We performed a prospective randomized trial of a high-dose chemotherapy regimen v standard cisplatin-based chemotherapy in poor prognosis nonseminomatous germ-cell cancer patients. The high-dose regimen consisting of twice the standard dose of cisplatin (P), along with vinblastine (Ve), bleomycin (B), and the epipodophylotoxin etoposide (VP-16) (V) (PVeBV) was compared to the classic regimen with normal dose cisplatin, vinblastine, and bleomycin (PVeB). Eligibility criteria included large abdominal masses, liver metastases, multiple pulmonary metastases, brain metastases, marked elevations in serum tumor markers (alpha-fetoprotein greater than 1,000 ng/mL or the beta-subunit of human chorionic gonadotropin greater than 10,000 mIU), unfavorable histology (pure choriocarcinoma), or extragonadal germ-cell tumors. Fifty-two consecutive patients with poor prognostic features were randomized to receive either PVeBV or PVeB. The median follow-up is 4 years. Treatment with the high-dose regimen increased the complete remission rate (88% v 67%, P = .14) and was associated with a lower relapse rate (17% v 41%, P = .2). The median survival of patients receiving standard therapy was 30 months, while the median survival for patients receiving the high-dose regimen has not been reached. Actuarial 5-year survival for patients treated with the high-dose regimen is 78%, compared with 48% for patients receiving standard therapy (two-sided Mantel-Cox test = .06). Disease-free survival was also superior for patients randomized to PVeBV (P = .03). Sixty-eight percent of patients (23 of 34) randomized to PVeBV are alive and continuously disease-free, compared with 33% (six of 18) for PVeB (P = .02). The major difference in toxicity between the high-dose regimen and standard therapy was the severity of myelosuppression and the incidence of severe hearing loss. Ninety-one percent of patients treated with PVeBV had a WBC count less than 1,000/microL, compared with 50% of patients receiving PVeB (P less than .05). Hearing aids were recommended for 12 patients who received PVeBV and two who received PVeB. The increased effectiveness of the PVeBV regimen in poor prognosis germ-cell cancer patients may relate to the double-dose cisplatin, the addition of VP-16, or to a synergistic effect of these two drugs.

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.

This study was designed to assess the role of dosage of chemotherapy for treatment of metastatic breast cancer. One hundred thirty-three patients without prior chemotherapy for metastatic disease were randomly allocated to receive two different dose levels of cyclophosphamide (C), methotrexate (M), and fluorouracil (F), administered intravenously (IV) every 3 weeks. Patients were stratified by sites of disease (visceral, bone, or soft-tissue dominant) and by interval from primary surgery to first recurrence. Doses on the higher-dose arm were 600 mg/m2 (C,F) and 40 mg/m2 (M) with escalation if possible; doses on the lower-dose arm were 300 mg/m2 (C,F) and 20 mg/m2 (M) without escalation. Patients who failed to respond to lower-dose CMF were crossed over to the higher-dose arm. Patients randomized to the higher-dose arm had longer survival measured from initiation of chemotherapy (median survival, 15.6 months v 12.8 months, P = .026 by log-rank test), but the effect of dose was of borderline significance (P approximately 0.12) when adjusted for a chance imbalance between the two arms in the time from first relapse to randomization, using the Cox proportional hazards model. Response rates (International Union Against Cancer [UICC] criteria) for patients with measurable disease were higher-dose arm: 16/53 (30%) and lower-dose arm: 6/53 (11%), (P = .03). Only one of 37 patients responded on crossover from the lower- to the higher-dose arm. Patients experienced more vomiting, myelosuppression, conjunctivitis, and alopecia when receiving higher doses of chemotherapy. A series of 34 linear analogue self-assessment scales were used to make detailed quality of life assessments on a subset of 49 patients. These scales confirmed greater toxicity in the immediate posttreatment period, but also a trend to improvement in general health and some disease-related indices, in patients receiving higher-dose chemotherapy. This trial suggests that better palliation is achieved by using full-dose chemotherapy.

Twenty-two patients with metastatic melanoma were treated with a chemotherapy regimen consisting of two cycles of induction therapy with vinblastine, bleomycin, and cisplatin, followed by maintenance therapy with dacarbazine and dibromodulcitol. A 17% response rate was noted in this patient group, with a median survival of 40 weeks. Objective responses were limited to cutaneous, nodal, pulmonary, and one adrenal site of metastatic disease. Toxicity was acceptable and was limited to myelosuppression and nausea with emesis. Further study appears warranted to define the optimal treatment plan for metastatic melanoma.

Surgery and radiation therapy are major treatments for carcinoma of the uterine cervix. However, there has been little improvement in survival recently. Since 1982, we have introduced multiagent chemotherapy consisting of cis-platinum, vincristine and peplomycin (CVP) to control systemic disease and to do cytoreduction prior to operation and/or radiation therapy. Our results are as follows. Thirty-one patients have been treated with CVP. Among eleven patients initially treated with CVP, 7 patients responded well to this regimen alone, including three patients who entered complete clinical remission. This indicates that this regimen is effective against carcinoma of the uterine cervix. Two patients who were thought to be candidates for radical hysterectomy became able to have less extensive surgery following CVP treatment. It is difficult for this CVP combination to control bulky tumors within previously radiated fields, probably because of poor vascularity due to pelvic fibrosis caused by radiation. Metastatic disease were also able to be controlled by this combination especially in two patients with pulmonary metastases. Nausea, vomiting and mild myelosuppression were frequently encountered, but they were tolerated well by the patients. However, great care must be taken in using peplomycin when the cumulative dose becomes large.

From 1981 to 1986, 17 patients with resected small cell lung carcinoma (SCLC) staged as I or II according to the new TNM classification were recruited for a prospective study to evaluate the effectiveness of surgery and postoperative chemotherapy (plus locoregional radiotherapy only when a nonradical resection was accomplished) in the treatment of early stages of the disease. Six patients received full protocol chemotherapy (6 courses) and 8 a mean of 79.1% of the planned courses. Three patients received non adjuvant treatment. Locoregional radiotherapy for residual disease was administered in 2 cases. One patient died for myelosuppression due to chemotherapy and 10 for recurrences of cancer, all within the 20th postoperative month. Metastases accounted 80% of overall recurrences. Six patients were alive and tumor-free at 18, 22, 39, 44, 47 and 51 months from resection. Actuarial observed 3-year survival was 32%.

Thirty-five patients with disseminated skeletal metastases from a variety of tumor types underwent clinical trial of samarium-153 ethylenediaminetetramethylene phosphonate (153Sm-EDTMP) on a day-patient basis. Individual beta radiation dosimetry was based on pharmacokinetic studies of a 20 mCi tracer dose of 153Sm-EDTMP. The retained skeletal activity varied unpredictably from 40% to 95% of the administered dose, but in all patients greater than 98% of the nonosseous activity was cleared in the urine within 6 hours. Prospective calculation of radiation dosimetry in each patient permitted an accurate dosage schedule based upon total red marrow exposure, starting at 100 cGy and escalating to 280 cGy to define the dose-limiting myelotoxicity. Pain was relieved in 22 of 34 evaluable patients (65%) for periods ranging from 4 to 35 weeks, following a single administration of 153Sm-EDTMP. Recurrence of pain responded to retreatment with 153Sm-EDTMP in five of nine patients. The dose-limiting toxicity was myelosuppression manifested particularly by delayed thrombocytopenia. Platelet counts less than 100 x 10(9)/L occurred in 42% of courses when bone marrow radiation absorbed dose exceeded 200 cGy. Myelosuppression was transient and platelet counts had recovered to pretreatment levels within 10 weeks of treatment. 153Sm-EDTMP is effective for the amelioration of pain due to disseminated skeletal metastases particularly with carcinoma of breast or prostate where 83% of patients experienced pain relief. In 15 of the 34 evaluable patients there was evidence of stabilization or regression of skeletal metastases on radiographs and follow-up technetium-99m methylene diphosphonate (99mTc-MDP) bone scans.

Thirty-seven patients with widely metastatic malignant melanoma were treated with one of three chemotherapy regimens, incorporating high-dose dacarbazine (DTIC). The chemotherapy was followed by autologous bone marrow rescue which was harvested under local anesthesia in 25 of the patients. The three regimens comprised a 24-hour infusion of DTIC (Regimen A for patients less than 45 years of age, 4.3 to 10.5 g/m2; B, if greater than 45 years of age 2.7 to 4.0 g/m2; and later C, if greater than 45 years of age 7.0 to 8.0 g/m2). The second alkylating agent was given at +8 and +16 hours from the start of DTIC. The total doses of the melphalan ranged from 60 to 130 mg/m2 for Regimen A and 30 to 40 mg/m2 for Regimen B. Ifosfamide 5.0 to 8.0 g/m2 was given instead of melphalan in Regimen C. The response rates for the regimens were 81% (25% CR) for A, 27% (11% CR) for B, and 20% (with no complete responders) for Regimen C. There was no statistically significant difference between the three regimens for survival with a median value of 6 months. One of the 16 patients treated with the very high dose Regimen A died of septicemia and three of ten patients in Regimen C died within the first 2 weeks of treatment. There was statistically significant greater myelosuppression, stomatitis, and diarrhea in the very high dosage DTIC and melphalan (Regimen A) compared with the other two regimens. No significant difference in response rate or toxicity was observed for the different dosages escalated within each of the three regimens. Although hematologic and gastrointestinal toxicity were very severe, no unusual side effects were noted except for one episode of severe acute renal failure in the high-dose DTIC and melphalan, Regimen A. Responses occurred mainly in nonvisceral, nodal, and cutaneous sites and occasionally in pulmonary metastases. The Karnofsky performance improved 4 to 6 months after treatment notably with the high-dose DTIC and melphalan therapy. No survival benefit for the combination chemotherapy despite the high dosages was detected and such an approach currently cannot be recommended.

One hundred seventy-three patients were treated 256 times with chemotherapy supported by autologous bone marrow transplantation during the past 9 years. The two most commonly used protocols were (cyclophosphamide 1,600-2,400 mg/m2 + adriamycin 80 mg/m2 + ACNU 3 mg/kg) and (cyclophosphamide 1,600-2,400 mg/m2 + adriamycin 100 mg/m2 + CDDP 100-150 mg/m2). Among 115 patients in the therapeutic setting in which two courses were usually given, 75 were evaluable and the overall response rate was 42.7% with 12.0% CR rate. Breast and pediatric groups responded well; the response rate in breast cancer was 67.9% with 21.4% CR rate. Two patients with breast cancer who had multiple distant metastases and 2 pediatric patients are now alive with NED after 5 years of the treatment and seem to have been cured. The results in adjuvant settings have also been quite promising, e.g., 79.4% 5-year survival probability among breast patients mainly in stage III. Although drops of blood cell counts to the nadirs (WBC counts: less than 100-300) could not be prevented, the periods of myelosuppression appeared to have been effectively shortened so that the patients could be safely managed with intensified general supportive measures. Platelet counts are usually less affected, but the recovery is slower than for WBC counts. There were 13 patients who died within 10 weeks of the initiation of the treatment. Two of them succumbed to sepsis, and progressive disease was the cause of death in 8 patients whose terminal phases were undoubtedly affected by some infectious problems. We have shown that there are inverse relationships between infused numbers of CFU-GM and marrow recovery judged by the duration of neutropenia and the time required for neutrophils to recover over 500. Our recent laboratory experiments testing CFU-E, BFU-E and CFU-Mk in addition to MNC counts and CFU-GM showed that vulnerabilities of marrow progenitors seem to differ from cell lineage to cell lineage. This must therefore be taken into careful consideration in pursuing marrow transplantation.

In this phase II multicenter trial, 67 evaluable patients with advanced measurable gastric carcinoma were treated with a combination of etoposide, Adriamycin (doxorubicin; Adria Laboratories, Columbus, OH), and cisplatin (EAP). The overall response rate was 64%, including 21% complete responses (CRs). In 55 patients with metastatic disease, 31 responses (51%) including eight CRs (15%) were achieved. Responses were seen in all metastatic sites, but the response rate was lower in patients with peritoneal carcinomatosis. In 12 patients with locoregional disease, six CRs and six partial responses (PRs) were observed. Eight CRs (three and five in patients with metastatic and locoregional disease, respectively) were pathologically confirmed. The overall median response duration was 7 months; it was 16 months for patients achieving CR (22 months for pathologically confirmed CR [pCR]), and 6 months for PR. The median survival time for all patients was 9 months, for the patients who achieved CR 17 months, for pCR 23 months, and for PR 9.5 months. Median survival time for all patients with metastatic disease was 8 months, and for locoregional disease 12.5 months. Six patients (9%) (four local, two metastatic disease) were alive at 2 years, and four patients are alive and disease free at 35+ to 56+ months. Main toxicities were leukopenia and thrombocytopenia, with 64% of patients developing grade 3 to 4 myelosuppression and 12% severe infections. Nonhematologic toxicities of World Health Organization (WHO) grade 4 were not observed.
