The efficacy and side-effects of megestrol acetate and medroxyprogesterone acetate in postmenopausal patients with advanced breast cancer were compared in a prospectively randomized study. The dosage of MA was 2 X 80 mg p.o. or
MPA
2 X 500 mg p.o. daily, given as a secondary hormonal treatment, mostly after previous treatment with tamoxifen. Ninety-eight patients entered the study and 92 were evaluable for effect, 48 patients on MA and 44 on
MPA
. Age, main tumor site and prior treatment were not different, but there was a preponderance of ER-negative tumors in the MA group. Responses appeared to be more frequent in the
MPA
-treated group (25% vs. 43%), predominantly in bone lesions, 12% for MA and 45% for
MPA
. Median progression-free survival was comparable, 15 vs. 10 months, and overall survival was not different (20 vs. 16 months). Toxicity was frequent, occurring in 83% vs. 74% of patients: increased appetite, nausea and dizziness in more than 20%, and a preponderance of pyrosis and breathlessness on MA and hot flashes, sweating and tremors on
MPA
. Cushingoid symptoms were present in about a quarter of the patients treated for more than 3 months. The occurrence of thrombo-embolic episodes and cardiovascular events was evenly distributed. Patients on
MPA
had more often increase in body weight, systolic blood pressure and serum creatinine than those treated with MA. It is concluded that
MPA
may be more effective for treatment of
bone metastases
, at the expense of more progestational side-effects. The occurrence of Cushingoid effects is frequent but similar in both arms, while the incidence of cardiovascular or thrombo-embolic events cannot be related to the use of either compound.

A randomized controlled trial was performed to compare the therapeutic results of oral high-dose medroxyprogesterone acetate (HD-MPA) versus mepitiostane (MS) in the treatment of postmenopausal breast cancer.
MPA
was given at three doses of 400 mg orally daily to 47 patients and produced objective responses in 19 cases (40.4%). An objective response was seen in 14 of the 40 control patients given MS at two doses of 10 mg orally daily (35.0%). Among patients with
bone metastases
, 6 of 19 (31.6%) for HD-
MPA
and 2 of 13 (15.4%) for MS showed objective responses. The other merits of HD-
MPA
suggested in the study were improvement in performance status, increase in appetite, and myeloprotective effect.

A randomized controlled trial was made to compare the therapeutic result of oral high-dose medroxyprogesterone acetate (HD-MPA) versus mepitiostane (MS) in the treatment of postmenopausal breast cancer.
MPA
(1200 mg) was given p.o., b.i.d. to 47 patients and produced objective response in 19 of them (40.4%). Objective response was seen in 14 of the 40 control patients given MS p.o., b.i.d. (35.0%). Among patients with
bone metastases
, 6/19 (31.6%) for HD-
MPA
and 2/23 (15.4%) for MS showed objective response. The other merits of HD-
MPA
suggested in the study were improvement in performance status, anabolic effect and myeloprotective effect.

The antitumor effect and side effects of oral high-dose
Medroxyprogesterone acetate
(
MPA
) therapy were studied in 110 patients with advanced or recurrent breast cancer.
MPA
in 200 mg tablets was consecutively administered at a daily dose of 600, 800, 1,000, 1,200, 1,600, 1,800 or 2,400 mg. The overall response rate was 32/110 (29.1%), and the highest response rate was obtained in the 1,200 mg group (38.2%). The response rate by the site of lesion was higher in the soft tissues and also in
bone metastases
. Side effects such as moon face, vaginal spotting and abnormal glucose tolerance was mild and tolerable. Accordingly, from the antitumor effect and side effects, the optimal dose was considered to be 1,200 mg a day. Furthermore, as
MPA
therapy increases appetite and body weight of patients without causing myelopoietic depression, this drug could be used successfully in combination with other chemotherapeutic agents.

The Authors have studied total urinary hydroxyproline (TUH), together with other hematochemical analyses, in 104 patients suffering from advanced breast cancer with or without
bone metastases
. TUH escretion is higher in patients with osseous lesions and, if simultaneous pathologic values of TUH and serum alcaline phosphatase occur, the presence of
bone metastases
is statistically even more probable. Moreover TUH seems to vary in accordance with the clinical response of the disease at osseous level in 46 patients treated with
Medroxyprogesterone acetate
(
MPA
) at high doses, showing itself as a possible marker of not negligible clinical value.

The efficacy of tamoxifen (TAM) was compared to that of progestins (medroxyprogesterone acetate,
MPA
, and megestrol acetate, MA) in the treatment of metastatic breast cancer in postmenopausal women by a quantitative analysis of the results of published randomized clinical trials. Seven studies involving a total of 801 subjects compared TAM with
MPA
. Overall, the frequency of complete and partial response was 9 and 18%, respectively, in the women treated with TAM, versus 9 and 28% in those given
MPA
. Considering complete and partial responses together, the frequency of response was 29% in the TAM group and 39% in the
MPA
group, the corresponding pooled odds ratio (OR) of response being 1.5 (95% confidence interval, CI, 1.1-2.0). The median duration of response was greater in the TAM-treated patients; however, the difference was small (14 vs. 11 months). The probability of response to
MPA
treatment was about 3-fold higher compared with the response to TAM treatment in the subgroup with
bone metastases
(OR 3.4), and 2-fold higher in the subgroup with visceral metastases (OR 2.2), but the difference in the OR estimates was not statistically significant. The response to the two drugs was similar in the subgroup with metastases in soft tissues. Four studies compared TAM with MA, taking in 463 subjects. The overall frequency of complete and partial response was 35% in the patients who received TAM compared with 29% in those treated with MA. The corresponding pooled OR was 0.8 (95% CI 0.5-1.1). Analysis of the results according to site of metastases revealed no significant difference in the frequency of complete or partial response in the two treatment groups.

A 56-year-old woman was referred to Shizuoka General Hospital on April 17, 1992, because of progressive jaundice and massive pleural effusion. A thorough work-up revealed the diagnosis of advanced left breast cancer complicated with direct invasion of the thoracic wall, pleural carcinomatosis, multiple liver and
bone metastases
and obstructive jaundice due to the hilar mass. From a prognostic point of view, we scheduled the treatment course as follows. First, we treated the chief complaints. After emergency drainage and chemo-adhesive therapy of the pleural lesion, percutaneous biliary drainage and radiotherapy were done for obstructive jaundice, followed by internal drainage with self-expandable metallic stents. For the primary cancer of the left breast, standard mastectomy was performed following 57 Gy of radiotherapy.
MPA
was also administered because estrogen-receptor was positive on the histological examination of the resected specimen. To complete the multi-disciplinary treatment, we implanted a vascular access percutaneously via the left femoral artery and started intermittent hepatic arterial infusion chemotherapy on an outpatient basis. The patient was discharged on the 123rd hospital day and is well and active without any symptom 9 months thereafter.

We report a 62-year-old woman with supraclavicular lymph node, pleural and
bone metastases
from breast cancer showing a long-term complete response to combination therapy with 5'-DFUR and
MPA
. A large amount of pleural effusion was drained followed by administration of ADM, which improved the amount of effusion. Treatment with CAF and TAM decreased tumor size, but CAF was abandoned due to severe leukopenia. Mastectomy was performed for local control. However, levels of tumor markers increased progressively. Administration of CMF was tried, but tumor markers continued to increase. Therefore, combined chemoendocrine therapy with 5'-DFUR and
MPA
was undertaken. Levels of tumor markers normalized and a complete response was obtained 13 months after starting this combination therapy. There are no further metastatic lesions evident, and this status has been consistently maintained for more than three years (six years and five months after diagnosis of breast cancer). There were no significant side effects of this combination therapy except for mild weight gain and moon face. This combination regimen with 5'-DFUR and
MPA
is considered useful as a second-line treatment for advanced breast cancer.

A 66-year-old female presented with a swollen lump in the left breast. She was diagnosed as having advanced breast cancer of stage T4N3 (supraclavicular lymph node) M1 (bone). The administration of CEF and TAM failed to improve her condition. After the treatment regimen was changed to combined chemoendocrine therapy with CPA, EPI, 5'-DFUR, and
MPA
, the areas of
bone metastases
were reduced. However,
MPA
caused side-effects (acute obstruction of the lower limb), and thus the treatment was discontinued after 4 months. Subsequently, the treatment combination was changed to CPA, EPI, 5'-DFUR, and fadrozole hydrochloride hydrate. After one year of the treatment, a complete response (CR) was obtained with the disappearance of the supraclavicular lymph node and
bone metastases
. After EPI reached the maximum administration amount, the remaining CPA, 5'-DFUR and fadrozole hydrochloride hydrate oral administrations were continued. As of 3 years and 10 months after the onset of the chemoendocrine therapy, CR has been maintained with suppression of the primary and metastatic lesions, without degrading the patient's quality of life.

We report the case of a 51-year-old female with stage IV advanced breast cancer accompanied by multiple
bone metastases
. A hard mass of about 3.0 cm in diameter was palpated just below the nipple. An excisional biopsy was performed and histological examination revealed infiltrated solid tubular adenocarcinoma. There were no estrogen or progesterone receptors in the tumor. Modified radical mastectomy was performed in October, 1998. Postoperative adjuvant therapy with 10 cycles of CEF therapy was undertaken for one year. Combined chemoendocrine therapy with 5'-DFUR and
MPA
was also conducted for 11 months. Bone scintigraphy showed that all bone metastatic lesions disappeared completely one year after the operation. Mild bone marrow suppression, alopecia and body weight gain were observed as side effects. It is suggested that this combination therapy may be useful for advanced breast cancer patients with multiple
bone metastases
.
