Seventy-eight advanced breast cancer patients, most of whom had had prior treatment, were treated with the synthetic antiestogen tamoxifen. The overall objective response rate was 27% (21/78). An additional 19% (15/78) showed disease stabilization. Sixty-seven percent (14/21) of the responses were in soft tissue sites, 24% (5/21) on bony sites and one each occurred in liver and nodular lung disease. Forty percent of patients with soft-tissue disease alone responded, while less than 10% of patients with visceral disease showed responses in visceral sites. The response rate was 28% among patients with a known positive estrogen receptor (ER) assay. It was 21% among patients who had previously received cytotoxic drugs. Toxicity was mild and was seen in nausea and vomiting, hot flushes and vaginal bleeding, and occasional myelosuppression. One patient was withdrawn from the study because of a rash. In two patients the disease flared, once with concomitant hypercalcemia. Tamoxifen is a useful agent for advanced breast cancer even in some patients with visceral disease.

Eighty previously treated postmenopausal women with metastatic breast cancer were randomized to receive fadrozole (CGS 16 949A), a new aromatase inhibitor, 1 or 4 mg orally per day. Seventy eight patients were evaluable for toxicity and response. Only mild to moderate toxicity, namely hot flushes (28%), nausea and vomiting (13%), fatigue (8%) and loss of appetite (5%) occurred. Complete response was documented in 10% and partial response in 13% of patients with 45% having a no change status for at least 2 months. The median time to treatment failure is 4.1 months. The median survival is 23.7 months. The median survival is 23.7 months. The response and survival in patients with estrogen receptor positive and estrogen receptor unknown disease were not significantly different. Neither response nor survival was significantly different between the patients receiving 1 or 4 mg of fadrozole per day. Fadrozole is a well tolerated, effective second line treatment for women with metastatic breast cancer.

Tamoxifen, a non-steroidal antioestrogen, represents a significant advance in treatment of female breast cancer. In trials of tamoxifen as postsurgical adjuvant treatment of early breast cancer, disease-free survival is consistently prolonged, representing an enhanced quality of life in association with tamoxifen's favourable adverse effect profile. Moreover, overview analysis indicates a survival benefit of approximately 20% at 5 years for all women, most clearly evident in women over 50 years, while a survival benefit independent of menopausal, nodal or oestrogen receptor status has been demonstrated in some individual trials. Thus, for postmenopausal women, tamoxifen is clearly optimal adjuvant treatment, although the relative benefit of adjuvant chemotherapy in node-negative patients requires clarification. A survival benefit for women under 50 has not been clearly demonstrated in overview analysis, but is not precluded by these rather limited data, and adjuvant treatment of premenopausal women with tamoxifen may also warrant serious consideration. Response rates to tamoxifen in advanced breast cancer are around 30 to 35%, increasing with patient selection for oestrogen receptor positivity. Tamoxifen must be regarded as first-line endocrine treatment in postmenopausal women, and may represent an alternative to first-line ovarian ablation in premenopausal women. An emergent role in primary therapy of elderly and frail patients with operable disease is apparent. Tamoxifen is also of benefit following surgery in male breast cancer, and may have a role as first-line endocrine treatment. Tamoxifen also has a potential role in other hormone-sensitive malignancies such as pancreatic carcinoma, and in treatment of benign breast disease. Finally, tamoxifen has a place in treatment of male and female infertility. because of adverse effects is rarely necessary. The most frequent adverse effects are related to the drug's anti-oestrogenic activity, and include hot flushes, nausea and/or vomiting, vaginal bleeding or discharge, and menstrual disturbances in premenopausal patients. Thus, tamoxifen continues to play a major role in management of female breast cancer in both early and advanced stages of disease, with a place also in treatment of male breast cancer and of infertility.

In a randomized, prospective trial, 199 previously untreated patients with Stage D2 prostatic cancer were treated with 3 mg/day diethylstilbestrol (DES) or 1 mg/day leuprolide acetate, a luteinizing hormone releasing hormone analog. Both DES and leuprolide suppressed testosterone to the desired castrate levels. Objective measures of disease, such as acid phosphatase levels, and subjective measures, such as bone pain, performance status, and mobility, showed similar decreases in both groups. No progression of disease was seen in 86 per cent of the leuprolide-treated group, compared with 85 per cent of the DES-treated group. The time to disease progression, development of adverse reaction requiring discontinuation of treatment, or death was identical for the two groups. Hot flashes were more common with leuprolide than with DES. Gynecomastia and breast tenderness, nausea and vomiting, and peripheral edema occurred more often in the DES group. Of those taking DES, 13 per cent discontinued treatment because of side effects, compared with 3 per cent of those taking leuprolide.

A phase I study of benzisoquinolinedione (amonafide) was conducted in 30 patients with advanced solid tumors refractory to conventional therapy. The starting dose was 10 mg/m2/day X 5 days and the highest tolerated dose was 625 mg/m2/day X 5. The daily dose was mixed in 100 ml of normal saline and infused over 30-60 minutes. The dose-limiting toxicity was myelosuppression with nadirs of blood counts reached on Day 15 and recovery by Day 21-28. Other side effects included mild nausea and vomiting, mild phlebitis, skin rashes, and alopecia in some patients. A majority of the patients experienced dizziness, tinnitus, and hot flushes occurring predominantly at the higher dose levels. These were related to the rate of drug infusion and resolved on prolonging the infusion to 60 minutes. Pharmacokinetic studies of amonafide revealed a monoexponential plasma disappearance curve with a mean half-life of 3.5 +/- 1.9 hours. The recommended dose of amonafide for phase II studies in solid tumors is 400 mg/m2/day X 5 for good-risk and 300-320 mg/m2/day X 5 days for poor-risk patients with courses repeated at 21-28-day intervals.

The triphenylethylene antiestrogen toremifene is a chlorinated derivative of the antiestrogen tamoxifen, an agent which has been widely and successfully used in the treatment of breast cancer. Clinical trials investigating the efficacy of toremifene as first-line endocrine therapy in postmenopausal women with advanced breast cancer (estrogen receptor status positive or unknown) have shown this drug to have similar antitumour activity to that of tamoxifen. In multicentre comparative trials, objective responses (complete and partial) occurred in 20 to 29% of patients treated with toremifene (60 to 240 mg/day) and in 19 to 37.5% of tamoxifen (20 or 40 mg/day) recipients. The duration of response, time to disease progression and median overall survival time were generally similar in both treatment groups. Toremifene is well tolerated. Most drug-related adverse effects are mild or moderate in severity and rarely necessitate discontinuation of therapy. The tolerability profile of toremifene is similar to that reported for tamoxifen, the most common adverse effects being hot flushes, sweating, nausea and/or vomiting, dizziness, oedema, and vaginal discharge and/or bleeding. Thus, toremifene provides an equally effective and well tolerated alternative to tamoxifen for the first-line endocrine therapy of postmenopausal advanced breast cancer. Preclinical studies showing toremifene to have a lower carcinogenic potential than tamoxifen indicate that toremifene may be a preferable agent for long term treatment regimens; however, these findings require confirmation in the clinical setting.

The efficacy and safety of TAT-59 (miproxifene phospate) were compared with tamoxifen citrate (TAM) in ER-positive or ER-unknown patients with advanced or recurrent breast cancer, using the double-blind method. TAT-59 and TAM were both given 20 mg/body orally for over 12 weeks in daily doses. Eligible cases were 93 in the TAT-59 group and 102 patients in the TAM group. The response rate was shown to be 30.1% (28/93) in the TAT-59 group and 26.5% (27/102) in the TAM group. Statistical equivalence between both treatments was proven at 90% confidence interval (-8.5% < or =, < or = 12.8%). Adverse reactions observed in the patients receiving TAT-59 were hot flush, nausea and vomiting, sweating, anorexia, abnormal values in liver function tests, and anemia, showing no differences from the TAM group. Leukopenia (4.9%) and thrombopenia (2.9%) reactions were found only in the TAM group. Two patients in the TAT-59 group and three in the TAM group discontinued treatment due to adverse reactions. However, these adverse reactions were reversible in both groups. In conclusion, TAT-59 was showed comparable efficacy and safety with TAM in ER-positive or ER-unknown patients with advanced or recurrent breast cancer.

Acupuncture has become a popular complementary treatment in oncology, particularly as patients seek non-pharmacological alternatives to provide symptom control. A considerable body of evidence suggests that acupuncture modulates neurological processes to bring about its effects. This basic research is supported by an increasing number of positive clinical studies of varying quality. Lower quality studies have hampered the widespread acceptability of acupuncture, with some deeming the inter-personal skills of the practitioner to be more powerful than the needle or its equivalent. More recent randomised control trials (RCTs) have sought to settle this controversy, with mixed results. The literature was searched to identify, where possible, RCTs involving acupuncture and various common cancer symptoms. A potential role for acupuncture was found in the following cancer symptoms: pain, nausea and vomiting, xerostomia, hot flushes, fatigue, anxiety, depression and insomnia. Acupuncture is safe with minimal side-effects, and is clinically effective for the management of these symptoms. Continuing research using validated methodology is essential. In the interim, health professionals should be open to explore the use of acupuncture with their cancer patients.

Oncology acupuncture has become a new and promising field of research because more and more cancer patients have sought non-pharmacological alternatives for symptom management. While different mechanisms have been proposed to explain its efficacy, including theories of the neural system, endocrine cytokine or immunological regulation, its eventual role has become that of alleviating the side effects induced by chemotherapy or radiotherapy. In this paper, we have reviewed the related articles focusing on acupuncture mechanisms and applications in cancer care to provide a quick sketch of acupuncture in cancer care. A detailed search was performed to identify the randomized controlled trials (RCTs) and systematic reviews on acupuncture in oncology, using PUBMED and Cochrane. The search terms included: Acupuncture, acupressure, and cancer. Additional terms were used to target specific symptoms (i.e., breast cancer, hot flash, xerostomia, nausea, vomiting, cancer pain, insomnia, fatigue). Two authors independently extracted data for analysis and review. Ultimately, 25 articles underwent full-text review. Recent trials made efforts in studying (a) hot flashes in breast cancer, (b) xerostomia induced by radiotherapy in head and neck cancer, (c) nausea and vomiting post-chemotherapy, (d) cancer pain, and (e) fatigue and insomnia in cancer patients. Controversial results for acupuncture application in cancer care appeared in different categories, but a trend emerged that acupuncture can palliate cancer-related symptoms. The research to date certainly offers us a valid complementary therapy in treating cancer-related symptoms. Meanwhile, practical strategies with safe measures for enhancing the efficacy are needed in further interventions, as well as continuing research with a validated methodology.

At least 25-30% of patients with cancer and an even higher percentage of patients in an advanced phase of illness meet the criteria for a psychiatric diagnosis, including depression, anxiety, stress-related syndromes, adjustment disorders, sleep disorders and delirium. A number of studies have accumulated over the last 35 years on the use of psychotropic drugs as a pillar in the treatment of psychiatric disorders. Major advances in psycho-oncology research have also shown the efficacy of psychotropic drugs as adjuvant treatment of cancer-related symptoms, such as pain, hot flushes, pruritus, nausea and vomiting, fatigue, and cognitive impairment. The knowledge about pharmacokinetics and pharmacodynamics, clinical use, safety, side effects and efficacy of psychotropic drugs in cancer care is essential for an integrated and multidimensional approach to patients treated in different settings, including community-based centres, oncology, and palliative care. A search of the major databases (MEDLINE, Embase, PsycLIT, PsycINFO, the Cochrane Library) was conducted in order to summarize relevant data concerning the efficacy and safety of pharmacotherapy for cancer-related psychiatric disorders in cancer patients across the trajectory of the disease.
