Abstract
Hepatosplenic T-cell lymphoma (HSTCL) is a rare form of peripheral T-cell lymphoma. It is associated with an aggressive clinical course, a poor response to conventional treatment, and an exceedingly high mortality rate. Recent reports suggest an excessive number of cases of HSTCL in young patients with Crohn's disease who are treated with thiopurines (azathioprine or 6-mercaptopurine [6-MP]) either in conjunction with or without agents that inhibit tumor necrosis factor-alpha (TNF-alpha). Herein, we describe the case of an 18-year-old man with Crohn's disease who developed HSTCL after 5 years of 6-MP treatment. He died 7 months after diagnosis from chemotherapy-refractory lymphoma. Through a literature review, we identified 28 cases of HSTCL in Crohn's patients. All patients were treated with azathioprine or 6-MP; 22 of 28 (79%) received concomitant treatment with infliximab, and 3 of these 22 patients later received treatment with adalimumab. The median age at diagnosis of HSTCL was 22 years (range, 12-40 years). The median survival for all patients was 8 months (range, 5 days-31+ months), with only 1 patient achieving remission. Additional research is needed to better understand the role of thiopurines and TNF-alpha inhibitors in promoting HSTCL and what can be done to prevent and treat this devastating malignancy in young patients with Crohn's disease.

Abstract
In the highly active antiretroviral therapy era, an increasingly large number of HIV-infected patients are developing non- AIDS-defining cancers (NADCs). As patients survive longer, long-term therapy-related complications take on greater importance. Herein, we describe a patient with AIDS who presented to medical attention with pancytopenia 48 months postchemotherapy with etoposide, prednisone, vincristine, cyclophosphamide, doxorubicin, and rituximab (R-EPOCH) for diffuse large B-cell lymphoma. Bone marrow biopsy showed a moderately hypocellular marrow; 51% of the nucleated cells were blasts with myelomonocytic differentiation. Cytogenetic studies revealed an abnormal karyotype with deletion of the long arm of chromosome 11 (11q21) and 2 additional copies of the MLL gene attached to the short arms of chromosome 10 in 80% of the metaphase cells examined. With the diagnosis of therapy-related acute myeloid leukemia (AML) secured, he began induction chemotherapy with idarubicin and cytarabine. Two weeks later, he died of fungal septicemia and multiorgan failure. Through a literature search, we were able to identify 4 additional cases of therapy-related AML in AIDS patients following chemotherapy for lymphomas. The median age of these patients at the time of AML diagnosis was 39 years (range, 33-59 years), the median time from the treatment of lymphoma to AML was 18 months (range, 11-48 months), and the median survival following induction chemotherapy was 4 weeks (range, 2-16 weeks). With many HIV-infected patients surviving alkylator and topoisomerase inhibitor-based treatment and radiation therapy for AIDS-defining cancers and NADCs, long-term follow-up for therapy-related complications assumes greater importance.

Abstract
BACKGROUND Patients infected with Human immunodeficiency virus (HIV) living longer with antiretroviral therapy (ART) are more likely to develop non-AIDS-defining cancers such as adenocarcinoma of the colon. There have been limited case reports regarding HIV-associated colon adenocarcinoma. The aim of this study was to characterize the clinicopathologic findings and outcome in a series of HIV-infected patients diagnosed and treated for colon adenocarcinoma. PATIENTS AND METHODS A retrospective study involving HIV-related colon adenocarcinoma was performed. Cases were accrued from the personal archives and published case reports. Data regarding demographics, HIV acquisition, ART use, immunosuppression, cancer location, pathology, and outcome were extracted and analyzed. RESULTS A total of 17 patients were identified, including 7 personal cases. Patients were of average age 43 years (range, 25-67 years) and predominantly male (male:female ratio, 14:3). Most carcinomas (57%) involved the right colon, were largely TNM stage 4 cancers (47%), and, when present, metastases were mainly to the liver. Many (47%) individuals died within 1-26 months after their cancer diagnosis. Immunosuppression (AIDS diagnosis and/or CD4+ < 500 cells/mm3) did not appear to correlate with tumor grade, stage, or an adverse outcome. CONCLUSION These data show that HIV-infected patients with adenocarcinoma of the colon tend to be young men with a high incidence of right-sided involvement. Additional research is needed to determine if screening HIV-infected individuals for colon cancer should include younger patients and involve the entire colon.

Abstract
BACKGROUND Chronic human immunodeficiency virus (HIV) infection is associated with an increased incidence of Non-Acquired Immunodeficiency Syndrome (non-AIDS) defining cancers. To date, only a limited number of cases of bladder cancer have been linked with HIV infection. We sought to describe the clinical characteristics of HIV-associated bladder cancer. METHODS A retrospective study was performed involving HIV-positive patients with bladder cancer, combining cases from multiple institutions with published case reports. Data regarding patient demographics, HIV status, clinical presentation, pathology, cancer treatment, and outcome were analyzed using descriptive statistics. RESULTS Eleven patients were identified with a median age of 55 years (range, 33-67). The median CD4+ count at cancer diagnosis was 280 cells/mm3 (range, 106-572 cells/mm3). Six patients (55%) had a known risk factor for bladder cancer, and nine (82%) presented with hematuria. Ten patients had transitional cell carcinoma, and most had superficial disease at presentation. Treatment included mainly transurethral resection of bladder tumor followed by a combination of local and systemic therapies. One patient received intravesical bacillus Calmette-Guèrin (BCG) without complication. Several patients (55%) were alive following therapy, although many (64%) suffered from local relapse and metastatic disease. CONCLUSION Bladder cancer is part of the growing list of cancers that may be encountered in patients living longer with chronic HIV-infection. Our patients presented at a younger age and with only mild immunosuppression, however, they experienced an expected course for their bladder cancer. Hematuria in an HIV-infected patient warrants a complete evaluation.

Abstract
Objective: To compare the clinical course of patients with AIDS-related Kaposi’s sarcoma (KS) with CD4 counts >300 cells/mm3 and undetectable HIV viral loads (VLs) to patients with AIDS-KS with lesser CD4 counts and detectable HIV VLs. Methods: We retrospectively analyzed a cohort of 91 patients with AIDS-KS in a multispeciality clinic. We used χ2 and Student t tests to analyze intragroup differences; survival was determined by Kaplan-Meier analysis. Results: Twenty (22%) of the 91 patients had newly diagnosed, persistent or progressive KS despite CD4 counts >300 cells/mm3 and undetectable HIV VLs. Age, gender, ethnicity, mode and duration of HIV acquisition, type of antiretroviral therapy (ART), and KS therapy did not differ significantly (P ≤ .005) between this group and the remaining 71 patients. Although tumor stage and response to KS therapy were similar, there was a significantly greater risk of death among the patients with CD4 counts <300 cells/mm3 and detectable HIV VLs (P = .048). Conclusions: In the highly active antiretroviral (HAART) era, a substantial proportion of patients with KS had undetectable HIV VLs and CD4 counts greater than the level typically associated with opportunistic diseases. They required systemic therapy to control their KS but were significantly less likely to die and demonstrated a trend toward better 15-year survival than patients having KS with lesser CD4 counts and detectable HIV VLs.

Abstract
Anal dysplasia caused by human papillomavirus (HPV) infection is common in the HIV-infected population and is a precursor to squamous cell carcinoma of the anus (SCCA). Herein, we describe our initial experience in assessing the frequency and severity of anal intraepithelial neoplasia (AIN) in a newly formed anal dysplasia clinic in Seattle. During a 7-month period, 150 HIV-positive men were evaluated by digital rectal examination and high-resolution anoscopy (HRA). Forty-seven patients of the 122 patients who underwent biopsy (39%) had biopsy-identified low-grade AIN, and 47 (39%) had high-grade AIN (HGAIN). Two patients with HGAIN were referred for surgical treatment and were further noted to have microinvasive SCCA. No patient reported significant post-HRA biopsy complications. Patient tolerance and acceptance of AIN screening was good, and the majority of those who underwent screening have been adherent to recommended follow-up examinations and treatment. The clinic is expanding rapidly, with excellent community and provider support. We anticipate that the anal dysplasia clinic will enable our institution to participate in emerging HIV- and HPV-related AIN clinical trials.

Abstract
Plasmablastic lymphoma (PBL) is a rare form of diffuse large B-cell lymphoma characterized by weak/absent expression of conventional B-cell markers and strong expression of plasma cell markers. It is strongly associated with human immunodeficiency virus (HIV) and Epstein Barr virus infection, and shows an unusual tropism to the oral cavity. Herein we describe a patient with AIDS who presented with weight loss and dysphagia owing to a large gastroesophageal mass. His radiographic and endoscopic findings and long history of cigarette consumption suggested carcinoma. Biopsy demonstrated a poorly differentiated tumor stained negatively to routine lymphoid markers including CD20. However, gene rearrangement studies confirmed a B-cell process and a more detailed immunohistochemical analysis revealed the cells stained positively for CD138 (plasma cell antigen). These findings were diagnostic of PBL. Our report reviews the wide differential diagnosis of PBL and underscores the importance of a broad array of viral and molecular studies needed to establish this diagnosis.

Abstract
Intensive chemotherapy for human immunodeficiency virus (HIV)-associated non-Hodgkin lymphoma (NHL) and Hodgkin lymphoma (HL) has resulted in durable remissions in a substantial proportion of patients. High-dose chemotherapy and autologous stem cell transplantation (AuSCT), moreover, has resulted in sustained complete remissions in selected patients with recurrent chemosensitive disease. Based on a favorable experience with dose-reduced high-dose busulfan, cyclophosphamide, and AuSCT for older patients with non-HIV-associated aggressive lymphomas, an AIDS Malignancy Consortium multicenter trial was undertaken using the same dose-reduced busulfan and cyclophosphamide preparative regimen with AuSCT for recurrent HIV-associated NHL and HL. Of the 27 patients in the study, 20 received an AuSCT. The median time to achievement of an absolute neutrophil count (ANC) of >or= 0.5 x 10(9)/L was 11 days (range, 9-16 days). The median time to achievement of an unsupported platelet count of >or= 20 x 10(9)/L was 13 days (range, 6-57 days). One patient died on day +33 posttransplantation from hepatic veno-occlusive disease (VOD) and multiorgan failure. No other fatal regimen-related toxicity occurred. Ten of 19 patients (53%) were in complete remission at the time of their day +100 post-AuSCT evaluation. Of the 20 patients, 10 were alive and event-free at a median of 23 weeks post-AuSCT. Median overall survival (OS) was not reached by 13 of the 20 patients alive at the time of last follow-up. This multi-institutional trial demonstrates that a regimen of dose-reduced high-dose busulfan, cyclophosphamide, and AuSCT is well tolerated and is associated with favorable disease-free survival (DFS) and OS probabilities for selected patients with HIV-associated NHL and HL.

Abstract
A 40-year-old male presented to medical attention with Pneumocystis jiroveci pneumonia and HIV infection. His CD4+ count was 18 cells per microliter and his HIV viral load (VL) was more than 400,000 copies milliliter. After 3 weeks of antibiotic therapy, he continued to have global cognitive deficits. A brain imaging study showed a right temporal mass, which on biopsy proved to be primary central nervous system lymphoma (PCNSL). He began highly active antiretroviral therapy (HAART) but declined palliative whole-brain radiotherapy (WBRT). Four months later, his CD4+ count had improved to 153 cells per microliter and his HIV VL was less than 75 copies per milliliter. At 36 months follow-up, he remained in complete remission (CR). Through a literature review, we identified 4 additional PCNSL patients who achieved prolonged remission after the initiation of HAART. One patient required WBRT and ventriculo-peritoneal shunting for signs and symptoms of obstructive hydrocephalus. The other 3 patients presented with stable neurologic findings and were treated with HAART alone. The median initial CD4+ count for these patients was 50 cells per microliter (range, 2 to 220 cells per microliter). All 5 remained in CR with a median follow-up of 23.5 (range, 13 to 36) months. For patients who present with PCNSL as their initial AIDS-defining event, stable neurologic findings, and effective HAART options, initial treatment with HAART alone may be possible, reserving WBRT and corticosteroids for those who show signs of impending neurologic demise. Chemotherapy and other novel approaches could also be considered for selected patients with lesser degrees of immune suppression and high baseline functional status.

Abstract
Despite the decrease in HIV-associated morbidity and mortality with the advent of highly active antiretroviral therapy (HAART), the incidence of AIDS-related lymphoma (ARL) has not decreased as significantly. Therefore, we compared epidemiologic, immunologic, and clinical characteristics of patients diagnosed with ARL in the pre-HAART and HAART eras. We used the Adult and Adolescent Spectrum of HIV-Related Diseases database of Public Health-Seattle and King County to determine incidences and trends among patients with ARL in Seattle/King County, WA. We noted a significant decrease in the incidence of HAART-era patients with ARL (36.6 vs. 8.4 per 1000 person-years). The percentage of women (2% vs. 14%), minorities (black patients 9% vs. 29%; Hispanic patients 6% vs. 21%; Native American patients 0 vs. 14%), and individuals originating from outside the United States (10% vs. 29%) increased significantly. There was also a significant increase in patients diagnosed with ARL at CD4+ counts > or = 200 cells/microL (3% vs. 21%) and a large decrease in median HIV-1 viral loads at ARL diagnosis (264,667 copies/mL vs. 35,500 copies/mL). Median survival time increased from 3 months to 13 months, and there was a significant decrease in comorbid opportunistic illnesses (83% vs. 36%). In conclusion, ARL incidence decreased significantly and patient profiles changed substantially in the Seattle/King County ASD project. HAART-era patients with ARL were more likely women, minorities, have improved immunologic status, and fewer comorbid opportunistic illnesses. This changing profile of patients with ARL parallels larger changes seen among the general AIDS population in the HAART era.

Abstract
PURPOSE To evaluate in a pilot study the safety and efficacy of liposomal doxorubicin, cyclophosphamide, and etoposide (LACE) when combined with antiretroviral therapy (ART) in patients with AIDS-related lymphoma (ARL). The impact of HIV viral control on therapy and survival was also assessed. PATIENTS AND METHODS Between 1994 and 2005, 40 patients at Virginia Mason Medical Center were diagnosed with ARL. Twelve received LACE every 28 days. All patients received intrathecal chemoprophylaxis, ART, and G-CSF. RESULTS The median patient CD4+ count was 190 cells/microl (range, 20-510 cells/microl), and the median HIV viral load (VL) was 61,613 copies/ml (range, <50-500,000 copies/ml). Seven patients (58%) had an International Prognostic Index score of 3 or 4. Six patients (50%) were ART-naïve, five were viremic despite ART, and one had an undetectable HIV-1 VL. Nine patients (75%) achieved a complete response (CR), and median overall survival was 107 months. At a median follow-up of 46 months, the recurrence-free survival rate was 50%. Two patients died from relapsed/refractory ARL and one patient achieved a CR with salvage therapy. One CR patient died from complications of pneumonia, and another CR patient died from uncertain causes 5 years after treatment. Grade 3 or 4 neutropenia occurred in 23 of 61 (38%) chemotherapy cycles. Hospitalization was required after 5% of treatment cycles due to neutropenic fever. CONCLUSION LACE is an effective and tolerable treatment for ARL. HIV viral control can be maintained in the majority of patients during and after completion of LACE.

Abstract
BACKGROUND Monoclonal gammopathy of undetermined significance (MGUS) is unusual in the general population aged <60 years. Various reports indicate a much higher incidence of monoclonal gammopathy among human immunodeficiency virus (HIV)-infected patients and a significantly younger age at diagnosis. We sought to describe the laboratory findings and clinical course of MGUS, including association with plasma cell disorders, other malignancies, and infections, in 25 HIV-infected patients with a detectable serum monoclonal protein. METHODS We reviewed the patients' demographic characteristics, stage of HIV infection, and clinical course. Laboratory studies included determination of CD4(+) T lymphocyte cell counts, HIV type 1 loads, and quantitative immunoglobulin levels; serum and urine protein immunoelectrophoresis; and determination of serum viscosity indices. Skeletal surveys and bone marrow biopsies were performed in selected cases. RESULTS Twenty-four of 25 patients were male, and the median age of patients was 50 years (range, 21-69 years). The median CD4(+) T lymphocyte count was 350 cells/ microL (range, 40-1029 cells/ microL; mean, 355 cells/ microL), and the median HIV load was <75 copies/mL (range, <50 to 100,000 copies/mL; mean, 20,800 copies/mL). Thirteen of 25 patients had HIV viremia, despite receiving highly active antiretroviral therapy (HAART). After a mean follow-up duration of 21 months, 7 patients (28%) received a diagnosis of a malignancy (multiple myeloma, in 1 patient; non-Hodgkin lymphoma, in 1; Hodgkin lymphoma, in 1; Kaposi sarcoma, in 2; and plasmacytoma, in 2). Ten patients were coinfected with hepatitis B virus and/or hepatitis C virus; 6 were anemic. No patients developed renal failure or hypercalcemia. Nine (56%) of 19 evaluable patients had a decrease of serum monoclonal protein (mean, 0.5 g/dL) while receiving HAART. CONCLUSIONS Patients in our study were characterized by the detection of a monoclonal protein at a younger age and the increased presence of other viral infections (infection with hepatitis B or C virus or Kaposi sarcoma herpesvirus) than is typically seen in an HIV-uninfected cohort. CD4(+) T lymphocyte counts were relatively robust. HAART appeared to have a favorable impact on the serum monoclonal protein level in 9 patients. Long-term follow-up is needed to better define the natural history of MGUS and the link to other possible contributing factors.

Abstract
Purpose Matrix metalloproteinases (MMPs) are involved in tumor metastasis and are overexpressed in Kaposi's sarcoma (KS) cells. In a phase I trial of the MMP inhibitor COL-3 in patients with AIDS-related KS, the drug was well tolerated, KS regression was observed, and MMP-2 levels decreased significantly in responders compared with nonresponders. The aim of this trial was to extend these initial observations. Patients and Methods This was a randomized, parallel-group, phase II study. COL-3 was administered orally once daily at one of two doses (group A received 50 mg and group B received 100 mg) to patients with AIDS-related KS. Antiretroviral therapy was permitted but not required. Serial tumor assessments and plasma levels of MMPs were obtained. Study end points were progressive KS and recurrent dose-limiting toxicity. Results Seventy-five patients received COL-3: 37 in group A and 38 in group B. Fifty-seven patients (76%) had received prior KS therapy. Thirty-three patients (44%) had more than 50 KS lesions. The response rate in group A was 41%, which was significantly greater than the prespecified target rate of 20% (95% CI, 25% to 58%; P = .003); the response rate of group B was 29% (P = not significant). There were significant declines in MMP-2 and MMP-9 plasma levels from baseline to minimum value with treatment (MMP-2, P < .001; MMP-9, P = .001). The most common adverse events were photosensitivity and rash. Conclusion COL-3, when administered as 50 mg/d, is both active and well tolerated in the treatment of AIDS-related KS. COL-3 is a promising agent for the treatment of this opportunistic neoplasm of AIDS.

Abstract
PURPOSE A consistent association with Epstein-Barr Virus (EBV) distinguishes acquired immunodeficiency syndrome (AIDS)-related primary central nervous system lymphoma (PCNSL) from that which occurs in the general population. Recent descriptions of long-term remissions in patients with posttransplantation EBV-associated PCNSL who received EBV-specific therapy suggest some antitumor effect is anti-EBV mediated. PATIENTS AND METHODS We enrolled 4 patients with AIDS-related PCNSL into a novel antiviral and immunomodulatory protocol. An additional patient was treated in a similar fashion off protocol. Treatment consisted of intravenously administered zidovudine (1.5 g twice daily), ganciclovir (5 mg/kg twice daily), and interleukin-2 (2,000,000 U twice daily). After 2 weeks of therapy, patients were switched to oral ganciclovir (1 g 3 times daily), patient-specific, highly active, antiretroviral therapy, and subcutaneous interleukin-2 (2,000,000 U 3 times weekly). A final patient was treated with intravenous zidovudine and hydroxyurea. All 6 patients had advanced-stage AIDS as reflected by a CD4+ T-lymphocyte cell count of < 50/microL and a detectable human immunodeficiency virus (HIV)-1 viral RNA load (median copies, 135,000/mL; range, 2170-360,000/mL). One of 4 protocol-enrolled patients remains in complete remission with > 4 years' follow-up. RESULTS Three patients died from complications of progressive PCNSL. Two patients treated off protocol exhibited favorable responses and remain in complete remission at 28 months and 52 months, respectively. Grade 3/4 myelosuppression was uniformly noted, but there were no clinically significant hemorrhagic or infectious complications. CONCLUSION We conclude that for patients with AIDS and PCNSL, treatments with dual efficacy against HIV and EBV merit further investigation. Our experience provides a platform for future studies.

Abstract
The objective of this case series and literature review is to characterize the clinical course and prognosis of HIV-infected patients with Kaposi's sarcoma (KS) flare during immune reconstitution inflammatory syndrome (IRIS), a heterogeneous and sometimes fatal disorder of immune perturbation after initiation of highly active antiretroviral therapy (HAART). Medical records of 9 HIV-infected patients with KS flare after virologic and immunologic response to HAART were reviewed from a single institution. An additional 10 cases were abstracted by computerized search of the medical literature. In our single institution series, mean time to onset of KS flare was 5 weeks. Pretreatment mean CD4+ count was 190 cells/mm(3) and mean HIV viral load was 153,934 copies per milliliter. During flare, mean CD4+ count was 256 cells/mm(3) and mean HIV viral load was 1156 copies per milliliter. Similar aggregate results are represented in the literature. Six fatalities are reported, 4 from pulmonary KS and 2 from unrelated causes. Systemic chemotherapy universally led to tumor regression, but was administered in only 10 of 19 cases. In no instance was HAART discontinued. Onset of IRIS-associated KS flare is observed as early as 3 weeks, with most cases diagnosed within 2 months after immunologic and virologic response to HAART. Such a flare does not necessarily portend a poor prognosis. Even for those patients with rapidly symptomatic KS, early systemic chemotherapy is effective in suppressing IRIS-associated flare. Close clinical supervision is warranted for the KS patient initiating, changing, or resuming HAART. Particular vigilance is recommended for pulmonary involvement.

Abstract
We sought to determine the consequences of stopping highly active antiretroviral therapy (HAART) in a group of 41 HIV-infected individuals with undetectable HIV viral loads and CD4+ counts greater than 500 cells per microliter for 6 months or more. Clinical and laboratory parameters were monitored, as was the time to HAART reinitiation. Three months after HAART interruption, the median CD4+ count declined by 162 cells per microliter and HIV viral load increased by 24,000 copies per milliliter. Over the next year, CD4+ counts continued to decrease by an average of 11 cells per microliter per 3-month intervals. In contrast, HIV viral loads remained stable over the same period. Five of 7 patients (71%) with elevated cholesterol levels and 6 of 13 patients (46%) with elevated triglyceride levels had these values normalize after stopping HAART. After a median of 21 months follow-up, 26 of 41 patients (63%) have restarted HAART. Patients with Centers for Disease Control (CDC) HIV/AIDS C classification were more likely to restart HAART than those with A or B classification (p = 0.008). Reasons for HAART restart included clinical events in 8 patients. Fifteen patients restarted HAART for immunologic reasons: CD4+ count less than 300 cells per microliter (n = 7); HIV viral load greater than 55,000 copies per milliliter (n = 3); or both (n = 5). Three patients restarted HAART because of personal preference. Within 4 months, all 26 patients who restarted HAART achieved HIV viral loads less than 50 copies per milliliter. Although patients were able to rapidly achieve nondetectable HIV viral loads after restarting HAART, the inability to foresee clinical events among 8 patients (20%) is disconcerting. We advise caution before HAART interruption, particularly for those patients with a preceding history of significant HIV-related complications.

Abstract
Purpose Since the advent of highly active antiretroviral therapy (HAART), the incidence of Kaposi's sarcoma (KS) among AIDS patients has declined both nationwide and in King County, Washington. We sought to compare clinical parameters of patients diagnosed with KS in the pre-HAART (1990 to 1996) and HAART (1997 to 2002) eras. Methods We used patient data abstracted from the Adult/Adolescent Spectrum of HIV-Related Diseases study of Public Health—Seattle and King County. Results Patients diagnosed with KS in the HAART era (n = 40) were significantly more likely (P < .05) than pre–HAART-era KS patients (n = 366) to be diagnosed with alcohol problems (43% v 18%), noninjection drug use (45% v 18%), injection drug use (25% v 10%), psychosis (25% v 13%), and hypertension (13% v 2%). Although median CD4+ count and HIV-1 viral load at the time of KS diagnosis were not significantly different between the two groups, significantly fewer (P < .01) HAART-era KS patients developed opportunistic illnesses (OIs) during their follow-up. The risk of dying among KS patients diagnosed in the HAART era is significantly lower (P < .01) than for KS patients diagnosed in the pre-HAART era (hazard ratio, 0.24). Conclusion Although HAART-era KS patients in King County were as likely to have a depleted CD4+ cell count and high HIV-1 viral loads at the time of KS diagnosis as pre-HAART KS patients, they survived longer and fewer of them were diagnosed with other OIs. They also had an increased prevalence of substance abuse and mental illness, contributing to a dynamic and changing KS clinical profile.

Abstract
PURPOSE To assess the efficacy and toxicity of combination therapy with gemcitabine and docetaxel in patients with unresectable pancreatic carcinoma. PATIENTS AND METHODS Thirty-four patients with unresectable stage III, IVA, and IVB pancreatic carcinoma were eligible for this study. The first 18 patients received gemcitabine 800 mg/m2 intravenously (i.v.) on days 1, 8, and 15 and docetaxel 75 mg/m2 i.v. on day 1, repeated every 28 days. Due to a high incidence of myelosuppression in this first group, the treatment schedule was modified in the remaining patients to gemcitabine 1,000 mg/m2 i.v. and docetaxel 40 mg/m2 i.v. on days 1 and 8 of a 21-day schedule. The primary study endpoints were objective response rate and duration of survival. RESULTS Ten of 33 evaluable patients achieved a partial response, for an overall response rate of 30.3% (95% CI, 16.21%-48.87%). Partial responses noted in the pancreas and a variety of metastatic sites were maintained for 4 to 12 months (median 6 months). Twelve additional patients (36%) experienced stable disease. The median time to progression was 6 months, and median survival was 10.5 months. The toxicity profile of the modified gemcitabine/docetaxel schedule was more favorable than that associated with the initial regimen, particularly with respect to hematologic toxicity. CONCLUSION The response and survival data reported here for combination therapy with gemcitabine and docetaxel are encouraging given the poor prognosis associated with unresectable pancreatic cancer. These data suggest that gemcitabine plus docetaxel may be more effective than either agent alone in the treatment of pancreatic cancer and warrants further study.
