Evaluation of low dose continuous infusion 5-fluorouracil in patients with advanced and recurrent renal cell carcinoma. A Southwest Oncology Group Study

BACKGROUND

The response rate of metastatic renal cell cancer to cytotoxic therapy over the last 10 years has been 5.6%. Low dose continuous 5-fluorouracil (5-FU) has demonstrated efficacy in other cytotoxic refractory tumors, such as pancreas, colorectal, and recurrent breast. The Southwest Oncology Group undertook a Phase II trial of low dose, continuous 5-FU in metastatic renal cell cancer.

METHODS

Sixty-one patients were entered in the study to receive 300 mg 5-FU/m2/day for 7 days via a central venous catheter and external programmable pump. The pump was refilled every 7 days. Pyridoxine (50 mg, orally) was administered prophylactically three times a day.

RESULTS

A response of 5.2% (one complete response [CR] and two partial responses [PRs]) was achieved. The overall survival was 12 months. The duration of the CR is more than 30 months. Both PRs lasted 6 months. No survival advantage was noted with either prior nephrectomy or biologic therapy. The majority of toxicities were Grade 2: anemia, anorexia, diarrhea, nausea/vomiting, and stomatitis. No toxic deaths occurred.

CONCLUSION

Low dose, continuous 5-FU demonstrated minimal activity in metastatic renal cancer.

A randomized, double-blind comparison of intravenous ondansetron alone and in combination with intravenous dexamethasone in the prevention of high-dose cisplatin-induced emesis

PURPOSE

This study compares the efficacy and safety of ondansetron alone with that of ondansetron plus dexamethasone in the prevention of emesis induced by high-dose cisplatin (> or = 100 mg/m2).

PATIENTS AND METHODS

This multicenter study used a randomized, double-blind, parallel-group design. Chemotherapy-naive patients were randomized to receive intravenous (IV) ondansetron (Zofran, Cerenex Pharmaceuticals, Research Triangle Park, NC) 0.15 mg/kg for three doses every 4 hours beginning 30 minutes before cisplatin administration either alone or in combination with dexamethasone 20 mg administered 45 minutes before cisplatin. Cisplatin (> or = 100 mg/m2) was administered as a single infusion (< or = 3 hours). Patients were monitored for emetic episodes (EEs), adverse events, and laboratory safety parameters for 24 hours after cisplatin administration.

RESULTS

A total of 275 patients were enrolled. Of these, 245 were assessable for efficacy. Patients who received ondansetron plus dexamethasone had a higher complete antiemetic response rate (61% v 46%, P = .02) and less nausea (posttreatment visual analog scale mean 18.2 v 32.8, P < .001) than did those who received ondansetron alone. The time to the first EE was longer for patients in the group that received ondansetron plus dexamethasone (P = .005). Headache (12%), diarrhea (2%), and abdominal colic (1%) were the most common antiemetic-related adverse events reported. The incidence of adverse events was similar between the treatment groups.

CONCLUSION

IV ondansetron in combination with dexamethasone is safe and more effective than ondansetron alone in the prevention of emesis induced by high-dose cisplatin.

Stratified, randomized, double-blind comparison of intravenous ondansetron administered as a multiple-dose regimen versus two single-dose regimens in the prevention of cisplatin-induced nausea and vomiting

PURPOSE

This study compares the efficacy and safety of two single-dose regimens with the approved three-dose regimen of ondansetron in the prevention of cisplatin-induced emesis.

PATIENTS AND METHODS

This multicenter study was a stratified, randomized, double-blind, and parallel group design. Chemotherapy-naive inpatients were randomized to receive intravenous (IV) ondansetron (Zofran; Glaxo Inc, Research Triangle Park, NC) 0.15 mg/kg times three doses, every 4 hours or a single 8-mg or 32-mg dose followed by two saline doses that began 30 minutes before cisplatin administration. Cisplatin (high-dose > or = 100 mg/m2 or medium-dose 50 to 70 mg/m2) was given as a single infusion (< or = 3 hours). Patients were monitored for emetic episodes, adverse events, and laboratory safety parameters for 24 hours after cisplatin administration.

RESULTS

A total of 699 patients (359 high-dose, 340 medium-dose) were enrolled. Of these, 618 were assessable for efficacy (15 ineligible, 66 protocol deviations). The 32-mg dose was superior to the 8-mg single dose with regard to total number of emetic episodes (high-dose, P = .015; medium-dose, P < .001), complete response (no emetic episodes: high-dose, 48% v 35%; P = .048; medium-dose, 73% v 50%; P = .001) and failure rate (> 5 emetic episodes, withdrawn or rescued: high-dose, 20% v 34%; P = .018; medium-dose, 9% v 23%; P = .005). The 32-mg single dose was also superior to the 0.15 mg/kg times three dose regimen with regard to total number of emetic episodes (medium-dose, P = .033) and failure rate (high-dose, 20% v 36%; P = .009; medium-dose, 9% v 22%; P = .011). Ondansetron was well tolerated. The most common adverse event was headache. An approximate 10-fold increase in the incidence of clinically significant transaminase elevations was observed in the high-dose versus medium-dose cisplatin strata (aspartate aminotransferase [AST], 6.5% v 0.7%; serum alanine aminotransferase [ALT], 5.0% v 0.3%).

CONCLUSION

A 32-mg single dose of ondansetron is more effective than a single 8-mg dose and is at least as effective as the standard regimen of 0.15 mg/kg times three doses in the prevention of cisplatin-induced acute emesis.

Randomized comparison of cisplatin plus fluorouracil and carboplatin plus fluorouracil versus methotrexate in advanced squamous-cell carcinoma of the head and neck: a Southwest Oncology Group study

PURPOSE

The Southwest Oncology Group (SWOG) conducted a randomized comparison of cisplatin plus fluorouracil (5-FU) and carboplatin plus 5-FU versus single-agent methotrexate (MTX) in patients with recurrent and metastatic squamous-cell carcinoma (SCC) of the head and neck. The primary objective was to compare separately the response rates of each combination regimen to standard weekly MTX.

PATIENTS AND METHODS

Two hundred seventy-seven patients diagnosed with SCC of the head and neck were randomized to one of three treatments: (1) cisplatin 100 mg/m2 intravenously (IV) on day 1 and 5-FU 1,000 mg/m2 per day for a 96-hour continuous infusion repeated every 21 days; (2) carboplatin 300 mg/m2 IV on day 1 and 5-FU 1,000 mg/m2 per day for a 96-hour continuous infusion repeated every 28 days; and (3) MTX 40 mg/m2 IV given weekly.

RESULTS

All three treatment regimens were well tolerated. However, both hematologic and nonhematologic toxicities were significantly greater with cisplatin plus 5-FU compared with MTX (P = .001). Toxicity from carboplatin plus 5-FU was intermediate compared with the other regimens. The complete and partial response rates were 32% for cisplatin plus 5-FU, 21% for carboplatin plus 5-FU, and 10% for MTX. The comparison of cisplatin plus 5-FU to MTX was statistically significant (P less than .001), and the comparison of carboplatin plus 5-FU to MTX was of borderline statistical significance (P = .05). Median response durations and median survival times were similar for all three treatment groups. Logistic regression models showed that only treatment assigned was associated significantly with response (P = .001). Cox proportional hazards models indicated that only performance status was associated significantly with survival (P less than .01).

CONCLUSIONS

We conclude that combination chemotherapy resulted in improved response rates but was associated with an increased toxicity and no improvement in overall survival. Therefore, new treatments that may alter the course of disease in recurrent head and neck cancer patients still need to be identified.

The incidence and significance of thromboembolic complications in patients with high-grade gliomas

Coagulation system abnormalities in patients with malignancy ranges from asymptomatic laboratory abnormalities to overt clinical manifestations. To determine the incidence and significance of clinically manifest thromboembolic phenomena in patients with high-grade gliomas, the records were analyzed of 77 patients that presented between January 1985 and June 1988. Fifteen patients (19%) had clinically manifest deep venous thrombosis and/or pulmonary emboli during the course of their disease. All these patients were ambulatory before and at the time of diagnosis of the event. The thromboembolic episodes occurred at the time of initial management of the primary tumor while there was documented clinical improvement in the functional status of the patient or at the time of progression of the disease. One patient died as a result of a pulmonary embolism; in two others, an embolism was a significant contributor to the patient's death. Anticoagulation resulted in complications in two of eight patients treated. Thromboembolic events occur with high frequency in patients with high-grade gliomas and contribute to the high morbidity and mortality seen in these patients. The optimum approach to screening and the treatment of these events has not been determined.

Phase II evaluation of amonafide in renal cell carcinoma. A Southwest Oncology Group study

Twenty four patients with advanced renal cell carcinoma were treated in a phase II trial with amonafide 300-450 mg/m2/day on days 1-5 every 21 days. There were no responders, 6 patients had stable disease, 14 experienced progressive disease and 4 were assumed to be non-responders as no evaluation was performed. There were no fatal toxicities although 8 patients had grade 3 or 4 granulocytopenia, 1 patient had grade 4 thrombocytopenia. Other toxicities included grade 3 diarrhea in 1 patient, grade 3 myopathy in 1 patient, severe nausea and vomiting in 1 patient and a facial rash, possibly a hypersensitivity reaction, in 1 patient. The median survival is 7.5 months. At this dosage and schedule, there is no evidence that amonafide has meaningful anti-tumor activity in patients with advanced renal cell carcinoma.

The Wayne State University experience with adjuvant chemotherapy of head and neck cancer

Because of the poor results of standard therapy in patients with locally advanced head and neck cancers, chemotherapy is increasingly used to improve the outcome of these patients. In resectable disease, chemotherapy is being investigated before definitive treatments, after surgery, concurrent with postoperative radiotherapy, after radiotherapy, and for possible laryngeal salvage. In unresectable cancers, chemotherapy before, concurrent with, and following radiotherapy is being investigated.

Evaluation of fludarabine phosphate in malignant melanoma. A Southwest Oncology Group study

Twenty-seven evaluable patients with advanced malignant melanoma received fludarabine phosphate in a daily x 5 injection. Initial dosing was based on the presence of previous radiation therapy. There was no response seen in these patients despite appropriate dose escalation. Myelosuppression occurred without significant sequelae.

The role of infection in the morbidity and mortality of patients with head and neck cancer undergoing multimodality therapy

Cancer of the head and neck is a common cancer worldwide. The majority of patients present with locally advanced disease. Recently a great deal of improvement has been made in multimodality therapy of this disease, warranting more careful consideration of factors affecting quality of life, disease course, and treatment. Infection is clearly a factor. Analysis of 662 hospital admissions of 169 head and neck cancer patients was performed. A definite infection was documented in 86 febrile episodes, pneumonia contributed to 40%, bacteremia to 13%, skin and soft tissue infection to 12%, and tracheobronchitis to 10%. Among the evaluated risk factors, foreign bodies, specifically intravenous (IV) cannulae and gastrostomy tubes, race, performance status, alcohol intake, and nutritional status were statistically significant variables that predicted for or were associated with infection. Infection contributed to 44% of the deaths.

Phase II evaluation of 4'deoxydoxorubicin in advanced renal cell carcinoma

4'Deoxydoxorubicin was evaluated in patients with advanced renal carcinoma. Only one partial remission was noted, and no significant cardiac toxicity was seen on serial evaluation of ejection fractions. Appropriate dose escalations were performed.

Metastatic squamous cell carcinoma of an unknown primary localized to the neck. Advantages of an aggressive treatment

Treatment of patients with squamous cell carcinoma (SCC) of an unknown primary localized to the neck is still controversial, particularly regarding advanced disease. We reviewed 41 such patients treated with surgery and/or radiotherapy (RT) (n = 25) or with combined modality treatment including chemotherapy (CH) (n = 16). The male to female ratio was 28 to 13, and the median age was 58 years (range, 32 to 94 years). There were 27 (66%) patients with poorly differentiated SCC and 8 with moderately differentiated or well-differentiated cancer. Twenty-three (56%) patients had N3 disease, 16 (39%) had N2, and 2 had N1. The majority of N3 patients have been treated with CH and RT (n = 12) or with RT alone (n = 9). The combined CH-RT was well tolerated, with no life-threatening toxicity. The complete response (CR) to CH-RT was 81% (11 patients have no evidence of disease [NED] currently). The median survival time of this group was 37+ months. Of the 25 patients who had surgery and/or RT as their first planned treatment, 7 (28%) have NED currently. The median survival time of this group was 24 months. Patients with N3 disease who received CH had a higher CR rate and a longer survival time as compared with those treated with surgery and/or RT, despite a higher (N3) stage of disease. These findings warrant further investigation in randomized cooperative studies.

Cellular DNA content parameters in untreated and recurrent squamous cell cancers of the head and neck

The presence and degree of DNA aneuploidy as measured by the DNA index (DI) and the S phase fraction (SPF) were determined by flow cytometry in 294 specimens from 237 patients with untreated and recurrent squamous cell carcinomas of the head and neck (SCCHN). A descriptive analysis was performed in which the specimen DNA parameters were correlated with stage, size of primary, degree of lymph node involvement, morphological grade, and treatment status of the corresponding patients. Approximately 70% of the previously untreated specimens contained DNA aneuploid populations (DI greater than 1.10) and three quarters had SPF that were above 15%. There was a strong, direct association between DI and SPF (P less than 0.001). There was no correlation of the presence or degree of DNA aneuploidy with the stage of the tumor or the size of the primary or conventional morphological grade of the tumor. Specimens from patients with recurrent tumors and untreated patients with N3 lymph nodes had significantly lower rates of DNA aneuploidy and mean DI. Serial determinations of DNA aneuploidy in patients with SCCHN undergoing cytotoxic therapy are ongoing and may prove useful in the identification and understanding of resistance and response in this tumor.

The correlation of specific variables of tumor differentiation with response rate and survival in patients with advanced head and neck cancer treated with induction chemotherapy

The authors have reported previously that conventionally defined grades of tumor morphology do not correlate with tumor response or survival in advanced squamous cell cancers of the head and neck (SCCHN) treated with cisplatinum combination induction therapy. This lack of correlation may be the result of the imprecision and subjectiveness of the conventional grade determination. To examine this possibility, response and survival were correlated with individual parameters of morphologic differentiation in 136 patients with advanced, untreated SCCHN. A multi-variable analysis of degree of keratinization, number of mitotic figures per high powered field, degree of nuclear differentiation, presence of vascular invasion, intensity of inflammatory response, and invasion pattern of the cancer was performed. The grade of each variable was weighted by assigning a score from 1 to 4, with 1 representing the most differentiated and 4 the least. The cumulative score of each specimen was tallied and assigned to one of three groups, less than 12, 12 to 18, and greater than 18, analogous to the conventional grades of well, moderately, and poorly differentiated, respectively. No correlation between the grade of individual morphologic variables and response to chemotherapy was demonstrated, or between tumor response and cumulative score groups. There was no correlation of the grade of individual morphologic variables or cumulative score groups with survival. Only the survival of patients achieving a complete response to chemotherapy was correlated with the cumulative score groups: 2-year survivals of 84%, 70%, and 46% for less than 12, 12 to 18, and greater than 18, respectively. Multi-parameter analysis of individual features of tumor differentiation is not superior to conventional morphologic analysis in predicting response to chemotherapy or survival in patients with advanced SCCHN.

The clinical syndrome of 5-fluorouracil cardiotoxicity

5-fluorouracil (FUra) is one of the most frequently used drugs in cancer treatment, particularly in combination with other agents. Its activity when administered as an infusion rather than a bolus has led to a renewed and increased use. A cardiotoxicity that mimics ischemia has been associated with the administration of FUra in cancer patients. This cardiotoxicity may manifest itself as: (a) dysrythmias with and without cardiorespiratory symptoms (b) ECG changes with and without cardiorespiratory symptoms (c) cardiorespiratory symptoms with and without ECG changes (d) acute myocardial infarct; symptoms and ECG changes (e) ventricular dysfunction (f) cardiogenic shock and (g) sudden death. Several case studies which illustrate the cardiotoxic sequelae that may be associated with the use of this drug are discussed. The incidence, contributing factors, risk factors and mechanisms underlying this phenomenon are undetermined. No appropriate recommendations for monitoring patients or for predicting those patients that will develop such toxicity while receiving FUra can be made at present. Prospective studies to determine the true incidence, spectrum and mechanisms causing this syndrome are ongoing and required for its understanding and prevention.

Evaluation of high-dose cisplatin and 5-FU infusion as initial therapy in advanced head and neck cancer

The combination of cisplatin and 5-fluorouracil (5-FU) infusion in head and neck cancer patients produces an overall response rate of 90% for advanced disease and 70% for recurrent disease. Whether or not escalating the platinum dose in combination with other agents, as has been done with refractory ovarian and testicular patients, would improve the response rates in patients with advanced head and neck cancer has not been evaluated. We undertook a study to determine the most efficacious dose of cisplatin that could be administered with 5-FU infusion in head and neck cancer patients. Eleven patients entered the study. Initial dose of cisplatin was 40 mg/m2 (in hypertonic saline) on days 1-5 plus 5-FU 1,000 mg/m2 on days 1-5 as a continuous infusion. Subsequent cisplatin doses were adjusted for the main toxicity, which was myelosuppression. The safest tolerable dose was 30 mg/m2 for 5 days. Overall response was 90% [45% complete response (CR) (5/11) plus 45% (5/11) partial response (PR)] which is comparable to that seen with cisplatin 100 mg/m2 and 5-FU in a 120-h infusion. Although patient numbers are small, there was no appreciable difference in response rate with higher dose cisplatin and there was a significant increase in serious toxicity.

Chemotherapy for paranasal sinus carcinoma. A 10-year experience at Wayne State University

The role of chemotherapy in the management of patients with cancer of the paranasal sinus has not been defined. An analysis of 24 evaluable patients treated with chemotherapy as part of their overall therapy was performed. There were 16 male patients and eight female patients. Sixteen patients were previously untreated and eight had recurrent disease after surgery and/or radiotherapy. Six of the previously untreated patients had metastatic disease on presentation (four central nervous system (CNS) and two lung), and four recurrent patients had CNS involvement. The majority of patients (78%) had squamous cell carcinoma. The chemotherapy regimens included cisplatin (CDDP), vincristine (VCR), and bleomycin (COB), 5-fluorouracil (5-FU) infusion and CDDP, or 5-FU/CDDP and methotrexate (MTX). All patients had computed tomography (CT) measurable disease. Previously untreated patients underwent surgery and/or radiotherapy postchemotherapy. The overall response rate to chemotherapy for previously untreated patients was 82% (complete response [CR] 44%, partial response [PR] 38%) and for recurrent patients 88% (CR 38%, PR 50%). Predominant toxicities were nausea, vomiting, myelosuppression, mucositis, and renal impairment. The median survival of the previously untreated patients, based on response to chemotherapy, was as follows: CR 21+ months (range, 10+ to 81 months), PR 13.5 months (range, 2 to 21 months), and no response (NR) 3 months (range, 1 to 7 months). The median survival of patients with recurrent disease was as follows: CR 16 months, PR 13.5 months, and NR 5 months. We conclude that patients with paranasal cancers are responsive to CDDP-containing combinations. The role of adjuvant chemotherapy in previously untreated, locally advanced patients needs to be demonstrated by future randomized trials.

Proto-chemotherapy in advanced head and neck cancer

Induction (proto) chemotherapy consisting of 3 courses of cisplatin and 120-hour 5-fluorouracil infusion was administered to 88 patients who had locally advanced, previously untreated head and neck cancer. The majority (81%) of these patients were classified as stage IV, and 17% had second primary carcinomas of the upper aerodigestive tract. An overall response rate of 94% was observed, with a 54% incidence of complete clinical response. The toxicity of the chemotherapy was judged acceptable, and no life-threatening or fatal drug-related side effects occurred. Twenty-four percent of the patients failed to comply with recommended standard treatment. In patients achieving a complete clinical response, 47% refused recommended surgery. Any response less than a complete clinical response to induction chemotherapy was not associated with any survival advantage. We conclude that future research efforts should be directed toward the identification of chemotherapeutic regimins that maximize the incidence of complete clinical response. In addition, any large-scale chemotherapy trial in patients with resectable disease should avoid the use of an induction sequence to minimize compliance problems with standard treatment.

A randomized trial of cisplatin (CACP) + 5-fluorouracil (5-FU) infusion and CACP + 5-FU bolus for recurrent and advanced squamous cell carcinoma of the head and neck

One of the most active chemotherapeutic regimens for treatment of advanced and recurrent head and neck cancer is cisplatin (CACP) + 5-fluorouracil (5-FU) infusion with a response rate of 90% in advanced, previously untreated patients and 70% in patients with recurrent disease. Forty-four patients from two Wayne State University-affiliated hospitals were entered into a randomized trial of CACP (100 mg/m2) day 1 and 24-hour infusion of 5-FU (1000 mg/m2) days 1 through 4 versus CACP (100 mg/m2) day 1 and bolus 5-FU (600 mg/m2) day 1 and day 8. Thirty-eight patients were evaluable for three induction courses. Response for the infusion arm was 72% (4/18 complete response [CR] + 9/18 partial response [PR]). Response for the bolus arm was 20% (2/20 CR + 2/20 PR). The difference in response was statistically significant by chi-square analysis (P less than 0.01). Seventy percent of the patients on the bolus arm experienced leukopenia with several episodes of grades 3 and 4 leukopenia. In addition, 50% of the patients on the bolus arm experienced thrombocytopenia. Stomatitis was more frequent on the infusion arm but it was mild and reversible. The complete responders on either arm have a median survival of 120+ weeks; partial responders, 30 weeks. Cisplatin + 5-FU infusion produces a superior response as initial chemotherapy for three courses compared with CACP and 5-FU bolus.

Superior clinical response and survival rates with initial bolus of cisplatin and 120 hour infusion of 5-fluorouracil before definitive therapy for locally advanced head and neck cancer

One hundred ninety-one patients were treated by one of three cisplatin-containing multidrug protocols. The initial 77 patients received two courses of cisplatin and vincristine plus bleomycin. The next 26 patients received two courses of 5-fluorouracil and cisplatin, and the final 88 patients were placed on a three course 5-fluorouracil and cisplatin protocol. Overall response rates were similar for each of the three protocols. The complete response rate, however, was much better (54 percent) for three course 5-fluorouracil and cisplatin versus cisplatin vincristine, and bleomycin (29 percent) and two course 5-fluorouracil and cisplatin (19 percent). Survival curves were also better for the three course 5-fluorouracil and cisplatin segment of this nonrandomized pilot study.

Aclacinomycin. Phase II evaluation in advanced squamous carcinoma of the head and neck

Aclacinomycin-A was evaluated in a phase II trial for advanced head and neck cancer. A weekly infusion of 65 mg/m2 was used. Eighteen patients were entered. Fifteen patients were evaluable for response and toxicity. One was evaluable for toxicity only and two died before completion of a full course of therapy. One patient without previous chemotherapy achieved a PR in a neck node for a short time. Six patients had stable disease with a median to progression of 6 weeks. Major toxicity encountered was bone marrow suppression. Aclacinomycin-A appears to have no activity in squamous cancer of the head and neck.

Correlation between response to cisplatinum-combination chemotherapy and subsequent radiotherapy in previously untreated patients with advanced squamous cell cancers of the head and neck

Induction chemotherapy, followed by surgery and/or radiotherapy was utilized in patients with advanced squamous cell carcinoma of the head and neck. During these trials, the authors observed that response to chemotherapy predicts further response to subsequent radiotherapy. This study was comprised of 57 patients with 60 separate neoplasms who demonstrated less than complete response (partial or no response) to initial treatment with a combination chemotherapy containing cisplatin. Subsequently radiotherapy, either 5000 rad preoperatively or 6600 rad as definitive therapy, was employed. Forty-one of the 42 tumors with initial partial response to chemotherapy also responded to radiotherapy (97.6%). Only one of the 18 tumors that initially failed to respond to chemotherapy subsequently responded to radiotherapy (5.5%). This observation suggests that patients with head and neck cancer sensitive to initial chemotherapy share parameters that are also radiation sensitive.

Cisplatin and 5-fluorouracil infusion in patients with recurrent and disseminated epidermoid cancer of the head and neck

The combination of cisplatin and 96-hour infusion of 5-fluorouracil (5-FU) was evaluated in 30 patients with recurrent (local and regional) and disseminated histologically proven epidermoid cancer of the head and neck who failed surgery and radiotherapy. Cisplatin 100 mg/M2 intravenous (IV) bolus was given on day 1 with hydration and mannitol diuresis; 5-FU 1000 mg/M2 per day for 96-hour infusion was started immediately after cisplatin on day 1. All patients had measurable lesions. Eight (27%) patients achieved complete response (CR), and 13 (43%) had partial response (PR). Overall response rate was 70% (8 of 30 CR and 13 of 30 PR). Response rate in patients with recurrent local and regional disease was 89% (17/19) with median survival of 32 weeks, while response in patients with disseminated disease was 36% (4/11) with median survival of 24 weeks. Patients with good performance status (PS) (greater than or equal to 70%) had a response rate of 79% (19/24), while those with poor PS (less than 70%) had a response rate of 33% (2/6). Seven patients with recurrent disease who had a response to this chemotherapy went to further salvage surgical procedures. It is concluded that the combination of cisplatin and 5-FU is very effective and well tolerated in these patients, and leads to further salvage in some patients with improved longevity and quality of life.
