Treatment Complications

Complications following radiation treatment are typically divided into acute (occurring during or soon after the procedure), subacute (following the acute period), and late (as a result of chronic normal tissue damage from irradiation). Acute complications following prostatic seed implant (such as perineal pain and temporary urinary retention) occur in up to 5% of patients. In the subacute period (2 to 4 months following the procedure), most patients experience some degree of obstructive or irritative uropathy with frequency, urgency, nocturia, and the feeling of incomplete voiding. Late complications can include proctitis, hemorrhagic cystitis, urinary incontinence, or impotence.

At St Elizabeth's Medical Center, we use a standard uropathy scoring system when evaluating patients at follow-up (Table I). Of our first 200 consecutive patients, 89% developed short-term grade 1 or 2 uropathy at 1 month after the procedure. This decreased to 38% by 1 year and 20% by 3 years. Only 8% of patients (16) developed grade 3 uropathy within the first month requiring prolonged medication or surgical intervention. Of these, 40% had undergone combined external beam irradiation plus implant. Six of these 16 patients required TUIP or TURP, and 6 of 16 required prolonged (more than 3 months) catheterization.

Rectal morbidity was also minimal with this procedure. At 6 months, 20 patients (10%) had developed some rectal bleeding that resolved with medical treatment. By 18 months, only 1 of these patients continued to have bleeding. Two additional patients (1%) required fulguration for more active bleeding after the procedure, but at 18 months, they were asymptomatic.

Careful placement, avoiding implanting seeds into the rectum or too close to the urethra, will minimize the risk of patients developing these symptoms. Increased uropathy with doses greater than 400 Gy to a significant portion of the urethra has been reported.[11] Overall, the incidence of side effects is considerably lower with prostate implantation than with other treatments. Table II compares complication rates from prostatic seed implants with complication rates following external beam irradiation or prostatectomy.

Malignant Cutaneous Tumors: Cutaneous Lymphoma

From ACP Medicine OnlinePosted 06/07/2006Allan C. Halpern, MD; Patricia L. Myskowski, MD 

Lymphomas may be of B cell or T cell lineage and may involve the skin primarily or secondarily [see 12:IV Principles of Cancer Treatment — omitted]. B cell lymphomas, particularly non-Hodgkin lymphomas, may involve the skin secondarily in advanced disease. They typically appear as reddish-purple subcutaneous plaques or nodules. Primary B cell lymphomas of the skin are even rarer. They appear as reddish nodules that often remain localized to the skin but may progress to systemic disease. The vast majority of primary cutaneous lymphomas fall into the spectrum of cutaneous T cell lymphoma (CTCL).

CTCL includes mycosis fungoides (MF) and Sézary syndrome, which is a leukemic variant of MF.66,67 MF is the largest subset of CTCL; the two terms, however, sometimes are used interchangeably. Another variant of CTCL is associated with human T cell lymphotropic virus type I (HTLV-I) and is part of the spectra of adult T cell lymphoma/leukemia and peripheral T cell lymphoma.66Epidemiology

CTCL is a rare disorder. In the United States, approximately 1,000 new cases of CTCL are diagnosed annually.66 From 1973 to 1984, the incidence of CTCL rose from 0.19 per 100,000 population to 0.42 per 100,000 population. CTCL primarily affects middle-aged adults; the median age at presentation is 50 years.68 The male-to-female ratio is approximately 2:1; blacks are twice as likely as whites to develop CTCL.68Etiology

Host susceptibility and an environmental antigen, perhaps viral, are hypothesized as playing important roles in the pathogenesis of CTCL.66 Genetic factors may be related to major histocompatibility antigens, such as an increase in HLA-DRB1*11 (formerly HLA-DR5) and HLA-DQB1*03.69 Chronic antigenic stimulation (e.g., infection) may play an etiologic role.66 For example, HTLV-I infection may be an etiologic factor in the development of the peripheral T cell lymphoma variant.66Diagnosis

Clinical Manifestations

The clinical manifestations of MF typically evolve over many months to years. In one classic study, the mean duration of symptoms before diagnosis was 7.5 years.70 Flat, erythematous patches, often scaling and occasionally atrophic, begin most commonly on the trunk and thighs, especially in a so-called bathing-trunk distribution [see Figures 6a — omittedand6b — omitted]. Lesions are asymptomatic or mildly pruritic and may spontaneously remit or respond to topical corticosteroid therapy. Patients may also report improvement after sun exposure. As MF progresses, patches tend to enlarge and thicken into plaques. The color may become dark red; in dark-skinned persons, the lesions may initially be hyperpigmented or hypopigmented and may acquire an ery-thematous or violaceous hue. In advanced MF, tumors may develop or transform to a large-cell lymphoma.66,67,71

In approximately 10% of cases, tumors are the initial presentation of CTCL (tumor d'emblé). Generalized erythroderma with circulating atypical T cells (in Sézary syndrome) is the presentation in 5% of CTCL patients.66,67

Physical examination of patients with suspected CTCL includes complete skin examination, including classification of lesions (patch, plaque, or tumor) and extent of body surface area involved. Lymph nodes, the liver, and the spleen should be palpated.

Skin Biopsy

Skin biopsy is necessary for the definitive diagnosis of CTCL. The presence of atypical lymphoid cells with hyperconvoluted cerebriform nuclei in clusters in the epidermis (Pautrier microabscesses) and a bandlike lymphocytic infiltrate in the upper dermis are diagnostic of CTCL.66,67 The malignant cell is a T cell, with most of the cells expressing the pan-T cell markers CD2, CD3, and CD5, as well as frequent deletion of CD7, CD26, or both.66,67,72 The use of T cell receptor gene rearrangement studies to confirm clonality in early disease may be an aid to diagnosis.66 Neither immunophenotypic studies nor electron microscopy may be considered to be definitively diagnostic of CTCL; clinicopathologic correlation is necessary.

Laboratory Studies

The laboratory evaluation for CTCL includes complete blood count, eosinophil count, Sézary cell count, lactic dehydrogenase level, and liver function tests. Bone marrow biopsy is unnecessary in the absence of circulating leukemic cells. HTLV-I testing should be considered for patients with risk factors or atypical presentations. Lymph node biopsy should be considered for palpable nodes, especially those larger than 2 cm. Abdominal computed tomography or chest radiography may be important in patients with tumors or suspected visceral involvement.Differential Diagnosis

In its early stages, CTCL may resemble any of a number of benign inflammatory disorders (e.g., drug reaction, eczema, psoriasis, or contact dermatitis). These disorders should be ruled out before contemplating therapy.Staging

The staging of CTCL is based on an evaluation of the type and extent of skin lesions and the extent of lymph node, peripheral blood, and visceral involvement.70,71 Early disease is characterized by limited patch or plaque disease (stage IA) or generalized patch or plaque disease without evidence of extracutaneous involvement (stages IB and IIA); more advanced disease is characterized by cutaneous tumors (stage IIB), extracutaneous disease (stage III), and extracutaneous disease involving either lymph nodes (stage IVA) or viscera (stage IVB).Treatment

Topical Therapy

Topical therapy is the mainstay of the treatment of early disease (stage IA, IB, and IIA). Early aggressive therapy with radiation and chemotherapy has not proved to be superior to local approaches in controlling disease or improving survival in patients with limited disease.66,67 A rational approach for treating early limited (or histologically equivocal) disease is topical corticosteroids.73 Topical nitrogen mustard (mechlorethamine), in either aqueous or ointment form, is the most frequently used topical chemotherapy. In one series, the overall response rate to nitrogen mustard was 83%, with a complete response rate of 50%, after a median treatment time of 12 months.74 Median time to relapse was also 12 months.74

Carmustine (BCNU) solution, applied daily to lesions, is another useful regimen. Treatment generally lasts 8 to 16 weeks but has been continued for up to 6 months. Because systemic absorption can result in bone marrow suppression, complete blood counts must be monitored.62 Bexarotene, a topical retinoid, has been shown to be effective in CTCL; it is approved by the FDA for use in CTCL.75

Ultraviolet Radiation

Radiation therapy for CTCL takes several forms, from ultraviolet light to ionizing radiation. UVB is useful in stage I disease. In a retrospective study of 21 patients with stage I disease, narrow-band UVB led to complete remission in 81% of patients and to partial remission in 19%; the mean relapse-free interval was 24.5 months.76

Another effective approach to treatment of CTCL is the combination of psoralen and UVA (PUVA). In one study, 65% of patients with stage I CTCL had complete clinical clearing, with a mean relapse-free interval of 43 months; the disease-free survival rates at 5 and 10 years for stage IA were 56% and 30%, respectively.77 In another study, complete remission was observed in 71% of early-stage patients; in this study, the mean relapse-free interval was 22.8 months.76

Radiation Therapy

Total skin electron beam (TSEB) radiation delivers radiotherapy to the skin surface without a significant internal dose. It is especially useful with plaque disease. Typical doses are 2,400 to 3,600 cGy, fractionated over several weeks with 4 to 9 MeV electron beam radiation.78 Treatment responses are related to CTCL stage79; early-stage (stage IA) patients have a 95% response rate, but 50% will experience relapse within 10 years. TSEB may also be useful in stage IB disease (90% remission rate), but two thirds of patients treated with this modality will experience relapse within 5 years.73 Patients with tumor-stage (stage IIB) CTCL may receive effective palliation from TSEB, especially in combination with other therapies.79

Systemic Therapy

Systemic therapy has been undertaken as primary therapy in advanced CTCL (stages III through IVB); in early-stage disease, systemic therapy is used as part of sequential therapy to promote more durable responses.66,67

Oral bexarotene has yielded response rates of up to 45% in advanced CTCL, and it is approved by the FDA for use in this disease.80 Another systemic therapy used in the treatment of advanced CTCL is denileukin diftitox [DAB(389) IL-2].81 This receptor-targeted cytotoxic fusion protein binds to the IL-2 receptor on T cells; it achieved a 30% response rate in heavily-pretreated patients.81

Extracorporeal photopheresis, which is an accepted therapy for advanced CTCL, appears most useful in erythrodermic CTCL and Sézary syndrome.66,67 In this treatment, the patient is given a photoactivating drug (8-methoxypsoralen), the patient's white blood cells are collected via leukapheresis and irradiated with UVA, and the irradiated cells are returned to the patient intravenously. Advanced CTCL characterized by cutaneous tumors (stage III) or visceral involvement (stage IV) has also been treated with single-agent and combination chemotherapy using methotrexate, adenosine analogues, interferon alfa, and retinoids.66,67,82

Combination Therapy

Early aggressive treatment using TSEB followed by combination chemotherapy provides no survival advantage over sequential topical therapy.83,84 In a randomized controlled trial, 103 patients with MF received TSEB followed by either parenteral chemotherapy with cylophosphamide, doxorubicin, etoposide, and vincristine or sequential topical treatment. Patients receiving combined therapy had a significantly higher rate of complete response than those receiving sequential topical therapy; however, there was no difference in the rates of disease-free and overall survival between the two groups after a mean follow-up of 75 months.83 In an uncontrolled study, multimodality therapy was examined in patients with early and advanced disease. In this study, 95 CTCL patients received in consecutive phases of therapy interferon alfa and oral isotretinoin, TSEB, and maintenance therapy consisting of topical nitrogen mustard and interferon alfa. Patients with advanced disease also received six cycles of combination chemotherapy before TSEB. Although multimodality therapy resulted in high response rates (85% response, 60% complete response), the study provided no evidence that this form of combination therapy could improve the overall survival rates currently achieved with sequential topical therapy.80 In general, the heterogeneity of reported combination therapy regimens in CTCL makes it virtually impossible to compare results.

Future Directions

A number of experimental approaches are being investigated in CTCL, including allogeneic bone marrow transplantation, histone deacetylase inhibitors, monoclonal antibodies, and fusion toxins.67 Other investigative modalities include cytokines such as recombinant IL-12 and IL-2.66Complications

The most serious complications of CTCL are infections. Sepsis from ulcerated cutaneous tumors is a common cause of death. Visceral CTCL may occur, as may transformation to large cell lymphoma in some CTCL patients (39% probability after 12 years).71 In long-term survivors with early disease, local therapies (e.g., TSEB or PUVA) may contribute to the development of other skin cancers (e.g., BCC or SCC) and cataracts.85Prognosis

Many different attempts have been made to classify CTCL into useful prognostic groups. An early and still valid study that used the TNM system identified three major groups: good-risk patients (stages IA, IB, and IIA, with plaque-only skin disease and no lymph node, blood, or visceral involvement [median survival, > 12 years]); intermediate-risk patients (stages IIB, III, and IVA, with cutaneous tumors, erythroderma, or plaque disease and node or blood involvement but no visceral disease or node effacement [median survival, 5 years]); and poor-risk patients (stage IVB, with visceral involvement or node effacement [median survival, 2.5 years]).70

Eosinophilia is also associated with shortened survival.70 Other long-term studies have revealed that stage IA patients do not have a reduced life expectancy and that fewer than 10% of these patients experience disease progression to more advanced stages.86 Survival of patients with generalized patch/plaque MF (stage IB or IIA), at a median of 11.7 years, is significantly worse than that of a race-, age-, and sex-matched control population.87 Gender and race appear to have no effect on survival, but older patients (> 58 years) have shorter disease-specific survivals.68

Sildenafil in systolic heart failure with secondary pulmonary hypertension

Researchers presenting new subject matter on the use of sildenafil in the artistic style of meat unfortunate say the phosphodiesterase 5 (PDE5) inhibitor once known as the “Pfizer riser” is returning with causal agent to its roots in the cardiac area, with benefits that may go beyond pulmonary arterial hypertension (PAH).

sildenafil, point explored as an antianginal medicinal drug, actually gained initial mercantilism message for the handling of erectile dysfunction (as Viagra) and later for primary quill PAH (as Revatio). “Sildenafil took a detour below the belt before orgasm back to where it should be,” Dr Marc Semigran (Massachusetts Top dog Health facility, Boston, MA) quipped to corewire.
Semigran is grownup writer on a worker presented here at the Tenderness Unsuccessful person Company of USA 2006 Scientific Encounter suggesting that viagra may also improve recitation software program and character of life in systolic heart-failure patients with coil PAH.

The rationale for evaluating sildenafil in the mount of viscus failure–as in PAH–stems from observations that PDE5 is the player enzyme responsible for cGMP catabolism in vascular smooth-muscle cells, while chronic LV systolic dysfunction is characterized by impaired nitric-oxide (NO)-cGMP-mediated vasodilation in pulmonary and skeletal-muscle circulatory systems.

Commencement maker on the memorizer with Semigran, Dr Vicar of Christ D Lewis (Massachusetts General officer Hospital), presented results from an interim criticism of the randomized, double-blind, placebo-controlled subject field during an oral “poster highlight” academic term.
As Frederick Carleton Lewis explained in an audience with variety meatwire, he and his colleagues set out to enroll patients with LV dysfunction, a abstract entity that had explicitly been excluded in the viagra for Use in Pulmonary Arterial Hypertension (SUPER) knowledge base that led to sildenafil’s subject matter for PAH.
As such, Clive Staples Lewis et al’s knowledge base enrolled 40 patients with NYHA assemblage 3 or 4 systolic HF and secondary coil PAH, defined as a mean pulmonary arterial somatic sensation >25 mm Hg, and randomized them either to medication or oral cheap sildenafil citrate uptitrated to 50 mg trinity fourth dimension daily for 12 weeks.

Interim results

Carl Lewis et al plan to enroll 40 patients in the report but twenty-four hour period presented data for the no. 28 patients.
In these, said John L. Lewis, patients randomized to viagra (n=14) experienced a 13% placebo-corrected change of state in six-minute-walk interval (p<0.05) as well as significant condition in Minnesota Being with Meat Nonachievement scores, which, he noted, have been shown to independently predict outcomes in HF patients.
There were no significant differences in any adverse events between the two groups, with the objection of infirmary admissions for country natural event, which were significantly lower in the patients taking sildenafil (7 vs 1, p=0.02).

While other systemic vasodilators have been tested in intuition unsuccessful person, Frederick Carleton Lewis believes sildenafil may be particularly potent in the pulmonary vasculature, thereby improving piece of land ventricular functioning.

He and his colleagues are also assessing other effects of the drug, and Lewis doesn’t rule out a role for sildenafil in warmness skip in the interval of PAH, although, he emphasizes, those analyses have not yet been done.

“We’re death to look carefully at remodeling effects, as well as peripheral effects.
Although we’ve been focused on the pulmonary vasculature, it is applicant that this medicament has peripheral effects that are also potentially of use in heart-failure patients–for lesson, improving endothelial computer software in the periphery. . . .
Fortunately, we’re talking about a drug with a long evidence sound recording in humans, as opposed to a brand-new functionary that’s never been looked at, with interloper risks.”

Men Treated with Sildenafil Citrate for Erectile Dysfunction

Prospect: Men with erectile dysfunction (ED) often have low self-esteem, self-assurance, and sexual human relationship restitution.

Lens: We evaluated the effect of viagra citrate and its generalizability across cultures on self-esteem, friendship, and sexual family relationship emotional state in men with ED using the Self-Esteem And Family relationship (SEAR) questionnaire.
Ornamentation: Pooled literary criticism of 2 double-blind, placebo-controlled, flexible-dose trials of sildenafil with identical protocols: 1 was conducted in the United States and the other in Mexico, Brazil, Land, and Japan.
Patients: Men ≥18 old age old with ED.
Measurements: The issue of tending on psychosocial factors associated with ED was determined by semantic role responses to the SEAR questionnaire.
Erectile subroutine was determined using the International Forefinger of Erectile Social function (IIEF) and a global efficacy dubiousness.
Successful sexual sexual intercourse attempts were derived from phenomenon logs of sexual bodily process.
Communication visual aspect sizes were calculated for all concentration outcomes.
Results: Compared with patients who received medicinal drug (n=274), patients who received sildenafil soft  reported significantly greater improvements (P<.0001) in self-esteem, self-confidence, sexual human relationship atonement, and in all sexual software package domains of the IIEF.
Direction essence sizes were large (range, 0.7 to 1.2) for all SEAR components, and advance in psychosocial measures showed moderate to high correlations (range, 0.50 to 0.83, P<.0001) with transmutation in erectile role, assets of successful coition attempts, and global efficacy.
Conclusions: In men with ED from 5 different nations, sildenafil produced substantial improvements in self-esteem, friendship, and sexual human relationship emotional state.
Improvements in these psychosocial factors were observed crossculturally and correlated significantly and tangibly with improvements in erectile purpose.Commencement

The Massachusetts Bay Colony Male Organic process Composition reported that the preponderance of erectile dysfunction (ED) to some grade among men in the United States aged 40 to 70 year is approximately 52% and that the frequency of ED increases 5% per large integer after the age of 40 time of life.
A recent papers of men from Brasil, Italy, Japanese Archipelago, and Malaysia showed that the figure of ED ranged from 18% to 54% for men aged 50 to 70 old age, and a study of Finnish men showed that the number of ED was substantially higher, ranging from 67% to 89% for men 50 to 75 period old. Worldwide, the figure of ED in men aged 40 to 80 time of life is estimated to be 13% to 28%. Although these studies employed different methodologies and cannot be compared with one another directly, they nonetheless show that the figure of ED is quite high.
In suburb, ED impacts a patient’s and his partner’s sexual life and is associated with incurvation, anxiousness, and low self-esteem.

viagra citrate (Viagra®, Pfizer Inc., New York, NY) is the first-in-class phosphodiesterase type 5 inhibitor for the idiom of ED and has been prescribed to more than 20 jillion men in more than 110 countries. Accumulating information from numerous double-blind placebo-controlled and open-label trials suggests that sildenafil is well tolerated and effective for the discussion of ED of diverse cause. Further, successful intervention of ED may be associated with improved measures of calibre of life (QoL).

However, correlations between successful ED communication and changes in psychosocial measures have been difficult to determine because QoL is difficult to define and contains multiple components.
Wine measures of QoL are not able to detect unique changes in men with ED, and ED-specific efficacy instruments fail to savoir-faire relevant psychosocial domains such as self-esteem, assurance, and relationships.

The Self-Esteem And Kinship (SEAR) questionnaire (Appendix I available in the online variant of JGIM) is a validated 14-item papers that underwent rigorous evolution and determination using established psychometric principles.
A psychometric judgement of 98 men with ED and 94 age-matched controls showed discriminant robustness of the SEAR for measuring self-esteem as well as human relationship restitution and trust. A 10-week, open-label papers suggested that the SEAR questionnaire is responsive to effective ED idiom and is a valid instrumental role for detecting psychosocial gains from beneficial positioning. The SEAR was linguistically translated and culturally adapted to assess changes from standard to end of management in relationships, security, and self-esteem.
It is divided into 2 domains: Sexual Relation (items 1 to and Security (items 9 to 14).
The Certainty land has 2 subscales: Self-Esteem (items 9 to 12) and Boilersuit Kinship (items 13 and 14).
An Work-clothes number (items 1 to 14) is calculated from the 2 domains.
Effect categories of each item are based on a 5-point Likert covering and are transformed onto a 0 to 100 measuring device, such that higher scores indicate a more favorable answer:

In this reputation, we time the combined results from patients with ED from 5 different nations who were enrolled in a randomized, double-blind, placebo-controlled field of sildenafil.
