BACKGROUND: We demonstrated that highly active antiretroviral therapy (HAART) increases the toxic effect of cyclophosphamide, vincristine, doxorubicin (DOX) and prednisone (CHOP) in HIV-patients with non-Hodgkin's lymphoma (NHL). To ascertain the cause of increased toxicity, we investigated the pharmacokinetics of DOX in HIV-patients with NHL treated with CHOP with and without HAART. METHODS: Complete pharmacokinetics and pharmacodynamic analysis was determined in 19 patients during 38 cycles of chemotherapy: 19 cycles with CHOP and 19 CHOP + HAART in a crossover-designed study. HAART included protease inhibitors indinavir (IDV) in nine patients, saquinavir (SQV) hard gel in six patients and nelfinavir (NFV) in four patients. RESULTS: No significant effects of HAART on pharmacokinetics parameters of DOX were observed. Similarly, no differential effect on DOX pharmacokinetics among IDV, SQV, and NFV was evidenced. Significant associations (P=0.012) were observed between DOX AUC0-infinity (area under the concentration curve) and G3-G4 WHO haematologic toxicity, in patients treated with CHOP alone, but not in those treated with CHOP + HAART (P = not significant). CONCLUSION: We demonstrated that HAART therapy has no significant effect on DOX pharmacokinetics. DOX AUC appears to be a predictor of toxicity only in patients treated with CHOP alone. Other factors beside DOX plasma levels are detrimental for toxicity after CHOP + HAART. Therefore, pharmacodynamic interactions between HAART and DOX should be considered.
Oxaliplatin is a new, third-generation platinum complex. It has a good safety profile characterized by low hematological-gastrointestinal toxicity. No significant nephro-ototoxicity has been observed. Acute peripheral neuropathy is a common event affecting, as grade 1 or 2, 85-95% of patients. Recently, data on dysphonia toxicity, after the administration of oxaliplatin, has been reported in literature. This toxicity with acute onset can be misunderstood if not carefully looked for. However, it is self-limiting and a non-permanent (grade 1-2) neurotoxic phenomenon, which impairs transiently the quality of life of a percentage of oxaliplatin-treated patients. We report our experience in consecutive patients affected by advanced colorectal cancer treated with oxaliplatin-based chemotherapy. Overall, we observed 13 (16%) cases of dysphonia out of 81 consecutive patients treated with oxaliplatin-based chemotherapy. This toxic effect was self-limiting and all patients recovered rapidly. Nonetheless, a deeper understanding of this phenomenon is essential to give correct information to the patients.

OBJECTIVE: To characterize the therapeutic variables correlated to outcome in 370 patients with primary CNS lymphoma. METHODS: Planned treatment was radiotherapy (RT) in 98 patients, chemotherapy (CHT) in 32, RT followed by CHT in 36, and CHT followed by RT in 197 patients. High-dose methotrexate (HD-MTX; 1 to 8 g/m2) was used in 169 patients and intrathecal CHT in 109. RESULTS: One hundred sixteen patients are alive (median follow-up 24 months), with a 2-year overall survival of 37%. Patients treated with CHT followed by RT had improved survival with respect to patients treated with RT alone. Patients receiving HD-MTX-based primary CHT survived longer than those treated with other drugs. HD-MTX associated with other cytostatics, in particular HD-cytarabine, produced better results than HD-MTX alone. No correlation between MTX dose and survival was found. In patients receiving HD-MTX, consolidation RT or intrathecal CHT did not improve survival. Age, performance status, lactate dehydrogenase serum level, CSF protein level, site of disease, and use of HD-MTX were all predictors of survival. CONCLUSIONS: Combination CHT-RT is superior to RT alone. Patients treated with primary CHT containing HD-MTX exhibited improved survival. In these patients, the addition of HD-cytarabine was associated with a better survival, whereas intrathecal CHT was not correlated to outcome. RT may be unnecessary in patients achieving complete remission after receiving HD-MTX-based primary CHT.
Infusional CDE (cyclophosphamide, doxorubicin, etoposide; iCDE) is one of the most effective chemotherapeutic regimen for human immunodeficiency virus (HIV)-associated non-Hodgkin's lymphoma (NHL), with a complete remission rate of 46% and a median overall survival of 8.2 months (Sparano JA, Blood 1993; 81:2810). Since the majority of HIV-associated NHL are CD20-positive we reasoned that the addition of rituximab to iCDE (R-iCDE) could also improve the poor outcome of these patients. As a first step we investigated the safety of R-iCDE in a phase I/II study. Thirty patients with aggressive HIV-associated NHL were enrolled between June 1998 and October 2000. Characteristics of 29 evaluable patients were: median age: 38 years (range 29-65 years); male sex 24/29; histology: DLCL 16 (55%), Burkitt 10 (35%), ALCL 2 (7%), unclassified 1 (3%); stage: I (35%), II (10%), III (10%), IV (45%); International Prognostic Index: 0, 1 (59%), 2 (24%), 3 (17%), 4, 5 (0); CD4 count: median 132/ mm3 (range 3-470/mm3). Patients received rituximab (375 mg/m2) in conjunction with iCDE (five or six cycles). All patients were treated with G-CSF and highly active antiretroviral therapy (HAART). Twenty-six of 29 patients received treatment as planned, while chemotherapy had to be discontinued in three patients (2 persistent thrombocytopenias, 1 cerebral hemorrhage). Grade 3 or 4 toxicity was observed as follows: neutropenia 79%, anemia 45%, thrombocytopenia 34%, bacterial infection 34%, opportunistic infection 7%, mucositis 17%. A dose reduction was necessary in 22%. Complete remission was achieved in 86% of the patients, partial remission in 4%. Ten percent had progressive disease. After a median follow-up of 9 months the median overall survival is not reached. The actuarial survival at 2 years is 80% and the actuarial progression-free survival is 79%. Four of 29 patients (14%) have died, three from NHL and one from cryptosporidiosis. These findings suggest that the combination of rituximab with iCDE in patients with HIV-associated NHL is safe and feasible and that the addition of the anti-CD20 antibody does not increase the risk for infections. The high complete remission rate also indicates a potential therapeutic benefit and warrants further randomized trials.
In general, it was agreed that high rates of toxicities during treatment occur in the elderly and that there is a frequent occurrence of early relapse. It is clear that different combinations of effective therapies with lower toxicity are required. It was felt, however, that certainly in the 60-70 year age group, approaches should be vigorous to and the same diagnostic and staging procedures as in younger individuals, but with much closer monitoring of toxicity and response to treatment. It was felt that as part of the approach, liberal support with haemopoeitic growth factors (G-CSF) was necessary to reduce prolonged neutropenia. It is important to understand that age in general is not a contrary indication for aggressive treatment and that biologically younger patients under the age of 65 years, in good physical and mental condition, often should be given with stage-adapted treatment, analogous to conventional treatment protocols for the <60 years age group. It was also considered that, in patients who clearly could not accept conventional treatment, study groups could begin to define the best palliative care for patients with pre-existing organ impairment, and that in all situations of assessment, whether in trial or not, there should be a detailed prospective assessment of quality of life parameters.
BACKGROUND: Reported data regarding intraocular lymphoma (IOL) management are anecdotal. Cases of IOL included in an international multicentre series of 378 immunocompetent patients with primary central nervous system lymphomas (PCNSLs) were reviewed. PATIENTS AND METHODS: Staging included slit-lamp examination in 170 patients: IOL was diagnosed in 22 cases (13%). A concomitant brain lesion was detected in 21 cases. Planned treatment was chemotherapy followed by radiotherapy in 13 cases, chemotherapy alone in three and radiotherapy, followed by or not by chemotherapy in five; one patient was not treated. Chemotherapy included high-dose methotrexate in 12 cases. Ten patients received intrathecal chemotherapy. Radiotherapy consisted of whole brain irradiation, followed by or not by a tumour bed boost; ocular irradiation was planned in 15 cases. Irradiation in one patient without brain lesions was limited to the orbits only (50 Gy). RESULTS: IOL was positively correlated to systemic symptoms and meningeal disease. Fifteen patients (71%) achieved an objective response; 16 patients experienced a failure (2-year failure-free survival 34+/-10%). Failures involved the eyes in eight cases, with a 2-year time to ocular relapse of 59+/-11%. Ocular failure was less common in patients treated with chemotherapy plus ocular irradiation and was associated with a significantly shorter survival. Seven patients are alive [median follow-up 53 months, 2-year overall survival (OS): 39+/-11%] , five of whom were treated with ocular irradiation. The patient with isolated IOL is alive and disease-free at 14 months. OS of the entire series was similar to that of PCNSL patients with negative slit-lamp examination. CONCLUSIONS: IOL is usually associated with concomitant brain disease and shows a survival similar to that of the rest of PCNSLs. Chemotherapy combined with ocular irradiation resulted in better control of ocular disease, which seems to be associated with survival. In view of the potential role of ocular irradiation, the use of chemotherapy alone in phase II trials should be critically reconsidered in PCNSL patients with ocular disease.
BACKGROUND: Following our previous study of CHOP (cyclophosphamide, doxorubicin, vincristine and prednisone) intensification in non-Hodgkin's lymphoma (NHL), in the present report we attempted to further increase dose intensity by shortening the between-course intervals with the support of growth factors. PATIENTS AND METHODS: A total of 67 patients were enrolled. With a fixed dose of doxorubicin 75 mg/m(2), cyclophosphamide (CTX) was started at a dose of 1750 mg/m(2) and increased by 250 mg/m(2) in consecutive cohorts of patients provided that no dose-limiting toxicity occurred. After the maximal tolerated dose (MTD) had been identified, this was used to treat more patients in order to confirm the feasibility of the regimen on a large scale, with the number of cycles being varied on the basis of disease extension. RESULTS: Twenty-three cases were enrolled in the CTX dose finding phase. Dose-limiting non-hematological toxicity occurred at 2250 mg/m(2). As the intermediate level of 2000 mg/m(2) had a borderline toxicity profile, a CTX dose of 1750 mg/m(2) was defined as the MTD. A total of 53 patients then received the MTD during the course of the study as a whole. At the MTD, toxicity was acceptable. Only 10 of 189 cycles (4%) required hospitalization due to infection or febrile neutropenia. Seventy-four percent of the patients achieved complete remission. Freedom from progression and overall survival at 12 months were 71% and 86% in the whole series, and 58% and 71% for high-risk cases, respectively. CONCLUSIONS: This intensified CHOP regimen is feasible on an outpatient basis. It can be safely considered a definitive treatment in patients at low and intermediate risk, and as induction before high-dose consolidation in high-risk cases.
BACKGROUND: Highly active antiretroviral therapy (HAART) is strongly effective in reducing morbidity and mortality in HIV-1-positive individuals. Its main drawback is the potential toxicity. Data on the frequency and determinants of severe hepatotoxicity in a clinical setting are still sparse. METHODS: This is a prospective study of HIV-1-positive individuals with known HBsAg and HCV-Ab serology. The study end point was progression to alanine aminotransferase (ALT) levels > or =200 IU/L after HAART initiation. Cumulative probability of progression to this end point was estimated by the Kaplan-Meier method. Crude and adjusted hazard ratios (HR) were estimated by proportional hazards regression model. RESULTS: One thousand two hundred fifty-five patients were included. HBsAg was found in 91 (7.2%), HCV-Ab in 578 (46.5%) patients; almost all injection drug users (451 of 482; 93.6%) were HCV-Ab positive. Sixty-one individuals progressed to the end point with a probability of 7.9% (95% confidence interval [CI], 5.6-10.0) of progression at 24 months from starting. Independent factors predicting progression to the end point were baseline ALT levels (HR, 5.29; 95% CI, 3.24-8.65; every 10 IU/L higher), HCV-Ab positivity (HR, 4.01; 95% CI, 1.48-10.85) or both HBsAg and HCV Ab positivity (HR, 3.85, 95% CI, 1.01-14.61), and previous non-HAART therapy (HR, 1.84, 95% CI, 1.04-3.42). Patients receiving stavudine-containing regimens had a lower risk than those receiving zidovudine-containing regimens (HR, 0.30, 95% CI, 0.12-0.71). CONCLUSIONS: There was a low risk of ALT > or =200 IU/L in our cohort. Hepatitis C coinfection and elevated ALT levels at HAART initiation are important predictors of progression to ALT > or =200 IU/L; stavudine-containing regimens were associated with a lower risk compared with zidovudine-containing regimens.
BACKGROUND: The role combination therapy with interferon alfa-2b and tribavirin (US: ribavirin) plays in producing sustained virological responses in patients with HIV and chronic hepatitis C (HCV) infection is still unknown. OBJECTIVES: To determine the feasibility and sustained response of interferon alfa-2b and tribavirin combination therapy. DESIGN: Phase II study. METHODS: Seventeen patients were enrolled at the National Cancer Institute, Aviano, Italy and received combination therapy with interferon alfa-2b 3 MIU subcutaneously three times a week plus tribavirin 1000-1200 mg/day for 24 weeks. Antiretroviral therapy was concomitantly given in all but one patient. RESULTS: At the end of treatment, five (31%) patients achieved clearance of HCV RNA and 11 (69%) showed normalized liver function enzyme levels. In three patients, serum HCV RNA concentration was still undetectable 24 weeks after treatment, with an overall sustained virological response rate of 19% The serum liver enzymes were still normal in 10 patients 24 weeks after treatment, the overall sustained biochemical response rate being 62% All patients with HCV RNA clearance at the end of treatment and 24 weeks after treatment had a concomitant biochemical response. Overall the combination treatment was well tolerated. CONCLUSIONS: Our data confirm that the combination of interferon alfa-2b and tribavirin is well tolerated and feasible in patients with HIV-HCV co-infection and it can be associated safely with highly active antiretroviral therapy. The sustained response achieved with the drug combination does not seem to be any better than that achieved with 12 months of monotherapy with interferon alfa-2b.
BACKGROUND: The prognosis of patients with human immunodeficiency virus (HIV)-related non-Hodgkin lymphoma (NHL) is poor. In fact, despite a high complete response (CR) rate, approximately 50% of these patients die from progressive lymphoma. METHODS: From November 1994 to April 2000, the authors treated 40 patients with resistant or recurrent HIV-related NHL with a 96-hour continuous intravenous infusion of cyclophosphamide (187.5 mg/m(2) per day), doxorubicin (12.5 mg/m(2) per day), and etoposide (60 mg/m(2) per day). RESULTS: The median number of cycles administered was two (range, one to six cycles). A CR was documented in 4 of 40 patients (10%), and a partial remission (PR) was documented in 7 of 40 patients (18%). The CR median duration was 6 months (range, 4--30+ months), whereas PRs lasted for 5 months (range, 2--8 months). The overall median survival was 4 months (range, < 1--33 months), and the median survival for responding patients was 10 months. CONCLUSIONS: The current data confirm that infusional cyclophosphamide, doxorubicin, and etoposide is active in patients with refractory or recurrent HIV-related NHL. However, the median survival of these patients remains poor, and the other innovative approaches should be used.
To assess whether the incidence of invasive cervical cancer (ICC) has changed as a result of highly active antiretroviral therapy (HAART), we conducted a prospective cohort study on the incidence of ICC before and after the introduction of HAART among Italian women with a known duration of HIV infection. We estimated the incidence per 1000 person years of ICC as a first AIDS-defining disease for the periods 1981 through 1991, 1992 through 1995, and 1996 through 1998. We also estimated the incidence of other first AIDS-defining diseases. Kaplan-Meier and Cox models were applied to compare the periods 1981 through 1995 and 1996 through 1998 in terms of cumulative incidence and relative hazards (RHs). The analysis included 483 women (median follow-up: 7 years). In the period 1981 through 1995, a trend of increase was observed in the incidence of ICC and other AIDS-defining diseases; this trend has continued only for ICC, whereas the incidence of other AIDS-defining diseases has decreased since 1996. Compared with 1981 through 1995, the RH of ICC for 1996 through 1998 was 7.41 (95% confidence interval [CI]: 1.21--45.44); when adjusting for age at HIV seroconversion, the RH decreased to 4.75 (95% CI: 0.80--28.24). It remains to be determined whether the continued increase in ICC incidence after the introduction of HAART is attributable to a decreasing competitive mortality from other AIDS-defining diseases among HIV-infected women.
Human herpesvirus 8 (HHV8), which has been suggested as the causal agent of Kaposi's sarcoma (KS), has also been implicated in the pathogenesis of sarcoidosis. We describe a patient affected concomitantly by sarcoidosis and KS. HHV8 sequences were detected with PCR only on KS lesions, whereas sarcoid tissues did not harbor HHV8 DNA. Immune dysfunction related to sarcoidosis may have facilitated the oncogenic role of HHV8 and the development of KS.

This study was aimed at defining the histogenesis of the pathologic spectrum of lymphoma arising in the context of human immunodeficiency virus (HIV) infection. Toward this aim, 87 AIDS-related non-Hodgkin lymphomas (AIDS-NHL) and 16 Hodgkin lymphomas arising in HIV+ patients (HIV-HL) were comparatively analyzed for the expression pattern of several B-cell histogenetic markers, including BCL-6 (expressed by centroblasts and centrocytes), MUM1/IRF4 (expressed by late centrocytes and post-germinal center [GC] B cells), and CD138/syn-1 (expressed by post-GC B cells). Expression of MUM1, BCL-6, and syn-1 segregated 3 major phenotypic patterns among AIDS-NHL and HIV-HL: (1) the BCL-6+/MUM1-/syn-1- pattern, selectively clustering with a large fraction of AIDS-Burkitt lymphoma (17 of 19) and of systemic AIDS-diffuse large cell lymphoma (12 of 16); (2) the BCL-6-/MUM1+/syn-1- pattern, associated with a fraction of AIDS-immunoblastic lymphoma (8 of 24); and (3) the BCL-6-/MUM1+/syn-1+ pattern, associated with systemic and primary central nervous system immunoblastic lymphoma (14 of 24) and with primary effusion lymphoma (10 of 10), plasmablastic lymphoma of the oral cavity (7 of 7), and HIV-HL (15 of 16). Analysis of nonneoplastic lymph nodes showed that the 3 phenotypic patterns detected in AIDS-NHL and HIV-HL correspond to distinct stages of physiologic B-cell development-centroblasts (BCL-6+/MUM1-/syn-1-), late GC/early post-GC B cells (BCL-6-/MUM1+/syn-1-), and post-GC B cells (BCL-6-/MUM1+/syn-1+). Expression of the Epstein-Barr virus-encoded latent membrane protein-1 clustered with the BCL-6-/MUM1+/syn-1+ profile throughout the clinicopathologic spectrum of AIDS-NHL and HIV-HL. Overall, these results define novel histogenetic subsets of AIDS-NHL and HIV-HL and may provide novel tools for refining the diagnosis of these disorders.
BACKGROUND: The feasibility and efficacy of concomitant chemotherapy and highly active antiretroviral therapy (HAART) is still unknown in patients with human immunodeficiency virus (HIV)-related malignancies. To evaluate the impact of chemotherapy plus HAART on the clinical course of patients with HIV-related, systemic, non-Hodgkin lymphoma (HIV-NHL), the authors compared retrospectively a group of 24 patients with HIV-NHL who were treated with the cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) chemotherapy regimen plus HAART with a group of 80 patients who were treated with CHOP chemotherapy or a CHOP-like regimen (i.e., cyclophosphamide, doxorubicin, teniposide, and prednisone with vincristine plus bleomycin) without receiving antiretroviral therapy. METHODS: All patients were enrolled in two sequential trials performed at the Aviano Cancer Center, Italy, from April 1988 to December 1998. HAART was included with combination therapy from January 1997. Antiretroviral regimens consisted of two reverse transcriptase inhibitors and one protease inhibitor. RESULTS: The two treatment groups were well matched with regard to patient demographics, NHL characteristics, HIV status, and treatment, i.e., the number of cycles and chemotherapy dose. The response rates were similar between the two groups. Severe anemia (Grade 3-4 according to the World Health Organization criteria) was significantly greater in the patients who received CHOP-HAART compared with the patients who received CHOP alone (33% vs. 7%, respectively; P = 0.001). Leukopenia was similar between the two groups, but colony stimulating factor support was significantly greater in the CHOP-HAART group than in the control group (92% vs. 66%, respectively; P = 0.03). Seventeen percent of CHOP-HAART patients developed severe autonomic neurotoxicity, whereas none of the CHOP patients developed neurotoxicity (P = 0.002). At similar median follow-up, opportunistic infection (OI) rates and mortality were significantly lower in the CHOP-HAART patients than in the CHOP patients (18% vs. 52%, respectively; P = 0.05; and 38% vs. 85%, respectively; P = 0.001). The median survival for CHOP-HAART patients was not reached, whereas the medial survival of CHOP patients was 7 months (P = 0.03). CONCLUSIONS: The combination of CHOP plus HAART is feasible and may reduce the morbidity from OIs in HIV-NHL patients. However, careful attention must be directed to cross toxicity and possible pharmacokinetic interactions between antiretroviral and antineoplastic drugs. The impact of the combined chemotherapy plus HAART treatment on patient survival needs urgently to be evaluated in prospective studies.
