American Cancer Society guidelines for breast screening with MRI as an adjunct to mammography.

New evidence on breast Magnetic Resonance Imaging (MRI) screening has become available since the American Cancer Society (ACS) last issued guidelines for the early detection of breast cancer in 2003. A guideline panel has reviewed this evidence and developed new recommendations for women at different defined levels of risk. Screening MRI is recommended for women with an approximately 20–25% or greater lifetime risk of breast cancer, including women with a strong family history of breast or ovarian cancer and women who were treated for Hodgkin disease. There are several risk subgroups for which the available data are insufficient to recommend for or against screening, including women with a personal history of breast cancer, carcinoma in situ, atypical hyperplasia, and extremely dense breasts on mammography. Diagnostic uses of MRI were not considered to be within the scope of this review.

The Role of Adjuvant Chemotherapy Following Cystectomy for Invasive Bladder Cancer: A Prospective Comparative Trial

We assigned 91 patients with deeply invasive, pathological stage P3, P4 or N+ and Mo transitional cell carcinoma of the bladder (with or without squamous or glandular differentiation) to adjuvant chemotherapy or to observation after radical cystectomy and pelvic lymph node dissection. For most patients chemotherapy was planned as 4 courses at 28-day intervals of 100 mg./M.2 cisplatin, 60 mg./M.2 doxorubicin and 600 mg./M.2 cyclophosphamide. A significant delay was shown in the time to progression (p = 0.0010) with 70% of the patients assigned to chemotherapy free of disease at 3 years compared to 46% in the observation group. Median survival time for patients in the chemotherapy group was 4.3 years compared to 2.4 years in the observation group (p = 0.0062). In addition to treatment groups, important prognostic factors included age, gender and lymph node status. The number of involved lymph nodes was the single most important variable. We recommend adjuvant chemotherapy for patients with invasive transitional cell carcinoma after definitive surgical resection.

Minority cancer patients and their providers : Pain management attitudes and practice

The goals of the current studies were: 1) to determine the pain treatment needs of socioeconomically disadvantaged African‐American and Hispanic patients with recurrent or metastatic cancer and 2) to assess the attitudes of health care professionals who treat them.

Depression, Correlates of Depression, and Receipt of Depression Care Among Low-Income Women With Breast or Gynecologic Cancer

PURPOSE To assess the prevalence of depression among low-income, ethnic minority women with breast or gynecologic cancer, receipt of antidepressant medications or counseling services, and correlates of depression. PATIENTS AND METHODS Study patients were 472 women receiving cancer care in an urban public medical center. Women had a primary diagnosis of breast (stage 0 to III) or gynecologic cancer (International Federation of Gynecology and Obstetrics stage 0 to IIIB). A diagnostic depression screen and baseline questionnaire were administered before or during active treatment or during active follow-up. Self-report data were collected on receipt of depression treatment, use of supportive counseling, pain and receipt of pain medication, functional status and well-being, and perceived barriers to cancer care. RESULTS Twenty-four percent of women reported moderate to severe levels of depressive disorder (30% of breast cancer patients and 17% of gynecologic cancer patients). Only 12% of women meeting criteria for major depression reported currently receiving medications for depression, and only 5% of women reported seeing a counselor or participating in a cancer support group. Neither cancer stage nor treatment status was correlated with depression. Primary diagnosis of breast cancer, younger age, greater functional impairment, poorer social and family well-being, anxiety, comorbid arthritis, and fears about treatment side effects were correlated with depression. CONCLUSION Findings indicate that depressive disorder among ethnic minority, low-income women with breast or gynecologic cancer is prevalent and is correlated with pain, anxiety, and health-related quality of life. Because these women are unlikely to receive depression treatment or supportive counseling, there is a need for routine screening, evaluation, and treatment in this population.

Cisplatin, methotrexate and bleomycin for the treatment of carcinoma of the penis: a Southwest Oncology Group study.

PURPOSE We ascertained whether combined cisplatin, methotrexate and bleomycin have efficacy for treating locally advanced or metastatic carcinoma of the penis, and evaluate the toxicity resulting from this regimen. MATERIALS AND METHODS Patients had biopsy proved locally advanced or metastatic epidermoid carcinoma of the penis. Chemotherapy consisted of 75 mg./m.2 cisplatin infused intravenously on day 1, 25 mg./m.2 intravenous bolus of methotrexate on days 1 and 8, and 10 unit per m.2 intravenous bolus of bleomycin on days 1 and 8 with a cycle length of 21 days. Our study was performed as a standard phase II evaluation with 2 stages of accrual. RESULTS Enrolled in this study were 45 patients, including 40 who were evaluable for a response. There were 5 complete and 8 partial responses for a 32.5% response rate. Five treatment related deaths occurred and 6 of the 36 remaining patients evaluable for toxicity had 1 or more life threatening toxic episodes. CONCLUSIONS A regimen of cisplatin, methotrexate and bleomycin appears to have promising results. However, toxicity was prodigious, and an emphasis of future research should be to decrease toxicity.

Long-Term Administration of Mifepristone (RU486): Clinical Tolerance During Extended Treatment of Meningioma

Background: Mifepristone (RU486) is an oral antiprogestational and, to a lesser extent, antiglucocorticoid agent commonly used for short-term (single-day) therapy. However, treatment of neoplasms or chronic conditions will require long-term administration. Meningioma is a benign central nervous system tumor that is often progesterone-but not estrogen-receptor positive, making long-term antiprogestational therapy a logical treatment strategy. Methods: Patients with unresectable meningioma were treated with oral mifepristone 200 mg/day. This dose was selected to provide significant antiprogestational but not antiglucocorticoid activity. Patients also received oral dexamethasone 1 mg/day for the first 14 days. Serial follow-up allowed evaluation for tolerability and side effects of long-term therapy as well as observation for efficacy (tumor shrinkage or improvement in visual fields). Results: Twenty-eight patients received daily oral mifepristone for a total of 1,626 patient-months of treatment. The median duration of therapy was 35 months (range 2–157 months). Repeated oral administration was well tolerated with mild fatigue (22 patients), hot flashes (13 patients), and gynecomastia/breast tenderness (6 patients) being the most common side effects. However, endometrial hyperplasia or polyps were documented in 3 patients and one patient developed peritoneal adenocarcinoma after 9 years of therapy. Minor responses (improved automated visual field examination or improved CT or MRI scan) were noted in 8 patients, 7 of whom were male or premenopausal female. Conclusions: Long-term administration of mifepristone is feasible and clinically well tolerated, with generally mild toxicity. However, endometrial hyperplasia was noted in several patients. In view of the association between long-term treatment with tamoxifen (another agent that can induce an unopposed estrogen effect) and endometrial cancer, this observation will require further investigation and screening. Minor regression of meningioma that can result in significant clinical benefit is suggested in the male and premenopausal female subgroups of patients.

Neoadjuvant therapy for breast cancer

The past few decades have seen an increase in both the role and the complexity of neoadjuvant therapy for breast cancer. Neoadjuvant therapy was initially described as systemic chemotherapy for inflammatory or locally advanced breast cancer but now entails a combination of chemotherapy, endocrine therapy, and targeted therapy. Neoadjuvant systemic therapy is employed for inoperable inflammatory and locally advanced breast cancer, and also for patients with operable breast cancers who desire breast‐conserving therapy (BCT) but are not candidates based on the initial size of the tumor in relation to the size of the breast. Neoadjuvant therapy in this subset of patients may impact the surgical options. This review will summarize the benefits of neoadjuvant systemic therapy and implications for BCT, the timing of sentinel node biopsy, and the utility of magnetic resonance imaging (MRI) to predict response to therapy.

Dose ranging phase I study of the serotonin antagonist GR38032F for prevention of cisplatin-induced nausea and vomiting.

GR38032F is a specific 5-HT3 (serotonin) receptor antagonist with antiemetic activity in animal and early human studies. We performed a dose-ranging phase I study of GR38032F in 43 evaluable patients receiving cisplatin 60 120 mg/m2 for the first time (38 of these patients were chemotherapy-naive). Intravenous GR38032F was administered over a dose range from 0.01 to 0.48 mg/kg given three times at four-hour intervals beginning one half hour before cisplatin, and patients were observed for 24 hours. An additional five patients were treated with 0.18 mg/kg given three times at six-hour intervals. Excellent antiemetic efficacy was noted, with 44% of patients experiencing no vomiting and 26% no nausea. Major protection from vomiting (less than or equal to 2 episodes) and from nausea (less than or equal to 2 hours) was experienced by 81% and 44%, respectively. Mild to moderate headache (40%), lightheadedness (21%), and elevated transaminase (19%) were the most common adverse events reported. One patient experienced an apparent hypersensitivity reaction that responded to conventional medications. No extrapyramidal reactions or akathisia were seen. GR38032F was effective through most of the dose range. However, efficacy decreased at the 0.01 mg/kg level and number and intensity of adverse events increased at the 0.48 mg/kg level. Analysis of those patients receiving high-dose cisplatin (100 to 120 mg/m2) revealed a positive association of GR38032F dose and antiemetic activity (Fishers exact test, two-sided; P less than .05). The 5-HT3 receptor antagonists may provide antiemetic efficacy similar to high-dose metoclopramide without antidopaminergic toxicity. The maximum recommended dose on this schedule of GR38032F is 0.36 mg/kg.

Cancer Treatment Adherence among Low-Income Women with Breast or Gynecologic Cancer: A Randomized Controlled Trial of Patient Navigation

The authors implemented a controlled, randomized trial that compared 2 interventions: the provision of written resource navigation information (enhanced usual care [EUC]) versus written information plus patient navigation (TPN) aimed at improving adjuvant treatment adherence and follow‐up among 487 low‐income, predominantly Hispanic women with breast cancer or gynecologic cancer.

Surgical resection in patients withnonseminomatous germ cell tumor who fail to normalize serum tumor markers after chemotherapy

OBJECTIVE Patients with high-stage nonseminomatous germ cell tumors treated with platinum-based chemotherapy who have residual radiographic evidence of disease and fail to normalize tumor markers present a difficult clinical dilemma. Some authors feel that these patients are not appropriate surgical candidates. Our practice has been to offer certain patients salvage surgery in an attempt for cure. This report is designed to review that experience and critically analyze the results. METHOD We report a series of 16 such patients with advanced-stage nonseminomatous germ cell tumors who had persistently elevated alpha fetoprotein and/or human chorionic gonadotropin. All underwent resection of all radiographically evident sites of residual disease following induction or salvage chemotherapy. RESULTS Ten patients had only retroperitoneal (RP) metastasis. Six patients had more than one site of residual disease--4 RP and lung, 2 RP and liver. There were no postoperative deaths. The mean postoperative stay was eleven days (range 7 to 36 days). Six patients (37%) are alive and free of disease at a mean of seventy-four months following surgery (range 20 to 145 months). Five had RP disease only. Ten patients died of disease at a mean of eight months postoperatively (range 5 to 21 months). CONCLUSIONS Patients with advanced nonseminomatous germ cell tumor who fail to normalize their serum tumor markers after adequate platinum-based chemotherapy should be considered for surgical resection of all radiographically evident residual disease. In select cases this practice offers the only viable chance for cure.
