The effectiveness for early abortion of a single dose (75 mg intramuscularly) of methotrexate, followed 5-6 days later by 800 mcg of misoprostol vaginally, was investigated in 99 women presenting to a Pittsburgh, Pennsylvania (US), hospital with pregnancies under 50 days' gestation. Complete abortion occurred in 94 patients (94.9%). There were no significant differences in this rate by gestation (up to 42 days vs. 43-49 days). In 70 cases (70.7%), abortion occurred in the 24 hours following the initial or repeat misoprostol dose. Overall, 77.8%, 86.9%, and 91.9% of women had expelled the fetus by 14, 28, and 35 days, respectively, after receiving methotrexate. Vaginal bleeding lasted an average of 17 days in women who aborted in 24 hours and 11 days in those with delayed abortion. Side effects associated with methotrexate included nausea (47%), warmth/hot flashes (43%), diarrhea (22%), dizziness (21%), headache (16%), and vomiting (12%). These results are comparable to those obtained with an intramuscular dose of 50 mg/sq. m or an oral dose of 50 mg of methotrexate. The lowest effective dose of methotrexate, when combined with misoprostol for abortion, remains to be determined.

Patients with hormone-sensitive breast cancer who have responded to tamoxifen may receive additional benefit from a second endocrine agent following progression or relapse after tamoxifen therapy. Fulvestrant (Faslodex((R)), ICI 182780, AstraZeneca Pharmaceuticals; Wilmington, Delaware) is a selective antagonist of estrogen designed to have no estrogenic effects. Lack of aqueous solubility led to the development of a parenteral formulation for monthly intramuscular administration. Fulvestrant has been shown to inhibit the proliferative effects of estrogen on sensitive tissues in vitro and in vivo, and is without apparent measurable estrogenic activity. The data upon which marketing approval for fulvestrant was based are summarized below. Eight hundred fifty-one postmenopausal women with advanced breast cancer were enrolled in two phase III studies, 400 in a North American double-blind study and 451 in a European open-label study, comparing the efficacy and safety of fulvestrant with anastrozole. Four hundred twenty-eight patients were randomized to receive fulvestrant 250 mg monthly by intramuscular injection and 423 patients were to receive anastrozole 1 mg daily. Patients were considered hormone sensitive either by receptor status or previous response to endocrine therapy. Over 96% of patients had previously received tamoxifen, either in the adjuvant setting or as treatment for metastatic disease. The primary study end points were response rate and time to progression. Response rates for patients treated with fulvestrant were 17% and 20% in the North American and European trials, respectively, compared with 17% and 15% in the anastrozole treatment arms. There were no statistically significant differences in response rates, time to progression, or survival between treatment arms in either study. The most common adverse events attributed to the treatment (>10%) were injection-site reactions and hot flashes. Common events (1%-10%) included asthenia, headache, and gastrointestinal disturbances (nausea, vomiting, and diarrhea), as well as rash and urinary tract infections. A small increase in joint disorders was reported in the anastrozole-treated patients. On April 25, 2002, fulvestrant 250 mg by monthly intramuscular injection was approved by the U.S. Food and Drug Administration for the treatment of hormone receptor-positive metastatic breast cancer in postmenopausal women with disease progression following antiestrogen therapy. Approval was based on similarity of response rates and time to progression between fulvestrant and anastrozole.

Due to the long-term health risks now associated with hormone replacement therapy, many menopausal women are actively seeking alternative treatments. One such alternative is black cohosh (Actaea racemosa, syn. Cimicifuga racemosa), which has been used in the United States for the treatment of gynecologic complaints for more than 100 years. Review of the published clinical data suggests that black cohosh may be useful for the treatment of menopausal symptoms, such as hot flashes, profuse sweating, insomnia, and anxiety. Results from the most recently published trial, however, indicate that black cohosh is not effective for the treatment of menopausal symptoms in breast cancer survivors being treated with tamoxifen. Because the overall quality of the published clinical trials is low, two new randomized, double-blind, placebo-controlled clinical trials are currently underway in the United States. To date, only one standardized black cohosh extract has been tested clinically; the current recommended dose is 40-80 mg per day. At least 4-12 weeks of treatment may be required before any therapeutic benefits may be apparent. Adverse reactions such as nausea, vomiting, headaches, dizziness, mastalgia, and weight gain have been observed in clinical trials. No drug interactions are reported in the medical literature. The estrogenic effects of black cohosh are controversial, and the more recent data indicate that black cohosh extracts may have an anti-estrogenic activity. Owing to potential effects on sex hormones, however, black cohosh should not be administered to children or during pregnancy and lactation.

Symptom control has become increasingly recognized as an important goal in patient care. In this article, advances in symptom assessment, and various definitions of symptom improvement are reviewed. Theoretical concepts underlying symptom control and clinically significant change are presented, as well as the role of symptom control as an endpoint in clinical trials. Symptom control is then surveyed in two broad categories for selected symptoms. The first area is therapy related symptoms, secondary to chemotherapy, radiation, hormonal therapy, and surgery. Symptoms reviewed include chemotherapy related mucositis, emesis, fatigue; hot flashes; and radiation related dermatitis, xerostomia, and mucositis. The second area is palliative oncologic approaches to disease-related symptoms. Results in palliative chemotherapy, palliative radiation therapy, cancer pain, and lack of appetite are summarized. Areas requiring further research are noted. Findings are presented in both a clinical and research context to help guide the reader with interpreting symptom control studies.

Since the publication of the results of the Women's Health Initiative that described the risks of hormone replacement therapy, many women are actively seeking alternative treatments for menopausal symptoms. Black cohosh (Actaea racemosa, syn. Cimicifuga racemosa) is one such alternative that has been used in the US for over 100 years. To date only two cimicifuga extracts have been tested clinically, and the current recommended dosage is 40-80 mg/day. Review of the published clinical data suggests that cimicifuga may be useful for the treatment of menopausal symptoms, such as hot flashes, profuse sweating, insomnia, and anxiety. However, the methodology used in most of the trials is poor and further clinical assessment of cimicifuga is needed. In terms of safety, transient adverse events such as nausea, vomiting, headaches, dizziness, mastalgia, and weight gain have been observed in clinical trials. A few cases of hepatotoxicity have been reported, but a direct association with the ingestion of cimicifuga has not been demonstrated. The most recent data suggest that cimicifuga is not estrogenic.

In recent studies, patients have reported an increased use of complementary and alternative medicine (CAM). Acupuncture is a popular complementary therapy for patients with cancer. This article will provide current cancer treatment providers with information on acupuncture as well as the research conducted on cancer symptoms and side effects of cancer treatments. Antiemetic studies are the most prevalent and contain the most promising results. Several studies have found that acupuncture significantly reduces the number of emesis (vomiting) episodes for patients receiving chemotherapy. While studies on pain control vary due to the heterogeneity of pain, there are few studies investigating pain caused from cancer and the removal of cancerous tumors. These studies, while promising, provide basic results that need further investigation for more definitive results. Although relatively few studies have been done on anxiety and depression, several researchers have found acupuncture to be just as effective as or more effective than antidepressants for patients without cancer. Studies on breathlessness, while small, have shown acupuncture to have a significant positive effect on chronic obstructive pulmonary disease, breathlessness associated with end-stage cancer, and asthma. Researchers studying xerostomic individuals who have received salivary gland irradiation found significant positive results in salivary flow rates compared to baseline. Patients with hot flashes due to hormonal imbalance may benefit from the use of acupuncture. A recent pilot study showed improvement of chronic postchemotherapy fatigue following acupuncture treatments. Many individuals with cancer have turned to acupuncture because their symptoms persisted with conventional treatments or as an alternative or complement to their ongoing treatments. Despite the immense popularity in the community, few large randomized trials have been conducted to determine the effects acupuncture has on cancer symptoms and side effects of treatments. A majority of the current studies have shown beneficial effects that warrant further investigation with large trial sizes.

We present a unique case of a neuroendocrine syndrome in a patient with Stage IV vaginal melanoma metastatic to the liver that was successfully palliated with octreotide. Similar to the carcinoid syndrome, the patient exhibited chronic diaphoresis, intermittent low-grade fevers, dizziness, nausea with vomiting, and hot flashes. The symptoms on admission of acute hypotension, acute exacerbation of abdominal pains, and intractable nausea with vomiting suggested a neuroendocrine crisis secondary to massive degranulation and hormone release. Consistent with our hypothesis, her plasma chromogranin A was found to be elevated. Octreotide was used successfully to palliate her symptoms. When the octreotide was stopped, all her symptoms returned. As the use of octreotide is gaining application in palliative care, this case highlights the effectiveness of its use in a select group of patients whose symptoms would be otherwise difficult to manage.

Breast cancer treatment currently requires the joint efforts of a multidisciplinary team to effectively combine chemotherapy, hormone therapy, biological agents, surgery and radiation therapy when needed. To develop such a treatment plan, it is important to know the benefits as well as the potential toxic effects of each therapy. Thus, many patients with early breast cancer complain of collateral adverse events such as fatigue, nausea, vomiting, loss of libido, hot flashes, night sweats or neuropathy due to the complex therapies they are receiving. To date, the treatment of such symptoms is an important issue that greatly affects the quality of life of these patients. In this review, we report the content of a multi-expert meeting where the incidence of and medical approach to some of the most common adverse events encountered during the treatment of patients with early breast cancer were analysed.

Acupuncture is often recommended for obstetrical and gynecological conditions but the evidence is confusing. We aim to summarize all recent systematic reviews in this area. Western and Asian electronic databases were searched for systematic reviews of any type of acupuncture for any type of gynecological conditions. Our own files were hand-searched. Systematic reviews of any type of acupuncture for any type of gynecological conditions were included. Non-systematic reviews and systematic reviews published before 2004 were excluded. No language restrictions were applied. Data were extracted according to predefined criteria and analysed narratively. Twenty-four systematic reviews were included. They relate to a wide range of gynecological conditions: hot flashes, conception, dysmenorrhea, premenstrual syndrome, nausea/vomiting, breech presentation, back pain during pregnancy, and procedural pain. Nine systematic reviews arrived with clearly positive conclusions; however, there were many contradictions and caveats. The evidence for acupuncture as a treatment of obstetrical and gynecological conditions remains limited.

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.
