Creatinine clearance as a predictor of ultrafilterable platinum disposition in cancer patients treated with cisplatin: relationship between peak ultrafilterable platinum plasma levels and nephrotoxicity.
Authors: Reece P A , Stafford I , Russell J , Khan M , Gill P G
Published: February 2017

Ultrafilterable platinum (UP) disposition was studied in 22 cancer patients receiving their first course of cisplatin (50 to 140 mg/m2) by two-hour infusion. UP plasma and urinary platinum levels were quantitated using a high-performance liquid chromatographic (HPLC) assay, which was selective for cisplatin and active platinum metabolites. Creatinine clearance was determined in all patients at the time of the pharmacokinetic studies and ranged from 58 to 214 mL/min. Creatinine clearance was a poor predictor of UP disposition in patients, probably as a consequence of the complex renal clearance mechanism for UP in the human kidney, which involves both tubular secretion and reabsorption. However, the peak plasma level of UP was closely related to the area under curve (AUC) of UP (r2 = .831), P less than .0001) and was significantly correlated with the decline in creatinine clearance observed after four courses of cisplatin therapy to 12 of the patients (r2 = .727, P less than .005). Cisplatin dose and the AUC of UP were less satisfactory predictors of the change in creatinine clearance with four courses of therapy (r2 = .488, P less than .025 and r2 = .623, P less than .005). The large interpatient variability in all the parameters of cisplatin disposition measured in this study suggested that there may be a role for individualization of cisplatin dosage based on a peak level obtained in the first course of therapy. Longer term infusion of cisplatin could also be justified.
A clinical and pharmacokinetic study of mitoxantrone in acute nonlymphocytic leukemia.

Published: February 2017

Twenty-two patients with relapsed or refractory acute leukemia received 31 treatment courses of mitoxantrone (10 to 12 mg/m2/d) as a one-hour infusion for five days. Seven of the 13 patients who had greater than or equal to 95% reduction in the leukemia cell mass, calculated using the bone marrow examination on day 6, achieved a complete remission (CR). These remissions lasted up to 14 months without additional therapy. There were no CRs among the 18 patients who had less than 95% cytoreduction by day 6. The sequential addition of 5-azacytidine (200 mg/m2/d) for three days in those patients with residual disease on day 6 provided little additional benefit. Nonhematological toxicity from mitoxantrone was mild, although fever and infection were common. A new high-performance liquid chromatography (HPLC) assay was used to describe the clinical pharmacokinetics of mitoxantrone. Neither clinical response nor toxicity was strongly correlated with the peak plasma mitoxantrone concentration on the first day (mean +/- SD, 510 +/- 206 ng/mL), nor the area under the concentration-time curve (484 +/- 229 ng X h/mL), nor the systemic clearance (405 +/- 124 mL/min/m2). Mitoxantrone causes rapid cytoreduction in acute nonlymphocytic leukemia (ANLL), but the optimal dose and schedule remain to be determined.

Published: February 2017

A prospective clinical trial was developed to evaluate efficacy, toxicity, and patient compliance to adjuvant chemotherapy following surgery and postoperative radiation therapy in patients with squamous-cell carcinoma of the head and neck with extracapsular spread of tumor in cervical metastases. Following postoperative radiation therapy, 18 courses of methotrexate (MTX) and 5-fluorouracil (5-FU) were administered over 6 months. Fifty patients were registered. A total of 771 doses were administered. Dose reduction was required 72 times. Therapy was stopped in one patient (2%) because of toxicity. Three patients (6%) refused to complete the adjuvant therapy. Adjusted 2-year no evidence of disease (NED) survival is 66%. This study demonstrates that patients with advanced squamous-cell carcinoma of the head and neck can undertake an aggressive program of adjuvant MTX/5-FU with acceptable compliance and toxicities. Preliminary data generated in this nonrandomized study support the call for a prospective randomized multiinstitutional trial of this program.
Wound complications in the multimodality treatment of extremity and superficial truncal sarcomas.

Published: February 2017

The incidence and severity of wound complications were examined in 105 patients with extremity and superficial truncal sarcomas who were eligible for wide local excision with or without adjuvant perioperative brachytherapy (BRT) and/or chemotherapy. Fifty-four cases from the eligible group were entered into a randomized prospective trial of the efficacy of BRT in decreasing local recurrence. In the eligible patients, major wound complications occurred in nine of 41 (22%) of the BRT cases, compared with two of 64 (3%) of the non-BRT patients, which was a significant increase (P = .002). The combined frequency of major and moderate wound complications was also significantly increased in the BRT (18 of 41, 44%) compared with the non-BRT (nine of 64, 14%) patients (P = .0006). The median duration to complete resolution of these complications was 189 days (14 to 597) in the BRT, compared with 49 (11 to 170) days in the non-BRT group (P = .0005); however, no amputations were required, and only 14% of the BRT-associated wound complications were of prolonged duration, ie, greater than 200 days. In the randomized study, both the total number of complications, and the combination of major and moderate complications were increased significantly in the BRT v the non-BRT patients. Adjuvant Adriamycin (Adria Laboratories, Columbus, OH) administered in 60 mg/m2 increments to a cumulative dose of 540 mg/m2 did not appear to impair wound healing even when administered within 15 days of operation. Significant wound complications occur in major resections of extremity and superficial truncal sarcomas. If the addition of adjuvant BRT produces a decrease in local recurrence, then either patient selection will have to be more rigidly applied, especially in wounds where skin flap blood supply is tenuous, or the technique will need to be modified to balance the short-term aim of reducing wound complications with the long-term goal of local tumor control.
High-dose cytosine arabinoside in the treatment of acute myelogenous leukemia: contributions to outcome of clinical and laboratory attributes.
Authors: Curtis J E , Messner H A , Minden M D , Minkin S , McCulloch E A
Published: February 2017

High-dose cytosine arabinoside (HDAra-C) has been used for remission induction, and in conventional doses for maintenance in a trial of single-agent therapy in 43 previously untreated patients with acute myelogenous leukemia (AML). Rationale for the trial was provided by the observed decrease in leukemic blast cell self-renewal in culture following exposure to Ara-C. Compared with a previous trial of 57 patients treated with multidrug therapy, single-drug Ara-C was associated with a significantly improved complete remission rate (P = .010), although the survival time was not increased. All patients with low self-renewal responded to HDAra-C in contrast to the previous trial where some patients with this phenotype failed remission induction. The clinical observations are consistent with the view that the antileukemic effect of Ara-C has some specificity for cellular events required for self-renewal of blast cells. Exposure in vivo to Ara-C was associated with an increase in blast stem cell renewal at relapse, indicating that maintenance with other drugs should be tested. The study demonstrates the importance of biological attributes in design and analysis of clinical trials.
Cisplatin therapy for disseminated mixed mesodermal sarcoma of the uterus.

Published: February 2017

Eighteen patients with metastatic mixed mesodermal sarcoma of the uterus received cisplatin therapy at the University of Texas (UT) M.D. Anderson Hospital and Tumor Institute at Houston. The dose of cisplatin varied from 75 mg/m2 to 100 mg/m2. Previous therapy included surgery in 11 patients, radiotherapy in two patients, and surgery plus radiotherapy in four patients. One patient had no prior therapy. Seven patients had also received prior chemotherapy with doxorubicin. Of 12 patients with measurable disease, one (8%) had a complete response and four (33%) had a partial response for an overall response rate of 42%. The median progression-free survival of patients treated with cisplatin as first- and second-line therapy was 4.5 and 5.5 months, respectively. Cisplatin demonstrated moderate activity with mild toxicity in this group of patients with metastatic mixed mesodermal uterine sarcomas. Further studies including cisplatin-containing combination regimens seem to be warranted.

Published: February 2017

Conservative treatment of esophageal cancer with radiation therapy has afforded few long-term survivors. In order to improve outcome, patients with locoregional disease were treated using a combined modality approach. Patients were treated with chemotherapy consisting of a 96-hour continuous infusion of 5-fluorouracil (5-FU), 1,000 mg/m2/d, days 1 to 4 and days 29 to 32; cisplatin 75 mg/m2, day 1 and 29; and radiation 3,000 rad, days 1 to 19. In the absence of progressive disease, patients underwent esophagectomy. One hundred twenty-eight patients were registered of whom 113 were eligible and 106 were evaluable. Toxicity included gastrointestinal (GI) symptoms, mucositis, and myelosuppression. One hundred two patients completed chemoradiotherapy. Following its completion, 11 patients refused surgery, six were considered poor surgical risks, and 14 had progressive disease. Of the remaining 71 patients, 16 had unresectable disease, 13 had residual disease which was incompletely resected, 24 had disease which could be completely resected, and 18 were without disease on pathologic examination. The overall operability rate was 63% and the overall resectability rate, 49%. Surgical mortality was 11%. Eighty-nine of 113 eligible patients have died, with a median survival of 12 months and a 2-year survival of 28%. The median postsurgical survival for all 71 patients was 14 months and was 32 months for those patients attaining complete remission (CR). Combined modality therapy remains an investigational approach. Attempts should be directed at increasing response rate to initial therapy. A randomized comparison between combined modality treatment and radiation therapy is necessary to definitively determine the usefulness of this more aggressive approach.

Published: February 2017

Twenty-three patients (16 male, seven female) with hepatocellular carcinoma (HCC) were treated by hepatic arterial infusion (HAI) of mitoxantrone every 4 weeks. At each treatment, a catheter was inserted percutaneously into the main hepatic artery via the femoral artery under image intensification. Treatment consisted of a 24-hour continuous HAI of mitoxantrone, 6 mg/m2/d X 3 (eight patients) or 10 mg/m2/d X 3 (14 patients) without heparin. Eight patients had only one infusion, nine patients four infusions, five patients three infusions, two patients two infusions, and one patient five infusions. A partial response was seen in six patients, with a median duration of 20 weeks (range, 18 to 38 weeks). Five patients achieved stable disease, with a median duration of 20 weeks (range, 11 to 42 weeks). The median survival of the overall group was 22 weeks. Survivals of responding, stable, and nonresponding patients were 32 weeks, 24 weeks, and 9 weeks, respectively. Complications of catheter placement included asymptomatic dissection of the hepatic artery (one patient), and asymptomatic thrombosis of the hepatic artery (five patients). Three patients experienced mild nausea and vomiting, and six patients had mild to moderate alopecia. Granulocytopenia was frequent at both dose schedules. The granulocyte nadir was greater than 1,000/microL in 34% of evaluable courses, 500 to 1,000/microL in 32%, and less than 500/microL in 34% of courses. Two patients developed neutropenia-associated fever. A platelet nadir below 100,000/microL was seen after only 10% of courses, and only two patients had platelets below 50,000/microL. Seven patients received doxorubicin after progression on mitoxantrone. Four received systemic doxorubicin, 50 mg/m2, and three HAI of doxorubicin, 25 mg/m2, for three days. Two patients achieved partial response (18 weeks and 32 weeks) to HAI doxorubicin. Mitoxantrone has activity in HCC and is well tolerated when administered by HAI. It is not entirely cross-resistant with doxorubicin.

Published: February 2017

Eight patients with refractory ovarian cancer were treated on a pilot protocol of verapamil plus Adriamycin (Adria Laboratories, Columbus, OH). This trial was based on our previous laboratory studies which demonstrated that Adriamycin resistance in human ovarian cancer cell lines could be partially reversed by exposure of the cells to high concentrations of verapamil (3,000 ng/mL). Patients were treated in an intensive care unit with continuous cardiovascular monitoring. The dose of verapamil was escalated in each patient until hypotension or heart block developed, and this dose was maintained for 72 hours. Adriamycin (50 mg/m2) was infused over 24 hours during the second day of the verapamil infusion and verapamil alone was administered on the third day in an effort to block efflux from drug-resistant cells. This intensive approach led to a median plasma verapamil level of 1,273 ng/mL (range, 720 to 2,767). However, the high infusion rates of verapamil (9 micrograms/kg/min) required to achieve these plasma levels produced an unacceptable degree of cardiac toxicity. Two patients developed transient atropine-responsive complete heart block and four patients developed transient congestive heart failure with increases in pulmonary capillary wedge pressure. There was no evidence that the noncardiac toxicities of Adriamycin were enhanced by verapamil. There were no objective responses to therapy. Future studies should use less cardiotoxic calcium channel blockers that can be safely administered to produce the plasma levels required for in vitro sensitization of drug resistant cells.
Subcutaneous infusion of bleomycin--a practical alternative to intravenous infusion.

Published: February 2017

The phase specificity and short half-life of bleomycin make it likely that it would be more effective when administered by continuous infusion. This is supported by studies using cell lines, as well as by animal studies and clinical experience in humans. This study was conducted to compare the pharmacokinetics of intravenous (IV) and subcutaneous infusions of bleomycin. The serum concentrations of bleomycin were measured using a sensitive and specific radioimmunoassay. The results demonstrate similar plasma concentrations and area under the curve for both routes. The subcutaneous infusions were well tolerated, without local discomfort or excoriation. Subcutaneous infusion of bleomycin may thus offer a practical alternative to IV infusions and can be administered to patients who are ambulatory and out of hospital.
Gonadal function after surgery and chemotherapy in men with stage II and III nonseminomatous testicular tumors.
Authors: Nijman J M , Schraffordt Koops H , Kremer J , Sleijfer D T
Published: February 2017

The gonadal functions were studied in 54 patients with disseminated nonseminomatous testicular tumors who had been subjected to combination chemotherapy (cisplatin, vinblastine, and bleomycin [PVB]) and surgery (hemiorchiectomy, retroperitoneal lymph node dissection or removal of retroperitoneal residual tumor after chemotherapy) and in 17 patients with a stage I tumor subjected to hemiorchiectomy exclusively. In the patients treated with chemotherapy, the plasma testosterone levels remained at the lower limit of normal and the luteinizing hormone (LH) levels remained elevated for 2 years after completion of treatment. The follicle-stimulating hormone (FSH) levels also remained significantly elevated, but showed a tendency to decrease after 2 years. Semen analysis was performed in 25 patients; of the other patients, 18 had no antegrade ejaculation, eight had undergone a vasectomy and three patients did not cooperate. Before treatment, 72% of the patients showed azoo- or oligozoospermia; 2 years after discontinuation of the chemotherapy, 48% had azoo- or oligozoospermia while 28% had more than 60 X 10(6) spermatozoa/mL. However, interestingly the proportion of patients with azoospermia had increased from 4% to 28%. In the course of this study, eight pregnancies occurred; one ended in an early spontaneous abortion; the other seven pregnancies ran an uncomplicated course. Seven healthy children were born. In 17 patients with a stage I tumor treated by hemiorchiectomy only, the testosterone, LH and FSH levels were also observed for 2 years; until 2 years after treatment, the testosterone levels remained lower and the FSH levels remained higher than normal. Insufficiency of the Leydig's cells in the unaffected gonad appeared to be responsible for the altered hormone concentrations in the blood.

Published: February 2017

We assessed the efficacy of local fibrinolytic therapy in 35 axillary-subclavian vein thromboses (SVT) that occurred in cancer patients with percutaneous central venous catheters (CVC). These catheters were indwelling for a median of 1 month (range, one day to 10 months) before thrombosis developed. Urokinase was administered at a dose of 500 to 2,000 U/kg/h. Complete lysis occurred in 25 of 30 thrombi that were directly infused, after a median of four days. Complete lysis occurred in one of 12 thrombi that could not be directly infused with urokinase and in two of six with associated phlebitis. Eighty-one percent of the thrombi that were symptomatic for less than 1 week before treatment resolved, compared with 56% present for longer than 1 week. Sixteen patients who had complete (12) or partial (four) thrombolysis did not have their CVCs removed. All four patients with partial thrombolysis had recurrent thrombosis at a median of eight days (range, one to 90). Only two patients who had complete thrombolysis had recurrent thrombosis, at 8 and 16 months. Only minor hemorrhagic toxicity was seen.

Published: February 2017

This study was designed to evaluate the efficacy of surgical resection of the primary tumor and lymph nodes in patients with localized small-cell carcinoma who had responded to induction chemotherapy. The study was performed in 37 patients who received two cycles of chemotherapy consisting of cyclophosphamide, doxorubicin, and etoposide. Those patients who achieved a complete or partial (greater than 50%) response were evaluated for thoracotomy and the primary tumor and regional lymph nodes excised when feasible. Postoperatively, the patients received prophylactic cranial irradiation and were maintained on the same chemotherapy for an average of 11 months. Twelve patients were resected and found to have residual small-cell carcinoma in the operative specimen (ten) or no residual disease (two). Seven of these patients (58%) are alive without evidence of disease (median follow-up, 24 months). Seven other patients who were resected proved to have either residual foci or small-cell carcinoma mixed with adenocarcinoma or large-cell carcinoma (four) or only focal areas of adenocarcinoma, large-cell carcinoma, or squamous-cell carcinoma with no evidence of residual small-cell carcinoma. Five of these patients (71%) are alive without evidence of disease (median follow-up, 36 months). Two of the 16 patients who were not resected but treated with chemotherapy and radiation are alive at 15 and 31 months without evidence of disease, the other 14 are dead of disease.

Seven patients with acute nonlymphocytic leukemia (ANL) following therapy for Hodgkin's disease (HD) were treated with cyclophosphamide (Cy) alone or combined with 10.00 to 15.75 Gy total body irradiation (TBI) and marrow transplantation. Five patients were transplanted without an attempt at prior remission induction, one patient following failure of remission induction and one patient in first remission following successful induction. Four patients died of multiorgan failure, 15 to 70 days after transplant. Three patients died of progressive or recurrent leukemia 56, 120, and 280 days after transplant. These results illustrate the difficulty of treating patients for secondary leukemia with marrow transplantation and suggest that transplantation in the preleukemic phase should be studied.

Thirty-one Chinese patients with peripheral T cell lymphoma (PTCL) were reviewed. Using the modified Japanese Lymphoma Group classification, there were nine (29%) of the pleomorphic type, 16 (52%) immunoblastic lymphadenopathy (IBL)-like, two (7%) T-zone lymphoma, and one (3%) Lennert's lymphoepithelioid type. Three (9%) were not classifiable. All were positive for T11 (E rosette receptor antigen). Fifty-four percent (15 of 28) were positive predominantly for T4 (helper T cell) and 46% (13/28) for T8 (suppressor T cell). The median age of the patients was 57 years. They usually presented with advanced disease, and while extranodal involvement was common, CNS disease was not seen. The IBL-like type was associated with a positive Coombs' test and polyclonal hypergammaglobulinemia. Five of the nine pleomorphic type were checked for antibody to HTLV-I virus and all were negative. PTCL was associated with poor prognosis, which was not influenced by the histologic subtypes and the T4/T8 phenotypes. The complete response rate of 13 consecutive patients who received the BACOP (bleomycin, doxorubicin, cyclophosphamide, vincristine, and prednisone) L17M regimen was significantly better than the 16 historic controls who received other less-intensive regiments, 84% v 19% (P less than .01). The relapse rate was also significantly lower, 9% v 100% (P less than .001). There appeared to be an improvement in the disease-free survival (DFS) (80% v 0% at 18 months), as well as the overall survival (60% v 36% at 18 months), but the differences did not reach statistical significance due to small sample sizes.
Dose intensity analysis of chemotherapy regimens in ovarian carcinoma.
Authors: Levin L , Hryniuk W M
Published: February 2017

The relationship between outcome and dose intensity was analyzed for first-line chemotherapy of advanced ovarian cancer using a particular CHAP (cyclophosphamide, hexamethylmelamine, Adriamycin [Adria Laboratories, Columbus, OH], cisplatin) regimen as the standard. Previously described techniques were used to calculate the average dose intensity of regimens containing one, two, three, or all four drugs of CHAP, relative to the standard. The average relative dose intensity, especially the relative dose intensity of cisplatin, correlated significantly with clinical response and with median survival time (MST) of the entire group (not just the remitters). There was a distinct advantage for multiagent regimens over single alkylating agents and especially for multiagent regimens containing cisplatin. Survival correlated with response rate (of multiagent regimens). This analysis suggests that dose intensity is a determinant of treatment outcome. Prospective randomized trials would be required to test whether, and to what extent, dose intensity determines outcome independently of total amount of drug given, performance status, or other factors. If dose intensity does determine outcome, methods of increasing it should be tested in an attempt to improve treatment results.

Published: February 2017

This study addressed two major questions regarding therapeutic use of Adriamycin ([Adr] Adria Laboratories, Columbus, OH) in adult soft tissue sarcomas: the influence of dosing schedule and the value of adding imidazole carboxamide (DTIC) to Adr. Patients with objectively measurable metastatic soft tissue sarcomas were randomized to Adr 70 mg/m2 intravenously (IV) day 1 and every 3 weeks (94 patients); Adr 20 mg/m2 IV day 1, 2, and 3, and 15 mg/m2 IV day 8 and weekly thereafter (89 patients); and Adr 60 mg/m2 IV day 1 and DTIC 250 mg/m2 days 1 to 5, repeated every 3 weeks (92 patients). The regimens using Adr as a single agent resulted in an equivalent response frequency (18% and 16%) and survival (median, 8.0 and 8.4 months). DTIC significantly increased (P less than .02) the overall response frequency of Adr to 30%. However, DTIC did not influence survival (median, 8.0 months) or increase the number of complete responses. The toxicities of the two single-agent regimens differed: Adr weekly resulted in more stomatitis (P = .09) and less hematologic toxicity (P less than .05). DTIC resulted in substantially increased toxicity, primarily gastrointestinal (P less than .002); overall, 98% of patients receiving Adr-DTIC experienced moderate or worse toxicity. To decrease the potential for error in interpretation of treatment results, histopathological confirmation of diagnosis was undertaken by a panel of reference pathologists; pathology slides were submitted on 97% of entered patients. The on-study clinical diagnosis was affirmed in 199 of 316 patients (63%) with a final review. In 23% of patients, the panel agreed with the diagnosis of soft tissue sarcoma, but not with the type. In 14%, the panel concluded that a diagnosis of mesenchymal malignancy could not be affirmed. Final treatment results were based on the 275 pathologically confirmed, eligible patients. The most common histological subtype entered was leiomyosarcoma (99 patients). The response to Adr-DTIC of this subtype was higher (44%) than that of any other subtype. However, this difference alone was not responsible for the overall superiority of the combination. This confirmed that the combination of DTIC plus Adr adds to the response rate of Adr alone in soft tissue sarcomas. Whether the increased response frequency, without an impact on survival, is worth the significantly greater toxicity remains a subjective judgement that must be made within the context of the individual patient.
Zoladex: a sustained-release, monthly luteinizing hormone-releasing hormone analogue for the treatment of advanced prostate cancer.

Published: February 2017

Zoladex, a sustained-release luteinizing hormone--releasing hormone (LHRH) analogue administered by subcutaneous injection every 28 days, was evaluated at three dose levels in 46 men with untreated advanced prostate cancer. All three Zoladex doses yielded similar endocrinologic effects. After initial transient increases in serum luteinizing hormone, follicle-stimulating hormone, and testosterone concentrations, serum testosterone was suppressed uniformly to castration levels within 22 days. At a median follow-up of 41 weeks, Zoladex had maintained persistent suppression of serum testosterone. Measurements of serum Zoladex levels indicated that release of the drug from the injected depot was sustained over a period of 1 month and that there was no drug accumulation as evaluated over an initial 3-month period. No antibodies to Zoladex were detected. Tumor regression rates and side effects with Zoladex therapy were similar to those reported with daily injections of subcutaneous LHRH therapy. Signs and symptoms consistent with a brief tumor flare after the first injection of the LHRH analogue were noted in eight (17%) of the study entrants. Spinal cord compression was observed in two patients within 1 week from the onset of therapy. Zoladex is considered to be an effective, sustained-release LHRH analogue for the treatment of patients with prostate cancer.

Published: February 2017

CNS dysfunction, especially impaired cerebellar function, is the dose-limiting toxicity associated with high-dose cytosine arabinoside, which precludes doses of greater than 48 g/m2. Four hundred eighteen patients between the ages of 2 and 74 years with leukemia or lymphoma received 36 to 48 g/m2 cytosine arabinoside either alone or with anthracycline antibiotics, 4'-(9-acridinylamino) methane sulfon-m-anisidine (m-AMSA), or total body irradiation. In only 35 of 418 patients (8%) did severe cerebellar toxicity develop; it was irreversible or fatal in four (1%) patients. The age of the patient was a critical factor in the incidence of severe cerebellar toxicity. Patients greater than 50 years old had a statistically significant greater incidence of cerebellar toxicity compared with younger patients (26/137, 19%, v 9/281, 3%; P less than .0005, chi 2). Neither the diagnosis, disease status, sex, nor the regimen altered the incidence of severe cerebellar toxicity (when corrected for age). A second course of high-dose cytosine arabinoside, administered to 62 patients, did not increase the incidence of severe cerebellar toxicity, which occurred in five (8%) of these patients. Two of the five patients had severe toxicity with the initial course. Of the 60 patients with no antecedent cerebellar dysfunction, three (5%) had severe toxicity with the second course: one of 41 patients were less than 50 years old; two of 19 patients were greater than or equal to 50 years. Since the occurrence of severe cerebellar dysfunction is greatly affected by age, reduced doses of high-dose cytosine arabinoside should be given to patients greater than 50 years old, and methods for reducing the cerebellar toxicity should be investigated in these patients.
Cisplatin, doxorubicin, and 5-fluorouracil chemotherapy for salivary gland malignancies: a pilot study of the Northern California Oncology Group.

Published: February 2017

Seventeen patients with advanced or recurrent salivary gland cancer were treated with cisplatin, doxorubicin, and 5-fluorouracil combination chemotherapy (PAF). Two patients achieved a complete response and four patients achieved a partial response, for an overall response rate of 35%. Six of the nine patients who received PAF in the neoadjuvant setting did not respond and proceeded to surgery and/or radiation therapy. No difference in response rate was found between those patients treated for recurrent disease v those treated with neoadjuvant chemotherapy. All three patients with adenocarcinoma responded. The response duration in patients with metastatic or recurrent disease ranged from 6 to 15 months. The PAF regimen was delivered primarily in the outpatient setting and was associated with acceptable toxicity. PAF demonstrates activity in salivary gland malignancies, and further evaluation of this combination seems warranted.
Stage I to IIB Hodgkin's disease: the combined experience at Stanford University and the Joint Center for Radiation Therapy.

Published: February 2017

The treatment records of 180 patients with pathological stage (PS) IB to IIB Hodgkin's disease treated at Stanford University Medical Center (SUMC) or the Joint Center for Radiation Therapy (JCRT) were reviewed. Pretreatment characteristics were analyzed to assess their influence on survival and freedom from relapse (FFR). The two most important disease characteristics predictive of relapse were the number and type of B symptoms present and the mediastinal mass ratio (MMR). Patients with both fevers and weight loss had a 7-year survival and FFR of only 57% and 48%, respectively. The poor prognosis in this group was apparent for treatment with either radiation (XRT) alone or combined modality therapy (CMT). Patients with night sweats only had no adverse effect of B symptoms on outcome. Patients with a MMR greater than 1/3 had a 7-year FFR of only 58% after XRT, but 79% after CMT (P = .12). The 7-year survivals for these patients were 85% and 88%, respectively. CMT improved the FFR of the entire group of 180 patients when compared with XRT (7-year FFR 86% and 74%, respectively, P = .02); however, survival in the two treatment groups was similar (88% and 89%). Among patients treated with radiation alone, there was a similar survival and FFR irrespective of whether pelvic irradiation was included in the initial treatment fields.
Elevation of cerebrospinal fluid catecholamine metabolites in patients with intracranial tumors of neuroectodermal origin.
Authors: Bostrom B , Mirkin B L
Published: February 2017

The concentrations of homovanillic acid (HVA), hydroxymethoxyphenylethyleneglycol (HMPG), and vanillylmandelic acid (VMA) were determined in lumbar cerebrospinal fluid (CSF) specimens. The study population consisted of the following groups: control subjects with malignancies of nonneuroectodermal origin (mostly leukemia in remission), neuroblastoma (extracranial and intracranial or cranial metastases), brain tumors (neuroectodermal and glial), and retinoblastoma. A significant increase in the CSF concentration of HVA was observed in patients with brain tumors (neuroectodermal), neuroblastoma (intracranial or cranial metastases), and retinoblastoma when compared with age-matched controls. In contrast, HMPG and VMA concentrations did not differ from controls except in patients with neuroblastoma (intracranial or cranial metastases) and brain tumors (neuroectodermal) who had significant elevations in HMPG and VMA, respectively. An inverse correlation was noted between the CSF concentration of HVA and clinical response to therapy. Nonresponding patients exhibited increases in HVA when compared with pretreatment values. These data suggest that the quantitative determination of catecholamine metabolites in lumbar CSF is an effective method for diagnosing intracranial tumors of neuroectodermal origin and assessing their response to therapy.

Thirty-six patients with adenocarcinoma or epidermoid carcinoma of the esophagus were entered into a phase II trial evaluating the combination of cisplatin 100 mg/m2 intravenously (IV) day 2, vinblastine 1.6 mg/m2 IV days 1 to 4, and mitoguazone (MGBG) 500 mg/m2 IV days 1 and 8. Twenty-nine patients (group A) were newly diagnosed with local-regional disease only and were candidates for transhiatal esophagectomy (THE). These patients received two courses of chemotherapy at 3-week intervals prior to surgery. Response was assessed by measuring changes in the primary tumor length and depth on serial biphasic contrast esophagrams and comparing this result with tumor measurements obtained from the surgical specimen. Complete (CR) and partial responders (PR) received three additional postoperative cycles. Seven patients had recurrent or metastatic disease (group B) and were treated every 4 weeks until disease progression. Of 34 patients evaluable for response, there was one pathologically confirmed CR and 15 PRs (47%). This consisted of 12 of 27 (44%) group A patients (seven of 11 epidermoid, five of 16 adenocarcinoma) and four of seven (57%) group B patients (two of four epidermoid, two of three adenocarcinoma). Toxicity included leukopenia in one third of treatment courses and thrombocytopenia in 21%. Nausea and vomiting occurred in 60% of patients, diarrhea in 18%, transient nephrotoxicity in 18%, peripheral neuropathy in 12%, and ototoxicity in 3%. Twenty-five group A patients underwent resection. Four chemotherapy nonresponders (NR) and one PR had known disease left at surgery; all others (80%) had gross total removal of their disease. The median survival time (MST) of the 29 group A patients was 14 months, with 21% alive at 36 months. The MST of group A chemotherapy responders was 15 months compared with 9 months for NRs (P = .032). Initial sites of recurrence in 14 patients were local-regional in six, distant only in six, both local-regional and distant in two. This regimen, administered in maximally tolerated doses, was active in epidermoid and adenocarcinoma histologies, recurrent disease and newly diagnosed patients. However, nearly all responses were PRs and the MST of resected patients was similar to a prior series of patients treated with esophagectomy alone. Observations from this pilot trial and those of others have led to a follow-up study, in progress, evaluating intensive preoperative chemotherapy and concurrent radiation therapy (RT).

One hundred ninety-one patients with advanced epithelial ovarian carcinoma were treated with either a combination of doxorubicin and a five-day course of cisplatin alternating with cyclophosphamide and hexamethylmelamine orally for 14 days (CHAP-5) or cyclophosphamide and cisplatin both administered intravenously (IV) on a single day at 3-week intervals (CP). At a median follow-up time of 45 months, treatment with each of these combinations resulted in the same remission rates (80% and 74%, respectively) and exactly the same progression-free survival and overall survival (median, 26 months). Despite adequate hydration, more renal toxicity was encountered in the CP-treated patients than in those who received CHAP-5. Disabling neurotoxicity and severe myelosuppression were encountered more frequently in the patients treated with CHAP-5. Because the toxicity was lower and CP treatment required shorter hospitalization, the single-day regimen was considered preferable for future use. The Karnofsky index was the only independent predictor for response, whereas both this index and the size of residual tumor before chemotherapy were predictive of survival. After correcting for other prognostic factors, it was determined that tumor size associated with improved survival was less than 1 cm. The site of metastases in International Federation of Gynecology and Obstetrics (FIGO) stage IV patients did not influence survival within this category. The results of this study confirm our previous findings that patients with microscopic remnants at second-look have a survival similar to that of patients who are histopathologically free of disease. This makes the significance of so-called pathologically confirmed complete remission questionable. The survival benefit of debulking surgery performed during chemotherapy seems only minimal for patients in whom debulking has already been attempted before treatment. Like others, we have found the CP regimen to have a good therapeutic index.

Weekly high-dose methotrexate with leucovorin rescue and vincristine (HDMTX) and doxorubicin was administered as adjuvant postoperative therapy to 46 patients with a diagnosis of conventional high-grade nonmetastatic osteosarcoma of an extremity between July 1976 and December 1981. The primary lesions were managed by wide or radical amputation (26 patients) or by limb-sparing resection in 20 selected patients. The margins of the resections were retrospectively classified as marginal in three, wide in 16, and radical in one. The 5-year relapse-free survival (RFS) for all patients is 59% (95% confidence interval [CI], 43%, 74%) and overall survival is 78% (95% CI, 65%, 91%). The RFS for patients initially having a limb resection procedure is 55% (95% CI, 32%, 77%) compared with 62% (95% CI, 43%, 81%) for those initially having amputations (P = .52). Using multivariate analysis, the only significant prognostic variables that predicted RFS of greater than or equal to 3 years, were the presence of moderate to marked lymphocytic infiltration of the primary tumor (P less than .002), primary site outside of the proximal humerus (P less than .005), and the absence of a predominance of osteoblastic pattern in the primary tumor (P less than .03).

The development of a new multidrug chemotherapy regimen for primary brain tumors was based upon the cellular heterogeneity within individual tumors, the Goldie-Coldman and Price-Goldie-Hill hypotheses, and known agonistic effects of certain drug combinations and sequences. Eight drugs (vincristine [VCR], hydroxyurea, procarbazine, CCNU, cisplatin, cytosine arabinoside [Ara-C] high-dose methylprednisolone, and either cyclophosphamide or dacarbazine) were administered within 12 hours in an attempt to minimize myelosuppression. Courses were repeated at 2- to 4-week intervals. The regimen was devised to include lipid and water soluble drugs, polar and nonpolar agents, phase-specific and cell-cycle independent agents, and antineoplastics with different mechanisms of action. More than 330 courses of the regimen were administered to 107 children with brain tumors whose tumor had recurred or had been incompletely resected at diagnosis. Tumor response according to protocol-specified criteria and independent review was evaluable in 78% of the patients. After just two cycles of chemotherapy and within a 4- to 6-week interval, 50% had an objective tumor response including 15.5% who had a complete response (CR). Nephrotoxicity and high-frequency hearing losses were noted after three to five courses of therapy in approximately half of the patients. Transfusions with red cells or platelets and use of antibiotics for fever and neutropenia were required in 10% to 25% of patients. The regimen appears satisfactory for preradiation chemotherapy in newly diagnosed patients with residual tumor after surgery, but it must be compared with standard therapeutic approaches in prospective controlled trials before its relative value can be established.
Estrogen receptor in malignant melanoma.

The significance of an estrogen binding protein (ER) in malignant melanoma remains controversial. We have prospectively assayed for ER on 141 patients with malignant melanoma and correlated the presence of the ER with known prognostic variables. The overall incidence of ER was 43%. The incidence of ER in males was 38.7% and 50% in females (not significant). There is an increased incidence of ER+ melanoma in women with extremity lesions (P = .08). The disease-free interval (DFI), survival, and recurrent interval were 42.0 +/- 4.0, 52.3 +/- 4.3, 13.7 +/- 1.7 months in ER- patients; 63.7 +/- 11.6, 76.1 +/- 11.4, 26.5 +/- 7.3 months in ER+ patients (1 to 10 fmol/mg cytosol protein), and 69.8 +/- 17.9, 102.7 +/- 27.9, 29.4 +/- 9.9 months in ER+ patients (greater than 10 fmol/mg cytosol); respectively. When ER+ groups were combined, the DFI in women with ER+ lesions was significantly longer than those with ER- tumors (P less than .05). Cox multivariate analysis demonstrated that ER status is a significant variable of survival along with thickness level and nodal status. These observations suggest that ER may be a marker for a more biologically indolent melanoma.

Several case reports have suggested an association of primary mediastinal germ cell tumor (PMGCT) and Klinefelter's syndrome (KS). In an effort to confirm this association, 22 patients with mediastinal germ cell tumors had chromosome studies performed in a prospective fashion. Five patients (22%) had karyotypic or pathologic evidence of KS. All of the patients with KS had germ cell tumors of the nonseminomatous subtype and were relatively young (median age, 15 years). The literature confirms the findings of a young median age (18 years), nonseminomatous subtype, and mediastinal location of the germ cell neoplasm. We conclude that patients with KS are predisposed to the development of mediastinal nonseminomatous germ cell cancers.

Forty remission patients with high-risk acute lymphoblastic leukemia (ALL) underwent matched allogenic bone marrow transplantation (BMT) following preparation with cyclophosphamide and fractionated total body irradiation (TBI). As of March 1987, the median follow-up is more than 3 1/2 years. Thirteen patients are alive (11 relapse free) between 2 and 4 1/2 years post-BMT. Neither age, sex, remission number, prior extramedullary leukemia, nor WBC at diagnosis of ALL was statistically significant as a predictor of relapse-free survival. The development of acute graft-v-host disease (GVHD) in 17 patients was found, with time-dependent Cox regression analysis, to be associated with a significant reduction in post-BMT relapse risk (P = .04) and improved disease-free survival (P = .11). A prospective, randomized trial of maintenance chemotherapy with oral methotrexate and mercaptopurine did not demonstrate improvement in relapse risk or survival for those assigned maintenance chemotherapy (P = .7). These results suggest that allogeneic BMT can result in extended relapse-free survival for some patients with high-risk ALL. More effective preparative chemoradiotherapy and exploitation of the apparent graft-v-leukemia effect may be useful in future trials.
