Combined moderate dose electron beam radiotherapy and topical chemotherapy for cutaneous T-Cell lymphoma.

Between October, 1978 and June, 1979, nine patients with biopsy-proven cutaneous T-Cell lymphoma were treated with combined total-skin electron beam radiation (TSEB) and topical chemotherapy. TSEB was administered using 3.8 MeV electron and dual exposure technique. All patients received skin dose of 400 rad once weekly to a total dose of 2000 to 2400 rad followed by topical chemotherapy with mechlorethamine hydrochloride (HN2) two to four weeks after completion of radiation. A complete response followed TSEB in seven of nine patients, but a relapse of disease activity has subsequently occurred within the first year for all the patients despite adjunct therapy, except for one patient who remains disease free for more than 21 months. Generalized severe erythema developed during or shortly after completion of radiation in six of nine patients, with blistering at the overlapping treatment fields and body folds in four patients. In addition four patients developed diffuse permanent telangiectasia of skin and one patient developed linear sclerosis, telangiectasis and painful ischemic ulceration on the fingertips two years after completion of electron beam therapy. Most patients had evidence of mild depression of lymphocyte responsiveness to Phytohemagglutinin after TSEB. Our conclusion is that the short-term benefits and convenience of this particular technique do not justify the acute and chronic toxicity encountered.

Total skin electron beam and total nodal irradiation for treatment of patients with cutaneous T-cell lymphoma.

Sixteen patients with advanced cutaneous T-cell lymphoma (CTCL) with or without lymph node involvement, but without evidence of extranodal manifestations, were treated with a combination of total skin electron beam therapy (TSEB) and total nodal irradiation (TNI). Fourteen (87%) patients achieved a complete response (CR) lasting from 1 to 84+ months (median, 8+ months) from the completion of treatment. The best results occurred in 6 patients with pretumorous intracutaneous CTCL (Stages IB and IIA) where the CR has lasted in all patients from 8 to 84+ months (median about 27+ months). Conversely, a long-term CR occurred in only one of five patients with tumor-phase intracutaneous CTCL (Stage IIB) and in none of the 5 patients with histopathologically proven nodal involvement (Stage IVA). Radiotherapy was well tolerated with the major toxicity being bone marrow suppression. We conclude that combined TSEB and TNI is a relatively safe and effective treatment for patients with CTCL prior to the development of lymph node involvement. Long-term follow-up is needed to assess the curative potential of this treatment.

Total skin electron beam and total nodal irradiation of cutaneous T-cell lymphoma.

Nineteen patients with cutaneous T-cell lymphoma (CTCL) limited to the skin and/or lymph nodes were treated at Hahnemann University with a combination of total skin electron beam and total nodal irradiation (TSEB + TNI). The patients were classified as Stage Ib (1 patient), Stage IIa (8 patients), Stage IIb (5 patients), and Stage IVa (5 patients). Treatment resulted in a complete response in 100% (14/14) of patients with Stage Ib, IIa, and IIb disease, and a CR in 60% (3/5) of patients with Stage IVa disease. The Stage Ib and IIa patients had an overall survival of 100% and a disease-free survival of 44% at 6 years. Four of the five patients with Stage IIb CTCL relapsed within 3 months after completing TSEB + TNI with an overall survival in the group of 40% at 5 years. The Stage IVa patients all relapsed within 7 months and died of their disease within 50 months of completing treatment. The acute effects of TSEB + TNI were well tolerated, but three patients developed second malignancy (lung, kidney and skin) and one patient developed myelodysplasia, possibly the result of radiotherapy.

The radiation therapy of early stage cutaneous T-cell lymphoma.

Results of different radiotherapy schedules used for early stage (T1-2, N0-1, M0) cutaneous T-cell lymphoma (CTCL) are compared in a series of 45 patients (22 patients treated with high dose total skin electron beam therapy (TSEB) with curative intent, 18 patients treated with palliative radiotherapy, and 5 patients treated with high dose local electron beam). At 3, 5, and 10 years after diagnosis the high dose TSEB treatment group had a probability of overall survival of 91%, 86%, and 75%, respectively, compared with 94%, 88%, and 88% for the palliative treatment group. The complete response (CR) rate for the high dose TSEB treatment group was 82% (18/22), compared with a 57% (4/7) complete response rate for seven patients in the palliative group who received low dose TSEB (less than 25 Gy in 6-7 weeks) followed by daily application of topical mechlorethamine hydrochloride (HN2). However, the probability of continued remission at 3, 5, and 10 years was 44%, 44%, and 33%, respectively, for the high dose TSEB group and 25%, 25%, and 0%, respectively, for the low dose TSEB + HN2 group. The median disease-free survival was 17.5 months for the high dose TSEB group versus 5.5 months for the low dose TSEB + HN2 group. The five patients who were treated with high doses of local electrons to a single local field had an overall survival rate of 80%, a median survival rate of 64 months, and a median length of continued remission of 31 months. These results indicate that high-dose electron beam can result in long-term disease-free survival in patients with localized and limited extent skin involvement with cutaneous T-cell lymphoma.

The treatment of primary intraocular malignancy.

This paper will summarize much of the information derived in an association between The Department of Radiation Oncology of Hahnemann University Hospital and the Oncology Service of Wills Eye Hospital of Thomas Jefferson University, a collaborative effort for the treatment of primary intraocular malignancies that has spanned the last dozen years. In that time we have treated malignant intraocular melanoma by radioactive eyeplaque brachytherapy and have begun to develop a similar program for treatment of recurring retinoblastoma. These experiences will be described.

Radiation therapy for macular degeneration: technical considerations and preliminary results.

PURPOSE: This study was undertaken to assess the toxicity and possible benefits from the administration of low-dose external-beam irradiation for Age-Related Macular Degeneration (ARMD). The premise of the treatment is that radiation induces regression and/or promotes inactivation of the subretinal neo-vasculature, resulting in reabsorption of fluid and blood thus reducing the risk for further leakage or bleeding, as well as subretinal fibrosis. Clinically, the beneficial effect could be translated into stabilization of visual acuity and prevention of progression of the wet type of ARMD with the possibility for some visual improvement. METHODS AND MATERIALS: Allegheny University Hospitals, Hahnemann, Department of Radiation Oncology, treated 278 patients prospectively beginning in January 1995 with low-dose irradiation for wet-type macular degeneration. Two hundred forty-nine patients were treated with a total dose of 14.40 Gy in eight fractions of 1.80 Gy over 10-13 elapsed days, and 27 patients with 20 Gy at 2 Gy per fraction over 12-15 days. The first two patients were treated to a total dose of 10.00 Gy in five fractions of 2.00 Gy. Patients were evaluated at 2-3 weeks and 2-3 months. A percentage (36.7%) of the patients had previously received laser treatments in the study eye, 21.9% once, 5% twice, 9.7% three or more. Subjective visual acuity and toxicity data was collected on all patients. RESULTS: At 2-3 weeks after treatment 195 patients (70%) retained their visual acuity without change, 68 patients (24.5%) stated they had improved vision, and 15 patients (4.8%) stated their vision continued to decrease. Two to 3 months after treatment, 183 patients (65.8%) had no change in their vision, 75 patients (27%) had an improvement in their vision, and 20 patients (7.2%) had a decrease in visual acuity. Transient acute reactions occurred in 14 of the 278 patients treated. CONCLUSION: Our observations in this group of 278 patients support the conclusion that many patients will have improved or stable vision after treatment with low-dose irradiation for age related wet type macular degeneration.

External radiotherapy in macular degeneration: technique and preliminary subjective response.

PURPOSE: This study attempted to assess the toxicity and possible preliminary benefits from the administration of low-dose external beam irradiation for age-related macular degeneration (ARMD). The premise of the treatment is that radiation induces regression and/or promotes inactivation of the subretinal neovasculature which would result in reabsorption of fluid and blood. This would reduce the risk for further leakage or bleeding, as well as subretinal fibrosis. Consequently, the beneficial effect could be translated into stabilization of visual acuity and prevention of progression of the wet ARMD with the possibility for slight improvement. METHODS AND MATERIALS: Allegheny University Department of Radiation Oncology treated 41 patients prospectively from January through October 1995 with low-dose irradiation for wet-type macular degeneration. A total of 39 patients were treated with a total dose of 14.4 Gy in eight fractions of 1.8 Gy/fraction over 10-13 elapsed days. The first two patients were treated with a total dose of 10 Gy in five fractions of 2 Gy. Patients were evaluated at 2-3 weeks and 2-3 months. Some of the patients (36.7%) had laser treatments in the study eye: 21.9% (9) once, 5% (2) twice, 9.7% (4) thrice or more. Subjective visual acuity and toxicity data were collected on all patients. RESULTS: At 2-3 weeks after treatment 29 patients (70%) retained their visual acuity without change, 10 (24.5%) stated they had improved vision, and 2 (4.8%) stated their vision continued to decrease. At 2-3 months after treatment, 27 patients (65.8%) had no change in their vision, 11 (27%) had an improvement in their vision, and 3 (7.2%) had a decrease in visual acuity. Six patients of 41 in the treated group had acute transient side effects. CONCLUSION: Our observations in this group of 41 patients support the conclusion that many patients will have improved or stable vision after treatment with low-dose irradiation for age-related wet-type macular degeneration.

Radiotherapy for unilesional mycosis fungoides.

PURPOSE: To evaluate the treatment outcome and natural history of patients with the diagnosis of unilesional mycosis fungoides, treated according to a prospective radiotherapy protocol in our institution since July 1975. METHODS AND MATERIALS: A total of 325 patients with the diagnosis of mycosis fungoides have been referred to the Department of Radiation Oncology at Allegheny University of Health Sciences from July 1975 through September 1996. Of these, 18 patients (5%) were classified as having unilesional mycosis fungoides and were irradiated with a curative intent using local electron fields. One patient received 22 Gy; 1 patient received 40 Gy, and the rest of the patients 30.6 Gy. Daily fractions ranged from 1.8 to 2.0 Gy. Treatments prior to radiation consisted of topical steroids and/or antifungal creams in the majority of patients, with temporary partial responses. One patient had received 2 years of topical mechlorethamine (HN2) and another patient had received topical carmustine solution (BCNU) without response prior to irradiation. RESULTS: The responses were measured clinically; posttreatment skin biopsy was not performed routinely unless there was clinical evidence of disease persistence. Complete response rate was 100%; all treated lesions cleared completely within 4 to 8 weeks after the completion of radiation. With a median follow-up of 43 months (range 12 to 240 months), 2 relapses have occurred, 2 and 71 months after the completion of radiation. Both relapses were confined to the skin and were remote from the original site. Both relapses responded to topical application of HN2. There have been no recurrences in the irradiated field nor systemic dissemination. No long-term side effects were found related to treatment, and all the patients are currently alive and without evidence of disease. Actuarial relapse-free and overall survival at 10 years are, respectively, 86.2% and 100%. CONCLUSION: Unilesional mycosis fungoides has a long natural history, is possibly the earliest manifestation of a malignant process, and local treatments, including local radiotherapy, result in long-term disease-free intervals and, possibly, cure. Total skin electron beam radiotherapy is not indicated for this disease entity.

Paradoxical changes in iodine-131 scintigraphic findings in advanced follicular thyroid cancer.

We present the findings on iodine-131 (131I) scintigraphy, thallium-201 (201Tl) scintigraphy and quantitative thyroglobulin (QTG) estimation in two patients with follicular carcinoma of the thyroid with extensive metastases. The lesions were initially seen on 131I scintigraphs, but were not subsequently visualized with scanning doses of 131I (5 mCi), while retaining their ability to produce increasing amounts of thyroglobulin and take up 201Tl. Implications in choosing the appropriate diagnostic tests in the management of differentiated thyroid cancer are discussed.

Autologous bone marrow transplantation for advanced stage mycosis fungoides.

Patients with advanced stage cutaneous T cell lymphoma (CTCL) have a median survival of 2-5 years with no currently available curative therapy. This limited pilot study was performed to determine if CTCL patients could undergo autologous bone marrow transplantation (ABMT) as a curative treatment without developing life-threatening infections. Since selection of a chemotherapeutic regimen is essentially empirical at this time, several drug combinations were screened. Total skin electron beam radiotherapy was used prior to transplantation to control the skin disease of four patients. Six patients have been transplanted and all have engrafted normally. Infections that developed after transplantation responded to conventional therapy and were typical of those observed in other patients undergoing ABMT. Five of the six patients had a complete clinical response to ABMT but three of these responses lasted less than 100 days. Two recent patients who were treated with carmustine, etoposide, and cisplatin are alive more than 1 year after transplantation without evidence of active disease. Thus, although this study does not prove the efficacy of ABMT, it does demonstrate that patients with CTCL can undergo ABMT without developing life-threatening infections and that carmustine-etoposide-cisplatin plus ABMT should be evaluated in subsequent studies to treat patients with poor prognosis CTCL.

Plaque radiotherapy for uveal melanoma: long-term visual outcome in 1106 consecutive patients.

OBJECTIVE: To identify clinical predictive factors for visual outcome in a large series of patients who underwent plaque radiotherapy for uveal melanoma. DESIGN: Clinical factors, including patient data, tumor features, and radiation variables, were analyzed for their impact on visual acuity using Cox proportional hazards regression models. PARTICIPANTS: Patients with uveal melanoma and initial visual acuity of 20/100 or better in the affected eye who were treated with plaque radiotherapy between July 1976 and June 1992. MAIN OUTCOME MEASURES: Two end points were used to evaluate posttreatment visual acuity: (1) final visual acuity (good [20/20-20/100] vs poor [20/200 to no light perception]) and (2) loss of visual acuity (minimal [<5 lines Snellen visual acuity] vs moderate [> or = 5 lines Snellen visual acuity]). RESULTS: Of 1300 consecutive patients with uveal melanoma treated by plaque radiotherapy, 1106 had a visual acuity of 20/100 or better at the time of treatment. In this group, poor visual acuity was found in 34% at 5 years and 68% at 10 years of follow-up. From multivariable analysis, clinical factors that best predicted poor visual acuity were increasing tumor thickness, proximity to foveola of less than 5 mm, notched plaque shape, tumor recurrence, patient age 60 years or older, subretinal fluid, cobalt isotope, anterior tumor margin posterior to equator, and worse initial visual acuity. Moderate loss of visual acuity of 5 Snellen lines or more was found in 33% at 5 years and 69% at 10 years of follow-up. From multivariable analysis, clinical factors that best predicted moderate visual acuity loss included increasing tumor thickness, worse initial visual acuity, notched plaque shape, tumor recurrence, proximity to foveola of less than 5 mm, patient age of 60 years or older, subretinal fluid, and diabetes mellitus or hypertension. When analyzing visual outcome with regard to tumor thickness, ultimate poor visual acuity of 20/200 or worse at 5 years was found in 24% with a small melanoma (< or = 3.0 mm), 30% with a medium melanoma (3.1-8.0 mm), and 64% with a large melanoma (>8.0 mm). When analyzing visual outcome with regard to tumor proximity to visually important structures, tumors less than 5 mm from the optic disc or foveola demonstrated poor visual acuity in 35% at 5 years, whereas those 5 mm or more from the optic disc and foveola showed poor visual acuity in 25% at 5 years. CONCLUSIONS: Ultimate visual acuity after plaque radiotherapy for uveal melanoma depends on many factors, including patient age and general health, initial visual acuity, tumor location and size, subretinal fluid, radioactive isotope, and final tumor control. At 10 years' follow-up, 68% of patients demonstrate poor visual acuity. Visual acuity is most effectively preserved in eyes with small tumors outside a radius of 5 mm from the optic disc and foveola.

Hodgkin's disease. Results from a program in radiation therapy.

From January 1965 to December 1975, 122 patients diagnosed with Hodgkin's disease, Stage I-A, II-A, and III-A were treated at the Department of Radiation Therapy at Hahnemann Medical College and Hospital. Twenty-five patients with Stage I-A, 54 patients with Stage II-A, and 43 patients with Stage III-A were accepted for treatment. Retrospective analysis was made to define the impact of the cell type, clinical and pathologic stage, and tumor bulk on prognosis. Of the 25 patients with Stage I-A Hodgkin's disease, 13 were clinically staged and 12 pathologically staged. Nine patients received extended-field radiation therapy with the overall relapse-free survival of 100% at 5 and 9 years; 16 patients received mantle radiation only, with overall survival of 84% and relapse-free survival of 68% at 5 and 10 years. Of 54 patients with Stage II-A Hodgkin's disease (32 clinically staged and 22 pathologically staged), six patients received involved field radiation therapy with overall survival of 68 and 49% at 5 and 10 years, and relapse-free survival of 33 and 17% at 5 and 10 years. Nineteen patients received limited-field radiation therapy (mantle or inverted Y) with overall survival of 49% at 5 and 10 years, and relapse-free survival of 42 and 31% at 5 and 10 years, and 29 patients received extended-field radiation therapy (mantle and para-aortic or TNI) with overall survival of 88% at 5 and 10 years, and relapse-free survival of 82 and 73% at 5 and 10 years. The overall and relapse-free survival at 5 and 10 years in 22 patients pathologically staged II-A (treated by different techniques) are 95 and 75%. Forty-three patients with Stage III-A Hodgkin's disease (treated with different techniques) reveal an overall survival of 79 and 64% at 5 and 10 years, and relapse-free survival of 58 and 45% at 5 and 10 years. Complications consisted of six patients with overt symptoms of hypothyroidism, two patients with peripheral neuropathy, one patient with radiation myelitis, and two patients with symptoms of leukoencephalopathy. Two patients developed second malignancies.

Testicular seminoma. Results of a program of megavoltage irradiation.

Between April 1962 and March 1984, 61 patients with a diagnosis of testicular seminoma were seen at Hahnemann University Hospital. Of these patients, 52 had long-term follow-up after definitive treatment with megavoltage irradiation. In 30 patients, disease was classified as stage I, in 21 patients, stage II, and in one patient, stage III. Treatment techniques are described. Overall relapse-free survival rate for all stages was 92% with an adjusted survival rate of 96%. Treatment policies for each stage are presented.

Radiation therapy for adjunctive treatment of adrenal cortical carcinoma.

Adrenocortical carcinoma is a rare disease which is primarily approached surgically. There have been few reports of the efficacy of radiation therapy and, for the most part, these have been anecdotal. This paper reports on the potential adjuvant role of radiation therapy after surgical excision of primary adrenal cortical carcinoma and also comments about the efficacy of palliative radiation therapy for metastases. We have identified eight patients treated for adrenal cortical carcinomas at Hahnemann University Hospital (HUH) from 1962 until the present and have also identified five patients with the same diagnosis at Philadelphia General Hospital (PGH) from 1962 until its close in 1975. These two groups are examined separately. In the PGH group, in which two patients were diagnosed at autopsy and only one patient was treated by radiation therapy, the median survival was between 0 and 1 month for Stage IV disease with the only patient surviving to 6 months being that patient receiving radiation therapy. In the HUH group, five of eight patients were treated adjunctively after diagnosis, one was not and two received palliative therapy. The median survival for treated Stage III patients was between 34 months and 7 years. The suggestion, based on a limited patient series, is that patients treated postoperatively to the tumor bed and nodal areas in Stage III disease may have improved survival over historic series and improved local control.

Intracavitary brachytherapy for squamous cell carcinoma of the esophagus.

From September 1983 through January 1989, 8 patients with a diagnosis of squamous cell carcinoma of the esophagus AJCC stages I to III, were treated with intracavitary brachytherapy following external irradiation. Within 3 months after completion of treatment, there was radiographic evidence of complete response in 6 of the 8 patients. None of the responders recurred locally. All the patients have died, with a mean survival of 17 months. One patient died of a stroke 2 1/2 years after completion of treatments without clinical evidence of esophageal cancer. Treatment was well tolerated, with minimal acute toxicity, and one patient developed stricture at the site of tumor, which was successfully treated by dilatation. Addition of systemic chemotherapy to this regimen warrants investigation.

Extracorporeal photopheresis and recombinant interferon alfa 2b in Sezary syndrome. Use of dual marker labeling to monitor therapeutic response.

The purpose of this pilot study was to evaluate the role of recombinant interferon alfa 2b (rIFN-a) as adjunct immunomodulatory therapy in patients with Sezary syndrome who were considered unlikely to respond to ExP alone. Six patients were treated with rIFN-a in doses ranging from 3 to 20 million units three times weekly in addition to two consecutive photopheresis treatments every 4 weeks. In addition, to better measure the effect of treatment on circulating neoplastic T-cells, cryopreserved lymphocytes were studied by two-color immunofluorescence and flow cytometry, using anti-CD4 combined with anti-CD29, anti-CD45RA, or anti-CD7. Minimal clinical improvement was observed in 4 patients treated with low doses of rIFN-a (3 to 5 million units TIW), and the response was sustained in only 1 patient. However, a clinically significant and sustained improvement did occur in 1 patient after the dose of rIFN-a was increased (20 million units TIW). Although the encountered toxicity profile from combined ExP/rIFN-a therapy was similar to that expected for ExP or comparable doses of rIFN-a given separately, treatment was discontinued in 2 patients because of adverse effects. Three antibody pairs, i.e., CD4+CD7-, CD4+CD29+, and CD4+CD45RA- subsets, appeared to be useful to monitor changes in blood Sezary cells during treatment. We conclude that the combination of ExP and low doses of rIFN-a does not appear to be effective for patients with advanced Sezary syndrome in this small patient series. However, escalation of interferon dose may be beneficial as shown in one patient, but it cannot be discerned whether the response was due to a combination of therapies, or whether the same therapeutic response would have been achieved with the higher doses of rIFN-a alone. Moreover, while none of the antibody pairs is unique for Sezary cells, the CD4+CD7- subset in appropriate patients provided a good objective measure of response and correlated well with visual Sezary cell counts.

Cancer of the esophagus following allogeneic bone marrow transplantation for acute leukemia.

The successful development of allogeneic bone marrow transplantation (BMT) has markedly improved the treatment results for acute leukemia and other hematologic diseases. However, significant complications are associated with this procedure including the development of chronic graft versus host disease (GVHD). Treatment for this condition requires chronic immunosuppression which can lead to the development of second cancers. It is well known that immunosuppression is associated with a variety of tumors, most commonly lymphoma. The development of solid tumors appears to be less common but follow-up studies of patients treated for Hodgkin's disease demonstrate a rising incidence of solid tumor development after a delay of 5 to 10 years. We describe a patient recently treated for a squamous cell carcinoma of the esophagus which developed 5 years after an allogeneic BMT for acute myelogenous leukemia (AML). The patient had been treated with immunosuppressants for chronic GVHD. The clinical course is described and the literature is reviewed regarding recent experience with the development of solid tumors following allogeneic BMT. The majority of second tumors following BMT are lymphomas and leukemias. Secondary solid tumors are less common, but the incidence appears to increase over time. Squamous carcinomas are most common and a preparative regimen combining radiation and chemotherapy may increase risk. Careful long-term follow-up of BMT is essential in order to detect second tumors at an early stage.

Concomitant irradiation and dose-escalating carboplatin for locally advanced carcinoma of the uterine cervix: an updated report.

The combination of radiotherapy and carboplatin is associated with high response rates among women who have cervical cancer. To improve control rates for patients who have locally advanced carcinoma of the uterine cervix, oncologists have explored combinations of radiotherapy and chemotherapy. Carboplatin is an analogue of cisplatin, with similar efficacy against cervix cancer and a toxicity profile that is theoretically appealing for this group of patients because it is not nephrotoxic. Fifteen women with International Federation of Gynecology and Obstetrics (FIGO) stages IB2 through IIIB or recurrent carcinoma of the cervix were treated with megavoltage irradiation and weekly intravenous carboplatin (7 women, 60 mg/m2; 8 women, 90 mg/m2). Response was documented among all patients treated at 60 mg/m2 (three complete responses, four partial responses) and in 6 women treated with 90 mg/m2 (four complete responses, two partial responses). The two nonresponders in the series presented with recurrent glassy cell carcinoma of the cervix. All patients completed the planned course of therapy without the need for treatment interruption. At 60 mg/m2, one dose of carboplatin was withheld because of grade 2 thrombocytopenia. At 90 mg/m2, one case of grade 2 leukopenia was documented. The leukocyte counts remained within normal limits for all 3 patients who were irradiated through extended portals that encompassed the paraaortic nodes (2 women, 60 mg/m2; 1 woman, 90 mg/m2). To date, 2 of 7 patients treated at the lower dose level have died of disease (one local progression and distant failure at 11 months, one distant failure alone at 6 months). The remaining patients treated at 60 mg/m2 are alive at a median of 24 months (range, 21-37 months). Among those treated at the higher dose level, 1 patient is alive with local and distant failure at 14 months, and 1 woman succumbed to local and distant disease at 4 months. The remainder are alive at a median follow-up of 6 months (range, 2-10 months). The regimen was unsuccessful in salvaging women with recurrent glassy cell carcinoma. We conclude that the combination of radiotherapy and carboplatin can be safely delivered at both of the chemotherapy schedules studied. The regimen should not be offered to women who have recurrent glassy cell tumors. To prove the efficacy of this approach, phase III testing should be considered that compares the combination of agents to irradiation alone.

Treatment of cutaneous T-cell lymphoma.

Intensive treatment of cutaneous T-cell lymphoma with modalities directed only at skin manifestations appears to cure up to 40 per cent of patients with early, limited skin involvement. For patients with widely disseminated skin lesions, the dermatologist often must choose a treatment regimen with both cutaneous and systemic effects in order to provide effective long-term control. Although vigorous combined-modality therapy results in improved disease-free survival intervals, it also has significant associated morbidity. When compared with less intensive treatment regimens, it is not clear at this time whether such combined-modality therapy improves either the cure rate or overall survival intervals of patients with early disease. For this reason, the authors recommend a conservative treatment program initially for most patients unless there is clinical evidence that the patient has biologically aggressive disease.

Clinical treatment planning in gynecologic cancer.

Treatment planning in gynecologic cancer is a complicated and difficult procedure. It requires an adequate preoperative assessment of the true extent of the patient's disease process and oftentimes this can be achieved not only by conventional studies but must employ surgical exploratory techniques in order to truly define the extent of the disease. However, with contemporary sophisticated treatment planning techniques that are now available in most contemporary departments of radiation oncology, radiation therapy is reemerging as an important and major treatment technique in the management of patients with gynecologic cancer.
