Phase II trial of paclitaxel, ifosfamide, and cisplatin in patients with recurrent head and neck squamous cell carcinoma

PURPOSE: To assess the activity and toxicity profile of combined taxol (paclitaxel), ifosfamide, and platinum (cisplatin) (TIP) in patients with recurrent or metastatic squamous cell carcinoma (SCC) of the head and neck. PATIENTS AND METHODS: Recurrent or metastatic head and neck SCC patients received paclitaxel 175 mg/m2 in a 3-hour infusion on day 1; ifosfamide 1,000 mg/m2 in a 2-hour infusion on days 1 through 3; mesna 600 mg/m2 on days 1 through 3; and cisplatin 60 mg/m2 on day 1, repeated every 3 to 4 weeks. All were premedicated with dexamethasone, diphenhydramine, and cimetidine. Prophylactic hematopoietic growth factors were not permitted. RESULTS: Fifty-two patients were assessable for response and toxicity; 53 for survival (local-regional recurrence alone in 57% and distant metastasis with or without local-regional recurrence in 43%). Overall response rate was 58% (30 of 52) of patients; complete response rate was 17% (nine of 52) of patients, with six complete responses that continued for a median 15.7+ months. Median follow-up of all patients was 17.7 months. Median survival was 8.8 months (95% confidence interval [CI] 8.1 to 17.5 months). Toxicity was relatively well tolerated and caused no deaths. The most frequent moderate-to-severe toxicity (90% of patients) was transient grades 3 to 4 neutropenia; neutropenic fever occurred in 27%. Grade 3 peripheral neuropathy occurred in three patients, none had grade 4. Grade 3 mucositis occurred in only one patient, none had grade 4. CONCLUSION: TIP had major activity in this setting, with a 58% objective response rate, 17% complete response rate, durable complete responses (six of nine persisting), and relatively well-tolerated toxicity, with no toxic deaths. The activity of TIP, a novel taxol-cisplatin-based regimen, in recurrent or metastatic head and neck SCC should be confirmed in a phase III trial.     

5-Fluorouracil dose intensification and granulocyte-macrophage colony-stimulating factor in cisplatin-based chemotherapy for relapsed squamous cell carcinoma of the head and neck: a phase II study

We reviewed the clinical record of all patients admitted to Saga Medical School Hospital during the most recent 10 years and found that 17 (0.03%) were diagnosed as having necrotizing fasciitis. Bacteriological examination demonstrated that Vibrio vulnificus was the pathogen responsible in five patients (29%). The disease caused by V. vulnificus occurred in the warmer half of the year. All of the patients had underlying chronic liver dysfunction, and three of them had previously consumed raw seafood. In these patients, the predominant skin lesions were oedema and subcutaneous bleeding, such as ecchymosis and purpura, while superficial necrosis was not recognized. Three patients died of systemic complications. By contrast, all of the five patients with necrotizing fasciitis caused by Streptococcus pyogenes had the disorder in winter, and only one of them had chronic liver dysfunction. In skin lesions, subcutaneous bleeding was rare but necrosis was seen often. Despite the high incidence of systemic complications, no patients with streptococcal necrotizing fasciitis died. These findings suggest that the clinical features of necrotizing fasciitis caused by V. vulnificus are different from those of necrotizing fasciitis caused by classical pathogens, and that the two should be differentiated as early as possible to improve the prognosis.     

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.     

Accelerated hyperfractionated radiation therapy and concurrent 5-fluorouracil/cisplatin chemotherapy for locoregional squamous cell carcinoma of the thoracic esophagus: a phase II study

PURPOSE: To improve the poor prognosis of patients with locoregional esophageal squamous cell cancer, we used concurrent accelerated hyperfractionated radiation therapy (ACC HFX RT) and chemotherapy (CHT). MATERIAL AND METHODS: Between January 1988 and June 1993, 28 patients were treated with ACC HFX RT with 1.5 Gy twice daily, to a total dose of 54 Gy concurrently with 5-fluorouracil (5-FU) (300 mg/m2, days 1-5) and cisplatin (CDDP) (10 mg/m2, days 1-5), both given during weeks 1 and 4 of the ACC HFX RT course. Following the ACC HFX RT/CHT, two additional courses of 5-FU (500 mg/m2, days 1-5) and CDDP (20 mg/m2, days 1-5) were both given during weeks 7 and 10. The median age and Eastern Cooperative Oncology Group performance status were 62 and 1, respectively. The American Joint Committee on Cancer (AJCC) stage was I in 12 patients, II in 10, and III in 6. RESULTS: The median survival time was 26 months, and the 5-year survival rate was 29%. The rates at 5 years for freedom from relapse, locoregional recurrence, and distant metastasis were 29%, 61%, and 45%, respectively. Univariate analysis revealed that performance status, stage, weight loss, tumor length, and tumor location influenced survival, while age and sex did not. The most frequent acute high-grade (3 or 4) toxicities were esophagitis and leukopenia, seen in 50% and 39% of patients, respectively. Late high-grade toxicity was infrequent. There were no treatment-related deaths. CONCLUSION: The results of this study compare favorably with those of previous studies, albeit of relatively high incidence of acute high-grade toxicity. Further studies are warranted to compare its efficacy with other approaches.     

Phase II study of weekly high-dose cisplatin for six cycles in patients with locally advanced squamous cell carcinoma of the head and neck

Seven children, six boys and a girl, aged from 2 to 15 years with proven myelofibrosis are reported. The clinical presentation in each of them was more or less similar with weight loss, moderate or low-grade fever, and abdominal distension with pain or discomfort for some months. They had hepatosplenomegaly. The spleens, enlarged to more than 6 cm below the costal margin, were smooth, firm and not tender. There was a variable degree of generalized lymphadenopathy. They were diagnosed as myelofibrosis associated with tuberculosis. The clinical response to anti-tuberculous chemotherapy was remarkable. Extensive search should be made for evidence of tuberculosis in children presenting with myelofibrosis.     

Alloantigen gene therapy for squamous cell carcinoma of the head and neck: results of a phase-1 trial

OBJECTIVE: To determine the safety and efficacy of an immunogenic gene therapy using a drug designed to produce expression of a foreign class I major histocompatibility complex protein in patients with head and neck cancer. DESIGN: Phase 1 prospective clinical trial. SETTING: Academic medical setting. PATIENTS: Nine patients with advanced head and neck squamous cell carcinoma who had failed conventional therapy and did not express HLA-B7, a class I major histocompatibility complex protein. INTERVENTION: Patients were treated with Allovectin-7 (Vical Inc, San Diego, Calif) by direct intratumoral injection. Allovectin-7 contains a plasmid complementary DNA complexed with a cationic lipid, which results in expression of HLA-B7. MAIN OUTCOME MEASURES: Patients were assessed for any toxic effects and for any change in tumor volume. Biopsy specimens obtained before and after therapy were evaluated by immunohistochemistry to detect HLA-B7 expression and with the terminal deoxynucleotide transferase-mediated deoxyuridine triphosphate-biotin nick end labeling (TUNEL) assay to detect any induction of apoptosis. RESULTS: There were no toxic effects of the gene therapy. In 4 of these 9 patients there was a partial response to treatment, evidenced by a gradual reduction in tumor size. One patient has remained alive for more than 17 months since commencing treatment, with no clinical evidence of disease but with persistent histological evidence of cancer. Analysis of the biopsy specimens from 2 of the patients who responded to therapy demonstrated HLA-B7 expression. The TUNEL assay demonstrated extensive apoptosis in both of these patients, suggesting that this may be the mechanism of tumor reduction. CONCLUSIONS: These data demonstrate the potential efficacy and lack of toxicity of this form of alloantigen gene therapy. A multi-institutional study has been initiated to expand on these findings.     

Radiotherapy and concurrent chemotherapy for the treatment of locally advanced head and neck squamous cell carcinoma

PURPOSE: To determine whether combination 5-fluorouracil, cisplatin, and interferon alfa, an active regimen in advanced esophageal cancer, is efficacious as induction therapy before esophagectomy. MATERIALS AND METHODS: Forty-four patients with potentially resectable esophageal/gastroesophageal junction adenocarcinoma or squamous cell carcinoma were entered into a phase I/II study of this chemotherapeutic regimen and concurrent external-beam radiotherapy before resection. The initial 16 patients were treated with prolonged-infusion 5-fluorouracil (300 mg/m2 on days 1 to 28), cisplatin (20 mg/m2 on days 1 to 5 and 24 to 28), interferon alfa (3 x 10(6) U/m2 intravenously on days 1 to 5 and 24 to 28; subcutaneous injection every other day on days 6 to 23), and radiation (4000 cGy). The subsequent 28 patients were treated over 21 days with two modifications: dose escalation of 5-fluorouracil (250 to 350 mg/m2) and double-fractionated radiotherapy to a total dose of 4500 cGy. RESULTS: Forty-one patients completed chemoradiotherapy and were evaluable for toxicity. Adverse events were substantial but tolerable, and most toxic episodes were hematologic and gastrointestinal. Three patients died, and one patient had progressive disease before resection. Of the 37 patients eligible for curative resection, 36 had all gross tumor removed. Thirty-three (80%) patients had a major pathologic response: 10 (24%) with no residual tumor and 23 with only microscopic residual tumor. Median survival for all patients was 27 months and for responders was 36 months. CONCLUSIONS: This combination regimen is active but yields results similar to those of other chemoradiotherapy phase II trials; therefore, the contribution of interferon alfa to treatment efficacy remains uncertain. The true worth of preoperative chemoradiotherapy is unknown pending results of phase III trials.     

An EORTC-ECSG phase II study of vinorelbine in patients with recurrent and/or metastatic squamous cell carcinoma of the head and neck

BACKGROUND: Vinorelbine is an active drug in the treatment of lung and breast cancers and has a favorable toxicity profile. Many clinical trials have demonstrated its antitumor activity in other tumor types including squamous cell carcinoma of the head and neck (SCCHN). We investigated the efficacy and tolerability of vinorelbine in patients with recurrent and/or metastatic SCCHN, previously untreated by chemotherapy. PATIENTS AND METHODS: Seventy-one patients with locoregional recurrent and/or metastatic SCCHN were treated with vinorelbine at a dose of 30 mg/m2/week i.v. by short-duration infusion on an out-patient basis. Doses were adjusted according to tolerance. RESULTS: Two complete and seven partial responses were observed among 56 evaluable patients, yielding a response rate of 16% (95% confidence interval (CI): 8%-28%). The overall response rate of all eligible patients (63) was 14%. The responses were seen in recurrent tumors, lymph nodes and in lung metastases, and their median duration was 19 weeks (12-63). The main toxicity, severe and reversible neutropenia (grade 3-4) occurred in 53% of the 69 evaluable (for toxicity) patients. Twelve patients developed severe bronchopulmonary infections, which caused two early deaths. Constipation was observed in 31 patients (45%). Other gastrointestinal toxicities, asthenia, acute pain syndrome and peripheral sensory neuropathy, were mild to moderate. The median number of treatments was seven cycles and the median relative dose intensity of vinorelbine was 85% (25.5 mg/m2/week). CONCLUSIONS: Vinorelbine is an active drug, with acceptable toxicity, in recurrent and/or metastatic SCCHN, at the dose and schedule administered in the present study. Further evaluation in association with other agents and/or radiotherapy is warranted.     

Phase II trial of cisplatin and gemcitabine in advanced squamous-cell carcinoma of the head and neck

BACKGROUND: To evaluate the toxicity profile and efficacy of cisplatin combined with gemcitabine in patients with irresectable locally recurrent or metastatic squamous cell carcinoma of the head and neck. PATIENTS AND METHODS: Gemcitabine was given at a dose of 800 mg/m2 on days 1, 8 and 15, plus cisplatin at a dose of 50 mg/m2 on days 1 and 8; every four weeks. RESULTS: Twenty-four patients with a median age of 59 years (range 42-74) were included. All patients were evaluable for toxicity and 22 patients were assessable for response. Eleven cases had advanced recurrent locoregional disease while 13 patients had metastatic disease. One CR (4.7%) and four PR (18%) were observed, for an overall response rate of 22.7% (95% CI: 8%-42%). The main toxicity was hematological: neutropenia grade 3-4 in 28% of the cycles and thrombocytopenia grade 3-4 in 16%. The most significant non-hematological toxicity was asthenia grade 2-3 in 24% of the cycles. CONCLUSIONS: This cisplatin plus gemcitabine combination schedule has a favourable toxicity profile with a discrete activity in patients with locally recurrent or metastatic squamous-cell carcinoma of the head and neck.     

Final report of a phase II evaluation of paclitaxel in patients with advanced squamous cell carcinoma of the head and neck: an Eastern Cooperative Oncology Group trial (PA390)

BACKGROUND: A number of single agents have been tested in patients with carcinoma of the head and neck receiving palliative treatment. In general, 15-30% of patients achieve a partial response lasting 3-4 months. Treatment has not been shown to alter survival rates. It is clear that new drugs with potentially greater activity need to be identified. For this purpose, the Eastern Cooperative Oncology Group conducted a Phase II evaluation of paclitaxel. METHODS: Patients with recurrent, metastatic, or locally advanced, incurable squamous cell carcinoma of the head and neck were eligible. The dose and schedule tested was the maximum tolerable dose of 250 mg/m2 determined from Phase I trials using a 24-hour infusion schedule and granulocyte-colony stimulating factor support. Courses were given at 3-week intervals until progression of disease was documented. Dose modifications were specified for hematologic toxicity and for neurotoxicity. RESULTS: Thirty-four patients were registered on study and 30 were eligible. Severe or life-threatening granulocytopenia was the most frequent toxicity observed, occurring in 91% of patients. Prior to response evaluation, one patient died of sepsis and one died of a myocardial infarct. Response was observed in 40% of eligible patients (4 complete and 8 partial responses). The median duration of response was 4.5 months (range, 2-20 months), with a median survival of 9.2 months and a 1-year survival rate of 33%. CONCLUSIONS: These results indicate that paclitaxel is an active agent for the treatment of squamous cell carcinoma of the head and neck. Studies evaluating alternative infusion schedules and combination regimens currently are underway.     

Microsatellite instability in squamous cell carcinoma of the head and neck

Genomic instability or microsatellite instability (MI) in simple repeated sequences was initially recognised in colonic carcinomas and subsequently in other tumours. MI has been associated with mutations in genes concerned with replication and DNA repair. We investigated 34 microsatellite markers in squamous cell carcinoma of the head and neck (SCCHN). Fifty-six tumours, were studied, of which 25 were investigated with ten or more microsatellite markers. In this study we consider two or more microsatellite alterations in a tumour to be diagnostic of MI. We demonstrated that 7/25 (28%) of the tumours had MI at two or more loci and three of these tumours exhibited evidence of 20 or more loci with MI. No correlations were found between MI and previous treatment, site, histological differentiation, positive nodes at pathology, a history of alcohol intake or survival. MI has been demonstrated in T1N0 stage tumours, indicating that these changes may occur early in the disease process. A negative correlation was found between MI and a history of smoking (P = 0.02). Two or more markers of MI were found in three of four non-smokers compared with one of 13 in the smoking group of patients, which suggests a novel mechanism of carcinogenesis in non-smokers.     

Expression of galectins in head and neck squamous cell carcinoma

BACKGROUND: Galectins are carbohydrate-binding proteins thought to be important for cell growth and differentiation, whose expression is altered in some tumors with aggressive phenotype. Our objective was to evaluate the expression of galectins in head and neck squamous cell carcinoma (HNSCC). METHODS: Fourteen HNSCC cell lines and four primary tumor specimens were evaluated using immunoblotting, and immunohistochemical analysis was performed on 35 primary HNSCCs. RESULTS: Galectin-1 and galectin-3 were expressed in most HNSCC cell lines and primary tumor specimens. Galectin-1 was detected in the basal layer of normal adjacent mucosa, in connective tissue stroma, and at the periphery of invasive tumor islands. Galectin-3 localized to superficial mucosal layers, and adjacent to keratin pearls in invasive carcinoma. CONCLUSIONS: Galectins are manifested in HNSCC tumors and are localized to the cell surface, where they may participate in cellular interactions. The expression pattern of galectins appears to be associated with degree of squamous differentiation, suggesting a potential role for galectins as biologic and differentiation markers in HNSCC.     

Evaluation of topotecan in patients with recurrent for metastatic squamous cell carcinoma of the head and neck. A phase II Southwest Oncology Group study

A case of inveterate dislocation of the knee treated by the authors is presented. Due to initial circumstances inclusive of polytrauma and life threatening condition of the patient the dislocation was untreated for 8 weeks. Surgical reduction supplemented with capsule ligamentoplasty despite development of multiple periarticular calcifications allowed for regaining sufficient mobility and function of the joint.     

Treatment of patients with transitional-cell carcinoma of the urothelial tract with ifosfamide, paclitaxel, and cisplatin: a phase II trial

PURPOSE: A phase II trial of ifosfamide, paclitaxel, and cisplatin (ITP) was conducted in previously untreated patients with advanced transitional-cell carcinoma (TCC) to assess its efficacy and toxicity. PATIENTS AND METHODS: Thirty patients with metastatic or unresectable TCC were treated with ifosfamide 1.5 g/m2/d for 3 days with paclitaxel 200 mg/m2 over 3 hours and cisplatin 70 mg/m2 on day 1 of each 28-day treatment cycle. Therapy was continued for a maximum of six cycles. Prophylactic hematopoietic growth factor (recombinant human granulocyte colony-stimulating factor [rhG-CSF]) was given on days 6 to 17 of each cycle. RESULTS: Twenty-three of 29 assessable patients (79%; 95% confidence interval [CI], 60% to 92%) demonstrated a major response (six complete [CR] and 17 partial [PR]) with response durations that ranged from 5 to 24+ months. Five patients with T4 bladder primary tumors had a major response, two with pathologic CR. At a median follow-up duration of 17.9 months, nine (31%) patients remain disease-free (range, 10+ to 24+). Hematologic toxicity included anemia, thrombocytopenia, and neutropenia; febrile neutropenia was observed in 17% of patients and 4% of cycles. No grade 4 nonhematologic toxicity was observed. Grade 3 nonhematologic toxicity included alopecia, allergy (3%), renal insufficiency (13%), and neuropathy (10%). Dose reductions or drug omissions were necessary for adverse events in seven (23%) patients. CONCLUSION: ITP is an active, well-tolerated regimen in previously untreated patients with TCC of the urothelial tract. Further study of this regimen in patients with both TCC and non-transitional-cell urothelial tumors is ongoing.     

Radiologic diagnosis and staging of head and neck squamous cell carcinoma

The predominant extracranial head and neck cancer in adults is squamous cell carcinoma. The purpose of this article is to discuss the radiographic evaluation of these patients with computed tomography (CT) or magnetic resonance (MR) imaging prior to therapeutic intervention. Specific focus is given to the efficacy of CT and MR imaging, as an adjunct to clinical staging, for evaluation of the primary tumor, and metastatic adenopathy. MR imaging, because of its improved soft tissue contrast and multiplanar capability, is probably superior to CT for evaluation of the primary tumor in patients with squamous cell carcinoma. CT, however, remains the gold standard for identifying metastatic adenopathy and in most institutions remains the study of choice for evaluating this patient population.     

A phase II trial of 5-fluorouracil, leucovorin, and carboplatin in patients with unresectable biliary tree carcinoma

BACKGROUND: Unresectable adenocarcinoma of the biliary tree are associated with a very poor prognosis. 5-fluorouracil (5-FU) combination regimens have produced objective response rates in approximately 10-20% of patients. Leucovorin increases the selective cytotoxicity of 5-FU. There also are encouraging reports of carboplatin in combination with 5-FU in other gastrointestinal tract malignancies. METHODS: Fourteen consecutive eligible patients were treated with a combination of carboplatin, 300 mg/m2, intravenously (i.v.) on Day 1 only and 5-FU, 400 mg/m2, i.v. with leucovorin, 25 mg/m2, i.v. on Days 1-4. All patients were required to have a histologically confirmed diagnosis and measurable disease. Patients were evaluated for response, survival, and toxicity. RESULTS: A total of 48 cycles of therapy were delivered. The median survival was 5 months. One patient achieved complete remission and two others partial remission, for a total response rate of 21.4%. Four additional patients had stable disease for a median duration of 4 months. The therapy was well tolerated, with moderate myelosuppression as the main dose-limiting toxicity. CONCLUSIONS: The current combination regimen of leucovorin-modulated 5-FU with carboplatin is well tolerated with appropriate supportive care, produces significant objective responses in 21% of patients with biliary tree carcinoma, and should be considered for the treatment of this disease.     

Neo-adjuvant chemotherapy +/- immunotherapy with s.c. IL 2 in advanced squamous cell carcinoma of the head and neck: a pilot study

We carried out a pilot nonrandomized phase II study to compare the neo-adjuvant chemotherapic regimen with cisplatin, 5-FU and vinorelbine with the same combination plus s.c. IL 2 in advanced head and neck squamous cell carcinoma (HNSCC). The primary goals of the trial were to evaluate the feasibility and response rates of the two regimens. The study design consisted of a patient's assignment to either of the two following arms: Arm A: Cisplatin 80 mg/m2 i.v. on day 1; 5-FU 600 mg/m2 i.v. on days 2-5; and vinorelbine 20 mg/m2 i.v. on days 2 and 8, Arm B: the same chemotherapic regimen plus recombinant IL 2 (Proleukin, Eurocetus) 9 MIU s.c. daily from day 9 to 13 and from day 16 to 20 for every cycle. From March 1993 to November 1993 twenty three patients with Stage III-IV HNSCC were enrolled in the study. Patients could be evaluated for response to treatment if they had received at least 2 complete cycles of therapy. The overall response rate (ORR) was 63% in Arm A and 100% in Arm B. The differences for ORR and CR rates were statistically significant in favor of Arm B. The analysis for each of the three drugs included in the chemotherapy schedule shows that both the actually received average dose-intensity and the actually delivered average cumulative doses/patient were higher for Arm B (chemo-plus IL 2 therapy) (approximately 80% of programmed dose-intensity) than for Arm A (approximately 70% of programmed dose-intensity). Both the actually received average dose-intensity and the actually delivered average cumulative doses/patient for IL 2 were more than 80%. In both arms the most frequent side effects were myelosuppression, phlebitis and electrolyte disturbances. There were 2 toxic deaths, 1 in Arm A and 1 in Arm B, both for hematologic toxicity. Our "pilot" study suggests that the combination of cisplatin, 5-FU, vinorelbine plus IL 2 is a highly active, but rather toxic, neo-adjuvant treatment in advanced HNSCC with very high ORR and CR rates.
