that concomitant administration of cytarabine 3 g/m2/day x 5 and high-dose idarubicin at 40 mg/m2 as a single dose on day 3 can be administered safely to patients with refractory and relapsed ALL.     

A case of advanced gastric carcinoma with disappearance of cancer cells by neoadjuvant chemotherapy

A 74-year-old man was diagnosed by preoperative X-ray and endoscopy with biopsy as having type 2 advanced gastric carcinoma (poorly differentiated adenocarcinoma) in the antrum. CT scan revealed swelling of the paraaortic lymph nodes, which was considered to be metastasis from the gastric carcinoma. As the cancer was judged to be stage IV and too advanced for a curative surgical resection, a neoadjuvant chemotherapy was initiated. One course of the regimen consisted of 10 mg of CDDP (day 1-5, drip) and 300 mg of UFT (day 1-7, oral), and the patient underwent the regimen three times in succession. After the chemotherapy, the swelling of para-aortic lymph nodes disappeared on CT scan. A distal gastrectomy with D2 lymph nodes dissection and sampling of the para-aortic lymph nodes was performed. Histopathological examination revealed that the cancer cells had completely vanished both in the primary tumor and lymph nodes. The effect of this neoadjuvant chemotherapy was judged to be Grade 3 histopathologically.     

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.     

Combination chemotherapy with cis-platinum and ifosfamide for hormone unresponsive prostate cancer

PURPOSE: There is no effective therapy against hormone refractory prostate cancer. This led us to evaluate the effectiveness and toxicity of cis-platinum (CDDP) and ifosfamide (IFM) combination chemotherapy in the patients with hormone-unresponsive carcinoma of the prostate. METHODS: Patients with hormone-unresponsive prostate cancer were scheduled to receive CDDP 70 mg/m2 intravenously on day 1 and IFM 1.2 g/m2/day intravenously on day 1 through day 5 of 28-day cycle. RESULTS: Twenty seven patients with hormone unresponsive prostate cancer were enrolled onto this trial. Of these patients, seven (26%) demonstrated a partial objective response (PR), and ten (37%) a stable disease (ST). The response duration of PR cases lasted from 6 to 49 months with a median of 16 months and the response duration of PR + ST cases lasted from 3 to 36 months with a median of 10 months. Subjective improvement was obtained in 11 patients (41%). Survival duration of all cases were 4 to 89 months with a median of 23 months and probabilities of survival at 3 years and 5 years were 36% and 24%, respectively. The toxicity of this treatment was mostly mild to moderate, anemia (96%), leukocytopenia (89%), anorexia (81%), alopecia (67%), thrombocytopenia (44%), hematuria (38%), renal dysfunction (19%) and liver dysfunction (7%) were noticed. Severe toxicity was observed in two cases, one acute renal failure and one endotoxin shock. CONCLUSION: We conclude that CDDP and IFM combination chemotherapy was active regimen for hormone unresponsive prostate cancer.     

Allergenic crossreactivities. Pollens and vegetable foods

The effects of interleukin-11 (IL-11) which stimulates megakaryopoiesis and thrombopoiesis and/or stem cell factor (SCF) which stimulates multiple lineage cells in the peripheral blood by an increase in marrow cellularity on hematopoietic suppression in carboplatin (CBDCA)-treated rats were determined. CBDCA was administered to rats at a dose of 35 mg/kg as a single intraperitoneal bolus on day 0. IL-11 (20 micrograms/day) was given subcutaneously for 10 days from day 5 after CBDCA treatment. IL-11 ameliorated the suppression of hematopoiesis in rats treated with CBDCA. Especially, the production of the platelets was stimulated by IL-11 more markedly than that of cells of other lineages. However, the combination of SCF and IL-11 intensified the CBDCA-induced suppression of hematopoiesis. These findings may be helpful in the design of future therapies to prevent or treat thrombocytopenia induced by chemotherapy.     

Scaling of movement velocity: a measure of neuromotor retardation in individuals with psychopathology

The combination of ifosfamide, carboplatin and etoposide (modified ICE), was evaluated for its toxicity and activity in relapsed or refractory aggressive non-Hodgkin's lymphoma. Twenty patients, 14-69 years of age, with relapsed (19 cases) or refractory (one case) aggressive non-Hodgkin's lymphoma were treated with modified ICE therapy, consisting of ifosfamide 6 g/m2 (1.2 g/m2 day 1-5), carboplatin 400 mg/m2 (day 1) and etoposide 500 mg/m2 (100 mg/m2 day 1-5). The regimen was repeated at approximately 28-day intervals. All patients had undergone a doxorubicin-containing regimen before modified ICE therapy. Median total dose of previously received doxorubicin was 406 mg/m2 (range: 200-825 mg/m2). The median interval from diagnosis to modified ICE therapy was 9.4 months (range: 3.6-121 months). Two patients achieved CR and five achieved PR out of 16 patients with measurable lesions (response rate 43.8%; 95% confidence interval 19.0-68.6%). Median overall survival was 227 days (range: 41-552 days) from the start of modified ICE therapy. Myelosuppression was the most serious toxicity, namely 16 patients (80%) and 11 patients (55%) showed grade 4 neutropenia and grade 4 thrombocytopenia after the first course, respectively. Modified ICE therapy might be an active regimen with acceptable toxicity as a salvage chemotherapy in aggressive non-Hodgkin's lymphoma.     

Hepatic arterial infusion chemotherapy (HAI) for advanced hepatocellular carcinoma inefficacious with transcatheter arterial embolization (TAE)

For 6 patients with advanced hepatocellular carcinoma (HCC) in whom TAE was inefficacious, we tried hepatic arterial infusion chemotherapy. 5-FU 500 mg/day + CDDP 10 mg/day was administered during 5 days. The AFP level was decreased for 4 patients, and 2 patients showed a partial response in CT image. These 2 patients have been alive over 22 and 18 months, respectively. These results suggest that 5-FU + CDDP HAI might be a useful treatment of HCC inefficacious with TAE.     

Paclitaxel with mitoxantrone, fluorouracil, and high-dose leucovorin in the treatment of metastatic breast cancer: a phase II trial

PURPOSE: Paclitaxel is a highly active single agent in the treatment of breast cancer. However, its optimal incorporation into combination regimens awaits definition. In this phase II study, we added paclitaxel, administered by 1-hour infusion, to a previously described combination regimen that included mitoxantrone, fluorouracil (5-FU), and high-dose leucovorin (NFL). PATIENTS AND METHODS: Forty-six patients with metastatic breast cancer received the following regimen as first- or second-line treatment: paclitaxel 135 mg/m2 by 1-hour intravenous (i.v.) infusion on day 1, mitoxantrone 10 mg/m2 by i.v. bolus on day 1, 5-FU 350 mg2/m by i.v. bolus on days 1, 2, and 3, and leucovorin 300 mg i.v. over 30 to 60 minutes immediately preceding 5-FU on days 1, 2, and 3. Courses were administered at 3-week intervals for a total of eight courses in responding patients. RESULTS: Twenty-three of 45 assessable patients (51%) had major responses. Previous chemotherapy, and in particular previous treatment with doxorubicin, did not affect response rate. The median response duration was 7.5 months. Myelosuppression was moderately severe, with 76% of courses resulting in grade 3 or 4 leukopenia. Hospitalization for treatment of fever during neutropenia was required in 13% of courses, and two patients died as a result of sepsis. Two patients developed severe congestive heart failure after a large cumulative anthracycline dose. CONCLUSION: This combination regimen was active as first- or second-line therapy for metastatic breast cancer, although its activity compared with other combination regimens or with paclitaxel alone is unclear. Myelosuppression was more severe than anticipated based on previous results with the NFL regimen or with paclitaxel administered at this dose and schedule as a single agent. The infrequent development of cardiotoxicity in these patients suggests that the paclitaxel/mitoxantrone combination may not share the problems previously reported with the paclitaxel/doxorubicin combination.     

A case of relapsed thymic carcinoma that responded remarkably to chemotherapy with CPT-11

A chemotherapeutic protocol for advanced thymic carcinoma has not been established as yet. We described a case of advanced and relapsed thymic carcinoma that responded remarkably to subsequent chemotherapy with CPT-11. A 61-year-old man was admitted to our hospital because of facial edema and general fatigue. Chest X-ray and CT scan showed anterior mediastinal tumor which involved large vessels and pericardium. CT guided needle biopsy yielded a diagnosis of squamous cell type of thymic carcinoma. The patient was initially treated with ADOC (ADM, CDDP, VCR, CPA) chemotherapy and had successfully controlled for six months. However, the mediastinal tumor recurred and radiotherapy and nedaplatin plus ETP therapy were not effective. Then, CPT-11 chemotherapy (80 mg/m2, 2 weeks) was performed. The patient showed a partial response after two courses of CPT-11 chemotherapy. This case suggests that CPT-11 is a useful chemotherapeutic agent for advanced thymic carcinoma.     

Bone mass in middle-aged osteoporotic men and their relatives: familial effect

Combination chemotherapy with continuous infusion 5-FU, 350 mg/m2/day and low-dose CDDP between 5 to 10 mg/body/day (day 1-5) was evaluated in 46 patients with unresectable gastric (34), colorectal (10) and biliary tract (2) carcinoma. This regimen was repeated for 4 weeks. The overall response rate was 45.7% (21/46), but the resectable rate was only 10.9% (5/46). Toxic response (> grade 2) was 22% (10/46). After chemotherapy, the patients preserved good performance status and quality of life. Median survival time was about 11 months, and there was no significant difference between CR or PR cases and NC one. Survival time of patients correlated not to the reduction rate of tumor but to conditions of hosts (e.g., performance status, quality of life). These results suggested that this therapy is an effective palliative chemotherapy for patients with unresectable gastrointestinal carcinoma.     

Mineral waters: instead of soap or better than soap?

Prolonged oral etoposide is an active regimen in small and nonsmall cell carcinoma of the lung, carcinomas of the breast and ovary, germ cell tumors, and in lymphoma. A Phase II trial was conducted by the Gynecologic Oncology Group to determine its activity in endometrial carcinoma. Twenty-six patients with advanced or recurrent endometrial carcinoma were entered into study; one patient was ineligible because of an incorrect cell type. The remaining eligible patients were treated with etoposide at a starting dose of 50 mg/m2/day (30 mg/m2/day with prior radiotherapy) for 21 days. Based on hematologic toxicity, a dose escalation to a maximum dose of 60 mg/m2/day was prescribed. Twenty-two patients were evaluable for response and 25 were evaluable for toxicity. Fourteen had received prior radiotherapy and 24 had received prior chemotherapy. A median of two courses were given (range, 1-10). Grade 3 or 4 leukopenia occurring in 52% was the most common complication (grade 3, 36%; grade 4, 16%). Grade 4 thrombocytopenia occurred in 16% of patients. There were no objective responses including four patients with serous papillary carcinoma. This regimen is not significantly active as second-line therapy in endometrial carcinoma.     

Combination chemotherapy of continuous infusion 5-fluorouracil and daily low-dose cisplatin in advanced gastrointestinal and lung adenocarcinoma

Continuous intravenous infusion (c.v.i.) of 5-fluorouracil (5-FU) plus daily low-dose cisplatin (CDDP) was evaluated in 45 patients with advanced and recurrent unresected colorectal, lung, gastric and pancreatic adenocarcinoma. 5-FU was given at a dose of 320 mg/m2/day, c.v.i. for 4 weeks, and CDDP between 3.5 to 7 mg/m2/day, infused for one hour five times a week for 4 weeks. Patients received 1 to 3 cycles of treatment (average 1.5 cycle). Pancreatic cancer cases needed longer treatment periods (2.25 cycles). The response rate of colorectal cancer cases was 57.7% (15/26), pancreas cancer 40%, gastric cancer 62.5%, and lung cancer 66.7%. The overall response rate was 57.8%. No severe side effects occurred in any of these cases. These data indicate that this combination 5-FU + daily low-dose CDDP chemotherapy is effective in the treatment of advanced gastrointestinal and lung adenocarcinoma.     

Aortic dissection and Turner''s syndrome: case report and review of the literature

Combination chemotherapy with 5-FU and CDDP was given to two patients with obstructive jaundice due to intra-abdominal lymph-node metastases of advanced and recurrent gastric cancer. One patient was a primary case associated with lymph-node metastases of portal fissure and periaorta, and the other was a recurrent case associated with lymph-node metastases of hepatoduodenal ligament and periaorta. The regimen consisted of 5-FU 1,000 mg/ m2 (day 1-5, continuous infusion) and CDDP 100 mg/m2 (day 3, 1 hr drip infusion). The interval was from the 6th to 21st day. The response to chemotherapy showed shrinking of intra-abdominal lymph-nodes and reopening of the biliary tract. The patients could be discharged from the hospital without PTBD tube and enjoyed a better quality of life (QOL). This therapy is thought to be effective against obstructive jaundice due to intra-abdominal lymph-node metastases of advanced and recurrent gastric cancer.
