Diagnosis and management of spinal cord sarcoidosis.

BACKGROUND: Sarcoidosis of the spinal cord is very rare, affecting less than 1% of patients with sarcoidosis. METHODS: We retrospectively reviewed the charts of all patients with biopsy proven sarcoidosis and spinal cord involvement seen in our Interstitial Lung Disease and Sarcoidosis Clinic at the University of Cincinnati over a nineteen year period. Presentation of disease, method of diagnosis, and response to immunosuppressive therapy (methotrexate, azathioprine, or cyclophosphamide) were noted. RESULTS: Seventeen patients with spinal cord sarcoidosis were identified. All patients presented with insidious parethesias or weakness. Diagnosis was confirmed by biopsy of spinal cord lesions in two patients, dural biopsy in three patients, mediastinoscopy in eight patients, bronchoscopy in two patients, skin biopsy in one patient, and liver biopsy in one patient. Only four patients were diagnosed with sarcoidosis prior to spinal cord involvement. Cytotoxic therapy was initiated to reduce the daily dose of prednisone to less than 10 mg. Fourteen patients were evaluated at least six months after starting cytotoxic therapy. Of these evaluable patients, ten patients received methotrexate plus low dose prednisone and five responded. One patient received azathioprine plus low dose prednisone and responded. One patient received azathioprine, methotrexate, and low dose prednisone and responded. All seven patients that received cyclophosphamide responded. CONCLUSIONS: Spinal cord sarcoidosis should be considered in any patient presenting with gradual onset of paresthesias or weakness regardless of the diagnosis of sarcoidosis. Prompt treatment is important in long term outcome. Cyclophosphamide was an effective, well tolerated corticosteroid-sparing agent for patients with spinal cord sarcoidosis.

Impact of metastatic estrogen receptor and progesterone receptor status on survival.

Hormone responsive breast cancer is usually determined by the presence of estrogen receptors (ER) or progesterone receptors (PR) on primary invasive breast cancers. Adjuvant and metastatic hormone therapy are recommended based on primary ER and PR determination. Little information is available to determine if primary hormone receptors correlate with metastatic disease and if survival is influenced by metastatic receptor status. We retrospectively compared primary to metastatic tumor ER and PR content from 200 metastatic breast cancer patients. ER and PR analyses were available in both primary and metastatic disease in 200 and 173 patients, respectively. There was a correlation between both the ER and PR in the primary and metastatic lesion (p < 0.001). However, in 60 of 200 (30%) patients, discordance between primary and metastatic ER was noted. Tumors from 68 of 173 (39.3%) showed discordance for PR. In 39 (19.5%) patients, the ER primary status was positive and metastatic status was negative and in 21 (10.5%) patients, the primary status was negative and metastatic status was positive. Survival from the time of metastatic diagnosis was calculated. Those patients with ER positive primary and metastatic tumors (Positive/Positive) or only the metastatic lesion (Negative/Positive) had similar median survival (1131 and 1111 days, respectively). However, patients with tumors that changed from positive primary to negative metastasis (Positive/Negative) experienced significantly shorter median survival (669 days, p < 0.05). Likewise, median survival (580 days) was significantly shorter for patients with primary and metastasis ER negative (Negative/Negative, p < 0.001) compared to Positive/Positive (p < 0.001) or compared to Negative/Positive (p < 0.02). The changes in PR status were not associated with a change in survival. We found a significant discordance between hormone receptor content of primary versus metastatic breast cancer. The ER status of the metastatic lesion was a better predictor of survival. Therefore, optimal metastatic treatment cannot be determined solely on primary ER and PR analysis.

Etanercept for refractory ocular sarcoidosis: results of a double-blind randomized trial.

PURPOSES: Study a tumor necrosis factor receptor antagonist (etanercept) in the treatment of chronic ocular sarcoidosis. SUBJECTS AND METHODS: Eighteen patients with ocular sarcoidosis and ongoing inflammation in the eyes. All patients had received at least 6 months of therapy with methotrexate and were currently receiving corticosteroids. Patients were randomized to receive either etanercept, 25 mg subcutaneously twice a week, or placebo in a double-blind randomized trial. Treatment for ocular inflammation with systemic and local corticosteroids at the beginning and end of 6 months of treatment was noted. All patients underwent an ocular examination at the beginning and the end of the study by one ophthalmologist who was unaware of what treatment the patient was receiving. RESULTS: Three of the patients treated with etanercept and one treated with placebo were being treated with lower doses of corticosteroids by the end of the study. However, three of the etanercept patients and one of the placebo patients required larger doses of corticosteroids by the end of the study. The ophthalmology global assessment improved for two of the etanercept-treated patients and three of the placebo-treated patients. CONCLUSION: For most patients, therapy with etanercept was not associated with a significant improvement in their chronic ocular disease.

Capecitabine plus paclitaxel as front-line combination therapy for metastatic breast cancer: a multicenter phase II study.

PURPOSE: The goal of this multicenter, open-label phase II study was the clinical evaluation of combination therapy with the oral fluoropyrimidine capecitabine and the taxane paclitaxel in patients with metastatic breast cancer (MBC). PATIENTS AND METHODS: Forty-seven patients with MBC received oral capecitabine at 1650 mg/m(2)/d (825 mg/m(2) twice daily) on days 1 through 14, and intravenous infusion of paclitaxel at 175 mg/m(2) on day 1 of each 21-day treatment cycle. Treatment continued until disease progression, intolerable toxicity, or patient' s decision to discontinue. Patients (35 to 76 years old) had a median Karnofsky performance status of 90%. Forty-four patients (94%) received study treatment as first-line therapy for metastatic disease. RESULTS: Objective responses occurred in 24 (51%) patients; seven (15%) complete responses and 17 (36%) partial responses. Stable disease lasting 180 days or more was observed in nine (19%); the clinical response rate was 70%. Median duration of response was 12.6 months, median time to disease progression was 10.6 months, and median overall survival time was 29.9 months. The most common treatment-related adverse events, regardless of severity, were alopecia, hand-foot syndrome, nausea, and fatigue. Neutropenia (15%), alopecia (13%), and hand-foot syndrome (11%) were the only grade 3 or 4 treatment-related adverse events that occurred in more than 10% of patients. CONCLUSION: The combination of capecitabine plus paclitaxel is a highly active and generally well-tolerated regimen for first-line treatment of MBC.

Leflunomide for chronic sarcoidosis.

BACKGROUND AND AIM: Leflunomide (Arava) is a cytotoxic drug which has been used as a single agent or in combination with methotrexate for the treatment of rheumatoid arthritis. It appears to have less toxicity than methotrexate. The use of leflunomide for sarcoidosis patients has not been systematically evaluated. METHODS: The records were reviewed from all patients treated at a tertiary sarcoidosis center from July 2002-July 2003, and information from patients treated with either leflunomide or methotrexate was analyzed for efficacy and toxicity. RESULTS: Thirty-two patients were treated with leflunomide; fifteen patients received concurrent therapy with methotrexate. The most common indications for therapy were ocular and lung disease. Complete or partial response to leflunomide was seen in 12 of 17 treated with leflunomide alone, and 13 of 15 treated with leflunomide plus methotrexate. There was no difference in the response rate for eye [23/28 (82%)] versus pulmonary disease [12/16 (75%)]. Seventeen patients were treated with leflunomide alone because of methotrexate toxicity (nausea in 12 and pulmonary symptoms in five). All but two tolerated leflunomide. Three patients experienced nausea leading to drug discontinuation, but no other serious adverse reaction was encountered with leflunomide. CONCLUSION: Leflunomide was well tolerated in patients with chronic sarcoidosis. It appears to be as effective as methotrexate, with less toxicity. It should be considered as an alternative in chronic sarcoidosis patients who cannot tolerate methotrexate.

Newer therapies for cutaneous sarcoidosis: the role of thalidomide and other agents.

Skin involvement occurs in a third of patients with sarcoidosis. The type of lesions can range from the transient erythema nodosum to the chronic facial lesion lupus pernio. For some patients with sarcoidosis, lesions on the face or elsewhere on the body may be the major or only indication for therapy. These lesions are often chronic and the use of corticosteroids may lead to more long-term complications. Conventional alternatives to corticosteroids include antimalarial agents, methotrexate, and azathioprine. Recently, several drugs have been studied for chronic cutaneous sarcoidosis; thalidomide has been the most widely used. Thalidomide has been demonstrated to suppress tumor necrosis factor (TNF) release, which may be important at both the initial and chronic phases of the inflammation of sarcoidosis and appears to be crucial as part of the initial granulomatous response. Thalidomide has a different toxicity profile than corticosteroids or immunosuppressives. The usual dosage has recently been investigated in a dose-escalation trial, with the majority of patients responding to 100 mg/day. Drug toxicity has been reported in the sarcoidosis trials. The most serious adverse effect has been peripheral neuropathy, which often resolves by reducing the dose or discontinuing the medication. Other drugs that have been studied for sarcoidosis include infliximab and tetracyclines. Infliximab is a chimeric monoclonal antibody against TNF, and several published reports have shown it to be effective for the treatment of cutaneous sarcoidosis. The efficacy of tetracyclines for cutaneous sarcoidosis could be on the basis of their immunologic properties. In addition, these drugs have potent antimicrobial activity against Propionibacterium acnes; there is increasing evidence to suggest this may be one of the causes of sarcoidosis. However, most of the newer agents for cutaneous sarcoidosis have only been studied in small series. Over the next few years, it is hoped that there will be clinical trials to determine the role of each new therapy in the treatment of cutaneous sarcoidosis.

Sarcoidosis.

There have been several new insights into the cause and treatment of sarcoidosis. Studies of genetic variation have shown that specific genetic polymorphisms are associated with increased risk of disease or affect disease presentation. These polymorphisms include variation of MHC and cytokines such as tumour necrosis factor (TNF). Not all investigators have come to the same conclusion, suggesting an interaction of various factors, including the patient's ethnic origin. Treatment of sarcoidosis varies considerably. Patients with symptomatic disease for more than 2-5 years have been of particular interest. Corticosteroids remain the standard of care in such cases, but immunosuppressive drugs have proved steroid-sparing in many patients. New agents, including pentoxifylline, thalidomide, and infliximab have proved useful in selected cases. The effectiveness of these agents seems to lie in their ability to block TNF, especially in the treatment of chronic disease.

Role of liver function tests in detecting methotrexate-induced liver damage in sarcoidosis.

BACKGROUND: Methotrexate has become a standard second-line agent for the treatment of sarcoidosis. Because sarcoidosis has a high frequency of liver involvement, we routinely perform a liver biopsy after each cumulative gram of methotrexate therapy in patients with sarcoidosis in whom we plan to continue therapy. METHODS: Following a previously described protocol for methotrexate therapy, we have performed 100 liver biopsies on 68 patients with chronic sarcoidosis at our institution. On the basis of the liver biopsy results, we identified the following 4 groups: sarcoidosis (47 cases), toxic effects of methotrexate (14 cases), hepatitis C (2 cases), and normal liver tissue (37 cases). RESULTS: We found no difference among the groups in terms of age, weight at time of biopsy, the number of patients receiving corticosteroids at the time of biopsy, cumulative dose of methotrexate, race, or sex. The 14 cases of toxic reactions to methotrexate included 5 patients who had undergone 1 or more previous liver biopsies in which the results did not show toxic effects. We found a significant difference between groups for levels of alkaline phosphatase and asparate aminotransferase at the time of starting (or restarting) methotrexate therapy (analysis of variance, P<.05). This finding was also true for the liver function tests performed at the time of the biopsy (analysis of variance, P<.05). The highest values were for those whose biopsy findings showed sarcoidosis. CONCLUSIONS: Toxic reactions to methotrexate eventually occurred in more than 10% of patients with sarcoidosis treated for more than 2 years with methotrexate. Because of hepatic involvement owing to sarcoidosis, results of serial liver function tests were not useful in determining which patients would have this reaction to methotrexate.

Increased rate of brain metastasis with trastuzumab therapy not associated with impaired survival.

Trastuzumab is important for treatment of metastatic breast cancer patients with tumors that overexpress HER2/neu, but its penetration to the brain is poor. The aims of this study are to determine the prevalence of bone and brain metastasis during therapy, to compare the survival of breast cancer patients with brain metastasis who received trastuzumab to those patients not receiving trastuzumab, and to assess the impact of brain metastasis on the overall survival of trastuzumab patients. Of 103 patients treated with trastuzumab, 16 had brain metastasis and 43 had bone metastasis at the beginning of trastuzumab. The control group consisted of 196 patients with metastatic breast cancer who had never received trastuzumab. Six had brain metastasis and 75 had bone metastasis at the beginning of therapy. During therapy, only 9 of 60 trastuzumab patients (15%) developed bone metastasis, while 170 of 186 control patients (91%; c2 = 129.8, P < 0.0001) developed bone metastasis. In addition, 22 of 87 trastuzumab patients (25%) and 58 of 190 control patients (31%) subsequently developed brain metastasis. Control patients without brain metastasis experienced significantly better survival (median survival = 928 days) than those with brain metastasis (median survival = 639 days, c2 = 8.34, P < 0.005). There was no difference in survival for trastuzumab-treated patients if they acquired brain metastasis (median survival = 1400 days) or no brain metastasis (median survival > 2000 days, c2 = 0.12, P > 0.05). Patients receiving trastuzumab were unlikely to develop new bone metastasis but were as likely as control patients to develop brain metastasis. However, patients who developed brain metastasis experienced better survival compared with those patients with brain metastasis who never received trastuzumab.

Bilateral synchronous breast cancer and HER-2/neu overexpression.

Bilateral synchronous breast cancer appears to have a worse prognosis than comparable unilateral breast cancer. HER-2/neu expression in bilateral breast cancer has not been reported. The purpose of this study was to review the characteristics of patients with bilateral synchronous breast cancer and to report the incidence of HER-2/neu overexpression. Between 1984 and 1998, 58 patients were diagnosed with bilateral synchronous breast cancer (defined as both cancers diagnosed within 3 months). The paraffin blocks from both breast specimens were available and immunostained in 21 patients. Of 42 breast specimens, there were 31 invasive carcinomas and 11 noninvasive carcinomas. Of the 21 paired specimens immunostained for HER-2/neu, 11 were invasive cancers in both breasts, nine were invasive cancers in one breast and noninvasive cancers in the other breast, and one was noninvasive cancers in both breasts. Of the 31 invasive carcinomas, HER-2/neu was overexpressed (2-3+) in 22 (71%) and negative (0-1+) in nine (29%). In contrast, 35 of 101 (34.7%) consecutive unilateral invasive breast cancer specimens from our institution overexpressed HER-2/neu. The difference in HER-2/neu overexpression between patients with bilateral synchronous breast cancer and unilateral breast cancer (22/31 v.s. 35/101) was statistically significant (chi square = 11.3, p < 0.001). In cases where both breasts had invasive carcinoma, HER-2/neu overexpression could be either in one (six patients) or both breasts (four patients). The increased mortality of patients with bilateral synchronous breast cancer may be due to the higher incidence of HER-21neu overexpression.

Therapy for extrapulmonary sarcoidosis.

The treatment of extrapulmonary sarcoidosis has to be adapted to the various organs involved. No treatment is necessary for most asymptomatic individuals. In some cases, topical therapy is sufficient to control problems, especially skin and eye involvement. Systemic therapy usually starts with corticosteroids. However, for chronic forms of the disease, steroid sparing alternatives such as methotrexate and hydroxychloroquine are useful. In some neurologic and cardiac cases, the response to corticosteroids is limited. In that case, alternatives are sought for these refractory patients. Drugs that inhibit tumor necrosis factor may prove useful in these patients. Among the new anti-tumor necrosis factor drugs are thalidomide and infliximab, an antibody to tumor necrosis factor.

Raloxifene is associated with less side effects than tamoxifen in women with early breast cancer: a questionnaire study from one physician's practice.

OBJECTIVE: Selective estrogen receptor modulators (SERMs) are being used increasingly for the prevention and treatment of breast cancer. The currently available SERMs, tamoxifen and raloxifene, are both associated with antiestrogenic side effects that can be bothersome. However, no data exist on how they compare in this regard. We conducted a retrospective, questionnaire-based study to answer this question. METHODS: Women with early breast cancer in one physician's practice who had received either or both of these drugs were surveyed using a self-administered questionnaire. Respondents graded the frequency and severity of side effects related to estrogen deprivation, such as vaginal dryness, mood changes, hot flashes, weight gain, and changes in libido, as well as other side effects, such as vaginal discharge. They were separated into three groups for analysis (group 1, tamoxifen only; group 2, raloxifene only; group 3, both drugs). Side effects graded 4 or 5 (or weight gain >10 pounds) were considered severe. RESULTS: Two hundred sixty-four questionnaires were available for analysis. Women on raloxifene had a shorter average duration of therapy. In comparing the tamoxifen and raloxifene groups, vaginal discharge, severe hot flashes, and weight gain of >10 pounds were significantly more frequent with tamoxifen. However, weight gain was also related to the duration of therapy with either drug. CONCLUSIONS: In this observational study, antiestrogenic side effects were common with either tamoxifen or raloxifene. Raloxifene is associated with significantly less vaginal discharge and severe hot flashes than tamoxifen in women with early breast cancer. Although weight gain of >10 pounds may also occur less frequently on this drug, this may be confounded by the shorter average duration of raloxifene therapy.

CD44 associates with EGFR and erbB2 in metastasizing mammary carcinoma cells.

Type I receptor tyrosine kinases, including the epidermal growth factor receptor (EGFR) and erbB2, have been implicated in mammary carcinoma growth and metastasis. Recent evidence suggests that type I receptor signaling may be mediated by the CD44 family of transmembrane glycoproteins that also have been implicated in mammary tumor progression. Here, the authors tested whether CD44, EGFR, and erbB2 interacted and colocalized with one another in four mammary carcinoma cell lines (MCF-7, MDA-MB-231, MDA-MB-435, and MDA-MB-436) and in cytology samples obtained from patients with metastatic breast cancer. CD44 constitutively colocalized and coimmunoprecipitated with erbB2 and EGFR in all four mammary carcinoma cell lines. CD44 also colocalized with erbB2 and EGFR in all cytology samples expressing erbB2. CD44 colocalized with EGFR in cells from only 1 of 16 erbB2-negative cytology samples. These data indicate that CD44-EGFR-erbB2 protein complexes occur in a high proportion of metastatic mammary carcinomas and suggest that CD44-type I receptor colocalization may be a novel prognostic marker for aggressive mammary cancers.

Thalidomide for chronic sarcoidosis.

STUDY OBJECTIVES: Thalidomide therapy has been shown to modify granulomatous diseases, such as tuberculosis and leprosy. Lupus pernio is a skin manifestation of sarcoidosis that does not remit spontaneously, and was used as a marker of efficacy of thalidomide for sarcoidosis. DESIGN: An open-label, dose-escalation trial of thalidomide. SETTING: Patients were seen at one of four specialized sarcoidosis clinics in the United States. PATIENTS: Fifteen patients with lupus pernio and other manifestations of sarcoidosis unresponsive to prior therapy were enrolled. INTERVENTIONS: Skin lesions were assessed with visual examination by the treating physician, and photographic evaluation by a blinded panel of physicians reviewing photographs of the lesions before and after therapy. MEASUREMENTS AND RESULTS: Fourteen patients completed 4 months of therapy. All patients experienced some improvement in their skin lesions subjectively, and 10 of 12 evaluable patients showed improvement using photograph scoring. Five patients were better after 1 month (treated with 50 mg/d of thalidomide), seven more patients improved after 2 months (treated with 100 mg/d of thalidomide in the second month), and two patients required an additional month of 200 mg of thalidomide to achieve a response. Patients reported increased somnolence (n = 9), numbness (n = 7), dizziness (n = 2), constipation (n = 6), rash (n = 1), and increasing shortness of breath (n = 1). One patient discontinued therapy because of new-onset dyspnea, due to probably unrelated new-onset congestive heart failure. CONCLUSION: Thalidomide was an effective form of treatment for chronic cutaneous sarcoidosis. The drug was well tolerated and may be a useful alternative to systemic corticosteroids.

Use of fluticasone in acute symptomatic pulmonary sarcoidosis.

BACKGROUND: Inhaled corticosteroids have been used with variable success in sarcoidosis. The role of the inhaled corticosteroid fluticasone in symptomatic pulmonary patients was studied. METHODS: Twenty-two patients at five institutions who had been given an initial dose of oral corticosteroids within the prior four weeks were enrolled in a randomized double blind trial of inhaled fluticasone. An algorithm for the dosage of prednisone including rules for reducing dose was developed and applied at all centers. RESULTS: Of the 21 patients seen for more than one visit, 10 received fluticasone and 11 placebo. There was no significant difference in the improvement of vital capacity or average daily dose of prednisone for the fluticasone versus placebo. Eight of ten patients taking fluticasone had improvement in cough, while only 6 of 11 patients on placebo had improved cough despite taking oral corticosteroids (p = 0.36, N.S.). The algorithm for decreasing corticosteroid dosage was exactly applied in over 80% of patient visits and oral corticosteroids were used throughout most of the year of treatment. Patients registered higher complaints regarding increased appetite and polyuria when on ten mg or more prednisone a day. There was no clinical difference in the rate of toxicity for the fluticasone versus placebo group. CONCLUSION: A standard approach to tapering oral corticosteroids was followed in over 80% of patient visits. Oral corticosteroids were associated with significant complaints, while inhaled corticosteroids were well tolerated.
