Mini-dose of thalidomide for treatment of primary myelofibrosis. Report of a case with complete reversal of bone marrow fibrosis and splenomegaly.

We report a patient with very advanced myelofibrosis and huge splenomegaly who showed a complete hematological response to low dose thalidomide with reversal of splenomegaly and bone narrow fibrosis after 30 months of the treatment.

Antitumor effect of two oral steroids, mepitiostane and fluoxymesterone, on a pregnancy-dependent mouse mammary tumor (TPDMT-4).

Pregnancy-dependent TPDMT-4 mammary tumors, characterized by requiring estrogen, progesterone, and pituitary hormones for growth, grew continuously in female DDD mice carrying pituitary isografts. The experimental model was used to investigate the antitumor effects of two p.o. steroids, mepitiostane and fluoxymesterone. When tumors implanted with pituitary isografts into the fat-pad reached palpable size, animals received 6 doses/week of 0.1, 0.3, 1.0, and 3.0 mg of either steroid intragastrically. Mepitiostane significantly suppressed tumor growth with regression in 25 and 29 percent of animals at 1.0 and 3.0 mg, respectively, but had no inhibitory effects at other doses. Fluoxymesterone retarted tumor growth during the first week of treatment at 3.0 mg but finally had no inhibitory effects at any doses. Under similar conditions ovariectomy caused tumor regression immediately, and epitiostanol, the parent steroid of mepitiostane, significantly suppressed tumor growth when given in 3 injections/week of 0.5 mg s.c. Tumous had papillary structures and almost lacked secretory activity. A comparison of these findings to those obtained with earlier generations suggests that TPDMT-4 tumors became less sensitive to the antitumor effect of epitiostanol and were able to grow at lower hormone levels with succeeding generations. Morphologically, progression to more cancer and less secretory activity was noticed.

Randomized clinical trial of tamoxifen alone or combined with fluoxymesterone in postmenopausal women with metastatic breast cancer.

A randomized clinical trial was performed to determine if combination hormonal therapy with tamoxifen (TAM) and fluoxymesterone (FLU) was more efficacious than TAM alone for the treatment of postmenopausal women with metastatic breast cancer. Patients failing TAM could subsequently receive FLU. The dose of both drugs was 10 mg orally twice daily. Objective responses were seen in 50 of 119 TAM patients (42%) and 63 of 119 TAM plus FLU patients (53%) (one-sided P = .05). Time to disease progression distributions were better for TAM plus FLU (median, 350 days v 199 days), but the log rank test only approached statistical significance (one-sided P = .07). Duration of response and survival distributions were similar between the two treatment arms. Toxicities, in terms of androgenic side effects, were greater on the TAM plus FLU regimen. Fifty-two patients are evaluable for response with FLU following TAM and 21 (40%) have achieved a response. We conclude that the advantages in terms of response rate and time to progression observed with TAM plus FLU probably represent a biological effect, but are not of sufficient magnitude to justify the routine clinical use of this combination given the lack of survival advantage and side effects encountered.

Reinduction with the same cytostatic treatment in patients with metastatic breast cancer: an Eastern Cooperative Oncology Group study.

PURPOSE: To investigate the therapeutic value of reinduction with the same cytostatic treatment that had been used in induction treatment for women with metastatic breast cancer. MATERIALS AND METHODS: One hundred six women with metastatic breast cancer were given dibromodulcitol (mitolactol), doxorubicin, vincristine, tamoxifen, and fluoxymesterone (DAVTH) for 6 months of induction treatment, then randomized to receive one of two chemotherapy regimens if they had obtained an induction partial response (PR) or no change (NC), or to receive observation versus chemotherapy if they had obtained an induction complete response (CR). Patients were then retreated with DAVTH reinduction after relapse. RESULTS: Seventy-four patients were eligible or had minor reasons for ineligibility. Severe or life-threatening toxicity was documented in 46%, and lethal toxicity in 4%. Eighteen percent had a response on reinduction (zero of 16 induction nonresponders, 15% induction PR, 44% induction CR). The median time to treatment failure (TTF) from reinduction was 3 months, and the median survival duration from reinduction was 14 months. In a logistic model, factors associated with more reinduction responses were observation after induction CR (P = .002) and age greater than 55 years (P = .04). Time since induction was not significant. CONCLUSION: Reinduction of response after treatment failure remains a therapeutic problem. The need for better salvage treatment underlines the importance of developing new regimens.

Postsurgical adjuvant chemotherapy of stage II breast carcinoma with or without crossover to a non-cross-resistant regimen: a Cancer and Leukemia Group B study.

PURPOSE: To compare two cyclophosphamide, methotrexate, fluorouracil, vincristine, and prednisone (CMFVP) regimens with a doxorubicin-based regimen--vinblastine, doxorubicin, thiotepa, and Halotestin (Upjohn, Kalamazoo, MI) (VATH)--in patients with stage II node-positive breast carcinoma. METHODS: Nine hundred forty-five women were treated with a 6-week induction course of CMFVP. They were then randomized to receive one of two consolidation CMFVP regimens: 6-week courses or 2-week courses. Following completion of CMFVP consolidation, patients were again randomized to either continue the CMFVP regimen or to receive six escalating doses of VATH. RESULTS: Among all patients, with a median follow-up time of 11.5 years, there is no statistically significant difference in disease-free survival (DFS) between the two consolidation CMFVP regimens. VATH intensification treatment is statistically significantly superior to CMFVP in terms of DFS (P = .0040). For patients with one to three involved nodes, there is currently no significant difference between VATH and CMFVP; however, among those with four or more positive lymph nodes, there is a significant difference in favor of VATH (P = .0037). There is also improved overall survival with VATH (P = .043; median, > 14 years v 10 years). This difference is also statistically significant in patients with four or more involved lymph nodes, among postmenopausal patients, and among postmenopausal estrogen receptor-positive patients. CONCLUSION: Chemotherapy with crossover to escalating doses of VATH following CMFVP was well tolerated and effective. Inauguration of VATH as a treatment intensification at the eighth month produced a major increase in relapse-free and overall survival. The observation that sensitivity to VATH is retained so long after mastectomy raises questions about the proper duration of adjuvant chemotherapy and lends support to further investigation of cross-over designs in future trials to postoperative adjuvant chemotherapy regimens.

Factors predicting for response, time to treatment failure, and survival in women with metastatic breast cancer treated with DAVTH: a prospective Eastern Cooperative Oncology Group study.

Six hundred twenty-four women with metastatic breast cancer were entered on Eastern Cooperative Oncology Group (ECOG) study EST 2181. Patients were treated with mitolactol, doxorubicin, vincristine (DAV), tamoxifen, and fluoxymesterone (DAVTH). Nine patients were canceled, and 114 were ineligible (half because of concomitant diseases). Among the 501 eligible patients, the overall response rate was 54% (14% complete response and 5% not assessable). The median time to treatment failure (TTF) was 9.0 months, and the median survival was 20.9 months. Multivariate models were fit on a randomly chosen half of the eligible cases and then verified on the other half. About half of the variables that were significant in the models remained significant in the verification data set. In the verification data set the variables that remained significantly associated with lower probability of response were three or more organ sites of disease and lack of nodal metastases; the variables associated with a significantly shorter TTF were liver metastases, estrogen receptor (ER)-negativity, and prior adjuvant therapy. The variables associated with significantly shorter survival were liver metastases, ER negativity, three or more organ sites of disease, and prior adjuvant chemotherapy. None of the variables in the data set had a significant influence on toxicity. The 125 patients aged over 65 years did not have worse toxicity or worse prognosis than younger patients. Ineligible patients had significantly less response but virtually identical TTF curves, survival curves, and toxicities. Therefore, patient discriminants are of paramount importance in predicting the outcome of treatment. Many of the current criteria for eligibility for entry on study may not be justified.

Prospective evaluation of carcinoembryonic antigen levels and alternating chemotherapeutic regimens in metastatic breast cancer.

Ninety-seven eligible and evaluable women with metastatic breast cancer were placed on a prospective clinical protocol to evaluate the use of continuous cyclic therapy with dibromodulcitol, doxorubicin, vincristine, tamoxifen, and fluoxymesterone (DAVTH) v DAVTH alternating with cyclophosphamide, methotrexate, 5-fluorouracil, and prednisone (CMFP); and the use of pretreatment and serial carcinoembryonic antigen (CEA) levels in these patients. Continuous DAVTH and DAVTH/CMFP were equivalent therapies with respect to response rates, time to treatment failure (TTF), and survival. Pretreatment CEA levels were elevated (greater than 5 ng/mL) in 42/97 patients and less than 5 ng/mL in the remaining patients. Patients with elevated pretreatment CEA levels were more likely to be estrogen receptor (ER) positive (P = .006), to have prolonged disease-free intervals (P = .017), to have hepatic (P = .004) and/or osseous (P = .01) metastases, and to have multiple sites of metastatic disease (P = .004). Pretreatment CEA levels did not significantly predict for overall response rates, TTF, or survival; nonetheless, those patients with low pretreatment CEA levels had more complete responses (CRs) (16/55 v 4/42; P = .02). Serial CEA levels during therapy revealed a number of interesting patterns. During the first 4 months of treatment, serial CEA levels in responding patients either (1) progressively declined (15/29 women with elevated pretreatment CEA levels), or (2) initially rose significantly (mean, 243% of pretreatment value) and then declined (14/29 women with elevated pretreatment CEA levels). Peak CEA levels in the latter patients were seen 27 to 135 days following initiation of cytotoxic therapy. In some patients the initial increase in the CEA level was incorrectly interpreted as evidence of impending disease progression. CEA levels frequently increased around the time of clinical disease progression. However, rising CEA levels rarely provided a clinically meaningful lead time before the appearance of other clinical evidence of disease progression. These data suggest that routine pretreatment and monthly serial CEA levels in metastatic breast cancer patients have minimal use in clinical practice. Two further noteworthy findings were observed in this prospective study. First, patients with an unknown ER status had a prolonged median survival when compared with patients with ER positive or negative tumors; this appeared to be related to prolonged disease-free intervals in ER unknown patients. Second, two case of secondary acute leukemia were seen in patients treated with continuous DAVTH therapy.

Comparison of chemotherapy with chemohormonal therapy as first-line therapy for metastatic, hormone-sensitive breast cancer: An Eastern Cooperative Oncology Group study.

PURPOSE: Although hormonal therapy represents standard therapy for metastatic hormone-sensitive disease, many patients receive initial chemotherapy because of the location, bulk, or aggressiveness of their disease. It is uncertain whether simultaneous hormonal therapy provides additional benefit compared with chemotherapy alone. Eastern Cooperative Oncology Group trial E3186 was initiated to explore this question. PATIENTS AND METHODS: Between January 1988 and December 1992, 231 patients with estrogen receptor (ER)-positive or ER-unknown metastatic breast cancer were randomized to receive either chemotherapy (cyclophosphamide, doxorubicin, and fluorouracil ¿CAF) or chemohormonal therapy (CAF plus tamoxifen and Halotestin ¿fluoxymesterone; Pharmacia-Upjohn, Kalamazoo, MI ¿CAFTH) as front-line therapy for metastatic breast cancer. Patients who experienced a complete response to induction therapy either received or did not receive maintenance cyclophosphamide, methotrexate, fluorouracil, prednisone, and TH as a secondary randomization. RESULTS: The response rates (complete response and partial response) of patients who received CAF and CAFTH were similar (69.2% v 68.9%, respectively; P =.99). Time to treatment failure (TTF) was slightly longer for patients who received chemohormonal therapy compared with chemotherapy alone patients (13.4 months v 10.3 months, respectively; P =.087), and TTF was significantly longer in ER-positive compared with ER-negative patients (17.4 months v 10.3 months, respectively; P =.048). However, ER status had no effect on overall survival (30.0 months for CAF v 29.3 months for CAFTH). CONCLUSION: In patients with potentially hormone-sensitive metastatic breast cancer, chemohormonal therapy prolongs TTF for ER-positive patients without improving overall survival.

Combination chemotherapy for metastatic or recurrent carcinoma of the breast--a randomized phase III trial comparing CAF versus VATH versus VATH alternating with CMFVP: Cancer and Leukemia Group B Study 8281.

PURPOSE: We sought to compare three doxorubicin-based therapies for metastatic breast cancer for response frequency, time to treatment failure (TTF), and survival. MATERIALS AND METHODS: Women with metastatic breast cancer who had measurable disease, required laboratory tests, had received no prior chemotherapy for metastases, had a Cancer and Leukemia Group B (CALGB) performance status < or = 2, and provided informed consent were eligible. Treatment included the following: arm I--cyclophosphamide, doxorubicin, and fluorouracil (CAF); arm II--vinblastine, doxorubicin, thiotepa, and halotestin (VATH); and arm III--VATH alternating with cyclophosphamide, methotrexate, fluorouracil, vincristine, and prednisone (CMFVP) on cycles 3, 5, 7, 9, etc. Doses were modified for toxicities. Standard CALGB response and toxicity criteria were used. RESULTS: Between August 1982 and February 1987, 497 women were entered and 491 were treated on study. Pretreatment characteristics were well balanced and the median follow-up duration was 79 months. There were no significant differences in response (complete [CR] plus partial [PR]) at 50% on arm I, 57% on arm II, and 51% on arm III. The median TTFs were 8, 8, and 9 months, respectively, in favor of arm III when compared with arm I (P = .028). The median survival times for treatment arms I, II, and III were 15, 17, and 17 months, respectively. After multivariate regression analyses, only estrogen receptors (ER), performance status, and number of metastatic sites influenced TTF and survival. Leukopenia was the most common grade 3 or 4 toxicity, occurring in 90%, 80%, and 92% of patients per arm, respectively. Lethal toxicities were seen in four, five, and six women, respectively. Overall, there were more grade > or = 3 toxicities on arm II than I, and most occurred on arm III (P = .02). CONCLUSION: The VATH regimen appears similarly effective to the CAF regimen as initial therapy. Alternating CMFVP with VATH did not improve response rate or survival. After accounting for other variables, treatment arm was not related to outcome. New therapeutic regimens are still needed.

Eastern Cooperative Oncology Group randomized trials of observation versus maintenance therapy for patients with metastatic breast cancer in complete remission following induction treatment.

PURPOSE: To investigate the value of maintenance treatment for patients with metastatic breast cancer whose disease is in complete remission (CR). PATIENTS AND METHODS: One hundred ninety-five women (141 eligible) whose disease was in CR or in CR except for bone metastases following six cycles (6 months) of doxorubicin-containing induction treatment were randomized to receive cyclophosphamide, methotrexate, fluorouracil, prednisone, tamoxifen, and halotestin [CMF(P)TH] or observation. In a previous pilot study, patients in CR after 24 months of induction treatment were randomized to continue chemotherapy for 4 more years or stop chemotherapy. RESULTS: Among patients randomized to CMF(P)TH, life-threatening toxicity included leukopenia in 3%, thrombocytopenia in 3%, cardiac in 2%, and diabetes in 1%. The median time to relapse from randomization was 18.7 months on CMF(P)TH and only 7.8 months on observation (P < .0001). The median time to death was 32.2 months on CMF(P)TH and 28.7 months on observation (P=.74). Similar results were seen in the pilot study (median time to relapse, 12.6 and 6.4 months; median survival, 37.7 and 24.2 months; study too small for statistical significance). Maintenance treatment was always the most significant covariate in time-to-relapse models. CONCLUSION: There is definite toxicity associated with CMF(P)TH maintenance treatment. When CR was obtained on induction, maintenance treatment with CMF(P)TH was never significant in survival models. However, maintenance treatment was always the most significant covariate in the time-to-relapse models, which motivates its consideration for appropriately informed patients.

Treatment of myeloma. Comparison of melphalan, chlorambucil, and azathioprine.

A randomized study compared the response of patients with multiple myeloma to chlorambucil, melphalan, and azathioprine. All patients also received a combination of prednisone and fluoxymesterone. Seventy-three of 86 patients entered on the study could have evaluations. The results indicate that melphatan produced more responses than either azathioprine or chlorambucil, but responses to both of these agents were observed. No difference was noted between survival curves for patients with no poor-risk factors as compared to those having at least one poor-risk factor. The only poor-risk factor affecting survival in this group of patients was the blood urea nitrogen level.

Ancillary measures in treatment of myeloma. Use of immune serum globulin, fluoride, or androgen.

We reviewed the efficacy of three agents advocated as ancillary therapy in myeloma patients. Intramuscularly administered immune serum globulin (gamma globulin) was ineffective in preventing infection. Hemoglobin level was improved in some myeloma patients receiving androgens. However, the response rate and the degree of leukopenia or thrombocytopenia were not superior with androgen-melphalan-prenisone combination therapy, as compared with those resulting from the two-drug combination without androgen. A controlled study evaluating androgen plus melphalan has not been done. The long-term administration of fluoride, supplemented by calcium and androgen, induced radiologically apparent bone fluorosis, but strengthening of lytic bone was not observed. Neither objective nor subjective benefit was demonstrated in a controlled study comparing the effects of fluoride (without calcium supplement) with those of the placebo.

Fluoxymesterone-induced gynaecomastia in a patient with childhood aplastic anaemia.

Gynaecomastia is a benign condition characterised by enlargement of the male breast. Drug-induced gynaecomastia merits deep consideration as it may account for as many as 25% of all cases of gynaecomastia in adults. Although the mechanism is not fully clear, some mechanisms include oestrogen-like activities, stimulation of testicular production of oestrogens, inhibition of testosterone synthesis or blockade of androgen action. Anabolic steroids, in particular when used during the pubertal stage, may cause significant irreversible gynaecomastia. We report a case of 28-year-old Filipino man with persistent gynaecomastia from fluoxymesterone used for aplastic anaemia during his prepubertal stage. Hormonal work ups for gynaecomastia all turned out normal, thus isolating the drug as the cause. The patient was unable to undergo breast reconstruction surgery due to haematological contraindications, but eventually referred to psychiatry for counselling. This case will highlight the paradoxical effect of androgenic steroid used during childhood on male breast proliferation during puberty.

Long-term results of treatment with low-dose fluoxymesterone in constitutional delay of growth and puberty and in genetic short stature.

This prospective study was designed to assess growth response, side effects, other possible long-term effects, and final adult height in boys treated with the oral androgen, fluoxymesterone. From 1973 to 1984, eighty-two short boys (71 with constitutional delay of growth and puberty [CDGP] and 11 with genetic short stature [GSS]) were treated with daily oral doses of 2.5 mg of fluoxymesterone from 6 to 60 months. Final height assessment was made from 1989 to 1991. A group of 34 untreated boys (26 with CDGP and 8 with GSS) were also followed to assess the accuracy of the Greulich-Pyle and Bayley-Pinneau (GP-BP) and sexual maturity index height prediction methods. During treatment, each patient had a 1.7- to 2.5-fold increase in linear growth velocity. Accelerated velocity (over baseline) continued as long as the bone age was less than 14 years. No adverse androgenic effects (or undue acceleration of puberty) were observed. Final height exceeded pretreatment predictions for CDGP + GSS by 6.1 +/- 3.5 (SD) cm (GP-BP) and 5.4 +/- 3.2 cm (sexual maturity index). It is concluded that a daily oral dose of 2.5 mg of fluoxymesterone can be used to accelerate linear growth in boys with CDGP and GSS when needed to alleviate emotional problems secondary to slow growth and short stature without fear of compromising final adult height.

A randomized phase II trial of aminoglutethimide and hydrocortisone versus combined aminoglutethimide, hydrocortisone and fluoxymesterone in advanced breast cancer.

Fifty postmenopausal women with advanced breast cancer were included in the following randomized phase II trial: 25 patients received aminoglutethimide 1000 mg and hydrocortisone 40 mg daily. Twenty-five patients received aminoglutethimide 1000 mg, hydrocortisone 40 mg and fluoxymesterone 20 mg daily. The two groups of patients were comparable in respect to the most important pretreatment characteristics. The majority of patients in both groups had bone lesions. There was a history of response to tamoxifen in all the cases and 17 patients had positive estrogen and progesterone receptors. The evaluation of response was based on the system adopted by the UICC. In the aminoglutethimide-hydrocortisone group, 16 (64%) patients obtained a partial remission, 3 (12%) remained stable and 6 (24%) had progressive disease. In the combination treatment group, 17 (68%) patients obtained a partial remission, 3 (12%) remained stable and 5 (20%) developed progressive disease. The median duration of partial remission and stabilization of the disease was 9 and 7 months respectively in both groups.

Effect of low-dose androgen and zinc sulfate on sperm motility and seminal zinc levels in infertile men.

Beneficial effects of zinc therapy in some infertile patients with low seminal zinc concentrations and decreased sperm motility have been reported recently. The effects of zinc therapy, low-dose (5-10 mg/day) androgen therapy, and combination therapy of both zinc and low-dose androgen, on sperm motility and seminal zinc concentration were studied in patients referred to the andrology clinic. Low-dose androgen therapy increased seminal zinc concentrations and sperm motility, only when pretreatment seminal zinc concentrations were low. Furthermore, patients with low seminal zinc concentrations and poor sperm motility showed greater improvement of sperm motility and seminal zinc levels in response to zinc sulfate with fluoxymesterone than did fluoxymesterone alone or zinc sulfate alone, possible due to a synergistic effect of zinc and androgen.

The effect of orally administered androgens on sperm motility.

The administration of oral androgens increased sperm motility to normal in 30 (52%) of 58 men whose impaired motility was the only defect in their semen quality. Their ejaculate volume, sperm count, and morphology were not benefited. Suppression was infrequently seen and appeared to be transient. Pregnancies were documented in 15 (26%) of the 58 couples studies. However, communication regarding this matter was made with only 39 of the 58 couples. The benefical effect from a single course of androgen is likely to persist. However, if a pregnancy does not ensue, semen analysis should be repeated to determine if additional medication is necessary. Pretreatment serum testosterone determinations were not helpful in determining those men who would most likely benefit from therapy. No appreciable benefit was noted in the semen quality of the 35 subfertile men identically treated who, in addition to poor sperm motility, had other defects in their semen.

Hormone stimulation and chemotherapy in advanced prostate cancer: preliminary results of a prospective controlled clinical trial.

Preliminary evidence suggests that the sensitivity of endocrine-dependent neoplasms to chemotherapy may be enhanced by transient hormonal stimulation of tumor growth. To test this concept, we are conducting a prospective controlled trial in men with stage D2 prostate cancer who have relapsed following orchiectomy. All patients are continuously treated with aminoglutethimide and hydrocortisone to lower adrenal androgen secretion plus cyclic chemotherapy. Patients in the stimulation arm receive, in addition, the synthetic androgen fluoxymesterone for 3 days before and on the day of chemotherapy. Of 41 patients entered to date, 26 are evaluable. Twenty-one (81%) obtained either an objective remission or stabilization of disease with a mean duration of 9+ months and 10 patients still responding. Thus far, the response rate is similar in the control and stimulation groups. Androgen administration was associated with a rise in acid phosphatase and usually a modest flare of symptoms except for 2 patients who developed spinal cord compression. These preliminary data indicate that the combination of aminoglutethimide and chemotherapy has a potent antitumor effect on advanced prostate cancer refractory to orchiectomy. A large number of patients and a longer follow up are needed to assess whether transient androgen administration potentiates the effect of chemotherapy.

Induction chemotherapy of dibromodulcitol, Adriamycin, vincristine, tamoxifen, and Halotestin with methotrexate in metastatic breast cancer: an Eastern Cooperative Oncology Group Study (E1181).

Patients who have metastatic breast cancer are seldom curable. Chemotherapy given by conventional doses and schedules generally produces complete remissions in 10% to 20% of patients. This study sought to determine 1) whether a combination of dibromodulcitol, Adriamycin, vincristine, tamoxifen, Halotestin, and methotrexate with leucovorin rescue (DAVTHML) can produce a complete remission rate of 50%; and 2) the toxicity of this combination in patients with chemotherapy-naive metastatic breast cancer. Patients were treated with six 28-day cycles of DAVTHML induction chemotherapy consisting of dibromodulcitol, 135 mg/m2 perorally days 1 to 10; Adriamycin 45 mg/m2 intravenously day 1; vincristine, 2 mg intravenously day 1; tamoxifen and Halotestin, 20 mg perorally daily; methotrexate, 800 mg/m2 intravenously days 15 and 22; and leucovorin, 15 mg/m2 perorally every 6 hours for 9 doses, starting 4 hours after methotrexate. After induction, patients who had stable disease or a partial response were treated with a cyclophosphamide, methotrexate, and 5-fluorouracil-based regimen (CMF). Patients in complete remission were treated with three additional cycles of DAVTHML after achieving complete remission and then observed off therapy until relapse, when DAVTHML was to be given again. Fifty-eight patients were included in this study. During induction, 26% of eligible patients experienced a complete remission; overall response rate was 80%. The median time to treatment failure and the median survival time of eligible patients was 11.1 and 24.0 months, respectively. This did not change significantly when all the patients were included in the evaluation. The 3-year and 5-year survival rates were 37% and 11%, respectively. Ninety percent of the eligible patients experienced grade III or IV toxicity. They were leukopenia (75%), anemia (20%), thrombocytopenia (20%), and vomiting (17%). No lethal toxicity was documented during therapy; however, 1 patient later died of myelodysplastic syndrome induced by dibromodulcitol. The overall response and complete remission rates from our study were encouraging. The toxicity of DAVTHML was tolerable, with the exception of myelodysplastic syndrome from dibromodulcitol. The concept of using mid-cycle nonmyelosuppressant agents to increase complete remission rate is feasible.

Adjuvant therapy of stage II breast cancer treated with CMFVP, radiation therapy and VATH following lumpectomy. A pilot trial.

A pilot study was undertaken to assess the feasibility, toxicity, and efficacy of combined radiation therapy and chemotherapy in the adjuvant treatment of node-positive. Stage II patients with breast carcinoma who had undergone lumpectomy. Therapy consisted of three phases, starting with a six-week CMFVP (cyclophosphamide, methotrexate, 5-fluorouracil, vincristine, prednisone) induction, followed by radiation therapy to the breast, and concluding with four cycles of VATH (vinblastine, Adriamycin, thiotepa, Halotesin). Twenty-seven patients were entered with an average age of 51.5 years (median 50 yrs) and a mean follow-up of 46.2 months. Twenty-three patients (85.2%) are alive and 19 (70.3%) disease free. There were no ipsilateral local recurrences. Cosmetic results were good to excellent in 26/27 patients. The doses of VATH were not compromised by the prior therapy. The regimen was found to be tolerable and is a reasonable approach in the adjuvant treatment of this particular patient population.
